BACKGROUND: The study aimed to determine the type of capsular insertion and the extent of capsular elongation in anterior shoulder instability by quantitatively evaluating their computed tomography arthrographic (CTA) findings, and to investigate the correlation of these parameters with surgical outcomes. METHODS: We retrospectively reviewed 71 patients who underwent CTA and arthroscopic capsulolabral reconstruction for anterior shoulder instability between April 2004 and August 2008. The control group comprised 72 patients diagnosed as isolated type II superior labrum anterior to posterior (SLAP) lesion during the period. Among the 143 patients, 71 were examined with follow-up CTA at an average 13.8 months after surgery. It was measured the capsular length and cross-sectional area at two distinct capsular regions: the 4 and 5 o'clock position of the capsule. RESULTS: With regards to the incidence of the type of anterior capsular insertion, type I was more common in the control group, whereas type III more common than in the instability group. Anterior capsular length and cross-sectional area were significantly greater in the instability group than in the control group. Among patients of the instability group, the number of dislocations and the presence of anterior labroligamentous periosteal sleeve avulsion lesion were significantly associated with anterior capsular redundancy. Postoperatively, recurrence was found in 3 patients (4.2%) and their postoperative capsular length and cross-sectional area were greater than those of patients without recurrence. CONCLUSIONS: Capsular insertion type and capsular redundancy derived through CTA may serve as important parameters for the management of anterior shoulder instability.

Aflatoxin B1 (AFB1), a fungal toxin produced by Aspergillus flavus, is known to be a possible hepatocarcinogen. But the molecular biologic changes which may occur following exposure to AFB1 are not known and thus the carcinogenesis is not yet understood. This study was performed to examine the expressions of c-myc, c-fos and TGF-alpha genes and to investigate the possible role of those molecular biologic changes in hepatic regeneration and in the development of hepatocellular carcinoma (HCC). Sprague-Dawley rats were divided into 3 groups: Carbon tetrachloride (CCl4) only was administered to group I, AFB1 only was administered to group II and a combination of AFB1 and CCl4 was administered to group III. The animals were sacrificed at 0.5, 1, 2, 6, 12, 24, 48, and 72 hours after treatment. In addition to the examination of the hematoxylin-eosin stained sections, hepatic regeneration and apoptosis were analyzed quantitatively by bromodeoxyuridine (BrdU)-anti-BrdU immunohistochemistry and TUNEL assay utilizing apoptosis kit, respectively. The hepatic expressions of c-myc, c-fos and transforming growth factor-alpha (TGF-alpha) were examined by immunohistochemistry and studied by Western blot. The number of BrdU labelled cells and the degree of necrosis/apoptosis were comparable among the different groups. Livers of the group II rats showed nearly normal histology without regeneration and necrosis/apoptosis. In groups I and III, the number of BrdU- labelled cells showed an increase at 48 hours after treatment, and the increment was significantly higher in group I than in group III. Most BrdU-labelled cells were mature hepatocytes in group I, whereas in group III they appeared to be less mature. In group I, apoptosis showed an increase at around 24 hours, but appeared in group III as early as 12 hours after treatment and persisted through 48 hours. The expression of c-myc and c-fos were also different between the experimental groups. The expression intensity of c-myc in group I was highest at 1 hour and decreased thereafter. In groups II and III, the expressions were much more intense than in group I, except at 1 hour, and the increased intensity persisted throughout the experiment. Group II in particular showed a peak intensity at 30 minutes and at 6 hours after treatment. In group I, c-fos was strongly expressed only at 24 hours, but in group III, there was progressively increased expression with peak intensity at 24 hours. TGF-alpha was expressed in similar intensities in all groups throughout the experiment. These results suggest that AFB1 may evoke an intense and protracted expression of c-myc, provocating the CCl4-induced necrosis of hepatocytes, and a prolonged expression of c-fos, including persistent signals for regeneration which in turn may activate the replication of immature cells. These findings will aid further investigation of molecular biologic and histologic characteristics of the hepatotoxic and hepatocarcinogenic mechanism of AFB1 in rats. And these results in rats, together with clinico-epidemiologic and molecular biologic investigations in humans and other animals, suggest that AFB1 may supply hepatocarcinogenic background in early exposure time in AFB1-contaminated areas of China and Korea.

Sertoli-Leydig cell tumor or Brenner tumor is a relatively rare ovarian tumor. Other associated elements in the form of epithelial, mesenchymal, and tumor components of each tumor have been reported. The Sertoli-Leydig cell tumor with a Brenner tumor element has not been documented in the literature, so we are reporting on a case of Sertoli-Leydig cell tumor coexisting with a Brenner tumor. This 62-year-old woman presented with a 4 year history of lower abdominal mass and vaginal bleeding. Exploratory laparotomy was done. The left ovary showed a multiseptated, cystic, yellow-white solid mass, measuring 17.0x13.0x5.0 cm and weighing 985.0 gm. Microscopic examination revealed a tubular or trabecular arrangement of the Sertoli cells and variable numbers of Leydig cells. There were several tumor nests with cystic spaces composed of ovoid cells showing longitudinal nuclear grooving. Sarcomatoid or heterologous elements were not found.

