    (Via Medica, 2024) Oner, Zulal; Oner, Serkan; Sahin, Necati Emre; Cay, Mahmut
    Background: This study aimed to evaluate the congenital anomalies of ribs in the Turkish population using multi-detector computed tomography (CT) and to reveal the prevalence and distribution of these anomalies according to sexes and body sides. Materials and methods: This study included 1120 individuals (592 male, 528 female) over 18 who presented to our hospital with a suspicion of COVID-19 and who had thoracic CT. Anomalies such as a bifid rib, cervical rib, fused rib, Srb anomaly, foramen rib, hypoplastic rib, absent rib, supernumerary rib, pectus carinatum, and pectus excavatum, which were previously defined in the literature, were examined. Descriptive statistics were performed with the distribution of anomalies. Comparisons were made between the sexes and body sides. Results: A prevalence of 18.57% rib variation was observed. Females had 1.3 times more variation than males. Although there was a significant difference in the distribution of anomalies by sex (p = 0.000), there was no difference in terms of body side of anomaly (p > 0.05). The most common anomaly was the hypoplastic rib, followed by the absence of a rib. While the incidence of the hypoplastic rib was similar in females and males, 79.07% of the absent ribs was seen in females (p < 0.05). The study also includes a rare case of bilateral first rib foramen. At the same time, this study includes a rare case of rib spurs extending from the left 11(th) rib to the 11(th) intercostal space. Conclusions: This study demonstrates detailed information about congenital rib anomalies in the Turkish population, which may vary between people. Knowing these anomalies is essential for anatomy, radiology, anthropology, and forensic sciences.

    (Soc Chilena Anatomia, 2024) Sahin, Necati Emre; Bakici, Rukiye Sumeyye; Toy, Seyma; Oner, Zulal
    This study aims to examine the hand morphometry of healthy young individuals from different countries and investigate the differences between countries in typing of hand based on the morphometric values obtained. In the study, 16 different parameters, including two surface areas and 14 lengths, were measured from the right hand of 579 volunteers (250 females, 329 males) from 7 different countries (Turkey, Chad, Morocco, Gabon, Kazakhstan, Senegal and Syria). Factor analysis was performed on the parameters, cluster analysis was performed according to the factor score obtained, and the hand types in the study were determined. As a result of the study, four different hand types were defined, and the distribution of these types according to countries was analyzed. All parameters showed significant differences between countries in both genders (p<0.05). According to the results of the study, there was a difference between male and female hand types between countries. In females, the type 1 hand type was found only in Gabon, the type 2 hand type was found only in Senegal, the type 3 hand type was found in Turkey, Morocco and Kazakhstan, while the type 4 hand type was significantly distributed in Senegal and Gabon (X-2 =104.62; df=18, p<0.05). In males, type 1 hand type was found in Turkey, type 2 hand type in Senegal and Gabon, type 3 hand type in Turkey, while type 4 hand type was significantly distributed in Morocco and Kazakhstan (X-2 =76.964; df=18, p<0.05).

    Evaluation of palmar creases of healthy young individuals of different countries
    (Cukurova Univ, Fac Medicine, 2024) Sahin, Necati Emre; Bakici, Rukiye Sumeyye; Oner, Zulal; Toy, Seyma
    Purpose: This study aims to evaluate the potential effects of gender and country factors on palmar creases by examining the palmar creases of young adults from various countries. Materials and Methods: The study involved a total of 220 volunteers, including 120 males and 100 females aged 18-30, from seven different countries (Jordan, Sudan, Somalia, Iran, Iraq, Tanzania and Turkey), as well as students from Karabuk University. Hand types were evaluated based on palmar creases and the number of origins for both hands. Total Degree of Transversality (TDoT) values for palmar creases were calculated. Classification of palmar creases and comparison of T -DoT values for both hands were performed between genders and countries. Results: The study analyzed 440 hands from 220 individuals, identifying 1 Simian, 8 Suwon, and 5 Sydneytype hands, while categorizing the remaining 426 hands as normal type. Regarding the number of palmar crease origins, it was observed that there was a single origin in 3 hands, two origins in 309 hands and three origins in 119 hands. Significant associations were found between genders and countries in the number of palmar crease origins. In addition, significant differences in right hand TDoT values were found between genders and countries. Conclusion: In spite of limitations in sample selection and size, these results are important in providing a basis for future in-depth research on palmar creases at later stages, although generalizability to the specific countries represented in the sample may be limited. Consequently, this study highlights variations among countries concerning both the number of palm crease origins and right-hand T -DoT values.

