Quality of life in elderly with dizziness

Dizziness is frequent in elderly people. Aims: To evaluate the Quality of Life (QoL) in elderly subjects with dizziness, relate it with gender and age. Material and Method: A prospective study comprising 120 elderly patients with dizziness evaluated with Brazilian versions of the Whoqol-bref and the dizziness handicap inventory (DHI). The factor analysis (FA), the Mann Whitney and Kruskal Wallis tests, and the Spearman correlation were applied to study the results. Results: The most compromised domains were the DHI physical domain and the Whoqol-bref physical and environment domains. FA resulted in 3 factors in the DHI and 5 factors in the Whoqol-bref. There was a moderate correlation (-0.596) in the total scores of both instruments. Males had a better QoL in the ""environment perception and introspectivity"" and ""health perception"" factors of the Whoqol-bref test. Females had a better QoL in the ""functionality perception"" factor of the Whoqol-bref test. There were no significant age differences. Conclusions: Elderly patients with dizziness have a worse QoL. Elderly females with dizziness have worse QoL scores in ""environment perception and introspectivity"" and ""health perception"" and better QoL in the ""functionality perception"" factor compared to elderly males.

Conduct after Epley`s maneuver in elderly with posterior canal BPPV in the posterior canal

Benign Paroxysmal Positional Vertigo is the most common peripheral vestibular disorder, especially in the elderly and presents as the predominant etiology in this population of the degeneration of the utricular macula. Aim: To compare the effectiveness of the approaches after Epley maneuver. Study Design: longitudinal cohort. Materials and Methods: The study included 53 volunteers with Benign Paroxysmal Positional Vertigo of the posterior semicircular canal, divided into Group 1, who underwent Epley maneuver associated with the use of neck collar and post-maneuver instructions, Group 2 underwent the Epley maneuver without the use cervical collar and/or post-maneuver restrictions, and Group 3 underwent the Epley maneuver associated with the use of a mini vibrator, without the use of neck collar and/or post-maneuver restrictions. Results: In the three groups, the number of Epley maneuvers ranged from one to three. We employed the Brazilian Dizziness Handicap Inventory - pre- and post-treatment and observed a statistically significant difference on most scores pre- and post-treatment for both groups. Conclusion: Regardless of the post Epley maneuver treatment selected for the treatment of Benign Paroxysmal Positional Vertigo, it was effective when comparing the Brazilian Dizziness Handicap Inventory pre- and post-treatment.

Repetitive transcranial magnetic stimulation improve tinnitus in normal hearing patients: a double-blind controlled, clinical and neuroimaging outcome study

Background and purpose: Tinnitus is a frequent disorder which is very difficult to treat and there is compelling evidence that tinnitus is associated with functional alterations in the central nervous system. Targeted modulation of tinnitus-related cortical activity has been proposed as a promising new treatment approach. We aimed to investigate both immediate and long-term effects of low frequency (1 Hz) repetitive transcranial magnetic stimulation (rTMS) in patients with tinnitus and normal hearing. Methods: Using a parallel design, 20 patients were randomized to receive either active or placebo stimulation over the left temporoparietal cortex for five consecutive days. Treatment results were assessed by using the Tinnitus Handicap Inventory. Ethyl cysteinate dimmer-single photon emission computed tomography (SPECT) imaging was performed before and 14 days after rTMS. Results: After active rTMS there was significant improvement of the tinnitus score as compared to sham rTMS for up to 6 months after stimulation. SPECT measurements demonstrated a reduction of metabolic activity in the inferior left temporal lobe after active rTMS. Conclusion: These results support the potential of rTMS as a new therapeutic tool for the treatment of chronic tinnitus, by demonstrating a significant reduction of tinnitus complaints over a period of at least 6 months and significant reduction of neural activity in the inferior temporal cortex, despite the stimulation applied on the superior temporal cortex.

The impact of gender, age and hearing loss on tinnitus severity

Tinnitus is a symptom present in approximately 15% of the world population. Most patients are between 40 and 80 years of age; the prevalence above 60 reaches 33%. About 20% have moderate to severe impact in the quality of life but the factors associated with the tinnitus annoyance are not completely known. Aim: The objective of this study is to evaluate the relationship between age, gender and hearing loss on tinnitus annoyance. Materials and methods: 68 patients were evaluated at the tinnitus center at our hospital, from March 2007 to march 2008, with a detailed interview, complete otolaryngological examination, the Portuguese version of the Tinnitus Handicap Inventory and pure tone audiometry. Results: Age varied from 24 to 83 (mean=59); the mean THI value was 39 (females: 36; males: 44). THI grades were: slight: 32.3%; mild: 19.1%; moderate: 20.6%; severe: 13.2% and catastrophic: 14.7%. No significant correlation was found between gender (p=0.30), age (p=0.77) hearing loss (p>0.05 for all averages analyzed) and tinnitus severity. Conclusion: Gender, age and hearing loss do not influence tinnitus annoyance, using the THI.

