ABSTRACT
Biliary atresia (BA) is classically described at the neonatal age. However, rare cases of BA in older infants have also been reported. We report four cases of late-onset BA in infants older than 4 weeks (3 males, 1 female), and describe the diagnostic and management difficulties. One of the cases had a late-onset (29 weeks) presentation with a successful surgical procedure. We highlight the importance of this unusual differential diagnosis in infants with cholestatic syndrome, who may benefit from Kasai surgery, regardless of age.

BACKGROUND: Posterior subcapsular cataract (PSC) has been reported in patients on corticosteroids therapy for various pathologies. Autoimmune hepatitis (AIH) is a progressive inflammatory hepatic disease for which corticosteroids are recommended but PSC has not yet been reported in AIH patients on corticosteroids therapy. METHODS: The AIH patients at our service underwent an ophthalmological assessment and their files were analyzed establish the dosage and duration of medication, the presence of visual complaints and the type of AIH, in order to correlate these with the ophthalmological findings. Patients were examined with a slit lamp following pupil dilation. RESULTS: 17 AIH patients evaluated, only one patient had PSC. CONCLUSION: Although the frequency of PSC was low (1/17) in AIH patients on costicosteroid therapy, these individuals should undergo occasional ophthalmological assessment for the presence of cataracts since their visual acuity and quality of life may be adversely affected.

Caroll's disease is characterized by congenital non-obstructive dilatation of the intrahepatic bile ducts of undefined etiology. It is a rare disease usually affecting the whole liver but it may affect a lobe or a segment (11). This study shows the evolution of 6 cases (2 boys and 4 giris) that were diagnosed with Caroli's disease at a referral service. Their ages ranged from 2 to 16 years--median age 10 years. One of the patients presented with cholangitis, while hepatomegaly was observed in 83% of the cases. Four of the patients presented biliary lithiasis and in one of these cholesterol crystals could be observed in the duodenal secretion. The diagnosis was confirmed in 4 cases by endoscopic retrograde cholangiopancreatography, in 1 by cholangioresonance and 1 by echography. Two of the patients also presented congenital hepatic fibrosis. The outpatient clinic follow-up indicated that all the patients evolved well with the exception of one patient who was selected as a candidate for liver transplantation.

ABSTRACT
BACKGROUND: Alpha-1-antitrypsin deficiency is a genetic disorder which is transmitted in a co-dominant, autosomal form. Alpha-1-antitrypsin deficiency affects mainly the lungs and the liver leading, in the latter case, to neonatal cholestasis, chronic hepatitis or cirrhosis. A precise diagnosis of Alpha-1-antitrypsin deficiency may be obtained by biochemical or molecular analysis. OBJECTIVE: The purpose of this study was to use DNA analysis to examine the presence of an alpha-1-antitrypsin deficiency in 12 children suspected of having this deficiency and who showed laboratory and clinical characteristics of the disease. PATIENTS AND METHODS: Twelve patients, aged 3 months to 19 years, who had serum alpha-1-antitrypsin levels lower than normal and/or had hepatic disease of undefined etiology were studied. The mutant alleles S and Z of the alpha-1-antitrypsin gene were investigated in the 12 children. Alpha-1-antitrypsin gene organization was analyzed by amplification of genome through the polymerase chain reaction and digestion with the restriction enzymes Xmnl (S allele) and Taq-1 (Z allele). RESULTS: Seven of the 12 patients had chronic liver disease of undefined etiology and the other five patients had low serum levels of alpha-1-antitrypsin as well as a diagnosis of neonatal cholestasis and/or chronic liver disease of undefined etiology. Five of the 12 patients were homozygous for the Z allele (ZZ) and two had the S allele with another allele (*S) different from Z. CONCLUSION: These results show that alpha-1-antitrypsin deficiency is relatively frequent in children with chronic hepatic disease of undefined etiology and/or low alpha-1-antitrypsin levels (41.6%). A correct diagnosis is important for effective clinical follow-up and for genetic counseling.

