Impulse oscillometry (IOS) for detection of exercise induced bronchoconstriction in children with asthma ages 6-15 years.

OBJECTIVES: To determine the discriminatory value of various impulse oscillometry (IOS) parameters, and to find the cutoff value of the appropriate parameter for identifying exercise-induced bronchoconstriction (EIB) in children with asthma. METHODS: This cross-sectional study was conducted in India from October 2016 to March 2018 in children with asthma who were 6-15 years of age. One hundred and five children were enrolled and subjected to pre-exercise IOS and spirometry followed by free running treadmill test as an exercise challenge. All children could achieve minute ventilation >17.5-21 times of FEV1 during the exercise challenge test. Then, IOS and spirometry were performed at 10 ± 2, 20 ± 2, and 30 ± 2 min post-exercise challenge. EIB was defined as reduction of FEV1 ≥10% within 30 min of exercise. For purposes of analysis, the children were grouped into two categories: "EIB Present" or "EIB Absent". RESULTS: The prevalence of EIB in our study was 20.95% (n = 22). ΔR5max percentage within 30 min post-exercise (AUC 0.74; 95% CI: 0.64, 0.84) had the best discriminating capacity among all IOS parameters for identifying EIB. A cutoff value of 14.1% increase in R5 within 30 min post-exercise was obtained for detection of EIB (sensitivity-95.45%, specificity-50.6%, PPV-33.87% and NPV-97.67%). CONCLUSIONS: A percentage change in R5 with a cutoff value of 14.1% increase post-exercise had the best discriminatory capacity among all IOS parameters for detection of EIB in children with asthma. However, low positive predictive value (PPV) with high negative predictive value (NPV) made this cutoff value more apt to rule out EIB.

Short-term neurodevelopment and growth outcomes of very and moderate preterm Indian infants.

OBJECTIVE: To study the growth and neurodevelopmental outcome of very and moderate preterm infants (VMPT) compared to term appropriate-for-age (term AGA) infants at 18-months corrected age. METHODS: This prospective cohort study enrolled consecutively born 212 VMPT infants and 250 term AGA controls delivered during study period. OUTCOME MEASURES: Major neurodevelopmental impairment (NDI) defined as any one of cerebral palsy, motor (MoDQ) or mental developmental quotient (MoDQ) <70 on Developmental Assessment Scale for Indian infants, visual or hearing impairment, or epilepsy, and growth outcomes. RESULTS: Among 195 VMPT and 240 term AGA infants who completed follow-up, the frequency of major NDI was 12.8% and 2.5% respectively (RR 5.1; 95% CI [2.13-12.19]). Major NDI was higher among infants <28 weeks gestation (39%) and birthweight <1000 grams (27%). A quarter of VMPT infants exhibited wasting and 18% stunting than 7% each among controls. CONCLUSION: VMPT infants had a higher frequency of major NDI and growth failure at 18-months.

Effects of Exercise Intervention Program on Bone Mineral Accretion in Children and Adolescents with Cystic Fibrosis: A Randomized Controlled Trial.

OBJECTIVE: To evaluate effect of one year exercise intervention program on bone mineral accrual in children and adolescent with cystic fibrosis (CF). METHODS: Fifty-two CF children (mean age 149.79 mo) were randomized into experimental (15 boys and 10 girls) and control groups (15 boys and 12 girls). Experimental group performed prescribed exercises three times/week, while control group continued with routine physical activities for one year. Following were assessed at baseline and at one year: Bone mineral density (BMD) of whole body and lumbar spine, pulmonary function, exercise capacity, quality of life and habitual activity. RESULTS: Change in whole body and lumbar spine BMD over 12 mo in experimental group was lower by 0.006 g/cm2 (95% CI -0.02 to 0.02) and higher by 0.001 g/cm2 (95% CI -0.04 to 0.03) than controls, respectively. However, difference between groups was non-significant for both parameters. Experimental group had a significant improvement in their exercise capacity (p = 0.006), quality of life, and serum vitamin D (p = 0.007) levels. Differences between groups for changes in pulmonary function and habitual activity were non-significant. CONCLUSIONS: Exercise regime was not associated with significant improvement in BMD of CF patients, but it had a positive impact on both physical and psychological health of these patients.

Bone Mineral Density of Indian Children and Adolescents with Cystic Fibrosis.

OBJECTIVE: To document bone mineral density of children and adolescents with cystic fibrosis. DESIGN: Cross-sectional study. SETTING: Tertiary-care center of Northern India, July 2012 to August 2015. PARTICIPANTS: 52 children aged 6-18 years with cystic fibrosis and 62 healthy controls of similar age and sex. METHODS: Both patients and controls were stratified into two groups, as pre-pubertal and peri-/post-pubertal, and compared for whole body bone mineral density, measured using dual energy X-ray absorptiometry. Serum levels of calcium, phosphate, alkaline phosphatase, 25-hydroxyvitamin D and parathyroid hormone were measured in children with cystic fibrosis. RESULTS: Compared with controls, the mean (SD) bone mineral density of children with cystic fibrosis was significantly lower in both the pre-pubertal (0.7 (0.1) g/cm2 vs 0.9 (0.1) g/cm2; P<0.001)) and peri-/post-pubertal groups (0.9 (0.1) g/cm2 vs 1.1 (0.1) g/cm2; P<0.001). Also, the mean (SD) bone mineral apparent density of pre-pubertal and peri-/post-pubertal cystic fibrosis patients was lower than the controls (P <0.001 and P= 0.01, respectively). Thirty-seven (71.2%) cystic fibrosis patients had serum 25-hydroxyvitamin D level below 15 ng/mL. CONCLUSION: Bone mineral density of children with cystic fibrosis was significantly lower than controls; majority of them were vitamin-D deficient. Intervening at an early stage of the disease and providing optimal therapy involving simultaneous management of the several factors affecting bone mineral accretion may be beneficial in improving bone health of these patients.

