Bezoyl peroxide, a powerful oxidizing agent, has been uaed topically in the treatment of acne vulgaris as a cream or lotion and has been shown to he effective for this codition. In 1972 Fulton emphaaized the importance of the vehicles used to obtain. maximum potential of benzoyl peroxide and for this, the gel formulation has been examined in many clinical trials. The present study was undertaken to evaluate the therapeutic effect of Fanoxyl 2.5, a 2.5% . benzayl peraxide gel, in patients with acne vulgaris. A total of 31 patients entered this study at the Departrnent of Dermatology, Jeoul National University Hospital rluring 3 rnanths period, from Decemher, 1978 through February, 1979, All patienta were instructed to apply Fanoxyl 2.5' on their affected areas once or twice a day and the nurnber of lesions on two or three t fixed areas were counted before and onee weekly after initation of the treatment. The reaults observed in the 3I patients were as follaws; 1. The percentage decrease in total nurnber of lesions in 4 weeks after treatment was 56.9%. 2. The authors could follow up for 6 weeks in 6 cases. In 6 case, the mean percentage in total number of lesions in 6 weeks after treatment was 81.7%. 3. Clesed and open eomedones were gradually eliminated; and their numbers were decreased in 4 weeks after treatment by 46.5% and 56.8% respeetiveIy. The papules were rapidly eliminated and their numbers were decreased in 4 weeka, after treatment by 79.8%. 4. Although most patients felt a mild burning sensation and tightness at the begining of the treatment, only a minority of the patients complained of discomfort due to pain(l case), erytherna(l case), tightness(2 cases),burning sensation (1 case), scaling(1 case). But all were tolerable without taking any specific measures or discontinuance of application. In one case, contact dermatitis developed after 4 weeks treatment. The authors concluded through this experiment that Panoxyl 2.5' (2.5% benzoyl peroxide gel) is a very effective local therapeutic agent in the treatment of acne vulgaris patients.

Unlike the case of adult obstructive sleep apnea syndrome (OSAS), there was no consistent finding on the changes of sleep architecture in childhood OSAS. Further understanding of the sleep electroencephalogram (EEG) should be needed. Non-linear analysis of EEG is particularly useful in giving us a new perspective and in understanding the brain system. The objective of the current study is to compare the sleep architecture and the scaling exponent (alpha) from detrended fluctuation analysis (DFA) on sleep EEG between OSAS and normal children. Fifteen normal children (8 boys/7 girls, 6.0+/-2.2 years old) and twelve OSAS children (10 boys/2 girls, 6.4+/-3.4 years old) were studied with polysomnography (PSG). Sleep-related variables and OSAS severity indices were obtained. Scaling exponent of DFA were calculated from the EEG channels (C3/A2, C4/A1, O1/A2, and O2/A1), and compared between normal and OSAS children. No difference in sleep architecture was found between OSAS and normal controls except stage 1 sleep (%) and REM sleep latency (min). Stage 1 sleep (%) was significantly higher and REM latency was longer in OSAS group (9.3+/-4.3%, 181.5+/-59.9 min) than in controls (5.6+/-2.8%, 133.5+/-42.0 min). Scaling exponent (alpha) showed that sleep EEG of OSAS children also followed the 'longrange temporal correlation' characteristics. Value of alpha increased as sleep stages increased from stage 1 to stage 4. Value of alpha from C3/A2, C4/A1, O1/A2, O2/A1 were significantly lower in OSAS than in control (1.36+/-0.05 vs. 1.41+/-0.04, 1.37+/-0.04 vs. 1.41+/-0.04, 1.37+/-0.05 vs. 1.41+/-0.05, and 1.36+/-0.07 vs. 1.41+/-0.05, p<0.05). Higher stage 1 sleep (%) in OSAS children was consistent finding with OSAS adults. Lower 'alpha' in OSAS children suggests decrease of self-organized criticality or the decreased piling-up energy of brain system during sleep in OSAS children.

