**Do statins really cause diabetes? *A meta-analysis of major randomized controlled clinical trials***

Rahal et al conclude that statin therapy can slightly increase risk of incident diabetes in subjects with hypercholesterolemia. Fourteen studies were included in the analysis with a total of 94,943 participants. Of these, 2392 subjects developed incident diabetes in the statin and 2167 in the placebo groups during a 4-year follow-up. The odds ration (OR) of diabetes incidence with statin therapy was significantly higher as compared with the placebo group. There was an insignificant level of heterogeneity between the included trials. Subgroup analysis showed that only 2 statins namely, atorvastatin, and rosuvastatin were significantly associated.

**The role of platelet count, mean platelet volume, and the mean platelet volume/platelet count ratio in predicting postoperative vomiting in children after deep sedation**

Canpolat et al found that the platelet count (PLT), mean platelet volume (MPV), and MPV/PLT ratio may be used to predict postoperative vomiting (POV) in children. Fifty patients without POV (group 1) and 50 patients with POV (group 2) were retrospectively selected randomly from the records of 885 consecutive patients. Age, gender, duration of the operation, and preoperative hemogram findings were recorded.

**Primary experience of bariatric surgery in a newly established private obesity center**

Al-Shurafa et al discuss the outcomes of different types of bariatric surgeries in a single newly established private obesity center. A total of 79 patients were included. Based on the type of surgery, patients were divided into 3 groups: laparoscopic Roux-en-Y gastric bypass (RYGB), laparoscopic minigastric bypass (MGBP), and laparoscopic vertical sleeve gastrectomy (SG). After one year, RYGB and MGB patients lost more weight than SG patients. No mortality, or leak were reported and one patient had reoperation after revision laparoscopic RYGB for bleeding. There was one readmission, while 4 patients visited the emergency room for vomiting and dehydration (2 patients), anemia (one patient), and port site infection (one patient).

# CASE REPORT {#article-title-4}

**The superior gluteal artery perforator flap for reconstruction of sacral sores**

Chen et al show the experiences obtained from using the superior gluteal artery perforator (SGAP) flaps for reconstruction of sacral sores. A 47-year-old female patient and a 38-year-old man with sacral sores were treated. The size of the defects were approximately 5×6 cm2 and 8×9 cm2, the defects were repaired by SGAP flaps. The size of designed was SGAP flaps varied from 7×20 to 9×16 cm2. All flaps survived and healed primary, the texture, functions, and appearance of flaps were satisfactory, and also without region dysfunction of donor and recipient sites.
