Epidemiologia de les fractures perinatals a l'Hospital Germans Trias i Pujol. Relació entre el tipus de fractura de clavícula i la paràlisi braquial obstètrica.

Les fractures de clavícula perinatals són una complicació impredictible i inevitable dels nounats i un percentatge presentarà paràlisi braquial (PBO) que freqüentment s'autoresolt. S'estudien els factors de risc de la fractura i és el primer treball que estudia la relació entre el tipus de fractura clavicular i la presència de PBO al naixement i la permanència d'aquesta complicació. L'afectació del terç proximal de clavícula i la distòcia d'espatlles són factors de risc per al desenvolupament de la PBO inicial, però no el desplaçament de la fractura. La permanència de la complicació no s'ha relacionat amb cap factor de risc.

Fracturas de tercio medio clavícula tratamiento quirúrgico versus tratamiento ortopédico en pacientes jóvenes Hospital Kennedy 2006-2009

Introducción: el tratamiento usual para fracturas del tercio medio de la clavícula es el ortopédico, sin embargo recientemente se ha propuesto que el tratamiento quirúrgico podría ser una mejor opción para los pacientes jóvenes laboralmente activos afectados por este tipo de fractura. Métodos: este es un estudio retrospectivo analítico de corte transversal comprendido en un periodo de cuatro años (2006-2009) en el servicio de Ortopedia del Hospital Kennedy E.S.E. Los desenlaces que se evaluaron fueron la función del hombro, el reintegro laboral, lesión neurológica y alteración cosmética. Resultados: en total se evaluaron 204 pacientes, de los cuales solo 103 cumplieron con los criterios de inclusión (17 mujeres y 86 hombres), de los cuales 83 recibieron tratamiento ortopédico y 20 requirieron manejo quirúrgico con promedio de edades de 28.4 años manejados ortopédicamente y 30.4 años en tratamiento quirúrgico predominando el género masculino. Conclusión: para los pacientes con fractura de clavícula de tercio medio, sin importar el tipo de tratamiento al que fueron sometidos, el resultado desde el punto de vista funcional, lesión neurológica y reintegro laboral fueron similares con excepción de la alteración cosmética.

Fracturas del tercio medio de la clavícula en pacientes laboralmente activos tratamiento quirúrgico versus ortopédico

Introducción:. Para el tratamiento de pacientes con fractura del tercio medio de clavícula encontramos el ortopédico y quirúrgico, se desconoce a nivel local cuál alternativas ofrece un mejor desenlace. Materiales y Métodos: Estudio de cohorte retrospectiva, en pacientes con fractura del tercio medio de la clavícula comparando pacientes expuestos a tratamiento quirúrgico versus tratamiento ortopédico evaluando alteración estética, dolor, sesiones de fisioterapia, reintegro laboral y puntaje del DASH a los 3 meses de tratamiento. Resultados: 91 pacientes tratados ortopédicamente y 24 tratados quirúrgicamente. Mediana de edad 34.1 años para ambos tratamientos. El 20.2% de los pacientes sometidos al tratamiento quirúrgico presentaron dolor mientras que ningún paciente del grupo ortopédico presentó dolor después del tratamiento. El 79.1% de pacientes tratados ortopédicamente y el 20.9% tratados quirúrgicamente referían alteración estética. La medina de sesiones de fisioterapia realizadas para el tratamiento ortopédico fue 8.04 y 9.04 del quirúrgico. El promedio de reintegro laboral fue de 5 semanas para ambos tratamientos Discusión: Tanto el tratamiento ortopédico como el quirúrgico obtuvieron resultados muy similares para todas las variables medidas sin que se pueda concluir que uno sea mejor que el otro. Los pacientes con desplazamientos iniciales menores de 2 cm son candidatos para manejo ortopédico con buenos resultados con puntajes del DASH de 35 a los 3 meses tratamiento, los pacientes con desplazamientos iniciales mayores de 2 cm son los que con mayor frecuencia son sometidos a tratamientos quirúrgicos también encontrándose buenos resultados con puntajes del DASH de 38 a los 3 meses de tratamiento.

