Misconception on oxygen administration among patients and their caregivers in Ado Ekiti, Nigeria.

Introduction: Appropriate oxygen administration is a life-saving therapy; however, patients and their caregivers could decline such therapy for several reasons. Poor perceptions may delay consent to oxygen therapy. There is a lack of data on the perception of oxygen use among patients and caregivers in our setting. Hence, this study was aimed at evaluating the perception of patients and their caregivers toward emergency oxygen use in a tertiary hospital in Nigeria. Materials and Methods: This survey was a descriptive cross-sectional study conducted between December 2017 and May 2018 at a tertiary hospital in southwestern Nigeria. We administered a structured questionnaire to 334 eligible patients and their 539 caregivers while on admission. Results: A significant proportion of the patients compared to their caregivers have had oxygen therapy in the past 40.6% versus. 6.9% P < 0.0001. The majority of the participants (patients vs. caregivers 84.7% vs. 81.1% P = 0.511) believed oxygen therapy to be beneficial and safe for use (patients vs. caregivers 79.4% vs. 78.6%; P = 0.8949). However, 21.1% of patients and 19.5% of caregivers believed it is solely for terminally ill patients. More than 50% of patients and caregivers thought oxygen can cause adverse effects and fire outbreaks. Most of the respondents considered oxygen therapy as expensive (patients vs. caregivers; 78.2% vs. 87.2%; P = 0.0176) which was regarded as a possible barrier to treatment (patients vs. caregivers 81.9% vs. 85.0% P = 0.3893). <1% of both patients and their caregivers have had any form of training in basic life support. Conclusion: The misconceptions about oxygen use require urgent attention by raising community awareness and knowledge toward improving the acceptability of this life-saving intervention.

Résumé Introduction : L'administration appropriée d'oxygène est une thérapie salvatrice ; cependant, les patients et leurs soignants pourraient refuser une telle thérapie pour plusieurs raisons. De mauvaises perceptions peuvent retarder le consentement à l'oxygénothérapie. Il y a un manque de données sur la perception de l'utilisation d'oxygène chez les patients et soignants dans notre milieu. Ainsi, cette étude visait à évaluer la perception des patients et de leurs soignants face à l'urgence. utilisation d'oxygène dans un hôpital tertiaire au Nigeria. Matériels et méthodes : Cette enquête était une étude transversale descriptive menée entre décembre 2017 et mai 2018 dans un hôpital tertiaire du sud-ouest du Nigéria. Nous avons administré un questionnaire structuré à 334 patients éligibles et leurs 539 soignants lors de leur admission. Résultats : Une proportion significative des patients par rapport à leurs soignants ont reçu de l'oxygène thérapie dans le passé 40,6% versus. 6,9 % P < 0,0001. La majorité des participants (patients vs soignants 84,7% vs 81,1% P = 0,511) croyaient que l'oxygénothérapie était bénéfique et sans danger (patients vs soignants 79,4 % vs 78,6 % ; P = 0,8949). Cependant, 21,1 % des patients et 19,5 % des soignants pensaient que c'était uniquement pour les patients en phase terminale. Plus de 50 % des patients et des soignants pensaient que l'oxygène pouvait causer les effets néfastes et les départs de feu. La plupart des répondants considéraient l'oxygénothérapie comme coûteuse (patients vs soignants ; 78,2 % vs 87,2 % ; P = 0,0176) qui était considéré comme un obstacle possible au traitement (patients vs soignants 81,9 % vs 85,0 % P = 0,3893). <1 % des deux patients et leurs soignants ont suivi une formation de base en maintien de la vie. Conclusion : Les idées fausses sur l'utilisation de l'oxygène nécessitent une attention en augmentant la sensibilisation et les connaissances de la communauté en vue d'améliorer l'acceptabilité de cette intervention qui sauve des vies.

Sexual practices, risk perception and HIV self-testing acceptability among long-distance truck drivers in Ekiti State, Nigeria.

