ABSTRACT

Spatially resolved capacitance-based stress self-sensing in unmodified concrete has been demonstrated. The spatial resolution is 45 mm in one dimension, which is in the direction of the capacitance measurement. Parallel coplanar component electrodes (aluminum, 5-mm wide), attached to the concrete using double-sided adhesive tape) separated by 45 mm are used to measure the in-plane capacitance in the direction perpendicular to the length of the electrodes. Combinations of component electrodes are electrically connected to form an electrode. The capacitance ranges from ∼200 pF to ∼750 pF. The greater is the number of component electrodes in an electrode, the higher is the capacitance. The compressive loading is applied at selected areas located between adjacent component electrodes. The stress (defined as load divided by the 300 ×300-mm2 concrete area) is up to 3000 Pa. The load decreases the capacitance monotonically and reversibly. The fractional decrease in capacitance ranges from ∼0.1 % to ∼0.5 %. More spatially concentrated loading, as for loading near the edges of the specimen, gives greater fractional decrease in capacitance. The capacitance decreases with increasing inter-electrode distance. Embedded steel rebars with a 20.0-mm concrete cover do not affect the capacitance or capacitance-based sensing.

ABSTRACT

There is a limited amount of data on the role of programmed cell death ligand (PD-L) -1 and PD-L2 in salivary gland carcinomas. We aimed to evaluate the prognostic value of PD-L1 and PD-L2 expressions, which are closely related to immune mechanisms, with respect to salivary gland tumor types and stages. Data from patients with salivary gland masses surgically removed between 2006 and 2021, diagnosed with a malignant salivary gland neoplasm, were retrospectively analyzed. Immunoreactivity for PD-L1 and PD-L2 was performed on resection materials. The mean age of 90 patients was 52.1±18.8 and 46.7% were male. Overall, 55.6% of patients were diagnosed with adenoid cystic carcinoma (ACC), 23.3% with mucoepidermoid carcinoma (MEC), 16.7% with acinic cell carcinoma (AciCC), 3.3% with ductal carcinoma (DC), and 1 patient with pleomorphic adenoma ex carcinoma (PA-ex-CA). In all, 52% of ACC, 12% of AciCC, 24% of MEC, and 12% of DC cases were at stage IV. The tumor diameter, frequencies of lymphovascular invasion, metastasis, positive surgical margin, recurrence, and mortality rates of patients at stages III and IV were significantly larger than those at stages I and II ( P <0.05). The percentages of tumor cell score (TCS) and immune cell score (ICS) for PD-L1 were significantly higher among patients with MEC compared with those with other types of tumors ( P =0.0011). However, the percentages of combined score (CS) for PD-L1 and tumor cell score for PD-L2 were comparable among tumor types ( P >0.05). No significant difference was found in these scores for PD-L1 between tumor stages ( P >0.05), but for PD-L2, all patients at stage I had TCS <1% for PD-L2, while all patients at stages II and III, and 92% of patients at stage IV had TCS ≥1% ( P <0.0001). High expression of PD-L1 was mostly observed in MEC cases ( P =0.0016), while all patients with AciCC had a low PD-L1 expression level ( P =0.0206). The mean tumor diameter, rate of lymphovascular invasion, perineural invasion, metastasis, positive surgical margin, recurrence, type of treatment, mortality, and TILs ratio did not differ significantly according to PD-L1 expression level ( P >0.05). The percentage of tumor-infiltrating lymphocytes was comparable among negative and positive PD-L1 scores according to both 1% and 5% threshold values ( P >0.05). High PD-L1 expression is rare in AciCC, while PD-L1 expression is high in MEC. Our findings underline the importance of future screening for PD-L1 and PD-L2 before patients undergoing immunotherapies in all salivary gland tumors.

