Feeding difficulties and foregut dysmotility in Noonan's syndrome. (1/389)

PURPOSE: Noonan's syndrome is a common dysmorphic syndrome in which failure to thrive and gastrointestinal symptoms are frequent but poorly understood. DESIGN: Twenty five children with Noonan's syndrome were investigated by contrast radiology, pH monitoring, surface electrogastrography (EGG), and antroduodenal manometry (ADM). RESULTS: Sixteen had poor feeding and symptoms of gastrointestinal dysfunction. All 16 required tube feeding. Seven of 25 had symptoms of foregut dysmotility and gastro-oesophageal reflux. In the most symptomatic children (four of seven) EGG showed fasting frequency gradient loss along the stomach fundus and pylorus with antral postprandial frequency loss. ADM showed shortened fasting cycle length, with abnormal phase III and shortened postprandial activity containing phasic contractions. IMPLICATIONS: Gastroduodenal motor activity was reminiscent of 32-35 week preterm patterns. The feeding difficulties appear to resolve as gut motility matures. In Noonan's syndrome, feeding problems appear to be the result of delayed gastrointestinal motor development.  (+info)

Colorectal cancer: risk factors and recommendations for early detection. (2/389)

Spurred by mounting evidence that the detection and treatment of early-stage colorectal cancers and adenomatous polyps can reduce mortality, Medicare and some other payors recently authorized reimbursement for colorectal cancer screening in persons at average risk for this malignancy. A collaborative group of experts convened by the U.S. Agency for Health Care Policy and Research has recommended screening for average-risk persons over the age of 50 years using one of the following techniques: fecal occult blood testing each year, flexible sigmoidoscopy every five years, fecal occult blood testing every year combined with flexible sigmoidoscopy every five years, double-contrast barium enema every five to 10 years or colonoscopy every 10 years. Screening of persons with risk factors should begin at an earlier age, depending on the family history of colorectal cancer or polyps. These recommendations augment the colorectal cancer screening guidelines of the American Academy of Family physicians. Recent advances in genetic research have made it possible to identify persons at high risk for colorectal cancer because of an inherited predisposition to develop this malignancy. These patients require aggressive screening, usually by lower endoscopy performed at an early age. In some patients, genetic testing can guide screening and may be cost-effective.  (+info)

Physician intention to recommend complete diagnostic evaluation in colorectal cancer screening. (3/389)

Primary care physicians (PCPs) often do not recommend complete diagnostic evaluation (CDE; i.e., diagnostic colonoscopy or the combination of flexible sigmoidoscopy and barium enema X-ray procedures) for patients with an abnormal screening fecal occult blood test (FOBT+) result. Information is needed to understand why PCPs do not recommend CDE. In the spring of 1994, a telephone survey was carried out using a random sample of 520 PCPs in Pennsylvania or New Jersey who had patients that were targeted for an FOBT screening program. Survey data were obtained from 363 (70%) PCPs on physician practice characteristics; personal background; perceptions concerning FOBT screening, CDE performance, and patient behavior; social influence related to CDE; and intention to recommend CDE for FOBT+ patients. Physician CDE intention scores were distributed as follows: low (22%), moderate (51%), and high (27%). Multivariate analyses demonstrate that physician board certification status, time in practice, belief in CDE efficacy, and belief that CDE is standard practice were positively associated with CDE intention, whereas concern about CDE-related costs was negatively associated with CDE intention. Among physicians in larger practices, perceived FOBT screening efficacy was negatively associated with CDE intention, and belief in the benefit of CDE was positively associated with outcome. There is substantial variability in CDE intention among PCPs. Physician perceptions about FOBT screening and follow-up are associated with CDE intention, are likely to influence CDE performance, and may be amenable to educational intervention. Additional research is needed to evaluate the impact of educational interventions on CDE intention and performance.  (+info)

Cervical osteoarthropathy: an unusual cause of dysphagia. (4/389)

PRESENTATION: A 72-year-old man complained of progressive dysphagia for solids associated with a sensation of foreign body in his throat for 2 years. A barium swallow showed a bridging osteophyte between C4 and C5 vertebrae indenting the oesophagus posteriorly and displacing it anteriorly. OUTCOME: He refused surgical intervention and was given dietary advice. After 6 months, his weight was steady and he was able to swallow semi-solid food without difficulty.  (+info)

The risks of screening: data from the Nottingham randomised controlled trial of faecal occult blood screening for colorectal cancer. (5/389)

