Does simulation booster impact retention of resuscitation procedural skills and teamwork? J Perinatol 2014; 34:664-8. [PMID: 24762413 DOI: 10.1038/jp.2014.72] [Citation(s) in RCA: 58] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2013] [Revised: 03/07/2014] [Accepted: 03/13/2014] [Indexed: 11/09/2022]
Abstract
OBJECTIVE The Neonatal Resuscitation Program (NRP) has transitioned to a simulation-based format. We hypothesized that immersive simulation differentially impacts similar trainee populations' resuscitation knowledge, procedural skill and teamwork behavior. STUDY DESIGN Residents from NICU and non-NICU programs were randomized to either control or a booster simulation 7 to 10 months after NRP. Procedural skill and teamwork behavior instruments were validated. Individual resident's resuscitation performance was assessed at 15 to 18 months. Three reviewers rated videos. RESULT Fifty residents were assessed. Inter-rater reliability was good for procedural skills (0.78) and team behavior (0.74) instruments. The intervention group demonstrated better procedural skills (71.6 versus 64.4) and teamwork behaviors (18.8 versus 16.2). The NICU program demonstrated better teamwork behaviors (18.6 versus 15.5) compared with non-NICU program. CONCLUSION A simulation-enhanced booster session 9 months after NRP differentiates procedural skill and teamwork behavior at 15 months. Deliberate practice with simulation enhances teamwork behaviors additively with residents' clinical resuscitation exposure.

Abstract
CONTEXT Low overnight urinary melatonin metabolite concentrations have been associated with increased risk for breast cancer among postmenopausal women. The Postmenopausal Women's Alcohol Study was a controlled feeding study to test the effects of low to moderate alcohol intake on potential risk factors for breast cancer including serum and urinary levels of hormones and other biomarkers. Previously, we observed significant increases in concentrations of serum estrone sulfate and dehydroepiandrosterone sulfate in participants after consumption of 15 or 30 g (one or two drinks) of alcohol per day. OBJECTIVE In the present analysis, we evaluated the relationship of alcohol consumption with 24-h urinary 6-sulfatoxymelatonin (6-SMT) concentration (micrograms per 24 h). DESIGN AND PARTICIPANTS Healthy postmenopausal women (n = 51) consumed a controlled diet plus each of three treatments (a nonalcoholic placebo beverage or 15 or 30 g alcohol/d) during three 8-wk periods in random order under conditions of weight maintenance. MEASURES 6-SMT was measured in 24-h urine samples that were collected at entry into the study (baseline) and at the midpoint (4 wk) and end (8 wk) of each of the three diet periods. RESULTS Concentration of 6-SMT was not significantly modified by the alcohol treatment after adjustment for body mass index, hours of sleep, daylight hours, and baseline level of 6-SMT. CONCLUSIONS These results suggest that low to moderate daily alcohol consumption does not significantly affect 24-h urinary levels of melatonin among healthy postmenopausal women.

Abstract
e20516 Background: An important objective of the patient self determination act is for patients to see their wishes fulfilled, particularly at the end of life. Studies by Tiernan et al have shown that up to 80% of patients prefer to die at home however only a small proportion of patients actually die at home. Our work on support care networks show that a large proportion of women with cancer rely on multiple persons for health care proxy roles and for primary support. Given this, we sought to determine whether conducting a formal family meeting predicts whether a patient's preferred place of death corresponds with their actual place of death. Methods: We conducted a retrospective review of 105 women seen at Women & Infants’ Hospital within the last 12 weeks of their death and stratified patients between those who had a documented family meeting and those who did not. Results: Seventy-two percent (n= 105) of the study sample had family meetings in the last 12 weeks of life. Of those who had family meetings, 61% of patients whose preference of place of death coincide with their actual place of death (p<0.0001). In the sample of patients whose wishes coincide with their family meetings (n=76), almost 60% died at home and 34% died at inpatient hospice. Of those who did not have family meetings, 89% had unknown preferences of place of death, 48% died at the nursing home, 24% died in the hospital and 24% died at home. These results reached statistical significance (p= 0.001). Conclusions: Women who had a family meeting within the last 12 weeks of life were significantly more likely to die at home or with hospice services as compared to those who did not. This highlights the importance of including a patient's support networks into any communication between those dying from cancer and their healthcare providers. A larger study is warranted to determine whether this experience is specific to women with terminal cancer or is applicable to all patients with cancer facing the end of life. No significant financial relationships to disclose.

