    Full Text Available 49 year-old man presented to our clinic for pain in the right hypochondrium, diarrhea, and fever. The clinical examination highlights a tumoral formation in the right side of the abdomen, with firm consistency, poorly defined margins, and present mobility in the deep structures. On biological exams, leukocytosis with neutrophilia, inflammatory syndrome, and hypoalbuminaemia were identified. The first computed tomography exam described parietal thickening of the ascending colon, with infiltrative aspect, and multiple local adenopathies, lomboaortic and interaortocave. Moreover, four nodular liver tumors, with hypodense image in native examination, were identified. The lab tests for infectious diseases were all inconclusives: three hemocultures, three stool samples, and three coproparasitological exams were all negatives. Interdisciplinary examinations, internal medicine and infectious diseases, sustained the diagnosis of colonic neoplasm with peritumoral abscess and liver pseudo-tumoral masses. The colonoscopy did not revealed any bowel lesions relevant for neoplasia. This result as well as the bio-clinical context imposed abstention from surgical intervention. Wide spectrum antibiotics and symptomatic treatment were initiated. But, ten days after hospitalization, the second computed tomography exam showed reduction of the ascending colon wall thickness associated with significant increases of the liver tumors is so revealed. The investigations for other possible etiologies were so continued.

    2009-08-01

    We describe a 13-month-old female who presented with vaginal bleeding, breast and pubic hair development and an abdominal mass. She underwent emergency laparotomy and left-sided salpingoophorectomy. Histological examination of the resected ovary revealed massive ovarian oedema, a rare non-neoplastic enlargement of the ovary. Consideration of this diagnosis in patients with an abdominal mass and endocrine disturbance may allow conservative surgery and preservation of fertility.

    2001-11-01

    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.)

    Full Text Available Abdominal actinomycosis in childhood period is very rare and a relation to trauma is not well established. Herein we report a case that appeared subsequent to abdominal trauma. A 17 years old boy presented with left lower quadrant abdominal mass and signs of acute abdomen. The symptoms of abdominal discomfort began after a fall from height 3 months before admission. There were signs of acute abdomen at physical examination. Ultrasound of abdomen demonstrated a mass; CT scan findings pointed to a suspicious “internal hernia”. An emergency laparotomy was performed. During surgery, a mass located over sigmoid colon and infiltrating the lateral abdominal wall was found. It was removed en bloc with the adjacent omentum. Except for the thickened sigmoid colon, no other pathologies were present at laparotomy. The pathology specimen revealed the actinomyces infection. The patient was treated with oral penicillin after discharge and the follow-up was uneventful. We advocate, keeping the actinomyces infection in mind in cases presenting with abdominal mass of unknown origin in childhood period.

    INTRODUCTION Discovery of abdominal masses often poses significant diagnostic difficulties. GISTs are mesenchymal masses, with specific histological features. Dimensions may vary from millimeters to giant tumours. We would like to present our case, which had an unexpectedly easy operative course which was easily handled with a simple surgical excision with a short operative duration. PRESENTATION OF CASE A 38 years old female patient was diagnosed to have an abdominal heterogen mass of 15 cm × 12 cm × 10 cm in dimension. Abdominal computed tomography revealed the solid mass between the stomach and pancreas corpus and tail, possibly orginating from the pancreas. With the preoperative diagnosis of locally invasive distal pancreas cancer the patient underwent laparotomy, following the dissection, the mass was observed to be originating from the posterior gastric Wall, extending exophytically with a peduncle of 5 cm in width, without any visual evidence for peritoneal invasion and metastasis. The tumour and the peduncle was resected with stapler device. Total operation time was 30 min. Postoperative course was uneventful. Pathologic diagnosis was gastrointestinal stromal tumour (GIST). DISCUSSION Pedunculated large GISTs are not frequent and they can enlarge as 15 cm in diameter and compress the neighbouring organs. When they were huge, it is difficult to differentiate the origin of the masses. GISTs should be considered in differential diagnosis of giant abdominal masses. CONCLUSION When GISTs are huge and pedunculated, it can be difficult to differentiate the origin of the masses. This case report presents unexpectedly ease surgery for a worrysome abdominal mass.

    Full Text Available Bezoar is a mass that cannot be digested and that is collected in the gastrointestinal system. Being the exact frequency still unknown; it is rare among children. Trichobezoar is especially encountered in young adolescent girls who have psychiatric/neurologic problems. In this report; a fifteen year old girl who has stomachache and vomiting is presented. A mass without pain on palpation was diagnosed as trichobezoar by performing an endoscopy. A mass which weighed 1.5 kilograms and which took the shape of the stomach was removed out of her stomach by laparatomy. On her psychiatric examination; she was diagnosed with mild mental retardation and obsessive compulsive disorder. Trichobezoar should be considered when adolescent girls with psychiatric problems come with gastrointestinal symptoms such as stomachache and vomiting.

  11. Charm mass effects in bulk channel correlations

    CERN Document Server

    Burnier, Y

    2013-01-01

    The bulk viscosity of thermalized QCD matter at temperatures above a few hundred MeV could be significantly influenced by charm quarks because their contribution arises four perturbative orders before purely gluonic effects. In an attempt to clarify the challenges of a lattice study, we determine the relevant imaginary-time correlator (of massive scalar densities) up to NLO in perturbation theory, and compare with existing data. We find discrepancies much larger than in the vector channel; this may hint, apart from the importance of taking a continuum limit, to larger non-perturbative effects in the scalar channel. We also recall how a transport peak related to the scalar density spectral function encodes non-perturbative information concerning the charm quark chemical equilibration rate close to equilibrium.

    2012-01-01

    Full Text Available Aimed at portable application, a new integrated process chip for thin film bulk acoustic resonator (FBAR mass sensor is proposed and verified with 0.18 um CMOS processing in this paper. The longitudinal mode FBAR with back-etched structure is fabricated, which has resonant frequency 1.878 GHz and factor 1200. The FBAR oscillator, based on the current-reuse structure, is designed with Modified Butterworth Van Dyke (MBVD model. The result shows that the FBAR oscillator operates at 1.878 GHz with a phase noise of −107 dBc/Hz and −135 dBc/Hz at 10 KHz and 100 KHz frequency offset, respectively. The whole process chip size with pads is 1300 μm × 950 μm. The FBAR and process chip are bonded together to sense tiny mass. The measurement results show that this chip precision is 1 KHz with the FBAR frequency gap from 25 kHz to 25 MHz.

    Abdominal actinomycosis is a rare disorder. The diagnosis is frequently missed preoperatively. We describe a patient who had had an intrauterine contraceptive device in situ for 5 years. She presented with a painful pelvicoabdominal mass, located between the uterus and rectum, and a colitis-like disease of the distal colon. Culture of the removed IUD demonstrated Actinomyces. She was intensively treated with intravenously penicillin for six weeks. Following this conservative treatment the abdominal tumor and the colitis-like symptoms totally disappeared. During two years follow-up she is free of symptoms and no signs of recurrence of the disease have been noticed. The case described here strongly underlines that Actinomyces infection should be born in mind in the differential diagnosis of a young female with an IUD, presenting with colitis, fever and an abdominal mass. Prolonged intravenously administered penicillin is warranted before surgery should be considered.

    2006-08-01

    A 42-year-old woman who complained of epigastralgia was referred to our hospital because of an abdominal mass found by ultrasonography. CT and MRI scans revealed that the abdominal mass, 4 cm in diameter, located on the left side of the right kidney. Gastroduodenoscopy detected a deep ulcerative lesion covered with a yellowish coat in the second portion of duodenum. A sonolucent area at the bottom of the ulcerative lesion seemed to expand to the abdominal mass on ultrasonic endoscopy. Tuberculosis was one possible differential diagnosis. Pathological examination including Ziehl-Neelsen staining using biopsy specimens taken from the bottom of the ulcerative lesion did not show tuberculosis infection. However, polymerase chain reaction analysis using the biopsy specimens revealed that gene expression of tuberculosis was positive. We determined that tuberculous lymphadenitis penetrated the duodenum forming an ulcerative lesion in the duodenum. The administration of anti-tubercular medicine for 6 months male the abdominal mass disappeared and the duodenal ulcerative lesion formed an ulcer scar. We report here a case of tuberculous lymphadenitis penetrating the duodenum which was successfully treated by conservative therapy without surgical treatment.

    2016-01-01

    Full Text Available The authors present the clinical case of a 14-year old girl with weight loss, anorexia, epigastric abdominal pain and postprandial vomiting with 5 months duration. There was a background of trichophagia for 2 years without evidence of alopecia or psychiatric history. The physical examination revealed an epigastric mass motionless, stony, with poorly defined limits, painful on palpation and about 7 cm diameter. Abdominal ultrasonography showed thickening of the gastric wall and antrum with gastric distension. The abdominal tomography scan and endoscopic examination revealed the presence of a bulky trichobezoar occupying almost the entire gastric lumen. It was decided to undergo gastrotomy and extraction of the bezoar. The postoperative period was uneventful.

  3. The relationship of abdominal fat mass assessed by helical or conventional computed tomography to serum leptin concentration.

    Kobayashi, Junji; Sasaki, Takeyoshi; Watanabe, Mitsuyo

    2004-01-01

    In the present study, we focused on the relationship of intra-abdominal visceral fat (VF) or subcutaneous fat (SF) mass to serum leptin levels, and also on the relationship of leptin to serum lipid and lipoprotein concentration. Subjects with obesity (26 men, 26 women) were recruited for this study. We obtained helical CT scans with a tube current of 150 mA, voltage of 120 kV and 2:1 pitch (table speed in relation to slice thickness), starting at the upper edge of the liver and continuing to the pelvis. The intra-abdominal visceral fat (VF) volume was measured by drawing a line within the muscle wall surrounding the abdominal cavity. The abdominal SF volume was calculated by subtracting the VF volume from the total abdominal fat volume. By comparison, the abdominal VF and SF areas were determined at the umbilical level by the established slice-by-slice CT scanning technique. We found: 1) abdominal SF mass, either as volume or area, was a more important determinant of serum leptin than was VF mass; 2) among TC, TG, HDL-C and LDL-C, only TG had a positive correlation to serum leptin levels in men, whereas in women no lipid parameters had any relationship with leptin; and 3) VF mass had a positive correlation to serum TC and TG in men, whereas SF did not. The present study provides considerable evidence on the relationship between abdominal fat mass and serum leptin, and shows that the relationships between serum leptin and serum lipids and lipoproteins are not straightforward. We also suggest that fat area measured by conventional CT is a better indicator than its corresponding volume assessed by helical CT, based on the present results showing its closer association to serum lipids.

    We have studied the bulk viscosity of strange quark matter in the density dependent quark mass model (DDQM) and compared results with calculations done earlier in the MIT bag model where , masses were neglected and first order interactions were taken into account. We find that at low temperatures and high relative perturbations, the bulk viscosity is higher by 2 to 3 orders of magnitude while at low perturbations the enhancement is by 1–2 order of magnitude as compared to earlier results. Also the damping time is 2–3 orders of magnitude lower implying that the star reaches stability much earlier than in MIT bag model calculations.

    2016-05-01

    Full Text Available Amongst the varied, diverse causes of intraabdominal masses in infancy and early childhood, gastric teratomas (GTs account for a very small proportion. A worldwide literature search reveals only around one hundred cases of GT and also supports the fact that its preoperative diagnosis remains elusive. Here we report the case of a two-month-old male who presented to the pediatric surgery outpatient department of Kasturba Medical College and Hospital, Karnataka, India, with progressive distension of abdomen since birth. Clinically, a large firm, non-mobile and non-tender mass involving all four quadrants of the abdomen was seen. Ultrasound revealed a large solid-cystic mass with internal septations extending from the epigastrium up to the pelvis. Computed tomography revealed a large intraperitoneal fat containing solid-cystic mass lesion showing curvilinear and chunky areas of calcification, with the mass focally indenting the posterior gastric wall and showing focal polypoidal intragastric extension. Exploratory laparotomy revealed a large cystic tumor with a solid component, arising from lesser curvature of the stomach, showing focal intraluminal extension across the posterior gastric wall, and occupying the whole lesser sac and abdominal cavity. The tumor was excised in toto along with the body of the stomach. Histopathological examination showed mature tissue derived from all three germ cell layers and confirmed the diagnosis of mature gastric teratoma. The patient was disease free at one-year follow-up.

    2016-01-01

    Malignant fibrous histiocytoma (MFH) is a rare tumor that mostly involves adults aged 50 to 70. The most common anatomic location is the lower extremities. MFH of the retroperitoneum usually manifests late in its course and may be initially mistaken with other more common diagnosis. Here, the authors describe a 60-year-old man that was brought to the emergency department with a chief complaint of periumbilical abdominal pain. Our patient presented with symptoms consistent with a symptomatic aortic aneurysm, but a mass was encountered during surgery. In such circumstances the diagnosis of malignant sarcoma must be kept in mind and attempts at full resection with tumor-free margins are necessary. PMID:27563479

  9. Effects of Mass Fluctuation on Thermal Transport Properties in Bulk Bi2Te3

    Science.gov (United States)

    Huang, Ben; Zhai, Pengcheng; Yang, Xuqiu; Li, Guodong

    2016-10-01

    In this paper, we applied large-scale molecular dynamics and lattice dynamics to study the influence of mass fluctuation on thermal transport properties in bulk Bi2Te3, namely thermal conductivity (K), phonon density of state (PDOS), group velocity (v g), and mean free path (l). The results show that total atomic mass change can affect the relevant vibrational frequency on the micro level and heat transfer rate in the macro statistic, hence leading to the strength variation of the anharmonic phonon processes (Umklapp scattering) in the defect-free Bi2Te3 bulk. Moreover, it is interesting to find that the anharmonicity of Bi2Te3 can be also influenced by atomic differences of the structure such as the mass distribution in the primitive cell. Considering the asymmetry of the crystal structure and interatomic forces, it can be concluded by phonon frequency, lifetime, and velocity calculation that acoustic-optical phonon scattering shows the structure-sensitivity to the mass distribution and complicates the heat transfer mechanism, hence resulting in the low lattice thermal conductivity of Bi2Te3. This study is helpful for designing the material with tailored thermal conductivity via atomic substitution.

  10. Bulk soybean grain mass temperature in warehouses with isolated vents and vent-exhaust combined systems

    Eliza Rigoni de Pontes

    Full Text Available ABSTRACT: This study aimed to compare the temperatures in the mass of bulk soybeans ( Glycine max in warehouses with isolated vents and vent-combined exhaustion. A completely randomized design was used, with two treatments and ten repetitions. Treatments consisted of warehouse with curved vents and warehouse with curved + static exhaust vents. Each repetition contained the average of all readings in three days in all cables of the warehouse part under study, totaling 10 repetitions per month. The variable analyzed was the temperature in the grain mass in the lower, middle and upper parts of the warehouse from January to May 2012. The environment temperature and humidity were also registered. Static hoods, along with curved vents on the roof of the warehouse showed a tendency to reduce the temperature of the soybean mass with decrease in environmental temperature and increase in relative environmental humidity.

  11. The respective roles of bulk friction and slip velocity during a granular mass flow

    2016-04-01

    Catastrophic granular mass flows form an important natural hazard. Mitigation has motivated numerous studies on the properties of natural granular flows, and in particular, their ability to travel long distances away from the release point. The mobility of granular flows is commonly characterised through the definition of rheological properties and effective friction. Yet, it is widely accepted that the description in term of effective friction may include various lubrication effects, softening at the base of the flow and large slip velocities being a most likely one. In this case, flow bulk properties may obliterate the flow boundary conditions. In this contribution, we investigate how disentangling bulk properties from boundary conditions may improve our understanding of the flow. Using discrete simulations, we induce increasing slip velocities in different flow configurations. We show that increased mobility may be achieved without changing bulk properties. The results are interpreted in terms of a Robin-Navier slip condition and implemented in a continuum Navier-Stokes solver. We quantify the respective role of rheological bulk properties and boundary conditions in the general behaviour of a transient mass flow. We show that omitting the description of boundary conditions leads to misinterpretation of the flow properties. The outcome is discussed in terms of models reliability. References P.-Y.

    Zeng, H C; Chen, H J; Zhai, S L; Zhao, X P

    2012-01-01

    We experimentally constructed a three-dimensional flute-model "molecular" structure acoustic metamaterial(AM)from a periodic array of perforated hollow steel tubes (PHSTs) and investigated its transmission and reflection behaviors in impedance tube system. The AM exhibited a transmission peak and an inverse phase, thus exhibiting the local resonance of the PHSTs. Based on the homogeneous media theory, the effective bulk modulus and mass density of the AM were calculated to be simultaneously negative; the refractive index was also negative. PHST AM slab focusing experiments showed that the medium with a resonant structure exhibited a distinct metamaterial property.

    Mass density, dielectric, elastic, and piezoelectric constants of bulk GaN crystal were determined. Mass density was obtained from the measured ratio of mass to volume of a cuboid. The dielectric constants were determined from the measured capacitances of an interdigital transducer (IDT) deposited on a Z-cut plate and from a parallel plate capacitor fabricated from this plate. The elastic and piezoelectric constants were determined by comparing the measured and calculated SAW velocities and electromechanical coupling coefficients on the Z- and X-cut plates. The following new constants were obtained: mass density p = 5986 kg/m(3); relative dielectric constants (at constant strain S) ε(S)(11)/ε(0) = 8.6 and ε(S)(11)/ε(0) = 10.5, where ε(0) is a dielectric constant of free space; elastic constants (at constant electric field E) C(E)(11) = 349.7, C(E)(12) = 128.1, C(E)(13) = 129.4, C(E)(33) = 430.3, and C(E)(44) = 96.5 GPa; and piezoelectric constants e(33) = 0.84, e(31) = -0.47, and e(15) = -0.41 C/m(2).

    Quantifying crustal deformation is important for evaluating mass balance, material transfer, and the interplay between tectonism and magmatism in continental arcs. We present a dataset of >650 finite strain analyses compiled from published works and our own studies with associated structural, geochronologic, and geobarometric information in central and southern Sierra Nevada, California, to quantify the arc crust deformation. Our results show that Mesozoic tectonism results in 65% arc-perpendicular bulk crust shortening under a more or less plane strain condition. Mesozoic arc magmatism replaced ∼80% of this actively deforming arc crust with plutons requiring significantly greater crustal thickening. We suggest that by ∼85 Ma, the arc crust thickness was ∼80 km with a 30-km-thick arc root, resulting in a ∼5 km elevation. Most tectonic shortening and magma emplacement must be accommodated by downward displacements of crustal materials into growing crustal roots at the estimated downward transfer rate of 2-13 km/Myr. The downward transfer of crustal materials must occur in active magma channels, or in "escape channels" in between solidified plutons that decrease in size with time and depth resulting in an increase in the intensity of constrictional strain with depth. We argue that both tectonism and magmatism control the thickness of the crust and surface elevation with slight modification by surface erosion. The downward transported crustal materials initially fertilize the MASH zone thus enhancing to the generation of additional magmas. As the crustal root grows it may potentially pinch out and cool the mantle wedge and thus cause reduction of arc magmatism.

  1. A review of the theoretical basis for bulk mass flux convective parameterization

    Directory of Open Access Journals (Sweden)

    2010-04-01

    Full Text Available Most parameterizations for precipitating convection in use today are bulk schemes, in which an ensemble of cumulus elements with different properties is modelled as a single, representative entraining-detraining plume. We review the underpinning mathematical model for such parameterizations, in particular by comparing it with spectral models in which elements are not combined into the representative plume. The chief merit of a bulk model is that the representative plume can be described by an equation set with the same structure as that which describes each element in a spectral model. The equivalence relies on an ansatz for detrained condensate introduced by Yanai et al. (1973 and on a simplified microphysics. There are also conceptual differences in the closure of bulk and spectral parameterizations. In particular, we show that the convective quasi-equilibrium closure of Arakawa and Schubert (1974 for spectral parameterizations cannot be carried over to a bulk parameterization in a straightforward way. Quasi-equilibrium of the cloud work function assumes a timescale separation between a slow forcing process and a rapid convective response. But, for the natural bulk analogue to the cloud-work function, the relevant forcing is characterised by a different timescale, and so its quasi-equilibrium entails a different physical constraint. Closures of bulk parameterizations that use a parcel value of CAPE do not suffer from this timescale issue. However, the Yanai et al. (1973 ansatz must be invoked as a necessary ingredient of those closures.

    To evaluate the sensitivity and specificity of body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) measurements in diagnosing abdominal visceral obesity. Methods BMI, WC, and WHR were assessed in 690 Chinese adults (305 men and 385women) and compared with magnetic resonance imaging (MRI) measurements of abdominal visceral adipose tissue (VA). Receiver operating characteristic (ROC) curves were generated and used to determine the threshold point for each anthropometric parameter. Results 1) MRI showed that 61.7% of overweight/obese individuals (BMI≥25 kg/m2) and 14.2% of normal weight (BMI<25kg/m2) individuals had abdominal visceral obesity (VA≥ 100 cm2). 2) VA was positively correlated with each anthropometric variable, of which WC showed the highest correlation (r=0.73-0.77,P<0.001 ). 3) The best cut-off points for assessing abdominal visceral obesity were as followed: BMI of 26 kg/m2, WC of 90 cm, and WHR of 0.93, with WC being the most sensitive and specific factor. 4)Among subjects with BMI≥28 kg/m2 or WC≥95 cm, 95% of men and 90% of women appeared to have abdominal visceral obesity. Conclusion Measurements of BMI, WC, and WHR can be used in the prediction of abdominal visceral obesity, of which WC was the one with better accuracy.

    Image-guided percutaneous biopsy of abdominal masses is among the most commonly performed procedures in interventional radiology. While most abdominal masses are readily amenable to percutaneous biopsy, some may be technically challenging for a number of reasons. Low lesion conspicuity, small size, overlying or intervening structures, motion, such as that due to respiration, are some of the factors that can influence the ability and ultimately the success of an abdominal biopsy. Various techniques or technologies, such as choice of imaging modality, use of intravenous contrast and anatomic landmarks, patient positioning, organ displacement or trans-organ approach, angling CT gantry, triangulation method, real-time guidance with CT fluoroscopy or ultrasound, sedation or breath-hold, pre-procedural image fusion, electromagnetic tracking, and others, when used singularly or in combination, can overcome these challenges to facilitate needle placement in abdominal masses that otherwise would be considered not amenable to percutaneous biopsy. Familiarity and awareness of these techniques allows the interventional radiologist to expand the use of percutaneous biopsy in clinical practice, and help choose the most appropriate technique for a particular patient.

    Full Text Available We applied hierarchical cluster analysis to an Aerodyne aerosol mass spectrometer (AMS bulk mass spectral dataset collected aboard the NOAA research vessel Ronald H. Brown during the 2002 New England Air Quality Study off the east coast of the United States. Emphasizing the organic peaks, the cluster analysis yielded a series of categories that are distinguishable with respect to their mass spectra and their occurrence as a function of time. The differences between the categories mainly arise from relative intensity changes rather than from the presence or absence of specific peaks. The most frequent category exhibits a strong signal at m/z 44 and represents oxidized organic matter most probably originating from both, anthropogenic as well as biogenic sources. On the basis of spectral and trace gas correlations, the second most common category with strong signals at m/z 29, 43, and 44 contains contributions from isoprene oxidation products. The third through the fifth most common categories have peak patterns characteristic of monoterpene oxidation products and were most frequently observed when air masses from monoterpene rich regions were sampled. Taken together, the second through the fifth most common categories represent as much as 5 µg/m3 organic aerosol mass – 17% of the total organic mass – that can be attributed to biogenic sources. These numbers have to be viewed as lower limits since the most common category was attributed to anthropogenic sources for this calculation. The cluster analysis was also very effective in identifying a few contaminated mass spectra that were not removed during pre-processing. This study demonstrates that hierarchical clustering is a useful tool to analyze the complex patterns of the organic peaks in bulk aerosol mass spectra from a field study.

    Endometriosis of abdominal wall scar following operation on uterus and tubes is extremely rare. The late onset of symptoms after surgery is the usual cause of misdiagnosis. Scar endometriosis is a rare disease which is difficult to diagnose and should always be considered as a differential diagnosis of painful abdominal masses in women. The diagnosis is made only after excision and histopathology of the lesion. Preoperative differentials include hernia, lipoma, suture granuloma or abscess. Hence an awareness of the entity avoids delay in diagnosis, helps clinicians to a more tailored treatment and also avoids unnecessary referrals. We report a case of abdominal endometriosis. The definitive diagnosis of which was established by histopathological studies.

    A new method for bulk carbon isotope ratio determination of water-soluble samples is presented that is based on flow injection analysis-isotope ratio mass spectrometry (FIA-IRMS) using an LC IsoLink interface. Advantages of the method are that (i) only very small amounts of sample are required (2-5 microL of the sample for up to 200 possible injections), (ii) it avoids complex sample preparation procedures such as needed for EA-IRMS analysis (only sample dilution and injection,) and (iii) high throughput due to short analysis times is possible (approximately 15 min for five replicates). The method was first tested and evaluated as a fast screening method with industrially produced ethanol samples, and additionally the applicability was tested by the measurement of 81 alcoholic beverages, for example, whiskey, brandy, vodka, tequila, and others. The minimal sample concentration required for precise and reproducible measurements was around 50 microL L(-1) ethanol/water (1.71 mM carbon). The limit of repeatability was determined to be r=0.49%. FIA-IRMS represents a fast screening method for beverage authenticity control. Due to this, samples can be prescreened as a decisive criterion for more detailed investigations by HPLC-IRMS or multielement GC-IRMS measurements for a verification of adulteration.

    Intra-abdominal and extraperitoneal actinomycosis are rare infections, caused by different Actinomyces species. However, they have been diagnosed more frequently in the last ten years. We report three cases of abdominal actinomycosis and a literature review of the last eight years. All three patients were diagnosed by means of histopathologic examination only. In one case, an intrauterine device (IUD) was associated with the infection. Therapy consisted of surgical resection of the inflammatory, infected tissue, and long-term antibiotic therapy. All patients are free of recurrence. Abdominal actinomycosis should be included in the differential diagnosis of an abdominal pathology of insidious onset, especially when an IUD is in place. Even when infection had spread extensively, combined operative and antibiotic therapy cured most of the cases.

    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

    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.

  16. Successful treatment of a free-moving abdominal mass with radiation therapy guided by cone-beam computed tomography: a case report

    Directory of Open Access Journals (Sweden)

    Shihadeh Ferial

    2010-10-01

    Full Text Available Abstract Introduction Because tumors in the abdomen can change position, targeting these tumors for radiation therapy should be done with caution; use of daily image-guided radiation therapy is advised. Case presentation We report the case of a 72-year-old Caucasian man with recurrent mantle cell lymphoma who was referred for palliative radiation therapy for an abdominopelvic tumor. Computed tomography was used to generate images for radiation treatment planning. Comparison of those planning images with a positron emission tomography/computed tomography scan ordered during the planning period revealed that the tumor had moved from one side of the abdomen to the other during the three-day interval between scans. To account for this unusual tumor movement, we obtained a second set of planning computed tomography scans and used a Varian cone-beam computed tomography scanner with on-board imaging capability to target the tumor before each daily treatment session, leading to successful treatment and complete resolution of the mass. Conclusion Abdominal masses associated with the mesentery should be considered highly mobile; thus, radiation therapy for such masses should be used with the utmost caution. Modern radiation therapy techniques offer the ability to verify the tumor location in real time and shift the treatment ports accordingly over the course of treatment.

The active independent variable investigated was nature of treatment intervention (Pilates mat based exercises vs resistance exercise, and the dependent variables were hs-CRP level, AC and BMI. The statistical analysis used Wilcoxon signed rank and Mann-Whitney tests. The correlation between the continuous variables was assessed using Spearman’s coefficient of correlation. The data were analysed using SPSS software version 17.0, and probability values lower than 5% (p< 0.05 were considered statistically significant. Mat Pilates based exercises exhibited reductions in serum hs-CPR level (Wilcoxon signed rank test; z = -2.466, p = 0.01, BMI (Wilcoxon signed rank test; z = -3.295, p = 0.001 and AC (Wilcoxon signed rank test; z = -3.398, p = 0.01. Mat Pilates based exercises promoted a significant reduction of the serum hs-CRP levels and anthropometric measurements in elderly individuals.

    Full Text Available The sagittal abdominal diameter (SAD measured in supine position is an alternative adiposity indicator that estimates the quantity of dysfunctional adipose tissue in the visceral depot. However, supine SAD's distribution and its association with health risk at the population level are unknown. Here we describe standardized measurements of SAD, provide the first, national estimates of the SAD distribution among US adults, and test associations of SAD and other adiposity indicators with prevalent dysglycemia.In the 2011-2012 National Health and Nutrition Examination Survey, supine SAD was measured ("abdominal height" between arms of a sliding-beam caliper at the level of the iliac crests. From 4817 non-pregnant adults (age ≥ 20; response rate 88% we used sample weights to estimate SAD's population distribution by sex and age groups. SAD's population mean was 22.5 cm [95% confidence interval 22.2-22.8]; median was 21.9 cm [21.6-22.4]. The mean and median values of SAD were greater for men than women. For the subpopulation without diagnosed diabetes, we compared the abilities of SAD, waist circumference (WC, and body mass index (BMI, kg/m(2 to identify prevalent dysglycemia (HbA1c ≥ 5.7%. For age-adjusted, logistic-regression models in which sex-specific quartiles of SAD were considered simultaneously with quartiles of either WC or BMI, only SAD quartiles 3 (p<0.05 vs quartile 1 and 4 (p<0.001 vs quartile 1 remained associated with increased dysglycemia. Based on continuous adiposity indicators, analyses of the area under the receiver operating characteristic curve (AUC indicated that the dysglycemia model fit for SAD (age-adjusted was 0.734 for men (greater than the AUC for WC, p<0.001 and 0.764 for women (greater than the AUC for WC or BMI, p<0.001.Measured inexpensively by bedside caliper, SAD was associated with dysglycemia independently of WC or BMI. Standardized SAD measurements may enhance assessment of dysfunctional adiposity.

    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.

  3. Comet formation in collapsing pebble clouds. What cometary bulk density implies for the cloud mass and dust-to-ice ratio

    Lorek, S; Lacerda, P; Blum, J

    2016-01-01

    Comets are remnants of the icy planetesimals that formed beyond the ice line in the Solar Nebula. Growing from micrometre-sized dust and ice particles to km-sized objects is, however, difficult because of growth barriers and time scale constraints. The gravitational collapse of pebble clouds that formed through the streaming instability may provide a suitable mechanism for comet formation. We study the collisional compression of cm-sized porous ice/dust-mixed pebbles in collapsing pebble clouds. For this, we developed a collision model for pebbles consisting of a mixture of ice and dust, characterised by their dust-to-ice mass ratio. Using the final compression of the pebbles, we constrain combinations of initial cloud mass, initial pepple porosity, and dust-to-ice ratio that lead to cometesimals which are consistent with observed bulk properties of cometary nuclei. We find that observed high porosity and low density of ~0.5 g/cc of comet nuclei can only be explained if comets formed in clouds with mass appro...

