RESUMEN
AIM: It is of critical importance to have internationally constructed tools to address early childhood development. The aim of this second phase of a two-phase study was to examine the sensitivity and specificity of the Guide for Monitoring Child Development (GMCD) in identifying developmental delay in four diverse countries. METHODS: The first phase of this 2011-2015 back-to-back study included 4949 children up to 42 months of age from primary healthcare centres in Argentina, India, South Africa and Turkey. Distribution curves were generated to show the ages when the children attained GMCD milestones and those that could be used across sexes and countries were placed in age ranges corresponding to the 85th and 97th percentile point estimates. Phase two examined a separately recruited sample of children in those countries to determine sensitivity and specificity of the GMCD. RESULTS: The validation phase of the 85 milestones in the GMCD identified delayed development in 30% of the 1731 children in the four countries. The sensitivity and specificity ranged from 0.71-0.94 and 0.69-0.82, respectively, for the total sample and the different age groups. CONCLUSION: The GMCD standardised in four diverse countries has appropriate accuracy for identification of children with developmental delay.

BACKGROUND: Knowledge about typical development is of fundamental importance for understanding and promoting child health and development. We aimed to ascertain when healthy children in four culturally and linguistically different countries attain developmental milestones and to identify similarities and differences across sexes and countries. METHODS: In this cross-sectional, observational study, we recruited children aged 0-42 months and their caregivers between March 3, 2011, and May 18, 2015, at 22 health clinics in Argentina, India, South Africa, and Turkey. We obtained a healthy subsample, which excluded children with a low birthweight, perinatal complications, chronic illness, undernutrition, or anaemia, and children with missing health data. Using the Guide for Monitoring Child Development, caregivers described their child's development in seven domains: expressive and receptive language, gross and fine motor, play, relating, and self-help. Clinicians examining the children also completed a checklist about the child's health status. We used logit and probit regression models based on the lowest deviance information criterion to generate Bayesian point estimates and 95% credible intervals for the 50th percentile ages of attainment of 106 milestones. We assessed the significance of differences between sexes and countries using predefined criteria and regions of practical equivalence. FINDINGS: Of 10â246 children recruited, 4949 children (48·3%) were included in the healthy subsample. For the 106 milestones assessed, the median age of attainment was equivalent for 102 (96%) milestones across sexes and 81 (76%) milestones across the four countries. Across countries, median ages of attainment were equivalent for all play milestones, 20 (77%) of 26 expressive language milestones, ten (67%) of 15 receptive language milestones, nine (82%) of 11 fine motor milestones, 14 (88%) of 16 gross motor milestones, and eight (73%) of 11 relating milestones. However, across the four countries the median age of attainment was equivalent for only two (22%) of nine milestones in the self-help domain. INTERPRETATION: The ages of attainment of developmental milestones in healthy children, and the similarities and differences across sexes and country samples might aid the development of international tools to guide policy, service delivery, and intervention research, particularly in low-income and middle-income countries.

Determination of the etiology of bacterial meningitis and estimating cost of disease are important in guiding vaccination policies. To determine the incidence and etiology of meningitis in Turkey, cerebrospinal fluid (CSF) samples were obtained prospectively from children (1 month-17 years of age) with a clinical diagnosis of acute bacterial meningitis. Multiplex PCR was used to detect DNA evidence of Streptococcus pneumoniae, Haemophilus influenzae type b (Hib), and Neisseria meningitidis. In total, 408 CSF samples were collected, and bacterial etiology was determined in 243 cases; N. meningitidis was detected in 56.5%, S. pneumoniae in 22.5%, and Hib in 20.5% of the PCR-positive samples. Among N. meningitidis-positive CSF samples, 42.7%, 31.1%, 2.2%, and 0.7% belonged to serogroups W-135, B, Y, and A, respectively. This study highlights the emergence of serogroup W-135 disease in Turkey and concludes that vaccines to prevent meningococcal disease in this region must provide reliable protection against this serogroup.

BACKGROUND: Prolonged application of topical steroids transiently suppresses the hypothalamic-pituitary-adrenal axis (HPA). Infants who are exposed to topical corticosteroids have greater risk for Cushing's syndrome or adrenocortical insufficiency caused by suppression of the HPA axis because glucocorticoids are highly absorbed through the diaper area. Here, we report six infants (four girls, two boys) aged between 3 and 8 months who were exposed to potent topical corticosteroids (clobetasol propionate and diflucortolone valerate) by the mother's application without prescription. METHODS: We examined the HPA axis and other side effects of the potent glucocorticoid therapy in these infants. After stopping the topical corticosteroid, serum AST, ALT, lipids, morning cortisol and ACTH levels were measured. A low dose ACTH stimulation test was carried out. Hydrocortisone was started for the prevention of glucocorticoid withdrawal syndrome and the dose was gradually decreased. Abdominal ultrasonography was performed to investigate hepatosteatosis. RESULTS: The ACTH stimulation test showed suppression of the HPA axis in these infants. Hepatomegaly was found in all infants and three of them had hepatosteatosis. Liver transaminase levels were elevated in five infants. Five patients have been followed for 6-14 months. One infant died due to generalized Cytomegalovirus infection. CONCLUSION: We emphasize that physicians should be alert for the dangerous side-effects of topical steroids and they should avoid long-term use. Furthermore, parents should be informed about the side-effects when topical steroid treatment is chosen.
