Síndrome de Cogan: achados oculares em um caso da forma atípica

A síndrome de Cogan é entidade multissistêmica rara caracterizada por ceratite intersticial associada à disfunção áudio-vestibular e possível surdez irreversível classificada em duas formas clínicas: típica e atípica. Há discordância na literatura quanto à presença de acometimento corneano na forma atípica. Uma paciente de 32 anos queixando-se de hiperemia e dor ocular, fotofobia e baixa da acuidade visual no olho direito, associada à perda súbita de audição à esquerda, vômitos, diarréia, oligúria, dor na orofaringe e febre. História prévia de semelhante acometimento do olho esquerdo e audição direita. Havia intensa hiperemia conjuntival, esclerite nodular, episclerite e infiltrados circulares no estroma corneano. A paciente recebeu pulsoterapia com metilprednisolona e ciclofosfamida. Evoluiu com grande melhora ocular, porém com resposta auditiva pobre. O caso reportado pode constituir forma típica da síndrome de Cogan (de acordo com autores que defendem o nãoacometimento corneano na forma atípica) com alguns achados característicos da forma atípica ou um caso da forma atípica da síndrome de Cogan (para aqueles que defendem o acometimento corneano na forma atípica). O diagnóstico diferencial também é discutido

Síndrome de ovários policísticos: enfoque psicossocial

A síndrome dos ovários policísticos (SOP) é um distúrbio endócrino-ginecológico que se caracteriza, principalmente, por anovulação crónica e hiperandrogenismo, afetando entre 5 a 10% das mulheres em idade reprodutiva. As principais manifestações da SOP incluem os seguintes sintomas: irregularidade menstrual, hirsutismo, infertilidade, acne, alopecia androgenética, obesidade e acantose nigricans. Esses sintomas apresentam- se de forma bastante heterogênea, havendo diferenças marcantes na sua prevalência e intensidade entre diferentes grupos de mulheres que apresentam SOP. Apesar da condição biológica, a SOP não é apenas um problema físico, mas também psicossocial, interferindo e comprometendo a qualidade de vida das mulheres que a apresentam. A partir de uma revisão da literatura, este estudo discute os aspectos psicossociais de mulheres com SOP, destacando o impacto dos sintomas na qualidade de vida relacionada com a saúde. Considerando que cada mulher responde de forma singular aos sintomas que apresentam, destaca-se a importância de incorporar a perspectiva individual da mulher com SOP ao seu contexto social. Nesse sentido, são discutidos achados de pesquisas utilizando abordagens metodológicas quantitativas e qualitativas, numa tentativa de melhor compreender a experiência das mulheres diante da SOP. Os sintomas da SOP podem estar associados com a ocorrência de ansiedade, disfunções sexuais e sentimentos de inadequação ao papel feminino, como também podem desencadear sintomas depressivos e isolamento social, com comprometimento significativo da qualidade de vida. Os autores destacam a importância do atendimento multidisciplinar para as mulheres com SOP, considerando essa condição como importante problema psicossocial. A atenção aos aspectos psicossociais da SOP tem aumentado nos últimos anos, no entanto, a produção científica relacionada ainda é escassa

Síndrome metabólica em mulheres com síndrome dos ovários policísticos: prevalência em cidade da região nordeste do Brasil

Resumo

BURNOUT: analisando a síndrome do ramo das indústrias alimentícias do Rio Grande do Norte

This paper aims to verify the Burnout´s possibilities of incidence, finding the creating dimensions and comparing with the socio-demographics characteristics of the researched professionals. This quantitative-descriptive search has a population of 197 workers of 23 nourishing companies in Rio Grande do Norte. This population is predominantly male, younger than 28 years old, single, relatively instructed (57,07% with complete high school) and having just started their current job since 79% of the interviewees are in the company less than six years. The AUDITORIA DO SISTEMA HUMANO (ASH) model, utilized for investigation and developed for the Spaniards Quijano and Navarro in 1999, has several dimensions about human resources management and the organizational effectiveness, but only makes part of the research in 19 questions Burnout referring. It was used factorial analyses with extraction method, varimax rotation and Kaiser normalization with the intuition to define the creating dimensions of the syndrome, they were evaluated with Cronbach Alpha coefficient after extraction. The dimensions found through the factorial analyses were: emotional exhaustion, physical exhaustion and vitality. The accumulated explanation value reached 65,30% of total variation. The data socio-demographics don t justify the syndrome appearance, because the T test and ANOVA showed irrelevant values. It has been also observed that the founded dimensions were different of the Maslach sociopsychological perspective (emotional exhaustion, depersonalization and low professional realization) allowing comparison with others researches and the possibility to develop new ones with workers from different assistance areas. These new researches are important, since the syndrome refers to chronic labor stress consequences and any professional is favorable to Burnout, harmful to the company as to the collaborators

