- MakaleAçık Erişim2024Characteristics of Patients Diagnosed as Brain Death in Intensive Care Unit of a Tertiary Hospital
Karaca, Nurcan Kutluer; Karakurt, Tülay Ceren Ölmeztürk
Objective: The aim was to examine the characteristics of brain death cases detected in the intensive care unit of our hospital in the last 12 years, respectively. Methods: In this study, archive records of cases diagnosed with brain death in an intensive care unit between January 1, 2011, and December 1, 2022, were examined. Demographic characteristics, hospitalization diagnoses, time until apnea test and cardiac arrest, supporting tests used in diagnosis, acceptance rates of organ donation by families, transplanted organs, and blood groups of patients were recorded. Results: Thirty-five cases diagnosed with brain death were included in the study. The most common diagnosis among these patients was intracranial hemorrhage (68%) at initial admission. The apnea test was completed in 94.7% of the patients, and radiological imaging methods were used to support the diagnosis of brain death in 62.9% of the patients. Anesthesiology and reanimation specialists had taken part in all diagnoses. The mean timespan from hospitalization to the apnea test was 5.94 ± 3.07 days. The timespan for the diagnosis of brain death was 6.17 ± 3.02 days. A total of 22.8% of the cases were organ donors. The liver was the most often donated organ (49%). Conclusion: Revealing the characteristics of patients diagnosed with brain death will inform us about which patient groups can be donor candidates. Thus, the number of donor organs from cadavers will be increased.
- MakaleAçık Erişim2024Association Between Acromiohumeral Interval and Isolated Supraspinatus Muscle Tears Using Magnetic Resonance Imaging
Kızılgöz, Volkan; Çetin, Türkhun; Kahraman, Şevket
Objective: The authors aimed to investigate the acromiohumeral interval (AHI) using Ellman’s classification in patients with isolated supraspinatus tendon tears. The AHI differences between patients and controls, in addition to controls, partial tears, or total supraspinatus ruptures, were compared concerning AHI differences. Methods: The imaging was performed using a 1.5 Tesla (T) magnetic resonance imaging (MRI) device and a shoulder coil. The AHI measurements were determined by taking the average of measurements in 3 different planes. For Ellman’s classification, the grading of the tear was graded based on how much the depth of the tear or the thickness of the tendon was affected. Results: A total of 304 shoulder MRIs meeting the criteria were included in our study. The study included 41.4% (126/304) without rotator cuff pathology, 30.9% (94/304) with grade 1 tear in the isolated supraspinatus tendon, 6.6% (20/304) individuals with grade 2 tear, 11.8% (36/304) with isolated supraspinatus tendon grade 3 tear, and 9.2% (28/304) with grade 4 tear in the isolated supraspinatus tendon. The AHI values in men were found to be statistically significantly higher than in women. The patient group and the control group showed a significant difference regarding the AHI values. The AHI measurements were significantly lower for the patients with total rupture. Conclusion: The AHI values in isolated supraspinatus tendon injuries, including all tear groups, were found to be significantly lower than those in the patients without rupture; however, there was also a significant difference between total and partial-tear groups.
- MakaleAçık Erişim2024Changes Caused by Smoking in Hemogram Parameters in Patients Presenting to the Emergency Department
Salcan, Sara; Işık, Bahar
Objective: The aim of this 3-stage study is to reveal the smoking rate after the exclusion criteria was applied in patients who presented to the emergency department and to assess if smoking has any effect on their hemogram test results. And at last, the opinions of those included in the study are sought regarding whether establishing a smoking cessation center in the emergency department would be beneficial or not. Methods: After exclusion criteria were applied, a total of 2000 patients presenting to the emergency department were included in the study. The study was carried out in 3 stages. In the first stage, the smoking rate of 2000 patients was investigated. In the second stage, in addition to the exclusion criteria at the beginning of the study, in order to reduce the possible impact on blood parameters, those with any comorbidities (n = 747) were excluded, and hemogram parameters were compared in the remaining patients (n = 1263). Then hemogram levels were compared both in male and female in smokers and non-smokers since the normality limit of some of these values differs for both genders. In the third stage, establishing a smoking cessation center in the emergency department would be beneficial or not was statistically researched. Results: In total, 50% of the patients were male and 50% were female. The mean age was 51.57 ± 20.29 years. Of the patients, 28.26% (n = 566) were smokers. In total, 38.7% (n = 385) of men and 17.1% (n = 178) of women were smokers. The smoking rate was 30.7% in those without comorbidities, which was higher. The rate we obtained, although not directly comparable to the results of other studies due to differences in inclusion and exclusion criteria, was similar to the rate in the general population. There were significant differences in white blood cell (WBC), erythrocyte (RBC), and hemoglobin counts, as well as mean corpuscular volume (MCV) between the 2 groups. No significant difference was found in platelet count. White blood cell count was 12% higher, erythrocyte count was 3.13% higher, MCV was 1.5% higher, and eosinophil count was 24.1% higher in smokers. Hemoglobin level was 7.8% higher in smokers. When men and women without comorbidities were analyzed separately as smokers and non-smokers, hemoglobin, WBC, and eosinophil counts were higher in male smokers; hemoglobin, WBC, MCV, and eosinophil counts were higher in female smokers. Mean corpuscular volume and RBC count in men, and RBC count in women were higher in the smoker group, although it was not statistically significant. Only 33.7% of patients stated that it would be beneficial to establish a smoking cessation unit in the emergency department. Conclusion: Cigarette smoking has severe adverse effects on hematological parameters that might be associated with a greater risk of developing chronic diseases. The rate of smoking among the patients in the emergency department is similar to the general population. Making the necessary arrangements for emergency departments to become primary centers for smoking cessation and including this topic as part of residency training could be beneficial.

