RESUMO

Introducción: La masturbación compulsiva provoca una cascada de sentimientos y emociones que pueden recorrer desde la culpabilidad y el rechazo a la satisfacción hasta el bienestar más placentero y deseado. Objetivo: Exponer una forma de presentación poco frecuente de un adolescente con masturbación compulsiva. Presentación del caso: Adolescente masculino de 14 años de edad, de procedencia rural y antecedentes de salud física. Evaluado en consulta de psiquiatría infanto - juvenil por realizar masturbaciones en sitios públicos, que resultaban cada vez más frecuentes, y al final de esta se producía expulsión de materia fecal. Los estudios clínicos y psicométricos confirmaron el diagnóstico de masturbación compulsiva. Conclusiones: El tratamiento se basó en el modelo cognitivo-conductual y farmacológico con imipramina. Se disminuyó la frecuencia e intensidad, así como la duración de la conducta problema. El caso clínico expuesto resulta de interés por ser poco frecuente la presencia de este trastorno dentro de la población adolescente(AU)

Introduction: Compulsive masturbation provokes a cascade of feelings and emotions that can range from guilt and refusal to satisfaction to the most pleasurable and desired well-being. Aim: To present a rare presentation of an adolescent with compulsive masturbation. Case presentation: 14-year-old male adolescent from a rural area with a history of previous physical health. He was evaluated in a child and adolescent psychiatry clinic for masturbation in public places, which became increasingly frequent and ended with the expulsion of fecal matter. Clinical and psychometric studies confirmed the diagnosis of compulsive masturbation. Conclusions: Treatment was based on the cognitive-behavioral and pharmacological model with imipramine. The frequency and intensity, as well as the duration of the problem behavior was reduced. The clinical case presented was of interest due to the infrequent presence of this disorder in the adolescent population(AU)

RESUMO

The importance of engaging the next generation in broad ranging initiatives cannot be over emphasized. This is reflected by a proliferation of publications related to next-generation, training, and healthcare professionals or scientists, with almost 2000 articles published in the last 30 years, showing a marked increase in the previous two decades. Several multilateral organizations, such as the United Nations, UNESCO and the World Health Organization, have recognized the importance of engaging youth in the global agenda. Accordingly, in 2017 The International League Against Epilepsy (ILAE) created organizational entities focused on epilepsy and the next generation of epilepsy professionals. At the core of these is the ILAE Young Epilepsy Section (YES). Its mission is to create a new generation of epilepsy experts poised to discover and deliver state-of-the-art care for people with epilepsy well into the future, with several initiatives worldwide, including education, research collaborations, and advocacy tasks, among others. The Latin American Summer School on Epilepsy, which turns 15 in 2021, has been a steady source of early career epilepsy professional participating in YES, who are moving forward the epilepsy agenda in Latin America.

RESUMO

PURPOSE: To investigate the opinions of physicians on the use of complementary and alternative medicine (CAM) in patients with epilepsy (PWE) worldwide. METHODS: Online survey addressed to neurologists and psychiatrists from different countries. RESULTS: Totally, 1112 physicians from 25 countries (different world region: Europe, North America, South America, Middle-East, Africa, Former Soviet Union Republics) participated; 804 (72.3%) believed that CAM might be helpful in PWE. The most commonly endorsed CAM included meditation (41%) and yoga (39%). Female sex, psychiatry specialization, and working in North and South America were associated with the belief that CAM is helpful in PWE. Two-hundred and forty five out of 1098 participants (22.3%) used/prescribed CAM to PWE; among them, 174 (71%) people perceived CAM to be less effective and 114 (46.5%) people found CAM to be safer than conventional antiseizure medications (ASMs). The most common reasons to prescribe CAM for PWE were: to satisfy the patient (49.9%), dissatisfaction with the efficacy (35.6%), and dissatisfaction with the adverse effects (31.2%) of conventional therapies. CONCLUSION: Although the evidence supporting the use of CAM for the treatment of epilepsy is extremely sparse, most physicians worldwide believe that it could be integrated with the use of conventional ASMs, at least in some patients. High-quality controlled trials are warranted to provide robust evidence on the usefulness of CAM options in PWE.

