Subacute thyroiditis and rapidly developing goiter in a 16-year-old female: a case report / Tiroiditis Sub-aguda asociada a bocio nodular en una paciente de 16 años; reporte de un caso

Subacute thyroiditis (SAT) is an inflammatory disease of the thyroid gland with multiple etiologies and clinical features, often challenging to recognize. The classic presentation is the painful, granulomatous thyroiditis (DeQuervain's) characterized by diffuse swelling of the gland, usually preceded by an upper respiratory tract infection. A painless variant, also referred to as autoimmune subacute thyroiditis, has been documented and is strongly linked to postpartum state, reported following ~10% of pregnancies. It can be differentiated from the former by the presence of anti-thyroid antibodies, which classifies it as an autoimmune thyroiditis. Any spontaneous development of painful swelling of the thyroid gland warrants a complete work up that includes thyroid hormones, thyroid autoimmune panel, acute phase reactant titers, and, if available, imaging that may lead to the diagnosis of an inflammatory or infectious cause of thyroiditis.

Tiroiditis Subaguda, es una enfermedad inflamatoria de la glándula Tiroides que tiene muchas etiologías y características clínicas, y frecuentemente difícil de reconocer. La presentación clásica es: tiroiditis granu-lomatosa dolorosa caracterizada de hinchazón difusa de la glándula del Tiroides, usualmente precedida de una infección respiratoria de las vías áreas superior (como una infección viral). Existe una variante sin dolor, tam-bién referida como tiroiditis subaguda autoinmune, ha sido documentado y es muy ligada al estado postparto, en un 10% de los embarazos. La Tiroiditis postparto Puede ser diferenciada de la anterior por la presencia de anticuerpos lo que la clasifica como una tiroiditis auto-inmune. Cualquier desarrollo espontaneo de una hin-chazón dolorosa de la tiroides garantiza su evaluación de una manera formal, que incluye las hormonas del tiroides, panel tiroideo de autoinmunidad títulos de los factores que reaccionan agudamente, y si está disponible imágenes como una ultrasonografía que conlleva al di-agnóstico de una Tiroiditis inflamatoria o de origen in-feccioso.

Vasculopatía Livedoide, la punta del témpano: a propósito de un caso / Livedoid vasculopathy, the tip of the iceberg: a case report

Resumen La vasculopatía livedoide (VL), es una enfermedad vascular oclusiva que afecta la microvasculatura, se caracteriza por ser recurrente y no inflamatoria. Su incidencia es de 1/100.000 casos por habitantes, afectando en su mayoría a mujeres de edad media. Su patogenia se desconoce, pero se destaca el componente trombótico de la misma, causado por un estado de hipercoagulabilidad, que conduce a la oclusión vascular, debiendo distinguirse una forma primaria y una secundaria.Clínicamente se observan úlceras dolorosas a nivel maleolar que evolucionan progresivamente a una cicatrización atrófica, blanquecina nacarada y estrellada característica.Presentamos un caso clínico en un varón con múltiples comorbilidades y difícil tratamiento, el cual requirió un trabajo multidisciplinario.

Abstract Livedoid vascular disease (VL), is an occlusive vascular disease that affects the microvasculature, is characterized by being recurrent and non-inflammatory. Its incidence is 1 / 100,000 cases per inhabitant, affecting mostly middle-aged women. Its pathogenesis is unknown, but its thrombotic component stands out, caused by a state of hypercoagulability, which leads to vascular occlusion, and a primary and secondary form must be distinguished. Clinically, painful ulcers are observed at the malleolar level, progressing progressively to characteristic atrophic, pearly whitish and starry healing. We present a clinical case in a male with multiple comorbidities and difficult management, which required multidisciplinary work.

