Acute-subacute paracoccidioidomycosis: A paediatric cohort of 141 patients, exploring clinical characteristics, laboratorial analysis and developing a non-survival predictor.

The acute-subacute form of paracoccidioidomycosis (PCM) is a severe systemic mycosis that affects children and adolescents from endemic regions, leading to generalised lymphadenopathy, fever, weight loss, anaemia, eosinophilia, hypoalbuminemia and hypergammaglobulinemia. The objective of this study is to describe the clinical and laboratorial characteristics of acute-subacute PCM, to determine a mortality risk factor and to propose a test for non-survival hazard related to the disease. Children and adolescents diagnosed with PCM, under 15 years were included in the study. Their epidemiological, clinical and laboratorial data were obtained from the hospital records. Descriptive analysis, comparison of means, univariate logistic regression, multivariate logistic regression and a ROC curve were performed in order to identify significant information (P < .05). Through a period of 38 years, 141 children and adolescents were diagnosed with acute-subacute PCM. The main antifungal agent used for the treatment was sulfamethoxazole-trimethoprim (SMX-TMP). The complication rate was 17%, the relapse rate was 7.8% and the mortality rate was 5.7%. A low albumin dosage was identified as a predictor factor for mortality. The cut-off for serum albumin was 2.18 g/dL, above which, the survival rate is 99.1%. Thus, simple clinical and laboratorial examinations may lead to the diagnosis of acute-subacute PCM, and the beginning of the treatment is encouraged even before the isolation of the fungus in biological samples, preventing unfavourable outcomes. Patients with an albumin dosage ≤ 2.18g/dL must receive special attention, preferably hospitalised, during the first four weeks of treatment for presenting an elevated mortality hazard.

Invasive non-type b haemophilus influenzae disease: report of eight cases / Doença invasiva causada por haemophilus influenzae não tipo b: relato de oito casos

ASTRACT Objective: To describe eight cases of invasive non-type b Haemophilus influenzae disease in children admitted to Hospital de Clínicas of Universidade Estadual de Campinas. Cases description: In 2015, there were eight cases of invasive non-type b H. influenzae disease. We tested the ampicillin sensitivity and beta-lactamase production of the strains identified and performed the genotyping. Molecular typing was determined by Pulsed-Field Gel Electrophoresis. Four patients were diagnosed with bacteremia; in two cases, H. influenzae was detected in the pleural fluid, and two patients had meningitis. Patients with comorbidities represented 37.5% of cases. Except for the strain of one patient - not sent to the reference laboratory -, all were ampicillin-sensitive and non-beta-lactamase-producing. Genotyping identified four non-capsular, one type c, and two type a strains. Molecular typing ruled out nosocomial transmission since all serotypes were distinct regarding genotype. Comments: The rise in cases of invasive non-type b H. influenzae infection was real. There was no nosocomial transmission, and we found no justification for the increase. These data indicate the need for surveillance to correctly diagnose, monitor, and understand the spectrum of non-type b H. influenzae disease.

ABSTRACT Objetivo: Descrever oito casos de doença invasiva por Haemophilus influenzae não tipo b em crianças internadas no Hospital de Clínicas da Universidade Estadual de Campinas. Descrição dos casos: Em 2015, ocorreram oito casos de doença invasiva por H. influenzae não tipo b. Nas cepas identificadas, testou-se a sensibilidade à ampicilina e a produção de betalactamase, e realizou-se a genotipagem. A tipagem molecular foi feita por Pulsed Field Gel Electrophoresis. Em quatro pacientes, o diagnóstico foi de bacteremia; em dois casos, H. influenzae foi identificado em líquido pleural, e dois pacientes tiveram meningite. Comorbidades foram encontradas em 37,5% dos pacientes. Com exceção da cepa de um dos pacientes (que não foi enviada ao laboratório de referência), todas eram sensíveis à ampicilina e não produtoras de betalactamase. A genotipagem identificou quatro cepas não capsulares, uma cepa tipo c e duas cepas tipo a. A tipagem molecular descartou a transmissão intra-hospitalar, já que todos os sorotipos eram distintos quanto ao genótipo. Comentários: O aumento dos casos de infecção invasiva por H. influenzae não tipo b foi real. Não houve transmissão intra-hospitalar e não foi encontrada justificativa para o aumento. Esses dados indicam a necessidade de vigilância para diagnosticar corretamente, monitorar e entender o espectro da doença causada por H. influenzae não tipo b.

