Identificación del alelo HLA B*57: 01 en una población militar, de Lima-Perú / Identification of the allele HLA B*57: 01 in a military population, from Lima-Peru

El alelo HLA B*57:01 es un marcador genético asociado con la hipersensibilidad al fármaco anti-retroviral abacavir (ABC) y su frecuencia en la población peruana todavía es desconocida. El objetivo fue identificar el alelo HLA B*57:01 en una población militar de Lima, Perú. Se reclutaron 43 personas viviendo con VIH (PVV) quienes aceptaron participar a través de un consentimiento informado. La detección del alelo HLA B*57:01 se realizó mediante RPC en tiempo real (RT-PCR). Asimismo, se determinó la carga viral (CV), el recuento de linfocitos CD4 y la genotipificación del VIH. Se identificaron dos casos positivos al alelo HLA B*57:01 (4,7%). Además, uno de ellos presentó múltiples mutaciones de resistencia a los anti-retrovirales (ARV), incluyendo ABC. Se demostró por primera vez en el Perú la presencia del alelo HLA B*57:01.

The HLA B*57:01 allele is a genetic marker associated with hypersensitivity to the antiretroviral Abacavir (ABC) and its frequency in the Peruvian population is still unknown. The objective was to identify the HLA B*57:01 allele in a military population from Lima, Peru. Forty three people living with HIV (PLWH) were recruited, who agreed to participate through informed consent. Detection of the HLA B*57:01 allele was performed by real-time PCR (RT-PCR). Likewise, viral load (VL), CD4 lymphocyte count and HIV genotyping were determined. Two cases positive for the HLA B*57:01 allele (4.7%) were identified. In addition, one of them had multiple resistance mutations to antiretrovirals (ARVs), including ABC. The presence of the HLA B*57:01 allele was demonstrated for the first time in Peru.

Prótesis colónicas en el tratamiento paliativo del cáncer colónico. Nuestra evaluación tras 10 años de experiencia / Self-expanding metal stents in the palliative treatmentof coloncancer. Results of 10 years of experience

Introducción: la colocación de prótesis metálicas autoexpansibles (PAE) por vía endoscópica surge como opción terapéutica para la obstrucción colónica neoplásica en dos situaciones: como tratamiento paliativo y como puente a la cirugía curativa. Este procedimiento evita cirugías en dos tiempos y disminuye la probabilidad de colostomía definitiva y sus complicaciones con el consecuente deterioro de la calidad de vida. Objetivo: comunicar nuestra experiencia en la colocación de PAE para el tratamiento paliativo de la obstrucción colorrectal neoplásica. Diseño: retrospectivo, longitudinal, descriptivo y observacional. Material y métodos: se incluyeron todos los pacientes a quienes el mismo grupo de endoscopistas les colocó PAE con intención paliativa por cáncer colorrectal avanzado entre agosto de 2008 y diciembre de 2019. Fueron analizadas las variables demográficas y clínicas, el éxito técnico y clínico, las complicaciones tempranas y tardías y la supervivencia. Resultados: se colocó PAE en 54 pacientes. La media de edad fue 71 años. El 85% de las lesiones se localizó en el colon izquierdo. En el 57% de los pacientes se realizó en forma ambulatoria. El éxito técnico y clínico fue del 92 y 90%, respectivamente y la supervivencia media de 209 días. La tasa de complicaciones fue del 29,6%, incluyendo un 14,8% de obstrucción y un 5,6% de migración. La mortalidad tardía atribuible al procedimiento fue del 5,6%, ocasionada por 3 perforaciones tardías: 2 abiertas y 1 microperforación con formación de absceso localizado. Conclusiones: la colocación de PAE como tratamiento paliativo de la obstrucción neoplásica colónica es factible, eficaz y segura. Permitió el manejo ambulatorio o con internación breve y la realimentación temprana, mejorando las condiciones para afrontar un eventual tratamiento quimioterápico paliativo. Las mayoría de las complicaciones fueron tardías y resueltas endoscópicamente en forma ambulatoria. (AU)

