Prótesis radífera: Alternativa en el tratamiento de neoplasias de cabeza y cuello

Radipherpus protheses are a means of treatment for malignant tumor-carrying patients. These protheses are used in cases of brachytherapy or external actinotherapy by contact and allow treating them with high radiation doses that are quickly released from the areas next to tumor, so that the radiations be restricted to the affected region, without the emissions damaging or destroying the soft tissues. Based on these considerations, the present paper was aimed at making literature review on the use of radipherous protheses for the treatment of head and neck neoplasias. © 2006 1995, Editorial Ciencias médicas.

Sobredentadura inmediata y con carga tardía: Revisión de la literatura

The oral rehabilitation of the patients toothless totals presents large difficulties, because diverse factors act limiting the treatment with complete dentures conventional, as severe reabsorption of the alveolar process, generating for the phonetic patient difficulties and of mastication, annoyance, retention lack and stability of the prosthesis. With the emergence of you implant them osseointegratin idealized by Prof o Branemark, these aspects were improved by means of the possibility of new treatment options, as the overdentures tissue-implant-supported. However, the protocol of Branemark demanded a period of scaring from three to six months, owing the patients to await this time for the placement of the final prosthesis. This way, the surgical technique of immediate load was proposed to abbreviate this period, improving the transition phase, at the same time that it reduces the problems psychological associates. This way, the objective of the present study is to carry out a literature revision about the works that used overdentures comparing immediate and late load, the best alternative and factors wrapped in the success of the procedure discussing. © 2008 1995, Editorial Ciencias médicas.

Instalación inmediata de prótesis provisionales en la reapertura de implantes

The study of techniques to reach aesthetics in the anterior region when using osseointegrated implants is of great importance. A literature review was made to compare effivciency and suitability of immediate provisionalization in re-opening of osseointegrated implants with respect to the set time (use of standardized cicatrizants and emergency profile cicatrizants). Immediate provisional denture in the phase of re-opening makes the restoration of the gingival contourn quicker when compared to the use of cicatrizants without intermediate phases required. © 2008 1995, Editorial Ciencias médicas.

Espermidina e espermina exogena na micropropagação de Aloe vera (L.) Burm

The lateral shoots of the Aloe vera L. Burm have been inoculated in culture medium. The work has been divided in two phases. In the phase I different concentrations of NAA and BAP were added to the MS . In the phase II, plants proceeding of the MS were inoculated in medium containing or not spermidine and/or spermine. In the phase I the best results for mass production and shooting came out with the use of MS + 8,88 m mol L -1 BAP + 5,36 m mol L -1 NAA and these treatments didn't induce the rooting. Plants submitted to treatments with polyamines presented emission of roots during the phase II, suggesting possible inductor effect when used by isolated means during the rooting. No traces of oxidation were noted in the culture medium containing the polyamines. The use of spermidine in the culture-medium promoted a greater mass increasing and the most number of shoots was obtained with the use of the combination of polyamines. © 2008 1999, Editorial Ciencias Médicas.

Representación social del paciente que se beneficia de la interacción universidad pública y hospitales generales

Hospitals are very important for the health system. The objective of this quali-quantitative research was to visualize patients' social representation, which profited of the interaction between public universities and hospitals. 105 patients in the waiting rooms at the Integrated Clinic at FOA _ UNESP in the first semester 2005 answered to the question: How did you know about the service at FOA? - in opened interviews, recorded or written. A collective speech of the subject represented the field that allouds a society to speak as one. Twenty three of all patients have been sent to FOA by Health Assistance Centers in Araçatuba (7) and region (16) and twenty one patients assisted in Araçatuba by emergency. We can observe that the interaction between the public universities and general hospitals is a reality.

Micropropagación de Pothomorphe umbellata (L.) Miq. vía organogénesis directa

The present research was aimed at standardizing the protocol of seed disinfection, seed germination and organogenesis via callus of Pothomorphe umbellata (L.) Miq.The germinated seeds were inoculated in different concentrations of BAP (benzylamine purine) and NAA (naphthalene acetic acid) in order to stimulate the callus induction. After 60 days of culture, the calluses with some shoots were taken to an organogenesis medium (GA3 0.1 mg.L -1, BAP 0.5 mg.L-1) during 40 days, to be transferred later to a development medium. Finally, the plantules were acclimatized, presenting a good index of survival.

Técnicas de confección de prótesis facials

Facial prostheses are a integral part of rehabilitation of patients underwent face damages, being of pathologic, traumatic or congenital origin. Although success of treatment with facial prostheses is associated with artistic ability of professional to reproduce lost structures, we can not to obviate the good adaptability of prostheses regards association of material and techniques used to make buccomaxillofacial prostheses.

