Hepatitis B and C in doctors and dentists in Nigeria

We surveyed a random sample (n = 75) of doctors and dentists at University College Hospital, Ibadan, Nigeria. They were offered anonymous testing for hepatitis B surface antigen (HBsAg), hepatitis Be antigen (HBeAG), antibodies to hepatitis B core antigen (anti-HBc) and to hepatitis C virus (anti-HCV), by enzyme immunoassay. The results suggest a high prevalence of hepatitis B virus (HBV) with a high potential of transmissibility, as well as a high prevalence of HCV infection. The majority of the doctors and dentists use universal precaution for protection against viral hepatitis on < 50% of the occasions when they carry out procedures on their patients. Infection with HBV was associated with type of specialty (surgeons, dentists) and lack of HBV vaccination (p < 0.05). After logistic regression, these factors were independently associated with HBV infection (p < 0.05). Sixty (80%) had not received prior HBV vaccination. Unvaccinated personnel were more likely to be surgeons, dentists, < 37 years of age, and have fewer years of professional activity (p < 0.05). After logistic regression, only fewer years of professional activity remained independently associated with lack of vaccination (p < 0.05). To reduce the occupational exposure of HBV, universal precautions must be rigorously adhered to when the doctors and dentists carry out procedures on their patients, and all health-care workers should be vaccinated with HBV vaccine and the HCV vaccine, when it becomes available.      

Obstetric quality assurance to reduce maternal and fetal mortality in Kano and Kaduna State hospitals in Nigeria

Objective

To achieve Millennium Development Goals 4 and 5 in Nigeria, a quality assurance project in obstetrics in 10 hospitals in northern Nigeria was established to improve maternal and fetal outcome.

Methods

The project commenced in January 2008 with assessment and improvement of the structure of the 10 hospitals. Continuous maternal and fetal data collection and analysis were conducted from 2008 to 2009 by means of a maternity record book and structured monthly summary form. The quality of hospital infrastructure and equipment was also assessed.

Results

The mean maternal mortality ratio (MMR) was reduced from 1790 per 100 000 births in the first half of 2008 to 940 per 100 000 births in the second half of 2009. The average fetal mortality ratio (FMR) decreased slightly from 84.9 to 83.5 per 1000 births. There was an inversely proportional relationship between the total number of deliveries in a hospital and MMR and FMR. There was a close correlation between the MMR and the equipment status and hygiene conditions of the hospitals.

Conclusion

Continuous monitoring of quality assurance in maternity units raised the awareness of the quality of obstetric performance and improved the quality of care provided, thereby improving MMR.     

A double-blind, randomized, placebo-controlled trial of misoprostol and routine uterotonics for the prevention of postpartum hemorrhage

Objective

To assess the effects of 400-μg sublingual misoprostol plus routine uterotonics on postpartum hemorrhage.

Methods

A double-blind, placebo-controlled, randomized study was performed. After delivery of the child, eligible women received routine uterotonics and were randomly allocated to receive 400-μg misoprostol or placebo sublingually. The primary outcome measure was blood loss of at least 500 mL within 1 hour of taking the trial tablets.

Results

In total, 672 women received misoprostol and 673 received placebo. The baseline data were similar for both groups. Misoprostol plus routine uterotonics reduced postpartum blood loss, but the effect was not significant for blood loss of at least 500 mL (relative risk [RR] 0.96; 95% confidence interval [CI], 0.63-1.45) or blood loss of at least 1000 mL (RR 0.50; 95% CI, 0.15-1.66). Misoprostol also reduced the need for non-routine oxytocin, manual removal of the placenta, and hysterectomy, but these differences were not significant either. Misoprostol was associated with pyrexia and moderate/severe shivering. There was no death in either group.

Conclusion

Misoprostol plus routine uterotonics resulted in modest reductions of blood loss in the third stage of labor, but the effects did not reach statistical significance. Larger studies are recommended.     

