ABSTRACT
Duplex sonography is now the gold standard for the non-invasive study of cavernous arteries. Many authors consider that this technique allows for the exploration of the veno-occlusive system and can detect venous leakage. The most common criteria is an end diastolic velocity > 5 cm/s, measured in the cavernous arteries. In a retrospective study, 34 impotent patients were reviewed. All of them were explored both by doppler sonography and pharmacocavernosometry to assess the efficacy of duplex sonography in detecting venous leakage. The data show that the doppler detects venous leakage in only 41%. The specificity and the sensitivity are both 50% which is clearly disappointing. Therefore, in our experience, duplex sonography is not a reliable technique to detect venous leakage. We consider that the best method is still pharmacocavernosometry.

Head and neck complications due to dental infections. Six cases of deep neck infection are reported. The odontogenic origin was confirmed in five patients. In one case, the aetiology remained unknown. All case reports are discussed emphasizing cervical space anatomy, mixed microbial flora and potential iatrogenic treatment.

A review of 20 cases of conservative surgery for urothelial tumors of the upper tract is presented. The morbidity is limited; the recurrence rate is around 15% in the ipsilateral urinary tract with a mean follow up of 41 months. Conservative surgery does not seem to carry a higher fatal risk as compared to more radical surgery. It has indications in some cases which are defined.
