The Role of Vitamin D in the Treatment of Carpal Tunnel Syndrome: Clinical and Electroneuromyographic Responses.

Carpal tunnel syndrome (CTS) is the most common cause of peripheral compressive neuropathy and consists of compression of the median nerve in the wrist. Although there are several etiologies, idiopathic is the most prevalent origin, and among the forms of treatment for CTS, conservative is the most indicated. However, despite the high prevalence in and impact of this syndrome on the healthcare system, there are still controversies regarding the best therapeutic approach for patients. Therefore, noting that some studies point to vitamin D deficiency as an independent risk factor, which increases the symptoms of the syndrome, this study evaluated the role of vitamin D supplementation and its influence on pain control, physical examination and response electroneuromyography to conservative treatment of carpal tunnel syndrome. For this, the sample consisted of 14 patients diagnosed with CTS and hypovitaminosis D, who were allocated into two groups. The control group received corticosteroid treatment, while the experimental group received corticosteroid treatment associated with vitamin D. Thus, from this study, it can be concluded that patients who received vitamin D, when compared to those who did not receive it, showed improvement in the degree of pain intensity, a reduction in symptom severity and an improvement in some electroneuromyographic parameters.

Effects of exercise-based interventions on gluteal tendinopathy. Systematic review with meta-analysis.

The objective of this review was to evaluate the effect of exercise on pain intensity, function, and quality of life in individuals with gluteal tendinopathy. Searches were carried out in PUBMED, EMBASE, CINAHL, Cochrane Library, and PEDro databases. Randomized or quasi-randomized controlled trials were included. Five studies met the eligibility criteria, comparing exercise-based interventions with minimal interventions and/or corticosteroid injections. Three studies, involving 383 participants, were included in the quantitative analysis. Meta-analyses showed that exercise is superior to minimal intervention for function in short-term [mean difference (MD) = 10.24; 95% confidence interval (95%CI) = 5.98, 14.50) and long-term (MD = 6.54; 95%CI = 1.88, 11.21]). However, no difference was observed for quality of life in the short [standardized mean difference (SMD) = 0.33; 95%CI = -0.29, 0.94] and long-term (SMD = 0.11; 95%CI = -0.16, 0.37). The effect of exercise was no different from that of corticosteroid injections for pain intensity in the short (MD = 1.25; 95%CI = -3.56, 6.05) and long-term (MD = -1.37; 95%CI = -3.72, 0.98]). In conclusion, exercise is superior to minimal interventions for function in the short- and long-term in individuals with gluteal tendinopathy. Exercise and corticosteroid injections had similar effects on pain intensity, however, exercise showed a higher treatment success rate when compared to corticosteroid injections in this population. The GRADE analysis revealed that the certainty of the evidence ranges from low to very low, therefore, large high-quality randomized controlled trials are recommended.PROSPERO registration number: CRD42021242853.

Efficacy of ozone injections for reducing musculoskeletal pain in comparison with corticosteroid injections: A systematic review and meta-analysis.

BACKGROUND: Corticosteroid injections are frequently used in the short-term treatment of musculoskeletal pain, but their use is controversial as repeated exposures to corticosteroids can lead to deleterious effects on musculoskeletal tissue. Ozone injections have been proposed as a possible treatment for musculoskeletal pain; however, their effectiveness has not been compared with corticosteroids. OBJECTIVE: To evaluate the effectiveness of ozone injections for reducing pain in individuals with musculoskeletal pain in comparison with corticosteroid injections through a meta-analysis. METHODS: An online systematic search was performed using electronic databases up to September 2023. We searched for studies that compared corticosteroid injections with ozone injections in the treatment of musculoskeletal pain of diverse origins. RESULTS: Eleven studies were included comprising a total of 534 individuals. In the overall pooled analysis, a pain reduction in favor of corticosteroid injections was found in the short term (d= 0.31, 95% CI 0.01 to 0.60, p (z) 0.04, I2 = 32%). In the medium term, no significant differences were found in reducing pain between groups (d=-0.17, 95% CI -0.42 to 0.07, p (z) 0.15, I2 = 0%). CONCLUSIONS: Our results suggest that corticosteroids injections are more effective in reducing musculoskeletal pain in the short term, but equally effective in the medium term when compared with ozone injections. Nonetheless, better-quality clinical trials are necessary to corroborate these results.

