Background

In April 2010 Sierra Leone launched a nationwide program that provides free health care to all pregnant and lactating women and children under 5 years old. This study evaluates the effect that the free health-care program had on pediatric surgical activities of Connaught Hospital.

Methods

The study period was defined as the 20 months before and after April 27, 2010, the start date of the free health-care program. Data on age, gender, diagnosis, and procedure for patients under 5 years of age and the total number of operations were collected from the Connaught Hospital operating room logbook.

Results

The number of operations on children under 5 increased by 500 %, from 42 to 210 cases. This increase was significantly larger than the 17 % increase of 1,393–1,630 seen with operations for patients 5 years and older (p < 0·01).

Conclusion

The decision by the Sierra Leone President to institute a program of free health care for children under 5 has resulted in an increased number of pediatric surgical cases at Connaught Hospital. Efforts should be undertaken to provide additional supplies and equipment and to develop training programs for surgeons and support staff to care for the children in need of surgical care.  相似文献

A 34-y-old man presented to Naivasha District Hospital (NDH) in Naivasha Town, Kenya, with near-complete below-knee amputation and hemorrhage after a hippopotamus attack. Residents from the University of Washington (UW), Departments of Surgery, Anesthesia, and Medicine, were rotating at NDH with the Clinical Education Partnership Initiative, a joint venture of UW and University of Nairobi. These providers met the patient in the operating theater. The leg was mangled with severely traumatized soft tissues and tibia–fibula fractures. The visiting UW Surgery resident (R3) and an NDH medical officer (second-year house officer) performed emergency below-knee completion amputation—the first time either had performed this operation. The three major vessel groups were identified and ligated. Sufficient gastrocnemius and soleus were preserved for future stump construction. The wound was washed out, packed with betadine-soaked gauze, and wrapped in an elasticized bandage. Broad-spectrum antibiotics were initiated. Unfortunately, the patient suffered infection and was revised above the knee. After a prolonged course, the patient recovered well and was discharged home. NDH house officers and UW trainees collaborated successfully in an emergency and conducted the postoperative care of a patient with a serious and challenging injury. Their experience highlights the importance of preparedness, command of surgical basics, humility, learning from mistakes, the expertise of others, a digitally connected surgical community, and the role of surgery in global health. These lessons will be increasingly pertinent as surgical training programs create opportunities for their residents to work in developing countries; many of these lessons are equally applicable to surgical practice in the developed world.  相似文献

Africa is the continent most severely affected by the global HIV-1 epidemic, with east and southern Africa in general more severely affected than west and central Africa. Differences in the spread of the epidemic can be accounted for by a complex interplay of sexual behaviour and biological factors that affect the probability of HIV-1 transmission per sex act. Sexual behaviour patterns are determined by cultural and socioeconomic contexts. In sub-Saharan Africa, some traditions and socioeconomic developments have contributed to the extensive spread of HIV-1 infection, including the subordinate position of women, impoverishment and decline of social services, rapid urbanisation and modernisation, and wars and conflicts. Populations in many parts of Africa are becoming trapped in a vicious circle as the HIV-1 epidemic leads to high mortality rates in young and economically productive age groups, and thus leads to further impoverishment. Interventions to control HIV-1 should not only target individuals, but also aim to change those aspects of cultural and socioeconomic context that increase the vulnerability to HIV-1 of people and communities.  相似文献

Abstract A survey of orthodontic treatment need was carried out among randomly selected rural Nigerian adolescents using the index of orthodontic treatment need. Altogether, 704 subjects (381 boys and 323 girls) aged 12–18 years (mean 14.8, SD 1.79) were recruited in the study. The results indicated that 12.6% of the population were in objective need of orthodontic treatment. Whilst there was a discrepancy in the proportions of Nigerian adolescents needing orthodontic treatment on aesthetic and dental health grounds, girls were found to have a more attractive dental appearance and less orthodontic treatment need than boys. However, the differences were not statistically significant (P > 0.05). The correlation between the orthodontist's and the subject's rating of dental appearance was found to be low (r=0.35). The study also provided reliable baseline data for planning orthodontic services in Nigeria especially in areas where there are no dental services.  相似文献

This study examined the impact of controllability of onset (i.e., means of transmission), disease type (HIV and lung cancer), and culture (Kenya and U.S.) on stigmatizing attitudes and goals for supportive communication. Four hundred sixty-four Kenyan students and 526 American students, and 441 Kenyan nonstudents and 591 American nonstudents were randomly assigned to 1 of 12 hypothetical scenario conditions and asked to respond to questions regarding 3 different types of stigmatizing attitudes and 6 types of supportive communication goals with respect to the character in the scenario. Means of transmission had a strong effect on the blame component of stigma, but none on cognitive attitudes and social interaction components. Similarly, although an effect for means of transmission emerged on intention to provide "recognize own responsibility" and "see others' blame" types of support, no effect was evident for most other supportive interaction goals. Although effects for culture were small, Kenyan participants, student and nonstudent alike, were not as quick as American participants to adopt goals of communicating blame in any direction. Implications for measurement of stigma in future research are discussed.  相似文献
