    The aim of this study was to determine the effect of ultrasound (US) on extra subserosal and intramural uterine fibroids in vitro. A quasi-experimental, randomized, pre-post intervention study of physical therapy was conducted. Thirty women, who underwent myomectomy for subserosal or intramural fibroids with any leiomyomas' volumes in the operating room of Bab El-Sharia Hospital, participated in the study. Thirty uterine fibroids whose were collected from participants were randomly divided into three groups (I, II and III), and exposed to ultrasound therapy for 15, 30, and 45 minutes respectively. Leiomyomas volumes were measured using the fluid displacement method before and after the application of US. The samples were kept in saline solution immediately after their excision from operating room to be transferred to physical therapy department in same hospital to apply ultrasound therapy. Results of all study groups (I, II, and III) showed a statistically significant decrease in the volume of subserosal and intramural leiomyoma post US application (p>0.05). However, there was no statistically significant difference in the size of the subserosal and intramural leiomyoma between study groups (p<0.05). In conclusion, the ultrasound therapy is effective in shrinking the volume of subserosal and intramural leiomyomas without effect of long duration ultrasound therapy.

    Interobserver agreement for thyroid elastography. Value of the quality factor
    (Wiley, 2013-03-01) Cepero Calvete, Angela; Rodriguez, José Manuel; Berná Mestre, Juan de Dios; Rios, Antonio; Abellán Rivero, Delores; Reus Pintado, Manuel; Dermatología, Estomatología, Radiología y Medicina Física
    Objectives—The purpose of our study was to investigate interobserver agreement for thyroid ultrasound elastography and to analyze the reproducibility of real-time free hand elastography in thyroid nodules. Methods—A prospective nonrandomized double-blind study was conducted between September 2008 and June 2010. Real-time elastography of 89 thyroid nodules was performed by two radiologists, with the first radiologist evaluating each thyroid nodule 5 minutes before the second. The elastograms were obtained with the patients holding their breath and considered valid when the quality factor was 50 or higher. The region of interest was positioned to include the nodule and 0.5 cm of surrounding normal thyroid parenchyma but to exclude the carotids and esophageal-tracheal structures. The elastograms were classified on a scale of 5 different patterns. Results—Observers 1 and 2 coincided in 79 elastographic patterns and disagreed on 10 nodules (11.2%). The results between the radiologists had a statistically significant agreement (P < .005), with a κ value of 0.838. Conclusions—The introduction of a quality factor in elastographic software and the selection of elastograms with a quality factor of 50 or higher confer almost perfect interobserver agreement for thyroid nodule elastography and make elastography a reproducible technique that could be used in daily clinical practice.

    Percutaneous management of breast abscesses. An experience of 39 cases
    (Elsevier Science Ltd., 2004-01-01) Madrigal, Manuel; Berná Mestre, Juan de Dios; Berná Serna, Juan De Dios; Dermatología, Estomatología, Radiología y Medicina Física
    This is a review of our experience with percutaneous drainage by means of needle aspiration or catheter drainage of breast abscesses under ultrasound (US) guidance, and a suggested management algorithm. A retrospective study of the 39 patients (36 women, 3 men; mean age: 28.9 years) with breast abscesses who were treated by percutaneous US-guided procedures over a period of 13 years (1989 to 2002) was carried out. Of the 36 women, 34 were nonlactating and two lactating. Needle aspiration was used in the cases of fluid collections < 3 cm and catheter drainage in fluid collections of > 3 cm. Postdrainage care and US evolutive controls were carried out on an outpatient basis. Fine-needle aspiration cytology was performed in masses unresolved after postdrainage. Mammography was performed in patients over 30 years old. In all cases, US examination revealed images of fluid collection. A single needle aspiration was sufficient in 19 cases; 3 patients needed a second aspiration to resolve the breast abscess. A total of 15 cases were resolved by means of percutaneous catheter drainage. In 2 of the 17 patients who underwent catheter drainage, the mass persisted postdrainage; histologic findings showed a chronic abscess requiring surgical intervention in one and a breast carcinoma in the second. Mean follow-up was 8.4 months. Recurrence of breast abscess occurred in 4 patients, and these were resolved by surgical excision. Percutaneous drainage procedures in breast abscesses are a safe and effective alternative to incision and drainage. Needle aspiration is employed in cases of small abscesses and catheter drainage in abscesses larger than 3 cm. Although, in chronic abscesses, the treatment of choice is surgical excision, percutaneous drainage remains as an intermediate therapeutic option.