AIMS: To determine the harm that ensues from faecal occult blood (FOB) screening for colorectal cancer. METHODS: 150 251 people were randomly allocated either to receive biennial Haemoccult FOB tests (n =75 253) or not to be contacted (n=74 998). Study group patients returning positive tests were offered colonic investigation; 1774 underwent complete investigation of the colon. RESULTS: There was no significant difference in the stage at presentation of interval versus control group cancers. Survival in the interval cancer group was significantly prolonged compared with the control group. Sensitivity for colonoscopy or flexible sigmoidoscopy and double contrast barium enema (DCBE) was 96.7%. There were no complications of DCBE but seven (0.5%) complications of colonoscopy, of which six required surgical intervention. There were no colonoscopy related deaths. No patients without colorectal cancer died within 30 days of colonic investigation. Five patients died within 30 days of surgery for screen detected colorectal neoplasia and a further two died without having surgery. Six patients died after 30 days but within two years of surgery for screen detected benign adenomas or stage A cancers; in all cases the cause of death was not related to colorectal cancer. CONCLUSIONS: There was investigation related morbidity but no mortality and little to support overdiagnosis bias. The group returning falsely negative tests had a better outcome compared with the whole control group. There is a negative side to any screening programme but mortality reduction in this and other trials suggests that a national programme of colorectal cancer screening should be given consideration.  (+info)

Audit of the investigation of iron deficiency anaemia in a district general hospital, with sample guidelines for future practice. (7/389)

Iron deficiency anaemia commonly presents in patients who are asymptomatic. In the absence of published guidelines the search for a cause in such cases is frequently uncoordinated, and risks delay in the diagnosis of pathologies requiring urgent attention. This audit was undertaken to determine how thoroughly patients referred to the gastrointestinal unit in a district general hospital between 1990 and 1995 had been investigated, and to draw up guidelines for future practice on the basis of its results. From the case notes of 334 patients examined endoscopically for anaemia 126 were identified as having both proved iron deficiency and a lack of clinical pointers to its cause. The percentage and details of diagnoses made during initial study and a median follow up period of 28 months were ascertained, together with the certified diagnoses of patients who had died. A cause of iron deficiency was identified in 48 (38%) of patients, 22 with cancer. Ten others received a diagnosis during follow up, of whom three died from the condition to which their anaemia had been attributed. Death certificates supplied diagnoses of potential relevance in three further cases. The main gaps in endoscopic coverage consisted of omitting duodenal biopsy or colonoscopy after negative upper gastrointestinal endoscopy. Moreover, diagnosis of certain extraintestinal pathologies, including cancers, was sometimes delayed for lack of liaison between gastroenterologists and other specialists. These and other points have been addressed in the guidelines now proposed.  (+info)

Abdominal aortic aneurysm: the role of clinical examination and opportunistic detection. (8/389)

OBJECTIVES: to investigate the method of discovery of abdominal aortic aneurysms (AAA) in a district general hospital setting. DESIGN: retrospective study. MATERIALS AND METHODS: we analysed 198 patients with an AAA who presented to our unit over a 3-year period. The method of initial diagnosis, size of the AAA and whether this was palpable, irrespective of the method of detection, were recorded. RESULTS: ninety-five (48%) were discovered clinically, 74 (37.4%) during a radiological investigation, and 29 (14.6%) at laparotomy. Of the 74 AAAs first detected radiologically, subsequent physical examination showed that 28 (37.8%) were in fact palpable and missed at presentation. The average size of those discovered clinically (6. 48+/-1.32 cm) was larger than those found radiologically (5.37+/-1. 44 cm, p<0.001) or at operation (5.43+/-1.48 cm, p=0.039). The average diameter of the palpable AAAs was also greater than that of the non-palpable AAAs (6.42+/-1.24 cm vs. 4.86+/-1.38 cm, p<0.001). CONCLUSIONS: opportunistic detection of a clinically unsuspected aneurysm during clinical examination or investigation for another reason is the most common way the diagnosis of an AAA is made. Almost half of the aneurysms were diagnosed clinically, but physical examination also missed more than a third of those detected radiologically. Despite technological advancement, clinical examination still plays a paramount role in the detection of AAAs. Larger AAAs are usually palpable and more likely to be detected on clinical examination.  (+info)

Barium sulfate, used as a radio-opaque marker in some orthopedic bone cements, has been shown to escape into the surrounding tissues. This may present a potential hazard. In particular, phagocytic cells may be exposed to relatively high internal levels of barium once the particles have been phagocytosed. Mouse peritoneal macrophages exposed to barium sulfate for periods up to 144 hr showed a marked cytoplasmic vacuolization from which they recovered only partially. Barium sulfate did not appear to damage the cell membrane as judged by lactice dehydrogenase release. In the relatively low doses and with the periods of exposure described here, barium sulfate does not appear to present a serious toxic hazard in the short term. It is possible, however, that longer exposures and larger doses may result in the death of phagocytic cells which have ingested barium sulfate. ...