Síndrome de burnout e autoeficácia: um estudo com profissionais de enfermagem de hospitais privados de Natal/rn

This research verifies the influence of the self-efficacy level on burnout syndrome incidence in relation to nursing professionals from private hospitals located in the Municipality of Natal, State of Rio Grande do Norte. The nature of the research was descriptive, and the used data analysis method was quantitative which was developed through SPSS computational package, version 17.0. The used instrument for the investigation was Maslach-Burnout Inventory (MBI), and the General Perceived Self-efficacy Scale (GPSES) was applied to a sample formed from 230 nursing professionals. The statistic techniques to data analysis were: frequency analysis; factor analysis; Cronbach.s alpha; Kaiser-Meyer-Olkin test (KMO); Bartlett efericity test; percentual analysis; Spearman rank correlation analysis; and simple regression. The achieved factors from factor analysis of MBI were the same, taking into account the dimensions which Maslach initially suggested to the instrument (emotional exhaustion, lack of personal realization, and depersonalization). However, one highlights that the low internal consistence of the depersonalization dimension can occur from people.s difficulty (caused by cultural aspects) of assuming this attitude in their work environment. Through GSE, it was achieved a factor which confirmed the unidimensionality showed by the author of the instrument. In relation to the syndrome incidence, it was verified that about 50% of the researched sample presented burnout syndrome evidence. Referring to self-efficacy level, about 65% of the researched sample presented low level of self-efficacy, what can be explained by the work characteristics of these professionals. In relation to the self-efficacy influence on the Burnout syndrome, it was verified that self-efficacy can be one of the aspects which influences occupational stress chronification (burnout), mainly to the personal realization dimension. Therefore, the researched hospital organizations need reflect about their attitudes in respect to their professionals, since the numbers showed a dangerous tendency regarding a predisposition to burnout syndrome of their staff, what implies not only a significant amount of individuals who can present high levels of emotional exhaustion, lack of personal realization, and depersonalization, but also the fact that this group presents low level of self-efficacy

Síndrome de Burnout : um estudo com guias de turismo regional em Natal-RN

Burnout is a psychological syndrome triggered in response to continuous exposure to interpersonal stressors. It is considered a multifactorial construct, which is commonly characterized by three dimensions: emotional exhaustion, dehumanization, and lack of personal accomplishment.This study aimed to verify if the three characteristics of burnout (exhaustion, lack of dehumanization and personal accomplishment) are present in people working as guides Tourism in Natal - RN. It is a descriptive and quantitative study. 109 subjects were surveyed. Data collection was done through the use of questionnaires, the instrument used was the characterization of the Burnout Scale (ECB) created and validated in Brazil by Trocoli and Tamayo (2000). In order to analyze data we used descriptive statistics, analysis of core measures, exploratory and confirmatory factor analysis, reliability analysis, cluster analysis, multiple discriminant and Spearman correlation. Factor analysis identified four factors that explain 58.3% of the total variance. Those factors were named exhaustion, deception, avoidance, and dehumanization. The reliability of the instrument, as measured by Cronbach's Alpha was 0.918, which is considered excellent reliability. The 109 subjects were grouped into three cluster, which had the deception, avoidance, and dehumanization as discriminant. It is possible to conclude that the characteristics of burnout syndrome are present in the studied population where 19 people are on the high level of burnout, moderate in 32 and 56 in the light. The correlations between socio-demographic variables studied and the dimensions of burnout, were few and weak. The variable leave for health reasons in the study appeared to be related to feelings of exhaustion and avoidance behavior appeared related to younger individuals and who work only in the activity of Receptive Tourism Guide. Verification of the incidence of burnout in individuals surveyed suggest the need to adopt intervention strategies are individual, organizational and / or combined

