A 4-year-old boy has had a solitary sclerotic depressed plaque on the right anterior chest since birth. The histopathologic findings are consistent with morphea profunda: thickening, hyalinization, and homogenization of collagen bundles in the dermis and subcutaneous tissues, admixture with a prominent lymphocytic and plasma cell infiltrate, and sweat glands en-trapped between the thickened collagen bundles. We report a case of congenital solitary morphea profunda.

PURPOSE: This study was performed to investigate the epidemiology of enterovirus (EV) infections in children at a secondary hospital during recent 5 years. METHODS: We collected the cerebrospinal fluid, stool and throat swab samples from the pediatric patients with suspected EV infections in KEPCO Medical Center, Seoul, Korea from July 2006 to September 2010. EV detection and genotype identification were performed by RT-PCR at Korea Centers for Disease Control and Prevention. RESULTS: A total of 386 samples were collected from 277 patients during study period. Ninety-eight patients (35.4%) were diagnosed with EV infections. The RT-PCR positive rate was the highest in throat swab samples (48.3%). The median age of patient was 4.7 years (range, 0.1-12.5 years). Aseptic meningitis (50, 51.0%) was the most common clinical manifestation; herpangina (22, 22.4%) and hand-foot-mouth disease (18, 18.4%). One hundred EVs were isolated from 98 patients and 20 genotypes of EV were identified; Echovirus 30 (28 cases, 28%), Enterovirus 71 (12 cases, 12%), Echovirus 25 (10 cases, 10%), Echovirus 9 (9 cases, 9%) and Coxsackievirus A6 (8 cases, 8%). Aseptic meningitis caused by Echovirus 30 was the most common manifestation in 2008. There was no complicated case caused by Enterovirus 71. CONCLUSION: This study showed the epidemiology of confirmed EV infection in children from 2006 to 2010. There is a need for continuous surveillance of EV infections and its clinical manifestations.

PURPOSE:Mutations of the PROP1 (Prophet of PIT1) gene lead to combined pituitary hormone deficiency (CPHD), which is characterized by a deficiency of growth hormone (GH), thyroid stimulating hormone (TSH), luteinizing hormone (LH)/follicle stimulating hormone (FSH), prolactin (PRL) and adrenocorticotropic hormone (ACTH). We studied the PROP1 mutations in Korean children with hypopituitarism. METHODS:Twelve patients with congenital hypopituitarism were recruited from the Ajou University Hospital, Korea. The pituitary phenotype ranged from isolated growth hormone deficiency (IGHD) to CPHD. Clinical data, including endocrine and neuroradiological data were obtained from the medical records, and the DNA was collected and screened for mutations within PROP1 using polymerase chain reaction (PCR). The PCR products were sequenced directly. RESULTS:Nine patients had abnormal pituitary gland and three patients showed normal pituitary gland in magnetic resonance imaging (MRI). Endocrinologically, seven patients had IGHD and five had CPHD. Three of CPHD had GHD and hypogonadotrophic hypogonadism and the other two had GHD, central hypothyroidism, and ACTH deficiency. We identified no mutations in the PROP1 gene. However, three known polymorphisms were identified: The 27T->C (Ala9Ala) and the associated IVS1+3A->G in exon 1 were found in 25% of patient alleles sequenced. The 424G->A (Ala142Thr) in exon 3 change was identified in 4% of those sequenced. CONCLUSION:This study corresponds to the previous reports that PROP1 mutations are rare in sporadic cases of CPHD. The low mutation frequency in Korean patients may be due to ethnic-specificity or other candidate genes causing this disease. It is necessary to study PROP1 gene and the involved genes in more Korean patients.

OBJECTIVES: This study was performed to investigate the relationship between age of onset in late-life depression and T2 hyperintensities observed in the brain MRI, we tried to see part of pathophysiology of late-life depression. METHOD: The subjects consisted of 18 patients whose first depressive episode occurred before age 50, and 20 patients whose first depressive episode occurred after age 50 years, and 20 agematched controls. Depressive patients were diagnosed according to DSM-IV. Established hyperintensity rating systems were used to analyse the T2 weighted images and blood pressure, cholesterol level, DM, EKG were measured to compare the relationships. RESULTS: 1) Signal hyperintensities on T2 weighted image were more severe in late-life depressive patients whose first depressive episode after age 50 (p<0.05) and there is no significant difference between patients whose first episode before age 50 and age-matched control subjects. 2) Mild signal hyperintensities were observed in all elderly depressed patients and control subjects, but severe hyperintensities were observed in late-onset depression. 3) Signal hyperintensities were related to age, hypertension, blood cholesterol level (p<0.05). CONCLUSION: The late onset depressive patients had more white matter hyperintensities on T2 weighted image than early onset depressive patients. this results support previous hypothesis that white matter change is the important biological factor of late-onset elderly depression and old age, hypertension, hypercholesterolemia may be associated with signal hyperintensities.

We report a 36-year-old male with the bilateral visual field defect following LASIK was observed. Preoperatively, patient had high myopia(right. -7.25 0.75x18, left. -7.5-0.5x12), normal intraocular pressure(IOP)(right/left: 16/14 mmHg), normal visual field(Humphrey 30-2 visual field)and revealed the tilted discs with symetric optic nerve head cupping(cup-to-disc ratio, 0.70), parapapillary atrophy. Bilateral LASIK keratorefractive surgery was on the same day and intraoperative complication was not noted. After the first operative visit day, examination revealed uncorreted visual acuity right 0.8 and left 0.6 but scotoma was reported. Three months later, Humphrey 30-2 visual field revealed a near-superior altitudinal defect in the right eye and nasal side visual field defect in the left eye. Best corrected visual acuity was 1.0 in the right eye, 0.8 in the left eye. Repeated visual fields over a 11-month period postoperatively showed stability of the defect, with IOP of 12 mmHg to 15 mmHg in each eye. We considered LASIK uses a microkeratome vaccum ring to make a corneal flap, transient elevation of IOP alters the microcirculation of optic nerve head and may have precipitated visual field defect.
