Incidence and distribution of coeliac disease in Campania (Italy): 2011-2013.

BACKGROUND: There exists a wide variation in the reported incidence of coeliac disease in recent decades. We aimed to evaluate the incidence rate of coeliac diagnoses performed in an Italian region, Campania, between 2011 and 2013 and its variation therein. METHODS: All coeliac diagnoses made from 2011 to 2013 and registered within the Campania coeliac disease register (CeliacDB) were identified. Incidence rates were analysed by sex, age and province of residence, with a Poisson model fitted to determine incidence rate ratios. RESULTS: We found 2049 coeliac disease diagnoses registered in the CeliacDB between 2011 and 2013; 1441 of these patients were female (70.4%) and 1059 were aged less than 19 years (51.7%). The overall incidence of coeliac disease in Campania was 11.8 per 100,000 person-years (95% CI 11.3-12.3) during the study period, with marked variation by age [27.4 per 100,000 person-years (95% CI 25.8-29.1) in children under 19 years of age and 7.3 per 100,000 (95% CI 6.8-7.8) in adults] and sex [16.1 per 100,000 person-years in females (95% CI 15.3-16.9) and 7.2 per 100,000 person-years in males (95% CI 6.6-7.8)]. Coeliac disease incidence was roughly similar in Naples, Salerno, Caserta and Avellino, but about half in Benevento. More than 80% of our study population was diagnosed by the combination of positive antitransglutaminase IgA and Marsh 3. More than half of the patients were symptomatic at the time of coeliac disease diagnosis (39.7% had a classical presentation and 21.1% a non-classical one according to the Oslo definition). CONCLUSIONS: Coeliac disease incidence was roughly similar among Campania provinces, except in Benevento where it was about half, probably due to less awareness of coeliac disease in this area. The incidence of coeliac disease in Campania appears to be lower than that reported by most of the previous literature, suggesting the necessity of new coeliac awareness programmes.

Trimodal endoscopic imaging for the detection and differentiation of colorectal adenomas: a prospective single-centre clinical evaluation.

PURPOSE: The purpose of this study is to evaluate an endoscopic trimodal imaging (ETMI) system (high resolution, autofluorescence, and NBI) in the detection and differentiation of colorectal adenomas. METHODS: A prospective randomised trial of tandem colonoscopies was carried out using the Olympus XCF-FH260AZI system. Each colonic segment was examined twice for lesions, once with HRE and once with AFI, in random order per patient. All detected lesions were assessed with NBI for pit pattern and with AFI for colour. All lesions were removed and sent for histology. Any lesion identified on the second examination was considered as missed by the first examination. Outcome measures are adenoma miss rates of AFI and HRE, and diagnostic accuracy of NBI and AFI for differentiating neoplastic from non-neoplastic lesions. RESULTS: Ninety-four patients underwent colonoscopy with ETMI (47 in each group). Among 47 patients examined with AFI first, 31 adenomas in 15 patients were detected initially [detection rate 0.66 (0.52-0.75)]. Subsequent HRE inspection identified six additional adenomas. Among 47 patients examined with HRE first, 29 adenomas in 14 patients were detected initially [detection rate 0.62 (0.53-0.79)]. Successive AFI yielded seven additional adenomas. Adenoma miss rates of AFI and HRE were 14% and 16.2%, respectively (p = 0.29). Accuracy of AFI alone for differentiation was lower than NBI (63% vs. 80%, p < 0.001). Combined use of AFI and NBI achieved improved accuracy for differentiation (84%), showing a trend for superiority compared with NBI alone (p = 0.064). CONCLUSIONS: AFI did not significantly reduce the adenoma miss rate compared with HRE. AFI alone had a disappointing accuracy for adenoma differentiation, which could be improved by combination of AFI and NBI.

Endocytoscopic classification of preneoplastic lesions in the colorectum.

PURPOSE: The aim of this study is to assess the capability of endocytoscopy (ECS) in differentiating neoplastic from nonneoplastic lesions in the colorectum and to validate an ECS classification. METHODS: Patients with colorectal polypoid and nonpolypoid lesions < or =10 mm were prospectively included. ECS classification subgrouped nonneoplastic (EC 0) and neoplastic (EC 1-3) lesions. Lesions were observed at super-magnified view (450x) before endoscopic resection. Blinded pathological assessment was obtained. RESULTS: Fifty-two lesions were examined in 49 patients (17 polypoid and 35 nonpolypoid). Final pathological diagnosis was normal mucosa or hyperplastic polyp in ten cases, low-grade adenoma in 29, high-grade adenoma in 11, and submucosal invasive cancer in two cases. Positive predictive values of each EC group were 100%, 93.1%, 90.1%, and 100%, respectively. ECS diagnosis correlated completely with pathology in the differentiation between neoplastic and nonneoplastic lesions. CONCLUSIONS: ECS enabled observation of colorectal lesion at a subcellular level in vivo. The classification of ECS images had a good correlation with the final pathological diagnosis. ECS was useful to differentiate between neoplastic and nonneoplastic lesions.

Can magnification endoscopy detect residual adenoma after piecemeal resection of large sessile colorectal lesions to guide subsequent treatment? A prospective single-center study.

