Rashmi Mishra, Ravi Patel, Misbahuddin Khaja
RATIONALE: Marijuana use has been increasing in the United States among college students and young adults. Marijuana use has been associated with bullous lung disease which can lead to pneumothorax. There are other recreational drugs like methylphenidate, cocaine and heroin which have been associated with pneumothorax. PATIENT CONCERNS: We present a case of a 30-year-old man with spontaneous pneumothorax associated with marijuana use. The patient had no medical conditions and presented to the emergency room with chest pain...

Computer-aided detection (CAD) of lobulation can help radiologists to diagnose/detect lung diseases easily and accurately. Compared to CAD of nodule and other lung lesions, CAD of lobulation remained an unexplored problem due to very complex and varying nature of lobulation. Thus, many state-of-the-art methods could not detect successfully. Hence, we revisited classical methods with the capability of extracting undulated characteristics and designed a sliding window based framework for lobulation detection in this paper...

BACKGROUND: Endometrial stromal sarcomas arising in extrauterine and extraovarian sites, in the absence of a primary uterine lesion are quite rare, especially in the absence of endometriosis. They usually present as an abdominal or pelvic mass lesion. CASE PRESENTATION: In 2007, a 45-year-old woman underwent total hysterectomy for in situ squamous cell carcinoma of the cervix. In 2014, an upper left pulmonary lobectomy was performed for a mass, which was provisionally diagnosed as primary carcinosarcoma of the lung...

OBJECTIVES: Although real-time ultrasound guidance during central venous catheter insertion has become a standard of care, postinsertion chest radiograph remains the gold standard to confirm central venous catheter tip position and rule out associated lung complications like pneumothorax. We hypothesize that a combination of transthoracic echocardiography and lung ultrasound is noninferior to chest radiograph when used to accurately assess central venous catheter positioning and screen for pneumothorax...

BACKGROUND AND AIMS: Obese individuals are predisposed to difficult airway and intubation. They usually yield confusing or misleading auscultatory findings. We aimed to assess the rapidity and efficacy of ultrasonographic (USG) sliding lung sign for confirming endotracheal intubation in normal as well as overweight and obese surgical patients. METHODS: This prospective, observational study was performed in forty surgical patients. Twenty patients with body mass index (BMI) <25 were recruited to Group A, whereas twenty patients with BMI ≥25 constituted Group B...

OBJECTIVE: To explore the reliability and accuracy of lung ultrasound for diagnosing neonatal pneumothorax. METHODS: This study was divided into two phases. (1) In the first phase, from January 2013 to June 2015, 40 patients with confirmed pneumothorax had lung ultrasound examinations performed to identify the sonographic characteristics of neonatal pneumothorax. (2) In the second phase, from July 2015 to August 2016, lung ultrasound was undertaken on 50 newborn infants with severe lung disease who were suspected of having pneumothorax, to evaluate the sonographic accuracy and reliability to diagnose pneumothorax...

BACKGROUND Chronic Granulomatous Disease (CGD) is a rare immunodeficiency disease caused by a genetic defect in the NADPH (nicotinamide adenine dinucleotide phosphate) oxidase enzyme, resulting in increased susceptibility to bacterial and fungal infections. The inheritance can be X-linked or autosomal recessive. Patients usually present with repeated infections early in life. We present an unusual case of a 23-year-old patient diagnosed with CGD. CASE REPORT A 23-year-old white woman with no previous history of recurrent infections presented with complaints of fever, shortness of breath, and diffuse myalgia...

Acute pulmonary emphysema (APE) has been described in cases of mechanical asphyxia such as ligature or manual strangulation but not in cases of hanging. In this study, we wanted to verify by morphometric digital analysis of lung tissue whether APE occurs in death by hanging.We investigated 16 cases of hanging (eight complete, eight incomplete), 10 cases of freshwater drowning (positive control group), and 10 cases of acute external bleeding (negative control group). Tissue sections were obtained from each pulmonary lobe...

BACKGROUND: Increasingly, as in our institution, operating rooms are located in hospitals and the pathology suite is located at a distant location because of off-site consolidation of pathology services. Telepathology is a technology which bridges the gap between pathologists and offers a means to obtain a consultation remotely. We aimed to evaluate the utility of telepathology as a means to assist the pathologist at the time of intraoperative consultation of lung nodules when a subspecialty pathologist is not available to directly review the slide...