ABSTRACT

INTRODUCTION: In this study, we investigate the effects of smoking on pain scores, vital signs, and analgesic consumption in the intraoperative and postoperative period in patients undergoing tympanomastoidectomy surgery. METHODS: A total of 100 patients with American Society of Anesthesiologists I-II status, aged 18-55 years, and who were planned to undergo tympanomastoidectomy surgery were divided into two groups: smokers (Group 1) and non-smokers (Group 2). The patients were compared for preoperative, intraoperative, and 24-hour postoperative carboxyhemoglobin, blood pressure, oxygen saturation, respiratory rate, heart rate, pain intensity and verbal numerical rating scales, the extent of patient-controlled tramadol dose, nausea, and vomiting. RESULTS: There were 50 individuals in each group. Postoperative analgesic consumption and pain scores were higher in Group 1, and the first postoperative pain was felt earlier. Furthermore, in Group 1, preoperative carboxyhemoglobin levels and postoperative nausea were statistically higher before, after, and at the tenth minute after induction, whereas oxygen saturation was lower. The two groups had no statistical difference regarding intraoperative and postoperative vital signs. Postoperative analgesic consumption was not affected by age or gender. CONCLUSIONS: Smoking changes postoperative pain management, especially for this kind of operation, and these patients feel more pain and need more postoperative analgesic doses. Therefore, effective postoperative pain control should take account of smoking behavior, and analgesic doses may need to be adjusted for patients who smoke.

ABSTRACT

BACKGROUND: Trichohepatoenteric syndrome (THES) is characterized by neonatal-onset intractable diarrhea. It often requires long-term total parenteral nutrition (TPN). In addition, other characteristic findings of the syndrome include growth retardation, facial dysmorphism, hair abnormalities, various immunological problems and other rare system findings. Two genes and their associated pathogenic variants have been associated with this syndrome: SKIC3 and SKIC2. METHODS AND RESULTS: In this case series, the clinical findings and molecular analysis results of a total of 8 patients from 5 different families who presented with persistent diarrhea and were diagnosed with THES were shared. Pathogenic variants were detected in the SKIC3 gene in 6 of our patients and in the SKIC2 gene in 2 patients. It was planned to compare the clinical findings of our patients with other patients, together with literature data, and to present yet-undefined phenotypic features that may be related to THES. In our case series, in addition to our patients with a novel variant, patient number 2 had a dual phenotype (THES and Spondyloepimetaphyseal dysplasia, sponastrime type) that has not been reported yet. Delay in gross motor skills, mild cognitive impairment, radioulnar synostosis, osteoporosis, nephropathy and cystic lesions (renal and liver) were observed as unreported phenotypic findings. CONCLUSIONS: We are expanding the clinical and molecular repertoire of the syndrome regarding patients diagnosed with THES. We recommend that the NGS (next-generation sequencing) multigene panel should be used as a diagnostic tool in cases with persistent diarrhea.

ABSTRACT

OBJECTIVE: The aim was to evaluate the vestibular system of children who had undergone cochlear implant surgery and to compare them with the healthy population by vestibulo-ocular reflex (VOR) gains in unilateral and bilateral implant users, with the implants both on and off. METHODS: Patients older than 5 years who had undergone cochlear implant surgery between 2012 and 2020 and who were cochlear implant users for at least one year were included. After consent was obtained, a video head impulse test (VHIT) was performed to evaluate the three semicircular canals, with devices on and off, and VOR gains were evaluated. VHIT was also used to assess VOR gains in the control group. The VOR gains of the study and control groups, VOR gains of unilateral and bilateral implant users, and VOR gains with implants on and off were compared. RESULTS: When the VOR gains of 24 unilateral and 13 bilateral cochlear implant users and the control group (n = 30) were compared, a significant difference was found only in the anterior semicircular canal, although the VOR gains were found to be low in all three semicircular canals in the implant users (p < 0.05). There was no significant difference between the VOR gains of unilateral and bilateral implant users. There was no significant difference between the VOR gains when either on or off. There was no correlation between cochlear implant usage time, implant insertion age, patient age and VOR gain. CONCLUSION: The effects of cochlear implant surgery on the vestibular system continue in the late period, but no correlation was observed between implant usage time and VOR gain after the first year. It was observed that having the cochlear implant on or off had no effect on VOR gain. Furthermore, bilateral implant surgery did not lead to additional vestibular dysfunction compared to unilateral implant surgery.

