The prevalence rate of chronic suppurative otitis media is high and its treatment continues to be a challenge for the otorhinolaryngologists. Due to middle ear infection, there may be pain, hearing loss and spontaneous rupture of the eardrum which results in perforation. Infections can cause a hole in the eardrum as a side effect of otitis media. The patients suffering from ear perforation or having a hole in eardrum require preventing entry of water in the ear. This article describes the development of ear cap using additive manufacturing and TRIZ (a collaborative tool) to prevent the entry of water in the ear during chronic otitis media...

Isolated invasive Mucormycosis of the parotid gland is rarely reported in the literature (1). Mucormycosis most commonly manifests as rhino-oculocerebral and pulmonary infections in the patients with altered immunity (uncontrolled Diabetes mellitus, recipients of immunosupressive therapy and underlying hematological malignancies) (2). Rarely, it causes infection in the immunocompetent individuals (3) with the involvement of unusual sites like gastrointestinal tract, ear, soft tissue and skin (4, 5).

Vesicular stomatitis (VS) is caused by a contagious rhabdovirus that affects horses, cattle, and swine. Clinical signs of vesicular stomatitis virus (VSV) infection in pigs and cattle are indistinguishable from foot-and-mouth disease (FMD), a foreign animal disease and reportable disease in the United States (Rodriguez et al., 2000). A VS epidemic occurred in the Rocky Mountain region in 2014-15. A study was conducted in Colorado to evaluate horse- and management-level factors associated with VS. For a horse to be considered a clinical VS horse, there were two requirements...

Bovine respiratory disease complex is a major cause of illness in dairy calves. The diagnosis of active infection of the lower respiratory tract is challenging on daily basis in the absence of accurate clinical signs. Clinical scoring systems such as the Californian scoring system, are appealing but were developed without considering the imperfection of reference standard tests used for case definition. This study used a Bayesian latent class model to update Californian prediction rules. The results of clinical examination and ultrasound findings of 608 preweaned dairy calves were used...

Otitis media (OM) is a common ear infection and a leading cause of conductive hearing loss in the pediatric population. Current technologies such as otoscopy, pneumatic otoscopy, tympanometry, and acoustic reflectometry are used to diagnose OM, which can reasonably diagnose the infection with a sensitivity and specificity of 50-90% and 60-90%, respectively. However, these techniques provide limited information about the physical architecture of the tympanic membrane (TM), or what may lie behind it. Here, we report the detection of nanometer-scale structural changes of the TM using nano-sensitive optical coherence tomography (nsOCT)...
