Osteochondrodysplasia is a heterogeneous group of disorders appearing short limbed dwarfism. Because many of these entities are lethal and hereditary, an accurate diagnosis is mandatory. The purpose of this study is to define the clinicopathologic features and radiologic findings of osteochondrodysplasia. We reviewed 29 autopsy cases of congenital short limbed dwarfism, consisting of thanatophoric dysplasia (TD) (12 cases), osteogenesis imperfecta (OI) (12 cases), asphyxiating thoracic dysplasia (ATD) (3 cases), short-rib-polydactyly syndrome (SRPS) (1 case) and hypochondrogenesis (1 case). The gestational age ranged from 16 to 41 weeks. Of 6 fetuses that were born alive, 3 were ATD, 2 were TD and 1 was hypochondrogenesis. TD was frequently complicated by hydramnios. Of 8 cases studied chromosomally, only 1 showed chromosomal abnormality -46XY, inv 9. Intrauterine growth retardation was frequently associated with OI. Pulmonary hypoplasia was present in 23 cases (79%), including all cases of ATD, SRPS and hypochondrogenesis, 11 in TD and 7 in OI. Other associated anomalies were present in 17 cases (59%).

With the aim of establishing bio-indices for the development of multistep hepatotumorigenesis, rats were fed water containing 0.01% diethylnitrosamine (DEN) ad libitum for 13 weeks. This treatment with DEN only made it possible to induce hepatic tumors in 100%. After the DEN administration, several clinical symptoms were observed including minor behavioral changes, brittleness of hair and a decrease in water and food intake. The concentration of total serum protein and albumin in all treated groups was significantly lower than in non-treated controls (p<0.05). Increase of specific enzyme (AST, ALT and GGT) activity (p<0.05), variable tumor size and hepatomegaly of the liver was observed in all rats treated with DEN for 10 weeks. Both hepatocellular carcinoma and cholangiocarcinoma were found in the same livers at the same time, and were prominently developed after 12 weeks. In case of carcinoma, some of the livers showed more or less advanced states over the 12-15 weeks period. In the present study, hepatocellular carcinoma was developed by treating DEN in only the drinking water, without any other carcinogens or without partial hepatectomy. These results indicate that DEN is a new carcinogen that acts directly on it the liver, moreover, it might be very useful for investigating hepatotumorigenesis.

This study is performed to evaluate usefulness of dermal measurement of benzidine and benzidine based dye as one of the occupational exposure assessment method for these compounds. We selected one benzidine manufacturing factory and one dye manufacturing factory in Incheon area. Eleven workers were for benzidine manufacturing factory and twenty four for dye. We analyzed relationships among air level, amount on skin and concentration of urinary metabolites for these compounds. Airborne levels of benzidine and dye were measured by NIOSH 5509, 5013 methods. Amount of these compounds on skin was measured with skin wipe method. Concentration of benzidine metabolites in urine was measured by High Performance Liquid Chromatography after alkaline hydrolysis. The amount of benzidine on hand skin was 25.05( - 233.2) ng/ur, and the amount of the neck was 2.01 ( - 11.9) ng/cm2 in the benzidine dihydrochloride manufacturing factory. The amount of benzidine on hand and neck skin has positive correlation with concentration of urinary monoacetyl benzidine (r=0.644, p < 0.05) . The amount of benzidine based dye on hand skin was 55.75( - 457.7) ng/cm2, and the amount of the neck skin was 18( - 284.7) ng/cm in benzidine based dye manufacturing factory The amount of dye on hand and neck skin has positive correlation with concentration of urinary benzidine for dye workers (r=0.467, p < 0.05). When assessing the exposure of workers who deal with benzidine, the amount of benzidine on skin should be measured for an accurate exposure assessment.

Halo dermatitis (Meyerson's nevus) is an inflammatory, eczematous eruption usually encircling a preexisting melanocytic nevus. Spontaneous healing occurs within several weeks or months and is never concurrent with regression of the central nevus, in contrast to halo nevus (Sutton's nevus). Although halo dermatitis is often associated with central melanocytic nevi, pathogenesis leading to the morphological change of this disorder remains obscure. Herein, we report a case of a 23-year-old female who developed an eczematous halo reaction surrounding the junctional nevi.

Supernummerary breast is a rare developmental anomaly occurring along the course of the embryological milk lines, which run from the anterior axillary folds to the inner thighs. Kajava first described the classification of supernumerary tissue in 1915, and this term is still in use. We herein report two cases of supernumerary breast, classified as Kajava classification type 3 and 6.

