Impact of VieScope® on first-attempt success during simulated COVID-19 patients intubation: A randomized cross-over simulation trial.

BACKGROUND: The purpose of our study was to determine the efficacy of intubation with VieScope® and Macintosh laryngoscope in different scenarios of simulated COVID-19 patients by paramedics wearing personal protective equipment (PPE) for aerosol gener-ating procedures (AGPs). METHODS: Study was designed as a prospective, observational, randomized, crossover simulation trial. 37 paramedics took part in the study. They performed endotracheal intubation (ETI) of a person suspected of COVID-19. Intubation was performed using VieS-cope® and Macintosh laryngoscopes in two research scenarios: Scenario A - normal airway and Scenario B - difficult airway. Both the order of participants and the methods of intubation were random. RESULTS: In Scenario A, time to intubation using VieScope® and Macintosh laryngoscope amounted to 35.3 (IQR; 32-40) seconds and 35.8 (IQR: 30-40)s, respectively. Nearly all participants performed ETI successfully both with VieScope® and Macintosh laryngo-scope (100% vs. 94.6%). In scenario B, intubation with the VieScope®, compared to the Macintosh laryngoscope, was associated with a shorter intubation time (p<0.001), a higher success rate of the first intubation attempt (p<0.001), a better visualization degree glottis (p=0.012) and ease of intubation (p<0.001). CONCLUSION: Our analysis suggests that the use of a VieScope® compared to Macintosh laryngoscope in difficult airway intuba-tion performed by paramedics wearing PPE-AGP is associated with shorter intubation times, greater intubation efficiency as well as better visualization of the glottis. Additional clinical trials are necessary to confirm the obtained results.

The Impact of Lung Ultrasound on Coronavirus Disease 2019 Pneumonia Suspected Patients Admitted to Emergency Departments.

OBJECTIVE: The aim of this study was to identify the sensitivity and specificity of lung ultrasound (LUS) and show its place in diagnosing patients with known coronavirus disease 2019 (COVID-19) pneumonia, according to chest computed tomography and the COVID-19 reporting and data system (CO-RADS). METHODS: Nineteen patients who admitted to a single university hospital emergency department between March 5, 2020, and April 27, 2020, describing dyspnea were included in the study and underwent LUS by a single emergency specialist. The patient population was divided into 2 groups, COVID-19 positive and negative, and the sensitivity and specificity of LUS according to chest computed tomography were calculated for COVID-19 pneumonia diagnosis. In the subgroup analysis, the patient group was divided into real-time reverse transcription-polymerase chain reaction positive (n = 7) and negative (n = 12), and sensitivity and specificity were calculated according to the CO-RADS. RESULTS: According to the CO-RADS, significant differences were detected between the LUS positive and negative groups in terms of COVID-19 pneumonia presence. Only 1 patient was evaluated as CO-RADS 2 in the LUS positive group, and 2 patients were evaluated as CO-RADS 4 in the LUS negative group (P = 0.04). The sensitivity of LUS according to the CO-RADS for COVID-19 pneumonia diagnosis was measured to be 77.78% (95% confidence interval [CI], 39.9%-97.1%), specificity was 90% (95% CI, 55.5%-99.75%), positive predictive value was 87.5% (95% CI, 51.35%-97.8%), and accuracy was 84.21% (95% CI, 60.4%-96.62%; P = 0.004). CONCLUSIONS: In conclusion, LUS is easily used in the diagnosis of COVID-19 pneumonia because it has bedside application and is fast, easy to apply, reproducible, radiation free, safe for pregnant women, and cheap.

Occupational burnout, job satisfaction and anxiety among emergency medicine doctors in Turkey.

