A 20-year-old female, who had been treated with topical PUVA therapy for her vitiligo, developed characteristic skin lesions of disseminated superficial artiric porokeratosis(DSAP). All of her three sisters had vitiligo and had been treated with topica PUVA, hut only one developed DSAP lesion. Her mother had had DSAP lesions on expcsec areas for 20 years. DSAP shows an autosomal dominant mode of inheritance, and is charaterized by multiple ciark brownish keratotic papaules surrounded by slightly elevatied order. The exacerbation of the lesion by exposure t.o UV lignt indicates that the regulatingene for DSAP is related to sunlight. 1-lerein we reported a case of DSAP induced by topica] PUVA therapy in one patient during management of familial vitiligo in 3 sisters.

Verrucous carcinoma, a distinct variant of well differentiated squamous cell carcinoma, was originally described as an entity by Ackerman. This histologically benign lesion features relentless local growth and little tendency to metastasize. The commonest location of verrucous carcinoma is the oral cavity. Less frequently, the tumor originates in the squarnous mucosa, skin of the genitalia(glans penis, vulava, vagina, scroturn and perineum), nasal fossa, the larynx or the sole. Now we report a case of verrucous carcinoma developed on the retroauricular area in a 49-year-old man. He was treated by surgical excision followed by skin graft. This appears to be the first reported case arising on the retroauricular area.

Open discectomy is one of usual treatment for herniated intervertebral disc. We may expect the reduction of height of intervertebral disc due to decreased volume by partial resection of herniated disc. But the effect of decreased height of intervertebral disc space to posterior joint and spinal canal has not been identified, and the correlation between the amount of reduced height and the changes of range of motion has been undetermined. Thus, we analyzed radiologic changes of disc height and segmental motion by the flexion-extension view in 20 patients who had undergone discetomy for prolapsed intervertebral disc from June 1989 to January 1991 who could be followed up for 3 years or more. As a result, lumbar discetomy associates with 1) significant decrement of disc height (average 14%), 2) decreased disc motion of involved segment without hypermobility (average 34%), 3) hypermobility of adjacent segment, 4) and posterior facet overriding consistent with recurred low back pain.

Nontyphoidal Salmonella are gram negative bacilli organism, which may induce systemic infection such as febrile enteritis, bacteremia, and osteomyelitis. Main route of infection is known as food but also possible through reptile, amphibian, and fish raised as pets in the house. There is no known cases report of Salmonella infection through pets in Korea and also rare in the overseas. We report 2 patients who visited Severance children's hospital with chief complaint of fever and diagnosed as nontyphoidal salmonellosis. Each case had a history of raising turtle or tropical fish with possibility of Salmonella infection through these pets. Increasing incidence of raising pet reptile and fish lately, contact precaution and proper prevention and control of Salmonella infection of these pets especially in children under 5 years old are necessary due to higher risk of serious complications of salmonellosis.

PURPOSE: The aim of this study was to determine the frequency, epidemiology and the clinical manifestation of human metapneumovirus (hMPV) infection in Korean children. METHODS: From February 2010 to January 2012, we collected nasopharyngeal aspiration from 1,554 children who were hospitalized for acute lower respiratory tract infections at the Department of Pediatrics, Severance Children's Hospital. hMPV was detected by performing reverse transcriptase-polymerase chain reaction (RT-PCR). The medical records of the patients with positive results were retrospectively reviewed. RESULTS: We detected hMPV in 99 of the 1,554 hospitalized children. The mean age of the hMPV infected children was 25 months, and 87% of the illnesses occurred between April and June. The most common diagnoses were pneumonia (73%) and bronchiolitis (16%). The clinical manifestations included cough, fever, respiratory distress, hoarseness, tachypnea, and wheezing. Coinfection with other respiratory viruses was found in 43 children (43%). CONCLUSION: hMPV is one of the major virus causing acute respiratory tract infection in the age between 13 months and 48 months old with peaks during April to June. Reports of hMPV in Korea has been increasing but additional studies are required to define the epidemiology and the extent of disease caused by hMPV to determine future development of this illness in Korean children.

A 29-year-old woman complained of a painless, firm nodule with browunish patch on her left cheek for 5 months. She had had undergone a traffic accident 6 months before, and the normally healed wound on her cheek became reddish and infiltrated. A Skin biopsy specirinen obtained from her skin lesion showed a foreign body reaction with histiocytes and numerouse crystalline structures. These particle. were birefringent under polarized light microscopy. Scanning electron microscopy revealed numerous crystalline particles. Energy dispersive x-ray analysis of the crystal revealed a sharp peak representing silia.

PURPOSE: Human bocavirus (hBoV), a recently discovered virus, has been detected in children with respiratory tract infections worldwide. The aim of this study was to analyze the frequency and molecular phylogeny of hBoV in the respiratory samples of children with acute respiratory tract infections in 2010. METHODS: Nasopharyngeal samples were collected from 953 children with lower respiratory tract infections at Severance children's hospital in Korea from January 2010 to December 2010. We applied the multiplex PCR technique for the identification of 12 respiratory viruses from the samples. Among the total specimens, hBoV positive samples were subjected to phylogenetic analysis by sequencing a fragment of the VP1/VP2 gene junction. RESULTS: hBoV was detected in 141 (14.8%) among 953 patients. The 61.7% of hBoV-positive samples were found to co-exist with other respiratory viruses. The results of phylogenetic analysis showed that all 141 hBoV-positive isolates were identified as hBoV 1, revealing a high similarity among the isolates (>98%). CONCLUSION: hBoV 1 with minimal sequence variations circulated in children with acute respiratory infections during 2010. More research is needed to determine the clinical severity and outcomes of the minimal sequence variations.
