The choroid plexus papillomas are uncommon neoplasms of the central nervous system, and constitute 0.5~0.6 percent of intracranial tumors. These tumor are surgically treatable and the encouraging results of surgical removal justify an aggeressive surgical approach. We present a case of lateral ventricle choroid plexus papilloma in a child with communicating hydrocephalus.

According to the Jastreboff's neurophysiological model of tinnitus, if negative associations are attached to the tinnitus signal, tinnitus is perceived to be a threat or a danger and it activates the autonomic nervous and limbic systems. Consequently patient's awareness of tinnitus is heightened and so patient perceives it to be louder and more persistent. Jastreboff and Hazell started tinnitus retraining therapy (TRT) based on the neurophysiological model of tinnitus. The purpose of TRT is blocking tinnitus from activating the sympathetic nervous and limbic systems (habituation of reaction) and from reaching the cerebral cortex (habituation of perception). TRT is composed of two components directive counseling that tries to reclassify tinnitus into the meaningless stimuli and sound therapy that decreases the relative strength of the tinnitus signal. Physicians try to put patient's tinnitus into the territory of meaningless stimuli through retraining the brain (habituation of reaction). Because the brain habituates all unimportant stimuli, if habituation of reaction is fully achieved, habituation of perception will follow automatically. In most clinical results, clinical success rates of TRT approach or exceed 80% improvement. Early improvement can be achieved during the first few months, followed by additional progressive improvement. It should be recommended that the patient continue treatment at least 18 months.

The changes of phospholipase D (PLD) activity were investigated during the courses of apoptotic process induced by tumor necrosis factor (TNF)-alpha or anti-Fas/Apo1 antibody in human premyelocyte HL-60 and murine B cell lymphoma A20 cells. The treatment of recombinant TNF-alpha to HL-60 cells resulted in the increased PLD activity as determined by the phosphatidylethanol formation in the presence of 1% ethanol. The enhancement of PLD activity was also observed in the anti-Fas/Apo1 monoclonal antibody-treated A20 cells. However, the activity of PLD was maximized when HL-60 and A20 cells were treated with either TNF-alpha or anti-Fas/Apo1 monoclonal antibody for 6 h. Both TNF-alpha and anti-Fas/Apo1 monoclonal antibody increased PLD activity in a dose-dependent manner up to 200 U/ml and 200 ng/ml, respectively. When the intracellular activity of protein kinase C (PKC) was interrupted by treatment of calphostin-C, both the PLD activation and the apoptosis induced by TNF-alpha and anti-Fas/Apo1 monoclonal antibody appeared to be inhibited. Since PKC is reported to activate PLD, the results indicate that the intracellular signaling cascade via PLD may play a role in the induction of apoptosis induced by TNF-alpha and anti-Fas/Apo1 monoclonal antibody.

Cutaneous horn is a clinical term for a circumscribed concial hyperkeratotic mass amounts to at least half of its largest diameter. The number of lesion may be single or multiple. We report herein a cases of penile cutaneous horn in a 22-year-old male. He had dark brownish colored conical shaped protruded mass on the penile shaft for about 2 months. We performed excisional biopsy and curettage. Histopathologic findings showed verruca vulgaris.

We treated 19 patients with ureteral injuries during the recent 7 years. Gynecologic operations were the most common antecedent surgical procedures(89%). The diagnosis of ureteral injuries was made immediately in 3 patients and was delayed 3 to 78 days in 16 patients. All of the 3 injuries recognized during an operation were repaired at the time of injury. Of the 16 patients with injuries recognized in the postoperative period, 1 patient was managed with percutaneous nephrostomy. 14 patients received corrective surgery successfully, but the corrective surgery in remaining patient was railed and ultimately resulted in a nephrectomy because of avascular necrosis of ureter during operation. Therefore, it is better to do corrective surgery primarily in patients with ureteral injuries recognized postoperatively in order to decrease percutaneous nephrostomy associated morbidity and hospital admission period.

Hemorrhagic shock is one of the most common causes of death in patients with multiple trauma and therefore rapid control of bleeding is the main strategy to save these patients. Resuscitative balloon occlusion of the aorta (REBOA) has been applied in several trauma cases and because of the effectiveness of this procedure it has been adopted in the trauma field. Herein, we report the first successful case of REBOA in Korea performed on a 46-year-old man with hemorrhagic shock after a fall from a height of 14-stories. The patient visited our hospital emergency room with hypovolemic shock, we performed Resuscitative Endovascular Balloon Occlusion of the Aorta under bed side blind technique. His vital sign was stabilized after procedure, then we could performed endovascular bleeding control. The patient was discharged on his 33rd in-hospital day without invasive procedure and major scar.

Clinical observation was made on the injuries of genitourinary tract of in patient under 15 year in the department of urology, Hart Yang University Hospital during the period from May, 1972 to April, 1983. The results were as follows: 1. Of 3140 cases hospitalized, 30 cases were injury of genitourinary tract in children giving ratio of 0.96%. 2. The favorable age was from 7 to 9years for 40%. The sex ratio, male to female, was 4:1.3. Traffic. accident was the most frequent cause of injury (53.3%) and the ,next was fall-down (43.3%), especially 8 cases of fall-down were from playing. 4. The kidney was involved most frequently in 35.1% (8 cases were fight side) and urethra was next in 32.4%,external genitalia 21,6% bladder in 10.8%. 5. The fracture was the most frequent associated injury (71.4%) and it's sites of fracture were pelvis, femur, ribs, and etc. 6. Treatment of the renal injury was performed as conservative treatment frequently (66.7%) and 5 cases were undergone nephrectomy. Posterior urethra was involved more commonly and. preferable treatment was primary realignment with interlocking sound.