Relative morbidity of abdominal myomectomy for very large uterine fibroids in a developing country hospital

Background  

Data on comparative outcomes of abdominal myomectomy for varying uterine sizes that could guide informed decision by women and clinicians in resource-constrained settings are scarce.     

Within-Group Differences Between Native-Born and Foreign-Born Black Men on Prostate Cancer Risk Reduction and Early Detection Practices

To better address prostate cancer disparities, we investigated the differences among US-born, African-born, and Caribbean-born Black men on prostate cancer risk reduction and early detection behaviors. Data were collected from over 3,400 Black men in five cities in Florida. One-way analysis of variance was used to explore the ethnic variations among the three study groups. We found that there were significant differences among the three groups. The US-born Black men had the highest knowledge, were most likely to have health insurance, and consume the most meat compared to African-born, and Caribbean-born Black men. African-born Black men were most likely to use chemoprevention products and discuss prostate cancer risk-reduction and early detection with a physician. Given the significant number of foreign-born Blacks in the US, it is important to disaggregate the data of US-born and foreign-born Blacks to develop effective programs and policies to address the needs of each group.     

Scourge of intra-partum foetal death in Sub-Saharan Africa

Intra-partum foetal death has been variously defined.However, a definition adopted at a technical consultation in 2006 is employed in this review. The quality of intrapartum care is a crucial factor for pregnancy outcome for both mothers and new-borns. Intra-partum stillbirth is defined as late foetal death during labour, which clinically presents as fresh stillbirth. The largest proportion of the world's stillbirths occurs in the late preterm, term and intra-partum periods. The Western Pacific region has the greatest reduction in stillbirth with a 3.8% annual decline between 1995 and 2009; however, the annual decline in the African region is less than 1%. Caesarean delivery is still uncommon, especially in rural areas: 1% of births in rural Sub-Saharan Africa and 5% in rural South Asia are by caesarean delivery; 62% of stillbirths occurred during the intra-partum period; 61.4% of stillbirths are attributable to obstetrical complications. Preventive measures aimed at reducing the incidence of intra-partum foetal death entail all measures aimed at improving quality antenatal care and preventing intrapartum asphyxia. This review discusses intra-partum foetal deaths from a Sub-Saharan African perspective. It explores the contribution of research within the region to identifying its impact on new-born health and potential cost-effective policy interventions.     

Administration of analgesics in patients with acute abdominal pain: a survey of the practice of doctors in a developing country

Background

Analgesic use, particularly opioids in the emergency situation in patients with acute abdominal pain, generally has been avoided in the past; however, newer evidence has shown that the practice should be encouraged. In spite of this, many physicians still withhold analgesics in this clinical situation.

Aims

The aim of the study was to evaluate the current opinion and practice of Nigerian doctors regarding the use of analgesics for patients with acute abdominal pain during the initial evaluation.

Methods

A one-page survey was distributed by two of the authors to Nigerian doctors from different parts of the country during conferences, seminars and meetings on different occasions in 2007. Demographic data and information regarding medical specialty, post-qualification experience, analgesic use in acute abdominal pain, and effects on diagnosis and outcome were included. The respondents were then classed into two sets of two groups using specialty (surgical and non-surgical) and post-qualification experience (less than 10 years, “less experienced;” over 10 years, “experienced”).

Results

There were 539 respondents. The male:female ratio was 12:1. Of the respondents, 50.4% would withhold analgesics if the diagnosis was unclear, and a further 12% would do the same if a surgical opinion was required. Reasons for withholding analgesics were (1) believing that analgesics interfered with evolution of signs (84.4%), (2) believing that the diagnosis would be impaired (77.9%) and (3) believing that analgesics would have an adverse effect on outcome (54.5%). Specialty or length of post-qualification experience did not significantly influence this practice (p < 0.05).

Conclusion

The study has shown that the dogma that analgesics are harmful in patients with acute abdominal pain is still firmly entrenched in the practice of the surveyed Nigerian doctors. This belief is not significantly affected by specialty or post-qualification experience.
