We review the results of treating the local effects of 26 cases of inoperable colorectal cancer with Nd:YAG laser. There were 16 men and 10 women of mean age 75, with 17 (65%) rectal, eight (31%) sigmoid and one (4%) ascending colon cancer. They presented with symptoms primarily of obstruction in 12 patients (46%), bleeding in 10 (39%) and diarrhoea in four (15%). Initial therapy to relieve symptoms required a mean of 1.5 (1-3) laser treatments over a mean of 1.5 (1-2) weeks. Twelve patients (46%) had total relief and 12 (46%) had partial relief. Sixteen patients received follow-up maintenance therapy, with laser treatments performed over a mean interval of 7.3 (1-20) weeks. One died at first follow-up treatment; all but two of the others were well maintained by laser treatment alone. Three patients (12%) suffered complications, with two deaths (8%), one due to cardiac failure and the other due to stercoral perforation of the colon. Four patients remained alive after a mean follow-up period of 51 (9-84) months. The mean survival of the others was 5 (0-23) months. Laser palliation for colorectal cancer is efficacious and relatively safe, allows improved quality of survival in 92% of patients after initial treatment, and, alone, can satisfactorily keep patients relatively free of local symptoms in 88% of patients surviving into the follow-up period.

In order to examine the clinical characteristics and genetic background of secondary amyloidosis associated with rheumatoid arthritis, we analyzed clinical features and HLA typing of 85 patients in a multicenter study. Eighty-five patients with secondary amyloidosis associated RA were studied. The diagnosis of secondary amyloidosis were made on histological findings by biopsy or autopsy. The most common biopsy site was gastrointestinal tract (79.5%). Clinical symptom and the frequency at the time of diagnosis were; diarrhea (35 cases), abdominal pain (22 cases) and vomiting and nausea (16 cases). Abnormalities and the frequency in a laboratory test included proteinuria (49 cases), increased serum creatinine (32 cases), anemia (30 cases) and hematuria (15 cases). Twenty-eight patients were dead and 57 patients were alive at the time of the study. The average duration between diagnosis of amyloidosis and death was 19.4 +/- 18.5 (SD) months among the dead patients. The average duration after diagnosis of amyloidosis was 24.2 +/- 19.5 (SD) months in surviving patients. The causes of death were renal failure complicated with heart failure (6 patients), heart failure alone (3 patients) and renal failure alone (2 patients). Fifty-nine patients in the control group who were negative to amyloid deposition on biopsies at more than one site in the gastrointestinal tract, were clinically compared with patients in the amyloidosis group. No difference were noted in the age of RA occurrence and the stage between the two groups. As to the class, however, the number of patients with severe functional disorder (class 3 or severe) was larger in the amyloidosis group. There were no significant difference between the two groups in Lansbury's activity index. On hematology, biochemistry and urinalysis, the incidences of increased white blood cell count, anemia, increased platelet count, increased serum creatinine, hypoproteinemia, hypoalbuminemia, increased IgA, and increased urine and blood BMG were statistically significantly higher in the amyloidosis group than in the control group. HLA-A, -B, -C, and DR-locus antigens were compared in the 53 patients in the amyloidosis group and in the 59 subjects in the control group. There were no significant differences in frequency of HLA-A, and -B antigens between two groups. Frequency of CW7 antigen was significantly decreased in the amyloidosis group (13.2%) than in the control group (39.0%). Frequency of DR1 antigen was decreased in the amyloidosis group (3.8%) than in the control group (22.0%), although the difference was not significant. These findings suggest the possible involvement of genetic factors in the occurrence of amyloidosis. It is suggested that the occurrence of amyloidosis is suppressed by some genes which are linked with CW7 antigen.

Aluminium phosphide (AIP) is a poison used in Denmark to combat moles and vermines e.g. in granaries. On contact with water AIP releases phosphine gas, which has a strong cytotoxic action. We describe a lethal poisoning in a healthy 83 year old man, caused by ingestion of pellets containing AIP. After ingestion the primary symptoms were burning retrosternal pain, severe vomiting and diarrhoea which progressed to cardiac failure, arrhythmias and severe metabolic acidosis. The patient and his excreta smelled of garlic, ammonium carbide and decaying fish, which is characteristic of this poisoning. In spite of intensive care support the patient died in cardiac and respiratory failure 17 hours after ingestion of the pellets. Treatment is supportive. Knowledge about the toxicity of AIP is described and discussed.

A 14-year-old, spayed female Jack Russell terrier with a six month history of weight loss, lethargy, intermittent vomition and diarrhoea was diagnosed as having a chronic impaction of the caecum with mineralised faecal material. Diagnosis was based on the clinical findings and both survey and positive contrast radiographic studies. The diagnosis of caecal impaction was confirmed at surgery and a typhlectomy was performed with the aid of a linear stapler. Histopathology of the caecum confirmed the impaction to have resulted from faecolithiasis. The dog made a full recovery from the procedure, showing no recurrence of the clinical signs until euthanasia three months postoperatively for probable heart failure associated with mitral regurgitation.

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.