Introduction: endoscopic placement of self-expanding metal stents (SEMS) emerges as a therapeutic option for neoplastic obstruction of the colon in two situations: as palliative treatment and as a bridge to curative surgery. This procedure avoids two-stage surgeries and reduces the probability of permanent colostomy and its complications with the consequent deterioration in quality of life. Objective: to report our experience in the placement of SEMS as palliative treatment in neoplastic colorectal obstruction. Design: retrospective, longitudinal, descriptive and observational study. Methods: all patients in whom the same group of endoscopists performed SEMS placement with palliative intent for advanced colorectal cancer between August 2008 and December 2019 were analyzed. Data collected were demographic and clinical variables, technical and clinical success, early and late complications, and survival. Results: SEMS were placed in 54 patients. The average age was 71 years. Eighty-five percent were left-sided tumors. In 57% of the patients the procedure was performed on an outpatient basis. Technical and clinical success was 92 and 90%, respectively, and median survival was 209 days. The complication rate was 29.6%, including 14.8% obstruction and 5.6% migration. Late mortality attributable to the procedure was 5.6%, caused by 3 late perforations: 2 open and 1 microperforation with localized abscess formation. Conclusions: The placement of SEMS as a palliative treatment for neoplastic colonic obstruction is feasible, effective and safe. It allowed outpa-tient management or brief hospitalization and early refeeding, improving the conditions to face an eventual palliative chemotherapy treatment. Most complications were late and resolved endoscopically on an outpatient basis. (AU)

Complicaciones perianales causadas por agentes modeladores inyectados en glúteos / Perianal complications caused by gluteal injection of modeling agents

En este reporte presentamos tres pacientes en quienes ocurrieron condiciones inflamatorias perianales tardías, luego de la administración de sustancias modeladoras no identificadas en los glúteos. El diagnóstico inicial y supuesto no fue correcto, ya que no se investigó durante la evaluación preliminar el antecedente de la administración de elementos modeladores. Recomendamos que los pacientes con patologías inflamatorias del ano, sobre todo aquellos cuyo curso es extraño, se les pregunte acerca de la administración de agentes modeladores en los glúteos. Esta práctica puede contribuir a la eficacia del diagnóstico de manifestaciones perianales caracterizadas por flogosis, que se presentan de forma inusual. (AU)

In this report we present three patients in which late perianal inflammatory conditions occurred after administration of unidentified modeling agents to the buttocks. The initial diagnosis was not correct because of the administration of modeling agents was not investigated during the initial eval-uation. We recommend inquiring patients with inflammatory pathologies of the anus, especially those whose course is unusual, about the adminis-tration of modeling agents to the buttocks. This approach can contribute to the efficiency of the diagnosis of perianal complaints characterized by inflammation, but rare in its appearance. (AU)

Duración de la diarrea aguda infecciosa con el uso de leche deslactosada vs leche con lactosa en la población pediátrica: Revisión sistemática / Duration of acute infectious diarrhea with the use of lactose-free milk vs. lactose-containing milk in the pediatric population: A systematic review

Introducción: La diarrea aguda es una entidad frecuente en pediatría, constituyendo una de las principales causas de mortalidad en países en desarrollo y en niños menores de cinco años. Si bien la alimentación representa uno de los pilares fundamentales en el tratamiento de la misma, no existe consenso entre los profesionales en cuanto a la indicación de leche deslactosada durante el curso del cuadro. Objetivos: Realizar una revisión sistemática para estudiar el impacto del consumo de leche deslactosada vs leche regular en la duración de la diarrea aguda infecciosa en niños. Materiales y métodos: Se realizó una revisión sistemática incluyendo artículos publicados desde el año 2008 al 2023, utilizando para la búsqueda las bases de datos PubMed, Lillacs, Cochrane Library y literatura gris. Se incluyeron estudios experimentales, observacionales, revisiones, guías de atención y metaanálisis, realizados en pacientes pediátricos sin patologías de base, cursando cuadro de diarrea aguda infecciosa, que compararan el uso de leche deslactosada frente a leche regular. Resultados: Se seleccionaron doce artículos. En 9 de ellos se constató una disminución en la duración de la diarrea en los pacientes que recibieron leche deslactosada con una diferencia de medias de 18 horas (en un rango entre 4 y 32.6 horas). No se reportaron diferencias estadísticamente significativas en la mortalidad entre el uso de una u otra fórmula láctea. En relación al uso de una u otra fórmula no se objetivaron variaciones en el peso estadísticamente significativas. La necesidad de hospitalización fue similar entre ambos grupos. Solo un artículo analizó la frecuencia o volumen de deposiciones sin encontrar diferencias significativas (AU)

