We reviewed 217 patients (270 cases) of thoracic and lumbar fractures and fracture-dislocations, who were treated at Hanyang University Hospital from January, 1977 to December, 1985. We classified spinal injuries according to three column theory and then analyzed the cause of injury, sex-age distribution, treatment and neurological injuries. The results were as follows: 1. The cases were classified into 4 different categories according to the three column theory; compression fractures (191 cases, 70.7%), burst fractures (54 cases, 20.0%), fracture-dislocations(22 cases, 8.2%), and seat belt type injuries (3 cases, 1.1%). And each of these 4 different categories was then subdivided into subtypes. 2. The most common cause of injury was fall from a height (45.2 %). 3. The neurological injuries were occurred in 21 patients (9.7%). The 16 patients with neural deficit in fracture-dislocation, 15 patients were flexion rotation type. The 5 patients with neural deficit in burst fracture, all were incomplete neural deficits. 4. The greatest advantage of Luque instrumentation was an early rehabilitation without external surport.

OBJECTIVES: This study was conducted to develop a Korean version of the Participatory Action Oriented Training (PAOT) program and training materials for improvement of agricultural working environments. METHODS: The PAOT manual and checklist were developed on the basis of the original English version of the training materials, a questionnaire survey of agricultural health and safety professionals, and a brainstorming conference. Good example pictures were collected through visits to agricultural workers' houses, and an easily understandable picture was drawn by an animation specialist. A PAOT action manual and five types of action checklists were developed for use in different agricultural environments. Each action checklist contained six categories and 38 items of agricultural health and safety principles; the six categories were material storage and handling, work stations and tools, machine safety, physical environment, working schedule and organization, and basic health and safety management. Incorporating these training materials, a one-day Korean PAOT program was developed. RESULTS: Among 307 candidate agricultural workers from four rural Korean villages, 94 workers (59 males, 35 females) participated in a PAOT from July 2007 to Oct 2008. The PAOT program was successful and the mean self-estimated satisfaction score of the participants was greater than 90%. CONCLUSIONS: A Korean PAOT program and training materials were successfully developed and applied to Korean agricultural workers. Although more studies are needed, it is expected that PAOT will greatly contribute to the improvement of agricultural working conditions and health and safety through the use of agricultural workers' self initiatives.

The confirmatory diagnosis of Moyamoya disease has been obtained by invasive angiographic examination. We report the results of MRI and transcranial doppler sonography of three cases ol Moyamoya disease, which ws disgnosed by clinical and angiography. We think that the diagnosis of Moyamoya disease can be made by noninvasive MRI and transcranial doppler sonography without conventional invasive angiography.

BACKGROUND & OBJECTIVE: Huntington disease(HD) is clinically diagnosed by the triad of autosomal dominant inheritance, involuntary movements mainly chorea and dementia. The phenotype of HD is variable and other diseases can have same phenocopy. Therefore gene diagnosis of HD becomes essential for confirmatory diagnosis. Recent discovery of an expanded CAG trinucleotide repeat at the telomeric position of chromosome 4p made the gene diagnosis possible even in sporadic cases. We examined the length of CAG repeat in Huntington gene locus by PCR method in clinically diagnosed HB patients to make a confirmatory diagnosis. METHODS: Three patients with chorea, dementia and family history were tested. All laboratory tests including MRI had been normal so far. Genomic DNA was extracted from their WBC, and PCR was done on Huntington gene locus using primers modified from HD Collaboratory Group. Agarose gel electrophoresis to examine the rough degree of expansion, polyacrylamide gel electrophoresis to determine repeat length, and sequencing of the expanded allele were done. As a second step, three choreic patients without family history, one patient with tardive dyskinesia and one whole HD family were tested. RESULTS: Three choreic patients with family history showed expansion of CAG repeats in the amplified site. Two sporadic choreic patients, and one asymptomatic member in a HD family had increased CAG repeats. CONCLUSION: We confirmed expansion of CAG repeats in Huntington gene locus in clinically diagnosed HD. None of the patients had caudate atrophy, which has been considered an early finding. Sporadic choreic patients could be diagnosed as HD by gene study. Presymptomatic case was found in a family screening, and will need to be followed. Gene analysis offers a critical tool to make a confirmatory diagnosis of HD, and will be a powerful tool in genetic counseling.

