Tumors or cancer of the APPENDIX.
A worm-like blind tube extension from the CECUM.
Pathological developments in the CECUM.
A retention cyst of the salivary gland, lacrimal sac, paranasal sinuses, appendix, or gallbladder. (Stedman, 26th ed)
Surgical removal of the vermiform appendix. (Dorland, 28th ed)
A condition characterized by poorly-circumscribed gelatinous masses filled with malignant mucin-secreting cells. Forty-five percent of pseudomyxomas arise from the ovary, usually in a mucinous cystadenocarcinoma (CYSTADENOCARCINOMA, MUCINOUS), which has prognostic significance. Pseudomyxoma peritonei must be differentiated from mucinous spillage into the peritoneum by a benign mucocele of the appendix. (Segen, Dictionary of Modern Medicine, 1992)
Acute inflammation of the APPENDIX. Acute appendicitis is classified as simple, gangrenous, or perforated.
A multilocular tumor with mucin secreting epithelium. They are most often found in the ovary, but are also found in the pancreas, appendix, and rarely, retroperitoneal and in the urinary bladder. They are considered to have low-grade malignant potential.
An adenocarcinoma producing mucin in significant amounts. (From Dorland, 27th ed)
Carcinoma that arises from the PANCREATIC DUCTS. It accounts for the majority of cancers derived from the PANCREAS.
Neoplasms containing cyst-like formations or producing mucin or serum.
Unanticipated information discovered in the course of testing or medical care. Used in discussions of information that may have social or psychological consequences, such as when it is learned that a child's biological father is someone other than the putative father, or that a person tested for one disease or disorder has, or is at risk for, something else.
The collective name for the islands of the Pacific Ocean northeast of Australia, including NEW CALEDONIA; VANUATU; New Hebrides, Solomon Islands, Admiralty Islands, Bismarck Archipelago, FIJI, etc. Melanesia (from the Greek melas, black + nesos, island) is so called from the black color of the natives who are generally considered to be descended originally from the Negroid Papuans and the Polynesians or Malays.

Carcinoid of the appendix during laparoscopic cholecystectomy: unexpected benefits. (1/160)

Carcinoid tumors of the midgut arise from the distal duodenum, jejunum, ileum, appendix, ascending and right transverse colon. The appendix and terminal ileum are the most common location. The majority of carcinoid tumors originate from neuroendocrine cells along the gastrointestinal tract, but they are also found in the lung, ovary, and biliary tracts. We report the first case of elective laparoscopic cholecystectomy in which we found a suspicious lesion at the tip of the appendix and proceeded to perform a laparoscopic appendectomy. The lesion revealed a carcinoid tumor of the appendix.  (+info)

Molecular genetic evidence supporting the clonality and appendiceal origin of Pseudomyxoma peritonei in women. (2/160)

Pseudomyxoma peritonei (PMP) is a poorly understood condition characterized by mucinous ascites and multifocal peritoneal mucinous tumors. Women with PMP often have mucinous tumors involving both the appendix and the ovaries. Several previous histopathological and immunohistochemical studies of PMP have suggested that most, if not all, cases of PMP in women are derived from mucinous adenomas of the appendix rather than from primary ovarian tumors. A few studies of the molecular genetics of PMP have been recently reported. However, these studies analyzed only a small number of cases and some included a heterogeneous group of mucinous tumors, including both benign and malignant appendiceal and ovarian tumors. We analyzed K-ras mutations and allelic losses of chromosomes 18q, 17p, 5q, and 6q in a substantial number of morphologically uniform cases of PMP with synchronous ovarian and appendiceal tumors as well as in appendiceal mucinous adenomas (MAs) and ovarian mucinous tumors of low malignant potential (MLMPs) unassociated with PMP. Each of the 16 PMP cases (100%) analyzed demonstrated identical K-ras mutations in the appendiceal adenoma and corresponding synchronous ovarian tumor. K-ras mutations were identified in 11 of 16 (69%) appendiceal MAs unassociated with PMP and in 12 of 16 (75%) ovarian MLMPs unassociated with PMP. Two PMP cases showed identical allelic losses in the matched ovarian and appendiceal tumors. A discordant pattern of allelic loss between the ovarian and appendiceal tumors at one or two of the loci tested was observed in six PMP cases. In all but one instance, LOH was observed in the ovarian tumor, whereas both alleles were retained in the matched appendiceal lesion, suggesting tumor progression in a secondary (metastatic) site. Our findings strongly support the conclusion that mucinous tumors involving the appendix and ovaries in women with PMP are clonal and derived from a single site, most likely the appendix.  (+info)

