Traditionally, it has been emphasized that hemolytic disease was the primary cause of gallstones (cholelithiasis) in most young patients. In recent years, gallstones and common bile duct calculi have been increasingly diagnosed in infants and children, unrelated to hemolytic diseases. On the matter, the World Health Organization (WHO) classified intraepithelial neoplasia (dysplasia) of gall bladder as one of the precursor lesions of invasive cancer. The following article describes the case of a 2-year-old girl who had a laparoscopic cholecystectomy due to cholelithiasis and the pathologic diagnosis was chronic cholecystitis with diffuse, mild mucosal dysplasia.

During general anesthesia, removal of exhaled carbon dioxide by rebreathing appliances is provided by chemical absorption and this carbon dioxide absorption during anesthesia would at first glance seem to be a simple problem. The problem, however, is far more complicated and much attention must be given to details of rebreathing appliances. Incomplete removal of carbon dioxide in circle absorber systems, which are commonly used today must be carefully monitored to prevent hypercapnea caused by accumulation of carbon dioxide in the breathing circuits. Although circle absorbers have been developed through clinical trials anesthesiologists have no reliable indication of the end point of useful life of the absorbent. This study was undertaken to investigate the useful life of the soda lime used in two type of canisters (type A: canister of anesthesia machine. Quantiflex, USA. 12.9cmX16.6cm, tbye B: canister of anesthesia machine, International 2. U.K., 13.1cmX16.9cm). the effect of flow rate on this useful life and the relations between indicator change and the endpoint of useful life of the soda lime. The control group used a as total flow rate of fresh gases at 2.0 liters per minute and the experimental group used a total flow rate of 4.0 liters per minute. The carbon dioxide concentration of 0.1% at the canister exit was employed as the end point of useful life of the absorbent and the exit carbon dioxide concentration were monitored continuously by intra-red carbon dioxide monitor apparatus(Datex Normocap CD-102, Pinland). Also the carbon dioxide concentration in the respiratory circuit of exhaling side was examined. The results were as follows: 1) In type A, the average useful life of soda lime was 1,885 minutes in the control group and 2,514 minutes in the experimental group. In type B, the average useful life of soda lime was 1,587 minutes in the control group and 1,980 minutes in the experimental group. 2) At the end point of useful life of the absorbent the level of the color change of the indicator of the absorbent in all types was above the three-fourth height of two chambered canister. 3) At the end point, end tidal CO2 concentration was 3.5 vol% in the control group 2.88 vol% in the experimental group. The data obtained from this observation indicated that the increase of total flow rate of gas and the type A canister prolonged the useful life of soda lime and that the double chambered canister could be used safely until the color change of the indicator reached the level of three fourth the height of the canister.

PURPOSE: The recurrence of Kawasaki disease has not been considered significant and has not been reported on literatures in Korea. Authors reviewed cases with recurrent Kawasaki disease to get informations about recurrent Kawasaki disease and to know whether there is any factor, if present, that can predict recurrence. METHODS: We reviewed and analyzed the hospital records of patients with recurrent Kawasaki disease who had been admitted to Inha University Hospital from January 1986 through December 1994. RESULTS: The total number of cases with Kawasaki disease was 266 during that period in Inha University Hospital. Seven patients were diagnosed as having recurrent Kawasaki disease, but four of them fulfilled five or more items of the diagnostic criteria for Kawasaki disease. So the proportion of recurrent cases was 1.5%(4/259)(or 2.7% (7/259) ?). Sex ratio was M:F=3:1. The ages at the first episodes of illness were from 7 months to 3 years 2 months (median=24 months), and those of the second episodes were from 11 months to 6 years 3 months (median=4 years 3 months). The intervals between two episodes were from 4 months to 4 years 2 months (median=1 year 9 months). No special aspect could be found in the clinical and laboratory findings of primary cases, compared with other cases with kawasaki disease. The clinical manifestations and courses of recurred cases were not significantly different from those of primary cases, except one recurred case who developed coronary aneurysm. CONCLUSIONS: The recurrence rate of Kawasaki disease seems to be higher than 1.5%(or 2.7%) at least. The risk factors for recurrence could not be found, and there was no specific aspect in the clinical manifestations and courses of recurrent Kawasaki disease.