Health Related Quality of Life in Indian Children with Cystic Fibrosis.

OBJECTIVE: This study was devised to translate Cystic Fibrosis Questionnaire-Revised to Hindi and administer it to Indian children and adolescents diagnosed with cystic fibrosis. DESIGN: Cross-sectional study. SETTING: This study was carried out in cystic fibrosis patients attending Pediatric Chest Clinic of a tertiary-care hospital in Northern India from July 2012 to December 2012. PARTICIPANTS: 45 children (6-13 years) and their parents, and 14 adolescents. Patients with unstable health in the past two weeks were excluded. INTERVENTION: Cystic Fibrosis Questionnaire- Revised translated in Hindi was administered. Clinical evaluation and scoring, throat swab cultures and spirometry were also done during the same visit. MAIN OUTCOME MEASURES: Health Related Quality of Life scores were the primary measures, and clinical scores, swab cultures and spirometry were secondary measures. RESULTS: Cronbachs alpha ranged from 0.020-0.863.The Factor analysis indicated that most test-items correlated more with competing scales than the intended scales. Convergence between self and proxy-rating was found to be dependent on the domain. The Cystic Fibrosis Questionnaire- Revised scores correlated well with clinical scores (r=0.65,P=0.011), Pseudomonas spp culture data and pulmonary function tests. There was an inverse relation between Health Related Quality of Life scores and age at diagnosis (r=-0.339, P=0.02). CONCLUSIONS: Hindi versions of Cystic Fibrosis Questionnaire- Revised: Child, Adolescent and Parents instruments will act as an important step towards data on Health Related Quality of Life of Indian patients with cystic fibrosis.

Slower rise of exhaled breath temperature in cystic fibrosis.

OBJECTIVE: To measure exhaled breath temperature in patients with cystic fibrosis. METHODS: 17 patients (6-18 years) with cystic fibrosis and 15 age- and gender-matched healthy controls were recruited in this cross sectional study. Exhaled breath temperature was measured in subjects recruited in both the groups with a device X-halo and analyzed as plateau temperature achieved and rate of temperature rise. RESULTS: Patients with cystic fibrosis showed no significant difference in plateau temperature [34.4(32.3-34.6) versus 33.9 (33.0-34.4)oC; P=0.35] while mean (SEM.) rate of temperature rise was significantly less in patients [0.09 (0.01) versus 0.14 (0.02) ƼC/s ; P=0.04] as compared to controls. CONCLUSIONS: There was a slower rise of exhaled breath temperature in patients with cystic fibrosis whereas plateau temperature was not significantly different from controls.

Interdisciplinary treatment of a periodontally compromised adult patient with multiple missing posterior teeth.

This article reports the comprehensive, interdisciplinary treatment of a 50-year-old periodontally compromised adult patient with multiple missing posterior teeth. After initial periodontal treatment, the maxillary first molars and right central incisor were intruded orthodontically. Miniscrews were used to intrude the maxillary first molars by 3 mm. The mandibular arch was restored with a tooth-supported overdenture. Root coverage of the maxillary right central incisor was performed using Alloderm (Biohorizons, Birmingham, Ala). At the end of the interdisciplinary therapy, the results were esthetically pleasing, with the patient's oral functions restored to the optimum. The emphasis of this report is to highlight the importance of integrating various specialties such as periodontics, orthodontics, endodontics, and restorative dentistry toward a common goal of improving the patient's oral health, function, and esthetics.

Comparison of effects of 3 and 7% hypertonic saline nebulization on lung function in children with cystic fibrosis: a double-blind randomized, controlled trial.

BACKGROUND: Beneficial effects of hypertonic saline on lung function in cystic fibrosis patients are well documented. However, the effects of various concentrations of hypertonic saline are not well studied. We, therefore, compared the effects of 3 and 7% hypertonic saline administered by nebulization on lung function in children with cystic fibrosis. METHOD: In a double-blind randomized controlled trial, 31 children with cystic fibrosis were randomized to receive either 3% saline or 7% saline nebulization twice daily for 28 days. Spirometry was performed and functional status was measured on Day 14 and 28. RESULTS: Of 31 children enrolled in the study, 30 completed the 28 days follow up (15 in each group). Percentage change in Forced Expiratory Volume during first second (FEV(1)) from baseline to Day 14 and on Day 28 was significantly higher in the group receiving 3% saline as compared with those receiving 7% saline inhalation. There was some decrease in FEV(1) (percentage predicted) immediately after 7% saline inhalation unlike 3% saline. The functional status remained comparable between the two groups. CONCLUSION: The results suggest that 3% hypertonic saline nebulization was better than 7% saline inhalation. There is a need for studies with larger sample size and longer duration to confirm our results.
