According to existing articles we may conclude that there is no difference between the two techniques regarding the periodontal outcomes and aesthetic appearance. The surgical procedure is shorter in the open exposure group and the amount of postoperative pain during the first day is similar between the open and closed surgical exposure patients. However, these conclusions are based on two single trials with high level of evidence, while the rest of the studies present high risk of bias.

Autoimmune hepatitis is a rare disease with unclear pathogenesis. Several viruses have been proposed to act as triggering agents for the inflammatory process of the disease; however, HIV has only very rarely been reported to be associated. We report a case of a patient with autoimmune hepatitis and HIV infection. The possible pathogenetic mechanism is discussed. Antiretroviral treatment led to normalization of liver biochemistry, supporting the hypothesis of HIV induced autoimmune hepatitis.

The synchronous occurrence of gastrointestinal stromal tumour (GIST) in the stomach and early gastric cancer is uncommon, with only a few previous reports. In particular, the collision of GIST and early gastric cancer in a patient with idiopathic thrombocytopenic purpura (ITP) has never been reported. We present the case of a 78-year-old male patient with ITP who was diagnosed with a synchronous development of GIST and early gastric cancer of the stomach. He underwent an elective subtotal gastrectomy with splenectomy. We discuss whether the development of GIST in the stomach in concert with early gastric cancer is an incidental coexistence or involve the same carcinogenic agents. Furthermore, it is not known whether or not such a situation is connected with ITP. To our knowledge this is the second report of a small GIST concomitant with an early gastric cancer and the first one in a patient with ITP.

Intracoronary delivery of CDCs attenuates myocardial inflammation, T-cell infiltration, and fibrosis while preventing myocarditis-induced systolic dysfunction and adverse remodeling in rats with experimental autoimmune myocarditis.