ABSTRACT

The Pan American Health Organization's Revolving Fund for Access to Vaccines (the Revolving Fund) is a shared pool of funds for the procurement of vaccines, syringes, and cold-chain equipment for the Member States of the Organization. With a view to evaluating the results obtained during the Revolving Fund's operation and analyzing its contributions to achievements in immunization, a review was conducted of historical documents and grey literature related to the Fund's history and current processes, as well as data from platforms fed by countries' annual reports, with reference to growth indicators, burden of vaccine-preventable diseases, introduction of new vaccines in the Region of the Americas, and lessons learned. In its 43 years of operation, the Revolving Fund has grown and contributed to the introduction of new vaccines, and the Region has made rapid progress in the field of immunization. However, several countries and territories in the Region have not yet introduced certain vaccines due to their high cost and the economic impact of sustainably administering them. The requirement to obtain the lowest possible price and to set a uniform price for all participating Member States has been instrumental in the Revolving Fund's contribution to the vaccination goals of national immunization programs, and for timely planning of demand, accompanied by technical advice. An interprogrammatic approach and the planning of auxiliary inputs are key to the success of the programs. Pandemic preparedness, regional vaccine production, and the protection of national budgets for sustainable procurement of high-cost vaccines are current and future challenges.

Com o objetivo de avaliar os resultados obtidos durante sua operação e analisar sua contribuição para os êxitos da imunização, procedeu-se a uma revisão de documentos históricos e da literatura cinzenta relacionados à história do FR e revisaram-se os processos atuais, os dados de plataformas alimentadas pelos relatórios anuais dos países, os indicadores de crescimento, a carga de doenças imunopreveníveis, a introdução de novas vacinas na Região das Américas e as lições aprendidas. Constatou-se que, em seus 43 anos de operação, o FR cresceu e contribuiu para a introdução de novas vacinas e a região avançou com rapidez no campo da imunização. Entretanto, vários países e territórios da região ainda não introduziram determinadas vacinas em razão dos altos preços e do impacto econômico de manter sua administração. A cláusula do menor preço disponível e do preço uniforme para todos os Estados Membros participantes foi fundamental para a contribuição do FR para as metas de vacinação dos programas nacionais de imunização, bem como para o planejamento oportuno da demanda acompanhado pela assessoria técnica. A abordagem interprogramática e o planejamento de insumos auxiliares são necessários para o êxito dos programas. A preparação para pandemias, a produção regional de vacinas e a proteção dos orçamentos nacionais para a compra de vacinas de alto custo e sua sustentabilidade ainda constituem desafios atuais e futuros.

ABSTRACT

Purpose: Questionnaire forms (QFs) are used in the evaluation of all patients presenting with lower urinary tract symptoms (LUTSs). Our study aims to investigate the compatibility of the three QFs with each other and to investigate the relationship between education level and complete completion of these forms. Materials and methods: A total of 224 patients between February 2018 and February 2019 were included. The patients were divided into 3 groups as primary, intermediate, and advanced according to their education level and the patients who gave incomplete answers to the questions were determined. Results: The mean age of the patients was 61.0 ± 7.57(45-85), International Prostate Symptom Score (IPSS) value was 16.2 ± 8.3(1-35), the international incontinence form-male lower urinary tract symptoms (ICIQ-MLUTS) value was 16.5 ± 7.9(0-38), the visual prostate symptom score (VPSS) value was 9.9 ± 3.0(3-16). There was a significant correlation between the three QFs (P < 0.05). The correlation between IPSS and ICIQ-MLUTS was strong (r = 0.745). The incomplete response rate was 32.1% (n = 72) in ICIQ-MLUTS, 16.5% (n = 37) in VPSS, and 10.7% (n = 24) in IPSS (P < 0.05). The incomplete response rate was not affected by education. The rate of patients who could be questioned with ICIQ-MLUTS but not with the other two QFs varied between 12.9% and 85.2%, depending on the symptoms. Conclusions: Each QF has its advantages and disadvantages. The strong correlation between IPSS and ICIQ-MLUTS found in our study indicates that these tools can be used interchangeably in daily clinical practice. ICIQ-MLUTS can evaluate symptoms that are not present in other QFs. In the evaluation of illiterate patients, VPSS should be used without any alternative.

