Respiratory physiology is influenced by cognitive processes. It has been suggested that some cognitive states may be inferred from respiration amplitude responses (RAR) after external events. Here, we investigate whether RAR allow assessment of fear memory in cued fear conditioning, an experimental model of aversive learning. To this end, we built on a previously developed psychophysiological model (PsPM) of RAR, which regards interpolated RAR time series as the output of a linear time invariant system. We first establish that average RAR after CS+ and CS- are different...

INTRODUCTION: Traumatic diaphragmatic injuries (TDIs) are clinically challenging. We aimed to review TDIs treated at a tertiary trauma centre over a 12-year period. METHODS: This was a single-centre retrospective review of adult patients with TDIs treated between 1 January 2003 and 31 December 2014. Primary outcomes were mortality rates and Injury Severity Scores (ISS) associated with each TDI subtype. Secondary outcomes included proportions of TDIs diagnosed radiologically, operatively or during autopsy...

BACKGROUND: The London Chest Activities of Daily Living Scale measures the impact of breathlessness on both activity and social functioning. However, the London Chest Activities of Daily Living Scale is not routinely used in patients with advanced disease. AIM: To assess the psychometric properties of the London Chest Activities of Daily Living Scale in patients with refractory breathlessness due to advanced disease. DESIGN: A cross-sectional secondary analysis of data from a randomised controlled parallel-group, pragmatic, single-blind fast-track trial (randomised controlled trial) investigating the effectiveness of an integrated palliative and respiratory care service for patients with advanced disease and refractory breathlessness, known as the Breathlessness Support Service (NCT01165034)...

A man aged 28 years, with neurofibromatosis type 1, presented with abdominal pain and visible right lower chest swelling. He had cutaneous neurofibromas and several café-au-lait spots. CT scan of the chest and abdomen revealed a giant mass most likely originating from the right 7th intercostal nerve, extending downwards into the abdomen causing massive hepatic compression. A Trucut biopsy showed malignant peripheral nerve sheath tumour. Radical surgical resection with wide margins was performed. The chest wall and diaphragm were reconstructed with improvised surgical technique with excellent results...

BACKGROUND: Guidelines for diagnosing acute myocardial infarction (AMI) recommend adding kinetic changes to the initial cardiac troponin (cTn) blood concentration to improve AMI diagnosis. We hypothesized that kinetic changes may not be required in patients presenting with highly abnormal cTn. METHODS: Patients presenting with suspected AMI to the emergency department were enrolled in a prospective diagnostic study. We assessed the positive predictive value (PPV) of initial high-sensitivity cardiac troponin T (hs-cTnT) blood concentrations alone and in combination with kinetic changes for AMI...

A 16-year-old white man was involved in a motor vehicle collision and suffered head, chest, and abdominal trauma. Despite initial resuscitative efforts, he progressed to brain death and was designated to be an organ donor by his family. He had no earlier medical or surgical history and no high-risk behaviors. Blood work revealed normal creatinine, liver function tests, lipase, and amylase. Viral serologies were negative except for cytomegalovirus IgG and Epstein-Barr virus nucleic acid. Imaging revealed a right kidney contusion, a manubrial fracture, and fractures of right first rib and bilateral scapulae...

INTRODUCTION: Takotsubo cardiomyopathy (TCM), also known as "broken heart syndrome," "apical ballooning syndrome," and "stress-induced cardiomyopathy," was first described in Japanese patients in 1990 by Sato et al. TCM is an increasingly recognized syndrome characterized by transient and reversible systolic dysfunction of the apical and middle segments of the left ventricle. This syndrome resembles acute myocardial infarction in the absence of evident coronary artery occlusion. Herein, we present a case of a 51-year-old male who underwent his second deceased-donor renal transplantation for end-stage-renal-disease due to a work-related accident...

Early rule-in and rule-out of non-ST-segment elevation myocardial infarction (NSTEMI) is a challenge. In patients with inconclusive findings on ECG, cardiac biomarkers play a crucial role in the diagnosis. The introduction of the new high-sensitive cardiac troponin test (hs-TnI assay) has changed the landscape of NSTEMI diagnosis. The new hs-TnI assay can detect troponin values at a lower level compared with a contemporary cardiac troponin (cTn) assay. The hs-cTnI assay has a coefficient of variation of ≤10%, well below the 99th percentile value...

