Depressive symptoms, due either major depression or clinically significant, subsyndromal depression, occur commonly in the course of Alzheimer's disease. For a variety of clinical and methodological reasons, this remains an area that begs for new investigation. At the very least, these depressive symptoms should be viewed as a cause of significant and treatable "excess disability" (Kramer and Reifler, 1992). Demented patients with clinically significant depression (e.g., depressed mood, significant loss of appetite, insomnia, fatigue, irritability, and agitation) should be considered for a trial of antidepressant therapy, even when they fail to meet full diagnostic criteria for major depression. These symptoms will, in most instances, respond to antidepressant therapy. The "rules" for treatment of depression in dementia are slightly different than for cognitively intact patients: (a) start low, go slower, (b) pay attention to cognitive toxicity of all medication combinations, and (c) depressive symptoms do not persist as long as in cognitively intact patients. Current treatments, especially those SSRI's like fluoxetine and sertraline that have cognitive enhancing effects, should be considered the "first line" antidepressants. We need to emphasize early detection and treatment of depressive symptoms in dementia in all arenas.

Many people living with HIV use marijuana to manage agitation, spasms, chronic pain, depression, nausea arising from chemotherapy, and loss of appetite. Concerns over the use of marijuana or dronabinol (a pharmaceutical version of tetrahydrocannabinol or THC) include potential contamination from pesticides or other chemicals used in the growing process, and the potential of increasing the likelihood of lung infections. Use of THC is associated with reduced levels of testosterone and may have similar effects on other hormones in women. THC can also interact with other mood-altering medications such as Valium, librium, Xanax, seconal, Nembutal, or phenobarbital, by exaggerating their effect.

Managing the symptoms of advanced disease at the end of life is one of the most challenging aspects of medicine for most clinicians. Traditional textbooks provide limited resources for treating patients at this stoichiometric point in their disease. This article provides an overview in the treatment of common symptoms at the end of life, such as anxiety, anorexia and cachexia, constipation, delirium, dyspnea, fatigue and asthenia, nausea and vomiting, malignant intestinal obstruction, and terminal restlessness. By addressing these symptoms, the physician can play a key role in the patient's achievement of a peaceful, symptom-free, and dignified death in the setting of their choice.

The bi-directional nature of the neurovegetative symptoms of depression, as well as the differential response to antidepressant medications, underscore the existence of possible subtypes of this disorder. This study surveyed 56 physicians practicing psychiatry in Hawaii for opinions regarding the most effective antidepressant medication for the following symptoms: hypersomnia vs. insomnia, psychomotor agitation vs. retardation, and gain vs. loss of appetite or weight. Fluoxetine was found to be the drug of choice for weight and appetite gain, hypersomnia, and psychomotor retardation. Mirtazapine was viewed as most effective for weight and appetite loss. Trazodone was found most effective for insomnia and nefazodone for psychomotor agitation. It is concluded that subtyping of depression should be investigated at the symptom level and the generalizability of the effects of each specific compound should be tested.

The therapeutic use of methylphenidate for the management of attention-deficit hyperactivity disorder in children is increasing. As therapeutic use increases, the risk increases of unintentional overdoses, medication errors, and intentional overdoses caused by abuse, misuse, or suicide gestures and attempts. Side effects during therapy, which include nervousness, headache, insomnia, anorexia, and tachycardia, increase linearly with dose. Clinical manifestations of overdoses include agitation, hallucinations, psychosis, lethargy, seizures, tachycardia, dysrhythmias, hypertension, and hyperthermia. Methylphenidate tablets can be abused orally, or they can be crushed and the powder injected or snorted. Despite its abuse potential, there is disagreement regarding the extent to which methylphenidate is being diverted from legitimate use to abuse in preteens and adolescents.

The aim of this study was to examine whether the co-occurrence of disturbed sleep and appetite loss, two commonly encountered somatic symptoms of depression, can differentiate the clinical expression of depressive episodes between bipolar (BP) and unipolar patients (UP). Forty BP and 40 UP outpatients were interviewed through the Schedules for the Clinical Assessment in Neuropsychiatry (SCAN) and the presence of sleep disturbance and appetite loss during their most severe depressive episode was determined. Other variables studied were patients' gender and age, clinical characteristics related to the course of the disease (age at onset, duration of illness, and number and frequency of depressive and manic episodes), severity of the worst major depressive episode, and presence or absence of certain associated symptoms during that episode (loss of energy, low interest, feelings of guilt and/or self-reproach, impaired concentration, suicidal ideation, and agitation or retardation). Appetite loss was found to be more frequently present in UP (78%) than BP patients (55%, P<.05). No significant difference in the occurrence of sleep disturbance was found between the two groups. Among BP patients, appetite loss was present in 73% of those with sleep disturbance vs. 33% of those without (P<.02), while no such difference in co-occurrence of sleep disturbance and appetite loss was noticed among UP patients (74% vs. 85%, respectively, n.s.); this finding did not seem to be related to differences in severity of depression among UP and BP patients. Furthermore, those BP patients with co-occurrence of the two somatic symptoms complained also of loss of energy and low interest more often than those without (P<.01 and P<.05, respectively). No similar differences were observed among UP patients. The results of the present study suggest that the pathophysiological mechanisms underlying depressive episodes may differ between BP and UP affective disorder, and that those BP patients with simultaneous occurrence of sleep disturbance and appetite loss can be considered to belong to a particular nosologic subgroup with potential therapeutic and prognostic implications.

