RESUMEN
Primary cutaneous posttransplant lymphoproliferative disorders (PTLD) are rare. This retrospective, multicenter study of 35 cases aimed to better describe this entity. Cases were (re)-classified according to the WHO-EORTC or the WHO 2008 classifications of lymphomas. Median interval between first transplantation and diagnosis was 85 months. Fifty-seven percent of patients had a kidney transplant. Twenty-four cases (68.6%) were classified as primary cutaneous T cell lymphoma (CTCL) and 11 (31.4%) as primary cutaneous B cell PTLD. Mycosis fungoides (MF) was the most common (50%) CTCL subtype. Ten (90.9%) cutaneous B cell PTLD cases were classified as EBV-associated B cell lymphoproliferations (including one plasmablastic lymphoma and one lymphomatoid granulomatosis) and one as diffuse large B cell lymphoma, other, that was EBV-negative. Sixteen (45.7%) patients died after a median follow-up of 19.5 months (11 [68.8%] with CTCL [6 of whom had CD30(+) lymphoproliferative disorders (LPD)] and 5 [31.2%] with cutaneous B cell PTLD. Median survival times for all patients, CTCL and cutaneous B cell PTLD subgroups were 93, 93, and 112 months, respectively. Survival rates for MF were higher than those for CD30(+) LPD. The spectrum of primary CTCL in organ transplant recipients (OTR) is similar to that in the general population. The prognosis of posttransplant primary cutaneous CD30(+) LPD is worse than posttransplant MF and than its counterpart in the immunocompetent population. EBV-associated cutaneous B cell LPD predominates in OTR.

BACKGROUND AND AIM: Helicobacter pylori infection is common world-wide and has been linked to development of gastric and duodenal ulcers, gastric adenocarcinoma, and gastric lymphoma. However, antimicrobial resistance has decreased H. pylori eradication rates worldwide. This study aimed to evaluate the effect of -bacterial load on eradication rate. METHOD: This prospective study included 237 consecutive patients who presented to our institution with dyspeptic symptoms and underwent both upper endoscopy and urea breath tests (UBT). The patients were divided into three equal sized groups according to their UBT values. All subjects received a standard triple eradication regimen, followed by a bismuth- based quadruple eradication regimen if triple eradication was not successful. The three groups were compared with respect to age, endoscopic findings, sex, and eradication rates. RESULTS: Our results were consistent with those of previous studiesâ: higher UBT values were associated with failure of standard 14-day triple treatment (pâ<â0.05). However, in patients who received a quadruple eradication regimen, differences between groups were not significant (pâ=â0.434). There was no relationship between UBT values and gastric pathologies (pâ=â0.751). Age and sex also did not differ significantly between groups (pâ=â0.061). CONCLUSIONS: Our study and others have found that high bacterial loads are negatively associated with achievement of eradication with triple treatment. However, differences between groups were not significant in patients who received a quadruple eradication regimen. Comparisons of treatment results according to bacterial density may be informative. The importance of H. pylori density should be further evaluated with new treatment protocols.

AIM: Atrial fibrillation is the most common arrhythmia and complication following coronary bypass surgery. Besides well-known risk factors, inflammatory parameters have gained popularity assessing the risk of postoperative atrial fibrillation. In this study, we aimed to document the relation between neutrophil/lymphocyte ratio and postoperative atrial fibrillation. METHODS: Between January 2011 and June 2012, 523 patients on normal sinus rhythm, undergoing elective on-pump coronary bypass operations were prospectively followed up for occurrence of postoperative atrial fibrillation. Total and differential white blood cell counts were made immediately before the operation and on postoperative day 2. Neutrophil/lymphocyte ratio was calculated from these measured values. RESULTS: Ninety-one (17.4%) patients developed postoperative atrial fibrillation The mean age of the patients maintaining normal sinus rhythm was lower compared to ones with atrial fibrillation (60.76±9.59 vs. 65.44±8.63, P<0.001). Preoperative and postoperative total and differential white blood cell counts did not have any effect on occurrence of atrial fibrillation. There were not statistically significant differences between normal sinus rhythm and atrial fibrillation groups when preoperative and postoperative neutrophil/lymphocyte ratios were considered (2.90±2.11 vs. 3.02±2.30, P=0.619; 10.07±21.97 vs. 9.34±6.73, P=0.752, respectively). CONCLUSION: Neutrophil/lymphocyte ratio was not found to be a predictor for new onset atrial fibrillation following coronary bypass surgery.

BACKGROUND: Patients with end-stage renal disease (ESRD) experience erectile dysfunction (ED). Although it is a benign disorder, ED is related to physical and psychosocial health, and it has a significant impact on the quality of life (QOL). The objective of the present study was to investigate the effects of different renal replacement therapies on ED. METHODS: A total of 100 ESRD patients and 50 healthy men were recruited to the present cross-sectional study. The study was consisted of 53 renal transplantation (RT; group I; mean age, 39.01 ± 7.68 years; mean duration of follow-up, 97.72 ± 10.35 months) and 47 hemodialysis (HD) patients (group II; mean age, 38.72 ± 9.12 years; mean duration of follow-up, 89.13 ± 8.65 months). The control group consisted of 50 healthy men (group III; mean age 39.77 ± 8.51 years). Demographic data and laboratory values were obtained. All groups were evaluated with the following scales: International Index of Erectile Function (IIEF)-5 and Short Form (SF)-36 questionnaires, and Beck Depression Inventory (BDI). The patients whose IIEF score were ≤ 21 were accepted as having ED. RESULTS: The mean age of these groups were similar (P > .05). Total IIEF-5 scores of men in groups I, II, and III were 19.5 ± 4.5, 16.4 ± 5.9, and 22.5 ± 3.4, respectively. The mean total IIEF-5 score of control group was higher than those of groups I and II (P < .001). Posttransplant group mean total IIEF-5 score was also higher than the HD group (P < .05). Groups I and II significantly differed from control group in terms of presence of ED (IIEF score ≤ 21: Group I, n = 28 [52.8%]; group II, n = 29 [61.7%]; and group III, n = 12 [%24], respectively [P < .001]), whereas there was no difference between groups I and II. In the logistic regression analysis (variables included age, BDI, and renal replacement therapy [HD and transplantation]), ED was independently associated with age (odds ratio [OR], 1.1; 95% confidence interval [CI], 1.05-1.2), BDI (OR, 1.1; 95% CI, 1.01-1.13). Additionally, ED was not associated with renal replacement therapy (OR, 1.46; 95% CI, 0.60-3.57). Physiologic health domain of SF-36 was significantly better in healthy controls (P < .001). Patient groups were similar in terms of BDI score (P > .05). ED score was negatively correlated with BDI (r = -0.368; P < .001), and positively correlated with SF-36 (r = 0.495; P < .001) in all patient groups. CONCLUSION: Patients with ESRD had significantly lower sexual function and lower QOL scores than the healthy control men. Notably, the mode of renal replacement therapy had no impact on male sexual function.

Diagnosis of active tuberculosis (TB) remains a challenge. In this a preliminary proof-of-concept study seeking to determine the feasibility of using cells from induced sputum for the immunodiagnosis of pulmonary TB (PTB) in smear-positive cases, a total of 75 subjects with PTB (n = 31) and healthy controls (n = 44) underwent the blood T-SPOT(R).TB test. T-SPOT.TB in induced sputum samples was performed in 29 of 31 TB and 14/44 healthy subjects. Induced sputum T-SPOT.TB results were indeterminate in 72.6% of TB and 100% of healthy subjects. The T-SPOT.TB test in induced sputum samples does not seem a feasible method for diagnosing PTB and needs improvement.
