A diagnosis of cholecalciferol toxicity in a young dog was made on the basis of adequate history and the finding of extremely elevated serum calcium levels. The traditional treatment of fluid therapy, diuresis and corticosteroids resulted in lowering the serum calcium levels over a 5-d period. The dog displayed clinical signs of severe depression, anorexia and intermittent vomiting during this time interval. Serum calcium levels rose on day 6 and remained elevated up until the dog was euthanized on day 9. Gross and histopathological examinations revealed diffuse metastatic mineralization throughout the body, particularly involving the lung, kidney, atria and stomach. The amount of cholecalciferol ingested was determined well below the lethal dose reported in dogs. This report indicates that young dogs may be much more susceptible to the lethal effects of this compound than initially believed.

Sharp pain is conducted rapidly by myelinated delta A fibers and diffused pain slowly by nonmyelinated C fibers to pseudobipolar neurons in the posterior ganglion and from there to neurons located in the posterolateral horn of the spinal cord. From here on nociferous impulses are transmitted by excitatory peptides (e.g. substance P) or amino acids (e.g. glutamate, aspartate) through interconnecting neurons of the pain pathways, primarily on the contralateral side, to the brain stem and from there to the sensory cortex, where they are appreciated and acted upon. There are specific inhibitory receptors located on axon terminals, near to the release sites of the excitatory amino acids and peptides. Stimulation of these receptors by their appropriate ligands such as endogenous (e.g. enkephalis, endorphins) or exogenous opioids, clonidine, serotonin, somatostatin inhibits the release of excitatory neurotransmitters and relieves pain. There are at least 3 different opioid receptors, called mu-, kappa- and delta-receptors in the spinal cord. These can be differentiated from one another by their specific affinity toward different endogenous or exogenous opioids and the pure narcotic antagonist, naloxone. It appears that the nociferous impulses transmitted by parallel pathways equipped with different inhibitory receptors have to be integrated to produce pain sensation and partial inhibition of transmission in different pathways or complete inhibition in one of the pathways may relieve pain. In recent years the concept of "selective spinal analgesia" has been applied clinically for the relief of postoperative, obstetrical and chronic pain. At first it was expected that the intrathecal or peridural administration of morphine will produce analgesia without the side effects of systemically administered morphine. It soon became evident, however, that intrathecally and peridurally administered morphine after several hours of delay reaches the fourth ventricle and by stimulating mu-receptors may cause respiratory depression and other undesired effects (e.g. nausea, vomiting, pruritus). Several different approaches are being investigated for the production of selective spinal analgesia without side effects. They include: a. the use of more lipophilic, long-lasting opioids (e.g. lofentanil) which would be almost completely absorbed by the spinal cord and therefore would not reach the medullary centers; b. the development of opioids with specific affinity to kappa- and for delta- and little or no affinity to mu-receptors, primarily responsible for side effects; and c. combining lower doses of opioid agonists with alpha 2-adrenergic agonists (e.g. clonidine) or with somatostatin. It is conceivable that in the not-too-distant future, it will be possible to achieve through these measures, selective spinal analgesia without side effects.

Efficacy and side effects of a continuous infusion of sufentanil following epidural administration of a single dose of 30 micrograms of the opioid were studied in 28 patients undergoing laparotomy. Patients were divided into two groups treated with either 10 micrograms/h (n = 13) or 15 micrograms/h (n = 15) and compared with regard to sufentanil plasma levels, side effects and changes in blood gases. The analgesic effect of 15 micrograms/h was slightly better than that of 10 micrograms/h. There were few side effects during continuous administration of the high- or low-dose sufentanil: in some cases nausea (4/13 and 1/15) and vomiting (3/13 and 1/15) occurred. After the injection of a bolus of 30 micrograms sufentanil, a dose chosen according to current recommendations, a quick onset of analgesia was noted, but also sedation and respiratory depression with apneic intervals lasting up to 30 s, demonstrating both the efficacy and the possibility of unwanted and even harmful side effects associated with this kind of administration. During long-term infusion, after about 20 h PaCO2 and respiratory rate were significantly different between the two groups, which could be explained by differences in sufentanil plasma levels and a somewhat higher level of postoperative pain in the group receiving 10 micrograms/h.