Verrucous carcinoma is a low-grade squamous cell carcinoma. It usually occurs in the oral cavity, genital or palmoplantar area. A 55-year-old woman presented with an asymptomatic, erythematous, round, hyperkeratotic nodule, of 0.8cm in diameter, on the left cheek. A skin biopsy revealed a typical verrucous carcinoma. We report herein an unusual case of verrucous carcinoma occurring on the face.

Eosinophilic pustular folliculitis (EPF) is a rare dermatosis of unknown cause. It is characterized by recurrent crops of sterile, pruritic, follicular papulopustules on the face, trunk, and extremities. Although various treatments have been attempted for EPF, including systemic corticosteroid dapsone, cetrizine, UVB phototherapy, as well as cyclosporin, no uniformly effective treatment has been found. We describe a 20-year-old man with long standing EPF which was resistant to various treatments, but who responded dramatically to indomethacin.

OBJECTIVE: To investigate psychological distress and fertility quality of life (FertiQoL) in infertile Korean women, and to investigate whether a correlation exists between psychological distress and FertiQoL. METHODS: Participants in this study were made up of 141 infertile women and 65 fertile women. We conducted a survey on psychological distress (using the Depression Anxiety Stress Scales [DASS]-42 questionnaire) and administered a FertiQoL questionnaire. The levels of stress hormones (adrenocorticotropic hormone [ACTH] and cortisol) in serum were assessed. RESULTS: The scores for depression (13.7±8.4), anxiety (10.7±6.4), and stress (18.0±8.3) among the infertile women were significantly higher than the scores for depression (9.4±7.5), anxiety (6.6±6.0), and stress (12.2±8.3, p<0.001) among the fertile women. There was no difference in the scores for depression (13.5±8.2, 13.8±8.6), anxiety (10.0±6.2, 11.5±6.6) and stress (17.7±8.4, 18.4±8.1) between younger (≤34) and older (≥35) participants. The mind-body (r =–0.495) and emotional (r =–0.590) subscales showed a higher negative correlation with stress compared with other scales of psychological distress. At the same time, the social (r =–0.537) and relational (r =–0.385) subscales showed a higher negative correlation with depression. Levels of cortisol and ACTH in infertile women were 9.1 µg/mL and 11.9 pg/mL, respectively, which are within normal ranges. CONCLUSION: The levels of psychological distress and quality of life in infertile Korean women seem to require psychological intervention. This study provides a baseline measurement of psychological distress and FertiQoL in infertile women in Korea, which will be available for developing psychological interventions for infertile Korean women.

We report two autopsy cases that revealed the partial absence of the septum pellucidum with ventriculomegaly. In each case, the brain showed mild dilatation of both frontal horns of the lateral ventricles, normal third and fourth ventricles and no aqueductal stenosis. The posterior portion of the septum pellucidum was absent and the fornices were fused in a single midline nodule, abnormally displaced to a caudal position and lodged in the foramina of Monro. The brain base showed no apparent abnormalities; the optic nerves were well developed. We conclude that the caudally displaced fornix in the absence of the septum pellucidum may have intermittently obstructed the foramina of Monro and induced mild ventriculomegaly.

Eight major policies were implemented by Japanese Government since Oct. 2001, to deal with bovine spongiform encephalopathy (BSE). These are; 1) Surveillance in farm by veterinarian, 2) Prion test at healthy 1.3mi cows/yr, by veterinarian, 3) Elimination of specified risk material (SRM), 4) Ban of MBM for production, sale use, 5) Prion test for fallen stocks, 6) Transparent information and traceability, 7) New Measures such as Food Safety Basic Law, and 8) Establish of Food Safety Commission in the Cabinet Office. At this moment, the extent of SRM risk has only been indicated by several reports employing tests with a limited sensitivity. There is still a possibility that the items in the SRM list will increase in the future, and this indiscriminately applies to Japanese cattle as well. Although current practices of SRM elimination partially guarantee total food safety, additional latent problems and imminent issues remain as potential headaches to be addressed. If the index of SRM elimination cannot guarantee reliable food safety, we have but to resort to total elimination of tissues from high risk-bearing and BSE-infected animals. However, current BSE tests have their limitations and can not yet completely detect highrisk and/or infected animals. Under such circumstances, tissues/wastes and remains of diseased, affected fallen stocks and cohort animals have to be eliminated to prevent BSE invading the human food chain systems. The failure to detect any cohort should never be allowed to occur, and with regular and persistent updating of available stringent records, we are at least adopting the correct and useful approach as a reawakening strategy to securing food safety. In this perspective, traceability based on a National Identification System is required.
