Details are given of all serologically confirmed Mycoplasma pneumoniae infections in children referred to Bristol hospitals during an epidemic lasting 18 months. 44 children, many below school age, had lower respiratory infections. The majority had cough and malaise which had failed to respond to antibiotics given before referral. Chest x-rays showed no pathognomonic features: segmental or patchy consolidation was common; 3 cases of lobar consolidation. Cold agglutinins were raised in 9 out of 12 cases. In the majority of cases the total leucocyte count was normal and the absolute neutrophil count raised. Mean duration of symptoms was 4.2 weeks (range 1-16). Treatment with erythromycin or tetracycline appeared to have little effect in most cases. Seven nonrespiratory manifestations were seen in 6 children. These were meningitis (2 cases), Stevens-Johnson syndrome (4 cases, 1 case complicated by toxic epidermal necrolysis), and acute haemolytic anaemia (1 case).

The clinical and pathological findings of Babesia infection in 32 dogs in northern Australia are presented. Eleven different breed types were represented from 6 localities in north Queensland and one locality in northern Western Australia. Twenty three (72%) were males. Babesia-infected dogs were grouped by the degree of haematological disturbance and clinical severity: Acute babesiosis (25/32), all pups with severe haemolytic anaemia; subclinical carriers (5/32) with non-specific malaise, characterised haematologically by a normal erythrogram but marked leucopenia; chronic anaemia, observed in 2 adult dogs. Pups were azotaemic (serum urea greater than 6.6 mmol/l) and had elevated serum bilirubin levels (20.8 to 48.5 mmol/l). Total serum protein was usually within the normal range. Pups that died were also hypoglycaemic and severely hyperkalaemic (K+ greater than 10 mmol/l). Low parasitaemias in routine blood smears complicated diagnosis but smears made from ear or toe capillaries, or after haematocrit concentration, greatly enhanced finding parasitised cells. At necropsy, pallor and jaundice were the most consistent observations. Haemoglobinuric nephrosis, an active reticulo-endothelial system and capillaries packed with large numbers of infected erythrocytes were the main histopathological findings. A combination of imidocarb dipropionate at 5 mg/kg body weight, given intramuscularly, with fluid therapy and blood transfusion was the most successful treatment.

A previously healthy 42-year-old woman developed severe dyspnea, chest discomfort, and malaise several hours after prolonged exposure to concentrated vapors from mineral spirits. On the way to the hospital, she sustained a cardiopulmonary arrest; on arrival several minutes later, she was found to be in ventricular fibrillation and was resuscitated. Her hospital course included slowly resolving cardiac abnormalities, amnesia, noncardiogenic pulmonary edema, abrupt hemolytic anemia, sustained rhabdomyolysis, and other metabolic abnormalities. It is highly probable that this syndrome represented acute and near-lethal toxicity caused by the inhalational exposure to the petroleum distillate known as mineral spirits. It is important that physicians be aware of this syndrome in order to recognize it on presentation and to warn patients of the risk of such toxic exposure.

Five cases of haemolytic anaemia occurring in male Nigerians following the ingestion of spiced barbecued meat (suya) are described. Although suya is a popular food item in various parts of Nigeria, all five patients described in this report had consumed a special brand, called red suya, purchased from vendors at a popular road junction between the cities of Lagos and Ibadan. Ingestion of the culprit suya sample was followed within 24 h by malaise and fever, while passage of dark-coloured urine and jaundice followed 1-3 days thereafter. Glucose-6-phosphate dehydrogenase (G6PD) deficiency was demonstrated by a fluorescent screening test in all cases, while the enzyme phenotype was shown to be GdA- in all four cases studied by starch-gel electrophoresis, thus suggesting that G6PD deficiency was a predisposing factor in the cases reported in this series. The haemolytic disease was self-limiting and full recovery followed in all cases. In view of the markedly circumscribed range from where the patients originated, the culprit agent responsible for the haemolytic disease is believed to be a recently introduced food additive that is probably accessible only to a limited number of suya vendors.

