Sample records for abdominal cavity

  1. Radiography of the abdominal cavity

    Radiography is a very important part of the diagnostic procedure in many small animal diseases. Technically perfect X-rays are essential for the exact diagnosis. The general appearance of the abdominal cavity should be evaluated at first, e.g. the overall contrast and the definition of the visualized organs. Then particular attention should be paid, if there is any peritoneal effusion or free air in the peritoneal cavity. Subsequently each radiographically visible organ has to be evaluated for its position, size, shape and radiographic density

    Full Text Available 85 patients with abscesses of abdominal cavity (AAC at the age from 5 to 15 years old were observed. 37 (43.5% patients had unformed and 48 (56.5% patients had formed intra-abdominal abscesses. Devised methods of complex investigation were used to diagnose postoperative abscesses of the abdominal cavity; they included the index of blood toxicity (IBT and the index of spontaneous agglomeration leukocytes (ISAL in combination with dynamic purposeful using of searching ultrasound sonography and clinical signs. The complex diagnostics including ultrasound sonography, indexes of blood toxicity, spontaneous agglomeration of leucocytes and clinical signs can allow us significantly improve the effectiveness of diagnosis of intra-abdominal abscesses in the early stages after surgical operation regarding to appendicular peritonitis (AP in children and to choose the optimal method of surgical treatment.

  3. Abdominal cavity exploration with kinetic scintimaging

    Nuclear medicine procedures are being utilized in an increasing variety and number of intra-abdominal clinical problems. These non-invasive intra-abdominal exploratory scintimaging procedures are often dynamic or kinetic in nature, i.e. revealing primarily functional information even to the point of employing adjunctive drugs and multiple simultaneous radiotracers. The advent of correlative non-invasive diagnostic imaging modalities has thus far largely complemented abdominal nuclear medicine procedures. The luminal gastro-intestinal tract has yielded to investigation with radiotracers with procedures now widely employed to study gastric function, gastro-oesophagal reflux and intestinal bleeding. The role of hepatic and splenic reticuloendethelial compartment imaging has been strengthened by increased dependability, and remains as the first line screening test for a variety of suspected intrahepatic lesions, especially neoplasia. The recent introduction of improved hepatobiliary radiotracers, mostly iminodiacetic acid derivatives, has considerably expanded the scope of diagnostic investigations of the liver, especially in problems of jaundice and acute cholecystitis. Pancreatic imaging continues to be a disappointment and at best is only adjunctive to correlative imaging procedures. Some hope may be seen in the recent reports of successful pancreatic imaging with positron emission tomography utilizing labelled amino-acid derivatives. Diffuse abdominal processes, especially abcesses and suspected infection, have been efficaciously approached with 67Ga citrate and also, more recently, 111-In-labelled leucocytes. Many of these advances and applications have also been readily applicable to pediatric problems. (author)

Blinov in the middle of the XX century in his monograph “Adhesive disease”, wrote that post-surgical adhesions in the abdominal cavity – is a defect of surgeon. At present time, it is known that adhesive disease is the adhesions of connective tissue between adjacent organs or the peritoneal surface resulting from damage of their walls (more often during a surgical intervention). As of today, there ar...

  7. The MRI of extraadrenal pheochromocytoma in the abdominal cavity

    The purpose of this study was to summarize the MR appearances of extraadrenal pheochromocytoma in the abdominal cavity and evaluate the capabilities of MRI in diagnosis of the tumor. Eleven consecutive patients with an extraadrenal pheochromocytoma in abdominal cavity who underwent preoperative 0.5 T (n = 5) or 1.5 T (n = 6) superconductor MRI and had a surgical resection were enrolled in the study. The MR scanning protocol included axial T2-weighted imaging with or without fat-suppressed sequences, axial and coronal uncontrast and contrast T1-weighted sequences with or without fat suppression. The extraadrenal pheochromocytomas were found in retroperitoneum (n = 5), the urinary bladder (n = 1), the pelvis (n = 1), the right prerenal area (n = 1), the renal hilus (n = 1), the left paramusculus psoas major (n = 1) and liver (n = 1). The mean maximal diameter of tumors was 55.9 mm (range 17.8-162.2 mm). The high signal intensity was seen on T2-weighted imaging in all tumors compared to muscle or liver, especially with fat suppression. The intratumoral septa and capsules were shown in 63.6% and 72.7% of cases, respectively, which had low signal intensity on T2-weighted imaging. These relative characteristics may be helpful for qualitative diagnosis of extraadrenal pheochromocytomas with MRI. Other usefulness of MRI was to locate the position, to decide the range of tumors and to show well the relationship between the tumor and near structures

    Full Text Available Ectopic hepatocellular carcinoma (HCC is a very rare clinical entity that is defined as HCC arising from extrahepatic liver tissue. This report presents a case of ectopic multiple HCC arising in the abdominal cavity. A 42-year-old otherwise healthy male presented with liver dysfunction at a general health checkup. Both HCV antibody and hepatitis B surface antigen were negative. Laboratory examination showed elevations in serum alpha-fetoprotein and PIVKA-II. Ultrasonography and computed tomography revealed multiple nodular lesions in the abdominal cavity with ascites without a possible primary tumor. Exploratory laparoscopy was performed, which revealed bloody ascites and multiple brown nodular tumors measuring approximately 10 mm in size that were disseminated on the perineum and mesentery. A postoperative PET-CT scan was performed but it did not reveal any evidence of a tumor in the liver. The tumors resected from the peritoneum were diagnosed as HCC. The present case of HCC was thought to have possibly developed from ectopic liver on the peritoneum or mesentery.

  9. The CT findings of non-Hodgkin's lymphoma in the abdominal cavity of children

    Objective: To evaluate CT diagnostic value of non-Hodgkin's lymphoma in the abdominal cavity of children. Methods: CT manifestations of 14 cases of non-Hodgkin's lymphoma in the abdominal cavity of children were retrospectively analyzed. The patients included 8 boys and 6 girls, aging from 3-14 years. Ten cases were confirmed by operation and pathology, and 4 cases were confirmed by biopsy. Results: The main CT signs of non-Hodgkin's lymphoma in the abdominal cavity of children showed as follows: (1) 14 cases showed multiple huge irregular mass in abdominal cavity; (2) Bowel-wall thickened in 6 cases; (3) In 6 cases, enlarged mesenteric and retroperitoneal lymph nodes embodied the vessels of mesenteric and celiac trunk. This finding was so-called 'sandwich' sign; (4) Bowel demonstrated the sign of aneurysmal dilatation in 4 cases; (5) Two cases showed 'air-fluid level' sign in intestinal canal; (6) Three cases involved other adjacent abdominal organs, such as spleen in 1 case, kidney in 1 case, and liver in 1 case; (7) One case showed incomplete intestinal obstruction; (8) After contrast medium administration, the masses in 13 cases showed moderate enhancement; (9) Four cases showed ascites in abdominal cavity. Conclusion: CT is very useful for diagnosing and mapping the extension of non-Hodgkin' s lymphoma in the abdominal cavity of children

    Abdominal enterocele is a result of entering abdominal organs into peritoneal pockets and folds through the holes in mesenterium or into the adjoining cavities through defects in their walls. Enteroceles are localized at the sites where one segment of the gastrointestinal tract passes into another, in a pocket behind the cecum and sigmoid, between mesenteric layers of small intestine and colon, in the holes of mesenterium of vermiform appendage, gastrocolic and falciform ligaments, pockets and holes of broad ligament of the uterine, omental foramen, rectouterine excavation, and diaphragmal defects. We observed a 26 year old woman with enterocele entrapment in the abdominal cavity complicated by necrosis of part of the small intestine. PMID:26031155

    Guyon, Laurie; Claude Lesage, Jean; Betrouni, Nacim; Mordon, Serge

    2012-03-01

    A homogeneous illumination of intra-abdominal organs is essential for successful photodynamic therapy of the abdominal cavity. Considering the current lack of outstanding light-delivery systems, a new illumination procedure was assessed. A rat model of peritoneal carcinomatosis was used. Four hours after intraperitoneal injection of hexaminolevulinate, a square illuminating panel connected to a 635-nm laser source was inserted vertically into the abdominal cavity. The abdominal incision was sutured and a pneumoperitoneum created prior to illumination. Light dosimetry was based on the calculation of the peritoneal surface by MRI. The rats were treated with a light dose of 20, 10, 5 or 2.5 J/cm2 administered continuously with an irradiance of 7 mW/cm2. The homogeneity of the cavity illumination was assessed by quantification of the photobleaching of the tumor lesions according to their localization and by scoring of that of the liver and of the bowel immediately after treatment. Photobleaching quantification for tumor lesions relied on the calculation of the fluorescence intensity ratio (after/before treatment) after recording of the lesions during blue-light laparoscopy and determination of their fluorescence intensity with Sigmascan Pro software. The procedure led to a homogeneous treatment of the abdominal cavity. No statistical difference was observed for the photobleaching values according to the localization of the lesions on the peritoneum (p=0.59) and photobleaching of the liver and of the intestine was homogeneous. We conclude that this procedure can successfully treat the major sites involved in peritoneal carcinomatosis.

    Uterine perforation is a serious problem which can happen after intrauterine device (IUD) insertion. Migration of the IUD to the pelvic and abdominal cavity or adjacent organs may be seen following perforation of the uterus. Migration of an IUD to a far intra-abdominal site is extremely rare. The patient reported here had undergone an IUD placement 30 years previously and had no problems during this period. The IUD was incidentally found at the left upper quadrant of the abdomen in the mesent...

  19. Computer tomography in the diagnosis of disease of the abdominal cavity and retroperitoneal space

    It is ascertained that computer tomography of abdominal cavity organs is a promising diagnostics technique in cases when conventional radiography does not provide required information, especially for the diseases of liver parenchyma. The application of contrast substances enhances the detection of pathological changes. New contrast substances should be seeked for to enhance diagnostic capabilities of the computer tomography and to increase the difference between radiation absorption coefficient

  5. Is It Worthwhile to Fully Evaluate the Stomach in Every Ultrasound Examination of the Abdominal Cavity?

    To evaluate the usefulness of abdominal sonography in the fasting state with no hypotonic agents in the detection and exclusion of gastric lesions. One-hundred patients with normal upper gastrointestinal endoscopy, 94 patients with a major gastric abnormality (including 59 intraluminal tumors, three submucosal masses, 29 ulcers, two polyps and one hypertrophied gastric mucosa) and 75 patients with minor gastric abnormalities (mainly gastritis) were enrolled into the study. Of the 100 normal patients, ultrasound showed four false positive results with 96% specificity of the examination. Within the major gastric lesion group, ultrasound was true positive in 55 of 59 tumors, 15 of 29 ulcers, three of three submucosal masses and the case of giant gastric mucosa. It was negative in the detection of gastric polyps. It could detect only 8% of minor gastric abnormalities. Abdominal sonography in the fasting state, if carefully performed, is sufficiently accurate in detection and exclusion of major gastric lesions. Therefore, although it cannot replace endoscopic and barium studies of the stomach, careful evaluation of the stomach is recommended in every sonographic evaluation of the abdominal cavity

  9. Pathomorphologic aftereffects of chronic irradiation with γ-neutron source incorporated in the abdominal cavity (communication 2)

    The results were presented of radiometric and morphological studies of the viscera of dogs and sheep who lived 5 to 7 years with the Hertz-IR type γ-neutron standard radiation sources, implanted in the abdominal cavity. The most coarse dystrophic and sclerotic changes were found in the visceral sites adjacent to the radiation source or near it. It was suggested that spermatogenesis disorders resulting from chronic low-dose irradiation were due to not only the immediate action of ionizing radiation, but to total disorders of the trophicity of irradiated body as well

    Ozone is an oxidizing agent possessing potent in vitro microbicidal capacity. This study was designed to address the extent to which irrigation of the contaminated abdominal cavity using a saline solution primed with ozone is effective in reducing morbidity and mortality. Gelatin capsules containing different quantities of a premixed slurry of filtered human fecal material were implanted in the peritoneal cavities of a preliminary series of rats. Three inocula concentrations were selected for later experiments, based upon their ability to produce morbid consequences: (1) high (100% 1-day mortality), (2) medium (70% 3-day mortality, 100% abscess rate in survivors), and (3) low (100% 10-day survival, 100% abscess rate). Fecal and abscess bacteriology were similar in all rats. The peritoneal cavities of 240 rats then underwent fecal-capsule implantation (three groups of 80 rats/inoculum concentration). At celiotomy 4 hours later, equal numbers of rats from each group were randomly assigned to one of four protocols: (1) no irrigation, (2) normal saline irrigation, (3) saline-cephalothin irrigation, and (4) ozonated saline irrigation. Each treatment lasted 5 minutes, using 100 ml of irrigation fluid. Mortality was significantly reduced when, in lieu of no irrigation, any of the irrigation solutions were used. Additionally, ozonated saline statistically proved the most effective irrigating solution for reducing abscess formation in survivors.

    2015-10-01

    During 2011 - 2014 yrs in Surgical Clinic of The First City Clinic (Poltava) a relaparotomy was performed in 127 patients. There was established, that relaparotomy constitutes the only one procedure for such life threatening states, as intraabdominal bleeding, ileus in a decompensation stage, eventration, progressing peritonitis, abdominal compartment syndrome stages III - IV. The rate of relaparotomy application after performance of urgent operative interventions is bigger than after planned operations (ratio 4:1). Individual estimation of a state and choice of optimal surgical tactics during primary and secondary operative interventions are needed to improve the results of treatment. PMID:26946667

  13. Fate of gamma-interferon-activated killer blood monocytes adoptively transferred into the abdominal cavity of patients with peritoneal carcinomatosis

    Five patients with colorectal cancer widely metastatic to peritoneal surfaces have been treated i.p. with infusions of autologous blood monocytes made cytotoxic by in vitro incubation with human gamma-interferon. The monocytes were purified by a combination of cytapheresis and counter-current centrifugal elutriation procedures; each week approximately 350 million activated monocytes were given to patients as adoptive immunotherapy by a single i.p. instillation. On the eighth cycle of treatment the trafficking of i.p. infused blood monocytes was studied in two patients by prelabeling the cells with 111In. These activated cells became distributed widely within the peritoneal cavity. Two and 5 days after infusion their position within the peritoneum had not changed. When peritoneal specimens were obtained 36 h after 111In-labeled monocyte infusion, labeled monocytes were demonstrated to be associated with the serosal surfaces by autoradiographic analysis. Scintiscanning structures outside the abdominal cavity revealed that 111In-labeled monocytes infused i.p. did not traffic to other organs during the 5 days of the study. We conclude that i.p. adoptive transfer of autologous killer blood monocytes is an effective way of delivering these cytotoxic cells to sites of tumor burden on peritoneal surfaces in these cancer patients

  14. Content of the canceroembryonal antigen in tumours of the organs of the abdominal cavity and the retroperitoneal space

    The concentration of the canceroembryonal antigen (CEA) has been determined in vitro by the radioimmunological analysis of the blood plasma of 70 donors and 130 patients with malignant tumours of the intestine (6 persons), stomach (77), with relapsing gastric carcinoma (12), tumours of the pancreas (7), retroperitoneal space (18) and with inflammatory disease of the gastrointestinal tract (12). It is established that the radioimmunological test in vitro for CEA can be used not only for primary diagnosis of cancer of the rectum but also as a substantial supplement to the clinical diagnosis of carcinoma of the stomach and the pancreas. A relationship revealed between the rise in the content of CEA and the extent of malignancy provides additional information for correct diagnosing the stage of gastric carcinoma and a choice of an adequate method of treatment. Tolerance of the CEA level in the blood in retroperitoneal tumours and inflammatory diseases of the gastrointestinal tract may serve as a criterion for differential diagnosis of malignant newgrowths in the abdominal cavity

    Full Text Available Foram avaliados os resultados tardios da colocação de cálculos biliares humanos, de colesterol, na cavidade peritoneal de ratos. Constituíram-se cinco grupos: cinco ratos foram apenas laparotomizados com manuseio da cavidade; cinco foram laparotomizados e receberam um ponto com fio monofilamentar cinco zeros no sulco paracólico direito e mesentério; dez receberam cálculos que foram deixados livres na cavidade peritoneal; em dez, os clculos foram fixados no sulco paracólico direito e, finalmente, dez tiveram clculos fixados no mesentério. Os animais foram mortos após cinco meses de pós-operatório quando se observou a cavidade abdominal e foi coletado material para estudo histopatológico. Concluiu-se que os cálculos não foram absorvidos, desenvolveram uma reação peritoneal do tipo corpo estranho com formação de plastrão e foram envolvidos por tecido fibroso e células inflamatórias.It was evaluated the late results of human gallstones placed into peritoneal cavity of rats. Five groups were created. In the first (group A five rats were submitted only to laparotomy and handling of abdominal cavity, in the second (group B five rats were submitted to laparotomy and a stitch was placed into right abdominal wall and in mesenterium between the ileus and cecum, in the third (group C ten rats received a gallstone left free into abdomen, in the fourth (group D ten rats received a gallstone fixed into right abdominal wall and in the fifth (group E ten rats received a gallstone fixed in mesenterium between the ileus and cecum. One rat in each group was selected to be use as a pilot and were re-laparotomized after 1 month and 3 months, in order to look for any possible alteration. All rats were dead after five months when the abdominal cavity was observed and specimens were collected around the gallstones to histopathology. ln groups A and B there were not important macroscopic alterations. The gallstones were not absorved in groups C, D

  2. An Improved Approach to External Beam Radiation Therapy for Intra-Abdominal Cavity Lesions for Rural Cancer Centers

    Radiation therapy of abdominal lesions is problematic at best. The proximity of highly critical structures, tumor locations, and necessary margins combine to make prescription dose delivery with conventional 3-dimensional (3D) conformal techniques difficult. Others have tried to overcome these hurdles with newer modalities including intra-operative radiation therapy (IORT), intensity modulated radiation therapy (IMRT), and heavy particle irradiation. These techniques have had moderate success but are not readily available and are therefore limited in application. These factors have lead to the development of a modified, noncoplanar 4-field box technique that demonstrates significant improvement in critical structure sparing, i.e., kidney(s), bowel, and liver doses reduced while simultaneously improving isodose coverage to the target

The extensive wound is a gateway for infection. Moreover, increased secretion of serous fluid induces a hygienic problem and may lead to secondary skin infections or bedsores. The negative pressure wound therapy (NPWT) system is an innovative therapeutic method. It perfectly executes the TIME strategy, receiving more and more recognition. The study presented a case of a 62-year old male patient after several consecutive wound dehiscence episodes who was primarily treated for rectal cancer by means of low anterior resection of the rectum. Due to acute respiratory insufficiency after several operations, wound necrosis with dehiscence was observed. Considering the high risk of perioperative death we abandoned surgical treatment and introduced conservative management using negative pressure wound therapy until the patient's health improved. Literature regarding the above-mentioned issue was also reviewed. PMID:26816408

    Abdominal pain is one of the most common complaints by patients, and assessment of abdominal pain and associated symptoms can be challenging for home healthcare providers. Reasons for abdominal pain are related to inflammation, organ distention, and ischemia. The history and physical examination are important to narrow the source of acute or chronic problems, identify immediate interventions, and when necessary, facilitate emergency department care.

  8. Abdominal trauma

    The potential for multiple intraperitoneal and retroperitoneal organ injuries often makes accurate clinical evaluation of abdominal trauma patients difficult. Additionally, patients may be unresponsive, have unreliable abdominal physical examinations, or have concurrent serious head and cervical spine injuries which delay diagnosis of and attention to abdominal problems. In these situations radiologic abdominal imaging is often requested. To expedite patient evaluation, close cooperation between the emergency physician and the radiologist is essential. It is the clinical stability of the traumatized patient that dictates the extent of radiologic imaging. Life-threatening hypotension, positive peritoneal signs, or clear evidence of penetrating abdominal injury are indications for immediate surgery. Stable patients with signs suggesting intra-abdominal injury will benefit by further radiologic evaluation with appropriate imaging modalities. The selection of an appropriate modality in any one clinical situation depends upon many criteria including accessibility to diagnostic equipment, the sensitivity and specificity of each technique, and the expertise and preference of the attending radiologist. A suggested scheme for evaluating abdominal trauma patients is presented. Most aspects of this evaluation scheme will be discussed in depth

  9. Abdominal trauma

    Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

  11. Abdominal Sepsis.

    De Waele, Jan J

    2016-08-01

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

    The purpose of this article is to review and illustrate the spectrum of computed tomography (CT) appearances of abdominal tuberculosis. Tuberculosis can affect any organ or tissue in the abdomen, and can be mistaken for other inflammatory or neoplastic conditions. The most common sites of tuberculosis in the abdomen include lymph nodes, genitourinary tract, peritoneal cavity and gastrointestinal tract. The liver, spleen, biliary tract, pancreas and adrenals are rarely affected, but are more likely in HIV-seropositive patients and in miliary tuberculosis. This article should alert the radiologist to consider abdominal tuberculosis in the correct clinical setting to ensure timely diagnosis and enable appropriate treatment.

    Full Text Available Abdominal compartment syndrome with increased abdominal pressure resulted in multi-organ dysfunctions can be lethal in children. The open abdomen procedure intentionally leaves the abdominal cavity open in patients with severe abdominal sepsis and abdominal compartment syndrome by temporarily relieving the abdominal pressure. We reported our experience of open abdomen procedure in successfully treating a 4-year old boy with abdominal compartment syndrome caused by severe fungal peritonitis and sepsis after gastric perforation.

  16. Abdominal Burkitt lymphoma

    Purpose: As scarce information is available, in this research we have tried to describe the imaging findings of the Burkitt's lymphoma. Retrospective analysis of the clinical and imaging presentation of a 4 years old boy, is given. Biopsy confirmed the BL. Different imaging techniques were combined. The X-rays were negative. The US revealed a moderate hepatomegaly with multiple hypoechoic nodules and free fluid in the abdominal cavity. The CT showed the hepatomegaly as well as solid nodules in great number and different sizes(due to the densitometric behaviour and to post contrast enhancement), a scarce amount of ascites and a density increase of the mesentery fat. The MRI characterized and revealed in detail the US and the CT findings. The Burkitt's lymphoma is a rare entity; several methods are needed to approach the diagnosis. It represents a great clinical and imaging challenge. (author)

  17. Abdominal Burkitt lymphoma in children : CT finding

    To evaluate the CT findings of Burkitt's lymphoma involving the abdomen in children We retrospectively analyzed the abdominal CT of ten children who presented with abdominal symptom. They were confirmed by operation in two cases and by fine needle aspiration biopsy in eight to be suffering from Burkitt's lymphoma. We also abdominal ultrasonography(USG)(n=10) and carried out small bowel follow-through examination(SBS)(n=5). Analyses focused on features of the abdominal mass : bowel wall thickening, ascites, lymphadenopathy, and the involvement of intra-abdominal solid organ. Abdominal CT at the time of presentation showed a huge conglomerated mass encasing segments of small bowel and also peripherally displacing bowel loops(n=9), bowel wall thickening(n=10), and ascites(n=10). In three of these cases, we were able to see tumor necrosis and cavity formation. Extensive infiltration into mesenteric fat and obliteration of tissue plane made it impossible to identify on CT the margin of the tumor and the presence of mesenteric lymphadenopathy. In four patients, sonography showed enlarged mesenteric lymph nodes(15-20mm), and in three, retroperitoneal lymph nodes(5mm, 10mm, 12mm in long dimension) were detected on CT and USG. Abdominal CT can reveal the characteristic imaging features of Burkitt's lymphoma in children. These are a huge conglomerate mass with or without cavity formation, that encases the small bowel and infiltrates the mesentery, ascites, and the relatively spared retroperitoneal lymph nodes

  1. Abdominal trauma

    Radiologic evaluation of abdominal trauma must provide a quick and accurate assessment of the lesions in order to improve the management of the patient. The technique used varies depending on the mechanism of the trauma (blunt trauma or stab wounds) and the hemodynamic status. Radiologic evaluation is usually performed in blunt trauma whereas stab wound trauma is usually explored surgically. The various techniques available are standard radiographs, ultrasonography, computed tomography and arteriography. The role of magnetic resonance imaging in the immediate evaluation is still not well defined. It appears to be useful method in the delayed evaluation of diaphragmatic trauma. Computed tomography is the method most commonly performed in trauma patients. This technique is accurate and allows correct assessment of the lesions. The disadvantages are the radiation induced and the need for a hemo-dynamically stable patient. The aim of the radiologic evaluation is to provide the clinicians with an accurate description of the lesions. It can help in the management of the patient usually in association with clinical and laboratory data. It can also guide interventional procedures (drainage, embolization...). Finally, it allows radiographic follow-up when conservative treatment is performed. (authors). 26 refs., 11 figs., 1 tab

    con una fuente emisora de calor (resguardo caliente. Diversos autores han descrito la difusión del N2O para cavidades cerradas por métodos como cromatografia gaseosa y analizador de gases, que no permiten un estudio macroscópico detallado del gas. El presente estudio tubo como objetivo la filmación macroscópica en el espectro infrarrojo de la difusión de N2O, utilizado en anestesia inhalatoria, para la cavidad peritoneal de ratones sometidos a pneumoperitoneo de 20 mmHg con aire ambiente. MÉTODO: Los animales fueron divididos en tres grupos, de acuerdo con el anestésico utilizado: I- Control venoso: tiopental intra-peritoneal; II- Control inhalatorio: isoflurano a 1,2% en O2 100%; III- Óxido Nitroso: N2O 66% en oxígeno e isoflurano a 0,6%. Los termogramas provenientes de la descompresión abdominal fueron obtenidos, por medio de un radiómetro AGEMA 550 filmados a 7 cuadros por segundo. RESULTADOS: El N2O se demostró visible al infrarrojo. En el momento de la descompresión abdominal, no hubo en los grupos I y II termogramas con rastros de gases visibles al infrarrojo. Hubo, todavía, rastros de gases visibles al infrarrojo en el grupo III. CONCLUSIONES: Se concluye que el óxido nitroso inhalatorio a 66% se difundió para la cavidad peritoneal de ratones sometidos a pneumoperitoneo de 20 mmHg con aire ambiente, sin aumento de la presión intra-abdominal.BACKGROUND AND OBJECTIVES: Nitrous oxide (N2O, for its tri-atomic asymmetric structure, has high energy emission and absorption characteristics within the infrared spectrum, with maximum absorption at 4.5 µm, what makes it visible at short infrared, when contrasted with a heat emission source (hot support.

  6. [Intestinal occlusion and abdominal compartment syndrome (ACS)].

    Stagnitti, Franco

    2009-01-01

    Intestinal occlusion is defined as an independent predictive factor of intra-abdominal hypertension (IAH) which represents an independent predictor of mortality. Baggot in 1951 classified patients operated with intestinal occlusion as being at risk for IAH ("abdominal blow-out"), recommending them for open abdomen surgery proposed by Ogilvie. Abdominal surgery provokes IAH in 44.7% of cases with mortality which, in emergency, triples with respect to elective surgery (21.9% vs 6.8%). In particular, IAH is present in 61.2% of ileus and bowel distension and is responsible for 52% of mortality (54.8% in cases with intra-abdominal infection). These patients present with an increasing intra-abdominal pressure (IAP) which, over 20-25 mmHg, triggers an Abdominal Compartment Syndrome (ACS) with altered functions in some organs arriving at Multiple Organ Dysfunction Syndrome (MODS). The intestine normally covers 58% of abdominal volume but when there is ileus distension, intestinal pneumatosis develops (third space) which can occupy up to 90% of the entire cavity. At this moment, Gastro Intestinal Failure (GIF) can appear, which is a specific independent risk factor of mortality, motor of "Organ Failure". The pathophysiological evolution has many factors in 45% of cases: intestinal pneumatosis is associated with mucosal and serous edema, capillary leakage with an increase in extra-cellular volume and peritoneal fluid collections (fourth space). The successive loss of the mucous barrier permits a bacterial translocation which includes bacteria, toxins, pro-inflammatory factors and oxygen free radicals facilitating the passage from an intra-abdominal to inter-systemic vicious cyrcle. IAH provokes the raising of the diaphragm, and vascular and visceral compressions which induce hypertension in the various spaces with compartmental characteristics. These trigger hypertension in the renal, hepatic, pelvic, thoracic, cardiac, intracranial, orbital and lower extremity areas, giving

  7. Abdominal MRI in childhood

    MRI provides diagnostic information in multiple abdominal diseases in childhood. Additional information to sonographic findings can be achieved in the diagnosis of abdominal malformation as well as in several inflammatory processes. In childhood cancer imaging MRI is essential at the beginning as well as during therapy to assess response to therapy. Because of radiation protection MRI has to replace CT in abdominal imaging in children. Some technical details have to be considered when children are examined. (orig.)

    Background: Abdominal desmoid tumor is one of the forms of deep (musculoaponeurotic) fibromatosis. It occurs more often as a desmoid tumor in the abdominal wall, less often in various intra-abdominal locations. In this work, we performed retrospective study concerning diagnostic problems of this disease with the use of imaging techniques. Method: Four patients (three females and one male) were examined by postcontrast CT (computed tomography) and one of them also by MR (magnetic resonance). All findings were correlated with the operational findings and histologic examination. Results: The findings were typical only in the case with the lesion located in the abdominal wall, three described cases of the intra-abdominal desmoid provided a broad range of differentially diagnostic possibilities (metastases, GIT tumors, lymphomas, etc.). In particular, the findings in infiltrative processes in intra-abdominal location and retroperitoneal involvement were less typical. Ultimately, the histological findings were decisive. Conclusion: The possibility of the occurrence of intra-abdominal desmoid tumor must be considered particularly in younger individuals with rapidly growing tumorous process, which does not immediately arise from the surrounding organs (digestive tract, internal genitalia, etc.), and is located in the abdominal wall or in the abdominal cavity.

Nowadays laparoscopy has become an accepted practice in hemodynamically stable patient without signs of peritonitis. We report a case of a lower anterior abdominal gunshot patient treated laparoscopically. A 32-year-old male presented to the Emergency Department with complaint of gunshot penetrating injury at left lower anterior abdominal wall. The patient had no symptoms or obvious bleeding and was vitally stable. On examination we identified 1 cm diameter entry wound at the left lower abdominal wall. The imaging studies showed the bullet in the peritoneal cavity but no injured intraperitoneal and retroperitoneal viscera. We decided to remove the bullet laparoscopically. Twenty-four hours after the intervention the patient was discharged. The decision for managing gunshot patients should be based on clinical and diagnostic findings. Anterior abdominal injuries in a stable patient without other health problems can be managed laparoscopically.

    Full Text Available Neonatal abdominal masses have broad spectrum of pathology, ranging from small lesions found incidentally to large masses occupying the entire of peritoneal cavity. These tumors are benign to malignant, and from unilocular cysts to complex solid lesions. Many of these lesions identified and will treat before delivery. Others are discovered during routine examination. These lesions may be life threatening, or cause persistent morbidity. Some of these have no sequel."nDiagnosis began with history. Characteristic of the mass which must be note include location, size, shape, texture, mobility and tenderness. Other findings should be in mind to find out nature of mass, for example hypoplasia of chest wall with oligohydramnios due to GU tract obstruction (potter sequwnce, a bulging hymen due to hydrometrocolpus, skin metastasis due to neuroblastoma. Radiography is the next step that shows organomegaly and calcification. Next step is US which is an excellent screening tool. CT and MRI are occasionally indicated."nThe purpose of this presentation is to review the diagnosis of abdominal masses in neonates.

  12. [Abdominal pregnancy, institutional experience].

    Bonfante Ramírez, E; Bolaños Ancona, R; Simón Pereyra, L; Juárez García, L; García-Benitez, C Q

    1998-07-01

    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy. PMID:9737070

The acceleration was produced by microwave electric oscillations at 352 MHz. The electrons and positrons were grouped into bunches, like beads on a string, and the copper sphere at the top stored the microwave energy between the passage of individual bunches. This made for valuable energy savings as it reduced the heat generated in the cavity.