Idiopathic myelofibrosis (IMF), which is characterized by marrow fibrosis, leukoerythroblastic anemia, teardrop poikilocytosis and splenomegaly due to extrumedullary hematopoiesis, has known to have no form of therapy. On the ground of the possibility of reversing collagen deposion in IMF using 1, 25dihydroxycholecalciferol [1, 25(OH)2D3], we report here our observations of 5 patients (M:F=1:4) with IMF before and after treatment with 0.5 microgram/day of alfacalcidol, precursor of 1, 25(OH)2D3. In 3 fo 5 patients the hemoglobin rose and in 4 of 5 the platelet count increased. Follow-up marrow examination revealed that marrow trephine reticulin fibrosis decreased according as the amelioration of clinical and laboratory findings. But these did not persist except one patient in spite of the sustained use of alfacalcidol. Our results suggest that alfacalcidol may have a therapeutic role in some patients with IMF. More extensive studies will be clarify the action of alfacalcidol in IMF.

Pulmonary function test is one of the most important tools in the management of patients with respiratory tract diseases and allergic diseases. As with the difficulties in performing the test, it has been seldom used in pediatric field. But with the advent of simple, computerized tools, pediatric pulmonologist and allergist try to manage the patients using PFT. Still the normal predicted values are variable among the reports. So it is important to have normal predicted value in Korean children. From April to July 1992, pulmonary function test was performed in 965(male: 490, female: 475) primary school-aged children except <3 or >97 percentile of Korean-children Physical developemental standards with history of allergic diseases and respiratory tract diseases ay SungNam, KyongKiDo. We evaluated the predicted normal values of the FEV1.0, FVC and PEFR and logarithmic regression equation setting the predicted values by using the microspirometer of Micromedical Ltd. England that could that could be easily applied to children. 1) Predicted values of pulmonary function test items were generally higher in boys than those of girls. 2) Correlation coefficient to the parameters examined was the highest in height 0.78, then age 0.75, weight 0.70 and chest circumference 0.61.

We herein report two patients with epidermolysis bullosa acquisita(EBA), who had showed the atypical clinical features. A 25-year-old male presented with multiple pruritic vesicles, erosion and crusts which occurred more severely on the face than any other sites of the skin and healed with atrophic scar formation. Histopathologically, there was a subepidermal neutrophilic blister with moderate perivascular lymphohistiocytic infiltrates in the dermis, and the diagnosis of EBA was confirmed by means of direct immunofluorescence and salt-split direct immunofluorescence test performed on the perilesional skin. The other patient was a 24-year-old female who had had multiple painful ulcerative lesions on the oral mucosa for 4 months. After then, vesicles and bullae developed to progressively generalize to the anterior neck, chest and lower leg. Histolopathologic examination of peribullous skin showed a subepidermal bulla with neutrophils and eosinophils. The salt-split skin direct immunofluence test showed IgG and IgM binding to the dermal side only. We diagnosed this patient as nonscarring inflammatory EBA. Both patients were treated with prednisolone, colchicine, and dapsone resulting in clinical improvement, but their skin lesions recurred several months after discontinuing medication.