Barium sulfate in suspension is frequently used medically as a radiocontrast agent for X-ray imaging and other diagnostic procedures. It is most often used in imaging of the GI tract during what is colloquially known as a barium meal. It is administered orally, or by enema, as a suspension of fine particles in a thick milk like solution (often with sweetening and flavoring agents added). Although barium is a heavy metal, and its water-soluble compounds are often highly toxic, the low solubility of barium sulfate protects the patient from absorbing harmful amounts of the metal. Barium sulfate is also readily removed from the body, unlike Thorotrast, which it replaced. Due to the relatively high atomic number (Z = 56) of barium, its compounds absorb X-rays more strongly than compounds derived from lighter nuclei.. ...

The majority of the barium present in the pulping process exits the digester as barium carbonate. Barium carbonate dissolves in the bleach plant when the pH drops below 7 and, if barium and sulfate concentrations are too high, begins to precipitate as barium sulfate. Barium is difficult to control because a mill cannot avoid this carbonate-to-sulfate transition using common bleaching technology. An advantage in controlling barium scales is that the sulfate, once formed, will not redissolve to any appreciable extent, and this reduces the rate at which barite scale can form in other locations in the bleach plant. A mill has relatively few options for controlling barium sulfate scale. The first is to ensure very good debarking to minimize barium entering the mill with the wood. The second option is to minimize sulfate content of the first chlorine dioxide stage in the bleach plant. Sulfate is minimized through good brown stock washing and by using sulfuric acid for pH control instead of chlorine ...

Certain compounds of barium, such as barium sulfate, are not toxic and can be put in the body. We can see where the barium travels in the body by X-rays and this can tell us whether there are problems, such as blockages. The barium sulfate builds up inside the body accumulating in organ systems. Barium sulfate absorbs the X-Rays as they pass through the body and an image is formed from the points where the rays have not passed through. It is useful because it provides a reasonably detailed image from very limited radiation exposure, compared with a CT scan for instance. Barium sulfate can be used as a pigment, too. Other barium compounds have several other uses. ...

Barium salts other than barium sulfate cause shifting of potassium into the intracellular space and are thought to block potassium efflux. Typical clinical findings after ingestion include severe vomiting and diarrhea due to increased GI motility. Ventricular dysrhythmias occur with QT prolongation due to the profound hypokalemia that occurs. Muscle weakness is common as well. Treatment includes possible oral administration of magnesium sulfate to try and convert some of the barium to barium sulfate, the insoluble form. Supportive care and ventilator support are needed. Potassium administration is usually needed when there are cardiovascular manifestations such as ventricular dysrhythmias; however, the potassium levels must be closely monitored as once the barium toxicity resolves, the potassium can shift back out of the intracellular compartment and hyperkalemia may occur with continued exogenous administration. Hemodialysis has been reported to enhance elimination of the barium. ...

Zinc sulfate is the inorganic compound with the formula ZnSO4 as well as any of three hydrates. It was historically known as white vitriol. It is a colorless solid that is a common source of soluble zinc ions. Production and reactivity. Zinc sulfate is produced by treating zinc with aqueous sulfuric acid:. Zn + H2SO4 + 7 H2O → ZnSO4(H2O)7 + H2. Pharmaceutical grade zinc sulfate is produced from high purity zinc oxide:. ZnO + H2SO4 + 6 H2O → ZnSO4(H2O)7. In the laboratory, it can also be prepared by adding solid zinc to a copper(II) sulfate solution:. Zn + CuSO4 → ZnSO4 + Cu. In aqueous solution, all forms of zinc sulfate behave identically. These aqueous solutions consist of the metal aquo complex [Zn(H2O)6]2+ and SO42- ions. Barium sulfate forms when these solutions are treated with solutions of barium ions:. ZnSO4 + BaCl2 → BaSO4 + ZnCl2. With a reduction potentia of -0.76, zinc(II) reduces only with difficulty.. ...

For many types of cancer, progress in cancer screening has offered promise for earlier detection and higher cure rates. The term screening refers to the regular use of certain examinations or tests in persons who do not have symptoms of cancer.. Screening is crucial for the prevention and early detection of colorectal cancer. The American Cancer Society currently recommends that people at average risk of colorectal cancer begin being screened for colorectal cancer at the age of 50. Screening may need to begin at a much earlier age for people with a personal or family history of adenomatous polyps, FAP, HNPCC, colorectal cancer, or chronic inflammatory bowel disease.. Several screening strategies are currently available. These include the fecal occult blood test (FOBT), flexible sigmoidoscopy, colonoscopy and double contrast barium enema. The frequency of screening depends on the method. In general, FOBT is performed every year, sigmoidoscopy is performed every five years, and colonoscopy is ...

