Analysis of Abstracts Presented at the Prosthodontic Research Section of IADR General Sessions 2004-2005: Demographics, Publication Rates, and Factors Contributing to Publication

Purpose: The purposes of this study were to describe the demographics of abstracts presented at the prosthodontics section of IADR General Sessions from 2004 to 2005, evaluate the publication rate of abstracts, and analyze the relationship between variables in abstracts and publication.Materials and Methods: Prosthodontics research section abstracts from the IADR General Session in 2004 and 2005 were evaluated for: number of authors, presentation type, origin, affiliation, topic, study design, statistics, study outcome, and funding. The publication rate was calculated following a PubMed search. The journal of publication, year of publication, and the length of time before publication were analyzed. Descriptive statistics were used for the data analysis; the relationships between presentation type, study design, study outcome, statistics, funding, and publication were analyzed using logistic regression (alpha = 0.05).Results: From 346 abstracts, 37.0% were published. For oral presentations, 40.7% were published; 35.8% of poster presentations were published. The mean duration before publicationwas 26.4months. North America had themost abstracts, and Europe had the most publications. Fixed prosthodontic research had the highest number and proportion for publication. A significant association with publication was noted for neutral study outcomes (p = 0.018), studies with funding (p = 0.035), and abstracts from Europe (p = 0.001).Conclusions: The majority of abstracts from the prosthodontics research section of IADR General Sessions from 2004 and 2005 remain unpublished. A significant association for publication was noted with neutral outcomes, funding, and abstracts from Europe.

Depression and Cognitive Decline: Factors Related to Demographics and Psycho Pharmacotherapy on Elderly in Nursing Homes

Objectives: To identify the prevalence of neuropsychiatric disorders, especially DP and CD, on a sample of nursing home residents, relating this prevalence with some aspects of the demographics and psycho pharmacotherapy. Methods: 48 elders from two different nursing homes were selected. The collection of demographic and pharmacological data was made utilizing medical records. The medication was classified according to the Anatomical Therapeutic Chemical Code (ATC) criteria. The Geriatric Depression Scale (GDS 30) and the Mini Mental State Examination (MMSE) tests were utilized to determine the prevalence of DP and CD. Results: It was observed in the sample a high incidence of DP and CD among the researched elders. More schooling individuals tend to present less CD. Individuals with less CD indicatives present less symptomatology for DP. Of all the researched elders, 54,2% are submitted to psycho pharmacotherapy. Of all the consumed medicine, 16,5% belonged to the class of neuropsychiatric medicine. The medicated elders present, in average, a larger symptomatology for DP (12 points/average/GDS) than the non-medicated elders (9,9 points/average/GDS). The inverse occurs in relation to the CD indicatives. The use of psychotropics, especially in association, can have negative effects related to depression and cognition. Discussion: The pharmacotherapy, characterized for the polymedication and chronicity, especially of neuropsychiatric medicines, deserves special attention among elders, because the data suggest a significant relation between the utilization of medicines, singly or in association, and the increase of CD and DP. In addition, the data suggest that DP is a risk factor for CD and DM.

Perioperative cardiac arrest and its mortality in children. A 9-year survey in a Brazilian tertiary teaching hospital

Background: the incidence of perioperative cardiac arrest and mortality in children is higher than in adults. This survey evaluated the incidence, causes, and outcome of perioperative cardiac arrests in a pediatric surgical population in a tertiary teaching hospital between 1996 and 2004.Methods: the incidence of cardiac arrest during anesthesia was identified from an anesthesia database. During the study period, 15 253 anesthetics were performed in children. Data collected included patient demographics, surgical procedures (elective, urgent, or emergency), ASA physical status classification, anesthesia provider information, type of surgery, surgical areas, and outcome. All cardiac arrests were reviewed and grouped by the cause of arrest and death into one of four groups: totally anesthesia-related, partially anesthesia-related, totally surgery-related, or totally child disease or condition-related.Results: There were 35 cardiac arrests (22.9 : 10 000) and 15 deaths (9.8 : 10 000). Major risk factors for cardiac arrest were neonates and children under 1 year of age (P < 0.05) with ASA III or poorer physical status (P < 0.05), in emergency surgery (P < 0.05), and general anesthesia (P < 0.05). Child disease/condition was the major cause of cardiac arrest or death (P < 0.05). There were seven cardiac arrests because of anesthesia (4.58 : 10 000) - four totally (2.62 : 10 000) and three partially related to anesthesia (1.96 : 10 000). There were no anesthesia attributable deaths reported. The main causes of anesthesia attributable cardiac arrest were respiratory events (71.5%) and medication-related events (28.5%).Conclusions: Perioperative cardiac arrests were relatively higher in neonates and infants than in older children with severe underlying disease and during emergency surgery. The fact that all anesthesia attributable cardiac arrests were related to airway management and medication administration is important in prevention strategies.