OBJECTIVE: The objective of the study was to investigate possible differences in the levels of anxiety, burnout and job satisfaction among emergency medicine doctors based on their age, gender, employment duration, job title and institution. METHODS: General practitioners, residents, specialists and faculty members working in emergency departments (ED) in Turkey were invited to participate in this questionnaire-based study through an e-mail link between September 2018 and January 2019. A total of 141 doctors from different cities of Turkey who completely filled the questionnaire with their own will were recruited for the study. The Maslach Burnout Inventory(MBI) was used to measure occupational burnout levels, the State-Trait Anxiety Inventory(STAI) to measure anxiety levels and the Short Form Minnesota Satisfaction Questionnaire(SFMSQ) to measure job satisfaction levels of doctors working in EDs. In assessing MBI; Emotional Exhaustion score(EE) is considered low for 0-11 points, moderate for 12-17 points and high >17 points; Depersonalization score is considered low for 0-5 points, moderate for 6-9 points and high ≥ 10 points; , Feeling of low personal accomplishment(PA) is considered low for 0-21 points, moderate for 22- 25 points and high ≥ 26 points. In Assessing STAI; 20- 49 points were considered low/ moderate anxiety and 50- 80 points considered high/ very high anxiety. In assessing SFMSQ neutral job satisfaction point was reported 3; so individuals are considered extremely dissatisfied/ not satisfied (low) if job satisfaction point <3 and very/ extremely satisfied (high) if job satisfaction point >3. RESULTS: The mean age of the study group was 33.3 (±7.3) and mean employment duration was 8.37 (±6.89). In the overall study population, the emotional exhaustion(EE) was high while depersonalization(DP) and reduction of personal accomplishment(PA) were detected at medium level in the evaluation of MBI subscales. In evaluating overall study population for STAI, state and trait anxiety scores both showed the presence of mild to moderate anxiety. The overall study population evaluation results for SFMSQ were, high levels of general and intrinsic job satisfaction and low levels of extrinsic job satisfaction was measured. Younger the age and shorter the duration of employment is found to be associated with a significant increase in EE and DP and a significant decrease in PA. CONCLUSION: In this study, scale results showed that doctors working in EDs had high levels of occupational burnout and anxiety, while job satisfaction levels were low. In addition, a significant relationship was found between the decrease in "age and employment duration" and the increase in "depersonalization".

Comparison of intravascular access methods applied by nurses wearing personal protective equipment in simulated COVID-19 resuscitation: A randomized crossover simulation trial.

BACKGROUND: Prehospital emergency care of children is challenging. In the era of the COVID-19 pandemic, when medical personnel should use personal protective equipment against aerosol-generating procedures, the efficiency of medical procedures may decrease. The study objective was to evaluate the effectiveness of different intravascular access methods applied by nurses wearing biosafety Level-2 suits in simulated paediatric COVID-19 resuscitation. METHODS: A prospective, randomized, crossover, single-blinded simulation trial was performed. Nursing staff attending Advanced Cardiovascular Life Support courses accredited by the American Heart Association participated in the study. A total of 65 nurses were recruited and randomly assigned to different study groups. They received standard training on intravascular access methods employing distinct devices. The participants wore biosafety Level-2 suits and performed vascular access with the following intraosseous devices: NIO-P, EZ-IO, and Jamshidi needle; intravenous (IV) access was used as a reference method. Both the order of participants and the access methods were random. Each participant performed intravascular access with each of the four methods tested. The effectiveness of the first attempt to obtain intravascular access and the following time parameters were analysed: the time between grasping the intravascular device out of the original packing until infusion line connection. The ease of the procedure was measured with a visual analogue scale (1 - easy; 10 - difficult). RESULTS: The first attempt success rate of intravascular access by using NIO-P and EZ-IO equalled 100% and was statistically significantly higher than that with the Jamshidi needle (80.0%; p = 0.02) and with the IV method (69.2%; p = 0.005). The time required to connect the infusion line varied and amounted to 33 ± 4 s for NIO-P compared to 37 ± 6.7 s for EZ-IO (p<0.001), 43 ± 7 s for Jamshidi (p<0.001), and 98.5 ± 10 s for IV access (p<0.001). The procedure was easiest in the case of NIO-P and EZ-IO (2 ± 1 points; p=1.0) compared with Jamshidi (5 ± 3 points; p<0.001) and IV access (7 ± 2 points; p<0.001). CONCLUSION: The study provides evidence that nurses wearing biosafety Level-2 suits were able to obtain intraosseous access faster and more effectively as compared with IV access during simulated COVID-19 paediatric resuscitation. The most effective method of intravascular access was the NIO-P intraosseous device. Further clinical trials are necessary to confirm the results.