Body composition of women with and without dynapenia defined by different cut-off points / Composição corporal de mulheres com e sem dinapenia definida por diferentes pontos de corte

ABSTRACT Objective To compare body composition of postmenopausal women with and without dynapenia, defined by different cut-off points. Methods Body composition was assessed by electrical bioimpedance and the nutritional status by the body mass index. Dynapenia was diagnosed according to handgrip strength, using the following cut-off points: handgrip strength <16kgf and <20 kgf. Results A total of 171 women (50 to 92 years of age) participated in the investigation. The mean age of non-dynapenic and dynapenic women (handgrip strength <20kgf) was 69.4±8.2 and 74.5±8.2 years, respectively. The mean age of women with dynapenia (handgrip strength <16kgf) was 75.0±10.1 years and non-dynapenic women, 71.1±8.2 years. It was found that dynapenic women, with handgrip strength <20 and <16kgf, had an average of 2.38 and 2.47kg less muscle mass respectively, when compared to non-dynapenic women (p<0.05). However, there was no difference in muscle mass between the different dynapenic groups. Non-dynapenic women (handgrip strength ≥20kgf) had more total (3.55kg) and central fat (1.47kg) (p<0.05). Conclusion Dynapenic women, diagnosed considering both cutoff points, had less total and segmental muscle mass compared to non-dynapenic women. In addition, dynapenic women with handgrip strength <20kgf had lower total and trunk adiposity.

RESUMO Objetivo Comparar a composição corporal de mulheres na pós-menopausa com e sem dinapenia a partir de diferentes pontos de corte. Métodos A composição corporal foi avaliada por bioimpedância elétrica e o estado nutricional pelo índice de massa corporal. A dinapenia foi diagnosticada por meio da força de preensão manual, utilizando-se os seguintes pontos de corte: força de preensão manual <16kgf e <20kgf. Resultados Participaram da pesquisa 171 mulheres (50 a 92 anos). A média de idade das não dinapênicas e das dinapênicas (força de preensão manual <20 kgf) foi 69,4±8,2 e 74,5±8,2 anos, respectivamente. As mulheres com dinapenia pela força de preensão manual <16kgf apresentaram média de idade de 75,0±10,1 anos e as não dinapênicas tinham, em média, 71,1±8,2 anos. Verificou-se que as mulheres dinapênicas, com força de preensão manual <20 e <16kgf, tinham em média 2,38 e 2,47kg a menos de massa muscular quando comparadas às não dinapênicas (p<0,05). Contudo, não foi observada diferença na massa muscular entre os diferentes grupos dinapênicos. As mulheres não dinapênicas (força de preensão manual ≥20kgf) apresentaram maior gordura total (3,55kg) e central (1,47kg) (p<0,05). Conclusão As mulheres dinapênicas, diagnosticadas por ambos os pontos de corte, apresentaram menor massa muscular total e por segmento em relação às não dinapênicas. Ademais, as dinapênicas com força de preensão manual <20kgf possuíam menor adiposidade total e no tronco.

Colonic intussusception as a rare manifestation of colonic lipoma: case report

ABSTRACT Introduction: Colonic lipomas are low-risk lesions that require endoscopic or surgical management depending on their size and symptoms. However, diagnosing a lipomatous lesion in the colon is a difficult task, as the clinical or imaging findings point to a low prevalence of these lesions and a higher frequency in the female sex. The laparoscopic approach is the current method of choice as it represents fewer traumas and, therefore, a faster clinical recovery. Case presentation: 43-year-old female patient, Caucasian, from the city of Bogotá, housewife, without any medical history. She presented with acute abdominal pain associated with tarry stools. Diagnostic imaging tests were performed, finding colo-colonic intussusception, originated in a lipomatous lesion located in the transverse colon. This patient underwent an enlarged laparoscopic right hemicolectomy. Discussion: This case describes how colonic intussusception constitutes a preoperative complication that requires surgical management since its diagnosis considering the associated mortality rates. Conclusion: The analysis of this case is part of the scientific evidence indispensable to improve the diagnostic and therapeutic approach to colonic intussusception, as local and international literature have not addressed this condition sufficiently.

