Although widely validated, current tests for pulmonary embolism (PE) diagnosis, i.e. computed tomography pulmonary angiography (CTPA) and V/Q planar scintigraphy, have some limitations. Drawbacks of CTPA include the radiation dose, some contra indications and a rising concern about a possible overdiagnosis/overtreatment of PE. On the other hand, V/Q planar scintigraphy has a high rate of non-diagnostic tests responsible for complex diagnostic algorithms. Since the PIOPED study, imaging equipment and radiopharmaceuticals have greatly evolved allowing the introduction of techniques that improve imaging of lung ventilation and perfusion...

OBJECTIVE: Discrimination against women training in medicine and surgery has been subjectively described for decades. This study objectively documents gender differences in the degree of autonomy given to thoracic surgery trainees in the operating room. DESIGN: Thoracic surgery residents and faculty underwent frame of reference training on the use of the 4-point Zwisch scale to measure operative autonomy. Residents and faculty then submitted evaluations of their perception of autonomy granted for individual operations as well as operative difficulty on a real-time basis using the "Zwisch Me!!" mobile application...

This study in a regional hospital setting found a low evaluation rate for osteoporosis among patients presenting with a rib fracture. Increased emphasis or education for osteoporosis evaluation may be necessary in case of rib fractures. INTRODUCTION: Rib fractures from a low-energy trauma are common in the elderly, and a history of rib fracture has been reported to increase the risk for a subsequent osteoporotic fracture. The purpose of this study was to evaluate how many of the patients presenting with an isolated rib fracture were being evaluated for osteoporosis and the risk for a subsequent fracture...

The collection of clinical treatment data in registry databases is an important aspect of health services research. It allows for a critical evaluation of the safety, efficacy and cost-effectiveness of clinical treatment concepts in large patient populations. The findings of registry research represent real-world patients and treatment structures as they are not limited by strict inclusion criteria or unrealistic conditions as applied in prospective clinical trials. The implementation of the German Thorax Registry has enabled the collection and analysis of data on the interdisciplinary care (thoracic surgery, anaesthesiology, intensive care, pain management) of patients undergoing thoracic surgery...

Little information has been available regarding microanatomy of human thoracic duct in spite of the importance for an understanding of pathophysiology in clinical medicine. The present study demonstrated a fine structure of human thoracic duct system by light and scanning electron microscopy. A number of longitudinal or spiral ridges and grooves were formed on luminal surfaces of the lymphangia and lymph sac, it likely facilitating fluent lymph flow. The endothelial cells displayed various cell shapes in compliance with their distributed regions...

Diaphragm is the principal respiratory muscle. Diaphragm dysfunction resulting from mechanical ventilation, chronic cardiopulmonary disease, medicine, cardio-thoracic surgery, septic shock and chronic malnutrition predisposes to weaning failure from mechanical ventilation and prolongs intensive care unit (ICU) stay. Traditionally, the method of assessment of diaphragm structure and function was invasive, lacking specific, and was difficult to be used bedside. A number of recent studies have been suggested that ultrasonographic evaluation has been proposed as an accurate, safe and noninvasive method of quantification of diaphragm structure and function...

Obesity and its association with long-term health problems constitutes one of the major challenges in medicine. Though diet regulation and exercise are the primary treatment strategies, surgery is the most reliable long-term solution. Although bariatric surgical complications continue to decline, prompt recognition is essential to optimize patient outcomes. Despite their relative rarity, it is important to recognize thoracic complications, as several of these can result in severe morbidity and mortality. This article describes common bariatric surgical procedures performed, their expected postoperative appearances, and intrathoracic complications...

CASE DESCRIPTION A 3-year-old spayed female Bengal cat was evaluated because of a history of bilateral pleural effusion and hydronephrosis of the right kidney. CLINICAL FINDINGS Cytologic analysis of a pleural fluid sample revealed characteristics of a pure transudate with a high percentage of lymphocytes. Results of fluid biochemical testing were not consistent with urine or chyle. Serum biochemical analysis and echocardiography yielded no evidence of hypoalbuminemia or high hydrostatic pressure secondary to cardiac disease...

INTRODUCTION: In the last decade, video-assisted thoracoscopic surgery (VATS) lobectomy for non-small cell lung cancer (NSCLC) has had a major effect on thoracic surgery. Retrospective series have reported benefits of VATS when compared with open thoracotomy in terms of postoperative pain, postoperative complications and length of hospital stay. However, no large randomised control trial has been conducted to assess the reality of the potential benefits of VATS lobectomy or its medicoeconomic impact...

REVIEW
Maria Claudia Campos Mello Inglez de Souza, Ricardo José Rodriguez Ferreira, Geni Cristina Fonseca Patricio, Julia Maria Matera
Somatosensory evoked potentials (SSEPs) and motor evoked potentials (MEPs) are non-invasive neurophysiological tests that reflect the functional integrity of sensory and motor pathways. Despite their extensive use and description in human medicine, reports in veterinary medicine are scarce. SSEPs are obtained via peripheral stimulation of sensory or mixed nerves; stimulation induces spinal and cortical responses, which are recorded when sensory pathways integrity is preserved. MEPs can be obtained via transcranial electrical or magnetic stimulation; in this case, thoracic and pelvic limb muscle responses are captured if motor pathways are preserved...

Evaluation of the patient's medical history and a physical examination are the cornerstones of risk assessment prior to elective surgery and may help to optimize the patient's preoperative medical condition and to guide perioperative management. Whether the performance of additional technical tests (e.g. blood chemistry, ECG, spirometry, chest x-ray) can contribute to a reduction of perioperative risk is often not very well known or controversial. Similarly, there is considerable uncertainty among anaesthesiologists, internists and surgeons with respect to the perioperative management of the patient's long-term medication...

PURPOSE: Emergency department resuscitative thoracotomy is an intervention of last resort for the acutely dying victim of trauma. In light of improvements in pre-hospital emergency systems, improved operative strategies for survival such as damage control and improvements in critical care medicine, the most extreme of resuscitation efforts should be re-evaluated for the potential survivor, with success properly defined as the return of vital signs which allow transport of the patient to the operating room...

Donkeys are a member of the horse family (Equidae) and share a common ancestor. However, in morphological terms, donkeys and horses are regarded as two separate subgenus. Given variations in the branching pattern of the brachiocephalic trunk (BCT) in different species of animals and the use of donkeys in anatomy courses at colleges of veterinary medicine, we conducted this study in order to investigate the branching patterns of BCT and to describe detailed morphological information regarding donkeys. Seventeen mature donkeys were examined following euthanasia by exsanguination from the common carotid artery under general anaesthesia...

BACKGROUND: Double-lumen tracheal tube (DLT) insertion can be managed with videolaryngoscopes such as the Glidescope or indirect laryngoscopes like the Airtraq DL. No study has compared both devices when a difficult intubation is predicted. OBJECTIVE: Our hypothesis was that the Glidescope is superior to the Airtraq for double-lumen tube insertion in patients with a predicted or known difficult airway. DESIGN: Randomised study. PATIENTS: Adults scheduled for thoracic elective surgery, requiring one-lung ventilation with a predicted difficult intubation score of at least 7 (Arné risk index)...
