Assessment of Stiffness-Dependent Autophagosome Formation and Apoptosis in Embryonal Rhabdomyosarcoma Tumor Cells
(2025) Sezen, S.; Adiguzel, S.; Zarepour, A.; Khosravi, A.; Gordon, J.W.; Ghavami, S.; Zarrabi, A.
Remodeling of the extracellular matrix (ECM) eventually causes the stiffening of tumors and changes to the microenvironment. The stiffening alters the biological processes in cancer cells due to altered signaling through cell surface receptors. Autophagy, a key catabolic process in normal and cancer cells, is thought to be involved in mechano-transduction and the level of autophagy is probably stiffness-dependent. Here, we provide a methodology to study the effect of matrix stiffness on autophagy in embryonal rhabdomyosarcoma cells. To mimic stiffness, we seeded cells on GelMA hydrogel matrices with defined stiffness and evaluated autophagy-related endpoints. We also evaluated autophagy-dependent pathways, apoptosis, and cell viability. Specifically, we utilized immunocytochemistry and confocal microscopy to track autophagosome formation through LC3 lipidation. This approach suggests that the use of GelMA hydrogels with defined stiffness represents a novel method to evaluate the role of autophagy in embryonal rhabdomyosarcoma and other cancer cells. © 2024.

Autoimmune Encephalitis and Musicogenic Epilepsy: a Case of Gad65 Antibody-Associated Seizure
(Wiley, 2025) Mohammadi-Asl, Ali; Bahadori, Amir Reza; Sabzgolin, Iman; Davari, Afshan; Razmafrooz, Mohammad; Tafakhori, Abbas; Ranji, Sara
Musicogenic epilepsy (ME) is a rare form of reflex epilepsy with a prevalence of 1 in 10,000,000. Recent research suggests a potential link between ME and autoimmune encephalitis, particularly involving glutamic acid decarboxylase 65-isoform (GAD65) antibodies. A 48-year-old female presented with a one-year history of music-triggered seizures. Her episodes were characterized by an initial aura followed by unresponsiveness and oral automatisms. Electroencephalography revealed abnormalities in the left anterior temporal lobe and temporal leads. Laboratory studies showed positive anti-GAD65 antibodies. The patient was treated with a combination of antiepileptic medication (Lamotrigine) and corticosteroids and intravenous immunoglobulin. This case contributes to the growing evidence supporting an association between ME and autoimmune mechanisms, particularly GAD65 antibody-mediated autoimmunity. It highlights the importance of screening autoimmune factors in ME patients and highlights the need for further research into targeted treatment strategies.
Comparison of Posterior and Antero-Lateral Renal Tumors in Retroperitoneal Laparoscopic Partial Nephrectomy: a Propensity Score Matching Analysis
(Codon Publications, 2023) Anil, Hakan; Yildiz, Ali; Guzel, Ahmet; Akdemir, Serkan; Karamik, Kaan; Arslan, Murat
This study aimed to compare the antero-lateral and posterior localized renal masses in laparoscopic partial nephrectomy with the retroperitoneal approach in terms of operative, functional, and oncological outcomes. Patients who underwent retroperitoneal laparoscopic partial nephrec-tomy by a single surgeon between January 2013 and January 2021 were included in the study. A one-to-one propensity score matching (PSM) analysis was conducted to obtain two balanced groups. The patients were divided into two groups as posterior and antero-lateral according to the localization of the mass. A total of 239 patients were included in the PSM analysis, with 65 patients allocated to each group. The mean operative time was 79.2 & PLUSMN; 11.2 min in the posterior group, while it was 90.0 & PLUSMN; 11.6 min in the antero-lateral group (P < 0.001). Warm ischemia time was 15.9 & PLUSMN; 2.4 min in the posterior group and 18.6 & PLUSMN; 2.7 min in the antero-lateral group (P < 0.001). The median decrease in eGFR at 1 year was 4.8 (IQR, 2.9-6.9) mL/min in the posterior group and 5.0 (IQR, 2.8-11) mL/min in the antero-lateral group (P = 0.219). The warm isch-emia time and clamping technique were found to be significant factors for predicting eGFR change after surgery (13:0.693, 95% CI: 0.39-0.99, P < 0.001; 13:6.43, 95% CI: 1.1-11.7, P = 0.017, respectively). We report that retroperitoneal laparoscopic partial nephrectomy provided longer warm ischemia and operative time for antero-lateral renal masses than posterior masses. However, long-term oncological and functional results were similar for both localizations.
