Generalized adenopathy and splenomegaly developed in an 18-year-old youth after a severe tonsillitis followed by headache, tiredness and weight loss for several weeks. Infectious mononucleosis (acute Epstein-Barr virus infection) was confirmed by the demonstration of virus-specific antibodies. A reticulocytosis (24%), decreased haptoglobin concentration (0.6 mg/dl) and increased lactate dehydrogenase activity (657 U/l) indicated marked haemolysis. The bone marrow showed increased erythropoiesis with abnormal maturation. Antibodies against triosephosphate isomerase and against blood group marker "i" were demonstrated in the patient's serum. Antibodies against triosephosphate isomerase from the patient's serum were purified by affinity-chromatography. They strongly reacted with the patient's erythrocytes and under complement activation induced an increased 51Cr liberation from marked erythrocytes. No corresponding effect of anti-i-antibodies was noted at 37 degrees C. With the fall in antibodies against triosephosphate isomerase the haemolysis receded and the patient became free of symptoms after 7 weeks.

Confirmation of a causal relationship between hemolytic-uremic syndrome (HUS) and verotoxin-producing Escherichia coli (VTEC) infection is provided by the case of a 22-year-old West German woman. The patient presented with fatigue, nausea, and headache. Ultrasonography revealed enlarged kidneys, and laboratory investigations showed uremia, hemolytic anemia, lactate dehydrogenase, haptoglobin below the detection limit, and thrombocytopenia. She received hemodialysis and drug treatment (heparin, dopamine, and furosemide). To investigate the kinetics of the humoral response to verotoxin, the patient was followed for 3 months. Fecal specimens on day 23 yielded E coli serotype 0111:NM, and stool filtrates on days 16 and 23 showed highly cytotoxic activity for HeLa cells. While the patient's initial serum showed a high IgM immune response against purified Shiga toxin, there was a steady decline in IgM and steady increase in IgG antibodies over the ensuing 3 months. These findings are suggestive of a recent infection by a verotoxin-producing organism. This is the 1st reported case of VTEC-associated HUS with e coli 0111 infection in an adult, and the patient's 4-year history of oral contraceptives (OCs)--ethinyl estradiol and chlormadinoneacetate--is considered to be of etiologic significance. The diminished antibody coating of bacteria in the urinary tract of OC users may have facilitated invasion of verotoxin across the mucosal barrier in this patient. Severe hypertension has been reported previously in OC users with HUS. It is speculated that verotoxin may trigger HUS in longterm OC users, initiating vasoconstriction and microangiopathic hemolysis.

Efficacy and safety of tretinoin (all-trans retinoic acid, ATRA, Ro01-5488) for refractory and relapsed acute promyelocytic leukemia were studied by multi-institutional study in Japan. 22 out of 27 (81.5%) patients with previously untreated who were intolerable to chemotherapy, relapsed and refractory were achieved CR. And 4 out of 11 (36.4%) in relapsed patients who received ATRA remission induction therapy previously responded. Side effects, such as dryness of the lip and skin, headache, increase of triglyceride, beta-lipoprotein and lactate dehydrogenase, were observed in 36 of 41 eligible patients (87.8%) but these were well tolerated. In addition to these, hyperleukocytosis in 4 cases and retinoic acid syndrome in 3 cases were observed. However, all patients were prescribed tretinoin again by adequate management.

A 61-year-old man became ill with a fever of 39.4 degrees C, decreased exercise tolerance and headache as well as chest pain. Physical examination 3 weeks after the onset of symptoms merely revealed irregular heart rate at 100 beats/min. Erythrocyte sedimentation rate was increased (30/61 mm), as were serum bilirubin, lactate dehydrogenase, alkaline phosphatase, gamma-GT and C-reactive protein. The ECG showed atrial fibrillation with a rapid and irregular ventricular rate, as well as ventricular extrasystoles (Lown type IIIA), there were no abnormal findings on either the chest radiography or transthoracic echocardiography. Antiarrhythmic treatment brought about atrial flutter with 4:1 a-v conduction. Transoesophageal echocardiography now revealed vegetation on the pulmonary valve and microthrombi in the left atrial appendage. Ten days after starting intravenous penicillin G (10 mega units four times daily), gentamycin (60 mg three times daily) and heparin (30,000 units over 24 h) sinus rhythm was restored, the vegetation had got smaller and no thrombi were demonstrated. After 27 days antibiotic treatment was changed to oral penicillin V. After 4 weeks the patient was discharged symptom-free.

The HELLP syndrome is a serious complication of pregnancy, found most frequently in conjunction with severe preeclampsia. The incidence of this disease in preeclampsia is between 2 and 12%. The diagnosis is based on typical laboratory findings, i.e. haemolysis--H, elevated liver enzymes--EL and a low-platelet count--LP. Haemolysis is defined as microscopic finding of an abnormal peripheral blood smear, elevated total bilirubin above 1.2 mg/dl and elevated lactate dehydrogenase above 40 mukat/l. Transaminases (AST above 4.2 mukat/l) are also elevated. For HELLP a low platelet count is typical (number of thrombocytes less than 100,000 mm3). The symptoms include above all pain in the epigastrium, in the right subcostal area, nausea and vomiting. Non-specific symptoms resembling viroses are lassitude, general weakness, headache and fatigue. A correct differential diagnosis and early assessment of the diagnosis are decisive for starting treatment which can prevent the development of serious complications such as disseminated intravascular coagulopathies and hepatorenal failure. Treatment of the HELLP syndrome is symptomatic with the objective to stabilize the general condition of the mother, improved haemodynamic conditions and the impaired haemocoagulation. A very important therapeutic step is early termination of pregnancy which depends on ther mother's condition and the condition of the foetus with regard to gestational age.

