Complete abortion of early ectopic pregnancy.

Abortion of an early ectopic pregnancy is a rarely diagnosed event. Coincidental serial hormonal studies performed on a patient suffering from idiopathic secondary infertility enabled the authors to record plasma estradiol, progesterone and beta-human chorionic gonadotropin concentrations, which, combined with the physical findings, ultrasonography and laparoscopy, led to the diagnosis of a complete abortion of an early ectopic pregnancy. Apart from slight vaginal bleeding on day 44 of a prolonged cycle, the patient was asymptomatic throughout and the importance of plasma beta-human chorionic gonadotropin determination in such a situation is discussed.

Neonatal herpesvirus sepsis following internal monitoring.

The use of internal monitoring, in which an electrode is attached to the fetal scalp, may be associated with serious complications. The authors present a case of fetal neonatal sepsis due to herpesvirus arising at the electrode site.

Psychiatric consultation for competency to refuse medical treatment. A retrospective study of patient characteristics and outcome.

Forty-one psychiatric consultations on medical-surgical inpatients for competency to refuse medical treatment were studied retrospectively. The competent (n = 16) and incompetent (n = 25) patients were compared in terms of demographic data, diagnoses, clinical variables, details about treatment refusal, and outcome following competency assessment. The incompetent patients tended to be men, the focus of more urgent requests, and to have refused operations. The incompetent patients tended to have organic brain syndromes; the competent patients had personality disorders, adjustment disorders, or no psychiatric diagnosis. Ultimate acceptance of treatment initially refused was common in both groups; differential psychiatric interventions were recommended. The process of psychiatric consultation appeared to facilitate acceptance of treatment initially refused.

Memory and mental status correlates of modified Braak staging.

We assessed the relationships of performance on memory and mental status tests and neuropathologic stage of Alzheimer's disease as defined by Braak and Braak in 29 patients from a prospective clinicopathologic series. We predicted that memory changes would occur at an earlier Braak stage than mental status changes. Staging was accomplished by matching the topographic distribution of neurofibrillary lesions detected with tau immunocytochemistry to the best fitting diagram published by Braak and Braak. Higher Braak stages were associated with decrements in performance on both memory and mental status tests. As predicted, memory performance declined from stages II to III and mental status did not decline until stages III to IV. The association between memory and Braak stage was unchanged after adjusting for neocortical senile plaques, whereas adjustments for Braak stage eliminated the association between cognitive functioning and amyloid burden. We conclude that Braak staging provides a useful summary of Alzheimer's disease neuropathology, which is associated with both memory and mental status performance.