Introduction:Acute diarrhea is frequent in pediatrics, and constitutes one of the main causes of mortality in developing countries and in children under five years of age. Although feeding is one of the fundamental pillars in the treatment of diarrhea, there is no consensus among professionals regarding the indication of lactose-free milk during the course of the symptoms. Objectives: To conduct a systematic review to study the impact of lactose-free milk vs. regular milk consumption on the duration of acute infectious diarrhea in children. Materials and methods: A systematic review was conducted including articles published between 2008 and 2023, using PubMed, Lillacs, Cochrane Library databases, and gray literature for the search. Experimental and observational studies, reviews, care guidelines and meta-analysis were included, conducted in pediatric patients without underlying diseases, with acute infectious diarrhea, comparing the use of lactose-free milk versus regular milk. Results: Twelve articles were selected. Nine of them showed a decrease in the duration of diarrhea in patients who received lactose-free milk with a mean difference of 18 hours (ranging from 4 to 32.6 hours). No statistically significant differences in mortality were reported between the use of one or the other milk formula. Regarding the use of one or the other formula, there were no statistically significant variations in weight. The need for hospital admission was similar between the two groups. Only one article analyzed stool frequency or volume with no significant differences (AU)

Uso de vasopresina en el postoperatorio de cirugía de Fontan: inferencias sobre morbimortalidad / Vasopressin use in postoperative Fontan surgery: implications for morbidity and mortality

Introducción: Se ha postulado que el uso de vasopresina tendría efectos beneficiosos en el postoperatorio de cirugía cardiovascular. Objetivo: Evaluar la respuesta a la vasopresina en el postoperatorio (POP) de cirugía de Fontan de nuestra población. Métodos: Estudio de casos y controles anidados en una cohorte retrospectiva. Se incluyeron pacientes con cirugía de Fontan entre 2014 y 2019. Se registraron variables demográficas, datos del cateterismo pre-Fontan, días de asistencia respiratoria mecánica (ARM), necesidad de inotrópicos, diuréticos, diálisis, dieta hipograsa, octreotide, sildenafil y nutrición parenteral total (NPT); balance de fluidos al primer y segundo día POP, necesidad de cateterismo en el POP, días de permanencia de tubo pleural, días de internación, necesidad de reinternación y mortalidad. Se compararon los grupos con y sin vasopresina utilizando la prueba de Mann- Whitney-Wilcoxon test. Se consideró significativa una p < 0.05. Resultados: Del total analizado, 35 pacientes recibieron vasopresina. En el grupo control fueron 58 pacientes con características similares de gravedad sin vasopresina. No se encontraron diferencias en la evolución postoperatoria entre ambos grupos. El grupo con vasopresina recibió en mayor proporción dieta hipograsa. Conclusiones: En nuestra serie el uso de vasopresina no marcó diferencias significativas en términos de morbimortalidad con relación al grupo control (AU)

Introduction: The use of vasopressin has been suggested to have beneficial effects in the postoperative period after cardiovascular surgery. Objective: To evaluate the response to vasopressin in the postoperative period (POP) of Fontan surgery in our population. Methods: Nested case-control study in a retrospective cohort. Patients who underwent Fontan surgery between 2014 and 2019 were included. Demographic variables, pre-Fontan catheterization data, days of mechanical ventilation (MRA), need for inotropics, diuretics, dialysis, low-fat diet, octreotide, sildenafil and total parenteral nutrition (TPN); fluid balance at first and second day POP, need for catheterization at POP, duration of chest tube drainage, days of hospitalization, need for readmission, and mortality were recorded. Groups with and without vasopressin were compared using the Mann-Whitney- Wilcoxon test. A p < 0.05 was considered significant. Results: Of all patients analyzed, 35 received vasopressin. The control group consisted of 58 patients with similar severity characteristics who did not receive vasopressin. No differences were found in the postoperative outcome between the two groups. The vasopressin group received a higher proportion of low-fat diet. Conclusions: In our series the use of vasopressin did not show significant differences in terms of morbidity and mortality compared to the control group (AU)

