RESUMO

INTRODUCTION: Granulomatous cheilitis is a rare disorder characterized by recurrent, idiopathic, and painless lip swelling. The diagnosis is proven by histopathological examination. The unknown aetiology and poorly understood underlying mechanism contribute to the difficulty in establishing an effective treatment. This case study proposes the effectiveness of radiofrequency therapy in the management of refractory granulomatous cheilitis. CASE SUMMARY: A 68-year-old patient presented with hypertrophy and swelling of the lower lip, and a biopsy revealed actinic cheilitis. The patient underwent lip shaving and an advancement mucosal flap, and definitive histologic examination confirmed the diagnosis of granulomatous cheilitis. No other signs of orofacial granulomatosis were observed, and the complementary aetiological study was negative for systemic disease. The lip swelling reappeared and persisted, which interfered with the quality of life. Hence, radiofrequency therapy was performed in the submucosal and subdermal layers of the lip, resulting in significant aesthetic and functional improvement and no further relapses after five years. DISCUSSION: The management of granulomatous cheilitis is challenging. The current mainstay treatment is corticotherapy or reduction cheiloplasty in severe cases. Radiofrequency has potential as a treatment option in debilitating macrocheilia, presenting worthy long-lasting functional and aesthetical results, with minimal morbidity.

RESUMO

PURPOSE: To present a national guideline for ophthalmologic care and surveillance of juvenile idiopathic arthritis-associated uveitis (JIA-uveitis). METHODS: Review article based on medical literature and the experience of an Expert Committee composed of members of the Brazilian Society of Pediatric Ophthalmology/Brazilian Council of Ophthalmology and the Brazilian Society of Pediatrics/Brazilian Society of Rheumatology. Studies with a high level of evidence were selected by searching the PubMed/Medline database. The final document was approved by the experts. RESULTS: The main recommendations are that children/adolescents with JIA should undergo screening according to their risk factors. Ophthalmological checkups should also consider ocular inflammation and therapy. Topical glucocorticoids should be the first line of therapy, with systemic glucocorticoids acting as bridge treatments in severe uveitis. Methotrexate should be the first-line systemic therapy and anti-tumor necrosis factor (anti-TNF alpha) the second for uncontrolled uveitis. CONCLUSIONS: This evidence-based guideline for JIA-uveitis will be useful for both ophthalmology and rheumatology practice.

RESUMO

BACKGROUND: Hepatitis C virus (HCV) infection is responsible for a chronic liver inflammation, which may cause end-stage liver disease and hepatocellular carcinoma. Apolipoprotein E (protein: ApoE, gene: APOE), a key player in cholesterol metabolism, is mainly synthesized in the liver and APOE polymorphisms may influence HCV-induced liver damage. AIM: To determine whether APOE alleles affect outcomes in HCV-infected patients with liver cirrhosis following orthotopic liver transplantation (OLT). METHODS: This was a cohort study in which 179 patients, both genders and aged 34-70 years, were included before or after (up to 10 years follow-up) OLT. Liver injury severity was assessed using different criteria, including METAVIR and models for end-stage liver disease. APOE polymorphisms were analyzed by quantitative real-time polymerase chain reaction. RESULTS: The APOE3 allele was the most common (67.3%). In inflammation severity of biopsies from 89 OLT explants and 2 patients in pre-transplant, the degree of severe inflammation (A3F4, 0.0%) was significantly less frequent than in patients with minimal and moderate degree of inflammation (≤ A2F4, 16.2%) P = 0.048, in patients carrying the APOE4 allele when compared to non-APOE4. In addition, a significant difference was also found (≤ A2F4, 64.4% vs A3F4, 0.0%; P = 0.043) and (A1F4, 57.4% vs A3F4, 0.0%; P = 0.024) in APOE4 patients when compared to APOE3 carriers. The fibrosis degree of the liver graft in 8 of 91 patients and the lack of the E4 allele was associated with more moderate fibrosis (F2) (P = 0.006). CONCLUSION: Our results suggest that the E4 allele protects against progression of liver fibrosis and degree of inflammation in HCV-infected patients.

