Lactate Clearance as a Marker of Mortality in Pediatric Intensive Care Unit.

Objectives: To correlate lactate clearance with Pediatric Intensive Care Unit (PICU) mortality. Methods: 45 (mean age 40.15 mo, 60% males) consecutive admissions in the PICU were enrolled between May 2012 to June 2013. Lactate clearance (Lactate level at admission – level 6 hr later x 100 / lactate level at admission) in first 6 hours of hospitalization was correlated to in-hospital mortality and PRISM score. Results: Twelve out of 45 patients died. 90% died among those with delayed/poor clearance (clearance <30%) compared to 8.5% in those with good clearance (clearance >30%) (P<0.001). Lactate clearance <30% predicted mortality with sensitivity of 75%, specificity of 97%, positive predictive value of 90%, and negative predictive value of 91.42%. Predictability was comparable to PRISM score >30. Conclusion: Lactate clearance at six hours correlates with mortality in the PICU.

Comparison of Alert-Verbal-Painful-Unresponsiveness Scale and the Glasgow Coma Score.

To determine how the AVPU (alert, verbal, painful, unresponsiveness) scale corresponds to Glasgow Coma Score (GCS), we compared the two scales. Two months to 12 years old patients were included in the study. The median GCS score (inter quartile range) for A/V/P/U were 14 (12-15), 11 (10-12), 6 (5.5-8) and 3 (3-4), respectively.

Signs of inflammation in children that can kill (SICK score): preliminary prospective validation of a new non-invasive measure of severity-of-illness.

BACKGROUND: Signs of Inflammation in Children that can Kill (SICK score) is a new severity-of-illness score. It uses the physical signs of the Systemic Inflammatory Response Syndrome (SIRS) and its continuum--the Multiple Organ Dysfunction Syndrome (MODS). The development of the score used multiple logistic regression model coefficients converted to integer scores that have been published earlier. AIMS: The present study was done to validate the scoring system by predicting outcomes in a fresh data set. SETTING: Intensive care unit in a tertiary referral hospital. DESIGN: Prospective. MATERIALS AND METHODS: 125 admissions to the intensive care unit were evaluated so that the SICK score and the PRISM score could be calculated. In-hospital mortality was noted. STATISTICAL ANALYSIS: Calibration (Hosmer-Lemeshow goodness of fit) and discrimination (area under the ROC curve) were used to measure performance. RESULTS: Of the 125 patients studied 23 died. The area under the ROC curve was 0.76 compared to 0.80 in the development sample. Using PRISM in the validation group, the ROC was 0.78. Calibration was excellent. CONCLUSION: The SICK score can predict severity of illness with nearly the same accuracy as the PRISM score. The SICK score can be calculated immediately on admission and can help to prioritize care for the more sick children who need urgent aggressive management. Larger studies, that includes all admissions to the hospital, will now need to be done.

Play in orphanages.

OBJECTIVES: This paper attempts to validate the programme of structured play lasting 90 minutes a day, for use in orphanages, to check if it can be replicated in other orphanages, with similar results. METHODS: A 2-week workshop on the structured play scheme was conducted at the Missionaries of Charity Orphanage in Delhi, the venue of the original project. 15 MOC sisters from 6 centers attended the workshop. The authors selected the MOC orphanage at Chandigarh to track the benefits of the programme. The development quotient of all the residents between the ages of 6 months - 3 years was assessed by a pediatric-clinical-psychologist using the Development Assessment Scale for Indian Infants (DAS II) scale. A reassessment of all these children was done again 3 months after initiating the programme of structured play here. RESULTS: The mean motor and mental scores at the orphanage in Chandigarh before the start of the intervention were 57.9 and 58.2 respectively. Post intervention assessments showed a rise of 23 points in both the scores. CONCLUSION: The development of children in orphanages rises dramatically after initiating a programme of play. The pre-intervention development scores is similar to that in a pilot study and the benefits after play was also similar. The play programme can be easily replicated in other orphanages with similar results.

Triage score for severity of illness.

