Falls in older adults: a practical approach.

BACKGROUND: Falls are a major problem in public health since they are an important cause of morbidity and mortality. To evaluate the risk of fall and prescribe preventive interventions may be a challenging task. OBJECTIVES: The objectives of this study are to summarize the most relevant information on the topic "falls in the elderly" and to give a critical view and practical clinical approach on this topic. METHODS: In March 2022, a search of Pubmed database was performed, using the terms "fall elderly", fall prevention", "fall risk", with the following parameters: five years, review, systematic review, meta-analysis, practice guidelines. RESULTS: There are several risk factors for falls that can be grouped in different areas (psychosocial, demographic, medical, medication, behavioral, environmental). The clinical evaluation of an older adult prone to falls must include identification of risk factors through history and examination and identification of risk of falls through an assessment tool such as gait velocity, functional reach test, timed up and go, Berg balance test, and miniBEST test. Fall prevention strategies can be single or multiple, and physical activity is the most cited. Technology can be used to detect and prevent falls. CONCLUSION: A systematic approach to the older patient in risk of falls is feasible and may impact fall prevention.

Penicillium italicum: An Underexplored Postharvest Pathogen.

In the agricultural sector, citrus is one of the most important fruit genus in the world. In this scenario, Brazil is the largest producer of oranges; 34% of the global production, and exporter of concentrated orange juice; 76% of the juice consumed in the planet, summing up US$ 6.5 billion to Brazilian GDP. However, the orange production has been considerable decreasing due to unfavorable weather conditions in recent years and the increasing number of pathogen infections. One of the main citrus post-harvest phytopathogen is Penicillium italicum, responsible for the blue mold disease, which is currently controlled by pesticides, such as Imazalil, Pyrimethanil, Fludioxonil, and Tiabendazole, which are toxic chemicals harmful to the environment and also to human health. In addition, P. italicum has developed considerable resistance to these chemicals as a result of widespread applications. To address this growing problem, the search for new control methods of citrus post-harvest phytopathogens is being extensively explored, resulting in promising new approaches such as biocontrol methods as "killer" yeasts, application of essential oils, and antimicrobial volatile substances. The alternative methodologies to control P. italicum are reviewed here, as well as the fungal virulence factors and infection strategies. Therefore, this review will focus on a general overview of recent research carried out regarding the phytopathological interaction of P. italicum and its citrus host.

Vestibular Migraine: Vestibular Symptom May Identify Different Subgroups.

OBJECTIVE: The objective of this study was to evaluate patients with vestibular migraine and analyze whether different vestibular symptoms were able to discriminate different subgroups. PATIENTS: Eighty-three patients (73 women, mean age 42 yr) who fulfilled the criteria for vestibular migraine were selected. INTERVENTION: Participants were divided into two groups according to their vestibular symptoms: spontaneous vertigo (SV) or triggered vertigo (TV). In each group, migraine subtype (migraine with aura and migraine without aura) was further analyzed. RESULTS: The SV group comprised 40 patients (35 women, mean age 42.6 yr) of which 26 had migraine with aura. The TV group comprised 43 patients (38 women, mean age 41.3 yr) of which 34 had migraine without aura. A significant difference in the presence of spontaneous vertigo was noted, proving more frequent in the migraine with aura group, whereas TV was more frequent in the migraine without aura group (χ(2) test, p < 0.0001). CONCLUSION: Spontaneous rotatory vertigo was more frequent in migraine with aura, whereas triggered nonrotatory vertigo was more frequent in migraine without aura. This finding suggests a broad spectrum of clinical symptomatology in vestibular migraine patients. All of these patients are classified as vestibular migraine but they may represent two extremes of a disease spectrum.

Correlation of impaired subjective visual vertical and postural instability in Parkinson's disease.