Comparison of Three Different Modalities for the Treatment of Bladder Calculi by Size
(Sage Publications Ltd, 2022) Yildiz, Ali; Anil, Hakan; Erol, Ibrahim; Karamik, Kaan; Ercil, Hakan
Purpose: Treatment recommendations for kidney or ureteral stones are based on stone size; however, this is uncertain for bladder stones. This study aims to determine the best approach to bladder stones based on their size. Materials and methods: We retrospectively analyzed 401 patients with bladder stones. Patients were divided into three different groups according to stone size (11-20 mm, 21-30 mm, 31-40 mm as groups 1, 2, and 3 respectively). Patients had transurethral cystolithotripsy (TUCL), percutaneous cystolithotripsy (PCCL), and open cystolithotomy (OCL) performed. Results: Stone fragments were removed completely in all patients. When catheter time, postoperative stay, and hematocrit decrease values were compared, the results were significantly higher for OCL in all three groups (p: 0.001). When the relationship between stone sizes and operation time is evaluated, TUCL had shorter operation times (34.1 +/- 10.6 min) in group 1. However, TUCL had longer operation times in group 2 and group 3 compared to OCL and PCCL. Conclusion: TUCL may be preferable due to better postoperative outcomes and shorter operative time for <= 2 cm stones. As the stone size increases, PCCL is more favorable in terms of operation time.
Diagnostic Value of Shear Wave Velocity in Polycystic Ovarian Syndrome
(Medical Communications, 2021) Gursu, Turkan; Cevik, Halime; Desteli, Guldeniz Aksan; Yilmaz, Birnur; Bildaci, Tevfik Berk; Eraslan, Alper
Aim: In polycystic ovarian syndrome, the ovaries become stiffer due to chronic anovulation. We aimed to compare tissue elasticity in terms of shear wave velocities measured using acoustic radiation force impulse imaging technique between the ovaries of polycystic ovarian syndrome women and non-polycystic ovarian syndrome women. Material and methods: The study was designed as a retrospective data analysis of women who underwent transvaginal ultrasound and acoustic radiation force impulse imaging in a university hospital between July 2014 and March 2015, for various reasons. There were 32 polycystic ovarian syndrome patients and 32 patients without a diagnosis of polycystic ovarian syndrome. Age, body mass index, fasting glucose levels, cycle day 3 follicle stimulating hormone, luteinizing hormone, thyroid stimulating hormone, prolactin, antimullerian hormone levels, and menstrual patterns with clinical hyperandrogenism were evaluated. On the menstrual cycle days 2-4, by performing a transvaginal ultrasound scan, the ovarian volumes and antral follicle counts in both ovaries were recorded for each woman. The ultrasound system was converted into the elastography mode, and acoustic radiation force impulse imaging was performed. Shear wave velocity (m/sec) was measured at least 5 times for each ovary, and the mean value was calculated for each polycystic ovarian syndrome and non-polycystic ovarian syndrome woman. Results: Age, body mass index, fasting glucose levels, cycle day 3 follicle stimulating hormone, luteinizing hormone, thyroid stimulating hormone, and prolactin levels were similar between the groups (p 0,05). Antimullerian hormone levels, antral follicle counts, and mean ovarian volumes were statistically different between the groups (p <0,05). Mean shear wave velocity values for both ovaries were 2.12 +/- 0.82 (0.78-4.9) m/sec in the polycystic ovarian syndrome group, and 1.18 +/- 0.41 (0.77-2.0) m/sec in the non-polycystic ovarian syndrome group, which was statistically significantly different (p = 0.016). Conclusion: In our study, we found significantly higher shear wave velocity levels in polycystic ovarian syndrome women than non-polycystic ovarian syndrome women, which indicates an impact of the condition on shear wave velocity. The increased acoustic frequencies cause a decreased response in time to transition, and motion becomes out of phase; in other words, scattered waves are faster in stiffer ovaries. Our results are thus compatible with the pathophysiology of the disease. Shear wave velocity is a beneficial tool for evaluating ovarian elasticity in polycystic ovarian syndrome patients in whom the levels are found to be significantly higher than non-polycystic ovarian syndrome women. In light of these findings, shear wave velocity is expected to be slower than polycystic ovarian syndrome levels in ovulatory women.
