Assessing psychiatric illness in geriatric patients can be difficult for a variety of reasons. First, medical comorbidity may obscure the diagnosis. For example, the patient with multiple chronic illnesses will often have many "vegetative" symptoms of either dementia or depression (e.g., fatigue, loss of energy, poor appetite) attributed to the primary medical condition rather than to an underlying psychiatric illness. Second, the phenomenology of psychiatric illness in the elderly is often different. For example, depression in the elderly is often characterized by prominent anhedonia--loss of interest in virtually everything--and physical complaints leading to an unnecessary medical workup. Third, physicians are often reluctant to diagnose new-onset mental illness in their elderly patients. The fear of stigmatizing the patient or physician discomfort with "psychologic language" often results in underdetection of straightforward psychiatric syndromes. This article will focus primarily on detection of 3 of the most common psychiatric syndromes: dementia, depression, and delirium. The field of geriatric psychiatry has done a good job of characterizing the prevalence (Table I) and clinical features of these syndromes. The problem--briefly addressed here--is how to incorporate some of these findings into a busy clinical practice where there is very little time for the assessment of psychiatric symptoms.

Disseminated Mycobacterium avium complex (DMAC) is the third most common opportunistic infection in people with AIDS, infecting up to 50 percent of them. Symptoms include high fever, weight loss, fatigue, diarrhea, poor appetite, night sweats, and anemia. Diagnosis is by blood culture. Results of two recent studies are presented, as well as treatment guidelines issued by a national panel.

Wasting is a severe, dangerous medical condition, and it can occur quickly, even in overweight patients. In wasting, the digestive process is disrupted, and patients lose their ability to absorb necessary nutrients from food. HIV interferes with metabolism, causing the body to burn muscle mass before it burns fat. Additionally, other physical problems can make eating difficult or painful, and the nausea associated with HIV therapies compounds the problem. Several nutritional supplements are recommended for people with weakness, fatigue, or poor appetite. Some are standard supplements intended to boost caloric intake easily, others are modified fat supplements or special formula supplements designed for special purposes.

Rhodiola rosea is a popular plant in traditional medical systems in Eastern Europe and Asian with a reputation for stimulating the nervous system, decreasing depression, enhancing work performance, eliminating fatigue, and preventing high altitude sickness. Rhodiola rosea has been categorized as an adaptogen by Russian researchers due to its observed ability to increase resistance to a variety of chemical, biological, and physical stressors. Its claimed benefits include antidepressant, anticancer, cardioprotective, and central nervous system enhancement. Research also indicates great utility in asthenic conditions (decline in work performance, sleep difficulties, poor appetite, irritability, hypertension, headaches, and fatigue) developing subsequent to intense physical or intellectual strain. The adaptogenic, cardiopulmonary protective, and central nervous system activities of Rhodiola rosea have been attributed primarily to its ability to influence levels and activity of monoamines and opioid peptides such as beta-endorphins.

A 43-year-old woman complained of colicky abdominal pain, followed by numbness, myalgias, and muscle weakness in the four limbs after eating a grouper (Epinepheius spp.). She presented to our hospital 36 hours later with increased myalgias, muscle weakness, and malaise. On examination, the muscle power and sensation in her four limbs appeared to be normal. She was given an intravenous infusion of mannitol 20% (200 ml over 1 hour) and an intramuscular injection of diclofenac (75 mg). Her myalgias then improved and she was discharged. She presented to our hospital again 1 week later with poor appetite, malaise, numbness of the four limbs, and increased muscle weakness. On examination, the muscle weakness was more marked in the lower limbs (4+/5) than in the upper limbs (5-/5) and proximally than distally. She also had some difficulty in getting up from a squatting position. She was given another intravenous infusion of mannitol 20% (200 ml over 1 hour), following which there was subjectively slight improvement in her muscle weakness. Herplasma creatine phosphokinase level was normal. Electromyography performed 4 weeks later revealed no abnormalities. When she was reviewed 45 days after the consumption of the grouper, her muscle weakness and malaise had improved considerably. She could then stand up from a squatting position. However, mild impairment of finger grip was still present. Chronicity of neurological features in other reported cases (e.g., chronic fatigue, relapse of symptoms after exposure to ciguateric fish or alcohol, and peripheral neuropathy) may also indicate a lengthy persistence of ciguatoxins in the body.

The management of metastasis from parathyroid carcinoma (PC) is an unusual challenge. Systemic therapy has minimal effect on the course of the disease and its associated hypercalcemia. Resection of isolated pulmonary metastases is an attractive option in the setting of recurrent hypercalcemia. We report a case of a patient who underwent resection of multiple functional PC pulmonary metastases almost 20 years after the original neck resection. The patient originally presented in 1982 with what was thought to be hyperparathyroidism secondary to a parathyroid adenoma. Surgical exploration revealed the presence of a well differentiated PC. The patient was transiently normocalcemic, but underwent surgical exploration in 1993 and 1996 for recurrent PC in the neck. The patient again improved, but presented in 2001 with diffuse arthralgia, fatigue, malaise, weight loss, and decreased appetite. She was found to have a serum calcium of 12.7 mg/dL and an intact parathyroid hormone of 1542 pmol/L. Computed tomography identified the presence of two right-sided and two left-sided pulmonary masses. Sternotomy with bilateral pulmonary metastectomy was performed. Functional PC metastasis was confirmed on pathological examination. One year following metastectomy the patient is hypocalcemic, requiring oral calcium and vitamin D supplementation. Functional pulmonary metastasis from PC is a rare cause of hypercalcemia. Complete resection of isolated pulmonary metastases can provide effective palliation with long-term survival.

