RESUMEN
La miocardiopatía periparto es una enfermedad poco frecuente de causa desconocida, que se caracteriza por la aparición de insuficiencia cardíaca aguda en embarazadas que cursan el último mes de gestación y en el puerperio. En las poblaciones estudiadas, la frecuencia más alta se observa en Haití, donde se estima 1 caso cada 299 nacidos vivos; Sudáfrica 1 caso cada 1000 nacidos vivos. Las frecuencias más bajas corresponden a los Estados Unidos (1 caso cada 4000 nacidos vivos) y Europa. La tasa de mortalidad hospitalaria estimada es del 1,36% y la tasa global de mortalidad, del 2,05%. Se desconoce su verdadera prevalencia e incidencia en la Argentina, probablemente como consecuencia de subregistros. En nuestra Unidad de Terapia Intensiva Obsté- trica, ingresaron dos casos de miocardiopatía periparto, en un período de dos años, que fueron abordados por el equipo multidisciplinario compuesto por intensivistas, cardiólogos, nefrólogos y obstetras.(AU)
Peripartum cardiomyopathy is an unusual condition of unknown origin that is characterized by an acute heart failure during the last months of pregnancy and the puerperium. Most case studies show that Haiti has the highest rate of peripartum cardiomyopathy, 1 in 299 live births, followed by South Africa with 1 in 1,000 and the lowest rate is observed in United States (1 in 4,000 live births) and Europe. Hospital case mortality rate is 1.36% with a global mortality rate of 2.05%. Its prevalence and incidence in Argentina are unknown, perhaps as a result of underreporting cases. Two cases of peripartum cardiomyopathy were treated in our Obstetric Intensive Care Unit within a period of two years by a multidisciplinary team of intensivists, cardiologists, nephrologists and obstetricians.(AU)