RESUMO

OBJECTIVES: In this international study, we aimed to investigate the opinions of physicians dealing with patients with functional seizures (FS) worldwide on working restrictions and disability benefits eligibility. METHODS: International online survey of neurologists/mental health professionals from Argentina, Venezuela, Colombia, Italy, France, Iran, Iraq, United Arab Emirates (UAE), Qatar, Saudi Arabia, Georgia, and Russia. RESULTS: Six hundred and twenty-seven physicians from 12 countries participated in the study. Working as a neurologist was a predictor to think that patients with FS should not be counseled to avoid performing all jobs or professions as long as they have active disease (OR: 0.46; 95% CI: 0.30 to 0.68; p < 0.001). Having managed more than 200 patients was associated with the opinion that patients should not be counseled to avoid performing any type of work (OR: 2.17; 95% CI: 1.02 to 4.59; p = 0.043). Working as a psychiatrist/psychologist was associated with the idea that patients with FS should be qualified for disability benefits (OR: 1.97; 95% CI: 1.21-3.21; p = 0.006), and receive these benefits lifelong (OR: 0.43; 95% CI: 0.22-0.84; p = 0.014). CONCLUSION: Neurologists and mental health professionals have different attitudes and opinions toward working restrictions and disability benefits for patients with FS. Further studies should investigate the reasons for these differences, and propose solutions to avoid discrimination and unequal access to employment and disability benefits.

RESUMO

Antiepileptic drug side effects are frequent, 42% of them corresponding to cosmetic changes. The most frequent effects are weight gain, gingival hyperplasia, and hair loss. Hair changes in texture or colour are rarely reported in the literature. We present a case of hair curling after the introduction of perampanel. A 13-year-old girl with genetically confirmed Pitt-Hopkins syndrome with uncontrolled seizures, while on treatment with levetiracetam and valproic acid, was started on perampanel, reaching seizure control. After a few weeks of the introduction of the new antiepileptic drug, she developed hair curling. Hair curling is a rare cosmetic side effect, reported mainly in patients under valproic acid treatment. Perampanel is a recently introduced pharmaceutical molecule with no prior reports of hair changes as a side effect. There is no clear explanation for this side effect, but it should be discussed with patients taking valproate whenever perampanel is added to the treatment.

RESUMO

OBJECTIVE: Forced normalization (FN) is an intriguing phenomenon characterized by the emergence of psychiatric disturbances following the establishment of seizure control or reduction in the epileptic activity in a patient with previous uncontrolled epilepsy. We aim to describe the clinical characteristics of the condition. METHODS: We conducted a systematic review on MEDLINE, EMBASE, Cochrane, and Scielo from January 1953 to January 2018. Clinical, electrographic, and imaging data were gathered. We considered all outcomes in children and adults. We performed no meta-analyses due to the limited available data. RESULTS: Of 2606 abstracts identified, 36 fulfilled the FN diagnostic criteria; 193 FN episodes were evaluated and 77 of them were analyzed extensively. Sixty percent of cases were female. Mean age ± standard deviation (SD) was 28.3 ± 14.2 years. The majority of patients had focal (80%) symptomatic (44%) epilepsy. Most patients reported a high ictal frequency (58%) and were on polytherapy (51%). Patients presented psychosis (86.4%), mood disorders (25.8%), and dissociation (4.5%) as the main manifestations. In the psychosis group, persecutory (52.6%) and reference (47.3%) delusions were frequent. FN was provoked by an antiepileptic drug (AED) (48.5%) mainly levetiracetam, epilepsy surgery (31.8%), or vagus nerve stimulation (13.6%). Treatment was homogeneous including anticonvulsant withdrawal (47%) or taper (25%); antipsychotics were initiated in the majority of cases (73%). Psychiatric symptoms were partially controlled in 35%, with complete resolution of symptoms in the remaining 65% of cases. The majority of patients (87%) with AED trigger and withdrawal presented complete resolution of symptoms in comparison to 28.5% of patients triggered by surgery. SIGNIFICANCE: Forced normalization is an entity whose pathophysiology remains uncertain. Antipsychotic drug use does not predict complete resolution of psychiatric symptoms in comparison with AED withdrawal. Although there is a positive response to treatment in patients with FN triggered by drugs, the prognosis is obscure in patients with surgery triggered FN.

