Large hemorrhagic pericardial effusion with cardiac tamponade in a 16-year-old adolescent in an endemic area of tuberculosis: a case report
Pericardial effusion complicated by cardiac tamponade is a medical emergency. Large pericardial effusion and tamponade are rare in childhood. Tuberculosis remains a major cause of pericardial effusion in endemic areas. A 16-year-old adolescent with no significant past history was admitted to the medical unit of the Buea Regional hospital in the South West region of Cameroon for heart failure after presenting with abdominal distension, shortness of breath and fever of two weeks duration. Echocardiographic study during admission revealed a large pericardial effusion (27mm in thickness) with echocardiographic signs of tamponade. Echocardiographic guided pericardiocentesis was performed through a sub-xiphoid route and about 500 cc of heavily stained blood fluid that was not coagulating was drained. Pericardial fluid analysis for acid fast bacilli was negative. There was no evidence of malignancy. A strong suspicion of tuberculosis was made and he was started on anti-tuberculosis medications for presumptive hemorrhagic tuberculous pericarditis. Patient was asymptomatic during follow up and repeat echocardiographic examinations showed no re-accumulation of pericardial fluid. Tuberculosis should be considered as the etiology of pericardial effusion in endemic areas although the identification of mycobacterium is challenging in these settings
Epidemiology of cardiovascular diseases related admissions in a referral hospital in the South West region of Cameroon: A cross-sectional study in sub-Saharan Africa.
BackgroundSub-Saharan Africa (SSA) is experiencing an epidemic of cardiovascular diseases (CVD) as a result of a rapid epidemiological transition. Little is known about the admission for CVD and outcome in rural and semi-urban settings in Cameroon in this era of epidemiological transition. The aim of this study was to determine the frequency and the pattern of CVD admissions in the South West region of Cameroon.MethodsThis retrospective descriptive study included all adult patients admitted for CVD in the medical unit of the Buea Regional Hospital between Jan 2016 and December 2017.ResultsOut of the 3140 patients admitted, 499(15.9%) had CVD. There were 304(60.9%) females. The mean age was 58.7±16.2 years. There was no age difference between men and women (59.7 years vs 58.1years, p = 0.29). The most commonly affected age group was those aged 50-59 years (22%). Heart failure (38.5%), stroke (33.3%) and uncontrolled hypertension (22.4%) were the most prevalent CVDs. The length of hospital stay ranged from 1 to 37 days with a median length of hospital stay of 7 days. In-hospital case fatality was 78(15.8%). Mortality was higher in women compared to men (9% vs 7%, p = 0.43). The case fatality for stroke was higher compared to case fatality for heart failure (21.7% vs 16.7%, p = 0.23).ConclusionCVDs are a common cause of hospital admission in this semi-urban setting, dominated by heart failure. Women were disproportionately affected and it was associated with high mortality. Prevention, early detection and management of risk factors for cardiovascular disease are imperative given the growing burden of CVD in SSA to reduce CVD morbidity and mortality
Rheumatic heart disease in the South West region of Cameroon: A hospital based echocardiographic study
Objective: Rheumatic heart disease (RHD) prevails as a major public health problem in sub-Saharan Africa. In Cameroon, reports on RHD have been so far limited to a few cities. We sought to describe the demographic, clinical and echocardiographic features of rheumatic heart disease in the Buea Regional Hospital, South West region of Cameroon. Echocardiography reports between June 2016 and June 2017 were reviewed. The diagnosis of RHD was based on the World Heart Federation Criteria for the diagnosis of RHD. Results: A total of 669 echocardiograms were performed over the 1 year study period. Twenty-one (3.1%) had a definite echocardiographic diagnosis of RHD. There were 14 (66.7%) females. The age range was 13-94 years with a mean age of 47.8 ± 20.3 years. The most common indications for echocardiography were heart failure (47.6%), and dyspnea (42.9%). The mitral valve was the most commonly affected valve in 80.9% of cases. The most common valve lesion was isolated mitral stenosis (42.9%), followed by isolated mitral regurgitation (28.6%). There were no lesions on the tricuspid and pulmonic valves. Severe lesions were found in 80.9% of the patients. The complications were pulmonary hypertension (66.7%) and atrial fibrillation (9.5%)
Rheumatic heart disease awareness in the South West region of Cameroon: A hospital based survey in a Sub-Saharan African setting.
