Donation of kidneys. Medical Services Study Group of the Royal College of Physicians.

A survey of deaths from medical causes among hospital inpatients aged under 50 years in three health regions provided details of 1168 such deaths not caused by renal failure. Kidneys for transplantation were obtained from only 20 of these patients. In another 18 cases permission was refused or donation was impracticable. Ninety-eight of the deaths were due to subarachnoid haemorrhage and 38 to primary cerebral tumour, yet kidneys were obtained from only 11 and one of these patients respectively. Patients dying from subarachnoid haemorrhage are particularly suitable for donating their kidneys, but there is still a shortage of kidneys for transplantation because they are not harvested efficiently. Doctors seem to be reluctant to ask relatives'' permission to remove kidneys, and the arrangement of a donation is time consuming. Because transplant surgery is recognised as a specialist sphere, surgeons in other specialties may be reluctant to remove kidneys and come to rely on one transplant team covering a wide area. In an area such as Grampian, where a small population is served by one hospital containing all the major units, including accident and emergency and renal departments, it may be easier to arrange prompt donation and transplantation.     

Video Capsule Endoscopy in Patients with Chronic Abdominal Pain with or without Associated Symptoms: A Retrospective Study

Background

Chronic abdominal pain (CAP) is a common indication for gastroenterology referrals. More insidious causes of CAP isolated to the small bowel, such as malignancies and Crohn’s disease, are rising in incidence and causing more gastroenterologists to evaluate their patients with video capsule endoscopy (VCE). However, the role of VCE in patients with CAP is still unclear.

Aims

We assessed the efficacy of VCE in patients with CAP and whether it led to findings that contributed to disease management and meaningful interventions.

Methods

This retrospective study evaluated 607 capsule endoscopy studies at an open referral endoscopy unit. Ninety of the studies were for CAP. These studies were compared to those performed for other indications to compare diagnostic yield. In addition, we investigated whether VCE led to an intervention that improved clinical outcomes.

Results

Overall, the number of abnormal findings in CAP patients was significantly lower than VCE performed for other indications (24.4% vs 39.0%, respectively p = 0.009). When patients with CAP presented with other pertinent clinical findings (e.g. nausea, weight loss, anemia, history of in inflammatory bowel disease, etc.), the likelihood of an abnormal finding increased to a level that was not different from those who received VCE for other indications (27.1%, p = 0.10). The findings from VCE lead to changed management and improved outcomes in 16.2% of CAP patients with associated symptoms. However, the subgroup that benefited the most were those who had a prior history of Crohn’s disease. Patients with CAP who did not have any associated symptoms continued to have a significantly lower abnormal finding rate compared to those who received VCE for other indications (19.4%, p = 0.03) and VCE rarely led to a change in management that would improve outcomes (5.6%).

Conclusions

VCE for CAP has a lower rate of abnormal findings than other indications. However, VCE is a useful diagnostic tool that can help provide a possible etiology of CAP in patients with associated symptoms. However, a change in management from VCE is likely to be limited to those with a history of Crohn’s disease.     

Influence of Royal College of Radiologists' guidelines on referral from general practice. Royal College of Radiologists Working Party.

OBJECTIVE--To measure the effect on general practitioner referrals for radiography of introducing guidelines of good practice together with monitoring and peer review. DESIGN--Collection of referral data during 1 January 1989 to 31 December 1990. Guidelines were introduced on 1 January 1990. SETTING--Open access radiology services provided by one non-teaching district in England. SUBJECTS--144614 registered patients from 22 practices. MAIN OUTCOME MEASURES--Number of referrals per 1000 registered patients for radiography of the chest, skull, spine, abdomen, limbs, and joints and for barium investigation and excretion urography. RESULTS--Overall referrals fell from 88.4/1000 registered patients to 77.2/1000 after the guidelines were introduced. The commonest reasons for referral were for examination of the chest, spine, and limbs and joints and referrals for these fell by 9.4%, 17.5%, and 13.5% respectively. Referrals for skull radiography fell by 30% (from 241 to 168). CONCLUSIONS--By helping general practitioners to be more selective in their use of diagnostic radiology, the guidelines reduced the rate of referral and thus patients'' exposure to radiation.     

