Head lice infestation is associated with limited morbidity but causes a high level of anxiety among parents of school-aged children. Since the 2010 clinical report on head lice was published by the American Academy of Pediatrics, newer medications have been approved for the treatment of head lice. This revised clinical report clarifies current diagnosis and treatment protocols and provides guid...

BACKGROUND Health providers need to know which measures to take and children to prioritize in order to decrease costs associated with head lice infestations. OBJECTIVE Our aim was to determine the most important predictors for head lice and identify the major drivers of an infestation outbreak in a low-prevalence area. METHODS The study was based on three datasets of head lice prevalence (r...

The chewing lice (Phthiraptera) of Columbidae (Columbiformes) from Pakistan are studied. Six species of chewing lice with new host records are recorded and one new species of the genus Colpocephalum is described from Columba livia in the Karachi region. All the columbid chewing lice from Pakistan are keyed out and the new species is illustrated and compared with the closest allied species.

Head lice infestation, or pediculosis capitis, caused by Pediculus humanus capitis, is a common health concern. In the US, where pediculosis capitis is the most prevalent parasitic infestation of children, 6 to 12 million people are affected every year. Pediculosis capitis remains confined to the scalp. Scalp pruritus is the cardinal symptom, although patients with lice can be asymptomatic. Pru...

The relationship between aquaculture and infestations of sea lice on wild sea trout (Salmo trutta) populations is controversial. Although some authors have concluded that there is a link between aquaculture and lice burdens on wild fish, others have questioned this interpretation. Lice levels have been shown to be generally higher on Atlantic salmon farms during the second years of two-year pro...

b ackground: although there are about 520 species of birds in iran, but only some of them have been checked for ectoparasites so far.the aim of this study was to check some more available species of the birds of iran for lice. m ethods: this study was performed between 2008–2010 in northern iran. for this purpose we tried to check some of the wild bird species available and mostly not checked b...

we conducted a study to evaluate efficacy and safety of dimeticone 4%, a lotion with no conventional insecticide activity, to cure lice infection and to prevent spread of infestation/reinfestation by prophylaxis of classmates.the study is carried out between april 2008 and june 2008 in petranova international institute in rome. a total of 131 children, aged 3 to 13 years (median age: 7 years) w...

Large-bodied species of hosts often harbor large-bodied parasites, a pattern known as Harrison's rule. Harrison's rule has been documented for a variety of animal parasites and herbivorous insects, yet the adaptive basis of the body-size correlation is poorly understood. We used phylogenetically independent methods to test for Harrison's rule across a large assemblage of bird lice (Insecta: Pht...

While it is well known that changes in the general processes of molecular evolution have 18 occurred on a variety of timescales, the mechanisms underlying these changes are less well understood. 19 Parasitic lice (“Phthiraptera”) and their close relatives (infraorder Nanopsocetae of the insect order 20 Psocodea) are a group of insects well known for their unusual features of molecular evolution...
