Epidemiology of paediatric surgical admissions to a government referral hospital in the Gambia

INTRODUCTION: There is a paucity of published data on the type of conditions that require surgery among children in sub-Saharan Africa. Such information is necessary for assessing the impact of such conditions on child health and for setting priorities to improve paediatric surgical care. METHODS: Described in the article is a 29-month prospective study of all children aged < 15 years who were admitted to a government referral hospital in the Gambia from January 1996 to May 1998. RESULTS: A total of 1726 children were admitted with surgical problems. Surgical patients accounted for 11.3% of paediatric admissions and 34,625 total inpatient days. The most common admission diagnoses were injuries (46.9%), congenital anomalies (24.3%), and infections requiring surgery (14.5%). The diagnoses that accounted for the greatest number of inpatient days were burns (18.8%), osteomyelitis (15.4%), fractures (12.7%), soft tissue injuries (3.9%), and head injuries (3.4%). Gambian children were rarely admitted for appendicitis and never admitted for hypertrophic pyloric stenosis. The leading causes of surgical deaths were burns, congenital anomalies, and injuries other than burns. DISCUSSION: Prevention of childhood injuries and better trauma management, especially at the primary and secondary health care levels, should be the priorities for improving paediatric surgical care in sub-Saharan Africa. Surgical care of children should be considered an essential component of child health programmes in developing countries.

Optimizing functional exercise capacity in the elderly surgical population

PURPOSE OF REVIEW: There are several studies on the effect of exercise post surgery (rehabilitation), but few studies have looked at augmenting functional capacity prior to surgical admission (prehabilitation). A programme of prehabilitation is proposed in order to enhance functional exercise capacity in elderly patients with the intent to minimize the postoperative morbidity and accelerate postsurgical recovery. RECENT FINDINGS: Few studies have looked at exercise prehabilitation to improve functional capacity prior to surgical admission. Prehabilitation prior to orthopaedic surgery does not seem to improve quality of life or recovery. However, prehabilitation prior to abdominal or cardiac surgery, based on 275 elderly patients, results in fewer postoperative complications, shorter postoperative length of stay, improved quality of life, and reduced declines in functional disability compared to sedentary controls. SUMMARY: A concentrated 3-month progressive exercise prehabilitation programme consisting of aerobic training at 45-65% of maximal heart rate reserve (%HRR) along with periodic high-intensity interval training ( approximately 90% HRR) four times per week, 30-50 minutes per session, is recommended for improving cardiovascular functioning. A strength training programme of about 10 different exercises focused on large, multi-jointed muscle groups should also be implemented twice per week at a mean training intensity of 80% of one-repetition maximum. Finally, a minimum of 140 g ( approximately 560 kcal) of carbohydrate (CHO) should be taken 3 h before training to increase liver and muscle glycogen stores and a minimum of about 200 kcal of mixed protein-CHO should be ingested within 30 min following training to enhance muscle hypertrophy.     

Emergency admission of patients to general surgical beds: attitudes of general practitioners, surgical trainees, and consultants in Liverpool, UK.

OBJECTIVES: To determine (a) whether doctors involved in the process of emergency surgical admission could agree about which patients should be admitted, (b) whether there were consistent differences between doctors in different specialty groups, and (c) whether these opinions were greatly influenced by non-clinical factors. DESIGN: Independent assessment of summarised case histories by three "expert" clinicians (two consultant surgeons and one general practitioner (GP)), by a group of 10 GPs, and by a group of 10 junior and senior surgeons. Experts, but not other observers, scored admissions both independently and as a consensus group. Observers indicated for each patient whether they would admit, would not admit, or were unsure. SETTING: An urban general hospital with teaching status. SUBJECTS: Fifty consecutive patients admitted to the general surgical unit as emergencies during 1995. MAIN OUTCOME MEASURES: Proportion of admissions considered unnecessary or uncertain: agreement between observers on these proportions: effect of social and procedural factors on the admission decision. RESULTS: Between 8 and 34% of admissions were considered unnecessary and 20-38% of unclear necessity. Agreement between the groups of clinicians was not good. GPs and consultant surgeons showed the poorest agreement (kappa = 0.08 to 0.25, 4 comparisons), and the GPs scored a higher percentage of admissions as unnecessary (34 v 8-12%). After discussion, the consensus group achieved good to very good agreement (kappa 0.61-0.84). CONCLUSIONS: Different groups of doctors vary widely in their views about the need for emergency surgical admission. Good agreement can be reached by consensus discussion. GPs are less likely than surgeons to consider emergency surgical admission necessary.     

