Background: McKittrick-Wheelock syndrome mostly results from colorectal villous adenoma and is characterized by dehydration, hyponatremia, hypokalemia, and prerenal azotemia. Case Report: We report the case of an 84-year-old patient with rectal villous adenoma, presenting with chronic mucous diarrhea for 2 years and subsequent prerenal azotemia. After fluid and electrolyte replenishment, the pa...

The placental development is a complex process, in which any disturbance can induce changes with grave consequences for the offspring. Villi and villous vascularization development is in, and underdevelopment can lead to villous placental insufficiency. This paper aims to analyze the arterial and venous vasculature of the placenta, both macroscopic and morphologically, by different injection te...

Scanning Electron Microscope (SEM) was used to examine villous structures at different parts in the small intestines of 22-week-old chickens. Duodenum revealed plate-like villi with large number of goblet cells on the duodenal epithelium. Jejunum and ileum both revealed leaf-like villi, but the amount of goblet cells was greater in the jejunum. A putative effect of villous structures on the int...

Human cytomegalovirus (HCMV) infection is transmitted from the infected mother to the placenta and fetus. Virus replicates in the decidua, invasive cytotrophoblasts that breach the uterine vasculature and villous cytotrophoblasts underlying syncytiotrophoblasts, then reaches blood vessels in the villus core. Virus replication, fibrosis, and edema result in a hypoxic intrauterine environment and...

Symptomatic disease from Strongyloides stercoralis has been recognized for the first time in Trinidad. Five cases are reported, all showing clinical features suggestive of a sprue-like syndrome. Subtotal jejunal villous atrophy was seen in one case and partial villous atrophy in two. Three patients had laparotomies because of suspected partial intestinal obstruction. A sprue-like syndrome in ce...

These advances have become possible because of the ability to measure tumour load with hCG, diagnose hydatidiform mole in early pregnancy by ultrasound, and the ability to determine whether or not metastases are present on CT and MRI, together with greater understanding of the pathology and molecular physiology of trophoblastic neop...

Biopsies from 56 patients with endoscopically normal duodenal bulbs, duodenitis, or duodenal ulceration were studied for counts of plasma cells, polymorphs, and eosinophils and extent of gastric metaplasia, villous atrophy, and mucosal oedema. A correlation matrix showed that the counts of different types of plasma cells were closely correlated with each other and that there was also a close co...

AIMS To determine whether the expression of proliferating cell nuclear antigen (PCNA) in villous cytotrophoblast could distinguish between placental tissue from a hydropic abortion and that from a partial hydatidiform mole. METHODS Tissue from 18 partial hydatidiform moles, 15 hydropic abortions, five normal first trimester placentas and five normal full term placentas were immunostained for ...

We present an exceptional case of a giant urachal tumor, consisting of both villous adenoma and mucinous adenocarcinoma of the urachus. The tumor was incidentally discovered during investigations for renal failure. Initial transurethral biopsies showed only a villous adenoma of the urachus. Although the biopsies showed no malignancy, a radical cystoprostatectomy and broad excision of the urachu...
