Hilton's Rest and Pain, Guy's Hospital personalities and Guy's South African rugby connection.
Guy's Hospital occupies a unique position in medical history. John Hilton (1805-1879), as anatomist, physiologist, morbid anatomist and surgeon in his classic Rest and Pain, published in 1863 (reissued in 1950), formulated principles for the diagnostic significance of pain and the value of rest in healing. An array of personalities graced Guy's Medical School in that era. The triumvirate of Richard Bright (1789-1858). Thomas Addison (1793-1860) and Thomas Hodgkin (1798-1866) contemporaneously discovered the diseases that bear their names. Sir Astley Cooper, a leading surgeon of his day (1768-1841), performed the first amputation of the hip joint before the era of anaesthesia. John Keats (1795-1821) qualified as a surgeon at Guy's but, realising his unsuitability of temperament, became a leading English poet. This change of direction caused him anguish and suffering, mainly because of the rejection of his poetry; tuberculosis led to his death in Rome, where he is buried. Guy's Medical School also allowed South Africans to enter as rugby players before the 1920s, when they were required to qualify overseas.

Hospital-sponsored health plans battle the big guys.
Hospitals are developing their own healthcare networks and managed-care plans to take on the industry's giants. And, against seemingly long odds, they're finding some success as they see increases in the medical services performed at their facilities and capture bigger pieces of market share. Executives say the local plans have a cost advantage, enabling them to develop more competitive packages.

Clinical diagnosis of intracranial haemorrhage using Guy's Hospital score.
We tested the Guy's Hospital stroke diagnostic score using the clinical data from two independent samples of patients with acute stroke. These were 228 patients from the Oxfordshire community stroke project and 130 referred to the National Hospital for Nervous Diseases in London. The diagnosis was confirmed by computed tomography or necropsy in each case. The optimum cut off point on the clinical score for the differentiation of intracranial haemorrhage from infarction was found to be the same for both the patients in our study and those from whose data the score was derived originally. Set at this level, the score achieved a sensitivity for the diagnosis of haemorrhage of 81% and 88% in the patients from Oxford and London, respectively. In those from Oxford infarction was diagnosed with a sensitivity of 78% with an overall predictive accuracy of 78% with an overall London the sensitivity for infarction was also 78% with an overall predictive accuracy of 82%. When it is essential to exclude intracerebral blood before starting treatment in the small proportion of patients with stroke who require anticoagulation the Guy's Hospital score is not sufficiently accurate to replace computed tomography. The score is, however, the most accurate clinical means of differentiating haemorrhage from infarction as the cause of stroke. It is suggested that it should be used as a screening test in epidemiological studies and in large scale trials of low risk treatment for the secondary prevention of stroke when computed tomography in all cases is impracticable.

Poor accuracy of the Siriraj and Guy's hospital stroke scores in distinguishing haemorrhagic from ischaemic stroke in a rural, tertiary care hospital.
BACKGROUND: In India stroke is associated with a high morbidity and mortality. Bedside clinical examination does not always help in distinguishing cerebral infarction from intracranial haemorrhage. We evaluated the accuracy of the Guy's hospital and Siriraj stroke scores in distinguishing haemorrhagic from ischaemic stroke in a rural setting. METHODS: Patients with suspected stroke admitted to a rural teaching hospital were prospectively enrolled. Two investigators collected data for computing the Guy's hospital and Siriraj scores. Cut-off points, as described by the authors of the original scores, were used to predict haemorrhage and infarction. The scores were compared in a blind and independent manner with the computed tomography (CT) scan. The sensitivity, specificity, positive and negative likelihood ratios and agreement between the two scores were calculated. RESULTS: Of the 259 patients admitted for suspected stroke, 134 patients (73 men) underwent both clinical evaluation and a CT scan. The Siriraj score discriminated haemorrhage from infarction with a sensitivity of 78.5% (95% CI: 66.5, 87.7) and specificity of 71% (95% CI: 52, 85.8). The likelihood ratio of a positive test was 2.7 (95% CI: 1.54, 4.75) and that of a negative test was 0.3 (95% CI: 0.17, 0.53). For the Guy's hospital score the sensitivity was 81% (95% CI: 68.6, 90.1), specificity 76.2% (95% CI: 52.8, 91.8), likelihood ratio of a positive test 3.4 (95% CI: 1.57, 7.39) and that of a negative test 0.25 (95% CI: 0.11, 0.54). Both scores, when combined, were 80% sensitive (95% CI: 66.3, 90) and 80% specific (95% CI: 51.9, 95.7). The agreement between the two scores was modest (kappa = 0.51), but very good (kappa = 0.93) after exclusion of equivocal score results. CONCLUSION: Our study suggests that neither of the stroke scores is sufficiently accurate for distinguishing the type of stroke. CT scan, and not history and clinical signs, can accurately identify haemorrhage from infarction in acute stroke.

