Outpatient burden of adult respiratory diseases in University of Ilorin Teaching Hospital, Nigeria.

Background: Respiratory diseases constitute a significant cause of morbidity globally. There is limited information on the epidemiology of respiratory diseases in North Central Nigeria particularly with the changing trend in risk factors. Aim: This study aimed at evaluating the pattern and morbidity related to respiratory diseases among adult outpatients attending a chest clinic in a tertiary healthcare facility, especially with increasing environmental pollution and biomass exposure globally. Patients And Methods: This was a retrospective review of the case records of 338 newly referred patients seen in the chest clinic of the University of Ilorin Teaching Hospital (UITH) with respiratory illnesses over a 2-year period (January 2017-December 2018). Results: The mean age of the recruited patients was 47.6 ± 19.8 years with a male to female ratio of 1.1:1. Microbiologically confirmed tuberculosis (30.2%), chronic obstructive pulmonary disease (COPD) (24.3%), and bronchial asthma (17.8%) were the commonest conditions managed in the clinic. Overall, noncommunicable respiratory diseases (61.2%) constituted a larger proportion of cases when compared to infective respiratory conditions. Almost 90% of the patients were never smokers. Systemic hypertension (15.1%) and human immunodeficiency virus infection (3.6%) were the commonest comorbid illnesses. Conclusion: Although tuberculosis constituted the most observed single condition, noncommunicable respiratory diseases predominated cumulatively among the new cases seen in the chest clinic of UITH, Ilorin. This raises the need for significant attention in terms of prevention and management of noncommunicable respiratory diseases, which appear to be on the uprising.

Assessment of Post-Treatment Health-Related Quality of Life among Patients with Pulmonary Tuberculosis in Ilorin, Nigeria.

BACKGROUND: A lot of attention has generally been given to the microbiology and treatment of pulmonary tuberculosis with relatively limited consideration on its impact on the physical, psychological and social domains of the individual especially after successful drug treatment. AIM AND OBJECTIVES: This study aimed at assessing the health-related quality of life (HRQoL) and related factors among individuals who had successfully completed treatment for pulmonary tuberculosis (PTB) in Ilorin. 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. HRQoL assessment was conducted in 308 consenting patients who had been certified microbiologically cured for bacteriologically confirmed PTB in the preceding three years using the validated St. George's Respiratory Questionnaire (SGRQ). All subjects also had plain chest radiograph done for assessment of the presence and extent of lung parenchymal damage. RESULTS: The overall total median percentage HRQoL score was 18.5 (7.9-28.2) with the highest score in the activity component [33.7 (18.3-41.8)] and least scores in the impact component [10.0 (0.0-21.9)]. The independent predictors of impaired HRQoL were age > 40 years (p= 0.007), absence of formal education (p=0.004), mMRC score >1 (p= 0.002), PTB retreatment (p=<0.001) and radiographic scores >3 (p= <0.001). CONCLUSION: There is impaired HRQoL following treatment for PTB in Ilorin. Hence, there is a need to incorporate HRQOL assessment as an adjunct outcome measure after PTB treatment especially in those with the above identified risk factors.

Clinicopathological Pattern and Management of Primary Lung Cancer in Ilorin, Nigeria.

BACKGROUND: Lung cancer incidence and mortality rates have increased in some low and medium-resourced countries. OBJECTIVES: This study aimed to describe the clinicopathological pattern and management of lung cancer seen in our setting. METHODS: We reviewed cases of pulmonary neoplasm diagnosed and managed at the University of Ilorin teaching hospital over eight years. Cases with tissue diagnosis were enrolled in the study and relevant clinical data were collected from the medical record using a proforma. DESIGN: Hospital-based retrospective study. RESULTS: Out of the 71 cases of primary lung cancer reviewed, 44(62%) were males and the male to female ratio was 2:1. The mean age was 62±14 years and the occurrence was highest in aged 50-69 years. Thirty (42.3%) with histories of tobacco smoking were males. Adenocarcinoma accounted for 34(54.9%), 23(32.4%) were squamous cell carcinoma, 2(2.8%) were large cell carcinoma and 6(8.5%) were other histological variants. The majority (82.7%) presented at stage III-IV lung cancers, 56.3% had malignant pleural effusion and 74.6% received palliative care. Thirty-eight (53.3%) had chest tube drainage, 19(26.7%) underwent chemical pleurodesis and 22(31.0%) received Cisplatin-based systemic chemotherapy. One patient had curative surgery and none received radiotherapy. At 12 months, 4 (5.6%) were still alive, 14(19.7%) cases had medical records of their death and 53(74.7%) were lost to follow up. CONCLUSION: This study has highlighted the clinicopathological trend, high rate of mortality and late presentation of lung cancer in our setting. There is a need to increase the awareness of the warning signs and risk factors to ensure early detection and facilitate curative therapy.

