Resultados da Angioplastia Prim��ria num Centro de Refer��ncia. Evolu����o Intra-Hospitalar

INTRODUCTION: Primary angioplasty is accepted as the preferred treatment for acute myocardial infarction in the first 12 hours. However, outcomes depend to a large extent on the volume of activity and experience of the center. Continuous monitoring of methods and results obtained is therefore crucial to quality control. OBJECTIVE: To describe the demographic, clinical and angiographic characteristics as well as in-hospital outcomes of patients undergoing primary PCI in a high-volume Portuguese center. We also aimed to identify variables associated with in-hospital mortality in this population. METHODS: This was a retrospective registry of consecutive primary PCIs performed at Santa Marta Hospital between January 2001 and August 2007. Demographic, clinical, and angiographic characteristics and in-hospital outcomes were analyzed. Independent predictors of in-hospital mortality were identified by multivariate logistic regression analysis. RESULTS: A total of 1157 patients were identified, mean age 61+/-12 years, 76% male. Mean pain-to-balloon time was 7.6 hours and primary angiographic success was 88%. Overall in-hospital mortality was 6.9%, or 5.5% if patients presenting in cardiogenic shock were excluded from the analysis. Previous history of heart failure, cardiogenic shock on admission, invasive ventilatory support, major hemorrhage, and age over 75 years were found to be associated with increased risk of in-hospital death. Conclusions: In this center primary PCI is effective and safe. Angiographic success rates and in-hospital mortality and morbidity are similar to other international registries. Patients at increased risk for adverse outcome can be identified by simple clinical characteristics such as advanced age, cardiogenic shock on admission, mechanical ventilation and major hemorrhage during hospitalization.

Hospitaliza����o em Crian��as com Infec����o por Rotav��rus

Introdu����o. A infec����o por rotav��rus �� a principal causa de diarreia aguda em todo o mundo. Nos pa��ses desenvolvidos n��o constitui uma causa importante de morte, mas cursa com uma alta morbilidade. Objectivo. Caracterizar a infec����o por rotav��rus em crian��as hospitalizadas em dois Departamentos de Pediatria de Lisboa. Material e m��todos. Revis��o casu��stica dos internamentos com o diagn��stico de infec����o por rotav��rus, num hospital central especializado e num hospital geral na Zona Metropolitana de Lisboa, entre Janeiro e Dezembro de 2005. O diagn��stico foi efectuado atrav��s da identifica����o de antig��nios virais nas fezes por ���enzyme immunoassay���. Resultados. Foram analisados 92 casos; 82% ocorreram entre Dezembro e Mar��o e 52,8% em crian��as entre os tr��s e os doze meses. Em metade dos casos registou-se bom n��vel socio-econ��mico. Os factores de risco epidemiol��gicos encontrados foram: frequ��ncia de institui����o de ensino ou ama em 21/38 (55%), contacto com pessoas com sintomatologia semelhante em 10/53 (19%) e irm��os com idade inferior a cinco anos em 25/76 (33%) das crian��as. As infec����es nosocomiais foram respons��veis por 26% dos casos estudados. A cl��nica cursou com: diarreia aquosa (96%), v��mitos (87%) e febre (69%). Ocorreram complica����es em 19/92 (21%) crian��as e estas foram mais frequentes em lactentes com menos de seis meses de idade (35% vs. 16%, p=0,058). A mediana da dura����o de internamento foi cinco dias e o custo hospitalar directo variou entre 629,63 e 2342,38 euros. Discuss��o. O n��mero de internamentos por infec����o por rotav��rus, especialmente em lactentes, a frequ��ncia de infec����es nosocomiais por este agente, as complica����es inerentes e os elevados custos, reflectem a import��ncia da infec����o por este agente em pa��ses desenvolvidos como Portugal.

Prevalence and associated risk factors for Giardia lamblia infection among children hospitalized for diarrhea in Goi��nia, Goi��s State, Brazil