Abstract
OBJECTIVE To measure the residues of spinosad and chlorhexidine in the tissues of sheep after treatment of blowfly strike. PROCEDURE Fourteen sheep with natural myiasis and 12 with artificial infestations of Lucilia cuprina larvae had the wool removed over their infestations and were treated with an aerosol wound dressing containing spinosad and chlorhexidine. Sheep were killed up to 14 days after treatment and residues of the chemicals measured in tissues. RESULTS Chlorhexidine was not detected in any tissue. Residues of spinosad were highest in fat, lowest in muscle and intermediate in liver and kidney. The highest residue detected was 0.2 mg/kg spinosad in perirenal fat 7 days after generous treatment of a sheep with a large fly strike. Residues of spinosad in fat peaked 3 to 7 days after treatment and 1 to 3 days after treatment in liver and kidney. CONCLUSION These studies present a realistic worst-case in struck sheep and at the highest dose studied, equivalent to 5.8 mg spinosad per kg body weight, the maximum residue detected of 0.2 mg/kg in peri-renal fat was 20% of the Australian maximum residue limit. Muscle, liver and kidney residues of spinosad were also below the Australian maximum residue limits at all times.

Abstract
OBJECTIVE To examine 4- to 6-year-old children's knowledge of their parents' home safety rules and to identify predictors of children's home injuries. METHODS Within the context of an interview, parents completed a home safety questionnaire in which they specified home safety rules, rated their child's compliance with each rule, explained not having rules, reported on maternal supervision, and reported on the frequency of their child's injuries. We evaluated children's knowledge of home safety rules by having them play a home safety game designed for this study. RESULTS Children spontaneously recalled only about half of their parents' home safety rules. Prompting resulted in their recognition of about 40% more rules. However, children's knowledge scores did not predict the frequency of their injuries. The best predictors of children's injuries were children's compliance with home safety rules and extent of parental supervision. CONCLUSIONS These findings suggest that interventions to promote young children's safety knowledge will not likely reduce childhood injuries unless children consistently comply with these rules or parents supervise children to ensure compliance.

Abstract
OBJECTIVE With publication of the Diabetes Quality Improvement Project (DQIP) measures, the Indian Health Service National Diabetes Program applied the DQIP format to its IHS Diabetes Care and Outcomes Audit for comparison and benchmarks. RESEARCH DESIGN AND METHODS Since 1986 the IHS Diabetes Care and Outcomes Audit has been conducted by medical record review in >75% of IHS and tribal facilities. Each year systematic random sample of charts is drawn from local diabetes registries. Chart reviews are conducted by, trained professionals according to standard definitions and instructions. Abstracted data are entered into a microcomputer-based epidemiologic software package. Local, regional, and national rates are constructed for each item. During the period 1995-1997, 150 facilities submitted data for compilation, representing participation from all 12 IHS administrative regions. The IHS Diabetes Care and Outcomes Audit collected virtually all of the DQIP measures, with the exception of LDL cholesterol (which was added to the record review in 1998). RESULTS In 1995, 1996, and 1997, a total of 9,557, 9,985, and 9,626 individuals, respectively, were included in the total IHS audit sample. The reviews for 1995, 1996, and 1997 revealed that of all subjects: 55, 65, and 80%, respectively, had more than one HbA1c test during the year (P < 0.001); 42, 38, and 34%, respectively; had a high-risk HbA1c (>9.5%) (P < 0.001); 83, 81, and 84%, respectively, were tested for macroproteinuria (P < 0.11) and 16, 17, and 23%, respectively were tested for microproteinuria (P < 0.001); total cholesterol was assessed in 80, 81, and 85%, respectively (P < 0.001), and corresponding proportions of those with values <5.17 mmol/l were 48, 50, and 52%, respectively; triglyceride values were measured for 75,75, and 80%, respectively (P < 0.001), and the corresponding median triglyceride levels were 199, 198, and 193 mg/dl, respectively (P < 0.001); the proportion of clients with a blood pressure <140/90 mmHg was 64, 64, and 66%, respectively (P < 0.05); 55, 56, and 55%, respectively, had a dilated eye exam (P < 0.053); and the proportion of clients who had a comprehensive foot exam were 59, 59, and 61%, respectively (P < 0.05). CONCLUSIONS The DQIP accountability and quality improvement measures could be easily applied to the IHS Diabetes Care and Outcomes Audit, and the process can prove to be practical. However, data alone are not sufficient to effect change. Use of the measures to ensure that the quality of care improves must also be stressed, because measuring alone will not guarantee such improvement.