BACKGROUND:Early diagnosis and adequate treatment of Group A streptococcal throat infection is an important initial stage in the primary prevention of acute rheumatic fever and rheumatic heart disease. This preventable condition associated with high mortality rates mandates a thorough understanding by the general public and the health. OBJECTIVE:The aim of the study was to assess the level of awareness about different aspects of rheumatic heart disease in patients coming to the outpatient department of the Buea regional Hospital, South West region of Cameroon. METHODS:This was a cross-sectional descriptive study carried in the outpatient department of the Buea Regional Hospital, Cameroon. The study population was adults and children aged 9 years and above. Data collection was done by using a self-administered questionnaire addressed to assess awareness on rheumatic heart disease. RESULTS:A total of 256 participants were interviewed, of which 70 (27.3%) were males. Their mean age was 34.4 ± 11.9 years (males: 36.2 ± 12.7 years versus females: 33.7 ± 11.6 years, p = 0.129). Most of the participants were in the 20 to 29 year old group (37.9%). More than two thirds (71.1%) of the participants reported having had sore throat at least once. The disease was treated with antibiotics in only 45.4%, with the treatment prescribed by a health care professional in 35.8% of the cases. About 73% of the respondents did not know what causes sore throat, and most (71.1%) were unaware of any complications that could arise from poorly treated sore throat. More than 70% of the participants did not know that sore throat can be associated with heart disease. Rheumatic heart disease was unknown to 82% of the participants and 95% of them did not know what causes RHD. Only 5.1% percent of the participants had an adequate knowledge of RHD. Age ≤ 35 years, post-secondary level of education, and having heard of RHD were significantly associated with an adequate knowledge. After adjusting for age, post-secondary education (aOR: 9, [95% C: 1.2-67.5], p = 0.019), and having heard of RHD (aOR: 18.1, [95% CI: 4.7-70.3], p<0.001) were still associated with a fair knowledge. CONCLUSIONS:Levels of knowledge and awareness on rheumatic heart disease is low. This study provides important insight into the perception and practices related to sore throat that can be used in the design of awareness activities aimed reducing the risk of RHD in Cameroon. The appropriateness of antibiotics prescribed, and the health care provider awareness and knowledge levels regarding RHD in Cameroon has not been reported yet in the literature. This grey area deserves more research
A predominance of hypertensive heart disease among patients with cardiac disease in Buea, a semi-urban setting, South West Region of Cameroon
Abstract Objective The pattern of heart disease is diverse within and among world regions. The little data on the spectrum of heart disease in Cameroon has been so far limited to major cities. We sought to describe the pattern of heart disease in Buea, the South West Region of Cameroon, a semi-urban setting. This was a descriptive cross-sectional study. Between June 2016 and April 2017 the echocardiography register of the Buea Regional Hospital was surveyed. We extracted data on the age, sex and echocardiographic diagnosis. Results Out of 529 patients who underwent echocardiography, 239 (45.2%) had a definite heart disease. There were 137 (57.3%) females. The mean age was 58 years (range 3–94 years). The most common echocardiographic diagnoses were hypertensive heart disease (43.2%), dilated cardiomyopathies (17.6%), ischemic heart diseases (9.6%), and cor pulmonale (8.8%). Rheumatic heart disease affected 6.7% of the patients. The most common rheumatic heart disease was mitral stenosis followed by mitral regurgitation. Congenital heart disease represented 2.1% and 5 patients (2.1%) had pulmonary hypertension. Hypertensive heart disease is the most common cardiac disease in this semi-urban region in Cameroon. Rheumatic heart disease still affects a sizable proportion of patients. Prevention of cardiac disease in our setting should focus on mass screening, the treatment and control of hypertension
Profile and outcomes of patients admitted with hyperglycemic emergencies in the buea regional hospital in Cameroon
Introduction: hyperglycemic emergencies (diabetic ketoacidosis and hyperglycemic hyperosmolar state) are the most common serious acute metabolic complications of diabetes which result in significant morbidity and mortality. There is paucity of data on hyperglycemic emergencies in Cameroon. The objective of this study was to investigate the precipitants and outcomes of patients admitted for hyperglycemic emergencies in the Buea Regional Hospital in the South West Region of Cameroon. Methods: in this retrospective study the medical records of patients admitted for hyperglycemic emergencies between 2013 and 2016 in the medical unit of the Buea Regional Hospital were reviewed. We extracted data on demographic characteristics, admission clinical characteristics, precipitants, and treatment outcomes. Logistic regression was used to determine predictors of mortality. Results: data were available for 60 patients (51.7% females) admitted for hyperglycemic emergencies. The mean age was 55.2±16.3 (range 18-86). Overall there were 51 (85%) cases of hyperosmolar hyperglycemic state. Twenty six (43.3%) of the patients had hypertension. The most common precipitants of hyperglycemic emergencies were infections (41.7%), newly diagnosed diabetes (33.3%) and non-adherence to medications (33.3%). Mean admission blood glucose was 574mg/dl±70.0mg/dl. The median length of hospital stay was 6 days. Overall case fatality rate was 21.7%. Six (46.2%) deaths were related to infections. Predictors of mortality were a Glasgow coma score 90(0.057) on admission. Conclusion: admission for hyperglycemic emergencies in this semi-urban hospital is associated with abnormally high case fatality. Infections, newly diagnosed diabetes and non-adherence to medications are the commonest precipitants of hyperglycemic emergencies. Public health measures to reduce morbidity and mortality from hyperglycemic crisis are urgently needed
