Neoplasia quística mucinosa hepática, reporte de un caso y análisis de la patología / Hepatic mucinous cystic neoplasm, case report and pathology analysis / Neoplasia cística mucinosa hepática, relatório de um caso e análise da patologia

Desde los primeros reportes en la bibliografía, la nomenclatura de las lesiones quísticas hepatobiliares se ha ido modificando, habiéndose descripto dos tipos de lesiones: las serosas y las mucinosas. En 2010 la Organización Mundial de la Salud estableció una nueva clasificación donde los términos cistoadenomas y cistoadenocarcinomas hepatobiliares son reemplazados por entidades más específicas como la neoplasia mucinosa quística y los tumores quísticos intraductales (neoplasia papilar intraductal, neoplasma tubulopapilar intraductal y neoplasma oncocitico papilar). En cuanto a la neoplasia mucinosa quística, la presencia de estroma ovárico le confiere características distintivas en lo patológico y biológico, siendo esto un requisito en la clasificación de la OMS. Esta característica lo diferencia de los hamartomas biliares, los quistes congénitos y la enfermedad de Caroli. Dichas neoplasias son infrecuentes, con una incidencia menor al 5% de las lesiones quísticas hepáticas y ocurren casi exclusivamente en mujeres, frecuentemente perimenopáusicas. Su potencial de malignización ha sido descrito, siendo éste la indicación de tratamiento quirúrgico resectivo. Presentamos el caso clínico de una paciente portadora de una neoplasia quística mucinosa hepática, catalogada como cistoadenoma hepático según la antigua clasificación.

Since the early reports in the literature, the nomenclature of hepatobiliary cystic lesions has been modified, with two types of lesions being described: serous and mucinous. In 2010, the World Health Organization established a new classification in which the terms hepatobiliary cystadenomas and cystadenocarcinomas were replaced by more specific entities such as mucinous cystic neoplasms and intraductal cystic tumors (intraductal papillary neoplasm, intraductal tubulopapillary neoplasm, and intraductal oncocytic papillary neoplasm). Regarding mucinous cystic neoplasms, the presence of ovarian stroma confers distinctive pathological and biological characteristics, which is a requirement in the WHO classification. This characteristic differentiates it from biliary hamartomas, congenital cysts, and Caroli's disease. Such neoplasms are rare, with an incidence of less than 5% of hepatic cystic lesions, and occur almost exclusively in women, often perimenopausal. Their potential for malignancy has been described, and this is the indication for surgical resection treatment. We present a clinical case of a patient with a mucinous cystic hepatic neoplasm, classified as a hepatic cystadenoma according to the old classification.

Plantar vein thrombosis: an uncommon cause of plantar foot pain / Trombose venosa plantar: uma causa incomum de dor em região plantar

INTRODUCTION: Plantar vein thrombosis is a rare condition that can lead to pain, edema, and walking difficulties. It presents a series of predisposing factors, such as recent surgeries, the use of oral contraceptives, and local trauma, among others. Imaging tests are essential for the right diagnosis, and ultrasonography is the modality of choice. As for treatment, there is no consensus in the literature. REPORT: Case of a 30-year-old patient who sought emergency medical care complaining of sudden severe pain in the plantar region of her right foot with walking difficulties. On physical examination, hyperalgesia was observed in the plantar region, irradiating to the calf, associated with swelling. Color Doppler imaging identified an acute thrombus in the medial plantar vein. Rivaroxaban was initially prescribed and replaced by acetylsalicylic acid after three months. The treatment was effective, and the patient was discharged after 11 months. CONCLUSION: Plantar vein thrombosis is a rare condition and has a wide range of differential diagnoses so physicians must maintain a high level of clinical suspicion. To improve diagnosis and treatment, it would be necessary to include plantar veins in the investigation protocols of patients suspected of having Deep Venous Thrombosis, besides additional clinical research for improving treatment.