Morphological-histochemical study of intestinal carcinoids and K-ras mutation analysis in appendiceal carcinoids. (3/160)

Intestinal carcinoids are potentially malignant neoplasms. Their histogenesis and pathogenesis are currently uncertain. The morphological and histochemical characteristics of twenty intestinal carcinoids are studied. The primary sites of three mucin-producing tumors were examined by electron microscope. Furthermore 11 appendiceal carcinoids were analysed by the polymerase chain reaction (PCR) for the detection of ras and p53 point mutations. Microscopically all carcinoids were of mixed type. Focal mucin production was evident in three carcinoids that metastasised to regional lymph nodes. HID-Alcian blue staining proved that mucin in both primary and secondary foci did not belong to the sulphated group. The secretory granules and mucin droplets found in a single neoplastic cell suggest that carcinoids of the small intestine and some of the appendix arise from the endoderm. Neither ras nor p53 mutations were detected. It seems that ras oncogenes are probably not involved in the pathogenesis of appendiceal carcinoids.  (+info)

Malignant mesothelioma eight years after a diagnosis of atypical mesothelial hyperplasia. (4/160)

The separation of mesothelial hyperplasia from early malignant mesothelioma remains one of the most difficult problems in histopathology. Inconclusive cases are termed "atypical mesothelial hyperplasia" and treated expectantly. A 49 year old male pipeline engineer was diagnosed as having atypical mesothelial hyperplasia in appendiceal serosa by the US-Canadian Mesothelioma Panel. Eight years later, he developed overtly malignant peritoneal and pleural mesothelioma. In hindsight, histological similarities between the diffuse malignant mesothelioma and the atypical mesothelial proliferation suggested malignancy from the outset. The most important of these features were the degree of mesothelial proliferation, micronodularity, architectural complexity, superficial invasion, uniform mild cytological atypia, and the absence of a clinical cause for a benign mesothelial proliferation. Ancillary investigations including immunohistochemistry were of no benefit in determining whether the atypical mesothelial hyperplasia was benign or malignant. Careful histological examination remains the mainstay of the diagnosis of early mesothelioma.  (+info)

The coexistence of low-grade mucinous neoplasms of the appendix and appendiceal diverticula: a possible role in the pathogenesis of pseudomyxoma peritonei. (5/160)

We examined 38 appendectomies with diagnoses of mucocele, diverticulum, or adenoma to study the coincidence of appendiceal diverticula and appendiceal low-grade mucinous neoplasms and to examine the possible role of diverticula in the pathogenesis of pseudomyxoma peritonei. Invasive adenocarcinomas and retention cysts were excluded (six cases). Cases were classified as adenomas or mucinous tumors of unknown malignant potential, with or without diverticula. Medical records were reviewed for multiple parameters, including presenting symptoms, presence of pseudomyxoma peritonei, and presence of associated malignancies. Binomial statistics were used to calculate the probability that the observed prevalence of low-grade mucinous neoplasms and diverticula together was significantly different from the expected prevalence of diverticula or low-grade mucinous neoplasms alone, using historical controls from the literature. Twenty-five percent of the total cases (8 of 32) contained both a low-grade mucinous neoplasm (7 cystadenomas and 1 mucinous tumor of unknown malignant potential) and a diverticulum. Thus, 8 of 19 low-grade mucinous neoplasms (42%) were associated with diverticula. Of the appendices with both low-grade mucinous neoplasms and diverticula, three contained dissecting acellular mucin within the appendiceal wall, four showed diverticular perforation, and one had pseudomyxoma peritonei associated with the ruptured diverticulum. A significant percentage (P < .001) of cases contained low-grade mucinous neoplasms and diverticula together. The case of coexistent low-grade mucinous neoplasm, diverticulum, and pseudomyxoma peritonei suggests that diverticula could play a role in the pathogenesis of pseudomyxoma peritonei. This could occur either by involvement of preexisting diverticula by the neoplasm or by distention of the appendiceal lumen by mucin, leading to increased intraluminal pressure and subsequent diverticulum formation at a weak area in the wall. Either mechanism might allow low-grade mucinous neoplasms to penetrate the appendiceal wall more easily.  (+info)