The objective of this study was to determine the prevalence and to identify risk factors associated with Giardia lamblia infection in diarrheic children hospitalized for diarrhea in Goi��nia, State of Goi��s, Brazil. A cross-sectional study was conducted and a comprehensive questionnaire was administered to the child's primary custodian. Fixed effects logistic regression was used to determine the association between infection status for G. lamblia and host, sociodemographic, environmental and zoonotic risk factors. A total of 445 fecal samples were collected and processed by the DFA methodology, and G. lamblia cysts were present in the feces of 44 diarrheic children (9.9%). A variety of factors were found to be associated with giardiasis in these population: age of children (OR, 1.18; 90% CI, 1.0 - 1.36; p = 0.052), number of children in the household (OR 1.45; 90% CI, 1.13 - 1.86; p = 0.015), number of cats in the household (OR, 1.26; 90% CI, 1.03 -1.53; p = 0.059), food hygiene (OR, 2.9; 90% CI, 1.34 - 6.43; p = 0.024), day-care centers attendance (OR, 2.3; 90% CI, 1.20 - 4.36; p = 0.034), living on a rural farm within the past six months prior hospitalization (OR, 5.4; CI 90%, 1.5 - 20.1; p = 0.03) and the number of household adults (OR, 0.59; 90% CI, 0.42 - 0.83; p = 0.012). Such factors appropriately managed may help to reduce the annual incidence of this protozoal infection in the studied population.

Fatal septicemia caused by Chromobacterium violaceum in a child from Colombia

A 4-year old child living in Colombia presented with a history of fever and severe abdominal pain for four days. The patient developed pneumonia, septic shock, multiple organ failure and died on the fifth day of hospitalization. Chromobacterium violaceum was isolated from admission blood cultures and was resistant to ampicillin, cephalosporins, carbapenems and aminoglycosides.

Aids-related progressive multifocal leukoencephalopathy: a retrospective study in a referral center in S��o Paulo, Brazil

Few data are available about progressive multifocal leukoencephalopathy (PML) in patients with acquired immunodeficiency syndrome (AIDS) from Brazil. The objectives of this study were to describe the main features of patients with PML and estimate its frequency among AIDS patients with central nervous system (CNS) opportunistic diseases admitted to the Instituto de Infectologia Em��lio Ribas, S��o Paulo, Brazil, from April 2003 to April 2004. A retrospective and descriptive study was performed. Twelve (6%) cases of PML were identified among 219 patients with neurological diseases. The median age of patients with PML was 36 years and nine (75%) were men. Nine (75%) patients were not on antiretroviral therapy at admission. The most common clinical manifestations were: focal weakness (75%), speech disturbances (58%), visual disturbances (42%), cognitive dysfunction (42%), and impaired coordination (42%). The median CD4+ T-cell count was 45 cells/��L. Eight (67%) of 12 patients were laboratory-confirmed with PML and four (33%) were possible cases. Eleven (92%) presented classic PML and only one case had immune reconstitution inflammatory syndrome (IRIS)-related PML. In four (33%) patients, PML was the first AIDS-defining illness. During hospitalization, three patients (25%) died as a result of nosocomial pneumonia and nine (75%) were discharged to home. Cases of PML were only exceeded by cases of cerebral toxoplasmosis, cryptococcal meningoencephalitis, and CNS tuberculosis, the three more frequent neurologic opportunistic infections in Brazil. The results of this study suggest that PML is not an uncommon HIV-related neurologic disorder in a referral center in Brazil.

Candida bloodstream infection: data from a teaching hospital in Mato Grosso do Sul, Brazil

The incidence of Candida bloodstream infection has increased over the past years. In the Center-West region of Brazil, data on candidemia are scarce. This paper reports a retrospective analysis of 96 cases of Candida bloodstream infection at a Brazilian tertiary-care teaching hospital in the state of Mato Grosso do Sul, from January 1998 to December 2006. Demographic, clinical and laboratory data were collected from medical records and from the hospital's laboratory database. Patients' ages ranged from three days to 92 years, with 53 (55.2%) adults and 43 (44.8%) children. Of the latter, 25 (58.1%) were newborns. The risk conditions most often found were: long period of hospitalization, utilization of venous central catheter, and previous use of antibiotics. Fifty-eight (60.4%) patients died during the hospitalization period and eight (13.7%) of them died 30 days after the diagnosis of candidemia. Candida albicans (45.8%) was the most prevalent species, followed by C. parapsilosis (34.4%), C. tropicalis (14.6%) and C. glabrata (5.2%). This is the first report of Candida bloodstream infection in the state of Mato Grosso do Sul and it highlights the importance of considering the possibility of invasive Candida infection in patients exposed to risk factors, particularly among neonates and the elderly.