Objective: As a result of long-term damage to the nerves caused by harmful molecules in chronic renal failure patients who are treated with hemodialysis, the clinical manifestation defined as uremic neuropathy may occur in patients. In our study, we aimed to determine the prevalence of neuropathic pain in hemodialysis patients and to evaluate risk factors. Methods: Patients over the age of 18 who underwent hemodialysis treatment were included in our study. Demographic characteristics of the patients, duration of dialysis, and comorbidities were recorded. The Brief Pain Inventory was used to assess the patients’ pain intensity. The Neuropathic Pain Questionnaire and Neuropathic Pain Questionnaire; Short Form was employed for the evaluation of neuropathic pain. Results: Neuropathic pain was detected in 25 (41.7%) of 60 hemodialysis patients. Chronic pain was evaluated with a Likert scale as 0: no pain 10: the worst pain I can imagine. The averages for the past week were categorized as pain worst, pain least, pain average, and pain now, and recorded as 5.9, 6.5, 6.4, and 6.4, respectively. The number of comorbid disorders and the scores of neuropathic pain questionnaire in short form were determined to be statistically associated (P = .040). Conclusion: Neuropathic pain in hemodialysis patients was detected in 41.7% of the patients; it is a common symptom and is associated with the number of comorbid diseases. This study is an exemplary study in terms of evaluating the prevalence of neuropathic pain in hemodialysis patients. It has been a guide to start supportive treatments at an earlier period.
- MakaleAçık Erişim2024Sinus Maxillaris Morphometric Measurements and Comparative Anatomy Between Genders
Sunar, Mukadder; Kolak, Merve; Ocak, Ali
Objective: This study aimed to investigate the usability of the maxillary sinus as a criterion in gender determination by comparing the dimensions of the maxillary sinuses in adult males and females using cone-beam computed tomography (CBCT). Methods: Our study was designed to measure individuals’ bilateral maxillary sinus height, width, and depth with CBCT. A total of 100 patients, 50 women and 50 men between the ages of 18 and 70, were included in the study. The height (H), width (W), and depth (D) of the sinus were measured in the coronal and axial planes, and their statistical significance was evaluated. Results: In our results, the confidence interval was determined as 95% and P < .05, was considered significant. Right height (P < .001), right width (P = .045), and left height (P = .015) parameters were statistically higher in males than in females. In the discriminant analysis, the parameter that gave the best discrimination was the right height with 63%. Conclusion: In our study, it was observed that the sinus maxillaris dimensions were larger in male individuals than in female individuals, but it was concluded that it is not a definitive criterion on its own and can be used as a supporting one.
- MakaleAçık Erişim2024Appearance of Dehiscence at the Uterine Scar Site on Ultrasound: A Case Report
Yılmaz, Betül Kalkan
With the increase in cesarean section rates, uterine rupture, one of the obstetric emergencies, has become an important clinical condition leading to maternal–fetal mortality and morbidity. According to risk factors for uterine rupture, it can be classified as rupture of a previous scar (cesarean section, myomectomy), traumatic rupture of the uterus (resulting from trauma), spontaneous rupture of the uterus due to underlying pathologies (uterine anomalies, multiparity), and spontaneous uterine rupture in apparently normal primigravida patients. Among these, uterine rupture due to a scarred uterus is the most commonly seen. Currently, optimal cutoff values for predicting uterine scar rupture have not been definitively established. A 35-year-old pregnant woman, gravida 3, parity 2, with a history of 2 previous cesarean sections, was seen during a routine outpatient clinic visit when she was 23 weeks and 2 days pregnant based on her last menstrual period. During the visit, approximately a 5 cm area of amniotic fluid protruding toward the bladder was observed along the old incision line, suggesting a disruption in the continuity of the myometrium at the scar site. Preoperative preparations were made, and the patient was taken for a cesarean section. Interestingly, there was no apparent evidence of dehiscence, which is commonly seen in many patients who have had previous cesarean sections. The cesarean section was successfully completed without complications.

