The clinical and pathological features of trichoadenoma are presented. Trichoadenoma is very rare, and as far as we know, no report on the trichoadenoma has been published in korea literature. We experienced a case of trichoadenoma occured in a 29 year-old male, who had a 0.9x0.7x0.4cm sized and slowly growing mass in the right buttock. The histopathological findings and histogenesis of trichoadenoma were discussed and a brief review of the literature was made.

BACKGROUND: In the most of emergency department, the diagnosis of appendicitis has been carried by clinical history, physical examination and plain X-ray. But the diagnostic accuracy by these methods was so low that unnecessary operation was common performed, and sometimes the operation was delayed till the physicians could confirm the acute appendicitis clinically. Although many kinds of diagnostic tools such as CT scan, laparoscope, and etc, we believe that ultrasonography(US) would be a quick and sensitive diagnostic method for the evaluation of acute appendicitis in the Emergency Department. METHODS: Forty-seven patients who were clinically suspected as acute appendicitis were evaluated with the grayscaled US by emergency physician. The probe of US was placed on maximal tender point of abdomen, and the appendix image was evaluated while probe was pressed deeply and gentry. When the blind loop was fecund at maximal tender point of abdomen, we evaluated the diameter of appendix, the presence of compressibility, peri-aspen-diceal fluid collection and other mass effect. As soon as the ultrasonographic evidences of the appendicitis were noticed, the operations were done and pathologic report were reviewed later. RESULTS: Among the forty-seven patients, forty patients were diagnosed as a appendicitis by US, and most common ultrasonic findings were as follows; 1) non-compressible blind loop larger than 5 mm in diameter, 2) wall thickening more than 3 mm, 3) peri-appendiceal fluid collection, 4) periappendiceal mass. Among remaining 7 patients in whom we could not get any positive findings of appendicitis, abdominal CT scan was carried in 2 cases who had direct and rebound tenderness on right lower abdomen, and CT scan showed the evidences of the appendicitis. The other 5 cases without rebound tenderness were observed far 2 hours, and abdominal pain was disappeared lately. Finally forty-two patients were operated and confirmed as acute appendicitis by pathologic reports; 24 were reported as suppurative appendicitis, and 12 cases of gangrenous appendicitis, 3 cases of perforated appendicitis, and 3 cases were peri-appendiceal abscess. The specificity of US in the diagnosis of acute appendicitis was 71.4%, and the sensitivity was 95.2%. CONCLUSIONS : In some patients suspected appendicitis, emergency physicians could diagnosis acute appendicitis accurately and rapidly by use of ultrasonography. Although the US was an actuate imaging modality to diagnosis acute appendicitis and evaluate its complications, we recommend a laparotomy or abdominal Cf scan in the patients with negative US findings in spite of presence of peritoneal irritation signs such as rebound tenderness and/or muscle guarding on right lower abdomen.

Sebaceous epithelioma is a relatively rare tumor, mostly occuring in the face or scalp. The histogenesis and clinical and pathological features of sebaceous epithelioma have not been clearly defined, and a few other diagnostic terms have been used so far instead of sebaceous epithelioma. Two cases of sebacous epitheliomas were presented. No recurrence or metastasis was observed in our cases, so sebaceous epithelioma is considered to be a benign tumor. A brief review of the literature, concerned about the biological behavior, histogenesis and pathological findings of the sebaceous epithelioma, was made.

PURPOSE: The purpose of this study was to develop an integrated internet addiction prevention program and test its effects on the self-regulation and internet addiction of elementary students who are at risk for internet addiction. METHODS: A quasi-experimental study with a nonequivalent control group pretest-posttest design was used. Participants were assigned to the experimental group (n=28) or control group (n=28). Contents of the program developed in this study included provision of information about internet addiction, interventions for empowerment and methods of behavioral modification. A pre-test and two post-tests were done to identify the effects of the program and their continuity. Effects were testified using Repeated measures ANOVA, simple effect analysis, and Time Contrast. RESULTS: The self-regulation of the experimental group after the program was significantly higher than the control group. The score for internet addiction self-diagnosis and the internet use time in the experimental group were significantly lower than the control group. CONCLUSION: The effects of the integrated internet addiction prevention program for preventing internet addiction in elementary students at risk for internet addiction were validated.

PURPOSE: To report the surgical results of unilateral pediatric cataracts from uncertain causes in relatively older children and to identify factors related to better visual outcomes. METHODS: We retrospectively evaluated the medical records of 39 patients who underwent surgery between the ages of 3 and 10 years for unilateral pediatric cataracts of no known cause. All patients underwent primary intraocular lens implantation and postoperative amblyopia treatment. A postoperative final visual acuity better than 20 / 30 was considered to be a good visual outcome. RESULTS: The mean age of patients was 6.0 ± 1.8 years at the time of surgery. The mean preoperative visual acuity was 1.07 ± 0.71 logarithm of the minimum angle of resolution (range, 0.15 to 3.00), while the mean final postoperative visual acuity was 0.47 ± 0.54 logarithm of the minimum angle of resolution (range, 0.00 to 2.00). Of 39 patients, 18 (46.2%) achieved a good visual outcome. Only the preoperative visual acuity maintained a significant association with a good visual outcome according to our multivariate analysis (p = 0.040). A preoperative visual acuity of 20 / 100 or better was found to increase the chance of achieving a good visual outcome by 13.79-fold (95% confidence interval, 1.13 to 167.58). CONCLUSIONS: The visual outcome of unilateral pediatric cataract surgery for cataracts with no specific cause identified in patients after three years of age could be satisfactory, especially with a preoperative visual acuity of 20 / 100 or better.

