Percutaneous gastrostomy, ballon dilatation, and metallic stent placement are the most common interventional procedures in radiology for the GI tract. Percutaneous gastrostomy provides nutritional support for patients with a debilitating disease or major swallowing difficulty. The most common candidates are patients with cerebral vascular accidents. Percutaneous gastrostomy is associated with a lower morbidity than surgically or endoscopically placed gastrostomy catheters and is also less expensive. Benign strictures of the GI tract are generally treated by balloon dilatation. Very tight strictures usually require stepwise dilation, beginning with a small balloon and gradually increasing the balloon diameter. Balloon dilatation is technically successful in more than 90% of patients, and functional success is achieved in 86∼90%. Metallic stents are used to manage strictures or obstructions in the esophagus and GI tract. For the esophagus, stent placement has been used effectively in the treatment of malignant dysphagia and is now a well-established procedure. The technical success rate approaches 100% and improvements in the dysphagia score ranges from 83% to 100%. From the successful use in the esophagus, stents have been employed in the stomach, duodenum, and colon. Metallic stents are currently an estalished component of the nonsurgical management of gastroduodenal and colorectal obstructions. Metallic stents within the stomach, duodenum, or colon are used for nonsurgical palliation of the symptoms of gastric or colonic obstruction rather than as a curative procedure. This palliation is intended to improve the quality of life in patients with an unresectable disease or used as an interin procedure prior to a definitive surgical management.

We report a case of eosinophilic pustular folliculitis (EPF) with associated plantar lesions in a 45-year-old man. Exarnination of the skin disclosed an erythematous patch, approximstely 3 x 5cm, on the left cheek, which contained discrete and confluent pspulopustules and scaly circinated vesicular patch on the right foot. Histologic examination of a biopsy specirnen from the left cheek revealed the hair follicles and the sebaceous glands are infiltrated mainly by eosinophils and by some mononuclear and neutrophils. Histologic examination of a biopsy specimen from the right foot revealed a vesicle extending from the subcorneal portion to the lower epidermis, which was filled with neutrophils and a small number of eosinophils.

Though many effort,s have been made to develop a safe and effective treatment to control osmidrosis, no such goal has been achieved yet. A subcutaneous shaving method, developed by Inaba, appeared to be a favorable choice because of minimal postoperative scar formation. The authors, with this method operated on 112 cases of osmidrosis and compared the results with those of conventianal surgical therapy performed earlier in our department. The results were as follows : 1. The. average age at the time of the operation was 22.0 years old, and the sex ratio between male and female was 37 to 75. 2. The age onset ranged from 11 to 36 years with average of 15.5 years. 3. Family history for osmidrosis was found in 84.8%. 4. General anesthesia were used in 13 cases, while 99 cases were operated under local anesthesia. 5. The mean duration for operation were 75 minutes. 6. Flematoma were observed in 4.5%, wound disruption in 1.3%, and skin necrosis in 3.1%. 7. The results of analysis in 72 follow up cases for more than 6 months showed: 1). Rate for successful reduction of the malodor was 91.7%. 2) The rate of suppression of sweating was 88.9%. 3) The rate of skin tensian with motion was 2.8%. 4 ) The, pstoperative scars were mild or invisible in 95.1%

We studied the biological effects of Mitomycin C(MMC) in cellular metabolic activity and cytotoxicity on the corneal epithelial cell in rabbit that is clinically used according to MMC concentrations and exposure time. The concentration of MMC were 0.01%, 0.02%, 0.04%, 0.06%, 0.1%, and exposure time were 5, 10, and 30 minutes. MTT assay (3-I4,5-Dimethy-lthiazol-2-ylI-2,5-diphenyltetrazolium bromide) and transmission electromicroscopic examination were performed to access the metabolic activity of corneal cell, toxicity of corneal epithelial cell, and cellular morphology. In calorimetric assay, the higher the concentration of MMC and longer the duration of exposure time, the cellular metabolic activity was decreased. Also the toxicity of corneal epithelial cell was increased in a concentration and time dependent manner. The metabolic activity of corneal cell were inhibited by 50% at least over MMC 0.04% for 30 minutes exposure time. The LD50 at 5 minutes exposure was MMC 0.057%. In histologic finding, the higher the concentration of MMC, the change of cellular structure such as loss of microvilli, enlargement of rough endoplasmic reticulum or mitochondria, damage of nuclear membrane were more appeared. To obtain the efficacy of MMC for inhibition of cellular proliferation, we think that further experimental and clinical studies should be need to assess the safe concentration and exposure time of MMC to the corneal toxicity.

PURPOSE: We evaluated the effectiveness of balloon dilatation and bougienage of post operative anastomotic stricture of upper G-I tract. MATERIALS AND METHODS: We performed 22 balloon dilatation and 24 Bougienage in 40 patients of post operative anastomotic stricture. The causes of operation were esophageal cancer(n=20), stomach cancer(n=16), laryngeal cancer(n=2), chemical(n=2) strictures. RESULTS: Successful dilatations of the anastomotic site stricture were achieved during the procedure in 38 patients(95%). There was one case of esophageal perforation as a complication. CONCLUSION: Esophageal balloon dilatation and Bougienage are safe and effective method for post operative anastomotic site stricture of upper G-I tract.

We present a case with congenital absence of the infrarenal portion of inferior vena cava and lilac venous system, showing unusual venous collaterals including the left ovarian venous collateral via parametrial venous complex, and a mesenteric-periureteric venous connection. The venous collateral pathways were demonstrated by computed tomography and venography.
