The effect of a whole body exercise programme and dragon boat training on arm volume and arm circumference in women treated for breast cancer.

The purpose of this study was to examine the effect of a whole body exercise programme and dragon boat training on changes in arm volume in breast cancer survivors. A total of 16 female breast cancer survivors with no clinical history of lymphoedema volunteered. The 20-week exercise programme consisted of resistance and aerobic exercise with the addition of dragon boat training at week 8. Arm circumference at two sites (CIRC10, CIRC15), arm volume (VOL), and upper body strength (1-RM) were measured at baseline (T1), week 8 (T2), and week 20 (T3). All statistical tests were two-sided (alpha < or = 0.05). No significant differences between the ipsilateral and contralateral upper extremities at any of the three time points were found. All variables significantly increased from T1 to T3 (CIRC10: difference, d = 0.49 cm, 95% confidence interval, CI = 0.25-0.73, P = 0.000; CIRC15: d = 1.33 cm, CI = 0.78-1.88, P = 0.000; VOL: d = 100 mL, CI = 69-130, P = 0.000). As well, 1-RM significantly increased from T1 to T3 (d = 10.8 kg, CI = 5.6-16.1; P = 0.000). In summary, participation in a whole body exercise programme and dragon boat training resulted in a significant increase in upper extremity volume over time. However, the changes were consistent for both arms and the significant gain in upper body muscular strength likely accounted for the increase in arm volume.

Crossreacting human lymphoma idiotypes.

We have examined an unselected series of 72 lymphomas of diverse histologies with a panel of mouse monoclonal antibodies specific for human B-lymphoma-derived Ig idiotypes (anti-ids) to determine the nature and extent of id/anti-id crossreactivity. The anti-id antibodies were prepared from Ig isolated from seven follicular center cell lymphomas by heterohybridoma technique. Thirty-six of 75 individual anti-ids obtained in this manner were further selected based on their reactivity with highly restricted or private idiotypic determinants. Twelve of the 72 (17%) lymphoma biopsies reacted with one or more of the 36 anti-ids that detect private determinants. A pool consisting of five individual antibodies would have detected 11 of the 12 crossreacting tumors. Staining of tumor cell populations was homogeneous in the positive cases, suggesting uniform idiotype expression. If there was a segregated staining pattern, it was generally related to the presence of CD3+ T cells in the section. These follicular center cell-derived anti-ids cross-reacted with follicular center cell tumors of all histologic grades with frequencies ranging from 13% to 50%. The structural basis for the crossreactivity of our lymphoma-derived private anti-ids is as yet not known. However, the reactivity of certain anti-ids with both kappa- and lambda-expressing tumors suggests a biased use of V gene segments in these crossreactive clones that is probably related to the VH gene. These data suggest the possibility that lymphoma may develop in a highly restricted pool of normal differentiated B cells or in B-cell subsets that express a limited repertoire of unmutated VH gene segments.

Idiopathic hirsutism--an ovarian abnormality.

We investigated increased production of testosterone and androstenedione in 44 women with unexplained adult-onset hirsutism, 41 of whom had normal-sized ovaries. Twenty women in this group had at least 50 per cent suppression of plasma testosterone and androstenedione after four to five days of dexamethasone. Testosterone and androstenedione values in ovarian-vein effluents were higher than those of their adrenal veins. We calculated adrenal secretion rates of both androgens in each patient by relating the adrenal gradients to those of cortisol. In 42 of the hirsute women, including those whose androgens were suppressed after dexamethasone, the ovaries were the predominant source of androgen production. The women with dexamethasone suppression had milder degrees of virilism and lower production rates of testosterone and androstenedione. We conclude that the ovaries are the source of excessive androgens in most women with unexplained hirsutism, and that corticoid-suppressible patients have milder forms of ovarian hyperandrogenism.

Concurrence of aldosterone, androgen, and cortisol secretion in adrenal venous effluents.

Adrenal effluent concentrations of aldosterone were measured along with testosterone, androstenedione, and cortisol in 17 women with idiopathic hirsutism. In the basal state, aldosterone secretion (higher concentrations vs peripheral blood) was demonstrated in 14 out of 16 of the women, in contrast to 8 out of 16 who demonstrated cortisol gradients. Nine women received 0.25 mgm beta 1-24 ACTH im and serial adrenal venous blood samples were obtained over the next 30 minutes. Parallel 30-40-fold increments were noted in aldosterone, androstenedione, and cortisol; testosterone increased only 8-fold. These marked changes in adrenal effluents were not observed in simultaneously monitored peripheral blood. Minimal changes in these steroid concentrations were noted in adrenal and peripheral blood in 7 women who received 2,000 IU hCG. One woman received a pressor dose of angiotensin II, resulting in a marked increase in adrenal vein aldosterone and a simultaneous decrease in cortisol. Since adrenal androgen secretion parallels cortisol, quantification of adrenal androgen secretion rates can be achieved by sampling the adrenal effluent and relating the androgen gradient to that of cortisol at any given time. In contrast, aldosterone secretion is often independent of cortisol, and thus cannot be estimated by comparison of adrenal gradients. ACTH administration, however, invariably stimulated aldosterone secretion, enabling us to quantify the "ACTH-related aldosterone secretion rate" from a comparison of maximal adrenal gradients of aldosterone vs cortisol. In 6 women, "ACTH-related aldosterone" secretion rate averaged 40 mug/day, roughly 20% of the total daily aldosterone secretion rate.
