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.

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.

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 most of pseudocysts as one of complications of pancreatitis occur primarily within the pancreas, the extrapancreatic locations of pseudocysts, especially in the liver, are rare events. With advanced technology of imaging studies including abdominal computed tomography, ultrasonography, and magnetic resonance imaging, their frequency seems to be increasing. We report here a case of left intrahepatic pancreatic pseudocyst following acute pancreatitis. Percutaneous puncture revealed a high level of amylase and lipase in the collection, confirming the diagnosis of intrahepatic pseudocyst. Symptomatic intrahepatic pseudocysts can be managed surgically, transcutaneously or endoscopically, and asymptomatic intrahepatic pseudocysts can be treated conservatively. We report this case with a review of literature.

BACKGROUND: Sentinel lymph node (SLN) mapping of the stomach cancer using available techniques is limited by unpredictable lymphatic drainage patterns and skip metastasis. The aim of this study was to test the feasibility of gastric SLN mapping using fluorescent magnetic nanoparticles (FMNP) of uniform nano-size. METHODS: Biocompatible silica-overcoated magnetic nanoparticles containing rhodamine B isothiocyanate (RITC) within a silica shell of controllable thickness with 60 nm thickness were used as model nanomaterials. Gastric lymphatic mapping was performed by injecting 100 microliter of either FMNP or isosulafan blue subserosally. Gastric injections (n=7) were made into the body, approximately 5 cm from the lesser curvature of rabbits. Sentinel lymph nodes were visualized using fluorescent nanoparticle detection system. RESULTS: In 7 rabbits, it was demonstrated that FMNP quickly and accurately detected sentinel lymph nodes. Injection into the stomach resulted in identification of a retrogastric lymph node. Histological analysis in all cases confirmed the presence of nodal tissue. CONCLUSIONS: FMNP can be a potential alternative to existing tracers in the detection of SLN in this animal experiment.

Methicillin-resistant Staphylococcus aureus (MRSA) is a critical source of infections in neonatal intensive care units. Early diagnosis and treatment are important due to the significant morbidity of MRSA infection. MRSA sepsis can be disseminated despite antibiotics, therefore the extent of the infection should be evaluated. Common complications of MRSA sepsis include infective endocarditis, pneumonia, osteomyelitis, meningitis, septic shock.Urgent evaluation of other possible suppurative complications in neoate are necessary. Therefore echocardiogram, chest X-ray, ophthalmic examination, brain sonography and spinal tapping are needed. In this study, we present a case of MRSA sepsis in a preterm infant, accompanied by endophthalmitis and endocarditis in spite of the early diagnosis and treatment.