INTRODUÇÃO: A trombose de veias plantares é uma condição rara que pode cursar com dor, edema e dificuldade na deambulação. Apresenta uma série de fatores predisponentes, como cirurgias recentes, uso de anticoncepcional oral, trauma local, entre outros. A realização de exame de imagem é essencial para o diagnóstico, sendo a ultrassonografia a modalidade de escolha. Quanto ao tratamento, não há consenso na literatura. RELATO: Relatamos o caso de uma paciente de 30 anos que procurou atendimento médico de urgência com queixa de dor de forte intensidade, súbita, em região plantar do pé direito com dificuldade de deambulação. Ao exame físico, observou-se hiperalgesia em região plantar com irradiação para panturrilha, associada a empastamento da mesma. O ecodoppler colorido identificou trombo agudo em veia plantar medial. Optou-se pela prescrição de rivaroxabana, a qual foi substituída por ácido acetilsalicílico após três meses. A paciente evoluiu bem e recebeu alta do tratamento após 11 meses. CONCLUSÃO: A trombose de veias plantares é rara e tem uma alta gama de diagnósticos diferenciais, de forma que o profissional médico deve manter um alto nível de suspeição clínica. Para aperfeiçoar seu diagnóstico e tratamento, seria necessária a inclusão das veias plantares aos protocolos de investigação de pacientes com suspeita de Trombose Venosa Profunda, e pesquisas clínicas que elucidassem os melhores métodos terapêuticos.

Circumpsoas block - an anterior myofascial plane block for lumbar plexus elements: case report

Abstract In an attempt to improvise the analgesia in patients with femoral fractures, we aimed at depositing local anesthetic deep to anterior psoas fascia (APf) under ultrasound (US) guidance to block lumbar plexus elements which emerge lateral, anterior, and medial to the psoas major muscle. We termed this as circumpsoas block (CPB). Clinical and computed tomography contrast studies revealed that a continuous CPB infusion with a catheter provided a reliable block of the lumbar plexus elements. No adverse were events noted. We conclude that US guided CPB is a reliable technique for managing postoperative pain after surgery of femur fractures.

Scorpion venom component: AGAP exhibits local anaesthetic effects and attenuates nociceptive pain

The incidences of systemic toxicity and other complications associated with existing local anaesthetics can occur at clinical concentration level and vary with the anaesthetic techniques, types of surgery and patient factors. This evidence suggests the need for therapeutic interventions in peripheral and regional anaesthesia. Buthus martensii Karsch (BmK) scorpion venom is a compound that contains mixtures of peptides that have analgesic properties. This study aimed to investigate the local anaesthetic activity of scorpion venom peptide, AGAP (analgesic-antitumor peptide) in mechanical hyperalgesia or acute inflammatory pain. Method: Formalin was injected into the left hind paw after 20 minutes of infiltration of drugs. The time of licking or flinching of the injected hind paw was recorded as indicative of nociceptive or acute inflammatory pain. Paw flinching or quick withdrawal was considered a positive response to pain in the partial sciatic nerve ligation. The paw-withdrawal threshold (PWT) was determined by consecutively increasing and decreasing the magnitude of the stimulus. Results: The results indicated that AGAP exhibited a 67.9% inhibition in licking or flinching time and an 88.1% inhibition in paw withdrawal in mechanical hyperalgesia. The addition of AGAP to lidocaine showed an 89.5% inhibition in paw withdrawal. Conclusion: The data presented in this study suggest that local infiltration of AGAP significantly reduced mechanical hyperalgesia and acute inflammatory pain

Management of acute testicular pain in children: changing trends with improvements in scrotal ultrasonography over 18 years

INTRODUCTION@#Doppler scrotal ultrasonography (US) is the modality of choice in diagnosing testicular torsion. We aimed to evaluate the performance of scrotal US in diagnosing testicular torsion over the past 18 years in our institution and determine the factors contributing to the length of wait times for it.@*METHODS@#A retrospective review was conducted of boys who presented with acute scrotal pain from 2014 to 2015. US reports, operative findings, final diagnosis and key time points of the patients' journey (time to emergency department consultation, time to admission, time to US and time to operating theatre [OT]) were collected. US performance results were compared with those observed in a historical cohort from 1998 to 2004. Wait times were compared between operated and non-operated patients.@*RESULTS@#Data from 519 boys with a mean age of 9.15 years was collected. Of these, 438 (84.4%) boys had undergone initial scrotal US; of these scrotal US cases, 28 were surgically explored, with 23 confirmed to have torsion. Another five cases were explored without prior US, and all were confirmed to have torsion. Performance analysis of US showed a sensitivity of 100% and a specificity of 98.8%. There was no significant difference between wait times of operated and non-operated patients. Time to US (P < 0.0001, r = 0.96) and time to OT (P < 0.0001, r = 0.64) correlated significantly with the total time from presentation to surgery.@*CONCLUSION@#There has been an improvement in the diagnostic performance of scrotal US for testicular torsion over the past 18 years. Quality improvement programmes targeted at reducing wait times for patients presenting with acute scrotum should target time to US and time to OT.

