Comparison on the clinical characteristics of patients with Takotsubo syndrome from China and from Europe/North America / 中华心血管病杂志

Objective: To summarize the clinical characteristics of patients with Takotsubo syndrome (TTS) from China and compare these features with patients from Europe/North America. Methods: We reviewed case reports published between 1990 and 2020 with the key words of "Takotsubo syndrome" "stress cardiomyopathy" "apical balloon syndrome" and "broken heart syndrome", in Wanfang, CNKI, Pubmed and Web of Science databases, and 1 294 articles were identified, including 128 articles reporting 163 cases in China and 1 166 articles reporting 1 256 cases in Europe/North America. The characteristics of demographics, triggers, symptoms, electrocardiogram, echocardiography, left ventriculogram,coronary angiography, treatment and prognosis were analyzed and compared between Chinese and European/North American cases. Results: A total of 1 294 articles (1 419 cases: 163 from China, 1 256 from Europe/North America) were included in the final analysis. The characteristics of Chinese cases included: (1) demographic:the age was (59.6±16.9) years, which was similar with that of European/North American ((59.7±17.4) years, P=0.90), and female accounting for 78.5% (128/163), which was lower than that of European/North American (85.4% (1 073/1 256), P=0.02). (2) Triggers:mental triggers accounted for 48.5% (79/163), physical triggers accounted for 43.6% (71/163), and no triggers accounted for 7.9% (13/163), respectively. Compared with Europe/North America, the ratio of patients with mental triggers was higher in China, while the ratio of patients with physical triggers and no triggers was lower (P<0.05). (3) Symptoms: chest pain (52.8% (86/163)), chest tightness (35.0% (57/163)), shortness of breath (33.1% (54/163)), dizziness (16.0% (26/163)), sweating (15.3% (25/163)), palpitations (12.3% (20/163)), syncope (9.2% (15/163)) abdominal pain/diarrhea (8.6% (14/163)), hypotension (7.4% (12/163)), and fatigue (1.2% (2/163)) were illustrated in sequence. Compared with patients in Europe/North America, the ratio of patients with chest tightness, dizziness, sweating, palpitations, abdominal pain/diarrhea was higher in Chinese patients, while the ratio of patients with hypotension was lower in Chinese patients (P<0.05). (4) Electrocardiogram: main manifestations were myocardial ischemia symptoms, such as ST-segment elevation (63.8% (104/163)), T wave inversion (46.0% (75/163)), ST-segment depression (8.6% (14/163)). Compared with European/North American, the ratio of patients with ST-segment elevation, T wave inversion, and atrioventricular block was higher in Chinese patients (P<0.05). (5) Echocardiography and imaging:apical dyskinesia (59.5% (97/163)) and apical/left ventricular bulbar dilation (36.2%(59/163)) dominated the echocardiography findings. Compared with European/North American, the ratio of patients with apical dyskinesia, apical/left ventricular bulbar dilation, and mitral regurgitation was higher in Chinese patients, while the ratio of patients with dyskinesia in other parts and left ventricular ejection fraction<50% was lower in Chinese patients (P<0.05). Left ventricular angiography showed 36.2% (59/163) of apical dyskinesia in Chinese patients, which was higher than that reported in European/North American patients, and 38.7% (63/163) of apical/left ventricular bulbar dilation was reported in Chinese patients, which was similar to that reported in European/North American patients. Coronary angiography showed percent of no stenosis or stenosis less than 50% was 87.1% (142/163), which was similar to that reported in European/North American patients (P>0.05). The typical type of TTS accounted for 96.3% (157/163), which was significantly higher than that reported in European/ American patients, while the ratio of basal type and midventricular type was lower (P<0.01). (6) Treatment and prognosis:the applied drugs in China were listed in order as following, β-blockers (41.1% (67/163)), antiplatelet agents (37.4%(61/163)), ACEI/ARB (36.2%(59/163)), anticoagulants (27.0%(44/163)), diuretics (19.6% (32/163)), etc. Compared with Europe/North America, the ratio of antiplatelet agents, anticoagulants, statins, diuretics, and nitrates use was higher in China (P<0.05), while the use of oxygen therapy and IABP was similar (P>0.05). The hospital mortality in China was 5.5% (9/163), during 1-year follow-up the recurrence rate was 3.7% (6/163) and the mortality was 0. The prognosis was similar with that in Europe/North America. Conclusions: Compared with TTS cases in Europe/North America, TTS cases in China also occur usually in middle-aged and elderly women, most of whom have mental/physical triggers and typical imaging manifestations, followed by a low hospital mortality rate and recurrence rate.

