Cutting balloon septotomy for repair of right common iliac artery aneurysm in the setting of type B aortic dissection.

We report a case of using cutting balloon septotomy for a 5-cm right common iliac artery aneurysm repair in a patient with a chronic type B aortic dissection after open repair 10 years before. This technique uses intravenous ultrasound to facilitate deployment of a cutting balloon to shear through the dissection flap, allowing for optimization of the landing zone for endovascular repair of a right common iliac artery aneurysm. Various methods are available for performing septotomy, and the use of a cutting balloon is one that helps with stent placement and position.

The region covers 2 protected areas, Serra da Capivara National Park and Serra das Confusões National Park, and surrounding communities. Fecal samples from 64 animals, 42 from domestic swine and 22 from caititu, collected between 1985 and 2013, were analyzed by optical microscopy.

Chewing lice of Procellaria aequinoctialis Linnaeus, 1758 in Brazil with a new host record.

The white-chinned petrel (Procellaria aequinoctialis) is a seabird widely distributed in the circumpolar sub-Antarctic islands and subtropical regions, including Brazilian waters. Among the parasites present on the white-chinned petrel are the chewing lice. This seabird is parasitized by 4 known lice species to date.

Peri-Procedural Management of Hemodynamic Instability in Patients Undergoing Carotid Revascularization.

Acute perioperative changes in arterial pressure occur frequently, particularly in patients with cardiovascular disease or those receiving vasoactive medications, or in relation to certain cardiovascular surgical procedures. Hemodynamic Instability (HI) is common in patients undergoing carotid revascularization because of unique patho-physiological and surgical factors. The operation, by necessity, disrupts the afferent pathway of the baroreflex, which can lead to postendarterectomy HI.

THE CHEWING LICE OF BROWN BOOBY (SULA LEUCOGASTER) IN SOUTHEASTERN BRAZIL.

The brown booby (Sula leucogaster Boddaert, 1783) has a wide geographic distribution, being found throughout the intertropical range except for the west coast of South America. Chewing lice (Phthiraptera: Amblycera and Ischnocera) are ectoparasites commonly found in association with a wide variety of bird species, and extensive infestations can lead to severe itching and irritation that causes skin lesions, damage to the plumage, and abandonment of nests. Sula leucogaster lice have an atypical distribution, not fully following the distribution of their host.

Chewing Lice of Fregata magnificens with First Record of Fregatiella aurifasciata (Phthiraptera: Amblycera) in Brazil.

The genus Fregata includes 5 species, with 3 recorded in Brazil, with Fregata magnificens being the most abundant. However, its ectoparasitic fauna is still little known. This study aimed to evaluate the incidence of ectoparasites of F.

Are immunoenzymatic tests for intestinal protozoans reliable when used on archaeological material?

Intestinal protozoans found in ancient human samples have been studied primarily by microscopy and immunodiagnostic assays. However, such methods are not suitable for the detection of zoonotic genotypes. The objectives of the present study were to utilize immunoenzimatic assays for coproantigen detection of Cryptosporidium sp.

PREVALENCE AND MOLECULAR CHARACTERIZATION OF (FILARIOIDEA: ONCHOCERCIDAE) IN DOGS FROM ENDEMIC AREAS OF RIO DE JANEIRO STATE, BRAZIL.

Canine dirofilariasis is common in Brazil, but molecular diagnosis is rare even though molecular studies increase our knowledge about molecular epidemiology and circulating genotypes from helminths worldwide. This study aims to estimate the prevalence of infection with a modified Knott's test and to perform molecular characterization of (Leidy, 1856) Railliet and Henry, 1911, in dogs from endemic areas of Maricá and Niterói municipalities, Rio de Janeiro State, Brazil. Molecular characterization was performed in 33 blood samples from dogs positive for microfilariae and 4 adult worms obtained from 2 other dogs.

Integrative taxonomy reveals a new species of Dollfusentis (Acanthocephala: Illiosentidae), in Orthopristis ruber (Osteichthyes: Haemulidae) from Rio de Janeiro, Brazil.

The taxonomy of species of Dollfusentis is rather confused due to the overlap of morphological traits. The aim of this study was to follow an integrative taxonomy approach over the acanthocephalans collected from Orthopristis ruber in Brazil. Dollfusentis lenti n.

Increasing the Efficiency of Spontaneous Sedimentation for the Diagnosis of Intestinal Protozoa.

The aim of this study was to evaluate the association between a longer sedimentation time, the reading of a larger number of slides, and the collection of multiple samples on the efficiency of the spontaneous sedimentation technique. Twenty-two patients with a previous parasitological exam positive for intestinal protozoa were recruited to collect new fecal samples (3 samples per patient) before the beginning of antiparasitic treatment. All collected fecal samples were used for spontaneous sedimentation and centrifuge-flotation techniques.