Alimentación basada en plantas: la nueva tendencia nutricional / Plant-based diets: the new nutritional trend

En la actualidad cada vez más familias optan por seguir una alimentación basada en plantas (ABP). Es fundamental que pediatras y agentes de salud conozcan estos tipos de patrones alimentarios para asesorar adecuadamente a sus pacientes y derivarlos oportunamente a especialistas capacitados con el objetivo de garantizar un adecuado crecimiento y desarrollo principalmente en la edad pediátrica, evitando posibles consecuencias negativas sobre la salud. La mayoría de las sociedades científicas del mundo considera a las dietas vegetarianas apropiadas para todas las etapas de la vida si están correctamente planificadas, suplementadas y con un seguimiento adecuado por especialistas capacitados. Con respecto a las dietas veganas existen controversias por parte de las distintas sociedades con respecto a si son adecuadas o no en pediatría. Recientemente se han revisado las descripciones respecto a las tipificaciones de una ABP y se ha propuesto una definición estándar de estos tipos de dieta. Los riesgos más significativos asociados a la mala planificación de estas dietas son las deficiencias de calcio, vitamina D y vitamina B12, aunque también se debe tener en cuenta el estado del zinc, selenio, yodo y los ácidos grasos Omega 3. Es importante la planificación diaria de un plato nutricionalmente completo y es incuestionable que quienes siguen estos patrones alimentarios reciban suplementos con vitamina B12 adecuados para cada etapa de la vida. Se requieren más estudios en pediatría para evaluar los efectos de las distintas ABP sobre la ingesta de nutrientes, el estado nutricional, el crecimiento, desarrollo y la prevención de enfermedades no transmisibles (AU)

Currently, an increasing number of families are choosing to follow a plant-based diet (PBD). It is essential that pediatricians and healthcare agents know these types of dietary patterns in order to properly advise their patients and refer them to trained specialists to ensure adequate growth and development, especially in the pediatric age, avoiding possible negative health consequences. Most of the world's scientific societies consider vegetarian diets appropriate for all stages of life if they are adequately planned, supplemented and monitored by trained specialists. However, there is controversy among different societies regarding the appropriateness of vegan diets for children. Recently, there has been a review of descriptions concerning the characteristics of a plant-based diet, leading to a proposed standard definition for these types of diets. The most significant risks associated with poorly planned diets are calcium, vitamin D, and vitamin B12 deficiencies, although zinc, selenium, iodine and omega-3 fatty acid status should also be considered. The daily planning of a nutritionally complete meal is important and it is imperative that those who follow these dietary patterns receive vitamin B12 supplementation appropriate for each stage of life. Further studies in children are needed to evaluate the effects of different PBDs on nutrient intake, nutritional status, growth, development, and prevention of noncommunicable diseases (AU)

Estudio de la vía aérea superior frente a apneas obstructivas del sueño persistentes en pediatría / An approach to the upper airway evaluation in pediatric persistent obstructive sleep apnea

El síndrome de apneas obstructivas del sueño (SAOS) en pediatría constituye un trastorno asociado a múltiples consecuencias en el espectro cognitivo y comportamental. El principal factor de riesgo asociado es la hipertrofia amigdalina y las vegetaciones adenoideas. La adenoamigdalectomía es el tratamiento de primera línea. La incidencia del SAOS persistente varía entre un 15 % y un 75 % según las comorbilidades. Este se presenta como un desafío a la hora de tratarlo; requiere un abordaje integral para su diagnóstico y tratamiento adecuado. El objetivo de esta revisión bibliográfica es proponer un abordaje diagnóstico y terapéutico para el SAOS persistente.

