Boerhaave's syndrome is a rare yet serious condition associated with high mortality and morbidity. Diagnosis of this syndrome is usually done with the aid of imaging and prompt management should be initiated to improve the outcomes. Treatment for this syndrome has been mainly surgical since its discovery by Herman Boerhaave; however, multiple endoscopic approaches have been successfully used recently with the advancement of this field.

Background: Effective first aid on the battlefield is vital to minimize deaths caused by war trauma and improve combat effectiveness. However, it is difficult for junior medical students, which have relatively poor human anatomy knowledge and first aid experience. Therefore, we aim to create a treatment simulation software for war trauma, and to explore its application for first aid training. Read More

Purpose: Owing to the extent of lung collapse estimated on chest radiograph it is still the complementary test most commonly used in the management of patients with pneumothorax. There are several indices to assess the extent of lung collapse. The objective of this study was to develop a more accurate index, using the 3D printing technology. Read More

Purpose: To describe the imaging findings of COVID-19 and correlate them with their known pathology observations.

Methods: This is an IRB-approved retrospective study performed at Columbia University Irving Medical Center () that included symptomatic adult patients (21 years or older) who presented to our emergency room and tested positive for COVID-19 and were either admitted or discharged with at least one chest CT from 11 March 2020 through 1 July 2020.

During the last five decades, lung sonography has developed into a core competency of intensive care medicine. It is a highly accurate bedside tool, with clear diagnostic criteria for most causes of respiratory failure (pneumothorax, pulmonary edema, pneumonia, pulmonary embolism, chronic obstructive pulmonary disease, asthma, and pleural effusion). It helps in distinguishing a hypovolemic from a cardiogenic, obstructive, or distributive shock. Read More

Background: Cryobiopsy is an established technique that yields larger and higher-quality samples than does a forceps biopsy. However, it remains underutilised in the diagnosis of peripheral pulmonary lesions (PPLs), mainly because of difficulties in handling conventional cryoprobes. A recently introduced single-use cryoprobe with a smaller diameter and more flexibility than conventional ones may improve its diagnostic ability for PPLs. Read More

Fine-needle aspiration biopsy is the most common method for preoperative diagnosis of thyroid carcinomas including papillary carcinoma. The procedure is best performed with ultrasound by operator with professional skill and knowledge. Several guidelines recommend the indication of fine-needle aspiration concerning the pattern of ultrasound and size of nodules. Read More

Background: Human immunodeficiency virus/tuberculosis coinfections have amplified the multidrug-resistant tuberculosis pandemic in many countries in Sub-Saharan Africa, and multidrug-resistant tuberculosis has become a major public health threat. There is a paucity of data on severe complications of multidrug-resistant tuberculosis in the context of human immunodeficiency virus coinfection despite the increasing prevalence of multidrug-resistant tuberculosis/human immunodeficiency virus coinfection and the complexity of multidrug-resistant tuberculosis treatment. This report describes a rare case of complicated multidrug-resistant tuberculosis in a human immunodeficiency virus-positive individual. Read More

Chlorine is an irritant gas, which is implicated in inhalational exposures and can affect the respiratory system leading to complications. We report a case of a 38-year man who presented in the Emergency Department (ED) after exposure to chlorine gas due to an industrial accident. During the course of ED stay, he developed gradual difficulty in breathing, which on investigation, was found to be related to the complication of pneumomediastinum. Read More

In recent years, lung disease has increased manyfold, causing millions of casualties annually. To combat the crisis, an efficient, reliable, and affordable lung disease diagnosis technique has become indispensable. In this study, a multiclass classification of lung disease from frontal chest X-ray imaging using a fine-tuned CNN model is proposed. Read More

Ultrasound imaging is essential in emergency medicine and combat casualty care, oftentimes used as a critical triage tool. However, identifying injuries, such as shrapnel embedded in tissue or a pneumothorax, can be challenging without extensive ultrasonography training, which may not be available in prolonged field care or emergency medicine scenarios. Artificial intelligence can simplify this by automating image interpretation but only if it can be deployed for use in real time. Read More

Objectives: To evaluate the safety, effectiveness and cost-benefit of ambulatory pleural vent compared to conventional chest drain for pneumothorax following CT-guided biopsy of lung lesions (CTGB).

Methods: We retrospectively analysed electronic hospital records of patients requiring intervention for pneumothorax following CTGB. All patients treated with pleural vent over a 2-year period (August 2017-July 2019) were included and compared to a control group of all patients treated with chest drain over a previous 2-year period (August 2014-July 2016).

Background: The horizontal beam (HB) view has been used in the identification of pneumothorax, pleural effusion, and pneumoperitoneum in small animals. Based on the literature, there were no published data evaluating the utility of HB radiography in vomiting dogs to differentiate between patients with or without mechanical gastrointestinal ileus.

Aim: The purpose of this prospective pilot study was to determine the utility of HB radiograph as an additional view in vomiting dogs to differentiate patients with or without mechanical gastrointestinal ileus; and describe if there are any radiographic image characteristics associated with the HB view for patients with mechanical gastrointestinal ileus.

In the setting of acute trauma where identification of critical injuries is time-sensitive, a portable chest radiograph is broadly accepted as an initial diagnostic test for identifying benign and life-threatening pathologies and guiding further imaging and interventions. This article describes chest radiographic findings associated with various injuries resulting from blunt chest trauma and compares the efficacy of the chest radiograph in these settings with computed tomography (CT). Common chest radiographic findings in blunt thoracic injuries will be reviewed to improve radiologic identification, expedite management, and improve trauma morbidity and mortality. Read More

Division of Pulmonary and Critical Care Medicine, Department of Internal Medicine, Chungnam National University Hospital, Daejeon, Republic of Korea.

Objectives: Delayed pneumothorax can cause an emergency room visit and be life-threatening in case of tension pneumothorax after transthoracic needle biopsy. We hypothesized that most delayed pneumothoraces are diagnosed by later enlargement of occult pneumothorax due to the low diagnostic accuracy of a chest X-ray. Lung ultrasound is a highly accurate tool for detection of pneumothorax. Read More

Department of Radiology, University Hospitals Cleveland Medical Center/Case Western Reserve University School of Medicine, Cleveland, OH, USA.

Tension gastrothorax is a rare, life-threatening clinical condition caused by intrathoracic herniation of the stomach through a diaphragmatic defect which becomes increasingly distended over time. If not recognized promptly, this can rapidly progress to respiratory distress, mediastinal shift, and hemodynamic compromise. Initial clinical presentation and imaging findings closely mirror those of tension pneumothorax, confounding diagnosis and potentially leading to unnecessary interventions with increased risk of morbidity and mortality.

BMJ Mil Health 2022 May 18. Epub 2022 May 18.

Emergency Department, Brighton and Sussex University Hospitals NHS Trust, Worthing, UK.

Background: Tension pneumothorax following trauma is a life-threatening emergency and radiological investigation is normally discouraged prior to treatment in traditional trauma doctrines such as ATLS. Some trauma patients may be physiologically stable enough for diagnostic imaging and occult tension pneumothorax is discovered radiologically. We assessed the outcomes of these patients and compared them with those with clinical diagnosis of tension pneumothorax prior to imaging. Read More
