[Performances of imaging investigations and scintigraphy for pre operative hyperparathyroidism]

Hyperparathyroidism is a frequent affection. Therapeutic management is based on surgical removal of pathological glands. Therapeutic results are ameliorated thanks to preoperative imaging approach. To evaluate performances of different imaging investigations and scintigraphy for preoperative parathyroid localization. Retrospective study about 26 patients with confirmed hyperparathyroidism. After radio-surgical and histological correlation, scintigraphy showed the best rate of sensitivity [92.3%], compared to other morphologic imaging [ultrasonography: 66.6%, CT-scan: 33.3% and MRI: 66.6%]. The specificity was the same [100%]. No difference was obseved for both scintigraphic modalities. Our results compared to the literature showed that scintigraphy is the most satisfying for preoperative localization of abnormal parathyroid glands in hyperparathyroidism

[Chronic laryngitis in adults]

Chronic laryngitis is a lingering inflammation of the laryngeal mucosa, caused by specifc aetiology and often irritative factors. To discuss clinic and therapeutic aspects of the pathology. We report a retrospective study about 25 patients treated and followed for non specific chronic laryngitis over a period of 11 years [1994-2004]. The average age of the patients was 54, 2 years. Tobacco intoxication was noted in 72,7 of cases and Gastroesophageal reflux in 2 cases. The endoscopic examination of laryngeal lesions, realized in all cases, notes laryngeal keratosis in 88% of cases and congestive laryngitis in 12%. Histological analysis of the lesions reveals a dysplasia in 44% of cases. Clinical and endoscopic follow up of the patients discover malignant development in 5 patients. The treatment of chronic laryngitis is based on the suppression of etiologic factors and on laryngeal microsurgery with micro instruments and with laser techniques