The aim of this study was to describe the epidemiological features of agitation and aggressiveness in elderly individuals living in French nursing and retirement homes in the year 2000. Data were collected on the type, time of onset, and duration of symptoms, medical evaluation and treatment, and medical and psychiatric comorbidities of the elderly patients. The most frequently reported behavior was verbal aggressiveness and the least reported behavior was physical aggressiveness. A triggering factor initiating the symptoms of agitation or aggressiveness was reported in 61% of the cases. In 61% of the study population, there were several morbidities reported as caused by the agitated or aggressive behavior (anorexia, weight loss, dehydration). A specialist was consulted for nearly half of the agitated or aggressive patients. For 55% of the patients, a new medication regimen was started or the administration of previous medications was modified, the most frequently prescribed drugs being antipsychotics. The results of our study and others show that agitation and aggression have a substantial impact on the lives of the elderly population, as well as on the lives of their family members and caretakers.

Low leptin levels are an endocrinological hallmark of acute anorexia nervosa (AN); a subthreshold leptin secretion in adipocytes as a consequence of a reduced energy intake is presumed to be the major trigger of the adaptation of an organism to semistarvation. The aim of the current study is to define symptoms of AN that are potentially linked to low leptin levels. For this purpose, quantitative somatic and psychopathological variables were obtained in 61 inpatients with acute AN (study group 1) upon referral for inpatient treatment, and they were concomitantly blood sampled to allow determination of serum leptin levels. Correlations between these variables and logarithmic transformed (lg10) leptin levels were descriptively assessed. Apart from the well-known correlations between leptin levels and anthropometric measurements, the strongest correlation was observed between lg10 serum leptin levels and expert ratings of motor restlessness (r = -0.476; nominal P = 0.003) upon use of visual analog scales. We thus generated the hypothesis that physical activity levels in AN patients are related to serum leptin levels. This hypothesis was tested in an independent study group of 27 adolescent inpatients (study group 2) who were also assessed upon referral. Physical activity levels, which, in this study group, were assessed with the activity module of the expert rating form of the Structured Inventory for Anorexic and Bulimic Syndromes, were significantly correlated with lg10 leptin levels (r = -0.51; one-sided P = 0.006). A regression model based on the independent variables body mass index and lg10 leptin levels explained 37% of the variance of physical activity (R(2) = 0.37; P = 0.003); only the lg10 leptin levels contributed significantly to the variance (P = 0.003). Our results suggest that, similar to semistarvation-induced hyperactivity in rats, hypoleptinemia in patients with AN may be one important factor underlying the excessive physical activity.

Somatic symptoms are known to be the major manifestation in patients with depression. The aim of the present study was to investigate the major somatic and psychiatric symptoms associated with depression in each sex. Patients with a DSM-IV diagnosis of depressive disorders (n=335) and comparison patients without depression (n=425) among new outpatients in an urban hospital medical setting were eligible for study. The relationship between the three most distressing subjective symptoms at the first visit, confirmed by the patient's description on a health questionnaire and the admitting physician's interview, and depression was investigated in each sex. Most (77.4%) of the complaints in patients with depression were somatic. In a simple logistic regression analysis, diarrhea, excessive sweating and psychomotor retardation in men, and headache, depressed mood and grief in women were associated with depression. In multiple logistic regression analysis, diarrhea, excessive sweating and weight loss in men, and headache, dysesthesia and grief in women, as well as sleep disturbance, loss of appetite, general fatigue, loss of interest and agitation in both sexes, were statistically significantly associated with depression. Fever in men was also associated with depression by Fisher's exact test.

A 37-yr-old female Asian elephant (Elephas maximus) presented with anorexia, restlessness, and dark-colored urine. Urinalyses showed hematuria, leukocyturia, isosthenuria, proteinuria, granular casts, and no calcium oxalate crystals. Bloodwork revealed azotemia. Urine culture revealed a pure growth of Streptococcus zooepidemicus resistant to sulfamethoxazole-trimethoprim but susceptible to cephalosporins. A presumptive diagnosis of pyelonephritis was made based on bloodwork, urinalysis, and urine culture. The animal was treated with intravenous ceftiofur, and intravenous and per rectum fluids were given for hydration. The elephant's attitude and appetite returned to normal, the abnormal blood parameters resolved, and urinary calcium oxalate crystals reappeared after treatment, supporting presumptive diagnosis. Follow-up ultrasonography revealed an abnormal outline of both kidneys with parenchymal hyperechogenicity and multiple uterine leiomyomas.
