PURPOSE: This study aimed to analyse laboratory values according to fever duration, and evaluate the relationship across these values during the acute phase of Kawasaki disease (KD) to aid in the early diagnosis for early-presenting KD and incomplete KD patients. METHODS: Clinical and laboratory data of patients with KD (n=615) were evaluated according to duration of fever at presentation, and were compared between patients with and without coronary artery lesions (CALs). For evaluation of the relationships across laboratory indices, patients with a fever duration of 5 days or 6 days were used (n=204). RESULTS: The mean fever duration was 6.6±2.3 days, and the proportions of patients with CALs was 19.3% (n=114). C-reactive proteins (CRPs) and neutrophil differential values were highest and hemoglobin, albumin, and lymphocyte differential values were lowest in the 6-day group. Patients with CALs had longer total fever duration, higher CRP and neutrophil differential values and lower hemoglobin and albumin values compared to patients without CALs. CRP, albumin, neutrophil differential, and hemoglobin values at the peak inflammation stage of KD showed positive or negative correlations each other. CONCLUSION: The severity of systemic inflammation in KD was reflected in the laboratory values including CRP, neutrophil differential, albumin, and hemoglobin. Observing changes in these laboratory parameters by repeated examinations prior to the peak of inflammation in acute KD may aid in diagnosis of early-presenting KD patients.

BACKGROUND: This study aimed to evaluate the clinical and radiological outcomes of arthroscopic bioabsorbable screw fixation in osteochondritis dissecans (OCD) in adolescent patients with unstable lesions causing pain. METHODS: The study included 11 patients (10 males and 1 female) with OCD who underwent arthroscopic bioabsorbable screw fixation between July 2007 and February 2014 and were available for follow-up for more than 12 months. The mean age at diagnosis was 16.3 years (range, 11 to 19 years), and the average follow-up period was 51 months (range, 12 to 91 months). Clinical results were evaluated using the Knee Injury and Osteoarthritis Outcome Score (KOOS), Lysholm knee score, and International Knee Documentation Committee (IKDC) score measured before surgery and at follow-up. Functional evaluation was made using the Tegner activity scale. Magnetic resonance imaging (MRI) and second-look arthroscopy were performed at the 12-month follow-up. RESULTS: Between the preoperative assessment and follow-up, improvements were seen in the KOOS (range, 44.9 to 88.1), Lysholm knee score (range, 32.6 to 82.8), and IKDC score (range, 40.8 to 85.6). The Tegner activity scale also improved from 2.8 to 6.1. Based on postoperative MRI, there were eight Dipaola grade I cases and three grade II cases. No complications due to fixation failure developed in any case. Second-look arthroscopy at 12 months postoperatively revealed that the lesion was covered with cartilage in all cases. CONCLUSIONS: For unstable OCD lesions causing pain in adolescents, arthroscopic bioabsorbable screw fixation provided favorable outcomes with reduced pain and restoration of movement. Therefore, it should be considered as an effective treatment for OCD.

BACKGROUND: Mycoplasma pneumoniae (MP) pneumonia is a self-limiting disease, but some patients complain of progressive pneumonia, despite of appropriate antibiotic treatment. We aimed to introduce the role of immune-modulators (corticosteroid and/or intravenous immunoglobulin, IVIG) treatment for childhood MP pneumonia based on previous our experiences. MATERIALS AND METHODS: A retrospective case series analysis for 183 children with MP pneumonia was performed. MP pneumonia patients were diagnosed by two Immunoglobulin M (IgM) tests: the micro-particle agglutination method (> or =1:40) and the cold agglutination test (> or =1:4), and were examined twice at the initial admission and at discharge. Among 183 MP pneumonia patients, 90 patients with persistent fever for over 48 hours after admission or those with severe respiratory symptoms and signs received additional prednisolone (82 patients, 1 mg/kg/day) or intravenous methylprednisolone (8 patients, 5-10 mg/kg/day) with antibiotics. Four patients with aggravated clinical symptoms and chest radiographic findings after corticosteroid treatment received IVIG (1 g/kg/day, 1-2 doses). RESULTS: Mean age of 183 patients was 5.5 +/- 3.2 years (6 months-15 years), and the male: female ratio was 1.1:1 (96:87). Fifty-seven patients (31%) were seroconverters and 126 seropositive patients showed increased diagnostic IgM antibody titres during admission (over 4 folds). The majority of the patients who received corticosteroids (86/90 cases) showed rapid defervescence within 48 hours with improved clinical symptoms, regardless of the used antibiotics. Also, 4 patients who received additional IVIG improved both clinically and radiographically within 2 days without adverse reaction. CONCLUSIONS: In the era of macrolide-resistant MP strains, early additional immune-modulator therapy with antibiotics might prevent from the disease progression and reduce the disease morbidity without adverse reaction.

