Acute Presentation Of Cocoon Abdomen As Septic Peritonitis Mimicking With Strangulated Internal Herniation: A Case Report, Sabah Uddin Saqib, Rimsha Farooq, Omair Saleem, Sarosh Moeen, Tabish Umer Chawla 2021 Aga Khan University

Acute Presentation Of Cocoon Abdomen As Septic Peritonitis Mimicking With Strangulated Internal Herniation: A Case Report, Sabah Uddin Saqib, Rimsha Farooq, Omair Saleem, Sarosh Moeen, Tabish Umer Chawla

Section of General Surgery

Background: Abdominal cocoon syndrome is a rare cause of intestinal obstruction in which loops of small bowel get entrapped inside a fibro-collagenous membrane. Condition is also known in the literature as sclerosing peritonitis and in the majority of cases, it has no known cause. Although the majority of patients exhibit long-standing signs and symptoms of partial bowel obstruction in an out-patient clinic, its acute presentation in the emergency room with features of sepsis is extremely rare. This case report aims to describe the emergency presentation of cocoon abdomen with septic peritonitis.
Case presentation: A 35-year-old male with no known co-morbidity ...

Non-Invasive Predictors Of Response To Tamsulosin For Benign Prostatic Obstruction, Mohammad Shoaib, Muhibullah Bangash, Wajahat Aziz, M Hammad Ather

Section of Urology

Objectives: To identify non-invasive predictors of response to tamsulosin 0.4 mg in patients with benign prostatic obstruction (BPO).
Methods: Males ≥ 50 years of age with lower urinary tract symptoms (LUTS) suggestive of BPO for over three months were included in the study. We assessed change in the mean International Prostate Symptom Score (IPSS) and maximum flow rate (Qmax) after six weeks of medical therapy. Clinical and uroflowmetry parameters were compared between two groups of patients with >25% vs. <25% change in the IPSS after treatment. Pre- and post-treatment post-void residue (PVR), Qmax, and IPSS were compared by independent t-test, univariate/multivariate regression analysis.
Results: A total of 121 patients were included. At presentation, the mean prostate size was 35.7±12.2 grams and ...

Predicting The 10-Year Risk Of Death From Other Causes In Men With Localized Prostate Cancer Using Patient-Reported Factors: Development Of A Tool, Daniel M. Frendl, Gordon A. Fitzgerald, Mara M. Epstein, Jeroan J. Allison, Mitchell H. Sokoloff, John E. Ware Jr.

Open Access Publications by UMMS Authors

OBJECTIVE: To develop a tool for estimating the 10-year risk of death from other causes in men with localized prostate cancer.

SUBJECTS AND METHODS: We identified 2,425 patients from the Surveillance Epidemiology and End Results-Medicare Health Outcomes Survey database, age < 80, newly diagnosed with clinical stage T1-T3a prostate cancer from 1/1/1998-12/31/2009, with follow-up through 2/28/2013. We developed a Fine and Gray competing-risks model for 10-year other cause mortality considering age, patient-reported comorbid medical conditions, component scores and items of the SF-36 Health Survey, activities of daily living, and sociodemographic characteristics. Model discrimination and calibration were compared to predictions from Social Security life table mortality risk estimates.

RESULTS: Over a median follow-up of 7.7 years, 76 men died of prostate-specific causes and 465 died of other causes. The strongest predictors of 10-year other cause mortality risk included increasing age at diagnosis, higher approximated Charlson Comorbidity Index score, worse patient-reported general health (fair or poor vs. excellent-good), smoking at diagnosis, and marital status (all other vs ...


Epigenetic Regulation Of Prostate Cancer, Ruixin Wang, Xiaoqi Liu 2020 University of Kentucky

Epigenetic Regulation Of Prostate Cancer, Ruixin Wang, Xiaoqi Liu

Toxicology and Cancer Biology Faculty Publications

Prostate cancer is (PCa) the second leading cause of cancer death in males in the United State, with 174,650 new cases and 31,620 deaths estimated in 2019. It has been documented that epigenetic deregulation such as histone modification and DNA methylation contributes to PCa initiation and progression. EZH2 (enhancer of zeste homolog 2), the catalytic subunit of the Polycomb Repressive Complex (PRC2) responsible for H3K27me3 and gene repression, has been identified as a promising target in PCa. In addition, overexpression of other epigenetic regulators such as DNA methyltransferases (DNMT) is also observed in PCa. These epigenetic regulators undergo ...


The Effect Of Mtor Inhibitor Rapamycin On A Dietary Drosophila Melanogaster Model Of Calcium Oxalate Nephrolithiasis, Michael T. Pignanelli 2020 The University of Western Ontario

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 ...

