Observations on some additional abnormalities in situs inversus viscerum. (1/27)

The abnormal findings in a case of Situs inversus totalis are described. The duodenum was placed abnormally and retained its primitive mesentery. The proximal 22 in of jejunum were retroperitoneal. The attachment of the root of the mesentery to the posterior abdominal wall had a 7-shaped appearance, and there was a partial failure of the primitive mesocolon to adhere to the posterior abdominal wall. The common hepatic artery arose from the superior meseneric artery, which also provided a branch to the proximal jejunal loop. The right vagus nerve was found anterior to the oesophagus at the oesophageal hiatus in the diaphragm, and the left vagus was posterior. A double ureter was present on the right side. The findings are discussed in relation to mid-gut development.  (+info)

Solid and papillary epithelial neoplasm arising in heterotopic pancreatic tissue of the mesocolon. (2/27)

AIM: Solid and papillary epithelial neoplasm (SPEN) is an uncommon pancreatic tumour. Very rarely it has also been described outside the pancreas, usually arising from heterotopic pancreatic tissue. This report summarises all the published extrapancreatic SPENs and documents the sixth such case arising from heterotopic pancreatic tissue of the transverse mesocolon in a 15 year old girl. METHODS/RESULTS: Histological and immunohistochemical examination revealed typical papillary and solid areas composed of columnar, cuboidal, and round cells, which were focally positive for vimentin, cytokeratin, neurone specific enolase, carcinoembryonic antigen, alpha1-antitrypsin, alpha1-antichymotrypsin, and negative for neuroendocrine markers (neurofilament, PGP 9.5, chromogranin A, synaptophysin, and S100), p53, and oestrogen and progesterone receptors. Electron microscopy showed scant zymogen but no neurosecretory granules. In agreement with the flow cytometric result s of diploidy, comparative genomic hybridisation (CGH) did not reveal loss or gain of genetic material, and the in situ hybridisation analysis of the RB1 and p53 genes revealed no abnormality in the 13q and 17p arms. CONCLUSIONS: Immunohistochemical and electron microscopic data support exocrine differentiation. The CGH and the flow cytometric results suggest a subtle, yet unknown genetic change, rather than a large genetic alteration. RB1 and p53 in situ hybridisation ruled out the role of deletion at these sites in the pathogenesis of SPEN. Interestingly, review of the published and the present heterotopic pancreatic SPENs identified the mesocolon as the most common anatomical site (four of six), despite the very rare occurrence of ectopic pancreatic tissue at this site.  (+info)

Leiomyosarcoma of the mesocolon--a case report. (3/27)

Retroperitoneal leiomyosarcomas including those arising from the mesentery are rare. These account for 5.8% of all soft tissue sarcomas. Most of these tumors present in late life with female preponderance. Diagnosing these tumors at an early stage is difficult due to their location. Hence, most of them attain large sizes with metastases to distant sites at the time of diagnosis. We report a case of leiomyosarcoma arising from the sigmoid mesocolon due to it's rarity and unusual clinical presentation.  (+info)

Rare complications of endoscopic retrograde cholangiopancreatography: two case reports. (4/27)

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a diagnostic procedure with several known risks. We present two rarely reported complications of ERCP and sphincterotomy: transverse mesocolon disruption with ischemic colitis and splenic rupture. RESULTS: The first patient, a 54-year-old female, presented one day following ERCP and stent revision for pancreas divisum. She presented with hypotension and abdominal distention. An abdominal computed tomography (CT) showed a ruptured spleen, which was confirmed on laparotomy. She had a complicated postoperative course and died of multiple organ failure. The second patient is a 56-year-old female who presented five days after ERCP and sphincterotomy with abdominal pain, abdominal wall ecchymosis, and decreasing hematocrit. Her evaluation included hospital admission and abdominal CT scan, which showed free fluid and a large hematoma in the transverse mesocolon. These findings were confirmed on laparotomy and a devascularized segment of bowel was resected. CONCLUSION: Only 6 cases of ERCP-related splenic injury have been reported in the literature. One additional report is available of a fatal splenic artery injury. No previous reports exist of a mesenteric hematoma resulting in bowel devascularization. Prompt evaluation and awareness of potential complications should help capture potentially life-threatening sequelae of ERCP.  (+info)