BACKGROUND: HIV/AIDS is a global health challenge with a high burden in sub-Saharan Africa. Long-distance drivers are a high-risk group whose assessment of HIV status, awareness and willingness to undergo HIV self-testing (HIVST) could help prevent the spread of HIV infections. OBJECTIVE: This study examined the sexual practices, risk perception and HIVST acceptability among long-distance truck drivers in Ekiti State, Nigeria. METHODS: A cross-sectional study was conducted among long-distance truck drivers between September 2019 and December 2019. A semi-structured questionnaire was designed to investigate the perceived sexual risk factors and willingness to undergo HIVST. RESULTS: Of the 306 drivers that participated in the study, almost half (49.8%) had their first sexual experience before they turned 18 years. About one-third (38.6%) had multiple sex partners and (34.0%) patronised commercial sex workers in the past 6 months. Consistent use of condoms was reported in a negligible percentage (3.0%), while 7.4% used intravenous drugs. Two-thirds of the respondents were interested in HIVST, while 32.2% knew their HIV status. Significant factors associated with multiple sex partners were the duration of working as a long-distance truck driver and patronage of sex workers. CONCLUSION: A significant proportion of the long-distance drivers were engaged in unsafe sexual practices and are at risk for HIV transmission. Considering the mobile nature of the long-distance drivers, the risky practices of these workers require intense advocacy, testing and treatment to reduce HIV transmission. Scaling-up testing using HIVST has the potential to bridge the gap in the diagnosis of HIV among long-distance drivers who are willing to be tested.

Diagnosis of latent tuberculosis among HIV infected patients in Ilorin, Nigeria using tuberculin skin test and interferon gamma release assay.

INTRODUCTION: Latent Tuberculosis Infection (LTBI) screening is recommended for individuals with a known risk factor for progression to active disease especially in the setting of HIV infection. This will ensure early diagnosis and prompt treatment. The purpose of our study was to compare tuberculin skin test (TST) with Interferon Gamma Release Assay (IGRA) in the diagnosis of LTBI among patients with known HIV infection at University of Ilorin Teaching Hospital (UITH), Ilorin. METHODS: this was a hospital based cross-sectional study at the Highly Active Antiretroviral therapy (HAART) Clinic and medical wards of the University of Ilorin Teaching Hospital, Ilorin, Nigeria. A total of 282 consenting patients with HIV infection were recruited. Sociodemographic and clinical information was obtained using a well-structured questionnaire. The screening for LTBI was done using Tuberculin skin test (TST) and Interferon Gamma release assay (IGRA). RESULTS: the prevalence of LTBI among HIV infected patients was 40.6% and 53.1% using TST and QFT-IT respectively, while the overall prevalence considering positivity to either of the test was 66%. There was mild agreement (κ: 0.218) between TST and QFT-IT in the diagnosis of LTBI among patients with HIV infection. The association between CD4 count and TST was not statistically significant (p value = 0.388) but there was strong association between CD4 cell count and QFT results (p = 0.001). CONCLUSION: the prevalence of LTBI is quite high among patients with HIV infection in our locality. There is a need to encourage screening of at-risk individuals to forestall the morbidity and mortality associated with TB in this population.

Spirometric abnormalities following treatment for pulmonary tuberculosis in Ilorin, Nigeria.

BACKGROUND: Pulmonary tuberculosis (PTB) contributes significantly to morbidity and mortality worldwide, and despite microbiological cure for the disease, many patients still demonstrate residual respiratory symptoms and spirometric abnormalities. AIM AND OBJECTIVES: The study aimed at identifying the prevalence, pattern and factors associated with spirometric abnormalities in patients successfully treated for PTB in Ilorin, Nigeria. MATERIALS AND METHODS: This was a hospital-based cross-sectional study at the pulmonary outpatient clinics of the University of Ilorin Teaching Hospital and Kwara State Specialist Hospital, Sobi, Ilorin. A total of 308 consenting patients who had been certified microbiologically cured for bacteriologically confirmed PTB in the preceding 3 years had assessment of residual pulmonary symptoms, spirometry and plain chest radiograph. RESULTS: The prevalence of abnormal spirometry following treatment for PTB was 72.1% (confidence interval: 0.6682-0.7695), with restrictive pattern being the predominant abnormality (42.2%). Over half of the patients (56.5%) had at least one residual respiratory symptom. The significant predictors of abnormal spirometry were PTB retreatment (adjusted odds ratio [aOR] = 6.918; P = 0.012), increasing modified Medical Research Council dyspnoea scores (aOR = 7.935; P = 0.008) and increasing radiologic scores (aOR = 4.679; P ≤ 0.001) after treatment. CONCLUSION: There is significant residual lung function impairment in majority of the individuals successfully treated for PTB in Ilorin. This highlights the need for spirometric assessment and follow-up after treatment.