BACKGROUND: Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease with genetic and environmental backgrounds. While the prevalence of AD is increasing, many patients lack accurate information and understanding about AD. OBJECTIVE: This study was performed to investigate the understanding of AD among Korean AD patients. METHODS: We developed a survey instrument to assess patient understanding of AD. Surveys were conducted over a 6-month period (from May 2010 to October 2010) among 415 patients with AD who visited 10 dermatology clinics at a university teaching hospital affiliated with the Korean Atopic Dermatitis Association. RESULTS: We identified points of understanding in Korean AD patients, such as knowledge and attitudes about AD, awareness of AD treatment, reliability of health care providers and information sources, and acting with AD treatment. As the results of this survey, it was confirmed that the patients' understanding of the cause and prognosis of AD was relatively inadequate, and it could be seen that the perception of the negative attitude toward the medical treatment of AD and inconveniences caused by AD was high. However, the results of the survey on the perception about the medical treatment methods of AD showed that they perceived medical doctors' treatment and prescriptions to have the best curative value, and as the criteria for choosing the treatment methods for AD, they chose the curative value rather than safety and cost. With regard to the information source for AD, they evaluated the treatment postscript on the internet sites and reliability of news media more highly than other information sources, and they responded that the main channel through which they obtain information related to AD was the medical doctors' explanations. CONCLUSION: We conducted the first systematic questionnaire survey to assess the understanding of AD among Korean AD patients. The results of this survey indicate that in the education and promotion on AD patients, additional education with regard to the cause and prognosis of AD is needed, and it is considered that efforts should be made to reduce the negative perception of AD through smooth communication with the medical team. In education and promotion related to AD, treatment postscripts on news media and the internet sites should also be addressed. Ultimately, the patients' self-discipline capabilities should be reinforced through proper education and development of programs related to AD.

Quantification of quality of life (QOL) related to disease severity is important in patients with atopic dermatitis (AD), because the assessment provides additional information to the traditional objective clinical scoring systems. To document the impact of AD on QOL for both children and adults as well as to quantify the relationship with disease severity, QOL assessments were performed over a 6-month period on 415 patients with AD. A questionnaire derived from the Infants' Dermatitis Quality of Life Index (IDQOL), the Children's Dermatology Life Quality Index (CDLQI) and the Dermatology Life Quality Index (DLQI) was used to determine the QOL for 71 infants, 197 children and 147 adults, respectively. To measure AD severity, both the Rajka & Langeland scoring system and the Scoring of Atopic Dermatitis (SCORAD) index were used. The mean scores were as follows: 7.7 +/- 5.5 for IDQOL, 6.6 +/- 6.3 for CDLQI, and 10.7 +/- 7.9 for DLQI. In conclusion, these QOL scores are correlated with AD severity scores as estimated by the Rajka & Langeland severity score and the SCORAD. The outcome of the QOL instruments in this study demonstrates that atopic dermatitis of both children and adults affects their QOL.

This article is to review neurobiology of attention-deficit/hyperactivity disorder (ADHD) and pharmacological properties of Osmotic-Controlled Release Oral delivery System Methylphenidate (OROS MPH)(Concerta Oros(R)) in celebration of its one-decade clinical experiences in Korea. ADHD is a highly heritable neurodevelopmental disorder, characterized by age-inappropriate inattention, hyperactivity and impulsiveness. The symptoms of ADHD are consistent with dysfunction of the prefrontal cortex (PFC). The PFC functions such as working memory and executive function are powerfully modulated by the catecholamine neurotransmitters, dopamine (DA) and norepinephrine (NE). Methylphenidate (MPH) is a first line treatment for children and adolescents with ADHD in Korea. MPH improves the PFC functions with the mechanism of action being modulation of DA and NE tones by blocking both dopamine transporter (DAT) and norepinephrine transporter (NET). Stimulation of D1 and NE alpha2 receptors on the postsynaptic neurons may be its main mechanisms of action which improve working memory and behavioral inhibition in patients with ADHD. OROS MPH, one of long-acting MPH, employs an osmotic-releasing oral system (OROS), which has been designed to have 12 hour duration of effect, which permits oncedaily dosing, which has been shown to be as effective as 3-times-a-day immediate-release formulation of MPH (IR MPH). Recently there is growing evidence that OROS MPH has positive effects even on adults with ADHD, in multidimensional aspects; cognitively, emotionally and functionally.

PURPOSE: In some girls with central precocious puberty (CPP), growth velocity (GV) decreases below the age-appropriate normal range during gonadotropin-releasing hormone agonist (GnRHa) treatment. The purpose of this study was to investigate clinical and laboratory factors related to changes in GV during GnRHa treatment in girls with CPP. METHODS: We analyzed clinical and laboratory data of 49 girls (aged 7.8+/-0.5 years) with idiopathic CPP who were treated with GnRHa. GV, height standard deviation score (SDS), hormonal parameters, pubertal stage, chronological age and bone age (BA) were evaluated. RESULTS: GV during the first year of GnRHa treatment was 5.9+/-1.0 cm/yr and decreased significantly to 5.4+/-1.1 cm/yr during the second year of treatment (P = 0.005). GV during the third year (5.0+/-1.0 cm/yr) was not different from GV during the second year. During the second year of treatment, 8.2% and 36.7% of the girls had a GV < 4 cm/yr and < 5 cm/yr, respectively. Girls with relatively low GV during the second year of treatment (< 5 cm/yr) showed higher risk of advanced BA (> or = 11 yr) at 1 year (55.6% vs. 19.4%; odds ratio [OR], 5.2; P = 0.022). In multivariate logistic regression analysis, more advanced BA at 1 year (OR, 6.1; 95% confidence interval [CI], 1.57-23.87) and lower height SDS for BA at 1 year (OR, 0.24; 95% CI, 0.06-0.94) were associated with relatively decreased GV (< 5 cm/yr) during the second year of GnRHa treatment. CONCLUSION: GV during and after the second year of GnRHa treatment in girls with idiopathic CPP remains within the normal prepubertal range, and relatively low GV during GnRHa treatment is associated with more advanced BA and lower height SDS for BA.