    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.

    2015-01-01

    A 52-year-old Hispanic woman presented to the emergency department, reporting worsening sharp lower right quadrant abdominal pain for 3 days. CT of the abdomen and pelvis showed evidence of inflammation in the peritoneal soft tissues adjacent to an enlarged and thick-walled appendix, an appendicolith, no abscess formation and a slightly thickened caecum consistent with acute appendicitis. During laparoscopic appendectomy, the caecum was noted to be firm, raising suspicion of malignancy. Surgical oncology team was consulted and open laparotomy with right hemicolectomy was performed. Pathology reported that the ileocaecal mass was not a malignancy but was, rather, actinomycosis. The patient was discharged after 10 days of intravenous antibiotics in the hospital, with the diagnosis of abdominal actinomycosis. Although the original clinical and radiological findings in this case were highly suggestive of acute appendicitis, abdominal actinomycosis should be in the differential for right lower quadrant pain as it may be treated non-operatively.

    Abdominal pregnancies are the implantation of gestation in some of the abdominal structures. This kind of pregnancies represents sevenfold maternal death risk than tubarian ectopic pregnancies, and 90-fold death risk than normal ones. Previous cases have erroneously reported as abscess in Douglas punch, and frequently result in obitus or postnatal deaths. We report a case of a patient with 27 years old, and diagnosis of 25.2 weeks of pregnancy, prior placenta and anhidramnios, referred due to difficult in uterine contour delimitation, easy palpation of fetal parts, cephalic pole in left hypochondrious and presence of mass in hypogastria, no delimitations, pain with mobilization, no transvaginal bleed and fetal movements. Interruption of pregnancy is decided by virtue of severe oligohidramnios, retardation in fetal intrabdominal growth, and recurrent maternal abdominal pain. Surgical intervention was carried out for resolution of the obstetrical event, in which was found ectopic abdominal pregnancy with bed placental in right uterine horn that corresponded to a pregnancy of 30 weeks of gestation. Abdominal pregnancy is still a challenge for obstetrics due to its diagnosis and treatment. Early diagnosis is oriented to prevent an intrabdominal hemorrhage that is the main maternal cause of mortality.

    Highlights: • Analysis of estrogens in small volume samples at low parts-per-trillion concentration. • Charged bulk derivatization facilitates on-line ion exchange sample preparation. • On-line WCX restricted access media traps analytes, but not proteins and lipids. • Complete preparation and LC–MS/MS analysis completed in 30 min/sample. - Abstract: Estrone (E1), estradiols (α/β-E2), and estriol (E3) are four major metabolically active estrogens exerting strong biological activities at very low circulating concentrations. This paper reports a sensitive and efficient method with automated, on-line clean-up and detection to determine trace estrogens in a small volume of serum samples using liquid chromatography–electrospray ionization–tandem mass spectrometry directly, without off-line liquid–liquid or solid-phase extraction pretreatments. Serum aliquots (charcoal stripped fetal bovine serum, 100 μL) were spiked with four estrogen standards and their corresponding isotope-labeled internal standards, then bulk derivatized with 2-fluoro-1-methyl-pyridium p-toluenesulfonate (2-FMP) to establish the calibration curves and perform method validation. Calibration was established in the concentration ranges of 5–1000 pg mL{sup −1}, and demonstrated good linearity of R{sup 2} from 0.9944 to 0.9997 for the four derivatized estrogens. The lower detection limits obtained were 3–7 pg mL{sup −1}. Good accuracy and precision in the range of 86–112% and 2.3–11.9%, respectively, were observed for the quality control (QC) samples at low, medium, and high concentration levels. The stability tests showed that the derivatized serum samples were stable 8 h after derivatization at room temperature and at least to 48 h if stored at −20 °C. The method was applied to measure trace estrogens in real human and bovine serum samples, and three of four estrogen compounds studied were observed and quantified.

    Full Text Available Background: Abdominal epilepsy (AE is an uncommon cause for chronic recurrent abdominal pain in children and adults. It is characterized by paroxysmal episode of abdominal pain, diverse abdominal complaints, definite electroencephalogram (EEG abnormalities and favorable response to the introduction of anti-epileptic drugs (AED. We studied 150 children with chronic recurrent abdominal pain and after exclusion of more common etiologies for the presenting complaints; workup proceeded with an EEG. We found 111 (74% children with an abnormal EEG and 39 (26% children with normal EEG. All children were subjected to AED (Oxcarbazepine and 139 (92% children responded to AED out of which 111 (74% children had an abnormal EEG and 27 (18% had a normal EEG. On further follow-up the patients were symptom free, which helped us to confirm the clinical diagnosis. Context: Recurrent chronic abdominal pain is a common problem encountered by pediatricians. Variety of investigations are done to come to a diagnosis but a cause is rarely found. In such children diagnosis of AE should be considered and an EEG will confirm the diagnosis and treated with AED. Aims: To find the incidence of AE in children presenting with chronic recurrent abdominal pain and to correlate EEG findings and their clinical response to empirical AEDs in both cases and control. Settings and Design: Krishna Institute of Medical Sciences University, Karad, Maharashtra, India. Prospective analytical study. Materials and Methods: A total of 150 children with chronic recurrent abdominal pain were studied by investigations to rule out common causes of abdominal pain and an EEG. All children were then started with AED oxycarbamezepine and their response to the treatment was noted. Results: 111 (74% of the total 150 children showed a positive EEG change suggestive of epileptogenic activity and of which 75 (67.56% were females and 36 (32.43% were male, majority of children were in the age of group of 9

    Full Text Available Abdominal compartment syndrome (ACS increases the risk for mortality in critically ill children. It occurs in association with a wide variety of medical and surgical diagnoses. Management of ACS involves recognizing the development of intra-abdominal hypertension (IAH by intra-abdominal pressure (IAP monitoring, treating the underlying cause, and preventing progression to ACS by lowering IAP. When ACS is already present, supporting dysfunctional organs and decreasing IAP to prevent new organ involvement become an additional focus of therapy. Medical management strategies to achieve these goals should be employed but when medical management fails, timely abdominal decompression is essential to reduce the risk of mortality. A literature review was performed to understand the role and outcomes of abdominal decompression among children with ACS. Abdominal decompression appears to have a positive effect on patient survival. However, prospective randomized studies are needed to fully understand the indications and impact of these therapies on survival in children.

    Necrotizing fasciitis is a critical illness involving skin and soft tissues, which may develop after blunt abdominal trauma causing abdominal wall hernia and representing a great challenge for physicians. A 52-year-old man was brought to the emergency department after a road accident, presenting blunt abdominal trauma with a large non-reducible mass in the lower-right abdomen. A first, CT showed abdominal hernia without signs of complication. Three hours after ICU admission, he developed hemodynamic instability. Therefore, a new CT scan was requested, showing signs of hernia complication. He was moved to the operating room where a complete transversal section of an ileal loop was identified. Five hours after surgery, he presented a new episode of hemodynamic instability with signs of skin and soft tissue infection. Due to the high clinical suspicion of necrotizing fasciitis development, wide debridement was performed. Following traumatic abdominal wall hernia (TAWH), patients can present unsuspected injuries in abdominal organs. Helical CT can be falsely negative in the early moments, leading to misdiagnosis. Necrotizing fasciitis is a potentially fatal infection and, consequently, resuscitation measures, wide-spectrum antibiotics, and early surgical debridement are required. This type of fasciitis can develop after blunt abdominal trauma following wall hernia without skin disruption.

    Approximately 10 per cent of abdominal aneurysms have an excessively thick wall that sometimes involve duodenum, cava or colon by an inflammatory process. Between February 1986 and December 1992, 147 patients with abdominal aortic aneurysm (AAA) were treated surgically and in 13 (8.8%) the aneurysms were found to be inflammatory. Their mean age was 67.3 years (70.1 years in non inflammatory group) and all were symptomatics initially (abdominal pain in 53%, rupture in 23%, mass in 15%). The operative mortality for elective resection was 37% in patients with inflammatory abdominal aortic aneurysms (IAAA) decreasing to 9% in the AAA group without inflammatory involvement. We conclude that surgery is indicated in these patients to prevent rupture and to hasten the subsidense of inflammatory process ever with postoperative morbi-mortality increased.

    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.

    Recent experimental results from the LHC have placed strong constraints on the masses of colored superpartners. The MSSM parameter space is also constrained by the measurement of the Higgs boson mass, and the requirement that the relic density of lightest neutralinos be consistent with observations. Although large regions of the MSSM parameter space can be excluded by these combined bounds, leptophilic versions of the MSSM can survive these constraints. In this paper we consider a scenario in which the requirements of minimal flavor violation, vanishing $CP$-violation, and mass universality are relaxed, specifically focusing on scenarios with light sleptons. We find a large region of parameter space, analogous to the original bulk region, for which the lightest neutralino is a thermal relic with an abundance consistent with that of dark matter. We find that these leptophilic models are constrained by measurements of the magnetic and electric dipole moments of the electron and muon, and that these models have ...

    The reported incidence of inflammatory abdominal aortic aneurysm (IAAA) is from 2% to 14% of patients with abdominal aortic aneurysm and the etiology of this disease is still discussed--according to the literature several pathogenic theories have been proposed. From 1992 to 1997 32 patients with IAAA were operated on. The patients were mostly symptomatic--abdominal pain was present in 68.75% cases, back pain in 31.25%, fever in 12.5% and weight loss in 6.25% of the operated patients. In all the patients ultrasound examination was performed, in 4 patients CT and in 3 cases urography. All the patients were operated on and characteristic signs of inflammatory abdominal aortic aneurysm like: thickened aortic wall, perianeurysmal infiltration or retroperitoneal fibrosis with involvement of retroperitoneal structures were found. In all cases surgery was performed using transperitoneal approach; in three cases intraoperatively contiguous abdominal organs were injured, which was connected with their involvement into periaortic inflammation. In 4 cases clamping of the aorta was done at the level of the diaphragmatic hiatus. 3 patients (9.37%) died (one patient with ruptured abdominal aortic aneurysm). Authors present diagnostic procedures and the differences in the surgical tactic, emphasizing the necessity of the surgical therapy in patients with inflammatory abdominal aortic aneurysm.

    2013-01-01

    Full Text Available Background. Desmoids are benign tumors, with local invasive features and no metastatic potential, which have rarely been described to be pregnancy associated. Case. We described the rapid growth of an anterior abdominal wall mass in a 40-year-old pregnant woman. Due to its close proximity to the enlarged uterus, it was misdiagnosed to be a uterine leiomyoma by ultrasound examination. Final tissue diagnosis and radical resection were done at the time of abdominal delivery. Conclusion. Due to the diagnostic limitations of imaging techniques, desmoids should always be considered when the following manifestations are observed in combination: progressive growth of a solitary abdominal wall mass during pregnancy and well-delineated smooth tumor margins demonstrated by imaging techniques. This case emphasizes the importance of entertaining uncommon medical conditions in the differential diagnosis of seemingly common clinical manifestations.

    Full Text Available Background: We explored the relationship between anthropometric indices (obesity and abdominal adiposity and the presence of an atherogenic lipid profile in Nigerians with major cardiovascular risk factors (type 2 diabetes mellitus-T2DM, hypertension-HBP, and concomitant disease. Materials and Methods: Using a prospective design, 278 patients with T2DM, HBP, or concomitant disease, attending out-patient diabetes and hypertension clinics at a tertiary institution in Nigeria were evaluated. All patients were cholesterol-lowering oral medication naοve. Demographic and clinical data and anthropometric measurements were documented. Fasting lipid profiles were measured in all cases. The cut-off points for defining dyslipidaemia were: Elevated total cholesterol (TC (mg/dL ≥200, elevated low-density lipoprotein cholestrol (LDL-C (mg/dL ≥100, low high-density lipoprotein cholesterol (HDL-C (mg/dL <40 for men and <50 for women, and high triglycerides (TG (mg/dL ≥150 mg/dL. Results: We found a significantly higher mean BMI (kg/m [2] in the HBP group (30.5 ± 6.0 compared to T2DM (28.1 ± 5.9 and concomitant HBP and T2DM groups (29.4 ± 5.2 (ANOVA; P = 0.02.

    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.

    Seiler, Christian A

    2011-08-01

    Patients with an abdominal catastrophe are in urgent need of early, interdisciplinary medical help. The treatment plan should be based on medical priorities and clear leadership. First priority should be given to achieve optimal oxygenation of blood and stabilization of circulation during all treatment-phases. The sicker the patient, the less invasive the (surgical) treatment should to be, which means "damage control only". This short article describes 7 important, pragmatic rules that will help to increase the survival of a patient with an abdominal catastrophe. Preexisting morbidity and risk factors must be included in the overall risk-evaluation for every therapeutic intervention. The challenge in patients with an abdominal catastrophe is to carefully balance the therapeutic stress and the existing resistance of the individual patient. The best way to avoid abdominal disaster, however, is its prevention.

    Lateral abdominal wall muscles in children and adolescents have not been characterised to date. In the present report, we examined the reliability of the ultrasound measurement and thickness of the oblique external muscle (OE), oblique internal muscle (OI) and transverse abdominal muscle (TrA) at rest and during abdominal drawing-in manoeuvre (ADIM) on both sides of the body in healthy adolescents. We also determined possible differences between boys and girls and defined any factors-such as body mass, height and BMI-that may affect the thickness of the abdominal muscles. B-mode ultrasound was used to assess OE, OI and TrA on both sides of the body in the supine position. Ultrasound measurements at rest and during ADIM were reliable in this age group (ICC3,3 > 0.92). OI was always the thickest and TrA the thinnest muscle on both sides of the body. In this group, an identical pattern of the contribution of the individual muscles to the structure of the lateral abdominal wall (OI > OE > TrA) was observed. At rest and during ADIM, no statistically significant side-to-side differences were demonstrated in either gender. The body mass constitutes between 30% and muscles under examination at rest and during ADIM. The structure of lateral abdominal wall in adolescents is similar to that of adults. During ADIM, the abdominal muscles in adolescents react similarly to those in adults. This study provided extensive information regarding the structure of the lateral abdominal wall in healthy adolescents.

    Abdominal symptoms are among the most common reasons for pediatric emergency department visits, and abdominal pain is the most frequently reported symptom. Thorough history taking and physical examination can often reach the correct diagnosis. Knowing the abdominal conditions that are most common in each age group can help radiologists narrow the differential diagnosis. When imaging tests are indicated, ultrasonography is usually the first-line technique, enabling the diagnosis or adding relevant information with the well-known advantages of this technique. Nowadays, plain-film X-ray studies are reserved for cases in which perforation, bowel obstruction, or foreign body ingestion is suspected. It is also important to remember that abdominal pain can also occur secondary to basal pneumonia. CT is reserved for specific indications and in individual cases, for example, in patients with high clinical suspicion of abdominal disease and inconclusive findings at ultrasonography. We review some of the most common conditions in pediatric emergencies, the different imaging tests indicated in each case, and the imaging signs in each condition.

Background: Patients with previous multiple abdominal surgeries are often denied abdominal free flap breast reconstruction because of concerns about flap viability and abdominal wall integrity. We therefore studied their flap and donor site outcomes and compared them to patients with no previous abdominal surgery to find out whether this is a valid contraindication to the use of abdominal tissue. Patients and Methods: Twenty patients with multiple previous abdominal operations who underwent abdominal free flap breast reconstruction by a single surgeon (C.M.M., 2000-2009) were identified and retrospectively compared with a cohort of similar patients without previous abdominal surgery (sequential allocation control group, n = 20). Results: The index and control groups were comparable in age, body mass index, comorbidities, previous chemotherapy, and RT exposure. The index patients had a mean age of 54 years (r, 42-63) and an average body mass index of 27.5 kg/m2 (r, 22-38). The main previous surgeries were Caesarean sections (19), hysterectomies (8), and cholecystectomies (6). They underwent immediate (n = 9) or delayed (n = 11) reconstructions either unilaterally (n = 18) or bilaterally (n = 2) and comprising 9 muscle-sparing free transverse rectus abdominis muscle and 13 deep inferior epigastric perforator flaps. All flaps were successful, and there were no significant differences in flap and donor site outcomes between the 2 groups after an average follow up of 26 months (r, 10-36). Conclusion: Multiple previous abdominal

    Abdominal paracentesis and thoracocentesis are common bedside procedures with diagnostic, therapeutic and palliative roles. We describe a useful and familiar a useful and familiar technique with the use of a multiple lumen catheter commonly used for central venous line insertion for drainage of ascites or moderate to large pleural effusions. The use of a multiple lumen catheter allows easier and more rapid aspiration of fluid with a smaller probability of the side holes being blocked as compared to the standard needle or single catheter methods. This is particularly useful in situations where the dedicated commercial kits for thoracocentesis and abdominal paracentesis are not readily available.

    We report a case of abdominal actinomycosis in a 54 year old woman using an intrauterine device for a period of 8 years. The most important finding was a tuboovarialabscess at the left pelvic side with involvement of the serosa of the jejunum, ileum, sigma, and omentum majus. Intraoperative exploration showed a solid retroperitoneal infiltration between the pelvic side wall and sigma. Another infiltration was found on the left side of the abdominal wall. The diagnosis was confirmed by histopathological examination and the patient was treated by a combination of Aminopenicillin and Metronidazol. After a period of three months we observed a complete regression of the clinical and the MRI findings.

  9. Geological evolution of the marine selenium cycle: Insights from the bulk shale δ82/76Se record and isotope mass balance modeling

    2016-05-01

    Bulk δ82/76Se values of representative marine shales from the Paleoarchean to the present day vary between approximately -3 and + 3 ‰ with only local deviations beyond this range. This muted Se isotope variability in the shale record contrasts with the relatively large fractionations associated with abiotic and microbial Se oxyanion reduction seen in experimental studies. Long-term temporal trends in the bulk shale data do not directly correlate with changes in redox conditions of the global ocean, although a minor but significant shift towards more negative formation-averaged δ82/76Se values appears to track oxygenation of the deep ocean at the end of the Proterozoic. We hypothesize that extensive δ82/76Se variability in the shale data was suppressed due to the early emergence of biological assimilatory uptake and the resulting persistence of low seawater Se concentrations, coupled with small authigenic Se outputs throughout most of geological time. In the modern ocean, Se is an essential micronutrient with a relatively short residence time of about 11,500 yrs. The marine Se cycle is dominated by assimilation into biomass and subsequent recycling in the water column and surface sediments, i.e. processes that result in only minimal isotopic fractionation. We suggest that similar processes dominated back through the geological record to Archean times. Our model shows that paleoceanographic information could in principle be extracted from proxy data on the Se isotopic composition of seawater, once isotopic differences can be readily discerned between individual sedimentary Se pools.

    2008-01-01

    Neurenteric cysts are extremely rare congenital anomalies, often presenting in the first 5 years of life, and are caused by an incomplete separation of the notochord from the foregut during the third week of embryogenesis. They are frequently accompanied with spinal or gastrointestinal abnormalities, but the latter may be absent in adults. Although usually located in the thorax, neurenteric cysts may be found along the entire spine. We present a 24-year-old woman admitted for epigastric pain, nausea, vomiting, low grade fever and leucocytosis. She underwent cystgastrostomy for a loculated cyst of the distal pancreas at the age of 4 years, which recurred when she was at the age of 11 years. Ultrasound and computer tomograghy (CT) scan revealed a 16cm×15cm cystic mass in the body and tail of pancreas, with a 6-7 mm thickened wall. Laboratory data and chest X-ray were normal and spinal radiographs did not show any structural abnormalities. The patient underwent a complete cyst excision, and after an uneventful recovery, remained symptom-free without recurrence during the 5-year follow-up. The cyst was found to contain 1200mL of pale viscous fluid. It was covered by a primitive singlelayered cuboidal epithelium, along with specialized antral glandular parenchyma and hypoplastic primitive gastric mucosa. Focal glandular groups resembling those of the body of the stomach were also seen. In addition, ciliary respiratory epithelium, foci of squamous metaplasia and mucinous glands were present. The wall of the cyst contained a muscular layer, neuroglial tissue with plexogenic nerve fascicles, Paccini corpuscle-like structures, hyperplastic neuroganglionar elements and occasional psammomatous bodies, as well as fibroblast-like areas of surrounding stroma. Cartilagenous tissue was not found in any part of the cyst. Immunohistochemistry confirmed the presence of neurogenic elements marked by S-100, GFAP, NF and NSE. The gastric epithelium showed mostly CK7 and EMA

    2016-01-01

    Iatrogenic parasitic myomas are rare. The condition is defined by the presence of multiple smooth-muscle tumorous nodules in the peritoneal cavity. This may be attributable to seeding of myoma particles during uterine surgery. The clinical course is usually indolent. The disease is often asymptomatic and is usually discovered only incidentally. A 38-year-old woman who had undergone abdominal myomectomy 7 months prior presented with acute abdominal pain and a huge pelvic mass. We performed exploratory laparotomy. A parasitic mass 17 cm in diameter with a twisted omental pedicle was identified. En bloc excision of the mass and omentum was performed, followed by total abdominal hysterectomy. Histopathological examination of multiple sections revealed features compatible with an infarcted leiomyoma. Thus, we present a very rare case of an iatrogenic, rapidly growing parasitic myoma complicated by omental torsion (which caused the acute abdominal pain). We also offer a literature review.

  12. Adult abdominal hernias.

    LENUS (Irish Health Repository)

    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.

    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.

    Lipomas are common benign tumors of mature adipose tissue, enclosed by thin fibrous capsules. They can occur on any part of the body; however, peritoneal lipoma is extremely rare. We encountered a case of a 75-year-old man presenting with intermittent abdominal pain, who had undergone right hemicolectomy due to colon cancer. Abdominal computerized tomography showed a well-defined heterogenous fatty mass measuring 4.5 × 3.5 cm in size, suggesting fat necrosis located in the abdominal wall. Laparotomy showed a very large soft mass of peritoneum. Pathologically, the tumor was diagnosed as lipoma containing fat necrosis located in parietal peritoneum not fixed to any organs, but with small bowel adhesion. Due to its rare etiologic origin and obscure cause of development, we report on a case of lipoma of parietal peritoneum causing abdominal pain.

    Full Text Available CONTEXT: The lithopedion (calcified abdominal pregnancy is a rare phenomenon and there are less than 300 cases reported in the medical literature. CASE REPORT: In this case, a 40 year-old patient had had her only pregnancy 18 years earlier, without medical assistance since then. She came to our hospital with pain and tumoral mass of approximately 20 centimeters in diameter. Complementary examinations (abdominal X-ray, ultrasonography and computerized tomography demonstrated an extra-uterine abdominal 31-week pregnancy with calcification areas. Exploratory laparotomy was performed, with extirpation of a well-conserved fetus with partially calcified ovular membranes.

    Iatrogenic parasitic myomas are rare. The condition is defined by the presence of multiple smooth-muscle tumorous nodules in the peritoneal cavity. This may be attributable to seeding of myoma particles during uterine surgery. The clinical course is usually indolent. The disease is often asymptomatic and is usually discovered only incidentally. A 38-year-old woman who had undergone abdominal myomectomy 7 months prior presented with acute abdominal pain and a huge pelvic mass. We performed exp...

    In recent years, chromatographic columns packed with core-shell particles have been widely used for efficient and fast separations at comparatively low operating pressure. However, the influence of the porous shell properties on the mass transfer kinetics in core-shell packings is still not fully understood. We report on results obtained with a modeling approach to simulate three-dimensional advective-diffusive transport in bulk random packings of monosized core-shell particles, covering a range of reduced mobile phase flow velocities from 0.5 up to 1000. The impact of the effective diffusivity of analyte molecules in the porous shell and the shell thickness on the resulting plate height was investigated. An extension of Giddings' theory of coupled eddy dispersion to account for retention of analyte molecules due to stagnant regions in porous shells with zero mobile phase flow velocity is presented. The plate height equation involving a modified eddy dispersion term excellently describes simulated data obtained for particle-packings with varied shell thickness and shell diffusion coefficient. It is confirmed that the model of trans-particle mass transfer resistance of core-shell particles by Kaczmarski and Guiochon [42] is applicable up to a constant factor. We analyze individual contributions to the plate height from different mass transfer mechanisms in dependence of the shell parameters. The simulations demonstrate that a reduction of plate height in packings of core-shell relative to fully porous particles arises mainly due to reduced trans-particle mass transfer resistance and transchannel eddy dispersion.

    2015-09-02

    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.

    Although most frequently presenting with lower abdominal pain, appendicitis, colitis, and diverticulitis can cause pain throughout the abdomen and can cause peritoneal and retroperitoneal symptoms. Evaluation and management of lower intestinal disease requires a nuanced approach by the emergency physician, sometimes requiring computed tomography, ultrasonography, MRI, layered imaging, shared decision making, serial examination, and/or close follow-up. Once a presumed or confirmed diagnosis is made, appropriate treatment is initiated, and may include surgery, antibiotics, and/or steroids. Appendicitis patients should be admitted. Diverticulitis and inflammatory bowel disease can frequently be managed on an outpatient basis, but may require admission and surgical consultation.

    The purpose of this article is to provide an up to date review on the spectrum of applications of perfusion computed tomography (CT) in the abdomen. New imaging techniques have been developed with the objective of obtaining a structural and functional analysis of different organs. Recently, perfusion CT has aroused the interest of many researchers who are studying the applicability of imaging modalities in the evaluation of abdominal organs and diseases. Per-fusion CT enables fast, non-invasive imaging of the tumor vascular physiology. Moreover, it can act as an in vivo biomarker of tumor-related angiogenesis.

    Endometriosis is the presence of endometrial glands and stroma outside the uterus. Spontaneous abdominal wall endometriosis (AWE) is any ectopic endometrium found superficial to the peritoneum without the presence of any previous scar. Rarely, endometriosis represents a disease of specific interest to the general surgeon, on account of its extrapelvic localisations. We describe a case with spontaneous AWE presenting as a painful mass with cyclic symptoms. A 28-year-old woman presented to the day-surgery division of our department, suffering from a painful mass in the left lower abdominal quadrant. A mobile mass of 5 x 4 cm was identified. The initial diagnosis was lipoma and excision was planned. During the operation two masses were spotted, very close to one another, and were excised within healthy limits. Pathology revealed endometrial glands surrounded by a disintegrating mantle of endometrial stroma and fibrous scar tissue in which there was a scattering of leucocytes. The woman had no scars. She was discharged from hospital after 2 hours. Two years after the excision she is free of disease and no recurrence has been observed. Spontaneous AWE is rare, accounting for 20% of all AWEs. The triad ; mass, pain and cyclic symptomatology helps in the diagnosis, but unfortunately it is not present in all cases. Spontaneous endometriomas are usually diagnosed by pathology and the treatment of choice is surgical excision.

  11. Abdominal-Pelvic Actinomycosis Mimicking Malignant Neoplasm

    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.

    Abdominal wall leiomyoma arising de novo is very rare, hence the reported imaging findings of this disease are also rare. We reported the case of a 33-year-old woman who presented with an abdominal wall mass without antecedent gynecological surgeries. The initial abdominal computed tomography (CT) showed thickening of the left rectus abdominis and the loss of intervening fat between the rectus abdominis and the lateral abdominal muscles. After 8 months, the follow-up contrast-enhanced CT and ultrasonography (US) showed a lentiform-shaped mass with isodensity to the adjacent muscles. The US-guided biopsy was consistent with leiomyoma.

    Leiomyosarcomas are soft tissue tumors that account for approximately 15% of all soft tissue sarcomas. Leiomyosarcomas may be located at almost any part of the abdomen but especially are more common in the retroperitoneum, followed by gastrointestinal tract and genital system. They develop mainly in adult life and are very rare in children. In this article, imaging findings of leiomyosarcomas in various abdominal locations are presented. Radiologic studies are capable of providing useful information on the localization, size, changes in the internal structure of the tumor, its extension and invasion. Leiomyosarcoma should be considered in the differential diagnosis in case of detection of a large, circumscribed, and heterogenous abdominal mass. Histopathologically, diagnosis of malignancy depends particularly on mitotic counts, size, rate of necrosis, and infiltrating margins. (orig.)

  14. Comparative study of ¹³C composition in ethanol and bulk dry wine using isotope ratio monitoring by mass spectrometry and by nuclear magnetic resonance as an indicator of vine water status.

    The potential of wine (13)C isotope composition (δ(13)C) is presented to assess vine water status during grape ripening. Measurements of δ(13)C have been performed on a set of 32 authentic wines and their ethanol recovered after distillation. The data, obtained by isotope ratio monitoring by mass spectrometry coupled to an elemental analyser (irm-EA/MS), show a high correlation between δ(13)C of the bulk wine and its ethanol, indicating that the distillation step is not necessary when the wine has not been submitted to any oenological treatment. Therefore, the ethanol/wine δ(13)C correlation can be used as an indicator of possible enrichment of the grape must or the wine with exogenous organic compounds. Wine ethanol δ(13)C is correlated to predawn leaf water potential (R(2) = 0.69), indicating that this parameter can be used as an indicator of vine water status. Position-specific (13)C analysis (PSIA) of ethanol extracted from wine, performed by isotope ratio monitoring by nuclear magnetic resonance (irm-(13)C NMR), confirmed the non-homogenous repartition of (13)C on ethanol skeleton. It is the δ(13)C of the methylene group of ethanol, compared to the methyl moiety, which is the most correlated to predawn leaf water potential, indicating that a phase of photorespiration of the vine during water stress period is most probably occurring due to stomata closure. However, position-specific (13)C analysis by irm-(13)C NMR does not offer a greater precision in the assessment of vine water status compared to direct measurement of δ(13)C on bulk wine by irm-EA/MS.

    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.)

    Abdominal actinomycosis is a severe and progressive peritoneal infection, due to an anerobic gram-positive bacterium, Actinomyces israelii. The presence of a long-standing intrauterine device (IUD) is a well-known risk factor in young women. We report two cases of pelviperitoneal actinomycosis appearing in two young women with acute low abdominal pain. Abdominal CT demonstrated multiple solid or encapsulated peritoneal masses with marked contrast enhancement and infiltration of the adjacent mesenteric fat. Laparoscopy confirmed the presence of intraperitoneal abscesses which contained Actinomyces israelii. High doses of amoxicillin and clavulanic acid (Augmentine) were given and following CT scan after 2 and 6 weeks showed a slow, but complete, resolution of the lesions. Although the radiologic presentation of actinomycosis is nonspecific, the diagnosis should be raised in the presence of pseudotumoral mesenteric infiltration, particularly in young women with an IUD. Abdominal CT is a useful method for diagnosis and for follow-up.

