Re-integration into work

This is the first complete textbook designed for physiotherapists and occupational therapists on the topic of pain. It was developed for use in conjunction with the International Association for the Study of Pain's pain curriculum for OTs and PTs. The book addresses the nature of pain, the neuroanatomical and neurophysiological substrates of pain, the psychological... More aspects of pain, the lifespan approach to pain, pain measurement, pain and placebo, modalities for treating pain, and special topics in pain. It provides an overview of the physiological, psychosocial, and environmental aspects of pain experience across the lifespan. Aimed primarily at OTs and PTs the assessment and interventions issues pertaining to the perspectives of each profession are discussed in detail. The book is also relevant to the other health professions involved in pain management or intending to work in this area.

Personality traits in patients with juvenile myoclonic epilepsy

There is evidence of personality disorders in patients with juvenile myoclonic epilepsy (JME). To date, there have been no published quantitative studies on personality traits in JME. The aim of the work described here was to study a group of patients with JME and quantitatively measure personality traits. We evaluated 42 patients (mean age: 26.57 years, SD: 8.38) and 42 controls (mean age: 26.96, SD: 8.48) using a validated personality inventory, the Temperament and Character Inventory (TCI). We applied two scores, one for the Beck Depression Inventory and one for the State-Trait-Anxiety Inventory, as depression and anxiety may impact the performance of these patients on the TCI. We compared both groups on TCI scales using analysis of covariance with Beck Depression Inventory and State-Trait-Anxiety Inventory scores as covariates. Patients with JME obtained significantly higher scores on Novelty Seeking (P=0.001) and Harm Avoidance (P=0.002) and significantly lower scores on Self-Directedness (P=0.001). Patients with JME have a higher expression of impulsive personality traits that demand early recognition to avoid further consequences and facilitate social insertion, consequently avoiding future stigma.

Comparative Prevalence, Correlates of Impairment, and Service Utilization for Eating Disorders Across US Ethnic Groups: Implications for Reducing Ethnic Disparities in Health Care Access for Eating Disorders

Objective: The study compared the prevalence, correlates of functional impairment, and service utilization for eating disorders across Latinos, Asians, and African Americans living in the United States to non-Latino Whites. Method: Pooled data from the NIMH Collaborative Psychiatric Epidemiological Studies (CPES; NIMH, 2007) were used. Results: The prevalence of anorexia nervosa (AN) and binge-eating disorder (BED) were similar across all groups examined, but bulimia nervosa (BN) was more prevalent among Latinos and African Americans than non-Latino Whites. Despite similar prevalence of BED among ethnic groups examined, lifetime prevalence of any binge eating (ABE) was greater among each of the ethnic minority groups in comparison to non-Latino Whites. Lifetime prevalence of mental health service utilization was lower among ethnic minority groups studied than for non-Latino Whites for respondents with a lifetime history of any eating disorder. Discussion: These findings suggest the need for clinician training and health policy interventions to achieve optimal and equitable care for eating disorders across all ethnic groups in the United States.

Rate of occupational leg swelling is greater in the morning than in the afternoon

The aim of this study was to investigate the rate of occupational leg swelling depending on the time period of the working day Volumetric variations of the legs of 70 hospital employees, enrolled in three groups, were evaluated. Group I: 35 morning shift workers; Group II: 35 afternoon shift workers; and Group III: 15 individuals randomly selected from Groups I and II, who were evaluated on the day they worked 12 hours consecutively. Volumetry was performed before and after each shift for both legs of the participants in Groups I and II. For Group III volumetry was performed early in the morning, at noon and in the evening, For statistical analysis, the Student`s t-test and Mann-Whitney test were used with an alpha error of 5%. being considered acceptable (P value < 0.05). Significant increases in volume were recorded for the limbs in all three groups (P value < 0.001). On comparing Groups I and II, the accumulation of fluids was significantly higher in the morning than in the afternoon (P value < 0.003). Asymptomatic workers may present with oedema of the legs during their work with the rate of oedema being different for morning and afternoon shifts. The possibility of wearing compression stockings should be considered for this type of work.

