Comparison of a series of twenty-four wrist-cutters with a control group of self-poisoners showed a number of significant differences. The wrist-cutters were younger and their acts were regarded as being of low lethality; they are no more likely to have made previous suicide attempts; they complain less often of depression, and more frequently of 'emptiness' and tension as primary complaints. Sudden, unpredictable mood swings are common and there is a greater tendency for their physicians to diagnose personality disorders, often in pejorative terms. They frequently have substantial medical interests and paramedical occupations. A high proportion complain of dysorectic symptoms (anorexia or overeating or combinations of both), use drugs and/or alcohol in excess; show sexual disturbance and distress, and also promiscuity. They more frequently have a negative reaction to menarche and menstruation; have come from broken homes and have experienced parental deprivation. A proportion of the group exhibit difficulty in verbal communication, and absconding from hospital was more common in the group of cutters. Painless cutting after a period of depersonalization, followed by relaxation and repersonalization after bleeding, was the typical pattern.

The objective of this study was to characterize the hemostatic defect in dogs with infectious canine hepatitis (ICH), a naturally occurring viral disease of dogs. Five littermate dogs were inoculated with 10(3) TCID50 of ICH virus intravenously. Two littermates were controls. The clinicopathologic manifestations of ICH were fever, depression, anorexia, hematemesis, melena, widespread mucocutaneous petechiae, prolonged bleeding from venipunctures, faceial edema, leukopenia, and proteinuria. The hemostatic defect of ICH was characterized by thrombocytopenia, abnormal platelet function, prolonged one-stage prothrombin time and activated partial thromboplastin time, normal thrombin times, depressed factor VIII activity, and increased fibrin-fibrinogen degradation products. These findings suggested that the central pathologic mechanism of the abnormal hemostasis in ICH was disseminated intravascular coagulation (DIC). ICH is an example of DIC induced by viral infection. This disease is a suitable model for investigation of the detection, pathogenesis, and therapy of DIC.

A 5-week-old mixed-breed dog was examined because of emaciation and depression associated with chronic anorexia, diarrhea, and vomiting. Its rectal temperature was subnormal and it died on the day of admission. At necropsy, small focal lesions were distributed through the liver. Enteric alterations included catarrhal enteritis with fluid contents, excess production of mucus, and mucosal hyperemia. Microscopically, the hepatic lesions were disseminated foci of coagulative necrosis, with little or no associated inflammatory cell response. Numerous organisms morphologically consistent with Bacillus piliformis were demonstrated within viable hepatocytes at the periphery of the necrotic foci and in the intestinal mucosa. Numerous coccidial forms were found within the epithelial cells of the intestinal mucosa, which was focally necrotic.

The aim of this study is to verify the psychological attitude and the quality of life in patients suffering from chronic respiratory insufficiency. Taking for granted that a bad quality of life is connected with the symptom of a depressed state (loss of appetite, quality of sleep, sexuality, psychomotor slowing down, loss of energy, weariness, reduced interest for the external world, feelings of self-devaluation, reduced working and concentration capacity, complainings of turning over type) we have taken as index of "normal quality of life" the lack of these attitudes correlating them to the clinical symptoms and/or the patient's functional troubles and verifying how much they can affect the psychological features and how much the deterioration of the quality of life. For this reason a questionnaire, taken from the MMPI test (Minnesota Multiphasic Personality Inventory), restricted to the items related to the D scale (depression scale), has been given to one hundred COPD patients who had been examined previously from a clinical functional point of view. In the end, we have drawn our results both on the ground of the answers given by the patients to the single questions and on the grounds of the total score D (= depression index) and relating the previous data with the clinical-functional ones. Finally we have compareted these data with those ones connected with non selected population. So we have succeeded in outlining a psychophysical profile of the patient suffering from chronic respiratory diseases. Such a profile is marked by an objective element, that is pathology, and by a psychological element inserted into the organic one as there is an inter-dependence between pathology and psychological features. From the collected data, we have noted the behavioural spheres which are more upset are working capacities, sleep and mood and these features are directly proportional to the seriousness of the pathology. From a practical and therapeutic point of view, all this can be of great importance.

