[Title] Molecular imaging of bcl-2 expression in small lymphocytic lymphoma using 111In-labeled PNA-peptide conjugates.

The bcl-2 gene is overexpressed in non-Hodgkin's lymphoma (NHL), such as small lymphocytic lymphoma (SLL), and many other cancers.

In vitro studies were performed in Mec-1 SLL cells, which express both bcl-2 messenger RNA and somatostatin receptors.

Biodistributions and microSPECT/CT studies were performed in Mec-1-bearing SCID (severe combined immunodeficiency) mice, a new animal model of human SLL.

CONCLUSION: A new (111)In-labeled antisense PNA-peptide conjugate demonstrated proof of principle for molecular imaging of bcl-2 expression in a new mouse model of human SLL.

[Title] Initial diagnosis of small lymphocytic lymphoma in parotidectomy for Warthin tumour, a rare collision tumour.

Warthin tumours (WT) and malignant lymphomas are only rarely associated, and most are examples of involvement of the lymphoid stroma of WT by a disseminated lymphoma.

This report describes a case where excision of a parotid mass led to the initial diagnosis of WT and small lymphocytic lymphoma (SLL).

The diagnosis of SLL was confirmed by immunohistochemistry and molecular studies.

This case highlights the extremely rare association of SLL with WT and the importance of evaluation of the WT stroma, where the pale proliferation centres of SLL may mimic germinal centres of reactive lymphoid nodules.

[Title] Multiple lymphomatous polyposis associated with small lymphocytic lymphoma: a unique presentation.

Multiple lymphomatous polyposis (MLP) is a rare extra-nodal manifestation of lymphoma.

In most cases, MLP is associated with mantle cell lymphoma (MCL).

We report a 66-year-old male diagnosed with small lymphocytic lymphoma (SLL)/chronic lymphocytic lymphoma (CLL), who showed evidence of rectal bleeding.

A CT-scan of the abdomen and pelvis showed an enlarged spleen, multiple paraaortic and mesenteric lymph nodes, and some diverticular pouching along the antimesenteric border of the pelvic colon.

A colonoscopy revealed the presence of multiple polypoid lesions, biopsies of which showed diffuse lymphoid infiltrate without any identifiable follicles.

Immunohistochemical analysis combined with a Fluorescence In-Situ Hybridization (FISH) study excluded the diagnosis of MCL.

A bone marrow aspiration biopsy demonstrated diffuse infiltration of the bone marrow with low grade lymphocytes that expressed CD 20, CD5 and CD23, with negative BCL-1, t (11;.

A diagnosis of B-cell CLL with kappa light chain restriction was made.

Multiple lymphomatous polyposis is considered to be a digestive counterpart to MCL and can therefore be considered as a presentation of MCL.

The patient's bone marrow revealed a B-cell lymphoma of CLL/SLL phenotype, which to our knowledge has not been linked to MLP in previously reported cases.

[Title] Chronic lymphocytic leukaemia and small lymphocytic lymphoma: overview of the descriptive epidemiology.

The 2001 World Health Organization classification scheme considers B-cell chronic lymphocytic leukaemia (CLL) and small lymphocytic lymphoma (SLL) in an aggregate category (CLL/SLL) because of shared clinicopathological features.

We have estimated age-adjusted incidence rates (IRs) of CLL and SLL in the population-based Surveillance, Epidemiology and End Results Program in the United States to analyse patterns of CLL and SLL separately and jointly.

Age-standardized to the 2000 US population, overall IRs were 3.83 per 100 000 person-years for CLL (n = 15 676) and 1.31 for SLL (n = 5382) during 1993-2004.

Incidence of the combined entity, CLL/SLL, was 90% higher among males compared to females, and the male:female IR ratio was significantly higher for CLL (1.98) than for SLL (1.67).

CLL/SLL IRs were 25% and 77% lower among Blacks and Asian/Pacific Islanders, respectively, compared to Whites.

A significant reporting delay was evident for CLL but not for SLL, so that CLL/SLL temporal trends must be interpreted cautiously.

CLL and SLL IRs increased exponentially with age among all gender/race groups, with CLL IRs increasing more steeply with advancing age than SLL.

[Title] Chromosomal abnormalities detected by multicolor fluorescence in situ hybridization in fine-needle aspirates from patients with small lymphocytic lymphoma are useful for predicting survival.

BACKGROUND: Fine-needle aspiration (FNA) of lymph nodes is commonly used to assess disease progression in patients with small lymphocytic lymphoma (SLL).

Although cytologic features are helpful for diagnosing typical SLL and transformed large-cell lymphoma (tLCL), SLL in accelerated phase (SLLacc) is more difficult to diagnose.

Additional tests are needed to identify those patients who are transforming to a higher-grade lymphoma.

This study evaluated the use of a multicolor fluorescence in situ hybridization (FISH) probe panel specifically designed for chronic lymphocytic leukemia (CLL)/SLL and assessed the association between FISH findings and cytologic diagnosis, proliferation index, and risk of death.

METHODS: FNA specimens from 50 patients (32 men and 18 women; mean age, 57 years [range, 36-77 years]) with histologically confirmed CLL and/or SLL were evaluated in this study for chromosomal abnormalities of 11q22 (ATM), 12, 13q14.3, 13q34.3 (LAMP1), and 17p13.1 (p53) by using a multiprobe FISH kit.

The FISH findings were compared with the cytologic diagnoses (26 SLLs, 12 SLLaccs, and 11 tLCLs), Ki-67 immunostaining, and risk of death.

CONCLUSIONS: FISH can be performed on FNA specimens from patients with a history of SLL/CLL.

Knowledge of genetic abnormalities from FNAs may be useful in deciding when and how to treat indolent or progressive SLL.

[Title] Simultaneous occurrence of peripheral T-cell lymphoma unspecified and B-cell small lymphocytic lymphoma. Report of 2 cases.

We report on 2 composite lymphomas occurring in elderly patients, morphologically characterized by the combination of peripheral T-cell lymphoma (PTCL) unspecified and B-cell small lymphocytic lymphoma.

Immunohistochemistry provided objective confirmation of the coexistence of the 2 malignancies, as did molecular biology by revealing clonal T-cell receptor gamma and immunoglobulin heavy chain gene rearrangements.

One of the patients had no history of indolent lymphoma either at the personal and family level, whereas the other showed a strong familial predisposition, his mother and sister having suffered from B-cell chronic lymphocytic leukemia.

To the best of our knowledge, the simultaneous occurrence of PTCL unspecified and B-cell small lymphocytic lymphoma is an exceptional event; the possible pathogenetic correlations between the 2 neoplasms are discussed.

[Title] Micronodular T-cell/histiocyte-rich B-cell lymphoma of the spleen in a case of small lymphocytic lymphoma: a Richter's transformation.

Abstract A case of micronodular T-cell/histiocyte-rich B-cell lymphoma of the spleen who had a prior diagnosis of small lymphocytic lymphoma is presented.

Micronodular T-cell/histiocyte-rich B-cell lymphoma of the spleen was first described in 2003, and very few cases have been reported since then.

This is the first reported case supervening in a patient with pre-existing chronic lymphocytic lymphoma.

We review its clinical, pathologic, and immunohistochemical features and the difficulties we encountered during diagnosis.

[Title] Fine-needle aspiration biopsy findings in patients with small lymphocytic lymphoma transformed to hodgkin lymphoma.

Although small lymphocytic lymphoma (SLL) is an indolent lymphoma, approximately 5% of cases can transform to a higher-grade lymphoma, rarely Hodgkin lymphoma (HL).