Conclusions from a study of venous invasion in stage IV colorectal adenocarcinoma. (5/27)

AIMS: Venous invasion is an established predictor of prognosis in colorectal cancer (CRC). The reported incidence of venous invasion in CRC specimens varies between 10% and 89.5%, mainly as a result of interobserver variability and differences in specimen processing (for example, staining with haematoxylin and eosin (H+E) alone versus the addition of an elastic fibre stain). This study was performed with three purposes in mind, namely: (1) To assess and compare the incidence of venous invasion diagnosed on H+E stained tissue versus tissue stained with both H+E and an elastic fibre stain. (2) To estimate the inherent false negative rate associated with the diagnosis of venous invasion by histopathological evaluation of resected CRC specimens. (3) To compare the resulting data regarding incidence, quantity, site, and type of venous invasion to the pertinent literature. METHODS: Venous invasion was assessed on sections from 81 CRCs resected from patients with synchronous distant metastases (hepatic and non-hepatic). Only stage IV tumours were studied for the following reasons: (1) it can be assumed that in all patients with distant haematogenous metastases venous invasion had occurred, thus enabling the false negative rate to be calculated; (2) there can be no dispute about the clinical relevance of the various characteristics of venous invasion identified in the tumours of patients with synchronous distant haematogenous metastases; and (3) to eliminate the effect of variance in tumour stage on the incidence of venous invasion. Initially, H+E stained sections were studied for venous invasion. Sections that were negative or questionable with regard to venous invasion were then stained with an elastic fibre stain, and a second search for venous invasion was carried out. Venous invasion was characterised by incidence, quantity, type, and site. The chi(2) test for independence was used to compare the incidence of venous invasion in colonic versus rectal and rectosigmoid primary tumours, and in patients with hepatic versus non-hepatic metastases. RESULTS: Venous invasion was identified in 42 (51.9%) (of the 81 specimens on H+E stained sections. The addition of the elastic fibre stain enabled the diagnosis of venous invasion in 15 (38.5%) of the remaining 39 specimens, increasing the overall incidence to 57 of 81 cases (70.4%). Of the 57 positive specimens, venous invasion was minimal in 27 (47.4%), intermediate in five, (8.8%) and massive in 25 (43.9%). Only intramural veins were involved in 18 (31.6%), only extramural veins in 26 (45.6%), and both intramural and extramural veins in 13 (22.8%) of the 57 positive specimens. The filling type of venous invasion was found in 41 (71.9%), the floating type in 28 (49.1%), and the infiltrating type in six (10.5%) of the 57 positive specimens. There was no significant difference between the incidence of venous invasion in the colon (42 of 60; 70%) versus rectal and rectosigmoid tumours (15 of 21; 71.4%; p = 0.8539), nor in the incidence of venous invasion in patients with hepatic (49 of 70; 70%) versus non-hepatic (eight of 11; 72.7%) metastases (p = 0.9018). CONCLUSIONS: The addition of an elastic fibre stain enables the identification of venous invasion in a considerable proportion of sections from CRC tumours that are falsely negative for venous invasion on H+E stain alone. The inherent chance of missing venous invasion on histopathological evaluation of CRC tumours stained with H+E and elastic fibre stains is at least 10.5%, and may be as high as 29.6%. In a large proportion of stage IV CRCs, despite the presence of synchronous distant metastases, only a minimal extent of venous invasion (that is, one to two involved veins) is demonstrable in the primary tumour. This suggests that only minimal venous invasion is required for the seeding of clinically relevant haematogenous metastases, and emphasises the careful, dedicated search for venous invasion that is required from the pathologist. Although extramural venous invasion was predominant in stage IV CRCs, in a considerable proportion of tumours (about a third) only intramural venous invasion was found. This suggests that intramural venous invasion may also seed clinically relevant haematogenous metastases, and should therefore also be considered as an indicator of poor prognosis.  (+info)

