PURPOSE: To evaluate the usefulness of the Korean Developmental Screening Test (K-DST) for infants and children for developmental delay assessment. METHODS: This study was based on retrospective studies of the results of the K-DST, Preschool Receptive-Expressive Language Scale (PRES), Sequenced Language Scale for Infants (SELSI), Childhood Autism Rating Scale (CARS), Modified Checklist for Autism in Toddlers (M-CHAT), electroencephalography, magnetic resonance imaging, and extensive tests conducted in 209 of 1,403 patients, of whom 758 underwent the K-DST at the Korea University Guro Hospital between January 2015 and December 2016 and 645 were referred from local clinics between January 2015 and June 2016. RESULTS: Based on the K-DST results, the male children significantly more frequently required further or follow-up examination than the female children in most test sections, except for gross motor. The male children had notably lower mean scores than the female children. The PRES/SELSI results showed that when more further or follow-up evaluations were required in the K-DST communication section, significantly more problems in language delay or disorder emerged. When further or follow-up evaluation was required in the cognitive section in the CARS/M-CHAT, the possibility of autism increased significantly. A child tended to score low in the CARS test and show autism when further or follow-up evaluation was recommended in the K-DST. CONCLUSION: This study demonstrated the usefulness of the K-DST as a screening test early in the development of infants and children in Korea. Data of normal control groups should be examined to determine the accuracy of this investigation.

BACKGROUND: Henoch-Schӧnlein purpura (HSP) is a common vasculitis of childhood. Though HSP is usually self-limiting, severe complications can occur. The management for this condition has not been established yet. Thus, this nationwide study aimed at investigating epidemiological characteristics of children with HSP in Korea. The patterns of clinical practice with regard to the complications of the condition were also investigated. METHODS: This is a national population-based study that used the National Health Insurance Database. Children below 18 years who were diagnosed with HSP in Korea between 2006 and 2015 were enrolled. Data, such as age, sex, yearly and monthly distribution of HSP, hospitalization, re-hospitalization, comorbidities, and interventions were obtained. The use of steroids was also analyzed. RESULTS: A total of 56,841 children were enrolled. The annual incidence of HSP was 55.9 per 100,000 children. The peak age was 5 years. Spring was the most prevalent season. Sex (male) and young age (< 9 years) were risk factors of hospitalization. Younger children were more likely to be re-hospitalized and suspected with intussusception, arthritis, and nephritis. Only 4 children received laparotomy. In total, 57% were managed with steroids, and mean durations of medication were 4–5 days. Children who were hospitalized and those with comorbidities used steroids more frequently (P < 0.001). CONCLUSION: The annual incidence of HSP is 55.9 per 100,000 children which is higher in Korea than that in other countries. Younger children can have a more severe clinical course. This nationwide survey provides valuable information to understand HSP in children and to inspire further research on HSP.

The ideal approach in microvascular decompression(MVD) for hemifacial spasm(HFS) should provide the shortest and perpendicular route to the facial nerve root exit zone(FNREZ) with minimal cerebellar retraction and early cerebrospinal fluid drainage to avoid surgical morbidity. Small basal craniectomy anterior, posterior and superior to the condylar foramen would be the ideal approach for HFS, because it is maximal basal route to FNREZ. We performed this approach in 15 patients with HFS. Slightly curved skin incision 5cm in length was placed from inferior nuchal line 2cm posterior to the mastoid notch toward the angle of the mandible and the neck muscles were splitted. Posterior condylar emissary vein was elevated from condylar fossa. Small basal craniectomy extending from the inferior nuchal line to the condylar foramen was made. Jugular process was drilled out along the superior margin of the occipital condyle to expose distal sigmoid sinus and the junction of sigmoid sinus and jugular bulb. Lateral margin of foramen magnum posteroinferior to the condylar foramen was removed for early drainage of CSF from lateral medullary cistern. Dura was opened in T-shaped manner. With minimal elevation of cerebellum, arachnoid around lower cranial nerves can be dissected and FNREZ can be identified easily and safely. In conclusion, para-condylar foraminal approach can be considered to be minimally invasive and maximally safe in MVD for HFS.

BACKGROUND: Neuroprotective therapy is essential in the management of Parkinson's disease(PD). As symptomatic benefit of a treatment may clinically mask the disease progression, an evaluation of the effect of a neuroprotective therapy should be based on objective measurement of in vivo dopaminergic integrity: Nuclear imaging techniques such as SPECT or PET can visualize dopaminergic system using dopamine transporter ligands and show the promise for this purpose. The objective of this study is to examine the changes of dopamine transporter in the animal model of PD and those correlations with behavioral and biochemical changes. METHODS: We injected 6-hydroxydopamine into the substantia nigra in Sprague-Dawley rats to establish the unilateral PD model, and examined the rotation response after apomorphine injection as a behavioral aspect of the animal model. And we also measured the dopamine and DOPAC level in the striata and the dopamine transporter by [3H]-mazindol autoradiography. RESULTS: We observed that the rats showed turning behavior only after severe reduction of dopamine and DOPAC. There was a strong inverse correlation between rotation behavior and striatal dopamine, DOPAC and dopamine transporter density. There was a positive and strong linear-correlation between dopamine transporter density and dopamine or DOPAC levels. CONCLUSION: Measurement of dopamine transporter gives a good estimate of striatal dopamine level in an animal model of PD. In vivo measurement of dopamine transporter will give an objective information on the integrity of presynaptic nigrostriatal dopaminergic system.

A few case of deep granulomatous cutaneous infection have been reported in the Korean dermatologic literature, but Trichophyton(T.) mentagrophytes granuloma is rare. We report a case of Trichophytic granuloma caused by T. mentagrophytes in a 10-year-old male, who showed three, mild pruritic, coin to walnut-sized, erythematous plaques with indurations and crusts on the face for 1 month. Fungal culture of the biopsy specimen and scales of the lesion revealed T. mentagrophytes. Histopathologic examination of the skin lesion showed chronic granulomatous inflammation in the dermis and fungal hyphae in the hair shaft. After four weeks of terbinafine administration, lesions were cleared with mild erythematous macules.

Intussusception most commonly occurs in children, and in more than 90% of cases, no cause is found. In contrast, intussusception in adults is relatively rare but over 90% of patients have an organic lesion as the cause. Only 5% of cases of intussusception occur in adults and most involve the small intestine and are benign, whereas colonic intussusceptions are usually malignant. We report here a case of a 70-year-old man with intussusception who was referred with a one-day history of hematochezia and abdominal pain. The intussusception was caused by a sigmoid colonic tumor. The CT findings suggested that we could reasonably proceed to a sigmoidoscopy to confirm the site of obstruction. We speculated that the sigmoid colon tumor induced the anterograde intussusception. As with our patient, it is important to recognize the need to diagnose the primary lesion exactly and promptly.

Norovirus causes acute gastroenteritis, occasional afebrile seizures, and rarely encephalitis. We describe a child with cerebellitis due to norovirus that has not been reported previously. A previously healthy 2-year-old girl with a recent history of acute gastroenteritis, who presented with acute cerebellar ataxia. She exhibited marked truncal ataxia, was barely able to walk, and was prone to sitting or lying down. Multiplex PCR using stool samples revealed norovirus (genogroup II) and magnetic resonance imaging showed increased T2 signal in the hemi-cerebellum. Norovirus may be a potential pathogenic cause of acute cerebellitis in children.