Diagnostic Value of Voiding Scores of the "International Prostate Symptom Score" and the "Bristol Female Lower Urinary System Symptoms-Short Form" Questionnaires in Women With Voiding Dysfunction
(Wolters Kluwer Medknow Publications, 2024) Erbay, Mehmet Erkan; Sevinc, Burcu Hanci; Tarhan, Fatih
Introduction:We aimed to investigate the diagnostic value of International Prostate Symptom Score voiding symptom score (IPSS-VS) and Bristol Female Lower Urinary Tract Symptoms-short form voiding score (BFLUTS-VS) in female patients with urodynamically diagnosed voiding dysfunction. Methods:The medical records of female patients who underwent urodynamic examination between May 2007 and November 2021 for lower urinary tract complaints were retrospectively evaluated. A total of 1858 female patients were included in the study. Patients investigated between 2007 and 2014 were asked to fill the IPSS, and patients investigated after 2015 were asked to fill the BFLUTS-SF. Results:The mean age of the patients was 49.06 0.33 in the IPSS group and 50.02 +/- 0.47 in the BFLUTS group. On the pressure flow study, voiding dysfunction was found in 14.8% (n = 95) in the IPSS group and 15.1% (n = 183) in the BFLUTS group. The area under curve value was found to be 0.58 for IPSS and 0.64 for BFLUTS. Threshold values were found as >9 for IPSS-VS and >4 for BFLUTS-VS. The sensitivity, specificity, false negative, and false positive rates for IPSS-VS were 33.3%, 78.8%, 66.7%, and 21.2%, respectively. The same parameters were 45.5%, 78.9%, 54.5%, and 21.1% for BFLUTS-VS, respectively. Conclusion:The diagnostic performance of both the questionnaires was found to be low for diagnosing voiding dysfunction in female patients according to our data. Therefore, the assessment of the voiding phase in women should not solely rely on the current questionnaires. However, further studies using questionnaires including all voiding symptoms are required.
Do External Female Genital Measurements Affect Genital Perception and Sexual Function and Orgasm
(Galenos Yayıncılık, 2020) Kaya, Aski Ellibes; Dogan, Ozan; Yassa, Murat; Basbug, Alper; Ozcan, Canan; Caliskan, Eray
Objective: To provide baseline data for the anatomy of the external female genitalia and to investigate the correlation between those measurements and sexual function and genital perception. Materials and Methods: This prospective cohort study consisted of 208 healthy premenopausal women. The Female Sexual Function index (FSFI) and the Female Genital Self-image scale (FGSIS) questionnaires were administered. Participants were divided into two groups according to their female sexual dysfunction (FSD) status. External genital measurements and anterior and posterior vaginal length were measured. Results: The external female genital measurements were (cm, mean +/- standard deviation): clitoral prepuce length 2.05 +/- 0.48; clitoral glans length 0.87 +/- 0.21; clitoral glans width 0.60 +/- 0.15; clitoris to urethra 2.24 +/- 0.55; anterior fornix depth 7.75 +/- 0.92; posterior fornix depth 9.25 +/- 0.75; labia minora width, right 2.12 +/- 0.86, left 2.20 +/- 0.96. A weak negative correlation was found between total FGSIS scores and clitoral prepuce length (p=0.01, r=-0.17), whereas a weak positive correlation was seen between total FGSIS scores and anterior-posterior vaginal lengths (p=0.04, r=0.13; p=0.02, r=0.15, respectively). No statistically significant difference was found between the genital measurements of participants with FSD (n=82, 39.4%) and those without FSD (n=126, 60.6%), and the total FSFI scores and orgasm subdomain scores. Conclusion: The female genital measurements were found to be distributed over a wide range. Although the relationship between genital measurements and genital perception varied, no significant relationship was found between genital measurements and sexual functions or orgasm. These findings suggest that a more cautious approach should be taken towards genital surgeries for cosmetic purposes.