Delayed gastric emptying after Roux-en-Y due to four types of partial obstruction. (6/27)

Partial obstruction was the cause of delayed gastric emptying in 12 patients after a Roux-en-Y gastrojejunostomy in a consecutive personal series of 42 patients between 1975 and 1989. Four types of obstruction were identified. Type I was due to a kinked loop of jejunum where it passed through the mesocolon. Type II had the anastomosis too high on the gastric pouch, type III was due to an obstructing marginal ulcer, and type IV had a pouchlike deformity develop in the upper jejunum at the anastomosis that gradually compressed the outflow tract. No patient had stenosis of the anastomosis. The upper gastrointestinal (GI) series plus nuclear studies of the liquid and solid phase gastric emptying provided evidence of the presence and degree of delayed gastric emptying but not the site or cause of the obstruction. Upper GI endoscopy provided precise evidence of the site of the partial obstruction, its anatomic nature, and the presence of a bezoar or marginal ulcer. Of the 42 patients, 4 had surgical correction, and in 6 patients the obstruction was relieved by endoscopic manipulation; all patients have been relieved of their symptoms. Partial obstruction was the only cause of delayed gastric emptying in this series, and contrary to recent reports, no patient required a total or near total gastrectomy.  (+info)

Primary intraabdominal synovial sarcoma: a case report. (7/27)

The authors report a case of intra-abdominal synovial sarcoma in a 41-year-old female. The tumor, which had an unusual location, the ascending mesocolon, had a mono-phasic spindle cell pattern. Immunohistochemical positivity for the epithelial membrane antigen (EMA) and cytokeratin AE1/AE3 differentiated the lesion from other spindle cell sarcomas with similar histology. The pathological and clinical features of the entity are briefly discussed.  (+info)

The sigmoid mesocolon is the continuation of the descending mesocolon. It is the reflection of peritoneum which connects the sigmoid flexure with the posterior wall of the extreme lower portion of the abdominal cavity and with the posterior wall of the pelvic cavity. It extends from the termination of the descending colon in the iliac fossa, at the lateral border of the psoas major muscle, to the commencement of the rectum, opposite the middle portion of the sacrum. In following the line of attachment of the sigmoid mesocolon, it crosses the psoas major muscle and the iliac vessels near their bifurcation. After passing slightly to the right, to descend obliquely, it reaches almost to the floor of the pelvis. The whole of the sigmoid mesocolon is to the left of the median line. The width of the sigmoid mesocolon permits the greater portion of the sigmoid flexure, when distended, to occupy the pelvic cavity, and often to extend into the hypogastric region. The sigmoid arteries and the superior ...

Peritonitis is a life-threatening event that is often accompanied by bacteremia and sepsis syndrome (Chap. 325). The peritoneal cavity is large but is divided into compartments. The upper and lower peritoneal cavities are divided by the transverse mesocolon; the greater omentum extends from the transverse mesocolon and from the lower pole of the stomach to line the lower peritoneal cavity. The pancreas, duodenum, and ascending and descending colon are located in the anterior retroperitoneal space; the kidneys, ureters, and adrenals are found in the posterior retroperitoneal space. The other organs, including liver, stomach, gallbladder, spleen, jejunum, ileum, transverse and sigmoid colon, cecum, and appendix, are within the peritoneal cavity. The cavity is lined with a serous membrane that can serve as a conduit for fluids-a property exploited in peritoneal dialysis (Fig. 159-1). A small amount of serous fluid is normally present in the peritoneal space, with a protein content (consisting ...

