Fisioterapia respiratória em crianças com pneumonia: revisão sistemática

Introduction: Pneumonia is an inflammatory lung disease and it is the greatest cause of deaths in children younger than five years of age worldwide. Chest physiotherapy is widely used in the treatment of pneumonia because it can help to eliminate inflammatory exudates and tracheobronchial secretions, remove airway obstructions, reduce airway resistance, enhance gas exchange and reduce the work of breathing. Thus, chest physiotherapy may contribute to patient recovery as an adjuvant treatment even though its indication remains controversial. Objectives: To assess the effectiveness of chest physiotherapy in relation to time until clinical resolution in children (from birth up to 18 years old) of either gender with any type of pneumonia. Methods: We searched CENTRAL 2013, Issue 4; MEDLINE (1946 to May week 4, 2013); EMBASE (1974 to May 2013); CINAHL (1981 to May 2013); LILACS (1982 to May 2013); Web of Science (1950 to May 2013); and PEDro (1950 to May 2013). We consulted the ClinicalTrials.gov and the WHO ICTRP registers to identify planned, ongoing and unpublished trials. We consulted the reference lists of relevant articles found by the electronic searches for additional studies. We included randomised controlled trials (RCTs) that compared chest physiotherapy of any type with no chest physiotherapy in children with pneumonia. Two review authors independently selected the studies to be included in the review, assessed trial quality and extracted data. Results: Three RCTs involving 255 inpatient children are included in the review. They addressed conventional chest physiotherapy, positive expiratory pressure and continuous positive airway pressure. The following outcomes were measured: duration of hospital stay, time to clinical resolution (observing the following parameters: fever, chest indrawing, nasal flaring, tachypnoea and peripheral oxygen saturation levels), change in adventitious sounds, change in chest X-ray and duration of cough in days. Two of the included studies found a significant improvement in respiratory rate and oxygen saturation whereas the other included study failed to show that standardised respiratory physiotherapy and positive expiratory pressure decrease the time to clinical resolution and the duration of hospital stay. No adverse effects related to the interventions were xvi described. Due to the different characteristics of the trials, such as the duration of treatment, levels of severity, types of pneumonia and the techniques used in children with pneumonia, as well as differences in their statistical presentation, we were not able to pool data. Two included studies had an overall low risk of bias whereas one included study had an overall unclear risk of bias. Conclusion: Our review does not provide conclusive evidence to justify the use of chest physiotherapy in children with pneumonia due to a lack of data. The number of included studies is small and they differed in their statistical presentation

Associação entre polimorfismos em enzimas de reparo de DNA e ocorrência de meningite bacteriana.

Despite advances in vaccine development and therapy, bacterial meningitis (BM) remains a major cause of death and long-term neurological disabilities. As part of the host inflammatory response to the invading pathogen, factors such as reactive oxygen species are generated, which may damage DNA and trigger the overactivation of DNA repair mechanisms. It is conceivable that the individual susceptibility and outcome of BM may be in part determined by non synonymous polymorphisms that may alter the function of crucial BER DNA repair enzymes as PARP-1, OGG-1 and APE-1. These enzymes, in addition to their important DNA repair function, also perform role of inflammatory regulators. In this work was investigated the non synonymous SNPs APE-1 Asn148Glu, OGG-1 Ser326Cys,PARP-1 Val762Ala, PARP-1 Pro882Leu and PARP-1 Cys908Tyr in patients with bacterial meningitis (BM), chronic meningitis (CM), aseptic meningitis (AM) and not infected (controls). As results we found increased frequency of variant alleles of PARP-1 Val762Ala (P = 0.005) and APE-1 Asn148Glu (P=0.018) in BM patients, APE-1 Asn148Glu in AM patients (P = 0.012) and decrease in the frequency of the variant allele OGG-1 Ser326Cys in patients with CM (P = 0.013), regarding the allelic frequencies in the controls. A major incidence of individuals heterozygous and/ or polymorphic homozygous in BM for PARP-1 Val762Ala (P= 0.0399, OD 4.2, 95% IC 1.213 -14.545) and PARP-1 Val762Ala/ APE-1 Asn148Glu (P = 0.0238, OD 11.111, 95% IC 1.274 - 96.914) was observed related to what was expected in a not infected population. It was also observed a major incidence of combined SNPs in the BM patients compared with the control group (P=0.0281), giving evidences that SNPs can cause some susceptibility to the disease. This combined effect of SNPs seems to regulate the principal cytokines and other factors related to BM inflammatory response and point the importance of DNA repair not only to repair activity when DNA is damaged, but to others essential functions to human organism balance.