RESUMO

This study was performed to evaluate the linear and volumetric effects of a technique for reconstruction of the posterior atrophic mandible, including the final bone gain of the graft, by three-dimensional assessment. Thirteen individuals were recruited into the study and submitted to a total of 15 mandibular autogenous bone block surgeries. Cone beam computed tomography images were obtained at three different times. Bone graft length and thickness, and the volume, height, and width of the graft were measured. Data were compared statistically among the time points using the Friedman test, and cluster analysis was performed to identify the association between the study variables and the resorption rate (α = 0.05). Linear analysis of the width and height of the recipient area at the different time points revealed a statistically significant difference. The final average increase in height was 1.6 mm; all subjects showed an average volume gain of 3.412mm3, and 77% of the subjects showed an average graft resorption of 0.688mm3 construction of three-dimensional vertical defects of the posterior mandible resulted in good healing with minimal complications and minimal bone graft resorption, favouring vertical bone gain.

RESUMO

BACKGROUND: The incidence rates of melanoma have risen to worrying levels over the last decade. Delayed diagnosis, due to faults on the detection stage, indicates the necessity of new aiding diagnosis techniques. Since metabolic activity is highly connected to neoplasia formation, a detection technique that focuses its results on vascular responses, as Infrared thermal (IRT), seems to be a viable option. MATERIALS AND METHODS: Static and dynamic (cooling) thermal images of melanoma and melanocytic nevi lesions were collected and analysed to retrieve thermal parameters characteristic of this skin lesion types. The steady-state and dynamic variables were tested separately with different machine learning classifiers to verify whether the distinction of melanoma and nevi lesions was achievable. RESULTS: The differentiation of both types of skin tumours was doable, achieving an accuracy of 84.2% and a sensitivity of 91.3% with the implementation of a learner based on support vector machines and an input vector composed by static variables. CONCLUSION: The use of IRT for skin tumour classification is achievable, but some improvement is needed to raise the metrics of sensitivity and specificity. For future work, it is recommended the study of dynamic parameters for the classification of other types of skin neoplasia.

RESUMO

BACKGROUND: Infrared thermal imaging captures the infrared radiation emitted by the skin surface. The thermograms contain valuable information, since the temperature distribution can be used to characterize physiological anomalies. Thus, the use of infrared thermal imaging (IRT) has been studied as a possible medical tool to aid in the diagnosis of skin oncological lesions. The aim of this review is to assess the current state of the applications of IRT in skin neoplasm identification and characterization. METHODS: A literature survey was conducted using the reference bibliographic databases: Scopus, PubMed and ISI Web of Science. Keywords (thermography, infrared imaging, thermal imaging and skin cancer) were combined and its presence was verified at the title and abstract of the article or as a main topic. Only articles published after 2013 were considered during this search. RESULTS: In total, 55 articles were encountered, resulting in 14 publications for revision after applying the exclusion criteria. It was denoted that IRT have been used to characterize and distinguish between malignant and benign neoplasms and different skin cancer types. IRT has also been successfully applied in the treatment evaluation of these types of lesions. CONCLUSION: Trends and future challenges have been established to improve the application of IRT in this field, disclosing that dynamic thermography is a promising tool for early identification of oncological skin conditions.

