Are women with urogenital atrophy symptomatic?

OBJECTIVE: The purpose of this study was to determine the degree of correlation between physical signs of genital atrophy and symptoms that are suggestive of atrophic vaginitis. STUDY DESIGN: Female volunteers (n = 135; mean age, 69 years) rated the presence and severity (rating, 0-3) of vaginal atrophy symptoms. The presence and severity of vaginal mucosal changes, which included vaginal pH (0-3), were recorded during a pelvic examination. A vaginal cytologic maturation value was performed. Symptoms, signs, pH, and maturation value were correlated by the Spearman rank test. RESULTS: Symptom scores were low (mean, 0.41; range, 0-2.6). Symptoms were only weakly correlated with physical findings (r = 0.14) and not with maturation value (r = 0.06) or age (r = -0.004). There was a moderate correlation between physical examination score and maturation value (r = -0.48). In women > or =65 years old, symptom score and physical examination score were correlated weakly (r = 0.25). Low pH correlated well with high maturation value (r = -0.52). Women who were undergoing estrogen therapy had higher symptoms scores (P =.0007) and maturation values (P =.0002) than women who were not undergoing therapy. CONCLUSION: Although urogenital atrophy occurs universally after menopause, most elderly women are minimally symptomatic. Those women on estrogen replacement therapy may be more symptomatic. Symptoms alone should not be used as a guide for the initiation of estrogen therapy.

Design and synthesis of semicarbazones and their bio-isosteric analogues as potent anticonvulsants: the role of hydrogen bonding.

A series of p-nitrophenyl substituted semicarbazones (4a-c) and phenoxy/p-bromophenoxy acetyl hydrazones (8a-q) were synthesized and their anticonvulsant activity was screened against maximal electroshock seizure (MES), subcutaneous metrazole (ScMet) and subcutaneous strychnine (ScSty) tests. Compounds 4a-c with -NHCO- were found to be the most active in all these tests. These compounds were also active in the MES test after oral administration in rats. On the other hand, compounds 8a-q with -OCH2- were devoid of anticonvulsant activity. The studies revealed that the hydrogen bonding domain in semicarbazones, adjacent to the lipophilic aryl ring, is essential for the anticonvulsant activity.

Choline ingestion does not modify physical or cognitive performance.

OBJECTIVES: This study was undertaken to determine whether choline ingestion improves physical and cognitive performance following exhaustive load carriage exercise. METHODS: In a double-blind crossover study, 13 men (28 +/- 2 years) underwent four test sessions: load carriage treadmill and no-load carriage test sessions after taking choline or placebo. Physical and cognitive performance batteries were administered at the end of the test sessions. RESULTS: Choline ingestion (50 mg/kg body weight) significantly (p < 0.05) increased plasma choline concentrations during the load and no-load carriage test sessions. However, plasma choline did not decrease during the placebo load carriage test session, an indication that load carriage does not deplete circulating choline. There were no differences in performance on physical tasks, and choline ingestion had no effect on reaction time, logical reasoning, vigilance, spatial memory, or working memory. CONCLUSION: In healthy men, supplemental choline did not affect physical or cognitive performance after exhaustive physical activity.
