Objectives: We aimed to evaluate the shortand mid-term results of patients with atrial septal defect (ASD) who were treated with percutaneous closure. Study design: Seventy-nine patients with a diagnosis of secundum ASD (54 female and 25 male; mean age 26.2+/-17.2; range 3 to 71] years) were included in this study. All patients were evaluated by transthoracic (TTE) and/or transesophageal echocardiography (TEE). Amplatzer septal occluder (ASO) was used for percutaneous closure in all patients. In 76 patients, the procedure was performed under local anesthesia with TTE, while in the other 3 patients, it was performed with general anesthesia under the guidance of TEE. Patients were followed up at the 1st, 3rd, 6th and 12th months and annually thereafter. Mean followup period was 13.6+/-6.6 months. Results: Mean diameter of ASDs was 18.2+/-7.5 mm and stretched diameter was 20.7+/-8.04 mm during balloon dilatation, and mean diameter of implanted devices was 22.7+/-8.5 mm. Procedural time was 40.2+/-12.6, and fluoroscopy time was 10.9+/-4.1 minutes. The procedure was successfully performed in all patients (100%). One patient with cardiac tamponade died seven days after cardiac surgery. In two patients, the implanted devices embolized to the pulmonary circulation. Residual flow was found in three patients immediately after the procedure, without residual shunts one month after closure. Mild pericardial effusion in one patient and significant residual shunt due to device malposition in another were discovered at 1 and 6 months of the postprocedural follow- up period, respectively. Conclusion: Our findings showed that percutaneous closure of ASDs is successful in most patients with a low complication rate, and demonstrated that residual shunts do not develop in the majority of patients in the shortand mid- term.
The Severity of Periodontal Disease in Patients With Rheumatoid Arthritis: a Comparative Study
(Nobel Ilac, 2015) Ozkan, Yasemin; Alpayci, Mahmut; Ozkan, Mehmet; Hiz, Ozcan; Bozan, Nazim
Objective: There is an increasing interest in the associations between oral health and auto-inflammatory diseases. Rheumatoid arthritis (RA) and periodontal disease (PD) are the most common chronic inflammatory conditions often coexist as well. The aim of this study is to evaluate and compare RA patients and healthy controls in terms of PD severity and jaw gripping force. To our knowledge, there is only one study evaluating jaw gripping force of patients with RA in the literature. Material and Method: RA patients (n=60) and healthy controls (n=60) were included in the study. Both RA patients and the control group were examined for their gingival index, plaque index, probing dept, attachment loss, and number of teeth. In addition, jaw gripping forces of all participants were measured by digital dynamometer. The data obtained were compared between two groups. Results: There were no significant differences in participants' age, gender, body mass index, education level, frequency of tooth brushing and smoking between two groups (all, p>0.05). RA patients' scores were significantly lower compared to controls considering the number of teeth (respectively, 16 and 20; p<0.001) and jaw gripping force (respectively, 0.6 and 1.30; p<0.001). Conclusion: There is a strong association between RA and PD. The severity of PD is significantly increased in RA patients compared to healthy controls. Periodontal health should be considered in the management of patients with RA.
