This review deals with the structural, behavioral, and EEG correlates of searching for food and food intake. Data were collected on freely behaving kittens of 1 to 60 days of age with chronically implanted electrodes. The 1st manifestations of hunger involve activation of limbic-reticular structures and electroencephalographic (EEG) activity consisting of fast oscillations of 30-40-60 cps, correlated with general behavioral arousal as manifested by motor restlessness and vocal reactions. The more specific behavior form of hunger--feeding motivation--involves structures that include the motor and parietal cortex, amygdala, and medial hypothalamus; the EEG activity consists of high-amplitude, slow waves of 3-6 or 6-8 cps; and the behavioral correlate is purposeful search for the mother's teat or food. Satiation is associated with activity of the synchronizing structures in the forebrain and lower brain stem, as well as in the relay nuclei that transmit the sensory flow from oral afferents; EEG activity consists of regular rhythms of 10-14 and 2-4 cps; and the behavioral correlate is the act of feeding.

Baclofen is widely used in the treatment of spasticity of spinal origin. It is relatively free of side effects or toxic actions on the nervous system or other organs. Agitation, personality change, and auditory and visual hallucinations have been described following its abrupt withdrawal. One patient with generalized seizures and one with complex partial seizures after baclofen withdrawal have been reported. This paper presents a patient who developed status epilepticus after baclofen withdrawal, and who sustained hypoxic cerebral injury. This observation further emphasizes the possibility of infrequent complications of baclofen therapy, and the advisability of gradual changes in baclofen dosage.

Report of a girl with the epileptic, hydrocephalic and encephalitic form of neurocysticercosis, diagnosed by cerebrospinal fluid and computed tomography exams, during her second year of life and an evolution with multiple types of seizures, prolonged periods of intracranial hypertension due to obstruction in the ventriculoperitoneal shunt, psychomotor regression and blindness until she was 10 years old, when the Lennox-Gastaut syndrome was diagnosed. Nowadays the patient is 16 years old and presents complex partial seizures with automatism not completely controlled with clobazan and oxcarbazepine, associated to left spastic hemiparesis, universal hyperreflexia, psychomotor agitation, self-mutilation, amaurosis and severe mental retardation. The association between neurocysticercosis and Lennox-Gastaut syndrome was first described in 1973 by Frochtengarten & Scarante in a Brazilian girl with a similar clinical picture.

Among 3 varieties of Xanthomonas campestris, the variety ocumo (X. campestris pv. ocumo), showed the greatest capacity for producing xanthan. This bacteria grows appropriately and produces this polysaccharide in a wide diversity of carbohydrate sources. However, this strain does not produce xanthan when the carbohydrate comes from lignocellulosic materials. The glucose syrup FAVEPRO was the carbon source that showed the best yield (23 g/l) with the greatest viscosity (7000 cps) of xanthan. The optimum production conditions in 1 L erlenmeyer flasks, with a working volume of 0.2 L and in a 14 L (stirred tank type bioreactor) with a working volume of 10 L, were the following: total sugar 5%, urea 0.05%, di-potassium hydrogen phosphate 0.5%, pH 7.5, inoculum 10%, temperature 30 degrees C, agitation 250-1000 rpm and aereation 0.3-1.0 vvm. This strain of X. campestris pv. ocumo was able to produce xanthan (10 g/l) in a culture medium based on a previously treated agricultural waste, called soluble acid extract of cassava bark. The viscosity of this medium increased up to 1500 cps.

Frontal lobe epilepsy is an unusual form of complex partial seizures associated with behavioral changes including fear, agitation, kicking, and screaming. The seizures are often missed or mistaken for psychiatric problems or sleep disorders. We report 2 unusual patients presenting with psychosis who were found to have frequent frontal lobe seizures. Treatment of the seizures with carbamazepine resulted in complete resolution of their psychiatric symptoms. The relationship between frontal lobe seizures and psychosis is explored.

Language function in the postictal state can be successfully assessed and provides valuable information on seizure localization and spread. Several studies have shown that postictal paraphasic errors and ictal speech have value for seizure localization. The Cincinnati method is a simple, repeatable test that involves presenting a single test sentence on a card and asking the patient to read the sentence repeatedly until it is read correctly. It increases the yield of detecting paraphasic errors and ictal speech, and provides a quantitative measure of language recovery known as the postictal language delay, defined as the time from the end of the EEG ictal discharge until the test sentence is read correctly. This language testing method has been used for all patients admitted to the epilepsy monitoring unit at the Cincinnati Epilepsy Center for more than 20 years and has been shown to: (1) lateralize temporal lobe complex partial seizures; (2) identify when temporal lobe complex partial seizures spread to the dominant hemisphere; (3) identify patients with atypical language lateralization; (4) distinguish between temporal and frontal complex partial seizures; and (5) provide some insight into speech prosody changes in nondominant temporal lobe complex partial seizures. The method has some limitations because it requires vigilance of the patient and direct interaction by the technologist, and may be incomplete as a result of patient agitation, but has been successfully completed in more than 80% of patients admitted to the epilepsy monitoring unit. This highly cost-effective test provides important information on seizure localization and spread; is easily taught to technologists, nurses, and family members; and should be added to testing procedures in all epilepsy monitoring units.

The purpose of this study was to optimize the process parameters of a poorly soluble drug by top down media milling process using different polymer systems. Process parameters including agitation rate (RPM), size of grinding media and drug content were studied through a Quality by Design (QbD) approach, using three different polymeric stabilizers (HPMC 3 cps, PVP K-30 and HPC-EXF) with the addition of Vitamin E TPGS as a surface active agent. From the statistical analysis, the RPM of the media milling was determined to be the most significant process parameter with respect to influence on particle size. The effects of varying the size of grinding media or drug content were not found to be as significant as the effects of RPM. Finally, the polymeric stabilizer played an important role in the production of nanoparticles. Among the different polymers, HPMC stabilized systems demonstrated superior results with regards to the consistency in producing successful nanoparticles and inhibition of crystal growth during storage. This study established the interplay among the formulation parameters in order to select the design space, which helped us in the identification and rank ordering of critical and noncritical variables related to the quality attributes of nanosuspension formulation during the early phase of product development.

Posterior reversible encephalopathy syndrome (PRES) is a disorder characterized by gray and white matter abnormalities in the temporal, parietal, and occipital lobes of the brain. Its etiology has been attributed to renal failure, immunosuppressive drugs such as cyclosporine and tacrolimus, and other potential entities leading to acute hypertension. Clinical findings include headaches, altered mental status, seizures, visual changes, and focal neurologic deficits. We report the case of a child who developed PRES with intracerebral and subarachnoid hemorrhages associated with tacrolimus exposure 10 days after heart transplantation for restrictive cardiomyopathy. The patient initially presented with complex partial seizures, headache, agitation, and hypertension. Head MRI was suggestive of PRES along with intracerebral and subarachnoid hemorrhages. Tacrolimus was discontinued and blood pressure was controlled. The patient's encephalopathy resolved, but he has had ongoing neurologic symptoms secondary to hemorrhage. Generally, PRES is less common in children than in the adult population and is a rare complication of calcineurin inhibitors (CNI). Presentation with secondary hemorrhage also can occur. In children receiving CNIs presenting with new neurologic symptoms, PRES should be considered as prompt discontinuation of the offending agent can induce resolution of symptoms. Children can develop hemorrhage in the context of PRES, leading to increased morbidity.
