The purpose of this study is to verify severity of asthma in asthmatic patients through through the arterial blood gas analysis. Subjects were consisted of 103 patients (74 boys and 29 girls), between 2~13 years of ages. Clinically, asthmatic patients were classified into 6 groups, i, e., group 0(no rhonchi), group 1(rhonchi only), group 2(mild attack), group 3(moderate attack), group 4(severe attack), group 5(respiratory failure with disturbance of consciousness). PH kept normal range in the group 0, group 1, group 1 and group 3,but began decrease in the group 4.There was linear fall in Po2 and began decrease in the group 3. HCO3- maintained normal level through the whole range. BE showed acidemia on the whole, and began distinctive decrease in the group 4 and group 5, especially. Hypoxemia, hypercapnia and acidemia were common in patients in severe attacks with disturbance of consciousness.

PURPOSE: It may be difficult to differentiate renal cell carcinoma involving collecting system from renal urothelial tumor invading into renal parenchyma. The purpose of this study was to assess the differences of CT findings between two conditions. MATERIALS AND METHODS: CT findings of 5 cases of renal cell carcinoma involving the renal collecting systems and 10 cases of renal urothelial tumors invading the renal parenchyma were compared, and analyzed about the presence or absence of hydronephrosis, normal or abnormal CT nephrogram, renal contour changes due to mass and tentative diagnosis. The diagnoses were confirmed at surgery. RESULTS: Renal cell carcinoma showed hydronephrosis in only 20% and normal CT nephrogram and outward contour bulging in all cases. In contrast, renal urothelial tumor showed hydronephrosis(70%), abnormal CT nephrogram(60%), and preservation of reniform shape(100%). CONCLUSION: Renal contour changes and CT nephrogram may be useful in distinguishing both disease entities.

PURPOSE: To identify the clinical features with recurrence of amblyopia after cessation of amblyopic treatment. METHODS: Amblyopic children followed up at least 1 year after successful treatment were evaluated. A recurrence of amblyopia was defined as a reduction of more than 2 levels in visual acuity (VA) of the amblyopic eye after cessation of treatment. The age and VA of the amblyopic eye at the start and during follow-up, type of amblyopia, type and duration of treatment, weaning and stereopsis on cessation of treatment were analyzed. RESULTS: Amblyopia recurred in 5 out of 82 patients with successful treatment, and the period of recurrence varied from 7 to 31 months after cessation of treatment. Two out of 5 recurred patients had only patching therapy and the other 3 patients had atropine penalization after patching therapy. The weaning was performed in the 5 recurred patients at cessation of treatment. There was no remarkable clinical factor associated with recurrence of amblyopia. CONCLUSIONS: The recurrence rate was 6% after cessation of amblyopic treatment and there was no factor associated with recurrence of amblyopia. Therefore, regular follow-up may be required after successful treatment for amblyopia.

A study on objective personality characteristics of 41 central serous chorioretinopathy patients was performed to investigate the etiologic relationship of psychological behaviors about the central serous chorioretinopathy. Fourty-one healthy subjects were used as a control group. Authors used the Minnesota Multiphasic Personality Inventory (MMPI) which consisted of 4 validity scales and 10 clinical scales. Three neurotic scales of hypochondriasis, depression and hysteria in the atients group were significantly higher than in the normal control group even though the mean scores on each clinical scale were within normal ranges in both groups.

We experienced two cases of occupational asthma induced by Elk dander in Elk-feeders and confirmed these cases by the bronchial provocation test with Elk dander. Both of them showed dual asthmatic response. They also showed positive reaction to the skin prick test with EIK dander. Now one of them has no asthmatic symptoms at all after complete avoidnce of EIK dander.

The clinical utility of thallium-201 SPECT combined dwith pharmacologic vasodilation induced by oral dipyridamole as an alternatiove to intravenous dipyridamole was incestigated in 21 patients who had concomitant coronary arteriography. Tomographic images were assessed visually. Sensitivity & specificity for overall detection of coronary artery disease were 93.7% and 80% respectively. Sensitivity & specificity for identification of indevidual diseased vessels were 84.6% and 87.5% for the left anterior descending artery, 75% and 84.6% for the right coronary artery, 60% and 100% for the left circumflex artery, respecitively. Of the 26 patients unergoing thallium scintigraphy 11 patients(42.3%) had some adverse effects between 20 and 50 minutes after oral dipyrdamole ingestion, including headache(26.9%), chest pain(26.9%), electrocardiographic changes(19.2%), and nausea(11.5%). Intravenous aminophylline was used to resolve these adverse effects in 8 patients & most of the adverse effects were subsided within 10 minutes. There was no ventricular arrhythmias, myocardial infarctions or deaths. In conclusion, oral dipyridamole thallium-201 SPECT is safe and accurate test for the overall detection of coranary artery disease and identification of disease in individual arteries. Furthermore it is useful for determining the necessities of coronary reperfusion and prognstically stratiofying the patients with coronary artery disease.

