First, the author makes reference to the psycho pathological and nosological questions associated with paranoid and schizophrenia-like psychoses in epilepsy and in particular to the non resolved problem of a distinction between these epileptic syndromes and the ones of schizophrenia. Starting from a phenomenological analysis of basic existential structures such as encounter or interpersonality, temporality and spatiality in a typical case of paranoid psychosis in epilepsy, the author tries to establish formal criteria which allow to distinguish these psychoses from schizophrenia. Thus it could be demonstrated that the structure of the encounter in the psychotic epileptic is quite conserved, both in what refers to the real and the delusional partner. His spatiality is characterized by the phenomenon of narrowness and his temporality by harassment, being necessary to underline the fact that, unlike what happens in schizophrenia, in the paranoid psychoses of epilepsy the space maintains its unity and the time its continuity. We could summarize the substantive difference between both types of paranoid psychoses with the following words: in paranoid syndromes in epilepsy what occurs is a change of state "within the world", while in schizophrenia it is a rather a modification of the "being-in-the world" itself or, with other words, it deals with a going out from the world constituted as community.

Cyclo(His-Pro) (CHP) is a peptide endogenous to human brain and cerebrospinal fluid (CSF). In animal studies administration of exogenous CHP augments dopaminergic neurotransmission. To explore the role of this peptide in schizophrenia, a disease characterized by a hyperdopaminergic state, we have measured CSF CHP levels in control, never-medicated schizophrenics and medicated schizophrenics. Our data show a 53% increase in CSF levels of CHP in never-medicated schizophrenics (p = 0.015), and a 25% increase in medicated schizophrenics when compared to controls. We speculate that CHP may contribute to the expression of hyperdopaminergic symptoms in schizophrenia.

We reported a case of acute water intoxication from compulsive water-drinking, who showed triphasic waves on EEG. The patient was a 50-year-old man who had been undergoing medical treatment in a mental hospital since he was suffering from schizophrenia diagnosed at the age of 35. He had sometimes had a tendency to drink a large amount of water since 45 years old. He began to drink water compulsively since three days ago. He vomited just after he drank excessive water with his mouth directly to the tap for several minutes, and soon fell into loss of consciousness. He was transmitted to our hospital because of acute consciousness disturbance on the next day. On neurological examination, he was profoundly comatose with miosis and conjugate deviation to the right side. His extremities showed decorticate posturing. On admission, serum sodium level was 101 mEq/l, and plasma osmolality was 208 mOsm/l. Serum enzymes derived from muscle and myoglobin were markedly elevated. But there was no laboratory evidence of the other metabolic disorders such as hepatic or renal disease. Computed tomography of the brain disclosed severely diffuse swelling with largely obliterated sulci and narrowed ventricles. EEG showed triphasic waves predominantly over centro-parieto-occipital portion, behind which there was slow wave activity with a loss of normal alpha wave activity. Immediately, treatment began by a combination of saline and glyceol infusion for the purpose of correcting severe hyponatremia, subsequently removing brain edema. As serum sodium level gradually returned to normal, the brain CT findings were getting better.(ABSTRACT TRUNCATED AT 250 WORDS)

The only thing for which Serbski is known nowadays is that, following his death in 1917, the Institute of Medico-Legal Psychiatry in Moscow was named after him. It was here, half a century later, that was made the diagnosis of sluggish schizophrenia from the observation of numerous dissidents. Yet the biography of this pupil and successor of Korsakov is that of a liberal, who championned the cause of human rights under the ancient regime, and in particular those of the mentally ill. His theoretical writings, published in the medico-psychological Annales in 1903-1904, are a contribution to the critique made by the French speaking school of the extended conception of dementia praecox developed by Kraepelin in 1899, and taken up by Bleuler in 1911, with his description of the group of schizophrenias. Serbski does not then deserve the opprobrium which the proper condemnation of the use of psychiatry for political issues has inflicted up on his name.

