Anaplastic Large-Cell Lymphoma With Vitreous Humor Involvement.

Purpose: To describe a case of T-cell lymphoma with bilateral vitreous involvement. Methods: A case report was reviewed, and a literature review, including search terms such as "anaplastic large-cell lymphoma (ALCL)" and "T-cell lymphoma with ocular involvement", was performed. Results: A 56-year-old man presented with slurred speech, left-sided weakness, and floaters in his right eye. He was found to have an enhancing right frontal lobe mass with biopsy positive for ALCL. The right eye demonstrated 2+ vitreous cell, with a vitreous biopsy consistent with ALCL. His floaters resolved, and the patient was asymptomatic until he developed floaters in his left eye 1½ years later. A subsequent vitreous biopsy revealed recurrence of ALCL in the fellow eye. Conclusions: ALCL is a rare T-cell lymphoma uncommonly reported as having vitreous infiltration.

Subretinal fluid associated with pemigatinib therapy for cholangiocarcinoma; a case report and literature review Pemigatinib-associated subretinal fluid.

PURPOSE: To describe the retinal findings associated with pemigatinib, an oral competitive inhibitor of fibroblast growth factor receptor (FGFR) approved for the treatment of cholangiocarcinoma. METHODS: We present a case report and performed a literature review, revealing only two prior reported cases of pemigatinib-mediated subretinal fluid. RESULTS: A 72-year-old woman presented with transient visual symptoms while on pemigatinib for the treatment of cholangiocarcinoma. Optical coherence tomography (OCT) revealed subfoveal subretinal fluid bilaterally that resolved during a drug holiday, however fluctuated throughout her treatment course. She remained on pemigatinib for ten months without other ocular sequelae. CONCLUSIONS: This is one of the few reported cases of pemigatinib-related retinopathy, which further supports the self-limited and benign nature of subretinal fluid associated with FGFR inhibitors.

Septic cavernous sinus thrombosis: A review.

Septic cavernous sinus thrombosis (SCST) is a rare, yet severe, process typically arising from infections of the paranasal sinuses (predominately ethmoid and/or sphenoid sinusitis) and less commonly, otogenic, odontogenic, and pharyngeal sources. Clinical symptoms of SCST arise from obstruction of venous drainage from the orbit and compression of the cranial nerves within the cavernous sinus. In the preantibiotic era SCST was considered universally fatal (80-100%); however, with the introduction of antibiotics the overall incidence, morbidity, and mortality of SCST have greatly declined. In spite of dramatic improvements, morbidity and mortality remain high, with the majority of patients experiencing neurological sequalae, highlighting the severity of the disease and the need for prompt recognition, diagnosis, and treatment. Here we review of the literature on SCST with a focus on the current recommendations and recent evidence for diagnostic and medical management of this condition.

External validation of three risk stratification rules in patients presenting with pulmonary embolism and cancer.

Numerous risk stratification rules exist to predict post-pulmonary embolism (PE) mortality; however, few were designed for use in cancer patients. In the EPIPHANY registry, adapted versions of common rules (the Hestia criteria, Pulmonary Embolism Severity Index [PESI], and simplified PESI [sPESI]) displayed high sensitivity for prognosticating mortality in PE patients with cancer. These adapted rules have yet to be externally validated. Therefore, we sought to evaluate the performance of an adapted Hestia criteria, PESI, and sPESI for predicting 30-day post-PE mortality in patients with cancer. We identified consecutive, adults presenting with objectively confirmed PE and cancer to our institution (November 2010 to January 2014). The proportion of patients categorized as low or high risk by these three risk stratification rules was calculated, and each rule's accuracy for predicting 30-day all-cause mortality was determined. Of the 124 patients with PE and active cancer identified, 25 (20%) experienced mortality at 30 days. The adapted Hestia criteria categorized 23 (19%) patients as low risk, while exhibiting a sensitivity of 88% (95% confidence interval [CI] = 68-97%), a negative predictive value NPV of 87% (95% CI = 65-97%), and a specificity of 20% (95% CI = 13-30%). A total of 38 (31%) and 30 (24%) patients were low risk by the adapted PESI and sPESI, with both displaying sensitivities of 92% and NPVs > 93%. Specificities were 36% (95% CI = 27-47%) and 28% (95% CI = 20-38%) for PESI and sPESI. In our external validation, the adapted Hestia, PESI, and sPESI demonstrated high sensitivity but low specificity for 30-day PE mortality in patients with cancer. Larger, prospective trials are needed to optimize strategies for risk stratification in this population.

