RESUMO
OBJECTIVE: Identify associated factors for recurrent wheezing (RW) in male and female infants. METHODS: Cross-sectional multicentric study using the standardized questionnaire from the Estudio Internacional sobre Sibilancias en Lactantes (EISL). The questionnaire was applied to parents of 9345 infants aged 12-15 months at the time of immunization/routine visits. RESULTS: One thousand two hundred and sixty-one (13.5%) males and nine hundred sixty-three (10.3%) females have had RW (≥3 episodes), respectively (p10 colds episodes (ORâ¯=â¯3.46; IC 95% 2.35-5.07), air pollution (ORâ¯=â¯1.33; IC 95% 1.12-1.59), molds at home (ORâ¯=â¯1.23; IC 95% 1.03-1.47), Afro-descendants (ORâ¯=â¯1.42; IC 95% 1.20-1.69), bronchopneumonia (ORâ¯=â¯1.41; IC; 1.11-1.78), severe episodes of wheezing in the first year (ORâ¯=â¯1.56; IC 95% 1.29-1.89), treatment with bronchodilators (ORâ¯=â¯1.60; IC 95% 1.22-2,1) and treatment with oral corticosteroids (ORâ¯=â¯1,23; IC 95% 0.99-1,52). Associated factors for RW for females were passive smoking (ORâ¯=â¯1.24; IC 95% 1.01-1,51), parents diagnosed with asthma (ORâ¯=â¯1.32; IC 95% 1,08-1,62), parents with allergic rhinitis (ORâ¯=â¯1.26; IC 95% 1.04-1.53), daycare attendance (ORâ¯=â¯1.48; IC 95% 1.17-1,88), colds in the first 6 months of life (ORâ¯=â¯2.19; IC 95% 1.69-2.82), personal diagnosis of asthma (ORâ¯=â¯1.84; IC 95% 1.39-2.44), emergency room visits (ORâ¯=â¯1.78; IC 95% 1.44-2.21), nighttime symptoms (ORâ¯=â¯2.89; IC 95% 2.34-3.53) and updated immunization (ORâ¯=â¯0.62; IC 95% 0.41-0.96). CONCLUSION: There are differences in associated factors for RW between genders. Identification of these differences could be useful to the approach and management of RW between boys and girls.

BACKGROUND: Idiopathic membranous nephropathy (IMN) has been linked to the lectin pathway, IgG4 and genetic susceptibility. We investigated the frequency of mannose-binding lectin2 (MBL2) gene polymorphisms and the serum ratio of IgG4 in patients with membranous nephropathy (MN). METHODS: Polymorphisms in the exon 1 of the MBL2 gene (codons 52, 54, and 57) and single base polymorphisms at positions -550 (HL) and -221 (XY) in the promoter region were evaluated in 60 patients compared to a control group (CG) of 101 blood donors. It established the frequency of polymorphisms and the serum ratio of IgG4 comparing 2 etiologies of MN: idiopathic (35 patients) and secondary to systemic lupus erythematosus (25 patients). RESULTS: Patients with MN had a 2.54-fold higher probability (95% CI 1.51-4.31) of carrying the O alelle, exon 1 variant, and 11.16-fold higher probability (95% CI 4.77-28.41) of having A/O genotype when compared to CG. The frequency of polymorphisms in the promoter region was similar between the groups. Combined genotypes generally related to the defective production of MBL (YA/O, XA/O and O/O) were more frequent in patients with MN (OR 7.11; 95% CI 2.69-21.27), when compared to controls. The median of serum ratio IgG4 was 5% for idiopathic MN and 3% for lupus MN patients (p = 0.016). CONCLUSIONS: Our data suggests that MBL2 polymorphisms may be associated with the activation of the lectin pathway by IgG4 subclass antibodies in MN.

