Enfermagem na atenção primária em saúde no screening de adolescentes com excesso de peso

One of the Primary Health Care strategies for adolescent health is the growth and development follow-up and the early detection of overweight adolescents. Even though the School Health Program in Brazil proposes to evaluate the nutritional state of the school population in the corresponding community health units, not all cities have adhered to the Program and many nurses do not recognize overweight as a problem in their territory. The objective of the study was to identify the nurse´s participation in the screening of overweight adolescent students in their work territory. Cross sectional study conducted in eight state supported schools of the municipality of Natal/RN and in four Primary Health Units. The total student population was 27.277. A stratified sample was statistically calculated based on the student population of the four city geographical zones: 112 North , 74 West; 108 East; and 78 South, totalizing 372 adolescents. The students were selected by a probability process where eight schools were first selected, two per district, until the number per subsample in each district was reached. Four primary health nurses, responsible for the health units were included. Two instruments were used for data collection, a screening questionnaire and a semi-structured interview form for questioning of the nurses. The content of both instruments was validated. Anthropometric and health data were collected from the students and analyzed with descriptive and analytical statistics. Interview data were transcribed and submitted to content analysis. The nursing diagnosis of overweight was identified in 50 (13,5%) of the adolescents and its association with consumption of foods that have cardiovascular risk (canned foods, pasta and fried food). An association of the nursing diagnosis was identified with family history (diabetes, hypertension, obesity, and kidney disease). The nurses judged that care of overweight adolescents was important but noted difficulties because of the absence of this population in the health units, because of their work overload, and the lack of school articulation. The nurses do not have impacting actions with this population and delegate the responsibility to other professionals. It is concluded that overweight is a nutritional problem relevant to the adolescent school population in Natal/RN, with a 13,5% prevalence and that it is related to food consumption with cardiovascular risk and family health history. The nurses consider overweight as an important public health problem but do not envision ways to maintain linkage with adolescents and with the school to promote the needed care

Tradução, adaptação cultural e avaliação psicométrica da prova cognitiva de leganés em uma população idosa brasileira com baixo nível de escolaridade

Introdução: The scales of cognitive screening are important tools for early detection of dementia, creating the possibility of developing measures to slow this process and assist in the management of the disease. Objective: To validate the Leganés Cognitive Test (Prueba Cognitive de Leganés) (PCL) for cognitive screening in low educated elderly Brazilians. Methods: The study sample was composed of 59 elderly residents from the city of Santa Cruz, Brazil with low schooling levels. Reliability was analyzed with a 2-day interval between assessments, and concurrent validity was assessed using the Mini Mental State Examination (MMSE). Results: According to the PCL, the prevalence of dementia was 11.8%. The scale items showed a moderate to strong correlation between domains (p <0.01), and inter-rater reliability exhibited ICC = 0.81, 95% CI (0.72-0.88). Factor analysis resulted in two factors: memory and orientation. Interscale agreement was considered poor (k = - 0.02), supporting the hypothesis of an educational impact on final MMSE scores. Conclusion: The results suggest that PCL has acceptable levels of reliability for use in low educated elderly Brazilians

Atenção precoce do câncer de mama :um olhar sobre o cotidiano institucional de uma unidade de saúde de Natal

Breast cancer has been considered a grave global public health problem due to its increase in incidence, in women s mortality and in the amount of financial resources spent on the therapeutic interventions used in the treatment of this neoplasia. However, this scenario presents some variations. In developing countries, the incidence of breast cancer is increasing but, on the other hand, the mortality is declining among patients because of public health actions toward early diagnostic that also result in cure of patients and decreasing levels of physical and psychosocial stress. In Brazil, we face of both the increasing number of breast cancer incidence and number of mortalities. Almost always the reason for that is a delayed detection that will provide a late diagnostic. The early detection of breast cancer has been studied in several researches. Some of them are concerned with women s experiences. Despite that, there is a lack of researches on dynamic comprehension of early attention to breast cancer from the health professionals points of view. The present research was carried out at the Unidade Mista de Felipe Camarão (UMFC) and it was conducted with 11 professionals who work in the Family Health Program (PSF). The aim was to understand how early diagnostic and attention to breast cancer is being planned, discussed and accomplished by health professionals in their day-to-day actions. Semi-structure interviews were held individually with each professional, in a way that they could feel free to express their ideas about several issues. All the information from these interviews was analyzed and discussed using an Institutional Ethnographic approach. It was observed that the actions of health professionals working with early detection of breast cancer does not take place in a vacuum; they occur within institutional, relational and social ways. This interdependence influences their actions and points of view on the theme