Avaliação da efetividade de estratégias não farmacológicas para o alívio da dor de parturientes na fase ativa do período de dilatação no trabalho de parto

This study was aim to evaluate the effectiveness of strategies non pharmacological for the relief of the intensity of the parturient pain in the phase activates of the dilation period in the labor. Is a clinic rehearse of the type therapeutic intervention before and after" with a quantitative approach, accomplished in the Humanized Unit of Childbirth of the Maternity Januário Cicco School of the Federal University of Rio Grande do Norte, in Natal/RN, whit 130 parturient, being 30 in the pre-test of the strategies and 100 in the application of the strategies non pharmacological combined (breathing exercises, muscular relaxation and lombossacral massage) and isolated (shower bath in a normal temperature). We used the visual analogical scale to evaluate the intensity of the pain of the study parturient before and after" to the application of the strategies in the phases of acceleration, maximum inclination and desaceleration in the phase activates of dilation period in the labor. The principal results showed that the majority of the study parturient was between 20 to 30 years old (60%); with incomplete fundamental teaching (85%); family income until 2 minimum wages (74%); 78% had a companion and these, 44% were the own husband. The oxytocin was administered in the parturient during the phase activates of the labor in 81% of the cases and only 15% these women didn´t reciev anything medication. We verified significant relief (ρ=0.000) of intensity of the pain of the study parturient after application of the strategies non pharmacological combined and isolated. We concluded that the strategies non pharmacological combined and isolated were effective in the relief of the pain of the study parturient in the phase activates de labor

Redução da morbi-mortalidade na síndrome de hellp completa com o uso de altas doses de dexametasona

Objective: To determine the clinical maternal and neonatal outcomes in HELLP syndrome patients treated with dexamethasone who either developed renal injury or renal insufficiency and to identify predictive values of urea and creatinine for the identification of subjects with HELLP syndrome at risk of developing renal insufficiency. Methods: Non-radomized intervention study of dexamethasone use in HELLP syndrome. A total of 62 patients were enrolled at Maternidade Escola Januário Cicco (MEJC). Patients received a total of 30 mg of dexamethasone IV, in three doses of 10 mg every 12 hours. A clinical and laboratory follow up were performed at 24, 48 and 72 hours. Patients were followed up to 6 months after delivery. Patients were grouped in accordance to renal function, i.e, normal and some type of renal lesion. Renal lesion was considered when creatinine was equal or greater than 1.3 mg/dl and diuresis less than 100 ml in 4 hours period and renal insufficiency was defined when dialysis was needed. Results: A total of 1230 patients with preeclampsia were admitted at MEJC. Of those 62 (5%) developed HELLP syndrome. There was no statistical difference in the groups with renal involvement or normal renal function with respect to the demographics, type of anesthesia used and delivery, and weight of the newborn. An improvement in the AST, ALT, LDH, haptoglobine, antithrombine, fibrinogenen and platelets was observed within 72 hours after dexamethosone use. There was a significant increase in the diuresis within the interval of 6 hours before the delivery and 24 hours after it. Of the 62 patients, 46 (74. 2%) had normal renal function and 16 (25.8%) evolved with renal lesion, with 5 (8.1%) needing dialysis. These 5 patients who received dialysis recovered the xi renal function. The delay in administering dexamethasone increased in 4.6% the risk of development of renal insufficiency. Patients with renal insufficiency had received significantly more blood products than subjects without renal lesion (p=0.03). Diuresis, leukocytes, uric acid, urea, creatinine were significantly different between the groups with normal renal function, renal lesion and renal insufficiency. The levels of creatinine 1.2mg/dl and uric acid 51mg/dl, at admission are predictive of subjects who will evolve with renal lesion (p<0.001). Maternal mortality was 3.2%. None of the subjects with renal insufficiency evolved with chronic renal disease. Conclusions: Dexamethasone in patients with HELLP syndrome seems to reduce significantly the hepatic microthrombosis and normalize hemostasis as seen by improvement of liver function. Renal injury can be considered, in HELLP syndrome, when creatinine levels are greater than 1.3 mg/dl and diuresis less than 100 ml/h in interval of 4 hours. The level of creatinine greater than 1.2 mg/dl and urea greater than 51mg/dl are predictive of subjects with HELLP syndrome who will develop renal injury. Patients who receive more red cell packs develop renal insufficiency. Finally, the delay in administering dexamethasone increases the risk of developing renal insufficiency

