A retrospective study was carried out between 2006-2011. Six hundred and eighteen patients with suspected allergic contact dermatitis underwent the standard patch test series recommended by the Brazilian Contact Dermatitis Research Group. The aim of our study was to evaluate the variation of positive patch-test results from standard series year by year. The most frequently positive allergens were: nickel sulfate, thimerosal and potassium bichromate. Decrease of positive patch-test results over the years was statistically significant for: lanolin (p=0.01), neomycin (p=0.01) and anthraquinone (p=0.04). A follow-up study should be useful in determining which allergens could be excluded from standard series, as they may represent low sensitization risk. © 2013 by Anais Brasileiros de Dermatologia.

Cervical spondylotic myelopathy is a well-known cause of disability among older people. A significant amount of these patients is asymptomatic. Once the symptoms start, the worsening may follow a progressive manner. We should suspect of spondylotic myelopathy in any individual over 55 years presenting progressive changes in gait or losing fine motor control of the upper limbs. Despite its frequent prevalence, this condition is still neglected and many times confused with other supratentorial lesions regarding diagnostic. Here we address some of most important aspects of this disease, calling attention to pathophysiology, the natural history, presentation, differential diagnosis, clinical assessment, and treatment.

Leprosy Review | Year: 2011
Disability caused by leprosy may be associated with stigma. The aim of this work is to describe the degree of disability, quality of life and level of physical activity of individuals with leprosy and to identify possible correlations between these factors. Ninety-seven patients from two referral centres were studied. A complete medical history was taken and the World Health Organization degree of physical disability classification (WHO-DG), the International Physical Activity Questionnaire (IPAQ) and the Medical Outcome Study 36-item Short-form health Survey (SF36) were applied. The mean age of patients was 51 ± 14·9 years old; participants were predominantly men, married, unemployed, had concluded treatment and had had lepromatous leprosy. The WHO-DG and the level of physical activity (P-value = 0·36) were not correlated. The WHO-DG showed that 72·2% of patients had disabilities, 37·1% of whom performed vigorous physical activities. No significant association was observed between the WHO-DG and the domains of the QoL SF-36 except for functional capacity (P-value = 0·02); the physical capacity is generally 'very good' when individuals have no disabilities and 'bad' with severe disabilities. In conclusion, the WHO-DG of leprosy patients does not affect the level of physical activities or quality of life except functional capacity. There is no significant association between physical activities and quality of life in these individuals. © Lepra.

BACKGROUND: One of the dreaded complications after the treatment of breast cancer is lymphedema. Therapies used in the treatment of breast cancer such as surgery, radiotherapy, hormone therapy and chemotherapy may be adversely affected by obesity. AIM: The objective of this study was to use bioimpedance to assess abdominal fat in women with breast cancer treatment-related lymphedema and suggest this as a screening method. METHODS: Forty-five female patients with clinical diagnosis of breast cancer treatment-related lymphedema were evaluated in this quantitative cross-sectional study. A control group, composed of 38 patients with varicose veins and women attending a social support group, was matched for age and body mass index (BMI). All participants were submitted to a bioimpedance evaluation (In Body S 10), with particular attention being paid to abdominal fat and their BMI. The unpaired t-test, Fisher Exact test and Mann Whitney test were used for statistical analysis and an alpha error of 5%. RESULTS: There was no significant difference (p-value = 0.23) in the mean BMI between the study group (27:79 kg=m2) and the control group (28:80 kg=m2). The mean abdominal circumference, a measure of abdominal fat, of the women in the study group was 130:54 cm2 and for the control group it was 102:24 cm2 (p-value = 0.0037). Thus the study group had more abdominal fat (p-value = 0.0003). Moreover, on comparing obese patients in the two groups, the study group had more abdominal fat (p-value = 0.02). However, no significant difference was observed comparing non-obese patients (p-value = 0.6). The comparison of obese patients with non-obese patients in the control group identifies an association between obesity and abdominal fat (p-value 0.04). CONCLUSION: Overweight and obese women with breast cancer treatment-related lymphedema are more likely to have increased abdominal fat than the general population with bioimpedance. © 2016 IOS Press and the authors.

