Peritoneal transport characteristics and residual renal function require regular control and subsequent adjustment of the peritoneal dialysis (PD) prescription. Prescription models shall facilitate the prediction of the outcome of such adaptations for a given patient. In the present study, the prescription model implemented in the PatientOnLine software was validated in patients requiring a prescription change. This multicenter, international prospective cohort study with the aim to validate a PD prescription model included patients treated with continuous ambulatory peritoneal dialysis. Patients were examined with the peritoneal function test (PFT) to determine the outcome of their current prescription and the necessity for a prescription change. For these patients, a new prescription was modeled using the PatientOnLine software (Fresenius Medical Care, Bad Homburg, Germany). Two to four weeks after implementation of the new PD regimen, a second PFT was performed. The validation of the prescription model included 54 patients. Predicted and measured peritoneal Kt/V were 1.52 0.31 and 1.66 0.35, and total (peritoneal + renal) Kt/V values were 1.96 0.48 and 2.06 0.44, respectively. Predicted and measured peritoneal creatinine clearances were 42.9 8.6 and 43.0 8.8 L/1.73 m(2)/week and total creatinine clearances were 65.3 26.0 and 63.3 21.8 L/1.73 m(2) /week, respectively. The analysis revealed a Pearsons correlation coefficient for peritoneal Kt/V of 0.911 and Lins concordance coefficient of 0.829. The value of both coefficients was 0.853 for peritoneal creatinine clearance. Predicted and measured daily net ultrafiltration was 0.77 0.49 and 1.16 0.63 L/24 h, respectively. Pearsons correlation and Lins concordance coefficient were 0.518 and 0.402, respectively. Predicted and measured peritoneal glucose absorption was 125.8 38.8 and 79.9 30.7 g/24 h, respectively, and Pearsons correlation and Lins concordance coefficient were 0.914 and 0.477, respectively. With good predictability of peritoneal Kt/V and creatinine clearance, the present model provides support for individual dialysis prescription in clinical practice. Peritoneal glucose absorption and ultrafiltration are less predictable and are likely to be influenced by additional clinical factors to be taken into consideration.

Background: Today, in the management of pancreas cancers, achieving an R0 resection is one of the most powerful independent predictors of long-term survival. The aim of this study is to assess the clinical significance of intraoperative frozen section analysis of the pancreatic surgical margin for pancreatic cancer during pancreaticoduodemectomy. Material and Methods: We conducted a retrospective analysis of prospectively collected data of 37 patients who were operated for pancreatic head cancer and who were evaluated for surgical margin by frozen section analysis intraoperatively, between September 2013 and August 2014 in our center. The intraoperative biopsy reports were compared with final pathological reports. Results: The mean age of the patients was 64.55(19-82) years (range), the mean tumor size was 3.96(1.16-6.25) cm (range) and the mean harvested lymph node number was 18.52(9-45) (range). In the intraoperative frozen section, one patient was positive for surgical margin (%2.7) who underwent total or complementary pancreatectomy. Conclusion: To secure a tumor-free margin by frozen section, intraoperatively, may increase R0 resection rate in pancreas cancers. The preoperative estimation of tumor margin by endoscopic ultrasonography, computerized tomography or magnetic resonance imaging mostly correlate with intraoperative findings, however in suspected cases intraoperative frozen section for margin determination should be performed.

The objective of this study was to determine the transmitted drug resistance mutations (TDRMs) in newly diagnosed HIV-1 positive patients in Turkey.The study was carried out between 2009 and 2014 and antiretroviral nave 774 HIV-1 infected patients from 19 Infectious Diseases and Clinical Microbiology Departments in Turkey were included; gender: 664 (86%) male, median age: 37 (range; 1-77), median CD4+T-cell: 360 (range; 1-1320) count/mm(3), median HIV-RNA load: 2.10+E6 (range; 4.2+E2-7.41+E8) IU/mL. HIV-1 drug resistance mutations were detected by population based sequencing of the reverse transcriptase (codon 41-238) and protease (codon 1-99) domains of pol gene of HIV-1, and analyzed according to the criteria by the World Health Organization 2009 list of surveillance drug resistance mutations .The patients had TDRMs to NRTIs (K65R, M184V), NNRTIs (K101E, K103N/S, G190A/E/S, Y181I/C, Y188H/L) and PIs (M46L, I54V, L76V, V82L/T, N83D, I84V, L90M). The prevalence of overall TDRMs was 6.7% (52/774). Resistance mutations were found to be 0.7% (6/774), 4.1% (32/774) and 2.1% (17/774) to NRTIs, NNRTIs and PIs drug groups, respectively. Three patients had NRTIs+NNRTs resistance mutations (M184V+K103N) as multi-class drug resistance. However, thymidine analogue resistance mutations (TAMs) determined two distinct genotypic profiles in the HIV-1 reverse transcriptase: TAM1: M41L, L210W and T215Y, and TAM2: D67N, K70R, K219E/Q, and T215F. The prevalence of TAM1 and TAM2 were 7.7% (60/774) and 4.3% (34/774), respectively.The TDRMs prevalence of antiretroviral nave HIV-1 infected patients may be suggested current situation of Turkey. These long-term and large-scale results show that the resistance testing must be an integral part of the management of HIV infection in Turkey.