Severe Dizziness Related to Postural Instability, Changes in Gait and Cognitive Skills in Patients with Chronic Peripheral Vestibulopathy

Abstract Introduction Peripheral vestibular disorders can lead to cognitive deficits and are more common in elderly patients. Objective To evaluate and correlate cognitive, balance and gait aspects in elderly women with chronic peripheral vestibular dizziness, and to compare them with elderly women without vestibular disorders. Methods Twenty-two women presenting peripheral vestibular dizziness episodes for at least six months participated in the study. The individuals were categorized by dizziness severity level: moderate (n = 11) or severe (n = 11). The control group (n = 11) included women showing no vestibulopathy, light-headedness or dizziness. Cognitive assessments and semi-static and dynamic balance assessments were performed with the Balance Master (Neurocom International, Inc., Clackamas, OR), while the Dizziness Handicap Inventory provided a score for the severity of the symptoms. The groups were submitted to statistics of inference and correlation between cognitive, balance and stability variables. Results The group with severe dizziness showed higher sway speed of the center of pressure in the anteroposterior direction, smaller step length, and slower gait than the control group. Regarding the cognitive variables, the group with severe dizziness symptoms presented significant correlations with stability and gait variables. Conclusion The relationship between cognitive aspects, balance and gait was stronger in women with severe dizziness than in those with no vestibulopathy.

Vestibular migraine: diagnosis challenges and need for targeted treatment / Migrânea vestibular: desafios diagnósticos e a necessidade de tratamentos específicos

ABSTRACT Approximately 1% of the general population suffers from vestibular migraine. Despite the recently published diagnostic criteria, it is still underdiagnosed condition. The exact neural mechanisms of vestibular migraine are still unclear, but the variability of symptoms and clinical findings both during and between attacks suggests an important interaction between trigeminal and vestibular systems. Vestibular migraine often begins several years after typical migraine and has a variable clinical presentation. In vestibular migraine patients, the neurological and neurotological examination is mostly normal and the diagnosis will be based in the patient clinical history. Treatment trials that specialize on vestibular migraine are scarce and therapeutic recommendations are based on migraine guidelines. Controlled studies on the efficacy of pharmacologic interventions in the treatment of vestibular migraine should be performed.

RESUMO Cerca de 1% da população apresentam o diagnóstico de migrânea vestibular. Apesar dos critérios diagnósticos terem sido publicados recentemente, ainda é uma condição subdiagnosticada. Os mecanismos neurais exatos da migrânea vestibular ainda não estão claros, mas a variabilidade dos sintomas e achados clínicos durante e entre os ataques sugere uma interação importante entre os sistemas trigeminal e vestibular. A migrânea vestibular geralmente começa alguns anos após a migrânea típica e tem apresentação clínica variável. Em pacientes com migrânea vestibular, o exame neurológico e otoneurológico são geralmente normais e o diagnóstico é baseado na história clínica do paciente. Estudos sobre tratamento da migrânea vestibular são escassos e recomendações terapêuticas são baseadas em diretrizes do tratamento da migrânea. Estudos controlados sobre a eficácia das intervenções farmacológicas para o tratamento da migrânea vestibular devem ser realizados.

Imipramine for vestibular dysfunction in panic disorder: a prospective case series / Imipramina para disfunção vestibular em transtorno do pânico: uma série de casos prospectiva

OBJECTIVE: The purpose of this study was to evaluate the efficacy and effectiveness of imipramine on the treatment of comorbid chronic dizziness and panic disorder. METHOD: Nine patients with panic disorder and agoraphobia associated with chronic dizziness underwent otoneurological screening and were treated with a 3-months course of imipramine. Anxiety levels were measured with the Hamilton Anxiety Scale (HAM-A), dizziness levels were evaluated using the Dizziness Handicap Inventory (DHI), and panic severity and treatment outcome were assessed with the Clinical Global Impression Scale (CGI). RESULTS: At the baseline 33.3 percent (n=3) had a bilateral peripheral deficit vestibulopathy, the mean scores for HAM-A were 27.2±10.4, for DHI were 51.7±22.7, and for CGI-S were 4.8±0.9. All patients had a significant reduction in their HAM-A (11.1±5.5, p=0.008), DHI (11.5±8.1, p=0.008) and CGI-I (1.8±0.7, p=0.011) levels after 3-months imipramine treatment (mean=72.2±23.2 mg/day). CONCLUSION: This study found a decrease in anxiety levels and in the impact of dizziness in the patients' quality of life after a 3-months treatment course with imipramine.

