Role of Flexible Bronchoscopy in Ventilator-Dependent Neonates.

OBJECTIVE: To assess the usefulness and safety of flexible bronchoscopy in ventilated neonates with extubation failure. METHODS: This was a prospective observational study. Flexible bronchoscopy was done in eligible patients with failure of extubation form invasive ventilation. The main outcome measure was to find the presence of any anatomic or dynamic abnormalities of the airways of these patients and the organism profile of bronchoalveolar lavage (BAL) fluid. RESULTS: Forty-eight babies (68.8% preterm) were enrolled in the study. The most common finding on bronchoscopy was airway edema seen in 13 (27%) patients. BAL culture was positive in 29 (74%) patients. Overall treatment was modified in 35 (73%) patients based on bronchoscopy findings/BAL culture. Majority of infants (83.3%) tolerated the procedure very well. CONCLUSIONS: Flexible bronchoscopy provides useful information in the management of newborn babies with extubation failure.

Lactate clearance prognosticates outcome in pediatric septic shock during first 24 h of intensive care unit admission.

This study was undertaken to examine the clinical utility of lactate clearance as an indicator of mortality in pediatric septic shock, and to compare the performance of lactate clearance at 6, 12, and 24 h for predicting in-hospital and 60-day mortality. Pediatric patients with septic shock were prospectively studied. Vital signs, laboratory values, Pediatric Risk of Mortality Score, and pediatric logistic organ dysfunction score were obtained at presentation (hour 0), hour 6, hour 24 and over the first 72 h of hospitalization. Lactate clearance was obtained at 6, 12, and 24 h of hospital admission. Therapy received, outcome parameters of mortality, and duration of hospitalization were recorded. The primary outcome variable of 60-day mortality rate was 31.25%. Only lactate clearance at 6 and 24 h was significantly associated with mortality, with odds of 0.97 (95% CI, 0.951-981; p < 0.001) and 0.975 (95% CI, 0.964-0.986; p < 0.001), respectively. Approximately there was a 24% decrease in likelihood of mortality for each 10% increase in lactate clearance at 24 h. At a threshold value of 10% 6-h lactate clearance had a sensitivity of 0.948 and specificity of 0.571, while at a threshold of 20% 24-h lactate clearance had a sensitivity of 0.922 and specificity of 0.629. The comparison of clearance at 6 and 24 h using receiver operating characteristic showed that former was "fair" (area under the curve = 0.753) and later was "good" (area under the curve = 0.81) in predicting mortality in pediatric septic shock. CONCLUSION: We concluded that optimal lactate clearance in pediatric septic shock both during the early presentation and after the initial "golden hours" is associated with lower in-hospital and 60-day mortality. Further, 24-h lactate clearance appears superior to 6 h lactate clearance in predicting mortality in such patients.

Vitamin D status correlates with the markers of cystic fibrosis-related pulmonary disease.

BACKGROUND: The prevalence of Vitamin D deficiency remains high in cystic fibrosis despite daily supplementation. Vitamin D as an immunomodulator has been related to lower respiratory tract infections in children. The present study was undertaken to examine the association between vitamin D status and markers of cystic fibrosis-related pulmonary disease including exacerbations, bacterial colonization and pulmonary function. METHODS: The study includes review of records of 51 cystic fibrosis patients. Baseline patient variables and serum vitamin D levels were recorded. Based on vitamin D levels study patients were divided into three groups: vitamin-D sufficient (≥20 ng/mL), vitamin-D insufficient (12 to 20 ng/mL), and vitamin D-deficient (≤12 ng/ml). RESULTS: The proportion of children with deficient, insufficient and sufficient vitamin D levels were 47.1%, 15.7%, and 37.2%, respectively. Female sex, bacterial colonization and a greater number of exacerbations were associated with highest odds of developing vitamin D deficiency in patients with CF with 1.77 (0.22-4.61) (p = 0.002), 2.9(0.57-14.82) (p = 0.011), and 5.12 (1.28-20.50) (p = 0.021) respectively. The comparison of vitamin-D levels taken during exacerbations, colonization and during routine follow-up were significant [16.04 (7.42-27.91), 24.3 (15.5-32.4) and 48.54 (18.37-78.7) ng/ml, p < 0.001]. The FEV1 was determined in 24 patients; the comparison was significant between vitamin D-deficient and -sufficient groups [0.75 (0.717-0.777) vs. 0.82 (0.74-0.92) p < 0.05]. CONCLUSION: We concluded that vitamin D deficiency was highly prevalent in children with CF, despite daily supplementation of the vitamin in diet. Further, vitamin D deficiency was associated with a higher rate of pulmonary exacerbations and higher incidence of pulmonary bacterial colonization. In addition, in younger patients, low vitamin D levels were associated with reduced pulmonary function.

Prevalence of Depression among Caregivers of Indian Children with Cystic Fibrosis.

