Bone histomorphometry: Standardization of nomenclature, symbols, and units: Report of the asbmr histomorphometry nomenclature committee

Abstract: RACTITIONERS OF BONE HISTOMORPHOMETRY communicate P with each other in a variety of arcane languages, which in general are unintelligible to those outside the field. Many in the bone and mineral scientific community would like to keep abreast of the contributions of histology to their subject, but are dismayed by the semantic barriers they must overcome. The need for standardization has been recognized for many years,(') during which there has been much talk but no action. To meet the needs of ASBMR members, Dr. B.L. Riggs (President, 19851986) asked the senior author to convene a committee of the Society to develop a unified system of termnology, suitable for adoption by the Journal of Bone and Mineral Research as part of its Instructions to Authors. The committee includes members from Europe and Canada as well as the U.S., and represents most existing systems of nomenclature. A circular letter seeking suggestions and information on current usage was sent to several hundred persons, with names drawn from the Society membership roster and lists of attendees at various recent conferences, to which approximately 40 replies were obtained. These confirmed the magnitude of the semantic problem (for some measurements as many as nine different terms were in use) and suggested a range of solutions likely to be generally acceptable. In formulating the new system. the committee kept in mind certain agreed general principles. First, the primary reason for change was to help other scientists understand bone histomorphometry, not to help bone histomorphometrists undcntand each other. Second. names should be self-explanatory and dcscriptive, without implicit assumptions. Third. symbols should consist mainly of abbreviations that included the first letter of each word in the same order as in the name. without subscripts or superscripts. Fourth. each symbol component should have one and only one meaning, and so eliminate ambiguity. Fifth, primary measurements should be clearly distinguished from derived indices. Finally, the chosen system should be sufficiently flexible to apply to all surfaces and all types of bone, and to accommodate any new primary measurement or derived index. The recommended system shares common elements with. but also differs substantially from. all those in current usc. was tested in practice for several months before the final forniat was chosen, and is as complex and conceptually difficult ;I\\ the field with which it deals. For those within the field we hope that increased readership of their papers will be adequate conipensation for the inconvcnicncc of learning a new systcm. For those outside the field, mastering the new system will be hard work, but if we are able to secure its acceptance by all journals with an interest in bone and mineral metabolism, the effort will only have to be expended once rather than. as at present. rcpeated many times. To this end we give the reasons for our decisions in the areas of controversy and, as well as definitions, provide methods for calculation of derived indices and

Traumatic events and posttraumatic stress disorder in an urban population of young adults

Abstract: \s=b\To ascertain the prevalence of posttraumatic stress disorder (PTSD) and risk factors associated with it, we studied a random sample of 1007 young adults from a large health maintenance organization in the Detroit, Mich, area. The lifetime prevalence of exposure to traumatic events was 39.1%. The rate of PTSD in those who were exposed was 23.6%, yielding a lifetime prevalence in the sample of 9.2%. Persons with PTSD were at increased risk for other psychiatric disorders; PTSD had stronger associations with anxiety and affective disorders than with substance abuse or dependence. Risk factors for exposure to traumatic events included low education, male sex, early conduct problems, extraversion, and family history of psychiatric disorder or substance problems. Risk factors for PTSD following exposure included early separation from parents, neuroticism, preexisting anxiety or depression, and family history of anxiety. Life-style differences associated with differential exposure to situations that have a high risk for traumatic events and personal predispositions to the PTSD effects of traumatic events might be responsible for a substantial part of PTSD in this population.

Human Papillomavirus and Cervical Cancer

Abstract: Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whether cervical cancer will develop. Early detection and treatment of precancerous lesions can prevent progression to cervical cancer. Identification of precancerous lesions has been primarily by cytologic screening of cervical cells. Cellular abnormalities, however, may be missed or may not be sufficiently distinct, and a portion of patients with borderline or mildly dyskaryotic cytomorphology will have higher-grade disease identified by subsequent colposcopy and biopsy. Sensitive and specific molecular techniques that detect HPV DNA and distinguish high-risk HPV types from low-risk HPV types have been introduced as an adjunct to cytology. Earlier detection of high-risk HPV types may improve triage, treatment, and follow-up in infected patients. Currently, the clearest role for HPV DNA testing is to improve diagnostic accuracy and limit unnecessary colposcopy in patients with borderline or mildly abnormal cytologic test results.
