    Full Text Available Warfarin is an oral anticoagulant, which is commonly used in the treatment and prophylaxis of thromboembolic conditions. Bleeding is the primary adverse effect associated with warfarin. The majority of warfarin-related bleedings are spontaneous minor hemorrhages occurring in the subcutaneous or intramuscular tissues and can be treated by decreasing the dose of oral anticoagulants. However, although rare, it is possible to encounter spontaneous major bleedings with increased risk of mortality. Conservative approach is the preferred initial therapy for hemodynamically stable patients with major intra-abdominal hemorrhages that we define as the intermediate group patients. Nevertheless, surgery is required for hemodynamically unstable patients with acute abdominal pain in cases of ongoing active hemorrhage, generalized peritonitis, obstruction, acute abdomen, intestinal ischemia, and perforation. In this article, we present a rare case of acute abdomen and spontaneous intra-abdominal hemorrhage resulting from uncontrolled use of warfarin and a new classification requirement.

    Full Text Available Experimental studies suggest that intra-abdominal infection (IAI induces biological alterations that may affect the risk of lung infection.To investigate the potential effect of IAI at ICU admission on the subsequent occurrence of ventilator-associated pneumonia (VAP.We used data entered into the French prospective multicenter Outcomerea database in 1997-2011. Consecutive patients who had severe sepsis and/or septic shock at ICU admission and required mechanical ventilation for more than 3 days were included. Patients with acute pancreatitis were not included.Of 2623 database patients meeting the inclusion criteria, 290 (11.1% had IAI and 2333 (88.9% had other infections. The IAI group had fewer patients with VAP (56 [19.3%] vs. 806 [34.5%], P<0.01 and longer time to VAP (5.0 vs.10.5 days; P<0.01. After adjustment on independent risk factors for VAP and previous antimicrobial use, IAI was associated with a decreased risk of VAP (hazard ratio, 0.62; 95% confidence interval, 0.46-0.83; P<0.0017. The pathogens responsible for VAP were not different between the groups with and without IAI (Pseudomonas aeruginosa, 345 [42.8%] and 24 [42.8%]; Enterobacteriaceae, 264 [32.8%] and 19 [34.0%]; and Staphylococcus aureus, 215 [26.7%] and 17 [30.4%], respectively. Crude ICU mortality was not different between the groups with and without IAI (81 [27.9%] and 747 [32.0%], P = 0.16.In our observational study of mechanically ventilated ICU patients with severe sepsis and/or septic shock, VAP occurred less often and later in the group with IAIs compared to the group with infections at other sites.

    Procalcitonin is a quite specific biomarker of infection and in recent years has shown its superiority to others markers of inflammation, such as C-reactive protein, for the diagnosis and monitoring of a variety of infections. For this reason, several researchers have studied the potential role of procalcitonin for diagnosis and management of these infections. Intra-abdominal infections are a heterogeneous group of infections that, sometimes, pose difficult challenges to physicians. The published studies have produced mixed results, leading to controversy on the utility of this marker in intra-abdominal infections. This review summarizes these data and discuss the utility of procalcitonin in several intra abdominal infections, including postoperative infections.

    The authors describe three cases of intraabdominal fibromathosis: two cases with intraperithoneal location and another one with retroperithoneal location. All of them are benign noncapsulated tumours of the fibrous tissue with tendancy to local recurrence. Abdominal fibromathosis may determine any form of acute or chronic digestive manifestations. Only to the accuracy of the histo-pathological examination is due the diagnosis between fibromathosis and fibrosarcoma, reactive fibrosis, mixoma and nodular fasceitis. The surgical excision must not be economical and the association with radiant therapy must also be considered.

  6. Effect of Resveratrol on the Prevention of Intra-Abdominal Adhesion Formation in a Rat Model

    2016-06-01

    Full Text Available Background: Intra-abdominal adhesions are a very common complication following abdominal surgery. Our previous studies have demonstrated that the inhibition of inflammation at the sites of peritoneal injury can prevent the formation of intra-abdominal adhesions. Resveratrol is a natural extract with a broad range of anti-inflammatory effects. Therefore, we propose that resveratrol can reduce the formation of intra-abdominal adhesions after surgery. The aim of this study was to investigate the effect of resveratrol on intra-abdominal adhesion prevention in a rat model with surgery-induced peritoneal adhesions. Materials and Methods: The cecum wall and its opposite parietal peritoneum were abraded following laparotomy to induce intra-abdominal adhesion formation. Varying doses of resveratrol were administered to the animals. On the eighth day after surgery, the adhesion score was assessed using a visual scoring system. Picrosirius red staining and a hydroxyproline assay were used to assess the amount of collagen deposition in the adhesion tissues. The levels of serum interleukin-6 (IL-6, tumor necrosis factor (TNF-α, and transforming growth factor beta-1 (TGF-β1 were determined by an enzyme-linked immunosorbent assay (ELISA. Western blotting was performed to determine the protein expression of TGF-β1, fibrinogen, and α-smooth muscle actin (α-SMA in rat peritoneal adhesion tissue. Real-time RT-PCR was performed to quantify the mRNA expression of TGF-β1, fibrinogen, and α-SMA. Results: Resveratrol significantly reduced intra-abdominal adhesion formation and fibrin deposition in the rat model. Furthermore, resveratrol significantly reduced the serum levels of IL-6, TNF-α, and TGF-β1. The protein and mRNA expression of TGF-β1, fibrinogen, and α-SMA in the rat peritoneum and adhesion tissues were also down-regulated due to resveratrol intervention. Conclusion: Resveratrol can effectively prevent the formation of postoperative intra-abdominal

    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.

    Full Text Available Introduction: Prevalence of abdominal trauma is increasing during recent years. Abdomen is the third most affected part of body by trauma. Early diagnosis can help us select better methods for managing abdominal trauma. Even though newer imaging techniques such as CT scan are available, abdominal trauma is still a complex matter, which every doctor in the emergency department has to deal with. Physical examination for the evaluation of intra abdominal organ damage though impotant, is not enough. Material and Methods: This observational (cross-sectional study was done over a period of 24 months (1999-2001. 135 patients (99male and 36 female with abdominal trauma and no urgent laparotomy indication were included in this study. We calculated the sensitivity, specificity, positive&negative predictive values of DPL test in our cases using SPSS software. Results: Mean age of patients was 28.6 years. All of the patients were evaluated with peritoneal lavage which resulted in 70 positive and 65 negative cases. All of the 70 cases with positive results were further evaluated with laparotomy of which 63 cases have intra peritoneal injuries that needed surgical treatment, while 7 cases didn’t have any intra peritoneal injuries (False positive results. All cases with negative results of peritoneal lavage test were treated conservatively for 3-5 days and during this period of time, 3 cases needed laparotomy and surgical treatment (False negative results. Conclusion : According to the results of this study, sensitivity of peritoneal lavage test in diagnosis of abdominal trauma was 95.5% and specificity was 90%. Negative predictive value of this test was 95.4% and positive predictive value of this test was 90%. Thus, peritoneal lavage test in abdominal trauma is sensitive, specific and has high specificity. It is therefore advisable that after initial evaluation of all penetrating and blunt abdominal traumas, peritoneal lavage test should be performed.

    sequential measurement of intra-abdominal pressure is of paramount importance for an early detection and appropriate therapeutic management of intra-abdominal hypertension and abdominal compartment syndrome. to validate a device and technique developed to measure intra-abdominal pressure (an innovation of the Foley urinary catheter named intra-abdominal pressure catheter). three different sets of measurements where done to test the intra-abdominal pressure catheter device: I. 50 measurements were done with the intra-abdominal pressure catheter device and compared against those measurements done using a manometer graded in cm H(2)O; II. Direct measurement of intra-abdominal pressure in five patients during elective laparoscopy vs the intraabdominal pressure catheter device; and III. Measurement of intra-abdominal pressure by the Kron method (Gold standard) vs intra-abdominal pressure catheter device in three patents with intra-abdominal hypertension/abdominal compartment syndrome. Measurements where compared with Pearson correlation test and Bland Altman statistics. I.Intra-abdominal pressure catheter vs graded manometer: r = 0.99, with a mean pressure difference of 0.27 ± 0.23 mmHg, CI (0.039 to 0.092 mmHg). II. Direct measurement of intra-abdominal pressure during laparoscopy vs intra-abdominal pressure catheter device: r = 0.93, with a mean pressure difference of 0.18 ± 0.84 mmHg, CI (-1.46 to 1.83 mmHg) and III. Measurement of intra-abdominal pressure by the Kron Method vs intra-abdominal pressure catheter device: r = 0.81, with a mean pressure difference of -0.41 ± 0.87, CI (-2.12 mmHg to 1.30 mmHg). the intra-abdominal pressure catheter device is a safe and reliable instrument for measuring intra-abdominal pressure.

    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.

    Patients with Parkinson's disease (PD) lose body weight primarily due to decreased body fat mass. The purpose of this study was to elucidate possible factors related to reduction in the intra-abdominal fat mass of 6-hydroxydopamine (6-OHDA)-treated rats, which are frequently used as an animal model for PD. Sham-operated (NPD: n = 4) and unilaterally 6-OHDA-injected (PD: n = 4) 14-wk-old male Sprague-Dawley rats were fed a relatively high-fat diet for 2 wk, during which food intake and body weight were measured. After the 2-wk feeding period, intra-abdominal fat was dissected out and weighed. Carbohydrate and fat absorption-related gene expressions in the jejunum and serum insulin and glucose concentrations were analyzed. Although final body weights did not differ, total intra-abdominal fat weight, expressed relative to body weight, was significantly lower in the PD group than in the NPD group (P NPD rats (P < 0.05). PD model rats displayed loss of intra-abdominal fat, similar to the progressive loss of fat in PD patients. Our results provide preliminary evidence that reduced lipogenesis due to lower insulin levels, rather than impaired digestion/absorption, might have been involved in this decrease in intra-abdominal fat mass.

    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.

    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.

    Intra-abdominal cryptococcosis was diagnosed in two young dogs. The first, an entire male border collie, was presented with vomiting. An abdominal mass detected during physical examination proved to be cryptococcal mesenteric lymphadenitis on exploratory laparotomy. The second dog, a female neutered giant schnauzer, was presented with neurological signs suggestive of encephalopathy. Intestinal cryptococcal granulomas were detected in an extensive diagnostic investigation which included abdominal ultrasonography. The gastrointestinal tract was considered the most likely portal of entry for cryptococcal organisms in both cases. Both dogs were treated using surgery and multiagent antifungal chemotherapy. The first case succumbed despite therapy, while the second dog was treated successfully as gauged by return to clinical normality and a substantial decline in the cryptococcal antigen titre which continued to fall after cessation of treatment.

    2009-06-01

    The incidence of intra-abdominal hypertension (IAH) in patients with severe acute pancreatitis (SAP) is approximately 60-80%. It is usually an early phenomenon, partly related to the effects of the inflammatory process, causing retroperitoneal edema, fluid collections, ascites, and ileus, and partly iatrogenic, resulting from aggressive fluid resuscitation. It also can manifest at a later stage, often associated with local pancreatic complications. IAH is associated with impaired organ dysfunction, especially of the cardiovascular, respiratory, and renal systems. Using current definitions, the incidence of the clinical manifestation, abdominal compartment syndrome (ACS), has been reported as 27% in the largest study so far. Despite several intervention options, the mortality in patients developing ACS remains high: 50-75%. Prevention with judicious use of crystalloids is important, and nonsurgical interventions, such as nasogastric decompression, short-term use of neuromuscular blockers, removal of fluid by extracorporeal techniques, and percutaneous drainage of ascites should be instituted early. The indications for surgical decompression are still not clearly defined, but undoubtedly some patients benefit from it. It can be achieved with full-thickness laparostomy (midline or transverse subcostal) or through a subcutaneous linea alba fasciotomy. Despite the improvement in physiological variables and significant decrease in IAP, the effects of surgical decompression on organ function and outcome are less clear. Because of the significant morbidity associated with surgical decompression and the management of the ensuing open abdomen, more research is needed to define better the appropriate indications and techniques for surgical intervention.

    and vascular cell adhesion molecule 1) and the adhesion assay, a functional measure of endothelial activation, were elevated at 72 hours and 120 hours in mice that underwent CLP versus sham-operations (all at P <0.05). Using a combination of existing murine models for atherosclerosis and sepsis, we found that CLP, a model of intra-abdominal sepsis, accelerates atheroma development. Accelerated atheroma burden was associated with prolonged systemic, endothelial and intimal inflammation and was not explained by ongoing infection. These findings support observations in humans and demonstrate the feasibility of a long-term follow-up murine model of sepsis.

    Intra-abdominal infections are a common problem for the general surgeon and major sources of morbidity and mortality in the intensive care unit. Some of these patients present with peritonitis that can rapidly progress to septic shock. The basic principles of care include prompt resuscitation, antibiotics, and source control. This article will use a detailed case study to outline the management of a patient with severe intra-abdominal infection from diverticulitis from initial resuscitation to reconstruction. Components of the Surviving Sepsis Campaign as they pertain to surgical patients are discussed and updated, and the concept of damage control general surgery is applied. Copyright © 2012.

    Full Text Available Abstract Purpose Appendicitis is the most common abdominal inflammatory process in children which were sometimes followed by complications including intra-abdominal abscess. This later needs classically a surgical drainage. We evaluated the efficacy of antibiotic treatment and surgical drainage. Methods Hospital records of children treated in our unit for intra-abdominal post appendectomy abscesses over a 6 years period were reviewed retrospectively. Results This study investigates a series of 14 children from 2 to 13 years of age with one or many abscesses after appendectomy, treated between 2002 and 2007. Seven underwent surgery and the others were treated with triple antibiotherapy. The two groups were comparable. For the 7 patients who receive medical treatment alone, it was considered efficient in 6 cases (85% with clinical, biological and radiological recovery of the abscess. There was one failure (14%. The duration of hospitalization from the day of diagnosis of intra-abdominal abscess was approximately 10.28 days (range 7 to 14 days. In the other group, the efficacy of treatment was considered satisfactory in all cases. The duration of hospitalization was about 13 days (range: 9 to 20. Conclusion Compared to surgical drainage, antibiotic management of intra-abdominal abscesses was a no invasive treatment with shorter hospitalization.

    Full Text Available Polymicrobial intra-abdominal infections (IAIs are clinically prevalent and cause significant morbidity and mortality, especially those involving fungi. Our laboratory developed a mouse model of IAI and demonstrated that intraperitoneal inoculation with Candida albicans or other virulent non-albicans Candida (NAC species plus Staphylococcus aureus resulted in 70 to 80% mortality in 48 to 72 h due to robust local and systemic inflammation (sepsis. Surprisingly, inoculation with Candida dubliniensis or Candida glabrata with S. aureus resulted in minimal mortality, and rechallenge of these mice with lethal C. albicans/S. aureus (i.e., coninfection resulted in >90% protection. The purpose of this study was to define requirements for C. dubliniensis/S. aureus-mediated protection and interrogate the mechanism of the protective response. Protection was conferred by C. dubliniensis alone or by killed C. dubliniensis plus live S. aureus. S. aureus alone was not protective, and killed S. aureus compromised C. dubliniensis-induced protection. C. dubliniensis/S. aureus also protected against lethal challenge by NAC plus S. aureus and could protect for a long-term duration (60 days between primary challenge and C. albicans/S. aureus rechallenge. Unexpectedly, mice deficient in T and B cells (Rag-1 knockouts [KO] survived both the initial C. dubliniensis/S. aureus challenge and the C. albicans/S. aureus rechallenge, indicating that adaptive immunity did not play a role. Similarly, mice depleted of macrophages prior to rechallenge were also protected. In contrast, protection was associated with high numbers of Gr-1hi polymorphonuclear leukocytes (PMNLs in peritoneal lavage fluid within 4 h of rechallenge, and in vivo depletion of Gr-1+ cells prior to rechallenge abrogated protection. These results suggest that Candida species can induce protection against a lethal C. albicans/S. aureus IAI that is mediated by PMNLs and postulated to be a unique form of

    Pseudomycetomas are deep cutaneous to subcutaneous lesions caused by Microsporum canis mainly described in Persian cats, with few reports of intra-abdominal location. This report describes the clinical signs and lesions of intra-abdominal pseudomycetomas caused by M. canis in two Persian cats. Two Persian cats with a history of previous laparotomy (ovariohysterectomy and nephrostomy) and fecal impaction were examined. Cat #1 was euthanized and subjected to necropsy, histopathology and mycological evaluation. Cat #2 presented with chronic dermatophytosis, and an intra-abdominal mass, that was subjected to histopathology evaluation. Cat #1 presented at necropsy a white-grayish, firm mass (6cm×3.5cm×2.8cm) in the uterine cervix. Cat #2 presented a firm whitish mass (6.5cm×1.5cm×0.5cm) located close to the left kidney. Histologically, both masses contained multifocal granules with hyphae and spores surrounded by Splendore-Hoeppli reaction, with a pyogranulomatous inflammatory infiltrate and fibrous connective tissue proliferation in the periphery. Hyphae and spores exhibited marked Grocott and periodic acid-Schiff staining. M. canis was identified by fungal isolation in cat #1. Pseudomycetoma should be considered as a differential diagnosis in cats, especially in Persian cats presenting with an intra-abdominal mass. Entrance of the agent into the cavity can occur during laparotomy. Copyright © 2016 Asociación Española de Micología. Publicado por Elsevier España, S.L.U. All rights reserved.

  13. Intra-abdominal adhesions in ultrasound. Part II: The morphology of changes

    Full Text Available Despite their frequent appearance, intra-abdominal adhesions are rarely the subject of clinical studies and academic discussions. For many years the operators have been trying to reduce such unfavourable consequences of interventions in the abdominal structures. The aim of this article is to present the possibilities of intra-abdominal adhesion diagnostics by means of ultrasound imaging based on authors’ own experience and information included in pertinent literature. The anatomy and examination technique of the abdominal wall were discussed in Part I of the article. In order to evaluate intraperitoneal adhesions, one should use a convex transducer with the frequency of 3.5–6 MHz. The article provides numerous examples of US images presenting intra-abdominal adhesions, particularly those which appeared after surgical procedures. The significance of determining their localisation and extensiveness prior to a planned surgical treatment is emphasized. Four types of morphological changes in the ultrasound caused by intra-abdominal adhesions are distinguished and described: visceroperitoneal adhesions, intraperitoneal adhesions, adhesive obstructions as well as adhesions between the liver and abdominal wall with a special form of such changes, i.e. hepatic pseudotumour. Its ultrasound features are as follows: 1. The lesion is localised below the scar in the abdominal wall after their incision. 2. The lesion is localised in the abdominal part of the liver segments III, IV and V. 3. With the US beam focus precisely set, the lack of fascia – peritoneum complex may be noticed. An uneven liver outline or its ventral displacement appears. 4. A hepatic adhesion-related pseudotumour usually has indistinct margins, especially the posterior one, and, gradually, from top to bottom, loses its hypoechogenic nature. 5. In a respiration test, this liver fragment does not present the sliding movement – a neoplastic tumour rarely shows such an effect

  14. The effects of intra-abdominal hypertension on the secretory function of canine adrenal glands.

    Full Text Available Intra-abdominal hypertension (IAH can damage multiple organ systems, but the explicit impact on the adrenal gland is unclear. To evaluate the effects of intra-abdominal pressure (IAP on the secretory function of the adrenal glands, we established canine models of IAH. By comparing morphology; hemodynamics; plasma cortisol, aldosterone, epinephrine, and norepinephrine concentrations; and the expression of IL-1, IL-6, and TNF-α in adrenal gland tissue from these dogs, we found that hemodynamic instability occurred after IAH and that IAH increased the plasma cortisol, aldosterone, epinephrine, and norepinephrine concentrations. Higher IAPs resulted in more significant changes, and the above indicators gradually returned to normal 2 h after decompression. Compared with the sham-operated group, IAH significantly increased IL-1, IL-6, and TNF-α levels in adrenal tissue, with larger increases in the presence of higher IAPs. However, the concentrations of these markers remained higher than those in the sham-operated group despite their decrease after 2 h of decompression. Histopathological examination revealed congestion, red blood cell exudation, and neutrophil infiltration in the adrenal glands when IAP was elevated; these conditions became more significant with more severe IAH. These results suggest that the secretion of adrenal hormones and adrenal gland inflammation are positively correlated with IAP and that abdominal decompression effectively corrects adrenal gland function.

    Serious intra-abdominal injuries are very uncommon in cricket; traumatic cricket injuries are traditionally musculoskeletal, soft tissue or maxillofacial in origin. The cause of such cricket injuries can be broadly divided into collision type injuries (a result of direct contact with the ball or bat, another player, the ground or boundary) or overuse injuries (due to running, throwing, batting, bowling, repetitive movements and overexertion). This case report describes a rare cause of small bowel perforation and suspected genitofemoral nerve injury secondary to the direct impact of a cricket ball, and includes a brief review of blunt abdominal injuries resulting in isolated small bowel perforations. 2015 BMJ Publishing Group Ltd.

  16. A user's guide to intra-abdominal pressure measurement.

    2015-01-01

    The intra-abdominal pressure (IAP) measurement is a key to diagnosing and managing critically ill medical and surgical patients. There are an increasing number of techniques that allow us to measure the IAP at the bedside. This paper reviews these techniques. IAP should be measured at end-expiration, with the patient in the supine position and ensuring that there is no abdominal muscle activity. The intravesicular IAP measurement is convenient and considered the gold standard. The level where the mid-axillary line crosses the iliac crest is the recommended zero reference for the transvesicular IAP measurement; moreover, marking this level on the patient increases reproducibility. Protocols for IAP measurement should be developed for each ICU based on the locally available tools and equipment. IAP measurement techniques are safe, reproducible and accurate and do not increase the risk of urinary tract infection. Continuous IAP measurement may offer benefits in specific situations in the future. In conclusion, the IAP measurement is a reliable and essential adjunct to the management of patients at risk of intra-abdominal hypertension.

    2008-08-01

    Full Text Available We report the clinical experience of one patient with perforated duodenal diverticulitis who was successfully treated by intra-abdominal drainage and feeding jejunostomy. A 53-year-old male patient visited our hospital due to acute onset of abdominal pain and distension. Physical examination revealed tenderness over the epigastric area and right-lower quadrant of the abdomen without obvious rebound tenderness or muscle guarding. Duodenal diverticulitis with a retroperitoneal abscess was identified by abdominal computed tomography scan. Surgical intervention was performed after the failure of conservative treatment. The operative findings were compatible with perforated duodenal diverticulitis, and intra-abdominal drainage of retroperitoneal abscess with simultaneous feeding jejunostomy was undertaken. The patient was doing well at the 4-month postoperative follow-up visit. We suggest the use of a conservative operative method, as opposed to conventional diverticulectomy and duodenorrhaphy, as an alternative approach for the management of this disorder, especially when conservative treatment has failed.

    Full Text Available We report a case of intra-abdominal testicular tumor in a 36-year-old married lady presenting with chief complaints of primary amenorrhea. The patient was later diagnosed with testicular feminization syndrome, a form of male pseudohermaphroditism. This testicular tumor was histologically proven as seminoma. Due to rarity, imaging findings in patients with testicular feminization syndrome and intraabdominal testicular tumor have been poorly documented. So far, only one case report had described the combined role of CT and MR imaging in intraabdominal testicular sex-cord stromal tumor. To our knowledge, this case is first to document USG and MR imaging in addition to MR spectroscopy features in intraabdominal testicular seminoma.

  2. Handlebar hernia: an uncommon cause of intra-abdominal lesions.

    Science.gov (United States)

    Schoofs, N; Van der Speeten, K

    2013-01-01

    A traumatic abdominal wall hernia (TAWH) is an uncommon complication of abdominal trauma. Handlebar hernia is an even rarer type of traumatic abdominal wall hernia, with only 33 previously reported cases in literature. It is caused by a local trauma with a handlebar-like object which is not sharp enough to penetrate the elastic skin, but has sufficient focused force to breach the muscle and fascia of the abdominal wall. A high index of clinical suspicion for associated intra-abdominal lesions in patients with traumatic abdominal wall hernia is warranted. This may not only influence the immediate treatment of the abdominal hernia but also the type and timing of mesh repair to be performed. Early repair is mandatory to avoid complications. The choice for primary repair versus mesh repair will be discussed according to the size of the hernia and the amount of tissue destruction by the trauma. The type of mesh used for the repair will be determined by presence or absence of contamination in the abdomen.

  3. Therapeutic Role of Interleukin 22 in Experimental Intra-abdominal Klebsiella pneumoniae Infection in Mice.

    Interleukin 22 (IL-22) is an IL-10-related cytokine produced by T helper 17 (Th17) cells and other immune cells that signals via IL-22 receptor alpha 1 (IL-22Ra1), which is expressed on epithelial tissues, as well as hepatocytes. IL-22 has been shown to have hepatoprotective effects that are mediated by signal transducer and activator of transcription 3 (STAT3) signaling. However, it is unclear whether IL-22 can directly regulate antimicrobial programs in the liver. To test this hypothesis, hepatocyte-specific IL-22Ra1 knockout (Il22Ra1(Hep-/-)) and Stat3 knockout (Stat3(Hep-/-)) mice were generated and subjected to intra-abdominal infection with Klebsiella pneumoniae, which results in liver injury and necrosis. We found that overexpression of IL-22 or therapeutic administration of recombinant IL-22 (rIL-22), given 2 h postinfection, significantly reduced the bacterial burden in both the liver and spleen. The antimicrobial activity of rIL-22 required hepatic Il22Ra1 and Stat3. Serum from rIL-22-treated mice showed potent bacteriostatic activity against K. pneumoniae, which was dependent on lipocalin 2 (LCN2). However, in vivo, rIL-22-induced antimicrobial activity was only partially reduced in LCN2-deficient mice. We found that rIL-22 also induced serum amyloid A2 (SAA2) and that SAA2 had anti-K. pneumoniae bactericidal activity in vitro. These results demonstrate that IL-22, through IL-22Ra1 and STAT3 singling, can induce intrinsic antimicrobial activity in the liver, which is due in part to LCN2 and SAA2. Therefore, IL-22 may be a useful adjunct in treating hepatic and intra-abdominal infections. Copyright © 2016, American Society for Microbiology. All Rights Reserved.

    Intra-abdominal pressure is the pressure's state of balance within the abdominal cavity when a patient is at rest. This pressure may vary during mechanical ventilation or spontaneous breathing. The objective was to establish the intra-abdominal pressure as a surgery predictor in patients with acute abdominal pain. From April to December, 2013, it was carried out a nested case-control study on patients with acute abdominal pain in the emergency room of a second level hospital. Thirty-seven patients fit the inclusion criteria; they all underwent surgery with a previous measurement of the intra-abdominal pressure. Based on the results of the anatomopathological study, we divided the patients into two groups: those with evidence of acute abdominal inflammatory process (n=28) (case group), and patients without evidence of acute abdominal inflammatory process (n=9) (control group). In the case group, 100 % of patients shown high intra-abdominal pressure with a p=0.01 (OR=5 [95 % CI=2.578-9.699]. In the case group, the mean intra-abdominal pressure was 11.46, and in the control group 9.2 (p=0.183). Abdominal pain requiring surgical intervention is directly related to intra-abdominal pressure>5 mmHg.

    Full Text Available Introduction. Early assessment of the severity and etiology of acute pancreatitis is very important for further treatment procedures. The aim of the study was to investigate the association between intra-abdominal pressure (IAP and procalcitonin as an indicator of severity of acute pancreatitis. Method. The IAP is measured every 12 hours through the urinary catheter placed in the bladder, in 65 patients with acute pancreatitis. Procalcitonin is measured within 24 hours of receipt of the patient, after 48 hours and after 78 hours. These values of procalcitonin and IAP were compared to each other and in relation to the Acute Physiology, Age and Chronic Health Evaluation II (APACHE II scoring system. Patients with APACHE II score > 8 are defined with moderate and severe acute pancreatitis. Results. The values of IAP (18,1 ± 4,5 mmHg vs 8,9 ± 2,67 mmHg; p = 0,01 , procalcitonin (15,43 + 2,25 ng/ml vs 3,14 + 1,12 ng/ml; p =0,031 and APACHE II scoring system (17,3 ± 6,24 vs 6,5 ± 1,0; p = 0,013 were significantly higher in patients with moderate and severe acute pancreatitis. The increase in the value of IAP was accompanied by an increase in the value of procalcitonin (r = 0,581, p = 0,01. The sensitivity in the prediction of severe acute pancreatitis after 24 hours of receiving the patient is 91,7% for the IAP, 87,8% for procalcitonin and 84,9% for APACHE II scoring system. Conclusion. The increase in the value of the IAP is accompanied by an increase in the values of procalcitonin, also patients with higher values of APACHE II scoring sys­tem have higher values of IAP and procalcitonin. The values of IAP and procalcitonin can be used as markers of acute pancreatitis severity.

    It is known that intra-abdominal hypertension has high morbidity in acute pancreatitis and has detrimental effects on patients. For third trimester pregnancy complicated by acute pancreatitis, the intra-abdominal pressure may have its own characteristic. This article will discuss this clinical scenario. This observational study in a cohort group was performed in the surgical intensive care unit of a tertiary hospital. Medical records were reviewed from each acute pancreatitis exactly in third trimester pregnancy. The main statistical methods were Mann-Whitney U test and bivariate Pearson correlation analysis. During the study interval, there were totally 17 pregnancies complicated by acute pancreatitis in the third trimester. All cases with moderate or severe acute pancreatitis had intra-abdominal hypertension of mean value of 16.7 mm Hg (range, 12.9-22.0 mm Hg). The intra-abdominal pressure had significant correlation with APACHE II score (r = 0.7456, p = 0.0006), while a negative correlation was showed with the umbilical artery pH value and with 1-min Apgar score (r = -0.8232, p = 0.0005; r = -0.7465, p = 0.0034; respectively). The intra-abdominal pressure of those with live infants was lower than that of those with dead ones (13.78 ± 2.554 vs. 19.84 ± 1.695, p = 0.0019). The incidence of intra-abdominal hypertension seems higher in moderate or severe acute pancreatitis in third trimester pregnancy than the non-pregnant cases but there's no significance in this study. Acute elevated intra-abdominal pressure accounts for great association with mother's serious scenario and fetal mortality.

    Objective To evaluate the frequency of intra-abdominal hypertension in major burn patients and its association with the occurrence of acute kidney injury. Methods This was a prospective cohort study of a population of burn patients hospitalized in a specialized intensive care unit. A convenience sample was taken of adult patients hospitalized in the period from 1 August 2015 to 31 October 2016. Clinical and burn data were collected, and serial intra-abdominal pressure measurements taken. The significance level used was 5%. Results A total of 46 patients were analyzed. Of these, 38 patients developed intra-abdominal hypertension (82.6%). The median increase in intra-abdominal pressure was 15.0mmHg (interquartile range: 12.0 to 19.0). Thirty-two patients (69.9%) developed acute kidney injury. The median time to development of acute kidney injury was 3 days (interquartile range: 1 - 7). The individual analysis of risk factors for acute kidney injury indicated an association with intra-abdominal hypertension (p = 0.041), use of glycopeptides (p = 0.001), use of vasopressors (p = 0.001) and use of mechanical ventilation (p = 0.006). Acute kidney injury was demonstrated to have an association with increased 30-day mortality (log-rank, p = 0.009). Conclusion Intra-abdominal hypertension occurred in most patients, predominantly in grades I and II. The identified risk factors for the occurrence of acute kidney injury were intra-abdominal hypertension and use of glycopeptides, vasopressors and mechanical ventilation. Acute kidney injury was associated with increased 30-day mortality. PMID:29513889

    Abstract Background: Low serum albumin concentration is a predictor of failure of source control for intra-abdominal infection. However, data on dynamics of albumin synthesis in these patients and to what extent these changes contribute to hypoalbuminemia are relatively scarce. We investigated in a group of patients with gastrointestinal fistula the dynamic response of liver albumin synthesis to intra-abdominal abscess and how these related to hypoalbuminemia and circulating endocrine hormone profiles. Methods: Eight gastrointestinal fistula patients scheduled to undergo percutaneous abscess sump drainage were enrolled prospectively to measure albumin synthesis rates at different stages of the inflammatory response (immediately after diagnosis and 7 d following sump drainage when clinical signs of intra-abdominal sepsis had been eradicated). Eight age-, sex-, and body mass index–matched intestinal fistula patients were studied as control patients. Consecutive arterial blood samples were drawn during a primed-constant infusion (priming dose: 4 micromol·kg−1, infusion rate: 6 micromol·kg−1·min−1) to determine the incorporation rate of L-[ring-2H5]-phenylalanine directly into plasma albumin using gas chromatography/mass spectrometry analysis. Results: Patients suffering from intra-abdominal infection had reduced plasma albumin and total plasma protein concentrations, compared with control patients. Albumin fractional synthesis rates in patients with intra-abdominal abscess were decreased, compared with those in the control group. When the source of infection was removed, albumin synthesis rates returned to control values, whereas albumin concentrations did not differ significantly from the corresponding concentrations in control subjects and patients with intra-abdominal abscess. Conclusion: Despite nutritional intervention, albumin synthesis rate is decreased in intestinal fistula patients with intra-abdominal abscess; albumin synthesis returns to

    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.

    2015-03-01

    Full Text Available Intra-abdominal infections are multifactorial and present an complex inflammatory response of the peritoneum to microorganisms followed by exudation in the abdominal cavity and systemic response Despite advances in management and critical care of patients with acute generalized peritonitis due to hollow viscus perforation, prognosis is still very poor, with high mortality rate. Early detection and adequate treatment is essential to minimize complications in the patient with acute abdomen. Prognostic evaluation of complicated IAI by modern scoring systems is important to assess the severity and the prognosis of the disease. Control of the septic source can be achieved either by nonoperative or operative means. Nonoperative interventional procedures include percutaneous drainages of abscesses. The management of primary peritonitis is non-surgical and antibiotic- treatment. The management of secondary peritonitis include surgery to control the source of infection, removal of toxins, bacteria, and necrotic tissue, antibiotic therapy, supportive therapy and nutrition. "Source control" is sine qua non of success and adequate surgical procedure involves closure or resection of any openings into the gastrointestinal tract, resection of inflamed tissue and drainage of all abdominal and pelivic collections.

Methods  Twelve healthy mini-pigs (Bama, Guangxi were selected for bloodletting from the femoral artery to reproduce hemorrhagic shock model (mean arterial blood pressure, 50mmHg, 1h, and IAH model was successfully reproduced in eight pigs by partial occlusion of portal vein. The eight pigs were randomly divided into the intra-abdominal volume increment treatment (IT group (n=4 and sham operation control (SC group (n=4. Vesical pressure (VP and inferior vena cava pressure (IVCP were observed before shock, 2h after IAH, and 22h after IAVI treatment. Aspartate aminotransferase (AST and alanine aminotransferase (ALT were measured. In addition, the ratio of the abdominal anteroposterior diameter to the transverse diameter was assessed, and the liver CT values were measured after enhanced CT scanning. The pigs were sacrificed 26h after operation. Liver specimens were collected to measure the ratio of wet weight to dry weight and pathological examination. Results  The VP in 8 IAH pigs was 21.16±4.63mmHg. The ratio of abdominal anteroposterior diameter to the transverse diameter increased remarkably 2h after IAH compared with that before shock (1.22±1.41 vs 0.96±0.08, PPvs 42.73±4.92HU, PPPvs 5.14±0.71, PConclusions  The established model could better reproduce the symptoms of IAH after hemorrhagic shock and fluid resuscitation, accompanied by liver damage. IAVI helps to relieve liver functional disturbance after IAH, which is related to decreased intra-abdominal pressure and hypoxia-ischemia of the liver.

    The roles of antagonistic activation of abdominal muscles and of intra-abdominal pressurization remain enigmatic, but are thought to be associated with both spinal unloading and spinal stabilization in activities such as lifting. Biomechanical analyses are needed to understand the function of intra-abdominal pressurization because of the anatomical and physiological complexity, but prior analyses have been over-simplified. To test whether increased intra-abdominal pressure was associated with reduced spinal compression forces for efforts that generated moments about each of the principal axis directions, a previously published biomechanical model of the spine and its musculature was modified by the addition of anatomically realistic three-layers of curved abdominal musculature connected by fascia to the spine. Published values of muscle cross-sectional areas and the active and passive stiffness properties were assigned. The muscle activations were calculated assuming minimized muscle stress and stretch for the model loaded with flexion, extension, lateral bending and axial rotation moments of up to 60 Nm, along with intra-abdominal pressurization of 5 or 10 kPa (37.5 or 75 mm Hg) and partial bodyweight (340 N). The analysis predicted a reduction in spinal compressive force with increase in intra-abdominal pressurization from 5 to 10 kPa. This reduction at 60 Nm external effort was 21% for extension effort, 18% for flexion effort, 29% for lateral bending and 31% for axial rotation. This analysis predicts that intra-abdominal pressure produces spinal unloading, and shows likely muscle activation patterns that achieve this. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Full Text Available OBJECTIVE: The aim of this study was to quantify the interaction between increased intra-abdominal pressure and Positive-End Expiratory Pressure. METHODS: In 30 mechanically ventilated ICU patients with a fixed tidal volume, respiratory system plateau and abdominal pressure were measured at a Positive-End Expiratory Pressure level of zero and 10 cm H2O. The measurements were repeated after placing a 5 kg weight on the patients' belly. RESULTS: After the addition of 5 kg to the patients' belly at zero Positive-End Expiratory Pressure, both intra-abdominal pressure (p<0.001 and plateau pressures (p=0.005 increased significantly. Increasing the Positive-End Expiratory Pressure levels from zero to 10 cm H2O without weight on the belly did not result in any increase in intra-abdominal pressure (p=0.165. However, plateau pressures increased significantly (p< 0.001. Increasing Positive-End Expiratory Pressure from zero to 10 cm H2O and adding 5 kg to the belly increased intra-abdominal pressure from 8.7 to 16.8 (p<0.001 and plateau pressure from 18.26 to 27.2 (p<0.001. Maintaining Positive-End Expiratory Pressure at 10 cm H2O and placing 5 kg on the belly increased intra-abdominal pressure from 12.3 +/- 1.7 to 16.8 +/- 1.7 (p<0.001 but did not increase plateau pressure (26.6+/-1.2 to 27.2 +/-1.1 -p=0.83. CONCLUSIONS: The addition of a 5kg weight onto the abdomen significantly increased both IAP and the airway plateau pressure, confirming that intra-abdominal hypertension elevates the plateau pressure. However, plateau pressure alone cannot be considered a good indicator for the detection of elevated intra-abdominal pressure in patients under mechanical ventilation using PEEP. In these patients, the intra-abdominal pressure must also be measured.

    Full Text Available Gastrointestinal perforation is a serious adverse event that occurs in approximately 1% of patients receiving ramucirumab and paclitaxel. A 67-year-old man with unresectable advanced gastric cancer was admitted to our hospital and treated with ramucirumab and paclitaxel. Gastric perforation occurred during the second cycle of chemotherapy. Although the patient’s condition improved without surgery, an abscess developed in the intra-abdominal fluid collection resulting from the perforation. We performed endoscopic ultrasound-guided abscess drainage. The patient improved and was discharged in satisfactory condition. Endoscopic ultrasound-guided drainage is a treatment option for patients with intra-abdominal abscess following gastric perforation due to ramucirumab.

    Full Text Available Introduction. Postoperative disorders of gastrointestinal tract (GIT motility are often after abdominal operations. Postoperative enteroparesis is usually accompanied by the raise of intra-abdominal pressure (IAP.Materials and methods. After approval of research by bioethics committee and informed consent 52 patients were prospectively divided in 2 groups depending on the type of postoperative intensive care. Patients underwent operations on abdominal cavity by laparotomy incision on the subject of peritonitis. Patient of the 1 (control group (n=27 after operation received stimulation of GIT with metoclopramide and simethicone.  In the 2 group (n=25 patients received metoclopramide and simethicone. Patients were comparable on age, sex, concomitant pathology, ASA class (IIE-IIIE and the type of operative intervention (laparotomy on the subject of peritonitis. IAP level was studied before operation and at 1,2,3 days after it. IAP was measured by indirect method trough the urinary bladder. The values recommended by the World society of abdominal compartment syndrome were considered as the normal IAP level.  Perfuse pressure (PP in abdominal cavity was calculated by formula: PP=MAP-ICP where MAP – mean arterial pressure. There were also studied indices of the central and peripheral hemodynamics, inflammation markers (leukocytes, fibrinogen level, IL-1α, TNFα, IL-10, leukocytic index of intoxication was calculated. The final point of research was 28 day after operation when we evaluated mortality and life quality on Rancho Los Amigos scale.Results and discussion. We registered the raise of IAP in 63.1% of patients. The value of intra-abdominal pressure exceeded an upper limit of the normal one by 58,5% (р <0,001. Among patients with high IAP 83% had intra-abdominal hypertension (IAH of 1 degree, 17% - of 2 degree.  The development of 3 and 4degree IAH were not observed before operation. PP remained within the normal.Correlative analysis

    Severe acute pancreatitis may be complicated by intra-abdominal hypertension (IAH), abdominal compartment syndrome (ACS), and intestinal ischemia. The aim of this retrospective study is to describe the incidence, treatment, and outcome of patients with severe acute pancreatitis and ACS, in particular the occurrence of intestinal ischemia. The medical records of all patients admitted with severe acute pancreatitis admitted to the ICU of a tertiary referral center were reviewed. The criteria proposed by the World Society of the Abdominal Compartment Syndrome (WSACS) were used to determine whether patients had IAH or ACS. Fifty-nine patients with severe acute pancreatitis were identified. Intra-abdominal pressure (IAP) measurements were performed in 29 patients (49.2 %). IAH was present in all patients (29/29). ACS developed in 13/29 (44.8 %) patients. Ten patients with ACS underwent decompressive laparotomy. A large proportion of patients with ACS had intra-abdominal ischemia upon laparotomy: 8/13 (61.5 %). Mortality was high in both the ACS group and the IAH group. This study confirms that ACS is common in severe acute pancreatitis. Intra-abdominal ischemia occurs in a large proportion of patients with ACS. Swift surgical intervention may be indicated when conservative measures fail in patients with ACS. National and international guidelines need to be updated so that routine IAP measurements become standard of care for patients with severe acute pancreatitis in the ICU.

    Full Text Available In accordance with the trans-lamina cribrosa pressure difference theory, decreasing the trans-lamina cribrosa pressure difference can relieve glaucomatous optic neuropathy. Increased intracranial pressure can also reduce optic nerve damage in glaucoma patients, and a safe, effective and noninvasive way to achieve this is by increasing the intra-abdominal pressure. The purpose of this study was to observe the changes in orbital subarachnoid space width and intraocular pressure at elevated intra-abdominal pressure. An inflatable abdominal belt was tied to each of 15 healthy volunteers, aged 22–30 years (12 females and 3 males, at the navel level, without applying pressure to the abdomen, before they laid in the magnetic resonance imaging machine. The baseline orbital subarachnoid space width around the optic nerve was measured by magnetic resonance imaging at 1, 3, 9, and 15 mm behind the globe. The abdominal belt was inflated to increase the pressure to 40 mmHg (1 mmHg = 0.133 kPa, then the orbital subarachnoid space width was measured every 10 minutes for 2 hours. After removal of the pressure, the measurement was repeated 10 and 20 minutes later. In a separate trial, the intraocular pressure was measured for all the subjects at the same time points, before, during and after elevated intra-abdominal pressure.

    Full Text Available ABSTRACT Objective: to identify victims of blunt abdominal trauma in which intra-abdominal injuries can be excluded by clinical criteria and by complete abdominal ultrasonography. Methods: retrospective analysis of victims of blunt trauma in which the following clinical variables were analyzed: hemodynamic stability, normal neurologic exam at admission, normal physical exam of the chest at admission, normal abdomen and pelvis physical exam at admission and absence of distracting lesions (Abbreviated Injury Scale >2 at skull, thorax and/or extremities. The ultrasound results were then studied in the group of patients with all clinical variables evaluated. Results: we studied 5536 victims of blunt trauma. Intra-abdominal lesions with AIS>1 were identified in 144 (2.6%; in patients with hemodynamic stability they were present in 86 (2%; in those with hemodynamic stability and normal neurological exam at admission in 50 (1.8%; in patients with hemodynamic stability and normal neurological and chest physical exam at admission, in 39 (1.5%; in those with hemodynamic stability, normal neurological, chest, abdominal and pelvic physical exam at admission, in 12 (0.5%; in patients with hemodynamic stability, normal neurological, chest, abdominal and pelvic physical exam at admission, and absence of distracting lesions, only two (0.1% had intra-abdominal lesions. Among those with all clinical variables, 693 had normal total abdominal ultrasound, and, within this group, there were no identified intra-abdominal lesions. Conclusion: when all clinical criteria and total abdominal ultrasound are associated, it is possible to identify a group of victims of blunt trauma with low chance of significant intra-abdominal lesions.

    Chronic sepsis is always associated with profound wasting leading to increased release of amino acids from skeletal muscle. Net protein catabolism may be due to decreased rate of synthesis, increased rate of degradation, or both. To determine whether protein synthesis is altered in chronic sepsis, the rate of protein synthesis in vivo was estimated by measuring the incorporation of [ 3 H]-phenylalanine in skeletal muscle protein in a chronic (5-day) septic rat model induced by creation of a stable intra-abdominal abscess using an E. coli + B. fragilis-infected sterile fecal-agar pellet as foreign body nidus. Septic rats failed to gain weight at rates similar to control animals, therefore control animals were weight matched to the septic animals. The skeletal muscle protein content in septic animals was significantly reduced relative to control animals (0.18 +/- 0.01 vs. 0.21 +/- 0.01 mg protein/gm wet wt; p less than 0.02). The rate of incorporation of [ 3 H]-phenylalanine into skeletal muscle protein from control animals was 39 +/- 4 nmole/gm wet wt/hr or a fractional synthetic rate of 5.2 +/- 0.5%/day. In contrast to control animals, the fractional synthetic rate in septic animals (2.6 +/- 0.2%/day) was reduced by 50% compared to control animals (p less than 0.005). The decreased rate of protein synthesis in sepsis was not due to an energy deficit, as high-energy phosphates and ATP/ADP ratio were not altered. This decrease in protein synthesis occurred even though septic animals consumed as much food as control animals

    Surgical-site infections (SSIs) and intra-abdominal abscesses (IAAs) are the most frequent complications of appendectomy. The role of laparoscopy in the treatment of appendicitis remains controversial concerning the complication rate. The aim of this retrospective cohort study was to compare open and laparoscopic appendectomy for SSI and IAA. All patients undergoing appendectomy between January 1, 2007 and May 31, 2010 were included in the study. Perioperative data and data on postoperative complications were collected from patient files. A questionnaire was used to assess complications after discharge. Main outcome parameters were SSI and IAA. Open appendectomy (OAG) and laparoscopic appendectomy (LAG) were compared with univariate and multivariate analyses for the outcome parameters. Four hundred thirty patients were included in the study. SSI (all: 10.6%, OAG: 11.7%, LAG: 7.5%, P=0.293) and IAA (all: 2.8%, OAG: 2.4%, LAG: 3.8%, P=0.506) were not significantly different between OAG and LAG. Risk factors for SSI were age (P=0.003), body mass index (P=0.017), ASA score (P=0.001), the intraoperative grade of inflammation (P=0.004), and the histologic grade of inflammation (P=0.015). The only risk factor for IAA was the intraoperative grade of inflammation (P=0.028). ASA score (odds ratio: 1.992, P=0.032) and the intraoperative grade of inflammation (odds ratio: 1.573, P=0.006) remained significant in the multivariate analysis for SSI. A higher ASA score correlates with SSI. A higher grade of intraoperative inflammation correlates with SSI and IAA. Laparoscopy has no impact on SSI and IAA in appendectomy.