  19. Abdominal tuberculosis: Imaging features

    Radiological findings of abdominal tuberculosis can mimic those of many different diseases. A high level of suspicion is required, especially in high-risk population. In this article, we will describe barium studies, ultrasound (US) and computed tomography (CT) findings of abdominal tuberculosis (TB), with emphasis in the latest. We will illustrate CT findings that can help in the diagnosis of abdominal tuberculosis and describe imaging features that differentiate it from other inflammatory and neoplastic diseases, particularly lymphoma and Crohn's disease. As tuberculosis can affect any organ in the abdomen, emphasis is placed to ileocecal involvement, lymphadenopathy, peritonitis and solid organ disease (liver, spleen and pancreas). A positive culture or hystologic analysis of biopsy is still required in many patients for definitive diagnosis. Learning objectives:1.To review the relevant pathophysiology of abdominal tuberculosis. 2.Illustrate CT findings that can help in the diagnosis

  1. CT diagnosis of concealed rupture of intestine following abdominal trauma

    Objective: To investigate CT findings of concealed rupture of intestine following abdominal trauma. Methods: CT findings of 11 cases with concealed rupture of intestine following abdominal trauma proved by surgery were identified retrospectively. Results: The main special signs included: (1) Free air in 4 cases, mainly around injured small bowel or under the diaphragm, or in the retroperitoneal space or and in the lump. (2) High density hematoma between the intestines or in the bowel wall (4 cases). (3) Bowel wall injury sign, demonstrated as low density of the injured intestinal wall, attenuated locally but relatively enhanced in neighbor wall on enhanced CT. (4) Lump around the injured bowel wall with obvious ring-shaped enhancement (4 cases). Other signs included: (1) Free fluid in the abdominal cavity or between the intestines with blurred borders. (2) Bowel obstruction. Conclusion: CT is valuable in diagnosing concealed rupture of intestine following abdominal trauma. (authors)

  2. Aggressive malignant abdominal mesothelioma: Clinical report

    A 32-year-old Filipino female, working as an x-ray technician, presented to the Emergency Room (ER) with acute abdominal pain for one day. The pain was mainly on the left side and left hypochondrium. She had recurring abdominal pain before but not significant to worry her. She also complained of abdominal distension, which she noticed one week ago. Abdominal examination revealed fullness in the left hypochondrium with marked tenderness but negative rebound. Abdominal ultrasound (US) showed a huge mass mainly in the left hypochondrium. The origin of the mass cannot be identified by US. A computerized tomography scan showed a mass in the left side of the abdomen crossing the midline with a necrotic centre. The hospital course of the patient runs smoothly, and she was discharged after 7-days and referred to an Oncology Center. Abdominal mesothelioma is a neoplasm arising from the mesothelial surface lining the abdominal cavity. It is less frequent than that of the pleura. It is a rapidly growing and fatal malignancy with a median survival of less than 1-year. The relation between pleural malignant mesothelioma and asbestos is well recognized since it was described in 19602 but implication of asbestos exposure in the etiology of the peritoneal type is less obvious. This patient history is giving no obvious exposure to asbestos but as she is working in the Radiology Department as an x-ray technician she is well exposed to x-ray, but the effect of radioactivity on induction of mesothelioma is still disputed.4 There are several reports linking malignant mesothelioma to radioactivity due to radiation therapy.The fibrous mesothelioma (sarcomatous), as in this case, which is difficult to diagnose microscopically, looks like a fibroma, unless helped by tissue culture. The treatment options of malignant mesothelioma include surgery, intraperitoneal chemotherapy and whole abdominal radiation or multimodality therapy, which were suggested that might prolong the survival in

    On the inside of the cavitytThere is a layer of niobium. Operating at 4.2 degrees above absolute zero, the niobium is superconducting and carries an accelerating field of 6 million volts per metre with negligible losses. Each cavity has a surface of 6 m2. The niobium layer is only 1.2 microns thick, ten times thinner than a hair. Such a large area had never been coated to such a high accuracy. A speck of dust could ruin the performance of the whole cavity so the work had to be done in an extremely clean environment.

  4. Abdominal Dual Energy Imaging

    Sommer, F. Graham; Brody, William R.; Cassel, Douglas M.; Macovski, Albert

    1981-11-01

    Dual energy scanned projection radiography of the abdomen has been performed using an experimental line-scanned radiographic system. Digital images simultaneously obtained at 85 and 135 kVp are combined, using photoelectric/Compton decomposition algorithms to create images from which selected materials are cancelled. Soft tissue cancellation images have proved most useful in various abdominal imaging applications, largely due to the elimination of obscuring high-contrast bowel gas shadows. These techniques have been successfully applied to intravenous pyelography, oral cholecystography, intravenous abdominal arteriog-raphy and the imaging of renal calculi.

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two

  7. Abdominal Vascular Catastrophes.

    Singh, Manpreet; Koyfman, Alex; Martinez, Joseph P

    2016-05-01

    Abdominal vascular catastrophes are among the most challenging and time sensitive for emergency practitioners to recognize. Mesenteric ischemia remains a highly lethal entity for which the history and physical examination can be misleading. Laboratory tests are often unhelpful, and appropriate imaging must be quickly obtained. A multidisciplinary approach is required to have a positive impact on mortality rates. Ruptured abdominal aortic aneurysm likewise may present in a cryptic fashion. A specific type of ruptured aneurysm, the aortoenteric fistula, often masquerades as the more common routine gastrointestinal bleed. The astute clinician recognizes that this is a more lethal variant of gastrointestinal hemorrhage. PMID:27133247

  9. Report of a Case of Primary Abdominal Pregnancy

    Sh Beigi

    2006-01-01

    Full Text Available Ectopic pregnancy (EP is a potentially life-threatening condition in which the embryo implants outside the uterine endometrial cavity. Abdominal pregnancy is an atypical site wherein the product of conception lies totally outside the reproductive tract. Primary abdominal pregnancy is a very rare condition with a high mortality rate. Diagnosis is often late or misdiagnosed. The aim of introducing this case report is to present a new case of early primary abdominal pregnancy. Despite regular menstrual bleeding and contraception with IUD (intrauterine device, this pregnancy occurred in a 24-year old woman. Emergency laparotomy was performed because of abdominal pain, unstable condition and positive urine pregnancy test. It revealed more than 1500 ml of blood in the abdominal cavity. The uterus, both fallopian tubes and ovaries were completely intact. A 3X4 cm mass lateral to the left utersacral ligament was observed and resected. Since IUD strings could not be identified, endometrial currettage was performed and then the IUD was removed. Histological report of the mass and tissue of uterine cavity was placental villi and secretory endometrium, respectively, which according to Studdifords criteria is a new case of early primary abdominal pregnancy. To reduce maternal mortality and morbidity, early recognition of ectopic pregnancy is critical. According to review of the literature and the case report, a high index of suspicion is vital for the early diagnosis of ectopic pregnancy because the signs and symptoms of EP overlap with many surgical and gynecologic conditions. With early diagnosis of EP, we can suggest many therapeutic options and also retain fertility (if desired by patient, while minimizing disease and treatment-related morbidity.

  11. Adult abdominal hernias.

    Murphy, Kevin P

    2014-06-01

    Educational Objectives and Key Points. 1. Given that abdominal hernias are a frequent imaging finding, radiologists not only are required to interpret the appearances of abdominal hernias but also should be comfortable with identifying associated complications and postrepair findings. 2. CT is the imaging modality of choice for the assessment of a known adult abdominal hernia in both elective and acute circumstances because of rapid acquisition, capability of multiplanar reconstruction, good spatial resolution, and anatomic depiction with excellent sensitivity for most complications. 3. Ultrasound is useful for adult groin assessment and is the imaging modality of choice for pediatric abdominal wall hernia assessment, whereas MRI is beneficial when there is reasonable concern that a patient\\'s symptoms could be attributable to a hernia or a musculoskeletal source. 4. Fluoroscopic herniography is a sensitive radiologic investigation for patients with groin pain in whom a hernia is suspected but in whom a hernia cannot be identified at physical examination. 5. The diagnosis of an internal hernia not only is a challenging clinical diagnosis but also can be difficult to diagnose with imaging: Closed-loop small-bowel obstruction and abnormally located bowel loops relative to normally located small bowel or colon should prompt assessment for an internal hernia.

  14. PET/CT Interpretation: Abdominal Anatomy

    Detail knowledge of abdominal anatomy is essential for accurate interpretation of oncologic PET/CT. The objective of this lecture is to provide the core knowledge and guidance about, peritoneal cavity, vessels, nodal, internal organ, especially liver segmental anatomy, and retroperitoneal spaces to nuclear medicine physicians in their interpretation of oncologic PET/CT. Peritoneal Cavity: The peritoneal spaces are easiest to recognize when there is ascites. The right subphrenic space communicates with anterior and posterior subhepatic (Morrison's) space. The left subphrenic space freely communicate with the left subhepatic space. The right and left subphrenic spaces are separated by falciform ligament and do not communicate directly. The lesser sac is the isolated peritoneal compartment between the stomach and pancreas. It communicates with the rest of the peritoneal cavity (greater sac) through the Foramen of Winslow. The right subphrenic and subhepatic spaces communicate freely with the pelvic peritoneal cavity thru the right paracolic gutter. The phrenicocolic ligament prevents free communication between the left subphrenic / subhepatic space and left paracolic gutter. Free fluid and peritoneal metastases commonly settles in pelvis as the most dependent portion of the peritoneal cavity. The small mesentery suspends the jejunum and ileum and extends obliquely from the left upper quadrant to right lower quadrant. Disease originating above the ligament is directed towards the right lower quadrant and below the ligament can spread to pelvis. The greater omentum hangs from the greater curvature of the stomach and descends in front of the abdominal viscera and serves as a fertile ground for peritoneal metastases. Vessels: The abdominal aorta descends anterior to the left side of the spine to its bifurcation at the level of the iliac crest. The normal aorta does not exceed 3 cm diameter and tapers progressively as it descends distally. The common iliac arteries

  15. [Intra-abdominal infection and new quinolones].

    Gnocchi, C A

    1999-01-01

    Intra-abdominal infection is defined as the presence of an infectious process within the peritoneal cavity. It may be local or have a systemic consequence generating multiple organic disfunction. Most of the studies report a mortality of 30% in severe intra-abdominal infection. Secondary peritonitis is caused by the loss of integrity of the gastrointestinal apparatus, which contaminates with pathogens the peritoneal cavity. Invariably they are polymicrobial infections, mostly due to facultative anaerobic and anaerobic Gram negative bacilli. Prognosis of peritonitis depends on the struggle between two forces: local and systemic immunity of the host and the volume, nature and length of the contamination. Microorganisms and their products estimulate cellular defenses in the host and activate numerous inflammatory mediators responsible for sepsis. Antibiotic treatment of secondary peritonitis must act mainly against Escherichia coli and Bacteroides fragilis. The adequate and early empirical administration of antibiotics against these bacteria is well established. It is necessary to consider if the infection is localized or generalized and if it is accompanied or not by organic disfunction. It also has to be taken into account if peritonitis is community or hospital-acquired when choosing the antibiotic scheme. In community-acquired peritonitis with low to moderate infections a combination of metronidazole-ceftriaxone, metronidazole-gentamycin or a monodrug like ampicillin-sulbactam may be used. In severe hospital-acquired peritonitis imipenem or the combination piperacillin-tazobactam are effective. New quinolones such as trovafloxacin or clinafloxacin, with excellent activity against aerobes and anaerobes producing intra-abdominal infections, may be effective. Future clinical trials are needed to determine their utility. Tertiary peritonitis represent a systemic inflammatory response with multiorganic failure due to the uncontrolled activation of the inflammatory

  16. Athletic injuries of the lateral abdominal wall: review of anatomy and MR imaging appearance

    The lateral abdominal wall is comprised of three muscles, each with a different function and orientation. The transversus abdominus, internal oblique, and external oblique muscles span the abdominal cavity between the iliocostalis lumborum and quadratus lumborum posteriorly and the rectus abdominis anteriorly. The lateral abdominal wall is bound superiorly by the lower ribs and costal cartilages and inferiorly by the iliac crest and inguinal ligament. The lateral abdominal wall may be acutely or chronically injured in a variety of athletic endeavors, with occasional acute injuries in the setting of high-energy trauma such as motor vehicle collisions. Injuries to the lateral abdominal wall may result in lumbar hernia formation, unique for its high incarceration rate, and also Spigelian hernias. This article will review the anatomy, the magnetic resonance (MR) imaging approach, and the features and complications of lateral abdominal wall injuries. (orig.)

    Choi, Ji Bai; Ko, Young Tae; Yoon, Yup; Lim, Jae Hoon; Kim, Soon Yong [Kyung Hee University Hospital, Seoul (Korea, Republic of)

    1985-12-15

    Authors analysed CT findings of 8 patients with tuberculous lymphadenitis and one case of tuberculous abscess diagnosed surgically or clinically. The results were as follows; 1. Soft tissue density masses were noted in 8 patients in paraaortic, mesenteric, peripancreatic, celiac, portahepatis, and esophagogastric junction areas in order of frequency, and these correspond to lymph node groups of the same name. On contrast enhanced CT, rim enhancement with multilocular low densities indicating caseous necrosis were not noted in 3 patients, ill defined low densities were seen in 3 patients, and no definite changes were noted in 2 patients. 2. Two or more lymph node groups were involved in 6 patients, and one lymph node group was involved in two patients. 3. A huge cystic mass with relatively irregular rim enhancement and small amount of solid component occupied nearly entire upper abdomen in 1 patient and this was confirmed as tuberculous abscess in peritoneum. 4. In 2 cases, bowel wall thickening was suggested in cecum, ascending colon, and terminal ileum.

    2005-01-01

    Objective: To explore the characteristics of closed abdominal injury in pregnancy women and its treatment.Methods: The clinical data of 37 pregnancy patients with closed abdominal injury treated in our hospital from June 1993 to June 2003 were collected and analyzed.Results: All the 37 patients were treated with operation. Among them 2 early pregnancy patients with intestinal rupture and 1 patient with retroperitoneal hematoma were treated under laparoscope; in other 34 pregnancy patients laparotomy was performed. Of the 34 patients 8 used cesarean section because premature separation of placenta and enlarged womb interrupted the management of intra-abdominal organ injury. In the 37 patients 33 (89.1%) were cured, 4 (10.8%) die, postoperative complication rate was 16.2% (6/37). Two patients (5.4%) suffered from abdominal cavity infection, 3 (8.1%) from pulmonary infection, and 1 (2.7%) had multi-organ failure.Conclusions: For pregnancy patients with closed abdominal injury, besides obsteric diseases intra-abdominal injury should be given much attention. Accurate diagnosis and timely treatment can gain the time to save the life of both mother and fetus.

  1. Component separation in abdominal trauma.

    2014-01-01

    Component separation is established for complex hernia repairs. This case presents early component separation and release of the anterior and posterior sheath to facilitate closure of the abdominal wall following emergency laparotomy, reinforcing the repair with a biological mesh. On Day 11 following an emergency laparotomy for penetrating trauma, this patient underwent component separation and release of the anterior and posterior sheath. An intra-abdominal biological mesh was secured, and the fascia and skin closed successfully. Primary abdominal closure can be achieved in patients with penetrating abdominal trauma with the use of component separation and insertion of intra-abdominal biological mesh, where standard closure is not possible.

  2. CT of abdominal trauma

    Soon after it became available for clinical use, cranial CT became the method of choice for evaluating head trauma. Only relatively recently have newer generation full-body scanners been installed at major trauma centers, but experience is rapidly being gained in the utilization of CT for abdominal trauma. CT has proved highly accurate in diagnosing a wide variety of injuries to both intra- and retroperitoneal organs in pediatric and adult patient populations. The impact has been evident not only in decreasing utilization of other diagnostic tests, such as angiography, but also in practical management decisions, such as whether to perform exploratory laparotomy. This chapter details the authors' approach to evaluation of abdominal trauma by CT

  3. The blunt abdominal trauma

    Up to 1970 the number of patients suffering from blunt abdominal trauma showed a substantial increase. In more than 50% of all cases there are additional injuries. The most important factor influencing the prognosis of these patients is the early and correct indication for operation and the avoidance of unnecessary laparotomies. As a primary aim in diagnosis one should consider the recognition of an intraperitoneal bleeding without risk for the patient. Peritoneal lavage as an invasive method with low complication rates has proved good. First reports also show good results using the sonography of the abdomen. The recognition of the injured organ allows a carefully directed operation. Concerning the prognosis it is of minor importance. The diagnosis in patients with blunt abdominal trauma at the university clinic of Freiburg consists of: sonography, followed in positive cases by laparotomy or angiography and laparotomy. In cases with questionable results a lavage is done. (orig.)

  5. The abdominal circulatory pump.

    Andrea Aliverti

    Full Text Available Blood in the splanchnic vasculature can be transferred to the extremities. We quantified such blood shifts in normal subjects by measuring trunk volume by optoelectronic plethysmography, simultaneously with changes in body volume by whole body plethysmography during contractions of the diaphragm and abdominal muscles. Trunk volume changes with blood shifts, but body volume does not so that the blood volume shifted between trunk and extremities (Vbs is the difference between changes in trunk and body volume. This is so because both trunk and body volume change identically with breathing and gas expansion or compression. During tidal breathing Vbs was 50-75 ml with an ejection fraction of 4-6% and an output of 750-1500 ml/min. Step increases in abdominal pressure resulted in rapid emptying presumably from the liver with a time constant of 0.61+/-0.1SE sec. followed by slower flow from non-hepatic viscera. The filling time constant was 0.57+/-0.09SE sec. Splanchnic emptying shifted up to 650 ml blood. With emptying, the increased hepatic vein flow increases the blood pressure at its entry into the inferior vena cava (IVC and abolishes the pressure gradient producing flow between the femoral vein and the IVC inducing blood pooling in the legs. The findings are important for exercise because the larger the Vbs the greater the perfusion of locomotor muscles. During asystolic cardiac arrest we calculate that appropriate timing of abdominal compression could produce an output of 6 L/min. so that the abdominal circulatory pump might act as an auxiliary heart.

    2013-01-01

    Full Text Available Abdominal elephantiasis is a rare entity. Abdominal elephantiasis is an uncommon, but deformative and progressive cutaneous disease caused by chronic lymphedema and recurrent streptococcal or Staphylococcus infections of the abdominal wall. We present 3 cases of patients with morbid obesity who presented to our hospital with abdominal wall swelling, thickening, erythema, and pain. The abdominal wall and legs were edematous, with cobblestone-like, thickened, hyperpigmented, and fissured plaques on the abdomen. Two patients had localised areas of skin erythema, tenderness, and increased warmth. There was purulent drainage from the abdominal wall in one patient. They were managed with antibiotics with some initial improvement. Meticulous skin care and local keratolytic treatment for the lesions were initiated with limited success due to their late presentation. All three patients refused surgical therapy. Conclusion. Early diagnosis is important for the treatment of abdominal elephantiasis and prevention of complications.

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

    2014-01-01

    Full Text Available We observed the inhibitive effect of electroacupuncture (EA at Zusanli on inflammatory mediators of postoperative intra-abdominal adhesions to find out the relationship between EA and the cholinergic anti-inflammatory pathway. Sixty-four rats were divided into 8 groups (A–H, each = 8: A = sham control; B = abdominal adhesions model; C = abdominal adhesions plus EA; D = sham acupoint control; E = abdominal adhesions plus vagotomy; F = abdominal adhesions plus EA after vagotomy; G = abdominal adhesions plus α-bungarotoxin (BGT; and H = abdominal adhesions plus EA after α-BGT. α-BGT (1 μg/kg was injected into the abdominal cavity after surgery, and the bilateral celiac vagotomy was done during the surgery. On the third day the levels of inflammatory mediators (TNF-α, nitric oxide (NO, and nitric oxide synthase (NOS in tissues were evaluated. The abdominal adhesion groups developed obvious edema. Compared with sham control, the abdominal adhesion resulted in a significant elevation of inflammatory mediators. EA lowered the elevated levels of inflammatory mediators significantly; EA plus α-BGT and vagotomy showed less anti-inflammatory effects. The activation of the cholinergic anti-inflammatory pathway might be one of the mechanisms of EA at Zusanli acupoints to exert the anti-inflammatory effects.

  11. Cavity magnomechanics

    Zou, Chang-Ling; Zhang, Xufeng; Jiang, Liang; Tang, Hong

    2016-05-01

    Recently, cavity magnonics has attracted much attention for potential applications of coherent information transduction and hybrid quantum devices. The magnon is a collective spin wave excitation in ferromagnetic material. It is magnetically tunability, with long coherence time and non-reciprocical interaction with electro-magnetic fields. We report the coherent coupling between magnon, microwave photon and phonon. First, we demonstrate strong coupling and ultrastrong coupling between the magnon in YIG sphere and microwave photon in three-dimensional cavity. Then, based on the hybridized magnon-photon modes, we observe the triply resonant magnon-mcirowave photon-phonon coupling, where the ultrahigh-Q mechanical vibration of YIG sphere is dispersively coupled with the magnon via magnetostrictive interaction. We observe interesting phenomena, including electromagnetically induced transparency/absorption and parametric amplification. In particular, benefit from the large tunability of the magnon, we demonstrate a tunable microwave amplifier with gain as high as 30 dB. The single crystal YIG also has excellent optical properties, and thus provide a unique platform bridging MHz, GHz and THz information carriers. Finally, we present the latest progress towards coherent magnon to optical photon conversion.

    Full Text Available We report and discuss a case of primary hydatidosis of the pelvic cavity in a woman who presented with severe weight loss and abdominal pain. This unusual presentation was initially considered as a tumor process until surgical exploration and microscopic studies confirmed the diagnosis. The gynecologists should be aware of possibility of primary hydatid cyst of the pelvic cavity and should be considered in the differential diagnosis of cystic pelvic masses, especially in areas where the disease is endemic.

  14. [Differential diagnosis of abdominal pain].

    Frei, Pascal

    2015-09-01

    Despite the frequency of functional abdominal pain, potentially dangerous causes of abdominal pain need to be excluded. Medical history and clinical examination must focus on red flags and signs for imflammatory or malignant diseases. See the patient twice in the case of severe and acute abdominal pain if lab parameters or radiological examinations are normal. Avoid repeated and useless X-ray exposure whenever possible. In the case of subacute or chronic abdominal pain, lab tests such as fecal calprotectin, helicobacter stool antigen and serological tests for celiac disease are very useful. Elderly patients may show atypical or missing clinical signs. Take care of red herrings and be skeptical whether your initial diagnosis is really correct. Abdominal pain can frequently be an abdominal wall pain. PMID:26331201

  16. Hypnosis for functional abdominal pain.

    Gottsegen, David

    2011-07-01

    Chronic abdominal pain is a common pediatric condition affecting 20% of the pediatric population worldwide. Most children with this disorder are found to have no specific organic etiology and are given the diagnosis of functional abdominal pain. Well-designed clinical trials have found hypnotherapy and guided imagery to be the most efficacious treatments for this condition. Hypnotic techniques used for other somatic symptoms are easily adaptable for use with functional abdominal pain. The author discusses 2 contrasting hypnotic approaches to functional abdominal pain and provides implications for further research. These approaches may provide new insights into this common and complex disorder. PMID:21922712

    2009-04-01

    Full Text Available Abstract Hydatid disease, caused by Echinococcus granulosus, is a common parasitic infection of the liver. Disseminated intra-abdominal hydatid disease may occur following rupture of the hydatid cyst into the peritoneal cavity, producing secondary echinococcosis. Rarely cyst may develop de-novo in the peritoneal cavity without involvement of any other intra-abdominal organs. We present a unique case of 56-year-old woman with a primary intraabdominal hydatid cyst in the right iliac fossa masquerading as appendicular lump.

  19. Practical pediatric abdominal CT

    This course is designed to help the radiologist in a hospital setting successfully approach abdominal CT in the infant and child. Emphasis is placed on techniques necessary for a high-quality examination of the upper abdomen, as applied to common pediatric problems such as trauma, tumor, and infection. Material is presented on technical considerations, including patient sedation, preparation, and potential pitfalls and helpful hints for imaging. An emphasis is placed on dynamic scanning with table incrementation. The section on trauma focuses on an approach to imaging the abdomen in the injured child, typical injuries, patterns of injury in the upper abdomen, and why CT is the best imaging modality for blunt upper abdominal trauma. The discussion of tumor imaging reviews the appearance of typical childhood neoplasia including Wilms tumor, neuroblastoma, non-Hodgkin and Burkitt lymphoma, and disseminated solid tumors such as rhabdomyosarcoma. The authors emphasize what to look for and where, both on initial and on later (for recurrences) examinations. The discussion of infection addresses detection of abscesses and occult infections in children, as well as imaging of abscesses prior to intervention

  20. [BIOLOGICAL IMPLANTS IN ABDOMINAL WALL HERNIA REPAIR (REVIEW)].

    Abatov, N; Badyrov, R; Abatova, A; Assamidanov, E; Kaukenov, B

    2016-02-01

    The use of synthetic meshes as a material for abdominal wall hernia repair does not always ensure a recurrence-free treatment outcome and full recovery of the abdominal wall functional activity. There are well-known disadvantages such as poor resistance to infection, the infiltrate formation in the place of implantation, expressed adhesive process in cases of introperitoneal fixation, to create certain restrictions on the using of these implants for abdominal wall reconstruction. The search for alternative materials that could minimize the risk of complications, has led to the study of biological grafts. It is known that various methods for the manufacturing biological implants determine endogenous properties for each material separately, and may be cause a variety of biological responses in vivo after implantation. The question has not been resolved, what the fresh raw material is better to use for derive biological implants. In this review we investigated the interaction of different types of biological implants between the abdominal wall and the organs of abdominal cavity of the recipient, their ability to resist infection and the development of relapses, as a leading indicator of the effectiveness of hernioplasty.

    2014-01-01

    Full Text Available The meeting of the Publication "Evidence Based Telemedicine - Trauma and Emergency Surgery" (TBE-CiTE, through literature review, selected three recent articles on the treatment of victims stab wounds to the abdominal wall. The first study looked at the role of computed tomography (CT in the treatment of patients with stab wounds to the abdominal wall. The second examined the use of laparoscopy over serial physical examinations to evaluate patients in need of laparotomy. The third did a review of surgical exploration of the abdominal wound, use of diagnostic peritoneal lavage and CT for the early identification of significant lesions and the best time for intervention. There was consensus to laparotomy in the presence of hemodynamic instability or signs of peritonitis, or evisceration. The wound should be explored under local anesthesia and if there is no injury to the aponeurosis the patient can be discharged. In the presence of penetration into the abdominal cavity, serial abdominal examinations are safe without CT. Laparoscopy is well indicated when there is doubt about any intracavitary lesion, in centers experienced in this method.

  2. Nontraumatic abdominal emergencies: acute abdominal pain: diagnostic strategies

    Marincek, B. [Institute of Diagnostic Radiology, University Hospital Zurich, Raemistrasse 100, 8091 Zurich (Switzerland)

    2002-09-01

    Common causes of acute abdominal pain include appendicitis, cholecystitis, bowel obstruction, urinary colic, perforated peptic ulcer, pancreatitis, diverticulitis, and nonspecific, nonsurgical abdominal pain. The topographic classification of acute abdominal pain (pain in one of the four abdominal quadrants, diffuse abdominal pain, flank or epigastric pain) facilitates the choice of the imaging technique. The initial radiological evaluation often consists of plain abdominal radiography, despite significant diagnostic limitations. The traditional indications for plain films - bowel obstruction, pneumoperitoneum, and the search of ureteral calculi - are questioned by helical computed tomography (CT). Although ultrasonography (US) is in many centers the modality of choice for imaging the gallbladder and the pelvis in children and women of reproductive age, CT is considered to be one of the most valued tools for triaging patients with acute abdominal pain. CT is particularly beneficial in patients with marked obesity, unclear US findings, bowel obstruction, and multiple lesions. The introduction of multidetector row CT (MDCT) has further enhanced the utility of CT in imaging patients with acute abdominal pain. (orig.)

    2014-01-01

    A relatively new surgical technique allows for sutureless closure of a gastroschisis defect. Immediately after birth, a long umbilical cord stump is temporarily inverted into the abdominal cavity and later retracted and used to close the abdominal wall defect. Knowledge of this entity is important since the inverted umbilical cord simulates an intra-abdominal mass on cross-sectional imaging. While this procedure is well described in the surgical literature, the imaging features of inverted umbilical cord have yet to be reported. The case presented here highlights the sonographic imaging findings of the umbilical cord during the intestinal decompression phase of sutureless repair of gastroschisis. PMID:23907187

  4. The value of ultrasonography and computed tomography in the blunt abdominal trauma: a prospective study

    From August to December 1988, eleven patients with abdominal trauma, hemodynamically stable, were studied at Souza Aguiar Municipal Hospital in Rio de Janeiro, Brazil. After physical evaluation and initial resuscitation, these patients underwent abdominal paracentesis, basic roentgenographic examination and computed tomography. Either a conservative treatment or an exploratory laparotomy was carried out regarding the results of the examination. The use of ultrasound and computed tomography examination in patients with doubtful diagnosis proved to be effective and enable us to identify not only intra-abdominal and retroperitoneal lesions but also the presence of liquid collections in the peritoneal cavity.

The masculine sex prevailed with 38 patients (92,7 % and as much the open trauma as the closed one were more frequent in this sex with 25 patients (96,2 % and 13 patients (86,7 % respectively. They didn't show visceral damage during the laparoscopy 93, 3 % of the patients with closed abdominal trauma by what the surgical treatment was avoided, the same as in the patients with open abdominal trauma which had a non penetrating damage in abdominal cavity (80, 8 %. Conclusion: laparoscopic diagnosis is a useful test in patients with abdominal trauma and it avoids a considerable number of unnecessary conventional surgical treatment.

  6. Cavity magnomechanics

    Zhang, Xufeng; Zou, Changling; Jiang, Liang; Tang, Hong X.

    Mechanical oscillators have been recently widely utilized to couple with optical and microwave photons in a variety of hybrid quantum systems, but they all lack the tunability. The magnetostrictive force provides an alternative mechanism to allow phonon to couple with a different type of information carrier-magnon, the collective excitation of magnetization whose frequency can be tuned by a bias magnetic field. Here, we demonstrate an intriguing hybrid system that consists of a magnonic, a mechanical, and a microwave resonator. The magnon-phonon interaction results in hallmark coherent phenomena such as magnomechanically induced transparency/absorption and magnomechanical parametric amplification. The magnetic field dependence of magnon provides our system with unprecedented tunability. Moreover, the great flexibility of our system allows us to achieve triple resonance among magnon, phonon and photon, which drastically enhances the magnomechanical interaction. Our work demonstrates the fundamental principle of cavity magnetomechanics, opening up great opportunities in various applications, such as tunable microwave filter and amplifier, long-lifetime quantum memories, microwave-to-optics conversion.

  7. Abdominal lymphadenopathy detection using random forest

    Cherry, Kevin M.; Wang, Shijun; Turkbey, Evrim B.; Summers, Ronald M.

    2014-03-01

    We propose a new method for detecting abdominal lymphadenopathy by utilizing a random forest statistical classifier to create voxel-level lymph node predictions, i.e. initial detection of enlarged lymph nodes. The framework permits the combination of multiple statistical lymph node descriptors and appropriate feature selection in order to improve lesion detection beyond traditional enhancement filters. We show that Hessian blobness measurements alone are inadequate for detecting lymph nodes in the abdominal cavity. Of the features tested here, intensity proved to be the most important predictor for lymph node classification. For initial detection, candidate lesions were extracted from the 3D prediction map generated by random forest. Statistical features describing intensity distribution, shape, and texture were calculated from each enlarged lymph node candidate. In the last step, a support vector machine (SVM) was trained and tested based on the calculated features from candidates and labels determined by two experienced radiologists. The computer-aided detection (CAD) system was tested on a dataset containing 30 patients with 119 enlarged lymph nodes. Our method achieved an AUC of 0.762+/-0.022 and a sensitivity of 79.8% with 15 false positives suggesting it can aid radiologists in finding enlarged lymph nodes.

  8. Differential diagnosis of pelvic cavities containing gas and fluids

    Since untreated intra-abdominal abscesses are associated with a high mortality rate, early diagnosis is important. In abscesses involving gas formation, plain radiographs of the abdomen in various projections are sufficient for diagnosis.

  11. Penetrating abdominal trauma.

    Henneman, P L

    1989-08-01

    The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

  12. Economics of abdominal wall reconstruction.

    Bower, Curtis; Roth, J Scott

    2013-10-01

    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

  13. Automated recognition of body cavities in torso X-ray CT images

    Recently, it has become even more important to understand the normal anatomical structures of the human body in the field of radiological image anatomy. The recognition of body cavities is useful when organ extraction is performed. However, it is difficult to perform organ extraction and to obtain a clear understanding of anatomical structures based on CT values. For example, the distributions of the CT numbers of muscle and organs overlap each other. Therefore, the recognition of the body cavity domain can reduce the range of internal organ extraction and simplify organ segmentation. The purpose of the present study was to develop an automated method for recognizing the body cavities in torso X-ray CT images. Our body cavity recognition method is based on skeletal positions and is performed by extracting the borders of the thoracic cavity, abdominal cavity, and pelvic cavity. This method detects the initial and final points of such borders and searches for the shortest path on the surfaces of the skeletal structures. It then generates the boundary surfaces of the thoracic, abdominal, and pelvic cavities by drawing straight lines between the shortest paths and the centers of the paths. The body cavities located between the superior thoracic aperture and the diaphragm, the diaphragm and the pelvic inlet, and the pelvic inlet and the pelvic outlet are regarded as the thoracic cavity, the abdominal cavity, and the pelvic cavity, respectively. The method was applied to 20 cases in which torso X-ray CT images were obtained. The results showed that the body cavities were extracted correctly in most cases: the thoracic cavity in 17 cases, the abdominal cavity in 19 cases, and the pelvic cavity in 18 cases. We confirmed that our proposed method is effective for recognizing these body cavities. As one of the applications of our study, segmentation of muscle, fat, and the rectum in CT images was performed using the information obtained for body cavity structures. The results

  14. Percutaneous Transhepatic Drainage of Inaccessible Abdominal Abscesses Following Abdominal Surgery Under Real-Time CT-Fluoroscopic Guidance

    This study evaluated the safety, feasibility, and clinical utility of transhepatic drainage of inaccessible abdominal abscesses retrospectively under real-time computed tomographic (CT) guidance. For abdominal abscesses, 12 consecutive patients received percutaneous transhepatic drainage. Abscesses were considered inaccessible using the usual access route because they were surrounded by the liver and other organs. The maximum diameters of abscesses were 4.6-9.5 cm (mean, 6.7 ± 1.4 cm). An 8-Fr catheter was advanced into the abscess cavity through the liver parenchyma using real-time CT fluoroscopic guidance. Safety, feasibility, procedure time, and clinical utility were evaluated. Drainage catheters were placed with no complications in abscess cavities through the liver parenchyma in all patients. The mean procedure time was 18.8 ± 9.2 min (range, 12-41 min). All abscesses were drained. They shrank immediately after catheter placement. In conclusions, this transhepatic approach under real-time CT fluoroscopic guidance is a safe, feasible, and useful technique for use of drainage of inaccessible abdominal abscesses.

