Systematic review on the impact of exercise on intraocular pressure in glaucoma patients.

Due to limited studies, we systematically reviewed evidence on the impact of physical exercise on intraocular pressure (IOP) in glaucoma patients, adhering to PRISMA guidelines. Using MEDLINE/Web of Science, PubMed, and Scopus, we selected English, Portuguese, or Spanish studies excluding case reports and yoga-based interventions. From 1001 records, 15 studies were independently evaluated. Evaluated through the MMAT scoring system, two quantitative randomised controlled studies scored 100% while 13 non-randomised studies averaged 84.62%. Our findings indicated that both aerobic and resistance training led to an immediate IOP reduction post-exercise. However, these findings were largely from single-session experiments. In contrast, the effects of longer-term exercise programmes on IOP varied. Although our review underscores the potential utility of exercise in IOP management, the evidence remains inconclusive due to variations in study design, participant demographics, and exercise parameters. This lack of consistency in the research highlights the necessity for larger, standardised, and longer-term studies to robustly corroborate these preliminary findings.

[Unilateral thalamotomy with high intensity focal ultrasound in patients with refractory essential tremor: a comparative study between patients under and over 70 years of age]. / Talamotomía unilateral con ultrasonidos focales de alta intensidad en pacientes con temblor esencial refractario: un estudio comparativo entre pacientes menores y mayores de 70 años.

INTRODUCTION: High intensity focal ultrasound (HIFU) thalamotomy is a novel treatment for refractory tremor. This study aims to compare the reduction in tremor intensity and adverse effects of treatment between patients younger and older than 70 years of age. PATIENTS AND METHODS: All the patients with refractory essential tremor treated with HIFU between March 2021 and March 2023 were included consecutively. Various demographic and clinical variables were analysed, including age and the items on the Clinical Rating Scale for Tremor (CRST). Cerebral vascular pathology was quantified using the Fazekas scale. Outcomes and adverse effects were compared between the patients aged 70 years or younger, and those older than 70 years. RESULTS: Ninety patients were included, and 50 of them were over 70 years old. Prior to treatment, the CRST A + B score was 20.4 ± 5.7 among those under 70 years of age, and 23.3 ± 5.1 in those older (p = 0.013). At six months after treatment, the mean was 3.8 ± 5.1 and 4.8 ± 4.5, respectively (p = 0.314). We found no significant differences in the CRST C score (2.8 ± 4.1 and 3.5 ± 4.8, p = 0.442). There were also no significant differences between the patients with vascular pathology (Fazekas = 1) and those without (4.6 ± 7.3 and 4.3 ± 4, p = 0.832). There were no differences in the presence of adverse effects between the groups based on age and vascular pathology. CONCLUSIONS: Contrary to traditional opinion, older patients do not have a poorer response or a higher rate of adverse effects after HIFU treatment.

TITLE: Talamotomía unilateral con ultrasonidos focales de alta intensidad en pacientes con temblor esencial refractario: un estudio comparativo entre pacientes menores y mayores de 70 años.Introducción. La talamotomía con ultrasonidos focales de alta intensidad (HIFU) es un tratamiento novedoso para el temblor refractario. El objetivo de este estudio es comparar la reducción en la intensidad del temblor y los efectos adversos del tratamiento entre pacientes menores y mayores de 70 años. Pacientes y métodos. Se incluyó consecutivamente a todos los pacientes con temblor esencial refractario tratados con HIFU entre marzo de 2021 y marzo de 2023. Se analizaron diferentes variables demográficas y clínicas, incluyendo la edad y los apartados de la Clinical Rating Scale for Tremor (CRST). Se cuantificó la patología vascular cerebral mediante la escala de Fazekas. Se compararon los resultados y los efectos adversos entre los grupos de edad de 70 años o menos y de más de 70 años. Resultados. Se incluyó a 90 pacientes, 50 de ellos de más de 70 años. Previamente al tratamiento, la CRST A + B era de 20,4 ± 5,7 en los menores de 70 años y de 23,3 ± 5,1 en los mayores (p = 0,013). A los seis meses tras el tratamiento, la media fue de 3,8 ± 5,1 y 4,8 ± 4,5, respectivamente (p = 0,314). No hallamos diferencias significativas en la CRST C (2,8 ± 4,1 y 3,5 ± 4,8, p = 0,442). Tampoco hubo diferencias significativas entre pacientes con patología vascular (Fazekas = 1) y sin ella (4,6 ± 7,3 y 4,3 ± 4, p = 0,832). No hubo diferencias en la presencia de efectos adversos entre los grupos de edad y de patología vascular. Conclusiones. En contra de lo tradicionalmente concebido, los pacientes de mayor edad no tienen una peor respuesta ni una mayor tasa de efectos adversos tras el tratamiento con HIFU.

