BACKGROUND: The skin prick test and in vitro allergen-specific IgE assays are commonly used to diagnose atopic diseases. However, there is still a need for comparison of their diagnostic efficiency. Objective and METHOD: To evaluate their clinical efficiency, the results of UniCAP and multiple antigen simultaneous test (MAST) were compared with skin prick test results. After 51 allergic patients completed skin prick test (SPT), serum sample was collected and UniCAP and MAST were performed to determine specific IgE to house dust mite (Dermatophagoides pteronyssinus : Dp and D. farinae. Df). Result : When SPT was used as a reference standard, UniCAP depicted higher sensitivity of 88.8% to Dp IgE and 91.4% to Df - IgE, but lower specificity of 73.3% to Dp IgE and 75.0% to Df - IgE. However, MAST had lower sensitivity of 75.1% to Dp-IgE and 71.4% to Df - IgE, higher specificity of 93.3% to Dp-IgE and 93.7% to Df - IgE. The values of UniCAP and MAST were significantly correlated with the reactivity grade of skin prick test, respectively. Additionally, the response of SPT was not apparently associated with ECP levels. CONCLUSION: These study results may suggest that both UniCAP and MAST are generally feasible for measuring house dust mite - specific IgE and that they are both replicable.

bcl-2 and c-myc protein expression were studied in 44 epidermal (8 seborrheic keratoses, 21 squamous cell carcinomas, and 15 basal cell carcinomas), and 26 melanocytic tumors(8 nevi, and malignant melanomas) by immunohistochemistry using the specific anti-bcl-2 and anti-c-myc monoclonal antibodies. 14 out of 15 basal cell carcinomas(BCC) (93.3%) showed expression of bcl-2 protein, 12 of which (85.7%) showed coexpression of c-myc protein. In the melanocytic tumors, 7 out of 8 nevi showed bcl-2 expression (87.5%). Five of these 7 cases (62.5%) also showed c-myc protein expression. Eight of 18 malignant melanomas(MM) (44.4%) showed expression of bcl-2 protein and 7 of these 8 cases (38.9%) also showed c-myc protein expression. All seborrheic keratoses and squamous cell carcinoma(SCC) were negative for bcl-2 proteins. 12 of 15 SCCs(80%) were positive for c-myc protein. In conclusion, bcl-2 and c-myc proteins were coexpressed in BCCs, nevi, and MMs. Coexpression of bcl-2 and c-myc proteins in these tumors was statistically significant(p<0.01), while no considerable differences of bcl-2 and c-myc expression were found between nevi and MMs. These results suggests that bcl-2 may cooperate with c-myc to promote tumorigenesis of BCCs, nevi, and MMs(p<0.01).

Accelerated atherosclerosis is not only a frequent complication but also the most common cause of death in patients with chronic renal failure (CRF). Although mechanisms are unclear, disorder of lipid metabolism may be a major factor. Since apolipo-protein (apo) E is known to play a major regulatory role in lipid metabolism, we evaluated apo E genotype in 72 male patients with CRF and compared with that in 194 rnale normal controls. In addition, we measured plasma lipid and apolipoprotein concentrations and evaluated them according to apo E genotype in patients and controls. Apo E genotype was determined with the INNO-LiPA Apo E kit (Innogenetics, Belgium), which is based on reverse hybridization. The results are as follows ; 1) The distribution of the three major apo E alleles in patients with CRF ( e 2: 6.2%, e 3: 80.6%, e 4: 13.2%) was not different from that in controls ( e 2: 4.1%, e 3: 87.6%, e 4: 8.3%). 2) In patients with CRF, total cholesterol, lowdensity lipoprotein (LDL) and high-density lipoprotein (HDL) levels were significantly lower and the triglyceride and lipoprotein (a) levels were significantly higher than those in controls. 3) In controls, E 4/3 group had significantly lower levels of HDL than E 3/3 and E 3/2 groups. In patients with CRF, E 4/3 group had significantly higher levels of total cholesterol and apo B lipoprotein than E3/2 group. In conclusion, although there was no significant difference in the apo E genotype frequencies between male patients with CRF and controls, apo E polymorphism may play an important role in the determination of individual differences in plasma lipids in male patients with CRF.

Five adult cases of post-laminectomy swan-neck deformity are reported. The factors causing the deformity, prophylactic measures, and treatment of the deformity are discussed. It is strongly adviced to the neurosurgeons and orthopedic surgeons that they should be aware of this unwanted complication of the multi-level cervical laminectomies, and that they should provide every preventive measures before post-laminectomy swan neck deformity develops. Anterior interbody fusion spanning the entire unstable segments is preferably recommended together with application of pre-fusion traction.