In pediatrics, obstructive sleep apnea syndrome (OSAS) is a disorder associated with multiple consequences at the cognitive and behavioral level. The main associated risk factor is the presence of tonsillar hypertrophy and adenoids. An adenotonsillectomy is the first-line treatment. The incidence of persistent OSAS varies from 15% to 75%, depending on comorbidities. This is a challenge in terms of management; it requires a comprehensive approach for an adequate diagnosis and treatment. The objective of this bibliographic review is to propose a diagnostic and therapeutic approach for persistent OSAS.

Trasplante de médula ósea haploidéntico en un paciente pediátrico con síndrome de Wiskott-Aldrich. A propósito de un caso / Haploidentical bone marrow transplantation in a pediatric patient with Wiskott-Aldrich syndrome. A case report

El síndrome de Wiskott-Aldrich es un error innato de la inmunidad de herencia ligada al cromosoma X, producido por variantes en el gen que codifica la proteína del síndrome de Wiskott-Aldrich (WASp). Reportamos el caso clínico de un paciente de 18 meses con diagnóstico de Wiskott-Aldrich que no presentaba donante antígeno leucocitario humano (HLA) idéntico y recibió un trasplante de células progenitoras hematopoyéticas (TCPH) con donante familiar haploidéntico. La profilaxis para enfermedad de injerto contra huésped incluyó ciclofosfamida (PT-Cy). El quimerismo del día +30 fue 100 % del donante y la evaluación postrasplante de la expresión de la proteína WAS fue normal. Actualmente, a 32 meses del trasplante, presenta reconstitución hematológica e inmunológica y quimerismo completo sin evidencia de enfermedad injerto contra huésped. El TCPH haploidéntico con PT-Cy se mostró factible y seguro en este caso de síndrome de WiskottAldrich en el que no se disponía de un donante HLA idéntico.

Wiskott-Aldrich syndrome (WAS) is an X-linked genetic disorder caused by mutations in the gene that encodes the Wiskott-Aldrich syndrome protein (WASp). Here, we report the clinical case of an 18-month-old boy diagnosed with Wiskott-Aldrich syndrome, who did not have an HLA-matched related or unrelated donor and was treated successfully with a hematopoietic stem cell transplant (HSCT) from a haploidentical family donor. Graft-versus-host disease (GvHD) prophylaxis included post-transplant cyclophosphamide (PT-Cy). At day +30, the peripheral blood-nucleated cell chimerism was 100% and the WAS protein had a normal expression. Currently, at month 32 post-transplant, the patient has hematological and immune reconstitution and complete donor chimerism without evidence of GvHD. HSCT with PT-Cy was a feasible and safe option for this patient with WAS, in which an HLA matched donor was not available.

Mucositis oral como efecto adverso al uso del metotrexato en el tratamiento de la artritis reumatoide: una revisión sistematizada de casos / Oral mucositis as an adverse effect of the use of methotrexate in the treatment of rheumatoid arthritis: a systematized review of cases

Introducción: el metotrexato se usa ampliamente para el tratamiento de una variedad de enfermedades neoplásicas y autoinmunes. Sin embargo, como todo fármaco, su eficacia viene marcada por cierto grado de toxicidad debido a la farmacocinética del medicamento. El metotrexato se creó como un fármaco anticancerígeno; sin embargo, se ha convertido en el tratamiento de elección contra la artritis reumatoide. Principalmente, el metotrexato causa inflamación de las mucosas epiteliales. La mayoría de los efectos secundarios del metotrexato se pueden detectar de forma temprana y son reversibles. La mucositis del tracto alimentario es el principal efecto secundario de la quimioterapia contra el cáncer. Se le conoce colectivamente como lesión de la mucosa inducida por quimioterapia, afecta todo el canal alimentario desde la boca hasta el ano, ocasionando la mucositis oral y la mucositis intestinal. Material y métodos: se buscaron casos clínicos en los que se reporte mucositis causada por metotrexato en tratamiento de artritis reumatoide. Se empleó un diagrama de flujo, PRISMA modificado para la búsqueda de artículos. Finalmente, se cotejó que los casos clínicos cumplieran con los fundamentos de la CARE guide, para manejar una correcta estructura y bajo riesgo a sesgo. Conclusiones: una correcta anamnesis y exploración clínica oral es lo más importante de la medicina oral. Es relevante indagar sobre las enfermedades que presentan los pacientes, así como la historia de medicamentos que se administren, especialmente en pacientes mayores, con mayores padecimientos de enfermedades sistémicas (AU)