Visão integrativa da dor em seu aspecto biopsicossocial / Integrative view of pain in its biopsychosocial aspect / Visión integradora del dolor en su vertiente biopsicosocial

Na definição padrão da medicina a nocicepção ou algesia é a transdução, condução e processamento de sinais nervosos aferentes gerados por nociceptores estimulados,resultando na percepção da dor. Os sinais de estímulos nocivos (mecânicos, térmicos ou químicos) são transmitidos principalmente através de dois tipos de nervos. As terminações nervosas das pequenas fibras mielinizadas a delta e as fibras C não mielinizadas estão localizadas na pele, tecido subcutâneo, periósteo, articulações, músculos e vísceras. As fibras beta mielinizadas, as maiores, normalmente transmitem estímulos não nocivos, como toque, vibração, pressão, movimento e propriocepção. No entanto, a entrada não nociva dessas fibras pode ser incorretamente processada em um sistema nervoso central alterado, resultando na percepção da dor (alodinia).

Efficacy of opioids and non-opioid analgesics in the treatment of post procedure pain of burned patients: a narrative review

Abstract Introduction Burns are a common trauma that cause acute severe pain in up to 80% of patients. The objective of this narrative review is to evaluate the efficacy of opioids, non-steroidal anti-inflammatory drugs, paracetamol, gabapentinoids, ketamine, and lidocaine in the treatment of acute pain in burn victims. Methodology The databases explored were PubMed, Embase, ClinicalTrials, and OpenGrey. The included randomized, controlled clinical trials assessed the analgesic efficacy of these drugs on hospitalized patients, had no age limit, patients were in the acute phase of the burn injury and were compared to placebo or other analgesic drugs. Studies describing deep sedation, chronic opioid use, chronic pain, and patients taken to reconstructive surgeries were excluded. The Jadad scale was used to evaluate quality. Results Six randomized controlled clinical trials (397 patients) that evaluated the analgesic efficacy of fentanyl (n = 2), nalbuphine (n = 1), ketamine (n = 1), gabapentin (n = 1), and lidocaine (n = 1) to treat post-procedural pain were included. Fentanyl, nalbuphine, and ketamine were effective, while lidocaine was associated with a slight increase in reported pain and gabapentin showed no significant differences. Two studies were of high quality, one was of medium high quality, and three were of low quality. No studies on the efficacy of NSAIDs or paracetamol were found. Conclusion Evidence of efficacy is very limited. Fentanyl, nalbuphine, and ketamine seem to be effective for controlling acute pain in burn patients, whereas gabapentin and lidocaine did not show any efficacy.

Assessment of main complications of regional anesthesia recorded in an acute pain unit in a tertiary care university hospital: a retrospective cohort

Abstract Background Regional anesthesia has been increasingly used. Despite its low number of complications, they are associated with relevant morbidity. This study aims to evaluate the incidence of complications after neuraxial block and peripheral nerve block. Methods A retrospective cohort study was conducted, and data related to patients submitted to neuraxial block and peripheral nerve block at a tertiary university hospital from January 1, 2011 to December 31, 2017 were analyzed. Results From 10,838 patients referred to Acute Pain Unit, 1093(10.1%) had side effects or complications: 1039 (11.4%) submitted to neuraxial block and 54 (5.2%) to peripheral nerve block. The most common side effects after neuraxial block were sensory (48.5%) or motor deficits (11.8%), nausea or vomiting (17.5%) and pruritus (8.0%); The most common complications: 3 (0.03%) subcutaneous cell tissue hematoma, 3 (0.03%) epidural abscesses and 1 (0.01%) arachnoiditis. 204 of these patients presented sensory or motor deficits at hospital discharge and needed follow-up. Permanent peripheral nerve injury after neuraxial block had an incidence of 7.7:10,000 (0.08%). The most common side effects after peripheral nerve block were sensory deficits (52%) and 21 patients maintained follow-up due to symptoms persistence after hospital discharge. Conclusion Although we found similar incidences of side effects or even lower than those described, major complications after neuraxial block had a higher incidence, particularly epidural abscesses. Despite this, other serious complications, such as spinal hematoma and permanent peripheral nerve injury, are still rare.

Tendinitis cálcica atraumática de tendón extensor común del dedo medio: un caso infrecuente de dolor metacarpofalángico / Atraumatic calcium tendonitis of common extensor tendon of the middle finger: a rare case of metacarpophalangeal pain

Calcific tendinitis is a pathology characterized by the deposits of periarticular hydroxyapatite. Its pathophysiology is not completely known. It is clinically characterized by important inflammatory changes with incapacitating pain. It most commonly affects the shoulder joint and it rarely affects the hand and wrist. Given the unusual nature of this localization, we present the clinical case of a woman who developed calcific tendinitis of the third metacarpophalangeal muscle. We present the clinical evolution of the case, the treatments carried out, and a review of the literature related to this unusual localization of calcific tendinitis.