Perception of verticality is essential for postural control. On the other hand, postural instability is one of the cardinal features in Parkinson's disease (PD). Thus, the objective of this study was to evaluate the vertical perception using the subjective visual vertical test in PD patients with different degrees of postural instability and in different stages of disease. Forty five idiopathic PD patients were evaluated using the Unified Parkinson's Disease Rating Scale (UPDRS), the Hoehn and Yahr Scale, the clinical test for postural instability, and the subjective visual vertical test. Forty-five healthy individuals were evaluated in the control group. PD patients had a compromised perception of verticality and a disturbed processing of graviceptive pathways. Good correlation was also found between subjective visual vertical and postural instability. Patients with the worst postural instability had greater deviations of subjective visual vertical. There was also a positive correlation between subjective visual vertical and scores on the UPDRS and Hoehn and Yahr Scale, with good and reasonable degree of intensity, respectively. These findings suggest that the perception of verticality is affected in PD patients and this abnormal vertical perception and disturbed processing of graviceptive pathways are associated with postural instability and to a lesser degree with disease severity.

Psychological assessment in patients with phobic postural vertigo.

UNLABELLED: Phobic postural vertigo (PPV) is a frequent diagnosis which can be challenging to treat. OBJECTIVE: To investigate the presence of psychiatric disturbances in patients with PPV; to assess the psychological status of patients using adaptive diagnosis; to verify possible correlations between severity of psychiatric disturbance and adaptive efficacy. METHOD: A total of nineteen subjects were assessed and two instruments applied: the Primary Care Evaluation of Mental Disorders Questionnaire (PRIME-MD) and the Adaptive Operationalized Diagnostic Scale (AODS), and results from both tests were compared. RESULTS: Fourteen patients presented with mood disorder and thirteen with anxiety. All patients presented compromised adaptive efficacy. Correlation was found between overall outcome on the PRIME and the AODS (tau= -0.42, p=0.027), Separate analysis revealed correlation between results of the AODS and anxiety disorders (tau= -0.45, p=0.018) but not with mood disorders (tau= -0.36, p=0.054). CONCLUSION: Adaptive compromise was observed in individuals with PPV which was shown to be associated to psychiatric disorders.

A vertigem postural fóbica (VPF) é um diagnóstico freqüente e de tratamento difícil. OBJETIVO: Investigar a presença de distúrbios psiquiátricos em pacientes com VPF; avaliar as condições psicológicas dos pacientes através do diagnóstico adaptativo. MÉTODO: Foram avaliados 19 sujeitos e aplicados dois instrumentos de avaliação: Questionário Primary Care Evaluation of Mental Disorders (PRIME-MD) e Escala Diagnóstica Adaptativa Operacionalizada (EDAO) e comparados os resultados de ambos os testes. RESULTADOS: Quatorze pacientes apresentaram transtorno de humor e treze de ansiedade. Todos os pacientes foram avaliados com adaptação ineficaz. Houve correlação entre o resultado geral do PRIME e da EDAO (tau= -0,42, p=0,027). Ao se analisar de maneira separada, foi observada correlação entre os resultados da EDAO e os transtornos de ansiedade (tau= -0,45, p=0,018), não havendo correlação com os transtornos de humor (tau= -0,36, p=0,054). CONCLUSÃO: Há prejuízo na qualidade adaptativa das pessoas que sofrem de VPF e este prejuízo está associado a transtornos psiquiátricos.

Clinical changes of cervical dystonia pattern in long-term botulinum toxin treated patients.

Cervical dystonia (CD) is a complex disorder but the response to long-term botulinum toxin (BTX) therapy is satisfactory in most cases. Bad results are attributed by some authors to changes in muscle activation. Our purpose is to verify if the change in head deviation affects negatively the response to BTX therapy in a long-term follow-up, and if there are any differences in clinical parameters of these patients in comparison to those with stable pattern. From a total of 88 patients evaluated at the Movement Disorders Clinics of Hospital das Clinicas - University of São Paulo School of Medicine between January 1993 and December 2005, 67 were included. In 24 (35.8%) change in pattern of CD was observed, in a medium follow-up period of 80 months. The time between onset of dystonia and the diagnosis of pattern change was 9.7 years. Comparing with patients with no changes in CD pattern, there were no significant statistical differences. Improvement of symptoms around 60% was reported in both groups. In conclusion, the change in head deviation observed in CD was not responsible for bad response to therapy with BTX and there were no significant differences between both groups.

