OBJECTIVE: To classify the findings of magnetic resonance imaging of the lumbar interspinous ligaments in relation to the lumbar disc herniation, disc degeneration, and lordosis. METHOD: The subjects were 45 herniated intervertebral disc(HIVD) patients and 35 normal subjects on MRI finding. The magnetic resonance features of the interspinous ligament were classified into five categories according to their signal intensities: type 1A (low intensity on T1- and T2- weighted images without hypertrophy of spinal process); type 1B (same signal pattern as in type 1A with hypertrophy of spinal process); type 2 (low intensity on T1- and high intensity on T2-weighted images); type 3 (high intensity on T1-weighted images); type 4 (others). RESULTS: The most common type in both HIVD patients and normal subjects was type 3. The mean age and disc degeneration grade of the type 1B ligaments were significantly higher. Lordosis of type 1B of L5-S1 interspinous ligament was increased with significant difference. CONCLUSION: The classification of the MRI findings of interspinous types didn't show statistical difference between HIVD patients and normal subjects, but was helpful in assessing the degree of the degeneration of the intervertebral disc and age.

OBJECTIVE: To investigate the relationship between the curvature of the cervical spine and various clinical parameters and to identify the validity of new curvature measurement methods. METHOD: The cervical spine curvature was assessed on lateral view of plain radiographs by three measurement indices. Index 1 is the ratio of length of line drawn by C2-C7 posteroinferior points and the longest length of vertical line to the posterior curve of C2-C7. Index 2 is the angle formed by three points of index 1. Index 3 is the sum of each distance from line drawn by C2-C7 posteroinferior point to C3-C7 posterior mid-points. The difference of each group and the relationship between pain scale and three indices were statistically analyzed by t-test and Pearson's correlation test. RESULTS: Sixty-three percent of control group patients showed a straight or kyphotic curvature and younger women group was more likely to have a straight curvature than other age groups. The newly designed measurement methods reflect the diagnostic significance of cervical curvature type measurement. Cervical lordosis did not exactly correlate with pain scale, symptom duration and the difference of clinical diagnosis. But the patients showing interval changes of pain scale were revealed the correlative change of curvature indices with each correlation coefficient of -0.43, -0.69 and -0.55 respectively. CONCLUSION: The altered cervical curvature is less valuable for the diagnostic significance and did not relate to the pain scale and duration, but cervical curvature reflect the interval change of the pain scale.

We have experienced 19 patients of the cerebral arteriovenous malformation with subarachnoid hemorrhage, who were admitted to the Presbyterian Hospital, Daegu from January 1966 to July 1968, and to the Catholic Medical Center, Seoul from August 1968 to August 1971. All of the patients, who have the cerebral arteriovenous malformation, were proved by cerebral angiography. Since the site of lesions were considered to have close relation to the neurologic deficit and the result of surgery, various analysis of the clinical manifestations and the cerebral angiographic findings were attempted. Of the 19 patients, surgery was performed on 12 patients and its results were analyzed correlating to various types of surgical procedure. Following are the results. 1. From January 1966 to August 1971, there were 100 cases of cerebral vascular anomalies which were proved by cerebral angiography. Among the 100 cases, there were 71 intracranial aneurysms, 19 cerebral arteriovenous malformations, one cavernous angioma, 2 telangiectasis, 5 cerebral rete mirabile, and s Sturge Weber-Dimitris disease. The ratio of arteriovenous malformatons to aneurysms was 1: 3.7. 2. Age distribution of the bleeding arteriovenous malformations was ranged from 8 to 54, and 42 per cent of them were in the third decade. 73 percent of the group had bleeding from the cerebral arteriovenous malformation before the age of 40. The ratio of male to female was 1.9:1. 3. The parietal region was most commonly involved by the malformations. There were 8 parietal lesion, 4 temoroparietal lesions, one temporal lesion, one occipital lesion, and one tela chorioidea lesion. Simultaneous involvement of the both hemispheres occurred in one case. In lesions involving the cerebral hemisphere, there was a predominance of the left side. 4. In the past history, convulsive seizure was recorded in two cases and recurrent hemorrhages were reported in two. One patient was recorded to have suffered fourth hemorrhage and the other have sufferd third hemorrhge. 5. Meningeal irritation signs were most frequently observed in bleeding arteriovenous malformations. The incidence of weakness of extremities was higher in lesions involving the parietal area. Unconsciousness was occurred in 6 patients at the onset of symptom, of which transient loss of consciousness was seen in 3 patients. Transient hypertension at the onset was observed in two patients. 6. The feeding arteries of the malformations were most frequently seen from the middle cerebral artery and the draining veins from the malformations were into the superior sagittal sinus and internal cerebral vein in many cases. It was evident that the carotid artery of the sites of arteriovenous malformations was markedly dilated in 5 patients. 7. Ligation of the vessels feeding the arteriovenous malformations was carried out in 8 patients. One patient had neurologic deficit after the operation. Evacuation of intracerebral hematoma, resection of the anomaly or carotid ligation were carried out in 4 patients. Of the 12 patients who underwent various types of surgery, there was one death after evacuation of a large intracereral hematoma. 8. In our opinion, the ligation of feeding artery a choice of procedure to reduce the incidence of rebleeding, if the resection of the lesion was considered to have operative risk by the location of malformations.

