Among the various types of hepatic ductular atresias, there is a group of patients with a definable syndrome of malformations: typical physiognomy, malformation of pulmonary arteries, mental retardation and disturbed growth of body and genitals. This syndrome has been defined only in the last two years by Watson et al. (1973) and Allagille et al. (1975). A detailed description of a boy with this combination of malformations is given. Additionally he has aplasia of the right kidney. A second patient out of 4, which we found in our cardiologic department, has hypoblasia of one kidney, too. The prognosis of the liver disease in these patients seems to be better than in other children with biliary atresia.

Fourteen patients with "noncorrectable" biliary atresia are living without jaundice for more than 2 yr after hepatic portoenterostomy or its modification. Retardation of physical growth was observed in one of them, and mental retardation in another, both of which seemed irrelevant to biliary atresia. Serial tests for liver function after operation revealed early recovery of serum bilirubin, transminase, and turbidity, and delayed improvement of alkaline phosphatase. Postoperative needle biopsy of the liver disclosed that changes in hepatic parenchyma and ductular proliferation were rapidly improved after successful operation. Improvement of fibrosis of the liver was delayed, and it was not satisfactory in patients whose preoperative changes in the liver were severe or in whom ascending cholangitis had been a frequent complication. Histologic features of hepatic cirrhosis were observed in the liver in three cases, in two of which there had been frequent episodes of cholangitis. Only one of these showed clinical signs of portal hypertension. Functional and morphologic cure can be achieved in "noncorrectable" biliary atresia by hepatic portoenterostomy or its modifications, although varying degree of hepatic fibrosis may remain according to severity of preoperative changes of the liver and postoperative complication of ascending cholangitis.

Kabuki syndrome is a rare multiple congenital anomalies/mental retardation syndrome comprising a distinct facial appearance and fetal fingertip pads. We observed two patients with Kabuki syndrome and describe unusual life-threatening complications, including stenosis of the central airways (not previously reported), extrahepatic biliary atresia, and congenital diaphragmatic hernia.

Kabuki make-up syndrome (KMS, OMIM 147920) is an MCA/MR syndrome of unknown cause. It is characterized by a dysmorphic face, postnatal growth retardation, skeletal abnormalities, mental retardation, and unusual dermatoglyphic patterns. Approximately more than 350 cases have been reported from all over the world. Besides these five cardinal manifestations, joint laxity (74%), dental abnormalities (68%), and susceptibility to infections including recurrent otitis media (63%) were well recognized as other frequent features. A variety of visceral anomalies such as cardiovascular anomalies (42%), renal and/or urinary tract anomalies (28%), biliary atresia, diaphragmatic hernia, and anorectal anomaly were also reported. Some patients were said to have normal intelligence (16%) and normal heights, suggesting that they may have reproductive fitness to have their children. At least eight patients had lower lip pits with or without cleft palate, known as a feature of van der Woude syndrome. There have been 13 chromosomal abnormalities associated with KMS. However, no common abnormalities or breakpoints that possibly contribute to positional cloning of the putative KMS gene(s) are known. Although clinical manifestations of KMS are well established, its natural history, useful for genetic counseling, remains to be studied.

Kabuki (Niikawa-Kuroki) syndrome (KS) is characterized by a distinctive face, mental retardation, growth deficiency, skeletal anomalies, dermatoglyphic abnormalities, palatal anomalies, congenital heart defects, and urogenital malformations. Congenital hepatic abnormalities have been sporadically described in patients with KS from the literature, consisting of extrahepatic biliary atresia, neonatal sclerosing cholangitis, and severe neonatal jaundice. We report here on an additional patient with a congenital abnormality of the liver consisting of hepatic fibrosis. To our knowledge, idiopathic congenital hepatic fibrosis has not been reported in KS. Thus, our observation expands the spectrum of liver malformations found in KS with the inclusion of hepatic fibrosis and supports the evidence that hepatic abnormalities may not be uncommon in KS. Clinician should be advised to search for the specific facial anomalies of KS in patients with syndromic congenital hepatic diseases, and KS should be added to the list of previously recognized multiple congenital anomaly syndromes with hepatic involvement. Due to the frequent association with congenital heart malformations, KS should be considered in the evaluation of patients with neonatal liver disease and cardiac malformation. Due to the expression patterns of Notch genes, involvement of the Notch signaling pathway in the development of heart and liver anomalies in KS should be considered.

Biliary atresia (BA) is a rare disease, characterized by progressive and obliterative cholangiopathy, and is one of the major causes of secondary vitamin K deficiency in infancy. We describe 15 infants (10 female, 5 male) with BA, presenting with intracranial hemorrhage (ICH), including 10 subdural hemorrhages, 4 subarachnoid hemorrhages, 2 intraventricular hemorrhages, and 1 intraparenchymal hemorrhage. The age at onset of ICH ranged from 26 to 79 (mean 54.2) days. Eight patients underwent successful surgical evacuation of ICH, following administration of vitamin K. All 15 patients underwent Kasai portoenterostomy for BA 8-30 days after onset. During a mean follow-up period of 86.8 (range 2-352) months, 4 patients died of liver failure despite lack of neurological sequelae. Two patients underwent living-related donor and 1 patient living-unrelated donor liver transplantation. Only 2 patients suffered neurological signs and symptoms, including mental retardation and epilepsy, whereas 3 were noted to have temporary hemiparesis which recovered completely during the follow-up period. The possibility of BA should be considered in the treatment of ICH due to vitamin K deficiency, since it is reported to be one of the major causes of secondary vitamin K deficiency. Urgent surgical intervention for ICH can be performed successfully following sufficient administration of vitamin K or fresh frozen human plasma. Moreover, early performance of Kasai portoenterostomy is possible even for patients who have undergone craniotomy.
