Abstract Background We diagnosed a clinical case of pulmonary infection involving Mycobacterium tuberculosis and Tropheryma whipplei in a patient with acute respiratory distress syndrome. The diagnosis was assisted by metagenomic next-generation sequencing of bronchoalveolar lavage fluid. Case presentation A 44-year-old Han Chinese inmate was transferred to the emergency department because of dry cough, chest tightness, and shortness of breath. The patient’s body temperature rose to 39.3 °C following empirical cephalosporin treatment for 1 week. The blood CD4+/CD8+ ratio was 0.7, suggesting immunodeficiency. Routine microbiological tests were performed, and tuberculosis interferon gamma release assays were positive. Mycobacterium tuberculosis polymerase chain reaction was also positive. Chest computed tomography scan revealed miliary nodules and ground-glass opacifications, which were in accordance with tuberculosis. To fully examine the etiology, we performed routine laboratory tests and metagenomic sequencing, the results of which indicated the presence of Mycobacterium tuberculosis and Tropheryma whipplei. We administered anti-tuberculosis regimen in combination with trimethoprim/sulfamethoxazole. The patient recovered, with chest computed tomography scan showing absorption of lesions. Conclusions Compared with traditional diagnostic methods such as culture and serology, metagenomic next-generation sequencing has the advantage of detecting a wide array of microorganisms in a single test and therefore can be used for clinical diagnosis of rare pathogens and microbial coinfections. It is particularly useful for immunocompromised patients as they are more prone to infection by opportunistic microorganisms.

Background Currently, there are limited data available describing the long-term outcomes of chest trauma survivors. Here, the authors sought to describe chest trauma survivor outcomes 6 months and 1 yr after discharge from the intensive care unit, paying special attention to pulmonary outcomes. Methods A cohort of 105 multiple trauma patients with blunt chest trauma admitted to the intensive care unit was longitudinally evaluated. After 6 months, a chest computed tomography scan, pulmonary function testing (PFT), and quality of life were collected in 55 of these patients. A subgroup of 38 patients was followed up for 1 yr. Results At least one abnormal PFT result was found in 39 patients (71%). Compared with normalized data of the age- and sex-matched population, physical function was decreased in 38 patients (70%). The 6-min walk distance was reduced for 29 patients (72%). Although pathologic images were observed on the chest computed tomography scan from 33 patients (60%), no relation was found between PFT and computed tomography. A ratio of arterial oxygen pressure to inspired oxygen fraction less than 200 at admission to the intensive care unit predicted an abnormal PFT result at 6 months. One year after discharge from the intensive care unit, paired comparisons showed a significant increase in forced vital capacity (P = 0.02) and Karnofsky Performance Status (P < 0.001). Conclusions Survivors of multiple traumas including chest trauma demonstrate a persistent decrease in the 6-min walk distance, impairment on PFT, and reduced pulmonary-specific quality of life.

A ‘crazy-paving’ appearance of the lungs on computed tomography scanning of the chest was first described nearly 20 years ago in patients with pulmonary alveolar proteinosis, and was thought to be characteristic of this condition. However, this pattern has subsequently been reported in a variety of pulmonary diseases and is now considered to be nonspecific. The present report describes a case of a 74-year-old man in whom congestive heart failure presented with a crazy-paving appearance of the lungs on a chest computed tomography scan. This uncommon association illustrates the importance of the correlation of clinical and radiographic information.

Neonatal management of severe quadricuspid truncal valve insufficiency is very challenging with high risk of postoperative mortality. Aortic valve reconstruction is the unique rescue and should be consider and previously planned in case of truncal valvuloplasty failure. Many extracardiac malformations can be associated to truncus arteriosus, therefore a cardiac and chest computed tomography scan must be performed before the elective surgical repair.
