In human-exhaled breath, more than 3000 volatile organic compounds (VOCs) are found which are directly or indirectly related to internal biochemical processes in the body. Electronic noses (E-noses) could play a potential role in screening/analyzing various respiratory and systemic diseases by studying breath signatures. E-nose integrates sensor array and an artificial neural network that responds to specific patterns of VOCs and thus can act as a non-invasive technology for disease monitoring. Gold standard blood glucose monitoring for diabetes diagnostics is invasive and highly uncomfortable...

Background: Lung cancer is a severe cancer with a high death rate. The 5-year survival rate for stage III lung cancer is much lower than stage I. Early detection and intervention of lung cancer patients can significantly increase their survival time. However, conventional lung cancer-screening methods, such as chest X-rays, sputum cytology, positron-emission tomography (PET), low-dose computed tomography (CT), magnetic resonance imaging, and gene-mutation, -methylation, and -expression biomarkers of lung tissue, are invasive, radiational, or expensive...

Screening studies on conventional chest X‑rays and on sputum cytology did not show a reduction in lung cancer mortality. However, screening by low-dose computed tomography (LDCT) is more promising because it allows tumor detection in early stages at fairly low radiation levels. No reduction of lung cancer mortality was found in two small, randomized clinical studies on LDCT screening in Europe. However, in the by far largest LDCT trial, the National Lung Screening Trial (NLST) in the USA, a relative reduction of lung cancer mortality by 20...

Lipoid pneumonia (LP) is an uncommon form of pneumonia that is characterized by the presence of intra-alveolar lipid and lipid-laden macrophages on microscopy. It categorized as exogenous lipoid pneumonia (ExLP) and endogenous lipoid pneumonia (EnLP). Exogenous lipoid pneumonia caused by inhalation of liposuction substances (animal fat, vegetable oil, or mineral oil), mostly, in adult cases, they were medicines for constipation or rhinopharyngitis. Most of these patients showed mild clinical manifestations, and chronic medical condition...

A 28-year-old woman who was 34 weeks pregnant was admitted with complaints of cough and blood-stained sputum. After delivery of the baby at 37 weeks gestation, computed tomography and magnetic resonance imaging revealed a tumor in the right lung and a 15-mm brain metastasis. A diagnosis of lung adenocarcinoma was made, cT4N3M1b (stage IV disease) by pleural fluid cytology. Additional testing for anaplastic lymphoma kinase (ALK) fusion protein showed a strongly positive result, which was then confirmed by fluorescence in situ hybridization...

Cancer is one of most fatal forms of disease with rapid, abnormal and uncontrolled division of cells which spreads into different organs in the body. The primary aim of this review is to showcase the current and emerging diagnostic techniques that are used in lung cancer detection. Lung cancer is a leading cause of death among smokers and it has been emerging in non-smokers due to passive smoke inhalation by non-smokers. The mortality rate of patients with lung cancer is very high due to the change in lifestyle and environmental factors...

Neutrophilic asthma (NA) is an important asthma inflammatory phenotype associated with disease severity, airflow limitation, and steroid resistance, and its mechanism is still uncertain. Evidences suggest a potential role for bacteria in its pathogenesis, but, so far, this remains poorly understood. We sought to investigate airway bacterial burden, community composition, and inflammatory response in NA. Fifty-four stable asthmatics without infection were enrolled and separated into either NA group (n = 20) or non-NA group (n = 34)...

BACKGROUND: Early detection decreases lung cancer mortality. The Target-FISH Lung Cancer Detection (LCD) Test is a non-invasive test designed to detect chromosomal changes (deletion or amplification) via Fluorescence in situ Hybridization (FISH) in sputum specimens from persons suspected of having lung cancer. We evaluated the performance of the LCD test in patients with highly suspicious pulmonary nodules who were scheduled for a biopsy procedure. METHODS: Induced sputum was collected from patients who were scheduled for biopsy of a solitary pulmonary nodule (0...

We present a case of 55-year-old man who complained of dyspnea and sputum for a month. He was an ex-smoker with a history of prostate cancer and pulmonary tuberculosis. Chest radiographs revealed bilateral pleural effusions of a small to moderate amount. Pigtail catheters were inserted for drainage. The pleural fluid consisted of large clusters and tightly cohesive groups of malignant cells, which however could not be ascribed to prostate cancer with certainty. We performed immunocytochemical panel studies to determine the origin of cancer metastasis...

Background: Methylated genes detected in sputum are promise biomarkers for lung cancer. Yet the current PCR technologies for quantification of DNA methylation and diagnostic value of the sputum biomarkers are not sufficient to be used for lung cancer early detection. The emerging droplet digital PCR (ddPCR) is a straightforward means for precise, direct, and absolute quantification of nucleic acids. Here, we investigate whether ddPCR can sensitively and robustly quantify DNA methylation in sputum for more precise diagnosis of lung cancer...