ABSTRACT

Accurate identification of insect species is an indispensable and challenging requirement for every entomologist, particularly if the species is involved in disease outbreaks. The European MediLabSecure project designed an identification (ID) exercise available to any willing participant with the aim of assessing and improving knowledge in mosquito taxonomy. The exercise was based on high-definition photomicrographs of mosquitoes (26 adult females and 12 larvae) collected from the western Palaearctic. Sixty-five responses from Europe, North Africa and the Middle East were usable. The study demonstrated that the responders were better at identifying females (82% correct responses) than larvae (63%). When the responders reported that they were sure of the accuracy of their ID, the success rate of ID increased (92% for females and 88% for larvae). The top three tools used for ID were MosKeyTool (72% of responders), the ID key following Becker et al. [2010. Mosquitoes and their control, 2nd edn. Berlin: Springer] (38%), and the CD-ROM of Schaffner et al. [2001. Les moustiques d'Europe: logiciel d'identification et d'enseignement - The mosquitoes of Europe: an identification and training programme. Montpellier: IRD; EID] (32%), while other tools were used by less than 10% of responders. Responders reporting the identification of mosquitoes using the MosKeyTool were significantly better (80% correct responses) than non-MosKeyTool users (69%). Most responders (63%) used more than one ID tool. The feedback from responders in this study was positive, with the exercise being perceived as halfway between educational training and a fun quiz. It raised the importance of further expanding training in mosquito ID for better preparedness of mosquito surveillance and control programmes.


Title: Évaluation de l'expertise en identification morphologique des espèces de moustiques (Diptera, Culicidae) à l'aide de photomicrographies. Abstract: L'identification précise des espèces d'insectes est une exigence indispensable et difficile pour tout entomologiste, en particulier si l'espèce est impliquée dans des épidémies. Le projet européen MediLabSecure a conçu un exercice d'identification (ID) accessible à tout participant volontaire dans le but d'évaluer et d'améliorer les connaissances en taxonomie des moustiques. L'exercice était basé sur des photomicrographies haute définition de moustiques (26 femelles adultes et 12 larves) prélevées dans le Paléarctique occidental. Soixante-cinq réponses d'Europe, d'Afrique du Nord et du Moyen-Orient ont été utilisables. L'étude a démontré que les répondants étaient meilleurs pour identifier les femelles (82 % de réponses correctes) que les larves (63 %). Lorsque les répondants ont déclaré être sûrs de l'exactitude de leur ID, le taux de réussite de l'identification était meilleur (92 % pour les femelles et 88 % pour les larves). Les trois principaux outils utilisés pour les ID étaient MosKeyTool (72 % des répondants), la clé d'identification du livre de Becker et al. (38%) et le CD-ROM de Schaffner et al. (32 %), tandis que d'autres outils étaient utilisés par moins de 10 % des répondants. Les répondants déclarant identifier des moustiques à l'aide de MosKeyTool étaient significativement meilleurs (80 % de réponses correctes) que les non-utilisateurs de MosKeyTool (69 %). La plupart des répondants (63 %) ont utilisé plus d'un outil d'identification. Les commentaires des répondants de cette étude ont été positifs, l'exercice étant perçu comme à mi-chemin entre une formation pédagogique et un quiz amusant. Il a souligné l'importance d'étendre la formation complémentaire à l'identification des moustiques pour une meilleure préparation des programmes de surveillance et de contrôle des moustiques.

