INTRODUCTION Adequate bleeding control is essential for the success of periapical surgery. The aim of this study was to evaluate the effects of 2 hemostatic agents on the outcome of periapical surgery and their relationship with patient and teeth parameters. METHODS A prospective study was designed with 2 randomized parallel groups, depending on the hemostatic agent used: gauze impregnated in...

BACKGROUND AND OBJECTIVES Transumbilical laparoscopic-assisted appendectomy (TULAA) carries a high risk for surgical site infection. We investigated the effect of a bio-occlusive umbilical vacuum dressing on wound infection rates after TULAA for patients with acute appendicitis and compared to it with a conventional 3-port appendectomy with a nonvacuum dressing. METHODS This study was a retro...

Purpose The purpose of this study was to evaluate the efficacy of Betafoam in terms of wound healing and safety. Methods Fifty-four male adult Sprague-Dawley rats (weight, 200-250 g) were used in the study. Full-thickness skin defects were created on the back of each rats. The rats were assigned to 6 groups according to the type of wound dressing used (n = 9 for each group): Betafoam, Allevyn...

Early coverage of large burn wounds is often limited by the availability of donor sites for skin grafts. One solution to this problem is the use of cultured epithelial autografts, whereby a small sample of uninjured skin is obtained from the patient and its keratinocytes are grown in a cell culture environment. Over a three to four week period the number of cells can be expanded more than 5000-...

This paper describes the preparation of Pt- or W-supported Pt nanowires by directly growing them on the surface of Pt or W gauze. The growth direction of the nanowires was determined to be along the <111> axis. Electrochemical measurements were performed to investigate their catalytic performance toward methanol oxidation. It was found from cyclic voltammetry that the Pt nanowires supported on ...

BACKGROUND Uncontrolled hemorrhage is a well-recognized cause of mortality in trauma victims and the control of active hemorrhage is among the initial steps in resuscitation. OBJECTIVES The purpose of this study was to assess the role of a hemostatic agent "celox" in the management of civilian stab-wound trauma. PATIENTS AND METHODS In this clinical trial study, 160 patients with penetratin...

Control of bleeding is essential during oral procedures. Although various chemical agents have been introduced and tested, hot water dressing has not to our knowledge been assessed before. Studies of operations for epistaxis or sinus conditions have suggested that irrigation with hot water can reduce bleeding, so we hypothesised that it might be effective in reducing bleeding after extraction t...

Molecular mechanisms governing peritonitis caused by the presence of aseptic gauze have remained unclear. To identify the genes involved, sterile gauze-exposed omentum was collected at 0, 6, 12, 24, and 48 h intervals, and analyzed by differential display RT(reverse transcription)-PCR. Among over 1,200 bands, 230 bands were found differentially expressed. These bands represented the fragment si...

This report describes a case in which a consciousness disturbance was associated with a high plasma iodine level and which improved after the removal of iodoform gauze that had been applied to infected wounds. A 71-year-old male with poorly controlled diabetes underwent a laminectomy for an epidural abscess. On the 6th and 8th postoperative days, he underwent debridement for fasciitis in the bo...

Quikclot has been used many years for treating external hemorrhage in the battle field. In this study, the hemostatic performance of NZG-JY (natural zeolite granules from Jinyun, China) was evaluated and compared with Quikclot in a lethal rabbit model of complex groin injury. Fifty-six anesthetized rabbits were randomized to three different groups: (1) NZG-JY (n = 19); (2) Quikclot (n = 19); an...
