A case of malignant melanoma is described. The patient, 67 years old male, had thumb tip sized two tumor masses with linear arcuate spread on left upper back near spine of 3 months duration, and metastatic lesion on right axillary lymphnode. Lesions were removed surgically and split skin graft was done.

6 cases of nevus sebaceus of Jadassohn were reported and its literatures were reviewed. It is thought to be rather rare disease in this country. Two of the cases were seen within the age of 2 years and showed the clinical pictures of early stage. The remaining 4 cases were the clinical pictures of late stage showing verrucous lesions. All cases developed the lesions in the scaIp except case 6 which appeared on anterior neck. One of thc cases was associated with syringocystadenoma papilliferum but none of the cases show any association of basal cell carcinoma.

Management of the small lower ureteral stone has been attempted by either transurethral manipulation or expectant therapy. To date, however, the choice of proper method has depended mostly on clinician's preference, and the effectiveness of the transurethral stone manipulation has remained controversial. Herein we evaluated the effectiveness of the transurethral stone manipulation, using with the Dormia dislodger, in 37 patients with lower ureteral stone less than 10mm in greatest diameter. The results are summarized as follows. 1. The overall success rate was 68% (25 of 37 patients); Immediate delivery of the stone was observed in 16 of 37 patients. In another 5 patients the stone was removed at the time when the indwelled ureteral catheter was taken out. In the remaining 4 patients the stone passed spontaneously within a week following the procedure. 2. Higher success rate was observed in smaller stone; 79% in less than 4 mm, 58% in 46 mm, and 33% in 610 mm in it's greatest diameter, respectively. 3. The morbidity rate was 8.1% (3 of 37 patients); In one patient a broken basket was retained in the ureter, which was removed at the time of ureterolithotomy. In another patient a ureteral stricture requiring periodic dilation was complicated. And in the other patient persistent hematuria was observed, which was relieved by conservative management. These results suggest that transurethral manipulation might have to be initially applied to unremittingly painful patients with small lower ureteral stone.

Uric acid, pure or admixed, calculous disease during childhood is uncommon. We recently encountered a case of multiple calcium-uric acid urolithiasis in a l7-month-old male patient presented with anuria owing to bilateral complete obstruction of the ureteropelvic junction in which acute renal failure developed following emergency removal of the stones.

Inverted vesical papilloma is an uncommon, probably benign neoplasm with distinctive histologic features. It usually presents with hematuria and lower urinary tract obstruction due to hall-valve effect. We report a case of vesical inverted papilloma, which was proved histologically, causing lower urinary tract obstruction.

We investigated to see whether an altered role of nitric oxide (NO) system is involved in erythropoietin (EPO)-induced hypertension in chronic renal failure (CRF). Male Sprague-Dawley rats were five-sixths nephrectomized to induce CRF. Six weeks after the operation, EPO or vehicle was injected for another 6 weeks. Plasma and urine nitrite/nitrate (NOx) levels were determined. Expression of NO synthase (NOS) proteins in the aortae and kidneys were also determined. In addition, the isometric tension of isolated aorta in response to acetylcholine and nitroprusside was examined. Blood pressure progressively rose in CRF groups, the degree of which was augmented by EPO treatment. Plasma NOx levels did not differ among the groups, while urine NOx levels were lower in CRF groups. Endothelial NOS expression was lower in the kidney and aorta in CRF rats, which was not further affected by EPO-treatment. The inducible NOS expression in the kidney and aorta was not different among the groups. Acetylcholine and sodium nitroprusside caused dose-dependent relaxations of aortic rings, the degree of which was not altered by EPO-treatment. Taken together, EPO-treatment aggravates hypertension in CRF, but altered role of NO system may not be involved.

BACKGROUND: Although paclitaxel is a widely used chemotherapeutic agent for the treatment of solid cancers, side effects such as neuropathic pain lead to poor compliance and discontinuation of the therapy. Ethyl pyruvate (EP) is known to have analgesic effects in several pain models and may inhibit apoptosis. The present study was designed to investigate the analgesic effects of EP on mechanical allodynia and apoptosis in dorsal root ganglion (DRG) cells after paclitaxel administration. METHODS: Rats were randomly divided into 3 groups: 1) a control group, which received only vehicle; 2) a paclitaxel group, which received paclitaxel; and 3) an EP group, which received EP after paclitaxel administration. Mechanical allodynia was tested before and at 7 and 14 days after final paclitaxel administration. Fourteen days after paclitaxel treatment, DRG apoptosis was determined by activated caspase-3 immunoreactivity (IR). RESULTS: Post-treatment with EP did not significantly affect paclitaxel-induced allodynia, although it tended to slightly reduce sensitivities to mechanical stimuli after paclitaxel administration. After paclitaxel administration, an increase in caspase-3 IR in DRG cells was observed, which was co-localized with NF200-positive myelinated neurons. Post-treatment with EP decreased the paclitaxel-induced caspase-3 IR. Paclitaxel administration or post-treatment with EP did not alter the glial fibrillary acidic protein IRs in DRG cells. CONCLUSIONS: Inhibition of apoptosis in DRG neurons by EP may not be critical in paclitaxel-induced mechanical allodynia.

Epidural adhesions cause pain by interfering with the free movement of the spinal nerves and increasing neural sensitivity as a consequence of neural compression. To remove adhesions and deliver injected drugs to target sites, percutaneous epidural adhesiolysis (PEA) is performed in patients who are unresponsive to conservative treatments. We describe four patients who were treated with a newly developed inflatable balloon catheter for more effective PEA and relief of stenosis. In the present patients, treatments with repetitive epidural steroid injection and/or PEA with the Racz catheter or the NaviCath did not yield long-lasting effects or functional improvements. However, PEA and decompression with the inflatable balloon catheter led to maintenance of pain relief for more than seven months and improvements in the functional status with increases in the walking distance. The present case series suggests that the inflatable balloon catheter may be an effective alternative to performing PEA when conventional methods fail to remove adhesions or sufficiently relieve stenosis.

Mycobacterium kansasii is the second most common cause of nontuberculous mycobacterial pulmonary disease in Western countries and Japan. The clinical and radiological features of pulmonary disease caused by M. kansasii usually resemble those of pulmonary tuberculosis including cavitary infiltrates with an upper lobe predilection. It is also now apparent that patients with M. kansasii pulmonary disease can present with noncavitary nodular bronchiectatic infiltrates similar to lung diseases of M.avium complex. With rifampin-containing regimens, treatment success rates are almost 100%. Timely diagnosis before the development of extensive disease and effective overall treatment strategies are very important to ensure that patients receive the appropriate medications for a sufficiently long period of time. To our knowledge, there has been no Korean case report of M. kansasii pulmonary disease in the immunocompetent patient until now. We report three cases of M. kansasii pulmonary disease in immunocompetent adult patients.