ISOKINETIC EVALUATION OF PATIENTS SUBMITTED TO TOTAL KNEE ARTHROPLASTY

Objective: In total knee arthroplasty, the minimally-invasive approach has been claimed to enable earlier rehabilitation because it spares the femoral quadriceps muscle. To check the influence of preserving the extensor apparatus during surgery, the strength of knee extension and flexion muscles was evaluated in patients submitted to total knee arthroplasty with different approaches. Materials and Methods: The values of maximum torque and total work obtained by isokinetic dynamometry six months after surgery were compared for the Minimally invasive surgery group constituted of 12 individuals submitted to total knee arthroplasty by the minimally invasive surgical approach and the Control group, constituted of eight patients submitted to total knee arthroplasty by the transquadricipital approach, between January 2005 and July 2006. Results: Statistical analysis of the absolute values for maximum torque and total work adjusted for body weights did not show differences between both groups. Conclusion: There was no difference in the extension and flexion strength of the knee muscles six months after surgery.

Identification of fructooligosaccharides in different banana cultivars

Banana has been currently indicated as a good source of fructooligosaccharides (FOS), which are considered to be functional components of foods. However, significant differences in their amounts in bananas have been observed in the literature. This work aims to identify and quantify FOS during ripening in different banana cultivars belonging to the most common genomic groups cultivated in Brazil. Considering that these differences can be due to cultivar, stage of ripening, and the methodologies used for FOS analyses, sugar contents were analyzed by high performance anion exchange chromatography-pulsed amperometric detection (HPAEC-PAD) and gas chromatography-mass spectrometry (GC-MS). An initial screening of eight cultivars (Ouro, Nanicao, Prata, Maca, Mysore, Pacovan, Terra, and Figo) in a full-ripe stage showed that 1-kestose, the first member of the FOS series (amounts between 297 and 1600 mu g/g of DM), was accumulated in all of them. Nystose, the second member, was detected only in Prata cultivar. Five of the cultivars were analyzed during ripening, and a strong correlation could be established with a specific sucrose level (similar to 200 mg/g of DM), which seems to trigger the synthesis of 1-kestose (the low amounts of FOS, below the functional recommended dose, indicates that banana cannot be considered a good source of FOS).

Biomechanical effects of immobilization and rehabilitation on the skeletal muscle of trained and sedentary rats

Because of the scarcity of information about the comparison of training to sedentarism beforehand immobilization and rehabilitation through muscle mechanical properties, the present work investigates this theme. Seventy rats were divided into 7 groups: 1-control (C); 2-trained (T); 3-sedentary (S); 4-trained and immobilized (TI); 5-sedentary and immobilized (SI); 6-trained, immobilized and rehabilitated (TIR); 7-sedentary, immobilized and rehabilitated (SIR). Interventions: Swimming training; Sedentarism (reduced size cages); Cast immobilization (pelvic limb) and water rehabilitation. Load at the limit of proportionality (LLP), maximum limit load (MLL) and stiffness (St) were the mechanical properties determined after a mechanical test of traction of the gastrocnemius. The training improved all mechanical properties when compared to sedentarism. After immobilization, LLP and MLL were reduced in TI and SI. However, there was no difference in St between C and TI. Additionally, TI showed improved MLL when compared to SI. The comparison of TI and TIR showed significant melioration in all properties after remobilization. SIR showed an improvement only in MLL when compared to SI. Significant melioration in LLP and St was observed in TIR compared to SIR. We demonstrated that the training before immobilization and rehabilitation had a positive effect on the muscle mechanical behavior compared to sedentarism. This analysis is of fundamental importance because it helps characterize the muscle tissue under different functional demands.

