Risk of Cardiovascular Disease in Patients with Behçet Disease:A Population-based Retrospective Cohort Study in Korea / 대한피부과학회지

Background@#Few studies have investigated the association between Behçet disease (BD) and cardiovascular disease (CVD). The aim of this study was to investigate the risk of various CVDs in patients with BD. @*Objective@#The aim of this study was to investigate the risk of various CVD in patients with BD. @*Methods@#Between 2003 and 2015, we performed a retrospective cohort study involving patients with BD selected from Korea’s National Health Insurance Service-National Sample Cohort database and age- and sex-matched controls. Age- and sex-matched controls were selected randomly from the NHIS-NSC database at a frequency of 1:5. @*Results@#Among the 998 patients with BD and the 4,990 controls studied, patients with BD showed significantly higher risk for angina pectoris (adjusted Hazard Ratio [HR] 1.522, 95% confidence interval [CI] 1.020∼2.273;p=0.04) and peripheral arterial disease (adjusted HR 2.939, 95% CI 1.296∼6.664; p=0.01) than the controls. The cumulative incidence rates of these diseases in patients with BD were also significantly higher than those in the controls. @*Conclusion@#Patients with BD showed independent risk for angina pectoris and peripheral arterial disease.

Primary Cutaneous Solitary Fibrous Tumor on the Back

Solitary fibrous tumors (SFT) are uncommon mesenchymal tumors. SFT have several synonyms including localized fibrous tumor, benign mesothelioma, localized fibrous mesothelioma, and submesothelial fibroma. SFT usually occur in the pleura or other serosal surfaces, but SFT can also develop in extrapleural areas including the nasal cavity, orbit, retroperitoneum, and pelvis. Cutaneous SFT is extremely rare, and more likely to occur in the head and neck region. Histologically, this tumor can mimic a variety of benign and malignant tumors such as dermatofibroma, dermatofibrosarcoma protuberans, spindle cell lipoma or other mesenchymal tumors. Most cases of SFT show non-aggressive clinical courses, with low recurrence rates. Herein, we describe a case of primary cutaneous SFT which presented with huge mass on the back.

Lymphangioma Circumscriptum of the Vulva Mimicking Condyloma Acuminatum in a Patient with Crohn’s Disease / 대한피부과학회지

While lymphangioma circumscriptum may present anywhere on the body, the vulva is a rare site. However, vulvar involvement can occur in some clinical settings, and Crohn’s disease is one of the underlying etiologies of acquired lymphangioma circumscriptum. A 31-year-old woman presented with an 8-year history of widespread verruciform plaques on her vulva. She complained of a mild itching sensation at the lesion site. She was diagnosed with Crohn’s disease 11 years prior but had not been treated. She had no history of trauma or surgery in the perineal area and no familial history of cancer or hereditary disorders. The histopathologic findings were consistent with lymphangioma. Based on the clinicopathologic findings, the patient was diagnosed with lymphangioma circumscriptum on the vulva. Herein, we report a rare case of acquired lymphangioma circumscriptum of the vulva mimicking condyloma acuminatum in a patient with Crohn’s disease.

Spontaneous Intracranial Hypotension Treated with Epidural Blood Patch

Spontaneous intracranial hypotension is a syndrome caused by cerebrospinal fluid (CSF) leakage from the spinal dural sac. The most common symptom is a postural headache and other clinical symptoms may include nausea, vomiting, photophobia, diplopia, dizziness, and tinnitus. Usually, conservative treatments like hydration, bed rest, and administration of caffeine are recommended first, but epidural blood patch is regarded as the mainstay of treatment in the patients who do not respond to conservative therapy. Epidural blood patch was known that it provides the tamponade and seal of dural sac when performed at the leak site. Our patient was suspected the CSF leakage at cervicothoracic junction, but epidural blood patch was performed in lumbar level and the headache of patient was managed successfully for at least 1 year.

Results of Surgical Treatment of Complicated Pars Planitis

We performed pars plana vitrectomy on 19 patients with pars planitis with its complications like vitreous opacity and retinal detachment.There were 16 males and 3 females with a mean age of 42.8 years.The follow-up ranged from 6 to 122 months with a mean of 25 months.Following surgery, final visual acuity was improved or unchanged in the 78.9 percent of patients.Eight cases (42.1%)showed improved vision, seven patients (36.8%) showed no change and four cases (21.1%)worse vision.Retinal detachment was successfully repaired in 17 patients and two eyes failed anatomically due to the proliferative vitreoretinopathy.The main factor favoring functional success was the short duration from the onset to the time of vitrectomy.It might be concluded that vitrectomy should be performed in the vision threatening stages on the patients with complicated pars planitis.

Production of Human Fab Monoclonal Antibody to Surface Protein, preS1, of Hepatitis B Virus using Antibody Phage Display Library / 대한면역학회지

Human monoclonal antibodies have considerable potential in the prophylaxis and treatment of viral disease. By cloning human Ig gene segments from the B cells of volunteer into pComb3 phagemid vector, antibody library was created of filamentous phage particles displaying Fab fragments on their surface after being rescued with M13KO7 helper phages. The size of library was 7x10' pfu. Phage antibodies (phabs) were panned against biotinylated preS1 using streptavidine coated Dynabead. The soluble Fab antibodies were prepared from phagemid colonies and assayed directly for the ability to bind preS1 by ELISA. And then 3DW and SGW specific to preS1 which have both heavy and light chain to form Fab fragment, were selected. The soluble Fab antibody from 3DW was expressed highly at the concentration of 0.1 - 1.0 mM of IPTG, and 5 hours postinduction. The soluble antibodies from 3DW and SGW showed their relative affinities of 2x10' M ', and Sx10 M ', respectively, and the specificities to preS1 on ELISA. Our results suggest that antibody phage display library is very useful method to generate the human monoclonal antibody and that the human Fab monoclonal antibodies specific to preS1 selected in this study open the way to treat hepatitis B as a component of passive irnmunotherapeutics.

Production of Mouse Single Chain Fv Antibody to Surface Protein of Hepatitis B virus using Antibody Phage Display Library

In this study, we are to produce the single chain variable fragment (scFv) antibodies against surface protein of hepatitis B virus (HBV) using antibody phage display technique. Balb/c mice were immunized with preS1 and cDNAs of heavy and light chains of splenic B cells from immunized mice were prepared using RT-PCR. Two cDNAs were linked with (64S) linker DNA under recombination PCR to produce single chain Fv DNA. After digestion of scFv DNA with Sp 1 and Not 1, the digested DNA was ligated into pCANTAB 5E and electroporated into E. coli XL1-Blue to prepare scFv-library. The size of library was 1 * 10' pfu/ml. Phage antibodies (phabs) against preS1 were rescued with M13K07 helper phages, and preS1-binders were selected through 3 times of panning using 96 well microtitre plates. Phage antibody clones were assayed directly for the ability to bind preS1 by ELISA. And then 7 phage antibody clones had high ELISA signals against preS1. Phabs from preS1-specific pMsc-17 had the strongest ELISA signal to preS1. Phabs from pMsc-17 were used for Western blot to preS1 and the results revealed that it was specific to preS1. To prepare the soluble scFv antibody, phabs from pMsc-17 were transfected into non-suppressor E. coli HB2151, and grown under 1 mM IPTG. Soluble scFv antibody was mainly accumulated in the periplasmic space, but small amount of antibody was secreted into culture media.
