Intraoperative magnetic resonance imaging in glioma surgery: a single-center experience.

PURPOSE: To investigate the effect of intraoperative magnetic resonance imaging (Io MRI) on overall and progression-free survival (OS and PFS), on the extent of resection (EOR) in patients with glioma, and impact of the radiological diagnosis on the decision to continue the surgery when a residual mass was detected on Io MRI. METHODS: The study comprised 153 glioma patients who received surgical treatment between 2013 and 2023. One-hundred twenty-five of them had Io MRI guidance during surgery. The remainder 28 patients constituted the control group who did not undergo Io MRI. All patients' age at surgery, gender, initial radiological diagnosis, primary tumor localization, EOR, last histopathological diagnosis, and the follow-up periods were recorded. RESULTS: The rate of tumor recurrence in Io MRI cases was significantly lower compared to the cases in the control group (p < .0001). It was decided to continue the operation in 45 Io MRI applied cases. This raised the gross total resection (GTR) rate from 33.6% to 49.6% in the Io MRI group. The frequency of GTR was significantly higher in patients with an initial radiological diagnosis of low grade glioma than those with high grade glioma. The shortest OS was seen in occipital gliomas. CONCLUSION: In this study, the convenience provided by the high-field MRI device was explored and proven both in reducing the tumor burden, increasing the PFS, and providing the surgeon with a maximal resection in the first operation.

Female Urethroplasty with a Buccal Mucosa Graft using a Supraurethral Approach.

INTRODUCTION AND HYPOTHESIS: In the setting of recurrent female urethral stricture, urethroplasty offer the best chance of cure. However, which approach (dorsal or ventral) and which tissue (buccal mucosa, vaginal graft, vaginal flap) remain areas of controversy. In this article and accompanying video, we describe female urethroplasty with a supraurethral approach using a buccal mucosa graft. METHODS: A stricture of 3 cm in length was observed in the mid urethra. A supraurethral semi-lunar incision was made and dissection was performed up to the stricture. A dorsal urethrotomy was performed and a 3 × 2 cm oral mucosal graft was harvested from the left cheek. The mucosal graft was anastomosed to both urethral edges with running sutures. The graft was fixed to the supraurethral tissue with quilting sutures. A urethral catheter and a suprapubic catheter were left in place for 3 weeks. RESULTS: Following removal of the catheters, the patient was able to void satisfactorily with no incontinence. No complications were observed in the urethral area or at the graft harvest site. CONCLUSIONS: Buccal mucosa graft urethroplasty with a supraurethral approach is a reliable method in the treatment of female urethral stricture.

The effect untreated right subclinical varicocele on the outcomes of contralateral left clinical varicocelectomy in infertile patients.

PURPOSE: The management of infertile patients with unilateral subclinical varicocele (SCV) and contralateral clinical varicocele (CV) remains controversial. We aimed to evaluate the effect of untreating SCV on the outcome of contralateral clinical varicocelectomy in infertile patients with oligoasthenozoospermia (OA). MATERIALS AND METHODS: Infertile patients with the diagnosis of OA who underwent left varicocelectomy were retrospectively evaluated. While all patients in the study had left clinical varicocele (LCV), some patients had concomitant right SCV. Patients were divided into two groups according to the presence or absence of a right SCV accompanying LCV as group 1; (LCV n = 104) or group 2; (LCV with right SCV, n = 74). Patients were evaluated with spermiogram parameters, pregnancy rates and serum levels of follicle stimulating hormone, luteinizing hormone, total testosterone at the first year of the follow-up. RESULTS: The mean sperm concentration increased significantly in both groups. However, group 1 showed significantly greater improvement than group 2. The ratio of progressive motile sperm in group 1 was increased significantly whereas no significant change was shown in group 2. Both the spontaneous pregnancy rate and the pregnancy rate with ART were statistically lower in the group of patients with right SCV. No statistically significant difference was detected in serum hormone levels in both groups after varicocelectomy operations. CONCLUSIONS: Untreated right SCV may have adverse impact on the outcomes of left clinical varicocelectomy. In this context, the right testis can be considered in terms of treatment in patients with right SCV accompanying left CV.

Correlation between Prostate Cancer Positive Cores and 68Ga-PSMA Distribution in Prostate Gland.