Adaptação transcultural e consistência interna do Early Trauma Inventory (ETI)

As experiências traumáticas precoces são um fator de risco preditivo de problemas psicopatológicos futuros. O Early Trauma Inventory (ETI) é um instrumento que avalia em indivíduos adultos experiências traumáticas ocorridas antes dos 18 anos de idade. Tal instrumento foi traduzido, transculturalmente adaptado e sua consistência interna foi avaliada. Vítimas de violência que preencheram os critérios de inclusão e exclusão foram submetidas a uma entrevista diagnóstica (SCID-I) e ao ETI. Foram incluídos 91 pacientes com o transtorno do estresse pós-traumático (TEPT). O alfa de Cronbach nos diferentes domínios variou de 0,595-0,793, e o escore total foi de 0,878. A maior parte dos itens nos vários domínios, com exceção do abuso emocional, apresentou índices de correlação interitem entre 0,51-0,99. A versão adaptada foi útil tanto na clínica quanto na pesquisa. Apresentou boa consistência interna e na correlação interitem. O ETI é um instrumento válido, com boa consistência para se avaliar a presença de história de traumas precoces em indivíduos adultos.

Assessment of Personality Dimensions in Children and Adolescents with Bipolar Disorder Using the Junior Temperament and Character Inventory

Objective: We compared temperament and character traits in children and adolescents with bipolar disorder (BP) and healthy control (HC) subjects. Method: Sixty nine subjects (38 BP and 31 HC), 8-17 years old, were assessed with the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime. Temperament and character traits were measured with parent and child versions of the Junior Temperament and Character Inventory. Results: BP subjects scored higher on novelty seeking, harm avoidance, and fantasy subscales, and lower on reward dependence, persistence, self-directedness, and cooperativeness compared to HC(all p < 0.007), by child and parent reports. These findings were consistent in both children and adolescents. Higher parent-rated novelty seeking, lower self-directedness, and lower cooperativeness were associated with co-morbid attention-deficit/hyperactivity disorder (ADHD). Lower parent-rated reward dependence was associated with co-morbid conduct disorder, and higher child-rated persistence was associated with co-morbid anxiety. Conclusions: These findings support previous reports of differences in temperament in BP children and adolescents and may assist in a greater understating of BP children and adolescents beyond mood symptomatology.

Validation of brief pain inventory to Brazilian patients with pain

To validate the Brazilian version of the Brief Pain Inventory (BPI-B) scale and to determine the optimal cutpoints for mild, moderate, and severe pain based on patients` rating of their worst pain. One hundred forty-three outpatients with cancer were recruited in Hospital das Clinicas-University of Sao Paulo, Brazil. Confirmatory factor analysis confirmed two underlying dimensions, pain severity, and pain interference, with Cronbach`s alpha of 0.91 and 0.87, respectively. Convergent validity was shown by the correlation observed between the BPI dimensions with the EORTC-QLQ-C30 pain scale and the McGill Pain Questionnaire. The BPI-B detected significant differences in the two dimensions by disease and performance status, supporting known-group validity. For the worst pain, the optimal cutpoints were 4 and 7 (1-4 = mild pain, 5-7 = moderate, and 8-10 = severe). Our data show that BPI-B is a brief, useful, and valid tool for assessing pain and its impact on patient`s life.

Further psychometric study of the Beck Anxiety Inventory including factorial analysis and social anxiety disorder screening

Objective. To analyze the psychometric properties of the Brazilian Portuguese version of the Beck Anxiety Inventory (BAI) in terms of its internal consistency, scores distribution, concurrent and discriminant validity, and factorial analysis in a sample of university students and social anxiety disorder (SAD) cases and non-cases. Methods. A sample of Brazilian university students from the general population (N = 2314) and a sample of university students identified as cases (N = 88) and non-cases (N = 90) of SAD were assessed, using as a parameter the Structured Clinical Interview for the DSM-IV. The different instruments were completed individually in the presence of an experienced rater. Results. The BAI showed adequate internal consistency (0.88-0.92) and discriminant validity, with 0.74 sensitivity and 0.71 specificity for a cut-off score of 10. The factorial analysis suggested a three-factor solution to be the most adequate. Conclusions. The version of the BAI studied is quite adequate to be used in the context of Brazilian university students, identifying the presence of anxiety indicators. However, its usefulness to screen for SAD seems limited.

