Pain during sexual activity and ejaculation following hernia repair: A retrospective comparison of transabdominal preperitoneal versus Lichtenstein repair

Pain during sexual activity and ejaculation are the unspoken long-term complications of groin hernia repair. Laparoscopic surgical techniques are associated with decreased post-operative pain and earlier return to daily activities, but its effect on these complications is unclear. This study aims to investigate the effect of transabdominal preperitoneal repair (TAPP) on de-novo pain during sexual intercourse and ejaculation and to compare with open repair. For this reason, two groups were determined according to the surgical technique: the Lichtenstein repair and the TAPP groups and a questionnaire was sent to the patients a minimum of 6 months following the surgery. A total of 317 patients included, as 115 in TAPP and 202 in Lichtenstein repair group. No significant difference was observed concerning pre-operative pain during sexual activity and ejaculation in both groups (p = .75, p = .56). Following the surgery, the number of patients experiencing painful sexual activity was significantly higher in the Lichtenstein repair group compared to the TAPP group (19.3% vs. 11.3%, respectively, p = .03). The post-operative painful ejaculation rate was also significantly lower for the TAPP group (p = .04). The lower rates of post-operative dysejaculation and pain during sexual activity can be achieved with the advantage of laparoscopic surgery.     

Is ‘Omega Sign’ anatomical endoscopic enucleation of the prostate technique reproducible?

We aimed to evaluate the learning curve of the surgically standardised ‘Omega Sign’ anatomical endoscopic enucleation (AEEP) of the prostate surgery technique for junior surgeons. This study is a retrospective comparison of cases that underwent AEEP by a mentor surgeon and three junior surgeons who have completed their learning curve. A video-based laser enucleation of the prostate assessment tool (LEAT) composed of 8 steps of the technique was used to assess a senior surgeon and junior surgeons’ surgical compatibility and consistency. The surgeon who defined Omega Sign technique was determined as group 1, and cases by three junior surgeons were identified as group 2. The end points were to assess the reproducibility and repeatability and operative post-operative outcomes of the technique. 55 patients’ videos were rated by five experienced endourologists. There was no significant difference in LEAT scores between the groups among all steps. The most symmetry was found in the 1st and 3rd steps. Inter-rater consistency was also high for each step, with no statistically significant difference between the evaluators. The standardised anatomical ‘Omega Sign’ technique is reproducible for the junior surgeons. The operative steps can be performed with high consistency, and the functional and perioperative outcomes are comparable with the senior surgeon.     

Comparison of the efficacy of low-intensity shock wave therapy and its combination with platelet-rich plasma in patients with erectile dysfunction

We aimed to compare the efficacy of low-intensity shock wave therapy (Li-SWT) alone and its combination with platelet-rich plasma (PRP) in the treatment of patients with erectile dysfunction (ED). Between January 2015 and October 2020, patients who did not benefit from the use of phosphodiesterase type 5 inhibitors (PDE5i; 5 mg/day) for at least 3 months and underwent Li-SWT or Li-SWT with PRP were evaluated retrospectively. There were 93 patients who were subjected to Li-SWT only (Group 1) and 91 patients subjected to Li-SWT with PRP (Group 2). Analysis of the International Index of Erectile Function-Erectile Function Area (IIEF-EF) scores showed a significant increase in both the groups post-treatment (Group 1: from 14.33 ± 4.39 to 23.8 ± 4.37, p = .001; Group 2: from 17.82 ± 3.44 to 26.3 ± 2.55, p = .001). When the increase in the IIEF-EF scores was compared pre- and post-treatment between the groups with respect to the ED grades, there was no statistically significant difference between them. Furthermore, while the intravaginal ejaculatory latency time (IELT) in successfully treated patients of Group 1 remained the same, Group 2 presented 1.5–3.5 times (mean, 2.4) prolongation. Their mean IELT score showed an increase from 2.2 (0.8–3.5) min to 5.3 (2.8–10.5) min. Our study shows that combination treatment of Li-SWT with PRP injections is not only safe for patients with ED, but also effective and safe in prolonging the IELT.     

Mean Platelet Volume is Associated with Diabetic Macular Edema in Patients with Type-2 Diabetes Mellitus

Aim: To evaluate the effect of the platelet indices on the stage of diabetic retinopathy (DR) and diabetic macular edema (DME). Methods: In this retrospective study, the mean platelet valume (MPV), Plateletcrit (PCT), platelet (PLT), and platelet distribution width (PDW) of 199 diabetic patients and 76 healthy subjects were enrolled. The participants were divided into four groups. The first group was healthy control; the second group consisted of diabetic patients without DR; the third group was nonproliferative DR (NPDR); and the fourth group was proliferative DR (PDR). Results: Significant differences were found only in MPV and PCT values between patients with diabetes and healthy participants (8.6±0.96 fL vs 8.32±0.9 fL, P=0.011, 0.216± 0.58 vs 0.202±0.52, P=0.038). Comparing the groups, a statistically significant difference in MPV values was found between groups 4 and 1 (8.91±.7 fL vs 8.32±0.9 fL P=0.001) and between groups 4 and 3 (8.91±.7 fL vs 8.42±0.9 fL P=0.014). The MPV values of patients with DME were significantly higher than those of diabetic patients without DME (8.87±0.80 fL vs 8.45±0.97 fL). Conclusion: High MPV values may be an important risk factor for the development of PDR and DME in patients with diabetic retinopathy.     

