[Small-dose vardenafil restores erectile function after penile surgery].

Objective: To investigate the impact of penile surgery on the erectile function of the patient and to evaluate the role of small-dose vardenafil in restoring the impaired penile erection.

Methods: Sixty cases of penile cavernosum surgery were equally and randomly divided into a vardenafil and a control group, the former treated 5 - 7 days after surgery with 10 mg vardenafil every other day, while the latter given vitamin E at 100 mg once a day, both for 12 weeks. The penile erectile function of the patients was evaluated with the IIEF-5 questionnaire before surgery and at 3 and 6 months after vardenafil medication.

Study on changes of partial pressure of brain tissue oxygen and brain temperature in acute phase of severe head injury during mild hypothermia therapy.

Objective: To study the changes of partial pressure of brain tissue oxygen (PbtO2) and brain temperature in acute phase of severe head injury during mild hypothermia therapy and the clinical significance.

Methods: One hundred and sixteen patients with severe head injury were selected and divided into a mild hypothermia group (n=58), and a control group (n=58) according to odd and even numbers of hospitalization. While mild hypothermia therapy was performed PbtO2 and brain temperature were monitored for 1-7 days (mean=86 hours), simultaneously, the intracranial pressure, rectum temperature, cerebral perfusion pressure, PaO2 and PaCO2 were also monitored.
