Regional differences in bone density of young men involved in different exercises.

In this cross-sectional, retrospective study, the bone mineral content (BMC) and density (BMD) of the whole skeleton, upper limbs, lower limbs, femoral neck, and lumbar vertebrae were measured using dual photon absorptiometry and the results compared in healthy young males involved in: weight-lifting, running, cross-training, or recreational exercises. When adjusted for body weight, the upper limb BMD was highest in those engaged solely in weight-lifting (mean 1.021, SE 0.019, and 95% CI 0.981-1.061) and lowest in runners (mean 0.908, SE 0.019 and 95% CI 0.869-0.946). These differences were significant (P = 0.0004). There were no significant differences in upper limb BMD between weight-lifters and cross-trained athletes and between runners and those engaged in recreational exercises. Significant differences in BMD were observed between weight-lifters and recreational athletes (P = 0.001) and between cross-trained athletes and runners (P = 0.03). No other significant differences were observed. These data suggest that healthy, young, adult males reporting a history of intensive weight-lifting had significantly greater bone mass of the upper limb bones than those reporting a history of non-weight-lifting exercises. These results imply a specific versus generalized effect of mechanical load on bones of the skeleton.

NANDROLONE DECANOATE FOR MEN WITH OSTEOPOROSIS

To compare the efficacy and safety of nandrolone decanoate and calcium (NDC) with those of calcium alone (CAL) in men with idiopathic osteoporosis, a 12-month, randomized, prospective, controlled study, was performed in an outpatient clinic. Twenty-one men with idiopathic osteoporosis (as determined by radiological and dual energy x-ray absorptiometry findings) were randomly allocated to either 50 mg nandrolone decanoate intramuscularly (im) weekly and 1,000 mg oral calcium carbonate daily (NDC group) or to 1,000 mg oral calcium carbonate daily (CAL group). Bone densitometry (total body, left femur, and lumbar spine), serum, and urine biochemical parameters were measured at 3-month intervals. In the NDC group, bone mineral density initially increased, reached a plateau, and then decreased to near baseline levels at 12 months. Increases in lean muscle mass mirrored these changes. Free and total testosterone significantly decreased. Hemoglobin increased in all patients in this group. Patients in the CAL group exhibited no significant change in either total body or bone mineral density or biochemical parameters. Thus, nandrolone decanoate, 50 mg im weekly, transiently increases the bone mass of men with idiopathic osteoporosis in this preliminary study. Careful monitoring is necessary.

Insomnia and Mild Cognitive Impairment

Insomnia is a common problem in older people, especially in patients with mild cognitive impairment (MCI) whose circadian rhythm is often compromised. Insomnia exerts such a toll on caregivers that it is frequently the primary reason for seeking to institutionalize their loved ones. Three different types of insomnia are recognized: sleep-onset or initial insomnia, sleep maintenance or middle insomnia, and early morning awakening or late insomnia. Nocturnal hypoglycemia, as a cause of middle insomnia, is the main focus of this case study. Other types of insomnia are also briefly reviewed. The management of insomnia is then discussed including sleep hygiene, the usefulness and potential drawbacks of dietary supplements, nonprescription over-the-counter preparations and prescription hypnotics. Sleep architecture is then briefly reviewed, emphasizing the importance of its integrity and the role of each sleep stage.

Visual Hallucinations and Paranoid Delusions

Visual well-formed hallucinations, fluctuations in the level of cognition, and alertness and extrapyramidal signs are core features of dementia with Lewy bodies. Some patients realize that what they are seeing or hearing are just hallucinations and learn to accept them. Others, however experience these hallucinations as quite real and cannot be dissuaded from the firm belief that they are. In fact, efforts to dissuade them often serve only to confirm the often associated paranoid delusions and this may lead to a catastrophic ending. Hence, it is best not to contradict the patient. Instead, attempts should be made to distract the patient and change the focus of her or his attention. In this case scenario, we present a 68-year-old man who has been diagnosed with dementia with Lewy bodies. He lives with his daughter. He has visual hallucinations and paranoid delusions that worsen at night: He thinks there are people outside the house plotting to kill him. We discuss what went wrong in the patient/caregiver interaction and how the catastrophic ending could have been avoided or averted.

Repetitive Questioning Exasperates Caregivers

Repetitive questioning is due to an impaired episodic memory and is a frequent, often presenting, problem in patients with Alzheimer’s disease (amnestic type). It is due to the patients’ difficulties learning new information, retaining it, and recalling it, and is often aggravated by a poor attention span and easy distractibility. A number of factors may trigger and maintain repetitive questioning. Caregivers should try to identify and address these triggers. In the case discussion presented, it is due to the patient’s concerns about her and her family’s safety triggered by watching a particularly violent movie aired on TV. What went wrong in the patient/caregiver interaction and how it could have been avoided or averted are explored. Also reviewed are the impact of repetitive questioning, the challenges it raises for caregivers, and some effective intervention strategies that may be useful to diffuse the angst that caregivers experience with repetitive questioning.

