Poisoning due to Philodryas olfersii (Lichtenstein, 1823) attended at Restauração Hospital in Recife, State of Pernambuco, Brazil: case report

Few papers have been published on snake bites caused by Philodryas olfersii. We report here the first case identified at the Centro de Assistência Toxicológica do Hospital da Restauração, Recife, State of Pernambuco. This case was described based on medical protocols, interviewing the patient and identifying the animal that caused the bite. The patient presented pain, heat, erythema, edema and ecchymosis, without other laboratory abnormalities or coagulation disorders. The treatment consisted of administration of eight ampoules of antibothropic serum, and post-administration allergenic reactions were observed. The importance of bites by opistoglyph snakes needs to be reconsidered in research and at specialized treatment centers.

Lessons from the epidemiological surveillance program, during the influenza A (H1N1) virus epidemic, in a reference university hospital of Southeastern Brazil

INTRODUCTION: The case definition of influenza-like illness (ILI) is a powerful epidemiological tool during influenza epidemics. METHODS: A prospective cohort study was conducted to evaluate the impact of two definitions used as epidemiological tools, in adults and children, during the influenza A H1N1 epidemic. Patients were included if they had upper respiratory samples tested for influenza by real-time reverse transcriptase polymerase chain reaction during two periods, using the ILI definition (coughing + temperature > 38ºC) in period 1, and the definition of severe acute respiratory infection (ARS) (coughing + temperature > 38ºC and dyspnoea) in period 2. RESULTS: The study included 366 adults and 147 children, covering 243 cases of ILI and 270 cases of ARS. Laboratory confirmed cases of influenza were higher in adults (50%) than in children (21.6%) ( p < 0.0001) and influenza infection was more prevalent in the ILI definition (53%) than ARS (24.4%) (p < 0.0001). Adults reported more chills and myalgia than children (p = 0.0001). Oseltamivir was administered in 58% and 46% of adults and children with influenza A H1N1, respectively. The influenza A H1N1 case fatality rate was 7% in adults and 8.3% in children. The mean time from onset of illness until antiviral administration was 4 days. CONCLUSIONS: The modification of ILI to ARS definition resulted in less accuracy in influenza diagnosis and did not improve the appropriate time and use of antiviral medication.

Impact of an intervention in the use of sequential antibiotic therapy in a Brazilian university hospital

INTRODUCTION: Sequential antibiotic therapy (SAT) is safe and economical. However, the unnecessary use of intravenous (IV) administration usually occurs. The objective of this work was to get to know the effectiveness of an intervention to implement the SAT in a teaching hospital in Brazil. METHODS: This was a prospective and interventional study, historically controlled, and was conducted in the Hospital de Clínicas, Universidade Federal de Uberlândia, State of Minas Gerais, Brazil, a high complexity teaching hospital having 503 beds. In each of the periods, from 04/04/05 to 07/20/05 (pre-intervention) and from 09/24/07 to 12/20/07 (intervention), 117 patients were evaluated. After the pre-intervention period, guidelines were developed which were implemented during the intervention period along with educational measures and a reminder system added to the patients' prescription. RESULTS: In the pre-intervention and intervention periods, the IV antibiotics were used as treatment for a average time of 14.8 and 11.8 days, respectively. Ceftriaxone was the antibiotic most prescribed in both periods (23.4% and 21.6% respectively). Starting from the first prescription of antibiotics, the average length of hospitalization time was 21.8 and 17.5 days, respectively. The SAT occurred only in 4 and 5 courses of treatment, respectively, and 12.8% and 18.8% of the patients died in the respective periods. CONCLUSIONS: Under the presented conditions, the evaluated intervention strategy is ineffective in promoting the exchange of the antibiotic administration from IV to oral treatment (SAT).

