Impact of alcohol related disease and inpatient workload of gastroenterologists in Scotland.

BACKGROUND: Concern among Scots gastroenterologists about alcohol related illness prompted this inpatient prevalence study during the winter of 2000-01. AIMS: To study gastrenterology inpatient workload due to alcohol-related illness, to determine how much was specialty specific, and if there were regional variations. METHODS: 40 Consultant gastrenterologists throughout Scotland collected data on the prevalence of alcohol related conditions among inpatients under their care on each of three specified days during the winter of 2000/2001. All inpatients under the care of participating consultants on the designated study days were included in the study. Overall return rate was 65%. Patients were categorised as follows; (a) general medical inpatients admitted for reasons other than alcohol related illness (b) general medical inpatients with no gastrointestinal or liver disease, but whose admission to hospital was primarily related to alcohol misuse, (c) gastrointestinal (including liver) inpatients admitted for reasons unrelated to alcohol intake, and with no alcohol related disease, and (d) gastrointestinal inpatients whose admission to hospital resulted from alcohol related disease. Additionally the numbers of patients with (e) decompensated liver disease of all causes, (f) decompensated alcoholic liver disease, and (g) the numbers "blocking" acute beds after initial hospitalisation with an alcohol related illness were collected. RESULTS: Overall, 829 general medical and 538 gastroenterology inpatients were entered in the study; total 1367 (705 male, 662 female). Of these, 25% (337/1367) were admitted because of alcohol related illness: 15% (201/1367) had decompensated alcoholic liver disease. Of 538 gastroenterology inpatients, 238 (44%) had problems related to alcohol and 201 of these (37% of all gastoenterology inpatients) had decompensated alcoholic liver disease. Of 246 inpatients with decompensated liver disease, 82% (201) had alcoholic liver disease. Alcohol related illness was significantly more prevalent among male inpatients in the West of Scotland. 10% of specialist gastroentelogy beds were occupied by patients whose discharge was delayed because of alcohol related problems. CONCLUSION: Most Scottish gastroenterlogists contribute to general medical receiving but their specialist inpatient workload is dominated by treatment of patients with alcohol related disease. (44% in gastroenterology v 12% in general medicine). Inpatients with decompensated alcoholic liver disease form 37% of gastroenterology workload. Alcohol related disease contributes to delayed discharge in acute medical units, especially in gastroenterology wards. There are regional differences in prevalence of alcohol related disease, which is greatest in male inpatients in the West of Scotland. Here, alcoholic liver disease accounts for nearly a decompensated liver disease. The findings point to a need to review the current patterns of acute service provision for alcohol related illnesses, so as to assess and improve both the linical effectiveness and cost effectiveness of care, and to ensure that alternatives to acute hospital admission are available when appropriate. This need should not be neglected while efforts are simultaneously being made to improve the early detection of alcohol abuse and prevent irreversible alcohol related disease.

Analysis of alcohol-related admissions in gastroenterology, cardiology and respiratory medicine.

A 4 week study of medical inpatients was performed to look at prevalence of alcohol-related problems in three different sub-specialties. Alcohol-related conditions accounted for 51% of gastroenterology inpatients, and 65% of these patients had alcoholic liver disease. In contrast, the cardiologists and respiratory physicians managed for less alcohol-related pathology, accounting for only 6% of inpatients in each specialty. Alcohol-related conditions were three times commoner in men. Patients admitted due to alcohol had longer lengths of stay, and experienced higher morbidity and mortality. These findings have important implications for health care planning and provision. They highlight a need for specialist training to be given to staff who deal with alcohol-related conditions on a daily basis. There is also a significant public health issue raised by these results regarding public attitudes in Scotland towards alcohol abuse and the increasing burden it is placing on the NHS.

Open reduction and internal fixation of fractured mandibular condyles by a retromandibular approach: surgical morbidity and informed consent.

Treatment of fractured mandibular condyles remains controversial. In this paper we present data collected prospectively on 42 fractured condyles treated by open reduction and internal fixation. The central issue, which is sometimes forgotten, is the informed consent of our patients. To this end we have looked at the surgical morbidity related to the retromandibular approach.

Consultants workload due to alcohol related conditions in acute medical receiving gastroenterology and endocrinology.

A four-week survey was performed into the incidence of alcohol related problems in the acute medical receiving unit, and the prevalence of alcohol related cases in a ward shared between two gastroenterologists and an endocrinologist. Alcohol related conditions were the commonest reason for acute admission (19%). Gastroenterologists, in contrast to their colleagues have a substantial workload related to alcohol, especially chronic liver disease. These patients have longer lengths of stay with higher morbidity and mortality than those without alcohol related conditions. The reason for these differences and the implications for service planning are discussed.