RESUMEN Introducción. Los lipomas en el colon son lesiones con pocos riesgos de malignización que, según su tamaño y sintomatologia, pueden requerir manejo endoscópico o quirúrgico. Sin embargo, es difícil establecer el diagnóstico de una lesión lipomatosa en el colon: los hallazgos clínicos o imagenológicos solo describen que la prevalencia de estas lesiones es baja y que es una patología común en el género femenino. Debido a que el abordaje laparoscópico causa menores traumas y por tanto la recuperación clínica es más rápida, en la actualidad suele elegirse esta opción. Presentación de caso. Paciente femenino de 43 años, raza blanca, procedente de Bogotá D.C., ama de casa y sin antecedentes médicos. La sintomatología que presentó fue dolor abdominal de instauración aguda asociado a deposiciones melénicas, por lo que fue llevada a toma de imágenes diagnósticas donde se documentó intususcepción colocolónica originada en una lesión lipomatosa y localizada en el colon transverso. Se le practicó hemicolectomía derecha ampliada por vía laparoscópica. Discusión. A partir de este caso se describe cómo la intususcepción colónica constituye una complicación preoperatoria que demanda la realización de un manejo quirúrgico desde el mismo diagnóstico dado el margen de los porcentajes de mortalidad. Conclusión. El análisis del presente caso constituye parte de la evidencia científica indispensable para mejorar el abordaje diagnóstico y terapéutico de la intususcepción colónica que la literatura nacional e internacional no ha tratado suficientemente.

Influencia del estrés crónico y de la masticación sobre el dolor / Influence of chronic stress and chewing over the pain

Resumen Introducción: El estrés crónico y la masticación afectan a la respuesta dolora; sin embargo, hay escasos conocimientos sobre la relación entre dichas variables. Objetivo: Determinar la influencia del estrés crónico y la masticación sobre la respuesta al dolor. Métodos: 32 ratones albinos machos de 8 semanas de edad de la cepa Balb/c se dividieron en 4 grupos iguales: Grupo N: masticación normal sin estrés; Grupo NE: Masticación normal + estrés, Grupo D: masticación deficiente sin estrés y Grupo DE: Masticación deficiente + estrés. Se evaluó la respuesta al estímulo doloroso mediante el test de retirada de la cola ante un estímulo térmico. Resultados: Mediante Anova se compararon los 4 grupos experimentales a la décima segunda y décima sexta semana de vida de los ratones, obteniéndose un valor de p = 0,982 y p = 0,176; respectivamente. Mediante t de student para muestras relacionadas se comparó la variación de la respuesta al dolor; se obtuvo un valor de p = 0,52; p = 0,17; p = 0,84 y p = 0,069 para el grupo N, NE, D y DE respectivamente. Conclusión: El estrés crónico y la masticación no modifican la respuesta al dolor en ratones de la cepa Balb/c.

Abstract Introduction: Chronic stress and mastication affect the response to pain; however, there is little knowledge about the relationship between these variables. Objective: Determine the influence of chronic stress and mastication on the response to pain. Methods: thirty-two 8-week-old male Balb/c mice were used. The sample was divided into 4 equal groups: Group N: normal mastication without stress; Group NE: Normal chewing + stress, Group D: deficient chewing without stress and Group DE: Poor chewing + stress. The response to the painful stimulus was evaluated through the tail withdrawal assay due to a thermal stimulus. Results: By comparing the 4 experimental groups to the fourth and the eighth week through the ANOVA test yielded a value of p = 0.982 and p = 0.176; respectively. By applying the 't' student, within each group, in comparison of the variation of the pain response between the fourth and eighth week, the values ​​of p = 0.52; p = 0.17; p = 0.84 and p = 0.069 were obtained for the group N, NE, D and DE respectively. Conclusion: Chronic stress and mastication do not modify the response to pain in albino Balb/c mice.

