Clinical features of eczema herpeticum in atopic dermatitis in a single center

PURPOSE: This study evaluated the clinical characteristics and risk factors associated with atopic dermatitis patients complicated by eczema herpeticum. METHODS: This study included 45 patients under the age of 18 with atopic dermatitis complicated by eczema herpeticum in the disease group (ADEH+), and 50 patients under the age of 18 with atopic dermatitis without any episode of eczema herpeticum in the control group (ADEH−). We retrospectively reviewed the clinical features, treatment and prognosis of the 2 groups. RESULTS: In this study, eczema herpeticum occurred in 2.7% of the AD patients. No significant difference in percentage of boys or mean age was found between the ADEH+ and ADEH− groups. In the ADEH+ group, eczema herpeticum occurred more frequently in the head and neck. Severe atopic dermatitis, recurrent impetigo, IgE−mediated atopic dermatitis and food allergy were identified as the risk factors of eczema herpeticum. The mean white blood cell count, erythrocyte sedimentation rate, percent of eosinophils and total serum IgE were higher in the ADEH+ group than in the ADEH− group. More than 2 recurrences were confirmed in 12 patients (26.7%). CONCLUSION: In the ADEH+ group, skin lesions were dominant on the head and neck. We revealed that severe atopic dermatitis, frequent impetigo, IgE-mediated atopic dermatitis, and food allergy are risk factors for eczema herpeticum.

Meta-analysis on risk stratification of malignant ventricular tachyarrhythmic events in arrhythmogenic right ventricular cardiomyopathy / 영남의대학술지

BACKGROUND: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a cardiomyopathy characterized by predominant right ventricular fibro-fatty replacement, right ventricular dysfunction and ventricular arrhythmias. It is a rare but important cause of sudden cardiac death in children and young adults. A meta-analysis on risk stratification of major ventricular tachyarrhythmic events indicating the need for implantable cardioverter defibrillator therapy in ARVC was performed. METHODS: The pubmed database was searched from its inception to May 2015. Of the 433 citations identified, 12 were included in this meta-analysis. Data regarding major ventricular tachyarrhythmic events were retrieved in 817 subjects from the studies. For the variables, a combined odds ratio (OR) was calculated using a fixed-effects meta-analysis. RESULTS: Extensive right ventricular dysfunction (OR, 2.44), ventricular late potential (OR, 1.66), inducible ventricular tachyarrhythmia during electrophysiology study (OR, 3.67), non-sustained ventricular tachycardia (OR, 3.78), and history of fatal event/sustained VT (OR, 5.66) identified as significant risk factors (p < 0.0001). CONCLUSION: This meta-analysis shows that extensive right ventricular dysfunction, ventricular late potential, inducible ventricular tachyarrhythmia during electrophysiological study, non-sustained ventricular tachycardia, and history of sustained ventricular tachycardia/fibrillation are consistently reported risk factors of major ventricular tachyarrhythmic events indicating implantable cardioverter defibrillator therapy in patients with ARVC.

Herpes Zoster with Aseptic Meningitis in Immunocompetent Children: A Case Series

Primary clinical features of rash and neurological complications due to varicella zoster virus (VZV) reactivation are rare in a healthy population, especially in immunocompetent children. Early diagnosis and prompt treatment are delayed often due to their rarity. We present four immunocompetent children with VZV reactivation resulting in aseptic meningitis and herpes zoster affecting multiple cranial and spinal nerves. We reviewed the clinical manifestations, laboratory findings, treatment options and outcome of aseptic meningitis associated VZV reactivation. All patients presented with the typical skin lesion of VZV reactivation and definitive laboratory findings of central nervous system infection, without systemic inflammation. Initial manifestations of VZV reactivation included Ramsay Hunt syndrome, herpes zoster ophthalmicus, and herpes zoster affecting the left thoracic dermatomes 4–5. Intravenous acyclovir was administered and all patients recovered fully without any significant sequelae. VZV reactivation can lead to various neurological complications in immunocompetent children. Early recognition and treatment with acyclovir are important for improving the outcome of neurologic complications of VZV reactivation.
