Abstract During the late months of last year, a novel coronavirus was detected in Hubei, China. The virus, since then, has spread all across the globe forcing Word Health Organization (WHO) to declare COVID-19 outbreak a pandemic. In Spain, the virus started infecting the country slowly until rapid growth of infected people occurred in Madrid, Barcelona and other major cities. The government in an attempt to stop the rapssid spread of the virus and ensure that health system will not reach its capacity, implement strict measures by putting the entire country in quarantine. The duration of… More >

Abstract Chronic pain has a high prevalence rate and is difficult to treat because it is associated with personality, socio-psychological problems as well as physical pain, and thereby degrades one’s quality of life. This study aimed to determine whether psychosocial factors are associated with quality of life among outpatients with chronic pain. The subjects were selected from patients with chronic pain who were receiving outpatient treatment at the mental health department of a university hospital in Seoul, Korea. The participants were 100 patients and the data were collected using structured questionnaires. Patients’ quality of life More >

Abstract Cryotherapy, or more commonly known as cold therapy, is the use of low temperatures in medical treatment. The most prominent use of cryotherapy is for cryosurgery where application of very low temperatures is used to ablate diseased tissue (e.g., most commonly in dermatology). Recent research, however, shows that low temperature may modulate collagen fibers beyond the already known effects of extreme cooling on joint pain relieve and inflammation. The goal of this brief review is to outline the known effects of extreme cooling on molecular, fiber and cell physiology and to leverage these properties in… More >

Abstract Introduction: The aim of this study was to investigate demographic and clinical characteristics and outcomes of the treatments of the patients with an unusual presentation of testicular torsion (TT) and to clarify their peculiarities.
Material and methods: From January 1999 until December 2017, the case records of 149 patients who underwent surgery for TT were retrospectively reviewed. Out of that number, 25 patients were identified with unusual presentation of an acute scrotum (14 patients who presented with abdominal pain only, and 11 who presented with testicular torsion in the inguinal canal).
Results: The median age of all children… More >

Abstract The ring artifacts introduced by the defective pixels with non-linear responses in the high-resolution detector, have a great impact on subsequent processing and quantitative analysis of the reconstructed images. In this paper, a multistep method is proposed to suppress the ring artifacts of micro CT images, which firstly locates the positions of the defective pixels in the sinogram, and then corrects the corresponding value in the projections. Since the defective pixels always appear as vertical stripes in the sinogram, a horizontal curve is derived by summing the pixel values along vertical direction, thus the abrupt… More >

Abstract Image restoration is an image processing technology with great practical value in the field of computer vision. It is a computer technology that estimates the image information of the damaged area according to the residual image information of the damaged image and carries out automatic repair. This article firstly classify and summarize image restoration algorithms, and describe recent advances in the research respectively from three aspects including image restoration based on partial differential equation, based on the texture of image restoration and based on deep learning, then make the brief analysis of digital image restoration More >

Abstract Introduction: To evaluate the efficacy and safety of intraprostatic injections of onabotulinumtoxinA (onaBoNT-A) to treat refractory chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).
Materials and methods: Prospective two-group controlled study. Treatment group included adult men with refractory category-III nonbacterial CP/CPPS who underwent transurethral intraprostatic injections of onaBoNT-A (200 U). Control group included comparable patients who underwent cystoscopy only. Primary outcome was the proportion of 6-point responders (≥ 6 points reduction of total score of National Institutes of Health-Chronic Prostatitis Symptom Index [NIH-CPSI]) at 3 months. Secondary outcomes included proportions of quality of life (QoL) responders (≤ 2 points… More >

Abstract Introduction: Multimodal analgesia is an effective strategy for managing postoperative pain and reducing opioid dependence. The quadratus lumborum block (QLB) and paravertebral block (PVB) are two regional anesthesia techniques that enhance multimodal pain management. In this study, we aimed to compare the efficacy of these two approaches in patients undergoing radical cystectomy. Materials and methods: A retrospective review was conducted on patients who underwent radical cystectomy between 2014 and 2016. Patients were divided into two groups based on the type of regional anesthesia received: bilateral continuous paravertebral blocks (n = 125) or bilateral single-shot quadratus lumborum blocks… More >

Abstract Introduction: The UPOINT phenotyping system has proven effective in classifying patients with urologic pelvic pain syndromes in a clinically meaningful way and guiding multimodal therapy. While highly successful in men with chronic prostatitis/chronic pelvic pain syndrome (CPPS), its utility is more limited in patients with interstitial cystitis/painful bladder syndrome (IC/PBS). This is because all IC/PBS patients, by definition, exhibit urinary and organ-specific symptoms. Furthermore, the AUA guidelines recommend a sequential tiered approach to treatment rather than the concurrent multimodal strategy used in UPOINT. Therefore, we aimed to modify the UPOINT system to make it more practical… More >

Abstract Introduction: Stent placement is a common procedure for addressing obstructive uropathy. However, lack of operating room (OR) availability can substantially delay this procedure. In this study, we sought to assess the feasibility, safety, and efficacy of this procedure in a clinical setting using nitrous oxide (N₂O) and local anesthesia.
Materials and methods: Patients included in this study included those who were determined to need management of urinary obstruction with a JJ (“double J”) stent and had their procedure performed in the clinic procedure suite with N₂O anesthesia.
Results: We present a case series of 565 patients undergoing ureteral stent… More >
