We Reviewed 10 hypertensive children with pheochromocytoma retrospectively and the following results were obtained. 1) Out of 10 patients, 7 were male and 3 female. Age ranged from 5.5 years to 13.8 years and their median age was 9.9 years. 2) They complained of sweating, lethargy, headache. or chest pain and so on. Hypertension were noticed in all patients. Heart murmurs were detected in 7 patients and hypertensive retinopathy in 70%. 3) The three cases arised at extraadrenal gland and bilaterality was seen in 3 patients. In the view of diagnosis, abdominal sonography, computerized tomography and urine VMA test revealed the sensitivity of 100%. But MIBG scan showed 60% in sensitivity. 4) Waiting for operation, their hypertension were controlled by adrenergic blockers or calcium channel blockers. They received tumorectomy successfully except one who was in hypertensive state after operation and followed up through OPD. In conclusion high suspicion for the existence of pheochromocytoma from the clinical manifestations should be entertained in any pediatric patients and biochemical and imaging studies were mandatory. Furthermore, for the accurate localization of tumors, several imaging studies should be collaborated.

PURPOSE: In order to compare stone metabolic risk factors in recurrent stone formers, we researched lithogenic factors according to sex and age. MATERIALS AND METHODS: We performed stone metabolic studies on recurrent stone formers (77 men, 33 women) and grouped them according to age; under 40 (n=38), from 40 to 59 (n=56) and over 60 (n=16). We evaluated excretion rate differences of lithogenic and inhibitory constituents such as volume, sodium, uric acid, calcium, oxalate, and citrate from 24-hour urine samples, and calcium, sodium, uric acid, phosphate, potassium, and chloride from serum samples. We analyzed the incidence of stone metabolic risk factors between the age groups and the sexes. RESULTS: The most common detectable risk factor in all groups of recurrent stone formers was hypocitraturia. This finding was more remarkable in males aged under 60. The incidence of hypocitraturia was higher in males and in the younger group, whereas hypercalciuria was more frequent in the elder group. CONCLUSIONS: The most important cause of urolithiasis was hypocitraturia in recurrent stone formers, and this was apparent in males aged under 60.

Evaluations of residual renal function and the therapeutic effectiveness in renal tuberculosis have largely been dependent on intravenous pyelogram or Contrast-CT scan, even though, exact renal function are not evaluated with there methads. 99mTc-DMSA is a radiopharmaceutical that is trapped in the functioning tubular cells of the kidney and therefore, quantitative renal function could be evaluoted by ineasuring the counts of renal radioactivity and concomittant evaluation of renal morphology could be passible with the analog imapes of the radioactivity. The authors retrospectively analyzed 99mTc-DMSA scans of 75 kidndys of 67 patients with confirmed renal tuberculosis. We classified the morphologies of tuberculous kidneys as 6 types. We classified the morphologies of tuberculous kidneys as 6 types such as the type with small cortical defect, with parenchymal ulcerocavernous lesions, ulcerocavernous fistula to pelvis, mass-like defects, contracted kidney with ureter visualization, and the type with nonvisualization of kidney, corresponding to the characters of renal tuberculous pathogenesis with abscess formation, ulcerocavernous fistula, and fibrosis, and correspondings to the renal anatomy with parenchyma, and pelvocalyceal collecting system. Their mean residual renal functions measured with 99mTc-DMSA uptake rates were 19.0%, 18.4%, 7.9%, 12%, 4.1%, 3.4% respectively.

BACKGROUND: Primary stenting as a direct reperfusion procedure after acute myocardial infarction might reduce recurrent myocardial infarction and target vessel revascularization. However, result of long or multiple stenting in the long or tandem lesions were not known. METHOD: From Jan. 1996 to Dec. 1998, patients with acute myocardial infarction including cardiogenic shock were undergone primary stenting using long or multiple stent. The clinical end points were death, recurrent infarction, subsequent bypass surgery, or repeat angioplasty of the infarct-related vessel. The results were compared with age, sex, lesion, and risk matched standard stenting group. RESULT: Baseline characteristics were similar for the 20 patients who underwent standard length stenting and the 13 patients who underwent long or multiple stenting. Stent diameter was similar in two group (3.4+/-0.3 mm vs. 3.5+/-0.4 mm, p=0.65), but total stent length was longer in long or multiple stenting group (15.5+/-1.8 mm vs. 40.18.4 mm, p=0.01). Average numbers of stent using in multiple stenting were 1.5+/-0.7. Stenting in the infarct-related artery was successful in all patients randomized to stent treatment. At 6 months, the incidence of the primary end point was 25% (5/20) in the standard stent group and 31%(4/13) in the long or multiple stent group (p=0.5). CONCLUSION: Outcomes of long or multiple stenting including mortality, recurrent myocardial infarction and target vessel revascularization was similar to standard stenting. Long or multiple stenting after acute myocardial infarction may possible procedure in some selective cases having long or tandem lesion.

Aortopulmonary fistula is an exceedingly rare vascular malformation. It is commonly derived after chest injuly or from complication of chest operation and aortic dissection and congenital aortopulmonary fistula is only several cases combined with Tetralogy of Fallot or aortic stenosis. But a congenital aortopulmonary fistula without any hemodynamic abnormalities was not reported. A 56-year old man with exertional dyspnea was admitted. In an examination on admission, there were no abnomalities. Aortography showed an aortopulmonary fistula that branches from the ascending aorta adjacent to the right coronary artery, running to the main pulmonary artery. Transcatheter coil embolization was performed and he was discharged 7 day after embolization without complication. Exertional dyspnea disappeared and careful follow up has be performed periodically.

We describe a 23-year-old man showing typically clinical and histological features of targetoid hemosiderotic hemangioma. About 35 cases of this newly-described entity have been reported since the first description by Santa Cruz and Aronherg in 1988. It is important to distinguish these tumors from patch stage Kaposi's sarcoma, retiform hemangioendothelioma and progressive lymphangioma.

PURPOSE: This study was designed to verify intermediate-term functional and radiological results of limb salvage operation using endoprosthetic replacement system (MUTARS(R)) used in patients with a malignant bone tumor. MATERIALS AND METHODS: Thirty one cases which used MUTARS(R) tumor prosthesis were reviewed. The mean age of the patients was 49.2 years and the mean follow up was 39.8 months. We retrospectively reviewed complications, and evaluated functionally and radiologically by Enneking functional score, ISOLS radiological implants evaluation system at last follow-up. RESULTS: 3 patients had died of disease, distant metastasis was seen in 4 patients and local recurrence was seen in 1 patients. Complications were developed in 12 patients. (infection 6, leg length discrepancy 2, aseptic loosening 2, periprosthetic femoral fracture 1, screw loosening 1) Mean value of total functional scores were 81.2% in proximal femur, 77.4% in distal femur, 78.1% in proximal tibia, and 80.2% in proximal humerus. The overall radiological result was relatively satisfactory. CONCLUSION: Our results suggest limb salvage with the MUTARS(R) endoprosthesis is successful with good functional and radiological results. But we should be careful with complications such as infection.
