BACKGROUND: Delayed recognition of tension pneumothorax can lead to a mortality of 31% to 91%. However, the classic physical examination findings of tracheal deviation and distended neck veins are poorly sensitive in the diagnosis of tension pneumothorax. Point-of-care ultrasound is accurate in identifying the presence of pneumothorax, but sonographic findings of tension pneumothorax are less well described. CASE REPORT: We report the case of a 21-year-old man with sudden-onset left-sided chest pain...

BACKGROUND: Atypical carcinoid arising from the mediastinal tissue is a rare neuroendocrine tumor and an association with parathyroid adenoma is very unusual. We report an unusual case of atypical carcinoid of mediastinum with metastasis in a patient presenting with parathyroid adenoma, which is the first case to be reported from Pakistan. CASE PRESENTATION: A 51-year-old Pakistani man was seen in postoperative intensive care after right parathyroidectomy and mediastinal mass resection for the management of postoperative hypocalcaemia...

In spite of difficult anatomic access for tumors of mediastinum, surgical resection remains the best diagnostic and therapeutic approach. Widespread acceptance of video-assisted thoracoscopy (VATS) is restricted by the limiting nature of instruments and suboptimal visualization. Robotic assisted minimally invasive surgery seems to hold most promise in remote, narrow anatomical regions. After obtaining approval from Institutional Review Board (IRB), a retrospective review of prospectively collected database on patients that underwent Robotic VATS between 2009 and 2013 was conducted...

Purpose. Radiation-induced lung fibrosis (RILF) is a serious late complication of radiotherapy. In vitro studies have demonstrated that pentoxifylline (PTX) has suppressing effects in extracellular matrix production in fibroblasts, while the antifibrotic action of PTX alone using clinical dose is yet unexplored. Materials and Methods. We used micro-computed tomography (micro-CT) and histopathological analysis to evaluate the antifibrotic effects of PTX in a rat model of RILF. Results. Micro-CT findings showed that lung density, volume loss, and mediastinal shift are significantly increased at 16 weeks after irradiation...

Combination of sedatives such as fentanyl and midazolam during bronchoscopy is recommended by American College of Chest Physician due to its favourable drug profile. It improves patient comfort and tolerance, and is commonly given unless contraindicated. We describe a rare case of fentanyl-induced chest wall rigidity syndrome during a routine bronchoscopy with endobronchial ultrasound guided-transbronchial needle aspiration (EBUS-TBNA) in a 55 year old male presenting with a lung mass and mediastinal lymphadenopathy...

A twelve-year-old male castrated domestic shorthair cat was presented for rapidly progressing respiratory distress. The cat was depressed, tachypneic and moderately responsive. Ultrasonography showed a mediastinal mass associated with a significant pleural effusion that needed tapping every five to seven days. Ultrasound guided biopsy yielded a diagnosis of clear cell thymoma upon histopathology. After complete staging procedures, the owner elected to treat the cat with electrochemotherapy (ECT) using systemic bleomycin...

BACKGROUND: Spontaneous pneumomediastinum is defined as the presence of free air in the mediastinum without any apparent concomitant factors or disease. It is uncommon but usually benign and self-limiting. Generally, patients with spontaneous pneumomediastinum are admitted to hospital, and occasionally, prophylactic antibiotics are administered to prevent mediastinitis. The purpose of this study was to describe practices concerning the feasibility of outpatient treatment and follow-up of spontaneous pneumomediastinum and the necessity of prophylactic antibiotics...

Peripheral tolerance is crucial for avoiding activation of self-reactive T cells to tissue-restricted antigens. Sterile tissue injury can break peripheral tolerance, but it is unclear how autoreactive T cells get activated in response to self. An example of a sterile injury is myocardial infarction (MI). We hypothesized that tissue necrosis is an activator of dendritic cells (DCs), which control tolerance to self-antigens. DC subsets of a murine healthy heart consisted of IRF8-dependent conventional (c)DC1, IRF4-dependent cDC2, and monocyte-derived DCs...

Sclerosing mediastinitis (SM) is an aggressive fibroproliferative process in the mediastinum that may lead to encasement of mediastinal structures within a dense fibrotic mass. This disease may cause significant clinical complications, morbidity, and even mortality. The etiology and pathogenesis of SM is unclear and in more than one third of cases remains idiopathic. Among the known causes of SM, granulomatous infection is the commonest. Association of SM with radiation therapy has been rarely reported. Herein, we are reporting a case of postradiation sclerosing mediastinitis diagnosed in fine needle aspiration (FNA) specimen...

A previously healthy man, who had undergone coronary artery bypass 10 years earlier and had been diagnosed with brucellosis due to Brucella septicemia after Brucella arthritis, presented with chest pain and high fever. Anti- Brucella antibiotics were started, but after 4 weeks, his high fever remained. An infected mass was confirmed by computed tomography, and surgical intervention was performed via a median sternotomy. A large amount of thick pus gushed from an abscess in the upper mediastinum. The abscess cavity had a thick granulation wall, and cultured pus was positive for Brucella only...

BACKGROUND: We believe the merit of preservation of a part of the thymus following surgery for thymoma. We evaluated the efficacy of partial or subtotal thymectomy for early-stage thymoma in the prospective study. METHODS: The Japanese Association for Research on the Thymus conducted a multiple institutional study of thymectomy for thymoma localized in the thymus without total thymectomy. Patients without autoimmune disease who had an anterior mediastinal tumor that had been clinically diagnosed as an early-stage thymoma were enrolled in the study...

Stereotactic body radiotherapy (SBRT) is an effective method for the treatment of localized primary lung tumors. Cyberknife, a highly accurate SBRT technique, follows the target during respiratory cycles using a metallic fiducial marker (FM) previously inserted into the lesion. Various methods have been described for the placement of an FM in peripheral pulmonary lesions; however, none of these is appropriate for mediastinal or hilar tumors. The placement of FMs in central lesions to achieve accurate SBRT is particularly relevant due to their higher mobility during respiratory and cardiac cycles...

Malignant neoplasms frequently cause vertebral metastases. Traditionally, either image-guided percutaneous biopsy or open biopsy has been performed for sampling specimens for the definitive diagnosis. We herein report a case with suspected multiple metastases but unknown primary, who underwent endobronchial ultrasound-guided transbronchial needle aspiration for mediastinal lymph nodes with negative results by rapid onsite cytologic evaluation, followed by the transesophageal approach with the ultrasound bronchoscope for the vertebral body lesion at the same setting that provided a definitive diagnosis of metastatic hepatocellular carcinoma...