Is There a Difference Between the Readabilities of Informed Consent Forms Used for Elective and Emergency Procedures in Turkey?

BACKGROUND: Informed consent is an important aspect of ethical medical practice. In legal terms, making an intervention without informed consent may mean negligence or malpractice and may lead to legal action, maltreatment, and even attack against the doctor. This study aims to evaluate the readability of informed consent forms (ICFs) used for elective (urology and general surgery) and emergency procedures (emergency medicine and intensive care) by comparing through readability formulas. METHOD: Elective and emergency ICFs were accessed through the web sites of national health care associations. A total of 387 consent forms were evaluated and the same forms were included only once. A total of 35 consent forms were evaluated for emergency procedures, while a total of 55 consent forms were evaluated for elective procedures. Atesman and Bezirci-Yilmaz formulas defined for determining the readability level of Turkish texts and Gunning fog and Flesch Kincaid formulas measuring the general readability level were used for calculating the readability level of consent forms. RESULTS: Even though elective ICFs are more readable compared to those of emergency procedures according to Bezirci-Yilmaz formulas, this was statistically insignificant ([Formula: see text]). The readability of elective consent forms was found to be at a significantly more difficult level to read compared to Atesman, Gunning fog, and Flesch Kincaid formulas ([Formula: see text], [Formula: see text], [Formula: see text], respectively). CONCLUSION: Even though the procedure is emergency or elective, a difficult readability level may cause problems for the doctor in legal phases. Readable and understandable consent forms should be available to be able to explain morbidity and mortality and improve prognosis. Education level of our country should also be considered while preparing these consent forms.

Is there a Difference in Platelet-Rich Plasma Application Method and Frequency to Protect Against Urethral Stricture?

PURPOSE: To determine the efficacy of instillation frequency and submucosal injection of platelet-rich plasma (PRP) after urethral trauma to prevent urethral inflammation and spongiofibrosis. MATERIALS AND METHODS: Sixty-five rats were used in the study; 50 rats were randomized into 5 groups with 10 rats in each group and 15 rats were allocated for PRP preparation. The urethras of all rats were traumatized with a pediatric urethrotome knife at 6 and 12 o'clock positions, except in the sham group. Group 1 was the sham group and had only urethral catheterization daily for 15 days, Group 2 was given 0.9% saline (physiologic saline [(UI+PS]) once a day after urethral injury (UI+ PS), Group 3 was injected with PRP submucosally after urethral injury, Group 4 was given PRP once a day as intraurethral instillation using a 22 Ga catheter sheath with urethral injury, and Group 5 was given PRP twice a day as intraurethral instillation using a 22 Ga catheter sheath with urethral injury. Each administration of PRP was administered as 300 million platelets/150 microliters. On day 15, the penises of the rats were degloved to perform penectomy. Histopathologic evaluation was made for spongiofibrosis, inflammation, and congestion in vascular structures. RESULTS: When the sham group, UI+PS, UI+PRPx1, UI+PRPx2 and UI+PRPs groups are compared in total, there were significant differences identified for parameters other than edema. When the UI+PS, UI+PRPx1, UI+PRPx2 and UI+PRPs groups are compared, the UI+PS group was observed to have significantly more inflammation (mucosal inf. 2.42 ± 0.53) and spongiofibrosis (2.42 ± 0.53). All the PRP groups were identified to have significantly less mucosal inflammation (UI+PRPs 1 ± 0, UI + PRPx1; 1.4 ± 0.51, PRPx2; 1.33 ± 0.5) and spongiofibrosis (UI+PRPs; 1.57 ± 0.53, PRPx1; 1.2 ± 0.42, PRPx2; 1.55 ± 0.52). The group with the lowest spongiofibrosis was the PRPx1 group. CONCLUSION: This study showed that PRP significantly reduced mucosal inflammation and spongiofibrosis, independent of the administration route, when applied to the urethra after urethral trauma.

