A nationwide field sampling exercise was launched in 2011, to address mounting anecdotal evidence of atypically high honey bee colony mortalities of unexplained origin occurring throughout Portugal. The first approach was to contact 662 beekeepers (≈ 4% of the registered Portuguese beekeepers), via telephone interviews with a view to formulating an 'educated guess' regarding the cases where Nosema apis / Nosema...
Nosemosis is not a recent pathology in Portugal. The etiological agent traditionally associated with it, the microsporidian Nosema apis, is well characterized and was not causing considerable economic damage to the Portuguese apiculture. However, the recent arrival, to the ‘European’ honeybee sphere, of a ‘new’ Nosema species (N. ceranae) has been recurrently considered a relevant contribution to the ‘Colony Co...
To investigate claims of abnormally high honey bee colony mortality in Portugal during 2011, a survey was carried out via telephone interviews. It included 662 (≈ 4%) registered Portuguese beekeepers and followed the basic 'Coloss' questionnaire. Interviewees were selected accounting for total numbers of colonies and the geographical distribution of their apiaries across the country. The 'sampling grid' was set...
Since winter 2006, extensive honey bee colony losses with distinctive features were first reported in the USA ( ‘Colony Collapse Disorder’, CCD). Global research over the past few years attempting to pin point CCD’s most likely causes, recurrently pointed out that no single factor is universally responsible for this disorder. Nevertheless, stressors e.g. the Varroa mite, some ‘new generation’ pesticides, an eve...
The Portuguese beekeeping sector is one of the most resilient and persistent farming activities in the last decade. In the last five years, the figures reveal a counter cycle behavior with an increment in the number of colonies, apiaries and beekeepers, as shown in the National Beekeeping Program: there are 16.403 beekeepers with a total of 550.757 colonies. Following the same positive trend, the conversion fro...
Supranumerary or ectopic parathyroid glands are the main cause of persistent hyperparathyroidism (HPT) in patients with end stage renal disease (ESRD) submitted to parathyroidectomy (PTx). PURPOSE: To evaluate the prevalence and location of parathyroid glands in these patients. METHODS: Thirty-five patients with ESRD and severe secondary hyperparathyroidism (HPT2) had been submitted to total PTx at HUCFF from D...
PURPOSE: To test the use of intraluminal protection in colonic anastomosis without intestinal cleansing. The intraluminal liner was fashioned from porcine submucosa preserved in glycerin and then fixed 10 cm anteriorly to the anastomotic site. This technique was compared with the one used in termino-terminal colonic anastomosis without intraluminal protection. METHODS: Twenty-eight dogs were divided into two gr...
O hiperparatireoidismo é uma manifestação comum na insuficiência renal crônica (IRC), com alta morbi-mortalidade e difícil manejo clínico. As indicações clássicas da paratireoidectomia são: hipercalcemia persistente, principalmente após transplante renal, prurido intratável, fraturas patológicas, dor óssea refratária ao tratamento medicamentoso e calcificação metastática. Infelizmente, esta última não responde ...
A adubação nitrogenada é importante para potencializar a produtividade do milho safrinha, que se tornou a principal cultura de outono-inverno, semeada após a soja, nos seguintes Estados: Paraná, São Paulo, Mato Grosso do Sul, Mato Grosso e Goiás. Com o objetivo de avaliar a produtividade de grãos e outras características agronômicas do milho safrinha em função de doses e épocas de aplicação de N, foi realizado ...
Hyperparathyroidism is a desease caused by increase of parathormone secretion, leading to a misfunction of calcium metabolism. Although not very common among population in general, it is frequently observed in patients with cronic renal disease. It can involve a slight syntomatic form, but as a whole, its main repercurssions occur in skeletic muscles, urinary and intestinal systems. The authors conduct a broad ...