Prenatal tracheal ligation or intra-amniotic administration of surfactant or dexamethasone prevents some structural changes in the pulmonary arteries of surgically created diaphragmatic hernia in rabbits

PURPOSE: Characterization of the structural changes occurring in the pulmonary arteries resulting from surgically produced congenital diaphragmatic hernia in rabbits, with particular emphasis on the preventive effects of prenatal tracheal ligation or administration of intra-amniotic dexamethasone or surfactant. METHODS: Twenty rabbit fetuses underwent surgical creation of a left-sided congenital diaphragmatic hernia on the 24th or 25th gestational day. They were divided according to the following procedures: congenital diaphragmatic hernia (n = 5), congenital diaphragmatic hernia plus tracheal ligation (n = 5), congenital diaphragmatic hernia plus intra-amniotic administration of dexamethasone 0.4 mg (n = 5) or surfactant (Curosurf 40 mg, n = 5). On gestational day 30, all the fetuses were delivered by caesarean section and killed. A control group consisted of five nonoperated fetuses. Histomorphometric analysis of medial thickness, cell nuclei density, and elastic fiber density of pulmonary arterial walls was performed. RESULTS: Arteries with an external diameter > 100 mum have a decreased medial thickness, lower cell nuclei density, and greater elastic fiber density when compared with arteries with external diameter <= 100 mum. Congenital diaphragmatic hernia promoted a significant decrease in medial thickness and an increase in cell nuclei density in artery walls with external diameter > 100 mum. Prenatal treatments with tracheal ligation or intra-amniotic administration of dexamethasone or surfactant prevented these changes. In arteries with external diameter <= 100 mum, congenital diaphragmatic hernia promoted a significant increase in medial thickness and in cell nuclei density and a decrease in elastic fiber density. The prenatal treatments with tracheal ligation or intra-amniotic administration of dexamethasone or surfactant prevented these changes, although no effect was observed in elastic fiber density in the congenital diaphragmatic hernia plus dexamethasone group. CONCLUSIONS: Congenital diaphragmatic hernia promoted different structural changes for large or small arteries. The prenatal intra-amniotic administration of dexamethasone or surfactant had positive effects on the lung structural changes promoted by congenital diaphragmatic hernia, and these effects were comparable to the changes induced by tracheal ligation.

Hypertension in employees of a University General Hospital

PURPOSE: To find out the prevalence of hypertension in employees of the Hospital and relate it to social demographic variables. METHODS: Blood pressure measurement was performed with a mercury sphygmomanometer, using an appropriate cuff size for arm circumference, weight, and height in a population sample of 864 individuals out of the 9,905 employees of a University General Hospital stratified by gender, age, and job position. RESULTS: Hypertension prevalence was 26% (62% of these reported being aware of their hypertension and 38% were unaware but had systolic/diastolic blood pressures of >140 and/or >90 mm Hg at the moment of the measurement). Of those who were aware of having hypertension, 51% were found to be hypertensive at the moment of the measurement. The prevalence was found to be 17%, 23%, and 29% (P <.05) in physicians, nursing staff, and "others", respectively. The univariate analysis showed a significant odds ratio for the male gender, age >50 years, work unit being the Institute of Radiology and the Administration Building, educational level 10 years, and body mass index >30 kg/m². The multivariate logistic regression model revealed a statistically significant association of hypertension with the following variables: gender, age, skin color, family income, and body mass index. CONCLUSIONS: Hypertension prevalence was high, mainly in those who were not physicians or members of the nursing staff. High-risk groups (obese, non-white, men, low family income) should be better advised of prevention and early diagnosis of hypertension by means of special programs.

The organizational culture of a Brazilian public hospital

The objective of this research was to analyze the organizational culture of a Brazilian public hospital. It is a descriptive study with quantitative approach of data, developed in a public hospital of São Paulo State, Brazil. The sample was composed by 52 nurses and 146 nursing technicians and auxiliaries. Data were collected from January to June 2011 using the Brazilian Instrument for Assessing Organizational Culture – IBACO. The analysis of the organizational values showed the existence of hierarchical rigidity and centralization of power within the institution, as well as individualism and competition, which hinders teamwork. The values concerning workers’ well-being, satisfaction and motivation were not highly valued. In regard to organizational practices, the promotion of interpersonal relationship, continuous education, and rewarding practices were not valued either. It becomes apparent that traditional models of work organization support work practices and determine the organizational culture of the hospital.