    Intra-abdominal obesity is associated with cardiovascular disease and non-insulin-dependent diabetes mellitus, and physical training has been suggested to alleviate these conditions. We compared epinephrine-stimulated lipolysis in vivo in three intra-abdominal adipose tissues (ATs: retroperitoneal......, parametrial, and mesenteric) and in subcutaneous AT, and we also studied the effect of physical training. Moreover, we studied the effect of physical training on epinephrine-stimulated lipolysis in muscle in vivo. Female rats were either swim trained (15 wk, n = 8) or sedentary (n = 7). Under anesthesia......, a two-stage intravenous epinephrine infusion (60 min of 80 and 200 ng. kg(-1). min(-1), respectively) was carried out, and local interstitial glycerol concentration was measured by the microdialysis technique. Blood flow was measured by microspheres. Training increased blood flow in all ATs [on average...

    Fluid collections are commonly seen following orthotopic liver transplantation. The majority of these collections are not infected and resolve spontaneously. However, infected collections are associated with significant morbidity and mortality and usually require drainage. Clinical signs of infection are frequently masked following transplantation due to immunosuppression. Intrahepatic collections usually represent abscesses or bilomas and invariably require intervention. Altered anatomical relationships result in signs that frequently help to differentiate these from loculated fluid within hepatic fissures. Other imaging features indicating infection include the presence of gas where none was seen previously, the development of a discrete wall and changes in the surrounding liver. This article aims to identify sonographic and computed tomographic features which differentiate those collection that require drainage from those can be left to resolve spontaneously. 13 refs., 8 figs.

    Full Text Available Abstract The CIAO Study (“Complicated Intra-Abdominal infection Observational” Study is a multicenter investigation performed in 68 medical institutions throughout Europe over the course of a 6-month observational period (January-June 2012. Patients with either community-acquired or healthcare-associated complicated intra-abdominal infections (IAIs were included in the study. 2,152 patients with a mean age of 53.8 years (range: 4–98 years were enrolled in the study. 46.3% of the patients were women and 53.7% were men. Intraperitoneal specimens were collected from 62.2% of the enrolled patients, and from these samples, a variety of microorganisms were collectively identified. The overall mortality rate was 7.5% (163/2.152. According to multivariate analysis of the compiled data, several criteria were found to be independent variables predictive of patient mortality, including patient age, the presence of an intestinal non-appendicular source of infection (colonic non-diverticular perforation, complicated diverticulitis, small bowel perforation, a delayed initial intervention (a delay exceeding 24 hours, sepsis and septic shock in the immediate post-operative period, and ICU admission. Given the sweeping geographical distribution of the participating medical centers, the CIAO Study gives an accurate description of the epidemiological, clinical, microbiological, and treatment profiles of complicated intra-abdominal infections (IAIs throughout Europe.

  5. Laparoscopic intra-abdominal ligation and removal of cryptorchid testes in horses.

    1998-03-01

    Laparoscopic intra-abdominal ligation and removal of cryptorchid testes in horses was evaluated retrospectively in 50 horses that underwent the procedure between 1991 and 1996. Sixty-one cryptorchid testes were removed by one of the following methods; the use of 1) an endoscoping stapling and transection device, 2) an endoscopic clipping device, 3) an endoscopic ligating loop. Monopolar electrosurgery was combined with these methods to facilitate coagulation and cutting of tissue. In 8 horses, 9 testes were retained between the internal and external inguinal rings. The inguinal testes were removed by cutting the internal inguinal ring and bringing the testis back into the abdomen for removal. No attempt was made to close the internal inguinal ring. The most frequently employed and most cost effective method for laparoscopic intra-abdominal removal of cryptorchid testes in this study was the combined use of an endoscopic ligating loop and monopolar electrosurgery. One intra-operative complication (perforation of the small intestine) occurred and was dealt with successfully. One horse developed a fever attributed to upper respiratory tract infection post operatively and was treated successfully with antibiotic. Intra-abdominal ligation and transection of cryptorchid testes is an effective method for cryptorchid castration. This technique minimises the loss of insufflation, allows inspection of the cut tissue for haemorrhage and offers secure closure of the abdominal wall preventing inguinal herniation and excellent visualisation of the cryptorchid testis.

  6. Intra-abdominal hypertension in fulminant Clostridium difficile infection--an under-recognized treatable complication.

    Clostridium difficile is the most common cause of nosocomial infectious diarrhea in adults, with recent reports of increased severity and case fatality. Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are increasingly recognized and treatable complications of severe illness in medical patients, and are independent predictors of mortality. Patients with severe Clostridium difficile infection (CDI) are at increased risk for IAH and ACS. However, ACS has been only rarely described in this population. We report a case of a 61 year-old morbidly obese, chronically ill, ventilator dependent patient, who developed fulminant CDI, including progressive colonic distension, acute renal failure and intra-abdominal fluid sequestration. Her clinical course worsened abruptly, with new shock, worsening hypoxic respiratory failure, increased peak airway pressures and reduced tidal volumes. Intra-abdominal pressure was 30 mm Hg. The patient was not considered a surgical candidate, was refractory to escalating non-surgical support, and died following withdrawal of life support. Although patients with fulminant CDI share many risk factors for IAH and ACS, these conditions were rarely reported in this population and are likely under recognized, as was the case with the present patient. Increased vigilance for IAH is needed in this at-risk population.

    Pylephlebitis or septic thrombophlebitis of the portal venous system is a rare but serious complication of intra-abdominal infections which drain into the portal venous system. Its diagnosis is based on clinical suspicion and imaging tests, mainly a computed tomography scan, given the lack of specificity of the signs and symptoms. Spread of septic emboli is the major cause of morbidity and mortality. The aim of the study was to analyse patients diagnosed in our hospital. Retrospective descriptive study of patients diagnosed with pylephlebitis in our hospital. Four patients were included, 3 men and one woman. In 3 cases it was acute cholecystitis that led to the diagnosis of pylephlebitis at the same time as the intra-abdominal infection. Emergency surgery was performed in one case, whilst the other 2 were treated conservatively. Blood cultures were performed in all cases, and empirical antibiotic treatment was used. In the only case of acute appendicitis, diagnosis of pylephlebitis was achieved during the study of postoperative fever, with empirical antibiotic treatment also being started. The haematologist was requested to start the required anticoagulation therapy in all cases. Pylephlebitis is a rare complication of intra-abdominal infections that may make lead to a worse outcome. A high level of suspicion is required as well as imaging tests to make an early diagnosis and appropriate treatment. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    Full Text Available Postoperative intra-abdominal adhesion is a very common complication after abdominal surgery. One clinical problem that remains to be solved is to identify an ideal strategy to prevent abdominal adhesions. Keratinocyte growth factor (KGF has been proven to improve the proliferation of mesothelial cells, which may enhance fibrinolytic activity to suppress postoperative adhesions. This study investigated whether the combined administration of KGF and a sodium hyaluronate (HA gel can prevent intra-abdominal adhesions by improving the orderly repair of the peritoneal mesothelial cells. The possible prevention mechanism was also explored. The cecum wall and its opposite parietal peritoneum were abraded after laparotomy to induce intra-abdominal adhesion formation. Animals were randomly allocated to receive topical application of HA, KGF, KGF + HA, or normal saline (Control. On postoperative day 7, the adhesion score was assessed with a visual scoring system. Masson’s trichrome staining, picrosirius red staining and hydroxyproline assays were used to assess the magnitude of adhesion and tissue fibrosis. Cytokeratin, a marker of the mesothelial cells, was detected by immunohistochemistry. The levels of tissue plasminogen activator (tPA, interleukin-6 (IL-6, and transforming growth factor β1 (TGF-β1 in the abdominal fluid were determined using enzyme-linked immunosorbent assays (ELISAs. Western blotting was performed to examine the expression of the TGF-β1, fibrinogen and α-smooth muscle actin (α-SMA proteins in the rat peritoneal adhesion tissue. The combined administration of KGF and HA significantly reduced intra-abdominal adhesion formation and fibrin deposition and improved the orderly repair of the peritoneal mesothelial cells in the rat model. Furthermore, the combined administration of KGF and HA significantly increased the tPA levels but reduced the levels of IL-6, tumor necrosis factor α (TNF-α and TGF-β1 in the abdominal fluid. The

    2016-05-01

    Full Text Available BACKGROUND AND AIMS Increased intra-abdominal pressure (IAP, also referred to as intra-abdominal hypertension (IAH, affects organ function in critically ill patients. The prevalence of IAH is between 32% - 65% in intensive care units. Normal IAP is ≈ 5–7 mmHg. According to WSACS definition, IAH = IAP ≥12 mmHg and is divided into 4 grades. They are Grade I (12-15 mmHg, Grade II (16-20 mmHg, Grade III (21-25 mmHg, Grade IV (>25 mmHg. Transvesical measurement of IAP currently is the most popular technique. Several systems with or without the need for electronic equipment are available that allow IAP measurement. The aim is to study the incidence of IAH in critically ill patients, to assess the risk factors for development of IAH, to study the role of IAH as a risk factor for Acute Kidney Injury (AKI, to assess the role of IAH as a risk factor for increased (Intensive Care Unit ICU mortality. SUBJECTS AND METHODS This is a prospective observational study. Study period was six months. The study included 52 patients admitted to Medical ICU in Government Medical College, Kozhikode, Kerala. RESULTS AND CONCLUSION There was a very high incidence of intra-abdominal hypertension in critically ill patients. IAH was significantly associated with risk factors like sepsis, mechanical ventilation, pancreatitis, capillary leak, ascites, cumulative fluid balance and cirrhosis. IAH is an independent risk factor for development of acute kidney injury. IAH is an independent predictor of mortality in critically ill patients.

    2016-02-01

    Full Text Available Antimicrobial stewardship programs (ASPs focus on improving the utilization of broad spectrum antibiotics to decrease the incidence of multidrug-resistant Gram positive and Gram negative pathogens. Hospital admission for both medical and surgical intra-abdominal infections (IAIs commonly results in the empiric use of broad spectrum antibiotics such as fluoroquinolones, beta-lactam beta-lactamase inhibitors, and carbapenems that can select for resistant organisms. This review will discuss the management of uncomplicated and complicated IAIs as well as highlight stewardship initiatives focusing on the proper use of broad spectrum antibiotics.

    The insertion of sewing needles into the abdominal cavity is an uncommon form of child abuse. We report a 2-and-a-half-year-old boy with 2 intra-abdominal sewing needles that were discovered during the evaluation of chronic abdominal pain and vomiting. This case report illustrates the wide range with which abusive injury can present in children. Pediatricians need to be alerted to this newly-recognized and the increasing form of child abuse so that they examine and diagnose their patients appropriately.

    We derive and validate clinical prediction rules to identify adult patients at very low risk for intra-abdominal injuries after blunt torso trauma. We prospectively enrolled adult patients (>or=18 years old) after blunt torso trauma for whom diagnostic testing for intra-abdominal injury was performed. In the derivation phase, we used binary recursive partitioning to create a rule to identify patients with intra-abdominal injury who were undergoing acute intervention (including therapeutic laparotomy or angiographic embolization) and a separate rule for identifying patients with any intra-abdominal injury present. We considered only clinical variables readily available with acceptable interrater reliability. The prediction rules were then prospectively validated in a separate cohort of patients. In the derivation phase, we enrolled 3,435 patients, including 311 (9.1%; 95% confidence interval [CI] 8.1% to 10.1%) with intra-abdominal injury and 109 (35.0%; 95% CI 29.7% to 40.6%) with intra-abdominal injury requiring acute intervention. In the validation study, we enrolled 1,595 patients, including 143 (9.0%; 95% CI 7.6% to 10.5%) with intra-abdominal injury. The derived rule for patients with intra-abdominal injuries who were undergoing acute intervention consisted of hypotension, Glasgow Coma Scale (GCS) score less than 14, costal margin tenderness, abdominal tenderness, hematuria level greater than or equal to 25 red blood cells/high powered field, and hematocrit level less than 30% and identified all 44 patients in the validation phase with intra-abdominal injury who were undergoing acute intervention (sensitivity 44/44, 100%; 95% CI 93.4% to 100%). The derived rule for the presence of any intra-abdominal injury consisted of GCS score less than 14, costal margin tenderness, abdominal tenderness, femur fracture, hematuria level greater than or equal to 25 red blood cells/high powered field, hematocrit level less than 30%, and abnormal chest radiograph result

Although not an antibiotic in a new class, it offers a glimmer of hope in combating serious infections secondary to multidrug-resistant Gram-negative bacteria when we have not seen a new class of antibacterial, particularly for Gram-negative bacteria, for more than 10 years. In vitro, doripenem exhibits a broad spectrum of activity against Gram-positive and Gram-negative bacteria, including extended-spectrum β-lactamase (ESBL and Amp-C β-lactamase producing Enterobacteriaceae and anaerobes. Doripenem also exhibits better in vitro activity against Pseudomonas aeruginosa compared to other anti-pseudomonal carbapenems. It combines the desirable activities of both imipenem and meropenem. It has similar activity to imipenem against Gram-positive pathogens and has the antimicrobial spectrum of meropenem against Gram-negative organisms. Several randomized clinical trials have demonstrated that doripenem is non-inferior to meropenem, imipenem, piperacillin/tazobactam, or levofloxacin in its efficacy and safety profile in treating a wide range of serious bacterial infections including intra-abdominal infection, complicated urinary tract infection, and nosocomial pneumonia. Due to its wide spectrum of activity and good safety profile it is susceptible to misuse leading to increasing rates of resistance

Gram-negative organisms including Enterobacteriaceae and Pseudomonas aeruginosa are some of the most concerning threats due to their resistance mechanisms: extended-spectrum beta-lactamase production and Klebsiella pneumoniae carbapenemase enzymes. Ceftazidime is a third-generation broad-spectrum cephalosporin with activity against P. aeruginosa and avibactam is a novel nonbeta-lactam beta-lactamase inhibitor. Avycaz®, the trade name for this new combination antibiotic, restores the activity of ceftazidime against some of the previously resistant pathogens. Avycaz was approved in 2015 for the treatment of complicated urinary tract infections, including pyelonephritis, and complicated intra-abdominal infections with the addition of metronidazole in patients with little to no other treatment options. This review article assesses the clinical trials and data that led to the approval of this antibiotic, in addition to its spectrum of activity and limitations.

    to evaluate the association between serum levels of procalcitonin and C-reactive protein, on the first 3 postoperative days, and the appearance of postoperative intra-abdominal infection. Prospective observational study including 67 patients operated on for colo-rectal, gastric and pancreatic cancer. Serum levels of procalcitonin and C-reactive protein were analyzed before surgery and daily until the third postoperative day. Values of procalcitonin (PCT) and C-reactive protein (CRP) were recorded as well as their accuracy for detection of postoperative intra-abdominal infection (PIAI). The incidence of postoperative intra-abdominal infection was 13.4%. CRP serum levels at 72h, PCT serum levels at 24, 48 and 72h and the ratio between serum levels of CRP at 72hours and serum levels of CRP at 48hours (CRP D3/CRP D2) were significantly associated with the appearance of postoperative intra-abdominal infection. The highest sensitivity corresponded to PCT at 72hours (88.9%); the highest specificity and positive predictive value corresponded to the ratio CRP D3/CRP D2 (96.49% and 71.4%, respectively); the highest negative predictive value to procalcitonin at 72h and 24h. Serum levels of PCT are significantly associated with the appearance of postoperative intra-abdominal infection. Sensitivity and predictive positive values are low, but negative predictive value is high, even at 24h after surgery. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

    Full Text Available Background. We aimed to describe the incidence of intra-abdominal hypertension (IAH and gastrointestinal (GI symptoms and related outcome in mechanically ventilated (MV patients. Methods. Intra-abdominal pressure (IAP and gastric residual volumes were measured at least twice daily. IAH was defined as a mean daily value of IAP≥12 mmHg. Results. 398 patients were monitored for all together 2987 days. GI symptom(s occurred in 80.2% patients. 152 (38.2% patients developed IAH. Majority (93.4% of patients with IAH had GI symptoms. The more severe IAH was associated with the higher number of concomitant GI symptoms (P<.001. 142 (35.7% patients developed both IAH and at least one GI symptom at any time in ICU, and in 77 patients they occurred simultaneously on the same day. This subgroup had the highest ICU mortality (21.8%. In contrast, the small group of patients presenting only IAH, but not GI symptoms (10 patients, had no lethal outcome. Three patients (4.4% died without showing either IAH or GI symptoms. Conclusions. GI symptoms and IAH often, but not always, occur together. The patients having IAH solely without developing GI symptoms have rather good outcome.

    AIM: This study aims to evaluate the algorithm of procalcitonin (PCT) and its role on the duration of antibiotics prescription for intra-abdominal infections. MATERIALS AND METHODS: This study is a prospective controlled study that is conducted in groups of 50 hospitalised patients and 50 controlled group patients. RESULTS: The results indicated that the average duration of antibiotic delivery to the PCT group was -10.6 days (SD ± 6.6 days), while in the control group -13.2 days (SD ± 4.2 days). These data showed a significant difference in the duration of antibiotic therapy and the monitoring role of PCTs in the prediction success of antibiotic treatment. The antibiotic delivery was longer in the septic shock 17 (SD ± 11.7) that corresponds to high PCT values of 67.8 (SD ± 50.9). Recurrence of the infection after the cessation of antibiotics occurred in 2 cases (4%) in the standard group, while it occurred in 3 cases (6%) in the control group. CONCLUSION: The treatment of the intra-abdominal infections based on the PCT algorithm shortens the duration of antibiotic treatment and does not pose a risk for the recurrence of the infection.

    Full Text Available Background : Studies have documented the impact of intra-abdominal hypertension (IAH on virtually every organ. However, it still remains strangely underdiagnosed. The aims of the study were to assess, in patients undergoing emergency laparotomy, whether intra-abdominal pressure (IAP is an independent predictor of morbidity and mortality, to evaluate the effects of IAH, and to identify hidden cases of abdominal compartment syndrome (ACS. Materials and Methods : The study comprised 197 patients undergoing emergency laparotomy. IAP was measured preoperatively and then postoperatively at 0, 6, and 24 hours. Duration of hospital stay, occurrence of burst abdomen, and mortality were noted as outcomes. Results : At admission, incidence of IAH was 80%. No significant association was found between IAP and occurrence of burst abdomen (P > 0.1. IAP was found to be a significant predictor of mortality in patients undergoing laparotomy (P < 0.001. Elevated IAP was found to affect all the organ systems adversely. The incidence of post-op ACS was 3.05% in the general population and 13.16% in trauma patients. The mortality rate for this subgroup was 100%. Conclusions : IAP is a significant predictor of mortality in patients undergoing laparotomy. IAH has detrimental effects on various organ systems. A more frequent monitoring with prompt decompression may be helpful in decreasing the mortality rate. Further studies are required to establish a screening protocol in patients undergoing laparotomy to detect and manage cases of IAH and ACS.

  20. Increased pressure within the abdominal compartment: intra-abdominal hypertension and the abdominal compartment syndrome.

    Roberts, Derek J; Ball, Chad G; Kirkpatrick, Andrew W

    2016-04-01

    This article reviews recent developments related to intra-abdominal hypertension (IAH)/abdominal compartment syndrome (ACS) and clinical practice guidelines published in 2013. IAH/ACS often develops because of the acute intestinal distress syndrome. Although the incidence of postinjury ACS is decreasing, IAH remains common and associated with significant morbidity and mortality among critically ill/injured patients. Many risk factors for IAH include those findings suggested to be indications for use of damage control surgery in trauma patients. Medical management strategies for IAH/ACS include sedation/analgesia, neuromuscular blocking and prokinetic agents, enteral decompression tubes, interventions that decrease fluid balance, and percutaneous catheter drainage. IAH/ACS may be prevented in patients undergoing laparotomy by leaving the abdomen open where appropriate. If ACS cannot be prevented with medical or surgical management strategies or treated with percutaneous catheter drainage, guidelines recommend urgent decompressive laparotomy. Use of negative pressure peritoneal therapy for temporary closure of the open abdomen may improve the systemic inflammatory response and patient-important outcomes. In the last 15 years, investigators have better clarified the pathogenesis, epidemiology, diagnosis, and appropriate prevention of IAH/ACS. Subsequent study should be aimed at understanding which treatments effectively lower intra-abdominal pressure and whether these treatments ultimately affect patient-important outcomes.

    In our present study, we aimed to evaluate the effects of taurolidine, a blocking agent of fibrin deposition, and icodextrin, a colloid osmotic material that also inhibits fibrin accumulation, and the effect of their application separately and concomittantly in intra-abdominal adhesion prevention. Forty BALB/c male mice, weighing 30-35 g and 11-12 weeks old were divided into four groups as follows: group 1: control group, group 2: taurolidine group, group 3: icodextrin group, and group 4: taurolidine and icodextrin group. Animals were sacrificed by cervical dislocation after 14 days. The adhesions were classified and scored by two blinded researchers according to Nair's macroscopic adhesion staging system and microscopically evaluated using Zuhlke classification system. In group 2 there was no mice with score 4. In group 3, scores 3 and 4 were absent. Scores 2, 3, and 4 were not detected in group 4. The mean value of adhesion scores decreased from groups 1 to 4. There was a significant statistical difference between all the groups and group 1. There was no change between the study groups on macroscopic examination, whereas histopathological examination revealed statistically significance between group 4 and other groups. Taurolidine and icodextrin, when used alone or together, decrease postoperative intra-abdominal adhesion formation. Macroscopic appearence was not supportive of statistical difference between group 4 and other groups. Microscopic evaluation paves the road for future studies for determining significance when taurolidine and icodextrin are applied concomittantly. Additional experimental studies are required for dose adjustment.

    Intra-abdominal infections are associated with significant morbidity and mortality. The most frequent pathogens involved are the gastrointestinal flora which can cause poly-microbial infections. Microbiological diagnosis is required to determine the aetiology and antimicrobial susceptibility of the organisms involved. Prompt initiation of antimicrobials is essential for improving patient's outcome. Knowledge of local trends of antimicrobial resistance in nosocomial isolates is essential for empiric therapy. Methods: A total of 190 clinical isolates collected from intra-abdominal infections during July 2013 to July 2014 were included in the study. Organism identification and Antimicrobial sensitivity testing using standard biochemical tests and CLSI recommended criteria was carried out. Result: Of the total 190 isolates from abdominal infection sources 52% were from fluid sources (peritoneal and ascitic fluid), 41% were from gall bladder and 6.5% were from other abdominal sources. E. coli (46.8%) was the most frequently isolated gram negative and Enterococcus (13.1%) was the most frequently isolated gram positive organism. Carbapenem (imipenem) was the most active agent against enterobacteraceae exhibiting, 94.4% and 91.3% sensitivity against E. coli and Klebsiella respectively. While vancomycin was the most active agent against gram positive organisms. Eighty-four percent of the Enterococci isolated were sensitive to vancomycin. Most isolates exhibited resistance to one or more antibiotics. Conclusion: Continuous evolution of antimicrobial resistance patterns in bacteria necessitates updating of local data on antimicrobial susceptibility profiles to ensure the safety and efficacy of pathogen specific antimicrobial therapies.

    Full Text Available ABSTRACT: Intraoperative ultrasonography (IOUS is used in medicine for diagnosis and guidance during oncologic surgery. The aims of this study were to assess the performance, feasibility, advantages and difficulties of the IOUS technique in dogs with suspected intra-abdominal tumors. The study included nine client-owed dogs that had suspected intra-abdominal tumors (spleen, liver or bowel based on transabdominal ultrasound examination and that were subsequently referred for exploratory laparotomy surgery. During surgery, IOUS was performed; results of preoperative transabdominal ultrasonography, inspection by the surgeon and IOUS were compared on a case-by-case basis. IOUS was helpful in determining lesion resection in all cases. Lesions detected solely by the use of IOUS were observed in seven out of nine cases. Analysis of these cases demonstrated that IOUS can be a tool to assist during oncology surgery on the liver, spleen or bowel. Dogs with hepatic tumors can have small non-palpable intraparenchymal nodules, which may be visible by IOUS.

    Heterotopic ossification, an entity common in orthopaedic practice frequently involving the hip, knee or other joints, is rarely encountered in abdominal wounds and mesentery. This unusual condition, referred to as mesenteric ossification, is typically associated with intra-abdominal catastrophes. Surgical repair following such catastrophes has always been a challenge as the abdominal wall architecture is frequently distorted by the multiple laparotomies previously performed. In addition, the presence of several enterocutaneous fistulae further compounds the reconstruction approach, especially when mesh material is planned for use. We report a case of intra-abdominal heterotopic ossification with mesenteric involvement after a penetrating injury to the abdomen, followed by multiple laparotomies that ended in a complex abdominal wall hernia with major loss of domain, and multiple enterocutaneous fistulae. The patient was treated with resection of the bony deposits from the abdominal wound and cavity, along with excision of the fistula sites. This was followed by a component separation technique and the use of a biologic mesh graft to reconstruct the abdominal wall.

The drug is started at a low dose and gradually increased to a target dose of 300–450 mg/day. It is well known to cause agranulocytosis and neutropenia. Several cases of fatal sepsis have been reported in neutropenic patients and emphasis is placed on monitoring for agranulocytosis; however, clozapine also causes intestinal hypomotility and constipation, which if unrecognized can lead to intestinal obstruction, bowel necrosis, and intra-abdominal sepsis. Reduced behavioral pain reactivity in schizophrenics may alter the ability to express pain, potentially leading to a delay in the presentation for medical attention. We report a case of fatal intra-abdominal sepsis secondary to an unrecognized case of clozapine-related constipation.

    Standing laparoscopic procedures, facilitated by abdominal insufflation with carbon dioxide, are being employed to an increasingly greater extent in horses. However, a sustained increase in abdominal pressure may be life-threatening. A practical method for intra-abdominal pressure (IAP) assessment is imperative. Although indirect methods for estimating IAP have been extensively studied in man, little work has been performed in veterinary medicine. To investigate the utility of gastric manometry for purposes of evaluating IAP in horses. Gastric pressure (P(ga) ) was estimated by balloon manometry in 8 healthy, mature horses, before and during a 30 min passive pneumoperitoneum induced by right paralumbar puncture. The balloon manometer was positioned within the gastric lumen and inflated using 2 separate volumes of air: 10 and 50 ml. P(ga) Gastric pressure was determined at baseline (0) and 5, 15 and 30 min after induction of passive pneumoperitoneum. Intra-abdominal pressure was measured directly by right paralumbar puncture using an 8 gauge needle at baseline and immediately following establishment of passive pneumoperitoneum. Baseline IAP values were negative and increased (P≤0.05) during development of passive pneumoperitoneum. However, recorded P(ga) measurements for both inflation volumes were positive before (baseline) and during the course of the passive pneumoperitoneum. Measured P(ga) values did not correlate with IAP at any time. Our results suggest that the indirect method used in human patients for estimating IAP by P(ga) is not applicable for horses. © 2011 EVJ Ltd.

    Complications secondary to oxygen-ozone therapy are rare, but they have been described in medical literature. There are only two cases of infectious complications after oxygen-ozone therapy. Our aim is to describe a rare case of purulent complication that was secondary to oxygen-ozone therapy for the treatment of lower back pain. We report the clinical improvement with conservative treatment for a local complication after percutaneous oxygen-ozone treatment. According to the clinical improvement of our patient, conservative treatment should be considered before any aggressive surgery. Copyright © 2013 SECOT. Published by Elsevier Espana.

  8. Common errors in the treatment of intra-abdominal infections: the irrational use of antimicrobial agents

    Full Text Available Antimicrobial resistance (AR is a global, emergent problem because an increasing numbers of serious community acquired and nosocomial infections are caused by resistant bacterial pathogens. It is a direct consequence of the excessive and irrational use of antibiotics. The use of antimicrobial agents – aimed to decrease morbidity and mortality rate related to intra-abdominal infections – is very high, often improper, in the Departments of General and Emergency Surgery and Intensive Cure Units. Source control and empiric antibiotic therapy have to be administrated as early as possible to decrease high mortality rates in patients with severe sepsis or septic shock and, in this, the general surgeon has a crucial role. Proper antimicrobial stewardship in selecting an appropriate antibiotic and optimizing its dose and duration to cure intraabdominal infections may prevent the emergence of AR and decrease costs for antibiotics.

    Infection of pancreatic necrosis, although present in less than 10% of acute pancreatitis, carries a high risk of mortality; debridment and drainage of necrosis is the treatment of choice, followed by 'open' or 'close' abdomen management. We recently introduced the use of intra-abdominal vacuum sealing after a classic necrosectomy and laparostomy. Two patients admitted to ICU for respiratory insufficiency and a diagnosis of severe acute pancreatitis developed pancreatic necrosis and were treated by necrosectomy, lesser sac marsupialisation and posterior lumbotomic opening. Both of the patients recovered from pancreatitis and a good healing of laparostomic wounds was obtained with the use of the VAC system. Most relevant advantages of this technique seem to be: the prevention of abdominal compartment syndrome, the simplified nursing of patients and the reduction of time to definitive abdominal closure. © 2010 The Authors.

    Kikuchi's disease is a self-limiting benign disease characterized by cervical lymphadenopathy, but it can be mistaken for malignant disease, and when involved lymph nodes are unusually located, diagnosis can be more difficult. The authors report the case of a 19-year-old man with Kikuchi's disease, who had isolated intraabdominal lymphadenopathy and increased 18-fluoro-deoxyglucose (FDG) uptake in positron emission tomography computed tomography (PET-CT). Although its incidence is extremely rare, intra-abdominal Kikuchi's disease with increased FDG uptake in PET-CT image should be considered in the differential diagnosis when constitutional symptoms mimic those of malignant lymphoma.

  11. Effects of anabolic steroids on acute phase responses in intra-abdominal sepsis

    Full Text Available The acute phase response is an important adaptive response to sepsis and injury. As anabolic steroids increase protein synthesis we postulated that these agents might also increase hepatic acute phase protein synthesis. Male Wistar rats were pretreated with testosterone or danazol for 48 h prior to caecal ligation and puncture (CLP. Thirty-six h following surgery the animals were killed and blood taken for full blood count, total protein, albumin, α, β and γ globulin fractions on serum electrophoresis, complement C3 and transferrin levels. Danazol increased the α1, α2 and β1 globulin serum protein fractions in comparison with no surgery and CLP alone groups. These results indicate that danazol increases plasma acute phase proteins, as measured by electrophoresis, in this model of intra-abdominal sepsis.

    Full Text Available Bilateral cryptorchidism is a rare occurrence and seminoma is the most common germ cell tumor found in undescended testes when they occur. We present the case of a patient with bilateral cryptorchidism who presented to our trauma center after a motor vehicle collision and was found incidentally to have a 17-cm intra-abdominal mass. The mass was subsequently biopsied and proven to be seminoma. The patient completed three cycles of bleomycin/etoposide/cisplatin chemotherapy and successfully underwent a postchemo retroperitoneal lymph node dissection with no viable residual tumor or positive lymph nodes found in the surgical specimen. He also had an orchiopexy of the contralateral testicle. The patient recovered fully and has been found to be recurrence-free four months postoperatively. We highlight the importance of cisplatin-based chemotherapy and extensive tumor resection as the mainstay of initial cancer control.

    No conclusive results on the efficacy and timing of open abdomen (OA) are available, particularly in the setting of intra-abdominal infections. We analyzed outcomes and risk factors retrospectively in a large series of patients managed with an OA during the past 20 y in an effort to clarify this issue. We reviewed the records of 133 patients who underwent treatment with an OA, considering factors related to patient, disease, medical management, and surgical treatment. The end points of the bi-variable analysis were 1-y mortality, calculated from the time of an initial OA procedure, and definitive fascial closure. Most patients (112/133) managed with an OA had one of several types of peritonitis. Many patients had severe clinical conditions (mean Acute Physiology and Chronic Health Evaluation [APACHE] II score was almost 9 points for the study population). With regard to surgical management, the mean (+SD) number of abdominal revisions was 5.9+9.3 during a mean duration of treatment with an OA of 14.3+11.6 d. The overall mortality in the study was 26% (35/133). Bi-variable analysis revealed factors associated with overall mortality to be age, renal and respiratory co-morbidities, edema on an initial chest radiograph, blood pressure, blood glucose and creatinine concentrations; and APACHE II score. The rate of definitive fascial closure was 75% (100/133). Factors associated negatively with fascial closure were respiratory co-morbidity, edema on a first chest radiograph, post-operative mesenteric ischemia as an indication for OA, blood glucose and creatinine concentrations, and duration of an OA. Patients' pre-operative clinical status influences strongly their response to surgical treatment. The management of OA does not affect adversely the survival of patients with intra-abdominal infections, but factors related to the management of OA (duration of OA) seem to affect the possibility of definitive fascial closure.

    Abdominal Compartment Syndrome (ACS) is an uncommon but deleterious complication after trauma laparotomy. Early recognition of patients at risk of developing ACS is crucial for their outcome. The aim of this study was to compare the characteristics of patients who developed high-grade intra-abdominal hypertension (IAH) (i.e., grade III or IV; intra-abdominal pressure, IAP >20 mm Hg) following an injury-related laparotomy versus those who did not (i.e., IAP ≤20 mm Hg). A retrospective analysis of consecutive trauma patients admitted to a level 1 trauma centre in Australia between January 1, 1995 and January 31, 2010 was performed. A comparison was made between characteristics of patients who developed high-grade IAH following trauma laparotomy versus those who did not. A total of 567 patients (median age 31 years) were included in this study. Of these patients 10.2% (58/567) developed high-grade IAH of which 51.7% (30/58) developed ACS. Patients with high-grade IAH were older (pgrade IAH received larger volumes of crystalloids (pgrade IAH suffered higher mortality rates (25.9% (15/58) vs. 12.2% (62/509); p=0.012). Of all patients who underwent a trauma laparotomy, 10.2% developed high-grade IAH, which increases the risk of mortality. Patients with acidosis, coagulopathy, and hypothermia were especially at risk. In these patients, the abdomen should be left open until adequate resuscitation has been achieved, allowing for definitive surgery. This is a level III retrospective study.

    Little information is available on the distribution of antimicrobial resistance genes in anaerobes in Japan. To understand the background of antimicrobial resistance in anaerobes involved in intra-abdominal infections, we investigated the distribution of eight antimicrobial resistance genes (cepA, cfiA, cfxA, ermF, ermB, mefA, tetQ, and nim) and a mutation in the gyrA gene in a total of 152 organisms (Bacteroides spp., Prevotella spp., Fusobacterium spp., Porphyromonas spp., Bilophila wadsworthia, Desulfovibrio desulfuricans, Veillonella spp., gram-positive cocci, and non-spore-forming gram-positive bacilli) isolated between 2003 and 2004 in Japan. The cepA gene was distributed primarily in Bacteroides fragilis. Gene cfxA was detected in about 9 % of the Bacteroides isolates and 75 % of the Prevotella spp. isolates and did not appear to contribute to cephamycin resistance. Two strains of B. fragilis contained the metallo-β-lactamase gene cfiA, but they did not produce the protein product. Gene tetQ was detected in about 81, 44, and 63 % of B. fragilis isolates, other Bacteroides spp., and Prevotella spp. isolates, respectively. The ermF gene was detected in 25, 13, 56, 64, and 16 % of Bacteroides spp., Prevotella spp., Fusobacterium spp., B. wadsworthia, and anaerobic cocci, respectively. Gene mefA was found in only 10 % of the B. fragilis strains and 3 % of the non-B. fragilis strains. Genes nim and ermB were not detected in any isolate. Substitution at position 82 (Ser to Phe) in gyrA was detected in B. fragilis isolates that were less susceptible or resistant to moxifloxacin. This study is the first report on the distribution of resistance genes in anaerobes isolated from intra-abdominal infections in Japan. We expect that the results might help in understanding the resistance mechanisms of specific anaerobes.

  17. Relationship between ventral hernia defect area and intra-abdominal pressure: dynamic in vivo measurement.

    It is an acceptable concept that the ventral hernia defect area will increase with a rise in intra-abdominal pressure (IAP). The literature lacks the evidence about how much this increase is in vivo. The aim of this study was to objectively measure the change in the ventral hernia defect area with increasing intra-abdominal pressure. In a prospective study of laparoscopic ventral hernia repair, the area of hernia defect was measured from inside the abdomen using a sterile paper ruler. The horizontal (width) and vertical (length) measurements of the defect were taken at two pressure points: (IAP = 8 mmHg) and (IAP = 15 mmHg). The hernia defect area was calculated as an oval shape using a standard formula. Eighteen consecutive patients with a ventral hernia were included in this study (8 males: 10 females). Median age was 60 years (30-81), body mass index (BMI) was 29.9 (22.6-37.6). Changing the IAP significantly, (P hernia defect. The median calculated defect area, as an oval shape, was 5.6 cm(2) (Q1-Q3 = 3.5-15.5) and 6.9 cm(2) (Q1-Q3 = 4.5-18.7) at 8 and 15 mmHg IAP, respectively. The calculated area of mesh required to cover the defect with a 5 cm overlap increased by a median of 5% (Q1-Q3 = 3-6%). The change in defect area did not differ significantly between obese and non-obese patients (P = 0.5). Dynamic, rather than static, measurements of ventral hernia area during laparoscopy provide a simple way of in vivo objective measurement that helps the surgeon choose the appropriate area of mesh. When choosing mesh area, we support the trend toward a larger overlap of at least 5 cm if less precise methods of measuring defect area are been used.

    Cresswell, A G

    1993-01-01

    The purpose of this study was to determine and compare interactions between the abdominal musculature and intra-abdominal pressure (IAP) during controlled dynamic and static trunk muscle loading. Myoelectric activity was recorded in six subjects from the rectus abdominis, obliquus externus, obliquus internus, transversus abdominis and erector spinae muscles using surface and intra-muscular fine-wire electrodes. The IAP was recorded intra-gastrically. Trunk flexions and extensions were performed lying on one side on a swivel table. An adjustable brake provided different friction loading conditions, while adding weights to an unbraked swivel table afforded various levels of inertial loading. During trunk extensions at all friction loads, IAP was elevated (1.8-7.2 kPa) with concomitant activity in transversus abdominis and obliquus internus muscles--little or no activity was seen from rectus abdominis and obliquus externus muscles. For inertia loading during trunk extension, IAP levels were somewhat lower (1.8-5.6 kPa) and displayed a second peak when abdominal muscle activity occurred in the course of decelerating the movement. For single trunk flexions with friction loading, IAP was higher than that seen in extension conditions and increased with added resistance. For inertial loading during trunk flexion, IAP showed two peaks, the larger first peak matched peak forward acceleration and general abdominal muscle activation, while the second corresponded to peak deceleration and was accompanied by activity in transversus abdominis and erector spinae muscles. It was apparent that different loading strategies produced markedly different patterns of response in both trunk musculature and intra-abdominal pressure.

    The pathogenesis of intra-abdominal candidiasis is poorly understood. Mice were intraperitoneally infected with Candida albicans (1 × 10(6) colony-forming units) and sterile stool. nanoString assays were used to quantitate messenger RNA for 145 C. albicans genes within the peritoneal cavity at 48 hours. Within 6 hours after infection, mice developed peritonitis, characterized by high yeast burdens, neutrophil influx, and a pH of 7.9 within peritoneal fluid. Organ invasion by hyphae and early abscess formation were evident 6 and 24 hours after infection, respectively; abscesses resolved by day 14. nanoString assays revealed adhesion and responses to alkaline pH, osmolarity, and stress as biologic processes activated in the peritoneal cavity. Disruption of the highly-expressed gene RIM101, which encodes an alkaline-regulated transcription factor, did not impact cellular morphology but reduced both C. albicans burden during early peritonitis and C. albicans persistence within abscesses. RIM101 influenced expression of 49 genes during intra-abdominal candidiasis, including previously unidentified Rim101 targets. Overexpression of the RIM101-dependent gene SAP5, which encodes a secreted protease, restored the ability of a rim101 mutant to persist within abscesses. A mouse model of intra-abdominal candidiasis is valuable for studying pathogenesis and C. albicans gene expression. RIM101 contributes to persistence within intra-abdominal abscesses, at least in part through activation of SAP5.

    To report the occurrence of intra-abdominal injury (IA) in dogs with pelvic fractures due to blunt trauma, to evaluate for association between characterization of pelvic fractures and the presence of IA, and to evaluate for association between IA and other specific clinical conditions. Retrospective case series (2008-2013). University teaching hospital. Eighty-three client-owned dogs with pelvic fractures due to blunt trauma. None. Pelvic injuries included pubic fractures (90.4%), ischial fractures (80.7%), sacroiliac luxations (57.8%), iliac fractures (43.4%), acetabular fractures (30.1%), and sacral fractures (13.3%). Thirty-one dogs (37%) had IA, which included hemoabdomen (27 dogs), uroabdomen (3), and septic abdomen (3); 2 dogs had 2 types of IA. Dogs with sacral fractures were significantly more likely to have IA than dogs without sacral fractures (P = 0.0162). Characterization of pelvic fractures included the direction of compression, presence of a weight-bearing bone fracture, and degree of pelvic narrowing, none of which had an association with IA (P > 0.05). Dogs were more likely to have IA if they had cardiac dysrhythmia (P = 0.0002) or hematuria (P = 0.0001), and were more likely to have a hemoabdomen if they had cardiac dysrhythmia (P = 0.0005). Dogs with hematochezia were more likely to have a septic abdomen (P = 0.0123). Dogs were more likely to receive a transfusion if they had AI (P = 0.033) or hemoabdomen specifically (P = 0.0033). Overall survival to discharge was 89%, which was significantly greater than survival in dogs with pelvic injury that also had septic abdomen (33%; P = 0.0299). IA is common in dogs with pelvic fractures, especially those with sacral fractures. Pelvic fracture characterization had no bearing on the presence of IA. © Veterinary Emergency and Critical Care Society 2016.

    Full Text Available INTRODUCTION: Abdominal compartment syndrome (ACS and intra abdominal hypertension(IAH are common clinical findings in patients with severe acute pancreatitis(SAP. It is thought that an increased intra abdominal pressure(IAP is associated with poor prognosis in SAP patients. But the detailed effect of IAH/ACS on different organ system is not clear. The aim of this study was to assess the effect of SAP combined with IAH on hemodynamics, systemic oxygenation, and organ damage in a 12 h lasting porcine model. MEASUREMENTS AND METHODS: Following baseline registrations, a total of 30 animals were divided into 5 groups (6 animals in each group: SAP+IAP30 group, SAP+IAP20 group, SAP group, IAP30 group(sham-operated but without SAP and sham-operated group. We used a N(2 pneumoperitoneum to induce different levels of IAH and retrograde intra-ductal infusion of sodium taurocholate to induce SAP. The investigation period was 12 h. Hemodynamic parameters (CO, HR, MAP, CVP, urine output, oxygenation parameters(e.g., S(vO(2, PO(2, PaCO(2, peak inspiratory pressure, as well as serum parameters (e.g., ALT, amylase, lactate, creatinine were recorded. Histological examination of liver, intestine, pancreas, and lung was performed. MAIN RESULTS: Cardiac output significantly decreased in the SAP+IAH animals compared with other groups. Furthermore, AST, creatinine, SUN and lactate showed similar increasing tendency paralleled with profoundly decrease in S(vO(2. The histopathological analyses also revealed higher grade injury of liver, intestine, pancreas and lung in the SAP+IAH groups. However, few differences were found between the two SAP+IAH groups with different levels of IAP. CONCLUSIONS: Our newly developed porcine SAP+IAH model demonstrated that there were remarkable effects on global hemodynamics, oxygenation and organ function in response to sustained IAH of 12 h combined with SAP. Moreover, our model should be helpful to study the mechanisms of IAH

    Full Text Available Objective: The metabolic and cardiovascular risk of obesity is predominantly defined through the amount of intra-abdominal fat (IAF. Regarding this risk and the benefits of weight reduction gender-specific differences have been described. The aim of this study was to examine the gender-specific relationship between IAF assessed via ultrasound and the cardiometabolic risk profile in extremely obese adolescents before and after weight loss. Methods: In 107 consecutively admitted adolescents (n = 59 girls, mean age 15.4 ± 2.6 years boys and 15.1 ± 2.1 years girls, mean BMI z-score 3.2 ± 0.6 boys and 3.5 ± 0.6 girls anthropometric and fasting laboratory chemical parameters were measured before and after an in-patient long-term therapy (mean durance 5.6 ± 2.3 months. IAF was determined by measuring the intra-abdominal depth (IAD via ultrasound. Results: IAD was higher in boys as compared to girls (58.0 ± 22.4 mm vs. 51.3 ± 16.0 mm. IAD values were positively associated with BMI-z scores, waist circumferences, HOMA-IR and serum levels of γGT, hs-CRP and IL-6 in both genders. In boys, but not in girls, IAD was significantly correlated with systolic and diastolic blood pressure, serum levels of triglycerides, ALT as well as adiponectin and HDL-cholesterol. After a marked mean weight loss of -27.1 ± 16.2 kg (-20.1 ± 7.9% in boys and of -20.5 ± 11.5 kg (-17.3 ± 7.1% in girls, IAD decreased by -20.7 ± 16.2 mm (--32.4 ± 16.9% in boys and by -18.4 ± 12,7 mm (-34.3 ± 18.4% in girls, resulting in more pronounced ameliorations of cardiovascular risk factors in boys than in girls. Conclusions: The present study indicates that IAF assessed by ultrasound is a good indicator for the cardiometabolic risk factor profile in extremely obese adolescents. Associations between IAF and risk factors are more pronounced in boys than in girls.

    Perforated appendicitis can result in potentially serious complications requiring prolonged medical care. The optimal approach to successfully managing this condition is controversial. Review of 80 consecutive cases of pediatric acute perforated appendicitis with intra-abdominal infection (IAI) medically managed with parenteral antibiotics and percutaneous drainage (PD) during a 7-year period. All patients received broad spectrum parenteral antibiotic therapy. One-third were hospitalized for >2 weeks. IAI was identified on admission in 60% compared with developing during hospitalization in 40% of cases. Before performing PD, the mean duration of antibiotic therapy in those who developed IAI during hospitalization was 6 days. IAI cultures yielded 127 bacterial isolates; polymicrobial infection occurred in 65% of cases. Only 7% of aspirates were sterile. The most common pathogens were Escherichia coli (82%), of which 5 isolates exhibited extended-spectrum β-lactamase production, and streptococci (40%). At the time of PD, 60% were febrile (mean duration of in-hospital fever, 7.5 days); 67% defervesced within 24 hours after the procedure. Posthospitalization abdominal complications (recurrent IAI or appendicitis) occurred in one-third of patients. Children with perforated appendicitis and IAI often have a complicated and prolonged clinical course. Medical management consisting solely of parenteral antibiotic therapy is frequently ineffective in resolving IAI. Rapid clinical improvement commonly follows PD.

    Aims To describe intra-abdominal pressures (IAP) generated during Pilates Mat and Reformer activities, and determine whether these activities generate IAP above a sit-to-stand threshold. Methods Twenty healthy women with no symptomatic vaginal bulge, median age 43 (range 22 – 59 years), completed Pilates Mat and Reformer exercise routines each consisting of 11 exercises. IAP was collected by an intra-vaginal pressure transducer, transmitted wirelessly to a base station, and analyzed for maximal and area under the curve (AUC) IAP. Results There were no statistically significant differences in mean max IAP between sit-to-stand and any of the Mat or Reformer exercises in the study population. Six to twenty-five percent of participants exceeded their individual mean max IAP sit-to-stand thresholds for 10 of the 22 exercises. When measuring AUC from 0 cm H2O, half the exercises exceeded the mean AUC of sit-to-stand but only Pilates Reformer and Mat roll-ups exceeded the mean AUC of sit-to-stand when calculated from a threshold of 40 cm H2O (consistent with, for example, walking). Conclusion Our results support recommending this series of introductory Pilates exercises including five Mat exercises and six Reformer exercises to women desiring a low IAP exercise routine. More research is needed to determine the long term effects of Pilates exercise on post-surgical exercise rehabilitation and pelvic floor health. PMID:25672647

    Objective To evaluate the efficacy of methylene blue in preventing recurrent symptomatic postoperative adhesions. Methods Patients with a history of >2 surgeries for intra-abdominal adhesion-related complications were selected for this study. Adhesiolysis surgery was subsequently performed using administration of 1% methylene blue. The follow-up period was 28.5 ± 11.1 months. Results Data were available from 20 patients (seven men and 13 women) whose mean ± SD age was 51.2 ± 11.4 years. Adhesions took longer to become symptomatic after the first abdominal surgery when the initial pathology was malignant compared with benign. However, the recurrence of adhesions after a previous adhesiolysis surgery had a similar time onset regardless of the initial disease. Following adhesiolysis surgery with methylene blue, the majority of patients did not present with symptoms associated with adhesion complications (i.e., chronic abdominal pain, bowel obstruction) for the length of the follow-up period. Conclusions The use of methylene blue during adhesiolysis surgery appears to reduce the recurrence of adhesion-related symptoms, suggesting a beneficial effect in the prevention of adhesion formation.

