To understand the mode of transmission in clonorchiasis, a survey was made in Kim-hae Goon, South Kyong-sang Do (=Province). The mathematical analysis of the age prevalence was done on the egg positive rates. And another analysis for the comparison was also made to the cited data from two areas, North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do. Some catalytic models of H. Muench (1959) were applied to the observed age prevalence. Because the both parameters, such as force of infection(a) and loss of positivity(b) were considered to be constant for a long period in the surveyed area, the two stage catalytic model by Muench was chosen to the analysis. In the surveyed area, Kim-hae Goon where the egg positive rates were 56.2 percent and 61.2 percent (by Kim, 1974), the constant values of 'a' were found to be 0.051 and 0.089 respectively. In other words, the force of infection was 51, 89 per 1,000 susceptibles. The values of 'b' were found to be 0.006 and 0.005. This means that the rates of disappearance from egg positive cases to negative were 6 and 5 per annum per l,000 positive cases in above area. Therefore, the two catalytic curves were expressed by the following equations, y = 1.133 {e(-0.006t) - e(-0.051t)} and y = 1.047 {e(-0.005t) - e(-0.089t)} respectively. In the cases of North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do where the egg positive rates of clonorchis shown as 27.7 percent and 15.2 percent by Shin (1964) and Kim (l974), the curves were expressed by y = 1.769 {e(-0.010t) - e(-0.034t)} and y = 2.857 {e(-0.020t) - e(-0.027t)} respectively. From the above mathematical analyses by age prevalence in clonorchiasis, it was considered that the mode of transmission of clonorchiasis in the surveyed area, Kim-hae Goon presented more rapid pattern than those of North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do.

This is a retrospective review of 11patients of type II SLAP lesion which were found during arthroscopic treatment of 26 patients diagnosed SLAP lesion, clinically and radiologically, hetween March l989 and June 1996. Follow-up time was averaged 26 months (range, l2 months to 72 months) and average age was 30 years old. All patients were treated arthroscopically for SLAP lesion. In type II 2 cases were repaired hy biodegradable tacks (Suretac(R)), 9 cases were repaired by transglenoid and transscapular tcchnique that included dehridement of the frayed lahrum and ahrasion of the superior glenoid neck, followed hy the placement of multiple suture on the torn capsular-labrum complex and lahrum-biccps tendon complex using suture hook, heath pin and # 0 PDS (Rhee's method). Among 9 cases with transglenoid and transscapular suture technique in type II SLAP lesion, the result were quantitated with Rowe ratin scale, 4 cases were exellent, 3 cases were good and 2 cases were fair. Our modification technique, using transglenoidal two bone hole technique and tying on scapular spine can ohtain as compatible fixation as other techniques which include metal staple, bioderadahle tacks (Suretac(R)) and anterior anchoring system such as mini-Revo. Our technique also has reasonable recurrence rate with few complication. The advantage of our modified technique is able to do superior capsular advancement, capsular plication and capsular shift which procedures are very difficult in other techniques. We propose arthroscopic transglenoid and transscapular suture technique (Rhee's method) for type II SLAP lesion as one of new method of suture for type II SLAP lesion.

Journal of Korean Neurosurgical Society 1977;6(1):93-102
Spontaneous cerebellar hemorrhage is classically considered a rare and fatal disease because the early diagnosis is very rarely made during the life, and there is scant mention of the problems of spontaneous hemorrhage into the cerebellar hemisphere. However our opinions indicate that its frequency is greater than is generally thought although it is considered a rare lesion. The purpose of this paper is to record our present opinions concerning the possible early diagnosis and surgical management of the spontaneous cerebellar hemorrhage. We believe that it is possible by clinical examination alone to make or strongly suspect the diagnosis in life during the early stage before irreversible damage occurs and that emergency surgical intervention is strongly indicated. The patients is a 38 year old man admitted to the Department of Neurosurgery, Catholic Medical Center on Nov 3, 1976 with severe headache, vomiting, dysarthria and mental confusion. On examination, he was disclosed mental confusion, repeated vomiting, constricred pupil, horizontal nystagmus, inability to stand, dysarthria and neck stiffness. We confirmed the diagnosis under the cerebellar hemorrhage involving the cerebellar vermis and both cerebellar hemispheres by means of vertebral and carotid angiography, conray ventriculography, and cerebrospinal fluid examination. We underwent suboccipital craniectomy with the evacuation of hematoma at the vermis and both cerebellar hemispheres after 48 hours of onset of illness and his postoperative course was good except for mild cerebellar dysfunction signs and he was discharged on 45th hospital days.

Hemorrhagic fever with renal syndrome (HIFRS), scrub typhus, murine typhus and leptospirosis have been the principal acute febrile diseases in Korea. To evaluate the seroepidemiologic patterns of acute febrile illness, sera collected from 2,423 patients in 1996 were examined for antibodies against Hantaan virus, Orientia tsutsugamushi, Rickettsia typhi, and Borrelia burgdorferi by indirect immunofluorescent antibody technique (IFA) and macroscopic agglutination test for Leptospira interogans. Seropositive cases against O. tsutsugamushi, Rickettsia typhi, Leptispira interogans and Hantaan virus were 192 (7.9%), 193 (8.0%), 12 (0.5%) and 324 (13.4%), respectively. Male was more affected in HFRS and murine typhus contrasting to scrub typhus and leptospirosis in female. Most positive cases occurred during October and November for scrub typhus, and during November and December for HFRS. These results showed similar patterns with previous epidemical data for recent couple of years, and possibly implied no significant changes occurred in ecologic situations for acute febrile diseases in Korea.

