A 33-year-old immunocompetent man was admitted to the authors' hospital with a one-month duration of fevers, chills, and non-productive coughs, and suddenonset weakness and ischemic pain of both lower extremities. Physical examination revealed crepitating rales heard over bilateral lung fields. On auscultation, a grade 2~3/6 systolic murmur was heard over the leftlower sternal border and apical area. Transthoracic echocardiography revealed a mobile mass on the tricuspid valve compatible with vegetation, in addition to concomitant mitral valve vegetation (Video 1)...

We present the case of an adult patient with active post-primary pulmonary tuberculosis (TB) and discuss specific morphological and textural aspects found at high-field magnetic resonance imaging (MRI) of the lung. The 42-year-old man, heavy smoker, undertook a routine employment medical examination and was admitted to a referral pulmonology and TB center due to the abnormal findings seen on his chest radiography. The patient presented nonspecific symptoms, bilateral bronchial breath at pulmonary auscultation, inflammatory syndrome on the laboratory blood tests and positive sputum smears for acid-fast bacilli, which together with the typical aspect on the chest radiography lead to a diagnosis of post-primary pulmonary TB and administration of specific medication...

INTRODUCTION: Interstitial lung disease (ILD) is currently the primary cause of death in systemic sclerosis (SSc). Thoracic high-resolution computed tomography (HRCT) is considered the gold standard for diagnosis. Recent studies have proposed several clinical algorithms to predict the diagnosis and prognosis of SSc-ILD. OBJECTIVE: To test the clinical algorithms to predict the presence and prognosis of SSc-ILD and to evaluate the association of extent of ILD with mortality in a cohort of SSc patients...

BACKGROUND: The basic requirements for monitoring anesthetized patients during surgery are assessing cardiac and respiratory function. Esophageal stethoscopes have been developed for this purpose, but these devices may not provide clear heart and lung sound due to existence of various noises in operating rooms. In addition, the stethoscope is not applicable for continues monitoring, and it is unsuitable for observing inaccessible patients in some conditions such as during CT scan. OBJECTIVE: A wireless electronic esophageal stethoscope is designed for continues auscultation of heart and lung sounds in anesthetized patients...

INTRODUCTION: A 71 year old Peruvian woman presented with blurry vision and bilateral eye pain and had evidence of bilateral endophthalmitis on eye examination. Her past medical history was notable for multiple abdominal surgeries within the preceding months, including an incarcerated inguinal hernia repair which required an ileostomy placement, and cholecystitis requiring cholecystostomy tube placement. Over her multiple long hospitalizations, she developed bacteremia and fungemia on several occasions, with organisms including Enterobacter cloacae, Klebsiella pneumoniae, Bacteroides fragilis, Pseudomonas aeruginosa, Enterococcus faecium, and Candida albicans...

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...

Diffuse panbronchiolitis (DPB) and asthma are obstructive airway diseases, the former being characterized by Th1-type and the latter by Th2-type airway inflammation. Differential diagnosis is often a problem, but coexistence has rarely been reported. A 76-year-old man with asthma was admitted to our hospital because of one-month history of dyspnoea on exertion with bilateral diffuse granular shadows. He also had a history of chronic sinusitis. Auscultation of the lungs showed coarse crackles and wheezes. Laboratory data revealed an elevated total serum immunoglobulin E and a high titre of cold agglutinin...

RATIONALE, AIMS, AND OBJECTIVES: Community-acquired pneumonia (CAP) is a common cause for intensive care unit (ICU) admission resulting in high morbidity and mortality. There is a paucity of evidence regarding respiratory physiotherapy for intubated and mechanically ventilated patients with CAP, and anecdotally clinical practice is variable in this cohort. The aims of this study were to identify the degree of variability in physiotherapy practice for intubated adult patients with CAP and to explore ICU physiotherapist perceptions of current practice for this cohort and factors that influence physiotherapy treatment mode, duration, and frequency...

Background: The early diagnosis of idiopathic pulmonary fibrosis (IPF) has become increasingly important due to evolving treatment options. IPF patients experience a significant delay in receiving an accurate diagnosis, thus delayed access to tertiary care is associated with higher mortality independently from disease severity. Objective: The aims were to evaluate whether there had been a delay in the referral process, and to determine whether the referring doctors had suspected IPF or other interstitial lung disease (ILD) already during the time of referral...

The analysis of lung sounds, collected through auscultation, is a fundamental component of pulmonary disease diagnostics for primary care and general patient monitoring for telemedicine. Despite advances in computation and algorithms, the goal of automated lung sound identification and classification has remained elusive. Over the past 40 years, published work in this field has demonstrated only limited success in identifying lung sounds, with most published studies using only a small numbers of patients (typically N<;20) and usually limited to a single type of lung sound...

Asthma is the most common chronic illness among children. The skills required to diagnose it make it an even greater concern. In this work, we present a child-friendly wearable device, which allows in-home diagnosis of asthma. The device acquires simultaneous measurements from multiple stethoscopes. The recordings are then sent to a specialist who uses assistive diagnosis algorithms that enable auscultation (listening to lung sounds with a stethoscope) at any location in the lungs volume by sound refocusing...

Excessive lung water occurs when too much water accumulates in the lung, causing breathing difficulty. Current diagnosis methods include X-rays and CT-scans. However, because of their bulk and the need for trained professionals to operate, physicians rely on auscultation for preliminary diagnosis. Recent attempts have been made to automate the auscultation process and some degree of success has been reported. Thus, it would be useful to provide more analysis of such lung sounds. This paper attempts to study the characteristics of breathing sounds from lungs with excessive water and compare them with breathing sounds from healthy lungs...

We propose an improved approach for distinguishing between healthy subjects and patients with pulmonary emphysema by the use of one stochastic acoustic model for continuous adventitious sounds and another for discontinuous adventitious sounds. These models are able to represent the spectral features of the adventitious sounds for the detection of abnormal respiration. However, abnormal respiratory sounds with unclassifiable spectral features are present among the continuous and discontinuous adventitious sounds and mixing noises...

PURPOSE: The role of (18)F-fluorodeoxyglucose positron emission tomography-computed tomography ((18)F-FDG PET/CT) in the diagnosis of metastatic infectious foci in children with catheter-related blood stream infection has been hardly studied, although some authors have reported it benefit in the screening of metastatic foci in adult population. Septic pulmonary emboli are among the most difficult to identify, because many cases do not present pulmonary complaints or abnormal chest radiography...

Human metapneumovirus (hMPV), formerly classified in Paramyxoviridae family is now moved into Pneumoviridae, which was described as a novel family. It causes upper and lower respiratory tract infections (LRTIs) usually in children younger than five years old. The recent epidemiological studies indicated that hMPV is the second most frequently detected virus in LRTIs of young children, following the respiratory syncytial virus (RSV). Bronchiolitis obliterans (BO) is a chronic obstructive lung disease characterized by fibrosis of the distal respiratory airways...