  19. Updates on abdominal desmoid tumors

    2007-01-01

    Desmoid tumor is a monoclonal, fibroblastic proliferation arising in musculoaponeurotic structures. This connective tissue hyperplasia infiltrates locally, recurs frequentiy after resection but does not metastasize. Abdominal desmoid occurs sporadically, in association with some familial syndromes and often represents a clinical dilemma for surgeons. The enigmatic biology and anatomical location of abdominal desmoids make treatment recommendations difficult. This distinct pathological entity is reviewed with a specific focus on aetiology and management.

    2009-01-01

    Full Text Available Abstract Introduction Abdominal pregnancy is a rare event, but one that represents a grave risk to the health of the pregnant woman. An abdominal pregnancy is defined as an ectopic pregnancy that implants in the peritoneal cavity. Early abdominal pregnancy is self-limited by hemorrhage from trophoblastic invasion with complete abortion of the gestational sac that leaves a discrete crater. Advanced abdominal pregnancy is a rare event, with high fetal and maternal morbidity and mortality. Case presentation This is a case report of a 22-year-old primigravida with an abdominal pregnancy from a ruptured rudimentary horn. She was diagnosed as a case of term pregnancy with placenta previa with a transverse fetal lie and cervical fibroid and was prepared for an elective cesarean section. Intra-operatively, a live term female baby was extracted from the peritoneal cavity and it turned out to be an abdominal pregnancy from a ruptured rudimentary horn of a unicornuate uterus, which is a very rare condition. Mother and baby were in good condition after such a catastrophic event. Conclusion This case illustrates a rare obstetric condition which can be a severe catastrophic condition leading to maternal mortality and morbidity. It is imperative for every obstetrician to have in mind the possibility of abdominal pregnancy, although rare, especially in pregnant patients with persistent abdominal pain and painful fetal movements.

  4. Automatic segmentation of abdominal vessels for improved pancreas localization

    Farag, Amal; Liu, Jiamin; Summers, Ronald M.

    2014-03-01

    Accurate automatic detection and segmentation of abdominal organs from CT images is important for quantitative and qualitative organ tissue analysis as well as computer-aided diagnosis. The large variability of organ locations, the spatial interaction between organs that appear similar in medical scans and orientation and size variations are among the major challenges making the task very difficult. The pancreas poses these challenges in addition to its flexibility which allows for the shape of the tissue to vastly change. Due to the close proximity of the pancreas to numerous surrounding organs within the abdominal cavity the organ shifts according to the conditions of the organs within the abdomen, as such the pancreas is constantly changing. Combining these challenges with typically found patient-to-patient variations and scanning conditions the pancreas becomes harder to localize. In this paper we focus on three abdominal vessels that almost always abut the pancreas tissue and as such useful landmarks to identify the relative location of the pancreas. The splenic and portal veins extend from the hila of the spleen and liver, respectively, travel through the abdominal cavity and join at a position close to the head of the pancreas known as the portal confluence. A third vein, the superior mesenteric vein, anastomoses with the other two veins at the portal confluence. An automatic segmentation framework for obtaining the splenic vein, portal confluence and superior mesenteric vein is proposed using 17 contrast enhanced computed-tomography datasets. The proposed method uses outputs from the multi-organ multi-atlas label fusion and Frangi vesselness filter to obtain automatic seed points for vessel tracking and generation of statistical models of the desired vessels. The approach shows ability to identify the vessels and improve localization of the pancreas within the abdomen.

    2008-06-01

    Full Text Available Endometriosis is described as the presence of functioning endometrial tissue (glands and stroma outside the uterine cavity. The most common location is within the pelvis. However, extra pelvic endometriosis is a fairly uncommon disorder and difficult to diagnose. It can sometimes occur in a surgical scar. Scar endometriosis is a rare condition and difficult to diagnose. It mostly follows obstetrical and gynecological surgeries. It presents as a painful, slowly growing mass in or near a surgical scar. We report two cases of abdominal wall endometriosis following hysterotomy and cesarean section. Consequently the pathogenesis, diagnosis and treatment are discussed.

  8. Detection of abdominal bleeding in blunt abdominal trauma

    Arterial hemorrhage is the most serious immediate complication of blunt abdominal trauma. This paper discusses the detection and localization of active hemorrhage in nonpenetrating injury, as a modification of the technique using technetium-99m sulfur colloid to localize the site of active bleeding in the gastrointestinal tract. Any imaging protocol for suspected hepatosplenic injury can be easily modified to search for active intra-abdominal hemorrhage. The timely detection of unsuspected bleeding improves patient management by allowing the surgeon to reorder his or her treatment priorities. The early detection of clinically unsuspected intra-abdominal, retroperitoneal, or pelvic hemorrhage will identify those patients who may need more definitive diagnostic procedures, interventional angiography for control of bleeding, or surgical intervention. The 500,000-count view of the abdomen and pelvis can be easily incorporated into any existing trauma protocol using technetium-99m sulfur colloid, is of proven value, and adds little additional time to the study

    2003-01-01

    AIM: To evaluate the clinical, radiological and microbiological properties of abdominal tuberculosis (TB) and to discuss methods needed to get the diagnosis.METHODS: Thirty-one patients diagnosed as abdominal TB between March 1998 and December 2001 at the Gastroenterology Department of Kartal State Hospital,Istanbul, Turkey were evaluated prospectively. Complete physical examination, medical and family history, blood count erythrocyte sedimentation rate, routine biochemical tests,Mantoux skin test, chest X-ray and abdominal ultrasonography (USG) were performed in all cases, whereas microbiological examination of ascites, upper gastrointestinal endoscopy, colonoscopy or barium enema, abdominal tomography, mediastinoscopy, laparoscopy or laparotomy were done when needed.RESULTS: The median age of patients (14 females, 17males) was 34.2 years (range 15-65 years). The most frequent symptoms were abdominal pain and weight loss.Eleven patients had active pulmonary TB. The most common abdominal USG findings were ascites and hepatomegaly. Ascitic fluid analysis performed in 13 patients was found to be exudative and acid resistant bacilli were present in smear and cultured only in one patient with BacTec (3.2 %). Upper gastrointestinal endoscopy yielded nonspecific findings in 16 patients. Colonoscopy performed in 20 patients showed ulcers in 9 (45 %), nodules in 2 (10 %)and, stricture, polypoid lesions, granulomatous findings in terminal ileum and rectal fistula each in one patient (5 %).Laparoscopy on 4 patients showed dilated bowel loops,thickening in the mesentery, multiple ulcers and tubercles on the peritoneum. Patients with abdominal TB were divided into three groups according to the type of involvement.Fifteen patients (48 %) had intestinal TB, L1 patients (35.2 %) had tuberculous peritonitis and 5 (16.8 %)tuberculous lymphadenitis. The diagnosis of abdominal TB was confirmed microbiologically in 5 (16 %) and histopathologically in 19 patients (60.8 %). The

    1993-03-01

    A 26-years-old Indian male was admitted to hospital with loss of weight and vague abdominal pain of several weeks duration. Ultrasonography and computed tomography showed several expansive lesions near the pancreatic head, probably representing enlarged lymph nodes. A few milliliters of yellowish pus were aspirated by ultrasound guided aspiration. Microscopic examination of the pus showed trophozoits, and mycobacterium tuberculosis subsequently grew from the pus culture. Abdominal tuberculosis is a rare condition, particularly in the pancreas and the peripancreatic region. The report stresses the importance of considering the possible coexistance of more than one infectious disease in patients from endemic areas. 21 refs., 2 figs.

  13. Non-traumatic abdominal emergencies: imaging and intervention in sepsis

    Cross-sectional imaging, in particular CT, has become the main method of detecting abdominal collections. Indium-labelled white-cell scintigraphy and gallium scintigraphy are reserved for patients in whom there is a high clinical suspicion of abdominal sepsis but CT has not revealed a source of sepsis. Scintigraphy is also used in patients with suspected vascular graft infections or suspected infected hip prostheses. Percutaneous abscess drainage (PAD) has revolutionised the treatment of abdominal abscesses over the past 20 years, with repeat laparotomy for postoperative abscesses becoming a rare event. Ultrasound or CT can be used to guide PAD. Choosing an access route that does not cross intervening organs is of crucial importance to the safe performance of PAD. The Trocar or Seldinger techniques can be used with equal success. The cavity should be aspirated until dry and irrigated with saline. Repeat imaging after drainage is helpful to detect any undrained locules. PAD endpoints include patient defervescence, reduction in white blood cell count and catheter drainage of less than 10 ml per day. Details regarding PAD in specific abdominal regions are discussed. Success rates for PAD are high (close to 90%) in most abdominal organs. Slightly lower success rates are seen with PAD of pancreatic abscesses and abscesses associated with fistulas (60-85% success rates). Complication rates lie between 0% and 10%. Complications can be minimised by ensuring that the patient has broad spectrum antibiotic coverage before drainage, by carefully planning the access route and by ensuring diligent post-procedure care by radiology staff.

  15. Beam cavity interaction

    Gamp, A

    2011-01-01

    We begin by giving a description of the rf generator-cavity-beam coupled system in terms of basic quantities. Taking beam loading and cavity detuning into account, expressions for the cavity impedance as seen by the generator and as seen by the beam are derived. Subsequently methods of beam-loading compensation by cavity detuning, rf feedback, and feed-forward are described. Examples of digital rf phase and amplitude control for the special case of superconducting cavities are also given. Finally, a dedicated phase loop for damping synchrotron oscillations is discussed.

  16. Contemporary imaging in abdominal emergencies

    Imaging is often a fundamental part in the evaluation of an injured or ill child. A variety of imaging modalities (radiography, angiography/fluoroscopy, sonography, CT, magnetic resonance imaging and scintigraphy) are among the options. CT is worth focused attention because of its usefulness in a variety of emergency department settings, its increasing use, and its potential radiation risks. CT plays an important role in the evaluation of traumatic and nontraumatic abdominal emergencies in children. Therefore, the goal of this paper is to review current imaging approaches and controversies in the evaluation of common acute abdominal emergencies. Through discussion of various modalities, especially CT in evaluation of abdominal pain and trauma, the relative advantages and disadvantages including radiation risk will be reviewed. (orig.)

  20. Abdominal radiation causes bacterial translocation

    The purpose of this study was to determine if a single dose of radiation to the rat abdomen leads to bacterial translocation into the mesenteric lymph nodes (MLN). A second issue addressed was whether translocation correlates with anatomic damage to the mucosa. The radiated group (1100 cGy) which received anesthesia also was compared with a control group and a third group which received anesthesia alone but no abdominal radiation. Abdominal radiation lead to 100% positive cultures of MLN between 12 hr and 4 days postradiation. Bacterial translocation was almost nonexistent in the control and anesthesia group. Signs of inflammation and ulceration of the intestinal mucosa were not seen until Day 3 postradiation. Mucosal damage was maximal by Day 4. Bacterial translocation onto the MLN after a single dose of abdominal radiation was not apparently dependent on anatomical, histologic damage of the mucosa

  1. Radiological evaluation of abdominal trauma

    Simple abdomen film has played an important role in decision of emergency operations in patients with the abdominal trauma. Nowadays, it still acts as a primary and inevitable processes in emergency condition. At the Department of Radiology, Hanil Hospital, 70 patients, who were laparotomied due to penetrating or nonpernetraing abdominal trauma, were observed and analyzed with simple abdomen film after comparison with the operative findings. The results are as follows: 1. Most frequent age distribution was 10 to 39 years and marked 70%. Male was in 90% incidence. 2. Penetrating injury largely involved the small bowel and abdominal wall. Non-penetrating injury usually involved the spleen, small bowel, liver, kidney, pancreas, duodenum. 3. Single organ injury occurred in higher incidence at the small bowel and abdominal wall. Multiple organ injury occurred in higher incidence at the spleen, liver, kidney and pancreas. 4. Organ distribution was 26% in spleen, 22% in small bowel, 14% in liver, 11% in abdominal wall. 7% in pancreas, 7% in kidney. 5% in duodenum, 4% in GB and CBD, 2% in diaphragm, 2% in colon, and 1% in stomach. 5. The specific roentgen findings and their frequency which useful in differential diagnosis at abdominal trauma, were as follows: a) flank fluid; Detectable possibility was 71% in liver laceration, 69% in spleen laceration and 57% in pancreas laceration. b) ipsilateral psoas shadow obliteration; Detectable possibility was 57% in liver laceration, 57% in kidney laceration and 46% in spleen laceration. c) free air; Detactable possibility was 60% in duodenal perforation, and 36% in peroration of upper part of small bowel. d) Reflex ileus; Detectable possibility was 64% in small bowel, 50% in liver laceration and 35% in spleen laceration. e) rib fracture; Detactable possibility was 36% in liver laceration and 23% in spleen laceration. f) pleural effusion; Detectable possibility was 29% in liver laceration and 27% in spleen laceration

  2. Cavity turnover and equilibrium cavity densities in a cottonwood bottomland

    Sedgwick, James A.; Knopf, Fritz L.

    1992-01-01

    A fundamental factor regulating the numbers of secondary cavity nesting (SCN) birds is the number of extant cavities available for nesting. The number of available cavities may be thought of as being in an approximate equilibrium maintained by a very rough balance between recruitment and loss of cavities. Based on estimates of cavity recruitment and loss, we ascertained equilibrium cavity densities in a mature plains cottonwood (Populus sargentii) bottomland along the South Platte River in northeastern Colorado. Annual cavity recruitment, derived from density estimates of primary cavity nesting (PCN) birds and cavity excavation rates, was estimated to be 71-86 new cavities excavated/100 ha. Of 180 active cavities of 11 species of cavity-nesting birds found in 1985 and 1986, 83 were no longer usable by 1990, giving an average instantaneous rate of cavity loss of r = -0.230. From these values of cavity recruitment and cavity loss, equilibrium cavity density along the South Platte is 238-289 cavities/100 ha. This range of equilibrium cavity density is only slightly above the minimum of 205 cavities/100 ha required by SCN's and suggests that cavity availability may be limiting SCN densities along the South Platte River. We submit that snag management alone does not adequately address SCN habitat needs, and that cavity management, expressed in terms of cavity turnover and cavity densities, may be more useful.

    2007-01-01

    Although the case fatality rate for ectopic pregnancies has decreased to 0.08% in industrialized countries, it still represents 3.8% of maternal mortality in the United States alone. In developing countries, the case fatality rate varies from 3% to 27%. Laparoscopic management of tubal pregnancies is now the standard form of treatment where this technology is available. Abdominal pregnancies are rare, and secondary implantation of tubal ectopic pregnancies is the most common cause of abdominal gestations. We present an interesting case of secondary implantation of a tubal ectopic pregnancy to highlight the appendix as a possible secondary implantation site after a tubal ectopic pregnancy.

    2002-09-01

    Eighty five children with recurrent abdominal pain(RAP) were studied. Organic cause was noticed in 70 cases and non-organic in 15 cases. Giardiasis was the commonest organic cause in 57 (67.0 percent), either alone or with other parasitic infestations. Other organic causes include gallstones (4.7 percent), urinary infections (4.7 percent), esophagitis/gastritis (3.5 percent) and abdominal tuberculosis (2.3 percent). Single parent, school phobia, sibling rivalry, RAP in other family members and nocturnal enuresis are significant factors associated with nonorganic causes PMID:12368527

  5. Plain abdominal film and abdominal ultrasound in intestine occlusion

    Plain film of the abdomen is widely used in the diagnostic evaluation of intestinal occlusion. Even though this technique can yield a panoramic and high-resolution view of gas-filled intestinal loops, several factors, such as type and duration of occlusion, neurovascular status of the intestine and general patient condition, may reduce the diagnostic specificy of the plain film relative to the organic or functional nature of the occlusion. From 1987 to 1989, fifty-four patients with intestinal occlusion were studied combining plain abdominal film with abdominal ultrasound (US). This was done in order to evaluate whether the additional information obtained from US could be of value in better determining the nature of the ileus. US evaluation was guided by the information already obtained from plain film which better demonstrates gas-filled loops. The results show that in all 27 cases of dynamic ileus (intestinal ischemia, acute appendicitis, acute cholecistis, acute pancreatitis or blunt abdominal trauma) US demonstrates: intestinal loops slightly increased in caliber, with liquid content, or loops containing rare hyperechoic particles, intestinal wall thickening and no peristalsis. In 27 cases of acute, chronic or complicated mechanical ileus (adhesions, internal hernia, intestinal neoplasm, peritoneal seedings) US shows: 1) in acute occlusion: hyperperistaltic intestinal loops containing inhomogeneous liquid; 2) in chronic occlusion: liquid content with a solid echigenic component; 3) in complicated occlusion: liquid stasis, frequent increase in wall thickness, moderate peritoneal effusion and inefficient peristalsis. In conclusion, based on the obtained data, the authors feel that the combination of plain abdominal film and abdominal US can be useful in the work-up of patient with intestinal occlusion. The information provided by US allows a better definition of the nature of the ileus

  6. Pulsatile blood flow in Abdominal Aortic Aneurysms

    Salsac, Anne-Virginie; Lasheras, Juan C.; Singel, Soeren; Varga, Chris

    2001-11-01

    We discuss the results of combined in-vitro laboratory measurements and clinical observations aimed at determining the effect that the unsteady wall shear stresses and the pressure may have on the growth and eventual rupturing of an Abdominal Aortic Aneurysm (AAA), a permanent bulging-like dilatation occurring near the aortic bifurcation. In recent years, new non-invasive techniques, such as stenting, have been used to treat these AAAs. However, the development of these implants, aimed at stopping the growth of the aneurysm, has been hampered by the lack of understanding of the effect that the hemodynamic forces have on the growth mechanism. Since current in-vivo measuring techniques lack the precision and the necessary resolution, we have performed measurements of the pressure and shear stresses in laboratory models. The models of the AAA were obtained from high resolution three-dimensional CAT/SCANS performed in patients at early stages of the disease. Preliminary DPIV measurements show that the pulsatile blood flow discharging into the cavity of the aneurysm leads to large spikes of pressure and wall shear stresses near and around its distal end, indicating a possible correlation between the regions of high wall shear stresses and the observed location of the growth of the aneurysm.

    Unaltered fat is a permanent component of the abdominal cavity, even in slim individuals. Visceral adiposity is one of the important factors contributing to diabetes, cardiovascular diseases and certain neoplasms. Moreover, the adipose tissue is an important endocrine and immune organ of complex function both when normal and pathological. Its role in plastic surgery, reconstruction and transplantology is a separate issue. The adipose tissue has recently drawn the attention of research institutes owing to being a rich source of stem cells. This review, however, does not include these issues. The identification of fat is relatively easy using computed tomography and magnetic resonance imaging. It can be more difficult in an ultrasound examination for several reasons. The aim of this paper is to present various problems associated with US imaging of unaltered intra-abdominal fat located beyond organs. Based on the literature and experience, it has been demonstrated that the adipose tissue in the abdominal cavity has variable echogenicity, which primarily depends on the amount of extracellular fluid and the number of connective tissue septa, i.e. elements that potentiate the number of areas that reflect and scatter ultrasonic waves. The normal adipose tissue presents itself on a broad gray scale: from a hyperechoic area, through numerous structures of lower reflection intensity, to nearly anechoic regions mimicking the presence of pathological fluid collections. The features that facilitate proper identification of this tissue are: sharp margins, homogeneous structure, high compressibility under transducer pressure, no signs of infiltration of the surrounding structures and no signs of vascularization when examined with the color and power Doppler. The accumulation of fat tissue in the abdominal cavity can be generalized, regional or focal. The identification of the adipose tissue in the abdominal cavity using ultrasonography is not always easy. When in doubt, the

  8. Ultrasonic and X-ray computer tomographic examinations in the diagnosis of pyoinflammatory diseases of the abdominal and retroperitoneal organs

  11. Dehydration related abdominal pain (drap)

    Objective: To describe the frequency of dehydration as a medical cause of acute abdomen. Subjects and Methods: All the patients reporting with abdominal pain to the surgical outpatient department or the emergency department were reviewed in the study. The clinical findings in all these cases were studied along with the mode of their management and outcome. Results: Of all the patients presenting with abdominal pain, 3.3% (n=68) were suffering from dehydration related abdominal pain. They were predominantly males in a ratio of 8.7: 1, mostly in the 2nd and 3rd decades of their lives. All these cases were suffering from acute or chronic dehydration were provisionally diagnosed by general practitioners as 'acute abdomen' and referred for surgical consultation. Associated symptoms included vomiting in 42.6%, backache in 91.2%, headache in 95.6%, and pain in lower limbs in 97.1 % of the cases. 83.8% required indoor management with intravenous fluids. All the patients became asymptomatic with rehydration therapy. Conclusion: Dehydration is a possible cause of severe abdominal pain. There is a need to educate the general public about the benefits of adequate fluid intake. (author)

    Kashikhin, V.; Borissov, E.; Foster, G.W.; Makulski, A.; Pischalnikov, Y.; Khabiboulline, T.; /Fermilab

    2009-05-01

    A novel prototype of SCRF cavity tuner is being designed and tested at Fermilab. This is a superconducting C-type iron dominated magnet having a 10 mm gap, axial symmetry, and a 1 Tesla field. Inside the gap is mounted a superconducting coil capable of moving {+-} 1 mm and producing a longitudinal force up to {+-} 1.5 kN. The static force applied to the RF cavity flanges provides a long-term cavity geometry tuning to a nominal frequency. The same coil powered by fast AC current pulse delivers mechanical perturbation for fast cavity tuning. This fast mechanical perturbation could be used to compensate a dynamic RF cavity detuning caused by cavity Lorentz forces and microphonics. A special configuration of magnet system was designed and tested.

  17. Superconducting cavity development

    Design and development work of the superconducting cavities for the Neutron Science Project is being continued since 1995. In the cavity design work, RF and structural analyses were carried out in order to determine the cavity shape and to obtain the RF and structural parameters. In the cavity development work, preparation of the test facility, fabrication and tests of the two single-cell prototype cavities of β=0.5 were performed. Good performance of the cavity was demonstrated in the test; obtained surface peak electric field of 44 MV/m is much higher than the design value of 16 MV/m. Resonant frequency shifts due to the vacuum load and the Lorentz force were also measured in the test. (author)

  7. Intestinal contrasting in abdominal CT

    In 56 patients undergoing abdominal CT the gastro-intestinal tract was defined by negative contrast instead of the conventional positive contrast from an iodine containing contrast medium. The contrast material was a 2 1/2% mannitol solution and was used for filling the rectum. Filling of the gastro-intestinal tract was of similar quality to that obtained with positve contrast media. The number of artifacts due to high contrast boundaries was slightly greater with the negative contrast than if would have been with positive contrast. Differentiation of the gastro-intestinal tract from other abdominal organs was equally good for both methods. The negative contrast method was poor in diagnosing cystic tumours but proved much better than positive contrast for evaluating the wall of the gastro-intestinal tract. (orig.)

  8. Sonography of blunt abdominal trauma

    Sonographic examination of the abdomen after blunt abdominal trauma represents a rapid and effective diagnostic method without bothering the patient. It has proved its value not only in the confirmation or exclusion of free fluid in the abdomen caused by liver of spleen rupture, but also in such cases actually it replaces peritoneal lavage or exploratory laparotomy. It is also qualified for diagnosis of intraparenchymal or subcapsular hemorrhages, intraperitoneal as well as retroperitoneal and for follow up. In particualr delayed bleedings including the risk of a retarded organ rupture can be detected early. A failure rate of 1.4% in 282 sonographically examined cases of blunt abdominal trauma further confirms the reliability of this method. (orig.)

    @@ Case History Mr. Li, a university student aged 23 years, paid his first visit on July 16, 2001, with the chief complaint of abdominal pain for one day. The patient stated that one day before when it happened to be the weekend, he got abdominal pain after supper, which went worse gradually and caused him to roll all over in bed. The pain was slightly alleviated half an hour later after he had taken some pain killers. Upon inquiry, the patient said that because of their newly graduation from the university, he and his classmates were so excited that they went to have a sumptuous lunch with alcoholic drinks. And in the evening he ate again a delicious supper cooked for him by his mother, after which he continued to have some fruit and dessert.

  11. CT of abdominal blunt trauma

    We studied CT findings and interventional radiology including therapeutic procedures in 43 cases with abdominal blunt trauma, retrospectively. All of parenchymal organ's injuries, and injuries of duodenum and retroperitoneum were correctly diagnosed by CT. In 14 cases with only hemoperitoneum or no positive findings on CT, 4 cases were jejunal perforations, and remaining 10 cases were conservatively treated and relieved. We have to take care that the similar CT findings include the opposite results to need surgery and not. (author)

  12. [A case of abdominal wall actinomycosis].

    Kim, Kyung Hoon; Lee, Jin Soo; Cho, Hyeong Jun; Choi, Seung Bong; Cheung, Dae Young; Kim, Jin Il; Lee, In Kyu

    2015-04-01

    Actinomycosis is a chronic suppurative granulomatous infectious disease caused by actinomyces species that is characterized by formation of characteristic clumps called as sulfur granules. Abdominal actinomycosis is a rare disease and is often difficult to diagnose before operation. Abdominal actinomycosis infiltrating into the abdominal wall and adhering to the colon is even rarer. Most abdominal actinomycosis develops after operation, trauma or inflammatory bowel disease, and is also considered as an opportunistic infection in immunocompromised patient with underlying malignancy, diabetes mellitus, human immunodeficiency virus infection, etc. Actinomycosis is diagnosed based on histologic demonstration of sulfur granules in surgically resected specimen or pus, and treatment consists of long-term penicillin based antibiotics therapy with or without surgical resection. Herein, we report an unusual case of abdominal wall actinomycosis which developed in a patient after acupuncture and presented as abdominal wall mass that was first mistaken for abdominal wall invasion of diverticulum perforation.

    Myneni, Ganapati Rao; Hjorvarsson, Bjorgvin; Ciovati, Gianluigi

    2006-12-19

    A niobium cavity exhibiting high quality factors at high gradients is provided by treating a niobium cavity through a process comprising: 1) removing surface oxides by plasma etching or a similar process; 2) removing hydrogen or other gases absorbed in the bulk niobium by high temperature treatment of the cavity under ultra high vacuum to achieve hydrogen outgassing; and 3) assuring the long term chemical stability of the niobium cavity by applying a passivating layer of a superconducting material having a superconducting transition temperature higher than niobium thereby reducing losses from electron (cooper pair) scattering in the near surface region of the interior of the niobium cavity. According to a preferred embodiment, the passivating layer comprises niobium nitride (NbN) applied by reactive sputtering.

  14. Abdominal wound closure: current perspectives

    Williams ZF

    2015-12-01

    Full Text Available Zachary F Williams, William W Hope Department of Surgery, South East Area Health Education Center, New Hanover Regional Medical Center, Wilmington, NC, USA Abstract: This review examines both early and late wound complications following laparotomy closure, with particular emphasis on technical aspects that reduce hernia formation. Abdominal fascial closure is an area of considerable variation within the field of general surgery. The formation of hernias following abdominal wall incisions continues to be a challenging problem. Ventral hernia repairs are among the most common surgeries performed by general surgeons, and despite many technical advances in the field, incisional hernia rates remain high. Much attention and research has been directed to the surgical management of hernias. Less focus has been placed on prevention of hernia formation despite its obvious importance. This review examines the effects of factors such as the type of incision, suture type and size, closure method, patient risk factors, and the use of prophylactic mesh. Keywords: incisional, abdominal, hernia, prevention, wound closure techniques 

  15. Acute Abdominal Pain in Children.

    Reust, Carin E; Williams, Amy

    2016-05-15

    Acute abdominal pain accounts for approximately 9% of childhood primary care office visits. Symptoms and signs that increase the likelihood of a surgical cause for pain include fever, bilious vomiting, bloody diarrhea, absent bowel sounds, voluntary guarding, rigidity, and rebound tenderness. The age of the child can help focus the differential diagnosis. In infants and toddlers, clinicians should consider congenital anomalies and other causes, including malrotation, hernias, Meckel diverticulum, or intussusception. In school-aged children, constipation and infectious causes of pain, such as gastroenteritis, colitis, respiratory infections, and urinary tract infections, are more common. In female adolescents, clinicians should consider pelvic inflammatory disease, pregnancy, ruptured ovarian cysts, or ovarian torsion. Initial laboratory tests include complete blood count, erythrocyte sedimentation rate or C-reactive protein, urinalysis, and a pregnancy test. Abdominal radiography can be used to diagnose constipation or obstruction. Ultrasonography is the initial choice in children for the diagnosis of cholecystitis, pancreatitis, ovarian cyst, ovarian or testicular torsion, pelvic inflammatory disease, pregnancy-related pathology, and appendicitis. Appendicitis is the most common cause of acute abdominal pain requiring surgery, with a peak incidence during adolescence. When the appendix is not clearly visible on ultrasonography, computed tomography or magnetic resonance imaging can be used to confirm the diagnosis. PMID:27175718

  17. Apparatus for treating the walls and floor of the pelvic cavity with radiation

    An apparatus for reaing carcinoma of the walls and floor of the pelvic cavity is described. An elongated tube has an inner end adapted to be placed in the pelvic cavity and an outer end adapted to extend through to the outside of the body. Radioactive material is placed at the inner end. An inner balloon above the radioactive material is inflated to hold a body of liquid shielding material such as mercury. A lower balloon portion beneath the inner balloon spaces areas to be treated such as the walls and floor of the pelvic cavity from the radioactive material. An upper balloon portion above the inner balloon keeps the intestines out of the pelvic cavity and away from the radioactive material. The apparatus is inserted into the pelvic cavity through an abdominal incision. When treating a woman for carcinoma in the walls and floor of the pelvic cavity the tube is moved through the vaginal passage from the inside outwardly. When treating a woman with a closed vaginal passage, as may result from surgery, or when treating a man, such as for carcinoma of the bladder, the tube will pass out of the body through a lower abdominal incision. Following treatment, all balloons are deflated so that the apparatus can be withdrawn through the vaginal passage or the lower abdominal incision, as the case may be. (auth)

    Shima, S.; Sugiura, Y.; Yonekawa, H.; Ogata, T. (National Defence Medical Coll., Tokorosawa, Saitama (Japan))

    1982-03-01

    In order to evaluate the sensitivity of computed tomography (CT) scan in detecting the abdominal lymph node metastases, preoperative CT scan was performed in 16 patients with carcinoma of the esophagus and gastric cardia. Ten patients (62.5%) had pathological evidence of lymph node metastases in the abdominal cavity and 4 of them were identified to involve the para-aortic nodes. CT scan correctly demonstrated the lymph node metastases in the para-aortic and celiac axisis areas, but failed to detect other abdominal lymph node involvements, which were small enough to be excised by operation. The para-aortic nodes on the CT scan showed the following two features; one was nodular mass in shape, which did not obscure the aorta or inferior vena cava, and the other was conglomerated mass, which was difficult to be distinguished from the aorta. The former was resectable and the latter was not.

  20. Panniculitis of the abdominal wall: Diagnosis by In-111-WBC and radiogallium

    Radioindium imaging (In-111-oxine-white blood cells), performed in a massively obese male, revealed a pattern of activity that was thought to represent a ptotic colon. The patient was restudied with Ga-67 citrate and a similar anterior pattern of activity was noted. On the lateral view of the abdomen, markers established that the activity was external to the abdominal cavity. This corresponded to an active panniculitis which was successfully drained. (orig.)

  3. SPS RF Accelerating Cavity

    1979-01-01

    This picture shows one of the 2 new cavities installed in 1978-1979. The main RF-system of the SPS comprises four cavities: two of 20 m length and two of 16.5 m length. They are all installed in one long straight section (LSS 3). These cavities are of the travelling-wave type operating at a centre frequency of 200.2 MHz. They are wideband, filling time about 700 ns and untuned. The power amplifiers, using tetrodes are installed in a surface building 200 m from the cavities. Initially only two cavities were installed, a third cavity was installed in 1978 and a forth one in 1979. The number of power amplifiers was also increased: to the first 2 MW plant a second 2 MW plant was added and by end 1979 there were 8 500 kW units combined in pairs to feed each of the 4 cavities with up to about 1 MW RF power, resulting in a total accelerating voltage of about 8 MV.

  5. Hydroforming of elliptical cavities

    Singer, W.; Singer, X.; Jelezov, I.; Kneisel, P.

