Two-Portal Endoscopic Plantar Fascia Release: Step-by-Step Surgical Technique.

Plantar fasciitis is a common condition of heel pain with a lifetime incidence up to 10%. For this entity, conservative treatment is considered the gold standard, involving non-steroidal anti-inflammatory drugs, stretching exercises of the plantar fascia, activity modifications, ice, and insoles. When patients do not respond to these treatments, partial or total plantar fascia release has been the mainstay of treatment, with success rates of approximately 70% to 90%. For this purpose, several techniques have been described, including open, percutaneous, and endoscopic release. The objective of this Technical Note is to describe the nonassisted 2-portal endoscopic plantar fascia release in a patient with recalcitrant plantar fasciitis.

Retrograde Drilling With Tibial Autograft in Osteochondral Lesions of the Talar Dome.

Osteochondral lesions that compromise the ankle are rare, with an incidence between 0.02% and 1.5% according to different series. This location is the third in frequency, after knee and elbow. The location of the osteochondral lesion allows one to infer the producing mechanism. Lateral defects are produced by inversion and dorsiflexion of the ankle (usually anterior, affecting 3 and 6 talar zones), whereas medial defects are produced by plantar flexion, inversion, and internal rotation (most commonly posterior, affecting 4 and 7 talar zones). The injury causes pain associated with weight load, impaired function, limited range of motion, stiffness, blockage, and edema. Early diagnosis of an osteochondral lesion is particularly important because the lack of diagnosis can lead to the evolution of a small and stable lesion in a larger lesion or an unstable fragment, which can result in chronic pain, instability of the joint, and premature osteoarthritis. Multiple therapeutic strategies have been described, including conservative and surgical treatment. The purpose of this Technical Note is to describe arthroscopic-assisted retrograde drilling with tibial autograft procedure for osteochondral lesions of the talar dome.

Técnica DHS mínimamente invasiva: menor tiempo quirúrgico con similares resultados en el postoperatorio inmediato respecto al DHS convencional. Estudio retrospectivo de cohortes / Minimally invasive dynamic hip screw technique: Shorter surgical time with similar post-surgical results compared to conventional DHS technique. A retrospective cohort study

Objetivos. El tratamiento de fracturas pertrocantéreas con clavo DHS (Dynamic Hip Screw) mediante técnica mínimamente invasiva (MIDHS) ha mostrado resultados superiores a la técnica convencional (CDHS) en estudios previos. El presente estudio pretende determinar si existen diferencias en requerimientos transfusionales, morbilidad, estancia hospitalaria y en el coste asociado, a partir de un análisis retrospectivo de 2 cohortes. Material y método. Estudio de cohortes en 80 pacientes con fracturas intertrocantéreas de fémur (31-A1 y 31-A2.1) tratados con implante DHS entre julio de 2005 y septiembre de 2007: 40 de ellos con la técnica convencional y 40 de ellos con técnica MIDHS. Resultados. No se observaron diferencias estadísticamente significativas ni en la pérdida sanguínea, ni en requerimientos transfusionales, ni en morbilidad. La estancia hospitalaria en el grupo MIDHS fue 1,3 días menor, con un coste directo de 306,3 Euros por caso, inferior al grupo CDHS, aunque sin significación estadística (p = 0,3). La duración de la intervención fue menor en el grupo MIDHS: 49,3 versus 78,8 min (p = 0,0001). Discusión. Contrariamente a lo publicado en estudios previos, en el presente estudio la técnica MIDHS no ha mostrado ventajas excepto por requerir un menor tiempo para realizar la técnica. Consideramos que la técnica MIDHS podría ayudar en mejorar la productividad y eficiencia en el uso de quirófanos (AU)

Aim. The treatment of intertrochanteric fractures using a minimally invasive dynamic hip screw (MIDHS) technique has been reported to provide better results than the conventional technique (CDHS). The present study aims to determine whether there are any differences in terms of transfusion needs, morbidity, length of hospital stay, and economical costs, based on a study of two retrospective cohorts. Material and method. Cohorts study of 80 patients with intertrochanteric femoral fractures (31-A1 and 31-A2.1) who underwent DHS procedure from July 2005 to September 2007; 40 of them were treated using the traditional technique (CDHS), and the other 40 using the minimally invasive technique (MIDHS). Results. No differences were found in terms of blood loss, transfusion requirements or morbidity. Mean hospital stay for MIDHS group was 1.3 days lower, reducing the costs regarding the CDHS group by Euros 306.3, but this difference was not statistically significant (P =.3). The time required to perform the surgery was shorter for the MIDHS group: 49.3 versus 78.8 minutes (p = 0.0001). Discussion. Contrary to previous studies published, the present study did not show any advantage for the MIDHS technique, except for a shorter surgical time to perform the procedure. We consider that the MIDHS could help in improving operating room productivity and efficiency (AU)