    2014-01-01

    Full Text Available Introduction. Enterovesical fistula is rare and is often caused by bowel inflammatory diseases and tumours in the urinary bladder or the intestine with local infiltration of bowel or bladder, respectively. The fistula usually presents with lower urinary tract symptoms, pneumaturia, and faecaluria or with food particles in the urine. Intra-abdominal retained surgical foreign bodies have also been reported as causes. Case Presentation. A case of atypical presentation in a woman with enterovesical fistula following abdominal hysterectomy. Investigations confirmed the presence of surgical towel in the urinary bladder and a pair of artery forceps in the abdomen. The towel was removed at cystoscopy after which she presented with food particles in the urine. She later had laparatomy to remove the haemostat and to repair the fistula. Discussion. A typical presentation of enterovesical fistula delayed the diagnosis and treatment in this patient. Conclusion. Managing patients with recurrent urinary tract infection after abdominal operation should include appropriate imaging of the abdomen with emphasis on pelvic organs. Also, surgical operation should always be given the best shot the first time and strict operation room standards and guidelines should always be followed.

    Applying appropriate positive end-expiratory pressure (PEEP) to corresponding intra-abdominal pressure (IAP) can improve gas exchange during capnoperitoneum without any hemodynamic effects. A total of 75 patients were randomly allocated to group 0PEEP (n=25), group 5PEEP (n=25), and group 10PEEP (n=25) according to the level of PEEP, in whom capnoperitoneum was created with IAP of 14, 8, and 14 mm Hg, respectively. Hemodynamic and respiratory parameters were recorded up to 30 minutes after capnoperitoneum. In 0PEEP group, mean end-tidal carbon dioxide demonstrated significant rise 2 minutes after capnoperitoneum and plateaued at about 15 minutes but remained at high level for up to 30 minutes when compared with the 5PEEP and 10PEEP groups (Phigher at 30 minutes when compared with 5PEEP (37.8±2.7 mm Hg) and 10PEEP (37.2±3.9 mm Hg) groups. The oxygenation was better preserved in 5PEEP and 10PEEP groups with significantly higher PaO2/Fio2 ratio. Heart rate, mean arterial pressure, and cardiac output remained stable throughout the study in all the 3 groups. Application of appropriate PEEP corresponding to the IAP helped maintain CO2 elimination and improved oxygenation without any hemodynamic disturbance in patients undergoing laparoscopic cholecystectomy.

    Full Text Available Amebiasis is quite uncommon in developed countries. Its clinical presentation can vary from an asymptomatic carrier state to fulminant colitis and colonic perforation. We presented a 39-year-old female who received combined chemotherapy and radiotherapy for nasopharyngeal carcinoma 1 year prior to admission. Thereafter, she felt acute abdominal pain and diarrhea after traveling to Hainan 3 months ago. A physical examination of the patient revealed diffused peritoneal sign. Abdominal computed tomography showed a cecal tumor and intra-abdominal abscess. A subsequent exploratory laparotomy revealed an infiltrating yellowish tumor about 7 cm over the cecum and massive serous ascites. Pathology reported ambeic colitis with undermined ulcer and abscess formation of the cecum. Ameboma can be found in developed countries, particularly in patients with risk factors and a history of traveling to areas with the developing disease. Colonoscopy with biopsy is recommended for patients with suspected ameboma, and surgical intervention is likely indicated in complicated cases although the surgical mortality rate is high.

    Full Text Available A 45-year-old woman was found to have a pancreatic tumor by abdominal ultrasound performed for a medical check-up. Abdominal contrast-enhanced computed tomography showed a hypovascular tumor measuring 30 mm in diameter in the pancreatic tail. Endoscopic ultrasound-guided fine needle aspiration was performed. An extragastric growing gastrointestinal stromal tumor was thereby diagnosed preoperatively, and surgical resection was planned. Laparoscopic surgery was attempted but conversion to open surgery was necessitated by extensive adhesions, and distal pancreatectomy, splenectomy, and partial gastrectomy were performed. The histological diagnosis was an intra-abdominal desmoid tumor. A desmoid tumor is a fibrous soft tissue tumor arising in the fascia and musculoaponeurotic tissues. It usually occurs in the extremities and abdominal wall, and only rarely in the abdominal cavity. We experienced a case with an intra-abdominal desmoid tumor that was histologically diagnosed after laparotomy, which had been preoperatively diagnosed as an extragastric growing gastrointestinal stromal tumor. Although rare, desmoid tumors should be considered in the differential diagnosis of intra-abdominal tumors. Herein, we report this case with a literature review.

    Acute appendicitis, especially if perforated at presentation, is often complicated by postoperative abscess formation. The detection of a postoperative abscess relies primarily on imaging. This has traditionally been done with contrast-enhanced computed tomography. Non-contrast magnetic resonance imaging (MRI) has the potential to accurately detect intra-abdominal abscesses, especially with the use of diffusion-weighted imaging (DWI). To evaluate our single-center experience with a rapid non-contrast MRI protocol evaluating post-appendectomy abscesses in children with persistent postsurgical symptoms. In this retrospective, institutional review board-approved study, all patients underwent a clinically indicated non-contrast 1.5- or 3-Tesla abdomen/pelvis MRI consisting of single-shot fast spin echo, inversion recovery and DWI sequences. All MRI studies were reviewed by two blinded pediatric radiologists to identify the presence of a drainable fluid collection. Each fluid collection was further characterized as accessible or not accessible for percutaneous or transrectal drainage. Imaging findings were compared to clinical outcome. Seven of the 15 patients had a clinically significant fluid collection, and 5 of these patients were treated with percutaneous drain placement or exploratory laparotomy. The other patients had a phlegmon or a clinically insignificant fluid collection and were discharged home within 48 h. Rapid non-contrast MRI utilizing fluid-sensitive and DWI sequences can be used to identify drainable fluid collections in post-appendectomy patients. This protocol can be used to triage patients between conservative management vs. abscess drainage without oral/intravenous contrast or exposure to ionizing radiation. (orig.)

    Although severely burned patients are at a high risk of developing intra-abdominal hypertension (IAH: IAP>12 mmHg) and Abdominal Compartment Syndrome (ACS) (IAP ≥ 20 mmHg), few data about its incidence and prevalence is available. Our aim was to determine the incidence and prevalence of IAH and ACS in patients with severe burns in our geographical setting. A pilot prospective, observational study was performed at the Burns Unit of the Plastic Surgery Department in Vall d'Hebron University Hospital (Barcelona), during a 12-month period. All patients with age ≥ 18 years old and burns >20% of the total body surface area (TBSA) were considered for inclusion. Patients who did not require urinary catheterization via the urethra were excluded. All patients included were followed during the first five days from their admission. Results are expressed as median (interquartile range) or frequency (percentage). During the study period, 303 patients were admitted to the Burns Unit. Twenty-five patients were included in the study (21 [84%] male, 4 [16%] female; age 42 [30-69 years]; TBSA burned 33 [25-58]%; all patients presented deep second-degree and/or third-degree burns). Eighteen (72%) patients met criteria for IAH, but only one (4%) developed ACS. The incidence of IAH and ACS was 0.56 and 0.04 cases/patient-day, respectively. Patients with IAH presented higher number of organs failure (2 [0-2.2] vs 0 [0-0]; p = 0.03). Patients with >20% TBSA burned presented a very high prevalence of IAH. Development of organ failure occurred even at moderately increased values of IAP. In this scenario, monitoring of IAP is the first step for establishing the importance of IAH/ACS in this patient population. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

  3. Intra-abdominal fat. Part I. The images of the adipose tissue localized beyond organs

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

    To determine the accuracy of complaints of abdominal pain and findings of abdominal tenderness for identifying children with intra-abdominal injury (IAI) stratified by Glasgow Coma Scale (GCS) score. This was a prospective, multicenter observational study of children with blunt torso trauma and a GCS score ≥13. We calculated the sensitivity of abdominal findings for IAI with 95% CI stratified by GCS score. We examined the association of isolated abdominal pain or tenderness with IAI and that undergoing acute intervention (therapeutic laparotomy, angiographic embolization, blood transfusion, or ≥2 nights of intravenous fluid therapy). Among the 12 044 patients evaluated, 11 277 (94%) had a GCS score of ≥13 and were included in this analysis. Sensitivity of abdominal pain for IAI was 79% (95% CI, 76%-83%) for patients with a GCS score of 15, 51% (95% CI, 37%-65%) for patients with a GCS score of 14, and 32% (95% CI, 14%-55%) for patients with a GCS score of 13. Sensitivity of abdominal tenderness for IAI also decreased with decreasing GCS score: 79% (95% CI, 75%-82%) for a GCS score of 15, 57% (95% CI, 42%-70%) for a GCS score of 14, and 37% (95% CI, 19%-58%) for a GCS score of 13. Among patients with isolated abdominal pain and/or tenderness, the rate of IAI was 8% (95% CI, 6%-9%) and the rate of IAI undergoing acute intervention was 1% (95% CI, 1%-2%). The sensitivity of abdominal findings for IAI decreases as GCS score decreases. Although abdominal computed tomography is not mandatory, the risk of IAI is sufficiently high that diagnostic evaluation is warranted in children with isolated abdominal pain or tenderness.

    Full Text Available Abstract Background Acute pancreatitis leads to abdominal hypertension and compartment syndrome. Weeks after the episodes pancreatic fluids sometimes organize to pseudocysts, fluid collections by or in the gland. Aims of the present study were to evaluate the intra-abdominal pressure (IAP induced by large pancreatic pseudocysts and to examine the effect of their transcutaneous drainage on IAP. Methods Twenty seven patients with a pancreatic pseudocyst were included. Nine patients with pseudocysts greater than 1l (group A had CT drainage and eighteen (volume less than 1l were the control group. The measurements of group A were taken 6 hours before and every morning after the drainage, while for group B, two measurements were performed, one at the day of the initial CT and one 7 days after. Abdominal compliance (Cabd was calculated. Data were analyzed using student's t-test. Results Baseline IAP for group A was 9.3 mmHg (S.D. 1.7 mmHg, while the first post-drainage day (PDD IAP was 5.1 mmHg (S.D. 0.7 mmHg. The second PDD IAP was 5.6 mmHg (S.D. 0.8 mmHg, the third 6.4 mmH (S.D. 1.2 mmHgg, the fourth 6.9 mmHg (S.D. 1.6 mmHg, the fifth 7.9 mmHg (S.D. 1.5 mmHg, the sixth 8.2 mmHg (S.D. 1.4 mmHg, and the seventh 8.2 mmHg (S.D. 1.5 mmHg. Group B had baseline IAP 8.0 mmHg (S.D. 1.2 mmHg and final 8.2 mmHg (S.D. 1.4 mmHg. Cabd after drainage was 185.6 ml/mmHg (SD 47.5 ml/mmHg. IAP values were reduced between the baseline and all the post-drainage measurements in group A. IAPs seem to stabilize after the 5th post-drainage day. Baseline IAP was higher in group A than in group B, while the two values, at day 7, were equivalent. Conclusion The drainage of large pancreatic pseudocyst reduces IAP. Moreover, the IAP seems to rise shortly after the drainage again, but in a way that it remains inferior to the initial value. More chronic changes to the IAP are related to abdominal cavity's properties and have to be further studied.

    Only limited pharmacokinetic data are available for anidulafungin in ICU patients, especially in patients treated for severe intra-abdominal infection (IAI). This was a prospective multicentre observational study in ICU patients with suspected yeast IAI. All patients received an intravenous loading dose of 200 mg of anidulafungin, followed by 100 mg/day. Thirteen blood samples were drawn between day 1 and day 5 for pharmacokinetic analysis. Samples were analysed by an HPLC-tandem MS method. Demographics and SAPS2 and SOFA scores were recorded. Fourteen patients with a median age (IQR) of 62 years (48-70) and with a mean BMI of 30.5 kg/m 2 were included from three centres; 57.1% were women. Their median (IQR) SAPS2 score was 54 (45-67) and their median (IQR) SOFA score was 8 (7-12). Six patients with community-acquired IAI and eight patients with nosocomial-acquired IAI were included. Twelve yeasts were isolated: six Candida albicans , two Candida glabrata , two Candida tropicalis , one Candida parapsilosis and one Candida krusei . Pharmacokinetic parameters were as follows [mean (% coefficient of variation)]: C max (mg/L) = 6.0 (29%); T max (h) = 1.6 (25.8%); C min (mg/L) = 3.2 (36.8%); AUC 0-24 (mg·h/L) = 88.9 (38.6%); t 1/2 (h) = 42.1 (68.2%); CL (L/h) = 1.2 (42.3%); and V (L) = 72.8 (87.8%). A two-compartment model best described the anidulafungin concentrations in the population pharmacokinetic study. The pharmacokinetic parameters of anidulafungin in critically ill ICU patients with complicated IAI are similar to those observed in the literature. However, an increased V and a longer t 1/2 were observed in this study. (EudraCT No. 2010-018695-25). © The Author 2017.

    Full Text Available 【Abstract】Objective: An accurate scoring system for intra-abdominal injury (IAI based on clinical manifestation and examination may decrease unnecessary CT scans, save time, and reduce healthcare cost. This study is designed to provide a new scoring system for a better diagno- sis of IAI after blunt trauma. Methods: This prospective observational study was performed from April 2011 to October 2012 on patients aged above 18 years and suspected with blunt abdominal trauma (BAT admitted to the emergency department (ED of Imam Hussein Hospital and Shohadaye Hafte Tir Hospital. All patients were assessed and treated based on Advanced Trauma Life Support and ED protocol. Diagnosis was done according to CT scan findings, which was considered as the gold standard. Data were gathered based on patient's history, physical exam, ultrasound and CT scan findings by a general practitioner who was not blind to this study. Chisquare test and logistic regression were done. Factors with significant relationship with CT scan were imported in multivariate regression models, where a coefficient (β was given based on the contribution of each of them. Scoring system was developed based on the obtained total βof each factor. Results: Altogether 261 patients (80.1% male were enrolled (48 cases of IAI. A 24-point blunt abdominal trauma scoring system (BATSS was developed. Patients were divided into three groups including low (score<8, moderate (8≤score<12 and high risk (score≥12. In high risk group immediate laparotomy should be done, moderate group needs further assessments, and low risk group should be kept under observation. Low risk patients did not show positive CT-scans (specificity 100%. Conversely, all high risk patients had positive CT-scan findings (sensitivity 100%. The receiver operating characteristic curve indicated a close relationship between the results of CT scan and BATSS (sensitivity=99.3%. Conclusion: The present scoring system furnishes a

    Full Text Available Context: Bacterial isolates from intra-abdominal infections, in particular, peritonitis and their unpredictable antimicrobial resistance patterns, continue to be a matter of concern not only globally but regionally too. Aim: An attempt in the present study was made to study the patterns of drug resistance in bacterial isolates, especially gram negative bacilli in intra-abdominal infections (IAI in our hospital. Materials and Methods: From 100 cases of peritonitis, identification of isolates was done as per recommended methods. Antimicrobial susceptibility and extended-spectrum beta-lactamase (ESBL testing were performed following the CLSI guidelines. Results: A total of 133 clinical isolates were obtained, of which 108 were aerobes and 22 anaerobes. Fungal isolates were recovered in only three cases. Escherichia coli (47/108 emerged as the most predominant pathogen followed by Klebsiella spp. (27/108, while Bacteroides fragilis emerged as the predominant anaerobe (12/22. Among coliforms, 61.7% E. coli and 74.1% Klebsiella spp. were ESBL positive. A high level of resistance was observed for beta lactams, ciprofloxacin, amikacin, and ertapenem. Ertapenem resistance (30-41% seen in coliforms, appears as an important issue. Imipenem, tigecycline, and colistin were the most consistently active agents tested against ESBL producers. Conclusion: Drug resistance continues to be a major concern in isolates from intra-abdominal infections. Treatment with appropriate antibiotics preceded by antimicrobial resistance testing aided by early diagnosis, adequate surgical management, and knowledge of antibiotic - resistant organisms appears effective in reducing morbidity and mortality in IAI cases.

    Full Text Available Marion J Skalweit1,2 1Department of Medicine, 2Department of Biochemistry, Louis Stokes Cleveland Department of Veterans Affairs and Case Western Reserve University School of Medicine, Cleveland, OH, USA Abstract: Drug-resistant pathogens have gained a foothold especially in the most vulnerable patient populations, hospitalized and immunocompromised individuals. Furthermore, extended-spectrum β-lactamase and carbapenemase-producing organisms are finding their way even into the community, with patients presenting to the hospital with established colonization and infection with resistant Enterobacteriaceae in particular. Recently, a novel antipseudomonal cephalosporin in combination with an established Class A β-lactamase inhibitor, ceftolozane/tazobactam has been approved by the FDA for use in the treatment of complicated urinary tract infections and complicated intra-abdominal infections. Ceftolozane is a uniquely potent antipseudomonal cephalosporin because of its high affinity for the penicillin-binding proteins of Pseudomonas aeruginosa, its low affinity for the intrinsic Class C β-lactamases of P. aeruginosa, its ability to enter P. aeruginosa through the outer membrane without the utilization of OprD protein, and the fact that it is not a substrate of the often upregulated MexAB/OprM efflux system of P. aeruginosa. The biological chemistry, pharmacokinetics/pharmacodynamics, microbiologic spectrum, and clinical trials that led to the approval of ceftolozane is reviewed. A discussion regarding its potential role in the treatment of complicated intra-abdominal infections and other infectious disease syndromes associated with drug-resistant pathogens follows.

    Bochdalek hernia (BH) is the most common type of congenital diaphragm hernia and is rarely seen in adults. In adult patients, BH often remains asymptomatic or presents with nondiagnostic symptoms and may lead to complications, though rarely. The necrosis and perforations occurring in the hernia may lead to mortality. In this report, we present a 34-year-old pregnant woman at 24 gestational weeks who presented with Bochdalek hernia causing gastric volvulus associated with perforation and intra-abdominal hemorrhage associated with splenic rupture.

    Intra-abdominal hypertension (IAH) is a recognized prognostic marker for severity of severe acute pancreatitis (SAP) and has a strong impact on the clinical course of SAP. Previous studies indicate that a Da-Cheng-Qi Decoction (DCQD) is beneficial in the treatment of SAP. The purpose of this study was to evaluate the effect of modified DCQD on IAH in patients with SAP. Between January 2008 and December 2008, 42 patients from the West China Hospital were randomized into either the DCQD or control group (n = 21 in each group). Mortality, intra-abdominal pressure (IAP), Acute Physiology and Chronic Health Evaluation II (APACHE II) score, C-reactive protein (CRP), oxygenation index, Balthazar CT score, rate of renal failure, decompression rate, intensive care unit (ICU) transfer rate, and length of hospital stay (LOS) were compared between the two groups. Compared to the control group, the modified DCQD treatment significantly decreased IAP (P < 0.05) and APACHE II (P < 0.05) scores on days 4 - 8, CRP on day 8 (P < 0.01), renal failure rate (P < 0.05), and LOS (P < 0.05). The oxygenation index was significantly improved in the DCQD group compared with the control group (P < 0.05). No significant differences in the Balthazar CT score, shock rate, ICU transfer rate, or mortality occurred between the two groups. The modified DCQD can effectively relieve IAH and decrease LOS for patients with SAP. Larger clinical trials are needed to confirm these findings.

    Pelvic inflammatory disease (PID) is frequent in adolescents and younger women. Diagnosis is usually based on the clinical findings, and the threshold for empiric antibiotic therapy should be low. However, at least in cases of resistance toward therapy or deterioration of symptoms, laparoscopic evaluation can be helpful. We searched the hospital charts for in-house patients who were treated for PID or tubo-ovarian abscess between 2007 and 2010. In cases with both vaginal and intra-abdominal bacterial cultures, results of those were compared. 73 patients with suspected PID or tubo-ovarian abscess were included. Median patients' age was 40 years (18-88), 18 of 73 (24.7 %) patients had an IUD at the time of consultation. 58 patients underwent laparoscopy or laparotomy. In 41 patients (70.7 %) tubo-ovarian abscess could be confirmed, four patients had differential gynecologic diagnoses, and two patients appendicitis. In vaginal swabs, most frequent bacteria were Streptococcus sp. (28.5 %), Escherichia coli (22.2 %), Enterococcus faecalis (15.9 %), and Staphylococcus sp. (9.5 %). In eight patients (11 %) Chlamydia trachomatis could be found, there was no case of Neisseria gonorrhea. In 33 patients both vaginal and abdominal cultures were available. In nine cases (27.3 %), identical bacteria could be found, however, 11 cases (33.3 %) showed different results. In severe cases of PID, laparoscopic evaluation and taking an intra-abdominal bacterial culture are helpful for the confirmation of diagnosis, accurate microbiologic testing and specific therapy.

    As space exploration is directed towards destinations beyond low-Earth orbit, the consequent new set of medical risks will drive requirements for new capabilities and more resources to ensure crew health. The Space Medicine Exploration Medical Conditions List (SMEMCL), developed by the Exploration Medical Capability element of the Human Research Program, addresses the risk of "unacceptable health and mission outcomes due to limitations of in-flight medical capabilities". It itemizes 85 evidence-based clinical requirements for eight different mission profiles and identifies conditions warranting further research and technology development. Each condition is given a clinical priority for each mission profile. Four conditions -- intra-abdominal infections, skin lacerations, anaphylaxis, and behavioral emergencies -- were selected as a starting point for analysis. A systematic literature review was performed to understand how these conditions are treated in austere, limited-resource, space-analog environments (i.e., high-altitude and mountain environments, submarines, military deployments, Antarctica, isolated wilderness environments, in-flight environments, and remote, resource-poor, rural environments). These environments serve as analogs to spaceflight because of their shared characteristics (limited medical resources, delay in communication, confined living quarters, difficulty with resupply, variable time to evacuation). Treatment of these four medical conditions in austere environments provides insight into medical equipment and training requirements for exploration-class missions.

    Today self-expanding polymers are considered as the most promising as means for intracavitary hemostasis in case of continuing bleeding after trauma. Testing of domestic open-cell polyurethane foam composition "Locus" was carried out on the developed experimental model simulating liver trauma of V degree. After damaging 6 experimental rabbits were injected intraperitoneally with 80 ml of the composition. 5 experimental rabbits were included into to control group (haemostatic agent was not given). Estimated blood loss was 111-124 ml. The two-hour survival rate didn't differ significantly: 3 animals survived in the experimental group; 2 animal survived in the control. Despite the 3-4-fold widening of the foam, due to open cells it absorbed 72.6 +/- 8.3 g of blood. Thus, open-cell polyurethane foam intraperitoneal administration of the composition didn't provide a temporary intra-abdominal hemostasis in liver. In order to enhance the hemostatic effect it requires changing the formulation of the polyurethane composition. For a more accurate assessment of the results it is neccessary to perform additional researches on larger animals.

    Preoperative risk stratification is a critical element in assessing the risks and benefits of surgery. Prior work has demonstrated that intra-abdominal general surgery patients can be classified based on their comorbidities and risk factors using latent class analysis (LCA), a model-based clustering technique designed to find groups of patients that are similar with respect to characteristics entered into the model. Moreover, the latent risk classes were predictive of 30-day mortality. We evaluated the use of latent risk classes to predict the risk of major postoperative complications. An observational, retrospective cohort of patients undergoing intra-abdominal general surgery in the 2005 to 2010 American College of Surgeons National Surgical Quality Improvement Program was obtained. Known preoperative comorbidity and risk factor data were entered into LCA models to identify the latent risk classes. Complications were defined as: acute kidney injury, acute respiratory failure, cardiac arrest, deep vein thrombosis, myocardial infarction, organ space infection, pneumonia, postoperative bleeding, pulmonary embolism, sepsis/septic shock, stroke, unplanned reintubation, and/or wound dehiscence. Relative risk regression determined the associations between the latent classes and the 30-day complication risks, with adjustments for the surgical procedure. The area under the curve (AUC) of the receiver operator characteristic curve assessed model performance. LCA fit a 9-class model on 466,177 observations. The composite complication risk was 18.4% but varied from 7.7% in the lowest risk class to 56.7% in the highest risk class. After adjusting for procedure, the latent risk classes were significantly associated with complications, with risk ratios (95% confidence intervals) (compared to the class with the average risk) varying from 0.56 (0.54-0.58) in the lowest risk class to 2.15 (2.11-2.20) in the highest risk class, a 4-fold difference.

    Ethnic differences in cardiometabolic risk (CMR) may be related to patterns of ethnic-specific body fat distribution. We aimed to identify differences across ethnic groups in interrelations between BMI, abdominal adiposity, liver fat, and CMR profile. In the International Study of Prediction of Intra-Abdominal Adiposity and Its Relationship With Cardiometabolic Risk/Intra-Abdominal Adiposity, 297 physicians recruited 4504 patients (from 29 countries). In the current cross-sectional analyses, 2011 whites, 166 African Caribbean blacks, 381 Hispanics, 1192 East Asians, and 347 Southeast Asians were included. Computed tomography was used to assess abdominal fat distribution and to estimate liver fat content. Anthropometric variables and CMR profile were measured. Higher ranges of BMI were associated with higher levels of visceral [visceral adipose tissue (VAT)] and deep subcutaneous [deep subcutaneous adipose tissue (DSAT)] adiposity, with significant ethnic differences regarding the slope of these relations. Despite lower absolute BMI values, East Asians presented the largest accumulation of VAT but the lowest accumulation of DSAT with increasing adiposity. The association of BMI with liver fat did not differ between ethnic groups. Liver fat and DSAT were positively correlated with VAT with no ethnic variation. All ethnic groups had a similar association between a 1-SD increase in VAT, DSAT, or liver fat with hypertension, type 2 diabetes, hypertriglyceridemia, low HDL-cholesterol concentration, or high C-reactive protein concentration. Ethnicity significantly affects abdominal adiposity and liver fat partitioning, and East Asians have the most deleterious abdominal fat distribution. Irrespective of ethnicity, abdominal and hepatic fat depots are strongly interrelated and increased with obesity. Higher amounts of VAT or liver fat are associated with a more deteriorated CMR profile in all ethnic groups.

    A 2.5-year-old, female opossum had acute stranguria. Based on radiography and ultrasonographic examination a cystic structure was identified in the caudal abdomen associated with bilateral hydroureter and hydronephrosis. This structure contained a neutrophilic fluid, determined to be urine. There was a neutrophilic leukocytosis. Serum chemistry values were within normal limits. The opossum was euthanized. An intra-abdominal fat pad incarceration of the urinary bladder above the trigone was present, resulting in complete obstruction of the urinary bladder and partial obstruction of the ureters. Vessels to the bladder were involved in the incarceration which resulted in vascular compromise and infarction of the bladder. Mild to moderate hydroureter and hydronephrosis were present.

    Full Text Available Objectives: Resistin, a hormone secreted from adipocytes and considered to be a likely cause of insulin resistance, has recently been accepted as a proinflammatory cytokine. This study aimed to determine the correlation between resistin levels in patients with intra-abdominal sepsis and mortality. Methods: Of 45 patients with intraabdominal sepsis, a total of 35 adult patients were included in the study. This study was undertaken from December 2011 to December 2012 and included patients who had no history of diabetes mellitus and who were admitted to the general surgery intensive care units of Gazi University and Bülent Ecevit University School of Medicine, Turkey. Evaluations were performed on 12 patients with sepsis, 10 patients with severe sepsis, 13 patients with septic shock and 15 healthy controls. The patients’ plasma resistin, interleukin-6 (IL-6, tumour necrosis factor alpha (TNF-α, interleukin-1 beta (IL-1β, procalcitonin, lactate and glucose levels and Acute Physiology and Chronic Health Evaluation (APACHE II scores were studied daily for the first five days after admission. A correlation analysis of serum resistin levels with cytokine levels and APACHE II scores was performed. Results: Serum resistin levels in patients with sepsis were significantly higher than in the healthy controls (P <0.001. A significant correlation was found between serum resistin levels and APACHE II scores, serum IL-6, IL-1β, TNF-α, procalcitonin, lactate and glucose levels. Furthermore, a significant correlation was found between serum resistin levels and all-cause mortality (P = 0.02. Conclusion: The levels of resistin were significantly positively correlated with the severity of disease and were a possible mediator of a prolonged inflammatory state in patients with intra-abdominal sepsis.

    Full Text Available This study aims to investigate the association between body mass index (BMI or intra-abdominal fat measured by computed tomography (CT and bowel symptoms.A cohort of 958 Japanese adults who underwent colonoscopy and CT and completed questionnaires after excluding colorectal diseases was analyzed. Six symptoms (constipation, diarrhea, loose stools, hard stools, fecal urgency, and incomplete evacuation using a 7-point Likert scale were evaluated between baseline and second questionnaire for test-retest reliability. Associations between BMI, visceral adipose tissue (VAT, subcutaneous adipose tissue (SAT, and symptom score were analyzed by a rank-ordered logistic model, adjusting for age, sex, smoking, and alcohol consumption, hypertension, diabetes mellitus, and dyslipidemia.Some bowel symptom scores were significantly (p<0.05 different between the age groups, sexes, smoking, and alcohol consumption. In multivariate analysis, constipation was associated with low BMI (p<0.01, low VAT area (p = 0.01, and low SAT area (p<0.01. Moreover, hard stools was associated with low BMI (p<0.01 and low SAT area (p<0.01. The remaining symptoms were not significantly associated with BMI or intra-abdominal fat. Test-retest reliability of bowel symptom scores with a mean duration of 7.5 months was good (mean kappa, 0.672.Both low BMI and low abdominal fat accumulation appears to be useful indicators of increased risk for constipation and hard stools. The long-term test-retest reliability of symptom score suggests that bowel symptoms relevant to BMI or visceral fat remain consistent over several months.

Method A cohort of 958 Japanese adults who underwent colonoscopy and CT and completed questionnaires after excluding colorectal diseases was analyzed. Six symptoms (constipation, diarrhea, loose stools, hard stools, fecal urgency, and incomplete evacuation) using a 7-point Likert scale were evaluated between baseline and second questionnaire for test-retest reliability. Associations between BMI, visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), and symptom score were analyzed by a rank-ordered logistic model, adjusting for age, sex, smoking, and alcohol consumption, hypertension, diabetes mellitus, and dyslipidemia. Results Some bowel symptom scores were significantly (p<0.05) different between the age groups, sexes, smoking, and alcohol consumption. In multivariate analysis, constipation was associated with low BMI (p<0.01), low VAT area (p = 0.01), and low SAT area (p<0.01). Moreover, hard stools was associated with low BMI (p<0.01) and low SAT area (p<0.01). The remaining symptoms were not significantly associated with BMI or intra-abdominal fat. Test-retest reliability of bowel symptom scores with a mean duration of 7.5 months was good (mean kappa, 0.672). Conclusions Both low BMI and low abdominal fat accumulation appears to be useful indicators of increased risk for constipation and hard stools. The long-term test-retest reliability of symptom score suggests that bowel symptoms relevant to BMI or visceral fat remain consistent over several months. PMID:25906052

    Abscess formation associated with intra-abdominal sepsis causes severe morbidity and can be fatal. Previous studies have implicated T cells in the pathogenesis of abscess formation, and we have recently shown that CD4(+) T cells activated in vitro by zwitterionic capsular polysaccharides from abscess-inducing bacteria such as Staphylococcus aureus and Bacteroides fragilis initiate this host response when transferred to naive rats. In this study, we show that mice deficient in alphabetaTCR-bearing T cells or CD4(+) T cells fail to develop abscesses following challenge with B. fragilis or abscess-inducing zwitterionic polysaccharides, compared with CD8(-/-) or wild-type animals. Transfer of CD4(+) T cells from wild-type mice to alphabetaTCR(-/-) animals reconstituted this ability. The induction of abscesses required T cell costimulation via the CD28-B7 pathway, and T cell transfer experiments with STAT4(-/-) and STAT6(-/-) mice demonstrated that this host response is dependent on STAT4 signaling. Significantly higher levels of IL-17, a proinflammatory cytokine produced almost exclusively by activated CD4(+) T cells, were associated with abscess formation in Th2-impaired (STAT6(-/-)) mice, while STAT4(-/-) mice had significantly lower levels of this cytokine than control animals. The formation of abscesses was preceded by an increase in the number of activated CD4(+) T cells in the peritoneal cavity 24 h following bacterial challenge. Confocal laser-scanning microscopy analysis revealed that CD4(+) T cells comprise the abscess wall in these animals and produce IL-17 at this site. Administration of a neutralizing Ab specific for IL-17 prevented abscess formation following bacterial challenge in mice. These data delineate the specific T cell response necessary for the development of intra-abdominal abscesses and underscore the role of IL-17 in this disease process.

    Full Text Available INTRODUCTION: Intra-abdominal hypertension (IAH is known as a common, serious complication in critically ill patients. Bacterial translocation and permeability changes are considered the pathophysiological bases for IAH-induced enterogenic endotoxemia and subsequent multiorgan failure. Nevertheless, the effects of slightly elevated intra-abdominal pressures (IAPs on the intestinal mucosa and the associated mechanisms remain unclear. METHODS: To investigate the acute effects of different nitrogen pneumoperitoneum grades on colonic mucosa, male Sprague-Dawley rats were assigned to six groups with different IAPs (0 [control], 4, 8, 12, 16, and 20 mmHg, n = 6/group. During 90 min of exposure, we dynamically monitored the heart rate and noninvasive hemodynamic parameters. After gradual decompression, arterial blood gas analyses were conducted. Thereafter, structural injuries to the colonic mucosa were identified using light microscopy. Colon permeability was determined using the expression of tight junction proteins, combined with fluorescein isothiocyanate dextran (FD-4 absorption. The pro-oxidant-antioxidant balance was determined based on the levels of malondialdehyde (MDA and antioxidant enzymes. RESULTS: IAH significantly affected the histological scores of the colonic mucosa, tight junction protein expression, mucosal permeability, and pro-oxidant-antioxidant balance. Interestingly, elevations of IAP that were lower than the threshold for IAH also showed a similar, undesirable effect. In the 8 mmHg group, mild hyponatremia, hypocalcemia, and hypoxemia occurred, accompanied by reduced blood and abdominal perfusion pressures. Mild microscopic inflammatory infiltration and increased MDA levels were also detected. Moreover, an 8-mm Hg IAP markedly inhibited the expression of tight junction proteins, although no significant differences in FD-4 permeability were observed between the 0- and 8-mmHg groups. CONCLUSIONS: Acute exposure to slightly

    Intra-abdominal adhesions may result in an increased risk of major complications in case of a repeated cesarean section, such as bladder and bowel injury, hemorrhage, infection, and hysterectomy. In an attempt to predict intra-abdominal adhesions before a repeated cesarean delivery, we suggest the use of a novel technique employing a simple and feasible ultrasound imaging technique. The study included pregnant women who underwent one or more cesarean deliveries in their obstetric history and were evaluated during the third trimester of the ongoing pregnancy. In order to diagnose intra-abdominal adhesions, we used a sonographic sliding sign of the uterus under the inner part of the fascia of the abdominal muscles, and considered women 1) at high risk for severe adhesions in the absence of sonographic uterine sliding; or 2) at a low risk for severe adhesions in the presence of an obvious or moderate uterine sliding. A comparison between sonographic findings and intra-abdominal adhesions as evaluated by the surgeons during surgery was performed. We examined 63 patients with one or more previous cesarean delivery. Out of these 63 patients, 59 had completed the study and underwent repeated cesarean section at our Institution. In 16 out of the19 cases assigned to the high risk for severe adhesions group, the suspicion was confirmed at surgery, with a sensitivity of 76.2%. In addition, the suspicion for low risk for adhesions was confirmed in 35 out of 40 patients, with a specificity of 92.1%. The inter and intra-observer correlation using Cohen's Kappa (k) coefficient were 0.52 and 0.77 respectively. Our data show that a simple sonographic sign might predict both high and low risk for intra-abdominal adhesions in patients who underwent previous cesarean delivery. This technique may aid clinical decisions regarding repeated cesarean section approach. This article is protected by copyright. All rights reserved.

    To compare clinical and economic outcomes in patients with community-acquired intra-abdominal infection (IAI) due to extended spectrum beta-lactamase (ESBL) producing (ESBL-positive) bacteria versus non-ESBL-producing (ESBL-negative) bacteria in China. This was a retrospective chart review study of patients hospitalized with community-acquired IAI due to ESBL-positive or ESBL-negative infections caused by Escherichia coli or Klebsiella spp. Data were collected from six hospitals in China that participated in the Study for Monitoring Antibiotic Resistance Trends (SMART) during 2006-2007. Outcomes included clinical response at discharge and following first-line antibiotic, number of antibiotic agents and classes, duration of hospitalization, and overall hospitalization and intravenous antibiotic costs. Of the 85 patients included in the study, 32 (37.6%) had ESBL-positive and 53 (62.4%) had ESBL-negative infections; E. coli was responsible for 77.6% of infections. Infection resolved at discharge in 30 (93.8%) ESBL-positive and 48 (90.6%) ESBL-negative patients (P = NS). Fewer ESBL-positive patients achieved complete response following first-line antibiotics (56.3% versus 83.0%; P = 0.01). ESBL-positive patients required longer antibiotic treatment, more antibiotics, longer hospitalization (24.3 versus 14.6 days; 1.67-fold ratio; P = 0.001), and incurred higher hospitalization costs ( yen24,604 vs. yen13,788; $3604 vs. $2020; 1.78-fold ratio; P < 0.001). Patients with ESBL-positive infection had similar resolution rates at discharge compared to those with ESBL-negative infection, despite poorer first-line antibiotic response. However, ESBL-positive infection led to significantly greater hospitalization cost and intravenous antibiotic cost, and longer hospital stay.

    Full Text Available The primary and metastatic gastrointestinal synovial sarcoma is rare with a wide differential diagnosis. It usually expresses cytokeratins EMA, BCL2 with an occasional CD99, and S100 positivity but not desmin. We present a case of metastatic synovial sarcoma with unusual immunophenotype causing diagnostic challenges. The tumor cells showed focal cytokeratin, EMA, and, unexpectedly, desmin positivity. Additional intranuclear TLE-1 positivity and negativity for CD34 and DOG-1 were also identified. A diagnosis of monophasic synovial sarcoma was confirmed by using FISH break-apart probe. RT-PCR revealed the SYT-SSX1 fusion gene. Intra-abdominal synovial sarcoma, either primary or metastatic, with unusual desmin positivity raises the diagnostic challenge, since a wide range of differential diagnoses could show a similar immunophenotype (leiomyosarcoma, desmoid tumor, myofibroblastic tumor, and rarely GIST etc.. Typical morphology and focal cytokeratin/EMA positivity should alert to this tumor, and FISH and RT-PCR remain the gold standard for the confirmation.

    Damage control surgery (DCS) was developed to manage exsanguinating trauma patients, but is increasingly applied to the management of peritoneal sepsis and abdominal catastrophes. Few manuscripts compare the outcomes of these surgeries on disparate patient populations. A multi-institutional three group propensity score matched case cohort study comparing penetrating trauma (PT-DCS), blunt trauma (BT-DCS), and intraperitoneal sepsis (IPS-DCS) was performed comparing patients treated with DSC between 2008 and 2013. Propensity scoring was performed using demographic and presenting physiologic data. Four hundred and twelve patients were treated with DCS across two institutions. Propensity matching for age, gender, and initial Acute Physiology and Chronic Health Evaluation II score 80 identified 80 patients per group for comparison. Rate of primary fascial closure was lowest in the IPS-DCS group, and highest in the penetrating trauma DCS group. Intra-abdominal complication rates were highest in the IPS-DCS group. IPS-DCS had increased time to definitive closure compared with the other two groups (RR 1.8; 1.3-2.2; P eight days were more than twice the risk of death at 90 days across all groups. (RR 2.15; 1.2-3.5; P managed via DCS.

    Prosthetic mesh is used frequently in abdominal wall hernia reconstruction but is prone to postoperative adhesion formation. Complications resulting from intra-abdominal adhesions represent a considerable clinical and cost burden. We, herein, investigate the antiproliferative and antiadhesiogenic properties of sirolimus and hydrogel-impregnated, drug-eluting mesh to decrease such complications in a mouse model of abdominal wall hernia repair. A 1 × 1cm(2) polypropylene mesh from 1 of 3 groups (group 1, plain control; group 2, hydrogel [2% agarose]; and group 3, hydrogel + 10 mcg sirolimus) was implanted operatively into the peritoneal cavity of BALB/c mice and followed for up to 4 weeks. Adhesions were scored by percent surface area of mesh (range, 0-100%), severity (range, 0-3), and tenacity (range, 0-4). Representative samples were assessed by scanning electron microscopy. Mesh impregnated with the combination of hydrogel and sirolimus led to a significant decrease in adhesion formation. The percent surface area of adhesional attachment to mesh was decreased from 100.0 ± 0% in the plain mesh control group versus 18 ± 8% (P model, was well tolerated without side effects, and has potential for clinical application.

    Full Text Available Gastrointestinal stromal tumors (GISTs in adolescence are far less common than adult GISTs and have varied GIST genotypes that present diagnostic and therapeutic challenges. Here, we discuss a 21-year-old male with diagnosis of unresectable, imatinib-resistant GIST. At initial evaluation, a neoadjuvant treatment approach was recommended. As such, the patient received imatinib over the course of one year. Unfortunately, the GIST increased in size, and a subsequent attempt at surgical resection was aborted fearing infiltration of major vascular structures. The patient was then referred to our institution, at which time imatinib therapy was discontinued. Surgical intervention was again considered and the patient underwent successful resection of massive intra-abdominal GIST with total gastrectomy and Roux-en-Y esophagojejunostomy. Since pediatric GISTs are typically resistant to imatinib, we performed genotype analysis of the operative specimen that revealed KIT mutations associated with imatinib sensitivity and resistance. Given the sequencing data and operative findings, the patient was started postoperatively on sunitinib. This case illustrates the importance of understanding both adult and pediatric GISTs when implementing appropriate treatment regimens. Since the genotype of GISTs dictates phenotypic behavior, mutational analysis is an important component of care especially for adolescents whose disease may mirror the pediatric or adult population.

    Full Text Available We have previously shown that physical activity predicts intra-abdominal adipose tissue (IAT, but it is unknown whether energy intake predicts IAT independently of physical activity in a community-based, naturalistic environment. The association of energy intake with IAT was explored cross-sectionally in women, recruited between 2002 and 2005 for a study of fat patterning in midlife. IAT at L4-L5 vertebral interspace was assessed by computed tomography, energy intake by the Block Food Frequency Questionnaire, and physical activity by the Kaiser Physical Activity Survey. Linear regression models were used for the principal analyses. Among the 257 women, 48% were African American and 52% were Caucasian. Women were 52±3 years old, and 49% were postmenopausal. Every 500 kcal increase in energy intake was associated with a 6% higher IAT (P=0.02, independent of physical activity (P=0.02, after adjustment for ethnicity, menopausal status, age, smoking, income, and DXA-assessed percent body fat. Energy intake had a significant interaction with ethnicity (P=0.02, but not with physical activity. Models using the IAT to subcutaneous abdominal adipose tissue ratio as an outcome had similar associations. In conclusion, self-reported EI was associated with preferential IAT accumulation in midlife women, independent of physical activity. This association was significantly stronger in Caucasian than African American women. Future longitudinal studies are needed to explore lifestyle predictors of IAT accumulation during the menopausal transition.

    The aim of this study was to evaluate the impact of preoperative hypoalbuminemia on the development of intra-abdominal septic complications (IASCs) after primary anastomosis for patients with Crohn's disease (CD). All CD patients undergoing bowel resection with a primary anastomosis during the study period from 2007 to 2015 were enrolled. The association of preoperative hypoalbuminemia (preoperative albumin level. Preoperative hypoalbuminemia occurred in 13 (11.7%) patients. The duration from diagnosis to surgery was longer for patients with preoperative hypoalbuminemia than those without ( p = 0.012). Patients with preoperative hypoalbuminemia were more likely to have a history of preoperative use of 5-aminosalicylic acid ( p = 0.013) and have an intraoperative finding of small bowel obstruction ( p = 0.015). Of all patients, 24 (19.4%) developed postoperative IASCs. Univariate analysis showed that patients with preoperative hypoalbuminemia had an increased risk for IASCs ( p = 0.012). Multivariate analysis confirmed the association between preoperative hypoalbuminemia and IASCs (odds ratio 4.67, 95% confidence interval: 1.28-17.04, p = 0.02). Similar findings were also obtained when preoperative albumin level was analysed as a continuous variable ( p = 0.019). Preoperative hypoalbuminemia is a significant predictor for the development of postoperative IASCs in CD patients after bowel resection with a primary anastomosis. Favorable preoperative nutrition status might lessen the risk for IASCs.

    Severely burned patients have altered drug pharmacokinetics (PKs), but it is unclear how different they are from those in other critically ill patient groups. The aim of the present study was to compare the population pharmacokinetics of micafungin in the plasma and burn eschar of severely burned patients with those of micafungin in the plasma and peritoneal fluid of postsurgical critically ill patients with intra-abdominal infection. Fifteen burn patients were compared with 10 patients with intra-abdominal infection; all patients were treated with 100 to 150 mg/day of micafungin. Micafungin concentrations in serial blood, peritoneal fluid, and burn tissue samples were determined and were subjected to a population pharmacokinetic analysis. The probability of target attainment was calculated using area under the concentration-time curve from 0 to 24 h/MIC cutoffs of 285 for Candida parapsilosis and 3,000 for non-parapsilosis Candida spp. by Monte Carlo simulations. Twenty-five patients (18 males; median age, 50 years; age range, 38 to 67 years; median total body surface area burned, 50%; range of total body surface area burned, 35 to 65%) were included. A three-compartment model described the data, and only the rate constant for the drug distribution from the tissue fluid to the central compartment was statistically significantly different between the burn and intra-abdominal infection patients (0.47 ± 0.47 versus 0.15 ± 0.06 h−1, respectively; P burn patients and intra-abdominal infection patients. After the first dose, micafungin at 100 mg/day achieved the PK/PD targets in plasma for MIC values of ≤0.008 mg/liter and ≤0.064 mg/liter for non-parapsilosis Candida spp. and Candida parapsilosis species, respectively.