Pyomyositis mimicking right iliac fossa mass: review of the literature. (6/160)

Pyomyositis is a pyogenic infection of skeletal muscle. Its incidence in temperate countries though low is rising. Most cases from the temperate region involve immuno-compromised patients. The onset is usually insidious with progression to large purulent collections. Because of its low incidence in temperate countries, it is often initially misdiagnosed. A high index of suspicion with appropriate imaging techniques, aggressive surgical intervention and adjunctive antibiotic therapy are the keys to prompt resolution. A case of pyomyositis mimicking right iliac fossa (RIF) mass is described with a review of the literature.  (+info)

Carcinoid syndrome symposium on treatment modalities for gastrointestinal carcinoid tumours: symposium summary. (7/160)

OBJECTIVE: To develop a collaborative approach for the treatment of gastrointestinal carcinoid tumours and carcinoid syndrome. PARTICIPANTS: Leaders in the medical, endocrine, radiologic and surgical treatment of carcinoid disease were selected to present papers at the Carcinoid Syndrome Symposium on Treatment Modalities for Gastrointestinal Carcinoid Tumours and participate in the workshop that followed. EVIDENCE: A multidisciplinary symposium with experts in the field of carcinoid syndrome was organized at the University of Calgary. Data presented, participation of the attendees and a review of the literature were used in the workshop to develop a collaborative approach to the management of carcinoid tumours. BENEFITS: Carcinoid tumours are rare and few centres have large experiences in their treatment. Before the development of this collaboration, patients with carcinoid tumours received a unidisciplinary approach depending on referral patterns. The development of a multidisciplinary neuroendocrine clinic helped to unify the approach to these patients, yet a consensus on the treatment of carcinoid tumours was lacking. The expertise at the symposium allowed for consensus and the development of treatment algorithms, including biochemical screening, radiographic localization and surgical intervention, for gastrointestinal carcinoid tumours. The role of medical and hormonal therapy after cytoreducion is presented. RECOMMENDATION: Patients with carcinoid tumours require a multidisciplinary approach to their care.  (+info)

N2 - Appendiceal adenocarcinomas are uncommon, and the genetic alterations present in these tumors are not well characterized. We studied genetic alterations including loss of chromosome 18q (location of DCC, DPC4, and JV-18 genes), and mutations of the DPC4 (SMAD4) and β-catenin genes in 28 appendiceal adenocarcinomas, consisting of 17 mucinous and 11 nonmucinous carcinomas. Chromosome 18q loss was present in 57% (12/21) of appendiceal carcinomas including 54% (7/13) of mucinous and 63% (5/8) of nonmucinous carcinomas. Mutation of the DPC4 gene was present in 14% (three of 22) of the carcinomas occurring in one tumor with chromosome 18q loss and in two with unassessed ...