Miocardiopatia diabética

A miocardiopatia diabética é uma doença do músculo cardíaco causada pelo diabetes mellitus e não relacionada às patologias vascular e valvular ou à hipertensão arterial sistêmica. Observações experimentais e clínicas têm demonstrado hipertrofia, necrose, apoptose e aumento do tecido intersticial miocárdico. Acredita-se que a miocardiopatia diabética seja decorrente de anormalidades metabólicas como hiperlipidemia, hiperinsulinemia e hiperglicemia, e de alterações do metabolismo cardíaco. Tais alterações podem causar aumento do estresse oxidativo, fibrose intersticial, perda celular e comprometimento do trânsito intracelular de íons e da homeostase do cálcio. Clinicamente, é possível a detecção de disfunção diastólica assintomática na fase inicial. No momento em que surgem os sinais e sintomas de insuficiência cardíaca, observamos disfunção diastólica isolada, sendo que o comprometimento da função sistólica, habitualmente, é tardio. O tratamento da miocardiopatia diabética com insuficiência cardíaca não difere das miocardiopatias de outras etiologias e deve seguir as diretrizes de acordo com o comprometimento da função ventricular, se diastólica isolada ou diastólica e sistólica.

A university extension course in leprosy: telemedicine in the Amazon for primary healthcare

There is a high prevalence of leprosy in the Amazon region of Brazil. We have developed a distance education course in leprosy for training staff of the Family Health Teams (FHTs). The course was made available through a web portal. Tele-educational resources were mediated by professors and coordinators, and included the use of theoretical content available through the web, discussion lists, Internet chat, activity diaries, 3-D video animations (Virtual Human on Leprosy), classes in video streaming and case simulation. Sixty-five FHT staff members were enrolled. All of them completed the course and 47 participants received a certificate at the end of the course. At the end of the course, 48 course-evaluation questionnaires were answered. A total of 47 participants (98%) considered the course as excellent. The results demonstrate the feasibility of an interactive, tele-education model as an educational resource for staff in isolated regions. Improvements in diagnostic skills should increase diagnostic suspicion of leprosy and may contribute to early detection.

Associação entre acrocórdons e resistência à insulina

FUNDAMENTOS: Acrocórdons são lesões dermatológicas comuns na população e estão associados ao diabetes mellitus, à obesidade, à resistência insulínica e à aterosclerose. A identificação precoce de pacientes com resistência insulínica pode ter papel preventivo primário. OBJETIVO: Avaliar a associação entre presença de acrocórdons cervicais ou axilares e resistência insulínica. MÉTODOS: Estudo transversal com pacientes dermatológicos adultos atendidos em hospital universitário. Casos foram definidos como portadores de mais de cinco acrocórdons cervicais e/ou axilares. A resistência insulínica foi estimada pelo índice HOMA-IR. Resultados foram ajustados pelas demais covariáveis de risco para resistência insulínica conhecidos, a partir de regressão logística múltipla. RESULTADOS: Avaliaram-se 98 casos e 103 controles, que não diferiram entre si quanto à idade ou ao gênero. Acrocórdons se associaram diretamente aos valores de HOMA-IR (Odds Ratio = 1,4), hipertrigliceridemia e índice de massa corpórea, independentemente do ajuste por diabetes mellitus, idade, fototipo, gênero, história de diabetes mellitus familiar e relação cintura/quadril. Níveis qualitativamente elevados de HOMA-IR (> 3,8) também evidenciaram associação significativa (Índice de probabilidade = 7,5). CONCLUSÕES: Presença de múltiplos acrocórdons se associou à resistência insulínica, independentemente dos demais fatores de risco.

Alternative Treatment Modalities for Immature Intruded Permanent Incisors: Report of 2 Cases

Intrusion of permanent teeth is one of the most severe types of traumatic injuries. Different treatment strategies have been proposed, and the best approach for each case depends on the stage of root development, severity of the intrusive luxation, presence of alveolar fracture and number of intruded teeth. The purpose of this paper is to describe the treatment management of 2 cases of severely intruded immature permanent maxillary central incisors in 71/2- and 8-year-old children. In case 1, the traumatized tooth was treated by surgical repositioning, while in case 2 watchful waiting for spontaneous re-eruption was the treatment of choice. Treatment strategies were successful in both cases, as demonstrated by the continuation of root development, maintenance of pulp vitality, and absence of signs of per/apical pathosis during the follow-up period. Regardless of the treatment strategy, traumatically intruded teeth should undergo periodical clinical and radiographic surveillance on a long-term basis to allow early detection of possible complications.