    Some patients with refractory peritoneal dialysis-related peritonitis continue to develop intra-abdominal complications despite removal of the peritoneal catheter. Repeated percutaneous drainage or open laparotomy is often required, and mortality is not uncommon. The benefits of pelvic drainage placement during catheter removal in decreasing these complications and interventions remain unproven. Forty-six patients with refractory peritonitis who underwent removal of a Tenckhoff catheter between 1991 and 2013 were reviewed retrospectively. Twelve patients had pelvic drainage using closed active suction devices during catheter removal (drainage group). The remaining 34 patients underwent catheter removal without drainage (non-drainage group). The outcomes measured were the development of intra-abdominal complications and the requirement for repeated percutaneous drainage or open laparotomy within 90 days after the catheter removal. Baseline characteristics were similar with the exception of a higher median number of previous peritonitis episodes in the drainage group compared with the non-drainage group (2 vs 0, P = 0.02). During the follow-up period, intra-abdominal complications occurred in 15 (44%) of 34 patients in the non-drainage group, compared with one (8%) of 12 patients in the drainage group (P = 0.03). Twelve (35%) patients in the non-drainage group required repeated percutaneous drainage or open laparotomy for management, compared with zero (0%) patients in the drainage group (P = 0.02). Drain tubes were removed at a median of 6 days (inter-quartile range: 5-10) without complications. In the management of refractory peritonitis, pelvic drainage during removal of dialysis catheter decreases the risk of subsequent intra-abdominal complications and invasive interventions. © 2015 Asian Pacific Society of Nephrology.

    Full Text Available The play has been shown to help children adjust to the school setting and to enhance children's learning [1]. Since this theory, the current study was designed to examine the significance of mechanical effects of intra-abdominal on posture/balance control among the Algerian Childhood Primary Schools. Since our teachers emphasise the good classroom settings as a discipline pedagogical aspect of success learning. While High-quality educational programs for children in preschool and kindergarten have play at the centre of the curriculum [2].

Based on the analysis statistics, we confirm: • Prolonged periods classroom settings increase Intra-Abdominal Fat which represents big risk posture/balance control. • Primary schools posture needs an interactive play method Learning classroom to improve body imbalance as health benefits physical activities. Based on the differences acquired by the research team, we emphasise that prolonged periods classroom settings Primary Schools increase the intra-abdominal which owing to the weakness of skeletal muscle fatigue and abnormal pathological alignment. While as a recommendation pedagogy practised, we suggested to our teachers, who work with these children to know that the balanced posture requires more energy in the class, Considering that our student seat more than 6 hours a day, 30 per week, and

  20. Increased intra-abdominal fat may lower HDL levels by increasing the fractional catabolic rate of Lp A-I in postmenopausal women.

    High-density lipoprotein (HDL) particles without apolipoprotein A-II (Lp A-I) may be more anti-atherogenic than HDL with apo A-II (Lp A-I/AII) and Lp A-I is reported selectively to be reduced in cases of intra-abdominal obesity. We explored the mechanisms of this reduction by studying the turnover of Lp A-I and Lp A-I/A-II in postmenopausal women well characterized for total body, regional and sub-regional adiposity by body mass index (BMI), truncal girth ratio, and abdominal magnetic resonance imaging (MRI), respectively. We tested for possible cause-effect relationships by measuring inter-correlations among these variables. Intra-abdominal fat area correlated strongly and positively with the fractional catabolic rate (FCR) of Lp A-I (r=0.98, P=0.003). Intra-abdominal fat only showed a non-significant trend toward correlation with the FCR of Lp A-I/A-II (r=0.84, P=0.07), and had no correlation with the production or transport rate (TR) of either Lp A-I or Lp A-I/A-II (r=0.48 and 0.02, respectively, P>0.1). Subjects were studied both with and without estrogen replacement, allowing exploration of a possible interaction of adiposity with estrogen effects on HDL turnover. Response of HDL turnover to estrogen did not correlate with adiposity, except for a parameter of waist to hip ratio (WHR), which predicted the increase in LP A-I TR with estrogen (r=0.84, P=0.04). We conclude that intra-abdominal fat may lower HDL levels by increasing the FCR of Lp A-I, suggesting a mechanism by which central adiposity may be proatherogenic.

    Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is the best operative treatment currently available for patients with peritoneal carcinomatosis of ovarian origin. The open abdomen technique is the classic technique for hyperthermic intraperitoneal chemotherapy. We developed a closed abdomen model that improves temperature control and increases exposure of peritoneal surfaces to the drug by recirculating the perfusate. We used a porcine model with 12 female, Large White pigs-4 in the open technique group and 8 in the closed technique CO2 group. We performed cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for 60 minutes using paclitaxel (175 mg/m(2)) at an input temperature of 42°C. Perfusate recirculation was performed under controlled pressure (range, 12-15 mmHg). The infusion of 0.7 L of CO2 via a separate intraperitoneal infusion catheter mixed the perfusate within the peritoneal cavity. Intra-abdominal temperature was assessed using 6 intra-abdominal temperature probes and 2 temperature probes in the inflow and outflow circuits. Drug distribution was assessed using methylene blue staining. Intra-abdominal temperatures remained constant and homogeneous in all intra-abdominal quadrants with a constant input temperature of 42°C and a minimum output temperature of 41.4°C. The infused CO2 caused the fluid to bubble and created agitation inside the abdominal cavity to facilitate a homogeneous distribution of the drug-containing perfusate. The closed recirculation hyperthermia with intraperitoneal chemotherapy technique developed in this study is safe and feasible, and may provide a more homogeneous delivery of heated chemotherapy to the peritoneal cavity in patients with peritoneal malignancies.

    Full Text Available Two case reports are used to illustrate the signs and symptoms, complications and treatments of chronic socket inflammation due to intraorbital implants. The ophthalmic examination, surgeries and treatments are documented. Two anophthalmic cases that underwent enucleation and multiple orbital surgeries to enhance the anophthalmic socket volume developed pain, intense discharge and contracted cavities with chronic inflammation in the socket which was nonresponsive to medical therapy. Computed tomography indicated a hypodense foreign body in both cases causing an intense inflammatory reaction. The implants were removed by excisional surgery and a room temperature vulcanized silicone implant was retrieved in both cases. Socket inflammation resolved in both cases after implant removal. An intraorbital inflammatory reaction against an intraorbital implant can cause chronic socket inflammation in patients with a history of multiple surgeries. Diagnosis requires imaging and the definitive treatment is implant removal.

    Full Text Available Abstract The CIAO Study is a multicenter observational study currently underway in 66 European medical institutions over the course of a six-month study period (January-June 2012. This preliminary report overviews the findings of the first half of the study, which includes all data from the first three months of the six-month study period. Patients with either community-acquired or healthcare-associated complicated intra-abdominal infections (IAIs were included in the study. 912 patients with a mean age of 54.4 years (range 4–98 were enrolled in the study during the first three-month period. 47.7% of the patients were women and 52.3% were men. Among these patients, 83.3% were affected by community-acquired IAIs while the remaining 16.7% presented with healthcare-associated infections. Intraperitoneal specimens were collected from 64.2% of the enrolled patients, and from these samples, 825 microorganisms were collectively identified. The overall mortality rate was 6.4% (58/912. According to univariate statistical analysis of the data, critical clinical condition of the patient upon hospital admission (defined by severe sepsis and septic shock as well as healthcare-associated infections, non-appendicular origin, generalized peritonitis, and serious comorbidities such as malignancy and severe cardiovascular disease were all significant risk factors for patient mortality. White Blood Cell counts (WBCs greater than 12,000 or less than 4,000 and core body temperatures exceeding 38°C or less than 36°C by the third post-operative day were statistically significant indicators of patient mortality.

    To investigate the role of increased intra-abdominal pressure (IAP) on the intratumoral accumulation and the antitumor effect of intraperitoneal cisplatin in rats with advanced peritoneal carcinomatosis. To evaluate the tolerance of IAP in pigs, as it is a large animal with a body size equivalent to humans. To investigate if an active convection, driven by a positive IAP, increases cisplatin penetration and antitumor effectiveness in a model of advanced peritoneal carcinomatosis in rats. BDIX rats with macroscopic peritoneal tumors received cisplatin administered as intravenous injection (IV), conventional intraperitoneal injection (IP), or sustained intraperitoneal injection of cisplatin given in a large volume of solvent for maintaining IAP for 1 hour. Platinum tissue concentration was measured by atomic absorption spectroscopy (AAS), and platinum distribution into the tumor nodules was assessed by the particular-induced x-ray emission (PIXE) method. The antitumor effect was assessed in a survival experiment. The hemodynamic, local, and systemic tolerance of IAP, with or without cisplatin, was evaluated in Large White pigs. The maximum tolerated IAP was 22 mm Hg for 1 hour in nonventilated rats. IAP, in comparison with IV or conventional IP injections, resulted in the increased concentration and depth of diffusion of platinum into diaphragm and peritoneal tumor nodules. Consequently, IAP treatment induced an extended survival of rats treated at an advanced stage of carcinomatosis. In 7 50- to 70-kg ventilated pigs, a 40-mm Hg IAP was well tolerated when maintained stable for 2 hours. Renal failure occurred in pigs receiving a total dose of 200 and 400 mg of cisplatin with IAP, but a dose of 100 mg was well tolerated. Intraperitoneal chemotherapy with increased IAP, in comparison with conventional IP or IV chemotherapy, improved the tumor accumulation and the antitumor effect of cisplatin in rats bearing advanced peritoneal carcinomatosis. In preclinical

    The aim of the study was to describe the characteristics of cirrhotic patients with candidemia and intra-abdominal candidiasis (IAC) and to evaluate the risk factors associated with 30-day mortality. A multicenter multinational retrospective study including all consecutive episodes of candidemia and IAC in adult patients with liver cirrhosis in 14 European hospitals during the period 2011-2013 was performed. A total of 241 episodes (169 candidemia, 72 IAC) were included. Most Candida infections were acquired in hospital (208, 86.3%), mainly in the intensive care unit (ICU) (121, 50.2%). At clinical presentation, fever was seen in 60.6% of episodes (146/241) and septic shock in 34.9% (84/241). C. albicans was the most common species (found in 131 episodes, 54.4%), followed by C. glabrata (35, 14.5%) and C. parapsilosis (34, 14.1%). Overall, the 30-day mortality was 35.3%. Multivariable analysis identified candidemia (OR 2.2, 95% CI 1.2-4.5) and septic shock (OR 3.2, 95% CI 1.7-6) as independent factors associated with 30-day mortality. Adequate antifungal treatment (OR 0.4, 95% CI 0.3-0.9) was associated with survival benefit. A shift towards increasing prevalence of C. glabrata and C. parapsilosis species in patients with liver disease was documented. Candidemia and IAC were associated with significant mortality in cirrhotic patients. Thirty-day mortality was associated with candidemia and severe clinical presentation, whereas adequate antifungal treatment improved the prognosis.

    A series of standardized tasks, isometric trunk flexion and extension and maximal Valsalva manoeuvres, were used to evaluate the role of the abdominal musculature in developing an increased intra-abdominal pressure (IAP). Seven male subjects were measured for IAP, myoelectric activity of rectus abdominis (RA), obliquus externus and internus (OE and OI respectively), erector spinae (ES) and isometric trunk torque. IAPs in all experimental conditions were markedly greater than those that occurred while relaxed. In isometric trunk flexion, IAPs were increased with accompanying high levels of activity from the abdominal muscles. In contrast, little activity from the abdominal muscles occurred during isometric trunk extension, although levels of IAP were similar to those found in the isometric flexion condition. With maximal voluntary pressurization (Valsalva manoeuvre) slightly higher levels of IAP than those found in torque conditions were recorded, this pressure being produced with abdominal activities (OE and OI) less than one fourth their recorded maximum. When isometric torque tasks were added to the Valsalva manoeuvre, patterns of muscle activity (RA, OE, OI and ES) were significantly altered. For Valsalva with isometric trunk extension, activity from OE and OI was reduced while IAPs remained fairly constant. These findings indicate that in tasks where an IAP extension moment is warranted, abdominal pressure can be increased without the development of a large counter-moment produced by the dual action of the trunk flexors. Activation of other muscles such as the diaphragm and transversus abdominis is suggested as helping provide control over the level of IAP during controlled trunk tasks.

    The Study for Monitoring Antimicrobial Resistance Trends program monitors the activity of antibiotics against aerobic and facultative Gram-negative bacilli (GNBs) from intra-abdominal infections (IAIs) in patients worldwide. In 2011, 1 929 aerobic and facultative GNBs from 21 hospitals in 16 cities in China were collected. All isolates were tested using a panel of 12 antimicrobial agents, and susceptibility was determined following the Clinical Laboratory Standards Institute guidelines. Among the Gram-negative pathogens causing IAIs, Escherichia coli (47.3%) was the most commonly isolated, followed by Klebsiella pneumoniae (17.2%), Pseudomonas aeruginosa (10.1%), and Acinetobacter baumannii (8.3%). Enterobacteriaceae comprised 78.8% (1521/1929) of the total isolates. Among the antimicrobial agents tested, ertapenem and imipenem were the most active agents against Enterobacteriaceae, with susceptibility rates of 95.1% and 94.4%, followed by amikacin (93.9%) and piperacillin/tazobactam (87.7%). Susceptibility rates of ceftriaxone, cefotaxime, ceftazidime, and cefepime against Enterobacteriaceae were 38.3%, 38.3%, 61.1%, and 50.8%, respectively. The leastactive agent against Enterobacteriaceae was ampicillin/sulbactam (25.9%). The extended-spectrum β-lactamase (ESBL) rates among E. coli, K. pneumoniae, Klebsiella oxytoca, and Proteus mirabilis were 68.8%, 38.1%, 41.2%, and 57.7%, respectively. Enterobacteriaceae were the major pathogens causing IAIs, and the most active agents against the study isolates (including those producing ESBLs) were ertapenem, imipenem, and amikacin. Including the carbapenems, most agents exhibited reduced susceptibility against ESBL-positive and multidrug-resistant isolates.

    To evaluate the effect of increased intra-abdominal pressure (IAP) on the systolic and pulse pressure variations induced by positive pressure ventilation in a porcine model. Experimental study in a research laboratory. Seven mechanically ventilated and instrumented pigs prone to normovolaemia and hypovolaemia by blood withdrawal. Abdominal banding gradually increased IAP in 5-mmHg steps up to 30 mmHg. Variations in systolic pressure, pulse pressure, inferior vena cava flow, and pleural and transmural (LVEDPtm) left-ventricular end-diastolic pressure were recorded at each step. Systolic pressure variations were 6.1+/-3.1%, 8.5+/-3.6% and 16.0+/-5.0% at 0, 10, and 30 mmHg IAP in normovolaemic animals (mean+/-SD; p<0.01 for IAP effect). They were 12.7+/-4.6%, 13.4+/-6.7%, and 23.4+/-6.3% in hypovolaemic animals (p<0.01 vs normovolaemic group) for the same IAP. Fluctuations of the inferior vena cava flow disappeared as the IAP increased. Breath cycle did not induce any variations of LVEDPtm for 0 and 30 mmHg IAP. In this model, the systolic pressure and pulse pressure variations, and inferior vena cava flow fluctuations were dependent on IAP values which caused changes in pleural pressure swing, and this dependency was more marked during hypovolaemia. The present study suggests that dynamic indices are not exclusively related to volaemia in the presence of increased IAP. However, their fluid responsiveness predictive value could not be ascertained as no fluid challenge was performed.

    The objective was to determine the association between the abdominal seat belt sign and intra-abdominal injuries (IAIs) in children presenting to emergency departments with blunt torso trauma after motor vehicle collisions (MVCs). This was a planned subgroup analysis of prospective data from a multicenter cohort study of children with blunt torso trauma after MVCs. Patient history and physical examination findings were documented before abdominal computed tomography (CT) or laparotomy. Seat belt sign was defined as a continuous area of erythema, ecchymosis, or abrasion across the abdomen secondary to a seat belt restraint. The relative risk (RR) of IAI with 95% confidence intervals (CIs) was calculated for children with seat belt signs compared to those without. The risk of IAI in those patients with seat belt sign who were without abdominal pain or tenderness, and with Glasgow Coma Scale (GCS) scores of 14 or 15, was also calculated. A total of 3,740 children with seat belt sign documentation after blunt torso trauma in MVCs were enrolled; 585 (16%) had seat belt signs. Among the 1,864 children undergoing definitive abdominal testing (CT, laparotomy/laparoscopy, or autopsy), IAIs were more common in patients with seat belt signs than those without (19% vs. 12%; RR = 1.6, 95% CI = 1.3 to 2.1). This difference was primarily due to a greater risk of gastrointestinal injuries (hollow viscous or associated mesentery) in those with seat belt signs (11% vs. 1%; RR = 9.4, 95% CI = 5.4 to 16.4). IAI was diagnosed in 11 of 194 patients (5.7%; 95% CI = 2.9% to 9.9%) with seat belt signs who did not have initial complaints of abdominal pain or tenderness and had GCS scores of 14 or 15. Patients with seat belt signs after MVCs are at greater risk of IAI than those without seat belt signs, predominately due to gastrointestinal injuries. Although IAIs are less common in alert patients with seat belt signs who do not have initial complaints of abdominal pain or tenderness, the

    To evaluate in vitro susceptibilities of aerobic and facultative Gram-negative bacterial (GNB) isolates from intra-abdominal infections (IAIs) to 12 selected antimicrobials in Chinese hospitals from 2012 to 2014. Hospital acquired (HA) and community acquired (CA) IAIs were collected from 21 centers in 16 Chinese cities. Extended spectrum beta-lactamase (ESBL) status and antimicrobial susceptibilities were determined at a central laboratory using CLSI broth microdilution and interpretive standards. From all isolated strains the Enterobacteriaceae (81.1%) Escherichia coli accounted for 45.4% and Klebsiella pneumoniae for 20.1%, followed by Enterobacter cloacae (5.2%), Proteus mirabilis (2.1%), Citrobacter freundii (1.8%), Enterobacter aerogenes (1.8%), Klebsiella oxytoca (1.4%), Morganella morganii (1.2%), Serratia marcescens (0.7%), Citrobacter koseri (0.3%), Proteus vulgaris (0.3%) and others (1.0%). Non- Enterobacteriaceae (18.9%) included Pseudomonas aeruginosa (9.8%), Acinetobacter baumannii (6.7%), Stenotrophomonas maltophilia (0.9%), Aeromonas hydrophila (0.4%) and others (1.1%). ESBL-screen positive Escherichia coli isolates (ESBL+) showed a decreasing trend from 67.5% in 2012 to 58.9% in 2014 of all Escherichia coli isolates and the percentage of ESBL+ Klebsiella pneumoniae isolates also decreased from 2012 through 2014 (40.4% to 26.6%), which was due to reduced percentages of ESBL+ isolates in HA IAIs for both bacteria. The overall susceptibilities of all 5160 IAI isolates were 87.53% to amikacin (AMK), 78.12% to piperacillin-tazobactam (TZP) 81.41% to imipenem (IMP) and 73.12% to ertapenem (ETP). The susceptibility of ESBL-screen positive Escherichia coli strains was 96.77%-98.8% to IPM, 91.26%-93.16% to ETP, 89.48%-92.75% to AMK and 84.86%-89.34% to TZP, while ESBL-screen positive Klebsiella pneumoniae strains were 70.56%-80.15% susceptible to ETP, 80.0%-87.5% to IPM, 83.82%-87.06% to AMK and 63.53%-68.38% to TZP within the three year study

    Full Text Available Abstract Background Menopause is associated with increased adiposity, especially increased deposition of intra-abdominal (IA adipose tissue (AT. This differs from common or 'dietary' obesity, i.e., obesity apparently due to environmentally stimulated overeating, in which IAAT and subcutaneous (S AT increase in similar proportions. The effect of menopause on adiposity is thought to be due to the decreased secretion of ovarian estrogens. Ovariectomy in rats and other animals is a commonly used model of menopause. It is well known that ovariectomy increases adiposity and that this can be reversed by estradiol treatment, but whether ovariectomy selectively increases IAAT has not been measured directly. Therefore, we used micro-computed tomography (microCT to investigate this question in both chow-fed and dietary-obese rats. Methods Ovariectomized, ovariectomized and estradiol treated, and sham-operated (intact rats were fed chow or chow plus Ensure (Abbott Nutrition; n = 7/group. Total (T AT, IAAT and SAT were measured periodically by microCT. Regional distribution of AT was expressed as IAAT as a percentage of TAT (%IAAT. Excesses in these measures were calculated with respect to chow-fed intact rats to control for normal maturational changes. Chemical analysis of fat was done in chow-fed intact and ovariectomized rats at study end. Data were analyzed by t-tests and planned comparisons. Results Body mass, TAT, total fat mass, fat-free body mass, and %IAAT all increased in chow-fed intact rats during the 41 d study. In chow-fed rats, ovariectomy increased excess body mass, TAT, fat mass, fat-free body mass, and SAT, but had little effect on IAAT, in chow-fed rats, leading to a decrease in %IAAT. Ensure feeding markedly increased SAT, IAAT and TAT and did not significantly affect %IAAT. Ovariectomy had similar effects in Ensure-fed rats as in chow-fed rats, although less statistically reliable. Estradiol treatment prevented all the effects of

    Recently, the emergence of multidrug-resistant organisms such as extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae has raised considerable concern regarding the appropriate treatment of intra-abdominal infections (IAIs). In this study, we investigated the molecular characteristics of ESBL among clinical isolates of Escherichia coli and Klebsiella pneumoniae causing IAIs and their pattern of antimicrobial resistance, which can provide useful information about the epidemiology and risk factors associated with these infections. One hundred sixty-seven E.coli and 47 K. pneumoniae ESBL-producing strains causing IAIs were collected from 9 hospitals in China, during 2012 and 2013. The antimicrobial susceptibility profile of these strains was determined. Polymerase chain reaction and sequencing were performed to identify genes for β-lactamase (blaTEM, blaSHV, blaOXA-1-like, and blaCTX-M). The isolates were also analyzed by pulsed-field gel electrophoresis (PFGE). In 167 ESBL-producing E. coli strains, 104 strains (62.3%) were positive for CTX-M, and 9 strains (5.39%) were positive for SHV. Among the 47 K. pneumoniae strains, 35 strains (74.5%) were positive for SHV-2a, 12 strains (25.5%) were positive for CTX-M. No TEM-type and OXA-1-like strain was detected among all the ESBL-producing strains. Regarding the CTX-M-positive E. coli and K. pneumoniae strains, CTX-M-15 was the most common genotype in E. coli and K. pneumoniae strains, accounting for 28.7% and 17.0%, respectively, followed by CTX-M-55 accounting for 16.2% and 2.13%, respectively; the remaining genotypes included CTX-M-123 and CTX-M-82. PFGE showed that E.coli and K. pneumoniae ESBL-producing strains causing IAIs were diverse and that emerging resistance may not be due to the dissemination of national clones. The present study revealed that in ESBL-producing strains causing IAIs in China, the most common genotype for E.coli was CTX-M-15 and for K. pneumoniae was SHV-2a. However, there was a

    Full Text Available Background. Research on dairy foods to enhance weight and fat loss when incorporated into a modest weight loss diet has had mixed results. Objective. A 15-week controlled feeding study to determine if dairy foods enhance central fat and weight loss when incorporated in a modest energy restricted diet of overweight and obese adults. Design. A 3-week run-in to establish energy needs; a 12-week 500 kcal/d energy reduction with 71 low-dairy-consuming overweight and obese adults randomly assigned to diets: ≤1 serving dairy/d (low dairy, LD or ≤4 servings dairy/d (adequate dairy, AD. All foods were weighed and provided by the metabolic kitchen. Weight, fat, intra-abdominal adipose tissue (IAAT, subcutaneous adipose tissue (SAT macrophage number, SAT inflammatory gene expression, and circulating cytokines were measured. Results. No diet differences were observed in weight, fat, or IAAT loss; nor SAT mRNA expression of inflammation, circulating cytokines, fasting lipids, glucose, or insulin. There was a significant increase (P=0.02 in serum 25-hydroxyvitamin D in the AD group. Conclusion. Whether increased dairy intake during weight loss results in greater weight and fat loss for individuals with metabolic syndrome deserves investigation. Assessment of appetite, hunger, and satiety with followup on weight regain should be considered.

    It is not clear why some anovulatory women with polycystic ovary syndrome (PCOS) and obesity resume ovulation and others remain anovulatory after weight loss. The objective of this study was to compare the changes in body fat distribution and specifically intra-abdominal fat (IAF) and subcutaneous abdominal fat (SAF) between a group of anovulatory women with PCOS and obesity who resume ovulation (RO+) to those who remain anovulatory (RO-) during a lifestyle program. In a prospective pilot cohort study, anovulatory women with PCOS underwent a 6 month lifestyle program in a tertiary fertility clinic. Body fat distribution was assessed by anthropometrics, dual-energy X-ray absorptiometry (DEXA) and single slice abdominal CT scan at intake, after 3 months and after 6 months. Baseline-corrected changes over time were analysed using generalized estimating equations longitudinal regression analysis. In 32 anovulatory women with PCOS (age, 28 ± 4 years; BMI, 37.5 ± 5.0 kg/m²), there were no significant baseline differences in anthropometrics and biochemical assessment between 14 RO+ participants and 18 RO- participants. RO+ women lost more weight (6.3 versus 3.0%) and abdominal fat on DEXA (15.0 versus 4.3%) compared with RO- women. Resumption of ovulation was associated with early and consistent loss of IAF (12.4 versus 5.0% at 3 months and 18.5 versus 8.6% at 6 months). Loss of SAF between the RO+ women and the RO- women was similar at 3 months (6.2 versus 6.1%) but did not change any further in RO- women (6.1%) as it did in RO+ women (11.4%) at 6 months. In anovulatory women with PCOS and obesity undergoing a lifestyle program, RO+ women lose more body weight and abdominal fat on DEXA than RO- women. In addition, this study shows that early and consistent loss of IAF is associated with resumption of ovulation. Future studies should address the mechanisms behind these changes and should assess interventions aimed at loss of IAF to facilitate resumption of ovulation.

    Emergency department (ED) identification and radiographic evaluation of children with intra-abdominal injuries who need acute intervention can be challenging. To date, it is unclear if a clinical prediction rule is superior to unstructured clinician judgment in identifying these children. The objective of this study was to compare the test characteristics of clinician suspicion with a derived clinical prediction rule to identify children at risk of intra-abdominal injuries undergoing acute intervention following blunt torso trauma. This was a planned subanalysis of a prospective, multicenter observational study of children (trauma conducted in 20 EDs in the Pediatric Emergency Care Applied Research Network (PECARN). Clinicians documented their suspicion for the presence of intra-abdominal injuries needing acute intervention as 50% prior to knowledge of abdominal computed tomography (CT) scanning (if performed). Intra-abdominal injuries undergoing acute intervention were defined by a therapeutic laparotomy, angiographic embolization, blood transfusion for abdominal hemorrhage, or intravenous fluid administration for 2 or more days in those with pancreatic or gastrointestinal injuries. Patients were considered to be positive for clinician suspicion if suspicion was documented as ≥1%. Suspicion ≥ 1% was compared to the presence of any variable in the prediction rule for identifying children with intra-abdominal injuries undergoing acute intervention. Clinicians recorded their suspicion in 11,919 (99%) of 12,044 patients enrolled in the parent study. Intra-abdominal injuries undergoing acute intervention were diagnosed in 203 (2%) patients. Abdominal CT scans were obtained in the ED in 2,302 of the 2,667 (86%, 95% confidence interval [CI] = 85% to 88%) enrolled patients with clinician suspicion ≥1% and in 3,016 of the 9,252 (33%, 95% CI = 32% to 34%) patients with clinician suspicion undergoing acute intervention (197 of 203; 97.0%, 95% CI = 93.7% to 98.9%) was

    It is common knowledge that an increase of intra-abdomninal pressure (lAP) causes a decrease in the volume of cerebrospinal fluid in the lumbar and lower thoracic region, which may contribute to the development of more high spinal block. There is currently no research devoted to studying the impact of intra-abdominal pressure in pregnancy on the development of high spinal blockade. To investigate effects of intra-abdominal pressure in pregnancy on the development of spinal blockade and incidence of hypotension during cesarean section. 170 pregnant women with gestational age 38-40 weeks were included in the randomized, blinded, controlled study. All the women received elective cesarean section under spinal anesthesia (SA). Pregnant women w|,ere divided into two groups of 85 females each. In the first group, the anesthesiologist did not know the value of lAP and used the dose of local anesthetic focusing on height, weight, and according to his own experience. In the second group, an anesthesiologist corrected dose of local anesthetic depending on the lAP and also considered the height and weight of a woman. In 9.2% of women, lAP was less than 11 mmHg (physiologically normal), in 49%--from 12 to 15 mmHg (degree I of intra-abdominal hypertension (IAH)), in 40.3%--from 16 to 20 mmHg (degree II of IAH), in 1.5%--from 21 to 25 mmHg (degree III of IAH). In the first group, the incidence of high spinal block (above Th4) and incidence of arterial hypotension (systolic blood pressure under 90 mm.Hg) was two times higher than in the second group (phypotension. To prevent these complications, we recommend decreasing the dose of local anesthetic with use of the Scale of the Risk of developing high spinal block in pregnant.

    Full Text Available BACKGROUND Fine-Needle Aspiration Cytology (FNAC is a widely used method, which is accurate and safe in a readily palpable masses. But, in those inaccessible lesions and deeper organs are safely aspirated using fine needle radiological procedure like ultrasound or computed tomography guided. The aim of the study is to assess the utility of FNAC in the diagnosis of intra-abdominal lesions and different pattern of lesions in particular to the sites. MATERIALS AND METHODS This retrospective study was done in the Department of Pathology, Regional Institute of Medical Sciences (RIMS, Imphal, between June 2010 and June 2016. The study included 128 intra-abdominal masses. Giemsa and Papanicolaou’s stains were used. The cytological diagnosis was correlated with clinical and radiological data to arrive at a final diagnosis. RESULTS Reports on FNAC smears were retrospectively analysed, which had been done in various anatomic sites- liver (70 cases, colon (19 cases, gallbladder (17 cases, mesenteric lymph nodes (12 cases, ovary (3 cases, adrenals (2 cases and 1 case each of pancreas, peritoneal wall, pelvic, suprapubic and flank masses. The mean age was 42.16 years with M:F of 1.3:1. The diagnostic yield was 85.2% in combination for Ultrasound Guided (USG and Computed Tomography (CT guided aspiration. The smears were classified as benign neoplastic, malignant neoplastic, non-neoplastic, inconclusive and unsatisfactory for interpretation. There were 79 (61.7% malignant neoplastic lesion, 5 (3.9% benign neoplastic lesion, 25 (19.5% non-neoplastic lesion, one (0.7% inconclusive lesions and 18 (14.1% unsatisfactory smears. The liver and the colon were the most common sites. Adenocarcinomas and Hepatocellular Carcinoma (HCC were the most common malignant lesions comprising of 35 (44.3% and 25 (31.6% of the total malignant lesions diagnosed. CONCLUSION Intra-abdominal FNA is a simple, economical and a safe procedure with high sensitivity, specificity and

    Recently, the overall incidence of tuberculosis has decreased, but the incidence of an extrapulmonary manifestation in patients with tuberculosis has increased in the Republic of Korea. Although intestinal tuberculosis is not infrequent, a fistula caused by tuberculosis is a rare condition. A 23-year-old man presented with fever, diarrhea and right lower quadrant pain. A computed tomography (CT) scan revealed a lobulated, peripherally enhancing, low density mass in the mesentery. The patient underwent laparoscopic biopsy for necrotic lymph node, and intra-abdominal tuberculous lymphadenitis was diagnosed. Four months after initiating treatment with anti-tuberculous medication, the patient developed fever together with lower abdominal pain. A follow-up CT scan revealed a fistulous tract that had developed between the initially noted lymphadenopathy and the proximal ascending colon. Laparoscopic right hemicolectomy was performed as a curative treatment. This case suggests that a nodo-colonic fistula may occur as a paradoxical response in patients with intra-abdominal tuberculous lymphadenitis during treatment with anti-tuberculous medication.

    Purpose: To validate abdominal ultrasonography and helical computed tomography in detecting causes for sepsis in patients after abdominal surgery and to determine improved criteria for its use. Materials and methods: Eighty-five consecutive surgical patients primarily operated for non-infectious disease were included in this prospective study. Forty-one patients were admitted to the intensive care unit. All patients were suspected of an intra-abdominal sepsis after abdominal surgery. Both ultrasonography (US) and helical abdominal computed tomography (CT) were performed to investigate the origin of an intra-abdominal sepsis. The images of both US and CT were interpreted on a four-point scale by different radiologists or residents in radiology, the investigators were blinded of each other's test. Interpretations of US and CT were compared with a reference standard which was defined by the result of diagnostic aspiration of suspected fluid collections (re)laparotomy, clinical course or the opinion of an independent panel. Likelihood ratios and post-test probabilities were calculated and interobserver agreement was determined using κ statistics. Results: The overall prevalence of an abdominal infection was 0.49. The likelihood ratio (LR) of a positive test-result for US was 1.33 (95% CI: 0.8-2.5) and for CT scan 2.53 (95% CI: 1.4-5.0); corresponding post-test probabilities for US 0.57 (95% CI: 0.42-0.70) and for CT 0.71 (95% CI: 0.57-0.83). The LR of a negative test-result was, respectively, 0.60 (95% CI: 0.3-1.3) and 0.18 (95% CI: 0.06-0.5); corresponding post-test probabilities for US 0.37 (95% CI: 0.20-0.57) and for CT 0.15 (95% CI: 0.06-0.32) were calculated. Conclusion: Computed tomography can be used as the imaging modality of choice in patients suspected of intra-abdominal sepsis after abdominal surgery. Because of the low discriminatory power ultrasonography should not be performed as initial diagnostic test

    Full Text Available Abstract Recently, an update of the IDSA guidelines for the treatment of complicated intraabdominal infections has been published. No guideline can cater for all variations in ecology, antimicrobial resistance patterns, patient characteristics and presentation, health care and reimbursement systems in many different countries. In the short time the IDSA guidelines have been available, a number of practical clinical issues have been raised by physicians regarding interpretation of the guidelines. The main debatable issues of the new IDSA guidelines are described as follows: The authors of the IDSA guidelines present recommendations for the following subgroups of "complicated" IAI: community-acquired intra-abdominal infections of mild-to-moderate and high severity and health care-associated intra-abdominal infections (no general treatment recommendations, only information about antimicrobial therapy of specific resistant bacterial isolates. From a clinical point of view, "complicated" IAI are better differentiated into primary, secondary (community-acquired and postoperative and tertiary peritonitis. Those are the clinical presentations of IAI as seen in the emergency room, the general ward and on ICU. Future antibiotic treatment studies of IAI would be more clinically relevant if they included patients in studies for the efficacy and safety of antibiotics for the treatment of the above mentioned forms of IAI, rather than conducting studies based on the vague term "complicated" intra-abdominal infections. The new IDSA guidelines for the treatment of resistant bacteria fail to mention many of new available drugs, although clinical data for the treatment of "complicated IAI" with new substances exist. Further-more, treatment recommendations for cIAI caused by VRE are not included. This group of diseases comprises enough patients (i.e. the entire group of postoperative and tertiary peritonitis, recurrent interventions in bile duct surgery or

    Up to 93% of patients undergoing abdominal surgery will develop intra-abdominal adhesions with the subsequent morbidity that they represent. Various substances have been tested for the prevention of adhesions with controversial results; the aim of our study is to compare the capability of pirfenidone in adhesion prevention against sodium hyaluronate/carboxymethylcellulose. A randomized, prospective, longitudinal experimental study with Winstar rats. They were divided into 3 groups. The subjects underwent an exploratory laparotomy and they had a 4cm(2) cecal abrasion. The first group received saline on the cecal abrasion, and groups 2 and 3 received pirfenidone and sodium hyaluronate/carboxymethylcellulose respectively. All rats were sacrificed on the 21st day after surgery and the presence of adhesions was evaluated with the modified Granat scale. Simple frequency, central tendency and dispersion measures were recorded. For the statistical analysis we used Fisher's test. To evaluate adhesions we used the Granat's modified scale. The control group had a median adhesion formation of 3 (range 0-4). The pirfenidone group had 1.5 (range 0-3), and the sodium hyaluronate/carboxymethylcellulose group had 0 (range 0-1). There was a statistically significant difference to favor sodium hyaluronate/carboxymethylcellulose against saline and pirfenidone (P<0.009 and P<.022 respectively). The use of sodium hyaluronate/carboxymethylcellulose is effective for the prevention of intra-abdominal adhesions. More experimental studies are needed in search for the optimal adhesion prevention drug. Copyright © 2015 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available Background: Intra-abdominal adhesions after surgery are usually in the form of bands and can annoy the patient throughout life causing repeated surgical procedures. Therefore, any action to prevent adhesions after surgery can increase longevity and quality of life. For this aim, this study investigates the effect of streptokinase and normal saline on the 7th day and 1 month after laparotomy. Materials and Methods: Experimental study was conducted on thirty healthy male Wistar rats weighing 200–250 g with age of 3 months divided into three groups of 10. Group I: No treatment, Group II: Received normal saline, and Group III: Received normal saline and streptokinase at the same time. One week and 1 month after laparotomy, the frequency of the presence or absence of adhesion bands was performed by a person who was unaware of the sample grouping. The collected information was analyzed with the SPSS software (version 16; SPSS Inc., Chicago, IL, USA. Results: Adhesion frequency was found to be 20% on the 7th day (early and 1 month after laparotomy (late for Group 1, and it was 40% on early and late for Group II, while 0% on the early and late for Group III. Hence, in the group receiving streptokinase, no early or late adhesion was observed; therefore, it had a significant role in the prevention of intra-abdominal adhesions (P 0.05. Conclusion: According to the results of our study, we believe that streptokinase could be a good antiadhesive agent considering its effectiveness.

    . METHODS: Eight Agroceres pigs were submitted to five different clinical scenarios after instrumentation: 1 a baseline condition with low intra-abdominal pressure and healthy lungs; 2 pneumoperitoneum with 20 mmHg intra-abdominal pressure; 3 acute lung injury induced by pulmonary lavage with surfactant deactivation; 4 pneumoperitoneum with 20 mmHg intra-abdominal pressure with lung pulmonary injury and low positive end-expiratory pressure; and 5 27 cmH2O positive end-expiratory pressure with pneumoperitoneum and acute lung injury. Respiratory and hemodynamic variables were collected. A multivariate analysis was conducted to search for variables associated with increased intracranial pressure in the five scenarios. RESULTS: Only plateau airway pressure showed a positive correlation with intracranial pressure in the multivariate analysis. In the models with acute lung injury, plateau airway pressure, CO2 arterial pressure, end tidal CO2 and central venous pressure were positively correlated with increased intracranial pressure. CONCLUSION: In a model of multiple organ dysfunction with associated clinical conditions causing increased intra-thoracic and abdominal pressure, increased intracranial pressure triggered by elevated intra-abdominal pressure is apparently caused by worsened respiratory system compliance and a reduced brain venous drainage gradient due to increased central venous pressure.

    Full Text Available Abstract Background Obesity remains a major public health problem, associated with a cluster of metabolic abnormalities. However, individuals exist who are very obese but have normal metabolic parameters. The aim of this study was to determine to what extent differences in metabolic health in very obese women are explained by differences in body fat distribution, insulin resistance and level of physical activity. Methods This was a cross-sectional pilot study of 39 obese women (age: 28-64 yrs, BMI: 31-67 kg/m2 recruited from community settings. Women were defined as 'metabolically normal' on the basis of blood glucose, lipids and blood pressure. Magnetic Resonance Imaging was used to determine body fat distribution. Detailed lifestyle and metabolic profiles of participants were obtained. Results Women with a healthy metabolic profile had lower intra-abdominal fat volume (geometric mean 4.78 l [95% CIs 3.99-5.73] vs 6.96 l [5.82-8.32] and less insulin resistance (HOMA 3.41 [2.62-4.44] vs 6.67 [5.02-8.86] than those with an abnormality. The groups did not differ in abdominal subcutaneous fat volume (19.6 l [16.9-22.7] vs 20.6 [17.6-23.9]. A higher proportion of those with a healthy compared to a less healthy metabolic profile met current physical activity guidelines (70% [95% CIs 55.8-84.2] vs 25% [11.6-38.4]. Intra-abdominal fat, insulin resistance and physical activity make independent contributions to metabolic status in very obese women, but explain only around a third of the variance. Conclusion A sub-group of women exists who are metabolically normal despite being very obese. Differences in fat distribution, insulin resistance, and physical activity level are associated with metabolic differences in these women, but account only partially for these differences. Future work should focus on strategies to identify those obese individuals most at risk of the negative metabolic consequences of obesity and on identifying other factors that

    Although in the last decade the management of invasive fungal infections has improved, a number of controversies persist regarding the management of complicated intra-abdominal infection and surgical extended length-of-stay (LOS) patients in intensive care unit (ICU). To identify the essential clinical knowledge and elaborate a set of recommendations, with a high level of consensus, necessary for the management of postsurgical patients with complicated intra-abdominal infection and surgical patients with ICU extended stay. A Spanish prospective questionnaire, which measures consensus through the Delphi technique, was anonymously answered and e-mailed by 30 multidisciplinary national experts, all of them specialists in fungal invasive infections from six scientific national societies; these experts were intensivists, anesthesiologists, microbiologists, pharmacologists and specialists in infectious diseases. They answered 11 questions drafted by the coordination group after conducting a thorough review of the literature published in the last few years. For a category to be selected, the level of agreement among the experts in each should be equal to or greater than 70%. In a second round, 73 specialists attended a face-to-face meeting which was held after extracting recommendations from the chosen topics and in which they validated the pre-selected recommendations and derived algorithm. After the second Delphi round, the following 11 recommendations with high degree of consensus were validated. For "surgical patients" seven recommendations were validated: (1) risk factors for invasive candidiasis (IC), (2) usefulness of blood culture and direct examination of abdominal fluid to start empirical treatment; (3) PCR for treatment discontinuation; (4) start antifungal treatment in patients with anastomotic leaks; (5) usefulness of Candida score (CS) but not (6) the Dupont score for initiating antifungal therapy in the event of anastomotic leakage or tertiary peritonitis

    Work-up for patients presenting to the Emergency Department (ED) following an anterior abdominal stab wound (AASW) has been debated since the 1960s. Experts agree that patients with peritonitis, evisceration, or hemodynamic instability should undergo immediate laparotomy (LAP), however, workup of stable, asymptomatic or non-peritoneal, patients is not clearly defined. To evaluate the accuracy of computed tomography of abdomen and pelvis (CTAP) for diagnosis of intra-abdominal injuries requiring Therapeutic Laparotomy (THER-LAP) in ED patients with AASW. Is a negative CT scan without a period of observation sufficient to safely discharge a hemodynamically stable, asymptomatic AASW patient? We searched PUBMED, EMBASE, and Scopus from their inception until May 2017 for studies on ED patients with AASW. We defined the reference standard test as LAP for patients who were managed surgically and those with THER-LAP were considered as disease-positive. In those who were managed nonsurgically, inpatient observation was considered the reference standard. We used the Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS-2) to evaluate the risk of bias and applicability of the included studies. We attempted to compute the pooled sensitivity, specificity, Likelihood Ratios (LR+, LR-) using a random-effects model with MetaDiSc software and calculate testing and treatment thresholds for CT scan applying the Pauker and Kassirer model. Seven studies were included encompassing 575 patients. The weighted prevalence of THER-LAP was 34.3% (95% CI 30.5-38.2%). Studies had variable quality and the inclusion criteria were not uniform. The operating characteristics of CT scan were: sensitivity 50%-100%, specificity 39%-97%, LR+ 1.0-15.7 and LR- 0.07-1.0. The high heterogeneity (I-square>75%) of the operating characteristics of CT scan prevented pooling of the data and therefore the testing and treatment thresholds could not be estimated. The articles revealed a high prevalence (8

    Full Text Available Abstract Background The recommendations outlined in the latest guidelines published by the Surgical Infection Society (SIS and the Infectious Disease Society of America (IDSA regarding the proper duration of antibiotic therapy in patients with intra-abdominal infections are limited and non-specific. This ambiguity is due mainly to the lack of clinical trials on the topic of optimal duration of therapy. It is well known that the overuse of antibiotics has several important consequences such as increased treatment costs, reduced clinical efficacy, and above all, the increased emergence of antibiotic-resistant pathogens. Ampicillin-Sulbactam is a commonly used "first line" antibiotic for intra-abdominal infections. Ertapenem and Ampicillin-sulbactam are recommended as primary treatment agents for localized peritonitis by both the SIS and IDSA guidelines. Methods/Design This study is a prospective multi-center randomized investigation. The study will be performed in the Departments of General, Emergency, and Transplant Surgery of Sant'Orsola-Malpighi University Hospital in Bologna, Italy, in the General Surgery Department of the Ospedali Riuniti of Bergamo, Italy, and in the Trauma and Emergency Surgery Department of Maggiore Hospital in Bologna, Italy, and will be conducted by all surgeons willing to participate in the study. The inclusion period of the study will take approximately two years before the planned number of 142 enrolled patients is reached. Discussion Ertapenem and Ampicillin-sulbactam are recommended both as primary treatment agents for localized peritonitis by both the SIS and IDSA guidelines. As one of the discussed topic is the optimal duration of the antibiotic therapy and this ambiguity is due mainly to the lack of clinical trials on the topic, the present study aims for obtain precise data.

    The risk of infection in patients with rheumatic diseases is elevated, but a clear marker to differentiate the cause of the systemic inflammation is missing. We assessed the ability urinary immunoglobulin free light chains (FLCs) to indicate the presence of infection in patients with rheumatic disease. We performed a retrospective analysis of patients with rheumatic disease attending the Georg-August University Hospital in Goettingen, Germany, from January 2011 to December 2013. Subjects were included if they had urine levels of κ and λ FLCs available. A reference group of patients without autoimmune disease, but with documented infection, was constructed. A total of 1500 patients had their urinary FLCs quantified during the study period. Of the 382 patients with rheumatic disease, 172 (45%) displayed no systemic inflammation, 162 (42%) had inflammation due to the underlying disease activity, and 48 (13%) had inflammation due to a confirmed infection. Urinary FLC concentrations were much higher in patients with rheumatic diseases and infection (κ 68.8 ± 81.8 mg/L, λ 31.4 ± 53.5 mg/L) compared to those with inflammation due to rheumatic disease activity (κ 22.7 ± 26.3 mg/L, λ 8.1 ± 9.1 mg/L, κ p infection, with a sensitivity of 63% and specificity of 84%. Urinary λ FLCs gave similar values, with a sensitivity of 65% and specificity of 81%. FLCs may be useful for distinguishing inflammation due to rheumatic disease activity from that due to the additional presence of infection. The ability to quantify these proteins in urine provides a simple alternative to the use of blood.

    Although carbohydrate antigen (CA) 19-9 is a useful tumor marker for pancreatic cancer, it can also become elevated from a variety of benign and malignant conditions. Herein we describe an unusual presentation of elevated CA 19-9 in an asymptomatic patient who had previously undergone adjuvant chemotherapy and radiation therapy for resected early stage pancreatic cancer. The rise in CA 19-9 might be due to delayed radiation-induced inflammation related to previous intra-abdominal radiation therapy with or without radiation recall induced by gemcitabine. After treatment with corticosteroids the CA 19-9 level decreased to normal, and the patient has not developed any evidence of recurrent cancer to date.

