BACKGROUND: The purpose of this study was to examine the effects of a single administration of vascular endothelial growth factor (VEGF) in promoting the angiogenesis and thereby reducing the formation of capsular contracture. METHODS: We treated 24 female Sprague-Dawley rats with (1) 5 mM Tris Buffer and 150 mM NaCl 0.1 cc, (2) VEGF 15 µg/0.1 cc, (3) VEGF 150 µg/0.1 cc during placement of the implant, or (4) VEGF 150 µg/0.1 cc and VEGF 300 µg/0.2 cc. We histopathologically measured the thickness of the capsule and the number of blood vessels. RESULTS: All experimental groups had a significant difference in the thickness of the capsule compared to the control group (P<0.001). There was no significant difference between experimental group 2 and experimental group 3. The number of blood vessels formed around the capsule was significantly greater in all the experimental groups compared with the control group (P<0.05). There was no significant difference between the experimental groups. There was a significant negative correlation between the thickness of the capsule and the number of blood vessels (Spearman's correlation coefficient, 0.2732; P<0.0001). CONCLUSIONS: A single administration of VEGF reduced formation of the capsule and increased the vascularity around the implant, supporting the hypothesis that prevention of tissue ischemia can be a treatment strategy for capsular contracture.

Background: We hypothesized that intravenous lidocaine mixed with propofol may have an influence on anesthesia induction and hemodynamic responses to propofol induction and endotracheal intubation as well as propofol-induced pain on injection. Methods: Seventy-five patients were allocated to group L1 (2% lidocaine 1.5 mg/kg, n=25), group L2 (2% lidocaine 2 mg/kg, n=25) or group C (normal saline 0.05 mL/kg, n=25) according to the lidocaine dosage mixed with propofol 2 mg/kg. The pain on injection was scored as none, mild, moderate, and severe. The site of pain and recall of pain were also recorded. Loss of verbal response was observed during induction. Mean arterial blood pressure (MAP) and heart rate (HR) were recorded before anesthetic induction (baseline value), immediately before and after endotracheal intubation, and every min until 5 min thereafter. Results: Ninety-two percent of patients reported pain upon injection in group C, whereas 8% of the patients in group L1 and no patient in group L2. Loss of verbal response before injection of total dose of propofol was observed in 44% in group L2, 36% in group L1 and 28% in group C. Lowered MAP caused by propofol increased significantly after endotracheal intubation in all three groups (p<0.05). HR increased immediately and 1 min after endotracheal intubation in all three groups (p<0.05). Conclusions: Our results indicate that intravenous lidocaine 1.5 mg/kg or 2 mg/kg mixed with propofol 2 mg/kg significantly reduces the incidence and the degree of pain, but does not affect anesthesia induction and hemodynamic responses to propofol and tracheal intubation.

Tendon disorders commonly cause wrist and hand disability and curtail the performance of work-related tasks. Sonography allows for cost-effective, noninvasive, and dynamic evaluation of soft tissue structures, thus representing a valuable tool for ruling out musculoskeletal disorders of the wrist and hand. Because of the complexity of the wrist joint, sonographic training and familiarity with normal and variant anatomy are needed to avoid misdiagnosis and improper treatment. The purpose of this article is to demonstrate the structures representing normal findings during sonographic evaluations of the wrist and hand. The main reviews the gross anatomy and procedures that are recommended to assess the soft tissue structures of the wrist and hand, with particular emphasis given to tendons, nerves, and ligaments. In conclusion, sonography is effective in assessing the tendons of the hand and wrist and related disorders and represents a valuable tool for diagnosis.
