Neuroendocrine neoplasms of the gastroenteropancreatic system are classified according to the WHO classification system 2010 into neuroendocrine tumors (NET) and neuroendocrine carcinomas (NEC). The proliferation index Ki-67 and the grading of NETs is essential for the prognosis and therapy plan. Also NET tumor biology and therapeutic options may differ depending on the primary NET tumor location. ⋯ This manuscript reviews the current role of biotherapy with somatostatin analogues and interferon-alpha for symptom and tumor control. In addition conventional chemotherapy regimens and novel molecular targeted therapeutic options, such as sunitinib or everolimus in NET of the pancreas are reviewed. Possible therapeutic algorithms are discussed.

Vaccines for post-exposure prophylaxis against varicella (chickenpox) in children and adults.
Live attenuated varicella vaccines for the prevention of varicella (chickenpox) has been demonstrated both in randomised controlled trials (RCTs) and in population-based immunisation programmes in countries such as the United States. However, many countries do not routinely immunise children against varicella, and exposures continue to occur. Although the disease is often mild, complications such as secondary bacterial infection, pneumonitis and encephalitis occur in about 1% of cases, usually leading to hospitalisation. The use of varicella vaccine in persons who have recently been exposed to the varicella zoster virus has been studied as a form of post-exposure prophylaxis (PEP). ⋯ These small trials suggest varicella vaccine administered within three days to children following household contact with a varicella case reduces infection rates and severity of cases. No RCTs for adolescents or adults were identified. However safety was not adequately addressed.

Premature ejaculation (PE) is a very common sexual dysfunction among patients, and with varying prevalence estimates ranging from 3% to 20%. Although psychological issues are present in most patients with premature PE, as a cause or as a consequence, research on the effects of psychological approaches for PE has in general not been controlled or randomised and is lacking in long-term follow up. ⋯ Overall, there is weak and inconsistent evidence regarding the effectiveness of psychological interventions for the treatment of premature ejaculation. Three of the four included randomised controlled studies of psychotherapy for PE reported our primary outcome (Improvement in IELT), and the majority have a small sample size. The early success reports (97.8%) of Masters and Johnson could not be replicated. One study found a significant improvement from baseline in the duration of intercourse, sexual satisfaction and sexual function with a new functional-sexological treatment and behavior therapy compared to waiting list. One study showed that the combination of chlorpromazine and BT was superior to chlorpromazine alone. Randomised trials with larger group samples are still needed to further confirm or deny the current available evidence for psychological interventions for treating PE.
