Fatal Disseminated Paracoccidioidomycosis In A Two-year-old Child.

A two year-old female child was admitted at the Pediatric Intensive Care Unit in a septic shock associated with a lymphoproliferative syndrome, with history of fever, adynamia and weight loss during the last two months. On admission, the main clinical and laboratory manifestations were: pallor, jaundice, disseminated enlarged lymph nodes, hepatosplenomegaly, crusted warts on face, anemia, eosinophilia, thrombocytopenia, increased direct and indirect bilirubin, alkaline phosphatase, and gammaglutamyl transpeptidase. A parenteral administration of fluids, dobutamine and mechanical ventilation was started, without improvement of the clinical conditions. A direct examination of exsudate collected from cervical lymph node revealed numerous oval-to-around cells with multiple budding, like a pilot wheel cell, suggesting Paracoccidioides brasiliensis. Even though treatment with intravenous sulfamethoxazole-trimethoprine was soon started, the child died 36 hours after hospital admission. Disseminated paracoccidioidomycosis was confirmed in the autopsy. This is the youngest case of paracoccidioidomycosis in children reported in the literature.4637-

Recurrent apparent life-threatening event as the first manifestation of congenital myasthenia

OBJECTIVE: To alert pediatricians about the importance of a careful investigation on recurrent apparent life-threatening events. Reports of the association of these events with congenital myasthenic syndromes were not found. CASE DESCRIPTION: A seven-month-old infant with recurrent apparent life-threatening events was admitted for investigation. During hospital stay, she presented cyanosis and respiratory failure, requiring mechanical ventilation for three days. After clinical improvement, hypotheses of gastroesophageal reflux and pulmonary aspiration were ruled out. The presence of eyelid ptosis, general hypotonia and weak crying led to the suspicion of congenital myasthenia, which was confirmed. Treatment with oral piridostigmine led to neurological and nutritional normalization, without any other apparent life-threatening event during the next three years. COMMENTS: The careful etiological investigation of apparent life-threatening events may lead to rare diagnosis that requires specific treatments, such as congenital myasthenia.OBJETIVO: Alertar os pediatras sobre a necessidade de investigar criteriosamente a etiologia de eventos com aparente risco de morte recorrente. Não foram encontrados relatos associando tais eventos à miastenia congênita. DESCRIÇÃO DO CASO: Lactente de sete meses apresentando história de eventos com aparente risco de morte recorrente foi internado para investigação. Durante a internação, apresentou cianose e dispneia progressiva, com necessidade de ventilação mecânica por três dias. Após a melhora clínica, e tendo sido descartadas as hipóteses de doença do refluxo gastroesofágico e aspiração pulmonar como desencadeantes, notou-se ptose palpebral bilateral, hipotonia apendicular e choro fraco, que conduziram à suspeita clínica de miastenia congênita. Após confirmação do diagnóstico, foi mantido tratamento ambulatorial com piridostigmina, com recuperação nutricional e neurológica, sem novos eventos com aparente risco de morte nos três anos seguintes. COMENTÁRIOS: A investigação minuciosa das causas de eventos com aparente risco de morte pode levar a diagnósticos menos frequentes que exigem tratamento específico, como a miastenia congênita.OBJETIVO: Alertar a los pediatras sobre la necesidad de investigar criteriosamente la etiología de eventos con aparente riesgo de muerte recurrente. No se encontraron relatos asociando tales eventos a la miastenia congénita. DESCRIPCIÓN DEL CASO: Lactante de siete meses presentando historia de eventos con aparente riesgo de muerte recurrente fue internado para investigación. Durante la internación, presentó cianosis y disnea progresiva, con necesidad de ventilación mecánica por tres días. Después de la mejora clínica, y habiendo sido rechazadas las hipótesis de enfermedad del reflujo gastroesofágico y aspiración pulmonar como desencadenantes, se notó ptosis palpebral bilateral, hipotonía apendicular y lloro débil, que condujeron a la sospecha clínica de miastenia congénita. Después de la confirmación del diagnóstico, se mantuvo el tratamiento ambulatorial con piridostigmina, con recuperación nutricional y neurológica, sin nuevos eventos con aparente riesgo de muerte en los tres años siguientes. COMENTARIOS: La investigación minuciosa de las causas de eventos con aparente riesgo de muerte puede llevar a diagnósticos menos frecuentes que exigen tratamiento específico, como la miastenia congénita.12112

Infective Endocarditis Due To Haemophilus Aphrophilus: A Case Report.