Supplemental nursing staff´s experiences at a Spanish hospital: Qualitative phenomenology research

The objective of this study was to describe the Supplemental Nursing Staff´s experiences at different hospital units. A qualitative phenomenological approach was conducted; a purposeful and theoretical sampling was implemented with supplemental nursing staff at Santa Barbara Hospital of Soria (Spain), to gain a more in-depth understanding of the Supplemental Nursing Staff ´s experience. Data were collected by in-depth interviews and through a field notebook. Data were analyzed using the Giorgi proposal. Twenty-one nurses with a mean age of 46 years were included. Three main topics emerged from the data analysis: building the first contact, carving out a niche and establishing interprofessional/interpersonal relationships. We conclude that the experience of hosting the supplemental nursing staff in changing clinical environments is conditioned by various factors. It is necessary for nurses and hospital managers to establish clear objectives with regard to the supplemental nursing staff´s role in the units.

Nursing staff sizing in the emergency room of a university hospital

OBJECTIVE To verify the adequacy of the professional nursing staff in the emergency room of a university hospital and to evaluate the association between categories of risk classification triage with the Fugulin Patient Classification System. METHOD The classification of patients admitted into the emergency room was performed for 30 consecutive days through the methodology proposed by Gaidzinski for calculating nursing requirements. RESULTS The calculation determines the need for three registered nurses and four non-registered nursing for each six hour shift. However, only one registered nurse and four non-registered nurse were available per shift. There was no correlation between triage risk classification and classification of care by the Fugulin Patient Classification System. CONCLUSION A deficit in professional staff was identified in the emergency room. The specificity of this unit made it difficult to measure. To find the best strategy to do so, further studies should be performed.

Cost of nursing turnover in a Teaching Hospital

Abstract OBJECTIVE To map the sub processes related to turnover of nursing staff and to investigate and measure the nursing turnover cost. METHOD This is a descriptive-exploratory study, classified as case study, conducted in a teaching hospital in the southeastern, Brazil, in the period from May to November 2013. The population was composed by the nursing staff, using Nursing Turnover Cost Calculation Methodology. RESULTS The total cost of turnover was R$314.605,62, and ranged from R$2.221,42 to R$3.073,23 per employee. The costs of pre-hire totaled R$101.004,60 (32,1%), and the hiring process consumed R$92.743,60 (91.8%) The costs of post-hire totaled R$213.601,02 (67,9%), for the sub process decreased productivity, R$199.982,40 (93.6%). CONCLUSION The study identified the importance of managing the cost of staff turnover and the financial impact of the cost of the employee termination, which represented three times the average salary of the nursing staff.

The cost of excessive postoperative use of antimicrobials: the context of a public hospital

OBJECTIVE: To evaluate the improper use of antimicrobials during the postoperative period and its economic impact.METHODS: We conducted a prospective cohort study by collecting data from medical records of 237 patients operated on between 01/11/08 and 31/12/08.RESULTS: from the 237 patients with the information collected, 217 (91.56%) received antimicrobials. During the postoperative period, 125 (57.7%) patients received more than two antimicrobials. On average, 1.7 ± 0.6 antimicrobials were prescribed to patients, the most commonly prescribed antibiotic being cephalothin, in 41.5% (154) of cases. The direct cost of antimicrobial therapy accounted for 63.78% of all drug therapy, this large percentage being attributed in part to the extended antimicrobial prophylaxis. In the case of clean operations, where there was a mean duration of 5.2 days of antibiotics, antimicrobials represented 44.3% of the total therapy cost.CONCLUSION: The data illustrate the impact of overuse of antimicrobials, with questionable indications, creating situations that compromise patient safety and increasing costs in the assessed hospital.

Resultados auditivos com o implante coclear multicanal em pacientes submetidos a cirurgia no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo

A surdez profunda é uma deficiência que afeta a personalidade, o relacionamento e todo o estilo de vida do paciente. Incapacita os indivíduos de escutarem sons ambientes como sirenes e alarmes que constituem alerta em situações da vida diária e não permite a modulação vocal, tornando a voz esteticamente ruim. A prótese auditiva convencional é eficiente no tratamento de grande parte das deficiências auditivas, porém existem pacientes que não conseguem obter discriminação de palavras e sentenças mesmo com uma prótese auditiva potente. O implante coclear é a alternativa atual para estes pacientes. OBJETIVO: Avaliar o resultado auditivo dos pacientes adultos implantados com o implante coclear multicanal pelo Grupo de Implante Coclear da Disciplina de Otorrinolaringologia da Faculdade de medicina da Universidade de São Paulo. FORMA DE ESTUDO: Estudo de série. CASUÍSTICA E MÉTODO: Foram selecionados 61 pacientes com surdez profunda bilateral que utilizam o implante coclear multicanal por pelo menos seis meses e estudados os resultados auditivos através de testes de reconhecimento de palavras e sentenças. RESULTADOS: O PTA médio obtido pelos pacientes foi 38.7 dB NPS. A média em reconhecimento de sentenças em formato aberto foi de 71.3%, vogais em 86.5%, monossílabos em 52.60% e consoante medial em 52.6%. A maioria dos pacientes está apta ao uso do telefone. CONCLUSÃO: A avaliação auditiva obtida seis meses após a primeira programação do implante demonstra que pacientes de língua portuguesa obtêm excelentes resultados em testes de reconhecimento de palavras e sentenças em apresentação aberta, readquirindo uma audição útil.