Evaluation of the psychometric properties of the Social Phobia Inventory in university students

Objective: The aim of the study was to study the psychometric properties of the Social Phobia Inventory (SPIN) in its version for the context of Brazilian adults. Methods: A sample of Brazilian university students from the general population (n = 2314) and a sample of university students identified as cases (n = 88) and noncases (n = 90) of social phobia were assessed, using as a parameter the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The different instruments were applied individually in the presence of a rater. Results: The SPIN showed adequate internal consistency (.63-.90) and concurrent validity with different instruments of auto- and hetero-evaluation of social phobia. Discriminative validity showed 0.84 to 0.86 sensitivity and 0.84 to 0.87 specificity for cutoff notes between 19 and 21. Factorial analysis showed the presence of a variable number of factors as a function of the different samples. Conclusions: The version of the SPIN studied is quite adequate for use in the context of Brazilian university students, favoring the screening of social phobia. However, further studies using more diverse samples are needed. (C) 2010 Elsevier Inc. All rights reserved.

Floristic inventory of cerrado at Pedregulho, Sao Paulo State, Brazil

Pedregulho municipality in the far northeastern region of Sao Paulo state has fragments of cerrado vegetation thought to be floristically distinct from other cerrado remmants in the state. In this study, a floristic survey was carried out at Pedregulho, focusing on two geologically distinct regions: Furnas do Bom Jesus State Park and the Estreito district. In each region, 50x50 m plots were set up for a total sample area of 1 hectare, where 65 families and 379 angiosperm species were recorded. Collecting efforts in adjacent areas resulted in a total of 71 families and 443 species. The two study areas had low floristic similarity. Geographic species distribution was analyzed and eight patterns were defined for those species restricted to the Pedregulho region in Sao Paulo.

Communicative and psycholinguistic abilities in children with phenylketonuria and congenital hypothyroidism

The Neonatal Screening for Inborn Errors of Metabolism of the Association of Parents and Friends of Special Needs Individuals (APAE) - Bauru, Brazil, was implanted and accredited by the Brazilian Ministry of Health in 1998. It covers about 286 cities of the Bauru region and 420 collection spots. Their activities include screening, diagnosis, treatment and assistance to congenital hypothyroidism (CH) and phenylketonuria (PKU), among others. In 2005, a partnership was established with the Department of Speech-Language Pathology and Audiology, Bauru School of Dentistry, University of São Paulo, Bauru, seeking to characterize and to follow, by means of research studies, the development of the communicative abilities of children with CH and PKU. OBJECTIVE: The aim of this study was to describe communicative and psycholinguistic abilities in children with CH and PKU. MATERIALS AND METHODS: Sixty-eight children (25 children aged 1 to 120 months with PKU and 43 children aged 1 to 60 months with CH) participated in the study. The handbooks were analyzed and different instruments were applied (Observation of Communication Behavior, Early Language Milestone Scale, Peabody Picture Vocabulary Test, Gesell & Amatruda's Behavioral Development Scale, Portage Operation Inventory, Language Development Evaluation Scale, Denver Developmental Screening Test, ABFW Child Language Test-phonology and Illinois Test of Psycholinguistic Abilities), according to the children's age group and developmental level. RESULTS: It was observed that the children with PKU and CH at risk for alterations in their developmental abilities (motor, cognitive, linguistic, adaptive and personal-social), mainly in the first years of life. Alterations in the psycholinguistic abilities were also found, mainly after the preschool age. Attention deficits, language and cognitive alterations were more often observed in children with CH, while attention deficits with hyperactivity and alterations in the personal-social, language and motor adaptive abilities were more frequent in children with PKU. CONCLUSION: CH and PKU can cause communicative and psycholinguistic alterations that compromise the communication and affect the social integration and learning of these individuals, proving the need of having these abilities assisted by a speech and language pathologist.

Nesse estudo, foi realizado um levantamento florístico em Pedregulho, abordando duas regiões geologicamente distintas: o Parque Estadual das Furnas do Bom Jesus e o distrito de Estreito. Em cada uma, delimitaram-se duas parcelas de 50×50 m, totalizando um hectare, onde foram encontradas 65 famílias e 379 espécies de angiospermas. Coletas em áreas adjacentes totalizaram 71 famílias e 443 espécies. As duas regiões estudadas têm baixa similaridade florística entre si. A distribuição geográfica das espécies é analisada e oito padrões são delimitados para aquelas cuja distribuição no Estado de São Paulo é restrita à região de Pedregulho.