PURPOSE: This study assesses the ability of magnification endoscopy to detect residual adenomatous tissue after endoscopic piecemeal resection of colorectal polyps and evaluates the impact of the technique on the incidence of recurrence. METHODS: Patients who underwent endoscopic piecemeal resection for large (>2 cm) sessile colorectal polyps were included. After endoscopic piecemeal resection, both the outer resection margins and the central severed area were inspected with magnification endoscopy. Completeness of excision as determined from the magnified surface pattern was compared with that determined histologically. Areas of incomplete resection were treated with additional resection or argon plasma coagulation. RESULTS: A total of 77 lesions were resected. Mean size of the resected lesions was 29 +/- 6 mm (range, 23-60). Complications of resection occurred in eight patients (seven had immediate bleeding that was successfully managed with hemoclip application, and one had delayed perforation that was treated surgically). The sensitivity of magnification endoscopy for predicting remnant adenoma at resection margins was 98% (95% confidence interval 90-100); specificity was 90% (95% confidence interval 79-100). Overall accuracy was 94.5% (95% confidence interval 87.2-98.6). On a mean follow-up of 32 months (range, 18-46) the recurrence rate was 2.6%. CONCLUSIONS: Magnification endoscopy is accurate at predicting remnant tissue after endoscopic piecemeal resection of large sessile colorectal polypoid lesions. When applied on both outer margins and inner portions of the severed area, it is helpful as a guide to subsequent further treatment to decrease recurrence.

Self-assembled hydro-jet system for submucosal elevation before endoscopic resection of nonpolypoid colorectal lesions (with video).

BACKGROUND: Endoscopic resection of colorectal nonpolypoid lesions requires adequate submucosal lifting of the lesion. OBJECTIVE: To evaluate a self-assembled hydro-jet system for tissue elevation to improve endoscopic resection of colorectal nonpolypoid lesions. DESIGN: Prospective study. SETTING: Single-center teaching hospital. MAIN OUTCOME MEASUREMENTS: Efficacy and safety of the hydro-jet system and rate of complete resection. RESULTS: The system was clinically applied in 31 patients to remove a total of 34 lesions throughout the colon. An adequate submucosal fluid cushion was achieved in all but 1 case without any lifting-associated complications. Complete endoscopic resection was possible in all 33 lifted lesions by using a snare. The size of the resected lesions ranged from 7 to 60 mm. Major intraprocedure bleeding occurred in only 1 case. No perforation or late bleeding was recorded. Histological examination showed a selective accumulation of fluid in the submucosa with edema and dissociation of submucosal structures, with no damage to the muscularis mucosa and very limited "burn effect" hampering assessment of radial margins. LIMITATIONS: Lack of controls. CONCLUSIONS: This inexpensive system allows safe and rapid submucosal lifting of colorectal nonpolypoid lesions to assist endoscopic resection.

Localized amyloidosis of the stomach: a case report.

We report an unusual case of primary amyloidosis of the stomach in a patient complaining of dyspeptic symptoms. The diagnosis was confirmed histologically and other gastrointestinal site or systemic involvement was ruled out. Uncharacteristic dyspeptic symptoms may hide this rare metabolic disease.

Cortocircuitos venosos portosistémicos intrahepáticos: diagnóstico mediante ecografía Doppler / Intrahepatic portasystemic venous shunts: diagnosis by Doppler ultrasound

Los cortocircuitos venosos portosistémicos intrahepáticos (CVPI) son lesiones vasculares venosas que ponen en comunicación vasos portales intrahepáticos con venas hepáticas. Pueden presentarse en pacientes con hipertensión portal (HP) o ser descubiertos de manera incidental, por lo que, en su etiología, se postula un origen congénito o adquirido. La ecografía Doppler como método no invasivo permite el diagnóstico de estas comunicaciones anómalas al visualizar los vasos y la dirección, velocidad y volumen del flujo en el interior de la comunicación. Presentamos cuatro casos de CVPI (AU)

El abuso sexual y violación en menores del 15 años de edad: Acarigua, Estado Portuguesa, Venezuela 1997 / Sexual abuse and violation in younger than 15 years of age: Acarigua, Portuguesa State, Venezuela 1997

Para determinar el número de casos de abuso sexual y violaciones en menores de 15 años de edad, denunciados a las autoridades de Acarigua Edo. Portuguesa durante 1996, se realizó una investigación de tipo descriptiva retrospectiva. De 131 casos registrados, tomamos una muestra de 81 menores, recolectando la información de los expedientes, en tres partes; datos de la víctima y características del suceso; datos del victimario y ambiente familiar de la víctima. El 91,35 por ciento de la población era femenina, estudiantes (80,25 por ciento), entre 12 y 15 años (69,13 por ciento). El tipo de agresión frecuentemente fue el abuso sexual con penetración vaginal (56,79 por ciento) y 40,74 por ciento presentó desfloración completa antigua, 10,41 por ciento presentó embarazos, ocurriendo en el hogar de la víctima (34,56 por ciento), de noche (34,50 por ciento), siendo un conocido (40,74 por ciento) o novio (37,03 por ciento) el agresor, con edades entre 16 y 20 años (31,70 por ciento) masculino, utilizando conducta emocional (49,38 por ciento) y fuerza (48,14 por ciento) para someterla. El nivel socioeconómico de las agredidas fue bajo (61,72 por ciento) con padres solteros (61,72 por ciento). La madre (77,77 por ciento) una semana después realiza la denuncia. Se requieren cambios macrosociales para erradicar las causas que generan el abuso sexual y violaciones en los menores de edad, debiendo darles una educación sexual que les permita alcanzar una mayor plenitud personal y los proteja de la explotación, embarazos no deseados y de enfermedades de transmisión sexual, integrando a los padres y a los pediatras en esta labor
