    (MDPI, 2019-09-19) Guzman Aroca, Florentina; Garcia Ortega, Ana Azahara; Hernández Gómez, Dolores; Berná Mestre, Juan de Dios; Berná Serna, Juan De Dios; Dermatología, Estomatología, Radiología y Medicina Física
    The aim of this study was to investigate the efficacy of the vacuum-assisted biopsy (VAB) system in evacuating symptomatic haematomas after VAB excision of benign breast lesions. We retrospectively analysed the data of eight patients with symptomatic and large haematomas who were treated with VAB evacuation between 10 and 14 days after VAB excision. Only one case underwent the procedure 24 h after VAB excision, due to the patient reporting intense pain, which was relieved after application of the technique, even though it had to be done twice. This new clinical application of the VAB system for evacuating symptomatic breast haematomas was successful in all the cases in the present study. No technique-related complications were observed. Conclusions: To the best of our knowledge, this is the first study to reveal that VAB evacuation of symptomatic haematomas is safe, effective, quick and well-tolerated by patients.

    A new treatment for mammillary fistulas using ultrasound-guided percutaneous needle electrolysis
    (MDPI, 2020-02-28) García Vidal, José Antonio; Escolar Reina, María P.; Medina Mirapeix, Francesc; Guzmán Aroca, Florentina; Piñero Madrona, Antonio; Berná Mestre, Juan de Dios; Berná Serna, Juan De Dios; Fisioterapia
    The aim of this study was to investigate the efficacy of ultrasound-guided percutaneous needle electrolysis (PNE) in mammillary fistulas (MFs). A prospective study was performed in 18 patients with MF who were treated with the PNE technique. The technique was repeated in the case of no response or recurrence. The results obtained show that MFs revealing an elongated appearance with the ultrasound (US) are generally resolved with two sessions of PNE, whereas ovoid MFs require several sessions of PNE for complete resolution and they tend to recur. Success of the treatment with PNE was observed in 88.8% of the patients (16/18), and failure, after five or six sessions in two cases (11.2%), which were referred for surgery. Conclusions: To the best of our knowledge this is the first study to reveal that the PNE technique is safe, effective, quick, and well-tolerated by patients.

    Combining high-power ultrasound and enological enzymes during winemaking to improve the chromatic characteristics of red wine
    (Elsevier, 2021-12-28) Pérez Porras, Paula; Bautista Ortín, Ana Belén; Jurado, Ricardo; Gómez Plaza, Encarna; Tecnología de Alimentos, Nutrición y Bromatología; Facultad de Veterinaria
    Several techniques have been used by the winemaking industry to facilitate the extraction of grape phenolic compounds during the maceration process. Interest in innovative techniques such as high-power ultrasound (US) has increased in recent years, replacing more traditional techniques such as the addition of pectolytic enzymes (E). This study evaluates the combined effect of ultrasound and enological enzymes, used at semi-industrial scale at the time of crushing, on the chromatic characteristics of red wine. Variables such as the timing of enzyme addition and the ripening state of the grapes were considered. The results showed that ultrasound had a greater effect than enological enzymes when used alone, especially when the ripest grapes were used. The results also indicate that, when added after sonication, the enzymes favored the US effect, enabling the contact time necessary to achieve a wine with chromatic characteristics similar to those resulting from a traditional maceration process to be reduced by 4 days. Carried out on a semi-industrial scale, the study demonstrates that the adequate combination of these two techniques can optimize the maceration process both in terms of time and the wine organoleptic characteristics, making the technique of special interest for industrial application.

    (Wiley, 2011-09-01) Domenech, Ernesto; Bern Serna, Juan de Dios; Polo, Luis; Reus Pintado, Manuel; Berná Mestre, Juan de Dios; Canteras, Manuel; Dermatología, Estomatología, Radiología y Medicina Física
    Objectives: The purpose of this study was to evaluate the effect of intra-articular injection of SonoVue (sulfur hexafluoride with a phospholipid shell; Bracco SpA, Milan, Italy) on the synovial membrane in an animal model. Methods: Twenty-one New Zealand White rabbits (42 knees) were used in this study. We injected the knees with normal saline (saline group; n = 21) and SonoVue (SonoVue group; n = 21). A histologic examination of the knees was performed out at 3 and 12 hours and 3, 7, 15, 30, and 45 days after injection. Four histologic parameters (synovial hyperplasia, synovial stroma, vascular dilatation, and inflammatory infiltrates) were graded separately. Results: We found no significant differences in this study for synovial hyperplasia, vascular dilatation, or inflammatory infiltrates between the saline and SonoVue groups. A significant difference was only observed for synovial stroma (P < .05), and most of the histologic changes were mild in the saline group and moderate in the SonoVue group. The histologic changes observed in this study are considered transitory and reversible. Conclusions: The results suggest that intra-articular injection of SonoVue is a safe procedure.

