A benign epithelial tumor with a glandular organization.
A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth. (Dorland, 27th ed)
An adenoma of the large intestine. It is usually a solitary, sessile, often large, tumor of colonic mucosa composed of mucinous epithelium covering delicate vascular projections. Hypersecretion and malignant changes occur frequently. (Stedman, 25th ed)
Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.
A benign neoplasm of the ADRENAL CORTEX. It is characterized by a well-defined nodular lesion, usually less than 2.5 cm. Most adrenocortical adenomas are nonfunctional. The functional ones are yellow and contain LIPIDS. Depending on the cell type or cortical zone involved, they may produce ALDOSTERONE; HYDROCORTISONE; DEHYDROEPIANDROSTERONE; and/or ANDROSTENEDIONE.
A benign epithelial tumor of the LIVER.
A benign tumor of the anterior pituitary in which the cells do not stain with acidic or basic dyes.

It is characterized by upper body OBESITY; OSTEOPOROSIS; HYPERTENSION; DIABETES MELLITUS; HIRSUTISM; AMENORRHEA; and excess body fluid. Endogenous Cushing syndrome or spontaneous hypercortisolism is divided into two groups, those due to an excess of ADRENOCORTICOTROPIN and those that are ACTH-independent.
Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with familial adenomatous polyposis (ADENOMATOUS POLYPOSIS COLI) and GARDNER SYNDROME, as well as some sporadic colorectal cancers.
A condition of abnormally elevated output of PARATHYROID HORMONE (or PTH) triggering responses that increase blood CALCIUM. It is characterized by HYPERCALCEMIA and BONE RESORPTION, eventually leading to bone diseases. PRIMARY HYPERPARATHYROIDISM is caused by parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS. SECONDARY HYPERPARATHYROIDISM is increased PTH secretion in response to HYPOCALCEMIA, usually caused by chronic KIDNEY DISEASES.
Tumors or cancer of the SALIVARY GLANDS.
Tumors or cancer of the COLON.

Villous adenoma of the bile ducts: a case report and a review of the reported cases in Korea. (1/60)

Villous adenomas are benign epithelial lesions with malignant potential which can occur at any site in the gastrointestinal tract. They are usually encountered in the rectum and colon, less frequently in the small bowel and very rarely in the biliary trees. Nine cases of bile duct villous adenomas have been reported in the literature. However, 4 cases of bile duct villous adenomas have been reported in the Korean literature. Recently, we experienced a case of villous adenoma in the common hepatic duct in a 77-year-old man presenting with obstructive jaundice in which preoperative histologic diagnosis of villous adenoma played a critical role in managing this patient. Herein, we present a case report of bile duct villous adenoma and a review of the reported cases in Korea to help define and manage this rare disease entity in the bile ducts. In addition, confusing nomenclature of bile duct adenomas is discussed.  (+info)

Treatment options for villous adenoma of the ampulla of Vater. (2/60)

INTRODUCTION: Duodenal villous adenoma arising from the ampulla of Vater has a high risk of malignant development. Excluding associated malignant disease prior to resection of an adenoma of the ampulla is not always possible. Therefore, the surgical procedure of choice to treat this rare tumour is still controversial. OBJECTIVE: To evaluate retrospectively results of treatment of villous adenoma arising from ampulla of Vater with dysplasia or associated carcinoma limited to the ampulla. PATIENTS AND METHODS: From 1985 to 1996, eight patients have been diagnosed with ampullary villous adenoma suitable for resection. We have reviewed treatment, morbidity, mortality, follow-up and final outcome. RESULTS: Pancreatoduodenectomy (PD) was performed in 4 patients. Transduodenal ampullectomy and endoscopic resection was performed in 2 patients each. There was no perioperative mortality. None of the patients had biliary, pancreatic or intestinal leakage but two patients who underwent PD had minor postoperative complications. The mean follow-up was 44 (range: 6-132) months. Villous adenoma was associated with adenocarcinoma in 50% of the cases (4/8 patients). During the follow-up both patients who underwent transduodenal ampullectomy developed recurrent disease. All patients initially treated by PD are alive without evidence of recurrent disease. CONCLUSIONS: Treatment of villous adenoma of the ampulla must be individualized within certain limits. In our series, PD achieve good results and it appears to be the procedure of choice in order to treat villous adenomas with proved presence of carcinoma, carcinoma in situ or severe dysplasia. Endoscopic or local resection may be appropriate for small benign tumours in high risk patients.  (+info)