Kuzucu, Mehmet; Karaoğlan, Mert; Kılınç, Seda
Tilapia piscidin 4 (TP4), a cationic antimicrobial peptide, is recognized for its diverse biological roles, including antibacterial, wound-healing, and anticancer properties. Herein, the codon-optimized sequence of TP4 peptide was expressed using the pPICZαA expression vector containing the AOX1 promoter, a strong and inducible promoter, in the Pichia pastoris KM71H expression system. Recombinant TP4 peptide was purified by Ni-NTA affinity chromatography. After purification, the anticancer activity of TP4 was assessed in HUH-7 hepatocellular carcinoma cells, and the underlying mechanisms were determined. In the present study, it was demonstrated for the first time that recombinant TP4 displayed strong anticancer activity in the human HUH-7 cell line. The TP4 antimicrobial peptide can be used as a competitive candidate for the treatment of cancer cells due to its anticancer effects.

Fatihoglu, Erdem; Çetin, Türkhun; Kazci, Omer; Senbil, Duzgun Can
Objective: The aim of this study was to examine the normal values of the optic nerve in different segments of the nerve trace in the pediatric population using magnetic resonance imaging (MRI). Methods: Two radiologists retrospectively reviewed images obtained with a 1.5 tesla MR device of 426 youngsters (213 males/213 girls). Measurements were performed on the T2 sequence. Parts of the orbital region, prechiasmatic region, and optic tract were measured. Participants were divided into 5 different age groups. Results: The mean age of the population is 8.3 ± 1.5 years. The average diameter of the orbital segment of the entire population was 3.58 ± 0.53 mm, 4.74 ± 0.48 mm for the prechiasmatic segment, and 3.61 ± 0.48 mm for the optic tract section. Age correlates positively with the orbital plane (OP), prechiasmatic portion (PP), and optic tract (OT) values. All age groups have considerably varying mean OP, PP, and OP diameters. Good interobserver reliability was observed for all 3 diameter measurements (OP cap value = 0.62, PP cap value = 0.58, OT cap value = 0.67). Conclusion: Normal diameters of the optic nerve can be measured by MRI at above mentioned sections with a good interobserver reliability. These normal values can be used to detect obscure thickness changes/abnormalities in optic nerves of the children.