INTRODUCTION: Endoscopic ultrasonography (EUS)-guided fine-needle aspiration (FNA) have a better accuracy for the detection of pancreatic tumors compared with others images modalities. We assessed if the image criteria of elastography and contrast harmonic echo-endoscopic ultrasound could help in choosing the appropriate FNA-needle in the evaluation of focal pancreatic mass in other to maximize the diagnostic yield. This study prospectively included all new patients with focal pancreatic masses referred to be examined by EUS from October to December/2013. A total of 21 patients performed EUS with sequentially elastography and intravenous injection of a second-generation contrast agent (2.4 mL of SonoVue, Braco International, The Netherlands). The lesions which appear hipovascular were assessed with 22 gauge or 25 gauge FNA-needles. The hipervascular masses were biopsied with 19 gauge needles. RESULTS: The topography of the lesions varied on 13 at the head, 4 at the body and 1 on the tail. The finding of a hypoenhanced mass was found in 57% (12/21 patients). Hyperenhanced was detected in 28% (6/21 patients). There were 14% (three patients) which the data were not recorded. The cytological diagnosis was achieved in 81% (17/21 patients) on the first biopsy. The others four patients have reached the diagnosis on the second examination. Of those four patients, in one was used the ProCore 25 gauge (lesion on the uncinatus process), and another one was used both 22 gauge and 25 gauge in the first examination. CONCLUSION: A characterization of the pancreatic lesions with elastography and contrast agents might be useful for clinical decision of which needle is better to improve biopsy quality and minimize EUS-FNA negatives results.
RESUMEN
OBJECTIVE: Endoscopic ultrasound (EUS) is established as the most accurate technique for pre-operative locoregional staging of gastroesophageal junction (GEJ) adenocarcinoma, the purpose of the present study was to evaluate the distant lymph nodes (LNs) EUS-fine-needle aspiration (FNA) impact in therapeutic decision for patients with GEJ adenocarcinoma. MATERIALS AND METHODS: Retrospective study was made, with cross-sectional, non-probabilistic analysis from prospectively collected database for all GEJ adenocarcinoma staging patients referred between January 2009 and August 2012 in Paoli-Calmette Institute in Marseille-France. RESULTS: A total of 154 patients with GEJ adenocarcinoma were managed in our institution, of whom 113 (73.3%) had non-distant metastatic disease at computed tomography (CT) scan and underwent EUS for initial tumor staging prior to a treatment decision. On A total of 113 patients undergoing EUS, 8 (7%) patients underwent endoscopic resection and 6 (5.3%) underwent direct surgical resection. Of the remaining 99 patients (87.6%), 24 (21.2%) distant LN EUS-FNA were made. Seventeen LN had EUS malignant features, including 9 (52.9%) that were confirmed as malignant and underwent palliative treatment with chemotherapy. Ninety (79.6%) patients were treated with pre-operative neoadjuvant therapy and were revaluated after. 4 (4.4%) had metastatic disease at CT scan (underwent palliative treatment) and 65 (72.2%) underwent EUS restaging to treatment decision revaluation. Of these, twelve (18.4%) distant LN EUS-FNA were performed. Seven had LN EUS malignancy features, including 4 (57.1%) that were confirmed as malignant and underwent palliative treatment. The remaining 61 patients underwent surgery. As stated above, 21 patients (23.3%) did not undergo EUS restaging, including 10 (47.6%) that did not go to surgery because patient's age, poor general status and comorbidities, 6 (28.5%) had a loss of follow-up, 1 (4.7%) underwent to surgery due to chemotherapy collateral effects, 3 (14.2%) were still on pre-operative chemotherapy and 1 (4.7%) died for sepsis after mediastinal EUS-FNA, this was the only complication event evidenced. EUS-FNA changed clinical management in 54.2% of patients who met the criteria inclusion (distant LN with malignancies EUS features), which corresponds to 11.5% of patients with GEJ adenocarcinoma. CONCLUSION: EUS-FNA was able to provide a different tumor staging and these differences were associated with treatment received. EUS-FNA had a significant impact on treatment decision.
RESUMEN
Epitheliomesenchymal biphasic neoplasms are extremely rare in the duodenum, and most of these are carcinosarcomas. Miettinen et al. (Am J Surg Pathol 33:1370-7, 2009) recently reported three cases of a novel distinctive epitheliomesenchymal biphasic tumor of the stomach in young adults. In view of the resemblance to other childhood blastomas, they proposed to refer to this entity as a gastroblastoma. Since none of the components were sufficiently atypical, the gastroblastoma seemed more comparable to this kind of tumor than carcinosarcomas or other aggressive and malignant biphasic tumors. This report describes a duodenal location of a similar epitheliomesenchymal biphasic tumor in a 22-year-old woman. To our knowledge, this is the first reported case occurring primarily in the duodenum and might be the first case of "duodenoblastoma."

UNLABELLED: Endoscopic resection (EMR) and radiofrequency ablation (RFA) form part of the treatment of Barrett's oesophagus (BO), dysplasia, superficial adenocarcinoma (OAC) associated with BO. PATIENTS AND METHODS: Between June 2008 and April 2011, 34 patients underwent treatment with RFA (HALO system(®)), in a tertiary centre. For the study, patients were divided into two groups. Group 1 (16 patients of average 60 years old; 14 men, two women) received EMR and RFA. Group 2 (18 patients averaging 59 years age; 14 men, four women) received RFA without EMR in the year preceding the RFA. RESULTS: In group 1, high grade dysplasia (HGD) was eradicated in 12 cases (92%), low grade dysplasia (LGD) in three cases (100%). Complete response occurred in nine cases (56%), partial response in 100% of cases. Mean follow-up was 15 months. In group 2, HGD was eradicated in one patient (100%), LGD in three patients (64%). A complete response was achieved in eight patients, partial response in four cases (77%). Mean follow-up was 10 months. The complication rate for groups 1 and 2 was of 18% and 10% respectively. No complication prevented completion of treatment or continued monitoring. Recurrence was evaluated to 5% in both groups. CONCLUSION: RFA associated with EMR is feasible, offering probably better results and a very important advantage: a more complete histology before follow-up. Our results show effective treatment of BO and associated dysplasia with a low rate of complication. Nevertheless, when new techniques of BO ablation are used, the need to obtain histology before treatment should not be forgotten.

