Vaginal candidiasis (moniliasis or thrush) is a common and frequently distressing infection for many women. It is even more common in pregnancy. ⋯ Topical imidazole appears to be more effective than nystatin for treating symptomatic vaginal candidiasis in pregnancy. Treatments for seven days may be necessary.

Sore throat is a very common reason for people to attend for medical care. Sore throat is a disease that remits spontaneously, that is, 'cure' is not dependant on treatment. Nonetheless primary care doctors commonly prescribe antibiotics for sore throat and other upper respiratory tract infections. ⋯ Antibiotics confer relative benefits in the treatment of sore throat. However, the absolute benefits are modest. Protecting sore throat sufferers against suppurative and non-suppurative complications in modern Western society can only be achieved by treating many with antibiotics who will derive no benefit. Antibiotics shorten the duration of symptoms, but by a mean of only about half of one day at day 3 (the time of maximal effect), and by about eight hours overall.

Leptospirosis is an infectious disease transmitted by animals. Death occurs in about five per cent of the patients. In clinical practice, doxycycline is widely used for prevention. ⋯ Prophylaxis of leptospirosis may be achieved by administrating doxycycline to soldiers training in endemic areas with a high risk of exposure to leptospirosis. Whether these findings apply to other scenarios or not remains to be proven.

Since the advent of in-vitro fertilisation (IVF) the role of infertility surgery has diminished. This type of surgery is still however widely performed.and there are many different surgical techniques that can be used to repair blocked or damaged Fallopian tubes. Most evidence in this area comes from uncontrolled series. ⋯ 1) INFERTILITY SURGERY VERSUS NO TREATMENT One non RCT compared open adhesiolysis versus no treatment and found significantly more pregnancies in the treatment group compared with the control group. 2) INFERTILITY SURGERY VERSUS ALTERNATIVE TREATMENTS. No RCTs investigated the role of infertility surgery compared with In vitro fertilisation (IVF). There were no studies comparing tubal surgery for proximal tubal occlusion versus hysteroscopic or radiologically controlled recannulation. 3) MAGNIFICATION FOR INFERTILITY SURGERY There was a non significant reduction in pregnancy rate when the operating microscope (magnification x4-x16) was used rather than Loupes (magnification x2-x4.5) in the only RCT to study this. One RCT randomised patients to microsurgery versus a macrosurgical technique involving a prosthesis. There were more pregnancies in the microsurgery group, but this was not significant, and the trial consisted of only 18 participants. All the non-RCT studies comparing microsurgery with macrosurgery had a historical control group. Meta-analysis of studies investigating the role of magnification for adhesiolysis and for salpingostomy revealed a statistically significant increase in pregnancy rates and reduction in ectopic pregnancy rates for microsurgery versus macrosurgery for both procedures. For reversal of sterilisation there was a significant improvement in term pregnancy rates, and a non significant reduction in ectopic rates There was no significant difference between microsurgical and macrosurgical treatment of proximal tubal occlusion for any outcome. 4) THE USE OF LASER AT INFERTILITY SURGERY Two RCTs investigated the use of the CO2 laser at infertility surgery. There was no significant difference in pregnancy outcome after adhesiolysis, or salpingostomy. Two non randomised studies also investigated the role of the laser. Overall there was no significant difference using the CO2 laser compared with standard techniques for adhesiolysis, salpingostomy or reversal of sterilisation. 5) LAPAROSCOPIC INFERTILITY SURGERY Four studies investigated the use of laparoscopic techniques for infertility surgery. There were no RCTs. One study compared laparoscopic versus open

ReviewChorion villus sampling versus amniocentesis for prenatal diagnosis.
Amniocentesis test results are usually available only after 18 weeks gestation. Chorion villus sampling (CVS) may be performed transabdominally or transvaginally, usually between 10 and 12 weeks gestation. ⋯ The increase in miscarriages after chorion villus sampling compared to amniocentesis appear to be procedure related. Second trimester amniocentesis appears to be safer than chorion villus sampling. The benefits of earlier diagnosis with chorion villus sampling must be set against the greater risk of pregnancy loss.
