Review Meta AnalysisSequential combination of glucocorticosteroids and alfa interferon versus alfa interferon alone for HBeAg-positive chronic hepatitis B.
Chronic hepatitis B has serious effects on morbidity and mortality. Alfa interferon has been shown to increase the rates of HBeAg-clearance as well as seroconversion to anti-HBe, but response rates are unsatisfactory. Glucocorticosteroid pretreatment may increase the response to alfa interferon. ⋯ Pretreatment with glucocorticosteroids before treatment with alfa interferon in patients with hepatitis B 'e' antigen positive chronic hepatitis B may be more effective than treatment with alfa interferon alone with regard to loss of hepatitis B 'e' antigen and hepatitis B virus DNA, but evidence for effect on clinical outcomes is lacking.

ReviewConservative treatment for closed fifth (small finger) metacarpal neck fractures.
Subcapital fractures of the fifth metacarpal bone, meaning fractures just below the knuckle of the little finger, account for approximately 20% of all hand fractures. Currently, there is no consensus concerning the optimal management of these fractures. Traditionally, treatment consists of closed reduction and external splinting in a neutral position using plaster of Paris (POP), involving the metacarpal joint, the proximal interphalangeal joint and the carpo-metacarpal joint. An alternative treatment strategy is functional treatment using taping or bracing that does not restrict movement. ⋯ No included studies reported our primary outcome measure of interest, validated hand function. There was heterogeneity between the studies, which were of limited quality and size. No single non-operative treatment regimen for fracture of the neck of the fifth metacarpal can be recommended as superior to another in result. Further research is definitely warranted.

Anticonvulsant drugs have been used in the management of pain since the 1960s. The clinical impression is that they are useful for chronic neuropathic pain, especially when the pain is lancinating or burning. Readers are referred to reviews of carbamazepine and gabapentin in the Cochrane Library which replace the information on those drugs in this review. Other drugs remain unchanged at present in this review ⋯ Although anticonvulsants are used widely in chronic pain surprisingly few trials show analgesic effectiveness. Only one studied considered cancer pain. There is no evidence that anticonvulsants are effective for acute pain. In chronic pain syndromes other than trigeminal neuralgia, anticonvulsants should be withheld until other interventions have been tried. While gabapentin is increasingly being used for neuropathic pain the evidence would suggest that it is not superior to carbamazepine.

ReviewLaparoscopic "drilling" by diathermy or laser for ovulation induction in anovulatory polycystic ovary syndrome.
Problems in inducing ovulation in women with polycystic ovary syndrome (PCOS) and anovulation (failure to ovulate) are well recognised. Surgical ovarian wedge resection was the first established treatment for anovulatory PCOS patients but was largely abandoned due to the risk of post-surgical adhesions and the introduction of medical ovulation induction with clomiphene and gonadotrophins. However patients with PCOS treated with gonadotrophins often have an over-production of follicles and are exposed to the risks of ovarian hyperstimulation syndrome (OHSS) and multiple pregnancy. Moreover ovulation induction with gonadotrophins, though effective, is an expensive, inconvenient and time-consuming treatment requiring intensive monitoring. Surgical therapy with laparoscopic ovarian "drilling" (LOD) may avoid or reduce the need for gonadotrophins or may facilitate their use. The procedure can be done on an outpatient basis with less trauma and fewer postoperative adhesions. Many uncontrolled observational studies have claimed that ovarian drilling is followed, at least temporarily, by a high rate of spontaneous ovulation and conception, and/or that subsequent medical ovulation induction becomes easier. ⋯ There was no evidence of a difference in the live birth rate and miscarriage rate in women with clomiphene resistant PCOS undergoing LOD compared to gonadotrophin treatment. The reduction in multiple pregnancy rates in women undergoing LOD makes this option attractive. However, there are ongoing concerns about long term effects of LOD on ovarian function.

ReviewConservative management of symptomatic and/or complicated haemorrhoids in pregnancy and the puerperium.
Haemorrhoids (piles) are swollen veins at or near the anus, normally asymptomatic. They do not constitute a disease, unless they become symptomatic. Pregnancy and the puerperium predispose to symptomatic haemorrhoids, being the most common ano-rectal disease at these stages. Symptoms are usually mild and transient and include intermittent bleeding from the anus and pain. Depending on the degree of pain, quality of life could be affected, varying from mild discomfort to real difficulty in dealing with the activities of everyday life. Treatment during pregnancy is mainly directed to the relief of symptoms, especially pain control. The so-called conservative management includes dietary modifications, stimulants or depressants of the bowel transit, local treatment, and phlebotonics (drugs that cause decreased capillary fragility, improving the microcirculation in venous insufficiency). For many women, symptoms will resolve spontaneously soon after birth, and so any corrective treatment is usually deferred to some time after birth. Thus, the objective of this review is to evaluate the efficacy of conservative management of piles during pregnancy and the puerperium. ⋯ Although the treatment with oral hydroxyethylrutosides looks promising for symptom relief in first and second degree haemorrhoids, its use cannot be recommended until new evidence reassures women and their clinicians about their safety. The most commonly used approaches, such as dietary modifications and local treatments, were not properly evaluated during pregnancy and the puerperium.