Musculoskeletal disorders in operator drivers in northwestern Namibia ­ associated factors and awareness

Background: Operator drivers are responsible for driving trackless heavy-duty mining or construction vehicles such as graders, dumpers, loaders, and bulldozers. They have an increased prevalence of musculoskeletal disorders (MSDs) due to the nature of their work. There is a paucity of data on MSDs and associated factors among operator drivers in Namibia. Objective: We assessed awareness of, and factors associated with, MSDs among operator drivers in the construction and mining industries in Namibia. Methods: In this cross-sectional study, questionnaires were administered to operator drivers, and managerial staff were interviewed, using a semi-structured interview guide. Data obtained were analysed using chi-square tests and binary logistic regression modelling. Results: 182 operator drivers completed the questionnaires, and 13 operator drivers' supervisors and managers were interviewed. Factors associated with MSDs were length of service for ≥ 10 years (OR 15.3, 95% CI 6.0­39.0), alcohol consumption (OR 2.8, 95% CI 1.1­6.7), lack of physical fitness activity (OR 8.8, 95% CI 3.8­20.4), and lack of awareness of MSDs (OR 3.1, 95% CI 1.3­7.3). Managerial staff were of the opinion that the operator drivers did not suffer from MSDs. Conclusion: We found health issues that are associated with MSDs among the operator drivers, impacting their general wellness and productivity. Monitoring of health and wellness of these workers by the companies is recommended. There is need to increase MSD awareness, personal protective equipment usage, ergonomics skills training, and physical fitness exercises for operator drivers. Employers are urged to adopt policies, and to design guidelines and interventions aimed at promoting occupational health and safety in this population.

Sex and age differences in sensory threshold for transcutaneous electrical stimulation / Diferenças de sexo e idade no limiar sensitivo para estimulação elétrica transcutânea

Abstract Introduction Pain is one of the main symptoms prevalent in most pathologies. Transcutaneous Electrical Nerve Stimulation (TENS) represents not only a therapeutic measure, but also a mean to quantify the neurosensory and pain perception in patients with chronic pain. Objective To evaluate the relationship between sex and age with neurosensory thresholds (sensory threshold and tolerance threshold) in the application of therapeutic current in patients with chronic pain. Methods Forty-five patients with chronic pain (30 women and 15 men) aged between 24 and 87 years were selected. Each patient answered the Individual Questionnaire, McGill Pain Questionnaire (MPQ) and Beck Depression Inventory (BDI). Subsequently, the electric current was applied, through which the sensory and pain thresholds were analyzed, as well as the perception of activation of the neurosensory pathways for each individual. Data were analyzed using the SPSS 24.0 for Windows. Results There was no significant correlation (p > 0.05) between a possible depressive diagnosis and the perception of current by the sensory and pain thresholds. Regarding sex, there was a significant difference in sensory thresholds (p = 0.003) between men and women, while no statistical differences were observed between sexes for pain complaint and pain threshold (p > 0.05). For the correlational analysis, a significant correlation (p = 0.05) was identified between the variables BMI and pain tolerance threshold (r = 0.68) for females and age and sensory threshold (r = 0.65) for males. Conclusion The sex and age variables are important in the measurement of TENS parameters because they lead to significant differences in sensory and pain thresholds.