We report the fine-needle aspiration (FNA) results of 6 cases of SLL/chronic lymphocytic leukemia (CLL) that transformed to HL.

The patients included 5 men and 1 woman, ranging in age from 49 to 72 years at the time of SLL/CLL diagnosis with time for development of HL ranging from 0 to 95 months (mean, 49.3 months).

The FNA diagnoses were SLL with HL transformation (2 cases), SLL with large atypical cells (1 case), and atypical lymphoid proliferation with large atypical cells (3 cases).

Flow cytometry performed in 5 cases (2 FNA specimens) demonstrated a monoclonal B-cell population with CD19/CD5 coexpression.

The presence of large atypical mononucleated and binucleated cells in lymph node FNA specimens from patients with SLL/CLL with progressive adenopathy should raise the possibility of transformation to HL.

A diagnosis of an interdigitating dendritic cell tumor of the lymph node and a B-cell small lymphocytic lymphoma occurring in the same anatomic location was made.

We found that although rare cases of interdigitating dendritic cell tumor with an associated secondary malignancy have been described in the literature, to our knowledge, this is the first report of interdigitating dendritic cell tumor and synchronous neoplasm diagnosed at the same site.

Ongoing phase 1 studies of ABT-263 show anti-tumor activity in CLL and some lymphomas (Wilson W et al, ASH. 2008).

We tested 2 strategies to mitigate variability in circulating platelet levels and achieve higher cumulative exposure: introducing a lower lead-in dose and using a continuous dosing (CD) (21/21 d schedule).

For pts receiving 150 mg lead-in, nadir occurred during this phase, and platelet levels remained relatively stable on CD for doses up to 225 mg.

While CD enrollment and time on study is still limited, anti-tumor activity includes 1 unconfirmed partial response (68% CT regression) in a SLL pt at 275 mg and 3 CLL pts with ≥50% lymphocyte reduction for ≥2 months.

[Title] ABT-263 activity and safety in patients with relapsed or refractory lymphoid malignancies in particular chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL).

ABT-263 displays activity (EC₅₀ ≤ 1μM) against human lymphoid and small cell lung cancer cell lines.

Mechanism based preclinical toxicities include reductions in circulating lymphocytes, apoptosis of circulating platelets, and decreased spermatogenesis, mediated by inhibition of Bcl-2, Bcl-X_L, and Bcl-w, respectively.

Among 27 CLL/SLL pts, 3 have confirmed radiographic partial responses (PR) (99%, 92% and 72%) and 2 have unconfirmed regressions, 51% and 72%.

6 pts maintained a ≥50% decrease in circulating lymphocytes for ≥ 2 months and 11 pts have stable disease; of these 5 experienced minor radiographic responses (range of 36% to 49%).

In addition, among 40 (M06-814) lymphoma pts, 3 with follicular lymphoma achieved PR and one had a minor response (49% regression).

With CD dosing (16 pts), activity includes 1 unconfirmed PR in SLL & and 3 CLL pts with ≥50% lymphocyte reduction for ≥2 months duration.

CONCLUSIONS: ABT-263 showed favorable PK and safety profiles with anti-tumor activity in relapsed/refractory CLL/SLL and follicular lymphoma.

[Title] A phase I trial of TRU-016, an anti-CD37 small modular immunopharmaceutical (SMIP) in relapsed and refractory CLL.

Pre-clinical studies have demonstrated CD37 SMIP mediates significantly greater direct and NK-cell mediated killing of CLL cells as compared to other therapeutic antibodies used in CLL.

METHODS: Patients with relapsed/refractory CLL or SLL who had adequate organ function, platelets > 30,000/mm³ were eligible.

Dose escalation and de-escalation is based on CTC AE toxicity grades.

Two patients had partial clearing of leukemia cutis, and the other six had 27-94% reduction in peripheral lymphocyte count.

One pt. had an increase in Hgb of 40% and a reduction in lymph nodes of 36%.

CONCLUSIONS: To date, TRU-016 is a well tolerated treatment with minimal infusional toxicity and no observed dose limiting toxicity.

Encouraging reduction in tumor lymphocyte blood counts, lymph node/spleen size and improvement in normal hematopoeitic function in patients with high risk genomic CLL have already been observed at low, non-saturating doses of CD37.

[Title] Chronic lymphocytic leukemia (CLL) coexistent with HIV: An increasing association?

METHODS: Cases of HIV-associated CLL/small lymphocytic leukemia (SLL) were collected from the authors' archives and published case reports (using PubMed search).

Information regarding patient demographics (age, gender), mode of HIV acquisition, HAART use, immunosuppression (HIV Viral load [VL], CD4+ cell count), clinical presentation, pathology, and outcome were abstracted and analyzed.

CLL/SLL was diagnosed by lymph node biopsy (n = 1) and/or flow cytometry (n = 5).

Two patients remained well without treatment and 4 required therapy due to either hemolytic anemia, CLL- induced renal failure, pancytopenia, or hypogammaglobulinemia with recurrent infections.

CONCLUSIONS: CLL/SLL may occur in association with HIV infection in the elderly without significant concomitant immunosuppression.

CLL-related complications in our small series were frequent (67%), including mortality (50%).

Additional cases of CLL/SLL are anticipated as HIV-infected patients in the HAART era are reported to be living longer.

[Title] Community-based phase II trial of pentostatin, cyclophosphamide, and rituximab (PCR) biochemotherapy in chronic lymphocytic leukemia and small lymphocytic lymphoma.

We conducted a multicenter, community-based phase II trial of PCR biochemotherapy (pentostatin 4 mg/m2, cyclophosphamide 600 mg/m2, and rituximab 375 mg/m2) every 3 weeks for up to 6 cycles in patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).

PCR is active in CLL/SLL, but appears to be less active and associated with more complications in the community setting, compared to trials with younger, lower risk patients who travel to academic referral centers for treatment.

[Title] [Well-differentiated lymphocytic lymphoma of the prostate. Case report and bibliographic review].

[Transliterated title] Linfoma linfocítico, bien diferenciado de la próstata, presentación de un caso y breve revisión de la literatura.

OBJECTIVE: To report a case of prostate lymphoma and a brief review of the literature.

Surgery with retropubic prostatectomy was performed, and pathology revealed a primary prostate lymphoma.

The case study is followed by a brief bibliographic review, where we analyse clinical menifestations of this entity, complementary studies useful for diagnosis (laboratory test, trasrectal prostate biopsy, transuretral resection, ultrasound and computerised axial tomography), treatment options (surgery, polychemotherapy, radiotherapy) as well as survival in these patients.

CONCLUSIONS: Of the cases reviewed, mean age at diagnosis was 57 years.

Clinical debut was with prostate symptoms, with or without AUR and sometimes manifestations of renal failure due to obstructive uropathy, as well as general symptoms (astenia, anorexia, weight loss).

PSA values remain unaltered in prostate lymphoma patients.

Histologic diagnosis may be made by transrectal prostate biopsy, although transurethral resection (TUR) may be necessary for confirmation.

Ultrasound and CT scan are of great utility for diagnosis of both local and distant tumors.

From a therapeutic point of view, surgery for the obstruction of the lower urinary tract (TURP or retropubic prostatectomy) may be necessary, as well as the cyclophosphamide based polychemotherapy with corticosteroids and other cytostatic agents, and radiotherapy; intratecal chemotherapy has also been used adjuvant bone marrow transplantation.

