PURPOSE: To compare the usefulness of double-dose contrast-enhanced CT (DDCE-CT) and conventional contrast-enhanced CT (CCE-CT) in the detection of metastatic brain lesions. MATERIALS AND METHODS: Sixteen patients with brain metastases were evaluated with both CCE-CT and thinslice DDCE-CT. For CCE-CT, an initial injection of 100 ml contrast medium was given, and DDCE-CT with both 10-mm and 5-mm thickness was performed after the addition of an extra 100 ml of contrast medium. The numbers of metastatic lesions detected by CCE-CT and by DDCE-CT were compared, as were the findings of contrast-enhanced MRI (CE-MRI) and thin-slice DDCE-CT in seven patients who underwent both these procedures. RESULTS: Fourteen metastatic brain lesions were detected by CCE-CT, 22 by 10-mm-thickness DDCE-CT, and 36 by 5-mm thickness DDCE-CT. Thus, almost 2.6 times more lesions were detected by thin-slice DDCE-CT than by CCE-CT. Metastatic lesions were detected by 10-mm-thickness DDCE-CT in 16 patients and by CCECT in seven; in five, edema only was detected, while in four there were no detectable metastases. CCE-CT detected four lesions of less than 5 mm in diameter, while 10-mm-thickness DDCE-CT and 5-mm-thickness DDCE-CT detected seven and 18 lesions, respectively. Eleven lesions were detected by thin-slice DDCE-CT and 17 by CE-MRI in the seven patients who underwent both CE-MRI and DDCE-CT. The lesions detected only by CE-MRI were less than 5 mm in diameter and were discovered in the cerebellum or inferior temporal lobe. CONCLUSION: Thin-slice DDCE-CT was superior to CCE-CT in detecting metastatic brain lesions.

We investigated the feasibility of the extracorporeal suture technique in laparoscopic pyeloplasty and laparoscopic ipsilateral ureteroureterostomy in child with ureteropelvic junction obstruction or duplex kidney. Laparoscopic pyeloplasty and laparoscopic ureteroureterostomy were performed in a child with ureteropelvic junction obstruction and in a 3-year old child with duplex kidney, respectively. Ureteropelvic junction or ureters were dissected laparoscopically and were drawn out of the abdominal cavity through the 10mm trocar tracts and subsequently anastomosed extracorporeally. We were able to draw the ureteropelvic junction or the ureters out of the abdominal cavity without difficulty owing to the laxity and thin abdominal wall in children. Operating time was 120 minutes in both cases, and all anastomses between ureter and pelvis were completed without any intraoperative complication. There was no postoperative complication. Significant improvements in urinary drainage were shown in both children on postoperative intravenous pyelogram. These early results suggest that the extracorporeal suture technique in children is feasible and easy to perform. Therefore, the drawbacks of intracorporeal suture technique during the laparoscopic pyeloplasy or ureteroureterostomy could be overcome by using this novel teehnique.

Nicolau syndrome, also known as livedoid dermatitis or embolia cutis medicamentosa, is a rare cutaneous adverse drug reaction characterized by the acute onset of cutaneous and soft-tissue necrosis following intramuscular drug injection. The typical presentation is pain around the injection site, developing into erythema, a livedoid patch, and necrosis of the skin, subcutaneous fat, and muscle tissue. We report a 72-year-old man who presented with a painful, erythematous patch on his left buttock. The patient was treated with non-steroidal anti-inflammatory drug (diclofenac sodium) injection.

PURPOSE: This study aimed to evaluate the preliminary treatment results of fractionated stereotactic radiotherapy (FSRT) for metastatic brain tumors. MATERIALS AND METHODS: Between August 1997 and December 1998, frameless FSRT was performed in 11 patients with metastatic brain tumor (1S lesions). Primary sites were lung in 7 patients, breast in 2, stomach in 1, and malignant melanoma in 1, All patients received 30-36 Gy/10-20 fx external beam irradiation to whole brain. Eight patients received FSRT for 1 lesion, one for 2 lesions, and two for 4 lesions. Fractionation schedule was 25 Gy/5 fx in 11 lesions, 18 Gy(1 fx in 3, 30 Gy/5 fx in 2, 15 Gy/5 fx in 1. Mean tumor volume was 7.0 cc (0.39~55.23 cc). Multiple-arc FSRT was delivered to 16 lesions and conformal FSRT through irregular ports shaped to tumor profile to 2 lesions. RESULTS: No patient experienced any acute side reaction from FSRT. Follow-up radiologic evaluation was available in 9 patients. Six of nine patients achieved the complete response, but two showed the partial response and one showed no response on follow-up radiologic studies. Among six patients with complete response, 5 patients survived from 5 to 15 months and showed no evidence of metastatic brain d#isease clinically and/or radiologically at last follow-up. Among two patients who did not have radiologic evaluation, one showed clinically complete response until death and the other died just after FSRT caused by intercurrent disease. One patient with no response radiologically survived 7 months and showed nearly complete disappearance of clinical symptom with stable status radiologically, CONCLUSION: Initial experience in this study suggests that the external beam irradiation to whole brain with 30 Gy/10 fx followed by FSRT with 20~30 Gy/5~6 fx could be the good treatment option to the patients with metastatic brain tumor. This study suggests that the fractionation schedule for FSRT should be determined in consideration of performance status, number of metastasis, tumor volume, location, presence of extracranial disease, and age.
