Background Sclerotherapy has been gaining increased acceptance and popularity as an effective therapy for the treatment of varicose veins. This attention has fed growing interest into the safety and potential complications of this procedure. There is no evidence of pulmonary complications from foam sclerotherapy in humans; however, animal studies have shown possible damage. The aim of this study is to show the changes in rat pulmonary parenchyma after the injection of 1% polidocanol Tessari foam into the peripheral vein using histological analysis of the inflammatory and fibrosis processes...

Pheochromocytoma multisystem crisis is a rare and life-threatening disease that is associated with numerous symptoms and which is also difficult to diagnose. We herein report an autopsy case of a 61-year-old man who died due to pheochromocytoma multisystem crisis. The patient complained of vomiting and breathlessness. Computed tomography showed a shadow-like region with a similar appearance to interstitial pneumonia. The patient was diagnosed with takotsubo cardiomyopathy induced by severe lung disease based on the results of echocardiography and coronary angiography...

Occupational exposure is an important, global cause of respiratory disease. Unlike many other non-communicable lung diseases, the proximal causes of many occupational lung diseases are well understood and they should be amenable to control with use of established and effective approaches. Therefore, the risks arising from exposure to silica and asbestos are well known, as are the means of their prevention. Although the incidence of occupational lung disease has decreased in many countries, in parts of the world undergoing rapid economic transition and population growth-often with large informal and unregulated workforces-occupational exposures continue to impose a heavy burden of disease...

BACKGROUND: The use of pulmonary function tests is primarily based on expert opinion and international guidelines. Current interpretation strategies are using predefined cutoffs for the description of a typical pattern. OBJECTIVES: We aimed to explore the predicted disease outcome based on the American Thoracic Society/European Respiratory Society (ATS/ERS) interpreting strategy. Subsequently, we investigated whether an unbiased machine learning framework integrating lung function with clinical variables may provide alternative decision trees resulting in a more accurate diagnosis...

DLNO/DLCO directly measures the ratio of the diffusing capacities of the lung for nitric oxide (NO) and carbon monoxide (CO). In terms of the Roughton and Forster, 1957; equation, 1/DL=1/Dm+1/θVc, where Dm is the membrane (Dm) and θVc is the red cell component of the overall diffusing conductance (DL), DLNO mostly reflects the Dm component and DLCO the θVc red cell component. The DLNO/DLCO ratio is positively related to the DmCO/Vc ratio and the CO red cell resistance (1/θCOVc) as a percentage of the total resistance (1/DLCO), independent of the absolute values of DLNO or DLCO...

BACKGROUND/AIM: Determining the severity of systemic sclerosis related interstitial lung disease (SSc-ILD) is based on clinical and radiological findings, inflammation marker levels, and carbon monoxide diffusing capacity of the lung (DLCO). Recently studies are ongoing for objective and easy markers. Neutrophil/lymphocyte ratio (NLR) is shown to be a good marker for inflammation in recent clinical trials. In this study, we aimed to identify the possible relationship between NLR and carbon monoxide transfer coefficient (KCO) of SSc-ILD patients...

The concept of end-stage lung disease suggests a final common pathway for most diffuse parenchymal lung diseases. In accordance with this concept, end-stage disease is characterized radiographically and pathologically by the presence of extensive honeycombing. However, sequential computed tomographic (CT) scans obtained from patients with chronic diffuse lung disease evolve over time to show various advanced lung disease patterns other than honeycombing. Also, several radiographically distinct honeycomb patterns, including microcystic, macrocystic, mixed, and combined emphysema and honeycombing differentiate one advanced lung disease from another...