To report the case of a child with infective endocarditis caused by Haemophilus aphrophilus. Boy with 20 days of fever and chills. On admission, he was febrile, pale and with no signs of hemodynamic instability; on cardiac auscultation, a mitral-related holosystolic murmur was observed. Laboratory examination identified anemia (hemoglobin = 9.14 g/dL), total leukocytes of 11,920 mm3, platelets of 250,000 mm3, elevated sedimentation velocity of red cells and elevated C-reactive protein. The echocardiogram revealed image on mitral valve, resembling vegetation. Considering endocarditis, antibiotic therapy was started with crystalline penicillin (200,000 UI/kg/day) in association with gentamicin (4 mg/kg/day). On the third day of treatment, Haemophilus aphrophilus was identified in the blood cultures and the antibiotic scheme was replaced with ceftriaxone (100 mg/kg/day). On the 20th day of evolution, the patient was pale but with no fever or other complaints. Examinations showed hemoglobin = 7.0 g/dL, leukocytes = 2,190 mm3, platelets = 98,000 mm3, international normalized ratio = 1.95 and R = 1.89. Considering the hypothesis of adverse reaction to ceftriaxone, a 6-week replacement treatment with ciprofloxacin (20 mg/kg/day) was started. Examination results normalized after 72 hours of the replacement therapy. During ambulatory follow-up, patient presented with severe mitral regurgitation, undergoing a valve replacement with a metallic prosthetic valve 9 months after acute event. Patient has done well throughout the 3-year ambulatory follow-up. Identification of agents of the HACEK group (Haemophilus ssp, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens and Kingella kingae) in children with infective endocarditis is rare. This case report, with no HACEK agent-related risk factors, reinforces the need for identification of the etiological agent of endocarditis to ensure adequate treatment.84178-8

DESCRIÇÃO: Menino com febre e calafrios há 20 dias. À internação, apresentava-se febril, descorado e sem sinais de instabilidade hemodinâmica; à ausculta cardíaca, tinha sopro holosistólico em foco mitral. Os exames laboratoriais identificaram anemia (hemoglobina = 9,14 g/dL), leucócitos totais de 11.920 mm³, plaquetas de 250.000 mm³, velocidade de sedimentação das hemácias e proteína C reativa elevadas. O ecocardiograma revelou imagem em válvula mitral, sugestiva de vegetação. Com a hipótese de endocardite, foi iniciada antibioticoterapia com penicilina cristalina (200.000 UI/kg/dia) associada à gentamicina (4 mg/kg/dia). No terceiro dia de tratamento, foi identificado Haemophilus aphrophilus em hemoculturas, sendo então trocado o esquema antibiótico para ceftriaxona (100 mg/kg/dia). No 20º dia de internação, encontrava-se pálido, mas sem febre e sem outras queixas. Os exames mostravam hemoglobina = 7,0 g/dL, leucócitos = 2.190 mm³, plaquetas = 98.000 mm³, razão normatizada internacional = 1,95 e R = 1,89. Foi feita hipótese de reação adversa ao ceftriaxona, que foi substituído por ciprofloxacina, 20 mg/kg/dia, até completar 6 semanas de tratamento. Após 72 horas da troca, houve normalização dos exames. Durante seguimento ambulatorial, apresentou insuficiência mitral grave, sendo submetido a troca de válvula por prótese metálica 9 meses após quadro agudo. Há 3 anos encontra-se bem, em acompanhamento ambulatorial. COMENTÁRIOS: É rara a identificação de agentes do grupo HACEK (Haemophilus ssp, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens e Kingella kingae) em crianças com endocardite infecciosa. O caso apresentado, sem fatores de risco relacionados a esses agentes, reafirma a necessidade de tentar sempre identificar o agente etiológico das endocardites para adequação do tratamento.17818

Dapsone Hypersensitivity Syndrome In An Adolescent During Treatment During Of Leprosy.

