Mu rhythm: clinical assessment of the atypical type]

Of 5,218 patients who received EEG examination at our laboratory during a 9-month period in 1989, 241 showed the 7-13 Hz arch-shaped activity originating from over the Rolandic area known as mu rhythm. These subjects were divided into two groups as follows: Group 1, 171 subjects showing typical mu rhythm, i.e., recorded during wakefulness and not affected by visual stimulation but blocked voluntary movements or tactile stimuli; and, Group 2, 70 subjects showing atypical mu rhythm, i.e., accentuated or activated by drowsiness, photic stimuli, or hyperventilation. No difference between the two groups was found with regard to frequency, amplitude or origin of the mu rhythm. Age distribution for Group 1 showed a peak between the ages of 6 and 15 (67.5%), while that for Group 2 peaked between the ages of 11 and 15 (35.7%) considering high incidence in older age range. There was no significant difference between the two groups in regard to gender. Although both groups showed a high incidence of epilepsy, Group 2 showed higher incidence of intractable epilepsy (p less than 0.05), as well as of severe intracranial trauma and of organic brain disease. On EEG recorded among epileptic patients, paroxysmal discharge was more frequent in Group 2 (p less than 0.01), although no other difference between the two groups was observed. Atypical mu rhythm may indicate more severe epilepsy, and careful observation of patients with atypical mu rhythm is recommended.     

A case of aneurysm of the inferior left ventricular wall

Aneurysms of the inferior left ventricular wall represent only a small fraction of all aneurysms that have been reported in surgical series. And in comparison to anterior left ventricular aneurysms, a comparatively higher percentage of reported inferior wall aneurysms was classified as false. A 73-year-old male was admitted for acute inferior myocardial infarction. Three weeks after admission, cardiac catheterization was carried out. Coronary arteriography revealed triple vessel disease and left ventriculography showed an aneurysm of the inferior left ventricular wall, whose feature near the mitral annulus was multiple fenestrations. Left ventricular aneurysmectomy and aortocoronary bypass grafting to the left anterior descending artery were simultaneously performed under cardiopulmonary bypass with moderate hypothermia. The pathological feature was a true aneurysm. The postoperative course was uneventful.     

Multiple sclerosis and headache co-morbidity. A case-control study

The prevalence of primary headache (PH) in a multiple sclerosis (MS) sample vs. control healthy subjects was investigated at a neurological clinic in 2004–2005: 122 of 238 (51%) MS patients and 57 of 238 (23%) controls proved to be affected by headache. The groups did not differ for the rates of PH types. Headache types of MS patients were comparable to those of PH patients that were observed at the same institute in a case-control comparison. First symptoms of headache preceded those of MS in two thirds of cases. Headache features did not significantly change after MS onset. Comorbidity of MS and PH could be explained by some common clinical and biological traits.     

Definition of An Optimal First-line Chemotherapy in Metastatic Breast Cancer

Single-agent chemotherapy of metastatic breast cancer is the treatment of choice in patients with slow tumor progression and asymptomatic disease. In this patient group, the choice of drugs is based more on good tolerability than on efficacy. By contrast, symptomatic or rapidly progressing disease requires the use of highly active regimens where more weight is put on reliable antitumor activity. While anthraycline-based combination regimens have set the standard of effective treatment, the addition of docetaxel (and to a lesser extent paclitaxel) has improved tumor response, but failed to induce a consistent prolongation of survival. Based on retrospective analyses, it is hypothesised that the combined use of anthracyclines and taxanes in first-line therapy may be most beneficial in defined subgroups: after adjuvant chemotherapy, in patients with HER-2 gene amplification, possibly also in patients with rapidly progressing visceral disease.
