Öğe Early and late advanced atrioventricular black in acute inferior myocardial infarction(Lippincott Williams & Wilkins, 1998) Altun, A; Özkan, B; Gürçagan, A; Kadi, H; Özçelik, F; Özbay, GBackground Advanced atrioventricular block is a frequent complication in patients with inferior acute myocardial infarction (AMI); in patients in hospital, it often occurs concurrently with other complications and is associated with high mortality, Very little information is available about early and late advanced atrioventricular block in inferior AMI, We hypothesized that the time of appearance of advanced atrioventricular block characterized by poor response to atropine requiring temporary pacemaker therapy may affect the prognosis of patients with inferior AMI. Methods We studied 51 patients with inferior AMI and advanced atrioventricular block characterized by poor response to atropine requiring temporary pacemaker therapy. According to pre-established electrocardiographic criteria and the time of appearance of the advanced atrioventricular block, patients were divided into two groups: an early block group consisting of 30 patients who developed advanced atrioventricular block during the first 24 h of inferior AMI, and a late block group consisting of 21 patients who developed advanced atrioventricular block after the first 24 h of chest pain. Results The groups were similar regarding age, coronary risk factors, frequency of right ventricular infarction, QRS score, atrial and ventricular rates, the time of return to first-degree atrioventricular block, cardiac arrhythmias, heart failure and mortality. The early advanced atrioventricular block group included a greater number of men than did the late group (P = 0.017). Conclusion These data suggest that the time of appearance of advanced atrioventricular block does not affect the prognosis of hospital patients with inferior AMI.

Authors of several studies reported that patients with inferior AMI complicated by atrioventricular block, concomitant precordial ST-segment depression and involvement of right ventricle have larger infarctions and a worse prognoses than do patients without these features. Objective To analyse the incidence, clinical course and in-hospital prognosis of patients with heart failure and first inferior AMI. Methods We analysed in 257 consecutive patients with first inferior AMI who had been admitted to the coronary care unit during January 1991 and March 1995. The clinical and electrocardiographic characteristics, as well as the morbidities and in-hospital mortalities, of groups of patients with and without heart failure during inferior AMI were compared. Results Symptoms and signs of heart failure were noted for 49 patients (19%). We found that patients who had suffered heart failure during inferior AMI were older (61.1 +/- 9.86 versus 58.78 +/- 1 0.58 years, P<0.05) than those who had not suffered heart failure. There was no significant difference between patients' sex, history of diabetes mellitus, hypertension, smoking status, thrombolytic therapy, involvement of right ventricle and QRS score for these two groups. We found a greater prevalence of ST-segment depression (ST-segment depression greater than or equal to 1 mV in more than one precordial lead with maximal ST-segment depression in leads V4-V6) of V4-V6 precordial leads (57 versus 26%, P=0.00002) and a lesser prevalence of no ST-segment depression (ST-segment depression <0.1 mV in each precordial lead; 14 versus 38%, P=0.001) among patients who had suffered heart failure. We found greater incidences of serious ventricular arrhythmias (53 versus 26, P=0.0002) and ventricular tachycardia-fibrillation (16 versus 7%, P=0.03) among patients who had suffered heart failure than we did among those who had not. Third-degree atrioventricular block was more often found in patients who had suffered heart failure (23 versus 12%, P=0.07) but this difference was not statistically significant. We found that the in-hospital mortality among patients who had suffered heart failure was much higher than that among those who had not (24.5 versus 3.8%, P=0.000001). Conclusion We found that heart failure occurs primarily in old patients, and in those with precordial ST-segment depression, especially in leads V4-V6. The patients who suffer heart failure have worse in-hospital prognosis due to serious ventricular arrhythmias and cardiogenic shock. Coronary Artery Dis 10:455-458 (C) 1999 Lippincott Williams & Wilkins.Öğe Invasive coypus, Myocastor coypus (Molina, 1782), in the European part of Turkey(Science From Israel-Division Of Laser Pages Publ Ltd, 1999) Özkan, B[Abstract Not Available]Öğe On the Turkish populations of Dryomys nitedula (PALLAS, 1779) and Dryomys laniger felten and storch, 1968 (Mammalia: Rodentia)(Hungarian Natural History Museum, 2003) Yigit, N; Çolak, E; Çolak, R; Özkan, B; Özkurt, SDryomys nitedula occurring in Turkish Thrace and Anatolia, and Dryomys laniger were morphologically and biometrically compared to each other. In addition, the blood serum proteins of D. nitedula and D. laniger were examined by the SDS - PAGE technique. There are very small morphological differences among the populations of D. nitedula, but the shapes of the braincase, tympanic bullae and mandible morphologically distinguished D. nitedula from D. laniger. In pair-wise biometric comparisons, nine biometric characteristics were found to differ statistically between D. nitedula (Thrace) and D. nitedula (Anatolia), 16 characteristics between D. nitedula (Turkish Thrace) and D. laniger, I I characteristics between D. nitedula (Anatolia) and D. laniger (p < 0.05). UPGMA cluster analysis established links between D. nitedula (Turkish Thrace) and D. nitedula (Anatolia) with a distance of 0.042, and D. laniger was connected to this cluster with a distance of 0.084. In the patterns of blood serum proteins, eight or nine bands were identified in the globulin zone, one band in the post-albumin and albumin zones and one or two bands in the pre-albumin zone of both species.Öğe Wood mice, Apodemus of two Turkish islands(Inst Vertebrate Biology As Cr, 1999) Özkan, B; Krystufek, BTaxonomic identity of 209 wood mice (Apodemus) from Turkish islands of Gokceada and Bozcaada was evaluated on the basis of cranial characteristics, and using comparative mainland material from European and Asiatic Turkey. Specimens from Gokceada belonged to A. flavicollis, but differed from the mainland sample in having longer incisive foremen and shorter palatinum. Bozcaada was populated by A. hermonenis, which is the first record of this species on any island. Wood mice were the most common small mammals on both islands; their dominance on Gokceada was 39.6% and on Bozcaada 92.3%. We discuss zoogeographic relations of the Aegean islands on the basis of four Apodemus species recorded there so far.
