Antibiotic resistance patterns of Salmonella and Escherichia coli in the groundwater of Cyprus.

In addition to diet-based vectors of disease, the contribution of water-borne zoonotic agents to gastrointestinal illnesses may be significant, but this has yet to be investigated for Cyprus. Our main objective was to evaluate antibiotic resistance patterns of Salmonella and Escherichia coli in groundwater samples collected at confined animal feeding operations. This is the first report on the occurrence of antibiotic-resistant Salmonella and E.

Isolated right atrial metastasis of malignant melanoma mimicking a myxoma.

Malignant melanoma is the malignancy with the highest propensity for cardiac metastasis. Metastasis to the heart usually occurs in the setting of disseminated disease and is therefore commonly associated with a poor prognosis. We report the case of a 51-year-old woman with a previous history of cutaneous malignant melanoma who presented with a symptomatic, isolated right atrial metastasis attached via a narrow stalk to the interatrial septum, thus resembling a myxoma.

Rapid detection methods for viable Mycobacterium avium subspecies paratuberculosis in milk and cheese.

Mycobacterium avium subsp. paratuberculosis (MAP) may have a role in the development of Crohn's disease in humans via the consumption of contaminated milk and milk products. Detection of MAP from milk and dairy products has been reported from countries on the European continent, Argentina, the UK and Australia.

Localization of accessory pathways by the electrocardiogram: which is the degree of accordance of three algorithms in use?

We evaluated the extent of agreement among three algorithms used for the localization of accessory pathways in patients with overt preexcitation. By the use of one algorithm, three independent couples of observers localized the accessory pathway in 95 consecutive patients showing overt preexcitation in the 12-lead surface electrocardiogram. We defined the following regions: Left atrioventricular ring (LAVR), Right atrioventricular ring (RAVR), Left lateral/left anterolateral (LL/LAL), Left posterior/left posterolateral (LP/LPL), Left posteroseptal (LPS), Right midseptal (RMS), Right posteroseptal (RPS), Right posterior/right posterolateral (RP/RPL), Right lateral/right anterolateral (RL/RAL), and Right anterior/right anteroseptal (RA/RAS).
