The effect of varying humidity and dry bulb temperatures was studied on five normal male unclothed subjects while exercising (40-45 min) at 28% VO2max. Air movement was 0.75 m.s-1. The initial test and the 16th test on each subject both done at 50 degrees C and 30 Torr (32% rh). Each subject did the intervening 14 experiments twice per day at varying ambient temperature (Ta) and water vapor pressure (Pa) levels, so selected to progressively increase skin wettedness levels. Mean skin temperature (Tsk) and esophageal temperature (Tes), heart rate (HR), skin evaporative heat loss (Esk), and warm discomfort were continuously observed. Skin wettedness (w) was evaluated as the ratio of the observed Esk to the maximum evaporative capacity of the environment. A rational effective temperature (ET) is defined as the dry bulb temperature at 50% rh in which the total heat exchange from skin surface would be the same as in the test environment, described by the observed Ta and Pa. The results showed that 1) during steady state both HR and Tes were unaffected by Ta from 26 to 41 degrees C responding to the level of exercise intensity, when Pa less than or equal to 20 Torr; 2) both mean body temperature, found by weighting Tsk:Tes by 1:9, and ET were each significant indicators of physiological strain when Pa greater than 20 Torr; 3) a level of strain, caused by skin wettedness values greater than 0.5, is suggested as a primary condition necessary for inducing heat acclimation.

Prolonged immobilization in an upright position often leads to discomfort and oedema in the feet of otherwise healthy subjects. To determine the significance of leg activity and ambient pressure on oedema formation, skin temperature (Tsk) and discomfort, 6 volunteers sat for 8 h with one leg immobilized and the other spontaneously active; one day at "sea level" (750 mmHg) and one day at reduced barometric pressure (540 mmHg). Foot swelling was measured by water plethysmography. Leg movements were continuously monitored by a Vitalog computer, and foot discomfort was estimated by analog-visual scales. The 8 hour swelling averaged 5.7% in the inactive foot, and 2.7% in the active foot (p less than 0.001). Tsk of the inactive foot levelled off towards ambient temperature (21 degrees C) within 4 h. For the active foot this fall was reduced by 2-3 degrees C (p less than 0.025). The increase in foot discomfort during the day was lowest in the active foot (p less than 0.005). High foot Tsk was associated with a high foot swelling rate. Reduced ambient barometric pressure had no effects on foot swelling or Tsk. It is concluded that modest leg activity during 8 h of sitting has several effects on the circulation in the feet: some effects promote and some prevent oedema formation. However, the net result is a reduction in foot swelling.

Seventy-one patients with symptoms of colorectal disease were evaluated with the rigid 25-cm sigmoidoscope and an inexpensive 35-cm flexible proctosigmoidoscope (American Optical FPS-2) to determine if the latter is a diagnostically reliable alternative for routine sigmoidoscopy. Examination time was comparable, 3.6 min for the rigid and 4.2 min for the flexible sigmoidoscope. Average insertion length was 21 cm for the rigid and 29.5 cm for the flexible instrument. Forty-two patients had more discomfort during the rigid versus nine during the flexible examination. Significant lesions were documented in eight patients with the rigid and 13 with the flexible sigmoidoscope. One rectal carcinoma and seven polyps were detected with both instruments, while an additional nine polyps were documented only with the flexible instrument. The 35-cm flexible proctosigmoidoscope may be a feasible alternative for routine sigmoidoscopy.

A conflict was contrived between thermal and non-thermal drives in humans to study the effects of varying degrees of voluntary suppression of behavioral temperature regulation. Five, young, near-nude males were paid 2, 5, 10, 20 or 40 cents per min to expose themselves to increasing cold (15 degrees to 0 degree C in 2 hours), after being instructed to terminate the exposure as soon as the cold discomfort exceeded the monetary reward. The duration of voluntary cold exposure was approximately linearly related to the logarithm of monetary reward. Reported cold discomfort was greater with high than with low rates of reward. Although V02 approached summit metabolism, the capacity for shivering did not appear to limit cold tolerance. Subjects adopted various strategies for coping with the conflict but, in general, greatest cold tolerance was recorded in subjects of large body mass and willing to tolerate low Tsk.

