COVID-19 pandemic on coronary artery and cerebrovascular diseases in Southern Spain: interrupted time series analysis.

OBJECTIVE: Healthcare systems have been put under intense pressure by the COVID-19 pandemic, although some studies have shown a decline in hospital admissions for cardiovascular and cerebrovascular diseases during the first and second wave of the pandemic. In addition, studies analyzing gender and procedural differences are scarce. The present study aimed to determine the impact of the pandemic on hospital admissions for acute myocardial infarction (AMI) and cerebrovascular disease (CVD) in Andalusia (Spain) and analyzed differences by gender and by percutaneous coronary interventions performed. PATIENTS AND METHODS: An interrupted time series analysis of AMI and CVD hospital admissions in Andalusia (Spain) was carried out to measure the impact of the COVID-19 outbreak. AMI and CVD cases admitted daily in public hospitals of Andalusia between January 2018 and December 2020 were included. RESULTS: During the pandemic, significant reductions in AMI [-19%; 95% confidence interval (CI): (-29%, -9%), p<0.001] and CVD [-17%; 95% CI: (-26%, -9%); p<0.01] in daily hospital admissions were observed. Differences were also produced according to the diagnosis (ST-Elevation Myocardial Infarction, Non-ST-Elevation Myocardial Infarction, other AMI and stroke), with a greater reduction in females for AMI and in males for CVD. Although there were more percutaneous coronary interventions during the pandemic, no significant reductions were observed. CONCLUSIONS: A decline in AMI and CVD daily hospital admissions during the first and second wave of COVID-19 pandemic was noted. Gender differences were observed, but no clear impact was observed in percutaneous interventions.

Primary Sjögren's syndrome: Extraglandular manifestations and hydroxychloroquine therapy.

The use of hydroxychloroquine (HCQ) in Primary Sjögren's Syndrome (pSS) has been assessed in different studies over the last years, with conflicting results regarding its efficacy in sicca syndrome and extraglandular manifestations (EGM). The goal of this study was to compare the incidence rate of EGM in pSS patients with and without HCQ therapy.We performed a multicenter retrospective study, including patients with pSS (European classification criteria) with at least 1 year of follow-up. Subjects with concomitant fibromyalgia, autoimmune hepatitis, primary biliary cirrhosis, and primary sclerosing cholangitis were excluded. Demographics and pSS characteristics were recorded. The EGM were defined by EULAR-SS disease activity index (ESSDAI). Patients were divided into two groups according to their use or not of HCQ therapy. We evaluated the use of HCQ and its relationship to EGM. HCQ therapy was defined as the continuous use of the drug for at least 3 months. A descriptive analysis of demographics and pSS characteristics was performed. We compared the incidence of EGM between groups defined by HCQ therapy using chi2 test or Fisher's exact test. A total of 221 patients were included (97.3% women), mean age, 55.7 years (SD 14). Mean age at diagnosis, 48.8 years (SD 15); median disease duration, 60 months (IQR 35-84). One hundred and seventy patients (77%) received HCQ. About half of the patients had at least one EGM during the course of the disease, 20% of them developed an EGM before the onset of the sicca syndrome and 26% simultaneously with dryness symptom. Overall, EGM were less frequent in those on HCQ therapy (36.5% vs 63.5%, p < 0.001). Considering each EGM individually, the following manifestations were more frequent in the non-treated group: arthritis (p < 0.001), fatigue (p < 0.001), purpura (p = 0.01), Raynaud phenomenon (p = 0.003), and hypergammaglobulinemia (p = 0.006). Immunosuppressive treatment was indicated on 28 patients (12.7%), 13 of which were receiving also HCQ. The first reason for those treatments was the presence of arthritis in 12/28 patients (42.8%), and the drug used in all the cases was methotrexate. Only three patients required immunosuppressive therapy with cyclophosphamide, due to the presence of glomerulonephritis, vasculitis, and interstitial lung disease. None of the patients received biologic therapy. The lower incidence of EGM was observed in patients on HCQ therapy supports its efficacy in pSS. However, further large scale prospective studies are needed to confirm these findings.

