A new method called PAIR (Puncture-Aspiration of cyst contents--Injection of hypertonic saline solution--Reaspiration) was used as a percutaneous treatment of hydatid cysts. In 37 patients, 120 cysts were punctured. All patients had not been considered surgical candidates. The cysts were localized in the liver, peritoneum, spleen, kidneys, muscles, and bones. In 70% of patients, good results were obtained. Recurrence occurred in 5 of 120 cysts, all at the beginning of our experience when a low concentration of sodium chloride solution was injected. Moderate allergic reactions occurred during seven cyst aspirations. No anaphylactic shock, sudden deaths or dissemination of cyst contents were observed.

Scoliotic patients underwent many radiological examinations during their control and treatment periods. Nowadays, few studies have calculated effective dose which is the primary indicator of radiation risk. In this study, the PCXMC program is used to calculate the effective doses associated with scoliosis radiography. Five age groups of patients, proposed by the National Radiological Protection Board, have been chosen: <1, 1-4, 5-9, 10-15 and ≥16 y (adult patients). Patient and radiographic data were collected from 99 patient examinations for both anteroposterior and lateral full spine X-ray projections. Results showed the effective dose ranged from 118 to 1596 μSv for the frontal projection and from 97 to 1370 μSv for the lateral projection, with patient age varying from 3 months to 22 y. This study presents the effective dose against patient age and demonstrates the necessity to optimise patient protection for this type of examination.