Gastrointestinal stromal tumors (GISTs) are the most common human sarcoma. Most of the data available on GISTs derive from retrospective studies of patients referred to oncology centers. The MolecGIST study sought to determine and correlate clinicopathological and molecular characteristics of GISTs. Tumor samples and clinical records were prospectively obtained and reviewed for patients diagnosed in France during a 24-month period. Five hundred and ninety-six patients were included, of whom 10% had synchronous metastases. GISTs originated from the stomach, small bowel or other site in 56.4, 30.2 and 13.4% of cases, respectively. The main prognostic markers, tumor localization, size and mitotic index were not independent variables (P < 0.0001). Mutational status was determined in 492 (83%) patients, and 138 different mutations were identified. KIT and PDGFRA mutations were detected in 348 (71%) and 74 (15%) patients, respectively, contrasting with 82.8 and 2.1% in patients with advanced GIST (MetaGIST) (P < 0.0001). Further comparison of localized GISTs in the MolecGIST cohort with advanced GISTs from previous clinical trials showed that the mutations of PDGFRA exon18 (D842V and others) as well as KIT exon11 substitutions (W557R and V559D) were more likely to be seen in patients with localized GISTs (odds ratio 7.9, 3.1, 2.7 and 2.5, respectively), while KIT exon 9 502_503dup and KIT exon 11 557_559del were more frequent in metastatic GISTs (odds ratio of 0.3 and 0.5, respectively). These data suggest that KIT and PDGFRA mutations and standardized mitotic count deserve to be investigated to evaluate the relapse risk of GISTs.

PURPOSE: Neoadjuvant chemoradiation followed by surgery is the standard of care for locally advanced rectal cancer. The aim of this study was to correlate tumour response to survival and to identify predictive factors for tumour response after chemoradiation. PATIENTS AND METHODS: From 1998 to 2008, 168 patients with histologically-proven locally advanced adenocarcinoma treated by preoperative chemoradiation before total mesorectal excision were retrospectively studied. They received a radiation dose of 45 Gy with a concomitant 5-fluoro-uracil-based chemotherapy. Analysis of tumour response was based on the lowering of T stage between pre-treatment endorectal ultrasound and pathologic specimens. Overall and progression-free survival was correlated with tumour response. Tumour response was analysed with predictive factors. RESULTS: The median follow-up was 34 months. Five-year disease-free survival and overall survival were respectively of 44.4% and 74.5% in the whole population, 83.4% and 83.4% in patients with pathological complete response, 38.6% and 71.9% in patients with tumour downstaging, 29.1% and 58.9% in patients with absence of response. A pre-treatment concentration of carcinoembryonnic antigen below 5 ng/mL was significantly associated with tumour downstaging and significantly independently associated with pathologic complete tumour response (P = 0.019). CONCLUSION: Downstaging and complete response after chemoradiation improved progression-free survival and overall survival of locally advanced rectal adenocarcinoma. In multivariate analysis, a pre-treatment concentration of carcinoembryonnic antigen below 5 ng/mL was associated with complete tumour response, hence with tumour downstaging.

