Subperiosteal Cortical Defect is a symptomless rarefaction of cortical bone which begins most often on the external surface of the medial and posterior cortical walls of the lower end of the femur in children between the ages of 3 and 6 years. The name of Subperiosteal Cortical Defect was first used by Aegerter who differentiated it from non-osteogenic fibroma. The authors found out 5 positive cases of incidental findings among 62 cases of both knee joint X-ray of which 3 was male and 2 was female. Also we experienced 3 cases which necessiat d a correct diagnosis and differential diagnosis. Because this is a common lesion, it frequently accompanies more serious bone conditions, and because this is self-limited disease, treatment is not necessary. It was emphasized that its nature should be understood by all those dealing with bone disease lest it be overdiagnosed and overtreated.

PURPOSE: It is to report the efficacy and safety of an argon laser photocoagulation which was the treatment modality for retinopathy of prematurity. METHODS: From March 1996 to December 1999, on 69 prethreshold retinopathy of prematurity, they were series of observations following periods of two to five days, one week, two weeks, four weeks, three months and one year time respectively. RESULTS: We noticed the regressions in 84 prethreshold retinopathy of prematurity cases as well. CONCLUSIONS: The report emphasized the advantages of the argon laser photocoagulation which reduce the risk from a general anesthesia by applying a topical anesthesia, and the safety of using laser technique of convenience to apply and minimize the tissue damages of the lesions. It also described the preferable consequent results following the early treatment with divided applications on the prethreshold cases.

PURPOSE: To compare the results of laser epithelial keratomileusis (LASEK) and epi-laser in situ keratomileusis (Epi-LASIK) for the treatment of moderate to high myopia. METHODS: In this study, 50 patients with a manifest refraction of moderate to high myopia were assigned to two groups: 50 eyes of 25 patients treated with LASEK and 50 eyes of 25 patients treated with epi-LASIK. Uncorrected visual acuity (UCVA), manifest refraction, corneal haze, and postoperative pain were reviewed in LASEK and epi-LASIK treated eyes at 3 months after the operation. RESULTS: At one week after surgery, UCVA was recovered more rapidly after epi-LASIK than LASEK (LASEK: 0.61+/-0.23, Epi-LASIK: 0.79+/-0.11, p<0.05), but UCVA at both 1 and 3 months showed no significant difference between the LASEK and epi-LASIK groups. However, epi-LASIK-treated eyes had lower postoperative pain scores and lower corneal haze scores (1 month; p=0.01) than those of LASEK-treated eyes. CONCLUSIONS: Epi-LASIK showed a more rapid visual recovery than LASEK at 1 week after surgery for the correction of myopia. Epi-LASIK-treated eyes also had less postoperative pain and an earlier reduction of postoperative corneal haze. These results suggest epi-LASIK could be a viable alternative procedure for the correction of moderate to high myopia.

Cerebral cavernous malformation with giant cysts is rare and literature descriptions of its clinical features are few. In this case study, the authors describe the clinical symptoms, radiological findings, and pathological diagnosis of cerebral cavernous malformations with giant cysts, reviewing the relevant literature to clearly differentiate this from other disease entities. The authors present a case of a 19-year-old male with a giant cystic cavernous malformation, who was referred to the division of neurosurgery due to right sided motor weakness (grade II/II). Imaging revealed a large homogenous cystic mass, 7.2x4.6x6 cm in size, in the left fronto-parietal lobe and basal ganglia. The mass had an intra-cystic lesion, abutting the basal portion of the mass. The initial diagnosis considered this mass a glioma or infection. A left frontal craniotomy was performed, followed by a transcortical approach to resect the mass. Total removal was accomplished without post-operative complications. An open biopsy and a histopathological exam diagnosed the mass as a giant cystic cavernous malformation. Imaging appearances of giant cavernous malformations may vary. The clinical features, radiological features, and management of giant cavernous malformations are described based on pertinent literature review.