Acidentes na infância atendidos no pronto socorro de pediatria do Hospital das Clínicas de Botucatu que motivaram internação

Accidents represent a major public health problem as they are frequent, preventable, and account for high morbidity and mortality rates. Children are the most vulnerable to accidents due to their inherent characteristics, and as a result of their physical, sensorial, psychomotor and cognitive limitations, which will only develop with time. Watchfulness and careful attention are of paramount importance, especially as children develop locomotor skills that are accompanied by curiosity about their surroundings. Child accidents, particularly those that could have been avoided, are the accidents most commonly seen in emergency and urgency departments. Urgency and emergency departments are the greatest allies in the attention to pediatric accidents as they offer adequate, immediate and specific high complexity care to patients at risk, viewing their vital stabilization. Investigating the causes and consequences of this insult is essential to establish a diagnosis and to contribute for the adoption of measures of prevention, control, and assistance. To identify the epidemiologic characteristics of the accidents involving children that received care at the pediatric emergency department of Botucatu Medical School Hospital and required hospitalization. This quantitative, retrospective, descriptiveanalytic epidemiologic study included all children aged 0-14 years who had had an accident and were seen at the Pediatric Emergency Department of Botucatu Medical School Hospital of São Paulo State University/UNESP between January 1/2008 and December 31/2009. A total of 227 medical charts were reviewed and 178 (78.4%) patients were included in this study. Of these, 116 (65.1%) were males and 62 (34.8%) were females. Children aged 5 - 9 years (38.9%) were the most affected, followed by those aged 10 - 14 years (37.5%). Fractures occurred in 138 (77.5%) of the cases, followed by foreign bodies...

Minimal Invasive Ostheosintesis For Treatment Of Diaphiseal Transverse Humeral Shaft Fractures.

To evaluate patients with transverse fractures of the shaft of the humerus treated with indirect reduction and internal fixation with plate and screws through minimally invasive technique. Inclusion criteria were adult patients with transverse diaphyseal fractures of the humerus closed, isolated or not occurring within 15 days of the initial trauma. Exclusion criteria were patients with compound fractures. In two patients, proximal screw loosening occurred, however, the fractures consolidated in the same mean time as the rest of the series. Consolidation with up to 5 degrees of varus occurred in five cases and extension deficit was observed in the patient with olecranon fracture treated with tension band, which was not considered as a complication. There was no recurrence of infection or iatrogenic radial nerve injury. It can be concluded that minimally invasive osteosynthesis with bridge plate can be considered a safe and effective option for the treatment of transverse fractures of the humeral shaft. Level of Evidence III, Therapeutic Study.

Assessment Of The Fixation Of Mandibular Symphysis Fractures Using Conical Cannulated Screws: Mechanical And Photoelastic Tests.

The aim of this study was to use mechanical and photoelastic tests to compare the performance of cannulated screws with other fixation methods in mandibular symphysis fractures. Ten polyurethane mandibles were allocated to each group and fixed as follows: group PRP, 2 perpendicular miniplates; group PLL, 1 miniplate and 1 plate, parallel; and group CS, 2 cannulated screws. Vertical linear loading tests were performed. The differences between mean values were analyzed with the Tukey test. The photoelastic test was carried out using a polariscope. The results revealed differences between the CS and PRP groups at 1, 3, 5, and 10 millimeters of displacement. The photoelastic test confirmed higher stress concentration in all groups close to the mandibular base, whereas the CS group showed it throughout the region assessed. Conical cannulated screws performed well in mechanical and photoelastic tests.

Comparative In vitro Mechanical Evaluation Of Techniques Using A 2.0 mm Locking Fixation System For Simulated Fractures Of The Mandibular Body.

To perform a comparative evaluation of the mechanical resistance of simulated fractures of the mandibular body which were repaired using different fixation techniques with two different brands of 2.0 mm locking fixation systems. Four aluminum hemimandibles with linear sectioning simulating a mandibular body fracture were used as the substrates and were fixed using the two techniques and two different brands of fixation plate. These were divided into four groups: groups I and II were fixed with one four-hole plate, with four 6 mm screws in the tension zone and one four-hole plate, with four 10 mm screws in the compression zone; and groups III and IV were fixed with one four-hole plate with four 6 mm screws in the neutral zone. Fixation plates manufactured by Tóride were used for groups I and III, and by Traumec for groups II and IV. The hemimandibles were submitted to vertical, linear load testing in an Instron 4411 servohydraulic mechanical testing unit, and the load/displacement (3 mm, 5 mm and 7 mm) and the peak loads were measured. Means and standard deviations were evaluated applying variance analysis with a significance level of 5%. The only significant difference between the brands was seen at displacements of 7 mm. Comparing the techniques, groups I and II showed higher mechanical strength than groups III and IV, as expected. For the treatment of mandibular linear body fracture, two locking plates, one in the tension zone and another in the compression zone, have a greater mechanical strength than a single locking plate in the neutral zone.