OBJECTIVE: To evolve a triage scoring system for severity of illness based on clinical variables related to systemic inflammatory response syndrome (SIRS). DESIGN: Prospective study in a tertiary-care hospital. METHODS: Consecutive pediatric patients admitted to the ward or pediatric intensive care unit (PICU) were studied. The respiratory rate, heart rate, capillary refill time, oxygen saturation (SpO2), systolic blood pressure and temperature were noted, Sensorium level was assessed on AVPU score. Variables were based on SIRS criteria and criteria mentioned in Advanced Pediatric Life Support (APLS). Each study variable was scored as 0 or 1 (normal or abnormal) and total score for each child obtained. The survival at discharge was correlated with the study variables and the total score. Another score based on the magnitudes of the coefficients in multiple logistic regression analysis was computed and the correlation between this score and mortality was also studied. ROC curve analysis was performed to see the overall predictive ability of the score as well as a cut off at which maximum discrimination occurred. RESULTS: Of 1099 children studied, 44 died. Of the seven variables, only five variables were abnormal in the study subjects. Except heart rate and respiratory rate, all other variables and age showed significant association with survival status (P < 0.01). The mortality increased with increase in the number of abnormal variables: 0.4% 2.2% 6.1% 15.3% 19.4% and 29.4%for scores of 0,1,2,3,4 and 5 respectively and the linear trend was significant (P < 0.01). Mortality also increased with a decrease in age (P < 0.01). Children with a score of 2 or more (2 or more abnormal clinical variables) had significantly higher mortality as compared to those with no abnormal clinical variables (score = 0). Based on the regression coefficients, the maximum possible score was 9.8. Regression based score was found to predict survival status well. The area under the ROC curve was 0.887, indicating that overall 88.7% of the subjects could be predicted correctly. Maximum discrimination was observed at a score of 2.5 (sensitivity 84.1% specificity 82.2%). CONCLUSION: For triage scoring, any child with 2 or more abnormal clinical variables should be taken as serious that might lead to death. With a more detailed scoring, score of 2.5 can be taken as cut-off to select children who possibly need admission and closer observation.

Magnitude of the problem of retinopathy of prematurity. experience in a large maternity unit with a medium size level-3 nursery.

This report describes the extent and severity of retinopathy of prematurity (ROP) in a large maternity unit. The screening of 79 preterm babies showed that ophthalmic examinations should become an important part of neonatal care.

Prediction of mortality by application of PRISM score in intensive care unit.

OBJECTIVE: Prediction of mortality by application of Pediatric Risk of Mortality (PRISM) score in Pediatric Intensive Care Unit (PICU) patients under Indian circumstances. DESIGN: Prospective study. SETTING: PICU of a tertiary care multi-specialty hospital. METHODS: 100 sick pediatric patients admitted consecutively in PICU were taken for this study. PRISM score was calculated. Hospital outcome was recorded as (died/survived). The predicted death was calculated by the formula: RESULTS: Of 100 patients, 18 died and 82 survived. By PRISM score 49 children had the score of 1-9. The expected death in this group was 10.3% (n = 5.03) and the observed death was 8.2% (n = 4). Among 45 children with the score of 10-19, the expected mortality was 21.2% (n = 9.6) and observed was 24.4% (n = 11). There were 3 patients with the score of 20-29, the expected mortality in this group was 39.3% (n = 1.18) and observed mortality 33.3% (n = 1). There were 3 patients with score > or = 30, observed death 66.3% (n = 2) and expected mortality was 74.7% (n = 2.24). There was no significant difference between expected and observed mortality in any group. (p > 0.5). ROC analysis showed area under the curve of 72%. CONCLUSION: PRISM score has good predictive value in assessing the probability of mortality in relation to children admitted to a PICU under Indian circumstances.

Melas syndrome.

An 11 year old male presented with headache, vomiting and weakness of right side of body. One day after admission he developed right focal seizures. He had 5 previous episodes of stroke, the first at 11 months age. His milestones were normal upto the first episode but subsequent mile stones were delayed. His serum and CSF lactic acids were raised. Muscle biopsy showed ragged red fibres on modified Gomori-trichrome staining. His EEG, CT scan and MRI were normal this time. The child improved spontaneously after 7 days. His recovery time progressively became shorter with each episode of stroke. Maximum time for recovery was noted during first episode and least in current episode. This is the first report of Melas syndrome in Indian literature.

Determination of bone width in malnourished children under 5, and its inter relationship with mid arm muscle thickness, subcutaneous fat thickness and the mid upper arm girth.

The mid upper arm of 516 malnourished children (one to five years) were studied radiographically for changes in bone width, muscle mass and subcutaneous fat, of malnutrition at different ages. The data was studied by statistical analysis, determining the correlation coefficients of each of the factors. The findings indicate that previous assumptions about the components and the changes of the mid upper arm girth (MUG) in chronic severe malnutrition, were perhaps too simplistic.
