This study was undertaken to investigate the recovery of epidermal Langerhans cells in relation to time after UVA irradiation through different amounts and ways of exposure in CH mice. We irradiated the ears of C2H mice with UVA 200J/cm2 and 400J/cm2 in a single dose at one time or 5 fractionated doses for 5 days and performed biopsies on the ears of the control and experimental groups after 2, 7, 14, 21days of irradiation and stained them with immunoperoxidase method. The results are summarized as follows, l. We observed a significant decrease in the number of the Ia-positive epidermal Langerhans cells in the single-dose-exposed group compared to the fractionated- dose-exposed group on 7th and 14th days irradiated with UVA 200J/cm. 2. There was no significant difference in the change in the number of the Ia- positive epidermal Langerhans cells until 21 days of exposure between the single- dose-exposed group and the fractionated-dose-exposed group irradiated with UVA 400 J/cm 3. In the group irradiated with UVA 2003/cm, the reduced number of the Ia-positive epidermal Langerhans cells returned to normal on the 14th day after irradiation in the fractionated-dose-exposed group and on the 21st day in the single- dose-exposed group. In the group irradiated with 400J/cm, the number returned to normal on the 21st day of irradition both in the fractionated-dose-exposed group and in the single-dose-exposed group.

Spinal instrumentation using pedicle screws offers several advantages such as 1) achievement of rigid fixation through the pedicles which is the strongest structure of spine, 2) nearly anatomic reduction by direct force on the deformed sites of fracture and 3) preservation of mobile segments by short segment fixation. The authors analysed 14 cases of unstable thoracolumbar and lumbar fracture treated by pedicle screw fixation from May 1988 to June 1989. Mean follow up was 14 months(8M.-20M.) and following results were obtained. 1. Most of the cases were male(13 cases) and their age ranged from 26 to 55 with an average of 36. 2. According to Denis classification, there were 7 cases of burst fracture, 5 cases of fracture-dislocation, 1 case of seat belt injury and unclassified one case. 3. After operation, the height of anterior column was reduced from 61% to 86%, posterior column, from 134% to 105%, local kyphosis, from 17.4% degrees to 3.4 degrees and anterior translation, from 6mm to 1.2mm. 4. In comparision of preoperative and postoperative moter index between fracture-dislocation and burst fracture, the former changed from 3.2 to 21.8 and the latter, from 40.2 to 48.6. 5. Significant neurologic recoveries were observed in all cases except one complete paraplegia. 6. There was no significant complication and minimal loss of correction was noted.

A clinical study was carried out on patients with tuberculous meningitis who were admitted to the Department of Pediatrics, Kwangju Christian Hospital during a 9 year period from January, 1971 to December, 1979. The following results were obtained. 1) About 3/4 of all cases were under the age of 6, the majority being between the age of one and three. The male-to-female ratio was 1.3:1. 2) Seasonal incidence was in the order of spring, summer, winter and autumn, but no sign ificant differences were noted. 3) A family history of tuberculosis was found in 41.5%, usually in one of the parents. 4) A history of B.C.G. vaccination was found in 16.7% of tuberculous meningitis cases. The tuberculin test was positive in 28.9%. 5) The most frequent symptoms on admission were vomiting, fever, convulsion and headache, in that order. 6) The major neurologic findings were unconsciousness(34.0%), neck stiffness(76.4%), and positive Kernig's sign(63.2%). 7) Leukocytes in the C.S.F. on admission were generally elevated, but below the range of 500/mm3 in 74.5% of cases, and the mean count was 278.7/mm3 with 66.7% lymphocytes. Mean protein level in the C.S.F. was 162.5mg/dl, and 94.3% of all cases were over 50mg/dl. Sugar in the C.S.F. was definitely reduced to less than 120 mEq/L in 78.3%, with the mean level being 112.8mEq/L. 8) Chest X-ray revealed tuberculous lesions in 69.8% and miliary tuberculosis was found in 36.8% of cases. 9) The highest mortality was seen in young infants. Among 26 patients of clinical stage I on admission, 21(80.3%) recovered, and 35(79.5%) of 44 patients of stage II recovered, whereas only 13(36.1%) out of 36 patients of stage III were cured. Over-all mortality rate was 5.7% of those followed.