The Efficacy of Laser Fluorescence to Detect in Vitro Demineralization and Remineralization of Smooth Enamel Surfaces

Objective: The purpose of this study was to evaluate the efficacy of the laser fluorescence (LF) device in detecting in vitro demineralization and remineralization of smooth surface caries-like lesions. Background Data: The early detection of smooth surface caries-like lesions is important to provide proper management of carious lesions, and allows monitoring of them over time. Also, some authors suggest that LF could be useful in monitoring the caries pathological process. Materials and Methods: Seventy-eight blocks of bovine teeth were obtained, and then submitted to artificial caries lesion induction and to a pH-cycling process. Superficial microhardness (SMH) and laser fluorescence analysis were performed at baseline, after induction of caries-like lesions, and after the pH-cycling regimen to promote remineralization. Results: Friedman's and multiple comparison tests were performed for all variables. SMH analysis showed significant differences (p < 0.05) between baseline (286.77 +/- 1.49 Vickers hardness number [VHN] units), before (38.48 +/- 0.85 VHN), and after remineralization (131.93 +/- 2.63 VHN). Baseline values for LF were extremely low (2.71 +/- 0.05), and a statistically significant difference was observed only after remineralization (3.61 +/- 0.08), as demonstrated by the increase in LF values. Conclusion: The LF device did not show efficacy for monitoring in vitro demineralization and remineralization of smooth enamel surfaces.

Oral bisphosphonate-related osteonecrosis of the jaws in rheumatoid arthritis patients: a critical discussion and two case reports

Background: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a clinical condition characterized by the presence of exposed bone in the maxillofacial region. Its pathogenesis is still undetermined, but may be associated with risk factors such as rheumatoid arthritis (RA). The aim of this paper is to report two unpublished cases of BRONJ in patients with RA and to conduct a literature review of similar clinical cases with a view to describe the main issues concerning these patients, including demographic characteristics and therapeutic approaches applied.Methods: Two case reports of BRONJ involving RA patients were discussedResults: Both patients were aging female taking alendronate for more than 3 years. Lesions were detected in stage II in posterior mandible with no clear trigger agent. The treatment applied consisted of antibiotics, oral rinses with chlorhexidine, drug discontinuation and surgical procedures. Complete healing of the lesions was achieved.Conclusions: This paper brings to light the necessity for rheumatologists to be aware of the potential risk to their patients of developing BRONJ and to work together with dentists for the prevention and early detection of the lesions. Although some features seem to link RA with oral BRONJ and act as synergistic effects, more studies should be developed to support the scientific bases for this hypothesis.

Diagnóstico de hemoglobinopatias em recém-nascidos do Hospital de Base de São José do Rio Preto-SP

The neonatal period is considered the most effective for the screening of hemoglobinopathies. This allows prophylaxis and prevention, improving the patient's survival and guidance of parents and heterozygote carriers. The present work aims at the early detection of abnormal hemoglobins, the establishment of standard analysis and to examine the viability of the prevention program. Blood samples were collected by heel stick and from blood cord of children born in the Hospital de Base São José do Rio Preto, from April 1998 to November 1999. Electrophoresis and cytological, biochemical, cromatographic analyses were made for abnormal hemoglobin characterization. A total of 1,478 neonatal blood samples were analyzed in which 14.62% presented with hemoglobins alterations: 3.32% had Hb S; 0.61% had Hb C; 7.44% were suggestive of alpha thalassemia; 1.55% were suggestive of beta thalassemia, and 1.70% had alpha/beta thalassemia interactions. The samples collected from the blood cord showed better results in all analyses while the blood samples collected by heel stick on filter paper, were applicable to only specific methodologies. The routine laboratory methods allowed identification of the thalassemic and variant forms, and isoelectric focusing presented sensitivity only for variant identification in this age range. The suspected cases were reassessed after six months, which permitted genetic counseling of their family members and clinic attendance. A multidisciplinary approach in programs of this kind is fundamental for its success.