Introduction: methotrexate is widely used for the treatment of a variety of neoplastic and autoimmune diseases. However, like all drugs its efficacy is marked by a certain degree of toxicity due to the pharmacokinetics of the drug. Methotrexate was developed as an anticancer drug, however, it has become the treatment of choice for rheumatoid arthritis. Methotrexate primarily causes inflammation of the epithelial mucous membranes. Most of the side effects of methotrexate can be detected early and are reversible. Mucositis of the alimentary tract is the main side effect of cancer chemotherapy. It is collectively known as chemotherapy-induced mucosal injury, affecting the entire alimentary canal from the mouth to the anus, where oral mucositis and intestinal mucositis are both common. Material and methods: we searched for clinical cases reporting mucositis caused by methotrexate in the treatment of rheumatoid arthritis, using a modified PRISMA flowchart to search for articles. Finally, the clinical cases were checked for compliance with the fundamentals of the CARE guide, in order to manage a correct approach to oral medicine. It is important to inquire about the diseases the patients present, as well as the history of medications administered, especially in older patients, with more systemic disease conditions, structure, and low risk of bias. Conclusion: a correct anamnesis and oral clinical examination is the most important aspect of oral medicine. It is important to inquire about the diseases that the patients present, as well as the history of medications that are administered, especially in older patients with major systemic diseases (AU)

Alterações oculares decorrentes de picada de abelha na córnea / Ocular changes due to corneal bee sting

RESUMO O propósito deste estudo foi reportar as alterações oculares observadas após picada de abelha com ferrão retido na córnea. Destacamos o tratamento e o desfecho de uma lesão de córnea incomum e sua patogênese. Trata-se de relato de caso e revisão da literatura de lesões oculares por picada de abelha. Paciente do sexo feminino, 63 anos, procurou atendimento oftalmológico de urgência devido à picada de abelha na córnea do olho direito há 6 dias. Queixava-se de embaçamento visual, dor e hiperemia ocular. Apresentou acuidade visual de vultos no olho afetado. Ao exame, notaram-se hiperemia moderada de conjuntiva bulbar, edema corneano com dobras de Descemet e presença do ferrão alojado na região temporal, no estroma profundo da córnea. A paciente foi internada para ser abordada no centro cirúrgico sob anestesia geral. Durante a cirurgia, o ferrão teve que ser retirado via câmara anterior, mediante a realização de uma paracentese e uma lavagem da câmara anterior, com dupla via e solução salina balanceada. Ainda não existe na literatura um tratamento padrão na abordagem de pacientes com lesões oculares por picada de abelha, sendo importantes a identificação e o reconhecimento precoce de possíveis complicações que ameacem a visão.

ABSTRACT The purpose of this study was to report the ocular changes observed after a bee sting with a stinger retained in the cornea. We show the treatment and outcome of an unusual corneal injury and its pathogenesis. This is a case report and literature review of ocular injuries caused by bee stings. A 63-year-old female patient sought emergency ophthalmic care because of a bee sting on the cornea of her right eye six days before. She complained of blurred vision, pain, and ocular hyperemia. She had glare sensitivity on visual acuity in the affected eye. Examination revealed moderate hyperemia of the bulbar conjunctiva, corneal edema with Descemet's folds and a stinger lodged in the temporal region, in the deep stroma of the cornea. The patient was admitted to the operating room under general anesthesia. During surgery, the stinger had to be removed via the anterior chamber, by performing a paracentesis and washing the anterior chamber with a double flushing and balanced saline solution. There is still no standard treatment in the literature for patients with eye injuries caused by bee stings, and early identification and recognition of possible sight-threatening complications is important.