Patients with lumbar-peritoneal shunts are left with two scars; a vertical scar down part of the lumbar of the spine, and a horizontal scar across the upper abdomen. A lumbar-peritoneal shunt is expected to remain in situ for the lifespan of the patient unless revisions or relocation of the shunt is required. In some cases the shunt has been removed completely, however this is very rare as it is difficult to determine when a patients condition has changed to enable them to be independent of the shunt and relapse of the condition can occur requiring the patient to undergo surgery for the placement of a shunt again..

D-r Evdoshenko V.V. and D-r Fedenko V.V. are performing an operation.. One of the complications after gastric shunting - Roux-en-Y gastric bypass- is a formation of the internal hernia near the window of mesocolon. This window is created for pulling the loop of Roux colon into the superior part of the abdomen. Closure of that window at the end of operation is compulsory. Nevertheless, the closure sometimes is not efficient, and the situation is complicated by development of the internal hernia. Clinically it is manifested by intermitting intestinal obstruction, that within some period of time will be progressing, and the total obstruction will take place later on. This operation demonstrates the situation when the small colon is almost completely shifted into the cavity of omentum bursa through mesocolon window. So, the small colon has been shifted into proper position, open defect is stitched by continuous suture. ...

The superior mesenteric artery gives off several named branches (Figure 39.1). They include the inferior pancreaticoduodenal artery, middle colic artery, right colic artery, ileocolic artery and intestinal arteries. The middle colic artery divides within the transverse mesocolon into a right branch and a left branch. Branches of these arteries supply the proximal two-thirds of the transverse colon. The ascending branch and descending branch of the right colic artery supply the ascending colon. Finally, the ileocolic artery, the terminal branch of the superior mesenteric artery, divides into the appendicular artery, anterior cecal artery, and posterior cecal artery. These arteries, together with the small branches to the ileum and ascending colon, supply the terminal portion of the ileum, cecum, vermiform appendix, and proximal part of the ascending colon..

Although gastric bypass surgery continues to grow in popularity for dramatic weight loss and considerable weight maintenance in the morbidly obese, there has been little attention given to the possible complications associated with these procedures. It is estimated that more than 10% of patients who undergo the Roux-en-Y procedure have undergone complications; the rate of complications involving the duodenal switch procedure have not been clearly established given that it is still a relatively new procedure. Both an upper GI series and CT examination are important in diagnosing and following up on post-operative complications. Our findings support those of the current literature to include six unusual complications which include the following: internal herniation through the small bowel mesentery, internal herniation through the transverse mesocolon, external herniation through the abdominal wall incision, enterocutaneous fistulas, Roux-en-Y configuration with anti-peristaltic inversion of the ...

Methods: We developed the SMA hanging technique (SHT) to facilitate central vascular ligation during PD. Briefly, SMA dissection was initiated using the supracolic anterior approach, followed by left-sided dissection. The SMA was taped under finger guidance immediately after right-sided dissection. The ligament of Treitz was detached from the SMA during left-sided dissection, facilitating adequate lymph node dissection while preserving the nerve plexus around the SMA. ...
Very rarely recovery has been reported without intervention. The safe rule to follow is operation in practically every case. The best incision is the median or paramedian. The perforation of the anterior wall of the stomach is readily recognized. The opening in the posterior wall is best sought for through the gastrocolic omentum just below the stomach. Pauchets approach, recommended by Eastman,14 is made through an opening in the mesocolon, the line of dissection passing just above the transverse colon. This frequently gives good access, but it is not recommended for general use, as repair work is more difficult when this technique is used. A ragged wound should be trimmed off rapidly before suture. The greatest difficulty in accomplishing a good closure of the stomach wall will be found with wounds involving the lesser curvature and those high up near the cardiac orifice. Gastroenterostomy should be avoided if possible, for a higher mortality results in the cases in which it is performed. ...

