The hyperimmunoglobulinemia E (Jobs) syndrome (HIES) is characterized by marked elevated levels of IgE, recurrent cutaneous and systemic staphylococcal infections, atopic-like dermatitis, and defective neutrophil chemotaxis. Three cases of HIES have been reported in Korea, but not in the dermatology literature. We report a case of HIES with cutaneous infections and MRSA (methicillin-resistant Staphylococcus aureus). A 15-month-old girl presented with intractable pruritic excoriated papular pustular skin lesions and multiple subcutaneous abscesses. Surgical drainage of the abscesses and a course of antibiotic treatment in addition to topical steroids for about 7 weeks resulted in a remarkable improvement.

Dermoid cysts can be found anywhere in the body, particularly in areas where embryonic elements fuse together. Dermoid cysts arising in the head and neck lesion are relatively common, but that of nasolabial area has not been reported. Recently, we experienced a case of epidermoid cyst mimicking nasolabial cyst. The patient was a 49 year-old man with an anterior nasolabial swelling that has been presented for 1 year. After cyst excision, a histologic examination revealed that it was an epidermoid cyst. We report this case with the 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.

BACKGROUND AND OBJECTIVES: A large amount of information related to paranasal sinusitis is available on the internet; however, little is known about the quality and content of such information. We assessed paranasal sinusitis-related information on web sites of western and eastern physicians. MATERIALS AND METHODS: Using the search engine of Naver and Daum, a total of 159 web sites (108 by western physicians, 51 by eastern physicians) were identified by the keyword search "paranasal sinusitis" and were classified using the categories of location and field of contents. These web sites were evaluated for several aspects, and an informational value score was assigned to each. RESULTS: Regarding the location, Seoul (38), Gyeonggi (28), Busan (10) accounted for 70% of sites by western physicians, compared with 76% for the eastern physicians [Seoul (27), Gyeonggi (9), Busan (3)]. With respect to content, main content and Q/A were excellent in sites by eastern physicians whereas clinical schedule was excellent in those by western physicians. The mean informational value of the web sites was 5.17 for western physicians and 2.19 for eastern physicians (p<0.05). CONCLUSION: Web sites on paranasal sinusitis concentrated very firmly on metropolitan areas. Web sites by western physicians provided better paranasal sinusitis-related information than those by eastern physicians.

PURPOSE: Insulin-like growth factor binding protein (IGFBP-3) and phosphatase and tensin homolog (PTEN) are tumor-suppressor genes that may be involved in breast tumorigenesis. However, the roles of these genes in the regulation of breast cancer growth or progress are unclear. In this study, we aimed to find any correlation between the reduction of IGFBP-3 or PTEN protein expression in cancer tissues and the clinicopathological parameters in breast cancer. METHODS: We collected both cancer and adjacent normal tissues from 46 breast cancer patients (from January 1 to December 31, 2006), and checked the IGFBP-3 and PTEN protein levels in cancer and adjacent normal tissues using Western immunoblot. We evaluated the correlation of reduction status of IGFBP-3 and PTEN protein expression with variable clinicopathological parameters. RESULTS: The frequency of IGFBP-3 and PTEN protein reduction in cancer tissue, compared to adjacent normal tissue, was 63.0% and 34.8%, respectively. And in 87.5% of patients, who showed significant PTEN reduction, IGFBP-3 protein expression was reduced in cancer tissues. In contrast, IGFBP-3 protein reduced in only 50% of patients who didn't show PTEN reduction. However, we did not find any significant correlation between reduction of IGFBP-3 or PTEN expression in cancer tissue and variable clinicopathological parameters. CONCLUSION: The IGFBP-3 and PTEN genes were expressed in all breast cancer tissues. Nonetheless, we did not find any significant relationship between reduction of IGFBP-3 or PTEN expression and the clinicopathological parameters in this study. Therefore, further studies are needed to document the roles of IGFBP-3 and PTEN genes in breast cancer growth or progress.

In order to develop questionnaire estimating vinyl chloride monomer(VCM) exposure levels, to reset selection criteria for detailed tests, to measure current VCM exposure levels, to evaluate the mutagenic effects of VCM exposures and to develop multiphasic screening method of PVC- or VCM-handling workers, VCM concentrations of work environments were measured and tentative self-administrative questionnaire, physical examination, sister chromatid exchange(SCE) test and some clinical chemical test were applied to 195 men who had been handling VCM or PVC(Exposed Group) and 37, in the same factories without exposure to VCM or in polyethylene- or polypropylene-related factories(Control Group). Mean VCM concentrations of work environments were 0.268+/-0.183 ppm under PVC synthesis processes, 0.160+/-0.200 ppm under VCM synthesis process, 0.076+/-0.111 ppm under PVC pipe producing processes, 0.090+/-0.108 ppm under PVC wall paper, sheet, or film producing processes, 0.071+/-0.051 ppm under PVC floor producing processes, 0.243+/-0.250 ppm under PVC sash producing processes, and 0.020+/-0.031 ppm under triming process. VCM levels of work environments under manual resin mixing processes (0.209+/-0.168 ppm)were higher than those of the others (0.209+/-0.168 ppm) (p-value<0.05). There was no VCM-related symptoms, the positive response rates of which were higher in the Exposed Group. Overall abnormal rate in clinical chemistry test of the Exposed Group was higher than that of the Control Group, but due to extermely low exposure level of exposure group and to small sample size of the Control Group, no statistical significance was found(p-value>0.05). SCE frequencies of the Exposed Group were significantly higher than those of Contorl Group(p-value<0.05) and those of test-abnormal persons were higher than those of test-normal persons. SCE frequencies linearly increased with not only current but also cumulative VCM exposure levels(p-value<0.05). These results suggest that adverse health effect may ensue from VCM exposure to as low as 1 ppm. But SCE frequencies had no statistically significant correlation with drinking amounts, smoking amoutns, or radiation dose equivalents. Questionnaire was revised by referring to these results and formula estimating cumulative VCM exposure levels based on occupational history in questionnaire were made. In addition, were presented methods evaluating work environments and multiphasic screening test for PVC workers.