Adenoma of the papillae of Vater. Report of eleven cases. (3/60)

Eleven patients with a preoperative diagnosis of adenoma of the papillae of Vater were followed up during the fifteen-year period from 1984 till 1998 in the Oulu University Hospital. Seven patients were treated primarily by transduodenal excision without any recurrences so far. One of these seven patients was found to have adenocarcinoma in a histological examination. Active surgery for adenoma of the papillae of Vater is recommended because of the precancerous nature of the lesion, and because malignancy cannot always be detected by endoscopic biopsies. Transduodenal excision could be recommend for patients at high operative risk, especially in cases with small adenomas and low-grade dysplasia, where histologically free resection margins can be achieved, but pancreaticoduodenectomy should still be performed on patients at low operative risk.  (+info)

Overexpression of cyclin D1 mRNA in colorectal carcinomas and relationship to clinicopathological features: an in situ hybridization analysis. (4/60)

Increased expression of a key cell cycle regulator, cyclin D1, may have relevance to carcinogenesis and clinicopathological characteristics of some cancers. This study represents the first application of in situ hybridization, ISH, to detect cyclin D1 mRNA in tissue sections from colorectal carcinomas. This approach was selected because of its unique potential to clarify whether increased expression of cyclin D1 mRNA correlates with clinical and pathological parameters. The ISH ofa non-radioactive oligonucleotide probe (Biogenex) was immunocytochemically detected in paraffin embedded sections from biopsy or resection specimens. Tumors ranged from well to poorly differentiated, and from stages A, B, C, and D. Ten year survival data were available on the majority of patients. Intensity of tumor and background (smooth muscle) signals were independently scored from 0 to 3. Overexpressed cyclin D1 mRNA was seen in 86% of cases compared to background. This frequency is similar to that reported for pancreatic carcinoma. The average signal intensity score in tumor foci was 1.9 with a background score of 0.05 (p<001). All cases showed specific staining judged by the cytoplasmic localization and a tumor signal:background ratio >1. Expression did not differentiate cancers based on grade, stage or survival (p>1), but did differentiate carcinoma and severe dysplasia from mild dysplasia. We conclude that ISH of cyclin D1 mRNA is an effective and relatively specific means of detecting activity of this gene in colonic neoplasms. The high frequency of overexpression implies that gene activity by itself is not likely to predict a tumor s biological or clinical behavior. On the other hand, these data suggest that increased cyclin D1 gene activity may be an early event in colorectal carcinogenesis. They also are consistent with findings showing cyclin D1 is inducible by a variety of oncogene products.  (+info)

Lack of mucin MUC5AC field change expression associated with tubulovillous and villous colorectal adenomas. (5/60)

BACKGROUND: MUC5AC is a secreted mucin aberrantly expressed by polypoid colorectal adenomas. It has been hypothesised that the "normal" surrounding colorectal mucosa expresses MUC5AC as a field change phenomenon that can be used to predict adenoma recurrence following resection. AIM: To determine if there is a field change of de novo MUC5AC expression in histologically normal rectal mucosa adjacent to villous and tubulovillous adenomas, and thus whether MUC5AC expression can be used as a marker of early tumour recurrence. METHODS: In a prospective cohort study paired mucosal biopsies of adenomatous and macroscopically "normal" mucosa were obtained from 11 patients with villous and 11 patients with tubulovillous adenomas who underwent primary resection for purpose of cure. The tissues were studied to determine MUC5AC gene expression by immunohistochemistry and in situ hybridisation. Patients were followed up by flexible sigmoidoscopy to detect the presence of early local recurrence. RESULTS: 10 villous adenomas showed mature MUC5AC glycoprotein and all 11 expressed MUC5AC mRNA. Five tubulovillous adenomas showed mature MUC5AC glycoprotein and 10 expressed MUC5AC mRNA. Neoexpression of the MUC5AC mucin gene was not detected in any of the mucosal biopsies taken adjacent to either villous or tubulovillous adenomas, even in three patients with early, locally recurrent disease. CONCLUSIONS: Aberrant MUC5AC gene expression is not a "field change" in the colorectal mucosa in patients with rectal adenomas and therefore cannot be used to predict local recurrence of villous and tubulovillous adenomas.  (+info)