    2015-06-01

    Although traditionally regarded as a specific pediatric disease, abdominal migraine may also be observed in adults. Unfortunately, however, this condition is frequently overlooked in the differential diagnosis of abdominal pain in the emergency department (ED). A 30-year-old woman presented to our ED complaining of abdominal pain and vomiting, lasting for 12 hours. The pain was periumbilical, continuous, and not associated with fever or diarrhea. The physical examination and the results of conventional blood tests were normal. The patient was treated with intravenous ketoprofen, metoclopramide, and ranitidine, obtaining a prompt relief of symptoms. She had a history of similar episodes in the last 15 years, with several ED visits, blood test examinations, ultrasonography of the abdomen, and upper gastrointestinal endoscopies. Celiac disease, porphyry, sickle cell disease, and inflammatory bowel disease were all excluded. In July 2012, she became pregnant, and she delivered a healthy baby on April 2013. Until November 2014, she has remained asymptomatic. Based on the clinical characteristics of the abdominal pain episodes, the exclusion of any alternative diagnosis, and the relief of symptoms during and after pregnancy, a final diagnosis of abdominal migraine could be established. A skilled emergency physician should always consider abdominal migraine in the differential diagnosis of patients admitted to the ED with abdominal pain, especially when the attacks are recurrent and no alternative diagnosis can be clearly established.

    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.

Methods: An observational explorative study was conducted. 25 preterm and 10 full term infants were evaluated at 0-1 month of corrected and postnatal age, respectively. The total body fat mass was assessed by means of an air displacement plethysmography system (Pea Pod COSMED, USA and the intra-abdominal adipose tissue by means of magnetic resonance imaging (software program SliceOMatic, Version 4.3,Tomovision, Canada. Results: Total body fat mass (g of preterm and term infants was 633 (±183 and 538 (±203 respectively while intra-abdominal fat mass (g was 14.2 (±4.9 and 19.9 (±11.4. Conclusions: Preterm infants, although exhibiting a total body fat mass higher than full term infants, do not show an increased intra-abdominal adipose tissue.

    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.

    2013-07-01

    Full Text Available The contribution of abdominal aortic aneurysm (AAA disease to human morbidity and mortality has increased in the aging, industrialized world. In response, extraordinary efforts have been launched to determine the molecular and pathophysiological characteristics of the diseased aorta. This work aims to develop novel diagnostic and therapeutic strategies to limit AAA expansion and, ultimately, rupture. Contributions from multiple research groups have uncovered a complex transcriptional and post-transcriptional regulatory milieu, which is believed to be essential for maintaining aortic vascular homeostasis. Recently, novel small noncoding RNAs, called microRNAs, have been identified as important transcriptional and post-transcriptional inhibitors of gene expression. MicroRNAs are thought to “fine tune” the translational output of their target messenger RNAs (mRNAs by promoting mRNA degradation or inhibiting translation. With the discovery that microRNAs act as powerful regulators in the context of a wide variety of diseases, it is only logical that microRNAs be thoroughly explored as potential therapeutic entities. This current review summarizes interesting findings regarding the intriguing roles and benefits of microRNA expression modulation during AAA initiation and propagation. These studies utilize disease-relevant murine models, as well as human tissue from patients undergoing surgical aortic aneurysm repair. Furthermore, we critically examine future therapeutic strategies with regard to their clinical and translational feasibility.

Despite having a number of recognised risk factors for an AAA, her general practitioner at the time did not follow the guidance set out by the private medical professional, that is, to refer the patient to a vascular specialist to be entered into a surveillance programme and surgically evaluated. The patient became symptomatic with her AAA, was admitted to hospital and found to have a tender, symptomatic, 6 cm leaking AAA. She consented for an emergency open AAA repair within a few hours of being admitted to hospital, despite the 50% perioperative mortality risk. The patient spent 4 days in intensive care where she recovered well. She was discharged after a 12 day hospital stay but unfortunately passed away shortly after her discharge from a previously undiagnosed gastric cancer.

    We investigate and review concepts of multi - seeded REBCO bulk superconductors in mobile application. ATZ's compact HTS bulk magnets can trap routinely 1 T@77 K. Except of magnetization, flux creep and hysteresis, industrial - like properties as compactness, power density, and robustness are of major device interest if mobility and light-weight construction is in focus. For mobile application in levitated trains or demonstrator magnets we examine the performance of on-board cryogenics either by LN2 or cryo-cooler application. The mechanical, electric and thermodynamical requirements of compact vacuum cryostats for Maglev train operation were studied systematically. More than 30 units are manufactured and tested. The attractive load to weight ratio is more than 10 and favours group module device constructions up to 5 t load on permanent magnet (PM) track. A transportable and compact YBCO bulk magnet cooled with in-situ 4 Watt Stirling cryo-cooler for 50 - 80 K operation is investigated. Low cooling power and effective HTS cold mass drives the system construction to a minimum - thermal loss and light-weight design.

    We report the case of a 15-year-old boy suffering from progressive dyspnea on exertion and painful abdominal protrusion. Final diagnosis of intra-abdominal tuberculosis (TB), including lymphadenopathy and abdominal abscess formation, was made following elective laparotomy. This type of disease is a rare manifestation of extrapulmonary tuberculosis. The imaging findings in unenhanced and contrast-enhanced MRI and laparoscopic images are presented. Differential diagnosis of abdominal abscess formation and other fungal or bacteriological infections, as well as the imaging findings of this type of lesion, are discussed. This case demonstrates that atypical manifestation of TB may remain unrecognized; thus, awareness of this kind of manifestation of tuberculosis may prevent patients from being subjected to inappropriate therapies.

    Institute of Scientific and Technical Information of China (English)

    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.

  15. Common abdominal emergencies in children.

    Science.gov (United States)

    D'Agostino, James

    2002-02-01

    Because young children often present to EDs with abdominal complaints, emergency physicians must have a high index of suspicion for the common abdominal emergencies that have serious sequelae. At the same time, they must realize that less serious causes of abdominal symptoms (e.g., constipation or gastroenteritis) are also seen. A gentle yet thorough and complete history and physical examination are the most important diagnostic tools for the emergency physician. Repeated examinations and observation are useful tools. Physicians should listen carefully to parents and their children, respect their concerns, and honor their complaints. Ancillary tests are inconsistent in their value in assessing these complaints. Abdominal radiographs can be normal in children with intussusception and even malrotation and early volvulus. Unlike the classic symptoms seen in adults, young children can display only lethargy or poor feeding in cases of appendicitis or can appear happy and playful between paroxysmal bouts of intussusception. The emergency physician therefore, must maintain a high index of suspicion for serious pathology in pediatric patients with abdominal complaints. Eventually, all significant abdominal emergencies reveal their true nature, and if one can be patient with the child and repeat the examinations when the child is quiet, one will be rewarded with the correct diagnosis.

    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

  1. Electromyographic investigation of abdominal exercises and the effects of fatigue.

    Science.gov (United States)

    Robinson, Mark; Lees, Adrian; Barton, Gabor

    Abdominal exercises are widely used to develop the anterior muscles of the trunk. These exercises can be undertaken without the aid of equipment, but increasingly manufacturers are developing equipment which purportedly enhances the training effect for abdominal muscles. As there are many different products and exercises used for abdominal muscle development, it is likely that some are more effective than others. This study aimed to investigate the effectiveness of five commonly performed abdominal exercises. A second aim was to investigate the effects of fatigue on these exercises. Five different types of abdominal exercise [standard crunch (sit-up) with bent knees, gym ball crunch, crunch with 5 kg weight held behind the head, legs raised crunch and a commercially manufactured roller crunch] were examined using integrated surface electromyography (IEMG). The lower rectus abdominis (LRA), upper rectus abdominis (URA) and obliquus externus abdominis (EO) of 15 healthy male participants [age (mean +/- SD) 22.2 +/- 6.8 years; height 1.77 +/- 0.06 m; mass 79.3 +/- 10.7 kg] were monitored using a four-channel special purpose EMG data logger. Three trials of each exercise were performed in random order and normalized to enable comparisons between muscles and exercises. At a later date, ten participants were then re-tested when fresh and after a 30 min whole-body fatigue protocol that specifically targeted the abdominal muscles. Two exercises were evaluated, the abdominal roller crunch and legs raised crunch, which were judged to be the least and most effective, respectively, of the five exercises previously used. The normalized IEMG showed significant (p crunch = 86.0 +/- 7.5%; legs raised crunch = 79.9 +/- 5.1%; 5 kg weight crunch = 65.1 +/- 13.4%; standard crunch = 56.2 +/- 3.2%; and roller crunch = 45.0 +/- 11.4%). Post-fatigue, the normalized mean IEMG for both exercises increased significantly (p 0.05). It was concluded that exercises can be constructed to provide

    We report two cases of pelviperitoneal actinomycosis appearing in two young women with acute low abdominal pain. Abdominal CT demonstrated multiple solid or encapsulated peritoneal masses with marked contrast enhancement and infiltration of the adjacent mesenteric fat. Laparoscopy confirmed the presence of intraperitoneal abscesses which contained Actinomyces israelii. High doses of amoxicillin and clavulanic acid (Augmentine) were given and following CT scan after 2 and 6 weeks showed a slow, but complete, resolution of the lesions. Although the radiologic presentation of actinomycosis is nonspecific, the diagnosis should be raised in the presence of pseudotumoral mesenteric infiltration, particularly in young women with an IUD. Abdominal CT is a useful method for diagnosis and for follow-up. (orig./MG)

    The incidence of abdominal pregnancy is very rare, long-retained abdominal pregnancy undergoing fetal death and evolving to a lithopaedion is even more scarce. The authors report the case of a 60-year-old woman who discovered an abdominal mass 31 years ago that was recently identified intraoperatively as lithopaedion. Although imaging had revealed a low-level echogenic mass in the cavity, nobody had considered the possibility of a lithopaedion before the operation. The authors strongly suggest identifying the small skeletal frame through imaging that will be a very important preoperative sign that will lead to a diagnosis, otherwise neglected in the past years.

    importance of Body Mass Index (BMI and waist circumference for the determination of hypertension in adults. METHODS: Cross sectional analysis of a sample of employees (N=1,584, aged 18 to 64 years, from a private general hospital in the city of São Paulo, Brazil. Data collection included the application of a structured questionnaire and blood pressure, weight, high, and waist circumference measurements. Hypertension was defined as blood pressure levels > 140/90 mmHg or reported use of anti-hypertensive medication. The relative importance of BMI and waist circumference was evaluated by calculating the attributable fraction of hypertension corresponding to each anthropometric indicator, employing both the usual cut-off points as well as cut-off points based on the observed distribution of the indicator in the population. In addition, an indicator combining simultaneously BMI and abdominal circumference values was also developed. RESULTS: Prevalence of hypertension was 18.9% (26.9% in men and 12.5% in women. In men, the fraction of hypertension attributable to BMI exceeded the fraction attributable to waist circumference based on the usual cut-off points for the indicators (56% vs. 48%, respectively and also considering the quartiles of the observed distribution for these indicators (73% vs. 69%, respectively. In women, the fraction of hypertension attributable to waist circumference was slightly higher than the fraction attributable to BMI based on the usual cut off points for both indicators (44% vs. 41%, but the reverse was true when quartiles of the observed distribution were used (41% vs. 57%, respectively. In women only, the fraction of hypertension attributable to the indicator combining BMI and waist circumference (64% was higher that observed using each indicator alone. CONCLUSIONS: Both BMI and abdominal circumference were positively and independently associated with the occurrence of arterial hypertension, the influence of BMI being higher among men.

    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.

    Measurement and feedback control of nutrient solutions in plant root zones is critical to the development of healthy plants in both terrestrial and reduced-gravity environments. In addition to the water content, the amount of fertilizer in the nutrient solution is important to plant health. This typically requires a separate set of sensors to accomplish. A combination bulk moisture and salinity sensor has been designed, built, and tested with different nutrient solutions in several substrates. The substrates include glass beads, a clay-like substrate, and a nutrient-enriched substrate with the presence of plant roots. By measuring two key parameters, the sensor is able to monitor both the volumetric water content and salinity of the nutrient solution in bulk media. Many commercially available moisture sensors are point sensors, making localized measurements over a small volume at the point of insertion. Consequently, they are more prone to suffer from interferences with air bubbles, contact area of media, and root growth. This makes it difficult to get an accurate representation of true moisture content and distribution in the bulk media. Additionally, a network of point sensors is required, increasing the cabling, data acquisition, and calibration requirements. measure the dielectric properties of a material in the annular space of the vessel. Because the pore water in the media often has high salinity, a method to measure the media moisture content and salinity simultaneously was devised. Characterization of the frequency response for capacitance and conductance across the electrodes was completed for 2-mm glass bead media, 1- to 2-mm Turface (a clay like media), and 1- to 2-mm fertilized Turface with the presence of root mass. These measurements were then used to find empirical relationships among capacitance (C), the dissipation factor (D), the volumetric water content, and the pore water salinity.

    Abdominal injuries are rare in sports, but when they do occur it is important that the physician recognize the warning signs of potentially life-threatening injury to the liver, spleen, or hollow abdominal viscera. Though the sports medicine physician may not always provide definitive treatment of many of these conditions, he or she should be familiar with the preferred diagnostic modalities and latest treatment options. This information is not only essential to appropriately participate in treatment decisions, but is also important in order to make return-to-play determinations.

    The authors report the case of a 93-year old woman referred to the emergency department and presenting with an intestinal obstruction. Abdominal CT reveals a biliary ileus caused by the migration and the impaction of a 3 cm gallstone in the small bowel. Surgical treatment by enterolithotomy was successful. In over 90% of cases, gallstone ileus is a complication of cholelithiasis and accounts for 25% of intestinal obstruction in patients over 65 years. To reduce morbidity and mortality, early diagnosis and prompt treatment are essential. Abdominal CT-scan is the gold standard technique.

    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.

  12. Gravitational potential wells and the cosmic bulk flow

    Kumar, Abhinav; Feldman, Hume A; Watkins, Richard

    2015-01-01

    The bulk flow is a volume average of the peculiar velocities and a useful probe of the mass distribution on large scales. The gravitational instability model views the bulk flow as a potential flow that obeys a Maxwellian Distribution. We use two N-body simulations, the LasDamas Carmen and the Horizon Run, to calculate the bulk flows of various sized volumes in the simulation boxes. Once we have the bulk flow velocities as a function of scale, we investigate the mass and gravitational potential distribution around the volume. We found that matter densities can be asymmetrical and difficult to detect in real surveys, however, the gravitational potential and its gradient may provide better tools to investigate the underlying matter distribution. This study shows that bulk flows are indeed potential flows and thus provides information on the flow sources. We also show that bulk flow magnitudes follow a Maxwellian distribution on scales $>10\\ h^{-1}$Mpc.

  14. Radiative Bulk Viscosity

    2001-01-01

    Viscous resistance to changes in the volume of a gas arises when different degrees of freedom have different relaxation times. Collisions tend to oppose the resulting departures from equilibrium and, in so doing, generate entropy. Even for a classical gas of hard spheres, when the mean free paths or mean flight times of constituent particles are long, we find a nonvanishing bulk viscosity. Here we apply a method recently used to uncover this result for a classical rarefied gas to radiative transfer theory and derive an expression for the radiative stress tensor for a gray medium with absorption and Thomson scattering. We determine the transport coefficients through the calculation of the comoving entropy generation. When scattering dominates absorption, the bulk viscosity becomes much larger than either the shear viscosity or the thermal conductivity.

    Objective: To improve the prognosis of patients with abdominal trauma. Methods: Between January 1993 and December 2005, 415 patients were enrolled in this research. The patients consisted of 347 males and 68 females with mean age of 36 years ranging from 3-82 years. All abdominal traumas consisted of closed traumas 360 cases, 86.7% and open traumas 55 cases, 13.3%. Results: Atotal of 407 cases 98.1% were fully recovered from trauma and the other 8 cases 1.9% died of multiple injuries. The mean injury severity score ISS of all patients was 22 while the mean ISS of the patients who died in hospital was 42. Postoperative complications were seen in 9 patients such as infection of incisional wounds 6 cases, pancreatic fistula 2 cases and intestinal fistula 1 case. All these postoperative complications were cured by the conservative treatment. Conclusion: Careful case history inquisition and physical examination are the basic methods to diagnose abdomi- nal trauma. Focused abdominal ultrasonography is always the initial imaging examination because it is non-invasive and can be performed repeatedly with high accuracy. The doctors should consider the severity of local injuries and the general status of patients during the assessment of abdominal trauma. The principle of treatment is to save lives at first, then to cure the injuries. Unnecessary laparotomy should be avoided to reduce additional surgical trauma.

    Objective: To determine the effective dose in abdominal computed tomography imaging and to study the influence of patients' characteristics on the received dose. Materials and Methods: Dose values measurements were performed with an ionization chamber on phantoms to check the agreement between dose values and those presented by the computed tomography apparatus, besides their compliance with the recommended reference dose levels. Later, values of dose received by physically able patients submitted to abdominal computed tomography (n = 100) were measured and correlated with their anthropometric characteristics. Finally, the dose to organs was simulated with the Monte Carlo method using the CT-Expo V 1.5 software, and the effect of automatic exposure control on such examinations. Results: The main characteristics directly influencing the dose include the patients' body mass, abdominal perimeter and body mass index, whose correlation is linear and positive. Conclusion: The radiation dose received from abdominal CT scans depends on some patient's characteristics, and it is important to adjust the acquisition parameters to their dimensions (author)

  3. A Diphoton Resonance from Bulk RS

    CERN Document Server

    Csaki, Csaba

    2016-01-01

    Recent LHC data hints at a 750 GeV mass resonance that decays into two photons. A significant feature of this resonance is that its decays to Higges and to any other Standard Model particles are so far too low to be detected. Such a state has a compelling explanation in terms of a scalar or a pseudoscalar that is strongly coupled to vector states charged under the Standard Model gauge groups. We argue that if the state is a scalar, some form of sequestering is likely to be necessary to naturally explain the suppressed scalar-Higgs interactions. Such a scenario is readily accommodated in bulk RS with a scalar localized in the bulk away from the Higgs. Turning this around, we argue that a good way to find the elusive bulk RS model might be the search for a resonance with prominent couplings to gauge bosons.

    Full Text Available Endometriosis is a frequent benign disorder. Malignancy arising in extraovarian endometriosis is a rare event. A 49-year-old woman is presented with a large painful abdominal wall mass. She underwent a myomectomy, 20 years before, for uterus leiomyoma. Computed tomography suggested that this was a desmoid tumor and she underwent surgery. Histological examination showed a clear cell adenocarcinoma associated with endometriosis foci. Pelvic ultrasound, computed tomography, and endometrial curettage did not show any malignancy or endometriosis in the uterus and ovaries. Adjuvant chemotherapy was recommended, but the patient was lost to follow up. Six months later, she returned with a recurrence of the abdominal wall mass. She was given chemotherapy and then she was reoperated.

    Proteus syndrome is an extremely rare congenital disorder that produces multifocal overgrowth of tissue. This report presents a surgical case of a large lipoma in the abdominal wall of a patient with Proteus syndrome. She was diagnosed with Proteus syndrome based on certain diagnostic criteria. The neoplasm increased in size gradually, producing hemihypertrophy of her left lower extremity and trunk, and spread to her retroperitoneum and her left abdominal wall. She experienced gradually progressive constipation, nausea, vomiting, and abdominal pain. Computed tomography (CT) of the abdomen demonstrated a large mass in the subcutaneous adipose tissue of the left lower abdominal wall which measured 12 cm x 8 cm x 6 cm in diameter and encased the left colon. This mass in the abdominal wall was excised. The weight of the excised mass was 1550 g. The histopathological diagnosis of this mass was lipoma. After surgery, the encasement of the left colon was improved, and the patient was able to move her bowels twice per day. The excision of the large lipoma in the abdominal wall contributed to the improved bowel passage in this patient with Proteus syndrome.

    Full Text Available Purpose:The objective of this study was to determine the diagnostic value of intra-abdominal pressure measurement in blunt abdominal trauma patients. Method: A prospective study was performed in 49 patients with blunt trauma in our university hospital for 1 years. Patients were randomly into two groups as intra-abdominal trauma (n=28 and extraabdominal trauma (n=21 groups. Intra-abdominal pressures was measured an classified as normal (10 cm H2O or less, elevated (more than 10 cm H2O determined indirectly. Results: No significant differences were found between abdominal trauma and extra-abdominal trauma groups from the point of intra-abdominal pressure (IAP. One the other hand, in abdominal trauma group; significant differences were observed between operated patients. Intra-abdominal bleeding was found in 10 patients and all of them elevated IAP values (exceeding 16 cm H2O. For determining the intra-abdominal injury, IAP had a sensitivity of 93%, specificity 38% in patients. Conclusion: IAP exceeding 16 cm H2O with blunt abdominal trauma patients abdominal trauma can be detected. It is thought that IAP, indirect monitoring of abdominal trauma patients is a reproducible, scientific guide and simple method.To determine the efficacy of the measurement of intra-abdominal pressure in blunt abdominal trauma patients, further studies should be done.

    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.

    We report two cases of isolated abdominal wall actinomycosis and review 18 previously reported cases to further characterize the clinical findings and the therapeutic management of this syndrome. This diagnosis would be advocated in patients with a palpable abdominal mass of subacute appearance with a previous history of digestive medical illness, diabetes, abdominal surgery, or prolonged IUD use. In contrast with other actinomycosis locations, remarkable data were a more elevated mean age of patients; a female predominance; a prevalent location of mass in abdominal lower left quadrant; and a shorter duration of symptomatology before to diagnosis. The CT is the first choice for imaging study and percutaneous needle aspiration would be recommended for definite diagnosis. The long-term antibiotic therapy, with or without percutaneous drainage, is the first treatment choice because is very effective and made unnecessary a more invasive surgical management. The prognosis is excellent with adequated treatment.

    Nanocrystalline and nanostructured materials offer unique microstructure-dependent properties that are superior to coarse-grained materials. These materials have been shown to have very high hardness, strength, and wear resistance. However, most current methods of producing nanostructured materials in weapons-relevant materials create powdered metal that must be consolidated into bulk form to be useful. Conventional consolidation methods are not appropriate due to the need to maintain the nanocrystalline structure. This research investigated new ways of creating nanocrystalline material, new methods of consolidating nanocrystalline material, and an analysis of these different methods of creation and consolidation to evaluate their applicability to mesoscale weapons applications where part features are often under 100 {micro}m wide and the material's microstructure must be very small to give homogeneous properties across the feature.

    Full Text Available Background: Obesity is a worldwide health problem which is associated with a lot of complications. One of these comorbidities is the metabolic syndrome that is in correlation with abdominal fat thickness and waist circumference. Various methods were used to reduce abdominal fat thickness such as liposuction. A noninvasive method is the topical agent. In this study, we investigated the effectiveness of Arnebia euchroma (AE ointment on the abdominal fat thickness. Materials and Methods: This study was a double-blind clinical trial which was done at the endocrinology clinic in Khorshid Hospital, Isfahan, Iran, in 2014. After explaining the procedure and obtaining informed consent, the candidates were randomly divided into the case and control groups. The participants of the case and control groups applied AE ointment or placebo for 6 weeks on their abdominal area. Body mass index, waist and buttock circumference, and abdominal fat thickness were measured in both case and control groups at their first visit and then at the next 2, 4, and 6 weeks. We used t-test for comparing parametric variables between groups, paired t-test for changes from baseline to final, and repeated measure ANOVA for changes at different steps. Results: Sixty female candidates participated in this study (thirty in each group. Ten patients left the study and fifty participants finished the trial. At the end of the study, participants had a significant weight loss (2.96 ± 1.6 kg, P < 0.001 that was slightly more in the case group (3.15 ± 1.5 kg vs. 2.75 ± 1.7, P = 0.375. Abdominal circumference also decreased significantly in the participants (11.3 ± 6.7 cm, P < 0.001, but the changes were more significant in the case group (13.9 vs. 6.5 cm, P = 0.004. Similarly, abdominal fat thickness decreased significantly in the participants (2.3 ± 1.1 cm, P < 0.001, although changes were not significantly different between two groups (2.53 vs. 2.04 cm, P = 0.139.

    A 49 year-old patient with the complaint of a mass located in the caesarean scar was admitted. There was a fixed mass 30í30 mm in diameter with regular contour located at the right corner of the pfannenstiel incision. Computed tomography revealed a (40í50í50) mm solid mass lesion with margins that cannot be distinguished from the uterus, bladder and small intestines and a heterogeneous mass lesion (50í45í55) mm in diameter, located in the right side of the anterior abdominal wall. Cytoreductive surgery including total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed. Final pathology was clear cell carcinoma. Clear cell carcinoma arising from an extraovarian endometriotic focus was diagnosed and the patient received 6 cycles paclitaxel-carboplatin chemotherapy as adjuvant treatment. The patient who was lost to follow-up applied to our clinic 2 years after surgery with a recurrent mass in the left inguinal region. After 3 cycles of chemotherapy, the patient's tumoral mass in the left inguinal region was excised. The result of the pathology was carcinoma metastasis. It is decided that the following treatment of the patient should be palliative radiation therapy. The patient who underwent palliative radiation therapy died of disease after 4 months of the second operation.

    Women with pre-gravid obesity are at risk for pregnancy complications. While the macrophage response of obese pregnant women categorized by body mass index (BMI) has been documented, the relationship between the peripheral CD4(+) T cell cytokine profile and body fat compartments during pregnancy is unknown. In this study, third trimester peripheral CD4(+) T cell cytokine profiles were measured in healthy pregnant women [n=35; pre-pregnancy BMI: 18.5-40]. CD4(+) T cells were isolated from peripheral blood mononuclear cells and stimulated to examine their capacity to generate cytokines. Between 1 and 3weeks postpartum, total body fat was determined by dual-energy X-ray absorptiometry and abdominal subcutaneous and visceral fat masses were determined by magnetic resonance imaging. Pearson's correlation was performed to assess relationships between cytokines and fat mass. Results showed that greater abdominal visceral fat mass was associated with a decrease in stimulated CD4(+) T cell cytokine expression. IFN-gamma, TNF-alpha, IL-12p70, IL-10 and IL-17A were inversely related to visceral fat mass. Chemokines CCL3 and IL-8 and growth factors G-CSF and FLT-3L were also inversely correlated. Additionally, total body fat mass was inversely correlated with FGF-2 while abdominal subcutaneous fat mass and BMI were unrelated to any CD4(+) T cell cytokine. In conclusion, lower responsiveness of CD4(+) T cell cytokines associated with abdominal visceral fat mass is a novel finding late in gestation.

    Full Text Available The incidence of intraperitoneal adhesion after abdominal surgery was studied. Peritoneoscopy was performed in 933 patients with liver diseases over the 6 year 5 month period from March 1974 to July 1980. Of the patients, 352 (37.7% had undergone an abdominal operation, and intraperitoneal adhesion was detected in 205 (58.2% of these patients. The liver was not observable in 5 out of 61 patients with adhesions after upper abdominal operations. Whereas, the liver was clearly observable in patients with lower abdominal operations in spite of adhesions. Out of the 581 patients without any abdominal operations, 30 patients (5.2% had adhesions in the abdominal cavity, and 6 of them had extensive adhesions that partially obscured the observation of liver surface. In all patients, peritoneoscopy was performed without complications by avoiding the surgical scar for puncture sites and ensuring a free air lumen before trocar puncture.

    Full Text Available The management of the abdominal compartiment syndrome is still a controversial point nowadays. Its early diagnosis and treatment constitute a challenge for surgeons and physicians at the intensive care unit who have to face these cases . The physiopathologic changes that can occur can lead to the patients death, constituting pulmonary thromboembolism and multiorgan failure the principal causes of death. This paper presents the principal clinical parameters and technical procedures for its diagnosis and treatment with the aim of diminishing its morbi-mortality raits in our hospitals

    2016-08-01

    With an aging population, emergency department clinicians can expect an increase in geriatric patients presenting with abdominal pain. Compared with younger patients, this patient population is less likely to present with classic symptoms, physical examination findings, and laboratory values of abdominal disease. However, the morbidity and mortality associated with elderly patients presenting with abdominal pathologic conditions are significant. For this reason, the clinician must be familiar with some subtle and not so subtle differences when caring for the geriatric patient with abdominal pain to ensure timely diagnosis and appropriate treatment.

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.

    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.

    The role of magnetic resonance angiography (MRA) in the evaluation of vascular involvement was studied in 55 patients with abdominal neoplasms. A 2-D time-of-flight (TOF) technique was used in all patients. All patients underwent CT and MR examinations before MRA. Also, MR angiograms were compared with digital subtraction angiography in 22 cases, with Doppler US in 13 cases, and with surgical findings in 20 cases. In all patients with liver neoplasms (n=29) MRA demonstrated the absence of flow in the infiltrated segments. Pericapsular neovascularization was observed in 12 patients. Portal vein involvement was correctly detected in 27 patients. In all cases MRA demonstrated in relationship between the tumor and venous structures. Portosystemic shunts were visualized in 20 of 21 patients with portal hypertension. Vena cava thrombosis (3 cases), compression (5 cases), and displacement (2 cases) were correctly demonstrated. In renal (n=6) and adrenal gland (n=3) tumors renal vein compression was correctly detected in 2 cases, displacement in 1 case, and thrombosis in 3 cases, with only 1 false-positive finding. In 7 patients with pancreatic tumors MRA demonstrated splenic vein thrombosis in 2 cases and compression in 2 cases, with one false-positive finding. Our results indicate that MRA provides precise information regarding venous vascular involvement in abdominal neoplasms, but preoperative arterial mapping is still problematic. (orig.)

  19. Bulk Higgs with a heavy diphoton signal

    2017-02-01

    We consider scenarios of warped extra dimensions with all matter fields in the bulk and in which both the hierarchy and the flavor puzzles of the Standard Model are addressed. Inspired by the puzzling excess of diphoton events at 750 GeV reported in the early LHC Run II data (since then understood as a statistical excess), we consider here the general question as to whether the simplest extra-dimensional extension of the Standard Model Higgs sector, i.e., a five-dimensional bulk Higgs doublet, can lead to an intermediate mass resonance (between 500 GeV and 1.5 TeV) of which the first signature would be the presence of diphoton events. This surprising phenomenology can happen if the resonance is the lightest C P -odd state coming from the Higgs sector. No new matter content is required, the only new ingredient being the presence of (positive) brane localized kinetic terms associated to the five-dimensional bulk Higgs (which reduce the mass of the C P -odd states). Production and decay of this resonance can naturally give rise to observable diphoton signals, keeping dijet production under control, with very low ZZ and WW signals and with a highly reduced top pair production in an important region of parameter space. We use the 750 GeV excess as an example case scenario.

    Because of the radiation dose in computed tomography (CT) is relatively high, it is important to have an estimate of the dose to which the patient is submitted, considering parameters and correction factors, so that the value is closer to the real. The objective of this study is to relate the estimated dose in patients undergoing abdominal CT with BMI (Body Mass Index) groups, considering the specific size of the anatomical region. The work developed in a hospital in Porto Alegre, Brazil, using 16 Siemens Somatom Emotion equipment. We selected 30 adult that underwent to CT of the abdomen in January 2014. Of these, 13 using dose reduction mechanism (Care Dose), (Sample 1) and the rest without this mechanism (Sample 2). Registered weight, height, CTDI{sub vol} (Computed Tomography Dose Index) and anteroposterior and lateral diameter at the umbilicus. BMI and the correction factor for the dose estimates were calculated, according to the specific size of the abdomen. It was determined the percentage change between the CTDI{sub vol} values provided by CT and the value of CTDI{sub vol} after application of the correction factor, plus the average percentage change for each BMI group. The mean percentage change was between 54% and 19% for sample 1 and between 35% and 10% for sample 2, the lowest to highest BMI group. There was a reduction in the medium average percent with the increasing of the BMI groups in both samples. A larger sample of individuals for verification of results is required.