The moose (Alces alces L.) in an acid rain affected region in south-west Sweden has developed a complex disease with numerous clinical signs, most of which are consistent with those of secondary copper (Cu) deficiency and/or molybdenosis in cattle and sheep. The clinical signs of the moose disease reported to date include diarrhoea, anorexia, emaciation, achromotrichia, alopecia, sudden heart failure and osteoporosis. Findings at necropsy included mucosal oedema, atrophied lymphoid tissues of the mucous membranes of the alimentary tract, neuropathy, neuronal degeneration and uni- or bilateral corneal opacity. In a study of clinically healthy animals from the affected region in Sweden over a 12-year period (1982-1994), the hepatic Cu concentration decreased by 50% and the liver and kidney cadmium (Cd) concentration decreased by 25-35%, while the molybdenum (Mo) concentration increased by 20-40%. These changes are probably related to an increase in the pH of the soil and water in the moose environment and a consequent change in the uptake of these elements by the plants consumed by the moose. It is noteworthy that the occurrence of the disease in the mid 1980s coincided with increased liming undertaken to counteract the noxious effects of acid rain in this region. Clinical signs and lesions of the moose disease resemble those reported for Cu deficiency and/or molybdenosis in cattle and sheep. To elucidate the complex, multi-faceted clinical signs of the moose disease, the clinical signs and necropsy findings are discussed in relation to the biochemical functions of certain well-known Cu-dependent enzymes, e.g. depigmentation of hair due to depressed tyrosinase activity, osteoporosis by depressed lysyl oxidase activity, sudden heart failure due to decreased activity of lysyl oxidase, cytochrome c oxidase and Cu/Zn-superoxide dismutase; in addition, mucosal lesions and ulcerations due to loss of activity of diamine oxidase as well as of lysyl oxidase and cytochrome c oxidase. It is concluded from the present findings that the moose disease is most probably a Cu deficiency and/or a molybdenosis-type syndrome.

The efficacy and safety of the angiotensin converting enzyme inhibitor enalapril in dogs with naturally acquired class III or class IV heart failure was evaluated in this study. Eighteen small-breed dogs with insufficiency of their mitral valves, but without other diseases were included in this study over a period of six months. When necessary due to massive pulmonary edema or high serum potassium concentrations, furosemide was added to the therapy with enalapril. No other drugs, including digitalis, were used in this study. The treatment was followed by anamnesis, clinical examinations, electrocardiography, radiography, echocardiography and laboratory diagnosis. Examinations were performed before treatment and after one week, after six weeks and after six months of treatment. 72% of the dogs improved in NYHA classification until the end of the study (p < 0.05). The incidence of seizures due to syncopes or severe respiratory distress decreased during this study (p < 0.01). For 28% of the dogs this treatment was not successful. In the electrocardiographic, radiographic and laboratory examinations statistically significant changes could not be recorded. The decrease in heart rate did not reach statistical significance. The echocardiographic investigation evaluated a significant decrease in fractional shortening and in the diastolic diameter of the left ventricular wall (p < 0.05 respectively p < 0.01), but no significant change in the diastolic or systolic diameter of the interventricular septum. The average oral dose of enalapril was 0.38 mg/kg body weight b.i.d., the average dose of furosemide was 0.37 mg/kg body weight b.i.d. in the first week of the study and was raised to 0.74 mg/kg body weight b.i.d. until the end of the study. Side effects like diarrhea, vomiting or reduced appetite did not increase during the course of the study. However one dog was excluded from the study because of repeated vomiting after six weeks of treatment. This study shows the beneficial clinical and hemodynamic effects and the security of the therapy with enalapril for dogs with heart failure due to mitral insufficiency.

A 74 year old patient with diabetes mellitus was hospitalized because of nausea, recurrent vomiting and increasing fatigue. Shortly before admittance the patient had diarrhea. He also reported a recent onset of aversion against meat consumption. Clinical investigation revealed a possible right-sided paraumbilical abdominal tumor, normal bowel sounds, a vascular bruit and a normal white blood count with increased band forms. During hospitalisation the general condition of the patient deteriorated rapidly with fever and increasing numbers of immature granulocytes. The patient finally died under the symptoms of a paralytic ileus with hypotonia and hypoglycemia. Autopsy revealed a fist-sized stenosing tumor in the cecum with the histology of a mainly well differentiated, cylindrocellular adenocarcinoma. As immediate cause of death a bilateral paracentral lung embolism with pulmonary edema was found, the latter probably as immediate consequence of preterminal heart failure.

A 47-year-old multiple trauma patient, experiencing a C. Difficile colitis with diarrhoea, developed diffuse oedema with peritoneal and pleural effusion due to global heart failure. Selenium deficiency, reported in trauma patients, may explain the occurrence of cardiomyopathy. The role of selenium in cardiac dysfunction and the various situations inducing a selenium deficiency are discussed.

Carcinoid tumours in the intestine are slowly growing neuroendocrine tumours. Patients as a rule report symptoms of the carcinoid syndrome: attacks of diarrhoea and of flushing. When the earliest symptoms manifest themselves, metastases are already present, virtually always localized in the liver. At a late stage, heart failure may occur, difficult to treat and caused by fibrosis of the tricuspid valve in the presence of protractedly raised blood serotonin levels. To diagnose carcinoid tumours, use is made of radioactive substances binding to hormone receptors such as 131I-MIBG and 111-In-octreotide. When multiple metastases exist, only palliative treatment is possible. The drugs used are the somatostatin analog octreotide, interferon alpha, radioactive MIBG and non-radioactive MIBG; these drugs may also be used in combination. The therapies mentioned have approximately the same effect: symptoms improve in 60-80%, while 30-50% show a biochemical response, i.e. decrease of the number of breakdown products in the urine of the hormones produced by the tumour; tumour size decreases in 0-12%.