O significado da morte para adolescentes, adultos e idosos

Apesar do aumento na quantidade de trabalhos que visam a abordar a morte como tema de investigação, observa-se que ainda prevalece a interdição do assunto morte, dificultando que ela seja abordada e discutida. Este estudo buscou ampliar a compreensão de como pessoas, em diferentes etapas desenvolvimentais, lidam com perdas e com a própria finitude. Para isso, 7 adolescentes, 14 adultos de meia-idade e 10 idosos foram entrevistados, e os dados foram compreendidos mediante análise de conteúdo. Entre os participantes, os adultos foram os que mostraram mais aflição e inquietação, ao falarem sobre a própria finitude e sobre a possibilidade da morte de pessoas queridas. Os adolescentes abordaram-na como um acontecimento distante e impessoal, enquanto os idosos se referiram a ela com maior proximidade e aceitação. Sugere-se a realização de estudos que aprofundem tais compreensões, relacionando-as às diferentes religiões, classes sociais e experiências com perdas.

O médico diante da morte na urgência e emergência:reflexões sobre o ser médico

The literature pointed that the way which people deal with death have been changing along centuries, and nowadays what is realized it is that, each time more, the human being have difficulties to deal with death. Due to the fact that the main function of the physician is to save their patients lives; responsibility that is aggravated by the necessity of to take decisions quickly, once he need to deal with the unexpected situations of the urgency and emergency, many times these professional have to face of impotency and fail situations, when he lose a patient. The main goal of this study was to understand the experience of physicians that work in the urgency and emergency, in front of death. These questioning it justified by the fact of the physicians do not have, many times, a space to express their suffering and anguish about the issues related to death in their work routine, despite lifedeath question to be often present their everyday. It is still possible to verify in the literature, an appointment of the necessity of to include in the curriculum of Medicine courses, subjects that approach such questions. The method used was based on the existential-phenomenological perspective, using as instrument the participant observation, to the intent of understand the routine in the urgency and emergency context, and semi-structured interview. It was interviewed six physicians that work in the urgency and emergency of the most important hospital of public health system of Natal-RN. The results showed that the physicians reported pleasure in work in the urgency and emergency, despite of they presented stress and the difficulties that they deal with in the public system. Despite of the fact that the death to be considered as a phenomenon that make part of the physician s routine, sometimes, deals with these one is more difficult. Many times losses generate an impotency and guilty feeling, as well as questionings about their performance during the attempts to save lives. We verified, from this study, the importance of the existence of some kind of intervention in the emergency, in order to the physicians can elaborate the questions about death and die emerged in their work. We consider yet that this study corroborates and reiterates the discussions concerning the importance of this thematic to be approached in a more effective way, during the academic formation of these professionals, as well as, the importance of a larger investment from the part of Government in the urgency and emergency sector, in order to propitiate to these professionals a work that brings less harmful for their health

