RESUMEN
Abstract Systemic amyloidosis secondary to psoriatic arthritis is rare, and published data are based mainly on case reports and are associated with increased mortality. This is the report of a patient with long-term psoriatic arthritis and chronic sialadenitis, who showed an inadequate response to therapy. The diagnosis of secondary amyloidosis was attained through biopsies of genital skin lesions. Although very rare, it is important that dermatologists and general practitioners consider the possibility of amyloidosis in patients with chronic inflammatory diseases, since an early intervention can be implemented, and thus, the prognosis of this condition can be improved.

Abstract: The oncogenic role of high-risk HPV in anogenital, head and neck, and cervical cancer is well recognized, but not in skin cancer in the general population. Some authors have demonstrated their appearance mainly on the hands and feet, particularly in the area of the nail bed, which could be due to contamination with HPV types from anogenital regions. Here, we describe a case of genital HPV associated with SCC on the nose tip in an immunocompetent young man, which was confirmed by histopathological findings and in situ hybridization. The importance of this report is to highlight the potential role of HPV in the etiology of skin cancer in an immunocompetent individual.

Introduction: This study describes the frequency of late diagnosis and HIV among children attending a pediatric AIDS clinic. Methods: Cross-sectional study in children exposed to HIV from 2005-2008. A questionnaire was given that included questions on demographics and clinical information. Results: Two-hundred twenty-one (97.8%) children were exposed to HIV during pregnancy/childbirth. A total of 193 (87.3%) children had late enrolment in the service and late access to HIV serology. The frequency of HIV was 21.3% (95% confidence interval [CI] 15.9%-26.7%). Protective factors were earlier diagnosis [odds ratio (OR)=0.17 (0.08-0.37)] and receiving complete prophylaxis [OR=0.29 (0.09-0.97)]; being born by vaginal delivery was a risk factor [OR=4.45 (1.47-13.47)]. Conclusions: There was a high frequency of late diagnosis in this patient cohort. Earlier diagnosis is an important measure for controlling HIV among children. .