Physical activity in Parkinson's disease: examining prescription sources, patterns, and the influence of quality of life and disease severity. / La actividad física en la enfermedad de Parkinson: identificación de los responsables de su prescripción, hábitos e impacto en la calidad de vida, y de la gravedad de la enfermedad.

INTRODUCTION: Limited research has explored the influence of quality of life (QoL) and disease severity on physical activity (PA) in Parkinson's disease (PD) patients, and the sources of PA prescription and advice for this population. This study aims to expand scientific knowledge on these topics. PATIENTS AND METHODS: Two-hundred eleven PD patients were personally interviewed to collect data on PA levels using the International Physical Activity Questionnaire-Short Form and QoL using the Parkinson's Disease Questionnaire-8. An ad hoc questionnaire gathered information on disease severity (Hoehn and Yahr stages), PA behaviors, and PA recommendations. RESULTS: Weak but significant associations were found between PA levels, disease severity (r: -0.218; p = 0.004), and QoL (r: -0.244; p = 0.001). Most participants (85%) received PA counselling, predominantly from neurologists, either at diagnosis (52%) or shortly after (28%). Before PD onset, ~86% engaged in PA, decreasing to 66% post-diagnosis. Approximately 78% reported changes in PA, including reduced frequency (18.4%) and duration (32.8%), with walking as the primary activity. CONCLUSIONS: Disease severity and QoL significantly affect PA levels in PD patients. Diagnosis is associated with decreased PA frequency and duration, and walking is the preferred activity. Neurologists primarily provide PA advice.

TITLE: La actividad física en la enfermedad de Parkinson: identificación de los responsables de su prescripción, hábitos e impacto en la calidad de vida, y de la gravedad de la enfermedad.Introducción. Escasas investigaciones han explorado la influencia de la calidad de vida (CV) y la gravedad de la enfermedad en la actividad física (AF) en pacientes con enfermedad de Parkinson (EP), así como las fuentes de prescripción de AF y consejos para esta población. Este estudio tiene como objetivo ampliar el conocimiento científico sobre estos temas. Pacientes y métodos. Se entrevistó personalmente a 211 pacientes con EP para recopilar datos sobre los niveles de AF con el International Physical Activity Questionnaire-Short Form y la CV con el Parkinson's Disease Questionnaire-8. Un cuestionario ad hoc recopiló información sobre la gravedad de la enfermedad (etapas de Hoehn y Yahr), los comportamientos de AF y las recomendaciones de AF. Resultados. Se encontraron asociaciones débiles, pero significativas, entre los niveles de AF, la gravedad de la enfermedad (r = ­0,218; p = 0,004) y la CV (r = ­0,244; p = 0,001). La mayoría de los participantes (85%) recibió asesoramiento sobre AF, principalmente de neurólogos, ya sea en el momento del diagnóstico (52%) o poco después (28%). Antes del inicio de la EP, ~86% participaba en AF, lo que disminuyó al 66% después del diagnóstico. Aproximadamente el 78% informó sobre cambios en la AF, incluida una reducción en la frecuencia (18,4%) y la duración (32,8%), y la caminata era la actividad principal. Conclusiones. La gravedad de la enfermedad y la CV afectan significativamente a los niveles de AF en pacientes con EP. El diagnóstico se asocia con una disminución en la frecuencia y la duración de la AF, y la caminata es la actividad preferida. Los neurólogos aconsejan principalmente sobre AF a las personas con EP.

