Stevens-Johnson Syndrome, Toxic Epidermal Necrolysis: Macules, Papules, and Bullae.

OBJECTIVE: The objective of this discussion paper is to illuminate the importance of early identification and treatment of Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN). SJS/TEN may occur as quickly as 4 days, more commonly 4 to 8 weeks after starting a new medication and early identification is essential. METHODS: A review of literature revealed there is a lack of diagnostic awareness related to the clinical presentation and diverse populations at risk for this devastating syndrome. RESULTS: A Boolean search was conducted, and six quantitative and qualitative research articles were discovered that indicate a knowledge disparity between "rash" versus SJS/TEN. Research indicates evidence-based best clinical practices for nurses and health care practitioners for assessment of risks, clinical presentation, and treatment. CONCLUSIONS: Prompt diagnosis and discontinuation of the suspected medication will reduce potential life-threatening sequelae.

Identifying adaptations for a mindfulness program for Spanish-speaking mothers of children with chronic conditions or disabilities.

Mothers of children with chronic conditions or disabilities have benefited from mindfulness programs, yet culturally relevant mindfulness programs for Spanish-speaking mothers are lacking. We aimed to explore how this population experienced a peer-led mindfulness program to inform adaptations. Sixteen mothers attended a 6-week program and completed semi-structured interviews. Using a realist evaluation framework, we explored relationships between participants' context, the program's mechanisms and outcomes. Our thematic analysis found that four contextual factors-faith, self-concept as a woman and mother, trauma, and level of social support-influenced how participants experienced the mechanisms. Mechanisms included having positive experiences when trying practices, engaging in self-reflection, and sharing life experiences and learning in community. The mechanisms led to four outcomes: emotion regulation, savoring daily life experiences, empowerment to practice self-care and common humanity. Faith was an important enabling factor because participants had positive experiences when integrating their faith with program content. Future research should examine adaptations that invite participants to explore this synergy. Self-reflection should also be emphasized because it increased motivation to use practices and helped address barriers to engagement. Because the four contextual factors apply to many Spanish-speaking immigrants, these adaptations could enhance mindfulness programs for this population more broadly.

La ecuación de ajuste fue: 10,34249 x (1,00007 ^ Alt). Conclusiones. Los niños residentes en Arequipa y Puno mostraron mayores proporciones de DH y menores reservas de hierro; además el aumento de la hemoglobina por altitud fue exponencial evidenciando la necesidad de ajustar la hemoglobina en altura.

ABSTRACT Objective. To describe the iron status profile and to propose hemoglobin adjustment factors for altitude for children aged 6 to 8 months in Lima, Arequipa, Cusco and Puno. Materials and methods. Cross-sectional study in children aged 6 to 8 months from four cities. We measured hemoglobin and other iron biomarkers, C-reactive protein (CRP), among others. To estimate the adjustment equation, we applied an exponential regression. We excluded children with iron deficiency (ID) and/or inflammation. Results. The proportions of ID were higher in Puno and Arequipa, while inflammation did not exceed 19% in any of the cities. Hemoglobin showed an exponential increase at higher altitude. The adjustment equation was: 10.34249 x (1.00007 ^ Alt). Conclusions. Children residing in Arequipa and Puno showed higher rates of ID and lower iron reserves; furthermore, the increase in hemoglobin by altitude was exponential, showing the need to adjust hemoglobin at altitude.

Effect of Immunosuppressive Treatments on Kidney Outcomes After Gross Hematuria-Related Acute Kidney Injury in Older Patients With IgA Nephropathy.