    2015-02-01

    Activities of the past several years in developing the technique of forming seamless (weldless) cavity cells by hydroforming are summarized. An overview of the technique developed at DESY for the fabrication of single cells and multicells of the TESLA cavity shape is given and the major rf results are presented. The forming is performed by expanding a seamless tube with internal water pressure while simultaneously swaging it axially. Prior to the expansion the tube is necked at the iris area and at the ends. Tube radii and axial displacements are computer controlled during the forming process in accordance with results of finite element method simulations for necking and expansion using the experimentally obtained strain-stress relationship of tube material. In cooperation with industry different methods of niobium seamless tube production have been explored. The most appropriate and successful method is a combination of spinning or deep drawing with flow forming. Several single-cell niobium cavities of the 1.3 GHz TESLA shape were produced by hydroforming. They reached accelerating gradients Eacc up to 35 MV /m after buffered chemical polishing (BCP) and up to 42 MV /m after electropolishing (EP). More recent work concentrated on fabrication and testing of multicell and nine-cell cavities. Several seamless two- and three-cell units were explored. Accelerating gradients Eacc of 30 - 35 MV /m were measured after BCP and Eacc up to 40 MV /m were reached after EP. Nine-cell niobium cavities combining three three-cell units were completed at the company E. Zanon. These cavities reached accelerating gradients of Eacc=30 - 35 MV /m . One cavity is successfully integrated in an XFEL cryomodule and is used in the operation of the FLASH linear accelerator at DESY. Additionally the fabrication of bimetallic single-cell and multicell NbCu cavities by hydroforming was successfully developed. Several NbCu clad single-cell and double-cell cavities of the TESLA shape have been

    The main RF-system of the SPS comprises four cavities: two of 20 m length and two of 16.5 m length. They are all installed in one long straight section (LSS 3). These cavities are of the travelling-wave type operating at a centre frequency of 200.2 MHz. They are wideband, filling time about 700 ns and untuned. A power of up to 790 kW can be supplied to each giving a total accelerating voltage of about 8 MV. The power amplifiers, using tetrodes are installed in a surface building 200 m from the cavities.

    Full Text Available Extrauterine abdominal pregnancy is extremely rare and is frequently missed during antenatal care, despite the routine use of obstetrics ultrasound. A 23 year old primigravida at 39 weeks of gestation was admitted to the department on December 2 , 2012, in routine hour with transverse lie with oligohydramnios. On examination her vitals and laboratory investigation were within normal limits . One of the ultrasonographic scanning done by radiologist at 35 wk. 3 days gestation demonstrated a single live intrauterine fetus of CGA 33 wk. 1 day with transverse lie , fundal gr II placenta and AFI - 10 cm. Ultrasonography done at the department on the day of admission demonstrated single live intrauterine fetus with transverse lie and AFI - 3.8 cm and EFW 2.4 Kg and placenta was right anterior.. She was planned for elective caesarean section on account of transverse lie and oligohydramnios at term. At laparotomy the following findings were made: Secondary abdominal pregnancy arising from right tubal ectopic rupture and making pseudogesta tional sac with meconium stained liquor. Omentum , right tube and ovary were adhered to sac. The uterus and left tube and ovary were healthy and normal . Other abdominal organs were normal. A 1.5 Kg live male baby with good Apgar score and incompletely formed mandible extracted from pseudo gestational sac. There was significant bleeding from pseudogestational sac and patient went in shock during intraoperative period. One unit whole blood transfused during intraoperative period. Placenta was adherent to the pseudogestational sac so Psudogestational sac was removed with placenta in situ and right sided salpingo - o ophrectomy was also done due to their adherence. Hemostasis was secured. The patient and baby progressed well and were discharged on the seventh postoperative day

  11. accelerating cavity from LEP

    This is an accelerating cavity from LEP, with a layer of niobium on the inside. Operating at 4.2 degrees above absolute zero, the niobium is superconducting and carries an accelerating field of 6 million volts per metre with negligible losses. Each cavity has a surface of 6 m2. The niobium layer is only 1.2 microns thick, ten times thinner than a hair. Such a large area had never been coated to such a high accuracy. A speck of dust could ruin the performance of the whole cavity so the work had to be done in an extremely clean environment. These challenging requirements pushed European industry to new achievements. 256 of these cavities are now used in LEP to double the energy of the particle beams.

  12. Moving Detectors in Cavities

    Obadia, N

    2007-01-01

    We consider two-level detectors, coupled to a quantum scalar field, moving inside cavities. We highlight some pathological resonant effects due to abrupt boundaries, and decide to describe the cavity by switching smoothly the interaction by a time-dependent gate-like function. Considering uniformly accelerated trajectories, we show that some specific choices of non-adiabatic switching have led to hazardous interpretations about the enhancement of the Unruh effect in cavities. More specifically, we show that the emission/absorption ratio takes arbitrary high values according to the emitted quanta properties and to the transients undergone at the entrance and the exit of the cavity, {\\it independently of the acceleration}. An explicit example is provided where we show that inertial and uniformly accelerated world-lines can even lead to the same ``pseudo-temperature''.

  13. SPS accelerating cavity

    1976-01-01

    The SPS started up with 2 accelerating cavities (each consisting of 5 tank sections) in LSS3. They have a 200 MHz travelling wave structure (see 7411032 and 7802190) and 750 kW of power is fed to each of the cavities from a 1 MW tetrode power amplifier, located in a surface building above, via a coaxial transmission line. Clemens Zettler, builder of the SPS RF system, is standing at the side of one of the cavities. In 1978 and 1979 another 2 cavities were added and entered service in 1980. These were part of the intensity improvement programme and served well for the new role of the SPS as proton-antiproton collider. See also 7411032, 8011289, 8104138, 8302397.

  14. Screening for Abdominal Aortic Aneurysm

    2014-01-01

    Abdominal Aortic Aneurysm (AAA) is a common disease with a prevalence of 1.5-2.0% in 65-year old men in Sweden. The risk of having AAA is increased with smoking, high age, family history of AAA and cardiovascular disease. Women have a lower prevalence (0.5%) and develop AAA later in life. An AAA seldom gives any symptom prior to rupture. Untreated rupture is associated with 100% mortality, while surgically treated rupture is associated with 25-70% mortality. Prophylactic sur...

  15. Abdominal manifestations of autoimmune disorders

    Full text: Immunoglobulin G4-related disease was recognized as a systemic disease since various extrapancreatic lesions were observed in patients with autoimmune pancreatitis (AIP). The real etiology and pathogenesis of IgG4-RD is still not clearly understood. Moreover the exact role of IgG4 or IgG4-positive plasma cells in this disease has not yet been elucidated. only some inconsistent biological features such as hypergammaglobulinemia or hypocomplementemia support the autoimmune nature of the disease process. various names have been ascribed to this clinicopathological entity including IgG4-related sclerosing disease, IgG4-related systemic sclerosing disease, IgG4-related disease, IgG4-related autoimmune disease, hyper-IgG4 disease and IgG4-related systemic disease. The extrapancreatic lesions of IgG4-RD also exhibit the same characteristic histologic features including dense lymphoplasmacytic infiltrate, massive storiform fibrosis, and obliterative phlebitis as seen in IgG4-related pancreatitis. Abdominal manifestations include the following organs/systems: Bile ducts: Sclerosing cholangitis; Gallbladder and liver: Acalculous sclerosis cholecytitis with diffuse wall thickening; hepatic inflammatory pseudotumorts; Kidneys: round or wedge-shaped renal cortical nodules, peripheral cortical; lesions, mass like lesions or renal pelvic involvement; Prostate, urethra, seminal vesicle, vas deferens, uterine cervix; Autoimmune prostatitis; Retroperitoneum: Retroperitoneal fibrosis. thin or mildly thick homogeneous soft tissue lesion surrounding the abdominal aorta and its branches but also bulky masses causing hydronephroureterosis; Mesentery: Sclerosing mesenteritis usually involving the root of the mesentery; Bowel: Inflammatory bowel diseases mimicking Crohn’s disease or ulcerative colitis. various types of sclerosing nodular lesions of the bowel wall; Stomach: Gastritis, gastric ulcers and focal masses mimicking submucosal tumor; omentum: Infiltration mimicking

    Although leprosy involves the oral cavity in up to 60% of the patients, examination of the oral cavity in leprosy clinics or oral health science clinics is often neglected. Oral involvement in leprosy can broadly be divided into non-specific and specific lesions. In this review, we discuss various oral manifestations in leprosy patients so as to increase the awareness about this aspect among dermatologists and dental surgeons.

    2009-01-01

    Abstract: During insufflation of the abdomen to create a pneumoperitoneum for laparoscopy, both intra abdominal pressure and insufflated volume can be measured and are used to calculate the abdominal pressure-volume relationship. First, an accurate, linear relationship was identified using a mathematical model with an elastance, E, or its reciprocal the compliance C and with a pressure at zero volume, PV0. This function was stable and could be used to describe the abdominal characteristics of...

    Full Text Available Beatrice Scicchitano,1 Gareth Humphreys,1 Sally G Mitton,2 Thiagarajan Jaiganesh1 1Children's Emergency Department, 2Department of Paediatric Gastroenterology, St Georges Hospital, St Georges Healthcare NHS Trust, Tooting, London, United Kingdom Abstract: The childhood condition of abdominal migraine has been described under many different synonyms, including "abdominal epilepsy", "recurrent abdominal pain", "cyclical vomiting syndrome", and "functional gastrointestinal disorder". In the early literature, abdominal migraine is included in the "childhood periodic syndrome", first described by Wyllie and Schlesinger in 1933. Abdominal migraine has emerged over the last century as a diagnostic entity in its own right thanks to the development of well defined diagnostic criteria and its recent inclusion in the International Headache Society's Classification of Headache disorders. Despite this progress, little is known about the pathophysiology of the condition, and the treatment options are poorly defined. Here we summarize the recent literature, with particular focus on establishing the diagnosis of abdominal migraine and its pathophysiology, and suggest an approach to management.

  4. Abdominal Wall Abscess due to Acute Perforated Sigmoid Diverticulitis: A Case Report with MDCT and US Findings

    Rafailidis Vasileios

    2013-01-01

    Full Text Available Perforation of the inflamed diverticula is a common diverticulitis complication. It usually leads to the formation of a local abscess. In some rare cases, the inflammatory process may spread towards extra-abdominal sites like the anterior or posterior abdominal wall or the thigh and form an abscess in these sites. We present the case of a 73-year-old man with a history of pain at the lower left quadrant of the abdomen for 20 days and a visible mass in this site. Ultrasonography and computed tomography revealed this mass to be an abscess of the abdominal wall which had been formed by the spread of ruptured sigmoid diverticulitis by continuity of tissue through the lower left abdominal wall. Local drainage of the abscess was performed and the patient was discharged after alleviation of symptoms and an uneventful course. We also discuss causes of abdominal wall abscesses along with the possible pathways by which an intra-abdominal abscess could spread outside the abdominal cavity.

  5. Abdominal ultrasound in AIDS patients

    To analyze the ultrasonography findings in abdomen in the AIDS patients in our hospital, as well as the indications for this exploration, assessing the role of abdominal ultrasound (AU). The ultrasonographic and clinical findings in 527 patients who underwent a total of 715 explorations between 1992 and 1996 were studied. Hepatomegaly and/or splenomegaly, usually homogeneous, were observed in nearly half of the studies (45%); one third of the patients with marked splenomegaly presented visceral leishmaniasis. Focal lesions in liver and/or spleen, corresponding to angiomas, abscesses, lymphomatous lesions and metastasis, were detected in 5.7% of the explorations. Thirty-five percent of the AU revealed the presence of lymphadenopathy; nodes measuring over 2.5 cm were usually related to potential treatable infection or neoplasm. Thickening of the gallbladder wall did not usually indicate the presence of acute cholecystitis unless Murphy''s sign was also detected. Bile duct dilation and wall thickening was related to opportunistic cholangitis, and the increase in the echogenicity of the renal parenchyma was linked to AIDS-related nephropathy. Despite the fact that many of findings with AU are nonspecific, we consider that this approach should be the principal diagnostic technique in AIDS patients with suspected abdominal pathology or fever of unknown origin.

  6. Percutaneous drainage of abdominal abcess

    Men, Sueleyman E-mail: suleyman.men@deu.edu.tr; Akhan, Okan; Koeroglu, Mert

    2002-09-01

    The mortality in undrained abdominal abscesses is high with a mortality rate ranging between 45 and 100%. The outcome in abdominal abscesses, however, has improved due to advances in image guided percutaneous interventional techniques. The main indications for the catheter drainage include treatment or palliation of sepsis associated with an infected fluid collection, and alleviation of the symptoms that may be caused by fluid collections by virtue of their size, like pancreatic pseudocele or lymphocele. The single liver abscesses may be drained with ultrasound guidance only, whereas the multiple abscesses usually require computed tomography (CT) guidance and placement of multiple catheters. The pancreatic abscesses are generally drained routinely and urgently. Non-infected pancreatic pseudocysts may be simply observed unless they are symptomatic or cause problems such as pain or obstruction of the biliary or the gastrointestinal tract. Percutaneous routes that have been described to drain pelvic abscesses include transrectal or transvaginal approach with sonographic guidance, a transgluteal, paracoccygeal-infragluteal, or perineal approach through the greater sciatic foramen with CT guidance. Both the renal and the perirenal abscesses are amenable to percutaneous drainage. Percutaneous drainage provides an effective and safe alternative to more invasive surgical drainage in most patients with psoas abscesses as well.

  7. Major abdominal evisceration injuries in dogs and cats: 12 cases (1998-2008).

    Gower, Sara B; Weisse, Chick W; Brown, Dorothy C

    2009-06-15

    OBJECTIVE- To describe the clinical characteristics, treatment, complications, and outcome of dogs and cats treated surgically for major abdominal evisceration. DESIGN- Retrospective case series. ANIMALS- 8 dogs and 4 cats. PROCEDURES- Medical records from January 1998 through March 2008 were reviewed to identify animals that underwent surgery for major abdominal evisceration. Data regarding cause of evisceration, signalment, physiologic variables, and hematologic variables were collected. Details of treatment, duration of hospitalization, and outcome were recorded. Linear regression analysis was performed to evaluate the association of signalment, physiologic variables, and hematologic variables on the number of days of hospitalization. RESULTS- Major abdominal evisceration was secondary to a traumatic event in 4 animals and to postsurgical dehiscence in 8 animals. All animals had evisceration of the intestines and gross contamination with dirt, leaves, or litter. Two animals eviscerated the spleen, and 1 animal had a perforated colon and was leaking feces into the peritoneal cavity. All animals underwent exploratory abdominal surgery. Surgical procedures performed included resection of compromised intestine, body wall repair, diaphragmatic hernia repair, nephrectomy, splenectomy, and primary colonic repair. All animals survived to discharge from the hospital. Median duration of hospitalization was 4 days (range, 1 to 7 days). Factors associated with an increase in duration of hospitalization included evisceration secondary to trauma, high lactate concentration at time of admission, and small body size. CONCLUSIONS AND CLINICAL RELEVANCE- Despite the dramatic appearance of major abdominal evisceration in cats and dogs, prompt and aggressive medical and surgical intervention can provide a favorable outcome.

  8. EVENTRATION OF LEFT HEMIDIAPHRAGM MIMICKING AS CAVITY

    Kansal

    2015-10-01

    Full Text Available Eventration of diaphragm is a condition in which there is abnormal elevation of the diaphragm as a result of thinning of muscular layer. It can be congenital as well as acquired. It is more common left sided. Herniation of the abdominal contents can be there. Clinical manifestations range from asymptomatic to life threatening respiratory distress requiring mechanical ventilator support. Ultrasound provides valuable information regarding the integrity of the diaphragm. Other imaging modalities include fluoroscopy, CT and MRI that provide valuable information when diagnosis is in doubt. We are presenting a case report of 25-year-old male with eventration of left hemidiaphragm mimicking as cavity. After taking detail history, examination and proper investigations we finally reached to this diagnosis.

  9. Abdominal Manifestations of Lymphoma: Spectrum of Imaging Features

    Non-Hodgkin and Hodgkin lymphomas frequently involve many structures in the abdomen and pelvis. Extranodal disease is more common with Non-Hodgkin's lymphoma than with Hodgkin's lymphoma. Though it may be part of a systemic lymphoma, single onset of nodal lymphoma is not rare. Extranodal lymphoma has been described in virtually every organ and tissue. In decreasing order of frequency, the spleen, liver, gastrointestinal tract, pancreas, abdominal wall, genitourinary tract, adrenal, peritoneal cavity, and biliary tract are involved. The purpose of this review is to discuss and illustrate the spectrum of appearances of nodal and extranodal lymphomas, including AIDS-related lymphomas, in the abdominopelvic region using a multimodality approach, especially cross-sectional imaging techniques. The most common radiologic patterns of involvement are illustrated. Familiarity with the imaging manifestations that are diagnostically specific for lymphoma is important because imaging plays an important role in the noninvasive management of disease

  10. Diagnostic application of labelled leukocytes in gastroenterology and abdominal surgery

    A total of 18 patients suspected of inflammatory process or abcessus in the abdominal cavity have been studied by scintiscanning with autologous leukocytes labelled with 111In-oxine (10-12 MBq) or 99mTc-HMPAO (300 MBq). Evaluation of the process activity is done on the ground activity index adopted which is received after the computer processing of the results. Three levels of process activity are determined: 1) when the leukocyte accumulation (LA) corresponds to that in the bone marrow; 2) when the LA corresponds to that in the liver; 3) when the LA corresponds to that in the spleen. The recorded sensitivity, specificity and accuracy of the method amount to 87.5%, 100% and 92.9% respectively. The method allows localization of the inflammatory process and indicates the degree of affecting the intestines. 2 figs., 6 refs

  11. Tomographically computed x-ray studies on the subcutaneous fatty layer of the lower abdominal plane

    (1) The cross-sectional area in the adult lower abdomen increased with age until a certain age and it decreased rapidly with old age in male, but there was little decreasing tendency in old age in female. (2) As for the cross-sectional area of the various tissue layers, that of the abdominal cavity was the greatest for both upper and lower planes, and this was followed by the subcutaneous fatty layer, muscular layer, osseous layer, in terms of size, in the upper plane. On the other hand, the cross-sectional area of the abdominal cavity was followed in size by the muscular layer in males and the subcutaneous fatty layer in females in the lower plane. (3) Concerning the age-related changes of the cross-sectional areas of the various tissue layers, it was observed in the elderly subjects that the males showed decreasing tendencies in the cross-sectional areas of the abdominal cavity and subcutaneous fatty layer, while the females showed increasing tendencies in the abdominal cavity but decreasing tendencies in the subcutaneous fatty layer. (4) As for the subcutaneous fatty layer thicknesses in the cross-sectional area, the gluteal line area was the largest and followed by the lumbar area in the upper plane. In contrast to this, in the lower plane, the thickness in the gluteal region was the largest for both males and females, and this was followed by the lumbar line region in males and the lateral line region in females. (5) As for the female minors, the total cross-sectional areas were 70 % of that of the adults, and the cross-sectional areas of the respective tissue layers also showed the same proportions under 10 years old. In the teenagers, too, the total cross-sectional areas were considerably smaller compared to the adults, but the cross-sectional areas of the various tissue layers were roughly equal to the adults except for the abdominal cavity area which alone was smaller.

  12. Secondary abdominal pregnancy and its associated diagnostic and operative dilemma: three case reports

    Gupta Pratiksha

    2009-08-01

    Full Text Available Abstract Introduction Abdominal pregnancy is extremely rare and has historically been defined as an implantation in the peritoneal cavity, exclusive of tubal, ovarian or intraligamentary pregnancy. Case presentations Three cases are reported. All came from a lower middle-income group and all of them were subjected to surgery. The first patient was a 30-year-old woman, who was pregnant for the fourth time, who presented at 16 weeks with an abdominal pregnancy. She was admitted with constant abdominal pain and retention of urine. She was hemodynamically stable and was administered a pre-operative intramuscular injection of methotrexate. During laparotomy she had only minor blood loss, the major part of the placenta was removed easily and she did not require any blood transfusion. Serum beta human chorionic gonadotrophin values and ultrasound follow-up revealed a normal study four weeks after surgery. The second patient was a 26-year-old woman, pregnant for the third time, admitted at 14 weeks with an abdominal pregnancy with hemoperitoneum, and the third patient was a 24-year-old woman, pregnant for the first time, who presented at 36 weeks gestation. She was only diagnosed as having an abdominal pregnancy during surgery, experienced excessive blood loss and required a longer hospital stay. Conclusions We hypothesize that treatment with pre-operative systemic methotrexate with subsequent laparotomy for removal of the fetus and placenta may minimize potential blood loss, and would be a reasonable approach in the care of a patient with an abdominal pregnancy with placental implantation to the abdominal viscera and blood vessels. This treatment option should be considered in the management of this potentially life-threatening condition. During surgery, if the placenta is attached to vital organs it should be left behind. Early diagnosis can help in reducing associated maternal morbidity and mortality.

  13. New technique for treating abdominal surgical site infection using CT woundgraphy and NPWT: A case report

    Introduction Negative pressure wound therapy (NPWT) for abdominal surgical site infection (SSI) is becoming increasingly common, although enterocutaneous fistula (ECF) has been reported as a complication. To avoid ECF, we used computed tomography (CT) woundgraphy to evaluate the relationship between the wound and the intestine, and then safely treated the abdominal SSI with NPWT. Case presentation Following a laparoscopic intersphincteric resection for low rectal neuroendocrine tumor and covering ileostomy, a 59-year-old woman underwent stoma closure. Six days after surgery, we diagnosed SSI. We suspected ECF, because the wound was deep and the pus resembled enteric fluid. However, CT woundgraphy showed that the wound was separated from the abdominal cavity and the intestine by the abdominal rectus muscle. Accordingly, we performed NPWT. SSI was cured and the wound was well granulated. Twenty-three days after surgery, the patient was discharged. Eventually, the wound was completely epithelialized. Discussion Although successful NPWT has been reported for open abdominal wounds, ECF is a common complication. ECF can be prevented by separating the wound from the intestine by the omentum or muscle fascia, protecting the intestinal serosa during surgery, and applying low vacuum pressure. The relationships among the wound, the fascia, and the intestine must be evaluated before abdominal SSI treatment. One good method is CT woundgraphy, which evaluates wound extent and depth, closure of muscle fascia, and the relationship between the wound and the intestine. Conclusion We report a case of CT woundgraphy before NPWT for abdominal SSI. CT woundgraphy is a good candidate for evaluating wound condition. PMID:27002290

  14. Retained intra-abdominal artery forceps – An unusual cause of intestinal strangulation

    2011-07-01

    Full Text Available Context: Surgical instruments and materials continue to be retained in the peritoneal cavity despite precautionary measures. Even though uncommon it is also under-reported and carries serious medico-legal consequences. Gauzes and sponges (gossypiboma are the most commonly retained materials and intra-abdominal retained artery forceps are much rarer but when they do occur lead to chronic abdominal pain and can be a rare cause of intestinal obstruction or strangulation with significant morbidity and mortality. Case Report: We present a case of intraabdominal retained artery forceps in a 70-years-old lady who underwent laparotomy with splenectomy for a large spleen in a peripheral hospital. Upon discharge she continued to complain of intermittent abdominal pain of increasing severity. 12 months later she presented to us with an acute (surgical abdomen requiring another laparotomy. At laparotomy she had strangulated/gangrenous lower jejunual and upper ileal bowel loops, the small bowel mesentery of this area being tightly trapped between the jaws of the retained artery forceps. She had gut resection and enteroanastomosis. Unfortunately she died from continuing sepsis on the second post-operative day. Conclusion: Retained instruments in intra-abdominal surgery can cause serious complication and should be treated surgically. High index of suspicion and appropriate investigations like plain abdominal X-ray, abdominal ultrasound and CT and MRI scans should be instituted in patients who develop chronic abdominal symptoms following laparotomy. Preventive measures against retained instruments must follow strict laid down protocols for surgical instruments handling in theatre.

    Yamada, Sohsuke; Tanimoto, Akihide; Matsuki, Yasumasa; Hisada, Yuji; Sasaguri, Yasuyuki

    2009-09-01

    A case of sclerosing encapsulating peritonitis (SEP) associated with liver cirrhosis (LC) and complicated by diffuse large B-cell lymphoma (DLBCL) is reported herein. A 49-year-old Japanese man had undergone peritoneo-venous shunt against refractory ascites due to hepatitis C virus-positive uncompensated LC for 2 years. After he received a diagnosis of DLBCL of the left neck lymph node 3 months before his death, palliative care was given because of his poor general condition. He developed severe abdominal distention and pain over 1 week and was found to have marked ascites and whole bowel lumped together on abdominal CT. At autopsy, the peritoneum was covered with a thick white membrane and the bowel could not be distinguished, which was macroscopically characterized by a cocoon-like appearance. Histology indicated a proliferation of diffusely thickened or hyalinized fibrocollagenous tissue in the entire peritoneum with a slight chronic inflammatory infiltrate and without remarkable change of mucosa. A diagnosis of SEP, also known as abdominal cocoon, was established based on these features. Additionally, in the abdominal cavity, a large amount of serous ascites and multiple peritoneal nodules or masses involved by DLBCL were recognized. To the authors' knowledge this is the first case report of SEP associated with LC and complicated by the invasion of DLBCL in the abdominal cavity. PMID:19712139

    2008-01-01

    A select group of patients with major stomal problems may benefit from operative modification of the abdominal wall. Options may include a modified abdominoplasty (abdominal wall contouring), localized flaps, or liposuction. Although frequently successful, these techniques have the potential for significant morbidity.

  19. Hypoxia inhibits abdominal expiratory nerve activity.

    Fregosi, R F; Knuth, S L; Ward, D K; Bartlett, D

    1987-07-01

    Our purpose was to examine the influence of steady-state changes in chemical stimuli, as well as discrete peripheral chemoreceptor stimulation, on abdominal expiratory motor activity. In decerebrate, paralyzed, vagotomized, and ventilated cats that had bilateral pneumothoraces, we recorded efferent activity from a phrenic nerve and from an abdominal nerve (cranial iliohypogastric nerve, L1). All cats showed phasic expiratory abdominal nerve discharge at normocapnia [end-tidal PCO2 38 +/- 2 Torr], but small doses (2-6 mg/kg) of pentobarbital sodium markedly depressed this activity. Hyperoxic hypercapnia consistently enhanced abdominal expiratory activity and shortened the burst duration. Isocapnic hypoxia caused inhibition of abdominal nerve discharge in 11 of 13 cats. Carotid sinus nerve denervation (3 cats) exacerbated the hypoxic depression of abdominal nerve activity and depressed phrenic motor output. Stimulation of peripheral chemoreceptors with NaCN increased abdominal nerve discharge in 7 of 10 cats, although 2 cats exhibited marked inhibition. Four cats with intact neuraxis, but anesthetized with ketamine, yielded qualitatively similar results. We conclude that when cats are subjected to steady-state chemical stimuli in isolation (no interference from proprioceptive inputs), hypercapnia potentiates, but hypoxia attenuates, abdominal expiratory nerve activity. Mechanisms to explain the selective inhibition of expiratory motor activity by hypoxia are proposed, and physiological implications are discussed. PMID:3624126

  3. Fetal abdominal magnetic resonance imaging

    This review deals with the in vivo magnetic resonance imaging (MRI) appearance of the human fetal abdomen. Imaging findings are correlated with current knowledge of human fetal anatomy and physiology, which are crucial to understand and interpret fetal abdominal MRI scans. As fetal MRI covers a period of more than 20 weeks, which is characterized not only by organ growth, but also by changes and maturation of organ function, a different MR appearance of the fetal abdomen results. This not only applies to the fetal intestines, but also to the fetal liver, spleen, and adrenal glands. Choosing the appropriate sequences, various aspects of age-related and organ-specific function can be visualized with fetal MRI, as these are mirrored by changes in signal intensities. Knowledge of normal development is essential to delineate normal from pathological findings in the respective developmental stages

    2015-11-01

    A vertical-external-cavity surface-emitting-laser is demonstrated in the terahertz range, which is based upon an amplifying metasurface reflector composed of a sub-wavelength array of antenna-coupled quantum-cascade sub-cavities. Lasing is possible when the metasurface reflector is placed into a low-loss external cavity such that the external cavity—not the sub-cavities—determines the beam properties. A near-Gaussian beam of 4.3° × 5.1° divergence is observed and an output power level >5 mW is achieved. The polarized response of the metasurface allows the use of a wire-grid polarizer as an output coupler that is continuously tunable.

  7. Experimental investigation of cavity flows

    Loeland, Tore

    1998-12-31

    This thesis uses LDV (Laser Doppler Velocimetry), PIV (Particle Image Velocimetry) and Laser Sheet flow Visualisation to study flow inside three different cavity configurations. For sloping cavities, the vortex structure inside the cavities is found to depend upon the flow direction past the cavity. The shape of the downstream corner is a key factor in destroying the boundary layer flow entering the cavity. The experimental results agree well with numerical simulations of the same geometrical configurations. The results of the investigations are used to find the influence of the cavity flow on the accuracy of the ultrasonic flowmeter. A method to compensate for the cavity velocities is suggested. It is found that the relative deviation caused by the cavity velocities depend linearly on the pipe flow. It appears that the flow inside the cavities should not be neglected as done in the draft for the ISO technical report on ultrasonic flowmeters. 58 refs., 147 figs., 2 tabs.

  8. Imaging of the peritoneal cavity in CAPD.

    Wankowicz, Z; Pietrzak, B; Skrobowska, E

    1996-01-01

    The aim of our study was the use of the optimal imaging of the peritoneal cavity (PC) for continuous ambulatory peritoneal dialysis (CAPD)-related problems. Ultrasonography (USG), direct abdominal radiography (DAR), peritoneoscintigraphy (PSG), and standard peritoneo-computed tomography (PCT) with reconstruction (R-PCT) were performed in 25 patients on CAPD from three to 44 months. Studies were done at the beginning of CAPD (1-3 months) as well as in the noncomplicated and complicated course of CAPD. Group 1 comprised 17 patients in whom 77 PC images were taken in the non-complicated course of CAPD. Group II comprised 15 patients in whom 65 images were taken during or after complications. For USG and DAR we used standard equipment, PSG was done with sulfur colloid labeled with technetium 99m (Tc 99m), PCT, and R-PCT were done with Omnipaque and Somatom HiQ Siemens unit. In PCT, two- and three dimensional reconstruction were done by our own computer program. USG was recommended for imaging of tunnel infections, exit-site infection (ESI), and adhesion. PSG was useful in almost all observed complications of CAPD except thickening of the peritoneal membrane (PM). Standard PCT with R-PCT was more useful than PCT because of a more legible image of the peritoneal cavity, which gives the possibility of monitoring fluid distribution and measuring of intraperitoneal fluid volume.

  16. Abdominal ultrasonographic findings of Yersiniosis in children

    To review abdominal ultrasonography in Yersinia Pseudotuberculosis(YP) infection. From June 1993 through June 1994, abdominal ultrasonograms were reviewed in 36 patients with YP infection. The age of patients was from 4 to 14 years. A diagnosis of YP infection was made on the basis of isolation of YP from stool (n=15/36, 41.7%) and by documenting at least a minimum agglutination antibody titer of 1;160 or greater (n=34/36, 94.4%). Abdominal US findings were identified in 33/36 (91.7%) of patients with YP infection. US abnormalities included right lower quadrant abdominal lymphadenopathy in 28/36 (77.8%) of cases: increased bilateral renal cortical echogenecity with renal enlargement, 11/36 (30.6%) of cases:hepatosplenomegaly, 6/36 (16.7%) of cases: bowel wall thickening in termnal ileum and cecum, 4/36 (11.1%) of cases:and ascites, 2/36 (5.5%) of cases. Three patients revealed no abdominal sonographic finding. We conclude that abdominal US can help in the diagnosis of YP infection when US demonstrates multiple right lower quadrant abdominal lymphadenopathy, increased renal cortical echogenecity with renal enlargement, hepatosplenomegaly, intestinal wall thickening or ascites

  17. Radiologic findings of abdominal wall endometriosis

    To evaluate the imaging findings of abdominal wall endometriosis. In seven of 17 patients with surgically proven endometriosis of the abdominal wall, we retrospectively reviewed the findings of radiologic studies such as abdominal US (n=3), CT (n=4), and MRI (n=1). One patient under went more than one type of imaging, apparently. The surgical history of the seven, and their symptoms and preoperative diagnosis were reviewed, and the size, location, margin and nature of the mass, and the contrast enhancement patterns observed at radiologic studies, were assessed. The chief symptoms were palpable abdominal wall mass (n=5) and lower abdominal pain (n=2) around a surgical scar. Previous surgery included cesarean section (n=5), cesarean section with oophorectomy (n=1) and appendectomy (n=1). Masses were located in the subcutaneous fat layer (n=5) or rectus abdominis muscle (n=2), and their maximum diameter was 2.6 cm. Imaging findings, which correlated closely with the pathologic findings, included a well (n=5) or poorly marginated (n=2) solid mass, with a focal cystic area apparent in two cases. Although imaging findings of abdominal wall endometriosis may not be specific for diagnosis, the presence of a solid abdominal mass in female patients of reproductive age with a history of surgery is a diagnostic pointer

    We report a case of combined subcutaneous, intrathoracic, and abdominal splenosis who presented with attacks of flushing, tachycardia and vague abdominal pain. The patient's past medical history included a splenectomy due to abdominal trauma and years later, a lung lobectomy due to recurrent pneumonia. An enhancing solid mass adjacent to the upper pole of the left kidney and nodular pleural based lesions in the left hemi-thorax along with nodular lesions in subcutaneous tissue of the left chest wall suggested possible adrenal malignancy with multiple metastases. Histopathologic examination demonstrated benign lesions of ectopic splenic tissue. PMID:20804314

    A 73-year-old man was transferred for treatment of abdominal aortic aneurysm. He had no history of abdominal surgeries. Grafting between the infra-renal abdominal aorta and the bilateral common iliac arteries was performed. Proximal and distal cross clamps were applied for grafting. He developed chylous ascites on the 5th post-operative day, 2 days after initiation of oral intake. Fortunately, he responded to treatment with total parenteral hyper-alimentation for 10 days, followed by a low-fat diet. There was no recurrence of ascites. PMID:27087873

  3. Seamless/bonded niobium cavities

    Singer, W.

