PURPOSE: Cerebral cortical dysplasias are one of the important causes for epileptic seizures and developmental disabilities in children, particularly in diffuse or bilateral cases. These developmental malformations are generally regarded as a group of neuronal migration disorders, however, the classification system and pathogenetic mechanisms of cortical dysplasias are not yet entirely clear. Even a novel entity, congenital bilateral perisylvian syndrome, characterized by speech delay, pseudobulbar Palsy, intractable seizures, and bilateral perisylvian abnormalities on imaging studies, have rather diverse figures on morphology and symptomatology than initially considered. We have studied the clinical features and correlations of clinical outcomes 3nd magnetic resonance imaging(MRI) findings of bilaterally involved cortical dysplasias. METHODS: 20 cases of bilateral cortical dyspalsias were grouped into three categories on the basis of MRI findings; centroparietal dysplasias(6 cases), diffuse dysplasias with (5) or without white matter lesions(4), and schizencephaly(5). EEGs, motor and language development, epilepsy, and outcomes were reviewed in each groups. RESULTS: Language delay(100%), motor developmental delay(94.7%), motor deficit(65%), epilepsy(40%) were the main reasons for their initial hospital visits. A meaningful word expression was possible at the mean age of 2 years and 2 months(1 to 4 years of age). Hypotonia and spastic motor paralysis were evident in all the cases of diffuse dysplasia with white matter lesions and the schizencephaly groups. All but one case of centroparietal dysplasia showed motor developmental delay. Epilepsies were developed in 8 cases at the mean age of 5 years and 5 months(2 months to 12 years of age) and the seizures were relatively well controlled with anticonvulsants. EEG findings were variable; normal, focal or diffuse abnormalities. High amplitude diffuse fast activities were only noted in the diffuse dysplasia group. CONCLUSION: The severity of neurological deficits and developmental delay had correlated to the size of cortical abnormalities. The epilepsies were relatively well controlled during childhood and the EEG finding of high amplitude diffuse fast activities was specific for the diffuse cortical dysplasias. Bilateral centroparietal dysplasias should be included on consideration of the causes for developmental aphasia.

Background: Burnout is a syndrome resulting from chronic work-related stress, characterized by symptoms including “feelings of exhaustion, increased mental distance from one’s job, and reduced professional efficacy.” Human service providers are susceptible to burnout. Thus, this study aimed to investigate community mental health workers’ job stress, experiences with client violence, and burnouts and to analyze factors that affect burnout. Methods: This study used retrospective data from a survey of mental health workers at a mental health-related institution in a city. The data included sociodemographic characteristics, job stress, client violence, and quality of life. Results: From a total of 170 mental health workers, 67.6% were female. Subjects who were in lower age groups, had <1 year of work experience, were married, and were irregular workers were vulnerable to various job stressors. Factors associated with burnout were job demand, lack of reward, job insecurity, physical environment, other violence, and level of education. Conclusion We should create an environment wherein community mental health workers can be safe and satisfied with their work, which could lower workers’ job stress and prevent burnouts due to work. This, in turn, enhances the quality of care provided to people with mental health problems.

PURPOSE: To assess the clinical features and laboratory findings in Kawasaki patients with nonresponsibility to the acute antiinflammatory treatment, and identify the risk factors for the nonresponsibility, we reviewed the medical records of patients with Kawasaki disease. METHODS: A retrospective study of 177 patients with Kawasaki disease at Wonkwang University Medical Center from June, 1997 to June, 2002, was performed. High dose intravenous immune globulin(IVIG) and aspirin were all used for the initial acute antiinflammatory treatment. Two groups, group A(n=19) of initial nonresponders and group B(n=158) of initial responders were compared clinically and laboratorically. RESULTS: Nineteen(10.7%) of 177 patients hardly responded to the initial antiinflammatory treatment. Patients with failure to respond to initial treatment(group A) did not differ from the control group in terms of age, sex, WBC count, coronary abnormalities, and evidence of pyuria. Compared with initial responders(group B), the patients who were retreated(group A) had a significantly shorter fever- admission interval(P=0.041), and a higher level of both AST/ALT(P=0.011) and ASO titier(P=0.000). CONCLUSION: Among Kawasaki disease patients studied, retreatment group with initial nonresponders had significantly shorter fever-admission interval, and higher both AST/ALT level and ASO titer, than the initial response group.

PURPOSE: The aim of this retrospective study was to evaluate cumulative survival rate (CSR) of Implantium implants followed for 5 years and association between risk factors and the CSR. MATERIALS AND METHODS: A total of two hundred forty-nine Implantium Implants System (Dentium, Seoul, Korea) placed in ninety-five patients from 2004 to 2009 were investigated with several identified risk factors (sex, systemic disease, smoking, alchohol, reason of tooth loss, length, arch (maxilla or mandible), replace tooth type (incisor, canine, premolar or molar) Kennedy classification, prosthodontic type, prosthodontic design, opposite dentition, abutment type, occlusal material, occlusal unit, splint to tooth, cantilever, other surgery). Clinical examination (mobility, percussion, screw loosening, discomfort, etc.) and radiographic examination data were collected from patient records including all problems during follow-up period according to protocols described earlier. Life table analysis was undertaken to examine the CSR. Cox regression method was conducted to assess the association between potential risk factors and overall CSR. RESULTS: Five of 249 implants were failed. Four of these were lost before loading. The 5-year implant cumulative survival rate was 97.37%. Cox regression analysis demonstrated a significant predictive association between overall CSR and systemic disease, smoking, reason of tooth loss, arch, Kennedy classification and prosthodontic design (P<.05). The screw related complication was rare. Two abutment screw fractures were found. Another complications of prosthetic components were porcelain fracture, resin facing fracture and denture fracture (n=19). CONCLUSION: The 5-year CSR of Implantium implants was 97.37%. Implant survival may be dependent upon systemic disease, smoking reason of tooth loss, arch, Kennedy classification and prosthodontic design (P<.05). The presence of systemic diseases and combination of other surgical procedures may be associated with increased implant failure.