We present a retrospective review of Hantavirus infection in the emergency department. Thirteen cases of Hantavirus infections with renal syndrome from July 1989 to August 1999 were analysed. The diagnosis was confirmed by detection of Hantavirus antibodies in all cases. Fever, chills and headaches were universally present. Intense back pain was associated in 77% of the patients. Thrombocytopenia, abnormal urinalysis, hypertransaminasaemia, increased lactate dehydrogenase were the principal biological patterns. All these parameters returned to their normal level, and all the patients recovered a normal renal function without sequels. The management is supportive. Only one patient in our series had to be dialysed. Hantavirus disease should be included in the differential diagnosis of acute renal failure with thrombocytopenia, particularly in patients with suspected exposure in known endemic areas. The differential diagnosis of any perplexing case of undifferentiated febrile illness with acute renal failure and thrombocytopenia should include Hantavirus infection.

Severe acute respiratory syndrome (SARS) is a highly infectious disease with a significant morbidity and case fatality. The major clinical features include persistent fever, chills/rigor, myalgia, malaise, dry cough, headache and dyspnoea. Less common symptoms include sputum production, sore throat, coryza, dizziness, nausea, vomiting and diarrhoea. Older subjects may present with decrease in general well-being, poor feeding, fall/fracture and delirium, without the typical febrile response. Common laboratory features include lymphopenia with depletion of CD4 and CD8 lymphocytes, thrombocytopenia, prolonged activated partial thromboplastin time, elevated D-Dimer, elevated alanine transminases, lactate dehydrogenase and creatinine kinase. The constellation of compatible clinical and laboratory findings, together with the rather characteristic radiological features especially on HRCT and the lack of clinical response to broad-spectrum antibiotics, should quickly arouse suspicion of SARS. The positivity rates of urine, nasophargyngeal aspirate and stool specimen have been reported to be 42%, 68% and 97%, respectively, on day 14 of illness, whereas serology for confirmation may take 28 days to reach a detection rate above 90%. Recently, quantitative measurement of blood SARS CoV RNA with real-time RT-PCR technique has been developed with a detection rate of 80% as early as day 1 of hospital admission but the detection rates drop to 75% and 42% on day 7 and day 14, respectively.

Severe acute respiratory syndrome (SARS) is a newly emerged infectious disease with a significant morbidity and mortality. The major clinical features include persistent fever, chills/rigor, myalgia, malaise, dry cough, headache, and dyspnoea. Older subjects may present without the typical febrile response. Common laboratory features include lymphopenia, thrombocytopenia, raised alanine transaminases, lactate dehydrogenase, and creatine kinase. The constellation of compatible clinical and laboratory findings, together with certain characteristic radiological features and lack of clinical response to broad spectrum antibiotics, should arouse suspicion of SARS. Measurement of serum RNA by real time reverse transcriptase-polymerase chain reaction technique has a detection rate of 75%-80% in the first week of the illness.

Stimulation of healthy granulocyte donors allows the collection of therapeutic doses of granulocytes. The stimulation with G-CSF alone was compared with G-CSF plus dexamethasone. Blood samples were drawn at baseline, at leukapheresis, and at follow-up visit. Donors answered a questionnaire to evaluate side effects of the stimulation regimen. The combination of G-CSF and dexamethasone resulted in higher WBC count than G-CSF alone (39.4 +/- 7.8 vs. 34.8 +/- 8.3/nl). Glucose (136 +/- 45 mg/dl) and lactate dehydrogenase (195 +/- 38) increased significantly after stimulation with G-CSF plus dexamethasone but returned to baseline levels at the follow-up visit. Generally, stimulation was well tolerated by the donors. A higher rate of mild bone pain and headache was experienced in donors stimulated with G-CSF plus dexamethasone than in donors receiving G-CSF alone. Fatigue and myalgia were reported at similar rates in both groups. A high proportion of the donors stated that they would accept a further stimulation and granulocyte donation. At the follow-up visit, blood counts and chemistry had returned to normal values.

Children are susceptible to infection by SARS-associated coronavirus (SARS-CoV) but the clinical picture of SARS is milder than in adults. Teenagers resemble adults in presentation and disease progression and may develop severe illness requiring intensive care and assisted ventilation. Fever, malaise, cough, coryza, chills or rigor, sputum production, headache, myalgia, leucopaenia, lymphopaenia, thrombocytopaenia, mildly prolonged activated partial thromboplastin times and elevated lactate dehydrogenase levels are common presenting features. Radiographic findings are non-specific but high-resolution computed tomography of the thorax in clinically suspected cases may be an early diagnostic aid when initial chest radiographs appear normal. The improved reverse transcription-polymerase chain reaction (RT-PCR) assays are critical in the early diagnosis of SARS, with sensitivity approaching 80% in the first 3 days of illness when performed on nasopharyngeal aspirates, the preferred specimens. Absence of seroconversion to SARS-CoV beyond 28 days from disease onset generally excludes the diagnosis. The best treatment strategy for SARS among children remains to be determined. No case fatality has been reported in children and the short- to medium-term outcome appears to be good. The importance of continued monitoring for any long-term complications due to the disease or its empiric treatment, cannot be overemphasised.