Correlación de diferentes métodos de valoración de la rigidez matinal con índices de actividad y discapacidad en pacientes con artritis reumatoidea / Correlation of different methods of assessment of morning stiffness with activity and disability indexes in patients with rheumatoid arthritis

La rigidez matinal (RM) es un síntoma complejo en los pacientes con AR. Existen diferentes formas de valorar la RM. Sin embargo, la mejor manera de evaluarla es aún controversial. Objetivos: Comparar la severidad y la duración de la RM, evaluada por el médico y por cuestionarios autorreportados, con la actividad de la enfermedad y la capacidad funcional en pacientes con AR. Métodos: Estudio observacional de corte transversal. Se incluyeron pacientes con diagnóstico de AR. Se consignaron datos demográficos, características de la AR y medidas clinimétricas. Los pacientes fueron asignados aleatoriamente a uno de dos grupos: el primer grupo fue interrogado sobre la duración de la RM en minutos; el segundo grupo fue evaluado mediante un cuestionario autorreportado que cuantificaba la severidad de la RM (EVA numérica y no numérica) y la duración (en minutos y en escala de Likert). Resultados: Participaron 111 pacientes (86% mujeres). La edad media fue de 52 años y la mediana de duración de la enfermedad fue 8 años. El 51% presentaba RM. La correlación de la RM en minutos medida por el médico fue buena con HAQ-A y aceptable con DAS28 y CDAI; mientras que la severidad medida por EVA correlacionó mejor con los índices de actividad de la AR que con discapacidad. Cuando la intensidad de la RM fue evaluada por EVA se observó que un valor >5,5 cm se asoció con actividad severa de la enfermedad (Sensibilidad: 44%; Especificidad: 100%). Conclusión: La duración de la rigidez matinal, evaluada en minutos por el médico, estaría relacionada tanto con la actividad de la enfermedad como con la discapacidad. La intensidad de la rigidez matinal se asoció más fuertemente con la actividad inflamatoria en los pacientes con AR

Desempeño del RAPID3 (Routine Assessment of Patient Index Data) en pacientes con osteoartritis de rodilla, cadera o mano / RAPID3 (Routine Assessment of Patient Index Data) performance in patients with osteoarthritis of the knee, hip or hand

RAPID3 es un cuestionario autorreportado desarrollado originalmente para valorar pacientes con AR. Recientemente fue empleado en pacientes con OA de rodillas y/o caderas con buenos resultados. Objetivo: Determinar si existe correlación entre el RAPID3 y otros cuestionarios en pacientes con OA de manos (AUSCAN), cadera y/o rodilla (WOMAC) y comparar el tiempo para su realización y cálculo. Material y métodos: Estudio analítico observacional de corte transversal. Se incluyeron pacientes consecutivos ≥50 años con diagnóstico de OA de rodillas, caderas y/o manos que completaron el RAPID3; además el AUSCAN y/o WOMAC según la localización de la OA. Se midió el tiempo para completar y calcular los cuestionarios. Resultados: Se incluyeron 104 pacientes. Al comparar RAPID3 con WOMAC y AUSCAN se observó una correlación de 0,66 y 0,62 respectivamente (p<0,01). Al evaluar RAPID3 con la subescala de función del WOMAC, la correlación fue de 0,75 (p<0,01) y con WOMAC Ab de 0,68 (p<0,001). El tiempo para completar y calcular el RAPID3 fue menor que para los otros cuestionarios. Conclusión: Se observó buena correlación entre RAPID3, WOMAC y AUSCAN, requiriendo un menor tiempo para su realización y cálculo. Por lo tanto, podría ser una herramienta útil para evaluar pacientes con OA de rodilla, caderas y/o manos

[Implementation of a Plan of Patient Safety in Service of Pediatric Surgery. First results]. / Implementación de un Plan de Seguridad del Paciente en un Servicio de Cirugía Pediátrica. Primeros resultados.