From September 1987 to June 1994, the authors had performed posterolateral fusion in one patient, anterior spinal fusion alone in four patients, anterior spinal fusion after posterior augmentation with Rectangle Luque and posterolateral fusion in four patients of tuberculosis of the lumbosacral junction. The purpose of this study was evaluated the reliability of the posterior augmentation with Rectangle Luque and posterolateral fusion. We divided into two groups: the study group was anterior spinal fusion after posterior augmentation with Rectangle Luque in four patients, the control group was anterior spinal fusion alone in four patients. The average follow up was obtained at 16 months(12 to 20 months) in study group, at 42.7 months in control group. Results were as follows: 1. Clinical results according to Moskowitz criteria were 2 patients with grade I. 2 patients with grade II in the study group; one patient with grade I, one patient with grade II, one patient with grade III, one patient with grade IV in the control group. Hypolordosis(less than 10 degree) at the lumbosacral junction was associated with a higher incidence of back pain. 2. Radiographically well consolidated anterior fusion was noted in all patients within average 6 months (5-7 months) in the study group and 7.2 months (5-10 months) in the control group. 3. Radiologically the lumbosacral saggital angle was corrected after operation and the mean angle was 16.5 degrees(12 to 20 degrees) in the study group, 7.2 degrees(3 to 20 degrees) in the control group. The mean loss of angular correction was 5 degrees(1 to 8 degrees) in the study group, 6.2 degrees(1 to 13 degrees) in the control group at postoperative one year follow up. In conclusion, this results suggest that the anterior spinal fusion concomitant with the posterior augmentation with Rectangle Luque is the recommendable methods for tuberculosis of the lumbosacral junction in adults.

Hantaviruses are distributed in rodent population world-widely even in geographical areas where hemorrhagic fever with renal syndrome (HFRS) has not been reported. Va.ictus species of Family Muridae and Arvicolidae serve as the natural reservoirs of hantaviruses. Hantaan virus, Seoul virus, Puumala virus, Prospect Hll virus, Sin Hombre virus and New York virus are members of genus Hantavirus and isolated from lungs of A. agrarius, C glareolus, M. pennsylvanicus, P. maniculatus and P. leucopus respectively. This experiment was intended to find the distribution of hantavirus infection among wild rodents and isolate the hantavirus from lung tissue of seropositve Apodemus peninsulae, and compared the nucleotide and amino acid sequences with prototype of hantaan virus 76-118 strain. Hantaviral sequences were amplified from lung tissues of A. peninsulae by reverse-transcriptase polymerase chain reaction. Alignment and comparison of the 324 nucleotide of G2 region of M-genomic segment diverged 4.6% and 0% at the nucleotide and amino acid levels, and complete N protein-coding region of S-genomic segment diverged 3.7% and 1.4% nucleotide and amino acid levels, respectively. This is the report to spill-over on the hantaan virus from A. peninsulae to A. peninsulae in Korea.

Primary aldosteronism, characterized by hypertension, hypokalemia, and hyperaldosteronemia resulting from chronic oversecretion of aldosterone independent of normal renin-angiotensin regulatory system, is due mostly to aldosteronoma or to bilateral cortical nodular hyperplasia. We report two cases of primary aldosteronism due to adrenal cortical adenoma, which were diagnosed by clinical data and abdominal computed tomographic scan. Clinical symptoms and laboratory data returned to normal after surgical adrenalectomy.

We have experienced 109 cases of hypertensive intracerebral hemorrhage admitted to the Department of Neurosurgery of Catholic Medical Center from January 1973 to August 1976. We analized the result of treatment of hypertensive intracerebral hemorrhage and assessed prognostic factors affecting the results of surgical treatment of hypertensive intracerebral hemorrhage. 1. The age of the patients did not significantly influence on the mortality of operative or non-operative cases provided the age is below sixty. 2. The amount of hematoma did not directly related to the outcome of operated cases if the hematoma is less than 50ml, while the mortality was considerably increased if the clot was more than 50ml. 3. There was no specific difference in operative mortality between total evacuation and partial evacuation of hematoma in surgery of the hypertensive intracerebral hemorrhage, but total evacuation had better result than that of partial evacuation in the functional recovery. 4. The operative mortality of the hypertensive intracerebral hemorrhage was 43.6% and 55.7% in non-operative cases. Thalamic hemorrhage carried the highest mortality either operated or conservatively treated. 5. The surgical treatment carried better result than non-operative treatment in the case showing progressive change in consciousness following intracerebral hemorrhage. Conservative treatment obtained good result in the cases showed progressive improvement of conscious level following intracerebral hemorrhage. 6. The interval from the ictus to surgical intervention did not constantly influence on the result of surgery and it might be wise to decide the time of surgical intervention according to the progressive changes in conscious level and neurological status after bleeding. 7. The operative result was favorable in the patients who has shown progressive worsening of conscious level and neurologic status following clear conscious at hemorrhage (class II). We also noted that the patients were unconscious at ictus then became progressively stupor with increasing neurologic deficit showed better result with surgical treatment than non-operative care.