Healthy adult volunteers were inoculated intranasally with human parvovirus obtained from an asymptomatic blood donor. One week after inoculation, intense viremia was observed in seronegative volunteers, accompanied by a mild illness with pyrexia, malaise, myalgia, itching, and excretion of virus from the respiratory tract. In the following week hematologic studies revealed reticulocytopenia with an associated slight drop in hemoglobin concentration, lymphopenia, neutropenia, and a drop in platelet counts. At 17-18 days after inoculation a second-phase illness with rash and arthralgia lasting three to four days occurred in three of four infected volunteers. This study confirms the etiologic role of human parvovirus in erythematous rash illness, with the second-phase illness being consistent with adult cases of erythema infectiosum. Moreover, the hematologic changes associated with infection support the hypothesis that the same virus is responsible for the temporary arrest of erythropoiesis that leads to aplastic crisis in persons with chronic hemolytic anemia.

A 75 year old man, treated with ajmaline, was admitted with malaise, fever, acute renal failure and cholestatic jaundice. Haemolytic anaemia and thrombocytopaenia were also found with a positive indirect Coomb's test in the presence of ajmaline. The immunological and haematological data are discussed in the light of previously published cases.

A hypersensitivity reaction to low-dose (50-mg), short-term dapsone administration developed in a 16-year-old girl. The reaction included fever, malaise, dermatitis, jaundice with hepatic dysfunction, lymphadenopathy, and hemolytic anemia. Physicians should be familiar with this "sulfone syndrome," an uncommon, potentially serious, side effect of dapsone therapy.

A 2 year old girl presented with fever, malaise, a maculopapular rash and lymphadenopathy followed by the onset of haemolytic anaemia and massive splenomegaly. Serology was consistent with acquired toxoplasmosis. A 6 week course of pyrimethamine resulted in a rise in the haemoglobin and reduction of the splenomegaly. During the subsequent 10 years, pyrimethamine treatment of three similar acute episodes resulted in similar clinical responses. There was no spontaneous improvement in the haemolytic anaemia or splenomegaly when pyrimethamine was initially withheld for 6, 1, and 1.5 months respectively during three of these episodes. Investigations did not reveal an immunodeficiency state. This case suggests the possibility of a previously unreported causal association between acquired toxoplasmosis and haemolytic anaemia in a child.

Although Wilson's Disease is a treatable disorder, 9 of 15 cases referred with undiagnosed liver disease in the present series died in 3 to 53 days of admission. We have reviewed these cases to identify features that would allow earlier diagnosis and improvement in management. The presenting symptoms were lethargy and malaise (11 cases), jaundice (11), abdominal pain (9), and deteriorating school performance (4). At diagnosis, all fatal cases had jaundice and ascites, while only one of the 6 survivors had ascites and two had jaundice. Evidence of hemolysis was found in 3 fatal cases and 5 survivors. Serum bilirubin concentrations, aspartate transaminase, and prolongation of prothrombin time were significantly more abnormal in the fatal cases (p less than 0.01) as compared with the survivors. Cirrhosis was present in all fatal cases and in 2 of the 6 survivors. Wilson's Disease must be excluded in children presenting with frank liver disease as well as those with hemolytic anemia, persisting lethargy, abdominal pain, or deteriorating school performance.

Four cases of primary splenic hemangiosarcoma are described. The most common presenting symptoms were recurrent, fever, malaise, and abdominal pain. Three patients also had complaints referable to the urinary tract. Severe hemolytic anemia with bizarre or fragmented red blood cells on peripheral smear was noted in three patients, in two cases, for more than 1 year before diagnosis. Two patients had been treated for mammary carcinoma with ionizing radiation 10 years before developing hemangiosarcoma of the spleen. One patient had multiple congenital hemangiomas present from birth, and is thought to have developed hemangiosarcoma in a previously existing benign hemangioma. None of our patients survived more than 7 months after the diagnosis of hemangiosarcoma. The importance of early detection and treatment of this tumor is discussed.
