Chest pain is a very frequent cause of consultation, accounting for over 50% of hospital admissions in cardiology.The vast majority of intra- thoracic organs, from the skin to the heart and oesophagus, as well as several extra- thoracic organs, can be responsible for chest pain. In the emergency setting, the priority is to evoke pain linked to life-threatening pathologies: acute coronary syndrome (ACS), pulmonary embolism (PE), compressive pneumothorax (PNO), aortic tamponade and dissection, oesophageal perforation. The role of the emergency physician is to diagnose chest pain as quickly as possible by means of questioning, clinical examination and ECG, and to ensure immediate revascularization by in-hospital thrombolysis, especially when performed within the first twelve hours of the infarction, provided that contraindications are respected (recent internal hemorrhage, history of cerebral hemorrhage, neurosurgical intervention or recent head trauma).

Respiratory distress is a medical emergency that requires pre-hospital care by the SAMU, and depending on the patient's condition, may lead to hospitalization in intensive care. Among the most frequent causes: acute COPD decompensation, severe acute asthma, pneumothorax, neuromuscular diseases and thoracic trauma.In children, foreign bodies are the most frequent cause of respiratory distress.Diagnosis of respiratory distress is based on clinical findings and gasometric abnormalities (hypoxemia, hypercapnia).Oxygenation using a mask or mask scope is the first line of treatment.All intra- or extra-hospital transport must be assisted by the SAMU.

Cellular senescence is a universal biological mechanism affecting all living organisms. Several situations leading to senescence are linked to the presence of DNA or nuclear envelope damage over time. Unfortunately, we cannot get younger with time, but there are ways to limit aging by eating a diet rich in vitamins that are essential to the proper functioning of our body. The capacity for cell renewal decreases with age. This decrease does not allow the body to react efficiently to different aggressions. Philosophically, old age is of little interest to philosophers, but scientifically, cell death "apoptosis" is genetically programmed. Growing old and dying is a right engraved in our genetic heritage, the luckiest will reach the oldest age. A good old age must be prepared in advance by a good life hygiene. Aging can be slowed down or accelerated depending on the lifestyle of each person.