Royal College of Physicians and Surgeons of Canada: annual meeting draws over 2000 physicians

In a review of 19 years'' experience with inhalation of foreign bodies by children the 33 patients (mean age 28 months) were found to have presented most frequently with wheezing or coughing, or both, of recent onset, and to have decreased air entry, rhonchi or respiratory stridor, or a combination of these signs. Eighteen children had inhaled a nut, a pea or a bean. The other 15 had inhaled various organic and inorganic objects. All the children underwent bronchoscopy, and the foreign body was completely removed in 19 during the first procedure; the remainder required repeated bronchoscopy or direct surgical removal of the foreign body, or both. Permanent disability or death was not encountered. The findingsof the study indicate that early bronchoscopic removal is the preferred treatment when a child inhales a foreign body.     

Time delays in provision of thrombolytic treatment in six district hospitals. Joint Audit Committee of the British Cardiac Society and a Cardiology Committee of Royal College of Physicians of London.

OBJECTIVE--To measure the delays between onset of symptoms and admission to hospital and provision of thrombolysis in patients with possible acute myocardial infarction. DESIGN--Observational study of patients admitted with suspected myocardial infarction during six months. SETTING--Six district general hospitals in Britain. SUBJECTS--1934 patients admitted with suspected myocardial infarction. MAIN OUTCOME MEASURES--Route of admission to hospital and time to admission and thrombolysis. RESULTS--Patients who made emergency calls did so sooner after onset of symptoms than those who called their doctor (median time 40 (95% confidence interval 30 to 52) minutes v 70 (60 to 90) minutes). General practitioners took a median of 20 (20 to 25) minutes to visit patients, rising to 30 (20 to 30) minutes during 0800-1200. The median time from call to arrival in hospital was 41 (38 to 47) minutes for patients who called an ambulance from home and 90 (90 to 94) minutes for those who contacted their doctor. The median time from arrival at hospital to thrombolysis was 80 (75 to 85) minutes for patients who were treated in the cardiac care unit and 31 (25 to 35) minutes for those treated in the accident and emergency department. CONCLUSION--The time from onset of symptoms to thrombolysis could be reduced substantially by more effective use of emergency services and faster provision of thrombolysis in accident and emergency departments.     

Deaths under 50. Medical Services Study Group of the Royal College of Physicians of London.

The Medical Services Study Group has started a collaborative study in the Mersey, West Midlands, and Grampian regions to examine the causes of death among medical inpatients aged 1 to 50. The cause of death is determined from the case notes and the consultant''s opinion. The rate of ascertainment of cases was initially low, though it is increasing; despite this limitation an analysis of the first 250 cases showed one important finding. No fewer than 98 patients contributed to their own deaths through overeating, drinking, smoking, or not complying with treatment. Despite the present statistical limitations of the study, it has been valuable in enlisting the good will of the participating physicians, which will help to ensure the success of other projects, and it has avoided the problems inherent in determining the cause of death from death certificates alone.     

Fecal Microbiota Transplantation via Colonoscopy for Recurrent C. difficile Infection

Fecal Microbiota Transplantation (FMT) is a safe and highly effective treatment for recurrent and refractory C. difficile infection (CDI). Various methods of FMT administration have been reported in the literature including nasogastric tube, upper endoscopy, enema and colonoscopy. FMT via colonoscopy yields excellent cure rates and is also well tolerated. We have found that patients find this an acceptable and tolerable mode of delivery. At our Center, we have initiated a fecal transplant program for patients with recurrent or refractory CDI. We have developed a protocol using an iterative process of revision and have performed 24 fecal transplants on 22 patients with success rates comparable to the current published literature. A systematic approach to patient and donor screening, preparation of stool, and delivery of the stool maximizes therapeutic success. Here we detail each step of the FMT protocol that can be carried out at any endoscopy center with a high degree of safety and success.     