Clinical and microbiological profile of adult inpatients with community acquired pneumonia in Ilorin, North Central, Nigeria.

BACKGROUND: The optimal management of community acquired pneumonia (CAP) depends on the clinical and microbiological profile in the locality. OBJECTIVES: To determine the clinical and microbiological profile of patients admitted with CAP in Ilorin, Nigeria. METHODS: One hundred and two consenting consecutively selected patients with clinical and radiologic confirmation of CAP were recruited in 12 months. The socio-demographic, physical examination and laboratory/radiologic parameters were documented in a questionnaire. Microbiological evaluation of their sputum was done and blood samples were taken for complete blood count, culture, serum urea and serological evaluation for atypical bacteria and some viral pathogens. RESULTS: CAP constituted 5.9% of the total medical admissions during the one-year study period. The mean age of the patients was 49 ± 22 years with the largest frequency in those aged 65 years and above. The commonest symptoms were shortness of breath (96.1%) and cough (94.1%), with a median duration of 3 days from symptom onset to admission. Systemic hypertension was the commonest comorbid illness (25/102; 24.5%). Klebsiella pneumoniae was the predominant pathogen isolated (20/102; 28.1%). The susceptible antibiotics were Imipenem, Ceftazidime and Ceftriaxone. Intra-hospital mortality was 17.6%. CURB - 65 score of ≥ 2 and the presence of complications of CAP were the independent predictors of mortality. CONCLUSION: CAP constitutes a significant disease burden in Ilorin, Nigeria. Typical bacteria accounted for over half of the pathogens isolated from the patients with gram negative agents predominating. This highlights a possible shift in the microbiological profile which could guide empirical treatment.

Etiology, clinical characteristics, and management of pleural effusion in Ilorin, Nigeria.

BACKGROUND: Pleural effusion (PE) is a primary manifestation or secondary complication of many disorders. This study reviews the pattern and management of PE in a Nigerian hospital. MATERIALS AND METHODS: The medical records of 213 patients with clinical diagnosis of PE over a period of 3 years were reviewed. RESULTS: PE accounted for 0.5% of the total hospital admissions. The most common cause of PE was tuberculosis (TB) (32.9%), followed by malignancy (29.1%) and pneumonia (15.0%). The male to female ratio was 1.3:1. TB was the leading cause of effusion in males, while it was malignancy in females. Pneumonia accounted for 61.9% of PE in preschool age and 66.7% in school age. Breathlessness (50.0%), cough (39.4%), and chest pain (24.9%) were the common presentations. Most (90.1%) of them were exudative effusion and with half in the right lung. Chest radiography (91.6%), pleural fluid for Ziehl-Neelsen stain (74.7%), cytology (59.2%), and tissue biopsy (57.8%) were the common diagnostic investigations. The majority (92.0%) had closed thoracostomy tube drainage, while 9.9% had chemical pleurodesis. The intra-hospital mortality was 10 (4.7%). CONCLUSION: TB, malignancy, and pneumonia are the leading causes of PE. A multidisciplinary approach is needed for optimal management.

Bronchoscopy in Nigerian Clinical Practice: A Survey of Medical Doctors' Perception, Use and Associated Challenges.

BACKGROUND: Bronchoscopy is a vital diagnostic and therapeutic procedure in pulmonological practice. The aim of this study was to determine the perception, use and challenges encountered by Nigerian medical doctors involved in this procedure. MATERIALS AND METHODS: A cross-sectional study was conducted among 250 medical doctors recruited from three major tertiary institutions in Nigeria between September 2013 and June 2014. A semi-structured questionnaire was self-administered to adult physicians, paediatricians, and surgeons as well as their trainees to obtain their perception, use and associated challenges in the use of bronchoscopy in clinical practice. RESULTS: The majority (91.6%) of the respondents perceived bronchoscopy as a beneficial procedure to respiratory medicine. However, 59.2% of them were not aware of the low mortality rate associated with this procedure. The commonest indications for bronchoscopic use were foreign body aspiration (88.8%) and management of lung tumors (75.6%). Only 21 (8.4%) of the respondents had received formal training in bronchoscopy. Very few procedures (1-5 cases per month) were performed. The respondents identified the lack of formal training in the art of bronchoscopy as the foremost challenge facing its practice in Nigeria. In addition, availability of bronchoscopes, level of awareness, knowledge of the procedure among medical doctors and the cost of the procedure were the challenges faced by the medical doctors. CONCLUSION: There is an urgent need to equip training centers with modern bronchoscopic facilities. In addition,well-structured bronchoscopic training programme is imperative to enhance the trainees' proficiency for the furtherance of bronchoscopic practice.