Objective: Hemoglobin A1c (HbA1c) is a glycosylated protein and shows the glycemic status for the last 2-3 months, and it is the most commonly used marker in routine practice. In this study we aimed to investigate the relationship between hemoglobin and HbA1c levels. Methods: In total, 4278 patients with type 2 diabetes mellitus included in this study. The study was cross-sectional, and the data of the patients were recorded by scanning the hospital automation system. Hemoglobin A1c levels of patients with and without anemia who had the same fasting blood glucose levels were compared. Results: At similar fasting blood glucose levels, HbA1c levels were found to be lower in patients with anemia than those without anemia Conclusion: Anemia status of the patients should be considered when evaluating HbA1c.
- MakaleAçık Erişim2024Evaluation of the Prognostic Value of Preoperative Electromyography in Patients Who Underwent Carpal Tunnel Release Surgery
Özcan, Seçkin; Kockara, Nizamettin; Yurten, Hakan
Objective: Carpal tunnel syndrome is a condition caused by the compression of the median nerve within the carpal tunnel, resulting in clinical symptoms in the area innervated by the nerve. The role of electromyography in surgical planning for carpal tunnel syndrome is controversial. The current study aimed to compare the clinical results of patients who underwent carpal tunnel release surgery based on their preoperative electromyography grading. Methods: We examined 102 patients who underwent carpal tunnel release surgery between 2015 and 2018. All patients were evaluated by electromyography preoperatively and 2-year postoperatively and completed the Boston Questionnaire. Based on the Bland classification for electromyography grades, the patients were divided into 2 groups: group 1 (grades 1-3) and group 2 (grades 4-6). Changes in scores were analyzed after carpal tunnel release surgery for each group. Results: When considering the results for all patients irrespective of group, both scores showed significant improvement after surgery. Group 2 exhibited greater improvement in the functional status scale score and electromyography grade compared to group 1, while similar changes were observed in the symptom severity scale scores. Conclusion: Both the symptom severity scale and functional status scale scores improved significantly after surgery for all patients. However, group 1 consistently had lower scores than group 2 across all evaluation periods. The evaluation of the improvement in the electromyography grade (ΔEMG) indicated that group 2 had better improvement than group 1. Level of Evidence: III

Objective: This study was designed to evaluate the coronavirus disease 2019 (COVID-19) status of emergency ambulance service workers, who were in front-line contact with patients during the COVID-19 epidemic, before and after the vaccination program was initiated (March 2020-July 2021). Methods: The variables gender, age, location of employment, role, COVID-19 diagnosis, immunization status, and contact with patients were evaluated among 223 Erzincan emergency ambulance service workers. Results: No significant differences in age, gender, and role in COVID-19-positive patient transfers (whether active or passive) were found between COVID-19-positive and negative healthcare workers. Moreover, there was a measurable decrease in COVID-19 cases after vaccination. Conclusion: In this study, which is one of the few investigations involving emergency ambulance service workers, 93.8% of the workers participated in the vaccination program and received 2 doses of the vaccine, and there was a measurable decrease in COVID-19 cases after vaccination. Multi-center studies may offer more statistically valuable results for this occupational group, which remained constantly active while the stay-at-home order was in place.

Objective: The purpose of this in vitro study is to evaluate the effect of various surface treatments (STs) and restorative materials on the shear bond strength (SBS) of glass hybrid (GH) restorative materials. Methods: Sixty-three GH restorative material samples (Equia Forte Fil, GC) were prepared (6 × 2 mm) and randomly divided into 3 groups according to the subsequent ST (n = 21): phosphoric acid etching (PA), aluminum oxide sandblasting (AO), and diamond bur roughening (DB). After that, 3 subgroups were created from the samples in each group based on the restoration material applied: Ionofil Molar AC (IM; Voco), Fuji II LC (FLC; GC), and Charisma Smart (CS; Kulzer). The bonded specimens were subjected to the SBS test. In addition, the samples were evaluated with a scanning electron microscopy. The results were statistically examined using twoway analysis of variance with post hoc test (P = .05). Results: The CS groups were higher in SBS compared to the other groups, whereas the IM groups had low bond strength (P < .05). The FLC, CS, DB, and PA groups showed the highest SBS (P < .05). The lowest SBS values were observed in the PA group in IM (P < .05). Conclusion: The GH restorative materials were successfully repaired with composite resin using diamond bur roughening or phosphoric acid etching.

