Effects of fungicides on the ultrastructure of the hypopharyngeal glands and the strength of the hives of Apis mellifera Linnaeus, 1758 (Hymenoptera: Apidae).

Several crops of agronomic interest depend on bees' pollination, and Apis mellifera L (Hymanoptera: Apidae) is the most studied direct pollinator. Nevertheless, the use of pesticides in agricultural environments is common, including fungicides. Studies that seek to evaluate the effects of fungicides on the hypopharyngeal glands of bees, the site of royal jelly synthesis, are lacking.

Proteomic profiling of royal jelly produced by Apis mellifera L. exposed to food containing herbicide-based glyphosate.

Royal jelly (RJ) is rich in protective elements associated with collective immune defenses in the hive of Apis mellifera. Exposure of bees to glyphosate-based herbicides causes ultrastructural changes in the hypopharyngeal glands and a reduction in the production of RJ. However, the effects of glyphosate-based herbicides on the protein composition of RJ and consequences for the hive are unknown.

The cost of alkaline solutions in ambulatory hemodialysis: an analysis about wasteful from the processes control.

Introduction: There are few studies about costs of inputs used in hemodialysis and among these expenditures, the compounds that make up the dialysate are one of the values considered as representative of this therapy. However, there aren't costs studies that guiding solutions.

Objective: The objective of this article is discuss whether there is wasteful of alkaline solutions in ambulatory hemodialysis and hence the possibility of reduction in cost from the standardization process simulation of establishment of dialysate flow in periods between shifts in hemodialysis outpatients.

Limits on quality of life in communication after total laryngectomy.

Introduction:  Among people affected by cancer, the impairment of quality of life of people affected by cancer can cause have devastating effects. The self-image of patients after post-laryngectomyzed patients may be find themselves compromised, affecting the quality of life in this population.

Objective:  To characterize quality of life in related to communication in people who have undergone went total laryngectomy surgery.

Graphic angle measure as an electrocochleography evaluation parameter.

Unlabelled: To improve electrocochleography's diagnostic sensitivity in Meniére's disease - new assessment methods are being studied.

Aim: To determine whether or not graphic angle measurement is sensitive and specific to Menière's disease laboratorial diagnosis and if there is an increase in the electrocochleography's sensitivity and specificity when graphic angle measurements are associated with Summating Potential-Action Potential ratio (SP/AP ratio).

Methods: Electrocochleography's was used to analyze 71 ears from 55 subjects: 41 patients with clinical diagnosis of Menière's disease (MD group), and 14 healthy individuals as control (Group C).

Intralesional amphotericin B in a cat with refractory localised sporotrichosis.

The present report concerns a case of sporotrichosis in a 3-year-old male crossbred cat. After 9 months of oral itraconazole (20mg/kg) therapy, all skin lesions had resolved with the exception of a single nodular lesion located on the bridge of the nose. Therefore, a combined therapy that included intralesional (IL) amphotericin B (1mg/kg) was started.

Sudden hearing loss caused by labyrinthine hemorrhage.

Sudden sensorineural hearing loss is relatively frequent. In most cases, the etiology is not discovered. One of the possible causes for sudden deafness is inner labyrinth bleeding, which was difficult to diagnose before the advent of magnetic resonance imaging.

Pediatric otosclerosis: case report and literature review.

Otospongiosis is an osteodystrophy of the temporal bone, characterized by disordered neoformation and deposition of bone, characterized by the presence of a progressive conductive, sensorineural or mixed hearing loss and tinnitus. Typically, otospongiosis presents as a slowly progressive conductive hearing loss in the third to fourth decade of life. Uncommonly children and adolescents may also have conductive or sensorineural hearing loss caused by otosclerosis.

Bilateral inverted papilloma: case report and literature review.

The inverted papilloma is an uncommon unilateral nasosinusal benign tumor. The clinical picture presents nonspecific signs and symptoms, such as unilateral nasal obstruction, anosmia and headache. The diagnosis is established by anamnesis, physical exam, computed tomography and magnetic resonance imaging.

The outcome of patients with Ménières disease.

Unlabelled: Ménière;s disease is a frequent vestibular disease that occurs predominantly in the fourth decade of life. Diagnosis is mostly medical and is based on findings of vertigo, sensorineural hearing loss, tinnitus and aural fullness.

Aim: To study the clinical findings of Ménière;s disease: age, duration of vertigo, tinnitus, hearing loss and aural fullness, and unilateral or bilateral involvement.

[The Meninos do Rio Program: lifeworld, adolescence, and health risks].

This study focuses on health risks among teenagers from two towns in the Sao Francisco River Valley (Ibiai and Morada Nova) and slums in Morro das Pedras, Belo Horizonte, Minas Gerais State, Brazil. The study discusses teaching and extracurricular activities by the Federal University in Minas Gerais in these localities, aimed at promoting health in adolescence. The authors use the Habermas communicative action theory as the main theoretical and methodological approach.