OBJECTIVE: The aim of the present study was to investigate the visual perception difference between ADHD children with and without sensory processing disorder, and the relationship between sensory processing and visual perception of the children with ADHD. METHODS: Participants were 47 outpatients, aged 6-8 years, diagnosed with ADHD. After excluding those who met exclusion criteria, 38 subjects were clustered into two groups, ADHD children with and without sensory processing disorder (SPD), using SSP reported by their parents, then subjects completed K-DTVP-2. Spearman correlation analysis was run to determine the relationship between sensory processing and visual perception, and Mann-Whitney-U test was conducted to compare the K-DTVP-2 score of two groups respectively. RESULTS: The ADHD children with SPD performed inferiorly to ADHD children without SPD in the on 3 quotients of K-DTVP-2. The GVP of K-DTVP-2 score was related to Movement Sensitivity section (r=0.368*) and Low Energy/Weak section of SSP (r=0.369*). CONCLUSION: The result of the present study suggests that among children with ADHD, the visual perception is lower in those children with co-morbid SPD. Also, visual perception may be related to sensory processing, especially in the reactions of vestibular and proprioceptive senses. Regarding academic performance, it is necessary to consider how sensory processing issues affect visual perception in children with ADHD.

Since 1931, sporadic reports have appeared noting an apparent association between hyperthyroidism and idiopathic thrombocytopenic purpura. Recent various studies suggested that these two diseases may share a similar immunologic background, but the exact mechanism is still a matter of speculation. This 22-year-old female patient visited this hospital because of general weakness and purpura of legs for 2 months. The laboratory findings were compatible with Graves' disease associated with idiopathic thrombocytopenic purpura. The platelet count was 16000/mm³, hemoglobin was 10.9 g/dl and MCV was 60.1fL. T3 was 490.53 ng/dL, T4 was 24 ug/dL and free T4 was 5.66 ng/dL. Antiplatelet antibody and antimicrosomal antibody were positive. The bone marrow findings were compatible with iron deficiency anemia and idiopathic thrombocytopenic purpura. The thyroid biopsy showed adenomatous goiter. She was administered with propylthiouracil, Beta-blocker, iron and prednisolon. On the 10th hospital day, platelet count was 184000/mm³, hemoglobin was 12.0 gm/dL and MCV was 67.5 fL. On the 20th hospital day, T4 was 10.35 ug/dL and free T4 was 2.30 ng/dL. Therefore she was discharged and followed up.

PURPOSE: To study the effects of subconjunctival injection on the conjunctiva and muscles after muscle resection in a rabbit model. METHODS: Resection surgery of 5 mm was performed on both the superior rectus muscle (SR) and the inferior rectus muscle (IR) in five white rabbits. As such, 2.5 mg bevacizumab was subconjunctivally injected around the right SR and IR in the experimental group. The left eyes were not injected and were instead used as the control group. The degrees of injection and edema of conjunctiva were classified on a scale from 0 to 4 via gross examination by five examiners at two and four weeks after surgery. The strength of the muscle attachment was assessed, and the degrees of conjunctival inflammation and inflammation and fibrosis of the muscle were classified on a scale from 0 to 4 at four weeks after surgery via histologic examination. RESULTS: The results of gross examination at two and four weeks after surgery showed positive correlation among the five examiners (k=0.52, k=0.4), although there was no statistically significant difference between the experimental and control groups (p=0.285, p=0.364). There was also no significant difference between the two groups with regard to tensile strength of the attachment (p=0.414), inflammation of the conjunctiva and muscle, or fibrosis of the muscle in histologic examination (p=0.698, p=0.702, p=0.232, respectively). CONCLUSIONS: There were no significant effects on the inflammation and fibrosis of the conjunctiva or muscles due to subconjunctival injection of 2.5 mg of bevacizumab after muscle resection in a rabbit model.