We hypothesized that conditional survival provides an informative metric that allows patients better understanding of their disease. Methods: Using the Surveillance, Epidemiology and End Results database, patients with appendiceal adenocarcinoma from 1988 to 2012 were included. Actuarial Life table analyses and Kaplan-Meier curves were used for statistical inference. Results: Of 5,952 patients, the median age was 60 years (IQR 50-72) and 52 % were female. Histologies included were adenocarcinoma (NOS 37 %), mucinous adenocarcinoma (MA 53 %), and signet ring cell (SRC 10 ...
BACKGROUND:Low-grade appendiceal mucinous neoplasms (LAMNs) are cytologically low-grade tumors of the appendix and are a frequent cause of pseudomyxoma peritonei. They can become a diagnostic challenge when they metastasize to the ovaries, where they may mimic primary ovarian mucinous tumors. CASE REPORT:We report the case of a patient with very large bilateral ovarian mucinous tumors and a concurrent minute LAMN incidentally discovered in a grossly normal appendix. A primary ovarian tumor was suspected, but histological analysis of the ovaries suggested an appendiceal origin. Immunohistochemical studies were not informative and a consensus regarding the source of the ovarian tumors could not be reached within our department. Subsequent next-generation sequencing of tumors from the right ovary, left ovary, appendix, and matched normal tissue demonstrated identical somatic point mutations in KRAS and GNAS present in all tumors. The patient was diagnosed with metastatic LAMN and did not receive further
High-grade appendiceal mucinous neoplasms (HAMN) are rare mucinous tumours of the appendix showing high-grade cytologic atypia, c.f. low-grade appendiceal mucinous neoplasms (LAMN). The distinction between both LAMN and HAMN is done on a histolog...
The response rates, PFS, and OS noted in this study are nearly identical to those seen in metastatic CRC, and support consideration of these regimens for advanced appendiceal adenocarcinoma in clinical practice. This recommendation is also consistent with current NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Colon Cancer.12 In a large trial by Saltz et al,13 1401 patients were randomly assigned to XELOX versus FOLFOX and then to bevacizumab versus placebo. Median PFS was 9.4 months in the bevacizumab group and 8.0 months in the placebo group. Median OS was 21.3 months in the bevacizumab arm and 19.9 months in the placebo arm. Response rates were similar at 38% in both arms. These results are similar to those described in this analysis of treated patients with appendiceal carcinoma.. The present efficacy results are also in line with single-center experiences in the more modern era of chemotherapy. A retrospective review from MD Anderson analyzed 78 patients with either ...
Although both appendiceal tumor and intestinal endometriosis have been reported as rare causes of abdominal pain, the coexistence of appendiceal mucinous neoplasm and ileal endometriosis has not previously been reported. A 41-year-old Japanese woman presented with a positive fecal occult blood test and a 3-year history of menstruation-related lower abdominal pain. A colonoscopy demonstrated extrinsic compression of the cecum, suggesting a mass arising from the appendix or adjacent structures. Abdominal imaging showed a 6-cm cystic mass with intraluminal thick fluids originating from the appendix. At ileocecal resection for an appendiceal tumor, a 2-cm mass in the terminal ileum was incidentally found, which was included in the surgical specimen. Microscopic examination confirmed a diagnosis of a mucinous neoplasm of the appendix with endometriosis of the terminal ileum. To avoid urgent surgery for subsequent serious events associated with disease progression, appendiceal tumor and intestinal
CASE REPORT: We present a case of low-grade appendiceal mucinous neoplasm with peritoneal dissemination, in which single-port laparoscopic approach of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy was completed through a 5.5-cm incision. A 35-year-old man with no medical illness underwent laparoscopic appendectomy for acute appendicitis 3 months earlier. Postoperative surgical pathology reported a low-grade appendiceal mucinous neoplasm with positive margin. After complete assessment and Tumor Board discussion, the patient was scheduled for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. A single gel port access was inserted through a 5.5-cm peri-umbilical incision. The Peritoneal Cancer Index score was 4, and the decision was made to proceed with partial cecectomy, omentectomy, peritonectomy, and hyperthermic intraperitoneal chemotherapy with the Sugarbaker mitomycin C-based regimen. Postoperative care was carried out following the Enhanced Recovery ...