OBJECTIVES: In 2014 our department starts to apply the PatientSafety Strategic in Pediatric Surgery. Our aim is to describe the results obtained. METHODS: For the measurement of adverse events (AE) we used a modification of the Global Trigger Tool of the Institute for Healthcare Improvement. Population analysed: patients undergoing surgery with hospitalization. On a monthly basis, audits of the medical records of 12 patients discharged in the prior week of the assessment were performed. The evaluation team was composed by experienced pediatric surgeon, two staff nurses, and a doctor and nurse from the Quality Department. RESULTS: 95 clinical records and a total of 406 days of hospital stay were reviewed. 31 patients (32.6%) experienced one or more AE. Total AE: 43. The AE/1000 patients/day ratio: 105.9. The most common AE were: vomiting, itching and pain. 28 EA were considerd mild and 3 moderate in severity, according to the classification of the National Coordinating Council for Medication Error Reporting and Prevention. No EA were considered serious or critical. CONCLUSIONS: The analysis of prevalence through regular assessments of medical records is an easy method to obtain information about the frequency of occurrence, exact understanding of the AE types and the implementation of corrective measures. The main limitation of this method is that it can miss some of the serious EA and miss the records and analysis of sentinel events that may occur in the period between assessments.

OBJETIVOS: Durante el año 2014 se aplica el Plan de Seguridad del Paciente en un Servicio de Cirugía Pediátrica, elaborado previamente por nuestro Servicio. Se describen los resultados. MATERIAL Y METODOS: El método empleado para la medición de eventos adversos (EAs) es una modificación del Global Trigger Tool del Institute for Health care Improvement. Población analizada: pacientes intervenidos quirúrgicamente con hospitalización. Con una periodicidad mensual, se realizaron 12 auditorias de las historias clínicas correspondientes a los pacientes dados de alta en la semana anterior al día de la evaluación. El equipo evaluador estaba compuesto por: un cirujano pediátrico experto, dos enfermeras de planta más un médico y una enfermera del Servicio de Calidad. RESULTADOS: Se revisaron 95 historias y 406 días de estancia. 31 pacientes (32,6%) sufrieron uno o más eventos adversos. Total EAs: 43. Número EAs/1.000 pacientes/día: 105,9. Los 3 EA más frecuentes fueron: vómitos, prurito y dolor. 28 EAs fueron de gravedad leve y 3 moderada, según la clasificación del National Coordinating Council for Medication Error Reporting and Prevention. Ningún EA fue grave o crítico. CONCLUSIONES: La determinación de la prevalencia mediante evaluaciones regulares de historias clínicas es un método que permite obtener información de forma fácil sobre la frecuencia de aparición, el conocimiento exacto de los tipos de EAs y la aplicación de medidas correctoras. Este método tiene como limitación principal la posible falta de recogida EAs graves así como registro y análisis de eventos centinelas que pueden ocurrir en el periodo entre evaluaciones.

Estudio piloto sobre correlación clínica, radiológica y ecográfica en pacientes con artritis reumatoidea / Pilot study on clinical, radiographic and ecographic correlation in patients with rehumatoid arthritis

