Veterinary vaccine development has several similarities with human vaccine development to improve the overall health and well-being of species. However, veterinary goals lean more toward feasible large-scale administration methods and low cost to high benefit immunization. Since the respiratory mucosa is easily accessible and most infectious agents begin their infection cycle at the mucosa, immunization through the respiratory route has been a highly attractive vaccine delivery strategy against infectious diseases...

Neuroendocrine neoplasms (NENs) of the head and neck are a rare group of heterogeneous epithelial neoplastic proliferations arising in virtually all of the different organs of this region, particularly in the nasal cavity, the paranasal sinuses, the nasopharynx, the larynx, the salivary glands, and the middle ear. They encompass a wide spectrum of entities ranging from very indolent neuroendocrine tumors to highly aggressive neuroendocrine carcinomas. They may represent a challenge for radiologists, oncologists, and pathologists and a correct diagnosis is crucial for the management of patients...

Leukotoxin producing (lkt+) members of Pasteurellaceae, particularly Mannheimia haemolytica and Bibersteinia trehalosi are important pathogens of pneumonia in bighorn sheep (BHS; Ovis canadensis), causing fatal disease. Predisposing or concurrent infection with Mycoplasma ovipneumoniae enhances the severity of the disease, resulting in increased morbidity and mortality. Several studies have investigated the effectiveness of vaccines against lkt+ members of Pasteurellaceae in preventing fatal pneumonia in BHS...

Nasal columella defects can significantly impair aesthetic appearance. Columella reconstruction can be very challenging for surgeons, especially if due to cocaine abuse. The case of a 32-year-old male patient with subtotal columellar necrosis secondary to cocaine abuse is presented. An inferiorly based philtral advancement flap was performed to cover the defect. Aesthetic outcome was the primary goal of surgery. Reconstruction led to good aesthetic and functional results.

Prostaglandin D2 (PGD2) released by degranulating mast cells is believed to play a key role in orchestrating mechanisms of inflammation in allergies and asthma. The biological effects of PGD2 are mediated by D-prostanoid (DP1), CRTH2 (DP2), and thromboxane prostanoid (TP) receptors. The CRTH2 receptor is involved in induction of migration and activation of T helper type 2 (Th2) lymphocytes, eosinophils, and basophils; up-regulation of adhesion molecules; and promotion of pro-inflammatory Th2-type cytokines (interleukin [IL]-4, 5, 13), whereas the DP receptor is associated with relaxation of smooth muscles, vasodilation, inhibition of cell migration, and apoptosis of eosinophils...

Epstein-Barr virus (human herpesvirus-4) is very common virus that can be detected in more than 95% of the human population. Most people are asymptomatic and live their entire lives in a chronically infected state (IgG positive). However, in some populations, the Epstein-Barr virus (EBV) has been involved in the occurrence of a wide range of B-cell lymphoproliferative disorders (LPDs), including Burkitt lymphoma, classic Hodgkin's lymphoma, and immune-deficiency associated LPDs (post-transplant and human immunodeficiency virus-associated LPDs)...

PURPOSE OF REVIEW: To review current surgical practices of lower eyelid reconstruction with a focus on recent studies. RECENT FINDINGS: Combination techniques and new flap techniques offer efficacy comparable with existing reconstructive approaches, with the advantage of less local trauma. Inappropriate handling of posterior lamellar grafts, such as kerfing, may predispose to graft failures. Modified Hughes procedure is a favorable choice for large lower eyelid reconstruction; however, it requires temporary eye closure...

Phosphaturic mesenchymal tumor (PMT) is a rare mesenchymal neoplasm associated with tumor-induced osteomalacia (TIO) and elevated serum FGF-23. Common in extremities, PMT rarely occurs in sinonasal region. We report a series of sinonasal PMT diagnosed at our institute over a 6-year period. Six cases of sinonasal PMT were identified during this period, of which five presented with features of TIO. Median age of patients was 45.5 years. All six tumors were composed of stellate to spindled cells, with prominent staghorn vasculature in four cases...

Juvenile nasopharyngeal angiofibroma is tumour almost exclusively seen in adolescent males, constituting less than 1% of all neoplasms in head and neck. They are benign and locally spreading and are highly vascular in nature and thus prove to be a surgical challenge because of its complex anatomical location. Here, we present a case report of a 18-year-old male presenting with a mass in his left nasal cavity, with recurrent epistaxis and nasal obstruction. Computed tomography imaging revealed a non-encapsulated lobulated heterogeneous mass lesion in the naso-pharynx and left posterior choana of the nasal cavity, extending to pterygopalatine and infratemporal fossa, masseter space of left side...
