This article describes the case history of a 59-year-old female patient who sought advice for temporomandibular joint (TMJ) pain and sounds but who was actually diagnosed with a primary lung cancer with metastasis to the TMJ. The patient had a history of TMJ pain and deflection in jaw movement that progressively worsened over a few months and did not improve with the usual standard of care treatment provided by an orofacial pain practitioner. Magnetic resonance and computed tomography (CT) prescribed at a tertiary clinic showed an osteolytic bone mass within the right TMJ condyle...

C Bowe, F Jenssen, A Espinoza
INTRODUCTION: The prevalence of sarcoidosis varies as much as 1-40 cases per 100,000 depending on region and population. Sarcoid typically occurs in people younger than 50 years old, with a peak incidence with ages between 20 and 40 years old. African Americans are 3 times more likely to develop sarcoidosis than Caucasian Americans, and woman are more likely than men to develop sarcoidosis in any ethnic group; nonetheless, it remains a valid differential across any population. CASE: A 32 year old Hispanic man presented to the Emergency Department with night sweats, fatigue, and 35 pound unintentional weight loss over the last several weeks...

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...

Approximately two decades ago, thoracic surgery witnessed the leap from thoracotomy to the first video-assisted thoracic surgery (VATS) lobectomy. Minimally invasive lobectomy and hilar lymphadenectomy is now widely established as a safe and oncological sound technique that is the standard of care for early-stage lung cancer. The move toward less invasive surgery has no doubt driven the innovation of sophisticated instruments and technology to cope with the demanding need of working through a restricted incision...

OBJECTIVES: To conduct histopathological studies on various organs in three different groups of female rats for adverse effects of pulsed magnetic stimulation (MS). Blood tests and body and organ weights were also studied. METHODS: A high-frequency continuous magnetic stimulator was used (SMN-X, Nihon Kohden, Tokyo). Thirty-four female Sprague-Dawley rats (SPF) were randomly divided into three groups: treatment (MS) groups with 12 and 36 stimulations (seven rats in each); sham groups exposed only to sounds of stimulation for 12 and 36 times; (seven rats in each); and control groups with no stimulation or sound during the same periods of 12 and 36 stimulations (five rats in each)...

PURPOSE: Airway inflammation can be detected by lung sound analysis (LSA) at a single point in the posterior lower lung field. We performed LSA at 7 points to examine whether the technique could identify the location of airway inflammation in patients with asthma. PATIENTS AND METHODS: Breath sounds were recorded at 7 points on the body surface of 22 asthmatic subjects. Inspiration sound pressure level (ISPL), expiration sound pressure level (ESPL), and the expiration-to-inspiration sound pressure ratio (E/I) were calculated in 6 frequency bands...

INTRODUCTION: Brain metastases in EGFR/ALK-driven NSCLC frequently pose treatment dilemmas. Tyrosine kinase inhibitors (TKIs) can control extracranial disease, but radiotherapy is often required for intracranial control. We aimed to evaluate the impact of first-line whole brain radiotherapy (WBRT), stereotactic radiotherapy (SRS) or TKI alone on outcomes of patients with brain metastases from EGFR/ALK-driven NSCLC. METHODS: This single center retrospective review included 184 patients with brain metastases from EGFR/ALK-driven NSCLC, and analyzed effect of treatment choice on time to intracranial progression (TTIP) and overall survival (OS)...

The respiratory system dynamic is of high significance when it comes to the detection of lung abnormalities, which highlights the importance of presenting a reliable model for it. In this paper, we introduce a novel dynamic modelling method for the characterization of the lung sounds (LS), based on the attractor recurrent neural network (ARNN). The ARNN structure allows the development of an effective LS model. Additionally, it has the capability to reproduce the distinctive features of the lung sounds using its formed attractors...

Macrophage activation syndrome (MAS) is one of the serious complications associated with rheumatic diseases, especially systemic juvenile idiopathic arthritis (sJIA). Here we describe a 9-year-old girl with rheumatoid factor (RF)-positive polyarticular JIA, not sJIA, combined with pneumonia who was successfully treated by plasma exchange. She was diagnosed with RF-positive polyarticular JIA based on positive RF and multiple joint swelling and tenderness 3 years ago. She was admitted in our hospital with myalgia for 2 days and a high fever for half a day...

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...

We examined preserved medical charts of 470 Spanish influenza patients (8 with fatal cases) hospitalized at former army hospitals in Japan during 1919-1920. The following factors were associated with longer periods of hospitalization: adventitious discontinuous lung sounds, maximum respiration rate, continuation of high fever after hospital admission, and diphasic fever.

BACKGROUND: We previously reported the results of lung sound analysis in patients with bronchial asthma and demonstrated that the exhalation-to-inhalation sound pressure ratio in the low frequency range between 100 and 200 Hz (E/I LF) was correlated with the presence of airway inflammation and airway obstruction. We classified asthma patients by airway inflammation phenotype using the induced sputum eosinophil and neutrophil ratio and determined whether this phenotype could be predicted using E/I LF and fractional exhaled nitric oxide values...

AIM: To investigate in human dental pulp fibroblasts (HDPF) the expression of factors involved in dental pulp physiopathological processes and in an experimental model of cell activation called nemosis, and to compare the behaviour of pulp cell activation with sound lung fibroblast MRC5, employed as a reference model for nemosis. METHODOLOGY: Nemotic response was induced in three-dimensional cultures of HDPF and lung fibroblasts. The expressions of molecules involved in physiological (alkaline phosphatase, type I collagen) and in inflammatory processes (IL-6, CXCL8, CCL20, COX-2) were studied using real-time PCR...

Lung sound signal processing has proven to be a great improvement to the traditional acoustic interpretation of lung sounds. However, that analysis can be seriously hindered by the presence of different types of noise originated in the acquisition environment or caused by physiological processes. Consequently, the diagnostic accuracy of pulmonary diseases can be severely affected, especially if the implementation of telemonitoring systems is considered. The present study is focused on the implementation of an algorithm able to identify noisy periods, either voluntarily (vocalizations, chest movement and background voices) or involuntarily produced during acquisitions of lung sounds...

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...

In this work, a wavelet based classification system that aims to discriminate crackle, normal and wheeze lung sounds is presented. While the previous works related with this problem use constant low Q-factor wavelets, which have limited frequency resolution and can not cope with oscillatory signals, in the proposed system, the Rational Dilation Wavelet Transform, whose Q-factors can be tuned, is employed. Proposed system yields an accuracy of 95 % for crackle, 97 % for wheeze, 93.50 % for normal and 95.17 % for total sound signal types using energy feature subset and proposed approach is superior to conventional low Q-factor wavelet analysis...
