A Moment in History

Antoine Louis
(1723–1792)

French surgeon, anatomist, and physiologist. Following his medical studies and a long career as a physiologist, Antoine Louis was named Permanent Secretary of the Royal French Academy of Surgery. His other titles were those of Professor of the Royal Academy, Consultant Surgeon of the Armies of the King, member of the Royal Society of Sciences of Montpellier, Inspector of the Royal Military Hospitals, and Doctor in Law of the University of Paris. As a member of these academies Louis was instrumental in the design and construction of the guillotine. Initially called the "Louisette", this device was later named after another French physician in the same committee, Dr. Joseph-Ignace Guillotin.

Antoine Louis' name is better know to history as the eponymic origin of the "sternal angle" also know as the "Angle of Louis" and synonymously (probably by misspelling or translation) the "angle of Lewis", and "angle of Ludwig". This anatomical landmark is extremely important as it serves as a superficial landmark for important anatomical occurrences (click here).

As a point of controversy, there are some that contest the history of this eponym adjudicating it to Pierre Charles Alexander Louis (1787-1872), another French physician dedicated to the study of tuberculosis.

Depression


This is a series of articles on depression sponsored by TMS Therapy Centers and published as a community service.

UPDATED: Everyone occasionally feels blue or sad. There are also those dreaded "winter blues". But these feelings are usually short-lived and pass within a couple of days, usually with no problems or persistent symptoms. Some may even say that they are "depressed". Although this is true, that person is not clinically depressed.

When an individual has clinical depression, there are physical changes that happen within the brain which reflect in attitudes, mood, symptoms, and actions.

Depression is a common but serious mental disorder that affects over 20 million people in the United States, many of which will never seek diagnosis or treatment. Patients present with depressed mood, loss of interest or pleasure, decreased energy, feelings of guilt or low self-worth, abnormal patterns of sleep or appetite, gruesome nightmares, and poor concentration. Moreover, depression may often come with symptoms of anxiety and varying complex presentations of bipolar disorder.

These problems can become chronic or recurrent and lead to substantial impairments in an individual’s ability to take care of his or her everyday responsibilities. At its worst, depression can lead to a patient's attempt on their life. Clinical Depression interferes with daily life and causes pain for both the individual and their families and loved ones. Patients with depressive disorder often go from one job to another, cannot work, or eventually end in disability, being maintained by their family or loved ones.

Many people afflicted with Major Depressive Disorder (MDD) never seek treatment. This is specially true in males, where the World Health Organization (WHO) estimates that ”fewer than 25% of male sufferers worldwide will seek treatment because of the social stigmas associated with mental disorders including depression.”

Properly and timely treated, even those with the most severe depression, can get better. Medications, psychotherapy, and electroconvulsive therapy (ECT) are the most common methods to treat depression. As patients move from one medication to the next level medication, as well as augmentation medication, the annual cost for medication can be staggering, as well as the common, insidious, and problematic systemic side effects of both the drug therapy as well as the ECT therapy.

The main objective of all treatments for MDD is to attain remission, but in many cases just reducing the symptoms of MDD and reducing the amount and types of medication used is enough to bring the patient back to a productive life and enhance the relationship with their families and loved ones.

Transcranial Magnetic Stimulation (TMS) is a newer treatment approved by the FDA in 2008. TMS has been proven safe and effective in the treatment of MDD with minimal or no side-effects. For more information on TMS click here.
