A bstract Aims and objectives Utility of pediatric logistic organ dysfunction-2 (PELOD-2) score on day 1 within 1 hour of admission in predicting mortality in children admitted in pediatric intensive care unit (PICU). Background Various scoring systems aid to evaluate the patient's mortality risk in the intensive care unit (ICU) by assigning a score and predicting the outcome. Critically ill children are characterized by large variations in the normal body homeostasis. These variations can be estimated by the change of the physiological variables from the normal range. Various scores are constructed from deviations of these changed variables. One such score, the PELOD-2 score, is used to predict mortality of patients admitted in PICU. Materials and methods This study was carried out at a tertiary care center in central India to study the utility of PELOD-2 score within 1 hour of admission to predict mortality in patients admitted in PICU. Results Total 129 patients were included in this study with mean age of 67 months. The system with highest admission was central nervous system with 42 children and 16.6% mortality, whereas those 7 patients with hematological system involvement had highest mortality of 28.5%. The mortality rate was 15.55%. In our study for PELOD-2 within 24 hours of admission, the area under receiver operating curve was 0.87 and the Hosmer–Lemeshow test was p = 0.42. Conclusion Pediatric logistic organ dysfunction-2 score in our study had significant association with mortality along with the Hosmer–Lemeshow goodness-of-fit test showing a good prediction of mortality.

Background: The mortality in pediatric and neonatal critical care units can be predicted using scores. Prediction of mortality using (PRISM III) score in first 24 hours of admission in pediatric intensive care unit (PICU) and neonatal intensive care unit (NICU).Methods: Pediatric cases below 14 years with necessary investigations admitted in PICU and neonates in NICU during the period 1st August 2009 to 31 July 2011. Post-operative and patients with malformations or malignancy were excluded. A prospective observational study carried out at tertiary care rural hospital having 10 bedded well equipped PICU and NICU each. In subjects fulfilling inclusion criteria, PRISM III score which includes 17 variables was calculated within 24 hours of admission. The outcome at discharge was determined as non-survival or survival.Results: With increasing PRISM III score there was increase in mortality. PRISM III score offered a good discriminative power with the areas under the ROC curve > 0.86 (95% CI). Among different variables minimum systolic blood pressure, pupillary reflex, mental status (GCS), acidic pH, total co2, BUN, platelet count and PTT showed very high significant association with the mortality and Pco2, PaO2, temperature, potassium and creatinine showed significant association with mortality. Variables like Heart rate, Glucose, Alkaline pH and WBC count showed no significant association with the mortality.Conclusions: PRISM III score can be effectively used as a reflector of severity of illness.

Background:The objective of this cadaveric study was to analyze the effects of iatrogenic pedicle perforations from screw misplacement on the mean pullout strength of lower thoracic and lumbar pedicle screws. We also investigated the effect of bone mineral density (BMD), diameter of pedicle screws, and the region of spine on the pullout strength of pedicle screws.Materials and Methods:Sixty fresh human cadaveric vertebrae (D10–L2) were harvested. Dual-energy X-ray absorptiometry (DEXA) scan of vertebrae was done for BMD. Titanium pedicle screws of different diameters (5.2 and 6.2 mm) were inserted in the thoracic and lumbar segments after dividing the specimens into three groups: a) standard pedicle screw (no cortical perforation); b) screw with medial cortical perforation; and c) screw with lateral cortical perforation. Finally, pullout load of pedicle screws was recorded using INSTRON Universal Testing Machine.Results:Compared with standard placement, medially misplaced screws had 9.4% greater mean pullout strength and laterally misplaced screws had 47.3% lesser mean pullout strength. The pullout strength of the 6.2 mm pedicle screws was 33% greater than that of the 5.2 mm pedicle screws. The pullout load of pedicle screws in lumbar vertebra was 13.9% greater than that in the thoracic vertebra (P = 0.105), but it was not statistically significant. There was no significant difference between pullout loads of vertebra with different BMD (P = 0.901).Conclusion:The mean pullout strength was less with lateral misplaced pedicle screws while medial misplaced pedicle screw had more pullout strength. The pullout load of 6.2 mm screws was greater than that of 5.2 mm pedicle screws. No significant correlation was found between bone mineral densities and the pullout strength of vertebra. Similarly, the pullout load of screw placed in thoracic and lumbar vertebrae was not significantly different.
