RESUMO

INTRODUCTION: Patient satisfaction is the degree of conformity with the healthcare they receive. It is real evidence and one of the most important factors in determining the effectiveness and quality of healthcare systems. OBJECTIVE: To identify the quality of care in the Urology outpatient department of a third-level hospital. MATERIALS AND METHODS: The NHS (National Health Service) 2018 quality of care questionnaire with 11 sections, 133 items, and duration of approximately 25min was randomly administered to 250 patients attending Urology outpatients at a third-level public hospital in Mexico. RESULTS: According to responses, 92% (n=230) knew the reason for the consultation. 64.8% (n=162) had a consultation with the same physician by whom they were initially seen. The longest reported hospital wait time before being seen was more than 2h in 29.6% (n=74). As for consultation time, 212 patients responded and the duration was 11-20min in 52.8% (n=112). Finally, 33.2% (n=83) considered the quality of service to be good. CONCLUSIONS: The use of the NHS 2018 survey in the Urology service at a third-level public hospital in Mexico is feasible, since we managed to obtain a significant and continuous improvement in all its indicators which is satisfactory for all.

RESUMO

INTRODUCTION: in the treatment the long head of the biceps tendon (LHBT) pathology, the «relaxed tenodesis¼ is an arthroscopic articular suprapectoral tenodesis that seeks to lower the tension on the LHBT, and therefore, theoretically avoid persistent pain. OBJECTIVE: to assess clinical and radiological results of «relaxed¼ tenodesis in a prospective cohort of patient with work related illness. MATERIAL AND METHODS: prospective cohort, 54 shoulders with «relaxed¼ tenodesis performed with an intra-articular interference screw by the same surgeon, from October 2014 to 2018, in a level 1 trauma center. Demographic, clinical, functional and radiologic results were analyzed. On 6 months follow-up, a sonographic and clinical assessment was performed. RESULTS: mean age 49 ± 9, mean follow-up 16 ± 4 months. The main diagnosis was a rotator cuff tear in 79%, primary biceps pathology in 10% and other pathologies in 11%. At the end of follow-up, the cohort showed active anterior elevation 157.7 ± 22.7, external rotation 47 ± 16.6, median internal rotation T12, Constant Score 83 ± 12.05 points, subjective shoulder value 83 ± 12.97% and pain visual analogue scale 1.4 ± 1.7 points. One patient had a biceps tear and two had cosmetic arm asymmetry. On ultrasound 98% had the LHBT in situ and 10% had inflammatory changes on the bicipital groove. There were complications in 21% of the sample. CONCLUSIONS: «relaxed biceps tenodesis¼ is a technique that shows good clinical, functional and sonographic results, with low failure rate.


INTRODUCCIÓN: en el tratamiento de la patología del tendón de la cabeza larga del bíceps (TCLB) la tenodesis «relajada¼ es una tenodesis artroscópica suprapectoral alta, que busca disminuir la tensión del TCLB y, por tanto, el dolor persistente. OBJETIVO: evaluar resultados clínicos y radiológicos de la tenodesis «relajada¼ en una serie prospectiva de sujetos sometidos a compensación laboral. MATERIAL Y MÉTODOS: cohorte prospectiva de 54 hombros con tenodesis «relajada¼ con tornillo interferencial intraarticular, mismo cirujano, Octubre de 2014 a 2018, centro de trauma nivel 1. Se analizaron datos demográficos, resultados clínicos, funcionales y radiográficos. A los seis meses se realizó una ecografía de control y se evaluaron complicaciones. RESULTADOS: edad media 49 ± 9 años, seguimiento promedio 16 ± 4 meses. El diagnóstico primario fue rotura del manguito rotador en 79%, patología primaria del bíceps en 10% y otras patologías en 11%. Al término del seguimiento, la elevación anterior activa fue 157.7 ± 22.7, rotación externa 47 ± 16.6, rotación interna mediana T12, Constant Score 83 ± 12.05 puntos, valoración subjetiva del hombro 83 ± 12.97% y escala visual análoga del dolor 1.4 ± 1.7 puntos. Un paciente sufrió una rotura del bíceps y dos casos una asimetría estética del brazo. En ecografía, en 98% se visualizó el TCLB in situ y en 10% se objetivaron cambios inflamatorios en la corredera bicipital. Reportamos 21% de complicaciones. CONCLUSIONES: la tenodesis «relajada¼ presenta resultados clínicos, funcionales e imagenológicos satisfactorios, con baja tasa de fallo.

