Pulmonary alveolar microlithiasis (PAM) is a rare disease characterized by widespread localization of calcispherites in the alveolar spaces. The patients are symptomless for a long time. Nevertheless, this disease slowly develops into pulmonary fibrosis and cardiac failure. The chest X-rays and high-resolution computed tomography strongly point towards a diagnosis of PAM. As for therapeutic approaches, repeated broncho-alveolar lavages (BAL) have been performed with improvement of symptoms but without recovery, and a new oral drug treatment is still under way. We report 2 familial cases of PAM. Both patients underwent chest X-ray examination showing diffuse bilateral micronodular opacities of calcific density. After 5 years, in May 1993, one of them developed exertional dyspnoea, cyanosis, dry cough and was admitted to our Division. Cardiokinetic and diuretic drugs as well as oxygen were administered with satisfactory results. Then repeated BAL were performed. The chest X-ray after 6 months of sodium etidronate (300 mg t.i.d.) administration was unchanged.

Purpose: Identifying therapeutic targets for Signet Ring Cell Carcinoma (SRCC) of the colon and rectum is a clinical challenge due to the lack of Patient-Derived Organoids (PDO) or Xenografts (PDX). We present a robust method to establish PDO and PDX models to answer address this unmet need. We demonstrate that these models identify novel therapeutic strategies targeting therapy resistance and peritoneal metastasis.

Introduction: Diesel exhaust particles (DEP) have been proven to aggravate asthma pathogenesis. We previously demonstrated that concurrent exposure to house dust mite (HDM) and DEP in mice increases both eosinophils and neutrophils in bronchoalveolar lavage fluid (BALF) and also results in higher levels of neutrophil-recruiting chemokines and neutrophil extracellular trap (NET) formation compared to sole HDM, sole DEP or saline exposure. We aimed to evaluate whether treatment with anti-IL-5 can alleviate the asthmatic features in this mixed granulocytic asthma model.

Background: Advanced respiratory monitoring through the measurement of esophageal pressure (Pes) as a surrogate of pleural pressure helps guiding mechanical ventilation in ICU patients. Pes measurement with an esophageal balloon catheter, the current clinical reference standard, needs complex calibrations and a multitude of factors influence its reliability. Solid-state pressure sensors might be able to overcome these limitations.

Lower respiratory tract infections are particularly frequent in hematological patients; their early diagnosis and the timely start of targeted therapy are essential. Bronchoalveolar lavage (BAL) can provide a microbiological sample from the lower airways in a minimally invasive way. This study aimed to determine the diagnostic yield of BAL in hematological patients for microbiological purposes and its influence on modifying the therapeutic strategy.