    Solid pseudo-papillary tumor (SPT) of the pancreas is a relatively benign tumor that is more frequently reported in females. Most patients usually present with abdominal pain or mass. We experienced the girl who identified SPT with the injury. We diagnosed SPT in a previously healthy 14-year-old Asian girl after abdominal injury. She experienced upper abdominal pain and vomiting after being hit by a basketball. Blood examination revealed a high serum amylase level. Abdominal radiography indicated abnormal bowel gases. Contrast-enhanced computed tomography revealed a smooth, peripheral and unilocular mass approximately 55 mm in diameter in the pancreatic tail. Based on these observations, acute pancreatitis complicated by a pancreatic mass was initially diagnosed. Therapy for acute pancreatitis was instituted, while we simultaneously investigated the mass. Levels of tumor markers were not profoundly elevated in serum. Dynamic contrast-enhanced magnetic resonance imaging (MRI) revealed moderate and gradual increase in contrast-enhanced imaging, consistent with findings of SPT of the pancreas. We thus elected surgical resection for her. Pathological examination of the surgical specimen confirmed our diagnosis of SPT. SPT of the pancreas should be considered as a differential diagnosis of acute abdomen disorders, especially in instances after minor abdominal injuries in young women, and diagnoses must be confirmed with MRIs.

    Proteus syndrome is an extremely rare congenital disorder that produces multifocal overgrowth tissue. This report presents a surgical case of a large lipoma in the abdominal wall of a patient with Proteus syndrome. She was diagnosed with Proteus syndrome based on certain diagnostic criteria. The neoplasm increased in size gradually, producing hemihypertrophy of her left lower extremity and trunk, and spread to her retroperitoneum and her left abdominal wall. She experienced gradually progressive constipation,nausea, vomiting, and abdominal pain. Computed tomography (CT) of the abdomen demonstrated large mass in the subcutaneous adipose tissue of the cm x 6 cm in diameter and encased the left colon. This mass in the abdominal wall was excised. The weight of the excised mass was 1550 g. The histopathological diagnosis of this mass was lipoma. After surgery, the encasement of the left colon was improved, and the patient was able to move her bowels twice per day. The excision of the large lipoma in the abdominal wall contributed to the improved bowel passage in this patient with Proteus syndrome.

    2013-01-01

    Full Text Available Abstract Background Abdominal wall hematomas are an uncommon cause of acute abdominal pain and are often misdiagnosed. They are more common in elderly individuals, particularly in those under anticoagulant therapy. Most abdominal wall hematomas occur in the rectus sheath, and hematomas within the oblique muscle are very rare and are poorly described in the literature. Here we report the case of an oblique muscle hematoma in a middle-aged patient who was not under anticoagulant therapy. Case presentation A 42-year-old Japanese man presented with a painful, enlarging, lateral abdominal wall mass, which appeared after playing baseball. Abdominal computed tomography and ultrasonography showed a large soft tissue mass located in the patient’s left internal oblique muscle. A diagnosis of a lateral oblique muscle hematoma was made and the patient was treated conservatively. Conclusion Physicians should consider an oblique muscle hematoma during the initial differential diagnosis of pain in the lateral abdominal wall even in the absence of anticoagulant therapy or trauma.

    Assuming that the Hagedorn fluid composed of known particles and resonances with masses m <2 GeV obeys the first-order theory (Eckart) of relativistic fluid, we discuss the transport properties of QCD confined phase. Based on the relativistic kinetic theory formulated under the relaxation time approximation, expressions for bulk and shear viscosity in thermal medium of hadron resonances are derived. The relaxation time in the Hagedorn dynamical fluid exclusively takes into account the decay and eventually van der Waals processes. We comment on the in-medium thermal effects on bulk and shear viscosity and averaged relaxation time with and without the excluded-volume approach. As an application of these results, we suggest the dynamics of heavy-ion collisions, non-equilibrium thermodynamics and the cosmological models, which require thermo- and hydro-dynamics equations of state.

    Contrary to other claims, we argue that bulk viscosity associated with the interactions of non- relativistic particles with relativistic particles around the time of the grand unified theory (GUT) phase transition cannot lead to inflation. Simply put, the key ingredient for inflation, negative pressure, cannot arise due to the bulk-viscosity effects of a weakly interacting mixture of relativistic and nonrelativistic particles.

    We compute loop corrections to the effective action of a field theory on a five-dimensional $S_1/Z_2$ orbifold. We find that the quantum loop effects of interactions in the bulk produce infinite contributions that require renormalization by four-dimensional couplings on the orbifold fixed planes. Thus bulk couplings give rise to renormalization group running of brane couplings.

    Most complications after appendectomy occur within ten days;however,we report the unusual case of a suture granuloma 12 years after open appendectomy.The afebrile 75-year-old woman presented with a slightly painful palpable mass in the right lower abdomen.There was no nausea or vomiting and bowel movements were normal.She lost 10 kg during the 3 mo before presentation.The patient had undergone an appendectomy 12 years previously.Physical examination revealed a tender mass,10 cm in diameter,under the appendectomy scar.The preoperative laboratory findings,tumor markers and plain abdominal radiographs were normal.Multi-slice computed tomography scanning showed an inhomogenous abdominal mass with minimal vascularization in the right lower abdomen 8.6 cm×8 cm×9 cm in size which communicated with the abdominal wall.The abdominalwall was thickened,weak and bulging.The abdominalwall mass did not communicate with the cecumor the ascending colon.Complete excision of the abdominalwall mass was performed via median laparotomy.Histopathological examination revealed a granuloma with a central abscess.This case report demonstrates that a preoperative diagnosis of abdominal wall mass after open appendectomy warrants the use of a wide spectrum of diagnostic modalities and consequently different treatment options.

    • Aortic dissection occurs when the layers of the aorta separate as a result of extra luminal cavity of blood through an intimal tear. Dissection limited to the abdominal aorta is rare. Unfortunately, the appropriate management of dissecting aneurysm of abdominal aorta is not documented yet. A 43 years old man was admitted to Al-zahra hospital in Isfahan with sudden onset of periumbilical abdominal pain. CT scan confirmed infrarenal dissection of abdominal aorta. Performing laparotomy, aorta was repaired using bifurcate collagen-coated Dacron graft. Surgical intervention with synthetic graft is recommended in patients with dissecting aortic aneurysm of infrarenal segments where the extent of dissection is limited and accessible.

    Panitch, Howard B

    2015-01-01

    The abdominal wall is an integral component of the chest wall. Defects in the ventral abdominal wall alter respiratory mechanics and can impair diaphragm function. Congenital abdominal wall defects also are associated with abnormalities in lung growth and development that lead to pulmonary hypoplasia, pulmonary hypertension, and alterations in thoracic cage formation. Although infants with ventral abdominal wall defects can experience life-threatening pulmonary complications, older children typically experience a more benign respiratory course. Studies of lung and chest wall function in older children and adolescents with congenital abdominal wall defects are few; such investigations could provide strategies for improved respiratory performance, avoidance of respiratory morbidity, and enhanced exercise ability for these children.

    Analysis of the Pangu N-body simulation validates that bulk flow of halos follows Maxwellian distribution of which variance is consistent with prediction of linear perturbation theory of structure formation. We propose that consistency between observed bulk velocity and theories shall be examined at the effective scale as radius of spherical top-hat window function yielding the same smoothed velocity variance in linear theory as the sample window does. Then we compared some recently estimated bulk flows from observational samples with prediction of the $\\Lambda$CDM model we used, some results deviate the expectation at level of $\\sim 3\\sigma$ but the tension is not as severe as previously claimed. We disclose that bulk flow is weakly correlated with dipole of internal mass distribution, alignment angle between mass dipole and bulk flow has broad distribution but is peaked at $\\sim 30-50^\\circ$, meanwhile bulk flow shows little dependence on mass of halos used for estimation. In the simulation of box size $1h^...

  1. Abdominal ultrasonography in the diagnostic work-up in children with recurrent abdominal pain

    DEFF Research Database (Denmark)

    Wewer, Anne Vibeke; Strandberg, C; Pærregaard, Anders;

    1997-01-01

    We report on our experience with routine abdominal ultrasonography in 120 children (aged 3-15 years) with recurrent abdominal pain, in order to determine the diagnostic value of this investigation. Eight children (7%) revealed sonographic abnormalities: gallbladder stone (n = 2), splenomegaly (n...... = 1) and urogenital abnormalities (n = 5). The recurrent abdominal pain could be explained by these findings in only two (may be three) cases. CONCLUSION: The diagnostic value of abdominal ultrasonography in unselected children with recurrent abdominal pain is low. However, the direct visualization...... of the abdominal structures as being normal may be helpful to the parents and the child in their understanding and acceptance of the benign nature of recurrent abdominal pain....

    Full Text Available Abstract Objective: To determine the value of anterior displacement of the abdominal aorta, when present at any level or only at the level of the adrenal gland, contralateral to the mass, in diagnosing neuroblastoma on computed tomography or magnetic resonance imaging in children up to 7 years of age. Materials and Methods: Imaging examinations of 66 patients were classified by consensus as for the presence of anterior aorta displacement and were compared with the pathology report. Results: We found anterior abdominal aorta displacement in 26 (39.39% of the 66 patients evaluated. Among those 26 patients, we identified neuroblastoma in 22 (84.62%, nephroblastoma in 3 (11.54%, and Burkitt lymphoma in 1 (3.85%. The positive predictive value was 84.62%, and the specificity was 88.24%. The displacement of the aorta was at the adrenal level, contralateral to the mass, in 14 cases, all of which were attributed to neuroblastoma. Conclusion: When the abdominal aorta is displaced at the level of the adrenal gland, contralateral to the mass, it can be said that the diagnosis is neuroblastoma, whereas abdominal aorta displacement occurring at other abdominal levels has a positive predictive value for neuroblastoma of approximately 85%.

    A prospective study of all infrarenal abdominal aortic aneurysm (AAA) repairs both as electives and emergencies in Penang between January 1997 to December 2000 is presented. The objectives of the study were to determine the age, gender, racial distribution of the patients, the incidence, and risk factors and to summarize treatments undertaken and discuss the outcome. Among the races, the Malays were the most common presenting with infrarenal AAA. The mean age of patients operated was 68.5 years. Males were more commonly affected compared to females (12:1). Most infrarenal AAA repairs were performed as emergency operations, 33 cases (61.1%) compared to electives, 21 cases (38.9%). Total survival was 70.3% (elective 85.7%; emergency 57.6%). Mortality rate was 31.5% and the primary reason is the lack of operating time available for urgent operation and for treatment of concurrent disease states. Mycotic aneurysm with its triad of abdominal pain, fever and abdominal mass resulted in a significantly higher mortality (46.6%). Ninety six percent of the infrarenal AAA had transverse diameter greater than 6 cm. Morphologically 90.7% were fusiform AAA rather than saccular aneurysm (9.3%). Pulmonary complications (35.2%) were more common than cardiac complications (11.1%) possibly related to the urgent nature of the operation, smoking or history of pulmonary tuberculosis. Bleeding (14.8%) was the most common cause of mortality in ruptured mycotic infrarenal AAA.

    A 25-year-old woman presented with abdominal discomfort and weight loss. Sonography demonstrated a well defined, anechoic, cystic mass with posterior acoustic enhancement, internal thin septations, and a peripheral hypoechoic solid portion that had no increased blood flow on Doppler ultrasound. Contrast-enhanced CT revealed a cystic omental mass with internal thin septations and an enhancing solid portion which appeared as the hypoechoic solid portion on ultrasonography. A pathologic specimen demonstrated a pseudocyst containing serous fluid with gelatinous material. The solid component at the peripheral portion of the pseudocyst indicated caseous necrosis with multinucleated giant cells. This histologic finding was consistent with tuberculosis and supported the final diagnosis of omental pseudocyst caused by tuberculous peritonitis. Therefore, intraperitoneal pseudocyst with tuberculosis should be considered in the differential diagnosis of an intraperitoneal cystic mass in a young adult

    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.

    Full Text Available Candida endocarditis is an emerging infectious disease, usually involving patients with intravascular prosthetic devices, and associated with substantial morbidity and mortality. A 28-year-old primigravida at 32 weeks of gestation was admitted with low-grade fever and lower abdominal pain for 2 weeks. She had undergone open appendicectomy 2 months before admission. Echocardiogram showed a pedunculated 24 mm × 21 mm mass attached to the undersurface of anterior mitral leaflet near the tip and moderate mitral regurgitation. Repeated blood cultures showed growth of nonalbicans candida. She was immediately started on liposomal amphotericin and was taken up for surgery, but despite all efforts she succumbed to her illness.

    Contrary to other claims, we argue that, bulk viscosity associated with the interactions of nonrelativistic particles with relativistic particles around the time of the grand unified theory (GUT) phase transition cannot lead to inflation. Simply put, the key ingredient for inflation, negative pressure, cannot arise due to the bulk viscosity effects of a weakly-interacting mixture of relativistic and nonrelativistic particles. 13 refs., 1 fig.

Caso clínico: paciente masculino con antecedente de asma que acudió a consulta por abdomen agudo con probable apendicitis aguda; durante el protocolo de estudio se diagnosticó síndrome de Churg Strauss, con manifestaciones intestinales. Conclusión: el síndrome de Churg Strauss es una vasculitis poco frecuente que puede manifestarse con síntomas intestinales, como en este caso; es importante tenerlo en mente a la hora de los diagnósticos diferenciales. Existen pocos reportes con este síndrome asociado con abdomen agudo, todos ellos con mal pronóstico.

  14. Cosmological Solutions on Compactified AdS_5 with a Thermal Bulk

    CERN Document Server

    Rothstein, I Z

    2001-01-01

    This paper is an investigation of the effects of a thermal bulk fluid in brane world models compactified on AdS_5. Our primary purpose is to study how such a fluid changes the bulk dynamics and to compare these effects with those generated by matter localized to the branes. We find an exact cosmological solution for a thermally excited massless bulk field, as well as perturbative solutions with matter on the brane and in the bulk. We then perturb around these solutions to find solutions for a massive bulk mode in the limit where the bulk mass (m_B) is small compared to the AdS curvature scale and T< m_B. We find that without a stabilizing potential there are no physical solutions for a thermal bulk fluid. We then include a stabilizing potential and calculate the shift in the radion as well as the time dependence of the weak scale as a function of the bulk mass. It is shown that, as opposed to a brane fluid, the bulk fluid contribution to the bulk dynamics is controlled by the bulk mass.

    INTRODUCTION: Evidence for the effect of post-operative abdominal binders on post-operative pain, seroma formation, physical function, pulmonary function and increased intra-abdominal pressure among patients after surgery remains largely un-investigated. METHODS: A systematic review was conducted....... The PubMed, EMBASE and Cochrane databases were searched for studies on the use of abdominal binders after abdominal surgery or abdominoplasty. All types of clinical studies were included. Two independent assessors evaluated the scientific quality of the studies. The primary outcomes were pain, seroma...... to reduce seroma formation after laparoscopic ventral herniotomy and a non-significant reduction in pain. Physical function was improved, whereas evidence supports a beneficial effect on psychological distress after open abdominal surgery. Evidence also supports that intra-abdominal pressure increases...

    In Japanese Americans, intra-abdominal fat area measured by computed tomography is positively associated with the prevalence and incidence of hypertension. Evidence in other populations suggests that other fat areas may be protective. We sought to determine whether a change in specific fat depots predicts the development of hypertension. We prospectively followed up 286 subjects (mean age, 49.5 years; 50.4% men) from the Japanese American Community Diabetes Study for 10 years. At baseline, subjects did not have hypertension (defined as blood pressure ≥140/90 mm Hg) and were not taking blood pressure or glucose-lowering medications. Mid-thigh subcutaneous fat area, abdominal subcutaneous fat area, and intra-abdominal fat area were directly measured by computed tomography at baseline and 5 years. Logistic regression was used to estimate odds of incident hypertension over 10 years in relation to a 5-year change in fat area. The relative odds of developing hypertension for a 5-year increase in intra-abdominal fat was 1.74 (95% confidence interval, 1.28-2.37), after adjusting for age, sex, body mass index, baseline intra-abdominal fat, alcohol use, smoking status, and weekly exercise energy expenditure. This relationship remained significant when adjusted for baseline fasting insulin and 2-hour glucose levels or for diabetes mellitus and pre-diabetes mellitus classification. There were no significant associations between baseline and change in thigh or abdominal subcutaneous fat areas and incident hypertension. In conclusion, in this cohort of Japanese Americans, the risk of developing hypertension is related to the accumulation of intra-abdominal fat rather than the accrual of subcutaneous fat in either the thigh or the abdominal areas.

    The work includes the mechanical analysis of mechanical feeders and batchers that find application in various technological processes and industrial fields. Feeders are usually classified according to their design features into two groups: conveyor-type feeders and non-conveyor feeders. Batchers are used to batch solid bulk materials. Less frequently, they are used for liquids. In terms of a batching method, they are divided into volumetric and weighting batchers. Weighting batchers do not provide for sufficient batching accuracy. Automatic weighting batchers include a mass controlling sensor and systems for automatic material feed and automatic mass discharge control. In terms of operating principle, batchers are divided into gravitational batchers and batchers with forced feed of material using conveyors and pumps. Improved consumption of raw materials, decreased loss of materials, ease of use in automatic control systems of industrial facilities allows increasing the quality of technological processes and improve labor conditions. The batch feeder suggested by the authors is a volumetric batcher that has no comparable counterparts among conveyor-type feeders and allows solving the problem of targeted feeding of bulk material batches increasing reliability and hermeticity of the device.

    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.

    Abdominal wall hernias are a common condition. However, they may develop acute complications and require surgical correction in most cases. Hence, the correct radiological examination is requisite for an accurate diagnosis. A multi-detector row CT (MDCT) provides an accurate identification of the anatomy of the abdominal wall, precise hernia type, and helps in the detection of early signs of complication. We report various imaging features of abdominal wall hernias via a MDCT.

    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

    Objective: To review the clinical characteristics, treatment and prognoses of abdominal wall endometriosis(AWE).Methods: A retrospective study of 101 cases of AWE from 1992 to 2005 at Obstetric and Gynecologic Department of Peking Union Medical College Hospital was performed. Ninety-eight patients had a history of caesarean section. The mean age of the patients was (33.3±4.8) years and the average size of the mass was 1.5 cm. Abdominal wall mass associated pain during the menstrual cycle was noticed in 89.8% of the patients. The occurrence of AWE after caesarean section was 0.05% at our hospital. In patients without pelvic endometriosis or adenomyosis, 20.5% were presented with high CA125 >35 U/ml and the highest one was 93.4 U/ml. 92.1% of patients were diagnosed before surgery. 4 patients were administrated first in General Surgical Department with painless abdominal mass. Medication was adopted in 16 cases pre-operatively and 14 cases post-operatively.Results: The mean size of the resected mass was 4.2 cm, significantly larger than the estimation with palpation or ultrasonography, which was 0.8-1.2 cm (P=0.006, P<0.001). Pelvic endometriosis or adenomyosis was detected during the operation in 13 patients. One patient was diagnosed as atypical endometriosis by pathological examination in the beginning but transformed to be sarcoma finally. Ten patients recurred after surgery. 2 of them received medication and 5 of them received second operation.Conclusions: Ultrasonography can be used to evaluate the size of the mass and the infiltrative scope pre-operation. The serum CA125 is not specific for diagnosis of AWE. Complete eradication of the lesion with at least 1 cm beyond the edge of the mass is recommended as the primary treatment. Eradication should be considered also in recurrent cases. It may transform to malignant lesions after multiple recurrence.

    Objective To study the association between body mass index (BMI),waist circumference (WC) with body fat percent,and abdominal fat rate in overweight and obese pupils.Methods Using convenience sampling,two primary schools of Dongcheng district in Beijing were selected in May 2010.A total of 162 overweight and obese pupils graded from 2 to 5 who met the criteria of overweight and obese were recruited based on the physical exam record of the school medical department in April.Their physical measurements were taken to measure body fat percent (PBF),abdominal fat rate and visceral fat level and BMI was calculated.Independent-sample t test and Wilcoxon rank sum test were applied to analyze the gender differences.Correlation analysis was used to explore the association between the indexes of fat distribution (PBF,abdominal fat rate and visceral fat level) and BMI and WC.Univariate regression analysis was conducted to determine the variance of three indexes of fat distribution explained by the independent variables.Results The PBF of overweight and obese pupils was (43.62 ± 2.98) %,the abdominal fat rate of them was (28.06 ± 6.02) %,the visceral fat level of them was 7.51 ± 3.43,BMI was (23.41 ±2.83) kg/m2.WC,PBF and abdominal fat rate were (78.57 ± 7.76) cm,(42.36 ± 2.56) % and (26.47 ±5.39) % in boys and (73.34 ± 7.22) cm,(45.88 ± 2.26) %,(30.92 ± 6.07) % in girls.The difference in gender was significant (t values were-4.218,8.751,4.811,respectively,all P values < 0.01).The visceral fat level of boys and girls were 8.86 ± 3.42 and 5.09 ± 1.70,with significant difference (Z =-7.08,P <0.01).The correlation between PBF and BMI and the variance of PBF explained by BMI (r =0.563,R2 =31.7%) were stronger than them with WC (r =0.402,R2 =16.1%) (P < 0.01).The correlation between visceral fat levels and WC and the variance of visceral fat level explained by WC (r =0.723,R2 =57.3%) were higher than them with BMI (r =0.621,R2 =41.7%) (P < 0

  6. A focus on intra-abdominal infections

    Full Text Available Abstract Complicated intra-abdominal infections are an important cause of morbidity and are frequently associated with poor prognosis, particularly in higher risk patients. Well defined evidence-based recommendations for intra-abdominal infections treatment are partially lacking because of the limited number of randomized-controlled trials. Factors consistently associated with poor outcomes in patients with intra-abdominal infections include increased illness severity, failed source control, inadequate empiric antimicrobial therapy and healthcare-acquired infection. Early prognostic evaluation of complicated intra-abdominal infections is important to select high-risk patients for more aggressive therapeutic procedures. The cornerstones in the management of complicated intra-abdominal infections are both source control and antibiotic therapy. The timing and the adequacy of source control are the most important issues in the management of intra-abdominal infections, because inadequate and late control of septic source may have a negative effect on the outcomes. Recent advances in interventional and more aggressive techniques could significantly decrease the morbidity and mortality of physiologically severe complicated intra-abdominal infections, even if these are still being debated and are yet not validated by limited prospective trials. Empiric antimicrobial therapy is nevertheless important in the overall management of intra-abdominal infections. Inappropriate antibiotic therapy may result in poor patient outcomes and in the appearance of bacterial resistance. Antimicrobial management is generally standardised and many regimens, either with monotherapy or combination therapy, have proven their efficacy. Routine coverage especially against Enterococci and candida spp is not always recommended, but can be useful in particular clinical conditions. A de escalation approach may be recommended in patients with specific risk factors for multidrug

    One case of Behcet's disease with multiple aneurysms in both common carotid arteries and abdominal aorta is presented with brief review of the literatures. A 26-year-old woman had slowly enlarging pulsatile masses in both sides of neck and recurrent ulcerations in oral cavity and genitalia. One day prior to admission, aphasia, right facial nerve palsy and right hemiplegia suddenly developed. Brain CT showed acute infarction in left basal ganglia. Both Carotid Angiography and abdominal Aortography demonstrated multiple aneurysms in both common carotid arteries and abdominal aorta with organizing thrombi and thromboembolism of internal carotid artery.

    Full Text Available A rare case of blunt traumatic abdominal hernia is presented in which jejunal loops herniated through the abdominal wall. The patient had a serious motor vehicle accident seven years ago, while wearing the seat belt. He developed a traumatic hernia in the anterior lateral abdominal wall, which was operated, and relapsed after some months. The patient was reoperated and we observed the unattachment of the anterior lateral abdominal musculature from the ilium crest. After the hernial sac treatment, the defect was solved with the use of a polypropylene mesh. The postoperative evolution was good and four months later there were no signs of recurrence. Traumatic abdominal hernia remains a rare clinical entity, despite the increase in blunt abdominal trauma. Traumatic abdominal wall hernia falls into two general categories: small lower quadrant abdominal defects, typically the result of blunt trauma with bicycle handlebars, and larger abdominal wall defects related to motor vehicle accidents. The diagnosis may be often established by the physical examination alone. Conventional radiology and computerized tomography usefulness have been proved. In the vast majority of cases, early repair is recommended. The appropriate treatment is the reduction of the herniated bowel into the abdomen, the debridment of nonviable tissues, and a primary tension free closure of the detect.

    There are many medical causes of abdominal pain; abdominal epilepsy is one of the rarer causes. It is a form of temporal lobe epilepsy presenting with abdominal aura. Temporal lobe epilepsy is often idiopathic, however it may be associated with mesial temporal lobe sclerosis, dysembryoplastic neuroepithelial tumors and other benign tumors, arterio-venous malformations, gliomas, neuronal migration defects or gliotic damage as a result of encephalitis. When associated with anatomical abnormality, abdominal epilepsy is difficult to control with medication alone. In such cases, appropriate neurosurgery can provide a cure or, at least, make this condition easier to treat with medication. Once all known intra-abdominal causes have been ruled out, many cases of abdominal pain are dubbed as functional. If clinicians are not aware of abdominal epilepsy, this diagnosis is easily missed, resulting in inappropriate treatment. We present a case report of a middle aged woman presenting with abdominal pain and episodes of unconsciousness. On evaluation she was found to have an intra-abdominal foreign body (needle). Nevertheless, the presence of this entity was insufficient to explain her episodes of unconsciousness. On detailed analysis of her medical history and after appropriate investigations, she was diagnosed with temporal lobe epilepsy which was treated with appropriate medications, and which resulted in her pain being relieved.

    Objective: Myxofibrosarcoma (MFS) is a relatively rare tumor that is histologically characterized by myxoid stroma and spindle cell proliferation. This tumor most commonly arises as a slow growing, enlarging painless mass in the extremities of elderly patients. Methods: We report a case of a primary, low-grade MFS in the rectus abdominis muscle infiltrating the abdominal cavity of a 75-year-old man. Results: The patient underwent a wide excision of the right abdominal wall mass with a 3-cm surgical margin from the scar due to a biopsy. The tumor infiltrated the urinary bladder, peritoneum, and external iliac vessels. Twenty-six months after the initial operation, he had recurrences in his abdominal wall, urinary bladder, and right iliac vessels. Conclusions: To our knowledge, primary MFS of the muscle in the abdomen has not been documented previously. Although this case was histopathologically classified as a low-grade tumor, it infiltrated the abdominal cavity. The tumor is suspected to have penetrated the abdominal cavity below the linea arcuata, which lacks the posterior sheath of the rectus abdominis muscle; from there, it could easily spread without being blocked by any biological barriers.

    We consider Lorentzian correlators of local operators. In perturbation theory, singularities occur when we can draw a position-space Landau diagram with null lines. In theories with gravity duals, we can also draw Landau diagrams in the bulk. We argue that certain singularities can arise only from bulk diagrams, not from boundary diagrams. As has been previously observed, these singularities are a clear diagnostic of bulk locality. We analyze some properties of these perturbative singularities and discuss their relation to the OPE and the dimensions of double-trace operators. In the exact nonperturbative theory, we expect no singularity at these locations. We prove this statement in 1+1 dimensions by CFT methods.

    Bulk metallic glasses (BMGs) Fe–B–Y–Nb–Cu, 2 mm in diameter, were successfully annealed to become bulk nano-crystalline alloys (BNCAs) with α-Fe crystallite 11–13 nm in size. A ‘crystallization-and-stop’ model was proposed to explain this behavior. Following this model, alloy-design criteria were elucidated and confirmed successful on another Fe-based BMG Fe–B–Si–Nb–Cu, 1 mm in diameter, with crystallite sizes 10–40 nm. It was concluded that BNCAs can be designed in general by the proposed cr...

    2002-01-01

    Aorto-caval fistula (ACF) is a rare complication of abdominal aortic aneurysm. It occurs in 1-6% of cases. The classic diagnostic signs of an ACF (pulsatile abdominal mass with bruit and right ventricular failure) are present only in a half of the patients. The most common diagnostic imaging procedures like ultrasound and computed tomography often are not sufficient enough. This leads to the delay in diagnosis, which has a great impact on the results of operation. We report a case of a patient, who was treated before admission to the Clinic because of azotemia and oliguria suggesting renal failure.

    From 1962 to 1970 about 200 abdominal aortographies were performed in Department of Radiology of National Medical Center, Seoul, Korea, with percutaneous retrograde seldinger catheterization technique. The 200 cases of the abdominal aortography were analyzed as followings. 1) The sex ratio of all patients was 105 (52.5%) males to 95 (47.5%) females. And high incidence was noted in middle age group. (46 patients were from 30 years to 40 years of age) 2) Radiological findings were grouped as 62 (31%) vascular lesion, 113 (56.5%) visceral or other expanding lesions and 29 (14.5%) angiographically nonspecific findings. Total is over 200 due to double lesions in 4 patients. 3) The 62 vascular lesions were composed of 40 aortitis, 28 renal hypertension etc. a) The 40 aortitis was divided into 25 artherosclerotic and 15 nonspecific. The 15 nonspecific aortitis revealed segmental narrowing (2-4 cm) with collaterals. b) In 28 renal hypertension, 17 cases were combined with aortitis, but not in 11 cases (Pure renal hypertension), and 19 cases were unilateral. 4) The highest incidence in 113 (56.5%) visceral or other expanding lesions, was renal lesions (88 cases), and other lesions, such as 12 retroperitoneal masses, 9 liver and pancreatic masses were also noted. The 88 renal lesions were composed of 37 renal tbc, 17 hydronephrosis (excluding tbc hydro), Tumors, 10 cyst etc. a) The most significant findings of renal tuberculosis in renal arteriogrpahy was rarefaction of contrast staining in involved area which was noted in 32 cases (87%) out of 37 renal Tuberculosis. b) All 12 hypernephroma, 1 wilm's tumor, metastaic tumor from fibromyomata uteri revealed pathological vessels and tumor stainings, however these findings were not noted in 2 ureteral carcinoma involving renal pelvis. 5) No permanent complications arose after abdominal aortography.

    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 (PPregnancy did not seem to affect IAP in this population of cats, possibly due to subjects being in early stages of pregnancy.

    2016-01-01

    There is a growing request for measuring intra-abdominal pressure in critically ill patients with acute abdominal pain to be clarified. Summarizing the research results on measurement of vesical intra-abdominal pressure and analyzing the level of evidence were the purposes of this integrative literature review, carried out based on the databases LILACS, MEDLINE and PubMed, from 2005 to July 2012. Twenty articles were identified, in that, 12 literature reviews, 4 descriptive and exploratory studies, 2 expert opinions, one prospective cohort study and one was an experience report. The vesical intra-abdominal pressure measurement was considered gold standard. There are variations in the technique however, but some common points were identified: complete supine position, in absence of abdominal contracture, in the end of expiration and expressed in mmHg. Most research results indicate keeping the transducer zeroed at the level of the mid-axillary line at the iliac crest level, and instill 25mL of sterile saline. Strong evidence must be developed. RESUMO Em pacientes críticos com quadros abdominais agudos a esclarecer é crescente a solicitação da aferição da pressão intra-abdominal.