    We report 10 cases of pulmonary atelectasis diagnosed by chest computed tomography in patients with neurological or muscular disease. Atelectasis was frequently seen in hypotonic patients who could not roll over on their own. The atelectases located mostly in the dorsal bronchopulmonary segments, adjacent to the heart or diaphragm. Atelectasis diminished in two patients after they became able to roll themselves over. Gravity-related lung compression by the heart and intra-abdominal organs on persistent supine position can cause pulmonary atelectasis in patients with neurological or muscular disease who can not roll over by their own power. To confirm that the prone position reduces compression of the lungs, chest computed tomography was performed in both the supine and the prone position in three patients. Sagittal images with three-dimensional computed tomographic reconstruction revealed significant sternad displacements of the heart and caudal displacements of the dorsal portion of the diaphragm on prone position compared with supine position. The prone position, motor exercises for rolling over, and biphasic cuirass ventilation are effective in reducing gravity-related lung compression. Some patients with intellectual disabilities were also able to cooperate in chest physiotherapy. Chest physiotherapy is useful in preventing atelectasis in patients with neurological or muscular disease. (author)

    We investigated the trend in resistance to carbapenems among isolates of Enterobacteriaceae that had been collected from patients with intra-abdominal infections at five medical centers in Taiwan from 2006 to 2010 and evaluated the correlation between resistance to carbapenems and consumption of said agents as part of the Study for Monitoring Antimicrobial Resistance Trends (SMART). During the study period, the usage of ertapenem and that of total carbapenems (ertapenem, imipenem, and meropenem) increased significantly from 6.13 to 13.38 defined daily doses per 1000 patient-days for ertapenem and from 20.43 to 34.25 defined daily doses per 1000 patient-days for total carbapenems. The most common species were Escherichia coli (n = 1095), Klebsiella spp. (n = 663), and Enterobacter spp. (n = 202). The susceptibility of all isolates to ertapenem and to imipenem varied during the study period. For ertapenem, the rates of nonsusceptibility ranged from 3.5% to 10.3% and those for imipenem ranged from 3.5% to 10.7%. Although the use of carbapenems increased during the study period, there was no marked increase in resistance to carbapenems. Continuous monitoring of resistance trends is necessary so that antimicrobial prescription policies can be adjusted and infection control intervention programs can be implemented.

    Time to source control plays a determinant prognostic role in patients having severe intra-abdominal infections (IAIs). Open abdomen (OA) management became an effective treatment option for peritonitis. Aim of this study was to analyze the correlation between time to source control and outcome in patients presenting with abdominal sepsis and treated by OA. We retrospectively analyzed 111 patients affected by abdominal sepsis and treated with OA from May 2007 to May 2015. Patients were classified according to time interval from first patient evaluation to source control. The end points were intra-hospital mortality and primary fascial closure rate. The in-hospital mortality rate was 21.6% (24/111), and the primary fascial closure rate was 90.9% (101/111). A time to source control ≥6 h resulted significantly associated with a poor prognosis and a lower fascial closure rate (mortality 27.0 vs 9.0%, p = 0.04; primary fascial closure 86 vs 100%, p = 0.02). We observed a direct increase in mortality (and a reduction in closure rate) for each 6-h delay in surgery to source control. Early source control using OA management significantly improves outcome of patients with severe IAIs. This damage control approach well fits to the treatment of time-related conditions, particularly in case of critically ill patients.

    Full Text Available Gram-negative ESKAPE pathogens (Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species are important etiologic agents of nosocomial infection that are frequently resistant to broad-spectrum antimicrobial agents. Gram-negative ESKAPE pathogens were collected from hospitalized patients in 11 Latin American countries from 2013 to 2015 as part of the Study for Monitoring Antimicrobial Resistance Trends (SMART global surveillance program. In total, 2113 isolates from intra-abdominal infections (IAI and 970 isolates from urinary tract infections (UTI were tested against antimicrobial agents using standardized CLSI broth microdilution methodology. Of the agents tested, amikacin demonstrated the highest rates of susceptibility (% for K. pneumoniae (92.2, 92.3, Enterobacter spp. (97.5, 92.1, and P. aeruginosa (85.3, 75.2 isolates from both IAI and UTI, respectively. Ertapenem (68.5, 62.6 and imipenem (79.2, 75.9 showed substantially higher rates of susceptibility (% than other β-lactams, including piperacillin-tazobactam (35.9, 37.4 against ESBL-positive isolates of K. pneumoniae from IAI and UTI, respectively. Rates of susceptibility to all agents tested against A. baumannii were ≤30.9%. Gram-negative ESKAPE pathogens isolated from Latin America demonstrated compromised in vitro susceptibility to commonly prescribed broad-spectrum, parenteral antimicrobial agents. Continued surveillance is warranted. New antimicrobial agents with potent activity against Gram-negative ESKAPE pathogens are urgently needed.

    We hypothesized that a longer duration of antibiotic treatment for intra-abdominal infections (IAI) would be associated with an increased risk of extra-abdominal infections (EAI) and high mortality. We reviewed all IAI occurring in a single institution between 1997 and 2010. The IAI were divided into two groups consisting of those with a subsequent EAI and those without; the data for each group were analyzed. Patients with EAI following IAI were matched in a 1:2 ratio with patients who did not develop EAI on the basis of their Acute Physiology and Chronic Health Evaluation (APACHE II) score±1 point. Statistical analyses were done with the Student t-test, χ(2) analysis, Wilcoxon rank sum test, and multi-variable analysis. We identified 2,552 IAI, of which 549 (21.5%) were followed by EAI. Those IAI that were followed by EAI were associated with a longer initial duration of antimicrobial therapy than were IAI without subsequent EAI (median 14 d [inter-quartile range (IQR) 10-22 d], vs. 10 d [IQR 6-15 d], respectively, pEAI following IAI in patients treated initially with antibiotics for 0-7 d was 13.3%, vs. 25.1% in patients treated initially for >7 d (pEAI to 938 patients without subsequent EAI, resulting in a mean APACHE II score of 15.2 for each group. After matching, IAI followed by EAI were associated with a longer duration of initial antimicrobial therapy than were IAI without subsequent EAI (median 14 d [9-22 d], vs. 11 d [7-16 d], respectively, pEAI (pEAI and increased mortality.

    Muscle size of the hamstring and gluteus maximus (GM) as well as intra-abdominal pressure (IAP) are considered as factors affecting the torque development during hip extension. This study examined the associations of torque development during maximal voluntary isometric hip extension with IAP and muscle size of the hamstring and GM. Anatomical cross-sectional area (ACSA) of the hamstring and thickness of GM were determined in 20 healthy young males using an ultrasonography apparatus (Experiment 1). Torque and IAP were simultaneously measured while subjects performed maximal voluntary isometric hip extension. The IAP was measured using a pressure transducer placed in the rectum and determined at the time at which the developed torque reached to the maximal. In Experiment 2, torque and IAP were measured during maximal voluntary isometric hip flexion in 18 healthy young males. The maximal hip extension torque was significantly correlated with the IAP (r = 0.504, P = 0.024), not with the ACSA of the hamstring (r = 0.307, P = 0.188) or the thickness of GM (r = 0.405, P = 0.076). The relationship was still significant even when the ACSA of the hamstring and the thickness of GM were adjusted statistically (r = 0.486, P = 0.041). The maximal hip flexion torque was not significantly correlated with the IAP (r = -0.118, P = 0.642). The current results suggest that IAP can contribute independently of the muscle size of the agonists to maximal voluntary hip extension torque.

    Full Text Available Inducing beige fat from white adipose tissue (WAT is considered to be a shortcut to weight loss and increasingly becoming a key area in research into treatments for obesity and related diseases. However, currently, animal models of beige fat are restricted to rodents, where subcutaneous adipose tissue (sWAT, benign WAT is more liable to develop into the beige fat under specific activators than the intra-abdominal adipose tissue (aWAT, malignant WAT that is the major source of obesity related diseases in humans.Here we induced beige fat by cold exposure in two species of bats, the great roundleaf bat (Hipposideros armiger and the rickett's big-footed bat (Myotis ricketti, and compared the molecular and morphological changes with those seen in the mouse. Expression of thermogenic genes (Ucp1 and Pgc1a was measured by RT-qPCR and adipocyte morphology examined by HE staining at three adipose locations, sWAT, aWAT and iBAT (interscapular brown adipose tissue.Expression of Ucp1 and Pgc1a was significantly upregulated, by 729 and 23 fold, respectively, in aWAT of the great roundleaf bat after exposure to 10°C for 7 days. Adipocyte diameters of WATs became significantly reduced and the white adipocytes became brown-like in morphology. In mice, similar changes were found in the sWAT, but much lower amounts of changes in aWAT were seen. Interestingly, the rickett's big-footed bat did not show such a tendency in beige fat.The great roundleaf bat is potentially a good animal model for human aWAT browning research. Combined with rodent models, this model should be helpful for finding therapies for reducing harmful aWAT in humans.

    Sepsis is a leading cause of death around the world, and 73-83% of all sepsis cases requiring attention in intensive care units are linked to intra-abdominal infection (IAI) or pneumonia. The activation of innate immunity is central to the manifestation of sepsis, and toll-like receptor (TLR) 4 plays an important role in this activation process. The 299G and 399I alleles of TLR4 have been linked with an increased risk of Gram-negative bacteria (GNB) infections and septic shock in some populations. This case-control study evaluated the prevalence of D299G/T399I polymorphisms in Mexican patients with IAI and/or pneumonia and in healthy controls. Genotyping revealed that 1 in 44 patients (2.3%; CI 95%: 0.05-12.0%) and 4 in 126 controls (3.2%; CI 95%: 0.9-7.9%) were heterozygous for both the D299G and T399l polymorphisms (OR: 0.71, CI 95%: 0.01-7.44, p = NS), confirming the co-segregation of these alleles in this population. Furthermore, the patients with a GNB infection and severe sepsis were not carriers of the risk alleles. In summary, this report shows that the frequency of the D299G and T399I polymorphisms in Mexican-Mestizos is lower than anticipated in comparison with other ethnic groups, emphasizing the variable distribution of TLR4 polymorphisms among different populations. Consequently, this study was not able to detect associations between TLR4 polymorphisms and sepsis in this population. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Objective: To analyze the comparative efficacy of piperacillin-tazobactam (PIP-TAZ and ceftriaxone-sulbactam with adjuvant (CSA in the treatment of intra-abdominal infections (IAIs and to assess the costs associated with respective therapies. Methods: The present study analyzed the data collected from 94 IAI patients treated at a tertiary-care hospital. Patient characteristics, infection types, surgical procedures, antibiotic therapies, treatment durations were recorded and overall cost involved in the infections management was estimated in Indian rupee. Results: In total, 46 patients received PIP-TAZ and 48 patients received CSA. The clinical cure was seen in 39.13% patients of PIP-TAZ group and 62.50% patients of CSA group. The patients diagnosed with mixed culture (Gram-positive and negative infections, needed additional cover of clindamycin to achieve clinical success. The failure patients from PIP-TAZ group were shifted to meropenem therapy. For the patients where meropenem and CSA therapy failed, colistin was given as an additional cover. Comparative cost expenditure analysis of the two drug treatment groups revealed that, the overall treatment cost for patients cured with empirical PIP-TAZ group was 51.79% more than that of CSA therapy. The strongest predictor of the increase in treatment costs was clinical failure. Similar trends were maintained for the patients cured with clindamycin additional therapy and change of therapy, with PIP-TAZ group accounting 36.11% and 39.99% more expenditure than CSA group. Conclusions: This study demonstrates that CSA has comparatively higher efficacy as compared to PIP-TAZ when used along with metronidazole in patients with different types of IAIs. Pharmacoeconomic analysis clearly shows that starting appropriate empirical antibiotic therapy has a large impact on the cost of treatment in management of IAIs and selection of CSA, can significantly reduce the cost involved in the treatment.

  5. Lactoferrin: Balancing Ups and Downs of Inflammation Due to Microbial Infections

    Full Text Available Lactoferrin (Lf is a glycoprotein of the primary innate immune-defense system of mammals present in milk and other mucosal secretions. This protein of the transferrin family has broad antimicrobial properties by depriving pathogens from iron, or disrupting their plasma membranes through its highly cationic charge. Noteworthy, Lf also exhibits immunomodulatory activities performing up- and down-regulation of innate and adaptive immune cells, contributing to the homeostasis in mucosal surfaces exposed to myriad of microbial agents, such as the gastrointestinal and respiratory tracts. Although the inflammatory process is essential for the control of invasive infectious agents, the development of an exacerbated or chronic inflammation results in tissue damage with life-threatening consequences. In this review, we highlight recent findings in in vitro and in vivo models of the gut, lung, oral cavity, mammary gland, and liver infections that provide experimental evidence supporting the therapeutic role of human and bovine Lf in promoting some parameters of inflammation and protecting against the deleterious effects of bacterial, viral, fungal and protozoan-associated inflammation. Thus, this new knowledge of Lf immunomodulation paves the way to more effective design of treatments that include native or synthetic Lf derivatives, which may be useful to reduce immune-mediated tissue damage in infectious diseases.

Los enfermos con presión intrabdominal > 20 cm. H2O tenían más porcentaje de hernias (50% vs 12 % y fugas pericatéter (37 % vs. 12 %. Como principales conclusiones, podemos destacar que los niveles de presión intrabdominal de nuestros pacientes son algo más elevados que en otras series. A mayor edad, mayor comorbilidad y mayor índice de masa corporal, la presión intrabdominal es más elevada. Los enfermos con presión intrabdominal elevada presentaron más episodios de hernias y fugas.Normal intra-abdominal pressure is equal to atmospheric pressure (zero. In peritoneal dialysis the introduction of intra-peritoneal liquid increases intra-abdominal pressure. In various studies it is recommended that this does not exceed 16-20cm H2O. In addition to possible abdominal discomfort, high intra-abdominal pressure can be linked to problems with the abdominal wall, such as hernias and fugues, and have implications for peritoneal transport and ultrafiltration deficit. The aims of this study were the following: to find out the intra-abdominal pressure levels in the prevalent type of patients in peritoneal dialysis, to assess the factors influencing the values for this pressure and to study the relationship between intra-abdominal pressure and the development of hernias and fugues, retrospectively. A transversal, observational and retrospective study was conducted to measure intra-abdominal pressure in the prevalent, stable patients who had been on peritoneal dialysis for more than three months. Intra-abdominal pressure was measured using the method described by Durand: patient in a supine position, with diurnal peritoneal volume. The final intra-abdominal pressure is the average of the measurements taken during inspiration and expiration, is expressed in cm H2O and the volume drained is

    Complicated skin and skin structure infections (cSSSIs) and intra-abdominal infections (IAIs) are problematic due to decreasing therapeutic options available against multidrug-resistant pathogens common among these types of infections. A total of 2245 isolates from African and the Middle Eastern (AfME) countries were collected to determine in vitro activity for tigecycline and comparators during 2007-2012 as part of the Tigecycline Evaluation Surveillance Trial program. Tigecycline was launched in the AfME in 2007 and remains active against a wide range of targeted pathogens worldwide. Isolates were recovered from cSSSI (1990) and IAI (255) from 38 sites in 11 AfME countries. Staphylococcus aureus was the most common species from cSSSI (27.9%), and the methicillin-resistant S. aureus rate was 25%. Enterococcus spp. (7.1%) and Streptococcus agalactiae (2.9%) were other common Gram-positive pathogens represented. Enterobacter spp. (14.5%), Pseudomonas aeruginosa (13.9%), Escherichia coli (11.4%), Klebsiella spp. (10.9%), and Acinetobacter spp. (7.2 %) were the most common Gram-negative species collected. Tigecycline MIC(90) values were 0.25 μg/mL against S. aureus. E. coli and Enterobacter spp. had tigecycline MIC(90) values of 1 and 2 μg/mL, respectively. E. coli was the most frequently collected species from IAI (28.3%), followed by Klebsiella spp. (20.8%), Enterococcus spp. (11.8%), and Stenotrophomonas maltophilia (6.3%). Isolates collected from IAI had the following tigecycline MIC(90) values: E. coli (1 μg/mL), Klebsiella spp. and other Enterobacteriaceae (2 μg/mL), Enterococcus spp. (0.25 μg/mL), and S. maltophilia (1 μg/mL). Tigecycline in vitro activity was observed against a broad spectrum of bacterial species, including strains resistant to other antimicrobial classes. Copyright © 2014 Elsevier Inc.

    The activity of ceftazidime/avibactam and comparator agents was monitored at 73 medical centres across all nine US census bureau regions during 2012. Bacterial isolates were collected from patients hospitalized with pneumonia, urinary tract infections (UTI), intra-abdominal infections (IAI) and bloodstream infections (BSI). The study protocol predetermined the target numbers of strains for each of the requested bacterial species that sites were to collect. Isolates were determined to be clinically relevant at the medical centre and only one isolate per patient episode was collected. There were 1466 Gram-negative isolates from BSI, 3245 from pneumonia patients, 501 from IAI and 2356 from UTI. Ceftazidime/avibactam was active against Enterobacteriaceae from each infection type. The MIC90 values for ceftazidime/avibactam against Enterobacteriaceae isolates from BSI, pneumonia patients, IAI or UTI were 0.25 mg/L. The extended-spectrum cephalosporin resistance rates for Escherichia coli were 8.5% (UTI), 10.4% (IAI), 12.7% (BSI) and 17.5% (pneumonia patients). The extended-spectrum cephalosporin resistance rates for Klebsiella spp. were 13.0% (UTI), 13.9% (BSI), 16.3% (IAI) and 19.3% (pneumonia patients). A total of 96.5% of the Pseudomonas aeruginosa isolates from BSI, 95.8% from pneumonia patients, 96.3% from IAI and 98.7% from UTI exhibited a ceftazidime/avibactam MIC of ≤8 mg/L (CLSI susceptible breakpoint for ceftazidime when tested alone against P. aeruginosa). Most tested agents showed limited activity against Acinetobacter baumannii, except for colistin. A total of 31.2% of A. baumannii displayed ceftazidime/avibactam MIC values of ≤8 mg/L. Ceftazidime/avibactam demonstrated potent broad-spectrum activity against Gram-negative pathogens collected in the USA during 2012 from BSI, pneumonia patients, IAI and UTI. © The Author 2014.

    Tigecycline is approved for the treatment of complicated skin and soft-tissue infections (cSSTIs) and complicated intra-abdominal infections (cIAIs) in adults. In this analysis the safety and tolerability profile of tigecycline (used alone or in combination) for the treatment of patients with approved indications of cSSTI and cIAI were examined under real-life clinical conditions. Individual patient-level data were pooled from five European observational studies (July 2006 to October 2011). A total of 254 cSSTI and 785 cIAI patients were included. The mean age was 63 years; 34.4% and 56.6% were in intensive care units, 90.9% and 88.1% had at least one comorbidity and mean Acute Physiology and Chronic Health Evaluation (APACHE) II scores at the beginning of treatment were 15.0 ± 7.9 and 16.9 ± 7.6, respectively. Data on adverse events (AEs) were available for 198 cSSTI and 590 cIAI patients in three studies. Nausea and vomiting were reported in ≤ 2% of patients. The most common serious AEs were multi-organ failure (4.0% and 10.0% in cSSTI and cIAI patients, respectively) and sepsis (4.0% and 6.1%, respectively). Death was recorded for 24/254 (9.4%) cSSTI and 147/785 (18.7%) cIAI patients. Mortality rates were higher in the group with a baseline APACHE II score of >15 compared with those with a score of ≤ 15 (18.7% versus 3.5% for cSSTI patients and 23.8% versus 16.0% for cIAI patients). A similar trend was seen when cIAI patients were stratified by Sequential Organ Failure Assessment (SOFA) score. The safety and tolerability of tigecycline, alone and in combination, are consistent with the level of critical illness among patients in these real-life studies.

    Purpose: To compare three-dimensional conformal proton radiotherapy (3DCPT), intensity-modulated photon radiotherapy (IMRT), and 3D conformal photon radiotherapy (3DCRT) to predict the optimal RT technique for retroperitoneal sarcomas. Methods and Materials: 3DCRT, IMRT, and 3DCPT plans were created for treating eight patients with retroperitoneal or intra-abdominal sarcomas. The clinical target volume (CTV) included the gross tumor plus a 2-cm margin, limited by bone and intact fascial planes. For photon plans, the planning target volume (PTV) included a uniform expansion of 5 mm. For the proton plans, the PTV was nonuniform and beam-specific. The prescription dose was 50.4 Gy/Cobalt gray equivalent CGE. Plans were normalized so that >95% of the CTV received 100% of the dose. Results: The CTV was covered adequately by all techniques. The median conformity index was 0.69 for 3DCPT, 0.75 for IMRT, and 0.51 for 3DCRT. The median inhomogeneity coefficient was 0.062 for 3DCPT, 0.066 for IMRT, and 0.073 for 3DCRT. The bowel median volume receiving 15 Gy (V15) was 16.4% for 3DCPT, 52.2% for IMRT, and 66.1% for 3DCRT. The bowel median V45 was 6.3% for 3DCPT, 4.7% for IMRT, and 15.6% for 3DCRT. The median ipsilateral mean kidney dose was 22.5 CGE for 3DCPT, 34.1 Gy for IMRT, and 37.8 Gy for 3DCRT. The median contralateral mean kidney dose was 0 CGE for 3DCPT, 6.4 Gy for IMRT, and 11 Gy for 3DCRT. The median contralateral kidney V5 was 0% for 3DCPT, 49.9% for IMRT, and 99.7% for 3DCRT. Regardless of technique, the median mean liver dose was <30 Gy, and the median cord V50 was 0%. The median integral dose was 126 J for 3DCPT, 400 J for IMRT, and 432 J for 3DCRT. Conclusions: IMRT and 3DCPT result in plans that are more conformal and homogenous than 3DCRT. Based on Quantitative Analysis of Normal Tissue Effects in Clinic benchmarks, the dosimetric advantage of proton therapy may be less gastrointestinal and genitourinary toxicity.

    Anastomotic leak is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. We hypothesized that the infection-induced inflammatory response may induce overexpression of tumour progression-related genes in immune cells. The aim was to investigate the effect of postoperative intra-abdominal infection on the gene expression patterns of peripheral blood leucocytes (PBL) after surgery for colorectal cancer. Prospective matched cohort study. Patients undergoing surgery for colorectal cancer were included. Patients who had anastomotic leak or intra-abdominal abscess were included in the infection group (n = 23) and matched with patients without complications for the control group (n = 23). PBL were isolated from postoperative blood samples. Total RNA was extracted and hybridized to the Affymetrix Human Gene 1.0 ST microarray. Patients in the infection group displayed 162 upregulated genes and 146 downregulated genes with respect to the control group. Upregulated genes included examples coding for secreted cytokines involved in tumour growth and invasion (S100P, HGF, MMP8, MMP9, PDGFC, IL1R2). Infection also upregulated some proangiogenic genes (CEP55, TRPS1) and downregulated some inhibitors of angiogenesis (MME, ALOX15, CXCL10). Finally, some inhibitors (HP, ORM1, OLFM4, IRAK3) and activators (GNLY, PRF1, FGFBP2) of antitumour immunity were upregulated and downregulated, respectively, suggesting that the inflammatory environment caused by a postoperative infection favours immune evasion mechanisms of the tumour. Analysis of PBL shows differential expression of certain tumour progression-related genes in colorectal cancer patients who have a postoperative intra-abdominal infection, which in turn may promote the growth of residual cancer cells to become recurrent tumours.

    Late postoperative intra-abdominal infections after laparoscopic gastric banding are extremely rare and may or may not be associated with the device following uncomplicated adjustable gastric banding procedures. The spectrum of pathogens associated with intra-abdominal infections is diverse and depends on the origin of the infection. Streptococci is a significant cause of peritoneal dialysis peritonitis (6% to 16% of the cases), and S. viridans is reported to account for up to 93% of streptococci infections. However, peritonitis due to S. viridans in patients following adjustable gastric banding is very rare. We herein report a non-uremic case of a 38-year-old male patient with severe peritonitis due to S. viridans 5 years after an uneventful primary gastric banding procedure.

    Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) have detrimental effects on all organ systems and are associated with increased morbidity and mortality in critically ill patients admitted to an intensive care unit. Intra-bladder measurement of the intra-abdominal pressure (IAP) is currently the gold standard. However, IAH is not always indicative of intestinal ischemia, which is an early and rapidly developing complication. Sensitive biomarkers for intestinal ischemia are needed to be able to intervene before damage becomes irreversible. Gut wall integrity loss, including epithelial cell disruption and tight junctions breakdown, is an early event in intestinal damage. Intestinal Fatty Acid Binding Protein (I-FABP) is excreted in urine and blood specifically from damaged intestinal epithelial cells. Claudin-3 is a specific protein which is excreted in urine following disruption of intercellular tight junctions. This study aims to investigate if I-FABP and Claudin-3 can be used as a diagnostic tool for identifying patients at risk for IAP-related complications. In a multicenter, prospective cohort study 200 adult patients admitted to the intensive care unit with at least two risk factors for IAH as defined by the World Society of the Abdominal Compartment Syndrome (WSACS) will be included. Patients in whom an intra-bladder IAP measurement is contra-indicated or impossible and patients with inflammatory bowel diseases that may affect I-FABP levels will be excluded. The IAP will be measured using an intra-bladder technique. During the subsequent 72 hours, the IAP measurement will be repeated every six hours. At these time points, a urine and serum sample will be collected for measurement of I-FABP and Claudin-3 levels. Clinical outcome of patients during their stay at the intensive care unit will be monitored using the Sequential Organ Failure Assessment (SOFA) score. Successful completion of this trial will provide evidence on the eventual

    The Study for Monitoring Antimicrobial Resistance Trends (SMART) follows trends in resistance among aerobic and facultative anaerobic gram-negative bacilli (GNB) isolated from complicated intra-abdominal infections (cIAIs) in patients around the world. During 2004-2009, three centralized clinical microbiology laboratories serving 59 private hospitals in three large South African cities collected 1,218 GNB from complicated intra-abdominal infections (cIAIs) and tested them for susceptibility to 12 antibiotics according to the 2011 Clinical Laboratory Standards Institute (CLSI) guidelines. Enterobacteriaceae comprised 83.7% of the isolates. Escherichia coli was the species isolated most commonly (46.4%), and 7.6% of these were extended-spectrum β-lactamase (ESBL)-positive. The highest ESBL rate was documented for Klebsiella pneumoniae (41.2%). Overall, ertapenem was the antibiotic most active against susceptible species for which it has breakpoints (94.6%) followed by amikacin (91.9%), piperacillin-tazobactam (89.3%), and imipenem-cilastatin (87.1%), whereas rates of resistance to ceftriaxone, cefotaxime, ciprofloxacin, and levofloxacin were documented to be 29.7%, 28.7%, 22.5%, and 21.1%, respectively. Multi-drug resistance (MDR), defined as resistance to three or more antibiotic classes, was significantly more common in K. pneumoniae (27.9%) than in E. coli (4.9%; p<0.0001) or Proteus mirabilis (4.1%; p<0.05). Applying the new CLSI breakpoints for carbapenems, susceptibility to ertapenem was reduced significantly in ESBL-positive E. coli compared with ESBL-negative isolates (91% vs. 98%; p<0.05), but this did not apply to imipenem-cilastatin (95% vs. 99%; p=0.0928). A large disparity between imipenem-cilastatin and ertapenem susceptibility in P. mirabilis and Morganella morganii was documented (24% vs. 96% and 15% vs. 92%, respectively), as most isolates of these two species had imipenem-cilastatin minimum inhibitory concentrations in the 2-4 mcg/mL range, which

    The aims of this study were to reveal how using the antibiotics recommended by the 2010 Surgical Infection Society (SIS) and Infectious Disease Society of America (IDSA) guidelines can affect the therapeutic outcomes. We reviewed the cases of 53 patients with a postoperative intra-abdominal abscess without anastomotic leakage after gastrointestinal surgery who underwent image-guided percutaneous abscess drainage (PAD) and concomitant antibiotic therapy. The type of antibiotic initially administered was determined based on the surgeon's judgment. A persistent abscess was defined as one or more PAD procedures resulting in complete resolution after 21 or more days. The recommended antibiotics were defined according to 2010 SIS/IDSA guidelines. All 53 patients had complete resolution without the need for surgery. The results of a multivariable analysis revealed that a C-reactive protein level ≥12 mg/dL and non-recommended antibiotics were significant risk factors for a persistent abscess (P = 0.042 and 0.013, respectively). With regard to a fever lasting more than 48 h, there was a significant difference between the recommended (45.1%) and non-recommended (72.7 %) antibiotic groups (P = 0.046). Using the recommended antibiotics may shorten the time to defervescence and reduce the risk of a persistent abscess in patients undergoing PAD for a postoperative abscess after gastrointestinal surgery.

    The intestinal barrier properties are impaired during inflammation and sepsis, but the mechanisms behind this are unknown and were therefore investigated during experimental sepsis in rats. The different-sized intestinal absorption markers 51 Cr-labeled ethylenediaminetetraacetic acid (EDTA) and ovalbumin were gavaged to rats made septic by intra-abdominal bacterial implantation and to sham-operated rats. Regional tissue permeability was measured in diffusion chambers, and intestinal transit was evaluated by intestinal accumulation of gavaged 51 Cr-EDTA. In comparison with the sham-operated rats, septic rats had higher 51 Cr-EDTA levels in blood and urine and showed a prolonged intestinal transit. Septic rats also had a lower tissue permeability to both markers in the small intestines but higher permeability to ovalbumin in the colon. Rats receiving morphine to decrease intestinal motility showed similar changes, with a decreased intestinal transit and increased marker absorption. Thr results suggest that the increased intestinal absorption during sepsis was due to regional permeability changes and prolonged intestinal transit. 38 refs., 4 figs., 2 tabs

    A non-invasive diagnostic technique for abdominal adhesions is not currently available. Capture of abdominal motion due to respiration in cine-MRI has shown promise, but is difficult to interpret. This article explores the value of a complimentary diagnostic aid to facilitate the non-invasive detection of abdominal adhesions using cine-MRI. An image processing technique was developed to quantify the amount of sliding that occurs between the organs of the abdomen and the abdominal wall in sagittal cine-MRI slices. The technique produces a 'sheargram' which depicts the amount of sliding which has occurred over 1-3 respiratory cycles. A retrospective cohort of 52 patients, scanned for suspected adhesions, made 281 cine-MRI sagittal slices available for processing. The resulting sheargrams were reported by two operators and compared to expert clinical judgement of the cine-MRI scans. The sheargram matched clinical judgement in 84% of all sagittal slices and 93-96% of positive adhesions were identified on the sheargram. The sheargram displayed a slight skew towards sensitivity over specificity, with a high positive adhesion detection rate but at the expense of false positives. Good correlation between sheargram and absence/presence of inferred adhesions indicates quantification of sliding motion has potential to aid adhesion detection in cine-MRI. Advances in Knowledge: This is the first attempt to clinically evaluate a novel image processing technique quantifying the sliding motion of the abdominal contents against the abdominal wall. The results of this pilot study reveal its potential as a diagnostic aid for detection of abdominal adhesions.

    An increase in intra-abdominal fat area (IAFA) is an essential component of metabolic syndrome (MetS). Waist circumference (WC) is not a precise measure of IAFA, and computed tomography (CT) is unsuitable for frequent monitoring. Here, we examined utility of a dual bioelectrical impedance analysis (Dual BIA) for measuring IAFA in obese patients during weight reduction. Fat distribution was measured by Dual BIA and CT in 100 obese outpatients. All fat areas including total, IAFA, and subcutaneous fat by Dual BIA were more closely correlated with those by CT than WC. Estimated IAFA by Dual BIA was significantly correlated with number of MetS components as well as CT, but WC was not. Furthermore, in 61 obese patients who received 6-month weight reduction therapy, estimated IAFA by Dual BIA showed an earlier and greater decrease as well as that by CT than WC and BMI. In addition, decrease in estimated IAFA by Dual BIA through weight reduction had a higher correlation with decrease in IAFA by CT, than WC. This study is the first to demonstrate that the change in estimated IAFA by Dual BIA was highly correlated with that in IAFA by CT during weight reduction therapy. Our findings also indicate that estimated IAFA by Dual BIA is, potentially, a better indicator of severity of MetS, cardiovascular risk factors, and effectiveness of weight reduction than WC, and equal to IAFA by CT. Estimated IAFA by Dual BIA may be useful for monitoring the effectiveness of weight reduction therapy in obese patients.

    The objective of this study was to investigate the distribution and susceptibility of aerobic and facultative Gram-negative bacilli (GNB) isolated from patients with intra-abdominal infections (IAIs) in China. From 2002 to 2009, minimum inhibitory concentrations of 14 antibiotics for 3420 aerobic and facultative GNB from up to eight hospitals in six cities were determined by the broth microdilution method. Enterobacteriaceae comprised 82.9% (2834/3420) of the total isolates, with Escherichia coli (49.2%) being the most commonly isolated species followed by Klebsiella pneumoniae (17.0%), Enterobacter cloacae (5.8%) and Citrobacter freundii (2.3%). Amongst the antimicrobial agents tested, the three carbapenems (ertapenem, imipenem and meropenem) were the most active agents against Enterobacteriaceae, with susceptibility rates of 96.1-99.6% (2002-2009), 98.2-100% (2002-2009) and 99.6-100% (2002-2004), respectively, followed by amikacin (86.8-95.1%) and piperacillin/tazobactam (84.5-94.3%). Susceptibility rates of all tested third- and fourth-generation cephalosporins against Enterobacteriaceae declined by nearly 30%, with susceptibility rates of 40.2%, 39.1%, 56.3% and 51.8% in 2009 for ceftriaxone, cefotaxime, ceftazidime and cefepime, respectively. The occurrence of extended-spectrum β-lactamases increased rapidly, especially for E. coli (from 20.8% in 2002 to 64.9% in 2009). Susceptibility of E. coli to ciprofloxacin decreased from 57.6% in 2002 to 24.2% in 2009. The least active agent against Enterobacteriaceae was ampicillin/sulbactam (SAM) (25.3-44.3%). In conclusion, Enterobacteriaceae were the major pathogens causing IAIs, and carbapenems retained the highest susceptibility rates over the 8-year study period. Third- and fourth-generation cephalosporins, fluoroquinolones and SAM may not be ideal choices for empirical therapy of IAIs in China.

    Chronic inflammatory effects of single intratracheal instillation (i.t.) of quartz on rat lung tumorigenesis were examined using 4 different animal models. At first, in order to determine an appropriate dose of quartz i.t. to promote lung tumorigenesis, F344 male rats were administrated single 0, 0.5, 1, 2 or 4 mg quartz/rat after initiation by N-bis(2-hydroxypropyl) nitrosamine (DHPN). Further studies were performed to examine strain differences of the effects of chronic inflammation caused by quartz i.t. in 3 strains of rat, i.e. F344, Wistar-Hannover and SD. Each was instilled with 2mg quartz/rat after DHPN administration and sacrificed in week 24. In addition, strain differences in generation of inflammation were determined at days 1 and 28. Finally, for determination of long-term effects period, F344 and Wistar-Hannover rats were similarly treated, but the experiment was terminated at week 52. In F344 rats, the tumor areas in DHPN treated groups showed a tendency to increase along with the dose of quartz. F344 rats demonstrated the highest and Wistar-Hannover rats the lowest sensitivity to quartz in acute and chronic phases in the 3 strains. In 52 week, in F344 rats, the multiplicity of tumors and the serum concentration of IL-6 in the group treated with DHPN and quartz were significantly increased. The present experiments indicated that chronic inflammation due to quartz instillation exerted promoting effects on lung carcinogenesis in F344, SD and Wistar-Hannover rats. The strain differences in tumor promotion appeared to correlate with inflammatory reactions to quartz and increase of IL-6. Copyright © 2014 Elsevier GmbH. All rights reserved.

    We aimed to evaluate oxidative stress [8-hydroxydeoxyguanosine (8-OHdG), malondialdehyde (MDA)] endothelial damage [asymmetric dimethylarginine (ADMA)] and markers of cellular inflammation [interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-α), neopterin (NP) and high-sensitivity C-reactive protein (hsCRP)] in patients with diabetic nephropathy (DN) and non-diabetic nephropathy who were being administered hemodialysis treatment because of chronic renal failure. In determining 8-OHdG, IL-6 and TNF-α levels, Enzyme-Linked Immuno-Sorbent Assay method was used. Serum MDA, ADMA and NP levels were determined by using high performance liquid chromatography (HPLC). And hs-CRP values were measured with nephelometric method. Serum 8-OHdG and MDA levels were found statistically to have increased when compared with those of the control group in patients groups after dialysis. However, serum ADMA and neopterin levels were observed statistically to have decreased when compared with those of the control group in patients groups after dialysis. But, decreases on ADMA and neopterin levels are still much higher than those of control. IL-6 and TNF-α levels were found to have increased when compared with those of control group in patients groups before dialysis. The oxidative stress in patients with DN, who were being treated with hemodialysis due to chronic renal failure, was higher than that of non-DN patients who were being treated with hemodialysis. In contrast with this, inflammation occurring in non-DN patients was found to have been higher than that of in patients with DN.

  8. A case of gastrointestinal bleeding due to right hepatic artery pseudoaneurysm following total remnant pancreatectomy: A case report

    Directory of Open Access Journals (Sweden)

    Atsushi Fujio

    Full Text Available Introduction: Pseudoaneurysm is a serious complication after pancreatic surgery, which mainly depends on the presence of a preceding pancreatic fistula. Postpancreatectomy hemorrhage following total pancreatectomy is a rare complication due to the absence of a pancreatic fistula. Here we report an unusual case of massive gastrointestinal bleeding due to right hepatic artery (RHA pseudoaneurysm following total remnant pancreatectomy. Presentation of case: A 75-year-old man was diagnosed with intraductal papillary mucinous carcinoma recurrence following distal pancreatectomy and underwent total remnant pancreatectomy. After discharge, he was readmitted to our hospital with melena because of the diagnosis of gastrointestinal bleeding. Gastrointestinal endoscopy was performed to detect the origin of bleeding, but an obvious bleeding point could not be detected. Abdominal computed tomography demonstrated an expansive growth, which indicated RHA pseudoaneurysm. Emergency angiography revealed gastrointestinal bleeding into the jejunum from the ruptured RHA pseudoaneurysm. Transcatheter arterial embolization was performed; subsequently, bleeding was successfully stopped for a short duration. Because of improvements in his general condition, the patient was discharged. Discussion: To date, very few cases have described postpancreatectomy hemorrhage following total remnant pancreatectomy. We suspect that the aneurysm ruptured into the jejunum, possibly because of the scarring and inflammation associated with his two complex surgeries. Conclusion: Pseudoaneurysm should be considered when the fragility of blood vessels is suspected, despite no history of anastomotic leak and intra-abdominal abscess. Our case also highlighted that detecting gastrointestinal bleeding is necessary to recognize sentinel bleeding if the origin of bleeding is undetectable.

    Full Text Available Abstract Background Worldwide, approximately two billion people are chronically infected with Toxoplasma gondii with largely unknown consequences. Methods To better understand long-term effects and pathogenesis of this common, persistent brain infection, mice were infected at a time in human years equivalent to early to mid adulthood and studied 5–12 months later. Appearance, behavior, neurologic function and brain MRIs were studied. Additional analyses of pathogenesis included: correlation of brain weight and neurologic findings; histopathology focusing on brain regions; full genome microarrays; immunohistochemistry characterizing inflammatory cells; determination of presence of tachyzoites and bradyzoites; electron microscopy; and study of markers of inflammation in serum. Histopathology in genetically resistant mice and cytokine and NRAMP knockout mice, effects of inoculation of isolated parasites, and treatment with sulfadiazine or αPD1 ligand were studied. Results Twelve months after infection, a time equivalent to middle to early elderly ages, mice had behavioral and neurological deficits, and brain MRIs showed mild to moderate ventricular dilatation. Lower brain weight correlated with greater magnitude of neurologic abnormalities and inflammation. Full genome microarrays of brains reflected inflammation causing neuronal damage (Gfap, effects on host cell protein processing (ubiquitin ligase, synapse remodeling (Complement 1q, and also increased expression of PD-1L (a ligand that allows persistent LCMV brain infection and CD 36 (a fatty acid translocase and oxidized LDL receptor that mediates innate immune response to beta amyloid which is associated with pro-inflammation in Alzheimer's disease.

    Lewis (LEW) and Fischer (FIS) inbred rats were used to study the relationship of hypothalamic-pituitary-adrenal (HPA) axis reactivity with inflammation-related pain behavior. LEW rats are susceptible to the development of autoimmune and chronic inflammatory disorders, whereas FIS rats are resistant. Since contradictory data have previously been collected under conditions of acute inflammation, we investigated the onset and maintenance of thermal and mechanical hyperalgesia and spinal activation of neurons and glia cells in a model of ongoing inflammation in both strains. Hind paw volumes and mechanical and thermal pain thresholds were measured prior to and during one week after intraplantar injection of carrageenan. The activation of nociceptive neurons (FosB), astroglia (GFAP) and microglia (OX-42) in the spinal cord of segments L5/L6 was assessed using immunohistochemistry. Inflammation increased paw volume, pain sensitivity and cell activation in both strains. FIS rats were more sensitive to sensory stimulation and developed a more severe edema on day 1, but recovered faster up to day 7 than LEW rats. At that time a higher amount of activated nociceptive neurons and corticosterone was seen in FIS rats, but microglial activation was more pronounced in LEW rats. Our results suggest a biphasic role of the HPA axis in pain behavior and spinal cell activation associated with ongoing inflammation. In the acute stage, the stronger reaction in FIS rats might be explained by an activating effect of corticosteroids on neutrophil function. Under ongoing inflammatory conditions the immunosuppressive actions of corticosteroids may dominate and lead to a quicker recovery of paw volume and pain sensitivity in FIS rats.

Indirect calorimetry showed that the OP rats had higher respiratory exchange ratio (RER) compared to OR rats indicating an impaired ability to oxidize fat. The OP rats had lower expression of carnitine palmitoyltransferase 1b in intra-abdominal fat...... to ghrelin's orexigenic effects as well as ghrelin-induced attenuation of activity and energy expenditure. Thus, increased fat accumulation characterizing obesity may be caused by impaired oxidative capacity due to decreased carnitine palmitoyltransferase 1b levels in the white adipose tissue, while ghrelin...

    It was the objective of this study to assess the effect of the implementation of the smoke-free legislation on haemostasis and systemic inflammation in second-hand smoking (SHS)-exposed healthy volunteers. Fibrin-rich clot properties, platelet reactivity and inflammatory biomarkers were measured before and four months following the implementation of the smoke-free legislation in gender and age-matched healthy volunteers exposed (n=23, exposed) and unexposed (n=23, controls) to occupational SHS. The primary objective was to compare fibrin-rich clot stiffness before and after implementation of the smoke-free legislation. There was 40% reduction in fibrin-rich clot stiffness following the implementation of the smoke-free legislation in SHS-exposed volunteers (17 ± 7 vs. 10.6 ± 7 dynes/cm², before and after, respectively, p=0.001). These dramatic changes were associated with a 20% reduction in fibrin fiber density (plegislation. Of interest, neither platelet reactivity nor systemic inflammatory biomarkers were changed in either group. The smoke-free legislation is associated with significant changes in fibrin-rich clot properties toward a less thrombogenic conformation with a better fibrinolysis response while neither platelet reactivity nor systemic inflammatory biomarkers are modified. These improvements may explain the observed reduction in acute coronary syndrome following the implementation of the smoke-free legislation.

    Discussion was made of antitussive effects of Eprazinone hydrochloride (Resplen) on radiation induced inflammation of the upper respiratory tract in 15 cases irradiated after an operation of breast cancer. Depth dose at 3 cm was 200 rads/day, and 5000 rad/25 times/5 weeks was irradiated with telecobalt. Mainly abnormal sensation and pain in the throat and cough appeared and patients complained of suffering from a common cold, because a part of irradiation field included the throat, trachea, and esophagus. At the same time as manifestation of symptoms, 120 mg/day of Eprazinone Dihydrochloride was administered. In 8 cases, other drugs were added to, or irradiation schedule was changed because the symptoms were not improved or were exaggerated. The symptoms disappeared up to 5000 rad irradiation in one case, up to 4000 - 5000 rad irradiation in 4 cases, and up to 4000 rad irradiation in 2 cases. It is impossible to decide effective rate of this drug because of shortage of clinical cases, but it is suggested that there is a significance to increase cases treated successively with this drug in future.

    Persistent allergic rhinitis (PER) has a moderate impact on the sense of smell, but no controlled study has reported the effect of antihistamines on the loss of smell in patients with PER. Patients with PER and subjective loss of the sense of smell (n = 27) were included in this pilot randomised, double-blind, placebo-controlled study. Nasal symptoms, nasal endoscopy, skin prick test, acoustic rhinometry, peak nasal inspiratory flow, nasal nitric oxide (nNO), and olfactometry (Barcelona Smell Test-24; BAST-24) were performed and evaluated in all PER patients at baseline and after 7 and 30 days of treatment with levocetirizine 5 mg or placebo. The study population was randomized into two homogeneous groups: levocetirizine (n = 14) and placebo groups (n = 13). The evolution of symptoms reflected the therapeutic effect of levocetirizine treatment on rhinorrhea, nasal itching, eye itching, sneezing, and the total symptoms score after 7 and 30 days. Significant improvement in loss of smell by a visual analog scale (VAS) was observed after 7 days of levocetirizine treatment (7.2 ± 4.3; p smell identification by BAST-24 was strongly correlated (r = 0.72; p smell improvement by VAS after 30 days. After 7 days of treatment with levocetirizine, the nNO values decreased (-494 ± 188) compared to placebo (155 ± 284 ppb; p smell, and that this improvement concurs more with reduction of nasal inflammation than of nasal patency.

    2014-01-01

    We report a case of a 77-year-old female who was admitted to the emergency department complaining of diffuse abdominal pain for five days, associated with nausea, vomiting and constipation. Physical examination disclosed a large incarcerated umbilical hernia, which was readily apparent on supine abdominal plain films. These also showed a calcified heterogeneous mass in the mid-abdominal region, which was further characterized by CT as a lithopedion (calcified ectopic pregnancy). This is one of the few cases studied on a MDCT equipment, and it clearly enhances the post-processing abilities of this imaging method which allows diagnostic high-quality MIP images. Lithopedion is a rare entity, with less than 300 cases previously described in the medical literature. However, many reported cases corresponded to cases of skeletonization or collections of fetal bone fragments discovered encysted in the pelvic region at surgery or autopsy. It is thus estimated that true lithopedion is a much rarer entity. The diagnosis may be reached by a suggestive clinical history and a palpable mass on physical examination, while the value of modern cross-sectional techniques is still virtually unknown. Ultrasonography may depict an empty uterine cavity and a calcified abdominal mass of non-specific characteristics, and computed tomography or magnetic resonance imaging are able to reach a conclusive diagnosis and may additionally define the involvement of adjacent structures. The differential diagnosis includes other calcified pathologic situations, including ovarian tumors, uterine fibroids, urinary tract neoplasms, inflammatory masses or epiploic calcifications

    CT diagnosis of intraabdominal abscess was confirmed in 18 patients by laparatomy and in two by autopsy. In CT abscess is characterized by an expansive soft-tissue lesion with different density values, mostly with a central fluid collection and a thickened wall. The peripheral inflammatory reaction leads to obliteration of fat planes surrounding the adjacent organs. Further symptomes are constrast enhancement of the wall and extraluminal gas collection. The combination of all these signs together with a suitable history and clinical findings allow a reliable diagnosis of abscess formation. When only isolated signs are found, differentiation from tumor, pseudocyst or hematoma may be difficult. (orig.) [de

    The present work deals with the problem of abdominal injuries in polytraumatized patients. The results were obtained from a retrospective study of the records of 530 polytraumatized patients treated at the Central Hospital of the German Federal Armed Forces (Bundeswehr). In all, 193 of these patients had abdominal injuries. The overall mortality was 23.8% (n = 126): mortality among the patients with abdominal injuries was 26% (n = 50). Abdominal injuries alone led to death in 9.1% (n = 1), but mortality increased to 18.4% when at least one extra-abdominal injuries was also present. A combination of abdominal injuries and two or more extra-abdominal lesion led to a mortality rate of 27%. Mortality was found to be age- and sex-related: in young children and patients over 55 years (especially those around 70) mortality was 33.3%-72%. Among the cases with fatal outcome there was a female-to-male ratio of 3:2. The most common causes of death were: hemorrhage shock (62.3%), head injuries (37.7%), septicemia (8.1%), pneumonia, and ARDS (5.4% each). Within the last eight years we have used the following supplementary examination methods: computed tomography, peritoneal lavage, and ultrasonography. The retrospective study has shown that CT is not the examination of choice. The reliability with lavage and ultrasonography was approximately the same, but lavage was found to be more dangerous. Therefore, we abandoned lavage and used sonography only. However, we are of the opinion that any surgeon should use the examination method that has yielded the best results for him or her, to ensure the best possible outcome for the patient.

