Pmc. enl. Soc. Ont 131 : 133-138 The amount and type of pollen collected during the period of apple bloom (25-3 1 May, 1995) were determined for honey bee colonies of Bnckfast and Ontario stocks that had been matched on the basis of brood area. The Buckfast colonies collected 62% more pollen (approximately 18,770 more pollen foraging trips per colony per day) than the Ontario colonies. The prop...

When some scientists hear the word "bioethics," they break out in intellectual hives. They shouldn't. Good bioethics is about enabling science to move forward. Bioethics pushes scientists to acknowledge that they operate not within a vacuum but within a society in which diverse perspectives and values must be engaged. Bioethicists give voice to those divergent perspectives and provide a framewo...

According to the studied population, there are different causes of anaphylaxis in children. Generally, anaphylaxis in hospital is result from medications and latex, but the food allergy is the most common cause of allergy out of the hospital [1]. In the west countries, allergy to peanut is the most important cause of anaphylaxis due to foods. The main pathologic manifestations in this fatal ana...

Chronic urticaria is defined as episodic or daily hives lasting for at least 6 weeks and impairs quality of life. Two main subtypes include chronic idiopathic (spontaneous) urticaria and inducible (physical) urticaria, but some patients have urticarial vasculitis. "Autoimmune chronic urticaria" implies the presence of histamine releasing or mast cell activating autoantibodies to IgE or FcϵRI, t...

Chlorhexidine is an antiseptic and disinfectant used in surgical and clinical practice since 1954 and is available in aqueous or alcoholic solutions 0.5%-4.0% and has a broad-spectrum activity. Despite their widespread use, allergic reactions with chlorhexidine are rarely reported. We describe a case of anaphylaxis with chlorhexidine during a septoplasty, turbinectomy, and maxillary sinusectomy...

ing was present. The last menstrual period had started 14 days previously. There was no history of nocturia, dysuria, frequency or backache. Irregular acquired dysmenorrhcea had been noted in the past. A similar attack had occurred two months previously on a train trip from Calcutta and lasted a few days. The patient had shortly afterwards a routine annual physical examination by another physic...

bees at two sites where hives were surrounded by dense occurrences of aloes. Nectar from this plant is considered to be important for bee honey reserves, although it is known to be dilute compared with other sources. The researchers measured the crop volumes of bees at foraging sites around the aloe flowers and also at the entrance to their hives. They found that there was no significant differ...

became stigmatized by particular disease associations born more of cultural prejudice than epidemiological fact, and how they adapted to the prejudice and poverty of the new world often by creating their own health institutions, based on American models but imbued with elements native to their indigenous traditions. Second, it analyses the institutional responses of native-born Americans to imm...

Solitary bees and honey bees from a neighbouring apiary were screened for a broad set of putative pathogens including protists, fungi, spiroplasmas and viruses. Most sampled bees appeared to be infected with multiple parasites. Interestingly, viruses exclusively known from honey bees such as Apis mellifera Filamentous Virus and Varroa destructor Macula-like Virus were also discovered in solitar...