Two new species of the Hypostomus cochliodon group (Siluriformes: Loricariidae) from the rio Negro basin in Brazil

Two new species of Hypostomus are described from the middle and upper rio Negro in Brazil. They are assigned to the Hypostomus cochliodon group (sensu Armbruster, 2003) by possessing few spoon-shaped teeth, and dentary angle averaging less than 80º. Hypostomus kopeyaka is described from the rio Tiquié, a tributary of the rio Uaupés, upper rio Negro basin, presents a unique color pattern among the Hypostomus species belonging to the Hypostomus cochliodon group, consisting of conspicuously horizontally elongated, closely-set black spots over the entire dorsal and lateral surfaces of the body. Hypostomus weberi is described from the middle rio Negro and can be distinguished from all remaining Hypostomus species belonging to the Hypostomus cochliodon group by possessing a unique color pattern consisting in large, rounded, widelyspaced black spots over body and fins.

Morcegos (Mammalia: Chiroptera) da Estação Ecológica Serra Geral do Tocantins: composição específica e considerações taxonômicas

Registramos 39 espécies de quirópteros na Estação Ecológica Serra Geral do Tocantins e áreas adjacentes, nordeste do estado do Tocantins, durante 28 dias de trabalho de campo nos anos de 2003 e 2008 e na estação chuvosa. Este estudo da quiropterofauna é um dos primeiros para o estado do Tocantins, aumentando o número de espécies conhecido para esta região, com 29 espécies registradas pela primeira vez no estado. As espécies mais abundantes foram P. lineatus e C. perspicillata, com 23,5 e 15,4% do total de capturas. A diversidade no nível de família também foi alta: Phyllostomidae (26 espécies), Vespertilionidae (5), Molossidae (3), Emballonuridae (2), Mormoopidae (1), Noctilionidae (1) e Thyropteridae (1). A maioria das áreas mésicas e de cerrado (s.s.) não estão incluídas em unidades de conservação, representando uma ameaça para espécies restritas a estes tipos de hábitats, como T. devivoi que foi capturada apenas em áreas de veredas com Heliconiacea. Além disso, a região vem sendo alterada devido ao rápido avanço da agricultura e pastagens e do turismo crescente. Assim, a elevada diversidade de morcegos registrada na região, além dos diversos papéis ecológicos que estas espécies desempenham, somadas às ameaças acima relatadas, aumentam as prioridades em se estabelecer estratégias de conservação para este grupo de mamíferos nas regiões adjacentes à Estação Ecológica Serra Geral do Tocantins. Dentre as espécies com interesse taxonômico, biogeográfico e de conservação destacam-se Lonchophylla dekeyseri, Glyphonycteris behnii, Micronycteris sanborni, Artibeus anderseni, Sturnira tildae e a recém-descrita Thyroptera devivoi.

Anfíbios da Estação Ecológica Serra Geral do Tocantins, região do Jalapão, Estados do Tocantins e Bahia

A porção norte do domínio do Cerrado é uma das áreas historicamente menos conhecidas com relação à sua biodiversidade. Recentemente, alguns estudos tem revelado valores de riqueza comparáveis a outras regiões dentro do domínio. A Estação Ecológica Serra Geral do Tocantins (EESGT) está localizada na região do Jalapão, porção Nordeste do Cerrado, e faz parte do maior bloco de áreas protegidas neste domínio. Neste estudo descrevemos a riqueza e composição de espécies de anfíbios da EESGT, discutindo-as em um contexto biogeográfico, e caracterizamos o uso de sítios reprodutivos pelas espécies de anfíbios registradas em relação às fitofisionomias e aos tipos de corpos d'água. Utilizamos os métodos de busca ativa e armadilhas de queda, no período considerado como o auge da estação reprodutiva para a maior parte das espécies do Cerrado. Foram registradas 36 espécies de anfíbios na EESGT, totalizando 39 espécies conhecidas para a região do Jalapão. Aplicando o estimador Jackknife, sugerimos uma riqueza potencial de 42 espécies para a EESGT. A maior parte das espécies registradas é endêmica ou fortemente associada ao Cerrado, seguidas pelas espécies de ampla distribuição no Brasil ou América do Sul. A maior parte da espécies se reproduz em poças temporárias localizadas em áreas abertas, embora existam espécies que ocorrem exclusivamente em matas de galeria e utilizem corpos d'água lóticos para se reproduzir.
