RESUMO

Many surgical techniques have been used to address unstable distal third clavicle fractures. Complications and the need for hardware removal are still a concern. We propose a surgical technical using high-strength sutures to restore vertical and horizontal stability in Neer type II and Neer type V distal-third clavicle fractures. It has been used in three cases; two type V and one type II. In all cases, bone healing was achieved uneventfully and all patients resumed their pre-injury activities including sports at sixmonths postoperatively. The coraco-clavicular loop and tension band suture technique is a simple procedure that allows vertical and horizontal stabilization of the fracture. It achieves good clinical results and it may be a costeffective alternative to other techniques although a longer series and longterm followup is required to adequately assess the results.


Se han descrito diferentes técnicas quirúrgicas para el tratamiento de las fracturas inestables del tercio distal de la clavícula. Las complicaciones asociadas y la necesidad de retirar los implantes siguen siendo motivo de preocupación. Proponemos una técnica quirúrgica que utiliza suturas de alta resistencia para restaurar la estabilidad vertical y horizontal en las fracturas del tercio distal de la clavícula de tipo II y V de la clasificación de Neer. Esta técnica se ha utilizado en tres casos; dos de tipo V y uno de tipo II. En todos se obtuvo la consolidación ósea y todos reanudaron sus actividades previas a la lesión, incluyendo actividad deportiva, a los seis meses de la cirugía. La técnica de cerclaje coracoclavicular y banda de tensión con sutura es un procedimiento sencillo que permite la estabilización vertical y horizontal de la fractura. Permite obtener buenos resultados clínicos y puede ser una alternativa coste-efectiva eficaz en el tratamiento de estas lesiones aunque se requiere una serie más larga y un seguimiento a largo plazo para evaluar adecuadamente los resultados.

RESUMO

Resumen: Introducción: Los resultados funcionales de las prótesis de superficie en el húmero proximal son aceptables, pero con grandes diferencias en la tasa y causa de revisión según las diferentes series. El objetivo de nuestro trabajo fue analizar los resultados clínicos obtenidos en nuestro centro y tratar de definir al paciente ideal para este implante. Material y métodos: Estudio retrospectivo de 19 casos. Seguimiento de 31 (12-61) meses. La cirugía se indicó en casos de artrosis primaria o secundaria. Se analizaron datos demográficos, escala de Constant normalizada, cuestionario DASH, complicaciones y satisfacción. Hubo tres pérdidas durante el seguimiento por fallecimiento sin relación con la cirugía. Resultados: Edad media de 56 (25-80) años. La puntuación en la escala de Constant normalizada fue 73 (23-104) puntos y en el cuestionario DASH 31 (7-84) puntos. Noventa y cuatro por ciento de los pacientes retomaron sus actividades de ocio. En siete casos se objetivó radiológicamente colocación en varo del implante generando un conflicto inferior en la glena. Se produjo una capsulitis adhesiva resuelta de forma conservadora, tres reintervenciones por usura glenoidea sintomática y una por dolor incontrolable. Los pacientes sin lesión del manguito rotador presentaron mejor puntuación en los cuestionarios funcionales. Todos los pacientes refirieron estar satisfechos con la mejoría sintomática respecto a la situación previa. Conclusiones: Los resultados funcionales obtenidos son similares a los publicados previamente. Creemos que la prótesis de superficie debe ser considerada una opción en los casos de artrosis primaria o secundaria sin lesión del manguito rotador, independientemente de la edad.


Abstract: Introduction: Data published in the literature about humeral resurfacing prostheses are not conclusive with good functional results but with large differences in the revision rate. The aim of our study was to evaluate the clinical and functional outcomes in patients operated at our center. Material and methods: Retrospective study of 19 cases in 18 patients. Follow-up of 31 (12-61) months. Surgery was indicated in cases of primary or secondary osteoarthritis. Demographic data, Constant scale, DASH questionnaire, complications and satisfaction were analyzed. Three patients were lost to follow-up due to death unrelated to surgery. Results: Mean age of 56 (25-80) years. Constant normalized of 73 (23-104) points. DASH questionnaire of 31 (7-84) points. Ninety four percent of the patients resumed their recreational activities and 81% sports activities. In seven cases, inferior conflict in the glenoid with varus implant was observed radiologically. There were five complications; a conservatively resolved capsulitis, three reinterventions due to symptomatic inferior glenoid usury and another to uncontrollable pain in a conservative way. Patients without rotator cuff lesion presented better scores on the functional questionnaires. All patients were satisfied with the symptomatic improvement over the previous situation and would be operated again if necessary. Conclusions: The functional outcomes reported are similar to those previously published and, based on them, we believe that the resurfacing prosthesis is an option to be considered in cases of primary or secondary osteoarthritis when there is no rotator cuff injury, regardless of age.

