Mast cells (MCs) play pivotal roles in allergic reactions and the host defense against microbial infection through the immunoglobulin E (IgE)-dependent and IgE-independent signaling pathways. MC lines that can be analyzed both in vitro and in vivo would be useful for the study of MC-dependent immune responses. Here we investigated the functional characteristics of a mouse ES cell-derived mast cell-like cell line, MEDMC-BRC6. The cell line expressed FcεRI and c-Kit and showed degranulation and production of inflammatory cytokines and chemokine, including TNF-α, IL-6 and MCP-1, upon crosslinking FcεRI with IgE...

Empiric initial antibiotic therapy of bacterial infections is based primarily upon the susceptibility of the most common causative pathogens. The purpose of this study was to provide susceptibility data on six bacterial species known to cause ear, nose and throat (ENT) infections. A total of 1066 isolates collected during a nationwide laboratory-based surveillance study were analysed. All Streptococcus pyogenes isolates were penicillin (PEN)-susceptible, indicating that natural penicillins can still be recommended as the first-line treatment for group A streptococcal tonsillopharyngitis...

Acute otitis media (AOM) is a rapid-onset infection of the middle ear which results in middle ear pressure (MEP), middle ear effusion (MEE), and structural changes in middle ear tissues. Previous studies from our laboratory have identified that MEP, MEE, and middle ear structural changes are three factors affecting tympanic membrane (TM) mobility and hearing levels (Guan et al., 2014, 2013). Sound energy reflectance or absorbance (EA) is a diagnostic tool increasingly used in clinical settings for the identification of middle ear diseases...

We describe 3 outbreaks of superficial dermatitis caused by bovine herpesvirus 2 (BoHV-2) in dairy breed calves. Clinically, all of the affected calves were 12-26 d of age, had alopecia and crusts on the face and ears, and were non-pruritic and afebrile. Affected animals recovered spontaneously without any treatment within 2-4 wk after onset of clinical signs based on 1 herd with follow up. Histologic examination of all skin crust or tissue samples identified neutrophilic inflammation, mild hyperkeratosis, multinucleate syncytial cells, and intranuclear inclusion bodies in the syncytial cells...

We report a case of methicillin-resistant Staphylococcus aureus (MRSA) otorrhea with impression material of hearing aid in the middle ear. The patient had chronic otitis media in the right ear with sensorineural hearing loss in both ears. The silicone flowed into the middle ear through a tympanic membrane perforation during the process of making an ear mold. Several days after hearing aid fitting, the patient had severe otalgia, intractable otorrhea, aggravated hearing loss, and dizziness. The pus culture and sensitivity test revealed MRSA...

BACKGROUND: Staphylococci are commensals of the mucosal surface and skin of humans and animals, but have been implicated in infections such as otitis externa, pyoderma, urinary tract infections and post-surgical complications. Laboratory records provide useful information to help investigate these infections. Therefore, the objective of this study was to investigate the burdens of these infections and use multinomial regression to examine the associations between various Staphylococcus infections and demographic and temporal factors among dogs admitted to an academic veterinary hospital in South Africa...

Core body temperature (CBT) is an important and commonly used indicator of human health and endurance performance. A rise in baseline CBT can be attributed to an onset of flu, infection or even thermoregulatory failure when it becomes excessive. Sites which have been used for measurement of CBT include the pulmonary artery, the esophagus, the rectum and the tympanic membrane. Among them, the tympanic membrane is an attractive measurement site for CBT due to its unobtrusive nature and ease of measurement facilitated, especially when continuous CBT measurements are needed for monitoring such as during military, occupational and sporting settings...

Extradural hematoma (EDH) in absence of trauma is a rare entity with only few cases reported in literature. The various causes reported include: Vascular malformation of dura, coagulopathies, sinus infection, middle ear or orbital infection, and tumor. Occurrence of spontaneous EDH as a complication of sickle cell disease is even much rarer. We report a case with sickle cell disease who presented with spontaneous extradural and subgaleal hematomas following an episode of vaso-oclusive crisis. He was managed successfully with surgery...

Leptotrombidium scutellare mites, the vector of Orientia tsutsugamushi, have rarely been reported to associate with Rickettsia species. Three hundred nineteen chiggers were collected from the ears of 32 rodents captured in Huangdao District of Qingdao City, China, in October 2015. The chigger samples were tested for Rickettsia, severe fever with thrombocytopenia syndrome virus, and hantavirus by PCR or RT-PCR amplification. All mites were classified morphologically and molecularly as L. scutellare chiggers...

Dorsal augmentation grafts are used to reconstruct and raise the nasal dorsum in patients with dorsal saddling due to trauma, infection, or previous nasal surgery, as well as in patients with a narrow, congenitally low, and/or wide dorsum. Alloplastic implants and various biomaterials are available for grafting, each with advantages and disadvantages. Although autologous septal cartilage is a preferable and often convenient source of cartilage, it is frequently not sufficient for large volume dorsal augmentation, nor is it available in patients who have had septoplasty, infection, previous rhinoplasty with grafting, or significant trauma...

Ramsay-Hunt syndrome (RHS) is a rare complication of herpes zoster in which reactivation of latent varicella zoster virus (VZV) infection occurs in the geniculate ganglion. Major clinical findings are peripheral facial nerve palsy accompanied by ipsilateral ear pain and erythematous vesicular rash on the external ear (herpes zoster oticus) and in the mouth. Thus, diagnosis of RHS is usually clinical. However, auricular herpetic eruption is not always present, making diagnosis more difficult. This report describes a case of RHS with left facial palsy without skin lesions in 60-year-old woman...

Otitis media (OM) is a common pediatric disease and nontypeable Haemophilus influenzae (NTHI) is the predominant pathogen in chronic OM, recurrent OM and OM associated with treatment failure. OM is also a polymicrobial disease, wherein an upper respiratory tract viral infection predisposes to ascension of NTHI from the nasopharynx, the site of colonization, to the normally sterile middle ear, resulting in disease. Using a clinically relevant viral-bacterial co-infection model of NTHI-induced OM, we performed transcutaneous immunization (TCI) via a bandaid delivery system to administer each of three promising NTHI vaccine candidates derived from bacterial adhesive proteins and biofilm mediators: rsPilA, chimV4 and integration host factor...
