We report two cases of hyalinizing trabecular carcinoma (HTC) of the thyroid gland. These two patients were euthyroid women aged 36 and 65 years of age. The tumors were encapsulated and measured 0.8 and 4.0 cm in diameter, respectively. Histologically, the tumors were composed of a compact proliferation of cells in a lobular and trabecular pattern with an intervening hyalinized, fibrotic vascular stroma. Occasionally the cells were arrayed in microfollicles. Multiple and serial sections showed cords of tumor cells invading into the capsule in both cases and vascular invasion in one case. These findings suggested that HTCs are a malignant counterpart of hyalinizing trabecular adenoma, similar to conventional follicular tumor. Positive immunostaining of tumor cells for thyroglobulin and negative staining for high molecular weight cytokeratin, cytokeratin 19, neuron specific enolase, chromogranin, and synaptophysin allowed distinction from medullary carcinoma. Even though HTCs are an heterogeneous group of tumors, the present two cases are probably variants of follicular carcinoma rather than papillary carcinoma.

Renal dysplasia results from aberrant metanephric histogenesis caused fundamentally by a defect in inducer tissue or responding tissue. Dysplastic kidneys vary tremendously in gross and microscopic appearance but are characterized by abnormal organization and a mixed population of primitive structures, such as fetal or immature cartilage, dysplastic ducts, immature tubules, and undifferentiated mesenchyme. We report a case of unilateral multicystic renal dysplasia associated with an ipsilateral ectopic ureteral orifice entering a seminal vesicle cyst in a 33-year-old man. He was admitted due to primary infertility which had developed three years ago. The his semen analysis revealed oligospermia. No evidence of a family history of renal dysplasia was reported. Microscopic examination showed that the entire kidney was composed of cysts lined by flattened cells, dysplastic ducts and immature tubules surrounded by collars of spindle cells, primitive mesenchyme, and a few aberrantly formed glomeruli.

The purpose of this study was to explore the effect of diabetic camp program on depression, self-efficacy and self-esteem of the juvenile diabetic patient who had participated with diabetic camp program at Seoul and Kyung In area from August 5 to August 9, 1995. Nursing staffs explained them how to respond to the questionnaire of depression. self-efficacy and self-esteem prior to beginning the program and following the program. The questionnaire of depression, self-efficacy and self-esteem was developed by both diabetes mellitus nurse specialist and pediatric nursing professors in reference with the previous research. Response items of the questions were structured as yes or no for the elementary school students and that of the questions were structured as 5 likert scale for the both middle and high school students. Paired t-test was used for the significance of the difference between values before and after the diabetic camp program. Depression decreased following the program, while self-esteem increased significantly following the program in elementary school students. There was no change in self-esteem, while self-efficacy increased significantly following the program in middle and high school students. Self-efficacy following the program was high as the frequency of exercise increased in the elementary school students. Self-efficacy prior to the program was high as the experience of diabetic education increased in the middle and high school students. Self-efficacy and self-esteem prior to the camp was highly correlated with that following the camp in middle and high school students. The result suggests that diabetic camp program could be on of ways to decrease depression and to increase self-efficacy of the diabetic children.

PURPOSE: Suction ring is needed to fix the cornea during LASIK procedure. But if we choose the suction ring inappropriately, we meet the various problems such as conjunctival edema, conjunctival hemorrhage, ocular pain, and prolongation of operation time. To investigates various factors affecting the thickness of suction ring(1-4) in LASIK procedure. METHODS: We performed LASIK procedure by using SCMD microkeratome and VISX STAR laser on 398 eyes from Dec. 1996 to Feb. 1999. We compared difference on pachymetry, keratometry, corneal diameter, spherical equivalent according to the thickness of suction ring and analyzed these factors with One-Way ANOVA test. RESULTS: The results are that keratometry affected size of suction ring significantly. The flap size and hinge size are affected by size of suction ring significantly, but others did not show significant results. CONCLUSIONS: These results suggest that we need to choose the size of suction ring according to keratometry during LASIK procedure for decreasing various complications.

A study was made of the differences in clinical features and immunological aspects between herpes zoster patients with malignancies and those without malignant tumors. The results obtained from the retrospective review of medical records are as follows: Herpes zoster occurred more frequently in younger patients(less than twenty) with malignanciee as compared with the control group of the same ages,' Male was dominant among zoster patients with malignancies as is the contrary to contral group; Tihere were no marked differences in primarilly involved dermatomes between the two groups; Generalized varicelliform eruptiona were more common in zoster pa,tients with malignaneies than in control group, It seemed that zoster patients with malignancies complained of milder degree of pain. Zoeter patienta associated with malignancies were more frequently DNCB-negative and had decreased OKT3+ pan T cells, OKT4+ helper/inducer T cells as compared with control group, which suggest impaired cell mediated immunity in the former.

Recent investigations have revealed that autocrine growth factors and their receptors are closely related and play an important role in controlling cancer cell growth. We performed an immunohistochemical study on the expression of epidermal growth factor (EGF), transforming growth factor-alpha (TGF-alpha), epidermal growth factor receptor (EGF-R), c-erbB-2, and PCNA labelling index in 60 cases of human gastric carcinomas. TGF-alpha was detected in 38 cases (63.3%), EGF in 26 cases (43.3%), EGF-R in 44 cases (73.3%), and c-erbB-2 in 18 cases (30%). These growth factors, EGF-R and c-erbB-2, were found more often in advanced gastric cancers. The PCNA labeling index was significantly higher in tumors with the expression of EGF-R or c-erbB-2. Tumors with simultaneous expression of EGF, TGF-alpha, EGF-R and c-erbB-2 was associated with a high PCNA labeling index. A correlation was observed between the synchronous expression of growth factors and its receptors and histological differentiation. The results suggest that the expression of EGF, TGF-alpha, EGF-R and c-erbB-2 are closely related and plays an important role in the growth and progression of human gastric carcinoma.

FitzGerald and Jankovic(1989)' reported 10 patients with marked gait difficulty and no or only minimal upper limb involvement and coined the term 'lower body parkinsonism' (LBP). They further suggested that LBP was a homogeneous subgroup of parkinsonism, distinct from idiopathic Parkinson's disease (IPD), attributable to vascular etiology. In order to verify the validity of this clinical entity, five cases with LBP were compared with 44 cases with typical idiopathic Parkinson's disease (IPD) with respect to their clinical and neuroradiological findings. Mean age at onset was significantly older in LBP group (63.2*6.3 years) than IPD group (53.9*5.9 years). Gait disturbance was the initial motor symptom in 80% of LBP cases and 16% of IPD cases. Duration of symptoms tended to be shorter in LBP group than IPD group (3.2*2.7, 5.2*3. Lyears, respectively), although statistically not significant. Response to, L-dopa was poor in all but one case with LBP, while most cases with IPD showed good response (43 of 44 cases). On brain MRI in LBP group, four of five cases had multiple small ischernic lesions in both periventricular white matter and basal ganglia. However, one case with LBP showed normal brain MR finding and improved with L-dopa treatment, whose diagnosis proved to idiopathic Parkinson's disease. We conclude that LBP is unusual but not rare, and may be a part of clinical spectrum of either vascular parkinsonism or idiopathic Parkinson's disease. Although LBP is a heterogeneous group, most cases may be caused by multiple lacunar infarctions.