Does Transition From Standard To Retzius-Sparing Technique in Robot-Assisted Radical Prostatectomy Affect the Functional and Oncological Outcomes
(Pagepress Publ, 2021) Anil, Hakan; Karamik, Kaan; Yildiz, Ali; Savas, Murat
Objective: To appraise the outcomes on the Retzius-sparing robot-assisted radical prostatectomy (Rs-RARP) learning curve of a surgeon with previous experience of anterior (standard) RARP. Materials and methods: The first 50 cases during the Rs-RARP learning curve (group 1) and 50 cases after the second 100 cases with the standard approach (group 2) were comprised in the study. Patients who used zero or one safety pads were considered continent. Erectile function recuperation was characterized as the competence to achieve penetrative intercourse without receiving any medication. All patients were reevaluated at two weeks, first, third, sixth, and 12th months after surgery using LIEF-5, PSA level, and continence status. Results: Immediate continence rates following catheter removal were 32/50 (64%) in Rs-RARP group and 26/50 (52%) in S-RARP group (p = 0.224). The continence recovery rate was 48/50 (96%) in Rs-RARP group and 46/50 (92%) in the S-RARP group at 12 months follow-up (p = 0.400). Total nerve-sparing surgery was enforced in 36/50 (72%) patients for group 1 and 35/50 (70%) patients for group 2. Potency recovery was 27/43 (62.8%) in Rs-RARP and 30/44 (68.2%) for S-RARP at 12 months follow up (p = 0.597). Surgical margin positivity was detected in 6/50 (12%) cases in the Rs-RARP group and in 4/50 (8%) cases in the S-RARP (p = 0.444). Conclusions: Functional and oncological results are not negatively affected in the first 50 cases for a surgeon who is experienced in S-RARP before transition to the Rs-RARP method.
The Effect of Topiramate on the Cerebellum of the Obese Female Rats: a Stereological, Histochemical and Bioinformatical Study by Investigation of Tnf-Α Interaction
(Wiley, 2025) Alkan, Isinsu; Altunkaynak, Berrin Zuhal; Akbari, Amir Mahdi; Altun, Ceren Erdem; Baycu, Cengiz
The rising incidence of obesity underscores the necessity for alternative obesity treatments. Patients commonly prefer medication aiding in weight reduction. Topiramate, an antiepileptic drug, is gaining popularity among obese patients for its weight loss benefits. This study aims to explore Topiramate's impact on the cerebella of obese female rats. In the experiment, 24 female rats (200-250 g) were divided into four groups: non-obese control (NOC), obese control (OC), non-obese topiramate (NOT) and obese topiramate (OT). The non-obese rats were given a standard diet, while the obese rats received a high-fat diet (40% fat). After 9 weeks, topiramate was administered intraperitoneally daily for 6 weeks. Following this, the rats were euthanised, and their cerebella were removed. The volume of the cerebellum and mean numerical density of the molecular neurons, granular neurons and Purkinje cells were estimated using stereological methods, and the link between obesity-caused cerebellum damage and TNF-alpha was assessed through immunohistochemical and bioinformatic techniques. Additionally, histopathological evaluations of the tissues were conducted. The cerebellar volume in the OC group was decreased compared to the NOC group. The topiramate groups exhibited a decrease in molecular or/and granular neuron numbers in the NOT and OT groups. Notably, neurons with dark cytoplasm were observed in the topiramate-treated groups, alongside neuronal degeneration was seen in the obese groups. The connection between TNF-alpha and obesity or obesity-caused cerebellum damage was confirmed through both immunohistochemical and bioinformatics analyses. These findings suggest that topiramate might have a degenerative effect on the cerebellum, especially following obesity.