    Clostridium septicum is an unusual anaerobic, gram-positive, gas-producing bacillus, which has been identified as a cause of fulminant rapidly fatal infection in humans. Infection with C. septicum usually occurs in patients with cancer, patients receiving immunosuppressive chemotherapy, or patients with a nonmalignant hematological disorder such as hemolytic uremic syndrome. C. septicum infection most commonly involves the abdomen, and a recent review article has identified 164 cases in the medical literature describing the abdominal findings in this disease. Intracranial manifestation of C. septicum infection are less common and include meningitis, cerebritis, abscess formation and pneumocephalus. There have been only 12 documented cases in the English literature describing central nervous system lesions associated with C. septicum. We present a case report of a 56-year-old man in whom septicemia due to C. septicum developed as a complication of Crohn's disease. To our knowledge, there has never been a previous report of C. septicum sepsis related to underlying Crohn's disease. Our case is also remarkable in that an intracerebral gas collection developed at the site of a mycotic infarct related to C. septicum bacteremia, Intracranial, intraparenchymal gas formation related to anaerobic infection is extremely rare; to our knowledge, this radiological finding related to C. septicum sepsis has been described in only 1 previous case report in the medical literature. We also describe the intra-abdominal manifestations of C. septicum sepsis that occurred in this patient as well as the associated radiographic and pathologic findings. (author)

    Peritoneal dialysis (PD) is a kidney replacement therapy for end stage renal disease (ESRD) patients. Despite being a lifesaving treatment, the rate of mortality in patients under PD is elevated, mainly due to the chronic peritoneal dysfunction which is characterized by inflammation, peritoneal fibrosis and neoangiogenesis. The inflammatory process is trigged and modulated by the type of the peritoneal dialysis solutions (PDSs) used during PD. Currently, different PDSs are commercially available: (i) the conventional solutions; (ii) solutions of neutral pH containing low concentration of glucose degradation products (GDPs); (iii) solutions with icodextrin; and (iv) solutions containing taurine. Therefore, the aim of this review is to describe the different types of peritoneal dialysis solutions used during PD and their relationship with systemic and intraperitoneal inflammation. Some studies suggested that solutions of neutral pH containing low concentration of GDPs, icodextrin and taurine have better biocompatibility and lower influence on the inflammatory process compared to the conventional one. On the other hand, the studies, in general, were performed with a small population and for a short period of time. Therefore, further well-designed and -controlled clinical trials with larger number of individuals are required in order to better understand the role of different peritoneal dialysis solution types in the development of inflammation in patients with chronic peritoneal dialysis. Accordingly, studies that are more well-designed, well-controlled and with a larger number of patients are needed to explain and define the role of different types of PDS in the inflammation development in patients with chronic peritoneal dialysis.

    The participation of inflammation in the progression of cancer for many years have been the subject of research. In the 19th century, there was evidence that an acute inflammation may inhibit the development of cancer. However, chronic inflammation affects the progression of the disease. Today, it is known that inflammation and cancer use similar mechanisms of development such as severe cell proliferation or angiogenesis. It has been shown that prolonged presence of inflammatory cells and factors in the tumor microenvironment can accelerate its growth and inhibit apoptosis of transformed cells. In this article we present a brief history of the discovery mechanisms and potential links between acute and chronic inflammation and cancer.

    Medical Infrared Thermography (MIT) offers a potential non-invasive, non-contact and radiation free imaging modality for assessment of abnormal inflammation having pain in the human body. The assessment of inflammation mainly depends on the emission of heat from the skin surface. Arthritis is a disease of joint damage that generates inflammation in one or more anatomical joints of the body. Osteoarthritis (OA) is the most frequent appearing form of arthritis, and rheumatoid arthritis (RA) is the most threatening form of them. In this study, the inflammatory analysis has been performed on the infrared images of patients suffering from RA and OA. For the analysis, a dataset of 30 bilateral knee thermograms has been captured from the patient of RA and OA by following a thermogram acquisition standard. The thermograms are pre-processed, and areas of interest are extracted for further processing. The investigation of the spread of inflammation is performed along with the statistical analysis of the pre-processed thermograms. The objectives of the study include: i) Generation of a novel thermogram acquisition standard for inflammatory pain disease ii) Analysis of the spread of the inflammation related to RA and OA using K-means clustering. iii) First and second order statistical analysis of pre-processed thermograms. The conclusion reflects that, in most of the cases, RA oriented inflammation affects bilateral knees whereas inflammation related to OA present in the unilateral knee. Also due to the spread of inflammation in OA, contralateral asymmetries are detected through the statistical analysis.

    Most infants are immunologically active and are able to develop a tolerance to oligoclonal antigens by producing IgA, along with activation of regulatory T cells, in early infancy. Cytokines and their signaling molecules are important mediators in the intestine, regulating both oral tolerance and mucosal inflammation. This system works efficiently in most individuals, but for an as yet undefined reason, some people react to food and other proteins as though they were pathogens, with induction of chronic inflammation in the mucosa. The adverse reaction caused by ingested foods is defined as food intolerance. The clinical features of food intolerance include vomiting, diarrhea, bloody stool, eczema, failure to thrive, and a protean range of other symptoms. Intolerance can be divided into two categories depending on whether or not they are immunologically mediated. Food intolerance and mucosal inflammation are deeply related because tolerance cannot be established when there is an inflammation in the intestinal mucosa. Mast cells, eosinophils, mucosal lymphocytes, and epithelial cells are deeply involved and related to each other in the development of mucosal inflammation. Meanwhile, rectal bleeding in infancy is related to lymphoid hyperplasia with eosinophil infiltration into the colonic mucosa facilitated by C-C motif ligand 11 (CCL11, known as eotaxin-1) and C-X-C motif chemokine ligand 13 (CXCL13). Rectal bleeding in infancy may not be simply caused by allergic reactions against specific antigens, but may be due to migrated lymphocytes developing immunological tolerance; including IgA synthesizing, in the intestinal mucosa. © 2014 Japan Pediatric Society.

    Helicobacter pylori infection leads to long-lasting chronic inflammation and represents the most common risk factor underlying gastric cancer. Recently, new insights into the mechanisms through which H. pylori and mucosal inflammation lead to cancer development have emerged. H. pylori virulence factors, in particular specific CagA genotypes, represent main factors in gastric cancer, inducing altered intracellular signaling in epithelial cells. The chronic nature of H. pylori infection appears to relate to the VacA virulence factor and Th17/Treg mechanisms. A role of H. pylori infection in epigenetic and microRNA deregulation has been shown. Mutation of the epithelial cell genome, a hallmark of cancer, was demonstrated to accumulate in H. pylori infected stomach partly due to inadequate DNA repair. Gastric stem cells were shown to be targets of oxidative injury in the Helicobacter-inflammatory milieu. Recent advances emphasizing the contribution of bacterial factors, inflammatory mediators, and the host epithelial response in gastric carcinogenesis are reviewed.

    2016-01-01

    Sites of inflammation are defined by significant changes in metabolic activity. Recent studies have suggested that O2 metabolism and hypoxia play a prominent role in inflammation so-called “inflammatory hypoxia,” which results from a combination of recruited inflammatory cells (e.g., neutrophils and monocytes), the local proliferation of multiple cell types, and the activation of multiple O2-consuming enzymes during inflammation. These shifts in energy supply and demand result in localized regions of hypoxia and have revealed the important function off the transcription factor HIF (hypoxia-inducible factor) in the regulation of key target genes that promote inflammatory resolution. Analysis of these pathways has provided multiple opportunities for understanding basic mechanisms of inflammation and has defined new targets for intervention. Here, we review recent work addressing tissue hypoxia and metabolic control of inflammation and immunity. PMID:27193451

    Full Text Available BACKGROUND: Infectious diseases are among the major causes of death worldwide. We evaluated the trends of mortality due to septicemia in Greece and compared it with mortality due to other infections. METHODS: Data on mortality stratified by cause of death during 2003-2010 was obtained from the Hellenic Statistical Authority. Deaths caused by infectious diseases were grouped by site of infection and analyzed using SPSS 17.0 software. RESULTS: 45,451 deaths due to infections were recorded in Greece during the 8-year period of time, among which 12.2% were due to septicemia, 69.7% pneumonia, 1.5% pulmonary tuberculosis, 0.2% influenza, 0.5% other infections of the respiratory tract, 7.9% intra-abdominal infections (IAIs, 2.5% urinary tract infections (UTIs, 2.2% endocarditis or pericarditis or myocarditis, 1.6% hepatitis, 1% infections of the central nervous system, and 0.7% other infections. A percentage of 99.4% of deaths due to septicemia were caused by bacteria that were not reported on the death certificate (noted as indeterminate septicemia. More deaths due to indeterminate septicemia were observed during 2007-2010 compared to 2003-2006 (3,558 versus 1,966; p<0.05. CONCLUSION: Despite the limitations related to the quality of death certificates, this study shows that the mortality rate due to septicemia has almost doubled after 2007 in Greece. Proportionally, septicemia accounted for a greater increase in the mortality rate within the infectious causes of death for the same period of time. The emergence of resistance could partially explain this alarming phenomenon. Therefore, stricter infection control measures should be urgently applied in all Greek healthcare facilities.

    The Occupational Health and Safety (OHS) Act requires that every employer shall ensure the health and safety of workers in the workplace. Issues regarding the practices at workplaces and how they should reflect the standards of due diligence were discussed. Due diligence was described as being the need for employers to identify hazards in the workplace and to take active steps to prevent workers from potentially dangerous incidents. The paper discussed various aspects of due diligence including policy, training, procedures, measurement and enforcement. The consequences of contravening the OHS Act were also described

    Bronchoalveolar lavage cells and bronchial biopsies were obtained from nine patients with red cedar asthma, six atopic asthmatics and six non-atopic, non-asthmatic control subjects. There were similar proportions of neutrophils, mast cells, lymphocytes, and macrophages in BAL samples from all three groups, but eosinophil numbers were elevated in patients with cedar asthma and atopic asthma (3.0 and 2.5% respectively versus 0.5% in control subjects; p < 0.05 for each group). In bronchial mucosal biopsies, mean numbers of T cells were elevated in both asthmatic groups (cedar asthma 9.8 times, and atopic asthma 2.6 times, control values). CD4+ cells accounted for most of the increase in T-cell numbers, while CD8+ cell numbers were elevated in biopsies from a minority of cedar asthma patients. Absolute numbers of CD25+ (IL-2 receptor-bearing) cells were increased in cedar asthma but the proportion of T cells expressing CD25, was similar in all three groups. Activated eosinophils (EG2+) were increased in both asthmatic groups, with mean numbers 2.5 times greater in the cedar asthma biopsies than in atopic asthmatics. Thus both cedar asthma and atopic asthma are associated with increased numbers of T-cells and activated eosinophils in the bronchial mucosa. There was no major histologic difference between atopic asthma and red cedar asthma.

    This review focuses on the complex relationship between inflammation and the onset of acute coronary syndrome and heart failure. In the last few years, two important lines of research brought new and essential information to light in the pathogenesis of acute coronary syndrome: a) the understanding of the immune mediate mechanisms of inflammation in Ischemic Heart Disease (IHD) and b) evidence that the inflammatory mechanisms associated with atherosclerosis and its complications can be modulated by anti-inflammatory molecules. A large amount of data also suggests that inflammation is a major component in the development and exacerbation of heart failure (HF), in a symbiotic relationship. In particular, recent evidence underlies peculiar aspects of the phenomenon: oxidative stress and autophagy; DAMPS and TLR-4 signaling activation; different macrophages lineage and the contribution of NLRP-3 inflammasome; adaptive immune system. A possible explanation that could unify the pathogenic mechanism of these different conditions is the rising evidence that increased bowel permeability may allow translation of gut microbioma product into the circulation. These findings clearly establish the role of inflammation as the great trigger for two of the major cardiovascular causes of death and morbidity. Further studies are needed, to better clarify the issue and to define more targeted approaches to reduce pathological inflammation while preserving the physiological one.

    Women become depressed more frequently than men, a consistent pattern across cultures. Inflammation plays a key role in initiating depression among a subset of individuals, and depression also has inflammatory consequences. Notably, women experience higher levels of inflammation and greater autoimmune disease risk compared to men. In the current review, we explore the bidirectional relationship between inflammation and depression and describe how this link may be particularly relevant for women. Compared to men, women may be more vulnerable to inflammation-induced mood and behavior changes. For example, transient elevations in inflammation prompt greater feelings of loneliness and social disconnection for women than for men, which can contribute to the onset of depression. Women also appear to be disproportionately affected by several factors that elevate inflammation, including prior depression, somatic symptomatology, interpersonal stressors, childhood adversity, obesity, and physical inactivity. Relationship distress and obesity, both of which elevate depression risk, are also more strongly tied to inflammation for women than for men. Taken together, these findings suggest that women's susceptibility to inflammation and its mood effects may contribute to sex differences in depression. Depression continues to be a leading cause of disability worldwide, with women experiencing greater risk than men. Due to the depression-inflammation connection, these patterns may promote additional health risks for women. Considering the impact of inflammation on women's mental health may foster a better understanding of sex differences in depression, as well as the selection of effective depression treatments.

Furthermore, we present evidence that smoking on its own can cause nasal disease, and that in COPD patients, nasal inflammation mimics that of the bronchi. All...... this evidence suggests that COPD related sinonasal disease does exist and that smoking on its own rather than systemic inflammation triggers the condition.

    Inflammation is a protective response essential for maintaining human health and for fighting disease. As an active innate immune reaction to challenge, inflammation gives rise to clinical cardinal signs: rubor, calor, dolor, tumor and functio laesa. Termination of acute inflammation was previously recognized as a passive process; a natural decay of pro-inflammatory signals. We now understand that the natural resolution of inflammation involves well-integrated, active, biochemical programs that return tissues to homeostasis. This review focuses on recent advances in the understanding of the role of endogenous lipid mediators that modulate cellular fate and inflammation. Biosynthesis of eicosanoids and other lipids in exudates coincides with changes in the types of inflammatory cells. Resolution of inflammation is initiated by an active class switch in lipid mediators, such as classic prostaglandins and leukotrienes, to the production of proresolution mediators. Endogenous pro-resolving lipid mediators, including arachidonic acid-derived lipoxins, aspirin-triggered lipoxins, ω3-eicosapentaenoic acid-derived resolvins of the E-series, docosahexaenoic acid-derived resolvins of the D-series, protectins and maresins, are biosynthesized during the resolution phase of acute inflammation. Depending on the type of injury and the type of tissue, the initial cells that respond are polymorphonuclear leukocytes, monocytes/macrophages, epithelial cells or endothelial cells. The selective interaction of specific lipid mediators with G protein-coupled receptors expressed on innate immune cells (e.g. G protein-coupled receptor 32, lipoxin A4 receptor/formyl peptide receptor2, chemokine-like receptor 1, leukotriene B4 receptor type 1 and cabannoid receptor 2) induces cessation of leukocyte infiltration; vascular permeability/edema returns to normal with polymorphonuclear neutrophil death (mostly via apoptosis), the nonphlogistic infiltration of monocyte/macrophages and the removal

    To determine the effects of raising serum T levels into the high normal female range by transdermal T administration on insulin sensitivity, fat volume, and markers of inflammation and thrombolysis in HIV-infected women with recent weight loss. Placebo-controlled, randomized clinical trial. Academic clinical research center. Fifty-two HIV-infected, menstruating women with >5% weight loss over the prior 6 months and current TTestosterone by liquid chromatography-tandem mass spectrometry, insulin sensitivity by the frequently sampled intravenous glucose tolerance test (FSIVGT), abdominal and thigh fat volumes by magnetic resonance imaging (MRI), and C-reactive protein (CRP) as a measure of inflammation and plasminogen-activated inhibitor-1 (PAI-1) levels as a marker of thrombolysis. Serum and free T levels significantly increased into the high normal female range in T-treated but not placebo-treated women. Insulin sensitivity by FSIVGT, whole body, thigh SC, and intra-abdominal fat volumes, and CRP and PAI-1 levels did not change significantly in either group and were not significantly different between the two groups. Fasting insulin increased in the placebo group and fell slightly in the T group, resulting in significant differences in change between groups. Twenty-four weeks of elevation of serum T levels into the high normal female range in HIV-infected women with mild to moderate weight loss by transdermal T patches did not adversely affect insulin sensitivity, whole-body fat mass or regional fat distribution, or markers of inflammation and thrombolysis. More prolonged and larger studies are needed to determine the effects of higher doses of T on body composition and insulin sensitivity in women.

    The immune system, inflammation and hypertension are related to each other. Innate and adaptive immunity system triggers an inflammatory process, in which blood pressure may increase, stimulating organ damage. Cells in innate immune system produce ROS, such as superoxide and hydrogen peroxide, which aimed at killing pathogens. Long-term inflammation process increases ROS production, causing oxidative stress which leads to endothelial dysfunction. Endothelial function is to regulate blood vessel tone and structure. When inflammation lasts, NO bioavailability decreases, disrupting its main function as vasodilator, so that blood vessels relaxation and vasodilatation are absent. Effector T cells and regulatory lymphocytes, part of the adaptive immune system, plays role in blood vessels constriction in hypertension. Signals from central nervous system and APC activates effector T lymphocyte differentiation and accelerate through Th-1 and Th-17 phenotypes. Th-1 and Th-17 effectors participate in inflammation which leads to increased blood pressure. One part of CD4+ is the regulatory T cells (Tregs) that suppress immune response activation as they produce immunosuppressive cytokines, such as TGF-β and IL-10. Adoptive transfer of Tregs cells can reduce oxidative stress in blood vessels, endothelial dysfunction, infiltration of aortic macrophages and T cells as well as proinflammatory cytokine levels in plasma circulation.

    Glucocorticoids are steroid hormones that once bound to their receptor interact with the DNA binding domain. Almost 1000-2000 genes are sensitive to their effects, including immune/inflammatory response genes. However, their role in pathophysiology and therapy is still debated. We performed a literature survey using the key words glucocorticoids, inflammation, autoimmune disease, rheumatology and adrenal glands in order to define important targets for this review on glucocorticoids. Considering endogenous/exogenous glucocorticoids in chronic inflammatory diseases brought up five major points for discussion: inadequately low production of endogenous cortisol relative to systemic inflammation (the disproportion principle); changes of the systemic and local cortisol-to-cortisone shuttle (reactivation and degradation of cortisol); inflammation-induced glucocorticoid resistance; highlights of present glucocorticoid therapy; and the role of circadian rhythms in action of cortisol. Much of this information becomes understandable in the context of neurohormonal energy regulation as recently summarized. The optimization of long-term low-dose glucocorticoid therapy in chronic inflammatory diseases arises from the understanding of the above mentioned aspects. Since glucocorticoid resistance is a consequence of inflammation, adequate anti-inflammatory therapy is mandatory. © The Author 2016.

    2013-01-01

    Full Text Available Pulmonary sequestration is a congenital abnormality consisting of a mass of pulmonary tissue that presents an abnormal connection with the tracheobronchial tree, with a blood supply coming from an anomalous artery derived from the systemic circulation. Extralobar pulmonary sequestration is characterized by having pleural coverings that are independent of the normal lungs, with vascular supply usually coming from the aorta or from one of its branches. This diagnosis can be suspected prenatally if an abdominal mass, generally below the diaphragm, is seen. Here, we present a case of a neonate on the second day of life, with ultrasonography showing extralobar pulmonary sequestration located above the left adrenal gland that prenatally simulated a neuroblastoma.

    Peritoneal adhesions are fibrous bands of tissues formed between organs that are normally separated and/or between organs and the internal body wall after peritoneal injury. The aim of the study was to investigate the effect of intra-peritoneal administration of Kombucha on intra-peritoneal adhesions. Eighty Wistar rats were subjected to standardized lesion by scraping model and were randomly divided into two groups. Group I received no treatment, and Group II received 15 ml of Kombucha solution intra-peritoneally. On the post-operative 14th day adhesion intensity score, inflammatory cell reaction and number of adhesion bands were determined. In the control group, there were no rats with grade 0 and I adhesions. In the group II, there were 26 rats (78.8%) with grade 0-2 adhesions. Adhesion intensity was significantly less in group II (PKombucha might be useful for preventing peritoneal adhesions.

    Egan, Aoife M

    2012-01-31

    INTRODUCTION: Bilateral adrenal haemorrhage is a rare cause of adrenal failure. Clinical features are non-specific and therefore a high index of suspicion must be maintained in patients at risk. Predisposing factors include infection, malignancy and the post-operative state. CASE PRESENTATION: We report the case of a patient who underwent a left hemicolectomy with primary anastomosis and formation of a defunctioning loop ileostomy for an obstructing colon carcinoma at the splenic flexure. En-bloc splenectomy was performed to ensure an oncologic resection. The patient developed a purulent abdominal collection post-operatively and became septic with hypotension and pyrexia. This precipitated acute bilateral adrenal haemorrhage with consequent adrenal insufficiency. Clinical suspicion was confirmed by radiological findings and a co-syntropin test. Following drainage of the collection, antibiotic therapy and corticosteroid replacement, the patient made an excellent recovery. CONCLUSION: This case highlights the importance of prompt diagnosis and treatment of adrenal failure. In their absence, this condition can rapidly lead to death of the patient.

    1989-01-01

    Since 1986, 32 patients with metastatic colorectal cancer have undergone second-look radioimmunoguided surgery (RIGS system). The primary tumor was located in the right and transverse colon in 11 patients, left and sigmoid colon in 16, and rectum in five. The carcinoembryonic antigen level was elevated in 30 patients (94%); all patients underwent a computed tomographic scan of the abdomen and pelvis. The overall sensitivity of the computed tomographic scan was 41% (abdomen other than liver, 27%; liver, 58%; and pelvis, 22%). The RIGS system identified recurrent tumor in 81% of the patients. The most common site of metastasis was the liver (41%), independent of the primary location. Local/regional recurrences alone accounted for 40% of all recurrences. In six patients (18%), recurrent tumor was found only with the RIGS system. The RIGS system is more dependable in localizing clinically obscure metastases than other methods, and carcinoembryonic antigen testing remains the most accurate preoperative method to indicate suspected recurrences

Blood samples were collected for 14 players and 10 control non-athletes prior to and after the 8-month competitive season. Athletes’ performance was assessed with the NBA efficiency score. At the baseline hepcidin correlated with blood ferritin (r=0.61; 90% CL ±0.31, but at the end of the season this correlation was absent. Compared with the control subjects, athletes experienced clear large increases in hepcidin (50%; 90% CI 15-96% and interleukin-6 (77%; 90% CI 35-131% and a clear small decrease in vitamin D (-12%; 90% CI -20 to -3% at the season completion. Correlations between change scores of these variables were unclear (r = -0.21 to 0.24, 90% CL ±0.5, but their uncertainty generally excluded strong relationships. Athletes were hence concluded to have experienced acute inflammation at the beginning but chronic inflammation at the end of the competitive season. At the same time, the moderate correlation between changes in vitamin D and players’ performance (r=0.43 was suggestive of its beneficial influence. Maintaining the appropriative concentration of vitamin D is thus necessary for basketball players’ performance and efficiency. The assessment of hepcidin has proven to be useful in diagnosing inflammation in response to chronic exercise.

    Full Text Available The 13 kDa heparin-binding growth factor midkine (MK was originally identified as a molecule involved in the orchestration of embryonic development. Recent studies provided evidence for a new role of MK in acute and chronic inflammatory processes. Accordingly, several inflammatory diseases including nephritis, arthritis, atherosclerosis, colitis, and autoimmune encephalitis have been shown to be alleviated in the absence of MK in animal models. Reduced leukocyte recruitment to the sites of inflammation was found to be one important mechanism attenuating chronic inflammation when MK was absent. Furthermore, MK was found to modulate expression of proinflammatory cytokines and the expansion of regulatory T-cells. Here, we review the current understanding of the role of MK in different inflammatory disorders and summarize the knowledge of MK biology.

  4. Dietary Anthocyanins against Obesity and Inflammation

    2017-10-01

    Full Text Available Chronic low-grade inflammation plays a pivotal role in the pathogenesis of obesity, due to its associated chronic diseases such as type II diabetes, cardiovascular diseases, pulmonary diseases and cancer. Thus, targeting inflammation is an attractive strategy to counter the burden of obesity-induced health problems. Recently, food-derived bioactive compounds have been spotlighted as a regulator against various chronic diseases due to their low toxicity, as opposed to drugs that induce severe side effects. Here we describe the beneficial effects of dietary anthocyanins on obesity-induced metabolic disorders and inflammation. Red cabbage microgreen, blueberry, blackcurrant, mulberry, cherry, black elderberry, black soybean, chokeberry and jaboticaba peel contain a variety of anthocyanins including cyanidins, delphinidins, malvidins, pelargonidins, peonidins and petunidins, and have been reported to alter both metabolic markers and inflammatory markers in cells, animals, and humans. This review discusses the interplay between inflammation and obesity, and their subsequent regulation via the use of dietary anthocyanins, suggesting an alternative dietary strategy to ameliorate obesity and obesity associated chronic diseases.

    West syndrome (WS) is an infantile epileptic encephalopathy that manifests with infantile spasms (IS), hypsarrhythmia (in ~60% of infants), and poor neurodevelopmental outcomes. The etiologies of WS can be structural-metabolic pathologies (~60%), genetic (12%-15%), or of unknown origin. The current treatment options include hormonal treatment (adrenocorticotropic hormone and high-dose steroids) and the GABA aminotransferase inhibitor vigabatrin, while ketogenic diet can be given as add-on treatment in refractory IS. There is a need to identify new therapeutic targets and more effective treatments for WS. Theories about the role of inflammatory pathways in the pathogenesis and treatment of WS have emerged, being supported by both clinical and preclinical data from animal models of WS. Ongoing advances in genetics have revealed numerous genes involved in the pathogenesis of WS, including genes directly or indirectly involved in inflammation. Inflammatory pathways also interact with other signaling pathways implicated in WS, such as the neuroendocrine pathway. Furthermore, seizures may also activate proinflammatory pathways raising the possibility that inflammation can be a consequence of seizures and epileptogenic processes. With this targeted review, we plan to discuss the evidence pro and against the following key questions. Does activation of inflammatory pathways in the brain cause epilepsy in WS and does it contribute to the associated comorbidities and progression? Can activation of certain inflammatory pathways be a compensatory or protective event? Are there interactions between inflammation and the neuroendocrine system that contribute to the pathogenesis of WS? Does activation of brain inflammatory signaling pathways contribute to the transition of WS to Lennox-Gastaut syndrome? Are there any lead candidates or unexplored targets for future therapy development for WS targeting inflammation? © 2017 Elsevier Inc. All rights reserved.

    Calcium pyrophosphate dihydrate (CPPD) and basic calcium phosphate (BCP) crystals are common components of osteoarthritic joint fluids and tissues. Why these crystals form and how they contribute to joint damage in osteoarthritis remain unclear. With renewed interest in inflammation as a key component of osteoarthritis the role of calcium-containing crystals in this common disease warrants re-examination. There is ample evidence supporting a pathogenic role for inflammation in osteoarthritis, and the innate immune system likely participates in this inflammatory process. Recent work reinforces the almost universal existence of calcium-containing crystals in tissues from patients with end-stage osteoarthritis. Calcium-containing crystals may contribute to inflammation in osteoarthritis tissues through their direct interactions with components of the innate immune system, as well as by inducing or amplifying other inflammatory signals. There is increasing evidence that calcium-containing crystals contribute to osteoarthritis and their inflammatory properties may mediate detrimental effects through innate immunity signals. Calcium-containing crystals may thus represent important therapeutic targets in osteoarthritis.

    Cytokines of the intestinal microenvironment largely dictate immunological responses after mucosal insults and the dominance of homeostatic or proinflammatory pathways. This review presents important recent studies on the role of specific cytokines in the pathogenesis of intestinal inflammation. The particular mucosal effects of cytokines depend on their inherent properties but also the cellular origin, type of stimulatory antigens, intermolecular interactions, and the particular immunological milieu. Novel cytokines of the interleukin-1 (IL-1) family, including IL-33 and IL-36, have dominant roles in mucosal immunity, whereas more established ones such as IL-18 are constantly enriched with unique properties. Th17 cells are important mucosal constituents, although their profound plasticity, makes the specific set of cytokines they secrete more important than their mere numbers. Finally, various cytokines, such as tumor necrosis factor-α, IL-6, tumor necrosis factor-like cytokine 1A, and death receptor, 3 demonstrate dichotomous roles with mucosa-protective function in acute injury but proinflammatory effects during chronic inflammation. The role of cytokines in mucosal health and disease is increasingly revealed. Such information not only will advance our understanding of the pathogenesis of gut inflammation, but also set the background for development of reliable diagnostic and prognostic biomarkers and cytokine-specific therapies.

    Full Text Available Abstract Background Knowledge of the etiology of pyogenic liver and pancreatic abscesses is an important factor in determining the success of combined surgical and antibiotic treatment. Literature shows geographical variations in the prevalence and distribution of causative organisms, and the spread of Klebsiella pneumoniae carbapenemase-producing bacteria is an emerging cause of abdominal infections. Case presentation We herein describe two cases of intra-abdominal abscesses due to monomicrobial infection by Klebsiella pneumoniae Sequence Type 258 producing K. pneumoniae carbapenemase 3 (KPC-Kp. In case 1, a 50-year-old HIV-negative Italian woman with chronic pancreatitis showed infection of a pancreatic pseudocystic lesion caused by KPC-Kp. In case 2, a 64-year-old HIV- negative Italian woman with pancreatic neoplasm and liver metastases developed a liver abscess due to KPC after surgery. Both women were admitted to our hospital but to different surgical units. The clonal relationship between the two isolates was investigated by pulsed-field gel electrophoresis (PFGE. In case 2, the patient was already colonized at admission and inter-hospital transmission of the pathogen was presumed. A long-term combination regimen of colistin with tigecycline and percutaneous drainage resulted in full recovery and clearance of the multidrug-resistant (MDR pathogen. Conclusions Timely microbiological diagnosis, the combined use of new and old antibiotics and radiological intervention appeared to be valuable in managing these serious conditions. The emergence and dissemination of MDR organisms is posing an increasing challenge for physicians to develop new therapeutic strategies and control and prevention frameworks.

If elimination of microbes and healing is not achieved, or if the immune system is dysregulated, chronic inflammation ensues. Immune cells become engaged in prolonged...... reactions with other cell types in vessels and organs, frequently with superimposed autoreactive T-cells and autoantibody-producing B-cells/plasma cells.

    Full Text Available Post-ischemic inflammation is important in ischemic stroke pathology. However, details of the inflammation process, its resolution after stroke and its effect on pathology and neural damage have not been clarified. Brain swelling, which is often fatal in ischemic stroke patients, occurs at an early stage of stroke due to endothelial cell injury and severe inflammation by infiltrated mononuclear cells including macrophages, neutrophils, and lymphocytes. At early stage of inflammation, macrophages are activated by molecules released from necrotic cells (danger-associated molecular patterns (DAMPs, and inflammatory cytokines and mediators that increase ischemic brain damage by disruption of the blood-brain barrier are released. After post-ischemic inflammation, macrophages function as scavengers of necrotic cell and brain tissue debris. Such macrophages are also involved in tissue repair and neural cell regeneration by producing tropic factors. The mechanisms of inflammation resolution and conversion of inflammation to neuroprotection are largely unknown. In this review, we summarize information accumulated recently about DAMP-induced inflammation and the neuroprotective effects of inflammatory cells, and discuss next generation strategies to treat ischemic stroke.

    S Nilima

    2011-01-01

    Full Text Available Background: One of the major direct or indirect targets of ultraviolet exposure of skin is the melanocyte or the melanin -forming cell. Epidermal melanocytes act as a trap for free radicals. Based on the protective role of melanocytes in medical literature, the role of melanin pigmentation in gingiva needs to be elucidated. Periodontal pathogens and their products demonstrate the ability to induce the generation of reactive oxygen species. Hence purpose of this study was to unravel the protective role of melanin (if any against the gingival inflammation. Materials and Methods: A total of 80 subjects; 20 in each group were selected. The selection of subjects regarding gingival pigmentation was based on Dummett′s scoring criteria 0, 3. A complete medical, dental history and an informed consent were obtained from the patients. After evaluation of clinical parameters the GCF was collected using microcapillary pipettes at the selected sites. IL-1β levels were quantitated using ELISA. Results: In non-pigmented healthy and gingivitis groups, there was a positive correlation between plaque index, gingival index and bleeding index versus IL-1β level: indicating an increase in the biochemical mediator of inflammation corresponding to an increase in the clinical parameters of inflammation. Also a positive correlation was found between the gingival index and bleeding index versus the IL-1β levels in the pigmented healthy group. The pigmented gingivitis groups showed a negative correlation between the plaque index, gingival index and bleeding index. Conclusions: The clinical markers of inflammation such as gingival index, bleeding index was of low numerical value in pigmented group than in the non-pigmented group, supposedly due to the protective action of melanin. The negative correlation of clinical markers of inflammation to the IL-1β levels in the pigmented gingivitis group could possibly be attributed to the protective role of melanins.

    Pain and functional limitation are frequent in symptomatic tendinopathy. The essential lesion of tendinopathy is a failed healing response. Understanding the cellular and molecular mechanisms involved in a failed healing response during the early stages of pathogenesis of tendinopathy would help to develop new and effective treatments. The role of inflammation in the development of tendon pathologies has been revived during the last few years, in particular during the first phases of tendinopathies, when "early tendinopathy" may not be clinically evident. This review outlines the possible molecular events that occur in the first phases of tendinopathy onset, stressing the role of pro-inflammatory cytokines, proteolytic enzymes, growth factors and healing genes in the development of tendon disorders.

  16. PET imaging of inflammation

    2014-01-01

    Inflammatory diseases are common place and often chronic. Most inflammatory cells have increased uptake of glucose which is enhanced in the presence of local cytokines. Therefore, imaging glucose metabolism by the means of 18F-fluoro-deoxy-glucose (FDG) positron emission tomography (PET) holds significant promise in imaging focal inflammation. Most of the work published involved small series of patients with either vasculitis, sarcoid or rheumatoid arthritis. It would appear that FDG PET is a simple and effective technique to identify inflammatory tissue in these conditions. There is even some work to suggest that by comparing baseline and early post therapy scans clinical outcome can be predicted. This would appear to be true with vasculitis as well as retroperitoneal fibrosis. The number of patients in each study is small but the evidence is compelling enough to recommend FDG PET imaging in the routine care of these patients.

    Diabetes causes a number of metabolic and physiologic abnormalities in the retina, but which of these abnormalities contribute to recognized features of diabetic retinopathy (DR) is less clear. Many of the molecular and physiologic abnormalities that have been found to develop in the retina in diabetes are consistent with inflammation. Moreover, a number of anti-inflammatory therapies have been found to significantly inhibit development of different aspects of DR in animal models. Herein, we review the inflammatory mediators and their relationship to early and late DR, and discuss the potential of anti-inflammatory approaches to inhibit development of different stages of the retinopathy. We focus primarily on information derived from in vivo studies, supplementing with information from in vitro studies were important. PMID:21635964

    2014-01-01

    Interactions between metabolism and immunity play a pivotal role in the development of obesity-associated chronic co-morbidities. Obesity involves impairment of immune function affecting both the innate and adaptive immune system. This leads to increased risk of infections as well as chronic low-grade inflammation, which in turn causes metabolic dysfunction (e.g. insulin resistance) and chronic disease (e.g. type-2 diabetes). Gut microbiota has emerged as one of the key factors regulating early events triggering inflammation associated with obesity and metabolic dysfunction. This effect seems to be related to diet- and obesity-associated changes in gut microbiota composition and to increased translocation of immunogenic bacterial products, which activate innate and adaptive immunity in the gut and beyond, contributing to an increase in inflammatory tone. Innate immune receptors, like Toll-like receptors (TLRs), are known to be up-regulated in the tissue affected by most inflammatory disorders and activated by both specific microbial components and dietary lipids. This triggers several signaling transduction pathways (e.g. JNK and IKKβ/NF-κB), leading to inflammatory cytokine and chemokine (TNF-α, IL-1, MCP1) production and to inflammatory cell recruitment, causing insulin resistance. T-cell differentiation into effector inflammatory or regulatory T cells also depends on the type of TLR activated and on cytokine production, which in turn depends upon gut microbiota-diet interactions. Here, we update and discuss our current understanding of how gut microbiota could contribute to defining whole-body metabolism by influencing diverse components of the innate and adaptive immune system, both locally and systemically.

To identify the factors causing acute inflammation in the solitary molars without second molars or without second and first molars, ages of patients and rates of acute inflammation in 75 horizontal incompletely impacted mandibular molars in contact or not in contact with molars in subjects 41 years old or older were studied using orthopantomographs. Acute inflammation was seen in nine third molars out of 48 third molars in contact with second molars (18.8%, whereas acute inflammation was seen in 11 molars out of 19 solitary molars without second molars or without first and second molars (57.9% (p < 0.01. The mean age of 48 subjects with third molars in contact with the second molar was 50.42 ± 7.62 years, and the mean age of 19 subjects with isolated molars was 65.16 ± 10.41 years (p < 0.0001. These indicate that a solitary horizontal incompletely impacted molar leads more frequently to acute inflammation along with aging due to possible bone resorption resulting from teeth loss.Keywords: mandible, third molar, impaction, elderly, acute inflammation, solitary molar

    2017-11-01

    In amyloid β-related angiitis of the central nervous system (also called cerebral amyloid angiopathy-related inflammation), cerebral amyloid angiopathy occurs in association with primary vasculitis of small- and medium-sized leptomeningeal and cortical arteries. To avoid brain biopsy, clinicoradiological criteria (including clinical features due to inflammation-related uni/multifocal white matter hyperintensities) for the diagnosis of cerebral amyloid angiopathy-related inflammation have been validated recently. We report 3 cases with acute symptoms directly related to cerebral amyloid angiopathy in the presence of asymptomatic cerebral amyloid angiopathy-related inflammation hyperintensities on initial magnetic resonance imaging. Recognizing radiological features of cerebral amyloid angiopathy-related inflammation in patients with cerebral amyloid angiopathy is important because radiological isolated cerebral amyloid angiopathy-related inflammation may become symptomatic and immunosuppressive treatment is often effective in cerebral amyloid angiopathy-related inflammation, although optimal treatment regimen is yet unknown. In contrast, apart from hypertension treatment, few therapeutic options exist in cerebral amyloid angiopathy. Copyright © 2017 National Stroke Association. Published by Elsevier Inc.

    2015-01-01

    Inflammation entails a complex set of defense mechanisms acting in concert to restore the homeostatic balance in organisms after damage or pathogen invasion. This immune response consists of the activity of various immune cells in a highly complex manner. Inflammation is a double-edged sword as it is reported to have both detrimental and beneficial consequences. In this review, we discuss the effects of inflammation on stem cell activity, focusing primarily on neural stem/progenitor cells in mammals and zebrafish. We also give a brief overview of the effects of inflammation on other stem cell compartments, exemplifying the positive and negative role of inflammation on stemness. The majority of the chronic diseases involve an unremitting phase of inflammation due to improper resolution of the initial pro-inflammatory response that impinges on the stem cell behavior. Thus, understanding the mechanisms of crosstalk between the inflammatory milieu and tissue-resident stem cells is an important basis for clinical efforts. Not only is it important to understand the effect of inflammation on stem cell activity for further defining the etiology of the diseases, but also better mechanistic understanding is essential to design regenerative therapies that aim at micromanipulating the inflammatory milieu to offset the negative effects and maximize the beneficial outcomes.

    Full Text Available Bone metabolism is tightly regulated by the immune system. Accelerated bone destruction is observed in many bone diseases, such as rheumatoid arthritis, fracture, and particle-induced osteolysis. These pathological conditions are associated with inflammatory responses, suggesting the contribution of inflammation to bone destruction. Macrophages are heterogeneous immune cells and are polarized into the proinflammatory M1 and antiinflammatory M2 phenotypes in different microenvironments. The cytokines produced by macrophages depend on the macrophage activation and polarization. Macrophages and macrophage-derived cytokines are important to bone loss in inflammatory bone disease. Recent studies have shown that macrophages can be detected in bone tissue and interact with bone cells. The interplay between macrophages and bone cells is critical to bone formation and repair. In this article, we focus on the role of macrophages in inflammatory bone diseases, as well as discuss the latest studies about macrophages and bone formation, which will provide new insights into the therapeutic strategy for bone disease.

    Full Text Available In our country preservation of the population reproductive health is a high-priority direction of modern medicine. In many cases, the cause of reproductive disorders in women is a chronic infectious inflammation of the small pelvis, the frequency of which in recent years had no tendency to decrease. The choice of inactivated vaccine of Staphylococcus aureus as a phlogogen was due to the fact that the etiological role of the aerobic infection remains the leading one in gynecological pathology. The aim of research was studying of the ability to use the inactivated vaccine of Staphylococcus aureus strain 209 for modeling of chronic inflammation of the ovaries in laboratory mice. Materials and methods. 25 mature outbred white female mice weighing 18-20 g were used as experimental animals, which formed next groups: 1 control (n=5 – animals without any interventions and 2 experimental (n=20 – animals with one-fold intraperitoneal injection of inactivated Staphylococcus aureus strain 209 vaccine in the dose of 50х106 microbial bodies in 0,3 ml of physiological solution. Efficiency of the modeling pathology was performed by histomorphometric and hematological methods on the 7th, 14th, 21st and 31st days. All the manipulations with animals were carried out in accordance to the requirements of bioethics and the international principles of the European Convention for the protection of vertebrate animals. For statistical study ANOVA and t-Student tests were used with application of Microsoft Excel Program. Results. In the group of control animals the form and histological structure of ovaries were regular for mature mice without signs of inflammatory changes. The leukocyte infiltration, hemodynamic disorders and minor dystrophic changes of granulosa cells were determined on the 7th day in the ovaries of experimental animals. The increasing of observation period up to 14 days on the background of hemodynamic disorders resulted in the appearance of

    It has been well-recognized that inflammation alongside tissue repair and damage maintaining tissue homeostasis determines the initiation and progression of complex diseases. Albeit with the accomplishment of having captured the most critical inflammation-involved molecules, genetic susceptibilities, epigenetic factors, and environmental factors, our schemata on the role of inflammation in complex diseases remain largely patchy, in part due to the success of reductionism in terms of research methodology per se. Omics data alongside the advances in data integration technologies have enabled reconstruction of molecular and genetic inflammation networks which shed light on the underlying pathophysiology of complex diseases or clinical conditions. Given the proven beneficial role of anti-inflammation in coronary heart disease as well as other complex diseases and immunotherapy as a revolutionary transition in oncology, it becomes timely to review our current understanding of the molecular and genetic inflammation networks underlying major human diseases. In this review, we first briefly discuss the complexity of infectious diseases and then highlight recently uncovered molecular and genetic inflammation networks in other major human diseases including obesity, type II diabetes, coronary heart disease, late onset Alzheimer's disease, Parkinson's disease, and sporadic cancer. The commonality and specificity of these molecular networks are addressed in the context of genetics based on genome-wide association study (GWAS). The double-sword role of inflammation, such as how the aberrant type 1 and/or type 2 immunity leads to chronic and severe clinical conditions, remains open in terms of the inflammasome and the core inflammatome network features. Increasingly available large Omics and clinical data in tandem with systems biology approaches have offered an exciting yet challenging opportunity toward reconstruction of more comprehensive and dynamic molecular and genetic

    Inflammation, particularly low-grade chronic inflammation, appears to affect several brain functions, from early brain development to the development of neurodegenerative disorders and perhaps some psychiatric diseases. On the other hand, nutrition and dietary components and patterns have a plethora of anti- and pro-inflammatory effects that could be linked to cognitive function. Even a modest effect of nutrition on cognitive decline could have significant implications for public health. This paper summarizes the available evidence regarding inflammation as a key mechanism in cognitive function and nutritional pro- or anti-inflammatory effects with the purpose of linking the apparent disparate disciplines of nutrition, immunity, and neurology.

    Epilepsy is associated with a high incidence of comorbid neurologic and psychiatric disorders. This review focuses on the association of epilepsy with autism spectrum disorder (ASD) and depression. There is high concordance of these behavioral pathologies with epilepsy. We review data that unambiguously reveal that epilepsy, ASD, and depression are associated with elevated brain inflammatory markers and that these may interact with serotoninergic pathways. Interference with inflammatory pathways or actions can reduce the severity of seizures, depression, and ASD-like behavior. Inflammation in the brain can be induced by seizure activity as well as by behavioral, environmental, and physiologic stressors. Furthermore, induction of inflammation at an early time point during gestation and in early neonatal life can precipitate both an ASD-like phenotype as well as a more excitable brain. It appears likely that priming of the brain due to early inflammation could provide a means by which subsequent inflammatory processes associated with epilepsy, ASD, and depression may lead to comorbidity.

    India ink or graphite partides injected into an area of inflammation fail to disseminate to the tributary lymph nodes. When injected into a normal peritoneal cavity they rapidly appear in the retrosternal lymph nodes. When injected into an inflamed peritoneal cavity they are fixed in situ and fail to reach the regional lymph nodes. Graphite particles injected in the circulating blood stream enter an inflamed area both as free particles owing to increased capillary permeability and also as phagocyted material within leucocytes. Bacteria (B. prodigiosus) injected into inflamed tissue are fixed at the site of inflammation and fail to disseminate to the regional lymph nodes as readily as when injected into normal tissue. Bacteria (B. prodigiosus) injected at the periphery of an inflamed area do not readily penetrate into the site of inflammation. The experiments furnish evidence, in addition to that already provided, that fixation of foreign substances by the inflammatory reaction is primarily due to mechanical obstruction caused by a fibrin network and by thrombosed lymphatics at the site of inflammation. Bacteria (B. prodigiosus and B. pyocyaneus) injected intravenously rapidly enter an inflamed area. It is suggested that localization of bacteria in a locus minoris resistentiae may be explained as the result of increased capillary permeability with subsequent accumulation and fixation of bacteria from the blood stream at the point of injury.

    Clinical signs and symptoms, as well as medical and dental history, are all considered in the clinical determination of gingival inflammation and periodontal disease severity. However, the "biologic systems model" highlights that the clinical presentation of periodontal disease is closely tied to the underlying biologic phenotype. We propose that the determination and integration of subject-level factors, microbial composition, systemic immune response, and gingival tissue inflammatory mediator responses will better reflect the biology of the biofilm-gingival interface in a specific patient and may provide insights on clinical management. Disease classifications and multivariable models further refine the biologic basis for the increasing severity of periodontal disease expression. As such, new classifications may better identify disease-susceptible and treatment-non-responsive individuals than current classifications that are heavily influenced by probing and attachment level measurements alone. New data also suggest that the clinical characteristics of some complex diseases, such as periodontal disease, are influenced by the genetic and epigenetic contributions to clinical phenotype. Although the genetic basis for periodontal disease is considered imperative for setting an inflammatory capacity for an individual and, thus, a threshold for severity, there is evidence to suggest an epigenetic component is involved as well. Many factors long associated with periodontitis, including bacterial accumulations, smoking, and diabetes, are known to produce strong epigenetic changes in tissue behavior. We propose that we are now able to rethink periodontal disease in terms of a biologic systems model that may help to establish more homogeneous diagnostic categories and can provide insight into the expected response to treatment.