Novel Cardiovascular Risk Markers in Nigerian Cigarette Smokers.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of mortality and morbidity worldwide. While the effect of cigarette smoking on conventional markers that account for <50% of CVD s has been well studied, there are only a few studies on the effect of cigarette smoking on novel cardiovascular (CV) risk markers. OBJECTIVE: To evaluate the effect of cigarette smoking on the novel CV markers such as homocysteine (HCY), lipoprotein (a) (Lp(a)), and C-reactive protein (CRP). MATERIALS AND METHODS: One hundred and forty smokers, 12 ex-smokers, and 84 controls were recruited for the study. A structured questionnaire was used to obtain information on their clinical history, daily cigarette consumption, and duration of smoking. The smokers were further grouped according to the amount of cigarette consumption: light (<5 sticks/day), moderate (6-10 sticks/day), and heavy (>10 sticks/day) and duration of smoking: short (5-10 years), medium (11-20 years), and long (>20 years). HCY was determined by enzyme-linked immunosorbent assay method, and Lp(a) and CRP were determined spectrophotometrically. RESULTS: HCY, Lp(a), and CRP were significantly elevated in smokers when compared with control (P < 0.05) and they correlated with daily cigarette consumption and duration of smoking. Ex-smokers also exhibited a significant increase in HCY, Lp(a), and CRP level (P < 0.05) when compared with the control, but were significantly lower than the current smokers. CONCLUSION: There is a linear relationship between the intensity and duration of cigarette smoking and serum levels of all three novel risk CV markers. These findings suggest that these markers may be an important mechanism by which smoking promotes atherosclerosis.

Quality of acute asthma care in two tertiary hospitals in a state in South Western Nigeria: A report of clinical audit.

BACKGROUND: To audit the quality of acute asthma care in two tertiary hospitals in a state in the southwestern region of Nigeria and to compare the clinical practice against the recommendations of the Global Initiative for Asthma (GINA) guideline. PATIENTS AND METHODS: We carried out a retrospective analysis of 101 patients who presented with acute exacerbation of asthma to the hospital between November 2010 and October 2015. RESULTS: Majority of the cases were females (66.3%), <45 years of age (60.4%), and admitted in the wet season (64.4%). The median duration of hospital stay was 2 days (interquartile range; 1-3 days) and the mortality was 1.0%. At admission, 73 (72.3%) patients had their triggering factors documented and 33 (32.7%) had their severity assessed. Smoking status, medication adherence, serial oxygen saturation, and peak expiratory flow rate measurement were documented in less than half of the cases, respectively. Seventy-six (75.2%) patients had nebulized salbutamol, 89 (88.1%) had systemic corticosteroid, and 78 (77.2%) had within 1 h. On discharge, 68 (67.3%) patients were given follow-up appointment and 32 (31.7%) were reviewed within 30 days after discharge. Less than half were prescribed an inhaled corticosteroid (ICS), a self-management plan, or had their inhaler technique reviewed or controller medications adjusted. Overall, adherence to the GINA guideline was not satisfactory and was very poor among the medical officers. CONCLUSION: The quality of acute asthma care in our setting is not satisfactory, and there is a low level of compliance with most recommendations of asthma guidelines. This audit has implicated the need to address the non-performing areas and organizational issues to improve the quality of care.

Knowledge and use of asthma control measurement tools in the management of asthma: a survey of doctors working in family and internal medicine practice in Nigeria.

OBJECTIVE: To investigate the knowledge and use of asthma control measurement (ACM) tools in the management of asthma among doctors working in family and internal medicine practice in Nigeria. METHOD: A questionnaire based on the global initiative on asthma (GINA) guideline was self-administered by 194 doctors. It contains 12 test items on knowledge of ACM tools and its application. The knowledge score was obtained by adding the correct answers and classified as good if the score ≥ 9, satisfactory if score was 6-8 and poor if < 6. RESULTS: The overall doctors knowledge score of ACM tools was 4.49±2.14 (maximum of 12). Pulmonologists recorded the highest knowledge score of 10.75±1.85. The majority (69.6%) had poor knowledge score of ACM tools. Fifty (25.8%) assessed their patients' level of asthma control and 34(17.5%) at every visit. Thirty-nine (20.1%) used ACM tools in their consultation, 29 (15.0%) of them used GINA defined control while 10 (5.2 %) used asthma control test (ACT). The use of the tools was associated with pulmonologists, having attended CME within six months and graduated within five years prior to the survey. CONCLUSION: The results highlight the poor knowledge and use of ACM tools and the need to address the knowledge gap.