Effect Of Hyperprolactinemia On Male Fertility, Ghazi Tadmori, Najwa Fakhal, Marwan Halabi

Al Jinan الجنان

This study aims at the investigation of the effect of prolactinemia on male fertility. The study group included 30 males with infertility problems and accompanied with high prolactin hormone levels in the blood. Hormone and seminal fluid analyses were performed before and after treatments with Cabergoline (DostinexTM), and results were comparable to those observed in a control group consisting of 14 healthy males. Results have shown that the increase in prolactin levels led to flaws in sexual hormone concentrations and to a decrease in sperm count and mobility compared to the control group. For this purpose, two groups were tested ...

Implantation And Gastrulation Abnormalities Characterize Early Embryonic Lethal Mouse Lines [Preprint], Yeonsoo Yoon, Joy Riley, Judith Gallant, Ping Xu, Jaime A. Rivera-Pérez

University of Massachusetts Medical School Faculty Publications

The period of development between the zygote and embryonic day 9.5 in mice includes multiple developmental milestones essential for embryogenesis. The preeminence of this period of development has been illustrated in loss of function studies conducted by the International Mouse Phenotyping Consortium (IMPC) which have shown that close to one third of all mouse genes are essential for survival to weaning age and a significant number of mutations cause embryo lethality before E9.5. Here we report a systematic analysis of 21 pre-E9.5 lethal lines generated by the IMPC. Analysis of pre- and post-implantation embryos revealed that the ...

The Impact Of Ethnicity And Immigration On Prostate Cancer Mortality In Canada, Noah Stern 2020 The University of Western Ontario

The Impact Of Ethnicity And Immigration On Prostate Cancer Mortality In Canada, Noah Stern

Electronic Thesis and Dissertation Repository

Despite the prevalence of prostate cancer its pathogenesis remains unclear. Marked differences in mortality rates have been observed between countries, however, it is unclear whether the source of the observed differences is driven by underlying genetics, geographic, or social factors. This thesis investigated the impact of ethnicity and immigration on prostate cancer mortality in Canada using the Canadian Census Health and Environment Cohort. South Asian and East Asian men were seen to be at decreased risk of prostate cancer mortality, while no increased risk was observed in black men. These results affirm studies showing lower risks in Asian men; however ...

Medical Student Research Symposium

INTRODUCTION AND OBJECTIVE: Ductal adenocarcinoma is considered a rare histological variant of prostate adenocarcinoma (PCa). Given the rarity of this subtype, optimal treatment strategies for men with nonmetastatic ductal PCa is largely unknown. We aimed to describe the impact of surgery, radiotherapy, and systemic therapy on overall survival (OS) in men with nonmetastatic ductal PCa.

METHODS: We retrospectively selected 2209 cases of ductal PCa, diagnosed between 2004 and 2015, within the National Cancer Database (NCDB). Exclusion of metastatic patients yielded a total sample of 1993 individuals. Cox regression analysis tested the impact of treatment (surgery, radiotherapy, systemic therapy and no ...

INTRODUCTION: End-stage kidney disease (ESKD) is a major public health problem affecting more than 2 million people worldwide. It is one of the most severe chronic non-communicable diseases. Haemodialysis (HD) is the most common therapeutic option but is also associated with a risk of cardiovascular events, hospitalisation and suboptimal quality of life. Over the past decades, haemodiafiltration (HDF) has become available. Although high-dose HDF has shown some promising survival advantage compared to conventional HD, the evidence remains controversial. A Cochrane systematic review found, in low-quality trials, with various convective forms of dialysis, a reduction in cardiovascular, but not all-cause mortality ...

Sexual Dysfunction In Men After High Energy Pelvic Fractures: Narrative Review Of Targeted Literature, Obada Hussein Hasan, Muhammad Atif, Naveed Baloch, Imran K. Jalbani, Masood Umer

Section of Orthopaedic Surgery

Pelvic fractures represents high energy trauma with associated other organ injuries including intra-abdominal injuries, haemorrhage and extremity injuries. Anatomical location of genitourinary structures makes them vulnerable to injury with pelvic fracture. Incidence of sexual dysfunction varies in literature with 5% incidence of dysfunction in patients without urethral injury and 42% with urethral injuries. Hence in pelvic fracture, erectile dysfunction may be due to neurogenic, vascular, corporal and psychogenic injury. In this narrative review of targeted English literature from all level of evidences, which is written and supervised by experienced specialized orthopaedic, trauma and urology surgeons who were among the pioneers ...

Recurrent urinary tract infections (UTIs) pose a significant burden on the health care system. Underlying mechanisms predisposing children to UTIs and associated changes in the urinary proteome are not well understood. We aimed to investigate the urinary proteome of a subset of children who have vesicoureteral reflux (VUR) and recurrent UTIs because of their risk of developing infection-related renal damage. Improving diagnostic modalities to identify UTI risk factors would significantly alter the clinical management of children with VUR. We profiled the urinary proteomes of 22 VUR patients with low grade VUR (1-3 out of 5), a history of recurrent UTIs ...
