ABSTRACT
Intolerance to orthostasis encompasses a group of responses on assumption of upright posture. One such response is postural dysautonomia. One of the types of postural dysautonomia is postural orthostatic tachycardia syndrome, which is characterised by an increase in heart rate of more than 30 bpm without hypotension along with other features of dysautonomia on attaining an erect posture, either actively or passively. This paper brings out a case of postural dysautonomia in a pilot aspirant in response to Head-up tilt (HUT) test. A 23-year-old female military pilot aspirant reported for evaluation of Syncope and Air Sickness. She gave a history of solitary episode of loss of consciousness on ground while preparing for an early morning sortie. She was diagnosed with a case of neurocardiogenic syncope and was put back to flying training. Subsequently, after about 2 months, she developed features of air sickness while flying and also could not tolerate preliminary motion sickness desensitisation at her unit. A thorough medical evaluation failed to reveal any neurocardiological abnormality. Before commencing the air sickness desensitisation protocol at the Institute of Aerospace Medicine, she was subjected to HUT during which she developed signs and symptoms suggestive of postural dysautonomia. A test retest assessment with repeat HUT and passive standing test revealed similar responses.
ABSTRACT
Objective: To observe the effect of the combination of acupuncture and medication on orthostatic hypotension after incomplete cervical spinal cord injury. Methods: Ninety-two patients with orthostatic hypotension after incomplete cervical spinal cord injury were divided into two groups according to the random number table method, with 46 cases in each group. The control group was treated with oral midodrine hydrochloride on the basis of conventional treatment, and the observation group was treated with acupuncture in addition to the intervention used in the control group. Both groups were treated for 4 weeks. The changes in supine and orthostatic blood pressures, motor and sensory scores, quadriplegic function index score, clinical efficacy, and safety evaluation were observed. Results: During the treatment, 2 cases dropped out in the observation group, and 3 cases dropped out in the control group. After 4 weeks of treatment, the clinical efficacy of the observation group was better than that of the control group (P<0.05). After treatment, the supine systolic blood pressure and diastolic blood pressure in the two groups had no significant changes (P>0.05), while the orthostatic systolic blood pressure and diastolic blood pressure, the motor and sensory scores, and the quadriplegic function index score were significantly higher than those before treatment (P<0.05), and the scores in the observation group were higher than those in the control group (P<0.05). Adverse reactions were mild in both groups. Conclusion: The combination of acupuncture and medication can significantly improve the orthostatic blood pressure, motor and sensory function and daily living ability of patients with orthostatic hypotension after incomplete cervical spinal cord injury, and it is safe and reliable.
ABSTRACT
Objective:To investigate the clinical characteristics of circadian rhythm disorder of blood pressure and its impact on orthostatic hypotension (OH) in Parkinson′s disease (PD).Methods:A total of 165 PD patients from Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from August 2019 to October 2021 were consecutively enrolled. Medical history and scores of motor and non-motor symptoms of patients were collected. Twenty-four-hour ambulatory blood pressure and OH data were collected, and the OH questionnaire was completed. The incidence of each type of circadian rhythm disorder of blood pressure was investigated. The t test, chi-square test and Mann-Whitney U test were used to determine between-group differences of circadian rhythm disorder of blood pressure. The linear trends in clinical characteristics were tested by linear regression analysis. Logistic regression analysis was used to analyze the relationship between different circadian rhythm disorders of blood pressure and OH as well as symptomatic OH (SOH). Results:In 165 PD patients, the incidence of reverse dipping pattern was 39.39% (65/165), nocturnal hypertension was 43.64% (72/165), and awakening hypotension was 31.52% (52/165). Compared with patients without reverse dipping pattern, patients with reverse dipping pattern were older [(71.72±7.81) years vs (65.29±9.68) years, t=-4.491, P<0.001], had later onset age [(66.67±9.10) years vs (62.16±10.66) years, t=-2.809, P=0.006], longer