Repetitive Questioning II

Repetitive questioning is a major problem for caregivers, particularly taxing if they are unable to recognize and understand the reasons why their loved one keeps asking the same question over and over again. Caregivers may be tempted to believe that the patient does not even try to remember the answer given or is just getting obnoxious. This is incorrect. Repetitive questioning is due to the underlying disease: The patient’s short term memory is impaired and he is unable to register, encode, retain and retrieve the answer. If he is concerned about a particular topic, he will keep asking the same question over and over again. To the patient each time she asks the question, it is as if she asked it for the first time. Just answering repetitive questioning by providing repeatedly the same answer is not sufficient. Caregivers should try to identify the underlying cause for this repetitive questioning. In an earlier case study, the patient was concerned about her and her family’s safety and kept asking whether the doors are locked. In this present case study, the patient does not know how to handle the awkward situation he finds himself in. He just does not know what to do. He is not able to adjust to the new unexpected situation. So he repeatedly wants to reassure himself that he is not intruding by asking the same question over and over again. We discuss how the patient’s son-in-law could have avoided this situation and averted the catastrophic ending.

Agnosia Interferes With Daily Hygiene in Patients With Dementia

Patients with dementia, particularly Alzheimer’s disease, may not recognize that their clothes are dirty. They may see the food stains and discoloration of the clothes and yet because of their agnosia are unable to integrate these observations and deduce that their clothes are dirty and need to be changed. They will, therefore, resist attempts to get them to change clothes, especially if these clothes happen to be their favorite ones. This often causes caregivers to become frustrated, especially, if it represents a change in the patient’s previous habits of only wearing clean clothes. In this case study, we present a 72-year-old woman with moderate Alzheimer’s disease who lives with her daughter, who adamantly refuses to change the clothes she has been wearing for a few days and which are now clearly dirty. We report the interaction, highlight what went wrong in the patient–daughter interaction, and discuss how the catastrophic ending could have been avoided or averted.

Driving and Patients With Dementia

Driving is a symbol of autonomy and independence, eagerly awaited during adolescence, cherished during adulthood and reluctantly rescinded during old age. It is nevertheless an individual’s privilege, not right, especially as driving may affect other drivers and pedestrians on the road. It is therefore not only the individual patient who is at stake but essentially the entire community. In this case scenario, we describe the situation that arose when a patient with multi-infarct dementia wanted to go for a drive and his son and grandson tried to convince him that he could no longer drive. What went wrong in the caregivers/patient interaction is presented. The futility of arguing with patients who have dementia is highlighted as well as the suspiciousness it may generate. Alternate actions that can be useful to avoid/avert the situation from escalating and having a catastrophic ending are discussed. Testing/evaluating patients with dementia for fitness to drive is also reviewed and a list of select resources is included.

Impulsive, Disinhibited Behavior—Dining in a Restaurant:

Dining in a restaurant with a loved one who has dementia can be an ordeal, especially if the expectations of the caregiver do not match those of the patient and the restaurant environment is not suitable for patients with dementia. The size of the dining area, lighting, background music or noise, décor of the room, number of customers, variety of the items on the menu, number of plates and cutlery on the table, in addition to flowers, candles, and other decorations on the table are all potent distractors. There are so many stimuli; the patient can be overwhelmed with information overload and not able to focus on the main purpose of the event: have dinner and especially enjoy the other person’s company. In this case scenario, we present a 62-year-old man diagnosed with behavioral variant frontotemporal dementia (bvFTD). His daughter “invited” him to have dinner with her at a very fancy restaurant to celebrate her promotion at work. Unfortunately, whereas the evening started very well, it had a catastrophic ending. We discuss what went wrong in the patient/daughter interaction and how the catastrophic ending could have been avoided or averted.

Fronto-Temporal Dementia, Diabetes Mellitus and Excessive Eating:

Diabetes mellitus is common among older people. Hypoglycemia is a sign of poorly controlled diabetes mellitus and may lead to irritability, agitation, anxiety, hunger, and an excessive food intake, which in turn may make the control of diabetes more difficult. Excessive, inappropriate food intake is also a sign of Fronto-Temporal Dementia (behavioral variant: bvFTD). In this case study, we describe the events leading to an altercation that developed between an older diabetic patient with bvFTD and the staff in an Assisted Living Facility. His first dose of insulin was given early that morning while he was still asleep. He, subsequently, woke up feeling hungry, agitated, and irritable. This, in turn, exacerbated the hyperorality associated with bvFTD. We examine what went wrong in the patient/caregiver interaction and how this potentially catastrophic situation could have been avoided or defused.