Chromosomally derived sterility has long been recognized. A review of the literature of somatic chromosome investigations in infertile males has shown that 13.7% of azoospermic males and 4.6% of oligozoospermic males have an abnormal karyotype. In the first group, sex chromosome abnormalities predominate (mainly 47,XXY), whereas in the latter, autosome anomalies (i.e. Robertsonian and reciprocal translocations) are the most frequent. A similar review on meiotic studies revealed that meiotic chromosome anomalies can explain male infertility in 4.3-40.4% of patients. Recently, fluorescent in-situ hybridization studies on spermatozoa from infertile men were published; it was suggested that both X-Y pairing and pairing of the autosomes were impaired, resulting in spermatogenic disruption. It is estimated that there are 2,000 genes that regulate spermatogenesis, most of these being present on the autosomes, but there are approximately 30 genes on the Y chromosome. In general, autosomal genes that regulate spermatogenesis are concerned with regulation of metabolic processes in other cells in the body as well as in the cells of spermatogenesis, whereas Y genes are not essential for vital functions related to reproduction. To be able to provide proper counseling for those couples whose male infertility can now be treated by intracytoplasmic sperm injection, it is suggested that clinical investigations should include mitotic and meiotic studies, an analysis of the chromosome content of individual spermatozoa and a DNA analysis of blood and spermatozoa to detect partially deleted Y chromosome material. We have experienced a case of azoospermia associated with inversion of chromosome 1. So we report this case with a brief review of literatures.

OBJECTIVE: In these retrospective studies, the authors report an evaluation of clinical and radiological outcome in patients with cervical spine injury who underwent anterior cervical fusion with Caspar Plating system. METHODS: The authors studied 45 patients with unstable cervical spine after trauma between July 1996 and December 2001. Our series consist of 39 male and 6 female. The cervical spine injury was most common in men in fourth decade. Motor vehicle accidents were a frequent cause of cervical spine injury. Thirty-three patients had fractures with instablity, ten a ligamental injury without fracture, one traumatic hernated disc. Lateral cervical spine X-rays were reviewed for evaluation of fusion and instrumentation failure. RESULTS: In most cases, operation for stabilization was done around one weeks after trauma. In all patients excellent immediate postoperative stability of the spine was obtained, although posterior fusion was necessary at same time in one patient. Solid fusion was achieved in all except two patients who died during the first 2 months after the operation. Three patients developed instrumentation related failure(6.7%): Two patients had screw loosening, one infection. Two of these patients underwent reoperation. The most dreaded complication of dural or cord penetration by drilling or screw placement was not observed. There was no postoperative neurological disturbances. Four patients died of causes unrelated to operation: Two patients died of upper gasterointestinal bleeding, and the other two died of pneumonia and sepsis respectively. CONCLUSION: The Caspar plating system affords an effective means of improving the fusion rate with acceptable instrumentaton-related morbidity in cervical spine injury.