Resumo Introdução A dor é um dos principais sintomas preva-lentes na maioria das patologias. A estimulação elétrica ervosa transcutânea (TENS) se apresenta não apenas como medida terapêutica, como também um meio de quantificar a percepção neurossensitiva e dolorosa em pacientes com dores crônicas. Objetivo Avaliar a relação entre sexo e idade com os limiares neurossensitivos (limiar sensitivo e limiar de tolerância) na aplicação da corrente terapêutica TENS, em pacientes com dores crônicas. Métodos Foram selecionados 45 pacientes com dores crônicas (30 mulheres), com idade entre 24 e 87 anos. Cada paciente respondeu ao Questionário Individual, ao Questionário McGill de Dor (MPQ) e ao Inventário de Depressão de Beck (BDI). Posteriormente, aplicou-se a corrente elétrica TENS, pela qual foram analisados o limiar sensitivo e doloroso, bem como a percepção de acionamento das vias neurossensitivas para cada indivíduo. Os dados foram analisados pelo pacote SPSS 24.0 for Windows. Resultados Não houve correlação significativa (p > 0,05) entre possível diagnós-tico depressivo e a percepção da corrente pelos limiares de sensibilidade e dor. Em relação ao sexo, houve diferença significativa nos limiares sensitivos (p = 0,003) entre homens e mulheres. Já para a queixa de dor e limiar de dor, não foram observadas diferenças estatísticas entre os sexos (p > 0,05). Para as análises correlacionais, identificou-se correlação significativa (p = 0,05) entre as variáveis de índice de massa corporal e limiar de tolerância à dor (r = 0,68) para o sexo feminino e idade e limiar sensitivo (r = 0,65) paro o sexo masculino. Conclusão As diferenças identificadas entre os limiares de sensibilidade entre os sexos, onde as mulheres identificaram o estímulo elétrico significativamente primeiro que os homens, podem auxiliar nas doses de intensidade ou tipo de corrente terapêutica dos pacientes.

Tratamento pré-hospitalar da dor traumática aguda: um estudo observacional / Tratamiento prehospitalario del dolor traumático agudo: un estudio observacional / Pre-hospital treatment of acute trauma pain: an observational study

Resumo Objetivo Descrever e analisar a eficácia das intervenções levadas a cabo pelos enfermeiros para reduzir a dor dos doentes com lesões traumáticas. Métodos Estudo de coorte prospetivo realizado junto das Ambulâncias de Suporte Imediato de Vida em Portugal, entre 1 de março de 2019 e 30 de abril de 2020. Foram recolhidos dados sobre o tipo de intervenções implementadas e sobre o tempo que durou a aplicação dos procedimentos de salvamento. De forma a poder estudar a evolução das dores traumáticas agudas, foi utilizada uma Escala de Classificação Numérica composta por 11 pontos. As alterações do nível de dor registadas ao longo dos três momentos de avaliação realizados foram estudadas utilizando modelos lineares mistos com interceptos aleatórios para se poder analisar as medidas repetidas aplicadas ao mesmo paciente. Estas alterações foram avaliadas antes e depois da aplicação das intervenções para alívio da dor. Resultados 596 pacientes foram incluídos neste estudo. A maioria era do sexo masculino (65,9%) e tinha média de idade de 53,05±19,72 anos. Houve redução na intensidade média da dor na ordem dos 2,44 pontos (p<0,005) entre o início e o fim da avaliação, e redução de 39,62% entre os pacientes que apresentavam nível de dor igual ou superior a 7 (46,7% contra 7,08%, p<0,05). As medidas que envolvem o uso de morfina, crioterapia e intervenções de suporte emocional provaram ser eficazes. As medidas de conforto como um todo não parecem ser capazes de ter um impacto significativo no alívio da dor. Conclusão As intervenções pré-hospitalares farmacológicas e não farmacológicas levadas a cabo pelos enfermeiros provaram ser eficazes na redução da dor. As medidas de conforto não provaram ser eficazes, pelo que o seu potencial deve ser repensado e reforçado.

Abstract Objective To describe and analyze the effectiveness of nurses' interventions in pain reduction among patients with traumatic injury. Methods Prospective cohort study conducted in the Immediate Life Support Ambulances in Portugal from March 1, 2019 to April 30, 2020. We have collected data on the kind of interventions implemented and the time elapsed during rescue procedures. To investigate the course of acute trauma pain, a 11-point Numeric Rating Scale was used. Changes in the level of pain registered throughout the three assessment moments were studied using linear mixed-effects models with random intercepts to account for the repeated measurements conducted on the same patient. These changes were assessed before and after the administration of the pain relief interventions. Results 596 patients were included in this study. Most of them were male (65.9%) and had a mean age of 53.05±19.72 years. There was a reduction in the average pain intensity of 2.44 points (p<0.005), between the beginning and end of the assessment, and a reduction of 39.62% among the patients who were experiencing a level of pain equal to or greater than 7 (46.7% vs 7.08%, p<0.05). Measures involving the use of morphine, cryotherapy and relationship-based measures have proven to be effective. Comfort measures as a whole do not seem to have a significant impact on pain relief. Conclusion Pre-hospital pharmacological and non-pharmacological nurses' interventions have proven to be effective in reducing pain. Comfort measures have not been proved to be effective, so their potential must be rethought and enhanced.