Influence of acupuncture on the pain perception threshold of muscles submitted to repetitive strain / Influência da acupuntura no limiar de percepção dolorosa de musculatura submetida a esforço repetitivo

ABSTRACT BACKGROUND AND OBJECTIVES: Muscle pain is one of the causes of the leave of absence in physical activities, as well as limiting factor in sports performance. The objective of this study was to evaluate the early and late response to the pain perception threshold after acupuncture in a single application, in subjects submitted to repetitive strain. METHODS: Clinical-experimental quantitative trial, with control group and blind, with 47 healthy women, aged between 18 and 55 years (36.3±10.6), divided deterministically by sequential alternation to the groups: acupuncture (GACP n=16), Sham (Gsham n=16) and control (CGRT n=15). The repetitive strain was performed in the Reformer equipment of the Pilates method, before and after the intervention, with 0,25x40mm needles. The GACP received the needling at point ST36 (Zusanli). The Gsham received superficial needling out of the acupuncture point, and the CGRT only performed the exercise. All patients had the needles for 20 minutes, except for the CGRT who remained only at rest. A digital pressure algometer was used at point BL57 (Chengshan). The algometry was conducted before the intervention and the exercise, immediately after, and after 24 hours. RESULTS: The GACP showed a significant increase in the pain perception threshold when compared to Gsham (p =0.021) and to CGRT (p<0.001) and after 24 hours, with CGRT (p=0.006). The results were coherent with the acupuncture theoretical foundations, suggesting the release of opioid analgesics and applicability in the recovery of post-exercise sore muscles. CONCLUSION: A single acupuncture intervention was able to increase the Pain Perception Threshold immediately and after 24 hours.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor muscular é uma das causas de afastamento de práticas de atividades físicas e fator limitante no desempenho desportivo. O objetivo deste estudo foi avaliar a resposta imediata e tardia do limiar de percepção dolorosa após estímulo de acupuntura em uma única aplicação, em sujeitos submetidos a esforço repetitivo. MÉTODOS: Ensaio clínico-experimental, quantitativo, com grupo controle e encoberto, 47 mulheres sadias, com idades entre 18 e 55 anos (36,3±10,6), separadas por alocação determinista por alternância sequencial em grupos: acupuntura (GACP n=16), Sham (Gsham n=16) e controle (GCRT n=15). Realizou-se o esforço repetitivo no equipamento Reformer do método Pilates, antes e após a intervenção com agulhas 0,25x40mm. O GACP recebeu agulhamento no ponto E36 (Zusanli). O Gsham agulhamento superficial, fora do ponto de estímulo de acupuntura e o GCRT só realizou o exercício. Todos permaneceram 20 min com agulhas e o GCRT só em repouso. Utilizou-se um algômetro de pressão digital no ponto B57 (Chengshan). A algometria foi realizada antes da intervenção e do exercício, imediatamente após, e após 24 horas. RESULTADOS: O GACP teve aumento significativo do limiar de percepção dolorosa no momento imediato, quando comparado ao Gsham (p=0,021) e ao GCRT (p<0,001), e após 24 horas com o GCRT (p=0,006). Houve coerência dos resultados com as bases teóricas do estímulo da acupuntura, sugerindo liberação de opioides analgésicos e aplicabilidade em recuperação de dores musculares pós-exercícios. CONCLUSÃO: Uma única intervenção de acupuntura foi capaz de aumentar o limiar de percepção dolorosa de imediato e após 24 horas.

Systematic review of oral therapy for the treatment of symptoms of bladder pain syndrome: The brazilian guidelines / Revisão sistemática sobre terapia oral para tratamento dos sintomas da síndrome da bexiga dolorosa: as diretrizes brasileiras

Abstract Interstitial cystitis (IC), including bladder pain syndrome (BPS), is a chronic and debilitating disease thatmainly affectswomen. It is characterized by pelvic pain associated with urinary urgency, frequency, nocturia and negative urine culture,with normal cytology. In 2009, the Society for Urodynamics and Female Urology (SUFU) defined the term IC/BPS as an unpleasant sensation (pain, pressure, and discomfort) perceived to be related to the urinary bladder, associated with lower urinary tract symptoms for more than 6 weeks duration, in the absence of infection or other identifiable causes. This is the definition used by the American Urological Association (AUA) in the most recent guidelines on IC/BPS. Interstitial cystitis may be sufficiently severe to have a devastating effect on the quality of life, but it may also be associated with moderate symptoms whose effects are less debilitating. Although there are several clinical trials to assess oral and intravesical therapies, the treatment for IC remains far from ideal. This systematic assessment evaluates published randomized clinical trials on oralmedications used totreat symptoms of BPS. This studywas performed according to the preferred reporting items for systematic reviews and metaanalyses (PRISMA)method. Two independent reviewers screened the studies to determine their inclusion or exclusion and to perform the methodological analysis. The inclusion criteria included randomized studiespublishedbetween April of 1988and April of2016 that used oral medications to treat symptoms of BPS or IC. According to the systematic review performed,we should consider pentosan polysulfate as one of the bestoptions of oral drugs for the treatment of BPS symptoms. However, this drug is not an available option in Brazil. Orally administered amitriptyline is an efficacious medical treatment for BPS, and it should be the first treatment offered.

