Spontaneous testicular hemorrhagic necrosis is a rare disease usually associated with testicular torsion. Partially involved and suspicious testis tumor cases are also defined from orchiectomy specimens. Herein, a spontaneous hemorrhagic necrosis, without any testicular torsion, but with involvement of the whole testicle and epididymis, is reported. A 21 year old patient, who presented with a painless left testicular enlargement of several days duration was believed, based on physical examination, ultrasonography and elevation of serum LDH, to have a testicular tumor. Diagnosis was made only after radical orchiectomy and histopathological examination.

BACKGROUND: Nowadays, acute drug intoxication is a important section of emergency medicine. The purpose of this study was to determine what is the best-way to manage acutely intoxicated patients with drug in emergency department setting. METHODS: Clinical assessment were made on 135 cases of drug intoxication visited to emergency center of Hospital during one year from June 1997 to May 1998. RESULTS: 1. The total number of cases of acute drug intoxication was 135 which is 0.5% of total patients presented to emergency center. 2. There was no sexual difference in incidence, but the highest incidence of age group was in 3rd decade(23.7%) and the next was 7th decade(20.0%). 3. High frequency of acute intoxication was observed in autumn. October had the largest portion in monthly distribution. The largest portion of presumed time of poisoning was noon - 4 p.m. and of the time on arrival to emergency center was 8 p.m. -midnight. 4. Suicidal attempt was the most common motive of intoxication (72.6%). 5. The most common drug of intoxication was insecticides (35.7%) and the others were centrally active agents, herbicides in orders. 6. Mental change was observed in 20.7% of patients and the abnormal vital signs were hypertension, tachycardia, and hypotension in order on arrival to emergency center. 7. Mean duration of treatment was 36.1 hours. Mortality rate of the cases was 7.4%. CONCLUSION: The mortality rate was high in patients who ingested relatively fatal drugs (i.e. herbicides, antimicrovials, insecticides), showed mental change on arrival or received mechanical ventilatory care(p<0.05).

Pleomorphic (undifferentated) carcinoma is a rare histologic type of carcinomas of the gallbladder and an atypical carcinoid is thought to be an intermediated type between carcinoid tumor and small cell carcinoma. Dense core "neurosecretory" granules can be found in the above mentioned tumors. We experienced a case of a double tumor of the gallbladder in a 51-year old male patient. Grossly, a large solid mass, about 5.0 cm in diameter, was found in the fundic portion and the neck portion also had a small 1.5 cm-sized polypoid mass. Microscopically, these lesions had features of pleomorphic carcinoma and atypical carcinoid, respectively. Immunohistochemically, they manifested reactivity for neuron specific enolase. Ultrastructural study revealed neurosecretory granules in the cytoplasms of tumor cells of the fundic and neck masses. Although light microscopic features of these tumor masses are quite different, we consider that these tumors represent a spectrum of neuroendocrine differentiation.

Regionalization of high-risk perinatal care has been advocated because intensive care for small and ill newborn infants lowers mortality and morbidity. This report is based on analysis of admissions to the Neonatal Intensive Care unit (NICU) at the Wonju christian Hospital during the 4-year period from January, 1988 to December, 1991. There were 786 inborn infants and 1155 outborn infants admitted to the NICU. The results of our study follow; 1) Mean gestational ages were 36.8 weeks in inborn infants and 39.0 weeks in outborn infants. Mean birth weight was 2.5kg in inborn and 3.0kg in outborn infants. 2) The high-risk maternal factors, such as cesarian section delivery, eclampsia, preeclampsia, multiple pregnancy and placental anomaly were significantly more frequent in inborn infants than in outborn infants. 3) Perinatal sphyxia, HMD and transient tachypnea of newborn (TTN) were more common in inborn than in outborn infants, but pneumonia, meconium aspiration syndrome, and seizure were more common in outborn infants. 4) The positivity of bacterial cultures in blood and urine was higher in outborn infants than in inborn infants. The most frequently isolated microorganism was staphylococcus species in both inborn and outborn infants. 5) Hospital days, duration of TPN, duration of mechanical ventilation, frequency of seizure, and frequency of transfusion were longer or more frequent in inborn than in outborn infants. 6) Mortality rate was higher in inborn infants than in outborn infants. 7) In outborn infants, mortality rate was higher in infants whose transporting time was longer than 2 hours than for infants within 2 hour distances. However, this difference was not statistically significant. 8) These findings suggest that many lower birth weight and severly ill infants were not transported to the NICU of Wonju Christian Hospital perhaps due to poor transport systems, distance or socio-economic status. In conclusion, the improvement of transporting systems and socio-economic conditions will be required within this region.

