Spontaneously thrombosed cerebral arteriovenous malformations (AVM) are infrequently reported. Its pathophysiology, and natural course, however, are still not clarified yet. Authors report a case of symptomatic, spontaneously thrombosed cerebral AVM in a 34-year-old male with a follow-up of 16-year duration, which was surgically extirpated due to repeated bleeding and intractable seizure disorder, and histopathologically confirmed. Relevant literatures are reviewed and discussed.

PURPOSE: A relationship between Febrile seizure (FS) and iron deficiency anemia (IDA) has been found in several studies. However, few studies have focused on the role of IDA in complex febrile seizures (CFS) and simple febrile seizures (SFS) and there is no report on whether IDA is a risk factor for recurrence. The aim of this study was to investigate the role of IDA in SFS and CFS and to examine the effect of IDA on recurrence. METHODS: Patients (n=166) who had been diagnosed with FS were enrolled in our study. Subjects were divided into the following groups for analysis: the SFS and CFS groups, recurrence and non-recurrence groups. The onset age was compared in each group of patients and laboratory test results based on IDA were compared. RESULTS: Between the SFS and the CFS groups, there was no significant difference in laboratory test results based on IDA. There was a significant difference in onset age between the two groups and the onset age tended to be lower in the CFS group (24.00 vs. 16.49 months) (P=0.004). Comparing recurrence and non-recurrence groups, the mean corpuscular volume was significantly different (P=0.043) with the recurrence group having a lower mean corpuscular volume level (78.92 vs. 77.48). The onset age in the recurrence group was lower (26.02 vs. 19.68 months). CONCLUSION: This study suggests that onset age could be a risk factor for CFS, and IDA may not contribute to elevating the risk of CFS. However, IDA may play an important role in the recurrence of FS.

PURPOSE:
Growth and development of infants can be periodically assessed through health screening, but iron deficiency anemia, which is common in infants, is difficult to detect by conducting only infant health screening. This study evaluated the prevalence of iron deficiency anemia in infants who visited Chung-Ang university hospital between 9 and 12 months of age. The study also determined the difference of anemia between term and preterm infants.
METHODS:
The subjects of this study were infants aged 9 to 12 months who visited outpatient clinics of Chung-Ang University Hospital from January 2006 to August 2018 for the purpose of infant health screening and immunizations. We divided the subjects as the term group and the preterm group, and their medical records were retrospectively analyzed.
RESULTS:
One hundred and fifty-two infants were included in the study. There were 51 in the preterm infant group and 101 in the term infant group. Thirteen infants were diagnosed with iron deficiency anemia, and 12 infants of these infants were in the term group and one infant was in the preterm group, which was statistically significant (P<0.001). There are significant differences in the hemoglobin (12.0±1.1 g/dL, 12.6±1.2 g/dL), hematocrit (35.8%±2.7%, 36.7%±3.2%), serum iron (60.8±25.4 µg/dL, 73.5±40.9 µg/dL), and unsaturated iron binding capacity (279.1±67.7 µg/dL, 252.0±47.5 µg/dL) between the term infant group and the preterm infant group, respectively (P<0.05).
CONCLUSION
Iron deficiency anemia was significantly more often diagnosed in term infants than that in preterm infants. Preterm infants may have a lower prevalence of iron deficiency anemia than do term infants because the preterm infants are taking iron supplements prophylactically. Therefore, iron deficiency anemia should be prevented in term infants, and it is important to confirm the presence of iron deficiency anemia by conducting blood tests during the first 9 to 12 months of life.

Adequate organ growth is an important aspect of growth evaluation in children. Renal size is an important indicator of adequate renal growth; computed tomography (CT) can closely estimate actual kidney size. However, insufficient data are available on normal renal size as measured by CT. This study aimed to evaluate the relationships of anthropometric indices with renal length and volume measured by CT in Korean pediatric patients. Renal length and volume were measured using CT images in 272 pediatric patients (age < 18 years) without renal disease. Data for anthropometric indices—including height, weight, and body surface area (BSA)—were obtained using medical records. Using the equation for an ellipsoid, renal volume was calculated in cubic centimeters. Height showed greatest correlation with renal length on stepwise multiple linear regression analysis; BSA showed the strongest significant correlation with renal volume. The mean renal size for each age group and height group was determined; it showed a tendency to increase with age and height. This is the first Korean study to report the relationship between body indices and renal size measured by CT. These results can serve as normative standards for assessing adequate renal growth.

Although central catheter-related complications are frequently reported and are inevitable in the neonatal care unit, the incidence of pericardiac tamponade is low but may be fatal. Index of suspicion, prompt diagnosis, and urgent pericardiocentesis are crucial for lifesaving. We encountered two premature cases of central venous catheter-related pericardial tamponade. The first case was a 4-day-old male premature infant (gestational age [GA], 33(+5) weeks; birth weight [BW], 1,864 g), and the second case was a 4-day-old female premature infant (GA, 28(+6) week; BW, 1,050 g). Each infant had an indwelling central venous catheter since birth and at the third day of hospitalization. The conditions of the babies suddenly deteriorated, but both babies were successfully resuscitated with urgent echocardiography and prompt pericardiocentesis.

