We describe a case of a 53-year-old woman with interrupted aortic arch, bicuspid aortic valve, and post-interruption saccular aneurysm of the aorta. To our knowledge, this is only the second report of an adult patient with all 3 abnormalities. We also review the literature on this unusual condition and discuss its relationship with coarctation of the aorta.

Since they were first reported in the early 1980s, many advancements have been made in terms of their diagnosis and treatment. Despite the progress made, the origin of these rare tumors and effective newer treatment strategies remain elusive. Central neurocytomas represent 0.1-0.5% of all primary brain tumors. Since they are typically intraventricular, these tumors tend to present clinically with hydrocephalus. CT scanning and MRI are useful in localizing these tumors; however, due to their numerous ambiguous features, the ultimate diagnosis relies on immunohistochemistry and electron microscopy studies of sampled tissue. Currently, surgical removal with a gross-total resection of these tumors is the treatment of choice. Various radiotherapy techniques, including both conventional radiotherapy and stereotactic radiosurgery, have been shown to be useful in cases of residual tumor after sub-total resection and tumor recurrence. The benign nature of these tumors tends to offer a favorable outcome for most patients; however, recurrence rates are relatively high and tumors with high-grade features or extraventricular location tend to have a less favorable prognosis. We present a comprehensive review of these rare tumors, including their epidemiology, clinical presentation, radiological presentation, histopathological findings, and options for intervention including surgery, radiation therapy, stereotactic radiosurgery, and chemotherapy.

Patients often present with late-stage disease, and survival outcomes are reportedly worse than those for SCCa in other regions of the larynx. Analysis of a population-based tumor registry. Academic medical center. The US National Cancer Institute's Surveillance, Epidemiology, and End Results database was queried for cases of subglottic SCCa from 1973 to 2011 (889 cases). Resulting data were analyzed, including patient demographics, therapeutic measures, and survival outcomes. Subglottic SCCa most frequently occurred in the fifth to seventh decade of life, with a mean age at diagnosis of 65.7 ± 11.3 years. There was a strong male predilection, with a male:female ratio of 3.83:1. Most patients were stage III and IV (64.4%) per the American Joint Committee on Cancer. The most common treatment modality was a combination of radiotherapy and surgery (38.8%), followed by radiot...

Primary sinonasal MEC (SN-MEC) is rare. This study analyzes the demographic, clinicopathologic, and survival characteristics of SN-MEC and establishes comparisons with primary major SG-MEC. The Surveillance, Epidemiology, and End Results (SEER) database (1973 to 2010) was queried for SN-MEC (149 cases) and SG-MEC (4234 cases). Data were analyzed comparatively with respect to various demographic and clinicopathologic factors. Survival was analyzed using the Kaplan-Meier and Cox proportional hazards models. Mean ± standard deviation (SD) age at diagnosis for SN-MEC was 58.6 ± 16.6 years. High histologic grade (ie, grades III and IV) at the time of diagnosis was more common among SN-MEC than SG-MEC (42.3% vs 25.5%, p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.0001).

For SN-MEC, factors associated with poor prognosis were age (75+ years; hazard ratio [HR], 3.38; 95% confidence interval [CI], 1.25 to 9.51), higher tumor grade (grade III and IV; HR, 3.62; 95% CI, 1.75 to 8.22), larger tumor size (&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;4 cm; HR, 8.36, 95% CI, 1.59 to 153.74), and primary tumor site (ethmoid sinus; HR, 2.95; 95% CI, 1.28 to 6.23) (all p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.05).

This report represents the largest series of SN-MEC to date. Although SN-MEC and SG-MEC share a common histology, there are important clinical differences between the 2 conditions.

There are two ways of post processing. First word level correction and second sentence level correction in document. The word level is performed in two ways first, finding error and finding dictionary by most similar word. That is called dictionary based approach. Another method to find most probable word is known as probabilistic approach. In order to generate the probabilistic model which includes unigram, bigram, trigram, online resources from various Gujarati newspaper websites are used. The proposed system will use models like Naïve Bayes and Hidden Markov Model to correct word level error. The system will be tested on synthetic dataset which is generated by adding random word level error in the actual document.