Activation of M1 muscarinic acetylcholine receptors by proline-rich oligopeptide 7a (

Background: The bioactive peptides derived from snake venoms of the Viperidae family species have been promising as therapeutic candidates for neuroprotection due to their ability to prevent neuronal cell loss, injury, and death. Therefore, this study aimed to evaluate the cytoprotective effects of a synthetic proline-rich oligopeptide 7a (PRO-7a; <EDGPIPP) from Bothrops jararaca snake, on oxidative stress-induced toxicity in neuronal PC12 cells and astrocyte-like C6 cells. Methods: Both cells were pre-treated for four hours with different concentrations of PRO-7a, submitted to H2O2-induced damage for 20 h, and then the oxidative stress markers were analyzed. Also, two independent neuroprotective mechanisms were investigated: a) L-arginine metabolite generation via argininosuccinate synthetase (AsS) activity regulation to produce agmatine or polyamines with neuroprotective properties; b) M1 mAChR receptor subtype activation pathway to reduce oxidative stress and neuron injury. Results: PRO-7a was not cytoprotective in C6 cells, but potentiated the H2O2-induced damage to cell integrity at a concentration lower than 0.38 μM. However, PRO-7a at 1.56 µM, on the other hand, modified H2O2-induced toxicity in PC12 cells by restoring cell integrity, mitochondrial metabolism, ROS generation, and arginase indirect activity. The α-Methyl-DL-aspartic acid (MDLA) and L-NΩ-Nitroarginine methyl ester (L-Name), specific inhibitors of AsS and nitric oxide synthase (NOS), which catalyzes the synthesis of polyamines and NO from L-arginine, did not suppress PRO-7a-mediated cytoprotection against oxidative stress. It suggested that its mechanism is independent of the production of L-arginine metabolites with neuroprotective properties by increased AsS activity. On the other hand, the neuroprotective effect of PRO-7a was blocked in the presence of dicyclomine hydrochloride (DCH), an M1 mAChR antagonist. Conclusions: For the first time, this work provides evidence that PRO-7a-induced neuroprotection seems to be mediated through M1 mAChR activation in PC12 cells, which reduces oxidative stress independently of AsS activity and L-arginine bioavailability.(AU)

Effect of Water and Chlorhexidine with Different Pressures of Oral Irrigation Device on the Surface Roughness and Topography of Giomer

Abstract Objective: To evaluate the effect of different pressures of an oral irrigation device (OID) and the irrigation solution type on the surface roughness of the giomer restorative material. Material and Methods: In this in vitro study, disk-shaped giomer samples were fabricated and assigned to 5 groups (n=23): Group 1, storage in distilled water (control); Group 2, OID #7 pressure/ water; Group 3, OID #10 pressure/ water; Group 4, OID #7 pressure/ 0.05% CHX; Group 5, OID #10 pressure/ 0.05% CHX. The samples' treatment simulated a one-year application of OID. Surface roughness (Ra) and topography of the giomer were evaluated using profilometry and scanning electron microscopy. The data were analyzed with Paired t-test, Tukey, and ANOVA tests (α=0.05). Results: The Ra of the samples increased significantly after treatment with OID (p<0.001). The roughness increase in groups with a pressure of 10 was higher than those with a pressure of 7 (p<0.001). The effect of pressure on surface changes was significant (p<0.001). However, the solution type and the cumulative effect of these two factors were insignificant (p=0.08 and p=0.43, respectively). Conclusion: Oral irrigation device with both solutions significantly increased the surface roughness and topographic changes of the giomer. The severity of these changes was related to the device's pressure.

Desensitizing Agent Previously Applied During In-Office Bleaching: A Double-Blind Randomized Clinical Trial