Talassoterapia para pacientes com fibromialgia: ensaio clínico radômico

Fibromyalgia (FM) is a chronic rheumatic syndrome characterized by diffuse muscle-skeletal pain, and aerobic exercises represent a fundamental portion in therapeutic approach. Objective of this study was to evaluate the effectiveness of aerobic exercises accomplished in the water of the sea (thalassotherapy) for women with FM and to compare with exercises accomplished in the swimming pool, involving a multidisciplinary team, composed by rheumatologists, physical therapists, students of physical therapy and students of physical education. Forty six (46) women with age between 18 and 60 years with FM were randomized in 2 groups: a swimming pool group (23 patients) and a sea group (23 patients). 80th groups trained a week with the same program of aerobic conditioning 3 times (60 minutes each) for 12 weeks. Ali the patients were evaluated, before and immediately after treatment, with Visual Analogical Scale (VAS) for pain and fatigue, number of tending points, Fibromyalgia Impact Ouestionnaire (FIO), Short Form 36 Health Survey (SF-36), Pittsburgh Sleep Ouality Index (PSOI) and Beck Oepression Inventory (BOI). For statistical analysis, it was used paired-t test for analysis intra-group and non-paired test for inter-groups analysis, significance levei of p <0,05. Four patients, of each group, didn't complete the training programo Groups were homogeneous and they were compared in initial evaluation, except for BOI (p <0,05). Both groups presented statistically significant improvement for ali appraised parameters in the post-treatment compared with initial evaluation, there were reduction of intensity of pain and fatigue, number of tending points, better functional capacity (FIO), life quality (SF-36), quality of sleep (PSQI) and depression indexes (BOI). However, in comparison among the groups, group of sea (thalassotherapy) presented better results for ali parameters, however with statistically significant difference just only for depression indexes (BOI). At the end, it was observed that accomplishment of aerobic exercises in sea water or swimming pool was effective as part of treatment for patients with FM. However, exercise programs with thalassotherapy seems to bring more benefits, mainly related to emotional aspects, could be a therapeutic option of low cost for patients with FM in our area

Repercussões psico-sociais da síndrome dos ovários policísticos: estudo quali-quantitativo

BACKGROUND: Polycystic ovary syndrame (PCOS) has been shown to cause a reduction in quality of life. Little is known on the psychosocial aspects associated with PCOS, especially on women s own experiences regarding the syndrome. Therefore, the aim of this study was to analyze the psychosocial impact of PCOS by measuring the health-related quality of life and exploring the women s own experiences of PCOS. METHODS: A two-phase model of combination of quantitative and qualitative research approaches was conducted, a crass-sectional survey to pravide quantitative data on the quality of life and a qualitative approach to understand the women s experience in relation to the PC OS sympt?ms. For the first phase, 109 women with PC OS and 104 healthy contrais were evaluated with the 36-item short-form health survey (SF-36). Additionally, semi-structured interviews (n=30) were conducted to facilitate in-depth exploration of PC OS women s experience. RESUL TS: PCOS patients showed significant reductions in almost ali SF-36 domains of quality of life when compared with healthy contrais (physical function 76.5:!:20.5 and 84.6:!:15.9, respectively; physical rale function 56.4:!:43.3 and 72.6:!:33.3; general health 55.2:!:21.0 and 62.5:!:17.2; vitality 49.6:!:21.3 and 55.3:!:21.3; social function 55.3:!:32.4 and 66.2:!:26.7; emotional rale function 34.2:!:39.7 and 52.9:!:38.2; mental health 50.6:!:22.8 and 59.2:!:20.2). Thematic analysis revealed reports of feeling abnormal , sadness, afraid and anxiety. These feelings were related to four symptoms commonly experienced by women with PCOS: excess hair grawth; irregular or absent menstruation, infertility and obesity. CONCLUSIONS: Polycystic ovary syndrame impacts women both physically and psychosocially. Owing to this, women with PCOS need not only medical treatment for. the reproductive, esthetic and metabolic repercussions, but also the care of a multidisciplinary team, since PCOS is not just a physical condition, but also an important psychosocial problem that affects various aspects of a woman s life

Anormalidades cardiovasculares e metabólicas em pacientes com a síndrome de Berardinelli - SEIP

