Adherence to specific recommended practices when performing epidural corticosteroid injections should lead to a reduction in the incidence of neurologic injuries.

A patient developed signs, symptoms, and radiologic findings compatible with acute subarachnoid hemorrhage after receiving a large dose of heparin and intravascular contrast medium for coronary angiography and stent placement. Subsequent CT indicated the subarachnoid enhancement was due to contrast. Neurotoxicity from contrast agents is well-known, however this is an unusual report of toxicity mimicking subarachnoid hemorrhage clinically and radiologically.

The purpose of this study was to explore participants’ academic experiences and confidence about their academic achievement. Participants ( N = 27) consisted of high-achieving African American male student—athletes from four academically rigorous American universities in the Pac-Ten conference. Most of the participants competed in revenue-generating sports and were interviewed to obtain a deeper understanding of their successful academic experiences. Utilizing a phenomenological approach four major themes emerged: “I Had to Prove I’m Worthy,” “I’m a Perceived Threat to Society,” “It’s About Time Management,” and “It’s About Pride and Hard Work.” Stereotype threat and stereotype reactance are investigated in relation to findings. Recommendations for scholars and practitioners that work with student-athletes are also articulated.

These small canals are routinely visualized on thin section (1 mm) CT of the temporal bone and should not be confused with fractures. This study provides baseline measurements that may be used to evaluate congenital anomalies of these canals. These data may also be helpful in the presurgical evaluation of patients undergoing singular neurectomies for benign positional vertigo.

Purpose. Pretreatment CT volumetric measurement of the primary tumor has been shown to be a predictor of local control in patients with laryngeal carcinoma treated with radiation therapy (RT) alone. A direct association has been demonstrated between tumor volume of supraglottic squamous cell carcinoma (SGSCCA) and local control. However, the association between tumor volume of SGSCCA and local control has not been investigated in patients treated surgically. The purpose of this study was to determine the relationship between SGSCCA tumor volume and local control in patients treated surgically.Materials and Methods. Primary site tumor volume was calculated from pretreatment CT studies in 37 laryngeal supraglottic carcinomas treated surgically. All patients had clinical follow-up for evidence of recurrent tumor along the surgical margins at the primary site for a minimum of 2 years after completion of treatment. Statistical analysis consisted of Mantel-Haenszel chisquare tests and Fisher's exact test.Results. Overall local control rate was 92% (33 of 37). Tumor volume was significantly associated with local control (p <.05). Local control rate for tumors with volumes <16 cc was 94% (32 of 34) (p <.05). Conclusions. Pretreatment CT volumetric analysis is useful for predicting local control in patients with SGSCCA carcinoma treated surgically.
