Nineteen patients with lichen striatus were investigated by clinical data, clinical photographs and histopathologic study by the pattern analysis method of Ackermsn. Results were as follows '. 1. The male to female ratio was 1: 1.1, and average age was 7.8 years. Seven- teen patients (about 90%) visited hospitals during summer season. 2. Nine cases showed superficial perivascular dermatitis, 9 cases interface dermatitis (vacuolar type : 7, lichenoid type, 2), 1 case nodular dermatitis and 2 rases interface dermatitis with nodular dermatitis. 3. In the epidermis, 9 cases showed variable nurnber of dyskeratotic cells. One case showed finding of perforating lichen striatus. 4. Two cases showed inflammation around acrosyringium, 4 cases around hair follicle, 6 cases around eccrine sweat gland and 1 case showed perineural inflamrnation. Summarizing above results, histopathology of lichen striatus characteristically shows superficial perivascular dermatitis, interface dermatitis, and infiltration of inflammatory cells around the sweat gland, which helps to diagnose the disease.

OBJECTIVES: To confirm the HAVS in workers exposed to hand-arm vibration with using the objective diagnostic methods METHODS: Several tests were used to help substantiate a clinical diagnosis of HAVS. Some other diseases were excluded by a medical interview, hematologic assessment, urinalysis, X-rays. The hand-arm vibration acceleration level of the grinder was evaluated for considering HAVS. Peripheral vascular changes were examined by a cold provocation test. An electromyography was implemented to ascertain the peripheral neural changes. RESULTS: 8 workers with symptoms in hands & fingers, exposed to hand-arm vibration were examined. Some other diseases(primary Raynauds disease, secondary Raynauds disease in not occupational origin) were excluded by a medical interview, hematologic assessment, urinalysis, X-rays. The hand-arm vibration acceleration level of the grinder was 7. 9 m/sec2. The recovery time of a skin temperature followed finger cooling was significantly prolonged in 6 workers with HAVS. The nerve conduction velocity was reduced in 6 workers with HAVS. CONCLUSIONS: So we report 6 cases of HAVS in grinding workers exposed to hand-arm vibration diagnosed objectively by an exclusion of some other disease, handarm vibration acceleration level, cold provocation test, electromyography.

PURPOSE: To determine computed tomography (CT) criteria for cardiomegaly. MATERIALS AND METHODS: We analyzed posteroanterior chest radiographs and CT scans of 200 patients (M:F=130:70, mean age 49 years old) that were performed on the same day. On plain radiographs, the cardiothoracic ratio (R) was calculated using a standard method. On CT, we measured the maximal cardiac width (D(c)) and the maximal thoracic width of a patient (D(t1)). A second thoracic width was measured at the same scan level of D(c). Thus, two cardiothoracic ratios were derived in one patient-D(c)/D(t1) (R(1)) and D(c)/D(t2) (R(2)). We analyzed the appropriateness of R(1) and R(2) in the diagnosis of cardiomegaly to establish criteria for the use of the cardiothoracic ratio (ROC curve). RESULTS: When cardiomegaly was defined as a value of R that was greater than 0.5, both R(1) and R(2) were useful indicators of cardiomegaly. For a cut-off value of 0.5 for the cardiothoracic ratio for cardiomegaly, the sensitivity of R(1) and R(2) was 84% and 68%, respectively, and the specificity of R(1) and R(2) was 72% and 86%, respectively. CONCLUSION: The cardiothoracic ratio on CT can be easily obtained by measurement of the maximal cardiac width divided by the maximal thoracic width at the same scan level. When the cardiothoracic ratio on CT is over 0.5, the presence of cardiomegaly can be suggested.