BACKGROUND: Many autopsy studies have shown that the extent of extracranial carotid and coronary artherosclerosis is correlated and B-mode ultrasonographic intima-media thickness(IMT) and histologic IMT have been good correlation. In recent years. as it has been reported that IMT of carotid artery had something to do with risk factors of atherosclerosis and occurrence of coronary artery disease, in this study, we tried to investigate if the grade of atherosclerosis in B-mode ultrasonography of carotid artery could predict coronary artery disease and have something to do with the severity of coronary artery disease. METHODS: We classified the patients who were examined coronary angiography into control group without significant(>50%) stenosis(11 patients) and coronary artery disease(CAD) group(45 patients) according to the existence of significant stenosis, and we subdivided CAD group into single vessel disease(SVD) group(25 patients) and multivessel disease(MVD) group(20 patients). Practicing B-mode ultrasonography of common carotid artery(CCA), carotid artery bifurcation(BIF) and internal carotid artery(ICA), we measured IMT and IMT/L(lumen diameter) of each segment. Adding all values of each segment, we got mean aggregated IMT and mean aggregated IMT/L. RESULTS: 1) As IMT of left BIF in both six segments, control group was 0.55+/-0.16mm, SVD group was 0.71+/-0.36mm and MVD group was 1.02+/-0.61mm. So compared with control group and SVD, MVD group were significantly thick. As IMT/L, control group was 0.07+/-0.02, SVD group 0.08+/-0.05 and MVD group was 0.13+/-0.08. So compared with control group and SVD, MVD group was ignificantly high. 2)IMT of BIF in three segments, control group was 0.59+/-0.16mm, CAD group was 0.82+/-0.47mm and MVD group was 0.90+/-0.54mm. So compared with control group and CAD, MVD group were significantly thick. Also as IMT/L of BIF, compared with control group(0.07+/-0.02) and CAD(0.10+/-0.06), MVD(0.11+/-0.07) group was high.= 3) As mean aggregated IMT, control group was 0.57+/-0.34mm, CAD group was 0.69+/-0.45mm, SVD group was 0.63+/-0.12mm and MVD group was 0.74+/-0.21mm. So CAD group was thicker than control group and MVD group was thicker than SVD group. As mean aggregated IMT/L, control group was 0.07+/-0.03, CAD group was 0.10+/-0.05, SVD group was 0.09+/-0.01 and MVD group was 0.11+/-0.03. So CAD group was higher than control group and MVD group was higher than SVD group. CONCLUSION: These data support use of the mean aggregated B-mode ultrasonographic IMT and IMT/L in carotid bifurcation for correlation with the status of coronary atherosclerosis.

Microsurgical clipping is considered the treatment of choice for ruptured intracranial aneurysms. However, ruptured posterior circulation aneurysms remain technically difficult to expose or clip and outcomes in these cases are poorer than those seen in cases of anterior circulation aneurysms. Therefore, endovascular treatment becomes another treatment option in cases of ruptured posterior circulation aneurysms. But, the vertebral artery may not be selected due to luminal narrowing, which are atherosclerotic stenosis clinically, congenital anomalies, or acquired kinking, and structural problem of angle between aorta, subclavian artery and vertebral artery. In these cases, other approaches can be used through, for example, subclavian, axillary, or brachial artery approach. But sometimes such prcedures may be also inappropriate. One other approach is direct percutaneous vertebral artery approach. Though this one also doesn't overcome many clinical and anatomical problems. The authors present two cases of ruptured basilar tip aneurysms which was treated with endovascular Guglielmi detachable coil embolization with open surgery and catheterization, because the one had anatomical problem, and the other had structural problem.

BACKGROUND: SSTR2 and SSTR5 are most frequently observed in GH-secreting pituitary tumors, and SSTR5 is believed to be more specific to mammosomatotroph lineage. Octreotide binds with high affinity to those two types. There is no report that investigates the quantitative comparison of the two subtype gene expressions, and the correlation between their gene expressions and GH response to octreotide in GH-secreting pituitary adenomas. METHOD: GH response to octreotide was examined in 8 acromegalic patients before transsphenoidal adenomectomy. Genomic DNA and RNA were prepared from fresh frozen tumor tissues. PCR was performed to amplify and sequence the region between codon 184 and 251 that includes exons 8 and 9 of the Gas gene. mRNAs of SSTR2 and SSTRS were quantitated by the comparative RT-PCR and in vitro transcription. RESULTS: The in vitro transcripts of SSTR2 and SSTR5 cDNA were detected in all tumors. The amount of SSTR transcripts was considerably variable between the tumors. The amount of SSTR5 transcript was significantly smaller than that of SSTR2 transcript (0.07+-0.02 vs. 0.87+-0.10), and they did not show any correlation . There was no signicant difference in sex, age, tumor size and grade, basal GH levels, and the GH responses to octreotide between the group with high and low SSTR gene expression. No significant correlation was found between the GH response to octreotide and the amount of SSTR2 transcript, wherease the amount of SSTR5 transcripts showed a tendency of negative correlation with the octreotide response. Tumors with gsp oncogene showed significantly higher response to octreotide than those without the oncogene. The amount of SSTRS transcript in gsp-positive tumors was significantly smaller than in gsp-negative tumors (0.03+-0.01 vs. 0.12+-0.03). CONCLUSION: These results suggest that SSTRS gene expression is lower than that of SSTR2 in GH-secreting adenomas. It is probably attributed to the binding of somatostatin to SSTR5 which has a higher affinity to the hypothalamic somatostatin, Tumors with gsp-oncogene is likely to express a higher density of SSTR5 than those without the oncogene.