Penetrating autokeratoplasty for optical has seldom been reported in recent literature. The patien presented here is a male, aged 31, farmer, who had a dense extensive corneal scar in his right eye. Keratoplasty, 6.5mm in disc diameter. 8 edge-to-edge direct sutures, postoperative beta-radiation, had been performed eventlessly on July 15. 1964 and postoperative reaction was minimum. The visual acuity improved from counting finger 30cm to 0.1 of Landolt's broken ring chart after 4 months of follow up observation. Minimum postoperative complication makes authors postulate autoplasty is relatively safe procedure.

PURPOSE: The purpose of this study was to estimate the effects of an infection control program on the Clonorchis sinensis (CS) infection ratio, CS-related knowledge and health behavior of people living near the Geum River. METHOD: A one-group pretest-posttest design was used with 102 participants. For 12 months the participants were provided with promotion announcements, health education, counseling, and medication. Outcome variables measured were the CS infection ratio by stool examination, CS-related knowledge and health behavior from self-report questionnaires. The pre intervention data were collected from January to February 2008 and the post intervention data during the same period in 2009. Collected data were analyzed using descriptive statistics, generalized estimating equation analysis, and paired t-test with SPSS for Windows version 15.0. RESULTS: In the pre test 21 of the 102 participants showed infection with CS for the first time. In the post test 9 were newly infected with CS, and one was re-infected. The CS-related knowledge was significantly improved after the infection control program (p<0.05). The CS-related health behaviors did not improve. CONCLUSION: These results showed that an infection control program is effective in decreasing CS infection ratio and improving CS-related knowledge of people living near the river.

A survey was conducted by the staff of the College of Medicine and School of Public Health, Seoul National University in cooperation with Seoul Special City from 1 December 1967 through 28 February 1968, on such events as delivery, death, abortion and pregnancy. The survey directed to a total population of 47,811 residing in 9,157 households led us to the following findings: 1. Two year averages of crude birth rate, crude death rate and natural increase rate were 30.1, 5.6 and 24.5, respectively. 2. Of all deliveries, home and hospital deliveries constituted 61.1 per cent and 35.5 per cent, respectively. 3. Deliveries other than hospital deliveries were found to be attended more often by mother-in-laws(26.5 per cent) than by doctors or midwives(23.4 per cent). 4. About 52 per cent of all women having experiences in pregnancy during the last two years had an experience of consulting a doctor at least one time throughout whole period of pregnancy. 5. In most cases scissors were used to cut umbilical cords, of which 71.0 per cent were not sterilized and only 28.3 per cent sterilized. 6. In many cases placenta was incinerated(48,2 per cent) and on many other occasions it was thrown away into water(28.3 per cent). 7. Cement page(37.4 per cent), gauze and absorbent cotton(29.8 per cent)were found to be most frequently used to receive new-born babies. 8. In 1966 8.8 per cent of the women had at least one abortion induced and in 1967 the percentage was 9.2 per cent. 9. Nearly all(95.8 per cent) of the induced abortions reportedly were done at doctor's clinics. 10. Of all the abortions induced 65.3 per cent were done by specialists in obstetrics, 30.3 per cent by general practitioners and 2.7 per cent by midwives. 11. Those who experienced spontaneous abortions were 1.9 per cent of all women both in 1966 and 1967. 12. About 9.2 per cent of women investigated were found to be currently pregnant. 13. Age specific death rate turned out to be highest among those under 1 year of age. 14. Ten major causes of death in their order of frequency were: 15. Places of death can be classified into homes(75.3 per cent) and hospitals(13.2 per cent). 16. Method of disposing of corpses comprised burials(54.2 per cent) and cremations(44.6 per cent). 17. Infant, neonatal and hebdomadal mortality rates have been computed at 32.2, 18.9 and 13.7, respectively. 18. Infants were found to have died either at homes(81.5 per cent) or at hospitals(18.5 per cent). 19. Birth registrations had been done for about 18.5 per cent of the dead infants.

Purpose: To document the distribution and clinical features of iridocorneal endothelial (ICE) syndrome in its various subtypes observed in patients who visited a single institution in Korea. Methods: A retrospective analysis was conducted on the medical records of patients diagnosed with ICE syndrome at the Department of Ophthalmology, Yeungnam University Hospital, from 1993 to 2023. The cases were classified into Chandler syndrome, progressive iris atrophy, and iris nevus syndrome based on the severity of corneal and iris abnormalities. We also examined the presence of glaucoma, corneal edema, and iris abnormalities at diagnosis. Results: In all, 22 eyes from 21 patients with ICE syndrome were included. The mean age at diagnosis was 56.6 ± 16.1 years with a female predominance (20 patients, 95.5%). The syndrome was primarily unilateral (20 patients, 95.5%). Subtypes included 9 eyes with Chandler syndrome (40.9%), 7 eyes with progressive iris atrophy (31.8%), and 6 eyes with iris nevus syndrome (27.3%). Glaucoma was present in 15 eyes (68.2%), with 8 eyes (36.4%) undergoing glaucoma surgery. Of the 7 eyes that had trabeculectomy as initial glaucoma surgery, six experienced poor intraocular pressure control leading to Ahmed valve implantation in 4 cases. Corneal edema was noted in 10 eyes (45.5%) at diagnosis progressing to corneal decompensation in 6 eyes (27.3%). Conclusions ICE syndrome in Korea predominantly affects middle-aged women and occurs unilaterally with Chandler syndrome being the most common subtype. Given the high risk for glaucoma development, suboptimal outcomes of trabeculectomy, and significant risk for corneal decompensation, ongoing management efforts are essential for glaucoma and corneal function preservation.