  11. Apoptosis and inflammation

    1995-01-01

    Full Text Available During the last few decades it has been recognized that cell death is not the consequence of accidental injury, but is the expression of a cell suicide programme. Kerr et al. (1972 introduced the term apoptosis. This form of cell death is under the influence of hormones, growth factors and cytokines, which depending upon the receptors present on the target cells, may activate a genetically controlled cell elimination process. During apoptosis the cell membrane remains intact and the cell breaks into apoptotic bodies, which are phagocytosed. Apoptosis, in contrast to necrosis, is not harmful to the host and does not induce any inflammatory reaction. The principal event that leads to inflammatory disease is cell damage, induced by chemical/physical injury, anoxia or starvation. Cell damage means leakage of cell contents into the adjacent tissues, resulting in the capillary transmigration of granulocytes to the injured tissue. The accumulation of neutrophils and release of enzymes and oxygen radicals enhances the inflammatory reaction. Until now there has been little research into the factors controlling the accumulation and the tissue load of granulocytes and their histotoxic products in inflammatory processes. Neutrophil apoptosis may represent an important event in the control of intlamtnation. It has been assumed that granulocytes disintegrate to apoptotic bodies before their fragments are removed by local macrophages. Removal of neutrophils from the inflammatory site without release of granule contents is of paramount importance for cessation of inflammation. In conclusion, apoptotic cell death plays an important role in inflammatory processes and in the resolution of inflammatory reactions. The facts known at present should stimulate further research into the role of neutrophil, eosinophil and macrophage apoptosis in inflammatory diseases.

    2016-06-01

    Aging is characterized by a progressive loss of tissue function and an increased susceptibility to injury and disease. Many age-associated pathologies manifest an inflammatory component, and this has led to the speculation that aging is at least in part caused by some form of inflammation. However, whether or not inflammation is truly a cause of aging, or is a consequence of the aging process is unknown. Recent work using Drosophila has uncovered a mechanism where the progressive loss of lamin-B in the fat body upon aging triggers systemic inflammation. This inflammatory response perturbs the local immune response of the neighboring gut tissue and leads to hyperplasia. Here, we will discuss the literature connecting lamins to aging and inflammation.

    2012-04-01

    Over the last decade, the Tec family of nonreceptor tyrosine kinases (Btk, Tec, Bmx, Itk, and Rlk) have been shown to play a key role in inflammation and bone destruction. Bruton's tyrosine kinase (Btk) has been the most widely studied due to the critical role of this kinase in B-cell development and recent evidence showing that blocking Btk signaling is effective in ameliorating lymphoma progression and experimental arthritis. This review will examine the role of TFK in myeloid cell function and the potential of targeting these kinases as a therapeutic intervention in autoimmune disorders such as rheumatoid arthritis.

    2017-08-01

    The review deals with inflammation in heart failure (HF). Many data show that systemic inflammation is frequent in HF and implicate that inflammation contributes to damage and dysfunction of the cardiovascular system. Areas Covered: Experimental data have been mainly obtained in acute laboratory animal models. It is questionable whether animals' data can be translated into clinical settings with patients with chronic HF who have concomitant pathologies. The idea of a common inflammatory pathway that characterizes all different forms of clinical HF is unrealistic. It seems realistic that inflammation differs in non-cardiac and cardiac diseases. Research therapeutic options address the use of inhibitors of cytokines, of agents antagonizing oxidative stress, of MMP and of PI3K signaling pathways. Expert Opinion: Considering the many unknowns in our knowledge it is not surprising that early trials aimed to antagonize inflammation in HF have been disappointing. We are far away from having solid therapeutic schedules to use immunomodulation in all subtypes of HF. However, modern trials on HF due to virus infections have proven that immunomodulation is therapeutically effective. We should wisely use the known facts and accept that we have many unknowns. By appropriate selection of the subtypes of HF we may be able to find the appropriate therapy against inflammation in HF.

    Full Text Available Inflammation is a normal acute response of the immune system to pathogens and tissue injury. However, chronic inflammation is known to play a significant role in the pathophysiology of numerous chronic diseases, such as cardiovascular disease, type 2 diabetes mellitus, and cancer. Thus, the impact of dietary factors on inflammation may provide key insight into mitigating chronic disease risk. Eggs are recognized as a functional food that contain a variety of bioactive compounds that can influence pro- and anti-inflammatory pathways. Interestingly, the effects of egg consumption on inflammation varies across different populations, including those that are classified as healthy, overweight, metabolic syndrome, and type 2 diabetic. The following review will discuss the pro- and anti-inflammatory properties of egg components, with a focus on egg phospholipids, cholesterol, the carotenoids lutein and zeaxanthin, and bioactive proteins. The effects of egg consumption of inflammation across human populations will additionally be presented. Together, these findings have implications for population-specific dietary recommendations and chronic disease risk.

  1. Endogenous Receptor Agonists: Resolving Inflammation

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available Controlled resolution or the physiologic resolution of a well-orchestrated inflammatory response at the tissue level is essential to return to homeostasis. A comprehensive understanding of the cellular and molecular events that control the termination of acute inflammation is needed in molecular terms given the widely held view that aberrant inflammation underlies many common diseases. This review focuses on recent advances in the understanding of the role of arachidonic acid and ω-3 polyunsaturated fatty acids (PUFA–derived lipid mediators in regulating the resolution of inflammation. Using a functional lipidomic approach employing LC-MS-MS–based informatics, recent studies, reviewed herein, uncovered new families of local-acting chemical mediators actively biosynthesized during the resolution phase from the essential fatty acids eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA. These new families of local chemical mediators are generated endogenously in exudates collected during the resolution phase, and were coined resolvins and protectins because specific members of these novel chemical families control both the duration and magnitude of inflammation in animal models of complex diseases. Recent advances on the biosynthesis, receptors, and actions of these novel anti-inflammatory and proresolving lipid mediators are reviewed with the aim to bring to attention the important role of specific lipid mediators as endogenous agonists in inflammation resolution.

  6. Purinergic Receptors in Ocular Inflammation

    Directory of Open Access Journals (Sweden)

    Ana Guzman-Aranguez

    2014-01-01

    Full Text Available Inflammation is a complex process that implies the interaction between cells and molecular mediators, which, when not properly “tuned,” can lead to disease. When inflammation affects the eye, it can produce severe disorders affecting the superficial and internal parts of the visual organ. The nucleoside adenosine and nucleotides including adenine mononucleotides like ADP and ATP and dinucleotides such as P1,P4-diadenosine tetraphosphate (Ap4A, and P1,P5-diadenosine pentaphosphate (Ap5A are present in different ocular locations and therefore they may contribute/modulate inflammatory processes. Adenosine receptors, in particular A2A adenosine receptors, present anti-inflammatory action in acute and chronic retinal inflammation. Regarding the A3 receptor, selective agonists like N6-(3-iodobenzyl-5′-N-methylcarboxamidoadenosine (CF101 have been used for the treatment of inflammatory ophthalmic diseases such as dry eye and uveoretinitis. Sideways, diverse stimuli (sensory stimulation, large intraocular pressure increases can produce a release of ATP from ocular sensory innervation or after injury to ocular tissues. Then, ATP will activate purinergic P2 receptors present in sensory nerve endings, the iris, the ciliary body, or other tissues surrounding the anterior chamber of the eye to produce uveitis/endophthalmitis. In summary, adenosine and nucleotides can activate receptors in ocular structures susceptible to suffer from inflammatory processes. This involvement suggests the possible use of purinergic agonists and antagonists as therapeutic targets for ocular inflammation.

    Inflammations represent mediator-induced reactions of the hematopoetic-immunologic cell system resulting from exogenous or endogenous stimuli. On cellular level, an increased expression of inflammatory genes is followed by the release of several mediators. As inflammatory response vascular permeability increases and interstitial oedema develops. Additionally, white blood cells emigrate and several transduction cascades are activated. Radiopharmaceuticals for inflammation scintigraphy should specifically reflect one or several aspects of inflammation pathophysiology on molecular level. A group of elder tracers for this purpose comprised substances that are accumulated due to the permeability of physiological barriers. However, their property to accumulate in all processes with increased vascular permeability results in a comparably low specificity of these methods. In-vitro-labelled granulocytes were the method of choice for scintigraphic imaging of inflammation for years. Investigations with {sup 111}In-labelled granulocytes are still frequently considered as the gold standard to detect inflammation by scintigraphy. The use of antibodies or antibody fragments directed against leucocytes allowed in vivo labelling and substituted more complex techniques of in vitro labelling despite of several disadvantages. Due to the superior imaging quality of positron emission tomography, [{sup 18}F]FDG-labelled leucocytes might result in a renaissance of in vitro methods. In cases of cerebral inflammation, activated microglia was visualised by its increased expression of benzodiazepin receptors. An interesting approach to differentiate between infection and sterile inflammation could be the use of bacterial gyrase inhibitors labelled with radioactive compounds. At present, specificity of this method is still controversially discussed. In search of substances to visualise inflammatory transduction cascades selectively, several chemotactic and chemokinetic cytokines, metabolites

    By means of a questionnaire and medical documentation, the authors studied a group of 569 women of fertile age in whom an IUD had been inserted for a period of 2 years between 1967-72. Among these patients, the authors observed a total of 30 cases of pelvic inflammation at the time of insertion. The authors demonstrated, statistically, that wearers of IUDs who suffer from hypermenorrhea and menorrhagia were more prone to develop pelvic inflammation, especially in cases where the interval of menstrual bleeding was markedly prolonged. These women would therefore be in greater danger by the possible results of these inflammations; i.e., sterility due to fallopian tube occlusion. The authors do not recommend the IUD for young women since it might lead to the intensification and protraction of menstrual bleeding. (author's)

    Sclerosing mesenteritis is a rare benign process that involves inflammation, fat necrosis, and fibrosis of the mesentery. The disease poses great diagnostic challenge due to its nonspecific clinical and diagnostic findings. We report the case of a 75-year-old man who presented with vague abdominal discomfort associated with an intra-abdominal mass. With suspicion of a bowel carcinoid tumor on computed tomography scans, the patient underwent diagnostic laparoscopy. A diagnosis of sclerosing mesenteritis was made on histological examination. The patient's symptoms responded to a combination of immunosuppressive drugs, with no interval change in the size of the mass on radiological examination after fifteen months. PMID:20671922

    Full Text Available BACKGROUND: Obesity-induced inflammation contributes to the development of type 2 diabetes, metabolic syndrome, and cardiovascular disease. CONTENT:The last decade has seen a sharp increase in our appreciation for the macrophage as a critical regulator of metabolic status in obesity. Activation of adipose tissue (AT macrophages within fat depots is coupled with the development of obesity-induced proinflammatory state and insulin resistance (IR. The activation of classically activated M1 macrophages at the expense of anti-inflammatory M2 macrophages has been causally linked to the development of AT inflammation and metabolic syndrome, a pathophysiological state aptly termed as ‘metainflammation’. It is recognized that several proinflammatory cytokines, including interleukin (IL-1β, are implicated in disrupting insulin signaling. Our developing appreciation of links among obesity, inflammation and cardiovascular disease will require multiple complementary approaches to leverage new concepts into translatable outcomes. Careful characterization of human patients, particularly analysis of AT distribution, will be needed to stratify subjects that are most likely obese/metabolically healthy from those that are obese/metabolically unhealthy. SUMMARY: It has been suggested that individuals with the condition known as metabolically healthy obese (MHO may not have the same increased risk for the development of metabolic abnormalities as their non-metabolically healthy counterparts. A complications-centric model for the medical management of obesity emphasizes the identification and staging of complications, and treatment paradigm directed at patients who would gain the most benefit from weight loss.

    Candidemia is an important cause of mortality in healthcare settings. Peripheral lines are a source of candidemia, yet few studies have reported on the clinico-epidemiological features of candidemia due to peripheral-line associated blood stream infection (PLABSI). We conducted a single-centre retrospective cohort study of all patients with candidemia between 2002 and 2013. PLABSI was defined as the presence of at least one of the following: the presence of phlebitis or the resolution of clinical symptoms after peripheral-line withdrawal, with careful exclusion of an alternative explanation for bacteraemia. We described the epidemiology of candidemia and assessed predictive factors of PLABSI due to Candida spp., peripheral line-associated candidemia (PLAC), compared with non-PLAC. A total of 301 episodes of candidemia, including 37 of PLAC, were diagnosed during the study period. Central-line associated blood stream infection, intra-abdominal infection, and infection of unknown source accounted for the remaining 233, 14, and 17 cases, respectively. The overall incidence rate of candidemia was 0.11/1000 patient-days. In multivariate analysis, cephalosporin exposure (odds ratio [OR] = 2.22, 95% CI 1.04-4.77), polymicrobial bacteraemia/fungaemia (OR = 2.87, 95% CI 1.02-8.10), and ID specialist consultation (OR = 2.40, 95% CI 1.13-5.13) were identified as independent predictors of PLAC. Although non-PLAC had a higher mortality, the length of hospital stay after candidemia was similar between the two groups and candidemia duration was longer in the PLAC group. PLACs are an important cause of candidemia in hospitalized patients. Appropriate identification and management of PLAC are crucial.

    Pastelín Hernández, Gustavo; Rosas Peralta, Martín

    2007-01-01

    Inflammatory status is involved in the pathophysiology of several cardiovascular disorders and in the genesis of high blood pressure. In this disease inflammation results from the activity of several hematological cells as well as the presence of chemotactic factors, immunological reactivity and hyperactivity of vasoconstrictor systems as that of the renin-angiotensin. Clinical evaluation of hypertension recommends secreening of several proinflammatory substances in hypertensive patients in order to evaluate their level of cardiovascular risk. Interleukin-6 and C reactive protein have been considered the most usual risk biomarkers. Interleukin 6 is a potent proinflammatory compound which participates in the acute fase of the tissular reaction to lesions associated to immunological, ischemic or oxidative stress. C reactive protein participates during inflammation activating the first component of complement with disorganization of the phospholipidic array of the endothelial sarcolemmal membrane and the consequent endothelial dysfunction related to the genesis of high blood pressure.

    Assessment of a simple layer peritoneal tube used as an autogenous inferior vena cava replacement. Extensive en-bloc multivisceral resection including major vessels is effective in selected abdominal malignancies, but the need for vascular reconstruction represents a surgical challenge. We describe the use of autologous peritoneum for caval replacement. Autogenous parietal peritoneum without fascial backing was harvested and tubularized to replace the inferior vena cava (IVC) in four patients with complex abdominal tumors. Surgical morbidity was evaluated using the Clavien-Dindo classification, and graft patency was systematically evaluated with ultrasound. All four patients had multiorgan resections for malignancies involving the retro-hepatic IVC, and they all required the replacement of infrarenal and suprarenal IVC segments. Additionally, all four required a right nephrectomy, two had a combined major hepatectomy, and one patient needed a veno-venous bypass. All had an R0 resection. A clinical follow-up took place between 5 and 11 months after surgery for each patient. Four-month graft patency was confirmed by ultra-sound and TDM with no sign of disease recurrence. Autologous peritoneum without fascial backing is a good and safe option for circumferential replacement of IVC after extensive en-bloc tumor resection with IVC involvement.

While the rats were under anesthesia, a hyperinsulinemic ( approximately 900 pM), euglycemic clamp was carried out and local glucose uptake was measured by both the 2-deoxy-D-[(3)H......]glucose and microdialysis techniques. Blood flow was measured by microspheres. Upon insulin stimulation, blood flow generally decreased in AT. Flow was higher in mesenteric tissue than in other ATs, whereas insulin-mediated glucose uptake did not differ between ATs. Training doubled the glucose infusion rate during...

    Cancer survivorship focuses largely on improving quality of life. We aimed to determine the rate of ventral incisional hernia (VIH) formation after cancer resection, with implications for survivorship. Patients without prior VIH who underwent abdominal malignancy resections at a tertiary center were followed up to 2 years. Patients with a viewable preoperative computed tomography (CT) scan and CT within 2 years postoperatively were included. Primary outcome was postoperative VIH on CT, reviewed by a panel of surgeons uninvolved with the original operation. Factors associated with VIH were determined using Cox proportional hazards regression. 1847 CTs were reviewed among 491 patients (59 % men), with inter-rater reliability 0.85 for the panel. Mean age was 60 ± 12 years; mean follow-up time 13 ± 8 months. VIH occurred in 41 % and differed across diagnoses: urologic/gynecologic (30 %), colorectal (53 %), and all others (56 %) (p VIH (adjusting for stage, age, adjuvant therapy, smoking, and steroid use) included: incision location [flank (ref), midline, hazard ratio (HR) 6.89 (95 %CI 2.43-19.57); periumbilical, HR 6.24 (95 %CI 1.84-21.22); subcostal, HR 4.55 (95 %CI 1.51-13.70)], cancer type [urologic/gynecologic (ref), other {gastrointestinal, pancreatic, hepatobiliary, retroperitoneal, and others} HR 1.86 (95 %CI 1.26-2.73)], laparoscopic-assisted operation [laparoscopic (ref), HR 2.68 (95 %CI 1.44-4.98)], surgical site infection [HR 1.60 (95 %CI 1.08-2.37)], and body mass index [HR 1.06 (95 %CI 1.03-1.08)]. The rate of VIH after abdominal cancer operations is high. VIH may impact cancer survivorship with pain and need for additional operations. Further studies assessing the impact on QOL and prevention efforts are needed.

    With current literature quoting mortality rates up to 45%, emergency high-risk abdominal surgery has, compared with elective surgery, a significantly greater risk of death and major complications. The Surgical Apgar Score (SAS) is predictive of outcome in elective surgery, but has never been validated exclusively in an emergency setting. A consecutive prospective single-center cohort study of 355 adults undergoing emergency high-risk abdominal surgery between June 2013 and May 2014 is presented. The primary outcome measure was 30-day mortality. Secondary outcome measures were postoperative major complications, defined according to the Clavien-Dindo scale as well as the American College of Surgeons' National Surgical Quality Improvement Program guidelines, and intensive care unit admission. The SAS was calculated postoperatively. Cochran-Armitage test for trend was used to evaluate the incidence of both outcomes. Area under the curve was used to demonstrate the scores' discriminatory power. One hundred eighty-one (51.0%) patients developed minor or no complications. The overall incidence of major complications was 32.7% and the overall death rate was 16.3%. Risk of major complications, death, and intensive care unit admission increased significantly with decreasing SAS (P high-risk abdominal surgery. Despite its predictive value, the SAS cannot in its current version be recommended as a standalone prognostic tool in an emergency setting.

    Full Text Available The finding of intraperitoneal foreign body complicating surgical intervention broadly remains as an issue of safety in the operative room, a source of emotive concern for the patient, and an upsetting but equally embarrassing situation to the surgeon and the team. However, in the media world, it is a source of sumptuous and captivating headline on the newspaper and to the legal profession, an attractive case to prosecute. A middle age teacher presented with secondary infertility. She had emergency laparotomy fifteen years ago for ruptured tubal ectopic pregnancy in a private hospital and postoperative period was uneventful. Amongst other investigations to find out the cause of infertility, she had hysterosalpingography and a radio-opaque clamp was visualized on the films. She was counselled and had laparotomy. A pair of surgical Kocher clamps was retrieved buried in the mesentery.

    2017-01-01

    Monocytes are circulating leukocytes important in both innate and adaptive immunity, primarily functioning in immune defense, inflammation, and tissue remodeling. There are 2 subsets of monocytes in mice (3 subsets in humans) that are mobilized from the bone marrow and recruited to sites of inflammation, where they carry out their respective functions in promoting inflammation or facilitating tissue repair. Our understanding of the fate of these monocyte subsets at the site of inflammation is constantly evolving. This brief review highlights the plasticity of monocyte subsets and their conversion during inflammation and injury. © 2016 American Heart Association, Inc.

Finally, we considered how a single cell model of bistable phenotype...... expression leads to bimodal expression on a population level and how the distribution of phenotype expression is altered by gene copy number variations. We assumed that a positive feedback is responsible for the bistability at the single cell level and show that the position of the feedback relative to gene...

  12. Key Role of DAMP in Inflammation, Cancer, and Tissue Repair.

    Science.gov (United States)

    Pandolfi, Franco; Altamura, Simona; Frosali, Simona; Conti, Pio

    2016-05-01

    This review aimed to take stock of the current status of research on damage-associated molecular pattern (DAMP) protein. We discuss the Janus-faced role of DAMP molecules in inflammation, cancer, and tissue repair. The high-mobility group box (HMGB)-1 and adenosine triphosphate proteins are well-known DAMP molecules and have been primarily associated with inflammation. However, as we shall see, recent data have linked these molecules to tissue repair. HMGB1 is associated with cancer-related inflammation. It activates nuclear factor kB, which is involved in cancer regulation via its receptor for advanced glycation end-products (RAGE), Toll-like receptors 2 and 4. Proinflammatory activity and tissue repair may lead to pharmacologic intervention, by blocking DAMP RAGE and Toll like receptor 2 and 4 role in inflammation and by increasing their concentration in tissue repair, respectively. We conducted a MEDLINE search for articles pertaining to the various issues related to DAMP, and we discuss the most relevant articles especially (ie, not only those published in journals with a higher impact factor). A cluster of remarkable articles on DAMP have appeared in the literature in recent years. Regarding inflammation, several strategies have been proposed to target HMGB1, from antibodies to recombinant box A, which interacts with RAGE, competing with the full molecule. In tissue repair, it was reported that the overexpression of HMGB1 or the administration of exogenous HMGB1 significantly increased the number of vessels and promoted recovery in skin-wound, ischemic injury. Due to the bivalent nature of DAMP, it is often difficult to explain the relative role of DAMP in inflammation versus its role in tissue repair. However, this point is crucial as DAMP-related treatments move into clinical practice. Copyright © 2016 Elsevier HS Journals, Inc. All rights reserved.

    Dengue virus (DENV) is a mosquito-borne flavivirus that causes significant global human disease and mortality. One approach to develop treatments for DENV infection and the prevention of severe disease is through investigation of natural medicines. Inflammation plays both beneficial and harmful roles during DENV infection. Studies have proposed that the oxidative stress response may be one mechanism responsible for triggering inflammation during DENV infection. Thus, blocking the oxidative stress response could reduce inflammation and the development of severe disease. Garlic has been shown to both reduce inflammation and affect the oxidative stress response. Here, we show that the garlic active compounds diallyl disulfide (DADS), diallyl sulfide (DAS) and alliin reduced inflammation during DENV infection and show that this reduction is due to the effects on the oxidative stress response. These results suggest that garlic could be used as an alternative treatment for DENV infection and for the prevention of severe disease development. PMID:28644404

    Full Text Available Obesity is a public health problem that has reached epidemic proportions with an increasing worldwide prevalence. The global emergence of obesity increases the risk of developing chronic metabolic disorders. Thus, it is an economic issue that increased the costs of the comorbidities associated. Moreover, in recent years, it has been demonstrated that obesity is associated with chronic systemic inflammation, this status is conditioned by the innate immune system activation in adipose tissue that promotes an increase in the production and release of pro-inflammatory cytokines that contribute to the triggering of the systemic acute-phase response which is characterized by elevation of acute-phase protein levels. On this regard, low-grade chronic inflammation is a characteristic of various chronic diseases such as metabolic syndrome, cardiovascular disease, diabetes, hypertension, non-alcoholic fatty liver disease, and some cancers, among others, which are also characterized by obesity condition. Thus, a growing body of evidence supports the important role that is played by the inflammatory response in obesity condition and the pathogenesis of chronic diseases related.

    Full Text Available Lactobacillus species colonize the human gastrointestinal tract and are rarely pathogenic. We present a case involving a cirrhotic patient who presented with sepsis and was found to have peritoneal cultures demonstrating Lactobacillus as the sole pathogen concerning for spontaneous bacterial peritonitis. Treatment was achieved with high-dose penicillin and clindamycin but the patient developed hepatorenal syndrome and died from acute renal failure. Intra-abdominal Lactobacillus infections are typically seen in patients undergoing peritoneal dialysis or who have recently had bowel perforation. There are few case reports of spontaneous Lactobacillus peritonitis in patients with cirrhosis. Our case report addresses the challenges of Lactobacillus treatment and suggests antibiotic coverage of commensal organisms in patients who do not improve with standard management.

    Acne vulgaris affects as much as 80% of the adolescent population and persists in approximately 3% of middle-aged adults. Only a percentage of these persons seek medical help, however, acne can cause levels of anxiety and depression akin to a chronic illness. A recurring question from patients who seek help from various healthcare professionals - their pharmacist, family doctor or dermatologist, is "why?" They also ask questions about a possible familial link, the impact of their diet and the association with their hormones. The following review aims to link these factors with the end result - inflammation.

  19. Heme oxygenase-1, oxidation, inflammation and atherosclerosis

    Directory of Open Access Journals (Sweden)

    Jesus A Araujo

    2012-07-01

    Full Text Available Atherosclerosis is an inflammatory process of the vascular wall characterized by the infiltration of lipids and inflammatory cells. Oxidative modifications of infiltrating low density lipoproteins and induction of oxidative stress play a major role in lipid retention in the vascular wall, uptake by macrophages and generation of foam cells, a hallmark of this disorder. The vasculature has a plethora of protective resources against oxidation and inflammation, many of them regulated by the Nrf2 transcription factor. Heme oxygenase-1 (HO-1 is a Nrf2-regulated gene that plays a critical role in the prevention of vascular inflammation. It is the inducible isoform of heme oxygenase, responsible for the oxidative cleavage of heme groups leading to the generation of biliverdin, carbon monoxide and release of ferrous iron. HO-1 has important antioxidant, antiinflammatory, antiapoptotic, antiproliferative and immunomodulatory effects in vascular cells, most of which play a significant role in the protection against atherogenesis. HO-1 may also be an important feature in macrophage differentiation and polarization to certain subtypes. The biological effects of HO-1 are largely attributable to its enzymatic activity, which can be conceived as a system with three arms of action, corresponding to its three enzymatic byproducts. HO-1 mediated vascular protection may be due to a combination of systemic and vascular local effects. It is usually expressed at low levels but can be highly upregulated in the presence of several proatherogenic stimuli. The HO-1 system is amenable for use in the development of new therapies, some of them currently under experimental and clinical trials. Interestingly, in contrast to the HO-1 antiatherogenic actions, the expression of its transcriptional regulator Nrf2 leads to proatherogenic effects instead. This article reviews the evidence that supports the antiatherogenic role of HO-1, potential pathways and mechanisms mediating

  20. Is Pulp Inflammation a Prerequisite for Pulp Healing and Regeneration?

    2015-01-01

    The importance of inflammation has been underestimated in pulpal healing, and in the past, it has been considered only as an undesirable effect. Associated with moderate inflammation, necrosis includes pyroptosis, apoptosis, and nemosis. There are now evidences that inflammation is a prerequisite for pulp healing, with series of events ahead of regeneration. Immunocompetent cells are recruited in the apical part. They slide along the root and migrate toward the crown. Due to the high alkalinity of the capping agent, pulp cells display mild inflammation, proliferate, and increase in number and size and initiate mineralization. Pulp fibroblasts become odontoblast-like cells producing type I collagen, alkaline phosphatase, and SPARC/osteonectin. Molecules of the SIBLING family, matrix metalloproteinases, and vascular and nerve mediators are also implicated in the formation of a reparative dentinal bridge, osteo/orthodentin closing the pulp exposure. Beneath a calciotraumatic line, a thin layer identified as reactionary dentin underlines the periphery of the pulp chamber. Inflammatory and/or noninflammatory processes contribute to produce a reparative dentinal bridge closing the pulp exposure, with minute canaliculi and large tunnel defects. Depending on the form and severity of the inflammatory and noninflammatory processes, and according to the capping agent, pulp reactions are induced specifically. PMID:26538825

  1. Inflammation and cardiac dysfunction during sepsis, muscular dystrophy, and myocarditis

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available Inflammation plays an important role in cardiac dysfunction under different situations. Acute systemic inflammation occurring in patients with severe burns, trauma, and inflammatory diseases causes cardiac dysfunction, which is one of the leading causes of mortality in these patients. Acute sepsis decreases cardiac contractility and impairs myocardial compliance. Chronic inflammation such as that occurring in Duchenne muscular dystropshy and myocarditis may cause adverse cardiac remodeling including myocyte hypertrophy and death, fibrosis, and altered myocyte function. However, the underlying cellular and molecular mechanisms for inflammatory cardiomyopathy are still controversial probably due to multiple factors involved. Potential mechanisms include the change in circulating blood volume; a direct inhibition of myocyte contractility by cytokines (tumor necrosis factor (TNF-a, interleukin (IL-1b; abnormal nitric oxide and reactive oxygen species (ROS signaling; mitochondrial dysfunction; abnormal excitation-contraction coupling; and reduced calcium sensitivity at the myofibrillar level and blunted b-adrenergic signaling. This review will summarize recent advances in diagnostic technology, mechanisms, and potential therapeutic strategies for inflammation-induced cardiac dysfunction.

  2. Obstructive sleep apnea and inflammation.

    McNicholas, Walter T

    2012-02-01

    The pathogenesis of cardiovascular complications in obstructive sleep apnea syndrome (OSAS) is not fully understood but is likely multifactorial in origin. Inflammatory processes play an important role in the pathogenesis of atherosclerosis, and circulating levels of several markers of inflammation have been associated with future cardiovascular risk. These include cell adhesion molecules such as intercellular adhesion molecule-1 and selectins, cytokines such as tumour necrosis factor alpha and interleukin 6, chemokines such as interleukin 8, and C-reactive protein. There is also increasing evidence that inflammatory processes play an important role in the cardiovascular pathophysiology of OSAS and many of the inflammatory markers associated with cardiovascular risk have been reported as elevated in patients with OSAS. Furthermore, animal and cell culture studies have demonstrated preferential activation of inflammatory pathways by intermittent hypoxia, which is an integral feature of OSAS. The precise role of inflammation in the development of cardiovascular disease in OSAS requires further study, particularly the relationship with oxidative stress, metabolic dysfunction, and obesity.

    2017-01-01

    Inflammation may be caused by a variety of factors and is a hallmark of a plethora of acute and chronic diseases. The purpose of inflammation is to eliminate the initial cell injury trigger, to clear out dead cells from damaged tissue and to initiate tissue regeneration. Despite the wealth of knowledge regarding the involvement of cellular communication in inflammation, studies on the role of connexin-based channels in this process have only begun to emerge in the last few years. In this paper, a state-of-the-art overview of the effects of inflammation on connexin signaling is provided. Vice versa, the involvement of connexins and their channels in inflammation will be discussed by relying on studies that use a variety of experimental tools, such as genetically modified animals, small interfering RNA and connexin-based channel blockers. A better understanding of the importance of connexin signaling in inflammation may open up towards clinical perspectives. PMID:27387655

    Coexistence of lung cancer and granulomatous inflammation in the same patient confuses clinicians. We aimed to document the prevalence, clinicopathological features, treatment outcomes and prognosis in patients with coexisting granulomatous inflammation undergoing curative lung resection for lung cancer, in a tuberculosis (TB)-endemic country. An observational cohort study of patients with lung cancer undergoing curative resection between 2012 and 2015 in a tertiary centre in Singapore. One hundred and twenty-seven patients underwent lung resection for cancer, out of which 19 (14.9%) had coexistent granulomatous inflammation in the resected specimen. Median age was 68 years and 58.2% were males. Overall median (range) survival was 451 (22-2452) days. Eighteen (14%) patients died at median duration of 271 days after surgery. The postsurgery median survival for those alive was 494 (29-2452) days in the whole group. Subgroup analysis did not reveal any differences in age, gender, location of cancer, radiological features, type of cancer, chemotherapy, history of TB or survival in patients with or without coexistent granulomatous inflammation. Incidental detection of granulomatous inflammation in patients undergoing lung resection for cancer, even in a TB-endemic country, may not require any intervention. Such findings may be due to either mycobacterial infection in the past or 'sarcoid reaction' to cancer. Although all patients should have their resected specimen sent for acid-fast bacilli culture and followed up until the culture results are reported, the initiation of the management of such patients as per existing lung cancer management guidelines does not affect their outcome adversely.

    Cancer development is often associated with chronic inflammation. To date, research into inflammation-induced cancer has largely focused on chemokines, cytokines, and their downstream targets. These inflammatory mediators may promote tumor growth, invasion, metastasis, and facilitate angiogenesis. However, the exact mechanisms by which inflammation promotes neoplasia remain unclear. Inflammatory bowel disease (IBD) is characterized by recurrent, idiopathic intestinal inflammation, the complications of which are potentially fatal. IBD incidence in Australia is 24.2 per 100,000 and its peak onset is in people aged 15 to 24 years. Symptoms include abdominal pain, cramps, bloody stool, and persistent diarrhoea or constipation and so seriously compromise quality of life. However, due to its unknown etiology, current treatment strategies combat the symptoms rather than the disease and are limited by inefficacy, toxicity, and adverse side-effects. IBD is also associated with an increased risk of colorectal cancer, for which treatment options are similarly limited. In recent years, there has been much interest in the therapeutic potential of mesenchymal stem cells (MSCs). However, whether MSCs suppress or promote tumor development is still contentious within the literature. Many studies indicate that MSCs exert anti-tumor effects and suppress tumor growth, whereas other studies report pro-tumor effects. Studies using MSCs as treatment for IBD have shown promising results in both animal models and human trials. However, as MSC treatment is still novel, the long-term risks remain unknown. This review aims to summarize the current literature on MSC treatment of inflammation-induced cancer, with a focus on colorectal cancer resulting from IBD.

    The TLC-Ag dressings, a combination of technology lipido-colloid and silver salts, are used to promote healing in wounds with risks or signs of local infection, thanks to the antimicrobial properties of the silver salts. Nanocrystalline silver dressings containing nanocrystalline silver, also used to improve wound healing, present both antimicrobial and anti-inflammatory effects. The aim of this study was to investigate the anti-inflammatory effects of TLC-Ag dressings in a model of chronic skin inflammation induced by repeated application of 12-O-tetradecanoylphorbol-13-acetate to the skin of hairless mice, in comparison with TLC dressing, Silcryst nanocrystalline dressing, desonide cream 0.05%, a corticoid cream used as positive control, and gauze. Daily treatments of the mice began 7 days after the start of induction of chronic skin inflammation and lasted for 7 days. A macroscopic score was performed daily during the treatment period until the mice killing on day 15 and skin samples were taken for histopathological analysis. TLC-Ag reduced significantly the macroscopic score of chronic skin inflammation from day 10 in comparison with gauze and TLC dressing, similarly to Silcryst nanocrystalline dressing and desonide cream, which presented the best anti-inflammatory effects. No significant differences were observed between TLC dressing and gauze. TLC-Ag reduced significantly the microscopic score of chronic skin inflammation in comparison with TLC dressing and gauze, similarly to Silcryst nanocrystalline dressing but significantly less than desonide cream. These results demonstrate that TLC-Ag dressings present significant anti-inflammatory effects on chronic skin inflammation. They can improve wound healing, due to both the antimicrobial and anti-inflammatory properties. © 2013 Japanese Dermatological Association.

  11. Postinjury Inflammation and Organ Dysfunction.

    Sauaia, Angela; Moore, Frederick A; Moore, Ernest E

    2017-01-01

    The development of organ dysfunction (OD) is related to the intensity and balance between trauma-induced simultaneous, opposite inflammatory responses. Early proinflammation via innate immune system activation may cause early OD, whereas antiinflammation, via inhibition of the adaptive immune system and apoptosis, may induce immunoparalysis, impaired healing, infections, and late OD. Patients discharged with low-level OD may develop the persistent inflammation-immunosuppression catabolism syndrome. Although the incidence of multiple organ failure has decreased over time, it remains morbid, lethal, and resource intensive. However, single OD, especially acute lung injury, remains frequent. Treatment is limited, and prevention remains the mainstay strategy. Copyright © 2016 Elsevier Inc. All rights reserved.

  12. Insulin resistance and chronic inflammation

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Insulin resistance is a condition of reduced biological response to insulin. Growing evidence indicates the role of the chronic low-grade inflammatory response in the pathogenesis of insulin resistance. Adipose tissue in obesity is characterized by increased lipolysis with the excessive release of free fatty acids, and is also a source of proinflammatory cytokines. Both these factors may inhibit insulin action. Proinflammatory cytokines exert their effect by stimulating major inflammatory NFκB and JNK pathways within the cells. Inflammatory processes in other insulin responsive tissues may also play a role in inducing insulin resistance. This paper is an overview of the chronic low-grade inflammation in adipose tissue, skeletal muscle, liver and endothelial cells during the development of insulin resistance.

  13. Liver inflammation during monocrotaline hepatotoxicity

    International Nuclear Information System (INIS)

    Copple, Bryan L.; Ganey, Patricia E.; Roth, Robert A.

    2003-01-01

    Monocrotaline (MCT) is a pyrrolizidine alkaloid (PA) plant toxin that causes hepatotoxicity in humans and animals. Human exposure occurs from consumption of contaminated grains and herbal teas and medicines. Intraperitoneal injection (i.p.) of 300 mg/kg MCT in rats produced time-dependent hepatic parenchymal cell (HPC) injury beginning at 12 h. At this time, an inflammatory infiltrate consisting of neutrophils (PMNs) appeared in areas of hepatocellular injury, and activation of the coagulation system occurred. PMN accumulation was preceded by up-regulation of the PMN chemokines cytokine-induced neutrophil chemoattractant-1 (CINC-1) and macrophage inflammatory protein-2 (MIP-2) in the liver. The monocyte chemokine, monocyte chemoattractant protein-1 (MCP-1), was also upregulated. Inhibition of Kupffer cell function with gadolinium chloride (GdCl 3 ) significantly reduced CINC-1 protein in plasma after MCT treatment but had no effect on hepatic PMN accumulation. Since inflammation can contribute to either pathogenesis or resolution of tissue injury, we explored inflammatory factors as a contributor to MCT hepatotoxicity. To test the hypothesis that PMNs contribute to MCT-induced HPC injury, rats were depleted of PMNs with a rabbit anti-PMN serum prior to MCT treatment. Anti-PMN treatment reduced hepatic PMN accumulation by 80% but had no effect on MCT-induced HPC injury or activation of the coagulation system. To test the hypothesis that Kupffer cells and/or tumor necrosis factor-α (TNF-α) are required for MCT-induced HPC injury, rats were treated with either GdCl 3 to inhibit Kupffer cell function or pentoxifylline (PTX) to prevent synthesis of TNF-α. Neither treatment prevented MCT-induced HPC injury. Results from these studies suggest that PMNs, Kupffer cells and TNF-α are not critical mediators of MCT hepatotoxicity. Accordingly, although inflammation occurs in the liver after MCT treatment, it is not required for HPC injury and possibly occurs secondary to

    In this study, we evaluated the 12-O-tetradecanoyl-phorbol-13-acetate (TPA)-induced acute and chronic inflammation in living mice by PET imaging of TNF-{alpha} and integrin {alpha}{sub v}{beta}{sub 3} expression. TPA was topically applied to the right ear of BALB/c mice every other day to create the inflammation model. {sup 64}Cu-DOTA-etanercept and {sup 64}Cu-DOTA-E{l_brace}E[c(RGDyK)]{sub 2}{r_brace}{sub 2} were used for PET imaging of TNF-{alpha} and integrin {alpha}{sub v}{beta}{sub 3} expression in both acute and chronic inflammation. Hematoxylin and eosin staining, ex vivo autoradiography, direct tissue sampling, and immunofluorescence staining were also performed to confirm the non-invasive PET imaging results. The ear thickness increased significantly and the TNF-{alpha} level more than tripled after a single TPA challenge. MicroPET imaging using {sup 64}Cu-DOTA-etanercept revealed high activity accumulation in the inflamed ear, reaching 11.1 {+-} 1.3, 13.0 {+-} 2.0, 10.9 {+-} 1.4, 10.2 {+-} 2.2%ID/g at 1, 4, 16, and 24 h post injection, respectively (n = 3). Repeated TPA challenges caused TPA-specific chronic inflammation and reduced {sup 64}Cu-DOTA-etanercept uptake due to lowered TNF-{alpha} expression. {sup 64}Cu-DOTA-E{l_brace}E[c(RGDyK)]{sub 2}{r_brace}{sub 2} uptake in the chronically inflamed ears (after four and eight TPA challenges) was significantly higher than in the control ears and those after one TPA challenge. Immunofluorescence staining revealed increased integrin {beta}{sub 3} expression, consistent with the non-invasive PET imaging results using {sup 64}Cu-DOTA-E{l_brace}E[c(RGDyK)]{sub 2}{r_brace}{sub 2} as an integrin {alpha}{sub v} {beta}{sub 3}-specific radiotracer. Biodistribution and autoradiography studies further confirmed the quantification capability of microPET imaging.

    Breathing is a vital homeostatic behavior and must be precisely regulated throughout life. Clinical conditions commonly associated with inflammation, undermine respiratory function may involve plasticity in respiratory control circuits to compensate and maintain adequate ventilation. Alternatively, other clinical conditions may evoke maladaptive plasticity. Yet, we have only recently begun to understand the effects of inflammation on respiratory plasticity. Here, we review some of common models used to investigate the effects of inflammation and discuss the impact of inflammation on nociception, chemosensory plasticity, medullary respiratory centers, motor plasticity in motor neurons and respiratory frequency, and adaptation to high altitude. We provide new data suggesting glial cells contribute to CNS inflammatory gene expression after 24h of sustained hypoxia and inflammation induced by 8h of intermittent hypoxia inhibits long-term facilitation of respiratory frequency. We also discuss how inflammation can have opposite effects on the capacity for plasticity, whereby it is necessary for increases in the hypoxic ventilatory response with sustained hypoxia, but inhibits phrenic long term facilitation after intermittent hypoxia. This review highlights gaps in our knowledge about the effects of inflammation on respiratory control (development, age, and sex differences). In summary, data to date suggest plasticity can be either adaptive or maladaptive and understanding how inflammation alters the respiratory system is crucial for development of better therapeutic interventions to promote breathing and for utilization of plasticity as a clinical treatment.

    2017-09-20

    In this review, we summarize evidence on the risk factor psychological stress in the context of coronary heart disease (CHD) in humans and explore the role of inflammation as a potential underlying mechanism. While chronic stress increases the risk of incident CHD and poor cardiovascular prognosis, acute emotional stress can trigger acute CHD events in vulnerable patients. Evidence supporting a potential role for inflammation as a promising biological mechanism comes from population-based studies showing associations between chronic stress and increased inflammation. Similarly, experimental studies demonstrate acute stress-induced increases in inflammatory markers and suggest modulatory potential for pharmacological and biobehavioral interventions. So far, studies investigating patients with cardiovascular disease are few and the full sequence of events from stress to inflammation to CHD remains to be established. Psychological stress is an independent CHD risk factor associated with increased inflammation. Although promising, causality needs to be further explored.

An inactive form due to mutations or a constitutive high expression of NOD2 is associated with several inflammatory diseases, suggesting that balanced NOD2 signaling is critical for the maintenance of immune homeostasis. In this review, we discuss recent developments about the pathway and mechanisms of regulation of NOD2 and illustrate the principal functions of the gene, with particular emphasis on its central role in maintaining the equilibrium between intestinal microbiota and host immune responses to control inflammation. Furthermore, we survey recent studies illustrating the role of NOD2 in several inflammatory diseases, in particular, inflammatory bowel disease, of which it is the main susceptibility gene.

    Young African females are at an increased risk of HIV acquisition, and genital inflammation or the vaginal microbiome may contribute to this risk. We studied these factors in 168 HIV-negative South African adolescent females aged 16 to 22 years. Unsupervised clustering of 16S rRNA gene sequences revealed three clusters (subtypes), one of which was strongly associated with genital inflammation. In a multivariate model, the microbiome compositional subtype and hormonal contraception were significantly associated with genital inflammation. We identified 40 taxa significantly associated with inflammation, including those reported previously ( Prevotella , Sneathia , Aerococcus , Fusobacterium , and Gemella ) as well as several novel taxa (including increased frequencies of bacterial vaginosis-associated bacterium 1 [BVAB1], BVAB2, BVAB3, Prevotella amnii , Prevotella pallens , Parvimonas micra , Megasphaera , Gardnerella vaginalis , and Atopobium vaginae and decreased frequencies of Lactobacillus reuteri , Lactobacillus crispatus , Lactobacillus jensenii , and Lactobacillus iners ). Women with inflammation-associated microbiomes had significantly higher body mass indices and lower levels of endogenous estradiol and luteinizing hormone. Community functional profiling revealed three distinct vaginal microbiome subtypes, one of which was characterized by extreme genital inflammation and persistent bacterial vaginosis (BV); this subtype could be predicted with high specificity and sensitivity based on the Nugent score (≥9) or BVAB1 abundance. We propose that women with this BVAB1-dominated subtype may have chronic genital inflammation due to persistent BV, which may place them at a particularly high risk for HIV infection.

    Micronutrient homeostasis is a key factor in maintaining a healthy immune system. Zinc is an essential micronutrient that is involved in the regulation of the innate and adaptive immune responses. The main cause of zinc deficiency is malnutrition. Zinc deficiency leads to cell-mediated immune dysfunctions among other manifestations. Consequently, such dysfunctions lead to a worse outcome in the response towards bacterial infection and sepsis. For instance, zinc is an essential component of the pathogen-eliminating signal transduction pathways leading to neutrophil extracellular traps (NET) formation, as well as inducing cell-mediated immunity over humoral immunity by regulating specific factors of differentiation. Additionally, zinc deficiency plays a role in inflammation, mainly elevating inflammatory response as well as damage to host tissue. Zinc is involved in the modulation of the proinflammatory response by targeting Nuclear Factor Kappa B (NF-κB), a transcription factor that is the master regulator of proinflammatory responses. It is also involved in controlling oxidative stress and regulating inflammatory cytokines. Zinc plays an intricate function during an immune response and its homeostasis is critical for sustaining proper immune function. This review will summarize the latest findings concerning the role of this micronutrient during the course of infections and inflammatory response and how the immune system modulates zinc depending on different stimuli.

    Cardiovascular disease is the leading cause of morbidity and mortality in obese individuals. Obesity dramatically increases the risk of development of metabolic and cardiovascular disease. This risk appears to originate from disruption in adipose tissue function leading to a chronic inflammatory state and to dysregulation of the endocrine and paracrine actions of adipocyte-derived factors. These, in turn, impair vascular homeostasis and lead to endothelial dysfunction. An altered endothelial cell phenotype and endothelial dysfunction are common among all obesity-related complications. A crucial aspect of endothelial dysfunction is reduced nitric oxide (NO) bioavailability. A systemic pro-inflammatory state in combination with hyperglycemia, insulin resistance, oxidative stress and activation of the renin angiotensin system are systemic disturbances in obese individuals that contribute independently and synergistically to decreasing NO bioavailability. On the other hand, pro-inflammatory cytokines are locally produced by perivascular fat and act through a paracrine mechanism to independently contribute to endothelial dysfunction and smooth muscle cell dysfunction and to the pathogenesis of vascular disease in obese individuals. The promising discovery that obesity-induced vascular dysfunction is, at least in part, reversible, with weight loss strategies and drugs that promote vascular health, has not been sufficiently proved to prevent the cardiovascular complication of obesity on a large scale. In this review we discuss the pathophysiological mechanisms underlying inflammation and vascular damage in obese patients.

    From their phylogenetic and pharmacological classification it might be inferred that cannabinoid receptors and their endogenous ligands constitute a rather specialised and biologically distinct signalling system. However, the opposite is true and accumulating data underline how much the endocannabinoid system is intertwined with other lipid and non-lipid signalling systems. Endocannabinoids per se have many structural congeners, and these molecules exist in dynamic equilibria with different other lipid-derived mediators, including eicosanoids and prostamides. With multiple crossroads and shared targets, this creates a versatile system involved in fine-tuning different physiological and metabolic processes, including inflammation. A key feature of this 'expanded' endocannabinoid system, or 'endocannabinoidome', is its subtle orchestration based on interactions between a relatively small number of receptors and multiple ligands with different but partly overlapping activities. Following an update on the role of the 'endocannabinoidome' in inflammatory processes, this review continues with possible targets for intervention at the level of receptors or enzymes involved in formation or breakdown of endocannabinoids and their congeners. Although its pleiotropic character poses scientific challenges, the 'expanded' endocannabinoid system offers several opportunities for prevention and therapy of chronic diseases. In this respect, successes are more likely to come from 'multiple-target' than from 'single-target' strategies. Copyright © 2015 Elsevier B.V. All rights reserved.