For a long time the lung has been regarded as inaccessible to ultrasound. However, recent clinical studies have shown that this organ can be examined by this technique, which appears, in some situations, to be superior to thoracic radiography. The examination does not require special equipment and is possible using a combination of simple qualitative signs: lung sliding, the presence of B lines and the demonstration of the lung point. The lung sliding corresponds to the artefact produced by the movement of the two pleural layers, one against the other...

Video-assisted thoracoscopic surgery for pediatric patients has gained popularity due to better outcomes than open surgery. For this procedure, one-lung ventilation may be necessary to provide an adequate surgical field. Confirming lung isolation is crucial when one-lung ventilation is required. Recently, we experienced a case in which one-lung ventilation was confirmed by ultrasonography using the lung sliding sign and the lung pulse in an infant. Since lung ultrasonography can be performed easily and quickly, it may be a useful method to confirm lung isolation, particularly in emergency surgeries with limited time, devices, and experienced anesthesiologists...

A female northern elephant seal (Mirounga angustirostris) weaned pup presented with malnutrition. During rehabilitation, the seal developed regurgitation and reduced lung sounds on auscultation. Radiographs and endoscopy performed under sedation suggested a diaphragmatic hernia. A Type I (or sliding) hiatal hernia was confirmed with a positive contrast upper gastrointestinal study, revealing varying degrees of herniation of the gastric fundus through the diaphragm into the caudal thorax as well as esophageal reflux...

REVIEW
Daniel A Lichtenstein
This review article describes two protocols adapted from lung ultrasound: the bedside lung ultrasound in emergency (BLUE)-protocol for the immediate diagnosis of acute respiratory failure and the fluid administration limited by lung sonography (FALLS)-protocol for the management of acute circulatory failure. These applications require the mastery of 10 signs indicating normal lung surface (bat sign, lung sliding, A-lines), pleural effusions (quad and sinusoid sign), lung consolidations (fractal and tissue-like sign), interstitial syndrome (lung rockets), and pneumothorax (stratosphere sign and the lung point)...

BACKGROUND: Pneumothorax (PTX) following flexible bronchoscopy (FB) and transbronchial lung biopsy (TBLB) occurs in 1% to 6% of cases. Chest radiography (CXR) is therefore routinely requested to detect PTX following TBLB. The objective of this study was to prospectively evaluate the accuracy of ultrasound (US) in the detection of post-TBLB PTX. METHODS: Consecutive patients undergoing elective FB at a tertiary care hospital were included in the study. A real-time US was used to rule out PTX immediately after FB...

Two cases of diffuse dendriform pulmonary ossification (DPO) are presented, one of the secondary type and the other of the idiopathic type. Case 1 was an adult female patient who underwent thoracic surgery to remove a posterior mediastinal bronchogenic cyst, which was discovered on a computed tomography scan performed after an episode of pneumonia when traction bronchiectasis with interstitial lung disease/fibrosis was also suspected in the lungs. Histologic examination performed on the resected lung tissue revealed numerous scattered small osseous spicules on a background of intense interstitial inflammation and fibrosis, leading to further clinical and laboratory investigations and the final diagnosis of DPO secondary to lung involvement by scleroderma...

Over the past decade, critical care ultrasound has gained its place in the armamentarium of monitoring tools. A greater understanding of lung, abdominal, and vascular ultrasound plus easier access to portable machines have revolutionised the bedside assessment of our ICU patients. Because ultrasound is not only a diagnostic test, but can also be seen as a component of the physical exam, it has the potential to become the stethoscope of the 21st century. Critical care ultrasound is a combination of simple protocols, with lung ultrasound being a basic application, allowing assessment of urgent diagnoses in combination with therapeutic decisions...

BACKGROUND: Medical thoracoscopy (MT) is a diagnostic and therapeutic procedure that permits the study of the pleural space. The presence of pleural adhesions is the most important contraindication to performing MT. Lesions of the pleura in absence of pleural effusion are usually studied in video-assisted thoracoscopic surgery (VATS) with preoperative ultrasound evaluation. No data are available about ultrasound-guided MT in the absence of pleural effusion. METHODS: From January 2007 to June 2013, 622 consecutive MTs were performed under ultrasound guidance without inducing a pneumothorax...