What is known about Tritrichomonas foetus infection in cats?

Tritrichomonas foetus is a parasite that has been definitively identified as an agent of trichomonosis, a disease characterized by chronic diarrhea. T. foetus colonizes portions of the feline large intestine, and manifests as chronic and recurrent diarrhea with mucus and fresh blood, which is often unresponsive to common drugs.

Feline heartworm (Dirofilaria immitis) infection: first case report of serological diagnosis in Brazil, confirmed by molecular assay.

The clinical importance of heartworm infection in cats has indeed increased in recent years. Dirofilaria immitis infection has been reported worldwide in cats and continues to be regularly diagnosed in endemic areas. The diagnosis can be overlooked easily, especially in Brazil, where there is not a specific feline immunodiagnostic test, forcing the veterinarians to use a test made for the canine host.

Methodological innovations for the study of irreplaceable samples reveal giardiasis in extinct animals (Nothrotherium maquinense and Palaeolama maior).

The use of diagnostic methods that prevent irreplaceable samples (from museum collections, archaeological and paleontological samples) of being consumed or that increase their yield is relevant. For museum collections, archaeological and paleontological samples it is essential to conserve samples, subsamples or portions for future research. We are addressing methods for conservation of irreplaceable samples that could be fully consumed.

infection in two domestic cats with chronic diarrhea.

Case Series Summary: Chronic diarrhea is a common and recurring problem in feline medicine. Intestinal trichomonads have been reported as causative agents of diarrhea in cats. While is considered commensal, has been found to cause feline large bowel diarrhea in cats.

Modification of the Alere GIARDIA Ag TEST immunochromatography KIT methodology for its use in frozen fecal sediment of dogs and cats.

Giardia duodenalis is a worldwide intestinal parasite and is one of the most frequent protozoa species infecting dogs and cats. This study aimed to modify the methodology of Alere GIARDIA Ag TEST KIT for its use in frozen fecal sediments with different storage times in a freezer (-20°C), thus expanding the range of use of this methodology. One hundred fecal sediments from dogs (n=50) and cats (n=50) previously examined by optical microscopy for Giardia cysts were selected for this study.

Rupture of a True Profunda Femoris Artery Aneurysm: Two Case Reports and Review of the English Language Literature.

Profunda femoris artery aneurysms (PFAAs) are very rare and easily overlooked because they are located deeply within thigh muscle. PFAAs have a high rate of rupture in comparison with other peripheral arterial aneurysms, resulting in emergency surgical procedures with significant morbidity. PFAA is diagnosed with color arterial Doppler ultrasound, although computed tomography angiography remains the best imaging method to precisely define the exact site and length of arterial involvement.

Seroprevalence of Toxoplasma gondii (Nicole & Manceaux, 1909) and retroviral status of client-owned pet cats (Felis catus, Linnaeus, 1758) in Rio de Janeiro, Brazil.

Cats, as definitive host, play an important role in the transmission of Toxoplasma gondii. This study aimed to establish the seroprevalence of anti-T. gondii immunoglobulins G and M, and determine the frequency of oocysts in the feces of the domestic cat population in Rio de Janeiro, Brazil.

Seroprevalence of Toxoplasma gondii in cats (Felis catus, Linnaeus 1758) living in Lima, Peru.

The aim of this study was to determine the frequency of infection by T. gondii in cats, by examining serum and fecal samples from animals attended at veterinary clinics in the Metropolitan Region of Lima, Peru. We collected and analyzed 154 cat serum samples and 50 fecal samples, regardless of the age, gender or breed.

Ectopic dirofilariosis in two dogs from Rio de Janeiro state, Brazil.

Report of two canine dirofilariosis cases of ectopic location in the state of Rio de Janeiro. This is the first report of erratic migration for this parasitosis in dogs in the state, calling attention to the short period of time between the two cases. The fact that the area is endemic for this parasite, its zoonotic potential and the report of human cases in the state, demonstrates that authorities should be alerted to the control programs of dirofilariosis along with the pathogenic profile of the infections.

The pathology induced in turkeys (Meleagris gallopavo) by two capillariid nematodes, Baruscapillaria obsignata and Eucoleus annulatus is described together with data on prevalences, mean infection and range of worm burdens. B. obsignata occurred with a prevalence of 72.

Macular pigment, photopigments, and melanin: distributions in young subjects determined by four-wavelength reflectometry.

We have developed an objective procedure, using a modified retinal camera, to determine macular pigment (MP) optical density distributions in the human retina. Using two multi-band filters, reflectance maps of the retinas of young subjects (<25 years old) were obtained at 460, 528, 610 and 670 nm, without pupil dilation. The log-transformed maps were combined linearly to yield optical density maps of MP, cone and rod photopigments, and melanin.
