Objective: To determine the relationship between varicose veins and duration of menstrual life, age of menopause, pregnancy, oral contraceptive use and hormone replacement therapy (HRT). Design: Cross-sectional study. Setting: City of Edinburgh, UK. Participants: Eight hundred and sixty-seven women aged 18–64 years randomly selected from 12 general practices. Methods: After completing a questionnaire, which included questions on reproductive history, the women underwent a comprehensive clinical examination including the assessment of varicose veins (trunk, hyphenweb and reticular varices), followed by duplex scanning of their legs. Results: Women who had been pregnant at least once were more likely to have minor hyphenweb or reticular varices than women who had never been pregnant ( p ≤ 0.05). Women aged 35–54 years who were current users or ex-users of the oral contraceptive pill had a lower prevalence of trunk varicose veins than women who had never taken the pill ( p ≤ 0.10). HRT was also associated with a lower prevalence of trunk varices ( p ≤ 0.05). Conclusions: These results suggest that alterations in the balance of the sex hormones may have a role in the aetiology of varicose veins.
• Ambulatory esophageal pH monitoring, radiologic examination, endoscopy, and manometry were undertaken in 142 patients with globus. The results demonstrate that abnormal gastroesophageal reflux occurred in 23% of patients, implying that, while reflux may be responsible for globus in some patients, it is not the cause of globus sensation in the majority of individuals with this symptom. Comparing patients with globus and control subjects, there were no differences in lower esophageal sphincter pressures, esophageal body motility, or tonic upper esophageal sphincter pressures, but patients with globus exhibited higher pharyngeal and upper esophageal sphincter after-contraction pressures during deglutition. The physiological significance of this pharyngeal and upper esophageal dysmotility is not clear and it may be no more than a secondary phenomenon. Alternatively, it may contribute to the generation of globus, perhaps in combination with other physical and psychological triggers. (Arch Otolaryngol Head Neck Surg.1989;115:1086-1090)
1. Blood flow patterns are poorly understood despite their impact on arterial disease. There have been few measurements in vivo of the three-dimensional blood flow patterns; we present the results of such studies using a new non-invasive in-vivo method of examining biplanar arterial blood flow patterns. 2. Multiple colour Doppler ultrasound directional velocity images were obtained at two different beam target angles from the artery in the plane perpendicular to its axis. Ensemble average images were constructed; the absolute velocity and direction were calculated by compounding the left and right averaged images. Simple directional, non-directional velocity and vector maps were constructed. 3. Flow patterns were sampled in 11 healthy male volunteers at four points of the pulse cycle; peak systole, systolic downswing, diastolic reverse flow and diastolic forward flow and at three sites; the right common and distal superficial femoral and the left common femoral arteries. 4. Stable rotational flow was observed in all subjects, the direction of rotation varying between sides and individuals. 5. There are theoretical advantages to spiral laminar blood flow; the forward-directed, rotationally induced stability and reduction of laterally directed forces may reduce turbulence in the tapering branching arterial tree and at stenoses and have a beneficial effect on mechanisms of endothelial damage and repair.
