BACKGROUND: Headache is a common complaint in patients presenting to the emergency department(ED). Many patients suffered sustained headache even after presenting to the ED. This study investigate whether the patients were received analgesics and timely adequate. METHOD: We analyzed 131 adolescent and adult patients with non-traumatic headache without any neurologic deficit in two emergency department during 6 months period retrospectively. RESULTS: The positive and negative predictive value according to primary impression were 47% and 74% respectively. The mean time to take brain computed tomography(CT) after ED presentation was 120 minutes. The patients with primary impression of intracranial hemorrhage(mainly SAH) were the most fast(mean time 88+/- 70 minutes). 28(21%) patients were received analgesics before taking brain CT(after ED presentation), and 70(53%) patients after CT, 27(54%) patients after cerebrospinal fluid examination. The mean time interval were 43, 126 and 149 minutes on each group being received the analgesics. CONCLUSION: According to this study many patients suffered sustained headache before being classified to certain type of disorder. It may due to the reasons that there were no definite guidelines treating headache, the pain itself, or the physician treats patients as physician's way.

As a new concept of resistive exercise, isokinetic exercise was developed during the early 1950's. In isokinetic exercise, the subject works at a fixed speed against variable and totally accommodating resistance. The isokinetic equipment has been used widely as a therapeutic modality in clinical setting, as a training and testing device for sports practicians, and as a method for scientific examination of postoperative status of muscles and joint function for orthopedists. In order to acquire the isokinetic normative data of the knee for clinical use, we examined the flexor and extensor muscle force of the knee joint in 160 subjects with Cybex II. The results were as follows; 1. Mean values of extensor strength were 76.04 ft.-1bs in right knee 75.45 ft.-lbs in left knee, 78.42 ft.-1bs in dominent hand side leg 73.84 ft.-1bs in non-dominent hand side leg, and 82.52 ft.-1bs in dominent leg 71.93 ft.-lbs in non-dominent leg. 2. Sex difference of extensor strength were 95.13 ft.-lbs in male 55.98 ft.-1bs in female, and that of flexor strength were 54.90 ft.-1bs in male 33.68 ft.-1bs in female. 3. Mean of position angle of maximal torque were between 58° and 65° for extensors, 35° and 45° for flexors. 4. Mean of total range of motion at working isokinetically with 60°/sec speed was 99°. 5. Mean values of extensor power were 54.43 ft.-1bs in male 30.63 ft.-lbs in female, and that of flexor power were 35.99 ft.-1bs in male 22.42 ft.-1bs in female. 6. Strength and power decreased as ages getting old, and there was significant diminish between 4th decade and 5th decade. 7. Power endurance had more difference when it was compared with occupation. Mean value of power endurance was between 12 times and 18 times.

PURPOSE: The aim of this study was to evaluate the utility of contrast-enhanced MRI with first-pass and delayed images in prediction of myocardial viability after acute myocardial infarction. MATERIALS AND METHODS: Ten patients (M:F=:4, mean age =6 5 years) with acute myocardial infarction underwent first-pass image after bolus injection of gadolinium (one image/sec for 120sec)and delayed image (7 2 minutes later). According to 60 segments on midventricular level, the assessment of MRI were concerned about location of lesion, depth of lesion, enhancement on first-pass image and enhancement pattern on delayed image. MRI findings were compared with wall motion on resting echocardiography and stress or follow-up echocardiography. RESULTS: 1) MRI findings were classified into 4 types: normal enhancement on first-pass and delayed images (type 1), normal enhancement on first-pass image and nontransmural hyperenhancement on delayed image (type 2), non-transmural enhancing defect on first-pass image and transmural enhancement with endocardial non-enhancing defect on delayed image (type 3), and transmural enhancing defect on first-pass image and transmural hyperenhancement on delayed image (type 4).2) Type 2 suggested viable myocardium and type 3 had high porbability of viability. Type was compatible with non-viable myocardium. CONCLUSION: Enhancing defect on first-pass image and involving thickness on both the first-pass image and delayed image in contrast enhanced MRI may predict myocardial viability.

Solitary rectal ulcer syndrome(SRUS) is a rare disorder in children. The incidence of SRUS is highest in young adults, and sex distribution is equal, or there may be a slight female predominance. There are few investigations about the exact incidences and effective treatment protocols of SRUS in children. The clinical symptoms and signs of SRUS are accompanied by rectal bleeding, mucous discharge, prolonged straining, tenesmus, and localized perineal pain. The time intervals between the onset of symptoms and the establishment of accurate diagnosis varied between five and seven years. It was the reason why most patients showed nonspecific symptoms and laboratory test results. We have described a 12-year-old female patient, who suffered intractable lower abdominal pain for three years, and was diagnosed as a solitary rectal ulcer syndrome by rectosigmoidoscopy.