0010] Traditional methods for producing battery plates for lead-acid batteries generally involve a mixing, curing and drying operation in which the active materials in the battery paste undergo chemical and physical changes that are used to establish the chemical and physical structure and subsequent mechanical strength necessary to form the battery plate. To produce typical battery plates, materials are added to commercial paste mixing machines common in the industry in the order of lead oxide, flock, water and sulfuric acid, which are then mixed to a paste consistency. The flock component is a fibrous material, usually composed of polyester, nylon or acrylic fibers, which is added optionally to the paste to increase the mechanical strength of the pasted plate. An expander component is conventionally added to the negative paste consisting of a mixture of barium sulfate, carbon black and lignosulfonate that is added to the negative paste to improve the performance and cycle lifetime of the ...

False-colour barium enema X-ray of the human abdomen showing a cancer of the ascending colon; the tumour appears as the oval shadow over the right pelvic bone (left on image). Opaque to X- rays, barium is given orally (barium meal) for investigations of the oesophagus, stomach & duodenum and rectally (as a barium enema) to examine the rectum & colon. The colon (large intestine) consists of four sections - the ascending, transverse, descending and sigmoid colons. Here, the ascending colon rises at left, its transverse (horizontal) section appears in centre, and the descending part at right, which connects with the rectum via the sigmoid colon. - Stock Image M134/0099
Previously, sodium hydroxide has been prepared using two processes namely, an Electrolytic process and Caustisization of soda ash. Both methods require a lot of energy and products made under these conditions are very expensive. The present study was aimed at investigating whether barium hydroxide rather than slaked lime can be used in the lime-soda process. The barium hydroxide was obtained from carefully selected barium compounds which thermally decomposed within temperature ranges of 600°C-700°C to barium oxide. The barium compounds used were barium sulphite and barium nitrate. The barium hydroxide was reacted with sodium carbonate and formed sodium hydroxide and barium carbonate as slaked lime in the lime-soda process that produces sodium hydroxide and calcium carbonate. The results have confirmed beyond any reasonable doubt that both barium sulphite and barium nitrate readily decompose thermally in the temperature ranges 650°C-700°C. Barium sulphite decomposes to barium oxide and ...
Colorectal cancer causes significant morbidity and mortality in the United States. The incidence of colorectal cancer can be reduced with increasing efforts directed at mass screening of average-risk adults 50 years and older. Currently, fecal occult blood test and flexible sigmoidoscopy have the highest levels of evidence to support their use for colorectal cancer screening. Colonoscopy does not have a proven colorectal cancer mortality benefit, but it does have the greatest single-test accuracy, and it is the final test in the pathway to evaluate and treat patients with other abnormal screening tests. Double-contrast barium enema has sparse data of effectiveness. Computed tomographic colonography, fecal DNA testing, and Pillcam Colon are promising tests that need further study before they can be recommended for widespread screening. Routine screening should continue until 75 years of age. There is good evidence that fiber and antioxidants are not effective for primary prevention of colorectal cancer;
Membrane distillation (MD) is fast evolving as a desalination technology for high-salinity waters where scaling remains a major challenge. This paper reports the scaling reduction in carbon nanotube-immobilized membranes (CNIMs) and by the use of the antiscalant polyacrylic acid. High concentrations of CaSO4, CaCO3, and BaSO4 were deliberately used to initiate scaling on the membranes. It was observed that after ten hours of operation in a highly scaling CaSO4 environment, the CNIM showed 127% higher flux than what was observed on a membrane without the CNTs. The trends were similar with CaCO3 and BaSO4, where the CNIM showed significantly improved antiscaling behavior. The normalized flux declination for CNIM was found to be 45%, 30%, and 53% lower compared to the pristine membrane with CaSO4, CaCO3, and BaSO4 solutions, respectively. The use of antiscalant in the feed solution was also found to be effective in improving antiscaling behavior, which reduced salt deposition up to 28%, and the water vapor
Up to 10 million barium enema x-ray procedures are performed each year in the United States to diagnose disorders of the lower digestive tract. The exact cause of the adverse reactions is unclear. The manufacturer, E-Z-Em, Inc., of Westbury, N.Y., asked physicians to stop using enema tips with inflatable latex cuffs. The firm also stated in recall letters to health professionals and purchasers that water-soluble proteins in products with latex may trigger severe allergic reactions, especially in patients who have a history of allergies. The recalled E-Z-Em tips have inflatable cuffs (used to prevent barium leakage from the rectum during the procedure) that contain latex. Through the October 1990 FDA Drug Bulletin, the agency also alerted U.S. physicians to the problem, requesting reports of allergic reactions to barium enemas or to products containing latex. ...

