The sacrococcygeal region is the frequent site for meningocele, congenital dermal sinus and pilonidal cyst. From May 1995 to July 1998, we have treated 8 neonatal patients with an abscess in the sacrococcygeal area. The mean age at onset was 8.3 days with a range from 6 to 11 days. The sex ratio was 5:3 with male preponderance. Mild fever was the only systemic symptom. Ultrasonogram revealed a slightly hypo echoic lesion in the subcutaneous tissue which became more hypoechoic with time. Pus cultures showed $Staph.$ $aureus$ in 7 patients, two of them had mixed infection with $E.$ $coli$ and other 2 had methicillin-resistant $Staph.$ $aureus.$ The remaining one patient had a mixed infection with $Klebsiella$ and $Proteus.$ Histopathological examination revealed non-specific granuloma and fibrinoid necrotic debris. All patients were easily treated by incision, drainage and proper antibiotics.

We report a 12-month-old female infant who had a history of neonatal sepsis with liver micro-abscesses that resolved with intravenous antibiotics during neonatal period. During her neonatal admission period, no umbilical vein catheter was inserted. Also, she did not undergo any abdominal surgeries or had a postnatal history of necrotizing enterocolitis. However, the child developed upper gastrointestinal bleeding in form of hematemesis and melena secondary to esophageal varices at the age of 12 months with an extra-hepatic portal vein obstruction with cavernous transformation and portal hypertension subsequently. The child underwent a successful endoscopic injection sclerotherapy. She is now 20-month-old and has portal hypertension but otherwise asymptomatic. We are proposing the possibility of a delayed-onset portal hypertension as a complication of liver abscess and neonatal sepsis.

신생아의 뇌 농양은 극히 드문 경우로 특정 선행 요인을 가지고 있는 경우가 많다. 가장 흔한 원인 균주는 그람 음성 균주이며 치료법의 발달로 사망률은 감소하였지만 반신 마비, 경련, 발달 장애 등의 후유증이 남을 수 있다. 39일 된 남아가 하루 전부터 시작된 발열을 주소를 내원하였다. 환아는 조산, 저 체중 출산아로 신생아 중환자실에 입원했던 경력이 있었다. 신체 검진상 대천문이 팽창된 것 외에 다른 신경학적 증후는 보이지 않았다. 신경 촬영 검사상 양측 전두엽에 정중선이 오른쪽으로 치우쳐 있는 뇌 농양으로 의심되는 거대한 병변이 있었다. 뇌 농양이 매우 컸음에도 불구하고 수술장으로 이동하지 않고 환자의 침상에서 직접 단순 흡입 치료를 시행하였고 항생제 치료를 병행하였다. 원인균은 Enterobacter cloacae로 판명되었고 meropenem을 8주간 투여 하였다. 환아는 빠른 회복을 보이며 이후 어떤 신경학적 휴유증도 보이지 않았다. 저자들은 Enterobacter cloacae 감염에 의한 거대한 뇌 농양이 발견된 신생아를 단순 흡입과 항생제 만으로 치료 하였고 이후 좋은 경과를 보인 1례를 경험하였기에 보고하는 바이다.

신생아 간농양은 특별한 증상이 발현되지 않거나 비특이적인 증상 때문에 진단이 늦어지는 경우가 많다. 항생제의 사용에도 불구하고 염증 반응이 지속되며 복부증상이 함께 나타나는 경우, 주산기 산모의 심한 감염, 융모양막염 등의 선행인자가 있고, 제대혈관 도관과 관련된 패혈증이 있는 경우에는 간농양의 가능성을 고려해야 한다. 저자들은 생후 9일된 미숙아에서 제대정맥 도관과 함께 산모의 폐렴 및 심한 융모양막염이 선행요인이 되어, 단일성 간농양이 발생한 진단된 사례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

Congenital dermal sinus (CDS) is a type of occult spinal dysraphism characterized by a midline skin dimple. A 12-month-old girl presented with fever and ascending quadriparesis. She had a midline skin dimple in the upper sacral area that had been discovered in her neonatal period. Imaging studies revealed a holocord intramedullary abscess and CDS. Overlooking CDS or misdiagnosing it as benign sacrococcygeal dimple may lead to catastrophic infection and cause serious neurological deficits. Therefore, further imaging work-up or consultation with a pediatric neurosurgeon is recommended following discovery of any atypical-looking dimples in the midline.