Two experiments examined the influences of endurance training and heat acclimation on ratings of perceived exertion (RPE) and thermal discomfort (RTD) during exercise in the heat while wearing two types of clothing. In experiment 1, young men underwent 8 weeks of physical training [60-80% of maximal aerobic power (VO2max) for 30-45 min day-1, 3-4 days week-1 at 20-22 degrees C dry bulb (db) temperature] followed by 6 days of heat acclimation [45-55% VO2max for 60 min day-1 at 40 degrees C db, 30% relative humidity (rh)] (n = 7) or corresponding periods of control observation followed by heat acclimation (n = 9). In experiment 2, young men were heat-acclimated for 6 or 12 days (n = 8 each). Before and after each treatment, subjects completed bouts of treadmill exercise (1.34 m s-1, 2% grade in experiment 1 and 0% grade in experiment 2) in a climatic chamber (40 degrees C db, 30% rh), wearing in turn normal light clothing (continuous exercise at 37-45% VO2max for a tolerated exposure of 116-120 min in experiment 1 and at 31-34% VO2max for 146-150 min in experiment 2) or clothing protective against nuclear, biological, and chemical agents (continuous exercise at 42-51% VO2max for a tolerated exposure of 47-52 min in experiment 1 and intermittent exercise at 23% VO2max for 97-120 min in experiment 2). In experiment 1, when wearing normal clothing, endurance training and/or heat acclimation significantly decreased RPE and/or RTD at a fixed power output. There were concomitant reductions in relative work intensity (% VO2max) [an unchanged oxygen consumption (VO2) but an increased VO2max, or a reduced VO2 with no change of VO2max], rectal temperature (Tre), mean skin temperature (Tsk), and/or heart rate (HR). When wearing protective clothing, in contrast, there were no significant changes in RPE or RTD. Although training and/or acclimation reduced %VO2max or Tre, any added sweat that was secreted did not evaporate through the protective clothing, thus increasing discomfort after training or acclimation. Tolerance times were unchanged in either normal or protective clothing. In experiment 2, when wearing normal clothing, heat acclimation significantly decreased RPE and RTD at a fixed power output, with concomitant reductions in Tre, Tsk, and HR; the response was greater after 12 than after 6 days of acclimation, significantly so for RPE and HR. When wearing protective clothing, the subjects exercised at a lower intensity for a longer duration than in the moderate exercise trial. Given this tactic, either 6 or 12 days of heat acclimation induces significant reductions RPE and/or RTD, accompanied by reductions in Tre, Tsk, and/or HR. Tolerance times in protective clothing were also increased by 11-15% after acclimation, despite some increase of sweat accumulation in the protective clothing. The results suggest that (1) neither endurance training nor heat acclimation reduce psychological strain when protective clothing is worn during vigorous exercise, because increased sweat accumulation adds to discomfort, and (2) in contrast to the experience during more vigorous exercise, heat acclimation is beneficial to the subject wearing protective clothing if the intensity of effort is kept to a level that allows permeation of sweat through the clothing. This condition is likely to be met in most modern industrial applications.

Our aim was to determine country-specific attitudes and perceptions of patients with genital warts and to understand the psychosexual impact of the disease and its treatment. We used a standardized discussion guide to interview patients with genital warts in Canada, France, Germany, the UK, and the USA about their perceptions and concerns regarding the diagnosis, treatment, and psychosexual impact of the disease. Interviews were conducted in person and lasted approximately 30 min. The study group included 80 men and 86 women with genital warts. Forty-seven per cent were currently undergoing treatment. Overall, 49% of the men had first consulted a general or family practitioner, and 52% of the women had first consulted a gynaecologist. Although all the patients eventually consulted a physician about their warts, one-third delayed seeing a doctor because they thought the condition would resolve on its own or that the problem was not serious. Most patients reported that treatment was associated with pain, discomfort, and embarrassment. Sixty per cent of patients experienced a recurrence after initial clearance with treatment. More than 80% stated that they had had little or no involvement in the selection of treatment. Globally, 52% of men and 61% of women were 'quite concerned' or 'very concerned' about having genital warts, although there were significant variations by country. Approximately two-thirds of patients had made lifestyle changes regarding sexual relationships. In addition, two-thirds believed that there were risks associated with having genital warts; the most common risk identified was a link to cancer (cervical and unspecified). A high level of anxiety is associated with the diagnosis and treatment of genital warts. Patients with genital warts require understanding and an acknowledgement of their concerns. A better understanding of the psychosexual aspect of the disease by health-care providers is pivotal to effective disease management and patient counselling.

