Described here are a series of four cases of congenital high airway obstruction in the fetus. All of the patients presented in the second trimester and all had hydrops fetalis. Three cases had bilateral hyperinflated lungs, midline shift of heart, flattening or inversion of the diaphragm, and fetal ascites. Autopsy was performed in one of these three and showed laryngeal atresia. In one fetus, there was only a unilateral huge enlargement of the lung with mediastinal shift. On autopsy, this fetus had atresia of right main bronchus...

OBJECTIVES: In the 7th edition of the tumour, node and metastasis staging system, a primary tumour size larger than 5 cm was shifted to Stage II. Therefore, we aimed to evaluate the characteristics and prognostic factors of node-negative non-small cell lung cancer (NSCLC) larger than 5 cm. METHODS: We included 109 patients who underwent curative resection and had pathologically confirmed node-negative NSCLC >5 cm (Group 1). We compared the clinicopathological characteristics and prognosis of these patients with 85 patients with node-positive NSCLC >5 cm (Group 2) and 383 patients who had node-positive NSCLC ≤5 cm (Group 3)...

A 59-year-old male with alcoholic cirrhosis presented to our hospital with an acutely painful umbilical hernia, and 4 mo of exertional dyspnea. He was noted to be tachypneic and hypoxic. He had a massive right sided pleural effusion with leftward mediastinal shift and gross ascites, with a tense, fluid-filled, umbilical hernia. Emergent paracentesis with drain placement and a large volume thoracentesis were performed. Despite improvement in dyspnea and drainage of 15 L of ascitic fluid, the massive transudative pleural effusion remained largely unchanged...

Congenital diaphragmatic hernia (CDH) is a serious birth defect with a significant mortality and morbidity. The current and constant progress in ultrasound techniques has led to the improvement of the prenatal diagnosis of this malformation. CDH is a developmental defect whose etiology is heterogeneous and takes place when the pleuroperitoneal folds and septum transversum fail to converge and fuse. Survival depends on the extent of pulmonary hypoplasia and the disease may be potentially worsened by the presence of added congenital defects...

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...

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...

We report a 5-year boy presenting with pain in the lower chest and upper abdomen. On evaluation with computed tomography scan of the chest, he was found to have a large 16 x 14 cm posterior mediastinal mass compressing the inferior vena cava and liver, and shifting the heart to the opposite side. Tumor was approached via right postero-lateral thoracotomy and dissected off from esophagus, heart, inferior vena cava and lungs. The entire tumor was resected without any complications. Postoperative course was unremarkable...

PTA is a collection of pus located between the tonsillar capsule and the pharyngeal constrictor muscle. It is considered a complication of acute tonsillitis and is the most prevalent deep neck infection (approximately 2000 cases annually in Denmark) and cause of acute admission to Danish ENT departments. Teenagers and young adults are most commonly affected and males may predominate over females. However, no studies of age- and gender-stratified incidence rates have previously been published. Furthermore, smoking may be associated with increased risk of peritonsillar abscess (PTA) development, although the magnitude of the association has not been estimated...

In recent years, the myocardium has been rediscovered under the lenses of immunology, and lymphocytes have been implicated in the pathogenesis of cardiomyopathies with different etiologies. Aging is an important risk factor for heart diseases, and it also has impact on the immune system. Thus, we sought to determine whether immunological activity would influence myocardial structure and function in elderly mice. Morphological, functional, and molecular analyses revealed that the age-related myocardial impairment occurs in parallel with shifts in the composition of tissue-resident leukocytes and with an accumulation of activated CD4(+) Foxp3(-) (forkhead box P3) IFN-γ(+) T cells in the heart-draining lymph nodes...

PURPOSE: The purpose of this study was to estimate the uncertainty in voluntary deep-inspiration breath-hold (DIBH) radiotherapy for locally advanced non-small cell lung cancer (NSCLC) patients. METHODS: Perpendicular fluoroscopic movies were acquired in free breathing (FB) and DIBH during a course of visually guided DIBH radiotherapy of nine patients with NSCLC. Patients had liquid markers injected in mediastinal lymph nodes and primary tumours. Excursion, systematic- and random errors, and inter-breath-hold position uncertainty were investigated using an image based tracking algorithm...

