- Doença Meningocócica Invasiva: Aplicação do Base Excess and Platelets Score numa Unidade de Cuidados Intensivos Pediátricos PortuguesaPublication . Martins, L; Mação, P; Pinto, C; Dionísio, T; Dias, A; Dinis, A; Carvalho, L; Neves, JFINTRODUCTION: Meningococcal infection has a high mortality and morbidity. Recently a new prognostic scoring system was developed for paediatric invasive meningococcal disease, based on platelet count and base excess â base excess and platelets score. The main objective of this study was to evaluate the accuracy of base excess and platelets score to predict mortality in children admitted to intensive care due to invasive meningococcal disease. MATERIAL AND METHODS: Observational study, with retrospective data collection, during a 13.5 years period (01/2000 to 06/2013). Mortality by invasive meningococcal disease and related factors (organ dysfunction and multi-organ failure) were analysed. The base excess and platelets score was calculated retrospectively, to evaluate its accuracy in predicting mortality and compared with Paediatric Risk of Mortality and Paediatric Index of Mortality2. RESULTS: Were admitted 76 children with invasive meningococcal disease. The most frequent type of dysfunction was cardiovascular (92%), followed by hematologic (55%). Of the total, 47 patients (62%) had criteria for multi-organ failure. The global mortality was 16%. Neurologic and renal dysfunction showed the strongest association with mortality, adjusted odds ratio 315 (26 - 3 804) and 155 (20 - 1 299). After application of receiver operating characteristic curves, Base Excess and Platelets score had an area under curve of 0.81, Paediatric Index of Mortality2 of 0.91 and Paediatric Risk of Mortality of 0.96. DISCUSSION: The Base Excess and Platelets score showed good accuracy, although not as high as Paediatric Risk of Mortality or Paediatric Index of Mortality 2. CONCLUSIONS: The Base Excess and Platelets score may be useful tool in invasive meningococcal disease because is highly sensitive and specific and is objectively measurable and readily available at presentation.
- Hérnias diafragmáticas traumáticas: revisão casuísticaPublication . Almeida e Sousa, JP; Baptista, JP; Martins, L; Pimentel, JAIMS: This study classifies cases of traumatic diaphragmatic hernias (TDH) in patients admitted to the Intensive Care Unit (ICU) of the Coimbra University Hospitals (HUC) from 1990 to 2004. METHODS: Retrospective analysis of 34 cases of TDH, studying anatomical location, place and time of diagnosis, complementary tests aiding diagnosis, herniated organs, associated traumatism, morbidity and mortality. RESULTS: Twenty-eight male and six female patients with an average age of 40.5 years +/- 20.5, average SAPS score 38.8. Average length of stay was 19.1 +/- 13.6 days, all suffered from closed traumatism and were put on artificial ventilation. The left-side diaphragm was more frequently affected (94.1%) then the right. Diagnosis in 19 cases was made up in the first six hours following the diagnosis of traumatism, in four cases within 12 hours and in the remaining cases between 48 hours and 16 years after traumatism. In 13 patients the diagnosis was established intra-operatively. The stomach was typically one of the herniated organs. The most frequently associated lesions at the thoracic level were pulmonary contusion, haemothorax and pneumothorax, and at the abdominal level, haemoperitoneum and splenic lesion. The rates for complications and mortality were 55.8% and 11.7% respectively. CONCLUSIONS: TDH mainly occurs on the left side through closed thoraco-abdominal trauma following road traffic accidents. This group of patients, on average younger than others admitted to ICU, presents a longer average hospitalisation period, but has lower rates of mortality and lower SAPS severity scores. The most commonly herniated organ was the stomach and the most frequently encountered lesions were cranial-encephalic, splenic and pleural traumatisms. Pre-operative diagnosis of diaphragmatic injuries is difficult and a high index of clinical suspicion is needed after thoraco-abdominal trauma. This diagnosis should always be considered a possibility in cases of closed thoraco-abdominal traumas.
