[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

[Clinical and phmetric evaluation of gastro-esophageal reflux impact on upper airways in adult]

Gastroesophageal reflux is a frequent and benign affection. It represents an etiopathological entity in otorhinolaryngology; that may occasion a large variety of ENT manifestations. To evaluate clinical and pHmetric impact of gastro esophageal reflux on upper airways in adult. Prospective study about 95 cases diagnosed and treated at the ENT department of military hospital of Tunis. Clinical features, pH metric profiles and therapeutic approach are reported and compared to the literature. The mean age was 37 years old. Sex ratio was 1.16. Pharyngolaryngeal symptoms dominated ENT manifestations [41 cases]. Laryngeal dyspnea, cough and dysphonia were predictive of danger. Positive pH metric rate collated to posterior laryngitis and pharyngitis were respectively 81.2% and 79.1%. Posterior laryngitis, dental erosion and chronic sinusitis, seem to have pejorative significance. Otorhinolaryngologist must think about asymptomatic reflux every time when chronic or recurrent ENT affection remain unexplained after complete clinical investigations. PH monitoring confirms gastroesophageal reflux disease