RESUMO

Resumen El síndrome de piernas inquietas (SPI) es un trastorno sensitivo y motor en el que el paciente refiere un deseo incontenible de mover las extremidades, que puede estar acompañado por una sensación desagradable, mal definida, y hasta en el 50 % de los casos con dolor, difícil de ubicar en un punto específico, y que inicialmente se manifiesta en las piernas. Se presenta principalmente en las noches impidiendo el sueño y subsecuentemente afectando la calidad de vida del paciente. Clásicamente se divide en síndrome de piernas inquietas primario y secundario, por la presencia o no de enfermedades concomitantes relacionadas con el tratamiento y pronóstico del SPI. Esta enfermedad tiene una incidencia en la población general de 9 a 22 pacientes por cada 1.000 personas al año (equivalente a 1,7 % por año); con una prevalencia de 5-13 % de la población general. El diagnóstico del SPI se realiza mediante el uso de los criterios establecidos por el Grupo Internacional de Estudio de SPI, divididos en esenciales y de soporte. Su tratamiento tiene como piedra angular a los agonistas dopaminérgicos, y otros medicamentos como el gabapentin enacarbil que han ganado terreno en los últimos años. La importancia del conocimiento de la enfermedad radica en el impacto negativo que ejerce sobre la calidad de vida de los pacientes afectados en general, y el aumento de la mortalidad en los pacientes con comorbilidad de enfermedad renal terminal en particular. Su diagnóstico es clínico y debe buscarse como causa de insomnio.

Summary Restless leg syndrome (RLS) is a sensory motor disorder in which the patient referred an urge to move the limbs, which may be accompanied by an ill-defined sense, and up to 50% of cases with pain, difficult to locate, and initially manifests in the legs. It occurs mostly at night, disrupting sleep and subsequently affecting the quality of life of patients. It is classically divided into primary and secondary restless legs syndrome, based on the presence or absence of comorbidities related to the treatment and prognosis of RLS. This disease has an incidence in the general population of 9-22 patients per 1,000 people per year (equivalent to 1.7% per year); with a prevalence of 5-13% of the general population. The diagnosis of RLS is done by using the criteria established by the International RLS study group, divided into essential and supportive. The treatment's cornerstone are dopamine agonists, and other drugs, such as gabapentin enacarbil that have been used more recently. The importance of the disease lies in the negative impact it has on the quality of life of affected patients in general, and increased mortality in patients with end stage renal disease comorbidity in particular.

RESUMO

TB, caused by Mycobacterium tuberculosis (MTB), is one of the major global infectious diseases. For the pandemic control, early diagnosis with sensitive and specific methods is fundamental. With the advent of bioinformatics' tools, the identification of several proteins involved in the pathogenesis of TB (TB) has been possible. In the present work, the MTB genome was explored to look for molecules with possible antigenic properties for their evaluation as part of new generation diagnostic kits based on the release of cytokines. Seven proteins from the MTB proteome and some of their combinations suited the computational test and the results suggested their potential use for the diagnosis of infection in the following population groups: Cuba, Mexico, Malaysia and sub-Saharan Africa. Our predictions were performed using public bioinformatics tools plus three computer programs, developed by our group, to facilitate information retrieval and processing.

RESUMO

Mycobacterium tuberculosis is a facultative intracellular pathogen for which cell-mediated immunity is considered the major component of the immune response. For many decades, the prevailing scientific view has been the antibodies have little or no role in modifying the course of M. tuberculosis infection. In recent years, several studies have challenged this dogma, and there is a body of evidence that supports a role of antibodies against M. tuberculosis. In the present work, we evaluated the protective activity of two monoclonal antibodies (TBA61 and TBA84). Here, we chose the intratracheal model of pulmonary infection to evaluate bacterial load and morphometric and histological changes in the lungs of treated mice. Data obtained revealed the reduction of bacterial load and milder morphometric and histopathological changes in mice treated with TBA61 at 21 days post-infection with M. tuberculosis H37Rv compared to those treated with TBA84 and control mice. These results allow continuing exploring the potential use of monoclonal antibodies as prophylactic and therapeutic agents against intracellular pathogens such as M. tuberculosis.

RESUMO

We employed a prime-boost regimen in combination with the expression library immunization protocol to improve the protective effectiveness of a genomic library used as immunogen. To demonstrate the feasibility of this novel strategy, we used as a prime a serogroup B Neisseria meningitidis random genomic library constructed in a eukaryotic expression vector. Mice immunized with different fractions of this library and boosted with a single dose of meningococcal outer membrane vesicles elicited higher bactericidal antibody titers compared with mice primed with the empty vector. After the boost, passive administration of sera from mice primed with two of these fractions significantly reduced the number of viable bacteria in the blood of infant rats challenged with live N. meningitidis. The method proposed could be applied to the identification of subimmunogenic antigens during vaccine candidate screening by employing expression library immunization.
