OBJECTIVE To identify the prevalence of hyperhidrosis among medical students of Manaus, State of Amazonas, Brazil. METHODS We conducted an observational, transversal, survey which examined the prevalence of primary hyperhidrosis among medical students of the Federal University of Amazonas and its relation to body mass index (BMI) and stress. Students were weighed and interviewed. We used questionnaires with questions recommended by the International Hyperhidrosis Society to relate hyperhidrosis to the daily activities of each person. Results were given by calculating the prevalence ratios and confidence intervals. RESULTS Among the 293 students examined, it was found that a total of 16 (5.5%) students had barely tolerable or intolerable excessive sweating, interfering with daily activities. None had known causes of hyperhidrosis and 50% had family history. In all suffering from the condition the disease was bilateral, the mainly affected locations being: hands (35.7%), legs (21.4%), axilla (17.9), face (10 7%), back (7.1%), chest (3.6%) and abdomen (3.6%). There was no predominance regarding gender, age or BMI. We found a positive relationship with BMI and observed a prevalence ratio of 2.48 higher in overweight students than in normal weight or underweight ones. CONCLUSION The prevalence of primary hyperhidrosis among medical students of Manaus was 5.5%. There is a positive non-statistical relationship with overweight and obesity. It was further noted an observational relationship with stress.

OBJECTIVE: To evaluate the type and prevalence of incidental findings from cone beam computed tomography (CBCT) of the maxillofacial region. Findings are divided into those that require (i) intervention/referral,(ii) monitoring, and (iii) no further evaluation. METHODS: Three hundred consecutive CBCT scans conducted in the University of North Carolina School of Dentistry Oral and Maxillofacial Radiology Clinic from January 1 to August 31, 2008 were retrospectively reviewed. Findings were categorized into airway, soft tissue calcifications, bone, temporomandibular joint (TMJ), endodontic, dental developmental, and pathological findings. RESULTS: A total of 272 scans revealed 881 incidental findings (3.2 findings/scan). The most prevalent was airway findings (35%) followed by soft tissue calcifications (20%), bone (17.5%), TMJ (15.4%), endodontic (11.3%), dental developmental (0.7%), and pathological (0.1%). 16.1% required intervention/referral, 15.6% required monitoring, and the remainder (68.3%) required neither. CONCLUSION: This study underscores the need to thoroughly examine all CBCT volumes for clinically significant findings within and beyond the region of interest.

A systematic review of evidence of the effectiveness of educational and supportive strategies for enabling caregivers of people with Alzheimer's disease (AD) or related dementias to maintain participation in that role was conducted as part of the American Occupational Therapy Association's Evidence-Based Literature Review Project. Forty-three articles met inclusion criteria. Results suggest that interventions that jointly engage people with AD and their caregivers in education and training in the home setting are more successful than strategies that focus solely on people with AD. Greater carryover is noted when education and training are implemented at the time that the caregiver identifies concerns. Interventions should provide caregivers with problem solving, technical skills, support, simple home modification strategies, and referral to community resources. Interventions mediated by technology have a positive effect on the caregiver and are especially important for those who live in rural areas.

A systematic review was conducted to determine the effectiveness of interventions to prevent falls in people with Alzheimer's disease (AD) and related dementias. Twelve research reports met inclusion criteria. Studies reported on three types of intervention:(1) exercise- and motor-based interventions,(2) nursing staff-directed interventions, and (3) multidisciplinary interventions. Strategies were offered as single or multifaceted intervention programs. All types of intervention resulted in benefit, although the evidence for effectiveness is tentative because of the studies' limitations. More research is needed to better understand appropriate dosages of intervention. No evidence was found for the effectiveness of prevention programs accessed as part of occasional respite care. Occupational therapy was seldom involved in the interventions researched. Because effective fall prevention programs are embedded in people's daily routines and encouraged participation in occupation, the contribution occupational therapy practitioners can make to the care of people with AD has yet to be fully realized.

A systematic review of evidence for the effectiveness of modification of activity demands in the care of people with Alzheimer's disease (AD) was conducted as part of the American Occupational Therapy Association's Evidence-Based Literature Review Project. The review included 10 articles addressing occupations of self-care and leisure. No reports related to work and social participation were located. Results suggest that evidence for this intervention's effectiveness is strong. Four practice principles were derived from this appraisal:(1) Occupational therapy programs should be individualized to elicit the person's highest level of retained skill and interest,(2) cues used while assisting people with AD to complete tasks should be short and provide clear direction,(3) compensatory strategies in the form of environmental modifications and simple adaptive equipment should be specifically implemented on the basis of the unique needs of the person, and (4) caregiver training and involvement are essential in implementing individualized programs.

A systematic review of evidence for the efficacy of environment-based interventions on the affect, behavior, and performance of people with Alzheimer's disease and related dementias was conducted as part of the American Occupational Therapy Association's Evidence-Based Literature Review Project. Thirty-three reports met inclusion criteria. Results suggest that ambient music, aromatherapy, and Snoezelen are modestly effective in reducingagitation but do not consistently have long-term effects. Visually complex environments that give the illusion of barriers deter people from wandering to unsafe places but do not reduce the urge to wander. Evidence that bright light therapy can aid in regulating mood and the sleep-wake cycle and thus help people remain awake during the day is preliminary. Montessori-based programming can be useful in matching activities to the person's remaining skills. Further research is needed to evaluate the long-term effect, contraindications, and best dosages of these interventions.

BACKGROUND: Low functional health literacy has been related to poor viral control, and lower levels of ART adherence in people living with HIV/AIDS. Research in functional health literacy among people living with HIV/AIDS in Puerto Rico (PR) is an unexplored area. The purpose of this paper is to describe how the full-length Spanish Version of the Test of Functional Health Literacy in Adults (TOFHLA-S) scale was adapted to PR. METHODS: Thirty participants (women = 16, men = 14) completed a basic demographic questionnaire, the TOFHLA-S and participated in an interview. Analyses were performed to examine the information provided by participants and the internal consistency of the TOFHLA-S. RESULTS: The mean age was 47.7 years (range 34-77). Thirty-seven percent had less than 12 years of formal schooling and 43% reported having education above high school. Changes suggested by participants included: increasing font size from 14 to 16 points for better readability and changes/simplification of several words in order to make them colloquial and comprehensible for the PR context. The reliability coefficient obtained for this scale was strong (estimated alpha = 0.95) however, differences were observed by subtype: numeracy (estimated alpha(num)=.819 vs. comprehension (estimated alpha =. 953). CONCLUSIONS: Based on this process, we have adapted the original version of the TOFHLA-S and the new version of the full-length TOFHLA-S, PR is now valid for further research and testing levels of functional health literacy in a larger sample in PR.