There is a large amount of high attenuation fluid within the anterior pararenal space on the right, extending down into the pelvis. At the level of the right renal vein, there appears to be disruption of the inferior vena cava, with surrounding hematoma. There is a questionable area of intraluminal thrombus just below this. The remainder of the inferior vena cava below this level, is markedly decreased in caliber, crescentic in shape and displaced to the left. Immediately above the iliac confluence, the IVC abruptly resumes a normal shape, but is moderately dilated. Both kidneys demonstrate normal enhancement and excretion.

Experts indicate that omitting LND could have advantages in terms of fewer complications and shorter OR time, thereby improving quality of life and reducing costs. Currently, it is unknown if these advantages will weigh up to the possible risks of omitting LND when a diagnostic test is not 100% accurate. Recently, two phase III trials were initiated where watchful waiting is compared with standard surgery for patients with complete response of the tumour and LNs after nCRT.23 24 In these trials, the importance of an accurate diagnostic test after nCRT is crucial as patients with (micro) LN metastases could easily be missed, resulting in unjustified omission of surgery. Results of these trials are therefore of high interest to evaluate the consequences of unjustified omission of surgery.. The implications of accurate LN staging after nCRT will likely have a greater impact than solely omitting LND. For example, surgical approaches with a limited LND, for example, transhiatal oesophagectomy, might ...

Near death, explained. New science is shedding light on what really happens during out-of-body experiences - with shocking results.. by Mario Beauregard. (This article was adapted from the new book Brain Wars, from Harper One.). In 1991, Atlanta-based singer and songwriter Pam Reynolds felt extremely dizzy, lost her ability to speak, and had difficulty moving her body. A CAT scan showed that she had a giant artery aneurysm-a grossly swollen blood vessel in the wall of her basilar artery, close to the brain stem. If it burst, which could happen at any moment, it would kill her. But the standard surgery to drain and repair it might kill her too.. With no other options, Pam turned to a last, desperate measure offered by neurosurgeon Robert Spetzler at the Barrow Neurological Institute in Phoenix, Arizona. Dr. Spetzler was a specialist and pioneer in hypothermic cardiac arrest-a daring surgical procedure nicknamed Operation Standstill. Spetzler would bring Pams body down to a temperature so ...
When I had my debulking surgery, I too had a portion of my large intestine removed (about one foot) and a bowel resection because the tumor had attached itself there. About a year or so after my surgery, I was admitted a couple of times to the hospital for a partial obstruction of the small intestine due to adhesions (scarring from the surgery). Perhaps that is what is going on with your mom. I experienced lots of constipation as a side effect of chemo. To deal with it, I started taking Miralax about two or so days before my next round of chemo and kept taking it for a couple of days after my round of chemo. I also tried to drink a lot of fluids and eat food with fiber, like apples. I was pretty tired during some of my chemo time but I still kept moving, even if it was only to walk around the yard, to keep the bowels moving. Wishing the best for your mom.. Kelly ...