PURPOSE: The purpose of this study was to investigate the pattern of cerebral response to motor tasks in patients with schizophrenia compared with normal subjects using functional MRI. MATERIALS AND METHODS: Nine right handed-schizophrenic patients and six right-handed normal subjects were included. We used right hand movement as task. Series of 120 consecutive echo-planar images per section were acquired during three cycles of task and rest activations. Lateralization index of cortical response was measured and compared between patients and normal subjects. RESULTS: Right hand motor task was associated with greater activation in left sensorimotor cortex than the right in normal subjects. Schizophrenia patients showed relatively decreased activation in left cortex and increased activation in right cortex compared with normal subjects. In one patient, reversed lateralization was noted. CONCLUSION: Normal hemispheric asymmetry of cortical response to motor task was found in different pattern in schizophrenia. Our result is consistent with functional disturbance of motor circuitry in this disorder. Functional MRI will play an important role in diagnosis and research of this disorder.

PURPOSE: Many studies have reported associations of early postnatal growth failure in preterm infants with several morbidities. However, the risk factors for postnatal weight loss (PWL) in late preterm infants have not been identified. We investigated the independentrisk factors for PWL in late preterm infants.METHODS: This was a retrospective cohort study. We enrolled 369 late preterm infants born at 34⁺⁰ to 36⁺⁶ weeks gestational age who were admitted to the Soonchunhyang University Cheonan Hospital between 2015 and 2017. PWL% was calculated as (birth weight–lowest weight)/birth weight×100. The infants were classified into lower (< 5%) and higher (≥10%) PWL% groups by propensity score matching for gestational age, sex, and birth weight. Perinatal risk factors were analyzed using multivariable logistic regression.RESULTS: The lower and higher PWL% groups included 62 and 31 infants, respectively. Antenatal steroids administered within 1 week before birth (odds ratio [OR], 3.26; 95% confidence interval [CI], 1.015 to 10.465; P=0.047), lower total calorie intake during days 1 to 7 (OR, 0.98; 95% CI, 0.977 to 0.999; P=0.027), and phototherapy (OR, 5.28; 95% CI, 1.327 to 21.024; P=0.018) were independent risk factors for the higher PWL%.CONCLUSION: Further studies are needed to identify the risk factors that cause high PWL% according to gestational age and short- and long-term morbidities based on the degree of PWL.

The industrial use of MMMF(man-made mineral fibers), has been increasing, particularly since the banning of most asbestos products. Fibrous minerals can cause health abnormalities currently associated with occupational exposure to glass fiber. This study was conducted to evaluate health risks of glass fiber manufactory workers within the country. we examined questionaries, physical examination including auscultation, chest x-ray, pulmonary function test for 488 male workers, to go through their dermal itching symptoms and respiratory evaluation. we had the results as follows. 1. In 45% of the workers itching had been expressed at their entrance. At that time we was investigating, 18.5% had itching, and most of them complained it when they fall asleep and night. The frequent itching site is waist and groin, upper and lower extremity in order, and it had been expressed mainly during summer and winter. 2. As the results of ventilatory functions test, 6.0% were obstructive type, 1.0% were restrictive type. so, glass fiber exposures should be controlled or elimination by protective devices in the workplace. 3. The means of FVC, FFV1, FFV1% were in normal range. As the comparison of ventilatory functions by age groups, MMF was decreased significantly for the group, 50 years old and more than other groups. And the comparison by the serving periods at glass fiber producing factory, MMF was decreased for the workers had worked for 11-15 years. Therefore, MMF be more sensitive index in the evaluation of ventilatory impairments caused by glass fiber workers.

PURPOSE: To review MR findings of the posterior fossa hemangioblastomas and to evaluate diagnostic value of MRI correlated with CT and anglographic findings. MATERIALS AND METHODS: The MR findings in twelve patients with surgically proven posterior fossa hemangioblastomas including one case of von Hippel- Lindau disease were retrospectively analyzed and correlated with CT (7 patients) and anglographic findings (9 patients). RESULTS: On MRI, five hemangioblastomas were located in the cerebellar hemisphere and seven in the vermis. The masses appeared to be solid in 3 cases(25%), solid tumors with central cyst in 2 cases(17%), and cyst with mural nodules in 7 cases(58%). Abnormal tumor vessels represented by characteristic signal voids on MRI were observed in 9 cases(75%) and were not seen in 3 cases(25%) with mural nodule below 1.5cm in diameter. On pre-contrast CT, hemangioblastomas appeared poorly marginated slightly hyperdense masses in solid tumors, and hypodense cystic masses in cysts. After contrast enhancement, solid tumors were markedly enhanced, but it was difficult to differentiate hemangioblastomas from other tumors. In nine patients, anglograms demonstrated hypervascular blush corresponding to the solid component of the tumors. CONCLUSION: MRI was superior to CT in evaluating the characteristic of abnormal tumor vessels and mural nodules, delineation of tumor margin and tumor extent. Angiography was useful in the diagnosis of cystic hemangioblastomas which contain small mural nodule (less than 1.5cm in diameter) without definite vascular signal voids on MRI. MRI demonstrated solid or cystic tumor with small mural nodule and abnormal vascular signal voids in the posterior fossa should suggest hemangioblastoma.

We experienced a case of Takayasus arteritis with eclampsia in a 43-year-old woman. The patient had angiographically definite Takayasus arteritis with the involvement of right common and internal carotid arteries. On MR images performed at clinical manifestations of eclampsia, unilateral involvement of T2 high signal intensities were demonstrated in right cerebral hemisphere. We report this case with a literature review.
