Perspective of turkish medicine students on cancer, cancer treatments, palliative care, and oncologists (ares study): A study of the palliative care working committee of the turkish oncology group (TOG)

Cancer is one of the most common causes of death all over the World (Rahib et al. in Cancer Res 74(11):2913–2921, 2014; Silbermann et al. in Ann Oncol 23(Suppl 3):iii15–iii28, 2012). It is crucial to diagnose this disease early by effective screening methods and also it is very important to acknowledge the community on various aspects of this disease such as the treatment methods and palliative care. Not only the oncologists but every medical doctor should be educated well in dealing with cancer patients. Previous studies suggested various opinions on the level of oncology education in medical schools (Pavlidis et al. in Ann Oncol 16(5):840–841, 2005). In this study, the perspectives of medical students on cancer, its treatment, palliative care, and the oncologists were analyzed in relation to their educational status. A multicenter survey analysis was performed on a total of 4224 medical school students that accepted to enter this study in Turkey. After the questions about the demographical characteristics of the students, their perspectives on the definition, diagnosis, screening, and treatment methods of cancer and their way of understanding metastatic disease as well as palliative care were analyzed. The questionnaire includes questions with answers and a scoring system of Likert type 5 (absolutely disagree = 1, completely agree = 5). In the last part of the questionnaire, there were some words to detect what the words “cancer” and “oncologist” meant for the students. The participant students were analyzed in two study groups; “group 1” (n = 1.255) were phases I and II students that had never attended an oncology lesson, and “group 2” (n = 2.969) were phases III to VI students that had attended oncology lessons in the medical school. SPSS v17 was used for the database and statistical analyses. A value of p < 0.05 was noted as statistically significant. Group 1 defined cancer as a contagious disease (p = 0.00025), they believed that early diagnosis was never possible (p = 0.042), all people with a diagnosis of cancer would certainly die (p = 0.044), and chemotherapy was not successful in a metastatic disease (p = 0.003) as compared to group 2. The rate of the students that believed gastric cancer screening was a part of the national screening policy was significantly more in group 1 than in group 2 (p = 0.00014). Group 2 had a higher anxiety level for themselves or their family members to become a cancer patient. Most of the students in both groups defined medical oncologists as warriors (57% in group 1 and 40% in group 2; p = 0.097), and cancer was reminding them of “death” (54% in group 1 and 48% in group 2; p = 0.102). This study suggested that oncology education was useful for the students’ understanding of cancer and related issues; however, the level of oncology education should be improved in medical schools in Turkey. This would be helpful for medical doctors to cope with many aspects of cancer as a major health care problem in this country. © 2018, American Association for Cancer Education

The effects of pregabalin on kidney tissue of the rats those have ureter obstruction [Üreter Obstrüksiyonu yapılan ratlarda pregabalinin Böbrek Dokusu üzerine etkileri]