Reliability and criterion-related validity of the Cooper test in pre-adolescents and adolescents: A systematic review and meta-analysis.

The Cooper test (CT) is used to assess cardiorespiratory fitness (CRF) in pre-adolescents and adolescents, although it was originally developed to assess healthy adults. The aim of this study is to examine the available scientific evidence on the reliability and criterion validity of CT when administered to pre-adolescents and adolescents. Systematic searches were performed in three electronic databases (MEDLINE/PubMed, SPORTDiscuss and Scopus). To examine reliability and validity, four separate meta-analyses were implemented, finding high heterogeneity in studies with low methodological quality. There was a paucity of research regarding absolute reliability, while studies attempting to develop or cross-validate VO2max/VO2peak equations were almost non-existent. Information on the psychometric properties of CT in pre-adolescents under 12 years of age is scarce. The findings of this review cast doubt on the usefulness of CT both in identifying CRF and in determining the impact of strategies developed to improve CRF among pre-adolescents and adolescents.

Prevalence and severity of urinary incontinence among male and female competitors and recreational CrossFit® practitioners.

OBJECTIVE: This study aimed to determine the prevalence, severity and type of urinary incontinence (UI) in female and male CrossFit® practitioners. STUDY DESIGN: The study design is an online cross-sectional survey distributed to CrossFit® practitioners across all Spanish regions. The questionnaire included categorical questions related to CrossFit® practice, multiple-choice questions to determine the exercises performed during reported UI symptoms, and The International Consultation on Incontinence Questionnaire Short-Form questionnaire items. RESULTS: Five hundred seventy-one practitioners (34.0 ± 8.37 years, Body Mass Index 24.20 ± 3.34 kg/m2) met inclusion criteria and completed the survey. There were and 316 females and 255 males. Around 45 % of women and 6 % of men reported having UI (p < 0.001). The severity of UI mainly was slight (30.3 % women, 3.5 % men) and moderate (11.7 % women, 2.3 % men) (p < 0.001). Stress and urgent UI were the most prevalent types among women (36 %) and men (5 %) (p < 0.001). CONCLUSIONS: This study found that UI is relatively common among female CrossFit® practitioners, especially in repetitive jumps. The practitioners' profile (amateur/competitor) does not affect the prevalence or severity of UI. Male athletes can also experience urine leakage while performing CrossFit®, although its prevalence is much lower when compared to female practitioners.

Feasibility and reliability of the Functional Movement Screen battery in adults with intellectual disability.

BACKGROUND: The feasibility and reliability of the Functional Movement Screen (FMS) battery for predicting injury risk have been widely studied in athletic, military, public service and healthy populations. However, scant research has been carried out in people with disabilities. This study aimed at identifying the feasibility and reliability of the FMS battery when administered to adults with intellectual disability (ID). METHODS: Adults from a residential and day care centre over 18 years of age, diagnosed with ID and able to follow simple instructions, were included in the study. All participants with behavioural or health problems that prevented the completion of the FMS battery were excluded. All exercises were video recorded to assure proper scoring. Three assessors (one trained and two novices) scored each of the FMS subtests performed separately from the videos. Feasibility was based on completion rates. Reliability of the composite test scores was analysed using intraclass correlation coefficients (ICCs). RESULTS: A total of 30 people with ID (mean age: 35.5 ± 7.12 years; 33.3% women) completed all assessments. The battery showed to be feasible, although difficulties when performing two of the subtests were observed among those with moderate and severe ID. Mean total scores from the three assessors ranged from 7.83 to 8.90. An inverse trend was observed indicating that the higher the ID level, the lower the total FMS score. Test-retest reliability was good for the trained assessor (ICC = 0.89) and mostly moderate for both novice assessors (ICC range: 0.60 to 0.76). Moderate to good inter-rater reliability was observed (ICC range: 0.65 to 0.80). CONCLUSION: The FMS battery is a reliable tool that can be performed by people with ID, albeit with certain difficulties, especially in those with moderate to severe impairment. The battery does not seem to be useful for identifying people with ID at risk of suffering a sport injury. Adequately powered, well-designed studies are required to determine if the FMS battery is appropriate for identifying changes in functional performance in this population.