    Full Text Available BACKGROUND: Keeping abdominal surgery patients warm is common and warming methods are needed in power outages during natural disasters. We aimed to evaluate the efficacy of low-cost, low-power warming methods for maintaining normothermia in abdominal surgery patients. METHODS: Patients (n = 160 scheduled for elective abdominal surgery were included in this prospective clinical study. Five warming methods were applied: heated blood transfusion/fluid infusion vs. unheated; wrapping patients vs. not wrapping; applying moist dressings, heated or not; surgical field rinse heated or not; and applying heating blankets or not. Patients' nasopharyngeal and rectal temperatures were recorded to evaluate warming efficacy. Significant differences were found in mean temperatures of warmed patients compared to those not warmed. RESULTS: When we compared temperatures of abdominal surgery patient groups receiving three specific warming methods with temperatures of control groups not receiving these methods, significant differences were revealed in temperatures maintained during the surgeries between the warmed groups and controls. DISCUSSION: The value of maintaining normothermia in patients undergoing abdominal surgery under general anesthesia is accepted. Three effective economical and practically applicable warming methods are combined body wrapping and heating blanket; combined body wrapping, heated moist dressings, and heating blanket; combined body wrapping, heated moist dressings, and warmed surgical rinse fluid, with or without heating blanket. These methods are practically applicable when low-cost method is indeed needed.

    Full Text Available Cystic fibrosis (CF is a multisystem disease with a range of abdominal manifestations including those involving the liver, pancreas, and kidneys. Recent advances in management of the respiratory complications of the disease has led to a greater life expectancy in patients with CF. Subsequently, there is increasing focus on the impact of abdominal disease on quality of life and survival. Liver cirrhosis is the most important extrapulmonary cause of death in CF, yet significant challenges remain in the diagnosis of CF related liver disease. The capacity to predict those patients at risk of developing cirrhosis remains a significant challenge. We review representative abdominal imaging findings in patients with CF selected from the records of two academic health centres, with a view to increasing familiarity with the abdominal manifestations of the disease. We review their presentation and expected imaging findings, with a focus on the challenges facing diagnosis of the hepatic manifestations of the disease. An increased familiarity with these abdominal manifestations will facilitate timely diagnosis and management, which is paramount to further improving outcomes for patients with cystic fibrosis.

    AIM: To study the morphologic and cellular immunologic changes after homologous transplantation of the abdominal aorta in rats after programmed cryopreservation (-196°C).METHODS: Abdominal aorta was harvested from anesthetized Spraque Dawley (SD) rats for cryopreservation (group B) or immediate implantation (group A). The survival rates and apoptotic rates of aortic endothelial cells (ECs)were examined. The patency rates, histology and cellular immunologic changes of the abdominal aorta were examined on days 1, 3, 7, 14, 30, 60 after transplantation respectively.RESULTS: The survival rate of ECs after programmed cryopreservation was 90.1±1.79%, about 3.4% lower than that of uncryopreservation (93.5±1.96%). The apoptotic rates of ECs was increased after cryopreservation (7.15%vs 4.86%, P<0.05). The patency rate of group B was significantly higher than that of group A (91.6±12.9% vs 62.5±26.2%, P<0.01). CD4/CD8 ratio, TCR αβ and CD11b/CD18 ratio of group B were significantly lower than those of group A (P<0.05). Revivification of the cryopreserved abdominal aorta showed normal adventitia and intact smooth muscle cells.CONCLUSION: Cryopreservation can reduce homologous abdominal aortic antigenecity. Even if without administration of immunosuppressive agents, it is still feasible to implement homologous artery grafting in rats.

    Full Text Available Abstract Background To summarize the diagnostic and therapeutic experiences on the patients who suffered abdominal complications after cardiovascular surgery with cardiopulmonary bypass(CPB. Methods A total of 2349 consecutive patients submitted to cardiovascular surgery with CPB in our hospital from Jan 2004 to Dec 2010 were involved. The clinical data of any abdominal complication, including its incidence, characters, relative risks, diagnostic measures, medical or surgical management and mortality, was retrospectively analyzed. Results Of all the patients, 33(1.4% developed abdominal complications postoperatively, including 11(33.3% cases of paralytic ileus, 9(27.3% of gastrointestinal haemorrhage, 2(6.1% of gastroduodenal ulcer perforation, 2(6.1% of acute calculus cholecystitis, 3(9.1% of acute acalculus cholecystitis, 4(12.1% of hepatic dysfunction and 2(6.1% of ischemia bowel diseases. Of the 33 patients, 26 (78.8% accepted medical treatment and 7 (21.2% underwent subsequent surgical intervention. There were 5(15.2% deaths in this series, which was significantly higher than the overall mortality (2.7%. Positive history of peptic ulcer, advanced ages, bad heart function, preoperative IABP support, prolonged CPB time, low cardiac output and prolonged mechanical ventilation are the risk factors of abdominal complications. Conclusions Abdominal complications after cardiovascular surgery with CPB have a low incidence but a higher mortality. Early detection and prompt appropriate intervention are essential for the outcome of the patients.

    2014-01-01

    Management of chronic abdominal pain can be challenging. Sometimes patients fail to get adequate response from multiple medications and nerve blocks. We present a patient case report of chronic abdominal pain with a history of multiple surgeries managed successfully by neuromodulation of the transverse abdominis plane (TAP). The TAP block is a procedure in which local anesthetic is injected into the abdominal fascial plane that carries sensory nerves to the abdominal wall in order to block pain sensation. It has been shown to reduce postoperative pain and analgesic dependence after abdominal and gynecological surgeries. A 60-year-old woman presented to us for chronic abdominal pain for which medications provided little relief. She had an extensive history of abdominal surgeries and was also treated for lower back pain with surgery and less invasive procedures in the past. Under our care, she underwent 2 TAP blocks with almost complete resolution of her abdominal pain. Her pain, however, came back within a few of weeks of the procedures. Since our patient found pain relief from the TAP blocks, we proceeded with neurostimulation of the TAP for long-term pain relief. We placed a dorsal column stimulator 16 contact lead for lower back and leg pain and 8 contact leads placed in the TAP under ultrasound guidance. She has had multiple follow-ups since her TAP lead placement procedure with continued and near complete resolution of her abdominal pain. The TAP lead stimulation was helping her abdominal pain and the dorsal column lead stimulation was helping her back and leg pain.

    Background Exercise is one of the few treatments that provide significant improvements in chronic low back pain (CLBP). We developed an innovative exercise device for abdominal trunk muscles. This device can be used in a sitting or standing position and contains a built-in system to measure abdominal trunk muscle strength. We examined whether subjects can adequately use the device to perform the exercises and measure their abdominal trunk muscle strength. Methods We collected data on the body height, body weight, body mass index, and girth of 30 healthy male volunteers, and measured their grip power and trunk extensor muscle strength using a dynamometer. The volunteers performed a sit-up test as an indicator of trunk flexor muscle strength, and we measured their abdominal muscle strength using the device. We then evaluated the correlations between abdominal trunk muscle strength and anthropometric parameters as well as the strength of other muscles. In subsequent tests, 5 of the 30 subjects participated in two positron emission tomography (PET) series consisting of examinations after a resting period (control study) and during exercise (exercise study). For the exercise study, the subjects performed 2 sets of exercises for 20 minutes using the device before and after an injection of 18F-fluorodeoxyglucose (FDG). PET-computed tomography images were obtained 60 minutes after FDG injection in each study. We compared the skeletal muscle metabolism of the participants in both studies using the standardized uptake value. Results The muscle strength measured by the device and the 30-second sit-up frequency were correlated. FDG accumulation within the diaphragm and abdominal rectus muscles was significantly higher in the exercise study. Conclusion Our innovative exercise device facilitates a coordinated contraction of the abdominal trunk muscles at the anterior aspect and the roof of the core, and enables subjects to measure the strength of these muscles.

    Necrotizing dermohypodermitis is a severe and potential fatal infection of soft tissues. We report two cases of 39- and 41-year-old patients operated of abdominal dermolipectomy and liposculpture after bariatric surgery. Because of a body mass index (BMI) less than 35kg/m(2), and trouble of interpretation of the SFAR recommendations, we have not achieved antibiotics. These patients presented an abdominal necrotizing dermohypodermitis at Staphylococcus lugdunensis, requiring wide excision of necrosis in emergency. The suites have been favorable after surgical and medical care. Perineal proximity, skin and subcutaneous peeling appear to be significant risk factors for this pathology. We suggest if case of abdominal dermolipectomy preventive measures in skin preparation and systematic antibiotics regardless of BMI. Indeed, the risk of a necrotizing dermohypodermitis recalls the importance of rigorous prevention and early diagnosis.

    We report a case of a 33-year-old previously healthy Haitian immigrant with a 7-month history of abdominal pain, fever and ascites. He had a history of positive tuberculin skin test but never underwent treatment for latent tuberculosis (TB) infection. Initial examination showed abdominal distension. Abdominal CT scan showed mild ascites, abnormal soft tissue in the greater omentum and small bowel mesentery, retroperitoneal adenopathy, peritoneal thickening and dilated loops of small bowel. Paracentesis and thoracentesis were initially non-diagnostic. HIV testing was negative. The differential diagnosis included lymphoma and TB peritonitis. The omental mass was biopsied under ultrasound guidance, and histopathology revealed non-necrotising granulomas. Sputum cultures and omental biopsy cultures subsequently grew Mycobacterium tuberculosis, and a diagnosis was made of pulmonary TB with TB peritonitis. The patient responded well to the initiation of anti-TB treatment.

    Granular cell tumors (GCTs) are extremely rare mesenchymal neoplasms of Schwann cell origin. Malignant GCTs (MGCTs) comprise 0.5-2% of all GCTs. In the present report, we describe a case of a 66-year-old man with MGCT of the abdominal wall. The patient visited our hospital due to a recently growing palpable soft tissue mass in the abdominal wall. Computed tomography scan revealed a 4.3 × 4.1 × 2.9 cm sized mass arising from the left abdominal wall, which was contemplated as a desmoid tumor before surgical excision. Histopathological examination confirmed MGCT.

    Full Text Available Abdominal wall endometrioma is a condition rarely seen by surgeons. It represents a diagnostic challenge due to its similarity with other tumors. This entity occurs in fertile women and often appears two to five years after gynecological and obstetric surgical procedures. It must be considered when dealing with a cyclically painful nodule located in a laparotomy scar. The diagnosis is established by histological examination; most imaging tests determine the characteristics of the lesion, concomitant lesions and the intra-abdominal origin or location in the abdominal wall. The cases of two patients treated at the General Surgery Department of the María Eugenia González Comprehensive Diagnostic Center in the Capital District, Venezuela, are presented. Wide excision of the tissue and histological examination were performed, confirming the diagnosis. The postoperative course was uneventful. This case is presented given the rarity of this condition.

    This study was designed to evaluate the effects of four specific sit-up exercises on muscular activity of the rectus abdominis. Pairs of surface electrodes were placed unilaterally on four quadrants of the rectus abdominis, delimited by tendinous inscriptions, in four male subjects. Electromyographic (EMG) recordings were taken while the subjects performed four different abdominal exercises. Each abdominal exercise was hypothesized to have a specific effect on one of the four quadrants of the rectus abdominis. The four exercises analyzed were: 1) long lying crunch, 2) bent knee crunch, 3) leg raise, and 4) vertical leg crunch. Analysis of the standardized EMG recordings demonstrated no significant differences in the mean muscle activity between the four different quadrants, in the mean muscle activity between the four different exercises, and in interactions between the exercises and the quadrants of the rectus abdominis. We conclude that none of the four abdominal exercises studied are specific for strengthening individual muscle quadrants of the rectus abdominis.

    Background The effect of decompressive laparotomy on outcomes in patients with abdominal compartment syndrome has been poorly investigated. The aim of this prospective cohort study was to describe the effect of decompressive laparotomy for abdominal compartment syndrome on organ function and outcomes. Methods This was a prospective cohort study in adult patients who underwent decompressive laparotomy for abdominal compartment syndrome. The primary endpoints were 28‐day and 1‐year all‐cause mortality. Changes in intra‐abdominal pressure (IAP) and organ function, and laparotomy‐related morbidity were secondary endpoints. Results Thirty‐three patients were included in the study (20 men). Twenty‐seven patients were surgical admissions treated for abdominal conditions. The median (i.q.r.) Acute Physiology And Chronic Health Evaluation (APACHE) II score was 26 (20–32). Median IAP was 23 (21–27) mmHg before decompressive laparotomy, decreasing to 12 (9–15), 13 (8–17), 12 (9–15) and 12 (9–14) mmHg after 2, 6, 24 and 72 h. Decompressive laparotomy significantly improved oxygenation and urinary output. Survivors showed improvement in organ function scores, but non‐survivors did not. Fourteen complications related to the procedure developed in eight of the 33 patients. The abdomen could be closed primarily in 18 patients. The overall 28‐day mortality rate was 36 per cent (12 of 33), which increased to 55 per cent (18 patients) at 1 year. Non‐survivors were no different from survivors, except that they tended to be older and on mechanical ventilation. Conclusion Decompressive laparotomy reduced IAP and had an immediate effect on organ function. It should be considered in patients with abdominal compartment syndrome. PMID:26891380

    Full Text Available In South Asians, a unique obesity phenotype of high abdominal fat is associated with increased cardiovascular risk. Low cardiorespiratory fitness (CRF is associated with abdominal fat and an increased risk of cardiovascular disease. The purpose of this paper is to determine whether CRF as assessed by VO2 peak, in post-menopausal South Asian women, was associated with body fat distribution and abdominal fat. Physically inactive post-menopausal South Asian women (n = 55 from the Greater Vancouver area were recruited and assessed from January to August 2014. At baseline, VO2 peak was measured with the Bruce Protocol, abdominal fat with CT imaging, and body composition with dual energy X-ray absorptiometry. ANOVA was used to assess differences in subcutaneous abdominal adipose tissue (SAAT, visceral adipose tissue (VAT and total abdominal adipose tissue (TAAT between tertiles of CRF. Bivariate correlation and multiple linear regression analyses explored the association between VO2 peak with SAAT, VAT, TAAT and body composition. Models were further adjusted for body fat and body mass index (BMI. Compared to women in the lowest tertile of VO2 peak (13.8–21.8 mL/kg/min, women in the highest tertile (25.0–27.7 mL/kg/min had significantly lower waist circumference, BMI, total body fat, body fat percentage, lean mass, SAAT, VAT and TAAT (p < 0.05. We found VO2 peak to be negatively associated with SAAT, VAT and TAAT, independent of age and body fatness but not independent of BMI. Further research is necessary to assess whether exercise and therefore improvements in CRF would alter SAAT, VAT and TAAT in post-menopausal South Asian women.

  1. Unusual cause of acute abdominal pain in a postmenopausal woman: adnexal torsion

    2016-03-01

    Full Text Available Adnexal torsion is an infrequent but significant cause of acute lower abdominal pain in women. While adnexal torsion is generally considered in premenopausal women presenting with acute abdominal pain and a pelvic mass, it is a rare cause of acute abdominal pain during postmenopausal period. The diagnosis of adnexal torsion is often challenging due to nonspesific clinical, laboratory and physical examination findings. Causes of adnexal torsion is also different in premenopausal and postmenopausal women. While a simple functional cyst is often the cause of torsion in premenopausal women, it is more rarely the cause in postmenopausal women. Adnexal torsion is a surgical emergency. The surgery of adnexal torsion is performed either via conventional exploratory laparotomy or laparoscopic surgery. Adnexal torsion in postmenopausal women should be considered not only in the setting of sudden onset pain, but also in long-term abdominal discomfort. In this article, we presented a case with adnexal torsion that rarely cause acute abdominal pain in postmenopausal women. [Cukurova Med J 2016; 41(1.000: 167-170

    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.

    We present a case of perivascular epithelioid cell tumors (PEComas) in the abdominal cavity at the falciform ligament. A 30-yr-old Korean man visited to hospital for the evaluation of a growing, palpable abdominal mass. He had felt the mass growing over 6 months. There was no family or personal history of tuberous sclerosis. The resected specimen showed a mass of 8.0x7.0x5.5 cm in size. Histological examination showed sheets of spindle-to-epithelioid cells with clear-to-eosinophilic cytoplasm. Immunohistochemically, tumor cells were positive for HMB-4 (gp100) and smooth muscle actin. They were also positive for the S-100, which is a marker of neurogenic and melanocytic tumors. Patient was treated with radical resection of tumor without any adjuvant therapy. He is well and on follow-up visits without tumor recurrence.

    Full Text Available In 1999, a 50-year-old woman underwent ventriculoperitoneal (VP shunt surgery for hydrocephalus after subarachnoid hemorrhage. She was hospitalized for fever and recurrent systemic seizures in November 2006. Head computed tomography (CT showed only old changes. The seizures and fever were controlled by medicinal therapy. However, in December, her consciousness level suddenly decreased, and she showed progressive lower abdominal distension. Head CT showed marked ventriculomegaly, and abdominal CT showed a giant cystic mass at the shunt-tube tip in the lower abdominal cavity. Because thick pus was aspirated from the intra-abdominal mass, we diagnosed the patient with acute obstructive hydrocephalus due to an infected abdominal pseudocyst. Laparotomy and direct cyst drainage were performed, and antibiotic therapy against Streptococcus, the causative pathogen, was administered. The VP shunt tube was replaced. The postoperative course was uneventful, and postoperative CT showed hydrocephalus improvement and no pseudocyst recurrence. Abdominal pseudocysts, which are rare after VP shunt surgeries, usually occur after the subacute postoperative course in younger cerebral hemorrhagic cases. Our case was quite rare because the cyst developed in the chronic phase in an older patient and was caused by streptococcal infection. The cyst components should be examined before cyst drainage when choosing surgical strategies.

    The authors had offered the original estimated system with the points calculation, basing on analysis of the examination and treatment results in 150 patients, suffering abdominal sepsis. The system, alike others, includes not only determination of the inflammation factors and indices of endotoxicosis, but as well as those, concerning intraabdominal pressure, the anterior abdominal wall rigidity and the tissues elasticity. Among the important indices, needed to determine, were considered those, which categorize the syndrome of intraabdominal, intrathoracic and microregional hypertension as well as the mechanisms of endotoxicosis pathogenesis. The authors recommend to use the indices of pathological consequences of this two factors while doing assessment of the abdominal sepsis severity.

    2010-12-01

    Full Text Available OBJECTIVE: Obesity has been suggested as a risk factor for carpal tunnel syndrome (CTS. Previous studies on the association of CTS and obesity have generally considered body mass index (BMI. However, the relationships between CTS and waist circumference or waist-to-hip ratio (WHR, which are known as more sensitive measures for abdominal obesity, have not been studied previously. In this study, it was aimed to evaluate the role of BMI and abdominal obesity in patients with CTS. METHODS: Female patients who applied to the neurology outpatient clinics with pain, numbness, paresthesia, or dysesthesia in the hands were included. The patients were divided into two groups, according to the clinical evaluation, as CTS or non-CTS. CTS diagnosis was electrophysiologically confirmed in 44 patients. Thirty-one subjects who were not diagnosed as CTS electrophysiologically were recruited as the control group. Clinical findings, nerve conduction studies and anthropometric measurements (height, weight, BMI, hip circumference, waist circumference and WHR of CTS patients were compared with those of the control group. RESULTS: The CTS group had significantly higher BMI, waist circumference and WHR values compared to the control group (for each parameter, p< 0.0001. The rates of obesity in the CTS group were 55.8%, 47.7% and 34.9%, respectively, according to waist circumference, BMI and WHR measurements. In the CTS group, 16% of the patients, who were defined as non-obese according to BMI, were determined as obese according to waist circumference. In the CTS group, significant positive correlations were found between BMI and WHR and median-ulnar sensory interpeak latency of the fourth digit (r= 0.26, p< 0.05; r= 0.25, p< 0.05, respectively. CONCLUSION: In this study, it was found that abdominal obesity is an important risk factor for CTS, and nerve conduction may be affected by waist circumference, BMI and WHR. In addition to general obesity, abdominal obesity may

    Objective: A retrospective study to determine the success and complications of abdominal sacral colpopexy in correcting massive genital prolapse over an 8-year period between September 1989 and January 1997.Methods: The charts were reviewed for 3 patients with massive procidentia and 15 patients with symptomatic posthysterectomy vaginal vault prolapse, who desired preservation of sexual function and underwent abdominal sacral colpopexy with Marlex mesh at two community teaching hospitals.Results: In 16 of the 18 patients, one or more concurrent procedures were performed at the same time, including three Burch colpocystourethropexies and one Raz bladder neck suspension, which successfully controlled urinary stress incontinence. In three cases, staging procedures were done for ovarian neoplasia. There were no intraoperative complications. One patient developed a superficial abdominal wound infection, one patient had a deep venous thrombosis in her left leg 7 days postoperatively, and one patient experienced a 1 cm area of graft erosion 10 months postoperative requiring partial resection. Duration of follow-up has varied from 8 months to 5 years. One patient died 43 months after surgery of unrelated causes. No patients developed recurrent prolapse.Conclusions: Abdominal sacral colpopexy is a successful operation for the correction of prolapse. Serious complications are infrequent. Photographs of the technique and a review of the literature are presented.

    2016-01-01

    Bulk localized excited states in an AdS spacetime can be constructed from Ishibashi states with respect to the global conformal symmetry in the dual CFT. We study boundary two point functions of primary operators in the presence of bulk localized excitations in two dimensional CFTs. From two point functions in holographic CFTs, we observe causal propagations of radiations when the mass of dual bulk scalar field is close to the BF bound. This behavior for holographic CFTs is consistent with the locality and causality in classical gravity duals. We also show that this cannot be seen in free fermion CFTs. Moreover, we find that the short distance behavior of two point functions is universal and obeys the relation which generalizes the first law of entanglement entropy.

    Tuberous sclerosis is a complex autosomal-dominant neurocutaneous syndrome characterized by hamartomatous malformations of fibrous and connective tissues in various organs. Although various histologic types of soft-tissue masses can occur with tuberous sclerosis, we present a unique case of fibrous hamartoma of infancy presenting as large infiltrating cutaneous and subcutaneous masses in the abdominal wall in a 4-year-old boy with tuberous sclerosis. Although the co-occurrence of tuberous sclerosis and fibrous hamartoma of infancy is very rare, it should be considered in the differential diagnosis of subcutaneous soft-tissue masses found in children with tuberous sclerosis.

    2015-07-01

    Full Text Available Bulk metallic glasses (BMGs have desirable properties like high strength and low modulus, but their toughness can show much variation, depending on the kind of test as well as alloy chemistry. This article reviews the type of toughness tests commonly performed and the factors influencing the data obtained. It appears that even the less-tough metallic glasses are tougher than oxide glasses. The current theories describing the links between toughness and material parameters, including elastic constants and alloy chemistry (ordering in the glass, are discussed. Based on the current literature, a few important issues for further work are identified.

  15. Dark goo: Bulk viscosity as an alternative to dark energy

    CERN Document Server

    Gagnon, Jean-Sebastien

    2011-01-01

    We present a simple (microscopic) model in which bulk viscosity plays a role in explaining the present acceleration of the universe. The effect of bulk viscosity on the Friedmann equations is to turn the pressure into an "effective" pressure containing the bulk viscosity. For a sufficiently large bulk viscosity, the effective pressure becomes negative and could mimic a dark energy equation of state. Our microscopic model includes self-interacting spin-zero particles (for which the bulk viscosity is known) that are added to the usual energy content of the universe. We study both background equations and linear perturbations in this model. We show that a dark energy behavior is obtained for reasonable values of the two parameters of the model (i.e. the mass and coupling of the spin-zero particles) and that linear perturbations are well-behaved. There is no apparent fine tuning involved. We also discuss the conditions under which hydrodynamics holds, in particular that the spin-zero particles must be in local eq...

  16. Universal properties of bulk viscosity near the QCD phase transition

    CERN Document Server

    Karsch, F; Tuchin, K

    2008-01-01

    We extract the bulk viscosity of hot quark-gluon matter in the presence of light quarks from the recent lattice data on the QCD equation of state. For that purpose we extend the sum rule analysis by including the contribution of light quarks. We also discuss the universal properties of bulk viscosity in the vicinity of a second order phase transition, as it might occur in the chiral limit of QCD at fixed strange quark mass and most likely does occur in two-flavor QCD. We point out that a chiral transition in the O(4) universality class at zero baryon density as well as the transition at the chiral critical point which belongs to the Z(2) universality class both lead to the critical behavior of bulk viscosity. In particular, the latter universality class implies the divergence of the bulk viscosity, which may be used as a signature of the critical point. We discuss the physical picture behind the dramatic increase of bulk viscosity seen in our analysis, and devise possible experimental tests of related phenome...

    AIM: To analyze the experience within our hospital and to review the literature so as to establish the best means of diagnosis of abdominal tuberculosis.METHODS: The records of 11 patients (4 males, 7 females,mean age 39 years, range 18-65 years) diagnosed with abdominal tuberculosis in Harran University Hospital between January 1996 and October 2003 were analyzed retrospectively and the literature was reviewed.RESULTS: Ascites was present in all cases. Other common findings were weight loss (81%), weakness (81%), abdominal mass (72%), abdominal pain (72%), abdominal distension (63%), anorexia (45%) and night sweat (36%). The average hemoglobin was 8.2 g/dL and the average ESR was 50 mm/h (range 30-125). Elevated levels of cancer antigen CA-125were determined in four patients. Abdominal ultrasound showed abnormalities in all cases: ascites in all, tuboovarian mass in five, omental thickening in 3, and enlarged lymph nodes (mesenteric, para-aortic) in 2. CT scans showed ascites in all, pelvic mass in 5, retroperitoneal lymphadenopathy in 4, mesenteric stranding in 4, omental stranding in 3,bowel wall thickening in 2 and mesenteric lymphadenopathy in 2. Only one patient had a chest radiograph suggestive of a new TB lesion. Two had a positive family history of pulmonary TB. None had acid-fast bacilli (AFB) in the sputum and the tuberculin test was positive in only two. Laparotomy was performed in 6 cases, laparoscopy in 4 and ultrasoundguided fine needle aspiration in 2. In those patients subjected to operation, the findings were multiple diffuse involvement of the visceral and parietal peritoneum, white 'miliary nodules' or plaques, enlarged lymph nodes, ascites,'violin string' fibrinous strands, and omental thickening.Biopsy specimens showed granulomas, while ascitic fluid showed numerous lymphocytes. Both were negative for acid-fast bacilli by staining. PCR of ascitic fluid was positive for Mycobacterium tuberculosis ( M. tuberculosis) in all cases

    Purpose Using three separate models that included total body mass, total lean and total fat mass, and abdominal and thigh fat as independent measures, we determined their association with knee-joint loads in older overweight and obese adults with knee osteoarthritis (OA). Methods Fat depots were quantified using computed tomography and total lean and fat mass determined with dual energy x-ray absorptiometry in 176 adults (age = 66.3 yr., BMI = 33.5 kg·m−2) with radiographic knee OA. Knee moments and joint bone-on-bone forces were calculated using gait analysis and musculoskeletal modeling. Results Higher total body mass was significantly associated (p ≤ 0.0001) with greater knee compressive and shear forces, compressive and shear impulses (p < 0.0001), patellofemoral forces (p< 0.006), and knee extensor moments (p = 0.003). Regression analysis with total lean and total fat mass as independent variables revealed significant positive associations of total fat mass with knee compressive (p = 0.0001), shear (p < 0.001), and patellofemoral forces (p = 0.01) and knee extension moment (p = 0.008). Gastrocnemius and quadriceps forces were positively associated with total fat mass. Total lean mass was associated with knee compressive force (p = 0.002). A regression model that included total thigh and total abdominal fat found both were significantly associated with knee compressive and shear forces (p ≤ 0.04). Thigh fat was associated with the knee abduction (p = 0.03) and knee extension moment (p = 0.02). Conclusions Thigh fat, consisting predominately of subcutaneous fat, had similar significant associations with knee joint forces as abdominal fat despite its much smaller volume and could be an important therapeutic target for people with knee OA.

    In adults, the size of the left atria (LA) has important prognostic information. In obese adults, adolescents and children enlargement of LA have been observed. This has not been investigated on a population-based level in young children. We therefore assessed if total body fat mass (TBF......), abdominal fat, and body fat distribution were related to LA diameter. Cross-sectional study of 244 children (boys = 137 and girls n = 107) aged 8-11 years, recruited from an urban population-based cohort. Dual-energy X-ray absorptiometry (DXA) measured total lean body mass, TBF, and abdominal fat mass (AFM......). Body fat was also calculated as a percentage of body mass (BF%). Body fat distribution (AFM/TBF) was calculated. Echocardiography was performed with two-dimensional guided M-mode. LA diameter was measured and left ventricular mass (LVM) was calculated. Systolic blood pressure and diastolic blood...

    2010-01-01

    Full Text Available Isolated abdominal wall actinomycosis in the presence of an intrauterine contraceptive device (IUCD is extremely rare and only six such cases have been reported in the literature. We report a case where clinical and radiological examinations revealed a pseudotumor within the anterior abdominal wall. After being lost to follow-up, the patient presented two years later with the enlargement of the mass. The mass including the affected anterior abdominal wall was completely excised. The diagnosis of actinomycosis was established postoperatively by histopathological examination. Further questioning concerning her gynecological history revealed long-term use of the same IUCD. Surgical excision of the actinomycotic pseudotumour and removal of the IUCD followed by antibiotic therapy resulted in the full recovery of the patient.

    Chronic abdominal pain is a common clinical problem in primary care, and is usually referred to gastroenterologists or general surgeons. Although up to 20% of cases of idiopathic abdominal pain arise in structures of the abdominal wall, this is frequently overlooked as a possible cause. It includes pain arising from structures of the abdominal wall including skin, parietal peritoneum, cellular subcutaneous tissue, aponeuroses, abdominal muscles and somatosensorial innervation from lower dorsal roots. The diagnosis is based on anamnesis and physical examination. Carnett's sign is a simple maneuver that discriminates between parietal and visceral pain. Management with topical anesthesia is effective in a majority of patients and can help to confirm the diagnosis.

    Nongestational choriocarcinoma, a rare ovarian tumor, may present in young women with amenorrhea, abdominal distention, and elevated urine human chorionic gonadotropin (hCG), all of which may be mistaken for pregnancy. A 15-year-old Hispanic female, who reported no sexual activity, presented with 6 months of amenorrhea, abdominal pain, and progressive abdominal distension. Initially, suspicion of pregnancy was considered. Physical examination was significant for abdominal distension, but no uterine fundus or fetal anatomy could be palpated, and auscultation did not reveal any fetal heart sounds or bruits. Laboratory values showed elevated urine hCG, cancer antigen 125, and cancer antigen 19.9 levels but normal serum hCG level and was inconsistent with pregnancy. Computed tomographic scans revealed a large abdominal heterogeneous mass and pleural effusions. Salpingo-oophorectomy with total omentectomy and inversion appendectomy removed a 21 × 20.5 × 16.5-cm tumor. Pathological testing determined it to be a nongestational choriocarcinoma. This rare tumor is more common in the pediatric adolescent population than in adults. Surgical resection and chemotherapy often result in a positive prognosis. In female adolescent patients presenting with elevated hCG level, amenorrhea, and abdominal distention, choriocarcinoma should be considered, especially in those with no history of sexual activity or before menarche.