Puente miocárdico como causa rara de sindrome coronario agudo sin elevación del ST / Myocardial bridge as a rare cause of acute coronary syndrome without ST elevation

Los puentes musculares están constituidos por haces de fibras musculares que recubren un trayecto variable de una arteria coronaria epicardica. Se relacionan generalmente con un buena sobrevida a largo plazo, cursando en muchos casos de forma asintomática como también causante de síndrome coronario isquémico agudo. Presentamos el caso de una paciente que ingresó al Departamento de Cardiología del Hospital Universitario de la Universidad Abierta Interamericana por dolor precordial típico con elevación de enzimas cardiacas y electrocardiograma normal. Dada la evolución de la paciente, se le realizó una prueba ergométrica que dio positiva para angor e injuria subendocardica anterior; y posterior cinecoronariografía que informó sobre la existencia de un puente muscular de importante magnitud en tercio medio de la arteria descendente anterior.

The muscular bridges are actually bundles of muscle fibers lining a path variable an epicardial usually relate to a good long-term survival; enrolled in many asymptomatic cases also cause acute ischemic coronary syndrome by a decrease variable caliber of the artery during the systolic compression. We report the case of a patient who was admitted to the Cardiology Department, Universidad Abierta Interamericana University Hospital by typical chest pain with elevated cardiac enzymes and normal electrocardiogram. Given the evolution of the patient underwent an exercise test that was positive for angina and subendocardial injury previous and subsequent coronary angiography that reported the existence of a significant amount of muscle bridge in the middle third of the left anterior descending artery.

[What do we know about atypical fractures in patients on biphosphonates treatment? A literature review using a case series]. / ¿Qué sabemos de las fracturas atípicas en los pacientes en tratamiento con bifosfonatos? Revisión bibliográfica a raíz de una serie de casos.

AIM: Retrospective review of long term biphosphonates treated patients who sustained a subtrochanteric or diaphyseal femoral fracture with an atypical pattern. A literature review is presented as an update of the topic. MATERIAL AND METHODS: A retrospective study was conducted on 13 subtrochanteric or diaphyseal fractures in female patients treated with biphosphonates at our institution from September 2007 to March 2011. RESULTS: Four cases of subtrochanteric fractures and 13 diaphyseal fractures were detected. Four patients had bilateral fractures. All cases but one (that affected only the lateral cortex) were complete fractures. Surgically, these kinds of fractures are demanding due to the hardness of the bones. DISCUSSION: It is difficult to know if there is any relationship between bisphosphonates treatment and atypical femoral fractures. Nevertheless, current literature supports a greater benefit of their use in preventing vertebral and non-vertebral fractures. For this reason, biphosphonates continue being considered as a first choice in the prevention of osteoporotic fractures. CONCLUSIONS: Patients on long-term treatment with bisphosphonates may present atypical femoral fractures as a complication. It is considered that the maximum period for biphosphonates treatment should not exceed 5 years.

Objetivos. Realizamos una revisión retrospectiva de los pacientes en tratamiento de forma prolongada con bifosfonatos que presentaron fracturas subtrocantéreas y diafisarias de fémur de patrón atípico. Revisión de la literatura existente con el fin de realizar una actualización del tema con consideraciones de interés para el cirujano ortopeda y traumatólogo. Material y métodos. Revisión de 13 pacientes en tratamiento con bifosfonatos con fracturas subtrocantéreas y diafisarias de fémur tratadas en nuestro centro entre septiembre de 2007 y marzo de 2011. Resultados. Se detectaron 4 casos de fracturas subtrocantéreas y 13 de fracturas diafisarias. Cuatro pacientes presentaron fracturas bilaterales. Todas las fracturas eran completas salvo un caso en el que era incompleta con afectación de la cortical lateral. La intervención quirúrgica fue más demandante técnicamente por encontrarse un hueso pétreo como consecuencia de la medicación con bifosfonatos. Discusión. Existe la dificultad de establecer la relación causal directa entre el tratamiento prolongado con bifosfonatos y las fracturas atípicas femorales. No obstante, la literatura actual refiere un beneficio superior en la prevención de fracturas vertebrales y no vertebrales y, por tanto, se continua considerando a los bifosfonatos como un fármaco de primera elección en la prevención de las fracturas osteoporóticas. Conclusiones. Los pacientes con tratamiento prolongado con bifosfonatos pueden presentar fracturas atípicas femorales como complicación. Se considera que debe evaluarse en un periodo medio menor a 5 años la sustitución parcial o definitiva por otro fármaco, teniendo en cuenta el riesgo residual de fractura estimado en ese momento (AU)

Applicability of confocal laser scanning microscopy for evaluation and monitoring of cutaneous wound healing.

