The purpose of the present study was to evaluate the effectiveness of fish oil in preventing tissue pathologies associated with monocrotaline (MCT) toxicity. Twenty-four weanling rats were randomly assigned to one of two groups: (1) 12 to a group fed a diet containing 15% (w/w) corn oil (control) and (2) 12 to a group fed a diet containing fish oil (13%) and corn oil (2%) as the source of fat. Rats were fed for 4 weeks prior to MCT treatment. Six rats in each group were subcutaneously injected with MCT and six injected with its vehicle (water) and all were continued on their respective diets. All rats were sacrificed 3 weeks after injection. In rats receiving MCT, we observed severe interstitial pneumonia, septal fibrosis, vasculitis with virtual obliteration of the lumen of the small arteries and arterioles, right ventricular hypertrophy (RVH), and hepatomegaly and hepatocyte vacuole formation. Dietary fish oil significantly reduced septal fibrosis and development of pneumonia. There was a slight, but statistically insignificant decrease in vasculitis and fish oil did not prevent RVH (pulmonary hypertension). In addition, fish oil effectively protected the MCT-treated rats from development of hepatocyte vacuoles (steatosis), hepatic inflammation and vasculitis, increased presence of fibroblasts and collagen deposition in the centrilobular and, to a lesser extent, in the periportal spaces. These results suggest that lung parenchymal inflammation can be attenuated without altering the course of development of pulmonary hypertension in the MCT model. These results also indicate that fish oil protects against inflammation and fibrosis in the lung and liver, and against hepatocyte vacuole formation in MCT-treated rats.

A report of 19 cases of serologically-proven dengue hemorrhagic fever (DHF) in infants aged 3-12 months who were admitted to the Department of Pediatrics, Chon Buri Regional Hospital, Thailand, during 1995 to 1998. Subjects were 8 males and 11 females, with the peak age of 8 months. Four cases (21%) had DHF and other common co-infections ie pneumonia (2 cases), Staphylococcus aureus sepsis (1 case) and Haemophilus influenzae meningitis (1 case). The clinical manifestations of the 15 DHF cases were high fever (100%), coryza (93.3%), hepatomegaly (80%), drowsiness (53.3 %), and vomiting (46.7%); rash was observed in only 27%; one-fifth developed febrile convulsions. Sites of bleeding were the skin (petechiae) 58%, gastrointestinal system (melena) 16%, and mucous membrane (epistaxis) 5%; thrombocytopenia and increased hematocrit (> or =20%) were noted in 95% and 84% respectively. The majority of the patients (18 cases, 95%) had primary infection; only one (5%) had secondary infection. The clinical severity of the DHF was Grade I, II, and III (dengue shock syndrome) in 21%, 47% and 32% of cases respectively. After appropriate and effective management, all the infants recovered fully.

Anewborn with a transient myeloproliferative disorder and a myeloid/natural killer cell leukemia phenotype is described. The blasts expressed CD7, CD33, CD34, CD56, and CD117 but did not react with cytoplasmic myeloperoxidase and were negative for cy CD22, HLA-DR, and CD90 expression. No megakaryoblastic surface markers were identified. The blast population disappeared from the peripheral blood and bone marrow within 2 months, but hepatomegaly and recurrent respiratory insufficiency persisted. The patient died of unilateral pneumonia in the third month of life. Neither extramedullary infiltration nor other hematologic signs of disease progression were found.

60 cases of endotoxic shock in obstetrics and gynecology in a 7 year period, January 1974 to December 1980 in Nigeria are reviewed. The most common and causative conditions were septic abortion, puerperal sepsis and pyelonephritis in pregnancy. The commonest cultured organism was Eschericha Coli. There were 33 deaths, giving a mortality rate of 55%, which falls within the range reported in the literature. The mortality rate in the institution where this study was conducted has shown a downward trend. Early surgery is advocated in those cases with infected retained products of conception and pyoperitoneum, and more liberal use of steroids, hypertonic glucose solution and digoxin, especially in patients with cardiac decompensation. The patients of the sample met the following criteria: 1) the occurrence of hypotension with consistent reading of 80/50 mm Hg or less; 2) demonstrable evidence of infection as determined by fever, hematological and bacteriological studies; and 3) the presence of persistent tachycardia. Conditions related to pregnancy accounted for 50% of of all cases. A significant finding was that 14 out of 18 patients with induced abortion had it at 2 weeks before admission. A majority of the patients in this study had subnormal temperature. The presence of jaundice, pneumonia, persistent oliguria and hepatomegaly are ominous signs accompanied by high mortality. Pulmonary factors in shock are important in determining patient survival as well as lung functions afterwards. The mortality in endotoxic shock remains high despite widespread use of fluids, antibiotic and steroid therapy, indicating that eliminating bacteria and restoring blood pressure are not the only considerations in treating shock. Insufficient nutrition may contribute to cardiorespiratory deterioration in the acutely ill patient; important physiological variables are improved by administration of hypertonic glucose solution, which leads to increased clearance of E. Coli from the blood.

Case records of HIV infected patients were analyzed for identifying neurological manifestations. Eight patients (7 males) were identified to have probable HIV encephalopathy (in a period of 24 months) as per the CDC revised classification system. Their ages ranged from one year to ten years. The neurological manifestations noted included-developmental delay (2 cases), seizures (6 cases), acute onset alteration of sensorium (4 cases), aphasia (2 cases), loss of vision (2 cases), focal neurological deficits (6 cases), brisk deep tendon reflexes (7 cases), extensor plantar responses (5 cases) and signs of cerebellar dysfunction (2 cases). Other clinical features included growth failure, microcephaly, fever, lymphadenopathy, hepatomegaly, splenomegaly, pneumonia, otorrhea and oral candidiasis. Cerebrospinal fluid studies were normal. The neuroimaging features included cerebral atrophy and ventricular dilatation, cerebral infarction, basal ganglia calcification and cerebellar atrophy. Childhood HIV infection may have a variety of neurological abnormalities. HIV infection should be suspected in children presenting with unexplained neurological manifestations and growth failure.

