An outcomes analysis of anterior epistaxis management in the emergency department.

BACKGROUND: Many treatment options exist for the management of anterior epistaxis. However, little is known about treatment outcomes. The objective was to identify the currently utilised methods of management and outcomes for patients with anterior epistaxis presenting to the emergency department (ED) at a Canadian tertiary care center. METHODS: A retrospective review of ED visits from January 2012-May 2014 for adult patients with a diagnosis of anterior epistaxis was performed. Patient demographic data, comorbidities, and treatment methods were documented. The effectiveness of different treatment modalities was determined. RESULTS: Three hundred fifty-three primary anterior epistaxis cases were included. Mean patient age was 70 years and 49% of patients were female. Comorbidities included hypertension (56%), diabetes (19%), CAD (28%), and atrial fibrillation (27%). A large proportion of the cohort (61%) was on at least one anticoagulant or antiplatelet therapy. The most common utilised treatment modalities were silver nitrate cauterization, Merocel®, petroleum gauze packing, nasal clip and 15% were simply observed. Initial treatment success was achieved in 74% of cases. Of patients receiving specific treatment modalities, silver nitrate cauterization had the highest success rate at 80%. 26% of patients returned to the ED for recurrence of epistaxis with highest rates occurring in the nasal clip (59%), Merocel® (26%), and petroleum gauze packing (42%) groups. CONCLUSIONS: The differences in recurrence rate among the different treatment modalities observed may be due to true differences in effectiveness or differences in treatment selection by the ED physicians based on severity of epistaxis. Cauterization with silver nitrate, however, offers the added benefit of no need for follow up. Further study is needed to elucidate the most efficacious treatment modality based on epistaxis severity.

Tissue Factor Pathway Inhibitor Gene Polymorphism -33T → C Predicts Improved Disease-Free Survival in Colorectal Cancer.

BACKGROUND: Tissue factor pathway inhibitor (TFPI) is an anticoagulant with antimetastatic properties. The homozygous CC polymorphism of TFPI (-33T â†’ C) is associated with higher TFPI levels and lower venous thromboembolism risk. This study was the first to evaluate the impact of this polymorphism on disease-free survival (DFS) in cancer patients after curative resection. METHODS: A prospectively maintained tumor bank with clinical data was used to identify patients who underwent curative surgery for colorectal cancer between 1994 and 2006. Germline DNA was extracted from formalin-fixed, paraffin-embedded normal colonic mucosa. Single nucleotide polymorphisms for TFPI (-33T â†’ C), factor V Leiden (G1691A), and prothrombin (G20210A) were determined by polymerase chain reaction. Survival analysis was described using the Kaplan-Meier method. Multivariable regression analysis was performed using the Cox proportional hazard model. RESULTS: Of the 127 patients identified, the CC genotype was found in 11 %. Venous thromboembolism incidence was 18 % in the TT/TC (wild type/heterozygous) genotypes and 7 % in the CC genotype (p = 0.46). The CC genotype was associated with superior DFS (hazard ratio 0.34, 95 % confidence interval 0.14-0.84; p = 0.02) with 5-year DFS of 63 vs. 24 % for CC vs. TT/TC, respectively. In multivariate analysis, CC polymorphism (hazard ratio 0.28, p = 0.008) was independently associated with improved DFS. The prevalence of factor V Leiden (0.8 %) and prothrombin (1.6 %) polymorphisms was too low to detect interaction with TFPI polymorphism or DFS. CONCLUSIONS: These findings indicate that the inherited anticoagulant homozygous -33T â†’ C TFPI polymorphism may protect against colon cancer recurrence and suggests a mediating role for the coagulation system in cancer outcomes.

Treatment outcomes for male breast cancer: a single-centre retrospective case-control study.

BACKGROUND: Male breast cancer (bc) is a rare disease, and the availability of information on treatment outcomes is limited compared with that for female bc. The objective of the present study was to compare disease-free (dfs) and overall survival (os) for men compared with women having early-stage bc. METHODS: This retrospective case-control study compared men and women treated for stage 0-iiib bc at a single institution between 1981 and 2009. Matching was based on age at diagnosis, year of diagnosis, and stage. Treatment, recurrence, and survival data were collected. Kaplan-Meier analysis was used to calculate os and dfs. RESULTS: For the 144 eligible patients (72 men, 72 women), median age at diagnosis was 66.5 years. Treatments included mastectomy (72 men, 38 women), radiation (29 men, 44 women), chemotherapy (23 men, 20 women), and endocrine therapy (57 men, 57 women). Mean dfs was 127 months for women compared with 93 months for men (p = 0.62). Mean os was 117 months for women compared with 124 months for men (p = 0.35). In multivariate analysis, the only parameter that affected both dfs and os was stage at diagnosis. CONCLUSIONS: This case-control study is one of the largest to report treatment outcomes in early-stage male bc patients treated in a non-trial setting. Male patients received systemic therapy that was comparable to that received by their female counterparts, and they had similar os and dfs. These results add to current evidence from population studies that male sex is not a poor prognostic factor in early-stage breast cancer.

Computed tomography angiography intraluminal filling defect is predictive of internal carotid artery free-floating thrombus.

INTRODUCTION: Filling defects at the internal carotid artery (ICA) origin in the work-up of stroke or transient ischemic attack may be an ulcerated plaque or free-floating thrombus (FFT). This may be challenging to distinguish, as they can appear morphologically similar. This is an important distinction as FFT can potentially embolize distally, and its management differs. We describe a series of patients with suspected FFT and evaluate its imaging appearance, clinical features, and evolution with therapy. METHODS: Between 2008 and 2013, we prospectively collected consecutive patients with proximal ICA filling defects in the axial plane surrounded by contrast on CT/MR angiography. We defined FFT as a filling defect that resolved on follow-up imaging. We assessed the cranial-caudal dimension of the filling defect and receiver operating characteristics to identify clinical and radiological variables that distinguished FFT from complex ulcerated plaque. RESULTS: Intraluminal filling defects were identified in 32 patients. Filling defects and resolved or decreased in 25 patients (78 %) and felt to be FFT; there was no change in 7 (22 %). Resolved defects and those that decreased in size extended more cranially than those that remained unchanged: 7.3 mm (4.2-15.9) versus 3.1 mm (2.7-3.7; p = 0.0038). Receiver operating characteristic analysis established a threshold of 3.8 mm (filling defect length), sensitivity of 88 %, specificity of 86 %, and area under the curve of 0.86 (p < 0.0001) for distinguishing FFT from plaque. CONCLUSION: Filling defects in the proximal ICA extending cranially >3.8 mm were more likely to be FFT than complex ulcerated plaque. Further studies evaluating filling defect length as a predictor for FFT are warranted.
