    The Level of Knowledge and Awareness of Male University Personnels about Adult Cancers and Cancer Screening
    (Duzce Univ, Fac Medicine, 2021) Sevinc, Nergiz; Korkut, Burcu; Nacar, Erkay; Ozturk, Erdal
    Objective: Cancer incidence rates have been increasing for both genders. The first aim was to determine the knowledge level of men about the types of cancers on adults. The second aim was to assess the level of knowledge of them on cancer screening programs. Methods: This cross-sectional study was conducted at Karabuk University in 2020, with 312 males who worked as academicians, administrative personnel and contractlabor. A questionnaire on sociodemographic characteristics and the knowledge of male employees about cancer and cancer screenings was applied to the participants by interviewing in the university. Results: The mean age of male participants was 40 years. Of the participants, 39.7% knew that lung cancer is the most common type of cancer among men while 80.4% knew that breast cancer is the most common type of cancer among women. Of the participants, 42.9% heard of the Center of Early Detection and Screening of Cancer (CEDSC) and only 12.5% had a cancer screening test. The participants' answers to the question Which cancer screening tests are made in CEDSC? were breast cancer (55.8%), cervical cancer (35.6%), colorectal cancer (31.1%) and prostate cancer (26.0%). Mammography was the most well-known among screening tests (51.9%). The level of knowledge on colon, cervical and prostate cancer screening tests increased with age (p<0.05). Conclusions: The level of knowledge about cancer and cancer screenings of male participants was mostly moderate. It might be possible to increase the level of knowledge on cancer and cancer screening of men by preparing educative and informative programs.

    PARANASAL SINUS ANATOMICAL DIFFERENCES IN ELDERLY PATIENTS
    (Gunes Kitabevi Ltd Sti, 2020) Yilmaz, Nihat; Mulazimoglu, Selcuk; Oner, Serkan; Nacar, Erkay; Yilmaz, Orhan
    Introduction: Endonasal endoscopic sinus surgeries performed on elderly patients can be challenging due to anatomical variations, and can be studied using preoperative computed tomography. The aim of the present study was to evaluate paranasal sinus anatomical differences in elderly patients compared to a younger control group. Materials and Methods: We retrospectively evaluated paranasal computed tomography scans of 47 elderly patients (>65 years old) (Elderly group) and 47 younger patients (Control group) for midfacial skeletal size (interzygomatic buttress distance, nasion-basion distance), anatomical variations, dimensions, and paranasal sinus volumes. Results: The mean age of the Elderly group was 69.89 years (65- 81 years) and the mean age of the Control group was 33.15 years (20-49 years). There was no significant difference in midfacial size between the two groups. The prevalence of Keros Type Ill olfactory fossa was significantly higher in the Elderly group than in the Control group (p<0.05). The Elderly group had a significantly lower mean maxillary sinus volume (p<0.01) and mean anteroposterior diameter of the sphenoid sinus (p<0.01) compared to the Control group. Furthermore, there was no significant difference in the maxillary sinus volume between the elderly edentulous and dentulous patients(p>0.05). Conclusion: Elderly patients have more Keros Type Ill olfactory fossa, which confers a higher risk of iatrogenic cerebrospinal fluid leakage during endoscopic sinus surgery. The preoperative detailed evaluation of computed tomography scans of elderly patients should include, but not be limited to, the ethmoid roof for deep olfactory fossa, and the sphenoid sinus for its narrow anterioposterior dimention.

    Prevalence of metacarpophalangeal sesamoid bones of the hand in Turkish population
    (Turkish Joint Diseases Foundation, 2021) Ergen, Emre; Yilmaz, Ozgur; Ari, Bunyamin; Nacar, Erkay; Cimen, Ayla Ozaydogdu; Ertem, Kadir; Aslanturk, Okan
    Objectives: This study aims to investigate the prevalence and location of the metacarpophalangeal (MCP) sesamoid bones using computed tomography (CT) images. Patients and methods: A total of 767 hands of 735 patients (503 males, 232 females; mean age: 36.9 +/- 17.0 years; range, 18 to 105 years) obtained from picture archiving and communication system were retrospectively analyzed between January 2016 and December 2019. The sesamoid bones of MCP joints I, II, III, IV, and V were recorded. Data including age, sex, side, number, pathologies, and location of the sesamoid bones were recorded. Results: The prevalence of sesamoid bones was found to be 100%, 37.61%, 1.17%, 0.5%, and 80% in MCP I, II, III, IV, and V, respectively. There was no significant correlation between the sex of the patient and presence of sesamoid bone at MCP II or MCP V (p>0.970 and p=0.176, respectively). The presence of sesamoid bone at MCP II was statistically significantly correlated with the presence of sesamoid bone at MCP V (p<0.001). There was no statistically significant difference in the side and sesamoid prevalence in the remaining 703 patients (p>0.05). Conclusion: The prevalence of MCP V sesamoid bone is higher than previous studies from our country. The CT of hand can be used to determine sesamoid fractures and degenerative conditions of sesamoids.
