Bone loss at the distal femur and proximal tibia in persons with spinal cord injury: imaging approaches, risk of fracture, and potential treatment options.

Persons with spinal cord injury (SCI) undergo immediate unloading of the skeleton and, as a result, have severe bone loss below the level of lesion associated with increased risk of long-bone fractures. The pattern of bone loss in individuals with SCI differs from other forms of secondary osteoporosis because the skeleton above the level of lesion remains unaffected, while marked bone loss occurs in the regions of neurological impairment. Striking demineralization of the trabecular epiphyses of the distal femur (supracondylar) and proximal tibia occurs, with the knee region being highly vulnerable to fracture because many accidents occur while sitting in a wheelchair, making the knee region the first point of contact to any applied force. To quantify bone mineral density (BMD) at the knee, dual energy x-ray absorptiometry (DXA) and/or computed tomography (CT) bone densitometry are routinely employed in the clinical and research settings. A detailed review of imaging methods to acquire and quantify BMD at the distal femur and proximal tibia has not been performed to date but, if available, would serve as a reference for clinicians and researchers. This article will discuss the risk of fracture at the knee in persons with SCI, imaging methods to acquire and quantify BMD at the distal femur and proximal tibia, and treatment options available for prophylaxis against or reversal of osteoporosis in individuals with SCI.

[Animal-assisted therapy for people suffering from severe dementia]. / Le soutien psychologique assisté par l'animal à des personnes atteintes de pathologies démentielles sévères.

INTRODUCTION: The elderly represent the fastest growing population group in France. The care management of people suffering from dementia has become an important problem. Demented patients manifest behavioral problems, depression, apathy, impairment in social activities and language skill disorders. The literature contains few studies investigating animal-assisted therapy for demented patients. However, there is a clear need for psychological assistance for this population. In the management of such behavioural problems associated with dementia, we propose to develop a dog-assisted therapy. Three qualitative case studies are analysed to specify the perceptions of the therapist regarding animal-assisted therapy. SUBJECTS AND METHODOLOGY: This study is a qualitative pilot study. Subjects were two female and one male patients admitted in a nursing home. They were diagnosed with severe dementia. Their mean age was 94 years. All of them agreed to attend the dog therapy activities and informed consent from their family was requested. We met these patients 15 times over nine months. The meetings always took place in the same place for 30 min, once a week. The evaluation was based on the clinical observations of the psychologist. RESULTS: This study revealed many psychological benefits for patients with dementia. The animal-assisted therapy had a calming effect on the patients. It could well be helpful as a communication link during therapy sessions. The dog, because of its unconditional acceptance, increases the self-esteem of the patient and contributes to a more secure environment. The patients, who rarely interacted socially, increased their interactions with the dog. In spite of the lack of normal verbal use of language, nonverbal communication continues including touching and posture. Furthermore, patients verbalized that the dog was affectionate and they could identify themselves with it. CONCLUSIONS: This prospective study leads up to the conclusion that pet therapy could prove to be efficient. We conducted animal-assisted therapy sessions for patients with severe dementia and found that psychological assistance could be flexible enough, to meet the special needs of institutionalized persons suffering from dementia. The pet therapy programs may provide help for many patients, but the framework and conditions of this practice should be clearly defined, until the dog itself, can become the therapist.

[How can psychological help be provided for the patient/caregiver tandem home?]. / Pour un soutien pychothérapique à domicile du couple patient/aidant.

