ABSTRACT

Background: The coexistence of obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD) is termed "Overlap syndrome (OS)." Objectives: The present study aimed at estimating the prevalence of OS among patients diagnosed with OSA. Methods: It was a prospective observational study conducted on patients presenting to respiratory medicine outpatient department (sleep clinic) with symptoms of sleep-disordered breathing and was found to have OSA by overnight polysomnography. These patients were then subjected to spirometry to diagnose COPD. Results: The prevalence of OS in the study population was found to be 41.3%. Excessive daytime sleepiness was found to be higher in overlap group patients (P = 0.033), the difference was statistically significant. The mean age (59.9 ± 9.6 years) was found to be high in the OS group compared to those without the same. The mean forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and FEV1/FVC (pre- and postbronchodilator) spirometry parameters were found to be lower in patients with OS. Conclusion: The study showed that the prevalence of OS in the present study was 41.3%. Excessive daytime sleepiness and age >60 years were risk factors for OS in a patient with OSA. OS patients had lower pulmonary function values.

ABSTRACT

Background: The change in FEV1 after administration of a short-acting bronchodilator has been widely used for diagnosis of obstructive airway diseases. Many factors can influence the post bronchodilator reversibility. Aim: The aim of the present study was to estimate the presence of reversibility among the patients of obstructive airway disease and to identify the factors affecting it. Methods: Patients who presented to the department of respiratory medicine with symptoms of dyspnea were evaluated with spirometry. Spirometry and post bronchodilator reversibility (BDR) was defined as per international guidelines. SPSS 17 was used for statistical analysis and P < 0.05 was considered significant. Results: Out of 100 patients studied, 33 had BDR. Median age of the population was 58 ± 17 years. There were 72 non-smokers and 58 men. A total of 32 had chronic obstructive pulmonary disease (COPD), 56 had asthma, and 12 had normal spirometry. The median pre and post bronchodilator FEV1 was 1.34L/Sec and 1.46 L/sec respectively. Twenty-seven of asthma (41%) and 6 of COPD (19%) had BDR (P = 0.05). Other factors associated with BDR were smoking (P = 0.035). There was no statistically significant correlation found between eosinophilia, gender, severity of obstruction, BMI, height, weight and age. Conclusion: The prevalence of post BDR in the study population was 33%. The factors affecting BDR were smoking status, and asthma. The study did not show any significant correlation between BDR and eosinophilia, gender, height and age.

ABSTRACT

Sarcoidosis is a multi-system granulomatous disorder characterized by involvement of multiple systems with or without lymphadenitis. Pulmonary complications are common and may lead to morbidity. Breast cancer is one of the commonest malignancy among women across the world. There is an increased risk of malignancies in sarcoidosis. This association with cancer creates a diagnostic dilemma due to the predominant involvement of nodes and organ systems in both conditions. Here we report three cases of sarcoidosis with breast cancer diagnosed over one year.
