Section of Gastroenterology

Background: Artificial Intelligence (AI) holds considerable promise for diagnostics in the field of gastroenterology. This systematic review and meta-analysis aims to assess the diagnostic accuracy of AI models compared with the gold standard of experts and histopathology for the diagnosis of various gastrointestinal (GI) luminal pathologies including polyps, neoplasms, and inflammatory bowel disease.
Methods: We searched PubMed, CINAHL, Wiley Cochrane Library, and Web of Science electronic databases to identify studies assessing the diagnostic performance of AI models for GI luminal pathologies. We extracted binary diagnostic accuracy data and constructed contingency tables to derive the outcomes of interest: sensitivity and specificity. …

Incidence Of Typhoid And Paratyphoid Fever In Bangladesh, Nepal, And Pakistan: Results Of The Surveillance For Enteric Fever In Asia Project, Mohammad Tahir Yousafzai, Sadia Shakoor, Irum Fatima Dehraj, Junaid Mehmood, Rozina Thobani, Aneeta Hotwani, Najeeb Rehman, Seema Irfan, Abdul Momin Kazi, Mohammed J. Hunzai

Department of Paediatrics and Child Health

Background: Precise enteric fever disease burden data are needed to inform prevention and control measures, including the use of newly available typhoid vaccines. We established the Surveillance for Enteric Fever in Asia Project (SEAP) to inform these strategies.
Methods: From September, 2016, to September, 2019, we conducted prospective clinical surveillance for Salmonella enterica serotype Typhi (S Typhi) and Paratyphi (S Paratyphi) A, B, and C at health facilities in predetermined catchment areas in Dhaka, Bangladesh; Kathmandu and Kavrepalanchok, Nepal; and Karachi, Pakistan. Patients eligible for inclusion were outpatients with 3 or more consecutive days of fever in the last 7 …

The Role Of Aryl Hydrocarbon Receptor (Ahr) Signaling Pathway In Oral Squamous Cell Carcinoma (Oscc): Preliminary Results., Renee Lee, Cui Xu, Leticia Ferreira, Ana Carolina Morandini, Erivan Ramos-Junior

Excellence Day

OBJECTIVES: A large number of experimental and clinical studies suggest that the origin of oral squamous cell carcinoma (OSCC) is linked to environmental carcinogenesis (tobacco, alcohol). Among these environmental factors, cigarette smoking is the most studied and has been associated with increased susceptibility to OSCC by activating signaling pathways responsible for cancer initiation and progression. Besides nicotine, cigarette smoke also contains aryl hydrocarbon receptor (AhR) agonists, such as dioxin and benzo(a)pyrene. Aberrant AhR expression and AhR pathway activation are involved in several types of cancer. However, the relationship between AhR pathway activation and oral cancer progression is still unclear.

Superior Mesenteric Artery Syndrome In An 18-Year Old Female: Case Report, Karishma Lal, Akash Khetpal, Muhammad Saad Ali Mallick, Ansab Godil, Arsalan Majeed Adam, Zahid Ali Memon

Medical College Documents

We report an unusual case of an 18-year old woman, who presented to Civil Hospital Karachi in May 2016 with complaints of vomiting, abdominal pain, dysphagia, altered bowel habits, loss of appetite and chronic weight loss. On examination, abdomen was found to be soft and non-tender with discomfort on breathing. CT angiogram revealed reduction of aortomesenteric angle and aortomesenteric distance which were both consistent with superior mesenteric artery syndrome. Reduction in angle was thought to be because of weight loss and adipose tissue depletion so patient was started on enteral and parenteral nutritional supplements. Upon seeing little to no improvement, …

Kallikrein-Related Peptidases Are Dysregulated In Pleomorphic Adenoma, Matthew D. Morrison

Electronic Thesis and Dissertation Repository

Objectives: Pleomorphic adenoma (PA) is the most common benign salivary gland tumor. Kallikrein-related peptidases (KLKs) have been identified as biomarkers in many human tumors and may influence tumor behavior. We investigated KLK1-15 messenger ribonucleic acid (mRNA) and proteins in PA specimens to determine a KLK expression profile for this tumor.

Methods: Fresh frozen PA tissue specimens (n = 26) and matched controls were subjected to RT-qPCR to detect KLK1-15 mRNA. Expression of KLK1, KLK12, KLK13 and KLK8 proteins were then evaluated via immunostaining techniques. Statistical analyses were performed with the level of significance set at P < .05.

Results: We observed downregulation …

PCOM Physician Assistant Studies Student Scholarship

OBJECTIVE: The objective of this selective EBM review is to determine whether or not laser therapy is effective at relieving pain in adult patients with recurrent aphthous stomatitis.

STUDY DESIGN: Systematic review of three randomized controlled trials published in 2009, 2009, and 2013.

DATA SOURCES: Three randomized controlled trials were obtained using PubMed.

OUTCOMES MEASURED: The symptom of pain was measured for improvement by patient survey of visual analog pain scales.

RESULTS: Prasad et al. (2013), Tezel et al. (2009), and Zand et al. (2009) all demonstrated improvement in a majority of the subjects’ pain relief from treatment with laser …

Pemphigus, Frank A. Santoro, Eric T. Stoopler, Victoria P. Werth

Departmental Papers (Dental)

Pemphigus vulgaris and paraneoplastic pemphigus are two subtypes of pemphigus that involve the oral mucosa. These autoimmune blistering disorders have antibodies targeted against proteins of keratinocyte adhesion, thereby causing acantholysis. Clinical findings include oral erosions and flaccid cutaneous bullae and erosions. In addition to the clinical exam, diagnostic tests including tissue biopsy, direct and indirect immunofluorescence, and enzyme-linked immunosorbent assays (ELISA) help to establish a diagnosis. Further malignancy workup in patients with suspected paraneoplastic pemphigus is warranted. Retrospective uncontrolled studies suggest that immunosuppressive agents reduce mortality in pemphigus vulgaris and cohort uncontrolled studies of rituximab, a monoclonal antibody against CD20, …
