Over the last ten years the efficacy of lithium salts in cluster headache has been well demonstrated. Our patient, who had been suffering from cluster headache for approximately 30 years, had been in haemodialysis treatment for the last ten years for chronic renal failure. Moreover, he was affected by heart failure and peptic ulcer. The patient was currently under therapy with Digitalis, Isorbide dinitrate, and ranitidine and was dialyzed three times a week for a total of five hours each time. Neither prophylactic headache therapy nor high doses of analgesic drugs had proved effective. Although this patient was in haemodialysis, lithium treatment was indicated. The administration of lithium carbonate 300 mg during dialysis days and 150 mg during non-dialysis days improved the attacks. Complete recovery from the attacks was obtained when the serum levels of lithium reached the therapeutic range. No side effects were noted.

Benign liver tumors are relatively uncommon and, even when large enough to be symptomatic, they usually remain undiagnosed prior to exploratory laparotomy. Hemangiomas constitute the majority of benign hepatic neoplasms and are 9 times as frequent in females as in males. Most are asymptomatic but abdominal swelling, a mass, or symptoms due to compression of adjacent organs may occur and abdominal hemorrhage is reported in 4.5% of patients. Hepatic hemangioma may produce a large arteriovenous communication serious enough to cause heart failure. Recently an increased frequency of liver tumors, mostly adenomas, has been noted in women taking oral contraceptives (OCs); the cause has been attributed to estrogens. The exact incidence is unknown but believed to be low. It is most common in women in their late 20s who have been on OCs for 7 years or more. The tumor occasionally completely regresses on withdrawal of the OCs. The tumor may be discovered incidentally at laparotomy or may manifest inself by pain, a palpable mass, or catastrophic hemoperitoneum. Hepatic adenoma is usually a solitary lesion and infrequently degenerates into malignancy. Differential diagnosis includes chronic gall bladder disease and peptic ulcer. Focal nodular hyperplasia (FNH) is apparently much less frequently related to OC use and is less likely to bleed seriously than adenoma. Hepatic chemistry is usually normal in adenoma and FNH, but slight increases in serum bilirubin, serum alkaline phosphatase, and serum transaminase may occur. Primary liver cancer (hepatocellular carcinoma or hepatoma) is mostly a disease of males and in the US and Western Europe seldom develops before age 40. Fibrolamellar carcinoma, which characteristically develops in adolescents and young adults, occurs with equal sex incidence. Doubt has been expressed about its relationship to OCs. In the US about 75% of primary hepatocellular carcinomas are associated with cirrhosis, and about 5% of cirrhosis cases develop primary liver cancer. Clinical manifestations of hepatoma have been divided into 5 groups: frank cancer (62.7%), acute abdominal cancer (8%), febrile cancer (8%), occult cancer (16%), and metastatic cancer (5%). Detection of large amounts of alpha fetoprotein has proven useful in diagnosis of hepatocellular carcinoma, but values may be negative in OC users. It has been estimated that 1/3 to 1/2 of all malignant tumors eventually metastasize to the liver.

The effect of chronic illness on the subjective quality of sleep, and the use of hypnotics was studied in a stratified random sample of elderly people. Six hundred subjects aged 65 years or over were included in the study. A structured interview on the quality of sleep and medical history was carried out. In addition, the majority of diagnoses were confirmed from the national health insurance documents of the subjects. Logistic regression analysis disclosed that only perceived poor health and peptic ulcer or esophagitis were associated with perceived poor sleep. Age did not contribute to the quality of sleep. Age over 80 years and the presence of peptic ulcer or esophagitis, heart failure, cholelithiasis, and, in particular, depression were associated with the habitual use of hypnotics. The results stress the importance of perceived poor general health status, and acid-related gastrointestinal diseases as the determinants of subjective poor sleep, rather than age or many specific somatic diseases as such. On the other hand, depression is a major determinant for the habitual use of hypnotics.

