A 66 year old man with history of dizziness and occasional headache for a month was found to have right subclavian steal syndrome confirmed by angiogram. Right radial pulse is very weak. Blood pressure on left is 130/70mmHg and on right 70/50. Marked Bruits are audible on right side of neck and shoulder area.

The purpose of this study was to evaluate the prevalence rate of low back pain (LBP) in the high school students and to analyze the differences and correlations with the spinal-pelvic structural variations and disability index with LBP. The subjects are 499 high school students (236 males, 263 females: mean age, 16.38 years). They were assessed for LBP with the numerical rating scale (NRS) and for disability with the Korean version Oswestry disability index (KODI). All subjects were to take the plain radiographic examination for spinal-pelvic structural variations including thoracic, lumbar, thoracolumbar Cobb's angle, lumbar lordotic curve, sacral slope, pelvic tilt and pelvic incidence. All subjects were divided into two groups by NRS scores (0, 1=no/minimum pain group [NMP group], 2-10=low back pain group [LBP group]). The prevalence rate of LBP of all subjects was 56.7% (n=283). NRS and total KODI scores were higher in the LBP group (3.38 cm/11.83%) than NMP group (0.07 cm/2.74%) (p<0.001). In the spinal-pelvic structural variations analysis, the thoracic Cobb's angle was significantly high in LBP group (p<0.05), but others were shown no differences between the both groups (p>0.05). NRS had significantly positive correlation with KODI (p<0.001). NRS and KODI did not demonstrate any correlations with spinal-pelvic structural variations (p>0.05). In conclusion, this study showed high prevalence rate of LBP in the high school students, but did not show significant correlations with the spinal-pelvic structural variations and disability index.

PURPOSE: It has been shown that the sensitization to inhalant allergens on the development of asthma or rhinitis in childhood is related to hereditary disposition and environmental factors. This study was conducted to compare the degree of sensitization to major inhalant allergens in bronchial asthma and rhinitis and to find factors which have an effect on it. METHODS: Skin prick tests were done on the 410 atopic bronchial asthma and rhinitis patients who visited the pediatric allergy clinic from January 1987 through December 1996. We divided the patients into 3 groups: an indoor allergen group sensitive to D.p., D.f., cat fur, dog hair and cockroach; an outdoor allergen group to tree pollen, ragweed pollen, and grass pollen; and a group to both indoor and oudoor allegens. RESULTS: 1) Based on their ages, the prevalence of sensitization was relatively high in 5-6 years old, to indoor allergen and in 11-12 years old to the outdoor allergen. 2) Among the subjects sensitized only to indoor allergens, 34.2% had asthma. 6.7% had rhinitis, and 59.1% both diagnoses. For those sensitized only to outdoor allergens, these values were respectively 29.0%, 48.4% and 22.6%, respectively. 3) The prevalence of indoor allergen sensitization was significantly high in children, living in house, in urban areas, and having carpet/sofa/bed at home(P<0.05). CONCLUSIONS: The younger age group showed more sensitization to indoor allergens than to outdoor allergens. The indoor allergens were strongly related to asthma and the outdoor ones to rhinitis. As a result, it seems that it is very helpful for a prevention of asthma in childhood to take an early environmental control for inhalant allergens.

Benign paroxysmal positional vertigo (BPPV) is a commonly presenting problem at the emergency department. Three types have been recognized based on the pathogenesis of BPPV. The first is posterior-canal canalolithiasis, the second is horizontal-canal canalolithiasis, and the last is horizontal-canal cupulolithiasis. With the first two types of BPPV, an otolith-repositioning manuever can be performed quickly at the bedside with rapid results, often providing much satisfaction to both patient and physician. However, in the case of horizontal-canal cupulolithiasis, no established repositioning maneuver existed until recently. In 2000, Jo et al. developed a new repositioning maneuver and reported excellent results. We report a case of BPPV horizontal-canal cupulolithiasis that immediately responded to the maneuver of Jo et al. and strongly recommend use of this repositioning maneuver at the emergency department.

This experiment was performed to study the morphological responses of the thymic cortex of the mice after administration of BCG. Healthy adult mice weighing 25gm each were divided into normal and experimental groups. BCG[0.03X108-0.32X108 CFU] were injected subcutaneously to the animals every other day, and animals were sacrificed at 4 days, 1 week, 2 weeks and 8 weeks following the first injection. Thymus were removed immediately after sacrifice and transferred to cold phosphate buffered 2.5% glutaraldehyde-1.5% paraformaldehyde solution[pH 7.3], and cut into small pieces. Tissue samples were fixed for 2-3 hours in the same fixative, postfixed with phosphate buffered 1% osmium tetroxide solution[pH 7.3], dehydrated in a graded series of alcohol, and embedded in araldite mixture. Ultrathin sections stained with uranyl acetate and lead citrate were observed with a JEM 100CX-II electron microscope. The observed results were as follow : 1. In the early BCG treated groups, a few eosinophile leucocytes were observed, but more eosinophils were observed in later groups. Some elongated and bar-shaped lysosomes with eletron lucent gap were often obserced in the macrophages. 2. Cortical population of thymocytes in the thymus were reduced, whereas territoris of the epithelial reticular cells were expanded especially in 2 weeks and 8 weeks groups. Some portion of the thymic cortex exhibited large intercellular spaces, and a few nuclear bodies filled with materials of medium density were observed in the epithelial reticular cells. 3. In the 8 weeks groups, macrophages, plasma cells and eosinopile leucocytes and developing eosinophile leucocytes were often observed in the thymic cortex. Distended cisternae of granular endoplasmic reticula and newly forming prosecretory granulses in the Golgi complex were ovserved in som plasma cells. From the above results, it was suggested that repeated treatment with BCG could induce disturb the maturation and differentiation of the T lymphocytes. In turn, BCG, if repeatedly injected, may disturb the immunological medchanism.