OBJECTIVE: The purpose of this study was to analyze the clinical study for patients with cervical cancer who had undergone radical hysterectomy. METHOD: The subjects of this study were one hundred and sixty two patients with cervical cancer who had undergone radical hysterectomy at Eulji Medical College Hospital, Taejon, Korea, from January 1983 to December 1992. We reviewed the medical record retrospectively and analyzed the data. RESULT: The distribution of patients by age was found in the order of 50 decade and 60 decade, 40 decade. Those by the clinical stages were as follows: Stage Ia, 12 cases(7.4%); Stage Ib, 84 cases(51.9%); Stage IIa, 39 cases(24.1%); Stage IIb 27 cases(16.7%). The results of histopathologic type were distributed as follows: squamous cell carcinoma was 91.9%, adenocarcinoma was 4.9% and adenosquamous cell carcinoma was 3.1%. The histologic subtypes of squamous cell carcinoma(149 cases) were as follows: Large cell non-keratinizing type was 75.9%, large cell keratinizing type was 14.8% and small cell type was 1.2%. The frequancy of lymph node metastasis was 22.9% in stage I and 31.8% in stage II. The overall incidence of lymph node metastasis was 26.4%. The frequency of external radiation therapy done after radical hysterectomy was 63.5% in stage I and 75.8% in stage II. The 5-year survival rate was as follows: The Ia was 100%; Stage Ib, 95.2%(4cases); Stage IIa, 87.2%(5cases); Stage IIb, 77.8%(6cases). The incidence of recurrence was 7.4% and recurrent sites were vaginal stump , rectum and pelvic wall. CONCLUSION: The highest incidence of cervix cancer in age distribution was 50 decade(30.9%) and 60 decade(30.9%). The most common clinical stage was Ib(51.9%) and most frequent pathologic type was squamous cell carcinoma(91.9%). The overall incidence of lymph node metastasis was 26.4% and The most common site of recurrence was vaginal stump. The 5-year survival rate was 100% in the stage Ia, 95.2% in the stage Ib, 87.2% in the stage IIa, 77.8% in the stage IIb.

An experiment was planned to observe the histopathological alteration with administration of the Rheomacrodex and blood pressure changes in induced cerebral infarct after occlusion. Eighty well developed cats, weighing 2.3 to 3.5kg, were used in this experiment. The right MCA was exposed through temporal approach and the proximal part of the MCA was occluded with a silver clip. The animals were divided into 4 groups: The control group was comprised of 20 cats with occlusion of the right MCA alone, Rheomacrodex-treated group was comprised of 20 cats after occlusion of right MCA, induced hypotension and hypertension groups consisted in each 20 cats following occlusion of the MCA. The animals were sacrificed at intervals of 3 hours, 6 hours, 24 hours, 1 week and 2 weeks respectively after occlusion of the MCA. The animals were studied for clinical deficits and histopathological changes of the cerebral infarct according to the time courses. The results obtained were as follows: 1) In the control group, severe contralateral hemiplegia was developed in the early stage following the MCA occlusion, however the neurological deficits were progressively improved to the state of abnormal walking in 24 hours to 2 weeks. The hemorrhagic infarct was involving the basal ganglia, internal capsule and extending to the cortex with mild brain edema in the early stage and the area of the infarct was gradually enlarged from 6 hours to 24 hours following the MCA occlusion. Although the brain edema of surrounding area of the lesion was remained unchanged, the size and distribution of the infarct were decreased in one week to 2 weeks. Extensive ischemic neuronal damage was observed in the control group. 2) In the Rheomacrodex-treated group, mild to moderate neurological deficit was developed in the early stage after MCA occlusion and the deficit was less severe than control group. The clinical deficit was improving in the time course and one case had shown completely normal activity in 2 weeks. The distribution of the infarct was well defined and it was smaller than control group. The infarct mainly involved the basal ganglia and internal capsule. The area of the infarct was gradually enlarged from 6 hours to one week after MCA occlusion, then the extent of the infarct was decreased in 2 weeks. The ischemic neuronal change in this group was less severe than control group. 3) In the induced hypotension group, the early neurological deficit was worse than that of the control group and severe hemiplegia was developed in one week. There was minimal improvement of the neurological deficit in 2 weeks. The area of the infarct was ill-defined and hemorrhagic extending a large portion of the brain with severe brain edema. The infart was involving the basal ganglia, internal capsule, claustrum and the cortex from 3 hours to 24 hours after the occlusion and the area of the infarct was not changed during the observation. Severe ischemic nerve cell change or resolution of the cells was oserved in this group. 4) In the induced hypertension group, the neurological deficit was mild and it was better than that of the control group. The distribution of the infarct was well localized and minimum in extent. The extent of the infarct was not changed during the observation. There was no observable gross brain edema and the ischemic nerve cell changes were not severe.

