Predicting aging transition using Echo state network.

It is generally known that in a mixture of coupled active and inactive nonlinear oscillators, the entire system may stop oscillating and become inactive if the fraction of active oscillators is reduced to a critical value. This emerging phenomenon, called the "aging transition," can be analytically predicted from the view point of cluster synchronization. One can question whether a model-free, data-driven framework based on neural networks could be used to foretell when such a system will cease oscillation.

Quetiapine-induced Diabetic Ketoacidosis.

Psychomotor retardation and extrapyramidal symptoms have limited the conventional antipsychotic use. Atypical antipsychotics though widely prescribed with good tolerability and efficacy, the metabolic complications associated with them are of clinical importance. Diabetic ketoacidosis (DKA) is a fatal complication of atypical antipsychotic use.

Factitious Disorder - A Rare Cause for Unexplained Epistaxis.

Epistaxis or nasal bleeding is a common condition which may be severe enough to warrant an urgent medical or surgical treatment. Factitious epistaxis is a rare entity. Due to a lack of exposure in complex behavioral issues during undergraduate training, it is quite natural on the part of a surgeon to miss the underlying emotional phenomena.

Arachnoid Cyst and Psychosis: The Troublemaker or Innocent Bystander.

Organic underpinning of a psychotic disturbance is often missed. Arachnoid cysts are considered a rare neurological tumor, few of which exhibit any symptomatology. In most cases, they are diagnosed by accident.

Psychosis in Secondary Empty Sella Syndrome following a Russell's Viper Bite.

Hypopituitarism can present with psychiatric symptoms. We report a unique case of psychosis in clear consciousness in a case of hypopituitarism due to the secondary empty sella syndrome following a Russell's viper bite which was untreated and presented with psychotic symptoms for past 13 years following the snake bite. After the diagnosis of psychosis due to hypopituitarism was made, the patient was treated with levothyroxine and prednisolone supplements and his psychotic symptoms subsided without any psychotropic drugs.