Resumo Cistite intersticial (IC), incluindo a síndrome da bexiga dolorosa (SBD), é uma doença crônica e debilitante que afeta principalmente mulheres. É caracterizada por dor pélvica associada à urgência miccional, frequência urinária, noctúria e exame cultural de urina negativo, com citologia normal. A cistite intersticial pode ser suficientemente severa para ter um efeito devastador na qualidade de vida, mas também pode estar associada a sintomas moderados e menos debilitantes. Embora existam vários ensaios clínicos para avaliar terapias orais e intravesicais, o tratamento para IC permanece longe do ideal. Esta revisão sistemática avaliou ensaios clínicos randomizados publicados sobre medicamentos orais usados para tratar sintomas de SBD. Este estudo foi realizado de acordo com ométodo preferred reporting items for systematic reviews and meta-analyses (PRISMA). Dois revisores independentes examinaram os estudos para determinar sua inclusão ou exclusão e para realizar a análise metodológica. Os critérios de inclusão foram: ensaios clínicos randomizados publicados entre abril de 1988 e abril de 2016 que usaram medicações orais no tratamento dos sintomas da SBD ou CI. De acordo com a revisão sistemática realizada, a melhor opção de medicação oral para o tratamento dos SBD é o pentosano polissulfato sódico. No entanto, esta droga não está disponível no Brasil. A amitriptilina administrada por via oral é um tratamento eficaz para SBD e deve ser oferecida como primeira escolha.

The effectiveness of Kinesio Taping on pain and disability in cervical myofascial pain syndrome / Efetividade do kinesio taping na dor e incapacidade na síndrome dolorosa miofascial cervical

Abstract Objective: The aim of this study was to investigate the effectiveness of Kinesio Taping and sham Kinesio Taping on pain, pressure pain threshold, cervical range of motion, and disability in cervical myofascial pain syndrome patients (MPS). Methods: This study was designed as a randomized, double-blind placebo controlled study. Sixty-one patients with MPS were randomly assigned into two groups. Group 1 (n = 31) was treated with Kinesio Taping and group 2 (n = 30) was treated sham taping five times by intervals of 3 days for 15 days. Additionally, all patients were given neck exercise program. Patients were evaluated according to pain, pressure pain threshold, cervical range of motion and disability. Pain was assessed by using Visual Analog Scale, pressure pain threshold was measured by using an algometer, and active cervical range of motion was measured by using goniometry. Disability was assessed with the neck pain disability index disability. Measurements were taken before and after the treatment. Results: At the end of the therapy, there were statistically significant improvements on pain, pressure pain threshold, cervical range of motion, and disability (p < 0.05) in both groups. Also there was a statistical difference between the groups regarding pain, pressure pain threshold, cervical flexion-extension (p < 0.05); except cervical rotation, cervical lateral flexion and disability (p > 0.05). Conclusion: This study shows that Kinesio Taping leads to improvements on pain, pressure pain threshold and cervical range of motion, but not disability in short time. Therefore, Kinesio Taping can be used as an alternative therapy method in the treatment of patients with MPS.