The grading and staging of appendiceal mucinous neoplasms is challenging and fraught with terminology problems, but has critical prognostic and therapeutic implications. We utilized a small case series to examine the grading and staging systems of appendiceal mucinous neoplasms and outline the evidence for the new systems proposed in the upcoming 8th edition of the American Joint Committee on Cancer (AJCC) Staging Manual. We reviewed 33 cases of appendiceal mucinous neoplasms with available clinical follow-up data, 6 of which were widely disseminated in the peritoneum ...
Appendiceal cancer is a relatively rare condition that causes rapidly dividing cells to form malignant tumors within the appendix, a pouch-like tube attached to the first section of the large intestine.
Appendiceal mucocele is a rare entity that can present in a variety of ways. The incidence is estimated to be 0.2% to 0.3% of appendectomy specimens. Appendiceal mucocele refers to dilatation of the appendiceal lumen by an abnormal accumulation of mucus. It can be confused radiologically with an ovarian teratoma, which may prove to be a diagnostic challenge. Early diagnosis and prompt treatment is important to avoid unintended rupture and the development of pseudomyxoma peritonei. The diagnosis of mucocele of the appendix as well as other appendiceal neoplasms should be considered by the gynecologist in the differential diagnosis of a right-sided adnexal tumor. We report a case of appendiceal mucocele mistaken for ovarian teratoma in a 59-year-old women ...
10/01/2012. Appendiceal carcinoma, pseudomyxoma peritonei (PMP)* and other peritoneal surface malignancies are rare and, sadly, all too often misdiagnosed or poorly managed. Just ask Joseph Laureanno, a 53-year-old sales executive from Lowell.. Id been having some discomfort in my lower right abdomen, he recalls. So when I went for my regular wellness checkup with my PCP, he sent me for a CT, thinking I might have a gallstone.. Based on the CT, however, they thought I might need an appendectomy but were concerned about the fluid they saw in my abdomen, he continues. They suggested I go by ambulance to the ER at a Boston hospital. They found a small growth they called a mucocele on my appendix but commented that the fluid was not a concern because it didnt appear to be infected. So after 10 hours, they sent me home with the recommendation to get back to my PCP for a referral to see a gastroenterologist. There was no great sense of urgency.. His PCP referred Laureanno to Lauri Welch, BS, ...

I have been diagnosed with stage IV appendiceal adenocarcinoma and had surgery to remove appendix, part of my colon, and arachus in February of this year. The tumors have metasasized to the right pelvic sidewall and I am being treated with Oxaliplatin IV every 3 weeks followed by 2000 mg Xeloda (capecitabine) twice daily with meals for 14 days, followed by 7 days off treatment. Because this a relatively rare type of caner (about 1 in 10000 cases), I am being treated as a colo-rectal patient.. My question regards possible drug interaction with serum triglyceride blood tests. During my week off treatment, my reading was 209, which is slightly elevated from a normal range of 50-150. Towards the end of my next treatment cycle, the readings had shot up to 1167. Three weeks later, after being off Xeloda for a week, my readings had gone down to 889.. My oncologist says that he has been unable to find anything that shows a correlation or lack of one between either my IV or Xeloda and increased ...
One of the more interesting aspects of small bowel adenocarcinoma is its rarity in comparison to large intestine adenocarcinoma. Even though the small intestine represents approximately 70% to 80% of the length and over 90% of the surface area of the alimentary tract, the incidence of small bowel adenocarcinoma is 30-fold less than the incidence of colon adenocarcinoma. Numerous theories have been proposed to explain the small intestines relative protection from the development of carcinoma. Proposed protective factors have centered on two concepts. First, the rapid turnover time of small intestinal cells results in epithelial cell shedding prior to the necessary acquisition of multiple genetic defects. Second, the small bowels exposure to the carcinogenic components of our diet are limited due to rapid small bowel transit time, the lack of bacterial degradation activity that occurs in the small bowel, and the relatively dilute, alkaline environment of the small bowel ...

Ms. OFlaherty has clearly read the textbook chapter on appendicitis. Her pain developed over 36 hours and began with visceral (appendiceal) irritation that she perceived as midline discomfort. As her appendiceal inflammation became transmural, she stimulated somatic peritoneal nerves sufficient to cause RLQ pain but not sufficient to cause rebound. Rebound can be elicited by pressing very gently on the RLQ and then releasing the pressure. When the inflamed visceral and parietal peritoneum rub against each other, this causes discomfort. If the patient winces during this procedure, he or she has an inflamed peritoneal surface.. As with all patients, the history and physical examination can help you narrow the differential. For example, if this patient had recently eaten at an unfamiliar ethnic restaurant and now had raging diarrhea, you would think more of gastroenteritis. If she had a cervical discharge and exquisite tenderness with cervical motion (chandelier sign), you would think of pelvic ...