    2006-07-01

    Technological aspects and performance of seamless cavities produced by hydroforming are presented. Problems related to the fabrication of seamless cavities from bulk niobium are mainly solved thanks to the progress of the last years. The highest achieved accelerating gradients are comparable for both seamless and welded versions (ca. 40 MV/m) Nevertheless further development of seamless cavities is desirable in order to avoid the careful preparation of parts for welding and get reliable statistic. Fabrication of NbCu clad cavities from bimetallic tubes is an interesting option that gives new opportunity to the seamless technique. On the one hand it allows reducing the niobium costs contribution; on the other hand it increases the thermal stability of the cavity. The highest accelerating gradient achieved on seamless NbCu clad single cell cavities (ca. 40 MV/m) is comparable to the one reached on bulk Nb cavities. Fabrication of multi-cell NbCu cavities by hydroforming was recently proven.

  4. Risk of Essure microinsert abdominal migration: case report and review of literature

    Full Text Available Giuseppe Ricci,1,2 Stefano Restaino,2 Giovanni Di Lorenzo,1 Francesco Fanfani,1 Federica Scrimin,1 Francesco P Mangino1 1Institute for Maternal and Child Health, IRCCS “Burlo Garofolo”, Trieste, Italy; 2Department of Medical Sciences, University of Trieste, Trieste, Italy Purpose: To report a case of Essure microinsert abdominal migration and literature review.Methods: A 41-year-old woman was counseled to undergo Essure sterilization. The procedure was hampered by the presence of endometrial cavity adhesions, obscuring left tubal ostium. By using microscissors the adhesions were progressively lysed. Since the procedure had become very painful, the patient required general anesthesia. Once adhesion lysis was completed, the tubal ostium was well visible. Both devices were then easily introduced into the fallopian tubes. At the end of the procedure, five coils were visible on the right side and five coils on the left side, as recommended.Results: The 3-month hysterosalpingogram follow-up suspected abdominal migration of the left device. Laparoscopy confirmed the device displacement in the left lower abdominal quadrant. Both fallopian tubes and the uterus appeared normal. No signs of perforation were detected. The device was embedded into the omentum, but it was easily removed. Bilateral tubal sterilization was performed by bipolar coagulation.Conclusion: There are only 13 cases, including the present, of Essure abdominal migration in the literature. In most cases, abdominal displacement of the microinsert is asymptomatic and does not induce tissue damage. However, in some cases, it may cause a severe adverse event, requiring major surgery. Therefore, removal of the migrated device should be performed as soon as possible. Moreover, during presterilization counseling, the patient should also be correctly informed about the risk of this rare but relevant complication, as well as about the surgical interventions that could be required to solve it

  5. Multiple abdominal nodules in a patient with ulcerative proctitis: a case of peritoneal splenosis

    Margherita Marocchi

    2013-03-01

    Full Text Available A 40-year old gardener was referred for ulcerative proctitis treated with topical mesalamine with rapid improvement of symptoms. Eighteen years before he had had a splenectomy for traumatic splenic rupture. At the end of 2010, he was admitted to another hospital because of abdominal pain. Computerized tomography (CT scan and magnetic resonance imaging revealed multiple abdominal nodules but a definite diagnosis was not made. While being examined for the proctitis, the patient was admitted to our unit due to worsening of the abdominal pain. After another CT scan, a laparoscopy was performed: several reddish-blue nodules on the peritoneal wall were observed and biopsies were performed. Histological examination was consistent with splenosis. After the procedure, we observed an improvement in the abdominal pain. Splenosis is an acquired condition defined as autotransplantation of viable splenic tissue throughout different sites of the body. It occurs after splenic rupture via trauma or surgery. Splenosis is a benign condition that is usually found incidentally unless symptomatic. Since on radiographic examination it can mimic a neoplasia, extensive workup is usually needed. The diagnostic method of choice is nuclear scintigraphy. Splenosis usually occurs in the abdominal and pelvic cavities but patients have been described with splenosis in other intrathoracic, hepatic and subcutaneous sites. Splenosis is usually asymptomatic and treatment is not necessary. Most patients who have an exploratory laparotomy or laparoscopy for abdominal pain, such as in our patient, experience no more pain after the procedure, regardless of whether the splenic nodules have been completely removed or not. The reason for this spontaneous improvement is not known.

  7. Staging of pediatric abdominal malignancies

    The scope of this review is the role of CT in the staging of childhood solid abdominal malignancies. Owing to the limitations of space, only the commonest lesions will be discussed in detail: Wilms' tumor, neuroblastoma, and liver tumors. The TNM staging system has been utilized throughout this monograph. It will not be used in this chapter, however, since in this country different staging systems individualized to each pediatric tumor have been developed. These staging systems take into account the different biology of each tumor and have clear correlations with prognosis and therapeutic programs. The discussion centers almost exclusively on the role of CT in the staging and management of neoplastic processes in children. The information required for staging can sometimes be obtained by other imaging modalities (i.e., ultrasound, excretory urography, etc.) The choice of modality will be strongly influenced by techniques and expertise available as well as by the bias of the institution. An additional factor to be taken into consideration will be the economic factor. Prospective reimbursement will strongly encourage the use of tests that are cost-effective and clinically efficacious

  12. Adhesive intestinal obstruction following blunt abdominal trauma

    Advances in diagnosis and management of multiple trauma patients have lead to adopting a conservative approach for most patients with blunt abdominal trauma. Intestinal obstruction is a rare complication for this approach. Herein, we report a 37-year-old male, who did not have an abdominal operation, and who developed adhesive intestinal obstruction 7 weeks following blunt abdominal trauma. We detected no signs of peritonitis or intra-abdominal bleeding clinically or radiologically on admission. We initially treated the intestinal obstruction conservatively, but the obstruction did not resolve. Finally, we performed laparotomy, which showed that the small bowel was matted together by thick fibrous layers of adhesions. We performed adhesiolysis, and the patient was discharged home 3 weeks later. Histopathological findings of the fibrous layer were consistent with repair due to previous trauma and hemorrhage. We review the literature of this rare condition. (author)

    1999-08-01

    A traumatic pseudoaneurysm of the abdominal aorta is a rare entity, occurring as the result of a missed aortic lesion at the time of the initial injury. Therefore, clinical suspicion and careful abdominal exploration at first laparotomy is mandatory to prevent aortic pseudoaneurysm formation and its risk of delayed rupture. We present a case of successful surgical treatment of a suprarenal aortic false aneurysm, presenting 4 weeks after a life-threatening gunshot wound in a 13-year-old child. PMID:10499389

    A 68-year-old woman presented a rare lateral abdominal wall hernia. Three month before admission to Chungbuk National University Hospital, she found a large protruding mass measuring 8 cm in diameter in the midaxillary line just below the costal margin upon heavy coughing. She had no history of abdominal trauma, infection, or operation previously. The mass was easily reduced manually or by position change to left lateral decubitus. CT scan showed a defect of the right transversus abdominis mu...

  5. Anesthetic Considerations for Abdominal Wall Reconstructive Surgery

    Slabach, Rachel; Suyderhoud, Johan P.

    2012-01-01

    Anesthesia considerations for abdominal wall reconstruction (AWR) are numerous and depend upon the medical status of the patient and the projected procedure. Obesity, sleep apnea, hypertension, and cardiovascular disease are not uncommon in patients with abdominal wall defects; pulmonary functions and cardiac output can be affected by the surgical procedure. Patients with chronic obstructive pulmonary disease are also at a higher risk of coughing during the postoperative awakening process, wh...

    2015-01-01

    We report a case of intra-abdominal testicular torsion, of eight years old boy who presented with asymptomatic left impalpable testis. Diagnostic laparoscopy revealed a twisted small intra-abdominal testis in which the spermatic cord twisted 3 times over a band attached to the internal ring. The cord was long enough to bring the small testis into the scrotal sac. This case highlights the pole of laparoscopy in the management of impalpable testes.

  7. Diagnosis and treatment of expanding haematoma of the lateral abdominal wall after blunt abdominal trauma

    We report a rare case of an expanding post-traumatic lateral abdominal wall haematoma. A superselective arteriogram of the deep circumflex iliac artery showed extravasation from the ascending branch, urging emergency therapy. Microcoil and Gelfoam embolisation was successfully performed. Haematomas of the abdominal wall can be divided in the common rectus sheath haematomas and the rare haematomas of the lateral abdominal wall. Differentiating both entities is essential, since there is a strong difference in their vascular supply. The typical vascular supply of the lateral abdominal wall is discussed, with emphasis on the ascending branch of the deep circumflex iliac artery. (orig.)

  9. Entangling atoms in bad cavities

    Sorensen, Anders S.; Molmer, Klaus

    2002-01-01

    We propose a method to produce entangled spin squeezed states of a large number of atoms inside an optical cavity. By illuminating the atoms with bichromatic light, the coupling to the cavity induces pairwise exchange of excitations which entangles the atoms. Unlike most proposals for entangling atoms by cavity QED, our proposal does not require the strong coupling regime g^2/\\kappa\\Gamma>> 1, where g is the atom cavity coupling strength, \\kappa is the cavity decay rate, and \\Gamma is the dec...

  10. Abdominal tuberculosis: clinical presentation and outcome

    To study the clinical presentation and outcome of cases of Abdominal Tuberculosis. Fifty four patients of Abdominal Tuberculosis were seen during the study period. Four patients were lost to follow-up, which were excluded. Detailed information of all the patients including age, sex, symptoms, signs, investigations and management was recorded, analyzed and compared with local and international data. Out of the 50 patients with Abdominal Tuberculosis, 31 were females and 19 males. Their ages ranged from 17 to 63 years, with a mean age of 25.1 years. Thirty five cases were admitted through Emergency and 15 through Outpatients departments. Abdominal pain was the most common symptom found in 44 (88%) patients followed by vomiting in 33 (66%). Abdominal tenderness was seen in 22 (44%) patients, while 16 (32%) patients had rigidity and other features of peritonitis. Surgery was performed in all these patients, limited right hemicolectomy in 17 (34%), segmental resection and anastomosis in 12 (24%), ileostomy and strictureplasty in six (12%) each, repair of perforation in five (10%) and adhesiolysis in four (8%) patients. Overall mortality was 8% due to septicaemia and multiorgan failure. Abdominal Tuberculosis is a significant clinical entity with lethal complications in neglected cases. It affects a younger age group and is more common in females. Clinical features are rather non-specific but vague ill health, low grade fever, weight loss and anorexia may help to diagnose the case.

  11. Effect of rectal distension on abdominal girth.

    Marino, B; Ogliari, C; Basilisco, G

    2004-08-01

    It has been postulated that a viscerosomatic reflex activated by gut distension and inhibiting abdominal wall muscle tone may be one of the mechanisms underlying functional abdominal distension. Any demonstration of such a reflex has to take into account the fact that gut distension may increase abdominal girth as a result of volume displacement. As biomechanical and sensory rectal responses vary at different rates of rectal distension, we hypothesized that different rates of rectal distension might reveal different changes in abdominal girth. Abdominal girth was continuously recorded in 14 healthy subjects using a previously validated extensometer. The rectal distensions were made in a randomized order at rates of 100 mL min(-1) or 10 mL min(-1) up to 150 mL, and sham distensions were used as controls. An increase in abdominal girth was observed at the end of both distensions (P

  12. Factors associated with abdominal obesity in children

    2015-12-01

    Full Text Available Objective: To identify the association of dietary, socioeconomic factors, sedentary behaviors and maternal nutritional status with abdominal obesity in children. Methods: A cross-sectional study with household-based survey, in 36 randomly selected census tracts in the city of Santos, SP. 357 families were interviewed and questionnaires and anthropometric measurements were applied in mothers and their 3-10 years-old children. Assessment of abdominal obesity was made by maternal and child's waist circumference measurement; for classification used cut-off points proposed by World Health Organization (1998 and Taylor et al. (2000 were applied. The association between variables was performed by multiple logistic regression analysis. Results: 30.5% of children had abdominal obesity. Associations with children's and maternal nutritional status and high socioeconomic status were shown in the univariate analysis. In the regression model, children's body mass index for age (OR=93.7; 95%CI 39.3-223.3, female gender (OR=4.1; 95%CI 1.8-9.3 and maternal abdominal obesity (OR=2.7; 95%CI 1.2-6.0 were significantly associated with children's abdominal obesity, regardless of the socioeconomic status. Conclusions: Abdominal obesity in children seems to be associated with maternal nutritional status, other indicators of their own nutritional status and female gender. Intervention programs for control of childhood obesity and prevention of metabolic syndrome should consider the interaction of the nutritional status of mothers and their children.

  13. Cavity Backed Slot Antenna

    Sarang Masani, Ila Parmar, Hitendra Jadeja

    2013-05-01

    Full Text Available Among the current driving forces in wireless communications, there is a need for compact, efficient, inexpensive and reproducible antennas. In some instances, particularly long-distance applications, radiators with directive, high-gain characteristics are necessary. This paper proposes a cavity-backed slot antenna to that end. This antenna will enhance the gain, directivity and can also be easily flush mounted to the flying object. The shape and size of the slot can be effectively utilized to get the desired result. The proposed antenna is feed by waveguide which facilitate it to be applicable at high power operation where coaxial cable fails due to skin effect. Present antenna is verified using Numerical Technique called Finite Element Method FEM. The conception of this antenna is realized by the software HFSS “Ansoft-High Frequency Structure Simulator”. By properly selecting shapes, dimensions of the slots and number of slot affects the parameters like return loss, gain along Θ, Ø directions, Cartesian plot and radiation pattern .The Backing of cavity to the slot antenna provide the basics of the gain enhancement and the slot loading effect and the cavity volume plays an important role in achieving the desired return loss at the specific frequency.The simulated antenna shows the 7.0944 db of gain and return loss of -28.60. The proposed antenna works at 6 GHz.

  14. US anatomy of the great peritoneal cavity and its recesses

    The peritoneum of the great abdominal cavity and its recesses are a blind radiographical area which can however be easily outlined by US when it contains fluid. The anatomical study of these usually virtual cavities represent the purpose of this paper. The natural contrast of the peritoneal fluid as amplified by the mechanical effect produced by an adequate amount of fluid, allows a clear visualization of the anatomy of various peritoneal structures in either upper (subphrenic, subhepatic, lesser sac, etc.) or lower (pelvic) areas. The sovramesocolic and the infracolic compartments are in comunication through the two external paracolic gutters which are the main passageways for the fluids between upper and lower compartments. In fact, peritoneal fluids are in constant movement due to different factors, such as gravity, statics, which causes the peritoneal fluids to flow into the lowest part of the peritoneal cavity, and hydrostatic pressure. Pressure differences are thought to convey fluids from various sites of the abdomen into different areas. In the lower abdomen, pressure is 3 times as much as in the upper abdomen, which causes the fluids to move into the subhepatic and subphrenic regions. The redistribution of fluids can be influenced by particular anatomical causes. The phrenicocolic ligament, e.g., is a barrier to the advancing of fluds along the left paracolic gutter, which makes the right paracolic gutter the main passageway for the fluids. This pattern explains why abscesses are more frequent in the right than in the upper left abdominal regions. Another example in the tiny Winslow opening, which does not allow inflammatory material to pass into the lesser sac in case of inflammatory processes of the great peritoneal cavity and viceversa. Moreover, pointing out fluid collections and abscesses is important, since an early diagnosis and a topografic map are essential order to plan treatment

  15. Crab Cavities for Linear Colliders

    Crab cavities have been proposed for a wide number of accelerators and interest in crab cavities has recently increased after the successful operation of a pair of crab cavities in KEK-B. In particular crab cavities are required for both the ILC and CLIC linear colliders for bunch alignment. Consideration of bunch structure and size constraints favour a 3.9 GHz superconducting, multi-cell cavity as the solution for ILC, whilst bunch structure and beam-loading considerations suggest an X-band copper travelling wave structure for CLIC. These two cavity solutions are very different in design but share complex design issues. Phase stabilisation, beam loading, wakefields and mode damping are fundamental issues for these crab cavities. Requirements and potential design solutions will be discussed for both colliders.

    Drainage of thoracic cavity is a routine treatment for traumatic pleural effusion or pneurnothorax, whereas improper operation may cause serious consequences, A case of 47-year-old man with traffic injury is reported herein. The patient had abdominal pain, chest distress, and trouble breathing when admitted to our hospital. After admission, the patient's blood pressure decreased, heart rate increased and blood was draw upon from the chest tubes. Chest examination indicated wet rales in both sides and decreased breath sounds in the left side. Abdominal examination reversed peritonitis symptoms. Abdominal X-ray indicated there were free gas under left hernidia-phragm and moderate amount of left pleural effusion. The abdominal computed tomography (CT) scan showed pleural drainage tube in the abdominal cavity which was closely related to spleen. We made diagnosis as following: ①multiple injuries caused by traffic injury;②diaphragmatic injury;③splenic rupture.

  20. Malignant Mesothelioma Presenting as a Giant Chest, Abdominal and Pelvic Wall Mass

    Shao, Zhi Hong; Gao, Xiao Long; Yi, Xiang Hua; Wang, Pei Jun [Tongji Hospital of Tongji University, Shanghai (China)

    2011-11-15

    Malignant mesothelioma (MM) is a relatively rare carcinoma of the mesothelial cells, and it is usually located in the pleural or peritoneal cavity. Here we report on a unique case of MM that developed in the chest, abdominal and pelvic walls in a 77-year-old female patient. CT and MRI revealed mesothelioma that manifested as a giant mass in the right flank and bilateral pelvic walls. The diagnosis was confirmed by the pathology and immunohistochemistry. Though rare, accurate investigation of the radiological features of a body wall MM may help make an exact diagnosis.

  2. The therapeutic impact of abdominal ultrasound in patients with acute abdominal symptoms

    AIM: The technical performance of abdominal ultrasound in the investigation of acute abdominal pain has been thoroughly investigated but its therapeutic effects are less well understood. We aimed to determine the therapeutic effect of abdominal ultrasound in the investigation of acute abdominal pain. MATERIAL AND METHODS: A pre- and post-intervention observational study design was used to determine the diagnostic and therapeutic effects of abdominal ultrasound for acute abdominal pain. Referring clinicians completed a pre-ultrasound questionnaire that detailed their leading diagnosis, confidence in this and intended management in 100 consecutive adult patients. Following ultrasound a second questionnaire was completed. This again detailed the leading diagnosis, confidence in this and their intended management. Clinicians quantified the management contribution of ultrasound both for the individual case in question and in their clinical experience generally. RESULTS: The leading diagnosis was either confirmed or rejected in 72 patients and a new diagnosis provided where no prior differential diagnosis existed in 10. Diagnostic confidence increased significantly following ultrasound (mean score 6·5 pre-ultrasound vs 7·6 post-ultrasound, P < 0·001). Intended management changed following ultrasound in 22 patients; 15 intended laparotomies were halted and a further seven patients underwent surgery where this was not originally intended. Ultrasound was rated either 'very' or 'moderately' helpful in 87% of patients, with 99% of clinicians finding it either 'very' or 'moderately' helpful generally. CONCLUSION: Abdominal ultrasound has considerable diagnostic and therapeutic effect in the setting of acute abdominal pain. Dhillon, S. et al. (2002)

    2008-01-01

    We report a case of abdominal eventration associated with cystic fibrosis, diagnosed by mid-trimester ultrasonography. The defect concerned the abdominal muscles and their aponevrotic sheath, but respected the skin. There was no associated malformation. The outcome was favorable after surgery, and the infant is well at the age of 6 months. PMID:18046068

  4. ISR RF cavities

    1983-01-01

    In each ISR ring the radiofrequency cavities were installed in one 9 m long straight section. The RF system of the ISR had the main purpose to stack buckets of particles (most of the time protons)coming from the CPS and also to accelerate the stacked beam. The installed RF power per ring was 18 kW giving a peak accelerating voltage of 20 kV. The system had a very fine regulation feature allowing to lower the voltage down to 75 V in a smooth and well controlled fashion.

  5. CT diagnosis of abdominal ectopic pheochromocytoma

    Objective: To discuss the value of CT in diagnosis of abdominal ectopic pheochromocytoma. Methods: CT findings of 5 cases surgically and pathologically proved with ectopic pheochromocytoma were retrospectively analyzed. Results: Soft tissue mass with light asymmetry enhancement was found between the abdominal aorta and the inferior vena ca-va in one case. 1 case was completely cystic with light enhancement of the cystwall located in front of the left side of the abdominal aorta. 1 case of large solid mass occurred between the renal hilum and the tail of pancreas, with irregular shape, unclear boundary, central necrosis, calcification and obviously enhancement at the solid part. 2 cases showed as oval soft lump with even density, moderate strengthening located before the abdominal aorta. Paroxysmal hypertension occurred in 3 cases and didn't in 2 cases. Hypertension happened in 1 case during the operation because of stimulation. Blood pressure appeared in 1 case during and after operation. Blood and urinary catecholamine increased significantly in 4 cases. Conclusion: Ectopic pheochromocytoma mainly located surround the abdominal aorta with diverse CT performance. It is helpful for diagnosing when finding a lesion locates at the specified sites combined with typical clinical presentation. CT can not only depict small tumor, but also can show the relationship with surrounding structure, and it provides important information for the operation and prognosis. (authors)

  6. Abdominal tuberculosis, clinical-radiological revision

    We retrospectively evaluated the clinical charts and diagnostic images of hospitalised patients with histological or bacteriologic demonstration of abdominal tuberculosis (TB) including those with probable abdominal TB, who had pulmonary TB and radiologic findings highly suggestive of abdominal TB with favourable response to treatment. Cases with genitourinary TB were excluded. We found 24 patients with an average age of 25 yrs. In some cases this entity was not suspected on the imaging studies, and diagnosis was made on surgery. The most frequent symptoms were: abdominal pain, diarrhoea, fever, vomiting, weight loss and abdominal mass. Active pulmonary TB was demonstrated on 8 cases (33%) Peritoneal presentation was the most frequent (54%) with septated or simple ascites, cystic ascites or pseudocysts within bowel loops. Mesenteric involvement (21 %) showed adenopathy or masses identified with CT. Intestinal forms (17%) showed pseudo-polyps on terminal ileum and ulcers on ileum, cecum and colon. We found one case with diffuse ulcerative involvement of the colon. Two cases showed hepatic involvement, one with an abscess and a tuberculosis Cole cystitis, with pyloric syndrome due to fibrosis

  7. Paediatric emergencies: non-traumatic abdominal emergencies

    Presentation with acute abdominal pain or abdominal symptopathology is a very common cause of presentation of children to hospital. The causes are dependent in part on the age of the child, in part on the presence of previous surgery, and can be divided into those that relate to congenital abnormalities at whatever age they present, acquired disease and infection. Children, particularly young children are often poor historians, and therefore the clinical examination and the laboratory investigations are important in helping to come to a diagnosis. Primary imaging of abdominal emergencies in childhood is a radiograph of the abdomen, followed by ultrasound. Further imaging depends on the results of these studies. An ordered review of the abdomen radiograph is important if the salient features on X-ray are not to be missed. Practitioners should be competent with abdominal ultrasound in children and know where to seek the causes of disease, as these are different from those that are obtained in many instances in adults. Familiarity with the likely causes is important. The three commonest causes of acute abdominal pain in childhood are, in young infants, intussusception, appendicitis and mesenteric adenitis. In older children, inflammatory bowel disease and ovarian pathology are also included. This article details the approach to imaging and the salient features of some of the conditions. (orig.)

    2014-01-01

    This work describes the design, development and application of the system for frequency control of EMMA accelerator radiofrequency cavity. The problem with the radiofrequency cavities is, that because of various factors (change in the environmental temperature, mechanical stress, ...), they are continuously frequency detuning. The consequence of the frequency detuning is that electromagnetic field in the cavity is not optimal for the acceleration of the particles. For this reason the resonant...

  10. Single ion cavity QED experiments

    Full text: We have set up a spherical Paul trap for a storing a single Ca+ ion placed in the center of a high finesse near confocal resonator. We report on experiments demonstrating the coupling of the narrow S1/2-D5/2 transition to the cavity internal light field. Due to the coupling, the ion acts as sensitive probe for the cavity internal field. We are able to map the field distribution by measuring the excitation probability. Scanning the cavity over the resonance imprints a Doppler frequency shift on the cavity field which leads to a spectral shift and a asymmetric broadening of the S-D transition. (author)

  11. Cavity coalescence in superplastic deformation

    Stowell, M.J.; Livesey, D.W.; Ridley, N.

    1984-01-01

    An analysis of the probability distribution function of particles randomly dispersed in a solid has been applied to cavitation during superplastic deformation and a method of predicting cavity coalescence developed. Cavity size distribution data were obtained from two microduplex nickel-silver alloys deformed superplastically to various extents at elevated temperature, and compared to theoretical predictions. Excellent agreement occurred for small void sizes but the model underestimated the number of voids in the largest size groups. It is argued that the discrepancy results from a combination of effects due to non-random cavity distributions and to enhanced growth rates and incomplete spheroidization of the largest cavities.

    We propose and analyze a new type of a resonant high-Q cavity for lasing, sensing or filtering applications, which is based on a surface states of a finite photonic crystal. We demonstrate that such the cavity can have a Q factor comparable with that one of conventional photonic band-gap defect mode cavities. At the same time, the distinguished feature of the surface mode cavity is that it is situated directly at the surface of the photonic crystal. This might open up new possibilities for de...

  13. Nanofriction in Cavity Quantum Electrodynamics.

    Fogarty, T; Cormick, C; Landa, H; Stojanović, Vladimir M; Demler, E; Morigi, Giovanna

    2015-12-01

    The dynamics of cold trapped ions in a high-finesse resonator results from the interplay between the long-range Coulomb repulsion and the cavity-induced interactions. The latter are due to multiple scatterings of laser photons inside the cavity and become relevant when the laser pump is sufficiently strong to overcome photon decay. We study the stationary states of ions coupled with a mode of a standing-wave cavity as a function of the cavity and laser parameters, when the typical length scales of the two self-organizing processes, Coulomb crystallization and photon-mediated interactions, are incommensurate. The dynamics are frustrated and in specific limiting cases can be cast in terms of the Frenkel-Kontorova model, which reproduces features of friction in one dimension. We numerically recover the sliding and pinned phases. For strong cavity nonlinearities, they are in general separated by bistable regions where superlubric and stick-slip dynamics coexist. The cavity, moreover, acts as a thermal reservoir and can cool the chain vibrations to temperatures controlled by the cavity parameters and by the ions' phase. These features are imprinted in the radiation emitted by the cavity, which is readily measurable in state-of-the-art setups of cavity quantum electrodynamics. PMID:26684118

  14. Thoracic and abdominal blastomycosis in a horse.

    Toribio, R E; Kohn, C W; Lawrence, A E; Hardy, J; Hutt, J A

    1999-05-01

    A 5-year-old Quarter Horse mare was examined because of lethargy, fever, and weight loss of 1 month's duration. Thoracic auscultation revealed decreased lung sounds cranioventrally. Thoracic ultrasonography revealed bilateral anechoic areas with hyperechoic strands, consistent with pleural effusion and fibrin tags. A large amount of free fluid was evident during abdominal ultrasonography. Abnormalities included anemia, hyperproteinemia, hyperglobulinemia, hyperfibrinogenemia, and hypoalbuminemia. Thoracic radiography revealed alveolar infiltrates in the cranial and caudoventral lung fields. A cavitary mass, consistent with an abscess, could be seen caudodorsal to the crura of the diaphragm. Ultrasonographic evaluation of this area revealed a hypoechoic mass with septations. Bilateral thoracocentesis was performed. Bacterial culture of the pleural fluid did not yield growth, but Blastomyces dermatitidis was isolated from pleural fluid, abdominal fluid, and an aspirate of the abscess. The mare was euthanatized, and a diagnosis of thoracic and abdominal blastomycosis was confirmed at necropsy. PMID:10319179

  15. [Pediatric Abdominal Pain – Harmless or Harmful?].

    Furlano, Raoul Ivano

    2016-04-27

    Abdominal pain is a very common pediatric complaint. In the majority of cases there is no life-threatening pathology behind this symptom, but a functional disease. However, all-day activities of children and adolescents are often limited, frequent absences from school, and general physician/ pediatrician office visits with often unnecessary diagnostic and therapies are registered. Once an organic etiology of the abdominal pain is excluded by a thoroughly medical history taking and physical examination, the first steps for a successful alleviation of the pain is the reassurance of the patients and their family that there is no life-threatening pathology. There is evidence that cognitive-behavioral therapy may be useful in improving pain and disability outcome in the short term. There is no evidence for pharmacological, dietetic, or complementary intervention in the treatment of chronic functional abdominal pain. PMID:27120211

  16. Indium 111 leucocyte scintigraphy in abdominal sepsis

    We have studied the clinical utility of indium 111 autologous leucocyte scintigraphy retrospectively in 45 patients presenting with suspected intra-abdominal sepsis. The sensitivity was 95% (21/22) and the specificity was 91% (21/23). Some 34 of the studies (17 positive and 17 negative) were considered helpful in furthering patient management (76%) and 8, unhelpful (18%). In 3, the study results were misleading and led to inappropriate treatment.

  19. Upper abdominal trauma in children: imaging evaluation

    One hundred consecutive children with serious blunt upper-abdominal injury were evaluated prospectively to assess the accuracy and usefulness of emergency computed tomography (CT) compared with liver-spleen scintigraphy and sonography. Ninety-five hemodynamically stable patients were imaged. The results of this 20-month study indicated that CT has fewer false negatives and false positives than scintigraphy or sonography, that CT is useful in abdominal trauma, and that CT provides the most information of any single diagnostic imaging test commonly available

    Systemic lupus erythematosus(SLE) is a systemic disease of unknown etiology. Its main pathology is vasculitis and serositis, due to deposition of the immune complex or antibodies. Most findings are nonspecific ; abdominal manifestations include enteritis, hepatomegaly, pancreatic enlargement, serositis, lymphadenopathy, splenomegaly, nephritis, interstitial cystitis, and thrombophlebitis. We described radiologic findings of various organ involvement of SLE; digestive system, serosa, reticuloendothelial system, urinary system, and venous system. Diagnosis of SLE was done according to the criteria of American Rheumatism Association. Understanding of the variable imaging findings in SLE may be helpful for the early detection of abdominal involvement and complications.

  4. Two-cavity gyroklystron with self-excited input cavity

    Sokolov, E.V.; Zasypkin, E.V. [Inst. of Applied Physics, Novgorod (Russian Federation)

    1995-12-31

    A new type of gyro-oscillator-two cavity gyroklystron with self-excited input cavity (or, for simplicity, two-cavity gyrokylstron oscillator) is proposed. In this device, the autooscillations excited in the first cavity modulate electrons by energy, electrons are bunched in the drift space, and then the bunches excite powerful oscillations in the second (output) cavity. Since, as in gyroklystron, the optimal second cavity length L{sub 2} does not exceed 2-2.5 {lambda} ({lambda} is the operating wavelength), its Q-factor Q{sub 2} {approximately} (L{sub 2}/{lambda}){sup 2} should be essentially lower than cavity Q-factor of a traditional gyrotron. It allows to diminish the RF ohmic losses in the second cavity and to enhance the output power without the efficiency reduction. A simplest theory of such oscillator has been developed. Predicted by theory, the output power enhancement (in comparison with that for an ordinary gyrotron) has been demonstrated experimentally.

    Full Text Available In case of three-dimensional visualization the choice ofparacentetic trajectory for access to organs and neoplasms of abdominalcavityand retroperitoneal area can be improved in a great degree. Three-dimensional visualization ofparacentetic trajectory and nearly located large vessels is one of the most important advantages of similar way of representation of diagnostic data. In mostcases three-dimensional representation of diagnostic data allows to choose notonlysafe, but also much shorter paracentetic trajectory.

