ReviewProphylactic vitamin K for vitamin K deficiency bleeding in neonates.
Vitamin K deficiency can cause bleeding in an infant in the first weeks of life. This is known as Hemorrhagic Disease of the Newborn (HDN). HDN is divided into three categories: early, classic and late HDN. Early HDN occurs within 24 hours post partum and falls outside the scope of this review. Classic HDN occurs on days one to seven; common bleeding sites are gastrointestinal, cutaneous, nasal and from a circumcision. Late HDN occurs from week 2-12; the most common bleeding sites are intracranial, cutaneous, and gastrointestinal. Vitamin K is commonly given prophylactically after birth for the prevention of HDN, but the preferred route is uncertain. ⋯ A single dose (1.0 mg) of intramuscular vitamin K after birth is effective in the prevention of classic HDN. Either intramuscular or oral (1.0 mg) vitamin K prophylaxis improves biochemical indices of coagulation status at 1-7 days. Neither intramuscular nor oral vitamin K has been tested in randomized trials with respect to effect on late HDN. Oral vitamin K, either single or multiple dose, has not been tested in randomized trials for its effect on either classic or late HDN.

To estimate the short-term efficacy and toxicity of sulfasalazine for the treatment of rheumatoid arthritis (RA). ⋯ Sulfasalazine appears to have a clinically and statistically significant benefit on the disease activity of patients with RA. Its effects on overall health status and radiological progression are not clear at this time, but would appear to be modest.

Obstructive sleep apnoea is the periodic reduction (hypopnoea) or cessation (apnoea) of airflow during sleep. The syndrome is associated with loud snoring, disrupted sleep and observed apnoeas. Beside conservative treatments there are a range of 8 broad categories of operative treatments for this condition. Surgical treatments aim to relieve the obstruction by either increasing the surface area ⋯ There is an urgent need for high quality randomised controlled trials to be carried out in the field of surgery for obstructive sleep apnoea. More research should also be undertaken to identify and standardise techniques to determine the site of airways obstructions.
