Dystocia and cesarean section in a free-ranging ocelot () after traumatic spinal cord injury resulting from dog () attack.

Background: breeding programs are essential to establish genetic resource banks and produce offspring to strengthen the conservation of endangered species. However, many programs fail to maintain viable populations due to reproductive problems, including dystocia in pregnant females. Dystocia encompasses different emergency obstetric situations for the lives of dams and fetuses that require urgent intervention.

Histological and microbiological evaluation of surgical wound closure in mouse skin with cyanoacrylate (Histoacryl®) in comparison to poliglecaprone (Monocryl®) traditional suture.

Incisional wound closure is a key surgical step to facilitate tissue healing, reduce the risk of infection and obtain esthetic and functional recovery. Cyanoacrylates such as Histoacryl® have become a popular choice in surgical veterinary practice. However, how Histoacryl® is affecting tissue regeneration and bacterial load in the wound in comparison to poliglecaprone (Monocryl®) traditional suture methods remains to be determined.

Transorbital transnasal endoscopic combined approach to the anterior and middle skull base: a laboratory investigation.

Orbital approaches provide significant trajectory to the skull base and are used with differently designed pathways. The aim of this study is to investigate the feasibility of a combined transorbital and transnasal approach to the anterior and middle cranial fossa. Cadaveric dissection of five silicon-injected heads was used.

Patient-related and ENT-related predictive factors based on the pain experienced during flexible nasendoscopy.

Objectives/hypothesis: The objective was to explore the role of specific patient-related and operator-related factors in pain perception during flexible laryngoscopy, which is one of the most common ENT procedures.

Study Design: Monocentric, randomized, individual prospective study.

Methods: A total of 532 patients (145 men and 387 women), without any relevant ENT diseases, underwent laryngoscopy performed by otolaryngologists with various degrees of experience.

Transoral robotic resection of an ectopic tongue-base thyroid gland.

Lingual thyroid is an uncommon condition, often asymptomatic. Given its benign nature, every treatment should be well balanced in terms of advantages and local morbidity. When a treatment is planned, medical and surgical therapy should be weighed against each other.

High-intensity focused ultrasound as an alternative to the surgical approach in primary hyperparathyroidism: a preliminary experience.

Background: Surgery is the therapy of choice in primary hyperparathyroidism (PHPT), although other less invasive techniques have been used in the attempt to cure the disease. Recently, high-intensity focused ultrasound (HIFU), a totally non-invasive technique, has become available to cure solid tumors.

Aim: The aim of this pilot study has been to assess the safety and efficacy of HIFU in symptomatic patients with PHPT.

Respiratory retraining therapy in long-term treatment of paradoxical vocal fold dysfunction.

Objectives: Paradoxical vocal fold dysfunction (PVFD) is a disorder in the larynx featuring involuntary adduction of the vocal folds during the inspiratory phase of breathing. The symptoms include acute episodes of dyspnea and bouts of coughing. To date, there is no universally acknowledged treatment for PVFD, though respiratory retraining therapy is the treatment of choice.

The role of high-resolution magnetic resonance in atypical and intractable benign paroxysmal positional vertigo: our preliminary experience.

Background: The diagnosis of benign paroxysmal positional vertigo (BPPV) is easy when typical nystagmus is present. However, diagnostic doubts arise when faced with cases presenting atypical features of the positional paroxysmal nystagmus as well as the clinical course and disease evolution.

Methods: A morphological evaluation of inner ear structures via high-resolution magnetic resonance (HR-MR) studies has been performed in 2 patients that did not respond to traditional therapeutic manoeuvres.

Cranio-cervical necrotizing fascitiis: case report and review of the literature.

Necrotising fascitiis is a rapidly progressive bacterial infection of the soft tissues and generally attacks the walls of the abdomen, the perineum, the limbs or, to a lesser degree, the cranio-cervical area. In the latter region, the infection involves the soft tissues of the neck, in a more or less extensive manner, and causes diffuse necrosis. Crepitation, areas with linear infiltration and others with fluctuation are detected on manual examination.

Antibodies to inner ear antigens in Meniere's disease.

Meniere's disease (MD) is an idiopathic inner ear disorder characterized by fluctuating hearing loss, episodic vertigo and tinnitus. Its aetiology is unknown, although there is growing evidence that autoimmunity may be involved in its development. Using the Western blot immunoassay, we examined the reactivity to bovine inner ear antigens of sera from a series of MD patients who had previously been extensively studied for the presence of antibodies to collagens and membrane proteins.

