RESUMEN
Childhood interstitial lung disease (ChILD) diagnosis often requires surgical lung biopsy after the common causes are ruled out. However, surgical lung biopsy has its own set of complications. Hence transbronchial lung cryobiopsy has been used in various studies of adult interstitial lung disease (ILD) with good yield and minimal complications. But this newer mode is rarely used in diagnosing children with suspected ILD. Here, we present the first case of the use of this technique in an infant via a rigid tracheoscope.
RESUMEN
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.

INTRODUCTION: Large vessels are often encountered during endobronchial ultrasound (EBUS). Safety of traversing the vessels weighed against a more invasive procedure can be a dilemma. MATERIAL AND METHODS: We describe a case series of 8 patients who underwent transvascular needle aspiration during EBUS, to access a lesion in the absence of an alternate safe window. A 21 gauge EBUS needle was used to traverse either the main or a major branch of the pulmonary artery. RESULTS: Malignancy was suspected at ROSE in five cases. Granuloma and necrosis noted in 2 cases were confirmed as tubercu-losis on culture. Diagnostic yield of EBUS-TVNA was 87.5% (7/8). No complications were noted in the immediate post-operative period as well as during 6 months of follow up. CONCLUSION: EBUS-TVNA in carefully selected patients is a feasible alternative to more invasive procedures with excellent yield. Appropriate intraoperative, perioperative and postoperative monitoring and care must be available in the case of fatal bleeds.
