There has been intense controversy about postconcussion syndrome (PCS) since Erichsen’s publication in 1866 on railway brain
and spine. Headache as a result of trauma is one of the most common secondary headache types. Posttraumatic headache (PTH)
remains a very controversial disorder, particularly with relation to chronic PTH following mild closed-head injury. PTH is
one of several symptoms of PCS, and therefore may be accompanied by additional cognitive, behavioral, and somatic problems.
PTH also is an important public health issue due to its associated disability and often refractory clinical course. While
current awareness of PTH has become more prominent due to increased scrutiny given to both combat-related and sports-related
head injuries, directed treatment remains a difficult challenge for physicians. Because of the frequently associated medicolegal
aspects, PTH is one of physicians’ least favorite types to treat. The article reviews both PCS and PTH. 相似文献

Personality, attitude, and hallucinogenic drug use data were obtained from 298 male and female adult members of labor unions. Multiple regression and canonical correlation analyses of drug use, personality, and attitude data revealed that: the use of hallucinogens was significantly related to needs for novel or unconventional experiences and negative attitudes toward conventionally defined social values, and marijuana use scores were more strongly associated with the set of predictor variables than were other drugs reported. 相似文献

Nursing homes are becoming increasingly involved with medical education, and the Veterans Administration (VA) has been particularly active in this movement. We conducted a system-wide survey of VA nursing home facilities to determine the degree to which they participate in medical and other professional training and the features associated with such training. Of the 116 VA nursing homes in 1987, 113 (97.4%) returned completed questionnaires. Compared to "standard" VA facilities (n = 85), "teaching" nursing homes (n = 28)--those in which physicians received at least 20 hours of training per capita annually--were significantly larger, admitted and discharged significantly more patients per occupied bed, and placed a significantly larger proportion of discharged patients in noninstitutional community settings. Care costs in the teaching nursing homes were slightly but not significantly higher, despite significant increases in levels of professional staffing and amounts of training activities in all disciplines. During the survey year, teaching nursing homes provided training experiences for 440 students, residents, and fellows in internal and rehabilitation medicine, as well as for 2,700 other health professionals. The growth of teaching nursing homes in the VA system appears to be associated with positive changes in the pattern of health-care delivery, and it is increasing the number of health-care professionals trained in long-term care. 相似文献
