Exercise capacity in athletes with mouthguards.

The objective of this study was to determine the effect of wearing a mouthguard on maximal exercise capacity and cardiopulmonary parameters at peak workload, and to assess the athletes' attitudes toward wearing a mouthguard. Thirteen volunteer male athletes (18 to 27 years old) were interviewed before and after delivery of a custom-made laminated mouthguard. A visual analogue scale (VAS, 0 - 100 mm) was used for judgment of interference with breathing, speaking, concentration and athletic performance.

A retrospective classification of tooth injuries using a new scoring system.

The WHO classification presently in use categories dental trauma only according to the main injury. A new scoring system will now enable more precise and complete diagnosis of tooth injuries. In an initial retrospective investigation, 100 traumatised teeth were classified according to the WHO and the new scoring systems.

Preoperative radiation and chemotherapy for localized squamous cell carcinoma of the esophagus: a RTOG Study.

Forty-one evaluable patients with localized squamous cell carcinoma of the thoracic esophagus were treated by a course of radiation therapy (3000 cGy in 3 weeks), 5-Fluorouracil (5-FU) and Cis-platinum (Pt). This was followed by an esophagectomy in medically eligible patients who agreed to the procedure and who had no evidence of extrathoracic tumor. If tumor was found in the specimen, an added 2000 cGy of radiation therapy and additional 5-FU and Pt were given.