duration [36.00(20.50, 95.50) months vs 24.00(12.00, 41.75) months, Z=-3.393, P<0.001], higher dose of levodopa (LD) [(426.15±267.38) mg/d vs (284.00±235.58) mg/d, t=-3.590, P<0.001], higher levodopa equivalent dose (LED) [(514.80±360.03) mg/d vs (341.44±284.57) mg/d, t=-3.440, P=0.001], higher Unified Parkinson′s Disease Rating Scale (UPDRS)-Ⅱ scores (12.92±6.38 vs 9.54±5.59, t=-3.434, P=0.001), higher UPDRS-Ⅲ scores (28.34±11.60 vs 21.41±12.18, t=-3.508, P=0.001) and higher percentages of hallucinations [18.46% (12/65) vs 7.00% (7/100), χ2 =5.079, P=0.024]. Compared with patients without awakening hypotension, patients with awakening hypotension were older [(70.83±7.09) years vs (66.44±10.16) years, t=-2.811, P=0.006]. Compared with patients without nocturnal hypertension, patients with nocturnal hypertension had longer duration [39.50(15.00, 96.00) months vs 24.00 (12.00, 36.00) months, Z=-2.944, P=0.003], higher LD [(398.61±251.19) mg/d vs (294.62±254.25) mg/d, t=-2.619, P=0.010], higher LED [(493.28±344.02) mg/d vs (345.05±298.59) mg/d, t=-2.959, P=0.004], higher percentages of hallucinations [19.44% (14/72) vs 5.38% (5/93), χ2 =7.882, P=0.005], higher UPDRS-Ⅱ scores (12.08±6.33 vs 10.00±5.86, t=-2.086, P=0.039), higher UPDRS-Ⅲ scores (26.50±11.72 vs 22.42±12.66, t=-2.034, P=0.044), and greater blood pressure variability (BPV) (20.66±5.47 vs 17.44±5.36, t=-3.798, P<0.001). Trend analysis showed that the variety of circadian rhythm was positively correlated with age and duration, use of levodopa and monoamine oxidase B inhibitors and amantidine, morning and daily LD and LED, UPDRS-Ⅱ, UPDRS-Ⅲ and Hamilton Anxiety Scale scores, hallucinations, OH and SOH, and BPV in PD ( P<0.05). Multivariate Logistic regression analysis showed that awakening hypotension ( OR=3.35, 95% CI 1.55-7.22, P=0.002) and nocturnal hypertension ( OR=2.44, 95% CI 1.20-4.97, P=0.014) were risk factors for OH, and LED ( OR=1.21, 95% CI 1.01-1.43, P=0.035), UPDRS-Ⅲ scores ( OR=1.09, 95% CI 1.02-1.16, P=0.009) and w-BPV ( OR=1.14, 95% CI 1.01-1.29, P=0.029) were independent risk factors for SOH. Conclusions:Circadian rhythm disorder of blood pressure was correlated with age, duration, severity of motor symptoms. Awakening hypotension and nocturnal hypertension are independent risk factors for OH in PD.
ABSTRACT
Orthostatic intolerance is a syndrome characterized by a series of symptoms that occur when standing upright, resulting in the loss of ability to maintain an upright position.This condition can be further classified into orthostatic hypotension, postural orthostatic tachycardia syndrome, and vasovagal syncope.Some scholars suggest that orthostatic hypertension may also be considered a part of this syndrome.The most significant risk associated with orthostatic intolerance is falls, which can lead to physical injury and psychological distress.This article aims to review the advancements made in the diagnosis and treatment of orthostatic intolerance, so as to enhance the standardization of clinical diagnosis and improve the effectiveness of treatment.
ABSTRACT
@#Vitamin B12 deficiency has long been known to present with various neurological manifestations, but only rarely presents as movement disorders, especially in adults. We present the case of a 30-year-old vegan male presenting with tremors on both legs when standing which was relieved by vitamin B12 supplementation. To the best of our knowledge, this is the first documented case of slow orthostatic tremor or pseudo-orthostatic tremor caused by vitamin B12 deficiency.

Spontaneous intracranial hypotension (SIH) is a rare and debilitating condition caused by decreased intracranial pressure, which occurs more frequently in females. SIH can have several causes, among them the spontaneous formation of cerebrospinal fluid venous fistula (CSF-venous fistula), which is primarily responsible for the appearance of postural headache. Orthostatic headache is diagnosed by CSF pressure < 6 mmHg associated with specific imaging findings. Other specific symptoms such as dizziness, reduced muscle strength, blurred vision and syncope and other more systemic symptoms such as fatigue, mental confusion and difficulty concentrating are commonly observed. Etiological investigation through imaging studies such as magnetic resonance imaging and dynamic tomography of myelography is necessary for diagnosis. Due to the debilitating condition, several therapeutic approaches have been developed, ranging from more conservative approaches, with observation and use of analgesics, to more invasive interventions such as surgical ligation, transvenous embolization and blood tamponade.