Mechanical endovascular therapy for acute ischemic stroke: An indirect treatment comparison between Solitaire and Penumbra thrombectomy devices.

BACKGROUND: Randomized controlled trials (RCTs) have compared mechanical endovascular therapy (MET) in addition to intravenous tissue plasminogen activator (IVtPA) to IVtPA alone for the management of acute ischemic stroke (AIS). Direct comparative studies between individual METs are not available. In lieu of head-to-head randomized control trials, we performed an adjusted indirect treatment comparison (ITC) meta-analysis to assess the comparative efficacy and safety of different METs, Solitaire+IVtPA and Penumbra+IVtPA in AIS patients. METHODS AND FINDINGS: We searched MEDLINE, the Cochrane Central Register of Controlled Trials and Embase from January 1, 2005 through April 1, 2017 for RCTs in AIS patients, comparing a single MET+IVtPA to IVtPA alone and reporting shift in ordinal modified Rankin Scale (mRS) score at 90 days. Secondary endpoints included 90 day mortality and symptomatic intracranial hemorrhage (sICH). Endpoints were pooled using traditional random effects meta-analysis methods, producing odds ratios and 95% confidence intervals. Adjusted ITCs using pooled estimates were then performed. Three studies (SWIFT PRIME, EXTEND-IA, THERAPY) were included; two evaluating the Solitaire stent retriever and one the Penumbra system. Traditional meta-analysis demonstrated that each MET+IVtPA resulted in increased odds of improving ordinal mRS score vs. IVtPA alone, but did not alter the odds of death or sICH. Adjusted ITC showed no significant difference between the METs for any outcome. CONCLUSION: No significant difference in efficacy or safety between the Solitaire and Penumbra devices was observed.

External Validation of Generic and Cancer-Specific Risk Stratification Tools in Patients With Pulmonary Embolism and Active Cancer.

Background: Numerous risk stratification tools exist to predict early post-pulmonary embolism (PE) mortality; however, few were specifically designed for use in patients with cancer. This study sought to evaluate the performance of 3 cancer-specific (RIETE, POMPE-C, and Font criteria) and 3 generic (Hestia, Pulmonary Embolism Severity Index [PESI], and Geneva prognostic score [GPS]) risk stratification tools for predicting 30-day post-PE mortality in patients with active cancer. Methods: We identified consecutive, adult, objectively confirmed patients with PE and active cancer presenting to our institution from November 2010 to January 2014. We calculated the proportion of patients categorized as low or high risk by each of the 6 risk stratification tools and determined each tools' accuracy for predicting 30-day all-cause mortality. Results: A total of 124 patients with PE and active cancer were included (mean age, 66.2 years; 46.0% with concurrent deep vein thrombosis; 49.2% with metastatic disease; and 46.8%, 16.9%, and 11.3% receiving chemotherapy, radiation, or both, respectively). Mortality at 30 days occurred in 25 patients (20.2%). The cancer-specific tools (POMPE-C, RIETE, and Font criteria) categorized between 32% and 43% of patients as low risk and displayed sensitivities and specificities of 88.0% to 96.0% and 38.4% to 52.5%, respectively. The generic PESI and Hestia tools had sensitivities >96.0%, but classified <19% of patients as low risk; specificity of these tools were low (PESI, 6.1%; Hestia, 23.2%). Although the final noncancer tool, GPS, classified 43.5% of patients as low risk, it did so with a sensitivity of 52.0% and specificity of 42.4%. Conclusions: When risk-stratifying PE in patients with active cancer, cancer-specific tools appeared to exhibit better prognostic accuracy than their generic counterparts. POMPE-C, RIETE, and the Font criteria identified a substantially greater proportion of patients with PE likely to survive to 30 days with comparable sensitivity to the generic tools.
