The debates and controversies regarding the control and treatment of intraepitelial bronchial ...

Due to advances in interventional bronchoscopy, curative treatment has become possible for central type lung cancer if it is detected in the early stage. However, expertise is required to diagnose the intraepithelial lesions by conventional white light bronchoscopy alone, but judgement is still subjective. The combination of white light and autofluorescence bronchoscopy has ...

Persistent hydropneumothorax was diagnosed in a 62-year-old female with a history of blunt trauma, although she was treated with chest tube and closed underwater seal drainage. Computed tomography and fiberoptic bronchoscopy findings were consistent with "fallen lung" syndrome. Fiberoptic bronchoscopy also found a cavitary lesion at the right tracheobronchial angle. Forceps ...

Bronchiectasis is an airway disease caused by the dilatation of the bronchial tree, and a bronchovascular pair is formed between a bronchus and a vessel. An abnormal bronchovascular pair is one that has a larger bronchus compared to its accompanying vessel. Typically, bronchi and vessels running perpendicular to the plane of section appear as near-circular ...

Five types have been classified ...

During a recent investigation of LKB1 gene abnormality in lung lesions, strong expression of LKB1 protein in normal neuroendocrine (NE) cells of the bronchial epithelium was found. Because LKB1 functions as a tumor suppressor gene, the question of whether alteration of LKB1 expression is related to the development of pulmonary NE ...

The changes fall into four principal groups: abnormal soft ...

Bronchoscopy with an yttrium-aluminium-garnet (YAG) laser is often used to resect benign and malignant airway tumors and for relief of associated airway stenosis. Complications of this procedure include airway obstruction and hemorrhage. Partial extracorporeal circulation for YAG laser resection in the airway may be helpful in minimizing these complications. Extracorporeal lung assist (ECLA) ...

ABSTRACT BACKGROUND: Common Variable Immunodeficiency patients suffer from respiratory infections leading over time to permanent lung damage. Increased radio sensitivity has been described and clinicians should consider a risk-benefit assessment when ordering a Computed Tomography in that the exact level of 'safe' radiation exposure is unknown. METHODS: 21 patients with CVID were evaluated with ...

Bronchial asthma is a clinical syndrome characterized by the reversibility of airway obstruction. Recently it has been suggested that remodeling of the airway causes irreversible airway obstruction which may be responsible for the patient's symptoms. With this background, the purpose of the present study was to assess patients with corticosteroid-dependent asthma by Tc-99m ...

Tuberculosis pathology was studied on 19 African buffalo (Syncerus caffer) from a herd in the Hluhluwe-iMfolozi Park in South Africa. The animals tested positive with the comparative intradermal tuberculin test and were euthanized during a test-and-cull operation to decrease prevalence of bovine tuberculosis (bTB) in the park. The lymph nodes and lungs were examined grossly for presence of ...

Intermittent episodes of fever, severe dyspnoea and cyanosis were observed in a two-and-a-half-year-old male German shepherd dog. The clinical signs were of sudden onset but disappeared within eight hours, in five almost identical episodes over a period of 40 days. Radiological examination of the thorax revealed a large rounded area of radiolucency surrounded by a thin radiopaque structure. The ...

The 49 cases received irradiation of the thorax for breast cancer, ...

Several organs (lung, skin, thyroid, heart, bone marrow) are potential targets of cobalt (Co). Whereas there is no doubt that inhalation of Co alone may cause bronchial asthma, its role in the occurrence of hard metal disease is still controversial because most cases were reported in workers exposed not only to Co but also to other substances such as tungsten carbide, titanium ...

Of the more than 50 million Pap smears performed annually in the United States, about 5% of them are abnormal. Although the need for treatment of high-grade lesions is clear, the appropriate management of low-grade lesions remains controversial. New methods of screening for cervical cancer have become available, including testing for ...

Diabetic retinopathy is a serious long-term complication of diabetes mellitus. There is considerable interest in using mouse models, which can be genetically modified, to understand how retinopathy develops and can be inhibited. Not all retinal lesions that develop in diabetic patients have been reproduced in diabetic mice; conversely, not all ...