Abstract
BACKGROUND Over 2% of the population suffer from schizophrenia and related psychoses. Virtually all sufferers now live in the community, and go to see their general practitioners. OBJECTIVE To overview recent developments in the presentation and causes of schizophrenia and its treatment with medication and psychosocial intervention. DISCUSSION The diagnostic boundaries of schizophrenia have become less distinct as aetiological and therapeutic similarities between schizoaffective and affective psychoses have emerged. The importance of specific symptom groups (positive, negative, cognitive, manic, depressed) with respect to brain mechanisms and response to treatment has been recognised. It is now thought that recognition of early phase illness and vigorous treatment aimed at relapse prevention may improve long term prognosis. Availability of new medications has improved outcomes. Patients with schizophrenia living in the community need a range of services best delivered through collaborative care between GPs, community and specialist services.

Abstract
BACKGROUND In Victoria, Australia, systematic assessment of outcomes in mental health services are being instituted. AIMS To carry out a large-scale field trial of the Health of the Nation Outcome Scales (HoNOS). METHOD 2137 clients were rated by mental health workers on the HoNOS, and about half were rated again within a few months. RESULTS While interrater reliability of the total score was satisfactory, that of some individual items was unacceptable. Significant associations with age and gender were found, and clients with non-psychotic disorders obtained higher (i.e. worse) ratings than those with psychotic disorders. There were relationships between service use and HoNOS total score. For the group as a whole, total scores had not changed at the second rating, but admissions and discharges were associated with increases and decreases in total score. Among clients in the community, there was no relationship between change in HoNOS total score and frequency of contacts. CONCLUSIONS Certain items, notably 11 and 12, were unreliable. The absence of evidence of sensitivity to change may be due to the short re-rating interval, little real change in the clients, or the characteristics of the scale itself.

Abstract
Sucrose is the photoassimilate transported from the leaves to the fruit of tomato yet the fruit accumulates predominantly glucose and fructose. Hydrolysis of sucrose entering the fruit can be accomplished by invertase or sucrose synthase. Early in tomato fruit development there is a transient increase in sucrose synthase activity and starch which is correlated with fruit growth and sink strength suggesting a regulatory role for sucrose synthase in sugar import. Using an antisense sucrose synthase cDNA under the control of a fruit-specific promoter we show that sucrose synthase activity can be reduced by up to 99% in young fruit without affecting starch or sugar accumulation. This result calls into question the importance of sucrose synthase in regulating sink strength in tomato fruit.

Abstract
Fifty-seven patients with failed sclerotherapy received a mesocaval interposition shunt with an externally supported, ringed polytetrafluoroethylene prosthesis of either 10 or 12 mm diameter. Thirty-one patients had Child-Pugh grade A disease and 26 grade B; all had a liver volume of 1000-2500 ml. Follow-up ranged from 16 months to 6 years 3 months. Three patients (5 per cent) died in the postoperative period. There were two postoperative recurrences of variceal haemorrhage and one recurrent bleed in the second year after surgery. The cumulative shunt patency rate was 95 per cent and the incidence of encephalopathy 9 per cent; the latter was successfully managed by protein restriction and/or lactulose therapy. The actuarial survival rate for the whole group at 6 years was 78 per cent, for those with Child-Pugh grade A 88 per cent and for grade B 67 per cent. Small-lumen mesocaval interposition shunting achieves portal decompression, preserves hepatopetal flow, has a low incidence of shunt thrombosis, prevents recurrent variceal bleeding and is not associated with significant postoperative encephalopathy.

Abstract
OBJECTIVES This paper examines differences between joiners and nonjoiners of a voluntary smokers' registry. METHODS A baseline prevalence survey was used to identify characteristics of smokers who joined or did not join a smokers' registry. RESULTS Communities varied significantly in registry enrollment rates. Heavy-smoking joiners expressed more desire to quit, were more likely to live with nonsmokers, and were older than nonjoiners. Light-to-moderate joiners smoked more, were more addicted to cigarettes, and expressed more desire to quit than nonjoiners. CONCLUSIONS Few baseline characteristics differentiated joiners from nonjoiners. Nonjoiners were significantly more likely to achieve cessation than joiners.

