[Jejunal intestinal metastases, a form of presentation of pulmonary carcinoma]. / Metástasis intestinales yeyunales, forma de presentación de un carcinoma pulmonar.

Primary tumors of the small intestine are rare, and metastatic ones are even rarer. It is exceptional for small bowel metastases to manifest before the primary tumor. The clinical presentation may require surgical resection motivated by intestinal perforation, hemorrhage or intestinal obstruction-subocclusion. Survival is scarce and generally does not exceed 20 weeks, regardless of the treatment performed.

Metástasis intestinales yeyunales, forma de presentación de un carcinoma pulmonar / Jejunal intestinal metastases, a form of presentation of pulmonary carcinoma

Los tumores primarios de intestino delgado son muy infrecuentes, siendo todavía más raros los metastásicos. Es excepcional que las metástasis de intestino delgado se manifiesten antes que el tumor primario. La presentación clínica puede requerir una resección quirúrgica intestinal motivada por perforación, hemorragia, obstrucción-suboclusión intestinal e incluso invaginación intestinal. La supervivencia, es escasa y generalmente no supera las 20 semanas, independientemente del tratamiento que se realice (AU)

SEMICYUC 2012. Recommendations for intensive care management of acute pancreatitis.

OBJECTIVE: Significant changes in the management of acute pancreatitis have taken place since the 2004 Pamplona Consensus Conference. The objective of this conference has been the revision and updating of the Conference recommendations, in order to unify the integral management of potentially severe acute pancreatitis in an ICU. PARTICIPANTS: Spanish and international intensive medicine physicians, radiologists, surgeons, gastroenterologists, emergency care physicians and other physicians involved in the treatment of acute pancreatitis. LEVELS OF EVIDENCE AND GRADES OF RECOMMENDATION: The GRADE method has been used for drawing them up. DRAWING UP THE RECOMMENDATIONS: The selection of the committee members was performed by means of a public announcement. The bibliography has been revised from 2004 to the present day and 16 blocks of questions on acute pancreatitis in a ICU have been drawn up. Firstly, all the questions according to groups have been drawn up in order to prepare one document. This document has been debated and agreed upon by computer at the SEMICYUC Congress and lastly at the Consensus Conference which was held with the sole objective of drawing up these recommendations. CONCLUSIONS: Eighty two recommendations for acute pancreatitis management in an ICU have been presented. Of these 84 recommendations, we would emphasize the new determinants-based classification of acute pancreatitis severity, new surgical techniques and nutritional recommendations. Note. This summary only lists the 84 recommendations of the 16 questions blocks except blocks greater relevance and impact of its novelty or because they modify the current management.

[Clinical pathways in acute pancreatitis: recommendations for early multidisciplinary management. Scientific Committee of the SEMICYUC. Working Group on Infectious Diseases (GTEI-SEMICYUC)]. / Hoja de ruta de los cuidados clínicos para la pancreatitis aguda: recomendaciones para el manejo anticipado multidisciplinar (clinical pathways).

There is a growing body of evidence that early management of patients with acute pancreatitis may alter the natural course of disease and improve outcomes of patients. The aim of this paper is to optimize the management of patients with acute pancreatitis during the first 72 h after hospital admission by proposing several clinical care pathways. The proposed pathways are based on the SEMICYUC 2005 Recommendations with incorporation of the latest developments in the field, particularly the determinants-based classification of acute pancreatitis severity. The pathways also incorporate the "alarm signs", the use of therapeutic modalities known as PANCREAS, and the "call to ICU" criteria. Further studies will need to assess whether the adoption of these pathway reduces mortality and morbidity in patients with acute pancreatitis. The previous SEMICYUC guidelines on management of patients with acute pancreatitis in Intensive Care will need to be revised to reflect the recent developments in the field.

Intestinal metaplasia: evolution after Helicobacter pylori eradication and influence in the success of eradicating therapy.