BACKGROUND: Confocal endomicroscopy is an emergent technique and allows real optical biopsies in the gastrointestinal (GI) tract. The aim of this study was to evaluate a new intraductal confocal miniprobe in patients with a normal common bile duct (CBD) or with a suspicion of a malignant stenosis (cholangiocarcinoma). METHODS: Thirty-seven patients (23 males) underwent endoscopic retrograde cholangiopancreatography (ERCP) for bile duct stone removal (7 cases) or bile duct stenosis (30 cases). Intraductal confocal microscopy (IDCM) was performed during the ERCP using a probe-based confocal laser endomicroscopy (pCLE) technique. IDCM was done with the CholangioFlex probe with Cellvizio (Mauna Kea Technologies, Paris, France). The depth of penetration of theCholangioFlex probe was 40-70 µm and magnification was 400×. Images were reviewed by an experienced pathologist in GI disease and compared to ERCP findings, CBD biopsies performed during ERCP or EUS, and in 15 patients to the resected specimen (Wipple resection). RESULTS: No complications related to the CholangioFlex insertion occurred after the ERCP. Good images were obtained in 33 patients. Final histology diagnosis was a normal CBD in 7 cases, 23 malignant stenoses (4 ampullary carcinomas, 13 cholangiocarcinomas, and 6 pancreatic cancer), and 7 inflammatory stenoses (4 chronic pancreatitis, 1 stenosis of hepaticojejunal anastomosis, 1 postcholecystectomy CBD stenosis, and 1 primary sclerosing cholangitis). IDCM of a normal CBD showed a thin black band (<20 µm), normal vessels (thin and regular), and no visible glands. IDCM of malignant strictures revealed irregular vessels with lack of contrast in the CBD wall, large black band (>20 µm), and an aggregate of irregular black cells (black clumps). These aspects were seen in all malignant stenoses and none were seen in benign or normal CBD. The presence of irregular vessels, large black bands, and black clumps seen with confocal laser microscopy enabled prediction of neoplasia with an accuracy rate of 86%, sensitivity of 83%, and specificity of 75%. The respective numbers for standard histopathology were 53, 65, and 53%. CONCLUSION: This phase I-II study on IDCM showed that IDCM is feasible. This new technique will open a new door for optical biopsy of the CBD.

BACKGROUND: This study retrospectively describes the outcome of a series of 38 patients (pts) with T4 anal carcinoma exclusively treated by radio and chemotherapy. PATIENTS AND METHODS: From 1992 to 2007, 38 pts with UST4-N0-2-M0 anal carcinoma were treated with exclusive radiotherapy and chemotherapy. All patients received external beam radiotherapy (EBRT) (median dose 45 Gy) with a concomitant chemotherapy (5-fluorouracil-cisplatin). Eleven patients received neo-adjuvant chemotherapy (5-fluorouracil-cisplatin). After 2-8 weeks, a 15-20 Gy boost was delivered either with EBRT (20 pts) or interstitial (192)Ir brachytherapy (18 pts). Mean follow-up was 66 months. RESULTS: After chemoradiation therapy (CRT), 13 pts (34%) had a complete response, 23 pts (60%) a response >50% (2 pts were not evaluated). The 5-year-disease-free survival was 79.2 ± 6.5%, and the 5-year overall survival was 83.9 ± 6%. Eight patients developed tumor progression (mean delay 8.8 months), six of them requiring a salvage surgery with definitive colostomy for local relapse. Late severe complication requiring colostomy was observed in 2 pts. The 5-year-colostomy-free survival was 78 ± 6.9%. Patients who received primary chemotherapy had a statistically significant better 5-year colostomy-free survival (100% vs. 38 ± 16.4%, P = 0.0006). CONCLUSION: T4 anal carcinoma can be treated with a curative intent using a sphincter-sparing approach of CRT, and neo-adjuvant chemotherapy should be considered prior to radiotherapy.

Multicystic peritoneal mesothelioma is a rare lesion occurring mainly in women in a reproductive age. Its pathogenesis is unclear. We report three cases of multicystic peritoneal mesothelioma in patients that were 28, 38 and 47 years of age (one male, two females). A history of abdominal surgery was reported in two cases. Explorative laparotomy was presumptive of a pseudomyxoma peritoni in two cases, and hyperthermic intraperitoneal chemotherapy was performed. Histological examination demonstrated multicystic lesions with mesothelial cells lining confirmed by immunohistochemical analysis. Unusual findings such as hyperplasia, hobnail features, cytoplasmic vacuolisation and papillary pattern were occasionally noted. The clinical presentation, pathogenesis and pathologic features including differential diagnosis of multicystic peritoneal mesothelioma are discussed.

