  • The etiology of several motility disorders, including persistent megacolon after definitive surgery for Hirschsprung's disease, meconium ileus which is not associated with cystic fibrosis and idiopathic megacolon, is still unclear. Interstitial cells of Cajal (ICC) are thought to modulate gut motility as gastrointestinal pace maker cells. The aim of this study was to evaluate the role of ICC in the bowel walls of the patients (n=15) who had variable motility disorders. The ICC were identified by immunohistochemical staining using an anti-C-Kit antibody and the results were compared with control specimens (n=2). The control group (G1) showed evenly distributed ICC in their bowel walls. The second group (G2, n=5) who had normal bowel movements after Duhamel procedures and the third group (G3, n=4) who had persistent megacolon after Duhamel procedures showed absent or scarcely distributed ICC in their aganglionic bowels. The ICC were immunohistochemical staining using an anti-C-Kit antibody and the results were compared with control specimens (n=2). The control group (G1) showed evenly distributed ICC in their bowel walls. The second group (G2, n=5) who had normal bowel movements after Duhamel procedures and the third group (G3, n=4) who had persistent megacolon after Duhamel procedures showed absent or scarcely distributed ICC in their aganglionic bowels. Whereas ICC were evenly distributed in the ganglionic bowels of G2, they were not seen or scarecely distributed in the ganglionic bowels of G3. Two patients (G4) who suffered from idiopathic megacolon showed absence or decrease of ICC in spite of presence of ganglion cells in their colons. Four neonates (G5) who underwent ileostomy because of meconium obstruction showed absent or markedly decreased ICC in the the colon at the time of ileostomy and the distribution of ICC was changed to a normal pattern at the time of ileostomy closure between 39-104 days of age and their bowel motility were restored after that. The results suggest that lack of ICC caused reduce motility in the ganglionic colons and it may be responsible for the development of various motility disorders. Delayed maturity of ICC may also playa role in the meconium obstruction of neinates.

  • 독성거대결장은 염증성 장질환, 감염성 대장염 등에 의해 발생하는 치명적인 합병증이다. 중증도에 따라 장절제부터 사망까지 예후가 나빠 조기 진단과 적절한 치료가 매우 중요한 질환이다. 하지만, 소아에서 그 유병률은 매우 낮으며 염증성 장질환과 같은 기저질환이 없이 발생할 경우 조기진단이 늦어질 수 있다. 기저질환이 없는 12세 남자가 하복부 통증과 발열, 그리고 혈변을 주소로 병원을 방문했다. 항생제 치료에도 불구하고 환자의 증상은 악화되었다. 3병일째 복부 컴퓨터단층촬영에서 횡행결장의 심각한 팽창이 관찰되었고 이를 통해 독성거대결장으로 진단할 수 있었다. 광범위항생제와 함께 정맥 스테로이드 치료를 시행하였으며, 환자의 증상은 호전되었다. 이후 대변 배양 검사에서 Salmonella enteritidis group D가 배양되었으며, 직장 내시경 검사를 통해 염증성 장질환을 배제할 수 있었다. 저자는 독성거대결장을 적절한 영상 검사를 통해 조기 진단하였고, 내과적으로 성공적인 치료를 하여 이에 대한 경험을 공유하고자 한다.

  • 9개월령 페르시안종 수컷 고양이(체중 3.2 kg)가 변비를 주증으로 내원하였다. 진단검사상 심한 변비와 거대 결장증이 확인되었다. 관장을 비롯한 즉각적인 응급처치를 실시한 후 신체검사를 실시하였고, 검사결과 음경구 0.5 cm 복측에서 비정상적인 요도구를 확인하였다. 이 요도구를 통해 3.5 fr tomcat catheter를 방광내부를 쉽게 삽입할 수 있었다. 영상진단과 신체검사를 통해 본 증례는 요도밑 열림증으로 진단되었다. 본 고양이는 중성화 수술과 함께 변비에 대한 내과적 처치가 실시되었다. 본 증례는 우리나라에서 처음으로 보고되는 만성 변비를 동반한 고양이의 요도밑 열림증이다.