Goblet cell carcinoid tumor is a rare clinical entity which is usually diagnosed either as acute appendicitis or advanced cancer. Its main characteristic is that the histological findings are between those of adenocarcinoma and typical carcinoid tumor of the appendix. Goblet cell carcinoid tumors appear almost exclusively in the appendix, and prognosis depends mainly on the stage and the subtype of the histological classification. We report three cases of goblet cell carcinoid tumor in the appendix with different clinical presentation and evolution: a 60-year-old male admitted to the emergency room with acute abdominal pain, diagnosed with acute appendicitis and treated with laparoscopic appendectomy; a 65-year-old male undergoing right hemicolectomy to remove a cecal adenoma, with a goblet cell carcinoid tumor found incidentally in the surgical specimen; and a 77-year-old male with acute appendicitis.

Primary adenocarcinoma of the appendix is a rare disease in clinical practice. Moreover, primary adenocarcinoma of the appendix in the pediatric age group is even rarer with very little cases being published. Here, we report a case of primary adenocarcinoma of the appendix with local invasion into adjacent organs in a child who was initially diagnosed as having an acute appendicitis. A 13-year-old girl presented with abdominal pain of 3-month duration. Imaging study showed a mass including the fecalith that occupied her pelvic and right lower abdominal cavity. Drainage of the abscess and appendectomy were performed by the preoperative diagnosis of an acute appendicitis with an appendiceal mass. Postoperative histopathological examinations revealed the appendiceal adenocarcinoma. She then received the whole mass resection, ileocecal resection with lymph node dissection. The masses were tightly adherent with infiltration into the sigmoid colon, uterus, and right ovary. These organs were all dissected, and
The vermiform appendix is a blind-ended tube that projects from the cecum. The term vermiform comes from Latin and it means worm-shaped. Thus, the vermiform appendix is a projection that is worm-shaped connected to the cecum. The average size of a human vermiform appendix is about 9 cm in length whereas the diameter is generally between 7 and 8 mm. It is often found in the lower right quadrant of the abdomen. Its position corresponds to the so-called McBurneys point. For herbivores, the vermiform appendix is essential since it is responsible for the breaking down of cellulose present in the cell wall of plants. In humans and other animals, it became a redundant process since it has no particular daily function. Nevertheless, it is postulated to be associated with maintaining gut flora, particularly during a recovery from diarrhea.1 ...
Unlike previous studies, the CODA study was designed as a pragmatic trial and included patients with faecolith and only patients with radiologically confirmed appendicitis. The primary outcome aimed at the patient experience. While antibiotic treatment was found to be non-inferior to surgery, the same conclusion does not apply to patients with faecolith. The diagnosis of appendicular fecolith usually requires a CT scan which is not considered as a routine practice in the UK unlike the USA and Europe.. The risk of missing appendiceal neoplasms with the antibiotic approach is important. Subsequent investigation to exclude cancer in some patients and the financial burden from readmission and repeated investigations have not been investigated yet.. Finally, the results from CODA trial support the conservative management of acute appendicitis during the COVID pandemic and should be considered in consenting patients for appendicectomy.. ...
Pseudomyxoma peritonei (PMP) is a clinical condition caused by cancerous cells (mucinous adenocarcinoma) that produce abundant mucin or gelatinous ascites. The tumors cause fibrosis of tissues and impede digestion or organ function, and if left untreated, the tumors and mucin they produce will fill the abdominal cavity. This will result in compression of organs and will destroy the function of colon, small intestine, stomach, or other organs. Prognosis with treatment in many cases is optimistic, but the disease is lethal if untreated, with death by cachexia, bowel obstruction, or other types of complications. This disease is most commonly caused by an appendiceal primary cancer (cancer of the appendix); mucinous tumors of the ovary have also been implicated, although in most cases ovarian involvement is favored to be a metastasis from an appendiceal or other gastrointestinal source. Disease is typically classified as low- or high-grade (with signet ring cells). When disease presents with ...

