Anaphylactoid nephritis is a disease complicated by anaphylactoid purpura manifested by a non-thrombocytopenic purpura, abdominal pain. And joint pain The manifestation of nephritis may vary from microscopic hematuria to acute rapidly progressive nephritic and nephrotic syndrome. This paper reports on anaphylactoid nephritis in children. These cases were collected fromthe Department of Pediatrics, Yonsei university Medical College from January 1,1974 to may 31, 1979. The results are as follows; 1. Among 75 cases of anaphylactoid purpura, 25 cases developed nephritis(33%), 16 cases were male and 9female. The age distribution was from 3years 5months to 15years. The peak incidence occured between 5 and 7years ofage with 11 cases. 2. The evidence of renal invovement in 18 cases among 25 were detected within 4 weeks after onset of skin manifestation. 3. The clinical manifestations were skin rashes, abdominal pain, joint pain, pitting edema, gross hematuria, and melena in orders. 4. The clinical classification of renal involvement were transient hematuria 4 cases, acute nephritis, 7 cases recurrent hematuria 1 case, nephrotic syndrome 5 cases, and undetermined 8 cases. 5. In additionto the usual signs of renal involvement, serum levels of IgA were checked. The elevation of IgA was 4 cases among the tested 6 cases. 6. According to the pathologic findings and immunofluorescent technique, 8 cases out of 9 cases by kidney biopsy were focal proliferative glomerulonephritis and 1 case diffuse proliferative flomerulonephritis. The deposit of glomeruli by immunofluorescent technique was IgA, IgG, IgM, and fibrin 7. All the cases were treated with prednisone and only 4 cases were combined with immunosuppressant, azathioprine without benfit.

Chyle is the digestive product absorbed from intestinal lymphatics which the component have high concentration of triglyceride and protein. The various pathological circumstances which give rise to intrathoracic effusion of chyle are well documented and so the etiology is clearly defined in most instances. However, the occurrence of chylothorax in early infancy, in the absence of other demonstrable diseases and without apparent birth trauma, suggests the existence of congenital malformation of the thoracic ducts. We lately experienced a 20 day old new born who was proved to have congenital chylothorax by clinical history and laboratory findings. So we report the clinical findings and laboratory findings with the review of the literatures on congenital chylothorax.

OBJECTIVES : The aim of this study was to identify the characteristic symptoms for diagnosis of Hwabyung (HB), a culture-related anger syndrome in Korea; to construct a rating scale for HB and test its validity and reliability; and propose diagnostic criteria for HB. METHODS : Subjects were male and female Korean patients, who were diagnosed following Structured Clinical Interview (SCID) as having depressive disorders, anxiety disorders and somatoform disorders and who reported as having self-labeled HB. A HB Scale was constructed with 22 of the most common symptoms of HB as identified by previous studies. The HB scale's inter-rated reliability was tested with 60 subjects. Its validity was tested by comparison between a HB only group(n=47) and depressive disorder only group (n=44). Logistic regression analysis was conducted to make a predictive model of HB. Based on these results diagnostic criteria for HB was proposed. RESULTS : Inter-rated reliability in each of all the items and the total score of the HB Scale were statistically significant. The HB scale differentiated HB from depressive disorder with statistical significance. In logistic regression analysis, the ability of the HB model to predict symptoms of heat sensation, ukwool/boon (feeling of unfairness), and subjective anger was high with sensitivity of 80.0%, specificity of 88.4%, accuracy of 84.1% and area under ROC of 0.92. Based on these results and information from previous research, diagnostic criteria of HB were formulated. CONCLUSION : The HB Scale was found to be reliable and valid. Consequently, diagnostic criteria of HB were proposed, to include subject anger, "kwool/boon" (Feeling of unfairness), expressed anger, heat sensation, hostility, "haan", pushing-up in the chest, epigastric mass, respiratory stuffiness, palpitation, dry mouth, sighing, racing thoughts, and lamentation.

