From January 1993 to December 1995, 47 patients with rectal carcinomas underwent a rectal anastomosis using the double stapling technique at the Surgical Department of Kwang-ju Christian Hospital. The major advantages of the double stapling technique for lower rectal cancer over the single stapling technique or a hand-sewn operation are as follows:1) Insertion of a purse-string suture is eliminated, and application of a linear stapler to close the distal rectum may be performed with greater ease. 2) In addition, fecal contamination and spillage of tumor cells from the rectal segment are minimized. 3) Differences in the sizes of the colons and rectums are not a concern in constructing the anastomosis. 4) The operating time is shorter. The following results were obtained by a comparison with 24 patients with rectal carcinoma who had undergone a rectal anastomosis using the double stapling technique from January 1989 to December 1992 which was reported in a previous study:1) Anastomotic stenosis was decreased from 8.3% to 4.2% because of reduced ischemia due to the double row of staples and the reduced injury due to compression of tissue between the anvil and the cartridge with experience. In addition, it resulted from reduced tension of the anastomosis due to sufficients mobilization of the proximal colon and from selection of large cartridge (33 mm). 2) Anastomotic leakage, even though the same location as the tumor and in the advanced age group, was decreased from 4.2% to 0% because the blood circulation was maintained and unnecessary tension was reduced with experience. In addition, it resulted from reinforced suture of the anastomotic site which was performed after anastomosis. 3) Systemic recurrence was the same result as that of the previous study(4.2/4.3%). 4) Local recurrence, even though at the same distal distance from the margin of the cancer, was increased from 0% to 2.1% because of advancing the pathologic stage (B2, C1>B1, B2) and increasing the poorly differentiated pathologic type.

18 humerus fractures in multiple injured patients were treated by closed intramedullary Ender nailing from June 1987 to June 1988. Follow-up over 3 months were obtained for 11 patients(11 fractures) and results were as follows : 1. Male was 10 in 11 cases and age was widely distributed to that of active life. 2. Trauma was the main cause of injury. 3. Ender nails were inserted through retrograde of entry in 6 cases and antegrade in 5 cases. 4. Coaptation splint was removed at postop. 3rd day and active joint exercise was started. 5. The average time of initial callus formation was post injury 19.2 days and that of solid periosteal callus bridge formation was post injury 7.5 weeks. 6. Early joint exercise, early mobilization of patient, ease of general care, small amount of blood loss, etc. were thought to be the adventages of closed Ender intramedullary nailing for humerus fractures especially in multiple injured patients.

BACKGROUND: Bupivacaine is a amide type local anesthetic agent, widely used for its excellent quality of analgesia and long duration of action. But unintended intravenous injection causes severe complication such as convulsion and cardiovascular collapse, which is known for its difficulty in resuscitation. With all the study, the exact mechanism is still unclear and there are much debate on the method of resuscitation. METHOD: We studied the effect of clonidine pretreatment on bupivacaine-induced cardiac toxicity and resuscitation in anesthetized dog. Twelve dogs were divided into two groups. : saline pretreatment group (control, N=6) and clonidine pretreatment group (clonidine group, N=6). The dogs were anesthetized with N2O-O2-enflurane and vecuronium. Thoracotomy was done in 4th or 5th intercostal space for open cardiac massage. After confirming stability of vital signs, we administered clonidine (10 mcg/kg) or saline, and then administered bupivacaine with the rate of 2 mg/kg/min. When the electeocardiogram showed asystole, 20 mcg/kg of epinephrine was administered via central venous line and open cardiac massage with the rate of 120 beat/min. was performed. We observed electrocardiogram (lead II), arterial blood pressure, heart rate, dose of infused bupivacaine to be required for QRS widening and arrest, required time and administered dose of epinephrine for resuscitation. RESULTS: Clonidine group showed significant decrease of heart rate after pretreatment (p<0.05). There was no significant difference in required dose for QRS widening between two groups. The dose administered for inducing arrest was less in clonidine group than control group (p<0.05). The time required for resuscitation was shorter in clonidine group than control group (p<0.05). The total dose of epinephrine required for resuscitation was less in clonidine group than control group (p<0.05). The blood concentration of catecholamine did not showed significant difference during the whole course of experiment. CONCLUSIONS: Above results demonstrated that clonidine, a central nervous system-mediated sympatholytic agent, facilitated cardiac arrest when bupivacaine was infused intravenously and cardiac rescucitation.