BACKGROUND: Generalized lichen nitidus is a rare subtype of lichen nitidus characterized by multiple, flesh-colored, shiny papules occurring over the entire body. OBJECTIVE: We investigated the clinical features of generalized lichen nitidus in patients followed up at our institution. METHODS: The patients with generalized lichen nitidus diagnosed clinically and histopathologically between 1998 and 2007 were reviewed. RESULTS: Twelve patients (9 males and 3 females) were enrolled in this study and the mean age at onset was 10.3 (range: 4~27) years. Of the 12 patients, 5 (41.7%) experienced pruritus and 4 (33.3%) had atopic dermatitis. None of the patients had a family history of lichen nitidus. Nine patients were treated with topical steroids, systemic steroids, oral antihistamines, or narrow-band UVB. We propose that narrow band UVB is an effective treatment modality for generalized lichen nitidus. The mean duration to clearance was 37.7 (range: 7~120) months and the disease was relapsing in 2 patients. The duration to clearance was correlated to the age at onset (p=0.0005) and to the duration at the first visit (p=0.0000), whereas it was not related to the sex of the patient, pruritus or the accompanying atopic dermatitis. CONCLUSION: Generalized lichen nitidus is often associated with varying degrees of pruritus and the clinical course of the disease tends to be chronic. We propose that onset at an early age and the short duration of disease at the first visit are good prognostic factors, and that narrow band UVB is an effective treatment modality for generalized lichen nitidus.

OBJECTIVE: To survey the prevalence of cumulative trauma disorders (CTDs) and to analyze the ergonomic factors in the paper reviewing workers. METHOD: Five hundreds and twenty subjects of paper reviewers were collected from 'National Medical Insurance Association' who had been exposed to risky working environment regarding CTDs. The subjects were first screened by occupational medicine specialists and confirmed by physiatrist. The subjects were also examined by serologic test, radiologic imaging, and electro diagnostic study. Ergonomists analyzed the job element to identify the risk factors by baseline checklist of CTDs. RESULTS: Among the workers, 51 (9.8%) of 520 were confirmed to CTDs, the prevalance of myofascial pain syndrome was 22 (43.1%), that of medial epicondylitis was 13 (25.5)%, lateral epicondylitis 8 (15.7%) and others. Pain scale of National Industrial Occupational Safety Health Institute symtoms criteria was highest in the shoulder girdle and the next was in the neck, in the wirst and fingers. The ergonomic risk score was highest 2.56 in the 'verifying' job, and the next 2.20 in 'the 2nd examination' job and 'the 1st examination' job, 1.72 in 'correcting' job. CONCLUSION: The result would be helpful for the prevention and management of CTDs in the paper reviewing workers.