Eficácia do propofol e da associação de propofol e dexametasona no controle de náusea e vômito no pós-operatório de laparoscopia ginecológica

JUSTIFICATIVA E OBJETIVOS: A laparoscopia ginecológica é procedimento que determina alta incidência de náusea e vômito no pós-operatório. Este estudo teve por finalidade comparar a eficácia do propofol isoladamente ou em associação com a dexametasona na prevenção de náusea e vômito em pacientes submetidas à laparoscopia ginecológica. MÉTODO: Participaram do estudo 40 pacientes, estado físico ASA I e II, com idades entre 18 e 46 anos, sem queixas gástricas prévias, submetidas à laparoscopia para diagnóstico ou cirurgia. As pacientes foram divididas em 2 grupos: o grupo 1 recebeu (solução fisiológica 2 ml) e o grupo 2 dexametasona (8 mg), por via venosa antes da indução da anestesia. Todas as pacientes receberam midazolam (7,5 mg) por via oral como medicação pré-anestésica, sufentanil (0,5 µg.kg-1), propofol em infusão contínua para indução e manutenção da anestesia (BIS - 60) e N2O/O2 em fração inspirada de O2 a 40% e atracúrio (0,5 mg.kg-1) como bloqueador neuromuscular. A analgesia pós-operatória foi realizada com cetoprofeno (100 mg) e buscopam composto ®.As pacientes fora avaliadas na sala de recuperação pós-anestésica (SRPA) e na enfermaria 1, 2, 3 e 12 horas após a alta da SRPA. RESULTADOS: Ambos os grupos foram idênticos quanto aos dados antropométricos e à duração da cirurgia e da anestesia. No grupo 1 (n = 20) uma paciente apresentou náusea na SRPA e na enfermaria e três pacientes vomitaram na enfermaria. No grupo 2 (n = 20) nenhuma paciente apresentou náusea ou vômito durante o período de observação clínica, resultados estatisticamente não significativos. CONCLUSÕES: O propofol isoladamente ou associado à dexametasona foi eficaz na prevenção de náusea e vômito no pós-operatório de pacientes submetidas à laparoscopia ginecológica

CONCLUSÕES: O ondansetron e a alizaprida foram similares na prevenção de náusea e vômito em pacientes submetidas à laparoscopia ginecológica.

Efeitos da associação entre pequenas doses subaracnóideas de morfina e cetoprofeno venoso e oral em pacientes submetidas à cesariana

JUSTIFICATIVA E OBJETIVOS: Pequenas doses subaracnóideas de morfina são eficazes em reduzir a dor pós-operatória de pacientes submetidas à cesariana, com menor incidência de efeitos colaterais. O objetivo desta pesquisa foi avaliar a qualidade da analgesia pós-operatória e a ocorrência de efeitos colaterais em pacientes submetidas a cesarianas, sob anestesia subaracnóidea com bupivacaína hiperbárica e morfina nas doses de 0,05 mg e 0,1 mg, associadas ao cetoprofeno pelas vias venosa e oral. MÉTODO: Participaram do estudo 60 gestantes de termo, estado físico ASA I e II, que foram submetidas à cesariana eletiva. As pacientes foram divididas em dois grupos: grupo 1 - morfina 0,1 mg, grupo 2 - 0,05 mg, associada a 15 mg de bupivacaína hiperbárica. Todas receberam cetoprofeno (100 mg) por via venosa no per-operatório e por via oral a cada 8 horas no primeiro dia de pós-operatório. As pacientes foram avaliadas 6, 12 e 24 horas após o término da cirurgia, com relação à intensidade da dor e presença de efeitos colaterais (sedação, prurido, náusea e vômito). A presença destes últimos também foi avaliada no per-operatório. RESULTADOS: Ambos os grupos foram idênticos quanto aos dados antropométricos e à duração da cirurgia e da anestesia. Também foram homogêneos com relação à intensidade da dor pós-operatória e à presença de prurido, sedação, náusea e vômito. CONCLUSÕES: A morfina, nas doses de 0,05 mg e 0,1 mg administradas no espaço subaracnóideo, associada ao cetoprofeno pelas vias venosa e oral, apresentou a mesma qualidade de analgesia pós-operatória e determinou a mesma ocorrência de efeitos colaterais.