OBJECTIVE: To study the prevalence of depression among caregivers of children with cystic fibrosis and its impact on the health and well being of these children. METHODS: This cross-sectional study was conducted in a tertiary care hospital from September 2015 through August 2016. Forty one parents of children receiving treatment at the Cystic fibrosis (CF) clinic were approached to be part of the study. Six families declined the request resulting in 85% recruitment rate. The Centre for Epidemiological Studies Depression Scale (CES-D) was used to assess depression score among caregivers. The CES-D provides clinical cut-off scores of ≥16 that help in identifying persons at risk for depression. CES-D was completed by the parent closely associated with care of the affected child. Main outcome measure was to find the number of caregivers of patients who has score of ≥16 on CES-D scale, and its effect on growth and respiratory exacerbations of the affected child. RESULTS: A total of 23 fathers and 12 mothers participated in the study. The mean age of male and female caregivers was 30.9 ± 5.4 and 27.8 ± 4.7 y respectively. Eighteen (51.4%) caregivers scored above the clinical cut-off on the CES-D in the index study with mean score of 22.0 ± 4.0. The mean CES-D score among non-depressive caregivers was 7.76 ± 4.2. Significant negative association was found between parental depression and child's health. Children with high parental CES-D score suffered significantly more respiratory exacerbations (3.83 ± 1.2 episodes) in last six months than parents with low CES-D score (2.18 ± 1.28 episodes) (p value = 0.00). Similarly, stunting was more commonly seen in patients with high caregiver CES-D score (15 vs. 7; P value = 0.01). CONCLUSIONS: A very high prevalence of caregiver depression was found in cystic fibrosis, which negatively impacted care and well being of the affected patients. Depression was more common in families with poor economic and education level.

The Diagnostic Dilemma of Traumatic Lumbar Puncture: Current Standing of Cerebrospinal Fluid Leukocyte Corrections and Our Experience With Cerebrospinal Fluid Biomarkers.

OBJECTIVE: To assess the diagnostic efficiency of cerebrospinal fluid markers of procalcitonin, lactate, and cerebrospinal fluid/serum lactate ratio for detecting bacterial meningitis during traumatic lumbar puncture, and to compare these markers with routinely used uncorrected and corrected leukocyte measurements. METHODS: Infants aged ≤90 days with traumatic lumbar puncture were prospectively studied. The diagnostic characteristics of cerebrospinal fluid assays of uncorrected and corrected leukocyte count, procalcitonin, lactate, and lactate ratio were described and compared. RESULTS: Considering the area under the curve (95% CI) analysis and standard cutoff values, the lactate-ratio (0.985 [0.964-0.989] at cutoff 1.2) had the best test indexes for identifying meningitis, followed by lactate (0.964 [0.945-0.984] at cutoff 2.2 mmol/L) and procalcitonin (0.939 [0.891-0.986] at cutoff 0.33 ng/mL) measurement, whereas the corrected total leukocyte count assay (0.906 [0.850-0.962] at cutoff 350 cells/mm3) had diagnostic properties moderately superior to uncorrected total leukocyte count measurement (0.870 [0.798-0.943] at cutoff 430 cells/mm3). CONCLUSION: Cerebrospinal fluid levels of procalcitonin, lactate, and lactate-ratio are reliable markers to diagnose bacterial meningitis in blood-contaminated cerebrospinal fluid.

Flexible Bronchoscopy in Non-resolving Pneumonia.

OBJECTIVE: To study the utility of diagnostic flexible bronchoscopy and bronchoalveolar lavage (BAL) in children with non-resolving pneumonia. METHODS: This was a cross-sectional study conducted in a tertiary care hospital from July 2015 through June 2016. Fifty-two consecutive children of both genders from 1 mo to 14 y of age with a diagnosis of non-resolving pneumonia were included. Flexible bronchoscopy was done in all patients with or without bronchoalveolar lavage (BAL). BAL was sent for gram staining, culture, gene expert™ and lipid laden macrophages examination. Main outcome measures were to find any morphological abnormality in the tracheobronchial tree and organism profile of a positive BAL culture. RESULTS: During the period of 12 mo, 52 consecutive patients of non-resolving pneumonia were enrolled. Median (IQR) age of the study population was 12 (68.8) mo. Mean ± SD duration of illness was 22.7 ± 5.6 d. Flexible bronchoscopy was found to be very safe and effective tool that directly led to definitive diagnosis in 30.7% of cases. It was positive for different organisms in 22 (52.3%) children. Neglected foreign body was seen in five patients. CONCLUSIONS: Non-resolving pneumonia is often an area of clinical dilemma. Bacterial infections are the commonest etiology. Non-infectious causes like tracheobronchomalacia and foreign body aspiration are other important etiologies to be looked for. Early bronchoscopy and bronchoalveolar lavage analysis can play a crucial role in the evaluation of these patients and may provide an important clue or strongly support the specific diagnosis.

Childhood obesity.

Obesity is increasing at an alarming rate throughout the world. Today it is estimated that there are more than 300 million obese people world-wide. Obesity is a condition of excess body fat often associated with a large number of debilitating and life-threatening disorders. It is still a matter of debate as to how to define obesity in young people. Overweight children have an increased risk of being overweight as adults. Genetics, behavior, and family environment play a role in childhood overweight. Childhood overweight increases the risk for certain medical and psychological conditions. Encourage overweight children to expand high energy activity, minimize low energy activity (screen watching), and develop healthful eating habits. Breast feeding is protective against obesity. Diet restriction is not recommended in very young children. Children are to be watched for gain in height rather than reduction in weight. Weight reduction of less than 10% is a normal variation, not significant in obesity.
