Efeitos imediatos da mobilização com movimento na dor, Amplitude de movimento e actividade electromiográfica dos músculos da cintura escapular em indivíduos com síndrome do conflito subacromial

Introdução: A síndrome do conflito subacromial (SCSA) é a causa mais frequente de dor no ombro. Alterações na cinemática escapuloumeral e na activação dos músculos escapulares têm sido identificadas em pessoas com SCSA. A mobilização com movimento (MWM) é uma técnica de terapia manual, desenvolvida por Mulligan, que visa normalizar a cinemática articular. Objectivos: Determinar os efeitos imediatos da MWM na dor, na amplitude de movimento (ADM) de abdução no plano da escápula (APE), e na amplitude do sinal electromiográfico (EMG) do trapézio e grande dentado (GD), em pessoas com SCSA. Métodos: Foram incluídas no estudo 24 pessoas com SCSA, divididas de forma aleatória em 2 grupos de 12, MWM e Placebo. As medidas de resultados avaliadas foram: a dor nos testes de Neer e Hawkins-Kennedy; o limiar de dor à pressão; a ADM de APE até ao início da dor; e a percentagem da contracção isométrica voluntária máxima dos músculos trapézio (superior, médio e inferior) e GD. Resultados: A aplicação da MWM resultou numa significativa diferença, com redução da dor, no teste de Hawkins-Kennedy (p=0,028), num aumento do limiar de dor à pressão (p=0,002) e da ADM de APE até ao início da dor (p=0,010), e numa diminuição da actividade EMG do trapézio superior (TS), na fase concêntrica, abaixo dos 90˚ (p=0,028), comparativamente ao grupo Placebo. Foi, ainda, identificada uma diminuição estatisticamente significativa da actividade EMG do TS, nas restantes fases do movimento (p<0,05), um aumento do limiar de dor à pressão (p<0,001) e da ADM até ao início da dor (p=0,006) entre, antes e após a intervenção com MWM. Conclusão: A MWM poderá ser uma técnica efectiva em indivíduos com SCSA, pelos seus efeitos na redução de dor, aumento de ADM até ao início da dor e diminuição da actividade EMG do TS.

Agenesia do ligamento cruzado anterior – estudo de caso

A agenesia do ligamento cruzado anterior é uma condição extremamente rara. Dada a importância desta estrutura na função muscular, cinética e cinemática do joelho, especula-se que muitas serão as alterações decorrentes desta patologia . Perante o caso de uma atleta com agenesia do ligamento cruzado anterior, este trabalho pretendeu estudar os possíveis défices resultantes desta condição e, perceber se as alterações encontradas no membro com agenesia constituem uma estratégia de compensação eficaz, para um joelho com ausência do ligamento cruzado anterior. Desta forma , foi realizada uma avaliação da força dos músculos quadricípite e isquiotib iais , num dinamómet ro isocinético, a 60°/s e 180°/s. Fo i também recolhido o sinal electromiográfico do vasto medial, bicípite femural e gastrocnémio medial, durante a realização do salto vertical e horizontal. Os dados foram comparados bilateralmente. Os resultados evidenciaram um défice de força dos extensores do joelho com agenesia do LCA. No entanto, para os isqu iotibiais esse défice não foi evidente. A electromiografia não revelou uma estratégia de compensação consistente. Contudo, os resultados realçaram a importância dos flexores do joelho e plantares na estabilização dinâmica de um joelho com ausência do ligamento cruzado anterior. Concluiu-se que as alterações encontradas não formam uma adaptação eficiente .

Mediastinal and pulmonary entomophthoromycosis with superior vena cava syndrome: case report

The first case of mediastinal and pulmonary entomophthoromycosis with supe rior vena cava syndrome is reported. The patient presented with a history of edema of the face, neck and upper limbs as well as collateral circulation in the anterior wall of the chest. Histological examination of tissue from mediastinum revealed a granulomatous reaction with microabscesses surrounded by eosinophilic amorphous material and with broad hyphae in the center. Culture was not performed because a preliminary diagnosis of nonHodgkin's malignant lymphoma was made. Surgical correction of the obstructed area was performed and the patient was sucessfully treated with potassium iodide. The authors propose that mediastinal entomoph thoromycosis must be considered in the differential diagnosis of diseases causing superior vena cava syndrome in tropical and sub-tropical regions. This case enlarges the spectrum of clinical manifestations of the zigomycosis caused by Entomoph-thoraceae.