Intravenous lidocaine infusion for the treatment of acute pain in the pediatric intensive care unit: case series / Infusión de lidocaína endovenosa para el tratamiento de dolor agudo en la unidad de cuidado intensivo pediátrico: serie de casos

Abstract Introduction: The use of intravenous lidocaine infusion has increased over the past decade as part of a multimodal approach to analgesia in adults; however, information about its safety and tolerability in the pediatric population is limited. Methods: Acute pain management using lidocaine infusion in eleven patients treated in the pediatric intensive care unit. Results: Five cases of postoperative abdominal pain and six cases of non-operative abdominal pain. Two cases were cancer patients affected by neutropenic colitis. Analgesic control achieved was good. Conclusion: Lidocaine infusions are apparently a safe option for the management of acute pain, either post-operative or not, in the pediatric population.

Resumen Introducción: El uso de la infusión de lidocaína endovenosa ha aumentado en la última década como parte de un enfoque analgésico multimodal en los adultos; sin embargo, se dispone de información limitada sobre su seguridad y tolerabilidad en la población pediátrica. Métodos: Se presentan once casos de manejo de dolor agudo con lidocaína en infusión tratados en unidad de cuidado intensivo pediátrico. Resultados: Cinco casos fueron postoperatorio abdominal y seis casos tenían dolor abdominal no postoperatorio. Dos pacientes tenían cáncer y cursaban con colitis neutropénica. El control analgésico alcanzado fue bueno. Conclusión: Las infusiones de lidocaína parecen ser una opción segura para el manejo del dolor agudo ya sea posquirúrgico o no en la población pediátrica.

Validity and reliability of the Neonatal Infant Acute Pain Assessment Scale (NIAPAS) in Turkish: prospective study

ABSTRACT BACKGROUND: Using pain scales helps nurses in making early diagnoses and in assessing and managing pain symptoms and findings when developing a nursing care plan. OBJECTIVE: To determine the validity and reliability of the Turkish form of the Neonatal Infant Acute Pain Assessment Scale (NIAPAS). DESIGN AND SETTING: Prospective study conducted in Istanbul Bakırköy Dr. Sadi Konuk Training and Research Hospital, Istanbul, Turkey. METHODS: 145 newborns in the 26th to 42nd gestational weeks that were receiving treatment and care in the neonatal intensive care unit were included in this study. A total of 1740 pain assessments were made by two independent observers on these 145 newborns. The research data was collected using a newborn description form, NIAPAS and the Neonatal Infant Pain Scale (NIPS). RESULTS: The scope validity index of NIAPAS was found to be between 0.90 and 1.00 and its Cronbach's alpha coefficient was 0.914. Correlations between characteristics and total scores (r = 0.20-0.82) were found to be sufficiently high. In an assessment on concurrency validity, there was a strong positive relationship between NIAPAS and NIPS scores (r = 0.73-0.82; P < 0.000). From kappa analysis (0.73-0.99) and intraclass correlation (r = 0.75-0.96), it was determined that there was concordance between the observers. CONCLUSION: NIAPAS was found to be a valid and reliable scale for evaluating acute pain in newborns.

Metástasis de cáncer de mama como colangiocarcinoma perihiliar o lesión tipo Klatskin / Breast cancer metastasis as a cholangiocarcinoma or Klatskin-like lesion

Paciente de sexo femenino de 60 años de edad, con antecedente de carcinoma ductal de mama izquierda, presentó dolor agudo en epigastrio que se acompaña de 6 meses de dispepsia, saciedad precoz y pirosis; con una pérdida de 9 kilogramos en 2 meses. Refirió coluria, negó ictericia y acolia. Las pruebas de función hepática mostraron un patrón de colestasis con elevación de gama glutamiltrasferasa (GGT) y fosfatasa alcalina (FA). Fue diagnosticada con un Colangiocarcinoma perihiliar basado en hallazgos abdominales de tomografía y resonancia, con un nódulo parenquimatoso en el segmento 8 del hígado como un tumor infiltrante periductal. El diagnóstico presuntivo fue el de Tumor de Klatskin, pero la anatomía patológica fue compatible con metástasis de carcinoma ductal de mama (CK7 + / GATA3 +). El informe complementario mostró HER-2 negativo y estrógeno negativo (ER) y progesterona (PR) por lo que el inmunofenotipo final fue ER- / PR-; HER2- con índice de proliferación Ki67 <5%, una metástasis de cáncer de mama triple negativo.

