Presenting Symptoms and Diagnosis of Vulvar Lichen Sclerosus in Premenopausal Women: A Cross-Sectional Study.

OBJECTIVES/PURPOSE: Presenting symptoms of vulvar lichen sclerosus (LS) specific to premenopausal women are not well reported in the literature and may differ from those in postmenopausal women. This study aimed to characterize the presentation of vulvar LS among premenopausal women. MATERIALS AND METHODS: An observational web-based study was conducted in premenopausal women with biopsy-confirmed vulvar LS between the ages of 18-50 years. Participants completed a 28-question survey evaluating characteristics of symptoms, timing of diagnosis, alternate diagnoses, and presence of concomitant autoimmune conditions. RESULTS: Of the 956 responses received, 503 met inclusion criteria of biopsy-confirmed LS and premenopausal status. Average age of symptom onset was 27 years, and average age of diagnosis was 32 years, with a 4-year delay in diagnosis. Symptoms most present were dyspareunia (68%) and tearing with intercourse or vaginal insertion (63%). Symptoms that affect the individual most were also dyspareunia (44%) and tearing with intercourse or vaginal insertion (39%). Symptoms that most frequently prompted patients to seek medical attention were dyspareunia (35%), pruritus (31%) and tearing with intercourse or vaginal insertion (26%). Most common skin changes included hypopigmentation (81%), vulvar fissures (72%), and labial resorption (60%), with fissures affecting the individual the most (48%). Sixty-six percent of the respondents initially received an alternative diagnosis, most commonly vulvovaginal yeast infection (49%). Hypothyroidism was the most common concurrent autoimmune condition (10%). CONCLUSIONS: Vulvar LS affects premenopausal women, commonly presenting with dyspareunia and tearing with intercourse. This condition should be considered and evaluated in premenopausal women presenting with vulvar symptoms and sexual pain.

Repeated restraint stress exposure during early withdrawal accelerates incubation of cue-induced cocaine craving.

A major challenge for treating cocaine addiction is the propensity for abstinent users to relapse. Two important triggers for relapse are cues associated with prior drug use and stressful life events. To study their interaction in promoting relapse during abstinence, we used the incubation model of craving and relapse in which cue-induced drug seeking progressively intensifies ('incubates') during withdrawal from extended-access cocaine self-administration. We tested rats for cue-induced cocaine seeking on withdrawal day (WD) 1. Rats were then subjected to repeated restraint stress or control conditions (seven sessions held between WD6 and WD14). All rats were tested again for cue-induced cocaine seeking on WD15, 1 day after the last stress or control session. Although controls showed a time-dependent increase in cue-induced cocaine seeking (incubation), rats exposed to repeated stress in early withdrawal exhibited a more robust increase in seeking behavior between WD1 and WD15. In separate stressed and control rats, equivalent cocaine seeking was observed on WD48. These results indicate that repeated stress in early withdrawal accelerates incubation of cocaine craving, although craving plateaus at the same level were observed in controls. However, 1 month after the WD48 test, rats subjected to repeated stress in early withdrawal showed enhanced cue-induced cocaine seeking following acute (24 hours) food deprivation stress. Together, these data indicate that chronic stress exposure enhances the initial rate of incubation of craving during early withdrawal, resulting in increased vulnerability to cue-induced relapse during this period, and may lead to a persistent increase in vulnerability to the relapse-promoting effects of stress.