Força Muscular Isocinética após Reconstrução do Ligamento Cruzado Anterior – Influência do Tipo de Enxerto (Osso-Tendão-Osso/Isquio-Tibiais)

Introdução: É reconhecida a importância do ligamento cruzado anterior (LCA) no funcionamento normal do joelho. Em caso de rotura ligamentar, nomeadamente em desportos com marcada solicitação dos movimentos de rotação do joelho, é justificada a necessidade de reconstrução do LCA na maioria dos casos. Objetivo (s): Avaliar a influência do tipo de enxerto na reconstrução do ligamento cruzado anterior na força muscular isocinética, assim como na funcionalidade e sintomas após 6 meses. Métodos: Estudo transversal analítico, constituído por 20 indivíduos voluntários do sexo masculino, que haviam sido submetidos a uma ligamentoplastia do cruzado anterior, pelo mesmo cirurgião, seguido de uma intervenção individualizada por um fisioterapeuta. Em 10 indivíduos, o procedimento cirúrgico foi realizado com enxerto do tendão rotuliano (grupo OTO), e nos restantes 10 com enxerto do semitendinoso e gracilis (grupo STG). Como forma de avaliar a Força Muscular Isocinética (Peak Torque, Trabalho Total Muscular, ratio Isquiotibiais/Quadricipite), foi utilizado o Dinamómetro Isocinético Biodex. A avaliação foi efectuada apenas aos 6 meses após o procedimento cirúrgico. Para observação da funcionalidade, amplitude de movimento e sintomas, utilizou-se o questionário International Knee Documentation Committee (IKDC). Resultados: Foi possível observar que entre os grupos apenas se observaram diferenças significativas no peak torque de extensão a 180º no membro não lesado (p=0,019). Contudo, foi observada uma tendência para o grupo OTO apresentar um maior défice no peak torque e trabalho total muscular em extensão. Comparativamente ao membro contra-lateral, o membro lesado apresentou valores significativamente inferiores na maioria das variáveis ( p < 0,05). Conclusão: Após 6 meses de pós-cirúrgico com reabilitação de fisioterapia, não foi possível apontar qual o enxerto que garante uma melhor recuperação da força muscular. Aos 6 meses, ambos os grupos ainda apresentaram limitações musculares, quando comparados com o lado contra-lateral. Relativamente ao rácio isquiotibiais/quadricípite, assim como no IKDC, não se observaram diferenças entre os dois tipos de enxertos.

Neurogenic Thoracic Outlet Syndrome Associated with Cervical Rib

A true neurogenic thoracic outlet syndrome (TOS) associated with a cervical rib is considered extremely rare. The authors present their experience with 5 cases of true neurogenic TOS associated with a cervical rib. All patients were female and had a cervical rib confirmed radiographically pre-operatively. Average age was 34,8 years. Although all patients had been treated with several combinations of diverse drugs and a rehabilitation program before referral to surgery, all described their pain as intense and debilitating before surgical treatment. All patients had pre-operative electromyographic abnormalities. Patients were operated on via a supraclavicular approach and the cervical rib was resected. No intra-operative or postoperative complications were noted. Two years postoperatively, all patients mentioned improvement. However, only 2 were symptomless, and on no medication. In one patient there was significant improvement, and in the remaining 2 patients some residual pain persisted that had to be dealt with pharmacologically. All patients were able to resume their daily life activities. Recovery was poorer in the 2 patients that had been referred to surgery after a longer period of time since the beginning of symptoms.

Hyper-IgD and Periodic Fever Syndrome: a New MVK Mutation (p.R277G) Associated with a Severe Phenotype

Hyperimmunoglobulinemia D and periodic fever syndrome (HIDS; MIM#260920) is a rare recessively-inherited autoinflammatory condition caused bymutations in the MVK gene, which encodes for mevalonate kinase, an essential enzyme in the isoprenoid pathway. HIDS is clinically characterized by recurrent episodes of fever and inflammation. Herewe report on the case of a 2 year-old Portuguese boy with recurrent episodes of fever, malaise, massive cervical lymphadenopathy and hepatosplenomegaly since the age of 12 months. Rash, arthralgia, abdominal pain and diarrhea were also seen occasionally. During attacks a vigorous acute-phase response was detected, including elevated erythrocyte sedimentation rate, C-reactive protein, serum amyloid A and leukocytosis. Clinical and laboratory improvement was seen between attacks. Despite normal serum IgD level, HIDS was clinically suspected. Mutational MVK analysis revealed the homozygous genotype with the novel p.Arg277Gly (p.R277G) mutation, while the healthy non consanguineous parents were heterozygous. Short nonsteroidal anti-inflammatory drugs and corticosteroid courses were given during attacks with poor benefits, where as anakinra showed positive responses only at high doses. The p.R277Gmutation here described is a novel missense MVK mutation, and it has been detected in this casewith a severe HIDS phenotype. Further studies are needed to evaluate a co-relation genotype, enzyme activity and phenotype, and to define the best therapeutic strategies.

