Mozart k.545 mimics mozart k.448 in reducing epileptiform discharges in epileptic children.

Mozart K.448 has been shown to improve cognitive function, leading to what is known as the Mozart Effect. Our previous work reveals positive effects of Mozart K.448 in reducing epileptiform discharges in epileptic children. In this study, we evaluated the effect of Mozart K.545 and compared the effects with those of Mozart K.448 on epileptiform discharges in children with epilepsy. Thirty-nine epileptic children with epileptiform discharges were included in the study. They received electroencephalogram examinations before, during, and after listening to Mozart K.448 and K.545, one week apart, respectively. The frequencies of epileptiform discharges were compared. There was a significant decrease in the frequency of epileptiform discharges during and right after listening to Mozart K.448 and K.545 (reduced by 35.7 ± 32.7% during Mozart K.448 and 30.3 ± 44.4% after Mozart K.448; and 34.0 ± 39.5% during Mozart K.545 and 31.8 ± 39.2% after Mozart K.545). Spectrogrammatic analysis of the two pieces of music demonstrated that both share similar spectrogrammatic characteristics. Listening to Mozart K.448 and K.545 decreased the epileptiform discharges in epileptic children. This suggests that Mozart K.448 is not the only piece of music to have beneficial effects on children with epilepsy. Other music with lower harmonics may also decrease epileptiform discharges in epileptic children.

The long-term effect of listening to Mozart K.448 decreases epileptiform discharges in children with epilepsy.

Mozart's Sonata for Two Pianos in D major, K.448 (Mozart K.448), has been shown to improve mental function, leading to what is known as the Mozart Effect. Our previous work revealed that epileptiform discharges in children with epilepsy decrease during and right after listening to Mozart K.448. However, the duration of the effect was not studied. In the study described here, we evaluated the long-term effect of Mozart K.448 on epileptiform discharges in children with epilepsy. Eighteen children with epilepsy whose seizures were clinically well controlled with antiepileptic drugs were included. For each child, EEGs had revealed persistent epileptiform discharges for at least 6 months. These patients listened to Mozart K.448 for 8 minutes once a day before bedtime for 6 months. Epileptiform discharges were recorded and compared before and after 1, 2, and 6 months of listening to Mozart K.448. All of the children remained on the same antiepileptic drug over the 6 months. Relationships between number of epileptiform discharges and foci of discharges, intelligence, epilepsy etiology, age, and gender were analyzed. Epileptiform discharges significantly decreased by 53.2±47.4, 64.4±47.1, and 71.6±45.8%, respectively, after listening to Mozart K.448 for 1, 2, and 6 months. All patients except those with occipital discharges showed a significant decrease in epileptiform discharges. Patients with normal intelligence and idiopathic epilepsy had greater decreases than those with mental retardation and symptomatic epilepsy. Age and gender did not affect the results. We conclude that long-term listening to Mozart K.448 may be effective in decreasing epileptiform discharges in children with epilepsy in a chronologically progressive manner.

Mozart K.448 acts as a potential add-on therapy in children with refractory epilepsy.

Mozart's Sonata for two pianos in D major, K.448 (Mozart K.448), has been shown to improve mental function, leading to what is known as the Mozart effect. Our previous work revealed that epileptiform discharges in children with epilepsy decreased during and immediately after listening to Mozart K.448. In this study, we evaluated the long-term effects of Mozart K.448 on children with refractory epilepsy. Eleven children with refractory epilepsy were enrolled. All of the patients were diagnosed as having had refractory epilepsy for more than 1 year (range =1 year to 6 years 4 months, mean =3 years 11 months) and had been receiving at least two antiepileptic drugs (AED). During the study period, they listened to Mozart K.448 once a day before bedtime for 6 months. Seizure frequencies were recorded 6 months before they started listening to this music and monthly during the study period. All of the patients remained on the same AEDs during the 6-month study period. Frequencies of seizures were compared before and after listening to Mozart K.448. Eight of eleven patients were seizure free (N=2) or had very good responses (N=6) after 6 months of listening to Mozart K.448. The remaining three (27.3%) showed minimal or no effect (effectiveness <50%; unmodified or worsened seizure frequency). The average seizure reduction was 53.6 ± 62.0%. There were no significant differences in seizure reduction with IQ, etiology, or gender. We conclude that Mozart K.448 should be further studied as a potential add-on therapy in the treatment of children with refractory epilepsy.

Parasympathetic activation is involved in reducing epileptiform discharges when listening to Mozart music.

