Azathioprine is a drug commonly used for the treatment of inflammatory bowel disease, organ transplantation and various autoimmune diseases. Hepatotoxicity is a rare, but important complication of this drug. The cases reported to date can be grouped into three syndromes: hypersensitivity; idiosyncratic cholestatic reaction; and presumed endothelial cell injury with resultant raised portal pressures, venoocclusive disease or peliosis hepatis. The components of azathioprine, 6-mercaptopurine and the imidazole group, may play different roles in the pathogenesis of hepatotoxicity. The strong association with male sex, and perhaps with human leukocyte antigen type, suggests a genetic predisposition of unknown type. Many of the symptoms of hepatotoxicity, such as nausea, abdominal pain and diarrhea, can be nonspecific and can be confused with a flare-up of inflammatory bowel disease. As well, the subtype resulting in portal hypertension can occur without biochemical abnormalities. A 63-year-old man with Crohn's disease who is presented developed the rare idiosyncratic form of azathioprine hepatotoxicity, but also had a severe disabling steroid myopathy, peripheral neuropathy, resultant deep venous thrombosis and pulmonary embolism related to immobility, and a nosocomial pneumonia. His jaundice and liver enzyme levels improved markedly on withdrawal of the drug, returning to almost normal in five weeks. Treating inflammatory bowel disease effectively while trying to limit iatrogenic disease is a continuous struggle. Understanding the risks of treatment is the first important step. There must be a low threshold for obtaining liver function tests, especially in men, and alertness to the need to discontinue the drug or perform a liver biopsy should patients on azathioprine develop liver biochemical abnormalities, unexplained hepatomegaly or signs of portal hypertension.

A 17-year-old male with insulin-dependent diabetes mellitus was referred because of difficulties with diabetic control. Since his diagnosis at age 10, he has been hospitalized more than 60 times for diabetes or its complications, mostly ketoacidosis. He also has short stature, pubertal delay, and hepatomegaly, and on exam was uncooperative and hostile. The long-standing practice of binging and purging followed by vomiting was revealed. His condition was consistent with Mauriac syndrome. Addressing an associated eating disorder may improve diabetes control, but this combination significantly increases the risk of diabetic complications.

Recently, several class-related adverse events have been recognized with antiretroviral drugs. For nucleoside analogue reverse transcriptase inhibitors. (NRTI), lactic acidosis with hepatomegaly and hepatic steatosis have been reported. These appear to occur at a low frequency, but with a high fatality rate. We report a case of fatal lactic acidosis in a patient with acquired immunodeficiency syndrome (AIDS) treated with stavudine (d4T), lamivudine (3TC) and indinavir (IDV). A 48-year-old male AIDS patient was admitted with complaints of general fatigue and dyspnea. His medications at presentation included d4T, 3TC and IDV. Physical examination demonstrated icteric sclerae and abdominal tenderness with hepatomegaly. Laboratory data demonstrated a severe metabolic acidosis with an anion gap due to lactate accumulation. Despite intensive treatment, cardiorespiratory arrest occurred and this could not be resuscitated.

The first girl of an unrelated couple was noted to have failure to thrive since age 3 months, generalized hypotonia and weakness, hepatomegaly, hypoglycemia, and lactic acidosis at 4 months. She was found to have severe mitochondrial DNA (mtDNA) depletion and respiratory chain complex IV deficiency in both skeletal muscle and liver but without other common mtDNA mutations. Her younger brother developed vomiting at age 3 weeks and was diagnosed as having pyloric stenosis. His skeletal muscle and liver also showed severe mtDNA depletion. He developed generalized weakness and hypotonia, hepatomegaly, and lactic acidosis at age 3 months. Both siblings died of hepatic failure and hemorrhagic complication before 6 months of age. The brother also had chemical pancreatitis, which had not been reported before in mtDNA depletion in children. Severe mtDNA depletion may present with nonspecific symptoms such as vomiting, failure to thrive, and developmental delay; multiorgan involvement such as hepatomegaly, pancreatitis, and myopathy occurs later. Mitochondrial DNA depletion should be considered in the differential diagnosis in children with developmental delay or failure to thrive of unknown etiology.

A 48-year-old male who had a past history of alcoholic pancreatitis and diabetes mellitus was admitted to our hospital due to chills and vomiting, on August 13, 1998. His body temperature was 38.0 degrees C, and he had the disturbance of consciousness, tachypnea, tachycardia and hepatomegaly with tenderness. Laboratory findings showed highly inflammatory reactions, DIC and hepatorenal dysfunction. Abdominal CT and US revealed multiple liver abscess with portal vein thrombus. Serratia rubidaea was detected in the blood culture. SBT/CPZ and TOB were administered and he recovered. This is a rare case of Serratia rubidaea sepsis. It is also necessary to pay attention to Serratia infections as well as S. marcescens.