[Title] Cervical cancer coexisting with small lymphocytic lymphoma detected during positron emission tomography/computed tomography simulation: a case report.

CASE: A 63-year-old woman who was deemed inoperable due to carcinoma of the cervical stump extending to the parametria and paraaortic lymph nodes detected on MR images presented for extended field radiotherapy.

The excisional biopsy was consistent with small lymphocytic lymphoma (SLL).

CONCLUSION: In our case, PET/CT simulation not only led to changes in treatment management, but also revealed a very rare coexistence of SLL and invasive squamous cell carcinoma of the cervix.

[Title] Primary manifestation of small lymphocytic lymphoma in the prostate.

BACKGROUND: Infiltration of non-haematopoietic organs by small lymphocytic lymphoma/chronic lymphocytic leukaemia (SLL/CLL) is not unusual in late-stage disease and thus quite frequently encountered in post-mortem examinations.

However, primary manifestation of SLL/CLL in the prostate is rarely diagnosed.

PATIENTS AND METHODS: We report two cases of primary prostatic SLL/CLL, in one case in combination with prostate carcinoma, and discuss diagnostic pitfalls, pathophysiological mechanisms and therapeutic management, together with an overview of the literature.

CONCLUSIONS: Lymphocytic infiltration of the prostate associated with obstructive symptoms is rare but can already occur in very early disease.

Microscopically, SLL/CLL infiltration can be distinguished from chronic prostatitis by its pattern of infiltration and by immunohistochemistry.

As the incidence of both SLL/CLL and prostatic carcinoma increases with age, composite tumours might occur more often in the future.

[Title] Dietary factors and risk of chronic lymphocytic leukemia and small lymphocytic lymphoma: a pooled analysis of two prospective studies.

BACKGROUND: Other than male sex, family history, advanced age, and race, risk factors for chronic lymphocytic leukemia and small lymphocytic lymphoma (CLL/SLL) are unknown.

METHODS: Using two large prospective population-based studies, we evaluated the relationship between diet and CLL/SLL risk.

Among 525,982 men and women free of cancer at enrollment, we identified 1,129 incident CLL/SLL cases during 11.2 years of follow-up.

RESULTS: We found no associations between total fat, saturated fat, fiber, red meat, processed meat, fruit, or vegetable intake and risk of CLL/SLL.

We noted a suggestive positive association between body mass index and CLL/SLL (hazard ratio, 1.30; 95% confidence interval, 0.99-1.36).

CONCLUSION: We did not find any associations between food or nutrient intake and CLL/SLL.

IMPACT: Our large prospective study indicates that diet may not play a role in CLL/SLL development.

[Title] Expression of the human concentrative nucleotide transporter 1 (hCNT1) gene correlates with clinical response in patients affected by Waldenström's Macroglobulinemia (WM) and small lymphocytic lymphoma (SLL) undergoing a combination treatment with 2-chloro-2'-deoxyadenosine (2-CdA) and Rituximab.

In vitro studies of resistant human cell lines have confirmed that human concentrative nucleoside transporter 1 (hCNT1)-deficient cells display resistance.

EXPERIMENTAL DESIGN: We applied real-time PCR method to assess the mRNA expression of equilibrative and concentrative nucleoside transporter (hENT1, hCNT1), deoxycytidine and deoxyguanosine kinase (dCK, dGK), 5'-nucleotidase (5'-NT), ribonucleotide reductase catalytic and regulatory (RR1, RR2) subunits in bone marrow cells from 32 patients with Waldenström's Macroglobulinemia (WM) and small lymphocytic lymphoma (SLL) who received 2CdA-based chemotherapy.

RESULTS: All 32 patients enrolled expressed lower levels of hCNT1 as compared to healthy donors.

In univariate analysis, lower expression level of hCNT1 (p=0.0021) and RR2 (p=0.02) correlated with response to chemotherapy.

In particular, patients with low levels of hCNT1 achieved inferior clinical response.

This study suggests that nucleotidase expression levels can be used to identify subgroups of WM and SLL patients who will likely respond differently to a 2CdA-based therapy.

[Title] Assessment of chronic lymphocytic leukemia and small lymphocytic lymphoma by absolute lymphocyte counts in 2,126 patients: 20 years of experience at the University of Texas M.D. Anderson Cancer Center.

PURPOSE: Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are currently considered the same entity, but controversy remains over whether CLL and SLL should be treated similarly.

We assessed whether characteristics of patients with CLL and SLL differ in ways other than the absolute lymphocyte count (ALC) and evaluated treatment outcomes and prognostic factors.

METHODS: We searched the electronic database for patients with CLL or SLL who presented to The University of Texas M.D.

RESULTS: Among 2,126 consecutive CLL/SLL patients, 312 (15%) had ALC less than 5 x 10(9)/L.

CONCLUSION: Patients with CLL or SLL can be treated similarly.

[Title] Combination therapy with fludarabine and rituximab followed by alemtuzumab in the first-line treatment of patients with chronic lymphocytic leukemia or small lymphocytic lymphoma: a phase 2 trial of the Minnie Pearl Cancer Research Network.

BACKGROUND: The purpose of the current study was to evaluate the efficacy and toxicity of the combination of fludarabine and rituximab, followed by alemtuzumab, as first-line treatment for patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).

METHODS: In a nonrandomized phase 2 trial, 41 patients who had previously untreated CLL or SLL and required treatment received 4 cycles of the fludarabine and rituximab combination followed 5 weeks later by 4 weeks (12 doses) of intravenous alemtuzumab therapy.

RESULTS: Initial treatment with the combination of fludarabine and rituximab was well tolerated, and produced a 71% overall response rate (13% complete response).

[Title] Composite small lymphocytic lymphoma and extra-medullary myeloid tumor: a potential diagnostic pitfall.

Reported herein is a case of composite small lymphocytic lymphoma (SLL) and extramedullary myeloid tumor (EMT) occurring in the same lymph node.

Routine morphologic examination revealed a diffuse proliferation of small mature lymphocytes with numerous irregularly dispersed nodules, closely resembling SLL with prominent proliferation centers or Richter's transformation.

Flow cytometric immunophenotyping and immunohistochemical stains demonstrated the presence of SLL cells as well as myeloblasts, confirming the diagnosis of a composite SLL and EMT.

In conclusion, the occurrence of SLL and EMT in the same lymph node is rare and multiparameter approach is essential for a definitive diagnosis.

[Title] Small lymphocytic lymphoma involving an enlarging complex renal cyst.

Cervical lymph node biopsy had revealed small lymphocytic lymphoma.

Computed tomographic scan disclosed diffuse mesenteric and retroperitoneal adenopathy consistent with chronic lymphocytic leukemia, as well as a 4.5-cm complex cystic right renal mass, which 17 months later enlarged to 6.2 cm.

Partial nephrectomy revealed infiltration of the cyst wall by small lymphocytic lymphoma.

To our knowledge, this is the first reported case of lymphoma arising in or colonizing a renal cyst.

[Title] Autoimmune pancreatitis and concurrent small lymphocytic lymphoma: not just a coincidence?

Computed tomography imaging revealed fullness of the pancreatic head and multiple enlarged retroperitoneal lymph nodes.

Several enlarged lymph nodes in the aortocaval region and a firm hard mass in the pancreatic head were found.

Frozen section from one of the lymph nodes was suspicious for low-grade lymphoma.

The retroperitoneal lymph nodes were involved by small lymphocytic lymphoma.

