ABSTRACT

La sífilis es una enfermedad de transmisión sexual altamente contagiosa con importantes complicaciones, pero con tratamiento efectivo en etapas tempranas. Actualmente, representa un problema de salud pública. La prevalencia reportada en EEUU desde el año 2008 es de 4,5 casos/100.000 habitantes, con una incidencia 10.6 millones de casos cada año, especialmente en hombres que mantienen relaciones sexuales con hombres (HSH) y pacientes portadores de VIH (PVIH). Los métodos diagnósticos basados en test moleculares aún no han sido validados para el diagnóstico de sífilis, lo que ha permitido establecer tres esquemas serológicos con diferentes rendimientos, según prevalencia poblacional. Desde este punto de vista, el screening reverso pareciera ser útil en población de alto riesgo, y el screening tradicional para la población general.


Syphilis is a sexual transmitted disease highly contagious with important complications that can be prevented with an adequate treatment in early stages. Syphilis has become a public health issue, in the USA its incidence has increased from the 2001, with a rate in the 2008 of 4,5 cases/100000 people, with a greater prevalence in men who have sex with men (HSH) and people infected by HIV (PVIH). Despite molecular detection test are used for the diagnostic of many diseases, in syphilis we still using serologist test. There are three different schemes with different per-formance depending in the prevalence of syphilis in the population. In this setting reverse screening is the most adequate method for high prevalence versus traditional method that is better in general population.

ABSTRACT

La Enfermedad de Paget extramamaria de la vulva es una neoplasia poco frecuente que representa solo el 1% de los cánceres de vulva. Clínicamente, se caracteriza por una placa eritematosa, bien definida, con erosiones y ulceraciones. El síntoma más frecuente es el prurito. Esta clínica tan inespecífica puede retrasar el diagnóstico, además de inducir a tratamientos inadecuados. El diagnóstico se realiza con estudio histopatológico e inmunohistoquímica, la cual orienta si es primario de piel o metástasis de otro cáncer, usualmente genitourinario o gastrointestinal subyacente. Actualmente no hay guías clínicas de tratamiento, pero dentro de las opciones la más aceptada es la cirugía de Mohs. Otros tratamientos incluyen uso de imiquimod, láser CO2, quimioterapia tópica o local, radioterapia o terapia fotodinámica. Cuando se trata de una enfermedad de Paget extramamaria primaria, el pronóstico es excelente y la mayoría de los pacientes fallece por otra condición. En cuanto a la enfermedad invasora, tiene una mortalidad de 13-18% con sobrevida a 5 años de 72% (1)

ABSTRACT

Chronic eosinophilic pneumonia (CEP) is uncommon and predominantly seen in women. More than 6% of eosinophils in peripheral blood and more than 25% in bronchoalveolar lavage are diagnostic criteria. Secondary causes of hypereosinophilic pneumonia must be ruled out. We report a 72-year-old non-smoker man presenting in the emergency room with a history of cough, fever, and moderate dyspnea. He was not taking any medication. A chest-X ray showed a left lower lobe (LLL) consolidation, and was started on broad-spectrum antibiotics with a presumptive diagnosis of pneumonia. There was no improvement after therapy. A chest CT scan showed increased LLL consolidation and new left upper lobe ground glass opacities as well as a moderate left pleural effusion. Flexible bronchoscopy was performed and bronchoalveolar lavage showed 95% eosinophils, and had negative cultures. No parasites were identified. Transbronchial biopsies demonstrated eosinophil accumulation in alveoli and interstitium and pleural fluid was composed by 85% eosinophils. With the diagnosis of CEP, systemic corticosteroids were used with favorable clinical and radiological response.

ABSTRACT

El Síndrome Graham-Little-Piccardi-Lasseur (GLPLS) corresponde a una variante clínica del llamado Liquen plano pilar y se caracteriza por presentar alopecia cicatrizal progresiva de cuero cabelludo con las características del Liquen plano pilar, alopecia no cicatrizal que compromete axilas y pubis, y erupción folicular liquenoide en tronco, extremidades, cara y/o cejas. Presentamos el caso de una paciente de 19 años que ha sido diagnosticada con GLPLS y cuyo curso ha sido de difícil manejo.


The Graham-Little-Piccardi-Lasseur Syndrome (GLPLS) corresponds to a clinical variant of Lichen planopilaris and is characterized by progressive scarring scalp alopecia with features of flat lichen, non-scarring alopecia localized in the armpits and pubis, and lichenoid follicular eruption in trunk, extremities, face and / or eyebrows. We present the case of a 19-year-old female patient who has been diagnosed with GLPLS and whose course has been difficult to manage.