Mechanical And Photoelastic Analysis Of Four Different Fixation Methods For Mandibular Body Fractures.

The aim of the present study was to compare four methods of fixation in mandibular body fractures. Mechanical and photoelastic tests were performed using polyurethane and photoelastic resin mandibles, respectively. The study groups contained the following: (I), two miniplates of 2.0 mm; (II) one 2.0 mm plate and an Erich arch bar; (III) one 2.4 mm plate and an Erich arch bar, and (IV) one 2.0 mm plate and one 2.4 mm plate. The differences between the mean values were analyzed using Tukey's test, the Mann-Whitney test and the Bonferroni correction. Group II recorded the lowest resistance, followed by groups I, IV and III. The photoelastic test confirmed the increase of tension in group II. The 2.4 mm system board in linear mandibular body fractures provided more resistance and the use of only one 2.0 mm plate in the central area of the mandible created higher tension.

Development Plates For Stable Internal Fixation: Study Of Mechanical Resistance In Simulated Fractures Of The Mandibular Condyle.

To develop Y-shaped plates with different thicknesses to be used in simulated fractures of the mandibular condyle. Ten plates were developed in Y shape, containing eight holes, and 30 synthetic polyurethane mandible replicas were developed for the study. The load test was performed on an Instron Model 4411 universal testing machine, applying load in the mediolateral and anterior-posterior positions on the head of the condyle. Two-way ANOVA with Tukey testing with a 5% significance level was used. It was observed that when the load was applied in the medial-lateral plate of greater thickness (1.5 mm), it gave the highest strength, while in the anteroposterior direction, the plate with the highest resistance was of the lesser thickness (0.6 mm). A plate with a thickness of 1.5 mm was the one with the highest average value for all displacements. In the anteroposterior direction, the highest values of resistance were seen in the displacement of 15 mm. After comparing the values of the biomechanical testing found in the scientific literature, it is suggested that the use of Y plates are suitable for use in subcondylar fractures within the limitations of the study.

Avaliação da consulta médica realizada por ingressantes na residência de Pediatria

Diversos autores relatam que a consulta médica se associa a melhores resultados quando se adota como referencial o modelo centrado no paciente. OBJETIVO: Avaliar se os médicos ingressantes na residência de Pediatria realizam consultas ambulatoriais segundo pressupostos do modelo centrado no paciente. MÉTODO: Em 2007, no início de seu estágio de ambulatório, dez residentes foram selecionados aleatoriamente para serem filmados durante a realização de uma consulta. Adotando-se como referencial teórico pressupostos do modelo centrado no paciente, os dados foram analisados por meio de metodologia qualitativa, por meio da técnica exploratória, com três juízes independentes. RESULTADOS: A maioria dos residentes explora precocemente a primeira queixa referida pelos pais, assumindo-a como principal; não explora outras queixas; decide e faz orientações terapêuticas de modo não compartilhado; conversa pouco com as crianças; cria longos momentos de silêncio durante a consulta; não explica o exame físico e às vezes utiliza o prontuário como a principal fonte de informação. CONCLUSÃO: Os residentes realizam consultas sem a inclusão da perspectiva dos pais e, portanto, não atendem segundo pressupostos do modelo centrado no paciente.

