We report a case of spontaneous pneumomediastinum with unusual clinical presentation. The most common symptoms of spontaneous mediastinum are chest pain and shortness of breath. Our patient presented with neck swelling and change in voice, an unusual presentation for spontaneous pneumothorax. A 30-year-old previously healthy man presented with complaints of neck swelling and hoarseness of voice beginning after an intense coughing spell. He had no other complaints. He denied any trauma to the chest, nausea, vomiting, recent air travel, scuba diving or recreational drug use...

PURPOSE: CT-guided percutaneous transthoracic lung needle biopsy (PLB) is an effective procedure for obtaining cyto-histological diagnoses of peripheral lesions. However, upper postero-lateral lung nodules (UPLN) may be difficult to reach using a standard intercostal either anterior or lateral approach or when the nodule is just behind a rib or scapula. We evaluated the feasibility and effectiveness of trans-scapular approach (tPLB) in these patients using large-core needles. METHODS: We retrospectively collected the data of 11 consecutive patients (mean age 74...

BACKGROUND: Birt-Hogg-Dube syndrome (BHDS) is an autosomal dominant disease characterized by hair follicle hamartomas, kidney tumors, and spontaneous pneumothorax; its cause is a heterozygous mutation in the FLCN gene. Colorectal polyps and carcinoma have also been reported in BHDS. FLCN mutations can be detected in patients with isolated primary spontaneous pneumothorax (PSP), so PSP may present as part of BHDS. The aim of this report is to enhance awareness that patients presenting with spontaneous PSP should be evaluated for FLCN mutations...

OBJECTIVE: Foreign body aspiration (FBA) could be a serious life-threatening condition in children. Patients usually underwent bronchoscopy with suspicious of FBA alone. In this study, we aimed to determine which patients need to go to bronchoscopy based on pre-operative findings. METHODS: Retrospective analysis of patients underwent bronchoscopy between 1999 and 2015 was performed. Clinical symptoms, witnessed aspiration event (WAE), physical examination findings (PEFs) and radiological findings (RFs) were analyzed by multivariate analysis to evaluate the indications of bronchoscopy...

OBJECTIVE: The National Institute for Occupation Safety and Health-administered Coal Workers' Health Surveillance Program (CWHSP) provides radiographic pneumoconiosis screening for US coal miners. Radiographs are classified by readers according to International Labour Office criteria. In addition to pneumoconiotic parenchymal and pleural lung abnormalities, readers document radiographic features of importance (other symbols). Other symbols are not meant to imply a diagnosis or interpretation but are relevant as they provide information beyond a pneumoconiosis classification for features related to dust exposure and other aetiologies...

RATIONALE AND OBJECTIVES: This study aimed to determine the value of dual-energy thoracic radiography in the diagnosis of pneumothorax considering the reader's experience. MATERIALS AND METHODS: Forty patients with a suspected pneumothorax, imaged with dual-energy chest radiographs, were divided into two groups: those with pneumothorax as the final diagnosis (n = 19) and those without (n = 21). The images were analyzed by 36 readers (5 interns, 16 residents, 15 senior physicians) for the presence or absence of pneumothorax during three readout sessions at 2-week intervals: standard images alone (session 1), dual-energy images with bone subtraction alone (session 2), and a combination of the two (session 3)...

Esophageal atresia (EA) is a rare anomaly that mandates surgical intervention. Patients with EA often have complicated medical courses due to both esophageal anomalies and related comorbidities. Although several prognostic classification systems have been developed to decrease the mortality rate in EA, most systems focus only on the influence of the major anomaly, and external risk factors that could be influenced by the neonatal caregivers to a certain extent are not included. The aim of this study was to investigate the risk factors for in-hospital mortality in neonates with EA and develop a scoring model to predict mortality...

BACKGROUND: In chemical pleurodesis for managing pulmonary air leak, tetracycline derivatives are commonly used, and their effectiveness has been established in many studies. Recently, a Viscum album extract was used in chemical pleurodesis. We compared the effects of V. album with those of a tetracycline derivative (doxycycline) to demonstrate the therapeutic effectiveness of the V. album extract in chemical pleurodesis for managing pulmonary air leak. METHODS: Between October 2010 and October 2016, chemical pleurodesis was performed using doxycycline in 40 patients and the V...

A patient with pulmonary alveolar proteinosis underwent whole lung lavage of the right lung. Lavage of the left lung was not immediately possible because of severe hypoxemia. Three days later, after correction of hypoxemia, we re-attempted the left lung lavage. However, the patient had severe hypoxemia (SpO2 < 80%) within a few minutes of performing right one lung ventilation (OLV). On bronchoscopic examination, proper tube location was confirmed. Bronchodilator nebulization and steroid injection were attempted with no effect...

BACKGROUND AND AIMS: The supraclavicular and infraclavicular brachial plexus blocks have a similar distribution of anaesthesia, and both can be used effectively for surgeries of the upper limb. This study aimed to compare the supraclavicular and infraclavicular approaches of brachial plexus blocks, guided by ultrasound and neurostimulation. METHODS: Sixty adult patients scheduled for elective upper limb surgery of the elbow and/or below were randomly divided into two groups: infraclavicular Group (I) and supraclavicular Group (S)...

Tension pneumothorax, a major preventable cause of battlefield death, often arises from chest trauma and is treated by needle decompression to release trapped air from the pleural cavity. Surgical simulation mannequins are often employed to train medical personnel to perform this procedure properly. Accurate reproduction of the mechanical behavior of the parietal pleura, especially in response to needle penetration, is essential to maximize the fidelity of these surgical simulators. To date, however, the design of pleura-simulating material has been largely empirical and based on subjective practitioner feel rather than on the tissue properties, which have remained unknown...

The extrapleural space (EPS) is an anatomic space at the periphery of the chest that can be involved in a number of disease processes. This space lies between the inner surface of the ribs and the parietal pleura and contains adipose tissue, loose connective tissue, lymph nodes, vessels, endothoracic fascia, and the innermost intercostal muscle. It is often overlooked on cross-sectional imaging studies and almost invariably overlooked on conventional radiographic studies. At conventional radiography, the EPS occasionally can be seen when there is extrapleural fat proliferation, which might be confused with pleural thickening or pleural effusion...

Tension pneumopericardium is a rare disease that is very difficult to diagnose. A 3-year old child was run over by a minibus. Computed tomography showed bilateral pneumothorax, multiple rib fractures on both sides, and a hepatic laceration. The massive blunt thoracic trauma caused entrapped air in the pericardium, and a tension pneumoprecordium developed abruptly. We report this unique case of tension pneumopericardium in a child, and the subsequent emergency surgery and damage control measures.

Spontaneous pneumothorax (SP) is a non-traumatic accumulation of air in the pleural cavity. This case report describes a cat with SP as a result of primary pulmonary adenocarcinoma. A second cat was diagnosed with primary pulmonary adenocarcinoma and asthma. A thoracostomy tube was inserted in the first cat while in the second cat a thoracostomy tube was placed and lobectomy of the right cranial and middle lung lobes was performed. Both cats died following treatment. The current literature reviewed here covers the comparative etiologies of SP as well as clinical presentation, diagnostic work-up, therapy and prognosis in cats...

Pneumothorax contralateral to the venous access site due to the right atrial lead is an uncommon complication. Concomitant steroid use is known as a risk factor of pacemaker lead perforation. We report a rare case of subacute contralateral pneumothorax due to a screw-in atrial lead perforation that occurred after dual-chamber pacemaker implantation in a patient who was receiving steroid therapy. The pneumothorax disappeared, and no recurrence was observed during follow-up with close observation alone.