Abstract Objective: To compare the clinical effect of two desensitizing agents used before the application of a bleaching gel based on 35% hydrogen peroxide (HP). Material and Methods: 30 patients were selected, and two desensitizing agents with different mechanisms of action were applied: Fluorine Neutral 2% (FN), which acts by blocking dentinal canaliculi while Potassium Nitrate 5% with 2% Sodium Fluoride (PN/SF) that acts in nerve transmission and blockade. Desensitizers were used before the application of 35% HP. For whitening, three clinical sessions were performed, with an interval of seven days, with three applications of the bleaching gel for 15 minutes, totaling 45 minutes/session. Tooth sensitivity (TS) was assessed with the numerical analog scale, and a spectrophotometer was used to obtain the color variation (ΔE). ΔE were submitted to ANOVA and Tukey test (p<0.05), and TS data were submitted to a two-way ANOVA analysis. Results: For sensitivity experience, the Tukey test indicated differences between PN/SF and the placebo I, but there was no statistically significant difference between FN and the placebo II. The TS was lower when the desensitizing gel was used during the bleaching procedure compared to after treatment, regardless of the desensitizing agents. Conclusion: PN/SF before in-office tooth bleaching can reduce TS intensity, and the use of desensitizing gel before bleaching did not affect the bleaching efficacy.

Headache as the most prevalent post-vaccination adverse event after Covid-19 vaccination / Dor de cabeça como evento adverso pós-vacinação mais prevalente após a vacinação contra Covid-19

BACKGROUND: In 2020, the first vaccines were approved, according to the WHO. However, speculations arose regarding their efficacy and post-vaccination adverse events (AEFV). OBJECTIVE: To evaluate the prevalence of headache as AEFI from the SARSCoV-2 vaccine in Piauí, Brazil. METHODS: This is a quantitative, observational, cross-sectional, and prevalence study. Data were provided by the Post-Vaccination Adverse Event Information System (SI-AEFV), from reported cases from January to September 2021. Data were analyzed, and the research was approved by the UFPI Research Ethics Committee. RESULTS: A total of 2,008 cases were analyzed. Headache was reported in 752 cases (27.99%) as an AEFV after vaccination against SARS-CoV-2. In most cases, patients were from Teresina (67.62%), of brown race/ethnicity (52.67%), female (79.00%), and the majority were not healthcare professionals (54.27%). The most common age of patients, with the original data, was 33 years. After data correction, the most common age was 28 years. The majority of these cases were not severe (96.44%), and the majority of cases were associated with the first dose of the Covid-19-Covishield-Oxford/AstraZeneca vaccine (43.18%).CONCLUSION: Thus, it is concluded from the partial analysis of the results that headache is the most common adverse event after vaccination against SARS-CoV-2. The profile of patients with the most notifications was brown women aged 30 to 40 years who received the first dose of the Covid-19-Covishield-Oxford/AstraZeneca vaccine. Regarding the severity of events, the vast majority were considered non-severe, and no deaths were mentioned, demonstrating the safety of immunobiologicals.

Protocolo para la medición de espacios vacíos dentro de la obturación endodóntica con microtomografía / A protocol for the measurement of voids within the endodontic filling with microtomography

La microtomografía es un estudio que utiliza la ra-diación X para obtener imágenes de tamaños de mi-lésimas de milímetros y de alta resolución. Las imá-genes 2D son procesadas por diferentes softwares para lograr obtener volúmenes capaces de ser ana-lizados tridimensionalmente. La microtomografía es el estudio de elección a la hora de evaluar caracte-rísticas muy pequeñas con gran precisión. La obtu-ración endodóntica buscar lograr un sellado que no tenga espacios vacíos dentro de la masa de obtura-ción. Esto es importante debido a que los poros pue-den permitir, si están en contacto con la pared den-tinaria, la entrada de microorganismos al conducto radicular. El objetivo de este trabajo fue describir el procedimiento para el análisis y visualización de los espacios vacíos dentro de la obturación endodónti-ca, utilizando la microtomografía de rayos x, y esta-blecer un protocolo para ser utilizado por cualquier investigador(AU)

Microtomography is a study that uses X-radiation to obtain high-resolution images of sizes of thousandths of millimeters. The 2D images are processed by different software to obtain volumes capable of being analyzed three-dimensionally. Microtomography is the study of choice when evaluating very small features with great precision. Endodontic filling seeks to achieve a seal that does not have voids within the filling obturation. This is important because the voids can allow, if they are in contact with the dentin wall, the entry of microorganisms into the root canal. The objective of this work was to describe the procedure for the analysis and visualization of voids within the endodontic filling using microtomography and to establish the protocol to be used by any researcher (AU)
