This study was conducted to determine the safe intravitreal dosage of ciprofloxacin. Twenty-four phakic eyes of New Zealand pigmented rabbits were used. Each group(4 eyes) received midvitreal ciprofloxacin of 100, 200, 400, 600, 800 micro gram in 0.1ml BSS Plus, or 0.1ml BSS Plus only as control. We evaluated retinal function by measuring the electroretinograms for a graded series of flash intensities and fitting b-wave amplitudes to the Naka-Rushton equation. At a dose of greater than 600 micro gram, Rmax decreased signifantly and log K increased signifantly. N-value decreased slightly. B-wave amplitude decreased as a toxic response of intravitreal ciprofloxacin in a dose dependent manner, and this response was best detected using lower luminance stimuli. Lower luminance electroretinography revealed a significant decrease in b-wave amplitude in eyes injected with a dose of 400 micro gram or more. We concluded that 200 micro gram will be the safe intravitreal dosage of ciprofloxacin in phakic rabbit eyes.

[Objective] To determine the long term survivorship and establish the idea I correction angle in proximal tibial osteotomy for primary osteoarthritis. [Method] Seventy-nine patients suffering from primary osteoarthritis (111 knees) were performed with proximal tibial valgus osteotomy from 1985 to 1997, among which 74 women (106 knees) and 5 men (5 knees). The age ranged from 37 to 70 years (mean, 55 years). Postoperatively, hospital for Special Surgery knee score (HSS) was used for clinical assessment. The femorotibial angle (FTA) was measured to classifiy patients to group Ⅰ of 61 knees with less than 7 of valgus; group Ⅱ of 23 knees with 7～9 of valgus; group Ⅲ of 27 knees with over 10 of valgus. Closed wedge osteotomy was performed in all cases. HSS was assessed pre-and post-operatively. [Result] The average follow-up period was 9 years and 6 months (2 years and 4 months to 14 years and 1 month). The HSS knee score averaged 60 points preoperatively, 94 after 1 year and 87 at the last follow-up. Falure I was the need for conversion of a proximal tibial osteotomy to a total knee arthrop lasty, and Failure Ⅱ was the need for conversion of HSS knee score of less than 60 points. The 4 and 14 years survival rates were 99% and 85% using the first definition of failure, and 96. 4% and 75.1% using the second. [Conclusion] Proximal tibial osteotomy is reliable for treating unicompartmental osteoarthritis, providing that the postoperative femorotibial angle is corrected to more than 7° of valgus and falls in the range of 10°～15°.

TO determine the normal neonatal adrenal gland size, ultrasonographic examinations were performed in 145 newborn infants. They were divided into 3 groups according to the days of age. The group I is 1~3 days, group II is 6~9 days and group III is 21~50 days of age. 1) The adrenal gland size was as follows. In group I, the length was 29.05mm and the width was 4.02mm. In group II, the length was 24.04mm and the width was 2.79mm. In group III, the length was 19.54mm and the width was 2.21mm. 2) With increasing age, the size of adrenal gland became smaller. 3) The size of adrenal gland correlated well with the birth weight and height. We conclude that the ultrasonographic examination is useful in infant adrenal gland disease.

BACKGROUND: Laryngomicrosurgery has some special characteristics. It is stressful due to intubation and direct laryngoscopy during a short operation time. Therefore both adequate anesthesia and quick recovery for the slience therapy after the operation are needed. This study compared the cardiovascular responses and recovery pattern between propofol and Thiopental-Enflurane anesthesia. METHODS: Sixty outpatients of ASA class 1 or 2 for microlaryngoscopy were randomly assigned to receive either anesthesia with propofol (Group P, n = 30) and thiopental-enflurane (Group E, n = 30). Group P was induced with propofol 2 mg/kg and succinylcholine 1 mg/kg and maintained with vecuronium 0.04 mg/kg, propofol 10 - 6 mg/kg/h, and N2:O2/3 L/min:2 L/min. Group E was induced with thiopental 5 mg/kg and succinylcholine 1 mg/kg and maintained with vecuronium 0.04 mg/kg, enflurane 1 3 vol%, and N2O:O2/3 L/min:2 L/min. Ketorolac (30 mg) and hydrocortisone (100 mg) were added for postoperative pain in both groups. The changes in blood pressure and heart rate, pre and post induction, were compared in both groups. In addition, we compared energence time and the state of recovery (Steward's score) 5 minutes and 15 minutes after extubation and the frequencies of other complications. RESULTS: No significant differences in age, wt, sex and anesthesia time of the two groups were observed. Mean arterial pressures were significantly different after anesthesia and after intubation between the two groups. However the heart rates were not different among the groups. The extubation time was significantly shorter in Group P. The recovery score at 5 min and 15 min after extubation was significantly higher in Group P. CONCLUSIONS: We conclude that propofol with nitrous oxide may be useful in laryngeal microsurgery, especially, when silence therapy is needed.

This report describes clinical cases of a palato-gingival groove on a maxillary lateral incisor with associated localized periodontal disease and pulp necrosis. The tooth of the first case was extracted because of severe bone destruction. The palato-gingival groove of the second case was eliminated using a round bur, and the resulting defect was filled with synthetic graft and covered by an absorbable membrane. Both diagnosis and treatment of palato-gingival groove were very difficult and usually extraction of the involved tooth is the treatment of choice, but combined endodontic-periodontic treatment allowed the tooth to be saved.

PURPOSE: To evaluate the effect and safety of subconjunctival bevacizumab injection immediately after primary pterygium surgery. METHODS: From October 2010 to June 2011, 54 patients (54 eyes) with primary pterygium who had received pterygium excision with the bare sclera technique were evaluated. Twenty-seven patients (27 eyes) in the bevacizumab group received a subconjunctival injection of 5 mg (0.2 ml) bevacizumab and 27 patients (27 eyes) in the control group received a subconjunctival injection of 0.2 ml balanced salt solution immediately after surgery. At the 6-month follow-up, the degree of fibrovascular tissue proliferation, the recurrence rate of pterygium and the effect of wound healing were analyzed prospectively. RESULTS: One month after the surgery, the degree of fibrovascular tissue proliferation was inhibited in the bevacizumab group compared to the control group (p = 0.028). However, 3 to 6 months after surgery, there was no significant difference between the 2 groups. In addition, there was no significant difference between the 2 groups in the recurrence rate of pterygium and wound healing after surgery. CONCLUSIONS: Subconjunctival bevacizumab injection after primary pterygium surgery inhibited the degree of fibrovascular tissue proliferation for 1 month and safe for wound healing. Subconjunctival bevacizumab injection has the potential for adjunctive therapy after pterygium surgery.

Most of the malignant tumors of the pancreas are adenocarcinomas arising from the ductal epithelium. Primary leiomyosarcoma of the pancreas, even though it is the most common sarcoma of the pancreas, is very rare. We present a case of leiomyosarcoma of the pancreas, probably primary, with metastases to the stomach, lymph nodes, and abdominal wall. A 52-year-old woman visited the hospital with vague right upper abdominal pain and weigh loss of 6 kg for 2 months. The radiological and endoscopic examination revealed that she had a large heterogeneous mass, 11 cm in size, in the pancreatic body and tail, a 4 cm-sized mass in the paraaortic area, and a 3 cm-sized polypoid mass in the stomach. Histologically, they were all similar to one another and composed of markedly pleomorphic cells. Immunohistochemical and electron microscopic studies showed definite smooth muscle differentiation of the tumor cells. Two months later, the patient underwent an excision of a new 3 cm mass in the right lower abdominal wall, showing features of well differentiated leiomyosarcoma.
