We retrospectively studied the records of 6 Malaysian children who were diagnosed with Alagille Syndrome (AGS) according to this criteria from January 1999 to January 2001, at the Institute of Paediatrics, Kuala Lumpur Hospital. Four patients (66%) had a positive family history. Thirteen individuals (6 patients and 7 relatives) were diagnosed with AGS in these 5 families. Only 6/13 (46%) of them presented with liver involvement. All 6 patients presented with typical facies and cholestasis (100%). Three (50%) presented with portal hypertension (PHT) with synthetic liver dysfunction (1 died), 1/6 (17%) have PHT and normal synthetic liver function. Two have cleared their jaundice but have biochemical evidence of hepatitis and hepatomegaly, four have congenital heart disease 5/6 posterior embryotoxon, 2/6 butterfly vertebrae, 4/6 hyperlipidaemia and 4/6 failure to thrive. One patient has a Jagged-1 gene disruption at the translocation breakpoint locus 20p12.3 2n = 46,XX,t(12.20) (q22, p12.3). 5/6 (83%) are still alive. Two-thirds of our patients developed chronic liver disease by 3 years of age. Two-thirds of the index patients have a family history. Only 46% of individuals in these families have clinical evidence of liver involvement. Mortality depends on cardiac/renal disease, end-stage liver failure and intercurrent infection.

Splenomegaly is a common finding in beta-thalassemia; however, its hemodynamic features and its potential correlations with high output state and hepatic disorders, both also frequent in thalassemia, have not yet been assessed in these patients. Eight beta-thalassemia patients with the indication for splenectomy and no symptoms or signs of heart disease, aged 25.6+/-5.5 years, were studied. Preoperative assessment included hematological profile, liver biology, hepatitis virus serology, and echocardiography. During splenectomy, splenic artery blood flow and splenic vein pressure were directly measured and liver biopsies were taken. Preoperative echocardiographic data were compared with those of 34 healthy controls. The preoperative cardiac index was significantly elevated in patients (4.8+/-1.3 vs 3.4+/-1.1 l/min per m2 in controls, p<0.001). Splenic blood flow, although increased, was not particularly high, being 285+/-56 ml/min or 0.13+/-0.04 ml/min per g of splenic mass, representing 4.1+/-0.9% of total cardiac output (CO). Splenic vein pressure was considerably elevated (29.7+/-5.5 cmH2O). Hepatic fibrosis, iron deposition, and extramedullary foci were found in all eight biopsies. Serology was positive in five of eight cases. beta-thalassemia patients with extensive splenomegaly requiring splenectomy are characterized by high output state, increased splenic blood flow, which probably makes a limited contribution to CO elevation, and portal hypertension, manifest by increased splenic vein pressure and hepatic histopathological abnormalities.

Ranitidine may cause liver injuries ranging from transient, subclinical serum transaminases increase every 100-1,000 treated patients to cholestatic hepatitis in less than 1/100,000. Other H2-receptor antagonists are more dangerous: 11 toxic hepatitis cases have been reported as adverse effect after 1 year of marketed ebrotidine. A 75-year-old male with ischemic cardiopathy history was started on an 8 days treatment of oral ranitidine due to pirosis, without any other changes of therapy; 48 h after drug withdrawal, light-coloured stools, dark urine and icteric scleras developed. On hospital admission, 10 days later, physical examination showed slight hepatomegaly and severe jaundice with skin excoriations followed by serum mixed bilirubin further increase and aminotransferases activities mild rise. Total bilirubin peaked at 381.33 mmol/l (5.1-17.1) and progressively returned to normal, after discharge home, in 3 months and now, 1 year later, there is no sign of liver disease. Ultrasonographic biliary anomalies and the most frequent causes of liver damage were excluded. Liver biopsy confirmed ranitidine as the most likely cause of liver toxicity since histological and ultramicroscopical study revealed a drug-induced picture. We report a rare case of intrahepatic cholestasis jaundice related to ranitidine, a widely used drug. Diagnosis would need an ethically unacceptable rechallange test.