Hand, Foot, and Mouth Syndrome in an Immunocompetent Adult: a Case Report

BACKGROUND: Hand, foot, and mouth syndrome (HFMS) is a common acute illness. It is characterized by mild clinical symptoms including fever, blisters, and sores in the mouth and on the palms and soles following a 3- to 7-day incubation period. This syndrome is rarely seen in adults. CASE PRESENTATION: A 35-year-old male Caucasian patient had a history of multiple episodes of acute pharyngitis, hypertension, hypercholesterolemia, and occasional abdominal pain. He presented with polyarthralgia in the knees and hands and odynophagia, followed by fever, oral mucosal aphthous lesions, and vesicles on the palms and soles. Three weeks after presentation, he was admitted to the emergency room with acute myocarditis. The in-hospital evaluation revealed positive serology for coxsackie A9 (1:160), positive anti-transglutaminase and anti-gliadin antibodies, normal immunoglobulins, and human immunodeficiency virus negativity. CONCLUSION: We herein describe a case of HFMS that was associated with coxsackie A9 infection complicated by acute myocarditis. Although an association between celiac disease and HFMS has not been described, this patient's immunologic disruption could have favored the development of infection and ultimately HFMS.

Acute Sheehan's Syndrome Presenting as Central Diabetes Insipidus

Sheehan's syndrome occurs as a result of ischaemic pituitary necrosis due to severe postpartum haemorrhage. Improvements in obstetrical care have significantly reduced its incidence in developed countries, but postpartum pituitary infarction remains a common cause of hypopituitarism in developing countries. We report a case of severe postpartum haemorrhage followed by headache, central diabetes insipidus and failure to lactate, which prompted us to investigate and identify both anterior and posterior pituitary deficiency compatible with Sheehan's syndrome. A timely diagnosis allowed us to implement an adequate treatment and follow-up plan, which are known to improve clinical status and patient outcome.

Electromyography function, disability degree, and pain in leprosy patients undergoing neural mobilization treatment

INTRODUCTION: This study aimed to evaluate the effect of the neural mobilization technique on electromyography function, disability degree, and pain in patients with leprosy. METHODS: A sample of 56 individuals with leprosy was randomized into an experimental group, composed of 29 individuals undergoing treatment with neural mobilization, and a control group of 27 individuals who underwent conventional treatment. In both groups, the lesions in the lower limbs were treated. In the treatment with neural mobilization, the procedure used was mobilization of the lumbosacral roots and sciatic nerve biased to the peroneal nerve that innervates the anterior tibial muscle, which was evaluated in the electromyography. RESULTS: Analysis of the electromyography function showed a significant increase (p<0.05) in the experimental group in both the right (Δ%=22.1, p=0.013) and the left anterior tibial muscles (Δ%=27.7, p=0.009), compared with the control group pre- and post-test. Analysis of the strength both in the movement of horizontal extension (Δ%right=11.7, p=0.003/Δ%left=27.4, p=0.002) and in the movement of back flexion (Δ%right=31.1; p=0.000/Δ%left=34.7, p=0.000) showed a significant increase (p<0.05) in both the right and the left segments when comparing the experimental group pre- and post-test. The experimental group showed a significant reduction (p=0.000) in pain perception and disability degree when the pre- and post-test were compared and when compared with the control group in the post-test. CONCLUSIONS: Leprosy patients undergoing the technique of neural mobilization had an improvement in electromyography function and muscle strength, reducing disability degree and pain.

Skin lesions simulating blue toe syndrome caused by prolonged contact with a millipede

Venomous animals are those that, by means of a hunting and defense mechanism, are able to inject their prey with a toxic substance produced in their bodies, directly from specialized glands (e.g., tooth, sting, spur) through which the poison passes. Millipedes are poisonous animals; they can be harmful to humans, and their effects usually manifest as erythematous, purpuric, and cyanotic lesions; local pain; and paresthesia. Here, we report a case of skin contact with a millipede for 6h resulting in skin lesions similar to blue toe syndrome.