The pulmonary autograft--a permanent aortic valve.
Between 1969 and 1991, 339 patients had an aortic valve replacement with their own living pulmonary valve at the National Heart Hospital, Guy's Hospital and the Harley Street Clinic, London. The longest follow-up is 24 years and cumulative follow-up is 3774 patient-years. No form of anticoagulation was used and there were no emboli. There were 25 hospital deaths (7.4%) but only 1 death since 1976. Late deaths occurred in 38 patients mainly from technical mal-insertion. Bacterial endocarditis occurred in 11 patients. Thirty-eight patients were re-operated upon and account for 15 of the late deaths. Freedom from re-operation was 85% and the actuarial patient survival was 80% at 20 years. There has been no evidence of primary tissue degeneration and explanted valves showed normal cusp cellularity. Accumulating evidence suggests that the cusps not only survive permanently but can grow with the patient making the operation ideal for children.

Frederick Akbar Mahomed.
Frederick Akbar Mahomed was an Englishman of mixed Indian and Irish descent who made substantial contributions to the study of high blood pressure in a short professional life from 1872 to 1884. He was strongly influenced by the previous work of Richard Bright on kidney disease at his own hospital (Guy's Hospital in London) and by the contemporary pathological studies of Gull and Sutton on arteriolar changes in persons with high blood pressure. In detailed clinical studies, he separated chronic nephritis with secondary hypertension from what we now term essential hypertension. He described the constitutional basis and natural history of essential hypertension and pointed out that this disease could terminate with nephrosclerosis and renal failure. His clinical studies were done without the benefit of a sphygmomanometer but with the aid of a quantitative sphygmogram that he had initially developed while a medical student. He described characteristic features of the pressure pulse in patients with high blood pressure and in persons with arteriosclerosis consequent on aging. These pressure wave changes have recently been verified and explained. He contributed to a number of other advances in medical care, including blood transfusion and appendectomy for appendicitis. He initiated the Collective Investigation Record for the British Medical Association; this organization collected data from physicians practicing outside the hospital setting and was the precursor of modern collaborative clinical trials. Mahomed died from typhoid fever, almost certainly contracted from one of his patients, at age 35 at the height of his career.

Two decades' experience with aortic valve replacement with pulmonary autograft.
Aortic valve replacement with a pulmonary autograft was performed on 241 patients between June 1967 and October 1986 at National Heart Hospital, Guy's Hospital, Middlesex Hospital, Harley Street Clinic, and Italian Hospital in London by one of the authors (D.N.R.). The longest follow-up is 18 years 7 months, and the cumulative total follow-up is 1130 patient-years (pt-yr). The overall 30-day mortality rate is 6.6% (16 patients), with no deaths after 1976, and the late mortality rate is 1.7%/pt-yr (19 patients). The actuarial survival rate is 57.3% +/- 9.6% at 19 years. No anticoagulation has been used and there have been no thromboembolic episodes. The incidence of bacterial endocarditis is 1.2%/pt-yr (14 patients), and its actuarial event-free rate is 74.2% +/- 8.1% at 19 years. Reoperation because of failure of the pulmonary autograft was performed on 36 patients, 27 of whom needed valve replacement. The incidence of pulmonary autograft replacement is 2.5%/pt-yr, and its actuarial event-free rate is 48.5% +/- 13.7% at 19 years. For reconstruction of the right ventricular outflow tract, 186 aortic homografts, 26 pulmonary homografts, 16 autologous fascia lata valved conduits, 7 autologous pericardial conduits with or without a valve, and 6 xenograft valved Dacron conduits were used. Thirty-one patients were reoperated on, mostly because of degeneration of this material. Pulmonary rather than aortic homografts are now favored for reconstruction of the right ventricular outflow tract Because of its satisfactory long-term result without the need for anticoagulation, as well as its safety as an established surgical procedure, this operation can be recommended to a wider range of patients.

