Do endocrines play an etiological role in diabetic and nondiabetic sexual dysfunctions?

Sexually dysfunctional diabetic and nondiabetic males were compared with a group of normal controls using different endocrinological, psychophysiological, and psychological parameters. One hundred male subjects participated in this study: 47 diabetics with sexual dysfunction (DD), 31 nondiabetics with sexual dysfunction (NDD), and 22 normal controls (C). They were evaluated by an internist (physical examination and medical history), a psychologist (psychological and sexual functioning tests), a psychiatrist (psychiatric history and mental status examination), a urologist (genitourinary physical examination), and an endocrine biochemist (evaluation of endocrine factors). Additionally, subjects were evaluated for nocturnal penile tumescence (NPT) during three nights in the sleep laboratory to obtain a differential diagnosis of impotence, that is, psychogenic vs. organic. Both sexually dysfunctional groups showed significant differences on several measures in the psychological and psychophysiological evaluations. There were also significant differences between these two groups and the control group. Plasma levels of total testosterone and serum levels of prolactin, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) showed no significant differences among the three groups, but there were some significant correlations between the endocrine and psychological measures. No significant correlations were found between the endocrine and psychophysiological measures.

Changes in cognitive coping skills and social support during cognitive behavioral stress management intervention and distress outcomes in symptomatic human immunodeficiency virus (HIV)-seropositive gay men.

OBJECTIVE: We have previously reported decreases in dysphoria, anxiety, and total mood disturbance in symptomatic HIV seropositive gay men after a 10-week cognitive behavioral stress management (CBSM) group intervention. This structured intervention was designed a) to increase cognitive and behavioral coping skills related to managing the distress of symptomatic HIV, and b) to increase social support among group members. Here we examine the relative contribution of changes in coping skills and social support during the intervention period to reductions in dysphoria, anxiety, and distress-related symptoms in this sample. METHODS: Participants were randomized to a 10-week CBSM group intervention or to a wait-list control condition. Coping, social supports, and mood were measured before and after the intervention period. RESULTS: Members of the CBSM group (N = 22) showed significant improvement in cognitive coping strategies involving positive reframing and acceptance, and in social supports involving attachment, alliances, and guidance at the end of the 10-week CBSM program compared with controls (N = 18) who showed decrements in these coping abilities and no changes in social support. Improved cognitive coping, specifically acceptance of the HIV infection, was strongly related to lower dysphoria, anxiety, and total mood disturbance in both conditions. Changes in social support and in cognitive coping skills seem to mediate the effects of the experimental condition on the changes in distress noted during the intervention. CONCLUSIONS: These results suggest that cognitive coping and social support factors can be modified by psychosocial interventions and may be important determinants of the changes in psychological well-being and quality of life during symptomatic HIV infection that can be achieved through this form of intervention.

Adrenal medullary fibrosis in IDDM of long duration.

We conducted a retrospective pathology study to determine whether subjects with long-standing insulin-dependent diabetes mellitus (IDDM) have abnormalities of the adrenal medulla compared with subjects with non-insulin-dependent diabetes mellitus (NIDDM) and nondiabetic individuals. Slides were scored from 0 (no fibrosis) to 3+ (complete fibrosis). Nineteen IDDM subjects aged 30-60 yr (mean +/- SE 44.9 +/- 2.5 yr) at autopsy and with duration of diabetes 13-45 yr (26.8 +/- 1.8 yr) were studied. Twelve NIDDM subjects aged 61-84 yr (73.3 +/- 2.5 yr) with duration of diabetes 17-33 yr (22.8 +/- 1.9 yr) were studied. Twenty-two nondiabetic subjects aged 32-77 yr (53.7 +/- 2.9 yr) were studied. Four of 19 (27%) IDDM subjects had moderate to severe fibrosis compared to 1 of 12 (8.3%) NIDDM subjects and 1 of 22 (4.5%) control subjects. Thirteen of 19 (68%) IDDM subjects had a score of 1, 2, or 3 compared to 3 of 22 (13.6%) control subjects (P less than .0005). There was an association between duration of IDDM and fibrosis score (r = .46, P less than .05) and between age and fibrosis score among IDDM subjects (r = .57, P = .01). No association between age or duration of diabetes and fibrosis score was observed for NIDDM or control subjects. Adrenal medullary fibrosis may be an anatomical correlate of the diminished epinephrine secretion that occurs in response to insulin-induced hypoglycemia in some IDDM subjects.