DISCUSSION: Autoimmune pancreatitis is the most common benign diagnosis after pancreatic resection for presumed malignancy.

It has a well-documented association with autoimmune conditions, such as Sjögren's syndrome, inflammatory bowel disease, and sclerosing cholangitis.

Additionally, chronic lymphocytic leukemia-small lymphocytic lymphoma is often associated with autoimmune phenomena, most notably autoimmune hemolytic anemia.

However, an association between autoimmune pancreatitis and small lymphocytic lymphoma has not been previously described.

To our knowledge, this is the first reported case of a patient with concurrent autoimmune pancreatitis and small lymphocytic lymphoma.

[Title] A phase I/II study of rituximab and etanercept in patients with chronic lymphocytic leukemia and small lymphocytic lymphoma.

Rituximab has modest activity in relapsed chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma but is associated with tumor necrosis factor-alpha (TNF-alpha) release that can cause CLL proliferation and inhibit apoptosis.

The combination of etanercept and thrice weekly rituximab produces durable remissions in non-del(17p13.1) CLL patients and is well tolerated.

[Title] Indolent systemic mastocytosis associated with atypical small lymphocytic lymphoma: a rare form of concomitant lymphoproliferative disease.

Patients with systemic mastocytosis (SM) may acquire an associated hematologic non-mast cell (MC)-lineage disease (AHNMD).

In most cases, a myeloid neoplasm is diagnosed, whereas the occurrence of a lymphoproliferative disease is an extremely rare event.

We report on a patient with indolent SM associated with small lymphocytic lymphoma (SLL).

The patient presented with lymphadenopathy, maculopapular exanthema, and elevated serum tryptase.

The bone marrow biopsy showed focal MC aggregates together with SLL.

As assessed by immunostaining, neoplastic MC were found to exhibit CD117 and CD25 but did not display CD5 or CD20, whereas SLL cells were found to coexpress CD5 and CD20 but did not express MC antigens.

The KIT mutation D816V was detected in sorted CD34(+) cells and unfractionated marrow cells but not in CD5(+) SLL cells, confirming the coexistence of 2 distinct neoplasms.

[Title] [Bilateral tonsillar hypertrophy as the first manifestation of B cell-small lymphocytic lymphoma with interfolicular pattern].

[Transliterated title] Hipertrofia amigdalina bilateral como primera manifestación de linfoma de linfocitos pequeños B con patrón interfolicular.

B-cell small lymphocytic lymphoma typically involves nodal or extranodal tissues as a diffuse proliferation with proliferation centers (pseudofollicules) obliterating normal architecture.

But there are unusual patterns of involvement including interfollicular pattern that can be difficult to recognize histologically and probably represent partial or early involvement by neoplasm.

Tonsillar lymphoma usually presents either as a unilaterally enlarged palatine tonsil or as an ulcerative and fungating lesion over the tonsillar area.

Most lymphomas that involve the tonsil are diffuse large B cell lymphomas and primary low-grade lymphomas are exceptional.

We present a primary B-cell small lymphocytic lymphoma affecting palatine tonsils with interfollicular pattern in a 54 year-old man that clinically presented with symmetric / bilateral tonsillar enlargement and sleep apnea.

[Title] Fine-needle aspiration diagnosis of squamous cell carcinoma in a lymph node involved with small lymphocytic lymphoma: case report and review of the literature.

Diagnosis of two distinct malignant entities existing concurrently and at the same location (synchronous malignancy) by fine- needle aspiration (FNA) is unusual but may occur.

Small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL) in particular is associated with an increased incidence of secondary tumor, likely due to associated immunodeficiency.

Co-occurrence of some carcinomas such as squamous cell carcinoma (SCC), may show especially aggressive behavior.

A 57-year-old Caucasian male presented with recurrent upper extremity lymphedema and diffuse lymphadenopathy of the axillary and cervical regions.

FNA of a large cervical lymph node was diagnostic for both atypical lymphocytic proliferation and SCC.

Flow cytometric analysis showed the atypical lymphocytic proliferation to be positive for CD5, CD23, CD19, CD20, HLA-DR, CD38, and the population was kappa light chain restricted.

These cells were negative for CD-10 and FMC-7 antigens, suggesting a phenotype of B-cell SLL/CLL.

We report a rare occurrence of metastatic SCC to a lymph node infiltrated by SLL/CLL.

The diagnosis was achieved by a combination of cytomorphologic examination of FNA smears, immunohistochemical staining of cell block material, and flow cytometry on the sample obtained by FNA.

To the best of our knowledge, only three cases of SCC metastasis to SLL/CLL diagnosed by FNA have been reported in the English literature.

[Title] Systemic mastocytosis associated with small lymphocytic lymphoma: an incidental finding in a patient with invasive gastric adenocarcinoma.

We report an interesting case of systemic mastocytosis diagnosed incidentally in an omental lymph node in the setting of an invasive gastric adenocarcinoma.

The Diff-Quick touch preparation of the lymph node revealed abundant single cells and loose aggregates of cells with round to oval nuclei and deeply basophilic granules.

Monotonous proliferation of small mature lymphocytes and many eosinophils were also present in the background.

The frozen section and permanent sections of lymph node showed partial to complete replacement of lymph node by neoplastic mast cells.

[Title] AID protein expression in chronic lymphocytic leukemia/small lymphocytic lymphoma is associated with poor prognosis and complex genetic alterations.

The biological behavior of chronic lymphocytic leukemia and small lymphocytic lymphoma is unpredictable.

Nonetheless, non-mutated IgV(H) gene rearrangement, ATM (11q22-23) and p53 (17p13) deletion are recognized as unfavorable prognosticators in chronic lymphocytic leukemia.

The mRNA expression of activation-induced cytidine deaminase (AID), an enzyme indispensable for somatic hypermutation processes, was claimed to be predictive of non-mutated chronic lymphocytic leukemia cells in blood.

Here, we evaluated AID protein expression compared with known molecular and immunohistochemical prognostic indicators in 71 chronic lymphocytic leukemia/small lymphocytic lymphoma patients using a tissue microarray approach.

Twenty-five percent (17/69) of patients with AID-positive chronic lymphocytic leukemia/small lymphocytic lymphoma displayed a shorter survival than AID-negative chronic lymphocytic leukemia/small lymphocytic lymphoma patients (61 vs 130 months, P=0.001).

Taken together, our study shows that AID expression is an indicator of an unfavorable prognosis in chronic lymphocytic leukemia/small lymphocytic lymphoma patients, although it is not a surrogate marker for the IgV(H) status.

[Title] Synchronously diagnosed lymph nodal collision tumor of malignant melanoma and chronic lymphocytic leukemia/small lymphocytic lymphoma: case report.

We report a case of chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma and malignant melanoma (MM) occurring synchronously in the same lymph node.

To our knowledge this is the first time that synchronous occurrence of these two malignant processes in the same tissue is described.

In this case it is important that the melanoma was recognized in the excised lymph node, as this finding had much more critical treatment and long term survival consequences.

[Title] Serum leptin levels in childhood celiac disease.

OBJECTIVE: Leptin has effects on growth and is also involved in immune regulation.

We thought that with its intestinal histopathologic alterations due to immune mechanisms, and subsequent malnutrition and/or growth failure, celiac disease (CD) deserves interest regarding leptin status.

METHOD: Serum leptin levels of 19 children with CD on admission and 1 year after gluten-free diet (GFD) and of 16 healthy children were determined.

