Malignant Eccrine Adenoma With Sarcomatous (Heterologous) Components: Report Of A Rare Skin Adnexal Neoplasm With Literature Review, Hira Ishtiaq, Muhammad Abdulwaasey, Muhammad Usman Tariq, Saira Fatima

Department of Pathology and Laboratory Medicine

Malignant eccrine spiradenoma (MES) is an exceedingly rare skin adnexal tumor that arises from pre-existing benign eccrine spiradenoma (BES). MES tumors show a wide spectrum of morphological features, posing a diagnostic challenge to the pathologist. Sarcomatous (heterologous) elements are seen in a few of these tumors, further complicating the morphological picture. We herein describe a case of a 66-year-old male who presented with a recently enlarging, ulcerated, nodular skin lesion over the right leg that had been present for the last 25 years. The patient underwent wide local excision of the tumor. Microscopic examination revealed a neoplastic lesion comprising benign …

Immature Platelet Dynamics In Immune-Mediated Thrombocytopenic States, Hollie M. Reeves, Robert W. Maitta Dec 2020

Immature Platelet Dynamics In Immune-Mediated Thrombocytopenic States, Hollie M. Reeves, Robert W. Maitta

Faculty Scholarship

A major challenge encountered by clinicians is differentiating presentations characterized by significant thrombocytopenia due to overlapping clinical symptoms and signs in the setting of ambiguous laboratory results. Immature platelets represent the youngest platelets that can be measured in peripheral blood by current hematology analyzers. These young platelets are larger, with higher RNA content recently released from the bone marrow. Thrombocytopenic presentations caused directly or indirectly by immune responses can lead to compensatory bone marrow responses seeking to normalize the platelet count; thus obtaining absolute immature platelet counts may be informative while triaging patients. Over the last decade, their use has …

Community Health Sciences

Background: Socioeconomic status (SES) is an important determinant of health globally and an important explanatory variable to assess causality in epidemiological research. The 10th Sustainable Development Goal is to reduce disparities in SES that impact health outcomes globally. It is easier to study SES in high-income countries because household income is representative of the SES. However, it is well recognized that income is poorly reported in low- and middle- income countries (LMIC) and is an unreliable indicator of SES. Therefore, there is a need for a robust index that will help to discriminate the SES of rural households in a …

Bhargav, Vanessa Thorsten, Ana Garces, Robert L. Goldenberg, Shivaprasad S. Goudar, Sarah Saleem, Fabian Esamai

Community Health Sciences

Background: Preterm birth continues to be a major public health problem contributing to 75% of the neonatal mortality worldwide. Low birth weight (LBW) is an important but imperfect surrogate for prematurity when accurate assessment of gestational age is not possible. While there is overlap between preterm birth and LBW newborns, those that are both premature and LBW are at the highest risk of adverse neonatal outcomes. Understanding the epidemiology of preterm birth and LBW is important for prevention and improved care for at risk newborns, but in many countries, data are sparse and incomplete.
Methods: We conducted data analyses using …

Department of Emergency Medicine Faculty Papers

In response to pathological stimuli, the heart develops ventricular hypertrophy that progressively decompensates and leads to heart failure. miRNAs are increasingly recognized as pathogenic factors, clinically relevant biomarkers, and potential therapeutic targets. We identified that mir15a/mir16-1 cluster was negatively correlated with hypertrophic severity in patients with hypertrophic cardiomyopathy. The mir15a/mir16-1 expression was enriched in cardiomyocytes (CMs), decreased in hypertrophic human hearts, and decreased in mouse hearts after transverse aortic constriction (TAC). CM-specific mir15a/mir16-1 knockout promoted cardiac hypertrophy and dysfunction after TAC. CCAAT/enhancer binding protein (C/EBP)β was responsible for the downregulation of mir15a/mir16-1 cluster transcription. Mechanistically, mir15a/mir16-1 cluster attenuated the insulin/IGF1 …

Pd1 Inhibitor Induced Inverse Lichenoid Eruption: A Case Series, Mansha Sethi, Vaibhav Garg, Jason Lee, Sherry Yang

Department of Dermatology and Cutaneous Biology Faculty Papers

The increased use of monoclonal antibodies that target the immune checkpoint T cell receptor programmed death-1 (PD1) to treat numerous solid tumors has led to several reports describing associated cutaneous adverse events. Although lichenoid reactions have been well described, we propose that PD1 inhibitor-induced inverse lichenoid eruption (PILE) is a distinct variant. We describe two patients who presented with nearly identical deeply erythematous, malodorous, eroded anogenital plaques with focal crusting. Diagnosis of PILE was established given the biopsy findings and temporal association with PD1 inhibitor therapy. Treatment with clobetasol ointment was successful without necessitating discontinuation of immunotherapy. The findings were …

Accuracy Of Psychiatrists' Assessment Of Medication Adherence In An Outpatient Setting., Katherine B. Martin Md Dec 2020

Accuracy Of Psychiatrists' Assessment Of Medication Adherence In An Outpatient Setting., Katherine B. Martin Md

Department of Psychiatry

BACKGROUND: Many patients have uncontrolled psychiatric symptoms because they are not taking their medication as prescribed. Psychiatrists may have difficulty accurately assessing medication adherence, which is important because it helps guide them in how they prescribe. If nonadherence is the cause of uncontrolled symptoms, then strategies to improve adherence are advised. However, if nonadherence is not the cause, then the usual course of action would be to intensify or modify the medication regimen. Knowing whether nonadherence is a factor at the time of an appointment could help guide clinical decision making in real-time.

METHODS: A cohort of established patients in …