  6. Parenteral nutrition in experimental acute radiation injury of the abdominal cavity organs

    The peculiarities of metabolism in rats after partial body irradiation of the abdomen in a high dose and the effect of parenteral nutrition (PN) with various compositions of diagrams on metabolic indexes with the aim of explaining diagram under conditions of intensive radiation injury of gastrointestinal tract, are investigated. Experiments have been carried out on male rats of the Vistar line, subjected to partial-body X-ray irradiation of the abdomen with the dose of 1400 R. It is shown that under conditions of radiation effect with predominnt unjury of the abdomen, considerable suppression of oxidation processes limits metabolism of nutritious substances. A decrease of glucose and amino acid content in PN produces a pronounced therapeutic effect under these conditions. The increase of lipid component in the PN composition and retabolile introduction increases PN therapeutic effect

  7. Angiography in differential diagnosis of volumetric formations of the left half of the abdominal cavity

    Results of angiographic studies made in 52 patients with a palpable tumour in the left part of the abdomen having an asymptomatic course were analyzed. A volumetrical process in the left kidney was diagnosed angiographically in 14 patients. An enlarged spleen was seen on the angiograms of 13 patients. A pancreatic cyst was revealed in 10 patients during angiography. When examining patients with tumours of transperitoneal space angiography confirmed the diagnosis in 2 patients. It specified it in 4 patients and appeared ineffective in 4. Angiography revealed tumour of the adrenal gland in 5 patients. Causes of difficulties encountered in making a diagnosis prior to angiography are discussed

    The nominal operating frequency for the HL-LHC crab cavities is 400.79 MHz within a bandwidth of ±60kHz. Attaining the required cavity tune implies a good understanding of all the processes that influence the cavity frequency from the moment when the cavity parts are being fabricated until the cavity is installed and under operation. Different tuning options will be available for the DQW crab cavity of LHC. This paper details the different steps in the cavity fabrication and preparation that may introduce a shift in the cavity frequency and introduces the different tuning methods foreseen to bring the cavity frequency to meet the specifications.

    Imaging of the optical properties of individual nanosystems beyond fluorescence can provide a wealth of information. However, the minute signals for absorption and dispersion are challenging to observe, and only specialized techniques requiring sophisticated noise rejection are available. Here we use signal enhancement in a scanning optical microcavity to demonstrate ultra-sensitive imaging. Harnessing multiple interactions of probe light with a sample within an optical resonator, we achieve a 1700-fold signal enhancement compared to diffraction-limited microscopy. We demonstrate quantitative imaging of the extinction cross section of gold nanoparticles with a sensitivity below 1 nm2, we show a method to improve spatial resolution potentially below the diffraction limit by using higher order cavity modes, and we present measurements of the birefringence and extinction contrast of gold nanorods. The demonstrated simultaneous enhancement of absorptive and dispersive signals promises intriguing potential for opt...

  11. The utility of ultrasonography in the the diagnostics and monitoring of treatment of acute abdominal pain in children with neoplasms

    The aim of this study was to estimate the results of the diagnostic imaging modalities, especially ultrasonography (US) in children during the oncological therapy with the acute abdominal symptoms. Acute abdominal symptoms in children with neoplasms causing a very difficult clinical and diagnostic problems and can occur in any stage of disease. The high-resolution ultrasound has a very important role in diagnosis in all patients with acute abdominal pain and with neoplasms. The authors consider that the US should be the first imaging method in the differential diagnosis of the abdominal changes in children with neutropenia and oncological disease. Proper diagnosis should be established only with clinical information. We analyzed 249 ultrasounds examinations of the abdominal cavity in 144 girls and 105 boys aged from 1 to 18 years (mean age 10, 3 years). The more important indication for the US exam in 133 cases was acute abdominal symptoms. We took exams during pre- and postoperative chemotherapy, radiotherapy and after the hematopoietic stem cell transplantation. All the patients were under routine hematological control. Based on the clinical symptoms and the laboratory tests we analysed two groups of children with oncological disease and acute abdomen: I group - 111 children with neutropenia, II group - 22 children without neutropenia. In the patients who underwent operation procedure the final diagnosis was established on histopathology. In the other cases diagnosis was based on clinical, laboratory and radiological exams, especially ultrasonography. We analyzed clinical picture of disease, the results of therapy and the US changes in examined patients using statistic parameters as: sensitivity, specificity and efficiency. In the group of 133 children with acute abdominal symptoms the most (92- 69,1%) patients suffer from ALL (acute lymphoblastic leukaemia) and 16(12%) - from AML (acute lymphoblastic leukaemia), Ewing sarcoma-3(2,2%), osteosarcoma - 3(2,2%), NHL

    The feature of superconducting rf cavities is an extremely small surface resistance on the wall. It brings a large energy saving in the operation, even those are cooled with liquid helium. That also makes possible to operate themselves in a higher field gradient comparing to normal conducting cavities, and brings to make accelerators compact. These merits are very important for the future accelerator engineering which is planed at JAERI for the neutron material science and nuclear waste transmutation. This machine is a high intensity proton linac and uses sc cavities in the medium and high {beta} sections. In this paper, starting R and D of proton superconducting cavities, several important technical points which come from the small surface resistance of sc cavities, are present to succeed it and also differences between the medium and high - {beta} structures are discussed.

    The mechanical stability of bulk Nb cavity is an important aspect to be considered in relation to cavity material, geometry and treatments. Mechanical properties of Nb are typically obtained from uniaxial tensile tests of small samples. In this contribution we report the results of measurements of the resonant frequency and local strain along the contour of single-cell cavities made of ingot and fine-grain Nb of different purity subjected to increasing uniform differential pressure, up to 6 atm. Measurements have been done on cavities subjected to different heat treatments. Good agreement between finite element analysis simulations and experimental data in the elastic regime was obtained with a single set of values of Young’s modulus and Poisson’s ratio. The experimental results indicate that the yield strength of medium-purity ingot Nb cavities is higher than that of fine-grain, high-purity Nb.

    The aim of this study was to describe the CT features of abdominal plasma cell neoplasms. We reviewed CT imaging findings in 11 patients (seven men, four women; mean age 62 years) with plasma cell neoplasms and abdominal involvement. Helical CT of the entire abdomen and pelvis was performed following intravenous administration of contrast material. Images were analyzed in consensus by two radiologists. Diagnoses were made from biopsy, surgery and/or clinical follow-up findings. Multiple myeloma was found in seven patients and extramedullary plasmacytoma in four patients. All patients with multiple myeloma had multifocal disease with involvement of perirenal space (4/7), retroperitoneal and pelvic lymph nodes (3/7), peritoneum (3/7), liver (2/7), subcutaneous tissues (2/7) and kidney (1/7). In three of the four patients with extramedullary plasmacytoma, a single site was involved, namely stomach, vagina and retroperitoneum. In the fourth patient, a double site of abdominal involvement was observed with rectal and jejunal masses. Plasma cell neoplasm should be considered in the differential diagnosis of single or multiple enhancing masses in the abdomen or pelvis. Abdominal plasma cell neoplasms were most frequently seen as well-defined enhancing masses (10/11). (orig.)

  9. Evaluation of abdominal CT in the initial treatment of abdominal trauma

    During the last four years 102 patients with abdominal trauma were examined by CT for preoperative evaluation in our hospital. In 35 patients (34 %), the CT scans revealed no abnormal findings. They were all managed conservatively except for one case of perforated small bowel. In 67 patients (66 %) CT revealed evidences of substantial abdominal or retroperitoneal trauma. In 30 of them CT findings were confirmed by surgery. Hepatic injury is usually easily recognized by CT. CT is also useful for the detection of renal or splenic injuries. The majority of those parenchymatous organ injuries were successfully managed with conservative therapy, despite apparent traumatic lesions revealed by CT. Repeat CT scans is proved to be very useful to follow the changes of these traumatic lesions. In conclusion, application of abdominal CT is extremely useful for the initial decision making in treatment of patients with abdominal trauma and for the follow-up observation of injured lesions.

    Intra-abdominal hypertension (IAH) is accompanied by high morbidity and mortality in surgical departments and ICUs. However, its specific pathophysiology is unclear. IAH not only leads to intra-abdominal tissue damage but also causes dysfunction in distal organs, such as the brain. In this study, we explore the protective effects of melanocortin 4 receptor agonists in IAH-induced brain injury. The IAH rat models were induced by hemorrhagic shock/resuscitation (with the mean arterial pressure (MAP) maintained at 30 mm Hg for 90 min followed by the reinfusion of the withdrawn blood with lactated Ringer's solution). Then, air was injected into the peritoneal cavity of the rats to maintain an intra-abdominal pressure of 20 mm Hg for 4 h. The effects of the melanocortin 4 receptor agonist RO27-3225 in alleviating the rats' IAH brain injuries were observed, which indicated that RO27-3225 could reduce brain edema, the expressions of the IL-1β and TNF-α inflammatory cytokines, the blood-brain barrier's permeability and the aquaporin4 (AQP4) and matrix metalloproteinase 9 (MMP9) levels. Moreover, the nicotinic acetylcholine receptor antagonist chlorisondamine and the selective melanocortin 4 receptor antagonist HS024 can negate the protective effects of the RO27-3225. The MC4R agonist can effectively reduce the intracerebral proinflammatory cytokine gene expression and alleviate the brain injury caused by blood-brain barrier damage following IAH. PMID:25616531

    Intra-abdominal pressure (IAP) and abdominal perfusion pressure (APP) have shown clinical relevance in monitoring critically ill human beings submitted to abdominal surgery. Only a few studies have been performed in veterinary medicine. The aim of this study was to assess how pregnancy and abdominal surgery may affect IAP and APP in healthy cats. For this purpose, pregnant (n=10) and non-pregnant (n=11) queens undergoing elective spaying, and tomcats (n=20, used as controls) presented for neutering by scrotal orchidectomy were included in the study. IAP, mean arterial blood pressure (MAP), APP, heart rate and rectal temperature (RT) were determined before, immediately after, and four hours after surgery. IAP increased significantly immediately after abdominal surgery in both female groups when compared with baseline (P<0.05) and male (P<0.05) values, and returned to initial perioperative readings four hours after surgery. Tomcats and pregnant females (P<0.05) showed an increase in MAP and APP immediately after surgery decreasing back to initial perioperative values four hours later. A significant decrease in RT was appreciated immediately after laparotomy in both pregnant and non-pregnant queens. IAP was affected by abdominal surgery in this study, due likely to factors, such as postoperative pain and hypothermia. Pregnancy did not seem to affect IAP in this population of cats, possibly due to subjects being in early stages of pregnancy. PMID:23118052

  17. Salmonellosis mimicking abdominal lymphoma in a young boy

    We report on a child with intra-abdominal lymphadenopathy and hepatosplenomegaly due to salmonellosis, whose initial diagnosis was erroneously based on computed tomography (CT) findings suggestive of abdominal lymphoma. Awareness that salmonellosis can produce large abdominal masses should assist in ruling out neoplastic disease in the differential diagnosis, thus avoiding unnecessary laparotomy. (orig.)

    2013-01-01

    Only 50% of abdominal aortic aneurysms present with the classic triad of hypotension, back pain and a pulsatile abdominal mass. This variability in symptoms can delay diagnosis and treatment. We present the case of a patient presenting with a unique combination of symptoms suggesting that decompression of urinary retention can lead to abdominal aortic aneurysm rupture. PMID:24964430

  3. Frequency-feedback cavity enhanced spectrometer

    Hovde, David Christian; Gomez, Anthony

    2015-08-18

    A spectrometer comprising an optical cavity, a light source capable of producing light at one or more wavelengths transmitted by the cavity and with the light directed at the cavity, a detector and optics positioned to collect light transmitted by the cavity, feedback electronics causing oscillation of amplitude of the optical signal on the detector at a frequency that depends on cavity losses, and a sensor measuring the oscillation frequency to determine the cavity losses.

  4. Cavity beam position monitors

    Beam-based alignment and feedback systems are essential for the operation of future linear colliders and free electron lasers. A certain number of beam position monitors with a resolution in the submicron range are needed at selected locations. Most beam position monitors detect the electric or the magnetic field excited by a beam of charged particles at different locations around the beam pipe. In resonant monitors, however, the excitation of special field configurations by an off-center beam is detected. These structures offer a large signal per micron displacement. This paper is an attempt to summarize the fundamental characteristics of resonant monitors, their advantages and shortcomings. Emphasis will be on the design of cylindrical cavities, in particular on the estimation of expected signals, of resolution limits and the resulting beam distortion. This includes also a short introduction into numerical methods. Fabrication, tuning, and other practical problems will be reviewed briefly. Finally, some resonant devices used for beam position diagnostics will be discussed and listed

  5. Three-dimensional cavity calculations

    The existence of a code that solves for the resonant electromagnetic modes of oscillation in arbitrarily-shaped three-dimensional cavities opens new possibilities in rf-structure analysis and research. The URMEL-3D code, the product of a multi-year collaboration between DESY, KFA-Juelich, and Los Alamos, has been used in some exploratory studies to determine the feasibility of using a 3-D code to calculate the properties of several practical rf structures. The results are reported here for three cases: the jungle gym, two coupled cavities, and a waveguide-cavity coupling problem

  6. Beam - cavity interaction beam loading

    The interaction of a beam with a cavity and a generator in cyclic accelerators or storage rings is investigated. Application of Maxwell's equations together with the nonuniform boundary condition allows one to get an equivalent circuit for a beam-loaded cavity. The general equation for beam loading is obtained on the basis of the equivalent circuit, and the beam admittance is calculated. Formulas for power consumption by a beam-loaded cavity are derived, and the optimal tuning and coupling factor are analyzed. (author)

  7. Focused abdominal sonography for trauma (FAST) in blunt paediatric abdominal trauma

    Objective: To evaluate the role of focussed abdominal sonography for trauma in blunt paediatric abdominal trauma patients, and to see if the role of computed tomography scan could be limited to only those cases in which sonography was positive. Methods: The retrospective study covered 10 years, from January 1, 2000 to December 31, 2009, and was conducted at the Department of Radiology and Department of Emergency Medicine, Aga Khan University Hospital, Karachi. It comprised cases of 174 children from birth to 14 years who had presented with blunt abdominal trauma and had focussed abdominal sonography for trauma done at the hospital. The findings were correlated with computed tomography scan of the abdomen and clinical follow-up. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of focussed abdominal sonography for trauma were calculated for blunt abdominal trauma. SPSS 17 was used for statistical analysis. Results: Of the total 174 cases, 31 (17.81%) were later confirmed by abdominal scan. Of these 31 children, sonography had been positive in 29 (93.54%) children. In 21 (67.74%) of the 31 children, sonography had been true positive; 8 (25%) (8/31) were false positive; and 2 (6%) (2/31) were false negative. There were 6 (19.3%) children in which sonography was positive and converted to laparotomy. There was no significant difference on account of gender (p>0.356). Focussed abdominal sonography for trauma in the study had sensitivity of 91%, specificity of 95%, positive predictive value of 73%, and negative predictive value of 73% with accuracy of 94%. All patients who had negative sonography were discharged later, and had no complication on clinical follow-up. Conclusions: Focussed abdominal sonography for trauma is a fairly reliable mode to assess blunt abdominal trauma in children. It is a useful tool to pick high-grade solid and hollow viscous injury. The results suggest that the role of computed tomography scan can be

  8. Transferring a cavity field entangled state in cavity QED

    Ye Liu [Anhui Key Laboratory of Information Material and Devices, School of Physics and Material Science, Anhui University, Hefei 230039 (China); Guo Guangcan [Key Laboratory of Quantum Information, University of Science and Technology of China, Chinese Academy of Sciences, Hefei 230026 (China)

    2005-08-01

    We propose a scheme for transferring an entanglement of zero- and one-photon states from one cavity to another. The scheme, which has 100% success probability, is mainly based on a two-mode cavity dispersively interacting with a three-level atom in the {lambda} configuration and does not involve Bell-state measurement. This scheme can also be used to teleport an unknown atomic state.

  9. Reducing Abdominal Fat Deposition in Broiler Through Feeding Management

    Cecep Hidayat

    2015-09-01

    Full Text Available Abdominal fat in broiler carcass is considered as a waste and its existence reduces the carcass quality. Abdominal fat deposition is affected by several factors such as genetic, nutrition, feed, sex, age and environment. Reducing abdominal fat deposition can be carried out by regulating the nutrient intake to ensure that no excessive nutrient was consumed. Nutrition effects to reduce abdominal fat deposition are associated with nutrient concentration of ration and quantity of daily feed intake. Daily nutrient intake can be limited, especially through restricted feeding. It is concluded that an appropriate feeding management can reduce abdominal fat deposition in broiler.

  10. Handlebar Hernia: A Rare Type of Abdominal Wall Hernia

    Rooh-Allah Yegane

    2010-10-01

    Full Text Available Traumatic abdominal wall hernias are a type of acquired hernia secondary to blunt trauma Caused, by direct trauma from handlebar like objects. This rare hernia is named ‘Handlebar hernia'. We report a case of such hernia without any significant intra-abdominal injury. The abdominal wall defect was repaired in layers by Jones technique. Postoperative course was uneventful. The authors recommend clinical suspicion for traumatic hernia in all patients with traumatic abdominal wall injury. Definitive treatment includes surgical exploration with primary repair of all tissue layers of the abdominal wall.

    The primo vascular system (PVS) is being established as a circulatory system that corresponds to acupuncture meridians. There have been two critical questions in making the PVS accepted as a novel liquid flowing system. The first one was directly to show the flow of liquid in PVS and the second one was to explain why it was not observed in the conventional histological study of animal tissues. Flow in the PVS in the abdominal cavity was previously verified by injecting Alcian blue into a primo node. However, the tracing of the dye to other subsystems of the PVS has not been done. In the current work we injected fluorescent nanoparticles (FNPs) into a primo node and traced them along a primo vessel which was inside a fat tissue in the abdominal wall. Linea alba is a white middle line in the abdominal skin of a mammal and a band of fat tissue is located in parallel to the linea alba in the parietal side of the abdominal wall of a rat. In this fat band a primo vessel runs parallel to the prominent blood vessels in the fat band and is located just inside the parietal peritoneum. About the second question on the reason why the PVS was not in conventional histological study the current work provided the answer. Histological analysis with hematoxyline and eosine, Masson's trichrome, and Toluidine blue could not discriminate the primo vessel even when we knew the location of the PVS by the trace of the FNPs. This clearly explains why the PVS is hard to observe in conventional histology: it is not a matter of resolution but the contrast. The PVS has very similar structure to the connective tissues that surround the PVS. In the current work we propose a method to find the PVS: Observation of mast cell distribution with toluidine blue staining and the PN has a high density of mast cells, while the lymph node has low density.

    Background Chylous ascites is the pathologic leakage of triglycerides-rich lymphatic fluid into the peritoneal cavity. Chylous ascites is a rare complication in abdominal surgery. This study aimed to find a relatively better method for nutrition support in the treatment of chylous ascites after abdominal surgery. Methods This study was a retrospective study. This study retrospectively reviewed patients who underwent abdominal surgery and developed chylous ascites, from the year 2010 to 2014, at the West China Hospital of Sichuan University and the Affiliated Hospital of Zunyi Medical College. Fifty-eight patients who developed chylous ascites after abdominal surgery were included in the study. The clinical effect of somatostatin was evaluated. The differences in the curative efficacy among a daily diet, a low-fat diet supplemented with medium-chain triglyceride (MCT), and total parenteral nutrition (TPN) were also analyzed in this study. Results Complete clinical success was reached earlier in patients treated with somatostatin (P<0.001). The tube removal time, the time to resumption of an oral diet, and the length of hospital stay after chylous leakage were significantly different between patients treated with and without somatostatin. The curative efficacies of the enteral nutrition (EN) + MCT plan and the TPN plan were quite similar, with no significant difference, however, were significantly different from the MCT regime, which was the worst. However, using the EN + MCT plan was more cost-effective (P=0.038). Conclusion In treating chylous ascites, EN + MCT instead of TPN was the best nutrition support. Moreover, somatostatin or its analog octreotide should be used immediately. The treatment with somatostatin in combination with EN + MCT is recommended in the conservative treatment of postoperative chylous ascites. PMID:27143902

  14. Transversus abdominal plane (TAP block for postoperative pain management: a review [version 1; referees: 2 approved

    Jan Jakobsson

    2015-11-01

    Full Text Available Transversus abdominal plane (TAP block has a long history and there is currently extensive clinical experience around TAP blocks. The aim of this review is to provide a summary of the present evidence on the effects of TAP block and to provide suggestions for further studies. There are several approaches to performing abdominal wall blocks, with the rapid implementation of ultrasound-guided technique facilitating a major difference in TAP block performance. During surgery, an abdominal wall block may also be applied by the surgeon from inside the abdominal cavity. Today, there are more than 11 meta-analyses providing a compiled evidence base around the effects of TAP block. These analyses include different procedures, different techniques of TAP block administration and, importantly, they compare the TAP block with a variety of alternative analgesic regimes. The effects of TAP block during laparoscopic cholecystectomy seem to be equivalent to local infiltration analgesia and also seem to be beneficial during laparoscopic colon resection. The effects of TAP are more pronounced when it is provided prior to surgery and these effects are local anaesthesia dose-dependent. TAP block seems an interesting alternative in patients with, for example, severe obesity where epidural or spinal anaesthesia/analgesia is technically difficult and/or poses a risk. There is an obvious need for further high-quality studies comparing TAP block prior to surgery with local infiltration analgesia, single-shot spinal analgesia, and epidural analgesia. These studies should be procedure-specific and the effects should be evaluated, both regarding short-term pain and analgesic requirement and also including the effects on postoperative nausea and vomiting, recovery of bowel function, ambulation, discharge, and protracted recovery outcomes (assessed by e.g., postoperative quality of recovery scale.

  15. Diagnostic imaging of infantile abdominal cystic disease

    Thirty-seven patients with infantile abdominal cystic disorders were studied by ultrasound (US), computed tomography (CT), or magnetic resonance imaging (MRI). US studies are simple to conduct, and commonly show an echo-free mass, but tend to yield hyperechoic images when fat and blood are present in the cystic fluid. CT studies, which distinctly demonstrate water, fat, soft tissue density and calcification, are very helpful in the diagnosis of cystic tumor, especially cystic teratoma. MR imaging, which is capable of distinguishing the nature of the cystic fluid (e.g., serous, chylous, bloody, fatty, etc.), is useful in the diagnosis of lymphangioma, teratoma, and torsion of ovarian cystic tumor. Based on the results of the present study, US may be considered to be the modality of first choice in the examination of infantile abdominal cystic disorders, and MRI and/or CT should be employed additionally as necessary in that order.

  16. Drug Therapy for Small Abdominal Aortic Aneurysm

    Ramachandran Meenakshisundaram

    2010-03-01

    Full Text Available Abdominal aortic aneurysm is often asymptomatic, less recognized, and causes considerable mortalityand morbidity, if missed. The incidence varies from country to country and the occurrence is influencedby modifiable (smoking, coronary heart disease, hypertension, dyslipidemia, and prolonged steroid therapyand non-modifiable risk factors (increasing age, male gender, and positive family history. Most ofthe patients with such aneurysm do not exhibit symptoms and the diagnosis is made accidentally duringroutine medical investigations, abdominal ultrasonography, or by an astute surgeon during an abdominalprocedure. Sometimes the diagnosis is made in an emergency room, if the attending resident/doctor isaware of it. Despite good diagnosis and effective management, the outcomes of complicated cases arepoor and the treatment cost is prohibitive. Hence, we reviewed the literature to find out the pathogenesisof such aneurysms and the usefulness of available drugs in its prevention.

  17. Evidence-based diagnosis of abdominal trauma

    Abdominal trauma is a common cause of death particularly in patients up to 40 years of age. In order to reduce mortality a rapid radiologic diagnosis is essential. At present, sonography plays a role only in the evaluation of minor trauma and as a ''focused assessment with sonography for trauma'' (FAST) to clarify free intraperitoneal fluid immediately on admittance in severely injured patients. However, computed tomography has proven to be a potent tool for the triage of patients with abdominal trauma, because, based on the results of the CT scan, patients can be referred for laparotomy or safely classified for ''wait and see'' treatment. Therapeutic decisions are largely based on injury severity scores and the radiologist must be familiar with them as well as with the associated therapeutic consequences. (orig.)

  18. Abdominal pregnancy as a cause of hemoperitoneum

    Shafi Sheikh

    2009-01-01

    Full Text Available The coexistence of intrauterine and extrauterine pregnancy, the heterotopic pregnancy, is a rare obstetric phenomenon. The preoperative diagnosis of this condition is very difficult; leading to a higher maternal morbidity and fetal loss. We experienced a case of intrauterine pregnancy and ruptured abdominal pregnancy implanted on the illeocaecal region in a 26-year-old primiparous woman. She was clinically misdiagnosed as a case of ruptured ectopic pregnancy, but ultrasonography showed it to be a case of heterotopic pregnancy. Subsequently, the patient was subjected to laparotomy and the ruptured abdominal pregnancy was evacuated. She continued with the intrauterine pregnancy till term and delivered a healthy female baby. Although this condition is unusual, any general surgeon in the emergency department must be aware of this complication and its management, which is often initially misdiagnosed.

  19. SRF Cavity Fabrication and Materials

    Singer, W

    2014-01-01

    The technological and metallurgical requirements of material for highgradient superconducting cavities are described. High-purity niobium, as the preferred metal for the fabrication of superconducting accelerating cavities, should meet exact specifications. The content of interstitial impurities such as oxygen, nitrogen, and carbon must be below 10μg/g. The hydrogen content should be kept below 2μg/g to prevent degradation of the Q-value under certain cool-down conditions. The material should be free of flaws (foreign material inclusions or cracks and laminations) that can initiate a thermal breakdown. Defects may be detected by quality control methods such as eddy current scanning and identified by a number of special methods. Conventional and alternative cavity fabrication methods are reviewed. Conventionally, niobium cavities are fabricated from sheet niobium by the formation of half-cells by deep drawing, followed by trim machining and Electron-Beam Welding (EBW). The welding of half-cells is a delicate...

  20. Niobium LEP 2 accelerating cavities

    An accelerating cavity from LEP. This could be cut open to show the layer of niobium on the inside. Operating at 4.2 degrees above absolute zero, the niobium is superconducting and carries an accelerating field of 6 million volts per metre with negligible losses. Each cavity has a surface of 6 m2. The niobium layer is only 1.2 microns thick, ten times thinner than a hair. Such a large area had never been coated to such a high accuracy. A speck of dust could ruin the performance of the whole cavity so the work had to be done in an extremely clean environment. These challenging requirements pushed European industry to new achievements. 256 of these cavities were used in an upgrade of the LEP accelerator to double the energy of the particle beams.

  1. Geometry-Invariant Resonant Cavities

    Liberal, Iñigo; Engheta, Nader

    2015-01-01

    Resonant cavities are one of the basic building blocks in various disciplines of science and technology, with numerous applications ranging from abstract theoretical modeling to everyday life devices. The eigenfrequencies of conventional cavities are a function of its geometry, and, thus, the size and shape of a resonant cavity is selected in order to operate at a specific frequency. Here, we demonstrate theoretically the existence of geometry-invariant resonant cavities, i.e., resonators whose eigenfrequency is invariant with respect to geometrical deformations. This effect is obtained by exploiting the unusual properties of zero-index metamaterials, which enable decoupling of the time and spatial field variations. This new class of resonators may inspire alternative design concepts, and it might lead to the first generation of deformable resonant devices.

  2. CRAB Cavity in CERN SPS

    Beam collisions with a crossing angle at the interaction point are often necessary in colliders to reduce the effects of parasitic collisions which induce emittance growth and decrease beam lifetime. The crossing angle reduces the geometrical overlap of the beams and hence the luminosity. Crab cavity offer a promising way to compensate the crossing angle and to realize effective head-on collisions. Moreover, the crab crossing mitigates the synchro-betatron resonances due to the crossing angle. A crab cavity experiment in SPS is proposed as a proof of principle before deciding on a full crab-cavity implementation in the LHC. In this paper, we investigate the effects of a single crab cavity on beam dynamics in the SPS and life time.

    Analysis of the surgical criteria for reintervention in Abdominal Surgery led to the accentuation of a certain number of pictures of occlusion, general infectious syndromes, postoperative peritonitis, gastro-intestinal fistula and hemorrhagic syndrome. In all cases, the clinical examination can be misleading in particular in the case of peritonitis, and the history and non-surgical criteria must be strongly borne in mind. PMID:2036

    We describe here a case of abdominal abscesses due to Mycobacterium fortuitum following liposuction. The abscesses developed three months after the procedure and diagnosis was delayed for five months. The clues for diagnosis were persistent pus discharge in spite of broad spectrum antibiotics and failure to grow any organisms on routine culture. This condition has been rarely reported; however, the increasing number of liposuction procedures done and awareness among physicians will probably r...

  5. Computed tomography of pediatric abdominal masses

    Ultrasonography is a very useful diagnostic modality for evaluation of the pediatric abdominal masses, due to faster, cheaper, and no radiation hazard than CT. But CT has more advantages in assessing precise anatomic location, and extent of the pathologic process, and also has particular value in defining the size, relation of the mass to surrounding organs and detection of lymphadenopathy. We analyzed CT features of 35 cases of pathologically proven pediatric abdominal masses for recent 2 years at Ewha Woman's University Hospital. The results were as follows: 1.The most common originating site was kidney (20 cases, 57.1%); followed by gastrointestinal (5 cases, 14.3%), nonrenal retroperitoneal (4 cases, 11.4%), hepatobiliary (3 cases, 8.6%), and genital (3 cases, 8.6%) in order of frequency. 2.The most common mass was hydronephrosis (11 cases, 31.4%), Wilms' tumor (7 cases, 20.0%), neuroblastoma, choledochal cyst, periappendiceal abscess (3 cases, 8.6%, respectively), ovarian cyst (2 cases, 5.7%) were next in order of frequency. 3.Male to female ratio was 4:5 and choledochal cyst and ovarian cyst were found only in females. The most prevalent age group was 1-3 year old (12 cases, 34.3%). 4.With CT, the diagnosis of hydronephrosis was easy in all cases and could evaluate of its severity, renal function and obstruction site with high accuracy. 5.Wilms' tumor and neuroblastoma were relatively well differentiated by their characteristic CT features; such as location, shape, margin, middle cross, calyceal appearance and calcification, etc. 6.Ovarian and mensentric cysts had similar CT appearance. 7.In other pediatric abdominal masses, CT provided excellent information about anatomic detail, precise extent of tumor and differential diagnostic findings. So, CT is useful imaging modality for the demonstration and diagnosis of abdominal mass lesions in pediatric patients

  6. Laparoscopic biopsy in patients with abdominal lymphadenopathy

    Bhandarkar D

    2007-01-01

    Full Text Available Background: Abdominal lymphadenopathy (AL - a common clinical scenario faced by clinicians - often poses a diagnostic challenge. In the absence of palpable peripheral nodes, tissue has to be obtained from the abdominal nodes by image-guided biopsy or surgery. In this context a laparoscopic biopsy avoids the morbidity of a laparotomy. Aim: This retrospective analysis of prospectively collected data represents our experience with laparoscopic biopsy of abdominal lymph nodes. Materials and Methods: Between October 2000 and November 2005, 28 patients with AL underwent laparoscopic biopsy. Pre-operative radiological imaging studies had identified a nodal mass in 20, a solitary node in 1, a cold abscess in 1 and a mesenteric cystic lesion in 1 patient. In five patients with chronic right lower abdominal pain and normal ultra-sonographic findings mesenteric nodes were identified and biopsied during diagnostic laparoscopy. Results: The sites of biopsied lymph nodes included para-aortic (10, mesenteric (8, external iliac (3, left gastric (2, obturator (1, aorto-caval (1 and porta hepatis (1. One patient with enlarged peripancreatic nodes mass and another with a mesenteric cystic mass had cold abscesses drained in addition to biopsy. There were no perioperative complications and the median postoperative stay was 2 days (range 1-4 days. Histopathology revealed tuberculosis in 23 patients, reactive adenitis in 2, lymphoma in 1 metastatic carcinoma in 1, and a retroperitoneal sarcoma in 1. Conclusions: In patients with AL, laparoscopy provides a safe and effective means of obtaining biopsy. It is of particular value in patients in whom (a the nodes are small or present in locations unsuitable for image-guided biopsy, (b adequate tissue cannot be obtained by image-guided biopsy or (c previously undiagnosed lymphadenopathy is encountered during diagnostic laparoscopy.

  8. Dose reduction in abdominal computed tomography

    The broad availability and use of multidetector computed tomography (MDCT) in recent years has increased the radiation dose for patients. Multiphase MDCT protocols are used in abdominal imaging for various indications. Dose reduction though novel technologies, such as dual energy CT or adapted contrast injection protocols (split bolus etc.) for reduction of scans. An optimized dose reduction can be achieved by using strict protocols which are adapted to the clinical situation of the patient. (orig.)

    Spontaneous sac size regression of a giant abdominal aortic aneurysm (AAA) is a rare event that has not been previously described. We report a case of an 89-year-old woman with a known 9-cm AAA, which was diagnosed in 2003. The patient had refused any kind of treatment at that time. Recent imaging studies obtained 7 years later revealed an AAA of 4 cm diameter. This is the first recorded case of significant spontaneous AAA sac shrinkage. PMID:21444348

  10. Malignant peritoneal mesothelioma after remote abdominal radiation

    Peritoneal mesothelioma in a 61-year-old man, occurred 26 years after abdominal radiotherapy for a testicular seminoma. The patient had no history of asbestos exposure. After asbestos, radiation is the second most frequent defined cause of mesothelioma in North America, but the number of well-documented cases is small; this case represents only the fifth example of peritoneal mesothelioma after therapeutic irradiation of the abdomen. 16 references

    2009-01-01

    The coexistence of intrauterine and extrauterine pregnancy, the heterotopic pregnancy, is a rare obstetric phenomenon. The preoperative diagnosis of this condition is very difficult; leading to a higher maternal morbidity and fetal loss. We experienced a case of intrauterine pregnancy and ruptured abdominal pregnancy implanted on the illeocaecal region in a 26-year-old primiparous woman. She was clinically misdiagnosed as a case of ruptured ectopic pregnancy, but ultrasonography showed it to ...