Endovascular Treatment of Hepatic Arterioportal Fistula Complicated With Giant Portal Vein Aneurysm Via Percutaneous Transhepatic Us Guided Hepatic Artery Access: a Case Report and Review of the Literature
(Springernature, 2019) Oguslu, Umut; Uyanik, Sadik Ahmet; Gumus, Burcak
BackgroundHepatic arterioportal fistulas are rare, abnormal, direct communications between hepatic artery and portal venous system. Treatment options shifted from surgery to endovascular interventions. Catheterization may be challenging. We report a case of a hepatic arterioportal fistula treated successfuly with Amplatzer Vascular Plug II via percutaneous transhepatic hepatic artery access after failed transfemoral approach.Case presentation58year old woman presented with right heart failure, kidney insufficiency and massive ascites related to portal hypertension caused by hepatic arterioportal fistula. She had a history of previous abdominal surgery. Colour Doppler ultrasound and computed tomography revealed a giant portal vein aneurysm related to large hepatic areterioportal fistula. Endovascular treatment was planned. Catheterization of the hepatic artery could not be realized due to severe tortuosity and angulation of the celiac artery and its branches. Access to the hepatic artery was obtained directly via percutaneous transhepatic route and fistula site was embolized with Amplatzer Vascular Plug II and coils. Immediate thrombosis of the aneurysm sac and draining portal vein was observed. Patients clinical status improved dramatically.ConclusionTranscatheter embolization is the first choice of the treatment of hepatic arterioportal fistulas but the type of the therapy should be tailored to the patient and interventional radiologist should decide the access site depending on his own experience if the routine endovascular access can not be obtained.
Evaluation of the Effects of Orthopedic Treatment on the Dentofacial Structure and Upper Airway of Subjects With Skeletal Class Iii Malocclusion
(Galenos Publishing House, 2024) Kan, H.; Sözen, T.; Öğretmenoğlu, O.; Ciğer, S.
Objective: The present study aimed to evaluate the effect of rapid maxillary expansion (RME) and face mask treatment on the upper airway in patients with maxillary retrusion in two dimensions using digital cephalograms and volumetric evaluation using acoustic rhinometric measurements. Methods: A total of 22 individuals with a concave profile and skeletal and dental Class III malocclusion during growth and development with a mean age of 9.9±1.38 years were included in the study. A bonded RME appliance and a petit face mask were adapted for the patients. Before treatment (T0) and after maxillary protraction (T1), lateral cephalometric films and acoustic rhinometric recordings were obtained. The dependent sample t-test was used for statistical evaluation. Results: Cephalometric analysis revealed forward movement of the maxilla and backward downward rotation of the mandible. A significant increase was observed in the nasopharyngeal and oropharyngeal regions of the upper airway. Three-dimensional evaluation of the upper airway by acoustic rhinometry revealed only an increase in the volumes of the left nasal cavity after decongestant administration. A statistically significant increase in acoustic rhinometric measurements in nasal valves. When the correlation of the cephalometric findings of the nasopharyngeal region with the acoustic rhinometry findings was examined, no statistically significant relationship was found. Conclusion: As a result of this study, we observed an increase in the cephalometric measurements of the nasopharyngeal and oropharyngeal areas. A significant increase was observed in the minimal cross-sectional area measured by acoustic rhinometry. Copyright© 2024 The Author.
