Hematology all time.

Cooley’s anemia:                                                                      Thomas Benton Cooley Beta Thalassemia major (inherited disorder due to defects in globin chain biosynthesis) also known as Cooley’s anemia, is named after Thomas Benton Cooley, an American pediatrician and hematologist and professor of hygiene and medicine at the University of Michigan and Wayne State University. He noted similarities in appearance and clinical course of four children of Greek and Italian ancestry who had severe anemia, massive hepatosplenomegaly, bone deformities and severe growth retardation. He called it as erythroblastic anemia which later was popularly known as Cooley’s anemia and then thalassemia. He presented his findings to the American Pediatric Society in 1925. Diamond Blackfan anemia (DBA):                                                     Louis Klein Diamond and Kenneth Blackfan DBA is one of the inherited bone marrow failure syndromes, characteriz

June 19 is observed as “World Sickle cell day” every year. On 22 nd December 2008, The United Nations General Assembly decided to celebrate “World Sickle cell day” on June 19 every year to raise awareness about Sickle cell disease. Sickle cell disease is recognized as a public health problem and ‘one of the world’s foremost genetic diseases’. In this post, lets see the history of sickle cell disease (SCD). SCD was first discovered in 1910 in medical history. But it was known in Africa even atleast five thousand years before and was called by various names. Here it goes, how the SCD came into light in medicine. A young dental student, Walter Clement Noel from the island of Grenada, was studying in Chicago. He had complaints of pain and symptoms of anemia, for which he visited a cardiologist Dr. James B.Herrick. Noel was seen by Herrick resident Dr.Ernest Irons as Herrick was not interested in this case.                                                    

June 14 is celebrated as World Blood donor day every year. This day is celebrated to thank the blood donors who donate blood to save lives. Why is it so important to celebrate a day to thank blood donors? Are they great people?   Yes they are the real life heroes, as they donate blood to save the lives of fellow human beings. Today being June 14, I thought of writing a post about it. If anyone has a doubt if I have donated blood.. YES, I have donated blood and am happy to be a voluntary blood donor. First time is always special and I am sharing my experience, how I felt the first time when I donated blood, in this post. I did my MBBS from JIPMER ,Puducherry.   During my internship, I decided to donate blood and I did the same on February 4, 2009, eleven years back, on my parents wedding anniversary.    I went to the blood bank, they collected my preliminary details, checked my hemoglobin, and when they found me fit, I was taken for the procedure

In this post, lets see some more eponyms in hematology related to food. 1.

Eponyms are commonly used in pathology. It makes easier to learn and remember the subject. And when we have eponyms related to food, it makes even more easier as everyone, am sure, is fond of food.   In this post, lets see some of the food eponyms in hematology. 1.      Ague cake appearance used to describe enlargement of spleen in Malaria. 2.     Banana shaped  gametocytes seen in Plasmodium falciparum infection. 3.     Clover leaf cells seen in Adult T- cell leukemkia/lymphoma. 4.     Doughnut cells seen in anaplastic large cell lymphoma . The nucleus is ring shaped with a central opening resembling doughnut. 5.     Egg in basket appearance – Multinucleated   Reed Sternberg cells seen in Hodgkins lymphoma. We will see  more food eponyms related to hematology in the next post.  Click this  link to see more https://hematologyalltime.blogspot.com/2020/06/food-eponyms-in-hematology-part-2.html REFERENCES: 1.      Food

Have you ever wondered what onyms are?   .. In my previous posts, I have discussed about Burkitt lymphoma. The lymphoma got the name of the doctor who described it acknowledging him for his contributions. Also, we saw Epstein Barr virus got its name from two scientists who first cultured it. We all know there are various diseases named after scientists or doctors who described it.  Do diseases are named only after the discoverer or the scientist only? Or is there anything else? Its interesting to know that some are named after patients in whom it was described first, some after place or hospital where it was first described. Also some names are derived from foods, due to their resemblance with the food. I was reading about the various eponyms in hematology and I learnt that there are other –onyms also and I found it to be interesting. I thought why not share this with you also. And hence this post. The –onym, comes from the Greek word ‘onyma’ meaning ‘name’.

We all are familiar with microscopes, even from our school days.  The word ‘microscope’ comes from two Greek words, “uikpos” means small and “okottew” means view. During my school days, I have seen biology specimens using a single eyed simple microscope, it continued during my MBBS days as well, starting from single eyed simple microscope to compound microscope from my MBBS to MD pathology days. These days we have the latest microscopes, compound microscope, inverted microscope, confocal microscope, fluorescent microscope, electron microscope etc ... But how the thought of magnifying tiny things started with people... In lay man language, microscope is an optical instrument which can magnify very minute things so that we can appreciate the finer details. The history of microscope started way back in the first century with the development of glasses by the ancient Romans and Egyptians. So initially they observed how various types of glasses made objects appear bigger a
