RESUMO

BACKGROUND: Pemphigus vulgaris (PV) is a potentially life-threatening mucocutaneous autoimmune disease that affects desmoglein-1 and desmoglein-3, leading to intraepithelial vesiculobullous lesions. In the oral mucosa, PV lesions can mimic other diseases such as mucous membrane pemphigoid, other forms of pemphigus, recurrent aphthous stomatitis, erythema multiforme, Stevens-Johnson syndrome, and virus-induced ulcers like herpes simplex virus (HSV), making diagnosis challenging. The co-occurrence of PV with Crohn's disease is rare and predominantly seen in younger patients. The therapeutic mainstay for both PV and Crohn's disease usually involves systemic corticosteroids combined with immunosuppressants and immunobiological drugs. Literature indicates that the use of these drugs, particularly TNF-alpha inhibitors, for managing autoimmune diseases like Crohn's can potentially induce other autoimmune diseases known as autoimmune-like syndromes, which include episodes of lupus-like syndrome and inflammatory neuropathies. There are few cases in the literature reporting the development of PV in individuals with CD undergoing infliximab therapy. CASE REPORT: A young female with severe Crohn's disease, treated with the TNF-alpha inhibitor infliximab, developed friable pseudomembranous oral ulcerations. Histopathological and immunofluorescence analyses confirmed these as PV. The treatment included clobetasol propionate and low-level photobiomodulation, which resulted in partial improvement. The patient later experienced severe intestinal bleeding, requiring intravenous hydrocortisone therapy, which improved both her systemic condition and oral lesions. Weeks later, new ulcerations caused by herpes virus and candidiasis were identified, leading to treatment with oral acyclovir, a 21-day regimen of oral nystatin rinse, and photodynamic therapy, ultimately healing the oral infections. To manage her condition, the gastroenterologists included methotrexate (25 mg) in her regimen to reduce the immunogenicity of infliximab and minimize corticosteroid use, as the patient was in remission for Crohn's disease, and the oral PV lesions were under control. CONCLUSION: Young patients with Crohn's disease should be referred to an oral medicine specialist for comorbidity investigation, as oral PV and opportunistic infections can arise during immunosuppressive therapy. The use of TNF-alpha inhibitors in patients treated for inflammatory bowel disease, such as Crohn's, should be carefully evaluated for potential side effects, including oral PV.

RESUMO

Resumen La embolia paradojal debido a una malformación arteriovenosa pulmonar (MAVP) aislada es una causa in frecuente de accidente cerebrovascular (ACV) isquémico. Las MAVP son conductos anómalos de alta circulación entre arterias y venas pulmonares, desviando sangre desoxigenada hacia la circulación sistémica y represen tan una fuente menos común de embolias paradojales, especialmente en personas jóvenes. La embolización endovascular es el tratamiento preferido para MAVP clínicamente significativas. Presentamos el caso de una mujer de 34 años con ACV isquémico talámico izquierdo. Se detectó pasaje de burbujas "en cortina" en arterias cerebrales mediante Doppler transcraneal. En ecografía intracardíaca no se encontró foramen oval permeable, motivo por el cual se avanzó con realización de angiotomografía pulmonar, la cual confirmó la presencia de MAVP. La paciente recibió tratamiento endovascular exitoso. Es esencial considerar la MAVP en el diagnóstico etio lógico del ACV isquémico, especialmente en pacientes jóvenes con signos de comunicación anormal de derecha a izquierda. Se recomienda un seguimiento periódico mediante imágenes para evaluar la posible recurrencia o cambios en la MAVP, resaltando la importancia del manejo adecuado de estas malformaciones.

Abstract Paradoxical embolism due to an isolated pulmonary arteriovenous malformation (PAVM) is a rare cause of ischemic stroke. PAVMs are abnormal high-flow connec tions between pulmonary arteries and veins, diverting deoxygenated blood into the systemic circulation and they represent a less common source of paradoxical embolisms, especially in young individuals. Endovascular embolization is the preferred treatment for clinically significant PAVMs. We present the case of a 34-year-old woman with a left thalamic ischemic stroke. Severe contrast passage was detected in cerebral arteries through transcranial Doppler. Intracardiac ultrasound did not reveal a patent foramen ovale, prompting further investigation with pulmonary CT angiography, confirming the presence of PAVM. The patient underwent successful endovascular treatment. It is essential to consider PAVM in the etiological di agnosis of ischemic stroke, especially in young patients with signs of abnormal right-to-left communication. Periodic follow-up imaging is recommended to assess potential recurrence or changes in PAVM, emphasizing the importance of appropriate management of these malformations.