OBJECTIVE: Spinal instrumentation without fusion often fails due to biological failure of intervertebral joints (spontaneous fusion, degeneration, etc). The purpose of this study is to investigate the influence of fixation rigidity on viability of intervertebral joints. METHODS: Twenty pigs in growing period were subjected to posterior segmental fixation. Twelve were fixed with a rigid fixation system(RF) while eight were fixed with a flexible unconstrained implant(FF). At the time of the surgery, a scoliosis was created to monitor fixation adequacy. The pigs were subjected to periodic radiological examinations and 12pigs (six in RF, six in FF) were euthanized at 12-18months postoperatively for analysis. RESULTS: The initial scoliotic curve was reduced from 31+/-5degrees to 27+/-8degrees in RF group (p=0.37) and from 19+/-4degrees to 17+/-5degrees in FF group (p=0.21). Although severe disc degeneration and spontaneous fusion of facet joints were observed in RF group, disc heights of FF group were well maintained without major signs of degeneration. CONCLUSION: The viability of the intervertebral joints depends on motion spinal fixation. Systems allowing intervertebral micromotion may preserve the viability of intervertebral discs and the facet joint articular cartilages while maintaining a reasonably stable fixation.

Cloeortolone (9-a-chloro-6-a fluoro-11-B 21 digydroxy-16 methyl preganl,4-diene) is a newly synthesized corticonsteroid which has been found to have potent antinflammatory action and good tolerance through animal experiment. Several investigators reported its therapeutic affect in various dermatoses by topical application. The present was undertaken to evaluate the therapeutic effect of 0.1% clocortolone cream (Purantix-Sandoz) in patients with eczematous dermatoses and with psoriasis and to compare its effect with that of I% hydrocortisone. Eleven patients with contact dermatitis, 10 with psoriasis entered this study durtin the period of 6 months from January to june, 1977 at the Department of Dermatology, Seoul National University Hospital. All patients were instructed to apply 0.1% Clocortolone cream on one side of their lesion and 1%hydrocortisone cream on the opposite site for two weeks. After wo weeks' period of observation the status of the lesion was evaluated clinically and the tesults were as follows. 1. Ninety one percent of patiens with contact dermatitis, 70% of atopic dermatitis, 60% of nenrodermatitis, 67% of nummular eczema and 60% of psoriasis responded very effectively or moderately effectively. The therapeutic responses were generally similar to that of 1% hydrocortisone. 2. During the ovservation period, there was no systemic of local side effect of 0.1% Clocortolone cream.

BACKGROUND: This study investigated the efficacy and safety of combined subacromial and intravenous patient-controlled analgesia for control of postoperative pain after arthroscopic rotator cuff repair. METHODS: Between May 2012 and August 2014, 60 patients who underwent arthroscopic rotator cuff repair with acromioplasty and received patient-controlled analgesia were studied prospectively. Cases were divided into 2 groups: combined subacromial and intravenous infusion group (group A, 30 cases) and solitary intravenous infusion group (group B, 30 cases). The visual analogue scale was used to record the patient's level of pain every 12 hours during postoperative 72 hours and the following 48 hours after the suspension of patient-controlled analgesia. RESULTS: The mean preoperative visual analogue scale score was 7.8 in group A and 7.6 in group B, and the immediate postoperative visual analogue scale score was 7.9 and 8.1 for each group. At postoperative time (From 12 hours to 72 hours after operation), the scores of combined subacromial and intravenous infusion were significantly lower than those of solitary intravenous infusion. Significant difference in the frequency of supplemental analgesic injections was observed between group A and group B (p=0.008). However, no significant difference in complication rate was observed between the two groups (p=0.562). CONCLUSIONS: Combined subacromial and intravenous patient-controlled analgesia after arthroscopic rotator cuff repair is more effective than solitary intravenous infusion without significantly increasing complications. Therefore, combined subacromial and intravenous patient-controlled analgesia could be a effective pain control method.