Recently, techniques of magnetic resonance angiography(MRA) have been developed that permit a three dimensional display of vessel without infusion of a contrast agent. However, to be competitive with conventional angiography(CA). MRA should show not only morphology of vessel but should also provide functional inforrnation, as selective delineation of specific vascular territories. Selective presaturation of individual vessels causes signal loss within the territory supplied by the presaturated artery, without affecting vessels not crossing the presaturation slab. We applied the selective MRA to the study of blood flow dynamics in five patients wiih ischemic stroke, showing patent middle cerebral arteIy in spite of obstruction or severe stenosis of the ipsilateral internal carotid artery on MRA. Selective MRA was able to demonstrate the direction of blood flow and presence of collateral blood flow. Findings of selective MRA were correlated with those from CA. Selective MRA can be used as a noninvasive and useful means for imaging the blood supply of the major intracranial arteries.

PURPOSE: To investigate the relationship between the smart devices usage-related factors and self-regulation ability development in early childhood. METHODS: Parental questionnaires of 187 children aged 3–6 years were analyzed. The metrics included smart device usage frequency (times/week, scored as uFreq), smart device usage time (hours/day, scored as uTime), parental scale for appropriate smart device usage level (scored as uLevel), the Korean-developmental screening test (K-DST), and the scale for self-regulation ability in young children (scored as SRS, and including four sub-categories: self-appraisal, self-determination, behavior inhibition, and emotionality). The correlations were analyzed by total age group and by each age. RESULTS: In the total age group analysis, uFreq and uTime were negatively correlated with mean SRS (rs =−0.366, −0.330; P < 0.001) and sub-category SRS (rs =−0.186 to −0.370; P < 0.05). Mean uLevel score was positively correlated with mean SRS (rs =0.406; P < 0.001) and most of the mean sub-category SRS (rs =0.174 to 0.362; P < 0.05). In 3-year-old children, the mean SRS was strongly negatively correlated with uFreq (rs =−0.751; P < 0.001), negatively correlated with uTime (rs =−0.518; P < 0.001), and positively correlated with mean uLevel score (rs =0.533; P=0.013). Such correlations seemed to decrease at the age of 4–6 years. CONCLUSION: Self-regulation ability was significantly correlated with smart device-related factors and was the highest in the 3-year-old children. Encouraging appropriate smart device usage will be helpful for self-regulation development of young children.

PURPOSE: To observe the pattern of glue cast formation when glue was injected into the different fow layersof a flow phantom, and to demonstrate the effect in an animal experiment. MATERIALS AND METHODS: A flow phantom model consisted of a circulating pump (Simon varistaltic pump, Manostat Corporation, U.S.A.) connected via a tygon tube with a specially designed glass tube. Flow of about 4ml/sec was maintained by saline. The glass tube consisted of (1) a small-caliber (2.4-3.2mm inner diameter) straight inflow portion (feeder), (2) a round, larg-caliber portion (nidus), and (3) a medium-caliber (6.7mm inner diameter) straight outflow portion (vein). Glue mixed with Lipiodol (glue: Lipiodol=1:1-3:1) was loaded into a 1cc syringe and slowly injected through a microcatheter ; cast formation along the glass tube was observed. The feeder and nidus portions were injected twelve times and the shape of the cast was compared. In an animal experiment, glue at various concentrations was used to stop rapid flow through a surgically-constructed arteriovenous fistula in porcine carotid artery. RESULTS: When mixture was injected into the straight inflow portion (1), it formed a cast along the wall of the glass tube, with a large cast in the nidus portion. Further injection caused enlargement of the cast in the nidus, but no change in the wall of the inflow portion. When mixture was injected into the nidus portion (2) of the glass tube, a cast formed continuously within the nidus. In the animal experiment, rapid injection of glue at a high conentration staunched flow through the arteriovenous fistula. CONCLUSION: Glue-Lipiodol mixture can be injected slowly and continuously under the surface of the polymerized glue cast which forms along the wall or slow flow portion (nidus) of the glass tube in an experimental flow phantom. However, the effect did not appear during rapid flow in the animal arteriovenous fistular model in which only rapid injection of glue which was either pure or at a glue concentration of more than 75% was effective.