Abstract
BACKGROUND Few studies have compared vasoactive drugs with endoscopic sclerotherapy in the control of acute variceal haemorrhage. Octreotide is widely used for this purpose, but its value remains undetermined. AIMS To compare octreotide with endoscopic sclerotherapy for acute variceal haemorrhage. PATIENTS Consecutive patients with acute variceal haemorrhage. METHODS Patients were randomised at endoscopy to receive either a 48 hour intravenous infusion of 50 pg/h octreotide (n = 73), or emergency sclerotherapy (n = 77). RESULTS Overall control of bleeding and mortality was not significantly different between octreotide (85%, 62 patients) and sclerotherapy (82%, 63 patients) over the 48 hour trial period (relative risk of rebleeding 0.83; 95% confidence interval (CI) 0.38 to 1.82), irrespective of Child's grading or active bleeding at endoscopy. One major complication was observed in the sclerotherapy group (aspiration) and two in the octreotide group (pulmonary oedema, severe paralytic ileus). During 60 days of follow up there was an overall trend towards an increased mortality in the octreotide group which was not statistically significant (relative risk of dying at 60 days 1.91, 95% CI 0.97 to 3.78, p = 0.06). CONCLUSIONS The results of this study indicate that intravenous octreotide is as effective as injection sclerotherapy in the control of acute variceal bleeding, but further controlled trials are necessary to evaluate the safety of this treatment.

Abstract
Antigen-specific T-cell activation requires the engagement of the T-cell receptor (TCR) with antigen as well as the engagement of appropriate costimulatory molecules. One of the most important pathways of costimulation is the interaction of CD28 on the T cell with B7-1/B7-2 on antigen-presenting cells. In the present study, we have examined the in vivo effects of blocking the CD28:B7 T-cell costimulatory pathway by administration of mCTLA4-IgG in a murine model of allergic asthma. Mice were sensitized with ovalbumin and exposed to repeated ovalbumin inhalation challenges. In mice treated with a control antibody at the time of ovalbumin challenge a significant increase in the number of eosinophils (12.8 +/- 4.3 x 10(3) cells, P < 0.05) in the bronchoalveolar lavage (BAL) fluid and airway hyperresponsiveness to methacholine (49 +/- 15%, P < 0.05) was observed. In addition, serum levels of ovalbumin-specific IgE were significantly (P < 0.01) increased after ovalbumin challenge compared with saline challenge (1,133 +/- 261 experimental units [EU]/ml and 220 +/- 63 EU/ml, respectively). In mice treated with mCTLA4-IgG at the time of ovalbumin challenge, the infiltration of eosinophils into BAL fluid and the development of airway hyperresponsiveness to methacholine were completely inhibited. The upregulation of ovalbumin-specific IgE levels in serum was attenuated by mCTLA4-IgG treatment. Furthermore, addition of mCTLA4-IgG to cultures of parabronchial lymph node cells from sensitized mice inhibited the ovalbumin-induced interleukin-4 production. These data indicate the therapeutic potential of blocking T-lymphocyte costimulation by CTLA4-IgG as a possible immunosuppressive treatment for patients with allergic asthma.

Abstract
PURPOSE To identify key systems issues from the Indian Health Service (IHS) experience that must be addressed to improve metabolic control among patients with non-insulin-dependent diabetes mellitus (NIDDM) who were followed in primary care settings. DATA SOURCES Records of diabetic patients seen in IHS facilities in specific geographic regions from 1987 to 1994. STUDY SELECTION A representative sample of charts from each facility was reviewed yearly to measure key variables. The sampling frame was the number of diabetic patients currently active on the registry and the sample size calculated to measure a 10% change in selected practices at each facility. EXTRACTION Regional diabetes coordinators reviewed charts or trained local providers to sample and extract data in a standard format. RESULTS Regional data were examined to show trends in the performance of immunizations and foot examinations and in other variables such as hypertension and metabolic control. The percentage of diabetic patients who received a single dose of pneumococcal vaccine improved from 24% in 1987 to 1988 to 57% in 1994 (P < 0.01 for trend) among diabetic patients in Minnesota, Wisconsin, and Michigan. Rates of yearly comprehensive foot examination increased from 36% to 58% (P < 0.01 for trend) over the same period. In Montana and Wyoming, the percentage of diabetic patients with uncontrolled hypertension (defined as the mean of three systolic blood pressure measurements of > or = 140 mm Hg or diastolic pressure measurements > or = 90 mm Hg, or both, during the previous year) decreased from 36% in 1992 to 25% in 1993 after the regional diabetes coordinator emphasized hypertension control. In 1994, when less emphasis was placed on hypertension, 33% of the diabetic patients had uncontrolled hypertension. Estimates of metabolic control from records of diabetic patients in Washington, Oregon, and Idaho in 1994 showed that 29% of patients had excellent metabolic control (a hemoglobin A1c [HbA1c] level < or = 7.5% or mean blood glucose level < or = 9.2 mmol/L) within the past year; only 9% experienced poor control (a HbA1c level > 12% or mean blood glucose level > 18.9 mmol/L). CONCLUSIONS The IHS experience shows that standard, ongoing monitoring of key variables allows facilities to improve diabetes care. Simple, reliable methods of defining metabolic control combined with a feedback system in the primary care setting are needed to improve metabolic control in patients with NIDDM.

