This is the clinical statistics concerning the admissions in the Pediatric Department of the Chosun University Hospital during the past 5 years from Jan. 1975 to Dec. 1979. All the patients were classified by y Classification of Disease by W.H.O. The Obtained results are as follows: 1. Total number of admission during 5 year period were 3249 cases, of which 2121 cases (65.28%) were male, 1128 cases (34.72%) were female and male to female ratio was 1.88:1. 2. The number of patients were increased every year gradually. 3. On age group, Infancy age group was the most frequent group, 714 cases (22%), followed by School age group, 6679 cases (20.9%) and Preschool age group, 679 cases (20. 9% ) in the order of frequency. 4. On monthly distribution, there was the more admission in the September and the Autumn on season, 5.

With the availability of the method of analysis of serum protein using minute amounts of material, it was felt desirable to understand the protein metabolism and physiologic function in the body. The present study was undertaken to clarify the serum albumin, globulin and total protein at term to demonstrate the normal concentration and correlation between the 30 mother and newborn infant pairs. Serum albumin, globulin and total protein were determined by the Biuret method with pooled human serum. The A/G ration was calculated by formula of A/G. The following result were obstained. 1) In comparing the newborn infants of nonanemic mothers a albumin and total protein concentrations were higher and globlin concentrations decreased in the anemic mothers. 2) In comparing the nonanemic mothers and anemic mothers the mean albumin concentrations were nearly equal but globulin and total protein were slightly increased in the nonanemic mothers. 3) The mean serum albumin(of maternal and umbilical cord blood) was 3. 8+/-0. 35 gm/100 ml and 3. 8+/-0. 49 gm/100 ml respectively. 4) The mean serum globulin of mate. nal and umbilical cord blood was 2. 7+/-0. 41 gm/100 ml and 2. 32+/-0. 47 gm/100 ml respectively. The correlation of the globulin status between mot-hers and their newborn infants was not significant(r=0. 32). 5) The m-an serum total protein of maternal and umbilical cord blood was 6. 59+/-0. 59 gm/100 ml and 6. 02+/-0.57gm/100ml respectively.

We studied to investigate the predictive values of gated SPECT for the improvement of wall motion after bypass surgery. As we compared postoperative SPECT with preoperative ones, we defined viability as wall motion improvement. We performed rest T1-20l/stress Tc-99m-MIBI gated SPECT in 25 patients before and 3 months after bypass surgery. Myocardial wall motion was graded as normal, hypokinesia, a kinesia, and dyskinesia by pair-wise visual analysis of gated pre and postoperative SPECT's on the same monitor wall motion abnormalities before operation, 69 (75%) improved and 23 did not. Before operation, we could find segments with good systolic thickenining 64 segments among total 92. Thickening of the remaining 28 was poor. Wall motion improved postoperatively in 45 segments (70%) among 64 with good thickening, Twenty four(86%) among 28 segments with poor thickening had also improved. We grouped segments into mild(hypokinetic) and severe(akinetic/dyskinetic) ones. Among 33 segments with severe motion abnormalities, 14 had good thickening and 19 did not. Nine(60%) improved out of 14 segments having severe abnormality with good thickening. However, 16(84%) segments out of 19 having severe abnormality with poor thickening also improved. Neither degree of perfusion decrease nor severity of wall motion abnormalities could explain the high rate of false negatives. In conclusion, as we defined viability as wall motion improvement by comparing pre and postoperative SPECT, systolic thickening observed by gated Tc-99m-MIBI SPECT in myocardial segments with wall motion abnormalities predicted wall motion improvement after bypass surgery. However, poor thickening could not be referred as evidence of nonviable myocardium both in mild and severe contractile dysfunction, so that we might need stimulation study such as dobutamine echocardiography or dobutamine gated SPECT.

