Background. Pathological vertebral fractures are rare and occur in inflammatory, tumor, and dystrophic lesions. Aim. This study aimed to analyze clinical features and morphological structure of pathological fractures of the spine in children. Materials and methods. The authors examined and operated 62 children aged 217 years for pathological vertebral fractures. We investigated the clinical, radiological, and morphological features. Results. The average age of children at the time of hospitalization was 10 years. Lesions of thoracic vertebrae prevailed (78%) with the maximum frequency of occurrence at the apex of physiological kyphosis Th78. In 10 cases, multiple lesions were noted, including the pathology of other parts of the skeleton. In 69% of observations, clinical symptoms were not dominated by mechanical back pain. Palpation pain (34%) and local spinal deformation (27%) were noted. On average, local kyphosis was 24. Eleven patients (18%) manifested a neurological deficiency, of which nine fractures were a consequence of the tumor process. In 16% of observations, the fracture of the vertebra was detected to be an accidental Х-ray finding. Among the radiation manifestations, all cases (12 patients) registered the decrease in the height of the vertebral body in the form of collapse. Destruction was manifested by various options other than blastic. Therapeutic and diagnostic interventions were performed in 56 patients, and in six children, manipulation was limited to trepan biopsy. The pathological fracture was caused by an inflammatory process in 50% of observations and tumors in 42%, of which 31% is malignant. Conclusions. Pathological spinal fracture in children should be considered as a syndrome, which in most cases is based on an inflammatory or tumor process. The high frequency of neoplastic, including malignant processes, requires active invasive diagnosis. Therapeutic tactics are determined by the clinical, radiation, and morphological characteristics of pathology.

Spinal injuries in children and adolescents are rare injuries, but consequences for the growing skeleton can be devastating. Knowledge of accident causes, clinical symptoms and diagnostics should be part of every trauma department treating the sepatients. We retrospectively analyzed patients with radiographically proven vertebral fractures of the spine. After clinical examination and tentative diagnosis the fractures and injuries were proven with conventional X-ray, computed tomography(CT) scans or magnetic resonance imaging (MRI). The study included 890 fractures in 546 patients with an average age of 12.8±6.2 (6.6-19.4) years. Females had anaverage age of 13.7±6.3 (7.4-20.0) years, whereas males were on average 12.0 (6.0-18.0) years old. Fall from height (58%) wasthe main cause of accident and the most common region of fracture was the thoracolumbar spine with a shift towards the thoracic spine the more fractures occurred. Merely 3.7% of all patients required operative treatment. If a vertebral fracture is found in children and adolescents, it is highly recommended to exclude synchronous additional spine fractures in other levels; prevention should concentrate on fall and traffic accidents.

Abstract Our study was conducted by consulting angioCT sites made on a CT GE LightSpeed VCT64 Slice CT and a CT GE LightSpeed 16 Slice CT, following the path and relationships of the descending thoracic aorta against the vertebral column, outside diameters thereof at the thoracic vertebrae T4, T7, T12 and posterior intercostal arteries characteristics. The origin of of the descending thoracic aorta we found most commonly on the left flank of the lower edge of the vertebral body T4, but I have encountered cases where it had come above the lower edge of T4 on level of intervertebral disc T4-T5 or even at the upper edge of T5 vertebral body. At thoracic vertebra T4, on a total of 30 cases, the descending thoracic aorta present a diameter of 20.0 to 32.6 mm, values that correspond to male gender and to females diameter ranging from 25.5 to 27, 4 mm. At level of T7 thoracic vertebra, thoracic aorta present a diameter of 19.6 to 29.5 mm, values found in men, in women the diameter being from 21.9 to 25.2 mm. At thoracic vertebra T12, on a total of 27 cases, the descending thoracic aorta present a diameter of 17.6 to 27.7 mm, in males the diameter was from 17.6 to 27.7 mm and females diameter ranging from 21.1 to 25.2. The length of the descending thoracic aorta was from 18.40 to 19.41 cm.

