The aim of this study was to determine if anesthesia has any influence on human memory.

Massive calcification of the left atrium (LA), known as coconut atrium or porcelain atrium, is rare. This study emphasized the importance of assessing the extent of calcification in the LA before surgery. We present a case of a 55-year-old woman with severe, long-standing rheumatic mitral stenosis complicated by massive LA calcification. Mitral valve replacement surgery and thrombus evacuation were performed. Calcified LA complicates management, particularly in determining the surgical incision site, and alters atrial wall hemostatic properties while increasing right ventricular afterload. Available diagnostic modalities allow comprehensive preoperative planning for left atrial calcification. These methods identify specific case concerns and variations to optimize outcomes.

To detect the subtype characterization and drug-resistant mutations in HIV-1 strains after the refugee movement from Syria to Turkey between 2011 and 2014 in south east border lines. Methods: A total of 65 patients were included in this study, of which 57 (88%) patients were antiretroviral therapy-naive patients. HIV-1 RNA was detected and quantified by real-time PCR assay. HIV-1 subtypes and circulating recombinant forms (CRFs) were identified by phylogenetic analysis (neighbor-joining method), and drug-resistant mutations were analyzed. Results: Three major HIV groups were indicated. Two of these groups were located in subtype B. The other group showed heterogeneity. Subtype B (48/65, 73.8%), followed by CRFs (12/65, 18.5%) was the most common strain. Subtype of CRFs consisted of CRF01_AE (9/65, 13.8%) and CRF02_AG (3/65, 4.6%). Subtype C (1/65, 1.5%), sub-subtypes A1 (2/65, 3.1%) and F1 (2/65, 3.1%) were also detected with low prevalence. The rate of overall primary antiretroviral resistance was 4.9% (3/61). Drug-resistant rate for non-nucleoside reverse transcriptase inhibitors was 4.9%. The thymidine analogue mutation rate was 13.1% (8/61). Conclusions: HIV molecular epidemiology studies are necessary to determine transmission patterns and spread. Subtype B and CRF01_AE, CRF02_AG are the most prevalent strains in the south-east of Turkey. However, subtype C, sub-subtypes A1 and F1 are of low prevalence but persist in the south-east of Turkey. In the near future, changing of HIV epidemiology will be possible in Turkey due to migration movement in border lines and resistance testing will play an important role in HIV management.

Purpose: This study was performed to compare the ability of limited- and large-volume cone-beam computed tomography (CBCT) to display isthmuses in the apical root canals of mandibular molars. Materials and Methods: Forty human mandibular first molars with isthmuses in the apical 3 mm of mesial roots were scanned by micro-computed tomography (micro-CT), and their thickness, area, and length were recorded. The samples were examined using 2 CBCT systems, using the smallest voxels and field of view available for each device. The Mann-Whitney, Friedman, and Dunn multiple comparison tests were performed (α=0.05). Results: The 3D Accuitomo 170 and i-Cat devices detected 77.5% and 75.0% of isthmuses, respectively (P>0.05). For length measurements, there were significant differences between micro-CT and both 3D Accuitomo 170 and i-Cat (P<0.05). Conclusion Both CBCT systems performed similarly and did not detect isthmuses in the apical third in some cases. CBCT still does not equal the performance of micro-CT in isthmus detection, but it is nonetheless a valuable tool in endodontic practice.