El objetivo de este estudio piloto fue evaluar la correlación entre las evaluaciones clínicas, radiológica y ecográfica en pacientes con AR. Material y métodos: Estudio de corte transversal realizado en el marco de un taller de clinimetría y ecografía para médicos reumatólogos. Se incluyeron pacientes ≥ a 18 años de edad, con diagnóstico de AR. Los pacientes fueron evaluados a través de autocuestionarios validados: actividad de la enfermedad (RADAI), capacidad funcional (HAQ-A y HAQ-II) y RAPID-3; escala visual análoga (EVA) para dolor, evaluación global de la enfermedad y rigidez matinal (RM) y recuento articular (28) por dos médicos reumatólogos. Estos dos médicos también determinaron la evaluación global de la enfermedad de los pacientes (EVA). Se consignó valor de eritrosedimentación (ERS) dentro de la semana previa al examen. Se calculó el índice compuesto DAS28. Radiografías de manos y pies (en posición frente) efectuadas dentro de la semana previa al examen fueron leídas por otros dos médicos reumatólogos mediante método de Sharp modificado por van der Heijde (SvdH) y método SENS (Simplified Erosion and Narrowing Score). A todos los pacientes se les realizó ecografía articular Modo B y Doppler de poder (PD) de 12 por 5 médicos experimentados. Se determinó presencia de derrame de líquido sinovial (DS), hipertrofia sinovial (HS) y señal (PD). A la presencia de cada uno de estos hallazgos se les asignaba 1 punto y el índice ecográfico total resultaba de la suma de los puntos positivos (rango 0-36).

The aim of this pilot study was to evaluate the correlation betweenclinical, radiological and ultrasound assessments in patients withRA.Material and methods: Cross-sectional study conducted in theframework of a clinimetric and ultrasound workshop for rheumatologists.We included patients with rheumatoid arthritis (ACR1987) ≥ 18 years of age. Patients were evaluated using validatedquestionnaires: disease activity (RADAI), functional capacity (HAQ-Aand HAQ-II) and RAPID-3; visual analog scale (VAS) for pain, globalassessment of disease and morning stiffness (MS) and joint count(28) by two rheumatologists who also determined the global assessmentof the patient’s disease (VAS). Sedimentation rate (ESR)in the week before the exam was recorded. DAS28 composite indexwas calculated. Radiographs of hands and feet (front position) performedwithin one week before the examination were read by tworheumatologists using the Sharp method modified by van der Heijde(SvdH) and SENS (Simplified Erosion and Narrowing Score) method.All patients underwent joint ultrasonography B Mode and PowerDoppler (PD) of 12 joints by 5 experienced physicians. Presence ofeffusion of synovial fluid (SF), synovial hypertrophy (SH) and signal(PD) were determined. To the presence of each of these findingswere assigned 1 point and the total ultrasound index was the sumof the positive points (range 0-36).

Validation of laughter for diagnosis and evaluation of depression.

BACKGROUND: In the medical field, laughter has been studied for its beneficial effects on health and as a therapeutic method to prevent and treat major medical diseases. However, very few works, if any, have explored the predictive potential of laughter and its potential use as a diagnostic tool. METHOD: We registered laughs of depressed patients (n=30) and healthy controls (n=20), in total 934 laughs (517 from patients and 417 from controls). All patients were tested by the Hamilton Depression Rating Scale (HDRS). The processing was made in Matlab, with calculation of 8 variables per laugh plosive. General and discriminant analysis distinguished patients, controls, gender, and the association between laughter and HDRS test. RESULTS: Depressed patients and healthy controls differed significantly on the type of laughter, with 88% efficacy. According to the Hamilton scale, 85.47% of the samples were correctly classified in males, and 66.17% in women, suggesting a tight relationship between laughter and the depressed condition. LIMITATIONS: (i) The compilation of humorous videos created to evoke laughter implied quite variable chances of laughter production. (ii) Some laughing subjects might not feel comfortable when recording. (iii) Evaluation of laughter episodes depended on personal inspection of the records. (iv) Sample size was relatively small and may not be representative of the general population afflicted by depression. CONCLUSIONS: Laughter may be applied as a diagnostic tool in the onset and evolution of depression and, potentially, of neuropsychiatric pathologies. The sound structures of laughter reveal the underlying emotional and mood states in interpersonal relationships.

[Teaching basic life support to the general population. Alumni intervention analysis]. / Enseñando soporte vital básico a la población general. Análisis de las intervenciones de los alumnos.

