The problem of tail biting has probably been around for as long as pigs have been raised indoors. A recent review of the literature cites mention of the problem going back as far as 1896 but reports of tail-biting first appeared in veterinary journals in the 1940's (SchroderPetersen and Simonsen, 2001). While the causes and "remedies" for tail biting are often discussed in veterinary texts, jou...

Onychophagia is defined as chronic nail biting behaviour, which usually starts during childhood. Onychotillomania results from recurrent picking and manicuring of the fingernails and/or toenails, leading to visual shortening and/or estraction of nails. The aim of this study was to assess the prevalence of onychophagia and onychotillomania in young adults, and the comorbidity of these conditions...

Tail biting has several identified feeding-related risk factors. Tail biters are often said to be lighter and thinner than other pigs in the pen, possibly because of nutrition-related problems such as reduced feed intake or inability to use nutrients efficiently. This can lead to an increase in foraging behavior and tail biting. In this study, a total of 55 pigs of different ages were selected ...

Anopheles populations were monitored for one year in 2 neighboring villages in Faiyum Governorate, Egypt, to study factors causing differences in malaria prevalence. Both villages contained the following speciei: Anopheles pharoensis, An. sergentii, An. multicolor and An. tenebrosus. Abundant larval breeding sites in Abheet, the viliage with the higher malaria rate, accounted for the higher adu...

BACKGROUND African malaria vectors bite predominantly indoors at night so sleeping under an Insecticide-Treated Net (ITN) can greatly reduce malaria risk. Behavioural adaptation by mosquitoes to increasing ITN coverage could allow vector mosquitoes to bite outside of peak sleeping hours and undermine efficacy of this key malaria prevention measure. METHODS High coverage with largely untreated...

AIM Nail-biting is one of the most frequent deleterious oral habits in children. It can result in systemic diseases or oral traumatic lesion. This report describes a case of gingival abscess in a child due to a fingernail-biting habit. CASE DESCRIPTION A 5-year, 6-month-old female presented gingival swelling and fistula in the primary maxillary left central and right lateral incisors as an un...
