Template:Wikify Template:Inappropriate tone Template:Infobox Person Charles Alan Blake "Alan" Clemetson MD, F.R.C.O.G., F.R.C.S.(C), F.A.C.O.G. (October 31 1923 – August 30 2006) was a medical doctor, scientist and researcher who published over 48 medical papers and a three-volume monograph, Vitamin C.[1] During his hospital and teaching career he specialised in obstetrics and gynecology. After retirement in 1991 he devoted his time to researching and publishing papers on Barlow's disease (scurvy in infants), particularly arguing this to be the major cause of Shaken baby syndrome.

Biography

Dr. Clemetson was born in Canterbury, England, attending Wootton Court preparatory school, Wootton, Kent (1930-1935) and The King's School, Canterbury (1935-1942). After preclinical studies at Magdalen College, University of Oxford, he completed his training at Radcliffe Infirmary, graduating from Oxford University in 1948 with a Bachelor of Medicine & Bachelor of Surgery (B.M., B.Ch) degree.[2]

He married Helen Cowan Forster, a physiotherapist, on March 29, 1947. They had four children.[2]

After graduation, he became a Royal Air Force medical officer for two years, and then returned to Oxford University in 1950 for a MA degree. In 1950, as a research assistant in Obstetrics, he started to pursue research into preeclamptic toxaemia and started to publish medical papers in 1953. In 1951-1952, he was named a Nichols Research Fellow of the Royal Society of Medicine. From 1952 through 1956, he served at various hospitals in England as the House Surgeon of either Obstetrics or Gynecology, and, in 1956, became a lecturer in Obstetrics and Gynecology at London University.

Dr. Clemetson immigrated to Saskatoon, Canada (1958 -1961), becoming an assistant professor of Obstetrics and Gynecology at the University of Saskatoon. During this period he began to be interested in vitamin C, on an expedition to Rankin Inlet, Hudson Bay, when he was impressed by the good capillary strength of the local Inuit, surmising this to be due to raw fish in their diet.[2]

Then, in 1961, he moved to California and assumed a position as an assistant professor of Obstetrics and Gynecology at the University of California Medical Center in San Francisco, and a lecturer in the Department of Maternal and Child Health with the University of California, Berkeley.

In 1967, he assumed a teaching position (1967–1972) as an assistant professor of Obstetrics and Gynecology with the State University of New York, Brooklyn. He also became the Director of the Obstetrics and Gynecology Department (1967-1981) at the Methodist Hospital of Brooklyn, New York. In addition (1972-1981), he served as a professor in the Department of Obstetrics and Gynecology at the Downstate Medical Center of the State University of New York, Brooklyn, New York.

Dr. Clemetson in 1981 moved to New Orleans, Louisiana, and became a professor of Obstetrics and Gynecology at Tulane University School of Medicine, and the Director of Obstetrics and Gynecology at the Huey P. Long Memorial Hospital, Pineville, Louisiana. He also became a consultant in Gynecology for the Department of Surgery, Veterans Administration Hospital, Pineville, Louisiana.

Upon his retirement in 1991, as a Professor Emeritus, Tulane University School of Medicine, Dr. Clemetson devoted his remaining years to writing and publishing medical papers concerning Shaken baby syndrome.

Near the end of his life he narrowly escaped the New Orleans disaster from Hurricane Katrina, having been warned by the meteorologist brother-in-law of his carer. He escaped with the latter over the Lake Pontchartrain bridge the day before it was destroyed. He lived in Houston, Texas for nearly a year while his family restored his house, but died of heart failure a few weeks after this was completed.[2]

Achievements

Dr. Clemetson had a long and distinguished academic career as a medical doctor, scientist and researcher. During his forty year professional career, he implemented numerous scientific studies and was instrumental in furthering scientific knowledge. The following listed achievements are highlights of his life’s work that are contained in his extensive Curriculum Vitae.

Dr. Clemetson's most notable medico-legal achievement was as the father of the “Motherhood Bill”, which requires that all medical insurance carriers in the State of New York include coverage for pregnancy and complications of pregnancy. This so-called Donovan Bill rapidly spread to all 50 states.

    • University College Hospital – London – 1950-1952 / 1956-1958
      • Demonstrated the effects of cord around the neck and of preeclampsia on the oxygen saturation of newborn infants.
      • Published the first study of “small-for-dates” infants in his studies of “the difference in birth weight of human twins.”
      • Demonstrated impaired active transfer of amino acids from mother to fetus in preeclampsia.
      • Demonstrated aortic hypoplasia in some patients following severe early preeclampsia.
      • Performed and published successful open cardiac massage outside of hospital.
    • University of California Medical Center – San Francisco – 1961–1967
      • Bioflavonoids and catechins - Solved the old “Vitamin P” problem, by showing that bioflavonoids with certain structural characteristics act as indirect antioxidants for Vitamin C. See: Plant Polyphenols Monograph in New York Academy of Sciences.
      • Preeclampsia - Demonstrated a disturbance of ascorbic acid metabolism in preeclampsia and in abruptio placentae.
    • Methodist Hospital of Brooklyn – New York – 1967–1981
      • Developed a new method for measuring the bilirubin content of amniotic fluid.
      • In collaboration with the Department of Anesthesiology, he showed an improved oxygen saturation in the umbilical cord of blood of babies delivered by Caesarean Section under spinal anesthesia when the mother is placed in a left-side-down tilt position.
      • In collaboration with Drs. Mallikarjuneswara and Moshfeghi, he was able to measure the electrical charge on fertilized rat ova, and this was the first time that anyone had ever measured the electrical charge on any mammalian ovum.
      • He showed conclusively that women on the pill need more Vitamin C than usual, and, as a result of this, a special vitamin formula called “Feminins” was developed and marketed for women on the pill.
      • His research on the uterine luminal fluid in the rat showed that estrogen causes secretion and progesterone causes reabsorption of uterine luminal fluid.
      • In collaboration with Dr. J.K. Kim and others, he showed that the luteal phase of the human menstrual cycle is the reabsorptive phase, and not the secretory phase.
      • In recent research, he has shown that people with low vitamin C levels have very high blood histamine levels.
      • He was able to relate the above observation to abruptio placentae, as women with low ascorbate (Vitamin C) and high histamine levels are prone to develop premature separation of the placenta.
    • Tulane University School of Medicine 1981–1990
      • Wrote three-volume monograph, Vitamin C,[1] published by CRC Press in 1989.

Medical hypotheses

In 1964, Dr. Clemetson conducted and published the first studies[3] concerning ascorbic acid (vitamin C) metabolism and depletion in preeclampsia.

After Dr. Clemetson’s retirement from teaching in 1991, his work focused on developing the hypothesis that the hemorrhages seen in infants with Shaken baby syndrome are caused not by inflicted trauma, but by capillary damage due to Barlow's disease (subclinical scurvy) - a condition called by proponents Clemetson/Kalokerinos syndrome. The mechanism he argued to be high histamine levels associated with low serum vitamin C, the latter deficiency arising before birth due to factors such as the pregnant mother's malnutrition, and in the infant by recurrent infections and recent multiple vaccinations.[2]

His four main papers on this topic, published in the journal Medical Hypotheses, are: The Key Role of Histamine in the Development of Atherosclerosis and Coronary heart disease[4]; Barlow's disease (2002) [5]; Capillary Fragility as a Cause of Subdural Hemorrhage in Infants (2004)[6]; and Elevated Blood Histamine Caused by Vaccinations and Vitamin C Deficiency May Mimic the Shaken Baby Syndrome (2004).[7]