ABSTRACT

Lung development is impaired in mice generated through transfer of in vitro-derived blastocysts. The main objective of the current study was to determine if the composition of epithelial cells in the fetal and adult lung tissue is altered in mice generated through transfer of in vitro-derived blastocysts. The study comprised of two experimental (EGs) and two control (CGs) groups. Fetuses (18.5 d.p.c.) and adult mice (8-week-old) of the EGs (EGfetus , n=18, EGadult, n=15) were produced by the transfer of day-5 F2 blastocysts to pseudo-pregnant females. F2 fetuses and adult mice derived from naturally-ovulating females served as the CGs (CGfetus, n=18, CGadult n=15). The expression of Tuba-1a (a marker of ciliated cells), Foxj-1 (a marker of motile ciliated cells), Uch-L1 (a marker of neuroendocrine cells), Cldn-10 (a marker of Club cells), Aqp-5 (a marker of Type I alveolar cells), and Sp-C (a marker of Type II alveolar cells) was determined using western blot, immunohistochemistry/immunofluorescence and qRT-PCR analyses. Weight of fetuses as well as adult mice is decreased in mice comprising the EGs. Impaired lung development observed in EGfetus was associated with altered expression of Tuba-1a, Foxj-1, Cldn10, Uch-L1, Sp-C and Aqp-5. Morphology of the adult lung tissue was similar between the groups except for a significant increase in the thickness of the epithelia in EGadult. The expression of Cldn-10 and Sp-C was also altered in EGadult. It remains to be determined whether altered expression of these genes has any long-term impact on epithelial cell functions in the adult lung tissue.

ABSTRACT

BACKGROUND: This study aims to investigate the effect of recent influenza and pneumococcal vaccines' administration on the development of COVID-19 infection in kidney transplant recipients during the pandemic. METHODS: The effect of influenza and pneumococcal vaccines on the clinical course of the disease in COVID-positive (COVID group, n: 105) and COVID-negative (control group, n: 127) recipients has been examined. The control group included patients with negative rRT-PCR test results. At the time of the study, no patient was vaccinated with COVID-19 vaccine. The patients' influenza and/or pneumococcal vaccination rates in 2019 and 2020 were determined. In 2019 and 2020, 32 and 33 people in the COVID-positive group and 61 and 54 people in the COVID-negative group had received influenza and/or pneumococcal vaccines, respectively. The median study follow-up times of the COVID-negative and COVID-positive groups were 13.04 and 8.31 months, respectively. RESULTS: Compared with the COVID-negative group, the patients in the COVID-positive group were younger and had a longer post-transplant time. In addition, the rate of transplantation from a living donor and the rate of COVID positivity in family members were also higher. The influenza vaccination rates in the COVID negative group were significantly higher than the COVID-positive group in 2020 (23.8% vs 37%, p = 0.031). Multivariate logistic regression analysis revealed that the presence of COVID-19 in family members and lack of pneumococcal vaccination in 2020 increased the risk of being positive for COVID-19. There was no significant difference in the hospitalization rates, the need for dialysis and intensive care, the hospital stay, and the graft dysfunction in the COVID-positive patients with and without influenza and pneumococcal vaccines. CONCLUSION: The observations made throughout this study suggest that influenza and pneumococcal vaccination in transplant patients may reduce the risk of COVID-19 disease and provide additional benefits during the pandemic period.

