Leptomeningeal carcinomatosis (LC) is a rare leptomeningeal spread of diffusely metastatic tumors. It occurs more commonly with hematologic tumors, less commonly with solid tumors, and is exceedingly rare in prostate cancer. Due to its scarcity, it has traditionally been difficult to diagnose LC but advancement of MRI has helped considerably. However, even with technological improvements, pre-mortem diagnosis of LC remains difficult and controversial. Our case is a 71-year-old male with prostate cancer with bone metastases who presented to our facility with altered mental status (AMS), lower extremity weakness, and worsening diarrhea. The diarrhea was responsive to antibiotic therapy, but his AMS did not resolve. A head CT without contrast was negative but follow-up brain MRI revealed leptomeningeal enhancement highly suggestive of LC. Cerebrospinal fluid (CSF) cytology results were negative and other CSF studies were inconclusive. Although further studies were planned, the patient continued to deteriorate, and the family elected to withdraw care. He passed away without beginning treatment for the LC. Despite advances in cancer therapies, LC remains difficult to diagnose and treat. Imaging may be suggestive of the condition but the confirmatory tests such as repeated CSF cytology or meningeal biopsy are not only invasive but also usually occur postmortem. Additional methods of CSF testing have been studied to evaluate their role in accurately diagnosing LC but low specificity for LC has somewhat limited their use. Although treatment options are mainly palliative in nature, prompt recognition and early treatment could grant valuable time for patients and families.
IntroductionContrast-induced nephropathy (CIN) is the third most common cause of iatrogenic acute renal failure and is triggered by administration of radiopaque contrast media. Periprocedural hydration is imperative in prevention of CIN, and uric acid has been recognized to have an integral role in development of renal disease. The aim of our study is to understand the efficacy of allopurinol in preventing CIN among patients undergoing percutaneous coronary intervention.Material and methodsA literature search was performed on PubMed (Medline), Science Direct and Cochrane Library using a combination of Mesh terms. We limited our search to randomized controlled trials (RCTs) and articles published in the English language. The PRISMA protocol was utilized to conduct this meta-analysis.ResultsSix studies were included in the final analysis. All included studies were clinical trials conducted between 2013 and 2019. A total of 853 patients were included. There was a significant reduction in the risk of CIN among patients who were pretreated with adequate hydration plus allopurinol (100 to 600 mg) compared to hydration only before undergoing percutaneous coronary angiography (RR = 0.39, 95% CI: 0.21–0.73). A sensitivity analysis of studies using 300 mg of allopurinol only reported a significant reduction in CI-AKI compared to hydration alone (RR = 0.26, 95% CI: 0.11–0.57).ConclusionsOur study demonstrates that Allopurinol is effective in preventing contrast-induced nephropathy in patients undergoing percutaneous coronary intervention. Larger clinical trials are warranted to better understand this effect.
IntroductionDue to high levels of intravenous drug use (IVDU) in West Virginia (WV), there are increasing numbers of hospitalizations for infective endocarditis (IE). More specifically, pregnant patients with IE are a uniquely challenging population, with complex management and a clinical course that further affects the health of the fetus, with high morbidity and mortality. Timely recognition and awareness of the most common bacterial causes will provide hospitals and clinicians with valuable information to manage future patients.
MethodsThis retrospective study analyzed the clinical course of pregnant patients admitted with IE and IVDU history presenting at Cabell Huntington Hospital from 2013 to 2018. Inclusion criteria were women between 16 and 45 years of age confirmed to be pregnant by urine pregnancy test and ultrasonography with at least eight weeks gestation, with a first-time diagnosis of endocarditis and an identified history of IVDU. We excluded charts with pre-existing risk factors including a history of valvular disease, rheumatic heart disease, surgical valve repair or mechanical valve replacement, or a diagnosis of coagulopathies. The resulting charts were evaluated for isolated organisms, reported clinical course, and complications of the pregnancy.
ResultsA total of 10 patients were identified, with methicillin-susceptible and methicillin-resistant Staphylococcus aureus, Serratia marcescens, Haemophilus parainfluenza, and Enterococcus faecalis species. Complications included loss of fetus (30%), septic embolization (40%), hemorrhagic stroke (10%), and transfer to outside facilities for cardiothoracic surgical intervention (40%).
DiscussionIE in pregnancy, while rare, has serious complications. In the context of the IVDU epidemic, it has an increasing impact on WV hospitals. A better understanding of the clinical course may allow for early diagnosis and guide the development of rational empiric therapies. More effective management of IE in pregnant patients can reduce complications and potentially improve maternal and fetal morbidity or mortality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
