ethod for efficiency estimation of neoadjuvant polychemotherapy of malignant breast tumour // 2641158
FIELD: medicine.SUBSTANCE: invention refers to radio diagnostics, namely, ultrasound diagnostics, and can be used to evaluate the efficiency of neoadjuvant polychemotherapy (NAPCT) of malignant breast tumour. Tumour ultrasonography is carried out using a multifrequency linear sensor by scanning a breast tumour in the energy Doppler regime. Scanning is performed from points applied to the skin along 2 mutually perpendicular lines along the tumour boundary with 5-mm increment. Scanning is performed from each point in 2 mutually perpendicular planes. The quantitative processing of each of the obtained scans is carried out: the ratio of the number of coloured pixels and the total number of pixels is calculated for each scan. Then, the average value of the ratio for each plane and the average value of the ratio for both planes are calculated. The study is performed before and after the first course of NAPCT. With a decrease in the ratio value after the course of treatment by 32% or more compared to the value before treatment, the effect of NAPCT is estimated as positive. With a decrease in the ratio value by less than 32% or an increase in the ratio value, the absence of the effect of NAPCT is noted.EFFECT: method allows to accurately assess the effectiveness of neoadjuvant polychemotherapy by investigating the dynamics of malignant breast tumour blood supply.2 dwg, 3 ex

In this case, the search of a foreign body is carried out using a number of techniques: assessing the condition of the tissues adjacent to the wound to detect signs of metallosis, probing the tissues with the close Billroth's hemostatic forceps with visual control until the sensation of "scratching" appears, examining the wound with a finger, during which it is possible to feel the foreign body, creating an anti-support by the operator's arm in the circumference of the wound, which creates conditions for the palpation of the foreign body, or it's spontaneous exit into the wound and removal of the detected foreign body with a dissection forceps which ensures the exact capture of the sought object. Thanks to the control of the applied force, it's possible to avoid fragmentation of the foreign body, which ultimately minimizes the operational trauma and contributes to the successful removal of the sought object regardless of its localization.EFFECT: method allows to achieve the most accurate topical diagnosis of a foreign body in soft tissues by using non-invasive techniques and technically simple devices, successfully remove the foreign body, reduce the search time, minimize traumatization of tissues and avoide damage to anatomically important entities in the field of intervention.2 ex, 4 tbl, 20 dwg