Three swine farms which were suffering from slight economic loss due to suckling piglets' diarrhea, were selected to apply commercialized multivalent vaccine for sow use; $SUISENG^{(R)}$ (Hipra, Spain). Farms were pre-diagnosed with clinical symptoms and molecular detection of C. perfringens Type A and C and E. coli pili by PCR. Sows were vaccinated twice 2 ml of the vaccine at 6 and 3 weeks ante partum intramuscularly according to the manufacturer's instruction. All vaccinated sows did not show any adverse reaction or clinical signs; hypersensitivity, fever, granuloma or abscess on the injection site, appetite loss, and so on. Also, no reproductive disorder was appeared in vaccinated sows compared with non-vaccinated control sows. The results suggested that piglets born from vaccinated sows show significantly better performance in regard of the diarrhea index and mean daily weight gain compared with piglets from non-vaccinated sows. Therefore, the commercial vaccine for the prevention of neonatal diarrhea is found to be effective in reducing diarrhea in the first suckling period of piglets after birth.

Conventional treatment of Hirschsprung's disease consists of initial colostomy followed by pull-through operation. But, the treatment of Hirschsprung's disease has been changed along with the development of new surgical technique. Since 1995, endo-GIA has been available at our hospital and one stage Duhamel operation has been performed for neonatal Hirschsprung's disease. Between May 1995 and April 2006, 26 neonates have been treated with one stage pull-through operation by one pediatric surgeon at HanYang University Hospital. The sex ratio was 4.2:1 with male predominance. Clinical findings included abdominal distension (96.2 %), vomiting (50.0 %), delayed passage of meconium (46.2 %), constipation (23.1 %), and enterocolitis (15.4 %). Twenty two cases (84.6 %) were short-segment and 4 cases (15.4 %) were long-segment disease, of which 2 cases were total colon aganglionosis. One of the two patients with total colonic aganglionosis had double transition zones - distal ileum and hepatic flexure of the colon. The average age at operation was $14.56{\pm}8.77$ days and the average weight at operation was $3.26{\pm}0.66kg$. Primary Duhamel operations were performed in 25 patients and Soave-Boley operations was performed in one patient. The endo-GIA 35 (Ethicon, USA) was used from 1995 until 1997, and after that endo-GIA 60 (USSC, USA) was used. The average Duhamel operation time was $88.57{\pm}22.80$ minutes. Wound abscess (n = 2) and septum formation (n =1) occurred after Duhamel operation. Bowel function was normalized in 59 % within 3 months and in 95% within 1 year after operation. There was no mortality after one stage pull-through operation in neonate.

Pulmonary sequestration (PS) is a rare congenital malformation of the lower respiratory tract. The anomaly is characterized by absence of communication with the tracheobronchial tree and isolated blood supply from an anomalous systemic vessels. With the utilization of antenatal ultrasound, the diagnosis of asymptomatic neonatal PS has increased. Treatment options include observation, arterial embolization and surgical resection. The aim of the present study is to review the clinical course of PS and to share our experience with thoracoscopic resection. A total of 96 patients with PS were treated at Asan Children's Hospital between 1999 and 2010. The diagnosis of PS was established by CT in the cases managed by observation or embolization, and by tissue pathology in the surgical cases. Medical records and radiographic images were retrospectively reviewed. Thirty-nine patients were managed by embolization and 30 patients by surgery. The remaining 27 patients have been under observation without any procedures. Among 27 observation patients, 1 patient regressed completely and 10 patients were lost to follow up. Of the 39 embolizations patients, 2 had their lesion regress and sepsis was suspected after embolization. In 1 patient, the microcoil migrated to the iliac artery during the embolization procedure, and another patient developed renal abscess caused by renal artery embolization. Among 30 surgical cases, resection by thoracotomy was performed in 27 at the Department of Thoracic Surgery, and thoracoscopic resection in 3 at the Division of Pediatric Sugery. Only one wound complication ocurred. We conclud that surgical excision should be recommended for pulmonary sequestration, whether the sequestration is symptomatic or not because of the risk of infection, the low rate of natural regress, poor compliance, severe complications after embolization, and to exclude other pathology. In summary, thoracoscopic resection of the pulmonary sequestration is feasible, efficacious, safe and cosmetically superior even in neonatal period.
