DNA remodelling during endoreplication appears to be a strong developmental characteristic in orchids. In this study, we analysed DNA content and nuclei in 41 species of orchids to further map the genome evolution in this plant family. We demonstrate that the DNA remodelling observed in 36 out of 41 orchids studied corresponds to strict partial endoreplication. Such process is developmentally regulated in each wild species studied. Cytometry data analyses allowed us to propose a model where nuclear states 2C, 4E, 8E, etc...

Haemosuccus Pancreaticus is defined as upper gastro intestinal (GI) bleeding from the ampula of vater via the pancreatic duct. It is most commonly associated with pancreatic inflammation, erosion of the pancrease by aneurysm or pseudo-aneurysm of the splenic artery. We report a 69 year old man with previous history of acute pancreatitis who was admitted with recurrent haematemesis. Initial upper GI endocopy was normal, while admitted, he collapse with abdominal pain and hypotension. He was resuscitated with blood and intravenous fluid...

INTRODUCTION: Data from colorectal endoscopic mucosal resection (EMR) of lesions 6 cm and greater is scant. Endoscopists may welcome these lesions as challenges, but what is the longterm outcome and therefore what should patients be advised before consenting to these procedures? METHODS: Prospective data has been collected for over 10 years by a single endoscopist (JMS) on his EMR practice and the database was interrogated for Colorectal resections of flat or sessile polyps, greater or equal to 6 cm...

INTRODUCTION: Capsule endoscopy (CE) is firmly established as a standard procedure in the diagnostic algorithm of occult or obscure gastrointestinal bleeding and Crohn's disease. Despite its excellent diagnostic yield, missing expertise, reading time and financial expenditure limit an area-wide availability. A multicentric cooperation might compensate these disadvantages. METHODS: CE device was bought by a central hospital (CH). Requested equipment is transported to the network partner (NP) and the procedure performed at the spot in personal responsibility...

UNLABELLED: Antrochoanal polyps are more frequent in children than in adults. Patomechanism of their development is still unclear. New diagnostic methods allow precise examination of lateral nasal wall pathologies. AIM OF THE STUDY: Aim of the study is an evaluation of endoscopic examinations and CT scans of lateral walls in 15 children with chronic sinusitis and diagnosed antrochanal polyps. MATERIAL AND METHODS: Both groups of children, those with chronic sinusitis and those with diagnosed antrochoanal polyps, were compared according to the results of the endocopies and CT scans...

The authors have used bone endoscopy (medulloscopy) to improve the accuracy of the conventional technique for core decompression and grafting in 36 hips with avascular necrosis of the femoral head. Endocopy was found to facilitate debridement of the necrotic bone and to decrease the risk of perforation of the cartilage during debridement. The endoscopy-assisted technique failed, however, to improve the final outcome of core decompression and grafting in more advanced stages of osteonecrosis. Based on this experience, the authors do not recommend core decompression, with or without endoscopic assistance, in advanced stages of avascular necrosis, but they suggest using endoscopic assistance during decompression in small-size lesions...

BACKGROUND: Flexible endoscopy is a vital component of gastrointestinal surgery. It has and will replace many of the surgical procedures now commonly performed. Flexible endoscopy, unfortunately, is not an integral part of surgical residency training based on resident operative experience as reported by the Residency Review Committee. Moreover, general surgeons have deferred the practice of flexible endoscopy to the gastroenterologists because of concerns over turf battles and referral patterns...

In the period from 1977 to 1979, 40 transethmoidal-transphenoidal operations were carried out on 35 patients with hypophyseal adenomas. The patients were subdivided into appropriate groups and showed congruency with other statistics. The transethmoidal procedure permits the shorter anatomical way, can be combined with transnasal instruments and in particular does not involve the later and late consequences of septum operations. The transphenoidal procedure usually is considerably less onerous for the patients than the intracranial subfrontal operation...