A hipotensão intracraniana espontânea (HIH) é uma condição rara e debilitante causada pela diminuição da pressão intracraniana, que ocorre com mais frequência em mulheres. A HIE pode ter diversas causas, entre elas a formação espontânea de fístula venosa do líquido cefalorraquidiano (fístula liquórica-venosa), principal responsável pelo aparecimento da cefaleia postural. A cefaleia ortostática é diagnosticada pela pressão liquórica < 6 mmHg associada a achados de imagem específicos. Outros sintomas específicos como tontura, redução da força muscular, visão turva e síncope e outros sintomas mais sistêmicos como fadiga, confusão mental e dificuldade de concentração são comumente observados. A investigação etiológica por meio de exames de imagem como ressonância magnética e tomografia dinâmica da mielografia é necessária para o diagnóstico. Devido ao quadro debilitante, diversas abordagens terapêuticas têm sido desenvolvidas, desde abordagens mais conservadoras, com observação e uso de analgésicos, até intervenções mais invasivas como ligadura cirúrgica, embolização transvenosa e tamponamento sanguíneo.
ABSTRACT
Abstract Background The neurological manifestations in COVID-19 adversely impact acute illness and post-disease quality of life. Limited data exist regarding the association of neurological symptoms and comorbid individuals. Objective To assess neurological symptoms in hospitalized patients with acute COVID-19 and multicomorbidities. Methods Between June 2020 and July 2020, inpatients aged 18 or older, with laboratory-confirmed COVID-19, admitted to the Hospital São Paulo (Federal University of São Paulo), a tertiary referral center for high complexity cases, were questioned about neurological symptoms. The Composite Autonomic Symptom Score 31 (COMPASS-31) questionnaire was used. The data were analyzed as a whole and whether subjective olfactory dysfunction was present or not. Results The mean age of the sample was 55 ± 15.12 years, and 58 patients were male. The neurological symptoms were mostly xerostomia (71%), ageusia/hypogeusia (50%), orthostatic intolerance (49%), anosmia/hyposmia (44%), myalgia (31%), dizziness (24%), xerophthalmia (20%), impaired consciousness (18%), and headache (16%). Furthermore, 91% of the patients had a premorbidity. The 44 patients with subjective olfactory dysfunction were more likely to have hypertension, diabetes, weakness, shortness of breath, ageusia/hypogeusia, dizziness, orthostatic intolerance, and xerophthalmia. The COMPASS-31 score was higher than that of previously published controls (14.85 ± 12.06 vs. 8.9 ± 8.7). The frequency of orthostatic intolerance was 49% in sample and 63.6% in those with subjective olfactory dysfunction (2.9-fold higher risk compared to those without). Conclusion A total of 80% of inpatients with multimorbidity and acute COVID-19 had neurological symptoms. Chemical sense and autonomic symptoms stood out. Orthostatic intolerance occurred in around two-thirds of the patients with anosmia/hyposmia. Hypertension and diabetes were common, mainly in those with anosmia/hyposmia.
Resumo Antecedentes As manifestações neurológicas na COVID-19 impactam adversamente na enfermidade aguda e na qualidade de vida após a doença. Dados limitados existem em relação a associação de sintomas neurológicos e indivíduos com comorbidades. Objetivo Avaliar os sintomas neurológicos em pacientes de hospitalizados com COVID-19 aguda e múltiplas comorbidades. Métodos Entre junho e julho de 2020, pacientes de hospitais com idade 18 anos ou acima e COVID-19 laboratorialmente confirmada, admitidos no Hospital São Paulo (Universidade Federal de São Paulo), um centro de referência terciário para casos de alta complexidade, foram perguntados sobre sintomas neurológicos. O questionário Pontuação composta de sintoma autonômico (COMPASS-31) foi usado. Os dados foram analisados no geral e se a disfunção olfatória subjetiva estava presente ou não.