INTRODUCTION: In Brazil, glomerulopathies are the third leading cause of chronic renal disease, accounting for 11% of dialysis patients. Studies on the prevalence of this disease in Northeastern Brazil are scarce. OBJECTIVE: The aim was to describe the findings of biopsies and to conduct a comparative analysis on the clinical laboratory presentation of primary glomerulopathies (PG) and secondary glomerulopathies (SG). METHODS: This was a retrospective study conducted at two public teaching hospitals in the state of Pernambuco, Northeastern Brazil. RESULTS: A total of 1151 biopsies performed between 1998 and 2016 were analyzed. The sample consisted of 670 biopsies of native kidneys, after excluding extra glomerular diseases and unsuitable material. PG were more frequent than SG (58% vs. 42%). There was a prevalence among PG of focal segmental glomerulosclerosis (43%). Membranoproliferative glomerulonephritis and collapsing glomerulopathy, accounted for 9% and 3% of the PG, respectively. For SG, the main etiologies were lupus nephritis (67%) and infections (10%). Female sex, hematuria and an elevated level of creatinine were related to a greater chance of SG, at multivariate analysis. An increase of proteinuria reduced this chance. Nephrotic syndrome was more common among the PG, while urinary abnormalities and nephritic syndrome prevailed in patients with SG. CONCLUSION: This is the first registry of glomerulopathies in Northeastern Brazil. It also presents a comparative analysis of the main clinical laboratory abnormalities of PG and SG, and includes the current classifications of glomerular diseases.

Resumo Introdução: No Brasil, glomerulopatias são a terceira causa de doença renal crônica terminal, responsáveis por 11% dos pacientes em diálise. Entretanto, estudos sobre a prevalência desta patologia no nordeste do Brasil são escassos. Objetivo: O objetivo foi descrever os achados das biópsias e analisar comparativamente a apresentação clínico laboratorial entre as glomerulopatias primárias (GP) e as glomerulopatias secundárias (GS). Métodos: Estudo retrospectivo, realizado em dois hospitais públicos de ensino do estado de Pernambuco, nordeste do Brasil. Resultados: Foram avaliadas 1.151 biópsias, de 1998 a 2016. A amostra foi composta por 670 biópsias de rins nativos, após exclusão de patologias extra glomerulares e materiais inadequados. GP foram mais frequentes do que GS (58% × 42%). Dentre as GP, houve predomínio de glomeruloesclerose segmentar e focal (GESF). Glomerulonefrite membranoproliferativa e glomerulopatia colapsante foram responsáveis por 9% e 3% das GP, respectivamente. Das GS, as etiologias principais foram nefrite lúpica (67%) e infecciosas (10%). Sexo feminino, hematúria e nível elevado de creatinina estiveram relacionadas a uma maior chance de GS na análise multivariada. Síndrome nefrótica foi mais comum dentre as GP, já anormalidades urinárias e síndrome nefrítica prevaleceram nos pacientes com GS. Conclusões: Este é o primeiro registro de glomerulopatias do nordeste do Brasil. Demonstrou-se também uma análise comparativa das principais alterações clínico laboratoriais das GP e GS, com classificações atualizadas das doenças glomerulares.

Dados de 800 pacientes pediátricos examinados na Emergência do Hospital Geral de Pernambuco do Instituto Materno-Infantil de Pernambuco foram analizados retrospectivamente. Em 14,75% desses pacientes foi indicado internamento, dos quais três quartos eram provenientes de classes sócio-econômicas menos favorecidas. A condiçäo sócio-econômica foi correlacionada com a distribuiçäo das doenças. A síndrome asmatiforme foi mais freqüente nas crianças pertencentes a famílias de maior renda e a pneumonia, mais freqüente entre os mais carentes

Um estudo descritivo sobre o uso abusivo de antimicrobianos em 173 crianças de 0 a 2 anos de idade atendidas no Ambulatório de Puericultura do Hospital das Clínicas da UFPE entre junho a agosto de 1992 foi realizado. Observou-se que 37 por cento das crianças estudadas já tinham feito uso de antimicrobianos e que a frequência do uso dessas drogas aumentava progressivamente com a idade. A amoxicilina e o sulfametoxazol-trimetoprim foram os antimicrobianos mais utilizados e os sintomas respiratórios aqueles que orientaram a prescrição da maioria dos antimicrobianos (48,4 por cento). A quase totalidade das prescrições foi realizada pelo pediatra. Este é um dado preocupante e provavelmente reflete o uso excessivo de antimicrobianos em nosso meio