Mean serum leptin level of children with CD on admission and of healthy children were 1.60+/-0.63 ng/mL, and 3.98+/-1.49 ng/mL, respectively (P: 0.0001).

Mean serum leptin level under GFD was 4.55+/-1.97 ng/mL.

There was a statistical significant difference between serum levels determined before and 1 year after GFD (P: 0.001) and between those of under GFD and healthy children (P: 0.001).

Mean serum leptin level of children with Marsh IIIc and Marsh IIIa were not different (1.70+/-0.73 ng/mL vs. 1.45+/-0.59 ng/mL).

Leptin was correlated with body mass index in healthy children, and in CD both before and after GFD (P<0.001).

Serum leptin level was not correlated with lumbar z score either before or after GFD.

CONCLUSIONS: Serum leptin level is affected in childhood CD, it is not directly related to histopathologic findings, and is responsive to GFD.

Further studies investigating its level in different clinical and histopathologic presentations might give clear clues about the role of leptin in CD.

[Title] Renal cell carcinoma with non-Hodgkin's lymphoma infiltration: a case report.

The coexistence of renal cell carcinoma and non-Hodgkin's lymphoma is more common than expected in the general population; however, renal cell carcinoma with infiltration by non-Hodgkin's lymphoma has rarely been reported.

Here we report on a 77-year-old patient who presented with small lymphocytic lymphoma in the jugulodigastric lymph node.

On histopathological examination, the mass was diagnosed as a grade III renal cell carcinoma with infiltrated small lymphocytic lymphoma that was positive for B-cells (CD20).

[Title] Serum leptin levels in patients with allergic rhinitis.

OBJECTIVE: To investigate the serum leptin levels in patients with allergic rhinitis during the symptomatic period.

RESULTS: Leptin levels were 28.8 +/- 14.1 ng/mL in the patients with allergic rhinitis, and 20.8 +/- 13.5 ng/mL in the control group respectively.

CONCLUSION: Serum leptin levels were found to be significantly higher in patients with allergic rhinitis in symptomatic period.

SIGNIFICANCE: Apart from its primary role in the regulation of body weight and energy expenditure, leptin may have a role in the inflammatory process of the allergic rhinitis.

[Title] Outcome of cats with low-grade lymphocytic lymphoma: 41 cases (1995-2005).

OBJECTIVE: To evaluate factors associated with response to treatment, remission duration, and survival in cats with low-grade lymphoma affecting various organ systems.

SAMPLE POPULATION: 41 cats with histologically confirmed low-grade lymphocytic lymphoma.

PROCEDURES: Medical records and biopsy specimens of cats with histologically confirmed low-grade lymphocytic lymphoma of various organ systems treated with prednisone and chlorambucil between 1995 and 2005 were reviewed.

Seventy-eight percent of cats tested had low serum cobalamin concentrations.

Lymphoma was confined to the gastrointestinal tract in 68% of cats.

CONCLUSIONS AND CLINICAL RELEVANCE: Most cats with lymphocytic lymphoma responded to treatment with prednisone and chlorambucil, and most factors evaluated were not associated with outcome.

[Title] Increased trisomy 12 frequency and a biased IgVH 3-21 gene usage characterize small lymphocytic lymphoma.

Small lymphocytic lymphoma (SLL) and chronic lymphocytic leukemia (CLL) are considered as similar entity by the WHO classification.

We assessed the distribution of the four prognostic cytogenetic markers (deletion 11q23, 13q14, 17p13 and trisomy 12) and VH mutational status in 32 SLL and 119 CLL.

Trisomy 12 was most frequent (36% vs 13%, p=0.014) and 13q14 deletion was less frequent (9% vs 44%, p=0.001) in SLL in comparison with CLL.

An over representation of VH3-21 gene usage was found in SLL (17% vs 1%, p=0.011).

In conclusion, SLL show specific genetic markers that distinguish them from classical CLL.

[Title] Serum leptin levels in obsessive-compulsive disorder.

The aim of the present study was to evaluate serum leptin levels to demonstrate whether or not its eventual alterations might have an etiopathogenetic significance in patients with obsessive-compulsive disorder (OCD).

Thus, it was planned to examine whether serum leptin levels were affected by pure OCD (OCD-D), pure depression (D) or the comorbidity of OCD and depression (OCD+D).

Forty-four patients with OCD (27 with OCD-D and 17 with OCD+D), 38 depressed patients and 30 control subjects were enrolled and serum leptin and cortisol levels were measured.

According to the mean leptin levels, no significant difference was found between the OCD-D and control groups and between the OCD+D and D groups, while statistically significantly lower levels were found in the OCD+D and D groups than in control group.

Significant difference in the mean leptin levels was found among groups even after controlling for body mass index or sex.

The present study confirms the strong relationship between serum leptin and cortisol values and suggests that reduced leptin levels, rather than having an etiopathogenetic significance in patients with OCD, seem to be associated with patients with OCD and depression but not with pure OCD patients, and that OCD may be a heterogeneous subtype containing some biological indications of anxiety and affective disorders.

[Title] Diagnosis and prognosis of B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (B-CLL/SLL) and mantle cell lymphoma (MCL).

BACKGROUND: B-cell chronic lymphocytic leukemia/ small lymphocytic lymphoma (B-CLL/SLL) and mantle cell lymphoma (MCL) show many overlapping morphologic and immunophenotyping features, however they have great difference in therapeutic regimens and prognosis.

THE AIM OF THE STUDY: Is to determine the diagnostic and prognostic role of clinico-pathologic variables, CD23 and Cyclin D1 oncoprotiens in B-SLL/CLL and MCL.

PATIENTS AND METHODS: This study included 25 BCLL/ SLL cases and 25 MCL cases.

RESULTS: There was significant difference between BCLL/ SLL and MCL regarding several items including pattern of growth, where interfollicular pattern was restricted to B-SLL/CLL while nodular and mantle zone pattern were confined to MCL; pseudo-follicles were only present in B-CLL/SLL.

Transformed cells, plasmacytoid cells, peripheral blood lymphocytosis, significant longer survival and good prognosis were statistically more prominent in favor of B-CLL/SLL.

On the other hand, cell cleavage, epithelioid histiocytes, plasma cells, naked nuclei, hyalinized venules, deposited hyaline material in background and reticular fibers in addition to higher mitotic index per 20 HPF were more significantly identified in favor of MCL.

CD23 was expressed as membranous pattern in 16/25 (64%) of B-CLL/SLL cases and 1/25 (4%) of MCL cases.

On the other hand, Cyclin D1 was expressed as nuclear staining in 18/25 (72%) of MCL cases and only 1/25 (4%) of B-CLL/SLL cases.

Regarding B-CLL/SLL, age >60 years and mitosis >or=10/20 HPF were independent prognostic factors of shorter survival by multivariate analysis.

CONCLUSION: Cyclin D1 is not only implicated in tumor genesis of MCL, but also in progression and extension of the disease when expressed in high levels (50% cut off value) and it seems to have prognostic impact in MCL.

This can be used as a basis for future therapeutic strategies targeting cell cycle regulators.

This study could support the concept that Cyclin D1 and CD23 immunostaining may be reliable diagnostic tools for discrimination between B-CLL/SLL and MCL.

[Title] Serum leptin level in hypothyroid males.

OBJECTIVE: To determine the correlation of serum leptin with thyroid hormones in primary hypothyroid male patients and euthyroid lean and obese control subjects.