Accuracy of the Siriraj and Guy's Hospital Stroke Scores in urban South Africans.
BACKGROUND AND PURPOSE: The burden of stroke in sub-Saharan Africa is already high and likely to increase, but few patients with stroke have access to brain imaging. Distinguishing pathologic stroke types is relevant both for clinical management and epidemiologic studies. We assessed the accuracy of two stroke scores in distinguishing stroke types in a population known to have a high prevalence of intracranial hemorrhage but low prevalence of atherosclerosis and compared them with the clinicians' assessment of stroke type with computed tomography brain scanning as the "gold standard." METHODS: We assessed the stroke scores and the clinicians' blind assessment of pathologic stroke type in consecutive black patients with stroke included in the Johannesburg Hospital Stroke Register over 23 months. We calculated the accuracy of the scores and clinicians compared with computed tomography brain scan (sensitivity, specificity, positive predictive value, likelihood ratio, kappa statistic). RESULTS: Two hundred twenty-two patients were scanned and assessed within 15 days. Sixty-two (28%) had cerebral hemorrhage and nine (4%) subarachnoid hemorrhage. Neither the Siriraj (sub-Saharan Africa) nor Guy's Hospital score was accurate or offered much advantage over clinician assessment (sensitivity 0.60 and 0.34, specificity 0.88 and 0.95 for intracranial hemorrhage in the Siriraj Stroke Score and Guy's Hospital Stroke Score, respectively; sensitivity 0.70 and 0.71, specificity 0.84 and 0.74, respectively, for ischemic stroke). Although the scores were more accurate when we used new cutoff points, they then failed to diagnose over 80% of stroke types. CONCLUSIONS: The Siriraj Stroke Score and Guy's Hospital Stroke Score are not sufficiently accurate for use in either epidemiologic studies or to guide clinical management in sub-Saharan Africa at present.

The impact of the observation ward on acute admissions at Guy's Hospital.
This paper describes an evaluation of the short-stay ward at Guy's Hospital Accident and Emergency Department. It includes an audit of the operational policy, the care provided to patients, and the impact of the short-stay ward on hospital admissions. The results indicate that by concentrating patients in a short-stay ward, the quality of care is improved, delays are reduced, and the pressure on inpatient beds is relieved.

[Guy's Hospital home dialysis program (author's transl)].
The first home dialysis was carried out from Guy's Hospital in London in 1968. Since then, 141 patients have been treated in this manner. The age of the patients ranged from 4 to 64 years. 24 patients have died (cerebrovascular accidents, myocardial infarction, pulmonary edema, sepsis, peritonitis, hyperkalemia etc.). Some of the deaths were due to a slackening of discipline on the part of the patients and nursing staff during the years of constant dialysis. Of 60 adults 52 were able to start work again; full rehabilitation still seems possible in 6 cases. Nevertheless, many patients cannot lead a normal life because their social and sexual activity is greatly restricted. The present economic crisis led to financial limitations in the National Health Service. In future, home dialysis may have to be reduced and more transplantations performed.

