We present a case of eccrine spiradenoma occurring on the trunk in a 33 year old woman. She developed a pea sized, pinkish tender nodule on the anterior chest 8 years ago. On histologic examination, there were several lobules surrounded by thin connective tissue septa in dermis. The lobules themselves consisted of small dark staining cells and large pale-staining cells, forming solid cords or ducts.

BACKGROUND: Pregnancy in human and rodents is associated with dramatic matemal metabolic changes. Insulin-like growth factors (IGFs) are mitogenic peptides that are essential for fetal and maternal tissue growth during pregnancy. They circulate complexed primarily with a serum IGF-binding protein (IGFBP-3) which regulates the availability of the IGFs to their specific target tissues. METHODS: To examine the changes of IGFs and IGFB-3 during pregnancy, we measured serum total IGF-I, free IGF-I, IGF-II and IGFBP-3 by using specific radioimmunoassay, immunoradio-metric assay, western ligand blot and western immunoblot. Blood samples were obtained from 88 pregnant women between 6-40 weeks gestation. RESULTS: While serum IGF-I levels increased up to 50% in late pregnancy, serum IGF-II levels remained unchanged. However, serum free IGF-I levels were significantly higher during pregnancy than in nonpregnancy. Western ligand blot analysis revealed that IGFBP-3 in pregnancy serum was significantly decreased at 6 weeks of gestation, continued decreased level until term, and returned to a nonpregnant level by postpartum 10 day. Serum IGFBP-3 profiles in Western immunoblot analysis revealed that 30 kDa fragments of IGFBP-3 were detectable in pregnancy serum but not in nonpregnancy serum. In contrast, serum IGFBP-3 levels using radioimmunoassay was significantly increased in late pregnancy. CONCLUSIONS: 1) serum IGF-I was significantly elevated in late pregnancy 2) serum IGF-II was not significantly changed 3) free IGF-I significantly elevated throughout gestation 4) intact IGFBP-3 was markedly reduced after 6 weeks of gestation.

A case of contact dermatitis due to herb onintment is described in a 24 year-old female patient. After topical application of herb ointment, she developed erythematous papules and plaques on the face and neck. Patch test revealed positive reactions to ammoniated mercury, thimerosal, and the herb ointment. Energy-dispersive X-ray microanalysis of the herb ointment showed a striking peak for mercury.

5.Initial Clinical Experience of Extracorporeal Shock Wave Lithotripsy using the Northgate SD-3 Lithotriptor.
Korean Journal of Urology 1990;31(2):235-241
Extracorporeal shock wave lithotripsy monotherapy was performed in 72 renoureteral units from 66 patients with the Northgate SD-3 lithotriptor using ultrasound stone localization between June 21, and August 25, 1989. Of 72 cases renal stones were 46 cases( 63.9% ) and ureteral stones 26 cases ( 36.1% ). No regional or general anesthesia were necessary but sedatives or analgesics were required in most patients. Among 67 cases who completed extracorporeal shock wave lithotripsy, the success rate of treatment(rate free of calculi plus that of clinically insignificant residual stone fragments) was achieved 100% below 20mm, 87.5% in 21-30mm and 100% over 31mm and the total mean success rate was 97%. 23 cases( 31.9% ) were required auxiliary procedures such as Double-J stent in 14 cases, push up procedures 6 cases and stone basket 3 cases. Poet-lithotripsy complications were transient macroscopic hematuria in 90%, renal colic 20.8%, steinstrasse 13.9%, fever 6.9% and subcapsular hematoma 2.8% and these complications were controlled with conservative management. We suggest that extracorporeal shock wave lithotripsy monotherapy with the Northgate SD-3 lithotriptor was considered to be effective and safe procedure for the initial treatment of urinary stone.

PURPOSE: The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyme and renal collecting systems are invaded simultaneously. MATERIAL AND METHOD: We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renalcontour bulging or reniform shape, location of mass center, intact parenchyme overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. RESULT:There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cellcarcinima, wherea and nine of 12 cases of transitional cell carcinoma maintained the reniform appearance. This is significant statiscal difference between the two(p<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(p<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, whereas 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(p<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(p<0.05). CONCLUSION: CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reniform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change.

In vivo ethane production in rats was used as an index of oxygen toxicity. The rats were allocated to four exposure conditions; hyperbaric oxygenation (HBO=5 ATA, 100% O2), normobaric oxygenation (NBO=1 ATA, 100% O2), hyperbaric aeration (HBA=5 ATA, 21% O2) and normobaric aeration (NBA=1 ATA, 21% O2). After 120 minutes of exposure, the rats exposed to high concentration and/or high pressure oxygen exhaled significantly larger amounts of ethane than those exposed to NBA, and the differences in ethane production between any two groups were statistically significant (p<0.01). This finding supports the hypothesis that hypothesis that hyperoxia increase oxygen free-radicals and the radicals produce ethane as a result of lipid peroxidation. It is notable that the ethane exhalation level of the HBA group was significantly higher than that of the NBO group. This difference could not be accounted for by the alveolar oxygen partial pressure difference between the two groups.

Angiosarcoma is a rare malignant vascular tumor of endothelial cell origin. Most lesions of cutaneous angiosarcoma occur over the face and scalp. We experienced a case of angiosarcoma of the scalp in a 63-year-old man. Multiple pea-sized erythematous papules and nodules developed on the forehead 6 months ago. Thereafter, the lesions have extended to make violaceous, compressible and hemorrhagic plaques. On histologic examination, there were irregular, often anastomosing vascular channels lined by the atypical endothelial cells in the dermis.
