Significant Prostate Cancer in Patients with PI-RADS Category 3 Lesions: A Single-Center, Retrospective Cohort Study.

PURPOSE:  The Prostate Imaging-Reporting and Data System (PI-RADS) category 3 is the most ambiguous lesion with a variable clinically significant prostate cancer (CsPCa) detection rate. Prostate-specific antigen density (PSAD) has been investigated as an adjunctive factor to improve the diagnostic efficiency of PI-RADS categories. This study aimed to investigate the utility of PSAD as an adjunctive factor in predicting CsPCA risk in patients with PI-RADS 3 lesions. MATERIALS AND METHODS: The patients with an initial PI-RADS 3 category lesion (n=142) scheduled for systematic and magnetic resonance imaging-guided prostate biopsy between 2018 and 2022 were retrospectively evaluated. Demographic and clinical variables, including PSAD, were collected. The rate of CsPCa was the primary outcome. The impact of PSAD on the CsPCa detection rate was the secondary outcome. RESULTS: The median age was 62 years. The rate of CsPCa was 8.5% (n=12). The patients with CsPCa have significantly lower prostate volüme and higher PSAD levels than those without CsPCa (p=0.016 and p=0.012). The cut-off values of PSAD in predicting CsPCa in all PI-RADS 3 patients and patients with CsPCa and clinically insignificant prostate cancer (n=26) were ≥0.181 ng/ml2. The sensitivity and specificity values for PSAD ≥0.181 ng/ml2 were of 75% (95% CI: 42.8%-94.5%) and 81.5% (95% CI: 73.4%-88.0%) in predicting CsPCa among PI-RADS 3 category.      Conclusion: PSAD values higher than 0.181 ng/ml2 can be used as an adjunctive clinical parameter in predicting CsPCa in patients with PI-RADS 3 lesions and differentiating CsPCa from clinically insignificant prostate cancer cases.

Is the robotic rehabilitation that is added to intensive body rehabilitation effective for maximization of upper extremity motor recovery following a stroke? A randomized controlled study.

BACKGROUND: Trunk stabilization, which is a factor that directly affects the performance of affected upper-limb movements in stroke patients, is of critical importance in the performance of selective motor control. AIMS: This study aimed to investigate the effects on upper-limb motor function of the addition of robotic rehabilitation (RR) and conventional rehabilitation (CR) to intensive trunk rehabilitation (ITR). METHODS: A total of 41 subacute stroke patients were randomly allocated to two groups: RR and CR. Both groups received the same ITR procedure. Following ITR, a robot-assisted rehabilitation program of 60 min, 5 days a week, for 6 weeks, was applied to the RR group, and an individualized upper-limb rehabilitation to the CR group. Assessments were made at baseline and after 6 weeks using the Trunk Impairment Scale (TIS), Fugl-Meyer Upper Extremity Motor Evaluation Scale (FMA-UE), and Wolf Motor Function Test (WMFT). RESULTS: Improvements were obtained in the TIS, FMA-UE, and WMFT scores for both groups (p < 0.001), with no superiority detected between the groups (p > 0.05). The RR group scores were relatively high, but not to a statistically significant. CONCLUSIONS: When added to intensive trunk rehabilitation, the robot-assisted systems, which are recommended as a stand-alone therapy method, produced similar results to conventional therapies. This technology can be used as an alternative to conventional methods under appropriate conditions of clinical opportunity, access, time management, and staff limitations. However, when RR is combined with traditional interventions such as intensive trunk rehabilitation, it is essential to investigate if the real effect is due to the robotic rehabilitation or the accumulation of positive effects of excessive movement or force spread associated with trained muscles. REGISTRATION: This trial was retrospectively registered in the ClinicalTrials.gov with NCT05559385 registration number (25/09/2022).

Primary Epiploic Appendagitis: Not Rare But Rarely Diagnosed Pathology.

OBJECTIVE: The aim of this study is to determine the clinical and laboratory parameters which may be suggestive of or even pathognomonic for primary epiploic appendagitis (PEA) and to discuss the diagnostic efficacy of ultrasound (US) compared to computed tomography (CT) in patients with PEA. MATERIALS AND METHODS: For this retrospective study, 92 patients diagnosed with PEA using US, CT or both modalities were included. All patient symptoms, clinical findings and laboratory parameters were reviewed. The CT and US images of the PEA were evaluated for lesion size and location, the relationship of the lesion to the colon and the distance of the lesion to the skin. RESULTS: There were 16 female and 76 male patients in the study group. The mean age was 35 years (range: 38-79 years). Well-localized abdominal pain was the primary symptom in all patients. The mean leukocyte count was 7857±1326 mm-3. The most frequent localization of PEA was sigmoiddescending colon junction (79/92). In patients who were examined by both US and CT, the size of the fatty central core was between 15-48 mm (mean:28.10 mm) and 9-22 mm (mean:15.07 mm) in its long-axis and short-axis diameter, respectively on US, whilst that by CT was between 15-46 mm (mean:26.88 mm) and 9-21 mm (mean:14.40 mm) in its long-axis and short-axis diameter, respectively. In patients who were examined by both US and CT, the mean distance of the lesions to the skin was 20.80 mm and 33.97 mm, respectively. All patients were treated conservatively with complete resolution of symptoms within a week of presentation. CONCLUSION: PEA is an unrare self-limiting condition that should be considered in the differential diagnosis of acute abdomen. To support clinicians and radiologists regarding PEA and its clinical, laboratory and radiological findings, targeted sonographic examination - which is radiation and contrast agent-free - could be highly sufficient for the diagnosis of PEA and may prevent unnecessary further imaging and mistreatment.

Spinal dural arteriovenous fistula: A rare cause of progressive myelopathy and bladder and bowel dysfunction.

Spinal dural arteriovenous fistula (SDAVF) is a rarely seen vascular lesion in the spinal cord and is often overlooked. If left untreated in the early stages, it is associated with severe morbidity and may lead to progressive myelopathy and bladder and bowel dysfunction. A 55-year-old male patient was admitted with complaints of lower extremity weakness, gait disorder, urinary retention, and stool retention. Based on physical examination and magnetic resonance imaging findings, a preliminary diagnosis of SDAVF was made. The diagnosis was confirmed by spinal angiography showing SDAVF on the left T6. Microsurgery was planned, once endovascular embolization failed. Although symptoms of progressive myelopathy and bladder and bowel dysfunction are rarely seen, SDAVF diagnosis should not be overlooked, and it should be kept in mind that early diagnosis and treatment prevent severe morbidities.
