OBJECTIVE:To evaluate the biodurability of the covering material in retrievable metallic stents covered with polycarbonate polyurethane. MATERIALS AND METHODS: Using a peristaltic pump at a constant rate of 1ml/min, bile was recirculated from a reservoir through a long tube containing four stents. Each of these was removed from the system every two weeks and a radial tensile strength test and scanning electron microscopy (SEM) were performed. Each stent, removed at 2, 4, 6 and 8 weeks, was compared with a control stent not exposed to bile juice. RESULTS: Gross examination showed that stents were intact at 2 weeks, but at 4, 6 and 8 weeks cracks were observed. The size of these increased gradually in accordance with the duration of exposure, and at 8 weeks several large holes in the polyurethane membrane were evident. With regard to radial tensile strength, extension and peak load at break were 84.47% and 10.030 N/mm, 54.90% and 6.769 N/mm, 16.55% and 2.452 N/mm, 11.21% and 1.373 N/mm at 0, 2, 4 and 6 weeks, respectively. Scanning electron microscopy at 2 weeks revealed intermittent pitting and cracking, and examination at 4, 6 and 8 weeks showed that the size of these defects was gradually increasing. CONCLUSION: When the polyurethane membrane was exposed to bile, biodegradation was first observed at week two and increased gradually according to the duration of exposure.

Holt-Oram Syndrome is an autosomal dominant disorder characterized by the association of upper-limb abnormalities and congenital heart disease. A woman with no family history of genetic disease underwent antenatal sonography at 27 weeks' menstrual age to screen for fetal anomalies. Ultrasonography revealed abnormalities in the upper limbs. The limb abnormalities included abscence of bilateral thumbs and radius: the left humus was short. Pregnancy termination was performed. The postnatal chromosomal analysis revealed a normal 46XX karyotype and the autopsy finding confirmed the Holt-Oram syndrome. We report a case of Holt-Oram Syndrome in fetus with unaffected parents with brief of the literatures.

PURPOSE: Chronic spontaneous urticaria (CSU) in children is a common skin disorder, but its clinical course varies. We investigated the clinical course and associated factors for CSU treatment in children. METHODS: A total of 107 children, diagnosed with CSU from 2001 to 2016 in Dong-A University Hospital, who had been followed up for more than 6 months after treatment, were enrolled. The laboratory findings, and clinical aspects and courses were retrospectively investigated by a medical record review. We divided the 152 patients into 3 groups according to the treatment modalities: group 1, 1 antihistamine; group 2, more than 2 kinds of antihistamines; and group 3, antihistamines plus leukotriene receptor antagonist. RESULTS: The mean age of patients in group 3 was 3.4 years (range, 2.6–4.2 years), which was significantly lower than those at the other 2 group patients (P=0.01). The urticaria activity score (UAS) of group 3 (6.1 [5.7–6.6]) was significantly higher compared to those of the other 2 groups (P=0.01). The improvement rate of the condition in children with positive specific immunoglobulin E (sIgE) reactivity to food or inhalant allergens was significantly lower than that of children with negative sIgE reactivity (P=0.01). Sex, age, history of allergic diseases, disease duration, UAS, previous treatment, and treatment modality were not correlated with the symptom improvement rate. CONCLUSION: Younger children and those with higher UAS needed more medication to ensure the improvement in symptoms. Moreover, it took more time for the improvement in symptoms in children who were sensitized to food or inhalant allergens.

PURPOSE: We compared the reproducibility of 201Tl and 99mTc-sestamibi (MIBI) gated SPECT measurement of myocardial function using the Germano algorithm. MATERIALS AND METHODS: Gated SPECT acquisition was repeated in the same position in 30 patients who received 201Tl and in 26 who received 99mTc-MIBI. The quantification of end-diastolic volume (EDV), end-systolic volume (ESV), and ejection fraction (EF) on 201Tl and 99mTc-MIBI gated SPECT was processed independently using Cedars quantitative gated SPECT software. The reproducibility of the assessment of myocardial function on 201Tl gated SPECT was compared with that of 99mTc-MIBI gated SPECT. RESULTS: Correlation between the two measurements for volumes and EF was excellent by the repeated gated SPECT studies of 201Tl (r=0.928 to 0.986; p<0.05) and 99mTc-MIBI (r=0.979 to 0.997; p<0.05). However, Bland Altman analysis revealed the 95% limits of agreement (2 SD) for volumes and EF were tighter by repeated 99mTc-MIBI gated SPECT (EDV: 14.1 ml, ESV: 9.4 ml and EF: 5.5%) than by repeated 201Tl gated SPECT (EDV: 24.1 ml, ESV: 18.6 ml and EF: 10.3%). The root mean square (RMS) values of the coefficient of variation (CV) for volumes and EFs were smaller by repeated 99mTc-MIBI gated SPECT (EDV: 2.1 ml, ESV: 2.7 ml and EF: 2.3%) than by repeated 201Tl gated SPECT (EDV: 3.2 ml, ESV: 3.5 ml and EF: 5.2%). CONCLUSION: 99mTc-MIBI provides more reproducible volumes and EF than 201Tl on repeated acquisition gated SPECT. 99mTc-MIBI gated SPECT is the preferable method for the clinical monitoring of myocardial function.

Isolated sphenoid sinusitis is a rare disorder. There are some difficulties in its diagnosis; therefore the first presentation of this disorder might be with complications. These complications are essentially due to the anatomical location of the sinus and its proximity to the intra-cranial and orbital contents, to which infection may easily spread. A case of isolated sphenoid fungal sinusitis with unilateral abducent nerve palsy is being reported which was successfully treated by parenteral antibiotic therapy and endonasal endoscopic sphenoidotomy.

We describe a 27-year-old man who developed gait disturbance and dysarthria 2 years after the onset of cardinal symptoms of Behcet's disease. Positron emission tomography with 18F-fluorodeoxyglucose revealed severe hypometabolism in the cerebellum, in accordance wih cerebellar symptoms and sign of the patient. However, single-photon emission tomography with Tc-99m-HMPAO and Tc-99m-ECD did not disclose significant perfusion abnormalities in the brain. Routine brain magnetic resonance imaging did not show signal abnormalities. The findings of imaging studies compared with neurological manifestations of the patient are discussed.