RESUMO

Resumen El accidente cerebrovascular isquémico es un evento de gran importancia debido a las implicaciones y el impacto en la calidad de vida de la población afectada. Su incidencia es más alta en adultos mayores y en personas con factores de riesgo cardiovascular. Existe un grupo de pacientes jóvenes (18-44 años) sin factores de riesgo que presentan dicho evento, por lo que, en la práctica clínica, se tiende a evaluar rutinariamente las trombofilias hereditarias y adquiridas como factor etiológico principal para los eventos isquémicos en este grupo etario. No obstante, son pocos los casos donde se documenta algún trastorno de este tipo, ya que es más frecuente la presencia de otras etiologías como el cardioembolismo y trastornos vasculares. La evaluación de las trombofilias es compleja, dado el alto costo, las limitaciones técnicas para hacerlo y el impacto clínico y terapéutico incierto al documentarse estos estados. Se realiza esta revisión de tema con el fin de orientar al clínico acerca de la pertinencia de objetivar estas condiciones en el paciente joven con accidente cerebrovascular isquémico.

Abstract Acute ischemic stroke is a pathology of great complexity due to the implications and impact on the quality of life of the affected population. The incidence of this pathology is higher in older adults and in people with cardiovascular risk factors. There is a group of young patients with no risk factors who present these events. Therefore, in clinical practice, hereditary thrombophilias tend to be frequently evaluated as the main etiological factor for this age group. However, there are few cases where a disorder of this type is documented and the presence of other etiologies such as cardioembolism and vascular disorders are more frequent. Thus, the evaluation of thrombophilia is complex due to its high cost, technical limitations when evaluating, and its uncertain clinical and therapeutic impact when documented. For this reason, this review is carried out in order to guide the clinician about the relevance of objectifying these conditions in young patient with acute ischemic stroke

RESUMO

INTRODUCTION: Mucinous carcinoma is a variant of invasive breast carcinomas representing 2% of them. These tumors frequently develop in postmenopausal females; it is a rare histological variant in young patients. CASE PRESENTATION: A 25-year-old female refers a slow growth mass of 2 years of evolution. Excisional biopsy reveals a pure mucinous carcinoma with positive hormone receptors and negative HER2. She was treated with hormone therapy and surgical resection. DISCUSSION: Mucinous carcinoma is a rare variant reported in young patients. Many series report that is frequently found in postmenopausal patients. We present a case of a pure mucinous carcinoma in a 25-year-old female with the importance of being a low-frequency malignancy in young patients. CONCLUSION: Due to its benign course, it is important to know that this lesion can also present in young patients. The importance underlies in the multidisciplinary management at the right time in a proper way.

RESUMO

Background: Current methods for follow-up of Ovarian Cancer (OC) are widespread, especially with CA125, which, however, is not a perfect biomarker and thus further investigation for new methods of evaluation are warranted. The feasibility of Circulating Tumor Cells (CTCs) in advanced OC was investigated in this case report. Case presentation: A 19-year-old woman with advanced low-grade serous papillary adenocarcinoma and relapsed disease did not have a CA125 correspondent with disease relapse. CTCs were evaluated, compared with CA125 and with image exams. Relapses were not correspondent to elevations of CA125. CTCs demonstrated usefulness, being proportional to major disease relapse, especially in the peritoneum. CTCs may be used as a complementary diagnosis tool when marginal/small increases in CA-125 levels are observed. Conclusions: In OC, CTCs can be an important tool to predict recurrence, response to treatment and improve the quality of decision-making, in order to offer the best treatment to a determined group of patients (AU)

RESUMO

RESUMEN La tuberculosis con afección del sistema nervioso central es una afectación infrecuente pero muy grave de esta enfermedad, representa el 1% de todos los casos de tuberculosis. Reportamos el caso de una joven HIV negativa, con daño del sistema nervioso central de tipo miliar a nivel cerebral y sin enfermedad pulmonar. La tuberculosis puede afectar extensamente a sujetos inmunocompetentes y este fenómeno ha sido descripto en muchas series a los largo del tiempo. Ante la sospecha clínica, el seguimiento de un protocolo específico para confirmar el diagnóstico es de vital importancia para el temprano diagnóstico y correcto manejo de una situación que puede comprometer la vida y generar a largo plazo secuelas graves. Se presenta el caso por el reto diagnóstico que ha supuesto y rara presentación en paciente inmunocompetente.