Transient hemi-diaphragmatic paralysis following neck surgery: report of a case and review of the literature.

Diaphragmatic paresis following trauma to the phrenic nerves is a rare complication after neck surgery. The resulting elevation of the ipsilateral hemi-diaphragm is diagnosed on post-operative chest radiography and may be confirmed by ultrasound or fluoroscopy. When unilateral, this may lead to respiratory, cardiac or gastrointestinal symptoms and atelectasis and pulmonary infiltrates on radiography. If nerve damage is bilateral a period of ventilation may be required.

Mass carbon monoxide poisoning.

The largest occurrence of carbon monoxide poisoning in Britain demonstrates the potential for mass accidental poisoning. It emphasises the need for strict public health controls and the importance of good liaison between emergency services to ensure that such events are quickly recognised and that the necessary resources are organised.

A grading system in day surgery: effective utilization of theatre time.

An in-house audit revealed a theatre utilization time in the day surgery unit of 70%. The reason identified for this poor theatre utilization was patient selection by the clerical staff based on a fixed number of cases per session. A grading system which estimated the anticipated duration of operation time was introduced as the basis for patient selection in the day surgery. A pilot study of 20 patients revealed that the system was both effective and simple to implement. It was therefore adopted. A re-audit of a further 299 patients treated using the grading system revealed that theatre utilization time had increased from 70 to 98%. The number of patients treated per session also increased, thus effectively reducing the waiting list. The grading system can be used in all clinical specialities providing day case surgery and we recommend it.

Treatment of retrobulbar haemorrhage in accident and emergency departments.

Retrobulbar haemorrhage is a rare complication of orbital injury or surgery. After injury the first clinicians to see these patients are often the staff of accident and emergency departments. This survey was instigated after several patients had been referred to our care irreversibly blind. A multiple choice questionnaire was devised and sent to 90 doctors working in accident and emergency departments in Scotland. A total of 57 (63%) were returned of which 55 were complete enough to analyse. The range of respondents was: consultants (n = 6), associate specialists (n = 3), senior registrars (n = 3), registrars (n = 4), senior house officer (n = 35), and clinical assistants (n = 4). Twenty nine of the 35 senior house officers (83%) were unable to diagnose and treat retrobulbar haemorrhage. Most consultants, senior registrars, registrars and associate specialists were significantly better in the diagnosis and treatment of this condition (P = 0.001). We conclude that there is an unacceptably high incidence of blindness as a result of inappropriate diagnosis and treatment of retrobulbar haemorrhage. We have therefore designed a protocol for accident departments which should help reduce the incidence of blindness.

A comparison of omeprazole and ranitidine in the prevention of recurrence of benign esophageal stricture. Restore Investigator Group.

BACKGROUND/AIMS: Dilatation combined with subsequent pharmacological control of gastroesophageal reflux represents a logical but poorly documented approach to the management of benign esophageal stricture. This large trial (366 patients) aimed to assess whether omeprazole as the most effective available medication for gastroesophageal reflux disease prevents recurrent stricture formation. METHODS: Patients (n = 366) were randomized in a double-blind study to undergo either omeprazole (20 mg once daily; 180 evaluable patients) or ranitidine therapy (150 mg twice daily; 185 evaluable patients) for 1 year after dilatation to 12-18-mm diameter (36-54F gauge). Subsequently, endoscopy and dilatation were performed when clinically indicated and endoscopy on completion. Symptoms were assessed at clinic visits every 3 months and using weekly diary cards. RESULTS: Fewer patients undergoing omeprazole therapy required redilatation compared with those on ranitidine (43 of 143 [30%] vs. 66 of 143 [46%] by 12 months; P < 0.01), and patients in the omeprazole group needed fewer redilatations during the year (0.48 vs. 1.08; P < 0.01). On completion, symptom relief favored omeprazole: 76% of patients in the omeprazole group were free of dysphagia (compared with 64% in the ranitidine group; P < 0.05); 83% were able to accept a normal diet (69%; P < 0.01); and 65% were completely asymptomatic (43%; P < 0.001). CONCLUSIONS: Omeprazole, 20 mg once daily, was more effective than ranitidine, 150 mg twice daily, as prophylaxis against stricture recurrence and in providing symptom relief.

Retrobulbar haemorrhage: can blindness be prevented?

Retrobulbar haemorrhage is a rare complication following orbital trauma or surgery occurring in less than 1 per cent of cases. Early diagnosis and treatment of this complication may save the vision of the affected eye. This paper illustrates cases where diagnosis was not made and blindness resulted. We also present two cases of successful treatment due to early diagnosis.

