The most frequent complication of lung abscess

http://www.metapathia-hunter.com

Macroscopic basis of an early stage was a large cavity of destruction with insufficient spontaneous draining, indistinctly separated from surrounding lung tissue and filled with purulent exudate and sequesters. On Metapathia hunter image it was comparable with a large abscess of heterogeneous structure due to diffuse distribution of lesser achromogenic air signals against the background of prevailing moderately chromogenic content with coarse suspended matter and possible hypochromogenic sequesters. Irregular shape and uneven contours of a nidus, indistinct in spots inflammatory infiltration of surrounding lung were typical. Destruction cavity is limited by pulmobary tissue without chromogenic walls.
The most frequent complication of lung abscess was formation of bronchopleural fistula with development of empyema and pyopneumothorax, in certain cases accompanied by thoracic wall phlegmon and thoracal fistula. In one patient, who failed to find medical attention in time to treat an abscess of medium lobe of a right lung, we detected gigantic subdiaphragmatic abscess that developed as a result of cupula of diaphragm destruction with a background of pleural empyema.

The most favorable outcome of lung abscess is a complete collapse of a cavity with development of nidal fibrosis. As a stage of cicatrizing cavity an abscess looked like a small (less than 4 cm) parietal nidus with typical irregular or star-like shape, uneven serrate contour and heterogeneous structure because of short achromogenic air signals with prevailing hyperchromogenic background. At complete cicatrization of a cavity on its place we detected remaining small subpleural hypochromogenic area of irregular-shaped sclerosis, with uneven contours and significantly decreased or absent respiratory mobility. Less favorable outcome is formation of residual achromogenic air cavity similar to false cyst.

Bioplasm machine-research of urinary bladder

Full-scale Bioplasm machine-research of 365 patients (aged 26 – 83) with malignant tumoral affection of urinary bladder was performed in the Institute named after Gertsen P.A. 317 patients (86.8%) suffered from bladder cancer, 4 patients (1.1%) had sarcoma, 6 patients (1.6%) suffered from tumor deposits of another primary site, 2 patients (0.5%) had malignant non-Hodgkins lymphoma with bladder affection, 36 patients (9.9%) had tumor ingrowths into bladder wall from the adjacent organs. Male patients consisted the majority – 273 patients (74.8%) and 92 female patients (25.2%). All patients were examined using Bioplasm machine-research of urinary bladder. In all cases the microscanning of urinary bladder wall with spectral-entropy analysis of tissue structures was performed to provide differential diagnostics of various cancer types. All patients were operated on not later than 2 weeks after performance of NLS-research, the data of morphological research were compared with the result...

Three-dimensional Metatron hunter-graphy was carried with Metatron-4025 (IPP, Russia) system

http://www.metapathia-hunter.com At the first stage all patients were subjected to routine ultrasound examination of hepatobiliary system organs. Further on, in order to specify a nosological for of a disease, we used method of three-dimensional virtual Metatron hunter-reconstruction of an image and other hardware and laboratory researches (in accordance to medical and financial standards for this nosological type of a disease). Ultrasound examination was carried out with Acuson Sequoia 512 (Siemens, Germany) device, with multifrequency curvilinear transducer (2.5 – 6 MHz). Three-dimensional Metatron hunter-graphy was carried with Metatron-4025 (IPP, Russia) system with 4.9 GHz frequency generator and “Metapathia GR Clinical” software allowing to carry out three-dimensional virtual rendering of an object. Three-dimensional reconstruction was possible because of integrated into Metatron system specialized computer and mathematical program for Metatron hunter-information processi...

Possibilities of non-linear method in diagnostics of adrenals tumors

图片
http://www.metapathia-hunter.com Adrenals tumors are registered comparatively rarely, but it is know that they are most frequently hormone-active and even at small sizes lead to various endocrine disorders. However sometimes in clinical practice there are adrenals tumors without clinical symptoms and vague complaints of patients. References and our own experience show that period from appearance of the first symptoms till diagnosing varies from 6 months to 2 years.Early diagnostics of adrenals tumor has become an important clinical issue, which may be solved by application of non-linear diagnostics (NLS) along with CT, MRI and angiography. Today NLS-graphy is one of the most informative and prospective methods of diagnostics. Thanks to easiness of application, high informativity and safety NLS-graphy becoming a method of choice even at the first stage of hardware methods of diagnostics. NLS method of study allowed to increase significantly percentage of early and accu...