ABSTRACT

AIMS: Biodesulfurization of fossil fuels is a promising technology for deep desulfurization. Previously, we have shown that Paenibacillus strains 32O-W and 32O-Y can desulfurize dibenzothiophene (DBT) and DBT sulfone (DBTS) effectively. In this work, improvements in DBT and DBTS desulfurization by these strains were investigated through immobilization and nanoparticle coating of cells. METHODS AND RESULTS: Paenibacillus strains 32O-W and 32O-Y immobilized in alginate gel beads or coated with Fe3 O4 magnetite nanoparticles were grown at various concentrations (0.1-2 mmol l-1 ) of DBT or DBTS for 96 h. The production of 2-hydroxybiphenyl (2-HBP) from the 4S pathway biotransformation of DBT or DBTS was measured. The highest amounts of 2-HBP production occurred at concentrations of 0.1 and 0.5 mmol l-1 . Compared to planktonic cultures maximum 2-HBP production increased by 54% for DBT and 90% for DBTS desulfurization with immobilized strains, and 44% for DBT and 66% for DBTS desulfurization by nanoparticle-coated strains. CONCLUSIONS: Nanoparticle-coated and immobilized cells may be of use in efforts to increase the efficiency of biodesulfurization. SIGNIFICANCE AND IMPACT OF THE STUDY: Alginate immobilization or nanoparticle coating of bacterial cells may be useful approaches for the enhancement of biodesulfurization for eventual use on an industrial scale.

ABSTRACT

BACKGROUND: LINCS, "Library of Integrated Network-based Cellular Signatures", and IDG, "Illuminating the Druggable Genome", are both NIH projects and consortia that have generated rich datasets for the study of the molecular basis of human health and disease. LINCS L1000 expression signatures provide unbiased systems/omics experimental evidence. IDG provides compiled and curated knowledge for illumination and prioritization of novel drug target hypotheses. Together, these resources can support a powerful new approach to identifying novel drug targets for complex diseases, such as Parkinson's disease (PD), which continues to inflict severe harm on human health, and resist traditional research approaches. RESULTS: Integrating LINCS and IDG, we built the Knowledge Graph Analytics Platform (KGAP) to support an important use case: identification and prioritization of drug target hypotheses for associated diseases. The KGAP approach includes strong semantics interpretable by domain scientists and a robust, high performance implementation of a graph database and related analytical methods. Illustrating the value of our approach, we investigated results from queries relevant to PD. Approved PD drug indications from IDG's resource DrugCentral were used as starting points for evidence paths exploring chemogenomic space via LINCS expression signatures for associated genes, evaluated as target hypotheses by integration with IDG. The KG-analytic scoring function was validated against a gold standard dataset of genes associated with PD as elucidated, published mechanism-of-action drug targets, also from DrugCentral. IDG's resource TIN-X was used to rank and filter KGAP results for novel PD targets, and one, SYNGR3 (Synaptogyrin-3), was manually investigated further as a case study and plausible new drug target for PD. CONCLUSIONS: The synergy of LINCS and IDG, via KG methods, empowers graph analytics methods for the investigation of the molecular basis of complex diseases, and specifically for identification and prioritization of novel drug targets. The KGAP approach enables downstream applications via integration with resources similarly aligned with modern KG methodology. The generality of the approach indicates that KGAP is applicable to many disease areas, in addition to PD, the focus of this paper.

ABSTRACT

Clinical relevance: Since acne vulgaris is a disease of the sebaceous glands, it may have potential effects on the ocular surface and tear homoeostasis, which are essential for good vision. Optometrists should be aware of ocular surface pathologies when prescribing glasses or contact lenses for the visual rehabilitation of these young patients.Background: To evaluate the ocular surface features, meibomian glands, and tear parameters of patients with acne vulgaris.Methods: The right eyes of 70 individuals (34 patients with acne vulgaris, 36 healthy volunteers) were evaluated. The tear break-up time of participants was measured, and the Schirmer test was performed. Then, to determine ocular surface characteristics, samples were taken from the conjunctiva for impression cytology. Finally, the loss rates of the upper and lower eyelid meibomian glands were determined by taking meibography (Sirius, CSO, Florence, Italy).Results: Tear break-up time was significantly lower in the study group compared to the control group (p < 0.001). No statistically significant difference was determined between the groups in respect of Nelson grade in the conjunctival impression cytology (p = 0.141). Grade 3 cytological changes were not observed in either group. The median value of the loss rate in the meibomian glands in the upper eyelid of patients with acne vulgaris was 19.10% (IQR: 18%), while it was 8.75% (IQR: 9.53%) in the control group (p = 0.001). The median value of the loss rate in the meibomian glands in the lower eyelid was 15.70% (IQR: 15.13%) and 7.70% (IQR: 6.53%) in the acne vulgaris and control groups, respectively (p < 0.001).Conclusion: Our study shows that patients with acne vulgaris may have a predisposition to meibomian gland damage and tear instability. Therefore, we consider that a more detailed ophthalmologic examination should be performed in patients with acne vulgaris.