Abstract
Bleeding from oesophageal varices, oesophageal ulcers or oesophagitis is occasionally massive and difficult to control. Octreotide, a synthetic analogue of somatostin lowers portal pressure and collateral blood flow including that through varices, increases lower oesophageal sphincter pressure, and inhibits the gastric secretion of acid as well as pepsin. Our current experience suggests it is effective in controlling acute variceal haemorrhage. Therefore we have examined the efficacy of octreotide in the control of post-sclerotherapy bleeding from oesophageal varices, oesophageal ulcers and oesophagitis. During the study period 77 patients experienced a significant gastrointestinal bleed (blood pressure < 100 mm Hg, pulse > 100 beats per min or the need to transfuse 2 or more units of blood to restore the hemoglobin level) following injection sclerotherapy of oesophageal varices. The source of bleeding was varices in 42 patients, oesophageal ulcers in 31 and oesophagitis in 4. All patients received a continuous intravenous infusion of octreotide (50 micrograms/h) for between 40-140h. If bleeding was not controlled in the first 12h after commencing octreotide hourly bolus doses (50 micrograms) for 24h were superimposed on the continuous infusion. Haemorrhage was successfully controlled by an infusion of octreotide in 38 of the 42 patients with bleeding from varices, in 30 of 31 patients with oesophageal ulceration, and all patients with oesophagitis. In the 1 patient with persistent bleeding from oesophageal ulceration and in 2 of the 4 with continued haemorrhage from varices, haemostasis was achieved by hourly boluses of 50 micrograms octreotide for 24h in addition to the continuous infusion. No major complications were associated with octreotide administration. The results of this study clearly indicate that octreotide is a safe and effective treatment for the control of severe haemorrhage after technically successful injection of sclerotherapy.

Abstract
Oesophageal varices are abnormally dilated veins that develop beneath the mucosa of the lower oesophagus and upper stomach and cause profound gastrointestinal haemorrhage associated with a high mortality. Varices develop in the presence of protal hypertension, which, in Europe and the USA, is most commonly due to alcoholic cirrhosis of the liver. Alcoholic cirrhosis develops in 10-20% of chronic ethanol abusers as a result of prolonged hepatocyte damage, leading to centrilobular inflammation and fibrosis. The net effect on the portal venous system is an elevation of resistance, and/or increase of inflow, producing portal hypertension, and the development of collateral channels in the form of varices. Such parenchymal liver disease also causes ascites, clotting deficiencies, secondary malnutrition and hepatic encephalopathy, all of which contribute to the high mortality associated with variceal haemorrhage. Variceal bleeding is more likely to occur when the varices are large, long and numerous, with surface red markings, and may be precipitated to respiratory tract infection, non-steroidal anti-inflammatory drugs, alcohol, or may occur spontaneously. Once identified by endoscopy, the aims of management are to control the haemorrhage, to prevent recurrent haemorrhage, and to treat the underlying cause of portal hypertension. Attention to nutrition and long-term rehabilitation are particularly important in those alcoholic cirrhotic patients who survive.

