Anomalies of the heart often expressed in severe functional cardiac abnormalities and sometimes life-threatening. Anomalies occurring to some extent a repetition of the stage of development of the structural features of the heart found in the phylogeny or embryogenesis.
Underdevelopment interatrial partitioning is expressed in the fact that the partition can not fold cover birth too large oval hole (Fig. 381). In addition to the foramen ovale may be an extra hole at the bottom interatrial septum.
Ventricular septal defect is more common in the membranous part of her, which is the place of the Read more [...]

The most common abnormalities found in derivatives branchial (aortic) arcs, although small arteries trunk and limbs often have diverse structure and topography of the various options. When you save the 4th right and left gill arches and roots dorsal aorta, the formation of aortic rings covering the esophagus and trachea. Observed anomaly development, in which the right subclavian artery departs from the aortic arch caudally than all other branches of the aortic arch.
Abnormal development of the aortic arch are expressed in the fact that the development is not left up to the 4th arc aorta and Read more [...]
Congenital umbilical hernia is reflected in the fact that the loops of the small intestine out through the extended umbilical opening of the abdominal cavity. In the region of the small intestine is formed Meckel's diverticulum, which is part of the yolk sac. Meets complete imperforate small intestine, or narrowing of the absence of any of its departments.
Volvulus is less common than the previous anomaly development, and is characterized by the fact that during the growth of intestinal loops and their rotation is observed abnormal twisting, preventing the passage of chyme.
Very rare anomaly Read more [...]

Frequent abnormality is the presence of an additional tool or fourth large molar. Quite common and no big third molars, which erupt as an afterthought only after 18 years. Sometimes wisdom teeth erupt after 30-40 years. If a wisdom tooth is not the second great root tooth too underdeveloped: it has three instead of four bumps and a small crown. In some cases, there is hypoplasia of the lateral incisors, second premolar teeth or complete lack thereof.
Some teeth are out of line of the alveolar process, and from the lingual or buccal alveolar arch, which is easily possible to correct orthopedic Read more [...]
Brown bear very cautious animal and mostly avoids meeting with the man. But the good-natured he only in fairy tales.

As already noted, eye develops from many beginnings, so there are various fetal malformations eyes.
Of the defects is the formation of irregular curvature of the cornea and lens - astigmatism, resulting in a projected image is not the point, and the lines. Due to improper formation of the eyeball can be congenital myopia (long eye) Or hyperopia (short eye) Without correcting refractive media of the eyeball and require wearing the appropriate glasses.
In congenital cataract may obstruct the passage of the light beam. As a result of underdevelopment of the venous sinus of the sclera and cornea Read more [...]
A person's sex is determined not by the external genitalia, and on the sex glands. Due to the fact that the external genitalia develop from genital tubercle, paired genital and urinary folds and independently of the internal genitalia, often abnormalities. True hermaphroditism (Androgyny) occurs when the developing testis and ovary. This anomaly very rare, and usually both glands are defective in structure and function. More common false androgyny (Fig. 347). A false female hermaphroditism ovaries are located in the labia lips that look like in this case, the scrotum. Hypertrophied Read more [...]

Anovulatory cycle (single cycle) - menstrual cycles without ovulation and formation of the corpus luteum, which are regular, often rhythmic, uterine bleeding.
Anovulatory cycles can occur in perfectly healthy women of child-bearing period. As a natural phenomenon they observed during lactation. If anovulatory cycles take systematic, this condition should be considered pathological, as it leads to infertility and in the future - to anovulatory bleeding.
Suspected anovulatory cycle can occur when a woman coming for infertility or to complain about the disorder of menstruation (more bleeding).

Hookworm - Helminthiasis caused by round worms - Ancylostoma. Distinguish hookworm, which is the causative agent of Ancylostoma duodenale, and necatoriasis, which is the causative agent of Necator americanus. Ankplostomid Size: 7-15 mm in the female, the male is 5-11 mm. At the head end of the body of worms has a gaping mouth capsule, surrounded with hookworms (Figure 1) with two pairs of hook-bent chitinous teeth, the American hookworm (Figure 2) - two cutting chitinous plates. Head end of the body in hookworms slightly bent to the ventral side, the American hookworm - sharply curved dorsally.

Ankylosing spondylitis - a serious disease, which starts mainly in youth and middle age, takes a progressive course, early lead to immobility (ankilozirovaniyu) ilio-sacral, and intervertebral edge-vertebral joints and the formation of so-called bamboo stick (spine over time become completely motionless). 8-10 years process involved hip and shoulder joints, which greatly reduces the efficiency of patients, patients become disabled and can not even take care of themselves.
Clinical foundations of the theory of ankylosing spondylitis and its characteristic features were developed in 1892 by VM Read more [...]
Movement in azimuth - undoubtedly the most important and versatile technique orientation. Azimuth move both short and long (several kilometers) distance. Movement in azimuth as a tactical option is available in a variety of situations, particularly if the card is badly adjusted, or are difficult to read. Even without knowing any other methods of guidance, you can achieve some success, going the distance in azimuth. But not limited to the azimuth.
Education movement in azimuth should begin with a practice session in the room, which explains the concept of the azimuth compass shows the correct Read more [...]
Cyclical flow of these two diseases roughly identical: their acute phase followed by a phase of remission. Rheumatoid arthritis and ankylosing spondylitis are prone to progression, high activity of inflammation in response to various natural healing methods tend to decline until complete remission. All this suggests that the two diseases common mechanism of development and at the same time there are significant differences in their clinical course. These differences are due primarily to the fact that the specific reaction Vaaler Rosa characteristic of rheumatoid arthritis, occurs in 75-80% of Read more [...]
9 years afterwards a squad of climbers including world-renowned alpinist Ballpark Young-Seok went wanting on Annapurna, searchers sustain no mind what may bear befallen the men.

The above facts indicate that the emergence of inflammatory process in some segments of the spine and pelvic ring is supported not only by local changes in cellular structures, but also the depletion of the adaptive function of body systems. Therefore it is necessary to bear in mind that if the early development of the inflammatory process can not use treatments that will improve the function of these systems, it is possible to slow down or even halt the progress of the disease. If the disease has taken a chronic course and had already come significant organic changes, to avoid further progression Read more [...]
Found that as the intensification course of inflammation increases levels of adrenaline and noradrenaline and decreasing rates of total, free and bound hydroxycorticosteroids in the blood, on the one hand (they define the flow conditions of inflammation), and increased erythrocyte sedimentation rate, increased levels of C-reactive protein, sialic acids, on the other hand (these parameters characterize the degree of destruction of collagen connective tissue).
With increased cell proliferation, disruption of water-salt metabolism and deposition of salts of lime, as well as with the development of Read more [...]
Ankylosis - Ankylosis, which occurs due to the formation of bone, cartilage, or fibrous union of the articular ends of bones articulate. Ankylosis may be caused by trauma (injury, closed comminuted fracture of the articular ends of bones, bruises and other injuries, especially repeated, accompanied by interstitial hemorrhage), infectious or degenerative process in the joint, as well as incorrect treatment of injuries and diseases of the joints, when not used functional treatment and is used long-term immobilization (see).