Chest pain in the emergency room. Importance of a systematic approach

OBJECTIVE: To evaluate the efficiency of a systematic diagnostic approach in patients with chest pain in the emergency room in relation to the diagnosis of acute coronary syndrome (ACS) and the rate of hospitalization in high-cost units. METHODS: One thousand and three consecutive patients with chest pain were screened according to a pre-established process of diagnostic investigation based on the pre-test probability of ACS determinate by chest pain type and ECG changes. RESULTS: Of the 1003 patients, 224 were immediately discharged home because of no suspicion of ACS (route 5) and 119 were immediately transferred to the coronary care united because of ST elevation or left bundle-branch block (LBBB) (route 1) (74% of these had a final diagnosis of acute myocardial infarction [AMI]). Of the 660 patients that remained in the emergency room under observation, 77 (12%) had AMI without ST segment elevation and 202 (31%) had unstable angina (UA). In route 2 (high probability of ACS) 17% of patients had AMI and 43% had UA, whereas in route 3 (low probability) 2% had AMI and 7 % had UA. The admission ECG has been confirmed as a poor sensitivity test for the diagnosis of AMI ( 49%), with a positive predictive value considered only satisfactory (79%). CONCLUSION: A systematic diagnostic strategy, as used in this study, is essential in managing patients with chest pain in the emergency room in order to obtain high diagnostic accuracy, lower cost, and optimization of the use of coronary care unit beds.

Efficacy of a diagnostic strategy for patients with chest pain and no ST-segment elevation in the emergency room

PURPOSE: To evaluate the efficacy of a systematic model of care for patients with chest pain and no ST segment elevation in the emergency room. METHODS: From 1003 patients submitted to an algorithm diagnostic investigation by probability of acute ischemic syndrome. We analyzed 600 ones with no elevation of ST segment, then enrolled to diagnostic routes of median (route 2) and low probability (route 3) to ischemic syndrome. RESULTS: In route 2 we found 17% acute myocardial infarction and 43% unstable angina, whereas in route 3 the rates were 2% and 7%, respectively. Patients with normal/non--specific ECG had 6% probability of AMI whereas in those with negative first CKMB it was 7%; the association of the 2 data only reduced it to 4%. In patients in route 2 the diagnosis of AMI could only be ruled out with serial CKMB measurement up to 9 hours, while in route 3 it could be done in up to 3 hours. Thus, sensitivity and negative predictive value of admission CKMB for AMI were 52% and 93%, respectively. About one-half of patients with unstable angina did not disclose objective ischemic changes on admission. CONCLUSION: The use of a systematic model of care in patients with chest pain offers the opportunity of hindering inappropriate release of patients with ACI and reduces unnecessary admissions. However some patients even with normal ECG should not be released based on a negative first CKMB. Serial measurement of CKMB up to 9 hours is necessary in patients with medium probability of AMI.

Chest Pain Units: A Modern Way of Managing Patients with Chest Pain in the Emergency Department

It is estimated that 5 to 8 million individuals with chest pain or other symptoms suggestive of myocardial ischemia are seen each year in emergency departments (ED) in the United States 1,2, which corresponds to 5 to 10% of all visits 3,4. Most of these patients are hospitalized for evaluation of possible acute coronary syndrome (ACS). This generates an estimated cost of 3 - 6 thousand dollars per patient 5,6. From this evaluation process, about 1.2 million patients receive the diagnosis of acute myocardial infarction (AMI), and just about the same number have unstable angina. Therefore, about one half to two thirds of these patients with chest pain do not have a cardiac cause for their symptoms 2,3. Thus, the emergency physician is faced with the difficult challenge of identifying those with ACS - a life-threatening disease - to treat them properly, and to discharge the others to suitable outpatient investigation and management.

Ultrasound Blocks for the Anterior Abdominal Wall - Adult and Pediatric Surgery

Somatic post-surgical pain is invalidating and distressing to patients and carries the risk of important complications. The anterior abdominal wall is involved in most surgical procedures in general, gynecologic, obstetric, urological, vascular and pediatric surgery. Combined multimodal strategies involving nerve blocks, opiates, and non-steroidal anti-inflammatory drugs for systemic analgesia are necessary for optimal pain modulation. Anterior abdominal wall blocks, transverse abdominal plexus block, iliohypogastric and ilioinguinal nerveblock, genitofemoral nerve block and rectus sheath block have an important role as components of multimodal analgesia for somatic intraoperative and postoperative pain control. Ultrasound visualization has improved the efficacy and safety of abdominal blocks and implemented the application in the clinical setting. For this reason, they are a very important tool for all anesthesiologists who aim to treat effectively patients’ pain. This guide provides an evidence based comprehensive and necessary overview of anatomical, anesthesiological and technical information needed to safely perform these blocks.