OBJECTIVE: Although there are several explanations for a duplicated middle cerebral artery (DMCA), its embryological origin is still an open question. We reviewed these anomalous vessels to postulate a theory of their different origins, sizes, and courses. METHODS: A retrospective review of 1,250 cerebral angiographies, 1,452 computed tomography (CT)-angiographies, and 2,527 magnetic resonance (MR)-angiographies was performed to identify patients with DMCA. RESULTS: Twenty-five patients had 25 DMCAs. Conventional angiography detected nine patients with DMCA (9/1250, 0.72%), MR-angiography detected seven patients with DMCA (7/2527, 0.28%), and CT-angiography detected nine patients with DMCA (9/1452, 0.62%). The DMCAs originated near the internal carotid artery terminal in eight patients (type A), and between the origin of the anterior choroidal artery and the terminal internal carotid artery in 17 patients (type B). The diameters of the eight type A DMCAs were the same or slightly smaller than those of the other branch of the DMCA. All type A DMCAs showed a course parallel to that of the other branch of the DMCA. The diameters of the 17 type B DMCAs were the same, slightly smaller, or very much smaller than that of the other branch of the DMCA. Nine type B DMCAs showed parallel courses, and the other eight curved toward the temporal lobe. CONCLUSION: The two branches of the type A DMCAs can be regarded as early bifurcations of the MCA. The branches of the type B DMCAs had parallel courses or a course that curved toward the temporal lobe. The type B DMCA can be regarded as direct bifurcations of the MCA trunk or the early ramification of the temporal branch of the MCA.

STUDY DESIGN: Case report OBJECTIVES: We report a case of relatively rare multiple bilateral perineural cysts. SUMMARY OF LITERATURE REVIEW: Tarlov cysts, also known as perineural cysts are most often found in the sacral region, but there are a few cases reported in the thoracic region. In particular, there are very few cases of multiple bilateral thoracic perineural cysts. MATERIALS AND METHODS: A woman aged 65 years with perineural cysts in the bilateral T10-T11 and T11-12 neural foramens, underwent a T10-11-12 decompressive laminectomy and resection of the cyst. RESULTS: Satisfactory results were obtained for the patient after surgery. CONCLUSIONS: For more detailed and definitive treatment of thoracic perineural cysts, additional cases are required.

Splenic abscess is an uncommon but frequently fatal condition. Signs and symptoms are variable and do not always include left upper quadrant pain or tenderness. Unexplained thrombocytosis in a septic patient with persistent left pleural effusion is suggestive of splenic abscess. We report a case of splenic abscess with complicated multiple fistulas by Klebsiella pneumoniae which was successfully managed by antibiotic therapy, and percutaneous catheter drainage.

PURPOSE: Dipyridamole stress myocardial perfusion SPECT could predict prognosis, however, long-term follow-up showed change of hazard ratio in patients with suspected coronary artery disease. We investigated how long normal SPECT could predict the benign prognosis on the long-term follow-up. MATERIALS AND METHODS: We followed up 1169 patients and divided these patients into groups in whom coronary angiography were performed and were not. Total cardiac event rate and hard event rate were predicted using clinical, angiographic and SPECT findings. Predictive values of normal and abnormal SPECT were examined using survival analysis with Mantel-Haenszel method, multivariate Cox proportional hazard model analysis and newly developed statistical method to test time-invariance of hazard rate and changing point of this rate. RESULTS: Reversible perfusion decrease on myocardial perfusion SPECT predicted higher total cardiac event rate independently and further to angiographic findings. However, myocardial SPECT showed independent but not incremental prognostic values for hard event rate. Hazard ratio of normal perfusion SPECT was changed significantly (p<0.001) and the changing point of hazard rate was 4.4 years of follow up. However, the ratio of abnormal SPECT was not. CONCLUSION: Dipyridamole stress myocardial perfusion SPECT provided independent prognostic information in patients with known and suspected coronary artery disease. Normal perfusion SPECT predicted least event rate for 4.4 years.