Offline telepathology diagnosis of colorectal polyps: a study of interobserver agreement and comparison with glass slide diagnoses. (6/60)

BACKGROUND/AIMS: Technological advances have produced telepathology systems with high quality colour images and reasonable transmission times. Most applications of telepathology have centred on the remote diagnosis of frozen sections or remote real time expert opinions. This study investigates the reproducibility and accuracy of offline telepathology as a primary diagnostic medium for routine histopathology specimens. METHODS: One hundred colorectal polyps (50 hyperplastic, 50 adenomatous) were presented in a randomised order to five histopathologists as offline images on a telepathology workstation. Six images of each case were used: the slide label, a low power scan of all material on the slide, and four higher magnification views. The times taken to prepare the images, and to make the diagnoses, were recorded. Interobserver agreement was measured with kappa statistics and compared with the glass slide diagnoses. RESULTS: The kappa statistics for the interobserver agreement on the telepathology images lay in the range of 0.90-1.00, which is interpreted as excellent agreement, and were significantly higher than those for the glass slide diagnoses (range, 0.84-0.98; p = 0.001). The median time taken to capture the images for a case was 210 seconds. The median time taken to make a diagnosis from the telepathology images was five seconds, which was significantly shorter than for the glass slide diagnoses (median, 13 seconds; p < 0.0005). CONCLUSIONS: Offline telepathology has the potential to be a primary diagnostic medium for routine histopathology with a high degree of reproducibility and short diagnosis times. Further studies are required to validate offline telepathology for different types of specimens and different operators of the image capture system.  (+info)

Infectious endocarditis from Streptococcus bovis associated with colonic carcinoma: case report and literature review. (7/60)

BACKGROUND: Many studies in the literature have warned of the need for investigation of colonic lesions among patients, especially elderly ones, who have bacteremia and/or endocarditis from Streptococcus bovis. Bacteremia and infectious endocarditis from Streptococcus bovis may be related to the presence of neoplastic lesions in the large intestine and hepatic disease. AIM: This report describes a patient who presented infectious endocarditis from Streptococcus bovis associated with colonic carcinoma and tubular-villous adenomas. CONCLUSIONS: The finding of this bacterium among patients with septicemia and/or endocarditis is also related to the presence of villous or tubular-villous adenomas in the large intestine. For this reason, complete and detailed investigation of the large intestine must be performed in patients with infectious endocarditis, even in the absence of intestinal symptoms. An increased incidence of this condition or hepatic dysfunction has been reported among patients with infectious endocarditis from Streptococcus bovis. Patients with infectious endocarditis from Streptococcus bovis and normal colonoscopy may be included in the group at risk for developing colonic cancer. The knowledge that there is an association between endocarditis from Streptococcus bovis and carcinoma of the colon has important clinical implications. If the lesion can be discovered at an early stage, curative resection may become possible.  (+info)

Mucinous adenocarcinoma with superficial stromal invasion and villous adenoma of urachal remnants: a case report. (8/60)

This report describes a case of mucinous adenocarcinoma with superficial stromal invasion and villous adenoma originating in the dome of the urinary bladder. Although no urachal remnants were identified, the location suggested urachal derivation. Only two previous cases of urachal adenocarcinoma with features of early stromal invasion associated with a villous tumour have been described.  (+info)

