RESUMO
Abstract Objective: The prognostic importance of minichromosome maintenance complex expression in nasopharyngeal cancer is still unknown. We aimed to find whether minichromosome maintenance complex 2-7 expression may potentially be used to predict the prognosis of nasopharyngeal cancer patients treated with definitive radiotherapy. Methods: Between April 2007 and July 2020, patients with nasopharyngeal cancer treated with radiotherapy were identified. Immunohistochemical analysis was performed on formalin-fixed paraffin-embedded tissues of cases. A single pathologist analyzed the histologic specimens of all patients. Results: Totally, 67 patients were included. The median followup was 75.3 months. Higher tumor (T) stage was correlated with minichromosome maintenance complex 2 overexpression. Minichromosome maintenance complex s expression was also associated with histopathologic subgroups. According to univariate analysis, AJCC stage, histopathological subgroups, tumor response after treatment, minichromosome maintenance complex 2, 3, 5, 6 and 7 expression were the prognostic factors that predict overall survival. According to multivariate analysis minichromosome maintenance complex 7 expression was the only prognostic marker for both progression-free survival and overall survival. Conclusion: The overexpression of minichromosome maintenance complex 2, 3, 5, 6 and 7 indicated bad prognosis. Minichromosome maintenance complex 7 was an independent prognostic factor for survival outcomes in nasopharyngeal cancer and may be a potential therapeutic target for treatment.
RESUMO
INTRODUCTION: Pulmonary actinomycosis, clinically and radiologically, mimics abscess, tuberculosis, and lung malignancy, resulting in misdiagnosis or delay in diagnosis. In this study, we analyzed the clinicoradiological features of pulmonary actinomycosis, the presence of any differences between clinical prediagnosis and radiological diagnosis, and whether imaging modalities help distinguish pulmonary actinomycosis from lung cancer. METHODS: A total of 22 patients who had a histopathological diagnosis of actinomycosis in a tertiary health center participated in this study. Of these, 14 had positron-emission tomography/computed tomography. RESULTS: In all, 81.8% of the patients were males. The diagnostic procedures employed for the diagnosis of actinomycosis were surgery in 54.5% of patients, fiberoptic bronchoscopy in 36.4% of patients, and rigid bronchoscopy in 9.1% of patients. Radiological and clinical prediagnosis showed malignancy in 31.8 and 40.9% of patients, respectively. The mean of the maximum standardized uptake value was 6.33±3.6 on positron-emission tomography/computed tomography. Kappa compliance analysis revealed that clinical and radiological diagnoses were significantly compatible with each other and that radiological pre-diagnoses were not superior to clinical diagnoses (κ=0.701 and p<0.001). CONCLUSION: Pulmonary actinomycosis shows high metabolic uptake in positron-emission tomography/computed tomography, and this may mislead clinicians for a diagnosis of malignancy. Our results suggest that positron-emission tomography/computed tomography does not help distinguish pulmonary actinomycosis from lung malignancy and does not provide a clear diagnostic benefit to the clinician, so pathological diagnosis is necessary.