Borrelia burgdorferi has been implicated as the causative agent of borreliosis in dogs, which is characteristically a limb/joint disorder, but can be associated with multiple-organ dysfunction. Attempts to reproduce this disease by inoculating dogs with B burgdorferi have not been successful. In the study of this report, B burgdorferi from Ixodes dammini ticks was used to induce signs of limb/joint dysfunction, fever, anorexia, depression, and systemic infection in dogs. A pure culture of this bacterium from the blood of an infected dog has been used to fulfill Koch's postulates for B burgdorferi as the causative agent of limb/joint dysfunction associated with borreliosis in dogs.

The RC/79 strain of the Aujeszky's disease virus was able to induce reproductive failure of pregnant gilts intranasally inoculated at different gestation periods. Four gilts 40-46 days pregnant (group A) and 6 gilts 70-73 days pregnant (group B) were instilled with 0.2 ml x 10(5) tissue culture infectious dose 50 (TCID50/0.2 ml) of the RC/79 strain into each nostril. Two gilts 70-73 days pregnant (group C) were used as non exposed controls. The three groups were kept in separated boxes and they were observed for clinical signs of infections and samples were collected for determination of viral shedding every day. Viral isolation was attempted in Vero cells (figure 1). From the 2nd to 7th day after inoculation, groups A and B showed fever anorexia, sneezing, coughing and depression; and viral isolation from nasal swabs was possible in 7 gilts at days 4 to 11, 9 gilts developed neutralizing antibodies. The virus caused fetal reabsorption in swine during the first period of pregnancy (group A), while infection during late pregnancy resulted in still birth or normal pigs and one mummification (group B). The entire a live litter was composed of no more than 8 suckling pigs in both groups. At necropsy virus from turbinates, ovary , placenta, spleen and lung could be isolated only from 3 gilts (group B, table 1). In 5 of 35 stillbirth and alive fetuses virus could be isolated from spleen (100%), lung (80%), liver (60%) and brain (40%) indicating that the virus has the ability to cross the placental barrier thus producing lesions in porcine fetuses and causing reproductive failure in sows (table 2). Tissue specimens from these 35 fetuses were fixed in 10% formalin, included in paraffin sectioned and stained with hematoxylin and eosin. In 13 fetuses microscopic lesions i.e. necrotic foci were found in lung (60%), liver (40%) and spleen (20%), these alterations were coincident with gross lesions in most of them. Inclusion bodies were absent. The gilts organs did not present gross lesions.

Selective serotonin reuptake inhibitors (SSRIs) are a recently developed class of drugs with significantly greater antidepressant efficacy than placebo. Generally, in double-blind comparative trials, all SSRIs demonstrated antidepressant efficacy similar to that of the 'standard' tricyclic antidepressants amitriptyline and imipramine; a meta-analysis of controlled trials found the efficacy of the SSRIs to be equivalent to that of the 2 tricyclics. Nevertheless, because of small patient numbers included in most studies that compare SSRIs with other antidepressants, no definitive statements about relative efficacy can be made. In these studies it is simply possible to state that no statistically significant differences were identified between SSRIs and the comparative antidepressants. Importantly, differences in clinical characteristics exist between the SSRIs-differences in elimination half-life (t1/2 beta) between fluoxetine and/or its metabolite (total t1/2 beta = 330 hours) and other SSRIs (t1/2 beta range = 15 to 30 hours), for example. This has implications in terms of potential drug interactions and must be considered when patients have to be switched to treatment with monoamine oxidase inhibitors. Studies with fluvoxamine have been conducted in both in- and outpatients, whereas trials with other SSRIs have been confined largely to outpatient populations. Fluvoxamine has been associated with a high incidence of nausea (37%), although this may have resulted from high initial dosages (rather than upward dose titration protocols) used in early trials. Of further interest, fluoxetine doses of 20mg may be sufficient to produce a satisfactory antidepressant response, and this SSRI may be particularly useful in patients with chronic retarded depression. More clinical data are required before the efficacy of sertraline and citalopram relative to standard antidepressants can be clearly defined. Preliminary data indicate that SSRIs are effective in the treatment of panic disorder, obsessive-compulsive disorder (OCD), eating (e.g. anorexia and bulimia) and personality disorders (e.g. anger, impulsiveness) and substance abuse (e.g. alcoholism); early results with fluvoxamine in the treatment of panic disorder and OCD, and with fluoxetine in the treatment of bulimia, personality disorders and alcohol abuse, have been encouraging. SSRIs have a more favourable tolerability profile than tricyclic antidepressants and, unlike the tricyclics, are not associated with anticholinergic adverse effects, sedation, cardiotoxicity or weight gain. SSRIs are associated with a relatively high incidence of nausea, particularly if high doses are used at the start of treatment. However, the incidence of nausea appears to decrease as treatment is continued.(ABSTRACT TRUNCATED AT 400 WORDS)