Serum leptin was measured by ELISA and FT4, FT3 and TSH were measured by radioimmunoassay (RIA), triacylglycerol (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) by kit method, low density lipoprotein cholesterol (LDL-C) was calculated by the Friedwald s formula, and fasting blood sugar (FBS) by glucose oxidase method.

RESULTS: The mean +/- SEM values of leptin in male hypothyroid patients were 10.71+/-2.5 ng/ml, 8.27+/-1.91 in control group and 21.34+/-3.4 ng/ml in obese group, respectively.

No significant difference was found in serum leptin levels between hypothyroid patients and their age, BMI matched control group, while obese control group had significantly higher values of leptin (<0.05).

There was no significant correlation of leptin found with T4, T3, and TSH in hypothyroid patients and lean and obese control subjects.

This study observed that serum leptin level was significantly correlated with the BMI (r = 0.732, p < 0.005, r = 0.783, p < 0.005, r = 0.653, p < 0.005), in normal lean, obese and hypothyroid male patients respectively.

CONCLUSION: The results of this study suggest that there is no correlation between serum leptin and thyroid hormones in hypothyroid patients as well as in euthyroid subjects.

Serum leptin is directly related with BMI.

[Title] Preoperative serum leptin levels in patients with breast cancer.

Leptin is an adipocyte-derived protein and plays an important role in the control of body weight by acting as a neurohormone regulating energy balance and food intake in the hypothalamus.

The high serum leptin levels and the overexpression of leptin receptors have been documented in breast cancer patients, but the levels never checked preoperatively.

In the present study, the relationship between preoperative serum leptin levels of the breast cancer patients and the healthy controls were evaluated.

The serum leptin levels in 30 breast cancer patients were compared to 30 healthy female volunteers.

In addition, the association of serum leptin levels and the various well-known risk factors were studied.

Serum leptin levels of patients with breast cancer (28.55 + 19.7 ng/ml) were tended to be higher than those of controls (26.43 + 19.4 ng/ml), but it did not reach statistical difference (P = 0.712).

There was significant correlation between the expression of ER, PR, and serum leptin levels (P = 0.018 and 0.037, respectively), but not with the HER-2/neu receptor expression (P = 0.067).

Also association was not found between the tumor size, lymph node involvement, and the levels of serum leptin (P = 0.235, 0.34, and 0.86, respectively).

The serum leptin level was also found to be similar in premenopausal (24.85 +/- 18.14 ng/ml) and postmenopausal (30.49 +/- 17.19 ng/ml) patients (P = 0.235).

The preoperative serum leptin levels in breast cancer patients were similar to healthy controls.

In subset analysis, the significant correlation between the leptin level and hormonal status was noted, but association with HER-2/neu was not detected.

[Title] Programmed death 1 is a marker of angioimmunoblastic T-cell lymphoma and B-cell small lymphocytic lymphoma/chronic lymphocytic leukemia.

PD-1 expression was recently reported in some T-cell non-Hodgkin lymphoma (NHL) subtypes, but the expression profile of PD-1 and its ligands (PD-L1 and PD-L2) in B-NHLs remains largely to be characterized.

A series of 161 lymphoma tissue and 11 blood samples was analyzed using either immunohistochemistry or flow cytometry.

In reactive lymph nodes, PD-1 was mainly expressed in follicular T cells.

In B-NHLs, PD-1 was mainly expressed in reactive T cells; but expression was also noted in neoplastic B cells from small lymphocytic lymphoma (SLL, 12/13), grade III follicular lymphoma (3/3), and diffuse large cell lymphoma (2/25).

In contrast, neoplastic B cells from mantle cell lymphoma (0/11), marginal zone lymphoma (0/12), Burkitt lymphoma (0/3), and grade 1 to 2 follicular lymphoma (0/40) were PD-1 negative.

PD-L1 and PD-L2 were negative in small B-cell lymphomas, including B-SLL.

Flow cytometry showed that blood cells from chronic lymphocytic leukemia (B-CLL) also displayed PD-1 expression, which could be increased by CD40 stimulation.

These results show that PD-1 expression among B-NHLs is mainly associated with SLL/CLL and is influenced by activation of the CD40/CD40L pathway.

Because the anti-PD-1.6.4 antibody works on paraffin sections, it represents a useful tool to differentiate SLL/CLL from other small B-cell lymphomas.

[Title] Serum leptin levels in patients with nasal polyposis.

OBJECTIVES: The aim of this study was to investigate the serum leptin levels in patients with nasal polyposis.

RESULTS: Serum leptin levels were 12.10 +/- 9.39 ng/ml in the nasal polyposis patients and 6.17 +/- 7.68 ng/ml in the controls.

A significant difference (p = 0.021) was observed in the mean serum leptin levels between nasal polyposis patients and controls.

CONCLUSION: Serum leptin levels were found to be significantly higher in patients with nasal polyposis.

Leptin, apart from its primary role in the regulation of body weight and energy expenditure, may have a role in the inflammatory response of nasal polyposis.

[Title] Serum leptin levels in women with uterine leiomyomas.

OBJECTIVE: The purpose of this study was to examine the influence of leptin in women with uterine myoma.

In all subjects, FSH, LH, E2, prolactin, hemoglobin, hematocrit, blood urea nitrogen, creatinine, fasting glucose, CA125, and leptin were examined, and body mass index (BMI) was calculated.

RESULTS: Although leptin level was higher in the myomatic women (5.73 +/- 4.08 ng/mL) than in the normal women, there was no statistically significant difference (p = 0.303).

Also, no statistical difference in the ratios of leptin/BMI was found in both groups.

A significant correlation was found between high E2 level and myoma uteri (p = 0.021).

Hemoglobin levels were significantly lower in the myomatic women (p = 0.044).

When we compared the leptin levels according to BMI, leptin levels were higher in patients who had BMI > 30 (p = 0.02).

CONCLUSION: We did not find any significant difference in serum leptin levels between the two groups.

But leptin may have an indirect role in the pathogenesis of uterine leiomyoma.

So further research is needed to reveal the role of leptin in myoma uteri pathogenesis.

[Title] Effect of cyproheptadine on serum leptin levels.

Leptin is a 167 amino acid protein encoded by the obesity gene that is synthesized in adipose tissue and interacts with receptors in the hypothalamus linked to the regulation of appetite and metabolism.

Although both leptin and cyproheptadine are effective in controlling appetite, their interaction has not been addressed in clinical studies.

This study evaluated serum leptin concentrations in patients who received cyproheptadine to treat a variety of disorders.

Serum leptin levels were determined by leptin radioimmunoassay.

The mean body weight at baseline (52.59 kg) did not differ significantly from that at 1 week after treatment (52.84 kg; P > .05), but the mean leptin level after 1 week of treatment with cyproheptadine (3.14 ng/mL) was 14.2% higher than that at baseline (2.75 ng/mL; P < .05).

This increase may suggest that both leptin and cyproheptadine may affect appetite via similar receptors and that cyproheptadine does not impair leptin activity through these receptors.

[Title] Serum leptin levels in hypertensive disorder of pregnancy.

OBJECTIVE: To determine serum leptin levels in hypertensive disorder of pregnancy.

MATERIALS AND METHODS: In this prospective, cross-sectional, case control study, we measured serum leptin levels of 58 hypertensive pregnant women and 54 normal pregnant women.

We also did blood and urine analysis for the evaluation of the severity of hypertensive disorder of pregnancy.

We analysed the difference and correlation between anthropometric measures, hormonal and biochemical parameters, and serum leptin levels in two groups.

RESULTS: In the study group, serum leptin levels were determined to be higher than the control group.

