13. Comparison of the diagnostic value of bone marrow biopsy and bone marrow aspiration in neoplastic disease
The Jamshidi-Swaim biopsy needle was utilized to perform 205 bone marrow biopsies, accompanied by simultaneous bone marrow aspirates, on patients with lymphoma, leukaemia, and a variety of solid tumours. There was no significant morbidity. There were 67 positive findings with biopsy and 42 with aspiration. The two techniques were complementary in Hodgkin's d

14. Trained nurses can obtain satisfactory bone marrow aspirates and trephine biopsies.
AIMS: To assess the feasibility of training nurse practitioners to perform bone marrow aspiration and trephine biopsy, and to compare the quality of these samples with those obtained by medical staff. METHODS: A retrospective audit was undertaken of nurse practitioner and medical staff performance in bone marrow procedures in a busy haematology day unit. RES

16. Yield of bone marrow culture in the diagnosis of infectious diseases in patients with acquired immunodeficiency syndrome.
The yield in cultures of bone marrow aspirations or biopsies was determined in 50 patients with acquired immunodeficiency syndrome. Most patients were febrile and had no identifiable source of infection. Concurrent stool, urine, and blood samples were also cultured. The bone marrow aspiration and biopsy procedures produced no complications and enabled a micr

17. Use of monoclonal anti-actin as a megakaryocyte marker in paraffin wax embedded bone marrow biopsy specimens.
Monoclonal anti-actin was used as a marker of megakaryocytes in Zenker's fixed, paraffin wax embedded bone marrow tissue, using an immunoperoxidase staining method. Twenty bone marrow samples were studied, including controls, and different myeloproliferative and myelodysplastic syndromes. The results were compared with those obtained using factor VIII relate

18. A comparison of peripheral blood and buffy coat smear examination for the prediction of bone marrow relapse of acute lymphoblastic leukaemia in childhood.
In an attempt to see if buffy coat smear examination might be an alternative to bone marrow aspiration for predicting relapse, 98 consecutive bone marrow aspirates from 96 children with acute lymphoblastic leukaemia were examined blind with buffy coat and peripheral blood from the same patients. The 28 bone marrow aspirates from children no longer on treatme

19. Collagenase digestion of bone marrow trephine biopsy specimens: an important adjunct to haematological diagnosis when marrow aspiration fails.
Failure to obtain sufficient material from marrow aspiration (dry tap) posed a diagnostic problem in two patients with pancytopenia. By using collagenase digestion of the trephine biopsy specimen, a precise diagnosis was reached. This technique is very useful because it permits flow cytometric and immunocytochemical analyses of cell suspensions obtained afte

20. The bone marrow in aplastic anaemia: Diagnostic and prognostic features
Bone marrow preparations were examined from 80 patients with aplastic anaemia. The degree of cellularity varied greatly and in a third of the cases it was normal or even hypercellular at one site of aspiration. In the severely hypoplastic marrows lymphoid cells were predominant and this situation was associated with a worse prognosis. There was no correlatio

21. Bone marrow biopsy in monoclonal gammopathies: correlations between pathological findings and clinical data. The Cooperative Group for Study and Treatment of Multiple Myeloma.
Between January 1987 and October 1989, 561 consecutive untreated patients with monoclonal gammopathy of undetermined clinical importance (MGUS) (n = 295) or with multiple myeloma (n = 266) were evaluated in a multicentre trial. Both bone marrow biopsy and aspiration (performed at different anatomical sites) were required at presentation. Bone marrow biopsy d

22. An appraisal of bone marrow biopsy in assessment of sick dogs.
Dogs were classified into a number of disease categories according to hematological, cytological and serochemical changes. Aspiration and core bone marrow biopsies were examined in 128 dogs in the various disease categories and compared to marrow samples in 36 dogs which appeared clinically normal. Differential cell counts on bone marrow smears were examined

23. Correlation of peripheral white cell and bone marrow changes with folate levels in pregnancy and their clinical significance
Two hundred and thirty-eight `megaloblastic' pregnancies are reviewed. Bone-marrow aspiration was performed in every case. Serum folate estimations were strongly suggestive of folic acid deficiency in only 34% of cases. If, however, the red cell folate was determined as well, there was an almost complete agreement with the changes in the erythroblasts. It is

24. Papillary thyroid carcinoma after total body irradiation.
Two children developed papillary thyroid carcinoma after allogeneic bone marrow transplantation (BMT) probably due to radiotherapy during remission and pretransplantation conditioning. Establishing a relationship between the cellular thyroid stimulating hormone (TSH) effect and development of carcinoma in cases with high serum TSH concentrations is difficult
