A confederate civilian physician shot and killed a white Union officer who was drilling Negro troops in Norfolk, Virginia. With no question as to guilt, President Abraham Lincoln decided to have a medical expert conduct a professional sanity/insanity examination. Documentation indicates that legal and political factors may have influenced Lincoln's decision. As a lawyer, Lincoln prosecuted a case where the insanity plea was used as a defense. Two influential Cabinet members, William H. Seward and Edwin M. Stanton, also had legal experience involving the insanity plea. Politically, Lincoln faced serious issues such as the draft riots, the military necessity to recruit slaves into the army, the impact of Union Negro soldiers upon the border states, the morale and discipline of the army and the upcoming presidential election. Upon Seward's recommendation, Lincoln chose a physician who had a reputation for finding the accused sane and who did so in this case. As the southern physician was hanged, Lincoln's means achieved the desired legal and political ends.Partial research support from a Continuing Faculty Development Award from the New York State/United University Professions Professional Development and Quality of Working Life Committee.

A fatal case of strychnine intoxication is reported. The patient expired despite early aggressive management and prevention of metabolic complications. Serial blood levels are reported. In contrast to a previous report describing first order elimination kinetics, our data suggest that strychnine follows Michaelis-Menton elimination kinetics. The case illustrates the rapid, dramatic course of severe strychnine ingestions. A review of the toxicokinetics, mechanism of action and treatment of strychnine intoxication follows. 相似文献

A great deal is now known about the mechanisms of conditioned fear acquisition and expression. More recently, the mechanisms
of inhibition of conditioned fear have become the subject of intensive study. The major model system for the study of fear
inhibition in the laboratory is extinction, in which a previously fear conditioned organism is exposed repeatedly to the fear-eliciting
cue in the absence of any aversive event and the fear conditioned response declines. It is well established that extinction
is a form of new learning as opposed to forgetting or “unlearning” of conditioned fear, and it is hypothesized that extinction
develops when sensory pathways conveying sensory information to the amygdala come to engage GABAergic interneurons through
forms of experience-dependent plasticity such as long-term potentiation. Several laboratories currently are investigating
methods of facilitating fear extinction in animals with the hope that such treatments might ultimately prove to be useful
in facilitating exposure-based therapy for anxiety disorders in clinical populations. This review discusses the advances that
have been made in this field and presents the findings of the first major clinical study to examine the therapeutic utility
of a drug that facilitates extinction in animals. It is concluded that extinction is an excellent model system for the study
of fear inhibition and an indispensable tool for the screening of putative pharmacotherapies for clinical use. 相似文献

Medical complications of prematurity 总被引:4,自引:0,他引:4
The improved survival of extremely premature infants has generated intense interest in the quality of life of the survivors. This review focuses on the major long-term complications of prematurity (developmental disability, retinopathy of prematurity, chronic lung disease) and concludes with an overview of the broader spectrum of morbidity. Severe impairment (cerebral palsy, mental retardation, retrolental fibroplasia, severe chronic lung disease) fortunately occurs in a small proportion of survivors. However, the prevalence of the lesser morbidities (minimal cerebral dysfunction/learning disability, poor growth, postneonatal illnesses, rehospitalization) is less clearly defined. These problems all have an impact on families, and on medical and educational services. 相似文献

Monoclonal antibodies to intermediate filament proteins: Diagnostic specificity in orbital pathology
Thomas D. Lindquist M.D. Ph.D. James C. Orcutt M.D. Ph.D. Allen M. Gown M.D. 《Survey of ophthalmology》1988,32(6):421-426
Intermediate filaments derived from different cell types are antigenically distinct. Monoclonal antibodies to human intermediate filament proteins can, therefore, be used as tissue-specific reagents capable of distinguishing cell type in poorly differentiated neoplasms. We report a case demonstrating the specificity of antiintermediate filament protein antibodies in establishing a difficult orbital diagnosis of esthesioneuroblastoma. 相似文献

PURPOSE: This articles explores cultural perceptions and values related to brain death and organ donation from both a Western and non-Western perspective. SOURCE: Anthropological literature review of the historical concept of brain death in Canada using Eastern culture as a comparison. Principal findings: Although the concept of brain death and concomitant organ donation have become widely practiced in Western nations such as Canada, from a cross-cultural point of view these concepts and practices can be deeply troubling and may hold profoundly different meaning to people new to Canada. CONCLUSIONS: Canada has a deep commitment and obligation to respect diversity as reflected in the Canadian Charter of Rights and Freedoms. Therefore, healthcare workers have an obligation to respect cultural differences. To truly respect cultural differences we must first explore our own culturally formulated belief systems and then consider how our views may interface with other cultures. Our findings call for a greater analysis of the cultural influences on the concept of brain death and organ donation as a means of building a better understanding and respect for cultural diversity. 相似文献

BACKGROUND: Vitamin D deficiency is a putative, pathogenic cofactor in the increase in osteopenia and osteoporosis seen in patients with Crohn's disease. OBJECTIVE: To determine the frequency of low serum 25-hydroxy-vitamin D3 (25-OHD) levels and the associated alterations in bone mineral density in a cohort of adults with Crohn's disease. METHODS: 25-OHD levels were determined in 242 consecutive patients with Crohn's disease seen in two tertiary inflammatory bowel disease referral centres. Bone mineral density was assessed by dual energy x-ray absorptiometry. RESULTS: Nineteen (8%) patients exhibited vitamin D deficiency (25-OHD less than 25 nmol/L) and 52 (22%) patients exhibited vitamin D insufficiency (25-OHD less than 40 nmol/L). Mean T-scores at the lumbar spine, femoral neck, total hip and ultradistal radius in the group with low 25-OHD did not differ from those of the normal 25-OHD group. Serum alkaline phosphatase and parathyroid hormone levels were higher in the low 25-OHD group than in the normal group. Decreased red blood cell (RBC) folate predicted low 25-OHD in male patients, while smoking, RBC folate and serum iron predicted low 25-OHD in female patients. The rate of low 25-OHD deficiency in the winter was significantly higher than that in the summer (11.9% versus 2.8%, respectively). CONCLUSION: Vitamin D-deficient Crohn's disease patients exhibit biochemical evidence of metabolic bone disease, without detectable differences in bone mineral density. Sunlight exposure, nutrition and smoking status were predictors of vitamin D deficiency in this patient cohort. 相似文献
