RESUMO
To date, no single diagnosis has unified the psychiatric illness and the numerous poorly defined physical complaints that Mary Lincoln (née Todd, 1818-1882) suffered in adulthood. Here, I show that her physical ailments spanned 30 years and included sore mouth, pallor, paresthesias, the Lhermitte symptom, fever, headaches, fatigue, resting tachycardia, edema, episodic weight loss, progressive weakness, ataxia, and visual impairment. Long thought hypochondriacal, these findings, plus their time course and her psychopathology (irritability, delusions, hallucinations, with preserved clarity), are all consistent with vitamin B12 deficiency. Pernicious anemia most probably caused this deficiency: she lacked risk factors for other causes, and her consanguineous parents both derived from a region of Scotland having a high incidence of pernicious anemia. A diagnosis of chronic multisystem pernicious anemia would clarify the conduct of Mary Lincoln as First Lady and widow, and illuminate challenges faced by her husband, President Abraham Lincoln. Her case highlights many forgotten features of the natural history of untreated pernicious anemia and is unique in the medical literature in demonstrating such a course extending over a lifetime.

George Minot (1885-1950) was born in Boston, Massachusetts. He was great grandson of James Jackson, co-founder of Massachusetts General Hospital in 1821. Graduating from Harvard College he enrolled at Harvard Medical School and obtained his MD in 1912. As a house pupil (intern) at the hospital he became interested in diseases of the blood and began taking meticulous histories of dietary habits of patients with anemia.

Increased blood cell regeneration in exsanguinated experimental animals treated either with liver or with aqueous liver extracts was reported by Whipple and by Jeney and Jobling, respectively. These findings stimulated Minot and Murphy to provide evidence for the efficacy of liver against anaemia in clinical studies. After oral administration of liver (45-50 g per day) for 45 patients with anaemia perniciosa improvement of the hematological status was demonstrated. Consequently, for proving the therapeutic value of liver therapy Whipple, Minot and Murphy received Nobel price in 1934. The isolation of the antianemic factor from the liver has been succeeded in 1948 and designated as vitamin B12. At the same time Lucy Wills applied yeast for the treatment of pregnant women with anemia related to undernourishment. The conclusions of this study inspired the discovery of folate. The detailed investigation of the mode of action of vitamin B12 and folate enriched our knowledge in the area of pathophysiology and extended the clinical application of these two drugs.

The use of eponyms has long been contentious, but many remain in common use, as discussed elsewhere (Editorial: Oral Diseases. 2009: 15; 185). The use of eponyms in diseases of the head and neck is found mainly in specialties dealing with medically compromised individuals (paediatric dentistry, special care dentistry, oral and maxillofacial medicine, oral and maxillofacial pathology, oral and maxillofacial radiology and oral and maxillofacial surgery) and particularly by hospital-centred practitioners. This series has selected some of the more recognized relevant eponymous conditions and presents them alphabetically. The information is based largely on data available from MEDLINE and a number of internet websites as noted below: the authors would welcome any corrections. This document summarizes data about Imerslund-Grasbeck syndrome.

Subacute combined degeneration (SCD) is considered the neurological counterpart of pernicious anaemia because it is the paradigmatic neurological manifestation of acquired vitamin B12 (cobalamin (Cbl)) deficiency in adulthood. Hitherto, the theories advanced to explain the pathogenesis of SCD have postulated a causal relationship between SCD lesions and the impairment of either or both of two Cbl-dependent reactions. We have identified a new experimental model, the totally gastrectomised (TGX) rat, to reproduce the key morphological features of the disease, and found new mechanisms responsible for the pathogenesis of SCD. We have demonstrated that the neuropathological lesions in TGX rats are not only due to mere vitamin withdrawal but also to the overproduction of the myelinolytic tumour necrosis factor (TNF)-alpha, nerve growth factor, the soluble(s) CD40:sCD40 ligand dyad, and the reduced synthesis of the neurotrophic agents, epidermal growth factor and interleukin-6. Cbl replacement treatments normalised all of these abnormalities.

In 2005 two 150 years anniversaries, which essentially influenced the development of modern medicine will be celebrated. French physiologist Claude Bernard from College de France published his work "Lectures on Experimental Physiology, applied to medicine" and British medical doctor T. Addison described insufficiency of adrenal cortex, today known as Addison disease.

George Hoyot Whipple (1878-1976) was awarded the Nobel Prize in Physiology and Medicine in 1934, along with Minot and Murphy for their studies in pernicious anemia. Whipple's name has been given to the bacterial disease which he describes in 1907 that we know today as Whipple's disease or intestinal lipodystrophy. He gave the name of thalasemia to the Mediterranean anemia of Cooley, and made diverse contributions to hematology and general pathology. He worked with William Welch in the Department of Pathology at Johns Hopkins Hospital and later became director of the University of Rochester. He died in 1976 at the age of 98.
