The purpose of this study was to examine the comparison of growth development, bone mineral density and nutrient intakes between double income families' preschool children(DIFPC) and full-time housewives' preschool children(FHPC). Subjects were 111 preschool children. Anthropometric characteristics and bone mineral density in right forearm were measured. The questionnaire was composed of health status, life style, dietary behaviors, and dietary intakes and was completed by the children's mothers. The average age of the DIFPC(n=60) was 53.02 months and that of the FHPC(n=51) was 54.80 months. The birth height and weight of the subjects were 50.47cm and 3.27Kg for DIFPC and 50.85cm and 3.36Kg for FHPC, respectively. The average height, weight, % body fat, and obesity index were 108.50cm, 18.35Kg, 15.35%, 96.71% in DIFPC and 111.46cm, 19.64Kg, 16.80%, 97.31% in FHPC, respectively. The bone mineral density in forearm of two groups were 0.24g/cm2 in all. The infant feeding method was significantly different between DIFPC and FHPC; 58.9% of DIFPC was fed formula, while 44.4% of FHPC was fed breast milk(p<0.05). Proportions of children for their regular meal were 59.4%, 89.6%, and 61.0% for breakfast, lunch, and dinner, respectively. The major reasons for irregular meal were lack of time and poor appetite for breakfast and snacks for lunch and dinner. Most of the children answered they have snack over once a day, and 60.0% have unbalanced diet. The intakes of energy, calcium, iron, zinc, vitamin A, vitamin B1, niacin, and vitamin C did not meet the Korean RDAs. The intakes of K and vitamin A for DIFPC were significantly higher than those of FHPC(p<0.05, p<0.05). In conclusion, double income families' preschool children more have a low frequency of breast feeding and low intakes of micro nutrients, such as K and vitamin A than full-time housewives' ones.

BACKGROUND: Phantom limb sensation is an unusual position sense of the extremity during nerve block that the position of extremity is misinterpreted as being flexed, or elevated, when actually they are in neutral position. Whether it is from the fixation of proprioceptive input at the time of motor blockade or from unmasking of the pattern which has been already present in the CNS is still controversial. We perfomed this study under the assumption that phantom limb sensation can still be reproduced without the influence of position at the time of nerve blockade. METHODS: Thirty-six patients scheduled for elective orthopedic surgery were randomly assigned. For 26 patients, spinal anesthesia was performed with hyperbaric 0.5% tetracaine or bupivacaine at lateral decubitus position and the position was changed to supine immediately. Existence of phantom limb sensation and the level of anesthesia was recorded at 10 and 20 minutes after injection of local anesthetics. For 10 patients, same local anesthetics were injected after patient's legs were straightened in lateral decubitus position. RESULTS: Forteen out of 26 patients whose position were changed to supine immediately after the injection of local anesthetics experienced phantom limb sensations. Five out of 10 patients whose legs were kept straight before the injection of local anesthetics experienced phantom limb sensations. Previous history of trauma was positively related to the expression of phantom limb sensation. CONCLUSION: Our data showed that the expression of phantom limb sensation is reproducible. And this was not related to the position at the time of spinal anesthesia. Trauma seems to be an important factor related to the expression of phantom limb sensation.

A murime monoclonal antibody (mAb) specific for the envelope glycoprotein gp120 of human immunodeficiency virus type-I (HIV-1) was chemically coupled to pokeweed antiviral protein (PAP) from Phytolacca americana. The immunotoxin was purified by FPLC using 5200 colum. The purified immunotoxin efficiently bound to HIV-infected T cells as evidenced by fluorescence-activated cell sorter analysis. The immunotoxin selectively killed human T lymphoid lines infected with HIV-lIIIB at less than 250 pM of the immunotoxin cells, while PAP or mAb alone did not have any significant effect on infected cells. The uninfected control T cell lines were not affected. Human cells infected with HIV-2 or other HIV-1 strains were not killed, suggesting that the killing depends completely on the antibody used for coupling. These in vitro results suggest that the PAP-mAb conjugate may be used to selectively remove cells expressing viral antigens from individuals infected with HIV.

BACKGROUND: Delays in breast cancer diagnosis may occur in young women due to a low index of suspicion. The purpose of this study was to compare mammography and breast sonography in detection of breast cancer and to suggest a reasonable guideline for breast cancer screening examination. MATERIALS AND MATHODS: Among 820 patients, 102 patients were under 35 years and 122 patients were above 60 years of age. We reviewed medical records, mammograms and/or ultrasonography of 49 patients under 35 years and 48 patients above 60 years of age with pathologically-proven breast cancer. Pathological reports were as follows: Invasive ductal carcinoma(IDC) was present 61.2% of patients in the young age group and ductal carcinoma in situ(DCIS) in 16.3%. IDC was present in 66.6% of the patients in the old age group, and DCIS in 8.33%. We analyzed mammography and ultrasonography to evaluate their usefullness in detecting breast cancer in patients under 35 years and over 60 years of age. RESULTS: The mammographic results are as follows: 1) detection rate of lesion: 83.8%(under 35yrs), 100%(over 60yrs) 2) sensitivity of cancer: 67.6%(under 35yrs), 91.2%(over 60yrs) The ultrasonographic results are as follows: 1) detection rate of lesion: 100% 2) sensitivity of cancer: 87.2%(under 35yrs), 96.7%(over 60yrs) The breas cancer detection rate in women under 35 years old was comparable to that of women above 60 years old in our study. CONCLUSION: A striking histologic finding in the two groups was a higher incidence of nuclear Grade II and III tumors. This finding correlates with the reported increased incidence of high grade tumors inyoung women and may correlae with the poorer prognosis of breast cancer in young patients. We conclude that early screening examination is helpful for early detection of breast cancer in women under age 35.