A Síndrome de Berardinelli-Seip (SBS) ou Lipodistrofia Generalizada Congênita acomete freqüentemente o aparelho cardiovascular e também promove anormalidades metabólicas envolvendo os metabolismos glicídico e lipídico. O objetivo do nosso trabalho foi avaliar a prevalência das anormalidades cardiovasculares e metabólicas em portadores da SBS. Vinte e dois pacientes do estado do Rio Grande do Norte (Brasil), com diagnóstico da SBS, foram submetidos à avaliação clinica, eletrocardiograma de repouso, ecodopplercardiograma, radiografia de tórax, eletrocardiografia dinâmica de 24 horas, teste ergométrico e análise laboratorial. Os pacientes eram predominantemente adultos jovens (n=22) , sendo 14 do sexo feminino. O mais novo tinha 8 e o mais velho 44 anos(22,4±9,7 anos). A totalidade da amostra apresentou resistência à insulina, acanthosis nigricans e HDL-colesterol diminuído. A presença de esplenomegalia, hepatomegalia, diabetes mellitus tipo II e triglicérides elevados eram constantes. A síndrome metabólica foi caracterizada em 81,8% dos pacientes com predominância para sexo feminino e com um alto grau de consangüinidade paterna (86,4%). A hipertensão arterial sistêmica e pré-hipertensão foram encontradas em mais da metade dos pacientes (77.3%). O eletrocardiograma e a radiografia de tórax não foram úteis para identificar a presença de anormalidades cardíacas na SBS, em particular a presença de hipertrofia ventricular esquerda. Para identificar o acometimento cardiovascular foi indispensável o estudo ecodopplercardiografico. Este exame mostrou a presença de hipertrofia concêntrica do ventrículo esquerdo (50%), hipertrofia excêntrica do ventrículo esquerdo (4,5%) e geometria normal do ventrículo esquerdo (45,5%). Disfunção sistólica do ventrículo esquerdo foi encontrada em apenas um paciente (4,5%) e disfunção diastólica em nenhum. Elevada taxa de arritmia foi evidenciada no Holter, tais como, extra-sístoles ventriculares, extra-sístoles supraventriculares e taquicardia supraventricular sustentada. Incompetência cronotrópica (54,5%) foi observada no teste ergométrico. Anormalidades cardiovasculares e metabólicas foram encontradas em elevada prevalência em indivíduos jovens e assintomáticos com SBS. Esses achados xii apontam para a necessidade de acompanhamento cardiológico sistemático e de medidas preventivas nesse grupo de risco

Fatores preditivos da dor em pacientes submetidos à cirurgia cardíaca

A identificação de fatores que interferem na dor pós-operatória é útil para minimizar o sofrimento desnecessário e favorecer a uma intervenção analgésica adequada, evitando generalizações nas condutas terapêuticas. O propósito dessa investigação foi identificar os fatores preditivos da dor em pacientes submetidos à cirurgia cardíaca e a relação existente entre dor, analgesia e personalidade. Trata-se de um estudo prospectivo e analítico, aprovado pelo comitê de ética da UFRN (175/06), o qual proporcionou uma abordagem multidisciplinar ao envolver áreas distintas como: fisioterapia, psicologia, médica e enfermagem (interdisciplinaridade) na elucidação do objeto de estudo relacionado a fatores preditivos da dor. Para caracterização geral dos pacientes foi utilizada uma ficha de avaliação fisioterapêutica; a dor pós-operatória foi avaliada pela escala numérica de dor e questionário para dor McGill e o Inventário Millon de Estilos de Personalidade (MIPS) foi utilizado para identificar e avaliar as manifestações das características comportamentais e de personalidade. Foram acompanhados, do 1º ao 5º dia de pós-operatório (DPO), 160 pacientes submetidos à cirurgia cardíaca, 57,5% do sexo masculino, com idade média de 56,8±14,4 anos, sendo incluídos no estudo aqueles que se queixaram de dor no pós-operatório em pelo menos um dos dias de avaliação e assinaram termo de concentimento livre e esclarecido (TCLE). Os dados foram submetidos ao teste Qui-quadrado, regressão logística multivariada, teste de correlação de Spearman, teste t e ANOVA. Ao serem submetidos à análise de regressão foram encontrados seis fatores preditivos da dor: tempo cirúrgico > 3 horas, dreno mediastinal e lateral, tosse, vômitos, tempo de dreno > 24 horas e sexo feminino. Estes fatores apresentaram uma correlação positiva e significava com a intensidade dolorosa referida pelos pacientes na escala numérica de dor e os pacientes que apresentaram mais fatores preditivos da dor referiram mais dor. 23 Já em relação ao McGill não se obteve diferença significativa entre os pacientes com mais e menos fatores preditivos. Observou-se que foram administrados diferentes tipos de analgésicos, isolados ou associados, sendo estes: paracetamol, paracetamol associado à codeína, dipirona, tramadol, toradol e tilatil. A percepção dolorosa apresentou magnitudes variando de leve a moderada do 1º ao 5º DPO e ao ser relacionada com as características de personalidade, nos pacientes com menos dor, observou-se os fatores: preservação, individualismo, introversão e os com mais dor foram: proteção, extroversão, retraimento, discrepância, afetividade, acomodação, comunicabilidade e firmeza. Evidenciou-se que o comportamento doloroso pós-cirurgia cardíaca é multifatorial e que a determinação da existência de fatores preditivos da dor permite ao profissional da área de saúde fazer o uso adequado dos analgésicos, haja vista que o alívio da dor é responsabilidade de todos os profissionais da saúde. Os aspectos psicológicos enquanto características de personalidade podem influenciar padrões de comportamento como os observados.

