ABSTRACT Systemic lupus erythematosus is a systemic disease that generates a large number of complications of psychological origin; these can lead to inappropriate behavior patterns that can be life-threatening for patients. To describe the clinical and diagnostic elements of Rapunzael syndrome. Clinical case: a 25-year-old female patient with a diagnosis of systemic lupus erythematosus who consulted with clinical and imaging manifestations that led to the diagnosis of Rapunzel syndrome as a psychological complication in the course of systemic lupus erythematosus. Lupus erythematosus conditions a series of behaviors that can be detrimental to the health of patients; early identification of behaviors such as trichotillomania and specialized monitoring in psychology in patients with this disease is important. The clinical evolution of the patient has been very favorable and her general condition has recovered.

RESUMEN El lupus eritematoso sistémico es una enfermedad que causa un gran número de complicaciones de origen psicológico; estas pueden llevar a patrones inadecuados de conducta que pueden poner en riesgo la vida de los pacientes como el síndrome de Rapunzel. Se describen los elementos clínicos y diagnósticos de este síndrome mediante el caso de una paciente femenina de 25 años de edad, con diagnóstico de lupus eritematoso sistémico. Acude a consulta con manifestaciones clínicas e imagenológicas que permiten llegar al diagnóstico de síndrome de Rapunzel como complicación psicológica en el curso del lupus eritematoso sistémico. Se procede a realizar la intervención quirúrgica donde se halló una masa tumoral constituida por cabello humano. En la actualidad, la paciente se mantiene en seguimiento por las especialidades de reumatología, psiquiatría y psicología, y su recuperación y evolución han sido satisfactorias. El lupus eritematoso condiciona conductas que pueden ser perjudiciales para la salud de los pacientes. Es importante la identificación precoz de conductas como la tricotilomanía y el seguimiento psicológico especializado en pacientes con esta enfermedad.

The aim of this work was to study the influence of essential oil fractionation on acaricidal activity against the cattle tick Rhipicephalus (Boophilus) microplus. The citronella (Cymbopogon winterianus J.) and pepper tree (Schinus molle L.) essential oils were fractionated by vacuum distillation yielding fractions that were analyzed by the GC/MS. Laboratory tests were carried out to determine the effect of the total essential oil and fractions on larvae of the cattle tick R. (B.) microplus. The fractions 04 and 05 of the C. winterianus essential oil were the most active showing LC50 values of 1.20 and 1.34 μL/mL, respectively. The LC50 of the total oil was 3.30 μL/mL while the effect of the fractions 01, 02 and 03 was less pronounced, with LC50 values of 4.37, 4.24 and 3.49 μL/mL, respectively. The fraction 03 of the S. molle essential oil was the most active showing LC50 value of 8.80 μL/mL while the fractions 01 and 02 did not show toxic effects on the larvae.
