Tumors of the central nervous system are the second most frequent neoplasm in children. In a review of 43 children with brain tumor under the age of 16 evaluated at a pediatric and neurosurgical department at Severance Hospital Yonsei University during a 61/2 year period, following results were obtained. 1. All 43 cases were diagnosed by pathological examination as well as brain CT scan. The sex ratio of male and female was equal. The age distribution was highest between 13-14 year of age and 7% of them were under 1 year of age. 2. There was a small preponderance of infratentorial tumors (51%) over supratentoral tumors (49%). 3. Among 43 verified brain tumors by pathological examination, glioma represented 75%, of which astrocytoma was the commonest neoplasm being 19 cases (45%) and remainder were medulloblastoma 10 cases (23%), choroid plexus droglioma 2 cases (5%), ependymoma 1case (2%). The rest were craniopharyngioma 6 cases (14%), choroid plexus papilloma 1 case (2%), neuroblastoma 2 cases (5%), pineal teratoma 1 case (2%), melanotic neuroectodermal turmor 1 case (2%). 4. The most common symptom was headache occuring 63% of the patients followed by vomiting, motor weakness, visual disturbance, gait distrubance, mental disturbance and seizure in order of trequency. Neurological signs showed positive Babinski sign, papilledema, cerebellar sign, 6th nerve palsy and facial weakness. 5. Plain skull X-ray changes were noted in 26 out of the 43 cases (61%). Those were suture separation of skull noted 35% of tumors followed in frequency by increased digital marking, sella changes and calcification. 6. In brain CT scan studies, the most common abnormal finding was solid mass shadow followed by cystic mass shadow, solid and cystic mass shadow. After contrast infusion, diffuse enhancement was the most common features. 7. 27 cases were treated by operation only, 15 by operation and radiotherapy, 1 by operation, radiation and chemotherapy. 8. Progonsis of brain tumor was very poor. 5 of 43 cases died within 1 month of diagnosis, 1 year survival rate was 19%, and 2 year survival rate was 16%. The survival rate was better in the group of patients in whom total or subtotal resection combined with radiotherapy was performed. 53% of cases were not able to follow-up or discharged anainst advice without proper treatment.

This study examined burdens of primary family carcgivcrs of paticnto with cerebrovascular accidents (CVA) along with related factors. In addition, their needs for support group intervention were assessed to develop a support group to reduce the burdens of caregiving. Eighty-one primary family caregivers of patients with CVAs at a general hospital in Seoul participated in this study . The patients with CVAs aged from 26 to 83 years with mean age of 63 years. About 90% of the patients had some paralysis and 56.6% suffered speech problems. Fifty-eight percent of the primary family caregivers were spouses of the patients and 80.2% were women. Primary family caregivers' burdens were assessed by the Burden Scale originally devel oped by Zarit (1980) and Novak & Geust(1989) and modified by Jang (1995) for use in Korea. The instrument consists of six subscales time-dependent burden, developmental burden, physical burden, emotional burden, social burden, and financiaI burden. The results were as follows : 1. The average of burden score was 91.7, indicating moderate to severe level of burden. The time-dependent burden was scored highest followed by physical, developmental, social, financial, and emotional burdens. 2. of the characteristics of patients, age, gender, and severity of the disease were found to be associated with the level of burden. Of the characteristics of primary family caregivers, age and educational level were significantly related to the level of burden. Time of care since the CVA and the quality of relationship between a patient and a caregiver prior to the stroke were significant situational factors affecting the level of burden. 3. The need for support group intervention for the caregivero was very high (95.1%). The earcgivcrs of patients who had a CVA for the first time showed higher levels of need compared to those of patients who had a CVA more than once. The caregivers indicated a support group held once a month near home or hospital would be welcomed. In addition, they replied that a group composed of 9 to 10 caregivers and guided by health care professionals (e.g., physicians and nurses) would be most desirable. More than 85% of the earegivers identified the areas that they wanted intervention in as follows : knowledge, skills, and resources to care for a patient with a CVA. the counsel of health care professionals, share of their experiences with those who have similar situations, stress management skills, and methods to overcome emotional isolation due to the great responsibility for a patient. Given the results, support group is expected to be an effective way to reduce the burdens of primary family caregivers of patients with CVAs. As a follow up It is necessary to examine the effect of support group intervention on the patient's recovery and rehabilitation.

Mitochondrial DNA (mt DNA) and the non-recombining region of the Y chromosome are passed down, unaltered, from generation to generation, matrilineally and patrilineally, respectively. Therefore, the Y-chromosome DNA and mtDNA are known as lineage markers, and they play important roles in studies based on human migration and evolutionary history. Y-chromosome DNA is used in forensic analysis to identify individuals involved in cases of sexual assault. In this paper, we review the methods of statistical evaluation of lineage markers used in forensic identification. We also review the combined approach of autosomal and lineage marker evidence.

