ReviewProgestagens and anti-progestagens for pain associated with endometriosis.
Endometriosis is a gynaecological condition that presents either with the problem of infertility or with painful symptoms. The clinical observation of an apparent resolution of symptoms during pregnancy gave rise to the concept of treating patients with a pseudo-pregnancy regime. Initially combinations of high dose oestrogens and progestagens were used but this was subsequently replaced by progestogens alone. More recently progestogens of both progestagens and anti-progestagens in the treatment of symptomatiprogestogenssis ⋯ The limited available data suggests that both continuous progestagens and anti-progestagens are effective therapies in the treatment of painful symptoms associated with endometriosis. Progestagens given in the luteal phase are not effective. These conclusions should be accepted cautiously due to a lack of data.

The course of advanced renal cell carcinoma is extremely variable, ranging from spontaneous remission to disease progression refractory to chemotherapy. Immunotherapy has held promise of improved outcomes based on uncontrolled studies and randomized controlled trials generally limited by small size and low power. ⋯ Interferon-alpha provides a modest survival benefit compared to other commonly used treatments and should be considered for the control arm of future studies of systemic agents. Interleukin-2 has not been validated in controlled randomized studies.

Inotropes are widely used in preterm infants to treat systemic hypotension. The most commonly used drugs are dopamine and dobutamine. These agents have different modes of action which may result in different haemodynamic effects. ⋯ Dopamine is more effective than dobutamine in the short term treatment of systemic hypotension in preterm infants. There was no evidence of an effect on the incidence of adverse neuroradiological sequelae (severe periventricular haemorrhage and/or periventricular leucomalacia), or on the incidence of tachycardia. However, in the absence of data confirming long term benefit and safety of dopamine compared to dobutamine, no firm recommendations can be made regarding the choice of drug to treat hypotension.

Enuresis (bedwetting) is a socially disruptive and stressful condition which affects around 15-20% of five year olds, and up to 2% of young adults. Although there is a high rate of spontaneous remission, the social, emotional and psychological costs to the children can be great. ⋯ Desmopressin rapidly reduced the number of wet nights per week, but there was some evidence that this was not sustained after treatment stopped. Comparison with alternative treatments suggested that desmopressin and tricyclics had similar clinical effects, but that alarms produced more sustained benefits. However, based on the available evidence, these conclusions can only be tentative. There was some evidence of minor side effects of desmopressin in the included trials, such as nasal irritation and nose bleeds. However, the risk of water intoxication associated with over-drinking before bedtime has been reported. Patients and their families need to be warned of potential adverse effects and advise

Mortality from Plasmodium falciparum malaria remains high; death and sequelae occur in even in patients treated with antimalarial drugs. Researchers are exploring the effects of adding treatments to the main antimalarial regimens in an attempt to reduce mortality. Iron chelation is one potential chemotherapeutic adjuvant treatment. Before advocating adjunctive therapy, the effects of iron chelators in improving patient outcomes needs to be examined. ⋯ Trends suggestive of both harm (death) and potential benefit (fewer seizures) are demonstrated in this review. It is not possible to comment on time to event outcomes that include coma recovery or parasitaemia as we are clarifying data with the trialists. Whether to conduct further trials will depend on a judgement about potential benefit.