ABSTRACT Tuberculosis with central nervous system involvement is an uncommon but very serious disease, with a frecuence of 1% of all cases of tuberculosis. We report the case of a young HIV negative woman, with central nervous system damage of the miliary type in the brain without lung disease. Tuberculosis can extensively affect immunecompetent subjects and this phenomenon has been described in many series over the time. In the presence of clinical suspicion, the follow-up of a specific protocol to confirm the diagnosis is of vital importance for the early diagnosis and correct management of a situation that can compromise life and generate long-term serious sequelae. The case is presented because of diagnostic challenge and a rare presentation in an immunocompetent patient.

RESUMO

Objetivo: Determinar el estado de salud general percibida por los pacientes jóvenes sometidos a artroplastia total de cadera con el implante tipo minivástago. Material y método: Se administró el cuestionario de salud SF-36 para evaluar el estado de salud percibido por 13 pacientes varones, con una media de edad de 46.62 (34 a 53) años, en los que se realizó una artroplastia total de cadera no cementada tipo MiniHip (CorinMedical) tras un seguimiento medio de 23.2 (12 a 47) meses. Los resultados obtenidos se compararon con los valores de referencia de la población española en varones de 45 a 54 años. Resultados: En las respuestas del cuestionario SF-36 se hallaron diferencias en aspectos como rol físico y rol emocional, desempeño físico, desempeño social y dolor; mientras que en el resto de los ítems la puntuación obtenida fue similar a la de la población de referencia. Discusión: Existe la necesidad de conocer en qué grado nuestras intervenciones afectan la calidad de vida de los pacientes y la manera en que son percibidas por ellos mismos para complementar la valoración de los resultados de nuestrasintervenciones. Conclusión: Es necesaria una nueva perspectiva para la valoración funcional y de calidad de vida de los pacientes jóvenes sometidos a una artroplastia total de cadera.

Objective: To determine the general health status perceived by patients undergoing total hip arthro-plasty with a mini-stem implant. Material and Methods: SF-36 health questionnaire was used to assess perceived health status in 13 male patients with a mean age of 46.62 (34-53) years after the implanta-tion of an uncemented, MiniHip® (CorinMedical) total hip arthroplasty, with a mean follow-up of 23.2 (12-47) months. Results were compared with the reference values for Spanish males aged from 45 to 54 years. Results: In the responses to the SF-36 questionnaire differences were found in areas such as physi-cal and emotional role, physical function, social function and pain; while scores for the remaining items were similar to those of the reference population. Discussion: It is important to know to what extent our surgical actions affect the quality of life of patients and how it is perceived by them to complement the results of our surgeries. Conclusion: A new perspective of function and quality of life evaluation is required in young patients undergoing total hip arthroplasty.

RESUMO

El Adenoma Pleomórfico (AP) es el tumor benigno más común de la glándula parótida, aunque se presenta frecuentemente en glándulas salivales mayores, puede encontrarse en glándulas salivales menores del paladar y del labio, siendo infrecuente en pacientes jóvenes; se detecta en muchos casos como un hallazgo casual durante el examen clínico odontológico, puede evaluarse a través de diferentes estudios imagenológicos y su diagnóstico definitivo se basa en el análisis histopatológico de la lesión. El tratamiento quirúrgico dependerá de la localización y del tamaño. En pocos casos presenta recidiva y la trasformación maligna es rara, pero es necesario realizar un seguimiento periódico a largo plazo después de su exéresis. A continuación se presenta el caso de un adenoma pleomórfico de glándula salival menor localizado en el paladar duro de una paciente de 16 años de edad, diagnosticado y tratado oportunamente mediante la resección completa con un margen adecuado de tejido sano, con un pronóstico favorable...

The Pleomorphic Adenoma (PA) is the most common benign tumor of salivary glands, although frequently in major salivary glands can be found in minor salivary glands of the palate and lip, are uncommon in young patients; often detected as an incidental finding during dental clinical, examination can be assessed by different imaging studies and definitive diagnosis is based on histopathological analysis of the lesion. The surgical treatment depends on the location and size. In a few cases presented recurrence and malignant transformation is rare, but it is necessary to regularly monitor long term after excision. A case is reported of pleomorphic adenoma of minor salivary gland located in the hard palate in a 16 year old girl, diagnosed and treated by complete resection with an adequate margin of healthy tissue, with a favorable prognosis...
