[Spargelstangenuntersuchungen zur Haupterntezeit auf Infektionen mitFusarium spp. und Kontaminationen mit Fumonisin B1 Investigation on asparagus spears during the main harvest byFusarium spp.- infections and contamination by Fumonisin B1].

Asparagus spears collected from a total of six commercial plantings in Austria during the main harvest periods in May and June of 2003 and 2004 were examined for endophytic colonization byFusarium spp., particularlyF. proliferatum. Potentially toxigenic fungi such asF. proliferatum were isolated and identified by morphological characteristics using light microscopy. Fumonisin B1 inF. proliferatum-infected asparagus spears was detected with IAS-HPLC-FLD or HPLC-MS/MS. The identity of endophytic fungi colonizing of a total of 816 individual spears was determined. The incidence of infection byF. proliferatum and otherFusarium spp. was highly dependent on location and sampling date. The dominantFusarium species among the endophytic microflora wasF. oxysporum. Other frequently isolated species includedF. proliferatum, F. sambucinum, F. culmorum, F. avenaceum andF. equiseti. The incidence ofF. proliferatum-infected asparagus spears was less than 10% at four of the six sampling locations. At the two remaining locations, 20-47% of the spears examined were infected withF. proliferatum. Further exploration of FB1 generation in asparagus is required because the low levels of FB1 (10-50 (µg/kg) detected in harvested spears in 2003 and 2004 cannot be explained by the results of this study.

[Ultrasound assessment of reconstructed rotator cuffs]. / Die sonographische Beurteilung rekonstruierter Rotatorenmanschetten.

The evaluation of recurrent shoulder symptoms in patients who have had rotator cuff repair is a diagnostic challenge. Pain and limitation of motion may be caused by a recurrence of the rotator cuff tear. Arthrography is not considered to be helpful in postoperative cases, since it is false-positive in most of them. Pre-operative ultrasonography of the shoulder is regarded as a highly accurate diagnostic tool for rotator cuff tears. The diagnostic criteria used are: the continuity of the rotator cuff, its contour, its thickness and its echogenicity. Our study was aimed at determining which ultrasonographic criteria were significant for a retear. In addition, the "normal" postoperative sonographic appearance of the rotator cuff was established. Of 133 patients with a full thickness rotator cuff tear, 110 were evaluated 4-48 months (mean in 21 months) after surgery. A total of 85 cuffs were reconstructed, in 46 cases by direct suture, in 33 cases by suture to the major tubercle and in 6 cases by tendon transfer (Cofield technique). In 25 cases cuffs the could not be reconstructed. Subacromial decompression was performed routinely. The patients were evaluated clinically by range of movement, force and isometric and impingement tests. The subjective outcome was assessed by the algo-functional index of Patte. Ultrasonography was performed using a 7.5-MHz linear scanner. Each sonographic criterion was referred to the clinical and subjective findings. Ultrasonographic evaluation of the rotator cuffs that could not be reconstructed revealed non-visualization of the tendons. In 13 of the 85 patients in whom reconstruction of the cuff was possible a normal sonographic pattern was seen.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical assessment of maladjusted preschool children.

The authors stress that total assessment prior to intervention is crucial, including standardized testing, observations of behavior, developmental history, and play interview. Techniques presented provide a holistic approach for evaluating the referred preschool child.