  • KBG syndrome is an autosomal dominant syndrome presenting with macrodontia, distinctive facial features, skeletal anomalies, and neurological problems caused by mutations in the ankyrin repeat domain 11 (ANKRD11) gene. The diagnosis of KBG is difficult in very young infants as the characteristic macrodontia and typical facial features are not obvious. The youngest patient diagnosed to date was almost one year of age. We here describe a 2-month-old Korean boy with distinctive craniofacial features but without any evidence of macrodontia due to his very early age. He also had a congenital megacolon without ganglion cells in the rectum. A de novo deletion of exons 5-9 of the ANKRD11 gene was identified in this patient by exome sequencing and real-time genomic polymerase chain reaction. As ANKRD11 is involved in the development of myenteric plexus, a bowel movement disorder including a congenital megacolon is not surprising in a patient with KBG syndrome and has possibly been overlooked in past cases.

  • Congenital central hypoventilation syndrome (CCHS) is a disorder of the autonomic nervous system characterized by a decreased response to hypercarbia. CCHS is frequently associated with congenital megacolon; the combination is called Haddad syndrome. CCHS is associated with dysfunction in respiratory features of the autonomic nervous system and with other disorders, including facial deformities, cardiovascular symptoms, and tumors. Patients with CCHS frequently have a mutation in the homeobox protein 2b (PHOX2B) gene. Most mutations involve heterozygous expansion of alanine repeats (GCN). Interestingly, a higher polyalanine repeat number is associated with a more severe clinical phenotype. To clarify the role of PHOX2B in disease pathogenesis, we introduce and review the clinical and molecular features of CCHS and Haddad syndrome.

  • Congenital central hypoventilation syndrome은 혈중 이산화탄소 증가와 저산소에 대한 자율 신경계와 호흡 조절 기능의 선천성 결함으로 호흡의 저환기가 주로 수면시에 발생하는 질환이다. 이는 신경 이주장애 질환(neurocristopathy)에 속한다고 알려져 있으며 선천성 거대결장 등의 질환과 잘 동반된다. 아직까지 확실한 완치법은 없는 상태이고 환아들은 평생을 환기 보조에 의존하여 생존해야 하며 적절한 환기 보조를 통해서 생존 기간을 연장할 수 있다. 저자들은 출생시부터 반복되는 수면시의 무호흡과 청색증이 있는 환아에서 congenital central hypoventilation 및 선천성 거대 결장이 동반된 1례를 경험하였기에 보고하는 바이다.

  • Sotos syndrome (SS, OMIM 117550) is characterized by prenatal and postnatal overgrowth with multiple congenital anomalies. However, there have been few cases of growth retardation caused by renal failure from infancy. We report a case of dysplasia of the bilateral kidneys with renal failure and poor postnatal growth. A 2-month-old boy visited the emergency room owing to poor oral intake and abdominal distension. He was born at the gestational age of 38 weeks with a birth weight of 4,180 g. After birth, he had feeding difficulty and abdominal distension. Upon physical examination, his height and weight were in less than the 3rd percentile, while his head circumference was in the 50th percentile on the growth curve. He also showed a broad and protruding forehead and high hairline. Blood laboratory tests showed severe azotemia; emergent hemodialysis was needed. Abdominal ultrasonography revealed bilateral renal dysplasia with multiple cysts and diffuse bladder wall thickening. A posterior urethral valve was suggested based on vesicoureterography and abdominal magnetic resonance findings. Results of a colon study to rule out congenital megacolon did not reveal any specific findings. The conventional karyotype of the patient was 46, XY. Array comparative genomic hybridization study revealed a chromosome 5q35 microdeletion including the NSD1 gene, based on which SS was diagnosed. We describe a case of SS presenting with end stage renal disease due to posterior urethral valve. The typical somatic overgrowth of SS in the postnatal period was not observed due to chronic renal failure that started in the neonatal period.