INTRODUCTION: The purpose of our study was to evaluate reliability of 68Ga-labeled prostate-specific membrane antigen positron emission tomography (68Ga-PSMA PET/CT) and identify appropriate SUVmax cutoff values in order to use for diagnosis, especially in patients remained clinically suspicious for prostate cancer (PCa). METHODS: Eighty-four patients applied 68Ga-PSMA PET/CT subsequent to transrectal ultrasound-guided prostate biopsy (TRUS-bx) involved in this study retrospectively. 68Ga-PSMA PET/CT imagings were analyzed by a nuclear medicine physician, and region of interests were drawn manually in prostate diagrams including 6 segments for each patient. These marked diagrams were analyzed with histopathology reports TRUS-bx. 504 segments were grouped with Gleason scoring system, and all groups were compared with mean SUVmax values. RESULTS: Mean SUVmax value of Gleason grade group 1 (GG1, n: 352 segments) was 6.6 (±4.6) and significantly lower than the other groups (p < 0.001). No significant difference was detected within GG2-5 groups (p > 0.05). According to receiver operating characteristic curve analysis, SUVmax cutoff values were 1.0 (AUC: 0.961) for tumor detection, yielding a sensitivity, specificity, positive predictive value, negative predictive value of 99.4%, 92.1%, 96.5%, 98%, respectively, and 4.2 (AUC: 0.853) for detection of clinically significant PCa with 88.8%, 62.4%, 84.5%, and 71%, respectively. Although tumor percentage of biopsy core and Gleason group were correlated with SUVmax uptake, but patient age was not. CONCLUSION: 68Ga-PSMA PET appears to be a reliable option for diagnosis and disease management in PCa and can be considered especially in discrimination of csPCa, and patients remained suspicious for disease.

Low-Grade Injury following Testicular Torsion: A Multicenter Study Confirming a Disturbing Possibility.

INTRODUCTION: There is an ongoing debate whether to perform orchiectomy or orchidopexy following testicular torsion (TT) in cases where the testis seems non-viable. The main problem is lack of objective criteria defining testicular viability. The aim of this study was to investigate the grade of injury in orchiectomy specimens obtained from cases of TT and its association with clinical findings. METHODS: This multicenter retrospective study involved double-blinded reassessment of the patient files and the pathological specimens using Mikuz classification to analyze the relation between clinical and pathological findings. RESULTS: A total of 289 patient charts from 14 centers were reviewed and 228 were included in this study. Twenty (8.8%) patients had grade 1 injury which refers to reversible injury. The clinical findings of these 20 patients were compared to 208 patients with higher grades of injury. As expected, there was statistically significant difference regarding duration of symptoms (p < 0.001); however, range was wide in both groups (as long as 96 h for grade 1 and as short as 7 h for higher grades). There was no statistically significant difference in any other variable including age (median 14 for both, p = 0.531), symptoms (pain: 19/20 vs. 189/202, p = 0.801; swelling: 13/19 vs. 168/197, p = 0.094), absence of blood flow in Doppler US (15/19 vs. 164/197, p = 0.635), or degree of torsion (median 720° for both, p = 0.172). CONCLUSION: Our study revealed necessity for better criteria to define viability of testis following TT. Histopathological injury appeared to be reversible even in some patients with more severe perioperative findings, late admission, or high degree of twisting. Our findings support the tendency for testicular fixation instead of orchiectomy as none of the clinical or perioperative findings could be attributed to high-grade injury.

Benign Multicystic Peritoneal Mesothelioma: Two Rare Cases and Review of the Literature.

BACKGROUND: Benign multicystic peritoneal mesothelioma is a multiloculated cystic mass which originates from the peritoneum. This rare tumor is usually seen in women of childbearing age and has a high recurrence rate after surgery. CASE PRESENTATION: We present two benign multicystic peritoneal mesothelioma cases with different imaging modalities, which were also pathologically proven. CONCLUSION: The imaging features which may be diagnostic should be well known as there are very few reports regarding this entity.

Diffuse generalized venulitis as the primary pathology of Behçet's disease: A comprehensive magnetic resonance venography study.