CONTEXTE: L'incidence du cancer du poumon et les taux de mortalité ont augmenté dans certains pays à faibles et moyennes ressources. OBJECTIFS: Cette étude visait à décrire le modèle clinicopathologique et la prise en charge du cancer du poumon observé dans notre milieu. MÉTHODES: Nous avons passé en revue les cas de néoplasme pulmonaire diagnostiqués et pris en charge à l'hôpital universitaire de l'Université d'Ilorin pendant huit ans. Les cas avec diagnostic tissulaire ont été inclus dans l'étude et les données cliniques pertinentes ont été collectées à partir du dossier médical à l'aide d'un formulaire. CONCEPTION: étude rétrospective en milieu hospitalier. RÉSULTATS: Sur les 71 cas de cancer du poumon primitif examinés, 44 (62%) étaient des hommes et le ratio homme / femme était de 2:1. L'âge moyen était de 62 ± 14 ans et la fréquence était la plus élevée chez les 50 à 69 ans. Trente (42,3%) ayant des antécédents de tabagisme étaient des hommes. L'adénocarcinome représentait 34 (54,9%), 23 (32,4%) étaient des carcinomes épidermoïdes, 2 (2,8%) étaient des carcinomes à grandes cellules et 6 (8,5%) étaient d'autres variantes histologiques. La majorité (82,7%) des cancers du poumon de stade III-IV, 56,3% ont eu un épanchement pleural malin et 74,6% ont reçu des soins palliatifs. Trente-huit (53,3%) ont eu un drainage par sonde thoracique, 19 (26,7%) ont subi une pleurodèse chimique et 22 (31,0%) ont reçu une chimiothérapie systémique à base de cisplatine. Un patient a subi une chirurgie curative et aucun n'a reçu de radiothérapie. À 12 mois, 4 (5,6%) étaient encore en vie, 14 (19,7%) cas avaient un médical de leur décès et 53 (74,7%) étaient perdus de vue. CONCLUSION: Cette étude a mis en évidence la tendance clinicopathologique, le taux élevé de mortalité, et la présentation tardive du cancer du poumon dans notre milieu. Il est nécessaire d'accroître la sensibilisation aux signes avant-coureurs et aux facteurs de risque pour assurer une détection précoce et faciliter la thérapie curative.

Air Quality Index and Respiratory Symptoms among Garri Processing Workers in Ogbomoso, Nigeria.

BACKGROUND: Epidemiological studies have linked morbidity and mortality of individuals to exposure to atmospheric gaseous and particulate matter especially fine particles (PM2.5) and coarse particles (PM10).The process of garri (cassava crisps) production (frying with firewood) is associated with production of gaseous and particulate matter which contribute to ambient particulate matter air pollution. The objective of this study was to determine the impact of air quality indices on the prevalence of respiratory symptoms among the garri processing workers in Ogbomoso. METHODOLOGY: A comparative cross-sectional study was carried out among 351 garri processing workers in Ogbomoso as subjects and 351 residents of Ogbomoso metropolis as controls that were age, sex and height-matched. A semi-structured questionnaire was used to obtain sociodemographic profiles and respiratory symptoms of participants and document physical examination findings. Particulate matter counter was used for air quality sampling. RESULTS: The mean age of subjects was 41.7 ± 14.9 years and that of controls was 41.6 ± 14.7 years (p =0.960). The two groups were also matched for socioeconomic status, sex and height. Prevalence of respiratory symptoms was higher at 48.4% among the garri workers than the control group which was 29.1% (p<0.001). Cough was the predominant symptom with a prevalence of 29.3% and 10.5% among the subjects and controls respectively. The mean count of PM1.0 in garri processing locations was significantly higher than that recorded in Ogbomoso metropolis; 73.77±42.08 vs 15.04±6.66mg/m3 (p<0.0001). CONCLUSION: Garri processing work is associated with significant increase in ambient air pollution and increased prevalence of respiratory symptoms among the workforce compared to the control population. Effective preventive strategies including education and provision of safety masks may reduce the occupational hazards associated with garri processing factory workers in Nigeria.