  12. Child abdominal tumour in tropical context: Think about schistosomiasis!

    A. M. Napon

    2014-01-01

    Full Text Available Schistosomiasis presenting as an abdominal mass with chronic pain in a child is not common. This report presents case of child presenting with schistosomiasis presenting as an abdominal mass with chronic pain. Abdominal ultrasonography did not particularly contribute to definitive pre-operative diagnosis. However, pathological examination of surgical specimen confirmed Schistosoma mansoni eggs in the biospy. A decrease in the mass volume was noticed under medical treatment (Biltricide. The aim of this report was to intimate clinicians on possible abdominal schistosomiasis as differential diagnosis of childhood abdominal mass. This is a clarion call for a high index of suspicion of childhood abdominal schistosomiasis in children presenting with abdominal mass in a tropical setting.

  13. LEP Radio Frequency Copper Cavities

    The pulse of a particle accelerator. 128 of these radio frequency cavities were positioned around CERN's 27-kilometre LEP ring to accelerate electrons and positrons. The acceleration was produced by microwave electric oscillations at 352 MHz. The electrons and positrons were grouped into bunches, like beads on a string, and the copper sphere at the top stored the microwave energy between the passage of individual bunches. This made for valuable energy savings as it reduced the heat generated in the cavity.

    2008-01-01

    AIM: To estimate the prevalence of inherited and acquired thrombophilic risk factors in patients with abdominal venous thrombosis and to compare the risk factor profiles between Budd-Chiari syndromes (BCS) and splanchnic vein thrombosis (SVT).METHODS: In this retrospective study, 36 patients with abdominal venous thrombosis were studied.The patients were divided into Budd-Chiari group (hepatic vein, IVC thrombosis) and splanchnic venous thrombosis group (portal, splenic, superior mesenteric veins) based on the veins involved. Hereditary and acquired thrombophilic risk factors were evaluated in all patients.RESULTS: Twenty patients had SVT, 14 had BCS,and 2 had mixed venous thrombosis. Ten patients (28%) had hereditary and 10 patients (28%) acquired thrombophilic risk factors. The acquired risk factors were significantly more common in the SVT group (SVT vs BCS:45% vs 7%,x2=5.7,P=0.02) while hereditary risk factors did not show significant differences between the two groups (SVT vs BCS: 25%vs 36%, x2=0.46,P=0.7). Multiple risk factors were present in one (7%) patient with BCS and in 3 patients (15%) with SVT. No risk factors were identified in 57% of patients with BCS and in 45% of patients with SVT.CONCLUSION: Hereditary and acquired risk factors play an important role in the etiopathogenesis of abdominal venous thrombosis. Acquired risk factors are significantly more common in SVT patients while hereditary factors are similar in both groups.

  17. Sagittal Abdominal Diameter: Application in Clinical Practice

    Thaís Da Silva-Ferreira

    2014-05-01

    Full Text Available Excess visceral fat is associated with cardiovascular risk factors. Sagittal abdominal diameter (SAD has recently been highlighted as an indicator of abdominal obesity, and also may be useful in predicting cardiovascular risk. The purpose of the present study was to review the scientific literature on the use of SAD in adult nutritional assessment. A search was conducted for scientific articles in the following electronic databases: SciELO , MEDLINE (PubMed and Virtual Health Library. SAD is more associated with abdominal fat (especially visceral, and with different cardiovascular risk factors, such as, insulin resistance, blood pressure, and serum lipoproteins than the traditional methods of estimating adiposity, such as body mass index and waist-to-hip ratio. SAD can also be used in association with other anthropometric measures. There are still no cut-off limits established to classify SAD as yet. SAD can be an alternative measure to estimate visceral adiposity. However, the few studies on this diameter, and the lack of consensus on the anatomical site to measure SAD, are obstacles to establish cut-off limits to classify it.

  18. Midgut malrotation with chronic abdominal pain

    Anil K Wanjari

    2012-01-01

    Full Text Available Abnormalities in midgut rotation occur during the physiological herniation of midgut between the 5 th and 10 th week of gestation. The most significant abnormality is narrow small bowel mesentery which is prone to volvulus. This occurs most frequently in the neonatal period, less commonly midgut malrotation presents in adulthood with either acute volvulus or chronic abdominal symptoms. It is the latter group that represents a diagnostic challenge. We report a case of a 17-year-old male patient who presented with 10-year history of nonspecific gastro-intestinal symptoms. After extensive investigation the patient was diagnosed with midgut malrotation following computed tomography of abdomen. The patient was treated with a laparoscopic Ladd′s procedure and at 3 months he was gaining weight and had stopped vomiting. A laparoscopic Ladd′s procedure is an acceptable alternative to the open technique in treating symptomatic malrotation in adults. Midgut malrotation is a rare congenital anomaly which may present as chronic abdominal pain. Abdominal CT is helpful for diagnosis.

  19. Intra-abdominal hypertension and acute pancreatitis.

    Mifkovic, A; Skultety, J; Sykora, P; Prochotsky, A; Okolicany, R

    2013-01-01

    Intra-abdominal hypertension (IAH) contributes to organ dysfunction and leads to the development of the abdominal compartment syndrome (ACS). IAH and ACS are relatively frequent findings in patiens with severe acute pancreatitis (SAP) and are associated with deterioration in organ functions. The most affected are cardiovascular, respiratory and renal functions. The incidence of IAH in patients with SAP is approximately 60-80%. There is an accumulating evidence in human and animal studies that changes of perfusion, particularly to the microvasculature, are crucial events in the progression of acute pancreatitis (AP). The perfusion of the small and large intestine is impaired due to reduced arterial pressure, increased vascular resistence and diminished portal blood flow. Bacterial translocation has been described in patients with ACS, and this may apply to patients with SAP. Approximately 30-40% of SAP patients develop ACS because of pancreatic (retroperitoneal) inflammation, peripancreatic tissue edema, formation of fluid collections or abdominal distension. Surgical debridement was the preferred treatment to control necrotizing pancreatitis in the past. However, the management of necrotizing pancreatitis has changed over the last decade. The main objective of this article is to describe the association between IAH and AP and to emphasize this situation in clinical praxis as well (Fig. 1, Ref. 38). PMID:23406186

  20. CT of hemodynamically unstable abdominal trauma

    This article is an appraisal of the use of CT in the management of patients with unstable abdominal trauma. We examined 41 patients with abdominal trauma using noncontrast dynamic CT. In 17 patients a postcontrast dynamic CT was also carried out. On CT, 25 patients had hemoperitoneum. Thirteen patients had splenic, 12 hepatic, 6 pancreatic, 8 bowel and mesenteric, 12 renal and 2 vascular injuries. Seven patients had retroperitoneal and 2 patients adrenal hematomas. All but five lesions (three renal, one pancreatic, and one splenic) were hypodense when CT was performed earlier than 8 h following the injury. Postcontrast studies (n = 17), revealed 4 splenic, 3 hepatic, 1 pancreatic, 3 renal, and 2 bowel and mesenteric injuries beyond what was found on noncontrast CT. Surgical confirmation (n = 21) was obtained in 81.81 % of splenic, 66.66 % of hepatic, 83.33 % of pancreatic, 100 % of renal, 100 % of retroperitoneal, and 85.71 % of bowel and mesenteric injuries. The majority of false diagnoses was obtained with noncontrast studies. Computed tomography is a remarkable method for evaluation and management of patients with hemodynamically unstable abdominal trauma, but only if it is revealed in the emergency room. Contrast injection, when it could be done, revealed lesions that were not suspected on initial plain scans. (orig.)

  1. Computed tomography in therapy planning: Abdominal region

    The radiotherapy community is continuing to appreciate the significant contribution CBT can make to planning abdominal radiotherapy and is also beginning to appreciate the pitfalls and limitations of the technique. Specific attention should continue to focus on patient registration with the scanner and simulator radiographs, patient position during scanning and treatment, and effects of involuntary patient motion, especially breathing, on organ and tumor localization. Effects of patient positional changes and of involuntary motion during treatment on treatment planning and execution should be quantitated, as should effects of inhomogeneities, especially gut air, on abdominal dose distribution. Radiotherapy planned with CBT data can impact significantly on morbidity and mortality associated with abdominal malignancies. Faster scanners (with a scanning time of 9 sec or less) should be employed where possible to obtain maximum diagnostic information. Multiplanar reconstruction and true three-dimensional treatment planning can enhance significantly the value of CBT in treatment planning. Radiotherapists, radiodiagnosticians, radiation physicists, and oncologists must be continue to meet the challenge of realizing the true potential of CBT for the benefit of the cancer patients entrusted to their care

  2. Multidetector CT of blunt abdominal trauma.

    Soto, Jorge A; Anderson, Stephan W

    2012-12-01

    The morbidity, mortality, and economic costs resulting from trauma in general, and blunt abdominal trauma in particular, are substantial. The "panscan" (computed tomographic [CT] examination of the head, neck, chest, abdomen, and pelvis) has become an essential element in the early evaluation and decision-making algorithm for hemodynamically stable patients who sustained abdominal trauma. CT has virtually replaced diagnostic peritoneal lavage for the detection of important injuries. Over the past decade, substantial hardware and software developments in CT technology, especially the introduction and refinement of multidetector scanners, have expanded the versatility of CT for examination of the polytrauma patient in multiple facets: higher spatial resolution, faster image acquisition and reconstruction, and improved patient safety (optimization of radiation delivery methods). In this article, the authors review the elements of multidetector CT technique that are currently relevant for evaluating blunt abdominal trauma and describe the most important CT signs of trauma in the various organs. Because conservative nonsurgical therapy is preferred for all but the most severe injuries affecting the solid viscera, the authors emphasize the CT findings that are indications for direct therapeutic intervention.

  3. Dor abdominal aguda como manifestação de violência física em lactente: alerta aos pediatras Dolor abdominal agudo como manifestación de violencia física en lactante: alerta a los pediatras Acute abdominal pain as a manifestation of physical violence in an infant: alert to pediatricians

    Patricia Gomes de Souza

    2012-12-01

    Pediatría y de los pediatras en general para el acercamiento a la violencia contra el niño, para que estén más preparados para accionar la línea de cuidados en situaciones de violencia.OBJECTIVE: To alert pediatricians and pediatric residents on the possibility of child abuse by reporting a clinical case. CASE DESCRIPTION: An 18 month-old infant was brought to the Emergency Department due to abdominal pain and vomiting for 48 hours. Abdominal examination revealed two holes and a small hardened mass. An abdominal X-ray showed three metallic objects. Two sewing needles and one nail without a head were removed from the abdominal cavity by laparotomy. COMMENTS: Diagnosis was performed in the second medical care, probably because the intentional injury had not been considered in the first visit. Physical violence is a differential diagnosis to be considered in the presence of abdominal pain in children. It is worth noting the importance of improving pediatric resident training, and also of pediatricians in general, in relation to the approach of child abuse, enabling them to use adequate care in cases of violence.

  4. Inter-observer agreement for abdominal CT in unselected patients with acute abdominal pain

    The level of inter-observer agreement of abdominal computed tomography (CT) in unselected patients presenting with acute abdominal pain at the Emergency Department (ED) was evaluated. Two hundred consecutive patients with acute abdominal pain were prospectively included. Multi-slice CT was performed in all patients with intravenous contrast medium only. Three radiologists independently read all CT examinations. They recorded specific radiological features and a final diagnosis on a case record form. We calculated the proportion of agreement and kappa values, for overall, urgent and frequently occurring diagnoses. The mean age of the evaluated patients was 46 years (range 19-94), of which 54% were women. Overall agreement on diagnoses was good, with a median kappa of 0.66. Kappa values for specific urgent diagnoses were excellent, with median kappa values of 0.84, 0.90 and 0.81, for appendicitis, diverticulitis and bowel obstruction, respectively. Abdominal CT has good inter-observer agreement in unselected patients with acute abdominal pain at the ED, with excellent agreement for specific urgent diagnoses as diverticulitis and appendicitis.

  6. Intra-abdominal pressure and abdominal compartment syndrome in acute general surgery.

    Sugrue, Michael

    2012-01-31

    BACKGROUND: Intra-abdominal pressure (IAP) is a harbinger of intra-abdominal mischief, and its measurement is cheap, simple to perform, and reproducible. Intra-abdominal hypertension (IAH), especially grades 3 and 4 (IAP > 18 mmHg), occurs in over a third of patients and is associated with an increase in intra-abdominal sepsis, bleeding, renal failure, and death. PATIENTS AND METHODS: Increased IAP reading may provide an objective bedside stimulus for surgeons to expedite diagnostic and therapeutic work-up of critically ill patients. One of the greatest challenges surgeons and intensivists face worldwide is lack of recognition of the known association between IAH, ACS, and intra-abdominal sepsis. This lack of awareness of IAH and its progression to ACS may delay timely intervention and contribute to excessive patient resuscitation. CONCLUSIONS: All patients entering the intensive care unit (ICU) after emergency general surgery or massive fluid resuscitation should have an IAP measurement performed every 6 h. Each ICU should have guidelines relating to techniques of IAP measurement and an algorithm for management of IAH.

    Purpose: To evaluate the natural history of children with abdominal Burkitt's lymphoma who had complete clinical remission and residual abdominal mass after treatment. Material and methods: The charts and imaging findings of all children with abdominal Burkitt's lymphoma treated and followed at our medical center between 1988 and 1999 were reviewed for the presence, management, clinical course, and prognosis of residual mass. Results: Only children who achieved complete clinical remission were included. The study group consisted of 33 children (20 boys and 13 girls) aged 2.6-17.6 years (mean 7.2 years). Of these, seven (20.6 %) were found to have a residual abdominal mass. Two underwent second-look operation with no evidence of viable tumor on histology. The remaining five were followed by imaging studies for 2.2-9.1 years (mean 6.1 years); none relapsed. Conclusion: Residual mass is not uncommon in children with abdominal Burkitt's lymphoma. The presence of residual mass in a child with complete clinical remission does not alter the long-term prognosis. Therefore, in children with Burkitt's lymphoma and residual mass with no other signs of disease activity, expectant watching may be appropriate. (orig.)

  9. TEM observations of crack tip: cavity interactions

    Crack tip-cavity interactions have been studied by performing room temperature deformation experiments in a transmission electron microscope on ion-irradiated type 316 stainless steel with small helium containing cavities. Slip dislocations emitted from a crack tip cut, sheared, and thereby elongated cavities without a volume enlargement. As the crack tip approached, a cavity volume enlargement occurred. Instead of the cavities continuing to enlarge until they touch, the walls between the cavities fractured. Fracture surface dimples do not correlate in size or density with these enlarged cavities

  10. Evaluation of Forty-Nine Patients with Abdominal Tuberculosis

    2014-12-01

    Full Text Available Aim: Abdominal tuberculosis is an uncommon form of extrapulmonary infection. In this study, we aimed to highlight the nonspecific clinical presentations and diagnostic difficulties of abdominal tuberculosis. Material and Method: Clinical features, diagnostic methods, and the therapeutic outcomes of 49 patients diagnosed as abdominal tuberculosis between 2003 and 2014 were retrospectively analyzed. Results: The patients were classified into four subgroups including peritoneal (28, nodal (14, intestinal (5, and solid organ tuberculosis (2. The most frequent symptoms were abdominal pain, abdominal distention and fatique. Ascites appeared to be the most frequent clinical finding. Ascites and enlarged abdominal lymph nodes were the most frequent findings on ultrasonography and tomography. Diagnosis of abdominal tuberculosis was mainly depended on histopathology of ascitic fluid and biopsies from peritoneum, abdominal lymph nodes or colonoscopic materials. Forty patients healed with standart 6-month therapy while extended treatment for 9-12 months was needed in 8 whom had discontinued drug therapy and had persistent symptoms and signs. One patient died within the treatment period due to disseminated infection. Discussion: The diagnosis of abdominal tuberculosis is often difficult due to diverse clinical presentations. The presence of ascites, personal/familial/contact history of tuberculosis, and coexisting active extraabdominal tuberculosis are the most significant marks in diagnosis. Diagnostic laparoscopy and tissue sampling seem to be the best diagnostic approach for abdominal tuberculosis.

  13. Congenital urethrovaginal fistula associated with imperforate hymen causing fetal urinary ascites and abdominal cystic lesions: A case report and literature review

    Koichi Ohno

    2015-02-01

    Full Text Available A primipara presented to our hospital due to fetal ascites, bilateral hydronephrosis and hydrometrocolpos. The female baby had two giant abdominal cysts, a single atrium and foot polydactyly. Absence of the vaginal orifice was noticed, and the hymen was broken through; the left cyst collapsed after fluid drainage. The right cyst was punctured and drained, which improved the hydronephrosis. Contrast imaging showed medium pouring into the abdominal cavity via the uterine tube; the right cyst was a 6 × 5 cm closed cavity. Vaginal uroplania persisted even after hospital discharge. At the age of 4 years, cystoscopy showed a fistulous opening on the urethra 5 mm distal from the internal urethral orifice. A catheter inserted via the opening was found in the vagina. In our case, urine poured into the abdominal cavity through the fistula and uterine tube; following obstruction of the uterine tube, giant hydrometrocolpos and hydrosalpinx appeared. Three cases of congenital urethrovaginal fistula (CUVF with imperforate hymen have been reported. A remnant of communication between the uterovaginal primordium and urogenital sinus may be responsible for CUVF.

  14. Cavity optomechanics and its applications

    Bhattacharya, Mishkatul

    2009-05-01

    Cavity optomechanics is an emerging field at the intersection of quantum optics, atomic physics, nanoscience and gravitational wave interferometry. It involves cavities (with one or more mechanical degrees of freedom) driven by laser radiation. The ensuing optical control of macroscopic mechanical motion may have implications for precision sensing, coherent control of atoms and molecules, and quantum information processing. Due to recent innovations optomechanical physics has been realized in a variety of experimental systems spanning many orders of magnitude in mass and time-scales. In this talk, I will first introduce the basic paradigm of a laser-driven two mirror cavity used for cooling a vibrational mode. A three-mirror configuration recently implemented using a partially transmissive dielectric membrane in a high finesse cavity will then be discussed, and shown to be superior to the two-mirror design in a number of ways. One implication of the three-mirror configuration is the possibility of scaling optomechanical techniques to multiple oscillators. This topic will be explored by analysing the case of two membranes in a cavity where it will be shown that the collective(center-of-mass and breathing) modes of vibration can be cooled independently, analogous to a chain of trapped ions. Finally, future directions for possible applications to the control of atoms and molecules will be indicated briefly.

  15. Development of Side Coupled Cavities

    Side coupled Cavities are good candidates for proton accelerations in the 90-180 MeV range, as it has been first proposed for the CERN LINAC4 project. A side coupled Linac is made of a lump chain of resonant cavities, alternatively accelerating and coupling. A side coupled cavity has been designed in a CERN-LPSC collaboration to achieve LINAC4 requirements. After RF studies, a complete thermal study has been done, showing that 10-15% is the absolute maximum duty-cycle achievable by such a cavity. Error studies have been developed. They have shown that a tuning ring is mandatory and that a K equals 3% coupling factor is a good choice. A prototype has been built and each cell has been measured and tuned. A simple and accurate method has been used to get both the resonant frequency and the coupling factor, with a movable tuner and a linear fit. A similar method has been used to get the second order coupling factor. A large dispersion is observed on K. This is mainly due to the shape of the coupling apertures, which are very sensitive to mechanical errors. A future and realistic design must be very careful to guarantee a constant aperture (the important parameter is more the dispersion of k than its exact value). Finally, we analyse how to tune the cavity. This has to checked carefully and probably improved or corrected. Results are expected for mid-2008

    2014-01-01

    The European Spallation Source (ESS) is a multi-disciplinary research centre under design and construction in Lund, Sweden. This new facility is funded by a collaboration of 17 European countries and is expected to be up to 30 times brighter than today's leading facilities and neutron sources. The ESS will enable new opportunities for researchers in the fields of life sciences, energy, environmental technology, cultural heritage and fundamental physics. A 5 MW long pulse proton accelerator is used to reach this goal. The pulsed length is 2.86 ms, the repetition frequency is 14 Hz (4 % duty cycle), and the beam current is 62.5 mA. It is composed of one string of spoke cavity cryomodule and two strings of elliptical cavity cryomodules. This paper introduces the thermo-mechanical design and expected operation of the ESS spoke cavity cryomodules. These cryomodules contain two double spoke bulk Niobium cavities operating at 2 K and at a frequency of 352.21 MHz. The superconducting section of the Spoke Linac accelerates the beam from 90 MeV to 220 MeV. A Spoke Cavity Cryomodule Technology Demonstrator will be built and tested in order to validate the ESS series production.

An Elliptical Cavity Cryomodule Technology Demonstrator (ECCTD) will be built and tested in order to validate the ESS series production.

  18. A SURVEY OF CORONAL CAVITY DENSITY PROFILES

    Coronal cavities are common features of the solar corona that appear as darkened regions at the base of coronal helmet streamers in coronagraph images. Their darkened appearance indicates that they are regions of lowered density embedded within the comparatively higher density helmet streamer. Despite interfering projection effects of the surrounding helmet streamer (which we refer to as the cavity rim), Fuller et al. have shown that under certain conditions it is possible to use a Van de Hulst inversion of white-light polarized brightness (pB) data to calculate the electron density of both the cavity and cavity rim plasma. In this article, we apply minor modifications to the methods of Fuller et al. in order to improve the accuracy and versatility of the inversion process, and use the new methods to calculate density profiles for both the cavity and cavity rim in 24 cavity systems. We also examine trends in cavity morphology and how departures from the model geometry affect our density calculations. The density calculations reveal that in all 24 cases the cavity plasma has a flatter density profile than the plasma of the cavity rim, meaning that the cavity has a larger density depletion at low altitudes than it does at high altitudes. We find that the mean cavity density is over four times greater than that of a coronal hole at an altitude of 1.2 Rsun and that every cavity in the sample is over twice as dense as a coronal hole at this altitude. Furthermore, we find that different cavity systems near solar maximum span a greater range in density at 1.2 Rsun than do cavity systems near solar minimum, with a slight trend toward higher densities for systems nearer to solar maximum. Finally, we found no significant correlation of cavity density properties with cavity height-indeed, cavities show remarkably similar density depletions-except for the two smallest cavities that show significantly greater depletion.

    Full Text Available Abstract Background Concurrent chemoradiation with 5-fluorouracil (5-FU is widely accepted for treatment of abdominal malignancy. Nonetheless, the interactions between radiation and 5-FU remain unclear. We evaluated the influence of abdominal irradiation on the pharmacokinetics of 5-FU in rats. Methods The radiation dose distributions of cholangiocarcinoma patients were determined for the low dose areas, which are generously deposited around the intrahepatic target volume. Then, corresponding single-fraction radiation was delivered to the whole abdomen of Sprague-Dawley rats from a linear accelerator after computerized tomography-based planning. 5-FU at 100 mg/kg was intravenously infused 24 hours after radiation. A high-performance liquid chromatography system equipped with a UV detector was used to measure 5-FU in the blood. Ultrafiltration was used to measure protein-unbound 5-FU. Results Radiation at 2 Gy, simulating the daily human treatment dose, reduced the area under the plasma concentration vs. time curve (AUC of 5-FU by 31.7% compared to non-irradiated controls. This was accompanied by a reduction in mean residence time and incremental total plasma clearance values, and volume of distribution at steady state. Intriguingly, low dose radiation at 0.5 Gy, representing a dose deposited in the generous, off-target area in clinical practice, resulted in a similar pharmacokinetic profile, with a 21.4% reduction in the AUC. This effect was independent of protein binding capacity. Conclusions Abdominal irradiation appears to significantly modulate the systemic pharmacokinetics of 5-FU at both the dose level for target treatment and off-target areas. This unexpected and unwanted influence is worthy of further investigation and might need to be considered in clinical practice.

  20. Late renal function following whole abdominal irradiation

    Sixty patients treated with whole abdominal radiotherapy who had remained disease-free since completion of treatment participated in a study to assess the late clinical and biochemical effects of bilateral renal irradiation. Minimum follow-up was 5 years with a maximum of 20 years and a median of 9 years. Fifty-two patients in the study group were treated for primary ovarian cancer. Seven had non-Hodgkins lymphoma arising in the gastrointestinal tract and one patient had a carcinoid tumour arising in small bowel. None of the patients received chemotherapy. Abdominal radiation was given using an open beam technique to a mean dose of 22.92 Gy (range 6.68-27.54 Gy) in 1.02 to 1.25 Gy fractions treated once daily. Posterior kidney shields were used in order to limit the renal dose to <20 Gy. Mean radiation dose to both kidneys (retrospectively calculated) was 19.28 Gy (range 6.68-22.99 Gy). Patients ranged in age from 32-81 years with a median of 61 years. No patient had clinical evidence of renal impairment. Nine patients were hypertensive prior to radiotherapy and a further five patients became hypertensive after treatment. Serum creatinine values ranged from 44-123 μmol/l, with a mean of 87 μmol/l. Creatinine clearance ranged from 0.61-2.38 ml/s (mean 1.28 ml/s). Tubular function tests revealed one borderline high 24-h protein excretion and normal 24-h phosphorous and uric acid. Using a multiple linear regression analysis with creatinine clearance as the endpoint, age was the only significant variable (P < 0.00001) and renal dose and interval from treatment were not independently significant. There was no evidence of late renal toxicity more than 5 years after whole abdominal radiotherapy delivered with this technique and dose/fractionation schedule, and using the clinical and biochemical endpoints assessed in this study

  2. Radiodiagnosis programs for the recognition of acute surgical diseases of the abdominal organs, retroperitoneal space and complications thereof

    Program for complex use of X-ray and ultrasonic diagnostic methods, X-ray computerized tomography was worked out in diseases of the abdominal organs, retroperitoneal space. Creation of such program was necessary due to acute surgical intervention in diseases of these organs (1750 patients with clinical picture of acute abdomen, 1350 patients with acute diseases of abdomen cavity organs). Obtaining of momentary information for diagnosis is required in most of cases. Schemes are suggested for complex usage of these diagnostic methods in different pathology, clinical symptoms, severity in patient state, technical possibilities of medical establishments

    2015-09-01

    Biophysical peculiarities of action on tissues of a two-strem low-frequency ultrasound (TSLFU) technology, elaborated by "Arobella Medical LLC" (USA) firm, were studied. Capacity of ultrasound to separate a pathologically-changed and healthy tissues, to divide the structures in accordance to their bioacoustical parameters constitutes the technology peculiarities. The presence of such a biophysical effect permits to achieve high resectability (R0) in patients with oncological diseases. Antibacterial effect and stimulation of intraorgan microcirculation with ultrasound irradiation were noted. Biophysical peculiarities of TSLFU were successfully applied in surgical treatment of 48 patients, suffering inflammatory and oncological diseases of the abdominal cavity organs. PMID:26817081

  4. Functional Abdominal Pain: "Get" the Function, Loose the Pain.

    Draeger-Muenke, Reinhild

    2015-07-01

    Functional abdominal pain is a mind-body, psychosocial, and self-reinforcing experience with significant consequences for the sufferer and the surrounding support network. The occurrence of unpredictable symptoms and their severity add an element of dread and feeling out-of-control to daily life and often reduce overall functioning in a downward spiral. Two clinical presentations of functional abdominal pain are offered in this article (composites to protect confidentiality) dealing with abdominal pain syndrome and abdominal migraines. The treatment demonstrates the use of hypnotic principles for self-regulation, exploration, and meaning-making. Hypnosis treatment is conducted in combination with mindfulness-based interventions and Traditional Chinese Medicine's (TCM) teachings regarding abdominal health and illness. The clinical examples illustrate medical findings that suggest children with early life stress and an early onset of gastrointestinal somatization may not simply outgrow their functional abdominal pain but may suffer into adulthood.

    1998-12-01

    Two patients developed chylous complications following abdominal aortic aneurysm repair. One patient had chylous ascitis and was successfully treated by a peritoneo-caval shunt. The other patient developed a lymph cyst, which gradually resorbed after puncture. Chylous complications following aortic surgery are rare. Patients in bad a general condition should be treated by initial paracentesis and total parenteral nutrition, supplemented by medium-chain triglyceride and low-fat diet. If no improvement is observed on this regimen, the next step should be implementation of a peritoneo-venous shunt, whereas direct ligation of the leak should be reserved for those who are not responding to this treatment.

  6. Mycobacterium fortuitum abdominal wall abscesses following liposuction

    Al Soub Hussam

    2008-01-01

    Full Text Available We describe here a case of abdominal abscesses due to Mycobacterium fortuitum following liposuction. The abscesses developed three months after the procedure and diagnosis was delayed for five months. The clues for diagnosis were persistent pus discharge in spite of broad spectrum antibiotics and failure to grow any organisms on routine culture. This condition has been rarely reported; however, the increasing number of liposuction procedures done and awareness among physicians will probably result in the identification of more cases. Combination antibiotic therapy with surgical drainage in more extensive diseases is essential for cure.

  7. Exercise-related transient abdominal pain (ETAP).

    Morton, Darren; Callister, Robin

    2015-01-01

    Exercise-related transient abdominal pain (ETAP), commonly referred to as 'stitch', is an ailment well known in many sporting activities. It is especially prevalent in activities that involve repetitive torso movement with the torso in an extended position, such as running and horse riding. Approximately 70% of runners report experiencing the pain in the past year and in a single running event approximately one in five participants can be expected to suffer the condition. ETAP is a localized pain that is most common in the lateral aspects of the mid abdomen along the costal border, although it may occur in any region of the abdomen. It may also be related to shoulder tip pain, which is the referred site from tissue innervated by the phrenic nerve. ETAP tends to be sharp or stabbing when severe, and cramping, aching, or pulling when less intense. The condition is exacerbated by the postprandial state, with hypertonic beverages being particularly provocative. ETAP is most common in the young but is unrelated to sex or body type. Well trained athletes are not immune from the condition, although they may experience it less frequently. Several theories have been presented to explain the mechanism responsible for the pain, including ischemia of the diaphragm; stress on the supportive visceral ligaments that attach the abdominal organs to the diaphragm; gastrointestinal ischemia or distension; cramping of the abdominal musculature; ischemic pain resulting from compression of the celiac artery by the median arcuate ligament; aggravation of the spinal nerves; and irritation of the parietal peritoneum. Of these theories, irritation of the parietal peritoneum best explains the features of ETAP; however, further investigations are required. Strategies for managing the pain are largely anecdotal, especially given that its etiology remains to be fully elucidated. Commonly purported prevention strategies include avoiding large volumes of food and beverages for at least 2 hours

    Full Text Available Roundworm infestation is common in tropical climate population with a low socioeconomic status. We describe a case of a young male with polytrauma accident who presented with small bowel dysfunction with a high gastric residual volume during enteral feeding. While searching the etiology, the intensivist performed bedside abdominal ultrasound (USG as a part of whole body USG screening along with clinical examination using different frequency probes to examine bowel movement and ultimately found ascariasis to be the cause. This case report will boost up the wide use of bedside USG by critical care physicians in their patient workup.

    2013-11-01

    Full Text Available Hydronephrosis is a condition that results from complete or partial obstruction of the urinary flow. This paper reports the case of a two-year-old, mixed-breed dog diagnosed with hydronephrosis of the left kidney six months after being kicked in the thoraco-abdominal region. The diagnosis was based on radiographic and ultrasonographic examinations. Percutaneous antegrade pyelography was also performed and allowed the visualization of opacification of the left kidney, which confirmed the diagnosis. Because the exams indicated that the patient had normal renal function, nephrectomy was performed. The patient remained in good health during the postoperative period and in subsequent evaluations.

  11. Phoxonic crystals and cavity optomechanics

    Djafari-Rouhani, Bahram; El-Jallal, Said; Pennec, Yan

    2016-05-01

    Phoxonic crystals are dual phononic/photonic crystals exhibiting simultaneously band gaps for both types of excitations. Therefore, they have the ability to confine phonons and photons in the same cavity and in turn allow the enhancement of their interaction. In this paper, we review some of our theoretical works on cavity optomechanical interactions in different types of phoxonic crystals, including two-dimensional, slab, and nanobeam structures. Two mechanisms are behind the phonon-photon interaction, namely the photoelastic and the moving interface effects. Coupling rates of a few MHz are obtained with high-frequency phonons of a few GHz. Finally, we give some preliminary results about the optomechanical interaction when a metallic nanoparticle is introduced into the cavity, giving rise to coupled photon-plasmon modes or, in the case of very small particles, to an enhancement of the electric field at the position of the particle. xml:lang="fr"

  12. Crab cavities for the LHC

    For the high-luminosity LHC upgrade program (HL-LHC), the installation of crab cavities (CC) is essential to compensate the geometric luminosity loss due to the crossing angle and for luminosity leveling. One of the major challenges is the compatibility with machine protection in the regime of >500 MJ stored beam energy. Especially in a failure case (e.g. a CC quench or sparking in the coupler), the voltage and/or phase of a CC can change significantly with a fast time-constant of the order of a LHC-turn. This can lead to large, global betatron oscillations of the beam. The status of the LHC crab cavity upgrade program is presented and the influence of crab cavities on the beam dynamics is discussed. Necessary countermeasures to limit the impact of CC failures to an acceptable level are specified and operational scenarios that are compatible with machine protection considerations are proposed.

