    Notes: Summary For unknown reasons, there is a greater increase in the risk for cardiovascular complications in diabetic women than in diabetic men. Our aim was to study gender-related differences in the mechanical properties of the great arteries in patients with insulin-dependent diabetes mellitus (IDDM) but free from known cardiovascular and cerebrovascular complications. We measured arterial stiffness (Β, inversely related to arterial compliance) in the abdominal aorta and the common carotid artery non-invasively using echo-tracking sonography in 30 women (mean age 34 years, range 20–61) and 26 men (mean age 38 years, range 22–56) with IDDM. The results were compared with those of healthy individuals of corresponding age and gender. The results showed a marked gender-difference in changes of arterial stiffness. Arterial stiffness was increased in both the abdominal aorta and the common carotid artery in diabetic women compared to control women (p=0.0001 and p=0.0076, respectively). In contrast, there was no significant difference in stiffness of the abdominal aorta or the common carotid artery between the diabetic men and the control men (p=0.69 and p=0.39, respectively). In conclusion, this study has shown that stiffness of the aorta and the common carotid artery is increased in diabetic women but not in diabetic men. Increased arterial stiffness in diabetic women may be a pathogenic factor which could help to explain the gender-related differences in the risk for cardiovascular and cerebrovascular complications in diabetic subjects.

    Notes: Summary This study reports on clinical outcome in 38 patients with severe head injuries (posttraumatic coma for 6 hours or more) treated with barbiturate coma because of intracranial hypertension. Eighteen patients died, 4 patients remained in a severely disabled or a chronic vegetative state, and 16 patients reached the levels good recovery/ moderate disability. Six of these patients returned to work or school full time, 4 for half time and 3 were in a rehabilitation program. Fourteen patients were subjected to a comprehensive neuropsychological assessment. All patients except one exhibited varying degrees of cognitive dysfunction and 6 patients had signs of personality change. The quality of life for the majority of surviving patients was relatively good but the positive effects of barbiturate coma therapy in the age groups over 40 years appeared to be limited.

    Notes: The present investigation was concerned with the effect of the progestogen hormone, DuphastonR, on the inflammatory reaction of rats. The granuloma pouch technique elaborated by Selye was used. The injection of 25 ml of air into the dorsum of the rat created a subcutaneous sac, into which the hormone and the irritant were deposited. Injections of 1 % solution of croton oil (the irritant) into this sac produced a pronounced inflammatory reaction in the connective tissue of the wall of the sac and formed a thick granulomatous membrane. If the progestogen was deposited into the granuloma pouch at the same time as the eroton oil or on the previous day, the membrane, compared with that induced solely by the croton oil was much thinner. Progestogen itself injected into the air sac produced no granulomatous membrane at all.These results seem to indicate that the hormone progestogen may depress the inflammatory reaction of the connective tissue induced by the croton oil. In current experiments the effect of estradiol, gonadotropin and relaxin on the granuloma pouch inflammation is being studied.

    Notes: Summary Fifteen patients with a good neurological outcome after aneurysmal SAH and surgery were collected prospectively. Six months after surgery neurological examination and a SPECT study for evaluation of the three dimensional CBF distribution as well as an extensive neuropsychological test were performed. In all patients with pathological SPECT findings the location of the reduced regional CBF correlated with the location of the ruptured aneurysm and/or side of surgical approach. The volume of the brain tissue with reduced rCBF showed a great variety, from 9–112 cm3 (mean: 33 cm3). Similarly, the maximum flow reduction in the affected areas also varied considerably from 17–95% (mean: 39%). In general, the neuropsychological functioning of the patients post SAH was favourable. Seven individuals had a presumably normal neuropsychological appearance with respect to estimates of premorbid levels of functioning. Another four patients were slightly impaired and the remaining four were moderately affected. Only in five cases did the location of SPECT pathology and the site of neuropsychological impairment appear to coincide, whereas this was not the case in the remaining 10 patients. In general, the extent of SPECT pathology did not differ in the three neuropsychological outcome groups (normal, slight and moderate disability).