    The aim of this article is to present a novel method of evaluating the activity of lateral abdominal muscles using M-mode sonography. The method leads to calculation of the tissue deformation index, representing the percent change in lateral abdominal muscle thickness over time. The objectives of this study were as follows: (1) to establish the mean tissue deformation index values for individual lateral abdominal muscles; and (2) to establish the reliability of the tissue deformation index. In a group of 34 healthy young volunteers (mean age, 24.03 years; body mass, 68.89 kg; body height, 174.25 cm), the reflex response of the lateral abdominal muscles to postural perturbation in the form of rapid arm abduction was recorded in 2 series, with 6 repetitions each, and the tissue deformation index was calculated. The mean tissue deformation index values formed a gradient, increasing from deep to superficial lateral abdominal muscles: 0.06%/ms for transversus abdominis, 0.11%/ms for oblique internal, and 0.16 for oblique external muscles. The tissue deformation index values differed significantly among individual lateral abdominal muscles (all paired comparisons, P  0.8).

    Full Text Available Background: Blunt abdominal injury is a leading cause of death in trauma patients. A reliable test predicting intra-abdominal hemorrhage would be a novel method. The study objective was to assess the diagnostic accuracy of plasma ammonia in detection of intra-abdominal bleeding in patients with blunt abdominal trauma (BAT. Materials and Methods: In this observational study, all patients suffering from BAT, referred to our university teaching hospital included. The levels of ammonia were measured at the time of emergency department admission and 1 h after initial treatment. Demographic data, vital signs, and venous blood gas reports were recorded. Findings of contrast-enhanced abdominopelvic computed tomography scan and laparotomy were assumed as a gold standard for abdominal injuries. Results: A total of 104 patients was enrolled in the study. 15 patients (14.4% had intra-abdominal hemorrhage and the mean plasma ammonia level in this group was significantly higher than the other patients on admission time (101.73 ± 5.41 μg/dL vs. 47.36 ± 26.31 μg/dL, P < 0.001. On receiver-operator characteristic curve analysis, in cutoff point of 89 μg/dL, the sensitivity, specificity, positive and negative likelihood ratios were 100% (95% confidence interval [CI], 79.6-100, 93.26% (95% CI, 86-96.8, 14.83 (95% CI, 6.84-32.12, and 0, respectively. Conclusion: The study findings suggest the measurement of ammonia level at the time of admission in the patients with BAT would be a useful test predicting intra-abdominal hemorrhage. Furthermore, decrease in the ammonia level could be a useful marker for monitoring response to treatment in these patients.

In this article, the authors give an introduction to CT perfusion in abdominal imaging introducing technical aspects for calculation of perfusion parameters......Computed Tomography (CT) Perfusion is an evolving method to visualize perfusion in organs and tissue. With the introduction of multidetector CT scanners, it is now possible to cover up to 16 cm in one rotation, and thereby making it possible to scan entire organs such as the liver with a fixed...... table position. Advances in reconstruction algorithms make it possible to reduce the radiation dose for each examination to acceptable levels. Regarding abdominal imaging, CT perfusion is still considered a research tool, but several studies have proven it as a reliable non-invasive technique...

    10 patients with adrenal damage were observed during 2.5 years. It amounted 0.93% of all patients with closed abdominal injuries. The right adrenal gland was traumatized in all cases evidently due to it's compression between right lobe of liver and vertebral column. Adrenal damage is observed quite often in combination with injuries of right liver lobe, right kidney and retroperitoneal hematoma formation. 5 patients underwent laparotomy on account of intra-abdominal bleeding, but adrenal damage was never revealed. Ultrasound and tomographic semiotics of adrenal damage was worked out, which allowed ascertaining diagnosis in 80% on application of ultrasound study and in 100% at computer tomography. Injury of one adrenal gland was not accompanied by adrenal failure and did not require hormonal replacement therapy.

    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.

    Two cases illustrate the clinical manifestations and angiographic findings associated with segmental stenosis of the abdominal aorta. Such lesions represent the chronic occlusive stage of Takayasu's disease, a nonspecific inflammatory arteritis of uncertain etiology. While the disease is considered autoimmune, an infectious process may be involved. Complications typically associated with stenotic lesions of the abdominal aorta are secondary renal hypertension and ischemic symptoms secondary to vascular insufficiency. Surgical correction, the treatment of choice, has achieved excellent results for these well-localized lesions. Secondary renal hypertension was relieved by a spenorenal shunt and the disease has since been controlled with conservative management in the first patient. An aortofemoral bypass graft successfully alleviated the vascular insufficiency in the second patient, although the patient unfortunately expired from a refractory postoperative cardiac complication.

    Gravity of abdominal vessels traumatisms is secondary to multiple factors. It depends on the type of injured vessels, aetiology and associated lesions. Between September 1984 and March 1995, 22 abdominal vessel traumatisms in 16 patients (mean age: 39 years) were treated. At surgical exploration, 4 aortic and 2 renal vein lesions, 7 iliac artery and 3 renal artery contusions, 2 superior mesenteric artery dissections; 3 infra-renal vena cava ruptures and 1 superior mesenteric vein dilaceration were found. All lesions were caused by penetrant wounds secondary to firearm or blade injury or secondary to injuries due to ski or traffic accidents. In 5 cases, lesions were iatrogenic. There was no mortality in the post-operative period, 14 patients out of the 16 patients operated on have been followed during a period from 1 to 120 months.

    Abdominal cocoon,the idiopathic form of sclerosing encapsulating peritonitis,is a rare condition of unknown etiology that results in an intestinal obstruction due to total or partial encapsulation of the small bowel by a fibrocollagenous membrane.Preoperative diagnosis re quires a high index of clinical suspicion.The early clinical features are nonspecific,are often not recognized and it is difficult to make a definite pre-operative diagnosis.Clinical suspicion may be generated by the recurrent episodes of small intestinal obstruction combined with relevant imaging findings and lack of other plausible etiologies.The radiological diagnosis of abdominal cocoon may now be confidently made on computed tomography scan.Surgery is important in the management of this disease.Careful dissection and excision of the thick sac with the release of the small intestine leads to complete recovery in the vast majority of cases.

    2014-01-01

    Based on the IR-improved bulk holographic AdS/QCD model which provides a consistent prediction for the mass spectra of resonance scalar, pseudoscalar, vector and axial vector mesons, we investigate its finite temperature behavior. By analyzing the spectral function of mesons and fitting it with a Breit-Wigner form, we perform an analysis for the critical temperature of mesons. The back-reaction effects of bulk vacuum are considered, the thermal mass spectral function of resonance mesons is calculated based on the back-reaction improved action. A reasonable melting temperature is found to be $T_c \\simeq 150 \\pm 7$ MeV, which is consistent with the recent results from lattice QCD simulations.

    Full Text Available Duodenal diverticuli are acquired false diverticuli of unknown etiology. Although mostly asymptomatic, they can occasionally cause upper gastrointestinal hemorrhage, rarely with massive bleeding. In this report, we present (to the best of our knowledge the first reported case of duodenal diverticular bleeding, causing abdominal compartment syndrome. Albeit a rare event, duodenal diverticular bleeding should be included in the differential diagnosis of upper gastrointestinal bleeding. As with our case, a multidisciplinary approach to managing such patients is crucial.

    In the appropriate clinical setting, certain aspects of extranodal abdominal lymphoma, as revealed by current cross-sectional imaging techniques, should be considered potentially diagnostic and can hasten the diagnosis. In addition, diagnostic imaging in the context of biopsy-proven lymphoma can accurately stage the disease for its appropriate treatment. The purpose of this article was to illustrate the various imaging aspects of extranodal lymphoma in the abdomen. PMID:28057966

    For studying abdominal tuberculosis (TB) in Ahmadi, files off all patients admitted to our hospital with abdominal TB over 15 years (1981-1996) were reviewed. Nineteen patients are reported here. Young adults were predominant in our study. The non-Arab Asians were the most frequently affected group in relation to their population in Ahmadi, and Kuwaitis were the least frequently affected group. Abdominal pain, sweating, anorexia and fever were the most frequent presenting symptoms. Ascites and intestinal obstruction were the most frequent clinical presentations. Two patients presented with acute appendicitis and one patient had tuberculous pancreatitis. Abdominal lymph nodes, peritoneum, ileum and and caecum were the most frequently affected abdominal structures. We found laparoscopy very helpful in diagnosis of abdominal TB and we recommend it as the diagnostic method of choice. All our patients responded well to antituberculous chemotherapy. It should be kept in mind that abdominal TB still affects the indigenous and expatriate population of Kuwait.

    2013-12-09

    Focal epilepsy with ictal abdominal pain is an unusual partial epilepsy characterized by paroxysmal episodes of abdominal or visceral pain, disturbance of awareness and electroencephalographic abnormalities. We describe a new case of ictal abdominal pain in which gastrointestinal complaints were the only manifestation of seizures and review the previously described pediatric patients. In our patient clinical findings, ictal EEG abnormalities, and a good response to antiepileptic drugs allowed us to make a diagnosis of focal epilepsy with ictal abdominal pain. This is a rare epileptic phenomenon that should be suspected in patients with unexplained paroxysmal abdominal pain and migraine-like symptoms. We suggest that, after the exclusion of more common etiologies, focal epilepsy with ictal abdominal pain should be considered in patients with paroxysmal abdominal pain and ictal EEG abnormalities.

    2010-03-01

    Nanofluidics has emerged recently in the footsteps of microfluidics, following the quest for scale reduction inherent to nanotechnologies. By definition, nanofluidics explores transport phenomena of fluids at nanometer scales. Why is the nanometer scale specific? What fluid properties are probed at nanometric scales? In other words, why does 'nanofluidics' deserve its own brand name? In this critical review, we will explore the vast manifold of length scales emerging for fluid behavior at the nanoscale, as well as the associated mechanisms and corresponding applications. We will in particular explore the interplay between bulk and interface phenomena. The limit of validity of the continuum approaches will be discussed, as well as the numerous surface induced effects occurring at these scales, from hydrodynamic slippage to the various electro-kinetic phenomena originating from the couplings between hydrodynamics and electrostatics. An enlightening analogy between ion transport in nanochannels and transport in doped semi-conductors will be discussed (156 references).

    Spinor fields on 5-dimensional Lorentzian manifolds are classified, according to the geometric Fierz identities that involve their bilinear covariants. Based upon this classification that generalises the celebrated 4-dimensional Lounesto classification of spinor fields, new non-trivial classes of 5-dimensional spinor fields are, hence, found, with important potential applications regarding bulk fermions and their subsequent localisation on brane-worlds. In addition, quaternionic bilinear covariants are used to derive the quaternionic spin density, through the truncated exterior bundle. In order to accomplish a realisation of these new spinors, a Killing vector field is constructed on the horizon of 5-dimensional Kerr black holes. This Killing vector field is shown to reach the time-like Killing vector field at the spatial infinity, through a current 1-form density, constructed with the derived new spinor fields.

    Full Text Available Background. The patients with abdominal aortic calcification have a high risk of cardiocerebral events, but the pathways of them have not been reported so far. The goal of our study was to assess the structure and function of myocardium and to determine the morphological features of carotid artery atherosclerosis in patients with abdominal aortic calcification.Materials and methods. A total of 167 executive patients with peripheral arterial disease were enrolled in study. The study group included 85 patients with abdominal aortic calcification (men – 95.3 %; age median was – 66.6 ± 12. Control group included 82 patients without objective signs of abdominal aortic calcification. Abdominal aortic calcification was detected by CT imaging. All patients have undergone echocardiography and duplex scanning of carotid arteries.Results. Prevalence and severity of ischemic heart disease and cerebrovascular disease were statistically significant higher in patients with abdominal aortic calcification (91.7, 65.8 % vs. 67, 37.3 % (р < 0.01. We have found statistically significant differences between groupsin heart structure and function. A high left ventricular wall thickness (р < 0.01, left atrium dilation (р < 0.01 and enhanced of left ventricular mass (р < 0.05, ejection fraction reduction (р < 0.05 and more common diastolic dysfunction (р < 0.05 were determined inpatients with abdominal aortic calcification. An intima-media thickness of the common carotid artery was significantly higher in study group patients (1.38 ± 0.07 mm vs. 1.14 ± 0.06 mm (р < 0.001.Conclusion. Our findings suggested that abdominal aortic calcification is main reason of hypertrophy and dilation in the left heart due to enhanced peripheral resistance. Hypertrophy and dilation in the left heart is provided a high risk of cardiovascular events in patients withabdominal aortic calcification.

    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.

    Full Text Available La incidencia de embarazo ectópico ha aumentado en los últimos años hasta 1:43 recién nacidos. La variedad abdominal es una de las menos frecuentes, su incidencia es de 1:10mil  nacidos vivos. El 1% de los embarazos ectópicos son abdominales y la implantación en el epiplón es una rara entidad. Pueden clasificarse como primarios o secundarios en función de que se originen o no en la cavidad peritoneal. Se presenta un caso de embarazo abdominal primario, localizado en cara posterior del útero y recto, con edad gestacional 16 semanas y feto muerto, en una paciente de 25 años, atendida en el Hospital General “Dr. Ernesto Guevara de la Serna”, con antecedentes de salud, G0 P0 A0, con método anticonceptivo DIU retirado seis meses antes. Se trata de un embarazo abdominal primario, puesto que la anatomía patológica informó ausencia de invasión trofloblástica en la trompa izquierda. El manejo placentario en este caso no permitió realizar la remoción completa de la misma. El seguimiento ecográfico y  control de gonadotropinas evidenció una evolución favorable de la paciente, sin requerir manejo de metotrexate.

    Antecedentes: el angioedema hereditario es un trastorno inflamatorio episódico, que se hereda de manera autosómica dominante y se caracteriza por episodios de edema periférico. Los pacientes pueden tener edema de la pared de cualquier víscera hueca, incluido el intestino. Caso clínico: se comunica el caso de un paciente masculino de 33 años de edad, sin antecedentes de importancia, con dolor abdominal, localizado en el epigastrio, irradiado al cuadrante inferior derecho, acompañado de 5 vómitos. La tomografía abdominal mostró engrosamiento de la pared de la segunda y tercera porción del duodeno, con infiltración de grasa y líquido libre. Los exámenes de laboratorio mostraron: concentraciones bajas del complemento C4 (5.5 mg/dL) y actividad del inhibidor de C1 del complemento de 30%. Conclusiones: el angioedema hereditario es consecuencia de la deficiencia (tipo I) o disfunción (tipo II) del inhibidor C1 del complemento. El dolor abdominal asociado con angioedema es de inicio súbito, como dolor cólico, recurrente y de intensidad moderada. En la actualidad existen dos medicamentos aprobados por la Food and Drug Administration para el tratamiento de pacientes con esta afección.

    Full Text Available Introduction. Rupture of an abdominal aortic aneurysm (AAA is a potentially lethal state. Only half of patients with ruptured AAA reach the hospital alive. The alternative for open reconstruction of this condition is endovascular repair (EVAR. We presented a successful endovascular reapir of ruptured AAA in a patient with a number of comorbidities. Case report. A 60-year-old man was admitted to our institution due to diffuse abdominal pain with flatulence and belching. Initial abdominal ultrasonography showed an AAA that was confirmed on multislice computed tomography scan angiography which revealed a large retroperitoneal haematoma. Because of patient’s comorbidites (previous surgery of laryngeal carcinoma and one-third laryngeal stenosis, arterial hypertension and cardiomyopathy with left ventricle ejection fraction of 30%, stenosis of the right internal carotid artery of 80% it was decided that endovascular repair of ruptured AAA in local anaesthesia and analgosedation would be treatment of choice. Endovascular grafting was achieved with aorto-bi-iliac bifurcated excluder endoprosthesis with complete exclusion of the aneurysmal sac, without further enlargment of haemathoma and no contrast leakage. The postoperative course of the patient was eventless, without complications. On recall examination 3 months after, the state of the patient was well. Conclusion. The alternative for open reconstruction of ruptured AAA in haemodynamically stable patients with suitable anatomy and comorbidities could be emergency EVAR in local anesthesia. This technique could provide greater chances for survival with lower intraoperative and postoperative morbidity and mortality, as shown in the presented patient.

  11. Midgut malrotation with chronic abdominal pain

    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.

    Abdominal multi-organ transplantation including the liver, gallbladder, spleen, pancreas, kidneys, adrenal glands and gastrointestinal tract was attempted in 8 dogs. Each experiment was discontinued when the recipient deteriorated. Immersion hypothermia was introduced in both the donor and recipient until the esophageal temperature reached 27-30 degrees C. Whole abdominal organs of the donor were removed in an en-bloc fashion at 20 degrees C of the graft temperature after additional cooling by ice slush scattering into the abdominal cavity. Transplantation was carried out orthotopically in the following sequence: (1) the proximal aorta, (2) suprahepatic vena cava, (3) distal aorta, (4) infrahepatic vena cava. The alimentary tract was reconstructed by gastro-gastrostomy and colo-colostomy. The ureters were implanted in the bladder. Cold ischemic time of the graft was about 40 minutes. Heparin was not used throughout the procedure. Five out of eight dogs were alive for more than 24 hours and two of them survived for 60 hours with good recovery. No immunosuppressant was given. Though the result in the present study was far from satisfaction, the experiment may provide a possibility of a new experimental model for transplantation, especially regarding pathophysiology and interrelationship of the transplanted complex organs.

A forma hialino-vascular é caracterizada tipicamente por apresentar uma evolução clínica benigna, sem sintomas constitucionais (doença localizada. É geralmente tratada com cirurgia e/ou radioterapia. A doença multicêntrica apresenta sintomas sistêmicos. Ainda não há um consenso sobre qual a melhor abordagem terapêutica. Nós reportamos o caso de um homem de 47 anos de idade com uma massa abdominal e sintomas compressivos. Após ressecção cirúrgica parcial, os exames histopatológico e imuno-histoquímico revelaram doença de Castleman variante hialino vascular. Como as células foliculares eram CD20+, administramos rituximab (anticorpo monoclonal anti-CD20. A maioria dos casos revisados não consideram este tipo de abordagem, exceto no caso de doença de Castleman multicêntrica associada a infecção pelo HHV-8 e sarcoma de Kaposi. Geralmente considera-se o paciente curado após retirada cirúrgica da massa na doença localizada, mas realmente há um risco do paciente desenvolver um linfoma não-Hodgkin no seguimento a longo prazo.

    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.

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

    LENUS (Irish Health Repository)

    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.

    Diagnostic imaging is often an integral component in the workup of a pediatric patient with acute abdominal pain. The purpose of this study was to compare the diagnostic value of a three-view acute abdominal series (AAS) with that of a single supine view (SSV) in children with acute abdominal pain. All subjects aged ≤18 years that underwent an emergency three-view AAS examination for acute abdominal pain at a single urban hospital system were included. Retrospective evaluation of radiological diagnosis, number of radiological images, further imaging, management, and clinical outcomes was performed. "Positive" AAS studies were compared with corresponding SSV images for direct comparison of diagnostic value. Standard nonparametric statistical evaluation was performed. Five hundred forty-one AAS studies were included in the study. Greater than three radiographs were acquired in 29 % (153/541) of the subjects. Two hundred ninety-nine out of 541 AAS studies included a technically adequate SSV of the abdomen and pelvis. Most AAS examinations were categorized as negative (n = 485; 90 %). Of the 56 examinations initially classified as positive, there was no significant statistical difference between diagnostic accuracy between the AAS and SSV on retrospective evaluation. For pediatric subjects with nontraumatic acute abdominal pain, the yield of conventional radiographic study is exceedingly low. If required, a technically adequate single supine anteroposterior (AP) view of the abdomen and pelvis is sufficient for initial radiographic evaluation while reducing unnecessary radiation exposure to the patient.

    Objective: To study, by means of computed tomography, the repercussion of post-weaning dietary supplementation with soy oil or canola oil on the abdominal fat distribution in previously undernourished rats. Materials and methods: Dams submitted to 50% food restriction (FR) compared with dams receiving a standard diet (C). After weaning, undernourished rats received a diet supplemented with 19% soy oil (19% FR-soy) or 19% canola oil (19% FR-canola). Rats in the control group received a diet with 7% soy oil (7% C-soy) until the end of the experimental period. At the age of 60 days old, the rats were submitted to computed tomography for evaluation of total abdominal and visceral fat area. The rats' length and body mass were evaluated and, after their sacrifice, the abdominal fat depots were excised weighted. The data are reported as mean {+-} mean standard error, with p < 0.05 considered as significance level. Results: Rats in the group 19% FR presented similar length, body weight and visceral fat mass. As a whole, the evaluations have shower results significantly lower in relation to the control group (7% C-soy). However, computed tomography has found significant differences in abdominal fat distribution for the groups 19% FR-soy and 19% FR-canola. Conclusion: Computed tomography has demonstrated that the abdominal fat distribution may be dependent on the type of vegetable oil included in the diet. (author)

    Full Text Available Abstract Backround Sigmoid colon cancer metachronous metastases commonly occur in the liver and lungs with sporadic reports also to the spleen, stomach, thyroid gland, abdominal wall and upper urinary tract. This is a rare case of metachronous metastases invading the mesorectum and the abdominal wall. Case presentation A 72-year-old female underwent sigmoidectomy for stage I (T2N0 M0 sigmoid colon cancer in May 2008. In June 2009, an abdominal computed tomography scan revealed a tumor 2 cm in size at the lower anterior mesorectum and a second mass 2 cm in size at the anterior abdominal wall midline. Total colonoscopy showed no mucosal lesion. The serum carcinoembryonic antigen level was normal. A biopsy of the mesorectum tumor showed similar histologic characteristics with the primary tumor. Since no other site of recurrence was identified, an abdominoperineal resection was attempted. During the operation and after the removal of the incision recurrence, sinus bradycardia and signs of myocardial ischemia were noticed. A loop transverse colostomy was immediately perfomed and the operation was terminated. Postoperative cardiologic examination revealed an acute myocardium infract. Chemo-radiation of the mesorectum tumor and re-evaluation for surgical excision was decided. Conclusion Metachronous metastasis of the mesorectum from sigmoid colon cancer is extremely rare. Although patterns of lymphatic spread from rectal cancer to sigmoid colon have recently been demonstrated, there is no evidence of metachronous mesorectum invasion from sigmoid colon cancer. This could be the issue for future trials.

    Measures of body mass index (BMI) and waist circumference define general obesity and abdominal obesity respectively. While high BMI has been established as a risk factor for asthma in adults, waist circumference has seldom been investigated. To determine the association between BMI, waist circumference and incident asthma in adults, we conducted a prospective study (n=23,245) in a population living in Nord-Trøndelag, Norway in 1995-2008. Baseline BMI and waist circumference were measured and categorised as general obesity (BMI ≥30.0 kg·m(2)) and abdominal obesity (waist circumference ≥88 cm in females and ≥102 cm in males). Incident asthma was self-reported new-onset cases during an 11-yr follow-up period. Odds ratios for asthma associated with obesity were calculated using multivariable logistic regression. General obesity was a risk factor for asthma in females (OR 1.96, 95% CI 1.52-2.52) and males (OR 1.84, 95% CI 1.30-2.59). In females, after additional adjustment for BMI, abdominal obesity remained a risk factor for asthma development (OR 1.46, 95% CI 1.04-2.05). Abdominal obesity seems to increase the risk of incident asthma in females in addition to BMI, indicating that using both measures of BMI and waist circumference in females may be a superior clinical assessment for asthma risk than any measure alone.

    Obesity is a risk factor for surgical site infection (SSI) after abdominal procedures; however, data characterizing the risk of SSI in obese patients during abdominal procedures are lacking. We hypothesized that obesity is an independent risk factor for SSI across wound classes. We analyzed American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) data for 2011. We calculated body mass index (BMI), classifying patients according to National Institute of Health (NIH) BMI groups. We excluded records in which height/weight was not recorded and patients with BMI less than 18.5. We examined patients undergoing open abdominal procedures, performing univariate and multivariate analyses to assess the relative contribution of obesity to SSI. Study criteria were met by 89,148 patients. Obese and morbidly obese patients had significantly greater SSI rates in clean and clean-contaminated cases but not contaminated or dirty/infected cases. Logistic regression confirmed obesity and morbid obesity as being independently associated with the overall SSI development, specifically in clean [Obesity odds ratio (OR) = 1.757, morbid obesity OR = 2.544, P obesity OR = 1.239, morbid obesity OR = 1.287, P Obesity is associated with increased risk of SSI overall, specifically in clean and clean-contaminated abdominal procedures; this is independent of diabetes mellitus. Novel techniques are needed to reduce SSI in this high-risk patient population.

    Introducción: la presión intraabdominal es el estado de equilibrio de la presión de la cavidad abdominal en reposo y puede presentar cambios durante la ventilación mecánica o espontánea. El objetivo fue determinar la presión intraabdominal como predictor de cirugía en el paciente con dolor abdominal agudo. Métodos: se llevó a cabo un estudio de casos y controles anidado en una cohorte de pacientes con dolor abdominal agudo en el servicio de urgencias de un hospital de segundo nivel, en el periodo comprendido entre abril y diciembre de 2013. Se incluyeron 37 pacientes, todos fueron intervenidos quirúrgicamente con previa toma de la presión intraabdominal. Se formaron los grupos con el resultado del estudio anatomopatológico: con evidencia de proceso inflamatorio abdominal agudo (n = 28) y sin evidencia de proceso inflamatorio abdominal agudo (n = 9). Resultados: en los casos el 100 % presentó presión intraabdominal alta con una p = 0.01, RM: 5 (IC 95 %: 2.578-9.699). En los casos la media de la presión intraabdominal fue de 11.46 y en los controles de 9.2 (p = 0.183). Conclusiones: el dolor abdominal que requiere cirugía para su resolución tiene relación directa con una presión intraabdominal > 5 mmHg.

  2. If unnecessary computed tomography scans are performing for abdominal emergent pathologies in our radiology unit; retrospective study with comparing performed abdominal computed tomography scans with previous safer tests like ultrasound

    Background: Abdominal computed tomography (CT) is an imaging method that uses X-rays and may be done to look for cause of abdominal pain or swelling and fever, hernia, masses, infections, injury. Besides advantages, CT use ionizing radiation, which has the potential to cause cancer. So CT may still be done if the benefits greatly outweigh the risks and it is important to minimize unnecessary CT scans. While a CT scan may provide information, it is sometimes unlikely to change the treatment. T...

    2005-01-01

    We investigate the dynamics of a boundary field coupled to a bulk field with a linear coupling in an anti-de Sitter bulk spacetime bounded by a Minkowski (Randall-Sundrum) brane. An instability criterion for the coupled boundary and bulk system is found. There exists a tachyonic bound state when the coupling is above a critical value, determined by the masses of the brane and bulk fields and AdS curvature scale. This bound state is normalizable and localised near the brane, and leads to a tachonic instability of the system on large scales. Below the critical coupling, there is no tachyonic state and no bound state. Instead, we find quasi-normal modes which describe stable oscillations, but with a finite decay time. Only if the coupling is tuned to the critical value does there exist a massless stable bound state, as in the case of zero coupling for massless fields. We discuss the relation to gravitational perturbations in the Randall-Sundrum brane-world.

    In this note we present a simple, general prescription for coupling brane localized fields to bulk supergravity. We illustrate the procedure by considering 6D N=2 bulk supergravity on a 2D orbifold, with brane fields localized at the fixed points. The resulting action enjoys the full 6D N=2 symmetries in the bulk, and those of 4D N=1 supergravity at the brane positions. (orig.)

    We consider the gravity dual of the modular Hamiltonian associated to a general subregion of a boundary theory. We use it to argue that the relative entropy of nearby states is given by the relative entropy in the bulk, to leading order in the bulk gravitational coupling. We also argue that the boundary modular flow is dual to the bulk modular flow in the entanglement wedge, with implications for entanglement wedge reconstruction.

  7. Applications of bulk high-temperature superconductors

    Science.gov (United States)

    Hull, J. R.

    The development of high-temperature superconductors (HTS's) can be broadly generalized into thin-film electronics, wire applications, and bulk applications. We consider bulk HTS's to include sintered or crystallized forms that do not take the geometry of filaments or tapes, and we discuss major applications for these materials. For the most part applications may be realized with the HTS's cooled to 77 K, and the properties of the bulk HTS's are often already sufficient for commercial use. A non-exhaustive list of applications for bulk HTS's includes trapped field magnets, hysteresis motors, magnetic shielding, current leads, and magnetic bearings. These applications are briefly discussed in this paper.

    Full Text Available 【Abstract】Objective: Focused Abdominal Sono-graphy for Trauma (FAST is widely used for the detection of intraperitoneal free fluids in patients suffering from blunt abdominal trauma (BAT. This study aimed at assessing the diagnostic accuracy of this investigation in a designated trauma centre. Methods: This was a retrospective study of BAT pa-tients over a 6 year period seen in a trauma centre in Hong Kong. FAST findings were compared with laparotomy, ab-dominal computed tomography or autopsy findings, which served as the gold standard for presence of intraperi-toneal free fluids. The patients who did not have FAST or gold standard confirmatory test performed, had preexisting peritoneal fluid, died at resuscitation or had imcomplete docu-mentation of FAST findings were excluded. The performance of FAST was expressed as sensitivity, specificity, predic-tive values (PV, likelihood ratios (LR and accuracy. Results: FAST was performed in 302 patients and 153 of them were included in this analysis. The sensitivity, specificity, positive PV, negative PV, positive LR, negative LR and accuracy for FAST were respectively 50.0%, 97.3%, 87.0%, 84.6%, 18.8, 0.5 and 85.0%. FAST was found to be more sensitive in less severely injured patients and more specific in more severely injured patients. Conclusion: FAST is a reliable investigation in the initial assessment of BAT patients. The diagnostic values of FAST could be affected by the severity of injury and staff training is needed to further enhance its effective use.

    van der Meer, S B; Forget, P P; Arends, J W; Kuijten, R H; van Engelshoven, J M

    1990-01-01

    In order to investigate the diagnostic value of ultrasound in children with recurrent abdominal pain and to estimate the clinical relevance of rare organic causes of abdominal pain in these patients, we prospectively examined 93 children aged between 5.5 and 12 years by means of abdominal ultrasound. In 3 patients (3.2%) an anatomic abnormality was detected, which could not account for the abdominal pain. We conclude that many organic abnormalities, that could be diagnosed by ultrasound, are clinically irrelevant as a cause of recurrent abdominal pain in children and therefore ultrasound does not significantly contribute to the diagnosis. However, ultrasound can still play a role in the work-up of children with recurrent abdominal pain in avoiding unnecessary radiologic X-ray procedures.