Reports on children presenting symptoms compatible with the chronic phase of Chagas disease are sporadic. We report a case of a 7-year-old boy who had megaesophagus and megacolon, both of them a consequence of the trypanosomiasis. The etiology was established by means of laboratory and histological features. Based on epidemiological data, the authors concluded that vertical transmission was the most probable route of acquisition. This diagnosis should be considered in children presenting similar complaints, even those living away from endemic areas.

Isoniazid and pyrazinamide are both well-known hepatotoxic drugs. When isoniazid is used, the hepatic lesion appears before than when pyrazinamide is used. This paper intends to relate a case of a 5-month-old patient who had lungs' and meningeal tuberculosis and who developed toxic hepatitis accomplished by hepatic failure while he was being treated with isoniazid, pyrazinamide and rifampicin. The clinic manifestations and the laboratory alterations were detected in the fifth day of treatment and the recovery was fast; and almost complete by the end of the first week, in which the use of isoniazid had been suspended. Although it was necessary to take the patient to the intensive care unit, he had a good recovery, without sequels.

BACKGROUND: Choledochal cyst is a rare abnormality usually found in infancy and childhood and mainly in females. Outcome depends on early diagnosis, complete resection of the cyst and proper hepaticoenterostomy.OBJECTIVE: The aim of this paper is to evaluate the outcome of 18 patients operated in ten years. METHODS: Retrospective chart review. RESULTS AND DISCUSSION: Age ranged between 20 days and 13 years (mean 3 years). Fifteen (83%) were female and 03 (17%) male. Signs presented included 15 (83%) with jaundice, 11 (61%) with dark urine, 10(55%) with pale colored stools, 09 (50%) with abdominal pain and palpable mass in only 02(11%). Ultrasonography identified the cyst in 14 (77%) patients. Endoscopic retrograde cholangio-pancreatography demonstrated a long common duct in three of four cases. Anatomical types were: 09 type I, 01 type II, 07 type IV and 01 type V. Except for one patient who had a type V cyst, all patients underwent cyst resection plus Roux-en-Y hepaticojejunostomy. There were two (11%) early postoperative deaths related to deterioration of liver function. Thirteen (86%) of the 15 patients available to follow-up were symptom-free without late complications at a mean period of three years, and two (14%) patients developed chronic pancreatitis.
ABSTRACT
Portal vein thrombosis represents one of the most frequent causes of portal hypertension in childhood. The aim of the present study was to describe the clinical and laboratorial characteristics of portal vein thrombosis in pediatric patient. We studied 26 children with diagnosis of portal vein thrombosis through splenoportography (two patients) and ultrasound scan (24 patients) which ages varied from 2 months to 11 years and 4 months (median-5 years and 3 months). Data of the patient history, physical and laboratories examination were used to a retrospective study which was done through medical record analysis. The main complaint of the examination was hematemesis, which was found in 57.6%. In 26.9% a possible risk factor for portal vein thrombosis was found [catheterization of the umbilical vein (four), sepsis (two), omphalitis (one)]. Splenomegaly was present in all cases and the associated illness to portal vein thrombosis were: hepatoportal sclerosis (three), cytomegalovirus infection (two), blastomycosis (two), virus C (two), virus B (one) and virus A (one). The time between the first bleeding and the examination at University of Campinas Hospital, in Campinas, SP, Brazil, varied from 0.23 months to 54 months with a median of 12 months. Only 11.5% of patients underwent the endoscopy with sclerotherapy before going to University of Campinas Hospital. Aminotransferases' activities were considered normal in 20 patients. We could conclude that: 1. The most frequent initial symptom was hematemesis. 2. The known risk factors for portal vein thrombosis were present in about 1/3 of the cases. 3. Laboratorial exams usually indicated absence of hepatocitic lesions. 4. The efforts towards sending the patient to a reference center were late with a delayed diagnostic and with delayed effective therapeutic conduct. 5. In about 50% of the cases there was PVT associated with other hepatic diseases.

