A New Method of Eliciting Pyramidal Tract Impairment in Adults.

Background: To suggest a new way of eliciting pyramidal tract dysfunction in adults since the most widely utilized plantar reflex, which is the Babinski reflex, has limitations with different reliability and consistency among different examiners.

Materials And Methods: 168 adult subjects were examined for the new sign in addition. It consists of just an observation of the patient’s feet and toes in a conscious patient looking for the extension of the great toe along with fanning, spreading and plantar flexion of the small toes either at rest or when patient elevates one leg up at a time.

Celery root extract as an inducer of mania induction in a patient on venlafaxine and St John's Wort.

Celery root belongs to a group of plants classified as the umbelliferous family, which contains phytoestrogens. Phytoestrogens are structurally similar to estrogen as they share a pair of hydroxyl groups and phenolic ring, which enables them to bind to estrogen receptors directly, making them a herbal remedy for low estrogen states such as menopause. We present a case of a female patient with depression who was stabilized on venlafaxine and St John's Wort, and who developed a manic episode due to elevated serum venlafaxine levels after she started taking celery extracts for menopausal related issues.

Autism Spectrum Disorder and Chiari 1 Malformation Co-occurring in a Child.

Very few studies have shown associations between autism spectrum disorder, attention deficit hyperactivity disorder and Chiari 1 malformation. Here, we report an 10-year-old male that presented after having seizures with a history of Chiari 1 malformation, autism spectrum disorder and ADHD with moderate mental retardation and speech delay. This case highlights the fact that autism spectrum disorder as biologically based neurodevelopmental disorder with altered brain growth may be associated with Chiari 1 malformation and ADHD.

Delayed Facial Nerve Palsy after Seat Belt Induced Injury.

Blunt trauma causing facial nerve palsy and facial nerve trauma due to seat belt injury is rarely reported. We describe a 63 year old female who was involved in a road traffic accident without any imaging evidence of temporal bone fracture developing left facial nerve palsy on the second day. We discuss the pathophysiology of this condition and the need to be aware of this unusual complication when evaluating patient with blunt trauma to the face.

Olanzapine produces trophic effects in vitro and stimulates phosphorylation of Akt/PKB, ERK1/2, and the mitogen-activated protein kinase p38.

Olanzapine has previously been shown to stimulate the growth of neuronal cells in culture. A major goal of the present studies was to determine if olanzapine also provided neuroprotection to pheochromocytoma (PC12) cells, SH-SY5Y neuroblastoma cells, and primary cultures of rat cortical neurons. Olanzapine was mitogenic and enhanced the survival of PC12 cells, SH-SY5Y cells and 3T3 preadipocytes, but not L6 myoblasts or myeloma cells.

Efficacy of venlafaxine for the long term treatment of chronic pain with associated major depressive disorder.

Background: This was an open-label, single-center study of the long-term efficacy and effectiveness of venlafaxine extended release (XR) in the treatment of chronic pain and depression in outpatients. All patients have been diagnosed with major depressive disorder (MDD) of various types, with or without chronic pain, and had previously failed treatment with either tricyclic antidepressants (TCAs) or selective serotonin reuptake inhibitors (SSRIs).

Methods: Efficacy of treatment was determined using the 21-item Hamilton Rating Scale for Depression (HAMD-21), the Visual Analogue Scale (VAS) for the evaluation of pain, and a 12-item quality of life scale (QOL).

Cytotoxicity of conventional and atypical antipsychotic drugs in relation to glucose metabolism.

The goal of these studies was to analyze the cytotoxicity of both the conventional and atypical antipsychotic drugs in relation to their effects on glucose metabolism. The drugs were evaluated for their effects on the viability of PC12 cells, which are an established model of neuronal cells in culture. In general, the conventional drugs, such as chlorpromazine, fluphenazine and pimozide, were more toxic than the atypical drugs, including clozapine, quetiapine and risperidone.