RESUMO

Objetivou-se avaliar os efeitos do pneumoperitônio e da posição de Trendelenburg sobre o fluxo de saída do ventrículo esquerdo em gatos anestesiados. Quatorze gatos foram alocados aleatoriamente em dois grupos, ambos submetidos ao pneumoperitônio com 10mmHg de dióxido de carbono (CO2). No grupo controle (GC n=7), os animais foram submetidos apenas ao pneumoperitônio e, no grupo Trendelenburg (GTREN n=7), os animais foram colocados em cefalodeclive 20° após o pneumoperitônio. A indução anestésica foi realizada com isoflurano, utilizando-se caixa de indução. Posteriormente, os animais foram mantidos sob anestesia inalatória com o mesmo fármaco. Foram avaliados a velocidade do fluxo de saída do ventrículo esquerdo (VFSVE), os gradientes máximo (GmáxSVE) e médio (GmédSVE) de pressão e a integral velocidade-tempo (IVT). Os parâmetros foram mensurados nos momentos T0 (basal), antes da insuflação; T5 (cinco), T15 (quinze) e T30 (trinta) minutos após a insuflação. Os resultados mostraram um aumento da VFSVE no GC, em T15 e T30 (P=0,024), e um aumento do GmáxSVE no GC, em T30 (P=0,045). As variáveis não se alteraram significativamente em nenhum momento no GTREN. Dessa forma, conclui-se que a posição de Trendelenburg favoreceu o sistema cardiovascular, preservando os índices de fluxo sanguíneo na saída do ventrículo esquerdo.(AU)


The aim of this study was to evaluate the effects of pneumoperitoneum and Trendelenburg position on the left ventricular outflow in anesthetized cats. Fourteen cats were randomly divided into two groups, both submitted to pneumoperitoneum of 10 mmHg with carbon dioxide (CO2), and in the control group (GC n = 7) the animals were subjected only to pneumoperitoneum and the Trendelenburg group (n = 7 GTREN) the animals were placed in cefalodeclive 20° after pneumoperitoneum. Anesthesia of the animals was performed with isoflurane using induction box, keeping the animals under inhalation anesthesia with the same drug. We evaluated the speed of the left ventricular outflow (VFSVE), the maximum pressure gradient (GmáxSVE), mean pressure gradient (GmédSVE) and velocity-time integrals (IVT). The parameters were measured in time, T0 (baseline), before the insufflation; T5 (five); T15 (fifteen) and T30 (thirty) minutes after inflation. The results showed an increase in VFSVE in GC, T15 and T30 (p = 0,024) and an increase in GmáxSVE in GC in T30 (p = 0,045). The variables did not change significantly at any time in GTREN. Thus, it is concluded that the Trendelenburg position favored the cardiovascular system, preserving blood flow rates in the left ventricular outflow.(AU)

RESUMO

The strangles is an infectious disease that affects horses from all ages and causes important economic losses in the equine-related business. The aim of this work was to evaluate the immunogenicity of the recombinant M protein from Streptococcus equi (rSeM) co-administered with the recombinant heat-labile enterotoxin B subunit from Escherichia coli (rLTB) in mice and horses. A total of 72 female Balb-c mice were divided into eight groups and 18 horses were divided into six groups. The animals were inoculated by intramuscular (IM) or intranasal (IN) routes with different treatments of rSeM, rLTB and/or Al(OH)3. The results obtained in both species, independent of administration routes, demonstrated that rSeM + rLTB had higher levels of specific serum immunoglobulins, however, in mucosal immunity the increase was not identified. Thus, the use of rSeM as vaccine antigen and rLTB as adjuvant can be a potential tool in the control of equine strangles.(AU)