Introduction: Macroscopic hematuria (MH) bouts, frequently accompanied by acute kidney injury (AKI-MH) are one of the most common presentations of IgA nephropathy (IgAN) in the elderly. Immunosuppressive therapies are used in clinical practice; however, no studies have analyzed their efficacy on kidney outcomes. Methods: This is a retrospective, multicenter study of a cohort of patients aged ≥50 years with biopsy-proven IgAN presenting with AKI-MH. Outcomes were complete, partial, or no recovery of kidney function at 1 year after AKI-MH, and kidney survival at 1, 2, and 5 years. Propensity score matching (PSM) analysis was applied to balance baseline differences between patients treated with immunosuppression and those not treated with immunosuppression. Results: The study group consisted of 91 patients with a mean age of 65 ± 15 years, with a mean follow-up of 59 ± 36 months. Intratubular red blood cell (RBC) casts and acute tubular necrosis were found in all kidney biopsies. The frequency of endocapillary hypercellularity and crescents were low. Immunosuppressive therapies (corticosteroids alone or combined with mycophenolate mofetil or cyclophosphamide) were prescribed in 52 (57%) patients, whereas 39 (43%) received conservative treatment. There were no significant differences in the proportion of patients with complete, partial, or no recovery of kidney function at 1 year between patients treated with immunosuppression and those not treated with immunosuppression (29% vs. 36%, 30.8% vs. 20.5% and 40.4 % vs. 43.6%, respectively). Kidney survival at 1, 3, and 5 years was similar among treated and untreated patients (85% vs. 81%, 77% vs. 76% and 72% vs. 66%, respectively). Despite the PSM analysis, no significant differences were observed in kidney survival between the two groups. Fourteen patients (27%) treated with immunosuppression had serious adverse events. Conclusions: Immunosuppressive treatments do not modify the unfavorable prognosis of patients with IgAN who are aged ≥50 years presenting with AKI-MH, and are frequently associated with severe complications.

Urgent endoscopy versus early endoscopy: Does urgent endoscopy play a role in acute non-variceal upper gastrointestinal bleeding? / Endoscopia urgente frente a endoscopia precoz: ¿tiene algún papel la endoscopia urgente en la hemorragia digestiva alta aguda no varicosa?

INTRODUCTION: The main clinical practice guidelines recommend endoscopy within 24hours after admission to the Emergency Department in patients with non-variceal upper gastrointestinal bleeding. However, it is a wide time frame and the role of urgent endoscopy (<6hours) is controversial. MATERIAL AND METHODS: Prospective observational study carried out at La Paz University Hospital, where all patients were selected, from January 1, 2015 to April 30, 2020, who attended the Emergency Room and underwent endoscopy for suspected upper gastrointestinal bleeding. Two groups of patients were established: urgent endoscopy (<6hours) and early endoscopy (6-24hours). The primary endpoint of the study was 30-day mortality. RESULTS: A total of 1096 were included, of whom 682 underwent urgent endoscopy. Mortality at 30days was 6% (5% vs 7.7%, P=.064) and rebleeding was 9.6%. There were no statistically significant differences in mortality, rebleeding, need for endoscopic treatment, surgery and/or embolization, but there were differences in the necessity for transfusion(57.5% vs 68.4%, P<.001) and the number of concentrates of transfused red blood cells (2.85±4.01 vs 3.51±4.09, P=.008). CONCLUSION: Urgent endoscopy, in patients with acute upper gastrointestinal bleeding, as well as the high-risk subgroup (GBS ≥12), was not associated with lower 30-day mortality than early endoscopy. However, urgent endoscopy in patients with high-risk endoscopic lesions (ForrestI-IIB), was a significant predictor of lower mortality. Therefore, more studies are required for the correct identification of patients who benefit from this medical approach (urgent endoscopy).

Effects of the lockdown due to the COVID-19 pandemic on alcohol consumption in patients under treatment in an alcohol relapse prevention programme. / Efectos del confinamiento en el hogar debido a la pandemia por COVID-19 en el consumo en pacientes en tratamiento en un programa de deshabituación de alcohol.

During the COVID-19 pandemic, several exceptional measures were put in place in order to avoid virus propagation, such as lockdown and the discontinuation of usual health care assistance services. It was considered that these changes might be associated with an increase in alcohol consumption and a higher risk of relapse for patients under treatment. The aim of this study was to assess changes in alcohol consumption during the lockdown period (between March and May, 2020) in patients following treatment under the Alcohol Use Disorders Programme at the "Hospital 12 de Octubre" in Madrid. A total of 311 patients were assessed through interviews carried out by telephone in accordance with usual clinical practice during that period. 76% of the total number of patients did not experience changes in their alcohol consumption, 9.2% stopped drinking and some experienced severe withdrawal syndrome, while 7.5% relapsed. The risk factors found for worsening the prognosis of the patients were: being female, drinking alcohol alone or at home, binge drinking, concomitant substance misuse and failure to attend therapy groups or self-help groups online during the lockdown. 31.6% of the sample described psychopathological symptoms due to the lockdown, especially those who already had psychiatric comorbidities. For this reason, we can conclude that during the lockdown as a result of the pandemic, most of our alcohol dependent patients did not modify their drinking patterns, but specific factors enabled us to identify a more vulnerable subgroup.

