This paper describes the incidence of transport accident for the period, 1955-1965. Transport accidents were classified into three categories, viz. railway(WHO Classification of Diseases, E-802), watercraft(E850-E858) and motor vehicle accidents(E810-E835, E840-E841, E844-E845). Crude data on the subject were collected from the various sources of Government Statistical Books including Statistical Year Books edited by the Central Office of Economic Planning Board, Annual Police Reports by the Ministry of Home Affairs, and the national and local associations for road traffic safety. From the data incidence and mortality rates by year, month and local province were computed and other variables relevant to the epidemiology of accidents were observed. The following summary could be drawn: 1. Death rates due to transport accidents per 100,000 population were 12.3 for 1955 and 9.7 and 1965. The incidence of injury due to the same cause were 34.0 for 1955 and 35.9 for 1965. 2. Death rates by transportation vehicle showed 9.0 due to motor vehicle accidents, 1.7 due to water-crafts, and 1.6 due to railway trains for 1955. In 1965 death rates were 6.0 due to motor vehicles, 1.2 to water-crafts and 2.4 to railway. 3. Seasonal distribution of transport accidents revealed that car accidents occur more frequently in spring and fall seasons while ship accidents do in winter and train accidents more in summer. 4. Both car and ship accidents slightly decreased during the past decade, 1955-1965, whereas the accidents of railway trains showed a tendency of increase. 5. Although the survey on railway accidents excluded the injuries of passengers or railway employees corresponding to WHO classification of diseases, E801, due to inaccuracy of data, it is roughly estimated that the same number of causalities as the incidence among pedestrians or any other than passengers or employees assumed to be at work(E 802).

The neurovascular cross-compression (NVCC) of the eighth cranial nerve (CN) is a clinical entity with symptoms of recurrent vertigo or tinnitus. Although the diagnostic criteria have been defined, the precise clinical presentation and pathomechanism have not been clarified. The treatment response to the carbamazepine; drug of choice for first line medical treatment, has been considered as one of the diagnostic criteria. Herein, we present a case of chronic uncompensated unilateral vestibular hypofunction who responded dramatically to carbamazepine medication. A 55 year-old male admitted to the hospital with symptoms of recurrent oscillopsia and headache for more than 7 years. His symptoms were aggravated by positional changes. Vestibular function tests showed spontaneous nystagmus, canal paresis on caloric test and vestibular dysfunction on dynamic posturography, which represented unilateral uncompensated vestibular hypofunction. Although his symptom was not relived by vestibular rehabilitation, he was treated with carbamazepine. A long standing uncompensated unilateral vestibular hypofunction without any auditory symptoms could be one of the clinical presentations in NVCC of the eighth CN.

PURPOSE: To investigate levels of serum homocysteine in patients with pseudoexfoliation syndrome and the association between serum homocysteine levels and risk of coronary heart disease. METHODS: From March 2013 to September 2013, 37 patients with pseudoexfoliation syndrome and 59 age-matched patients (control group) were enrolled in this prospective study. Serum homocysteine levels were compared between the 2 groups. We compared the estimated 10-year risk of coronary heart disease based on Framingham risk score between the 2 groups. Additionally, we analyzed correlations between risk of coronary heart disease and serum homocysteine levels. RESULTS: The mean homocysteine level of patients with pseudoexfoliation syndrome was significantly higher than the control group (13.3 ± 6.8 µmol/L vs. 10.0 ± 5.2 µmol/L, p = 0.009). The rate of high risk defined as a 10-year coronary heart disease risk >20% in the patients with pseudoexfoliation syndrome was significantly higher than in the control group (21.4% vs. 4.4%, p = 0.048). Correlation between serum homocysteine levels and estimated 10-year risk of coronary heart disease was statistically significant (r = 0.578, p < 0.001). CONCLUSIONS: Hyperhomocysteinemia and high risk of coronary heart disease were observed in patients with pseudoexfoliation syndrome. Therefore, we suggest efforts to prevent coronary heart disease in pseudoexfoliation syndrome patients with hyperhomocysteinemia are necessary.

PURPOSE: In order to improve dose homogeneity and to reduce acute toxicity in tangential whole breast radiotherapy, we evaluated two treatment techniques using multiple static fields or universal compensators. MATERIALS AND METHODS: 1) Multistatic field technique : Using a three dimensional radiation treatment planning system, Adac Pinnacle 4.0, we accomplished a conventional wedged tangential plan. Examining the isodose distributions, a third field which blocked overdose regions was designed and an opposing field was created by using an automatic function of RTPS. Weighting of the beams was tuned until an ideal dose distribution was obtained. Another pair of beams were added when the dose homogeneity was not satisfactory. 2) Universal compensator technique : The breast shapes and sizes were obtained from the CT images of 20 patients who received whole breast radiation therapy at our institution. The data obtained were averaged and a pair of universal physical compensators were designed for the averaged data. DII (Dose Inhomogeneity Index : percentage volume of PTV outside 95-105% of the prescribed dose), Dmax (the maximum point dose in the PTV) and isodose distributions for each technique were compared. RESULTS: The multistatic field technique was found to be superior to the conventional technique, reducing the mean value of DII by 14.6% ( p value<0.000) and the Dmax by 4.7% ( p value<0.000). The universal compensator was not significantly superior to the conventional technique since it decreased Dmax by 0.3% ( p value=0.867) and reduced DII by 3.7% ( p value=0.260). However, it decreased the value of DII by maximum 18% when patients' breast shapes fitted in with the compensator geometry. CONCLUSION: The multistatic field technique is effective for improving dose homogeneity for whole breast radiation therapy and is applicable to all patients, whereas the use of universal compensators is effective only in patients whose breast shapes fit inwith the universal compensator geometry, and thus has limited applicability.

