Imaging in Chronic Traumatic Encephalopathy and Traumatic Brain Injury.

Context: The diagnosis of chronic traumatic encephalopathy (CTE) can only be made pathologically, and there is no concordance of defined clinical criteria for premorbid diagnosis. The absence of established criteria and the insufficient imaging findings to detect this disease in a living athlete are of growing concern.

Evidence Acquisition: The article is a review of the current literature on CTE.

Drug Use in the Twittersphere: A Qualitative Contextual Analysis of Tweets About Prescription Drugs.

Tweets about prescription opioid use may reveal insights into the prescription drug epidemic. We qualitatively assessed 2,100 tweets about prescription opioids utilizing a Twitter Archiving Google Spreadsheet® and determined whether the tweet represented: abuse (i.e.

Accuracy of body weight perception and obesity among Chinese Americans.

Background: Accuracy of body weight perception is an individual's perception of their body weight in comparison with actual body weight and is associated with weight-related behaviors. Chinese Americans have increased risk for obesity but no studies have examined accuracy of body weight perception.

Methods: This study was a descriptive and cross-sectional study, which was conducted in a community health center in New York.

Sebaceous carcinoma of the maxillary gingival: First reported case involving the gingiva.

Sebaceous carcinoma of the oral cavity is extremely rare. To date, only 9 cases of primary sebaceous carcinoma involving the oral cavity have been reported in the English literature, with the majority of cases occurring on the buccal mucosa. This report describes a case of sebaceous carcinoma involving the maxillary gingiva.

Ossifying fibromyxoid tumor of the breast mimicking fibroadenoma: a case report and differential diagnoses.

An 80-year-old woman presented with a palpable mass in the right breast. Mammographic findings were consistent with calcified fibroadenoma. An ultrasound was performed that showed a solid nodule with peripheral calcification.

Malignant rhabdoid tumor of the floor of mouth: first reported case in the oral cavity of an adult.

Malignant rhabdoid tumors (MRTs) are exceedingly rare lesions. To our knowledge, only 2 cases have been reported in the oral cavity, with both examples occurring in infants. The current case is the third reported case of MRT of the oral cavity and the first reported case to occur in an adult at this location.

Clinical presentation of retinoblastoma in a middle-income country.

The presenting features of retinoblastoma in developing countries and their correlation with disease stage and patient survival are poorly known and they may be useful as background information for planning early diagnosis initiatives. Therefore, we undertook a retrospective review of 508 patients (467 evaluable, 296 unilateral) treated in Argentina from 1988 to 2008. Patients presented at an older age than reported from high-income countries [mean age 24 mo (range, 0 to 165 mo), 31 mo for unilateral (range, 0 to 165 mo), and 13.

Acute kidney injury from pyelonephritis in an elderly man: case report.

Pyelonephritis is rarely considered in the differential diagnosis of acute kidney injury. Acute non-obstructed bacterial pyelonephritis is an infrequent and rarely considered cause of rapidly progressive acute kidney injury. A diagnostic challenge thus develops as it is difficult to clinically differentiate acute kidney injury secondary to ischemic or toxic acute tubular necrosis or papillary necrosis versus acute interstitial nephritis secondary to drugs or infectious pyelonephritis.

Management strategies for the open abdomen: survey of the American Association for the Surgery of Trauma membership.

Purpose: The purpose of this study is to report results from a survey of members of the American Association for the Surgery of Trauma (AAST) on strategies for management of the open abdomen.

Material And Methods: Invitations to participate in a web-based survey were sent to AAST members via email.

Main Results: The response rate was 26%.

Complications of percutaneous endoscopic and fluoroscopic gastrostomy tube insertion procedures in 378 patients.

Gastrostomy tubes are used for primary and supplemental feeding and gastric decompression. The purpose of the study was to compare the complication rate of gastrostomy tube placement by either endoscopic or fluoroscopic technique. Between 1996 and 2004, the surgical and radiological services at a Level I trauma hospital placed gastrostomy tubes in 378 patients (endoscopy=268, fluoroscopy=110).

Difficulty breathing: agreement of paramedic and emergency physician diagnoses.

Objective: To determine the diagnostic accuracy of paramedics treating patients who have called an ambulance for "difficulty breathing."

Methods: A retrospective study of all ambulance call reports generated by one ambulance over a one-year period with the dispatch complaint of "difficulty breathing" taken to the hospital. The paramedic diagnosis on the call report was compared with the emergency department (ED) physician diagnosis, which was used as the "gold standard.

Comparison of intravenous iron sucrose to oral iron in the treatment of anemic patients with chronic kidney disease not on dialysis.

Background: Few studies compare oral to intravenous (IV) iron for managing anemia in patients with chronic kidney disease (CKD) not on dialysis.

Methods: We enrolled 96 CKD anemic patients on erythropoietin in a randomized, open-label, multicenter, controlled study. Patients received 29 days of oral FeSO4 (325 mg t.

Subacute endocarditis caused by Gemella haemolysans and a review of the literature.

We report the first documented case of Gemella haemolysans endocarditis in the United States in a patient following denture fixation. G. haemolysans was isolated form the patient's blood cultures.

Primary carcinoid tumor of the prostate with concurrent adenocarcinoma: a case report.

Prostatic adenocarcinomas commonly exhibit neuroendocrine differentiation as demonstrated by immunohistochemistry. However, true carcinoids of the prostate are rare. We describe herein a case of a primary carcinoid occurring synchronously with a conventional adenocarcinoma in the prostate of a 66-year-old man.

Fluoroscopic balloon-guided transesophageal echocardiography in a patient with Zenker's diverticulum.

During the past 20 years, transesophageal echocardiography (TEE) became an important diagnostic technique. Indications for TEE include: defining the cause and severity of native valve disease, particularly mitral regurgitation; detecting vegetations and other sequelae of endocarditis; assessing prosthetic valve function; and identifying a potential cardiac source for emboli.(1) TEE is usually well tolerated and is associated with few adverse events.

Transbronchial needle aspiration of central and peripheral nodules.

Wang and Terry first described the technique of sampling of mediastinal lymph nodes using a flexible bronchoscope (FB) in 1983. Since then, the scope of transbronchial needle aspiration (TBNA) has increased enormously, and its value for diagnosis of central and peripheral lung lesions, even in the absence of endobronchial disease, is now recognized. Improvements in the diagnostic yield of TBNA aspirates, and increasing knowledge of predictors of a positive aspirate, has reduced the need for mediastinoscopy, and occasionally thoracotomy, with benefits in terms of reduced healthcare costs and improved patient welfare.