On rare occasions the first manifestation of heart disease is jaundice, caused by passive congestion of the liver or acute ischaemic hepatitis. We looked for this presentation retrospectively in 661 patients referred over fifty-six months to a 'jaundice hotline' (rapid access) service. The protocol included a full clinical history, examination and abdominal ultrasound. Those with no evidence of biliary obstruction had a non-invasive liver screen for parenchymal liver disease and those with suspected heart disease had an electrocardiogram, chest X-ray and echocardiogram. 8 patients (1.2%), bilirubin 31-79 micromol/L, mean 46 micromol/L, had a primary cardiac cause for their jaundice. All had dyspnoea, an increased cardiothoracic ratio on chest X-ray and an abnormal electrocardiogram. The jugular venous pressure was raised in the 3 in whom it was recorded. In 6 patients the jaundice was attributed to hepatic congestion and in 2 to ischaemic hepatitis. All patients had severe cardiac dysfunction. Jaundice due to heart disease tends to be mild, and a key feature is breathlessness. The most common mechanism is hepatic venous congestion; ischaemic hepatitis is suggested by a high aminotransferase.

The congenitally corrected transposition of the great arteries is a rare form of congenital heart disease, with survival beyond the 6th decade of life being rare. Even more unusual is its presentation alone, without any other form of congenital heart disease. Ischemic hepatitis is a rare entity characterized by an elevation of transaminasas and a centrilobular necrosis due to a reduction in hepatic blood flow, generally of reversible evolution. The authors present a case of ischemic hepatitis in an 81-year-old patient with congenitally corrected transposition of the great arteries. The fatal evolution of the episode and the longevity of the patient are both notable. We comment on the clinical and diagnostic aspects of both entities.

A 65-year-old man diagnosed with hepatitis C virus-positive hepatitis and severe valvular heart disease was scheduled to undergo cardiac valve replacement. We then found hepatocellular carcinoma in the liver. Because of his severe cardiac dysfunction, we treated him surgically with radiofrequency ablation for the hepatocellular carcinoma only. We continued medical treatment of the heart disease. He hoped to undergo with cardiac surgery one year later for the cardiac dysfunction. There was no evidence of tumor recurrence. We informed him that cardiac surgery requiring extracorporeal circulation might lead to tumor recurrence. He agreed to cardiac valve replacement, and the surgery was successful. Recurrent hepatocellular carcinoma was found in the liver 1 month after the surgery. Over the next month, the tumor progressed rapidly, showing portal vein thrombi. We believe the use of extracorporeal circulation in particular triggered the rapid growth of the recurrent hepatocellular carcinoma. This is the first report of a recurrent hepatocellular carcinoma associated with hepatitis C virus that progressed extensively after cardiac surgery.

The life expectancy of patients with thalassemia major has significantly increased in recent years, as reported by several groups in different countries. However, complications are still frequent and affect the patients' quality of life. In a recent study from the United Kingdom, it was found that 50% of the patients had died before age 35. At that age, 65% of the patients from an Italian long-term study were still alive. Heart disease is responsible for more than half of the deaths. The prevalence of complications in Italian patients born after 1970 includes heart failure in 7%, hypogonadism in 55%, hypothyroidism in 11%, and diabetes in 6%. Similar data were reported in patients from the United States. In the Italian study, lower ferritin levels were associated with a lower probability of experiencing heart failure and with prolonged survival. Osteoporosis and osteopenia are common and affect virtually all patients. Hepatitis C virus antibodies are present in 85% of multitransfused Italian patients, 23% of patients in the United Kingdom, 35% in the United States, 34% in France, and 21% in India. Hepatocellular carcinoma can complicate the course of hepatitis. A survey of Italian centers has identified 23 such cases in patients with a thalassemia syndrome. In conclusion, rates of survival and complication-free survival continue to improve, due to better treatment strategies. New complications are appearing in long-term survivors. Iron overload of the heart remains the main cause of morbidity and mortality.

