A 59-year-old male smoker presented with persistent wheezing and occasional coughing that had been ongoing for two years and had been unsuccessfully treated with an inhalational β2 agonist, an anticholinergic and an inhalational steroid in the last year. On clinical examination, a left-sided wheeze was detected. The initial chest X-ray was normal. A computed tomography (CT) scan of thorax demonstrated a mass lesion in the left main bronchus. On subsequent bronchoscopy, an endobronchial polypoid mass was detected in the left main bronchus, completely occluding the bronchial lumen. A biopsy taken from the mass revealed features of bronchial carcinoid. Bronchial carcinoid can present uncommonly with wheezes, resulting in misdiagnosis as bronchial asthma or chronic obstructive pulmonary disease (COPD). If an asthma or COPD patient does not respond to conventional therapy, a CT scan and subsequent bronchoscopy is warranted.

It is nonlinear relationship between breath sounds and respiratory flow rate, thus breath sounds might be a new solution for respiratory monitoring. The envelope of the breath sounds was created firstly. And the linear relationship between the logarithm of envelope and the respiratory flow rate was proved. Then model parameters were derived from every subject using regression analysis. Finally, using these parameters estimated respiratory flow rate was achieved by the logarithm of envelope with 14.9% error. Therefore, respiratory flow rate estimation and respiration monitoring based on breath sounds are feasible.

Malignant Mixed Mullerian tumors(MMMTs) are unusual neoplasms occumng mostly in the uterus and, ralely, they arise in the ovary. The clinical features of malignant mixed mullerian tumor of the ovary are similiar to other ovarian malignancies. The clinical course is rapidly progressive and fatal. The optimal treatment modalities has remained elusive. The most reliable prognostic criterion is the initial tumor stage and the overall survival was poor. We experienced two cases of malignant mixed miillerian tumor of the ovary, so we report these cases with a brief review of the concerned literatures.

Bronchial asthma is a chronic inflammatory disease of the airways in which there isincreased responsiveness to various stimuli, resulting in wheezing, shortness of breath, and coughing. Interactions between environmental and genetic factors may modify both the susceptibility to and severity of the disease. In recent years, much progress has been made in improving our understanding of the genetic basis of bronchial asthma, which has led to the identification of several genetic factors. This review is an update of genetic studies of bronchial asthma and recent findings.