OBJECTIVES: The aim of this study was to investigate the rate at which the alumni of basic life support courses witnessed and intervened in out-of-hospital emergency situations, and to identify the variables characterizing those alumni associated with a greater number of witnessing events and interventions. An analysis of the efficiency of the courses was also carried out. DESIGN: A descriptive, cross-sectional study was made. SETTING: A district in the province of Almería (Spain). PATIENTS: Alumni of a mass basic life support training program targeted to the general population «Plan Salvavidas¼ conducted between 2003-2009. INTERVENTIONS: In 2010 the alumni were administered a telephone survey asking whether they had witnessed an emergency situation since attending the program, with the collection of information related to this emergency situation. MAIN VARIABLES OF INTEREST: Rate of out-of-hospital emergencies witnessed by the alumni. Rate of intervention of the alumni in emergency situations. Variables characterizing alumni with a greater likelihood of witnessing an emergency situation. RESULTS: A total of 3,864 trained alumni were contacted by telephone. Of 1,098 respondents, 63.9% were women, and the mean age was 26.61±10.6 years. Of these alumni, 11.75% had witnessed emergency situations, an average of three years after completing the course. Of these emergencies, 23.3% were identified as cardiac arrest. The alumni intervened in 98% of the possible cases. In 63% of the cases, there was no connection between the alumni and the victim. The majority of the emergency situations occurred in the street and in public spaces. A greater likelihood of witnessing an emergency situation was associated with being a healthcare worker and with being over 18 years of age. CONCLUSIONS: The rate of out-of-hospital emergencies witnessed by these alumni after the course was 11.75%. The level of intervention among the alumni was high. The most efficient target population consisted of healthcare workers.

[Design of a plan for patient safety in pediatric surgery service]. / Elaboración de un plan de seguridad del paciente en un Servicio de Cirugía Pediátrica.

INTRODUCTION: Patient safety is a key priority in quality management for healthcare services providers. Every patient is entitled to receive safe and effective healthcare. AIMS: The aim of this study was to design a patient safety plan for a Paediatric Surgery Department. METHODS: We carried out a literature review and we established a work group that included healthcare professionals from the Paediatric Surgery Department and the Quality and Medical Records Department. The group identified potential adverse events, failures and causes and established a rating using Failure Mode Effects Analysis. Potential risks were mapped out and a plan was designed establishing actions to reduce risks. We designated leaders to ensure the effective implementation of the plan. RESULTS: A total of 58 adverse events were identified in the Paediatric Surgery Department. We detected 128 failures that were produced by 211 different causes. The group developed a proposal with 424 specific measures to carry out preventive and/or remedial actions that were then narrowed down to 322. The group designed a plan to apply the programme, which is currently being implemented. CONCLUSIONS: The methodology used enabled obtaining key information for improvement of patient safety and developing preventive and/or remedial actions. These measures are applicable in practice, as they were designed using proposals and agreements with professionals that take active part in the care of children with surgical conditions.

Taste and olfactory status in a gourmand with a right amygdala lesion.

In a patient with a lesion of the right amygdala and temporal pole who had the characteristics of the gourmand syndrome, sensory and hedonic testing was performed to examine the processing of taste, olfactory, and some emotional stimuli. The gourmand syndrome describes a preoccupation with food and a preference for fine eating and is associated with right anterior lesions. It was found that the taste thresholds for sweet, salt, bitter, and sour were normal; that the patient did not dislike the taste of salt (NaCl) at low and moderate concentrations as much as age-matched controls; that this also occurred for monosodium glutamate (MSG); that there were some olfactory differences from normal controls; and that there was a marked reduction in the ability to detect face expressions of disgust.