INTRODUCTION: intestinal metaplasia associated with Helicobacter pylori infection is a stage of the temporal sequence of histological lesions gradually induced by this microorganism. It is considered a preneoplastic lesion and its regression after eradication is controversial. AIM: to assess the evolution of intestinal metaplasia after eradication and to investigate whether metaplasia is a factor that contributes to successful treatment. MATERIAL AND METHODS: four hundred Helicobacter pylori positive patients were studied. Eradicating therapy was administered and endoscopic biopsies of gastric antrum and body were taken before and after eradication. Among other histological data, the presence of intestinal metaplasia was assessed. RESULTS: of all patients successfully treated, biopsies were taken before and after eradication in 268 of them: 71 (26,5%) had metaplasia before and 50 (18,7%) after eradication. A significant difference was observed in the outcome (p = 0,036) of the first eradicating treatment between the group without initial metaplasia (72,7%) and the group with initial metaplasia (61.2%). DISCUSSION: Helicobacter pylori eradication can revert intestinal metaplasia in some patients. On the other hand, the first treatment could be less successful in patients with intestinal metaplasia.

Use of combined treatment of hepatitis B immune globulin and lamivudine as prevention of hepatitis B virus recurrence in liver allograft.

Antiviral prophylaxis with lamivudine appears to reduce hepatitis B virus (HBV) infection after liver transplantation, although recurrence of infection occurs in at least 20% of the patients because of the development of drug resistance. Treatment for HBV reinfection with lamivudine pretransplantation and posttransplantation together with hepatitis B immunoglobulin could abolish recurrence of HBV infections following liver transplantation. We report the experience at our center in which lamivudine has been used in combination with low doses of immunoglobulin. Lamivudine (100 mg/d) was administered to liver transplant candidates for at least 4 weeks before transplantation and was continued posttransplantation indefinitely. Immunoglobulin was administered intramuscularly (10,000 IU at time of liver transplantation; 1,000 IU for 1 week; 1,000 IU weekly the first month; and 1,000 IU monthly thereafter). Lamivudine and low-dose immunoglobulin administration prevents posttransplantation recurrence of hepatitis B with 100% efficiency; it is well tolerated and is less cost-effective than high-dose immunoglobulin regimens.

Prophylaxis of recurrent hepatitis B virus by vaccination after liver transplant: preliminary results.

Liver transplantation for chronic HBV-induced cirrhosis is associated with a high rate of recurrence and poor long-term survival. Prolonged and combined prophylaxis with hepatitis B immunoglobulin (HBIg) and lamivudine has been demonstrated to prevent HBV recurrence, but its lifelong administration is highly expensive. An alternative strategy may be the use of an HBV vaccine after liver transplantation. Herein we report the results of administration of a reinforced recombinant HBV vaccine to liver transplant recipients. Twelve patients transplanted for HBV-related liver disease and treated with HBIg for at least 24 months were administered HBV vaccine (40 microg administered intramuscularly and repeated 1 and 2 months thereafter) 2 months after beginning the last HBIg dose. The response rate to HBV vaccination was 75% (9/12 patients). Serum titers of anti-HBs were considered to be protective when they reached levels >10 IU/L. Responding patients were followed for a median of 43+/-22.5 months; during this period none of the responders showed evidence of HBV recurrence. These results suggest that vaccine administration after liver transplant may avoid HBV recurrence allowing HBIg withdrawal. However, future studies are necessary to define an optimal schedule.

Fibrin-glue sealed liver biopsy in patients with a liver transplantation or in liver transplantation waiting list: preliminary results.

Liver biopsy is frequently necessary for candidate evaluation or histologic follow-up of transplanted livers. Although generally considered to be safe, it carries a risk of complications in up to 0.5% of cases; hemorrhage being the most important. It can present as an asymptomatic intra- or perihepatic hematoma or result in overt hemorrhage of variable intensity. Patients with deranged hemostasis or on antiaggregant therapy are at high-risk for hemorrhagic complications. Percutaneous liver biopsy may be contraindicated if hemostasis is profoundly disordered. Safety values are not well defined: arbitrary limits are 60% prothrombin activity and 60,000 platelets per mm3. Patients with more altered values are candidates for alternative techniques, such as transjugular biopsy. Another option is the so-called plugged percutaneous liver biopsy, which uses direct injection of a plugging material into the biopsy tract. Different materials have been used: Tissucol, absorbable gelatin sponge, or hemostasis coils. We communicate our experience with Tissucol (fibrin glue) plugging in 30 percutaneous liver biopsies on 16 patients after liver transplantation with prothrombin activity <60%, platelet count <60,000 per mm3, or both. Only two complications were observed. Plugged liver biopsy is an efficient and relatively safe procedure in patients with impaired hemostasis; it can be performed even when transjugular biopsy is not available.
