Seventy-three consecutive cases of childhood acute lymphoblastic leukemia (ALL) diagnosed and managed in Queen Mary Hospital over a 10-year period from 1985 to 1994 were retrospectively analysed for their presenting features and treatment outcome. The 48 boys and 25 girls ranged in age from 0.4 to 14.2 years (median: 4.3 years). Bone and joint pain was a relatively common presenting feature besides fever, hepatosplenomegaly and lymphadenopathy. Immunophenotyping of blast cells showed: 51 B-cell precursor ALL, one B-ALL, 10 T-ALL and three myeloid-antigen positive ALL. Eight cases were unclassified since immunophenotyping had not been performed. Out of the 73 patients, treatment outcome was analysed in 20 cases treated with UKALL-VIII regimen and 28 cases treated with either the UKALL-XI regimen or the Hong Kong Children Cancer Study Group (HKCCSG) protocol which was modelled upon UKALL-XI. Although complete remission rates were similar between the two groups, patients treated with the former regimen that was less intensified suffered more relapses than the latter (56 per cent versus 21 per cent, P = 0.04). There were, however, no significant differences both in event-free survival (38.2 +/- 11.2 per cent versus 71.3 +/- 9.3 per cent, P = 0.12) and overall survival (70.0 +/- 10.2 per cent versus 79.6 +/- 8.3 per cent, P = 0.41) between the two groups at 3 years by long-rank test. With the use of risk-directed therapy and improved supportive care, two-thirds of our patients are able to enjoy long-term event-free survival.

We report the case of a 50-year-old man with a 4-year history of high spiking fever accompanied by a widespread, urticarial, non-pruritic or only sometimes mildly pruritic eruption and arthralgia. He also had generalized lymphadenopathy, hepatosplenomegaly, and hyperosteoses of the lower lumbar spine. Laboratory examination revealed an elevated erythrocyte sedimentation rate, elevated white blood cell and platelet counts, hypoalbuminemia, and elevated serum IgM with IgM kappa monoclonal immunoglobulin. We diagnosed his condition as Schnitzler's syndrome, in contrast to the diagnosis of adult onset Still's disease, for which he had been initially followed up by his internist. We compare clinical and histopathological findings for both diseases and, as this patient meets two of the six existing diagnostic criteria for adult onset Still's disease, we propose that Schnitzler's syndrome is an important entity to be added to the list of differential diagnoses for adult onset Still's disease.

We report 28 patients (20 male) with a syndrome characterized by abrupt onset of fever, malaise, aphthous stomatitis, tonsillitis, pharyngitis, and cervical adenopathy (PFAPA syndrome). Episodes of fever occurred at intervals of 5.1 +/- 1.3 weeks beginning at the age of 4.2 +/- 2.7 years. Fever, malaise, tonsillitis with negative throat cultures, and cervical adenopathy were reported in all 28 patients, aphthae in 19, headache in 5, abdominal pain in 5, and arthralgia in 3. Mild hepatosplenomegaly was observed in 6 patients. Mild leukocytosis, elevation of the erythrocyte sedimentation rate, and fibrinogen were found during attacks. These episodes of illness resolved spontaneously in 4.3 +/- 1.7 days. Serum IgD was found elevated (>100 U/mL) in 12 of the 18 patients tested (140.2 +/- 62.4 U/mL). Affected children grow normally, have no associated diseases, and have no long-term sequelae. Attacks were aborted by a single dose of oral prednisone (2 mg/kg) at the beginning of the attack in all 15 patients in whom this medication was prescribed. In 9 patients the syndrome has completely resolved (beginning at the age of 2.9 +/- 1.3 and lasting 8 +/- 2.5 years). In 3 other patients complete resolution of the attacks occurred after tonsillectomy was performed. PFAPA is sporadic, and no ethnic predilection was found. Increased awareness of the clinical syndrome has resulted in more frequent diagnosis and adequate treatment.