A 12 y old girl was admitted 24 days after start a WHO multidrug therapy scheme for multibacillary leprosy (dapsone, clofazimine and rifampicin) with intense jaundice, generalized lymphadenopathy, hepatoesplenomegaly, oral erosions, conjunctivitis, morbiliform rash and edema of face, ankles and hands. The main laboratory data on admission included: hemoglobin, 8.4 g/dL; WBC, 15,710 cells/mm3; platelet count, 100,000 cells/mm3; INR = 1.49; increased serum levels of aspartate and alanine aminotransferases, gamma-glutamyl transpeptidase, alkaline phosphatase, direct and indirect bilirubin. Following, the clinical conditions had deteriorated, developing exfoliative dermatitis, shock, generalized edema, acute renal and hepatic failure, pancytopenia, intestinal bleeding, pneumonia, urinary tract infection and bacteremia, needing adrenergic drugs, replacement of fluids and blood product components, and antibiotics. Ten days after admission she started to improve, and was discharged to home at day 39th, after start new supervised treatment for leprosy with clofazimine and rifampicin, without adverse effects. This presentation fulfils the criteria for the diagnosis of dapsone hypersensitivity syndrome (fever, generalized lymphadenopathy, exfoliative rash, anemia and liver involvement with mixed hepatocellular and cholestatic features). Physicians, mainly in geographical areas with high prevalence rates of leprosy, should be aware to this severe, and probably not so rare, hypersensitivity reaction to dapsone.46331-

Physicians, mainly in geographical areas with high prevalence rates of leprosy, should be aware to this severe, and probably not so rare, hypersensitivity reaction to dapsone.Menina, 12 anos, foi admitida referindo o uso de esquema de poliquimioterapia preconizado pela OMS para tratamento de hanseníase forma multicibacilar (dapsona, rifampicina e clofazimina) há 24 dias, apresentando icterícia, linfadenomegalia generalizada, hepatoesplenomegalia, conjuntivite, úlceras orais, exantema morbiliforme e edema de face, mãos e tornozelo. Os principais achados laboratoriais à admissão incluíam: hemoglobina, 8,4 g/dl; leucograma, 15.710 céls/mm³; contagem de plaquetas, 100.000 céls/mm³; RNI = 1,49; aumento dos níveis séricos da alanino e aspartato aminotransferases, gama-glutamil transpeptidase, fosfatase alcalina e bilirrubinas. Em seqüência, ocorreu piora do quadro, desenvolvendo dermatite esfoliativa, choque, edema generalizado, insuficiências renal e hepática, pancitopenia, sangramento intestinal, pneumonia, infecção urinária e bacteremia, necessitando de drogas adrenérgicas, antibióticos, infusão de líquidos e hemoderivados. Iniciou melhora no 10º dia de internação, recebendo alta hospitalar no 39º dia, tendo iniciado novo tratamento supervisionado para hanseníase com rifampicina e clofazimina, sem efeitos adversos. O caso relatado preenche os critérios para o diagnóstico de síndrome de hipersensibilidade à dapsona (febre, dermatite esfoliativa, linfadenopatia, anemia e acometimento hepático com necrose hepatocítica e colestase). Os médicos, principalmente em regiões com alta prevalência de hanseníase, devem estar atentos para esta grave, e provavelmente não tão rara, reação de hipersensibilidade à dapsona
