Background: Carotid artery stenting (CAS) is an interventional management in preventing ischemic stroke caused by carotid artery stenosis. After the treatment with CAS, in-stent restenosis caused by neointimal hyperplasia may develop.

Purpose: This study aims to obtain a better determination of neointimal hyperplasia using superb microvascular imaging (SMI), which provides a high-quality visualization of the endoluminal lesions, and to compare these results with B-mode and Doppler ultrasound (US).

Objective: To compare the rate of diagnosing clinically significant prostate cancer (csPCa) in men with elevated PSA stratified by baseline IsoPSA Index, thus assessing IsoPSA's intermediate-term predictive ability for csPCa.

Material And Methods: Single-center retrospective review of consecutive patients (n=1578) who underwent IsoPSA testing from November 2016-August 2022. Data dichotomized into patients with low(≤6) and high IsoPSA Indices (>6).

Article Synopsis
  • Hepatocellular carcinoma (HCC) is a rare but serious pediatric liver tumor, making up 1% of all childhood tumors, and this study reviewed cases from 2002 to 2022.
  • A total of 15 pediatric patients, mostly presenting with abdominal pain, had their medical data analyzed, revealing common diagnoses include different forms of HCC and some underlying diseases like hepatitis and metabolic disorders.
  • The study found that surgical options like liver transplantation and resection are successful, with a 75% survival rate for transplant patients, and emphasizes the benefits of a multidisciplinary treatment approach.

Objective: This study aimed to compare daily and total recreational music exposure levels and extended-spectrum audiogram results in young adults without pre-existing hearing problems.

Design: The study included healthy volunteers aged 18-25 with no known ear disease or hearing loss. Participants completed a questionnaire, underwent otoscopic and tympanometric examinations, and determined preferred music volumes in an audiometry booth using calibrated music samples of their preferred genres.

Some researchers have speculated that the prostatic microbiome is involved in the development of prostate cancer (PCa) but there is no consensus on certain microbiota in the prostatic tissue of PCa vs. healthy controls. This systematic review aims to investigate and compare the microbiome of PCa and healthy tissue to determine the microbial association with the pathogenesis of PCa.

Aim: Acquired post-transplant diaphragmatic hernia (PTDH) is a rare complication of liver transplantation (LT) in children. We aimed to present our experience in PTDH, and a possible causative background is discussed.

Methods: Medical records of patients who had undergone diaphragmatic repair following LT between 2015 and 2023 were reviewed.

Purpose: To create a reproducible and standardized urethral stricture model in rats, evaluating both histomorphologic findings and gene expression data. In studies involving experimental animals, more standardization is needed for the creation of a urethral stricture model.

Methods: Sixteen male rats were randomized into two groups.

Objective: The general approach to malignant biliary obstruction (MBO) is to provide drainage in all patients with jaundice. However, the procedure is often palliative, and its contribution to survival is debated. This study aimed to investigate prognostic factors in patients undergoing percutaneous transhepatic biliary drainage (PTBD) for MBO.

Background: Kidney stones (also called renal stones) can be a source of pain, obstruction, and infection. Depending on size, location, composition, and other patient factors, the treatment of kidney stones can involve observation, shock wave lithotripsy, retrograde intrarenal surgery (RIRS; i.e.

Objectives: To assess the effects of percutaneous nephrolithotomy (PCNL) vs retrograde intrarenal surgery (RIRS) for the treatment of renal stones in adults.

Methods: We performed a comprehensive search of the Cochrane Library, MEDLINE, Embase, three other databases, trials registries, other sources of the grey literature, and conference proceedings up to 23 March 2023. We applied no restrictions on publication language or status.

Objective: Malignant bladder neoplasms can cause life-threatening persistent hematuria. Selective transarterial embolization is an effective way to achieve hemostasis in such patients. The purpose of our study is to share our experience in these patients and to evaluate the short- and long-term effectiveness of this procedure.

Objective: Horseshoe kidney is the most common renal fusion anomaly, accounting for 90%. The study aims to explore the variations in the renal arteries of individuals with horseshoe kidney anomalies and contribute to the classification in the literature.

Materials And Methods: Computed tomography images of 145 individuals who had intravenous contrast-enhanced abdominal computed tomography for any reason and had horseshoe kidney anomalies were analyzed retrospectively, and the presence, origin, and number of accessory renal arteries were evaluated.

Background: Near-infrared autofluorescence imaging is an adjunct to parathyroid identification. As it does not show perfusion, it is important to study its impact during thyroidectomy by measuring quantifiable data on parathyroid detection rather than function. The aim of this study was to compare incidental parathyroidectomy rates in patients undergoing total thyroidectomy with or without near-infrared autofluorescence.

Background: Peyronie's disease is a condition that results in the development of penile plaques that can lead to penile curvature, pain, and erectile dysfunction, making sexual activity difficult. A number of non-surgical interventions exist to improve this condition, which include topical and injection agents as well as mechanical methods; however, their effectiveness remains uncertain. We performed this review to determine the effects of these non-surgical treatments.

Background: Staff shortage is a long-standing issue in long term care facilities (LTCFs) that worsened with the COVID-19 outbreak. Different states in the US have employed various tools to alleviate this issue in LTCFs. We describe the actions taken by the Commonwealth of Massachusetts to assist LTCFs in addressing the staff shortage issue and their outcomes.

Background: In recent years, many studies have proven that percutaneous thermal ablation is an effective second-line treatment method with low complication rates in early-stage non-small cell lung carcinoma and lung metastases. Radiofrequency ablation and microwave ablation are commonly used for this purpose.

Purpose: To evaluate the factors affecting the success of the percutaneous thermal ablation treatment with technical success, complication rates, and long-term follow-up results in metastatic lung lesions.

Objective: To compare the ability of the obturator nerve block (ONB) and increased plasma ignition distance practice (IPDP) techniques to inhibit obturator nerve reflex (ONR) occurring with bipolar transurethral resection of the bladder.

Methods: Sixty patients who had a tumor placed at the lateral sidewall or had a tumor in another part of the bladder along with the lateral wall were randomly enrolled. Cystoscopic and ultrasonographic examinations and a computerized tomography scanning of the urinary bladder were used to determine the ONB side.

Purpose: To evaluate the expansion effect of self-expandable stents during the first week after carotid artery stenting (CAS) procedure and to examine the variation of the effect according to the carotid plaque type.

Methods: Seventy stenotic carotid arteries of 69 patients were stented by using self-expanding Wallstents with diameters of 7 and 9 mm, after detection of stenosis and plaque type by Doppler ultrasonography. Post-stent aggressive ballooning was avoided and residual stenosis rates were measured with digital subtraction angiography.
