The perils of bungee jumping.

Bungee jumping is a relatively new recreational sport. Most emergency physicians and trauma surgeons have limited experience with its associated injuries. We report the case of a bungee cord attachment apparatus malfunctioning, resulting in a free fall of the jumper of approximately 240 feet. The presence of an air cushion on the ground prevented significant injury. Knowledge of the potential injuries of this new sport is crucial for effective management.

Paragangliomas of the carotid body and other rare localisation.

Cervical paragangliomas are uncommon benign or malignant neoplasms, originated by stem cells of neural crest. It is not easy nowadays to define properly their biological behaviour, the possible multiple location and the association with Multiple Endocrine Neoplasms. After a wide review about recent diagnostic, pathological and clinical acquisition, authors report their caseload of 10 patients affected by sporadic paragangliomas and 1 by familial multiple neoplasm localised in carotid bodies of both sides, left vagus nerve and left hypoglossus nerve. All patients but one were treated by a curative resection of the neoplasm. In one case only an explorative laparatomy was possible because of the visceral and vascular involvement.

Small solitary pulmonary nodules: assessment of enhancement and enhancement patterns in benign and malignant tumours by high resolution computed tomography.

Our aim was to determine the accuracy of quantitative and qualitative findings of contrast-enhanced computed tomography (CT) by means of differential analysis of small uncalcified solitary pulmonary nodules and to compare the CT diagnosis with the results of transthoracic needle biopsies (TTNB). We assessed a consecutive series of 109 patients with 66 malignant or 45 benign pulmonary nodules before TTNB and surgery with contrast and high resolution computed tomography (HRCT). Pulmonary nodules were classified as small when equal to or smaller than 15 mm and large when larger than 15 mm. Diagnostic accuracy of CT qualitative evaluation was 95% for large nodules and 92% for small nodules. Specificity was 92% for small nodules, 80% for large nodules. Enhancing regular septa were observed in 28 hamartomas (80%) while except for two cases (3%), inner septa were absent or irregular in malignant tumours. TTNB accuracy was 70% for small nodules and 94% for large ones. Low-enhancing hamartomas are more frequent in Italy than in the US where the prevalence of high-enhancing granulomas in benign nodules reduces the specificity of quantitative CT analysis. We propose that certain geographic areas would benefit from enhanced-CT in place of TTNB in managing lung nodules equal to or less than 1.5 cm.

[Cholecystectomy and colorectal cancer: a retrospective study of a sample of 285 operated patients].

A review of 285 patients operated for colo-rectal cancer in order to evaluate cholecystectomy rate in their pathologic history is reported. A surprisingly high rate (9.47%) was registered also when compared with Literature data. Although not definitely conclusive for a positive correlation between cholecystectomy and colo-rectal cancer, the Authors believe that this study identifies a subgroup of patients potentially at risk for colo-rectal cancer. In these subjects a prophylactic, periodic colonoscopy could be useful.