This is a retrospective study of congenital tuberculosis in Queen Sirikit National Institute of Child Health from 1979 to 1998. There were 9 patients with a mean birth weight of 2,500 grams (range 1,800-3,300). The onset of symptoms and age of diagnosis ranged from 7 to 42 (mean, 21) days and 14 to 75 (mean, 54) days after birth, respectively. The presenting signs and symptoms were fever (100%), poor feeding (100%), irritability (100%), failure to gain weight (100%), hepatomegaly (100%), splenomegaly (77.8%), cough (88.9%), respiratory distress (66.7%) and abdominal distension (77.8%). The tuberculin skin test reaction with > or = 10 mm induration was found in 2 of 8 patients. Their abnormal chest radiographs revealed bronchopneumonia 66.7 per cent, miliary pattern 33.3 per cent and multiple cystic lesion 11.1 per cent. The bacteriological study from gastric aspirate content for acid-fast bacilli (AFB) staining and culture were positive in 62.5 and 71.4 per cent respectively. Fatality rate was 33.3 per cent with no sequele found in the survivors. Congenital tuberculosis is a rare entity and difficult to give an early diagnosis. There should be a high index of suspicion for tuberculosis in those who had pneumonia and were unresponsive to aggressive antibiotics or had unexplained etiology.

We studied 73 Thai children with scrub typhus (median age 9 years, range 3-14 years, male:female ratio 1.8:1). Most patients (86%) lived in rural areas. They presented with subacute fever (median, 9 d) with vomiting (35%), hepatomegaly (59%), splenomegaly (18%), and tachypnea (26%). Skin rash (7%), eschar (7%), and history of mite bite were rare. Blood leucocyte counts were usually normal but 19% of patients were thrombocytopenic. Twenty (22%) patients had pneumonia and six (8%) had neurological involvement. Defervescence occurred a median of 1 d and 3 d after initiation of doxycycline and chloramphenicol, respectively, and these responses were more rapid than in those who received other antibiotics or no treatment (P < 0.001). There was one death. Only 55% of the patients were initially diagnosed as having scrub typhus.

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.

Inherited neutropenia is characterized by a decrease in the absolute number of circulating neutrophils and an increased susceptibility to infections. The current study was performed to determine the clinical and laboratory findings of Iranian patients with inherited neutropenias. Records of 26 patients (14 male, 12 female) with inherited neutropenia were reviewed in this study. The patients had been referred to Children's Medical Center, a referral center for immunodeficiency disorders in Iran, during a 22-year period (1981-2003). Primary immunodeficiency disorders of these patients were as follows: cyclic neutropenia (8 patients), Shwachman-Diamond syndrome (7 patients), Kostmann syndrome (6 patients), and Chediak-Higashi syndrome (5 patients). The mean absolute neutrophil count of patients was 398.2 +/- 259.3 cells/mm (range 74-1,152/mm) at the first visit. Twenty-one patients showed severe, four moderate, and one mild neutropenia. Sixteen of these patients had leukopenia, seven anemia, two thrombocytopenia, and one monocytosis. The most common presenting complaints in these patients were oral ulcer, otitis, pneumonia, diarrhea, cutaneous abscess, and oral candidiasis. The patients first manifested symptoms of infection suggesting neutropenia at a median age of 7.5 months (range 1 month to 10 years). During follow-up, respiratory infections developed in 24 cases, oral manifestations in 20 patients. The most common infections, in descending order of frequency, were otitis media, abscesses, pneumonia, oral ulcers, acute diarrhea, cutaneous infections, oral candidiasis, and periodontitis. Less frequent infections were sinusitis, cystitis, conjunctivitis, meningitis, and osteomyelitis. Nonspecific symptoms (hepatomegaly and splenomegaly) were also detected in 10 patients and 1 patient, respectively. Three patients died of recurrent infections. The infectious manifestations both at presentation and during follow-up in inherited neutropenia were similar. Although inherited neutropenias are rare, recurrent infections always deserves further evaluation for detecting such disorders.

The anti-arrhythmic agent amiodarone (AD) is associated with numerous adverse effects, but serious liver disease is rare. The improved safety of administration of daily low doses of AD has already been established and this regimen is used for long-term medication. Nevertheless, asymptomatic continuous liver injury by AD may increase the risk of step-wise progression of non-alcoholic fatty liver disease. We present an autopsy case of AD-induced liver cirrhosis in a patient who had been treated with a low dose of AD (200 mg/d) daily for 84 mo. The patient was a 85-year-old male with a history of ischemic heart disease. Seven years after initiation of treatment with AD, he was admitted with cardiac congestion. The total dose of AD was 528 g. Mild elevation of serum aminotransferase and hepatomegaly were present. Liver biopsy specimens revealed cirrhosis, and under electron microscopy numerous lysosomes with electron-dense, whorled, lamellar inclusions characteristic of a secondary phospholipidosis were observed. Initially, withdrawal of AD led to a slight improvement of serum aminotransferase levels, but unfortunately his general condition deteriorated and he died from complications of pneumonia and renal failure. Long-term administration of daily low doses of AD carries the risk of progression to irreversible liver injury. Therefore, periodic examination of liver function and/or liver biopsy is required for the management of patients receiving long-term treatment with AD.