Consumo de antiinflamatorios no esteroideos en pacientes que concurren por primera vez a un servicio de reumatología / Consumption of nonsteroidal anti-inflammaroty drug in patients attending for the first time a rehumatologic Unit

Introducción: El uso de antiinflamatorios no esteroideos (AINES) conlleva una mayor probabilidad de enfermedad gastrointestinal y cardiovascular en pacientes con factores de riesgo. Por tal motivo, se desarrollaron diversas recomendaciones con el fin de prevenir dichas complicaciones. Objetivo: Evaluar la frecuencia del consumo de AINES al momento de consultar por primera vez a un Servicio de Reumatología de demanda espontánea; y analizar tanto la conducta del médico así como el correcto cumplimiento de las recomendaciones para la toma de estos fármacos al finalizar la consulta. Material y métodos: Estudio observacional de corte transversal. Resultados: Se incluyeron 304 pacientes, 59,5% consumían AINES. La mayoría de estos pacientes presentaban riesgo gastrointestinal moderado/alto, sólo 28,3% recibían adecuada protección. De aquellos pacientes que recibían AINES, se consideró que requerían dicho tratamiento el 50%. Al finalizar la consulta, se tomó una conducta correcta en el 89% de los casos en relación al riesgo gastrointestinal. Conclusión: Más de la mitad de los pacientes consumían AINES. Se observó un buen cumplimiento de las recomendaciones por los médicos tratantes al finalizar la primera consulta. Sin embargo, es importante mencionar que el uso indiscriminado de AINES tanto por parte de los pacientes como por parte de los médicos sigue siendo alto.

Introduction: The use of Non-Steroidal Anti-Inflammatory DrugsNSAID (NSAIDS) leads to a higher probability of gastrointestinaland cardiovascular disease in patients with risk factors. Therefore,a number of recommendations were developed to prevent thesecomplications. The aim of this study was to evaluate the intake frequencyof NSAID by patients who attend to a rheumatology departmentfor the first time; and to analyze the attending physicians´ prescriptionas well as the correct implementation of the recommendationsfor the use of these drugs once this first visit was ended.Methods: We perform a cross-sectional observational study.Results: Three hundred and four patients were included, 59.5%were taking NSAIDs. Most of these patients had moderate/high gastrointestinalrisk and only 28.3% received adequate protection. Ofpatients receiving NSAIDs, it was considered that only 50% requiredsuch treatment. At the end of the first visit, the attending physiciansmade the correct implementation of the recommendations in 89%of cases in regard to gastrointestinal risk.Conclusion: More than half of the patients were taking NSAIDS.A good compliance with the recommendations by the attendingphysicians at the end of the first visit was observed. However, it isnoteworthy that the indiscriminate use of NSAIDs, both by patientsand by physicians, remains high.

High-protein diets and renal status in rats.

INTRODUCTION: High-protein (HP) diets might affect renal status. We aimed to examine the effects of a HP diet on plasma, urinary and morphological renal parameters in rats. MATERIAL AND METHODS: Twenty Wistar rats were randomly distributed in 2 experimental groups with HP or normal-protein (NP) diets over 12 weeks. RESULTS AND DISCUSSION: Final body weight was a 10%lower in the HP group (p < 0.05) whereas we have not observed differences on food intake, carcass weight and muscle ashes content. No significant clear differences were observed on plasma parameters, whereas urinary citrate was an 88% lower in the HP group (p = 0.001) and urinary pH a 15% more acidic (p < 0.001). Kidney wet mass was ~22 heavier in the HP group (p < 0.001). Renal mesangium area was a 32% higher in the HP group (p < 0.01). Glomerular 1 and 2 were also ~30 higher in the HP diet (p < 0.01 and p < 0.05, respectively) and glomerular area a 13% higher (p < 0.01). CONCLUSION: High-protein diet promoted a worse renal profile, especially on urinary and morphological markers, which could increase the risk for developing renal diseases in the long time.

