The pathological anatomy is that branch of medicine that studies the alterations induced by a disease in an organ or in tissue, taken previously during a biopsy or a surgical intervention. Therefore, the pathologist is a doctor who specializes in analyzing the changes that a pathology causes at the level of organs and tissues

Cardiac surgery is that branch of medicine that studies the characteristics and surgical modalities of treating heart diseases. The cardiac surgeon , therefore, is a surgeon specialized in the diagnosis and treatment of heart disease. THE INTERVENTIONS OF CARDIOCHIRURGO The cardiac surgeon dedicates himself mainly to operations on the heart aimed at releasing a narrowing of the coronary arteries, bypassing a coronary obstruction, restoring a defective valve, closing an interatrial or interventricular hole or installing a pacemaker or an implantable defibrillator

Humidity in aircraft cabins is generally less than 10-20%. This poses no health risk, but can cause dry skin and discomfort in the eyes, mouth and nose. To mitigate or prevent the effects of dry cabin air on the skin it is advisable to travel without make-up and apply a good moisturizer. Contact lens wearers, at least for the duration of the flight, should prefer glasses, while those who suffer from dry eyes must frequently instill an eye drop to avoid annoying irritation

The deprivation of the night rest can cause blows of sleep , that is sudden falling asleep. When a person sleeps little during the night, in fact, it is subject to sleepiness and psycho-physical fatigue the next day. The signs that most commonly herald a stroke of sleep are the heavy eyelids, the burning eyes, the frequent yawning, the feeling of cold, the difficulty in focusing, the perception of muffled sounds, the inability to remember the last things made and the state of thoughtlessness

Narcolepsy is a chronic condition, probably linked to a neurological problem, which causes sudden attacks of daytime sleepiness (ie during the day). These particular "sleep attacks" also occur at very active moments of the day : it can happen, in fact, that the narcoleptic individual falls asleep while he is eating, during work or during a conversation

Narcolepsy is a chronic condition, probably linked to a neurological problem, which triggers sudden episodes of daytime sleepiness (ie during the day) These abnormal "sleep attacks" also occur at very active times of the day : it can happen, in fact, that the narcoleptic falls asleep in the middle of a meal, during work or during a conversation

In the hours preceding sleep , it is advisable to avoid exposure to light and sound sources because they condition our biological clock. The light that comes from the TV, from the display screen of the tablet, from smartphones or from the computer, in particular, has the same effect on the brain as the sun: it inhibits the production of melatonin , the sleep hormone, which favors sleep and carries out the fundamental task of regulating the sleep-wake cycle

Lethality rate (case fatality rate) The lethality rate is a statistical tool used in epidemiology to assess the severity of a disease. In particular, the lethality rate of a pathology expresses the number of deaths (for a given disease) in relation to the number of patients (of this disease). The formula for calculating the lethality rate is: L = (N / P), where: L = lethality rate expressed as a percentage N = total number of deaths for a given disease P = total population of subjects affected by this disease For example, if a disease affects 1, 000 people causing 100 deaths, the fatality rate

Morbidity and morbidity are statistical indices used in epidemiology to assess the severity of a disease. Morbidity (or morbidity rate) expresses the relationship between the number of patients and the overall population under study. Therefore, if a disease has a high morbidity rate in Italy, it means that many Italians are affected by this disease
