Vaccines for post-exposure prophylaxis against varicella (chickenpox) in children and adults.
Live attenuated varicella vaccines for the prevention of varicella (chickenpox) has been demonstrated both in randomised controlled trials (RCTs) and in population-based immunisation programmes in countries such as the United States. However, many countries do not routinely immunise children against varicella, and exposures continue to occur. Although the disease is often mild, complications such as secondary bacterial infection, pneumonitis and encephalitis occur in about 1% of cases, usually leading to hospitalisation. The use of varicella vaccine in persons who have recently been exposed to the varicella zoster virus has been studied as a form of post-exposure prophylaxis (PEP). ⋯ These small trials suggest varicella vaccine administered within three days to children following household contact with a varicella case reduces infection rates and severity of cases. No RCTs for adolescents or adults were identified. However safety was not adequately addressed.

Evidence from observational studies suggests that diets high in omega-3 long-chain polyunsaturated fatty acids (PUFA) may protect people from cognitive decline and dementia. The strength of this potential protective effect has recently been tested in randomized controlled trials. ⋯ Direct evidence on the effect of omega-3 PUFA on incident dementia is lacking. The available trials showed no benefit of omega-3 PUFA supplementation on cognitive function in cognitively healthy older people. Omega-3 PUFA supplementation is generally well tolerated with the most commonly reported side-effect being mild gastrointestinal problems. Further studies of longer duration are required. Longer-term studies may identify greater change in cognitive function in study participants which may enhance the ability to detect the possible effects of omega-3 PUFA supplementation in preventing cognitive decline in older people.

Premature ejaculation (PE) is a very common sexual dysfunction among patients, and with varying prevalence estimates ranging from 3% to 20%. Although psychological issues are present in most patients with premature PE, as a cause or as a consequence, research on the effects of psychological approaches for PE has in general not been controlled or randomised and is lacking in long-term follow up. ⋯ Overall, there is weak and inconsistent evidence regarding the effectiveness of psychological interventions for the treatment of premature ejaculation. Three of the four included randomised controlled studies of psychotherapy for PE reported our primary outcome (Improvement in IELT), and the majority have a small sample size. The early success reports (97.8%) of Masters and Johnson could not be replicated. One study found a significant improvement from baseline in the duration of intercourse, sexual satisfaction and sexual function with a new functional-sexological treatment and behavior therapy compared to waiting list. One study showed that the combination of chlorpromazine and BT was superior to chlorpromazine alone. Randomised trials with larger group samples are still needed to further confirm or deny the current available evidence for psychological interventions for treating PE.

I am increasingly bemused by the narrowing and blinkered view of training to becoming a GP. Rosenthal and Chana1 comment 'many trainees still spend part of this time in posts that offer traditional hospital-based experience that may not reflect the context of new community based service models'. Cautiously I would like to add the comment 'so what?' We do want 'well rounded' GPs, people open to new ideas, and who are open to 'lifelong learning.' Many who qualified at a similar time to me will have done hospital jobs as 'part of the team.' Six months at the end of which we were hopefully competent but also confident. ⋯ This also seems to becoming more difficult and not encouraged generally while trying to achieve CCT. That great idea of learner-led education, particularly for trainees, seems to have gone out of the window. I suppose I am saying, can we be a bit more generic in our training years, widen our horizons again, and use First5 to help settle doctors into the rewarding job we do?