BACKGROUND: Cyclin-dependent kinase (CDK) inhibitors are family of molecules that regulate the cell cycle. The CDKN2, a CDK4 inhibitor, also called p16, has been implicated in human tumorigenesis. The CDKN2 inhibits the cyclin/CDK complexes which regulate the transition from G1 to S phase of cell cycle. There is a previous report that homozygous deletion of CDKN2 region on chromosome 9p21 was detected frequently in astrocytoma, glioma and osteosarcoma, less frequently in lung cancer, leukemia and ovarian cancer, but not detected in colon cancer and neuroblastoma. However, little is known about the relationship between CDKN2 and laryngeal cancer. Therefore this study was initiated to investigate the role of CDKN2 in human laryngeal squamous cell carcinoma development. MATERIALS AND METHODS: We used 5 human laryngeal carcinoma cell lines whether they have deletions or losses of CDKN2 gene expression by DNA-PCR or RT-PCR, respectively. We examined 8 fresh frozen human laryngeal cancer tissues to detect the loss of heterozygosity (LOH) of CDKN2. PCR was performed by using microsatellite markers of short arm of human chromosome 9 (D9S126, D9S144, D9S156, D9S161, D9S162, D9S166, D9S171, D9S200 and D9SIFNA). For informative cases, allelic loss was scored if the signal of one allele was significantly decreased in tumor DNA when compared to the same allele in normal DNA. RESULTS: The CDKN2 DNA deletion was observed in 3 cell lines. The CDKN2 mRNA expression was observed in only one cell line, which was very weak. LOH was detected in 7 cases (87.5%). CONCLUSION: These results suggest that CDKN2 plays a role in the carcinogenesis of human laryngeal squamous cell carcinoma.

Whole-body positron emission tomography (PET) with fluorine-18 fluorodeoxyglucose (18F-FDG) is a tomographic imaging technique that uses a radiolabeled analog of glucose, 18F-FDG, to image relative glucose uptake rates in various tissues. Since the glucose uptake is increased in many malignancies, 18F-FDG PET is a sensitive method for detecting, staging, and monitoring the effects of therapy on many malignancies. However, it is uncommon to discover an asymptomatic non-functioning pituitary tumor unexpectedly as a hypermetabolic lesion in PET studies. Here, we report a pituitary tumor that was detected incidentally by FDG-PET and ultimately turned out to be a non-functioning pituitary macroadenoma.

PURPOSE: Adhesive capsulitis is a clinical syndrome involving pain and decreased joint motion caused by thickening and contraction of the joint capsule. The purpose of this study is to describe the MR arthrographic findings of this syndrome. MATERIALS AND METHODS: Twenty-nine sets of MR arthrographic images were included in the study. Fourteen patients had adhesive capsulitis diagnosed by physical examination and arthrography, and their MR arthrographic findings were compared with those of 15 subjects in the control group. The images were retrospectively reviewed with specific attention to the thickness of the joint capsule, volume of the axillary pouch (length, width, height(depth)), thickness of the coracohumeral ligament, presence of extra-articular contrast extravasation, and contrast filling of the subcoracoid bursa. RESULTS: Mean capsular thickness measured at the inferior portion of the axillary pouch was 4.1 mm in patients with adhesive capsulitis and 1.5 mm in the control group. The mean width of the axillary pouch was 2.5 mm in patients and 9.5 mm in controls. In patients, the capsule was significantly thicker and the axillary pouch significantly narrower than in controls (p<0.05). Capsule thickness greater than 2.5 mm at the inferior portion of the axillary pouch (sensitivity 93%, specificity 80%) and a pouch narrower than 3.5 mm (sensitivity 93%, specificity 100%) were useful criteria for the diagnosis of adhesive capsulitis. In patients with this condition, extra-articular contrast extravasation was noted in six patients (43%) and contrast filling of the subcoracoid bursa in three (21%). CONCLUSION: The MR arthrographic findings of adhesive capsulitis are capsular thickening, a low-volume axillary pouch, extra-articular contrast extravasation, and contrast filling of the subcoracoid bursa. Capsule thickness greater than 2.5 mm at the inferior portion of the axillary pouch and a pouch width of less than 3.5 mm are useful diagnostic imaging characteristics.