Septic arthritis caused by Salmonella enterica serotype Rubislaw: A case report.

An eleven-year-old boy presented with fever and hip pain, with limited mobility of the right side of the hip. Computed tomography scan revealed an increased volume of the right coxo-femoral joint, requiring surgical drainage of purulent secretion, from which Salmonella enterica was isolated. After four weeks of treatment with third-generation cephalosporin, he was discharged with a favorable evolution. Invasive disease caused by Salmonella spp represents a small proportion of salmonellosis cases, although it is responsible for greater rates of hospitalization, morbidity and mortality. Children under 5 years, elders over 60 years and immunodeficient patients have greater risk for invasive salmonellosis.

Diagnóstico tardio de sífilis congênita: uma realidade na atenção à saúde da mulher e da criança no brasil / Late diagnosis of congenital syphilis: a recurring reality in women and children health care in brazil

RESUMO Objetivo: Descrever um caso de sífilis congênita com diagnóstico tardio e identificar as oportunidades perdidas nas diversas fases/níveis da atenção à saúde, que retardaram a realização do diagnóstico. Descrição do caso: Menino, 34 dias de vida, encaminhado da Unidade Básica de Saúde a um hospital terciário por apresentar aumento do volume abdominal e icterícia progressiva há 2 semanas, hipocolia fecal, hepatoesplenomegalia, anemia, plaquetopenia e elevação de enzimas hepáticas. Ao exame físico, apresentava lesões eritemato-descamativas nas mãos e nos pés e exantema macular em região inguinal, presença de ascite, fígado palpável a 5 cm do rebordo costal direito e baço palpável a 3 cm do rebordo costal esquerdo. Sorologia do lactente: CMIA (quimioluminescência de micropartículas) reagente, VDRL (Venereal Diseases Research Laboratory) 1:1024 e TPHA (Treponema pallidum Hemaglutination) reagente. Sorologia materna: CMIA e TPHA reagentes, VDRL 1:256. Radiografia de ossos longos mostrava periostite simétrica; levantamento periosteal; e bandas metafisárias lucentes em fêmures, úmeros, ulnas e tíbias. Após tratamento com penicilina cristalina, apresentou melhora clínica e laboratorial, recebendo alta no 18º dia de internação. Comentários: Este caso mostra que ainda ocorre diagnóstico tardio de sífilis congênita por falhas nas estratégias de prevenção dessa doença, tanto na atenção básica quanto nos níveis secundário e terciário. A aplicação das intervenções preconizadas pelo Ministério da Saúde e a identificação das situações em que ocorrem falhas na sua execução são importantes para a avaliação da assistência de rotina em todos os níveis de atenção e nas diversas unidades responsáveis pelo cuidado do recém-nascido e do lactente jovem.

ABSTRACT Objective: To describe a case of congenital syphilis with a late diagnosis and identify missed opportunities at diverse phases/levels of healthcare, which led to late diagnosis. Case description: Boy, 34 days of life, referred from a basic healthcare unit to a tertiary hospital due to enlarged abdominal volume and progressive jaundice for 2 weeks, fecal hypocholia, hepatosplenomegaly, anemia, low platelet count and elevated liver enzymes. At physical examination, the infant presented with erythematous-exfoliative lesions on the palms and soles, macular rash in the inguinal region, ascitis, palpable liver 5 cm below the right costal margin and a palpable spleen 3 cm from the left costal margin. Infant serology: reactive CMIA (chemiluminescent microparticle immunoassay), VDRL (Venereal Diseases Research Laboratory) 1:1024 and reactive TPHA (Treponema pallidum Hemagglutination). Maternal serology: reactive CMIA and TPHA, VDRL 1:256. Radiography of the long bones showed symmetric periostitis, periosteal thickening, and lucent bands in the femur, humerus, ulna and tibia. After treatment with crystalline penicillin, the infant showed clinical and laboratory improvement, receiving hospital discharge at the 18th hospitalization day. Comments: This case shows that congenital syphilis is occasionally diagnosed late as a result of failed strategies to prevent this disease, both in the basic and secondary/tertiary levels of care. The application of interventions recommended by the Ministry of Health and identification of the situation in which there is ineffective implementation of these measures are important to assess routine care in all levels of healthcare and diverse units responsible for newborn and infant health care.