RESUMO

OBJECTIVE: The aim of this study was to investigate the clinical performance and to validate the Lesion Activity Assessment (LAA) in conjunction with the International Caries Detection and Assessment System (ICDAS) for occlusal caries diagnosis in permanent teeth. METHODS: Patients with erupted or partially erupted third molars were recruited from the surgery clinic of the School of Dentistry of the Universidade Federal de Minas Gerais, Brazil. A calibrated examiner evaluated 49 teeth using the ICDAS-LAA criteria. The histologic criterion proposed by Ekstrand and others was used to validate severity at the thresholds D1 (outer half of the enamel), D2 (inner half of the enamel and outer third of the dentin), and D3 (inner or middle third of the dentin). Lesion activity was validated using 0.1% methyl red solution. RESULTS: The method demonstrated good reliability (weighted kappa for severity=0.60; unweighted kappa for activity=0.61). The ICDAS presented a higher performance for lesion detection (area under the receiver operating characteristic curve [Az]=0.79) using the threshold D3. At the thresholds D1 and D2, the results for Az were 0.57 and 0.74, respectively. Regarding the ICDAS-LAA, Az = 0.59. CONCLUSIONS: Clinical protocols can use ICDAS for the severity diagnosis of occlusal caries, but the LAA performance was poor.

RESUMO

RESUMO O presente trabalho teve como objetivo investigar o potencial inseticida de óleos essenciais de Croton heliotropiifolius, Croton pulegiodorus, Myracrodruon urundeuva e Ocimumbasilicum sobre adultos de Tribolium castaneumem milho armazenado. Para cada óleo foram realizados bioensaios de fumigação, repelência e o efeito sobre a taxa instantânea de crescimento (ri), em cinco concentrações (0; 5; 10; 15 e 20 μL). Os bioensaios foram conduzidos sob condições constantes de temperatura (28±2 ºC), umidade relativa (70±5%) e escoto fase de 24 horas. Nos testes de fumigação diferentes concentrações dos óleos foi aplicado em tiras de papel filtro presas na parte inferior da tampa da câmara de fumigação (1,5L), a qual continha 20 gramas de substrato alimentar e 10 insetos adultos de T. castaneum não sexados. A mortalidade dos insetos foi avaliada após 48 horas de exposição. Os testes de repelência foram efetuados em arenas compostas por dois frascos ligados a uma caixa central. Em um frasco foi depositado o substrato alimentar com diferentes concentrações do óleo essencial, e, no outro, foi depositado apenas alimento (testemunha). Dez insetos adultos foram liberados na caixa central, ficando expostos por 5 dias para avaliação da preferência. Nos bioensaios de fumigação observou-se atividade inseticida do óleo essencial de M. urundeuva sobre adultos de T. castaneum. Nos bioensaios de repelência, todos os óleos testados apresentaram efeito repelente. A emergência de T. castaneumreduziu entre 33 e 100% quando foram criados em pó de milho tratado com os óleos essenciais. Os óleos essenciais de C. pulegiodorus e O. basilicum ocasionaram redução do crescimento populacional de T. castaneum em grãos de milho tratados. Os óleos testados demonstraram ser uma alternativa eficiente de controle para o uso nos programas de manejo de T. castaneum em unidades armazenadoras.


ABSTRACT The current work aimed at to investigate the insecticide potential of essential oils of Croton heliotropiifolius, Croton pulegiodorus, Myracrodruon urundeuva and Ocimum basilicum on adults of Tribolium castaneum in stored maize. For each oil, it were performed fumigation tests, repellency and the effect on the instantaneous rate of increase (ri), in five concentrations (0; 5; 10; 15 e 20 μL). Bioassays were carried out under constant temperature conditions (28±2 °C), relative humidity (70±5%) and scot phase of 24 hours. In fumigation different concentrations of test oils were applied on filter paper strips attached on the bottom of the fumigation chamber cover (1.5 L), which contained 20 grams of food substrate and 10 unsexed adults of T. castaneum. The insect mortality was recorded after 48 hours of exposure. The repellency tests were performed in arenas composed of two pots connected to a central box. In a pot it was deposited feed substrate, with concentrations of the essential oil, in the other pot (control) it was deposited only food. Ten adult insects were released in the central box, being exposed for 5 days to evaluate the preference. In the fumigation tests, insecticide activity of the essential oil of M. urundeuva was observed on adults of T. castaneum. In the repellency tests, all the tested oils presented repellent effect. The emergency of T. castaneumreduced between 33% and 100% when they were in the powdered maize treated with the essential oils. Maize grains treated with C. pulegiodorus and O. basilicum essential oils caused a significant decrease in the populations of T. castaneum. The tested oils proved to be an efficient control alternative for the use in managing programs of T. castaneum in storing units.

