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.

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 experienced a case of occupational lead poisoning employed in a secondary lead smelting plant for 12 years. The patient was 39-year-old male and had been felt dizziness, recent memory impairment and intermittent severe abdominal pain for 2 years. On admission, blood lead level was 92.9 microgram/dl, urinary lead level was 19,9 microgram/l and zinc protoporphyrin level was 226.0 microgram/dl. On the blood test, hemoglobin was 10.6 g/dl and showed normocytic normochromic anemia. There were no abnormal findings in the biochemical and hormonal tests. Decrease of I.Q. and use of words in speaking were found in the psychiatric and psychologic examinations. We observed the finding of motor polyneuropathy in the nerve conduction velocity test. Computed tomographic finding showed calcification lesions in the basal ganglia, dentate nuclei, caudate nuclei, and especially characteristic multiple calcifications were located in the subcortical white matter.

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.
