RESUMO
INTRODUCTION: Salvage radiotherapy (SRT) after radical prostatectomy for prostate cancer (PCa) is recommended as soon as PSA rises above 0.20 ng/ml, but many patients (pts) still experience local macroscopic relapse. The aim of this multicentric retrospective analysis was to evaluate the role of SRT in pts with macroscopic relapse. MATERIALS AND METHODS: From 2001 to 2016, 105 consecutive pts with macroscopic PCa relapse underwent SRT ± androgen deprivation therapy (ADT). Mean age was 72 years. At time of relapse, 29 pts had a PSA value < 1.0 ng/mL, 50 from 1.1 to 5, and 25 pts > 5. Before SRT, 23 pts had undergone 18F-choline PET and 15 pts pelvic MRI. Ninety-four pts had prostatic bed relapse only, and four nodal involvement. Fifty-one pts were previously submitted to first-line ADT, while 6 pts received ≥ 2 lines. RESULTS: At a median follow-up of 52 months, 89 pts were alive, while 16 were dead. Total RT dose to macroscopic lesions was > 70 Gy in 58 pts, 66-70 Gy in 43, and < 66 Gy in 4 pts. In 72 pts, target volume encompassed only the prostatic bed with sequential boost to macroscopic site; 33 pts received prophylactic pelvic RT. Ten-year overall survival was 76.1%, while distant metastasis-free survival was 73.3%. No grade 4-5 toxicities were found. CONCLUSIONS: SRT ± ADT for macroscopic relapse showed a favorable oncological outcome supporting its important role in this scenario. Data from this series suggest that SRT may either postpone ADT or improve results over ADT alone in appropriately selected pts.

OBJECTIVE: To describe 10 patients with skin and soft tissue infection caused by rapidly growing mycobacteria after cosmetic liposuction and liposculpture. DESIGN: Case series. SETTINGS: Eight private geographically separate surgical facilities from a single metropolitan area. PATIENTS: Eight patients with definite and 2 with presumptive cases of skin and soft tissue infection caused by rapidly growing mycobacteria after cosmetic surgery procedures during a 24-month period. Microorganisms were isolated from the purulent drainage obtained from wounds or fistulas in 8 cases and were identified as Mycobacterium fortuitum (3 cases) and Mycobacterium abscessus (5 cases) by routine microbiologic techniques. Acid-fast bacilli were observed on Ziehl-Neelsen-stained smears in the 2 remaining cases, but these ultimately failed to grow. In 2 of the surgical units, no apparent environmental predisposing factors were identified after thorough microbiologic environmental investigation. Clinically, all patients exhibited signs of inflammation, microabscesses, and purulent wound drainage within 24 months of abdominal and/or thigh liposuction or homologous fat tissue injection. INTERVENTION: A combined therapeutic approach including surgical drainage, debridment, and prolonged (>3 months) treatment with combined antimicrobial agents including clarithromycin was used in all cases. RESULTS: Nine of 10 patients responded to the combined therapeutic approach, and no evidence of infection was present during at least 12 months of follow-up. CONCLUSION: To our knowledge, this is the first series of patients with rapidly growing mycobacterial infections to be described after liposuction and liposculpture. Rapidly growing mycobacteria should be included in the differential diagnosis of skin and soft tissue infection after cosmetic surgery.

Se revisaron en forma retrospectiva las histórias clínicas de todos los pacientes en los cuales se aisló Hansenula anómala en los hemocultivos realizados en el Laboratorio de Microbiología del Hospital Privado Centro Médico de Caracas, en el lapso de 2 años y medio, comprendido entre agosto 1994 y febrero 1997. De 57 pacientes se obtuvo 64 hemocultivos positivos, aislándose 64 especies de Candida. Hansenula anómala se obtuvo en 15 hemocultivos de 15 pacientes diferentes, representando un 26,3 por ciento del total de pacientes, un 23,4 por ciento del total de las candidas y un 30,6 por ciento de las variedades no albicans. La Candida albicans se aisló en 15 pacientes (26,3 por ciento del total). De los pacientes que presentaron Hansenula anómala en sus hemocultivos, el 100 por ciento cumplieron con criterios clínicos de severidad. El rango de edad estaba comprendido entre 1 mes y 76 años, con una media de 43, de los cuales 6 eran masculinos y 9 femeninos. De este grupo de pacientes, 12 ingresaron con patología abdominal, siendo intervenidos quirúrgicamente 10 de estos. De los tres pacientes restantes, dos ameritaron cirugía no abdominal. Todos los pacientes recibieron antibióticos de amplio espectro, nutrición parenteral total y le fue colocado catéteres centrales. Nueve pacientes (60 por ciento) tuvieron criterios de sepsis. Los días de hospitalización oscilaron entre 7 y 101 días, con un promedio de 37. Doce pacientes ameritaron ingreso a la Unidad de Terapia Intensiva. Se inició Anfotericina B en 8 pacientes, con buena respuesta en el 100 por ciento. Seis pacientes recibieron como terapia inicial Fluconazol: 2 con respuesta satisfactoria; 1 fallecido no relacionado con la infección por Hansenula anómala y los tres restantes ameritaron cambio a Anfotericina B. Un paciente no recibió tratamiento antifúngico desconociéndose su evolución.
