INTRODUCTION
Tumours of the tectal region form, within the group of gliomas of the brain stem, a sub group with better prognosis which require a different therapeutic strategy.
OBJECTIVES
A retrospective review of tectal tumours in children to find the most suitable therapeutic approach and the prognosis to be expected.
PATIENTS AND METHODS
We reviewed… (More)

INTRODUCTION
Recently a series of cases has been reported characterized by myoclonic crises similar to those occurring in benign myoclonic epilepsy of childhood. However, these crises only occurred after unexpected tactile or auditory stimuli. These clinical conditions represent a new epileptic syndrome, which is age-dependent and has been called benign… (More)

OBJECTIVES
To attempt to replicate previous reports that polymorphic variation in the DCP1 gene causes increased susceptibility to the development of Alzheimer's disease, either on its own or in interaction with the effects of the gene for apolipoprotein E (APOE).
METHOD
Subjects older than 65 years of age consisting of 81 dementia patients diagnosed as… (More)

INTRODUCTION AND OBJECTIVE
Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disease of the central nervous system. This study is based on clinical symptoms and diagnostic tests employed.
PATIENTS AND METHODS
We describe a seven children series indicating the initial neurologic abnormalities, diagnostic tests, treatments used… (More)

For the zero-range interaction providing a given mass M 2 of the two-body bound state, the mass M 3 of the relativistic three-boson state is calculated. We have found that the three-body system exists only when M 2 is greater than a critical value M c ≈ 1.43 m (m is the constituent mass). For M 2 = M c the mass M 3 turns into zero and for M 2 < M c there is… (More)

The numerical solutions of the non-relativistic Yukawa model on a 3-dimensional size lattice with periodic boundary conditions are obtained. The possibility to extract the corresponding – infinite space – low energy parameters and bound state binding energies from eigensates computed at finite lattice size is discussed.

Bethe-Salpeter (BS) equation in Minkowski space for scalar particles is solved for a kernel given by a sum of ladder and cross-ladder exchanges. The solution of corresponding Light-Front (LF) equation, where we add the time-ordered stretched boxes, is also obtained. Cross-ladder contributions are found to be very large and attractive, whereas the influence… (More)

We study relativistic effects in a system of two scalar particles interacting via a scalar exchange in the Light Front Dynamcis framework. The results are compared to those provided by Bethe-Salpeter and non relativistic equations. It is found in particular that for massive exchange, the relativistic description is of crucial importance even in the limit of… (More)

For a relativistic system of two scalar particles, we find the Bethe-Salpeter amplitude in Minkowski space and use it to compute the electromagnetic form factor. The comparison with Euclidean space calculation shows that the Wick rotation in the form factor integral induces errors which increase with the momentum transfer Q 2. At JLab domain (Q 2 = 10 GeV 2… (More)