We report a case of bilateral bridges of atlas of a Korean atlas and accompanying variation of the course of the left suboccipital nerve that was observed during the practice of the human anatomy in Seonam university, college of medicine. Bridges of atlas across the groove for the vertebral artery run inferomedially from the posterior margins of the superior articular processes to the posterior margins of the grooves. Widths of the narrowest middle portions of the bridges are 5.05 mm at the left and 0.7 mm at the right. Superior and inferior widths of left bridge are 11.6 mm and 10.9 mm, and of the right are 4.45 mm and 4.65 mm respectively. Cross-sectional areas of the foramina formed by bridges of atlas are 34.7 mm 2 at the left and 29.3 mm 2 at the right. These sizes are much smaller than the sizes of the transverse foramina of the atlas at each side, but diameters of the second and third portions of the left vertebral artery are same as 4.3 mm. At the junction between the left bridge and the posterior arch distinct suture line was observed. Because of the relatively wide bridge, the left suboccipital nerve runs more laterally than the right. It turns to the posterior, pierces the obliquus capitis inferior muscle, and branches out to adjacent suboccipital muscles. Branch to the rectus capitis posterior muscles obliquely cross over the suboccipital triangle to these muscles.

Seven patients with average age of 15years and 6 months (range: 8 years and 11 months 25 years and 6 months) underwent forearm lengthening by callotasis. The indications for lengthening were shortening and/or deformity of the forearm due to exostosis of the distal ulna in three cases, growth disturbance due to physeal injury of the distal radius in three, congenital radial dislocation in one. Three had lengthening of the radius, three of the ulna and one of both the radius and the ulna. The average lengthening achieved was 3.8 cm (3.5 - 4.0) in radius, 2.7 cm (2.3 - 3.0) in ulna. Complications encountered were pin tract infection in two cases, nonunion in one and temporary nerve palsy in one. All of these complications were recovered completely without any residua. Retrospective review after average 41 months of follow-up (range: 36 to 78) showed satisfactory improvement in appearance and function. Callotasis was considered as one of the safe and reliable treatment methods for bone lengthening and deformity correction of the forearm.

The purpose of this study is to confirm the effectiveness of stay-suture which is commonly used in the procedure of end to end anastomosis, to find out general biomechanical properties of peripheral nerve with gradual stretching and to evaluate the histological difference after breakage of the nerve. The sciatic nerves of adult rabbits were excised and they were grouped by I and II. Group I was composed of 14 normal sciatic nerves and group II, 14 sciatic nerves sutured with 5-0 nylon after transection. They were stretched on the "Instron" universal testing machine at a constant rate of 200mm/min until breakage took place and the results were compared. The mean maximal tensile strength was 13.6N in group I and 2.1N in group II, representing about one seventh value. The mean ultimate tensile strength was 4.2MPa in group I and 0.9MPa in group II, representing about one fifth value. In load-elongation curve of group I, viscoelastic property was noted as all other biological tissues have. The mean modulus of elasticity was 19 in normal sciatic nerves, which is somewhat lower value than other tissues, indicating superior elastic property of peripheral nerves. Transverse histologic examination showed that epineurium lost its continuity earlier than perineurium, implying perineurium is a more resistant structure than epineurium. However, to confirm this, it is thought to be necessary to examine the nerves serially during distraction at each different status. In conclusion, stay-suture provided about one fifth of ultimate tensile stress, implying its usefullness of resisting excessive tension in end to end anastomosis of peripheral nerves. Normal sciatic nerves showed viscoelastic property with mean modulus of elasticity of 19.