Acute Oxygen Therapy on Hospital Wards in Low Middle-Income Country: Experience from a Referral Centre in Ilorin, Nigeria.

BACKGROUND: Oxygen is like any other medication that can cause severe consequences if administered inappropriately. OBJECTIVE: To audit the pattern of acute oxygen therapy on regular hospital wards of a referral centre in Ilorin, Nigeria. METHODS: We reviewed 150 patients that received or had a prescription for acute oxygen therapy in three months and extracted relevant information using a proforma. RESULTS: About one-third of the patients (30%) were >65 years of age and the male to female ratio was 1:1. The commonest indication and medical condition for acute oxygen administration were hypoxemia (70.7%) and pneumonia (26.0%), respectively. Pneumonia accounted for most (41.2 %) of the oxygen therapy in childhood. The majority of patients (88.0%) had written order for oxygen prescription, 40.7% had a prescription to target oxygen saturation and only 31.3% achieved their target saturation. Oxygen prescription was adequate (documentation of delivery device, flow rate of oxygen, and target oxygen saturations) in 40.7% of patients. The assessment, monitoring and titration of oxygen therapy were adequate in 92.7%, 65.3% and 28 % of patients respectively. Overall mortality was 27.3% in patients receiving acute oxygen supplementation. Eleven patients had unstable COPD, and 63.6 %, 54.5 % and 45.6 % of them had adequate oxygen prescription, monitoring and titration respectively. The challenges to oxygen use were faulty delivery devices, emptied oxygen cylinders, inability to routinely do arterial blood gas analysis and lack of hospital oxygen protocol. CONCLUSION: The current practice of acute oxygen therapy is not satisfactory and interventions are advocated to improve the healthcare providers' administration of oxygen.

Profile of patients with chronic obstructive pulmonary disease in Ilorin who were never-smokers.

BACKGROUND: The most recognized risk factor for chronic obstructive pulmonary disease (COPD) worldwide is cigarette smoking. However, recent surveys have revealed an increasing trend from nonsmoking causes especially from biomass exposure. This study, therefore, aimed to determine the proportion of patients and the clinical pattern of COPD among never-smokers in Ilorin. SUBJECTS AND METHODS: This is a retrospective study in which case records of patients with clinical diagnosis of COPD from January 2013 to December 2017 were reviewed. Data were collected with respect to their sociodemographic characteristics, clinical details, comorbid illnesses, and severity of the disease. RESULTS: A total of 135 case records of patients with COPD were reviewed, of which 66 had spirometric confirmation of the disease. In all, 38 (57.6%) of them were never-smokers with a male-to-female ratio of 1:1.1. The mean age of the subjects was 64.5 ± 11.7 years. Cough and exertional dyspnea were the most common symptoms (89.5% each), and systemic hypertension was the most common comorbid illness. Firewood exposure constituted the most common nonsmoking risk factor (47.4%), and the majority of the patients had mild COPD. When compared with ever-smokers, the mean post bronchodilator lung function parameters were found to be significantly better in never-smokers. CONCLUSION: Over half of COPD cases in Ilorin were never-smokers with firewood exposure as the main risk factor. This study has further highlighted the need for increased awareness of the hazards of biomass fuel exposure in our setting.

Structural echocardiographic abnormalities seen in HIV/AIDS patients are independent of cd4 count.

INTRODUCTION: The human immunodeficiency virus (HIV) infection remains one of the most daunting public health challenges today. Cardiac involvement in HIV/acquired immune deficiency syndrome (AIDS) is frequent and has been recognized on autopsy since the emergence of the pandemic. The objective of the study was to assess the pattern of structural echocardiographic (echo) findings in HIV/AIDS patients and compare this to the echo findings in apparently healthy HIV-negative controls. MATERIALS AND METHODS: One hundred and fifty HIV-positive patients were recruited consecutively from the HIV patients attending the University of Ilorin Teaching Hospital, Ilorin, North Central, Nigeria. One hundred and fifty age- and sex-matched controls were also recruited from the surrounding community. All the individuals had clinical examination, electrocardiography (ECG) and echocardiography (echo) done. RESULTS: ECG abnormalities were seen in 55.3% of the HIV-positive patients compared with 2.7% of controls (P < 0.001). The overall prevalence of echo abnormalities among the patients was 54%, against 15.3% (P < 0.001) of the controls. All the structural dimensions of the cardiac chambers were significantly greater than the cardiac chamber dimensions in the controls except for left atrial dimension (LAD). When the patients were considered in two groups of those with CD4 count less than 200 cells/mm3 than those with CD4 count more than 200 cells/mm3, the structural chamber dimensions were similar between both groups. CONCLUSIONS: Echo is an important tool for detecting cardiac abnormalities in HIV/AIDS patients. There is a high prevalence of echo abnormalities among HIV patients seen in our centre. The HIV infection was associated with increased structural dimensions of cardiac chambers compared with HIV-negative controls. This however did not seem to be related to disease severity as the chamber dimensions were similar between those with CD4 count below and above 200 cells/mm3.

