RESUMEN

ABSTRACT Knowledge about HIV transmission and prevention is a necessary step for adopting preventive behaviors. We assessed HIV knowledge and its correlation with the perceived accuracy of the "Undetectable = Untransmittable" (U=U) slogan in an online sample with 401 adult Brazilians. Overall, 28% of participants showed high HIV knowledge level. The perceived accuracy of the U=U slogan significantly correlated with HIV knowledge. Younger participants, those reporting lower income or lower education, or who had never tested for HIV showed poorer HIV knowledge. Filling gaps of knowledge among specific populations is urgent in order to increase preventive behaviors and decrease HIV stigma.

RESUMEN

La sífilis es una enfermedad sistémica causada por la espiroqueta Treponema pallidum que compromete al sistema nervioso central en cualquier etapa y cuyas presentaciones clínicas se modificaron en las últimas décadas. Se presenta el caso de un varón de 16 años con antecedentes de conducta sexual de riesgo y sífilis hace 3 años, sin recibir tratamiento. Acude por cefalea y disminución de visión hace 4 meses. Evaluación inicial objetiva hemianopsia homónima derecha, edema papilar bilateral y retinopatía exudativa izquierda. Pruebas serológicas de sífilis reactivas, VIH: no reactivo. Resonancia magnética de encéfalo: proceso expansivo en lóbulo occipital izquierdo captador de contraste. Recibió tratamiento para sífilis por 3 días y por sospecha inicial de proceso neoproliferativo se realizó biopsia que evidenció proceso granulomatosocrónico sifilítico. En su reingreso, mostró mayor compromiso de agudeza y defecto del campo visual. Potenciales evocados visuales: ausente en ambos ojos. Se inició Penicilina G sódica por 4 semanas (por evidencia de mejoría imagenológica) asociado a corticoides, encontrando disminución serológica y discreta mejoría clínica al término del tratamiento. La neurosífilis gomatosa esuna presentación infrecuente de la sífilis terciaria debiéndose considerar como diagnóstico diferencial en lesiones expansivas intracraneales en individuos VIHseronegativos con serología de sífilis reactiva.


Syphilis is a systemic disease caused by the spirochete Treponema pallidum which can compromise the central nervous system at any stage and whose clinical presentations have been modified in recent decades. Were port the case of a 16 years old male with a 3-years history of sexual risk behavior and syphilis with no treatment who experienced headache and decreased vision for four months. Initial assessment showed right homonymous hemianopia, bilateral papilledema and left exudative retinopathy. Serological tests for syphilis: reactive HIV: non-reactive. Brain MRI revealed a single irregularly enhancing lesion in the left occipital lobe. He received treatment for syphilis for three days, and stereotactic biopsies were performed by the initial suspicion of brain tumour. Histological examination showed a chronic granulomatous consistent with neurosyphilis. In his read mission, greater affectation of acuity and visual field defect was evident. Visual evoked potentials: absent in both eyes. Penicillin G sodium was initiated for 4weeks (for evidence of improvement imagenological)associated with corticosteroids, showing serological and discrete clinical improvement at the end of treatment decreased. The gummatous neurosyphilisis a rare form of tertiary syphilis which ever considered as differential expansive intracranial lesions in HIV-seronegative individuals with reactive syphilis serology.

RESUMEN

Kaposi's sarcoma (KS) is a multifocal hemorrhagic sarcoma that occurs primarily on the extremities. KS limited to the penis is rare and a well-recognized manifestation of acquired immune deficiency syndrome (AIDS). However, KS confined to the penis is extraordinary in human immunodeficiency virus (HIV)-negative patients. We present the case of a 68-year-old man with a dark reddish ulcerated nodule on the penile skin, which was reported as a nodular stage of KS. We detected no evidence of immunosuppression or AIDS or systemic involvements in further evaluations. In his past medical history, the patient had undergone three transurethral resections of bladder tumors due to urothelial cell carcinoma since 2000 and total gastrectomy, splenectomy, and adjuvant fluorouracil/cisplatin chemotherapy for 7 months due to advanced gastric carcinoma in 2005. The patient was circumcised and has had no recurrence for 2 years.
