We present a patient who developed a painful third nerve galsy two days after angiography had demonstrated a large aneurysm on the P1 segment of the left posterior cerebral artery. CT at this stage demonstrated extensive thrombus within the previously uncomplicated aneurysm. The haemodynamics of this aneurysm resulted in incomplete clearance of contrast medium from its fundus and we posit that this may have promoted thrombus formation. Six months later the aneurysm was shown angiographically to be completely occluded. 相似文献

Alexithymia was measured in non-treatment seeking, community-dwelling Holocaust survivors using the Toronto Alexithymia Scale—Twenty Item Version (TAS-20). Scores of survivors with (n = 30) and without (n = 26) posttraumatic stress disorder (PTSD) were compared, and associations among alexithymia, severity of trauma, and severity of PTSD symptoms were determined. Survivors with PTSD had significantly higher scores on the TAS-20 compared to survivors without PTSD. TAS-20 scores were significantly associated with severity of PTSD symptoms, but not with severity of trauma. This study adds to our knowledge of the relationship between alexithymia and trauma by demonstrating that this characteristic is related to the presence of posttraumatic symptoms and not simply exposure to trauma. 相似文献

The decrease in membrane microviscosity of erythrocyte ghosts in the
presence of clinically relevant concentrations of seven inhalation
anaesthetic agents was studied using fluorescence polarization anisotropy
of the membrane incorporated fluorescent probes 1,6-diphenyl-
1,3,5-hexatriene and 1-[4-trimethylammoniumphenyl]-6-phenyl-1,3,5-
hexatriene. All anaesthetic agents produced a dose-dependent decrease in
anisotropy of both probes, indicating decreased membrane microviscosity.
The reduction in anisotropy measured at the minimum alveolar concentration
(ED50) for anaesthesia was related inversely to the anaesthetic potency of
the agent and was directly proportional to the hypothetical concentration
of agent in the membrane calculated from lipid-water partition
coefficients. These findings do not support the hypothesis that volatile
anaesthetic agents act by increasing membrane microviscosity of the bulk
lipid bilayer to produce anaesthesia.

The application of magnetic resonance techniques in the assessment of fetal growth, fetal growth patterns and fetal health was assessed. Eighty-four sets of fetal images were obtained using a fast-scan magnetic resonance imaging technique. Measurements were made of fetal subcutaneous fat thickness, uterine cavity length and width, fetal and uterine cross-sectional areas and fetal volume. Fetal area and fetal volume measurements were found to correlate well with birth weight. Measurement of subcutaneous fat thickness may prove to be a means of differentiating between those fetuses who are constitutionally as opposed to pathologically large or small. Thirteen women had additional spectroscopic studies carried out. Twelve of the women had normal pregnancies. One woman had a twin pregnancy in which one twin died. 31P phosphorus spectra were obtained from seven of the normal pregnancies. In the remainder, the depth of the abdominal wall prevented spectra being obtained from the placenta. Differences in phosphorus metabolites were obtained from the placenta of the dead twin compared to those from the healthy pregnancies. 相似文献

The efficacy of fractionated out-patient radioiodine therapy in 38 patients with compressive symptoms due to long-standing
large multinodular goitres was assessed. The diagnosis was established by clinical assessment in addition to technetium-99m
pertechnetate thyroid scan or computed tomography scan of the thyroid and mediastinum. Oral iodine-131 therapy was administered
as a 2.22 GBq (60 mCi) cumulative dose over 4 months (555 MBq per month). All patients were monitored with serum thyroid-stimulating
hormone and free thyroxine (± free tri-iodothyronine) assays before the treatment and after each dose fraction. Clinical and
biochemical follow-up was performed on all patients and ranged from 6 to 45 months after therapy. The patients consisted of
35 female and three male patients with a median age of 59 years (range 37–87 years). Prior to treatment 20 patients were biochemically
hyperthyroid and 18 were euthyroid. Overall, 71% of patients reported a subjective improvement in compressive symptoms and
29% reported no change. Clinically assessed reduction in goitre size occurred in 92% of patients while there was no change
in 8%. At 3 months of follow-up, 31% of patients had become hypothyroid and at 18 months 66% were hypothyroid. Seven hyperthyroid
patients (35%) became euthyroid and 13 hyperthyroid patients (65%) became hypothyroid. Three patients who became hypothyroid
experienced neck soreness (transient in one patient, persistent in two patients). There were no differences in outcome between
patients who were hyperthyroid and those who were euthyroid prior to treatment. Fractionated out-patient radioiodine therapy
showed excellent short- and medium-term safety, was very well tolerated and offered a satisfactory alternative treatment to
surgery.
