Bone marrow in nine cases of clinical glandular fever and a review of the literature.

A review of the literature and the findings of a bone marrow examination in nine patients with glandular fever are reported. All marrows showed marked generalized hyperplasia of erythroid, myeloid, megakaryocytic, and reticulum cell elements with a greater or less ;shift to the left' in the first three cell groups. The hyperplasia was maximal in two cases. Another case (the index case which was responsible for initiating this study) showed extremely bizarre cytological features of all four elements, and from many fields in the marrow smears it would have been possible to make a diagnosis of malignant transformation of any of the four marrow components. All these changes had returned to near normality on repeat marrow examination 15 months later.

Investigation of potential health effects associated with well water chemical contamination in Londonderry Township, Pennsylvania, U.S.A.

A community health survey was conducted by the Pennsylvania Department of Health in Londonderry Township, Dauphin County, Pennsylvania, in response to concerns about potential health effects associated with residential exposure to chemical contaminants in well water. The data indicate that there were no observable adverse health effects in the exposed group of residents, compared with the control group, which could be ascribed to long-term, low-level exposure to trichloroethylene (TCE) and other volatile organic chemicals. Significantly more individuals in the exposed group than in the control group experienced eye irritation, diarrhea, and sleepiness during the 12-month period prior to the survey. This indicated the possibility of an association of contaminated water with the manifestation of symptoms. It is hypothesized that the increased rate of symptoms observed in the exposed group, when compared to the control group, may have been caused by one or more of the following factors: (1) effect of TCE at a threshold level higher than 28 ppb, (2) effect of a single chemical entity other than TCE, and (3) additive or synergistic effects of several chemicals. It is also possible that there are factors other than water contaminants associated with the recorded symptoms, e.g., stress, that may have had an important influence in the exposed group but not in the control group.

Functional impact of a rigid pelvic stabilizer on children with cerebral palsy who use wheelchairs: users' and caregivers' perceptions.

A within-subject ABA design was used to assess the functional impact of a novel wheelchair mounted rigid pelvic stabilizer (RPS) compared with a traditional wheelchair lap belt in a group of six children with cerebral palsy (mean age 10.4 years). The lap belt was worn during the two baseline phases which were each 3 weeks in duration. During a 5 week treatment phase the lap belt was replaced with the RPS device. Using the Canadian Occupational Performance Measure (COPM) each subject's self-evaluated performance ability and satisfaction with performance for five key tasks was measured at the end of each study phase. In addition, a structured weekly interview was conducted with the primary caregivers to assess perceived changes in their child's functional performance with each task. Results of repeated measures ANOVAs were statistically significant, indicating that the RPS as compared to the lap belt is a more effective device. The RPS allowed significantly better occupational performance and satisfaction with performance as measured by the COPM. Single-subject data analyses showed clinically significant changes in task performance and satisfaction with performance when the RPS was worn as compared to the lap belt for all subjects. Caregivers' perception of functional change ratings closely corresponded to subjects' self-rated performance on specific tasks. Visual inspection of subject data also showed that, overall, the increased performance ratings for different tasks during the treatment phase decreased in the second baseline phase, when the RPS was removed, however, performance did not return to initial baseline levels. This suggests that the RPS has a facilitating effect for increasing physical functioning. These results are further discussed in terms of implications for practice, and future research.

Relationship of turnout to hip abduction in professional ballet dancers.

The ability to externally rotate or turn out the hip is fundamental to ballet. Every classical dancer aims to achieve perfect turnout. The purpose of this study was to determine how much turnout is necessary for maximal abduction. It was hypothesized that moderate turnout is sufficient for this purpose. Twenty-two professional dancers from the Alberta Ballet Company were studied. Measurements of passive hip abduction were taken at 0 degree, 45 degrees, 60 degrees, 70 degrees, 80 degrees, 90 degrees and maximum hip lateral rotation using a goniometer and Leighton flexometer. Statistical analysis was done using Pearson correlation coefficients. A significant positive correlation was found between abduction and lateral rotation (P less than 0.05). The greater the position of external rotation, the more abduction achieved. In conclusion, the traditional emphasis on good turnout has some scientific merit and functional implications.

Rubella in the United Kingdom, 1970-1983.

The numbers of acquired and congenital rubella infections in the United Kingdom were obtained from clinical and laboratory reports and from notifications to the National Congenital Rubella Surveillance Programme. Since 1970 the annual frequency of clinical infection has varied from 150 to 450 cases per 100,000 population and laboratory reports of infection, from 800 to 4,100 per year. The number of notified congenital rubella infections varied from 12 to 86 per year. The largest recent epidemics occurred in 1978 and 1979, with an increase in the number of congenital rubella infections during the following winters. Increased numbers of cases occurred every one to three years, with troughs of two to three years, but peaks in different localities often did not coincide. Terminations of pregnancy associated with rubella or rubella vaccination during pregnancy are reported by the Office of Population Censuses and Surveys and vary with the incidence of acquired rubella; a maximum of 830 abortions were performed in 1978 for women who acquired the disease, and from 27 to 156 were performed each year for women vaccinated just before or soon after becoming pregnant. The effect of the vaccination program is discussed in relation to the decrease in the number of young women without rubella antibody.
