PI-RADS 3 score: A retrospective experience of clinically significant prostate cancer detection.

Rationale and objectives: The study aims to propose an optimal workflow in patients with a PI-RADS 3 (PR-3) assessment category (AC) through determining the timing and type of pathology interrogation used for the detection of clinically significant prostate cancer (csPCa) in these men based upon a 5-year retrospective review in a large academic medical center. Materials and methods: This United States Health Insurance Probability and Accountability Act (HIPAA)-compliant, institutional review board-approved retrospective study included men without prior csPCa diagnosis who received PR-3 AC on magnetic resonance (MR) imaging (MRI). Subsequent incidence and time to csPCa diagnosis and number/type of prostate interventions was recorded. Categorical data were compared using Fisher's exact test and continuous data using ANOVA omnibus F-test. Results: Our cohort of 3238 men identified 332 who received PR-3 as their highest AC on MRI, 240 (72.3%) of whom had pathology follow-up within 5 years. csPCa was detected in 76/240 (32%) and non-csPCa in 109/240 (45%) within 9.0 ± 10.6 months. Using a non-targeted trans-rectal ultrasound biopsy as the initial approach (n = 55), another diagnostic procedure was required to diagnose csPCa in 42/55 (76.4%) of men, compared with 3/21(14.3%) men with an initial MR targeted-biopsy approach (n = 21); (p < 0.0001). Those with csPCa had higher median serum prostate-specific antigen (PSA) and PSA density, and lower median prostate volume (p < 0.003) compared with non-csPCa/no PCa. Conclusion: Most patients with PR-3 AC underwent prostate pathology exams within 5 years, 32% of whom were found to have csPCa within 1 year of MRI, most often with a higher PSA density and a prior non-csPCa diagnosis. Addition of a targeted biopsy approach initially reduced the need for a second biopsy to reach a for csPCa diagnosis. Thus, a combination of systematic and targeted biopsy is advised in men with PR-3 and a co-existing abnormal PSA and PSA density.

Patients' and physicians' attitudes and perception about asthma in the Gulf: A subset analysis from the Asthma Insights and Management Survey in the Gulf and Russia.

Background: Asthma is a prevalent disorder in the Gulf region. However, available data concerning asthma control and patients' perception with regard to their disease are still insufficient. Objective: To investigate patients' perception and behavior with regard to the asthma-related burden, the level of asthma control, and asthma management in three Gulf countries. Methods: This study presented a subset analysis of the Asthma Insights and Management survey about the asthma burden and management in the Gulf region and Russia. In this subset analysis, we retrieved the data of the patients from Saudi Arabia, United Arab Emirates, and Kuwait. Results: The current survey's population was composed of 452 patients. One hundred fifty-four patients (34.1%) rated themselves as having poorly controlled asthma, whereas 60.3% of the patients perceived their asthma as completely or well controlled. However, only two patients (0.4%) had controlled asthma according to the global asthma guidelines criteria for asthma control. Most of the patients (67.7%) reported that their asthma got worse when outdoors. Almost 70% of the patients on daily control plus a quick relief regimen reported that their asthma got worse when they were outdoors. Over the past 12 months, 95 patients (21%) reported asthma exacerbation. More than half of the included patients experienced an asthma attack that stopped their activities, whereas 54.2% of the patients were forced to leave work or school due to an asthma attack, and 53.1% had to cancel an appointment or had to go to bed due to the severity of the attack. With concern to asthma management, only 30.5% of the patients were given a lung function test for the assessment of their asthma. A written action plan for asthma treatment was developed by the physician or the practice nurse for only 21.7% of the patients. Conclusion: In the Gulf region, asthma exerts a substantial burden on patients who are affected. Such a burden significantly impacted patients' quality of life.

Endoscopic Management of Post-Laparoscopic Sleeve Gastrectomy Leakage and Stenosis Using Fully Covered Stent.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed surgery to treat morbid obesity. Post-LSG leak and stenosis are serious complications that can be associated with significant morbidity and mortality. OBJECTIVE: The objective was to report the efficacy and safety profile of using specifically designed fully covered self-expandable metallic stent for the treatment of post-LSG complications. METHODS: This retrospective study included adult patients who underwent placement of a fully covered esophagogastric, self-expandable metallic stent for post-LSG leak or stenosis. The procedure was carried out at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, between September 2017 and May 2019. Data regarding demographics, indication for stenting, size of the stent, procedural success and poststenting adverse events were collected. RESULTS: A total of 14 patients met the inclusion criteria, with indication for endoscopic stenting being post-LSG leak in 11 patients and stenosis in 3 patients. The technical success rate of self-expandable metallic stent placement was 100%, and the clinical success was 85.7% (12 of 14 patients). Nausea (71.4%) and vomiting (85.7%) were the most frequent mild adverse events reported. Stent-induced esophageal stricture was the only major adverse event reported in two patients. CONCLUSION: Placement of specifically designed self-expandable metallic stent for the treatment of post-LSG leak and stenosis is an effective and safe approach. Further studies with larger cohorts are needed to assess the optimal duration needed to treat such complications.

Stromal Fibrosis of the Breast: A Spectrum of Benign to Malignant Imaging Appearances.

OBJECTIVES: The aim of this study is to demonstrate the various imaging appearances of stromal fibrosis on mammography, ultrasound, and magnetic resonance imaging (MRI). MATERIAL AND METHODS: This study included 75 female patients who presented to the American University of Beirut Medical Center between January 2010 and October 2015 for breast imaging. 66 (88%) patients obtained a mammogram, 71 (95%) had an ultrasound, and 6 (8%) had an MRI. Patients included had stromal fibrosis proven on biopsy. RESULTS: The most common finding on mammogram was calcifications which was present in 14 (21%) patients, while on ultrasound it was a mass which was present in 61 (86%) patients. A mass was detected on MRI in 2 (33.5%) patients. Most lesions detected had benign findings such as masses with circumscribed margins. We had a follow-up for 53 (71%) patients with an average follow-up interval of 28.5 months (range: 5 - 70). Increase in size of the index lesion was noted in only 2 patients; upon rebiopsy, pathology results read stromal fibrosis for one lesion and fibroadenoma for the other. The remaining lesions were either stable or decreased in size. The higher detection rate of a mass on ultrasound was statistically significant (p<0.001) in comparison to that of mammography. CONCLUSION: Stromal fibrosis can have various presentations on imaging from benign to suspicious for malignancy features. In the case of accurate targeted biopsy, when stromal fibrosis is diagnosed, the result can be considered concordant. Therefore, such lesions can be followed up by imaging to document stability and confirm benignity.

Congestive hepatopathy secondary to large renal arteriovenous malformation.

A 75-year-old woman presented with acute onset dyspnoea, and was found to have signs of pulmonary congestion on clinical examination. Imaging revealed cardiomegaly and coincident congestive hepatopathy, secondary to a left renal arteriovenous malformation. The presence of a high flow vascular shunt in the left kidney was possibly the causative factor behind both the high-output cardiac failure and congestive hepatopathy.