Prevalence of stroke in three semi-urban communities in middle-belt region of Nigeria: a door to door survey.

INTRODUCTION: The burden of stroke has been projected to increase for developing countries, but data are limited, especially in sub-Saharan Africa. This necessitated this study to determine the stroke prevalence in a semi urban community in middle-belt region of Nigeria. METHODS: A two-phase door-to-door study was performed in three semi-urban communities of Kwara state; in the first phase 12,992 residents were screened and probable stroke cases were identified by trained health care workers. In the second phase individuals adjudged to be positive for stroke were screened with a stroke-specific questionnaire and made to undergo a complete neurological examination by a neurologist. Stroke diagnosis was based on clinical evaluation using WHO criteria. RESULTS: Out of the numbers that were screened, 18 probable stroke cases were identified in the first stage, and of these, 17 fulfilled WHO criteria for stroke, giving a crude prevalence rate of 1.31/1000 population. The prevalence of stroke was higher among the males than the females (1.54/1000 vs. 1.08/1000) with a ratio 1.4: 1. Sixteen subjects (94.1%) had one or more risk factors for stroke. Uncontrolled systemic hypertension (82.4%) was the commonest risk factors for stroke followed by transient ischaemic attack (TIA) (41.2%). CONCLUSION: Stroke is a condition that is prevalent in our environment; especially in older adults and men. Uncontrolled systemic hypertension and previous transient ischaemic attacks were the commonest risk factors for stroke in our community.

A 3 year audit of adult epilepsy care in a Nigerian tertiary hospital (2011-2013).

BACKGROUND: Epilepsy audit provides positive feedback to physicians that could assist in improving the quality of health care services provided for patients. This study was carried out to evaluate care given to people with epilepsy with the aim of determining potentials for improvement. MATERIALS AND METHODS: Medical records of patients with uncomplicated epilepsy who have attended the neurology clinic at the University of Ilorin Teaching Hospital for not less 12 months between years 2011and 2013 were reviewed. RESULTS: A total of 125 patients were as evaluated; of which 64 (51%) were males and 61 (49%) were females. Their median age was 26 (21-40) years and median seizure duration of 9 (4-15) years. Close to 65% of the patients were below 30 years of age. Most patients (68%) were referred by general practitioners/family physicians. Generalized epilepsy was the predominant seizure type seen in 73 (58%) patients. Majority of patients (76%) were on antiepileptic drug (AED) monotherapy, and 28 (22%) were on two AEDs combination. Eighty-one patients (64%) used carbamazepine either singly (63%) or in combination (18%) at an average dose of 600 mg/day. The two other common AEDs used were: Sodium valproate (45%) and phenobarbitone (9%). Fifty-one patients (41%) had good seizure control (no seizure in preceding 1 year), 34 (27%) had partial control (<12 attacks/year) and 41 (36%) had poor control (>1 attack/month). Overall, 66 patients (48%) had their medication changed between 2 and 3 times in the course of treatment, and the most common reason was poor seizure control. Twenty-one (21%) did not comply with the use of given AED. CONCLUSIONS: Less than half of our patients had good epilepsy control. To improve on drug compliance attending physicians need to prescribe more of the relatively cheaper AED like the phenobarbitone and to optimize drug dosage before switching to another.

Guideline-based COPD management in a resource-limited setting - physicians' understanding, adherence and barriers: a cross-sectional survey of internal and family medicine hospital-based physicians in Nigeria.