RISK FACTORS AND SERO-PREVALENCE OF HEPATITIS B SURFACE ANTIGEN AMONG BLOOD DONORS IN UNIVERSITY OF ILORIN TEACHING HOSPITAL, ILORIN, NIGERIA.

BACKGROUND: Availability of safe blood and blood products for transfusion is increasingly difficult globally, especially in developing countries because of high prevalence of Transfusion Transmissible Infections. OBJECTIVES: To determine the prevalence of HBsAg among blood donors and to evaluate the socio-economic, demographic and medical factors associated with its infection. DESIGN: A prospective study. SUBJECTS: Three hundred and fifty consecutive blood donors were recruited. 2 ml of venous blood was collected aseptically from the ante-cubital vein and subjected to serological test for HBsAg. RESULTS: High prevalence rate 10.9% was recorded. All the donors reactive to HBsAg were males (38,100%) with a mean age of 30.7 ± 8.02 years, while 55.3%, 44.7%, 5.3%, 42%, 47.4%, 5.3% of them were single, married, primary school graduate, secondary school graduate, tertiary school graduate and illiterate respectively with 36.8%, 23.7%, 39.5% and 0% been unemployed, civil servants/professionals, skilled artisans and business/petty traders. The most common risk factor was multiple sexual partners 55.3%, followed by extra marital affairs 13.2%, tattooing 10.5%, previous blood transfusion 5.2%, previous surgery 2.6% and sex trading 2.6%. CONCLUSION: Active public enlightenment programmes and strict blood donation selection criteria need to be put in place in order to provide safe blood and blood products for transfusion.

Sero-prevalence of syphilis among patients with mental illness: comparison with blood donors.

BACKGROUND: Mentally ill individuals (MII) are at risk of acquiring syphilis and other sexually transmitted infections. This study aimed at determining sero-prevalence of syphilis among MII and compare them with voluntary blood donors (VBD) at University of Ilorin Teaching Hospital (UITH), Nigeria. METHODS: A cross-sectional study done between June, 2010 and June 2011, and involving 350 each of VBDs and MII in and out-patients of UITH. Serological test was done using venereal disease research laboratory (VDRL) and the Treponema Pallidum Haemagglutination (TPHA) kit. RESULTS: Of the 700 subjects, 324 (92.6%) MII, and 349 (99.7%) VBDs were <55 years; 71 (21.4%) MII were Civil Servants compared with 96 (27.4%) VBDs. Significantly more VBDs had higher education than MII (185 or 52.9%, and 140 or 40% respectively). Christians constituted the majority (176 or 50.3%) among MII, and Muslims (210 or 60%) among VBDs. Significantly more married VBDs (204/206 or 99.0%) live with spouses; more VBDs consumed alcohol (37 or 10.6%), smoked (19 or 5.4%), and engaged in extramarital sex (105 or 30.0%). Significantly more MII had blood transfusion (40 or 11.4); engaged in sex trade (12 or 3.4%); and more syphilis prevalence (5.4%). In addition, more syphilitic MII smoked (18 or 94.7%); and all syphilitic MII had psychotic disorders. CONCLUSION: The prevalence of syphilis in MII is significantly higher than among VBDs. Routine screening of MII is advocated to stem this problem.

Factors affecting interest in respiratory medicine as a subspecialty of choice: survey of internal medicine residents in Nigeria.