The purpose of this study was to evaluate certain clinical aspects of hyperthyroidism in Albania, which is an iodine deficient country, as it is known that iodine intake may influence the type of thyroid hyperfunction. The files of sixty-six patients with thyrotoxicosis who were hospitalised for their disease were retrospectively analysed. 59.1% of these patients suffered from toxic multinodular goiter, 27.3% from Grave's disease (toxic diffuse goiter), 10.6% from toxic adenoma, 1.5% from iodide-induced hyperthyroidism and 1.5% from transient hyperthyroidism due to subacute thyroiditis. There was an increased female to male ratio (83.3% vs 16.7%, respectively, p<0.001). 83.9% of all hyperthyroid patients lived in cities, while 16.1% lived in villages. Ophthalmopathy was found in 11.1% of patients with Graves' disease, and thyrotoxic heart disease was found in 14% of patients with thyrotoxicosis. 71.9% of all patients with hyperthyroidism were treated with propylthiouracil (PTU), while 28.1% of them were treated with methimazole; 67.2% of all these patients also received propranolol hydrochloride, while 32.8% were prescribed atenolol. Compliance was lower than that reported in other studies as only 41% of all patients received their treatment regularly. Side effects from treatment with antithyroid drugs were as follows: 4.1% (2/48) of patients treated with propylthiouracil presented leukopenia with agranulocytosis, and 6.1% of them toxic hepatitis, while 11.1% (2/18) of patients treated with methimazole presented agranulocytosis. In conclusion, the mode of presentation and side effects of hyperthyroidism appears to be different in Albania when compared with other countries, probably as a result of iodine deficiency and/or possibly nutritional status. Compliance with treatment is lower than that reported in other series, while antithyroid drug side effects seem to be more frequent. The latter observation may be due to the fact that only hospitalised patients were analysed in this study.

Oxidative DNA damage is one of the most important and most studied mechanisms of disease. It has been associated with a range of terminal diseases such as cancer, heart disease, hepatitis, and HIV, as well as with a variety of everyday ailments. There are various mechanisms by which this type of DNA damage can be initiated, through radiation and chemical oxidation, among others; however, these mechanisms have yet to be fully elucidated. A HPLC-UV-EC study of the oxidation of DNA mediated by nickel(II) obtained results that show an erratic, almost oscillatory formation of 8-oxoguanine (8-oxoG) from free guanine and from guanine in DNA. Sporadic 8-oxoG concentrations were also observed when 8-oxoG alone was subjected to these conditions. A HPLC-MS/MS study showed the formation of oxidised-guanidinohydantoin (oxGH) from free guanine at pH 11, and the formation of guanidinohydantoin (GH) from DNA at pH 5.5.

This article explored the notion that media depictions of health concerns come in one of two formats: challenge and stigma. After explicating the five features that should appear in challenge format and the seven features of stigma formats, we analyzed the content of health messages in magazines, brochures, and posters (n = 75) in a metropolitan area. The results of a two-factor confirmatory factor model showed that the five suggested features for challenge formats did, indeed, appear together (alpha = .76), and the seven features for stigma formats, also, appeared together (alpha = .90), and showed no residual relationship. In other words, the results suggest that media depictions of health topics appear in either challenge or stigma formats (r = - .87). Health issues appearing in magazine advertisements and articles presented messages in challenge formats, while brochures and posters from largely nonprofit and government groups depicted health issues in stigma formats. Some health topics appeared most often in challenge formats (including cancer, heart disease, and scoliosis), while others appeared in stigma formats (including tuberculosis, hepatitis, smoking, and sexually transmitted diseases [STDs]). Findings suggest that media depictions of health differ, and the implications of stigma and challenge formats are discussed.