We aimed to investigate epidemiology and host- and pathogen-related factors associated with clinical severity of acute gastroenteritis (AGE) in children after rotavirus vaccination introduction. Factors assessed included age, co-infection with more than 2 viruses, and virus-toxigenic Clostridium difficile co-detection. Fecal samples and clinical information, including modified Vesikari scores, were collected from hospitalized children with AGE. The presence of enteric viruses and bacteria, including toxigenic C. difficile, was detected by polymerase chain reaction (PCR). Among the 415 children included, virus was detected in stool of 282 (68.0%) children. Co-infection with more than 2 viruses and toxigenic C. difficile were found in 24 (8.5%) and 26 (9.2%) children with viral AGE, respectively. Norovirus (n = 130) infection, including norovirus-associated co-infection, was the most frequent infection, especially in children aged < 24 months (P < 0.001). In the severity-related analysis, age < 24 months was associated with greater diarrheal severity (P < 0.001) and modified Vesikari score (P = 0.001), after adjustment for other severity-related factors including rotavirus status. Although the age at infection with rotavirus was higher than that for other viruses (P = 0.001), rotavirus detection was the most significant risk factor for all severity parameters, including modified Vesikari score (P < 0.001). Viral co-infection and toxigenic C. difficile co-detection were not associated with any severity-related parameter. This information will be helpful in the management of childhood AGE in this era of rotavirus vaccination and availability of molecular diagnostic tests, which often lead to the simultaneous detection of multiple pathogens.

Acute acalculous cholecystitis (AAC) is an inflammation of the gallbladder in the absence of demonstrated stones. AAC is frequently associated with severe systemic inflammation. However, the exact etiology and pathogenesis of AAC still remain unclear. Acute infection with Epstein Barr virus (EBV) in childhood is usually aymptomatic, whereas it often presents as typical infectious mononucleosis symptoms such as fever, cervical lymphadenopathy, and hepatosplenomegaly. AAC may occur during the course of acute EBV infection, which is rarely encountered in the pediatric population. AAC complicating the course of a primary EBV infection is usually associated with a favorable outcome. Most of the patients recover without any surgical treatment. Therefore, the detection of EBV in AAC would be important for prediction of better prognosis. We describe the case of a 10-year-old child who presented with AAC during the course of primary EBV infection, the first in Korea, and review the relevant literature.

PURPOSE: Crigler-Najjar syndrome type II (CN-2) is characterized by moderate non-hemolytic unconjugated hyperbilirubinemia as a result of severe deficiency of bilirubin uridine diphosphate-glucuronosyltransferase (UGT1A1). The study investigated the mutation spectrum of UGT1A1 gene in Korean children with CN-2. METHODS: Five Korean CN-2 patients from five unrelated families and 50 healthy controls were enrolled. All five exons and flanking introns of the UGT1A1 gene were amplified by polymerase chain reaction (PCR) and the PCR products were directly sequenced. RESULTS: All children initially presented with neonatal jaundice and had persistent indirect hyperbilirubinemia. Homozygous p.Y486D was identified in all five patients. Three patients had an associated homozygous p.G71R and two a heterozygous p.G71R. The allele frequency of p.Y486D and p.G71R in healthy controls was 0 and 0.16, respectively. No significant difference in mean serum bilirubin levels was found between homozygous carriers of p.G71R and heterozygous carriers. CONCLUSION: The combination of homozygous p.Y486D and homozygous or heterozygous p.G71R is identified. The p.Y486D and p.G71R can be screened for the mutation analysis of UGT1A1 in Korean CN-2 patients.

PURPOSE: Diencephalic syndrome is an uncommon cause of failure to thrive in early childhood that is associated with central nervous system neoplasms in the hypothalamic-optic chiasmatic region. It is characterized by complex signs and symptoms related to hypothalamic dysfunction; such nonspecific clinical features may delay diagnosis of the brain tumor. In this study, we analyzed a series of cases in order to define characteristic features of diencephalic syndrome. METHODS: We performed a retrospective study of 8 patients with diencephalic syndrome (age, 5-38 months). All cases had presented to Seoul National University Children's Hospital between 1995 and 2013, with the chief complaint of poor weight gain. RESULTS: Diencephalic syndrome with central nervous system (CNS) neoplasm was identified in 8 patients. The mean age at which symptoms were noted was 18+/-10.5 months, and diagnosis after symptom onset was made at the mean age of 11+/-9.7 months. The mean z score was -3.15+/-1.14 for weight, -0.12+/-1.05 for height, 1.01+/-1.58 for head circumference, and -1.76+/-1.97 for weight-for-height. Clinical features included failure to thrive (n=8), hydrocephalus (n=5), recurrent vomiting (n=5), strabismus (n=2), developmental delay (n=2), hyperactivity (n=1), nystagmus (n=1), and diarrhea (n=1). On follow-up evaluation, 3 patients showed improvement and remained in stable remission, 2 patients were still receiving chemotherapy, and 3 patients were discharged for palliative care. CONCLUSION: Diencephalic syndrome is a rare cause of failure to thrive, and diagnosis is frequently delayed. Thus, it is important to consider the possibility of a CNS neoplasm as a cause of failure to thrive and to ensure early diagnosis.