O oncologista clínico diante da morte: implicações para a produção do cuidado

It is undeniable that all the extraordinary technological advances in contemporary society have increased the severe patients expectation and quality of life, especially cancer patients. On the other hand, it is easily verifiable by many researches that it was not possible to advance in the same proportion in caring for the human experience of death. Much is said about the anguish of a man facing death, of cancer patients in terminal stage, about their families, and very little about the feelings, anxieties and ways of coping with the medical professional who deals with this situation, specifically the clinical oncologist. Little is known about the experience of the doctor who has learned to take death as an enemy to be defeated, and increasingly is compelled to live at length with his advertisement. However, we started to watch in recent years a growing interest of researchers in this issue. This study seeks to add to this interest in order to understand the experience of clinical oncologists that accompany dying patients, the meanings they attach to death, ways of coping and the implications for providing care. This is a qualitative study in which was used as a tool for data collection an in-depth interview with the projective using script and scenes. Gadameriana Hermeneutics was used for analysis and interpretation of narratives. The subjects were 10 clinical oncologists who work at two institutions from cancer treatments in the state of Rio Grande do Norte, chosen from a variation in the time working in the specialty (minimum of one year, even old ones). However, you can bring some initial results for the dialogue. It was found that the death is still a topic that causes many difficulties in the daily lives of these professionals, the choice for oncology involves dealing with death without preparation in medical education; being close to the patient in the final moment, supporting the family, coping with own pain of loss and the inability to heal. These are central elements of the narratives. We also have investment in medical training and continuing education in setting up a demand that permeates the discourse of participants. Being able to listen to the subjective world of clinical oncologists will support the work not only for them as other professionals who deal with patients with advanced cancer, providing evidence to understand to what extent the meanings attributed to its know-how before patients on the verge of death interfere with the production of care and allow identify coping strategies in everyday life of these professionals that hinder or facilitate coping with death, promote or preclude the care with others and with themselves. It is hoped that research can contribute to the field of knowledge about the know-how in clinical oncology and their terminal-care-death oncologist-patient relationships, bringing runways capable of promoting a better quality of care in the production of all involved in this process: professionals, patients and families

Os agentes funerários e a morte: o cuidado presente diante da vida ausente

The present time is marked by the art of escape from death, which has become synonymous with failure, its exposure has become intolerable and the care of the dead body were assigned to third parties who market this practice through services and products that shape the market undertaker. In this context, in which death is an object of study, has arisen funeral officers, as professionals dealing with a dead body, with the pain of relatives and their reactions, often being the first to have contact with the death scene. As professionals in the health area, the morticians also deal with death. The first attempt to prevent the arrival of death, funeral officers already has begun their work routine from there. Death and its surrounding part of their profession. What about those professionals whose work demands as a feared and denied by society? This study aims to understand the intents, meanings and implications for the mortician to deal with death in their daily work in order to focus renewed attention to the care of these professionals. To this end, it was carried out a qualitative research grounded in the theoretical framework of Gadamerian hermeneutics for production and interpretation of narratives. It was used two methodological strategies for data collection: in-depth interview with script and workshop with the use of "scenes". Research participants were nine morticians funeral of two funeral agencies of the city of Natal. It was possible to detect the presence of the social imaginary of interdiction on the theme of death from living with feelings of his presence daily, from the need of respondents to naturalize their contacts with death, a requirement of their office to deal with the difficulties of manipulating body fluids and odors, sometimes in a state of decomposition; allied to wishes to achieve the goal of delivering to family-customers a "embellished" body for the final farewell. Being a mortician, in addition to not being a professional motivation, involves facing difficulties related to heavy routine work, low salaries, unprofitable work materials and equipments, besides having to deal with the social gaze that devalues the profession. In turn, they also deal with the pain coming especially from contact with family members, either when they are targets of these feelings of anger, whether they identify with the pain of the bereaved ones. On the other hand, when the recognition and gratitude of the families occur, they find meaning and beauty in their profession of caring for the dead body. The present study by giving voice to morticians has become possible to understand better their profession, the pain that surrounds and care needs of these workers. Finally, it has argued that the mortician may be recognized as a care professional for the way exercising caution with the dead body and their families.