Extraperitoneal Laparoscopic Versus Transperitoneal Robot-Assisted Laparoscopic Approaches for Extended Pelvic Lymph Node Dissection During Radical Prostatectomy
(Mary Ann Liebert, inc, 2022) Yildiz, Ali; Anil, Hakan; Akdemir, Serkan; Aksaray, Eren Erdi; Ates, Mutlu; Arslan, Murat
Background: We aim to directly compare the feasibility and safety of extended pelvic lymph node dissection (PLND) during transperitoneal robotic-assisted radical prostatectomy (Tp-RARP) and extraperitoneal laparoscopic radical prostatectomy (Ep-LRP). Materials and Methods: We retrospectively identified the prospectively maintained database records of 162 patients diagnosed with prostate cancer (PC) who underwent Ep-LRP or Tp-RARP with extended PLND. Patients with risk of nodal metastases over 5% according to Briganti nomogram received extended PLND. All data analyzed in this study were based on the documentation in our PC database including age, body mass index, Charlson comorbidity index score, preoperative prostate-specific antigen, history of abdominal surgery, biopsy Gleason score, total operation time, postoperative pelvic drainage time, pathological results, lymph node yield (LNY), percentage lymph node involvement (%LNI), and perioperative complications. Patients were followed up for biochemical recurrence in the postoperative period. Results: Eighty-two of the 162 enrolled patients were in group 1 (Ep-LRP+PLND) and 80 were in group 2 (Tp-RARP+PLND). There were no statistically significant differences between the groups regarding preoperative demographics and clinical characteristics. The median LNY was 17 (range 8-27) and 17.5 (range 10-29) in groups 1 and 2, respectively, and no statistically significant difference was found. There was no significant difference between the groups in terms of biochemical recurrence-free survival with mean follow-up of 44.8 months after radical surgery. Conclusion: Our results support the view that extended PLND through the Ep-LRP approach is a feasible and safe procedure without compromising oncological efficacy compared with a similar template attempted during Tp-RARP. Clinical Trial Registration number is 01/21-2.
Human Papilloma Virus Frequency and Genotypes; Evaluation of the 4879 Screenings Made With Polymerase Chain Reaction and Chip Array Between 2001 and 2019 in Istanbul
(Kare Publ, 2021) Vural, Gurcan; Polat, Nedim
Objectives: The aim of this study is the documentation of human papilloma virus (HPV) frequency and types seen in the city of Istanbul, Turkey, as well as evaluation of the relationship between these subtypes and cytological and pathological diagnoses. Methods: 4879 cases were studied in our molecular pathology department between 2001 and 2019 in Istanbul. Between 2001 and 2010, 1692 cases were screened for HPV 6, 11, 16, 18, 31, and 33 by conventional hybridization and polymerase chain reaction (PCR). Since 2011, up to 49 HPV typing has been performed for 3187 cases with chip array. The cases were referred to the pathology center and the hospital pathology department by clinicians for screening before HPV vaccination and on the observation of precancerous changes and koilocyts in cytological-histopathological evaluations. Results: In this study, the frequency of HPV was found to be 10.8% (527 HPV-positive cases). Among these, 348 cases were high-risk groups, whether or not they were previously associated with a low-risk group. When we look at the distribution of the cases according to the high-risk HPV types, HPV 16 is the most common type. The frequencies of occurrence of other HPV types are as following: HPV-16: 41.7%, HPV-31: 11.7%, HPV-52: 7.9%, HPV-51: 7.1%, HPV-33: 6.9%, HPV-45: 6.5%, HPV-18: 6.3%, HPV-39: 6.1%, and HPV-58: 5.8%. It was further found that multiple infections were 28% of high grade squamous intraepithelial lesion cases. HPV frequency was 38% and 72%, respectively, in cases with cytologically or histopathological precancerous, low-grade squamous intraepithelial lesion, and HSIL changes. As a final note, HPV was detected in 9 of 10 cases with cervical cancer (90%). Only 1 adenocarcinoma case detected in the series was a double infection with HPV types 18 and 45. Conclusion: HPV 16 was the most common type found in this study. It is followed by types 31, 52, 51, 33, 45, 18, 39, and 58, respectively. The most common association observed in double infections was between HPV 16 and 58. It was also observed that the incidence of HPV in the city of Istanbul, Turkey, was similar to other developed countries. As a final note, in addition to screening tests, PCR and chip array studies should be conducted and the community should be informed about preventive medicine and the importance of condom use.