La influencia de factores sistémicos en el uso de las prótesis totales

According to the possible influence of systemic diseases and of drugs used for its treatment in buccal cavity, the aim of present study is to carry out a review of literature on this topic, emphasizing on influence of these factors on use of the total prostheses (PTs), allowing to surgeon-dentist a better scientific knowledge to creation of this type of rehabilitation treatment.

Hallazgos clínico-radiológicos de la articulación temporomandibular en pacientes con artritis reumatoide

Aim of present paper is to describe and to assess the Clinicoradiological findings of the temporomandibular joint (TMJ) in a group of patients diagnosed with rheumatoid arthritis (RA). Sample included 61 patients with a mean age of 54 years and 5 months. All of them were interrogated and clinically examined and then underwent to a radiographic examination of both TMJs, using the transcranial projection technique, with the closed mouth and in maximal opening. Study includes the TMJ syndrome founded such as pain, tumefaction, luxation, clicking, and a limited oral opening. The study of radiographic features showed the presence of changes in condyle surface and temporal fossa, in condylar motility, and articulation space. We conclude that in patients presenting with rheumatoid arthritis is frequent the presence of clinicoradiological findings in the TMJ, and that patient's age and gender and the activity level and the RA course time, are factors influencing in TMJs general status.

Evaluación de la deformación de dos siliconas para prótesis faciales, influencia de la pigmentación y desinfección química

The purpose of present study was to analyze the effect of pigmentation and chemical disinfection on the initial and the permanent deformation of two silicones (Silved Selant and Brascoved) for facial prosthesis. Initial and permanent deformation tests samples (20 mm × 12.5 mm) were made following the manufacturer's instructions. For each silicone (n= 40), ten samples were used for pigmentation with make up power, ten with iron oxide, ten with ceramics power and tem were tested without pigmentation. Five samples of each group were submitted to chemical disinfection using a 2 % Chlorhexidine spray. All samples were immersed in physiological saline and stored in an oven at 35 ° ± 1 °C. After 90 days, the samples were submitted to initial and permanent deformation tests using a dial indicator. For both properties, data were analyzed by Tukey's test (a= 0.05). The results showed that all the materials had initial and permanent deformation regardless of pigmentation and chemical disinfection. The groups were used for pigmentation with iron oxide showed less initial and permanent deformation when were submitted to the chemical disinfection regardless the silicone used.

Estética en prótesis removibles

Nowadays, aesthetics is very appreciated in the social context and a attractive smile is the object of desire in most of patients requiring prosthesis treatment. In case of removable prosthesis, total or partial, this feature is more significant since some or all teeth may be absents. Implants leading to a significant improvement in relation to function and comfort of removable prosthesis users, but the aesthetics of these prostheses had little attention in the current scientific literature. Thus, the aim of present article was to make a review of the literature on the aesthetic features related to rehabilitation with removable prostheses. In present study we found as significant factors for the aesthetics in removable partial and total prostheses: Selection of artificial teeth and their arrangement, characterization of acrylic resin basis and also the types and location of retainers for the removable partial prostheses. We conclude that the involvement and the aesthetic knowledge during the appropriate planning of this process is responsibility of the professional.

Utilização de extratos de plantas medicinais e óleo de Eucaliptus no controle in vitro de Microsporum canis

INTRODUCTION: Microsporum canis is the most common cause of canine and feline dermatophytosis and thus has an important zoonotic role. OBJECTIVES: the aim of this study was to determine the antifungal action of medicinal plant extracts and of eucalyptus oil against pathogenic fungus Microsporum canis. METHODS: the extracts were prepared by mixing 300 g of previously washed leaves with 450 mL of distilled water. Then the material was triturated, filtered, sterilized and conserved at 10 + 2 oC. Fifteen milliliters of sterilized medium Sabouraud dextrose (Difco) at a temperature of 55 + 1 oC was added in Petri dishes containing the extracts in one, two, three, four and five mm concentrations. The fungus was inoculated once the medium was solidified. The inoculated dishes were maintained in B.O.D. incubator at 36 ± 0,5 oC until the fungus developed in the controls. RESULTS: the extracts from Punica granatum, Mangifera indica and Eucalyptus spp reduced the growth of fungus, but the extracts from Cymgopogom nardus, Tagetes minuta, Ruta graviolens, Cyperus rotundus, Annona moricata and Calendula spp leaves and flowers boosted the growth of fungus. The other extracts and the eucalyptus oil neither show any fungicidal action nor encourage mycelium growth. CONCLUSIONS: the use of most tested extracts and eucalyptus oil is not suitable for the treatment of Microsporum canis dermatophytosis due to lack of inhibitory effects. The extracts from Cymgopogom nardus, Tagetes minuta, Ruta graviolens, Cyperus rotundus, Annona moricata and from of Calendula spp leaves and flowers help the development of the fungus making clear that phytotherapy should be properly used, otherwise it can worsen the problem. However; extracts from Mangifera indica, Punica granatum and Eucalyptus spp. can be used as fungistatic.