Quality of life and its association with cardiovascular risk factors in a community health care program population

OBJECTIVE: To evaluate quality of life in a population that attended a specific community event on health care education, and to investigate the association of their quality of life with the presence of cardiovascular risk factors INTRODUCTION: Interest in health-related quality of life is growing worldwide as a consequence of increasing rates of chronic disease. However, little is known about the association between quality of life and cardiovascular risk factors. METHODS: This study included 332 individuals. Demographics, blood pressure, body mass index, and casual glycemia were evaluated. The brief version of the World Health Organization Quality of Life questionnaire on quality of life was given to them. The medians of the scores obtained for the physical, psychological, emotional, and environmental domains were used as cutoffs to define higher and lower scores. A multinomial logistic regression model was used to define the parameters associated with lower scores. RESULTS: Diabetes mellitus, dyslipidemia, and obesity were associated with lower scores in the physical domain. Dyslipidemia was also associeted with lower scores in the psychological domain. Male gender and regular physical activity had protective effects on quality of life. Aging was inversely associated with decreased quality of life in the environmental domain. CONCLUSION: The presence of cardiovascular risk factors is related to a decreased quality of life. Conversely, male gender and regular physical activity had protective effects on quality of life. These findings suggest that exercising should be further promoted by health-related public programs, with a special focus on women.

Retrospective analysis of post-exposure to human anti-rabies treatment in Botucatu, São Paulo State, Brazil

This analysis aimed to identify characteristics of accidents that would, probably, provoke rabies infection. A total of 14,409 survey questionnaires for surveillance of human rabies from the Brazilian Information System for Disease Notification (SINAN), from 2000 to 2005, were analyzed. Regarding demographics, it was observed that 7,377 (51.5%) of the victims were white, 4,458 (30.93%) were children and 8,008 (55.58%) were males. Urban cases were prevalent (88.10%) while dogs were the animals most frequently involved in accidents, in 11,700 cases (81.19%). Bites (84.35%) and scratches (19.15%) were the most prevalent exposure types, and occurred predominantly on victims' extremities (38.79%). The prophylactic measure taken in 6,179 cases comprised anti-rabies vaccine; of these victims, 421 (2.92%) showed systemic reactions while 693 (4.80%) reported no response. The importance of developing awareness in professionals that should correctly report post-exposure immunoprophylaxis cases is emphasized given the high number of individuals who receive this type of treatment annually.

Geographical Distribution and Demographic Characteristics of Gestational Trophoblastic Disease

OBJECTIVE: To outline the geographical distribution pattern of gestational trophoblastic disease (GTD) in a referral center in Bahia, Brazil, and determine the demographics of the disease.STUDY DESIGN: We conducted a study of data retrieved from medical records of 140 GTD patients referred to our Trophoblastic Diseases Center in 2002-2007, assessing geographical distribution across health care districts, demographics, referral sources, and previous pregnancy status.RESULTS: The most common GTD types were hydatidiform mole (106, 75.7%), invasive mole (32, 22.9%), choriocarcinoma (1, 0.7%), and placental site trophoblastic tumor (1, 0.7%). GTD incidence was 8.5 in 1,000 deliveries. Most patients originated from the coastal region (East district), which includes the state capital (77.9%). The 20-34 age group predominated (65%). Education level (67.9% attended elementary school only) and employment rate (42.9%) were low. Secondary hospitals were the principal source of referral (84.3%), followed by self-referrals (15.7%). Regarding previous pregnancy status, 42.1% (n = 59) had had term pregnancy, 39.3% (n = 55) no pregnancy, 15% (n = 21) miscarriage, and 0.7% (n = 1) ectopic pregnancy; 4 patients (2.9%) had previous hydatidiform mole.CONCLUSION: GTD predominated in the peak fertility age group and among patients of unfavorable sociodemographic status.

Prevalência de sobrepeso/obesidade em crianças e adolescentes com constipação crônica funcional