INTRODUCTION: Elderly people and their family helpers are often isolated at home and do not have access to the professional psychological help that they require. For an elderly population, the trips to consulting rooms are difficult, tedious and expensive. Besides, maintaining a patient at home is heavy to manage for close relatives because of the organization, financial issues and above all the risk of psychological burnout. The literature shows us that psychological assistance is more common at distance from home, in hospitals, in special institutions or specific organizations. However, there is a clear need of help at home. We propose to develop psychological assistance at home for the patient/helper tandem in cases of dementia. This prospective study reports three different cases. METHOD: This study is a qualitative pilot study. Participants characteristics: patients were diagnosed with severe dementia, assistance showed deep fatigue of the helper, both members of the tandem lived at home, age above 69 years, the eed for nursing care at home. THERAPEUTIC ASSESSMENT: The psychological clinician acts after proposing his helpand not on a clear request from the patient. He will meet his patient 7 times during 4 months. The meetings always take place in the same place and last 45 minutes. Confidentiality during the meeting is explained and guaranteed so the patient can speak openly. EVALUATION: An independent psychologist assessed the monitoring in the hospital. Our methodology included two assessments: the first, assessing the task of the helper before the evaluation and the second taking into account a new measurent of the task and the opinions of the participants following a semi-directed interview. The evaluation of the task was performed using Zarit's scale. The evaluation was also based on the clinical observation of the psychologist. RESULTS: Organization of the monitoring: one meeting per week was sufficient for all participants with a minimal duration of 45 minutes. The fact that the meetingsrook place at home was appreciated, because of their simple and convenient organization. The patient/helper tandems in those suffering from advanced dementia could only have taken place in the home because transport any where else would have beent too difficult for them. The sessions during this research study were free of charge. Two out of three participants were ready to pay so long as the study could continue. The managers were bothered a few times by phone calls and/or unexpected visits, invitations for a cup of tea and requests for a small service (like mailing a letter). Assistance for the caregiver: all the caregivers declared that assistance was a personal improvement in a period of doubt, loss of self-confidence and isolation. Furthermore, clinical observation of the therapeutic assistance appears to show that psychological help at home could lead to the improved psychological function of the helper. This was emphasized when we established the limits of the caregiver/patient relationship. We observed a better balance in the input of investing and de-investing and better acceptance of the identity modifications which were required for the caregiver. Assistance for the patient: we believe that this sort of intervention has positive effects on the patients themselves. This care at home protects the destructurated identity of the patients and their intimity. Moreover, intrapsychic tension can be lowered by being shared with the psychologist. Assessment of the burden: among the three patients who wete studied, the burden was unaltered in one case (43/88; 43/88), significantly improved in one case (41/88; 24/88) and remained light in one case (18/88; 16/88). DISCUSSION: We discovered that Zarit's test showed some limits. The time to complete the test is quite long and tedious for caregivers. Some questions are too direct and can put the caregivers in a guilty position. The mini Zarit version with only seven items, appears more satisfactory because it's shorter and provokes less guilt. The other point concerns the therapeutic frame at home. The usually represents all the constants of the therapeutic process including the role of the psychologist and all the items that refer to space, time, management of the timetable, payement and interruptions in care. Could the fact of being at home be harmful for the therapeutic process? Of course, the place of residence is less neutral than a office in an institution and the superposition of the frame of life and of the therapeutic frame raises lots of questions for the psychologist: entering a private house is like entering a private life, which is not without consequences on the follow-up. We are here far from a classical frame of therapeutic interviews, so the frame must be clearly defined. CONCLUSION: This prospective study leads us to the conclusion that the superposition of the frame of life and of the therapeutic frame represents a limit to psychotherapy but is not exclusive of psychological support at home. As a supplement to this face to face follow up at home, we could imagine other ways of providing such psychological support, by phone or by telemedicine for instance. Could the new technologies of communication help to compensate the lack of means in favour of the caregivers at home? Although these new technologies are more dedicated to institutions than to providing care at home, could they not be helpful for organizing psychological help at home? However, in order to validate such devices, they need to be fried and assessed at home.

[Combined therapies in family practice and hospitals. A controlled clinical study of a population of 162 patients with criteria of age-related memory disorders]. / Thérapies combinées en médecine praticienne et hospitalière. Etude clinique contrôlée d'une population de 162 sujets répondant aux critères des troubles de la mémoire liés à l'âge (AAMI).

OBJECTIVES: To assess the combination of drug and cognitive therapy on age-associated memory impairment (AAMI). PATIENTS AND METHODS: A double-blind randomized trial was performed involving 162 patients with age-associated memory impairment selected and followed by their general practitioners. Two intervention methods-a drug and a cognitive therapy-were assessed in combination. Three randomized parallel groups of 54 patients each, aged 55 years and over, were followed and treated for 3 months. After a placebo washout period of 10 days, one group received 2.4 g of piracetam, another group, 4.8 g and the third, a placebo. RESULTS: A total of 135 patients, 45 in each group, completed the study. Combined therapy was most effective in patients whose baseline performance on memory tests was lowest. The best results were observed with piracetam combined with memory training. This result confirmed by the global impression of the principal investigator was in agreement with findings of previous double-blind placebo-controlled trials assessing the combined effect of drug treatment and memory training. CONCLUSION: This result confirmed by the global impression of the principal investigator was in agreement with findings of previous double-blind placebo-controlled trials assessing the combined effect of drug treatment and memory training.
