ABSTRACT
AIM: Human papillomavirus is the most common cause of sexually transmitted disease. It is associated with immunosuppression and shows a marked tendency to recur. We investigated a natural immunostimulant aimed to reduce recurrence. METHOD: A randomized controlled study was carried out including 261 patients allocated to surgical excision alone (control group; n = 122) and surgical excision plus postoperative immunostimulation for 30 days with a natural product (STET; study group; n = 139). Patients with HIV positivity were excluded. All patients gave fully informed consent. RESULTS: The patients were followed for 6 months after surgery. Recurrence occurred in 7.2% (10/139) in the study group and in 27.1% (33/122) in the control group (P < 0.0001). There were no significant differences in the sex, sexual orientation, number of lesions, time to diagnosis and treatment or localization of lesions in the two groups. CONCLUSIONS: Immunostimulation using a natural product significantly reduced the incidence of recurrence of anal condylomata in patients undergoing surgical excision.

OBJECTIVES: To examine the accuracy of transcranial Doppler to detect cerebral vasospasm in a patient population with aneurysmal subarachnoid hemorrhage. DESIGN: Prospective blind comparison of transcranial Doppler with cerebral angiography. Diagnostic accuracy of transcranial Doppler was assessed using receiver operating characteristic (ROC) analysis and likelihood ratios. Sensitivity and specificity were calculated using directly measured middle cerebral artery diameter as reference standard. SETTING: Intensive Care Unit of a large university teaching hospital. PATIENTS AND PARTICIPANTS: Twenty-two patients with subarachnoid hemorrhage were included. Patients underwent angiography on admission and after 8 days to diagnose vasospasm and were defined as having clinical vasospasm, angiographic vasospasm, or no vasospasm. MEASUREMENTS AND RESULTS: Sensitivity and specificity were 1.00 and 0.75 for angiographic vasospasm and both equal to 1.00 for clinical vasospasm diagnosis. A transcranial Doppler mean velocity threshold value of 100 cm/s for angiographic vasospasm and 160 cm/s for clinical vasospasm detection were chosen by ROC analysis. CONCLUSIONS: A Transcranial Doppler mean velocity threshold of 160 cm/s, calculated by the ROC analysis, accurately detects clinical vasospasm. A daily transcranial Doppler examination performed by a trained operator should be routinely used to provide early identification of patients at high risk and to orient therapeutic decisions.
