OBJECTIVE To assess the safety of confining histological examination to gall bladders with radiological and macroscopic features suggestive of cancer. DESIGN Retrospective study. Setting Department of Histopathology, National Hospital of Sri Lanka. METHOD Analysis of all cholecystectomies performed at a tertiary care hospital during a one year period. Computerised histopathological reports ...

Genetic variation in plants is known to influence arthropod assemblages and species interactions. However, these influences may be contingent upon local environmental conditions. Here, we examine how plant genotype-based trophic interactions and patterns of natural selection change across environments. Studying the cottonwood tree, Populus angustifolia, the galling aphid, Pemphigus betae and it...

BACKGROUND Octreotide treatment may be associated with gall stone development in up to 50% of patients with acromegaly. Two new sustained-release formulations of somatostatin analogue have been recently developed: lanreotide SR (Somatuline) and octreotide LAR (Sandostatin LAR). The incidence of gall-stone development in patients receiving these drugs has been shown to be less than 20%, but the ...

there have been only isolated reports of gall stones occurring during octreotide treatment.' Gall bladder contraction and cholecystokinin secretion in response to food are almost abolished by its administration4 and may contribute to stone formation. The high incidence of gall stones might have been due to the higher doses of the drug which we used. None of our patients had symptoms from the ga...

Gall-bladder duplication is a rare anatomical variation, which can affect safe performance of cholecystectomy and be a cause of persistent symptoms and a need for reoperation in case of accessory gall-bladder omission. A case of successfully performed elective laparoscopic cholecystectomy in a patient with duplicated gall-bladder accidentally intraoperatively disclosed is presented. The identif...

The liver, gall bladder, and ventral pancreas are formed from the posterior region of the ventral foregut. After hepatic induction, Sox17+/Pdx1+ pancreatobiliary common progenitor cells differentiate into Sox17+/Pdx1- gall bladder progenitors and Sox17-/Pdx1+ ventral pancreatic progenitors, but the cell-extrinsic signals that regulate this differentiation process are unknown. This study shows t...

The effects of cigarette smoking and parity on the development of symptomatic gall bladder disease remain controversial. These relations have been examined in a cohort of 46000 women followed for up to 19 years during the Royal College of General Practitioners' (RCGP) oral contraception study. During follow up, 1087 women were recorded as experiencing their first ever episode ofsymptomatic chol...

This study discusses the percentage of Hartmann’s pouch of gall bladder and whether the Hartmann’s Pouch is an anatomical variation or pathological presentation in North Coastal Andhra Pradesh. India. Knowledge of relevant anatomy is important for the safe execution of any operative procedure,specifically in laparoscopic cholecystectomy. It has been recognized since long that misinterpretation ...

Many studies over the past twenty years have documented the richness of arthropod galling species around the world, and some have proposed hypotheses to explain local and global patterns of galling species richness. However, few studies have been directed toward understanding how the gall-inducing species are locally distributed. The aim of this study was to determine the distribution of gall-i...

The frequency of galls induced by Anisodiplosis waltheriae Maia, a recently described species, on Waltheria indica L. was studied. W indica is an invasive weed in regeneration areas of Atlantic Forest in southeastern Brazil. Plants were collected in May 2004 and above-ground biomass, main stem length, number of leaves, number of galls per leaf and leaf area of each individual were recorded. Nea...