Acute postsurgical suppurative parotitis: current prevalence at Hospital das Cl��nicas, S��o Paulo University Medical School

Postsurgical acute suppurative parotitis is a bacterial gland infection that occurs from a few days up to some weeks after abdominal surgical procedures. In this study, the authors analyze the prevalence of this complication in Hospital das Cl��nicas/S��o Paulo University Medical School by prospectively reviewing the charts of patients who underwent surgeries performed by the gastroenterological and general surgery staff from 1980 to 2005. Diagnosis of parotitis or sialoadenitis was analyzed. Sialolithiasis and chronic parotitis previous to hospitalization were exclusion criteria. In a total of 100,679 surgeries, 256 patients were diagnosed with parotitis or sialoadenitis. Nevertheless, only three cases of acute postsurgical suppurative parotitis associated with the surgery were identified giving an incidence of 0.0028%. All patients presented with risk factors such as malnutrition, immunosuppression, prolonged immobilization and dehydration. In the past, acute postsurgical suppurative parotitis was a relatively common complication after major abdominal surgeries. Its incidence decreased as a consequence of the improvement of perioperative antibiotic therapy and postoperative support. In spite of the current low incidence, we believe it is important to identify risks and diagnose as quick as possible, in order to introduce prompt and appropriate therapeutic measures and avoid potentially fatal complications with the evolution of the disease.

O regresso a casa ap��s hospitaliza����o : an��lise da prepara����o da alta de enfermagem no caso particular da pessoa idosa aut��noma��

RESUMO: O envelhecimento demogr��fico �� uma realidade dos nossos dias. A prepara����o da alta de enfermagem �� um elemento da presta����o de cuidados que pode ser explorado na fase de envelhecimento para dotar os idosos de conhecimentos, capacidades e responsabilidade na gest��o da sua condi����o de sa��de. Deste modo delineou-se um estudo de tipo descritivo, transversal e explorat��rio com o objectivo de analisar e compreender o processo de prepara����o da alta hospitalar de enfermagem ao idoso internado por agudiza����o de doen��a, que se apresente aut��nomo no momento da alta, de modo a capacit��-lo para a gest��o da sua condi����o de sa��de. O estudo decorreu num Servi��o de Medicina Interna. Definiu-se como fontes de informa����o e m��todos de colheita de dados 25 entrevistas a idosos, 16 question��rios abertos a enfermeiros prestadores de cuidados e an��lise dos registos do processo de internamento dos idosos. Como principais resultados destacamos que os idosos quando internados apresentam preocupa����es relacionadas com a sua condi����o de sa��de e o motivo de internamento, os quais s��o pouco valorizadas na prepara����o da alta; os cuidados com a sa��de que os idosos t��m antes do internamento s��o valorizados nos registos de enfermagem; um ter��o dos idosos n��o teve conhecimento do seu diagn��stico m��dico; os diagn��sticos de enfermagem activos no momento da alta n��o s��o contemplados na prepara����o da alta; os idosos com a aproxima����o do regresso a casa manifestam preocupa����es sobre os cuidados a ter com a sua sa��de e manifestam interesse em ser informados sobre os mesmos; os idosos sentem pouca disponibilidade por parte dos enfermeiros para a prepara����o da alta; as interven����es de prepara����o da alta centram-se em interven����es do tipo ensinar, instruir e treinar, tendo-se verificado discrep��ncias sobre os cuidados prestados e o seu conte��do sob as v��rias fontes de informa����o; o di��logo �� a estrat��gia de prepara����o da alta que prevalece; mais informa����o e informa����o escrita s��o aspectos que podem melhorar a prepara����o da alta segundo os idosos. Podemos assim concluir que n��o existe uma estrutura de prepara����o da alta a idosos com capacidade para gerir a sua condi����o de sa��de e que muito pode ser melhorado em termos de prepara����o da alta a idosos no sentido de tomar o m��ximo partido deste elemento dos cuidados e assim obter ganhos em sa��de. ----------- ABSTRACT: The demographic aging is a reality nowadays. The nursing discharge planning is an element of care that should be studied on aging to provide older people with knowledge, abilities and responsibility in order to deal their health condition. Thus, it was outlined a descriptive study, transversal and exploratory in order to analyze and understand how the process nursing discharge occurs, by planning the elderly hospitalized with acute disease, in order to support patients for better management of health conditions. The study was carried in an Internal Medicine Service of a Central Hospital. As information sources and methods of data collection, we defined 25 interviews with elderly, 16 open-ended questionnaires to nurses and analysis of records from the process of the elderly hospitalized. In the main results we observe the elderly hospitalized have concerns about their health condition and the reason for their hospitalization, which are undervalued in the discharge planning process; the health care reported by elderly related to time before hospitalization were registered in nursing records; one-third of the elderly don���t know the medical diagnosis; the active nursing diagnosis at discharge assets are not included in the discharge planning process; in the discharge, the elderly had concerns over the care of their health and expressed interest in being informed of it; the elderly don���t feel availability from the nurses in the discharge planning; the discharge interventions focus on interventions like teaching, instructing and training, and there have been different views about the care provided and its contents under the various sources of information; the high prevailing strategy to discharge planning is the dialogue; more information and written information are aspects that can improve the discharge planning process. We conclude that there is no structure in discharge planning for the elderly with high ability to manage his health condition. There are several things that can be improved to the discharge planning for the elderly in order to take full advantage of this element of care.