RESUMO

PURPOSE: Compare functional and radiological outcomes of three different designs of reverse shoulder arthroplasty according to distalization and lateralization shoulder angle, in heterogenic diagnostics (fracture, cuff arthropathy, fracture sequela and osteoarthritis). MATERIAL AND METHODS: Prospective cohort of 33 patients of reverse shoulder arthroplasty (RSA) between December 2014 and July 2017 with a minimum one year of follow-up. We defined three groups, G: 10 patients with Grammont (155o, Medialized Glena), B: 9 patients with Bio-RSA (155º, lateralized bone glena) and A: 14 patients with Arrow (135o, lateralized metallic glena). We analyze demographic, clinical, functional and radiological outcomes (lateralization shoulder angle (LSA) and distalization shoulder angle (DSA)). For the statistical analysis, ANOVA, T-tests and linear regression tests were used, with a statistical significance of 5%. RESULTS: The LSA was significantly higher in group A (98o A, 79o G, 80o B) (p < 0.05). In DSA, group B was significantly higher than A (52o B, 39o A) (p < 0.05) and not significant to G (48o G) (p = 0.06). There was no correlation of LSA and DSA with external rotation (p = 0.51) and active elevation (p = 0.41), respectively. There was no significant clinical (anterior elevation, external rotation, internal rotation) and functional outcomes (adjusted Constant score and subjective shoulder evaluation) differences between the different RSA models (p > 0.05). CONCLUSIONS: The LSA was higher in the Arrow and the DSA was higher in Bio-RSA. We did not find Clinical - Radiological correlation in this heterogeneous series of patients.


OBJETIVO: Comparar resultados funcionales e imagenológicos de tres modelos protésicos según el índice de lateralización y distalización. En un grupo heterogéneo de diagnósticos (fractura, artropatía de manguito, secuela de fractura y artrosis glenohumeral). MATERIAL Y MÉTODOS: Cohorte prospectiva de 33 pacientes sometidos a prótesis reversa de hombro entre Diciembre 2014 y Julio 2017 con un seguimiento mínimo de un año. Se definieron tres grupos, G: 10 pacientes con Grammont clásico (155o, Glena medializada); B: nueve pacientes con Bio-RSA (155o, glena lateralizada ósea); y A: 14 con Arrow (135o, glena lateralizada metálica). Las variables fueron: datos demográficos, clínicos, funcionales y radiológicos (ángulo de lateralización y distalización). Para el análisis estadístico se utilizaron pruebas de ANOVA, T-test y regresión lineal, con una significancia estadística de 5%. RESULTADOS: El ángulo de lateralización del hombro (LSA) fue significativamente mayor en el grupo A (98o A, 79o G, 80o B) (p < 0.05). El ángulo de distalización del hombro (DSA) del grupo B fue significativamente superior al A (52o B, 39o A) (p < 0.05) y no significativamente superior al G (48o G) (p = 0.06). No se demostró una correlación entre el LSA y DSA con la rotación externa (p = 0.51) y elevación activa (p = 0.41), respectivamente. En índices clínicos (elevación anterior, rotación externa, rotación interna) y funcionales (índice Constant ajustado y evaluación subjetiva de hombro) no encontramos diferencias significativas entre los distintos modelos protésicos (p > 0.05). CONCLUSIONES: El ángulo de lateralización fue mayor en el modelo Arrow y distalización en el modelo Bio-RSA. No encontramos correlación clínica-radiológica en esta serie heterogénea de pacientes.