Os sintomas neurológicos foram principalmente xerostomia (71%), ageusia/hipogeusia (50%), intolerância ortostática (49%), anosmia/hiposmia (44%), mialgia (31%), tontura (24%), xeroftalmia (20%), comprometimento na consciência (18%) e cefaleia (16%). Além disso, 91 % dos pacientes tinham uma pré-morbidade. Os 44 pacientes com disfunção olfatória tinham maior chance de ter hipertensão, diabetes, fraqueza, falta de ar, ageusia/hipogeusia, tontura, intolerância ortostática e xeroftalmia. A pontuação do COMPASS-31 foi maior do que a de controles previamente publicados (14,85 ± 12,06 vs. 8,9 ± 8,7). A frequência de intolerância ortostática foi 49% na amostra e 63,6% naqueles com disfunção olfatória subjetiva (risco 2.9 vezes maior comparado com os sem). Conclusão Um total de 80% dos pacientes hospitalizados com múltiplas morbidades e COVID-19 aguda tinham sintomas neurológicos. Os sintomas do sentido químico e autonômicos se destacaram. A intolerância ortostática ocorreu em cerca de dois terços dos pacientes com anosmia/hiposmia. A hipertensão e o diabetes foram comuns, principalmente naqueles com anosmia/hiposmia.
ABSTRACT
Introducción: El síndrome de cascanueces se considera una anomalía infrecuente y poco pensada en la práctica médica; su incidencia no está bien establecida debido a su sintomatología variada. La agenesia renal unilateral se estima entre 1/2500 y 1/4000 nacidos vivos. Objetivos: Describir una paciente de 18 años con sospecha prenatal de agenesia renal derecha confirmada por imágenes después del nacimiento, que ingresó por proteinuria. Presentación del caso: Paciente de 18 años con agenesia renal derecha conocida, en la que un examen de orina detectó proteinuria desde los 13 años. En su estudio se clasificó como proteinuria ortostática y evolutivamente refirió dolor lumbar izquierdo ligero y transitorio. En el ultrasonido renal, realizado para valorar crecimiento del riñón único, se detectó dilatación de la vena renal izquierda. Se repitió el estudio ecográfico para precisar ángulo aorto-mesentérico y dilatación de vena renal izquierda, y se confirmó el síndrome de cascanueces. Conclusiones: La asociación entre agenesia renal derecha y síndrome de cascanueces, resulta extremadamente rara, y, cuando se presenta con proteinuria ortostática y dolor lumbar ocasional, debe seguirse en forma expectante, pero no se necesita tratamiento quirúrgico en la mayoría de los casos.
Introduction: Nutcracker syndrome is considered an infrequent and poorly thought out anomaly in medical practice; its incidence is not well established due to its varied symptomatology. Unilateral renal agenesis is estimated to be between 1/2500 and 1/4000 live births. Objectives: To describe an 18-year-old female patient with suspected pre-natal imaging-confirmed right renal agenesis after birth, who was admitted due to proteinuria. Case presentation: An 18-year-old female patient with known right renal agenesis, in whom a urine test detected proteinuria from the age of 13. In the study it was classified as orthostatic proteinuria and evolutionarily she referred mild and transient left low back pain. Renal ultrasound, performed to assess single kidney growth, showed dilation of the left renal vein. The ultrasound study was repeated to specify aorto-mesenteric angle and left renal vein dilation, and nutcracker syndrome was confirmed. Conclusions: The association between right renal agenesis and nutcracker syndrome is extremely rare, and, when it presents with orthostatic proteinuria and occasional low back pain, it should be followed expectantly, but surgical treatment is not needed in most cases.
ABSTRACT
La hipotensión intracraneal espontánea (SIH) es una patología con una incidencia anual aproximada de 5 por cada 100.000 personas al año, caracterizada clásicamente por cefalea ortostática comúnmente secundaria a una fuga espontánea de líquido cefalorraquídeo (LCR), pudiendo existir a su vez una amplia gama de síntomas asociados. El diagnóstico se centra en la clínica y en hallazgos típicos en la resonancia nuclear magnética (RM), sin embargo, según diversos estudios, puede corresponder a una patología subdiagnosticada por la dificultad que ha existido en definir criterios diagnósticos universales y un manejo terapéutico estandarizado, el cual varía inicialmente entre manejo médico conservador y/o parches de sangre epidural (PHE). Reportamos el caso de una paciente femenina de 51 años quien fue atendida en el Hospital Herminda Martin de Chillán donde se realizó el diagnóstico y tratamiento sintomático con PHE.
