A prognostic model for head injury.

A prognostic model for head injured patients was developed. Patients fall into one of four prognostic categories at the end of the first hospital day: I. Discharge alive on or before the seventh hospital day. II. Discharge alive 8--42 days after admission. III. Discharge alive after 42 days, or dead after five years. IV. Discharge dead before five years. The outcome of 63% of the patients was predicted correctly. The model correctly placed, or missed by only one category, 97% of the patients observed. Errors tended to the optimistic side of observed outcomes. Age and pattern of consciousness were critical prognostic factors.

Penis envy: from childhood wish to developmental metaphor.

Two phases of penis envy are considered. The first regularly occurs early in development and is registered as a narcissistic injury which can be resolved under optimal conditions and can contribute to female psychosexual development. If, however, it is not favorably resolved or, even more significantly, if the basic character disorder is of a narcissistic type, the awareness of the genital difference becomes one of many narcissistic traumas. A later phase of penis envy usually represents a regressive effort to resolve oedipal conflicts. In the past, these two phase-oriented forms of penis envy have not been adequately distinguished. Two clinical examples are presented in which the envy of men was only part of a tendency to envy in a narcissistic character disorder. In the analysis, the interpretation of the penis envy offered a metaphor around which all of the "free-floating" envy could coalesce. The cases illustrate the necessity to consider penis envy as the manifest content of a symptom that needs analysis, rather than as "bedrock" or ultimate conflict.

Assessment of pulmonary and intrathymic hemosiderin deposition in sudden infant death syndrome.

The aim of this study was to stain lung and thymus gland sections that had been taken from infants who had died of sudden infant death syndrome (SIDS) for interstitial hemosiderin and to compare the results with those obtained for controls. There were two groups of SIDS infants, one with, and a second group without, histories of apparent life-threatening events (ALTEs). No significant difference in numbers of cases with interstitial hemosiderin deposition was found between SIDS infants with histories of ALTEs (n = 4 of 12, 33.3%), SIDS infants without histories of ALTEs (n = 4 of 22, 18.2%), and controls (n = 4 of 24, 16.7%). However, if four of the control cases with histories of previous chest trauma were excluded, there was a significantly greater number of cases with pulmonary interstitial hemosiderin in the SIDS infants with histories of ALTEs compared with the subgroup of control infants with no previous chest trauma (n = 1 of 20, 5%) (P < .05). No relationship could be established between the timing of the ALTEs, the type of resuscitation or age of the infant at death, and the presence of hemosiderin. None of the sections of thymus gland stained positively for hemosiderin. Positive staining for pulmonary interstitial hemosiderin, therefore, differentiated a group of SIDS infants with histories of previous ALTEs from a subgroup of control infants with no histories of previous chest trauma. However, pulmonary interstitial hemosiderin staining could not be used with certainly to confirm or exclude previous ALTEs in individual SIDS cases as not every SIDS case with a history of an ALTE stained for pulmonary interstitial hemosiderin. In addition, positive staining occurred for SIDS infants without histories of ALTEs and also for control infants who died of other causes.
