To find the incidence, markers and nature of complications of typhoid fever, we studied 102 children with cultures positive for Salmonella typhi in a cross-sectional study, prospectively, over a period of almost 5 years. All isolates were sensitive to commonly used antibiotics. One third of these children developed complications which included: anicteric hepatitis, bone marrow suppression, paralytic ileus, myocarditis, psychosis, cholecystitis, osteomyelitis, peritonitis, pneumonia, haemolysis, and syndrome of inappropriate release of antidiuretic hormone (SIADH). Twelve children developed multiple complications. If hepatitis is excluded from the complications, the rate of complications in bacteriologically confirmed cases of typhoid fever drops to 11 per cent. These complications were not related to: the age or sex of patients, duration of illness before admission, use of antibiotics before admission, nutritional status, level of 'O' or 'H' titre, presence of IgM or IgG antibodies, or treatment with chloramphenicol or ampicillin. Children with splenomegaly, thrombocytopenia or leukopenia were more likely to develop complications.

A 6-year-old girl had fever, abdominal pain, and severe anicteric hepatitis during intravenous oxacillin therapy for staphylococcal osteomyelitis. She had greatly elevated liver enzymes, prolonged prothrombin time, leukopenia, and eosinophilia. Clinical symptoms resolved and laboratory data returned to normal after withdrawing oxacillin and substituting cefazolin. This hepatotoxicity appears to be specific to oxacillin and not to other beta-lactams. Monitoring liver function tests during oxacillin therapy, especially in patients receiving prolonged treatment, may be warranted.

Sarcoidosis is a systemic granulomatous disease of unknown etiology that has a wide variety of clinical manifestation. Lung involvement may slowly undergo pulmonary fibrosis. Chronic sarcoid arthritis is a rare, usually non destructive arthropathy; may be a mono, oligo or polyarthritis. Knees, ankles, shoulders, wrists and small joint of the hands and feet may be involved. It can involve skin, eyes, exocrine glands such as salivary and lacrimal glands, and many other tissues. We describe the case of a 77 years old woman with a history of rhinopharyngitis with epistaxis and chronic laryngitis since youth; a dry mouth and throat, a erythematous, infiltrative skin lesion in the forehead and in the nape of the neck, a purple lesion of the left ear and nose, skin dystrophy of the hands from 30 years before. She underwent an operation for a left femoral fracture with hemotransfusion 14 years ago. Then she developed a polyarthritis of the small joints of the hands (II, III and IV right DIP, I, III, e V left DIP; III and V bilateral PIP), knees, tarsi, toes and left elbow. An HCV chronic hepatitis was discovered 6 years before. She is affected by productive cough, dysphonia, dyspnoea at rest, fever, headache and asthenia for over 5 years. Laboratory examination revealed leukopenia, HCV hepatitis with anti HCV, HCV-RNA, transaminases elevated and cryoglobulinemia. HCV may be involved in the etiopathogenesis of rheumatic diseases, lung fibrosis and may moreover contribute to the onset or progression of sarcoidosis; the possible pathogenesis is discussed.

Since the discovery of hepatitis C virus (HCV) in 1989, significant advances have been made in our understanding of this important viral pathogen. Children at risk for HCV infection include recipients of potentially contaminated blood products and organ transplants, and infants born to HCV-infected mothers. Chronic HCV infection is usually asymptomatic in children but active hepatitis, cirrhosis and hepatocellular carcinoma can occur. The development of treatment strategies for chronic hepatitis C in children has directly evolved from clinical trials in adults. Sustained virologic response, defined by undetectable HCV RNA in serum 24 wk after completion of treatment, occurs in approximately 36% of children treated with conventional interferon alone and in about 50% of those given conventional interferon in combination with ribavirin. Pegylated interferon-based treatment regimens are better than those based on conventional interferon in adults but little is known about pegylated interferon in children. Factors associated with a favorable response to antiviral therapy in children are similar to those in adults and include infection with HCV genotype 2 or 3 and low pretreatment serum HCV RNA levels. Treatment related adverse events in children include 'flu-like' syndrome, fatigue, anorexia, weight loss, depression, anemia, leukopenia and thrombocytopenia.

Influenza A virus is well known for its capability for genetic changes either through antigen drift or antigen shift. Antigen shift is derived from reassortment of gene segments between viruses, and may result in an antigenically novel virus that is capable of causing a worldwide pandemic. As we trace backwards through the history of influenza pandemics, a repeating pattern can be observed, namely, a limited wave in the first year followed by global spread in the following year. In the 20th century alone, there were three overwhelming pandemics, in 1918, 1957 and 1968, caused by H1N1 (Spanish flu), H2N2 (Asian flu) and H3N2 (Hong Kong flu), respectively. In 1957 and 1968, excess mortality was noted in infants, the elderly and persons with chronic diseases, similar to what occurred during interpandemic periods. In 1918, there was one distinct peak of excess death in young adults aged between 20 and 40 years old; leukopenia and hemorrhage were prominent features. Acute pulmonary edema and hemorrhagic pneumonia contributed to rapidly lethal outcome in young adults. Autopsies disclosed multiple-organ involvement, including pericarditis, myocarditis, hepatitis and splenomegaly. These findings are, in part, consistent with clinical manifestations of human infection with avian influenza A H5N1 virus, in which reactive hemophagocytic syndrome was a characteristic pathologic finding that accounted for pancytopenia, abnormal liver function and multiple organ failure. All the elements of an impending pandemic are in place. Unless effective measures are implemented, we will likely observe a pandemic in the coming seasons. Host immune response plays a crucial role in disease caused by newly emerged influenza virus, such as the 1918 pandemic strain and the recent avian H5N1 strain. Sustained activation of lymphocytes and macrophages after infection results in massive cytokine response, thus leading to severe systemic inflammation. Further investigations into how the virus interacts with the host's immune system will be helpful in guiding future therapeutic strategies in facing influenza pandemics.