OBJETIVO: O objetivo deste estudo foi avaliar a eficácia e efetividade da imipramina no tratamento da tontura crônica e do transtorno de pânico comórbidos. MÉTODO: Nove pacientes com transtorno do pânico e agorafobia associada com tontura crônica foram submetidos à avaliação otoneurológica e tratados durante 3 meses com imipramina. Os níveis de ansiedade foram medidos através da Escala Hamilton de Ansiedade (HAM-A); os de tontura foram avaliados usando o Dizziness Handicap Inventory (DHI), e a gravidade do pânico e sua resposta pela Escala de Impressão Clínica Global (CGI). RESULTADOS: Na avaliação inicial, 33,3 por cento (n=3) da amostra apresentavam vestibulopatia periférica deficitária bilateral; as médias foram: da HAM-A 27,2±10,4, do DHI 51,7±22,7 e do CGI-S 4,8±0,9. Todos tiveram uma redução significativa nos escores de HAM-A (11,1±5,5, p=0,008), DHI (11,5±8,1, p=0,008) e CGI-I (1,8±0,7, p=0,011), após 3 meses de tratamento com imipramina (média=72,2±23,2 mg/dia). CONCLUSÃO: Este estudo encontrou uma diminuição dos níveis de ansiedade e do impacto da tontura na qualidade de vida dos pacientes após um curso de 3 meses de tratamento com imipramina.

Fall Risk in Low-Income Elderly People in One Urban Area

PURPOSE: The purpose of this study was to investigate the factors that increase of the risk for falls in low-income elders in urban areas. METHODS: The participants were elderly people registered in one of public health centers in one city. Data were collected by interviewing the elders, assessing their environmental risk factors, and surveying relevant secondary data from the public health center records. For data analysis, descriptive statistics and multiple logistic regression were performed using SPSS version 14. RESULTS: Stroke, diabetes, visual deficits, frequency of dizziness, use of assistive devices and moderate depression were statistically significant risk factors. The comorbidity of chronic diseases with other factors including depression, visual deficit, dizziness, and use of assistive devices significantly increased the risk of falls. From multiple logistic regression analysis, statistically significant predictors of falls were found to be stroke, total environmental risk scores, comorbiditiy of diabetes with visual deficits, and with depression. CONCLUSION: Fall prevention interventions should be multifactorial, especially for the elders with stroke or diabetes, who were identified in this study as the high risk group for falls. A fall risk assessment tool for low-income elders should include both the intrinsic factors like depression, dizziness, and use of assistive devices, and the extrinsic factors.

Versão brasileira do Dizziness Handicap Inventory / Brazilian version of the Dizziness Handicap Inventory

TEMA: impacto da tontura na qualidade de vida (QV). OBJETIVO: adaptar culturalmente o Dizziness Handicap Inventory (DHI) para aplicação na população brasileira, avaliar sua reprodutibilidade e descrever os resultados obtidos à aplicação deste questionário em pacientes com tontura crônica. MÉTODO: o DHI foi aplicado, inicialmente, em 45 pacientes com tontura crônica e hipótese diagnóstica de síndrome vestibular, seguindo as etapas de tradução do idioma Inglês para o Português e adapatação lingüística, revisão da equivalência gramatical e idiomática, adaptação cultural e avaliação da reprodutividade intra e interpesquisadores. A avaliação da reprodutividade foi realizada por intermédio do teste de pesquisadores. A avaliação da reprodutividade foi realizada por intermédio do teste de Wilcoxon para duas amostras dependentes, P < 0,05. O instrumento foi aplicado para um total de 250 pacientes para avaliação do impacto da tontura na qualidade de vida de vestibulopatas crônicos. RESULTADOS: a versão brasileira do DHI (DHI brasileiro) foi bem compreendida pelo população estudada. Não foi verificada diferença estatística significante à avaliação da reprodutibilidade inter-pesquisadores (P = 0,418) e intra-pesquisadores (P = 0,244). Todos pacientes apresentaram prejuízo na QV e os aspectos físicos foram os mais prejudicados, seguidos em ordem decrescente pelos aspectos funcionais e emocionais. Os aspectos funcionais mostraram-se mais comprometidos em indivíduos mais velhos. Nenhuma associação foi verificada entre o gênero e as médias do escore total e de cada um dos aspectos avaliados pelo DHI. CONCLUSÃO: o DHI foi adaptado culturalmente para aplicação na população brasileira (DHI brasileiro), mostrando-se confiável para a avaliação da interferência da tontura na QV. Os pacientes com tontura crônica e hipótese diagnóstica de síndrome vestibular apresentaram prejuízo na QV devido a este sintoma, verificados à aplicação do DHI brasileiro. Os aspectos...

