Iron deficiency is the most common cause of anaemia in pregnancy worldwide. Iron treatment can be given by mouth, intramuscular or intravenous injection. Alternatively, blood transfusions and recombinant erythropoietin are also used. ⋯ This review provides inconclusive evidence on the effects of treating iron deficiency anaemia in pregnancy due to the shortage of good quality trials.

ReviewStapled versus handsewn methods for colorectal anastomosis surgery.
Randomized controlled trials comparing stapled with handsewn colorectal anastomosis have not shown either technique to be superior, perhaps because individual studies lacked statistical power. A systematic review, with pooled analysis of results, might provide a more definitive answer. ⋯ The evidence found was insufficient to demonstrate any superiority of stapled over handsewn techniques in colorectal anastomosis, regardless of the level of anastomosis.

ReviewDiuretic therapy for newborn infants with posthemorrhagic ventricular dilatation.
Intraventricular hemorrhage remains a serious complication of premature birth and post hemorrhagic hydrocephalus still has no satisfactory treatment. Acetazolamide and furosemide, which both reduce the production of cerebrospinal fluid, have been suggested as non-invasive therapies to reduce hydrocephalus and the need for ventriculo-peritoneal (V-P) shunting. ⋯ Acetazolamide and furosemide therapy is neither effective nor safe in treating post hemorrhagic ventricular dilatation. Acetazolamide and furosemide cannot be recommended as therapy for post hemorrhagic hydrocephalus.

ReviewChinese medicinal herbs for asymptomatic carriers of hepatitis B virus infection.
About 350 million people are chronically infected carriers of hepatitis B virus and are at a higher risk of serious illness and death from cirrhosis of the liver and liver cancer. Chinese medicinal herbs have been used widely for more than 2000 years to treat chronic liver disease. ⋯ Based on one low quality trial, the medicinal herb 'Jianpi Wenshen recipe' may have an antiviral activity in asymptomatic carriers of hepatitis B virus. However, rigorous randomised, double-blind, placebo-controlled trials are needed before herbs should be used for this condition.

Obstructive sleep apnoeas are due to transient closure of the upper airway during sleep and merge into hypopnoeas in which the airway narrows, but some airflow continues. They are due to the forces compressing the airway overcoming those which stabilise its patency. The commonest association is obesity in which fatty tissue is deposited around the airway. Exercise has been recommended as a method of losing weight, but other techniques which achieve this are also thought to improve symptoms due to sleep apnoeas. Sleep hygiene may alter the sleep structure and the control of the upper airway during sleep and thus promote its patency. ⋯ There is a need for randomised controlled trials of these commonly used treatments in obstructive sleep apnoeas. These should identify which sub groups of patients with sleep apnoeas benefit most from each type of treatment and they should have clear and standardised outcome measures.