    Effects of cervical myofascial trigger points release in post-natal females: A randomized controlled trial
    (Universidad de Murcia, Servicio de Publicaciones, 2021) Hasanin, Marwa Esmael; Mohamed, Rania Reda; Hamada, Hamada Ahmed; Hanafy, Abeer Farag
    The aim was to investigate and compare the effectiveness of Ultrasound (US) versus a combination of US and ischemic compression (IC) technique on headache pain intensity and range of motion (ROM) of the cervical region in healthy females with myofascial trigger points (MTrPs) in the cervical muscles, following normal delivery. Forty females (ages 20-35 years) with MTrPs in the muscles of the neck took part in the study.They were assigned into control group (US therapy for the MTrPs of the upper trapezius and sub-occipital muscles) and study group (IC technique on the active MTrPs of the muscles in addition to the US application). They received eight sessions for 4 weeks (2 sessions/week). All patients were evaluated before and after treatment for the intensity of radiating headache by Visual Analogue Scale (VAS) and the universal goniometer to measure cervical ROM. Two-way mixed design MANOVA demonstrated a significant decrease (p<0.05) in headache pain intensity and a significant increase (p<0.05) in neck flexion, extension, right and left side bending, and rotation in both groups when compared to pre-treatment circumstances. Additionally, there was a significant reduction in pain intensity after treatment in the study group compared to the control group (p<0.05). In conclusion,in healthy females after normal delivery, US alone or in combination with the IC technique is effective for releasing cervical myofascial trigger points and has positive effects on radiating headache and cervical ROM.In addition, IC technique was a complement to US in reducing the severity of headache pain, but its effect on improving cervical ROM was practically but not statistically significant.

    New insights into the pathophysiology of fasciculations in amyotrophic lateral sclerosis: an ultrasound study
    (Elsevier, 2018) Vázquez Costa, J. F.; Campins Romeu, M.; Martínez Payá, Jacinto Javier; Tembl, J. I.; Baño Aledo, María Elena del; Ríos Díaz, J.; Fornés Ferrer, V.; Chumillas, M. J.; Sevilla, T.; Fisioterapia
    Objective: To describe the fasciculation pattern in ALS and to analyse its clinical and pathophysiological significance. Methods: Ultrasound of 19 muscles was performed in 44 patients with a recent diagnosis (<90 days) of ALS. The numberof fasciculationswas recorded in each muscle and the muscle thickness and strengthwere additionally measured in limb muscles. A subgroup of patients were electromyographically assessed. Results: US was performed in 835 muscles and EMG was available in 263 muscles. US detected fasciculations more frequently than EMG. Fasciculations were widespread, especially in upper limbs onset patients and in the cervical region. Fasciculations’ number inversely associated with ALSFR-R and body mass index (BMI) and directly with BMI loss and upper motor neuron (UMN) impairment. Our statistical model suggest that fasciculations increasewith the initial lower motor neuron (LMN) degeneration, reach their peak when the muscle became mildly to moderately weak, decreasing afterwards with increasing muscle weakness and atrophy.

    Osteochondritis dissecans of the knee. Sonographically guided percutaneous drilling
    (Wiley, 2008-02-01) Martinez, Francisco; Reus Pintado, Manuel; Berná Mestre, Juan de Dios; Berná Serna, Juan De Dios; Dermatología, Estomatología, Radiología y Medicina Física
    Objective: The purpose of this study was to present a procedure for sonographically guided percutaneous drilling in the treatment of a case of osteochondritis dissecans (OD) of the knee. Methods: A 14-year-old boy had OD of the external femoral condyle. Conventional radiography, magnetic resonance imaging, and sonography revealed the osteochondral lesion. Results: This study showed the utility of sonography both in the treatment of OD through percutaneous drilling and in follow-up. Conclusions: On the basis of the good results obtained in the case described here, it is thought that sonographically guided percutaneous drilling may be a good alternative to arthroscopic drilling in cases of early OD lesions without displacement of the fragment.

