The retained urinary catheter.

Retention of urinary catheters is an increasing complication in our practice. We have reported 18 patients seen over a 6-month period during which 528 catheterizations were done, representing an incidence of 3.4%. Various forms of management were offered and blind percutaneous suprapubic puncture (BPSP) was found to be simple and effective. One out of 13 patients, however, undergoing BPSP developed transient haematuria. The high incidence of malfunctioning catheter balloon mechanisms may be due to poor quality equipment or lack of appropriate storage facilities.

Ascarid granuloma presenting as pseudotumour.

Three patients with histologically confirmed ascarid granuloma who presented clinically with abdominal masses simulating abdominal tuberculosis or lymphoma are described. The clinical course of one patient was complicated by the formation of a spontaneous faecal fistula and perforation of the terminal ileum. In two cases there was rupture of the inflammatory pseudotumour through the anterior abdominal wall.

Schistosomiasis of the appendix.

The clinicopathological features of schistosomiasis of the appendix are discussed, based on the clinical presentation, operative findings and morphological changes in the specimens of patients seen in Ibadan between 1980 and 1989. Schistosoma haematobium was implicated as the causal agent of a granulomatous inflammatory reaction with eosinophilia and fibrosis. Intramuscular oviposition was associated with frank acute appendicitis, and serosal involvement resulted in peritoneal adhesions, with ileoileal intussusception in one patient. The actual role of schistosomal infestation as a contributory factor in appendicitis is still open to debate, but the diagnosis must be entertained in patients in the tropics with features of acute appendicitis or recurrent abdominal pain.

Job stress associated with surgical training in Nigeria.

Surgical residency training is acknowledged as being stressful, however the degree of stress, factors causing it, methods of coping with it, and the incidence of substance abuse has not been previously studied in our environment. We therefore used a self-administered questionnaire to survey 100 Nigerian Surgical Residents of whom 72 responded in September 1995. Our result shows that our residents spend 39.8, 36.8 and 23.3 percent of their time on patient care, educational activities and ancillary care, respectively. Eighty-nine percent of them considered their work to be stressful mainly because of lack of facilities and the unstructured nature of the program. Physical exhaustion, irresponsible behavior and sleep disorders were some of the abnormalities suffered as a result of this. In all, 5.6% rated the stress as severe, while 69.4% considered it moderate. Examinations produced the most stress, followed by operating sessions and patient care. Overall, substance abuse was uncommon with 16.7% claiming to have used alcohol in the one month preceding the study, but 8.3% claimed to need alcohol in order to function. Tobacco, benzodiazepine and barbiturates are some of the substances that our respondents have abused. There was no reported abuse of cannabis, heroin, cocaine, LSD or other psychotropic drugs. We conclude that though stress is inevitable during surgical training, some of the causes can be ameliorated. There is need to reduce the amount of time residents spend on ancillary care, while the current methods of examinations should be reconsidered to incorporate current adult learning theories. Residents should get adequate time for rest and recreation while exposure to modern surgical training in better-endowed centers should be incorporated into the training programme.

Changing clinicopathological profile of intussusception in Nigeria--a 20-year review.

BACKGROUND/AIMS: Intussuception was a common cause of intestinal obstruction at the University College Hospital, Ibadan. A peculiar type characterized by being ceco-colic, and found most commonly in adults, was the commonest variety found, but over the last few years this type of intussusception appears to have reduced in incidence. The aim of the study is to define the relative incidence of intussusception and the contribution of the various types of the overall incidence as seen at the University College Hospital, Ibadan, Nigeria. METHODOLOGY: Review of case notes and the surgical pathology records of all cases of Intussusception seen at the University College Hospital, Ibadan between 1975 and 1994 was done. RESULTS: There was a 48.1% decline in the absolute number of cases seen during the period of the study, and this decline was more among adult cases than infantile intussusception. The mean age of presentation of infantile intussusception was 8 months, while it was 42 years for adults. The classical triad of vomiting, pain and bloody stool was seen in only 15% of cases. Morbidity and mortality rates were high at 18 and 8.5% respectively and this was related to delayed presentation. CONCLUSIONS: The incidence of intussusception has fallen in the community studied and this decline has affected the adult age group and the ceco-colic type of intussusception more. Late presentation is a feature of most cases and is related to the high mortality and morbidity rates seen.

