Agricultural land use and human presence around breeding sites increase stress-hormone levels and decrease body mass in barn owl nestlings.

Human activities can have a suite of positive and negative effects on animals and thus can affect various life history parameters. Human presence and agricultural practice can be perceived as stressors to which animals react with the secretion of glucocorticoids. The acute short-term secretion of glucocorticoids is considered beneficial and helps an animal to redirect energy and behaviour to cope with a critical situation. However, a long-term increase of glucocorticoids can impair e.g. growth and immune functions. We investigated how nestling barn owls (Tyto alba) are affected by the surrounding landscape and by human activities around their nest sites. We studied these effects on two response levels: (a) the physiological level of the hypothalamus-pituitary-adrenal axis, represented by baseline concentrations of corticosterone and the concentration attained by a standardized stressor; (b) fitness parameters: growth of the nestlings and breeding performance. Nestlings growing up in intensively cultivated areas showed increased baseline corticosterone levels late in the season and had an increased corticosterone release after a stressful event, while their body mass was decreased. Nestlings experiencing frequent anthropogenic disturbance had elevated baseline corticosterone levels, an increased corticosterone stress response and a lower body mass. Finally, breeding performance was better in structurally more diverse landscapes. In conclusion, anthropogenic disturbance affects offspring quality rather than quantity, whereas agricultural practices affect both life history traits.

The Regulation of Foreign Banks in Switzerland (1956-1972)

The Swiss financial centre witnessed an important shift during the 1960s: the number of foreign banks and their importance in relation to the domestic banking sector significantly increased. Faced with this rapid development, Swiss bank representatives and political and monetary authorities reacted strongly. This paper investigates the evolution of the regulatory response by Swiss banking policy actors to the proliferation of foreign financial in- stitutions. In 1969, those reactions led to the adoption of a discriminatory regime, setting higher entry barriers for foreign banks than for domestic institutions. After examining possible reasons for the attractiveness of Switzerland to foreign banks, this paper will analyse the concerns and fears of the domestic banking sector and its regulators. In this regard, it appears that issues such as mere competition, preservation of the international reputation of the Swiss banks and anti-inflationary monetary policy were central to the chosen regulatory regime. Moreover, this paper shows that foreign banks were used as scapegoats in the evolution of the Swiss system of banking supervision. They were more tightly regulated, yet the general framework remained very lax.

Risques et bénéfices d'une approche interventionnelle face aux corps étrangers digestifs [Digestive foreign body management].

Foreign body (FB) ingestion is a frequent reason for gastroenterology consulting. Eighty percent of these ingestions are accidental and observed among paediatric subjects. However, intentional repetitive ingestions are also observed, especially amongst prisoners or psychiatric patients. Most FBs pass throughout the digestive tract without any complication and without any need for surgical or endoscopic intervention. Nevertheless, around 10-20% of cases require an endoscopy examination and 1% will lead to a surgical intervention. Management approaches should favor inter-disciplinarity, balance benefits and risks of FB removal based on its location, and integrate psychiatric comorbidities into the decision process.

Antifungal activity against planktonic and biofilm Candida albicans in an experimental model of foreign-body infection.

OBJECTIVES: The treatment of Candida implant-associated infections remains challenging. We investigated the antifungal activity against planktonic and biofilm Candida albicans in a foreign-body infection model. METHODS: Teflon cages were subcutaneously implanted in guinea pigs, infected with C. albicans (ATCC 90028). Animals were treated intraperitoneally 12 h after infection for 4 days once daily with saline, fluconazole (16 mg/kg), amphotericin B (2.5 mg/kg), caspofungin (2.5 mg/kg) or anidulafungin (20 mg/kg). Planktonic Candida was quantified, the clearance rate and cure rate determined. RESULTS: In untreated animals, planktonic Candida was cleared from cage fluid in 25% (infected with 4.5 × 10(3) CFU/cage), 8% (infected with 4.8 × 10(4) CFU/cage) and 0% (infected with 6.2 × 10(5) CFU/cage). Candida biofilm persisted on all explanted cages. Compared to untreated controls, caspofungin reduced the number of planktonic C. albicans to 0.22 and 0.0 CFU/ml, respectively, and anidulafungin to 0.11 and 0.13 CFU/ml, respectively. Fluconazole cured 2/12 cages (17%), amphotericin B and anidulafungin 1/12 cages (8%) and caspofungin 3/12 cages (25%). CONCLUSION: Echinocandins showed superior activity against planktonic C. albicans. Caspofungin showed the highest cure rate of C. albicans biofilm. However, no antifungal exceeded 25% cure rate, demonstrating the difficulty of eradicating Candida biofilms from implants.

Congenital lobar emphysema presenting as an airway foreign body.

We report here the case of a 15 months old girl presenting with clinical signs and radiological exams highly suggestive of a foreign body (FB) aspiration. Diagnostic endoscopy revealed an overlooked bronchial malformation responsible for a congenital lobar emphysema (CLE). CLE presenting after one year of age is rare and can easily be misdiagnosed. Therefore, the possibility of an overlooked CLE needs to be known and evoked as an alternative diagnosis when dealing with children presenting with suspected FB aspirations. We report on this unexpected, yet misleading presentation of CLE and review the available literature on the subject.

Multidetector-row computed tomography in the preoperative diagnosis of intestinal complications caused by clinically unsuspected ingested dietary foreign bodies: a case series emphasizing the use of volume rendering techniques

Objective The present study was aimed at describing a case series where a preoperative diagnosis of intestinal complications secondary to accidentally ingested dietary foreign bodies was made by multidetector-row computed tomography (MDCT), with emphasis on complementary findings yielded by volume rendering techniques (VRT) and curved multiplanar reconstructions (MPR). Materials and Methods The authors retrospectively assessed five patients with surgically confirmed intestinal complications (perforation and /or obstruction) secondary to unsuspected ingested dietary foreign bodies, consecutively assisted in their institution between 2010 and 2012. Demographic, clinical, laboratory and radiological data were analyzed. VRT and curved MPR were subsequently performed. Results Preoperative diagnosis of intestinal complications was originally performed in all cases. In one case the presence of a foreign body was not initially identified as the causal factor, and the use of complementary techniques facilitated its retrospective identification. In all cases these tools allowed a better depiction of the entire foreign bodies on a single image section, contributing to the assessment of their morphology. Conclusion Although the use of complementary techniques has not had a direct impact on diagnostic performance in most cases of this series, they may provide a better depiction of foreign bodies' morphology on a single image section.