Current X-ray diagnosis of stomach cancer (comparison of radiologic and morphological methods of investigation)

By using the principles of wide comparisons of the data of radiation diagnosis (routine X-ray study, ultrasonography (USG), CT, MRI) with the morphological findings of resected gastric specimens from patients with endophytic gastric cancer (EGC) (n = 85), the authors propose some points in the problem associated with its diagnosis. They believe that by taking into account the fact that there is an obvious growth of endophytic parietally growing gastric cancer with the concurrent reduction in its intestinal forms, it is necessary to restore current radiation to its leading place, along with endoscopy, in detecting the cancer. The authors makes a highly positive assessment of USG, CT, MRI in addition to routine X-ray study and endoscopy particularly in those cases when difficulties emerge in histological verification of the existing signs of parietally growing cancer. The paper makes indications for USG, CT, MRI concrete. The authors also show how to stage gastric cancer.     

Nonulcer dyspepsia.

One third to one half of cases of dyspepsia remain unexplained. The cause of nonulcer dyspepsia is unknown, but aerophagia, esophageal dysfunction, pyloroduodenal dysmotility and the irritable bowel syndrome may be important factors in some patients. The symptoms are often affected by diet and emotion. History-taking and endoscopy are the most discriminating diagnostic tests. Unexplained dyspepsia tends to be a lifelong disease with few, if any, sequelae. Nevertheless, reassurance and treatment with a placebo, such as an antacid or simethicone, provide effective and safe relief for many patients.     

Long-term Effects of Hydroxyurea in Psoriasis

Hydroxyurea is an effective treatment for psoriasis but consistently produces macrocytosis in peripheral blood with a fall in haemoglobin levels and white cell counts. In this long-term study of 16 patients anaemia and leukopenia have proved frequent and troublesome side effects requiring discontinuance of treatment in many cases. In view of these findings hydroxyurea cannot be recommended as the drug of first choice even for treating severe and intractable psoriasis, and it is our opinion that methotrexate is safer and at least as effective in these circumstances. The clearest indications for the use of hydroxyurea appear to be in life-ruining psoriasis when methotrexate treatment has either failed or is contraindicated because of liver damage. A great deal more investigative work is required before these indications can be generally extended.     

Response of patients to upper gastrointestinal endoscopy: effect of inherent personality traits and premedication with diazepam.

The influence of personality traits on the reaction of patients to upper gastrointestinal endoscopy was studied prospectively in 86 patients. High N (neuroticism) scores on the Eysenck personality inventory were associated with poor tolerance to and future compliance with the procedure. Although premedication with diazepam did not affect the degree of discomfort and distress during the procedure, it guaranteed acceptance of repeat endoscopy by virtue of its strong amnesic effect. By contrast, not giving premedication to patients who were anxious and had high N scores jeopardized future compliance. These findings suggest that a version of the Eysenck personality inventory should be used to assess patients'' neurotic phenotype and their need for premedication before endoscopy. Alternatively, all patients might be given premedication.     

Influence of the Royal College of Radiologists' guidelines on hospital practice: a multicentre study. Royal College of Radiologists Working Party.

OBJECTIVE--To measure the effect on hospital radiology referral practice of introducing a strategy for change involving guidelines of good practice, monitoring, and peer review. DESIGN--Prospective data collection over a continuous 21-24 month period at each centre some time between January 1987 and December 1990. SETTING--Five district general hospitals and one district health authority. SUBJECTS--314,663 inpatient discharges, deaths, and day cases and 1,706,781 outpatient attendances under the care of 722 consultants from 25 clinical specialties. MAIN OUTCOME MEASURES--Number of referrals for x ray examination per 100 inpatient discharges, deaths, and day cases and per 100 new outpatient attenders. RESULTS--Most doctors were prepared to accept standards of clinical practice set by peers and also the monitoring and review of their practice with respect to these standards by local colleagues. 18% of firms were identified before guidelines were instituted as having persistently high referral rates. Appreciable, and often dramatic reductions in referral rates for individual x ray examinations were recorded by a substantial number of firms in every centre and in every specialty after guidelines were instituted. The major part of this reduction was achieved by some of the firms whose initial practice did not meet "high referral" criteria. Important variations in compliance with agreed standards of good practice were observed. CONCLUSIONS--The study offers strong experimental evidence to support a recent suggestion that at least a fifth of radiological examinations carried out in NHS hospitals are clinically unhelpful. The problem of how to assure compliance with agreed standards of practice needs to be resolved. Until this happens medical audit alone is unlikely to translate good practice into common practice.     