We describe a patient with impairment of mitochondrial fatty acid P-oxidation. A Japanese baby boy was delivered in the 38th week of gestation by emergency cesarean section due to fetal asphyxia. His birth weight was 1,985 g (<10th percentile), length 44.8 cm (<10th percentile), and head circumference 31.0 cm (10th percentile). His Apgar scores were 3 and 5 at 1 min and 5 min, respectively. Blood glucose was 12 mg/dl at 1 hour after birth, requiring glucose administration. On day 1 his serum CK was 20,780 IU/l, which was thought to be due to asphyxia. His serum CK levels gradually began to decrease. At 3 months of age, he sucked poorly, had poor body weight gain, and muscle hypotonia was observed. On day 117 his general condition was impaired, and marked hepatomegaly was observed. The blood glucose level was 43 mg/dl. The patient's urine was negative for ketone bodies. His serum triglyceride level was 3,670 mg/dl. Abdominal CT scan revealed a fatty liver. Serum levels of acyl carnitine from very-long chain fatty acid increased. On day 118 he died due to ventricular fibrillation. On necropsy, massive lipid deposition was observed in the liver, cardiac muscle, kidney, skeletal muscle, and intestinal mucosa. The ratio of very-long chain acyl-CoA dehydrogenase (VLCAD) activity for C16/C8 fatty acid was 0.50 (normal control 1.29), suggesting abnormal VLCAD. He was diagnosed as having impairment of mitochondrial fatty acid beta-oxidation, presumably due to the VLCAD deficiency.

A 30-year-old homosexual man presented with anemia and a several months history of recurrent fever, night sweats and weakness. His travel history included several stays in mediterranean countries during the recent years. Abdominal ultrasound showed massive splenomegaly, hepatomegaly and abdominal lymphadenopathy. A bone marrow aspirate revealed the presence of numerous Leishmania amastigotes, and bone marrow culture and polymerase chain reaction were also positive for Leishmania. In this case report epidemiological, immunological, diagnostic and therapeutic aspects of HIV-Leishmania coinfection are discussed with special emphasis on the impact of liposomal amphotericin B and highly active antiretroviral therapy on the treatment of HIV-leishmania-coinfection.

Dengue infection is hyperendemic in tropical countries especially in Thailand. Most dengue infections occur during childhood but some adults may remain susceptible to infection. About 30 per cent of dengue infection are reported in patients > 15 years old. Some pregnant women may also be susceptible to dengue and if they experience dengue infection, they can transmit the dengue viruses to their babies. The authors report two babies who developed mild dengue illness, dengue hemorrhagic fever (DHF) grade II, beginning on their 6th day of life. Both of them had low grade fever, hepatomegaly and generalized petechial rash. The first baby had Hct ranging from 46 to 40 per cent with minimal right pleural effusion. The lowest platelet count was 19,000 cells/mm3. His mother had dengue shock syndrome with masssive post partum bleeding. The second baby had dengue 2 infection while his mother had dengue fever. His Hct had also risen from 52 per cent to 61 per cent with right pleural effusion. His lowest platelet count was 7,000 cells/mm3. Both mothers and their babies had a complete recovery although the first baby had prolonged thrombocytopenia for two months.

Most cases of urticaria pigmentosa are confined to the skin, but visceral involvement and/or haematological abnormalities have been observed. It is still a matter of debate whether all forms of mastocytosis are true neoplasias or reactive hyperplasias. Familial inheritance of urticaria pigmentosa is rare. We report on a fraternal set with urticaria pigmentosa as part of a systemic mastocytosis. The first patient additionally revealed persistent thrombocytosis and splenomegaly. His brother developed urticaria pigmentosa, intermittent diarrhoea, hepatomegaly and asthma bronchiale associated with trisomy 21 (Down's syndrome). The association of mastocytosis with thrombocytosis has seldom been described. In our patient it preceded the development of systemic mastocytosis. The association with Down's syndrome has not been reported until now.

Fucosidosis is a rare, autosomal recessive lysosomal storage disorder caused by a severe deficiency of alpha-L-fucosidase. Here we present a 27-month-old male who was referred to us for evaluation of developmental delay, which was first detected at age six months. His past medical history was also remarkable for recurrent pulmonary infections and myoclonic seiures. His family history revealed that he was the first living child from a consanguineous marriage. He had a younger sister who died at five months of age from pneumonia who had facial resemblance to the proband, developmental delay and a congenital heart defect. Physical examination revealed length: 81 cm (25-50p), weight: 10.2 kg (25-50p), and head circumference: 49 cm (50-75p). He had a coarse face, hepatomegaly and generalized spasticity. His initial laboratory examination revealed negative urine screening column chromatography for mucopolysaccharidosis. His X-ray findings were consistent with mild form of dysostosis multiplex. Based on clinical and laboratory features, fucosidosis was suspected. Fucosidase enzyme activity was zero. In addition to fucosidosis, thyroid function tests indicated primary hypothyroidism. This is, to the best of our knowledge, the fourth case of fucosidosis diagnosed in Turkey.