Durante la pandemia producida por la infección por el Covid-19 se produjeron una serie de cambios sociosanitarios excepcionales para evitar su propagación como el confinamiento en el hogar y la supresión de los servicios asistenciales sanitarios habituales. Se consideró que estos cambios podrían implicar un incremento en el consumo de alcohol y un mayor riesgo de recaídas para los pacientes en tratamiento. El objetivo de este estudio fue valorar los cambios en el consumo durante el período de confinamiento (marzo a mayo de 2020) en los pacientes en tratamiento en el programa de alcohol del Hospital Doce de Octubre de Madrid. Fueron valorados 311 pacientes mediante entrevista telefónica dentro de la práctica clínica habitual durante ese período. Un 76 % de los pacientes no presentaron cambios en su situación de consumo, un 9,2% de estos cesaron en el consumo, algunos de ellos con cuadros de abstinencia graves, y un 7,5% recayeron. El sexo femenino, el consumo en solitario o en el hogar, en atracón, o el de otras drogas de forma concomitante y el no estar en terapia grupal o no asistir a grupos de las asociaciones de ayuda mutua por videoconferencia durante el confinamiento fueron factores predictores de mal pronóstico. Un 31,6% presentó alteraciones psicopatológicas debidas al confinamiento, sobre todo, aquellos pacientes con comorbilidad psiquiátrica. Por lo tanto, en situaciones similares a esta, la mayoría de los pacientes en tratamiento no modifican el patrón de consumo, pero, ciertas características identifican un subgrupo de sujetos más vulnerables.

Mutational Landscape of CEBPA in Mexican Pediatric Acute Myeloid Leukemia Patients: Prognostic Implications.

Background: In Mexico, the incidence of acute myeloid leukemia (AML) has increased in the last few years. Mortality is higher than in developed countries, even though the same chemotherapy protocols are used. CCAAT Enhancer Binding Protein Alpha (CEBPA) mutations are recurrent in AML, influence prognosis, and help to define treatment strategies. CEBPA mutational profiles and their clinical implications have not been evaluated in Mexican pediatric AML patients. Aim of the Study: To identify the mutational landscape of the CEBPA gene in pediatric patients with de novo AML and assess its influence on clinical features and overall survival (OS). Materials and Methods: DNA was extracted from bone marrow aspirates at diagnosis. Targeted massive parallel sequencing of CEBPA was performed in 80 patients. Results: CEBPA was mutated in 12.5% (10/80) of patients. Frameshifts at the N-terminal region were the most common mutations 57.14% (8/14). CEBPA biallelic (CEBPA BI) mutations were identified in five patients. M2 subtype was the most common in CEBPA positive patients (CEBPA POS) (p = 0.009); 50% of the CEBPA POS patients had a WBC count > 100,000 at diagnosis (p = 0.004). OS > 1 year was significantly better in CEBPA negative (CEBPA NEG) patients (p = 0.0001). CEBPA POS patients (either bi- or monoallelic) had a significantly lower OS (p = 0.002). Concurrent mutations in FLT3, CSF3R, and WT1 genes were found in CEBPA POS individuals. Their contribution to poor OS cannot be ruled out. Conclusion: CEBPA mutational profiles in Mexican pediatric AML patients and their clinical implications were evaluated for the first time. The frequency of CEBPA POS was in the range reported for pediatric AML (4.5-15%). CEBPA mutations showed a negative impact on OS as opposed to the results of other studies.

The influence of patient´s perspective in therapeutic adherence in rheumatoid arthritis : a case study from Spain.