OBJECTIVE: Listening to Mozart K.448 has been demonstrated to improve spatial task scores, leading to what is known as the Mozart effect. Our previous work revealed the positive effects of Mozart K.448 in reducing epileptiform discharges in children with epilepsy. However, the mechanism remains unclear. parasympathetic activation has been shown to help seizure control in many studies. In this study, we investigated the effect of Mozart music on epileptiform discharges and autonomic activity. METHODS: Sixty-four epileptic children with epileptiform discharges were included. They all received electroencephalogram and electrocardiogram examinations simultaneously before, during, and after listening to Mozart K.448 or K.545. The total number of epileptiform discharges during each session (before, during, and after music) were divided by the duration (in minutes) of the session and then compared. Heart rate variability including time and frequency domain analysis was used to represent the autonomic function. RESULTS: The results showed that epileptiform discharges were significantly reduced during and right after listening to Mozart music (33.3 ± 31.1% reduction, p<0.001, during Mozart K.448 and 38.6 ± 43.3% reduction, p<0.001, during Mozart K.545) (28.1 ± 43.2% reduction, p<0.001, after Mozart K.448 and 46.0 ± 40.5% reduction, p<0.001, after Mozart K.545). No significant difference was noticed between the two pieces of music. The reduction was greatest in patients with generalized seizures and discharges. Significant increases in high-frequency (HF), the square root of the mean squared differences of successive RR intervals (RMSSD), the standard deviation of differences between adjacent RR intervals (SDSD), and a decrease in mean beats per minute (bpm) were found during listening to Mozart music. Most of the patients with reduced epileptiform discharges also showed a decreased LF/HF ratio, low-frequency normalized units (LF nu), mean bpm, and an increased high-frequency normalized units (HF nu). CONCLUSIONS: Listening to Mozart music decreased epileptiform discharges in children with epilepsy. The majority of these patients showed an increase in parasympathetic tone during music exposure. SIGNIFICANCE: Our results suggested that Mozart music stimuli induced parasympathetic activation which may be involved in the effect of music in reducing epileptiform discharges and the recurrence rate of seizures.

Mozart K.448 and epileptiform discharges: effect of ratio of lower to higher harmonics.

PURPOSE: Certain music has been shown to improve mental function, leading to what is known as the Mozart effect. This study measured the impact of Mozart's Sonata for two pianos in D major, K.448, on different epileptic foci of epileptiform discharge in Taiwanese children (n=58) with seizure disorders and investigated the characteristics of the musical stimulus presented that resulted in epileptiform discharge reduction. METHODS: We examined the relationship between the number of discharges with the foci of epileptiform discharge (n=6), sleep state, gender, and mentality. A continuous electroencephalogram was recorded before, during and after exposure to Mozart's Sonata for two pianos in D major, K.448 (piano K.448), and the frequencies of discharges were compared. The study was repeated a week later using digitally computerized string version of the same musical stimulus (string K.448), in patients who responded to piano K.448 with the largest reduction in interictal discharges (n=11). RESULTS: Interictal discharges were reduced in most (81.0%) patients and varied greatly (33.10+/-28.33%) as they listened to the piano K.448 (more fundamental tones and lower harmonics). Patients with generalized or central discharge showed the most improvement. In most patients (76.1%), the decrease in epileptiform discharges continued after the music ended. The state of wakefulness, gender and mentality did not affect the results. Although the string K.448 had a larger number of higher harmonics in the spectrogram analysis, the discharges were not reduced at all when listening to this music. CONCLUSION: These results suggest that listening to Mozart K.448 for two pianos reduced epileptiform discharges in children with epilepsy. This study suggests that it is possible to reduce the number of epileptiform discharges in some patients by optimizing the fundamental tones and minimizing the higher frequency harmonics.

Septic arthritis of the hip joint in cervical cancer patients after radiotherapy: Three case reports.

Cervical cancer patients may experience hip problems related to the cancer itself or therapeutic management for the cancer. Septic arthritis should be one of the possibilities but there have been no reports on this. Here we present three patients who developed hip problems more than two years after radiotherapy with or without a radical operation. One patient was managed as septic arthritis because of significant inflammatory signs around the affected hip joint even though the causative organism was not confirmed. Succeeding total hip arthroplasty functioned well and had no recurrence of infection. The hip problems of the other two patients were diagnosed as radiation osteonecrosis of the femoral head initially. However, Bacteroides fragilis infection was found several months after total hip arthroplasties. Radiotherapy to the pelvis may damage the hip joint and compromise host-defense mechanisms of the pelvic region. Both factors may increase the possibility of infection of hip joints. Further clinical evidence is needed to understand whether subacute or chronic anaerobic infection could also be one of the causes leading to progressive destruction of the femoral head.
