Hematologic abnormalities and flow cytometric immunophenotyping results in dogs with hematopoietic neoplasia: 210 cases (2002-2006).

Background: Growing interest in veterinary oncohematology has facilitated the recent development and advancement of new techniques, such as flow cytometry, for immunophenotyping hematopoietic neoplasia in animals.

Objective: The aim of this retrospective study was to characterize hematologic abnormalities and flow cytometric immunophenotyping (FCI) results in cases of hematopoietic neoplasia in dogs.

Methods: Signalment, CBC data, and FCI results were obtained for 210 dogs with blood samples submitted to our laboratory.

Congenital heart disease in boxer dogs: results of 6 years of breed screening.

The aim of this study was to analyse the results of 6years (1999-2004) of mandatory breed screening for congenital heart disease in Boxer dogs using physical examination and echocardiography. Records of 1283 Boxers were reviewed and 165 dogs (12.86%) were found to be affected by heart disease, with aortic and pulmonic stenosis being the most frequent cardiac lesions.

Analysis of the International Classification of Headache Disorders for diagnosis of migraine and tension-type headache in children.

In 2004, the revised International Classification of Headache Disorders (ICHD-II) was published. This study evaluates: (1) the results obtained from applying ICHD-II to children with primary headaches to distinguish between migraine without aura (MO) and tension-type headache (TTH); and (2) the results obtained from introducing modifications of the classification criteria for MO as suggested by various authors. There were 200 participants (93 males, 107 females; age range 3-17 y, mean 9 y 8 mo [SD 2 y 7 mo]).

Development of visual perception and attention, assessed by backward masking and application in children with epilepsy.

Visual masking assesses visual perception and attention; it occurs when a visual stimulus (mask) interferes with the perception of a stimulus that the participant is trying to identify (target). A backward masking study (target presented before mask) was performed on 662 children without disabilities (338 females), aged between 6 and 17 years, in order to evaluate if performance varies with age. In the masking procedure 10 letters were presented through a tachistoscope as target stimuli.
