Balancing The Medical, Psychiatric, And Ethical Considerations In The Inpatient Treatment Of Extreme Anorexia Nervosa: A Case Report, Carter A. Schulz, Carolyn A. Kennedy

Aesculapius Journal (Health Sciences & Medicine)

Introduction: Anorexia nervosa (AN) is a psychiatric illness characterized by restricted energy intake, intense fear of gaining weight, and a disturbance in body image. A 2011 meta-analysis estimated the mortality rate for anorexia nervosa to be over 5 times that of the general population, with one-fifth of deaths in AN patients being due to suicide. Treating this disease is notoriously difficult, and treatment is complicated by these patients’ characteristically poor insight.

Faculty, Staff and Student Publications

Growth factor receptor-bound protein 2 (GRB2) is a cytoplasmic adapter for tyrosine kinase signaling and a nuclear adapter for homology-directed-DNA repair. Here we find nuclear GRB2 protects DNA at stalled replication forks from MRE11-mediated degradation in the BRCA2 replication fork protection axis. Mechanistically, GRB2 binds and inhibits RAD51 ATPase activity to stabilize RAD51 on stalled replication forks. In GRB2-depleted cells, PARP inhibitor (PARPi) treatment releases DNA fragments from stalled forks into the cytoplasm that activate the cGAS-STING pathway to trigger pro-inflammatory cytokine production. Moreover in a syngeneic mouse metastatic ovarian cancer model, GRB2 depletion in the context of PARPi treatment …

Isoform Alterations In The Ubiquitination Machinery Impacting Gastrointestinal Malignancies, Srimathi Kasturirangan, Derek Nancarrow, Ayush Shah, Kiran Lagisetty, Theodore Lawrence, David Beer, Dipankar Ray

Department of Medicine Faculty Papers

The advancement of RNAseq and isoform-specific expression platforms has led to the understanding that isoform changes can alter molecular signaling to promote tumorigenesis. An active area in cancer research is uncovering the roles of ubiquitination on spliceosome assembly contributing to transcript diversity and expression of alternative isoforms. However, the effects of isoform changes on functionality of ubiquitination machineries (E1, E2, E3, E4, and deubiquitinating (DUB) enzymes) influencing onco- and tumor suppressor protein stabilities is currently understudied. Characterizing these changes could be instrumental in improving cancer outcomes via the identification of novel biomarkers and targetable signaling pathways. In this review, we …

A Case Report : Rosai-Dorfman Disease Of The Breast, Jenjeera Prueksadee

Chulalongkorn Medical Journal

Abstract

A case report of Rosai-Dorfman disease (sinus histiocytosis with massive lymphadenopathy) of the breast is one of the rare diseases, characterized by benign proliferative disorder of histiocyte. Most occur within lymph nodes whereas the rest involve extranodal sites. Breast involvement is considered extremely rare but considerable because of radiological findings simulating breast cancer. We report the case of a 59-year-old Thai woman who underwent screening mammography. Her biopsy resulted in abnormal histiocytes with S-100 protein expression, some of them with emperipolesis (lymphophagocytosis). Recognition of Rosai-Dorfman disease leads to correct diagnosis and further appropriate proper treatment strategy.

Primary Lung And Pleural Malignancies In Children: Imaging Of A Case Series, Teerasak Phewplung, Tanitha Phruksahirun

Chulalongkorn Medical Journal

Early diagnosis of primary lung and pleural malignancies is a challenge because it is extremely rare in children. The patient often presents with metastatic disease and non-neoplastic lesions. Clinical detection and imaging studies are nonspecific findings and may be indistinguishable from other lung malformations, resulting in a delay in diagnosis and treatment and an increase in tumor morbidity and mortality.

We present four cases of children whose clinical presentation and initial imaging had suspicious abnormalities and were eventually revealed to be primary lung and pleural malignancies. The literature on primary lung and pleural malignancies is also reviewed.

Faculty, Staff and Student Publications

Background: Chronic abdominal pain is the hallmark symptom of chronic pancreatitis (CP), with 50% to 80% of patients seeking medical attention for pain control. Although several management options are available, outcomes are often disappointing, and opioids remain a mainstay of therapy. Opioid-induced hyperalgesia is a phenomenon resulting in dose escalation, which may occur partly because of the effects of opioids on voltage-gated sodium channels associated with pain. Preclinical observations demonstrate that the combination of an opioid and the antiseizure drug lacosamide diminishes opioid-induced hyperalgesia and improves pain control.

Objective: In this phase 1 trial, we aim to determine the safety, …