There is a high demand for noninvasive imaging techniques for wound assessment. In vivo reflectance confocal laser scanning microscopy (CLSM) represents an innovative optical technique for noninvasive evaluation of normal and diseased skin in vivo at near cellular resolution. This study was designed to test the feasibility of CLSM for noninvasive analysis of cutaneous wound healing in 15 patients (7 male/8 female), including acute and chronic, superficial and deep dermal skin wounds. A commercially available CLSM system was used for the assessment of wound bed and wound margins in order to obtain descriptive cellular and morphological parameters of cutaneous wound repair noninvasively and over time. CLSM was able to visualize features of cutaneous wound repair in epidermal and superficial dermal wounds, including aspects of inflammation, neovascularisation, and tissue remodelling in vivo. Limitations include the lack of mechanic fixation of the optical system on moist surfaces restricting the analysis of chronic skin wounds to the wound margins, as well as a limited optical resolution in areas of significant slough formation. By describing CLSM features of cutaneous inflammation, vascularisation, and epithelialisation, the findings of this study support the role of CLSM in modern wound research and management.

Características nutricionales de una galleta formulada con plasma sanguíneo de bovino como principal fuente proteica / Nutritional characteristics of a cookie formulated with bovine blood plasma as a main source of protein

El objetivo de este trabajo fue evaluar las características nutricionales de una galleta formulada con plasma sanguíneo de bovino como fuente principal de proteína. Se preparó una mezcla con plasmas de bovino, harina de trigo, azúcar o sal, condimentos y aceite vegetal. La mezcla fue colocada en bandejas y horneada a 120 grados Celsius durante 1 hora. Al producto final se le determinó humedad, grasa, proteína, carbohidratos, contenido calórico, cenizas, hierro, aminoácidos esenciales, ácidos grasos esenciales, digestibilidad aparente, relación eficiencia proteica (PER), aceptabilidad y tolerancia. Los resultados indican que 100 g de la galleta contienen 5g de humedad, 16g de grasa, 16g de proteína, 61,4g de carbohidratos, 408,2 Kcal de energía metabolizable, 1,59g de cenizas, 1,9mg de hierro y 6,59g de aminoácidos esenciales. Los ácidos grasos poliinsaturados se encuentran en mayor proporción que los ácidos grasos saturados. Los resultados indican también que 100g de la galleta aportan por lo menos 20 por ciento de los requerimientos diarios de calorías, 24 por ciento de hierro y entre el 30 al 50 por ciento del requerimiento proteico diario en escolares. La digestibilidad y el PER, evaluados en ratas, fueron de 88,4 por ciento y 2,32 respectivamente. La aceptabilidad evaluada en niños fue de 97 por ciento y no se reportó intolerancia al producto en un período de seis meses de evaluación. La galleta pudiera ser incluida como complemento proteico y energético en los programas de merienda escolar.

[Nutritional characteristics of a cookie formulated with bovine blood plasma as a main source of protein]. / Características nutricionales de una galleta formulada con plasma sanguíneo de bovino como principal fuente proteica.

The nutritional characteristics of a cookie formulated with bovine plasma as main protein source was evaluated. Bovine plasma was mixed with wheat flour, sugar or salt, condiments and vegetable oil. The mix was placed in trays and baking at 120 degrees C during 1 hour. Moisture, fat, protein, carbohydrate, metabolizable energy, ash, iron, essential amino acids, essential fatty acids, apparent digestibility, protein efficiency ratio, acceptability and tolerance of the final product were determined. Results indicated that 100 g of the cookie have 5 g of moisture, 16 g of fat, 16 g of protein, 61.4 g of carbohydrate, 408.2 Kcal of metabolizable energy, 1.59 g of ash, 1.9 mg of iron and 6.59 g of essential amino acids. Polyunsaturated fatty acids are in higher amount than saturated fatty acids. Results also indicated that 100 g of cookie provide at least 20% of the daily energy requirements, 24% of the iron and between 30 to 50% of the daily protein requirements for children at school age. Its digestibility and PER, tested in rats, were of 88.4% and 2.32 respectively. Acceptability and tolerance, both tested in children, were 97% and 100% respectively. The protein cookie could be included as a protein and energy supply in school meals.