PURPOSE: To determine whether a hypercaloric and hyperlipidic diet enriched with polyunsaturated fatty acids infuences the formation of aberrant crypt foci (ACF) in colonic mucosa of Wistar rats treated with azoxymethane (AOM).METHODS: At eight weeks of life, the rats were assigned to four groups: Group I-standard diet (STD) not treated with AOM; Group II-hypercaloric and hyperlipidic diet (FED), not treated with AOM; Group III-STD, treated with AOM; Group IV-FED, treated with AOM. At 16 weeks, the animals were injected intraperitoneal with 0.9% saline solution (Group I and II) or AOM at 15mg/Kg (Groups III and IV) once a week for two weeks. Fifteen weeks later, the animals were euthanized.RESULTS: FED promoted weight gain in Groups II and IV compared to Groups I and III, respectively. The groups did not differ with regard to the total number of ACF. The Chi-square test revealed no predominance of the presence of foci with ≤4 crypts. However, foci with ≥5 crypts were proportionally more prevalent in Group III than in Group IV (p=0.043).CONCLUSION: The administration of polyunsaturated fatty acids did not interfere with the formation of aberrant crypt foci, but reduced ACF multiplicity, exercising an attenuating effect on carcinogenesis.

Molecules of animal or bacterial origin, which pose a risk for zoonoses or immune rejection, are commonly used for extraction, culture, and cryopreservation of mesenchymal stem cells. There is no sequentialandorderly protocol for producinghumanadipose-derivedstemcells (hASCs) under xeno-free conditions. After standardizing a humanplatelet lysate (hPL) production protocol, four humanadipose tissue samples were processed through explants with fetal bovine serum (FBS)-supplemented or hPLsupplemented media for extracting the adipose-derived stem cells. The cells were cultivated in cell culture medium + hPL (5%) or FBS (10%). The cellular replication rate, immunophenotype, and differentiation potential were evaluated at fourth passage. Cellular viability was evaluated before and after cryopreservation of the cells, with an hPL-based solution compared with an FBS-based solution. The explants cultured in hPL-supplemented media showed earlier and faster hASC proliferation than did those supplemented with FBS. Likewise, cells grownin hPL-supplementedmedia showeda greater proliferation rate, without losing the immunophenotype. Osteogenic differentiation of xeno-free hASC was higher than the hASC produced in standard conditions. However, adipogenic differentiation was reduced in xeno-free hASC. Finally, the cells cryopreserved in an hPL-based solution showed a higher cellular viability than the cells cryopreserved in an FBS-based. In conclusion,wehave developed a complete xeno-free protocol for extracting, culturing, and cryopreserving hASCs that can be safely implemented in clinical studies. © AlphaMed Press 2016.

The case of a rare complication is reported of a 53-year-old patient with giant polycystic kidney (4250 g) that evolved with acute small bowel occlusion. The patient was submitted to surgery which identified that the intestinal occlusion was due to external compression of the intestinal loops. Excision of the mass solved the case.

A randomized controlled trial was performed to evaluate the effect of the combination of compression therapy with active exercising using a facilitating apparatus on arm lymphedema.Twenty women with a mean age of 63.3 years were evaluated; all had lymphedema resulting from breast cancer treatment. The inclusion criterion was a difference of 200 mL in size between arms. The apparatus used, called pulley system, is a vertical iron wheel fixed on a support at a distance of 10 cm from the patients body. Participants were submitted to two series of active exercises using this facilitating device, one series using a compression sleeve and the other without. Each series consisted of four 12-minute sessions of exercises separated by 3-minute rest intervals. Volumetry was performed before and after each series of exercises. The paired t-test was utilized for statistical analysis (p-value < 0.05).A significant mean reduction (p-value < 0.007) and non-significant mean increase (p-value < 0.2) in volumes were observed during exercising with and without compression, respectively.Controlled active exercising utilizing a facilitating apparatus while wearing a compression sleeve reduces the size of lymphedematous arms.

Objective. The aim of this study was to evaluate the bone healing after the usage of a scaffold enriched with bone marrow. Study Design. Ten rabbits were divided into 2 groups of 5 animals. Bilateral 12mm diameter defects were created in the parietal bones. In control group Bio-Oss were inserted in both defects and, in experimental group, Bio-Oss enriched with autologous bone marrow were inserted in both defects. In these two groups, one of the calvarial defects was covered with Bio-Gide. The rabbits were sacrified 8 weeks after surgery and both CT and histomorphometric analysis were done. Results. The CT showed a lower remaining defect area in the experimental group covered with Bio-Gide when compared with control group, with and without Bio-Gide. The histomorphometrics showed no difference between groups regarding the non-vital mineralized tissue area. For vital mineralized tissue area, the experimental group covered with Bio-Gide obtained a higher percentage area when compared with control group, with and without Bio-Gide. For non-mineralized tissue area, the experimental group covered with Bio-Gide obtained a lower percentage area when compared with control group, with and without Bio-Gide. Conclusion. Both autologous bone marrow and membrane can contribute to the enhancement of bone healing.
