Indeed, Hodgkin himself did not view his contribution as particularly significant.In 1856, Samuel Wilks independently reported on a series of patients with the same disease that Hodgkin had previously described. Wilks, a successor to Hodgkin at Guys Hospital, was unaware of Hodgkins prior work on the subject. Bright informed Wilks of Hodgkins contribution and in 1865, Wilks published a second paper, entitled "Cases of enlargement of the lymphatic glands and spleen", in which he named the illness "Hodgkins disease" in honor of his predecessor.Theodor Langhans and WS Greenfield first described the microscopic characteristics of Hodgkin lymphoma in 1872 and 1878, respectively. In 1898 and 1902, respectively, Carl Sternberg and Dorothy Reed independently described the cytogenetic features of the malignant cells of Hodgkin lymphoma, now called Reed–Sternberg cells.Tissue specimens from Hodgkins seven cases were preserved at Guys Hospital. Nearly 100 years after Hodgkins initial publication, histopathologic reexamination confirmed Hodgkin lymphoma in only three of seven of these people. The remaining cases included non-Hodgkin lymphoma, tuberculosis, and syphilis.Hodgkin lymphoma was one of the first cancers to be treated successfully with radiation therapy and, later, it was one of the first to be treated by combination chemotherapy. Notable cases
Paul Allen, co-founder of Microsoft was diagnosed with Hodgkin lymphoma in 1982. He later died from non-Hodgkin lymphoma, on October 15, 2018. Eric Berry, All-Pro strong safety for the Kansas City Chiefs of the National Football League, diagnosed in 2014. Howard Carter, Egyptologist and discoverer of the Tomb of Tutankhamun, died in 1939 from Hodgkins disease.
It takes advantage of the differential resistance of foetal hemoglobin to acid. A standard blood smear is prepared from the mothers blood, and exposed to an acid bath. This removes adult hemoglobin, but not foetal hemoglobin, from the red blood cells. Subsequent staining, using Shepards method, makes fetal cells (containing foetal hemoglobin) appear rose-pink in color, while adult red blood cells are only seen as "ghosts". 2000 cells  are counted under the microscope and a percentage of foetal to maternal cells is calculated. Fetal-maternal haemorrhage can also be diagnosed by flow cytometry, using anti-foetal hemoglobin antibodies (anti-HbF). Treatment
If ongoing and rapid haemorrhage is occurring then immediate delivery of the foetus may be indicated if the fetus is sufficiently developed. If the  haemorrhage has already occurred and now stopped, an inutero transfusion of red cells to the foetus may be recommended. References