We report three children with tubulointerstitial renal failure following leptospirosis. All had acute nonoliguric renal failure with mild hypocalemia and mild metabolic acidosis. Maximum blood urea nitrogen (BUN) and creatinine were 217 and 7.1 mg/dl, respectively, on the 6th day of disease, and no patient required dialysis. They presented with acute febrile illness and dehydration, and required intravenous fluid supplements. Myalgia, vomiting, and bleeding were found in two children. Abdominal pain, arthralgia, diarrhea, and conjunctival suffusion were found in one child. Only one child, who had an underlying disease of beta-thalassemia/Hb E, had jaundice, hepatosplenomegaly, anemia, and thrombocytopenia. Penicillin treatment was given in one case. All recovered, with normal renal function. The leptospirosis complement fixation test was used to confirm diagnosis. L. batavia was considered the etiologic agent in two of the children.

In this article, we report the case of a 16-month-old German boy who was admitted to the Children's Hospital of Stuttgart with a 4-week history of intermittent fever, decreased appetite, weakness, fatigue, and difficulty sleeping. He was healthy at birth and remained so for the first 15 months of his life. On admission, physical examination showed enlarged cervical, axillary, and inguinal lymph nodes, as well as hepatosplenomegaly. Laboratory data revealed pancytopenia, elevated liver function tests, and hypergammaglobulinemia. Blood, stool, and urine culture results were negative. Viral infections and rheumatologic and autoimmune disorders were ruled out, but a positive titer for Leishmania antibodies was noted. In a liver and bone marrow biopsy, the amastigote form of the parasite could not be seen in cells. The promastigote form of Leishmania was found and the diagnosis of visceral leishmaniasis was made by combining the cultures of both the liver and the bone marrow biopsy material in 5 mL 0.9% saline on brain heart infusion agar, supplemented with defibrinated rabbit blood and incubated at 25 to 26 degrees C for 5 days. The parasite was identified by Southern blot analysis as Leishmania infantum. Specific therapy with the antimonial compound sodium stibogluconate with a dose of 20 mg/kg body weight was begun immediately. Within 4 days, the patient became afebrile. The side effects of treatment, including erosive gastritis, cholelithiasis, worsening hepatosplenomegaly, elevation of liver enzymes, pancreatitis, and electrocardiogram abnormalities, necessitated the discontinuation of treatment after 17 days. On discharge 4 weeks later, the patient was stabilized and afebrile with a normal spleen, normal complete blood count, normal gammaglobulins, and decreasing antibody titers to Leishmania. During the next 24 months, the patient experienced intermittent episodes of abdominal pain, decreased appetite, recurrent arthralgia, and myalgia. But at his last examination in January 1998, he was well; all symptoms mentioned above had disappeared. Because the child had never left Germany, nonvector transmission was suspected and household contacts were examined. His mother was the only one who had a positive antibody titer against Leishmania donovani complex. She had traveled several times to endemic Mediterranean areas (Portugal, Malta, and Corse) before giving birth to the boy. But she had never been symptomatic for visceral leishmaniasis. Her bone marrow, spleen, and liver biopsy results were within normal limits. Culture results and polymerase chain reaction of this material were negative. A Montenegro skin test result was positive, indicating a previous infection with Leishmania. Western blot analysis showed specific recognition by maternal antibodies of antigens of Leishmania cultured from the boy's tissue. Visceral leishmaniasis is endemic to several tropical and subtropical countries, but also to the Mediterranean region. It is transmitted by the sand fly (Phlebotomus, Lutzomyia). Occasional nonvector transmissions also have been reported through blood transfusions, sexual intercourse, organ transplants, excrements of dogs, and sporadically outside endemic areas. Only 8 cases of congenital acquired disease have been described before 1995, when our case occurred. In our patient, additional evaluation showed that the asymptomatic mother must have had a subclinical infection with Leishmania that was reactivated by pregnancy, and then congenitally transmitted to the child. Visceral leishmaniasis has to be considered in children with fever, pancytopenia, and splenomegaly, even if the child has not been to an endemic area and even if there is no evidence of the disease in his environment, because leishmaniasis can be transmitted congenitally from an asymptomatic mother to her child.