The ingestion of cell batteries can cause serious complications (fistula, perforation or stenosis) at the esophageal level. The damage starts soon after ingestion (approximately 2 hours) and is directly related to the amount of time the battery is lodged in said location, the amount of electrical charge remaining in the battery, and the size of the battery itself. Injury is produced by the combination of electrochemical and chemical mechanisms and pressure necrosis. The ingestion of multiple cells and a size > = 20 mm are related with more severe and clinically significant outcomes...

BACKGROUND: The pathophysiology of acute pericarditis remains largely unknown and biomarkers are needed to identify patients susceptible to complications. Since adipose tissue has a pivotal role in cardiovascular disease pathogenesis, we hypothesized that quantification of epicardial fat volume (EFV) provides prognostic information in patients with acute pericarditis. MATERIALS AND METHODS: Fifty (n=50) patients with first diagnosis of acute pericarditis were enrolled in this study...

During the last 1.5 years an update of the guideline on silicosis was made by an interdisciplinary working group. New medical and scientific knowledge and the experience in expert opinion practice were taken into account.By preparing the initial guideline in 2010 standardization of diagnostics and adaption of the "Moers convention" which was not based on medical knowledge was in the focus, whereas the current update deals with fine emendation and extension, especially of the compensation rate (adaption with the Reichenhall recommendation)...

Pregnant women should be tested with immune tests for tuberculosis when they undergo TB screening according to the German Infectious Diseases Protection Act. Interferon Gamma Release Assays (IGRAs) should be the priority tests used for pregnant refugees and asylum seekers, especially when migrating from high incidence countries (> 20 cases/100.000 population according to the ECDC) or when they fled from crisis regions; positive tuberculin skin tests should be veryfied with IGRA. Once immunological tests are suggesting a latent tuberculosis infection it should be considered that pregnant women have an increased risk of developing active tuberculosis with potential health threats for the unborn child...

BACKGROUND/AIMS: Previous studies demonstrated an alteration of diaphragmatic excursion on the paretic side after stroke; however, it is unclear if this change has clinical repercussions. We aimed to determine if there was an association between the paretic side and the laterality of pneumonia after stroke. METHODS: A retrospective analysis of a consecutive cohort of patients admitted to a stroke unit from 2008 to May 2016 was performed. Patients with the diagnosis of acute stroke and pneumonia were included...

INTRODUCTION: Endoscopic sinus surgery is a minimally invasive procedure used to restore normal sinus ventilation and mucociliary function. It is a routine otolaryngology procedure with a success rate of about 90% for symptomatic improvement in patients with refractory chronic rhinosinusitis. Because of the proximity of the paranasal sinuses to the brain and the orbit, it cannot be performed without a potential risk of complications. In our case, without early clinical suspicion, proper diagnosis and management, this unusual occurrence of pneumomediastinum after endoscopic sinus surgery may have led to major complications or even death...

In Nigeria, a large number of radiographic examinations are conducted yearly for various diagnostic purposes. However, most examinations carried out do not have records of doses received by the patients, and the employed exposure parameters used are not documented; therefore, adequate radiation dose management is hin-dered. The aim of the present study was to estimate the dose-area product (DAP) of patients examined in Nigeria, and to propose regional reference dose levels for nine common examinations (chest PA, abdomen AP, pelvis AP, lumbar AP, skull AP, leg AP, knee AP, hand AP, and thigh AP) undertaken in Nigeria...

Brass mesh bolus has been shown to be an acceptable substitute for tissue-equivalent bolus to increase superficial dose for chest wall tangent photon radiotherapy. This work investigated the increase in surface dose, the change in the dose at depth, and the safety implications of higher energy photon beams when using brass mesh bolus for postmastectomy chest wall radiotherapy. A photon tangent plan was delivered to a thorax phantom, and the superficial dose ranged from 40%-72% of prescription dose with no bolus...

Community-acquired pneumonia is a leading cause of death. Risk factors include older age and medical comorbidities. Diagnosis is suggested by a history of cough, dyspnea, pleuritic pain, or acute functional or cognitive decline, with abnormal vital signs (e.g., fever, tachycardia) and lung examination findings. Diagnosis should be confirmed by chest radiography or ultrasonography. Validated prediction scores for pneumonia severity can guide the decision between outpatient and inpatient therapy. Using procalcitonin as a biomarker for severe infection may further assist with risk stratification...
