BACKGROUND Farmworkers are at high-risk for tick bites, which potentially transmit various tick-borne diseases. Previous studies show that personal prevention against tick bites is key, and certain factors namely, knowledge, experience of tick bites, and health beliefs influence compliance with tick bites preventive behaviour. This study aimed to assess these factors and their associations with...

This study correlated maximum bite force and masticatory muscle electromyography (EMG) activity with craniofacial morphology and mechanical advantage of children with vertical growth patterns. From lateral cephalograms of 30 females and 17 males (9.3 +/- 3.6 years of age), 13 morphological and eight biomechanical measurements were recorded. Two maximum bite forces and 12 submaximal bite forces ...

Recessive dystrophic epidermolysis bullosa of Hallopeau-Siemens (RDEB-HS) is a rare genetic disorder characterized by trauma-induced blisters, milia, acral pseudosyndactyly, and scarring. RDEB-HS patients present with a distinct pattern of oral involvement consisting of microstomia, ankyloglossia, vestibule obliteration and dental caries. In this review, we describe the orodental manifestations...

an ideal orthodontic force system should exert continuous light force. thus, many efforts have been made to improve the memory characteristics of elastomeric chains. the aim of this study was to compare elastomeric chains (ecs) claimed by their manufacturers to offer high memory with traditional ones according to their force-extension diagrams.in this in-vitro study, ecs were divided into six g...

i read with great interest the case report titled “periumbilical pain with radiation to both legs following tarantula bite; a case report” published in emergency journal. tarantula spiders are not medically important except for some very limited species, which do not exist in iran. solifugae -or rotails as they are called in iran- are in fact another group of animals also called camel spiders (...

Snake bite is a signi® cant cause of morbidity and mortality in many parts of the world (Warrell, 1996). The annual incidence of snake bite in KwaZulu-Natal, South Africa, estimated at 81/100 000 (Wilkinson, 1994), is relatively high because the population is mostly rural and the number of snakes resident in the area is large (Branch, 1990). An important determinant of the morbidity and mortali...

Grazing behavior exhibited by different biological types (breed groups) of lactating beef cows was evaluated during the summers of 1985 (Trial 1) and 1986 (Trial 2). Animals grazed native Montana foothill grassland. In Trial 1, breed groups consisted of Hereford (HH), 50% Angus-50% Hereford (AH), 50% Simmental-50% Hereford (SH), and 75% Simmental-25% Hereford (3S1H) with six cows per breed grou...

OBJECTIVE To compare the cephalometric and intraoral characteristics between Long Face pattern and Pattern I patients, besides evaluating associations between subjective facial patterns, cephalometric facial patterns and the intraoral characteristics. METHODS Through evaluation of frontal and right side extraoral photographs, three previously calibrated and experienced examiners selected 30 L...
