Relapse of Lymphangioleiomyomatosis Five Years after Bilateral-Lung Transplantation.

Pulmonary lymphangioleiomyomatosis (LAM) is an uncommon disease principally affecting women during childbearing years and eventually leading to progressive respiratory failure. Lung transplantation is a viable option for patients with end-stage disease. LAM-related complications remain common, but recurrence of LAM following allograft transplantation is rare.

Not all that is miliary is tuberculosis: Metastatic medullary thyroid carcinoma mimicking miliary tuberculosis.

Medullary carcinoma of the thyroid should be considered in the differential diagnosis of miliary pattern of micronodules on chest imaging, irrespective of clinical features.

Radiological and Laboratory Findings of Patients with COVID-19 Infection at the Time of Admission.

Background & Objective: Diagnosis of coronavirus disease 2019 (COVID-19) can be challenging, especially when the real-time quantitative reverse transcription polymerase chain reaction (RT-PCR) is not available or it is negative. In this study, we evaluated imaging and laboratory findings in a group of patients with a multidisciplinary diagnosis of COVID-19 pneumonia.

Methods: A total of 163 patients with a clinical diagnosis of COVID-19 pneumonia admitted to a specialised respiratory centre in Tehran, Iran were enrolled in this study.

ACE2: Its potential role and regulation in severe acute respiratory syndrome and COVID-19.

COVID-19, a new disease caused by the 2019-novel coronavirus (SARS-CoV-2), has swept the world and challenged its culture, economy, and health infrastructure. Forced emergence to find an effective vaccine to immunize people has led scientists to design and examine vaccine candidates all over the world. Until a vaccine is developed, however, effective treatment is needed to combat this virus, which is resistant to all conventional antiviral drugs.
