[Retrolental amyloidosis of the vitreous body (case study)]. / Retrolental'nyi amiloidoz steklovidnogo tela (klinicheskoe nablyudenie).

Accumulations of pathological amyloid protein in the vitreous can be a pathognomonic morphological sign of systemic amyloidosis, which is characterized by deposition of insoluble fibrillar protein aggregates (amyloid) in various organs and tissues. The article describes a clinical case of a female 65-year-old patient with bilateral vitreous floaters and histologically confirmed vitreous amyloidosis on the right eye. The patient had undergone YAG laser vitreolysis of the right eye 3 years ago on the Ultra Q Reflex system («Ellex¼, Australia) to treat an atypical Weiss ring. Diagnosis of vitreous amyloidosis was confirmed using the following equipment: video slit lamp SL9900 («CSO¼, Italy), optical coherence tomography system Solix («Optovue¼, USA), B-scan Plus («Accutome¼, USA), microscope CX41RF («Olympus Corporation¼, Japan). Due to significant visual deterioration in the right eye, the patient underwent vitrectomy. Microscopic examination of the surgical sample showed the presence of amyloid deposits revealed by the brick-red specific staining with congo red dye and apple-green birefringence of the stained areas in polarized light.

[Clinical and morphological parallels in the validation of surgical treatment of nephrotuberculosi].

AIM: To Study clinical and morphological variants of kidney tuberculosis (KTB), for grounding a tactics of surgical treatment. MATERIALS AND METHODS: There were 107 examined patients (patients with cavitary lesions of kidneys: cavernous and multi-cavernous), operated in different phases of KTB. There were 56 men (52,3%) and women - 51(47,7%). The mean age of patients was 57,6 years (23-84 years). All the patients had a complex examination, including X-ray and ultrasound investigations, computer tomography ( was performed selectively), bacteriological examinations of urine and morphological examinations of removed kidneys or their parts. RESULTS AND DISCUSSION: Surgical interventions were as follows: open surgery nephrectomy 86/107 (80,4%), open organ-sparing surgery (resections of kidneys) 21/107 ( 19,6%). Mycobacterium tuberculosis were revealed by cultural method in 68,6% of cases in patients with cavernous KTB and in 76,3% of cases in patients with multi-cavernous KTB. In appliance with pathomorphological results of presented specimens, there were revealed 3 groups, each one with its own properties of cavern wall. I group (74 specimens) - stage of active progressing KTB, II group (20 specimens) - stage of intermediate activity, III group (13 specimens) - stage of healed caverns. Performed morphological investigations allowed us grounded a rational tactics of surgical treatment. It was defined that the longer specific anti-TB therapy was carried out the less frequency of TB progression we would have. However when it presented isolated cavitary lesion (isolated cavern), the performance of adequate and long courses of chemotherapy is not worth to do. Only surgical interventions (resection of infected tissue) with the anti-TB therapy allowed to reach the satisfactory results in treatment of KTB.

[Logical characteristics of specimens of the lung resected for tuberculosis].

The specimens of the lung resected for tuberculosis in 173 patients (10 with infiltrates, 133 with tuberculomas, and 30 with caverns) show its active forms with preponderance of decay, foci of dissemination, and a wide caseous and necrotic layer in the cavernous walls. Tissue responses reflect mainly immediate type hypersensitivity and they are followed by a slight development of epithelio-cellular granulomas.
