Fifteen years experience with pulmonary hydatidosis in Zahedan, Iran

Hydatid disease is a major world health problem and pulmonary hydatidosis is a widespread disease. It is presented with different clinical manifestations. In order to determine the most clinical manifestation, diagnostic methods and clinical outcome in our patients, we conducted this study. Forty-nine patients with pulmonary hydatid cysts who were admitted to our hospital in Zahedan [Southeast of Iran] between 1990 and 2005, evaluated. We retrospectively reviewed the patients' symptomatology, diagnostic studies, treatment options, and morbidity as well as mortality rate. The ages of the patients ranged from 16 to 68 years [mean 43 years]. Seventy-five percent of patients were from male gender. Hemoptysis was one of the most common clinical presentations in our patients. Radiological studies were the main diagnostic tool. The correct preoperative diagnosis was made in 92% of the patients by chest roentgenogram plus chest CT-Scan. Eighty seven percent of patients were treated by surgical route. Only one patient was expired during surgery. Upon the results emerged from this study, hemoptysis is one of the most prevalent clinical manifestation in patients with pulmonary hydatidosis and it can mimic pulmonary tuberculosis in endemic area

Evaluation of interproximal caries with using of bitewing radiography in dental student of Islamic Azad University

Statement of Problem: Dental caries is one of the common diseases in the world. It is an infective disease which is caused by loss of minerals and destruction of dental tissues. One of the most effective ways to diagnose the interproximal caries is radiography. Bitewing radiography is the best way for caries diagnosis

Purpose: The aim of this study was to evaluate the prevalence of the interproximal caries in dental students of Islamic Azad University

Materials and Methods: This research was a cross sectional study that was conducted on 89 students of the Azad University consisting of 48 females and 41 males who were selected by random sampling. For each individual student left and right posterior bitewing radiographs were taken with a standard method [the interproximal spaces were between 6- 7, 5, 6 and 4, 5]. Thus 12 interproximal spaces were examined in each individual. The most proximal cavitation surfaces were detected in the upper Jaw

Results: Results revealed that 6 individuals [6.7%] were totally caries free and 83 individuals [93.3%] showed interproxmal caries. Out of 1068 proximal spaces which had been studied 794 Spaces [73.4%] were caries free and 274 surfaces [25.7%] had caries

Conclusion: The high incidence of proximal caries and the possibility of missing them in the routine examinations make the bitewing radiographs an effective procedure for diagnosis
