Papillary carcinoma of the thyroid is a well differentiated neoplasm and usually has a good prognosis. However, a subset of morphologically distinct papillary carcinoma has bad prognoses. The tall cell variant of papillary carcinoma (TCPC), characterized by tall columnar cells with a height at least twice the width, is the one of these. In order to differentiate TCPC from usual papillary carcinoma (UPC) in terms of prognosis, we performed immunohistochemical studies for the expression of p53, bcl-2 and Leu-M1 proteins in 25 cases of TCPC, 26 cases of UPC and 14 cases of poorly differentiated, solid type papillary carcinoma (SPC) with an analysis of clinical parameters. The nuclear expression of p53 was noted in one case each of UPC and TCPC. The cytoplasmic p53 expression of TCPC, UPC, and SPC was observed in 17/25 cases (68%), 14/26 cases (54%), 3/14 cases (21%), respectively. bcl-2 expression was 19/25 cases (76%), 18/26 cases (69%), 5/14 cases (36%), and that of Leu-M1 was 21/25 cases (84%), 18/26 cases (69%), 4/14 cases(29%), respectively. There were no statistical significance in the expression of those immunoproteins among these three groups (p>0.05). The p53 protein was consistently expressed in the cytoplasm rather than nucleus in this study and was very well correlated to bcl-2 positivity (p<0.01). There were no statistical significance in any clinical parameters examined among these three groups (p>0.05). In conclusion, TCPC can not be separated from UPC as a distinct entity in this study and the cytoplasmic expression of p53 protein provides another mechanism of p53 inactivation in tumorigenesis of the thyroid papillary carcinoma, possibly by bcl-2 related mechanism.

PURPOSE: Vesicoureteral reflux (VUR) is the major cause of urinary tract infection (UTI) in children. Prolonged untreated UTI associated with VUR may result in serious complications, such as renal scarring, renal atropy, and decreased renal function. Therefore, follow up must be continued until UTI is cured completely, to prevent of serious complication. The authors conducted this study to evaluate results of the follow-up of UTI associated with VUR. METHODS: During the period from March 1991 to July 1996, we had 47 children with urinary tract infection associated with vesicoureteral reflux who were admitted to the Department of Pediatrics and Urology, Presbyterian Medical Center. The patients were managed medically or surgically. RESULTS: 1) There were no differences in sex distribution in the 47 cases with VUR. The intensity of 67 refluxing ureters, classified by the International Reflux Study Committee, grade I, 10 cases; grade II, 11 cases; grade III, 20 cases; grade IV, 17 cases; grade V, 9 cases. 2) The most common causative agent in UTI was E. coli. Fourty-six cases underwent ultrasonography and 24 showed abnormal findings. Fourty-four cases underwent a 99mTc-DMSA renal scan, and 25 showed abnormal findings. The incidence of renal scarring showed a direct correlation with the severity of VUR. 3) The incidence of urinary tract infection during follow-up did not differ between the groups medical management versus surgical management. 4) Fourty-four refluxing ureters were treated primary medically and 38 of them were followed up. Twenty-five of the 38 ureters were disappeared or improved, and 9 persisted. The rest showed aggravation of reflux. Twenty-five of the 32 refluxing ureters showed disappearance or improvement of reflux before 5 years of age, The spontaneous cure rate of vesicoureral reflux seemed to be higher in the cases with a milder grade of reflux. 5) Although refluxing ureter disappeared completely on VCUG, we found that follow-up is continued until the disappearance of reflux is confirmed on two serial VCUG. 6) Thirty-three refluxing ureters were treated surgically and one of them was stationary on follow-up VCUG, while the others were cleared. CONCLUSIONS: As a result of follow-up the 47 patients with VUR, the incidence of urinary tract infection did not differ between the groups medical versus surgical management. Rates of disappearance of VUR in medical and surgical management were 66%, 97%, respectively. The spontaneous cure rate of VUR seemed to be higher in the cases with a milder grade of reflux and before 5 years of age. We found that follow-up is continued until the disappearance of reflux is confirmed on two serial VCUG.

Crossed renal ectopia is a congenital malformation in which both kidneys lie on the same side of the spine, usually side by side longitudinally. More often on the right side. Fusion of the two renal units is eight times more common than nonfusion. Although crossed renal ectopia is uncommon, this unusual entity must be considered in an infant when cystic mass in the abdomen or pelvis paticularly if no kidney can be found on the opposite side. In many cases of crossed fused ectopia with multicystic dysplastic kidney(MCDK), the diagnosis can be strongly suspected from the sonogram, and no other studies may be necessary. However, both intravenous urography and isotope renography is useful to assess the function of the crossed kidney. Crossed renal ectopia and MCDKs are associated with a greater incidence of ureteropelvic junction obstruction and reflux. So, screening voiding cystourethrography should be performed. Very few studies of MCDK in the setting of crossed fused ectopia have been reported. We have experienced a 3-year-old boy with crossed fused renal ectopia with multicystic dysplasia.