OBJECTIVE: Behçet's Disease (BD) is a chronic multisystem vasculitis that manifests with destructive inflammation affecting the eyes, central nervous system, and blood vessels. The pathology of vein involvement in BD is poorly characterized. Magnetic resonance (MR) venography gives more comprehensive information about deep veins and adjacent tissues. In this study, we aimed to characterize vein involvement and evaluate the diagnostic utility of MR venography in BD. METHODS: Sixty-five BD patients who fulfilled the International Study Group (ISG) criteria and 20 healthy control subjects were enrolled. Inferior vena cava (IVC), common iliac veins (CIV), external (EIV) and internal iliac veins (IVV), common femoral veins (CFV), femoral veins (FV), and greater saphenous veins (GSV) of BD patients and healthy controls were evaluated with MR venography and ultrasonography for the presence pathologic features, luminal thrombi, vessel wall changes, and perivascular abnormalities. RESULTS: 33 vascular and 32 non-vascular BD patients (mean age 39.3 ± 11.3 years and 48 [73.8%] male) were enrolled. MR venography revealed diffuse concentric thickening of the walls of IVC, CIV, EIV, IIV, CFV, FV, and GSV in BD (healthy controls vs. BD p<0.05 for all vein segments). MR venography provided additional information about veins and perivascular tissues like contrast enhancement, enlarged lymph nodes, and seminal vesicle vascularization, which were remarkably more frequent in vascular BD than non-vascular BD and healthy controls. CONCLUSION: The results of our study suggest that the involvement of the venous system is diffuse and generalized in BD, and demonstration of venulitis might help diagnose the disease.

How many cores should be taken from each region of interest when performing a targeted transrectal prostate biopsy?

Background: The number of core biopsies required per region of interest (ROI) is controversial, as is the localization of the core to be taken from a lesion. This study aimed to determine the ideal biopsy core number and location in a multiparametric magnetic resonance imaging guided targeted prostate biopsy (TPB), without reducing the clinically significant prostate cancer (csPC) detection rate. Materials and methods: Data of patients who had PI-RADS ≥3 lesions on multiparametric magnetic resonance imaging and underwent a TPB in our clinic between October 2020 and January 2022 were reviewed, retrospectively. The first and second cores were taken from the central part of the ROI, whereas the third and fourth cores were taken from the right and left peripheries of the ROI. We compared the csPC detection success of single-, 2-, 3-, and 4-core samplings. Results: Software-based transrectal TPB was performed on 251 ROIs in a total of 167 patients. Internal Society of Urological Pathology Grade Group ≥2 cancer was detected in at least one core in 64 (25.4%) lesions. Moreover, csPC was detected in 42 (65.6%) ROIs in first-core biopsies; in 59 (92.2%) ROIs in first- and second-core biopsies; in 62 (96.9%) ROIs in first-, second-, and third-core biopsies; and in 64 (100%) ROIs in first-, second-, third-, and fourth-core biopsies. Using McNemar's test for comparison, a significant difference was found in terms of csPC detection success between performing first-core and second-core biopsies (65.6 - 92.2%, p < 0.001); by contrast, no significant difference was observed in csPC detection success between 2-core and 3-core biopsies (92.2% - 96.9%, p = 0.24). Furthermore, no significant difference existed between performing second-core and fourth-core biopsies in terms of csPC detection success (92.2%-100%, p = 0.07). Conclusion: We concluded that taking 2-core biopsies from the center of each ROIs during a transrectal TPB is sufficient for diagnosing csPC.

The possible relation between temporal muscle mass and glioblastoma multiforme prognosis via sarcopenia perspective.

BACKGROUND: The optimal sarcopenia measurement method in patients with a diagnosis of glioblastoma multiforme (GBM) is unknown. It has been found that temporal muscle thickness (TMT) may reflect sarcopenia and be associated with survival, but the relationship between temporal muscle area (TMA) and GBM prognosis has never been evaluated before. The primary outcome of the study was to evaluate the relationship between TMA/TMT and overall survival (OS) time in newly diagnosed GBM patients. METHODS: The data of patients who presented at the university hospital between January 2009 and January 2019 with a confirmed diagnosis of glioblastoma multiforme at the time of diagnosis were analyzed retrospectively. Temporal muscle thickness and TMA were measured retrospectively from preoperative MRIs of patients diagnosed with GBM. Due to the small number of patients and the failure to determine a cut-off value with acceptable sensitivity and specificity using ROC analysis, the median values were chosen as the cut-off value. The patients were basically divided into two according to their median TMT (6.6 mm) or TMA (452 mm2 ) values, and survival analysis was performed with the Kaplan-Meier analysis. RESULTS: The median TMT value was 6.6 mm, and the median TMA value was 452 mm2 . The median overall survival (OS) was calculated as 25.8 months in patients with TMT < 6.6 mm, and 15.8 months in patients with TMT ≥ 6.6 mm (p = 0.29). The median overall survival (OS) of patients with TMA < 452mm2 was 26.3 months, and the group with TMA ≥ 452mm2 was 14.6 months (p = 0.06). The median disease-free survival was 18.3 months (%95 CI: 13.2-23.4) in patients with TMT < 6.6mm, while mDFS was 10.9 (%95 CI: 8.0-13.8) months in patients with TMT ≥ 6.6mm (p = 0.21). The median disease-free survival was found to be 21.0 months (%95 CI: 15.8-26.1) in patients with TMA < 452 mm2 and 10.5 months (%95 CI: 7.8-13.2) in patients with TMA ≥ 452 mm2 (p = 0.018). DISCUSSION: No association could be demonstrated between TMT or TMA and OS of GBM patients. In addition, the median DFS was found to be longer in patients with low TMA. There is an unmet need to determine the optimal method of sarcopenia in GBM patients.

