Prevalence Of Sickle Haemoglobin And Glucose–6–Phosphate Dehydrogenase Deficiency Genes In The Populations Of North West And South West Provinces, Cameroon

Hereditary disorders of erythrocytes are common in many areas of the world, including Cameroon Limited knowledge on the consequences of high incidences of sickle haemoglobin (HbS) and glucose-6-phosphate dehydrogenase (G6PD) deficiency genes in the Cameroons might have been responsible for the haemoglobin genotype mismatched marriages among the sickle heterozygotes and drug-induced anaemia among the G6PD deficient individuals ignorantly treated wth oxidant drugs having high redox potential. The situation therefore, informed the random screening of the populace of the North West and South West populatons of Cameroon for these genes wth a view not only to reveal their current incidences and level of interaction but also to educate the people onthe consequences of these genetic defects. Our results revealed the total incidences of 32.20 % sickle and 1161 % G6PD deficiency genes. The percentage frequency of the sickle cell gene was higher in the South western (1880 %) than in the North West (1451 %) populations. The percentage incidence o G6PD deficiency was 921 % and 120 % for males and females respectvely in the North West and 10.85 % and 1.46 % for males and females respectively in the South West. The interaction was not sgnificant (P > 0.01) between G6PD deficiency and HbS for the North West and South West populatons. These genetic defects must have reached polymorphiclevels due to natural selection through survival advantage against death from malaria and consanguineous marriages.

The burden of high blood pressure and related risk factors in urban Sub-Saharan Africa: Evidences from Douala in Cameroon

Objective: To provide the current burden of high blood pressure and related risk factors in urban setting in Cameroon. Methods:We used the WHO STEPS approach for Surveillance of non-communicable diseases and their risk factors to collect data from 2,559 adults aged 15-99 years, residing at Cite des Palmiers in Douala, Cameroon. Results: The level of education was low with up to 60% of participants totalizing less than primary school. Smoking habits were 6 times more frequent in men (

Setting-up nurse-led pilot clinics for the management of non-communicable diseases at primary health care level in resource-limited settings of Africa

Background: This article describes the setting-up process for nurse-led pilot clinics for the management of four chronic diseases: asthma, type 2 diabetes mellitus, epilepsy and hypertension at the primary health care level in urban and rural Cameroon. Methods: The Biyem-Assi urban and the Bafut rural health districts in Cameroon served as settings for this study. International and local guidelines were identified and adapted to the country’s circumstances. Training and follow-up tools were developed and nurses trained by experienced physicians in the management of the four conditions. Basic diagnostic and follow-up materials were provided and relevant essential drugs made available. Results: Forty six nurses attended six training courses. By the second year of activity, three and four clinics were operational in the urban and the rural areas respectively. By then, 925 patients had been registered in the clinics. This represented a 68.5% increase from the first year. While the rural clinics relied mainly on essential drugs for their prescriptions, a prescription pattern combining generic and proprietary drugs was observed in the urban clinics. Conclusion: In the quest for cost-effective health care for NCD in sub-Saharan Africa, rethinking health workforce and service delivery has relevance. Nurse-led clinics, algorithm driven service delivery stands as alternatives to overcome the shortage of trained physicians and other issues relating to access to care

Introducing Misoprostol for the Treatment of Incomplete Abortion in Nigeria

Despite legal restriction, induced abortions and resulting complications are common in Nigeria. Misoprostol administration for incomplete abortion was introduced in 3 Nigerian hospitals. The feasibility of the hospitals, patient and provider acceptability were assessed using questionnaire and interview guides administered to 205 women and 17 providers respectively. Amongst the women, 194 (95%) were satisfied and very satisfied with misoprostol, 176 (86%) would choose misoprostol again if another incomplete abortion occurred and 191 (93%) would recommend it to another woman in a similar situation. Providers were highly satisfied with misoprostol. The ease of use and ability to redirect surgical resources to more complicated issues were positive features cited by them. The providers agreed that integration of misoprostol was straightforward and required few resources. Therefore, misoprostol for incomplete abortion is safe, efficacious and acceptable to providers and patients. In remote areas of Nigeria with limited post-abortion care (PAC), misoprostol administration is an important potential PAC treatment modality. Features of misoprostol-low cost, room temperature stability, and ease of introduction-render it an important treatment option, particularly in low resource and rural settings