[Reliability and validity of the SAPF questionnaire and the Stunkard rating scale amongst elderly Spanish people].

BACKGROUND: The aim of the study was to identify the reliability and validity of the SAPF questionnaire and the Stunkard rating scale in determining self-perceived physical appearance and the degree of body dissatisfaction in a group of elderly Spanish people. METHODS: Both instruments were adapted to Spanish people and were administered twice to a group of 86 elderly people. Their reliability and validity were assessed by means of the intraclass correlation coefficient (ICC), Cronbach's alpha and Spearman's rho coefficient, from the physical fitness level of the participants and their body mass index (BMI). ANOVA test was carried out to compare the variables with normal distribution. RESULTS: The questionnaire and the Stunkard rating scale showed a good test-retest reliability (ICC=0.78 and ICC=0.8, respectively). SAPF and fitness level showed a significant, albeit weak, association (rho=0.424), while the association between self-perception of body composition and BMI was moderately strong (rho=0.727). The self-perceived physical appearance of 59.5% of the sample was acknowledged to be normal, 11.4% perceived it as bad and 29.1% as good. Only 27.1% were satisfied with their body image, while the other participants showed a desire to lose the equivalent weight of one (47.06%), two (22.35%) or three or more (3.5%) points in the Stunkard scale. CONCLUSION: The versions of both instruments adapted to Spanish persons showed reliability and validity, and showed that it was possible to determine that a large part of the sample was dissatisfied with their body image. BMI had a significant influence in this regard.

Influence of Frailty Status on Pain, Disability, and Quality of Life in Older Adults with Acute Low Back Pain: Results from the Back Complaints in the Elders (BACE-Brazil) Study.

A cross-sectional analysis was conducted using data from a prospective cohort study to investigate whether frailty is associated with pain intensity, disability caused by low back pain (LBP), and quality of life in an older population with acute non-specific LBP. Six hundred and two individuals with a mean age of 67.6 (standard deviation [SD] 7.0) years were included in the analysis. In relation to frailty status, 21.3 per cent of the sample were classified as robust, 59.2 per cent were classified as pre-frail, and 19.5 per cent were classified as frail. In the unadjusted analysis, pre-frail and frail groups showed significantly higher pain and disability scores than the robust group. Moreover, the same two groups exhibited lower scores in both physical and mental domains of quality of life than the robust group. After adjusting for socio-demographic and clinical variables, disability scores and the physical component of quality of life were significantly associated with frailty. In older adults with acute LBP, frailty is associated with more disability and worse scores in the physical component of quality of life.

[Analysis of the convergent validity of the Spanish short version of the Minnesota Leisure Time Physical Activity Questionnaire (VREM) and the Spanish version of the International Physical Activity Questionnaire in elderly people (IPAQ-E)]. / Análisis de la validez convergente de la Versión reducida en español del cuestionario de actividad física en el tiempo libre de Minnesota (VREM) y de la versión española del Cuestionario internacional de actividad física en personas mayores (IPAQ-E).

