Treatment of mycotic rhinitis caused by aspergillus fumigatus in a quarter horse mare using topical clotrimazole and oral potassium iodide.

Fungal rhinitis in horses is rare, although severe, due to the progressive nasal obstruction. Aspergillus is one of the fungi most often involved in these cases. A 7-year-old Quarter Horse mare weighing 325 kg was admitted with a history of recurrent nasal discharge and bleeding, foul smell, reluctance to exercise, and abortion.

Atypical angiofibroma in a patient with compromised general health: A case report.

Introduction: The nasopharyngeal angiofibroma (NA) is a benign tumor that originates from the pterygopalatine fossa and extends to the adjacent anatomical structures and affects frequently young individuals. The basic treatment for NA is surgical resection, but in some cases the tumor is surgically inaccessible.

Case Presentation: We describe the case of a 45-year-old male with respiratory difficulty after the appearance of a soft palate lesion.

Clostridioides difficile infection in dogs with chronic-recurring diarrhea responsive to dietary changes.

Five dogs with chronic-recurring diarrhea were positive for Clostridioides difficile infection (CDI), but were unresponsive to treatment with metronidazole. One of these animals was subjected to a colonoscopy, which revealed eosinophilic infiltration of the colon. All five animals completely recovered after dietary changes.

A scientific survey on 1550 cases of oral lesions diagnosed in a Brazilian referral center.

The present study aimed to perform an epidemiological survey on the prevalence rate of oral lesions diagnosed in a referral center in Brazil and to establish association between the lesions and the age and gender of the affected patients. This analytical observational study analyzed 3521 medical records of anatomopathological exams of the Pathological Anatomy and Cytopathology Laboratory of the Cancer Hospital of the state of Mato Grosso (Brazil), from December 2011 to September 2015. A total of 1550 relevant medical records was detected.

Removal of Multiple Keratocystic Odontogenic Tumors in a Nonsyndromic Patient.

Multiple keratocystic odontogenic tumors are one of the key features of Gorlin-Goltz syndrome. A 15-year-old nonsyndromic female child presented with multiple keratocystic odontogenic tumors. The presence of the tumors was observed in immunological examinations.

Reduced chromatin acetylation of malignant salivary gland tumors correlates with enhanced proliferation.

Background: Epigenetic changes refer to any heritable modification in gene expression independent of alterations in the DNA sequence. Currently, it is well established that epigenetics represents a crucial player for tumor development. Nevertheless, the epigenetic mechanisms involved in the development and progression of salivary gland tumors (SGTs) remain poorly understood.

Lipoma of the Palate: An Uncommon Finding.

Background: Lipoma is a benign neoplasm originated from adipose cells circumscribed by connective tissue. This neoplasm represents about 1% to 4.4% of all oral benign tumors and it is rarely located in the palate area.

Clinicopathological analysis of salivary gland tumors over a 15-year period.

Salivary gland tumors (SGT) are rare neoplasms that generate interest due to their histopathological diversity and clinical behavior. The aims of the present study were to investigate clinicopathological aspects of SGTs diagnosed at a tertiary health center and compare the findings with epidemiological data from different geographic locations. Cases of tumor in the head and neck region at a single health center in the period between 1995 and 2010 were reviewed.

Immunoprofile of c-MET/PI3K signaling in human salivary gland tumors.

Objective: The aim of this study was to analyze the expression pattern of proteins in the HGF/c-MET/PI3K signaling pathway in salivary gland tumors (SGTs) and to correlate the findings with the proliferative index and clinical parameters.

Study Design: We assembled tissue microarrays (TMAs) of 108 cases of SGTs, including 69 cases of pleomorphic adenoma (PA), 24 cases of adenoid cystic carcinoma (AdCC), and 15 cases of mucoepidermoid carcinoma (MEC). An immunohistochemical analysis of hepatocyte growth factor (HGF), MET phosphorylation (p-MET), protein kinase B (AKT) phosphorylation (p-AKT), and Ki-67 proteins was performed.

The first clinical and laboratory evidence of co-infection by Anaplasma phagocytophilum and Ehrlichia canis in a Brazilian dog.

Information on Anaplasma phagocytophilum in Brazil is very restricted. The aim of this study was to report clinical, parasitological, hematological and molecular evidence of a natural A. phagocytophilum infection of an urban Brazilian dog.

Ki-67, TGF-β1, and elastin content are significantly altered in lip carcinogenesis.

Epithelial changes observed in actinic cheilitis (AC) and lower lip squamous cell carcinoma (LLSCC) have been studied using different markers in order to observe diagnostic and prognostic factors for both lesions. The aim of the present study was to analyze Ki-67, TGF-β1, and elastin content in AC and LLSCC to determine the possible role of these proteins in lip carcinogenesis. Medical records of 29 cases of AC and 53 cases of LLSCC were analyzed.