Cuidados paliativos e ser-para-morte: reflexões sobre um atendimento psicológico

Death is a theme that fascinates, though at the same time, frightens and uneasy the human being, despite the finitude being present at our daily lives. In each historical time, death has been represented in a peculiar way, from familiar death (at Middle Ages), to interdicted death (at contemporary times). Through this path it‟s possible to recognize several attitudes and stages front of death and the process of dying as possibilities of coping and the understanding of these occurrences. In other hand, the palliative care proposal came as a humanized attention, front of the human finitude, recognizing death as a part of the vital cycle. The Brazilian reality, in this context, still faces a lot of political, economic and social barriers that makes difficult the consolidation of palliative care at the death process in the Brazilian Health Care policies. Currently, according to the Brazilian Palliative Care Association, Brazil presents an average of 40 services with this proposal. Such data portray our inexpressive condition in relation to these cares when considering the territorial extension and population of our country. Considering this scenario is relevant think about death and the process of dying at contemporary times, at a health context in which palliative care, when trying to humanize the process of dying, bring to light the issue of human finitude and the beingtowards- death, as thought by the philosopher Martin Heidegger. According to him, the human being (Dasein) is constituted as a being-towards-death, once death is its most own potentiality-for-bein and its last possibility to be lived. In view of the ideas presented, the proposed study appears as a qualitative research of existential-phenomenological inspiration and aims to understand the experience of being-toward-death from the psychological care to a person out of possibilities of cure living on palliative cares. The psychological care happened at the patient‟s home, understanding the clinical process of being-with-the-other from the written reports of the psychology/researcher, by the accompanying sessions, configured as an experience report. These reports are focused on the experiences lived by the patient, as well as apprehended by the psychologist at the intersubjectivity relation and its own experience with Dasein and, therefore, being-toward-death. The reports were hermeneutically interpreted, from the senses that emerged in this process, considering the notion of being-toward-death proposed by Heidegger. Furthermore, it was important to dialogue with other authors that approached the studied theme. It is perceived, through brief and meaningful reflections about the clinical treatments started, that the experience of illness with no possibilities of cure makes the Dasein revises feelings and experiences that were marked at the temporality and historicity of existence. It is a stage of life in which the cultural dimension and the common sense of finitude, often gains ground in the human condition, taken in its ordinary sense, unlike the way it has been thought from an ontological and existential perspective of death. Thus, there are singulars and revealing paths in the palliative care scenery as possible ways for authenticity of being-toward-death

Perfil de mortalidade de idosos no Rio Grande do Norte: estudo comparativo entre duas faixas etárias e fatores relacionados

Measures of mortality represent one of the most important indicators of health conditions. For comprising the larger rate of deaths, the study of mortality in the elderly population is regarded as essential to understand the health situation. In this sense, the present study aims to analyze the mortality profile of the population from 60 to 69 (young elders) and older than 80 years old (oldest old) in the Rio Grande do Norte state (Brazil) in the period 2001 to 2011, and to identify the association with contextual factors and variables about the quality of the Mortality Information System (SIM). For this purpose, Mortality Proportional (MP) was calculated for the state and Specific Mortality Rate by Age (CMId) , according to chapters of ICD- 10, to the municipalities of Rio Grande do Norte , through data from the Mortality Information System (SIM) and the Brazilian Institute of Geography and Statistics (IGBE). In order to identify groups of municipalities with similar mortality profiles, Nonhierarchical Clustering K-means method was applied and the Factor Analysis by the Principal Components Analysis was resort to reduce contextual variables. The spatial distribution of these groups and the factors were visualized using the Spatial Analysis Areas technique. During the period investigated, 21,813 younger elders deaths were recorded , with a predominance of deaths from circulatory diseases (32.75%) and neoplasms (22.9 %) . Among the oldest old, 50,637 deaths were observed, which 35.26% occurred because of cardiovascular diseases and 17.27% of ill-defined causes. Clustering Analysis produced three clusters to the two age groups and Factor Analysis reduced the contextual variables into three factors, also the sum of the factor scores was considered. Among the younger elders, the groups are called misinformation profile, development profile and development paradox, which showed a statistically significant association with education and poverty and extreme poverty factors, factorial sum and the variable related to underreporting of deaths. Misinformation profile remained in the oldest old group, accompanied by the epidemiological transition profile and the epidemiological paradox, that were statistically associated with the development and health factor, as well as with the variables that indicate the SIM quality: proportion of blank fields about the schooling and underreporting. It proposed that the mortality profiles of the younger elders and oldest old differ on the importance of the basic causes and that are influenced by different contextual aspects , observing that 60 to 69 years group is more affected by such aspects. Health inequalities can be reduced by measures aimed to improve levels of education and poverty, especially in younger elders, and by optimizing the use of health services, which is more associated to the oldest old health situation. Furthermore, it is important to improve the quality of information for the two age groups

Morte e filosofia: sobre o desejo de imortalidade entre os gregos

Enfoca-se aqui a vinculação íntima entre a exaustiva busca empreendida pelo espírito grego para edificar em terreno sólido as colossais fundações de uma ciência dos primeiros princípios, e o que supõe-se ser sua motivação secreta e última, a aspiração pela eternidade, o mais universal e genuíno desejo presente em todo ser humano, não ser obliterado pelo tempo.

