Case report: An unusual presentation of intra-abdominal desmoplastic small round cell tumor.

Background: Intra-abdominal desmoplastic small round cell tumor (IDSRCT) is a rare entity (0.2-0.74 cases per million people per year), which predominantly occurs in young men. It may present as an abdominal mass with pain, distention, and constipation. IDSRCT has a very poor prognosis, with 5-year overall survival estimated at 15%-30%. Diagnosis is made with tissue biopsy. Case description: We present a case of a 28-year-old man with a history of schizophrenia and depression who presented to an emergency room (ER) in November 2022 with constipation and pelvic pain. The patient was sent home with a bowel regimen after radiography showed no obstruction. He re-presented for evaluation due to persistent pain. A computerized tomography scan of the abdomen and pelvis (CT A/P) revealed numerous pelvic masses with severe colitis, bilateral moderate hydronephrosis, and metastatic disease in the liver. A colonoscopy showed a mass extending 3 cm from the anus to 10 cm causing a partial obstruction. Biopsy was read as squamous cell carcinoma (SCC). The patient was subsequently admitted to our institution with pelvic pain, nausea, and vomiting. Colorectal surgery performed a colectomy with end-ileostomy due to colonic obstruction. He was evaluated by a medical oncologist, with previous slides requested for review. Initial review was concerning metastatic basaloid SCC with neuroendocrine features and a Ki67 of 70%. Given his recent abdominal surgeries, chemotherapy was delayed until February 2023 when he was started on reduced dose carboplatin and paclitaxel. Tumor specimen was sent for next generation sequencing (NGS) and programmed death-1 ligand 1 (PD-L1) testing. NGS results returned after the first dose of chemotherapy was given and showed a t(11;22) EWSR-WT1 translocation characteristic of desmoplastic small round cell tumor. The patient was supported in the hospital and discharged with oncology follow-up. Discussion: As seen in this case, pathology review is essential to ensuring correct diagnosis and appropriate treatment plan. This is especially true when the clinical scenario does not match the listed pathology. Additional diagnostics such as NGS are invaluable in establishing correct diagnosis.

Case report: Alpelisib-induced Stevens-Johnson syndrome.

Background: Alpelisib is a recently approved treatment for hormone receptor-positive, HER2-negative, PIK3CA-mutated advanced breast cancer. It has been associated with alopecia and rash, but there are no documented cases of Stevens-Johnson Syndrome (SJS) associated with this drug. Here, we detail the first case of SJS associated with alpelisib. Case description: Our patient is a 60-year-old woman with a past medical history of metastatic hormone receptor-positive (ER+ 80% and PR+ 1%), HER2-negative metastatic breast cancer who presented with acute odynophagia, fevers, and diffuse body rash after receiving her first doses of alpelisib and fulvestrant in the preceding days. She presented to the emergency department after developing a whole-body rash and severe ulceration of her buccal mucosa. She was started on methylprednisolone with remarkable improvement in symptoms. Conclusion: This case report details the only report of SJS following alpelisib treatment. Immediate cessation of drugs and initiation of steroids are the cornerstone of treatment. Patients who experience such side effects will have to be monitored closely for long-term sequelae associated with SJS, including cutaneous, ocular, and oral sequelae, all of which can profoundly affect the quality of life for cancer patients.

Case series: coronavirus disease 2019 infection as a precipitant of atypical hemolytic uremic syndrome: two case reports.

BACKGROUND: Atypical hemolytic uremic syndrome is an exceedingly rare thrombotic microangiopathy caused by accelerated activation of the alternative complement pathway. CASE PRESENTATION: Here, we report two cases of patients presenting with suspected atypical hemolytic uremic syndrome precipitated by coronavirus disease 2019 infection. The first patient, a 25-year-old Hispanic male, had one prior episode of thrombotic microangiopathy presumed to be atypical hemolytic uremic syndrome precipitated by influenza A, and re-presented with thrombocytopenia, microangiopathic hemolytic anemia, nonoliguric renal failure, and normal ADAMTS13 activity, with confirmed coronavirus disease 2019 positivity. The second patient, a 31-year-old Caucasian female, had no personal history of thrombotic microangiopathy, though reported a family history of suspected atypical hemolytic uremic syndrome. She presented with similar laboratory derangements, oliguric renal failure requiring hemodialysis, and confirmed coronavirus disease 2019 positivity. Both patients were treated with eculizumab with complete resolution of their hematologic and renal complications. CONCLUSION: To our knowledge, this represents the largest case series of atypical hemolytic uremic syndrome precipitated by coronavirus disease 2019 in adults.