Doxofylline as a steroid-sparing treatment in Mexican children with asthma.

OBJECTIVE: The aim of this pilot study was to assess the efficacy of doxofylline as an ICS-sparing agent in the treatment of Mexican children with asthma. METHODS: 10-week, open-label, crossover, pilot study, we examined the steroid-sparing effect of doxofylline in Mexican children with asthma. Patients aged 6-16 years treated with inhaled corticosteroids (ICS) for at least 8 wk before enrollment were divided randomly into two groups at the baseline visit. Group A (n = 31) received doxofylline (18 mg/kg/day) plus standard-dose budesonide (D + SDB) for the first 4-week period followed by doxofylline plus reduced-dose budesonide (D + RDB) for the second 4-week period. Group B (n = 30) received D + RDB followed by D + SDB. Clinical outcomes assessed included lung function (forced expiratory volume; in 1 s, FEV1), fractional exhaled nitric oxide (FeNO), asthma control, number of exacerbations and use of rescue medication (salbutamol). RESULTS: It was shown that combined use of doxofylline and ICS may allow children with asthma to reduce their daily dose of ICS while maintaining lung function and improving asthma control (p = 0.008). There were few asthma exacerbations and only one patient required treatment with systemic corticosteroids. Rescue medication use decreased significantly in patients receiving D + SDB during the first 4-week period. CONCLUSIONS: Our results suggest that doxofylline may be a steroid-sparing treatment in asthma, but longer-term, controlled studies are needed to confirm these observations.

Neumonía por Pneumocystis jirovecii asociada a hemorragia alveolar difusa en un paciente con trasplante renal / Pneumocystis jirovecii pneumonia associated with diffuse alveolar hemorrhage in a renal transplant patient. Case report

La neumonía por Pneumocystis jirovecii es una enfermedad fúngica oportunista descrita principalmente en pacientes con VIH, sin embargo, tras la introducción de la TARV, ha incrementado su incidencia en pacientes con inmunosupresión no asociada a VIH, como neoplasias hematológicas y trasplantes de órganos sólidos. Presentamos el caso de un varón de 17 años, receptor de un trasplante renal, con inmunosupresión prolongada con corticoesteroides, con cuadro clínico de tos, disnea y fiebre. La TC mostró micronódulos pulmonares centrolobulillares y vidrio esmerilado. El LBA fue compatible con hemorragia alveolar difusa (HAD), con RPC positiva para P. jirovecii. Se descartaron otras infecciones y enfermedades autoinmunes. Recibió tratamiento con cotrimoxazol con buena evolución clínica y mejoría radiológica. Si bien las causas más frecuentes de HAD son etiologías autoinmunes como enfermedades reumatológicas o vasculitis, es prioritario descartar causas infecciosas, incluyendo P. jirovecii, ya que el tratamiento dirigido puede tener un impacto significativo en la mortalidad en este grupo de pacientes.

Pneumocystis jirovecii pneumonia is an opportunistic fungal infection, described mainly in HIV patients, however, after the introduction of ART, its presentation has increased in patients with non-HIV immunosuppression, such as hematological cancers, solid or hematopoietic stem cell transplantation. We report the case of a 17-year-old male, kidney transplant patient, with prolonged immunosuppression with corticoesteroids, with history of cough, dyspnea, and fever. Chest CT evidences centrilobular pulmonary micronodules with ground glass. BAL was performed compatible with diffuse alveolar hemorrhage, with positive PCR for P. jirovecii. Other infections and autoimmune disease were ruled out. He received treatment with cotrimoxazole with clinical improvement of the patient, and follow up chest CT at the end of treatment showed decrease of pulmonary infiltrates. Although the most frequent causes of DAH are autoimmune etiologies such as rheumatic diseases or vasculitis, it is a priority to rule out infectious causes, including P. jirovecii, since targeted treatment could have a significant impact on mortality outcomes in this group of patients.