Objective: Dentists need a high level of awareness to limit the spread of COVID-19 (Coronavirus disease 2019). This study aimed to evaluate the level of awareness and attitude regarding the risk associated with dental procedures among dentists. Material and Methods: An online questionnaire was submitted to dentists between April- May 2020. The questionnaire form included questions related to demographic data, the transmission characterization of SARS-CoV-2, and treatment of COVID-19 patients. Data were analyzed using IBM SPSS V23 and chi-square test (p ≤ 0.05). Results: A total of 3825 participants (29.1± 7.6 years) were included. In COVID-19, the riskiest dental branch in terms of the risk of contamination through saliva was considered to be Periodontics (32.2%), while the least risky branch was Orthodontics (0.2%). Specific dental treatment procedures considered at high risk of contamination were tooth preparation (69.4%), scaling and root planing (63.5%), filling (53.4%), and pulpectomy (40.5%). The parameters of the study that differed according to gender and professional status were the viability of the virus, the risk assessment, saliva contamination risk, and aerosol-generating activities for COVID-19 (p < 0.05). Conclusion: Dentists were aware of the risk assessment and extra precautionary methods. However, they had limited knowledge about the viability of the virus. Dentists should be aware of recommended approaches and update their knowledge about COVID-19 to limit the spread of the disease. Since dentistry is an area suitable for the transmission of the COVID-19, the fact that dentists have information about the viability of this virus will be lifesaving in clinical applications (AU)
Objetivo: Os dentistas precisam de um alto nível de conhecimento para limitar a disseminação de COVID-19 (doença por coronavírus 2019). Este estudo teve como objetivo avaliar o nível de consciência e atitude em relação ao risco associado aos procedimentos odontológicos entre os dentistas. Material e Métodos: Um questionário online foi submetido aos dentistas entre abril e maio de 2020. O formulário do questionário incluía questões relacionadas aos dados demográficos, à caracterização da transmissão da SARS-CoV-2 e ao tratamento de pacientes com COVID-19. Os dados foram analisados usando IBM SPSS V23 e teste do qui-quadrado (p ≤ 0,05). Resultados:Um total de 3825 participantes (29,1 ± 7,6 anos) foram incluídos. Na COVID-19, o ramo odontológico de maior risco em termos de risco de contaminação pela saliva foi considerado a Periodontia (32,2%), enquanto o ramo de menor risco foi a Ortodontia (0,2%). Os procedimentos odontológicos específicos considerados de alto risco de contaminação foram preparo dentário (69,4%), raspagem e alisamento radicular (63,5%), obturação (53,4%) e pulpectomia (40,5%). Os parâmetros do estudo que diferiram de acordo com sexo e status profissional foram a viabilidade do vírus, a avaliação de risco, risco de contaminação da saliva e atividades geradoras de aerossol para COVID-19 (p <0,05). Conclusão: Os dentistas estão cientes da avaliação de risco e dos métodos de precaução extra. No entanto, eles tinham conhecimento limitado sobre a viabilidade do vírus. Os dentistas devem estar cientes das abordagens recomendadas e atualizar seus conhecimentos sobre COVID-19 para limitar a propagação da doença. Como a odontologia é uma área propícia para a transmissão da COVID-19, se dentistas tiverem informações sobre a viabilidade desse vírus poderão salvar vidas em aplicações clínicas. (AU)

ABSTRACT Objective: It has been reported that phosphodiesterase-5 (PDE-5) inhibitors improve kidney function during acute and chronic renal failure. This study aimed to determine the possible therapeutic effects of tadalafil, a specific PDE-5 inhibitor, on renal fibrosis induced by unilateral ureteral obstruction (UUO). Methods: Male Sprague-Dawley rats were used and randomly divided into three groups (n = 6) as sham-operated, UUO and tadalafil-treated (10 mg/72 hours, ig) UUO (UUO+T) groups. Unilateral ureteral obstruction was induced by complete ligation of the left ureter and 14 days after surgery creatinine clearance, urinary cyclic guanosine monophosphate (cGMP), renal alpha-smooth muscle actin (α-sma) and transforming growth factor βeta (TGF-β) levels, as well as histologic changes, were observed in all the animals. Results: Unilateral ureteral obstruction-induced renal fibrosis was confirmed by increased α-sma level, collagen deposition, tubular dilation, inflammatory cell infiltration and necrosis. An increased renal TGF-β level and decreased urinary cGMP level was also observed in obstructed animals in addition to reduced creatinine clearance. Tadalafil treatment, which restored the animals 'urinary cGMP level, significantly attenuated the fibrotic changes and TGF-β increase in their kidneys. Conclusion: This study suggests that tadalafil treatment ameliorates renal fibrosis by reducing TGF-β expression and may have important clinical relevance since tadalafil is currently used clinically to treat erectile dysfunction and pulmonary hypertension.
RESUMEN Objetivo: Se ha reportado que los inhibidores de la fosfodiesterasa-5 (PDE-5) mejoran las funciones renales durante la insuficiencia renal aguda y crónica. Este estudio tuvo por objetivo determinar los posibles efectos terapéuticos del tadalafil - un inhibidor específico de la PDE-5 - sobre la fibrosis renal inducida por una obstrucción ureteral unilateral (OUU). Métodos: Se utilizaron ratas machos Sprague-Dawley, divididas de manera aleatoria en tres grupos (n = 6): operación simulada, OUU y tratamiento con tadalafil (10 mg/72 horas, IG), y OUU (OUU+T). La obstrucción uretral unilateral fue inducida por una ligadura completa del uréter izquierdo y 14 días después de la cirugía, se observaron niveles de monofosfato de guanosina cíclico (GMP) urinario, alfa-actina de músculo liso (α-SMA), y factor de crecimiento transformante βeta (FCT-β), así como cambios histológicos en todos los animales. Resultados: La fibrosis renal inducida por obstrucción uretral unilateral fue confirmada por un aumento del nivel de α-SMA, deposición de colágeno, dilatación tubular, infiltración de células inflamatorias y necrosis. También se observó un aumento del nivel de FCT-β renal y una disminución del nivel de GMP urinario en los animales con obstrucción, además de una reducción del aclaramiento de la creatinina. El tratamiento con tadalafil, que restauró el nivel de GMP urinario de los animales, atenuó significativamente los cambios fibróticos y el aumento de FCT-β en los riñones. Conclusión: Este estudio sugiere que el tratamiento con tadalafil mejora la fibrosis renal al reducir la expresión de FCT-β y puede tener una importante relevancia clínica por cuanto el tadalafil se usa hoy día clínicamente para tratar la disfunción eréctil y la hipertensión pulmonar.