RESUMO

Silibinin is a polyphenolic plant flavonoid with anti-inflammatory properties. The present study investigated the effect of silibinin on oxidative metabolism and cytokine production - tumor necrosis factor-alpha (TNF-α), interleukin (IL)12, granulocyte-macrophage colony-stimulating factor (GM-CSF), IL-6, IL-10, and transforming growth factor beta (TGF-ß1) - by peripheral blood monocytes (PBM) from preeclamptic pregnant women. It is a case-controlled study involving women with preeclampsia (PE, n = 30) compared with normotensive pregnant (NT, n = 30) and with non-pregnant (NP, n = 30) women. Monocytes were obtained and cultured with or without silibinin (5 µM or 50 µM) for 18 h. Superoxide anion (O2-) and hydrogen peroxide (H2O2) release were determined by specific assays, and cytokine levels were determined by immunoenzymatic assays (ELISA). Monocytes from preeclamptic women cultured without stimulus released higher levels of O22, H2O2 and TNF-α, and lower levels of IL-10 and TGF-ß1 than did monocytes from NT and NP women. Treatment in vitro with silibinin significantly inhibited spontaneous O2- and H2O2 release and TNF-α production by monocytes from preeclamptic women. The main effect of silibinin was obtained at 50 µM concentration. Thus, silibinin exerts anti-oxidative and anti-inflammatory effects on monocytes from preeclamptic pregnant women by inhibiting the in vitro endogenous release of reactive oxygen species and TNF-α production.

RESUMO

The occurrence of persistent organic pollutants (POPs) as polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and polybrominated diphenyl ethers (PBDE) in crabs Hepatus pudibundus and Callinectesdanae was assessed from two different places inside of the Santos Bay and Moela Island near one of the most economically important metropolitan areas in Southern Brazil. Among POPs analyzed, ∑PCBs (222-923 ng g(-1)lipid weight) and ∑DDTs (154-410 ng g(-1)lw) exhibited the highest concentrations in the crabs. ∑HCHs ranged from 10.3 to 30.9 ng g(-1)lw and were found in all individuals. Other OCPs found in lower concentration was Mirex (7.6-41.6 ng g(-1)lw) and HCB (5.83-16.9 ng g(-1)lw). ∑PBDEs (24.1 ng g(-1)lw) were only found in one male individual from the species C. danae collected near to the submarine sewage of Santos. Male crabs showed higher POP concentrations than female crabs for those two species.

RESUMO

Air pollution is associated with morbidity and mortality induced by respiratory diseases. However, the mechanisms therein involved are not yet fully clarified. Thus, we tested the hypothesis that a single acute exposure to low doses of fine particulate matter (PM2.5) may induce functional and histological lung changes and unchain inflammatory and oxidative stress processes. PM2.5 was collected from the urban area of São Paulo city during 24 h and underwent analysis for elements and polycyclic aromatic hydrocarbon contents. Forty-six male BALB/c mice received intranasal instillation of 30 µL of saline (CTRL) or PM2.5 at 5 or 15 µg in 30 µL of saline (P5 and P15, respectively). Twenty-four hours later, lung mechanics were determined. Lungs were then prepared for histological and biochemical analysis. P15 group showed significantly increased lung impedance and alveolar collapse, as well as lung tissue inflammation, oxidative stress and damage. P5 presented values between CTRL and P15: higher mechanical impedance and inflammation than CTRL, but lower inflammation and oxidative stress than P15. In conclusion, acute exposure to low doses of fine PM induced lung inflammation, oxidative stress and worsened lung impedance and histology in a dose-dependent pattern in mice.