Sclerosing mesenteritis is a rare chronic fibrosing inflammatory disease of ambiguous pathogenesis primarily diagnosed in late adult life while pediatric cases are very uncommon because children have mesenteric fat than adults [1-3]. It is a benign disorder mainly involving the small-bowel mesentery; however, mesocolon, peripancreatic region, omentum, pelvis or retroperitoneum may be also involved. Both mesenteric panniculitis and mesenteric lipodystrophy are considered to be histological variants of sclerosing mesenteritis [4]. Viswanathan and Murray reported one case and summarized another 16 pediatric cases from the literature and found that the average age at diagnosis in children was 6.5 years [2]. In our case, the lesion was extensive and involved small intestine, ascending mesocolon, omentum and peritoneum, leading to intractable bowel obstruction. Clinical symptoms are usually non-specific, including abdominal pain, anorexia, fatigue, weight loss, fever, abdominal mass, ascites, ...
The transverse colon is the longest and most movable part of the colon. It crosses the abdomen from the ascending colon at the hepatic or right colic flexure with a downward convexity to the descending colon where it curves sharply on itself beneath the lower end of the spleen forming the splenic or left colic flexure. In its course, it describes an arch, the concavity of which is directed backward and a little upward. Toward its splenic end there is often an abrupt U-shaped curve which may descend lower than the main curve. It is almost completely invested by peritoneum, and is connected to the inferior border of the pancreas by a large and wide duplicature of that membrane, the transverse mesocolon. It is in relation, by its upper surface, with the liver and gall-bladder, the greater curvature of the stomach, and the lower end of the spleen; by its under surface, with the small intestine; by its anterior surface, with the posterior layer of the greater omentum and the abdominal wall; its ...
superiorly and to the right. Palpate the underlying abdominal aorta and then remove the peritoneum that covers its surface. Identify the inferior mesenteric artery as it arises from the anterior aspect of the abdominal aorta at the level of the L3 vertebra (Figure 39.2). As the inferior mesenteric artery passes inferiorly and to the left, it gives off several principal branches. These include the left colic artery, several sigmoidal arteries, and the superior rectal artery, which is the terminal branch of the inferior mesenteric artery. The left colic artery divides into ascending branch and descending branch, which supply the distal one-third of the transverse colon and the descending colon. The sigmoidal arteries enter the root of the sigmoid mesocolon and supply the sigmoid colon. The superior rectal artery passes into the pelvic cavity and supplies the rectum and superior portion of the anal canal.. Links and References: ...

The ascending colon is the part of the colon located between the cecum and the transverse colon. The ascending colon is smaller in calibre than the cecum from where it starts. It passes upward, opposite the colic valve, to the under surface of the right lobe of the liver, on the right of the gall-bladder, where it is lodged in a shallow depression, the colic impression; here it bends abruptly forward and to the left, forming the right colic flexure (hepatic) where it becomes the transverse colon. It is retained in contact with the posterior wall of the abdomen by the peritoneum, which covers its anterior surface and sides, its posterior surface being connected by loose areolar tissue with the iliacus, quadratus lumborum, aponeurotic origin of transversus abdominis, and with the front of the lower and lateral part of the right kidney. Sometimes the peritoneum completely invests it and forms a distinct but narrow mesocolon. It is in relation, in front, with the convolutions of the ileum and the ...
The CIC-rearranged sarcoma is a very rare highly aggressive malignant soft tissue group of tumors. It has recently been described as highly aggressive soft tissue tumors of children and young adults sharing similar morphological features with the Ewing sarcoma. The digestive localization is exceptional. A 14-year-old male presented with a history of abdominal pain for 1 year, which increased in intensity over the last 2 months. Imaging findings showed a large heterogeneous mesenteric mass on the left flank of the abdomen. Exploratory laparotomy was performed and revealed a large cystic hypervascularized mass depending on the transverse colon and mesocolon. A wide excision of the lesion was performed with segmental colectomy. No postoperative complications were noted. The microscopic examination revealed a vaguely nodular growth of undifferentiated small round cells, arranged in solid sheets separated by thin fibrous septa with a scarce stroma. After an uncomplicated post-operative course, the patient
Anomalies of the peritoneum and the colon are quite common. Some of these anomalies can disturb the normal digestive and absorptive functions of the intestine and the others might result in formation of volvulus or impede the blood supply of the intestine. We report a rare, combined variation of peritoneum and ascending colon. In a 70-year-old male cadaver, the greater omentum was very small and extended only for about an inch below the transverse colon. From its lower end, a fibrous band extended to the right wall of the upper part of ascending colon. There was a deep constriction on the right wall of the ascending colon at the site of attachment of the fibrous band. The ascending colon was grossly dilated. Further, the ascending colon was mobile and presented a small ascending mesocolon along its left edge. We discuss the possible embryological basis and clinical and surgical relevance of the case..

