Involuntary rhythmic leg movements in childhood is an uncommon condition, the generators of which remain unknown. We report on a male 3 years of age with distinct features providing important clues concerning the location of one of these generators. At the age of 7 months, the previously healthy young male started with low frequency, rhythmic, and continuous
(both during wakefulness and sleep) flexion/extension movements of the lower limbs. Movements interfered significantly with gait acquisition, and, despite normal
cognitive development, he was able to walk only at age 2 years, 4 months. The neurologic examination revealed the absence of automatic stepping in the neonatal
period, but was otherwise normal. A polygraphic electroencephalogram/electromyogram EEG/EMG)
recording, at the age of 2 years, 9 months, revealed rhythmic and ...

The introduction of extracorporeal shock wave lithotripsy (ESWL) and the development of "minimally invasive" endourological procedures have completely changed the management of urinary calculi. Nevertheless, some aspects in this field still remain controversial. Conservative management is the first option, when the stone can pass spontaneously. The majority of the patients can be successfully treated with ESWL without anaesthesia and in an ambulatory setting or with a 24 H admission. ESWL failures (1 to 2%) and some difficult calculi (cystine calculi, staghorn calculus, stones of great volume and some ureteral stones) can benefit with endourological or percutaneous procedures alone or in association with ESWL. The classical indication for open surgery has changed significantly and surgery is now considered only in some difficult cases ...
Panayiotopoulos syndrome (PS) is a common epilepsy syndrome associated with rare clinical seizures and unknown
localization of the epileptogenic area. Despite findings of normal development in patientswith PS, recent neuropsychological studies point to subtle and diverse cognitive impairments. No well-outlined hypothesis about the localization of the brain dysfunction responsible for these impairments has been proposed.We further
explored the cognitive dysfunctions in PS andmade inferences on the most likely anatomical localization of brain
impairment. A group of 19 patients (aged 6–12) with PS was rated according to spike activity and lateralization.
The patients were submitted to a neuropsychological evaluation to assess general intelligence, memory, language,
visual–perceptual abilities, attention, and executive functions. Usin...
Objective: Gelastic seizures are a frequent and well established manifestation of the epilepsy associated with hypothalamic hamartomas. The scalp EEG recordings very seldom demonstrate clear spike activity and the information about the ictal epilepsy dynamics is limited. In this work, we try to isolate epileptic rhythms in gelastic seizures and study their generators.
Methods: We extracted rhythmic activity from EEG scalp recordings of gelastic seizures using decomposition in independent components
(ICA) in three patients, two with hypothalamic hamartomas and one with no hypothalamic lesion. Time analysis of these rhythms and inverse source analysis was done to recover their foci of origin and temporal dynamics.
Results: In the two patients with hypothalamic hamartomas consistent ictal delta (2–3 Hz) rhythms were present, with subco...
