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.

BACKGROUND: The purpose of this study was to compare the clinical outcome in patients aged less than 55 years who underwent arthroscopic tenodesis and arthroscopic repair for type 2 superior labrum anterior and posterior (SLAP) lesions. METHODS: Between April 2008 and December 2014, surgery was performed on a total of 45 patients with isolated type 2 SLAP lesions. Arthroscopic repair was performed in 22 patients and arthroscopic tenodesis was performed in 23 patients. In both groups, the clinical outcomes at follow-ups were evaluated using the University of California at Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and visual analogue scale (VAS) score. RESULTS: In both groups, the VAS scores for pain had improved significantly throughout the postoperative follow-up period. The VAS score showed a statistically significant difference at postoperative 3 and 6 months (p<0.05); however, there was no statistically significant difference between preoperative and postoperative results at 12 months (p>0.05). In both groups, the functional outcome was statistically improved postoperatively. In a comparison of the UCLA and ASES scores between the two groups, there was a statistically significant difference at postoperative 3 and 6 months (p<0.05), but there was no statistically significant difference between preoperative and postoperative results at 12 months (p>0.05). CONCLUSIONS: Based on the results of this and other studies, patients with isolated type 2 SLAP lesions showed better short-term clinical outcome with tenodesis than with repair. However, there was no difference between the two groups at the final follow-up.

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.

Gastrointestinal cytomegalovirus(CMV) infection in adults is observed as a part of a generalized or localized infection in patients who are immunocompromized. We report a case of CMV infection of the small intestine. The patient is a 34 year-old woman who has complained of palpable purpura in the lower extremities and buttocks, and arthralgia of large joints. The skin biopsy showed fibrinoid necrosis and neutrophils with leukocytoclasis, which findings are compatible with hypersensitivity angiitis. The patient received steroid and cyclophosphamide. During the follow-up period, generalized edema and bloody stool were detected. Resected specimen of small bowel has multiple aphthous ulcer. Microscopically, cytomegalic cells are observed along the endothelial cells and mesenchymal cells. In situ hybridization using DNA probes against CMV revealed positive staining in the cytomegalic inclusions in vascular endothelial and mesenchymal cells.