Do variations in labial anatomy have an effect on recurrent urinary tract infection?

INTRODUCTION AND HYPOTHESIS: Variations in labial anatomy may constitute a risk factor for vaginal pH increase and recurrent UTIs. Our objective in this study was to show the effects of variations in labial anatomy on vaginal pH and recurrent UTI. METHODS: A total of 331 non-menopausal and sexually active patients between the ages of 18 and 50, meeting recurrent urinary infection criteria and not meeting exclusion criteria were included in the study in group 1, the infection group, and 440 patients without recurrent UTI were included in group 2, the control group. Vaginal pH values of the participants were measured. Labia minora were classified as labial anatomy based on the Banwell classification. Predisposing factors and demographic data were also questioned, measured, recorded, and compared. RESULTS: A significant difference was detected in labial anatomy between groups 1 and 2 based on the Banwell classification. Banwell type 3 in group 1 (76%) and Banwell type 2 in group 2 (55%) were observed to be significantly higher. There was a significant difference in right and left vertical and horizontal dimensions of the labia minora between the two groups. It was also observed that the vaginal pH was significantly more alkaline in group 1 compared with group 2 (6.11 vs 4.48). CONCLUSION: Although there are many causes of recurrent urinary tract infections, this study showed that vaginal pH imbalance and labia minora anatomy in the lower third prominence based on the Banwell classification (type 3) were among the most important causes. Thus, we think that the vaginal anatomy should be evaluated in recurrent UTI patients.

Histopathologic Evaluation of the Effects of Intraurethral Platelet Rich Plasma in Urethral Trauma Experimentally Induced in Rat Model.

OBJECTIVE: To determine the efficacy of platelet rich plasma applied early initialization after urethral trauma for preventing inflammation and spongiofibrosis. MATERIALS AND METHODS: Twenty-three rats were randomized and divided into 3 groups, with 10 rats in 2 groups. Only sham group had 3 rats. The urethras of all rats were traumatized with a pediatric urethrotome knife at 6- and 12-o'clock. For 15 days, group I was given platelet rich plasma (PRP) once a day without urethral injury (sham group), group II (n = 10) was not given any medical treatment only urethral injury group (UI-PRP), group III (n = 10) was given PRP once a day intraurethrally as instillation using a 22 ga catheter sheath with urethral injury (UI+PRP). On day 15, the penises of the rats were degloved to perform penectomy. RESULTS: A significant difference was detected in all parameters when the sham, UI-PRP, UI+PRP groups were compared (respectively, P = .001, / <.001, / .008 / .007) and a significant difference was observed among mucosal inflammation, fibrosis, and edema parameters when UI-PRP and UI+PRP groups were compared. (Respectively; P <.001, / <.001 / .006). CONCLUSION: In this study, it was shown that intraurethral PRP applied after urethral trauma significantly decreased mucosal inflammation, spongiofibrosis, and edema. Depending on the results we acquired in this study, we think that PRP may be a promising option in urethral stricture treatment.

Evaluating Stable Chronic Obstructive Pulmonary Disease by Ultrasound.

BACKGROUND AND AIM: The purpose of the study was to evaluate the relationship between COPD severity and the diaphragmatic function measured by point-of-care US in patients with stable COPD. METHOD: A total of 61 patients with COPD and 40 healthy subjects who had been admitted to Ufuk University Hospital between December 2018 and May 2019 were enrolled. Point-of-care US was performed, and lung silhouette and anterior, right, and left hemidiaphragm method in M-mode were used to evaluate the diaphragm. RESULTS: The point-of-care US measurements, lung silhouette method right (Lung Sil R), lung silhouette method left (Lung Sil L), right hemidiaphragm US method in B-mode (Ant B-Mode R), and right hemidiaphragm US method in M-mode (Ant M-Mode R), were significantly different among groups (P < 0.001 for each). FEV1 was strongly correlated with Lung Sil R, Lung Sil L, Ant B-Mode R, and Ant M-Mode R (r = 0.963, P < 0.001; r = 0.956, P < 0.001; r = 0.953, P < 0.001; and r = 0.917, and P < 0.001, respectively). Negative correlations were detected between the number of exacerbations per year and Lung Sil R and the number of exacerbations per year and Ant M-Mode R (r = -0.599, P < 0.001 and r = -0.587, and P < 0.001, respectively). CONCLUSION: In this study, FEV1 and annual number of exacerbations turned out to be strongly correlated US findings. The use of US in COPD patients could help to support clinical decision, but further clinical studies are necessary to confirm those findings.