AIMS AND OBJECTIVES: The objective of this study was to determine the factors that affect the interest in respiratory medicine (RM) as a subspecialty of choice among internal medicine residents in Nigeria. SUBJECTS, MATERIALS AND METHODS: This was a cross-sectional study of 136 internal medicine residents recruited from seven teaching hospitals from January 2011 to June 2011. A semi-structured questionnaire that was self administered by residents was used to obtain socio-demographic information and factors affecting residents' interest in respiratory medicine. RESULTS: Out of 136 residents that completed the study, 78 (57.4 %) were junior residents (PG year 1-3) and 58(42.6%) were senior residents (PG year >3). Thirty four (43.6%) junior residents and 21(36.2%) senior residents considered respiratory medicine as a sub-specialty of choice. Only 2(3.5%) of the senior residents were presently committed to RM. In the junior residents, interest in respiratory medicine was correlated with personal intelligence and ability (RR=2.58, ;95% confidence interval(CI): 1.16-7.07, p-0.01) , availability of respiratory physician (RR=2.42; 95% CI 1.07-7.63 ,p-0.02) and postgraduate examiners in RM in training institutions RR= (2.20; 95% CI 1.06-5.45,p-0.03), experience during rotation in medical school and residency (RR=2.11 ; 95% CI 1.11-4.21,p-0.03) and future annual income (RR=2.04;C:I1.03-4.68,p-0.04). In the senior residents, interest in RM was correlated with the availability of postgraduate examiners in RM in training institutions (RR- 6.36; 95% CI 1.16-66.80, P-<0.01), future opportunity for scholarships and travel grants (RR- 4.23; 95% CI 1.19-25.92,p-< 0.01), personal intelligence and ability (RR= 3.41; 95% CI.16-13.87,p-0.01) and prospect for rapid elevation in career (RR=2.92; 95% CI 1.03-11.91,p -0.04). Provisions of modern facilities in training institutions, mentoring by senior colleagues and promotion of subspecialty by respiratory physicians were rated by the senior residents as the most important ways of increasing interest in respiratory medicine and making it a specialty of choice. CONCLUSION: The interest in respiratory medicine among internal medicine residents is low and decline as their level of training advances. The factors affecting the interest in respiratory medicine have been highlighted and the policy makers need to understand, and if possible modify these factors by formulating appropriate changes to our training programs so as to increase future numbers of respiratory physician.

Prevalence of cough among adults in an urban community in Nigeria.

BACKGROUND: Cough is the commonest symptom for which patients seek medical attention and may be a warning sign of an impending disease. OBJECTIVE: To determine the prevalence of cough among adults in an urban community in Nigeria. METHODS: We conducted a cross sectional study among subjects aged >18 years from May 2009 to October 2009 in Ilorin, Nigeria. A semi-structured questionnaire was used to collect the data. The American College of Chest Physicians (ACCP) and the European Respiratory Society (ERS) cough guidelines were used to define acute, sub acute and chronic cough. RESULTS: A total of 472 subjects participated in this study, 238(50.4%) were men and 234(49.6%) were women. Ninety-seven (20.6%) had cough in the preceeding 12 months. Thirty-one (6.6%) had cough at the time of interview, of which 17(3.6%) were productive. The prevalence of acute cough was 3.8%, sub acute 1.7% and chronic cough was 1.1%. All types of cough were common in those aged <45 years, unskilled workers, low educational attainment, while chronic cough was common in the women. The risk of coughing increased with tobacco smoking and the number of sticks smoked per day. Majority of subjects with acute cough [16(88.9%)], sub acute cough [8(100%)] and chronic cough [3(60 %)], were yet to consult a doctor. CONCLUSION: Our study revealed a low prevalence of cough among adults in this urban community in Nigeria. It is imperative to enlighten the community on the importance of seeking early treatment for cough, which may be a warning sign of life threatening lung disease.

Status disclosure among People Living with HIV/AIDS in Ilorin, Nigeria.

BACKGROUND: HIV/AIDS is a disease that is characterised by discrimination and stigmatisation particularly in Africa. OBJECTIVE: To determine rate of disclosure of HIV status among People Living with HIV/AIDS (PLWHA) in Ilorin, Nigeria. METHODS: A semi-structured, interviewer administered questionnaire containing 40 items was used to collect information from persons living with HIV/AIDS accessing treatment at the University of Ilorin Teaching Hospital, Ilorin, Nigeria. Information on patients' socio-demography and life-style history, HIV medical history and HIV status disclosure was obtained from the patients. RESULTS: A total of 253 patients participated in the study. Their ages ranged between 26 and 58 years. Majority were females, 58.5% and 41.5% were males. The disclosure rate was 39.5%. As many as 60.5% of the respondents had not disclosed their HIV status to anybody. The disclosure was to the spouses, in 18.6% of the instances and to relatives or friends or co workers in another 20.6% of cases. There was a significant difference. The knowledge of their spouses on HIV/AIDS status correlated with disclosure rate, r=0.237, p=0.02. Female sex, intact family and monogamy correlated well with high disclosure rate. CONCLUSION: HIV status disclosure rate among PLWHA in Ilorin is low. Female sex and monogamous marital status are positive predictors of disclosure. There is need to ensure effective disclosure counselling for the unmarried; single/ separated, patients in polygamous marriages and males member of the society.