OBJECTIVES: The main objective is to study the contribution of illness and medication beliefs to treatment adherence in patients with rheumatoid arthritis. METHODS: the design was a cross-sectional study. The compliance Questionnaire for Rheumatology (CQR) was used to measure therapeutic adherence. The beliefs about medicines questionnaire (BMQ) and the brief illness perception questionnaire (IPQ-b) were used to assess patient's beliefs about medicines and about the disease. Other factors studied were treatment satisfaction, patient´s demographic and clinical characteristics. RESULTS: 144 patients were included in the study, 113 (78.4%) patients showed good treatment adherence. Patients with poor adherence presented higher scores in the BMQ harm domain (13±5 vs. 11±3, p= 0.013). Meanwhile, patients with good adherence presented higher scores in the necessity BMQ domain (21±3 vs. 20±3, p= 0.015), increased feeling of treatment control (8.8± 1.5 vs. 7.7± 2.1,p= 0.008), higher emotional response (6.2±3.1 vs. 4.8±3.4,p= 0.042) and a higher level of treatment satisfaction (77.2±12.4 vs. 69.9±12.5,p=0.004). In a multivariate analysis for each unit of increase in the score of BMQ´s harm domain, adherence was reduced by 20% (CI 95% 0.08-0.3, p= 0.001); for each unit of increase in treatment control item of the IPQ-b, adherence increased 1.4 times (CI 95% 1.1-1.8,p= 0.006); and for each unit of increase in the emotional response item of the IPQ-b, adherence increased 1.3 times (CI 95% 1.1-1.5,p= 0.002). CONCLUSION: in our cohort of RA patients, good adherence is associated with stronger treatment necessity perception, stronger feeling of treatment control, higher emotional response and higher level of treatment satisfaction; on the other side, patients with poor adherence had stronger beliefs of medicines as harmful substances.

Consensus in acute myeloid leukemia in Mexico.

Acute myeloid leukemia (AML) comprises a heterogeneous group of hematopoietic cell neoplasms of myeloid lineage that arise from the clonal expansion of their precursors in the bone marrow, interfering with cell differentiation, leading to a syndrome of bone marrow failure. AML is a consequence of genetic and epigenetic changes (point mutations, gene rearrangements, deletions, amplifications, and arrangements in epigenetic changes that influence gene expression) in hematopoietic precursor cells, which create a clone of abnormal cells that are capable of proliferating but cannot differentiate into mature hematopoietic cells or undergo programmed cell death. The diagnosis requires more than 20% myeloid blasts in the bone marrow and certain cytogenic abnormalities. Treatment will depend on age, comorbidities, and cytogenetic risk among the most frequent.

La leucemia mieloide aguda (LMA) comprende un grupo heterogéneo de neoplasias de células hematopoyéticas de linaje mieloide que surgen de la expansión clonal de sus precursores en la médula ósea, interfiriendo con la diferenciación celular, lo que conlleva a un síndrome de falla medular. La LMA es una consecuencia de cambios genéticos y epigenéticos (mutaciones puntuales, rearreglos de genes, deleciones, amplificaciones y arreglos en cambios epigenéticos que influyen en la expression del gen) en las células hematopoyéticas precursoras, la cual crea una clona de células anormales que son capaces de proliferar, pero no se pueden diferenciar en células hematopoyéticas maduras ni sufrir una muerte celular programada. El diagnostic requiere más del 20% de blastos mieloides en médula ósea y ciertas anormalidades citogénicas. El tratamiento dependerá de la edad, comorbilidades, riesgo citogenético entre las más frecuentes.

