Purpose Of Review: Augmented reality (AR) is becoming increasingly popular in modern-day medicine. Computer-driven tools are progressively integrated into clinical and surgical procedures. The purpose of this review was to provide a comprehensive overview of the current technology and its challenges based on recent literature mainly focusing on clinical, cadaver, and innovative sawbone studies in the field of orthopedic surgery.

Multimodal analgesia is best for postoperative pain management; however, opioid therapy is still the main treatment for pain after surgical procedures. Transdermal buprenorphine is a partial μ-agonist opioid widely used for chronic pain syndromes, with limited evidence for acute postoperative pain.

The purpose of this paper is to present a review of the state-of-the-art in virtual needle insertion training simulation based on haptic interaction. A systematic review method was applied to gather documentation that enables a rigorous audit of the process stages and results.

Methods:: Thirty-six rats were subjected to a 4cm dorsal longitudinal incision. Twelve were sub-jected to simple suture with polyamide 6-0, 12 rats underwent wall synthesis using Dermabond(r) and 12 was performed cutaneous synthesis with N-2-Butyl-Cyanoacrylate.
Introduction: Ischemic postconditioning has been recognized as effective in the prevention of reperfusion injury in situations of ischemia and reperfusion in various organs and tissues. However, it remains unclear what would be the best way to accomplish it, since studies show great variation in the method of their application.
Objective: To assess the protective effect of ischemic postconditioning on ischemia and reperfusion in rats undergoing five alternating cycles of reperfusion and ischemia of 30 seconds each one.
Objective: Identify prognostic factors associated to late urinary toxicity in patients with prostate cancer submitted to radical conformal radiotherapy (3DCRT).
Materials And Methods: From July 1997 to January 2002, 285 patients with localized prostate cancer were consecutively treated with 3DCRT and retrospectively analyzed. Thirty seven (13%) patients were submitted to transurethral prostate resection previously to 3DCRT.
Objective: Assess the results of salvage conformal radiotherapy in patients with biochemical failure after radical prostatectomy and identify prognostic factors for biochemical recurrence and toxicity of the treatment.
Materials And Methods: From June 1998 to November 2001, 35 patients were submitted to conformal radiotherapy for PSA > or = 0.2 ng/mL in progression after radical prostatectomy and were retrospectively analyzed.
Purpose: To evaluate the prognostic factors associated with overall survival in patients with brain metastasis treated with whole brain radiotherapy (WBRT) and estimate the potential improvement in survival for patients with brain metastases, stratified by the Radiation Therapy Oncology Group (RTOG) recursive partitioning analysis (RPA) class.
Patients And Methods: From January 1996 to December 2000, 270 medical records of patients with diagnosis of brain metastasis, who received WBRT in the Hospital do Cancer Sao Paulo A.C.
Background: Nasopharyngeal carcinoma in childhood is rare. Radiochemotherapy is considered the standard treatment and yields increased survival and local control rates. In this article, the authors report on the results from the multidisciplinary treatment of pediatric patients who had nasopharyngeal lymphoepithelioma with radiochemotherapy, including high-dose-rate brachytherapy of the primary tumor site.

Purpose: This retrospective analysis reports the results on patients with anal canal carcinoma treated by combined radiotherapy and chemotherapy.
Methods And Materials: Between March 1993 and December 2001, 43 patients with anal canal carcinoma were treated with radiochemotherapy at the Hospital do Cancer A.C.
