- In order to compare the diagnostic ability of pulsed tissue Doppler and myocardial perfusion Single Photon Emission Computed Tomography (SPECT) in patients with a history of unstable coronary artery disease, CAD, 26 patients, 22 men and four women, age 47-76 years, were investigated in a prospective study, 5-10 day after an episode of unstable angina. Tissue Doppler and two-dimensional echocardiography were performed during dobutamine stress testing and myocardial scintigraphy after bicycle exercise and at rest. Patients with a normal SPECT had higher peak systolic velocity during dobutamine infusion, 18.9 ± 4.1 cm s-1, than patients with ischaemia, 12.2 ± 3.8 cm s-1 (P<0.001) or scar, 8.8 ± 3.0 cm s-1 (P<0.01). In a territorial analysis the difference in peak systolic velocity between areas with a normal and abnormal SPECT was less apparent. Failure to achieve ≥13 cm s-1 in mean-peak systolic velocity was the most accurate criterion for detection of significant CAD on SPECT. We conclude that pulsed tissue Doppler can be used for objective quantification of left ventricular wall motion during dobutamine stress testing and for identification of patients with CAD on SPECT but not for identification of regional ischaemia.

- In this case report we present a patient with temporal lobe epilepsy (TLE) showing partial complex seizures and secondary generalization, and treated with several antiepileptic drugs. After two consecutive seizures she had an episode of cardiac arrest followed by AV-block III which led to the implantation of a cardiac pacemaker. She subsequently received a vagal nerve stimulator because of poor response to epilepsy treatment. Combined treatment with two different electromagnetic stimulators raises the question of safety during surgery which is discussed.

- Patients operated on for complex congenital heart malformations need continuous follow-up. We present a male patient born in 1948 with Fallot's anomaly. A total correction was performed when he was 21 years old. Twenty-eight years after the operation, at routine follow-up, he presented with a significant left-to-right shunt because of a new ventricular septal defect. During the operation we found the original patch to be fractured with a central perforation. The patient received a new patch and has been without any clinical symptoms since. © 2006 by The Society of Thoracic Surgeons.

Are There Different Effects of Invasive Treatment Between Women and Men During the Acute Stage of Unstable Coronary Artery Disease?

- OBJECTIVES The FRISC II invasive trial compared an early invasive versus a noninvasive strategy concerning death and MI in CAD. This paper deals with the gender perspective in the same study.METHODS There were 749 women and 1708 men included in the study with a mean age of 66 and 64 years in women and men respectively. The patients were randomized to early invasive or noninvasive strategy and to placebo controlled long-term low molecular mass (1mm) heparin ( dalteparin) treatment for 3 months. Coronary angiographies were performed within the first seven days in 96 % and 10 % and revascularisation was performed within the first 10 days in 71 % and 9 % in the invasive and noninvasive groups, respectively.RESULTS Women were older but had less previous infarctions, better left ventricular function and less frequently had elevated troponin-levels. There were more patients with normal coronary arteries and less severe coronary artery lesions amongst the women. Accordingly, less interventions were performed in the female group although, among those who were revascularized, there was. no significant difference in the choice of procedure compared to men. There was no difference in the composite endpoint of MI and death at 12 months amongst women (12.4 vs. 10.5% in the invasive and non-invasive groups respectively) in contrast to the very favorable effect of the invasively treated group amongst the men (9.6 vs. 15.8%, p<0.001). In a multivariate interaction analysis there was different effect of early invasive strategy in the two genders (p=0.008)CONCLUSIONS Women with symptoms and/or signs of unstable coronary artery disease are older but still have less severe CAD and a better prognosis than men. In contrast to men, an early invasive strategy did not reduce the risk for future events amongst women. Further research is warranted to identify the most appropriate treatment strategy in women with unstable CAD.

- BACKGROUND: The Fragmin and fast Revascularization during InStability in Coronary artery disease (FRISC II) trial compared the effectiveness of an early invasive versus a noninvasive strategy in terms of the incidence of death and myocardial infarction (MI) in patients with unstable coronary artery disease (CAD). OBJECTIVES: In this subanalysis, we sought to evaluate gender differences in the effect of these different strategies. METHODS: The patients (749 women and 1,708 men) were randomized to early invasive or noninvasive strategies. Coronary angiography was performed within the first 7 days in 96% and 10% of the invasive and noninvasive groups, respectively, and revascularization was performed within the first 10 days in 71% and 9% of the invasive and noninvasive groups, respectively. RESULTS: Women presenting with unstable CAD were older, but fewer had previous infarctions, left ventricular dysfunction and elevated troponin T levels. Women had fewer angiographic changes. There was no difference in MI or death at 12 months among women in the invasive and noninvasive groups (12.4% vs. 10.5%, respectively), in contrast to the favorable effect in the invasively treated group of men (9.6% vs. 15.8%, p < 0.001). In an interaction analysis, there was a different effect of the early invasive strategy for the two genders (p = 0.008). CONCLUSIONS: Women with symptoms and/or signs of unstable CAD are older, but still have less severe CAD and a better prognosis compared with men. In contrast to its beneficial effect in men, an early invasive strategy did not reduce the risk of future events among women. Further research is warranted to identify the most appropriate treatment strategy in women with unstable CAD. ⌐ 2001 American College of Cardiology.

- A case of Kleine-Levin syndrome with typical periodic hypersomnia and bulemia was diagnosed. On examination with single photo emission tomography (SPECT) (CERETEC«) during a relapse period and 2 weeks later there was marked cortical hypoperfusion of the frontal and temporal lobes, especially on the left side as well as in the right parietal lobe. Neuropsychological testing performed 1 week after a relapse showed a reduction in encoding to memory function of verbal learning indicating neocortical damage of the left fronto-temporal region. A follow-up 2 months later after the patient had spontaneously recovered showed only a slight left fronto-temporal disturbance. CT and MRI of the brain were normal although the MRI showed a large and asymmetric mamillary body. Neuropsychological testing 6 years after recovery showed pronounced reduction in short-time verbal and visual memory. Seven years after recovery SPECT demonstrated a normalized frontal perfusion but still a slight hypoperfusion in the left temporal lobe. Our results correlate to autopsy findings in two cases described previously.

- Background - A previous investigation at our department of a young man with typical Kleine-Levin syndrome revealed short-term memory dysfunction as well as hypoperfusion of the temporal lobes on single photon emission tomography (SPECT) (CERETECR) examination, 6 and 7 years after recovery, suggesting long lasting or even permanent cerebral dysfunction. Patients and methods - We investigated four cases with classical adolescent Kleine-Levin syndrome characterized by hypersomnia and typical associated symptoms. We used neuropsychological testing and SPECT (CERETECR) of the brain. The results from the previous report related to above is included. Results - Examination with SPECT (CERETECR) during remission revealed hypoperfusion of the temporal lobes and fronto-temporal region in two of four cases. There were normal findings in two. Neuropsychological testing performed during remission showed reduction in the short-term memory capacity in all four cases. Conclusion - It is striking that all the cases investigated showed short-term memory dysfunction. One patient who had recovered from paroxysmal symptoms (hypersomnia attacks and bulimia) 6 years earlier showed progress in the short-term memory dysfunction. A pathologic condition in the temporal lobes may be suspected in Kleine-Levin syndrome.
