Review Meta AnalysisDepot pipotiazine palmitate and undecylenate for schizophrenia.
Antipsychotic drugs are usually given orally but compliance may be problematic. The development of depot injections in the 1960s gave rise to their extensive use as a means of long-term maintenance treatment. Pipotiazine palmitate is a depot from the phenothiazine family of antipsychotic drugs. ⋯ Although well-conducted and reported randomised trials are still needed to fully inform practice (no trial data exists reporting hospital and services outcomes, satisfaction with care and economics) pipotiazine palmitate is a viable choice for both clinician and recipient of care.

Pulmonary Hypertension (PH) can be either of unknown aetiology (primary pulmonary hypertension (PPH)) or due to a known underlying cause (secondary pulmonary hypertension (SPH). Pulmonary arteriolar vasoconstriction is considered to be an important characteristic of PH. Therapies which aim to vasodilate are used to treat pulmonary hypertension. ⋯ The validity of the observed effects is undermined by small participant numbers and inadequate exploration of the different disease etiologies. The effects on long term outcome such as NYHA functional class, symptoms, mortality and exercise capacity require further validation. More studies of adequate size are required before the long term effects of sildenafil on clinically important outcomes can be established.

Review Meta AnalysisReplacement of estrogens and progestins to prevent morbidity and mortality in preterm infants.
A potential therapeutic effect of sex steroids on premature infants has been proposed from animal data and observational studies in humans. Purported benefits include reduction in chronic lung disease, improved bone density and improved neurodevelopmental outcome. ⋯ The one small randomised controlled trial demonstrated neither evidence of benefit or harm related to the replacement of estradiol and progesterone in preterm infants less than 30 weeks gestation. A properly powered randomised controlled trial is required to determine whether or not administration of estradiol or progesterone, either alone or in combination, and at varying doses, confers any clinically significant benefits, or poses any risk, to the preterm infant.

Review Meta AnalysisLaparoscopic versus open surgery for suspected appendicitis.
Laparoscopic surgery for acute appendicitis has been proposed to have advantages over conventional surgery. ⋯ In those clinical settings where surgical expertise and equipment are available and affordable, diagnostic laparoscopy and LA (either in combination or separately) seem to have various advantages over OA. Some of the clinical effects of LA, however, are small and of limited clinical relevance. In spite of the mediocre quality of the available research data, we would generally recommend to use laparoscopy and LA in patients with suspected appendicitis unless laparoscopy itself is contraindicated or not feasible. Especially young female, obese, and employed patients seem to benefit from LA.

ReviewPhysical methods for preventing deep vein thrombosis in stroke.
Deep vein thrombosis (DVT) and resulting pulmonary embolism (PE) are uncommon but important complications of stroke. There is good evidence that anticoagulants can reduce the risk of DVT and PE after stroke, but this benefit is offset by a small but definite risk of serious haemorrhages. Physical methods to prevent DVT and PE (such as compression stockings applied to the legs) are not associated with any bleeding risk and are effective in some categories of medical and surgical patients. We sought to assess their effects in stroke patients. ⋯ There is insufficient evidence from randomised trials to support the routine use of physical methods for preventing DVT in acute stroke.