A 60-year-old female, with a medical history of a ductal carcinoma of the left breast, presented with sharp pain in epigastrium with 6 months of dyspepsia, early satiety and pyrosis and with the loss of 9 kilograms in 2 months. She referred choluria and denied jaundice and acholia. Liver function tests showed a cholestasis pattern with only elevated Gama Glutamyl Teransferase and alkaline phosphatase. She was diagnosed with a hilar cholangiocarcinoma based on abdominal CT and MRI findings, with a parenchymal nodule in segment 8 of the liver as a periductal infiltrating tumor. The presumed diagnosis was Klatskin Tumor, but the biopsied site was compatible with breast ductal carcinoma metastasis (CK7 + / GATA3 +). The complementary report showed negative HER-2 and negative estrogen (ER) and progesterone (PR) so the final immunophenotype is ER- / PR-; HER2- with proliferation index Ki67 <5%, a triple-negative breast cancer metastasis.

Methylene Blue for the Treatment of Health Conditions: a Scoping Review

HIGHLIGHTS This scoping review summarizes the findings of clinical trials using methylene blue (MB) for the treatment of various health conditions. This research method allowed mapping main findings, clarifying research topics, and identifying gaps in the literature.

Abstract studies evaluating effective drugs for health conditions are of crucial importance for public health. Methylene blue (MB) is an accessible synthetic drug that presents low toxicity and has been used in several health areas due to its effectiveness. Objective: this scoping review aims to provide a comprehensive overview of relevant research regarding the use of MB for the treatment of health conditions. Methods: a five-stage framework Arksey and O'maley scoping review was conducted. The literature was searched in Cochrane Library database using Mesh term "methylene blue". Data were collected by two independent reviewers and submitted to descriptive synthesis. Results: The search resulted in 429 records, from which 16 were included after exclusion criteria were applied. The therapeutic use of MB was identified for acute conditions (malaria and septic shock), chronic conditions (discogenic back pain, bipolar disorder, refractory neuropathic pain, and post-traumatic stress disorder), and postoperative care (vasoplegic syndrome, and pain after haemorrhoidectomy, lumbar discectomy, and traumatic thoracolumbar fixation). Conclusion: there is much evidence emerging from clinical trials about the therapeutic use of MB for acute, chronic, and postoperative conditions; however, many gaps were identified, which open further avenues for future research.

Acute and chronic back pain in adults and elderly in southern Brazil: a population-based study / Dor aguda e crônica nas costas em adultos e idosos no sul do Brasil: um estudo de base populacional

Aims: to determine the prevalence of acute and chronic back pain and associated factors and identify the consequences of this pain in adults and the elderly in southern Brazil. Methods: cross-sectional study conducted in 2019, in Criciúma, Santa Catarina, in individuals aged 18 and over. Acute back pain was pain in the cervical, thoracic, or lumbar regions not exceeding 3 months and chronic pain as pain for 3 months or more. Bivariate analyzes and multinomial logistic regression were performed. Results: among the 820 participants, the prevalence of back pain was 67.0%, acute pain 39.3% (95% CI: 35.5% to 43.3%) and chronic pain 27.4% (95% CI: 24.5% to 30.4%). Acute back pain was associated with women, overweight, obesity, and with WMSD/RSI, while chronic pain chronic pain was found mostly in women, being related to leisure inactivity ...were female, leisure inactivity, falls, Work-related musculoskeletal disorder/repetitive strain injury, and arthritis/rheumatism. Conclusions: acute pain was greater among overweight/obese and chronic pain contribute to absenteeism and demand for health services.

Objetivos: determinar a prevalência de dores aguda e crônica nas costas e fatores associados e identificar as consequências dessas dores em adultos e idosos no Sul do Brasil. Métodos: estudo transversal realizado em 2019, em Criciúma, Santa Catarina, em indivíduos com 18 anos ou mais. Dor aguda foi a dor nas regiões cervical, torácica ou lombar não superior a três meses e dor crônica como dor por três meses ou mais. Foram realizadas análises bivariadas e regressão logística multinomial. Resultados: entre os 820 participantes, a prevalência de dor nas costas foi de 67,0%, dor aguda 39,3% (IC 95%: 35,5% a 43,3%) e dor crônica 27,4% (IC 95%: 24,5% a 30,4%). A dor aguda nas costas foi associada a mulheres, sobrepeso, obesidade e a distúrbio musculoesquelético relacionado ao trabalho/lesão por esforço repetitivo, enquanto a dor crônica, foi constatada majoritariamente em mulheres, tendo relação com sedentarismo, quedas, distúrbio musculoesquelético relacionado ao trabalho/lesão por esforço repetitivo e artrite/reumatismo. Conclusões: a dor aguda mais associada a excesso de peso/obesidade e a dor crônica contribuiu para o absenteísmo e procura pelos serviços de saúde.