The significance of expression of different mucins in succession of malignant transformation of colorectal polyps is not determined yet. The aim of the present study was to determine the pattern of expression of MUC1, MUC2, MUC5AC and MUC6 in colorectal polyps and to evaluate the applicability of using mucin expression in predicting the extent of malignant transformation in colorectal polyps. A total of 454 polyp specimens comprising 36 hyperplastic polyps, 15 serrated adenomas, 258 tubular adenomas, 114 tubulovillous adenomas, and 31 villous adenomas were included in this study, and were immunostained for MUC1, MUC2, MUC5AC and MUC6 by using mucin specific antibodies. MUC1 and MUC6 were absent in all hyperplastic polyps and their expression was higher in serrated and traditional adenomas. Only 5 cases including 2 serrated adenomas, 1 tubulovillous adenoma, and 2 villous adenomas stained negative for MUC2. The highest expression of MUC5AC was observed in serrated adenomas followed by tubular adenomas.

PY - 1992. Y1 - 1992. N2 - Samples of whole blood were obtained from 51 patients with newly diagnosed colorectal cancer as well as from 76 patients with neoplastic colorectal polyp, and from 30 healthy blood bank donors. Selenium was determined by the fluorimetric method. Significantly decreased selenium concentrations of blood samples from patients with colorectal cancer and villous adenoma were found. There was not any correlation between the blood selenium levels of patients with adenomatous polyp and the severity of dysplasia in removed polyps. The lowest mean selenium level in patients with villous adenoma indicates that selenium deficiency may be an important factor in the development of colorectal cancer arising from villous adenomas.. AB - Samples of whole blood were obtained from 51 patients ...
Answer: Villous adenoma. Histology: The dilated appendix is lined by adenomatous epithelium arranged both in a flat and undulating lining as well as a more overt villiform appearance. In areas, the epithelium is attenuated with abundant mucinous secretions. Mucin extravasation is seen under the adjacent colonic mucosa of the cecum. The mucin contains lymphocytes and histiocytes and elicits a surrounding giant cell reaction. No epithelial cells are noted within the mucin.. Discussion: A spectrum of lesions may be seen within the colon and appendix associated with mucin extravasation. At the most benign, one may have a dilated appendix lined by normal epithelium dilated with mucin as the result of an obstruction. Associated with the mucocele, there may be locally extravasation of mucin. Removal of the mucocele is curative. In the current case, there is a villous adenoma of the appendix with abundant mucin production. This mucin has also locally extravasated in the region of the appendix. In ...

The glandular structure of adenomas can be characterised as either tubular or villous. If more than 80% of the polyp contains tubular elements, the polyp is classified as a tubular adenoma (TA). If more than 80% of the polyp contains villous elements, it is classified as a villous adenoma. If neither tubular nor villous elements exceed 80%, then the polyp is classified as a tubulovillous adenoma. Most adenomas are TAs.. In most studies, an advanced adenoma (AA) is defined as an adenoma with high grade dysplasia, villous elements, or ⩾1 cm in size (as estimated using an open biopsy forceps). As patients with one or two TAs smaller than 1 cm are clearly not at increased risk of subsequent colorectal cancer,23 the focus of screening and surveillance has shifted progressively towards the AA and cancer, and away from the finding of a single TA. AAs have a greater risk of transforming into cancer, and patients with resected AAs have a greater risk of having recurrent AAs and cancers.23,24 ...
Results 1553 patients between the ages of 17 and 93 years (median age 55 years) had 18FDG PET CT performed during this period. Increased focal FDG uptake in the colon was detected in 179 of 1553 patients studied (11.5%). Endoscopic evaluation was performed in 71 (39.7%) of these patients, flexible sigmoidoscopy in 25 (35.2%) and colonoscopy in 46 (64.8%). Non-malignant pathology was found in 45 of 179 patients (25.1%); 17 (9.5%) were tubulovillous adenomas; 6 (3.4%) had villous adenomas; 9 (5.0%) were tubular adenomas; 4 (2.2%) hyperplastic polyps; 11 (6.1%) were normal colonic tissue and 1 (0.6%) was active inflammatory bowel disease. From the patients with increased 18FDG uptake in the colon, 19 (10.6%) were subsequently found to have adenocarcinoma on histology. This represents 26.8% of the 71 patients who received endoscopic evaluation. ...
Cancer of the colon. Endoscopic view of tubulovillous adenoma and a small adenocarcinoma in the transverse colon of the large intestine. A tubulovillous adenoma is a type of polyp (growth) in the gastrointestinal tract. These polyp are typically benign (non-cancerous) but may become malignant (cancerous). Adenocarcinomas are a form of colorectal cancer arising from glandular epithelial tissue. Adenocarcinoma accounts for 90-95 per cent of all colorectal cancers. Certain dietary habits, such as a diet high in fat, appear to be significant risk factors. - Stock Image C025/0077