Spontaneous intracranial hypotension (SIH) is a pathology with an annual incidence of approximately 5 per 100,000 people per year, classically characterized by orthostatic headache commonly secondary to a spontaneous cerebrospinal fluid (CSF) leak, and there may also be a wide range of of associated symptoms. The diagnosis is centered on the clinic and on typical findings in magnetic resonance imaging (MRI), however, according to various studies, it may correspond to an underdiagnosed pathology due to the difficulty that has existed in defining universal diagnostic criteria and standardized therapeutic management. which initially varies between conservative medical management and/or epidural blood patches (PHE). We report the case of a 51-year-old female patient who was treated at the Herminda Martin de Chillán Hospital where the diagnosis and symptomatic treatment with PHE were made.
ABSTRACT
Neurogenic orthostatic hypotension （nOH） is a common neurodegenerative disease， and is usually differentiated as kidney-yang depletion syndrome in traditional Chinese medicine （TCM）. Fire needling on governor vessel （督脉） acupoints as well as Shenshu （BL 23） and Zhishi （BL 52） can dredge the qi and blood of governor vessel， so as to warm yang and unblock the channels， supplement essence and boost marrow. A case of elderly nOH treated by fire needling mainly at governor vessel points， Shenshu （BL 23） and Zhishi （BL 52） was reported. After nearly two months of treatment， the patient's orthostatic blood pressure difference and yang deficiency-related symptoms were significantly improved， and the results of blood pressure monitoring， TCM syndrome scale evaluation and Shenshu （BL 23） area infrared imager detection all showed definite clinical effect.
ABSTRACT
RESUMEN INTRODUCCIÓN: La enfermedad de Parkinson es un trastorno neurodegenerativo frecuente que se caracteriza por manifestaciones de tipo motor y no motor, tales como disautonomía, trastornos del sueño, disfunción sexual, alteraciones psiquiátricas y cognitivas, entre otros. Según su fenotipo motor, se puede clasificada en tremórica dominante (TD), dificultad para la marcha/inestabilidad postural (DMI) y un fenotipo indeterminado. En el estudio se determina la influencia del fenotipo motor en la disautonomía cardiovascular del paciente con Parkinson en los pacientes de la consulta de neurología del hospital del IVSS "Dr. Patrocinio Peñuela Ruiz" entre mayo del 2015 y abril del 2016. METODOS: Estudio observacional, descriptivo, transversal en pacientes mayores de 40 años con EP idiopática. Se evaluó el MDS-UPDRS, Hoehn y Yahr, Scopa-AUT , Hipotensión Ortostática y Rines-Valcardi. RESULTADOS: Se obtuvo una muestra de 57 pacientes; luego de la aplicación de los criterios de inclusión y exclusión se estudiaron 37 sujetos. Todos los pacientes tuvieron algún grado de disautonomía (medida con la escala Scopa-AUT). El Scopa-AUT fue mayor en los pacientes con hipotensión ortostática (p = ,003), observándose igual diferencia para la subescala cardiovascular (p = ,026). Se observó que la neuropatía autonómica (medida con Rines-Valcardi) fue más frecuente en aquellos pacientes con fenotipo DMI (p = < ,001), y que la hipotensión ortostática fue también más frecuente en aquellos pacientes con dicho fenotipo (DMI) (p = ,016). CONCLUSIÓN: La presencia de disautonomía es frecuente en los pacientes con EP; hubo diferencias en la puntuación total y la subescala cardiovascular del Scopa-AUT, de acuerdo CON la presencia de hipotensión ortostática; aquellos sujetos que cursan con fenotipo motor DMI tienen mayor riesgo de presentar hipotensión ortostática y neuropatía autonómica cardíaca.
