Occupational intoxication occurs in upstream and downstream industries in people who come into contact with crude oil or its distillation products.
The pathogenesis of oil poisoning is divided into microbial (toxic infections, toxicoses, mixed etiology) and non-microbial. In the first case, pathogenic microorganisms multiply and release toxins, the accumulation of which in the body leads to general toxic syndrome.
An odontogenic cyst is a dental disease that occurs due to complications of periodontitis. Let's look at the main causes of this disease, diagnostic methods, treatment methods and prevention.
Ocular ischemic syndrome is a rare condition resulting from secondary hypoperfusion of the eyeball in response to acute ipsilateral atherosclerotic stenosis of the carotid arteries.
Occupational dermatoses account for up to 80% of occupational pathologies and arise as a result of the harmful effects of various production factors.
Occupational cancer is defined as a blastomogenic reaction that occurs as a result of a person’s professional activity with regular, usually long-term, contact with certain exogenous chemical and physical agents that act quite intensively.
Occupational asthma is a reversible airway obstruction that develops after months or years of sensitization to an allergen that a person encounters in the workplace. Symptoms of occupational asthma include shortness of breath, wheezing, coughing, and sometimes allergic symptoms of the upper respiratory tract.
Various branches of the aorta may become occluded due to atherosclerosis, fibromuscular dysplasia, or other conditions, resulting in symptoms of ischemia or infarction.
Low transverse position of the head occurs during childbirth in cases where the head, located with the occiput, moves towards the exit from the pelvis without making an internal rotation and remaining a sagittal suture in the transverse dimension.
Depending on where the back and back of the head are facing - forward to the symphysis or backward to the promontory - there are two types of high upright standing: anterior, positio occipitalis pubica s. anterior, and posterior, positio occipitalis sacralis s. posterior.
Obstructive sleep apnea (sleep apnea) involves episodes of partial and/or complete closure of the upper airway during sleep, resulting in cessation of breathing lasting more than 10 seconds. Symptoms of obstructive sleep apnea include fatigue, snoring, repeated awakenings, morning headache, and excessive daytime sleepiness. Diagnosis is based on sleep history, physical examination, and polysomnography.
Obstructive bronchitis is one of the types of complex, extensive inflammatory process of the bronchi, occurring with complex symptoms. Children of early and preschool age are predisposed to the acute form of obstructive bronchitis. Obstructive bronchitis in adults often manifests itself in exacerbations of its already chronic form.
Early obstetric peritonitis occurs on the 1st-3rd day after surgery. It is usually caused by infection during surgery, which was performed against the background of chorioamnionitis.
In case of pathological labor, untimely and incorrect obstetric care, birth injuries often occur: damage to the external and internal genital organs, as well as adjacent organs - the urinary tract, rectum, pelvic joints.
Obstetric hemorrhages are bleedings in the second half of pregnancy, during and after childbirth. Early postpartum hemorrhages are bleedings that occur in the first 2 hours, late hemorrhages are bleedings that occur more than 2 hours after childbirth.
According to DSM-IV, obsessive-compulsive disorder is a variant of anxiety disorder characterized by obsessive repetition of unwanted, unpleasant thoughts, images or impulses (obsessions) and/or repetitive actions that a person performs compulsively and according to certain rules (compulsions).
Obsessive-compulsive disorder is characterized by obsessions, compulsions, or both. Obsessions and compulsions cause significant distress and interfere with academic and social functioning. Diagnosis is based on history. Treatment includes behavioral therapy and SSRIs.
We have all, to a greater or lesser extent, found ourselves fixated on some thoughts or actions that seemed important to us at the moment, causing anxiety or irritation.
Thromboangiitis obliterans is an inflammatory thrombosis of small arteries, medium-sized arteries and some superficial veins, causing arterial ischemia of the distal extremities and superficial thrombophlebitis.
This group of diseases is based on atherosclerosis of the arteries of the lower extremities, causing ischemia. Moderate disease may be asymptomatic or cause intermittent claudication.
