Auguste Rollier (1 October 1874 - 30 October 1954) was a Swiss physician best known for his research on heliotherapy.
Rollier was born at Saint-Aubin, Fribourg. He was educated at Zurich and Berne Universities and graduated in medicine in 1898. [1] He worked under Emil Theodor Kocher for four years. In 1903, Rollier opened his Institute of Heliotherapy in Leysin. [2] He advocated fresh air, physical exercise, rest and sunshine to treat his patients. He became known for his treatment of skeletal tuberculosis by heliotherapy (light therapy). [3] He combined sunbathing with climatic treatment by cold air and high altitude. [4] After World War I, it was reported that 1746 of 2167 patients had recovered their health under his care. [2]
Rollier was influenced by the research of Niels Ryberg Finsen and established sunbathing clinics in the Swiss Alps. R. A. Hobday noted that "Rollier practised sunlight therapy at Leysin for over forty years and had thirty-six clinics with a total of more than 1,000 beds." [5] After antimicrobial therapy became available, heliotherapy for tuberculosis was no longer practiced. [6] Rollier was elected an honorary member of the American Clinical and Climatological Association in 1923. [3]
Sir Alexander Fleming was a Scottish physician and microbiologist, best known for discovering the world's first broadly effective antibiotic substance, which he named penicillin. His discovery in 1928 of what was later named benzylpenicillin from the mould Penicillium rubens has been described as the "single greatest victory ever achieved over disease". For this discovery, he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain.
Antidepressants are a class of medications used to treat major depressive disorder, anxiety disorders, chronic pain, and addiction.
Hypnosis is a human condition involving focused attention, reduced peripheral awareness, and an enhanced capacity to respond to suggestion.
Naturism is a lifestyle of practicing non-sexual social nudity in private and in public; the word also refers to the cultural movement which advocates and defends that lifestyle. Both may alternatively be called nudism. Though the two terms are broadly interchangeable, nudism emphasizes the practice of nudity, whilst naturism highlights an attitude favoring harmony with nature and respect for the environment, into which that practice is integrated. That said, naturists come from a range of philosophical and cultural backgrounds; there is no single naturist ideology.
Cystic fibrosis (CF) is a rare genetic disorder that affects mostly the lungs, but also the pancreas, liver, kidneys, and intestine. The hallmark feature of CF is the accumulation of thick mucus in different organs. Long-term issues include difficulty breathing and coughing up mucus as a result of frequent lung infections. Other signs and symptoms may include sinus infections, poor growth, fatty stool, clubbing of the fingers and toes, and infertility in most males. Different people may have different degrees of symptoms.
Gout is a form of inflammatory arthritis characterized by recurrent attacks of a red, tender, hot and swollen joint, caused by the deposition of needle-like crystals of uric acid known as monosodium urate crystals. Pain typically comes on rapidly, reaching maximal intensity in less than 12 hours. The joint at the base of the big toe is affected (Podagra) in about half of cases. It may also result in tophi, kidney stones, or kidney damage.
Acne, also known as acne vulgaris, is a long-term skin condition that occurs when dead skin cells and oil from the skin clog hair follicles. Typical features of the condition include blackheads or whiteheads, pimples, oily skin, and possible scarring. It primarily affects skin with a relatively high number of oil glands, including the face, upper part of the chest, and back. The resulting appearance can lead to lack of confidence, anxiety, reduced self-esteem, and, in extreme cases, depression or thoughts of suicide.
In medicine, comorbidity—from Latin morbus ("sickness"), co ("together"), -ity —is the presence of one or more additional conditions often co-occurring with a primary condition. Comorbidity describes the effect of all other conditions an individual patient might have other than the primary condition of interest, and can be physiological or psychological. In the context of mental health, comorbidity often refers to disorders that are often coexistent with each other, such as depression and anxiety disorders. The concept of multimorbidity is related to comorbidity but presents a different meaning and approach.
