BACKGROUND Achenbach’s syndrome is a rare condition, and the etiology is unknown. It is most commonly seen in the volar plate of the hand distal interphalangeal joint. Patients diagnosed with Achenbach’s syndrome in cardiovascular surgery clinic were retrospectively compared with the literature. AIM To investigate the symptoms, findings, sociodemographic conditions, and laboratory data of patients diagnosed with Achenbach’s syndrome. METHODS The study is a retrospective review of 24 patients diagnosed with Achenbach’s syndrome at Afyonkarahisar State Hospital between March 2015 and November 2016, at Sivas Numune Hospital between November 2016 and November 2017, and at Cumhuriyet University Cardiovascular Surgery Department between November 2017 and November 2018. In the study, demographic characteristics of the patients, signs and symptoms of the disease, and laboratory data were analyzed retrospectively. RESULTS The cohort consisted of 83.33% female patients and 16.67% male patients. The disease was most commonly located in the index finger of the right hand. All of the patients complained of bruising and pain. No pathologic findings were present in the laboratory results. According to these results, it can be concluded that Achenbach syndrome is most commonly seen in the right index finger of middle-aged female patients. CONCLUSION Further research is needed to clarify Achenbach’s syndrome and to develop a diagnosis and treatment algorithm. As the awareness of this syndrome increases, large amounts of data will be obtained. According to current knowledge, Achenbach’s syndrome is not among the known causes of mortality or morbidity. However, it is unknown whether it is seen in brain or other vital organs.

Objectives In this study, the effects of anastomosis techniques on the results of patients with autogenous radial-cephalic proximal forearm fistula were investigated. Methods Patients who underwent radial-cephalic proximal forearm fistula surgery (arteriovenous fistula) between April 2015 and August 2017 at the Department of Cardiovascular Surgery of Ordu University were compared retrospectively in terms of the results of anastomosis techniques. The study included 131 patients who had arteriovenous fistulas created by side-to-side and end-to-side anastomosis technique. Results There was no significant difference in demographic data, comorbidities, radial artery, and cephalic vein diameters in patients undergoing radial-cephalic proximal forearm fistula surgery. However, it was observed that fistula maturation was earlier in the group with end-to-side anastomosis technique, and the one-year patency rates were higher in the group with side-to-side anastomosis technique. Conclusion In Arteriovenous fistulas created in the proximal forearm region, the one-year patency rate of the side-to-side anastomosis technique was higher, while the maturation of the end-to-side technique observed earlier.

Background. Titanium dioxide (TiO 2 ) is widely used in many fields such as food, cosmetics, and paper industries. Studies on the photocatalytic properties of TiO 2 on living tissue are limited. Objectives.To examine the histopathological effects of TiO 2 solution on the marginal veins of rabbit ears under ultraviolet (UV) light. Materials and methods.In this study, 4 groups of rabbits (8 rabbits per group) were used: the 1 st group was the control group, the 2 nd group received 20% of nano-TiO 2 only, the 3 rd group received UV light only, and the 4 th group received nano-TiO 2 and UV light, simultaneously. The study lasted for 14 days and samples were taken from the marginal ear vein on the 15 th day.Results. The ear tissues of rabbits in the control and TiO 2 groups showed a normal histological appearance. In the UV group, the results showed severe chronic inflammation due to mononuclear cells around the hair follicles and perivascular areas. However, these findings decreased in the UV/nano-TiO 2 group. Conclusions.The method applied in this study can be used in the treatment of telangiectasia in the future. However, this study investigating the effects of nano-TiO 2 on vascular structures under UV light had a predominantly histological and observational nature. Further studies involving genetic, cytogenetic, biochemical, histochemical, and immunohistochemical analyses need to be performed to test the theories we proposed.

Background/Aim: Many factors affect the results of a surgical operation, one of which is the harmony of the materials used during surgery with the tissue. Zirconia is a material with antimicrobial properties, high surface sensitivity and robustness. This study was conducted to observe the acute and subacute effects of the nano-based zirconia surgical blade on living tissue. Methods: The study was conducted after approval was granted by the Sivas Cumhuriyet University Animal Experiments Local Ethics Committee with the decision number 65202830-050.04.04-33. A total of 16 rats were used in the study. Eight were incised with classic steel surgical blade and eight, with nanobased zirconia surgical blade. A total of 4 incisions were performed to each rat and the incisions were closed with 3.0 polypropylene suture. Tissue samples were obtained from the incisions on day 0, 3, 7 and 21, and examined histologically. Results: The epidermis layer thickness on days 7 and 21 (P=0.030, P=0.025), the dermis layer thickness on days 3 and 7 (P=0.035, P=0.030), muscle layer thickness on days 7 and 21 (P=0.030, P=0.025) were significantly increased and inflammatory cells were significantly less on days 3, 7 and 21 (P=0.030, P=0.020, P=0.025) in the nano-ceramic surgical blade compared to the other group. Collagen tissue density was significantly higher in favor of the nano-ceramic blade on the 3 rd and 7 th days (P=0.025, P=0.020). Conclusion: Nano-based zirconia surgical blade has been shown to have positive effects on wound healing. The use of nano-based zirconia surgical blade should be kept in mind in patient groups with wound healing problems.
