Proteïna C-Reactiva com a marcador biològic de Dehiscència d’Anastomosi en Cirurgia Colo-rectal electiva

Estudi prospectiu de 208 pacients intervinguts de Cirurgia Colo-Rectal electiva amb anastomosi. L’objectiu és avaluar el valor de la monitorització de la Proteïna C-Reactiva (PCR) com a marcador biològic precoç de Dehiscència d’Anastomosi. La disminució de la PCR entre el segon i el cinquè dia del postoperatori de més del 39% té un valor predictiu negatiu del 97%, pel què pensem que hauria de ser una eina a tenir en compte en un protocol de fast-track. La PCR ha demostrat ser un paràmetre més fiable que els paràmetres de resposta inflamatòria sistèmica (recompte leucocitari, freqüència cardíaca, freqüència respiratòria i temperatura).

EURECCA colorectal: multidisciplinary mission statement on better care for patients with colon and rectal cancer in Europe

Background: Care for patients with colon and rectal cancer has improved in the last twenty years however still considerable variation exists in cancer management and outcome between European countries. Therefore, EURECCA, which is the acronym of European Registration of cancer care, is aiming at defining core treatment strategies and developing a European audit structure in order to improve the quality of care for all patients with colon and rectal cancer. In December 2012 the first multidisciplinary consensus conference about colon and rectum was held looking for multidisciplinary consensus. The expert panel consisted of representatives of European scientific organisations involved in cancer care of patients with colon and rectal cancer and representatives of national colorectal registries. Methods: The expert panel had delegates of the European Society of Surgical Oncology (ESSO), European Society for Radiotherapy & Oncology (ESTRO), European Society of Pathology (ESP), European Society for Medical Oncology (ESMO), European Society of Radiology (ESR), European Society of Coloproctology (ESCP), European CanCer Organisation (ECCO), European Oncology Nursing Society (EONS) and the European Colorectal Cancer Patient Organisation (EuropaColon), as well as delegates from national registries or audits. Experts commented and voted on the two web-based online voting rounds before the meeting (between 4th and 25th October and between the 20th November and 3rd December 2012) as well as one online round after the meeting (4th20th March 2013) and were invited to lecture on the subjects during the meeting (13th15th December 2012). The sentences in the consensus document were available during the meeting and a televoting round during the conference by all participants was performed. All sentences that were voted on are available on the EURECCA website www.canceraudit.eu. The consensus document was divided in sections describing evidence based algorithms of diagnostics, pathology, surgery, medical oncology, radiotherapy, and follow-up where applicable for treatment of colon cancer, rectal cancer and stage IV separately. Consensus was achieved using the Delphi method. Results: The total number of the voted sentences was 465. All chapters were voted on by at least 75% of the experts. Of the 465 sentences, 84% achieved large consensus, 6% achieved moderate consensus, and 7% resulted in minimum consensus. Only 3% was disagreed by more than 50% of the members. Conclusions: It is feasible to achieve European Consensus on key diagnostic and treatment issues using the Delphi method. This consensus embodies the expertise of professionals from all disciplines involved in the care for patients with colon and rectal cancer. Diagnostic and treatment algorithms were developed to implement the current evidence and to define core treatment guidance for multidisciplinary team management of colon and rectal cancer throughout Europe.

Ús de la ressonància magnètica nuclear amb espectroscopia per a la detecció del càncer prostàtic a la glàndula central

El diagnòstic precoç del càncer de pròstata fins a dia d’avui s’ha servit del tacte rectal, i els valors de PSA per establir quins pacients són sospitosos de patir aquesta afecció. Treballs recents estableixen que proves morfològiques com la ressonància magnètica, i funcionals com l’espectroscòpia ajudarien encara més a discriminar aquests pacients dels sans. En el nostre treball pretenem esbrinar; si l’ús de la ressonància magnètica amb espectroscòpia és igual d’eficient en el cas de que l’eventual càncer es localitzi a la glàndula central.

Pacients amb carcinoma de recte i cirurgia electiva, que s'els va realitzar una IH. Es van incloure 49 pacients, 32,7% van desenvolupar un AP. L'anàlisi univariant l'edat, el consum de tabac, MPOC, la IH de necessitat i el tancament del monyó rectal amb sutura manual, van ser factors de risc per al seu desenvolupament. L'anàlisi multivariant, el consum de tabac i la sutura manual van ser factors de risc.

