Chordoid glioma, a recently introduced clinicopathologic entity, is a rare neoplasm occurring mainly in the third ventricle and hypothalamus. The authors had experienced a case of chordoid glioma combined with Rathke's cleft cyst which occurred in the sellar and suparasellar region. Here we report clinical, radiological, and histopathological features of this neoplasm with review of literature

Diencephalic syndrome of infancy which is characterized by progressive and profound emaciation often with normal or accelerated skeletal growth, hyperkinesias, hypotension, and hypoglycemia. The profound emaciation so characteristic this syndrome has yet to be explained. The diencephalic syndrome is caused by low grade astrocytoma, ependymoma in the third ventricle including the hypothalamus. Authers report a case of diencephalic syndrome which was confirmed in this patient with ependymoma in the region of anterior hypothalamus by transcallosal approach.

Olfaction and food intake are interrelated and regulated. In the process of feeding, the metabolic signals in the body and the feeding signals produced by food stimulation are first sensed by the arcuate nucleus of hypothalamus and the nucleus tractus solitarius of brain stem, and then these neurons project to the paraventricular nucleus of hypothalamus. The paraventricular nucleus transmits the signals to other brain regions related to feeding and regulates feeding behavior. In this process, olfactory signals can be transmitted to hypothalamus through olfactory bulb and olfactory cortex to regulate feeding behavior. At the same time, gastrointestinal hormones (ghrelin, insulin, leptin, etc.) and some neurotransmitters (acetylcholine, norepinephrine, serotonin, endocannabinoid, etc.) produced in the process of feeding act on the olfactory system to regulate olfactory function, which in turn affects the feeding itself. This review summaries the research progress of the interaction between olfaction and food intake and its internal mechanism from the aspects of neuronal and hormonal regulation.

Laughter as an epileptic phenomenon is very uncommon. The introduction of the term gelastic epilepsy by Daly and Mulder (1957) may have resulted in less precision in diagnosis. Laughter does not necessarily include Mirth (gelos). Smiling may be volumtary or barely perceptible, whereas the laryngeal and respiratory components of laughter are more likely to be involuntary and are definite. To this time the loction of this epilepsy is said to be related with temporal lobe and hypothalamus. This case which we present with reviewing of the literature has paroxysmally a burst of loud, high-pitched laughter without any emotional expression. It suggests that at the production of this laughter some fasciorespiratory pathways might be involved, and that the start of this epileptic discharge is probably from a lesion of the orbito-frontal area.