Abstract
Immunoglobulin (Ig) E antibodies mediate allergic responses by binding to specific high affinity receptors, Fc epsilon RI, on mast cells and basophils. Previous studies have shown that the principal Fc epsilon RI binding site is located on the third constant domain, Fc epsilon 3, of IgE. Based on a model of the IgE Fc epsilon 3 (which is homologous to the second constant domain of IgG), homology scanning mutagenesis and replacement of individual residues were used to determine the specific amino acids of human IgE involved in binding to human Fc epsilon RI. The amino acids are localized in three loops, which form a putative ridge on the most exposed side of the Fc epsilon 3 domain of IgE and include Arg-408, Ser-411, Lys-415, Glu-452, Arg-465, and Met-469. The preponderance of charged residues suggests that IgE-Fc epsilon RI binding is mediated primarily by electrostatic interaction. Furthermore, it is possible to confer Fc epsilon RI binding to an IgG molecule by introducing these three IgE loops into the IgG C gamma 2 domain.

Abstract
A trans-spliced leader gene has been identified in the genomes of the potato cyst nematodes Globodera rostochiensis and G. pallida. The gene contains a 22-nt sequence identical to that of the leader sequence of Caenorhabditis elegans, a consensus splice donor site and a putative Sm antigen binding site. In common with other nematodes the spliced leader gene is present in tandem repeating units together with the 5S ribosomal RNA gene. Variation in the length of the intergenic spacer region has permitted the design of polymerase chain reaction primers which can be used to reveal repeat length variants diagnostic for G. rostochiensis and G. pallida and the Pa1 pathotype of G. pallida.

Abstract
High IgE responder BDF1 mice were immunized intraperitoneally (i.p.) with dinitrophenol4 (DNP4)-ovalbumin (OVA) in alum concomitant with intravenous (i.v.) administration of an anti-IgE monoclonal antibody (mAb). IgE levels were undetectable in mice treated with the anti-IgE antibody, whereas mice treated with isotype-matched irrelevant mAb had IgE levels comparable to that of untreated, immunized mice. Subsequent antigen challenges with DNP4-OVA, either at weekly or monthly intervals, failed to evoke an IgE response for greater than 2 months in mice treated with anti-IgE during the primary sensitization, even though the terminal half-life of the anti-IgE antibody was 7 days. This inhibition was specific for DNP4-OVA since the DNP4-OVA-suppressed mice were able to respond to keyhole limpet haemocyanin (KLH). To investigate the effects of antibody treatment at the cellular level, passive transfer experiments were performed. The primary DNP-specific IgE response of adoptive transfer recipient mice was the same whether the donor cells were from mice treated with IgG or anti-IgE. Transfer of enriched T- or B-cell populations indicated that T-cell help was not compromised by administration of the anti-IgE mAb. However, splenocytes from the anti-IgE-treated mice failed to synthesize IgE in vitro, and flow cytometric analysis of B cells from anti-IgE-treated mice showed a dose-dependent decrease in CD23+ cells following antibody treatment, which correlated with decreased serum IgE levels. Taken together, the results of these studies suggest that anti-IgE treatment suppresses IgE responses via effects on B cells rather than T cells, possibly through effects on CD23-dependent pathways.

Abstract
A female patient with a three year history of Crohn's disease of the colon developed myasthenia gravis. Despite diversion of the faecal stream by an ileostomy, and total colectomy, the patient had continuing problems with perineal and perianal abscesses and fistulas. Her myasthenia gravis became unresponsive to anti-cholinergics so a thymectomy was performed. The perineal and perianal disease improved subsequently. This case supports the theory that functional disturbances of the thymus may have a role in the pathogenesis of inflammatory bowel disease.

Abstract
Cross-linking of the high affinity IgE receptor (Fc epsilon RI) expressed on mast cells and basophils is essential for triggering anaphylaxis in vivo. Previously, other investigators have tried to produce competitive inhibitors using IgE peptide analogues and anti-IgE antibodies with limited success. To create a novel specific inhibitor of IgE that can block binding of IgE to Fc epsilon RI without the capacity to stimulate degranulation, we made an Fc epsilon RI-IgG immunoadhesin. The Fc epsilon RI-IgG was constructed by gene fusion of the extracellular portion of the human alpha-chain of Fc epsilon RI, which contains the high affinity binding site for IgE, with a truncated human IgG1 H chain C region. The Fc epsilon RI-IgG recognizes both human and murine IgE. Coincubation of Fc epsilon RI-IgG with murine IgE prevented sensitization of RBL-2H3 cells and the subsequent histamine release in response to anti-IgE. Similarly, when the Fc epsilon RI-IgG was preincubated with equimolar concentrations of either hyperimmune mouse sera or purified mouse IgE, it completely blocked the passive cutaneous anaphylaxis reaction in rats. Furthermore, i.v. administration of Fc epsilon RI-IgG following intracutaneous injection of serum from DNP-immunized mice was able to block the passive cutaneous anaphylaxis reaction in a time-dependent fashion. These results demonstrate that Fc epsilon RI-IgG is a potent inhibitor of IgE binding to intracutaneous mast cells in vivo and may prove clinically useful for the treatment of IgE-mediated disease.

