A study on the prevalence of RLS in OSA and the consequences of co-occurrence.

Background: Restless leg syndrome (RLS) is common among patients with obstructive sleep apnoea (OSA) but the prognostic importance of this is not studied. We have called OSA and RLS coexistence as ComOSAR.

Materials And Methods: A prospective observational study was done on patients referred for polysomnography (PSG) with the aims to evaluate 1) the prevalence of RLS in OSA and comparing it with RLS in non-OSA, 2) the prevalence of insomnia, psychiatric, metabolic and cognitive disorders in ComOSAR versus OSA alone, 3) chronic obstructive airway disease (COAD) in ComOSAR versus OSA alone.

Prevalence, risk factors and effects of restless legs syndrome in COPD patients.

Restless legs syndrome (RLS), a sensory motor disorder, is commonly seen amongst chronic obstructive pulmonary disease (COPD) patients. We conducted a study to know its prevalence in COPD and analyse the possible cause and effect of RLS. It is an analytical cross-sectional study conducted between July 2016-December 2020.

A follow-up study of post infectious obliterative bronchiolitis in adults and comparative analysis with chronic obstructive pulmonary disease.

Objectives: The objective is (1) To evaluate the change in forced expiratory volume in one second (FEV), forced vital capacity (FVC), dyspnea grading, body mass index, and oxygen saturation (SpO) in adults with postinfectious obliterative bronchiolitis (PIOB) over a period of time (2) To evaluate the same parameters in chronic obstructive pulmonary disease (COPD) patients and compare with PIOB.

Materials And Methods: It was a retrospective observational study involving appropriately managed patients of PIOB and COPD with minimum 3 years of follow-up. Out of a total of 106 patients who followed up from January 2019 to December 2019 and had a follow-up data of more than 3 years, 61 (31 COPD and 30 PIOB) patients were included in the final analysis after applying the inclusion and exclusion criteria.

COPD sleep phenotypes: Genesis of respiratory failure in COPD.

The chronic obstructive pulmonary disease (COPD) patients could have respiratory failure during sleep without daytime overt arterial blood gas (ABG) abnormality. We undertook a study first of its kind to attempt in distinguishing the underlying pathophysiological mechanisms.  It was a prospective observational study in stable COPD patients.

A young lady with dyspnoea: Quest for the cause.

Pulmonary hypertension (PH) is a common cause of dyspnoea. The management and prognosis of PH varies with the underlying aetiology. Hence the detection of the cause of PH is important.

Prevalence of sleep disorders in chronic obstructive pulmonary disease and utility of global sleep assessment questionnaire: An observational case-control study.

Introduction: Although sleep disorders in chronic obstructive pulmonary disease (COPD) are common, no study has comprehensively evaluated sleep disorders in COPD, and there are no screening tools available for COPD patients. Global sleep assessment questionnaire (GSAQ) is one of the best screening tools for the general population.

Aims And Objectives: The aims and objectives of the study were to find (i) the prevalence of sleep disorders in COPD based on GSAQ score; (ii) if the GSAQ score in COPD is high compared to healthy adult population; (iii) the prevalence of insomnia, obstructive sleep apnea (OSA), restless leg syndrome (RLS), and depression in COPD patients; and (iv) the sensitivity and specificity of GSAQ.

Blowing Balloons and Pulmonary Talcosis: An Uncommon Hazard.

A 65-year-old nonsmoker man presented with bilateral upper lobe conglomerated calcific opacities with basal reticulations. The patient denied any significant occupational exposure. Repeated and persistent enquiry revealed an intense exposure to talc 20 years back, from blowing balloons stained with talc powder for a period of 1 year.

A "triple whammy" in adenocarcinoma lung.

Osimertinib (AZD9291), a third-generation epidermal growth factor receptor (EGFR)-tyrosine-kinase inhibitor (TKI), is useful in the treatment of non-small cell lung cancer who show resistance to first-generation EGFR-TKIs and harbor T790M mutation. Acquisition of resistance to osimertinib due to several mechanisms has been reported. We report the first case of an Indian patient with osimertinib resistance, due to C797S mutation.