Healing of gastric ulcers after one,two, and three months of ranitidine.

Ranitidine (150 mg twice daily) was compared with placebo in 42 patients with gastric ulcer. The study was conducted as a double-blind trial for one month, followed by an open assessment of one, two, and three months of ranitidine in the patients with persistent ulceration. Thirty-eight patients completed the double-blind trial. Repeat endoscopy confirmed complete healing in 16 of the 21 who had received ranitidine and five of the 17 who had received placebo (p less than 0.01). The remaining 17 patients with persistent ulceration participated in the open assessment. The combined cumulative healing rates of ranitidine at four, eight, and 12 weeks were 73%, 88%, and 97%. There were no adverse effects or unusual reasons for withdrawal from the study (four patients). Ranitidine appears to be a safe and highly effective treatment of gastric ulceration, with about 90% of ulcers healed after eight weeks.     

3-Year experience of use of cefepime (Maxipime) for the treatment of hospital infections in a specialized surgical hospital]

Microbiological and clinical monitoring for 3 years (from 2001 to 2003) confirmed high clinical and microbiological efficacy of cefepime (Maxipime, Bristol-Myers-Squibb) in the treatment of infectious complications in patients with solid tumors in an oncologic hospital. It should be noted, however, that high efficacy of cefepime and wide ranges of the indications to its use do not allow to consider it as an agent for the treatment of all possible complications in such patients. The drug is not active against enterococci, not always clinically sufficiently effective in the treatment of Pseudomonas aeruginosa infections, it is impossible to use cefepime in monotherapy of suspected anaerobic infections. Therefore, widespread uncontrolled use of cefepime should be prohibited. It should be prescribed strictly by the indications with the account of the pathogen susceptibility, the infection severity and the recommended doses and regimens. The use of cefepime is undoubtedly valid when other antimicrobials fail or when empirical antimicrobial therapy of severe cases is required, including those under intensive care.     

Is serum protein electrophoresis useful in separating the "high risk group" in patients with colonic polyps?

BACKGROUND: Adenomas have the highest potential or clinical value from among colonic polyps of developing into adenocarcinoma. The aims of this paper are: to establish criteria to identify the high risk group of patients in a group of patients with colonic polyps, to work out a simple scheme for follow-up care after endoscopic polypectomy, and to establish indications for surgery. The usefulness of determination of electrophoresis of serum proteins has been specially analysed to detect early development of malignant growths in patients with colonic polyps regarding alfa-1/alfa-2 and alfa/beta. 67 cases - 21 women, 46 men were tested. Follow-up endoscopy with the electrophoresis was performed after 6 weeks, 6 and 12 months after polypectomy. 97 polyps were resected with endoscopy in 67 patients. 38 patients (39.17%), those constituting the high risk group, were selected. Included were all polyps with grade II and III of cellular differentiation. CONCLUSIONS: 1) alfa-1/alfa-2 and alfa/beta is a helpful test in identifying the high risk group among patients with colonic polyps and it can be used as a screening test, 2) the determination of beta-2-macroglobuline is not useful in the diagnosis of this group of patients, 3) the electrophoresis of proteins should be the first test to perform on patients with colonic polyps. The relation of electrophoresis to endoscopic polypectomy aids evaluations of patients specially predisposed to malignant.     

Scoring system to improve cost effectiveness of open access endoscopy.

The introduction of an open access general practitioner endoscopy service may result in many unnecessary examinations being performed. In an attempt to prevent this, 235 patients attending for endoscopy were interviewed and the results analysed to determine which factors best discriminated between those with major disease (ulcers, cancers, oesophageal strictures; n = 48) and those without (n = 187). The six characteristics which best discriminated between the two groups were increasing age, history of vomiting, male sex, smoking, and a past history of peptic ulcer or hiatus hernia. With the use of these six features a scoring system was devised, designed to give an indication of the likelihood of finding such disease in an individual patient. This was assessed prospectively in a further 356 patients. The results showed that by utilising this scoring system it would be possible to reduce the number of examinations performed by 30% yet still detect 98% of serious disease. If confirmed in further prospective studies, this scoring system (or a modification) could more accurately assess individual priority for endoscopy and enable optimum use to be made of limited resources.     