OBJECTIVES: We examined the effects of tadalafil, one of the phosphodiesterase type 5 (PDE5) inhibitors, in a rat model of with partial and complete unilateral ureteral obstruction (UUO). METHODS: The rats were divided into 5 groups: sham (n=6), partial unilateral ureteral obstruction (PUUO, n=6), PUUO with tadalafil treatment (PUUO+T; Cialis, 10 mg/72 h, intragastric; Lilly, Indianapolis, Indiana, USA), complete unilateral ureteral obstruction (CUUO, n=6), and CUUO with tadalafil treatment (CUUO+T). RESULTS: Fifteen days after the UUO, the ureter presented changes in the layers of urothelium and significant infiltration of inflammatory cells in the PUUO and CUUO groups. Compared with the sham, PUUO and CUUO groups had severe increased inflammatory cell infiltration. The urothelial epithelium exhibited cell degeneration and loss because of the swollen, atrophic, and denuded epithelial cells in the PUUO and CUUO groups. In the PUUO+T and CUUO+T groups, the urothelium revealed less epithelial cell degeneration and loss.The expressions of α-smooth muscle actin (α-SMA) and transforming growth factor-ß (TGF-ß) exhibited up-regulation in the PUUO and CUUO groups. The expression of TGF-ß decreased positively correlated with that of α-SMA in the tadalafil therapy groups, PUUO+T and CUUO+T. CONCLUSION: The phosphodiesterase type 5 inhibitor's tadalafil reduced expressions of α-SMA and TGF-ß in the obstructed ureters, measured by biochemical examinations. In addition, tadalafil decreased urothelium degeneration due to the decreased epithelial cell loss and inflammatory cell infiltration. Our results show that tadalafil prevents or slows down the onset of ureter inflammation and urothelial degeneration in rats with UUO.

RESUMO OBJETIVOS: Examinamos os efeitos do tadalafil em um dos inibidores da fosfodiesterase tipo 5 (PDE5) em um modelo de rato com obstrução ureteral unilateral parcial e completa (UUO). MÉTODOS: Os ratos foram divididos em cinco grupos: sham (n = 6), obstrução ureteral unilateral parcial (PUUO, n = 6), PUUO com tadalafil (PUUO T; Cialis, 10 mg/72 h, intragástrica; Lilly, Indianapolis, Indiana, EUA), completa obstrução ureteral unilateral (CUUO, n = 6) e CUUO com tratamento com tadalafil (CUUO T). RESULTADOS: Quinze dias após a UUO, o ureter apresentou alterações nas camadas de urotélio e infiltração significativa de células inflamatórias nos grupos PUUO e CUUO. Em comparação com os grupos sham, PUUO e CUUO, houve um aumento grave da infiltração de células inflamatórias. O epitélio urotelial exibiu degeneração e perda celular devido às células epiteliais inchadas, atróficas e desnudas nos grupos PUUO e CUUO. Nos grupos PUUO T e CUUO T, o urotélio revelou menor degeneração e perda de células epiteliais. Nós mostramos que a expressão da actina do músculo liso-α (α-SMA) e do fator de crescimento transformador-β (TGF-β) foram exibidas como sub-regulação nos grupos PUUO e CUUO. A expressão do TGF-β foi diminuída positivamente correlacionada com a da α-SMA nos grupos de terapia com tadalafil, PUUO T e CUUO T. CONCLUSÃO: O tadalafil do inibidor da fosfodiesterase tipo 5 reduziu as expressões α-SMA e TGF-β nos ureteres obstruídos, medidos por exames bioquímicos. Além disso, o tadalafil diminuiu a degeneração do urotélio devido à diminuição da perda de células epiteliais e da infiltração de células inflamatórias. Nossos resultados mostram que o tadalafil previne ou retarda o início da inflamação do ureter e degeneração urotelial em ratos com UUO.

