[Application of interventional respiratory techniques in the treatment of pulmonary bullae:an update].

Pulmonary bullae is a common complication of chronic obstructive pulmonary disease(COPD), causing the deterioration in lung function, leading to aggravated dyspnea and poor quality of life for patients. The traditional therapeutic approach for pulmonary bullae is bullectomy using surgical thoracoscopy. The disadvantage of this approach is the postoperative complications and high risk of recurrence in many patients. In addition, for some patients, due to the patient's physical conditions, such as poor lung function and other diseases, bullectomy could not be used. Therefore, new alternative approaches were urgently needed. In recent years, interventional respiratory technology has been trialed to treat pulmonary bulla all around the world and has achieved great success. In this paper, we reviewed the relevant clinical research progress of interventional respiratory medicine techniques in the treatment of pulmonary bullae.

Oral Health survey at an air base in Jordan

The aim of this investigation was to assess the severity and prevalence of periodontal disease and dental caries in 507 subjects, ranging in age from 15 to 44 years, at an army air base in Jordan. Using the Community Periodontal Index for Treatment Needs [CPITN], it was found that prevalence of periodontal disease increased with age, but incidence of caries, gingivitis and calculus was alarmingly high in young adults [20-24 years]. Overall, the rate of decayed, missing and filled teeth [DMFT] is rising, a trend that has been noted in similar studies from other developing countries