RESUMO

Objective: To compare the muscle strength of children and adolescents with growing pains, with and without joint hypermobility, to healthy controls by means of quantitative tests. Method: Forty-seven children and adolescents were monitored because of growing pains: 24 with joint hypermobility (GP-JH group) and 23 without joint hypermobility (GP group). These cases, along with 47 healthy controls matched for age and gender, underwent two quantitative tests for muscle strength evaluation: the Childhood Myositis Assessment Scale (CMAS) and the Manual Muscle Strength Test (MMT). Anthropometric data such as height, weight, body mass index, triceps skinfold, mean arm circumference and arm muscle area were compared between the three groups. Results: The three groups did not present any statistical differences in anthropometric measurements. There were significant differences in median CMAS scores, which were lower in the GP (47; range 39-52) and GP-JH (46; range 40-51) groups than the control group (50; range 45-52; p<0.0001). Two of the timed CMAS exercises (head lift and leg lift duration) had significantly lower scores among the patients than among the controls (p<0.0001). The median MMT scores in the GP (79; range 73-80) and GP-JH (78; range 32-80) groups were also significantly lower than the control group (80, range 78-80; p<0.0001). The best correlation between the CMAS and MMT scores was in the GP-JH group (Spearman r=0.65, p=0.0007). Application of CMAS and MMT on two occasions produced good agreement, with intraclass correlation coefficients of 0.87 (95% CI: 0.64-0.96; p<0.0001) and 0.92 (95% CI: 0.76-0.97; p<0.0001), respectively. Conclusion: Patients with growing pains, with and without joint hypermobility, presented mild to moderate muscle weakness, compared with healthy controls.


Objetivo: Avaliar, por meio de teste quantitativo, a força muscular em crianças e adolescentes com dores de crescimento, associada ou não com hipermobilidade articular e comparadas com controles saudáveis. Método: Quarenta e sete casos de crianças e adolescentes acompanhados por dores de crescimento, sendo 24 com hipermobilidade articular (DC-HA), 23 sem hipermobilidade articular (DC) e 47 controles saudáveis pareados por idade e gênero foram submetidos a dois testes quantitativos para a avaliação da força muscular, o Childhood Myositis Assessment Scale (CMAS) e o Manual Muscle Strength Test (MMT). Os dados antropométricos como altura, peso, índice de massa corporal, prega cutânea tricipital, circunferência média do braço e a área muscular do braço foram comparados entre os três grupos. Resultados: Os três grupos não apresentaram diferença estatística entre as medidas antropométricas. Houve diferença significante entre a mediana da pontuação do CMAS, sendo menores no grupo DC (47, mínimo e máximo 39-52) e DC-HA (46, mínimo e máximo 40-51), comparados com controles (50, mínimo e máximo 45-52; p<0,0001). Dois dos exercícios cronometrados do CMAS, a elevação da cabeça e a duração da elevação das pernas, tiveram menor pontuação nos pacientes comparados aos controles (p<0.0001). A pontuação mediana do MMT no grupo DC (79, mínimo e máximo 73-80) e DC-HA (78, mínimo e máximo 32-80) também apresentou diferença significante, sendo menor nos pacientes que nos controles (80, mínimo e máximo 78-80; p<0,0001). A melhor correlação entre a pontuação do CMAS e MMT foi no grupo DC-HA (Spearman r=0,65; p=0,0007). A aplicação do CMAS e MMT em duas ocasiões apresentou boa concordância e coeficiente de correlação intraclasse de 0,87 (IC 95% 0,64-0,96; p<0,0001) e 0,92 (IC 95% 0,76-0,97; p<0,0001), respectivamente...