Profile and outcome of unilateral tuberculous lung destruction in Ilorin, Nigeria.

BACKGROUND: Unilateral tuberculous lung destruction is a serious chronically disabling and often fatal complication of pulmonary tuberculosis. A few previous studies have dealt with some aspects of this entity among Nigerians with pulmonary tuberculosis but these studies may not truly reflect its current trends. OBJECTIVE: To describe the presenting profiles and outcome of unilateral tuberculous lung destruction among patients with pulmonary tuberculosis. METHODS: The study was a chart review of the medical records of adult patients with pulmonary tuberculosis complicated by unilateral lung destruction seen between January 1999- December 2008. Data extracted included demographic, and outcome of treatment. The clinical features, sputum results and illustrative cases are presented. RESULTS: Unilateral lung destruction complicated 74(1.3%) of 5,926 pulmonary tuberculosis cases seen over the review period. Most cases occurred in males [45(60.8%)] and they were predominantly [51(68.9%)] below 40 years of age. Most of them [52(70.2%)] presented after six months of symptoms. Forty-seven (63.5%) of them had had previous exposure to antituberculosis drugs. The left lung was affected in 49 (66.2%) patients. Only 25 (33.8%) of them were cured while the adjusted mortality rate was 25.5%. Male gender, presence of dyspnoea on mild exertion and right ventricular failure were significantly associated with increased mortality. CONCLUSION: Unilateral tuberculous lung destruction has unacceptably high mortality rate which can be prevented by patient presenting early to the hospital, prompt diagnosis and strict adherence to the standard treatment.

Methicillin resistant Staphylococcus aureus: awareness, knowledge and disposition to screening among healthcare workers in critical care units of a Nigerian hospital.

BACKGROUND: Awareness level about methicillin resistant Staphylococcus aureus (MRSA) is high in the western world but the status in developing countries is not well defined. OBJECTIVE: To assess MRSA awareness level, knowledge and disposition to screening among critical healthcare givers (HCGs) in Nigeria. METHODS: A self-administered questionnaire was used to assess the level of awareness and knowledge of HCGs in critical care units of the University of Ilorin Teaching Hospital, Ilorin, Nigeria on MRSA and their willingness to submit to screening. RESULTS: Only 103 (52.0%) of the 198 participants were aware of MRSA but all were favourably disposed to screening for the organism. Awareness was through hospital rounds 65(63.1%) and journals/ textbooks 35(34.0%), and Many, 120 (60.6%) considered MRSA as a threat in the hospital, while only 27 (13.6%) thought otherwise and 51(25.8%) were indifferent. Most HCGs, 124 (87.9%) reported that there were no MRSA control measures in their respective duty post. The age, cadre of work, and number of years in the hospital's critical care units correlated positively with awareness level. CONCLUSION: Methicillin resistant Staphylococcus aureus awareness level among the HCGs in our hospital is just a little above 50.0% with substantial proportion of them not realizing the medical implication of the organism. However, majority are well disposed to MRSA screening. Inadequate publicity is a major contributor to poor knowledge and awareness. There is need for educational intervention and sensitization programs on MRSA and other infection control techniques for HCGs in developing nations especially Nigeria.

Utilisation of spirometry among hospitalised patients with clinical findings of COPD in a tertiary hospital in Nigeria.

AIMS AND OBJECTIVE: The aim of this study was to determine the rate of spirometry utilisation among hospitalised patients with clinical findings of chronic obstructive pulmonary disease (COPD) in a tertiary hospital in Nigeria. PATIENTS AND METHODS: A case record review of hospitalised patients with clinical findings of COPD from January 2002 to June 2009 from the record of the cardiopulmonary unit of the University of Ilorin Teaching Hospital Ilorin, Nigeria was carried out. Age and sex, hospital stay, admitting physician, and outcome of admission were obtained. RESULTS: A total of 228 patients were hospitalised with clinical findings of COPD, 185 (81. 1%) were males and 43(18.9 %) were females. The rate of utilisation of spirometry in hospitalised patients (228) with clinical findings of COPD was 8.3%. More than half of those that had spirometry were aged ≥ 65 years. Majority (16; 84.2%) of those that underwent spirometry were under the care of the pulmonologist (p

Sickle cell chronic lung disease among young adult Nigerians.