While the serum uric acid, urea, aspartate aminotransferase, fibronectin, and fasting blood glucose levels were found to be higher, serum total protein and albumin levels were significantly lower among the hypertensive pregnant women.

Serum leptin levels were highly and positively correlated with serum fibronectin, and C peptide levels.

A negative significant correlation was observed between maternal serum leptin levels and neonatal birth weight among the pregnant women having the hypertensive disorders.

CONCLUSION: Serum leptin levels in hypertensive pregnant women appear to be higher.

The determination of serum leptin levels may be as important as serum fibronectin and C peptide levels in the management of hypertensive disorder of pregnancy.

C peptide and insulin may be due to hyperinsulinemia which leads to increased stimulation of leptin production by fatty tissue.

[Title] Serum leptin level in women with unexplained infertility.

INTRODUCTION: The aim of this study was to compare serum levels of leptin in women with unexplained infertility with fertile subjects.

MATERIAL AND METHOD: Serum leptin levels of 27 infertile and 30 fertile women on day 3 of the menstrual cycle were assessed and compared in this prospective age and body mass index (BMI) comparable controlled study.

The mean serum leptin level was significantly higher in women with unexplained infertility compared with fertile subjects.

Considering normal weight subjects, mean serum leptin levels were increased significantly in the unexplained infertile group compared with the fertile group (7.2 (range, 4.3-10.4) versus 3.5 (range, 1.9-6.2)ng/ml, respectively; p<0.0001, Mann-Whitney U-test).

The significant increase in serum leptin levels was observed also in overweight patients (6.8 (range, 1.3-5.2) versus 3.3 (range, 4.2-8.9)ng/ml, respectively; p<0.0001, Mann-Whitney U-test).

CONCLUSION: A significant difference in serum leptin levels between unexplained infertile and fertile women suggests that this cytokine may be involved in pathophysiology of unexplained infertility.

[Title] Serum leptin levels in acute myocardial infarction.

BACKGROUND: Several studies have shown an association of serum leptin levels with cardiovascular diseases.

The present study was undertaken to assess levels of serum leptin in patients presenting with acute ST segment elevation myocardial infarction.

The serum leptin levels in patients with myocardial infarction was 6.51 +/- 6.76 ng/ml versus 2.86 +/- 2.22 ng/ml in controls.

In the multivariate analysis the odds ratio for serum leptin with myocardial infarction was 1.45 with a 95% confidence interval of 1.2 to 1.8.

CONCLUSIONS: Our results suggest that serum leptin level is elevated in patients with acute ST segment elevation myocardial infarction.

[Title] Status of serum leptin levels in females with infertility.

OBJECTIVE: To assess serum leptin levels in infertile females referred to a tertiary care hospital in Pakistan.

Serum leptin levels of 44 infertile females were compared with 44 age matched fertile female controls.

RESULTS: The results revealed that serum leptin levels were significantly raised in infertile women (69.7+/-40.2ng/ml) as compared to fertile controls (41.1+/-27.3ng/ml) with p=0.000.

Moreover, a strong positive correlation was found between BMI and leptin levels as leptin levels increased with increase in BMI.

Mean leptin levels in overweight women were significantly higher (81.4+/-32.4ng/ml) as compared to normal weight women (30.6+/-20.6ng/ml) with p=0.000.

However, further studies are required to determine the exact mechanism by which enhanced body mass and serum leptin levels lead to female infertility.

[Title] [Serum leptin level in patients with obstructive sleep apnea-hypopnea syndrome].

OBJECTIVE: To investigate the effect of uvulopalatopharyngoplasty on changes of serum leptin levels in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS).

Pretreatment and post-uppp serum leptin concentrations in patients with OSAHS and in BMI-matched controls were measured by radioimmunoassay.

Correlations between leptin concentrations and AHI, BMI were analyzed.

RESULTS: The concentrations of leptin in patients with OSAHS were higher than that in controls (P < 0.05).

Mean levels (x+/-s) of leptin were (9.8+/-2.1) microg/L, (14.2+/-6.7) microg/L, and (19.3+/-7.9) microg/L in patients with severe, mediate and mild obstructive sleep apnea, respectively.

Serum leptin levels correlated positively with the degree of OSAHS as reflected by AHI (r = 0.

The leptin concentration of 51 responders after 6 months were significantly decreased (P < 0.01) than that of pre-operation.

However, the difference of leptin concentration between pre-operation and post operation was not significant in 9 nonresponders (P > 0.05).

CONCLUSIONS: There are higher leptin concentrations in patients with OSAHS, which are significantly correlated to the severity of disease.

Serum leptin levels in responders decreased significantly after uvulopalatopharyngoplasty.

OSAHS may influence the leptin system, resulting in increased serum leptin level.

[Title] Serum leptin levels during pregnancy in multiple sclerosis.

Leptin has been identified as a hormone that can influence inflammatory activity.

OBJECTIVE: The aim of this study was to investigate whether pregnancy-induced fluctuations of serum leptin levels differed between patients with MS and controls and whether serum leptin levels correlate with periods of enhanced and diminished disease activity.

Serum leptin and soluble leptin receptor (SLR) levels were measured using enzyme-linked immunosorbent assay.

RESULTS: Pre-pregnancy serum leptin levels were (mean +/- SD) 22.9 +/- 12.8 ng/ml in the MS group.

These levels increased in the third trimester to 28.5 +/- 15.0 ng/ml (P = 0.007).

The third trimester serum leptin levels in healthy women were comparable, 29.4 +/- 19.0 ng/ml.

Serum leptin levels after delivery dropped to 18.5 +/- 12.8 ng/ml in women with MS (P < 0.001) and to a lesser extend (22.0 +/- 17.5 ng/ml) in healthy women (P = 0.04).

SLR levels showed the same pattern.

Remarkably, women with the highest relative decrease in serum leptin levels after delivery had more often a postpartum relapse (P = 0.008).

CONCLUSION: In women with MS, leptin increased during late pregnancy.

A postdelivery drop in leptin levels was observed in both the MS and control group.

[Title] Extra-nodal small cell lymphocytic lymphoma of prostate: an unusual cause of lower urinary tract symptoms.

Malignant lymphoma of the prostate is a rare occurrence.

We describe a case of 60-year-old man presenting with acute urinary retention due to small cell lymphocytic secondary lymphoma of the prostate.

We present the clinical manifestation of the disease emphasizing that all lower urinary tract symptom (LUTS) cases should be evaluated for the potential that metastatic cancers or lymphomas may present with such a diagnosis.

[Title] Does tibolone affect serum leptin levels and body weight in postmenopausal women?

OBJECTIVES: Leptin has a significant role in body weight regulation and energy balance.

We examined the effect of tibolone on the body weight and serum leptin levels in postmenopausal women.

Absolute and body mass index (BMI)-corrected serum leptin concentrations and BMI values were measured at baseline, after 3 months, and after 6 months of the tibolone therapy.

RESULTS: Tibolone did not affect absolute and BMI-corrected serum leptin levels, and BMI values during the treatment.

A significant linear correlation between BMI values and serum leptin levels was observed (p<0.05, r=0.67).

CONCLUSIONS: Tibolone seems not to affect serum leptin levels, body weight and BMI values of postmenopausal women.

There is a significant correlation between serum leptin levels and BMI values.

[Title] [Changes in serum leptin levels in patients with surgically induced stress responses].

OBJECTIVE: To explore the effect of operative trauma induced stress responses on serum leptin levels.