In the Netherlands the general practitioner (GP) plays an important role in prevention. Every Dutch citizen has to be registered with one GP and GPs know their patients well. Face-to-face contact is a relatively effective means of influencing behavior; if preventive advice is related to a patient's state of health, compliance may be stimulated. However, Dutch GPs have shown reluctance toward preventive work. Curing rather than preventing disease is emphasized in medical school. Many GPs doubt that they are entitled to interfere with a patients' lifestyle unless asked. Some GPs are aware of their limited knowledge of nutrition. Preventive work requires some reorganization of medical practice and can lead to an increased workload, without financial compensation. Then there is the "prevention paradox": preventive actions that have a demonstrable effect on the whole population bring only small benefits for individuals. Since 1989 the Dutch College of General Practitioners has published 60 standards for general practice. Several of these include advice on lifestyle and diet, eg, for non-insulin-dependent diabetes mellitus, hypertension, hypercholesterolemia, peptic ulcer, and heart failure. Prevention work in general practice must use only interventions proved to be effective and they must be feasible in the context of general practice. A trial collaboration of 118 GPs and 5 public health authorities between 1988 and 1990 for screening and lifestyle management of hypertension was a limited success. It brought to light the practical problems of this type of work in general practice. Present government priorities for GP-public health collaboration are influenza vaccination and cervical screening.

Recent reports commissioned by the Australian Government have highlighted the need to improve medication use in both community and hospital settings. Nurses are placed ideally to promote safe and effective drug use. The aim of this project was to develop and evaluate a computer-assisted instruction package, to help undergraduate nursing students improve their knowledge of clinical pharmacology, and to enhance their ability to contribute to the quality use of medications. In a collaborative project, staff of the Tasmanian Schools of Pharmacy and Nursing have produced the program PharmaCAL, using HyperCard 2.2 for the Apple Macintosh. A wide range of clinical pharmacology units are covered extensively, concentrating on drugs in common use and based on body systems: cardiovascular pharmacology (including hypertension, cardiac failure and angina); respiratory pharmacology; alimentary tract pharmacology (including peptic ulcer, diarrhea, and constipation); central nervous system pharmacology (analgesia, anxiety and insomnia, depression, psychoses, and epilepsy); antibiotic chemotherapy; and diabetes mellitus. Many color illustrations have been included. Each unit has a set of multiple choice questions to provide feedback to students. The package was evaluated in two ways. First, a questionnaire was used to assess users' opinions of the package. Second, a validated multiple choice test on clinical pharmacology and therapeutics was administered to 24 third-year nursing students before and after a set of sessions using the package and to a control group of 28 nursing students who were not exposed to the PharmaCAL package. The package generally was well received by the nursing students. Clinical pharmacology test scores significantly improved after using the package and were significantly higher than for the control group of students. The program is a useful adjunct to the existing nursing curriculum. It also could be used in postgraduate nursing education and other health sciences.

Gout in the elderly differs from classical gout found in middle-aged men in several respects: it has a more equal gender distribution, frequent polyarticular presentation with involvement of the joints of the upper extremities, fewer acute gouty episodes, a more indolent chronic clinical course, and an increased incidence of tophi. Long term diuretic use in patients with hypertension or congestive cardiac failure, renal insufficiency, prophylactic low dose aspirin (acetylsalicylic acid), and alcohol (ethanol) abuse (particularly by men) are factors associated with the development of hyperuricaemia and gout in the elderly. Extreme caution is necessary when prescribing nonsteroidal anti-inflammatory drugs (NSAIDs) for the treatment of acute gouty arthritis in the elderly. NSAIDs with short plasma half-life (such as diclofenac and ketoprofen) are preferred, but these drugs are not recommended in patients with peptic ulcer disease, renal failure, uncontrolled hypertension or cardiac failure. Colchicine is poorly tolerated in the elderly and is best avoided. Intra-articular and systemic corticosteroids are increasingly being used for treating acute gouty flares in aged patients with medical disorders contraindicating NSAID therapy. Urate-lowering drugs are indicated for the treatment of hyperuricaemia and chronic gouty arthritis. Uricosuric drugs are poorly tolerated and the frequent presence of renal impairment in the elderly renders these drugs ineffective. Allopurinol is the urate-lowering drug of choice, but its use in the aged is associated with an increased incidence of both cutaneous and severe hypersensitivity reactions. To minimise this risk, allopurinol dose must be kept low. A starting dose of allopurinal 50 to 100mg on alternate days, to a maximum daily dose of about 100 to 300mg, based upon the patient's creatinine clearance and serum urate level, is recommended. Asymptomatic hyperuricaemia is not an indication for long term urate-lowering therapy; the risks of drug toxicity often outweigh any benefit.

