Alveolar Microlithiasis with Mild Clinical Symptoms But Severe Imaging Findings: A Case Report.

Pulmonary alveolar microlithiasis (PAM) is a rare genetic disorder that causes calcium phosphate microliths to form in the alveoli. Symptoms usually appear in a person's third or fourth decade of life. A definitive diagnosis does not always demand a lung biopsy but can be achieved in families with more than one member with PAM and compatible chest imaging.

Chest computed tomography severity score is a reliable predictor of mortality in patients with chronic obstructive pulmonary disease co-infected with COVID-19.

Background: Coronavirus disease 2019 (COVID-19) pandemic is considered a global health crisis. The data related to chronic obstructive pulmonary disease (COPD) patients with COVID-19 are incomplete, especially the findings of the chest computed tomography (CT). The aim of the current study was to investigate the severity of the disease of COVID-19 in patients with COPD based on CT severity score and to evaluate its predictive power in the mortality of patients.

The effect of convalescent plasma on the treatment of COVID-19 patients in Ardabil, Iran.

Background: Infection with COVID-19 has resulted in considerable mortality all around the world. This study aimed to investigate the effect of convalescent plasma on the treatment of hospitalized patients with COVID-19 in Imam Khomeini Hospital at Ardabil, Iran.

Materials And Methods: In this quasi-experimental clinical trial, patients over 18 years of age with polymerase chain reaction-positive COVID-19 were admitted based on the clinical criteria of respiratory distress with hypoxia (O saturation <90) and tachypnea (R Relative Risk (RR) >24) with moderate-to-severe lung involvement and in the 1 week of respiratory disease who were not intubated were nonrandomly assigned to two groups: convalescent plasma therapy (CPT) group (197 cases) and control group (200 cases).

Implanting jejunostomy tube as conservative management of tracheoesophageal fistula in a COVID-19 patient.

A 44-year-old woman with Behcet's disease experienced a severe COVID-19 infection and developed a tracheoesophageal fistula. Despite the need for surgical treatment, she did not consent. Therefore, the patient underwent supportive treatment with a jejunostomy tube.

The efficacy of corticosteroids therapy in patients with moderate to severe SARS-CoV-2 infection: a multicenter, randomized, open-label trial.

Background: We performed a multicenter, randomized open-label trial in patients with moderate to severe Covid-19 treated with a range of possible treatment regimens.

Methods: Patients were randomly assigned to one of three regimen groups at a ratio of 1:1:1. The primary outcome of this study was admission to the intensive care unit.