Actualización del consenso chileno SOCHINEP-SER para el manejo de las sibilancias recurrentes del preescolar / Update of the chilean consensus SOCHINEP-SER for the management of recurrent wheezing in preschool children

Las sibilancias recurrentes del preescolar son un problema prevalente. 50% de todos los niños tiene al menos un episodio de sibilancias en los primeros 6 años. Sin embargo, solo 4 % de los menores de 4 años tiene diagnóstico de asma. Por este motivo es fundamental realizar una adecuada anamnesis y examen físico tendientes a descartar causas secundarias, lo que debe ser complementado con exámenes de laboratorio de acuerdo con la orientación clínica. En la actualidad se recomienda indicar tratamiento de mantención con corticoides inhalados en aquellos niños que tengan episodios repetidos de obstrucción bronquial y que tengan una alta probabilidad de respuesta favorable a esta terapia. Se ha demostrado que aquellos pacientes que tienen un recuento de eosinófilos en sangre > 300 células por mm3 o aquellos que presentan una prueba cutánea positiva o IgE específicas positivas para alérgenos inhalados, responderán adecuadamente al tratamiento con esteroides inhalados.

Recurrent wheezing in preschoolers has a high prevalence. 50% of all children have at least one wheezing episode in the first six years of life. However, only 4% of children under four years of age are diagnosed with asthma. Therefore, it is essential to carry out an adequate medical history and physical examination to rule out secondary causes, which must be complemented with laboratory tests in accordance with clinical guidance. It is recommended to indicate maintenance treatment with inhaled corticosteroids to those children who have repeated episodes of wheezing and who have a high probability of a good response to this therapy. It has been demonstrated that those patients who have blood eosinophil count > 300 cells per mm3 or those who have a positive skin test or positive specific IgE for inhaled allergens will have a good response to inhaled corticosteroids.

Protocolo clínico ­ Manejo das exacerbações pulmonares agudas da fibrose cística / Clinical protocol ­ Management of acute pulmonary exacerbations of cystic fibrosis

A fibrose cística é uma desordem genética de caráter multissistêmico originada por variações no gene CFTR, que é responsável pela síntese da proteína homônima conhecida como "cystic fibrosis transmembrane conductance regulator", localizado no cromossomo 7. A manifestação predominante da doença é pulmonar, que se mantém como a principal causa de morbidade e mortalidade entre os indivíduos acometidos. As crises de exacerbação pulmonar se caracterizam por episódios de agravamento abrupto do quadro respiratório, demandando intervenção médica imediata, visto que tais episódios podem ocasionar danos irreversíveis e deterioração da função pulmonar, mesmo após a resolução dos sintomas agudos. O propósito do presente estudo foi a elaboração de um protocolo clínico direcionado ao manejo da exacerbação pulmonar aguda em pacientes portadores de fibrose cística, para ser implementado Hospital do Servidor Público Municipal. O protocolo proposto repousa sobre quatro pilares: continuidade ou intensificação do tratamento crônico em curso, emprego criterioso de corticosteroides em situações específicas, utilização de suporte ventilatório apropriado e seleção de terapêuticas antivirais e antimicrobianas. Palavras-chave: Fibrose cística. Exacerbação pulmonar. Antimicrobianos. Antivirais. Suporte ventilatório.

Inclusão de nova apresentação de omalizumabe (150 mg/mL) solução injetável em seringa preenchida para tratamento da asma alérgica grave não controlada apesar do uso de corticoide inalatório (CI) associado a um beta2- agonista de longa ação (LABA) / Inclusion of new presentation of omalizumab (150 mg/mL) solution for injection in pre-filled syringe for treatment of severe allergic asthma that is uncontrolled despite use of inhaled corticosteroids (ICS) associated with a beta2- long-acting agonist (LABA)

INTRODUÇÃO: A asma é uma doença inflamatória crônica das vias aéreas inferiores que se caracteriza por aumento da responsividade dessas vias a diferentes estímulos, com consequente obstrução ao fluxo aéreo, de forma recorrente e reversível. A OMS estima que cerca de 235 milhões de pessoas sofrem de asma. No Brasil, a asma foi a 3ª causa de internação hospitalar pelo SUS em 2008, com cerca de 300.000 hospitalizações naquele ano. Em 2013, ocorreram 129.728 internações e 2.047 mortes. Já em 2018, o número de internações foi de aproximadamente 87.000. De acordo com o PCDT de asma, do Ministério da Saúde, o omalizumabe é uma terapia inespecífica anti-IgE indicada exclusivamente para adultos e crianças com pelo menos 6 anos de idade com asma alérgica, moderada a grave (etapas IV e V), cujos sintomas são inadequadamente controlados apesar do uso de corticoide inalatório associado a um beta-2 agonista de longa ação.

