<em>Atelectasis, the partial or complete collapse of a lung or lobe, exhibits a challenge in a significant manner particularly in respiratory medicine Different factors are responsible for the occurrence of the development of atelectasis along with airway obstruction, compression of lung tissue and surfactant deficiency. Bronchodilators, namely anti cholinergic and beta _ agonists, play an important role regarding the management of atelectasis by relaxing the smooth muscles of air ways. These actions assists in alleviating broncho constriction as well as more air flow and facilitate lung re_ e

Abstract:
Most patients with thyroid carcinoma have a good prognosis. Due to the small number of fatal cases, it has not been clarified what conditions result in death for patients with thyroid carcinoma. To provide appropriate management for advanced thyroid carcinoma patients, we analyzed causes of death in 161 fatal cases. Clinical characteristics and immediate (final) causes of death based on pathological conditions were analyzed in 62 anaplastic carcinomas and 99 fatal differentiated carcinomas. Single fatal conditions could not be specified in 55 patients. In the remaining 106 patients, respirator

Abstract:
Adequate pulmonary function at birth depends upon a mature surfactant system and lungs of normal size. Surfactant is controlled primarily by hormonal factors, especially from the hypophysis, adrenal, and thyroid; but these have little influence on fetal lung growth. In contrast, current data indicate that lung growth is determined by the following physical factors that permit the lungs to express their inherent growth potential. (a) Adequate intrathoracic space: lesions that decrease intrathoracic space impede lung growth, apparently by physical compression. (b) Adequate amount of amniotic flu

Abstract:
Frequency-dependent characteristics of lung resistance (Rl) and elastance (El) are sensitive to different patterns of airway obstruction. We used an enhanced ventilator waveform (EVW) to measure inspiratory Rl and El spectra in ventilated patients during thoracic surgery. The EVW delivers an inspiratory flow waveform with enhanced spectral excitation from 0.156 to 8.1 Hz. Estimates of the coefficients in a trigonometric approximation of the EVW flow and transpulmonary pressure inspirations yielded inspiratory Rl and Elspectra. We applied the EVW in a group with mild obstruction undergoing vari

Decompression illness comprises decompression sickness resulting from tissue inert gas super-saturation and pulmonary barotraumas due to alveolar or airway over-distension. Gas bubbles can cause vascular obstruction or tissue compression, resulting in tissue ischaemia and oedema. Interactions between the blood–gas interface and the endothelium will result in further tissue damage, and trigger an inflammatory cascade with capillary leakage and haemoconcentration.

Abstract Airway stents are used to keep airways open for those patients symptomatic from tracheobronchial disease. Tracheobronchial disease or central airway obstruction (CAO) can occur with benign or malignant disease, or complications from lung transplantation. Although stents can offer symptomatic relief for CAO, complications such as granulation tissue formation, stent fracture, and infection commonly occur after stent placement. Currently, all airway stents promote mucus buildup which can lead to stent failure and airway complications. In this paper, we demonstrate the use of special anti

Asthma is a chronic inflammatory condition of the airways characterized by hyperresponsiveness and variable airflow obstruction. It often begins in childhood and can be triggered by several external factors such as allergens and pollutants. Inflammation involves mediators such as eosinophils, mast cells and cytokines, resulting in airway injury and tissue remodeling. During asthma attacks, bronchial obstruction occurs with lung hyperinflation and changes in ventilatory mechanics.
