To study the efficacy of extramembranous transfer of the tibialis posterior (posterior tibial) tendon for the treatment of drop foot deformity in children. ⋯ Extramembranous transfer of the tibialis posterior tendon is a quite successful method in retrieving active dorsiflexion of the foot in patients with drop foot deformity. It is a method which eliminates the need for orthosis and enhances the quality of life of patients.

The morbidity of unsuspected gallbladder carcinoma (UGC) has increased. This study was aimed to explore the factors which may influence the therapeutic strategies and prognosis of UCG. Additionally, long-term prognosis of laparoscopic and open surgeries of UGC was comparatively investigated. ⋯ Radical resection surgery is recommended in pT2 stage UGC. There is no difference for the long-term prognosis between laparoscopic surgery (cholecystectomy) and open surgery of UCG.

Leptin, an adipocyte-derived hormone, has a pivotal role in the regulation of body weight through acting on its specific leptin receptor (LEPR). The 223A/G polymorphism of the LEPR gene is one of the most common polymorphism in all populations. In this study, we aimed to investigate the impact of the 223A/G polymorphism of the LEPR gene on serum levels of leptin in type 2 diabetes mellitus (T2DM) in a sample of Iranian population. ⋯ The mean serum levels of leptin in T2DM patients were significantly higher than that of healthy control subjects; 22.90 ng/ml (95 % confidence interval [CI] = 20.79 - 25.23) vs. 8.70 ng/ml (95 % CI = 7.87 - 9.63). The genotypes (AA, AG, and GG) distributions of the 223A/G polymorphism were 55.5 %, 41 %, and 3.5 % in T2DM and 54.4 %, 42.2 %, and 3.4 % in healthy controls. The results showed no significant differences in the 223A/G LEPR genotype and allele frequencies between T2DM and control subjects (χ2 = 0.043, P = 0.979 and χ2 = 0.003, P = 0.957), respectively. In addition, the serum leptin levels were markedly higher in subjects with GG genotype than those with AG or GG genotype only in T2DM CONCLUSION: The 223A/G LEPR gene polymorphism is associated with markedly increased serum leptin levels in T2DM. However, no differences were determined in genotype and allele frequencies between T2DM patients and control subjects.

Iranian Registry of Clinical Trials (IRCT) commenced its activities as a member of WHO registry network on fourth of December 2008. We explored the progress it has made within its first four years both in terms of quantity of registrations as well as its timeliness. ⋯ IRCT has made an outstanding progress within four years from its establishment both in terms of quantity and timeliness. Registration movement has succeeded in getting the message across to the research community and clinical trial registration has now become an integral part of research sphere in Iran.

Botulism is a serious neuroparalytic disease caused by toxins of Clostridium botulinum. Botulinum toxin is produced under anaerobic conditions and is one of the most dangerous toxin in the world. Rapid diagnosis of botulism is very essential for successful therapy. In this study, we reviewed data of cases of botulism in Iran from April 2004 through March 2010. ⋯ Accurate and rapid diagnosis of botulism is very important because every case of botulism can be a public health emergency. During the study period, the median number of positive cases per year was 2.7 (range: one to18). Therefore, it is suggested that all clinicians are required to submit the collected samples from patients with botulism symptoms to the botulism reference laboratory for specific diagnosis and confirmation of botulism.