Injection immunotherapy. British Society for Allergy and Clinical Immunology Working Party.

A working party of the British Society for Allergy and Clinical Immunology has reviewed the role of specific allergen immunotherapy in the treatment of allergic disease and produced a position statement summarising the available evidence for efficacy and safety. The working party recommends specific allergen immunotherapy for treating summer hay fever uncontrolled by conventional medication and for wasp and bee venom hypersensitivity. It is not recommended for asthma or for allergic rhinitis due to other allergens. For the recommended indications the risk:benefit ratio is acceptable provided patients are carefully selected; in particular, patients with asthma should be excluded as they are especially vulnerable to adverse reactions. Injections should be given only by doctors experiences in this form of treatment in a clinic where full resuscitative facilities are immediately available. Provided patients remain symptom free a 60 minute observation period after injection is sufficient to detect all serious adverse reactions.     

Management of variceal haemorrhage.

Fig 2 gives an algorithm for the treatment of bleeding oesophageal varices. Initial resuscitation of the patient is of paramount importance, ideally followed by early interventional endoscopy. Recent advances in available endoscopic techniques enable the endoscopist to suit the therapeutic approach to the clinical situation. Injection sclerotherapy remains the initial treatment of choice in bleeding patients. Endoscopic banding ligation is an alternative, best used in patients who have spontaneously stopped bleeding or as a complementary treatment a few days after the initial session of injection sclerotherapy. The tissue adhesives and thrombin can be used to treat bleeding gastric varices. [table: see text] Should the endoscopic expertise not be available, drug treatment (with somatostatin or octreotide) or balloon tamponade are the treatments of choice. Transjugular intrahepatic portal-systemic stent shunt is a new effective technique, not yet widely available, which has a documented complication rate that has yet to be fully defined. It is a good alternative to surgery as a "rescue" procedure for patients who continue to bleed despite two sessions of endoscopic intervention.     

Ocular fundus abnormalities detected by fluorescein and indocyanine green angiography in the Royal College of Surgeons dystrophic rat.

The ocular fundi of the Royal College of Surgeons (RCS) dystrophic rats were examined by conventional fundus photography, fluorescein angiography (FA) and indocyanine green angiography (IA). In the fundus, a reddish colored background was observed in the RCS dystrophic rats at 3 weeks of age. At 9 weeks of age, the background had changed to pale in color. In FA, the RCS dystrophic rats at 3 week of age demonstrated background fluorescence with homogeneous brightness. Fluorescent dye leakage was observed in the late phase of the postinjection period at 9 weeks of age. In IA, the RCS dystrophic rats at 3 weeks of age had background fluorescence with homogeneous brightness, and at 5 weeks of age, spots of hyperfluorescence were scattered over the dark background. At 7 weeks of age, numerous delimited, irregular round spots of hyperfluorescence appeared over the dark background. Such hyperfluorescent lesions had further increased in number and size in the RCS dystrophic rats at 9 weeks of age. In this way, ocular findings related to abnormalities in the retinal pigment epithelium and choroid in the RCS dystrophic rat were demonstrated by fundus photography, fluorescein angiography and indocyanine green angiography.     

Upper gastrointestinal endoscopy: its effects on patient management.

Out of 95 patients referred for upper gastrointestinal endoscopy after a barium-meal examination, 44 underwent a change in management. Some changes were minor but in 12 patients a decision on surgery was required. Seven of these patients were among a group of 13 for whom the referring consultant would have recommended laparotomy had endoscopy not been available, while the other five were subjected to an unplanned laparotomy. These findings support the practice of performing endoscopy on patients whose symptoms are not fully explained by barium-meal examination, especially patients aged over 45. In such cases the procedure also seems to be cost-effective.