We investigated the seroepidemiological, clinical, and laboratory characteristics of patients suspected to have toxocariasis in Gwangju and Jeonnam-province, Korea. In total, 228 specimens were analyzed for anti-Toxocara canis IgG at two university hospitals from 2010 to 2012. The overall seropositive rate was 67.1%, and the seropositive rates among the eosinophilic and non-eosinophilic groups were 76.1% (105/138) and 53.3% (48/90), respectively. Risk factors for eosinophilia and toxocariasis were male sex (odds ratios [OR]=2.632 and 3.477, respectively) and a history of ingesting raw meat (OR=2.884 and 3.274, respectively), especially raw cow liver (OR=2.089 and 10.038, respectively). T. canis seropositivity (OR=5.807, P=0.004) and a history of consuming raw cow liver (OR=2.766, P=0.052) were risk factors for organ involvement. The anti-T. canis IgG level showed weakly positive correlations with eosinophil counts (r=0.234, P<0.001) and the duration of eosinophilia (r=0.155, P=0.019). Although limited to the regions of Gwangju and Jeonnam-province, this study supports the opinion that toxocariasis is a reasonable focus as a cause of eosinophilia and that it is also associated with organ involvement.

An 11-year-old girl was diagnosed with encephalitis due to Epstein-Barr virus(EBV). She was admitted to our hospital due to convulsion and decreased consciousness after several days of fever, sore throat and headache. Cerebrospinal fluid analysis showed lymphocyte-dominant pleocytosis and markedly elevated levels of protein. Magnetic resonance imaging(MRI) finding was normal, except for marked leptomeningeal enhancement. Even though she had signs and symptoms of infectious mononucleosis, EBV infection could not be considered as the underlying cause of the encephalitis until IgM for the viral capsid antigen of EBV had been detected in her blood. After treatment with acyclovir, a high dose of methylprednisolone and intravenous immunoglobulin, the neurological symptoms improved rapidly. She has not suffered from any neurological complications in the four months since being discharged. EBV infection should be considered as the main etiology in cases of childhood encephalitis, although there is no evidence of infectious mononucleosis existed.

The development of renal glomerular lesions secondary to severe visceral infection (pulmonary, pleural, retroperitoneal or hepatic abscess) is not generally appreciated. Such patients resemble those with infective endocarditis. The suggested pathogenetic mechanisms by which infection can cause glomerular damage are immunologic interaction, direct toxicity of a bacterial products, and some other triggering factors; However, direct correlation between the infectious and immunologic events has not been demonstrated. The histopathologic findings of infectious glomerulonephritis are variable, and these findings, as well as the clinical abnormalities, may resolve with effective antimicrobial therapy or abscess drainage. We experienced a case of glomerulonephritis and acute renal failure due to staphylococcal retroperitoneal abscess. The patient was a 58-year-old man who presented with abdominal and back pain. We performed an abdominal CT scan which showed a retroperitoneal abscess which was proven to be a staphylococcal infection upon percutaneous abscess drainage. Furthermore, we performed a renal biopsy in order to investigate hematuria, RBC casts, and proteinuria. Pathologic findings revealed postinfectious glomerulonephritis. Abscess drainage and sensitive antibiotics were administered, after which his symptoms and urinary abnormalities disappeared, and the retroperitoneal abscess subsided. Here, we report a case of a staphylococcal retroperitoneal abscess which led to postinfectious glomerulonephritis and acute renal failure along with a brief review of the literatures.

We report a rare case of fungemia due to Exophiala (Wangiella) dermatitidis in a 4-month-old female infant who was admitted to an intensive care unit with sudden infant death syndrome (SIDS). E. dermatitidiswas repeatedly isolated from blood cultures (on the 28th and 32nd day of hospitalization) of the patient, who died on the 44th day of hospitalization. The fungus was identified by its morphological characteristics and DNA sequencing of both the D1/D2 domain and the ITS region of rDNA. To our knowledge, this is the first reported case of E. dermatitidis fungemia in Korea.

BACKGROUND: The incidence of Bacillus cereus bacteremia is increasing, but the identification of Bacillus species remains difficult. Brilliance Bacillus cereus agar (BBC agar; Oxoid, UK) is a new CHROMagar medium that allows selective isolation and identification of B. cereus; however, its clinical usefulness is seldom studied. We evaluated the usefulness of BBC agar to identify B. cereus isolates recovered from blood cultures. METHODS: We analyzed a total of 53 blood isolates that showed a Bacillus-like morphology on Gram staining. All isolates were identified by using both the API Coryne (bioMerieux, France) and API 50CH/B (bioMerieux) systems. They were subsequently subcultured on BBC agar, incubated for 24 hr, and then examined for characteristic blue-green colonies. The clinical characteristics of patients whose isolates were identified as B. cereus were assessed. RESULTS: Of the 53 isolates, 18 were identified as B. cereus by API 50CH/B. With the API 50CH/B system used as gold standard, the sensitivity and specificity for the identification of B. cereus were 100% (18/18) and 100% (35/35), respectively, using BBC agar, and 67% (12/18) and 100% (35/35), respectively, using the API Coryne system. Of the 18 patients with B. cereus bacteremia, 15 showed infectious signs, and 3 had more than 2 blood cultures positive for B. cereus on separate days. CONCLUSIONS: Our study shows, for the first time, that BBC agar, with its good agreement and ease of use, is a valuable alternative to the API 50CH/B system for the presumptive identification of B. cereus isolates from blood cultures.