Efficacy of Half-Day Workshops for Internal Medicine Interns in Educating Breaking-Bad-News Discussions.

Background: Adequate end-of-life (EOL) care/breaking-bad-news (BBN) discussions with patients are becoming increasingly essential to adequate patient care. Purpose: Whether a half-day workshop would lead to improved confidence in EOL/BBN care discussions for internal medicine interns. Methods: Internal medicine interns (n = 43) were assigned to participate in a half-day workshop at Thomas Jefferson University Hospital. The workshop involved two standardized patient (SP) interactions involving delivering news of a terminal illness/initiating goals of care discussion with the intervention of SP feedback, a didactic and lecture on proper EOL/BBN discussion. Voluntary anonymous surveys before and after the workshop were utilized to assess impact. Results: A majority of interns felt more comfortable with leading EOL care/BBN discussions after the workshop and had a positive experience. Conclusions: A half-day curriculum is efficacious in educating EOL/BBN communication to internal medicine interns, but should be further assessed in a larger more standardized study involving an objective assessment.

Case Report: Concomitant Diagnosis of Plasma Cell Leukemia in Patient With JAK2 Positive Myeloproliferative Neoplasm.

Plasma cell dyscrasias and myeloproliferative neoplasms (MPN) are hematologic malignancies arising from two distinct hematopoietic cell lineages. They rarely occur concomitantly. Here, we report a case of a patient with a recent diagnosis of a JAK2 V617F positive MPN who presented with a new diagnosis of plasma cell leukemia. The patient had presented to the hospital with a leukocytosis predominantly comprised of plasma cells, followed by work-up involving peripheral blood flow cytometry, FISH analysis, and bone-marrow biopsy. FISH analysis was suggestive of a common progenitor cell for these distinct hematologic malignancies. To our knowledge, this case represents the second reported instance of a concomitant JAK2 positive MPN with primary plasma cell leukemia.

Successful liver transplant from a hemophilia A donor with no development of hemophilia A in recipient.

BACKGROUND: Hemophilia A is an X-linked inherited bleeding disorder caused by deficiency of coagulation factor VIII. Factor VIII is activated as part of the intrinsic coagulation cascade. It plays a crucial role as the cofactor in the intrinsic "tenase" complex activating factor X to assist in clot formation. Absence or mutation of this coagulation factor leads to excessive bleeding. Clinical manifestations of hemophilia relate to bleeding from impaired hemostasis, sequelae from bleeding, or complications of coagulation factor infusion. Diagnostic criteria for Hemophilia A include factor VIII activity level below 40% of normal, presence of a mutated F8 gene, and the absence of von Willebrand disease (F8 gene - Genetics Home Reference - NIH. https://ghr.nlm.nih.gov/gene/F8). Patients who have this intrinsic defect in the coagulation cascade have a characteristically prolonged PTT. It is theorized that the majority of factor VIII is synthesized mainly in the liver, by way of liver sinusoidal endothelial cells (Arruda VR. Haematologica. 2015;100(7):849-850). Extrahepatic production also occurs in the endothelial cells, kidneys, and lymphatic tissue. In 1969, Marchioro et al showed that transplantation of normal liver to hemophilia dog could normalize plasma factor VIII levels (Marchioro T L, Science. 1969;163(3863):188-190). These results were subsequently proven in humans. Liver transplantation from hemophilia A donors without factor VIII inhibitor is not commonly performed due to the perceived risk of developing hemophilia A in the recipient. There is currently limited literature aimed at elucidating this risk. We present a case of liver transplantation in a hemophilia A donor to a recipient with no history of hemophilia A with literature reviewis a case report, objective and method do not apply. OBJECTIVE AND METHOD: We did a case report and literature review of a liver transplant receipient fro ma hemohpila A donor. RESULTS: The receipient of the liver from hemophilia A donor did not develop hemophilia post transplant and had normal factor VIII levels. CONCLUSION: To our knowledge, this is only the second case in humans of hemophilia A patient as a donor in liver transplantation. As the indications for liver transplantation have expanded, there is a need to expand the donor list, and possibly not exclude this population as viable donor option.