RESUMO

OBJECTIVE: To describe onset features, classification and treatment of juvenile dermatomyositis (JDM) and juvenile polymyositis (JPM) from a multicentre registry. METHODS: Inclusion criteria were onset age lower than 18 years and a diagnosis of any idiopathic inflammatory myopathy (IIM) by attending physician. Bohan & Peter (1975) criteria categorisation was established by a scoring algorithm to define JDM and JPM based on clinical protocol data. RESULTS: Of the 189 cases included, 178 were classified as JDM, 9 as JPM (19.8: 1) and 2 did not fit the criteria; 6.9% had features of chronic arthritis and connective tissue disease overlap. Diagnosis classification agreement occurred in 66.1%. Median onset age was 7 years, median follow-up duration was 3.6 years. Malignancy was described in 2 (1.1%) cases. Muscle weakness occurred in 95.8%; heliotrope rash 83.5%; Gottron plaques 83.1%; 92% had at least one abnormal muscle enzyme result. Muscle biopsy performed in 74.6% was abnormal in 91.5% and electromyogram performed in 39.2% resulted abnormal in 93.2%. Logistic regression analysis was done in 66 cases with all parameters assessed and only aldolase resulted significant, as independent variable for definite JDM (OR=5.4, 95%CI 1.2-24.4, p=0.03). Regarding treatment, 97.9% received steroids; 72% had in addition at least one: methotrexate (75.7%), hydroxychloroquine (64.7%), cyclosporine A (20.6%), IV immunoglobulin (20.6%), azathioprine (10.3%) or cyclophosphamide (9.6%). In this series 24.3% developed calcinosis and mortality rate was 4.2%. CONCLUSION: Evaluation of predefined criteria set for a valid diagnosis indicated aldolase as the most important parameter associated with definite JDM category. In practice, prednisone-methotrexate combination was the most indicated treatment.

RESUMO

INTRODUÇÃO: Alterações da função pulmonar após cirurgia abdominal levam à redução do volume pulmonar, prejudicando as trocas gasosas. OBJETIVO: Avaliar os efeitos da cinesioterapia respiratória sobre a função pulmonar e a força muscular respiratória em pacientes submetidos à colecistectomia laparoscópica. MATERIAIS E MÉTODOS: Em estudo prospectivo, 20 mulheres e 16 homens (idade: 48,4 ± 9,55 anos), submetidos à colecistectomia laparoscópica, foram divididos aleatoriamente: 17 realizaram exercícios respiratórios (respiração diafragmática, sustentação máxima da inspiração e inspiração fracionada) e 19 participaram como Grupo Controle. Todos realizaram avaliação das pressões respiratórias máximas (PImax e PEmax), pico de fluxo expiratório (PFE) e espirometria, medindo capacidade vital (CV), capacidade vital forçada (CVF), volume expiratório no primeiro segundo (VEF1), relação VEF1/CVF no pré-operatório e diariamente até o sexto pós-operatório (PO). RESULTADOS: Os valores de pré-operatório não foram estatisticamente diferentes entre os dois grupos. Ambos os grupos apresentaram diminuição de todas as variáveis no 1º PO (p< 0,05). O Grupo Exercício permaneceu com diminuição até o 2º PO para CV, CVF e VEF1 (p< 0,05), 3º PO para PImax e PFE (p< 0,05) e 4º PO para PEmax (p< 0,05), enquanto que, no Grupo Controle, os valores de todas as variáveis retornaram a partir do 5º PO. Os valores de PImax e PEmax foram maiores no Grupo Exercício que no Grupo Controle desde o 3º e 2º PO (p< 0,05), respectivamente. CONCLUSÕES: A cinesioterapia respiratória contribuiu para a recuperação precoce da função pulmonar e da força muscular dos pacientes submetidos à colecistectomia laparoscópica.


