Prostate cancer represents the leading malignant tumor in men over 50 years of age with 400,000 new cases being diagnosed yearly in Europe. Even if the incidence rate is higher than the mortality rate, still there is an increasing trend when speaking of its mortality. The increasing incidence of the metabolic syndrome, the unhealthy lifestyle, the high lipid and Calcium intake, the high spread of infections with Human Papilloma Virus, Human Herpes Virus, the excess of androgen consumption and the longer life expectancy, are few of the main causes of prostate cancer increasing incidence. The new systemic therapies such ...

Journal of Mind and Medical Sciences
Urinary incontinence (UI) is a common condition among women. Approximately 50% of them had an involuntary loss of urine at least once in their lifetime. It can be present during sexual activity, contributing to sexual dysfunction and often associated with anxiety or even depression, thus having a negative impact on the quality of life. The incidence of UI is related to the existence of predisposing factors. The best known are: age, weight, family history, race/ ethnicity, number of pregnancies and mode of birth, history of genitourinary interventions and factors related to ordinary habits: smoking, caffeine consumption, oral contraceptives. Studies on ...

Results: A total of 121 patients were included. At presentation, the mean prostate size was 35.7±12.2 grams and ...25%>
Factors Influencing General Surgeons To Involve Urologists In Bladder Trauma Management, 2021 Thomas Jefferson University
Factors Influencing General Surgeons To Involve Urologists In Bladder Trauma Management, Joseph Schultz, Paul Chung, Md
Introduction: Bladder trauma injuries, which are graded by severity, often require immediate care and surgical management by General Surgeons (GS) or Urologists. This study seeks to understand the inconsistencies that exist in collaboration between GS and Urologists in bladder trauma management. We hypothesize that the decision for GS to involve Urologists in bladder trauma management is a multifactorial decision with severity of bladder trauma being the primary determining factor as opposed to other factors like provider experience or hospital setting.
Methods: This cross-sectional descriptive study surveyed GS to determine how likely they were to involve Urologists in bladder trauma management ...

Bladder and bowel dysfunction (BBD) is a common yet underdiagnosed paediatric entity that describes lower urinary tract symptoms (LUTS) accompanied by abnormal bowel patterns manifested as constipation and/or encopresis. LUTS usually manifest as urgency, urinary frequency, incontinence, and urinary tract infections (UTI). Despite increasing recognition of BBD as a risk factor for long-term urinary tract problems including recurrent UTI, vesicoureteral reflux, and renal scarring, the mechanisms underlying BBD have been unclear, and treatment remains empirical. We investigated how constipation affects the lower urinary tract function using a juvenile murine model of functional constipation. Following four days of functional constipation ...

Simulation Based Team Training In Surgery - A Review, Syed Muhammad Nazim, Qamar Riaz
Section of Urology
The healthcare environment in surgery is complex, dynamic and often ambiguous. Besides subject knowledge and technical skills, other competencies, such as team work, communication skills and situation awareness, are required to ensure better patient-related outcome. Teams that demonstrate poor non-technical skills make more technical errors, often resulting in patient morbidity or mortality. Different hospital-based locations, such as operating rooms, intensive care units, emergency rooms and surgical wards, are the areas where poor team dynamics prevail. Simulation-based team training is a strategy to provide inter-professional training and experiential learning opportunities for surgeons, anaesthetists and allied health professionals. It helps them to ...

The apprenticeship model has been used for long in surgical training. It initially provides opportunity to the trainee to observe the attending surgeon, followed by gradual introduction to surgical technique under direct supervision and later with detached supervision. The attending provides informal feedback at different intervals to the trainee. Several changes have been made in postgraduate programmes with a shift towards using workplace-based assessment tools for formative and summative evaluation of the trainee's clinical skills.

Purpose: Indocyanine Green (ICG) near-infrared (NIR) fluorescence angiography is used in assessing testicular perfusion after reduction of testicular torsion to assess tissue viability.
Introduction: Determination of viability of a testicle after reduction of a testicular torsion has been performed by numerous methods including visual assessment, Doppler ultrasound, and cutting the testicular capsule. Each of these has limitations, are not always reproducible, and may involve damage to the testicle and confusion of capsular blood flow for internal perfusion. A possible alternative to these methods is the use of ICG-NIR fluorescence angiography. ICG was FDA-approved in 1959 and has been in use ...

The Effect Of Mtor Inhibitor Rapamycin On A Dietary Drosophila Melanogaster Model Of Calcium Oxalate Nephrolithiasis, Michael T. Pignanelli
Electronic Thesis and Dissertation Repository
Impaired cellular tolerance of reactive oxygen species (ROS) has been suggested as a common mechanistic link associated with aging in both metabolic syndrome and nephrolithiasis. The mechanistic (mammalian) target of rapamycin (mTOR) activity is characteristic of metabolic syndrome. When nutrients are abundant, mTOR is active. Conversely, fasting inhibits mTOR. Metabolic syndrome is correlated with an increased risk of self-reported or imaging findings of nephrolithiasis. At the individual level, patients with a higher BMI have an increased prevalence of recurrent symptomatic nephrolithiasis, 24-hour urinary excretion of oxalate, sodium, uric acid, calcium, and phosphorous as well as lower pH. Calcium oxalate crystals ...

Urinary bladder cancer (UBC) is the most common malignancy of the urinary tract in humans, with an estimated global prevalence of 1.1 million cases over 5 years. Due to high rates of recurrence and resistance to chemotherapy, UBC is one of the most expensive cancers to treat, resulting in significant health care costs. There is, therefore, a critical need to develop innovative molecular and cellular tools to refine patient stratification and help predict response to treatment. Urine is an underused resource of biological components shed from bladder tumors, such as exfoliated cells and extracellular vesicles, that could serve as ...

Paroxysmal Nocturnal Hemoglobinuria: Pandora’S Box?, Mihnea Alexandru Găman, Iulia Ursuleac, Daniel Coriu
Journal of Mind and Medical Sciences
Introduction. Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired non-malignant hematological disorder which affects the pluripotent hematopoietic stem cell. The cause of PNH development is the occurrence of somatic mutations in the phosphatidylinositol glycan-A gene which encodes a protein necessary for the biosynthesis of glycosylphosphatidylinositol anchors. The diagnosis of PNH requires the presence of signs of intravascular hemolysis, thrombosis, and (or) bone marrow failure. Case Report. We report the case of a 42-year-old female, diagnosed with PNH at the age of 27, whose evolution was initially characterized predominantly by hemolytic attacks and whose disease pattern evolved towards thromboembolic episodes with the ...