Barium ferrate is the chemical compound of formula BaFeO4. This is a rare compound containing iron in the +6 oxidation state. The ferrate (VI) ion has two unpaired electrons, making it paramagnetic. It is isostructural with BaSO4, and contains the tetrahedral [FeO4]2− anion. The ferrate(VI) anion is paramagnetic due to its two unpaired electrons and it has a tetrahedral molecular geometry. X-ray diffraction has been used to determine the orthorhombic unit cell structure (lattice vectors a ≠ b ≠ c, interaxial angles α=β=γ=90°) of nanocrystalline BaFeO4. It has a pnma space group (point group: D2h) with lattice parameters a=0.8880 nm, b=0.5512 nm and c=0.7214 nm. The accuracy of the X-Ray diffraction data has been verified by the lattice fringe intervals from High-Resolution Transmission Electron Microscopy (HRTEM) and cell parameters calculated from Selected Area Diffraction (SAED). Infra-red peaks of barium ferrate are observed at 870, 812, 780 cm−1. BaFeO4 has a magnetic moment of ...

Two mud volcanoes in the Gulf of Mexico were examined to understand barium cycling in shallow seafloor sediment at regions of intense methane expulsion. Due to anaerobic oxidation of methane and sulfate reduction, barium interacts with methane and sulfate, producing barite fronts at the sulfate-methane transition and barium-rich pore fluids underneath. Formation waters likely feed volcanoes and deliver large amounts of Ba2+ to the system from below. Locally elevated Ba2+ concentrations amplified cycling, producing sigmodial pore water profiles in the shallowest sediment. The expulsion of Ba-rich fluids directly to the water column concentrates barite in surficial sediments, which can also enhance cycling. Further, two types of barium-rich, carbonate nodules were recovered. Rocky nodules resemble buried carbonate crusts, diagenetically altered by pore fluids. Smooth nodules are likely preserved barite fronts marking past sulfate-methane transitions. Both types of nodules can serve as a modern ...
A hiatus hernia may be diagnosed after an endoscopy or an X-ray - Dr. B C Shah will make an appointment for you to have this done in hospital.. An endoscopy is the most common test for a hiatus hernia. An endoscope (a long, tube-like viewing instrument that contains a video camera and light source) is passed down the oesophagus (gullet) into the stomach.. If youre having an X-ray, you may swallow a watery paste made from barium sulphate. Its a heavy, odourless powder thats insoluble (doesnt dissolve) and isnt poisonous. It coats the inside of the stomach and makes it easier to see the digestive system when an X-ray is performed.. Both procedures allow the doctor to check for evidence of a hiatus hernia.. ...

What to expect: During an upper GI series, patients drink barium while the radiologist watches on a monitor as it passes through the patients digestive tract and obtains periodic x-ray images. An upper GI series or a barium enema is usually completed within 30 to 60 minutes. A small bowel series, which may be performed on its own or with an upper GI series, involves serial x-rays of the abdomen after drinking barium. A small bowel series may take two or more hours to allow the contrast to pass through the entire small intestine. After these examinations, you can resume a regular diet and take medications by mouth (unless told otherwise by your doctor), and you should be able to resume normal activities. You will be encouraged to drink additional water for 24 hours after the examination, For a barium enema, the radiologist administers barium into the colon through a small tube inserted into the rectum and monitors its progress on a monitor, taking periodic x-ray images. Patients may feel ...
The substitution of sulfate in apatite is of potential importance in synthetic biomaterials used in bone repair and reconstruction. The counter ion (e.g., Na+, K+, Mg2+, Sr2+) in the sulfate reagent may also be used as a source of medically beneficial ions. An understanding of the structural parameters controlling sulfate substitution is also important in expanding our knowledge beyond the substitution of carbonate in apatites.. The incorporation of sulfate in calcium and strontium hydroxylapatites, prepared in aqueous solution at pH 9, was verified by combustion analysis of sulfate, infrared and Raman spectroscopy, and by determination of unit-cell parameters. Sulfate could not be incorporated into barium hydroxylapatite because of the preferential formation of BaSO4.. The amount of sulfate substituted in the apatite was affected by the mole ratio of sulfate to phosphate in the reaction mixture and by the nature of the counter ion in the sulfate reagent. When sodium is the counter ion in the ...
