Foreign body ingestion is a common problem in children. Most of these foreign bodies spontaneously pass through the gastrointestinal tract. When there is a persistent foreign body in the abdomen, it is impossible to make a diagnosis without exploration. We herein present the case of a child who was admitted to our hospital with a coin trapped in Meckel's diverticulum and our laparoscopic approach in this case. The diagnosis of Meckel's diverticulum should be considered when there is a prolonged lodgment of a foreign body in the right lower quadrant, and the laparoscopic approach is the preferred choice in these cases.

complications of Meckel's diverticula are relatively common, there has not been a reported case, to our knowledge, of foreign bodies impacted within a Meckel's diverticulum. We report herein a case of a 2-year-old child who had two pennies trapped in a Meckel's diverticulum. This case demonstrates that foreign objects in the right lower quadrant that do not progress may be impacted in a Meckel's diverticulum.

Introduction: Congenital duodenal diverticula are a rare anomaly. The discovery of one in association with an ingested foreign body has only been reported on one previous occasion. In this challenging presentation, the presence of the coin led to the correct diagnosis. Patients with congenital duodenal anomalies may present a number of associated abnormalities. Interestingly, after the discovery of his intraluminal duodenal diverticulum, we searched and found that our patient presented a number of associated pathologies, as described in the literature. Case presentation: Our patient was a 36-year-old man, Caucasian, a kidney transplant recipient who presented with abdominal pain, vomiting and fever after an episode of pancreatitis. Because of a history of behavioral problems associated with intellectual impairment, including a compulsion to swallow coins during childhood, an abdominal radiograph was performed. Surprisingly, the radiograph revealed a radiopaque shadow in the central abdominal area. The findings of the ultrasound examination and computed tomography scan were suggestive of dilated biliary and pancreatic ducts. We performed an endoscopic retrograde cholangiopancreatography, which led to confirmation of the suspected coin above an obstructing intraluminal duodenal diverticulum with associated biliary ductal dilation. Upon retrieval of the coin, it was found to be a 1975 copper two-cent piece out of circulation in Australia for a large number of years. Conclusions: Foreign body retention in the gastrointestinal tract in an adult could be a sign of underlying mechanical pathology. Intraluminal duodenal diverticulitis can have a varied presentation, including life-threatening complications. Awareness should be raised of the conditions associated with congenital duodenal anomalies in adults, including renal, hepatobiliary and cardiac defects, many of which were present in our case.

We report an unusual case of acute abdomen due to axial torsion and infarction of a Meckel's diverticulum in a 13-year-old boy and illustrate the versatility of laparoscopy in the diagnosis and management of acute surgical abdomen in children. We believe that this is only the third case reported in a child of torsion of a Meckel's diverticulum and the first to be managed by laparoscopic resection.

To retrospective review the laparoscopic management of Meckel Diverticulum (MD) in two Italian Pediatric Surgery Centers. Between January 2002 and December 2012, 19 trans-umbilical laparoscopic-assisted (TULA) procedures were performed for suspected MD. The children were hospitalized for gastrointestinal bleeding and/or recurrent abdominal pain. Median age at diagnosis was 5.4 years (range 6 mo-15 years). The study included 15 boys and 4 girls. All patients underwent clinical examination, routine laboratory tests, abdominal ultrasound and technetium-99m pertechnetate scan, and patients with bleeding underwent gastrointestinal endoscopy. The abdominal exploration was performed with a 10 mm operative laparoscope. Pneumoperitoneum was established based on the body weight. Systematic overview of the peritoneal cavity allowed the ileum to be grasped with an atraumatic instrument. The complete exploration and surgical treatment of MD were performed extracorporeally, after intestinal exter...
The rainfall variability observed since the 1970s has resulted in a succession of years of drought. Generally, this has raged for thirty years in West Africa, in the Sahelian countries, and the countries along the Gulf of Guinea. It has resulted in severe decreases in rainfall and stream flows. This paper focuses on taking into account the rainfall variability on surface flows of the Agnéby watershed to better understand the evolution of the hydrological regime. To achieve this, the study was based on daily rainfall and flow data from 1955 to 2015. An analysis of the hydropluviometric indices has been performed. These indices associate several complementary methods such as the detection tests of the break in the average, the procedure for the segmentation of hydrological time series, the runoff coefficient, and the hydroclimatic average coefficient. The analysis reveal ruptures around 1960s and 1980s. These result in hydrological responses with deficits of -54% and -36%. A significant resumption of the average flows is observed from 1996, with a rainfall surplus of + 7%, which has resulted in a hydrological response of 149%. This latter finding points out the entry into a new, more humid climatic period than that of the 1960s and 1980s at the scale of the Agnéby basin. This is confirmed by the increase of the hydroclimatic average coefficient up to 130% since the end of the 2010 decade. The annual rainfall obtained are also well comparable with those of the wet period (1997-2015) with a cumulative rainfall varying between 1280 mm and 1760 mm.

The action of taphonomic processes on rock fragments or on lithic artifacts may generate stone tool pseudomorphs. This is particularly the case if postdepositional processes acting upon lithics include percussion and/or pressure mechanisms. Trampling is one of the most ubiquitous taphonomic processes in archaeological contexts, in particular surface loci. In this paper, we present a techno-morphological characterization of experimental lithic pseudotools produced by human treadage in order to contribute to the identification of the taphonomic background noise within different regions. Experimental artifacts were analyzed using the main classification methodology applied by lithic analysts in Argentina, to maximize the comparability of the outcomes of this research. Edge damage, stone tool type, flake scar size, flaking pattern, etc., are described. Trampling experiences included several raw materials represented within Pampa and Patagonia archaeological assemblages. It allowed us to explore variations within trampling effects on different rocks and substrates as well as to generate expectations on the contribution of pseudotools to the archaeological assemblages. Keywords: Lithic technology; Lithic taphonomy; Actualism; Pseudotool; Clasificación. Resumen La acción de los procesos tafonómicos sobre litos naturales o artefactos puede generar pseudomorfos de instrumentos líticos. Esto es particularmente cierto para los procesos postdepositacionales que incluyen a los mecanismos de percusión y presión en su funcionamiento. Entre ellos se encuentra el pisoteo, uno de los procesos tafonómicos más ubicuos en distintos contextos arqueológicos, especialmente aquellos de superficie. A fin de contribuir a la identificación del ruido de fondo tafonómico en diferentes regiones, en este trabajo realizamos la caracterización morfológica de pseudoinstrumentos líticos producidos experimentalmente por pisoteo humano. Para maximizar la comparabilidad de nuestros resultados, analizamos las piezas experimentales siguiendo la propuesta morfo-tipológica de uso más difundido en Argentina. Se describen el tipo de rastro complementario, grupos tipológicos, extensión de los filos, la anchura y patrón de los lascados, entre otros aspectos. Las experiencias incluyeron el pisoteo sobre sustrato duro y blando de piezas confeccionadas con una amplia variedad de materias primas líticas representadas en diversos conjuntos arqueológicos de Pampa y Patagonia. Ello permitió explorar las variaciones existentes en los efectos del pisoteo sobre distintas rocas y sustratos, así como generar expectativas sobre la contribución del ruido tafonómico a los conjuntos líticos bajo la forma de pseudoinstrumentos. Palabras clave: Tecnología lítica; Tafonomía lítica; Actualismo; Pseudoinstrumento; Clasificación.