Validade da citologia cervicovaginal na detecção de lesões pré-neoplásicas e neoplásicas de colo de útero

Introdução: O exame colpocitológico ou teste de Papanicolaou permite o diagnóstico precoce do câncer de colo do útero. O êxito no rastreamento desta doença dependerá, além de outros fatores, da acuidade diagnóstica do exame colpocitológico. Objetivos: Avaliar a acurácia diagnóstica da citologia cervicovaginal na detecção de lesões cervicais através da comparação citoistopatológica. Material e métodos: Avaliou-se o grau de concordância entre os exames citológico e histopatológico de 373 pacientes atendidas em um hospital universitário no período de 1990 a 1997 e foram calculados os indicadores: sensibilidade, especificidade, valores preditivos positivos e negativos e as taxas de falsos positivos e falsos negativos do exame. Resultados: A taxa bruta de concordância citoistopatológica foi de 65,1%. A sensibilidade do exame foi alta (96,0%), no entanto sua especificidade foi baixa (51,5%), significando a inclusão de muitos resultados falsos positivos. A taxa de falsos positivos foi de 48,4%, enquanto a de falsos negativos foi de 4%. Discussão: Apesar de a sensibilidade do teste ser alta, sua especificidade é baixa, significando que muitas mulheres seriam falsamente diagnosticadas como doentes, levando a um número elevado de resultados falsos positivos e custos desnecessários, além do potencial caráter iatrogênico que esta ação poderia assumir. No entanto, um exame altamente sensível é o teste de escolha para programas de rastreamento de câncer cervical na população feminina. Conclusões: Para garantir a acuidade diagnóstica do teste de Papanicolaou são essenciais atividades de controle de qualidade nos laboratórios, tanto do procedimento colpocitológico quanto do histopatológico, permitindo, assim, o êxito na detecção precoce e no tratamento das lesões cervicais.

Salt stress change chlorophyll fluorescence in mango

Este trabalho teve como objetivo avaliar o efeito do estresse salino sobre a eficiência fotoquímica do fotossistema II (PSII) nas cultivares de manga 'Haden', 'Palmer', 'Tommy Atkins' e 'Ubá' enxertadas sobre o porta-enxerto 'Imbu'. Foi utilizada solução nutritiva de Hoagland modificada contendo 0; 15; 30e 45 mmol L-1 NaCl. Aos 97 dias após a exposição ao estresse salino, foram avaliados os parâmetros da fluorescência da clorofila (F0, Fm, Fv, F0/Fm, Fv/Fm, Fv'/Fm', ΦPSII = [(Fm'-Fs)/(Fm')], D = (1- Fv'/Fm') e ETR = (ΦPSII×PPF×0,84×0,5). Aos 100 dias, foram avaliados a emissão foliar, a área média de folhas (cm²), o índice de toxidez nas folhas e o índice de abscisão foliar. em todas as cultivares, em graus diferenciados, ocorreram decréscimo na eficiência fotoquímica do fotossistema II, na emissão de folhas, e aumento nos índices de toxidez e abscisão foliar, intensificados nas concentrações a partir de 15 mmol L-1 NaCl. As plantas cultivadas em 45 mmol L-1 NaCl apresentaram decréscimos na razão Fv/Fm de 27,9; 18,7; 20,5 e 27,4%, incremento no índice de toxidez foliar de 33,0; 67,5; 41,6 e 80,8% e no índice de abscisão foliar de 71,8; 29,2; 32,5 e 67,9% para as cultivares 'Haden', 'Palmer', 'Tommy Atkins' e 'Uba', respectivamente. Os decréscimos na razão Fv/Fm foram acompanhados de redução na emissão de folhas e aumento no índice de toxidez foliar, mostrando, portanto, o potencial da fluorescência da clorofila na detecção precoce de estresse salino em mangueira.

Cistoadenoma mucinoso do apêndice: relato de caso

O cistoadenoma mucinoso do apêndice ceca l, um tipo de mucocele do apêndice, é uma neoplasia benigna caracterizada pela metaplasia focal ou difusa do epitélio superficial da mucosa, associada à dilatação do apêndice e produção de muco para a luz apendicular. No presente estudo os autores relatam um caso de cistoadenoma mucinoso do apêndice observado em uma mulher de 65 anos de idade, com dor e massa palpável no quadrante inferior direito do abdome, cujo quadro teve início há 1 ano. O diagnóstico de cistoadenoma do apêndice foi suspeitado através da ultrassonografia e tomografia computadorizada do abdome, e confirmado pelo exame histopatológico. A paciente também apresentava cálculos na vesícula biliar e um cisto renal à direita. A laparotomia foi indicada sendo realizada a apendicectomia, a colecistectomia e a exérese do cisto renal. Na presente discussão esperamos contribuir para o diagnóstico precoce dessa doença e a melhor compreensão de sua classificação e patogenia.
