Pulmonary function: increased residual volume, increased total lung capacity, fixed obstruction, low diffusing capacity of the lung for carbon monoxide that corrects with alveolar volume; High-resolution CT scan: diffuse pulmonary nodules 4–10 mm, greater than 20 nodules, mosaic attenuation or air trapping in greater than 50% of the lung
A lung nodule or pulmonary nodule is a relatively small focal density in the lung. A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules. One or more lung nodules can be ...
A study from a large referral center identified 19 cases (14 percent) from among 138 lung biopsy cases accrued over a 10-year period. Twenty-three NEH cases were included in a separate study testing chest CAT scan. The largest report to date includes 37 cases in a manuscript focusing on infant pulmonary function testing (PFT)
Caplan syndrome is a nodular condition of the lung occurring in dust-exposed persons with either a history of rheumatoid arthritis (RA) or who subsequently develop RA within the following 5–10 years. [3] The nodules in the lung typically occur bilaterally and peripherally, on a background of simple coal workers' pneumoconiosis. There are ...
A lung cyst, or pulmonary cyst, encloses a small volume of air, and has a wall thickness of up to 4 mm. [3] A minimum wall thickness of 1 mm has been suggested, [3] but thin-walled pockets may be included in the definition as well. [4] Pulmonary cysts are not associated with either smoking or emphysema. [5]
ADHD can only be diagnosed by a licensed clinician, and the first step to do so is via screening with validated tools to screen for ADHD in adults. [10] [12] [13] The Adult ADHD Self Report Rating Scale (ASRS) is a validated screening tool recognized by the World Health Organization (WHO) with a sensitivity and specificity of 91.4% and 96.0% ...
A journal report from 1983 indicated that untreated DPB had a five-year survival rate of 62.1%, while the 10-year survival rate was 33.2%. [6] With erythromycin treatment, individuals with DPB now have a much longer life expectancy due to better management of symptoms, delay of progression, and prevention of associated infections like P ...
Atypical adenomatous hyperplasia is a subtype of pneumocytic hyperplasia in the lung. It can be a precursor lesion of in situ adenocarcinoma of the lung (bronchioloalveolar carcinoma). In prostate tissue biopsy, it can be confused for adenocarcinoma of the prostate. The needle biopsy rate is less than 1%.
