BACKGROUND: Intra-operative quantification of the ossicle mobility could provide valuable feedback for the current status of the patient's conductive hearing. However, current methods for evaluation of middle ear mobility are mostly limited to the surgeon's subjective impression through manual palpation of the ossicles. This study investigates how middle ear transfer function is affected by stapes quasi-static stiffness of the ossicular chain. The stiffness of the middle ear is induced by a) using a novel fiber-optic 3-axis force sensor to quantify the quasi-static stiffness of the middle ear, and b) by artificial reduction of stapes mobility due to drying of the middle ear...

Recently, the number of clinical reports of growing pigs showing neurological signs possibly related to viral infections has increased. The objective of this report was to describe two outbreaks of an atypical condition observed in 6- to 7-week-old pigs with a morbidity of 20% and a fatality rate of 60% in two unrelated farms of the same company. During the acute phase of the disease, fever, sudden death, neurological signs, ear necrosis and occasional corneal opacity were observed. Histopathological examination revealed interstitial pneumonia, lymphoid depletion and lymphocytic vasculitis in different organs and mild polioencephalomyelitis suggesting a potential viral infection...

Otitis media (OM) is a common condition in Australia. It represents a spectrum of diseases from otitis media with effusion (OME) to chronic suppurative otitis media. For all the OM diagnoses, Australian Indigenous children have higher rates of early onset, severe and persistent disease. OME is the most common form of OM and often occurs after an upper respiratory tract infection. It can be difficult to diagnose (and often goes unrecognised). Hearing loss is the most important complication. The middle-ear effusion impedes the movement of the tympanic membrane and causes a conductive hearing loss of around 25 dB...

While the usage of illicit drugs in itself carries significant health risks and associated toxicities, drugs that are adulterated to give them volume, alter their psychogenic properties, and make them cheaper to produce are to be considered even more dangerous. Cocaine is one of them, and it is now most commonly being adulterated with levamisole. We report a case of a 37-year-old female with the chief complaint of painful skin lesions and wounds on both of her upper and lower extremities for three weeks duration...

OBJECTIVE: To study whether the contraction evoked by muscle percussion stems from the excitation of the muscle or of the nerve and to discuss the changes of this response in neuromuscular disorders. METHODS: In 30 neurologically healthy patients undergoing surgery (for ear, nose, or throat problems unrelated to the study) under general anesthesia with propofol and sufentanil we measured with an electrogoniometer the maximal dorsiflexion of the ankle evoked by reflex hammer percussion of the tibialis anterior muscle before and under neuromuscular junction blockade with rocuronium bromide...

BACKGROUND: Ear symptoms are common among patients presenting to a rhinology clinic. Validated inventories are available for patient quality-of-life in sinonasal disease and Eustachian tube dysfunction (ETD). This study sought to determine the extent of ETD symptoms, using validated metrics, in a large population of patients presenting to a tertiary rhinology clinic. METHODS: Seven-item Eustachian Tube Dysfunction Questionnaires (ETDQ-7) and 22-item Sino-Nasal Outcome Tests (SNOT-22) were prospectively collected from 492 patients treated in a tertiary rhinology clinic...

Sutures are one of the most widely used devices for adhering separated tissues after injury or surgery. However, most sutures require knotting, which can create a risk of inflammation, and can act as mechanically weak points that often result in breakage and slipping. Here, an anchoring suture is presented with a design that facilitates its propagation parallel to the suturing direction, while maximizing its resistive force against the opposite direction of external force to lock its position in tissues. Different microstructures of suture anchors are systematically designed using orthogonal arrays, and selected based on shape factors associated with mechanical strength...

The inner ears of all vertebrates are designed to perceive auditory and vestibular inputs. Although a tremendous diversity in the inner ear can be found even among bony fishes, the morphologies of the utricle and of the semicircular canals are rather conservative among vertebrates. Fish show kinetoses under reduced gravity (spinning movements and looping responses) and are regarded model organisms concerning the performance of the otolithic organs. Otoliths can be analysed easily because they are compact, in contrast to the otoconial masses of other vertebrates...

Carcinoma of the external and middle ear is a very rare disease. Despite the various treatment modalities available, its prognosis is still poor. We aimed to analyze the treatment modalities, outcomes, and validity of surgical approaches, especially in advanced tumors in the ear. Twenty-five patients with carcinoma of the external and middle ear were retrospectively analyzed. The modified Pittsburgh staging system was used for staging of the patients. Overall and disease-free survival was estimated using of Kaplan-Meier method...

Pakistan has a high prevalence of hepatitis C virus (HCV) infection, estimated at 4.9% (2,290/46,843) in the 2007 national HCV seroprevalence survey. We used data from this survey to assess the importance of risk factor associations with HCV prevalence in Pakistan. Exposures were grouped as community (going to the barbers, sharing smoking equipment, having an ear/nose piercing, tattoo, or acupuncture), healthcare (ever having hemodialysis, blood transfusion, or ≥ 5 injections in the last year), demographic (marital status and age), and socio-economic (illiterate or laborer)...

BACKGROUND: Chlorophylls (Chls) are magnesium-containing tetrapyrrole macromolecules responsible for the green color in plants. The Chl metabolic pathway has been intensively studied and nearly all the enzymes involved in the pathway have been identified and characterized. Synthesis and activity of these enzymes are tightly regulated in tissue- and developmental stage-specific manners. Leaves contain substantial amounts of Chls because Chls are indispensable for photosynthesis. In contrast, petals generally contain only trace amounts of Chls, which if present would mask the bright petal color...

BACKGROUND: Curly horses present a variety of curl phenotypes that are associated with various degrees of curliness of coat, mane, tail and ear hairs. Their origin is still a matter of debate and several genetic hypotheses have been formulated to explain the diversity in phenotype, including the combination of autosomal dominant and recessive alleles. Our purpose was to map the autosomal dominant curly hair locus and identify the causal variant using genome-wide association study (GWAS) and whole-genome sequencing approaches...

The present report concerns two experiments extending to unimodal priming the cross-modal priming effects observed with auditory emotions by Harding and Voyer [(2016). Laterality effects in cross-modal affective priming. Laterality: Asymmetries of Body, Brain and Cognition, 21, 585-605]. Experiment 1 used binaural targets to establish the presence of the priming effect and Experiment 2 used dichotically presented targets to examine auditory asymmetries. In Experiment 1, 82 university students completed a task in which binaural targets consisting of one of 4 English words inflected in one of 4 emotional tones were preceded by binaural primes consisting of one of 4 Mandarin words pronounced in the same (congruent) or different (incongruent) emotional tones...

Biallelic HMX1 mutations cause a very rare autosomal recessive genetic disorder termed as oculoauricular syndrome (OAS) because it is characterized only by the combination of eye and ear anomalies. We identified a new family bringing to three the total families reported with this disorder. Our proband presented with anteriorly protruded ears and malformed ear pinnae in association with microphthalmia, congenital cataract, microcornea, and iris and optic disc colobomata. Additionally, he had high and broad forehead with asymmetry giving a recognizable facial gestalt...