    Rendimiento de OPU en vacas de raza murciano-levantina: respuesta a la estimulación ovárica mediante FSHp (Pluset®)
    (2025-04) Metony, Océane; Heras García, Sonia; Ramal Barea, Ismael; Ruiz López, Salvador; Romero Aguirregomezcorta, Jon; Departamentos; Universidad de Murcia, Servicio de publicaciones.; Facultades,Servicios y Escuelas::Facultades de la UMU::Facultad de Veterinaria
    La técnica OPU (Ovum Pick-Up) permite obtener ovocitos de animales vivos para la fecundación (FIV) y producción in vitro de embriones (PIV). El objetivo del trabajo ha sido evaluar el rendimiento de la OPU en vacas de raza Murciano-Levantina (M-L), con el fin de recuperar ovocitos para la preservación de esta raza en peligro de extinción. Se seleccionaron 2 vacas M-L, Madroña y Unicornio, de 13 y 6 años, respectivamente, que fueron someti-das a un protocolo de estimulación hormonal con FSHp (Pluset®) durante 4 semanas, con un total de 4 sesiones de OPU/animal. Los ovocitos recuperados fueron cuantificados y clasificados en 5 grados (I a IV y degenera-dos) según su calidad ovocitaria. Los ovocitos viables (grados I a III) fueron vitrificados o madurados in vitro para posterior FIV y PIV. Se obtuvieron un total de 108 ovocitos, 34,26% de Madroña y 65,74% de Unicornio, de los cuales 92 (85,18%) fueron viables. El número medio de ovocitos totales (p = 0,03) y viables (p = 0,02) fue superior en Unicornio comparado con Madroña. Se obtuvieron significativamente más ovocitos grados I (p = 0,04) y III (p = 0,03) de Unicornio que de Madroña, y no se encontraron diferencias significativas para ovocitos grado II, IV y degenerados. En Madroña, el mayor número de ovocitos obtenidos fue grado III, con diferencias significativas (p = 0,03) entre este grupo y ovocitos grado I, IV y degenerados. En Unicornio, el mayor número de ovocitos fue grado III, con diferencias significativas (p = 0,02; p = 0,03), entre éste y ovocitos grado IV y degenerados. Este estudio demuestra que la OPU puede aplicarse con éxito en vacas M-L. Los resultados obtenidos muestran que existe variabilidad entre donantes en el número y calidad de ovocitos recuperados. Resultaría conveniente optimizar los protocolos de conservación genética en esta raza.

    Sonographically guided percutaneous intralesional triamcinolone injection: a new treatment for mammillary fistulas. Preliminary results
    (Wiley, 2012-04-01) Berná Mestre, Juan de Dios; Piñero, Antonio; Carrascosa, Maria C.; Berná Serna, Juan De Dios; Dermatología, Estomatología, Radiología y Medicina Física
    We describe a new procedure, sonographically guided intralesional triamcinolone injection, for the treatment of mammillary fistulas. Six patients with mammillary fistulas were enrolled in this prospective study. Clinical improvement was rapid after the first triamcinolone injection. The initial response to treatment was assessed as complete in 4 cases, and the remaining 2 cases resolved successfully with additional injections. On the basis of the excellent results obtained in this study, it is thought that intralesional triamcinolone injection may be a good alternative to surgery.

    The generation of suspended cell wall material may limit the effect of ultrasound technology in some varietal wines
    (MDPI, 2024-04-24) Pérez Porras, Paula; Bautista Ortín, Ana Belén; Martínez-Lapuente, Leticia; Guadalupe, Zenaida; Ayestarán, Belén; Gómez Plaza, Encarna; Tecnología de Alimentos, Nutrición y Bromatología; Facultad de Veterinaria
    The disruptive effect exerted by high-power ultrasound on grape cell walls enhances phenolic extraction, improving chromatic characteristics during red wine maceration. However, short maceration times may, sometimes, hinder this enhancement, and this effect could be attributed to the suspended cell wall material formation facilitated by sonication. This suspended material, having a strong affinity for phenolic compounds, can lead to their precipitation and elimination during subsequent vinification stages and, consequently, a significant portion of extracted phenolic compounds may not contribute to the final phenolic composition of the wine, impacting its chromatic features. To demonstrate this effect, sonicated grapes of two different varieties were vinified with No modified process that eliminated part of this suspended material. Results confirm our hypothesis; that is, the lack of positive outcomes in some cases is due to phenolic compound adsorption on suspended material.

    Ultrasound therapy in rectus sheath hematoma
    (Oxford University Press, 2005-04-01) Sánchez Garre, Juan; Madrigal, Manuel; Zuazu, Isabel; Berná Mestre, Juan de Dios; Berná Serna, Juan De Dios; Dermatología, Estomatología, Radiología y Medicina Física
    Ultrasound (US) is one of the most common modalities used in intervention for musculoskeletal disorders, although its effectiveness is debated. The purpose of this case report is to describe the intervention, including the use of US, in the management of a large rectus sheath hematoma (RSH) in a patient receiving anticoagulant therapy. The patient was a 62-year-old woman with RSH who was receiving oral anticoagulant therapy and had a history of bouts of coughing. Computed tomographic scans verified the diagnosis of RSH. The report describes the patient examination, management, intervention, and outcomes. The intervention, including the use of US therapy, may have enabled a rapid resolution of the hematoma. This case report illustrates how US may be a useful modality for complementary management of RSH, helping the reabsorption of the hematoma.