OBJECTIVE: Neuroleptic Induced Akathisia(NIA) often occurs in neuroleptic treated patients. Cyproheptadine, an antiserotonergic agent, was used to treat neuroleptic induced akathisia. METHOD: In an open trial 21 neuroleptic-treated patients with akathisia were administrated Cyproheptadine(16mg/day) over 4 days. Assessment of akathisia was evaluated using Barnes' rating scale(BAS) for neuroleptic induced akathisia. The degree of depression and psychosis were assessed by brief psychiatric rating scale(BFRS) and Hamilton rating scale for depression(HAM-D). RESULT: Most patients(20 of 21) with neuroleptic induced akathisia(NIA) showed improvement under the treatment of cyproheptadine. There was no aggravation of psychosis or depression during the treatment. Symptoms of akathisia aggravated when cyproheptadine was discontinued. CONCLUSION: Cyproheptadine may be useful in the treatment of neuroleptic induced akathisia(NIA).

BACKGROUND: Tissue biopsy is of significant importance to the parasitic diseases. This report describes in order to know the species and frequency of human parasitic infection diagnosed by biopsy at the department of anatomical pathology, KyungHee Medical Center. Finally, we estimated the trend of parasitic diseases of tissue in a feature, in Korea. METHOD: 262(0.57%) cases of parasitic infection were reviewed for analysis of the different types of parasitic infection, 45,651 biopsied materials were submitted for routine histopathological examination during a period of 12 years from 1972 to 1983 at the department of anatomical pathology, KyungHee Medical Center. RESULTS: They consisted of 136 cases of cysticercosis, 73 clonorchiasis, 16 amebiasis, 12 paragonimiasis, 9 ascariasis, 9 sparganosis, 4 scabies, 1 taeniasis, 1 enterobiasis and 1 anisakiasis. 136 cases of cysticercosis were mainly of the skeletal muscle and subcutaneous tissue. The 73 cases of clonorchiasis occurred mainly in the liver and gallbladder. In the 16 cases of amebiasis, the liver and the rectum were the main loci. In 12 cases of paragonimiasis, pleura was the main site. CONCLUSION: The frequency of parasitic infections found in biopsied specimens was found to decrease as the years passed by, but some disease such as sparganosis showed a possible increase. Tissue biopsy is an important method for detection of tissue or ectopic parasitic infections.

Superior vents lava(SVC) syndrome is mostly related to a malignant process, but many different benign causes haute also been described. We report a case of SVC syndrome caused by Klebsiella pneumonia diagnosed by sputum culture and serial chest X-ray changes. A 27-year-old man had been in stable health until three days before admission, when he complained of pleuritic chest pain, facial flushing, and shortness of breath. Examination of the head and neck disclosed edema of face and both arms, and jugular venous distention to the angle of the jaw. The chest auscultation resealed decreased breath sound without crackle on right upper lung field. The chest roentgenogram showed homogenous air space consolidation on right upper lobe, asociated with downward displacement of minor fissure and contralateral displacement of trachea, but air bronchogram was not seen. We began antibiotic therapy under impression of pneumonia after assailable culture was taken from blood and sputum. SVC scintigraphy showed stasis of drain of right brachiocephalic vein at the proximal portion with reflux into the right internal jugular vein and faintly visible SVC via the collaterals. Sputum culture resealed Klebsiella pneumoniae. Antibiotic therapy resulted in a cure of infection and disappearance of facial swelling. Follow-up SVC scintigraphy after 20 days showed normal finding. We first report a case of SVC syndrome caused by klebsiella pneumonia

Background: and Purpose The relationship between napping and cognition remains controversial. This study aimed to investigate the association between napping and cognition according to sleep debt in the Korean adult population. Methods: A population-based nationwide cross-sectional survey was conducted in 2018. A two-stage stratified random sample of Koreans aged ≥19 years was selected and evaluated using questionnaires by trained interviewers. Cognitive function was assessed using the Mail-In Cognitive Function Screening Instrument (MCFSI). Sleep habits on weekdays and weekends, napping, and subjective sleep requirements were assessed using the questionnaires. Accumulated sleep debt was calculated by subtracting the weekly average sleep duration from subjective sleep requirements. Sleep quality, daytime sleepiness, insomnia, depression, demographics, and comorbidities were assessed. Participants were grouped into those with sleep debt ≤60 min and those with sleep debt >60 min. Multiple linear regression was used to estimate the independent association between the factors and cognition. Results: In total, 2,501 participants were included in the analysis. Naps were reported in 726 (29.0%) participants (nappers). The mean MCFSI score was higher in nappers (3.4±3.6) than in non-nappers (2.3±3.0) (p<0.001). Multiple linear regression controlling for age, alcohol, smoking, depression, insomnia, daytime sleepiness, sleep quality, and education revealed that 30 to 60 min of napping was associated with worse cognitive function in participants with sleep debts ≤60 min, while >60 min of napping was associated with better cognitive function in participants with sleep debts >60 min. Conclusions In general, naps are associated with worse cognitive function in the Korean adult population. However, for those with sleep debt of >60 min, naps for >60 min were associated with better cognitive function.f

Transfemoral access (TFA) is a widely used first-line approach for most peripheral vascular interventions. Since its introduction in cardiologic and neurointerventional procedures, several advantages of transradial access (TRA) over TFA have been demonstrated, such as patient preference, lower complication rates, early ambulation, and shorter hospital stay. However, studies reporting the safety and efficacy of this approach for peripheral vascular interventions performed by interventional radiologists are relatively few. This review aimed to summarize the technique and clinical applications of TRA in percutaneous transcatheter visceral artery embolization and the management of complications.
