The authors studied 410 cases of strabismus patients who visited our clinic from 1973 to 1978 Among them, 170 cases of esotropia, 234 cases of exotropia and 6 cases of hypertropia were observed. The average age at the time of onset was 3.4 years in esotropia and 5.2 years in exotropia. Visul acuity in exotropia was relatively good. 0.7 or more visual acuity was 53 % in exotropia and 34.7 % in exotropia. Refractive status, hypertropia above 1.5D was 64. 2 % in esotropia, but, no specific correlation was found between exotropia and refractive status. The incidence of amblyopia was 33.1 % in esotropia and 19.7 % in exotropia. In accomodative esotropia, the patients with high AC/A ratio were treated with bifocal segment glasses. and the results were good.

OBJECTIVE: It has been reported that untreated sleep-disordered breathing (SDB) deteriorates over time, however this remains contentious. The aim of the present study is to evaluate the clinical course of SDB in middle-aged and older SDB patients, and to identify how relevant factors contribute to the change in SDB severity. METHODS: Baseline and follow-up polysomnographic data of 56 untreated SDB patients (mean age, 61.2±5.71) were obtained retrospectively and the mean interval was 62.4±22.0 months. Subgroup analysis was performed based on the baseline severity, and the factors associated with the course of SDB were analyzed. RESULTS: At the baseline, 13 subjects were simple snorers, 15 had mild to moderate SDB, and 28 were severe SDB patients. While there was no significant change in apnea-hypopnea index (AHI) as a whole, subgroup analysis showed decrease of AHI in severe SDB patients (43.9±10.6 to 35.6±20.0, p=0.009). The change in supine time percent and baseline AHI were associated with the change in AHI (β=0.387, p=0.003; β=-0.272, p=0.037). CONCLUSION: Untreated SDB did not deteriorate over time with modest improvement in severe SDB. A proportion of severe SDB patients might expect decrease in SDB severity irrespective of changes in sleep position or body weight.

The authors experienced a case of congenital dermoid cyst. It originated from the orbit, bulbar conjuntiva of both eyes and upper-lid of the left eye. This 6 years-old boy has a history of a progressively enlarging mass on both lateral canthus, bulbar conjunctiva and upper-lid of the left eye without pain and discomfort since birth. At the time of his first visit to our hospital, the lesion was 3 X 3 X 1.5cm (left eye) and 1.5 X 1.5 X 1cm (right eye) in size, yellowish-brown in color, firm and breast-like in shape. The vision was peor (right 0.1, left H.M.), the extraocular muscle motion was slightly limited. The roentgenographic and laboratory studies were in the normal limits. The surgical removal of the lesion was successfully performed under general anesthesia. The histopathological study revealed a dermoid cyst. After discharge, the patient was followed-up for 30 days. On lhe 15th postoperative day, epithelization was found. We found no evidence of further new growth.

BACKGROUND: Local anesthetics have been widely used to control postoperative pain and chronic pain. However, their usage in controlling long-lasting pain has been limited due to a relatively short duration of action. Many attempts have been made to develop a controlled release drug delivery system to provide long-lasting anesthesia. The goal of this study was to evaluate the histocompatibility and effectiveness of a new injectable lipid gel type drug delivery system (PHW, egg phosphatidylcholine/hyaluronic acid/water) using bupivacaine. METHODS: Eighty-four male Sprague-Dawley rats were divided into 3 groups; 44 in the bupivacaine group, 20 in the PHW-bupivacaine (PHW-B) group, and 20 in the PHW group; and each drug mixture was injected in a 0.1 ml solution near the sciatic notch. Motor block was assessed by direct observation of motor skills to splay toes. Sensory block was assessed by measuring withdrawal response latencies to radiant heat using an analgesiameter. Gross and microscopic examinations on the sciatic nerve and surrounding muscle were performed for 3weeks after the injection. RESULTS: Nerve block was significantly prolonged in the PHW-B group (190.0 +/- 42.8 min) compared to the plain bupivacaine group (99.0 +/- 30.5 min). There was no sign of nerve block in the PHW group. We observed moderate perimuscular inflammation in the PHW and PHW-B groups for the first 3 days. After 3 days, we did not observe inflammation of muscles and there was no sign of perineural inflammation. CONCLUSIONS: In conclusion, the histocompatibility of a bupivacaine incorporated PHW drug delivery system was satisfactory and the controlled releasing property of this drug delivery system was evaluated as effective.

Idiopathic gingival fibromatosis is associated with other abnorma ities of which the most striking is hypertrichosis of variable degree. Gorlin and Pindborg described this condition as a distinct syndrome termed idiopathic gingival fibromatosis and hypertrichosis. We report a case of idiopathic gingival fibromatosis and hypertrichosis occuring in 34-year-old woman with enlarged gingival tissue, hypertrichosis, and enlargenment of the breasts, ears and nose. Laboratory tests including hormonal and chromosomal studies were all within normal limits. Histologically, the gingival hyperplastic tissue showed thick bundle of collagen fibers with few fibroblasts or capillaries and little or no inflammatory infiltrate.