Implantación de la cirugía laparoscópica en el cáncer de recto

Objectius: establir la viabilitat de la laparoscòpia en càncer rectal, morbi-mortalitat, resultats postoperatoris i seguretat oncològica respecte a la cirurgia oberta. Material i mètodes: recollim consecutivament, pacients intervinguts per càncer de recte i valorem; dades demogràfiques, condicions prèvies, resultats intra, postoperatoris i anatomopatològics. Resultats: sols trobarem diferències importants en el temps quirúrgic i ili paralític, que no foren estadísticament significatives. Si ho foren en estància hospitalària, a favor de la laparoscòpia. Es reconvertiren 3 pacients. Discussió: la laparoscòpia en càncer rectal ofereix resultats similars a la cirurgia oberta, amb algunes avantatges. Son necessaris més estudis per valorar la seguretat a llarg termini.

Colitis ulcerosa con afectación periapendicular. Estudio de casos y controles

La colitis ulcerosa (CU) es caracteritza per una afectació contínua de la mucosa rectal en sentit proximal cap a altres zones del còlon. Hi ha formes de CU amb afectació distal i periapendicular (CU-PA). Objectius: avaluar la prevalença de la CU-PA, i comparar les seves característiques clíniques, terapèutiques i evolutives. Mètodes: 14 pacients amb CU-PA van ser comparats en termes d'evolució clínica amb 25 pacients amb CU distal sense afectació periapendicular. Resultats: Es va trobar una major freqüència de CU-PA en homes (p = 0,047), sense diferències en la resta de les variables comparades entre els dos grups de pacients.

Clinical picture of the amyloid arthropathy in patients with chronic renal failure maintained on haemodialysis using cellulose membranes.

The clinical picture of 15 patients (10 male, five female) with amyloid arthropathy secondary to chronic renal failure treated with haemodialysis has been studied. The average period of haemodialysis was 10.8 years. Joint symptoms appeared between three and 13 years after starting haemodialysis. No patient had renal amyloidosis. Early symptoms were varied and often overlapped: knee swelling (seven patients), painful and stiff shoulders (seven), and carpal tunnel syndrome (six) were the most prominent. Follow up showed extension to other joints. Joint effusions were generally of the non-inflammatory type. Radiologically, geodes and erosions of variable sizes were seen in the affected joints, which can develop into a destructive arthropathy. Amyloid was found in abdominal fat in three of the 12 patients on whom a needle aspiration was performed. Four of 12 patients showed changes compatible with amyloid infiltration in the echocardiogram. One patient had amyloid in the gastric muscular layer, another in the colon mucus, and two of four in rectal biopsy specimens. Amyloid deposits showed the presence of beta 2 microglobulin in 10 patients. The clinical and radiological picture was similar to the amyloid arthropathy associated with multiple myeloma. These patients can develop systemic amyloidosis.

Posterior vaginal wall repair with synthetic absorbable mesh: A new technique for and old procedure

The objective of this study was to assess the applicability of posterior wall repair with a synthetic absorbable mesh. Between January and September 1996, five posterior repairs using absorbable synthetic meshes were performed. Five posterior wall repairs in patients matched for age, parity, and rectocele degree were performed according to usual procedures during the same period, and were used as controls. No febrile morbidity, cuff or posterior vaginal wall infections, thrombophlebitis, rectal injury, or hemorrhagic complications were observed in the 10 women who entered the study. In summary, posterior wall repair can be easily performed with an absorbable soft tissue patch, theoretically preserving sexual activity, and probably offers better functional results with longer experience, thus providing a safe and useful procedure in sexually active women.

Oncobiguanides: Paracelsus" law and nonconventional routes for administering diabetobiguanides for cancer treatment

The dose makes the poison, the common motto of toxicology first expressed by Paracelsus more than 400 years ago, may effectively serve to guide potential applications for metformin and related biguanides in oncology. While Paracelsus' law for the dose-response effect has been commonly exploited for the use of some anti-cancer drugs at lower doses in non-neoplastic diseases (e.g., methotrexate), the opposite scenario also holds true; in other words, higher doses of non-oncology drugs, such as anti-diabetic biguanides, might exert direct anti-neoplastic effects. Here, we propose that, as for any drug, there is a dose range for biguanides that is without any effect, one corresponding to"diabetobiguanides" with a pharmacological effect (e.g., insulin sensitization in type 2 diabetes, prevention of insulin-dependent carcinogenesis, indirect inhibition of insulin and growth factor-dependent cancer growth) but with minimal toxicity and another corresponding to 'oncobiguanides' with pharmacological (i.e., direct and strong anticancer activity against cancer cells) as well as toxic effects. Considering that biguanides demonstrate a better safety profile than most oncology drugs in current use, we should contemplate the possibility of administering biguanides through non-conventional routes (e.g., inhaled for carcinomas of the lung, topical for skin cancers, intravenous as an adjunctive therapy, rectal suppositories for rectal cancer) to unambiguously investigate the therapeutic value of high-dose transient biguanide exposure in cancer. Perhaps then, the oncobiguanides, as we call them here, could be viewed as a mechanistically different type of anti-cancer drugs employed at doses notably higher than those used chronically when functioning as diabetobiguanides