Validación del cuestionario de elección de alimentos en jóvenes de Lima Metropolitana, Perú, 2017

RESUMEN En el actual contexto de transición nutricional es necesario explorar los factores que afectan la elección de alimentos en la población peruana, por ello el objetivo del estudio fue validar el instrumento Food Choice Questionnaire (FCQ) en Lima Metropolitana. Se realizó un estudio de corte transversal para validar el instrumento FCQ diseñado por Steptoe. Se desarrollaron 4 etapas: revisión del FCQ y adecuación al español, validación semántica y de contenido con expertos, validación de constructo utilizando el análisis factorial de componentes principales y análisis de fiabilidad con el Alfa de Cronbach. Los resultados de la validez semántica y de contenido permitieron obtener un instrumento modificado agregándose el factor "Entorno social". En la validación de constructo se realizó un análisis factorial y luego de 4 iteraciones se depuraron 7 ítems resultando un instrumento con 10 factores y 36 ítems, que respondían al 62,6% de la varianza; posteriormente con los resultados del análisis de fiabilidad, el cuestionario FCQ se redujo a 8 factores y 32 ítems. En conclusión, se obtuvo una versión validada del cuestionario FCQ para ser utilizado en población de 18 a 29 años de la capital del Perú. El cuestionario validado consta de 8 factores incluyéndose el "Entorno social". Son necesarios otros estudios en diferentes regiones y grupos poblacionales para recoger nuevos factores que influyen en la elección de alimentos.

ABSTRACT In the current nutrition transition context, the exploration of associated factors with food choices in the Peruvian population is necessary; therefore the study's objective was to validate the Food Choice Questionnaire (FCQ) in Metropolitan Lima. A cross-sectional design was conducted to validate the FCQ instrument designed by Steptoe. It was developed in 4 stages: FCQ's review and adaptation to Spanish, semantic and content validation with experts, construct validity using factorial analysis of principal components, and reliability analysis using Cronbach's Alpha. The results of the semantic and content validity produced a modified instrument with one "social environment" factor and 6 more items. For construct validity, a factorial analysis was performed and after 4 iterations, 7 items were removed, resulting an instrument with 10 factors and 36 items, which explained 62.6% of the variance. Finally, with the results of the reliability analysis, the FCQ questionnaire was reduced to 8 factors and 32 items. In conclusion, a validated version of the FCQ questionnaire was obtained to be used in 18 to 29 years old population of the capital city of Peru. The questionnaire validated consists of 8 factors including the "social environment". Other studies in different regions and population groups are necessary to collect new factors that influence food choices.

Alveolar rhabdomyosarcoma metastatic to the brain.

Alveolar rhabdomyosarcoma (ARMS) has a predilection for the peripheral extremities, and brain metastases are rare, with only a few cases reported after the initial diagnosis. We present a 22-year-old male patient with a right orbital-ethmoidal ARMS who presented with a recurrence to the brain 1 year after the initial diagnosis. He was referred to our institution due to acute neurological deterioration. A brain MRI was performed, showing an enhancing bilateral parafalcine lesion centred about the bilateral cingulate gyri with extension into the corpus callosum. The patient was taken to the operating room for a stereotactic biopsy under general anaesthesia, which was compatible with metastatic ARMS. Our case is exceedingly rare, considering the initial diagnosis of an orbital/ethmoidal ARMS, its subsequent metastasis to the brain and its clinical sequelae after a biopsy. Prognosis after cerebral metastatic ARMS is dismal, with most patients expiring due to central nervous system metastatic disease.

Effects of Bleaching Gels on Dental Enamel Crystallography.

PURPOSE: The aim of the present research was to analyse the effects of two bleaching agents, on the enamel crystallography by means of X-ray diffraction. MATERIAL AND METHODS: Twelve human sound posterior teeth, were collected for the present study (n = 12) and from each tooth two enamel slabs were obtained and randomly assigned to one of two different bleaching protocols. The first protocol involved an in-office bleaching agent (hydrogen peroxide 37.5%/ SDI Polaoffice+), and the second an at-home whitening product (carbamide peroxide 16%/ PHILIPS Zoom! NiteWhite). X-ray diffraction readings were made before and after applying the treatments in order to analyse the peak intensity and crystal domain size. Additionally, scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) were carried out to identify the composition correctly. Statistical analysis included repeated measures analysis of variance (p ≤ 0.05). Results: Peak intensity in spectra obtained by X-ray diffraction had a tendency to diminish, mostly in the at-home bleaching group. The analysed data approximate a decrease in the crystal domain size among the samples treated for longer periods of time. Statistical analysis depicted no statistically significant differences among the experimental groups (p ≥ 0.05). Conclusions: Crystal domain size had a tendency to decrease, mostly when the enamel was treated by bleaching gels that had to be applied by prolonged periods of time.