ABSTRACT INTRODUCTION: Parkinson's disease is a frequent neurodegenerative disorder characterized by motor and non-motor manifestations, such as dysautonomia, sleep disorders, sexual dysfunction, and psychiatric and cognitive disorders. It can be classified according to their motor phenotype in tremor-dominant (TD), postural instability/gait difficulty (DMI), and indeterminate subtypes. This study established the influence of motor phenotype on the cardiovascular dysautonomia of patients with Parkinson's disease from the neurology outpatient clinic at the IVSS hospital "Dr. Patrocinio Peñuela Ruiz," from May 2015 to April 2016. METHODS: Observational, descriptive, cross-sectional study in patients older than 40 years with idiopathic PD. The MDS-UPDRS scale, Hoehn and Yahr scale, Scopa-AUT scale, Orthostatic Hypotension, and RINES-VALCARDI were evaluated. RESULTS: A sample of 57 was obtained, and after applying inclusion and exclusion criteria, 37 subjects were studied. All the patients had some degree of dysautonomia (measured with SCOPA- AUT scale). The SCOPA-AUT was higher in patients with orthostatic hypotension (p= .003), finding this same difference for the cardiovascular subscale (p = .026). Both autonomic neuropathy (measured with RINES-VALCARDI) and orthostatic hypotension were found more frequently on the DMI phenotype (p= <.001 and p=.016). CONCLUSION: Dysautonomia is frequent in PD patients; there was a difference between SCOPA-AUT total score and cardiovascular subscale according to orthostatic hypotension; those with DMI phenotype have a greater risk of orthostatic hypotension and cardiac autonomic neuropathy.

Background: Orthostatic hypotension (OH) increases the risk of falls and associated morbidity and mortality in elderly. Hence, determining the prevalence of OH and its associated factors is important, especially in understudied LMIC settings. Methods: A community-based cross-sectional study was conducted among randomly selected 240 community-dwelling elderly from Thiruvananthapuram, Kerala. The OH symptoms were assessed by standard clinical measurements and frailty was assessed by modified Fried frailty phenotype. Logistic regression analysis was conducted to assess the factors associated with OH. Results: The prevalence of OH and frailty among participants was 9.6 and 29.2 percent respectively. In the first minute, OH was associated with increased odds of falls (OR ¼ 1.97 [95%CI ¼ 1.05, 3.72]). Increase in number of co-morbidities (ORadj ¼ 1.82 [95%CI ¼ 1.36, 2.48]), number of medicines used (ORadj ¼ 1.73 [95%CI ¼ 1.28, 2.34]), and orthostatic intolerance (ORadj ¼ 3.67 [95%CI ¼ 1.13, 11.94]) increased the odds of having OH. Elderly with diabetes (ORadj ¼ 4.81 [95%CI ¼ 1.57, 14.77]), hypertension (ORadj ¼ 4.97 [95% CI ¼ 1.01, 24.46]) and cognitive impairment (ORadj ¼ 5.01 [95%CI ¼ 1.40, 18.51]) were at a higher odds of having OH. Conclusions: OH and frailty are prevalent in community dwelling elderly in Thiruvananthapuram district. Frailty may be a risk factor for OH in the first minute. The number of co-morbidities may be an independent risk factor for OH. Hence, elderly people with comorbidities and cognitive impairment may be actively assessed for OH to prevent falls and associated injuries.
ABSTRACT
Introduction: For the diagnosis of diabetes mellitus, various tests are available such as FBS (Fasting blood sugar), PPBS ( Post Prandial Blood Sugar), Oral Glucose Tolerance Test, Random Plasma Glucose Test, HBA1c, etc, of which HBA1c is considered to be the most standard test.1,2 As diabetes mellitus can be asymptomatic initially, it can lead to important complications such as neuropathy, nephropathy, retinopathy, cardiovascular diseases, etc if not detected early.3 Postural blood pressure measurement which diagnoses orthostatic hypotension is a cheap, easy and useful tool to predict HBA1c level even in asymptomatic diabetic patients. Methods: This is a randomized cross-sectional study of 100 diabetic patients attending Medicine OPD or admitted in our tertiary care hospital of South Gujarat. Pretested proforma was used to collect data after taking informed consent. Investigations including blood pressure measured with a standard Sphygmomanometer at the end of 3 min after standing and HBA1c as mentioned in the proforma was carried out. Final analysis has been done with Open EPI and SPSS software. Results: 33% of patients of our study population were found with abnormal orthostatic hypotension. Our data shows orthostatic hypotension is directly associated with high HbA1c, longer duration of DM, and higher value of BMI. No correlation was found between age and gender. Conclusion: Among diabetic patients, high HbA1c, prolong duration of DM and high BMI were associated with abnormal orthostatic hypotension, which can be alarming sign of complications of diabetes mellitus.