BACKGROUND: Few data exist on the understanding and adherence to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines in resource-limited settings, which are mostly in sub-Saharan Africa. OBJECTIVES: To assess physicians' understanding, adherence, and barriers to implementation of GOLD guidelines in Nigeria. METHODS: A questionnaire based on the recommendations of the guidelines was self-administered by 156 physicians in departments of internal and family medicine in selected hospitals to assess physician understanding of the GOLD guidelines and barriers to its implementation. The medical records of patients with chronic obstructive pulmonary disease (COPD) were also reviewed to assess adherence to the guideline recommendations. RESULTS: The performance score of all physicians was 22.37±0.39 (range 0-38). Pulmonologists had the highest score (37.00±0.00) while medical officers had the lowest score (19.93±4.98) (F=10.16, df=5, p<0.001). Forty one percent of physicians knew the spirometric criteria for diagnosing COPD and 26.9% could assess the severity. In clinical practice, 32% of patients had brief smoking counselling despite 70% being smokers, 24% had spirometry and 18% had assessment of severity. Almost 60% of patients were on oral aminophylline, 72% were on an inhaled long-acting ß2-agonist and corticosteroid combination, 2% had pulmonary rehabilitation and no patients were vaccinated. Self-reported adherence to the COPD guidelines was 23.7%. Lack of familiarity (39.8%) was cited as the most common barrier to adherence to the guidelines. CONCLUSIONS: The understanding of GOLD guidelines is satisfactory among Nigerian doctors managing patients with COPD but the level of adherence is poor. Educational interventions are needed to improve the implementation of guideline-based management.

Unmet needs in asthma treatment in a resource-limited setting: findings from the survey of adult asthma patients and their physicians in Nigeria.

INTRODUCTION: The prevalence of asthma in our society is rising and there is need for better understanding of the asthma patients' perception and treatment practice of physicians. The study was aimed at determining asthma attitudes and treatment practices among adult physicians and patients in Nigeria, with the goal of identifying barriers to optimal management. METHODS: To assess asthma attitudes, treatment practices and limitations among adult physicians and patients in Nigeria, a questionnaire survey was conducted among 150 patients and 70 physicians. RESULTS: Majority (66.7%) of the patients reported their asthma as moderate to severe, 42.7% had emergency room visit and 32% had admission due to asthma in the previous 12 months. Physicians and patients perceptions significantly differed in the time devoted to educational issues (31.4% vs.18.7%) and its contents: individual management plan (64.3% vs.33.3%), correct inhaler technique (84.0% vs.71.0%), medication side effects (80.0% vs.60.0%) and compliance 100% of time (5.7% vs. 18.7%). Patients reported that non-compliance with medication causes increased symptoms (67.0%), exacerbations (60.0%), bronchodilator use (56.0%), urgent physician visit (52.0%) and hospitalizations /ER visits (38.7%). Asthma medication in patients caused short term (10.7%) and long term side effects (20.0%). Due to side effects, 28.0% skipped and stopped their medications. Most physicians (85.7%) and patients (56.0%) agreed on the need for new medication options. The need for new medication in patients was strongly related to asthma severity, limitation of activities, side effects, cost and lack of satisfaction with current medication. With the exception of pulmonologists, physicians did not readily prescribe ICS and their prescriptions were not in line with treatment guidelines. CONCLUSION: This study has highlighted the gaps and barriers to asthma treatment which need to be addressed to improve the quality of care in Nigeria.

Advanced sickle cell associated interstitial lung disease presenting with cor pulmonale in a Nigerian.

Previous studies have reported abnormal pulmonary function and pulmonary hypertension among Nigerians with sickle cell disease, but there is no report of interstitial lung disease among them. We report a Nigerian sickle cell patient who presented with computed tomography proven interstitial lung disease complicated by pulmonary hypertension and cor pulmonale.

A community survey of the pattern and determinants of household sources of energy for cooking in rural and urban south western, Nigeria.

INTRODUCTION: The use of solid fuels for cooking is associated with indoor pollution and lung diseases. The objective of the study was to determine the pattern and determinants of household sources of energy for cooking in rural and urban South Western, Nigeria. METHODS: We conducted a cross sectional study of households in urban (Ado-Ekiti) and rural (Ido-Ekiti) local council areas from April to July 2010. Female respondents in the households were interviewed by trained interviewers using a semi-structured questionnaire. RESULTS: A total of 670 households participated in the study. Majority of rural dwellers used single source of energy for cooking (55.6%) and urban dwellers used multiple source of energy (57.8%). Solid fuel use (SFU) was higher in rural (29.6%) than in urban areas (21.7%). Kerosene was the most common primary source of energy for cooking in both urban and rural areas (59.0% vs.66.6%) followed by gas (17.8%) and charcoal (6.6%) in the urban areas, and firewood (21.6%) and charcoal (7.1%) in the rural areas. The use of solid fuel was strongly associated with lack of ownership of dwellings and larger household size in urban areas, and lower level of education and lower level of wealth in the rural areas. Kerosene was associated with higher level of husband education and modern housing in urban areas and younger age and indoor cooking in rural areas. Gas was associated with high income and modern housing in the urban areas and high level of wealth in rural areas. Electricity was associated with high level of education, availability of electricity and old age in urban and rural areas respectively. CONCLUSION: The use of solid fuel is high in rural areas, there is a need to reduce poverty and improve the use of cleaner source of cooking energy particularly in rural areas and improve lung health.