OBJECTIVE: This study was conducted to provide a nationwide analysis on barriers to cervical cancer screening in Korea. METHODS: Data used for this study was obtained in a survey called Korean National Health and Nutrition Examination Survey (KNHANES) 2005, which collected data from 2,590 Korean women aged older than 21 years who had not had a hysterectomy and were eligible for Papanicolaou (Pap) smears. Multivariate analysis was adopted to control each demographic factor and unhealthy behavior variable. Demographic factors included age, education, income, job and region; health-related behavior factors were defined as current smoking, obesity, hormone replacement therapy and disability. RESULTS: The study found that cervical cancer screening rate was significantly positively associated with income (odds ratio [OR], 1.002; 95% confidence interval [CI], 1.001 to 1.002), with education (OR, 1.324; 95% CI, 1.030 to 1.703), with job (OR, 1.420; 95% CI, 1.030 to 1.957), and with hormone replacement therapy (OR, 3.732; 95% CI, 2.354 to 5.916). Meanwhile, the age (OR, 0.977; 95% CI, 0.968 to 0.985), disability (OR, 0.358; 95% CI, 0.143 to 0.894) and smoking (OR, 0.447; 95% CI, 0.280 to 0.715) were significantly negatively associated with one's chances to take cervical cytology. CONCLUSION: In order to increase the rates of Korean women taking Pap test, cervical cancer screening programs will have to pay special attention to the elderly, low-income group, smokers, and the disabled.

PURPOSE: Upper urinary tract diseases are major factors increasing morbidity and mortality in patients with spinal cord injuries. A video urodynamic study is one of the best methods for detecting neuro-urologic functional impairment in such patients. Therefore, the risk factors of upper urinary tract diseases were evaluated in patients with a spinal cord injury undergoing video urodynamics. MATERIALS AND METHODS: The subjects were 161 spinal cord injured patients with voiding difficulty. The patients were divided into 2 groups, on the basis of the presence of upper urinary tract diseases, and compared according to various objective factors. In addition, the neurogenic bladder dysfunction was classified according to the anatomical level of the spinal cord injury. RESULTS: Of the 161 patients, 13 developed upper urinary tract diseases. When those patients with and without upper urinary tract diseases (complicated and normal groups, respectively) were compared, the rates of patients with chronic urethral or suprapubic catheterization, upper motor neuron injury, quadriplegia, complete injury and low compliance were higher in the complicated than the normal group. There was also an increasing rate of the prevalence of detrusor areflexia in lower motor neuron lesions. The patients with detrusor hyperreflexia, accompanied by detrusor-sphincter dyssynergia, mostly had a cervical cord injury. CONCLUSIONS: Chronic urethral or suprapubic catheterization, upper motor neuron injury, complete injury with quadriplegia, and low compliance are thought to be risk factors for inducing upper tract diseases in spinal cord injury patients. Thus, patients exposed to these factors should be monitored through video urodynamics and radiologic evaluation for the prevention and early detection of upper urinary tract diseases.

PURPOSE:To compare macular thickness and visual acuity before and after panretinal photocoagulation in patients with severe diabetic retinopathy without diabetic macular edema. METHODS: Macular thickness and visual acuity (LogMAR) of 40 eyes were compared before and after panretinal photocoagulation, for severe diabetic retinopathy. Macular thickness was measured by optical coherence tomography(OCT). In addition, changes in macular thickness and visual acuity were compared with the patient's level of HbA1c, blood pressure, and diabetic nephropathy. RESULTS: Mean visual acuity before and 1.47+/-0.80 months after panretinal photocoagulation were 0.28+/-0.23 and 0.33+/-0.27, respectively, which was not a significant decrease (p=0.131). However mean central macular thickness (216.98+/-34.09 microm to 255.22+/-73.40 microm), and mean peripheral macular thickness (269.26+/-34.59 microm to 291.96+/-46.49 microm) did increase significantly after panretinal photocoagulation (p=0.001). The decrease of mean visual acuity and increase of mean macular thickness were greater in patients with high blood glucose, high blood pressure and diabetic nephropathy. CONCLUSIONS: In eyes with severe diabetic retinopathy treated with panretinal photocoagulation, mean visual acuity did not decrease significantly, but mean central and peripheral macular thickness significantly increased after treatment. We posit that visual prognosis after panretinal photocoagulation in eyes with severe diabetic retinopathy without macular edema is influenced by the control of blood glucose and blood pressure and the presence of diabetic nephropathy.

We report a rare case of multicentric Castleman's disease that presented with ophthalmic involvement, along with a review of the literature. A 63-year-old male presented with decreased visual acuity in both eyes. Both eyes had serous elevations of the retinas with shifting subretinal fluid and annular choroidal detachment. No retinal breaks were found. Laboratory tests revealed pancytopenia, hypergammaglobulinemia, and an increased erythrocyte sedimentation rate. Chest and abdominal computed tomographies showed multiple lymphadenopathies in the mediastinum, abdomen, and in both inguinal areas. Histological examination of the inguinal lymph node biopsy was consistent with Castleman's disease. After combination chemotherapy, the serous elevations of both retinas and the annular choroidal detachments of both eyes disappeared. Ophthalmic involvement in Castleman's disease is very rare, and to the authors' knowledge, this is the first report of ophthalmic involvement of Castlemans's disease in Korea.