Hemorragia pós-operatória em 397 adenotonsilectomias realizadas nos Hospitais Geral de Pirajussara (HGP) e Hospital Estadual de Diadema (HED) / UNIFESP-EPM

As adenotonsilectomias são cirurgias freqüentes na especialidade de otorrinolaringologia, e sua principal indicação é a hipertrofia das tonsilas palatinas e faríngeas. Sua complicação mais comum é a hemorragia. Em nosso trabalho apresentamos a incidência de hemorragia pós-operatória das adenotonsilectomias realizadas no Hospital Geral de Pirajussara (HGP) e Hospital Estadual de Diadema (HED), objetivando a identificação das causas de sangramento. FORMA DE ESTUDO: Coorte transversal historica. MATERIAL E MÉTODO: Foram avaliados 397 pacientes submetidos a cirurgias de adenoidectomias, tonsilectomias palatinas e adenotonsilectomias. Estas últimas representaram 91,7% do total. A idade dos pacientes variou de 2 a 39 anos. Foi realizada triagem pré-operatória através de exames laboratoriais em todos os pacientes e os mesmos foram acompanhados em retornos semanais até o primeiro mês de pós-operatório. RESULTADOS: Foram realizadas nos dois hospitais (HGP e HED) 397 cirurgias, sendo 364 adenotonsilectomias (91,7%), 16 tonsilectomias palatinas (4,03%) e 17 adenoidectomias (4,28%). Houve 5 casos de sangramento no pós-operatório, sendo 3 no período imediato e 2 no período mediato. Não ocorreu nenhum caso de hemorragia no período tardio. A incidência de hemorragia, portanto, foi de 1,37% (5 casos em 364). CONCLUSÃO: a hemorragia pós-operatória parece estar relacionada com a dificuldade técnica da cirurgia e alterações da hemostasia encontradas em alguns pacientes.

Fratura de mandíbula: análise de 293 pacientes tratados no Hospital de Clínicas da Universidade Federal de Uberlândia

A fratura de mandíbula ocupa o segundo lugar entre as fraturas dos ossos da face, tendo havido aumento significativo de casos nos últimos anos. A não-identificação e o tratamento inadequado podem levar à deformidade estética ou funcional permanente. OBJETIVO: Avaliar os casos submetidos à redução de fratura de mandíbula no Hospital de Clínicas da Universidade Federal de Uberlândia, entre janeiro de 1974 e dezembro de 2002. FORMA DE ESTUDO: coorte historica. PACIENTES E MÉTODO: Duzentos e noventa e três pacientes foram submetidos à redução de fratura de mandíbula e retrospectivamente foram avaliados segundo fatores relacionados a: paciente, trauma, quadro clínico e tratamento cirúrgico. RESULTADOS: Houve uma clara tendência de aumento do número de fraturas de mandíbula ao longo dos anos. Houve um predomínio no sexo masculino (4:1), com pico de ocorrência entre 20 a 29 anos. As principais causas de fratura da mandíbula neste estudo foram acidentes de trânsito e violência, perfazendo juntas 72,4%. Cento e trinta e cinco pacientes apresentavam fratura única. Os sítios mais acometidos foram, em ordem decrescente, sínfise, côndilo, ângulo, corpo, ramo e processo coronóide. Foram realizadas redução incruenta (28), cruenta (213) e associação das duas (11 pacientes), sendo que 56,8% dos pacientes foram tratados nos primeiros 3 dias e 50,4% recebeu a alta hospitalar até o primeiro pós-operatório. Cerca de 10% dos pacientes apresentaram complicações, sendo osteomielite a mais freqüente. CONCLUSÃO: A incidência de fraturas de mandíbula foi marcadamente maior no sexo masculino, durante a terceira década de vida. A causa mais comum foi o acidente de trânsito e as regiões mais atingidas foram sínfise e côndilo. As fraturas isoladas de mandíbula ocorreram em mais de metade dos casos. A maioria dos pacientes foi tratada nos primeiros três dias e recebeu alta até o primeiro pós-operatório. A redução cruenta foi tratamento mais comumente empregado. A complicação mais freqüente foi a osteomielite.