BACKGROUND: Sickle cell chronic lung disease (SCLD) is often underappreciated by health care providers because its exact prevalence and methods of diagnosis have not been well studied. OBJECTIVE: To describe the pattern of SCLD among young adult Nigerians with sickle cell anaemia (SCA).its exact prevalence and methods of diagnosis have not been well studied. OBJECTIVE: To describe the pattern of SCLD among young adult Nigerians with sickle cell anaemia (SCA). METHODS: Ninety (43 males and 47 females) patients with SCA who were selected by balloting and 90 (54 males and 36 females) healthy subjects with normal adult haemoglobin were studied. Their ventilatory function test (spirometry and peak expiratory flow rates), radiological and electocardiographic parameters were obtained and analyzed for SCLD. RESULTS: Seventeen (18.9%) of the patients had SCLD. Majority (94.1%) of them were in stage1 disease, 5.9% in stage two, and none in the more advanced stages3 and 4. The number of patients with SCLD increased with increasing age. SCLD was associated with more than five previous hospital admissions: 82.4%, (OR of 10.02; CI:4.51 to 22.22) and presence of symptoms suggesting previous acute chest syndrome: dyspnoea in 58.8% (OR of 33.33, CI 7.39 to 150.30); chest pain in 94.1%, (OR of 81.33, CI 9.83 to 672.85); and cough in 47.1%, (OR of 64.00, CI 7.15 to 572.60). CONCLUSION: SCLD may not be a rare event in Nigeria. Therefore efforts should be made to diagnose it in the early asymptomatic stage so as to offer effective intervention therapy to halt progression to the more disabling advanced stages.

Influence of performance status on the risk and outcome of nosocomial pneumonia in the elderly admitted to an open medical ward.

BACKGROUND: nosocomial pneumonia (NP) has been observed to complicate the course of management of some elderly patients in medical wards and this impacts negatively on the outcome of care of this group of patients. OBJECTIVE: to determine the relationship of pre-treatment performance status (PTPS) on the risk and outcome of NP in elderly patients admitted to an open medical ward. METHODS: a prospective clinical surveillance of all elderly patients admitted to the medical wards of a University Teaching Hospital was carried out over a period of nine years. RESULTS: in the nine-year period 531 patients; aged 65 to 107 years were seen, 184(34.7%) of whom developed NP. Eleven (21%) patients had PTPS of 75% or more (i.e. able to care for selves without assistance), one (0.2%) of whom developed NP. Seventy-eight (14.7%) patients had PTPS of 51-74% (i.e. required occasional assistance for routine care); 13(2.4%) of whom also developed NP. Of the 217 (40.9%) patients who had PTPS of 26-50% (i.e. requiring considerable assistance for self care), 73(13.7%) of them had NP while 97 (18.3%) out of 225 patients with PTPS below 25% (i.e. completely dependent on others for routine care) developed nosocomial pneumonia. CONCLUSION: a low performance status score increases the risk of development of NP in the elderly and this risk is influenced by type of treatment-related interventions a patient has on admission.

Prevalence of self reported allergic rhinitis and its relationship with asthma among adult Nigerians.

OBJECTIVES: The aims of the study were to establish the prevalence of self-reported allergic rhinitis in an adult Nigerian population and to examine the relationship between asthma and allergic rhinitis. METHODS: We conducted an epidemiological study of adults aged between 18 and 45 years in Ilorin, Nigeria from 2005 to 2006. An adaptation of the European Community Respiratory Health Survey questionnaire was administered by trained assistants to obtain information on demographics, history of nasal allergies, asthma symptoms, and smoking history. The participants also underwent spirometry. RESULTS: Of the 761 individuals screened, 733 were recruited, giving a participation rate of 96.3%; 441 (60.2%) were men and 292 (39.8%) were women. The prevalence of allergic rhinitis and asthma was 29.6% (n = 217) and 14.7% (n = 108), respectively. Of the individuals with allergic rhinitis, 31.8% (n = 69) had asthma and of those with asthma, 63.9% (n = 69) had allergic rhinitis. The mean (SD) age of those with allergic rhinitis was 31 (7.5) years and 65% (n = 141) were men. The determinants of asthma in individuals with allergic rhinitis were a family history of asthma (odds ratio [OR], 3.38), a history of smoking (OR, -2.58), high socioeconomic status (OR, 3.82) obesity (OR, 3.32), and wheezing (OR, 250). Lung volumes were reduced in those with both asthma and allergic rhinitis compared to those with allergic rhinitis alone. CONCLUSION: Our study revealed a high prevalence of allergic rhinitis in individuals with asthma. It is therefore important to increase awareness of the existence of allergic rhinitis and asthma as a common airway disease to ensure adequate management and control of both conditions.

