The systolic time intervals and hemodynamics were measured in 10 cases of acute anemia and 28 cases of chronic anemia. The measurment was done by non invasive technique, i.e., simultaneous recording of ECG, PCG and carotid and femoral pulse tracing with paper speed 100mm/sec. Compared with healthy persons chronic anemia showed significant reduction of the systolic time intervals except QS1, but the systolic time intervals were unaltered when they were corrected by pulse rate, diastolic pressure and stroke volume. Acute anemia showed decreased of the systolic time intervals except QS1 also the decrease of isovolumic contraction time(ICT) and QS2 when corrected as above. The preejection period(PEP)/left ventricular ejection time(LVET) ratio were not altered. ICT, PEP and PEP/LVET ratio decreased in proportion to the levels of hemoglobin. The heart rate, stroke volume and cardiac output showed significant increase in chronic anemia but mild incease in acute one. The decrease of diastolic pressures and peripheral resistances were more pronounced in chronic anemia than in acute one.

BACKGROUND: Few studies have demonstrated an enhanced skin responsiveness to opiates in atopic subjects. OBJECTIVE: To determine whether the skin response to morphine is increased in atopics and to assess the clinical usefulness of morphine skin prick test in diagnosis of allergic diseases. METHOD: Allergy skin prick tests were performed using 55 common allergens, histamine, and morphine in 158 patients with allergic diseases. RESULTS: Wheal and flare sizes for morphine (1mg/mL) were significantly related to and smaller than those for histamine (1mg/mL). Although the proportion of subjects with allergic rhinitis and the level of serum total IgE were not different between responders (wheal >- 2mm) and nonresponders to morphine, the positive response rate to allergens was significantly lower in nonresponders. The flare sizes for morphine were significantly higher in positive allergen test group (A/H ratio >- 0.5). Among positive allergen test group, the subjects with atopy score >- 5 showed a larger flare size for morphine than those with atopy score < 5 while the sizes for histamine were not different. CONCLUSION: Morphine skin prick test is helpful for detecting false negative responses to allergens, and morphine skin test responses are increased in highly atopic patients probably due to enhanced mast cell releasability.

We have experienced a case of neurofibromatosis with unusual giant pigmentation, which presents itself as a 28 cm x 40 cm sized, serrated bordered light brownish patch speckled with small dark hyperpigmented macules on his back. Histopathologic examinations of light brown patch and speckles showed only an increase in basal melanin pigmentation.

Leg length discrepancy or short stature is a significant problem to patient psychosocially, cosmetically, and there has been many efforts for limb lengthening. There are many report about lower limb lengthening since the first description of femoral lengthening by Codivilla in 1905. Although limb lengthening using external fixator was popularized by Anderson, the result was poor because of many difficulties in techniques and complications. Recently, a great progress in lower limb lengthening was made by distraction osteogenesis by llizarov and callotasis by De Bastiani. But as such exter- nal fixator has some problem in technique, cosmesis or complications. Therefore gradual elongation intrameduilary nailing(Albizzia) developed by Guichet in 1986 has gained attention for more stability and relatively less discomfort. We reviewed 18 cases in 11 patients(5 males and 6 females) who visited the department of Orthopedic Surgery of Severance Hospital at Yonsei University with limb leg length discrepancy due to sequeale of poliomyelitis, familial short stature and Turner syndrome. They all underwent lower limb lengthening using Albizzia technique between December 1995 and January l997. The average age at the time of the operation was 22.7 year. Famiiial short stature was in 12 cases(67%), Turner syndrome in 2 cases(11%), and leg length discrepancy due to the sequelae of poliomyelitis in 4 cases(22%). The site of lengthening were 5 cases of femur(28%) and l3 cases of tibia(72%). The latency period was average of 7 days. During the distraction period, 15 ratchetings per day(1 mm/day) were performed. In case of bilaterai femoral lengthenings, average length of gain(LG) was 6.0cm and percentage of increase(PI) l6.8%(16.2-17.4), lengthening index(LI) 1.2 month/cm(0.75-2.2). In case of unilateral femoral lengthening, LG was 3.8cm, Pl 7.8 %, Ll 1.3 month/ cm. In case of bilateral tibial lengthening, average LG was 5.5cm(3.5-6.0~) and Pl 18.8%(12.0-22.9), LI 1.3month/cm(0.67-2.3). In case of unilateral tibial lengthening, LG was 2.9cm(2.3-3.5), P1 9.4 %(7.7-11.7), LI 2.8 month/cm(2.2-3.1). Lengthening index in poliomyelitis by llizarov was 3.l month/cm, but it was 1.3 in femur and 2.8 in tibia hy Albizzia method. There are some advantages and disadvantages or contraindications and indications of the Albizzia technique. We suggest that the Albizzia technique is more stahle, more comfortable and no longer lengthening time compared to external fixator such as Ilizarov.