[Subjective visual vertical evaluation in normal Brazilian subjects]. / Avaliação da vertical visual subjetiva em indivíduos brasileiros normais.

Otolith function can be evaluated by subjective visual vertical (SVV) that determine the capacity of a subject to judge if the objects are on vertical position with absence of any visual reference. The aim of this study was to evaluate the SVV in a sample of normal Brazilian subjects using a portable device. Measurements of SVV were performed in 160 normal subjects (aged from 16 to 85). SVV mean value was obtained after ten adjustments. SVV mean values ranged from -2.0 degrees to +2.4 degrees (mean=0.18 degrees, and SD=0.77). Considering all age groups, there was no difference of SVV mean values (Kruskal-Wallis test; p=0.40), but older groups had a greater variance (Levene test; p=0.016). SVV values observed in this study are comparable to those described in previous studies. Although there was no difference in mean SVV-inclination according to age, there was a greater variance in older subjects.

Avaliação da vertical visual subjetiva em indivíduos brasileiros normais / Subjective visual vertical evaluation in normal Brazilian subjects

A função otolítica pode ser avaliada pela Vertical Visual Subjetiva (VVS) que determina a capacidade de um indivíduo julgar se objetos estão na posição vertical na ausência de outras referências visuais. O objetivo deste estudo foi avaliar a VVS em indivíduos brasileiros normais usando um aparelho portátil. As medidas da VVS foram realizadas em 160 indivíduos (16 a 85 anos). O valor médio da VVS foi obtido após dez ajustes. A VVS teve valores médios entre -2,0° e +2,4° (média=0,18°, e DP=0,77°). Não houve diferença entre as médias da VVS em relação à idade (teste de Kruskal-Wallis; p=0,40), mas as faixas etárias maiores tiveram variância maior (teste de Levene; p=0,016). Os valores da VVS encontrados neste estudo foram semelhantes aos registrados na literatura. Não houve diferença nas médias das inclinações da VVS de acordo com a idade, mas foi encontrada maior variância entre indivíduos mais idosos.

Avaliação da função vestibular através da vertical visual subjetiva / Vestibular function evaluation by Subjective Visual Vertical

A abordagem da função do sistema vestibular e especialmente da função otolítica pode ser avaliada pela vertical visual subjetiva (VVS) que faz o julgamento da vertical gravitacional, cuja medida é sensível para detectar lesões no sistema vestibular periférico e central. Muitos estudos relataram desvios patológicos da VVS em pacientes com lesões nas vias vestibulares e o diagnóstico topográfico incluiu lesões periféricas, de tronco cerebral, tálamo e cortex. Este artigo faz uma revisão da VVS e de sua sensibilidade para avaliar a função otolítica.

The vestibular system function approach and especially otolith function can be evaluated by subjective visual vertical (SVV) that makes the judgment of gravitacional vertical whose measurement is sensitive to detect peripheral and central vestibular system lesions. Many studies have reported pathological SVV tilts in patients with vestibular pathways lesions and the topographic diagnosis included peripheral lesions, brainstem, thalamus and cortex lesions. This article makes a review of SVV and its sensitivity to evaluate the otolith function.

[Vestibular paroxysmia: clinical study and treatment of eight patients]. / Paroxismia vestibular: estudo clínico e tratamento de oito pacientes.

Vestibular paroxysmia is a syndrome of cross-compression of the VIII cranial nerve and was first described by Jannetta who used the term "disabling positional vertigo". This syndrome is characterized by brief attacks of vertigo, tinnitus, vestibular and auditory deficits. MRI may show the VIII nerve compression from vessels in the posterior fossa, such as the basilar, vertebral, anterior-inferior cerebellar or the posterior-inferior cerebellar arteries. Vestibular paroxysmia may be treated either with medical therapy, such as carbamazepine, phenytoin or gabapentin or with the microvascular decompression of the VIII nerve. This study describes eight patients with vestibular paroxysmia. Four of them showed also clinical signs suggesting cross-compression of the V and/or VII nerve. Seven patients treated with carbamazepine had significant improvement of vertigo and tinnitus.