Prognostic value of ultrasound activity and parietal healing in patients with Crohn's disease.

INTRODUCTION: the "treat to target" strategy for the management of patients with Crohn's disease (CD) requires simple, reliable and non-invasive tools for continuous monitoring of the disease. Intestinal ultrasound has been proposed as an emerging technique that could be very useful in this field. MATERIAL AND METHODS: patients who had undergone an intestinal ultrasound in the clinical practice between February 2013 and October 2018 at our hospital were retrospectively included. The evolution of the patients during follow-up was assessed based on the presence of ultrasound activity and the therapeutic changes based on the results. RESULTS: two hundred and seventy-seven CD patients were included and the median follow-up time was 24 months (range 5-73 months). Signs of ultrasound inflammatory activity were identified in 166 patients (60 %), and of them, treatment was escalated in 116 patients (70 %) based on the results of the ultrasound. Among patients with identified ultrasound activity, in 166 patients (60 %) the evolution was less favorable than in those without activity, with a shorter time until the next outbreak. Thus, the median disease-free survival (without outbreaks) after performing the ultrasound was 18 months when ultrasound activity was identified (although in most of the patients [70 %] the treatment had been escalated) vs 47 months in patients without ultrasound activity. However, these differences were not statistically significant (p < 0.0001). Among the 111 patients without ultrasound activity, those who achieved "parietal healing" (74 patients) had a better evolution with a 12 % subsequent outbreak vs 27 % during follow-up (p = 0.05). Thus, 15 % of patients with parietal healing had an outbreak vs 34 % of those who had not normalized the ultrasound findings after three years of follow-up. CONCLUSION: intestinal ultrasound is a technique capable of detecting inflammatory activity in patients with Crohn's disease and the presence of ultrasound activity is a risk factor for a new outbreak of activity and/or clinical relapse. Likewise, the presence of "parietal or transmural healing" (PH) is associated with a better evolution of patients during follow-up. Thus, it could be a more precise objective to consider deep remission in CD, with intestinal ultrasound being a useful technique for this purpose.

Decrease of Postchemotherapy Complications With the Use of Probiotics in Children With Acute Lymphoblastic Leukemia.

INTRODUCTION: During the administration of antineoplastic drugs, acute complications because of toxicity occur, determining their hospital readmission, visits to the emergency department, use of antimicrobials, and possibilities of presenting systemic infections, impacting on their life quality. METHODS: Through a prospective cohort, 60 children with acute lymphoblastic leukemia were followed-up for 30 days after the hospital discharge because of chemotherapy administration, those patients were previously included in a single-blinded study in which 30 (group 1) received Lactobacillus rhamnosus GG probiotic during the administration of chemotherapy. The remaining 30 patients did not receive probiotics (group 2). There were evaluated gastrointestinal symptoms, such as diarrhea, dyspepsia, abdominal distension, meteorism, constipation, nausea, and vomit, development of infections, antibiotic use, number of emergency department visits, number of hospitalizations, and sepsis diagnosis. STATISTICAL ANALYSIS: To assess the impact of the use of probiotics, the difference in proportions between both study groups was evaluated. RESULTS: Gastrointestinal manifestations (nausea, vomiting, diarrhea, constipation) occurred in 30% of patients in group 1 versus 63% of group 2 (P=0.009). Nine of 30 patients (30.0%) in group 1 went to the emergency room, versus 33.3% of group 2 (P=0.7). Antimicrobials were used in 8 subjects (26.6%) in group 1 versus 6 subjects (53.3%) in group 2 (P=0.03) suspected of an infectious disease. Four (13.3%) group 1 patients were hospitalized versus 30% of group 2 (P=0.1). Two subjects (6.6%) in group 1 had sepsis versus 7 (23.3%) in group 2 (P=0.07).Conclusions:The results indicate that the use of probiotics can be a great alternative in the improvement of gastrointestinal symptoms and the adverse effects associated with chemotherapy.