This study aimed to evaluate the efficacy, cost, and effects of anti-D immunoglobulin (anti-D Ig), methylprednisolone, or intravenous immunoglobulin (IVIG) therapy on the development of chronic disease in children who are Rh-positive with diagnosed immune thrombocytopenic purpura (ITP). Children with newly diagnosed ITP and platelet count <20,000/mm3 were prospectively randomized to treatment with anti-D Ig (50 μg/kg), methylprednisolone (2 mg/kg/day), or IVIG (0.4 g/kg/day, 5 days). Sixty children with a mean age of 6.7 years were divided into three equal groups. No difference was observed between platelet counts before treatment and on day 3 of treatment. However, platelet counts at day 7 were lower in the methylprednisolone group than in the IVIG group (P = 0.03). In the anti-D Ig group, hemoglobin and hematocrit levels were significantly lower at the end of treatment (P < 0.05). Chronic ITP developed in 30 % of the anti-D Ig group, 35 % of the methylprednisolone group, and 25 % of the IVIG group, but no significant difference was noted among the groups. The cost analysis revealed that the mean cost of IVIG was 7.4 times higher than anti-D Ig and 10.9 times higher than methylprednisolone. In the treatment of ITP in childhood, one 50 μg/kg dose of anti-D Ig has similar effects to IVIG and methylprednisolone. Among patients who were treated with anti-D Ig, serious anemia was not observed, and the cost of treatment was less than that of IVIG treatment. © 2012 Springer Science+Business Media, LLC.

Insulin resistance (IR) and pancreatic β-cell dysfunction are usual comorbidities in polycystic ovary syndrome (PCOS). Vascular endothelial growth factor (VEGF) is known to play an important role in the pathogenesis of PCOS. This study examined firstly the possible association of common +405 G/C, -460 T/C and -2578 A/C polymorphisms of VEGF gene with fasting glucose, fasting insulin and the indices of IR [glucose/insulin ratio (GIR), homoeostasis model assessment (HOMA) and quantitative insulin sensitivity check index (QUICKI)] in 137 patients with PCOS. None of the studied polymorphisms were found to affect IR indices significantly. However, there was a trend towards higher HOMA in +405 G and -460 T allele carriers in comparison with homozygotes +405 CC and -460 CC, respectively. With regard to -2578 A/C polymorphism, although not significant, in -2578 C carriers HOMA was lower, and GIR was higher in comparison with -2578 AA genotype. Alteration of QUICKI between genotypes was minimal and varied from 4% to 7%. Because of the relatively small sample size, more studies with greater number of cases are necessary to confirm our observations before any statement can be made about the relationship between VEGF gene polymorphism and IR parameters in PCOS. © 2010 Blackwell Publishing Ltd.

Objective: To evaluate retrospectively in patients with Crohn's disease (CD) if magnetic resonance (MR) motility alterations correlate with CD typical lesions leading to an increased detection rate. Methods: Forty patients with histologically proven CD underwent MR enterography (MRE), including coronal cine sequences (cine MRE), in addition to the standard CD MR protocol. Two blinded readings were performed with and without cine MRE. Locations presenting motility alterations on the cine sequences were analysed on standard MRE for CD-related lesions. This was compared with a second reading using the standard clinical MRE protocol alone. Results: The number of lesions localised by cine MRE and identified on standard MRE compared with standard MRE alone were 35/24 for wall thickening (p=0.002), 24/20 for stenoses (p=0.05), 17/11 for wall layering (p=0.02), 5/3 for mucosal ulcers (p=0.02) and 21/17 for the comb sign (p=0.05). Overall, cine MRE detected 35 more CD-specific findings than standard MRE alone (124/89; p = 0.007) and significantly more patients with CD-relevant MR findings (34/28; p=0.03). Conclusion: CD lesions seem to be associated with motility changes and this leads to an increased lesion detection rate compared with standard-MRE imaging alone. © European Society of Radiology 2010.

As with other types of endometriosis in the intestinal tract, endometriosis of the appendix is generally asymptomatic and is usually discovered incidentally during laparotomy in patients with pelvic endometriosis. When it presents with symptoms they are difficult to differentiate from acute appendicitis. Appendiceal endometriosis may not only cause symptoms of acute appendicitis, but may also present as cyclic and chronic right lower quadrant pain, melena, lower intestinal haemorrhage and caecal intussusception. We report a case of appendiceal endometriosis clinically presenting as acute appendicitis, where the definitive diagnosis was established by histopathological examination of the appendix.

Background/aims: We aimed to identify the genetic factors associated with increased tendency toward autoimmune hepatitis, a chronic and progressive inflammatory condition. Methods: A total of 32 children diagnosed with autoimmune hepatitis were included in the present study, and 160 healthy adult blood donors served as controls. In both groups, HLA phenotypes were examined (HLA-A, B, C, DR, DQ) and compared. In addition, the association between the type of autoimmune hepatitis and HLA status was explored. Results: Compared to controls, patients with autoimmune hepatitis had increased frequencies of the following class 1 HLA antigens: A24.9 (28% vs. 9%, p=0.007), A26 (25% vs. 3%, p<0.001), A32 (34% vs. 4%, p<0.001), B38 (9% vs. 0.6%, p=0.015), and B51 (16% vs. 0%, p<0.001). Among class II HLA antigens, DRB1*04 (22% vs. 0%, p<0.001), DRB1*07 (9% vs. 0%, p=0.004), DRB1*11 (12% vs. 0%, p=0.001), DRB1*15 (25% vs. 0%, p<0.001), DRB1*14 (31% vs. 0%, p=0.001), and DR11.5 (9% vs. 0%, p=0.004) were more frequent in patients compared to controls. Type 1 autoimmune hepatitis was associated with high frequencies of A24.9, A26, A32, and DRB1*15, whereas type 2 autoimmune hepatitis was associated with high frequencies of A26, B51, B38, and DRB1*11. On the other hand, frequencies of A32 and DRB1*04 were high among patients with unclassified autoimmune hepatitis. Conclusions: There seem to be associations between certain HLA antigens and susceptibility to autoimmune hepatitis, but variations among different geographical locations suggest a role for environmental factors.
