Study of methacholine positivity in patients with chronic cough at Masih Daneshvari hospital, Tehran, 2007-2008.

While airways reactivity is among the characteristics of asthma, it is not considered a sufficient condition diagnostically and the methacholine challenge is a non-specific diagnostic aid in cases of chronic cough and reactive airways disease. The aim of this cross-sectional study was to determine the metacholine response positivity and diagnosis of asthma in patients with chronic cough presenting to a hospital in Tehran during 2007 and 2008. Of 101 patients with chronic cough (with no history of sinusitis, recent pulmonary infection, bronchitis, gasteroesophageal reflux or underlying pulmonary conditions), 51.5% showed reactive airways disease to the methacholine test, 40.6% were unreactive and 7.9% were indeterminate. A positive methacholine challenge test was positively correlated with new wheezing. Although the methacholine challenge test is not a primary test for evaluating chronic cough, if no other reason for chronic cough is found, it may be a guiding test for asthma.

Cases non-specific interstitial pneumonia and hypersensitivity pneumonia: A new pathologic diagnosis or overlap syndrome.

ATS/ERS evaluation of ILD's has recently considered NSIP as a single entity and it has historically been considered a provisional diagnosis. As more cases are reviewed, pathologic characteristics may become more precise with less overlap and help in diagnosis of complex cases. Here, we present a series of cases of HP and NSIP recently admitted to Masih Daneshvari Hospital with hope to characterize them better and eventually have less ambiguity about nature of NSIP.

Study of depressed mood and quality of life in asthma patients in Tehran using the 28-item general health questionnaire.

The prevalence of depression among the general population has been estimated as up to 50% and even higher among asthmatics. The aim of this cross-sectional study was to evaluate the prevalence of depressed mood among asthma patients (n = 280) attending a pulmonary clinic in Tehran and compare it with measures of severity of asthma and of health and well-being. The prevalence of depression symptoms on the 28-item general health questionnaire (GHQ-28) was 65.4%. Patients' individual scores on the GHQ-28 were significantly correlated with the number of asthma medications used, frequency of visits to the pulmonary clinic and frequency of hospitalizations for asthma, but not with FEV1. A significant correlation was found between patients' total scores on the GHQ-28 and total and subscale scores on the Saint George respiratory questionnaire. The GHQ-28 may be useful for screening for asthma patients who need more attention and therapeutic intervention for psychiatric disorders.