ABSTRACT Aim: Although prostate cancer (PCa) is the most common cancer type in men, a replaceable risk factor has not yet been established. In our study, we assessed the relationship between the number of sexual partners, age of first sexual experience and age of first masturbation and prostate cancer incidence. Materials and Methods: In Ordu University Department of Urology between January 2013 and September 2016, in PSA elevation and rectal examination, patients with prostate biopsy were evaluated due to nodule palpation in the prostate. At younger ages and at present, their first masturbation ages, first sexual debut ages, and total sexual partner numbers were recorded. The correlation between the obtained data and PCa frequency was evaluated. Results: The study included 146 patients with PCa identified on biopsy and 171 patients with benign biopsy results who answered the questions. 66.7% of the ones whose biopsy results were benign and 40.6% of cancer suspects had only one sexual partner. The median number of sexual partners was 1±4 (1-100) in the benign group and 2±6 (1-500) in the malignant group (p=0.039). There was a negative correlation between age of first sexual debut and number of partners (r: −0,479; p <0.001). Conclusion: In our study, it appears that there may be an association between the number of sexual partners and prostate cancer in the patient group with PSA level above 4ng/mL. Avoidance of sexual promiscuity or participation in protected sex may be beneficial to protect against prostate cancer.

OBJECTIVE: This study investigates ultrasonography as an effective tool for localizing and measuring the depth and size of wooden foreign bodies to perform less invasive and easier surgery without the need for any additional radiological techniques. METHODS: Fifteen patients were operated to remove foreign bodies in the extremities in 2016. The side of the affected extremity, the material, size, and location of the foreign body and time of admission after injury were noted, along with CRP, WBC, and erythrocyte sedimentation rate; length of incision, surgery duration, and complications were evaluated. RESULTS: The mean patient age was 39.66 (range: 6 to 68). Of the total, 8 of the foreign bodies were in the plantar surfaces of the feet, 3 were in the cruris, 2 were in the palm of the hand, and 2 were in the fingers. All patients underwent ultrasound evaluation before surgery. The surgeries lasted less than 10 min in 13 (87%) of the cases and from 10 to 20 min in 2 cases. No complications were observed in any of the patients. CONCLUSION: Delayed extraction of foreign bodies can lead to local infections. Ultrasonography can be a reliable option for diagnosing and localizing radiolucent foreign bodies such as wooden objects. Level of Evidence IV; Case series.
OBJETIVO: Neste estudo, procuramos mostrar que a ultra-sonografia é uma ferramenta eficaz para localizar e medir a profundidade e o tamanho dos corpos estranhos em madeira, a fim de realizar uma cirurgia menos invasiva e mais fácil, sem a necessidade de técnicas radiológicas adicionais. MÉTODOS: 15 pacientes foram submetidos à cirurgia para penetração de corpo estranho nas extremidades em 2016. O lado da extremidade afetada, o material, tamanho e localização do corpo estranho e o tempo de admissão após lesão foram observados. CRP, WBC e taxa de sedimentação de eritrócitos também foram observados. O comprimento da incisão, duração da operação e complicações foram avaliados. RESULTADOS: A idade média do paciente foi de 39,66 (intervalo: 6 a 68). No total, oito de todos os corpos estranhos estavam no lado plantar dos pés, três estavam no crúis, dois estavam na palma da mão e dois estavam nos dedos. Todos os pacientes foram submetidos a avaliação ultra-sonográfica antes da cirurgia. A duração da operação foi inferior a 10 minutos em 13 (87%) dos casos e entre 10 a 20 minutos em dois casos. As complicações não foram observadas em todos os pacientes. CONCLUSÃO: A extração retardada de corpos estranhos pode levar a infeções locais. A ultra-sonografia pode ser uma opção confiável para diagnosticar e localizar corpos estranhos radiolúcidos, como objetos de madeira. Nível de evidência IV; Série de casos.

ABSTRACT Aim: URS is a very commonly used procedure for treatment of ureter stones. Increased hydrostatic pressure in the collecting system linked to fluids used during the procedure may cause harmful effects on the kidney. The aim of this study is to determine whether the URS procedure has a negative effect on the kidney by investigating NGAL, KIM-1, FABP and Cys C levels in urine. Material and Methods: This study included 30 patients undergoing ureterorenoscopy (URS) for ureter stones. Urine samples were collected 5 times; before the URS procedure (control) and at 1, 3, 5 and 12 hours following the procedure. NGAL, KIM-1, FBAP and Cys C levels were measured in urine and compared with the control values. Results: The NGAL levels in urine before the procedure and at 1, 3, 5 and 12 hours after the procedure were 34.59±35.34; 62.72±142.32; 47.15±104.48; 45.23±163.16 and 44.99±60.79ng/mL, respectively (p=0.001). Similarly, the urinary KIM-1, FABP and Cys C levels were found to increase compared to control values; however this increase did not reach statistical significance (p >0.05). Conclusions: After the URS procedure, there were important changes in NGAL, FABP, KIM-1 and Cys C levels. These changes reached statistical significance for NGAL, but did not reach significance for the other parameters. In conclusion, the URS procedure significantly affects the kidney; however, this effect disappears over time.

