Objectives: This study examined the association between the dietary behavior and weight status of preschool children and their mothers in Daejeon, Korea. Methods: A total of 301 mother–preschool children (aged 3~6 years) dyads were included in this study. The dietary behavior of children and their mothers was assessed using the Nutrition Quotient (NQ) questionnaire for preschoolers and adults, respectively. The NQ questionnaires were completed by the mothers. The overweight/ obesity status of children and their mothers was determined using data on height and body weight reported by the mothers. Multiple logistic regression was performed to examine the relationship between the dietary behavior and weight status of children and their mothers. Results: The mean NQ score was 58.9 ± 9.7 in children and 55.6 ± 9.2 in mothers. The NQ score was higher in boys than girls but did not vary by age. The prevalence of overweight/obesity was 27.5% in children and 46.5% in mothers. The physical activity level of mothers and their NQ scores were positively associated with the NQ scores of the children. After adjustment for covariates, the mothers in the highest tertile of NQ scores showed a lower odds ratio (OR) for the unhealthy dietary behavior of children (OR = 0.24, 95% CI = 0.11~0.53, P< 0.001) compared to those in the lowest tertile.The obese mothers showed a higher OR for children’s overweight/obesity (OR = 3.38, 95% CI = 1.68~6.80, P = 0.001) compared to normal weight mothers. Conclusions The dietary behavior and weight status of young children and their mothers were closely linked. Nutrition education programs targeting mothers are necessary for improving maternal and child nutrition. Specifically, these programs need to be tailored to the socioeconomic characteristics or weight status of mothers.

PURPOSE: To report a patient with Coats' disease who presented with a premacular membrane that was peeled off after laser photocoagulation. CASE SUMMARY: A 17-year-old male presented with decreased visual acuity of the right eye, and showed serous elevation, subretinal hemorrhage, telangiectasis and thick premacular membrane upon fundus examination. Upon diagnosis with Coats' disease, the telangiectatic area was treated with argon laser photocoagulation. Two weeks later, the premacular membrane was peeled off spontaneously and the decrease of macular thickness was verified by optical coherence tomography (OCT). The patient's visual acuity was improved to 1.0. CONCLUSIONS: The visual acuity of the patient with Coats' disease was improved by spontaneous peeling of the premacular membrane after photocoagulation.

OBJECTIVE: To evaluate the feasibility of coronary artery calcium scoring based on three virtual noncontrast-enhanced (VNC) images derived from single-source spectral dual-energy CT (DECT) as compared with true noncontrast-enhanced (TNC) images. MATERIALS AND METHODS: This prospective study was conducted with the approval of our Institutional Review Board. Ninety-seven patients underwent noncontrast CT followed by contrast-enhanced chest CT using single-source spectral DECT. Iodine eliminated VNC images were reconstructed using two kinds of 2-material decomposition algorithms (material density iodine-water pair [MDW], material density iodine-calcium pair [MDC]) and a material suppressed algorithm (material suppressed iodine [MSI]). Two readers independently quantified calcium on VNC and TNC images. The Spearman correlation coefficient test and Bland-Altman method were used for statistical analyses. RESULTS: Coronary artery calcium scores from all three VNC images showed excellent correlation with those from the TNC images (Spearman's correlation coefficient [ρ] = 0.94, 0.88, and 0.89 for MDW, MDC, and MSI, respectively; p < 0.001 for all pairs). Measured coronary calcium volumes from VNC images also correlated well with those from TNC images (ρ = 0.92, 0.87, and 0.91 for MDW, MDC, and MSI, respectively; p < 0.001 for all pairs). Among the three VNC images, coronary calcium from MDW correlated best with that from TNC. The coronary artery calcium scores and volumes were significantly lower from the VNC images than from the TNC images (p < 0.001 for all pairs). CONCLUSION: The use of VNC images from contrast-enhanced CT using dual-energy material decomposition/suppression is feasible for coronary calcium scoring. The absolute value from VNC tends to be smaller than that from TNC.

