M.M. Akpan, A.A. Adegoke

 

Abstract

Introduction: Nontuberculous recurrent cough is becoming rampant among hospitalized patients.

Aim: Hospitalized patients and out-patients in some hospitals in Cross River State were studied for the prevalence of nontuberculous recurrent cough in the state

Methods: This was carried out using standard procedures in Microbiology.

Results: The bacterial isolates from the sputum samples were Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae, Escherichia coli, Klebsiella pneumoniae, and Corynebacterium diphtheriae. The patients’ age group 20 – 39 years had the highest prevalence of non – tuberculous recurrent cough (46.7%) while the least prevalence of 1.0% was among the age group ≥ 80 years. The prevalence rate of 33.7% was the highest among the social class and businessmen, while the least prevalence rate of 8.2% was found among students. Out of a total of 1466 samples studied, 93.6% was nontuberculous cases.

Conclusion: Mycobacterium tuberculosis is therefore not the predominant cause of cough in the study area as at the time of this study

Studies On The Distribution Of Clinically Diagnosed Pulmonary Tuberculosis In Ebonyi State, Nigeria

RK Obi, AN Amadi, IM Idika, FC Nwanebu

 

Abstract

A study was conducted between January, 2005 to December, 2006 to ascertain the prevalence of pulmonary tuberculosis among patients who attended chest clinics in some randomly selected hospitals, Clinics and Health Centers in Ebonyi State, Nigeria. Investigations were carried out using the two popular diagnostic criteria for pulmonary tuberculosis namely the specific Ziehl Neelsen (ZN) methods and chest X-ray. A total of 962 patients with clinical signs and symptoms of tuberculosis were studied. Out of this figure, 559 (58.1%) had pulmonary tuberculosis with 1:1 male/female ratio. There was no significant difference between ZN sputum smear positive and chest x-ray in the diagnosis of pulmonary tuberculosis in the studied population at 95% confidence level. The possible reasons for the high prevalence of pulmonary tuberculosis may be attributed to increase in the incidence of HIV/AIDS, high rate of poverty, emergence of drug-resistant strains of Mycobacteria and to a lesser extent, smoking and diabetes
