Infection with human papillomavirus (HPV) has been clearly established as the central cause of cervical cancer. This Phase IV, observer-blind study is designed to evaluate the safety and immunogenicity of Cervarix in HIV infected females aged 15 to 25 years as compared to Merck's HPV vaccine (Gardasil). For comparative purposes, a group of HIV negative females will also be evaluated. All subjects will receive the HPV vaccine (either Cervarix or Gardasil) according to a three-dose schedule (Day 0, Week 6, Month 6).
Twin pregnancies are at substantial increased risk of preterm delivery. Prophylactic administration of progesterone in singleton pregnancies at risk of preterm delivery has been shown to be effective in reducing the rate of such complication.

Repair of the rotator cuff has high rates of re-rupture (20-54%), despite good clinical results. Several ways to improve the healing tendon-bone are currently studied, among them the most used is the use of growth factors. The platelet-rich plasma is a source of several growth factors, and is already used in various orthopedic procedures. The aim of this study is to evaluate the effectiveness of platelet-rich plasma in improve tendon-bone healing in arthroscopic rotator cuff repairs.
Fibromyalgia is a rheumatologic syndrome characterized by widespread chronic pain, tender points and other symptoms as fatigue, sleep disturbances, anxiety and depression. Therapeutic exercises are described as an important form to management of symptoms. This study aims to assess strengthening and stretching exercise efficacy in symptoms and quality of life of Fibromyalgia patients. The study is done at General Clinical Hospital of Medicine Scholl of University of Sao Paulo. 63 subjects undergo the study and they are divided into three groups: 1 strengthening exercise, 2 stretching exercise and 3 control group. Patients are evaluated by following instruments: Fibromyalgia Impact Questionnaire, Medical Outcomes Study 36-item Short-Form Health Survey (SF-36), Stanford Health Assessment Questionnaire, dolorimetry at tender points by a Fischer dolorimeter, finger-to-tip floor test for muscular flexibility, dynamometer EMG System do Brasil for strength test of extension and flexion of knees and elbows, time to get up and go test, functional reach test, sit-to-stand test. Subjects of 1 strengthening exercise group undergo a global strengthening program and 2 stretching exercise group undergo a global stretching program. All programs have 12 weeks of duration and physical therapy is twice a week. The control group does not do any intervention during 12 weeks and after the second evaluation they enter the common program of physical therapy. Data are being analyzed by descriptive and interferential statistics procedures.
The purpose of this study is to determine whether nilotinib is efficacious in the treatment of metastatic and/or inoperable melanoma harboring a c-Kit mutation.

The purpose of the study is to determine whether implantation of a multifocal IOL with a modified addition at lens plane(Restor +3) results in better intermediate visual acuity with similar performance at distance and near compared to other multifocal IOL with similar design but with higher addition at lens plane. Patient's contrast sensitivity of vision and best reading distance following Restor +3 implantation were also assessed. Study hypothesis: the implantation of an intraocular lens (IOL) with a modified addition at lens plane (restor +3, Alcon Laboratories,Inc) results in better intermediate visual acuity with similar distance and near visual acuity after cataract surgery.