New treatment modalities with vaccine therapy in renal cell carcinoma.

The aim of implementing vaccine therapy is to activate immune response against malignant cells by overcoming the tolerance triggered by the tumor. These treatments are effective using the immune response against cancer. Not every type of cancer is suitable for vaccine therapies. For a vaccine therapy to be implemented, cancer should be immunogenic and contain tissue-specific proteins, should have a slow progression, and treatments should be feasible. For that reason, studies regarding urological cancers are mostly focused on the kidneys and the prostate. Vaccine therapies used in renal cell carcinoma (RCC) can be categorized under the following titles: autologous tumor cells, dendritic cells, genetically modified tumor cells, and protein/peptide. Although there are old studies on the implementation of vaccine therapies in RCC, researches have only been intensified recently. In addition to their effective potential for lengthening general survival, decreasing tumor burden and cancer development in long term, vaccine treatments are especially effective in metastatic RCC patients. We think that vaccine treatments would be applied more in near future since RCC are immunogenic. In this compilation, we will discuss vaccine therapies used in RCC, which urologists are not so familiar with, in the light of the up-to-date literature.

Etiological factors and management in priapism patients and attitude of emergency physicians.

OBJECTIVE: To present the underlying etiological factors in patients referring with priapism, sharing how they are managed according to etiology and priapism type together with our experiences, creating awareness so that urologists and emergency physicians may play a more active role together in priapism management. MATERIALS AND METHODS: Patients referring to emergency service with priapism were examined. Penile Doppler ultrasonography (PDU) and/or corporeal aspiration and blood gas analysis were made in order to determine priapism type after anamnesis and physical examination. The most appropriate treatment option was chosen and applied on the patients considering priapism type, underlying etiological factors and priapism time. Presence of a statistical difference between etiological factors causing priapism, priapism type and applied treatment methods was calculated using Chi square (χ2) test. RESULTS: A total of 51 patients referring to emergency service with priapism attacks for 53 times were included in the evaluation. When compared to other etiological factors, number of priapism cases developing secondary to papaverine after PDU was found statistically significantly high (p < 0.001). Ischemic priapism ratio was detected statistically higher compared to other groups (p < 0.001). Aspiration and/or irrigation treatment were the most common method used for treatment at a statistically significant level (p < 0.001). All patients (100%) were hospitalized in urology service without applying any treatment in emergency service and had treatment and intervention under the control of the urologist. CONCLUSIONS: Application of non-invasive treatments in suitable priapism patients would protect patients from invasive painful interventions. We believe that emergency physicians should be more effective in priapism phase management and at least noninvasive treatment phase.

Ischemic priapism: Can eosinophil count and platelet functions be positive predictive factors in etiopathogenesis.

