Bacterial Sepsis in Brazilian Children: A Trend Analysis from 1992 to 2006

BACKGROUND: The objective of this study was to determine the epidemiology of hospitalized pediatric sepsis in Brazil (1992–2006) and to compare mortality caused by sepsis to that caused by other major childhood diseases. METHODS AND FINDINGS: We performed a retrospective descriptive study of hospital admissions using a government database of all hospital affiliated with the Brazilian health system. We studied all hospitalizations in children from 28 days through 19 years with diagnosis of bacterial sepsis defined by the criteria of the International Classification of Diseases (ICD), (Appendix S1). Based on the data studied from 1992 through 2006, the pediatric hospital mortality rate was 1.23% and there were 556,073 pediatric admissions with bacterial sepsis with a mean mortality rate of 19.9%. There was a case reduction of 67% over.1992–2006 (p<0.001); however, the mortality rate remained unchanged (from 1992–1996, 20.5%; and from 2002–2006, 19.7%). Sepsis-hospital mortality rate was substantially higher than pneumonia (0.5%), HIV (3.3%), diarrhea (0.3%), undernutrition (2.3%), malaria (0.2%) and measles (0.7%). The human development index (HDI) and mortality rates (MR) by region were: North region 0.76 and 21.7%; Northeast region 0.72 and 27.1%; Central-West 0.81 and 23.5%; South region 0.83 and 12.2% and Southeast region 0.82 and 14.8%, respectively. CONCLUSIONS: We concluded that sepsis remains an important health problem in children in Brazil. The institution of universal primary care programs has been associated with substantially reduced sepsis incidence and therefore deaths; however, hospital mortality rates in children with sepsis remain unchanged. Implementation of additional health initiatives to reduce sepsis mortality in hospitalized patients could have great impact on childhood mortality rates in Brazil

Trombose venosa cerebral em uma criança com síndrome nefrótica

Nephrotic syndrome in infancy and childhood is known to be associated with a hypercoagulable state and thromboembolic complications, but cerebral sinovenous thrombosis (CST) is a very rare and serious one, with only a few isolated reports in the literature. A case is presented of a 9-year-old boy with nephrotic syndrome that acutely developed signs and symptoms of intracranial hypertension syndrome. CST was diagnosed on cranial CT and MRI and he gradually recovered after treatment with anticoagulants. The diagnosis of CST should be considered in any patient with nephrotic syndrome who develops neurologic symptoms. The discussion of this case, coupled with a review of the literature, emphasizes that early diagnosis is essential for institution of anticoagulation therapy and a successful outcome. This report also illustrates the difficulties that may be encountered in managing such a patient.A síndrome nefrótica na criança é sabidamente associada a um estado de hipercoagulabilidade e complicações tromboembólicas, entretanto a trombose venosa cerebral (TVC) é uma complicação muito rara e grave, com poucos relatos na literatura. Relatamos o caso de um menino de 9 anos com síndrome nefrótica que agudamente desenvolveu sinais e sintomas de uma síndrome de hipertensão intracraniana. TVC foi diagnosticada através de CT e IRM de crânio e o paciente gradualmente se recuperou após o tratamento com anticoagulantes. O diagnóstico de TVC deve ser considerado em qualquer paciente com síndrome nefrótica que desenvolva sintomas neurológicos. A discussão deste caso, associada à revisão da literatura, enfatiza que o diagnóstico precoce é essencial para instituição da terapia anticoagulante e para o bom prognóstico. Este relato também ilustra a dificuldade em manejar este tipo de paciente.Federal University of São PauloFederal University of São Paulo Department of PediatricsFederal University of São Paulo Department of Neurology and NeurosurgeryUNIFESP, Department of PediatricsUNIFESP, Department of Neurology and NeurosurgerySciEL

Anomalous left coronary artery from pulmonary artery: autogenous arterial tube for aortic implantation

Many surgical procedures for the implantation of anomalous left coronary artery from pulmonary artery have been described. A dual coronary system offers most benefit and is most advantageous for the patient. Two autogenous flaps of the pulmonary trunk and ascending aorta, without mobilizing the coronary artery, were created for use in this procedure. This technique was successfully used in an 8 month-old patient with severe myocardial dysfunction and moderate mitral regurgitation. This procedure allows 2 coronary systems to be repaired for any anatomic change of the left coronary artery without the use of prosthetic material. There were no technical complications. During the postoperative course minimal inotropic support was used. The magnetic resonance study, 11 months postoperative, showed wood How of the left coronary artery and mild mitral regurgitation. The operative technique was simple and its execution easy. The follow-up in the intermediate and late period showed the growth of this endothelized tube.UNIFESP, Div Cardiovasc Surg, BR-04087005 Sao Paulo, BrazilUNIFESP, Div Cardiovasc Surg, BR-04087005 Sao Paulo, BrazilWeb of Scienc

Conventional and conventional plus modified ultrafiltration during cardiac surgery in high-risk congenital heart disease

Background. This prospective nonrandomized study is the critical assessment of conventional ultrafiltration (CUF) and modified ultrafiltration (MUF) techniques and their efficiency in congenital heart disease surgeries. Use of cardiopulmonary bypass (C PB) in children is associated with body water retention as a consequence of prime volume and systemic inflammatory reaction. The CUF during CPB has reduced body water excess and the MUF after CPB, removes inflammatory mediators, improves hemodynamic performance, and decreases transfusion requirements.Methods. Forty-one patients, aged 9 to 36 months, submitted to surgical correction for cardiac defects, Using CPB, were divided into 2 similar groups: CUF (21 patients) operated between 1996-1997 were ultrafiltered during CPB, and CUF+MUF, (20 patients) operated between 1997-1998 and ultrafiltered during and after CPB. Postoperative duration of ventilator support, pediatric intensive care unit stay (PICU), hospital stay of the groups with and without preoperative pulmonary hypertension (PH), as well as transfusion requirement, hematocrit and platelet counts were compared.Results. There were no technical complications and a significant ultrafiltrate in the CUF+MUF group was observed as compared to the CUF group. No significant differences were observed between the CUF and CUF+MUF groups regarding ventilatory support, PICU stay and hospital stay. Requirements for red cell transfusion, Ht and platelet counts were not statistically different.Conclusions. CUF and CUF+MUF were safe and efficient methods for patient stabilization independent of diagnosis and complexity of surgery. Future clinical evaluation should address a larger population of patients to research the different variables.Univ Fed Sao Paulo, Div Cardiovasc Surg, BR-04104020 Sao Paulo, BrazilUniv Fed Sao Paulo, Div Cardiovasc Surg, BR-04104020 Sao Paulo, BrazilWeb of Scienc