Does STING failure affect short-term graft functions in renal transplant patients: a single-center study.

PURPOSE: The aim of the present study was to evaluate outcomes of symptomatic VUR treatment in transplant patients, compare open and endoscopic approaches in terms of graft functions, success rates, complications and recurrent UTIs. METHODS: 67 patients who undergone only STING and STING followed redo UNC due to symptomatic VUR after kidney transplantation were included into the investigation. Patients who had lower urinary tract dysfunctions were excluded from the trial. For 67 patients, baseline and before final surgery and 3rd month creatinine and GFR levels were recorded. Twenty-six of those 67 patients had redo UNC due to failed STING. The data of those patients were compared with the remaining 41 patients who had only STING. RESULTS: In both groups no statistically significant variations in serum creatinine and GFR levels were detected during follow-up (p > 0.05). Serum levels after STING and in the 3rd month of redo UNC were compared. Although variation was observed in serum creatinine levels and in GFR levels, was not statistically significant (p: 0.59 and p: 0.23). The success rate of STING was %61.1 in 67 patients, and was not significantly different when three VUR grade groups (Grade 3 n:17, Grade 4 n:24, Grade 5 n:36) were compared (p > 0.05). CONCLUSION: The present study revealed that subureteral endoscopic injection is cost effective and safe for the first-line treatment due to its minimally invasive nature, does not cause delay which leads to deterioration of graft functions. Redo-UNC has acceptable morbidity and complication rates, should be considered when STING is failed.

Automatic segmentation of COVID-19 from computed tomography images using modified U-Net model-based majority voting approach.

The coronavirus disease (COVID-19) is an important public health problem that has spread rapidly around the world and has caused the death of millions of people. Therefore, studies to determine the factors affecting the disease, to perform preventive actions and to find an effective treatment are at the forefront. In this study, a deep learning and segmentation-based approach is proposed for the detection of COVID-19 disease from computed tomography images. The proposed model was created by modifying the encoder part of the U-Net segmentation model. In the encoder part, VGG16, ResNet101, DenseNet121, InceptionV3 and EfficientNetB5 deep learning models were used, respectively. Then, the results obtained with each modified U-Net model were combined with the majority vote principle and a final result was reached. As a result of the experimental tests, the proposed model obtained 85.03% Dice score, 89.13% sensitivity and 99.38% specificity on the COVID-19 segmentation test dataset. The results obtained in the study show that the proposed model will especially benefit clinicians in terms of time and cost.

The Impact of COVID-19 Pandemic on Urological Emergencies, 8 Months Results of a Multicenter Retrospective Study From Turkey.

Objectives: We aimed to reveal the change of urological emergencies during the COVID-19 pandemic compared to the same period of the previous year. Methods: The number of admissions to the emergency department (ED), admissions to the urology outpatient clinic, emergency urological consultations, and urological and emergency urological surgeries during the periods April-November-2019 and April-November-2020 were recorded. The data of the COVID-19 period were compared with the previous year. Results: While the number of admissions to the urological outpatient clinic was 160,447 during the COVID period, it was 351,809 during the non-COVID period. The number of admissions to the ED decreased from 3.2 million to 2.4. The number of admissions to the urology outpatient clinic significantly decreased by 54% during the pandemic (p=0.001). Percutaneous cystostomy performed due to acute urinary obstruction decreased by 27.96%, double J stent, nephrostomy decreased by 16.61%, and ureterorenoscopy decreased by 12.26%. Urogenital trauma also decreased. On the contrary, surgical procedures performed due to penile fracture, gross hematuria, Fournier gangrene, and testicular torsion increased. Conclusion: During the COVID-19 pandemic, a significant decrease was observed in non-COVID patients' admissions to the emergency and urology department, and in urologic surgeries.

