Gastrointestinal Bleeding As Initial Manifestation Of Injection Drug Use-Associated Amyloidosis, Mohammed Rifat Shaik, Nishat Anjum Shaikh, Elvina Yunasan, Erika Wheeler, Robert T Chow May 2023

Gastrointestinal Bleeding As Initial Manifestation Of Injection Drug Use-Associated Amyloidosis, Mohammed Rifat Shaik, Nishat Anjum Shaikh, Elvina Yunasan, Erika Wheeler, Robert T Chow

Journal of Community Hospital Internal Medicine Perspectives

Systemic amyloidosis has been reported in the context of injection drug use, usually related to ongoing chronic inflammation and persistent cutaneous infections. The kidneys are almost always the first organs affected in that setting. Involvement of the gastrointestinal tract is less common and rarely the initial site of presentation. We present a case of systemic amyloidosis that primarily manifested in the gastrointestinal tract, occurring in the setting of chronic injection drug use. The patient's hemoglobin level dropped progressively over time due to ongoing, slow gastrointestinal bleeding, prompting an endoscopic examination that ultimately confirmed the presence of gastrointestinal amyloidosis. As the …


Recurrent Psychosis In Non-Celiac Gluten Sensitivity, Scarlet Louis-Jean, Shire Chaudhry May 2023

Recurrent Psychosis In Non-Celiac Gluten Sensitivity, Scarlet Louis-Jean, Shire Chaudhry

Journal of Community Hospital Internal Medicine Perspectives

Neuropsychological manifestations following food exposures in patients with food sensitivities are increasingly being identified in the literature, as understanding of the gut-brain axis is further improved. Non-celiac gluten sensitivity (NCGS) has been shown to occur in individuals without serological or biopsied evidence of celiac disease (CD), who manifest psychotic or mood disorders that resolve following elimination of gluten. In this case history, we discuss a similar manifestation in a 31-year-old woman without serological evidence of CD, whose psychiatric symptoms improve with gluten elimination.

Confidence-Based Laboratory Test Reduction Recommendation Algorithm, Tongtong Huang, Linda T Li, Elmer V Bernstam, Xiaoqian Jiang

Faculty, Staff and Student Publications

BACKGROUND: We propose a new deep learning model to identify unnecessary hemoglobin (Hgb) tests for patients admitted to the hospital, which can help reduce health risks and healthcare costs.

METHODS: We collected internal patient data from a teaching hospital in Houston and external patient data from the MIMIC III database. The study used a conservative definition of unnecessary laboratory tests, which was defined as stable (i.e., stability) and below the lower normal bound (i.e., normality). Considering that machine learning models may yield less reliable results when trained on noisy inputs containing low-quality information, we estimated prediction confidence to assess the …

BACKGROUND: Recessive Dystrophic Epidermolysis Bullosa (RDEB) is a rare inherited skin disease caused by variants in the COL7A1 gene, coding for type VII collagen (C7), an important component of anchoring fibrils in the basement membrane of the epidermis. RDEB patients suffer from skin fragility starting with blister formation and evolving into chronic wounds, inflammation and skin fibrosis, with a high risk of developing aggressive skin carcinomas. Restricted therapeutic options are limited by the lack of in vitro models of defective wound healing in RDEB patients.

RESULTS: In order to explore a more efficient, non-invasive in vitro model for RDEB studies, …

We report a case of a patient with newly diagnosed, locally extensive and cystic, suprasellar papillary craniopharyngioma successfully treated with single-agent Dabrafenib. The patient was symptomatic with gait imbalance with falls, lethargic episodes, fatigue and incontinence. Diagnostic imaging demonstrated a cystic suprasellar tumor extending into the third ventricle causing obstructive hydrocephalus. The tumor was partially debulked, and bilateral shunts were placed. NGS sequencing demonstrated BRAF V600E mutation, and the patient was prescribed dual agent Dabrafenib and Trametinib. However, due to insurance denial for Trametinib, he only received single-agent Dabrafenib (150mg BID). The treatment resulted in a major response (over two …

The molecular and functional contributions of intratumoral nerves to disease remain largely unknown. We localized synaptic markers within tumors suggesting that these nerves form functional connections. Consistent with this, electrophysiological analysis shows that malignancies harbor significantly higher electrical activity than benign disease or normal tissues. We also demonstrate pharmacologic silencing of tumoral electrical activity. Tumors implanted in transgenic animals lacking nociceptor neurons show reduced electrical activity. These data suggest that intratumoral nerves remain functional at the tumor bed. Immunohistochemical staining demonstrates the presence of the neuropeptide, Substance P (SP), within the tumor space. We show that tumor cells express the …

Checkpoint immunotherapy has yielded meaningful responses across many cancers but has shown modest efficacy in advanced prostate cancer. B7 homolog 3 protein (B7-H3/CD276) is an immune checkpoint molecule and has emerged as a promising therapeutic target. However, much remains to be understood regarding B7-H3's role in cancer progression, predictive biomarkers for B7-H3-targeted therapy, and combinatorial strategies. Our multi-omics analyses identified B7-H3 as one of the most abundant immune checkpoints in prostate tumors containing PTEN and TP53 genetic inactivation. Here, we sought in vivo genetic evidence for, and mechanistic understanding of, the role of B7-H3 in PTEN/TP53-deficient prostate …

Colonic Stenosis In An Elderly Female, Tiffany R. Pittman, Kylie A. Parrish, Grace M. Perry, Oyindamola C. Orekoya, Shiv Dhiman, Savita Arya

Research Day

Introduction

Colonic stenosis is commonly caused by chronic inflammation and is a known side effect of inflammatory conditions, such as diverticulitis and irritable bowel syndrome. Diverticulosis is a common condition where parts of the colon wall become weakened, forming outpouches. These outpouchings may become inflamed, leading to diverticulitis. This chronic inflammation can cause scarring and fibrosis of the colon, resulting in colonic stenosis. Inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis, may also result in scarring and colonic stenosis. The incidence rate of patients developing colonic stenosis is 8-13.5% for Crohn's disease and 1-11% for ulcerative colitis. Patients …

Research Day

Advanced cancers are typically resistant to treatment, which leads to most experimental cancer immunotherapy approaches being tested against smaller tumors. In this study, we show that even late-stage, weakly immunogenic mouse B78 melanomas, with tumor volumes of 1500-2000 mm3, can be eradicated by a combined radio-immunotherapy regimen (CRIR) which includes local radiotherapy, intratumoral interleukin 12, slow-release systemic interleukin 2 and checkpoint blockade with anti-CTLA-4 antibody. Flow analysis of the tumors revealed a reduction in T regulatory (Treg) cells and an increase in CD8/Treg ratios following CRIR. T cell depletion did not prevent the rapid shrinkage of treated tumors, but suppressed …

Introduction

Hyperostosis frontalis interna (HFI) is a condition that causes a benign thickening of the frontal bone. Many studies in the past have correlated sex with the incidence of HFI. Additionally, females, especially those postmenopausal, seem to be the predominant group affected. The primary objective of this study is to explore incidence of HFI and how it relates to the different sexes. The secondary objective is to further investigate the correlation of HFI with liver and gonadal pathologies.

Methods

A study is designed to explore the prevalence of hyperostosis frontalis interna among sexes in a sample of cadavers (n=38) at …