Abdominal wall hematoma is a rare but well-known disease, usually caused by trauma or, on rare occasions, occurring spontaneously. Hematomas of the rectus sheath and the anterolateral abdominal wall are commonly associated with injury to the inferior epigastric artery and the deep circumflex iliac artery, respectively. The diagnosis of spontaneously developed abdominal wall hematoma is sometimes delayed, due its clinical manifestations being similar to those of other causes of the acute abdomen. CT and angiography can be helpful in the diagnosis of the hematoma and the injured vessel. Herein, we report on a rare case of a spontaneously developed anterolateral abdominal wall hematoma treated with microcoil embolization of the left deep circumflex iliac artery.

Rosai-Dorfman disease (RDD) is an idiopathic histioproliferative disorder of the lymph nodes and extranodal sites. Central nervous system involvement is extremely rare. Intracranial RDD, especially the isolated form, resembles meninigioma both clinically and radiologically. Here, we report a case of isolated, intracranial, dura-based RDD. The patient presented with headache and dizziness with no evidence of lymphadenopathy. Histologically, the lesion consisted of large histiocytes with emperipolesis and lymphoplasma cell infiltrates with a fibrotic background. We discuss the differential diagnosis of this lesion. To our knowledge, this is the first reported Korean case of intracranial RDD.

PURPOSE: To investigate the clinical features of Korean patients with congenital aniridia. METHODS: This retrospective study focused on 60 eyes from 31 patients who were diagnosed with congenital aniridia at Kangnam St. Mary's Hospital from 1996 to 2007. Patient age, gender, visual acuity (VA), family history, and previous ocular history were recorded. The presence of keratopathy, glaucoma, cataract, foveal hypoplasia, and other ocular or systemic anomalies were evaluated for each patient. RESULTS: The proportion of sporadic cases was 29.0%. Cataract (82.5%), glaucoma (51.6%), keratopathy (71.6%), and foveal hypoplasia (81.8%) commonly accompanied aniridia. Thirty-four (60.7%) eyes had VAs less than 20/200 and 20 eyes (35.7%) had VAs between 20/200 and 20/60. In patients without a past history of ocular surgery, the mean central corneal thickness was 643.05 +/- 37.67 microm and the mean endothelial cell count was 3,349.44 +/- 408.17 cells/mm2. Ocular surface surgeries were performed in 6 eyes. The clarity of the transplanted corneal graft vanished in 5 eyes with the progression of peripheral neovascularization and subepithelial fibrosis. The mean age of cataract surgery in 8 eyes was 29.8 +/- 5.9 years. Postoperative worsening of corneal clouding and glaucomatous damage were observed in 4 eyes. Two infants had bilateral congenital glaucoma. Two children with sporadic aniridia were identified to have Wilm's tumors. CONCLUSIONS: Congenital aniridia is a progressive congenital disorder that is commonly accompanied by complications that can lead to impaired vision. Regular, careful examinations for these accompanying complications should be performed in all patients with congenital aniridia.

OBJECTIVE: Korea Institute of Drug Safety and Risk Management works for signal detection and safety information generation by analyzing spontaneous adverse event reports database. As the number of reports and detected signals of aripiprazole by each data mining indices were more than other drugs, aripiprazole was selected as a subject of study. METHODS: 1989-2012 spontaneous reporting database was analyzed and the model drug ingredient was aripiprazole. We estimated proportional reporting ratio, reporting odds ratio, and information component for data mining. Then we assessed the causality through review of local and foreign drug labels and literatures. RESULTS: In reconstructed 1989-2012 spontaneous reporting database, there were 2,062 reports on aripiprazole and 2,565 aripiprazole-adverse events pairs. As a result of data mining analysis and signal prioritization, 78 adverse events were detected, 20 adverse events of them were not included in drug label. After literature review, back pain, epistaxis, xerophthalmia and ejaculation disorder were generated as novel safety information on aripiprazole. CONCLUSION: Those 4 novel safety informations of Aripiprazole, back pain, epistaxis, xerophthalmia and ejaculation disorder had become listed on the local label in April 2013.
