The relation between insulin resistance and lung function: a cross sectional study.

Background: Impaired lung function and insulin resistance have been associated and thereby have also been indicated to be powerful predictors of cardiovascular mortality. Therefore, the co-existence of insulin resistance and impaired lung function accompanied with cardiovascular risk factors should induce cardiovascular mortality even in patients without known respiratory disease in a cumulative pattern. It could be useful to determine the lung function of patients with insulin resistance in order to decrease cardiovascular mortality by means of taking measures that minimize the risk of decline in lung function.

Pulmonary fibrosis developed secondary to methotrexate use in a patient with psoriasis vulgaris.

Methotrexate is the folic acid analogue drug that used in various dermatological disorders, especially in psoriasis. Cutaneous and systemic side effects can be seen during methotrexate treatment. A 58-year-old female patient presented with persistent cough last one month.

Does Helicobacter pylori infection play a role in lung cancer?

Background: Helicobacter pylori infection is a world-wide common disease and leads to many gastrointestinal and respiratory illnesses. It is suggested that one of these respiratory illnesses is lung cancer.

Methods: Forty-three patients with non-small cell lung cancer and 28 control subjects have been included to this study.