A healthy body is needed for a person to function well in day to day activities. Potassium is important for the body to perform well; it can be found in meat products particularly in turkey and beef as well as from fish. Abundant in fruits like banana, avocado, orange and kiwi; it is also available from vegetables that are green and leafy, people have a rich source of the mineral. Low levels of potassium can be dangerous and lead to hypokalemia symptoms and treatment may become necessary.. Improper diet is not the sole reason why people suffer from low potassium level; it can also be due to gastrointestinal problems and the loss that occurs in the kidney. People who suffer from frequent vomiting or experience diarrhea incur losses in potassium levels. Those who have had bowel operation that resulted to ileostomy also experience potassium loss; the intake of laxative and the existence of villous adenoma are also factors to the mineral loss. Apart from detecting the loss, identifying hypokalemia ...
Colorectal adenomas are benign tumours with the potential to become malignant. Their incidence ranges from 2.9% to 11.5% depending on the series.1 Villous adenomas represent 10% of all colorectal adenomas and are normally asymptomatic, although 3% are hypersecretory.2 In 1954, McKittrick and Wheelock3 were the first to report hydroelectrolyte depletion secondary to severe diarrhoea caused by this type of tumour.. We present the case of a 72-year-old female patient with a history of hypertension, type 2 diabetes mellitus and hospitalisation two years prior due to pneumonia and hyponatraemia. She attend A&E following three days of epigastric pain together with melaena in the last 24h. The patients relatives reported occasional vomiting and severe diarrhoea in the previous days. Although the patient presented bradylalia and bradyphrenia, she was awake and oriented during the physical examination. She was found to be haemodynamically stable with vital signs within normal range. The abdomen was ...

Men typically start thinking about cancer risk during this decade. Lymphoma is still a significant possibility during this period; however, this is the decade when colon and prostate cancers begin to be considerable risks. The American Cancer Society recommends beginning screening during this time for both of these diseases if you are at high risk.. There are 150,000 new cases of colon cancer diagnosed in the U.S. each year. One in 20 persons develop this disease in their lifetime. A diet high in fat and red meat and low in vegetable fiber is associated with a greater risk. In addition, any family history of colon cancer increases lifetime risk of developing this malignancy threefold.. Colon cancer originates from colon polyps, which are mushroom-shaped growths that develop in the intestine. Although there are many types of colon polyps, colon cancer originates from just one type of polyp, called a villous adenoma. All other polyps do not become cancerous. Screening, starting during the 40s for ...