BACKGROUND: In our country the Spanish short version of the Minnesota Leisure Time Physical Activity Questionnaire (VREM) and the International Physical Activity Questionnaire in elderly people (IPAQ-E) are considered useful tools for estimating the amount of physical activity (PA) performed by the geriatric population. However, few studies have been carried out on their psychometric properties. Therefore, this research aims to provide information on their convergent validity by analysing the degree of association that both questionnaires show with physical fitness level. MATERIAL AND METHODS: A total of 105 people (mean age: 76.77 (SD=6.01) years; 84.8% women), answered both questionnaires and performed the Senior Fitness Test (SFT), in order to assess their physical fitness level. RESULTS: Significant correlations were found between the SFT and the VREM items related to energy expenditure derived from walking (r=0.227) or from performing sports activities or dancing (r=0.235), and the estimated total energy expenditure (r=0.314). The IPAQ-E did not establish significant associations with any of the variables analysed. Although a certain a priori correlation was observed between the VREM and the IPAQ-E (r=0.447, p<0.001) and the mean difference between both parameters was nil (p=0.553), it was considered that the questionnaires showed a lack of agreement due to the great width found in the range of differences. CONCLUSIONS: The use of the VREM questionnaire is recommended for estimating the amount of PA performed by the geriatric population, as it shows a certain degree of association, albeit weak, with the level of physical fitness.

Lipid changes and tolerability in a cohort of adult HIV-infected patients who switched to rilpivirine/emtricitabine/tenofovir due to intolerance to previous combination ART: the PRO-STR study.

Objectives: To analyse lipid changes and tolerability in a cohort of HIV-infected patients who switched their antiretroviral regimens to rilpivirine/emtricitabine/tenofovir (RPV/FTC/TDF) in a real-world setting. Methods: PRO-STR is a 48 week prospective observational post-authorization study in 25 hospitals. Patients with a viral load <1000 copies/mL, receiving at least 12 months of combination ART (cART), with constant posology for at least the prior 3 months, were categorized according to previous treatment [NNRTI or ritonavir-boosted PI (PI/r)]. Analytical tests were performed at the baseline visit, between week 16 and week 32, and at week 48. Results: A total of 303 patients were included (mean age 46.6 years; male 74.0%; previous treatment 74.7% NNRTI and 25.3% PI/r). Both groups exhibited significantly reduced lipid profiles, except for HDL cholesterol, for which a non-significant increase was observed. [NNRTI patients: total cholesterol (baseline: 195.5 ±âŸ38.4 mg/dL; week 48: 171.0 ±âŸ35.5 mg/dL), total cholesterol/HDL ratio (baseline: 4.2 ±âŸ1.2; week 48: 4.0 ±âŸ1.2), HDL (baseline: 49.1 ±âŸ12.0 mg/dL; week 48: 49.2 ±âŸ45.8 mg/dL), LDL (baseline: 119.2 ±âŸ30.2 mg/dL; week 48: 114.2 ±âŸ110.7 mg/dL), and triglycerides (baseline: 136.6 ±âŸ86.8 mg/dL; week 48: 113.4 ±âŸ67.8 mg/dL); PI/r patients: total cholesterol (baseline: 203.2 ±âŸ48.8 mg/dL; week 48: 173.4 ±âŸ36.9 mg/dL), total cholesterol/HDL ratio (baseline: 4.7 ±âŸ1.6; week 48: 4.0 ±âŸ1.2), HDL (baseline: 46.4 ±âŸ12.5 mg/dL; week 48: 52.1 ±âŸ54.4 mg/dL), LDL (baseline: 127.0 ±âŸ36.3 mg/dL; week 48: 111.4 ±âŸ35.8 mg/dL), and triglycerides (baseline: 167.6 ±âŸ107.7 mg/dL; week 48: 122.7 ±âŸ72.1 mg/dL)]. The most common intolerances were neuropsychiatric in the NNRTI patients and gastrointestinal and metabolic in the PI/r patients, and these intolerances were significantly reduced in both groups at week 48 [NNRTI: neuropsychiatric (baseline: 81.3%; week 48: 0.0%); PI/r: gastrointestinal (baseline: 48.7%; week 48: 0.0%) and metabolic (baseline: 42.1%; week 48: 0.0%)]. Conclusions: RPV/FTC/TDF improved the lipid profiles and reduced the intolerances after switching from NNRTI or PI-based regimens, in a cohort of HIV-infected patients.

