Proper management of childhood and adolescent varicocele remains still controversial. In general, all methods for varicocele ablation for adults are available and include open surgical ligation, laparoscopic ligation, or percutaneous ablation. We evaluated the usefulness of percutaneous embolization of internal spermatic vein in boys with varicocele. Between February 1988 to May 1996, 48 boys of 53 varicoceles underwent percut aneous embolization. In 49 cases, the embolization were technically possible and in the other 4 cases, we could not access the internal spermatic vein because of vasospasm and venous abnormality. The results were successful in 40 cases (81.6%) and failed in 9 cases (18.4%), including 4 (8.2%) of persistent and 5 (10.2%) of recurred cases. There were no major complications except 3 cases of extravasation of contrast material. Percutaneous embolization may be recommended as a primary treatment for childhood and adolescent varicocele.

OBJECTIVE: To establish a supraorbital nerve sensory conduction recording method and assess its usefulness. METHODS: Thirty-one healthy subjects without a history of trauma or neurological disease were recruited. For the orthodromic procedure, the recording electrode was attached immediately superior to the supraorbital notch. The stimulation electrode was placed on points along the hairline which evoked the largest sensory nerve action potentials (SNAPs). The antidromic sensory response was recorded after switching the recording and stimulating electrodes. The measured parameters were onset latency, peak latency, and baseline to peak amplitude of the SNAPs. The electrophysiological parameters of the bilateral supraorbital nerves were compared. We also recruited two patients who had sensory deficits on one side of their foreheads because of laceration injuries. RESULTS: The parameters of orthodromically recorded SNAPs were as follows: onset latency 1.21±0.22 ms (range, 0.9-1.6 ms), peak latency 1.54±0.23 ms (range, 1.2-2.2 ms), and baseline to peak amplitude 4.16±1.92 µV (range, 1.4-10 µV). Those of antidromically recorded SNAPs were onset latency 1.31±0.27 ms (range, 0.8-1.7 ms), peak latency 1.62±0.29 ms (range, 1.3-2.2 ms), and baseline to peak amplitude 4.00±1.89 µV (range, 1.5-9.0 µV). There was no statistical difference in onset latency, peak latency, or baseline to peak amplitude between the responses obtained using the orthodromic and antidromic methods, and the parameters also revealed no statistical difference between the supraorbital nerves on both sides. CONCLUSION: We have successfully recorded supraorbital SNAPs. This conduction technique could be quite useful in evaluating patients with supraorbital nerve lesions.

Primary pulmonary hypertension is a rare and progressive disease with poor prognosis. Despite much previous studies, there is neither clear explanation in the etiology and the pathogenesis nor confirmative treatment modalities. Its main cause of death is due to the right ventricular failure but the left ventricular function is relatively well preserved. The chest pain mimickig the angina pectoris is common and it is mostly due to the right ventricular ischemia or distension of pulmonary artery, but left ventricular ischemia or infarction is very rarely seen. We experienced a case of primary pulmonary hyperetension with left ventricular hypertrophy that complicated to acute myocardial infarction in 14-year-old male.

PURPOSE: This study was performed to investigate whether the free to total PSA ratio(F/T PSA ratio) offers a better discriminant for the detection of patient with prostatic cancer(CaP) and those with benign prostatic hyperplasia(BPH) than serum total PSA alone. MATERIALS AND METHODS: From September 1996 to February 1999, free and total PSA levels were measured on frozen sera samples of 154 men with BPH and 46 with CaP using immunoradiometric assay. RESULTS: In all subjects, the mean total PSA was significantly higher in CaP group(72.59+/-66.58ng/ml) than BPH group(3.12+/-4.10ng/ml). The mean PSAD was significantly higher in CaP group(1.64+/-1.86) than BPH group(0.08+/-0.01). The mean F/T PSA ratio was significantly lower in CaP group(0.19+/-0.07) than BPH group(0.30+/-0.13). Among 41 subjects whose total PSA were between 4-20ng/ml, the mean PSAD was significantly higher in CaP group(0.37+/-0.16) than BPH group(0.17+/-0.07), but the mean F/T PSA ratio was not significantly different between CaP(0.19+/-0.10) and BPH group(0.25+/-0.13). By comparing the sensitivity and specificity of total PSA alone, PSAD and F/T PSA ratio on receiver operating characteristic(ROC) curve in all subjects and subjects with total PSA between 4-20ng/ml, F/T PSA ratio had no superiority than total PSA alone and PSAD for. discrimination between CaP and BPH. CONCLUSIONS: We suggest that the F/T PSA ratio is not superior to total PSA alone and PSAD in the detection of prostatic cancer, and further evaluation of the usefulness of F/T PSA ratio should be required.

Placenta accreta is a rare complication of pregnancy with high rates of maternal morbidity and mortality.It is usually discovered when removal of the placenta after delivery is difficult or there is substantial postpartum bleeding.Placenta accreta can be complicated by disseminated intravascular coagulation (DIC) and this increases maternal morbidity and mortality.DIC is characterized by the widespread activation of coagulation, which results in the intravascular formation of fibrin and ultimately thrombotic occlusion of small and midsize vessel.We report a 24-year-old woman with DIC, who developed severe pre- and intraoperative bleeding and massive transfusion during emergent cesarean section.
