Videoconferencing: what are the benefits for dental practice?

For more than 3 years members of the TeleDent team from Bristol University have been looking at the potential of videoconferencing technology for dentistry. Here they explain what videoconferencing is and how it can help the GDP. They discuss examples of its most promising uses for the profession, which include professional updating and providing diagnostic support at a distance. They describe the equipment that is needed, the different types of system available and give an indication of costs. A suggested procedure for using the technology for remote referrals is outlined. 'Store and forward' techniques are also discussed. These do not involve a live video but involve the sending of static electronic files. This approach is compared with videoconferencing, and the article looks at the question of which will be best suited to the GDP, and for what purposes.

Urologic complications of hip arthroplasty.

Significant intrapelvic injuries from routine hip surgery are rare but may result in long-term urologic morbidity. Two illustrative cases are presented with attention given to the close anatomic proximity of the intrapelvic structures to the hip joint and their potential for injury after hip surgery. A review of similar cases with their management is presented.

Penile carcinoma in renal transplant recipient.

A case of squamous cell carcinoma of the penis occurring in a renal transplant recipient is presented. Despite a markedly increased incidence of epidermoid carcinoma in the transplant population, this is the first reported case of penile carcinoma occurring in a renal transplant recipient. As with other superficial epithelial tumors in this population, conventional therapeutic techniques are recommended. However, excisional biopsy is recommended for penile lesions at the time of initial presentation or if any clinical suspicion exists.

Morphology and pathogenesis of adrenal cysts.

Adrenal cysts represent a rare condition (approximately 250 cases have been reported). We report two additional cases: the first involved a huge lesion removed surgically and thoroughly studied preoperatively; the second was an incidental autopsy finding. Detailed ultrastructural studies have been made of both cases. We think that the basic cell of origin of the cyst is an endothelial cell lining lymphatic channels. We speculate that the pseudocysts, which have been described as having a fibrous lining, probably were at one time also lymphendothelial but, perhaps due to trauma or repeated bleeding, the major portion of the endothelial lining became replaced by collagen. The primary and secondary cystic malignancies and cases of cysts due to parasites should be classified separately from the adrenal cysts of lymphendothelial origin which probably represent a benign tumor-like overgrowth.

Metastatic infection secondary to genitourinary tract sepsis.

Metastatic infections arising from sepsis in the genitourinary tract are reviewed in 175 cases, including five in which we treated the patients. The skeleton was the most common site of metastasis (59 per cent). The endocardium was next most frequently involved (28 per cent). Gram-negative organisms were implicated in less than two-thirds of the cases (59 per cent). Impaired host defense mechanisms were noted in 25 per cent of the patients experiencing metastatic infections. The lower urinary tract was the source of metastasis in 75 per cent of the patients, particularly after urologic manipulation in men. Women were more likely to experience metastatic infection from the upper urinary tract. Anatomic and pathologic considerations explaining these sex differences are presented.

Management of prostatic fistulas.

Prostatic fistulas communicating with the rectum or perineal skin are unusual complications of a prostatic operation, pelvic trauma, prostatic abscess or other iatrogenic injury. A third of these fistulas may close spontaneously with proper urinary drainage and avoidance of fecal soilage. The many operative procedures described for the repair of these fistulas indicate that no ideal method of repair can be applied to every case. Operative management should be mandated by the size, location and duration of the fistula as well as by the surgeon's experience with the various anatomic approaches.