Association between single nucleotide polymorphisms in TLR4, TLR2, TLR9, VDR, NOS2 and CCL5 genes with acute viral bronchiolitis.

BACKGROUND: Acute viral bronchiolitis is the leading cause of hospitalization among infants during the first year of life. Most infants hospitalized for bronchiolitis do not present risk factors and are otherwise healthy. Our objective was to determine the genetic features associated with the risk and a severe course of bronchiolitis. METHODS: We prospectively evaluated 181 infants with severe bronchiolitis admitted at three hospitals over a 2-year period, who required oxygen therapy. The control group consisted of 536 healthy adults. Patients were evaluated for the presence of comorbidities (premature birth, chronic respiratory disease, and congenital heart disease), underwent nasopharyngeal aspirate testing for virus detection by multiplex-PCR, and SNPs identification in immune response genes. Patient outcomes were assessed. RESULTS: We observed association between SNP rs2107538*CCL5 and bronchiolitis caused by respiratory syncytial virus(RSV) and RSV-subtype-A, and between rs1060826*NOS2 and bronchiolitis caused by rhinovirus. SNPs rs4986790*TLR4, rs1898830*TLR2, and rs2228570*VDR were associated with progression to death. SNP rs7656411*TLR2 was associated with length of oxygen use; SNPs rs352162*TLR9, rs187084*TLR9, and rs2280788*CCL5 were associated with requirement for intensive care unit admission; while SNPs rs1927911*TLR4, rs352162*TLR9, and rs2107538*CCL5 were associated with the need for mechanical ventilation. CONCLUSIONS: Our findings provide some evidence that SNPs in CCL5 and NOS2 are associated with presence of bronchiolitis and SNPs in TLR4, TLR2, TLR9, VDR and CCL5 are associated with severity of bronchiolitis.

TUBERCULOSIS IN PEDIATRIC PATIENTS: HOW HAS THE DIAGNOSIS BEEN MADE? / TUBERCULOSE EM PACIENTES PEDIÁTRICOS: COMO TEM SIDO FEITO O DIAGNÓSTICO?

OBJECTIVE: To describe clinical, radiological, epidemiological, and microbiological characteristics of pediatric patients with diagnosis of tuberculosis in a period of 15 years. METHODS: Retrospective study including children and adolescents younger than 18 years diagnosed with tuberculosis in the Clinical Hospital of the Universidade Estadual de Campinas in São Paulo State, Brazil. Active tuberculosis was defined by the identification of Mycobacterium tuberculosis in culture, microscopy, or histopathological examination. Children with positive clinical history and radiological tests who had been exposed to sick adults or with positive tuberculin skin test were also considered as having active tuberculosis. Statistical analysis compared the data obtained from children younger and older than 10 years of age, since they present a disease pattern more similar to adults. RESULTS: There were 145 identified cases, 61.4% in patients under 10 years of age. The main symptoms reported were coughing (55.9%) and fever (46.9%), and the variables of fever, coughing, weight-loss, and pain were significantly influenced by age, with a higher frequency in older children. Diagnosis was confirmed by culture, microscopy, or histopathology in 67.6% of the cases. The other cases (32.4%) had the diagnosis of tuberculosis based on clinical, radiological, and epidemiological characteristics, as well as tuberculin skin test. The positivity for culture, microscopy, and tuberculin skin test was, respectively, 65.8, 35.7, and 72.3%. History of contact with a sick adult was confirmed in 37.2%, without influence of age. CONCLUSIONS: Diagnosis of tuberculosis in children is still a challenge, since all the confirmation tests have low positivity. These results demonstrate the need for new diagnostic methods and improved strategies for searching sick contacts.