Scala vestibuli cochlear implantation in patients with partially ossified cochleas.

Partial cochlear obstruction is a relatively common finding in candidates for cochlear implants and frequently involves the inferior segment of the scala tympani in the basal turn of the cochlea. In such patients, the scala vestibuli is often patent and offers an alternative site for implantation. The current report describes two patients with such partial obstruction of the inferior segment of the basal cochlear turn, caused in one case by systemic vasculitis (Takayasu's disease) and in the other by obliterative otosclerosis.

[Therapeutic maneuvers in the treatment of paroxysmal positional vertigo: can they indicate a central genesis?].

Typical Paroxysmal Positional Nystagmus (PPNy) is a highly specific clinical finding that indicates the existence of a specific peripheral lesion: Paroxysmal Positional Vertigo (PPV). However, besides this typical nystagmus of high topodiagnostic significance, atypical PPNy's are also frequently found. Such atypical findings can lead one to suspect a central vestibular system pathology and often require additional diagnostic testing.

[Progressive sensorineural hearing loss: metabolic, hormonal and vascular etiology].

Metabolic, hormonal and vascular disorders are considered to cause hearing dysfunction such as progressive sensorineural hearing loss (PSNHL). The diseases most commonly associated with PSNHL are diabetes mellitus, congenital and acquired hypothyroidism, chronic renal failure, chronic labyrinthine ischemia determined by non-hematologic factors (tissue perfusion pressure, blood vessel diameter) or by hematologic factors (blood viscosity and/or rigidity of the red blood cells). In this study a review of data on the relationship between these clinical disorders and the presence and deterioration of the hearing function was carried out.

Herpes zoster oticus: correlations between clinical and MRI findings.

Many gadolinium-enhanced magnetic resonance imaging (MRI) studies focusing on the anatomy and pathology of the 7th cranial nerve have already been published. However, only scattered cases of herpes zoster oticus (HZO) have been described and only the MRI appearance of the soft temporal bone structures has been reported. Enhanced MRI was performed in 4 patients with HZO observed at the Department of Otorhinolaryngology of the University of Pisa.

Audiovestibular involvement in systemic sclerosis.

In order to evaluate the nature and association of audiovestibular disturbances and systemic sclerosis (SSC), 37 unselected SSC patients were studied with a detailed audiological and vestibular examination since November, 1987. Pure-tone audiometry, speech audiometry, impedance audiometry, brainstem response audiometry and vestibular function using electronystagmographic recording were performed. We found a rather frequent audiovestibular involvement (41%).

Hibernoma of the larynx. Review of the literature and a new case.

Hibernoma is a rare, benign, soft-tissue tumour composed of cells similar to those of brown adipose tissue. Only seven cases in the cervical area have been reported and none in the larynx. A case of hibernoma of the pre-epiglottic area is presented and the histological, histogenetical and clinical features are discussed.

Lethal midline granuloma: a case of Ki-1 lymphoma.

Lethal midline granuloma syndrome (LMG) is the clinical term generally used to describe a rare clinical entity of unknown cause characterized by a progressive and often fatal ulceration and destruction of the upper airway involving the nose, the paranasal sinuses and the soft tissues of the face. The following histopathologic entities have always been grouped under the term LMG: Wegener granulomatosis (WG), non-Hodgkin lymphoma, polymorphic reticulosis (PR) and idiopathic midline destructive disease (IMDD). Today in order to begin an adequate therapy a differential diagnosis is necessary.

[Bovine costal cartilage as material for otologic reconstruction: anatomo-functional results].

The Authors present their experience in using bovine cartilage as otological material reconstruction. Cartilage of the ribs is to collect from selected bred cattle and is first placed in an antibiotic solution for 3 days and then in a 70% ethyl alcohol in which it is stored for 20 days before being utilized. One hundred-nineteen cartilage heterografts have been implanted in the middle ear since January 1989.

[Lyophilized bone homografts in reconstructive surgery of the middle ear].

The authors present their experience with stored lyophilized bone allografts utilized in middle ear reconstructive surgery. The implants were cut from the cortical substance of the long bone in subjects deceased. A demineralization in 0.

[Histological and ultrastructural aspects of oto-mastoid cholesteatoma in children].

Cholesteatomas were intraoperatively removed from subjects under 14 years of age presenting widespread cholesteatoma with bone erosion. The samples were studied under light and transmission electron microscopy in order to consider the features of inflammation and bone erosion. The results showed that the perimatrix of cholesteatoma in children is rich in mononuclear inflammatory elements and generally presents the features of chronic, as well as acute, inflammation.