In response to a need to match drug users to the most appropriate and cost-effective level of care, it was hypothesized the socially anxious methadone-maintained patients would attain greater benefit from coping skills training provided in the context of a low-intensity enhanced standard methadone maintenance intervention (E-STD) than in the context of a high-intensity, socially demanding day treatment program (DTP). Social anxiety was assessed in 307 methadone-maintained patients using the Social Anxiety and Distress Scale prior to randomization to either E-STD or DTP. The hypothesis was supported: Socially anxious patients were drug free longer during treatment, were more likely to be abstinent at treatment completion, and had greater reductions in HIV risk behaviors if assigned to the lower intensity intervention, which was provided at 1/3 the cost of the DTP.

STD treatment choices and perceptions of treatment services (access, quality of care) by Zimbabwean men are examined in 2 settings: Mbare, a district within the capital city Harare, and Gutu, a rural town. Data collection included a survey of 457 men 18 years of age or older (from a stratified systematic sample), focus groups and key informant interviews. Of 220 cases of self-reported genital symptoms, 81.4% were treated by allopathic practitioners, 9% by traditional/faith healers, 8.6% by the subject, a friend or another person; 1.4% were not treated. Traditional/faith healers were consulted primarily for symptoms involving pain or discomfort rather than ulcers or exudation. Disrespect by the health care provider and consultations that were not private were cited as problems by a small minority of subjects. Significantly more respondents in Mbare than in Gutu had been prevented from obtaining the STD treatment they desired at some point in their life because of cost of treatment (chi(2)=5.23, P=0.02). Given the current deteriorating economic situation in Zimbabwe, cost of treatment may become an even more important impediment in the future.

Genital warts are usually asymptomatic, and rarely cause discomfort. Once the patient is aware of them the main symptom is their cosmetic appearance and resultant psychological consequences. The ideal treatment outcome would be complete viral eradication, but this is not possible. Treatments focus on the removal of exophytic warts, leaving the surrounding subclinical and latent human papillomavirus (HPV) infection as areas of possible transmission and recurrence. Effective treatment does reduce HPV viral load, so the infection is reduced if not completely eradicated. Treatment is often painful, inconvenient, and may produce poor clearance rates and frequent recurrences. The treatment chosen should be no worse or more dangerous than the disease itself, and should be tailored to the patients' disease and needs as well as to the available resources. Genital warts are highly infectious and sexual partners may well already be infected when a patient presents for treatment. There are no published studies showing that condom use reduces transmission of HPV from people with genital warts. However, if the sexual partner is uninfected; using a condom may protect against HPV lesions and genital warts. Condom use should be encouraged in new relationships.

The effects of bathroom thermal conditions on physiological and subjective responses were evaluated before, during, and after whole-body bath (W-bath), half-body bath (H-bath) and showering. The air temperature of the dressing room and bathroom was controlled at 10 degrees C, 17.5 degrees C, and 25 degrees C. Eight healthy males bathed for 10 min under nine conditions on separate days. The water temperature of the bathtub and shower was controlled at 40 degrees C and 41 degrees C, respectively. Rectal temperature (Tre), mean skin temperature (Tsk), blood pressure (BP), heart rate (HR), body weight loss and blood characteristics (hematocrit: Hct, hemoglobin: Hb) were evaluated. Also, thermal sensation (TS), thermal comfort (TC) and thermal acceptability (TA) were recorded. BP decreased rapidly during W-bath and H-bath compared to showering. HR during W-bath was significantly higher than for H-bath and showering (p < 0.01). The double products due to W-bath during bathing were also greater than for H-bath and showering (p < 0.05). There were no distinct differences in Hct and Hb among the nine conditions. However, significant differences in body weight loss were observed among the bathing methods: W-bath > H-bath > showering (p < 0.001). W-bath showed the largest increase in Tre and Tsk, followed by H-bath, and showering. Significant differences in Tre after bathing among the room temperatures were found only at H-bath. The changes in Tre after bathing for H-bath at 25 degrees C were similar to those for W-bath at 17.5 degrees C and 10 degrees C. TS and TC after bathing significantly differed for the three bathing methods at 17.5 degrees C and 10 degrees C (TS: p < 0.01 TC: p < 0.001). Especially, for showering, the largest number of subjects felt "cold" and "uncomfortable". Even though all of the subjects could accept the 10 degrees C condition after W-bath, such conditions were intolerable to half of them after showering. These results suggested that the physiological strains during H-bath and showering were smaller than during W-bath. However, colder room temperatures made it more difficult to retain body warmth after H-bath and created thermal discomfort after showering. It is particularly important for H-bath and showering to maintain an acceptable temperature in the dressing room and bathroom, in order to bathe comfortably and ensure warmth.