INTRODUCTION: We evaluated the relation between ischemic priapism (IP) and blood count parameters in IP patients. We especially wanted to examine the contribution of eosinophil count (EC), platelet count (PC), and mean platelet volume (MPV) values, which are suspected predictive parameters for vascular endothelium damage and venoocclusive pathogenesis and etiopathogenesis, particularly in IP. METHODS: A total of 40 IP patients fulfilled the study criteria. Forty healthy volunteers in a similar age group were included as the control group. Complete blood count values were compared between the two groups. Intergroup comparisons were performed using the Mann-Whitney U test, and the chi-square test was used to assess the relationship between categorical variables in the patient groups. The area under the curve was calculated by receiver operating characteristic (ROC) regression analyses. Epidemiological diagnosis percentages were calculated by finding cutoff values. RESULTS: The IP group's high MPV, PC, and EC values compared to those of the control group were detected to be statistically significant (p<0.001, p=0,03, p=0.001, respectively). No statistically significant difference was observed between the two groups for other blood count parameters. Statistically significant values for IP were measured as MPV: positive predictive value: 84%; EC: positive predictive value: 71.4%; and PC: positive predictive value: 61.4%. CONCLUSIONS: High MPV, PC, and EC values are significant positive predictive factors in IP etiopathogenesis. No proof was detected for other blood count parameters playing an active role in IP etiopathogenesis.

Is there a relationship between penile vasculogenic erectile dysfunction, platelet functions and eosinophil count? / Existe una relación entre la disfunción eréctil vasculogénica del pene, las funciones de plaquetas y el conteo de eosinófilos?

Purpose. Blood count parameters of patients referring with penile vasculogenic erectile dysfunction (ED) were examined in this study. It was investigated whether eosinophil count (EC), platelet count (PC) and mean platelet volume (MPV), values among the suspected predictive parameters which may affect vascular functions, have a contribution on ED pathology or not. Materials and methods. Patients referring erectile dysfunction complaint were evaluated. Depending on the medical story, ED degree was determined by measuring International Index of Erectile Function (IIEF). Values such as hormones, complete blood count and other laboratory markers were examined. Penile doppler ultrasonography (PDU) was performed in patients suspected to have vasculogenic ED. According to PDU result, patients with vascular deficiency were included in the penile vasculogenic ED group and patients with normal results were included in the control group. 49 patients participated in the study from the penile vasculogenic ED group and 30 patients from the control group. Intergroup comparisons were performed using the Mann-Whitney U test and the chi-square (χ2) test was used to assess the relationship between categorical variables within the patient groups. Results. Low IIEF score in vasculogenic ED group compared to the control group and high EC, MPV and PC values were detected to be statistically significant (p<0.001, p=0.026, p=0.009, p=0.029, respectively). No statistically significant difference was observed among the two groups when age, white blood cells, red blood cells or hemoglobin values are considered (p=0.332, p=0.235, p=0.127, p=0.696, respectively). Conclusion. High MPV value and platelet count showing the platelet functions and high eosinophil count are important factors which may play a role in penile vasculogenic ED etiopathogenesis (AU)

Propósito. Los parámetros de conteo de sangre de los pacientes referidos con disfunción eréctil (DE) vasculogénica del pene fueron examinados en este estudio. Se investigó si los valores de conteo de eosinófilos (CE), el conteo de plaquetas (CP) y el volumen plaquetario medio (VPM), entre los parámetros predictivos sospechados de afectar las funciones vasculares, contribuyen a la patología de DE o no. Materiales y métodos. Se evaluó a los pacientes referidos con quejas de DE. Dependiendo de su historial médico, el grado de DE fue determinado midiendo el índice internacional de función eréctil (IIFE). Se examinaron los valores de hormonas, el conteo total de sangre y otros valores de laboratorio. Se utilizó la ultrasonografía Doppler peneana (UDP) en pacientes en los que se sospechaba DE vasculogénica. Según el resultado de la UDP, los pacientes con deficiencia vascular fueron incluidos en el grupo de DE vasculogénica del pene y los pacientes con resultados normales fueron incluidos en el grupo de control. En el estudio participaron 49 pacientes en el grupo de DE vasculogénica del pene y 30 pacientes en el grupo de control. Las comparaciones intergrupales fueron realizadas utilizando el test U de Mann-Whitney y el test de la chi cuadrado (χ2) para analizar la relación entre los variable categóricos en los grupos de pacientes. Resultados. Resultados bajos de IIFE en el grupo de DE vasculogénica comparados con el grupo de control y resultados altos de CE, VPM y PC fueron detectados como estadísticamente significativos (p<0,001, p=0,026, p=0,009 y p=0,029, respectivamente). No se observó ninguna diferencia significativa estadísticamente entre los 2 grupos cuando se consideraron los valores de edad, glóbulos blancos, glóbulos rojos y hemoglobina (p=0,332, p=0,235, p=0,127 y p=0,696, respectivamente). Conclusión. Unos valores altos de VPM, un conteo de plaquetas que muestra las funciones de plaquetas y un conteo alto de eosinófilos son factores importantes que pueden desempeñar un papel en la etiopatogenia de la DE vasculogénica del pene (AU)