Introducción: Las dietas hiperproteicas (HP) pueden afectar la función renal. El objetivo del presente estudio fue examinar los efectos de una dieta HP sobre parámetros renales plasmáticos, urinarios y morfológicos en ratas. Material y métodos: Veinte ratas Wistar fueron distribuidas aleatoriamente en 2 grupos experimentales con dieta HP o normoproteicas durante 12 semanas. Resultados y discusión: El peso corporal final fue un 10% inferior en el grupo de dieta HP (p < 0,05) mientras que no se han observado diferencias en la ingesta de comida, peso de la carcasa del animal y el contenido muscular de cenizas. No se observaron claras diferencias en los parámetros plasmáticos, mientras que el citrato urinario fue de un 88% inferior en el grupo de dieta HP (p = 0,001) y el pH urinario un 15% más ácido (p < 0,001). El peso del riñón en sustancia fresca fue un 22% más pesado en el grupo de dieta HP (p < 0,001). El área mesangial fue un 32% mayor en el grupo HP (p < 0,01). El floculo glomerular 1 y 2 fueron también ~ 30 mayores en la dieta HP (p < 0,01 y p < 0,05, respectivamente) y el área glomerular un 13% mayor (p <0,01). Conclusión: Una dieta hiperproteica promueve un peor perfil renal, especialmente en los marcadores urinarios y morfológico, que podrían aumentar el riesgo de desarrollar enfermedades renales a largo plazo.

Steroid 5α-reductase in adult rat brain after neonatal dihydrotestosterone administration.

Testosterone (T) is known to play an important masculinizing role in the developing brain of rat, including the regulation of 5α-reductase (5α-R) isozymes. However, the effects of dihydrotesterone (DHT), a more potent androgen than T, have not been elucidated. In this study, DHT was administered from day 5 through day 20 of postnatal life (period of postnatal sexual differentiation of the central nervous system) at doses of: 12 mg/kg/d on days 5, 6, 7, 8, 19, and 20; 15 mg/kg/d on days 9, 10, 11, 12, 16, 17, and 18; and 18 mg/kg/d on days 13, 14, and 15. In adulthood, quantitative RT-PCR was used to measure mRNA levels of 5α-R1 and 5α-R2 isozymes in the prefrontal cortex (PFC) of male and female rats with varied androgenic status. Under our study conditions, neonatal DHT administration influenced on adult PFC 5α-R isozymes levels and their regulation pattern by androgens, and this pattern was the inverse of that reported in adult neonatally T-treated rats.

Simplification of antiretroviral therapy: a good choice for our patients and the sustainability of our health care system.

OBJECTIVE: To describe the efficacy, safety, compliance and cost savings of lopinavir/ritonavir monotherapy. METHOD: Observational, descriptive and retrospective study evaluating monotherapy. Adherence was calculated using an objective method. We estimated the direct costs of dispensing non-triple therapy. RESULTS: We identified 17 patients. Interval adherence was > 95% in 9 patients, 90-95% in 2 patients, 90-85% in 2 patients, and less than 85% in 4 patients. Viral load was undetectable during weeks 12, 24, 36 and 48, except in 2 patients. The CD4 count in most analytical tests remained at > 350 cells/ml, only 1 patient had a lower figure. The average savings was 4819 Euros/patient/year (range 1116 to 8700). CONCLUSIONS: In selected patients, monotherapy can be a cost-effective treatment option.

Validación de una versión argentina del Health Assessment Questionnaire-II (HAQ-II) / Validation of an Argentine version of the Health Assessment Questionnaire-II (HAQ-II)

