Trisomy 18 is the second most common chromosomal anomaly that reach to live birth after Down syndrome. Several methods were proposed to screen patients on the risk of Edward syndrome like maternal serum levels using total human chorionic gonadotropin (hCG), alpha-fetoprotein (AFP) and unconjugated estriol (uE3), or free beta hCG with AFP, but the serum screening has only 50-60% detection rate with a 1-2% of false positive rate. So to cover the limitations that serum marker has, detailed ultrasound examination is also necessary and sensitivities of 65-70% were reported. We report a case of trisomy 18 fetus in which second trimester triple markers of maternal serum was normal, but by detailed ultrasound examination, unilateral radius aplasia was diagnosed cytogenetic study confirmed the fetus as trisomy 18.

PURPOSE: Febrile convulsions are classified into simple or complex types, the latter being characterized by increased risk of recurrence and progression to epilepsy. This study aimed to delineate the clinical characteristics of complex febrile convulsions. METHODS: Between January 2003 and December 2006, 550 children were diagnosed with febrile convulsions at the Department of Pediatrics, Ilsan Paik Hospital. Their medical records were retrospectively reviewed for comparison between simple and complex febrile convulsions, and clinical findings of complex febrile convulsions were clarified. RESULTS: Our subjects comprised a male-to-female ratio of 1.64:1; the age range was from 8 months to 8 years. Simple febrile convulsions comprised 432 cases, i.e., 4 times as many as complex febrile convulsions (118 cases). The causes of febrile illness included acute pharyngotonsillitis (357 cases, 64.9%), pneumonia (55 cases, 10.0%), acute gastroenteritis (37 cases, 6.7%), and otitis media (20 cases, 3.6%). We did not find any significant difference between simple and complex febrile convulsions in most clinical parameters such as gender, age, family history of febrile convulsions, and cause of febrile illness. Regarding subtypes of complex febrile convulsions, repeated convulsions were the most frequent (72.0%), followed by prolonged convulsions (16.9%) and focal convulsions (5.1%). CONCLUSION: We have reported here the clinical features of complex febrile convulsions. Although the results did not show any significant difference between simple and complex febrile convulsions in most clinical parameters such as gender, age, family history of febrile convulsion, and cause of febrile illness, further studies are essential to delineate complex febrile convulsions.

BACKGROUND: About more than 70% of Staphylococcus aureus isolates in tertiary-care hospitals are known to be resistant to methicillin in Korea. But the prevalence of methicillin-resistant S. aureus (MRSA) in the community and non-tertiary hospitals has not been known yet. The aim of this study was to determine the prevalence of resistance among S. aureus isolates in non-tertiary hospitals. METHODS: The isolates were collected at one laboratory center from August 1998 to May 1999. Antimicrobial susceptibility tests against 11 antibiotics were performed by disk diffusion method. Minimum inhibitory concentrations (MIC) for oxacillin and vancomycin were determined by microbroth dilution method. The mecA gene was detected by polymerase chain reaction. The medical facilities which sent specimen to the laboratory were classified into 3 groups; clinic, hospital and general hospital. RESULTS: Of total 469 S. aureus isolates, 296 (63.1%) were from pus, 47 (10.0%) from sputum, 23 (5.0%) from urine, and 22 (4.6%) from blood. Overall prevalence of MRSA in non-tertiary hospital was 43.5% (204/469). Among 3 hospital groups, MRSA in general hospitals (55%) was significantly more prevalent than in hospitals (40%) or clinics (37%). MICs of oxacillin against MRSA isolated from pus and blood ranged from 8 to > or =256 microgram/mL, but 74% (83 isolates) of them was > or =256 microgram/mL. MICs of vancomycin were distributed from 1 to 2 microgram/mL, irrespective of methicillin resistance or hospital groups. The mecA gene was detected in all of methicillin-resistant isolates with MICs of < or =128 microgram/mL. CONCLUSION: In non-tertiary hospitals, 43% of S. aureus isolates were methicillin resistant. This result showed that MRSA in non-tertary hospitals was less prevalent than in tertiary hospitals.

BACKGROUND: The ocular adnexal extranodal marginal zone B-cell lymphoma has been known as the 2nd most common extranodal marginal zone B-cell lymphoma, which presents as the dermatologic symptom and sign, such as orbital mass and swelling. However, the ocular adnexal extranodal marginal zone B-cell lymphoma has been few reported in the dermatologic literature. OBJECTIVE: We described the clinical and histopathological features of ocular adnexal extranodal marginal zone B-cell lymphoma from the perspective of dermatology. METHODS: Ninety-nine cases of ocular adnexal extranodal marginal zone B-cell lymphoma patients were included in this study, among the 352 patients, who were diagnosed with extranodal marginal zone B-cell lymphoma between March 1998 and February 2011. Their medical records and histopathologic slides were retrospectively reviewed. RESULTS: Among the 352 patient of extranodal marginal zone B-cell lymphoma, ocular adnexal extranodal marginal zone B-cell lymphoma occurred in 99 patients (28.1%). The ratio between male and female was 1:2, and the mean age was 50 years (range; 20~54 years). Ocular adnexal extranodal marginal zone B-cell lymphoma presented as orbital mass (39.1%), conjunctival injection (25.6%), orbital swelling (19.5%), and etc. In most patients, lesions were located in conjunctiva (63.8%) or orbit (14.5%). 76.7% of patients presented with Ann Arbor stage I disease. Relapses occurred in 8.4% of patients during the follow-up period. CONCLUSION: When dermatologists meet patients presenting with orbital mass and swelling, dermatologists consider the possibility of ocular adnexal extranodal marginal zone B-cell lymphoma and consultation with the ophthalmologists.

OBJECTIVE: To evaluate the invasive capacity of trophoblastic cells when treated with HGF, and see whether HGF induces c-met expression in vitro. METHODS: HT cell line was treated with recombinant HGF (rHGF) at different concentrations (0, 10, 50 and 100 ng/mL) and cultured for 24 hours. To evaluate according different time of culture, HT cell line was pre-treated with 50 ng/mL rHGF and cultured for 24, 36, 48 and 72 hours. We analyzed the expression of c-met mRNA using reverse transcriptase-polymerase chain reaction and the expression of c-met protein using western blot in each samples. We also observed cellular invasion capacity through the invasion assay under a microscope and confirmed 72 kDa gelatinase and 92 kDa gelatinase expression patterns by zymography assay. RESULTS: The expressions of c-met mRNA and protein were increased in all concentrations of rHGF, compared with that of normal control although it was not in dose-dependent fashion. In invasion assay, the number of invaded HT cells were increased in dose-dependent fashion, compared with that of normal control. In zymography ssay, the expression of 72 kDa gelatinase was increased in dose-dependent fashion, compared with the control. However, 92 kDa eglatinase was not detected in any studied group. CONCLUSION: These results suggests that HGF might be related to upregulation of trophoblast cell invasiveness by activation of c-met and subsequent induction of 72 kDa gelatinase.
