The distance between the anatomical landmarks was measured, and the error was found by averaging the distances across all patients.

The average error during co-registration was 1.25 mm. This error was significantly larger than the error resulting from image standardization (0.19 mm) and was worse in the anterior-posterior direction.

The image fusion errors found in this analysis were nontrivial. Although the estimated error may be inflated, it is sig-nificant enough that users must be aware of this potential inaccuracy, and developers of proprietary software should provide details about the magnitude and direction of co-registration errors.

From May to December 2019, a literature review of the urinary system iatrogenic injury problem was performed. The most cited, representative articles in PubMed, Scopus, and WoS databases dedicated to this problem were selected. Urinary system iatrogenic injuries include ureter, bladder, urethra, and kidney traumas. It is widely thought that the main causes of such injuries are urological, obstetric, gynecological, and surgical operations on the retroperitoneal space, pelvis, or perineum.

The purpose of the study is to describe all aspects of the iatrogenic injure problem, under the established scheme and for each of the most damaged organs the urethra, bladder, kidney, and ureter. The treatment of confirmed iatrogenic injuries largely depends on the period of its detection. Modern medical procedures provide conservative or minimally invasive treatment. selleck products An untimely diagnosis worsens the treatment prognosis. "Overlooked" urinary system trauma is a serious threat to society and a particular patient. Thus, incorrect or traumatic catheterization can lead to infection (RR 95%) and urethral stricture (RR ≥11-36%), and percutaneous puncture nephrostomy can cause the risk of functional renal parenchyma loss (median 5%), urinary congestion (7%), or sepsis (0.6-1.5%).

Lost gain, profits, long-term and expensive, possibly multistage treatment, stress and depression, and the risks of suicide put a heavy financial, moral, and ethical burden on a person and society. Also, iatrogenic injury might have legal consequences.

Thus, the significant problem of urinary tract iatrogenic injuries is still difficult to solve. There is a need to implement mandatory examining algorithms for patients at risk, as well as the multidisciplinary principle for all pelvic surgery.

Prostate cancer (PCa) is the most common malignancy in men. The multiparametric MRI (mpMRI) significantly improved the diagnostic approach of PCa. Although PCa is highly likely to be present in prostate imaging-reporting and data system (PI-RADS) 5 lesions, there are up to 18% of PI-RADS 5 lesions with benign histopathology after targeted biopsy.

We present the case of a 66-year-old man who was referred to our hospital for MRI/ultrasound fusion-based targeted biopsy due to an elevated PSA and a PI-RADS 5 lesion described in the mpMRI. After 2 consecutive biopsies, the mpMRI target showed no malignancy. The lesion was described as PI-RADS 2 two years later.

This case demonstrates the risk of false-positive classified PI-RADS 5 lesions in the mpMRI and the challenge in some cases to distinguish between BPH nodules and cancer. Until today, a limited amount of studies exists concerning this issue. However, further studies are required to evaluate further characteristics associated with a higher possibility of histopathologically benign findings in PI-RADS 5 lesions.

The aim of the study was to investigate the expression and significance of microRNA-126, microRNA-21, FOXP3mRNA, acetylcholine receptor antibody (AChR-Ab), and interleukin 6 (IL-6) in peripheral blood of patients with myasthenia gravis (MG).

From September 2015 to March 2018, 60 patients with MG who were first diagnosed as MG were selected as the MG group, and 50 healthy people in the same period were selected as the normal group. RT-PCR technology was used to detect the relative expression of microRNA-126, microRNA-21, and FOXP3mRNA in peripheral blood mononuclear cells of the MG group and the control group. The EILISA and IPA technique was used to detect the expression levels of IL-6 and AChR-Ab in the peripheral serum of the 2 groups.

There were no differences between groups regarding patient's characteristics and baseline data. microRNA-21 and microRNA-126 are highly conserved in the human genome. microRNA-21, microRNA-126, FOXP3mRNA, AChR-Ab, and IL-6 are differentially expressed in the MG group and the control group (p < 0.05). microRNA-21 is positively correlated with AChR-Ab and IL-6 in MG patients (r = 0.746, 0.789, p < 0.05), but has no correlation with FOXP3mRNA (r = -0.249 p = 0.055), while micro-RNA-126 is positively correlated with FOXP3mRNA and negatively correlated with AChR-Ab and IL-6 (r = 0.526, -0.797, -0.801, p < 0.05).

Patients with MG have differential expression of microRNA-21 and microRNA-126 and may participate in the pathogenesis of MG by regulating pathways related to inflammatory immune response.