Pulmonary alveolar proteinosis(PAP) is a rare disease in which the alveolar spaces are filled with an eosinophilic, PAS-positive material, whereas the interstitial architecture of the lung usually remains unaffected. Although a definitive diagnosis is usually made by an open lung biopsy, bronchoalveolar lavage(BAL) cytology may play a decisive role in the diagnosis and therapy of these patients and may spare a patient a more invasive diagnostic procedure. The author presents a patient in whom BAL cytology specimen contained the characteristic globules of amorphous proteinaceous PAS-positive material accompanied by background of rare macrophages and inflammatory cells. Ultrastructural study using BAL specimen can confirm the diagnosis of PAP.

Adenoid cystic carcinoma of the uterine cervix is a rare tumor accounting for less than 1% of all cervical adenocarcinoma. This tumor is characterized by aggressive biological behavior with frequent local recurrence or metastatic spread, postmenopausal onset, and occasional association with conventional squamous cell carcinoma. The cytologic diagnosis of adenoid cystic carcinoma in the uterine cervix is often difficult because of negative smear due to intact overlying mucosa, cytologic findings mimicking endometrial cells, and masquerade as squamous cell carcinoma. Recently we have experienced a case of adenoid cystic carcinoma arising in the uterine cervix, which was identified on the routine Papanicolaou smear and was histologically confirmed by the consequent biopsy. The smear showed abundant cellularity composed of relatively uniform cells. The tumor cells were arranged in small clusters, acini, naked cells, and loose sheets with abortive cribriform pattern. There were scattered globoid basement membrane-like materials and tumor diathesis. The nuclei were pleomorphic and showed hyperchromatic and coarsely granular choromatin with inconspicuous nucleoli. The punch biopsy of the uterine cervix showed typical histologic findings of adenoid cystic carcinoma characterized by tumor nests composed of hyperchromatic uniform basaloid cells, cribriform pattern, and cylindrical hyaline bodies.

A rare case of hepatic metastasis with a choriocarcinomatous component from a composite adenocarcinoma and choriocarcinoma of the sigmoid colon in a 60-year-old man is reported. The hepatic metastasis displayed choriocarcinoma with extensive hemorrhagic necrosis. The tumor cells were poorly differentiated with scattered foci of bizzare syncytiotrophoblastic cells. Retrospective examination of the previous colonic carcinoma proved that the tumor was composed of two distinctive elements. One was a moderately well differentiated adenocarcinoma located in mucosa and submucosa. The other was a deep seated and undifferentiated carcinoma which was made up of hyperchromatic bizzare cells with syncytiotrophoblastic cells. There were transitional foci from adenocarcinoma to undifferentiated carcinoma with trophoblastic cells. Immunohistochemical staining showed beta-hCG expression in the undifferentiated cells of both the primary and the metastatic tumors. Implications for the possible origin and cause of tumor cell heterogeneity are briefly discussed.

We studied two intraabdominal desmoplastic small cell tumors. The patients were two men, 37 and 23 years old, with jaundice and palpable abdominal masses. On exploratory laparotomy, each patient revealed a huge mass in the greater omentum with disseminated peritoneal seeding, measuring 32 cm and 11 cm in its greatest dimension, respectively. The tumor involved the diaphragm, rectal shelf, and cul de sac in case 1, and it involved the porta hepatis, retroperitoneum, and serosal surface of the ascending and transverse colon in case 2. Omentectomy of the huge mass and satellite masses was performed in each patient. Both tumors showed nearly the same histopathologic features. The histologic pattern was suggestive of a metastatic small cell carcinoma, but there was no specific, single primary site. The tumors consisted of variably sized, discrete islands of epithelial-like small cells in dense desmoplastic stroma. The tumor cells revealed divergent epithelial, mesenchymal, and neural differentiation by histologic, immunohistochemical, and electron microscopic observations. Only one cycle of chemotherapy including cisplatin and VP-16 was given in case 1 because of a subsequent hepatic problem, who, thereafter, showed massive intraabdominal recurrent tumors 6 months after diagnosis. In case 2, the poor condition of the patient had made chemotherapy and radiotherapy impossible. Case 2 died of disseminated intravascular coagulation following progressive cachexia 7 months after diagnosis.