Effect of the combination of photobiomodulation therapy and the intralesional administration of corticoid in the preoperative and postoperative periods of keloid surgery: A randomized, controlled, double-blind trial protocol study.

Keloid scars are characterized by the excessive proliferation of fibroblasts and an imbalance between the production and degradation of collagen, leading to its buildup in the dermis. There is no "gold standard" treatment for this condition, and the recurrence is frequent after surgical procedures removal. In vitro studies have demonstrated that photobiomodulation (PBM) using the blue wavelength reduces the proliferation speed and the number of fibroblasts as well as the expression of TGF-ß. There are no protocols studied and established for the treatment of keloids with blue LED. Therefore, the purpose of this study is to determine the effects of the combination of PBM with blue light and the intralesional administration of the corticoid triamcinolone hexacetonide on the quality of the remaining scar by Vancouver Scar Scale in the postoperative period of keloid surgery. A randomized, controlled, double-blind, clinical trial will be conducted involving two groups: 1) Sham (n = 29): intralesional administration of corticoid (IAC) and sham PBM in the preoperative and postoperative periods of keloid removal surgery; and 2) active PBM combined with IAC (n = 29) in the preoperative and postoperative periods of keloid removal surgery. Transcutaneous PBM will be performed on the keloid region in the preoperative period and on the remaining scar in the postoperative period using blue LED (470 nm, 400 mW, 4J per point on 10 linear points). The patients will answer two questionnaires: one for the assessment of quality of life (Qualifibro-UNIFESP) and one for the assessment of satisfaction with the scar (PSAQ). The team of five plastic surgeons will answer the Vancouver Scar Scale (VSS). All questionnaires will be administered one, three, six, and twelve months postoperatively. The keloids will be molded in silicone prior to the onset of treatment and prior to excision to assess pre-treatment and post-treatment size. The same will be performed for the remaining scar at one, three, six, and twelve months postoperatively. The removed keloid will be submitted to histopathological analysis for the determination of the quantity of fibroblasts, the organization and distribution of collagen (picrosirius staining), and the genic expression of TGF-ß (qPCR). All data will be submitted to statistical analysis. Trial registration: This study is registered in ClinicalTrials.gov (ID: NCT04824612).

Ultrasound-guided Procedures Allow Delay of Definitive Treatment for Core Muscle Injuries.

INTRODUCTION: Core muscle injuries (CMI) are common in every sport. To minimize lost playing time, providers apply various nonsurgical treatments, including platelet-rich plasma, corticosteroids, ultrasound (US)-guided percutaneous tenotomy, and prolotherapy. Limited data exist with regard to their effectiveness. We chose to review a cohort of consecutive professional and collegiate athletes who sustained CMI at various points within their seasons and underwent a combination of US-guided percutaneous needle "tenotomy" and corticosteroid injections to complete the remainder of their seasons. METHODS: Twenty-five consecutive collegiate or professional athletes with CMI involving the rectus abdominis-adductor aponeurotic plate were included in this retrospective study. Athletes with concomitant symptomatic hip femoroacetabular impingement were included in the study. The primary outcome measure was whether athletes completed their seasons. Secondary measures were weeks played after the procedures (delay until surgery), need for repeat procedures, and outcomes after eventual surgery. Postoperative performance was assessed via interviews at 6 wk and 6 months postoperatively. RESULTS: Twenty-one of 25 (84%) athletes completed their seasons. On average, athletes returned to play 3 d (range, 1-9 d) after the procedures. Surgical repair was delayed a mean of 18 wk (range, 2-44 wk). Seven athletes had concomitant symptomatic femoroacetabular impingement and six underwent combined hip arthroscopy and core muscle repairs. Among 17 patients who eventually had core muscle surgery alone (no hip surgery), 82% (14 of 17) reported performing at their preinjury level at 6 wk. At 6 months, 96% of postop athletes (22 of 23) reported performing at their preinjury level. CONCLUSIONS: Temporizing CMI with US-guided percutaneous tenotomy and corticosteroid injections is effective in allowing continued sport participation among high-level athletes and does not negatively affect postoperative outcomes.

