Protocol for static posturography with dynamic tests in individuals without vestibular complaints using the Horus system.

Purpose: To propose a protocol for investigating the body balance and determining reference values in different age groups and gender, using the methodology of static posturography with dynamic tests, in low-cost Brazilian equipment for diagnosing balance.

Methods: The objectives of this study aimed to propose a protocol for investigating the body balance and determining reference values in different age groups and gender, using the methodology of static posturography with dynamic tests, in new low-cost Brazilian equipment for diagnosing balance. Method: 297 healthy volunteers, between 20 and 89 years old, without vestibular complaints, were divided into six groups according to age group and gender.

Reversal of paradoxical stimulation (false inversion) in perforated tympanic membranes by increasing the time of warm stimulation, evidenced by a physical model.

Objective: To measure the time required in patients with tympanic perforation to reverse paradoxical stimulation (reverse pseudo-nystagmus) and to create a physical model of the process.

Method: An analytical, observational, cross-sectional study with vestibular evaluation (electronystagmography) of 52 individuals with tympanic membrane perforation without otorrhea or concomitant disease. Increased duration of caloric stimulation in the presence of paradoxical stimulation (reverse pseudo-nystagmus) reverses nystagmic responses.

Feasibility of ossicular chain reconstruction with resin cement.

Introduction: Disjunction of ossicular chain is a common finding in middle ear chronic disease. In addition to ossicular interposition, various materials have been used for reconstruction, such as ceramic prostheses, polyethylene, and titanium.

Objective: Because of the high cost of the available options, the authors propose to reconstruct the ossicular chain with resin cement, a material typically used in dental reconstruction and fixation.

Comparative histological study on wound healing on rat's skin treated with Mitomycin C or Clobetasol propionate.

Purpose: To compare histologically the action of Mitomycin C and that of Clobetasol propionate for surgical wound healing in rats.

Methods: A circular skin fragment was surgically removed from 57 Wistar rats. Twenty-two animals were treated with Mitomycin C with topical medication in a single dose, 22 with Clobetasol propionate with a cream medication once a day for 15 days and 13 did not receive any medication.

Hearing loss assessment in primary and secondary acquired cholesteatoma.

Introduction: Acquired middle ear cholesteatoma can be classified as primary or secondary. Although both can result in hearing loss, it is still controversial whether there is an association between the type of cholesteatoma and the degree of hearing loss.

Objective: To analyze the association between hearing loss and the type of acquired cholesteatoma, and the status of the ossicular chain.

[Objective comparison between perforation and hearing loss].

Introduction: There appears to be no relationship between the size of tympanic perforations and hearing loss. Some studies in the literature have assessed this connection, with conflicting data and without proper methodology, especially concerning the measurement of the size of the perforation, which was performed in a subjective manner.

Objective: To evaluate the size of tympanic perforations and to relate them to hearing loss in four different sound frequencies through the use of an objective method.

Comparative assessment between objective and subjective methods in slides stained by immunohistochemistry.

Unlabelled: Objective methods of assessment are often required in scientific studies. Histological tests with immunohistochemical staining can be assessed by photometry.

Objective: To compare this objective method with the subjective evaluation performed by three independent examiners, using slides of acquired middle ear cholesteatomas.

Method for removal of samples of ear canal and tympanic membrane for histologic and immunhistochemical study.

Unlabelled: Temporal bones are valuable resources to study ear diseases. Although there are several methods for removing temporal bones from cadavers, such methods are not usually described in enough details in experimental research papers.

Objectives: To describe a simple and rapid method for ear canal and tympanic membrane removal, and to evaluate its viability for histologic and immunohistochemical studies.

Analysis of histopathological aspects in acquired middle ear cholesteatoma.

Unlabelled: Middle ear cholesteatomas are characterized by the presence of stratified squamous epithelium in this cavity with highly invasive properties causing bone destruction and it may lead to complications.

Aim: To study the histopathological features in acquired cholesteatomas of the middle ear, correlating this data with patient age.

Study Design: clinical and experimental cross-sectional study.

Clinical data and hearing of individuals with Alport syndrome.

Unlabelled: Alport Syndrome (AS) is a hereditary disease, characterized by nephropathy, often times with sensorineural hearing loss and ocular defects.

Aim: to analyze the clinical and hearing information from individuals with AS, more specifically the correlation between renal disorder and hearing loss (HL).

Study Design: clinical prospective with cross-sectional cohort.

Study of wound healing in rats treated with topical and injected mitomycin C.

Objectives: Mitomycin C, a widely used chemotherapeutic drug, has been proposed as a potential adjuvant for the control of scar tissue in surgical wounds because of its capacity to inhibit fibroblast proliferation. The current study used a combination of topical and injected mitomycin C to slow the healing process of surgical wounds in rats.

Methods: An experimental model of surgical wounding at the dorsum of rats was used.

Study of wound healing in rats treated with topical and injected mitomycin-C.

Unlabelled: Experimental study in animals.

Introduction: Mitomycin C has been used as a fibroblasts inhibitor, thus reducing the scaring process in surgical wounds.

Aim: This paper aims at assessing the use of Mitomycin C to reduce the scaring process through its topical use and later injected reinforcements.

Foreign body in the Eustachian tube: case presentation and technique used for removal.

Unlabelled: Foreign bodies of the external ear are very common; the same can not be said about foreign bodies of the middle ear, especially of the Eustachian tube.

Case Presentation: Alcoholic and psychopathic patient presented a foreign body (barbecue wooden stick) purposefully introduced in his middle ear and Eustachian tube during an act of delinquency. The foreign body was stuck in the tube and could not be removed externally.

Diagnosis routine and approach in genetic sensorineural hearing loss.

Aim: To develop a screening in order to determine the more common syndromic and non-syndromic genetic SNHL, considering epidemiological data, information and the development of new technologies; clinical implications and bioethical issues.

Materials And Methods: We reviewed the literature in order to develop a screening that includes: history, patterns of inheritance, physical evaluation, laboratory tests, image studies, multidisciplinary approaches and genetic tests.

Conclusion: The epidemiologic data estimates that at least 50% of prelingual HL can be determined by genetic alterations.

The role of tumor necrosis factor-alpha (TNF-alpha) in bone resorption present in middle ear cholesteatoma.

Unlabelled: Cholesteatoma may cause bone erosion, with high morbidity and mortality rates. Tumor necrosis factor-alpha (TNF-a) is one of the main cytokines involved in this process. Our goal was to evaluate the role of TNF-a in Bone Resorption and its effect on cholesteatoma.

Oral ivermectin for the treatment and prophylaxis of scabies in prison.

Introduction: Oral ivermectin has been widely used to treat various human diseases, such as filariasis, myiasis, larva migrans, strongyloidiasis and scabies (both the common and crusted forms). However, there are only a small number of papers on the effects of this drug for the control of scabies in infested environments. The current study shows the results obtained with the collective treatment of inmates of a public jail.

Clinical and histological healing of surgical wounds treated with mitomycin C.

Objectives/hypothesis: The proven ability of mitomycin C to inhibit fibroblasts in vitro has stimulated its use in research animals and in humans to control healing. The objective of the study was to follow the healing process of surgical wounds in the dorsum of rats treated topically with mitomycin C.

Study Design: Prospective experimental study.