Neurofibromatosis type 1 (NF1; also known as von Recklinghausen's neurofibromatosis) is inherited in an autosomal dominant fashion, although it can also arise due to spontaneous mutation. Gastrointestinal involvement of NF1 is seen in 10% to 25% and causes symptoms in fewer than 5%. Histologically, the gastro intestinal (GI) manifestation of NF1 occurs in three forms: hyperplasia of the gut neural tissue, stromal tumors, and duodenal or periampullary endocrine tumors. A 31-year-old female, diagnosed with NF1, presented with poor oral intake and vomiting for 10 days prior to admission. Preoperative gastrofiberscopic finding was gastric outlet obstructing polypoid duodenal bulb lesion. The patient underwent hemigastrectomy with antecolic gastrojejunostomy due to gastric outlet obstruction. The final pathologic report was submucosal neurofibromatous proliferation with Brunner's gland hyperplasia located at the duodenal bulb in the NF1 patient. We report this case with a review of literatures.

Journal of the Korean Pediatric Society 1996;39(1):88-96
PURPOSE: To investigate the risk factors of recurrence after their first febrile convulsions. And to evaluate effect of anticonvulsant therapy with recurrent febrile convulsion infants and children. METHODS: We have studied the relationship of their clinical pictures and factors related to the risk of recurrence of 178 patients with primary or recurrent febrile convulsion, who were admitted to department of pediatrics, or visited to emergency room, chonju presbyterian medical center from january 1983 to december 1992. The 178 patients were followed up and consisted of the 97 patients with primary febrile convulsion and the others 81 patients with recurrent febrile convulsions. RESULTS: 1) In sex distribution, the boys(59%) outnumbered the girls(41%) and the ratio was 1.4:1. 2) 95% of overall patients were occurred febrile convulsion under 5 year-old and recurrent rate was 45.5%. In recurrent cases, the first episode under the 12 months was 50.6%(p<0.005). 3) There were family history of febrile convulsion in 28.4% of recurrent cases, compared to 10.9% of primary cases(p<0.001). 4) There was no significant difference with duration and type of convulsion in both groups. 5) Small proportion of 27 children were prescribed anticonvulsants (phenobarbital), but it's not reduced the recurrence and epilepsy significantly. CONCLUSIONS: The risk factor of recurrent febrile convulsion were the first episode under 12 month and familial history of febrile convulsion.

Journal of Korean Medical Science 2023;38(15):e119-
Background:
To investigate the actual rate and quality of cardiac rehabilitation (CR) participation in South Korea and its short-term impact on clinical outcomes after acute coronary syndrome (ACS).
Methods:
Data, including confirmed ACS diagnosis, socio-demographics, comorbidities, clinical outcomes, and CR claim codes, were collected from the Korean National Health Insurance Service claims database and compared between the CR and non-CR groups.
Results:
Overall, 102,544 patients were included in the study, of which only 5.8% attended CR. Regarding testing, 83.6% of CR patients performed the cardiopulmonary exercise test, but follow-up testing was infrequently performed; in addition, 53.1% of them participated in an electrocardiogram monitoring exercise, but over half participated in only one session.After 1:1 propensity score matching, post-ACS cardiovascular events were significantly lower in the CR group than in the non-CR group. The cumulative 3-year hazard ratio for all-cause death was 0.612 (95% confidence interval [CI], 0.495–0.756), recurrent ACS was 0.92 (95% CI, 0.853–0.993), CR readmission was 0.817 (95% CI, 0.768–0.868), and major adverse cardiovascular events (MACE) was 0.827 (95% CI, 0.781–0.874) in the CR group. CR was associated with a significant dose-response effect on MACE, with a reduction in incidence from 0.854 to 0.711.
Conclusion
The actual rate of CR participation in South Korea remains low, and participation quality was not outstanding despite National Health Insurance coverage.Nevertheless, the impact of CR on cardiovascular outcomes after ACS was significantly superior. Efforts to increase CR participation should be increased by establishing new CR facilities and strategies to resolve associated barriers.

This study was designed to determine the effectiveness of transrectal ultrasonography compared with chain cystourethrography in stress urinary incontinence. The advantages of transrectal ultrasonography are that it is a simple. comfortable, noninvasive and quick out patient procedure. The diagnostic criteria of stress urinary incontinence are more than 146.6` in posterior urethrovesical angle, more than 1.02cm in bladder neck descent and more than 0.14cm in bladder neck opening. In conclusion, transrectal ultrasonography is a highly sensitive and specific method for the diagnosis of stress urinary incontinence.

A case report described a 72-year-old man with a history of a deceased-donor liver transplantation (due to hepatitis B-associated end-stage liver cirrhosis) performed in 1994. The patient was diagnosed with renal cell carcinoma and pulmonary metastasis in 1997 and was successfully treated with radiofrequency ablation and thoracoscopic superior segmentectomy. There was no evidence of newly diagnosed metastatic lesions or recurrence until the 19th post-operative month. Gastric cancer was identified by endoscopy during a routine follow-up examination; the pre-pyloric antral lesion measured 1.5 cm in size and was histologically well-differentiated and confined to the submucosal layers on endoscopic ultrasound. Laparoscopic gastrectomy and lymph node dissection (D1 + beta) was successfully performed in March 2009, and the patient was discharged on the 5th post-operative day without complications. This suggests that laparoscopic surgery is one of the feasible methods for resection of gastric cancer in liver transplant patients.