Hipertensão ocular recorrente durante hemodiálise em paciente portador de glaucoma / Recurrent intraocular hypertension during hemodialysis in glaucoma patient

RESUMO A hipertensão ocular aguda durante a hemodiálise constitui evento raro e pode ser causa relevante de interrupção do tratamento dialítico devido à dor. Relata-se o caso de um paciente de 70 anos de idade, do sexo masculino, que apresentou quadros recorrentes de intensa dor ocular unilateral durante sessões dialíticas devido ao aumento de pressão intraocular. O paciente era portador de grave diminuição da acuidade visual no olho direito devido a glaucoma neovascular, controlado com medicação hipotensora tópica. Uma hora após o início da sessão dialítica, apresentou dor excruciante no olho direito, sendo necessário interromper o tratamento por diversas vezes. A dor somente era amenizada com uso de opioides por via endovenosa ou após cerca de 6 horas do procedimento. Injeção intraocular de drogas antiangiogênicas e acetazolamida por via oral, assim como tratamentos tradicionais para quadros agudos de hipertensão intraocular, como uso de hipotensor tópico e medicamentos hiperosmolares, foram insuficientes para o controle da dor. O problema se resolveu com ciclofotocoagulação transescleral realizada com laser diodo, com redução da pressão intraocular basal e controle da dor, o que permitiu a realização de sessões completas de hemodiálise. A base fisiopatológica desse evento incomum e suas opções terapêuticas são discutidas aqui.

ABSTRACT Acute ocular hypertension during hemodialysis is a rare event and may lead to interruption of dialytic therapy due to pain. A case of a 70-year-old male patient is reported, who presented recurrent intense unilateral ocular pain episodes during dialysis sessions for increased intraocular pressure. The patient presented with severely decreased visual acuity in the right eye due to neovascular glaucoma, which was controlled with topical hypotensive medication. One hour after initiating dialysis, he presented an excruciating pain on the right eye, which required interruption of treatment several times. Pain relief was possible only with intravenous opioids, or approximately 6 hours after dialysis. Intraocular injection of antiangiogenic drugs and per oris acetazolamide, as well as other traditional treatments for acute episodes of intraocular hypertension, such as topical antihypertensive agents and hyperosmotic medications, were not sufficient to control pain. The problem was solved with transscleral diode laser cyclophotocoagulation, which reduced baseline intraocular pressure and controlled pain, enabling complete hemodialysis sessions. The pathophysiological aspects and therapeutic options of this unusual condition are discussed.

Principais causas ginecológicas de dor pélvica aguda em mulheres / Main gynecological causes of acute pelvic pain in women

Este trabalho buscou reunir dados essenciais sobre as etiologias de dor pélvica aguda, uma queixa constante nos serviços de emergências e ambulatórios de ginecologia, responsável por grande desconforto e impacto na qualidade de vida de pacientes mulheres. É uma condição laboriosa por causa de seu amplo espectro de causas, devendo ser abordada com cuidado e atenção pelo profissional médico, o qual deve considerar os diversos diagnósticos diferenciais, sendo a ultrassonografia o exame de maior importância para auxiliar em seu diagnóstico. As principais etiologias não obstétricas podem ser não ginecológicas e ginecológicas; essas últimas são divididas em anexiais e uterinas. Entre as causas ginecológicas, devem- -se investigar cistos ovarianos, torções anexiais, leiomiomas, doença inflamatória pélvica, abscesso tubo-ovariano, dismenorreia e complicações de dispositivos intrauterinos. A maioria das causas tem tratamento eficaz, com retorno da função do órgão e melhora da qualidade de vida, sem complicações, especialmente se diagnosticada precocemente.(AU)

The aim of this study was to gather important data on acute pelvic pain etiologies, a usual complaint in the emergency services and gynecology outpatient clinics, responsible for great discomfort and impact on quality of life in female patients. It is a laborious condition due to its wide spectrum of causes, which needs to be approached with attention by the physician, who must consider all the possible diagnoses, being the ultrasonography the most important exam to detect it. The main non-obstetric etiologies can be non-gynecological and gynecological, which are separated in adnexal and uterine causes. Among the gynecological causes, ovarian cysts, adnexal torsions, leiomyomas, pelvic inflammatory disease, ovarian tube abscess, dysmenorrhea and complications of intrauterine devices should be investigated. Most causes can be effectively treated, with return of organ function and improved quality of life, without complications, especially if diagnosed early.(AU)