OBJETIVO: Descrever o quadro clínico, radiológico e o perfil epidemiológico e microbiológico de pacientes diagnosticados com tuberculose em um período de 15 anos. MÉTODOS: Estudo retrospectivo de crianças e adolescentes menores de 18 anos diagnosticados com tuberculose no Hospital de Clínicas da Universidade Estadual de Campinas. Tuberculose ativa foi definida pela identificação de M. tuberculosis em cultura, baciloscopia ou exame histopatológico ou, ainda, casos com quadro clínico e radiológico compatível e com história de exposição à tuberculose ou com teste tuberculínico positivo. Foi realizada análise estatística, com comparação entre os dados de crianças menores e maiores de 10 anos, já que estas apresentam doença com padrão mais próximo do adulto. RESULTADOS: Foram identificados 145 casos, 61,4% em pacientes menores de 10 anos. Os principais sintomas relatados foram tosse (55,9%) e febre (46,9%), sendo que as variáveis febre, tosse, emagrecimento e dor se associaram à idade, estando mais presentes em crianças maiores de 10 anos. O diagnóstico foi confirmado (cultura, baciloscopia ou histopatológico) em 67,6% dos casos. Os demais (32,4%) tiveram seu diagnóstico realizado com base no quadro clínico, radiológico, epidemiológico e teste tuberculínico. A positividade da cultura, da baciloscopia e do teste tuberculínico foram, respectivamente, 65,8; 35,7 e 72,3%. História de contato com adulto tuberculoso foi confirmada em 37,2% dos casos. CONCLUSÕES: O diagnóstico de tuberculose em pediatria é complexo, considerando-se que todos os parâmetros usados têm baixa positividade. Os resultados apontam a necessidade de novos métodos diagnósticos e também de melhorias nas estratégias de busca de comunicantes.

Bilateral spontaneous chylothorax after severe vomiting in children / Quilotórax bilateral espontâneo após vômitos excessivos em criança

Abstract Objective: To report the case of a child with bilateral chylothorax due to infrequent etiology: thoracic duct injury after severe vomiting. Case description: Girl, 7 years old, with chronic facial swelling started after hyperemesis. During examination, she also presented with bilateral pleural effusion, with chylous fluid obtained during thoracentesis. After extensive clinical, laboratory, and radiological investigation of the chylothorax etiology, it was found to be secondary to thoracic duct injury by the increased intrathoracic pressure caused by the initial manifestation of vomiting, supported by lymphoscintigraphy findings. Comments: Except for the neonatal period, chylothorax is an infrequent finding of pleural effusion in children. There are various causes, including trauma, malignancy, infection, and inflammatory diseases; however, the etiology described in this study is poorly reported in the literature.

Resumo Objetivo: Relatar o caso de uma criança com quilotórax bilateral devido a etiologia pouco frequente: lesão do ducto torácico após quadro de vômitos excessivos. Descrição do caso: Menina, sete anos, apresentava edema facial crônico iniciado após quadro de hiperemese. À avaliação, também apresentava derrame pleural bilateral, com líquido quiloso obtido na toracocentese. Após extensa investigação clínica, laboratorial e radiológica da etiologia do quilotórax, foi definido ser secundário a lesão do ducto torácico por aumento da pressão intratorácica pela manifestação inicial de vômitos, corroborado por achados de linfocintilografia. Comentários: À exceção do período neonatal, o quilotórax é achado infrequente de efusão pleural em crianças. As causas são diversas, incluindo trauma, neoplasia, infecção e doenças inflamatórias; contudo, etiologia como a aqui descrita é pouco relatada na literatura.

Reexpansion pulmonary edema in children.

OBJECTIVE To present a case of a patient with clinical and radiological features of reexpansion pulmonary edema, a rare and potentially fatal disease. CASE DESCRIPTION An 11-year-old boy presenting fever, clinical signs and radiological features of large pleural effusion initially treated as a parapneumonic process. Due to clinical deterioration he underwent tube thoracostomy, with evacuation of 3,000 mL of fluid; he shortly presented acute respiratory insufficiency and needed mechanical ventilation. He had an atypical evolution (extubated twice with no satisfactory response). Computerized tomography findings matched those of reexpansion edema. He recovered satisfactorily after intensive care, and pleural tuberculosis was diagnosed afterwards. COMMENTS Despite its rareness in the pediatric population (only five case reports gathered), the knowledge of this pathology and its prevention is very important, due to high mortality rates. It is recommended, among other measures, slow evacuation of the pleural effusion, not removing more than 1,500 mL of fluid at once.