Resumo Objetivo Investigar a eficácia do kinesio taping e do taping placebo sobre a dor, limiar de dor à pressão, amplitude de movimento cervical e incapacidade em pacientes com síndrome dolorosa miofascial (SDM) cervical. Métodos: Ensaio clínico randomizado duplo-cego controlado por placebo. Foram alocados em dois grupos, aleatoriamente, 61 pacientes com SDM. O grupo 1 (n = 31) foi tratado com kinesio taping e o grupo 2 (n = 30) foi tratado com taping placebo cinco vezes em intervalos de três dias, durante 15 dias. Além disso, todos os pacientes foram submetidos a um programa de exercícios para o pescoço. Os pacientes foram avaliados em relação à dor, ao limiar de dor à pressão, à amplitude de movimento cervical e à incapacidade. A dor foi avaliada com a escala visual analógica, o limiar de dor à pressão foi medido com um algômetro e a amplitude de movimento cervical ativa foi mensurada com a goniometria. A incapacidade foi avaliada com o Neck Pain Disability Scale. As mensurações foram feitas antes e depois do tratamento. Resultados: No fim do tratamento, houve melhoria estatisticamente significativa na dor, no limiar de dor à pressão, na amplitude de movimento cervical e na incapacidade (p < 0,05) em ambos os grupos. Também houve uma diferença estatisticamente significativa entre os grupos em relação à dor, ao limiar de dor à pressão e à flexão-extensão cervical (p < 0,05); não houve diferença na rotação cervical, flexão lateral cervical e incapacidade (p > 0,05). Conclusão: O kinesio taping leva à melhoria na dor, no limiar de dor à pressão e na amplitude de movimento cervical, mas não na incapacidade em um curto período. Portanto, o kinesio taping pode ser usado como um método de terapia opcional para o tratamento de pacientes com SDM.

Se hace referencia al cuadro clínico de estos enfermos con especial énfasis en las maniobras más empleadas. En relación al tratamiento quirúrgico se describen las dos variedades de tratamiento por la vía artroscópica, así como las complicaciones más frecuentes. Conclusiones: la descompresión subacromial por la vía artroscópica es efectiva en pacientes con compresión subacromial, es un método factible con un mínimo de complicaciones.

Background: subacromial compression is the most common cause of shoulder pain. Its treatment varies from conservative to surgical. However, surgical treatment by arthroscopy is better in regards to functional and cosmetic points of view. Objective: to deepen into the importance of subacromial decompression by arthroscopy in patients with subacromial compression. Methods: a search in the databases Pubmed, Hinari, SciELO and Medline was carried out through the management information software EndNote by using the words subacromial compression and arthroscopic subacromial decompression, resulting in a total of 570 articles, in which 56 of them were selected for review, 53 of them in the last five years, including three books. Development: important aspects related to subacromial compression causes were described and divided in intrinsic, extrinsic, and secondary. Specific maneuvers and clinical presentation were pointed. In regards to surgical treatment, a couple of arthroscopic surgical modalities were described as well as complications. Conclusions: arthroscopic subacromial decompression is an effective surgical modality in patients suffering from subacromial compression; it’s a safe procedure with few complications.

Estudio seriado de anticuerpos naturales antibanda 3 en enfermos con drepanocitosis / Natural band 3 antibodies follow up study in sickle cell anemia patients

Introducción: Se ha demostrado la participación de moléculas de adhesión, tanto en eritrocitos con hemoglobina SS, como en el endotelio vascular; así como factores plasmáticos en el fenómeno de vasoclusión en la drepanocitosis. La banda 3 se refiere a una familia de intercambiadores aniónicos presentes en la membrana de todas las células y organelos celulares, las que bajo ciertas condiciones se agregan en la superficie del eritrocito y son reconocidos por anticuerpos naturales como parte del mecanismo de eliminación de eritrocitos senescentes u oxidados. Objetivo: Evaluar la posible participación de los anticuerpos naturales antibanda 3 en el fenómeno oclusivo en la drepanocitosis. Métodos: Se realizó la determinación seriada de anticuerpos naturales antibanda 3 en 19 enfermos con drepanocitosis en diferentes estadios clínicos mediante un ensayo inmunoenzimático en microplacas acopladas con la proteína banda 3. Resultados: Se demostró una disminución significativa (p < 0.01) de anticuerpos naturales antibanda 3 en las muestras de los enfermos obtenidas en las fases de crisis vasoclusiva dolorosa, disminución que pudiera estar relacionada con un consumo elevado de estos en el proceso de eliminación de eritrocitos SS oxidados de la circulación sanguínea. Las muestras en estado basal se mantuvieron dentro de los límites normales. Conclusión: Los resultados sugieren la participación de los anticuerpos naturales antibanda 3 como elemento regulador de la no adhesión de los eritrocitos SS al endotelio vascular en esta enfermedad(AU)

