Effect of noninvasive respiratory support on interstitial lung disease with acute respiratory failure: A systematic review and meta-analysis.

Background: Primary studies have demonstrated the effectiveness of noninvasive respiratory supports, including noninvasive positive pressure ventilation (NIPPV) and high flow nasal cannula (HFNC), for improving oxygenation and ventilation in patients with interstitial lung diseases (ILDs) and acute respiratory failure (ARF). These studies have not been synthesized and are not included in current practice guidelines. This systematic review with meta-analysis synthesizes studies that compared the effectiveness of NIPPV, HFNC and conventional oxygen therapy (COT) for improving oxygenation and ventilation in ILD patients with ARF.

Discovery and validation of circulating miRNAs for the clinical prognosis of severe dengue.

Background: Early prognostic markers of severe dengue may improve case management and reduce dengue-related mortalities. This study aimed to identify circulating microRNAs (miRNAs) as biomarkers for predicting severe dengue.

Methodology: Serum samples from dengue-infected patients were collected on the first day of admission.

Diffuse endobronchial metastasis from sigmoid carcinoma presenting as wheezing and respiratory failure.

A 66-year-old Thai man with underlying asthma, history of traumatic right haemothorax, and sigmoid carcinoma with bladder invasion developed productive cough, whitish sputum, dyspnoea, and wheezing for 2 months. Physical examination showed generalized expiratory wheezing in both lungs. Computed tomography scan of the chest revealed diffuse thickening of bronchial wall, predominantly at lower lobes; several various sizes of pulmonary nodules; diffuse interlobular septal thickening; multiple enlarged mediastinal lymph nodes and hilar lymph nodes; and right pleural effusion.