The presence of gas within the inferior mesenteric vein is usually found in patients with diverticular disease of the colon and indicates either a direct fistula with intestinal gas entering the vein through the fistula, the presence of gas producing organisms within the vein, or both of these conditions simultaneously. Jensen (1) described two patients with pneumopylephlebitis and described inflammatory findings associated with the inferior mesenteric vein in two patients who were felt to have intramesocolic diverticular perforation. They suggested that a water-soluble contrast study could help identify and localize the site of communication between colon and portal venous system. They also emphasized that physical findings of active diverticulitis do not need to be present in these patients. Our first patient emphasizes this point further by showing that even intra-operative findings of septic phlebitis may be subtle unless a careful examination of the colon or the tissues surrounding the ...
RADIOLOGY: AORTA: Case# 39: AORTO-ENTERIC FISTULA; S/P GRAFT. This is a 79 year old male who is S/P repair of ruptured aortic aneurysmwith aortoiliac grafts. He presents now with upper GI hemorrhage. There is a large amount of high attenuation material within the bowel lumen, particularly in the duodenum and mid small bowel. There is also high and low attenuation density surrounding the aortic graft extending into the left anterior pararenal space. Gas is noted around the aorta and within these retroperitoneal collections. No active sites of contrast extravasation are demonstrated. Aortoenteric fistula accounts for 10% of small bowel bleeding. It isusually related to prosthetic aortic grafts, with 80% of fistulas forming with the duodenum where it crosses over the aorta. It may be seen as soon as three weeks following graft surgery.Typical findings include gas in the retroperitoneal soft tissues near the fistula site and loss of the normal fat plane between the duodenum and the aorta. - 00132791.jpg
PARTNER Trial is First Randomized Comparison in Seriously Ill Seniors New Orleans, LA - Death rates are similar at one year for a catheter-based method of replacing heart valves and conventional surgery in older high-risk patients, though endpoints such as stroke and major bleeding show marked differences, according to research from the PARTNER Trial presented today at the American College of Cardiologys 60th Annual Scientific Session. ACC.11 is the premier cardiovascular medical meeting, bringing together cardiologists and cardiovascular specialists to further advances in cardiovascular medicine.. Aortic stenosis - a clogged valve to the arterial expressway that transports oxygen-rich blood from the heart - affects up to 9 percent of the U.S. population older than 65, and incidence increases with age. Over time, aortic stenosis can create serious cardiac problems as the heart strains to pump blood through a narrowing three-flap exit. Standard treatment for severe stenosis is open-heart surgery ...
Multiple myeloma is on the list of neoplasia that may be associated with human immunodeficiency virus infection. It is an affection that aggravates the prognosis in these particular patients. We present the case of a patient with multiple myeloma and HIV infection, revealed by renal failure. This was a 59-year-old patient who was received to the Department of nephrology for renal failure associated with severe aregenerative pancytopenia. In etiological investigations, multiple myeloma associated with HIV1 infection was found. The evolution was unfavorable, marked by the death of the patient caused by digestive haemorrhage before the start of antiretroviral treatment and chemotherapy.
Methods and apparatus for determining the occurrence of an apnea, patency and/or partial obstruction of the airway are disclosed. Respiratory air flow from a patient is measured to give an air flow signal. The determination of an apnea is performed by calculating the variance of the air flow signal over a moving time window and comparing the variance with a threshold value. One determination of partial obstruction of the airway is performed by detecting the inspiratory part of the air flow signal, scaling it to unity duration and area and calculating an index value of the amplitude of the scaled signal over a mid-portion. Alternatively, the index value is a measure of the flatness of the air flow signal over the mid-portion. One determination of patency of the airway is performed by applying an oscillatory pressure waveform of known frequency to a patients airway, calculating the magnitude of the component of said air flow signal at the known frequency induced by the oscillatory pressure waveform and
Rectal Cancer 1. What is Rectal Cancer?. Rectal Cancer is cancer is a tumor arising from the lowest 15 centimeters of the large intestines, lying within the pelvis and connecting the colon to anus. Rectal cancer, unlike colon cancer, has a tendency to recur locally within the pelvis in the other organs near the colon and has a worse outcome. Local recurrence of rectal cancer is common (15-45%) after standard surgery and is often catastrophic. It is difficult to cure, and the associated symptoms are debilitating. Accordingly, preventing local recurrence is one of the main treatment goals with rectal cancer. Roughly one third of all colorectal cases involve the rectum.. 2. How does one know if one has rectal cancer?. Rectal cancer can cause many symptoms that require a person to seek medical care. However, rectal cancer may also be present without any symptoms, hence it is important to have routine health screening check up. Symptoms, to be aware of include the following:. * Bleeding. - Seeing ...
2. Low-Risk Group Can Avoid Surgery for Locally Advanced Rectal Cancer: A retrospective analysis of 145 stage I-III rectal cancer patients shows that those patients who have a complete response after chemoradiotherapy and chemotherapy had a similar 4-year survival rate regardless of whether they had surgery or opted for surveillance. In general, about 40% of patients with stage I-III disease have disappearance of their tumors after systemic therapy. The 4-year overall survival rate was 91% and 95% in the no surgery and standard surgery groups, respectively. There was no difference in the rate of distant recurrences between the two groups. These data continue to suggest that non-operative management does not compromise oncologic outcome, and that preservation of the rectum is achieved in a majority of patients, concluded the authors. ...

