Bacterial orbital cellulitis is a life-threatening infectious inflammation of the soft tissues behind the tarzorbital fascia.
Optico-chiasmal arachnoiditis, in essence, is an intracranial complication of an infection that penetrates to the basal brain envelopes that surrounds the visual crossover.
Neuritis of central origin also includes the disease of the optic nerve, called "optohohiasmal arachnoiditis."
Optical neuropathy is a serious complication, occurring in 5% of patients with endocrine ophthalmopathy. It develops due to compression of the optic nerve or vessels feeding it at the apex of the orbit with edematous and enlarged rectus muscles.
Inflammatory process in the optic nerve - neuritis - can develop both in its fibers and in the membranes. On the clinical course, two forms of optic neuritis are distinguished: intrabulbar and retrobulbar.
The oppositional disorder that causes the opposition is a recurrent or persistent negative, deviant or even hostile behavior directed against persons with power. Diagnosis is based on history data.
Opisthorchosis (Latin opisthorchiasis, French opisthorchiase) is a natural focal biogelmintosis with a fecal-oral mechanism of transmission of the pathogen, characterized by a prolonged course and a predominant lesion of the hepatobiliary system and pancreas.
Opisthorchiasis is a chronic helminthiasis with a primary lesion of the biliary system and the pancreas. In indigenous children of highly endemic foci, invasion usually occurs subclinically and is realized in mature or old age. In the area of endemia, visitors from non-endemic opisthorchiasis areas develop an acute stage of the disease of varying severity, followed by a transition to a chronic one.
Opisthorchiasis is a parasitic disease caused by hepatic trematodes that affect the hepatobiliary system and pancreas. It is characterized by polymorphism of clinical manifestations and chronic course.
The use of opioids for medical purposes, but without supervision by health workers and any use of non-medical indications, can lead to severe consequences with the development of addiction
Ophthalmoplegia - impaired mobility of the eye; can be determined by one or more reasons.
Herpes simplex virus type 1 (HSV-1) and varicella-zoster virus (VO-OG) remain the most relevant viral pathogens causing various damage to the visual organ. Traditionally, it is considered that ophthalmoherpes causes HSV-1.
There are two fundamentally different approaches to the surgical treatment of aneurysms: Traditional intracranial access with the discharge of the supporting arteries and the switching off of the aneurysm from the total blood flow by clipping its neck or forced occlusion of the aneurysm-bearing artery (trapping).
The arterial (botalla) duct is a necessary anatomical structure, providing together with the oval window and arantium duct the embryonic type of the fetal circulation. An open arterial duct is a vessel that connects the thoracic aorta to the pulmonary artery. Normally, the function of the arterial duct stops after a few hours (no more than 15-20) after birth, and the anatomical closure continues for 2-8 weeks.
The open trauma of the penis is often combined with traumas of other organs, including the organs of the genitourinary system. Open injuries of the penis in children often occur while playing with sharp objects or when falling on them.
Koloto-cut open lesions and traumas of the prostate and seminal vesicles occur in domestic, industrial or combat conditions when penetrating through the perineum or rectum of sharp piercing objects.
In the course of military operations, open lesions and injuries of the scrotum and testicle are more common. In modern combat conditions, they are found in 29.4% of the wounded with damage to the urogenital system.
Open injuries and bladder injuries in 24.1% are observed with gunshot wounds of the abdomen and 19.3% - damage to the urogenital organs.
According to the literature, open bite (mordex apertus) occurs in 1.7% of children, and more often in older age than in younger. This type of bite is 1-2% of the total number of its violations.
The share of the open atrioventricular canal accounts for about 4% of all congenital heart defects. The vice is characterized by underdevelopment of the partitions adjacent to the AV valves and the anomalies of the valves themselves.