INTRODUCTION: Pulmonary function changes following abdominal surgery lead to reduced pulmonary volume, thus compromising gas exchanges. OBJECTIVE: To evaluate the effects of respiratory kinesiotherapy on pulmonary function and respiratory muscle strength in patients who underwent laparoscopic cholecystectomy. METHODS: Twenty women and 16 men (age 48.4 ± 9.55 years) who underwent laparoscopic cholecystectomy were prospectively studied. They were randomly divided as follows: 17 subjects performed breathing exercises (diaphragmatic respiration, maximum sustained inspiration and fractional inspiration) and 19 participated as a Control Group. All of them underwent evaluations of maximal inspiratory and expiratory pressures (MIP and MEP), peak expiratory flow (PEF) and spirometry, with measurements of vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and the FEV1/FVC ratio before the operation and daily until the sixth postoperative day (POD). RESULTS: The preoperative parameters were not statistically different between the two groups. Both groups presented decreases in all variables on the first POD (p< 0.05). The Exercise Group continued to present decreased values until the second POD for VC, FVC, and FEV1 (p< 0.05), until the third POD for MIP and PEF (p< 0.05) and the fourth POD for MEP (p< 0.05). For the Control Group, the values of all the variables began to normalize on the fifth POD. The MIP and MEP values in the Exercise Group were higher than those in the controls, from the third and second POD onwards, respectively. CONCLUSIONS: Respiratory kinesiotherapy contributed towards early recovery of pulmonary function and muscle strength among patients who had undergone laparoscopic cholecystectomy.

RESUMO

We evaluated the prevalence and clinical associations of amenorrhea in 298 female juvenile systemic lupus erythematosus (JSLE) patients (ACR criteria) followed in 12 Brazilian Paediatric Rheumatology centres. Amenorrhea was observed in 35 patients (11.7%) with a mean duration of 7.2 +/- 3.6 months. The hormones were performed in 32/35 patients and none of them had FSH and LH levels above and estradiol below the normal range according to pubertal changes. JSLE patients with amenorrhea were younger (15.04 +/- 2.5 versus 17.8 +/- 3.1 years; P = 0.001), and had a shorter period of time between menarche and current age (3.4 +/- 2.9 versus 6.7 +/- 5.4 years; P = 0.001). Interestingly, the frequency, cumulative dose, number of pulses and duration of intravenous cyclophosphamide treatment were alike in patients with and without amenorrhea (P > 0.05). In contrast, patients with amenorrhea had significantly higher SLEDAI (P = 0.01) and SLICC/ACR-DI (P = 0.024) scores compared to those without this condition. Independent risk factors identified by multivariate analysis were higher SLEDAI (OR = 1.059; CI = 1.004-1.116; P = 0.034) and SLICC/ACR-DI (OR = 2.125; IC = 1.373-3.291; P = 0.001) scores. Our data suggest that in spite of immunosuppressive therapy, JSLE patients have an adequate ovarian follicular reserve and amenorrhea is particularly associated with disease activity and damage.

RESUMO

We report a case of CD8(+)/V beta 5.1(+) T-cell large granular lymphocyte leukemia (T-LGL leukemia) presenting with mild lymphocytosis, severe autoimmune neutropenia, thrombocytopenia, polyarthritis and recurrent infections with a chronic disease course. Immunophenotyping showed an expansion of CD3(+)/TCR alpha beta(+)/CD8(+bright)/CD11c(+)/CD57(-)/CD56(-) large granular lymphocytes with expression of the TCR-V beta 5.1 family. Southern blot analysis revealed a clonal rearrangement of the TCR beta-chain gene. Hematopoietic growth factors, high dose intravenous immunoglobulin and corticosteroids were of limited therapeutic benefit to correct the cytopenias. During the disease course, the patient developed a severe cutaneous leg ulcer and bilateral vascular mammary skin lesions. Treatment with 2-deoxycoformycin resulted in both clinical and hematological complete responses, including the resolution of vascular skin lesions. Combined immuno-staining with relevant T-cell associated and anti-TCR-V beta monoclonal antibodies proved to be a sensitive method to assess the therapeutic effect of 2-deoxycoformicin and to evaluate the residual disease.