Background: Various algorithms and treatment guidelines have been established for the treatment of neuropathic pain. In summary, tricyclic antidepressants, anticonvulsants, serotonin reuptake inhibitors and opioids are used in these algorithms. Pregabalin is an anticonvulsant drug that is frequently used in the treatment of neuropathic pain. During the use of kidneys in patients with renal insufficiency due to the need to change the dose was taken attention. Therefore, in our study, we aimed to investigate the effects of pregabalin on renal tissue in rats with renal failure due to ureter obstruction. Materials and Methods: After the approval of the ethics committee, 24 rats were randomly divided into four groups: Group C: Control, Group P: Pregabalin, Group UO: Ureter Obstruction, UO-P Group: Ureter Obstruction - Pregabalin. Urinary obstruction groups underwent a low abdominal incision under ketamine anesthesia to reach the distal right ureter and suture was placed with 2.0 mersilene and was waited for 3 weeks for late stage renal failure. In group P and UO-P rats, pregabalin was administered intraperitoneally at a dose of 100 mg / kg. After the twenty-four hour followup period, rats were sacrificed with the blood taken from the intraabdominal aorta by intraperitoneal ketamine (100 mg / kg). Blood samples were stored at -20 ° C and urea, creatinine, MDA and NO were studied. In the kidney tissue, caspase 3, 8 enzymes and histopathological evaluation were performed. Results: Caspase 3 enzyme activity was significantly increased in UO groups. In addition, pregabalin administration significantly increased the activity of caspase 3 in the UO-P group compared to the P group. The enzyme activity of caspase 8 was similar between the groups. Light microscopy revealed significant changes in UO groups, especially in the kidney tissue, which was obstructed. NO and MDA enzyme activities increased significantly in UO groups. In addition, pregabalin administration significantly increased NO and MDA enzyme activities in UO-P group compared to P group. Urinary obstruction significantly increased urea and creatinine levels. Pregabalin administration also increased urea and creatinine levels in the UO-P group compared to the P group. Conclusion: Pregabalin, which is frequently used in the treatment of neuropathic pain, has not been found to increase the renal damage that occurs experimentally in renal failure rats. We believe that our findings should be supported by a wide range of experimental and clinical studies. © Copyright 2019 by Gazi University Medical Faculty

Simultaneous occurrence of different follicular neoplasms within the same thyroid gland [Aynı tiroid bezinde farklı foliküler hücre kökenli neoplazilerin birlikteliği]

Purpose: Neoplasms of the thyroid gland are classified according to the cells they originate from and commonly develop from cells of follicular origin. The most common differentiated thyroid cancers (DTC) are papillary and follicular carcinomas. Coexistence of two different histological types of primary follicular thyroid neoplasm is a rare condition. There are previous reports of concomitant medullary and papillary thyroid cancers. However, there is scarce data about the simultaneous occurrence of the two different histological types of primary follicular thyroid tumors and this is the first study on that subject. Material and Method: From January 2007 to September 2014, our institutional database was reviewed for patients who underwent thyroid surgery for various indications. Medical records and cytopathology reports of those patients were examined retrospectively. Simultaneous neoplasms of follicular origin were noted. Results: A total of 3.700 patients were operated. Histopathological examination revealed a benign pattern in 2.686 (73%) patients and a malignant pattern in 1.014 (27%) patients. Among the patients with the diagnosis of DTC, only 20 (1.9%) had a concomitant neoplasm within the same thyroid gland. Discussion: Such simultaneous tumors may be a part of a familial tumor syndrome or an unidentified novel gene mutation playing role in the pathogenesis of more than one type of tumor. Based on the current evidence, the synchronous occurrence of those neoplasms in a given patient is likely coincidental in the literature. Further studies on larger patient population with standardized genetic characterization are needed. © 2016, Galenos Yayincilik. All rights reserved

Alprostadil and iloprost were given starting simultaneously with the reperfusion period. Effects of agents on renal, lung, and skeletal muscle (gastrocnemius) tissue specimens were examined.Results: Renal medullary congestion, cytoplasmic swelling, and mean tubular dilatation scores were significantly lower in the alprostadil-treated group than those found in the I/R-only group (P&lt;0.0001, P=0.015, and P&lt;0.01, respectively). Polymorphonuclear leukocyte infiltration, pulmonary partial destruction, consolidation, alveolar edema, and hemorrhage scores were significantly lower in alprostadil- and iloprost-treated groups (P=0.017 and P=0.001; P&lt;0.01 and P&lt;0.0001). Polymorphonuclear leukocyte infiltration scores in skeletal muscle tissue were significantly lower in the iloprost-treated group than the scores found in the nontreated I/R group (P&lt;0.0001).Conclusion: Alprostadil and iloprost significantly reduce lung tissue I/R injury. Alprostadil has more prominent protective effects against renal I/R injury, while iloprost is superior in terms of protecting the skeletal muscle tissue against I/R injury.
