Rabdomiólisis en un paciente con enfermedad de McArdle / Rhabdomyolysis in a patient with McArdle's disease

INTRODUCCIÓN: La enfermedad de McArdle o glucogenosis tipo V es una enfermedad rara debida al déficit de miofosforilasa muscular, lo que produce incapacidad para degradar el glucógeno a este nivel. Los pacientes presentan fatiga, dolor y calambres de forma habitual. Además, tras un ejercicio intenso o situación estresante, están expuestos a lisis celular. Esto se puede manifestar en forma de mioglobinuria y rabdomiólisis, síndrome clínico potencialmente grave si no se trata con rapidez. VALORACIÓN: Se presenta el caso de un varón de 38 años con enfermedad de McArdle y rabdomiólisis secundaria a la realización de ejercicio, que precisó atención en el Servicio de Urgencias durante 24 horas, así como su posterior ingreso en Unidad de Hospitalización. Se realizó una valoración enfermera siguiendo el modelo de cuidados de Virginia Henderson. DIAGNÓSTICO: Se priorizaron los diagnósticos enfermeros: (00016) deterioro de la eliminación urinaria, (00092) intolerancia a la actividad, (00093) fatiga y (00132) dolor agudo; y la complicación potencial: riesgo de fallo renal agudo. PLANIFICACIÓN: Se elabora Plan de Cuidados siguiendo la metodología NANDA-NIC-NOC, con especial atención a las alteraciones en la eliminación y en el sistema musculoesquelético. Se realiza monitorización de la diuresis. Se realiza reposición de líquidos y se administra medicación analgésica. DISCUSIÓN: Existe escasa literatura sobre los cuidados enfermeros de pacientes con enfermedad de McArdle, lo que ha limitado la comparación de nuestros resultados con los de otros autores, sin embargo, dada la buena respuesta del sujeto mediante reposición de líquidos, un óptimo control del dolor y el reposo demostraron una rápida recuperación del paciente

INTRODUCTION: McArdle's disease or glycogenosis type V is a rare disease due to deficiency of muscle myophosphorylase leading to inability to degrade glycogen at this level. Patients have fatigue, pain, and cramps on a regular basis. In addition, after intense exercise or stressful situation, they are exposed to cellular lysis. This can occur in the form of rhabdomyolysis and myoglobinuria, a potentially serious clinical syndrome if not treated quickly. CASE EVALUATION: We present the care plan of a 38-year-old man with McArdle's disease and secondary rhabdomyolysis on physical exercise, which required attention in the Emergency Department for 24 hours, as well as his subsequent admission to the ward. A nursing evaluation was performed following the care model of Virginia Henderson. DIAGNOSIS: Priority was given to nurse diagnoses: (00016) deterioration of urinary elimination, (00092) activity intolerance, (00093) fatigue and (00132) acute pain; and potential complication: risk of acute renal failure. PLANNING: The Care Plan is developed following the NANDA-NIC-NOC methodology, with special attention to alterations in the elimination and musculoskeletal system. The diuresis is monitored. Fluid replenishment is performed, and analgesic medication is given. DISCUSSION: There is little literature on the nursing care of patients with McArdle's disease, which has limited the comparison of our results with those of other authors. However, given the good response of the subject through fluid replacement, optimal pain control and rest, they made a rapid recovery

Depressive and anxiety disorders in chronic hepatitis C patients: reliability and validity of the Patient Health Questionnaire.

UNLABELLED: Depression and anxiety in patients with hepatitis C virus (HCV) infection influence their health-related quality of life and their adherence to antiviral treatment. OBJECTIVE: To study the psychometric properties of the Patient Health Questionnaire (PHQ) as a screening instrument for depression and anxiety in HCV patients. METHODS: Criterion validity, using the structured clinical interview for DSM-IV-Axis I (SCID-I) to diagnose depression and anxiety disorders as diagnostic standard, was evaluated for both summed and algorithm-based PHQ in 500 HCV patients. Correlations with quality of life (Short-Form-36 Health Survey; SF-36) and severity of illness (Hospital Anxiety and Depression Scale; HADS) were calculated to assess construct validity. Test-retest reliability and patients' reaction to the PHQ were assessed in 120 HCV patients. RESULTS: Twenty-three percent of patients (N=114) had a psychiatric disorder (any depressive disorder=18.2%; major depressive disorder=6.4%; generalized anxiety disorder=7.0% and panic disorder=5.8%). The questionnaire demonstrated good test-retest reliability for any depressive disorder (k=.847), major depressive disorder (k=.784), generalized anxiety disorder (k=.787), panic disorder (k=.848), and for any psychiatric disorder (k=.847). There was good agreement between PHQ and SCID-I diagnoses (for any PHQ disorder, k=.821; overall accuracy=90.43%, sensitivity=83.84%; specificity=97.01%). Patients with any PHQ disorder had higher impairment on the SF-36 (p<.001). HADS depression and anxiety scores showed high correlations with PHQ depression (p<.001) and anxiety (p<.001) scores respectively. PHQ administration was well accepted by 97% of patients. CONCLUSIONS: The Spanish version of the PHQ is a reliable, valid, and useful screening instrument to detect depression, generalized anxiety and panic disorders in HCV patients.