Background & Objectives: Tubular adenomas are rare benign epithelial tumours of breast affecting predominantly females of child bearing age group. Till now, very small number of cases have been reported in the literature. Present study was carried out to evaluate the clinico-pathological features of tubular adenoma cases diagnosed during three years study period along with discussion of possible differential diagnoses. Methods: Overall, 346 female breast biopsies were diagnosed as benign lesions in three years (2010-2012), of which 10 cases of tubular adenomas were identified. Available clinical, radiological and cytological data of these cases were analysed retrospectively in detail. Result: Tubular adenomas were identified from 16 to 48 years of age with a predilection to younger age group (60% within 30 years). Most of the tubular adenomas were small and circumscribed mimicking fibroadenoma in almost all the cases. Diagnosis of tubular adenoma in each case was possible only after histological
Background: Sporadic adenoma formation found on surveillance colonoscopies in patients with inflammatory bowel disease (IBD) represents a significant risk for cancer. Certain racial groups like African Americans (AA) are at increased risk of developing colorectal cancer (CRC), but there is conflicting literature on differences in sporadic adenoma formation. Some data suggests AA are at increased risk for large adenomas, more proximal lesions, and increased prevalence. These data, however, are studying the general population and to our knowledge no study has looked at differences in adenoma formation by race in IBD patients. The present retrospective study analyzes the prevalence of adenomas in IBD patients. Methods: All IBD patients who received a surveillance colonoscopy within the past year were included in the present study. Sporadic adenomas included serrated, tubular, villous, and tubulovillous adenoma formation. A database was created using Microsoft Excel and identifying information was
Sekine et al 16 used targeted next-generation sequencing and reverse transcriptase in a series of TSA and found that 24% showed RNF43 mutations.. In summary, RNF43 mutations are important in the serrated pathway, with SSA and TSA harbouring inactivating mutations. More specifically, RNF43 mutations are associated with the advent of dysplasia in these serrated polyps. RNF43 mutations are not present in hyperplastic polyps, sporadic tubular or tubulovillous adenomas. In colorectal carcinoma, RNF43 is associated with BRAF mutations and more prevalent in microsatellite unstable cases with loss of MLH-1 protein expression from MLH-1 promoter methylation.. RNF43 is exclusively and frequently altered in Lynch syndrome-associated adenomas (52%). In addition, Lynch syndrome-associated adenomas show variable mutation profiles depending on the mismatch repear (MMR) status. RNF43 mutations are exclusive to MMR-deficient adenomas (66%) and are mostly frameshift mutations affecting mononucleotide repeats. ...

N2 - RNF43 is an E3 ligase that suppresses the Wnt/β-catenin signaling pathway and is frequently mutated in microsatellite-unstable colorectal carcinoma. To investigate the pathogenetic role of RNF43 in the serrated pathway, we conducted mutation analysis of RNF43 in several types of colorectal neoplasms. RNF43 mutation was found in 2 of 20 (10%) sessile serrated adenomas, 10 of 36 (28%) traditional serrated adenomas, 7 of 37 (19%) traditional serrated adenomas with cytologic dysplasia, and 9 of 31 (29%) BRAF-mutated/microsatellite-stable colorectal carcinomas; however, no mutation was found in 30 tubulovillous/villous adenomas. All mutations were ...
41 patients underwent transanal excision using TEMS (KARL-Storz) or single port TAMIS (Covidien) kits. All patients went through the colorectal MDT with standardized MRI reporting. Average age was 70yrs (range=40-86). Mean hospital stay was 2.7 days. Complications- 1 had post-operative bleeding that required repeat surgery; 1 developed a pre-sacral collection that was treated with antibiotics.. 13 patients had tubulo-villous adenoma with high-grade dysplasia, 9 had invasive adenocarcinoma demonstrated on histology (3=T1SM1, 3=T1SM2, 3=T1SM3) and 1 had neuroendocrine tumor, others demonstrated benign dysplasia (15 had tubulo-villous adenoma with low-grade dysplasia, 3 with sessile serrated adenomas). 8/9 cancers had R0excision. One patient with T1SM3, who had R1 excision and another with T1SM2 and poor prognostic features on histology, underwent adjuvant chemoradiation. All patients had flexible sigmoidoscopy at 3 months. 5/41 had recurrent benign polyps (3 underwent endoscopic resections, 2 ...

Changes in the expression of mucin genes in gastrointestinal cancers is thought to contribute to the development of the disease. In our laboratory we have shown previously that MUC5AC is aberrantly expressed in rectosigmoid villous adenomas. However, the regulatory mechanisms underlying that altered profile of expression is unknown. In order to study its regulation at the transcriptional level, we have isolated and characterized 5.5 kb of the 5´-flanking region of the mouse Muc5ac mucin gene. The promoter is flanked by a TATA box and a transcriptional start site is located 22 bp downstream of the TATA box. Analysis of the sequence showed a high density of binding sites for Smad4, an essential factor in the signalling cascade activated by TGF-β (transforming growth factor-β), and Sp1, an important factor in the regulation of MUC5AC. This led us to study Muc5ac regulation by TGF-β. We show that exogenous addition of TGF-β to the cells induces Muc5ac endogenous expression, promoter activity ...