La versión argentina de Health Assessment Questionnaire (HAQ-A) es un instrumento útil para documentar el estado clínico, la evolución y el pronóstico funcional de nuestros pacientes con Artritis Reumatoidea (AR). Sin embargo, presenta algunas limitaciones. Esto dio lugar a una versión más simple: el HAQ-II, el cual consta de 10 preguntas. Nuestro objetivo fue determinar la reproducibilidad y validez de una versión argentina del HAQ-II en pacientes con AR. Material y métodos: Se incluyeron pacientes consecutivos con diagnóstico de AR (ACR ‘87) de 4 centros reumatológicos de Argentina. La versión original del HAQ-II fue traducida por 3 reumatólogos argentinos y retraducida al inglés por un individuo bilingüe no relacionado. La reproducibilidad del cuestionario fue evaluada en el 30% de los pacientes con un segundo cuestionario completado dentro de los 3 a 7 días de la primera visita. La validez constructiva fue evaluada comparando el HAQ-II con parámetros clásicos de actividad de la enfermedad, capacidad funcional y compromiso radiológico (medido por el método de Sharp van der Heijde). Se evaluó también el tiempo y dificultad para realizarlo, así como la confiabilidad y correlación con HAQ-A. Resultados: 97 pacientes fueron incluidos, de los cuales el 82% eran mujeres, 95% seropositivas para factor reumatoideo, 87% erosivas y 22% nodulares. La reproducibilidad del HAQ-II fue buena (r=0,94). En la correlación intraítem se halló una única redundancia (entre la pregunta 8 y 9 (r=0,92)), por este motivo la pregunta 8 fue reemplazada manteniendo excelente correlación con la versión original (r=0,99). El HAQ-II tuvo buena correlación con EVA (escala visual análoga) para dolor, EVA para actividad y articulaciones dolorosas; regular correlación con recuento de articulaciones inflamadas, menor nivel educativo y eritrosedimentación (ERS). No se observó correlación con daño radiológico.

[Preparation of a safety plan in a Clinical Medication Management Unit]. / Elaboración de un plan de seguridad en una unidad de gestión clínica del medicamento.

INTRODUCTION: Patient safety is seen as a priority in health care, and is becoming an increasingly complex activity, which involves potential risks. There is still no system that guarantees the absence of adverse events. The aim of this study was to prepare a Safety Plan for a Clinical Drugs Management Unit. METHOD: A risk assessment was made of the Clinical Drugs Management Unit over a 2 month period. To do this, a case form was distributed in which members of the Department reflected on the lack of safety in their working environment. The prioritising of the items selected from a risk matrix was analysed using the adapted Hanlon method. RESULTS: A total of 55 specific risks were identified in 8 sections of pharmacy: 11 chemotherapy unit, 11 single dose, 9 nursing sick bay kits, 8 pharmacotechnical, 5 traditional dispensing, 4 intravenous mixtures unit, 4 pharmacy care unit, and 3 pharmacy stores. After prioritisation, the Clinical Drugs Management Unit Safety Plan was prepared. It looked at 11 items: Pharmacotechnical area 7, single dose 1, nursing sick bay kits 1, traditional dispensing 1 and personnel management 1. CONCLUSIONS: Preparing a Safety Plan has enabled us to identify and prioritise our safety activities and in general to make health staff more aware of the importance of patient safety.

[Methotrexate-associated lymphoproliferative disorder presenting as oral ulcers in a patient with rheumatoid arthritis]. / Ulceras orales como manifestación clínica de proceso linfoproliferativo asociado a metotrexato en una paciente con artritis reumatoide.

Methotrexate-associated lymphoproliferative disorders are a heterogeneous group of lymphoid proliferations or lymphomas that develop in patients with autoimmune diseases treated using methotrexate. These lymphoproliferative disorders are often associated with Epstein-Barr virus infection and occasionally regress after the withdrawal of methotrexate therapy. The lymphoproliferative disorder in this case was diffuse large B-cell lymphoma, unusually presenting as oral ulcers in a 79-year-old woman on treatment with methotrexate for longstanding rheumatoid arthritis. Latent membrane protein 1 positivity was detected by immunohistochemistry and Epstein-Barr-virus encoded small RNA positivity by chromogenic in situ hybridization. Clonality was confirmed by immunohistochemistry (kappa light-chain restriction), polymerase chain reaction (monoclonal immunoglobulin H gene rearrangement), and capillary electrophoresis (GeneScan). Staging procedures were negative. Withdrawal of methotrexate therapy led to complete remission within 6 weeks, and the patient is alive and disease-free 18 months after the diagnosis was made. The oral cavity is not often involved in the initial presentation of methotrexate-associated lymphoproliferative disorders, and presentation with intraoral ulcers is very rare. We have performed a review of the literature on methotrexate-associated lymphoproliferative disorders presenting as ulcers in the oral cavity.