Influência da dor na capacidade funcional de idosos institucionalizados

The aim of this study was to evaluate the pain influence regarding location, intensity and duration over functional capacity in institutionalized elderly (Fundacao Leur Brito). This is a descriptive exploratory study with a transversal design and quantitative approach. The population of the study was composed of 60 elderly, being 50% males with 60 years-old minimum age and 104 years-old maximum age, with mean age 77,6 (?}11,64) years-old. Data was collected by a structured query formulary divided in four parts: 1) Social, health and demographic characterization; 2) Pain related aspects (time and location); 3) Pain evaluation by numeric scale and 4) Functional capacity measured by Barthel Index. It was observed after evaluation by Squared-chi test (x2) statistical significant difference between pain presence and Barthel Index activities: bath (pvalue=0,015), dressing (p-value= 0,041), intimal hygiene transference (p-value=0,001), chair and bed transference (p-value=0,032), walking (p-value=0,010) and go upstairs (p-value=0,008). It was also observed statistical difference between total Barthel score (dependent/independent) and pain presence, p-value<0, 000. Through data obtained by this study, a multiprofessional approach is necessary to proper pain control and maintenance and/or regain of functional capacity, leading to an increase in life quality with more independence and autonomy to elderly

Prevalência e fatores associados da síndrome de Osgood-Schlatter em uma amostra populacional de adolescentes brasileiros

Osgood-Schlatter (O-S) syndrome, a pathology of the musculoskeletal system, exhibits high incidence in adolescence, a phase of accelerated bone growth. Detection of physiopathological mechanisms that may cause disorders and dysfunctions in bone growth must be taken into account when planning physical activities, in order to promote normal physiological growth patterns. The aim of this epidemiological investigation was to identify and analyze the relationships between sociodemographic, anthropometric and clinical aspects and O-S. A cross-sectional design was used, with a representative sample of 956 subjects: 474 (49.6%) males and 482 (50.4%) females. Age range varied between 12 and 15 years (mean = 13.7±1.04). We used a battery of tests, previously applied in a pilot study, which met the aims of the investigation. Descriptive statistics (frequency, mean and standard deviation) were used and the odds ratio was calculated from bivariate and multivariate logistic regression (p<0.05). A prevalence of 9.8% was found (n = 94 cases): 11% males and 8.3% females. Hierarchized multivariate analysis showed a significant association between regular physical activities (OR= 1.94; CI 95%, 1.22-3.10) and shortening of the rectus femoris muscle (OR= 7.15; CI 95%, 2.86-17.86). The results may serve as a basis for therapeutic and prophylactic measures, in addition to increasing our knowledge of this syndrome in Brazilian adolescents. This investigation used a multidisciplinary approach, involving elements of anatomy, nutrition, physical education and physical therapy to elucidate the object under study related to Osgood-Schlatter syndrome
