Pulmonary metastasectomy has potential survival benefit for patients with metastatic colorectal carcinoma. Low morbidity and mortality rates, contrasting with lack of any other effective therapy, justify aggressive surgical management. Single deposits, DFI >36 months and normal prethoracotomy serum CEA were significant independent prognostic factors.

Abordagem endoscópica de perfuração do cólon por cateter de derivação ventrículo-peritoneal: caso clínico e revisão da literatura Palavras Chave Derivação ventrículo-peritoneal · perfuração cólica · colonoscopia ResumoOs autores descrevem o caso de uma mulher de 42 anos com perfuração do cólon por cateter de derivação ventrí-culo-peritoneal (DVP) colocado 28 anos antes. No contexto de meningite aguda a Escherichia coli , o estudo complementar com tomografia computadorizada abdominal identificou a extremidade distal do cateter de DVP no interior do lúmen do cólon esquerdo. Após remoção da extremidade ventricular do cateter, optou-se pela tentativa de extração da extremidade intra-cólica por colonoscopia. Durante a extração do cateter com ansa de polipectomia, constatou-se secção do mesmo no local de entrada na parede cólica, observando-se um pequeno orifício. Keywords Ventriculoperitoneal shunt · Intestinal perforation · Colonoscopy AbstractThe authors report the case of a 41-year-old woman with a colonic perforation due to a ventriculoperitoneal shunt (VPS) catheter. Left-sided colonic perforation was diagnosed by abdominal computed tomography 28 years after shunt placement, following acute meningitis caused by Escherichia coli . The proximal end of the VPS was exteriorized and it was decided to remove the distal end by colonoscopy. After pulling out the catheter with a polypectomy snare, it broke at the site where it was entering the colon, leaving a small perforation in the colonic wall which was closed with 2 endoclips. The endoluminal fragment of the catheter, being 20 cm in length, was removed through the rectum. The patient is asymptomatic at the 12-month follow-up. A review of the literature regarding 9 endoscopically managed cases of digestive tract perforation caused by VPS is presented. Procedeu-se ao encerramento da perfuração com 2 endoclips e extração do fragmento livre endoluminal do cateter, com cerca de 20 cm, pelo reto. A doente permanece assintomática após 12 meses de seguimento. Uma revisão da literatura identificou 9 casos de perfuração do tubo digestivo por cateter de DVP tratados com endoscopia.

Toxigenic strains of Clostridium difficile may be disseminating. Here we prospectively screened patients with nosocomial diarrhoea in two hospitals in Brazil. To identify C. difficile polymerase chain reaction ribotypes 027/078 strains, we used high resolution melting and multiplex polymerase chain reaction. Among 116 screened patients, 11 were positive for C. difficile. The polymerase chain reaction ribotypes 027/078 strains were not identified in this study.

Background: Tuberculosis (TB) is a prevalent infection after kidney transplantation (KT) in high-burden countries. Latent tuberculosis infection (LTBI) screening includes previous TB history, chest radiograph findings, and tuberculin test (TST) and/or interferon-gamma release assays (IGRAs) results. We aimed to compare our routine LTBI screening of KT candidates and living donors (LD) with their IGRA results, and evaluate if this would improve isoniazid (INH) treatment referral. Methods: We evaluated adult KT candidates and LD with complete routine LTBI screening and QuantiFERON-TB® Gold In-Tube (QFT) testing. Blood samples were collected from April 4th, 2014 to October 31st, 2018, with follow-up until October 31st, 2019. Results: There were 116 KT recipients, with 30% QFT-positive results. Positive QFT was associated with past TB history (p=0.007), positive TST (p<0.0001), residual radiographic lesions (p=0.003), and diabetes (p=0.035). There were 25 LD, 40% had positive QFT. Positive QFT was associated with a positive TST (p=0.002). Positive QFT results increased INH referral in 80%. Post-transplant TB incidence was 2.6% in a median follow-up of 2 (1-33) months. No variables were associated with post-transplant TB. TB patients had inferior, although non-significant, 5-year graft survival (66.7% vs. 76.5%) (p = 0.402). Conclusion: In the present study, the association of QFT to our routine LTBI screening incremented INH treatment referral, but there was still a high incidence of post-transplant TB, possibly related to other forms of infection, such as new exposure and donor transmission.