Effect of propranolol on prevention of first variceal bleed and survival in patients with chronic liver disease.

BACKGROUND: Propranolol has been shown to be effective in both primary and secondary treatment of variceal haemorrhage; most primary prevention trials have only included patients with large oesophageal varices. AIM OF THE STUDY: The aim of this study was to look at the effect of propranolol in the primary prevention of variceal bleeding and its long-term effects on mortality in unselected patients with chronic liver disease. METHODOLOGY: Three hundred and nineteen patients were included in a double-blind parallel group study in three centres to receive propranolol 160 mg long-acting (LA) or placebo. Patients were followed up for a minimum of one year. RESULTS: There were eleven episodes of variceal bleeding and 38 deaths with no statistically significant difference in bleeding rates between the two treatment groups. Child's group and history of ascites were the most important prognostic factors determining the likelihood of early death and variceal bleeding respectively. CONCLUSIONS: In this study we failed to demonstrate a significant effect of propranolol on first variceal bleeding or in prolonging survival in unselected patients with chronic liver disease. Our results, however, might have been influenced by the low event rate observed in these unselected group of patients and suggest that careful selection of patients who are most likely to benefit from propranolol is important.

Rapid healing of gastric ulcers with lansoprazole.

BACKGROUND: Lansoprazole is a new proton pump inhibitor which powerfully decreases acid secretion. METHODS: We compared the efficacy and short-term safety of lansoprazole against ranitidine in the healing of gastric ulcer. This was a parallel group, comparative multicentre, prospectively randomized, double-blind study which included 250 patients with gastric ulcer, 219 of whom had follow-up endoscopic data. RESULTS: Both lansoprazole 30 mg and 60 mg daily produced significantly more rapid healing of gastric ulcer than ranitidine 300 mg nightly with healing rates after 4 weeks of 78% (P < 0.05), 84% (P < 0.01) and 61%, respectively. After 8 weeks, the corresponding healing rates were 99%, 97% and 91% (P = 0.08). Symptom relief was similar for all treatment groups, but fewer antacids were used by patients receiving lansoprazole. Sixty-nine patients experienced 91 adverse events; the incidence, pattern and severity was similar across all three treatment groups. CONCLUSIONS: Lansoprazole 30 mg and 60 mg once daily had similar efficacy. Both were superior to ranitidine 300 mg nocte in healing gastric ulcer. The short-term safety profile of lansoprazole was similar to ranitidine. These data indicate that lansoprazole should be used at a dose of 30 mg once daily for the treatment of gastric ulcers.

Ovine chlamydiosis in an abattoir worker.

The strain of Chlamydia psittaci causing enzootic abortion in ewes (the EAE strain) may cause serious infection in pregnant women, often resulting in hepatic and renal dysfunction, disseminated intravascular coagulation and fetal loss. The first case of such an infection in an abattoir worker is described and the possibility of human-to-human transmission considered. Direct handling of sheep or their products of conception can usually be established but this is not always so. There is much still to be learned about this uncommon but severe zoonosis.

Abnormal bone masses in Klippel-Feil syndrome.

Five female patients with Klippel-Feil syndrome (KFS) are presented with abnormal bony masses in the mandibular ramus region. The features of KFS are described with assessment and treatment of the five patients. Although congenital duplication of mandibular rami in KFS has been previously documented, we believe this is the first series of patients with this deformity.

A prospective study of alcoholic liver disease and mortality.

We report the 10-year survival of 510 patients with a histological diagnosis of alcoholic liver disease. Eight centres in Scotland and North England contributed to this study. Information was available on 92% of the initial cohort. Age was important, with each decade increasing mortality by 55%. A highly significant interaction between sex and histology was observed with a marked survival benefit for males with non-cirrhotic alcoholic liver disease, while in cirrhotic subjects the pattern was reversed. Patients with decompensated liver disease had a relative increase in mortality in excess of 86% while the increase in mortality for alcoholic hepatitis, 'active' cirrhosis and 'inactive' cirrhosis were 52%, 57% and 91% relative to fatty liver. Alcohol intake at the time of diagnosis did not influence outcome. This study emphasises yet again the increased mortality rate of individuals abusing alcohol compared with the general population.

A modified surgical approach for parapharyngeal space tumours: use of the inverted 'L' osteotomy.

Removal of tumours from the parapharyngeal space is often difficult because of limited surgical access. Mandibulotomy has proved useful for improving access but may cause damage to the inferior dental and lingual nerves. Use of the inverted 'L' osteotomy provides excellent access avoiding damage to the nerves and the technique is illustrated with three surgical cases.