  11. Preeclampsia: From Inflammation to Immunoregulation

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available Preeclampsia (PE affects 5% to 7% of pregnant women each year worldwide, accounts for up to 18% of maternal deaths in the United States each year, and is the number 1 cause of premature births. Preeclampsia is associated with hypertension after the 20th week of gestation with or without proteinuria, in conjunction with fetal growth restriction, maternal endothelial dysfunction, and chronic immune activation. The mechanisms leading to the development of PE are unclear. However, it is thought that shallow trophoblast invasion and insufficient remodeling of uterine spiral arteries result in placental ischemia. Consequently, an immune imbalance characterized by increases in proinflammatory CD4 + T cells and cytokines along with decreases in regulatory T cells and anti-inflammatory cytokines occurs. This imbalance leads to chronic inflammation and ensuing oxidative stress, proinflammatory cytokines, and autoantibodies. Studies performed in our laboratories, using the R educed U terine P erfusion P ressure (RUPP rat model of placental ischemia, have demonstrated a role for this immune imbalance to mediate PE pathophysiology and identified potential mechanisms of immunoregulation that may be of benefit in the treatment of PE. Therefore, the purpose of this commentary is to review studies demonstrating the positive effects of immunoregulatory factors in the RUPP rat model of PE. Restoration of the immune balance in PE may be a potential strategy for the development of therapeutic interventions that could improve maternal and fetal outcomes associated with this maternal syndrome.

  12. Red cell DAMPs and inflammation.

    Mendonça, Rafaela; Silveira, Angélica A A; Conran, Nicola

    2016-09-01

    Intravascular hemolysis, or the destruction of red blood cells in the circulation, can occur in numerous diseases, including the acquired hemolytic anemias, sickle cell disease and β-thalassemia, as well as during some transfusion reactions, preeclampsia and infections, such as those caused by malaria or Clostridium perfringens. Hemolysis results in the release of large quantities of red cell damage-associated molecular patterns (DAMPs) into the circulation, which, if not neutralized by innate protective mechanisms, have the potential to activate multiple inflammatory pathways. One of the major red cell DAMPs, heme, is able to activate converging inflammatory pathways, such as toll-like receptor signaling, neutrophil extracellular trap formation and inflammasome formation, suggesting that this DAMP both activates and amplifies inflammation. Other potent DAMPs that may be released by the erythrocytes upon their rupture include heat shock proteins (Hsp), such as Hsp70, interleukin-33 and Adenosine 5' triphosphate. As such, hemolysis represents a major inflammatory mechanism that potentially contributes to the clinical manifestations that have been associated with the hemolytic diseases, such as pulmonary hypertension and leg ulcers, and likely plays a role in specific complications of sickle cell disease such as endothelial activation, vaso-occlusive processes and tissue injury.

    2011-05-01

    Blood platelets have long been recognised to bring about primary haemostasis with deficiencies in platelet production and function manifesting in bleeding while upregulated function favourises arterial thrombosis. Yet increasing evidence indicates that platelets fulfil a much wider role in health and disease. First, they store and release a wide range of biologically active substances including the panoply of growth factors, chemokines and cytokines released from a-granules. Membrane budding gives rise to microparticles (MPs), another active participant within the blood stream. Platelets are essential for the innate immune response and combat infection (viruses, bacteria, micro-organisms). They help maintain and modulate inflammation and are a major source of pro-inflammatory molecules (e.g. P-selectin, tissue factor, CD40L, metalloproteinases). As well as promoting coagulation, they are active in fibrinolysis; wound healing, angiogenesis and bone formation as well as in maternal tissue and foetal vascular remodelling. Activated platelets and MPs intervene in the propagation of major diseases. They are major players in atherosclerosis and related diseases, pathologies of the central nervous system (Alzheimers disease, multiple sclerosis), cancer and tumour growth. They participate in other tissue-related acquired pathologies such as skin diseases and allergy, rheumatoid arthritis, liver disease; while, paradoxically, autologous platelet-rich plasma and platelet releasate are being used as an aid to promote tissue repair and cellular growth. The above mentioned roles of platelets are now discussed.

  16. Due process traditionalism.

    2008-06-01

    In important cases, the Supreme Court has limited the scope of "substantive due process" by reference to tradition, but it has yet to explain why it has done so. Due process traditionalism might be defended in several distinctive ways. The most ambitious defense draws on a set of ideas associated with Edmund Burke and Friedrich Hayek, who suggested that traditions have special credentials by virtue of their acceptance by many minds. But this defense runs into three problems. Those who have participated in a tradition may not have accepted any relevant proposition; they might suffer from a systematic bias; and they might have joined a cascade. An alternative defense sees due process traditionalism as a second-best substitute for two preferable alternatives: a purely procedural approach to the Due Process Clause, and an approach that gives legislatures the benefit of every reasonable doubt. But it is not clear that in these domains, the first-best approaches are especially attractive; and even if they are, the second-best may be an unacceptably crude substitute. The most plausible defense of due process traditionalism operates on rule-consequentialist grounds, with the suggestion that even if traditions are not great, they are often good, and judges do best if they defer to traditions rather than attempting to specify the content of "liberty" on their own. But the rule-consequentialist defense depends on controversial and probably false assumptions about the likely goodness of traditions and the institutional incapacities of judges.

    Lung inflammation is a pivotal phenomenon in the pathogenesis of cystic fibrosis. Inflammation can be measured and quantified within a research perspective, as well as in daily clinical practice. In this review paper, the "Inflammation Task Force" of the "Société Française de Mucoviscidose" has reviewed the literature regarding the various techniques currently available (bronchoalveolar lavage, sputum analysis, nasal wash and brushing, exhaled breath condensates, carbon monoxide and nitric oxide, and systemic measurements (plasma and urine)). The interpretation of all these determinations in children and adults is also discussed.

    Full Text Available Acetylcholine is the predominant parasympathetic neurotransmitter in the airways that regulates bronchoconstriction and mucus secretion. Recent findings suggest that acetylcholine regulates additional functions in the airways, including inflammation and remodelling during inflammatory airway diseases. Moreover, it has become apparent that acetylcholine is synthesized by nonneuronal cells and tissues, including inflammatory cells and structural cells. In this paper, we will discuss the regulatory role of acetylcholine in inflammation and remodelling in which we will focus on the role of the airway smooth muscle cell as a target cell for acetylcholine that modulates inflammation and remodelling during respiratory diseases such as asthma and COPD.

  20. Scaffolds to Control Inflammation and Facilitate Dental Pulp Regeneration

    In dentistry, the maintenance of a vital dental pulp is of paramount importance, as teeth devitalized by root canal treatment may become more brittle and prone to structural failure over time. Advanced carious lesions can irreversibly damage the dental pulp by propagating a sustained inflammatory response throughout the tissue. While the inflammatory response initially drives tissue repair, sustained inflammation has an enormously destructive effect on the vital pulp, eventually leading to total necrosis of the tissue and necessitating its removal. The implications of tooth devitalization have driven significant interest in the development of bioactive materials that facilitate the regeneration of damaged pulp tissues by harnessing the capacity of the dental pulp for self-repair. In considering the process by which pulpitis drives tissue destruction, it is clear that an important step in supporting the regeneration of pulpal tissues is the attenuation of inflammation. Macrophages, key mediators of the immune response, may play a critical role in the resolution of pulpitis due to their ability to switch to a pro-resolution phenotype. This process can be driven by the resolvins, a family of molecules derived from fatty acids that show great promise as therapeutic agents. In this review, we outline the importance of preserving the capacity of the dental pulp to self-repair through the rapid attenuation of inflammation. Potential treatment modalities, such as shifting macrophages to a pro-resolving phenotype with resolvins are described, and a range of materials known to support the regeneration of dental pulp are presented.

    2014-01-01

    Full Text Available The sensation of pain is an indication that something is wrong somewhere in the body. Pain and inflammation may be linked by cyclooxygenase (COX enzymes most especially COX 2 , which help in the synthesis of prostaglandins (PGs precisely PGE2 and PGF2a, found in high concentration at the inflammatory site. The released PGs either stimulate pain receptor or sensitized pain receptors to the action of other pain producing substances such as histamine, 5-hydroxytryptamine (5HT, bradykinin which initiate and cause the nerve cells to send electrical pain impulse to the brain. In the present review, an attempt is made to unveil the treatment approach adopted in the management of pain and inflammation as well as animal models used in evaluating herbal plants with analgesic and anti-inflammatory properties. The choice of the use of herbal medicine have been encouraged due to it availability, affordability, accessibility, and little or no side effect associated with it. However, the question remains can herbal therapy serves as an alternative to available conventional drugs. Different treatment options in the management of pain and inflammation have been highlighted.

    Welders are exposed to airborne particles from the welding environment and often develop symptoms work-related from the airways. A large fraction of the particles from welding are in the nano-size range. In this study we investigate if the welders' airways are affected by exposure to particles derived from gas metal arc welding in mild steel in levels corresponding to a normal welding day. In an exposure chamber, 11 welders with and 10 welders without work-related symptoms from the lower airways and 11 non-welders without symptoms, were exposed to welding fumes (1 mg/m 3 ) and to filtered air, respectively, in a double-blind manner. Symptoms from eyes and upper and lower airways and lung function were registered. Blood and nasal lavage (NL) were sampled before, immediately after and the morning after exposure for analysis of markers of oxidative stress. Exhaled breath condensate (EBC) for analysis of leukotriene B4 (LT-B4) was sampled before, during and immediately after exposure. No adverse effects of welding exposure were found regarding symptoms and lung function. However, EBC LT-B4 decreased significantly in all participants after welding exposure compared to filtered air. NL IL-6 increased immediately after exposure in the two non-symptomatic groups and blood neutrophils tended to increase in the symptomatic welder group. The morning after, neutrophils and serum IL-8 had decreased in all three groups after welding exposure. Remarkably, the symptomatic welder group had a tenfold higher level of EBC LT-B4 compared to the two groups without symptoms. Despite no clinical adverse effects at welding, changes in inflammatory markers may indicate subclinical effects even at exposure below the present Swedish threshold limit (8 h TWA respirable dust).

    2013-01-01

    Full Text Available Background: Chronic Kidney Disease (CKD is one of the most severe diseases worldwide. In patients affected by CKD, a progressive destruction of the nephrons is observed not only in structuralbut also in functional level. Atherosclerosis is a progressive disease of large and medium-sized arteries. It is characterized by the deposition of lipids and fibrous elements and is a common complication of the uremic syndrome because of the coexistence of a wide range of risk factors. High blood pressure, anaemia, insulin resistance, inflammation, high oxidative stress are some of the most common factors that cause cardiovascular disease and atherogenesis in patients suffering from End Stage Kidney Disease (ESRD. At the same time, the inflammatory process constitutes a common element in the apparition and development of CKD. A wide range of possible causes can justify the development of inflammation under uremic conditions. Such causes are oxidative stress, oxidation, coexistentpathological conditions as well as factors that are due to renal clearance techniques. Patients in ESRD and coronary disease usually show increased acute phase products. Pre-inflammatory cytokines, such as IL-6 and TNF-a, and acute phase reactants, such as CRP and fibrinogen, are closely related. The treatment of chronic inflammation in CKD is of high importance for the development ofthe disease as well as for the treatment of cardiovascular morbidity.Conclusions: The treatment factors focus on the use of renin-angiotensic system inhibitors, acetylsalicylic acid, statins and anti-oxidant treatment in order to prevent the action of inflammatorycytokines that have the ability to activate the mechanisms of inflammation.

    Full Text Available Skeletal muscle regeneration is a complex process orchestrated by multiple steps. Recent findings indicate that inflammatory responses could play central roles in bridging initial muscle injury responses and timely muscle injury reparation. The various types of immune cells and cytokines have crucial roles in muscle regeneration process. In this review, we briefly summarise the functions of acute inflammation in muscle regeneration. The translational potential of this article: Immune system is closely relevant to the muscle regeneration. Understanding the mechanisms of inflammation in muscle regeneration is therefore critical for the development of effective regenerative, and therapeutic strategies in muscular disorders. This review provides information for muscle regeneration research regarding the effects of inflammation on muscle regeneration.

    Full Text Available Adverse obstetric outcomes are determinants of neonatal mortality and serious morbidity, often leading to neurologic and developmental alterations in early childhood and/or adult life. Several studies have focused the relationships between maternal inflammation and diseases and those conditions.The role of oral inflammation and gingival diseases as factors with potential maternal and fetal detrimental effects on the outcomes of pregnancy is a relatively new area of investigation that has attracted a lot of interest and research in the last twenty years. The new evidences now strongly support a role for maternal infection and inflammation of the genital tract, as well as inflammation from sites distant from the pelvis, in the etiology of preterm birth. The aim of the present paper is to outline and summarize the current knowledge about the relations between oral biofilms, periodontal inflammation and the pathogenic mechanisms linking periodontal diseases with adverse pregnancy outcomes, concluding with some practical advices for clinicians on the prevention and control of the oral inflammation and the related adverse outcomes in pregnant patients. Proceedings of the 11th International Workshop on Neonatology and Satellite Meetings · Cagliari (Italy · October 26th-31st, 2015 · From the womb to the adultGuest Editors: Vassilios Fanos (Cagliari, Italy, Michele Mussap (Genoa, Italy, Antonio Del Vecchio (Bari, Italy, Bo Sun (Shanghai, China, Dorret I.

    Most companies do a thorough job of financial due diligence when they acquire other companies. But all too often, deal makers simply ignore or underestimate the significance of people issues in mergers and acquisitions. The consequences are severe. Most obviously, there's a high degree of talent loss after a deal's announcement. To make matters worse, differences in decision-making styles lead to infighting; integration stalls; and productivity declines. The good news is that human due diligence can help companies avoid these problems. Done early enough, it helps acquirers decide whether to embrace or kill a deal and determine the price they are willing to pay. It also lays the groundwork for smooth integration. When acquirers have done their homework, they can uncover capability gaps, points of friction, and differences in decision making. Even more important, they can make the critical "people" decisions-who stays, who goes, who runs the combined business, what to do with the rank and file-at the time the deal is announced or shortly thereafter. Making such decisions within the first 30 days is critical to the success of a deal. Hostile situations clearly make things more difficult, but companies can and must still do a certain amount of human due diligence to reduce the inevitable fallout from the acquisition process and smooth the integration. This article details the steps involved in conducting human due diligence. The approach is structured around answering five basic questions: Who is the cultural acquirer? What kind of organization do you want? Will the two cultures mesh? Who are the people you most want to retain? And how will rank-and-file employees react to the deal? Unless an acquiring company has answered these questions to its satisfaction, the acquisition it is making will be very likely to end badly.

  15. Inflammation and nutrition in renal insufficiency.

    2003-07-01

    Protein-energy malnutrition (PEM) and inflammation are common in patients with chronic kidney disease (CKD) and worsen as the CKD progresses toward the end-stage renal disease (ESRD). These conditions are major predictors of poor clinical outcome in kidney failure, as reflected by a strong association between hypoalbuminemia and cardiovascular disease (CVD). It has been suggested that inflammation is the cause of both PEM and CVD and, hence, the main link among these conditions, but these hypotheses are not well established. Increased release or activation of inflammatory cytokines, such as interleukin-6 or tumor necrosis factor alpha, may suppress appetite, cause muscle proteolysis and hypoalbuminemia, and may be involved in atherogenesis. Increasing serum levels of proinflammatory cytokines caused by reduced renal function, volume overload, oxidative or carbonyl stress, decreased levels of antioxidants, increased susceptibility to infection in uremia, and the presence of comorbid conditions may lead to inflammation in CKD patients. In hemodialysis patients, the exposure to dialysis tubing and dialysis membranes, poor quality of dialysis water, back-filtration or back-diffusion of contaminants, and foreign bodies in dialysis access maybe additional causes of inflammation. Similarly, episodes of overt or latent peritonitis, peritoneal dialysis (PD) catheter and its related infections, and constant exposure to PD solution may contribute to inflammation in these patients. The degree to which PEM in dialysis patients is caused by inflammation is not clear. Because both PEM and inflammation are strongly associated with each other and can change many nutritional measures and outcome concurrently in the same direction, the terms malnutrition-inflammation complex syndrome (MICS) and/or malnutrition-inflammation-atherosclerosis (MIA) have been suggested to denote the important contribution of both of these conditions to poor clinical outcome.

    2014-08-22

    Local peripheral injury activates satellite glial cells (SGCs) in sensory ganglia, which may contribute to chronic pain. We hypothesized that systemic inflammation affects sensory ganglia like local injury. We induced systemic inflammation in mice by injecting lipopolysaccharide (LPS) intraperitoneally, and characterized SGCs and neurons in dorsal root ganglia (DRG), using dye injection, calcium imaging, electron microscopy (EM), immunohistochemistry, and electrical recordings. Several days post-LPS, SGCs were activated, and dye coupling among SGCs increased 3-4.5-fold. EM showed abnormal growth of SGC processes and the formation of new gap junctions. Sensitivity of SGCs to ATP increased twofold, and neuronal excitability was augmented. Blocking gap junctions reduced pain behavior in LPS-treated mice. Thus, changes in DRG due to systemic inflammation are similar to those due to local injury, which may explain the pain in sickness behavior and in other systemic diseases. Copyright © 2014 IBRO.

  18. The Resolution of Inflammation: A Mathematical Model of Neutrophil and Macrophage Interactions

    KAUST Repository

    2014-07-23

    © 2014, Society for Mathematical Biology. There is growing interest in inflammation due to its involvement in many diverse medical conditions, including Alzheimer’s disease, cancer, arthritis and asthma. The traditional view that resolution of inflammation is a passive process is now being superceded by an alternative hypothesis whereby its resolution is an active, anti-inflammatory process that can be manipulated therapeutically. This shift in mindset has stimulated a resurgence of interest in the biological mechanisms by which inflammation resolves. The anti-inflammatory processes central to the resolution of inflammation revolve around macrophages and are closely related to pro-inflammatory processes mediated by neutrophils and their ability to damage healthy tissue. We develop a spatially averaged model of inflammation centring on its resolution, accounting for populations of neutrophils and macrophages and incorporating both pro- and anti-inflammatory processes. Our ordinary differential equation model exhibits two outcomes that we relate to healthy and unhealthy states. We use bifurcation analysis to investigate how variation in the system parameters affects its outcome. We find that therapeutic manipulation of the rate of macrophage phagocytosis can aid in resolving inflammation but success is critically dependent on the rate of neutrophil apoptosis. Indeed our model predicts that an effective treatment protocol would take a dual approach, targeting macrophage phagocytosis alongside neutrophil apoptosis.

  19. Adipose Tissue Remodeling as Homeostatic Inflammation

    Directory of Open Access Journals (Sweden)

    Michiko Itoh

    2011-01-01

    Full Text Available Evidence has accumulated indicating that obesity is associated with a state of chronic, low-grade inflammation. Obese adipose tissue is characterized by dynamic changes in cellular composition and function, which may be referred to as “adipose tissue remodeling”. Among stromal cells in the adipose tissue, infiltrated macrophages play an important role in adipose tissue inflammation and systemic insulin resistance. We have demonstrated that a paracrine loop involving saturated fatty acids and tumor necrosis factor-α derived from adipocytes and macrophages, respectively, aggravates obesity-induced adipose tissue inflammation. Notably, saturated fatty acids, which are released from hypertrophied adipocytes via the macrophage-induced lipolysis, serve as a naturally occurring ligand for Toll-like receptor 4 complex, thereby activating macrophages. Such a sustained interaction between endogenous ligands derived from parenchymal cells and pathogen sensors expressed in stromal immune cells should lead to chronic inflammatory responses ranging from the basal homeostatic state to diseased tissue remodeling, which may be referred to as “homeostatic inflammation”. We, therefore, postulate that adipose tissue remodeling may represent a prototypic example of homeostatic inflammation. Understanding the molecular mechanism underlying homeostatic inflammation may lead to the identification of novel therapeutic strategies to prevent or treat obesity-related complications.

    2017-01-01

    Several host-adapted pathogens and commensals have evolved mechanisms to evade the host innate immune system inducing a state of low-grade inflammation. Epidemiological studies have also documented the association of a subset of these microorganisms with chronic inflammatory disorders. In this review, we summarize recent studies demonstrating the role of the microbiota in chronic inflammatory diseases and discuss how specific microorganisms subvert or inhibit protective signaling normally induced by toll-like receptors (TLRs). We highlight our work on the oral pathogen Porphyromonas gingivalis and discuss the role of microbial modulation of lipid A structures in evasion of TLR4 signaling and resulting systemic immunopathology associated with atherosclerosis. P. gingivalis intrinsically expresses underacylated lipid A moieties and can modify the phosphorylation of lipid A, leading to altered TLR4 signaling. Using P. gingivalis mutant strains expressing distinct lipid A moieties, we demonstrated that expression of antagonist lipid A was associated with P. gingivalis -mediated systemic inflammation and immunopathology, whereas strains expressing agonist lipid A exhibited modest systemic inflammation. Likewise, mice deficient in TLR4 were more susceptible to vascular inflammation after oral infection with P. gingivalis wild-type strain compared to mice possessing functional TLR4. Collectively, our studies support a role for P. gingivalis -mediated dysregulation of innate and adaptive responses resulting in immunopathology and systemic inflammation. We propose that anti-TLR4 interventions must be designed with caution, given the balance between the protective and destructive roles of TLR signaling in response to microbiota and associated immunopathologies.

    Intra-abdominal schwannoma is a rare tumor entity. Although often detected incidentally, its diagnosis and surgical planning are difficult-as with all intramural intra-abdominal tumors. Puncturing is often not satisfying due to the inhomogeneous proliferation rates of different regions of the tumor. We describe the procedure using the example of a gastric schwannoma that was found incidentally. The leading symptom was perforation of a peptic stomach ulcer.

    Extracellular vesicles (EVs) secreted by mesenchymal stromal cells (MSCs) have been proposed to be a key mechanistic link in the therapeutic efficacy of cells in response to cellular injuries through paracrine effects. We hypothesize that inflammatory stimulation of MSCs results in the release of EVs that have greater anti-inflammatory effects. The present study evaluates the immunomodulatory abilities of EVs derived from inflammation-stimulated and naive MSCs (MSCEv + and MSCEv, respectively) isolated using a current Good Manufacturing Practice-compliant tangential flow filtration system. Detailed characterization of both EVs revealed differences in protein composition, cytokine profiles, and RNA content, despite similarities in size and expression of common surface markers. MSCEv + further attenuated release of pro-inflammatory cytokines in vitro when compared to MSCEv, with a distinctly different pattern of EV-uptake by activated primary leukocyte subpopulations. The efficacy of EVs was partially attributed to COX2/PGE 2 expression. The present study demonstrates that inflammatory stimulation of MSCs renders release of EVs that have enhanced anti-inflammatory properties partially due to COX2/PGE 2 pathway alteration.

  6. Neurobiology of inflammation-associated anorexia

    Directory of Open Access Journals (Sweden)

    Laurent Gautron

    2010-01-01

    Full Text Available Compelling data demonstrate that inflammation-associated anorexia directly results from the action of pro-inflammatory factors, primarily cytokines and prostaglandins E2, on the nervous system. For instance, the aforementioned pro-inflammatory factors can stimulate the activity of peripheral sensory neurons, and induce their own de novo synthesis and release into the brain parenchyma and cerebrospinal fluid. Ultimately, it results in the mobilization of a specific neural circuit that shuts down appetite. The present article describes the different cell groups and neurotransmitters involved in inflammation-associated anorexia and examines how they interact with neural systems regulating feeding such as the melanocortin system. A better understanding of the neurobiological mechanisms underlying inflammation-associated anorexia will help to develop appetite stimulants for cancer and AIDS patients.

    Free-living amebae appertaining to the genus Acanthamoeba, Naegleria and Balamuthia are the most prevalent protozoa found in the environment. These amebae have a cosmopolitan distribution in soil, air and water, providing multiple opportunities for contacts with humans and animals, although they only occasionally cause disease. Acanthamoeba spp. are the causative agent of granulomatous amebic encephalitis, a rare and often fatal disease of the central nervous system, and amebic keratitis, a painful disease of the eyes. Keratitis usually follows a chronic course due to the delay in diagnosis and subsequent treatment. The clear increase in Acanthamoeba keratitis in the last 20 years is related to the use and deficient maintenance of contact lenses, and to swimming while wearing them. The expected incidence is one case per 30,000 contact lens wearers per year, with 88% of cases occurring in persons wearing hydrogel lenses. This review presents information on the morphology, life-cycle and epidemiology of Acanthamoeba, as well as on diagnostic procedures (culture), appropriate antimicrobial therapy, and prevention measures.

    Voriconazole concentrations display a large variability, which cannot completely be explained by known factors. Inflammation may be a contributing factor, as inflammatory stimuli can change the activities and expression levels of cytochrome P450 isoenzymes. We explored the correlation between inflammation, reflected by C-reactive protein (CRP) concentrations, and voriconazole trough concentrations. A retrospective chart review of patients with at least one steady-state voriconazole trough concentration and a CRP concentration measured on the same day was performed. A total of 128 patients were included. A significantly (P voriconazole trough concentration was observed in patients with severe inflammation (6.2 mg/liter; interquartile range [IQR], 3.4 to 8.7 mg/liter; n = 20) than in patients with moderate inflammation (3.4 mg/liter; IQR, 1.6 to 5.4 mg/liter; n = 60) and in patients with no to mild inflammation (1.6 mg/liter; IQR, 0.8 to 3.0 mg/liter; n = 48). The patients in all three groups received similar voriconazole doses based on mg/kg body weight (P = 0.368). Linear regression analyses, both unadjusted and adjusted for covariates of gender, age, dose, route of administration, liver enzymes, and interacting coadministered medications, showed a significant association between voriconazole and CRP concentration (P voriconazole trough concentration increased by 0.015 mg/liter (unadjusted 95% confidence interval [CI], 0.011 to 0.020 mg/liter; adjusted 95% CI, 0.011 to 0.019 mg/liter). Inflammation, reflected by the C-reactive protein concentration, is associated with voriconazole trough concentrations. Further research is necessary to assess if taking the inflammatory status of a patient into account is helpful in therapeutic drug monitoring of voriconazole to maintain concentrations in the therapeutic window, thereby possibly preventing suboptimal treatment or adverse events.

    Full Text Available Portal venous thrombosis (PVT is a condition associated with high morbidity. The etiologies of PVT include intra-abdominal inflammation or infection, surgical intervention, abdominal malignancies such as hepatocellular carcinoma (HCC and pancreatic carcinoma, or abnormality in coagulation caused by various reasons such as liver cirrhosis. Management of PVT should be based on its etiology and the condition of the patient. We describe a cirrhotic patient with HCC who suffered from acute pancreatitis. PVT in the main trunk was detected at admission due to the episode of acute pancreatitis. The etiology of thrombosis was considered to be inflammation around the main portal trunk caused by pancreatitis rather than cirrhosis or HCC. We did not instigate any management for the thrombosis. Acute pancreatitis was relieved after conservative treatment. Follow-up imaging study performed 46 days after detection of thrombosis showed spontaneous complete resolution of the thrombus. Our experience may provide useful information for the management of such patients.

  10. Inflammation: a trigger for acute coronary syndrome

    SAGER, Hendrik B.; NAHRENDORF, Matthias

    2016-01-01

    Atherosclerosis is a chronic inflammatory disease of the vessel wall and a major cause of death worldwide. One of atherosclerosis’ most dreadful complications are acute coronary syndromes that comprise ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina. We now understand that inflammation substantially contributes to the initiation, progression, and destabilization of atherosclerosis. In this review, we will focus on the role of inflammatory leukocytes, which are the cellular protagonists of vascular inflammation, in triggering disease progression and, ultimately, the destabilization that causes acute coronary syndromes.

  11. Anesthetics Impact the Resolution of Inflammation

    2008-01-01

    Background Local and volatile anesthetics are widely used for surgery. It is not known whether anesthetics impinge on the orchestrated events in spontaneous resolution of acute inflammation. Here we investigated whether a commonly used local anesthetic (lidocaine) and a widely used inhaled anesthetic (isoflurane) impact the active process of resolution of inflammation. Methods and Findings Using murine peritonitis induced by zymosan and a systems approach, we report that lidocaine delayed and blocked key events in resolution of inflammation. Lidocaine inhibited both PMN apoptosis and macrophage uptake of apoptotic PMN, events that contributed to impaired PMN removal from exudates and thereby delayed the onset of resolution of acute inflammation and return to homeostasis. Lidocaine did not alter the levels of specific lipid mediators, including pro-inflammatory leukotriene B4, prostaglandin E2 and anti-inflammatory lipoxin A4, in the cell-free peritoneal lavages. Addition of a lipoxin A4 stable analog, partially rescued lidocaine-delayed resolution of inflammation. To identify protein components underlying lidocaine's actions in resolution, systematic proteomics was carried out using nanospray-liquid chromatography-tandem mass spectrometry. Lidocaine selectively up-regulated pro-inflammatory proteins including S100A8/9 and CRAMP/LL-37, and down-regulated anti-inflammatory and some pro-resolution peptides and proteins including IL-4, IL-13, TGF-â and Galectin-1. In contrast, the volatile anesthetic isoflurane promoted resolution in this system, diminishing the amplitude of PMN infiltration and shortening the resolution interval (Ri) ∼50%. In addition, isoflurane down-regulated a panel of pro-inflammatory chemokines and cytokines, as well as proteins known to be active in cell migration and chemotaxis (i.e., CRAMP and cofilin-1). The distinct impact of lidocaine and isoflurane on selective molecules may underlie their opposite actions in resolution of inflammation

    2014-01-01

    The lymphatic system is intimately linked to tissue fluid homeostasis and immune cell trafficking. These functions are paramount in the establishment and development of an inflammatory response. In the past decade, an increasing number of reports has revealed that marked changes, such as lymphangiogenesis and lymphatic contractile dysfunction occur in both vascular and nodal parts of the lymphatic system during inflammation, as well as other disease processes. This review provides a critical update on the role of the lymphatic system in disease process such as chronic inflammation and cancer and examines the changes in lymphatic functions the diseases cause and the influence these changes have on the progression of the diseases.

    Full Text Available Lysosomes were originally described in the early 1950s by de Duve who was also the first to recognize the importance of these organelles in human disease. We know now that lysosomes are involved in numerous biological processes, and abnormalities in lysosomal function may result in a broad range of diseases. This review will briefly discuss the role of lysosomes in inflammation and how disruption of normal lysosomal function in the lysosomal storage diseases (LSDs leads to abnormalities in inflammation and immunity.

  15. The outsider adverse event in transfusion: Inflammation.

    Hod, Eldad A; Godbey, Elizabeth A

    2016-01-01

    In order to maintain adequate inventories of red blood cells (RBCs) for transfusion, RBC units are refrigerator-stored for variable amounts of time prior to transfusion. A subset of RBCs is damaged during prolonged storage. Clearance of these damaged RBCs is hypothesized to induce an inflammatory response in the transfusion recipient. However, there is controversy over whether RBC transfusions are in fact associated with inflammation, and more generally, whether current standards for maximal RBC storage times are safe. We will explore the evidence for and against this outsider adverse event in transfusion: whether certain RBC transfusions do or do not cause inflammation. Copyright © 2016 Elsevier Masson SAS.

  17. Diabetes, Inflammation, Proinflammatory Cytokines, and Diabetic Nephropathy

    Directory of Open Access Journals (Sweden)

    Juan F. Navarro

    2006-01-01

    Full Text Available Diabetes and its complications have become a public health problem. Diabetic nephropathy is the main cause of renal failure. In spite of our higher knowledge on this complication, the intimate mechanisms leading to the development and progression of renal injury are not yet fully known. Activated innate immunity and inflammation are relevant factors in the pathogenesis of diabetes. Moreover, inflammation, and more specifically proinflammatory cytokines and other molecules with a relevant role within the inflammatory process, may be critical factors in the development of microvascular diabetic complications, including nephropathy. This new pathogenic perspective may lead to important new therapeutic considerations and new therapeutic goals for the treatment of diabetic nephropathy.

  18. Inflammation in CNS Neurodegenerative Diseases.

    2018-03-07

    Neurodegenerative diseases, the leading cause of morbidity and disability is gaining increased attention as it imposes a considerable socioeconomic impact, due in part to the ageing community. Neuronal damage is a pathological hallmark of Alzheimer's and Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease, spinocerebellar ataxia and multiple sclerosis, although such damage is also observed following neurotropic viral infections, stroke, genetic white matter diseases and paraneoplastic disorders. Despite the different aetiologies e.g. infections, genetic mutations, trauma and protein aggregations, neuronal damage is frequently associated with chronic activation of an innate immune response in the CNS. The growing awareness that the immune system is inextricably involved in shaping the brain during development as well as mediating damage but also regeneration and repair, has stimulated therapeutic approaches to modulate the immune system in neurodegenerative diseases. Here, we review the current understanding of how astrocytes and microglia, as well as neurons and oligodendrocytes, shape the neuroimmune response during development, and how aberrant responses that arise due to genetic or environmental triggers may predispose the CNS to neurodegenerative diseases. We discuss the known interactions between the peripheral immune system and the brain, and review the current concepts on how immune cells enter and leave the CNS. A better understanding of neuroimmune interactions during development and disease will be key to further manipulating these responses and the development of effective therapies to improve quality of life, and reduce the impact of neuroinflammatory and degenerative diseases.

    2017-08-01

    Full Text Available Aging is the greatest risk factor for developing chronic diseases. Inflamm-aging, the age-related increase in low-grade chronic inflammation, may be a common link in age-related diseases. This review summarizes recent published data on potential cellular and molecular mechanisms of the age-related increase in inflammation, and how these contribute to decreased humoral immune responses in aged mice and humans. Briefly, we cover how aging and related inflammation decrease antibody responses in mice and humans, and how obesity contributes to the mechanisms for aging through increased inflammation. We also report data in the literature showing adipose tissue infiltration with immune cells and how these cells are recruited and contribute to local and systemic inflammation. We show that several types of immune cells infiltrate the adipose tissue and these include macrophages, neutrophils, NK cells, innate lymphoid cells, eosinophils, T cells, B1, and B2 cells. Our main focus is how the adipose tissue affects immune responses, in particular B cell responses and antibody production. The role of leptin in generating inflammation and decreased B cell responses is also discussed. We report data published by us and by other groups showing that the adipose tissue generates pro-inflammatory B cell subsets which induce pro-inflammatory T cells, promote insulin resistance, and secrete pathogenic autoimmune antibodies.

  1. The Immune System in Tissue Environments Regaining Homeostasis after Injury: Is "Inflammation" Always Inflammation?

    Science.gov (United States)

    Kulkarni, Onkar P; Lichtnekert, Julia; Anders, Hans-Joachim; Mulay, Shrikant R

    2016-01-01

    Inflammation is a response to infections or tissue injuries. Inflammation was once defined by clinical signs, later by the presence of leukocytes, and nowadays by expression of "proinflammatory" cytokines and chemokines. But leukocytes and cytokines often have rather anti-inflammatory, proregenerative, and homeostatic effects. Is there a need to redefine "inflammation"? In this review, we discuss the functions of "inflammatory" mediators/regulators of the innate immune system that determine tissue environments to fulfill the need of the tissue while regaining homeostasis after injury.

  2. Addisonian Crisis due to Metastatic Adenocarcinoma in a Pygmy Goat

    Directory of Open Access Journals (Sweden)

    Nora Nogradi

    2013-01-01

    Full Text Available A 15-year-old Pygmy doe was evaluated for acute onset of lethargy, anorexia, and weakness. Adrenal insufficiency was diagnosed based on physical exam findings, blood work abnormalities (hyponatremia, hyperkalemia, azotemia, and hypoglycemia, and lack of cortisol response to the ACTH stimulation test. Abdominal ultrasound exam revealed an intact urinary tract and multiple bilateral peri-renal masses. The doe was treated with intravenous fluid therapy aimed at correcting the electrolyte abnormalities and intravenous corticosteroids. She responded favorably to medical therapy in 24 hours, with dramatic improvement in attitude and appetite. Fluid therapy was discontinued, and the doe was discharged from the hospital on steroid supplementation. She deteriorated rapidly and died at home 36 hours after discharge. Necropsy results revealed metastatic adenocarcinoma originating from the uterus that infiltrated the urinary bladder, the region of the adrenal glands, the left and right renal lymph nodes, the left kidney, the caudal vena cava, the submandibular lymph nodes, the diaphragm, the lungs, and the omentum. Addison’s syndrome in ruminants should be considered as an uncommon sequel of intra-abdominal neoplastic processes.

  4. Infection, inflammation and exercise in cystic fibrosis

    Science.gov (United States)

    2013-01-01

    Regular exercise is positively associated with health. It has also been suggested to exert anti-inflammatory effects. In healthy subjects, a single exercise session results in immune cell activation, which is characterized by production of immune modulatory peptides (e.g. IL-6, IL-8), a leukocytosis and enhanced immune cell functions. Upon cessation of exercise, immune activation is followed by a tolerizing phase, characterized by a reduced responsiveness of immune cells. Regular exercise of moderate intensity and duration has been shown to exert anti-inflammatory effects and is associated with a reduced disease incidence and viral infection susceptibility. Specific exercise programs may therefore be used to modify the course of chronic inflammatory and infectious diseases such as cystic fibrosis (CF). Patients with CF suffer from severe and chronic pulmonary infections and inflammation, leading to obstructive and restrictive pulmonary disease, exercise intolerance and muscle cachexia. Inflammation is characterized by a hyper-inflammatory phenotype. Patients are encouraged to engage in exercise programs to maintain physical fitness, quality of life, pulmonary function and health. In this review, we present an overview of available literature describing the association between regular exercise, inflammation and infection susceptibility and discuss the implications of these observations for prevention and treatment of inflammation and infection susceptibility in patients with CF.

  13. Mechanisms Linking Inflammation to Insulin Resistance

    Directory of Open Access Journals (Sweden)

    Li Chen

    2015-01-01

    Full Text Available Obesity is now widespread around the world. Obesity-associated chronic low-grade inflammation is responsible for the decrease of insulin sensitivity, which makes obesity a major risk factor for insulin resistance and related diseases such as type 2 diabetes mellitus and metabolic syndromes. The state of low-grade inflammation is caused by overnutrition which leads to lipid accumulation in adipocytes. Obesity might increase the expression of some inflammatory cytokines and activate several signaling pathways, both of which are involved in the pathogenesis of insulin resistance by interfering with insulin signaling and action. It has been suggested that specific factors and signaling pathways are often correlated with each other; therefore, both of the fluctuation of cytokines and the status of relevant signaling pathways should be considered during studies analyzing inflammation-related insulin resistance. In this paper, we discuss how these factors and signaling pathways contribute to insulin resistance and the therapeutic promise targeting inflammation in insulin resistance based on the latest experimental studies.

    Airway infection and inflammation play major roles in the progression of cystic fibrosis (CF) lung disease. In patients with mild disease, airway inflammation is a clinically relevant and often underdiagnosed feature. Lung function, sputum cell counts, and cytokine profiles in CF with mild disease might be different in patients with and without involvement of small airway disease (SAD). Patients with mild CF (n=32) and 22 healthy controls were enrolled in this study. Patients with CF were assigned to two groups: (1) patients without SAD (n=19, median age 12.3years, MEF 25 >50% predicted), and (2) patients with SAD (n=13 median age, 13.2years, MEF 25 inflammation compared to controls as indicated by elevated levels of sputum biomarkers like total cells, neutrophils, and IL6. Our study demonstrated that patients with CF with mild disease defined by lung function might be further endotyped according to their involvement of SAD. In patients with CF and SAD, airway neutrophilic inflammation is more pronounced and is in part distinct from that seen in patients without SAD. Copyright © 2016 European Cystic Fibrosis Society.

    2010-07-01

    Full Text Available Abstract Background The aetiology and clinical significance of troponin release following endurance exercise is unclear but may be due to transient myocardial inflammation. Cardiovascular magnetic resonance (CMR affords us the opportunity to evaluate the presence of myocardial inflammation and focal fibrosis and is the ideal imaging modality to study this hypothesis. We sought to correlate the relationship between acute bouts of ultra endurance exercise leading to cardiac biomarkers elevation and the presence of myocardial inflammation and fibrosis using CMR. Methods 17 recreation athletes (33.5 +/- 6.5 years were studied before and after a marathon run with troponin, NTproBNP, and CMR. Specific imaging parameters to look for inflammation included T2 weighted images, and T1 weighted spin-echo images before and after an intravenous gadolinium-DTPA to detect myocardial hyperemia secondary to inflammation. Late gadolinium imaging was performed (LGE to detect any focal regions of replacement fibrosis. Results Eleven of the 17 participant had elevations of TnI above levels of cut off for myocardial infarction 6 hrs after the marathon (0.075 +/- 0.02, p = 0.007. Left ventricular volumes were reduced post marathon and a small increase in ejection fraction was noted (64+/- 1% pre, 67+/- 1.2% post, P = 0.014. Right ventricular volumes, stroke volume, and ejection fraction were unchanged post marathon. No athlete fulfilled criteria for myocardial inflammation based on current criteria. No regions of focal fibrosis were seen in any of the participants. Conclusion Exercise induced cardiac biomarker release is not associated with any functional changes by CMR or any detectable myocardial inflammation or fibrosis.

    Psychological distress may contribute to chronic activation of acute-phase inflammation. The current study investigated how financial stressors influence psychosocial functioning and inflammation. This study examined a) the direct relations between financial stress and inflammation; b) whether the relationships between financial stress and inflammation are mediated in part by negative interpersonal events, psychological distress, and psychological well-being; and c) whether social standing in one's community moderates the relations between financial stress and psychological distress, psychological well-being, and markers of inflammation (interleukin-6 [IL-6] and C-reactive protein). Stressful financial and interpersonal events over the previous year, perceived social status, indices of psychological well-being and distress, and levels of IL-6 and C-reactive protein were assessed in a community sample of 680 middle-aged adults (ages 40-65 years). Structural equation modeling analyses revealed significant relations among financial stress, interpersonal stress, and psychological distress and well-being, and complex relationships between these variables and inflammatory markers. Psychological well-being mediated the association between financial stress and IL-6 ([mediation] ab = 0.012, standard error [SE] = 0.006, p = .048). Furthermore, individuals with higher perceived social standing within their communities exhibited a stronger relation between negative financial events and both interpersonal stressors (interaction B = 0.067, SE = 0.017, p stress demonstrates complex relations with inflammation, due partly to psychological well-being and social perceptions. Findings are discussed with regard to the social context of stress and physiological factors pertinent to stress adaptation and inflammation.

  17. Clinical Management of Acute Portal/Mesenteric Vein Thrombosis

    Lang, Sven A.; Loss, Martin; Wohlgemuth, Walter A.; Schlitt, Hans J.

    2014-01-01

    Background Acute thrombosis of the portal vein (PV) and/or the mesenteric vein (MV) is a rare but potentially life-threatening disease. A multitude of risk factors for acute portal vein thrombosis (PVT)/mesenteric vein thrombosis (MVT) have been identified, including liver cirrhosis, malignancy, coagulation disorders, intra-abdominal infection/inflammation, and postoperative condition. Methods This article analyses the treatment options for acute PVT/MVT. Results Initially, the clinical management should identify patients with an intra-abdominal focus requiring immediate surgical intervention (e.g. bowel ischaemia). Subsequently, emphasis is placed on the recanalization of the PV/MV or at least the prevention of thrombus extension to avoid long-term complications of portal hypertension. Several therapeutic options are currently available, including anticoagulation therapy, local/systemic thrombolysis, interventional or surgical thrombectomy, and a combination of these procedures. Due to the lack of prospective randomized studies, a comparison between these therapeutic approaches regarding the efficacy of PV/MV recanalization is difficult, if not impossible. Conclusion In patients with acute PVT/MVT, an individualized treatment based on the clinical presentation, the underlying disease, the extent of the thrombosis, and the patients' comorbidities is mandatory. Therefore, these patients should be considered for an interdisciplinary therapy in specialized centres with the option to utilise all therapeutic approaches currently available. PMID:26285602

  18. Role of Smooth Muscle in Intestinal Inflammation

    Directory of Open Access Journals (Sweden)

    Stephen M Collins

    1996-01-01

    Full Text Available The notion that smooth muscle function is altered in inflammation is prompted by clinical observations of altered motility in patients with inflammatory bowel disease (IBD. While altered motility may reflect inflammation-induced changes in intrinsic or extrinsic nerves to the gut, changes in gut hormone release and changes in muscle function, recent studies have provided in vitro evidence of altered muscle contractility in muscle resected from patients with ulcerative colitis or Crohn’s disease. In addition, the observation that smooth muscle cells are more numerous and prominent in the strictured bowel of IBD patients compared with controls suggests that inflammation may alter the growth of intestinal smooth muscle. Thus, inflammation is associated with changes in smooth muscle growth and contractility that, in turn, contribute to important symptoms of IBD including diarrhea (from altered motility and pain (via either altered motility or stricture formation. The involvement of smooth muscle in this context may be as an innocent bystander, where cells and products of the inflammatory process induce alterations in muscle contractility and growth. However, it is likely that intestinal muscle cells play a more active role in the inflammatory process via the elaboration of mediators and trophic factors, including cytokines, and via the production of collagen. The concept of muscle cells as active participants in the intestinal inflammatory process is a new concept that is under intense study. This report summarizes current knowledge as it relates to these two aspects of altered muscle function (growth and contractility in the inflamed intestine, and will focus on mechanisms underlying these changes, based on data obtained from animal models of intestinal inflammation.

    Background Air pollution has consistently been associated with increased morbidity and mortality due to respiratory and cardiovascular disease. Underlying biological mechanisms are not entirely clear, and hemostasis and inflammation are suggested to be involved. Objectives Our aim was to study the association of the variation in local concentrations of airborne particulate matter (PM) with aerodynamic diameter < 10 μm, carbon monoxide, nitrogen monoxide, nitrogen dioxide, and ozone with platelet aggregation, thrombin generation, fibrinogen, and C-reactive protein (CRP) levels in healthy individuals. Methods From 40 healthy volunteers, we collected 13 consecutive blood samples within a 1-year period and measured light-transmittance platelet aggregometry, thrombin generation, fibrinogen, and CRP. We performed regression analysis using generalized additive models to study the association between the hemostatic and inflammatory variables, and local environmental concentrations of air pollutants for time lags within 24 hr before blood sampling or 24–96 hr before blood sampling. Results In general, air pollutants were associated with platelet aggregation [average, +8% per interquartile range (IQR), p < 0.01] and thrombin generation (average, +1% per IQR, p < 0.05). Platelet aggregation was not affected by in vitro incubation of plasma with PM. We observed no relationship between any of the air pollutants and fibrinogen or CRP levels. Conclusions Air pollution increased platelet aggregation as well as coagulation activity but had no clear effect on systemic inflammation. These prothrombotic effects may partly explain the relationship between air pollution and the risk of ischemic cardiovascular disease. PMID:19590696

    The macrophage is a prominent inflammatory cell in wounds, but its role in healing remains incompletely understood. Macrophages have been described to have many functions in wounds, including host defense, the promotion and resolution of inflammation, the removal of apoptotic cells, and the support of cell proliferation and tissue restoration following injury. Recent studies suggest that macrophages exist in several different phenotypic states within the healing wound, and that the influence of these cells on each stage of repair varies with the specific phenotypes. While the macrophage is beneficial to the repair of normally healing wounds, this pleotropic cell type may promote excessive inflammation and/or fibrosis in certain circumstances. Emerging evidence suggests that macrophage dysfunction is a component of the pathogenesis of non-healing and poorly healing wounds. Due to advances in the understanding of this multi-functional cell, the macrophage continues to be an attractive therapeutic target both to reduce fibrosis and scarring, and to improve healing of chronic wounds.
