Clinical Management and Neurosurgical Approach of Pott's Puffy Tumor: A Case Report.

Pott's puffy tumors are assumed to be infrequent concomitant intra- and extracranial abscesses, mainly secondary to complicated frontal sinusitis during infancy. Due to the close proximity to the superior sagittal sinus, there is a risk of developing venous infections, thrombosis, and morbidity. In this case report, we present a case of an 11-year-old girl who presented with headache and face edema.

Melanophoroma in a Lichtenstein's green racer snake.

Melanophoroma is a neoplasm of reptilian pigment cells, considered uncommon and part of a group of neoplasms called chromatophoromas. The objective of this work was to describe a case of melanophoroma in a free-living Lichtenstein's green racer snake (Philodryas olfersii), presenting with an ulcerative nodular neoformation in the integument of the head region. In the neurologic evaluation, a proprioceptive deficit was observed.

Protection against leptospirosis conferred by Mycobacterium bovis BCG expressing antigens from Leptospira interrogans.

Leptospirosis is a zoonotic disease worldwide and caused by the pathogenic spirochetes of the genus Leptospira. Bacterins make up the vaccines used against leptospirosis, but they only succeed in providing short-term and serovar-specific protection. The use of Mycobacterium bovis BCG as a live vaccine vector expressing leptospiral antigens is a promising alternative, particularly due to its adjuvant properties.

Aspergillosis in free-ranging aquatic birds.

Unlabelled: Due to the difficulty in the access to free-ranging birds, data regarding infections in wild avian species is rare compared to captive wild and domestic birds.

Objective: report three cases of section causing fungal disease in free-ranging aquatic birds, with the identification of the causal agent to the species level.

Case Reports: The diagnosis of aspergillosis was performed by macroscopic lesions found during the necropsy and confirmed by culture.

Aspergillosis in albatrosses.

Aspergillosis is a respiratory fungal disease of importance in captive marine birds. The aim of this study was to describe the occurrence of aspergillosis in Thalassarche melanophris during rehabilitation events and to identify the etiological agent. All the albatrosses that were received for rehabilitation and died within a 2-year period were included in the study.

Histomorphometry of the placental vasculature and microcotyledons in Thoroughbred mares with chronic laminitis.

The objective of this study was to assess the placental vasculature and microcotyledons in pregnant mares with chronic laminitis. Twenty-six pregnant mares were enrolled in the study, 13 had chronic laminitis (Laminitis Group) and 13 were healthy mares (Healthy Group). Arterial systolic pressure and heart rate were measured in the last 30 days of gestation.

Maternal Transfer of Bisphenol A During Nursing Causes Sperm Impairment in Male Offspring.

The health effects of environmental chemicals on animals and humans are of growing concern. Human epidemiological and animal study data indicate that reproductive disorders and diseases begin early during prenatal and postnatal development. An increase of human male reproductive disturbance in the past several decades was associated to chemicals called endocrine disruptors (ED).

Evaluation in broilers of the probiotic properties of Pichia pastoris and a recombinant P. pastoris containing the Clostridium perfringens alpha toxin gene.

The probiotic properties of Pichia pastoris and of a recombinant P. pastoris containing the Clostridium perfringens alpha toxin gene were evaluated in broilers. One-day-old chicks randomly divided in four groups were fed with commercial feed devoid of antibacterials.

Epidemiological findings and laboratory evaluation of sporotrichosis: a description of 103 cases in cats and dogs in southern Brazil.

Sporotrichosis is a subcutaneous mycosis, which affects mainly small animals, and is considered an important public health disease. This paper describes the epidemiological and laboratory characteristics of 103 clinical cases of sporotrichosis diagnosed over a 10-year period in southern Brazil. The 92 cats and 11 dogs from eight municipalities in Rio Grande do Sul State developed especially the disseminated cutaneous and fixed cutaneous forms of the disease.

Disease progression of dermatophytic pseudomycetoma in a Persian cat.

Background: Dermatophytic pseudomycetoma is a subcutaneous fungal infection by Microsporum canis.

Aims: This work describes a case of dermatophytic pseudomycetoma in a Persian cat.

Patient And Methods: A 3-year old female Persian cat showing alopecia, scaling and ulcerated nodules throughout the body, with presence of ulcerated nodules with yellow granular discharges on the dorsum, close to the tail.

[Experimental cutaneous sporotrichosis: in vivo evaluation of itraconazole and terbinafine].

The aim of this study was to evaluate the in vivo activity of itraconazole and terbinafine for treating experimental cutaneous sporotrichosis. Eighty Wistar rats were used, divided into four groups (TERB20, TERB30, ITRA and CONT). They were inoculated in the left plantar pad with 0.

Role of melanin in the pathogenesis of cutaneous sporotrichosis.

In this study, we evaluate the clinical, histopathological and ultra structural aspects of the infection by field strain (MEL(+)) and mutated strain (MEL(-)) of Sporothrix schenckii. The development of sporotrichosis at the inoculation sites was similar for both groups of animals after the second week of the experimental period. Statistical differences appeared only at weeks 3 and 5.

Motif search in graphs: application to metabolic networks.

The classic view of metabolism as a collection of metabolic pathways is being questioned with the currently available possibility of studying whole networks. Novel ways of decomposing the network into modules and motifs that could be considered as the building blocks of a network are being suggested. In this work, we introduce a new definition of motif in the context of metabolic networks.

Differences in virulence between isolates of feline Sporotrichosis.

Sporotrichosis is a chronic subcutaneous mycosis caused by Sporothrix schenckii. This work aimed to evaluate the virulence of two different isolates of S. schenckii from cutaneous (CUT) and systemic (SYS) forms of feline sporotrichosis.
