Efeitos do manejo comportamental de incontinência fecal em adolescente

A incontinência fecal, também conhecida como encoprese, é um transtorno de evacuação que acarreta prejuízos ao desenvolvimento psicossocial e orgânico da criança e do adolescente, e que demanda atenção e cuidado de pais e profissionais de saúde. No amplo contexto de tratamento da encoprese, a psicoterapia constitui importante recurso, sendo a terapia comportamental apontada como uma das modalidades mais promissoras e eficazes para o tratamento dessa dificuldade de eliminação. Este artigo apresenta o estudo dos efeitos do manejo comportamental de quadro de incontinência fecal em um adolescente de 14 anos, atendido em clínica-escola de Psicologia do interior do Estado de São Paulo durante 14 meses. A partir do referencial teórico da análise do comportamento, foi desenvolvido, em contexto psicoterápico, um conjunto de estratégias comportamentais com o cliente, bem como orientações aos pais, visando à gradativa extinção encoprética. No decorrer desse processo, o cliente apresentou significativas aquisições comportamentais de uso regular do banheiro e adequado controle esfincteriano, monitoradas semanalmente, que possibilitaram a plena extinção das ocorrências de sujidade, sendo avaliado o efeito em follow-up realizado três meses após o encerramento dessa intervenção.

Psicoterapia grupal no transtorno obsessivo-compulsivo

There are few published papers about group psychotherapy for patients with obsessive-compulsive disorder (OCD), and usually restricted psychoeducational, support or cognitive-behavioral approaches. This article describes the experience of group psychotherapy for OCD patients started in 1996 in Botucatu Medical School - Unesp, São Paulo, Brazil. The two-hour sessions occur once a month, with 6 to 10 female patients, and are based on psychodramatic techniques. Psychotropic prescriptions are given after the sessions. In the beginning, aggressive obsessions were more prominent and were reported with much anguish and shame. Gradually, the themes changed from OCD specific issues (symptoms, pharmacological treatment, outcome, need of exposure and response prevention) to deeper and more personal psychodynamic aspects. The psychodramatic approach (techniques of double, mirror, role inversion, search for prymary scenes) has mostly shown: difficulty in accepting their own human mistakes or negative emotions due to excessive personal demands. This seems to generate guilt, low self-esteem, idealization of others, difficulty in enjoying pleasant situations, fear of taking responsibilities and of losing control (madness/aggressiveness). The group has been considered very important by the patients, since sharing experiences helps to diminish feelings of isolation, shame and guilt, stimulates the exposure to feared situations and enhances self-esteem. The fact that all participants have the same disorder favors group cohesion and provides relief, as they see in the others some of their afflictions and are able to share similar feelings and experiences. Many times the burden of the symptoms are dealt with humor. The confidence in such therapeutic setting is helping the identification and resolution of personal conflicts and contributing to the adherence to pharmacological treatment. The group also provides valuable training experiences for resident physicians in psychiatry.

Role-playing como estratégia facilitadora da análise funcional em contexto clínico

In behavioral therapy several techniques are used, among them the role-playing and functional analysis. Role-playing is feasible to model relevant behaviors while functional analysis is used for diagnostic evaluation and to produce self-knowledge. However, some clinical problems have characteristics that hinder the creation of self-knowledge, without which the client may not develop the modeling of alternative repertoires. This study aims to illustrate the combination of role-playing and functional analysis as a procedure to facilitate the development of self-awareness in clients with deficits in discrimination of functional relations and interpersonal difficulties. A session was selected from a total of 12 group meetings. The main result was the increase of self-revelations and discrimination of functional relationships by customers. It is concluded that the role-playing can be an environment to teach the client to describe functional relations and produce self-knowledge when facing interpersonal problems and difficulties on the discrimination of the actual contingencies in place.