Tracheal bronchus is an aberrant bronchus that arises most often from the right tracheal wall above the carina and is the result of an additional tracheal outgrowth early in embryonic life. It; incidence ranges between 0.1 and 5%. This anomaly is usually diagnosed incidentally during bronchoscopy, bronchography or computed tomography. Occasionally, it represents the underlying etiology for chronic pulmonary disease, especially if it involves the right upper lobe and reflects an abnorrnal pulmonary clearing mechanism. The tracheal bronchus may be associated with other bronchopulmonary anomalies, tracheal stenosis, or Down's syndrome. Asymptornatic tracheal bronchus does not require any treatment. In case of tracheal bronchus associated recurrent right upper lobe diseases, tracheal bronchus therapy should include resection of the aberrant bronchus as well as the lob it supplies.

The prolonged use of steroids, especially the topical administration of ccrticosteroid, will causes an intraocular pressure(IOP) devation in some patients with clinical finding that typically resemble primary open-angle glaucoma. The authors experienced a case of steroid-induced glaucoma following systemic and topical use of dexamethasone for seborrheic dermatitis of both eyelids 3 years previously. During the past few months patient had noted complete lloss of vision in right eye and decrease of vision considerably, in left eye and a trabeculectomy was done on the left eye. We report a case of steroid-induced glaucoma and the literatures were reviewed briefly.

OBJECTIVE: To test if the intake of H2 receptor antagonists (H2-RAs) increases the risk of gastric cancer in the elderly. METHODS: The source population for this study was drawn from the responders to a questionnaire survey administered to the Korea Elderly Pharmacoepidemiological Cohort (KEPEC), who were beneficiaries of the Korean Medical Insurance Corporation, were at least 65 years old, and residing in Busan in 1993. The information on H2-RAs exposure was obtained from a drug prescription database compiled between Jan. 1993 and Dec. 1994. The cases consisted of 76 gastric cancer patients, as confirmed from the KMIC claims data, the National Cancer Registry and the Busan Cancer Registry. The follow-up period was from Jan. 1993 to Dec. 1998. Cancer free controls were randomly selected by 1:4 individual matching, which took in to consideration the year of birth and gender. Information on confounders was collected by a mail questionnaire survey. The odds ratios, and their 95% confidence intervals, were calculated using a conditional logistic regression model. RESULTS: After adjusting for a history of gastric ulcer symptoms, medication history, and body mass index, the adjusted OR (aOR) was 4.6 (95% CI=1.72-12.49). The odds ratio of long term use (more than 7 days) was 2.3 (95% CI=1.07-4.82). The odds ratio of short term use was 4.6 (95% CI=1.26-16.50). The odds ratio of parenteral use was 4.4 (95% CI=1.16-17.05) and combination use between the oral and parenteral routes (aOR, 16.8; 95% CI=1.21-233.24) had the high risk of gastric cancer. The aOR of cimetidine was 1.7 (95% CI=1.04-2.95). The aOR of ranitidine was 2.0 (95% CI=1.21-3.40). The aOR of famotidine was 1.7 (95% CI=0.98-2.80). CONCLUSION: The intake of H2-RAs might increase the risk of gastric cancer through achlorhydria in the elderly.

Ciliary neurotrophic factor (CNTF) is well known as a growth/survival factor of neuronal tissue. We investigated the expression of CNTF and its specific receptor alpha (CNTFRalpha) in a unilateral ureteral obstruction (UUO) model. Complete UUO was produced by left ureteral ligation in Sprague-Dawley rats. The animals were sacrificed on days 1, 3, 5, 7, 14, 21, and 28 after UUO. The kidneys were fixed, and processed for both immunohistochemistry and in situ hybridization. CNTF immunoreactivity in sham-operated kidneys was observed only in the descending thin limb (DTL) of the loop of Henle. In UUO kidneys, CNTF expression was induced in the S3 segment (S3s) of the proximal tubule from day 1, and progressively expanded into the entire S3s and a part of the convoluted proximal tubules, distal tubules (DT), and glomerular parietal epithelium up to day 7. Upregulated CNTF expression was maintained to day 28. From day 14, the inner medullary collecting duct showed weak CNTF immunoreactivity. The CNTFRalpha mRNA hybridization signal in sham-operated kidneys was weakly detected in the DTL, DT, medullary thick ascending limb, and in a few S3s cells. After UUO, CNTFRalpha mRNA expression increased progressively in both the renal cortex and the medulla up to day 7 and increased expression was maintained until day 28. The results suggest that the S3s may be the principal induction site for CNTF in response to renal injury, and that CNTF may play a role in chronic renal injury.