BACKGROUND: Barrett's esophagus-related high-grade dysplasia or mucosal cancer can be treated by endoscopic mucosal resection (EMR), but the adjacent metaplastic epithelium remains at risk for developing further lesions. Our objective was to evaluate the results of the circumferential EMR in removing not only the neoplastic lesion but also the remaining Barrett's epithelium. METHODS: Forty-one consecutive patients (mean age: 66 years) with Barrett's esophagus were submitted to 63 EMR sessions in one single-referral endoscopic unit. All patients had high-grade dysplasia, and cancer was detected in 23 of these cases, most of them classified as T1N0 (20 patients) by endosonography. Mucosectomy after saline submucosal injection was performed for the neoplastic lesions and, if necessary, the residual Barrett's epithelium was removed by the same technique one month later. RESULTS: A retrospective evaluation showed that, during a mean follow-up of 31.6 months, Barrett's epithelium was completely replaced by squamous epithelium in 31 (75.6%) cases. There were 10 complications, all of which were managed endoscopically: 8 cases of bleeding and two perforations occurred in 9 (14.3%) patients. One patient developed an esophageal stricture. Barrett's epithelium recurred in 10 (24.4%) patients and recurrent or metachronous early cancer was detected in 5 (12.2%), all but one of which were treated again by EMR; the fifth patient was referred to surgery. Argon plasma coagulation was used in 6 cases to treat Barrett's epithelium, and two patients received concomitant chemoradiotherapy as adjuvant therapy. CONCLUSIONS: Circumferential EMR provides an effective endoscopic approach to the management of Barrett's esophagus-related high-grade dysplasia and mucosal cancer. Additional studies are necessary to evaluate the long-term results.

BACKGROUND AND STUDY AIMS: It is well known that some diseases, such as cancer, lead to changes in the hardness of tissue. Sonoelastography, a technique that allows the elasticity of tissue to be assessed during ultrasound examination, provides the ultrasonographer with important additional information that can be used for diagnosis. The aim of this study was to evaluate the ability of endoscopic ultrasound elastography to differentiate between benign and malignant pancreatic masses and lymph nodes. PATIENTS AND METHODS: During a 12-month period, 49 patients underwent endoscopic ultrasound (EUS) examinations with elastography, conducted by a single endoscopist. Twenty-four patients underwent evaluation of a pancreatic mass (mean diameter 24.7 +/- 11.1 mm) and 25 underwent evaluation of 31 lymph nodes. The mean diameter of the lymph nodes was 19.7 +/- 8.6 mm, and they were found in the cervical area (n = 3), mediastinum (n = 17), celiac arterial trunk region (n = 5), and aortocaval region (n = 6). RESULTS: The sonoelastography images of pancreatic masses were interpreted as benign in four cases and malignant in 20. The sensitivity and specificity of sonoelastography in the diagnosis of malignant lesions were 100% and 67%, respectively. The sonoelastography images of the lymph nodes were interpreted as showing malignancy in 22 cases, benign conditions in seven, and indeterminate status in two. The sensitivity and specificity of sonoelastography for evaluating malignant lymph-node invasion were 100% and 50%, respectively. CONCLUSIONS: EUS elastography is potentially capable of further defining the tissue characteristics of benign and malignant lesions but specifity has to be improved. It can be used to guide biopsy sampling for diagnosis.

BACKGROUND AND STUDY AIMS: The aim of this study was to evaluate the efficacy and outcomes of treatment by endoscopic mucosal resection (EMR) of patients with high-grade dysplasia (HGD) or carcinoma. PATIENTS AND METHODS: Between January 1995 and January 2002, 50 patients (35 men, 15 women) were treated by EMR for 52 sessile polyps. The median size of the polyps was 27.5 mm (range 10-60). The "lift and cut" EMR technique was used. If the lesion was poorly differentiated or infiltrated the muscularis mucosae to more than 1000 microm, the patient was referred for colectomy. In the other cases, follow-up was proposed. RESULTS: Complications occurred in 9.6 % of cases and were always treated conservatively. The rate of endoscopically complete resection was judged to be 98.1 %. Argon plasma coagulation was applied to the margins of the lesion in 21.6 % of cases. Histological examination showed 38 HGDs and 14 carcinomas. Seven patients had a lesion reaching the deep or lateral margin; four were referred for surgery; two patients for whom surgery would have been high risk were followed up, and both developed local recurrence; and one patient was followed up, without recurrence, because infiltration was less than 1000 microm. A total of 43 patients were followed up after complete excision. Two patients died during follow-up; neither death could be reliably attributed to colorectal carcinoma. Seven patients were lost during the follow-up. For 34 patients, information from a mean follow-up of 17.3 months (6 - 57) was available and recurrence was observed in five cases (15 %). CONCLUSIONS: EMR appears to be a safe and efficient treatment of HGD and early colorectal cancer. However, correct analysis of submucosal infiltration is essential to assess the completeness of the resection.