  10. Recurrent abdominal pain: when an epileptic seizure should be suspected?

    Directory of Open Access Journals (Sweden)

    2002-01-01

    Full Text Available Recurrent episodes of abdominal pain are common in childhood. Among the diagnostic possibilities are migraine and abdominal epilepsy (AE. AE is an infrequent syndrome with paroxystic episodes of abdominal pain, awareness disturbance, EEG abnormalities and positive results with the introduction of antiepileptic drugs. We present one 6 year-old girl who had short episodes of abdominal pain since the age of 4. The pain was followed by cry, fear and occasionally secondary generalization. MRI showed tumor in the left temporal region. As a differential diagnosis, we report a 10 year-old boy who had long episodes of abdominal pain accompanied by blurring of vision, vertigo, gait ataxia, dysarthria, acroparesthesias and vomiting. He received the diagnosis of basilar migraine. In our opinion, AE is part of a large group (partial epilepsies and does not require a special classification. Pediatric neurologists must be aware of these two entities that may cause abdominal pain.

    2015-12-23

    Blunt abdominal trauma may cause severe intra-abdominal injuries, while clinical findings could be mild or absent directly after the trauma. The absence of clinical findings could mislead physicians into underestimating the severity of the injury at the primary survey, and inevitably leads to a delay in the diagnosis. The Blunt Abdominal Trauma in Children (BATiC) score may help to identify children who are at a high risk for intra-abdominal injuries in an early stage and requires additional tests directly. A case of a 10-year-old girl with a duodenal perforation after a blunt abdominal trauma is presented. A delay in diagnosis may lead to an increased morbidity and mortality rate. A low admission threshold for children with abdominal pain after a blunt trauma is recommended.

    In this case we presented a patient who were admitted to surgery department with complaints of abdominal pain and nausea. There were no pathological findings on physical examination, direct abdominal x-ray, chest radiograph and biochemical parameters. At proximal of the celiac trunk, it was shown approximately 3x2 cm in size fusiform aneurysmal dilatation on the patient%u2019s abdominal ultrasonography and turbulence, arterial flow on the patient%u2019s abdominal doppler ultrasonography subsequently. In abdominal computed tomography we detected dense calcifications, dilatation and hypodensities that may belong to a thrombus in the lumen superior mesenteric vein (SMV. At the same time, approximately 3.5 cm segment of trunk celiak we observed aneurysm dilatation which reaching 2 cm at the widest point. Celiac trunk aneurysm is a rare cause of abdominal pain and often noticed after the complicated, thus it must always be kept in mind in the differential diagnosis.

    Abdominal vascular syndromes are rare diseases. Although such syndromes vary widely in terms of symptoms and etiologies, certain imaging findings are characteristic. Depending on their etiology, they can be categorized as congenital - including blue rubber bleb nevus syndrome, Klippel-Trenaunay syndrome, and hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome) - compressive - including 'nutcracker' syndrome, median arcuate ligament syndrome, Cockett syndrome (also known as May-Thurner syndrome), and superior mesenteric artery syndrome. In this article, we aimed to illustrate imaging findings that are characteristic of these syndromes, through studies conducted at our institution, as well as to perform a brief review of the literature on this topic.

    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.

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.

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

    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

    2016-02-01

    The natural course of many abdominal aortic aneurysms (AAA) is to gradually expand and eventually rupture and monitoring the disease progression is essential to their management. In this publication, we review surrogate markers of AAA progression. AAA diameter remains the most widely used and important marker of AAA growth. Standardized reporting of reproducible methods of measuring AAA diameter is essential. Newer imaging assessments, such as volume measurements, biomechanical analyses, and functional and molecular imaging, as well as circulating biomarkers, have potential to add important information about AAA progression. Currently, however, there is insufficient evidence to recommend their routine use in clinical practice.

    To assess the outcomes of endovascular aortic aneurysm repair (EVAR) for the treatment of an abdominal aortic aneurysm in patients undergoing curative surgical treatment for concomitant abdominal malignancy. The study included 12 patients with abdominal neoplasia and an abdominal aortic aneurysm (AAA), which was treated by surgery and stent EVAR. The neoplasm consisted of the gastric, colorectal, pancreas, prostate, and gall bladder. The follow up period was 3-21 months (mean 11.8 months). All medical records and imaging analyses were reviewed by CTA and/or color Doppler US, retrospectively. Successful endoluminal repair was accomplished in all twelve patients. The mean interval time between EVAR and surgery was 58.6 days. Small amounts of type 2 endoleaks were detected in two patients (17%). One patient developed adult respiratory distress syndrome after Whipple's operation 20 days after surgery, which led to hopeless discharge. No procedure-related mortality, morbidity, or graft-related infection was noted. Exclusion of AAA in patients with accompanying malignancy show with a relatively low procedure morbidity and mortality. Hence, endoluminal AAA repair in patients with synchronous neoplasia may allow greater flexibility in the management of an offending malignancy

    The purpose of this study was to assess which modalities offered the best timing in the treatment of abdominal aortic aneurysms associated with other abdominal surgical diseases. From January 1984 to December 2002, 372 patients underwent surgery for abdominal aortic aneurysms, 350 men (94%) and 22 women (6%), mean age 72 years. Of these 10% were operated on urgently. The traditional open technique was used in 307 patients, and the endovascular method in the remaining 65 cases. In 40 patients (11%) we observed other associated abdominal diseases which were treated during the same operation in 34 cases (85%). We had three deaths in the 34 cases treated in the same operation (9%). In the remaining cases no perioperative mortality was registered. There were no cases of prosthesis infection. The mean hospital stay was 9 days. Simultaneous treatment appears, on the one hand, to carry an increased operative risk and increased mortality and, on the other, to present the advantage of having to perform only one surgical procedure. The advent of the endovascular method allows us to postpone the treatment of the associated disease without increasing the technical difficulty of the second operation.

    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.)

    Objectives: Trauma is among the leading causes of death. Medical management of blunt abdominal trauma (BAT) relies on judging patients for whom laparotomy is mandatory. This study aimed to determine BAT patients' signs, as well as paraclinical data, and to clarify the accuracy, sensitivity, specificity, positive and negative predictive value of clinical abdominal scoring system (CASS), a new scoring system based on clinical signs, in predicting whether a BAT patient needs laparotomy or not.Methods: Totally 400 patients suspected of BAT that arrived at the emergency department of two university hospitals in Tehran from March 20, 2007 to March 19, 2009 were included in this study. They were evaluated for age, sex,type of trauma, systolic blood pressure, Glasgow coma scale (GCS), pulse rate, time of presentation after trauma, abdominal clinical findings, respiratory rate, temperature, hemoglobin (Hb) concentration, focused abdominal sonography in trauma (FAST) and CASS.Results: Our measurements showed that CASS had an accuracy of 94%, sensitivity of 100%, specificity of 88%,positive predictive value of 90% and negative predictive value of 100% in determining the necessity of laparotomy in BAT patients. Moreover, in our analysis, systolic blood pressure, GCS, pulse rate, Hb concentration, time of presentation after trauma, abdominal clinical findings and FAST were also shown to be helpful in confirming the need for laparotomy (P<0.05).Conclusion: CASS is a promising scoring system in rapid detection of the need for laparotomy as well as in minimizing auxiliary expense for further evaluation in BAT patients, thus to promote the cost-benefit ratio and accuracy of diagnosis.

  11. Abdominal obesity, cardiometabolic risk and endocannabinoid system

    Directory of Open Access Journals (Sweden)

    G. Bittolo Bon

    2013-05-01

    Full Text Available Abdominal obesity is the most prevalent manifestation of metabolic syndrome and is of central importance in the definition of global cardiometabolic risk. Visceral adipose tissue releases a large number of bioactive mediators, which influence body weight homeostasis, insulin resistance, alterations in lipids, blood pressure, coagulation, fibrinolysis and inflammation, leading to increased risk of cardiovascular events and of type 2 diabetes. Lifestyle modification is the first-line approach to the management of abdominal obesity and metabolic syndrome. However for patients at higher risk, who cannot achieve an appreciable reduction in weight and in global cardiometabolic risk with lifestyle modification alone, an adjunctive long term pharmacotherapy should be considered. The endocannabinoid system activity regulates food intake and metabolic factors through cannabinoid-1 (CB1 receptor located in multiple sites, including hypothalamus and limbic forebrain, adipose tissue, skeletal muscle, liver and the gastrointestinal tract. Evidence suggests that CB1 receptor blockade offers a novel therapeutic strategy. Data from four phase III trials suggest that rimonabant, the first cannabinoid receptor inhibitor, modulates cardiometabolic risk factors, both through its impact on body weight and metabolic parameters such as HDL-cholesterol, tryglicerides, Hb1Ac, through direct pathways that are not related to weight loss.

    Full Text Available Abstract Background Idiopathic sclerosing encapsulating peritonitis (or abdominal cocoon is a rare cause of small bowel obstruction, especially in adult population. Diagnosis is usually incidental at laparotomy. We discuss one such rare case, outlining the fact that an intra-operative surprise diagnosis could have been facilitated by previous investigations. Case presentation A 56 year-old man presented in A&E department with small bowel ileus. He had a history of 6 similar episodes of small bowel obstruction in the past 4 years, which resolved with conservative treatment. Pre-operative work-up did not reveal any specific etiology. At laparotomy, a fibrous capsule was revealed, in which small bowel loops were encased, with the presence of interloop adhesions. A diagnosis of abdominal cocoon was established and extensive adhesiolysis was performed. The patient had an uneventful recovery and follow-up. Conclusion Idiopathic sclerosing encapsulating peritonitis, although rare, may be the cause of a common surgical emergency such as small bowel ileus, especially in cases with attacks of non-strangulating obstruction in the same individual. A high index of clinical suspicion may be generated by the recurrent character of small bowel ileus combined with relevant imaging findings and lack of other plausible etiologies. Clinicians must rigorously pursue a preoperative diagnosis, as it may prevent a "surprise" upon laparotomy and result in proper management.

    Non-invasive surface registration methods have been developed to register and track breathing motions in a patient's abdomen and thorax. We evaluated several different registration methods, including marker tracking using a stereo camera, chessboard image projection, and abdominal point clouds. Our point cloud approach was based on a time-of-flight (ToF) sensor that tracked the abdominal surface. We tested different respiratory phases using additional markers as landmarks for the extension of the non-rigid Iterative Closest Point (ICP) algorithm to improve the matching of irregular meshes. Four variants for retrieving the correspondence data were implemented and compared. Our evaluation involved 9 healthy individuals (3 females and 6 males) with point clouds captured in opposite breathing phases (i.e., inhalation and exhalation). We measured three factors: surface distance, correspondence distance, and marker error. To evaluate different methods for computing the correspondence measurements, we defined the number of correspondences for every target point and the average correspondence assignment error of the points nearest the markers.

    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.)

    Full Text Available BACKGROUND Abdominal wound dehiscence is a preventable complication, but is still seen. When present, it poses problem in the management of the case, increases the morbidity and mortality of the patient. The present study is a prospective study done from January 2010-May 2016 with an objective to find out the incidence of wound dehiscence, the most common pathologies associated with dehiscence and to find out the statistical significance of the difference risk factors causing wound dehiscence and to evaluate the role of tension sutures in prevention of wound dehiscence. MATERIALS AND METHODS 291 major laparotomies were followed from January 2010-September 2016. There were 21 cases of dehiscence and from the remaining 270 cases, 58 patients were chosen as controls who underwent the same procedure, but without dehiscence. 15 factors were analysed and compared between the dehiscence and control groups. RESULTS The incidence was found to be 7.2%. Peritonitis was the most common pathology. The significant factors were age more than 50, wound infection. Tension suture application has shown to reduce the incidence of wound dehiscence. CONCLUSIONS  Intra-abdominal sepsis (peritonitis increases the incidence of wound dehiscence.  Age >50, Uraemic, Jaundiced, Obesity, Malnutrition increases the incidence of wound dehiscence.  Wound infection was a highly significant factor having 8 times more risk of dehiscence.

    Results of surgical treatment of 201 patients, suffering abdominal sepsis (AS), which have occurred after operations on abdominal organs, were analyzed. Expediency of application of modern scales for the patients state severity estimation, prognostic sign-posts and dynamic of the pathological process course in every patient was substantiated. Existing systems of prognostication (APACHE II, SOFA, MODS) are applied restrictedly for diagnosis of infection in patients, what demands relaparotomy performance in presence of clinical signs of intraabdominal infection, which persists. For prognostication of the treatment result and determination of indications for relaparotomy conduction in patients, suffering severe AS and infectious-toxic shock (ITSH), the most informative is application of the Manheim's index of peritonitis together with analysis of clinico-laboratory indices for formation of groups of patients in risk, to whom reoperation is indicated. Advantages of relaparotomy "on demand" conduction were proved in comparison with "programmed" relaparotomy during the staged surgical treatment of patients, suffering severe AS and ITSH. Complex surgical treatment with substantiation of indications and choice of adequate method of intervention secures improvement of the treatment results in these severely ill patients.

    Full Text Available To clarify the incidence, background, and progress of hepatic infarction following interventional procedures, cases of hepatic infarction following interventional procedures at our department during the last decade were identified by reviewing the clinical records of 1982 abdominal angiography and interventional procedures and records of abdominal CT. Nine episodes (0.5% in 8 patients were identified as hepatic infarction following an interventional procedure. Five episodes were preceded by embolization of the hepatic or celiac artery at emergency angiography for postoperative bleeding with hemorrhagic shock. Three episodes followed the elected interventional procedure for hepatocellular carcinoma, and the remaining episode occurred after 12 months of chemoinfusion through an indwelling catheter in the hepatic artery and portal vein. Hepatic arterial occlusion in all episodes and portal venous flow abnormality in 5 episodes were observed on angiography. Four patients whose liver function was initially impaired died of hepatic infarction, although the extent of the disease on CT did not appear to be related to the mortality. Multiple risk factors, including arterial insufficiency, were observed in each patient. The incidence of hepatic infarction following interventional procedures in this series was low but sometimes fatal, and occurred most frequently in emergency embolization in hemorrhagic shock.

    Subjective feelings of fatigue were assessed before operation and 10, 20 and 30 days after uncomplicated elective abdominal surgery in 16 otherwise healthy patients, using a constructed fatigue scale model. In addition, all patients had an orthostatic stress test performed at the same times. Six of the patients also underwent a bicycle ergometer test measuring heart rate and oxygen consumption. Subjective feelings of fatigue were increased (P less than 0.01) at all three postoperative observations, and only 5 of 16 patients returned to their preoperative level. The increased subjective feeling of fatigue correlated positively (RS = 0.53, P less than 0.001) with the increased pulse rate seen during orthostatic stress after operation. Heart rate was about 5 per cent higher (n.s.) after operation when bicycling at the same work loads, while oxygen consumption decreased by about 2 per cent (P less than 0.01) at all three postoperative bicycle tests. It is concluded that even electric uncomplicated abdominal surgery is followed by a pronounced feeling of fatigue, which may persist 1 month after surgery in about one-third of patients. The fatigue scale model seems applicable for future studies on the pathogenesis and treatment of the postoperative fatigue syndrome.

    Full Text Available Context Intra-abdominal sepsis has significant morbidity and mortality. In the developed world, there are many common causes originating from the lower gastrointestinal tract including diverticular disease, appendicitis, perforated cancers, and inflammatory bowel disease. It has a high cost and is associated with high levels of significant morbidity and mortality. Management options include radiologic drainage and surgical options include resection for more widespread sepsis. Laparoscopic surgery has increased and has been useful in elective setting. Its use in the emergency setting is less evaluated. Evidence Acquisition Evidence was acquired by searching online medical databases including Pubmed, Medline and Embase. Results Laparoscopic surgery has been shown to have a role in the acute setting. Studies show it has become the gold standard in the appendicitis. High quality Randomized controlled trials are in short supply but observational and cohort studies have shown equivalence and with increasing experience complication rates are reduced. Evidence is also increasing in the management of diverticular disease, crohn’s and ulcerative colitis as well as post-operative complication management and acute presentations of colorectal cancer. Conclusions Laparoscopic surgery is feasible in the management of intra-abdominal sepsis. It has become the new accepted standard in the management of appendicitis, and is safe, feasible and increasing in the management of complex diverticular disease, acute IBD and colorectal cancer in the emergency and post-operative setting.

    Trichobezoar represents a mass of swallowed hair inside the stomach. Here we report a 17-year-old girl who presented in our department with symptoms of gastric ulcer. Ultrasound examination followed by upper endoscopy revealed a large trichobezoar in the stomach with simultaneous gastric perforation. Laparoscopy also revealed a penetration into the anterior abdominal wall accompanied by abscess at this level. We performed a laparoscopic gastrotomy with trichobezoar extraction and laparoscopic treatment of perforation and abdominal wall abscess. The postoperative evolution was normal and the patient was discharged on the fifth postoperative day. We show that laparoscopic approach may be safely used in the treatment of the large gastric complicated trichobezoar. Several laparoscopic approaches were described for the treatment of tricobezoar and its complications but as far as we know this is the first report of laparoscopic treatment of large tricobezoar and associate gastric perforation.

    Cylindrically symmetric non-static space–time is investigated in the presence of bulk stress given by Landau and Lifshitz. To get a solution, a supplementary condition between metric potentials is used. The viscosity coefficient of the bulk viscous fluid is assumed to be a power function of mass density whereas the coefficient of shear viscosity is considered as proportional to the scale of expansion in the model. Also some physical and geometrical properties of the model are discussed.

    The bulk viscosity is calculated for hadron matter produced in heavy-ion collisions, being described in the relaxation time approximation within the relativistic mean-field-based model with scaled hadron masses and couplings. We show how different approximations used in the literature affect the result. Numerical evaluations of the bulk viscosity with three considered models deviate not much from each other confirming earlier results.

    Objective To identify an optimal imaging strategy for the accurate detection of urgent conditions in patients with acute abdominal pain. Design Fully paired multicentre diagnostic accuracy study with prospective data collection. Setting Emergency departments of two university hospitals and four large teaching hospitals in the Netherlands. Participants 1021 patients with non-traumatic abdominal pain of >2 hours’ and <5 days’ duration. Exclusion criteria were discharge from the emergency department with no imaging considered warranted by the treating physician, pregnancy, and haemorrhagic shock. Intervention All patients had plain radiographs (upright chest and supine abdominal), ultrasonography, and computed tomography (CT) after clinical and laboratory examination. A panel of experienced physicians assigned a final diagnosis after six months and classified the condition as urgent or non-urgent. Main outcome measures Sensitivity and specificity for urgent conditions, percentage of missed cases and false positives, and exposure to radiation for single imaging strategies, conditional imaging strategies (CT after initial ultrasonography), and strategies driven by body mass index and age or by location of pain. Results 661 (65%) patients had a final diagnosis classified as urgent. The initial clinical diagnosis resulted in many false positive urgent diagnoses, which were significantly reduced after ultrasonography or CT. CT detected more urgent diagnoses than did ultrasonography: sensitivity was 89% (95% confidence interval 87% to 92%) for CT and 70% (67% to 74%) for ultrasonography (P<0.001). A conditional strategy with CT only after negative or inconclusive ultrasonography yielded the highest sensitivity, missing only 6% of urgent cases. With this strategy, only 49% (46% to 52%) of patients would have CT. Alternative strategies guided by body mass index, age, or location of the pain would all result in a loss of sensitivity. Conclusion Although CT is the most

    This study determined the prevalence of overweight, obesity, and abdominal obesity in the Portuguese adults and examined the relationship between above mentioned prevalences and educational level. Body mass, stature, and waist circumference were measured in a representative sample of the Portuguese population aged 18–103 years (n = 9,447; 18–64 years: n = 6,908; ≥65 years: n = 2,539). Overweight and obesity corresponded to a body mass index ranging between 25–29.9 kg/m2 and ≥30 kg/m2, respectively. Abdominal obesity was assessed as >102 cm for males and >88 cm for females. After adjusting for educational level, the combined prevalences of overweight and obesity were 66.6% in males and 57.9% in females (18–64 years). Respective values in older adults (≥65 years) were 70.4% for males and 74.7% for females. About 19.3% of adult males and 37.9% of adult females presented abdominal obesity. Correspondent values in older adults were 32.1%, for males, and 69.7%, for females. In adults, low educational level was related to an increased risk for overweight (OR = 2.54; 95% CI: 2.08–3.09), obesity (OR = 2.76; 95% CI: 2.20–3.45), and abdominal obesity (OR = 5.48; 95% CI: 4.60–6.52). This reinforces the importance of adjusting public health strategies for educational level. PMID:23118905

    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.

    The hot Neptune orbiting around GJ 436 is a unique example of an intermediate mass planet. Its close-in orbit suggests that the planet has undergone migration and its study is fundamental to understanding planet formation and evolution. As it transits its parent star, it is the only Neptune-mass extrasolar planet of known mass and radius, being slightly larger and more massive than Neptune (M=22.6 M_Earth, R=4.19R_Earth). In this regime, several bulk compositions are possible: from an Earth-like core with a thick hydrogen envelope to a water-rich planet with a thin hydrogen envelope comprising a Neptune-like structure. We combine planet-structure modeling with an advanced planet-formation model to assess the likelihood of the different possible bulk compositions of GJ 436 b. We find that both an envelope-free water planet ("Ocean planet") as well as a diminute version of a gaseous giant planet are excluded. Consisting of a rocky core with a thick hydrogen/helium envelope, a "dry" composition produces not only...

  11. Fiber architecture of canine abdominal muscles.

    2002-02-01

    During respiration, abdominal muscles experience loads, not only in the muscle-fiber direction but also transverse to the fibers. We wondered whether the abdominal muscles exhibit a fiber architecture that is similar to the diaphragm muscle, and, therefore, we chose two adjacent muscles: the internal oblique (IO), with about the same muscle length as the diaphragm, and the transverse abdominis (TA), which is twice as long as the diaphragm. First, we used acetylcholinesterase staining to examine the distribution of neuromuscular junctions on both surfaces of the TA and IO muscles in six dogs. A maximum of four irregular bands of neuromuscular junctions crossed the IO, and as many as six bands crossed the TA, which is consistent with a discontinuous fiber architecture. In six additional dogs, we examined fiber architecture of these muscles by microdissecting 103 fascicles from the IO and 139 from the TA. Each fascicle contained between 20 and 30 muscle fibers. The mean length of nonspanning fibers (NSF) ranged from 2.8 +/- 0.3 cm in the IO to 4.3 +/- 0.5 cm in the TA, and the mean length of spanning fibers ranged from 4.3 +/- 0.5 cm in the IO to 7.6 +/- 1.4 cm in the TA. NSF accounted for 89.6 +/- 1.5% of all fibers dissected from the IO and 99.1 +/- 0.2% of all fibers dissected from the TA. The percentage of NSF with both ends tapered was 6.2 +/- 1.0 and 41.0 +/- 2.3% for IO and TA, respectively. These data show that fiber architecture in either IO or TA is discontinuous, with much more short-tapered fibers in the TA than in the IO. When abdominal muscles are submaximally activated, as during both normal expiration and maximal expiratory efforts, muscle force could be transmitted to the cell membrane and to the extracellular intramuscular connective tissue by shear linkage, presumably via structural transmembrane proteins.

    2005-07-01

    Laparoscopy is a minimally invasive procedure that has applications as a diagnostic, therapeutic and prognostic technique. Specialized equipment is necessary to perform equine laparoscopy, and there is a large range of instruments, both disposable and non-disposable available. Laparoscopic procedures described include ovariectomy, cryptorchidectomy, adhesiolysis and herniorrhaphy. Laparoscopy can be performed in a standing or dorsally recumbent position, depending on surgeon preference, patient status and the procedure to be performed. Stapling equipment is frequently used in gastrointestinal surgery in horses. Advantages include decreased surgical time and a decrease in the risk of contamination. Stapling equipment is often used in creating anastomoses, both in the large and small intestines, as well as in vessel ligation. New surgical techniques intended to decrease adhesion formation include the use of carboxymethylcellulose and bioresorbable patches. Indwelling abdominal drains can be used for peritoneal lavage following surgery and also appear to decrease the risk of adhesion formation. Improvements in post-operative care, including the treatment of post-operative ileus and endotoxaemia can significantly improve the outcome of horses that have undergone surgery for abdominal disorders. Recommendations for the use of prokinetic agents in horses with ileus vary widely. Prokinetic agents include local anaesthetics, macrolide antimicrobials, cholinergic agonists and dopamine antagonists. Endotoxaemia is common in horses following surgery for gastrointestinal disorders. The antibiotic polymyxin B binds to the circulating endotoxin molecule, decreasing its half-life in the intra-vascular space and reducing associated inflammation. This drug appears to be an effective and affordable treatment option for horses with endotoxaemia. The use of specific cyclooxygenase inhibitors in veterinary medicine have been studied recently. Selective cyclooxygenase-2 inhibitors may

We report on the first patient that suffered an acute thrombosis of the abdominal aorta and survived. Prompt recognition of this complication provides the only hope of survival from this rare and catastrophic complication.

    BACKGROUND: Hemoperitoneum is associated with several emergency conditions and is especially evident when it occurs in patients with liver cirrhosis. This study aimed to assess the clinical characteristics of cirrhotic patients who did not have abdominal trauma or tumor but who developed hemoperitoneum. METHODS: Wereviewedtheclinicalrecordsof1276consecutive cirrhotic patients with hemoperitoneum at our center between January 2007 and December 2009. Hemoperitoneum was confirmed by abdominal paracentesis. RESULTS: Of the 1276 cirrhotic patients, 19 were found to have hemoperitoneum, but only 6 did not have abdominal trauma or tumor. The occurrence of spontaneous hemoperitoneum in the cirrhotic patients was therefore 0.5%. Hemoperitoneum can occur spontaneously in severely decompensated cirrhotic patients with intra-abdominal collateral vessels and high scores on the model for end-stage liver disease and Child-Pugh-Turcotte test. Most patients presented with abdominal distension, abdominal pain, increased abdominal girth and hemodynamic instability with a significant drop in the hemoglobin level. Three patients died of hemorrhagic shock within 24 hours, and the other 3 died of hepatic encephalopathy or spontaneous bacterial peritonitis after 5 to 10 days because of further decompensation of the liver. CONCLUSIONS: Hemoperitoneum can occur in cirrhotic patients who do not have abdominal trauma or tumor. It mainly occurs in severely decompensated end-stage cirrhotic patients. Cirrhotic patients with hemoperitoneum have a poor prognosis.

  11. An unusual cause of abdominal pain.

    LENUS (Irish Health Repository)

    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.

    Retroperitoneal abscesses are unusual occurrences with occult and insidious presentations. There is often a lack of abdominal signs, leading to delays in drainage and high mortality rates. We report a case of thigh emphysema in an 88-year-old patient with diabetes. Prior to admission the patient reported a vague 4-week history of left thigh pain and an inability to fully weight bear. She presented to our emergency department with sepsis and acute kidney impairment. An X-ray of her left femur revealed widespread gas between muscular planes. A retroperitoneal abscess involving the left renal fossa, psoas, iliacus and upper thigh muscles was revealed on an urgent CT scan. The patient was transferred to intensive care unit (ICU) and underwent an emergency drainage. Despite ICU the patient died 2 days after admission.

    Despite progress in surgical techniques and modern medical treatment, postoperative complications occur not infrequently and vary according to type of surgery, clinical setting, and time elapsed since surgery. In general, they can be divided into early and delayed complications. Delayed postoperative complications can be classified as specific and nonspecific. The common nonspecific delayed complications are incisional hernia and postoperative bowel obstruction. Bowel obstruction can be further categorized as obstruction related to benign or neoplastic etiology, the latter occurring in oncology patients in whom the primary surgery was related to an underlying abdominal neoplasm. Gossypiboma is another, fortunately rare, postoperative complication. Specific complications appear after specific operations and include the following: Splenosis - following splenectomy. Retained gallstones and spilled gallstones - following cholecystectomy, mainly laparoscopic. Dropped appendicolith and stump appendicitis - following appendectomy, mainly laparoscopic. Obturation obstruction by a bezoar - following gastric surgery. Afferent loop syndrome (ALS) - following Bilroth II gastrectomy. (author)

    During a 10-year period in which 735 patients presented with abdominal aortic aneurysms to our clinic, 63 were not offered operative treatment. The primary reason for choosing conservative treatment was concomitant diseases that increased the risk of operation. After 2 years of followup, half...... of the patients died, and the cumulative 5-year survival rate was 15%. Aneurysm rupture was the primary cause of death. The cumulative 5-year mortality hazard rate from rupture was 0.36, corresponding to an annual risk of rupture of 7%. The cumulative 5-year hazard rate of death from all other causes was 1.......53, corresponding to an annual risk of 30%. Diameter of the aneurysm was found to be the only factor with a significant impact on the rate of rupture. The cumulative 5-year hazard rate of rupture among patients with aneurysms or = 6 cm was 0.2 and 0.6, respectively, corresponding to an annual risk...

    Abdominal vascular syndromes are rare diseases. Although such syndromes vary widely in terms of symptoms and etiologies, certain imaging findings are characteristic. Depending on their etiology, they can be categorized as congenital-including blue rubber bleb nevus syndrome, Klippel-Trenaunay syndrome, and hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome)-or compressive-including "nutcracker" syndrome, median arcuate ligament syndrome, Cockett syndrome (also known as May-Thurner syndrome), and superior mesenteric artery syndrome. In this article, we aimed to illustrate imaging findings that are characteristic of these syndromes, through studies conducted at our institution, as well as to perform a brief review of the literature on this topic.

    2016-08-01

    We combine electron energy-loss spectroscopy (EELS) and density functional theory (DFT) calculations to study the dispersion and effective mass of excitons in the bulk of WSe2. Our EELS data suggest substantial deviations from the generic quadratic momentum dependence along the Γ K direction. From the DFT-derived Kohn-Sham states we deduce the EELS response without the inclusion of particle-hole attraction to study the possible role of the single-particle band structure on the exciton behavior. Based on this analysis we argue in favor of a strongly momentum dependent particle-hole interaction in WSe2 and other group-VI-transition-metal dichalcogenides.

  18. Warped Graviton Couplings to Bulk Vectors with Brane Kinetic Terms

    CERN Document Server

    Kobakhidze, Archil; Wu, Lei; Yue, Jason

    2016-01-01

    We consider non-universal couplings between Kaluza-Klein (KK) gravitons and bulk Standard Model (SM) vectors in the Randall-Sundrum (RS) model due to the inclusion of both UV and IR brane-localised gauge kinetic terms. We find that such kinetic terms can enhance the couplings of KK gravitons to SM gauge bosons and help ensure the KK vector masses are consistent with electroweak precision constraints. As an application, we consider the 750 GeV diphoton excess observed in the early LHC Run 2 data, identifying the lightest KK graviton with the diphoton resonance and employing brane kinetic terms to increase the coupling to SM vectors.