Arcabouço geofísico, isostasia e causas do magmatismo cenozóico da província Borborema e de sua margem continental (Nordeste do Brasil)

The Borborema Province (BP) is a geologic domain located in Northeastern Brazil. The BP is limited at the south by the São Francisco craton, at the west by the Parnaíba basin, and both at the north and east by coastal sedimentary basins. Nonetheless the BP surface geology is well known, several key aspects of its evolution are still open, notably: i)its tectonic compartmentalization established after the Brasiliano orogenesis, ii) the architecture of its cretaceous continental margin, iii) the elastic properties of its lithosphere, and iv) the causes of magmatism and uplifting which occurred in the Cenozoic. In this thesis, a regional coverage of geophysical data (elevation, gravity, magnetic, geoid height, and surface wave global tomography) were integrated with surface geologic information aiming to attain a better understanding of the above questions. In the Riacho do Pontal belt and in the western sector of the Sergipano belt, the neoproterozoic suture of the collision of the Sul domain of the BP with the Sanfranciscana plate (SFP) is correlated with an expressive dipolar gravity anomaly. The positive lobule of this anomaly is due to the BP lower continental crust uplifting whilst the negative lobule is due to the supracrustal nappes overthrusting the SFP. In the eastern sector of the Sergipano belt, this dipolar gravity anomaly does not exist. However the suture still can be identified at the southern sector of the Marancó complex arc, alongside of the Porto da Folha shear zone, where the SFP N-S geophysical alignments are truncated. The boundary associated to the collision of the Ceará domain of the BP with the West African craton is also correlated with a dipolar gravity anomaly. The positive lobule of this anomaly coincides with the Sobral-Pedro II shear zone whilst the negative lobule is associated with the Santa Quitéria magmatic arc. Judging by their geophysical signatures, the major BP internal boundaries are: i)the western sector of the Pernambuco shear zone and the eastern continuation of this shear zone as the Congo shear zone, ii) the Patos shear zone, and iii) the Jaguaribe shear zone and its southwestern continuation as the Tatajuba shear zone. These boundaries divide the BP in five tectonic domains in the geophysical criteria: Sul, Transversal, Rio Grande do Norte, Ceará, and Médio Coreaú. The Sul domain is characterized by geophysical signatures associated with the BP and SFP collision. The fact that Congo shear zone is now proposed as part of the Transversal domain boundary implies an important change in the original definition of this domain. The Rio Grande do Norte domain presents a highly magnetized crust resulted from the superposition of precambrian and phanerozoic events. The Ceará domain is divided by the Senador Pompeu shear zone in two subdomains: the eastern one corresponds to the Orós-Jaguaribe belt and the western one to the Ceará-Central subdomain. The latter subdomain exhibits a positive ENE-W SW gravity anomaly which was associated to a crustal discontinuity. This discontinuity would have acted as a rampart against to the N-S Brasiliano orogenic nappes. The Médio Coreaú domain also presents a dipolar gravity anomaly. Its positive lobule is due to granulitic rocks whereas the negative one is caused by supracrustal rocks. The boundary between Médio Coreaú and Ceará domains can be traced below the Parnaíba basin sediments by its geophysical signature. The joint analysis of free air anomalies, free air admittances, and effective elastic thickness estimates (Te) revealed that the Brazilian East and Equatorial continental margins have quite different elastic properties. In the first one 10 km < Te < 20 km whereas in the second one Te ≤ 10 km. The weakness of the Equatorial margin lithosphere was caused by the cenozoic magmatism. The BP continental margin presents segmentations; some of them have inheritance from precambrian structures and domains. The segmentations conform markedly