Corpo estranho de orelha, nariz e orofaringe: experiência de um hospital terciário

A ocorrência de corpos estranhos em otorrinolaringologia é motivo de freqüentes consultas em serviços de emergência. OBJETIVO: Avaliar a incidência de pacientes com corpo estranho, bem como analisar o quadro clínico e o tratamento nestes casos. MÉTODO: Foi realizado estudo prospectivo de 81 pacientes com diagnóstico de corpo estranho de nariz, orelha ou orofaringe admitidos no Serviço de Otorrinolaringologia do Hospital do Servidor Público Municipal de São Paulo, no período de abril de 2003 a março de 2005. RESULTADOS: Foram 57 casos de corpo estranho de orelha; 13 de cavidade nasal; e 11 de orofaringe. Destes pacientes, 51,85% foram do sexo masculino e 48,15% do sexo feminino. A média de idade foi de 23 anos. A média do tempo de evolução foi de 18,36 dias, sendo que 38,27% dos casos foram atendidos com menos de 24 horas de evolução. Do total de pacientes, 83,95% receberam atendimento inicial na clínica de otorrinolaringologia, e 16,05% vieram encaminhados de outro serviço após alguma tentativa de remoção prévia. O sintoma mais comum dos casos de corpos estranhos de orofaringe foi a odinofagia presente em 90,91% dos casos; nos corpos estranhos de nariz, a rinorréia unilateral e cacosmia estiveram presentes em 46,15% dos casos; e nos corpos estranhos de orelha, 38,60% evoluíram sem sintomas, e 28,07% com hipoacusia. O corpo estranho mais freqüente de orofaringe foi a espinha de peixe (54,55%); no nariz foi o papel (30,77%); e na orelha foi o algodão (31,58%). As complicações decorrentes da presença de corpo estranho ou da manipulação dos mesmos foram encontradas em 13 casos (16,05%). CONCLUSÃO: A maioria dos casos com manipulação prévia para remoção de corpo estranho por profissional não-habilitado ou por leigo evoluiu com complicações, enfatizando que o manejo dos pacientes com corpo estranho deve ser realizado pelo médico otorrinolaringologista e com o uso de material adequado.

Ingestão acidental de moedas por crianças: atuação do Setor de Otorrinolaringologia do Hospital João XXIII

Os casos de introdução de corpos estranhos acidentais em crianças são freqüentes nos pronto-atendimentos. O otorrinolaringologista pode atuar nos casos localizados no esôfago. A experiência é fundamental para o sucesso das intervenções. OBJETIVO: Descrever o atendimento de crianças que ingeriram moedas no Setor de Otorrinolaringologia do Hospital João XXIII. FORMA DE ESTUDO: Clínico prospectivo. MATERIAL E MÉTODO: Foram avaliados sete casos de ingestão de moedas (idade, sexo, status na família, tamanho da moeda, conduta/evolução). RESULTADOS: A idade variou de um até nove anos. Dois pacientes eram filhos únicos e cinco eram mais novos. O tamanho da moeda variou de 1,9cm até 2,5cm. Após oito horas de observação, três casos necessitaram de remoção no centro cirúrgico porque a radiografia mostrava a moeda na cricofaringe e em quatro casos houve a descida espontaneamente para o intestino. CONCLUSÃO: O Setor de Otorrinolaringologia tem bons resultados usando laringoscópio de lâmina reta e pinça nos casos alojados na cricofaringe e esofagoscopia rígida para os casos distais. A amostra não permite concluir se o tamanho da moeda e a idade influenciam a descida espontânea para o trato gastrointestinal e se os pacientes filhos únicos ou os mais novos são mais predispostos a este acidente.