The objective of this work was to study the gastric emptying (GE) of liquids in fasted and sucrose-fed rats with toxic hepatitis induced by acetaminophen. The GE of three test meals (saline, glucose and mayonnaise) was evaluated in Wistar rats. For each meal, the animals were divided into two groups (N = 24 each). Group I was fed a sucrose diet throughout the experiment (66 h) while group II was fasted. Forty-two hours after the start of the experiment, each group was divided into two subgroups (N = 12 each). Subgroup A received a placebo and subgroup B was given acetaminophen (1 g/kg). Twenty-four hours later, the GE of the three test meals was assessed and blood samples were collected to measure the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and acetaminophen. In group IB, the mean AST and ALT values were 515 and 263 IU/l, respectively, while for group IIB they were 4014 and 2472 IU/l, respectively. The mean serum acetaminophen levels were higher in group IIB (120 µg/ml) than in group IB (87 µg/ml). The gastric retention values were significantly higher in group IIB than in group IIA for all three test meals: saline, 51 vs 35 percent; glucose, 52 vs 38 percent and mayonnaise, 51 vs 29 percent(median values). The correlation between gastric retention and AST levels was significant (P<0.05) for group IIB for the three test meals: r = 0.73, 0.67 and 0.68 for saline, glucose and mayonnaise, respectively. We conclude that GE is altered in rats with hepatic lesions induced by acetaminophen, and that these alterations may be related to the liver cell necrosis caused by the drug

The schistosomiasis is an endemic disease in Brazil. The most frequent forms are: intestinal, hepatosplenic and hepatointestinal. Rare forms also manifest such as pseudo-tumoral form. The objective of this paper is to report a 8 years-old boy, from Minas Gerais State, with pseudo-tumoral schistosomiasis. He was submitted an exploratory laparotomy and a biopsy from abdominal mass was made. The histologic studies showed a chronic inflammatory process, with a large number of S. mansoni eggs. The treatment was a single-dose of oxaminiquine (20 mg/kg), with a positive evolution, with non-sequel observed after two years of follow-up.

Gastroesophageal reflux disease has been very often in children and one of its most critical complications is the peptic esophagitis disease. The diagnosis of peptic esophagitis is obtained based on the endoscopic changes and the histologic features. The pressure reduction of the lower esophageal sphincter is one of the elements of the esophagitis pathogenesis. The pressure is related with the length of the esophageal abdominal segment, which can be measured by ultrasonography. The research presented in this paper aims to relate ultrasonographic measurements of esophageal abdominal segment length with endoscopic changes and with esophageal biopsy obtained from children with gastroesophagel reflux disease. We submitted 16 children with gastroesophagel reflux disease, between 10 and 156 months old (median 63.5 months old), to endoscopy and to esophageal biopsy. We verified the following results from endoscopy and biopsy: six of the 16 patients had endoscopic peptic esophagitis and, in five of these (six patients), the same diagnosis was confirmed by biopsy. Ten of the 16 patients had normal endoscopy, but the biopsy of four of these 10 patients showed histologic changes compatible with esophagitis. We observed no relationship between endoscopy and biopsy, when all degrees of histologic change were used to diagnose esophagitis. However, we found high relationship when the mild histologic changes were considered as only a consequence of the reflux. We verified the following results from ultrasonography: five of the six patients with endoscopic peptic esophagitis and all patients with esophagitis determined by biopsy (excluding those with mild histologic changes) had reduced esophageal abdominal segment length. In conclusion, we have found relationship between endoscopic changes and histologic features in the diagnosis of esophagitis and correlation between the reduced esophageal abdominal segment length and the presence of esophagitis.

Hepatoportal sclerosis is the term used to name a clinicopathological condition responsible for non-chirrotic portal hypertension. A three cases report of children with hepatoportal sclerosis is presented associated with portal vein thrombosis. The first two patients presented as main complaint upper digestive hemorrhage and the third one was admitted for investigation of hepatosplenomegaly. The ultrasonographic exam revealed alterations indicative of extrahepatic portal vein thrombosis in the three cases. The patients underwent liver biopsy for they had presented altered liver enzymes. The main histological findings were: subintimal sclerosis, portal fibrosis and telangiectases of the intrahepatic venous branches, consistent with the diagnosis of hepatoportal sclerosis. The three patients showed good evolution, being the hemorrhage controlled in the first two cases through esclerotherapy of esophageal varices.