with some sedimentary basin features which are below described from south to north. The limit between Sergipe and Alagoas subbasins coincides with the suture between BP and SFP. Te estimates indicates concordantly that in Sergipe subbasin Te is around 20 km while Alagoas subbasin has Te around 10 km, thus revealing that the lithosphere in the Sergipe subbasin has a greater rigidity than the lithosphere in the Alagoas subbasin. Additionally inside the crust beneath Sergipe subbasin occurs a very dense body (underplating or crustal heritage?) which is not present in the crust beneath Alagoas subbasin. The continental margin of the Pernambuco basin (15 < Te < 25 km) presents a very distinct free air edge effect displaying two anomalies. This fact indicates the existence in the Pernambuco plateau of a relatively thick crust. In the Paraíba basin the free air edge effect is quite uniform, Te ≈ 15 km, and the lower crust is abnormally dense probably due to its alteration by a magmatic underplating in the Cenozoic. The Potiguar basin segmentation in three parts was corroborated by the Te estimates: in the Potiguar rift Te ≅ 5 km, in the Aracati platform Te ≅ 25 km, and in the Touros platform Te ≅ 10 km. The observed weakness of the lithosphere in the Potiguar rift segment is due to the high heat flux while the relatively high strength of the lithosphere in the Touros platform may be due to the existence of an archaean crust. The Ceará basin, in the region of Mundaú and Icaraí subbasins, presents a quite uniform free air edge effect and Te ranges from 10 to 15 km. The analysis of the Bouguer admittance revealed that isostasy in BP can be explained with an isostatic model where combined surface and buried loadings are present. The estimated ratio of the buried loading relative to the surface loading is equal to 15. In addition, the lower crust in BP is abnormally dense. These affirmations are particularly adequate to the northern portion of BP where adherence of the observed data to the isostatic model is quite good. Using the same above described isostatic model to calculate the coherence function, it was obtained that a single Te estimate for the entire BP must be lower than 60 km; in addition, the BP north portion has Te around 20 km. Using the conventional elastic flexural model to isostasy, an inversion of crust thickness was performed. It was identified two regions in BP where the crust is thickened: one below the Borborema plateau (associated to an uplifting in the Cenozoic) and the other one in the Ceará domain beneath the Santa Quitéria magmatic arc (a residue associated to the Brasiliano orogenesis). On the other hand, along the Cariri-Potiguar trend, the crust is thinned due to an aborted rifting in the Cretaceous. Based on the interpretation of free air anomalies, it was inferred the existence of a large magmatism in the oceanic crust surrounding the BP, in contrast with the incipient magmatism in the continent as shown by surface geology. In BP a quite important positive geoid anomaly exists. This anomaly is spatially correlated with the Borborema plateau and the Macaú-Queimadas volcanic lineament. The integrated interpretation of geoid height anomaly data, global shear velocity model, and geologic data allow to propose that and Edge Driven Convection (EDC) may have caused the Cenozoic magmatism. The EDC is an instability that presumably occurs at the boundary between thick stable lithosphere and oceanic thin lithosphere. In the BP lithosphere, the EDC mechanism would have dragged the cold lithospheric mantle into the hot asthenospheric mantle thus causing a positive density contrast that would have generated the main component of the geoid height anomaly. In addition, the compatibility of the gravity data with the isostatic model, where combined surface and buried loadings are present, together with the temporal correlation between the Cenozoic magmatism and the Borborema plateau uplifting allow to propose that this uplifting would have been caused by the buoyancy effect of a crustal root generated by a magmatic underplating in the Cenozoic