Results Seen in 83 men and 65 women ranging in age from 32 to 89 years and 127 were left sided with 22 in the right colon. Seventy-eight of the 149 TSAs showed evidence of another polyp (52.34%): 32 were low-grade tubular/tubulovillous adenomas (TAs/TVAs; 41%), 28 were HPs (36%) and 18 were SSAs (23%). Eleven of the 22 right-sided TSAs were associated with a precursor lesion (1 HP and 7 SSA). In addition, five TSAs showed more than one polyp type: TSA with TA/TVA and HP (3); TSA with TA/TVA and SSA (2). The TAs/TVAs were adjacent to the TSA but occurred as a separate discrete polyp, while HPs and SSAs were intermingled with the TSA and present at the base and surface of the lesion.. ...

Background: Gallbladder carcinoma (GBC) sometimes presents with nonspecific signs, without forming a mass, mimicking benign gallbladder (GB) diseases. On the contrary, benign GB diseases may mimic GBC. Material and Methods: We retrospectively reviewed 107 cases over a period of 3 years (May 2012-April 2015), which included 41 review cases and 66 departmental cases. Carcinoembryonic antigen (CEA) immunomarker expression was done. Results: In 27 of the 41 review cases, the diagnoses were benign diseases of GB associated with mild-to-moderate dysplasia of mucosal glands; however, after review in our department, it was found that of these 27 cases, nine cases were actually well-differentiated adenocarcinoma of GB with diffuse CEA expression and were mis diagnosed as benign diseases of GB with dysplasia ...

The standard treatment of rectal adenocarcinoma is total mesorectal excision (TME). The technique involves a low anterior rectal or colo-anal resection, very often associated with a protective stoma or abdominal-perineal resection with permanent colostomy. Transanal endoscopic microsurgery (TEM) allows access to tumors up to 20 cm from the anal margin, with minimal postoperative morbidity and mortality. Recent studies of T1 rectal adenocarcinomas consider TEM to be the technique of choice. However the treatment of T2 rectal cancers remains controversial. Chemotherapy and radiotherapy (CT/RT) has achieved a concomitant reduction in local recurrence and an increase in survival.. Hypothesis: Patients with rectal adenocarcinoma less than 10 cm from the anal margin and up to 4 cm in size, staged after endorectal ultrasound and MRI as T2 or superficial T3 N0-M0-N0-M0, who underwent surgery after preoperative local chemoradiotherapy (TEM), achieve effective results in terms of local recurrence similar ...

Infectious endocarditis results from bacterial or fungal infection of the endocardial surface of the heart and is associated with significant morbidity and mortality. Risk factors include the presence of a prosthetic heart valve, structural or congenital heart disease, intravenous drug use, and a recent history of invasive procedures. Endocarditis should be suspected in patients with unexplained fevers, night sweats, or signs of systemic illness. Diagnosis is made using the Duke criteria, which include clinical, laboratory, and echocardiographic findings. Antibiotic treatment of infectious endocarditis depends on whether the involved valve is native or prosthetic, as well as the causative microorganism and its antibiotic susceptibilities. Common blood culture isolates include Staphylococcus aureus, viridans Streptococcus, enterococci, and coagulase-negative staphylococci. Valvular structural and functional integrity may be adversely affected in infectious endocarditis, and surgical consultation is
Transanal endoscopic microsurgery (TEM) and transanal minimally invasive surgery (TAMIS) are similar techniques that allow surgeons to remove benign polyps and early stage cancers without the use of invasive surgery.. More about TEM. Developed in the 1980s, TEM was created to enable surgeons to remove polyps and tumors in the rectum using a port placed through the rectum and a microscopic lens. This technology has demonstrated precise excision of polyps and tumors with preservation of anal sphincter muscle control.. More about TAMIS. TAMIS was developed in 2009 and has been utilized for the same indications as TEM.. What is the difference between TEM and TAMIS? The primary difference between the two techniques is that a resterilized, reusable port is used for TEM, while a disposable port is used for TAMIS.. What are the benefits of TEM and TAMIS?. Many benefits have been noted for patients undergoing TEM and TAMIS: no visible incisions, decreased postoperative pain, faster recovery, and a ...