RESUMO

Introducción: una luxación bilateral es poco común y está poco descrita en la literatura. Caso clínico: presentamos un caso de luxación bilateral posterior del codo con fracturas asociadas de las apófisis coronoides (tipo I), en un paciente que cayó desde un metro de altura con los codos en extensión. Se efectuó la inmediata reducción cerrada bajo sedación con control radiográfico e inmovilización con férula posterior de los miembros superiores durante una semana. Durante el seguimiento se realizó una liberación del mismo con epitroclectomía a los 11 meses del traumatismo. En la revisión final presentó buena movilidad de ambos codos. Conclusiones: la luxación bilateral requiere un protocolo de actuación, reducción temprana, inmovilización con férula posterior durante 1-3 semanas y rehabilitación para evitar la rigidez e inestabilidad (AU)


Introduction: Bilateral dislocation is uncommon and is poorly described in the literature. Case report: We report a case of bilateral posterior elbow dislocation with associated fractures of coronoid apophysis (type I) in a patient falling from one-meter height with the elbows in extension. Immediate close reduction was performed under sedation with radiographic control and immobilisation with posterior splint of the upper extremities for one week. During the follow-up it was released with epitroclectomy at 11 months of the injury. Both elbows evidenced good mobility in the final revision. Conclusions: Bilateral dislocation requires an action protocol, early reduction, immobilisation with posterior splint for 1-3 weeks, and rehabilitation for preventing rigidity and instability (AU)

RESUMO

In this study, a combined approach is proposed to extend the shelf life of a composite pastry product (cannoli). In particular, to delay moisture migration, one, two, or three layers of a zein-based coating were studied. A three-layer coating represented the most effective solution to prevent rapid pastry softening. A subsequent experimental trial was aimed to prolong the shelf life of the ricotta-based stuffing. To this aim, two different antimicrobial compounds (lysozyme and lemon extract) at three concentrations (2,000, 3,000, and 4,000 ppm) were investigated separately from a microbiological and a sensorial point of view. Lemon extract was the active compound that received a better score, thus suggesting using 2,000 ppm of citrus extract in the last step. In the final experimental trial, cannoli were coated with three layers of zein, stuffed with ricotta containing the selected active agent, and packaged in two microperforated films. The use of zein-based coating and the lemon extract in the ricotta stuffing, combined with the barrier properties of the selected packaging materials, allowed a significant prolongation of cannoli shelf life, regardless of the type of film: a shelf life of more than 3 days was recorded, compared with the control samples, which were acceptable for less than 2 days. It is reasonable to assume that the proposed integrated approach could boost the distribution of the investigated typical pastry beyond local borders.

RESUMO

The aim of our study was to evaluate the antihypertensive effectiveness of verapamil slow-release (SR), administered once a day. We studied 11 patients, 7 male and 4 female, with an average age of 53.6 +/- 12.86 years, who had essential hypertension. After a drug washout period of at least 15 days, placebo was administered (one tablet per day), and then patients received verapamil SR 240 mg/day at 8:00 a.m. for at least 2 weeks. At the end of the washout, placebo, and active drug treatment periods we performed ambulatory intermittent blood pressure monitoring for 24 h using a Squibb Spacelabs pressurometer. After verapamil treatment, in comparison to placebo, a significant reduction of systolic (SBP) and diastolic blood pressure (DBP) (154.91 +/- 13.34/94.29 +/- 9.48 vs. 143.73 +/- 11.39/84.6 +/- 7.99 mm Hg; p less than 0.005), was observed without significant changes of the circadian blood pressure pattern. Moreover, we observed a significant reduction of SBP and DBP variability mainly during daytime, whereas this behavior was not evident for heart rate. In conclusion, verapamil SR seems useful to obtain a constant and significant reduction of 24-h blood pressure values with a significant reduction of SBP and DBP variability.
