OBJECTIVE: To examine the association between age at menopause and mortality in a population-based sample of women in Kangwha, Korea. METHODS: From the Kangwha Cohort, followed-up from 1985 to 1999, the data of the over 55 year old female group(n=3,596) was used in this study to examine the association between age at menopause and mortality. We calculated the all causes mortality risk ratio and the cancer mortality risk ratio by age at menopause grouping using the Cox Proportional Hazards Model with adjustments for age, BMI, smoking, education, chronic disease, self-rated health status, alcohol consumption and age at first birth. RESULT AND CONCLUSION: Compared to women who had menopause at 45-49 years, the all causes mortality risk ratio was 1.24 for women with menopause at less than 40 years(95% CI=1.01-1.53) and 1.05 for women with menopause at over 50 years(95% CI=0.92-1.20). Also, compared to women who had menopause at 45-49 years, the cancer mortality risk ratio was 1.53 for women with menopause at less than 40 years(95% CI=0.78-2.98) and 1.17 for women with menopause at over 50 years(95% CI=0.77-1.80).

When the skin and soft tissue necrosis occurs due to extravasation of intravenously administrated biological active materials and drugs, no specific mode of treatment modality is known except for supportive management or debridement and skin graft. This experiment was designed to determine the effective dosage of hyaluronidase and triamcinolone acetonide on the extravasation necrosis caused by calcium gluconate and to establish the optimal time of administration of the antidotes. Initially 0.4 ml of 10% calcium gluconate was injected subcutaneously into the rabbit back. Study I was designed to observe the skin change in 8 groups including control group with no treatment and treated groups with normal saline, saline with hyaluronidase(dosage: 150, 300, 600 unit), saline with triamcinolone acetonide(1 mg, 2 mg), and 150 unit hyaluronidase and 1 mg triamcinolone acetonide (all in volume 0.2 ml, treatment delay: immediate, 15-minutes, 30-minutes, 1-hour, 3-hours delay). The sizes of skin necrosis and induration were measured and compared between each group. Study II was designed to examine the histologic findings of the skin and evaluate the effect of hyaluronidase and triamcinolone acetonide on tissue damage. The sizes of induration and necrosis are smaller in all treated groups than non-treated group and the statistically significant protective effect on reducing the size of necrosis was found in groups treated with the drugs within 15 minutes to 30 minutes(p < 0.05). The most effective protection was obtained by the immediate injection of 150 unit dosage of hyaluronidase with 1 mg triamcinolone acetonide. This study suggests that intralesional injection of hyaluronidase and triamcinolone acetonide within half hour delay for the treatment of extravasation necrosis of calcium gluconate is the most effective, probably due to their diffusion, antiinflammatory effect and role in facilitating the resorption of calcium in the tissue.

Brown-Séquard-plus syndrome is characterized by hemiparesis, contralateral spinothalamic sensory deficits with additional abnormal findings of other organs. We report a case of an 81-year-old man who had right hemiparesis, left sensory deficit and Horner syndrome on right eye. Diffusion-weighted MRI of the cervical spine and lower medulla confirm the diagnosis of anterior unilateral cervical spinal cord infarction. It is very rare that the unilateral long spinal cord infarction at the C1-C4 associated with Brown-Séquard-plus syndrome.

BACKGROUND AND PURPOSE: Recently published, evidence-based guidelines should alter the management of amyotrophic lateral sclerosis (ALS)/motor neuron disease (MND). However, the newest recommendations for ALS/MND therapy are not reflected in actual clinical practice. We sought to evaluate the current status of the diagnosis and management of ALS in Korea. METHODS: The Korean ALS/MND research group was organized in 2010, involving more than 50 neurologists from neuromuscular centers in Korea. Participating centers collected data from April to September 2010 on the diagnosis and management of patients with ALS. Data forms from the ALS patient care database, which is a component of the ALS clinical assessment, research, and education program (http://www.outcomes-umassmed.org/ALS/), were modified and used for data collection. RESULTS: In total, 373 sporadic ALS cases from 35 centers were enrolled. The demographic features and clinical findings were similar to those in previous reports from other countries. The mean age at onset was 50-60 years, and a slight male predominance was observed. The enrolled patients predominantly showed focal onset of cervical or lumbosacral symptoms. Only about one-half of the indicated patients (31.4%) received a physician's recommendation for a parenteral gastrostomy, and 18.1% underwent the procedure. Noninvasive ventilation was recommended in 23% of patients, but applied in only 9.5% of them. Tracheostomy was performed in 12.7% of patients. CONCLUSIONS: The demographic and clinical features of the diagnosis and management of ALS in Korea are similar to those reported in other countries; however, supportive management, as recommended in evidence-based guidelines, are not yet widely recommended or performed for patients with ALS in Korea.

Neurofibromatosis type 1 (NF1) is an autosomal dominant disease characterized by neurological, cutaneous, and ophthalmological manifestations. A 33-year-old woman with typical symptoms of NF1 visited Ajou University Hospital. Screening of the whole-messenger RNA region of NF1 at the complementary DNA level by polymerase chain reaction-direct sequencing confirmed the presence of an NF1 mutation at the genomic level. The mutation analysis revealed an in-frame skipping of exon 46 (c.6757_6858del) caused by a point mutation (c. 6792C>A) in exon 46. In this report, we have described the first Korean case of a proband with NF1 that carries an allele with an exon 46 deletion caused by an exonic splicing enhancer site mutation, leading to the skipping of the whole of exon 46 (c.6757_6858del).