RESUMO

OBJECTIVE: Anatomical risk factors predisposing to anterior cruciate ligament (ACL) and/or avulsion fractures of tibial spines (AFET) have been reported in paediatric patients with controversial results. Our aim is to compare morphometric parameters in magnetic resonance imaging (MRI) of patients with immature skeleton presenting AFET or ACL rupture versus healthy controls. METHODS: Observational study of a transverse cohort where all those patients with immature skeleton presenting ACL rupture or AFET were collected consecutively. A control group of patients with open physis and MRI reported without lesions was added. A trained observer measured in each MRI with previously standardized technique: a)the width of the intercondylar femoral notch, and b)the opening angle of the intercondylar femoral notch. RESULTS: The sample was composed of 11 patients with ACL rupture, 11 patients with TEA and 11 normal controls. The opening angle of the intercondylar femoral notch, measured in axial and coronal sections, was significantly lower in those patients with ACL rupture versus healthy controls (P=.0256 and P=.0097). The rest of the variables studied did not present significant differences between groups. CONCLUSION: In patients with an immature skeleton, a narrower femoral intercondylar notch is associated with ACL rupture, while those with an ETF do not present a distinctive bone anatomy versus healthy controls. These findings suggest that bone morphometric parameters are associated with a lesional or other pattern in open-knee.

RESUMO

Brachial plexus lesions can significantly affect patient function. The type of management will depend on the severity of the injury as well as the anatomical location. Tendon transfers around the shoulder have emerged as an effective treatment alternative, and therefore we should consider them when faced with patients who might require it. There are various transfer techniques, within which the most frequently used are upper trapezium, latissimus dorsi and lower trapezium transfers, each with its specific indications and objectives depending on the type of patient. These surgeries aim to decrease the pain resulting from the hypotonia and glenohumeral subluxation as well as improve the range of movement of the shoulder, getting the patient to take his hand to the plane that requires to perform his daily life activities. We will provide a description of some of the most commonly used shoulder tendon transfer techniques associated with a bibliographic review and a description of our experience with these surgeries.


Las lesiones de plexo braquial pueden afectar de forma muy significativa la función de los pacientes. El tipo de manejo va a depender de la severidad de la lesión como también de la localización anatómica de ésta. Las transferencias tendíneas alrededor del hombro han surgido como una alternativa efectiva de tratamiento y por lo tanto, debemos considerarlas cuando nos vemos enfrentados a pacientes que la podrían requerir. Existen diversas técnicas de transferencia, las que se utilizan con más frecuencia son las transferencias de trapecio superior, de dorsal ancho y de trapecio inferior, cada una con sus indicaciones y objetivos específicos según el tipo de paciente. Estas cirugías tienen como propósito disminuir el dolor producto de la hipotonía y subluxación glenohumeral como también mejorar el rango de movimiento del hombro, logrando que el paciente lleve su mano al plano que requiera para realizar sus actividades de la vida diaria. Presentaremos algunas de las técnicas de transferencia tendínea de hombro más utilizadas asociadas a una revisión bibliográfica y una descripción de nuestra experiencia con estas cirugías.

RESUMO

PURPOSE: More than half a million children experience non-accidental trauma (NAT) annually. Historically, NAT has been associated with an increased hospital length of stay (LOS). We hypothesized that in pediatric trauma patients, NAT is associated with longer hospital LOS, independent of injury severity, compared to accidental trauma (AT). METHODS: The Pediatric Trauma Quality Improvement Program (2014-2016) was queried for patients aged 1-16 years. Patients were stratified into two groups: AT and NAT. The median LOS for the entire cohort was identified and used in a multivariable logistic regression analysis. RESULTS: From 93,089 pediatric trauma patients, 417 (< 0.1%) were involved in NAT. Patients with NAT had a lower median age (3 vs. 9 years, p < 0.001) and higher median injury severity score (10 vs. 5, p < 0.001), compared to patients with AT. After controlling for covariates, patients with NAT were associated with a longer hospital LOS (≥ 2 days), compared to those with AT (OR = 4.99 CI = 3.55-7.01, p < 0.001). In comparison to AT, NAT was also associated with a higher mortality rate (10.3% vs. 0.8%, p < 0.001). CONCLUSION: Pediatric patients presenting after NAT have a prolonged hospital and ICU LOS, even after adjusting for injury severity. Furthermore, pediatric victims of NAT had a higher mortality rate compared to those presenting after AT.