Çınar, Hasibe Gökçe; Çetin, Türkhun; İrgül, Barış
External auditory canal atresia, or congenital auditory atresia, is a birth disease marked by underdevelopment of the external auditory canal. This condition frequently leads to abnormalities in the auricle and middle ear structures, and occasionally affects the inner ear structures. It is important to note that the structures of the middle-inner ear may be impacted, although infrequently, in individuals with atresia of the external auditory canal, as was the case with our patient. Furthermore, it is crucial to emphasize the importance of early diagnosis, as it can significantly enhance the patient’s quality of life and expand their options for treatment.

Objective: One of the serious mental disorders in which people interpret reality in an abnormal situation is schizophrenia. A combination of extremely disordered thoughts, delusions, and hallucinations occurs due to schizophrenia, and the person's daily functions are seriously impaired due to this disease. For general cognitive activity analysis, electroencephalography signals are widely used as a low-resolution diagnostic tool. This study aimed to diagnose schizophrenia using the transfer learning method by including the EEGs of 73 patients diagnosed with schizophrenia, and 67 patients from the healthy group. Material and Method: In the first step of the study, digital electroencephalography signal data was converted into spectrograms to make them usable. In the classification phase, ResNet18, ResNet50 and EfficientNet models, which are FastAI, and Convolutional Neural Network (CNN) based deep learning models, were used. Results: Despite the complexity of electroencephalography data, CNN-based models in the study were successful in capturing different aspects of neurophysiological activity. The best performance was obtained from the ResNet-50 model with an accuracy rate of 97%. Afterwards, the classification process was finalized with 95% ResNet-18, and 83% EfficientNet models, respectively. Conclusion: It is thought that the classification performance of the result obtained in the application is promising, and may be a guide for future studies.

Pneumomediastinum and massive subcutaneous emphysema are clinical conditions that can occur during head and neck surgeries, bronchoscopy and tracheostomy, after thoracic trauma, rarely during dental procedures and sometimes spontaneously. Patients often present with symptoms such as swelling of the face, neck and sometimes the whole body, difficulty swallowing, shortness of breath, chest pain and skin crepitus. These findings usually develop suddenly and sometimes may occur within hours or days. A 48-year-old man is applies to the hospital with complaint chest pain due to a fall in the garden. If no pathology is thought to be present as a result of the X-ray, the patient is prescribed ibuprofen for pain relief and discharged. Patient who presents with what appears to be angioedema after taking ibuprofen is found to have pneumomediastinum. In the cases mentioned in the report and initially thought to be angioedema, seeing that the lips are not swollen and feeling subcutaneous crepitation, i.e. even just inspecting and palpating the patient, will distract the clinician from angioedema in a few seconds and direct him/her to the correct diagnosis and perform examinations in the direction of pneumomediastinum.

Eskisu, Mustafa; Doğan, Uğur
Recent studies suggest that beliefs regarding losing control may have a pivotal role in the formulation of anxiety-related problems. The Beliefs About Losing Control Inventory (BALCI) is a self-report measure that is employed to assess thought control failure. The BALCI comprises 21 items and three subscales. This study aimed to investigate the psychometric properties and measurement invariance across gender groups of the Turkish version of the BALCI. The BALCI, Obsessive Belief Questionnaire-44 (OBQ-44), Vancouver Obsessional Compulsive Index (VOCI), Anxiety Sensitivity Index-3 (ASI-3), and State-Trait Anxiety Inventory–Trait Version (STAI-T) were administered to 531 volunteer undergraduates. Confirmatory factor analysis replicated the original 21-item three-factor structure of the BALCI. Internal consistency of the BALCI total and subscales were adequate. Retest reliability for the total scores of the BALCI was .76, for the subscales varying from 0.72 to 0.78. The BALCI scores significantly correlated with OBQ-44, ASI-3, and STAI-T. The BALCI and subscales also explained a significant amount of variance in OCD symptoms above and beyond obsessive beliefs. This study also provided evidence of the measurement invariance of the BALCI across gender groups. In conclusion, the Turkish version of the BALCI is a valid and reliable instrument to assess negative beliefs regarding losing control.