ABSTRACT

BACKGROUND: Studies demonstrate that getting antioxidants in the course of treatment has a positive impact beneficial effect on fertility, especially on the quality of sperm. Because of that reason antioxidants are recommended as a potentially influential treatment for infertility in men. However, it is argued that this treatment is not based on sufficient evidence and has no effect on the rate of healthy pregnancy. OBJECTIVE: In this study, two different antioxidant combinations with different doses and contents were evaluated in terms of their effect on sperm parameters. MATERIALS/METHODS: A total of 122 patients diagnosed with idiopathic infertility were enrolled in our multicenter study. The patients were divided into two different groups: The first group used a combination 2 × 1 sachet form (l-carnitine 1 g, acetyl-l-carnitine 0.5 g, fructose 1 g, citric acid 0.50 mg, selenium 50 µg, coenzyme Q10 20 mg, vitamin C 90 mg, zinc 10 mg, folic acid 200 µg, and vitamin B12 1.5 µg) and the second group used a combination tablets form 2 × 1 (l-carnitine 500 mg, selenium 50 µg, coenzyme Q10 20 mg, vitamin C 60 mg, zinc 15 mg, folic acid 400 µg, vitamin E, and ginseng 15 µg) for 6 months. The total semen volume, the total sperm number, sperm concentration, sperm motility, and lastly morphological findings of the patients were compared at the end of 6 months. RESULTS: The mean age of the patients participating in the study was 30.8 ± 6.05 years. No significant difference was found between the two groups in terms of baseline sperm count. There was a significant difference between the baseline and sixth-month values of the patients using both combinations. However, no significant statistical difference was found between the groups according to the sixth-month data. The combinations of both antioxidants had a positive effect on sperm parameters, and the use of different doses and contents had a similar effect. CONCLUSION: Both antioxidants respectively had a positive effect on sperm parameters and also the use of different doses and contents had a similar effect.

ABSTRACT

OBJECTIVE: Osteomas are slow-growing benign osseous tumors that particularly located in the paranasal sinuses (PS). Here, we aimed to define the clinical symptoms and features, diagnostic conditions caused by osteomas located in four different PSs, to evaluate the surgical indications and methods, to compare the factors that can affect the surgical decision, radiological findings, and prognosis. METHODS: The data of patients with paranasal sinus lesions and diagnosed as osteoma according to the radiological imaging, who applied to our clinic between 2010 and 2020, were retrospectively collected and re-evaluated in the light of clinical, radiological, and pathological data. Patients who underwent surgical treatments and were definitively diagnosed as osteoma by pathology were enrolled in this study. RESULTS: We presented the data of 117 patients retrospectively. Most of these cases (n = 77, 65.8%) had an osteoma located in the frontal sinus, while 32 cases (27.4%) had osteoma in the ethmoid, two cases (1.7%) had in sphenoid and six cases (5.1%) had in maxillary sinus. We found that the presence of symptoms, diameter of osteoma, surgical indications including state of sinus drainage, and chronic/recurrent sinusitis influence the choices of physicians in management of frontal sinus osteomas. Moreover, we found a significant correlation between the grading systems defined to classify the frontal sinus osteoma to be operated (r = 0.878, 95% CI: 0.724-0.949, P<0.0001). CONCLUSION: There are several grading systems useful for the choice of surgical approaches, however, the clinical symptoms and surgical indications should not be neglected in the follow-up of patients with frontal sinus osteoma. If there are concerns about the grade of osteoma and the endoscopic approach is considered not to be sufficient for resection, the surgical procedure may be initiated endoscopically, and, if necessary, it can be combined with an external approach.