Paroxismia vestibular: estudo clínico e tratamento de oito pacientes / Vestibular paroxysmia: clinical study and treatment of eight patients

A paroxismia vestibular é uma síndrome de compressão do VIII nervo craniano e foi denominada inicialmente por Janetta "vertigem posicional incapacitante". Esta síndrome é caracterizada por episódios curtos de vertigem, zumbido, déficit vestibular e auditivo. A RM pode mostrar compressão do VIII nervo por vasos da fossa posterior, como a artéria basilar, artéria vertebral, artéria cerebelar inferior anterior, artéria cerebelar inferior posterior. A paroxismia vestibular pode ser tratada com terapia medicamentosa tais como carbamazepina, fenitoína ou gabapentina, ou com descompressão microvascular do VIII nervo. Este estudo descreve oito pacientes com paroxismia vestibular. Quatro deles mostraram também sinais clínicos sugerindo compressão do V e/ou VII nervos. Sete pacientes tratados com carbamazepina tiveram melhora significativa da vertigem e zumbido.

[Diagnosis and treatment of the most frequent vestibular syndromes]. / Diagnóstico e tratamento das principais síndromes vestibulares.

The aims of this study were to identify the most common vestibular syndromes in a dizziness unit, and to observe their clinical aspects and response to treatment. Five hundred and fifteen patients were studied retrospectively in two institutions. Aspects of anamnesis, physical examination and the response to treatment were evaluated. The most frequent syndromes were: benign paroxysmal positioning vertigo (VPPB) (28.5%), phobic postural vertigo (11.5%), central vertigo (10.1%), vestibular neuritis (9.7%), Meniere disease (8.5%), and migraine (6.4%). A good response to treatment was observed in most patients with migraine (78.8%), VPPB (64%), vestibular neuritis (62%), Meniere disease (54.5%) and vestibular paroxismia (54.5%). On the other hand, patients with downbeat nystagmus and bilateral vestibulopathy had poor response (52.6% and 42.8%, respectively). The diagnosis of these most frequent vestibular syndromes were established through anamnesis and physical examination (with specific clinical tests for evaluation of the vestibular function). The correct diagnosis and adequate treatment are important since these syndromes may have a good prognosis.

Diagnóstico e tratamento das principais síndromes vestibulares / Diagnosis and treatment of the most frequent vestibular syndromes

Os objetivos deste estudo foram identificar as síndromes vestibulares mais comuns nos ambulatórios de vertigem, suas características clínicas e semiológicas, e observar a resposta ao tratamento específico. Foram estudados retrospectivamente 515 pacientes atendidos em ambulatórios de duas instituições e avaliados aspectos da anamnese, exame físico e a resposta ao tratamento. As síndromes mais freqüentes foram: vertigem de posicionamento paroxística benigna (VPPB) (28,5 por cento), vertigem postural fóbica (11,5 por cento), vertigem central (10,1 por cento), neurite vestibular (9,7 por cento), doença de Menière (8,5 por cento), enxaqueca (6,4 por cento). Houve boa resposta ao tratamento nos pacientes com enxaqueca (78,8 por cento), VPPB (64 por cento), neurite vestibular (62 por cento), doença de Menière (54,5 por cento) e paroxismia vestibular (54,5 por cento), enquanto pacientes com nistagmo para baixo e vestibulopatia bilateral não tiveram resposta satisfatória (52,6 por cento e 42,8 por cento respectivamente). As síndromes vestibulares foram diagnosticadas através da anamnese e exame físico com testes clínicos específicos para avaliação da função vestibular. A identificação destas síndromes permitiu o tratamento adequado levando a uma boa evolução.
