A morphometric study on the trigeminal ganglion and the intracranial portion of the ophthalmic, maxillary and mandibular nerves was done in 50 Korean adult cadavers. The shape of the ganglion was classified into 7 types and semicircular shape was most common (54%). Mean width of the trigeminal root at porus trieminus was 6.08mm. The length of the trigemnal root from porus to the trigeminal ganglion was 8.28mm at ophthalmic portion, 10.16mm at maxillary portion, and 8.90mm at mendibular portion. Maximum width of the ganglion was 15.48mm and the breadth of the ophthalmic, and maxillary portion were 5.25mm and 5.26mm, respectively, and that of the mandibular portion (4.92mm) was narrow than the other portion. Intracranial ophthalmic nerve was 4.30mm of width and 17.89mm of length, and this nerve inclined average 39.7。 (range 14.56。) from sagital plane. It was observed infrequently that the cavernous sinus extended to the lateral border of the maxillary nervw and the emissary sinus ran under the mandibular nerve.

The composition and the structure of the sacrum present the sexual and the racial difference. The variation of the structure is meaningful in the administration of caudal anesthesia which used one of the safest and the most valuable means of local anesthesia. In this study, a morphological investigation of the sacrum in Korean adults was done using 145 dry sacral bones. Non-metrical morphological variations were observed and ten measurements were undertaken. The results of the study were as follows. 1. The five segmented sacrum appeared most commonly (62.1%). Six segmented sacrum appeared 37.2% and the incidence tended to increse according to the age. Four segmented sacrum was noted in one case (0.7%). 2. In 9.7%, deficiences existed in the upper dorsal wall of the sacral canal. In 5.5%, deficiences existed in the middle of the dorsal wall of the sacral canal. 3. The apex of the sacral hiatus was found mostly (28.9%) at the upper third of the body of fifth sacral vertebra. 4. The sacral hiatus was classified into five groups by shape with triangular being the most frequent. 5. There was a significant sexual difference in the antero-posterior and transverse diameters of the first sacral vertebral body, the length of the sacrum, and the length of the sacral hiatus. 6. The average sacral index I was 98.2 in male, and 104.4 in female. Sacral index I was the relationship between the greaster breath to the length of the sacrum. 7. The average sacral index II was 46.6 in male, and 44.8 in female. Sacral index II was the relationship between the first sacral body diameter to the greaster breath of the sacrum. A thorough knowledge of the anatomical features of the dorsum of the sacrum including above results will lead to the decrease in the number of failures in administration of caudal anesthesia.

Hyperinsulinemic hypoglycemia is a relatively rare disease in childhood period except neonate, but hypoglycemia due to delicate imbalance between glucose production & consumption is evoked easily and left permanent damage to brain at these period. The definition is that serum insulin level is above 10microU/ml when blood sugar level is below the 40mg/dl and so I/G ratio is higher than 0.4. The clinical manifestations are irrtability, frequent feeding and seizures etc. and there is no specific pancreatic pathology in most cases. We experienced 2 cases of hyperinsulinemic hypoglycemia with pancreatic hyperplasia and pancreatic adenoma each other. The diagnosis was made on clinical manifestations, laboratory results, radiologic and pathologic findings. We reported these cases with brief review of literature.

BACKGROUND: This study was performed to compare anesthetic agents and adjuvants for general anesthesia or regional anesthesia between university hospitals, resident-training general hospitals and hospitals without training program of residents. METHODS: We surveyed university hospitals, resident-training hospitals and hospitals without training program of residents and divided randomly each hospital groups to become twenty hospitals. We compared the use frequency of inhalation anesthetics, muscle relaxants, induction agents, reversing agents, local anesthetics, premedicants, cardiovascular drugs and plasma expanders. RESULTS: Enflurane was most commonly used inhalation anesthetic in all hospital groups. Isoflurane was less commonly used inhalation anesthetic in hospitals without training program of residents. Pancuronium was most commonly used muscle relaxant in university hospitals. Midazolam, ketamine, fentanyl, propofol were commonly used induction agents during induction in university hospitals and resident-training general hospitals. Differences of use frequency of local anesthetics among hospital groups were not significant, but epinephrine mixing with local anesthetics was more frequent in university hospitals and resident-training general hospitals. Midazolam as a premedicant and norepinephrine, phenylephrine, amrinone, esmolol, pentastarch were less used in hospitals without training program of residents. CONCLUSIONS: These results suggest that university hospitals and resident-training general hospitals didn't show difference in anesthestics or adjuvants but hospitals without training program of residents used less commonly isoflurane, atracurium, midazolam, ketamine, propofol, fentanyl, cardiovascular drugs and pentastarch.

Renal artery embolization was induced experimentally in rabbits and microvascular changs were studiedangiographically, microangiographically and histopathologically. The results were as follows; 1. The mainmicroangiographic findings of renal artery embolization were arterial occlusion and collateral vessels arecharacterized by spiralling, dilatation, irregular lumen with abrupt caliber change, disoriented course andincreased number. 2. Collateral vessel formation was demonstrated in all cases of renal artery embolization bymicroangiography. 3. Recanalization of embolized vessels was better visualized by renal angiography thanmicorangiography. It was considered that microangiography is a valuable method for the observation ofmicrovascular changes in renal artery embolization and other renal diseases.