Examining relationships between age at diagnosis and health-related quality of life outcomes in prostate cancer survivors.

BACKGROUND: Patient reports of health related quality of life can provide important information about the long-term impact of prostate cancer. Because patient symptoms and function can differ by age of the survivor, the aim of our study was to examine patient-reported quality of life and prostate symptoms by age at diagnosis among a registry of Dutch prostate cancer survivors. METHODS: A population of 617 individuals from the Patient Reported Outcomes Following Initial Treatment and Long-Term Evaluation of Survivorship (PROFILES) database was surveyed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30) and prostate symptom (EORTC QLQ-PR25) scales. Age at diagnosis was the main independent variable, with three age categories: 60 years and younger, 61-70 years, and 71 years and older. Dependent variables were the EORTC-QLQ-C30 and EORTC QLQ-PR25 scales, divided into positive and negative outcomes. Positive measures of health-related quality of life included global health, physical functioning, role functioning, emotional functioning, cognitive functioning, and social functioning. Negative outcomes included fatigue, nausea, pain, dyspnea, insomnia, appetite, constipation, and diarrhea. We also assessed sexual activity, and urinary, bowel and hormonal symptoms. Descriptive analyses included frequencies with chi-square tests and medians with Kruskal-Wallis tests. Multivariable adjusted analyses were conducted by median regression modeling. RESULTS: Among the numerous scales showing some unadjusted association with age group, only two scales demonstrated significant differences between prostate cancer patients age 71+ compared to the youngest group (age < 61) after multivariable adjustment. On average, the oldest patients experienced an 8.3-point lower median physical functioning score (ß = - 8.3; 95% CI = - 13.9, - 2.8; p = 0.003) and a 16.7-point lower median sexual activity score (ß = - 16.7; 95% CI = - 24.7, - 8.6; p < 0.001) while controlling for BMI, marital status, time since diagnosis, comorbidities (heart condition), Gleason score, and treatment (prostatectomy). CONCLUSIONS: Results suggest that patient age at diagnosis should be considered among factors that contribute to health-related quality of life outcomes for prostate cancer survivors. IMPLICATIONS FOR CANCER SURVIVORS: A possible reevaluation of screening recommendations may be appropriate to acknowledge age as a factor contributing to health-related quality of life outcomes for prostate cancer survivors.

Fasoracetam in adolescents with ADHD and glutamatergic gene network variants disrupting mGluR neurotransmitter signaling.

The glutamatergic neurotransmitter system may play an important role in attention-deficit hyperactivity disorder (ADHD). This 5-week, open-label, single-blind, placebo-controlled study reports the safety, pharmacokinetics and responsiveness of the metabotropic glutamate receptor (mGluR) activator fasoracetam (NFC-1), in 30 adolescents, age 12-17 years with ADHD, harboring mutations in mGluR network genes. Mutation status was double-blinded. A single-dose pharmacokinetic profiling from 50-800 mg was followed by a single-blind placebo at week 1 and subsequent symptom-driven dose advancement up to 400 mg BID for 4 weeks. NFC-1 treatment resulted in significant improvement. Mean Clinical Global Impressions-Improvement (CGI-I) and Severity (CGI-S) scores were, respectively, 3.79 at baseline vs. 2.33 at week 5 (P < 0.001) and 4.83 at baseline vs. 3.86 at week 5 (P < 0.001). Parental Vanderbilt scores showed significant improvement for subjects with mGluR Tier 1 variants (P < 0.035). There were no differences in the incidence of adverse events between placebo week and weeks on active drug. The trial is registered at https://clinicaltrials.gov/ct2/show/study/NCT02286817 .