Serum lipids and glucose abnormalities in HIV/AIDS patients on antiretroviral therapies.

BACKGROUND: With the introduction of highly active antiretroviral therapy (HAART) the outlook of HIV/AIDS has changed from a killer disease to a treatable chronic infectious one. However HAART is associated with some metabolic disorders some of which are now being seen in people living with HIV/ AIDS (PLWHA) accessing care from our centre. OBJECTIVE: To determine the prevalence and pattern of dyslipidaemia and dysglycaemia amongst Nigerian HIV/AIDS patients on HAART. METHODS: PLWHA who were regular on ART for at least three months and had pre-treatment CD4+ count, fasting lipid and glucose profiles were grouped into two treatment regimens: protease inhibitor, (PI) or non-nucleoside reverse transcriptase inhibitor (NNRTI). Pre and post-exposure metabolic and non-metabolic variables were compared for each regimen as well as within regimen comparison of the differences between post exposure metabolic variables. RESULTS: Three hundred and twenty-seven patients; [male = 134 (41%), female = 193 (59%)] met the study criteria in the two groups: PI = 94 (29%) and NNRTI = 233 (71%). The pretreatment metabolic changes in both groups (PI vs. NNRTI) were low HDL-C; 29 (31%) vs. 77 (33%), followed by hypertriglyceridaemia; 16 (17%) vs. 38 (16%) and hypercholesterolaemia; 6 (6%) vs. 10 (4%). After exposure to two different HAART regimens hypertriglyceridaemia and hypercholesterolaemia became more prevalent especially with Pi based therapy than NNRTI; 74 (79%) vs. 108 (54%) and 58 (51%) vs.72 (31%) respectively. These relative higher risks of a PI containing regimen to induce hypertriglyceridaemia and hypercholesterolaemia were about three times more than that of NNRTI, both risks were statistically significant; p = 0.0003 and p = 0.0001. CONCLUSION: Low HDL-C, hypertriglyceridaemia and hypercholesterolaemia are common in untreated HIV/AIDS patients. HAART especially those including protease inhibitors worsens this dyslipidaemia.

Early experience with outpatient tube drainage for management of pleural collections.

BACKGROUND: Increasing cases of pleural effusion leads to pressure on bed spaces and a stretch of the limited facilities available for intervention in our centre. This therefore prompted a search for acceptable alternative way of treatment. OBJECTIVE: To evaluate the use of ambulatory drainage system for chronic infectious and malignant pleural effusion on outpatient basis. METHODS: Eight of 113 routinely performed closed tube thoracostomies drainage were converted to ambulatory drainage system at the time of patients discharge to follow-up clinic. This was after the catheter care had been thoroughly explained to the patients and their relatives. RESULTS: Eight patients (seven males and one female) had ambulatory outpatient tube management. Their mean age was 44.9 (18) years with a range of 22 to 70 years. Histologically confirmed causes of the effusion were; metastatic adenocarcinoma in two(25%) of the cases; chronic nonspecific inflammation in another two(25%) and tuberculous empyema thoracis in three(37.5%) one of whom had TB and HIV coinfection and one(12.5%) of chronic bacterial parapneumonic empyema. One case each of metastatic adenocarcinoma and chronic non-specific suppuration had failed chemical pleurodesis before the outpatient drainage procedure. Half of the cases (including tuberculous and non-tuberculous) were successfully weaned off their catheters. Minor complications such as pain, discomfort, minimal stoma bleeding, and peri-catheter leak were recorded. Rapid fluid re-accumulation prevented weaning in two (25%) of the cases. CONCLUSION: Out-patient chest tube drainage is effective for the management of both malignant and suppurative pleural effusion. This approach would reduce the ever increasing cost of hospital care for this group of patients.
