A food-borne outbreak of Shigella sonnei gastroenteritis, Austria, 2008.
We report on the first foodborne outbreak of Shigella sonnei described in Austria. On July 14 2008, AGES was informed of a cluster of 22 laboratory-confirmed cases of infection with S. sonnei restricted to public health district X in the province of Salzburg. All cases had attended a youth-group trip to a small village in the province of Tyrol from July 7 to July 9. ⋯ Among the 42cases, 34 could be explained by consumption of salad. The landlady of the hostel, who prepared the salad with bare hands, was a carrier and was assumed to be the source of contamination of the salad. Without proper epidemiological analytical investigation of this shigellosis outbreak, its association with food consumption would not have been identified.

Sonographic evaluation of unexplained pleural exudate: a prospective case series.
Thoracic ultrasound may be helpful in differentiating between malignant and tuberculosis-associated pleural exudate. This study aimed to evaluate its utility in patients with unexplained pleural exudate. ⋯ Thoracic ultrasound is a useful bedside method for differentiation of the etiology of pleural exudate. When a complex septal pattern is found, pleural needle biopsy should be the next diagnostic procedure, whereas with less complex pleural sonography findings other methods should be pursued.

Carbohydrate epitopes as a cause of cross-reactivity in patients allergic to Hymenoptera venom.
Among patients with allergy to insect stings, double positivity in tests for IgE antibodies specific to honey bee and wasp venoms is a frequent diagnostic problem. True double sensitization and possible cross-reactivity of venom hyaluronidases and with carbohydrate determinants must be considered in such patients. We studied the frequency of sensitization to carbohydrate determinants and the role of these in double positivity in tests for specific IgE antibodies. ⋯ The values of IgE specific for OSR pollen and MUXF3 in patients with primary sensitization to either honey bee venom or wasp venom were significantly higher than in patients with double sensitization. These results confirm that IgE antibodies against carbohydrates epitopes are a frequent cause of double positivity in tests for anti-venom IgE antibodies.

Clinical TrialTreatment of inappropriate sinus tachycardia with ivabradine.
Inappropriate sinus tachycardia is most often treated with beta-blockers; in resistant cases, nonpharmacologic treatment has been attempted. Recent case reports have shown a favorable response to ivabradine in some patients. ⋯ The results of our study show that patients with inappropriate sinus tachycardia can be successfully treated with ivabradine.

Case ReportsChicken-bone perforation of a sigmoid colon diverticulum into the right groin and subsequent phlegmonous inflammation of the abdominal wall.
Colonic diverticula are frequent in western countries and approximately 80% of patients who develop diverticulitis are elderly. The sigmoid and descending colon are most commonly involved. Clinical manifestations range from asymptomatic diverticula to life-threatening complications such as diverticulum perforation and subsequent peritonitis. ⋯ A Hartmann's procedure with necrectomy of the abdominal wall was performed. Histopathologic examination revealed an ingested chicken bone perforating the diverticulum. When diverticulitis or diverticular abscess is suspected in an elderly patient, foreign body impaction or perforation should be considered as a possible cause.