Surgery of toxic goitre in non-euthyroid patients: a preliminary report.

In recent years, the cost of medical care has skyrocketed and since medical treatment is not free, some drugs are now beyond the reach of some patients. One of such drugs is the antithyroid drug, carbimazole, which has been priced beyond the reach of our thyrotoxic patients. We have therefore been forced to operate on these patients whenever they present, even while thyrotoxic. The principle of our management is to anticipate the development of thyroid crises and to prevent its occurrence post-operatively by using saturated solution of potassium iodide (SSKI) or Lugol's iodine, propranolol, diazepam, and hydrocortisone. This is a preliminary report of the first twelve consecutive patients so treated.

Emergency non-obstetrics surgery during pregnancy.

Female constitute the majority of the population in Nigeria according to the 1991 census. Since most of these are young women in childbearing age, it is to be expected that the need for emergency, non-obstetric surgery will occasionally arise in them. This review article sets out a consideration of the anatomical and physiological factors that influence presentation, diagnosis therapy and outcome in these patients. The various common clinical scenarios are discussed and their outcome reviewed.

Breast cancer in Nigeria.

Breast cancer is now the commonest malignancy affecting women in Nigeria. It is likely to become an important public health issue in the next millennium. Recent years have witnessed an explosion in knowledge about the basic sciences of the disease, including the genetic basis and the pathology. These changes are leading to revisions in the management of the disease with a positive impact on prognosis. In this review, the recent developments in the various aspects of breast cancer are reviewed with reference to how they affect the disease in this environment.

Fascia lata autograft for orbital floor reconstruction.

Enophthalmos and diplopia are two major complications that result from a downward displacement of the eyeball. A case in which a fascia lata autograft was used to prevent these complications is presented. When covered by a flap with rich blood supply, this autograft can be used as a good substitute for alloplastic materials.

Anterior abdominal wall reconstruction with fascia lata.

Anterior abdominal wall is a complex fasciomuscular structure, defects of which may arise as a result of infection, trauma, malignancy and herniation. Different techniques have been devised to repair these defects with varying result, availability and cost implications. In the communication, the use of fascia lata for repair of major anterior abdominal wall defect in five patients is reported. The result suggests that this is a useful technique that is associated with satisfactory outcome and minimal morbidity.

Osteogenic sarcoma in the breast--case report of a diagnostic dilemma.

Breast cancer is the leading cancer in females worldwide, the vast majority being carcinomas, and only 0.2-0.3% being sarcomas. Of the mammary sarcomas, extra-osseous osteogenic sarcomas constitute a small heterogeneous group. This communication reports a case of primary extra-osseous osteogenic sarcoma occurring in the breast of a48-year-old female, and presents a literature review of this condition. A pre-requisite for the diagnosis of primary mammary osteogenic sarcoma is the exclusion of an osteogenic sarcoma arising from the underlying ribs or sternum. Like all other osteogenic sarcomas in general, these neoplasms are characterized by the direct formation of osteoid matrix by the tumour cells. Primary osteogenic sarcoma of the breast may arise from metaplastic sarcomatous transformation of neoplastic cells in a primary breast carcinoma, fibroadenoma, malignant phyllodes tumour, or may exceptionally represent a nonphyllodes sarcoma of the breast arising from the soft tissues of an otherwise normal or previously irradiated breast.

The immunization status and level of knowledge about hepatitis B virus infection among Nigerian surgeons.

Hepatitis B virus (HBV) infection is an occupational risk of surgeons especially in developing countries where asymptomatic carrier rate is about 15%. Despite better knowledge about mode of transmission and methods of prevention including use of active immunization, it still remains a threat. In this study, a questionnaire survey of Nigerian surgeons was conducted to ascertain their knowledge, and immunization status against HBV infection. Our study showed a 9.3% incidence of clinical HBV infection, poor perception of risk of infection, poor local availability of vaccines, and low uptake where same was available. Reasons cited for non-immunization are lack of awareness, cost, inertia and non-availability of vaccines. Only 10.2% of our respondents always used barrier methods, and 77.7% of our respondents do not check the immune status of their patients after sustaining an intraoperative sharp injury. The overall level of knowledge about HBV infection was deemed poor. We conclude with recommendations on how to improve knowledge about HBV infection and uptake of vaccines.