Dutch type periodic fever (DPF) is an autosomal recessive hereditary fever syndrome. Cases have been reported worldwide, the majority from France and The Netherlands. From infancy the patients suffer fever attacks that recur every 2-8 weeks, often precipitated by immunizations, infections or emotional stress. Fever lasts 2-7 days and can be accompanied by malaise, headache, diarrhea, abdominal pain, vomiting, skin rashes, arthralgia, arthritis, tender lymphadenopathy, hepatosplenomegaly, and oral and genital ulcers. Laboratory evaluation during fever shows granulocytosis and elevated acute phase reactants. DPF is caused by a deficiency of the enzyme mevalonate kinase (MK). Besides DPF, the spectrum of MK deficiency includes a severe phenotype, mevalonic aciduria (MA). MA patients have less residual MK activity, leading to substantially higher urinary mevalonic acid excretion than in DPF. Mevalonic aciduria is characterized by mental retardation and dysmorphic features in addition to the clinical features of DPF. At the genomic level, several mutations of varying severity have been identified. The DPF phenotype is caused by one particular mild missense mutation. Most patients are compound heterozygotes for this mutation and a more severe mutation. The mechanism by which MK deficiency leads to fever is not understood. The vast majority of DPF patients have persistently elevated serum IgD and can be classified as having hyperimmunoglobulinemia D and periodic fever syndrome (HIDS). Conversely, most HIDS patients have MK deficiency and hence DPF, but the two disorders do not overlap entirely.

Adult-onset Still's disease (AOSD) is a rare disorder of unknown aetiology, characterised by high spiking fever, an evanescent, erythematous, maculopapular rash, arthralgia or arthritis, lymphadenopathy, hepatosplenomegaly, sore throat and serositis. It is associated with marked leukocytosis, high erythrocyte sedimentation rate, increased level of serum ferritin and negative rheumatoid factor and antinuclear antibody tests. Here we report a patient in whom an urticaria-like rash was an uncommon presenting clinical feature of AOSD. To our knowledge, this association has only been reported once before.

Thrombocytopenic purpura associated with brucellosis has rarely been described in children. The thrombocytopenic purpura is usually part of the array of manifestations of brucellosis, such as fever, malaise, arthralgia, arthritis, hepatosplenomegaly and lymphadenopathy. We describe a 4-year-old girl in whom severe thrombocytopenic purpura was the only manifestation of brucellosis and resolved after appropriate antibiotic therapy. We conclude that brucellosis should be included in the differential diagnosis of thrombocytopenic purpura in areas endemic for brucellosis, and when there is a history of exposure to infected food products.

We describe a 21-year old man who was diagnosed as having adult onset Still's disease (AOSD) in association with isotretinoin treatment for acne conglobata. The patient was febrile, with a macular salmon pink rash, arthritis, hepatosplenomegaly, and axial lymphadenopathy. Laboratory results showed leukocytosis, mild liver dysfunction and negative rheumatoid factor and antinuclear antibodies. Isotretinoin, an orally active derivative of vitamin A, has been associated with various rheumatologic conditions such as arthralgia, myalgia, vasculitis and arthritis. The etiology of rheumatic disorders associated with retinoids is still obscure; however, it is presumed that immunomodulation by several mechanisms (such as an alteration of the cytokine balance) is probably ascribable to this interesting association.

This is a case report of a 29 year old male with pneumocystis pneumonia and tuberculosis, and who was initially suspected of having HIV infection, based on risk factor analyses, but was subsequently shown to be HIV negative. The patient arrived at the hospital with fever, cough, weight loss, loss of appetite, pallor, and arthralgia. In addition, he was jaundiced and had cervical lymphadenopathy and mild heptosplenomegaly. He had interstitial infiltrates of the lung, sputum smears positive for Mycobacterium tuberculosis and Pneumocystis carinii, and stool tests were positive for Strongyloides stercoralis and Schistosoma mansoni. He was diagnosed as having AIDS, and was treated for tuberculosis, pneumocystosis, and strongyloidiasis with a good response. The patient did not receive anti-retroviral therapy, pending outcome of the HIV tests. A month later, he was re-examined and found to have worsening hepatosplenomegaly, pancytopenia, fever, and continued weight loss. At this time, it was determined that his HIV ELISA antibody tests were negative. A bone marrow aspirate was done and revealed amastigotes of leishmania, and a bone marrow culture was positive for Leishmania species. He was treated with pentavalent antimony, 20 mg daily for 20 days, with complete remission of symptoms and weight gain. This case demonstrates that immunosuppression from leishmaniasis and tuberculosis may lead to pneumocystosis, and be misdiagnosed as HIV infection. The occurrence of opportunistic infections in severely ill patients without HIV must always be considered and alternate causes of immunosuppression sought.