Pseudo-outbreak of Clostridium difficile associated diarrhea (CDAD) in a tertiary-care hospital

The objective of this study was to describe a pseudo-outbreak of C. difficile in a hospital, following a change in the method used to detect the toxin. In February 2002, there were two cases of CDAD and in March 7 occurred, coinciding with a change of the test (from detection of toxin A to toxin A/B). An outbreak was suspected. Active surveillance and education of staff were started. A CDAD case was defined as a patient with acute onset of diarrhea (�� three episodes of liquid stools) and a positive stool test. They were classified as hospital or community-acquired. Stool samples were also collected for C. difficile culture and isolates were typed using AP-PCR. From March 2002 through December 2003 there were 138 cases of CDAD: 70% were hospital-acquired and among the 30% with CDAD present on admission, most (81%) came directly from the community (50% had no history of hospitalization). Fifty-two percent of hospital-acquired CDAD and 94% of cases on admission had already used antibiotics. The incidence of CDAD in hospitalized patients during surveillance was 3.3 per 1000 patient-admissions. The incidence of CDAD present on admission was 6.1/1000 patients. Sixteen isolates were typed and presented 13 different profiles. In conclusion, the CDAD increase in our study occurred due to change in diagnostic methods and not due to an outbreak, as suspected initially. The incidence in hospitalized patients was much lower than in reported outbreaks. There were 13 molecular types suggesting that an outbreak did not occur. CDAD was largely community-acquired.

Dengue in an elderly patient

Although elderly populations are more exposed to the risk of getting dengue, the clinical peculiarities of this disease in this age range are not well known. This report is about an 80-year-old woman with dengue complications, self-medicated with salicylate. Literature indicates a more severe clinical condition, high hospitalization rate and significant mortality. This is caused by previous infections by other serotypes of this arbovirus, presence of chronic diseases, immunosenescence and high drug consumption, especially salicylates and the like. Analyses are required in a public health perspective in order to help health professionals that care for patients with dengue in this age range.

Acute inflammatory demyelinating polyradiculoneuropathy (Guillain-Barr�� syndrome) following dengue fever

This paper reports a case of dengue in a six-year-old female child who suddenly developed excruciating headaches, fever, myalgia and paresis. Laboratory examinations included blood count, platelet count, biochemical tests (BUN, creatinine, aminotransferases, and total bilirubin and bilirubin fractions) and specific IgM titers (enzyme-immunoassay with recombinant tetravalent dengue). After ten days of hospitalization and having already been in a home environment, a new clinical image emerged, characterized by dysphagia, dysphonia, weakness, peripheral facial palsy and paresthesia. The diagnosis of Guillain-Barr�� Syndrome was based on clinical findings, cerebrospinal fluid examination, electrophysiological findings and the exclusion of other pathologies. Our case, as some shown in previous reports, calls attention to the possibility that Guillain-Barr�� Syndrome may occur in association with dengue.

Identification of respiratory virus in infants with congenital heart disease by comparison of different methods

Respiratory virus infections are the main cause of infant hospitalization and are potentially severe in children with congenital heart disease (CHD). Rapid and sensitive diagnosis is very important to early introduction of antiviral treatment and implementation of precautions to control transmission, reducing the risk of nosocomial infections. In the present study we compare different techniques in the diagnosis of respiratory viruses in CHD infants. Thirty-nine samples of nasopharyngeal aspirate were obtained from CHD infants with symptoms of respiratory infection. The Multiplex PCR (Seeplex�� RV 12 ACE Detection) driven to the detection of 12 respiratory viruses was compared with the direct immunofluorescence assay (DFA) and PCR, both targeting seven respiratory viruses. The positivity found by DFA, Multiplex and PCR was 33.3%, 51.3% and 48.7%, respectively. Kappa index comparing DFA and Multiplex, DFA and PCR and PCR and Multiplex PCR was 0.542, 0.483 and 0.539, respectively. The concordance between techniques was considered moderate. Both Multiplex PCR (p = 0.001) and PCR (p = 0.002) detected significantly more respiratory virus than DFA. As the performance of the tests may vary, the combination of two or more techniques may increase diagnostic sensitivity favoring the diagnosis of co-infections, early introduction of antiviral therapy and implementation of appropriate measures.