Resistant glucan (RG) and hydrogenated resistant glucan (HRG) are new dietary fiber materials developed to decrease the risk of metabolic syndrome and lifestyle-related diseases. We investigated the metabolism and bioavailability of RG and HRG using rats and humans. Purified RG and HRG were used as test substances. After 25 Wistar male rats (270 g) were fed with an experimental diet (AIN93M diet with the cellulose replaced by β-corn starch) ad libitum for 1 week, they were used for the experiment involving blood collection and circulating air collection. Ten participants (5 males, 22.5 y, BMI 20.4 kg/m2; 5 females, 25.8 y, BMI 20.9 kg/m2) voluntarily participated in this study. The study was carried out using a within-subject, repeated measures design. Effects of RG and HRG on the response for blood glucose and insulin and hydrogen excretion were compared with those of glucose and a typical nondigestible and fermentable fructooligosaccharide (FOS) in rats and humans. Available energy was evaluated

The disorder often remains quiet and easily controlled for long periods of time. Most people with Crohns disease continue to pursue their goals in life, go to school, marry, have a family and work with few limitations or inconveniences; however, some problems can occur. Arthritis, eye and skin problems, and-in rare instances- chronic liver conditions may develop. The disease can occur around the anal canal. Open sores called fissures can develop, which are often painful. A fistula, a tiny artificial channel that burrows from the rectum to the skin around the anus, can also form. In addition, when inflammation persists in the ileum or colon, narrowing and partial obstruction may occur. Often surgery is required to treat these problems. Cancer is not a worrisome outcome of Crohns disease, as it occurs only slightly more frequently among sufferers of the disease than in the general population.. ...

Snoring is caused by a partial obstruction of your airway. As you fall asleep, muscles in your soft palate, throat and tongue relax. If those muscles relax too much, they can fall into the back of your throat and partially obstruct your airway. As you breathe, the air passes through the blocked airway and causes snori
There is lack of evidence to prove a few of the above conditions. Therefore, more evidence is required in order to rate the effectiveness of Pygeum for usage regarding these conditions.. The Animal Trial Data. When a study was conducted to see the effects of PAE in animals, the results were all positive. In animals, the positive results were for hypophyseal- genitor- adrenal axis & prostatic adenoma. In the pretreatments of the rabbit as subjects with Pygeum, it seemed to reduce the partial obstruction outlet in the dysfunction of bladders which were secondary to the BPH.. It was further reported that it also helps in the reduction of gland size. For rat prostatic fiber blast proliferation, PAE seemed to be a potent inhibitor. The PAE even showed some anti-inflammatory activities which can affect the size of the gland.. The Clinical Data for Pygeum. There are a lot of trials that can be found for Pygeum which are mainly in Europe. These trials can be seen to encourage but still requires a lot ...
