Teratomas of anterior mediastinum are rare. They are often slow growing, asymptomatic, and detected incidentally on chest imaging. Mycobacterium abscessus (M. abscessus) is an acid‐fast bacillus that is classified as a pathogenic “rapid growing” non‐tuberculous mycobacteria. It is an uncommon cause of human pathology, which may cause skin and soft tissue infection after skin injury following inoculation, minor trauma, and surgery. Here, we present an unusual case of benign cystic teratoma mimicking recurrent pleural effusion, which was subsequently complicated by M. abscessus infection following thoracotomy. Cystic teratoma is rare, but it needs to be considered whenever clinical and investigative work‐up fails to provide a convincing diagnosis. A combined clinical, radiological, surgical, and histopathological assessment is important to arrive at the correct diagnosis. Rapidly growing mycobacteria needs to be included in the differential diagnosis of patients with non‐resolving infected post‐thoracotomy wound and who do not respond to broad‐spectrum antibiotics.
We report the case of a 50-year-old man who was investigated for an incidental finding of a left lung mass following left shoulder pain over a three month period. He also had a significant raised serum alpha-fetoprotein (AFP) level of 29,000, which raised the suspicion of hepatocellular carcinoma with lung metastases. However, there was no detectable liver lesion on multiphase contrasted tomography of the liver and no significant hypermetabolic nodes or distant metastasis seen in the liver on positron emission tomography scan. A lung biopsy confirmed adenocarcinoma with hepatocellular differentiation that would explain the raised serum AFP level.
Tracheal tear after endotracheal intubation is extremely rare. The role of silicone Y-stent in the management of tracheal injury has been documented in the previous studies. However, none of the studies have mentioned the deployment of silicone Y-stent via rigid bronchoscope with the patient solely supported by extracorporeal membrane oxygenation (ECMO) without general anaesthesia delivered via the side port of the rigid bronchoscope. We report a patient who had a tracheal tear due to endotracheal tube migration following a routine video-assisted thoracoscopic surgery sympathectomy, which was successfully managed with silicone Y-stent insertion. Procedure was done while she was undergoing ECMO; hence, no ventilator connection to the side port of the rigid scope was required. This was our first experience in performing Y-stent insertion fully under ECMO, and the patient had a successful recovery.
Chronic obstructive pulmonary disease (COPD) is significant cause of morbidity and mortality worldwide. There is mounting evidence suggesting that COPD patients are at increased risk of severe COVID-19 outcomes; however, it remains unclear whether they are more susceptible to acquiring SARS-CoV-2 infection. In this comprehensive review, we aim to provide an up-to-date perspective of the intricate relationship between COPD and COVID-19. We conducted a thorough review of the literature to examine the evidence regarding the susceptibility of COPD patients to COVID-19 infection and the severity of their disease outcomes. While most studies have found that pre-existing COPD is associated with worse COVID-19 outcomes, some have yielded conflicting results. We also discuss confounding factors such as cigarette smoking, inhaled corticosteroids, and socioeconomic and genetic factors that may influence this association. Furthermore, we review acute COVID-19 management, treatment, rehabilitation, and recovery in COPD patients and how public health measures impact their care. In conclusion, while the association between COPD and COVID-19 is complex and requires further investigation, this review highlights the need for careful management of COPD patients during the pandemic to minimize the risk of severe COVID-19 outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
