Cancer of the uterine cervix is one of the leading causes of cancer death among women worldwide. The estimated new cancer cervix cases per year is 500,000 of which 79% occur in the developing countries. Cancer cervix occupies either the top rank or second among cancers in women in the developing countries, whereas in the affluent countries cancer cervix does not even find a place in the top 5 leading cancers in women. ⋯ The accumulated evidence suggests that cervical cancer is preventable and is highly suitable for primary prevention. Sexual hygiene, use of barrier contraceptives and ritual circumcision can undoubtedly reduce cervical cancer incidence. Education, cervical cancer screening of high risk groups and improvement in socio-economic status can reduce cervical cancer morbidity and mortality significantly.

To determine whether antidepressants are clinically effective and acceptable for the treatment of depression in people who also have a physical illness. ⋯ The review provides evidence that antidepressants, significantly more frequently than either placebo or no treament, cause improvement in depression in patients with a wide range of physical diseases. About 4 patients would need to be treated with antidepressants to produce one recovery from depression which would not have occurred had they been given placebo (NNT 4.2, 95% CI 3.2-6.4). Antidepressants seem reasonably acceptable to patients, in that about 10 patients would need to be treated with antidepressants to produce one dropout from treatment which would not have occurred had they been given placebo (NNH 9.8, 95% CI 5.4-42.9). The evidence is consistent across the trials, apart from 2 trials in cancer, where the "atypical" antidepressant mianserin produced significantly less dropout than placebo. Trends towards tricyclics being more effective than SSRIs, but also more likely to produce dropout were noted, but these are based on non-randomised comparisons between trials. Problems with the evidence include most of the trials' use of observers, rather than patients, to decide on improvement, and concentration mainly on symptoms rather than function and quality of life. There is also a possibility of undetected negative trials. Nevertheless, the review provides evidence that use of antidepressants should at least be considered in those with both physical illness and depression. Regarding diagnosis, the existence of a cheap and readily available treatment for depression should encourage detailed assessment of persistent low mood in the physically ill.

Comparative Study
Effect of home-based neonatal care and management of sepsis on neonatal mortality: field trial in rural India.
Neonatal care is not available to most neonates in developing countries because hospitals are inaccessible and costly. We developed a package of home-based neonatal care, including management of sepsis (septicaemia, meningitis, pneumonia), and tested it in the field, with the hypothesis that it would reduce the neonatal mortality rate by at least 25% in 3 years. ⋯ Home-based neonatal care, including management of sepsis, is acceptable, feasible, and reduced neonatal and infant mortality by nearly 50% among our malnourished, illiterate, rural study population. Our approach could reduce neonatal mortality substantially in developing countries.

Meta AnalysisPsychological impact of predicting individuals' risks of illness: a systematic review.
The aim of this review is to determine the frequency and circumstances under which predicting individuals' risk of illness has adverse psychological effects. Using systematic review methodology, the literature was searched for studies that had assessed the adverse psychological outcomes of risk assessment programmes. The outcomes investigated are emotional (anxiety, depression, distress) cognitive (intrusive thoughts, perceptions of health) and behaviour (work absenteeism). ⋯ There was little evidence of any adverse psychological effects of receiving an unfavourable test result. Adverse psychological effects are a common immediate consequence of positive test results following risk assessment. Results from the few experimental studies reviewed suggest that these adverse outcomes should not be seen as inevitable.