Modelling of composting process of different organic waste at pilot scale: Biodegradability and odor emissions.

The composting process of six different compostable substrates and one of these with the addition of bacterial inoculums carried out in a dynamic respirometer was evaluated. Despite the heterogeneity of the compostable substrates, cumulative oxygen demand (OD, mgO2kgVS) was fitted adequately to an exponential regression growing until reaching a maximum in all cases. According to the kinetic constant of the reaction (K) values obtained, the wastes that degraded more slowly were those containing lignocellulosic material (green wastes) or less biodegradable wastes (sewage sludge). The odor emissions generated during the composting processes were also fitted in all cases to a Gaussian regression with R2 values within the range 0.8-0.9. The model was validated representing real odor concentration near the maximum value against predicted odor concentration of each substrate, (R2=0.9314; 95% prediction interval). The variables of maximum odor concentration (ouE/m3) and the time (h) at which the maximum was reached were also evaluated statistically using ANOVA and a post-hoc Tukey test taking the substrate as a factor, which allowed homogeneous groups to be obtained according to one or both of these variables. The maximum oxygen consumption rate or organic matter degradation during composting was directly related to the maximum odor emission generation rate (R2=0.9024, 95% confidence interval) when only the organic wastes with a low content in lignocellulosic materials and no inoculated waste (HRIO) were considered. Finally, the composting of OFMSW would produce a higher odor impact than the other substrates if this process was carried out without odor control or open systems.

Analysis of pharmacodynamic interaction of sevoflurane and propofol on Bispectral Index during general anaesthesia using a response surface model.

BACKGROUND: Propofol and sevoflurane act on the GABA(A) receptor, modulating the function of this receptor in an additive manner. The pharmacodynamic interaction of both drugs considering their effect on EEG activity analysed by the bispectral index (BIS) was identified as additive, but this has not been studied in a clinical setting. The objective of this study was to analyse the pharmacodynamic interaction of propofol and sevoflurane on BIS using a surface response model in patients undergoing general anaesthesia with i.v. induction and inhalation maintenance. METHODS: We performed a prospective study in 24 patients undergoing general anaesthesia with propofol induction and sevoflurane maintenance. Anaesthetic depth was measured with a BIS VISTA Bilateral monitor. Propofol biophase concentration was determined using a three-compartment pharmacokinetic model, and sevoflurane end-tidal concentration was measured continuously. The response surface model described by Minto and colleagues was used to analyse the interaction. Statistical analysis was performed with Excel 2002 and SPSS v11.0. RESULTS: The mean value of U(50)(theta) was 0.956 (sd 0.029) in the overall estimated data, and remained within the predefined range for all ratios of the drugs, fulfilling the criterion of additivity. The median of the weighted residuals between the actual BIS value and the BIS value predicted by the model was -5.926%. CONCLUSIONS: Under the study conditions, it was confirmed that sevoflurane and propofol have an additive effect on BIS, with no evidence suggesting the existence of a synergistic effect for the concentrations of both drugs typically used in clinical practice.

Comparative study of topical anaesthesia with lidocaine 2% vs levobupivacaine 0.75% in cataract surgery.

BACKGROUND: This study compared the efficacy of topical anaesthesia with levobupivacaine 0.75% vs lidocaine 2% during cataract surgery by phacoemulsification. METHODS: A prospective, randomized, double-blind study comparing two agents for topical anaesthesia in cataract surgery. Two hundred and forty-six consecutive patients undergoing corneal phacoemulsification were enrolled into two groups to receive either topical levobupivacaine 0.75% (n=126) or lidocaine 2% (n=120). The main outcome variables of the study were intraoperative and postoperative pain, requirement for additional anaesthesia, patient comfort and cooperation, surgeon satisfaction, and corneal epithelial toxicity induced by topical drugs. RESULTS: evobupivacaine 0.75% provided significantly better analgesia than lidocaine 2% during cataract surgery (P<0.001) at the end of surgery (P<0.002), and up to 30 min after surgery (P<0.001). There were no statistically significant differences between the two groups 5 h after surgery. Epithelial toxicity was similar in both groups, and patient comfort and surgeon assessment of patient cooperation were better in the levobupivacaine group. CONCLUSIONS: Topical anaesthesia with levobupivacaine 0.75% was more effective than lidocaine 2% in preventing pain and improving patient and surgeon comfort during cataract surgery, with similar toxicity.