Ventilação oscilatória de alta freqüência em pediatria e neonatologia

Este trabalho teve por objetivo rever a literatura e descrever a utilização da ventilação oscilatória de alta freqüência em crianças e recém-nascidos. Revisão bibliográfica e seleção de publicações mais relevantes sobre ventilação de alta freqüência utilizando as bases de dados MedLine e SciElo publicadas nos últimos 15 anos. As seguintes palavras-chave foram utilizadas: ventilação oscilatória de alta freqüência, ventilação mecânica, síndrome do desconforto respiratório agudo, crianças e recém-nascidos. Descreveu-se o emprego da ventilação oscilatória de alta freqüência em crianças com síndrome do desconforto respiratório agudo, síndrome de escape de ar e doença pulmonar obstrutiva. Avaliou em recém-nascidos, síndrome do desconforto respiratório, displasia broncopulmonar, hemorragia peri-intraventricular, leucoencefalomalácia e extravasamento de ar. Também, abordou a transição da ventilação mecânica convencional para a ventilação de alta freqüência e o manuseio específico da ventilação de alta freqüência quanto à oxigenação, eliminação de gás carbônico, realização de exame radiológico, realização de sucção traqueal e utilização de sedação e bloqueio neuromuscular. Foram abordados o desmame deste modo ventilatório e as complicações. Em crianças maiores a ventilação oscilatória de alta freqüência é uma opção terapêutica, principalmente na síndrome do desconforto respiratório agudo, devendo ser empregada precocemente. Também pode ser útil em casos de síndrome de escape de ar e doença pulmonar obstrutiva. Em recém-nascidos, não há evidências que demonstram superioridade da ventilação oscilatória de alta freqüência em relação à ventilação convencional, sendo a síndrome de escape de ar a única situação clínica em que há evidência de melhores resultados com este modo ventilatório.

Nutrient intakes related to osteoporotic fractures in men and women - The Brazilian Osteoporosis Study (BRAZOS)

Background: Adequate nutrition plays an important role in bone mass accrual and maintenance and has been demonstrated as a significant tool for the prevention of fractures in individuals with osteoporosis. Objective: The aim of the present study was to evaluate bone health-related nutrients intake and its association with osteoporotic fractures in a representative sample of 2344 individuals aged 40 years or older in Brazil. Methods: In a transversal population-based study, a total of 2420 individuals over 40 years old were evaluated from March to April 2006. Participants were men and women from all socioeconomic classes and education levels living around the Brazilian territory Individuals responded a questionnaire including self reported fractures as well a 24-hour food recall. Nutrient intakes were evaluated by Nutrition Data System for Research software (NDSR, University of Minnesota, 2007). Low trauma fracture was defined as that resulting of a fall from standing height or less. Nutrient intakes adequacies were performed by using the DRI's proposed values. Statistical analysis comprises Oneway ANCOVA adjusted by age and use of nutritional supplements and multiple logistic regression. SAS software was used for statistical analysis. Results: Fractures was reported by 13% of men and 15% of women. Women with fractures presented significantly higher calcium, phosphorus and magnesium intakes. However, in all regions and socio-economical levels mean intakes of bone related nutrients were below the recommended levels. It was demonstrated that for every 100 mg/phosphorus increase the risk of fractures by 9% (OR 1.09; IC95% 1.05-1.13, p < 0.001). Conclusion: The results demonstrated inadequacies in bone related nutrients in our population as well that an increase in phosphorus intake is related to bone fractures.

The management of elderly patients with femoral fractures - A randomised controlled trial of early intervention versus standard care

Objective: To determine the effect of an early intervention program in an acute care setting on the length of stay in hospital of elderly patients with proximal femoral fractures. Setting: Acute orthopaedic ward of a large teaching hospital. Design and Participants: A randomised controlled trial comparing 38 intervention patients with 33 Standard Care patients. Intervention: Early surgery, minimal narcotic analgesia, intense daily therapy and close monitoring of patient needs via a multidisciplinary approach versus routine hospital management. Main outcome measures: Length of stay (LOS); deaths; level of independent functioning. Results: Mean LOS was shorter in the Intervention group than in the Standard Care group (21 days v. 32.5 days; P<0.01). After adjusting for other factors that could affect LOS (e.g. age, sex, pre-trauma functional levels, pre-trauma comorbidity and postsurgical complications), the Intervention program was significantly predictive of shorter LOS (P=0.01). The Intervention group did not experience greater numbers of deaths, deterioration in function or need for social support than the Standard Care group. Conclusion: This early intervention program in an acute care setting results in significantly shorter length of hospital stay for elderly patients with femoral fractures.

