ABSTRACT
OBJECTIVE: To determinate the prevalence of the main risk factors associated with development of capsular contracture after placement of breast implants in a referral center. METHOD: Retrospect study on 210 patients where sociodemographic variables, Baker's clinical scale and histopathological results were recorded. RESULTS: Statistical analysis of 210 patients was performed; 98.1% were women. The average age was 47 years (± 11), body mass index 25 (± 10) and onset of symptoms 13 years (± 8.5). Sociodemographic factors: domestic work 63.3%. Alcoholism 70% and smoking 65.7%. The main reason for consultation was pain plus deformity in 81.6%. The risk factors with statistical significance were the history of trauma, with 83.3% (p = 0.004), and the subglandular plane, with 73.8% (p = 0.0115). Histopathology: fibrous capsule 81.4%. CONCLUSIONS: The prevalence of the risk factors described are similar to those reported in the literature. Only for the history of trauma and the subglandular plane there was statistical significance.
OBJETIVO: Determinar la prevalencia de los principales factores de riesgo asociados a contractura capsular posterior a mamoplastia de aumento en un centro de referencia. MÉTODO: Estudio retrospectivo de 210 pacientes en el que se registraron variables sociodemográficas, escala clínica de Baker y resultados histopatológicos. RESULTADOS: Se realizó el análisis estadístico de 210 pacientes; el 98.1% fueron mujeres. La edad promedio fue de 47 años (± 11), el índice de masa corporal 25 kg/m2 (± 10) y el inicio de los síntomas 13 años (± 8.5). Factores sociodemográficos: labores domésticas 63.3%. Alcoholismo 70% y tabaquismo 65.7%. El principal motivo de consulta fue dolor más deformidad, en el 81.6%. Los factores de riesgo con significancia estadística fueron el antecedente de traumatismo, con un 83.3% (p = 0.004), y el plano subglandular, con un 73.8% (p = 0.0115). Histopatología: cápsula fibrosa 81.4%. CONCLUSIONES: La prevalencia de los factores de riesgo descritos es similar a lo reportado en la literatura. Solo para el antecedente de traumatismo y el plano subglandular hubo significancia estadística.

Pseudolymphomatous folliculitis (PLF) is a rare disease of cutaneous lymphoid hyperplasia, with a low index of clinical suspicion. We present the clinical case of a 19-year-old male patient, with a solitary violet erythematous nodule of 6 months of evolution, located in the right infraorbital region, without presenting another symptomatology. Histopathological examination showed a lymphocytic infiltrate that surrounds the hair follicles, sebaceous and sweat glands that focally destroy their basement membrane. PLF was diagnosed based on histological and immunohistochemical studies. In the multiple studies and case reports, the variability of the initial clinical diagnosis never corresponds to PLF, becoming a pathology with a low suspect index.

Pattern recognition receptors are preferentially expressed on APCs allowing selective uptake of pathogens for the initiation of antimicrobial immunity. In particular, C-type lectin receptors, including the mannose receptor (MR), facilitate APC-mediated adsorptive endocytosis of microbial glyconjugates. We have investigated the potential of antigenic targeting to the MR as a means to induce Ag-specific humoral and cellular immunity. hMR transgenic (hMR Tg) mice were generated to allow specific targeting with the anti-hMR Ab, B11. We show that hMR targeting induced both humoral and cellular antigenic specific immunity. Immunization of hMR Tg mice with B11 mAbs induced potent humoral responses independent of adjuvant. Injection of hMR Tg mice with mouse anti-hMR Ab clone 19.2 elicited anti-Id-specific humoral immunity while non-Tg mice were unresponsive. B11-OVA fusion proteins (B11-OVA) were efficiently presented to OVA-specific CD4 and CD8 T cells in MR Tg, but not in non-Tg, mice. Effector differentiation of responding T cells in MR Tg mice was significantly enhanced with concomitant immunization with the TLR agonist, CpG. Administration of both CpG and B11-OVA to hMR Tg mice induced OVA-specific tumor immunity while WT mice remained unprotected. These studies support the clinical development of immunotherapeutic approaches in cancer using pattern recognition receptor targeting systems for the selective delivery of tumor Ags to APCs.