[Aortopulmonary fistula complicating aortic arch aneurysm]. / Fistula aorto-pulmonar como complicación de aneurisma de cayado aórtico.

Aortopulmonary fistulas secondary to thoracic aneurysms are difficult to diagnose and few cases are reported in the literature. We describe the case of a patient first admitted to another hospital with a diagnosis of right upper lobe pneumonia. After the patient had been a week in hospital without improving, a computed tomography scan of the chest revealed a saccular aneurysm of the aortic arch measuring 9 cm at its widest diameter. Hemodynamics and respiratory signs deteriorated a few hours after transfer to our hospital. Physical examination revealed a systolic murmur and poor peripheral perfusion. The patient was intubated and inotropic support was provided. Upon insertion of a Swan-Ganz catheter, given suspicion of septic shock, progressive elevation of mixed venous oxygen saturation was observed. Measurement of venous oxygen saturation was 74% in the right atrium and 93% in the pulmonary artery. Left-right shunt was diagnosed and an emergency aortography revealed the aortopulmonary fistula. Emergency surgery was performed with the patient in deep hypothermia and cardiocirculatory arrest. There were no adverse events, and postoperative recovery and clinical course were good.

[Prevalence of urinary incontinence in the population aged more than 64 years in Galicia, Spain]. / Prevalencia de la incontinencia urinaria en personas mayores de 64 años en Galicia.

OBJECTIVE: To determine the prevalence of urinary incontinence in the Galician population aged more than 64 years. METHODS: We performed a descriptive study, based on a personal interview with each individual from a sample of the target population. The sample was obtained through random sampling stratified into urban, semi-urban and rural of the Autonomous Community of Galicia. Subsequently, a random sample was extracted from the database of the individual health cards of selected localities. A total of 350 interviews in 12 sampling locations were performed. RESULTS: The prevalence of urinary incontinence in Galicia in 2002 was 35.14% (95% CI: 31-38%, 15-28 for men and 38-51% for women). CONCLUSIONS: One out of three Galicians aged more than 64 years presents urinary incontinence. The prevalence is almost double in women.

Granulomatous amebic encephalitis in a patient with AIDS: isolation of acanthamoeba sp. Group II from brain tissue and successful treatment with sulfadiazine and fluconazole.

A patient with AIDS, treated with highly active antiretroviral therapy and trimethoprim-sulfamethoxazole, presented with confusion, a hemifield defect, and a mass lesion in the right occipital lobe. A brain biopsy confirmed granulomatous amebic encephalitis (GAE) due to Acanthamoeba castellanii. The patient was treated with fluconazole and sulfadiazine, and the lesion was surgically excised. This is the first case of AIDS-associated GAE responding favorably to therapy. The existence of a solitary brain lesion, absence of other sites of infection, and intense cellular response in spite of a very low CD4 count conditioned the favorable outcome. We review and discuss the diagnostic microbiologic options for the laboratory diagnosis of infections due to free-living amebae.

Reciprocating tachycardia during central venous cannulation in a patient with Wolff-Parkinson-White syndrome.

Wolff-Parkinson-White syndrome is important for the anesthesiologist because the sudden development of tachyarrhythmias may result in deleterious hemodynamic changes. We describe an episode of reciprocating tachycardia triggered by the insertion of the guide wire during central venous cannulation in a patient with this syndrome.