Rare emergency in children: Priapism and stepwise treatment approach.

BACKGROUND: Priapism is a rare condition in children and the treatment algorithm is controversial in this age group. Herein, we report eight cases with low-flow priapism and our stepwise treatment approach in light of literature. METHODS: We present a simple stepwise treatment for low-flow priapism including five steps. Step 1: Cold compress and analgesia while evaluation the priapism and its etiology. Step 2: Corporal aspiration and adrenaline infusion in the ward. Step 3: Modified Winter shunt in the same place. Step 4: Ketamine application and caudal block in the operating room. Step 5: Sapheno-cavernous (Grayhack) shunt. Eight cases with low-flow priapism were reviewed retrospectively. Symptoms, duration of tumescence, the interventions, and step that provide detumescence were recorded. RESULTS: The mean age of patients was 8.5 years (1-17 y). The median time of the priapism before admission was 15 h (4-165 h). The etiological factors were sickle cell disease, hemodialysis due to chronic renal failure, and factor V Leiden mutation in three patients. Detumescence was achieved in one patient at Step 2, in two patients at Steps 3, 4, and 5, respectively. Rigidity of cavernous body was observed in one patient in long-term follow-up. CONCLUSION: Low-flow priapism is a urological emergency that may cause erectile dysfunction. Treatment options should be selected according to a protocol that prevents time loss and avoids more invasive treatment in unnecessary situations. Our algorithm with simple nature and its steps from less invasive to more invasive procedures may be an alternative for the treatment of low-flow priapism.

Which one is better for predicting extraprostatic extension on multiparametric MRI: ESUR score, Likert scale, tumor contact length, or EPE grade?

PURPOSE: To evaluate the European Society of Urogenital Radiology (ESUR) score, the Likert scale, tumor contact length (TCL) > 1 cm, and EPE (extraprostatic extension) grade in predicting EPE at multiparametric magnetic resonance imaging (mp-MRI). METHODS: Seventy-nine patients who underwent 3-T MRI and were histopathologically confirmed by microblocks were enrolled in this retrospective study. The index lesions were interpreted by two experienced radiologists. Apparent diffusion coefficient (ADC) values were also noted. Weighted κ statistics were used to compare interreader agreement. Univariate logistic regression analysis was performed to define independent predictors of EPE status. Multivariable logistic regression and receiver operating characteristic (ROC) analysis were performed to compare the MRI-based methods and clinical variables (ISUP grade, prostate volume and PSA density) + MRI-based methods for pathologic EPE prediction by using the area under the curve (AUC) value. RESULTS: The mean age was 64.5 years ± 6.2. 33/79 (41.8%) patients had pathologic EPE. As ESUR score showed weak interreader agreement (κ = 0.537), Likert scale, TCL, and EPE grade showed moderate agreement (κ = 0.608, κ = 0.747, κ = 0.647 respectively). Univariate ROC analysis result showed that all MRI-based score systems, mean ADC value, the ISUP grade, prostate volume, PSA density were the best variables in predicting EPE. ROC analysis results of four MRI-based methods showed good diagnostic performance. At multivariate analysis, all clinical models showed excellent diagnostic performance. CONCLUSION: All four MRI-based methods had good diagnostic performance. Furthermore, consisting of both qualitative and quantitative parameters and being less reader experience dependent, EPE grade was a promising method in predicting EPE. All clinical models showed excellent diagnostic performance.

The impact of anti-TNF treatment on Wnt signaling, noggin, and cytokine levels in axial spondyloarthritis.