OBJETIVO: Avaliar a prevalência do sobrepeso/obesidade em um grupo de crianças com constipação crônica funcional. MÉTODOS: Estudo retrospectivo com 257 crianças de dois a 15 anos com constipação crônica funcional diagnosticada segundo critérios de Roma II, atendidas consecutivamente em clínica terciária de gastroenterologia pediátrica. Informações demográficas, clínicas, diagnósticas e antropométricas foram obtidas de prontuários. O índice de massa corporal (IMC) foi calculado e utilizou-se a referência do Centers for Disease Control para determinar o percentil de IMC para idade e gênero. Crianças com percentil de IMC>85 foram consideradas com sobrepeso/obesidade; as com percentis > 5 e <85 foram classificadas como eutróficas. RESULTADOS: Para as variáveis sociodemográficas e clínicas, não houve diferença estatisticamente significante entre os subgrupos sobrepeso/obesidade e eutrofia. A prevalência de crianças constipadas com sobrepeso/obesidade foi de 24,4%. A média dos percentis do subgrupo sobrepeso/obesidade foi 94,4±4,3; a das eutróficas foi 45,3±24,2. A prevalência de sobrepeso/obesidade foi similar em ambos os sexos e grupos etários (<7 anos e >7 anos). CONCLUSÕES: Os subgrupos dos eutróficos e sobrepeso/obesidade foram homogêneos nas características sociodemográficas e clínicas, sugerindo que tais variáveis não influenciaram na prevalência do excesso de peso. A prevalência estimada de sobrepeso/obesidade entre as crianças com constipação crônica funcional está dentro dos valores esperados para a população pediátrica brasileira.

Immediate reconstruction of frontal sinus fractures: review of 26 cases

Purpose: the purpose of this study was to evaluate complications occurring after immediate reconstruction of severe frontal sinus fractures, including cases where the fracture was not limited to the anterior wall and also involved the posterior wall and/or sinus floor.Patients and Methods: the records of twenty-six patients presently undergoing follow-up for frontal sinus fracture reconstruction were reviewed. Information regarding demographics, fracture characteristics and causes, associated facial fractures, use of grafts or implants, type of fixation used, nasofrontal duct management, use of antibiotics, and complications were noted. Patients were asked to return for clinical and radiographic follow-up to access late complications.Results: the average age of patients with frontal fractures was 29.1 years and 92.3% were male. Mean follow-up was 3.6 years. The most common causes of fracture were motor vehicle accidents and physical aggression. All patients presented with comminuted and dislocated anterior wall fractures, 34.6% presented with posterior wall fractures, and 46% had sinus floor fractures. Complications occurred in 7 patients (26.92%) and included pneumoencephalus, frontal cutaneous fistula, frontal bone irregularity, and sinusitis.Conclusions: Frontal sinus reconstruction is a good procedure for immediate fracture treatment if there is not excessive comminution, dislocation, or instability of the posterior wall and if the frontonasal duct area is intact or can be repaired. Most complications result from incorrect indication for reconstruction. (C) 2004 American Association of Oral and Maxillofacial Surgeons.

Logistic regression analysis of potential prognostic factors for pulmonary thromboembolism

Objective: To identify potential prognostic factors for pulmonary thromboembolism (PTE), establishing a mathematical model to predict the risk for fatal PTE and nonfatal PTE.Method: the reports on 4,813 consecutive autopsies performed from 1979 to 1998 in a Brazilian tertiary referral medical school were reviewed for a retrospective study. From the medical records and autopsy reports of the 512 patients found with macroscopically and/or microscopically,documented PTE, data on demographics, underlying diseases, and probable PTE site of origin were gathered and studied by multiple logistic regression. Thereafter, the jackknife method, a statistical cross-validation technique that uses the original study patients to validate a clinical prediction rule, was performed.Results: the autopsy rate was 50.2%, and PTE prevalence was 10.6%. In 212 cases, PTE was the main cause of death (fatal PTE). The independent variables selected by the regression significance criteria that were more likely to be associated with fatal PTE were age (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.00 to 1.03), trauma (OR, 8.5; 95% CI, 2.20 to 32.81), right-sided cardiac thrombi (OR, 1.96; 95% CI, 1.02 to 3.77), pelvic vein thrombi (OR, 3.46; 95% CI, 1.19 to 10.05); those most likely to be associated with nonfatal PTE were systemic arterial hypertension (OR, 0.51; 95% CI, 0.33 to 0.80), pneumonia (OR, 0.46; 95% CI, 0.30 to 0.71), and sepsis (OR, 0.16; 95% CI, 0.06 to 0.40). The results obtained from the application of the equation in the 512 cases studied using logistic regression analysis suggest the range in which logit p > 0.336 favors the occurrence of fatal PTE, logit p < - 1.142 favors nonfatal PTE, and logit P with intermediate values is not conclusive. The cross-validation prediction misclassification rate was 25.6%, meaning that the prediction equation correctly classified the majority of the cases (74.4%).Conclusions: Although the usefulness of this method in everyday medical practice needs to be confirmed by a prospective study, for the time being our results suggest that concerning prevention, diagnosis, and treatment of PTE, strict attention should be given to those patients presenting the variables that are significant in the logistic regression model.