Abstract
Fourteen patients with liver cirrhosis of differing severity participated in a one-dimensional chemical shift imaging 31P MRS study of the liver. Patients were divided into two groups according to the severity of their liver disease using Child's classification and the aminopyrine breath test (AB test). Seven normal volunteers without liver disease acted as controls. The phosphomonester (PME) peak in normal subjects was 4.77% (95% confidence interval, CI: 4.11-5.42) of total phosphorus. The PME peak was significantly elevated in both mild cirrhosis [5.80% (95% CI: 5.46-6.14), p = 0.0051, vs normal subjects] and severe cirrhosis [9.64% (95% CI: 8.71-10.57), p = 0.0002, vs normal subjects and p = 0.001, vs mild cirrhosis]. There was a significant negative linear correlation (r = 0.88, p < 0.01) of PME with the percentage dose of 14CO2 excreted over 2 h in the AB test. pH values in patients with mild cirrhosis [7.45 (95% CI: 7.35-7.55)] but not severe cirrhosis [7.36 (95% CI: 7.25-7.47)] were significantly elevated (p = 0.04) compared to normal subjects [7.29 (95% CI: 7.17-7.41)]. Comparison of the peak area of PME at TR = 0.5 s against that using TR = 5.0 s in cirrhotic liver suggested no reduction in T1 of phosphorus metabolites in cirrhosis. A relationship between the severity of liver cirrhosis and a relative increase in PME was demonstrated and this was not due to a reduction of T1. This study highlights the clinical potential of 31P MRS as a non-invasive means of assessing the severity of liver cirrhosis.

Abstract
Sixteen patients with persistent (n = 11) or recurrent (n = 5) variceal bleeding after injection
sclerotherapy and balloon tamponade were treated with an intravenous infusion of somatostatin 250μg/
h. Somatostatin infusion successfully controlled the bleeding in 15 of the 16 patients but one rebled after
72 h of treatment. In one patient with poor liver function (Child’s C) bleeding was not controlled by
somatostatin, further injection sclerotherapy or balloon tamponade of the oesophagus. The results of
this study, although uncontrolled and with a small number of patients, suggest that somatostatin is a very
effective treatment for the control of post-injection sclerotherapy variceal bleeding.

Abstract
Since previous reports have suggested that somatostatin may be of value in the control of acute variceal haemorrhage, we compared its efficacy with that of injection sclerotherapy in a randomised controlled clinical trial. Eighty consecutive patients with endoscopically-proven severe variceal bleeding were randomised to injection sclerotherapy (n = 41) or somatostatin (n = 39) given as a continuous infusion of 250 micrograms/h for 5 days plus daily bolus administration of 250 micrograms. The efficacy of injection sclerotherapy and somatostatin infusion in controlling haemorrhage and preventing rebleeding (censored at 5 days), mortality (censored at 28 days) and complications was compared. The aetiology of the portal hypertension and transfusion requirements was similar between the two groups, but there were more patients with severe liver disease (Child's C) in the somatostatin group. There was no significant difference between the two treatments in the initial (p = 1.0) or overall control of bleeding (p = 0.58). Furthermore, somatostatin was as effective as injection sclerotherapy in controlling bleeding in patients with severe liver disease or in those actively bleeding at the time of their endoscopy. The relative risk of rebleeding whilst receiving somatostatin compared to injection sclerotherapy was 1.39 [95% Confidence Interval (CI) 3.73; 0.52], but this was reduced to 0.98 (95% CI 0.37; 2.67) when readjusted for Child's grading, the only prognostic factor shown to be of significance. Mortality was not significantly different between the two groups of patients (p = 0.31). The relative risk of dying whilst receiving somatostatin compared to injection sclerotherapy was 1.6 (95% CI 3.93; 0.66) but was reduced to 1.03 (95% CI 0.47; 2.47) when adjusted for Child's grading, the only significant prognostic factor. Complications in the somatostatin group were minor and less frequent than after injection sclerotherapy. The results of this study indicate that somatostatin is a safe treatment, which is as effective an endoscopic injection sclerotherapy for acute variceal bleeding.