  19. Limits on hadron spectrum from bulk medium properties

    2016-01-01

    We bring up the fact that the bulk thermal properties of the hadron gas, as measured on the lattice, preclude a very fast rising of the number of resonance states in the QCD spectrum, as assumed by the Hagedorn hypothesis, unless a substantial repulsion between hadronic resonances is present. If the Hagedorn growth continued above masses ~1.8 GeV, then the thermodynamic functions would noticeably depart from the measured lattice values at temperatures above 140 MeV, just below the transition temperature to quark-gluon plasma.

  20. Standardized anatomic space for abdominal fat quantification

    2014-03-01

    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.

  1. Gastroesophageal reflux in children with recurrent abdominal pain.

    van der Meer, S B; Forget, P P; Kuijten, R H; Arends, J W

    1992-02-01

    In this study we investigated the presence of gastroesophageal reflux in children with recurrent abdominal pain and its possible relationship to food intolerance-associated duodenal inflammation. Twenty-four-hour intra-esophageal pH monitoring, an endoscopic duodenal biopsy and a small bowel 51Cr-EDTA permeability test were performed in 25 children with recurrent abdominal pain. In 14 cases (56%) the pH monitoring was abnormal, pointing to the presence of pathological gastroesophageal reflux. Treatment of gastroesophageal reflux in the latter patients resulted in resolution or improvement of abdominal pain in 10 cases (71%). Gastroesophageal reflux did not appear to be associated with either intestinal permeability to 51Cr-EDTA or duodenal biopsy findings. We conclude that pathological gastroesophageal reflex is a frequent finding in children with recurrent abdominal pain, that it is unrelated to duodenal inflammation and that there might be a causal relationship between pathological gastroesophageal reflux and recurrent abdominal pain in children.

    Abdominal ectopic pregnancy is an extremely rare entity, which represents 1% of all ectopic pregnancies and is associated with high maternal and fetal morbidity and mortality. The maternal mortality risk of an abdominal ectopic pregnancy is seven to eight times greater than the risk of a tubal ectopic pregnancy and is 90 times greater than the risk of intrauterine pregnancy. This is a disease of difficult diagnosis that often takes place late. We report the case of a patient with an abdominal ectopic pregnancy, which was diagnosed by abdominal ultrasound in the second trimester; the patient was suc- cessfully treated with exploratory laparotomy with complete removal of the fetus and placenta. We provide a review of the literature on the risk factors for abdominal ectopic pregnancy, diagnostic tests and therapeutic options.

    Objective: Uterus-to-abdominal-wall fistula is a very rare complication after uterine-incision delivery over the last decades. It can even lead to death. Mainly, the fistula occurs when big tension and critical infection exist within the incision of uterus and abdominal wall. Methods: The authors described the clinical presentation, pathology of uterus-to-abdominal-wall fistula, and reported their experience in 6 cases who underwent Z-plasty operation for this rare complication from January 1998 to January 2008. Results: All flaps survived completely and all the wounds in abdominal walls healed very well. The six cases were followed up for 1 to 5 years, and no fistula recurrence occurred. Conclusion: Z-plasty technique is a very simple and efficient approach to repair uterus to abdominal fistula after uterine-incision delivery.

  4. A New Etiology for the Abdominal Compartment Syndrome: Pseudomyxoma Peritonei

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available Pseudomyxoma peritonei (PMP is a rare diagnosis with an incidence of 1-2 per million. Most cases originate from an appendix which ruptures and releases mucin into the peritoneal cavity. The progression of the disease results in obstruction and cutaneous leak. Abdominal compartment syndrome is an uncommon complication of peritoneal pseudomyxoma. In the present article, we report the case of a patient with PMP and abdominal compartment syndrome. A laparotomy to decrease the abdominal pressure was performed. Three months later, a peritonectomy with hyperthermic intraperitoneal chemotherapy was performed. The patient was still alive 1 year after the procedure without any recurrence. In conclusion, acute abdominal pain and respiratory failure in patients with peritoneal PMP should lead to the measurement of the abdominal pressure but are not a contra indication for curative treatment of PMP.

    Full Text Available A 48 year old male admitted to the intensive care unit after a cardiac arrest complicated by a stroke intra-operatively during automatic implantable cardioverter defibrillator placement. He post-operatively developed a rigid abdomen, elevated peak and plateau pressures, hypoxia and renal insufficiency. He was diagnosed with abdominal compartment syndrome with an intra-abdominal compartment pressure of 40mmHg. The patient was administered 10 mg of intravenous cisatracuriumbesylate in preparation for bedside surgical abdominal decompression. Cisatracurium eliminated the patients need for surgical intervention by reducing his abdominal compartment pressures to normal and improving his hypoxia and renal function. This case illustrates that neuromuscular blockade should be attempted in patients with abdominal compartment syndrome prior to surgical intervention.

    Full Text Available 【Abstract】 Objectives: Trauma is among the lead- ing causes of death. Medical management of blunt abdomi- nal trauma (BAT relies on judging patients for whom lap- arotomy is mandatory. This study aimed to determine BAT patients’ signs, as well as paraclinical data, and to clarify the accuracy, sensitivity, specificity, positive and negative predictive value of clinical abdominal scoring system (CASS, a new scoring system based on clinical signs, in predicting whether a BAT patient needs laparotomy or not. Methods: Totally 400 patients suspected of BAT that arrived at the emergency department of two university hos- pitals in Tehran from March 20, 2007 to March 19, 2009 were included in this study. They were evaluated for age, sex, type of trauma, systolic blood pressure, Glasgow coma scale (GCS, pulse rate, time of presentation after trauma, abdomi- nal clinical findings, respiratory rate, temperature, hemoglo- bin (Hb concentration, focused abdominal sonography in trauma (FAST and CASS. Results: Our measurements showed that CASS had an accuracy of 94%, sensitivity of 100%, specificity of 88%, positive predictive value of 90% and negative predictive value of 100% in determining the necessity of laparotomy in BAT patients. Moreover, in our analysis, systolic blood pressure, GCS, pulse rate, Hb concentration, time of presen- tation after trauma, abdominal clinical findings and FAST were also shown to be helpful in confirming the need for laparotomy (P<0.05. Conclusion: CASS is a promising scoring system in rapid detection of the need for laparotomy as well as in minimizing auxiliary expense for further evaluation in BAT patients, thus to promote the cost-benefit ratio and accu- racy of diagnosis.

    2015-02-01

    Full Text Available OBJECTIVE: to present our experience with scheduled reoperations in 15 patients with intra-abdominal sepsis. METHODS: we have applied a more effective technique consisting of temporary abdominal closure with a nylon mesh sheet containing a zipper. We performed reoperations in the operating room under general anesthesia at an average interval of 84 hours. The revision consisted of debridement of necrotic material and vigorous lavage of the involved peritoneal area. The mean age of patients was 38.7 years (range, 15 to 72 years; 11 patients were male, and four were female. RESULTS: forty percent of infections were due to necrotizing pancreatitis. Sixty percent were due to perforation of the intestinal viscus secondary to inflammation, vascular occlusion or trauma. We performed a total of 48 reoperations, an average of 3.2 surgeries per patient. The mesh-zipper device was left in place for an average of 13 days. An intestinal ostomy was present adjacent to the zipper in four patients and did not present a problem for patient management. Mortality was 26.6%. No fistulas resulted from this technique. When intra-abdominal disease was under control, the mesh-zipper device was removed, and the fascia was closed in all patients. In three patients, the wound was closed primarily, and in 12 it was allowed to close by secondary intent. Two patients developed hernia; one was incisional and one was in the drain incision. CONCLUSION: the planned reoperation for manual lavage and debridement of the abdomen through a nylon mesh-zipper combination was rapid, simple, and well-tolerated. It permitted effective management of severe septic peritonitis, easy wound care and primary closure of the abdominal wall.

    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.

    Conclusion: Ultrasonography is considered the best modality in initial evaluation of blunt abdominal trauma patients as it is noninvasive, readily available, and requires minimal preparation time. Ultrasonography is very useful in follow up of patients with intra-abdominal injury and decreases use of CT which has the disadvantages of being expensive, high dose radiation.

    2006-01-01

    We consider the evolution of a bulk scalar field in anti-de Sitter (AdS) spacetime linearly coupled to a scalar field on a de Sitter boundary brane. We present results of a spectral analysis of the system, and find that the model can exhibit both bound and continuum resonant modes. We find that zero, one, or two bound states may exist, depending upon the masses of the brane and bulk fields relative to the Hubble length and the AdS curvature scale and the coupling strength. In all cases, we find a critical coupling above which there exists a tachyonic bound state. We show how the 5-dimensional spectral results can be interpreted in terms of a 4-dimensional effective theory for the bound states. We find excellent agreement between our analytic results and the results of a new numerical code developed to model the evolution of bulk fields coupled to degrees of freedom on a moving brane. This code can be used to model the behaviour of braneworld cosmological perturbations in scenarios for which no analytic result...

    2000-06-01

    The major applications of high-temperature superconductors have mostly been confined to products in the form of wires and thin films. However, recent developments show that rare-earth REBa 2Cu 3O 7- x and light rare-earth LREBa 2Cu 3O 7- x superconductors prepared by melt processes have a high critical-current density at 77 K and high magnetic fields. These superconductors will promote the application of bulk high-temperature superconductors in high magnetic fields; the superconducting bulk magnet for the Maglev train is one possible application. We investigated the possibility of using bulk magnets in the Maglev system, and examined flux-trapping characteristics of multi-superconducting bulks arranged in array.

  13. Changes in lateral abdominal muscles' thickness immediately after the abdominal drawing-in maneuver and maximum expiration.

    Ishida, Hiroshi; Watanabe, Susumu

    2013-04-01

    All lateral abdominal muscles contract more strongly during maximum expiration than during the abdominal drawing-in maneuver (ADIM). However, little is known about which of the lateral abdominal muscles is activated during maximum expiration. Thus, the purpose of this study is to quantify changes in the thickness of the lateral abdominal muscles immediately after the ADIM and maximum expiration. The thickness of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles was measured by ultrasound imaging in 30 healthy men before and after the ADIM and maximum expiration. After the ADIM, there was no significant change in the thickness of the lateral abdominal muscles. After maximum expiration, the thickness of the TrA muscle significantly increased, and there was no significant change in the thickness of the IO and EO muscles. Thus, maximum expiration may be an effective method for TrA, rather than IO and EO, muscle training.

    We follow a formalism presented by Kaiser to calculate the variance of bulk flows in large scale surveys. We apply the formalism to a mock survey of Abell clusters \\'a la Lauer \\& Postman and find the variance in the expected bulk velocities in a universe with CDM, MDM and IRAS--QDOT power spectra. We calculate the velocity variance as a function of the 1--D velocity dispersion of the clusters and the size of the survey.

    Abdominal exercises are often performed on roller or rocker mechanisms, which have been aggressively promoted through the television and print media. However, justifications are lacking as to why these devices are superior to traditional abdominal exercises such as crunches. This study sought to describe and compare the range of motion (ROM) of several joints during crunches performed on 4 different abdominal conditioning devices (2 roller and 2 pivot types) and a traditional crunch exercise. Ten men (29 +/- 5.87 years, 177.5 +/- 6.46 cm, 80.96 +/- 11.72 kg) and 10 women (33.4 +/- 10.16 years, 162.23 +/- 3.83 cm, 56.99 +/- 7.36 kg) subjects agreed to participate in the study. Subjects were videotaped in the sagittal plane (60 Hz) using standard kinematic methods. Reflective markers were placed on the right temple, auditory meatus, shoulder, hip, knee, ankle, heel, toe, and 2 sternum markers placed on a foam piece strapped to the subject's chest. The videotaped movements were automatically digitized (PEAK5 2-D) and the data smoothed using a Butterworth filter. Relative angular ROMs of the head (temple, auditory meatus, shoulder); neck (auditory meatus, shoulder, hip); trunk (near sternum, shoulder, hip); hip (shoulder, hip, knee); sternum/head (sternum near and sternum far with temple and auditory meatus); sternum/trunk (sternum near and sternum far with shoulder and hip); and a sum of 4 angles (head, neck, trunk, hip) were calculated. Sex by equipment repeated measures analyses of variance (ANOVAs) were calculated on the angles of the 5 exercises. When no main effect for sex was found, the data were collapsed across sex and a one-way ANOVA with repeated measures was calculated on the resulting data. Post hoc analyses of pairwise differences were calculated using Tukey's honestly significant difference statistic. Results showed that crunches performed with the abdominal devices resulted in less ROM in all angles measured when compared with a traditional crunch. The

  16. Prospects for Detecting a Cosmic Bulk Flow

    The ΛCDM model is based upon a homogeneous, isotropic space-time leading to uniform expansion with random peculiar velocities caused by local gravitation perturbations. The Cosmic Microwave Background (CMB) radiation evidences a significant dipole moment in the frame of the Local Group. This motion is usually explained with the Local Group's motion relative to the background Hubble expansion. An alternative explanation, however, is that the dipole moment is the result of horizon-scale curvature remaining from the birth of space-time, possibly a result of quantum entanglement with another universe. This would appear as a single velocity (a bulk flow) added to all points in space. These two explanations differ observationally on cosmic distance scales (z > 0.1). There have been many differing attempts to detect a bulk flow, many with no detectable bulk flow but some with a bulk flow velocity as large as 1000 km/s. Here we report on a technique based upon minimizing the scatter around the expected cosine distribution of the Hubble redshift residuals with respect to angular distance on the sky. That is, the algorithm searches for a directional dependence of Hubble residuals. We find results consistent with most other bulk flow detections at z Type Ia Supernovae to be ~0.01, whereas the current error (~0.2.) is more than an order of magnitude too large for the detection of bulk flow beyond z~0.05.

    An 83-year-old woman presented to the emergency department (ED) via emergency medical services with the chief complaint of "strokelike symptoms." Physical examination revealed altered mental status, tachycardia, hypotension, and a large nonpulsatile periumbilical mass. Bedside ultrasound revealed a 9-cm abdominal aortic aneurysm with absent central flow. Computed tomography scan demonstrated diffuse thoracic and abdominal aortic dilation with rupture into the mediastinum along with left hemothorax. Repeat beside ultrasound demonstrated abdominal aortic aneurysm rupture not seen on the computed tomography scan. Despite aggressive resuscitation, the patient developed bradycardia, which devolved into pulseless electric activity cardiac arrest. She was unable to be resuscitated. The patient's diffuse aneurysmal dilation places her into the small category of patients with a disease entity known as mega aorta syndrome (MAS). Mega aorta syndrome is defined as aneurysmal dilation of the aorta to greater than 6 cm in diameter. Although not in our case, most cases of MAS are symptomatic before catastrophic presentation. The disease progression for these patients is slow and occurs over years. When this disease is recognized early, a surgery known as the elephant trunk procedure can be performed. This operation replaces the entire aorta in multiple stages. This gives the emergency physician a critical role in the diagnosis and outcome of these patients because they may come through the ED for an unrelated complaint early in the disease process. This case report illustrates an advanced case of MAS.

    INTRODUCTION: The treatment strategy for appendiceal mass is controversial, ranging from operation or image-guided drainage to conservative treatment with or without antibiotics. The aim of this study was to assess the various treatment modalities with respect to complications and treatment failure......-abdominal abscesses and abscesses of any cause other than appendicitis were excluded as were also studies only describing recurrent appendicitis and/or interval appendectomy. Sub-analyses were performed in children, adults, and in mixed populations. RESULTS: A total of 48 studies were found eligible; they included...... with a treatment failure rate of 8-15%. Drainage was beset with a risk of complications of 2-15% and a risk of treatment failure of 2-13%. CONCLUSION: Operation with appendectomy for appendiceal mass carries a high risk of complications compared with conservative treatment or drainage. Drainage may lower the risk...

  1. Bulk gauge fields in warped space and localized supersymmetry breaking

    Energy Technology Data Exchange (ETDEWEB)

    2003-11-01

    We consider five dimensional supersymmetric warped scenarios in which the Standard Model quark and lepton fields are localized on the ultraviolet brane, while the Standard Model gauge fields propagate in the bulk. Supersymmetry is assumed to be broken on the infrared brane. The relative sizes of supersymmetry breaking effects are found to depend on the hierarchy between the infrared scale and the weak scale. If the infrared scale is much larger than the weak scale the leading supersymmetry breaking effect on the visible brane is given by gaugino mediation. The gaugino masses at the weak scale are proportional to the square of the corresponding gauge coupling, while the dominant contribution to the scalar masses arises from logarithmically enhanced radiative effects involving the gaugino mass that are cutoff at the infrared scale. While the LSP is the gravitino, the NLSP which is the stau is stable on collider time scales. If however the infrared scale is close to the weak scale then the effects of hard supersymmetry breaking operators on the scalar masses can become comparable to those from gaugino mediation. These operators alter the relative strengths of the couplings of gauge bosons and gauginos to matter, and give loop contributions to the scalar masses that are also cutoff at the infrared scale. The gaugino masses, while exhibiting a more complicated dependence on the corresponding gauge coupling, remain hierarchical and become proportional to the corresponding gauge coupling in the limit of strong supersymmetry breaking. The scalar masses are finite and a loop factor smaller than the gaugino masses. The LSP remains the gravitino.

    The diffusion behaviours of hydrogen (H),deuterium (D),and tritium (T) from W(110) surface into bulk and in bulk W are investigated using first-principles calculations combined with simplified models.The diffusion energy barrier is shown to be 1.87 eV from W(110) surface to the subsurface,along with a much reduced harrier of 0.06 eV for the reverse diffusion process.After H enters into the bulk,its diffusion energy barrier with quantum correction is 0.19 eV.In terms of the diffusion theory presented by Wert and Zeuer,the diffusion pre-exponential factor of H is calculated to be 1.57×10-7 m2·s-1,and it is quantitatively in agreement with thc experimental value of 4.1×10-7 m2·s-1.Subsequently,according to mass dependence (√1/m) of H isotope effect,the diffusion pre-exponential factors of D and T are estimated to be 1.11x10-7 m2.s-1 and 0.91×10-7 m2.s-1,respectively.

    2013-08-01

    We performed a comparative study between abdominal and vaginal hysterectomies using clinical data from Al-Jamhouria hospital (one of the largest maternity hospitals in Eastern Libya). Various parameters were taken into consideration: the rates of each type (and their subtypes); average age of patients; indications; causes; postoperative complications; and duration of stay in the hospital afterwards. Conclusions and recommendations were drawn from the results of this study. In light of the aforementioned parameters, it was found that: (1) abdominal hysterectomies were more common than vaginal hysterectomies (p < 0.001); (2) patients admitted for abdominal hysterectomies are younger than those admitted for vaginal hysterectomies (p < 0.001); (3) the most common indication for an abdominal hysterectomy was menstrual disturbances, while for vaginal hysterectomies it was vaginal prolapse; (4) the histopathological cause for abdominal and vaginal hysterectomies were observed and the most common were found to be leiomyomas and atrophic endometrium; (5) there was no significant difference between the two routes in terms of postoperative complications; (6) patients who were admitted for abdominal hysterectomies spent a longer amount of time in the hospital (p < 0.01). It was concluded that efforts should be made to further pursue vaginal and laparoscopic hysterectomies as a viable option to the more conventional abdominal route.

  4. Abdominal circumference contributes to absence of wasting in Brazilian children.

    A number of population groups in Latin America show high prevalences of stunting (low height-for-age) despite very low rates of wasting (weight-for-height deficits). One possible explanation for this phenomenon is an increase in abdominal circumference, which would affect children's weights but not their heights. This study was designed to describe the abdominal circumferences of a group of poor children from Northeast Brazil, and to relate these to their weight-for-weight z-score. Children (n = 252) participating in a government growth monitoring program were studied. The prevalence of stunting (below -2 SD) was 26.2%, but only 1.2% were wasted. Abdominal circumferences increased with age up to 36 mo, followed by a slight decline after 48 mo. Abdominal circumference was the anthropometric measurement most closely associated with weight-for-height, with a coefficient of determination of 41%. Even after adjusting for arm circumference, abdominal circumference continued to explain 16% of the variation in weight-for-height. Despite slight differences in measurement techniques, the study children had consistently larger abdominal girths than a sample of North American children. These findings must be verified by replication but highlight a possible contribution of abdominal circumference in the determination of levels of wasting.

    As many as 50% of end-stage cancer patients will develop ascites and associated symptoms, including pain, tiredness, nausea, depression, anxiety, drowsiness, loss of appetite, dyspnea, perceived abdominal bloating, and immobility. Abdominal massage may stimulate lymph return to the venous system and reduce ascites-related symptoms. The purpose of this study was to test the effect of abdominal massage in reducing these symptoms and reducing ascites itself as reflected in body weight. For a randomized controlled design using repeated measures, a sample of 80 patients with malignant ascites was recruited from gastroenterology and oncology units of a medical center in northern Taiwan and randomly assigned to the intervention or the control group. A 15-minute gentle abdominal massage, using straight rubbing, point rubbing, and kneading, was administered twice daily for 3 days. The control group received a twice-daily 15-minute social interaction contact with the same nurse. Symptoms and body weight were measured in the morning for 4 consecutive days from pre- to post-test. In generalized estimation equation modeling, a significant group-by-time interaction on depression, anxiety, poor wellbeing, and perceived abdominal bloating, indicated that abdominal massage improved these four symptoms, with the greatest effect on perceived bloating. The intervention had no effect on pain, tiredness, nausea, drowsiness, poor appetite, shortness of breath, mobility limitation, or body weight. Abdominal massage appears useful for managing selected symptoms of malignant ascites.

  6. Abdominal expiratory muscle activity in anesthetized vagotomized neonatal rats.

    The pattern of respiratory activity in abdominal muscles was studied in anesthetized, spontaneously breathing, vagotomized neonatal rats at postnatal days 0-3. Anesthesia (2.0% isoflurane, 50% O(2)) depressed breathing and resulted in hypercapnia. Under this condition, abdominal muscles showed discharge late in the expiratory phase (E2 activity) in most rats. As the depth of anesthesia decreased, the amplitude of discharges in the diaphragm and abdominal muscles increased. A small additional burst frequently occurred in abdominal muscles just after the termination of diaphragmatic inspiratory activity (E1 or postinspiratory activity). Since this E1 activity is not often observed in adult rats, the abdominal respiratory pattern likely changes during postnatal development. Anoxia-induced gasping after periodic expiratory activity without inspiratory activity, and in most rats, abdominal expiratory activity disappeared before terminal apnea. These results suggest that a biphasic abdominal motor pattern (a combination of E2 and E1 activity) is a characteristic of vagotomized neonatal rats during normal respiration.

    We aimed to describe anthropometric differences in weight-related disorders between adults with Down syndrome (DS) and healthy controls, as well as their disparate impact on glucose and lipid metabolism disorders. We underwent a cross-sectional study of 49 consecutively selected, community-residing adults with DS and 49 healthy controls in an outpatient clinic of a tertiary care hospital in Madrid, Spain. Siblings of adults with DS were studied as controls in 42 cases. Epidemiological data (age and gender), anthropometric data (body mass index, waist circumference, and waist-to-height ratio [WHR]), coexisting clinical conditions, and laboratory data (fasting glucose, insulin, glycated hemoglobin, creatinine, thyroid hormones, and lipid profile) were measured and compared between the groups. Adults with DS were significantly younger and more often male, with a higher prevalence of overweight and obesity than controls. Adults with DS also had a higher WHR, and more frequently presented abdominal obesity. Moreover, insulin resistance measured using the homeostatic model assessment was more prevalent among adults with DS and abdominal obesity. However, lipid profiles were similar between groups. The kappa correlation index for the diagnosis of abdominal obesity between waist circumference and WHR was 0.24 (95%CI: 0.13-0.34). We concluded that the prevalence of overweight, obesity, and abdominal obesity was higher in adults with DS than in controls. Adults with DS and abdominal obesity showed higher indexes of insulin resistance than their non-obese peers. WHR was a useful tool for the evaluation of abdominal obesity in this population.

    Individuals with diabetes mellitus are advised to achieve a healthy weight to prevent complications. However, fat mass distribution has hardly been investigated as a risk factor for diabetes complications. The authors studied associations between body mass index, waist circumference, waist/hip ratio, and waist/height ratio and mortality among individuals with diabetes mellitus. Within the European Prospective Investigation into Cancer and Nutrition, a subcohort was defined as 5,435 individuals with a confirmed self-report of diabetes mellitus at baseline in 1992-2000. Participants were aged 57.3 (standard deviation, 6.3) years, 54% were men, the median diabetes duration was 4.6 (interquartile range, 2.0-9.8) years, and 22% of the participants used insulin. Body mass index, as indicator of general obesity, was not associated with higher mortality, whereas all measurements of abdominal obesity showed a positive association. Associations generally were slightly weaker in women. The strongest association was observed for waist/height ratio: In the fifth quintile, the hazard rate ratio was 1.88 (95% confidence interval: 1.33, 2.65) for men and 2.46 (95% confidence interval: 1.46, 4.14) for women. Measurements of abdominal, but not general, adiposity were associated with higher mortality in diabetic individuals. The waist/height ratio showed the strongest association. Respective indicators might be investigated in risk prediction models.

    Full Text Available Background: Abdominal injuries contribute significantly to battlefield trauma morbidity and mortality. This study sought to determine the incidence, demographics, clinical features, spectrum, severity, management, and outcome of abdominal trauma during a civilian conflict. Materials and Methods: A prospective analysis of patients treated for abdominal trauma during the Jos civil crises between December 2010 and May 2012 at the Jos University Teaching Hospital. Results: A total of 109 victims of communal conflicts with abdominal injuries were managed during the study period with 89 (81.7% males and 20 (18.3% females representing about 12.2% of the total 897 combat related injuries. The peak age incidence was between 21 and 40 years (range: 3–71 years. The most frequently injured intra-abdominal organs were the small intestine 69 (63.3%, colon 48 (44%, and liver 41 (37.6%. Forty-four (40.4% patients had extra-abdominal injuries involving the chest in 17 (15.6%, musculoskeletal 12 (11%, and the head in 9 (8.3%. The most prevalent weapon injuries were gunshot 76 (69.7%, explosives 12 (11%, stab injuries 11 (10.1%, and blunt abdominal trauma 10 (9.2%. The injury severity score varied from 8 to 52 (mean: 20.8 with a fatality rate of 11 (10.1% and morbidity rate of 29 (26.6%. Presence of irreversible shock, 3 or more injured intra-abdominal organs, severe head injuries, and delayed presentation were the main factors associated with mortality. Conclusion: Abdominal trauma is major life-threatening injuries during conflicts. Substantial mortality occurred with loss of nearly one in every 10 hospitalized victims despite aggressive emergency room resuscitation. The resources expenditure, propensity for death and expediency of timing reinforce the need for early access to the wounded in a concerted trauma care systems.

    Fatty masses, especially solid lipomas, in the paediatric abdomen are very rare. We present such a case, that of an 11-year-old boy who was admitted with abdominal pain and distension. The pre-operative diagnosis of lipoma was suggested by US and CT. The diagnosis of simple lipoma arising in the leaves of the small bowel mesentery, without immature cells, was verified microscopically after the operation. The tumour was enucleated from the mesenterium leaving the intestine intact. We underline the importance of US and CT as pre-operative diagnostic tools. (orig.)

    Using the Tully-Fisher relation, we derive peculiar velocities for the 2MASS Tully-Fisher Survey and describe the velocity field of the nearby Universe. We use adaptive kernel smoothing to map the velocity field, and compare it to reconstructions based on the redshift space galaxy distributions of the 2MASS Redshift Survey (2MRS) and the IRAS Point Source Catalog Redshift Survey (PSCz). With a standard $\\chi^2$ minimization fit to the models, we find that the PSCz model provides a better fit to the 2MTF velocity field data than does the 2MRS model, and provides a value of $\\beta$ in greater agreement with literature values. However, when we subtract away the monopole deviation in the velocity zeropoint between data and model, the 2MRS model also produces a value of $\\beta$ in agreement with literature values. We also calculate the `residual bulk flow': the component of the bulk flow not accounted for by the models. This is $\\sim 250$ km/s when performing the standard fit, but drops to $\\sim 150$ km/s for both...

    Full Text Available Traumatic abdominal wall hernia (TAWH is rare despite the high prevalence of blunt abdominal trauma. Bullhorn hernia occurs as a result of a direct blow to the abdominal wall by the horn of a bull, which disrupts the muscles and fascia and leads to hernia formation. We report a rare case of bullhorn TAWH in a 70-year-old patient who presented with swelling at the left lumbar region. The patient was managed by immediate surgical intervention. A surgeon must have high index of suspicion for the diagnosis of this condition as missed hernias in this setting pose a high risk of strangulation and gangrene.

It is a benign condition but may mimic other serious causes of acute abdomen such as appendicitis, diverticulitis, and gynecological emergency in severe cases. Knowledge of this condition in the differential diagnosis of abdominal pain can save unnecessary hospital admission, antibiotics, and surgery. In this article, we present the case of a 43-year-old female who presented to our hospital with a 2-day history of right lower quadrant abdominal pain and diarrhea. She was diagnosed with EA with computed tomography of abdomen with contrast and was managed conservatively with good outcome.

    A device that generates negative extra-abdominal pressure (ABDOPRE) for treatment of patients with high intra-abdominal pressure was developed. It includes pressure sensors for transducing intra-abdominal pressure through an intra-vesical catheter and negative pressure in the vacuum bell which is placed over the abdomen. By means of a control system, a pattern for reducing IAP is set, according to a clinical protocol. The external negative pressure is generated using a vacuum pump connected to the bell. The system registers the values of interest for the medical history. The system is being tested over ICU patients, registering a satisfactory IAP reduction.

    We report 2 cases of necrotizing fasciitis of the perineum, perianal area, and male genitalia (Fournier's gangrene) that arose secondary to intra-abdominal infectious processes (ruptured appendicitis and diverticulitis). Management consisted of immediate debridement of necrotic tissue, exploratory laparotomy, and diverting colostomy. The presence of an acute abdominal process was not immediately evident on initial evaluation of either patient. This demonstrates the critical importance of considering intra-abdominal infection in patients with Fournier's gangrene when the more commonly seen urinary tract, perirectal, and traumatic causes are not readily apparent.

    Full Text Available Synovial sarcoma (SS is a malignant mesenchymal neoplasm which commonly occurs in the extremities in close association with tendon sheaths, bursae, joint capsules, and fascial structures. Rarely, SS may be present in unexpected location such as the abdominal wall. Surgical resection with wide margins is the initial standard treatment; however, a multimodal approach including radiotherapy and chemotherapy is often favored. Here, we present a case of SS of the anterior abdominal wall in a 14-year-old patient with a right upper abdominal lump. He underwent wide surgical excision and has received adjuvant chemotherapy. He is doing well on follow-up of six months.

    The purpose of this study was to compare ultrasonic measurements of fetal abdominal circumference to ultrasonic measurements of fetal biparietal diameter, as a means of estimating fetal body weight. Of 58 fetuses who had abdominal circumferences measured, 48 (82%) of the predicted weights were within 15% of the actual birth weights. Forty-four of the same 58 fetuses had satisfactory biparietal diameter measurements, but only 21 (48%) of the predicted weights were within 15% of the actual birthweights. Ultrasonic measurement of abdominal circumference appears to be a more reliable index of fetal body weight than other currently available techniques.
