After 10 years of implementing the program of neonatal tetanus elimination from 1992 to 2001 in the Northern region, the tetanus toxoid coverage for pregnant and for child bearing age women have always been maintained at greater than 84%. The incidence of NT per 1000 live births has decreased, from 0.23 in 1994 to 0.07 in 2001. The disease has been eliminated at provincial level since 1995 and at district level since 1999.

To determine the validity of the following simple criteria used to determine protection of the infant from neonatal tetanus, we carried out an analysis of 646 neonatal tetanus cases that were reported in Vietnam from 1994 to 1998. 93% (602) of the 646 cases did not fit the criteria set for “protection at birth”. It was concluded that the criteria used to define “protection at birth” are valid and reliable. It's enough to be used by health workers as a simple management tool to monitor the neonatal tetanus elimination program, and assess the eligibility of women for further tetanus toxoid doses, according to the EPI schedule.

It is well-known that more than 50% of attention-deficit hyperactivity disorder (ADHD) cases also have comorbid psychiatric disorders. We evaluated the comorbid psychopathology of Korean children and adolescents with ADHD using a standardized diagnostic instrument. The Korean Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL-K) was administered and completed in 105 patients who had been referred to the outpatient and inpatient clinics at the Samsung Medical Center from March 2004 to May 2005. All of the cases were diagnosed as ADHD according to DSM-IV criteria. We analyzed their clinical characteristics and psychiatric comorbidities, and assessed the correlation of any comorbidity with gender, age and ADHD subtype. Among our 105 participants, 70 (66.7%) subjects were diagnosed with combined-type ADHD, 22 (21.0%) were the predominantly inattentive type, only 1 (1.0%) was determined to have the predominantly hyperactive-impulsive type of ADHD, and 12 (11.4%) were classified as not otherwise specified (NOS) ADHD. Eighty (76.2%) subjects had at least one comorbid disorder such as oppositional defiant disorder (n = 53, 50.5%), anxiety disorders (n = 35, 33.3%) and affective disorders (n = 15, 14.3%). Our patients ranged in age from five to 16 years. Among the factors including gender, age, and ADHD subtype, ADHD subtype was the only one significant to comorbidity in our study. The results of this study suggest that psychiatric comorbidity in Korean children with ADHD is similar to the results of previous studies in western countries. Out of all the ADHD subtypes, the combined-type group had a significantly higher ratio of comorbid disorders and psychopathologies.

Lithium salts are being used increasingly to treat patient with affective disorders, especially acute mania, or bipolar manic-depressive illness. For therapeutic effect the lithium content must be maintained at or above a particular level. Lithium poisoning due to overdosage may be seen occasionally, and its course is determined primarily by the rate of renal lithium elimination. A search is therefore indicated for procedures that could raise the lithium clearance. In a number of reports renal lithium excretion has been studied in relation to the excretion of water, sodium, potassium and hydrogen, but effects of sodium or water on the lithium excretion has not yet been clarified. Hence the present study was undertaken to investigate the effects of corticosteroid on the excretion of lithium ion. The female rat (Sprague-Dowley), weighing from 200 to 300g, was injected with 50mg/kg of lithium chloride intraperitoneally, and then injected with graded dosage of fludrocortisones and dexamethasone in each group. During the injected rats were incubated in metabolic cage, 24 hour urine of rats were collected. At 24 hours after injection, the rats were sacrificed with guillotine, the blood were collected. And then the concentrations of Na⁺, K⁺, Li⁺ of collected urine and serum were checked by Flame photometer. The results are summarized as follows 1. Fludrocortisone decreased the serum concentration of lithium and increased the urinary excretion of lithium. 2. In the group treated with low dose of dexamethasone (0.1 mg/kg), the serum concentration of lithium was decreased and high dose of dexamethasone (1 mg/kg) increased the urinary excretion of lithium. 3. Fludrocortisone increased the urinary [Na⁺]/[K⁺] in serum and decreased [Na⁺]/[K⁺] inurine, but opposite effects were occurred in dexamethasone. By above results, it may be concluded that corticosteroid increased the urinary excretion of lithium and decreased the serum concentration of lithium, but it seems to be there in no relationship between these effects of corticosteroid and of the renal Na⁺ or K⁺ transport.

OBJECTIVE: There are no published prevalence estimates of elimination disorders and their association with disruptive-behavior disorders among children in the Asian region using standardized diagnostic interviews. This study was conducted to determine the prevalence of elimination disorders and its association with disruptive-behavior disorders in a representative sample of children in Seoul, Korea. METHODS: The diagnosis of enuresis and encopresis was derived from parent-reported data for "enuresis and encopresis," collected using the Diagnostic Interview Schedule for Children, from a representative sample of 6- to 12-year-old children (n=1,645) who participated in the 2005 Seoul Child and Adolescent Mental Health Survey. Prevalence data for attention deficit and disruptive-behavior disorders were collected from the same sample. RESULTS: The overall 12-month prevalence of nocturnal enuresis and encopresis was 1.8% and 0.6%, respectively. Enuresis and encopresis prevalence in boys was significantly greater than that in girls. Enuresis and encopresis was most common at 7 to 9 years of age. Enuresis was significantly associated with ADHD (OR 2.6, 95% CI 1.0-6.9) and conduct disorder (CD; OR 4.7, 95% CI 1.0-22.4). CONCLUSION: Enuresis is significantly associated with ADHD and CD, so these conditions must be assessed together during the evaluation of children with enuresis.