The ventral tegmental area (VTA) is the major dopaminergic (DA) center responsible for the innervation of the prefrontal cortex, nucleus accumbens, and entorhinal region. These areas have been causally implicated in schizophrenia. Thus, the existence of brainstem pathology could explain many of the previously reported findings in schizophrenic (SC) patients. The authors focus on uncovering brainstem abnormalities in schizophrenia by studying the autopsied material of a patient having an early onset of symptomatology. The patient was evaluated at the age of 10 years for manneristic behavior, a speech disorder, and violence. Prominent auditory hallucinations became apparent years later. His mental status and ability for self-care steadily deteriorated until he succumbed to pneumonia at age 22. Microscopic examination of the brain showed central chromatolysis of neurons and mild gliosis in a restricted distribution of the brainstem and thalamus. Cell loss and cytoarchitectural disruption were evident in the frontal lobes, prepyriform cortex, and entorhinal region. The neuropathological changes were interpreted as a chronic derangement in the function of neurons of the rostral brainstem tegmental area and medial thalamus with secondary involvement of their terminal projection sites.

A 46-year-old businessman suddenly became to behave curiously on the morning, September 1, 1988. He forgot how to go through an automatic ticket gate, which he used every day. In his company, he also forgot how to open the cash box, and he wrote a meaningless report for his business. From the night on that day, he had experienced auditory hallucination in which whispering words of some criticism to his performance for a few days. On the next day, he was admitted to a psychiatric hospital because he was suggested to have schizophrenia. By day 6 after the onset, his curious symptoms completely disappeared. However, slight verbal memory disturbance and cognitive dysfunction still remained. Because the brain CT on day 6 showed a small localized subcortical infarction in the left hemisphere he was transferred to our clinic on day 20 to elucidate the relation between the abnormal behavior and the infarction. His blood pressure was 116/64 mmHg and pulse was regular 63/min. He was clear and did not have any neurological deficit. He kept his episodic memory regarding the events at the onset and could almost recall them precisely. Results of standard blood tests, electrocardiogram, ultrasound cardiogram, electroencephalogram as well as cerebral angiography were normal. Computed tomography and magnetic resonance imaging showed an infarcted lesion in the genu of the left caudate nucleus, adjacent to the anterior part of the thalamus.(ABSTRACT TRUNCATED AT 250 WORDS)

The development of psychiatric thought has always been in close association with the pineal gland. The importance of a relationship between pineal, and mental functions was stressed by Descartes when he placed the seat of rational thought as well as the confluence of body and soul in this organ (Cf. Descartes, L'Homme, 1664). His writings exerted such a strong influence that, quite soon indeed, physicians started regarding this gland as being the source of many mental disorders. In an attempt to find and explain a possible link between mental abnormalities, and the discovery of calcified pineals in necroptic studies, many theories were put forward during the 18th, and the 19th century. Afterwards, the importance of the gland went almost unnoticed until 1920, when Becker treated psychotic patients with pineal extracts. An up-to-1950 review by Kitay and Altschule (1954) reported 17 cases where pineal extracts were successfully injected to psychotic patients. In the present review, the author tries and summarizes several reports dealing with the influence of the pineal function on affective disorders, schizophrenia, sleep cycle, Parkinson disease, etc., as a contribution to future research work in this field.

The authors have investigated the levels of free amino acids and of the total fraction of medium molecules in the blood serum of patients with the paranoid form of continuously progressive schizophrenia. It has been demonstrated that these parameters are different in clinically normal individuals versus schizophrenics. The concentrations of free amino acids were the highest in people aged 40 to 50 years (Cys, Ala, Lys, Asp, Thr, Tyr, Try, Val, Leu, Ile) being considerably lower in individuals aged 50 to 60 years (Cys, Ala, Tyr) and over 60 years (Lys, His, Asp, Tyr, Try) which corresponds to the highest activity of the process in patients aged 40 to 50 years and its stabilization in older age.

The case of a sixteen-year-old youth is presented on the basis of correspondence over the years 1806 to 1813. His initial breakdown was probably due to hebephrenic schizophrenia, but clinical detail is defective and the evidence is chiefly about the difficulties of recovery and rehabilitation. The case is discussed in relation to the treatment he received and against the background of provision for insanity and psychiatric methods and ideas in Ireland during the period.

A 19-year-old man developed a schizophrenia-like psychosis after ingesting isosafrole. His use of amphetamines and LSD failed to produce a similar syndrome. Isosafrole may provide another biochemical model for schizophrenia.