BACKGROUND: impact of dizziness on life quality (LQ). AIM: to adapt the Dizziness Handicap Inventory (DHI) for application in the Brazilian population; to assess its reproducibility; and to describe the results obtained in patients with chronic dizziness. METHOD: The DHI was initially applied in 45 patients with chronic dizziness and with a clinical diagnosis of vestibular syndrome. The application followed the stages of translation - from English to Portuguese - and linguistic adaptation, grammatical and idiomatic equivalence review and evaluation of its intra and inter-researchers reproducibility. Reproducibility was assessed by using the Wilcoxon Test for two dependent samples, P < 0.05. The questionnaire was applied on 250 patients with chronic vestibular syndrome in order to evaluate the impact of dizziness on LQ. RESULTS: The Brazilian version of the DHI (Brazilian DHI) was well comprehended by the studied population and no statistically significant difference was found in the inter-researcher (P = 0.418) and intra-researcher (P = 0.244) reproducibility. All of the studied patients presented a loss in LQ due to dizziness. Aspects which were most affected were the physical ones, followed by, in a decreasing order, the functional and the emotional ones. Functional aspects were more compromised in older individuals. No association was verified between gender and the overall mean scores of the DHI and between gender and the mean scores of each aspect assessed by the DHI. CONCLUSION: the DHI was culturally adapted for application in the Brazilian population (Brazilian DHI). This instrument was considered to be a reliable tool to evaluate the impact of dizziness on LQ. Patients with chronic dizziness and with clinical diagnosis of vestibular syndrome presented a loss in LQ, due to this symptom. This loss was verified by the application of the Brazilian DHI. Physical aspects were the most compromised.

Neurinoma del acústico : pautas de diagnóstico, tratamiento y resultados quirúrgicos / Acoustic neurinoma : guidelines of diagnosis, treatment and surgical results

Es propósito de esta publicación difundir la metodología empleada en el estudio y tratamiento del neurinoma del acústico en 104 pacientes operados durante el período 1991 a 1994. Ante diagnóstico presuntivo de neurinoma del acústico debe solicitarse: audiometría tonal, logoaudiometría, potenciales evocados de tronco encefálico y estudios por imágenes. Actualmente se utiliza la resonancia magnética por imágenes en cortes axiales, coronales y sagitales con gadolinio, como primer y definitivo estudio por la confiabilidad diagnóstica. Reservamos la Tomografía Computada de alta resolución con contraste iodado endovenoso de cerebro y fosa posterior, para los pacientes de 3a. edad pues de no poder identificarse un tumor intracanalicular, la expectativa de crecimiento en relación al promedio de vida no compromete al paciente. En nuestra casuística de 104 tumores el 30,7 por ciento tenían un tamaño de más de 3 cm. en A.P.C. No hubo mortalidad en esta serie. Un paciente presentó hematoma del A.P.C. y debió ser intervenido de inmediato para su evacuación, quedando sin secuelas neurológicas. El análisis de la función facial al despertar en tumores de hasta 2 cm. en el A.P.C. (39,4 por ciento) fue: el 95.2 por ciento normal; 4.8 por ciento paresia; 0 por ciento parálisis. De 6 fístulas de líquido cefalorraquídeo, 5 cedieron con tratamiento médico y 1 se reoperó. Hubo 4 casos de meningitis que se presentaron entre el 4§ y 8§ día post-operatorio, que respondieron al tratamiento antibiótico instituído. La resección tumoral total se logró en el 100 por ciento de los tumores de hasta 2 cm. y en el 92 por ciento de los tumores grandes y gigantes. Se concluye que a mayor tamaño tumoral los resultados decrecen en cuanto a posibilidad de preservar audición, y se incrementa la morbilidad sobre el facial y otras estructuras nerviosas. En nuestra casuística debido al gran número de tumores grandes y gigantes (60.5 por ciento), y de aquellos con mala audición preoperatoria; lo cual la mayoría de los pacientes fueron abordados por las vías laterales (translaberíntica-translaberíntica ampliada y trasntemporal total). Se remarca la vital importancia en esta patología de arribar al diagnóstico lo más temprano posible para disminuir la morbilidad que aumenta en proporción directa al incremento del tamaño del tumor.