In any given population of free-living individuals 65 years of age and older, a substantial proportion (in the range of 6% to 25%) suffers from many of the elements of the syndrome of frailty. Although the syndrome is complex and still lacks a standard definition, there is a growing consensus about the signs and symptoms as well as the pattern of biological correlates that characterize this disorder. Patients who are afflicted with frailty typically exhibit loss of muscle strength, fatigue easily, are physically inactive, and have a slow-and often unsteady-gait, with an increased risk (and fear) of falling. They are likely to have a poor appetite and to have undergone a recent, unintentional loss of weight. Frail individuals are more likely than the nonfrail to experience impaired cognition and depression. They die sooner. Frailty, of course, is frequently complicated by a variety of coexistent illnesses. Among the biological correlates of frailty are sarcopenia (now readily measurable by dual-energy x-ray absorptiometry [DXA]), osteopenia (with an increased susceptibility to fracture), and activation of the inflammatory and coagulation systems, with a rise in inflammatory cytokines and several markers of coagulopathy. Age-dependent changes in a number of hormones also appear to promote the development of frailty in the elderly, particularly via their effects on muscle mass and strength, bone density, and by contributing to activation of the catabolic cytokines. In particular, serum levels of growth hormone (GH) and insulin-like growth factor-1 (IGF-1) decline progressively during aging, and an association between reduction in the levels of these hormones and the involution of advancing age has been proposed. It is not yet known whether, in comparison with their nonfrail counterparts, frail individuals consistently manifest larger reductions in GH and IGF-1 (and other anabolic hormones). More research is needed before it will be known whether the benefits of administering GH to the frail elderly will outweigh the disadvantages. The poor appetite and weight loss that occur in many frail individuals are likely to be accompanied by a degree of visceral protein depletion (with its attendant morbidity), which can be estimated by making serial measurements of indicators of visceral protein status such as transthyretin (TTR), retinol-binding protein (RBP), and albumin. One characteristic of the frailty syndrome that distinguishes it from the effects of aging per se is the potential reversibility of many of its features. Progressive resistance training is feasible for many elderly individuals-even the oldest old-and, by increasing muscle mass and strength, can ameliorate or reverse important aspects of physical frailty. To the extent that visceral protein depletion has been caused by an inadequate intake of calories and protein, consumption of a more adequate diet can result in betterment of the frail patient's nutritional status, as determined by clinical improvement and favorable changes in TTR, RBP, and albumin.

During Depression Screening Day in Uppsala, Sweden, 127 adolescents, 23 boys and 104 girls, in the ages 13-20 years were investigated. We found that 44 (34.6%) fulfilled the criteria for a major depression according to DSM-IV criteria and 42 (40.4%) of the girls and 2 (9.5%) of the boys had an ongoing depression. All depressive symptoms, except increased appetite, were significantly more common in the depressed as compared to the non-depressed adolescents. The most common symptoms were fatigue, decreased interest and concentration difficulties. When the adolescents with major depression were compared to adults with major depression, rated by means of self-rating with the Montgomery Asberg Depression Rating Scale, depressions among adolescents and adults were very similar. However, sleep disturbances and decreased initiative were less frequent among the adolescents while decreased appetite was more common. Many of the patients with major depression found had mild symptoms but 21 (44.7%) were regarded being in need for medical treatment.

Chronic fatigue and immune dysfunction syndrome (CFIDS) is a recognized human illness with zoonotic implications that is rarely described in animals. Eight birds of prey examined between 1992 and 1995 and sharing common symptoms (asthenia, inability to fly, poor appetite and emaciation) underwent laboratory tests revealing immunodeficiency, anaemia, high creatine kinase levels and low serum magnesium levels. Diagnosis of CFIDS was based upon these features. The effectiveness of an arsenic-based medication, thiacetarsamide sodium, administered intravenously for 2-3 days at low dosages (0.1 ml/kg/day) has been demonstrated by checks carried out 10, 20 and 30 days after therapy. The symptoms and the immune and haematological dysfunctions disappeared within 2-4 weeks of treatment. In all patients, micrococcus-like organisms found adhering to the outer surface of many red blood cells, had disappeared at post-treatment controls. Two of five blood cultures were positive for Staphylococcus spp. (S. intermedius and S. xilosus). Consideration is given to the pharmacological activity of an arsenic-based drug in animal illnesses resembling CFIDS.

We present a case of small cell prostate carcinoma with hypercalcemia in a 75-year-old man. He was diagnosed as having stage T3bN1M0 adenocarcinoma of the prostate. His serum prostate-specific antigen level was reduced to below the normal range after a combination treatment of a luteinizing hormone-releasing hormone agonist and flutamide for prostate carcinoma. He subsequently experienced increasing fatigue, poor appetite, short time loss of consciousness and pain in his lower abdomen. His serum calcium level and carcinoembryonic antigen were increased. He died 5 months from the start of treatment. The autopsy revealed small cell carcinoma of the prostate and multiple metastasis of the lung, liver, pancreas, lymph nodes and spine.