ON THIS PAGE: You will find information about the number of people who are diagnosed with appendix cancer each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors. Use the menu to see other pages.. Primary appendix cancer is cancer that starts in the appendix. This is uncommon, accounting for about 0.5% of all tumors that start in the GI tract.. The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate for people with appendix cancer depends on many factors, including the stage and grade of disease at time of diagnosis, type of appendiceal tumor (see Types of Appendix Tumors in the Introduction section), and size.. For grade 1 or grade 2 GI neuroendocrine tumors overall, a category that includes neuroendocrine tumor of the appendix, the 5-year survival is between 67% to 97%, depending on the size of the tumor and ...
Misfolded α-synuclein is a pathological hallmark of Parkinsons disease (PD). Killinger et al. now report that the human appendix contains an abundance of misfolded α-synuclein and that removal of the appendix decreased the risk of developing PD. The appendix of both PD cases and healthy individuals contained abnormally cleaved and aggregated forms of α-synuclein, analogous to those found in postmortem brain tissue from patients with PD. Furthermore, α-synuclein derived from the appendix seeded rapid aggregation of recombinant α-synuclein in vitro. In two large-scale epidemiological studies, the authors demonstrated that an appendectomy occurring decades prior reduced the risk of developing PD, suggesting that the appendix may be implicated in PD initiation. ...
AIMS: The functional integration of the smooth muscle of enterocystoplasties into the detrusor muscle was investigated in an awake-rat cystometry model and in vitro.. METHODS: The upper fourth of the bladder was removed, and a detubularized appendiceal segment (7 x 7 mm), with preserved vasculature, was incorporated into the bladder. After 1 or 3 months, a catheter was fixed to the top of the bladders. After a 3-day recovery, cystometries were performed. In separate experiments, agonist and nerve-induced responses were evaluated on isolated bladder strips.. RESULTS: Cystometries revealed reduced basal pressure and micturition pressure in enterocystoplasty (ECP) bladders. Bladder capacity and micturition volume were increased. Threshold pressure (pressure immediately before micturition) was significantly lower at 1 month, but not at 3 months. Bladder compliance was significantly higher in the operated at 1 month but not at 3 months. Threshold tension did not differ between control and ...

The arterial blood supply, position and length of appendix were studied in 100 Indian (Uttar Pradesh region) cadavers. In 39% more than one appendicular artery was demonstrated. The retrocaecal and retrocolic positions of the appendix were by far the
The vermiform appendix is located in the right lower quadrant of abdomen (Williams et al, 1995, Sabiston et al, 2001). It is a narrow, worm shaped tube, arising from the posteromedial caecal wall, 2cms or less below the end of the ileum (Williams et al, 1995; Zinner et al, 1997). Its opening is occasionally guarded by a semicircular fold of mucous membrane knwn as the valve of Gerlach (Singh, 1999). The appendix is usually located at the junction of the taeniae,found on the surface of the caecum (Williams et al, 1995; Sabiston et al, 2001 and Schwartz at al, 1999). Its length varies from 2-20 cms, with an average length of 9cms (Williams et al, 1995, Buschard. & Kjaeldgaurd, 1973). The attachment of the base of the appendix to the caecum remains constant, whereas the tip can be found in a retrocaecal, pelvic, subcaecal, preileal and post-ileal positions (Williams et al, 1995; Sabiston et al, 2001; Schwartz et al, 1999). It is connected by a short mesoappendix to the lower part of the ileal ...
Authors: Kaul, Dhananjaya K. , Baez, Silvio , Nagel, Ronald L. Article Type: Research Article Abstract: Experiments were carried out to determine flow properties of oxygenated normal and abnormal blood (HbAA, HbAS, HbSS, HbSC, HbAC, HbCC and rat) using isolated artificially perfused rat mesoappendix microvasculature. Changes in arterial perfusion pressure (Ppa) and venous outflow (Fv) were recorded after the infusion of blood, and peripheral resistance unit (PRU) was calculated. In a series of experiments, pressure-flow recovery time (Tpf) was determined, and microphotography was done in selected experiments. Viscometry was carried out at a shear rate of 230 sec−1 In the perfused mesoappendix, HbSS and HbSC blood resulted in higher PRU as well as increase in …Tpf when compared to those for HbCC blood, though the latter was more viscous. Evidence is presented regarding the trapping and fragmentation of the irreversibly sickled cells (ISC) in microvasculature. The possible role of certain ...
Some mammals have an appendix connected to their cecum-the first section of the large intestine-but others dont. How and when did that once-mysterious organ originate?. Midwestern University Anatomist Heather Smith led an extensive study of 533 mammal species, looking for clues to appendix evolution. Three of the teams scientific observations contradict evolutionary expectations.. This body part bears a wrong reputation as a useless leftover from supposed evolutionary ancestors that once used it. Now science has revealed plenty of valuable activities the appendix performs. It harbors microbes that help the gut recover after traumatic times. Lymphoid tissue also lives there, showing the appendixs integration with the immune system.. Evolution suggests three expectations for appendix origins. First, if the supposed ancestor of only one kind of mammal evolved an appendix, then only members of that kind should have inherited the trait and still have it today. Similarly, if the supposed ...
Thats interesting: the only groups that have an appendix are the Glires (rodents and rabbits), primates, monotremes, and some marsupials. Theres definitely a pattern to the distribution: it is not the case that the appendix is a random glitch in the organization of the gut, but is maintained consistently in some lineages for as long as 80 million years, and is consistently lost in others.. The data are useful to have and provide considerable food for thought; where I disagree with the authors is in the interpretation of that data. I dont think purely morphological data give us enough information to resolve the issues they bring up.. Heres what the authors conclude from that distribution. The most parsimonious explanation is that the ancestral state of mammals was to lack an appendix, so that the majority of extant mammals are exhibiting the primitive, appendix-less state. The appendix then independently evolved 2-4 times, with the lineages that acquired it also marked by frequent secondary ...
Helpful, trusted answers from doctors: Dr. Raff on why did the ct not show my appendix: will not see rectum but most of large intestine will be seen
Now here comes the screwed up part! About 30 minutes later (after I already wrote an e-mail to Romys thesis adviser that he couldnt go into work because he will be getting his appendix removed that day), another doctor comes in. This doctor said something we could not believe. He asked us to confirm that Romy had a CAT scan taken for the same reason one year ago in February. We said yes. Then he kind of smiled and said that the previous doctor had looked at the February 2012 CAT scan by mistake and ordered the puss and appendix removal based on the FEBRUARY scan!!! It was only after they realized they were looking at the old CAT scan (which was supposedly just constipation!?), that they recognized how bad Romy was that day. The new CAT scan revealed a badly ruptured appendix. His appendix was ruptured so badly that they canceled the puss suction and the appendix removal. All the doctor could say was that the new CAT scan was very messed up. Puss, scar tissue, and fluid everywhere. He said ...

