Comparison between urine and cervical samples for HPV DNA detection and typing in young women in Colombia

Cómbita, Aura Lucía | 2016

Urine sampling for HPV DNA detection has been proposed as an effective method for monitoring the impact of HPV vaccination programs; however, conflicting results have been reported. The goal of this study was to evaluate the performance of optimized urine HPV DNA testing in women aged 19 to 25 years. Optimization process included the use of first void urine, immediate mixing of urine with DNA preservative, and the concentration of all HPV DNA, including cell-free DNA fragments. Urine and cervical samples were collected from 535 young women attending cervical screening at health centers from two Colombian cities. HPV DNA detection and genotyping was performed using an HPV type-specific multiplex genotyping assay, which combines multiplex polymerase chain reaction with bead-based Luminex technology. Concordance between HPV DNA detection in urine and cervical samples was determined using kappa statistics and McNemar tests. The accuracy of HPV DNA testing in urine samples was evaluated measuring sensitivity and specificity using as reference the results obtained from cervical samples. Statistical analysis was performed using STATA11.2 software. The findings revealed an overall HPV prevalence of 60.00% in cervical samples and 64.72% in urine samples, HPV-16 being the most frequent HPV type detected in both specimens. Moreover, our results indicate that detection of HPV DNA in first void urine provides similar results to those obtained with cervical samples and can be used to monitor HPV vaccination trials and programs as evidenced by the substantial concordance found for the detection of the four vaccine types

Pediatric ocular myasthenia gravis: Case report and literature review

Jimeno, Verónica | 2019-12

Objective: The objective was to describe a case of ocular myasthenia gravis (MG) in a pediatric patient. Design: This is a descriptive, retrospective study and case report. Methodology: For the purpose of the case report, we searched and analyzed the literature referring to the diagnosis and treatment of ocular MG (OMG) in children. Description: A previously healthy 5‑year‑old girl presented to the emergency room because of sudden‑onset ptosis of the right upper lid without other symptoms. Her examination demonstrated fluctuating ptosis and limitation to downgaze in the right eye. Because of the fluctuation of the ptosis, OMG was suggested, and the patient was tested with ice‑pack test and neostigmine test with positive results. Treatment with pyridostigmine was initiated with a good response. Discussion: OMG has a very low incidence in pediatric patients. It is a disorder characterized by impairing neurotransmission at the neuromuscular junction that generates extraocular muscle weakness. It is important that ophthalmologists have knowledge about this disease because it is a differential diagnosis when there is a patient who has ptosis, strabismus, or limitation of movements. There are no standard diagnostic criteria for this disease; the diagnosis is based on clinical presentation and pharmacologic, serologic, and electrophysiologic tests. The treatment is based on steroids and anticholinesterase drugs. Some patients will require plasmapheresis or immunomodulators.

Téllez, Claudia L. | 2017-06-02

Objetivo: Describir el cuadro clínico de un paciente con diagnóstico de melanoma in situ en párpado inferior del ojo derecho con compromiso de conjuntiva tarsal y de vía lagrimal, llevado a cirugía micrográfi ca de Mohs diferida y posteriormente reconstrucción de párpado inferior e intubación de la vía lagrimal. Diseño: Reporte de caso. Estudio descriptivo y retrospectivo. Metodología: Con el propósito de comparar la técnica quirúrgica empleada y otras posibilidades de manejo satisfactorio, se realizó la búsqueda, revisión y análisis de literatura referente al diagnóstico patológico y al tratamiento quirúrgico descrito. Descripción: Paciente de 69 años quien presento cuadro clínico de tres añosde evolución de lesión palpebral melanótica con compromiso de borde palpebral y conjuntiva tarsal. La biopsia inicial reportó lentigo solar. Por el crecimiento y pigmentación progresiva de la lesión se realizó una segunda biopsia que confi rmó el diagnóstico de melanoma in situ. Se decidió llevar el paciente a cirugía micrográfi ca de Mohs diferida y posterior reconstrucción palpebral por parte de cirujano oculoplástico. Discusión: El melanoma es un tumor maligno desarrollado a partir de la degeneración de los melanocitos. Es además la primera causa de muerte por lesiones malignas en la piel y su tasa de incidencia ha incrementado signifi cativamente en la última década. Una gran variedad de métodos se ha utilizado para el manejo del melanoma de la región periocular, que incluyen desde la escisión quirúrgica hasta métodos destructivos como la crioterapia, radioterapia y tratamientos tópicos. La escisión quirúrgica tiene la ventaja de retirar los melanocitos alterados profundos, facilitando la detección del melanoma invasivo y permitiendo una evaluación histológica de los márgenes, disminuyendo el riesgo de recurrencia por la extracción incompleta de la lesión.