A 68 year old male with diabetes mellitus visited our hospital due to general weakness and abdominal pain. Patient was in severe septic condition, abdominal X-ray and CT revealed gas shadow on left kidney and bladder. E-coli grew on urine culture. Thus we were able to diagnose the patient as the emphysematous pyelonephritis with emphysematous cystitis. The patient was treated with antibiotics and bilateral bladder catheter drainage. However the patient expired due to severe sepsis. Although the emphysematous pyelonephritis and emphysematous cystitis are rare disease, they result in life threatening complication in diabetic patients. Because of rarity of these diseases, the clinical and radiological classifications, the treatment and the progress are not established. These two diseases have the same causes such as diabetes mellitus or urinary tract obstruction and can be expanded due to anatomical relationships resulting in increased mortality. The authors report 68 year old male diabetic patient with emphysematous pyelonephritis with emphysematous cystitis with literature review.

OBJECTIVE: The study aims were to demonstrate apoptosis in the placenta of normal pregnancy, and to identify its change and quantify its incidence by gestational age. METHODS: Placenta samples were collected from 25 normal full-term pregnancies and 20 second trimester pregnancies undergoing termination due to medical and social reasons. Hematoxylin and eosin staining and TUNEL (terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling) staining were used to quantify the incidence of apoptosis and the electron microscopy was used to confirm it. Mann-Whitney U test and ANOVA test were used for statistical analysis. RESULTS: 1. Apoptosis was demonstrated by variable cytopathologic methods, and especially TUNEL staining and electron microscopy are found to be confirmatory methods. 2. In TUNEL staining, quantification of apoptosis was as follows: 2nd trimester (n=20) 1.05+/-0.69, full- term (n=25) 1.92+/-1.00. The incidence of apoptosis was significantly higher in full-term than in 2nd trimester (p<0.05, Mann-Whitney U test). 3. In hematoxylin and eosin staining, quantification of apoptosis was as follows: 2nd trimester (n=20) 0.40+/-0.50, full-term trimester (n=25) 0.72+/-0.61. The incidence of apoptosis was not significantly higher in full- term trimester than in 2nd trimester (p>0.05, Mann-Whitney U test). 4. There was no statistical significance in the incidence of apoptosis by maternal age, parity, cause of termination during 2nd trimester, and mode of delivery in each group. 5. In the electron microscopy, apoptotic cells were observed to have membrane blebbing, loss of microvilli, chromatin condensation and localization in the border of nuclear membrane, and cell shrinkage and increase in granularity. This method was conformatory in identifying apoptosis. CONCLUSION: Placental apoptosis increased significantly with increased gestational age, and this result suggests that it may play a role in the normal development and aging of the placenta.

OBJECTIVE: We studied the effect of Hyu-Sig-Gong-Gan and Hye-Ah-Rim on several evaluations and compared the two programs. We then investigated factors associated with the difference between pre- and post-ratings. METHODS: Thirty-six patients were randomized to Hyu-Sig-Gong-Gan (n=23) or Hye-Ah-Rim (n=13). We tested for the effect of each program on several evaluations and compared the two programs through Zarit Burden Interview (ZBI), Center for Epidemiologic Studies-Depression Scale, Dementia Attitude Scale (DAS)-intelligence, DAS-comfort and DAS-total. We then investigated whether the difference between pre- and post-rating depends on other factors. RESULTS: We observed significant positive effect of Hyu-Sig-Gong-Gan on DAS-comfort (t=1.843, p=0.039) and significant positive effect of Hye-Ah-Rim on ZBI (t=-2.327, p=0.019), DAS-comfort (t=2.241, p=0.022), and EuroQol-5 Dimensions-Visual Analogue Scale (t=2.537, p=0.013). For comparing the two programs, we found a lack of evidence for the difference in any of the five commonly observed evaluations. In the secondary analysis, we observed a strong trend that the two programs were particularly effective for caregivers with negative pre-ratings. CONCLUSION: The two programs showed positive effects on the various evaluations, but some evaluations could not reach statistical significance. The programs appear to be particularly helpful for those who are in need before the program participation.