It has been reported that some natural catastrophes increase morbidity rates for illness. In this study, we investigated the impact of the 1995 Hanshin-Awaji earthquake on morbidity rates for various illnesses by analysis for correlations between the extent of damage due to the earthquake and occurrences of various illnesses. We searched the medical records of 1948 patients hospitalized due to illness in 48 hospitals during the first 15 days after the earthquake. In each of 14 affected areas, the hospital admission rate and estimated morbidity ratio for each illness were calculated. Destruction ratios were determined based upon the number of dwellings completely destroyed in each area. For total illnesses and each major illness, linear regression analyses were performed comparing hospital admission rates, estimated morbidity ratios, and destruction ratios. Hospital admission rates and estimated morbidity ratios among the 1948 patients were significantly correlated to destruction ratios. With pneumonia, dehydration, acute heart failure, asthmatic attack, and peptic ulcer, hospital admission rates and estimated morbidity ratios were significantly related to destruction ratios, while no significant correlations between estimated morbidity ratios and destruction ratios existed for cerebral vascular disease or ischemic heart disease. Peptic ulcer and pneumonia showed especially high correlation values (age- and sex-adjusted R2>0.7). The present study revealed a strong link between the extent of damage due to the catastrophic earthquake and an increase in morbidity rates for acute illnesses, especially peptic ulcer and pneumonia.

Increases in expenditure on medicines above the level of increases in health care are generally, a feature of all Western health systems. From the early 1990's, the average annual growth rate (AAGR) in pharmaceutical expenditure exceeded the AAGR in health among all the European member states 1. In Ireland, the expenditure on drugs, as a percentage of health care spending, was 7.1% in 1987 compared with 9.2% in 1997. The state expenditure on medicines increased from 165.8 million Pounds in 1993 to 278 million Pounds in 1998 representing an average increase of 11% each year. All the available evidence indicates that the expenditure on medicines will continue to show real growth, and take an increasing share of the total health care budget. Analysis shows that the main reasons driving such growth include those of "product mix"--the prescribing of newer, more expensive medicines, in addition to the 'volume effect' comprising growth in the number of tablets per prescription. These two factors account for 80% of the observed increase in drug cost 2. Six therapeutic classes accounted for 16 of the top 20 most expensive drugs prescribed under the GMS in 1998 3. These areas can be classified as follows: peptic ulcer disease, asthma, hypertension/cardiac failure, antidepressants, anti inflammatory and lipid lowering drugs. In this article we discuss the clinical evidence base, and the pharmacoeconomic implications of lipid lowering therapy in this country.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are a frequently prescribed group of highly effective drugs of which the most well-known side effect is gastrointestinal peptic ulcer. However, NSAIDs have additional renal, cardiovascular, hematological, dermatological, and neurological side effects. Although the spectrum of side effects is slightly different between the conventional NSAIDs and the recently developed cyclooxygenase 2 (COX-2) inhibitors, their overall spectrum is quite similar. Aim of this review is to summarize the current knowledge about NSAIDs and their effects on patients with cardio- or cerebrovascular disorders. NSAIDs interact with many drugs which are used in patients with cardio- or cerebrovascular disorders: They attenuate the effects of diuretics, betablockers, ACE inhibitors and AT-2 blockers, thus leading to uncontrolled hypertension or aggravation of heart failure. They increase digoxin levels, potentiate the effect of oral anticoagulants and interact with platelet inhibitors, thus leading to a higher bleeding risk. There are indications that NSAIDs may induce hypertension in normotensives and that COX-2 inhibitors may lead to an increased rate of myocardial infarction and strokes. Based on these data it is recommended that NSAIDs should be avoided in patients with cardio- or cerebrovascular disorders and alternative pharmaceutical, physical or surgical therapy should be applied. If NSAIDs are inevitable, their side effects should be well monitored; they should be prescribed with caution when given in combination with diuretics, betablockers, ACE inhibitors, AT-2 blockers, digitalis, oral anticoagulants and platelet inhibitors. COX- 2 inhibitors should be avoided in patients with known coronary or cerebrovascular disorders. In patients with uncontrolled hypertension or worsening of heart failure, unreported NSAID-use should be considered. Generally, there is a need to develop further analgetic drugs without the described side effects for patients with cardio- and cerebrovascular disorders.

Until recently, national coding and analysis of routine mortality statistics in most countries included only underlying cause of death. There were changes in the rules for selection and coding of underlying cause in England in 1984 and 1993. We report on trends in mortality rates in an English region from 1979 to 1998, comparing multiple-cause and underlying-cause coded rates, for individual diseases that were affected by coding changes. Among many others, these include pneumonia, venous thromboembolism, heart failure, respiratory distress syndrome, tuberculosis, diabetes, dementia, alcohol and drug abuse, epilepsy, multiple sclerosis, stroke, asthma, peptic ulcer, appendicitis, and cancers of the breast, colon and prostate. Comparisons over time of mortality rates based on underlying cause alone will be misleading when the time-period crosses years in which rules changed for selecting underlying cause.