Can Eosinophil Count, Platelet Count, and Mean Platelet Volume Be a Positive Predictive Factor in Penile Arteriogenic Erectile Dysfunction Etiopathogenesis?

Blood count parameters of patients referring with erectile dysfunction (ED) were examined in this study and it was investigated whether eosinophil count (EC), platelet count (PC), and mean platelet volume values among the suspected predictive parameters which may play a role in especially penile arteriogenic ED etiopathogenesis had a contribution on pathogenesis. Patients referring with ED complaint were evaluated. Depending on the medical story, ED degree was determined by measuring International Index of Erectile Function. Penile Doppler ultrasonography was taken in patients suspected to have vasculogenic ED. According to penile Doppler ultrasonography result, patients with arterial deficiency were included in the penile arteriogenic ED group and the patients with normal results were included in the nonvasculogenic ED group. A total of 36 patients participated in the study from the penile arteriogenic ED group and 32 patients from the nonvasculogenic ED group. Compared with the nonvasculogenic ED group, the penile arteriogenic ED group's low International Index of Erectile Function score, high EC, mean platelet volume and PC values were detected to be statistically significant ( p < .001, p = .021, p = .018, p = .034, respectively). No statistically significant difference was observed among the two groups when age, white blood cells, red blood cells, and hemoglobin values were considered. Pansystolic volume velocities were detected as statistically significantly low compared with the nonvasculogenic ED group in the measurements made in 5th, 10th, 15th, and 20th minutes on the right and left sides in the penile arteriogenic ED group. High MPV value and PC is a significant predictive factor for penile arteriogenic ED and vasculogenic ED and high EC is specifically predictive of arteriogenic ED.

What should be done to minimize pain without any sexual function deterioration in transrectal prostate biopsy?

INTRODUCTION: The aim of this study was to find an ideal method for the application of a transrectal ultrasound-guided prostate biopsy (TRUS-Bx) without deteriorating patient comfort. MATERIAL AND METHODS: TRUS-Bx was applied in a total of 93 patients. Taking the application method into consideration, these patients were divided into three groups, each consisting of 31 patients. Methods applied for pain control in the different groups were compared (groups 1, 2 and 3). Age, prostate specific antigen (PSA), prostate volume, cancer detection rate, re-biopsy consent ratio, complication rates, visual analog scale (VAS), and International Index of Erectile Function (IIEF-5) scores were compared among the groups. RESULTS: Age, PSA, prostate volume, cancer detection rate, and fever complication rate were not statistically different between the three groups. However, a statistically significant difference was detected among the groups for the VAS measured during and after TRUS-Bx, re-biopsy consent ratio, and hematuria (p <0.001, p <0.001, p <0.001, and p = 0.027, respectively). There was no detected difference in pre-operation IIEF-5 scores, but the difference in IIEF-5 scores in the first month after the operation was significant (p = 0.116, p = 0.024, respectively). CONCLUSIONS: Anal dilatation after the application of intrarectal topical anesthetic to provide anesthesia during TRUS-Bx and giving lidocaine hydrochloride with epinephrine for periprostatic nerve blockage (PNB) is a successful and effective method to maintain patient comfort, especially as it relates to pain control and sexual function. Anal dilatation seems to minimize any pain that may occur due to probe transition, and adding epinephrine as a vasopressor to the anesthetic agent chosen during the operation will be rather helpful for hemostasis control and pain that results from the needle.