Teratomas, usually arising in the anerior mediastinum, are very uncommon in the posterior mediastinum. Embryologic development of anterior mediastinal teratoma is thought to be from thymic anlage which descends fromthe third branchial cleft and pouch, while that of posterior mediastinal teratoma is thought to be from the remnant of notochord. CT findings of posterior mediastinal teratomas are not different from teratomas elsewhere,containing fat, calcification, soft tissue and thick walled cyst. Ultrasonographic findings are mixed echogenicmass containing cystic portion, highly reflective solid portion and area of acoustic shadowing. Authors recently experienced 2 cases of surgically proven posterior mediastinal teratoma and report with review of literature.

BACKGROUND: Propioriacterium acnes plays an importantol in the development of inflammatory acne, and inflarnmatory lesions are improved by oralnc topical antibiotics. But as Pacnes frequently develop resistance to antibiotics in patients neing long term systemic antibiotic therapy, the theravuti effects diminish, and eventually thay fails. OBJECTIVE: The purpose of this study is to evaluate theerral susceptability of P. acnes to antibiotics and the difference in the MIC depending on the of oral and/or topical antibiotics, therapeutic effects and disease duration in patients with acie ulgaris. METHODS: We used twenty six strains of P. acnes which were obtained from patients with acne and performcd suseptibility testing for antibiotics usir the E test procedure. RESULTS: 1. The growth of P. acnes was completely inhibited by e ythromycin and chloramphenicol at concentrations of 0.023ug/ml and 0.064ug/ml, respectively cefoxitin at 0.094ug/ml, and by tetracycline and clindarnycin at 0.190 ug/ml. 2. P. acnes was mot susceptible to erythromycin, and olwed by chloramphenicol, cefoxitin, tetracycline, clindamycin in order of decreasing susceptibilit . 3. There were no significant differences in the MIC in reat in to previous antibiotic treatment. 4. For tetracycline, The MIC was significantly lower(p<0.01) in patients who improved after treatment. 5, For tetracycline and chloramphenicol, the MIC was grficantly lower(p<0.05) in patients with less than 2 years disease duration. CONCLUSION: The susptibility of antibiotics for P. acneias highest in erythromycin. There were no significant differences in the MIC in relation to prvious antibiotic treatment, and for some antibiotics the suseptibility was low in patients who dill not show clinical improvement or who had long disease duration.

PURPOSE: The purposes of this study were to analyze the MR findings of medulloblastoma, and to evaluate the subarachnoid dissemination and the significance of contrast enhanced MR of brain and spine for tumor.. MATERIALS AND METHODS: The preoperative brain MR studies of 18 patients (9 males, 9 females;mean age, 9.4 years) with surgically proved medulloblastomas were retrospectively reviewed to characterize these neoplasms with regard to their location, size, MR signal intensity, appearance after contrast enhancement, presence of cyst and necrosis, subarachnoid dissemination, and other associated findings. In 14 patients postoperative spine MR studies were evaluated for staging and therapeutic planning. RESULTS: The most frequent location of medulloblastoma was the inferior vermis and the mean tumor size was 4.1 x 3.6 x 3.9 cm. On Tl-weighted image, medulloblastomas generally had low to intermediate signal, predominantly hypointense relative to white matter. On T2-weighted image, medulloblastomas showed modetately high signal, hyperintense relative to white matter. Inhomogeneous contrast enhancement was demonstrated in 13 patients(72.2%) after injection of gadopentetate dimeglumine(Gadolinium). Cyst and necrosis within the tumor were visualized in 15 patients(83.3%). Subarachnoid disseminations of medulloblastomas were noted in 11 patients(61.1%), of which 6 demonstrated intracranial and 2 intraspinal dissemination. Three had both intracranial and intraspinal dissemination. In nine cases with intracranial lesions, there were intraparenchymal mass formation(7), subarachnoid nodules(5), infundibular lesions(2) and diffuse gyral enhancement(I). In five cases with intraspinal lesions, there were extramedullary intradural small nodules(3), central canal nodules(2), intradural masses(I)and fine nodular and sheet-like leptomeningeal enhancement(1). Other associated findings included intratumoral hemorrhage(11.1%), per/tumoral edema(44.4%), tonsillar herniation(44.4%), hydrocephalus(88.9%) and calcification(44.4%). CONCLUSION: Medulloblastomas revealed low to intermediate signal intensity on Tl-weighted image and intermediate to moderately high signal intensity on T2-weighted image, relative to cerebellar white matter. Medulloblastomas were solid tumors with cystic necrosis, which showed inhomogeneous enhancement and subarachnoid disseminations to the intracranial and intraspinal spaces after Gd-DTPA enhancement. Gd-enhanced MR of brain and spine was an useful diagnostic modality in preoperative diagnosis and in staging of postoperative cases of medulloblastomas, which was superior to postcontrast CT or precontrast MR.