    Examination of the Correlation of Distal End Parameters of the Humerus with Other Parameters
    (Galenos Publ House, 2022) Toy, Seyma; Bakici, Rukiye Suemeyye; Sahin, Necati Emre
    Objective: The aim of this study is to determine the correlation between all osteometric parameters obtained from the humerus and parameters obtained from the distal end of the humerus.Materials and Methods: A total of 16 parameters were measured in 67 dry bones using the Image-J program.Results: Groove for the ulnar nerve width (GUW) and the angle of the groove of the ulnar nerve (GUA) parameters were found to be higher on the left side and the difference was found to be statistically significant (p<0.05), GUA and intertubercular groove width were not significantly correlated with any parameter (p>0.05).Conclusion: We believe that the results of the study will provide osteometric data of the humerus in distal end fracture treatment, comminuted fractures, and reconstructive surgery of the humerus, anthropological and forensic studies and increase the anatomical knowledge levels of experts interested in the region.

    Investigation of total cerebellar and flocculonodular lobe volume in Parkinson's disease and healthy individuals: a brain segmentation study
    (Springer-Verlag Italia Srl, 2024) Ozgen, Merve Nur; Sahin, Necati Emre; Ertan, Nurcan; Sahin, Bunyamin
    Background Parkinson's disease (PD) is a neurodegenerative disorder with an unexplored link to the cerebellum. In the pathophysiology of balance disorders in PD, the role of the flocculonodular lobe (FL) is linked to the impairment of the dopaminergic system. Dopamine deficiency can also lead to changes in cerebellum functions, disrupting balance control. This study compares cerebellar and FL volumes between healthy controls (HC) and PD patients, analyzing their correlation with clinical outcomes. Methods We used magnetic resonance images of 23 PD patients (14 male, 9 female) and 24 HC (9 male, 15 female). Intracranial (ICV), total cerebellar, FL, and cerebellar gray matter volumes were measured using VolBrain. Clinical outcomes in PD patients were assessed using the Unified Parkinson's Disease Rating Scale (UPDRS-III) to evaluate motor function, with scores correlated to volumetric data. Results The cerebellar and gray matter volumes in HC were 115.53 +/- 10.44 cm(3) and 84.83 +/- 7.76 cm(3), respectively, compared to 126.83 +/- 13.47 cm(3) and 92.37 +/- 9.45 cm(3) in PD patients, indicating significantly larger volumes in PD patients (p < 0.05). The flocculonodular lobe gray matter volume was 1.14 +/- 0.19 cm(3) in PD patients and 1.02 +/- 0.13 cm(3) in HC, but there was a significant increase in gray matter volume in PD patients between the groups (p < 0.05). In PD patients, significant negative correlations were observed between FL volume and the UPDRS-III scores (r = - 0.467, p = 0.033) and between UPDRS-III scores and both total (r = - 0.453, p = 0.039) and normalized (r = - 0.468, p = 0.032) gray matter volumes of the FL. Conclusion Although total gray matter volumes were larger in PD patients, the volumes of FL did not differ between groups. In Parkinson's disease, increased cerebellar volume may regulate fine motor movements rather than balance.

    A study on the correlation between spleen volume estimated via cavalieri principle on computed tomography images with basic hemogram and biochemical blood parameters
    (Medrang, 2022) Sahin, Necati Emre; Oner, Zulal; Oner, Serkan; Turan, Muhammed Kamil
    Considering its hematological and immunological functions, spleen is a very important organ. A change occurs in its size as the spleen performs these functions. This study aims to examine the possible relationships between spleen volume and the basic hemogram and biochemical parameters in serum. Multidetector computed tomography images and basic hemogram and biochemical parameters of 74 adult individuals, 34 male and 40 female, who were found to be healthy, were used in the study. Spleen volume was estimated using the Cavalieri method on multidetector computed tomography images and the correlations between the volume value with basic hemogram and biochemistry parameters were researched. While negative significant correlations were found between the estimated spleen volume and lymphocyte percentage (r=-0.224) and platelet level (r=-0.271); positive significant correlations were found between hemoglobin level (r=0.228), hematocrit level (r=0.237), alanine aminotransferase (r=0.345), and erythrocyte level (r=0.375). As a result of this study, a relationship was found between spleen volume and lymphocyte percentage, hematocrit level, erythrocyte level, platelet level, and alanine aminotransferase level in serum. We believe that the results of the study will provide a larger perspective to clinicians in the diagnosis of diseases associated with spleen.
