Objective: To determine the rate of distal symmetrical polyneuropathy (DSP) in patients with type 2 diabetes mellitus, to evaluate the role of history, neurological examination and the electrodiagnostic methods in the diagnosis of DSP, and to determine the association between electromyography-supported neuropathy (ESN), neuropathic complaints (NCs) and risk factors. Subjects and Methods: A total of 191 type 2 DM patients (109 female, 82 male; mean age 58.7 ± 10 years) were recruited. The NCs were recorded. All patients had electromyographic (EMG) examinations. The relationship between ESN, NCs and risk factors were evaluated. Results: Of the 191 patients, 83 (43.5%) had DSP on EMG examinations and 92 (48.2%) patients suffered from NCs. Among the ESN patients, a significant relationship existed with HbA1_c level, illness duration, smoking, male gender or insulin usage (p < 0.05) but not with age, hypertension, hypercholesterolemia or hypertriglyceridemia. The frequency of NCs was higher in patients with ESN. There was also a significant association between NCs and ESN (p < 0.05). The presence of NCs was not related to age, gender, smoking, hypertension, hypercholesterolemia and hypertriglyceridemia (p > 0.05) but NCs were correlated to HbA1_c level, illness duration and insulin usage (p < 0.05). Conclusion: Our data show that a strong association exists between the presence of DSP and illness duration, HbA1_c, smoking, thereby indicating that cessation of smoking and near normal glycemic control would be additional precautions to delay the beginning or progression of polyneuropathy.

The treatment of caustic esophageal strictures is a challenging topic. Although traditional therapies have limited efficacy, most of these patients eventually require surgery. Biodegradable (BD) stents are newly designed stents for benign conditions. This is a retrospective case series of seven patients with caustic esophageal stricture. BD esophageal stents were inserted for palliation of dysphagia. The position of the stent was checked at 1, 4, 8, 12 16, 20, and 24 weeks and at the end of follow-up period. The follow-up period was 60 ± 23 (36-102) weeks. Complete dissolution of the stent occurred at 16 ± 4 (12-20) weeks. Three patients had partial/complete relief of dysphagia. The remaining four patients experienced tissue hyperplasia at the edges of the stent and required serial dilations. At the end of follow-up, all patients had partial or complete relief of dysphagia. Although BD stents have some efficiency, tissue hyperplasia is the main limiting factor. Further randomized trials are needed to determine efficiency of BD stents for caustic damage.

AimTo evaluate the main platelet volume (MPV) as a severity marker in patients with primary biliary cirrhosis (PBC).Materials and methodsThirty-nine patients with biopsy-proven and as yet untreated PBC followed between January 2008 and January 2015 were included in this study. Liver biopsies were categorized as early stage (stage 1 and 2 according to Scheuer’s histological stage) and late stage (Scheuer’s stage 3 and 4). As part of the routine evaluation, all PBC patients had their full blood count and biochemistry profile determined, where MPV, white blood cell count, hemoglobin, platelet count, red cell distribution width (RDW), alanine aminotransferase, aspartate aminotransferase (AST), gamma glutamyl transferase, alkaline phosphatase, and total bilirubin values were evaluated. Both groups were compared in terms of the RDW/platelet ratio, the AST platelet ratio index, and the neutrophil lymphocyte ratio.ResultsEighteen patients had early-stage disease (46.2%), whereas 21 PBC patients had late-stage disease (53.8%). There were no differences between groups in terms of routine hematological parameters (white blood cell count, platelet count, hemoglobin, RDW) or biochemical parameters (alanine aminotransferase, AST, gamma glutamyl transferase, alkaline phosphatase, total bilirubin, albumin) (P>0.05). Similarly, there were no differences in AST platelet ratio index, RDW/platelet ratio, or neutrophil lymphocyte ratio values between groups (P values 0.08, 0.19, and 0.14, respectively). The MPV and direct bilirubin were significantly higher in the advanced stage group compared with the early-stage group (11.08 vs. 9.73 fl, respectively, P=0.01 and 0.44 vs. 0.28 mg/dl, respectively, P=0.03). The area under the curve, cut-off value, sensitivity, and specificity of MPV and direct bilirubin for detecting advanced stage were 0.721, 10.3, 71%, and 66%, respectively, and 0.698, 0.23, 71%, and 66%, respectively.ConclusionMPV can be used as a noninvasive, simple, and effective parameter in patients with PBC to predict histological severity of the disease.

Fecal elastase-1 levels was significantly lower in group 1 compared to group 2 (319.76±45.7 vs 549.31±69.4, respectively, p=0.003). Proportion of patients with EPI was significantly higher in group 1 than group 2 (35.5% vs 12% p=0.042). There were no significant differences in terms of severity or the anatomic distribution of PS in patients with PS with EPI based on MRI (p=0.052, p=0.198, p=0.405) Conclusion: Current study demonstrates that PS can cause EPI.