Comparison of Siriraj and Guy's Hospital score to differentiate supratentorial ischaemic and haemorrhagic strokes in the Indian population.
In India, 70% of the population does not have access to computerised brain scanning. Siriraj score is a safe and reliable clinical method to asses acute stroke syndrome. 160 patients with acute stroke were analysed by Siriraj and Guy's hospital stroke score simultaneously. CT Scan was performed in all and subarachnoid haemorrhage was excluded. Ninety two patients (57.5%) had infarction and 68 (42.5%) had haemorrhage. Siriraj score formula revealed haemorrhage in 53 (80%) and infarction in 78 (83%), while in the rest the results were equivocal or incorrect. Guy's hospital score revealed haemorrhage in 45 (66%) and infarction in 59 (69%). Clinical features are also helpful in differentiating infarction from haemorrhage, but the accuracy is not as high as with Siriraj score and secondly Siriraj score is a very simple formula in comparison to Guy's score.

Acute chlormethiazole poisoning in patients notified to the Poisons Unit, Guy's Hospital, 1978--1981.
1 Out of 493 patients with suspected acute chlormethiazole poisoning notified to the Poisons Unit, Guy's Hospital during 1978--1981, the diagnosis was confirmed either analytically or by detailed clinical information in 108 patients, 40 of whom had ingested chlormethiazole alone. 2 The principal signs reported indicate that the clinical features of acute chlormethiazole poisoning resemble those of barbiturate poisoning, with deep coma (n = 66), respiratory depression (n = 26) and hypotension (n = 17) in the severe cases. Five patients died as a result of early, profound respiratory depression. 3 In 53 survivors in whom toxicological analyses were performed, poisoning with chlormethiazole alone had a better prognosis than when ethanol or other drugs were also present, except in patients with hepatic or pulmonary disease or in the elderly. 4 These results emphasise that although patients poisoned with chlormethiazole who survive to reach hospital generally have a good prognosis, fatal respiratory complications often occur before the patient can be treated.

Quality assurance in Guy's Hospital accident and emergency department.
This paper describes the development of a comprehensive, practical audit by the medical staff at the Accident and Emergency Department at Guy's Hospital. The audit has enabled a comprehensive systematic review of clinical care and its documentation. The results shows that audit of Accident Emergency medicine is possible when channelled by proforma. Junior doctors in this specialty exercise great autonomy, and the audit highlights their need for proper training and guidance from senior medical staff in the review of major and minor cases.

Inadequacy of clinical scoring systems to differentiate stroke subtypes in population-based studies.
BACKGROUND AND PURPOSE: We undertook to examine the usefulness for epidemiological studies of two well-known validated clinical scoring methods, the Guys' Hospital Stroke score and the Siriraj Hospital Stroke score, to classify strokes into the two main types, hemorrhagic and ischemic, in epidemiological studies. METHODS: Patients from a population-based stroke register who received either a CT scan or an autopsy were retrospectively scored using the two clinical scoring methods. The scores were then compared with the CT scan and autopsy results to determine the sensitivity, specificity, and positive predictive value for intracranial hemorrhage (primary intracerebral and subarachnoid hemorrhage) and ischemic stroke. RESULTS: Over a 12-month period, 554 patients from a population-based study underwent CT scanning. Films or autopsy reports were available for 521 patients, and of these, sufficient clinical information to calculate the Guys' Hospital Stroke score and the Siriraj Hospital Stroke score was available for 464 and 475 patients, respectively. For the Guys' Hospital Stroke score, the sensitivity and specificity for intracranial hemorrhage were 31% and 95%, respectively; the positive predictive value was 73%. The sensitivity and specificity for ischemic stroke were 78% and 70%, respectively, and the positive predictive value was 86%. For the Siriraj Hospital Stroke score, the sensitivity and the specificity for intracranial hemorrhage were 48% and 85%, respectively; the positive predictive value was 59%. The sensitivity and specificity for ischemic stroke were 61% and 74%, respectively, and the positive predictive value was 84%. CONCLUSIONS: This validation study suggests that both clinical scores lack sufficient validity to be used in epidemiological studies for classification of stroke types and should probably not be used in the randomization of patients into treatment trials using thrombolytic or antithrombotic drugs in the absence of diagnostic information based on neuroimaging techniques.
