Doctor Jean-Emmanuel Kahn



An "internist" is a specialist in all of the medical domains which do not specifically refer to an organ of the body. At time of ultra-specialisation in terms of medical disciplines, Internal Medicine concentrates on a general treatment of patients and harmonises the various specialists involved in treating them where the complexity of their condition requires this.
An internist generally practices in a hospital environment. They must know how to treat patients with common pathologies that require hospitalisation as well as those with conditions that are rare or require complex diagnoses.
They practice a "general", global, holistic and advanced medicine involving patients with multiple pathologies whilst always making room for specialists as specific conditions arise.



Internal medicine treats complex symptoms

In about half of the cases, patients come to the department as part of a programmed hospitalisation after consulting one of the department's doctors or their GP. These patients are often subject to complex conditions or symptoms: fever, inflammation syndromes and/or rare systemic diseases, auto-immune system diseases or other rare diseases... The department must therefore work in close collaboration with the National Reference Centres for each of these rare conditions.



Internal medicine after passing via the Accident & Emergency ward

In the other half of cases, Hôpital Foch receives patients who have been admitted to an A&E ward or who have been released from intensive care. The most common motives for hospitalisation are infectious diseases (pyelonephritis, various forms of pneumonia, lower limb infections often referred to as erysipelas), or more serious infections such as vertebral or heart-valve infections, phlebitis, tumorous diseases, anaemia, etc.