RESUMO

La atresia gástrica es una rara entidad del tracto gastrointestinal. La clínica de vómitos no biliosos persistentes e intolerancia alimenticia obligan a descartar patología obstructiva alta. La prueba diagnóstica de elección es la radiografía simple abdominal con representación exclusiva de la cámara gástrica sin visualizar aireación distal. Presentamos a un recién nacido con sospecha clínica prenatal de obstrucción digestiva alta, confirmando atresia gástrica (AU)


Gastric atresia is a rare entity of gastrointestinal tract. The clinical features for persistent nonbilious vomiting and feeding intolerance require dismissing a proximal intestinal obstruction. The gold standard diagnosis test is an abdominal x-ray; it shows the single gastric bubble without any distal gas. We write about a newborn that suspect in prenatal studies an outlet bowel obstruction and confirm in the neonatal period a gastric atresia (AU)

RESUMO

El comportamiento del tercer molar después de la exodoncia del segundo molar, no ha sido muyreportada en la literatura y para muchos clínicos no es muy común. La extracción del segundo molar se debe realizar cuando el tercer molar se observa bien radiográficamente, con una adecuada vía de erupción y no debe exceder una inclinación de 30 grados con el plano oclusal, además debe encontrarse con un tercio de la raíz formada. Las indicaciones más frecuentes para la extraccióndel segundo molar son, segundo molar muy destruido, impactado o sobre-erupcionado, para luego distalizar el primer molar como se demuestra en los casos clínicos reportados. Es importante tener en cuenta la edad del paciente y condición periodontal, sobretodo en el arco inferior pues es más complejo el manejo del tercer molar luego de la exodoncia del segundo molar en dicho arco. Se debe monitorear el tercer molar hasta su adecuada ubicación en oclusión, porque puede requerir algún tipo de tratamiento adicional. En conclusión la exodoncia del segundo molar es una buenaalternativa a elegir cuando sea necesario pues con una correcta evaluación y tratamiento el tercer molar se ubica en una correcta posición.(AU)

RESUMO

La invaginación intestinal es una causa poco frecuente de dolor abdominal en adultos. Ocurre en menos del 1% de obstrucción intestinal de delgado. En adultos la mayoría de los casos son el resultado de una lesión intestinal; la invaginación idiopática es extremadamente rara. Presentamos un caso de obstrucción intestinal diagnosticado mediante tomografía computadorizada de invaginación de intestino delgado secundaria a un tumor. Se discute la etiología, diagnóstico y tratamiento de la invaginación intestinal del adulto (AU)


Intussusception is a rare cause of abdominal pain in adults. It occurs in less than 1% of all cases of adult small bowel obstruction. In adult population, most cases are the result of some type of intestinal lesion; idiopathic intussusceptions are an extremely rare occurrence in adults. This report describes one case of intestinal obstruction caused by an intussusception diagnosed by computed tomography(CT) scan. This report discusses the etiology, diagnosis, and treatment of adult intususcepción (AU)

RESUMO

BACKGROUND: The aim of this study was to determine the prevalence of E. coli O157:H7 in pediatric patients with acute gastroenteritis (AGE). PATIENTS AND METHODS: A prospective epidemiologic study was performed in cases and controls to detect the germ in fecal samples of 300 children with AGE in Bogotá, D.C. The stools of the patients and 85 controls were seeded in MacConkey-sorbitol agar. The sorbitol negative colonies were biotyped and seroagglutinated with a latex test for E. coli O157:H7. Antimicrobial susceptibility was performed after using the Bauer & Kirby method. RESULTS: Of the 300 diarrhea specimens analyzed, 14 strains corresponded to E. coli O157:H7 with a prevalence rate of 4.7% in children with AGE. The prevalence was 1.14%, the excess of risk of presenting E. coli O157:H7 was 14% in children with AGE. One child developed SUH. In three of the 85 controls E. coli O157:H7 was isolated, with a prevalence rate of 3.53%. The mean age of the 14 patients was 21 months (range: 3 months to 7 years) and the mean length of diarrhea in the children was 2 days. All the isolations of E. coli O157:H7 were sorbitol negative and indol negative with only 2 strains being MUG negative. DISCUSSION: This epidemiologic study has, for the first time, demonstrated the strong prevalence of E. coli O157:H7 in Colombia. The clinical data do not show a common pattern. Whether the strains isolated in the study are verotoxin producers remains to be demonstrated.