BACKGROUND: Inflammatory responses play a critical role in left ventricular remodeling after myocardial infarction (MI). Tolerogenic dendritic cells (tDCs) can modulate immune responses, inducing regulatory T cells in a number of inflammatory diseases. METHODS: We generated tDCs by treating bone marrow-derived dendritic cells with tumor necrosis factor-α and cardiac lysate from MI mice. We injected MI mice, induced by a ligation of the left anterior descending coronary artery in C57BL/6 mice, twice with tDCs within 24 hours and at 7 days after the ligation...

OBJECTIVES: The aim of this study was to follow the course of the superior mesenteric artery (SMA) in first-trimester fetuses to predict the location of the small bowel. Its abnormal course aids in early detection of congenital diaphragmatic hernia (CDH) and assessment of the contents of omphalocele. METHODS: The SMA can be easily identified in a sagittal section of the fetus by using color Doppler sonography at the 11- to 14-week scan, and normally, it has a downward course caudally to supply the intestines...

BACKGROUND: Tension gastrothorax is a kind of obstructive shock with prolapse and distention of the stomach into the thoracic cavity. Progressive gastric distension leads to mediastinal shift, reduced venous return, decreased cardiac output, and ultimately cardiac arrest. Therefore, it is crucial to decompress the stomach distension for the initial resuscitation of tension gastrothorax.

BACKGROUND Mechanical ventilation strategies for one lung ventilation (OLV) differ from conventional modalities in that it can adapt to greater degrees of ventilation/perfusion (V/Q) mismatch. We present a case of cancer causing complete unilateral endobronchial obstruction with refractory hypoxia that improved with OLV strategy. CASE REPORT Our patient was an elderly male, admitted to our intensive care unit (ICU) on mechanical ventilation with worsening hypoxic respiratory failure secondary to lung mass and post-obstructive atelectasis...

A 55-year-old wheelchair-bound woman with severe cerebral palsy was found at autopsy to have marked distention of the stomach due to a volvulus. The stomach was viable, and filled with air and fluid and had pushed the left dome of the diaphragm upwards causing marked compression of the left lung with a mediastinal shift to the right (including the heart). There was no evidence of gastric perforation, ischaemic necrosis or peritonitis. Removal of the organ block revealed marked kyphoscoliosis. Histology confirmed the viability of the stomach and biochemistry showed no dehydration...

We report a case of congenital diaphragmatic hernia (CDH) with perinatal bowel strangulation requiring intestinal resection. Ten hours after birth, the newborn started to be lethargic and developed bilious emesis. X-ray documented distended loops of bowel with air fluid levels in the abdomen and a gasless, non-homogeneous opacity of the left hemithorax, a right mediastinal shift and loss of the sharp left hemidiaphram line. On gastrographin enema the left colon was above the adjacent left diaphragm. Emergency surgery was performed at 16 h of age...

Anesthetic management of the child with an anterior mediastinal mass is challenging. The surgical/procedural goal typically is to obtain a definitive tissue diagnosis to guide treatment; the safest approach to anesthesia is often one that alters cardiorespiratory physiology the least. In severe cases, this may translate to little or no systemic sedatives/analgesics. Distraction techniques, designed to shift attention away from procedure-related pain (such as counting, listening to music, non-procedure-related talk), may be of great benefit, allowing for avoidance of pharmaceuticals...

A 22-year-old man presented to a rural hospital in Australia with right-sided pleuritic chest pain, right shoulder pain and dyspnoea. The patient had been receiving chronic asthma therapy without improvement. CT of the chest was performed after an abnormal X-ray, incidentally revealing one of the largest documented right-sided diaphragmatic hernias, with left lung compression due to mediastinal shift. The patient was definitively managed with thoracotomy alone. The contents of the hernia sac included colon and multiple loops of small bowel with a 10 cm neck...