Pattern of respiratory diseases seen among adults in an emergency room in a resource-poor nation health facility.

INTRODUCTION: There is a paucity of information on utilisation of emergency medical services in Nigeria. This study was conducted to determine the pattern of respiratory diseases seen among adults in an emergency room(ER) and their mortality within twenty- four hours in a health facility in Nigeria. METHODS: We carried out a retrospective study on adult patients that presented with respiratory condition from November 2004 to December 2010 at the emergency room of Federal Medical Centre Ido-Ekiti, south western, Nigeria. RESULTS: A total of 3671 cases were seen, 368 were respiratory cases accounting for 10.2 % of the total emergency room visitations. The male to female patients ratio was 1.2:1 and their mean was 49 9 ± 20.3 years. Pneumonia (34.5%) was the most common cases seen in the ER, followed PTB (29.4%), acute asthma (24.5%) , acute exacerbation of COPD (10.3%), upper airway tract obstruction and malignant pleural effusion were 0.5% respectively. Fourteen of the PTB cases (3.8%) were complicated by cor-pulmonale, 9(2.5%) by pleural effusion, 4(1.1%) by massive haemoptysis and 2(0.5%) by pneumothorax. Twenty-four hours mortality was 7.4% and 44.4% of the death was due to PTB, 37.0% was due to pneumonia and 14.8% due to acute asthma attack. The overall mortalities also had a bimodal age group distribution as the highest death was recorded in ages 30-39 and ≥ 70 years. CONCLUSION: Pneumonia and PTB were the leading respiratory diseases among adults causing of emergency room visit and early mortality in this health facility in Nigeria.

Asthma in Nigeria: are the facilities and resources available to support internationally endorsed standards of care?

OBJECTIVE: The objective of this study was to assess the facilities and resources available to support internationally endorsed standards of asthma care at tertiary hospitals (University teaching, Federal Medical Centre and State specialist Hospitals) in Nigeria. METHODS: This cross sectional study was conducted among 68 tertiary hospitals (TH) in Nigeria from June 2009 to December 2009. Structured standards of care questionnaires on asthma based on the Global initiative for asthma (GINA) guideline were completed by physician working in each of the TH. RESULTS: Most TH lacked the services of respiratory physicians, internists, and pediatricians. Available basic infrastructures were asthma clinics (0%), clinic registers (20.6%), and hospital protocol (17.6%), doctor's attendance of asthma CME (8.8%) and nurse educator with a bias for asthma (14.7%). Thirty eight percent of TH had peak flow meter, 29.4% had spirometer, skin allergy test kits (15.6%), pulse oximeter (38.2%) while 17.6% had arterial blood gases analyser. Nebuliser and spacer were available in 41.2% and 20.6% of TH respectively. Oral short acting beta 2 agonist (SABA) was available in 79.4% of the hospitals, glucocorticosteroid (79.4%), theophyllines (76.5%), and SABA (metered-dose inhaler MDI: 76.5%, Nebules: 35.3%). Long acting beta 2 agonist (LABA) and steroid fixed dose combination inhaler (50%) was available in 50% of TH. Glucocorticosteroid nasal spray was available in 33.3% of TH and <10% reported the availability of anti-cholinergic and chromoglycate inhaler and oral leukotriene antagonist. Standard oxygen delivery system and self-educational support materials were available in 52.9% of TH. CONCLUSION: The available facilities and human resources for asthma management in Nigerian tertiary hospitals were not enough to support the standard internationally endorsed for asthma care. Provisions of deficient infrastructures and continuous training of health care personnel in asthma management are imperative to enhance the quality of care.

Increased risk of respiratory symptoms and chronic bronchitis in women using biomass fuels in Nigeria.

