The Griffiths Development Scales-Chinese (GDS-C): A cross-cultural comparison of developmental trajectories between Chinese and British children.

BACKGROUND: The Griffiths Mental Development Scales (GMDS) are used in many countries to assess the development of children from birth to 8 years. There is a need for accurate and culturally appropriate developmental assessment tools for Chinese children. Here, we adapted the GMDS for use in Chinese children and compare the developmental trajectories between Chinese and British children. METHODS: Children with typical development were recruited from 7 urban cities in China between 2009 and 2013. The Griffiths Mental Development Scales-Chinese (GDS-C) were adapted and used to assess the development of urban Chinese children. Developmental curves were computed for 6 subscales using learning management system methods and compare against the British curves from the Griffiths Mental Development Scales-Extended Revised (GMDS-ER). RESULTS: The GDS-C were used to assess the developmental status of 815 Chinese children. Plots of the 1st, 5th, 10th, 25th, 50th, 75th, 90th, 95th, and 99th percentiles, and full percentile tables were obtained, which showed similar trends to data from the British GMDS-ER. CONCLUSIONS: The Chinese developmental curves obtained from the GDS-C showed similarities and differences to the developmental curves from the British GMDS-ER. The development of urban Chinese children should be assessed with the culturally appropriate GDS-C.

Randomized, controlled trial of high-dose intravenous pyridoxine in the treatment of recurrent seizures in children.

To determine the efficacy of pyridoxine in treating seizures, 90 infants and children with recurrent convulsions primarily due to acute infectious diseases were enrolled in the present study. Forty patients were treated with high-dose pyridoxine (30 or 50 mg/kg/day) by intravenous infusion, and 50 subjects served as controls. Antiepileptic drugs and other therapies were similar in the two groups except for pyridoxine. Clinical efficacy criteria were based on the frequency of convulsions per day and on the duration of individual seizures after therapy was initiated. The results indicated that total response rates in the pyridoxine group and control group were 92.5% and 64%, respectively (chi-square = 14.68, P < .001). After initiation of therapy, seizures resolved after 2.4 +/- 1.4 days in the pyridoxine group and after 3.7 +/- 2.0 days in the control group (t = 3.67, P < .001). No adverse effects of pyridoxine were apparent during the observation period. We conclude that pyridoxine is an effective, safe, well-tolerated, and relatively inexpensive adjunct to routine antiepileptic drugs for treatment of recurrent seizures in children.

The use of blood glucose/cerebrospinal fluid glucose ratio in the diagnosis of central nervous system infection in infants and children.

The diagnosis of bacterial meningitis can be difficult nowadays when antibiotics are freely used in infants and children with fever due to infection, so that a positive smear or culture may be difficult to achieve. In areas where sophisticated methods of diagnosis may be hard to come by, the simple procedure of simultaneously estimating the blood and cerebrospinal fluid (CSF) glucose levels may be helpful in distinguishing bacterial meningitis from viral meningitis. 74 proven cases of bacterial meningitis and aseptic meningitis were investigated prior to treatment. There were 36 cases of bacterial meningitis and 38 cases of aseptic meningitis. The CSF glucose/plasma glucose ratio was calculated for each patient. The cases were divided into two groups; Group A with CSF glucose/plasma glucose ratio of (0.38-2.0) and Group B with CSF glucose/plasma glucose ratio of (0.1-0.35). In Group A, two out of 59 cases died while in Group B, nine out of 15 died (p < 0.01). 44 out of 59 in Group A recovered fully while only two out of 15 in Group B were cured (p < 0.01). It was also found that 54.2% in Group A were admitted in deep coma compared with 86.7% in Group B (p < 0.05) and 25.4% in Group A were admitted with seizures while 66.7% in Group B had convulsion (p < 0.01). Hence, a low CSF glucose/plasma glucose ratio was associated with a poor outcome. The mechanisms responsible for these findings are discussed especially with reference to the blood-brain barrier (BBB).(ABSTRACT TRUNCATED AT 250 WORDS)