PURPOSE: Anti-insulin antibodies develop within several months of initiation of insulin therapy in most of diabetic patients. The purpose of this study is to observe the relationship between the clinical factors and development of anti-insulin antibody METHODS: Serum was collected from 116 diabetic patients and 47 nondiabetic children for the measurement of anti-insulin antibody titer by radioimmunoassay (RIA). Retrospective analysis of the medical records of clinical factors were evaluated. RESULTS: There was no relationship of anti-insulin antibody titer with age, duration, HbA1c, insulin dose, and BMI in diabetic children. There was no difference in anti-insulin antibody titer according to the sex, the presence of family history, the presence of DKA, the presence of complications, the presence of puberty, species of insulin, duration of disease in diabetic children. The titers of anti-insulin antibody were significantly higher in type 1 diabetic children(30.3+/-17.9% in type 1 and 16.5+/-7.0% in type 2, P<0.05), in which the daily insulin doses were significantly higher than in type 2 DM patients. Additionally, anti-insulin antibody titers were significantly lower in well-controlled DM patients (HbA1c<7%), in which daily insulin doses also were significantly lower than in DM patients whose HbA1c>7%. The positive rates of anti-insulin antibody were higher in male patients with diabetes(73.2% in male and 53.3% in female, P<0.05). The positive rates of anti-insulin antibody were significantly higher in DM patients without diabetic ketoacidosis at DM onset than in DM patients with diabetic ketoacidosis at DM onset & also were higher in poorly-controlled group(HbA1c>7%). CONCLUSION: The results suggests that anti-insulin antibody developed more likely in type 1 DM and less likely in DM patients whose control had been good and who used less insulin doses, which remains to be studied further with more patients for longer duation.

BACKGROUND: The detection of total anti-hepatitis A virus (anti-HAV) immunoglobulin (Ig) and IgM is important for diagnosing acute hepatitis A. Our laboratory introduced new commercial automated chemiluminescence immunoassays (CLIAs) for use in addition to pre-existing automated CLIA. We evaluated the rate of agreement in the detection of total anti-HAV Ig and IgM in serum samples between two automated CLIAs. METHODS: We analyzed 181 samples those were submitted for testing at Kangbuk Samsung Medical Center. We analyzed the rate of agreement between the ADVIA Centaur XP (Siemens, Germany) and the MODULAR ANALYTICS E170 (Roche, Switzerland) analyzers. We performed reverse transcription (RT)-PCR when there was a discrepancy between the results from the two analyzers. RESULTS: The agreement rates between the ADVIA Centaur XP and the MODULAR ANALYTICS E170 for total anti-HAV Ig and IgM were 97.2% and 98.9%, respectively. Discrepant results were obtained in seven cases; all were found to be HAV-negative based on RT-PCR analysis. CONCLUSIONS: The total anti-HAV Ig and IgM results obtained using the two automated analyzers were comparable. However, in cases of equivocal results tested by the ADVIA Centaur XP for anti-HAV IgM, retesting and follow-up testing of samples are recommended.

BACKGROUND: Although the broth microdilution method has been recently established for antifungal susceptibility testing of the Candida species, there is still an argue in the interpretation of the trailing endpoint. We evaluated the spectrophotometric broth microdilution method (SBM) to determine the fluconazole MICs from five different Candida species. METHODS: A total of 252 clinical isolates of five Candida species (144 C. albicans, 42 C. tropicalis, 32 C. glabrata, 28 C. parapsilosis, and 6 C. krusei) were tested for fluconazole susceptibility with the broth microdilution method. The MICs were spectrophotometrically determined at 80% (Spec-80%) and 50% (Spec-50%) decrease in absorbance as compared with growth control, respectively. The results were compared with the fluconazole MICs tested by the National Committee for the Clinical Laboratory Standards (NCCLS) macrodilution method. RESULTS: When MICs were obtained by Spec-80%, the agreements of SBM and the NCCLS macro dilution method within two doubling dilutions were 92.4% (220/238) at 24 h and 78.6% (198/252) at 48 h for all Candida species. Using the Spec-50%, those were increased to 97.9% (233/238) at 24 h and 98.8% (249/252) at 48 h (P<0.01). Especially, for C. albicans and C. tropicalis, the agreement of the Spec-50% was significantly higher than those of the Spec-80% at 48 h; 97.9% vs. 75.0%, for C. albicans (P<0.01), and 100% vs. 57.1%, for C. tropicalis (P<0.01). CONCLUSIONS: These data suggest that the SBM using Spec-50% can provide a more precise and objective mean for fluconazole susceptibility testing, especially for C. albicans and C. tropicalis.