Centrally acting appetite suppressant drugs used in the treatment of obesity fall into 2 broad pharmacological categories; those which act via brain catecholamine pathways and those which act via serotonin pathways. Of the former group, amphetamine and phenmetrazine are no longer recommended because of their stimulant properties and addictive potential. The remaining drugs in this class include amfepramone (diethylpropion), phentermine, mazindol and phenylpropanolamine. All have been shown to reduce appetite and lower food intake, thereby helping obese patients more easily keep to a low-calorie diet and lose weight. They all have some sympathomimetic and stimulant properties. Anorectic drugs which promote serotonin neurotransmission have no such stimulant or sympathomimetic properties. They are fenfluramine, together with its recently introduced dextrorotatory stereoisomer dexfenfluramine, and fluoxetine. They reduce appetite and food intake and are effective in the treatment of obesity. Anorectic drugs should be reserved for those who are clinically at risk from being overweight, and then only as part of a comprehensive weight-reducing programme including regular dietary counselling. Although current licensing regulations only allow their use over a relatively short period (12 to 16 weeks), clinical trials have shown them to be effective over longer periods, particularly in preventing weight regain. Of the compounds currently indicated for use in obesity, dexfenfluramine appears to have the most suitable pharmacological profile, although it should not be given to patients with a history of depression. When used appropriately, appetite suppressants can be of real therapeutic benefit, and pose little risk.

A case of E. canis in a 7 year old intact female bearded collie is described and possible clinical signs of Ehrlichiosis are discussed. Non-specific findings included elevated rectal temperature, depression and anorexia. Additional findings were generalized lymphadenomegaly, myalgia and painful swollen joints. Significant changes in the CBC were leucopenia and thrombocytopenia. The positive E. canis titer of 1:40 and rising titer to 1:160 were specific for Ehrlichiosis. Doxycycline and prednisolone were needed to obtain clinical remission, which underlines, that immune-mediated processes are important in the pathogenesis of Ehrlichiosis.

Three neonatal calves ranging in age from 4 to 14 days were examined pathologically and bacteriologically. The calves showed depression, anorexia, pyrexia, and difficulty or inability to stand followed by cloudiness of the ocular aqueous humor or cornea. Autopsy revealed congestion, petechiae, and cloudy areas in the meninges. Histologically, the central nervous system (CNS) lesions were prominent and limited to the meninges where fibrinous exudate and infiltrations of neutrophils, macrophages, and lymphocytes were present. There were mild or slight degrees of choroid plexitis and ependymitis. Endophthalmitis was seen as a concurrent lesion in all cases. Fibrinous or fibrinopurulent changes were found in the peritoneum and epicardium as well as in several other organs. Numerous Gram-positive cocci were detected in affected areas of the whole body. Bacteriologically, Streptococcus bovis was isolated from all examined materials consisting of the brain, cerebrospinal fluid, ocular aqueous humor, and several other organs. These results suggest that the lesions were associated with infection of the organism and that the present cases were in the process of septicemia.
