RESUMEN

Background: Multiparametric magnetic resonance imaging improves the performance of prostate cancer (PCa) diagnostics through a better selection of patients. Objectives: The aim of the study was to study the detection rate (DR) of systematic and targeted cognitive biopsies in a cohort with the previous negative systematic biopsies. A secondary objective was to describe the value of prostate-specific antigen density (PSAd) in the detection of clinically significant PCa (CSPCa). Methods: We designed a prospective, single-center, and comparative study to determine the DR of systematic and targeted cognitive biopsies. The clinical and pathological characteristics of each patient were described. Results: A total of 111 patients with Prostate Imaging Reporting and Data System lesions > 3 were included in the study. PCa was detected in 41.4% (46 of 111 patients); 42 (91.3%) were detected by systematic biopsy and 30 (65.2%) by targeted biopsy. CSPCa was detected in 26 (23.4%), 23 (88.5%) by systematic biopsy, and 21 (76.9%) by targeted biopsy. PSAd > 0.15 was directly associated with CSPCa. Conclusion: The detection of PCa by systematic biopsy in this series was higher than 80%; hence, its routine use should not be replaced by targeted biopsy, since it continues to be the cornerstone of the diagnosis in patients with prior negative biopsies.

RESUMEN

BACKGROUND: Although return of function has been reported in patients undergoing proximal forearm transplantations (PFTs), reports of long-term function are limited. In this study, we evaluated the clinical progress and function 7 years postoperatively in a patient who underwent bilateral PFT. CASE PRESENTATION: A 58-year-old man underwent bilateral PFT in May 2012. Transplantation involved all of the flexor and extensor muscles of the forearm. Neurorrhaphies of the median, ulnar, and radial nerves were epineural and 7 cm proximal to the elbow. Immunosuppressive maintenance medications during the first 3 years postoperatively were tacrolimus, mycophenolate, and steroids, and later, tacrolimus, sirolimus, and steroids. Forearm function was evaluated annually using the Disabilities of the Arm, Shoulder, and Hand; Carroll; Hand Transplantation Score System; Short Form-36; and Kapandji scales. We also evaluated his grip and pinch force. RESULTS: Postoperatively, the patient developed hypertriglyceridemia and systemic hypertension. He experienced 6 acute rejections, and none were resistant to steroids. Motor function findings in his right/left hand were: grip strength: 10/13 kg; key pinch: 3/3 kg; Kapandji score: 6/9 of 10; Carroll score: 66/80; Hand Transplantation Score System score: 90/94. His preoperative Disabilities of the Arm, Shoulder, and Hand score was 50 versus 18, postoperatively; his Short Form-36 score was 90. This function improved in relation with the function reported in the second year. CONCLUSIONS: Seven years following PFT, the patient gained limb strength with a functional elbow and wrist, although with diminished digital dexterity and sensation. Based on data presented by other programs and our own experience, PFT is indicated for select patients.

RESUMEN

BACKGROUND: Patients with proximal forearm and arm transplantation have obtained and/or maintained function of the elbow joint and full active range of motion of the extrinsic muscles of the hand, but with diminished protective sensibility and a lack of good function of the intrinsic muscles. These patients have improved function, as measured by the Disabilities of the Arm, Shoulder and Hand questionnaire. METHODS: We report the case of a 52-year-old man who suffered a high-voltage electrical burn requiring amputation of his upper limbs. He underwent bilateral proximal forearm transplantation in Mexico City in May 2012. RESULTS: At 2-year follow-up, immunosuppressive treatment has not led to metabolic, oncologic, or infectious complications. Keloid scars developed at the graft-recipient interface. There have been 4 acute rejections: the fourth was treated with methylprednisolone, rituximab, and immunoglobulin. Chronic rejection has not been detected. The extrinsic muscles of the wrist and digits have good function. Although the intrinsic muscles demonstrated electrical activity 15 months postoperatively, clinically, they are nonuseful. After 2 years, hand function is sufficient to allow the patient to grasp lightweight and medium-sized objects. The patient's Disabilities of the Arm, Shoulder and Hand questionnaire score improved from 50.00 points to 30.83 points, and his Hand Transplantation Score System rating is good, at 69/73 (right/left) of 100. The patient and his family are very satisfied with the functional and aesthetic outcomes. CONCLUSIONS: Upper arm or proximal forearm transplantation is a reconstructive option for patients who have experienced amputation because of trauma.

RESUMEN

Objetivo: Presentar nuestra experiencia en el tratamiento de la insuficiencia venosa, empleando el Ecodoppler para el diagnóstico.Antecedentes: El tratamiento de la insuficiencia venosa hasta hace algunos años se basaba en la manifestación de la enfermedad, hoy en día hemos comprendido la hemodinamia de la insuficiencia venosa y podemos efectuar tratamientos funcionales conservando la circulación venosa superficial.Método: De noviembre de 1997 a noviembre del 2000 realizamos un Ecodoppler venoso a 80 pacientes con sintomatología atribuible a insuficiencia venosa, el estudio se clasificó como normal, incompetencia leve, moderada y severa. Se correlacionó con la clínica y se decidió el tratamiento.Resultados: De los 80 pacientes 54 fueron tratados conservadoramente, 32.5 por ciento fueron intervenidos quirúrgicamente. Los procedimientos realizados fueron: ligaduras altas, ligadura de comunicantes y fleboexcéresis limitadas. Los resultados funcionales fueron excelentes en 80.7 por ciento, buenos en 11.5 por ciento y malos en 7.6 por ciento; 19.2 por ciento requirió tratamiento estético complementario.Conclusiones: El Ecodoppler venoso permite determinar la causa de la insuficiencia venosa. Se pueden obtener resultados funcionales aceptables, permite una evaluación fisiológica completa del sistema venoso y se logra conservar safenas.
