ABSTRACT
OBJECTIVES@#The aim of this study was to evaluate pulmonary function in patients with mandibular fractures and to determine the pattern of pulmonary functions in these patients.@*MATERIALS AND METHODS@#This was a cross-sectional study of pulmonary functions in Nigerian non-smoking patients with isolated mandibular fractures managed at our health institution from December 2015 to June 2017. Forced vital capacity (FVC), forced expiratory volume in one second (FEVâ‚), peak expiratory flow rate (PEFR), and ratio of FEVâ‚ to FVC (FEVâ‚/FVC) were measured for all participants using a portable spirometer just before treatment. The pulmonary indices were compared with the predicted reference values for Nigerians to determine the respiratory pattern.@*RESULTS@#Forty participants consisting of six females (15.0%) and thirty-four males (85.0%) with a female to male ratio of 1:5.7 were included in this study. The mean patient age was 34.5±13.1 years (range, 17–63 years). The mean FVC, FEVâ‚, FEVâ‚/FVC, and PEFR were 3.8±1.2 L, 3.0±1.0 L, 74.3%±13.8%, and 5.2±2.2 L/s, respectively. Comparison of data with predicted values revealed that 17 subjects (42.5%) had normal pulmonary function pattern while 23 subjects (57.5%) had features suggestive of obstructive and restrictive pulmonary function patterns.@*CONCLUSION@#Isolated mandibular fractures presented with abnormal pulmonary function pattern.
ABSTRACT
OBJECTIVES: The aim of this study was to evaluate pulmonary function in patients with mandibular fractures and to determine the pattern of pulmonary functions in these patients.MATERIALS AND METHODS: This was a cross-sectional study of pulmonary functions in Nigerian non-smoking patients with isolated mandibular fractures managed at our health institution from December 2015 to June 2017. Forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), peak expiratory flow rate (PEFR), and ratio of FEV₁ to FVC (FEV₁/FVC) were measured for all participants using a portable spirometer just before treatment. The pulmonary indices were compared with the predicted reference values for Nigerians to determine the respiratory pattern.RESULTS: Forty participants consisting of six females (15.0%) and thirty-four males (85.0%) with a female to male ratio of 1:5.7 were included in this study. The mean patient age was 34.5±13.1 years (range, 17–63 years). The mean FVC, FEV₁, FEV₁/FVC, and PEFR were 3.8±1.2 L, 3.0±1.0 L, 74.3%±13.8%, and 5.2±2.2 L/s, respectively.

ABSTRACT
Background:Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disorder commonly assessed by spirometryand health related quality of life (HRQoL) questionnaires. COPD assessment test (CAT) is a new questionnaire used for HRQoL evaluation especially in a clinic setting. Aims:To assess HRQoL using the CAT, and to determine the relationship of CAT to other measures of COPD such as pulmonary function test (PFT), dyspnea and six minutes walking distance test (6MDWT) among patients with COPD in Nigeria.Settings and Design:Cross-sectional study.Methods:Sixty stable patients with a clinical and spirometric diagnosis of COPD according to the GOLD criteria were recruited into the study. Spirometry was performed according to ATS/ERS guidelines. Health status, dyspnea and functional capacity of the patients were assessed using the CAT questionnaire, modified medical research council (MMRC) dyspnea scaleand six-minute walking distance (6MDWT) respectively.Results:The mean age was 68.8 years ± 10.3. Sixty percent of the study participants were male. The mean BMI was 21.6 ± 4.8 kg/m2, 37(61.7%) of the patients were ex-smokers, 3.3% were current smokers and 35% were never smokers. In terms of frequency of exacerbations 18.3% had ≤ 1 per year and 5.0% had ≥ 2 per year. The CAT was strongly associated with 6MWDT (r = 0.85P < 0.001), FEV1% predicted (r= 0.67, P< 0.001) and with MMRC (r=0.64, p<0.01).Conclusions:CAT scores correlated well with percent FEV1, dyspnea and exercise tolerance which measures various aspect of COPD. It may serve as an easy to administer sensitive tool in assessing stable COPD in outpatientclinics especially in low resource countries