INTRODUCTION: Anti-tumor necrosis factor (anti-TNF) agents are commonly used in treatment of axial spondyloarthritis (axSpA), but clinical and radiological improvement is not achieved in all patients. We aimed to investigate the impact of anti-TNFs on inflammatory and noninflammatory parameters in patients with axSpA. METHODS: In this longitudinal study, 30 biologic naïve axSpA patients with high disease activity and 30 healthy controls were enrolled. All patients were treated with anti-TNF agents for 6 months. ASDAS-CRP, BASDAI, BASFI, BASMI, patient and physician global assessments were evaluated. C-reactive protein, COX2, TNF-α IL-6, IL-17, IL-22, IL-23, IL-33, sclerostin, dickkopf-1, and noggin levels were evaluated at baseline and at 6 months of anti-TNF treatment. RESULTS: At baseline, axSpA patients had significantly higher median (IQR) TNF-α levels, 34.4 (31.4-37.03) vs. 18.1 (12.1-28.4) pg/ml (p < 0.001), and lower DKK1, 446.7 (356.9-529.3) vs. 1088.7 (951.7-1244.4) pg/ml, and sclerostin, 312.4 (140.8-412.7) vs. 412.3 (295.4-512.8) pg/ml, compared to healthy controls (all p < 0.001). The median (IQR) serum levels of IL-17, IL-22, and IL-33 increased significantly after 6 months of anti-TNF treatment, from 93.3 (85.1-104.8) to 102.1 (86.6-114.6) pg/ml (p = 0.026), 159.2 (151.9-178.4) to 183.5 (156.3-304.6) pg/ml (p = 0.033), and 127.8 (106.6-186.1) to 147.06 (128.5-213.4) pg/ml (p = 0.016), respectively. Sclerostin and DKK-1 levels increased significantly after anti-TNF treatment from 312.4 (140.8-412.7) to 405.1 (276.3-452.5) pg/ml (p = 0.018) and 446.7 (356.9-529.3) to 881.3 (663.1-972.2) pg/ml (p < 0.001), while there was no significant change in noggin level. CONCLUSIONS: Many inflammatory cytokines increase after anti-TNF treatment and noggin is not affected by anti-TNF treatment in AxSpA. Noggin might be a therapeutic target in patients with axSpA. KEY POINTS: • Anti-TNF therapy is not sufficient for complete blockage of the inflammatory process in axial spondyloarthritis. • The increase in IL-17, IL-22, and IL-33 may decrease the efficiency of anti-TNF therapy. • Noggin might be a therapeutic target as a complementary or alternative approach to anti-TNF therapy in axial spondyloarthritis.

Posterior Circulation Alberta Stroke Program Early Computed Tomography Score (pc-ASPECT) for the Evaluation of Cerebellar Infarcts.

BACKGROUND: Patients with cerebellar ischemic stroke may be misdiagnosed and may exhibit a delayed time to acute stroke treatment compared with patients with anterior circulation ischemic stroke. The posterior circulation Alberta stroke program early computed tomography score (pc-ASPECT) score has been used to evaluate hyperacute stroke, much as the ASPECT in anterior circulation stroke recently. Our main objective was to evaluate the associations of the clinical and etiological characteristics of ischemic cerebellar infarction patients on admission with their pc-ASPECT scores, as well as the correlations of the pc-ASPECT score with morbidity and mortality rates. MATERIALS AND METHODS: We include 114 patients with cerebellar infarction who underwent 1 year of follow-up into the study. RESULTS: Patients with a pc-ASPECT score <7 were more likely to present with impaired consciousness ( P <0.001), multiple posterior circulation infarcts ( P <0.001), hydrocephalus ( P <0.001), lesions of the vermis ( P =0.028), and peduncle ( P =0.024), perfusion deficits in the total of posterior inferior cerebellar artery, anterior inferior cerebellar artery, superior cerebellar artery ( P <0.05), and basilar artery stenosis ( P =0.005), ischemia in additional anatomical structures in the posterior circulation ( P <0.001) compared with those with a score ≥7. CONCLUSIONS: Although the pc-ASPECT score alone is insufficient in some cases like vertebral artery dissection, using it together with the National Institutes of Health Stroke Scale (NIHSS) score and clinical findings may be beneficial during the hyperacute period of cerebellar ischemia. Presentation with impaired consciousness, basilar artery pathologies, vermian ischemia, and ischemia in additional anatomical structures in the posterior circulation other than the cerebellum appeared as important clinical and radiologic parameters predicting long-term prognosis.

Irregularity in Plantar Fascia, Muscle Edema and Tendon Thickness in Patients with High-Risk for Diabetic Foot.

