The red mite of poultry, Dremanyssus gallinae, is the most important hematophagous ectoparasite of poultry. In this study, pathologic changes of its biting on the poultry skin have been investigated. Thirty-two (Control = 16 and Treatment = 16) four weeks old Ross broilers (308) were infested with the mite on skin of hock joins. Samples were collected after 1, 24, 72 hours and 10 days. The skin...

The associations between oral parafunctions, signs and symptoms of craniomandibular disorders (CMD), race, and sex were analysed in recordings from 203 4-6-year-old African-American and Caucasian children. Significant correlations were found between bruxism, nail biting, thumb sucking and most of the CMD signs and symptoms. There were also significant associations between most of the signs and ...

BACKGROUND To achieve malaria eradication, control efforts have to be sustained even when the incidence of malaria cases becomes low during the dry season. In this work, malaria incidence and its determinants including bed net use were investigated in children of under 5 years of age in 28 villages in southern Benin during the dry season. METHODS AND FINDINGS Mean malaria clinical incidence w...

BACKGROUND & OBJECTIVES The study was aimed at elucidating the prevalence and intensity of Mansonella perstans microfilaraemia in the Emohua Local Government Area, Nigeria, and ascertaining the abundance, circadian, and the annual biting patterns of the Culicoides vector. METHODS Thick smear of 50 µl finger-prick blood stained with Giemsa was examined microscopically in a cross-sectional stud...

It is well known that individuals in the same community can be exposed to a highly variable number of mosquito bites. This heterogeneity in bite exposure has consequences for the control of vector-borne diseases because a few people may be contributing significantly to transmission. However, very few studies measure sources of heterogeneity in a way which is relevant to decision-making. We inve...

OBJECTIVES Self-injury (SI) is defined as a behavioral disturbance consisting of a deliberate harm to one's own body without suicidal intent, it is not uncommon and ranges in severity from simple nail-biting to more extreme forms of self-mutilation. The head neck region may be the target of such lesions. SI is associated with several medical conditions, of which it can represent the first clini...

Bluetongue has only been isolated as yet from species of biting midges of the genus Culicoides, initially from Culicoides pallidipennis in South Africa by du Toit (1944) and then from C. variipennis in the United States of America by Price and Hardy (1954). More recently it has been isolated from C . pallidipennis, C . milnei and C . tororoensis in Kenya (Walker and Davies 1971), and from C. pa...

The term body-focused repetitive behaviors (BFRBs) refers to a group of recurrent, problematic, destructive behaviors directed toward the body, including hair-pulling, skin-picking, and nail-biting. Individuals with BFRBs report diminished control over the behavior and a range of physical and psychological sequelae. Recent research on psychological models for BRFBs has investigated the role of ...

Reports of foreign bodies in the oronasal complex have included bullets, impression materials, teeth, fish bones, needles, plastics, pistachio nuts, earrings, and the traumatic implantation of a toothbrush." These foreign bodies have been found by palpation, direct visualization, or as incidental findings on radiographs. A thorough history may establish an etiology and time frame in which the f...
