Thrombotic Microangiopathy Associated With Synthetic Cannabinoid Receptor agonists
Marijuana is one of the most commonly used recreational drugs in the United States. As marijuana is illegal in the majority of countries, the use of readily available and unregulated synthetic cannabinoids (SCBs) has increased. Little is known about the potential adverse effects of SCBs especially in regards to their nephrotoxicity. Case reports of acute kidney injury (AKI) from acute tubular injury secondary to their use have been reported. However, the exact pathology, mechanism, and extent of renal injury remain unknown. We report the first case of biopsy proven thrombotic microangiopathy (TMA) associated with SCBs resulting in AKI. The patient suffered significant morbidity with loss of renal function eventually requiring renal replacement therapy
Chemotherapy Used to Halt Lower GI Bleeding in a Rare Case of Metastatic Choriocarcinoma to the GI Tract
Choriocarcinoma, a nonseminomatous germ cell tumor, is a rare type of testicular malignancy that tends to occur in young males. It is, however, exceedingly rare for choriocarcinoma to involve the GI tract. In this article, we present a rare case of a 31-year-old male, diagnosed with choriocarcinoma of the left testes, along with several metastases to distant sites. The patient presented with headaches and severe lower GI bleeding due to metastases to the GI tract, which was eventually controlled with systemic chemotherapy, while requiring several units of packed RBCs during his admission to the hospital. An extensive literature review found very few cases of the occurrence of GI bleeding as a consequence of choriocarcinoma due to metastases to the GI tract
SRSF2 mutations in myelodysplasia/myeloproliferative neoplasms
Abstract Recurrent gene mutations have been described with varying frequencies in myelodysplasia (MDS) /myeloproliferative neoplasm (MPN) overlap syndromes (MMOS). Recent work has placed significant focus on understanding the role of gene lesions involving the spliceosomal machinery in leukemogeneis. SRSF2 is a gene encoding critical spliceosomal proteins. SRSF2 mutations appear to play an important role in pathogenesis of MMOS, particularly in chronic myelomonocytic leukemia. Inhibition of splicing may be a new therapeutic approach. E7107, a spliceosome inhibitor, has been shown to differentially inhibit splicing more in SRSF2-mutant cells leading to decreased leukemia burden in mice. H3B-8800 is a small molecule modulator of spliceosome complex and has been shown to lower leukemia burden in SRSF2-P95H mutant mice. This review focuses on the incidence of mutant SRSF2 across various MMOS as well as recent clinical development of spliceosome inhibitors
Kaposi Sarcoma Inflammatory Cytokine Syndrome (KICS): A Rare but Potentially Treatable Condition
Extra-hepatic bile duct hamartoma in a 10-month-old with a morgagni hernia and multiple anatomical anomalies: a rare and incidental finding
Von Meyenburg complexes (VMCs), also known as bile duct hamartomas, are a part of a group of ductal plate malformations. They are typically present intrahepatically. In this case, we present to our knowledge the first report of an extra-hepatic VMC in the pediatric population. The patient presented as a 10-month-old infant with a weeklong history of progressive breathing difficulty. A chest radiograph was obtained, showing intestinal loops in the thoracic cavity consistent with a Morgagni\u27s hernia, unrelated to his breathing difficulty. The patient then underwent an elective repair of his congenital diaphragmatic defect. During the operation, the bile duct hamartoma was found adherent to the accessory lobe of the liver, present to the left of the ligamentum teres
Everolimus for the Treatment of Advanced Pancreatic Ductal Adenocarcinoma (PDAC)
Introduction: PDAC is a lethal malignancy with a clear unmet need; almost all patients fail 1(st), 2(nd), and 3(rd) line multi-agent cytotoxic chemotherapy. The mammalian target of rapamycin (mTOR) has been identified as a key signaling node enhancing tumor survival and drug resistance in PDAC; hence, it is considered a promising therapeutic target. Areas covered: We comprehensively reviewed the evidence from preclinical and phase I and II clinical trials, based on the authors\u27clinical experience and a PubMed, Cochrane library, Embase, and Google Scholar search everolimus + pancreatic cancer. Expert opinion: Everolimus has not demonstrated efficacy in PDAC; however, an mTOR inhibitor in combination with stroma-targeted therapies may be a promising area to explore in clinical trials
Implementation of a Low-Cost Quality Improvement Intervention Increases Adherence to Cancer Screening Guidelines and Reduces Healthcare Costs at a University Medical Center
Adherence to US Preventative Services Task Force (USPSTF) cancer screening guidelines remains considerably lower than the recommendation of the Healthy People 2020 initiative. Patient populations recommended for screening are not screened at an appropriate rate, and populations not recommended for screening are inappropriately screened. Closer adherence to guidelines should improve outcomes and reduce costs, estimated to reach 998,316 (95% CI; 1,352,148). We showed a significant absolute increase in USPSTF knowledge of 28.3% irrespective of the house staff level that remained high at 2 years from the educational intervention. The low-cost HM card increased appropriate knowledgeable cancer screening adherence while reducing unnecessary testing and producing substantial savings to the healthcare system
Atypical hemolytic uremic syndrome in first trimester pregnancy successfully treated with eculizumab
Abstract
Background
Atypical hemolytic uremic syndrome is a rare disorder which is known to cause acute thrombotic microangiopathy during pregnancy with poor maternal and fetal outcomes. Atypical hemolytic uremic syndrome is caused mostly by dysregulation of alternative complement pathway secondary to genetic mutations. Most of the cases reported have been in the post-partum period. We report a rare case of a patient who presents with thrombotic microangiopathy in the first trimester of her eleventh pregnancy and was successfully treated with eculizumab.
Case presentation
A 30-year-old woman presented at 10\ua0weeks of gestation with hypertension, hemolytic anemia, thrombocytopenia, and acute kidney injury, consistent with thrombotic microangiopathy. She was managed initially with daily plasmapheresis. However, her kidney function did not recover, requiring hemodialysis. ADAMTS13 activity was later found to be within normal limit, hence diagnosis of atypical hemolytic uremic syndrome was strongly considered at that time and she was immediately treated with anti-C5 humanized monoclonal antibody (eculizumab). The patient responded well (resolution of thrombotic microangiopathy and recovery of renal function) to eculizumab, with continued remission after discharge and successfully delivered a healthy baby at term without any peripartum complications.
Conclusion
Early recognition of atypical hemolytic uremic syndrome is often difficult as several other conditions also manifest as thrombotic microangiopathy during pregnancy, causing delay in initiating appropriate treatment. Our case suggests that treatment of atypical hemolytic uremic syndrome in early trimester of pregnancy with eculizumab results in good outcome to mother and fetus
