Ectopic Pancreas Associated with Choledochal Cyst and Multiseptate Gallbladder

Abstract: Congenital choledochal cyst is a rarely seen malformation of childhood, particularly when associated with multiseptate gallbladder or ectopic pancreas. The current case represents a 15-day-old boy with jaundice. Ultrasonography suggested a cystic lesion, probably of the common bile duct. The patient underwent a total excision of type I choledochal cyst and gallbladder with Roux-en-Y anastomosis, and a wedge biopsy from the liver. Gross examination revealed multiple septa dividing the gallbladder into multiple compartments. The outer and inner surfaces of the choledochal cyst were unremarkable. Microscopically, the cyst wall was composed of dense fibrous tissue with a single layer of cubic to columnar cells constituting the overlying epithelium. Serial sections incidentally revealed ectopic pancreatic tissue lying along the cyst wall characterized by acini, islets, and ductal structures with endocrine cells reactive for chromogranin A. Septa dividing the gallbladder were composed of fibrotic stalks containing smooth muscle fibers. Areas of papillary hyperplasia and intestinal metaplasia of gallbladder epithelium were also noted. The liver biopsy specimen demonstrated the presence of intrahepatic bile ducts, subsequently confirmed by cytokeratin 7. To our knowledge, this case represents the 1st one associated with these 3 entities and only the 2nd choledochal cyst with ectopic pancreatic tissue in its wall.

Histological Evaluation of the Effect of Concentrated Growth Factor on Bone Healing.

Abstract: Objectives:The aim of this study was to evaluate the effects of concentrated growth factors (CGF) on the healing of peri-implant bone defects in an animal model.Study Design:Twenty 4-month-old New Zealand White rabbits, each with an average weight of 3.5 kg, were used in this blinded, prospective, e

Guidelines for standard photography in gross and clinical anatomy

Abstract: Photography has a widespread usage in medicine and anatomy. In this review, authors focused on the usage of photography in gross and clinical anatomy. Photography in gross and clinical anatomy is not only essential for accurate documentation of morphological findings but also important in sharing knowledge and experience. Photographs of cadavers are supposed to demonstrate the required information clearly. Thus, photographs should be taken with certain techniques in order to obtain high quality and standardization. Camera, lens, lighting, background, and certain photographic techniques are among the factors to achieve precise images. A set of suggested guidelines for accomplishing these standards are given for anatomists.

Monitoring deformations on engineering structures in Kozlu Hard Coal Basin

Abstract: Underground coal mining activities in Kozlu Hard Coal Basin have reached a level affecting ground layers inside the mining seams and the surface just above the mining operations, causing movements in vicinity of the basin. The movements emerge as collapsing in vertical direction and as sliding, curling and bending in horizontal direction and are termed mining subsidence since they exhibit themselves in ground layers and on earth surfaces in mining environments. These mining-induced movements cause damages and destructions on structures inside and on the surface of mining grounds, and the dimensions of these damages depend upon quality of structures and magnitude of movements. In order to contribute toward a solution to these problems and to mitigate the effects arising during and after mining activities, one should identify and investigate damage prone movements and determine the movement–time relationship. Therefore, it is immensely important to observe, investigate, and measure these movements in regions where mining activities take place. This study focuses on the surface movement-related deformations on the engineering structures in the basin such as Kozlu Seaport and some part of the Zonguldak-Kozlu Road. For this reason, subsidence monitoring points were established on the engineering structures in the basin in a geodetic network concept, and three periods of precise leveling and static GPS observations were conducted. Analyzing these two types of geodetic observations, active and residual subsidence effects were determined for both Kozlu Seaport and the Road nearby.