AIM: To investigate the alterations in the plantar fascia (PF), intrinsic muscles, and tendons in the feet of patients at high risk for developing diabetic foot. METHODS: The healthy feet of 22 patients with type 2 diabetes, who had developed diabetic foot ulcers on a single foot without any pathology on the contralateral extremity, and those of 22 healthy volunteers were evaluated by magnetic resonance imaging. The volume of the Achilles tendon (AT), the surface area of the PF, the thickness of AT, flexor hallucis longus, flexor digitorum longus, tibialis posterior, and peroneus longus tendons, irregularity in the PF, and edema of intrinsic foot muscles were examined. RESULTS: Nineteen patients (86%) had irregularity in the PF, whereas none of the healthy controls had any (p<0.001). Intrinsic muscle edema was more common in the group with diabetes (p=0.006). The volume of AT and the surface area of PF were decreased in patients with peripheral arterial disease (PAD) (p<0.05). Patients with diabetes mellitus but without PAD had a larger surface area of PF than that of controls (p<0.05). There were no differences in the volume of AT, the surface area of the PF, and other tendon thickness between the groups. CONCLUSION: Irregularity in the PF and muscle edema may indicate a high risk for the diabetic foot. The presence of PAD may lead to regression in the structure of AT and PF.

[Comparison of magnetic resonance imaging-transrectal ultrasound fusion prostate biopsy with standard systematic biopsy: A single center experience.] / Comparación de la resonancia magnética biopsia próstata transrectal guiada por ultrasonido con fusión de resonancia magnética con la biopsia próstata sistemática: resultados de un solo centro.

OBJECTIVE: To compare systematic biopsy with MRI-TRUS fusion prostate biopsy in terms of cancer detection rates. PATIENTS AND METHODS: The data of the patients who had a Prostate Imaging Reporting and Data System (PI-RADS) score of 3 or more lesions on mpMRI and underwent MRI-TRUS fusion biopsy with simultaneous 12-core standard systematic biopsy from June 2016 to June 2019 in our tertiary center were retrospectively reviewed. Clinical, radiological and pathological data were recorded. Statistical difference among the groups was determined by using McNemar tests. RESULTS: A total of 344 patients were included in the study. As a result of transrectal targeted and systematic combined biopsy, 117 patients were diagnosed with prostate cancer. Benign pathology rates in patients with PI-RADS 3, PI-RADS 4, and PI-RADS 5 lesions were 93.8%, 68.5%, and 46.4%, respectively. Patients were divided into two groups as ISUP grade 1 and ISUP grade ≥2 and cancer detection rates (CDRs) were found significantly higher in transrectal targeted biopsy compared with the systematic biopsy (12.5% vs. %6.4, p=0.007 and 17.4% vs. 8.7%, p<0.001, respectively). Targeted biopsy CDRs were found significantly higher in the high PSA density group (24.5% vs. 41.4%, p=0.001) unlike the systematic biopsy. CONCLUSION: Transrectal targeted biopsy was superior to systematic biopsy in the diagnosis of prostate cancer. Clinicians should be more selective when making a biopsy decision for patients with PI-RADS 3 lesions. PSA density can be used as a criterion for patient selection for targeted biopsy.

OBJETIVO: Comparar la biopsia sistemática próstata con fusión de resonancia transrectal vs la biopsia prostática sistemática, en términos de detección de cáncer de próstata.PACIENTES Y MÉTODOS: Los datos de pacientes con RNM y PIRADS (Prostate Imaging Reporting and Data System) 3 o más y que recibieron una biopsia prostática transrectal con biopsia simultanea de 12 cilindros sistemática entre junio 2016 y junio 2019 en nuestro centro académico fueron retrospectivamente revisados. Los datos radiológicos, clínicos y patológicos fueron también revisados. La diferencia estadística entre los grupos fue determinada utilizando los tests de McNemar. RESULTADOS: Un total de 344 pacientes fueron incluidos en el estudio. Como resultado de la biopsia transrectal sistemática y dirigida, 117 pacientes fueron diagnosticados de cáncer de próstata. Las tasas de patología benigna en pacientes con PIRADS 3, PIRADS 4 y PIRADS 5 fueron de 93,8%, 68,5%, y 46,4%, respectivamente. Los pacientes fueron divididos en 2 grupos como ISUP grado 1 y ISUP grado 2 o más, las tasas de detección de cáncer fueron superiores en los pacientes que recibieron una biopsia transrectal dirigida vs sistemática (12,5% vs. 6,4%, p=0,007 y 17,4% vs. 8,7%, p<0,001, respectivamente). La detección de cáncer por biopsia dirigida fue superior en pacientes con alta densidad de PSA (24,5% vs. 41,4%, p=0,001) a diferencia de la biopsia sistemática.CONCLUSIÓN: La biopsia transrectal dirigida fue superior a la biopsia sistemática en el diagnóstico de cáncer de próstata. Los clínicos deberían ser más selectivos al tomar la decisión de qué biopsia hacer en un paciente con PIRADS 3. La densidad de PSA se puede utilizar como criterio para realizar una biopsia dirigida.