BACKGROUND: Although experience of laparoscopic treatment of rectal carcinoma has been reported, there is no evidence of its oncological safety because most procedures included partial mesorectal excision or abdominoperineal excision and quality of surgery is lacking. The aim of this study was to assess the oncological results of laparoscopic total mesorectal excision with sphincter preservation for rectal carcinoma. METHODS: From 2000 to 2003, 144 patients underwent laparoscopic total mesorectal excision with low colorectal or coloanal anastomosis for mid and low rectal adenocarcinoma. There were 88 men and 56 women, with a median age of 65 years. The tumor was located at 5.5 cm (range 1-12) from the anal verge and was classified uT1T2 in 25 cases and uT3 in 119 cases. One hundred twenty patients received preoperative radiotherapy. RESULTS: Postoperative mortality and morbidity were 1% and 34% respectively. Conversion was 14% (n = 20). Macroscopic assessment of the specimen (n = 92) showed an intact mesorectum in 88% of the cases. The distal margin and the circumferential margin were safe in 98% and 94% of the cases, respectively. A complete microscopic excision, i.e., R0 resection, was achieved in 134 cases (93%). Pathological data were similar to those of an open match group. With a median follow-up of 18 months, there was no port-site recurrence and two patients had local recurrence (1.4%). The 3-year overall and disease- free survival rates were 89% and 77%, respectively. CONCLUSIONS: A high quality of surgical excision can be achieved by the laparoscopic dissection, suggesting that this approach in treatment of rectal carcinoma is oncologically safe.

CONTEXT: "The Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the Federation of French Cancer Centers (FNCLCC), the 20 French regional cancer centers, and specialists from French Public Universities, General Hospitals and Private Clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. OBJECTIVES: To elaborate clinical practice guidelines for patients with stomach adenocarcinoma. These recommendations cover the diagnosis, treatment and follow-up of these tumors. METHODS: The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. The Standards, Options and Recommendations are thus based on the best available evidence and expert agreement. RESULTS: Adjuvant radiation therapy alone is not a standard treatment for patients with stomach adenocarcinoma. Adjuvant concomitant chemoradiotherapy is not a standard treatment for patients with stage II or III stomach adenocarcinoma R0, with Dl or D2 lymphadenectomy who have undergone surgery. Following surgical resection, adjuvant concomitant chemoradiotherapy should be proposed to patients without denutrition with a lymphadenectomy < Dl (fewer than 15 lymph nodes examined) and those with T3 and/or N+ tumours following the protocol used in the MacDonald trials (SWOG-9008) (Level of evidence B1). Adjuvant concomitant chemoradiotherapy can be administered to patients without denutrition with DI or D2 lymphadenectomy and with involvement of regional lymph nodes (N2 or N3).

Gastric duplication cyst (GDC) in an adult can have several clinical presentations. A review of the literature showed previously reported cases of GDC presenting as pancreatic pseudocyst or with greatly raised concentrations of carbohydrate antigen 19-9 (CA 19-9). It is often difficult to discriminate GDC from pancreatic cystic tumour, in particular pancreatic mucinous cystadenoma, in which concentrations of carcinoembryonic antigen and CA 19-9 are classically raised. This report describes an adult case of GDC mimicking a mucinous cystadenoma of the pancreas. This is the first report of a simultaneous increase in carcinoembryonic antigen and CA 19-9 in GDC in the absence of malignancy. Although few cases of carcinoma arising from a GDC having been reported, the production of oncofetal antigens raises the problem of a precancerous condition in long standing intestinal duplications. In this situation surgical resection must be performed.