BACKGROUND: Contact dermatitis is frequently caused by cosmetics. Detection of causative allergens is important in prevention and treatment of cosmetic contact dermatitis. Patch test has been accepted as the only reliable diagnostic method to detect allergens. OBJECTIVE: The objectives of this study were to clarify evoluting trends of positive patch tests and to compare the positive frequencies of various allergens between different time sequences. MATERIALS AND METHODS: We reviewed patch test results of the 806 cosmetic contact dermatitis patients, who had visited our clinic from 1982 to 1997. We divided the patients into three groups as follows: I group:1982-1987, II group:1988-1992, III group:1993-1997 and compared the test results. The patch tests were performed with standard batteries, cosmetic-related allergens and the patients's own cosmetics. RESULTS: The results of the studies were summarized as follows; 1. Trends of increasing positivity in cosmetic-induced dermatitis was noted in a chronologic point of view. Among the patients, an increased proportion of males was notable. 2. In age distribution, a decreasing proportion of patients at the third & the fourth decades was observed. Contrary to this, the proportion of patients over the fifth decades was increased. 3. Among standard allergens, nickel sulphate showed the highest positive rate in all defined triple periods, whereas positive rates of neomycin sulphate & balsam of Peru were diminishing sequentially. Among fragrance allergens, cinnamic alcohol & cinnamic aldehyde revealed the highest positive rates. 4. In as is test, skin care products showed the highest positive rate, followed by toiletries and makeup products. Increasing positive rates of the toiletry products were observed in order of time. In fragrance products, positive rates reached their peak in the second period and declined in the third period. CONCLUSION: This study showed that perfume components were the most frequent allergens in cosmetics followed by preservative agents. Our study showed that comestic allergies in men seems to have increased.

Combining benzodiazepine with opioid has been used for analgesia and sedation during spinal anesthesia, but many authors have warned that combined administration of these drugs produces potent drug interaction that places patients at high risk for hypoxemia and apnea. This study was undertaken to observe the effect of combined use of diazepam with fentanyl on hemodynamic response and change in SaO in twenty healthy adult patients undergone elective surgery with spinal anesthesia. All of the patients were divided into the control and experimental group, and whom spinal anesthesia with 0.5% tetracaine the 12 mg and epinephrine 0.2 mg, were performed. To the control(Group I) and experimental group(Group 2) the combined dose of diazepam 0. 075 mg/kg with fentanyl 1 ug/kg, and diazepam 0.15 mg/kg with fentanyl 2 ug/kg, were given, respectively, by intravenous injection 1 hour after spinal anesthesia started. Blood pressure, heart rate and SaO2 of the two groups were compared at the time before administration of study drugs and 1 min, 2 min, 2 min, 4 min, 5 min, 10 min, 30 min and 60 min after administration of study drugs. The results were as follows. 1) SaO2 was significantly decreased in group 2 than Group 1 after study drugs were administed intravenously. 2) In both group, decrease in SaO2 was significant at the first 5 minutes after intravenous administration of study drugs. 3) SaO2 fell to 90% of the control value after the administration of study drugs in 6 patients of Group 2(60%). 4) Hemodynamic changes after intravenous administration of study drugs were statistically significant but not so clinically in both group. We concluded that combined intravenous administration of benzodiazepine and opioid under spinal anesthesia requires the careful monitoring of hemodynamic response and ventilatory status continuosly with those monitoring devices already in use and pulse oximeter. Availiability of skilled anesthesiologists for airway management and administration of supplemental oxygen are very important in combined intravenous administration of benzodiazepine and opioid.

One to three percent of childhood brain tumors are choroid plexus tumors. Of these, 30-40% are considered to be choroid plexus carcinoma. We report one case of choroid plexus carcinoma without parenchymal invasion, which showed rapid dissemination along whole CSF pathway and developed postoperative hydrocephalus in spite of gross total resection.

We compare the safety and efficacy of locked and non-locked plating systems with retrospective review of 51 consecutive acute cervical injury patients who underwent anterior cervical plating procedures. The two groups were comparable in demographic details, mean age(locked 40.8, non-locked 37.9), average fusion level(locked 1.53, non-locked 1.67) and fusion rate(locked 100%, non-locked 86.7%). Hardware related complication in locked plate group was seen in one patient(2.78%), but did not required the reoperation. In the non-locked plate group, 4 patients developed screw loosening and, in 1 patient, the inferior screw was found to be 2mm posterior to posterior cortex. Reoperation was needed for this case due to symptomatic myelopathy. In the non-locked plate group instrument related reoperations was done in 5 patients(33.4%) and longer operation time was required than locked system. In this study, anterior cervical fusion with plating was nessessory for stabilizing of acute cervical instability and improving neurological outcome and fusion rate. For this purpose, locked system was theoratically safter and technically easier than non-locked system.