Introduction : The involvement of adhesion molecules in erythrocytes with hemoglobin SS, in vascular endothelium and also plasma factors have been shown in the vasoocclusion phenomenon in sickle cell anemia (SCA). Band 3 refers to a family of anion exchangers present in the membrane of all cells and cellular organelles which under certain conditions cluster on the erythrocyte surface being recognized by natural antibodies as part of the mechanism of removal of senescent or oxidized erythrocytes. Objective : To evaluate the possible participation of natural anti band 3 antibodies in the occlusive phenomenon in SCA. Methods : A follow up study to determine the presence of natural band 3 antibodies in 19 patients with SCA in different clinical stages was performed using an enzyme immunoassay in microplates coupled with the band 3 protein. Results : Significant low levels (p<0.01) of natural band 3 antibodies were demonstrated in the samples of patients obtained in painful vasoocclusive crisis stages, decrease which may be related to a high consumption of antibodies in the process of removing oxidized SS erythrocytes from blood circulation. Steady state samples were within normal range. Conclusion: The results suggest the involvement of natural band 3 antibodies in the regulation of the adherence of SS erythrocytes to vascular endothelium in SCA(AU)

Activation of C-fiber nociceptors by low-power diode laser / Ativação por laser de diodo de baixa potência de nociceptores relacionados a fibras C

ABSTRACT Objective The evaluation of selective activation of C-fibers to record evoked potentials using the association of low-power diode laser (810 nm), tiny-area stimulation and skin-blackening. Method Laser-evoked potentials (LEPs) were obtained from 20 healthy young subjects. An aluminum plate with one thin hole was attached to the laser probe to provide tiny-area stimulation of the hand dorsum and the stimulated area was covered with black ink. Results The mean intensity used for eliciting the ultra-late laser-evoked potential (ULEP) was 70 ± 32 mW. All subjects showed a clear biphasic potential that comprised a negative peak (806 ± 61 ms) and a positive deflection (1033 ± 60 ms), corresponding to the ULEP related to C-fiber activation. Conclusion C-fiber-evoked responses can be obtained using a very low-power diode laser when stimulation is applied to tiny areas of darkened skin. This strategy offers a non-invasive and easy methodology that minimizes damage to the tissue.

Todos os sujeitos apresentaram respostas claras compreendendo dois picos um negativo (806 ± 61 ms) seguido por outro positivo (1033 ± 60 ms), correspondendo ao potencial evocado tardio por estimulação de fibras C. Conclusão Respostas de fibras C podem ser obtidas utilizando-se laser de baixa potência quando a estimulação é aplicada a pequenas áreas de pele escurecida. Esta estratégia oferece uma metodologia não invasiva que minimiza danos teciduais.

Apoplejía tumoral pituitaria / Pituitary tumor apoplexy

La apoplejía tumoral pituitaria es un síndrome infrecuente que resulta del infarto y/o hemorragia espontánea de un adenoma pituitario preexistente. Ya que el evento primario involucra el adenoma, este síndrome debe ser nombrado como apoplejía tumoral pituitaria y no como apoplejía pituitaria. El aumento súbito en la presión de los contenidos de la silla turca da como resultado una cefalea de inicio agudo (puede ser incluso una "cefalea en trueno") de intensidad severa, alteraciones visuales y compromiso en la función pituitaria. El diagnóstico se basa en una alta sospecha clínica, imagen por resonancia magnética y medición de hormonas hipofisiarias en sangre. El tratamiento se basa en medidas de soporte (líquidos intravenosos y corticoides) y en casos sin buena respuesta o con deterioro neurológico, descompresión de silla turca. A continuación presentamos el caso de un adenoma previamente no diagnosticado que debutó como apolejía tumoral pituitaria. (Acta Med Colomb 2015; 40: 249-253).