The seasonal occurrence and habitat of two parasitic copepods, Peniculus minuticaudae (Shiino, 1956) and Peniculus truncatus (Shiino, 1956) (Siphonostomatoida, Pennellidae) infecting the fins of black scraper Thamnaconus modestus and Korean rockfish Sebastes schlegelii, respectively were investigated. The fishes were collected from Tongyeong marine living resources research and conservation center, southern coast of Korea as five per month for two years from July 2011 to June 2013. In total, 391 copepods of P. minuticaudae were collected in two years, in contrast to P. truncatus. Prevalence was 85%, mean intensity was 3.25, and maximum intensity was 33. Season wise, the infestation was observed as the highest in autumn (September-November) season, and the lowest in winter (December- February). It was infested only on fins of black scrapers. Abundance of P. minuticaudae was found on the pectoral fin (43.5%), followed by anal (22.5%), second dorsal (20.5%) and caudal fins (13.5%). Statistically significant interactions were observed between season, infestation and infected regions (P<0.001). It is also reported for the first time in Korea from the fins of wild threadsail filefish Stephanolepis cirrhifer from Busan, Jeju, Tongyeong and Yeosu fish markets. It can be a new record on its host and localities. A total of 51 P. truncatus were collected with the prevalence of 37.5%, mean intensity of 0.37 and maximum intensity of 6. Season wise, infestation was observed as the highest in summer (June-August), and the lowest in winter. Attachment site was the dorsal fin and not found from any other fins of rockfish. Statistically significant interaction was observed between season and infestation (P<0.05). This is the first report on the ecology of these two pennellids.

OBJECTIVES: To compare results of 4 different extraction methods in laparoscopic management of dermoid cyst. STUDY DESIGN: This article is a retrospective, multicenter study for 247 patients with benign dermoid cyst in period of 1995-1998. Dermoid cyst was extracted by Endopouch (99 cases), puncture-irrigation-extraction (69 cases), colpotomy (35 cases), and dermoid cyst as a "pouch bag" (44 cases). RESULTS: We analyzed irrigation amount, operative time, postoperative hospital stay and complications by four different extraction methods. Endopouch extraction method needed less amount of irrigation fluid for cleaning the abdominal cavity and had a shorter postoperative hospital stay (ANOVA, p=0.0001). There were no significant differences in operative times among groups. There were four cases of morbidity in puncture-irrigation-extraction method (6%), three had fever (> 38degrees C) and one intraabdominal abscess. One incisional hernia was noted in "pouch bag" method (2%). CONCLUSIONS: We recommend minimal spillage method for extraction of dermoid and careful irrigation of abdominal cavity to prevent potential risk of chemical peritonitis such as Endopouch, "pouch bag", and colpotomy with the exception of puncture-irrigation-extraction method.

INTRODUCTIONAneuploidy screening is widely practised in the field of obstetrics in current times. This study thus aims to gain an insight on pregnant women's knowledge and risk perception of Down syndrome and first trimester screening (FTS), as well as their views on various potential pregnancy outcomes and how these may affect their decision-making processes.

MATERIALS AND METHODSA cross-sectional questionnaire-based qualitative study of consecutive 50 women choosing to undergo FTS at KK Women's and Children's Hospital (KKH), Singapore was conducted. The women completed a questionnaire after their FTS pretest counselling session. Basic knowledge of Down syndrome and FTS as well as participants' risk perception with regards to various cut-off values used in FTS were examined. Patients' views of various potential pregnancy outcomes were also studied.

RESULTSMost patients had good retention and comprehension of what FTS entailed after a FTS counselling session at the KKH Antenatal Monitoring Clinic. However, knowledge of the risks of invasive diagnostic testing was poor. Patients also did not possess an adequate understanding of FTS risk values. With regards to risk perception, patients had very different views on acceptable pregnancy outcomes and what constituted a high-risk FTS value to them personally. A significant number of women were concerned even at medically low-risk values of 1:500 and 1:1000 in FTS. The majority of patients viewed highest detection rate followed by a lowest false positive rate as the more important factors impacting their choice of a Down syndrome screening test.

CONCLUSIONThis study demonstrates the diversity of pregnant women's risk perception, risk aversion and participation in decision processes when there are 2 different values in competition. The study also highlights our patients' gaps in knowledge and lack of understanding of risk values used in FTS.

Growth Patterns of cranium measured directly as head circumference have been well documented. With the recent progress in CT, it is easy to measure the size and cross sectional area of the structure. The author chose themidvnetricular level of brain CT scan and measured the product of maximum anteroposterior and lateral dimension and cross sectional area. The age of infants ans children was 0 to 2 years old. The author obtained the following results through statistical analysis; 1. The maximum anteroposterior dimension and the cross sectional area were obtained through the computerized program of CT scanner. Using these measurements, monthly growth curve was obtained and which shows accelarated growth in the initial 12 months especially during the first four months, and followd by reduced rate of growth in the next 12 months. 2. Comparing the size of the calvarium between sexed,females' were somewhat larger than males', but there was no statistical significance. 3. Comparing the crosssectional area with the head circumference, high correlation was seen(correlation coefficient=0.96). Similarelationship was also seen between the product of cranial linear dimensions and the head circumference(correlationcoefficient=0.93). Also statistically significant relationship was noted between the cross sectional area and theproduct of the cranial linear dimensions(correlation coefficient=0.97). 4. Using the cross sectional area and theproduct of cranial linear dimenstions, monthly average value and the 95% significant range were obtained which canbe used as indices for the growth and development of cranium. Of these, the product of cranial linear dimensionscan eadily be measured by brain CT images, which may be useful on practical basis.