OBJECTIVE: To determine whether respiratory symptoms and chronic bronchitis are associated with the use of biomass fuels (BMFs) among women residing in rural areas of the Ekiti State, in southwestern Nigeria. METHODS: From January to June of 2009, we carried out a cross-sectional study including 269 adult women. To collect data on sociodemographic status, type of fuel used for cooking in the household, respiratory symptoms, and smoking history, we used a questionnaire adapted from the European Community Respiratory Health Survey. All of the participants were invited to undergo spirometry. RESULTS: Of the 269 women in the study, 161 (59.9%) used BMFs for cooking. The proportion of women who reported respiratory symptoms was greater among those using BMFs than among those using a non-BMF-cough (13.7% vs. 3.7%); wheezing (8.7% vs. 2.8%); chest pain (7.5% vs. 1.9%); breathlessness (11.8% vs. 6.5%); nasal symptoms (9.3% vs. 4.6%); and chronic bronchitis (10.6% vs. 2.8%). Multivariate logistic regression analysis revealed that the use of BMFs was associated with the following variables: cough (OR = 4.82; p = 0.01); chronic bronchitis (OR = 3.75; p = 0.04); wheezing (OR = 2.22; p = 0.23); chest pain (OR = 3.82; p = 0.09); breathlessness (OR = 1.54; p = 0.35); and nasal symptoms (OR = 2.32; p = 0.20). All of the spirometric parameters evaluated (FEV1, FVC, FEV1/FVC ratio, and PEF) were lower in the women using BMFs than in those using a non-BMF. CONCLUSIONS: Our results underscore the need for women using BMFs in their households to replace them with a nontoxic type of fuel, such as electricity or gas.

Risco aumentado de sintomas respiratórios e bronquite crônica em mulheres que utilizam biocombustíveis na Nigéria / Increased risk of respiratory symptoms and chronic bronchitis in women using biomass fuels in Nigeria

OBJETIVO: Determinar a associação de sintomas respiratórios e bronquite crônica com o uso de biocombustíveis entre mulheres habitantes de áreas rurais do estado de Ekiti, sudoeste da Nigéria. MÉTODOS: De janeiro a junho de 2009, realizou-se um estudo transversal com uma amostra de 269 mulheres adultas. Um questionário adaptado do European Community Respiratory Health Survey foi aplicado para a obtenção de dados sobre características sociodemográficas, tipo de combustível utilizado para a preparação de alimentos, sintomas respiratórios e história de tabagismo. Todas as participantes foram convidadas a realizar espirometria. RESULTADOS: Das 269 mulheres no estudo, 161 (59,9 por cento) utilizavam biocombustíveis para a preparação de alimentos. As mulheres que utilizavam biocombustíveis relataram mais sintomas respiratórios que aquelas que não os utilizavam - tosse (13,7 por cento vs. 3,7 por cento); sibilância (8,7 por cento vs. 2,8 por cento); dor no peito (7,5 por cento vs. 1,9 por cento); falta de ar (11,8 por cento vs. 6,5 por cento); sintomas nasais (9,3 por cento vs. 4,6 por cento); e bronquite crônica (10,6 por cento vs. 2,8 por cento). A análise multivariada por regressão logística confirmou que o uso de biocombustíveis está associado às seguintes variáveis: tosse (OR = 4,82; p = 0,01); bronquite crônica (OR = 3,75; p = 0,04); sibilância (OR = 2,22; p = 0,23); dor no peito (OR = 3,82; p = 0,09); falta de ar (OR = 1,54; p = 0,35); e sintomas nasais (OR = 2,32; p = 0,20). Todos os parâmetros espirométricos avaliados (VEF1, CVF, VEF1/CVF e PFE) foram menores nas mulheres que utilizavam biocombustíveis do que naquelas que não os utilizavam. CONCLUSÕES: Nossos resultados enfatizam a necessidade de se substituir o uso de biocombustíveis nos domicílios pelo de um tipo de combustível atóxico, como eletricidade ou gás.

OBJECTIVE: To determine whether respiratory symptoms and chronic bronchitis are associated with the use of biomass fuels (BMFs) among women residing in rural areas of the Ekiti State, in southwestern Nigeria. METHODS: From January to June of 2009, we carried out a cross-sectional study including 269 adult women. To collect data on sociodemographic status, type of fuel used for cooking in the household, respiratory symptoms, and smoking history, we used a questionnaire adapted from the European Community Respiratory Health Survey.
