Incidence of umbilical hernia in African children: redefinition of "normal" and reevaluation of indications for repair.

This study was undertaken to assess the degree of ubiquity of umbilical hernias (UHs) in Nigerians and to determine if a laissez faire approach to the presence of UHs is justified. A prospective evaluation was conducted of the umbilical area of 4052 Nigerians living in the vicinity of the Baptist Medical Centre (BMCO) in Ogbomoso, Nigeria. The diameter of the fascial defect was measured with the subject supine and the protrusion of the umbilical skin with the subject erect. Subjects were divided into three groups: group 1 (1 month to 18 years old); group 2 (older than 18 years); and group 3 (pregnant women in an antenatal clinic). "Outies" (defined as any protrusion of the umbilical tip past the periumbilical skin) were present in 92% of group 1, 49% of group 2, and 90% of group 3 subjects. UHs (defined as protrusion of at least 5 mm and diameter of at least 10 mm) were present in 23% of group 1, 8% of group 2, and 15% of group 3 subjects. Spontaneous closure of UHs seems to occur until age 14. A retrospective analysis identified 11 patients undergoing emergency operations for UH-related problems during the past 15 years. With a low incidence and 0% mortality rate associated with management of these emergencies, a policy of prophylactic repair is not justified at BMCO. Because most of the children we examined had outies, repair for cosmetic reasons is rarely requested. The only logical indication for repair of UHs at BMCO is incarceration, and this rarely occurs.

Prospective randomized comparison of two preoperative skin preparation techniques in a developing world country.

Povidone-iodine (PI) is a scarce and expensive item for some hospitals in developing countries. This prospective, randomized study was performed at Baptist Medical Centre (BMCO) in Ogbomoso, Nigeria to determine if the use of PI for preoperative skin preparation would result in a lower postoperative wound infection rate and to identify other factors influencing the infection rate. Two hundred patients undergoing inguinal hernia repair were randomized to receive skin preparation with either: (1) locally available, inexpensive market soap and methylated spirit or (2) imported PI. The two groups were equally stratified. The overall postoperative wound infection rate was 5.5%, and there was no significant difference between the groups (5.1% vs. 5.9%). Factors that did not affect the infection rate included gender, age, type of anesthesia, type or duration of the operative procedure, and number of breaks in optimal technique. There were eight abscesses and three cases of cellulitis without suppuration diagnosed an average of 10 days postoperatively. Staphylococcus was the only bacterium identified on Gram stain or culture. The expense of procuring PI is not justified at BMCO. Available funds may better be used for preoperative antibiotics or for improvement in hospital infrastructure, which should result in fewer breaks in optimal operating room technique.

Complications of fracture treatment by traditional bonesetters in southwest Nigeria.

BACKGROUND: Traditional bonesetters (TBS) practice widely in Nigeria. OBJECTIVE: Our aim was to evaluate the types of complications seen in patients previously treated by TBS and to assess factors that may predispose to the complications. METHODS: We carried out a prospective non-randomized controlled study in a general hospital in southwest Nigeria. All patients brought into the hospital over the 10-month study period with fractures who had been treated previously by a TBS and, as a control, all patients brought directly to and treated by us were studied. Each patient was assessed and prescribed the most appropriate treatment for their fracture: reduction, immobilization (operatively and otherwise) and physiotherapy. Malunion, non-union, delayed union, gangrene, stiffness of joints and loss of joint motion, Volkman's ischaemic contracture and tetanus were all investigated. RESULTS: Over half of the patients in the TBS subgroup had malunion, and a quarter had non-union. Only one out of the 36 (2.8%) had no complaints and was satisfied with the outcome of treatment of his fractures by the TBS. In the orthodox subgroup, there were seven complications as a result of treatment of a total of 49 bones (14%). Most of the complications involved the loss of joint motion. CONCLUSIONS: There were no statistically significant associations between the complications recorded and the ages of the patients, types of bone fractured or the duration of treatment in patients who were in the TBS subgroup. The introduction of a health insurance scheme in Nigeria may make it easier for individuals and families to be able to afford proper fracture treatment in hospitals.

Operative management of thyroid abnormalities in a general medical practice hospital in sub-Saharan Africa.

This is a retrospective analysis of 82 patients undergoing thyroid operations in a general medical practice hospital in sub-Saharan Africa. All patients complained of neck swelling, and in 75% of patients this was the only symptom. Indications for operation included cosmesis in 74%, suspected malignancy in 13%, hyperthyroidism in 7% and pressure symptoms in 5%. Operative complications included recurrent laryngeal nerve injury in two (2.4%), wound haematoma in two (2.4%), wound infection in three (3.6%) and hypoparathyroidism in one (1.2%). There were no deaths and no instances of thyroid storm. Thyromegaly can be operatively managed in a hospital such as ours with a relatively low morbidity rate using conservative gland extirpation techniques. This conservative approach may result in under treatment for thyroid malignancies but should result in a lower incidence of recurrent nerve damage and hypoparathyroidism in the majority of people who undergo thyroidectomy solely for cosmetic indications.