Cellular and extracellular behavior in the gerbil (Meriones unguiculatus) ventral prostate following different types of castration and the consequences of testosterone replacement

Mongolian gerbils (Meriones unguiculatus) were grouped into two experimental groups: GEx.01 suffered orchiectomy and after 30 days received doses of testosterone cipionate (T), while GEx.02 received weekly and alternated doses of the anti-androgens cyproterone acetate and flutamide for 30 days, and the animals were then euthanized. Structural evaluation reveals a more intense reduction in epithelial height in GEx.02. Smooth muscle cells (SMC) presented a star-shaped aspect after 30 days of hormonal ablation and basal membrane was shown to be more intensely grooved in GEx.01. In both groups, after hormonal replacement, recovery in epithelial height could be noted and the SMC presented its phenotypes, but an increase in RER was seen, characterizing a modulation from its contractile to secreting phenotype. In conclusion, the prostate presented involution capacity after androgen ablation and the ability to reorganize after hormonal replacement, but events resulting from orchiectomy and subsequent T replacement were shown to be more aggressive to the prostate.

The use of fragments of thin veneers as a restorative therapy for anterior teeth disharmony: A case report with 3 years of follow-up

Aim: The present case report described the use of contact lens of thin porcelain veneers as a restorative therapy to solve anterior teeth disharmony. Background: Fragments of thin veneers are minimally invasive restorations with little or no dental preparation and present thickness ranging from 0.2 to 0.5 mm. They are used in case of diastema closure, small changes of teeth, color and restoration of teeth with small fractures. Case report: A 25-year-old man was admitted at a dental clinic complaining about the diastema presence on the upper anterior teeth. Patient was referred to an orthodontic treatment in order to provide better distribution of the diastemas and harmonious proportion of the teeth. Afterwards, contact lens of thin porcelain veneers were fabricated on the six upper anterior teeth. Conclusion: Based on the outcomes of this clinical report, we considered the use of fragments of thin veneers as a successful treatment option after 3 years of follow-up. Clinical significance: The fragments of thin veneers have been established to be an interesting alternative to esthetically restore the anterior teeth with minimal invasiveness. However, since it is a new treatment modality, longitudinal studies are necessary to understand the material's behavior.

Nasal administration of liquid crystal precursor mucoadhesive vehicle as an alternative antiretroviral therapy

The purpose of this study was to develop a mucoadhesive stimuli-sensitive drug delivery system for nasal administration of zidovudine (AZT). The system was prepared by formulating a low viscosity precursor of a liquid crystal phase, taking advantage of its lyotropic phase behavior. Flow rheology measurements showed that the formulation composed of PPG-5-CETETH-20, oleic acid and water (55, 30, 15% w/w), denominated P, has Newtonian flow behavior. Polarized light microscopy (PLM) revealed that formulation P is isotropic, whereas its 1:1 (w/w) dilution with artificial nasal mucus (ANM) changed the system to an anisotropic lamellar phase (PD). Oscillatory frequency sweep analysis showed that PD has a high storage modulus (G′) at nasal temperatures. Measurement of the mucoadhesive force against excised porcine nasal mucosa or a mucin disk proved that the transition to the lamellar phase tripled the work of mucoadhesion. Ex vivo permeation studies across porcine nasal mucosa exhibited an 18-fold rise in the permeability of AZT from the formulation. The Weibull mathematical model suggested that the AZT is released by Fickian diffusion mechanisms. Hence, the physicochemical characterization, combined with ex vivo studies, revealed that the PPG-5-CETETH-20, oleic acid, and water formulation could form a mucoadhesive matrix in contact with nasal mucus that promoted nasal absorption of the AZT. For an in vivo assessment, the plasma concentrations of AZT in rats were determined by HPLC method following intravenous and intranasal administration of AZT-loaded P formulation (PA) and AZT solution, respectively, at a dose of 8 mg/kg. The intranasal administration of PA resulted in a fast absorption process (Tmax = 6.7 min). Therefore, a liquid crystal precursor formulation administered by the nasal route might represent a promising novel tool for the systemic delivery of AZT and other antiretroviral drugs. In the present study, the uptake of AZT absorption in the nasal mucosa was demonstrated, providing new foundations for clinical trials in patients with AIDS. © 2012 Elsevier B.V.

