A randomized, double-blind, crossover comparison of risperidone and haloperidol in Korean dementia patients with behavioral disturbances.

OBJECTIVE: Behavioral disturbances in dementia are extremely prominent and distressful, and often result in serious physical, social, and economic consequences. The authors compared the efficacy and tolerability of risperidone and haloperidol in the treatment of behavioral and psychological symptoms of dementia (BPSD) in institutionalized elderly Korean patients with Alzheimer disease, vascular dementia, or mixed dementia. METHODS: This was an 18-week double-blind, crossover study involving 120 patients who were randomly assigned to receive flexible doses (0.5-1.5 mg/day) of risperidone or haloperidol. BPSD were assessed using the Korean version of the Behavioral Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD-K), the Korean version of the Cohen-Mansfield Agitation Inventory (CMAI-K), and the Clinical Global Impression of Change scale (CGI-C). Safety and tolerability assessments included the Extrapyramidal Symptom Rating Scale and the incidence of adverse events. RESULTS: Both risperidone and haloperidol were efficacious in alleviating BPSD. However, when receiving risperidone, patients showed significantly greater improvement than when receiving haloperidol in the total and subscale scores of the BEHAVE-AD-K, the total and subscale scores of the CMAI-K, and the scores on the CGI-C scale. Also, risperidone had an additional benefit on aggressiveness and anxieties/phobias. The risk of antipsychotic-induced parkinsonism throughout this study was significantly lower with risperidone than with haloperidol. CONCLUSION: Risperidone had a favorable efficacy and tolerability profile compared with haloperidol in the treatment of BPSD in this patient population.     

Treatment of severe subglottic laryngotracheal stenosis using hyoid graft with sternohyoid muscle flap]

OBJECTIVE: To evaluate the possibility and reliability of the hyoid-sternohyoid graft transfer in the correction of server subglottic laryngotracheal stenosis, and delineate the operation skills and clinical results. METHODS: Seven patients with severe subglottic stenosis underwent laryngotracheal reconstruction using the hyoid grafts with sternohyoid muscle flaps (HG-SHMF). Five of these patients had traumatic subglottic stenosis, one with scar tissue of unknown etiology arising in the subglottic region, another with tracheal narrowing caused by inhalation of hydrochloric acid. RESULTS: All seven patients were successfully decannulated with moderate good voice. The average time from reconstruction to decannulation was 15.4 months. The stent was endoscopically removed with a range of 3 to 22 months; the mean time required for stenting was 9.6 months. Two patients who received additional salvage reconstruction procedures because of graft or stent displacement were extubated with improved voices and satisfactory airway. CONCLUSIONS: The HG-SHMF transfer was a single-stage reconstruction, relatively simple procedure that can restore an adequate airway and a good voice. Patients undergoing laryngotracheal reconstruction with HG-SHMF must have regular, long-term follow-up since graft displacement and recurrent granulation tissue or scar reformation can cause restenosis after an initially successful surgery. This procedure should be used in a large number of patients to further test its reliability.

Acupuncture Treatment of Frequent Urination

Patient Liu （a male office worker of a company in Beijing）, aged 49, paid his first visit on March 10, 2003, with the chief complaint of frequent urination at night for over one year. One year ago, he started to have frequent urination 4-5 times every night, which disturbed his sleep and made him fatigue during the day. Though he tried to drink less water, the above symptoms couldn＇t be alleviated. The condition was accompanied by such symptoms as listlessness, general lassitude,     

The witches’ brew of spirituality and medicine

Recent proposals to join spirituality and medicine are facile and ill defined. The notion that physicians have the time or training to make assessments and recommendations about spirituality is misguided. Whenever a physician demonstrates personal caring for a patient, the healing process is likely enhanced, and in that sense, physicians often promote the spirituality of the patient. However, recent proposals to extend the physician’s task to that of assessing religion and directing the patient toward approved forms of spirituality are inappropriate. The languages of religion and science are radically different. The cultural body-mind split will not be solved by such simplistic solutions as having physicians endorse spirituality, which will result only in denigration of both medicine and religion. Physicians are encouraged to rely on clinically trained ministers for assistance in understanding the patient’s state of mind or spirit and its possible effects on the course of illness and health.