In a comparison of nutritional management (NM) and stress management (SM) for treatment of bulimia nervosa, 55 female patients were randomly assigned to either treatment. Therapy consisted of 15 sessions in a group over three months, by the end of which, patients under both treatment conditions showed a significant reduction in the frequency of binge eating and vomiting and a significant improvement in various psychopathological features such as body dissatisfaction and depression. All improvements were maintained over 12-month follow-up NM produced a more rapid improvement in general eating behaviour, a faster reduction in binge frequency and a higher abstinence rate from binge eating. SM led to greater positive changes in certain psychopathological features such as feelings of ineffectiveness, interpersonal distrust and anxiety. NM should be regarded as a necessary first intervention in all bulimic patients. Further psychological therapy, such as SM, is indicated as well for some patients, depending on their specific psychological difficulties.

This study examines clinical features of late onset anorexia nervosa. This involved the scrutiny of a large database of patients with anorexia nervosa comprising data gathered at standardized initial assessments over the period 1960-1990. Patients with a late onset were compared to other selected patient samples. The population comprised 12 patients with a first onset of anorexia nervosa at or after the age of 30, 415 patients with an onset after 15 but before 20 and 9 patients with an onset after 15 but before 20 and matched for age at presentation with the late onset group. Features studied included age at menarche, age at onset of anorexia nervosa, age at presentation, duration of illness, weight at presentation, lowest adult weight, highest weight, weight at onset of illness, marital status and parity. Patients with an onset of anorexia nervosa after the age 30 comprised 2% of the total female patient sample. Though such patients were rare, their clinical features were very similar to those of typical patients with adolescent onset. Notably, young and late onset patients had similar durations of illness prior to presentation, and similar proportions had bulimia and defensive vomiting. Feared sexuality, no longer necessary for childbearing, emerged as being of apparent aetiological significance in the late onset group, with the disorder embodying its rejection, as often also seems to be the case with earlier onset. The late onset cases were hard to diagnose and had a poor outcome. The study underlines the importance of considering the diagnosis of anorexia nervosa in older patients, even if there is no earlier history of anorexia nervosa. Such patients are likely to find it easier to conceal the psychological origins of their problem behind the possibility of a primary physical illness, or behind psychiatric diagnoses such as depression, the treatment of which may not threaten their avoidance of normal body weight.

Poisoning is a significant problem in the elderly. The majority of poisonings in older people are unintentional and may result from dementia and confusion, improper use of the product, improper storage or mistaken identities. Depression is also common in the elderly and suicide attempts are more likely to be successful in this age group. The elderly patient's recuperative abilities may be inadequate as a result of numerous factors including impaired hepatic or renal function as well as chronic disease processes. General management of poisoning in the elderly parallels management of younger adults, but it is especially important to ascertain underlying medical conditions and concurrent medications. In most poisonings, activated charcoal and cathartic are sufficient. Haemodialysis or haemoperfusion may be required at lower plasma drug concentrations in elderly patients. While the specific indications for antidotes are the same for all age groups, dosage alterations and precautions may need to be considered in the elderly. Drugs most often implicated in poisonings in the elderly include psychotherapeutic drugs, cardiovascular drugs, analgesics and anti-inflammatory drugs, oral hypoglycaemics and theophylline. Cardiovascular and neurological toxicities occur with overdoses of neuroleptic drugs and, more frequently and severely, with cyclic antidepressants. Patients with pre-existing cardiovascular disease are at particular risk of worsening ischaemic heart disease and congestive heart failure. Benzodiazepines only appear to produce significant toxicity during long term administration or in combination with other CNS depressants. Digoxin can cause both chronic and acute intoxication, most seriously cardiac toxicity including severe ventricular arrhythmias, second or third degree heart block or severe refractory hyperkalaemia. Immune Fab antibody is indicated for the management of digoxin toxicity, although patients dependent on the inotropic effect of digoxin may develop heart failure after digoxin Fab antibody administration. Nitrates can cause toxicity including headache, vomiting, hypotension and tachycardia from excessive sublingual, transdermal or intravenous doses. Conduction disturbances and hypotension occur with overdoses of antihypertensive drugs; these effects are mild with angiotensin converting enzyme (ACE) inhibitors, occasionally severe with beta-blockers and of significant concern with calcium channel antagonists. The elderly commonly use aspirin and other salicylates, are more likely to develop chronic intoxications to these agents, and are more susceptible to severe complications such as pulmonary oedema. Salicylate poisoning, recognition of which is often delayed, should be considered in elderly patients with neurological abnormalities or breathing difficulties, especially in the setting of acid-base abnormalities. The clinical effects of NSAID overdose are mild and usually involve the central nervous system and gastrointestinal tract.(ABSTRACT TRUNCATED AT 400 WORDS)