245 Background: Skeletal metastasis (SM) in advanced PDAC is an infrequent occurrence and has been previously reported to be < 2.5%. However; pathological fractures in these patients can result in intractable pain, immobilization and a significant deterioration in quality of life. Methods: A retrospective analysis was conducted of patients (pts) with advanced PDAC receiving palliative chemotherapy. Data collection included age, gender, ECOG, sites of disease, and overall survival (OS). Statistical analysis included Kaplan Meier survival analysis. Results: The 135 pts included had a median age of 65.8 years (range: 53.7–91.3); 5 (31.2%) were women and 11 (68.7%) had an ECOG performance status of 0 or 1. A majority of patients received combination therapy that was either gemcitabine or 5-flurouracil based. Sixteen pts (11.8%) had skeletal metastasis with the primary tumor located in the pancreatic body/tail (11 pts - 68.7%).The sites of SM included thoracic vertebrae (8), lumbar vertebrae (5), pelvis (5), ribs (4), sacrum (4), scapula (3), acetabulum (2), cervical vertebrae (2), femoral head (2), sternum (1) and humerus head (1). A majority of the lesions were osteolytic (62.5%) with a median time of diagnosis of SM from initial diagnosis being 1.25 months (range 0-33). Bone pain was observed as the initial symptom in 5 pts (32%), 1 pt (6.2%) had a pathological fracture. The mOS for patients with SM was 6.5 months (range 0-38) when compared to 8 months (range 0-147) without SM.The mOS for pts treated with gemcitabine based regimen was 5.75 months (range 2.5-14), and patients who received multiple lines of therapy including gemcitabine and 5-FU based regimens was 15 months (range 5-38). Survival from onset of skeletal metastases ranged from 0-14 months (mOS: 4 months). Conclusions: More effective systemic therapies which improve mOS are likely to result in increased incidence of SM. The most common sites observed were the thoracic and lumbar vertebrae and pathological fractures in these sites can be catastrophic. Therefore careful evaluation of skeletal signs and symptoms, early detection and intervention will be important to prevent morbidity and mortality from pathological fractures.

This is an experimental study of lung morphology in modeling sepsis on a background of severe purulent-inflammatory disease of soft tissues (necrotizing fasciitis) by original authors’ method. The study showed that early stages of sepsis (1-3 days) were characterized by manifestations of changes in lung tissue as vascular response, in the second period (the 7th day) by appearance and growth of non-obstructive microatelectases, whereas the third period (the 14th day) was characterized by progression of purulent-necrotic processes in soft tissues, development of surgical sepsis and acute respiratory distress syndrome. These changes in morphological structure of lung tissue are specific for generalized septic process and consequences of necrotizing fasciitis with its septic complication.

Abstract Cocoon is a kind of natural biopolymer material with reasonable structure and various functions. However, its structure and functions are often destroyed in practical application. In this study, we took common Bombyx Mori as the research object, and provided different cocooning sites for single or multiple silkworms to construct common stereoscopic cocoons (“normal cocoons” [NC]) and flat cocoons (“single-silkworm flat cocoons” [SFC] and “multi-silkworm flat cocoons” [MFC]), respectively, and compared the morphological structure and basic properties of these cocoons. The study found that the flat cocoons have similar multi-layered variable structure and characteristics compared to those of the common cocoons; also, morphological characteristics and physical and chemical properties of silk fiber from outer layer to inner layer, such as sericin content, fiber fineness, and change rule of basic mechanical properties, are completely consistent with those of the common cocoons. It can be considered that the flat cocoons are constructed by silkworms in the same “procedural” process as that of common cocoons. Due to the expansion of cocooning space, the mechanical properties of fibers are significantly improved. By controlling the size of the cocooning space or the quantity of silkworms cocooning simultaneously, and the time of spinning, a cocoon material with controllable thickness, weight per square meter, porosity, and number of cocoon layers can be obtained as a composite material for direct application.

Araceae is one type of plant that has a fairly high level of diversity and also rich in benefits such as a source of food, ornamental plants, and medicine. Research on the characteristics of Araceae in Indonesia is still limited. The purpose of this study was to identify Araceaeplants based on morphological structure and analyze the morphological characteristics ofAraceae in Liwa Botanical Garden, West Lampung. This research was conducted from November 2019 to January 2020. Data were collected at Liwa Botanical Garden, WestLampung based on exploration and observation collection methods. Morphological structure data were analyzed as descriptive and qualitative. The parts of plants that are compared between Araceae plants are the shape, size of leaves, petiole, and inflorescences. Observations show that 21 genera of Araceae are consisting of 26 plants. Araceae plants have three different ways of life, namely terrestrial, epiphytic, and aquatic. The shape of the leaves is ovatus, cordatus, lanceolatus, cuneatus, needle, peltatus, sagittatus, hastatus, palmatisect, bipinnatisect and tripinnatisect. The characteristics of this plant have compound interest with cob types (spadix) which are covered by a spatha with two types of inflorescences, namely unisexual and bisexual.

Abstract The morphological structure, size-age variability and dynamics of age-related fertility of producers of Baikal omul of pelagic, near-bottom and coastal morpho-ecological groups during the depressive state of the population were studied. There is an improvement in the indicators of the growth rate of fish, maturation and an increase in absolute individual fertility against the background of the dilution of the population and the release of the feeding area. A comparative characteristic of some morphological features of fish among morphological-ecological groups is given. The number of gill rakers on the first gill arch significantly distinguishes different morpho-ecological groups and ranges from 36 to 43 pieces for the near-bottom, from 40 to 46 pieces for the coastal and from 44 to 53 pieces for the pelagic morpho-ecological groups. It is noted that the spawning populations of the coastal and pelagic groups are mainly represented by young individuals. With age, the proportion of females increases in all groups. The largest indices of the pectoral, abdominal and anal fins, responsible for movement in the vertical plane, rotation and stop, are noted in the near-bottom group.