Pituitary tumor apoplexy is an infrequent condition resulting from infarction and/or spontaneous bleeding from a pre-existing pituitary adenoma. This entity requires the prior existence of an adenoma in order to be named as pituitary tumor apoplexy, otherwise, it should be named pituitary apoplexy. The sudden increase in pressure of the sella turcica's contents results in a clinical syndrome characterized by headache (which can be "thunderclap headache"), visual disturbances and hypopituitarism. Diagnosis is not always straight forward and requires high clinical suspicion in addition to magnetic resonance imaging and measurement of serum pituitary hormones. Treatment is mainly based on supportive measures (intravenous fluids and steroids) and surgical decompression in those cases with no response to medical treatment and progressive neurological impairment. We report the case of a patient with a previously unknown pituitary adenoma presenting as a tumor apoplexy. (Acta Med Colomb 2015; 40: 249-253).

Identificación de riesgos biomecánicos de los/as trabajadores en plantas de proceso de salmón para la prevención de disfunción dolorosa de extremidad superior (DDES) / Identification of biomechanical risks / as workers salmon processing plants for the prevention of upper extremity painful dysfunction (DDES)

Investigación realizada en 3 plantas procesadoras de Salmón de la Provincia de Chiloé, Chile. Se obtuvo una muestra de 150 trabajadores sanos, de ambos sexos, los que fueron grabados en 2 planos y 2 ciclos de trabajo. Los datos que se obtuvieron fueron analizados a través de CheckList-OCRA y procesados estadísticamente mediante el Software IBM SPSS Statistics. Los resultados indican que en las tareas realizadas por los trabajadores los factores de riesgo biomecánicos más críticos y que tienen mayor importancia en el valor del índice intrínseco (CheckList OCRA) son: Postura (valores de correlación 0,89 y 0,87 para la extremidad superior derecha e izquierda, respectivamente); Fuerza (valores de correlación 0,86 y 0,87 para la extremidad superior derecha e izquierda, respectivamente); y, Frecuencia (valores de correlación 0,81 y 0,71 para la extremidad superior derecha e izquierda, respectivamente). Por otra parte, de un total de 21 puestos evaluados, un 67% (14) presentan un nivel de riesgo "alto" (valores de índice intrínseco sobre 22,5). De estos, la mayor cantidad de trabajadores se concentra en los puestos de Despinado Manual y Decorado (70% del total de la muestra). Las conclusiones de la investigación apuntan a que los mayores esfuerzos de prevención se debieran enfocar en los puestos críticos (nivel de riesgo alto-medio), principalmente hacia aquellos que involucran a una mayor masa de trabajadores (Despinado Manual y Decorado). Estas indicaciones debiesen estar dirigidas al mejoramiento de la técnica de trabajo, eliminación de acciones técnicas inútiles, perfeccionamiento de herramientas, rediseño de la línea de producción y layout, además de rotación de funciones.

Research conducted in 3 salmon processing plants in the province of Chiloé, Chile. A sample of 150 healthy workers of both sexes was obtained, which was recorded in 2 planes and 2 cycles. The data obtained were analyzed through CheckList-OCRA and processed statistically using IBM SPSS Statistics Software. The results indicate that the tasks performed by workers factors most critical biomechanical risk and that are most important intrinsic value index (CheckList OCRA) are: Posture (correlation values 0,89 and 0,87 for the tip upper right and left, respectively); Strength (correlation values 0,87 and 0,86 for the upper right and left end, respectively); and frequency (correlation values 0,81 and 0,71 for the right upper extremity and left, respectively). Moreover, a total of 21 seats tested, 67% (14) have a level of "high" (values intrinsic rate of 22,5) risk. Of these, the largest number of workers are concentrated in positions of despinado Manual and Scenery (70% of total sample). The research findings suggest that older Prevention efforts should focus on critical positions (middle-level high risk), mainly to those involving a greater mass of workers (despinado Manual and decorado). These indications are slated to be aimed at improving technical work, elimination of unnecessary technical actions, improved tools, redesigning the production line layout, plus rotation functions.