OBJECTIVES: The aim of this study was to investigate the relationship between the contributions of macronutrients to the total energy intakes and Body Mass Indices (BMI, kg/m2) of Korean women. METHODS: We used dietary records data from 115 healthy Korean women, ages 20 and over, who completed four 3-day dietary records between February 2003 and March 2004. For the calculation of nutrients we used a dietary assessment program developed by the Korean Nutritional Society. Macronutrient intakes were estimated by averaging individual total daily intakes in four 3-day dietary records. Subjects were categorized into three Body Mass Index (BMI) groups: underweight (BMI<20), normal (20< or =BMI<25), and overweight (BMI> or =25) group. RESULTS: The total energy intakes were not different among the three BMI groups. Similarly, other macronutrient intakes such as protein, fat, carbohydrate, vegetable protein, animal protein, saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids were not different. From the multivariate nutrient density model, substituting polyunsaturated fatty acid for carbohydrate was positively associated with BMI in women aged 20 to 49 (beta=2.31, p<0.01). In women aged 50 and over, substituting animal protein for carbohydrate was positively associated with BMI (beta=0.549, p=0.04). CONCLUSIONS: No single macronutrient was associated with BMI when all subjects were combined. However, when stratified by age, polyunsaturated fatty acid intake in younger women, and animal protein intake in older women, were positively associated with BMI. In the future, we recommend a larger study to confirm these results.

BACKGROUND: Exercise-stress electrocardiography (ECG) is initially recommended for the diagnosis of coronary artery disease. But its value has been questioned in women because of suboptimal diagnostic accuracy. Stress echocardiography had been reported to have comparable test accuracy in women. But the data comparing the diagnostic accuracy of exercise-stress ECG and stress echocardiography directly are few. The aim of the study was to compare the diagnostic accuracy of exercise-stress ECG and dobutamine stress echocardiography (DSE) in Korean women. METHODS: 202 consecutive female patients who presented with chest pain in outpatient clinic, and who underwent treadmill exercise test (TET), DSE and coronary angiography were included for the study. The diagnostic accuracy TET and DSE were calculated by the definition of > 50% or > 75% coronary artery stenosis (CAS). RESULTS: The sensitivity and specificity were higher with DSE (70.4, 94.6%) than TET (53.7, 73.6%) for detection of > 50% CAS. The higher accuracy of DSE was maintained after exclusion of the patients who could not achieve over 85% age predicted heart rate before ischemia induction. DSE also showed greater diagnostic accuracy than TET by > 75% CAS criteria, and in subsets of patient with intermediate pretest probability. CONCLUSION: In the diagnosis of CAS, DSE showed higher accuracy than TET in female patients who presented with chest pain. As well as the test accuracy, adequate stress was more feasible with DSE than TET. These finding suggests DSE may be used as the first-line diagnostic tool in the detection of CAS in women with chest pain.

Garcin's syndrome is defined as showing total unilateral cranial nerve palsies (at least more than 7 ipsilateral cranial nerve palsies), without either sensory or motor long tract disturbance, and without intracranial hypertension. The present report describes an 8-year-old child who had swelling on the right postauricular area and ptosis on the same side which developed before 2 months ago. Neurologic examination disclosed complete unilateral cranial nerve palsies on the right side. Brain MRI revealed a bulky hypervascular well-enhancing solid tumor, involving the right temporal bone, middle cranial fossa, cerebellopontine angle, infratemporal and pterygopalatine fossae, and parapharyngeal space. A biopsy was performed, and its finding showed a chondrosarcoma.

Background: Whole body scan using 131-iodine is performed to detect local recurrence or metastasis after thyroidectorny in differenciated thyroid cancer patients. The sensitivity of this procedure is related to the dose of radiopharmaceutical administered. It was reported that 131I posttreatment whole body scan demonstrate foci of tracer uptake not previously observed in diagnostic scan in 10~30% of cases. Posttreatment scans were most likely to reveal new foci in young patients(<45) and patients who had previously received radioactive iodine therapy. Method: We observed the frequency of discordant posttreatment scans and analysed the clicnical significance in 33 differenciated thyroid cancer patients who were admitted for radioiodine ablation from June, 1995 to April, 1996. Results: In 7 cases(21.2%), post treatment scan demonstrated cme or more foci of uptake and revealed less sites of uptake than diagnostic scan in 3 cases(9.1%). In one case with elevated thyroglobulin level and negative diagnostic scan, post treatment scan revealed new uptake sites with thyroid bed and cervical 1ymph node. The sites of discordant uptake were cervical lymph nodes in 4 cases and rnediastinal lymph node in one case, lung in one case, thyroid bed and cervical lymph nodes in one case, 3 cases of 7 pts(43%), demonstrated ane or more foci of uptake in post treatment scan, had history of previous radioiodine treatent. Conclusion: Post treatment scan confirmed uptake into remnant and metaststic tissues identified on the corresponding low dose diagnostic scans. Scanning after high dose radioiodine treatment frequently demonstrated one or more foci of uptake, especially in patients with previous radioiodine treatment, which were not visualized on the diagnostic low dose scan. Treatment scan may be useful for detection of remnant tissue or metastatic lesion in patients with elevated thyroglobulin and negative diagnostic scan.