Comparison of magnetic resonance imaging-transrectal ultrasound fusion prostate biopsy with standard systematic biopsy: a single center experience / Comparación de biopsia de próstata por fusión de imágenes por resonancia magnética-ultrasonido transrectal con biopsia sistemática estándar: experiencia en un solo centro

Objetive: To compare systematic biopsy with MRI-TRUS fusion prostate biopsy in terms ofcancer detection rates. Patients and methods: The data of the patientswho had a Prostate Imaging Reporting and Data System (PI-RADS) score of 3 or more lesions on mpMRI andunderwent MRI-TRUS fusion biopsy with simultaneous12-core standard systematic biopsy from June 2016to June 2019 in our tertiary center were retrospectivelyreviewed. Clinical, radiological and pathological datawere recorded. Statistical difference among the groupswas determined by using McNemar tests. Results: A total of 344 patients were included in thestudy. As a result of transrectal targeted and systematiccombined biopsy, 117 patients were diagnosed withprostate cancer. Benign pathology rates in patients withPI-RADS 3, PI-RADS 4, and PI-RADS 5 lesions were93.8%, 68.5%, and 46.4%, respectively. Patients weredivided into two groups as ISUP grade 1 and ISUP grade≥2 and cancer detection rates (CDRs) were found significantly higher in transrectal targeted biopsy comparedwith the systematic biopsy (12.5% vs. %6.4, p=0.007and 17.4% vs. 8.7%, p<0.001, respectively). Targetedbiopsy CDRs were found significantly higher in the highPSA density group (24.5% vs. 41.4%, p=0.001) unlikethe systematic biopsy. Conclusions: Transrectal targeted biopsy was superior to systematic biopsy in the diagnosis of prostate cancer. Clinicians should be more selective when making abiopsy decision for patients with PI-RADS 3 lesions. PSAdensity can be used as a criterion for patient selectionfor targeted biopsy.(AU)

Objetivo: Comparar la biopsia sistemática próstata con fusión de resonancia transrectal vs labiopsia prostática sistemática, en términos de detecciónde cáncer de próstata. Pacientes y métodos: Los datos de pacientes conRNM y PIRADS (Prostate Imaging Reporting and DataSystem) 3 o más y que recibieron una biopsia prostáticatransrectal con biopsia simultanea de 12 cilindros sistemática entre junio 2016 y junio 2019 en nuestro centroacadémico fueron retrospectivamente revisados. Los datos radiológicos, clínicos y patológicos fueron tambiénrevisados. La diferencia estadística entre los grupos fuedeterminada utilizando los tests de McNemar. Resultados: Un total de 344 pacientes fueron incluidos en el estudio. Como resultado de la biopsiatransrectal sistemática y dirigida, 117 pacientes fuerondiagnosticados de cáncer de próstata. Las tasas de patología benigna en pacientes con PIRADS 3, PIRADS 4y PIRADS 5 fueron de 93,8%, 68,5%, y 46,4%, respectivamente. Los pacientes fueron divididos en 2 gruposcomo ISUP grado 1 y ISUP grado 2 o más, las tasas dedetección de cáncer fueron superiores en los pacientesque recibieron una biopsia transrectal dirigida vs sistemática (12,5% vs. 6,4%, p=0,007 y 17,4% vs. 8,7%,p<0,001, respectivamente). La detección de cáncerpor biopsia dirigida fue superior en pacientes con altadensidad de PSA (24,5% vs. 41,4%, p=0,001) a diferencia de la biopsia sistemática. Conclusion: La biopsia transrectal dirigida fuesuperior a la biopsia sistemática en el diagnóstico decáncer de próstata. Los clínicos deberían ser más selectivos al tomar la decisión de qué biopsia hacer en unpaciente con PIRADS 3. La densidad de PSA se puedeutilizar como criterio para realizar una biopsia dirigida.(AU)