Plasmid content, auxotype and protein-I serovar of gonococci isolated in the Gambia

Twenty-nine strains of penicillinase-producing Neisseria gonorrhoeae (PPNG) and 30 non-penicillinase-producing strains, all isolated in the Gambia, were characterized in terms of their plasmid content, auxotype and protein-I serovar. Sixty-two per cent of the PPNG strains contained the 3.2 MDa penicillinase-coding plasmid, and 38% had the 4.4 MDa plasmid. All the PPNG strains contained the 2.6 MDa cryptic plasmid but lacked the 24.4 MDa conjugative plasmid. In contrast, 46.7% of the non-PPNG strains harboured only the cryptic plasmid while 16.7% contained both the cryptic and conjugative plasmids. Seventeen per cent of the non-PPNG strains contained the conjugative plasmid only and 20% lacked plasmids. The PPNG and non-PPNG strains also differed in terms of their protein-I serovar. Eighty-six per cent of the PPNG strains belonged to serogroup 1 A, whereas the majority (60%) of non-PPNG strains belonged to serogroup 1 B. There was no significant difference in the auxotypes of the PPNG and non-PPNG strains, with both groups consisting predominantly of prototrophic and proline-requiring strains, with a minority of strains requiring arginine. When the 59 strains were each characterized in terms of their combined plasmid profile, auxotype and serovar, 39 different combinations were noted, which indicates the heterogeneous nature of the gonococcal population found in the Gambia.     

Separate lives, different interests: male and female reproduction in the Gambia

We report the initial findings of a research programme on the fertility and reproductive health of both men and women in rural Gambia. The reproductive experiences of men and women in the population studied were very different. During the period 1993-97, the total fertility rates were 12.0 for men and 6.8 for women. For men fertility began later, reached higher levels and continued into older ages than for women. Through serial and polygynous marriages, men were able to extend their reproduction beyond what would be possible with one woman. Of the married men interviewed, 40% were married polygynously. Men's fertility preferences indicated that they recognized their reproductive potentials to be greater than those of their individual wives. On average, married men desired 15.2 children for themselves and 7.3 for each wife. In this polygynous population the means available for attaining reproductive goals were different for the two sexes, depending on the separate lives and different interests of men and women.     

Therapeutic landscapes of the Jola, The Gambia, West Africa

This paper contributes to the 'new' medical geography through its analysis of the therapeutic landscapes of the Jola of The Gambia. The paper advances the debate surrounding the conceptualization of medicine and health through a review of literature on African medicinal systems; it examines in detail the health care system of the Jola of The Gambia, documenting indigenous human and ethnoveterinary medical beliefs and practices and focusing in particular on the role of herbal medicine; and it discusses the interactions and links between indigenous medicine and biomedicine, thus demonstrating the importance of placing an understanding of health care systems in different places within an awareness of global power relations. The paper therefore links cultural perspectives with a political economy analysis, to highlight the importance of place and specificity of cultural context when investigating health care beliefs and practices. The intention of the paper is to present a theoretically informed empirical case study which reinforces the practical value of a 'new' medical geography.     

Malnutrition and gastroenteritis in The Gambia

There is a strong association between failure to thrive and diarrhoeal disease in young Gambian children.The high prevalence of diarrhoeal disease seen is not due to frequent attacks of “acute infantile diarrhoea” of viral origin. The picture of protracted diarrhoea is almost certainly due to colonization of the upper bowel and the high prevalence demonstrated to be at least partly due to the environment to which the children are exposed, particularly in terms of food and water hygiene.Until this cycle of upper bowel colonization and protracted diarrhoea is broken, a diet-based nutrition programme cannot be expected to function effectively.

A tuberculosis nationwide prevalence survey in Gambia, 2012

ObjectiveTo estimate the population prevalence of active pulmonary tuberculosis in Gambia.MethodsBetween December 2011 and January 2013, people aged ≥ 15 years participating in a nationwide, multistage cluster survey were screened for active pulmonary tuberculosis with chest radiography and for tuberculosis symptoms. For diagnostic confirmation, sputum samples were collected from those whose screening were positive and subjected to fluorescence microscopy and liquid tuberculosis cultures. Multiple imputation and inverse probability weighting were used to estimate tuberculosis prevalence.FindingsOf 100 678 people enumerated, 55 832 were eligible to participate and 43 100 (77.2%) of those participated. A majority of participants (42 942; 99.6%) were successfully screened for symptoms and by chest X-ray. Only 5948 (13.8%) were eligible for sputum examination, yielding 43 bacteriologically confirmed, 28 definite smear-positive and six probable smear-positive tuberculosis cases. Chest X-ray identified more tuberculosis cases (58/69) than did symptoms alone (43/71). The estimated prevalence of smear-positive and bacteriologically confirmed pulmonary tuberculosis were 90 (95% confidence interval, CI: 53–127) and 212 (95% CI: 152–272) per 100 000 population, respectively. Tuberculosis prevalence was higher in males (333; 95% CI: 233–433) and in the 35–54 year age group (355; 95% CI: 219–490).ConclusionThe burden of tuberculosis remains high in Gambia but lower than earlier estimates of 490 per 100 000 population in 2010. Less than half of all cases would have been identified based on smear microscopy results alone. Successful control efforts will require interventions targeting men, increased access to radiography and more accurate, rapid diagnostic tests.     

Hepatitis associated antigen, cirrhosis and primary carcinoma of the liver in the Gambia.

45% of 65 Gambian patients with cirrhosis, and 53% of 63 patients with primary liver cancer were found to have hepatitis-associated antigenaemia, re-inforcing the possible aetiological role of hepatitis in these two common diseases of Africa.