  13. RRR Characteristics for SRF cavities

    Jung, Yoochul; Hyun, Myungook; Joung, Mijoung

    2015-10-01

    The first heavy ion accelerator is being constructed by the rare isotope science project (RISP) launched by the Institute of Basic Science (IBS) in South Korea. Four different types of superconducting cavities were designed, and prototypes such as a quarter-wave resonator (QWR), a half-wave resonator (HWR) and a single-spoke resonator (SSR) were fabricated. One of the critical factors determining the performances of superconducting cavities is the residual resistance ratio (RRR). The RRR values essentially represent how pure niobium is and how fast niobium can transmit heat. In general, the RRR degrades during electron beam welding due to impurity incorporation. Thus, it is important to maintain the RRR above a certain value at which a niobium cavity shows target performance. In this study, RRR degradation related with electron beam welding conditions, for example, the welding power, welding speed, and vacuum level, will be discussed.

    We report a rare case of huge abdominal desmoid tumour first detected during pregnancy. The patient delivered vaginally and the size of the tumour increased during puerperium for which resection was done. Most of these tumours occur in the abdominal muscles particularly right rectus abdominis, perhaps related to trauma from abdominal stretching and movement. These tumours are known to regress spontaneously after delivery which was not in our case. Subsequent pregnancies do not appear to resul...

Immediate revascularization through aortic thrombo-endoarterectomy resolved the disease. PMID:23830410

  3. [Influences of chest deformation by upper abdominal retractor on respiratory system impedance during abdominal surgery].

    Oka, T; Ozawa, Y; Sato, J

    1999-02-01

    The present study was carried out to clarify the effects of chest deformation by upper abdominal retractor on respiratory system impedance during abdominal surgery. We measured the impedances of respiratory system (RS), lung, and chest wall (CW) in nine anesthetized paralyzed subjects employing a pseudorandom noise forced volume oscillation technique. These measurements were performed before and after the lifting chest wall by upper abdominal retractor. The effects of chest deformation was significant on the impedances of RS, lung, while no discernible effect was found in CW impedance. Lifting chest wall decreased RS resistance which was totally accounted for by the decrease in lung resistance, whereas the lifting did not affect reactance in either RS or lung. The mathematical modeling showed the significant lifting effect on the resistance of the parenchyma. In conclusion, change in RS mechanics produced by chest deformation by upper abdominal retractor is dominated in lung but not in CW. Among the lung mechanical components, parenchyma is the primary site of the lifting effect. PMID:10087819

  4. Prevalence of abdominal migraine and recurrent abdominal pain in a Japanese clinic.

    Hikita, Toshiyuki

    2016-07-01

    Prevalence of abdominal migraine (AM) and recurrent abdominal pain (RAP) was evaluated in patients who visited Hikita Pediatric Clinic between May 2010 and April 2015. Patient data were collected prospectively using a questionnaire. Out of a total of 3611 cases, observed prevalence was 2.44% for repeated abdominal pain over a period of ≥3 months, 1.47% for RAP, and 0.19% for AM. Duration of abdominal pain was longer for AM than for non-AM RAP. Certain clinical features were significantly different between AM and non-AM RAP. No correlations were found among age at onset, frequency of attack, and duration of attack for various types of RAP. It was difficult to determine useful diagnostic criteria for distinguishing between AM and non-AM RAP. They did not appear to be separate disease entities but, instead, lie on a disease spectrum. The present prevalence of AM (0.19%) was lower than that in many previous studies from countries other than Japan. PMID:27460403

    Full Text Available We review advances on the experimental study of cavity solitons in VCSELs in the past decade. We emphasize on the design and fabrication of electrically or optically pumped broad-area VCSELs used for CSs formation and review different experimental configurations. Potential applications of CSs in the field of photonics are discussed, in particular the use of CSs for all-optical processing of information and for VCSELs characterization. Prospects on self-localization studies based on vertical cavity devices involving new physical mechanisms are also given.

  6. Protein dynamics: hydration and cavities

    K. Heremans

    2005-08-01

    Full Text Available The temperature-pressure behavior of proteins seems to be unique among the biological macromolecules. Thermodynamic as well as kinetic data show the typical elliptical stability diagram. This may be extended by assuming that the unfolded state gives rise to volume and enthalpy-driven liquid-liquid transitions. A molecular interpretation follows from the temperature and the pressure dependence of the hydration and cavities. We suggest that positron annihilation spectroscopy can provide additional quantitative evidence for the contributions of cavities to the dynamics of proteins. Only mature amyloid fibrils that form from unfolded proteins are very resistant to pressure treatment.

    Shlomi, Keren; Yuvaraj, D; Baskin, Ilya; Suchoi, Oren; Winik, Roni; Buks, Eyal

    2015-03-01

    We study self-excited oscillations (SEO) in an on-fiber optomechanical cavity. Synchronization is observed when the optical power that is injected into the cavity is periodically modulated. A theoretical analysis based on the Fokker-Planck equation evaluates the expected phase space distribution (PSD) of the self-oscillating mechanical resonator. A tomography technique is employed for extracting PSD from the measured reflected optical power. Time-resolved state tomography measurements are performed to study phase diffusion and phase locking of the SEO. The detuning region inside which synchronization occurs is experimentally determined and the results are compared with the theoretical prediction. PMID:25871175

  10. Analysis of the body composition of the abdominal region by means of C.T

    The C.T. photographic figures of the horizontal cross sectional planes at the five levels in the abdominal region (Xiphoid level-E6, Upper abdomen level-E7, Umbilicus level-E8, Lower abdomen level-E10, Public symphisis level-E12) were analyzed. The subcutaneous fatty layer, the muscular layer, the bony layer and the body cavity were recognized on the figure and measured, then the body composition at each planes and factors affecting to it were investigated. Subjects included 10 adult males and 16 adult females. They were divided into following three groups on the basis of the Rohrer index: A-type (129 and below), C-type (from 130 to 149) and D-type (150 and above). Among the differences of the body composition in each plane caused by the sex and somatotype, the most dominant component constituting the total cross sectional area was observed and the following results were obtained : 1. At the E6 and E7 planes : the dominant component was the body cavity redardless of the sexual and type defferences. 2. At the E8 and E10 planes : the dominant component was, in males, the muscular layer in A-type, the body cavity in C-type and the fatty layer in D-type, whereas, in females, the body cavity in A and C-type, and the fatty layer in D-type. 3. At the E12 planes : the dominant component was, in males, the muscular layer in A and C-type, and the fatty layer in D-type, whereas, in females, the muscular layer in A-type and the fatty layer in C and D-type.

  13. Value of abdominal CT in the emergency department for patients with abdominal pain

    The purpose of our study is to demonstrate the value of CT in the emergency department (ED) for patients with non-traumatic abdominal pain. Between August 1998 and April 1999, 536 consecutive patients with non-traumatic abdominal pain were entered into our study. Using a computer order entry system, physicians were asked to identify: (a) their most likely diagnosis; (b) their level of certainty in their diagnosis; (c) if they thought CT would be normal or abnormal; (d) their treatment plan (prior to knowledge of the CT results); and (e) their role in deciding to order CT. This information was correlated with each patient's post-CT diagnosis and subsequent management. Pre- and post-CT diagnoses were concordant in 200 of 536 (37%) patients. The physicians' certainty in the accuracy of their pre-CT diagnosis was less than high in 88% of patients. Prior to CT, the management plan included hospital admission for 402 patients. Following CT, only 312 patients were actually admitted; thus, the net impact of performing CT was to obviate the need for hospital admission in 90 of 536 (17%) of patients with abdominal pain. Prior to CT, 67 of 536 (13%) of all patients would have undergone immediate surgery; however, following CT only 25 (5%) actually required immediate surgery. Among patients with the four most common pre-CT diagnoses (appendicitis, abscess, diverticulitis, and urinary tract stones) CT had the greatest impact on hospital admission and surgical management for patients with suspected appendicitis. For patients with suspected appendicitis, CT reduced the hospital admission rate in 28% (26 of 91) of patients and changed the surgical management in 40% (39 of 91) of patients. Our study demonstrates the advantage of performing abdominal CT in the ED for patients with non-traumatic abdominal pain. (orig.)

  14. [Endometriosis in the abdominal wall (author's transl)].

    Caligaris, P; Masselot, R; Ducassou, M J; Le Treut, Y; Bricot, R

    1981-01-01

    The authors give 9 case histories of endometriosis localised to the abdominal wall : 3 of them in the umbilicus, 3 in laparotomy incisions (2 of those were Caesareans), 2 of them in the round ligaments at the external opening of the inguinal canal and 1 of them in the right rectus muscle sheath in the abdomen. The functional symptomatology is rhythmical according to menstruation; it is associated with a burning type of pain, a tumour and blood loss. Over and above the theories of aetiology that are now classical, namely tubal retrograde spill, and lymphatic or venous spread, it would seem that prostaglandins and in particular the ratio of P.G.E. divided by P.D.F2 alpha can play a big role. Although Danazol is an effective treatment for endometriosis, the treatment of choice is, in these lesions that are superficial in localisation and easily accessible, to cut them out surgically. This makes it possible on the one hand to look for other intra-abdominal lesions and also on the other hand to confirm the anatomy and pathology (this was done in 7 out of 9 of our cases).

  15. Imaging modalities of abdominal tumors in children

    Further technological progress in cross-sectional imaging modalities, accumuting experience with increasingly refined hardware and software and accumulating specific contrast media allow new algorithms for the assessment of abdominal tumors in children. However, ultrasound remains the diagnostic method of choice: Conventional roentgenology with or without contrast media is decreasing, but often reveals further differential diagnostic details. MRI is becoming more prominent and is often performed immediately after ultrasound. The inauguration of gradient echo sequences and consequent shorter examination times combined with the elimination of pulsation and motion artefacts extends the diagnostic spectrum of the upper and middle abdomen. The application of oral or rectal contrast agents for imaging of the GI tract ameliorates the differentiation of pathologic processes. Recently volumetric CT/ultrafast CT has been gaining in importance for abdominal examinations in the pediatric age group. CT especially is helpful if there are bony structures in the region being examined. CT, however, involves ionizing radiation and timely administration of oral and intravenous contrast material. Moreover, as pediatric radiologists, we must strongly withstand tendencies to perform CT more often because it is less expensive, rather than avoiding ionizing radiation by using MRI. (orig.)

  16. Abdominal manifestations of cystic fibrosis in children

    Pulmonary complications remain the main cause of mortality in cystic fibrosis, but the presenting symptoms in children are often related to gastrointestinal or pancreaticobiliary disease. Furthermore, abdominal manifestations are now seen throughout childhood, from infancy to adolescence. The child might present in the neonatal period with meconium ileus or its attendant complications. The older child might present with distal intestinal obstruction syndrome or colonic stricture secondary to high doses of pancreatic enzyme replacement. Less-common gastrointestinal manifestations include intussusception, duodenitis and fecal impaction of the appendix. Most children also show evidence of exocrine pancreatic deficiency. Radiologically, the combination of fat deposition and pancreatic fibrosis leads to varying CT and MR appearances. A higher than normal incidence of pancreatic cysts and calcification is also seen. Decreased transport of water and chloride also increases the viscosity of bile, with subsequent obstruction of the biliary ductules. If extensive, this can progress to obstructive cirrhosis, portal hypertension and esophageal varices. Diffuse fatty infiltration, hypersplenism and gallstones are also commonly seen in these patients. We present a pictorial review of the radiological appearance of these abdominal manifestations. The conditions are dealt with individually, together with typical appearances in various imaging modalities. (orig.)

  18. Abdominal computed tomography in malignant lymphoma

    The computed tomographic findings of malignant lymphoma in the pelvis and abdomen is described. Characteristic symptoms are lymph node enlargement in the diameter greater than 1,0 cm, obliteration of the contour of the surrounding structures and displacement of the neighbouring organs. In contrast to the conventional lymphography, CT gives information about mesenterial and retrocrural lymph nodes. In patients with involvement of liver and spleen, CT defines only the size of the organs, because of differences in density to normal patients are seldom observed and focal lesions are rare. 71 patients with newly diagnosed, histologically proved and untreated malignant lymphoma are investigated by CT. In 27 patients CT detected pathological findings, the sensitivity was 72%, the specifity 100%. False-negative results has been attributed to the failure to identify not enlarged, but involved lymph nodes and involved liver and spleen without focal lesions or enlargement. CT replaces lymphography in diagnosis and staging of patients with abdominal malignant lymphoma, lymphography is indicated only in patients with expected abdominal disease and normal CT to identify involved, not enlarged lymph nodes.

    2011-01-01

    Full Text Available Abdominal-pelvic actinomycosis is often mistaken for other conditions, presenting a preoperative diagnostic challenge. In a 46-year-old female, computed tomography showed an abdominal-pelvic retroperitoneal mass extending from the lower pole of the right kidney to the lower pelvis. The patient had a 3-year history of intrauterine device. The mass appeared to involve the ascending colon, cecum, distal ileum, right Fallopian tube and ovary, and ureter anteriorly and the psoas muscle posteriorly. The resection of retroperitoneal mass, distal ileum appendicectomy, right hemicolectomy, and right salpingo-oophorectomy was performed. The postoperative period was uneventful. Penicillin therapy was given for six months without any complication. The retroperitoneal mass measured 4.5 × 3.5 × 3 cm, surrounded adjacent organs and histologically showed inflammatory granulomatous tissue, agglomeration of filaments, and sulfur granules of Actinomyces, with positive reaction with periodic acid Schiff. Right tubo-ovarian abscess was present. Abdominalpelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intrauterine device.

    Ultrasonography is a very useful diagnostic modality for the evaluation of clinically suspicious abdominal masses in infants and children, especially in assessing their existence, size, location, origin and internal consistency. Authors analyzed and present ultrasonographic findings of 92 pathologically and/or clinically proven pediatric abdominal masses that were studied and treated in Chonnam University Hospital during recent 4 years. The results were as follows: 1. The most common originating site was kidney (26 cases: 28.3%), followed by gastrointestinal tract (21 cases: 22.8%), genital organ (17 cases: 18.5%), non-renal retroperitoneum (13 cases: 18.5%), hepatobiliary tract (12 cases: 13.0%), and anterior abdominal wall (3 cases: 3.3%) in order to frequency. 2. The most common mass was hydronephrosis (18 cases: 19.6%). Neuroblastoma (7 cases: 7.6%), hepatoblatoma, ovarian teratoma, periappendiceal abscess and abdominal tuberculosis (6 cases: 6.5%, respectively), Wilms tumor (5 cases: 5.4%) were next in order of frequency. 3. The sex distribution is rather similar, that is, male 42 (45.7%) and female 50 (54.3%), but characteristically choledochal cyst (2 cases) and genital mass (17 cases) were found only in females. Considering age distribution, 78 cases (84.8%) were found within the range of one to 15 years of age. The rest, 14 cases (15.2%), were under the age of one year. 4. With ultrasonography, the diagnosis of hydronephrosis could be made easily in every case and we could evaluate its severity and level of obstruction with high accuracy. 5. All Wilms tumor were large, round or oval, sharply marinated and relatively homogeneous solid masses. 6. All neuroblastomas were irregular shaped, poorly defined, heterogeneous solid masses. Tumor calcification and extension across the midline were noted in 6 cases (85.7%) and 5 cases (71.4%), respectively. 7. All periappendiceal abscess had irregular thickened wall and posterior acoustic enhancement; 4 cases (66

  2. Inhibition of Tumor Growth in Mice by Endostatin Derived from Abdominal Transplanted Encapsulated Cells

    Huaining TENG; Ying ZHANG; Wei WANG; Xiaojun MA; Jian FEI

    2007-01-01

    Endostatin, a C-terminal fragment of collagen 18a, inhibits the growth of established tumors and metastases in vivo by inhibiting angiogenesis. However, the purification procedures required for largescale production and the attendant cost of these processes, together with the low effectiveness in clinical tests, suggest that alternative delivery methods might be required for efficient therapeutic use of endostatin.In the present study, we transfected Chinese hamster ovary (CHO) cells with a human endostatin gene expression vector and encapsulated the CHO cells in alginate-poly-L-lysine microcapsules. The release of biologically active endostatin was confirmed using the chicken chorioallantoic membrane assay. The encapsulated endostatin-expressing CHO cells can inhibit the growth of primary tumors in a subcutaneous B16 tumor model when injected into the abdominal cavity of mouse. These results widen the clinical application of the microencapsulated cell endostatin delivery system in cancer treatment.

  6. Hydrofracture from a growing cavity

    The Los Alamos KRAK code has been used to calculate fracturing away from the growing cavity formed by a nuclear detonation. In the 55 ms before rebound, the stress in the surrounding rock is decreasing, and conditions for fracture propagation are good. During this interval, hydrofractures driven by the high-temperature, high-pressure gases within the cavity grow readily. Fracture growth slows when the stress increases as the residual hoop is formed during rebound. However, cracks are found to escape through the residual stress field. The effects of initial conditions and zoning on the numerical calculations are discussed, and the roles of the media saturation and roughness are briefly considered. The largest uncertainty in these calculations is the manner in which the effective pressure used in computing crack widths is extended into the cavity region. Because the present calculations have been done using a very conservative scheme, actual fractures should grow even more readily. We conclude that hydrofracture is an important, if not dominant, process in transporting mass and energy out of a cavity formed by a nuclear detonation

  7. Cavity length below chute aerators

    2008-01-01

    It is proved that air entrainment is one of the efficient measures dealing with cavitation control for the release works of hydropower projects. There are many factors to be considered in designing a chute aerator. One of the most important factors concerns the cavity length below the aerator, which has outstanding effects on air entrainment against cavitation damage. It is crucial to determine reasonable emergence angle for the calculation of the cavity length. In the present paper the overall effects of structural and hydraulic parameters on the emergence angle of the flow from the aerator were analyzed. Four improved expressions of the emergence angle with weight coefficient were investigated through experimental data of 68 points observed from 12 aerators of 6 hydropower projects, of both model and prototype, on the basis of error theory. A method to calculate the cavity length below aerators was suggested, which considers overall effects of the above mentioned parameters. Comparison between the method in this paper and the other five methods of calculating the cavity length showed that the present method is much more reliable than the existing methods while the mean error of the method is less than others.

    In passive enhancement cavities the achievable power level is limited by mirror damage. Here, we address the design of robust optical resonators with large spot sizes on all mirrors, a measure that promises to mitigate this limitation by decreasing both the intensity and the thermal gradient on the mirror surfaces. We introduce a misalignment sensitivity metric to evaluate the robustness of resonator designs. We identify the standard bow-tie resonator operated close to the inner stability edge as the most robust large-mode cavity and implement this cavity with two spherical mirrors with 600 mm radius of curvature, two plane mirrors and a round trip length of 1.2 m, demonstrating a stable power enhancement of near-infrared laser light by a factor of 2000. Beam radii of 5.7 mm × 2.6 mm (sagittal × tangential 1/e(2) intensity radius) on all mirrors are obtained. We propose a simple all-reflective ellipticity compensation scheme. This will enable a significant increase of the attainable power and intensity levels in enhancement cavities. PMID:23670017

  11. Nanobeam cavities for Reconfigurable Photonics

    Deotare, Parag B.

    We investigate the design, fabrication, and experimental characterization of high quality factor photonic crystal nanobeam cavities, with theoretical quality factors of 1.4 x 107 in silicon, operating at ˜ 1550 nm. By detecting the cross-polarized resonantly scattered light from a normally incident laser beam, we measure a quality factor of nearly 7.5 x 105. We show on-chip integration of the cavities using waveguides and an inverse taper geometry based mode size converters, and also demonstrate tuning of the optical resonance using thermo-optic effect. We also study coupled cavities and show that the single nanobeam cavity modes are coupled into even and odd superposition modes. Using electrostatic force and taking advantage of the highly dispersive nature of the even mode to the nanobeam separation, we demonstrate dynamically reconfigurable optical filters tunable continuously and reversibly over a 9.5 nm wavelength range. The electrostatic force, obtained by applying bias voltages directly to the nanobeams, is used to control the spacing between the nanobeams, which in turn results in tuning of the cavity resonance. The observed tuning trends were confirmed through simulations that modeled the electrostatic actuation as well as the optical resonances in our reconfigurable geometries. Finally we demonstrate reconfiguration of coupled cavities by using optical gradient force induced mechanical actuation. Propagating waveguide modes that exist over wide wavelength range are used to actuate the structures and in that way control the resonance of a localized cavity mode. Using this all-optical approach, more than 18 linewidths of tuning range is demonstrated. Using an on-chip temperature self-referencing method that we developed, we determined that 20% of the total tuning was due to optomechanical reconfiguration and the rest due to thermo-optic effects. By operating the device at frequencies higher than the thermal cut-off, we show high speed operation dominated by

  12. Abdominal tuberculosis. On-going challenge to gastroenterologists

    The aim of this study is to record the observations and experience on the diagnosis and management of abdominal tuberculosis (TB) and to highlight the difficulties in the diagnosis and management of this condition. Two hundred consecutive patients attending the Gastroenterology Department of the King Khalid National Guard Hospital, Jeddah, Kingdom of Saudi Arabia between May 1991 and May 2001, suspected with abdominal TB were investigated. A detailed clinical history and physical examination were obtained. Data of 75 confirmed cases of abdominal TB were analyzed. The most common presenting symptoms were anorexia (84%), abdominal pain (84%) and weight loss (72%). Abdominal tenderness was the most common clinical finding, followed by ascites and abdominal mass (42%). The chest radiograph suggestive of pulmonary TB was diagnosed in 24 patients (32%). Computed tomographic (CT) scanning revealed abnormalities in all 51 patients who underwent the procedure, while positive findings were observed by abdominal ultrasound in 66% of the tested patients. Histopathological examination of patients showed tuberculosis granuloma, while acid fast bacilli were seen in 34%. Mycobacterium tuberculosis was identified by microbiological methods in 60% of patients. The most common presenting symptoms were anorexia (84%), abdominal pain (84%) and weight loss (72%).

    2003-01-01

    Full Text Available OBJECTIVE AND METHODS: Screening for abdominal aortic aneurysms may be useful to decrease mortality related to rupture. We conducted a study to assess the prevalence of abdominal aortic aneurysms in southern Brazil and to define risk factors associated with high prevalence of this disorder. The screening was conducted using abdominal ultrasound. Three groups were studied: Group 1 - cardiology clinic patients; Group 2 - individuals with severe ischemic disease and previous coronary surgery, or important lesions on cardiac catheterism; Group 3 - individuals without cardiac disease selected from the general population. All individuals were male and older than 54 years of age. The ultrasonographic diagnosis of aneurysm was based on an anteroposterior abdominal aorta diameter of 3 cm, or on an abdominal aorta diameter 0.5 cm greater than that of the supra-renal aorta. RESULTS: A total of 2.281 people were screened for abdominal aortic aneurysms in all groups: Group 1 - 768 individuals, Group 2 - 501 individuals, and Group 3 - 1012 individuals. The prevalence of aneurysms was 4.3%, 6.8% and 1.7%, respectively. Age and cigarette smoking were significantly associated with increased prevalence of aneurysms, as was the diagnosis of peripheral artery disease. DISCUSSION: We concluded that screening may be an important tool to prevent the mortality associated with abdominal aortic aneurysms surgery. Additionally, the cost of screening can be decreased if only individuals presenting significant risk factors, such as coronary and peripheral artery disease, smokers and relatives of aneurysm patients, are examined.OBJETIVO E MÉTODOS: O rastreamento de aneurisma da aorta abdominal infra-renal é importante pois pode diminuir a mortalidade relacionada à ruptura.

  3. Practical Approaches to Definitive Reconstruction of Complex Abdominal Wall Defects.

    Latifi, Rifat

    2016-04-01

    With advances in abdominal surgery and the management of major trauma, complex abdominal wall defects have become the new surgical disease, and the need for abdominal wall reconstruction has increased dramatically. Subsequently, how to reconstruct these large defects has become a new surgical question. While most surgeons use native abdominal wall whenever possible, evidence suggests that synthetic or biologic mesh needs to be added to large ventral hernia repairs. One particular group of patients who exemplify "complex" are those with contaminated wounds, enterocutaneous fistulas, enteroatmospheric fistulas, and/or stoma(s), where synthetic mesh is to be avoided if at all possible. Most recently, biologic mesh has become the new standard in high-risk patients with contaminated and dirty-infected wounds. While biologic mesh is the most common tissue engineered used in this field of surgery, level I evidence is needed on its indication and long-term outcomes. Various techniques for reconstructing the abdominal wall have been described, however the long-term outcomes for most of these studies, are rarely reported. In this article, I outline current practical approaches to perioperative management and definitive abdominal reconstruction in patients with complex abdominal wall defects, with or without fistulas, as well as those who have lost abdominal domain.

  4. Computed tomography and nonoperative treatment for blunt abdominal trauma

    Studies were undertaken to determine if computed tomography (CT) could reliably assist physical examination in the initial assessment of blunt abdominal trauma, and also to examine how various abdominal injuries were managed with the guidance of CT. A total of 255 patients underwent emergency abdominal CT following blunt abdominal trauma over a period of seven years. One hundred and fifty two patients had abnormal CT scans, including 58 hepatic, 36 renal, 25 splenic and 9 pancreatic injuries as well as 67 patients with intra-abdominal hemorrhage and 21 patients with free abdominal air. A comparative study on the detection of pneumoperitoneum revealed CT to be far superior to plain radiography. One hundred and three patients had normal CT scans, all of whom were managed nonoperatively, except for three false-negative cases and two nontherapeutic cases. The patients with injury to the parenchymal organs were given nonoperative treatment if they had stable vital signs and no evidence of associated injuries demanding immediate surgery and the majority of these patients were managed well nonoperatively. CT was thus found to be a useful adjunct in the management of victims of blunt abdominal trauma, since in a rapid and noninvasive fashion, CT accurately defined the extent of parenchymal organ injury and also disclosed any other abdominal injuries.

The storage cavities had 4 portholes, 1 each for: RF feed; tuning; connection to the accelerating cavity; vacuum pump. The final storage cavities were larger, to suit the lower LEP accelerating frequency of 352.2 MHz. See also 8002294, 8006510X, 8109346, 8407619X, and Annual Report 1980, p.115.

    We present the results of numerical simulations of the electrostatics and dynamics of water hydration shells surrounding Kihara cavities given by a Lennard-Jones (LJ) layer at the surface of a hard-sphere cavity. The local dielectric response of the hydration layer substantially exceeds that of bulk water, with the magnitude of the dielectric constant peak in the shell increasing with the growing cavity size. The polar shell propagates into bulk water to approximately the cavity radius. The s...

    The clinical and post mortem features of 11 cases of lymphosarcoma involving the thoracic cavity are reviewed. The clinical findings included inappetence, weight loss, pectoral oedema, dyspnoea, pleural effusion and distension of the jugular veins. Dysphagia was present in three cases. At post mortem examination lesions were found in the abdomen as well as the chest in eight cases; clinical signs of abdominal disease were present in two cases. The features of nine other similar cases recorded in the literature are reviewed. PMID:3841057

  13. An unusual cause of abdominal pain.

    Mc Cabe, Aileen

    2011-01-01

    A 26-year-old man presented to the Emergency Department with abdominal pain, diarrhoea, anorexia and haematemesis. The patient was previously diagnosed with latent tuberculosis (TB). On examination, his abdomen was diffusely tender, with localised guarding in the right iliac fossa. CT imaging of his abdomen and pelvis demonstrated a low volume of ascites, diffuse studding of the peritoneum, omental caking and several bulky low-density lymph nodes in the retroperitoneum. A laparoscopy was performed to obtain a peritoneal biopsy. Histology demonstrated fragments of peritoneum with necrotising granulomatous inflammatory infiltrate in keeping with an infectious process, favouring TB. He was commenced on rifampicin, isoniazid, pyrazinamide, ethambutol and pyridoxine under the direct observed therapy by the infectious diseases team. In view of his extensive peritoneal involvement, he was empirically started on high-dose prednisolone for symptomatic control and to reduce complications related to peritoneal adhesions.

    PURPOSE: The aim is to provide a complete overview of the different simulation-based training options for abdominal ultrasound and to explore the evidence of their effect. MATERIALS AND METHODS: This systematic review was performed according to the PRISMA guidelines and Medline, Embase, Web of...... evidence, and 14 had the lowest level. Bias was high for 11 studies, low for four, and unclear for two. No studies used a test with established evidence of validity or examined the correlation between obtained skills on the simulators and real-life clinical skills. Only one study used blinded assessors....... CONCLUSION: The included studies were heterogeneous in the choice of simulator, study design, participants, and outcome measures, and the level of evidence for effect was inadequate. In all studies simulation training was equally or more beneficial than other instructions or no instructions. Study designs...

  15. Abdominal muscle function and incisional hernia

    Jensen, K K; Kjaer, M; Jorgensen, L N

    PURPOSE: Although ventral incisional hernia (VIH) repair in patients is often evaluated in terms of hernia recurrence rate and health-related quality of life, there is no clear consensus regarding optimal operative treatment based on these parameters. It was proposed that health-related quality...... of life depends largely on abdominal muscle function (AMF), and the present review thus evaluates to what extent AMF is influenced by VIH and surgical repair. METHODS: The PubMed and EMBASE databases were searched for articles following a systematic strategy for inclusion. RESULTS: A total of seven...... studies described AMF in relation to VIH. Five studies examined AMF using objective isokinetic dynamometers to determine muscle strength, and two studies examined AMF by clinical examination-based muscle tests. CONCLUSION: Both equipment-related and functional muscle tests exist for use in patients...

  16. Changing spleen size after blunt abdominal trauma

    The authors studied the incidence and significance of splenic enlargement on serial CT after abdominal trauma. Spleen size and density in 44 trauma patients were studied with serial, contrast-enhanced Ct. In 58% of the patients, ≥ 10% enlargement of the spleen was seen on follow-up scans. Ten patients had >50% enlargement. In several, the initial density of the spleen was less than that of the liver. Spleen density returned to normal on subsequent scans. Correlations between splenic changes and clinical parameters (such as blood replacement, hypotension, and various trauma indexes) were weak. The author's study indicated that serial splenic enlargement was a physiologic return to normal after major trauma, not a pathologic condition requiring splenectomy

  17. Intra-Abdominal Hematoma Following Enoxaparin Injection.

    Chung, Kin Tong

    2016-01-01

    An elderly patient, who was being treated for therapeutic enoxaparin for a couple of days due to suspected deep vein thrombosis, was admitted to hospital following a collapse and severe abdominal pain. She was in hypovolemic shock and was fluid resuscitated. Ultrasound scan and computed tomography (CT) scan showed a large pelvic hematoma. Radiologists also suspected a possibility of bleeding from inferior epigastric artery following a CT angiogram. The patient was stabilized and transferred to intensive care unit (ICU) for further hemodynamic supports and close monitoring. The patient was then transferred back to the general ward when she was stable. She was managed conservatively as there were no more signs of active bleeding. Unfortunately, she died of recurrent bleeding three days after ICU discharge. PMID:27158226

    The analysis of the results of 50 patients with diseases of coronary heart disease (25 pers.) And chronic pancreatitis (25 people) are submitted. Along with the standard test from these patients underwent Doppler-ultrasonography of abdominal aorta and its visceral branches. Conclusions: A characteristic feature of Doppler indices in AIC is to reduce Vps and Ved, and PI BbA, increase Vps, Ved, IR and PI after exercise in chBA, chC and BbA. At patients with CP with IHD feature is the increase in Ved and IR in the chC, and Ved and PI in BbA under act of loading Bleed a feature at CP with IHD must be taken into account for optimization of treatment of IHD at CP.

  19. Standardized anatomic space for abdominal fat quantification

    The ability to accurately measure subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) from images is important for improved assessment and management of patients with various conditions such as obesity, diabetes mellitus, obstructive sleep apnea, cardiovascular disease, kidney disease, and degenerative disease. Although imaging and analysis methods to measure the volume of these tissue components have been developed [1, 2], in clinical practice, an estimate of the amount of fat is obtained from just one transverse abdominal CT slice typically acquired at the level of the L4-L5 vertebrae for various reasons including decreased radiation exposure and cost [3-5]. It is generally assumed that such an estimate reliably depicts the burden of fat in the body. This paper sets out to answer two questions related to this issue which have not been addressed in the literature. How does one ensure that the slices used for correlation calculation from different subjects are at the same anatomic location? At what anatomic location do the volumes of SAT and VAT correlate maximally with the corresponding single-slice area measures? To answer these questions, we propose two approaches for slice localization: linear mapping and non-linear mapping which is a novel learning based strategy for mapping slice locations to a standardized anatomic space so that same anatomic slice locations are identified in different subjects. We then study the volume-to-area correlations and determine where they become maximal. We demonstrate on 50 abdominal CT data sets that this mapping achieves significantly improved consistency of anatomic localization compared to current practice. Our results also indicate that maximum correlations are achieved at different anatomic locations for SAT and VAT which are both different from the L4-L5 junction commonly utilized.
