Primary aldosteronism is one of the most common cause of secondary hypertension and can be accompanied with hypokalemia. Rhabdomyolysis with hypokalemia in primary aldosteronism has been rarely reported. We describe a patient of primary aldosteronism who presented with limb-girdle type weakness.
Background: The intermittent delta activity in electroencephalographies (EEGs) of patients with focal brain lesions has been reported to be a marker of an epileptogenic focus. This study investigated the concordance between the current source distribution (CSD) of the interictal epileptiform discharges (IEDs) and that of the background delta frequency bands (DFBs) of the scalp EEG. Methods: We collected scalp EEGs of 13 patients with focal epilepsy that contained uniregional IEDs and unilateral delta to theta slow waves. We applied a distributed source model using LORETA? to determine the CSD of the peak points of the IEDs and the DFBs of the background activity. Results: The CSDs of the DFBs were ipsilateral to the CSDs of the peak point of the averaged IEDs in ten patients, and bilateral with ipsilateral predominance in three patients. In the cases with an ipsilateral CSD of the DFB, 8 of 10 patients had concordance of the CSD localization between the averaged IED and the DFB. In the cases with bilateral CSD of the DFB, 2 of 3 patients had concordance of the CSD localization between the averaged IED and the DFB. Conclusions: The CSD localization and lateralization appear to be concordant between the IEDs and the DFB of background activity in epileptic patients. Therefore, the CSD of the DFB in EEGs with visually observable slow activities may predict those of IEDs.
Background: The compression of 7th cranial nerve by arteries is one of the various causes of hemifacial spasm (HFS).A few previous studies were revealed the relation between the compression of 7th cranial nerve and common trunkanomaly. We evaluated the common trunk anomalies in patients with HFS using MRI and MRA.Methods: From January 2001 to December 2005, 41 consecutive patients (9 men, mean age 54.5
Recurrent transverse myelitis is a rare manifestation of systemic lupus erythematosus. Recurrent transverse myelitis presents the biggest diagnostic problem, since it is common manifestation of multiple sclerosis. But it can also be the only feature or first manifestation in systemic lupus erythematosus. Neurological manifestations and magnetic resonanceimaging can be indistinguishable, and there are no specific diagnostic tools. Here we describe a 59-year-old female having a systemic lupus erythematosus with recurrent transverse myeltitis. No uniform therapeutic protocol exists for systemic lupus erythematous with transverse myelitis, and the prognosis is usually poor. We suggest that aggressivetreatment (usually with pulses of methylprednisolone and cyclophosphamide) might improve the prognosis of systemic lupus erythematosus with transverse myeltis.
Periodic lateralized epileptiform discharges(PLEDs) are usually seen in acute and subacute cerebral lesions. Occasionally PLEDs could be observed in persistent structural lesions. We observed PLEDs-plus in a patient with right basal ganglionic hemorrhage, at 10 months and 13 months after the stroke. The patients suffered two seizures 3 months and 5 days before recording of EEG. PLEDs-plus may persist as an interictal abnormal finding and the rhythmic dischargeof that may be increased by a seizure.