The large number of antidepressants available provides a wide range of choice. While clinical effectiveness is the most important consideration, toxicity in overdose must be considered in the risk-benefit assessment of each antidepressant. There are almost 300 deaths each year in Britain from tricyclic overdose, and very few deaths from newer antidepressants. Fluvoxamine appears to have low toxicity in overdose. Symptoms are often minimal: nausea, vomiting, dizziness and somnolence. There is one reported case of prolonged cerebral depression after ingestion of 5.5 g. Overdoses of up to 9 g have produced minimal symptoms and full recovery. No deaths from overdose with fluvoxamine alone have been reported in the literature, although one death certificate in Britain has mentioned fluvoxamine as the cause of death. Fluvoxamine appears to be a valuable alternative to the tricyclic antidepressants, and has a high margin of safety in overdose.

To determine the lowest effective dose of epidural sufentanil given for analgesia, 41 patients undergoing elective abdominal gynecologic surgery during continuous epidural anesthesia (lidocaine 2%) were randomly assigned to one of four postoperative treatment groups. Patients received an epidural bolus of either 25 (group A), 40 (group B), 55 (group C), or 70 micrograms (group D) sufentanil in 10 mL of saline. They were evaluated for the next 8 h using a 10-cm visual analogue scale. Except for two individuals in group A, all patients achieved a visual analogue scale score of 1 cm or less during the study interval. The onset of analgesia was most rapid in the two higher dose groups (A vs C and D; P less than 0.05). Pairwise comparison between groups showed a significant difference in the time needed to achieve maximum pain relief between the lowest and highest treatment groups (A vs D; P less than 0.05). Duration of analgesia was also significantly longer in groups C and D than in group A (208.0 +/- 21.1 and 224.0 +/- 14.7 vs 140.0 +/- 10.7 min; P less than 0.05). There were no differences among groups with regard to mean respiratory rate, level of sedation, 24-h narcotic requirements, or incidence of nausea, vomiting, and pruritus (P = NS). A single patient in group D suffered profound respiratory depression within seconds of administration. We conclude that, in patients recovering from lower abdominal surgery, a single 40-55-micrograms epidural bolus of sufentanil provides 3-3.5 h of effective analgesia, and that larger doses are not warranted.

Between May-October 1989, physicians selected 50 mothers of low socioeconomic and educational background with Down Syndrome (DS) children who attended the Genetic Clinic at the Institute of Child Health and Hospital for Children in Madras, India for a study to evaluate their knowledge, attitude, and practices. The study consisted of a preevaluation, education and genetic counseling, and reevaluation at 3 months. Only 18% of the mothers knew that their children had DS. Physicians had diagnosed it at birth in these cases. Most mothers (62%) came to the hospital because they had noticed developmental delay. Most (64%) did not know what caused DS. 36% believed DS occurred due to various prenatal events including poor diet, weakness, injury, abortifacients, abdominal pain, vomiting, and long birth intervals. Family tended to blame the mothers for the child's disability which evoked social and emotional problems. When 52% learned of their children's handicap, they suffered depression. 80% did not know that their children required special care. Once learning this, however, most mothers (88%) wanted either themselves or someone else to care for their children. 96% breast fed their children and weaned them properly. 90% of the children had received immunizations. After genetic counseling and health education, all mothers understood their children's condition. 75% worked with their children at home doing passive exercises and developing their vocabulary. The rearing practices of the DS children were the same as those of the normal children. The mothers learned via the health education and genetic counseling that family planning and amniocentesis could prevent the birth of a DS child. The health education and genetic counseling program improved mothers knowledge, attitude, and practices toward child-rearing practices of DS children. This program can be duplicated among poor and illiterate parents in rural areas.