Stellate ganglion block as an analgesic rescue alternative in phantom limb syndrome following an amputation: A case report / Bloqueo del ganglio estrellado como alternativa de rescate analgésico en síndrome de miembro fantasma doloroso postamputational: Un reporte de caso

Phantom limb syndrome (PLS) is a condition that occurs in amputee patients that has a wide array of different treatment approaches. We present the case of a patient diagnosed with complex regional pain syndrome (CRPS) of the right upper limb secondary to polytrauma with complete brachial plexus injury, who, after being subjected to multiple successful therapies, was finally taken to amputation. Later, he developed a painful PLS that was difficult to manage, which was treated with a stellate ganglion block (SGB), achieving a significant decrease in pain. This article aims to present a case in which a SGB was used as an adjunct to control acute postoperative PLS in a patient with previous sensitization due to CRPS. The SGB, in this case, performed with local anesthetic plus corticosteroid, constitutes a useful therapeutic alternative for intense postoperative pain in PLS, achieving adequate pain relief without adverse effects. However, its routine use as in acute postoperative pain still lacks sufficient evidence for complete support, therefore we urge the scientific community to undertake more in-depth research concerning this topic in order to create clear guidelines and recommendations.

El síndrome del miembro fantasma (PLS, por sus siglas en inglés) es una condición que se presenta en pacientes amputados con un campo extenso para los diferentes enfoques de tratamiento. Presentamos el caso de un paciente diagnosticado con síndrome complejo de dolor regional (SCDR) del miembro superior derecho secundario a politraumatismo con lesión completa del plexo braquial, quien, tras ser sometido a múltiples tratamientos exitosos, fue finalmente llevado a amputación. Posteriormente, desarrolló un PLS doloroso de difícil manejo, el cual fue tratado con un bloqueo del ganglio estrellado (BGE), logrando una disminución significativa del dolor. Este artículo tiene como objetivo presentar un caso en el que se utilizó un BGE como coadyuvante para el control del PLS en el posoperatorio de manera aguda en un paciente con sensibilización previa por SCDR. EL BGE, en este caso, realizado con anestésico local más corticosteroide, constituye una alternativa terapéutica útil para el dolor posoperatorio intenso en PLS, consiguiendo un adecuado alivio del dolor sin efectos adversos. Sin embargo, su uso rutinario como en el dolor postoperatorio agudo, aún carece de evidencia suficiente para un respaldo completo, por lo que invitamos a la comunidad científica a realizar una investigación más profunda sobre este tema para crear pautas y recomendaciones claras.

Trichosporon asahii superinfections in critically ill COVID-19 patients overexposed to antimicrobials and corticosteroids.

OBJECTIVES: To investigate the occurrence of Trichosporon asahii fungemia among critically ill COVID-19 patients. METHODS: From 1 July to 30 September 2020, cases of T asahii fungemia (TAF) in a Brazilian COVID-19 referral centre were investigated. The epidemiology and clinical courses were detailed, along with a mycological investigation that included molecular species identification, haplotype diversity analysis and antifungal susceptibility testing. RESULTS: Five critically ill COVID-19 patients developed TAF in the period. All five patients had common risk conditions for TAF: central venous catheter at fungemia, previous exposure to broad-spectrum antibiotics, prior echinocandin therapy and previous prolonged corticosteroid therapy. The average time of intensive care unit hospitalisation previous to the TAF episode was 23 days. All but one patient had voriconazole therapy, and TAF 30-day mortality was 80%. The five T asahii strains from the COVID-19 patients belonged to 4 different haplotypes, mitigating the possibility of skin origin and cross-transmission linking the 5 reported episodes. The antifungal susceptibility testing revealed low minimal inhibitory concentrations for azole derivatives. CONCLUSIONS: Judicious prescription of antibiotics, corticosteroids and antifungals needs to be discussed in critically ill COVID-19 patients to prevent infections by hard-to-treat fungi like T asahii.