ABSTRACT
Orthostatic hypotension (OH) is defined as a drop of >20 mm Hg of systolic or >10 mm Hg of diastolic blood pressure (BP) within 3 min of standing from lying position. It is a common geriatric syndrome caused by impaired orthostatic response of BP. Its clinical manifestation can range from dizziness to syncope. It is a common cause of recurrent falls and fracture in older adults. Its etiology ranges from neurological causes such as Parkinson and diabetes to hypovolemia. Drugs, especially cardiovascular drugs are also frequently identified as the cause of OH. The management of OH is primarily nonpharmacological including medication review, dietary, and lifestyle modifications. However, in partially responsive or resistant cases, medications such as fludrocortisone, midodrine, droxidopa, etc., are also used.
ABSTRACT
SUMMARY OBJECTIVE: The objective of this study was to analyze the association between orthostatic changes in blood pressure and mortality in elderly cardiopath patients. METHODS: A cohort of 455 elderly cardiopath patients, monitored at a referral outpatient cardiology clinic in Pernambuco, Brazil, from October 2015 to July 2018. The exposure groups were formed according to their orthostatic changes in blood pressure following the requirements of the Brazilian Guidelines for Hypertension. RESULTS: Orthostatic hypotension was present in 46 patients (10.1%), 91 had orthostatic hypertension (20%), and 318 had no orthostatic alterations (69.9%). There were 52 deaths during follow-up. The results demonstrated that there was no statistically significant association between orthostatic hypotension and overall mortality (HR 1.30; 95%CI 0.53-3.14; p=0.567) nor between orthostatic hypertension and overall mortality (HR 0.95; 95%CI 0.65-1.39; p=0.34). Survival in relation to the exposure groups presented no statistically significant difference (p=0.504). CONCLUSION: There was a low frequency of orthostatic hypotension and a mild high frequency of orthostatic hypertension when compared with previous studies, and no association was observed with overall mortality or with the survival time of elderly patients with heart disease.

Immunoglobulin light chain amyloidosis (AL) is characterized by the extracellular tissue deposition of insoluble fibrils as a result of protein misfolding. These tissue deposits may be responsible for progressive failure in several organs. Among them, neuropathy may be presented as the first manifestation. The patient reported here presented initially with autonomic nervous system impairment, mainly characterized by severe refractory orthostatic hypotension, which became progressively invalidating, forcing the patient to bed. Moreover, since the systemic involvement of the disease, the patient also presented with diarrhea, peripheral polyneuropathy, and kidney dysfunction. Eventually, the massive myocardial depression and infiltration led to a fatal outcome due to ventricular fibrillation. Examination revealed M protein in serum and urine protein electrophoresis. Rectal mucosa and skin biopsy confirmed amyloidosis, and bone marrow biopsy showed cellular infiltration was over 35% with 23% immature plasma cells. The patient was confirmed as AL with multiple myeloma.