Streptococcus pneumoniae ( S. pneumoniae ) has been associated with hemolytic uremic syndrome (HUS), which is an unusual but serious disease in childhood. We conducted a retrospective review of children aged less than 18 years with S. pneumoniae -associated HUS in northern Taiwan from January 2000 to June 2005. The demographic characters, clinical courses, and outcomes were analyzed. Seven children (three girls, four boys) with S. pneumoniae -associated HUS were studied. The median age at onset of HUS was 40 months (range: 25-60 months). The median duration of hospital stay was 36 days (range: 15-50 days). The interval between the onset of illness attributable to S. pneumoniae and the development of HUS was around 1-2 weeks. The onset of oliguria developed within 2 weeks after illness. Six patients required dialysis with median duration of 16 days. Three patients had leukopenia as the initial presentation. All seven patients had pneumococcal pneumonia complicating with empyema, and two of them received decortication via video-assisted thoracoscopic surgery. Between patients who needed dialysis or not, there was no significant difference in age, sex, duration of thrombocytopenia, incidence of extra-renal complications, such as hepatitis, pancreatitis, and hypertension, and length of hospital stay. The seven patients survived with normal renal function. HUS is a potentially fatal complication of S. pneumoniae infection. Clinicians managing patients with pneumococcal pneumonia with empyema accompanied by leukopenia should beware of the development of HUS. The long-term prognosis for recovery of renal function appears to be good in these patients in northern Taiwan.

In this study one spleen-intact dog (A) and two splenectomised dogs (BSE, CSE) were infected with Babesia canis. All animals developed an acute disease characterised by fever, haemoglobinuria and anaemia, the latter being more severe in the splenectomised dogs. Fever and parasitised red blood cells were detected for three days after imidocarb treatment in the splenectomised animals. Haematological abnormalities included regenerative anaemia, thrombocytopenia and leukopenia (due to neutropenia and lymphopenia) in the acute phase, soon followed by leukocytosis, neutrophilia and left shift a few days later. Acute hepatopathy was detected in all dogs with elevated ALT activity, which was more seriously altered in the splenectomised dogs. Diffuse changes in liver structure and hepatomegaly were seen by ultrasonography. Liver biopsy and histology revealed acute, non-purulent hepatitis in the splenectomised dogs. Both splenectomised dogs were successfully cured after collection of 400 ml highly parasitised blood, proving that large-amount antigen production is possible with rescuing the experimental animals. Whole blood transfusion, imidocarb and supportive care with infusions, antipyretics, glucocorticoids and diuretics were applied. The spleen-intact dog clinically recovered after receiving supportive treatment, with no imidocarb therapy. Microbial infections developed in both splenectomised animals (BSE: haemobartonellosis, CSE: osteomyelitis caused by Escherichia coli), probably as a consequence of immunosuppression after splenectomy and glucocorticoid therapy.

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.

Erythema infectiosum is the main manifestation of human parvovirus B19 infections. Further B19-related diseases commonly associated with the acute infection are flue-like symptoms, transient aplastic crisis, transient arthralgias, leukopenia and thrombocytopenia, spontaneous abortion and hydrops fetalis in pregnant women. Hepatitis, myocarditis, meningitis, encephalitis as well as pure red cell anemia may occur occasionally. In addition parvovirus B19 infections have been frequently described as cause or trigger of various forms of autoimmune diseases affecting all blood cell lines, joints, connective tissue, uvea, large and small vessels. Molecular mimicry may be one major contribution to the appearance of autoimmune antibodies, f.e. antiphospholipid and antineutrophil cytoplasmic antibodies as well as antinuclear antigens. These mechanisms implicated in the pathogenesis of parvovirus B19 triggered autoimmune diseases, especially focused on the development of antiphospholipid antibodies will be discussed in this short review.

Herpes simplex hepatitis is a rare cause of acute hepatitis in immunocompetent patients. Herpes hepatitis presents with nonspecific symptoms like fever, loss of appetite, vomiting, nausea and abdominal pain. Elevated transaminase values with leukopenia, relatively low bilirubin level and mucosal herpetic lesions often provide clues to the diagnosis. We describe an immunocompetent woman with herpes simplex hepatitis presenting with multiple hypodense lesions in the liver and mucocutaneous herpetic lesions.
