Although bariatric surgery is a safe and effective procedure in the treatment of adolescent morbid obesity, long-term data is scarce regarding its nutritional and developmental complication in this growing population of patients.

Cancer is the second leading cause of death globally. piRNAs, which are a novel type of identified small noncoding RNA (ncRNA), play a crucial role in cancer genomics. In recent years, a relatively large number of studies have demonstrated that several piRNA are aberrantly expressed in various kinds of cancers including gastric cancer, bladder cancer, breast cancer, colorectal cancer and Lung cancer and may probably serve as a novel therapeutic target and biomarker for cancer treatment. The present review summarized current advances in our knowledge of the roles of piRNAs in cancer.

The goal of this study is to compare the response rate and the recurrence rate of available therapeutic modalities in the treatment of Idiopathic Granulomatous Mastitis (IGM). 374 patients with pathologically confirmed IGM, were included. They were subdivided into three levels of severity. Close observation had the best response rate with the lowest recurrence rate in mild to moderate cases. Severe cases were mostly treated by prednisolone or underwent surgery. The outcome of prednisolone use in severe cases was comparable to NSAIDs. Overall 9% were resistant to treatment and surgical intervention is still an option among them.