A surgeon who accidentally removed a womans ovary instead of her appendix has been struck off after being branded a danger to patients.. Dr Lawal Haruna, 59, botched up three operations over the course of two years.. Patient B was treated by him when she was admitted for abdominal pain while he was working for Sheffield Teaching Hospitals Trust in Sheffield, South Yorkshire.. During the operation, one of her ovaries was removed leaving her appendix - which was causing her great pain - in situ. A tribunal heard how it was lucky she was not of child-bearing age as it could have affected her fertility.. Dr Haruna botched up two further operations - mistaking a lump of fat for an appendix in one case and a skin tag for a cyst in another.. Colleagues described the operations as poorly executed and never events.. Read more in the Daily Mail.. ...
Chimpanzees and other apes are our closest living relatives, and they all have an appendix that looks a lot like ours. So its reasonable to infer that our common ancestor 30 million years ago also had one.. But when Dr. Fisher researched the guts of other primates, the picture got blurrier. In some cases its absent, but in other cases its spot-on looking like a human appendix, she said.. Some primate species fall somewhere in between these two extremes, with just a narrowed tip forming on the cecum. Dr. Fisher suspects that the appendix evolved several times in primates, but she cannot say what conditions favored its evolution. Since the data is so poor, I think any trend would just be a lucky happenstance, she said.. Still, I wondered how such a dangerous and disposable organ could survive over evolutionary time. We consider it maladaptive because we want to live to a very old age, Dr. Fisher said. But from a strictly Darwinian view, it might not be.. Imagine a trait that helps an ...

Bowel cancer also known as colorectal cancer, is defined as a condition of the abnormal proliferation of cells in the colon, rectum, or vermiform appendix. Bowl is divided in 2 parts, the first part of the bowel, the small bowl, is involved with the digestion and absorption of food. The 2nd part, the large bowel which consist the the colon and rectum, is involved in absorption of water from the small bowel contents and broken down of certain materials in the feces into substances of which some of them to be re absorbed and reused by the body. Bowel cancer is relatively very common and slowly growing and progress cancer and in predictable way ...