METHODS: Serum samples of patients who had undergone resection of hepatic tumors or cholecystectomy were collected, and highly sensitive radioimmunoassay and enzyme-linked immunoadsorbent assay (ELISA) were used to determine serum levels of leptin, granulocyte-clone stimulating factor (G-CSF), C-reactive protein (CRP) and adrenocorticotropin hormone (ACTH) in the blood of these patients.

RESULTS: Compared with self-control before operation, serum leptin levels decreased slightly right after an abdominal operation (T0), it reached the highest level 1 day after operation (T1), and began to decrease from 2 days (T2) to 4 days after operation (T4), but the level was still higher than that before operation.

Serum leptin levels of patients undergoing laparoscopic operation showed no significant difference when compared with that of laparotomy patients.

G-SF levels decreased significantly after operation in both groups, and didn't recover to the levels before operation from T1 to T4.

CRP levels slightly decreased in both groups at T0, but increased significantly higher than the levels before operation from T1 to T4.

ACTH levels of decreased significantly in laparotomy patients from T0 to T1, and began to recover on T2, while that of laparoscopic operation patients showed no significant difference before and after operation.

CONCLUSION: Serum leptin levels of patients increase significantly and constantly subsequent to operative trauma induced stress responses, but this change has no correlation with that of CRP, G-SF and ACTH.

[Title] The spectrum of coincident entities with small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL) diagnosed by cytology.

BACKGROUND: The cytologic diagnosis of Small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL) often relies on finding a small lymphoid population with the characteristic immunoprofile by ancillary testing.

There are only a few reports of other processes identified with SLL/CLL.

The aim of this study was to review the fine needle aspiration (FNA) and touch prep (TP) diagnoses of SLL/CLL in order to identify any coincident entities.

MATERIALS AND METHODS: We retrospectively reviewed all FNA and TP cytology cases between January 2005 and May 2009 with a diagnosis of SLL/CLL to determine the presence of any coincident process.

Coincident entities were identified in nine cases (31%) and included seven (28%) neoplastic entities (Hodgkin lymphoma [HL], adenocarcinoma, squamous cell carcinoma, seminoma) and two (7%) non-neoplastic entities (infection and immunoglobulin containing cells).

Six cases (21%) suspicious for large cell transformation were also identified.

CONCLUSION: In our review of SLL/CLL, coincident entities were present in 31% of the cases and included a spectrum of non-neoplastic and neoplastic processes.

FC was the most frequently utilized ancillary test, but IHC provided important information by excluding a mantle cell lymphoma or confirming a coincident process.

[Title] Serum leptin levels are higher in females affected by frontotemporal lobar degeneration than Alzheimer's disease.

The adipocyte derived hormone leptin is known to play a foundamental role in food intake and energy balance.

To understand whether leptin could be involved in FTLD eating abnormalities, we measured serum leptin levels in 59 patients with FTLD compared with 25 with AD.

Serum leptin levels in patients with FTLD were comparable with those in patients with AD.

Nevertheless, females with FTLD showed significantly higher leptin levels compared with females with AD.

Hyperphagic FTLD females showed higher circulating leptin levels in comparison with those without eating abnormalities; no differences were found between males with FTLD with respect to serum leptin and food intake disturbances.

The present study showed a selective gender difference in leptin levels between females with FTLD and AD, which may suggest specific cognitive and behavioural networks need to be investigated.

[Title] Serum leptin levels are associated with cognitive function in older adults.

Recent work suggests that leptin, a circulating adipokinine hormone, might contribute to age-related cognitive decline.

The present study investigated the relationship between serum leptin levels and cognitive function in older adults.

Partial correlations adjusting for demographic and medical conditions showed that higher leptin levels were associated with poorer performance on Trail Making Test B (r = .46, p = .01).

These findings indicate that serum leptin levels are negatively associated with speeded executive function in older adults without significant neurological or psychiatric conditions.

[Title] Systemic stress increases serum leptin level.

BACKGROUND AND AIM: Leptin, the product of the obese (ob) gene, is a circulating peptide mainly synthesized by adipocytes.

Leptin inhibits food intake and decreases body weight.

A recent report has suggested that the gastric mucosa is also the source of leptin, and that the stomach leptin also contributes to the regulation of the serum leptin level.

The aim of the present study was to investigate the effect of water-immersion stress on serum, stomach and adipose tissue leptin levels to understand the relationship between stress and eating behavior.

The leptin level in the serum, gastric mucosa and adipose tissue was measured using ELISA system before and after the initiation of water-immersion stress.

RESULTS: The serum leptin level was significantly increased by water-immersion stress.

However, the gastric leptin level significantly decreased 6 and 9 h after the stress.

The adipose tissue leptin level significantly increased 3 h after the stress.

CONCLUSIONS: The results suggest that changes in serum leptin levels could be associated with stimulation of leptin secretion from the gastric mucosa and leptin production in the adipose tissue by systemic stress and that leptin might be regulated by stress-related events.

[Title] Serum leptin levels, skin leptin and leptin receptor expression in psoriasis.

Leptin, a peptide hormone secreted predominantly from adipose tissue, is involved in the regulation of energy intake and expenditure.

OBJECTIVES: To investigate the possible role of leptin in psoriasis pathogenesis.

Serum fasting leptin levels of the study group were examined by enzyme-linked immunosorbent assay.

Tissue leptin and leptin receptor expression of both patients and controls were investigated by immunohistochemistry.

RESULTS: Serum leptin levels, tissue leptin and leptin receptor expression were significantly higher in patients with severe psoriasis than patients with mild-moderate psoriasis and controls (P < 0.05).

Serum leptin levels showed a positive correlation with Psoriasis Area and Severity Index and involved body surface area in patients with psoriasis.

In addition, serum leptin levels, tissue leptin and leptin receptor expression showed a positive correlation with disease duration in patients with psoriasis (P < 0.01, r = 0.979; P < 0.01, r = 0.691; P < 0.01, r = 0.428, respectively).

CONCLUSIONS: We assume that leptin might serve as a marker of severity in psoriasis and also may be a pathogenetic cofactor contributing to chronicity of the disease.

In addition, drugs targeting the proinflammatory effects of leptin may be a new adjuvant therapeutic approach in psoriasis.

[Title] Serum leptin levels and malnutrition in patients with chronic renal failure.

OBJECTIVE: To investigate the correlation between serum leptin levels, body mass index, and triceps skin fold thickness, which are anthropometric measurements, as well as serum albumin levels in patients with chronic renal failure on hemodialysis.

Similarly, patients with diabetes mellitus, chronic pulmonary disorders, and hepatic cirrhosis or hepatitis B, hepatitis C carriers as well as those on active tuberculosis therapy were excluded.

The mean serum leptin level for males was 4.61 +/- 4.20 ngr/dl (0.1-18.7 ngr/dl), and for females, it was 52.06 +/- 61.67 ngr/dl (0.6-172.5 ngr/dl).

A positive correlation was observed between triceps skin fold thickness and leptin, both in the male group (r=0.478; p<0.05), and in the female group (r=0.876; p<0.05).

Body mass index and leptin were also correlated positively both in the male group (r=0.502; p<0.05) and in the female group (r=0.905; p<0.05).

No correlation was established between serum albumin levels and leptin.

Leptin did not correlate with other measured parameters CONCLUSION: Our study demonstrates that serum leptin levels positively correlated with body mass index and triceps skin fold thickness, which are malnutrition parameters.

Therefore, the leptin hormone may be utilized in obtaining preliminary information regarding malnutrition.
