Positron emission tomography can be used to evaluate brain function following perinatal hypoxia. This case report demonstrates transient hypermetabolism in the basal ganglia detected by glucose metabolism positron emission tomography study in a newborn who suffered hypoxic-ischemic encephalopathy and developed dystonic cerebral palsy later. A scan repeated at 4 years of age showed severe hypometabolism in the lentiform nuclei and thalami. Transient hypermetabolism in the basal ganglia following perinatal hypoxia may be related to excitotoxic damage causing permanent neurological symptoms in the form of dystonic cerebral palsy. Thus, positron emission tomography can help predict this form of cerebral palsy in neonates.

Background: Recent studies have suggested a transient glucose hypermetabolism in early phases of Alzheimer's Disease (AD), which is followed by a characteristic glucose hypometabolism in dementia stages. This phenomenon desveres further investigation and it is suggested to be associated to glial/inflammatory or compensatory neuronal responses. Here, we aimed to longitudinally investigate brain glucose metabolism in an AD animal model and explore associated cellular and inflammatory changes.

Febrile Infection-Related Epilepsy Syndrome (FIRES) is an infrequent yet severe form of epilepsy that rapidly evolves into status epilepticus following a febrile episode. Prompt diagnosis coupled with effective treatment strategies is critical for improving patient outcomes. Herein, we describe the case of an 11-year-old male with FIRES who was successfully treated with tocilizumab, resulting in no further seizures or residual disability.

Colorectal cancer is a common malignancy, with the liver being the most frequent site of metastases. [F] Fluorodeoxyglucose ([F]FDG) positron emission tomography/computed tomography (PET/CT) has emerged as a valuable tool in detecting and evaluating liver metastases and extrahepatic disease. Herein, we present a case of a 76-year-old male with colorectal cancer associated with lung and liver metastases.

Aim: A fraction of the Ca released from the sarcoplasmic reticulum (SR) enters mitochondria to transiently increase its [Ca ] ([Ca ] ). This transient [Ca ] increase may be important in the resynthesis of ATP and other processes. The resynthesis of ATP in the mitochondria generates heat that can lead to hypermetabolic reactions in muscle with ryanodine receptor 1 (RyR1) variants during the cyclic releasing of SR Ca in the presence of a RyR1 agonist.

Disruption of the immune system during embryonic brain development by environmental chemicals was proposed as a possible cause of neurodevelopmental disorders. We previously found adverse effects of di-n-octyltin dichloride (DOTC) on maternal and developing immune systems of rats in an extended one-generation reproductive toxicity study according to the OECD 443 test guideline. We hypothesize that the DOTC-induced changes in the immune system can affect neurodevelopment.