Phenotypic and metabolic aspects of prostatic epithelial cells in aged gerbils after antisteroidal therapy: Turnover in the state of chromatin condensation and androgen-independent cell replacement

The gerbil is a rodent considered a good model for studies of prostatic morphophysiology under different experimental conditions. Studies involving castration and steroidal blockers of aged gerbils showed that the glandular epithelium persists after long-term therapy, preventing the organ atrophy. Thus, the objective of this study was to evaluate the phenotypic characteristics and behavior of prostatic epithelial cells that remained after different periods of hormone ablation in aged gerbils. The identification of elements that influenced the survival of this cell type was performed by morphometric, nuclear phenotypes, ultrastructural and immune histochemical analysis. The most significant responses to treatment, by analyzing morphometric features, were observed during the first three time points (day 1, day 3, and day 7), after which there appeared to be an adjustment of the gland to the hormone ablation. All treatments led to changes in the state of chromatin condensation, DNA methylation pattern and phenotypic changes indicated cell senescence. Additionally, an increase in the basal cells seemed to guarantee self-renewal properties to the epithelium. These data indicate that changes occur at many levels, including gene expression and nuclear architecture in the epithelial cells, when aging and steroidal blockade are associated. These aspects are important when considering castration-resistant prostate cancer, a malignant tumor posing difficult therapeutic intervention. © 2013 Elsevier GmbH. All rights reserved.

Influence of clinical therapy and nutritional counseling on the recurrence of urolithiasis

PURPOSE: To evaluate the influence of combined clinical therapy and nutritional guidance on the recurrence of urolithiasis. METHODS: From our registry of patients with recurrent urolithiasis we selected 57 who had at least 5-years of follow-up. We collected 24h urine samples in order to analyze Ca, Na, uric acid, citrate, oxalate, and Mg concentrations and to assess urine volume. Patients filled out a clinical questionnaire before treatment, and abdominal radiographs and/or ultrasound were performed both before treatment and during the follow-up period. During follow-up, specific and individualized dietary advice was given based on the individual's metabolic disorders. Patients also received specific pharmacological treatment for their metabolic alterations. Outcome measures were metabolites in urine and the urolith recurrence rate. Pre- and post- intervention values were compared using tests as appropriate. RESULTS: Fifty six of the patients were male and the majority of patients were overweight. The mean BMI was 27 kg/m2. Urinary excretion of calcium, uric acid and sodium decreased significantly over the five year follow-up period. The number of uroliths that formed during the 5-year follow-up also decreased significantly compared to pre-treatment values. CONCLUSION: Individualized dietary advice combined with pharmacological treatment significantly reduces long-term urolithiasis recurrence.

Trajectory and outcomes of speech language therapy in the Prader-Willi syndrome (PWS): case report

The aim of this study was to describe the trajectory and the outcomes of speech-language therapy in Prader-Willi syndrome through a longitudinal study of the case of an 8 year-old boy, along four years of speech-language therapy follow-up. The therapy sessions were filmed and documental analysis of information from the child's records regarding anamnesis, evaluation and speech-language therapy reports and multidisciplinary evaluations were carried out. The child presented typical characteristics of Prader-Willi syndrome, such as obesity, hyperfagia, anxiety, behavioral problems and self aggression episodes. Speech-language pathology evaluation showed orofacial hypotony, sialorrhea, hypernasal voice, cognitive deficits, oral comprehension difficulties, communication using gestures and unintelligible isolated words. Initially, speech-language therapy had the aim to promote the language development emphasizing social interaction through recreational activities. With the evolution of the case, the main focus became the development of conversation and narrative abilities. It were observed improvements in attention, symbolic play, social contact and behavior. Moreover, there was an increase in vocabulary, and evolution in oral comprehension and the development of narrative abilities. Hence, speech-language pathology intervention in the case described was effective in different linguistic levels, regarding phonological, syntactic, lexical and pragmatic abilities.