SEPTIC SHOCK IN PATIENT WITH DISSEMINATED HISTOPLASMOSIS ASSOCIATED WITH AIDS: A CASE REPORT

SUMMARY Histoplasmosis is a systemic mycosis caused by Histoplasma capsulatum, which may present itself as a serious infection in immunocompromised individuals. We present a case of 31-year-old female with newly diagnosed HIV infection and history of fever, general and respiratory symptoms and diffuse hyperchromic papules through the body. She was admitted, with rapid progression to septic shock, and the presence of neutrophils filled with yeast-like organisms was detected on peripheral blood smear hematoscopia on the third day of hospitalization. The following is a brief review on the clinical picture and management of histoplasmosis.

HISTORICAL SERIES OF PATIENTS WITH VISCERAL LEISHMANIASIS TREATED WITH MEGLUMINE ANTIMONIATE IN A HOSPITAL FOR TROPICAL DISEASES, MACEI��-AL, BRAZIL

Introduction: Visceral leishmaniasis is an endemic protozoan found in Brazil. It is characterized by fever, pallor, hepatosplenomegaly, lymphadenopathy, and progressive weakness in the patient. It may lead to death if untreated. The drug of choice for treatment is meglumine antimoniate (Glucantime®). The aim of this study was to evaluate patients with visceral leishmaniasis according to criteria used for diagnosis, possible reactions to Glucantime® and blood pressure measured before and after treatment. Methods: 89 patients admitted to the Teaching Hospital Dr. Hélvio Auto (HEHA) in Maceió-AL, in the period from May 2006 to December 2009 were evaluated. Data were collected on age, sex, origin, method of diagnosis, adverse effects of drugs, duration of hospitalization, duration of treatment and dosage up to the onset of adverse effects. Results: There was a predominance of child male patients, aged between one and five years old, from the interior of the State of Alagoas. Parasitological diagnosis was made by bone marrow aspirate; three (3.37%) patients died, 12 (13.48%) had adverse reactions and treatment was changed to amphotericin B, and 74 (83.14%) were cured. Changes that led to replacing Glucantime® were persistent fever, jaundice, rash, bleeding and cyanosis. Conclusion: During the study, 89 patients hospitalized for VL were analyzed: 74 were healed, 12 were replaced by amphotericin B treatment and three died. Most of them were under five years old, male and came from the interior. The dosage and duration of treatment with Glucantime® were consistent with that advocated by the Ministry of Health. Persistence of fever, jaundice, rash, cyanosis and bleeding were the reactions that led the physician to modify treatment. No change was observed in blood pressure before and after treatment. This study demonstrated the work of a hospital, a reference in the treatment of leishmaniasis, which has many patients demanding its services in this area. It demonstrates that this disease is still important today, and needs to be addressed properly to prevent injury and death due to the disease.

A Prospective Assessment of Renal Transplantation Versus Haemodialysis: Which Therapeutic Modality Is Good Value for Society?

Background: Economic evaluations help health authorities facing budget constraints. This study compares the health-related quality of life (HRQOL) and costs in patient subgroups on haemodialysis (HD) and renal transplantation (KT). Methods: In a prospective study with follow-up of 1-3 years, we performed a costutility analysis of KT vs. HD, adopting a lifetime horizon. A societal perspective was taken. Costs for organ procurement, KT eligibility, transplant surgery and follow-up of living donors were included. Key clinical events were recorded. HRQOL was assessed using the EuroQol instrument. Results: The HRQOL remained stable on HD patients. After KT, mean utility score improved at 3 months while mean EQ-VAS scores showed a sustained improvement. Mean annual cost for HD was 32,567.57���. Mean annual costs for KT in the year-1 and in subsequent years were, 60,210.09��� and 12,956.77��� respectively. Cost for initial hospitalization averaged 18,740.74���. HLA-mismatches increased costs by 75% for initial hospitalization (p < 0.001) and 41% in the year-1 (p < 0.05), and duplicate the risk of readmission in the year-1 (p < 0.05). The incremental costutility ratio was 5,534.46���/QALY, increasing 35% when costs for organ procurement were added. KT costs were 41,541.63��� more but provided additional 7.51 QALY. Conclusions: The KT is cost-effective compared with HD. Public funding should reflect the value created by the intervention and adapt to the organ demand.
