Association of dental practice as a risk factor in the development of carpal tunnel syndrome.

STATEMENT OF PROBLEM: Carpal tunnel syndrome (CTS) is an important cause of work disability. There is controversy over the relation between carpal tunnel syndrome and occupation. The aim of this study was to assess the relationship between the time-span of practicing dentistry and the role of dominant hands in the development of carpal tunnel syndrome. MATERIALS AND METHOD: In this descriptive cross sectional study, 40 dentists and dental students (15 women and 25 men) undertook the electroneuro-diagnostic test in both hands by an electromyogram (EMG) and they were also evaluated in terms of self- reported clinical symptoms. RESULTS: 17.5% of participants were diagnosed to have decreased nerve conduction velocity while10% had reported clinical symptoms of CTS. Both dominant and non-dominant hands were involved. Within cases who were diagnosed as having median nerve neuropathy, 87.5% worked more than 20 hours per week. 57% had 17-23 years of dental practice experience and 14.2% of cases had10-16 years of practice in dentistry. CONCLUSION: The high rate of CTS symptoms, in both dominant and non-dominant hand among dental practitioners with more years of dental practice, indicates a prequisite for particular attention, then sufficient education on the major risk factors causing this problem. Early diagnosis of these symptoms may improve the future management of the disease.

Misoprostol and active management of the third stage of labor.

OBJECTIVE: To compare current practices for the active management of the third stage of labor (AMTSL) with the use of 600 mug of oral misoprostol. METHODS: An operations research study was designed to compare blood loss with current AMTSL practices and misoprostol use. RESULTS: Women in the misoprostol group were less likely to bleed 500 ml or more (adjusted odds ratio, 0.30; 95% confidence interval, 0.16-0.56) compared with those in the current practices group. In the current practices group 73% women required interventions because of postpartum hemorrhage, compared with 11% in the misoprostol group. CONCLUSION: In situations where oxytocin and or ergometrine are not consistently and appropriately used during third stage of labor, misoprostol should be considered for inclusion in the AMTSL protocol.

Controlling postpartum hemorrhage after home births in Tanzania.

OBJECTIVES: Determine safety of household management of postpartum hemorrhage (PPH) with 1000 microg of rectal misoprostol, and assess possible reduction in referrals and the need for additional interventions. METHODS: Traditional birth attendants (TBAs) in Kigoma, Tanzania were trained to recognize PPH (500 ml of blood loss). Blood loss measurement was standardized by using a local garment, the "kanga". TBAs in the intervention area gave 1000 microg of misoprostol rectally when PPH occurred. Those in the non-intervention area referred the women to the nearest facility. RESULTS: 454 women in the intervention and 395 in the non-intervention areas were eligible. 111 in the intervention area and 73 in the non-intervention had PPH. Fewer than 2% of the PPH women in the intervention area were referred, compared with 19% in the non-intervention. CONCLUSION: Misoprostol is a low cost, easy to use technology that can control PPH even without a medically trained attendant.