The Role of Serum Resolvin D1 Levels in Determining the Presence and Prognosis of ST-Segment Elevation Myocardial Infarction

BackgroundResolvin D1 (RvD1) can play a determining role in inflammatory cell migration and reduce the expression of inflammatory cytokines to enhance cardioprotection. The aim of this study was to compare serum RvD1 levels in patients with ST-segment elevation myocardial infarction (STEMI) and individuals with normal coronary arteries (NCAs) and to evaluate the association between serum RvD1 levels and prognostic markers of STEMI.Methods140 subjects (88 patients diagnosed with the indication of STEMI and 52 healthy individuals with NCA) were studied.ResultsRegression analysis revealed that RvD1 levels were independently associated with STEMI. While RvD1 levels were negatively correlated with high-sensitivity C-reactive protein, pro-brain natriuretic peptide, peak troponin, and Thrombolysis in Myocardial Infarction thrombus grade, they were positively correlated with left ventricular ejection fraction. An RvD1 cut-off value of 5.07 (ng/mL) was effective in predicting STEMI with a sensitivity of 79.5% and specificity of 96.2%.ConclusionSerum RvD1 levels were found to be lower in the group with STEMI compared to the control group. Levels of RvD1 at admission were associated with poor prognostic markers of STEMI.     

Influence of Low- to Medium-Kaolinite Clay on the Durability of Limestone Calcined Clay Cement (LC3) Concrete

The kaolinite content is principally responsible for the durability performance of Limestone Calcined Clay Cement (LC3), which calls into question its global applicability. The clay supply has a significant impact on the LC3 system’s reduced carbon footprint advantage. The influence of kaolinite concentration from two separate clays (collected in East South-East Europe) on the durability performance of concrete was investigated in this study. The low-kaolinitic clay had 18% kaolinite, while the medium-kaolinitic clay contained around 41% kaolinite. The compressive strength, chloride intrusion, electrical conductivity, surface resistivity, and sorptivity index were measured on concrete after 28 days. Furthermore, the pore structure development of these mixtures was investigated in relation to the kaolinite content of the mixtures. The reactivity test was performed on clays to measure their reactivity levels within the cementitious system. The results show that kaolinite content has a moderate effect on compressive strength, but it has a considerable effect on other durability indices. When compared to the Portland cement mixture, the chloride migration and diffusion coefficients were reduced by 50% and 36%, respectively, in the combination with a medium kaolinite content (more than 40%). The low-kaolinitic clay, on the other hand, achieved 60% of the chloride penetration resistance of the medium-kaolinitic clay. Furthermore, low-kaolinitic clay has been demonstrated to be suitable for low-carbon concrete in moderate exposure conditions.     

Anterior epitympanic recess volume and Cog process length in temporal bones with Körner's septum: A radio- anatomical investigation

ObjectiveKörner's septum is a dense bony lamina dividing the mastoid cavity into superficial squamous and deeper petrosal portions at the level of antrum. In this study, we aimed at investigating the association of the Körner's septum with the length of the Cog process and the volume of anterior epitympanic recess (AER), using the 3-dimensional reconstruction models based on high resolution computed tomography sections of the temporal bone.MethodsUsing OsiriX software for MacOS (version 3.8.1, Pixmeo), we measured the volumes from three- dimensional models of anterior epitympanic recess. Anterior epitympanic recess volumes and Cog process lengths of the temporal bones with and without Körner's septum were compared.ResultsCog process length was significantly higher, and AER volume was significantly lower in patients with Körner's septum compared to the patients without. (p < 0.001). Additionally, Cog process length was significantly (p = 0.008), negatively, but weakly (rho= ?0.24) correlated with AER volume.ConclusionTemporal bones with Körner's septum had a longer Cog process and a smaller AER.     

Remifentanil/midazolam versus tramadol/midazolam use for colonoscopy

One of the most commonly performed outpatient procedure is colonoscopy. The pain and anxiety is frequently associated with colonoscopy. The aim of this study was to compare the effectiveness of remifentanil/midazolam, and tramadol/midazolam for iv sedation and analgesia during colonoscopy. Twentysix patients (age range 18-65 years) scheduled for ambulatory colonoscopy were included to study. All patients received midazolam 1 mg intravenous. After two minutes in Group R (remifentanil/midazolam, n=18) remifentanil bolus (10 microg) and infusion 0.03 microg kg(-1) min(-1) were administered until adequate sedation level was achieved. In Group T (tramadol/midazolam, n=18) iv tramadol 50 mg was given concurrently. During procedure 2 L/min oxygen was supplemented via face mask to all patients. Haemodynamic variables, respiratory depression, level of sedation, postoperative recovery, patient and gastroenterologist satisfaction were surveyed. Patients were asked to verbally rate their level of pain, on an 10-point numerical rating scale (1=no pain, 10=severe pain). Chi-square, student t test, and mann whitney U test were used for statistical analysis. Colonoscopy was carried out successfully in all patients. There were no episodes of desaturation or airway compromise. Haemodynamic parameters were similar in both groups. Sistolic arterial and diastolic arterial pressures were increased at 10 and 15 minutes in all patients (P<0.05). There were no significant changes in heart rate in both groups. The level of sedation in group R was higher than group T during colonoscopy. The patients in group T had higher pain scores. Gastroenterologist satisfaction and patient satisfaction were similar in both groups. Our results suggests that, sedoanalgesia with midazolam/remifentanil may be an alternative to sedoanalgesia with midazolam/tramadol for colonoscopy.