RESULTS: The NGAL levels in urine before the procedure and at 1, 3, 5 and 12 hours after the procedure were 34.59±35.34; 62.72±142.32; 47.15±104.48; 45.23±163.16 and 44.99±60.79ng/mL, respectively (p=0.001). Similarly, the urinary KIM-1, FABP and Cys C levels were found to increase compared to control values; however this increase did not reach statistical significance (p >0.05). CONCLUSIONS: After the URS procedure, there were important changes in NGAL, FABP, KIM-1 and Cys C levels. These changes reached statistical significance for NGAL, but did not reach significance for the other parameters. In conclusion, the URS procedure significantly affects the kidney; however, this effect disappears over time.

Abstract Background Oxidative and nitrosative stress pathways, along with immune-inflammatory response, might play an important role in the pathogenic mechanisms underlying major depression and bipolar disorder. Objective The aim of the present study is to investigate paraoxonase 1 polymorphisms and its correlations with disease parameters in patients with major depression and bipolar affective disorder. Methods PON1 L55M and Q192R single nucleotide polymorphisms were analyzed in a group consisted of 100 patients with major depression, and 100 patients with bipolar affective disorder and 96 healthy controls. Polymorphisms were analyzed by using polymerase chain reaction. Results Our findings reported no association between Q192R and L55M polymorphisms of PON1 and major depression and bipolar disorder. Additionally, there was no association between the PON1 genotypes and disease variables in both depressed and bipolar patients. Discussion Evaluating the different stages of patients with affective disorders and and investigating the connection between PON1 polymorphisms and treatment outcomes will help us to clarify the relationship between PON1 and mood disorders.
RESUMO
ABSTRACT Introduction Sepsis is an inflammatory reaction to bacteria involving the whole body and is a significant cause of mortality and economic costs. The purpose of this research was to determine whether tadalafil exhibits a preventive effect on sepsis in a septic model induced in rats with cecal ligation and puncture (CLP). Materials and Methods Rats were randomly separated into groups, 10 rats in each: (i) a sham (control) group, (ii) an untreated sepsis group, (iii) a sepsis group treated with 5mg/kg tadalafil and (iv) a sepsis group treated with 10mg/kg tadalafil. A polymicrobial sepsis model was induced in rats using CLP. Rats were sacrificed after 16h, and blood and kidney tissues were collected for biochemical and histopathological study. Results Levels of the inflammatory parameter IL-6 decreased significantly in the sepsis groups receiving tadalafil in comparison with the untreated sepsis group (p<0.05). In terms of histopathology, inflammation scores investigated in kidney tissues decreased significantly in the sepsis groups receiving tadalafil compared to the untreated sepsis group (p<0.05). In addition, levels of creatinine and cystatin C measured in septic rats receiving tadalafil were lower by a clear degree than in septic rats (p<0.05). Conclusion In this study, tadalafil exhibited a preventive effect for sepsis-related damage by suppressing inflammation in serum and kidney tissue of septic rats in a polymicrobial sepsis model induced with CLP.

We investigated whether the insertion/deletion (I/D) polymorphism in the angiotensin-converting enzyme (ACE) gene and serum ACE levels are associated with traditional risk factors of coronary artery disease (CAD). We enrolled 250 individuals without CAD and 750 individuals suffering from CAD who were angiographically diagnosed. Biochemical risk factors, the ACE (I/D) gene polymorphism, and ACE serum levels were compared. ACE genotypes were determined using real-time polymerase chain reaction. ACE serum levels were determined using an enzyme-linked immunosorbent assay. Lipid parameters were determined spectrophotometrically using an autoanalyzer. Compared to the control group, the CAD group showed significantly higher serum ACE levels (P < 0.001). The highest ACE levels were found in those with the DD genotype. Other genotypes also presented statistically significant differences. We observed a significant difference between the control and coronary patient groups regarding the levels of total cholesterol, triglyceride, high-density lipoprotein-cholesterol, and low-density lipoprotein-cholesterol (P < 0.05). ACE (I/D) genotypes and serum ACE levels may be associated with risk factors and the development of CAD.