The Positive Effects of Preoperative Chlorhexidine Rinse To Reduce Postoperative Pneumonia After Kidney Transplantation Surgery
(Royal College Surgeons Edinburgh, 2025) Ferhatoglu, Murat Ferhat; Sahin, Osman Z.; Kivilcim, Taner; Gurkan, Alp
Background: Postoperative pneumonia is one of the most observed hospital-acquired infections and increases the postoperative mortality rate. Further, it drives the healthcare systems under a severe financial burden. Preventing postoperative pneumonia is an incredibly challenging issue for clinicians. Since immunosuppression therapy, the patients who had kidney transplants are more vulnerable to postoperative infections. There is no data in the scientific literature focusing on the effects of preoperative oral care with chlorhexidine antiseptic solutions on postoperative pneumonia in kidney transplantation surgery cases. In the present research, we studied this topic. Methods: A prospective, randomized clinical trial was conducted at our institution between August 2020 and August 2022. Group A: Received 0.12 % chlorhexidine oral rinse preoperatively; Group B: Not received 0.12 % chlorhexidine oral rinse preoperatively. We analyzed the differences between the two trial groups using a chi-square or t-test. The Mann-Whitney U test was used for the categorical data. Results: Nine patients (17.6 %) were diagnosed with postoperative pneumonia in Group A and fourteen (25.9 %) in Group B (p < 0.05). Hospitalization time of Group B was prolonged (p < 0.05). In multivariate analysis, significant risk factors associated with postoperative pneumonia were advanced age, diabetes mellitus, smoking, delayed graft function and not gargling with 0.12 % chlorhexidine (p < 0.05). Conclusions: To reduce postoperative pneumonia risk in patients undergoing kidney transplantation surgery, an oral health protocol including 0.12 % chlorhexidine mouth rinse seems beneficial.

(Elsevier, 2022) Cinier, Goksel; Hayiroglu, Mert Ilker; Cinar, Tufan; Pay, Levent; Yumurtas, Ahmet Cagdas; Tezen, Ozan; Gurkan, Kadir
Implantable cardioverter defibrillators (ICD) are recommended in heart failure with reduced ejection fraction (HFrEF) patients to reduce arrhythmic deaths. This study aimed to identify risk factors associated with mortality within one-year following the ICD. The data from our hospital's electronic database system was extracted for patients who were implanted ICD secondary to HFrEF between 2009 and 2019. Overall, 1107 patients were included in the present analysis. Mortality rate at one-year following the device implantation was 4.7%. In multivariate analysis; age, atrial fibrillation, New York Heart Association classification >2, blood urea nitrogen, pro-brain natriuretic peptide and albumin independently predicted one year mortality.(c) 2022 Cardiological Society of India.

Primary Failure of Eruption: a Rare but Desperate Condition for Orthodontic Treatment
(Galenos Publ House, 2025) Soz, Yaren; Savkan, Ipek; Biren, Sibel; Acar, Zeynep Ahu
Tooth eruption is a highly complex mechanism that is controlled by many factors. Various mechanical, systemic, or genetic factors can cause eruption disorders. Primary failure of eruption (PFE) is known as an eruption disorder occurring due to non-syndromic genetic factors. It is frequently seen in the first and second molars and causes posterior open bite. It can be observed unilaterally or bilaterally. Studies show that mutations in many different genes that control the tooth eruption mechanism, mainly the PTH1R and KMT2C genes, constitute the genetic basis of PFE. Primary eruption disorders are very difficult to treat. It is known that the application of active orthodontic forces causes local ankylosis in the tooth and the failure of the tooth to return to its normal position. For this reason, determining the correct diagnosis and treatment method is very important. Although there are different treatment methods, the results of research about the success of these treatment methods are quite limited. This review aims to explain the etiology, diagnosis, and treatment of PFE in light of current genetic studies.