OBJECTIVES: This research was performed in order to develop the social perception scale which could detect the deficits of the social perception, composed of visual perception and contextual perception, in the patients with schizophrenia and might have the desirable reliability and discriminating power between the patients with schizophrenia and the normal controls, and so as to be appropriate to the schizophrenics' cognitive rehabilitation strategy of Brenner, et al. METHODS: We selected 10 photographs among 30 photographs which could show the variable social situations according to the consensus of the staff members of the Integrated Psychological Therapy. Then we developed the questions, composed of visual perception subscale and contextual perception subscale, which we called preliminary social perception scale. We tested the above scale to the 20 patients with schizophrenia in the chronic mental hospital. Then we tested the above scale to both the 20 patients meeting DSM-IV criteria for schizophrenia in the closed ward of the university psychiatric hospital and the 20 normal controls. We developed the final social perception scale to exclude the items of inadequate reliability. We compared the item difficulties of social perception scale between the patients in the chronic mental hospital and those in the university psychiatric hospital. finally, we compared the scores of social perception scale between the patients with schizophrenia and the normal controls. RESULTS: The final 6 items were selected to become the social perception scale according to the values of the item-total correlation, test-retest reliability, and interrater reliability. The final social perception scale showed similar rank of item difficulties between two groups with schizophrenia. The patient group differed significantly fiom the normal control group on the scores of contextual perception subscale(t=-3.09, p<.01) and the total scores of social perception scale(t= -3.33, p<.01). CONCLUSION: This study suggests that the above social perception scale which has excellent internal consistency, test-retest reliability, interrater reliability and the discriminating power. This scale can be applied to both the cognitive rehabilitation strategy in the patients with schizophrenia and the evaluation of the effectiveness of the cognitive rehabilitation.

PURPOSE: To evaluate the changes in penile sensitivity during the erectile response and their role in premature ejaculation, We investigated the penile sensitivity of patients with premature ejaculation or impotence and normal volunteers. PATIENTS AND METHODS: Penile sensitivity was evaluated by vibratory threshold in 19 men with premature ejaculation (PE group; average age 37.8 years), 14 men with impotence (Impo group; 41.8 years), and 13 normally potent male volunteers (control group; 30.0 years). Vibratory thresholds were recorded three times at the glans and shaft during the flaccid, tumescence, and rigid phases of penile erection using a biothesiometer (Model PVD; Bio-medical Instruments Co., USA). Artificial penile erection was induced by intracavernosal injection of prostaglandin E1 5-20 micro gram. RESULTS: Penile sensitivity revealed no significant difference among the three groups during the flaccid phase but was significantly lower in the Impo and control groups than in the PE group during the tumescence and rigid phases (p<0.05). Thus, the PE group had penile hyperesthesia in comparison with the other groups during erection. The penile sensitivity values in the three groups showed no significant differences according to location of the penis during the flaccid, tumescence and rigid phases. CONCLUSION: The pathogenesis of premature ejaculation seems to involve peripheral nerve sensitivity rather than being a reaction to the hypoxic state on full erection.

Signet ring cell carcinoma has been previously described in many organs, most frequently in the stomach, and rarely in the colon, rectum, gallbladder, pancreas, breast, nadsal cavity, prostate, urinary bladder and ureter. Signet ring cell carcinomas in the lung, especially, when examined by small biopsies, are generally believed to be metastatic. This case was diagnosed by bronchoscopic biopsy. We also examined various organs by noninvasive method, including UGI series, barium enema and abdomen CT scarf, but all studies were nomal. Patient received cisplatin and etoposide combination chemotherapy followed by local radiotherapy ai a primary non-small cell lung cancer. Patient died of his disease 6 months after diagnosis. Now we report a case of primary signet ring cell carcinoma of the lung.

OBJECTIVE: Inappropriate neural control of the quadriceps femoris muscle group has been implicated in patellofemoral pain syndrome (PFPS) and the methods of biomechanical assessment of PFPS has been developed recently. The aims of the present investigation were to evaluate the effects of therapeutic exercise in the alleviation of PFPS and to develope objective clinical test for PFPS. METHOD: We investigated the onset time of the isometric contraction of vastus medialis oblique muscle (VMO) and the vastus lateralis muscle (VL) under four different conditions: knee flexion and extension in weight bearing (standing) and non-weight bearing (sitting on chair) situations. For each condition, onset times of EMG activities and onset times for VMO and VL were determined from five trials of isometric contraction. In addition, we compared knee flexor and extensor torques in control group and subjects with PFPS. To evaluate the effects of the exercise we compared the onset time difference (onset time of VL-onset time of VM) and quadriceps muscle torque at pre- and post- exercise in PFPS groups. RESULTS: In PFPS group, onset time of VMO during knee extension was significantly longer than the onset time of VL and the knee extensor torque was considerably weaker in comparison with normal group. Although onset time difference was not changed after exercise program, there were significant increase in knee extensor torque in subjects with PFPS. CONCLUSION: The role of exercise in the rehabilitation of quadriceps functions is to reduce the pain, to strengthen the knee extensor, and further accurate diagnostic tools and methods for the result of therapeutic exercise in PFPS are needed.