In vitro schistosomicidal effects of some phloroglucinol derivatives from Dryopteris species against Schistosoma mansoni adult worms

The rhizomes of Dryopteris species have popularly been used as vermifuge in flatworm infections. The aim of this work was to evaluate the in vitro schistosomicidal activity of some phloroglucinol compounds, obtained from the rhizomes of Dryopteris species, against Schistosoma mansoni adult worms. All worm pairs were dead after 24 h of incubation with aspidin 25 to 100 mu M (1), flavaspidic acid 50 and 100 mu M (2), methylene-bis-aspidinol 100 mu M (3), and desaspidin 25 to 100 mu M (4). Worms incubated with 1 (25 to 100 mu M) and 2 (50 to 100 mu M) showed decrease motor activity with tegumental alterations, while 3 (100 mu M) and 4 (10 to 100 mu M) showed decrease motor activity without tegumental alterations. Desaspidinol (5) and filicinic acid (6), at the tested concentrations (10 to 100 mu M), did not show activity against adult worms of S. mansoni. Praziquantel (10 mu M), used as positive control, caused death of the parasites and tegumental alterations without separation of worms. In the groups treated with 100 A mu M of compounds 1-4, the viability of the adult worms was similar to the positive control group, in which the worms were dead. Also, both the egg productions and the development of eggs produced by the adult worms were inhibited by the incubation with compounds 1-4 (10 and 100 mu M) in comparison with the negative control (RPMI 1640 medium). It is suggested that the in vitro schistosomicidal effects of phloroglucinols derivatives 1, 2, 3, and 4 may be related to the inhibition of oxidative phosphorylation pathway in S. mansoni. The present results confirmed the traditional indications of rhizomes from Dryopteris species, which possess phloroglucinol compounds, in the treatment of tapeworm infections.

Structural evaluation of the effects of chronic ethanol ingestion on the testis of Calomys callosus

Chronic exposure to ethanol may results in pathophysiologic changes in cellular function. The present work was designed to investigate the morphology of testis submitted to experimental ethanol ingestion. Experimental animals were divided into two groups. The control group (n = 23) received a solid diet and tap water and the alcoholic group (n = 23) received the same solid diet and ethanol P.A. diluted 20% in water (v/v). After 120 days of treatment, all animals were anesthetized, weighed and sacrificed. Testosterone and luteinizing hormone levels in serum were lower in the alcoholic group than in the control group. Histological and ultrastructural alterations were observed in the testicular alcoholic germinative cells like enormous spaces, lipid droplets accumulation, digestive vacuoles, irregular diameter of the seminiferous tubules and interstitial dilated blood vessels. It was concluded that 20% ethanol provokes lesions on the testis germinative epithelium probably inducing gonadal dysfunction. (C) 2008 Elsevier Ltd. All rights reserved.

Evaluation of the respiratory muscle strength of cirrhotic patients: Relationship with Child-Turcotte-Pugh scoring system

Pulmonary abnormalities are observed in chronic hepatopathy. The measurement of the maximum inspiratory and expiratory pressure may evaluate lung function and the risks associated with hepatic transplantation. Thus, the present work sought to evaluate the respiratory muscle strength of 29 patients between 17 and 63 years old who were enrolled for liver transplantation. The patients were classified according to Child-Turcotte-Pugh score as A, B, or C, and also according to a physiotherapeutic evaluation, which included measurement of respiratory muscle strength by means of a digital manovactrometer, which determines the maximum inspiratory pressure (MaxIP) and the maximum expiratory pressure (MaxEP). The tests were performed with seated individuals having their nostrils obstructed by a nasal clip. The MaxIP was measured during the effort initiated in the residual volume, whereas the MaxEP was measured during the effort initiated in the total pulmonary capacity, keeping pressures stable for at least 1 second. The statistical analysis was performed through using the Mann-Whitney test with a 5% level of significance. The MaxIP values of Child A 95.5 +/- 40.507 cm H2O (average +/- DP) and Child B 87.2 +/- 35.02 patients were higher than those for Child C patients (34.83 +/- 3.68; P <.05). Similar results were observed for the MaxEP of Child A and B groups (116.25 +/- 31.98 and 97.28 +/- 31.08, respectively; P <.05), versus the Child C group (48.16 +/- 22.60). Between groups A and B, the MaxEP were similar (P >.05). We concluded that Child C patients display muscle weakness significantly greater than that of subjects classified as Child A or B.