OBJETIVO Relatar caso de paciente con cuadro clínico y radiológico de edema pulmonar de reexpansión, patología rara y potencialmente fatal. DESCRIPCIÓN DEL CASO Niño de 11 años con fiebre y cuadro clínico-radiológico de derrame pleural voluminoso, inicialmente tratado como parapneumónico. Después de la compensación clínica, se realizó drenaje torácico, con salida de 3000mL de líquido. Evolucionó rápidamente con insuficiencia respiratoria aguda, necesitando ventilación mecánica. Tuvo dos extubaciones mal sucedidas y, debido a la evolución atípica, se realizó tomografía computadorizada, cuyos hallazgos fueron compatibles con edema de reexpansión. Después de soporte intensivo, evolucionó satisfactoriamente y, posteriormente, se diagnosticó tuberculosis pleural. COMENTARIOS Es importante el conocimiento de la patología, aunque sea rara en la población pediátrica (encontrados solamente cinco casos descriptos), para prevención, una vez que la tasa de mortalidad es muy alta. Se recomienda, entre otras medidas, que el vaciamiento de un derrame pleural sea lento y que el volumen total retirado no sobrepase 1500mL. .

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.

Evento com aparente risco de morte recorrente como manifestação inicial de síndrome miastênica congênita / Recurrent apparent life-threatening event as the first manifestation of congenital myasthenia / Evento con aparente riesgo de muerte recurrente como manifestación inicial de síndrome miasténico congénito

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.

Factors associated with complications of community-acquired pneumonia in preschool children.

OBJECTIVE: To identify socioeconomic factors and clinical factors associated with the development of complications in preschool children hospitalized with community-acquired pneumonia (CAP). METHODS: This was a prospective longitudinal study involving children (12-59 months of age) diagnosed with CAP and admitted to the pediatric wards of two hospitals in the metropolitan area of Campinas, Brazil. Children with cystic fibrosis, heart disease, pulmonary malformations, neurological disorders, or genetic diseases were excluded. The diagnosis of CAP was based on clinical and radiological findings. Data were collected from the medical records and with a semi-structured questionnaire. The subjects were divided into two groups (complicated and uncomplicated CAP). Socioeconomic and clinical variables were compared, and multivariate logistic regression analysis was performed. RESULTS: Of the 63 children included, 29 and 34, respectively, presented with uncomplicated and complicated CAP. No statistically significant differences were found between the groups regarding age at admission, gestational age, birth weight, gender, or socioeconomic variables. Significant differences were found between the groups regarding history of pneumonia (p = 0.03), previous antibiotic therapy (p = 0.004), time elapsed since the onset of CAP (p = 0.01), duration of fever prior to admission (p < 0.001), duration of antibiotic therapy (p < 0.001), and length of hospital stay (p < 0.001). In the multivariate analysis, only duration of fever prior to admission remained in the model (OR = 1.97; 95% CI: 1.36-2.84; p < 0.001). CONCLUSIONS: Biological variables, especially duration of fever prior to admission, appear to be associated with the development of complications in children with CAP.

Fatores associados às complicações em crianças pré-escolares com pneumonia adquirida na comunidade / Factors associated with complications of community-acquired pneumonia in preschool children

OBJETIVO: Identificar os fatores socioeconômicos e clínicos associados à evolução para complicações em crianças internadas com pneumonia adquirida na comunidade (PAC). MÉTODOS: Estudo longitudinal prospectivo em crianças diagnosticadas com PAC (12-59 meses de idade) internadas em enfermarias gerais de pediatria de dois hospitais na região de Campinas (SP). Os critérios de exclusão foram ter fibrose cística, cardiopatia, malformação pulmonar, neuropatias e doenças genéticas. PAC foi diagnosticada por características clínicas e radiológicas. Os dados foram coletados dos prontuários médicos e por um questionário semiestruturado. Os sujeitos foram divididos em dois grupos (PAC complicada e não complicada). Foram comparadas variáveis socioeconômicas e clínicas, e foi realizada análise de regressão logística multivariada. RESULTADOS: Das 63 crianças incluídas, 29 e 34, respectivamente, apresentaram PAC não complicada e PAC complicada. Não houve diferenças estatisticamente significantes entre os grupos quanto a idade na admissão, idade gestacional, peso ao nascer, gênero ou variáveis socioeconômicas. Houve diferenças significantes entre os grupos em relação a pneumonia anterior (p = 0,03), antibioticoterapia prévia (p = 0,004), tempo de início da doença (p = 0,01), duração da febre antes da internação (p < 0,001), duração da antibioticoterapia (p < 0,001) e tempo de internação (p < 0,001). Na análise multivariada, somente permaneceu no modelo a duração da febre antes da internação (OR = 1,97; IC95%: 1,36-2,84; p < 0,001). CONCLUSÕES: Variáveis biológicas, com destaque para o tempo de febre anterior à internação, parecem estar associadas com a evolução para complicação em crianças com PAC.