Mecanismos de acción de agentes propuestos para el tratamiento farmacológico específico de la infección por SARS-CoV-2 / Mechanisms of action of proposed agents for the specific pharmacological treatment of SARS-CoV-2 infection

Resumen Desde la notificación de la pandemia por SARS-CoV-2, agente patógeno responsable del COVID-19, muchos de los tratamientos dirigidos a su manejo han estado sometidos a estudios de manera constante, con el fin de comprobar su eficacia y seguridad. El conocimiento de su virología y etiopatogenia posibilitaría objetivar los pasos moleculares específicos que puedan ser blancos terapéuticos de variados fármacos actualmente disponibles. Esta experiencia proviene principalmente de las infecciones por SARS-CoV y MERS-CoV, con resultados variados 'in vitro' en el SARS-CoV-2, sin evidencia clínica que demuestre efectividad y seguridad de dichos tratamientos. A la fecha, no se ha podido concretar con claridad un esquema de tratamiento específico, debido a que la evidencia surgida ha puesto en jaque cada uno de los fármacos propuestos. Esto ha motivado a continuar en la búsqueda de una estrategia efectiva que permita manejar esta pandemia con la seguridad y eficacia necesaria para que el beneficio terapéutico esté por sobre los posibles efectos adversos que estos esquemas farmacológicos pudiesen presentar. La siguiente revisión pretende mostrar la evidencia disponible a la fecha, definiendo la actividad de cada fármaco en función de su mecanismo de acción.

Since the beginning of the pandemic by SARS-CoV-2, the pathogen responsible for COVID-19, many of the therapeutic options for its management have been under constant revision, in order to verify their safety and efficiency. Knowledge of the viral structure and pathogenesis make it possible to determine the molecular pathways that may be targeted with current available drugs. The experience with these drugs comes mainly from infections caused by SARS-CoV and MERS-CoV, in vitro studies with SARS-CoV-2 that yield variable results, and clinical experience that does not ensure effectiveness and safety of such drugs. To date, it has not been possible to elucidate a specific treatment scheme, because of the constant release of evidence that challenges the usefulness of the proposed drugs. This has motived us to continue seeking for an effective strategy that allows to manage this pandemic in a safe and efficient manner, so that therapeutic benefit surpasses the related adverse drug reactions that can occur. The following review aims to showcase the evidence available to date by defining the activity of each drug based on its mechanism of action.

Is there a Role for Antenatal Corticosteroids in Term Infants before Elective Cesarean Section?

OBJECTIVE: Cesarean section (CS) delivery, especially without previous labor, is associated with worse neonatal respiratory outcomes. Some studies comparing neonatal outcomes between term infants exposed and not exposed to antenatal corticosteroids (ACS) before elective CS revealed that ACS appears to decrease the risk of respiratory distress syndrome (RDS), transient tachypnea of the neonate (TTN), admission to the neonatal intensive care unit (NICU), and the length of stay in the NICU. METHODS: The present retrospective cohort study aimed to compare neonatal outcomes in infants born trough term elective CS exposed and not exposed to ACS. Outcomes included neonatal morbidity at birth, neonatal respiratory morbidity, and general neonatal morbidity. Maternal demographic characteristics and obstetric data were analyzed as possible confounders. RESULTS: A total of 334 newborns met the inclusion criteria. One third of the population study (n = 129; 38.6%) received ACS. The present study found that the likelihood for RDS (odds ratio [OR] = 1.250; 95% confidence interval [CI]: 0.454-3.442), transient TTN (OR = 1.,623; 95%CI: 0.556-4.739), and NIUC admission (OR = 2.155; 95%CI: 0.474-9.788) was higher in the ACS exposed group, although with no statistical significance. When adjusting for gestational age and arterial hypertension, the likelihood for RDS (OR = 0,732; 95%CI: 0.240-2.232), TTN (OR = 0.959; 95%CI: 0.297-3.091), and NIUC admission (OR = 0,852; 95%CI: 0.161-4.520) become lower in the ACS exposed group. CONCLUSION: Our findings highlight the known association between CS-related respiratory morbidity and gestational age, supporting recent guidelines that advocate postponing elective CSs until 39 weeks of gestational age.
