Brachial plexus injury represents the most severe nerve injury of the extremities. While obstetric brachial plexus injury has showed a reduction in the number of cases due to the improvements in obstetric care, brachial plexus injury in the adult is an increasingly common clinical problem. The therapeutic measures depend on the pathologic condition and the location of the injury: Preganglionic avulsions are usually not amenable to surgical repair; function of some denervated muscles can be restored with nerve transfers from intercostals or accessory nerves and contralateral C7 transfer. Postganglionic avulsions are repaired with excision of the damaged segment and nerve autograft between nerve ends or followed up conservatively. Magnetic resonance imaging is the modality of choice for depicting the anatomy and pathology of the brachial plexus: It demonstrates the location of the nerve damage (crucial for optimal treatment planning), depicts the nerve continuity (with or without neuroma formation), or may show a completely disrupted/avulsed nerve, thereby aiding in nerve-injury grading for preoperative planning. Computed tomography myelography has the advantage of a higher spatial resolution in demonstration of nerve roots compared with MR myelography; however, it is invasive and shows some difficulties in the depiction of some pseudomeningoceles with little or no communication with the dural sac.

Purpose: To investigate the feasibility of implementing a novel approach for patient-specific QA of TomoDirectTM whole breast treatment. Methods: The most currently used TomoTherapy DQA method, consisting in the verification of the 2D dose distribution in a coronal or sagittal plane of the Cheese Phantom by means of gafchromic films, was compared with an alternative approach based on the use of two commercially available diode arrays, MapCHECK2TM and ArcCHECKTM. The TomoDirectTM plans of twenty patients with a primary unilateral breast cancer were applied to a CT scan of the Cheese Phantom and a MVCT dataset of the diode arrays. Then measurements of 2D dose distribution were performed and compared with the calculated ones using the gamma analysis method with different sets of DTA and DD criteria (3%-3 mm, 3%-2 mm). The sensitivity of the diode arrays to detect delivery and setup errors was also investigated. Results: The measured dose distributions showed excellent agreement with the TPS calculations for each detector, with averaged fractions of passed Γ values greater than 95%. The percentage of points satisfying the constraint Γ < 1 was significantly higher for MapCHECK2TM than for ArcCHECKTM and gafchromic films using both the 3%-3 mm and 3%-2 mm gamma criteria. Both the diode arrays show a good sensitivity to delivery and setup errors using a 3%-2 mm gamma criteria. Conclusions: MapCHECK2™ and ArcCHECKTM may fulfill the demands of an adequate system for TomoDirectTM patient-specific QA. [ABSTRACT FROM AUTHOR]

Listeria monocytogenes is an important foodborne pathogen that causes gastrointestinal disorders, and, especially in immunocompromised people, serious extraintestinal diseases, such as septicemia and meningitis, as well as abortion in pregnant women. Many foods, from both plant and animal origin, have been involved in listeriosis outbreaks. This article reports the results of a 12-year survey (1993 through 2004) on the presence of L. monocytogenes in several kinds of food marketed in Italy. Of 5,788 analyzed samples, 121 (2.1%) were contaminated with L. monocytogenes. The highest prevalence was found in smoked salmon (10.6%) and in poultry meat samples (8.5%) and the lowest in red meat (0.3%). L. monocytogenes was not found in 154 samples of fresh seafood products. Fifty-two isolates were also serotyped by the agglutination method. The most common serotypes detected in the 52 strains tested were l/2a (36.5%), followed by 1/2c (32.8%), 1/2b (13.5%), 4b (11.5%), 3a (3.8%), and 3b (1.9%). The results of the present study showed low levels of L. monocytogenes in the analyzed samples. A total of 61.5% of the 52 L. monocytogenes strains analyzed belonged to serotypes 1/2a, 1/2b, and 4b, namely the serovars that are most commonly involved in extraintestinal human listeriosis outbreaks. In the ready-to-eat samples, these three serotypes were 40.0% (1/2a), 17.1% (1/2b), and 14.3% (4b). This finding highlights the need to implement strict hygienic measures during the production, distribution, and sale of foods to reduce the risk of foodborne listeriosis in humans to an acceptable level.

Background: The National Cancer Institute's (NCI's) Cancer Information Service (CIS) Partnership Program involves collaboration with over 900 organizations and coalitions serving minority and medically underserved populations. Cancer Information Service collaborations are categorized into three types: networking, educational program, and program development partnerships.Methods: A survey of CIS partnership organizations (n = 288).Results: Most respondents reported that partnerships with CIS are collaborative and make good use of their organization's skills and resources, and most perceive that the benefits of partnership outweigh any drawbacks. More than one-quarter say partnerships have not done a good job evaluating collaborative activities. Results vary among three types of partnerships.Conclusions: Evaluation of the CIS Partnership Program presents an opportunity to examine how a large-scale and multi-faceted partnership effort has been implemented, how it is evaluated, and initial indicators of program success. Organizations, health professionals, and community leaders interested in effective partnerships can use these findings to strengthen collaborations and maximize outcomes. [ABSTRACT FROM AUTHOR]

The National Cancer Institute's (NCI's) Cancer Information Service (CIS) provides cancer information to the public via 1-800-4-CANCER, a smoking quitline, and online. The 2003 National User Survey assessed satisfaction and outcomes among users contacting NCI's CIS by telephone and LiveHelp, an instant messaging service. Ninety-five percent of respondents were very satisfied/satisfied and 88% said their expectations had been met/exceeded. Users reported increased knowledge and self-efficacy. Most had discussed CIS information with a health professional or planned to do so. Of those who contacted CIS about smoking/tobacco use, 14% had quit and 35% cut back. The CIS provides a highly valued, effective service for patients and health professionals. [ABSTRACT FROM AUTHOR]