The spread of HIV/AIDS has affected millions of people worldwide; AIDS is considered a pandemic. The World Health Organization (WHO) estimated that in 2016 there were 36.7 million people worldwide living with HIV/AIDS, with 1.8 million new HIV infections per year and 1 million deaths due to AIDS. Misconceptions about HIV and AIDS arise from several different sources, from simple ignorance and misunderstandings about scientific knowledge regarding HIV infections and the cause of AIDS to misinformation propagated by individuals and groups with ideological stances that deny a causative relationship between HIV infection and the development of AIDS. Below is a list and explanations of some common misconceptions and their rebuttals.
Gerhard Johannes Paul Domagk was a German pathologist and bacteriologist.
Sun tanning or tanning is the process whereby skin color is darkened or tanned. It is most often a result of exposure to ultraviolet (UV) radiation from sunlight or from artificial sources, such as a tanning lamp found in indoor tanning beds. People who deliberately tan their skin by exposure to the sun engage in a passive recreational activity of sun bathing. Some people use chemical products which can produce a tanning effect without exposure to ultraviolet radiation, known as sunless tanning.
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, and skin wound infections. Treating skin conditions such as neurodermatitis, psoriasis, acne vulgaris, and eczema with ultraviolet light is called ultraviolet light therapy.
Sir John Fraser, 1st Baronet, was Regius Professor of Clinical Surgery at Edinburgh University from 1925 to 1944 and served as principal of the University of Edinburgh from 1944 to 1947.
Alfred (Al) Sommer is a prominent American ophthalmologist and epidemiologist at the Johns Hopkins Bloomberg School of Public Health. His research on vitamin A in the 1970s and 1980s revealed that dosing even mildly vitamin A deficient children with an inexpensive, large dose vitamin A capsule twice a year reduces child mortality by as much as 34 percent. The World Bank and the Copenhagen Consensus list vitamin A supplementation as one of the most cost-effective health interventions in the world.
Hydroxyprogesterone caproate, sold under the brand names Proluton and Makena among others, is a medication used to reduce the risk of preterm birth in women pregnant with one baby who have a history of spontaneous preterm birth. In March 2023, the manufacturer, Covis Pharma, agreed to withdraw the drug from the US market. The approvals of Makena and its generics were withdrawn by the US Food and Drug Administration (FDA) in April 2023.
Atrial fibrillation is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. It often begins as short periods of abnormal beating, which become longer or continuous over time. It may also start as other forms of arrhythmia such as atrial flutter that then transform into AF.

The side effects of cyproterone acetate (CPA), a steroidal antiandrogen and progestin, including its frequent and rare side effects, have been studied and characterized. It is generally well-tolerated and has a mild side-effect profile, regardless of dosage, when it used as a progestin or antiandrogen in combination with an estrogen such as ethinylestradiol or estradiol valerate in women. Side effects of CPA include hypogonadism and associated symptoms such as demasculinization, sexual dysfunction, infertility, and osteoporosis; breast changes such as breast tenderness, enlargement, and gynecomastia; emotional changes such as fatigue and depression; and other side effects such as vitamin B12 deficiency, weak glucocorticoid effects, and elevated liver enzymes. Weight gain can occur with CPA when it is used at high doses. Some of the side effects of CPA can be improved or fully prevented if it is combined with an estrogen to prevent estrogen deficiency. Few quantitative data are available on many of the potential side effects of CPA. Pooled tolerability data for CPA is not available in the literature.
Convalescent plasma is the blood plasma collected from a survivor of an infectious disease. This plasma contains antibodies specific to a pathogen and can be used therapeutically by providing passive immunity when transfusing it to a newly infected patient with the same condition. Convalescent plasma can be transfused as it has been collected or become the source material for the hyperimmune serum which consists largely of IgG but also includes IgA and IgM. or as source material for anti-pathogen monoclonal antibodies, Collection is typically achieved by apheresis, but in low-to-middle income countries, the treatment can be administered as convalescent whole blood.