Tolerability To Paracetamol and Preferential Cox-2 Inhibitors in Patients With Cross-Reactive Nonsteroidal Anti-Inflammatory Drugs Hypersensitivity
(Asia Pacific Assoc Allergy, Asthma & Clinical Immunology, 2020) Terzioglu, Kadriye; Sancar, Ozgur; Ekerbicer, Hasan Cetin; Ozturk, Raziye Tulumen; Epozturk, Kursat
Background: Acetylsalicylic acid/aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used drugs that may cause hypersensitivity reactions in a substantial proportion of patients. Physicians ought to be aware of these situations. Objective: We aimed to present the clinical characteristics and rates of tolerability to cyclooxygenase (COX)-2 inhibitor analgesics in patients who had admitted due to multiple cross-reactive type of NSAID hypersensitivity. Methods: The files of the patients who had admitted with multiple NSAIDs-induced symptoms were investigated retrospectively. Age, sex, underlying diseases, clinical manifestation, skin test results, and drug provocation test results were analyzed. Results: In 105 patients with multiple cross-reactive type of NSAID hypersensitivity, we found the rate of cross-reactivity to any of the relatively safe alternatives including paracetamol, meloxicam, and nimesulide to be 16.1%. The rate of cross-reactivity to these relatively safe drugs was significantly higher in patients with a history of anaphylaxis induced by NSAID intake (p= 0.006). Conclusion: The diagnosis of COX-1-mediated multiple NSAID hypersensitivity can be often established with a detailed history. Although rare, severe hypersensitivity reactions may be observed in these patients. Undesired situations for both patients and physicians may be avoided by testing relatively safe paracetamol and COX-2 inhibitors in experienced centers.
An Updated Comparison of Current Impression Techniques Regarding Time, Comfort, Anxiety, and Preference: a Randomized Crossover Trial
(Aves, 2021) Yilmaz, Hakan; Konca, Fatma Asli; Aydin, Merve Nur
Objective: To compare digital and conventional impressions in terms of impression time, and comfort, anxiety, and preference of the patients. Methods: Digital scans (Trios 3 Cart) and conventional impressions (irreversible hydrocolloid material, hand-mixed) were randomly performed on 39 patients by a single experienced operator at 14-21-day intervals (crossover design). The impression time, comfort score with the visual analog scale, anxiety level with the State-Trait Anxiety Inventory, and preference with a questionnaire, were recorded. The 2 techniques were compared with the independent t-test in terms of time, comfort, and anxiety. Patient-operator assessment and time-comfort relationship were analyzed using Pearson's correlation test. Results: No statistical difference was found between the 2 impression techniques in terms of time (P = .231). Both the operators' and patients' comfort scores showed that the digital technique was found to be more comfortable (P < .001). There was no statistical difference between the 2 techniques with regard to anxiety (P = .668). The patients' and operators' comfort scores showed a strong correlation (P < .001), but no correlation was found between comfort and time (P > .05). Conclusion: Digital scanning and conventional dental impression were similar in terms of impression time and anxiety of patients. However, patients were more satisfied with the digital technique, and preferred it.

OBJECTIVE: The aim was to investigate the validity and reliability of the Turkish version of the Modified Medical Research Council (mMRC) Dyspnea Scale in Systemic Sclerosis (SSc) patients with Interstitial Lung Disease. MATERIAL AND METHODS: Thirty patients diagnosed with SSc according to the 2013 EULAR/ACR criteria were included. After recording the demographic data of the patients, dyspnea was evaluated with the Visual Analogue Scale (VAS), exercise capacity with the 6 Minute Walk Distance (6MWD), fatigue level with the Fatigue Severity Scale (FSS), disease activity with the Medsger Disease Severity Scale, skin involvement with the Modified Rodnan Skin Score, and dyspnea level with the mMRC Dyspnea Scale. The mMRC Dyspnea Scale was administered to the patients with SSc who did not receive any treatment for test-retest reliability at 1-week intervals. RESULTS: The observed scale range in mMRC (TR) was 0-4, and twelve out of the thirty patients (40%) were classified as having "moderate dyspnea." mMRC (TR) showed a significant moderate positive correlation with VAS dyspnea (rho: 0.718), a low negative correlation with 6MWD (rho: -0.445), and a low positive correlation with FSS (rho: 0.385). The weighted kappa statistic, used as an agreement scale for ordinal responses, was found to be 0.587 (indicating moderate agreement). CONCLUSION: The Turkish version of the mMRC Dyspnea Scale demonstrates validity and reliability in SSc patients with interstitial lung disease.