ABSTRACT
Objective:To understand the predictive effect of orthostatic hypotension on frailty in nursing homes, and the effect of frailty on heart rate and blood pressure in supine positionand orthostatic position.Methods:A total of 214 elderly cases in three nursing homes (the Golden Years of Jinjialing Retirement Life Center, Hangzhou Boyang Pension Service Co., Ltd, Hangzhou Langhe International Medical Care Center) were interviewed by the general information questionnaire, the Frail Scale and Barthel Index. Systolic blood pressure, diastolic blood pressure, and heart rate were measured by electronic sphygmomanometer in supine position and orthostatic position of 1 and 3 minutes.Results:The incidence of frailty combined with orthostatic hypotension was 26.64%(57/214) in the elderly in nursing homes. The incidence of orthostatic hypotension in the robust elderly, pre-frailty and frailty gradually increased, 14.29%(5/35), 20.00%(12/60), 47.90%(57/119). The differences of heart rate and systolic blood pressure in supine position between the elderly with and without frailty were significant ( t=2.16, 3.25, P<0.05), the differences of systolic pressure difference in orthostatic position of 1 and 3 minutes between the elderly with and without frailty were significant ( H=3.16, 4.08, P<0.01). There was significant difference in systolic pressure between the prefrail elderly and the elderly without frailty in lying position ( t=2.02, P<0.05). The differences of systolic and diastolic pressure differences in orthostatic position of 3 minutes between the frail elderly and pre-frail elderly were significant ( H=3.13,2.44, P<0.05). Ordered Logistic regression analysis showed that orthostatic hypotension was a risk factor for frailty ( OR=2.425, 95% CI were 1.133-4.988, P<0.05). Conclusions:Elderly adults with orthostatic hypotension in nursing homes have a higher prevalence of frailty. Frailty also impairs blood pressure regulation during postural changes. Nurses should attach importance to the assessment, education and intervention of frailty and orthostatic hypotension.
ABSTRACT
Ryokeijutsukanto is an herbal medicinal product that is often used for dizziness when standing up, that is, orthostatic dysregulation. This time, we encountered 2 patients with orthostatic dysregulation successfully treated with ryokeijutsukanto, and objectively evaluated the therapeutic effect of ryokeijutsukanto by using Visual Analog Scale (VAS), Vertigo Symptom Scale-short form (VSS-sf) Japanese version and Dizziness Handicap Inventory (DHI) Japanese version. Case 1 is a 17-year-old woman. Dizziness when standing up appeared from 2 month ago. Before treatment, VAS scored 71/100, VSS-sf scored 7 points, and DHI scored 42 points. After 4 weeks of administration of Ryokeijutsukanto, VAS improved to 22/100, VSS-sf improved to 6 points, and DHI improved to 26 points. Case 2 is a 38-year-old woman. Dizziness when standing up appeared from 3 month ago. Before treatment, VAS scored 48/100, VSS-sf scored 18 points, and DHI scored 32 points. After 4 weeks of administration of Ryokeijutsukanto, VAS improved to 9/100, VSS-sf improved to 3 points, and DHI improved to 20 points. In both cases, all the evaluation scales showed sharp improvement after 4 weeks, indicating that ryokeijutsukanto was certainly effective.
ABSTRACT
La acrocianosis desencadenada por la bipedestación como signo principal de la taquicardia postural ortostática (POTS, por su sigla en inglés) es poco conocida, aunque bien descrita en la bibliografía especializada. Se describen dos casos clínicos de adolescentes que consultaron en el Servicio de Urgencias por acrocianosis e intolerancia al ortostatismo. El primer paciente, de 13 años, presentó un aumento de la frecuencia cardíaca de 40 latidos por minuto (lpm) al pasar del decúbito a la bipedestación. El segundo, de 14 años, presentó un aumento de la frecuencia cardíaca hasta 125 lpm al incorporarse. En ambos, la tensión arterial y los estudios complementarios fueron normales. El POTS se define en la edad pediátrica como una intolerancia al ortostatismo que se acompaña de aumento de la frecuencia cardíaca excesiva sin hipotensión arterial. Conocer la acrocianosis como primer signo de presentación es de utilidad para el diagnóstico de esta enfermedad y para evitar estudios complementarios innecesarios.
Acrocyanosis triggered by standing position as the main sign of postural orthostatic tachycardia (POTS) is little known but well described in scientific literature. In pediatric age, POTS is defined as orthostatic intolerance that is accompanied by an excessive increase in heart rate without arterial hypotension. We present two clinical reports of teenagers who were admitted in the Emergency Department with acrocyanosis and orthostatic intolerance. The first patient was 13-year-old and had an increase in heart rate of 40 bpm when moving from a reclining to a standing position. The second patient was 14-year-old and showed an increasing in heart rate up to 125 bpm after upright position. In both patients' blood pressure was normal and all investigations were negative. They were finally diagnosed with postural orthostatic tachycardia. Recognizing acrocyanosis as first sign of this disease is useful for diagnosis and can help to avoid unnecessary testing.