PURPOSE: To identify altered patterns of retinal mRNA expression in a rat model of oxygen-induced retinopathy (OIR). METHODS: Sprague-Dawley rats from P2 to P14 were exposed to hyperoxia (80% oxygen) to induce OIR and then returned to normoxic conditions. Control rats were sustained in room air. Retinal gene expression between the rats of OIR and the controls was compared using cDNA microarray analysis. Reverse transcriptase polymerase chain reaction (RT-PCR) was used to verify the microarray results. RESULTS: Among a total of 12,731 cDNAs analyzed by mircroarray, 13 genes were strongly up- or down-regulated (>2-fold change over controls) in the OIR rats. We found a significant increase in expression of 10 genes (CaM-kinase II inhibitor; acidic nuclear phosphoprotein 32 family, member A; vascular endothelial growth factor; interferon alpha-inducible protein 27-like; similar to enthoprotin, epsin 4, clathrin interacting protein; nidogen [entactin]; tubulin, beta5; fibrillin-1; spectrin beta2; and stearoyl-coenzyme A desaturase 2) and a significant decrease in expression of 3 genes (myelin-associated oligodendrocytic basic protein, heat shock protein, and decorin) in OIR rats compared to controls. CONCLUSIONS: We confirmed changes in expressions of various retinal genes in a rat model of OIR by microarray and RT-PCR. This study should contribute to the understanding of genetic indicators associeated with OIR.

OBJECTIVE: The aim of this study was to identify the morphological and functional characteristics of quadricuspid aortic valves (QAV) on cardiac computed tomography (CCT). MATERIALS AND METHODS: We retrospectively enrolled 11 patients with QAV. All patients underwent CCT and transthoracic echocardiography (TTE), and 7 patients underwent cardiovascular magnetic resonance (CMR). The presence and classification of QAV assessed by CCT was compared with that of TTE and intraoperative findings. The regurgitant orifice area (ROA) measured by CCT was compared with severity of aortic regurgitation (AR) by TTE and the regurgitant fraction (RF) by CMR. RESULTS: All of the patients had AR; 9 had pure AR, 1 had combined aortic stenosis and regurgitation, and 1 had combined subaortic stenosis and regurgitation. Two patients had a subaortic fibrotic membrane and 1 of them showed a subaortic stenosis. One QAV was misdiagnosed as tricuspid aortic valve on TTE. In accordance with the Hurwitz and Robert's classification, consensus was reached on the QAV classification between the CCT and TTE findings in 7 of 10 patients. The patients were classified as type A (n = 1), type B (n = 3), type C (n = 1), type D (n = 4), and type F (n = 2) on CCT. A very high correlation existed between ROA by CCT and RF by CMR (r = 0.99) but a good correlation existed between ROA by CCT and regurgitant severity by TTE (r = 0.62). CONCLUSION: Cardiac computed tomography provides comprehensive anatomical and functional information about the QAV.

OBJECTIVE: To compare the diagnostic performance of electrocardiogram (ECG)-gated thoracic computed tomography angiography (TCTA) without heart rate (HR) control in ischemic stroke patients with coronary CTA (CCTA) in non-stroke patients for detection of significant coronary artery stenosis. MATERIALS AND METHODS: From September 2009 through August 2014, we retrospectively enrolled 138 consecutive patients diagnosed with acute ischemic stroke who had undergone ECG-gated TCTA and conventional coronary angiography (CCA). Over the same period, we selected 167 non-stroke patients with suspected or known coronary artery disease who had undergone CCTA and CCA. With CCA as the reference standard, the diagnostic performance of TCTA and CCTA for identification of significant coronary stenosis (diameter reduction ≥ 50%) was calculated. RESULTS: There was no significant difference in baseline characteristics between TCTA (n = 132) and CCTA (n = 164), except for the higher prevalence of atrial fibrillation in the stroke group. There was significant difference (p < 0.001) between TCTA and CCTA in average HR (68 ± 12 vs. 61 ± 10 beats per minute) and image quality score (1.3 ± 0.6 vs. 1.2 ± 0.6). Significant coronary stenosis was identified in 101 (77%) patients, 179 (45%) vessels, and 293 (15%) segments of stroke patients, and in 136 (83%) patients, 259 (53%) vessels, and 404 (16%) segments of non-stroke patients. Diagnostic performance on a per-vessel and per-patient basis was similar in both TCTA and CCTA groups. There was only significant difference in area under receiver-operating characteristic curve between TCTA and CCTA groups (0.79 vs. 0.87, p < 0.001) on per-segment basis. CONCLUSION: Electrocardiogram-gated TCTA without HR control facilitates the identification of significant coronary stenosis in patients with ischemic stroke.

Hemicrania continua (HC) is an indomethacin-responsive primary headache. Owing to continuous unilateral headache and clinical rarity, a great attention should be paid during the diagnosis of HC to exclude secondary causes of headache. Various pathologies have been described for HC-like headache. We describe a 64-year old man with invasive sphenoid sinus aspergillosis who presented continuous unilateral headache, trigeminal autonomic symptoms and response to oral indomethacin 225 mg/day. He was treated with intranasal ethmoidectomy and antifungal agent, and his headache has greatly improved.