A Randomized Trial of Sodium Fluoride (60 mg) ± Estrogen in Postmenopausal Osteoporotic Vertebral Fractures

Postmenopausal Caucasian women aged less than 80 years (n = 99) with one or more atraumatic vertebral fracture and no hip fractures, were treated by cyclical administration of enteric coated sodium fluoride (NaF) or no NaF for 27 months, with precautions to prevent excessive stimulation of bone turnover. In the first study 65 women, unexposed to estrogen (-E study), age 70.8 +/- 0.8 years (mean SEM) were all treated with calcium (Ca) 1.0-1.2 g daily and ergocalciferol (D) 0.25 mg per 25 kg once weekly and were randomly assigned to cyclical NaF (6 months on. 3 months off, initial dose 60 mg/day; group F CaD, n = 34) or no NaF (group CaD, n = 3 1). In the second study 34 patients. age 65.5 +/- 1.2 years, on hormone replacement therapy (E) at baseline, had this standardized, and were all treated with Ca and D and similarly randomized (FE CaD, n = 17, E CaD, n = 17) (+E study). The patients were stratified according to E status and subsequently assigned randomly to NaF. Seventy-five patients completed the trial. Both groups treated with NaF showed an increase in lumbar spinal density (by DXA) above baseline by 27 months: FE CaD + 16.2% and F CaD +9.3% (both p = 0.0001). In neither group CaD nor E CaD did lumbar spinal density increase. Peripheral bone loss occurred at most sites in the F CaD group at 27 months: tibia/fibula shaft -7.3% (p = 0.005); femoral shaft -7.1% (p = 0.004); distal forearm -4.0% (p = 0.004); total hip -4.1% (p = 0. 003); and femoral neck -3.5% (p = 0.006). No significant loss occurred in group FE CaD. Differences between the two NaF groups were greatest at the total hip at 27 months but were not significant [p < 0.05; in view of the multiple bone mineral density (BMD) sites, an alpha of 0.01 was employed to denote significance in BMD changes throughout this paper]. Using Cox's proportional hazards model, in the -E study there were significantly more patients with first fresh vertebral fractures in those treated with NaF than in those not so treated (RR = 24.2, p = 0.008, 95% CI 2.3-255). Patients developing first fresh fractures in the first 9 months were markedly different between groups: -23% of F CaD, 0 of CaD, 29% of FE CaD and 0 of E CaD. The incidence of incomplete (stress) fractures was similar in the two NaF-treated groups. Complete nonvertebral fractures did not occur in the two +E groups, there were no differences between groups F CaD and CaD. Baseline BMD (spine and femoral neck) was related to incident vertebral fractures in the control groups (no NaF), but not in the two NaF groups. Our results and a literature review indicate that fluoride salts. if used, should be at low dosage, with pretreatment and co-treatment with a bone resorption inhibitor.

A randomized trial comparing hormone replacement therapy (HRT) and HRT plus calcitriol in the treatment of postmenopausal osteoporosis with vertebral fractures: Benefit of the combination on total body and hip density

We report a prospective, randomized, multi-center, open-label 2-year trial of 81 postmenopausal women aged 53-79 years with at least one minimal-trauma vertebral fracture (VF) and low (T-score below 2) lumbar bone mineral density (BMD). Group HRT received piperazine estrone sulfate (PES) 0.625 - 1.25 mg/d +/- medroxyprogesterone acetate (MPA) 2.5 - 5 mg/d,- group HRT/D received HRT plus calcitriol 0.25 mug bd. All with a baseline dietary calcium (Ca) of < I g/d received Ca carbonate 0.6 g nocte. Final data were on 66 - 70 patients. On HRT/D, significant (P < 0.001) BNID increases from baseline by DXA were at total body - head, trochanter, Ward's, total hip, inter-trochanter and femoral shaft (% group mean Delta 4.2, 6.1, 9.3. 3.7. 3.3 and 3.3%, respectively). On HRT, at these significant Deltas were restricted to the trochanter and sites. si Wards. Significant advantages of HRT/D over HRT were in BMD of total body (- head), total hip and trochanter (all P = 0.01). The differences in mean Delta at these sites were 1.3, 2.6 and 3.9%. At the following, both groups Improved significantly -lumbar spine (AP and lateral), forearm shaft and ultradistal tibia/fibula. The weightbearing, site - specific benefits of the combination associated with significant suppression of parathyroid hormone-suggest a beneficial effect on cortical bone. Suppression of bone turnover was significantly greater on HRT/D (serum osteocalcin P = 0.024 and urinary hydroxyproline/creatinine ratio P = 0.035). There was no significant difference in the number of patients who developed fresh VFs during the trial (HRT 8/36, 22%; HRT/D 4/34, 12% - intention to treat); likewise in the number who developed incident nonvertebral fractures. This Is the first study comparing the 2 treatments in a fracture population. The results indicate a significant benefit of calcitriol combined with HRT on total body BMD and on BNID at the hip, the major site of osteoporotic fracture.
