Ultrastructure of neutrophilic granulopoiesis in the bone marrow of patients with chronic myeloid leukemia (CML). A morphometric study with special emphasis on azurophil (primary) and specific (secondary) granules

In seven patients with chronic myeloid leukemia (CML) and ultrastructural and morphometric study was performed on neutrophilic granulopoiesis in bone marrow trephine biopsies. Bone marrow specimens from five patients without hematological abnormalities served as controls. In stable phases of CML, abnormalities of the maturing granulocytic lineage were most conspicuously expressed by an infrequently occurring nuclear disfiguration (blebs and disturbed bridging of segments). Morphometric evaluation included the numbers of azurphil (primary) and specific (secondary) granules, the cisternal length of the endoplasmic reticulum and the area of the mitochondrial profiles. These variables could be determined in early and late myeloblasts, promyelocytes, metamyelocytes, band cells and mature polymorphonuclear granulocytes. Statistical analysis with regard to control specimens demonstrated no significant differences in the total amount of neutrophil granules or of the other cell organelles.

[What does the family think? Results of a survey among visitors to the medical care department of a nursing home]

In order to obtain a fuller understanding of the various ideas behind the evaluation of care as provided by nursing homes, 42 regular and frequent visitors of a nursing home, participated in 'open-attitude' interviews. These people had to a great extent adapted their way of life to their regular visits to the nursing home. These relatives of nursing home residents clearly have one common denominator in their various considerations of such care and that is the strong emphasis which in every aspect was placed upon the extent of individual attention given to the residents. The combined functions fulfilled by the nursing home physician, both as a manager of the nursing home and as a general practitioner for the residents, was more than once a subject for discussion by the relatives. These visitors feel the need for the institution of a 'hostess function' (as the investigators formulate it) on the nursing ward. This function should be used in order to provide particular attention to the residents of the nursing home, and should not be too rigidly tied to the (otherwise necessary) institutional routine. A further participation of relatives in certain aspects of care seems quite attainable.