The occurrence of specific clinical complications was recorded and vegetations were assessed with respect to predetermined morphologic characteristics. The overall complication rates were roughly equivalent for patients with mitral (53%), aortic (62%), tricuspid (77%) and prosthetic valve (61%) vegetations, as well as for those with nonspecific valvular changes but no discrete vegetations (57%), although the distribution of specific complications varied ...
BACKGROUND: Transanal endoscopic microsurgery (TEM) allows locally complete resection of early rectal cancer as an alternative to conventional radical surgery. In case of unfavourable histology after TEM, or positive resection margins, salvage surgery can be performed. However, it is unclear if the results are equivalent to primary treatment with total mesorectal excision (TME). The aim of this retrospective study was to determine whether there is a difference in outcome between patients who underwent early salvage resection with TME after TEM, and those who underwent primary TME for rectal cancer. METHODS: From 1997 to 2011, early salvage surgery with TME after TEM was performed in 25 patients in our institution. These patients were compared with 25 patients who underwent primary TME, matched according to gender, age (±2 years), cancer stage and operative procedure. Data were obtained from the patients charts and reviewed retrospectively. No patients received preoperative chemotherapy. ...
CCNG2 gene was initially identified in 1996 and encodes for a protein that belongs to a family of cyclins homologous to CCNG1 (7). Previous studies have reported that CCNG2 participates in carcinogenesis and is a known tumor suppressor gene (15-17,20-26). CCNG2 gene expression is downregulated in thyroid (20), oral (21), ovarian (22), breast (23,24), gastric (16), esophageal (17), prostate (25), kidney (26) and colorectal (15) cancer cells.. Several aspects of CCNG2 behavior are associated with antitumor effects. Antitumor agents induce CCNG2 expression, which results in the inhibition of cancer cell proliferation (8-10). In breast cancer, CCNG2 knockdown induces multidrug resistance (8). In colorectal cancer, CCNG2 expression correlates with the tumor stage, lymph node metastasis, clinical stage, histological grade and overall survival (15). In gastric cancer, CCNG2 expression correlates with the extent of differentiation: CCNG2 expression is high in well-differentiated adenocarcinomas and low ...

Endoscopic removal of eroded Lap-Bands is a minimally invasive alternative to surgical removal that prerequires sufficient erosion through the gastric wall, that is, ≥180° of the gastro-oesophageal wall circumference. A 69-year-old woman presented with dysphagia due to a long-standing Lap-Band erosion, currently of a 60° circumference. Adhesions due to her extensive surgical history rendered surgical treatment undesirable, so a self-expanding stent was placed endoscopically to induce sufficient erosion for subsequent endoscopic removal. During therapy, the patient complained of ructus and dysphagia, probably related to an overly proximally (oesophageal) positioned stent. After a total of 12 weeks, far longer than the described stenting duration in the literature, the Lap-Band was found free in the gastric lumen and was successfully removed using an endoscopic loop. Stent-induced compression necrosis should be considered as a minimally invasive treatment option for Lap-Bands eroded for ...

I am using a fixed angle rotor centrifuge to separate the phases during TRIzol isolation. My problem is that the interphase clings to the sides of my tubes, leaving a smear of contamination in my aqueous phase - sometimes almost all the way to the top of it! I have just been pulling the aqueous phase being careful not to touch the side of the tube, but is that ok?? Also, by chance I just found that if I let the tubes sit at room temp for about 20 minutes (so this was after I already picked the very top of the aqueous phase and then just left the tubes), the interphase slides down to its place, leaving a clean aqueous phase above. So, I tried pulling more aqueous phase into separate tubes just to see what I get. Does anyone else have this problem? IS it a problem? Should I let the tubes sit until the phases settle into place before pulling the aqueous phase ...
