To report demographic and injury characteristics of children admitted to burn centers with injuries from suspected child abuse and to assess mortality risk and length of stay compared with patients whose injuries were labeled accidental. ⋯ Compared with children with accidental burn injuries who had similar demographic and injury characteristics, children admitted to burn centers with suspected abuse were at greater risk of mortality and required longer intensive care and total hospital stays.

Research evaluating fatigue-induced skills decline has focused on acute sleep deprivation rather than the effects of circadian desynchronization associated with multiple shifts. As a result, the number of consecutive night shifts that residents can safely be on duty without detrimental effects to their technical skills remains unknown. A prospective observational cohort study was conducted to assess the impact of 7 successive night shifts on the technical surgical performance of junior residents. ⋯ Newly acquired technical surgical skills deteriorate maximally after the first night shift, emphasizing the importance of adequate preparation for night rotas. Performance improvements across successive shifts may be due to ongoing learning or adaptation to chronic fatigue. Further research should focus on assessments of both technical procedural skills and cognitive abilities to determine the rotas that best minimize errors and maximize patient safety.

Randomized Controlled Trial Comparative Study
Weight loss, appetite suppression, and changes in fasting and postprandial ghrelin and peptide-YY levels after Roux-en-Y gastric bypass and sleeve gastrectomy: a prospective, double blind study.
Bariatric surgery is currently the most effective treatment in morbidly obese patients, leading to durable weight loss. ⋯ PYY levels increased similarly after either procedure. The markedly reduced ghrelin levels in addition to increased PYY levels after LSG, are associated with greater appetite suppression and excess weight loss compared with LRYGBP.

Primary hyperparathyroidism (HPT) in multiple endocrine neoplasia type 1 (MEN1) patients with Zollinger-Ellison syndrome (ZES) is caused by parathyroid hyperplasia. Surgery for parathyroid hyperplasia is tricky and difficult. Long-term outcome in ZES/MEN1/HPT is not well known. ⋯ HPT/MEN1/ZES is a severe form of parathyroid hyperplasia with a high rate of nephrolithiasis, persistent and recurrent HPT. Surgery to correct the hypercalcemia significantly ameliorates the ZES. Removal of less than 3.5 glands has an unacceptably high incidence of persistent HPT (42%), whereas 4-gland resection and transplant has a high rate of permanent hypoparathyroidism (22%). More than 3-gland resection has a longer disease-free interval. The surgical procedure of choice for patients with HPT/MEN1/ZES is 3.5-gland parathyroidectomy. Careful long-term follow-up is necessary as a significant proportion will develop recurrent HPT.

Comparative Study
Combined portal vein embolization and neoadjuvant chemotherapy as a treatment strategy for resectable hepatic colorectal metastases.
The objectives of this study are 1) to determine whether the future liver remnant will grow after portal vein embolization (PVE) in patients with colon cancer on concurrent chemotherapy and 2) to determine whether recovery after extended hepatectomy is improved after PVE. ⋯ Liver growth occurs after PVE even when cytotoxic chemotherapy is administered. No major complications occurred with PVE. Patients requiring major hepatic resection should be considered for PVE during neoadjuvant chemotherapy to improve subsequent recovery after resection.