Cure or control: complying with biomedical regime of diabetes in Cameroon

<p>Abstract</p> <p>Background</p> <p>The objective of the study was to explore the cultural aspect of compliance, its underlying principles and how these cultural aspects can be used to improve patient centred care for diabetes in Cameroon.</p> <p>Methods</p> <p>We used participant observation to collect data from a rural and an urban health district of Cameroon from June 2001 to June 2003. Patients were studied in their natural settings through daily interactions with them. The analysis was inductive and a continuous process from the early stages of fieldwork.</p> <p>Results</p> <p>The ethnography revealed a lack of basic knowledge about diabetes and diabetes risk factors amongst people with diabetes. The issue of compliance was identified as one of the main themes in the process of treating diabetes. Compliance emerged as part of the discourse of healthcare providers in clinics and filtered into the daily discourses of people with diabetes. The clinical encounters offered treatment packages that were socially inappropriate therefore rejected or modified for most of the time by people with diabetes. Compliance to biomedical therapy suffered a setback for four main reasons: dealing with competing regimes of treatment; coming to terms with biomedical treatment of diabetes; the cost of biomedical therapy; and the impact of AIDS on accepting weight loss as a lifestyle measure in prescription packages. People with diabetes had fears about and negative opinions of accepting certain prescriptions that they thought could interfere with their accustomed social image especially that which had to do with bridging their relationship with ancestors and losing weight in the era of HIV/AIDS.</p> <p>Conclusion</p> <p>The cultural pressures on patients are responsible for patients' partial acceptance of and adherence to prescriptions. Understanding the self-image of patients and their background cultures are vital ingredients to improve diabetes care in low-income countries of Sub-Sahara Africa like Cameroon.</p

Abattoir-based estimates of mycobacterial infections in Cameroon

Mycobacteria cause major diseases including human tuberculosis, bovine tuberculosis and Johne’s disease. In livestock, the dominant species is M. bovis causing bovine tuberculosis (bTB), a disease of global zoonotic importance. In this study, we estimated the prevalence of Mycobacteria in slaughter cattle in Cameroon. A total of 2,346 cattle were examined in a cross-sectional study at four abattoirs in Cameroon. Up to three lesions per animal were collected for further study and a retropharyngeal lymph node was collected from a random sample of non-lesioned animals. Samples were cultured on Lowenstein Jensen media and the BACTEC MGIT 960 system, and identified using the Hain® Genotype kits. A total of 207/2,346 cattle were identified with bTB-like lesions, representing 4.0% (45/1,129), 11.3% (106/935), 23.8% (38/160) and 14.8% (18/122) of the cattle in the Bamenda, Ngaoundere, Garoua and Maroua abattoirs respectively. The minimum estimated prevalence of M. bovis was 2.8% (1.9–3.9), 7.7% (6.1–9.6), 21.3% (15.2–28.4) and 13.1% (7.7–20.4) in the four abattoirs respectively. One M. tuberculosis and three M. bovis strains were recovered from non-lesioned animals. The high prevalence of M. bovis is of public health concern and limits the potential control options in this setting without a viable vaccine as an alternative

Understanding perceptions on 'Buruli' in northwestern Uganda: A biosocial investigation.

BACKGROUND: An understudied disease, little research thus far has explored responses to Buruli ulcer and quests for therapy from biosocial perspective, despite reports that people seek biomedical treatment too late. METHODS AND FINDINGS: Taking an inductive approach and drawing on long-term ethnographic fieldwork in 2013-14, this article presents perspectives on this affliction of people living and working along the River Nile in northwest Uganda. Little is known biomedically about its presence, yet 'Buruli', as it is known locally, was and is a significant affliction in this region. Establishing a biosocial history of 'Buruli', largely obscured from biomedical perspectives, offers explanations for contemporary understandings, perceptions and practices. CONCLUSIONS/SIGNIFICANCE: We must move beyond over-simplifying and problematising 'late presentation for treatment' in public health, rather, develop biosocial approaches to understanding quests for therapy that take into account historical and contemporary contexts of health, healing and illness. Seeking to understand the context in which healthcare decisions are made, a biosocial approach enables greater depth and breadth of insight into the complexities of global and local public health priorities such as Buruli ulcer

Isolation, Growth and Identification of Chlorpyrifos Degrading Bacteria from Agricultural Soil in Anambra State, Nigeria

Abstract The extensive use of pesticides is one of the major causes of pollution of soil and water environments. The current method for removing such contaminants from the environment through biodegradation has been shown to be more effective than any other method. Three pesticide degrading bacteria were isolated and identified through cultural and biochemical tests as strains of Pseudomonas aeruginosa, Serretia marcescens and Klebsiella oxytoca. Their growth in mineral salt medium supplemented with 20mg/l of Chlorpyrifos was monitored at optical density of 600nm. The result showed that Pseudomonas aeruginosa had maximum growth in ten days, while Serretia marcescens and Klebsiella oxytoca recorded highest growth after six days of incubation. HPLC analysis of the residual Chlorpyrifos after 14 days incubation showed that Pseudomonas aeruginosa was able to degrade 60% of the pesticide; Klebsiella oxytoca degraded 54%, while Serretia marcescens had 53% reduction of the pesticide concentration in the mineral salt medium. The results of this research indicated that the isolated bacteria can be used for bioremediation of Chlorpyrifos contaminated soil and water ecosystems