Síndromes hipertensivas da gestação: identificação de casos graves

A hipertensão arterial está entre as causas mais freqüentes de morte materna. Entre os tipos presentes na gravidez destacam-se as manifestações específicas, isto é, a pré-eclâmpsia e a hipertensão gestacional, definidas clinicamente por aumento dos níveis da pressão arterial após a 20ª semana de gestação, associado (pré-eclâmpsia) ou não (hipertensão gestacional) à proteinúria. Na fase inicial a doença é assintomática, porém, quando não tratada ou não se interrompe a gestação, sua evolução natural é desenvolver as formas graves, como a eclâmpsia e a síndrome HELLP. Eclâmpsia é definida pela manifestação de uma ou mais crises convulsivas tônico-clônicas generalizadas e/ou coma, em gestante com hipertensão gestacional ou pré-eclâmpsia, na ausência de doenças neurológicas. Pode ocorrer durante a gestação, durante o trabalho de parto e no puerpério imediato. É comumente precedida pelos sinais e sintomas de eclâmpsia iminente (distúrbios do sistema nervoso central, visuais e gástricos). A associação de hemólise, plaquetopenia e disfunção hepática já era relatada na literatura na década de cinqüenta. em 1982, Weinstein reuniu estas alterações sob o acrônimo de HELLP, significando hemólise (H), aumento de enzimas hepáticas (EL) e plaquetopenia (LP), e denominou-as de síndrome HELLP. A literatura diverge em relação aos valores dos parâmetros que definem a síndrome. Sibai et al. (1986) propuseram sistematização dos padrões laboratoriais e bioquímicos para o diagnóstico da mesma, que foi adotada pelo Ministério da Saúde do Brasil. As manifestações clínicas podem ser imprecisas, sendo comuns queixas como dor epigástrica, mal-estar geral, inapetência, náuseas e vômitos. O diagnóstico precoce é, eminentemente, laboratorial e deve ser pesquisado de maneira sistemática nas mulheres com pré-eclâmpsia grave/eclâmpsia e/ou dor no quadrante superior direito do abdome. Diferenciar a síndrome HELLP de outras ocorrências, com manifestações clínicas e/ou laboratoriais semelhantes, não é tarefa fácil. O diagnóstico diferencial é particularmente difícil para doenças como púrpura trombocitopênica trombótica, síndrome hemolítico-urêmica e fígado gorduroso agudo da gravidez, devido à insuficiente história clínica e à semelhança dos aspectos fisiopatológicos. O conhecimento da fisiopatologia da pré-eclâmpsia, o diagnóstico precoce e a atuação precisa no momento adequado nas situações complicadas pela eclâmpsia e/ou síndrome HELLP permitem melhorar o prognóstico materno e perinatal.

Monitorização da pressão intracraniana como exame complementar no diagnóstico de morte encefálica: observação preliminar através do registro de dois casos

Estudou-se retrospectivamente a evolução clínica de dois pacientes, até sua falência cardíaca irreversível (FCI), submetidos à monitorização contínua da pressão intracraniana (PIC). O estudo detalhado desses traçados mostrou que, nos dois casos a PIC atingiu valores máximos 5 e 12 h antes de ocorrer diminuição na amplitude das ondas, observada 47 e 60 h pré-FCI. Essa diminução foi progressiva e tornou-se linear cerca de 30 h antes da FCI, em ambos os casos. O diagnóstico clínico de morte encefálica (ME) foi obtido 3 e 28 hs após a linearidade do traçado. Os autores sugerem que o diagnóstico de ME pode ser definido mais precocemente com o uso da monitorização da PIC desde que o paciente não esteja sob sedação, e salientam a necessidade de mais observações, em número maior de pacientes.

Mortalidade de adolescentes em área urbana da região Sudeste do Brasil, 1984-1993

Analisa-se a mortalidade de adolescentes no Município de Botucatu, Estado de São Paulo, Brasil, no período de 1984 a 1993, segundo dois subgrupos (10 a 14 e 15 a 19 anos), sexo, ocupação e causas de óbito. Os dados de óbitos foram obtidos no Setor de Estatística do Centro de Saúde-Escola. As estimativas populacionais foram calculadas com base nos censos demográficos. Observou-se variação dos coeficientes de mortalidade nos diferentes anos e maior mortalidade no grupo masculino de 15 a 19 anos, atingindo tanto estudantes como trabalhadores. Houve predomínio de causas externas de mortalidade, principalmente acidentes de trânsito e ferimento por arma de fogo, exigindo averigüação de seus determinantes e o desenvolvimento de programas de saúde destinados aos adolescentes, suas famílias e à sociedade, considerando-se que as causas de morte são evitáveis e preveníveis.

De que adoecem e morrem as mulheres em São Paulo

O estudo traça um perfil da morbi-mortalidade feminina no Estado de São Paulo, com enfoque nos problemas reprodutivos. A mortalidade foi estudada nos períodos 1979-81; 1986-88 e 1993-5, a partir do Sistema de Informação em Mortalidade (SIM/DATASUS) e a morbidade de 1996 foi obtida do Sistema de Informações Hospitalares (SIH/DATASUS). O artigo discute as principais causas de internação e morte das mulheres e aponta os desafios para as políticas públicas voltadas a saúde da mulher.
