Brain injuries namely traumatic brain injuries (TBI) and subarachnoid haemorrhage (SAH) are relevant causes of acquired adult hypopituitarism, perhaps more prevalent than ever believed. TBI represent a major health problem with an annual incidence of 300 cases per 100.000. SAH affects six new cases per 1.000.000 habitants in USA. In Belgium we estimate nearly 30.000 new TBI cases and 600 SAH cases per year. In the English literature, TBI secondary hypopituitarism has been well documented in 14 retrospective and prospective series accounting for 1.077 cases. In all these series the main pituitary deficits were: GH (14%), ACTH (14%), gonadotrope (18%), TSH (7%) and diabetes insipidus (4%). SAH was documented as a cause of hypopituitarism in three retrospective series accounting for 110 cases and in one prospective series. In all these series main pituitary deficits were GH (25%), ACTH (15%), gonadotrope (8.5%), TSH (6%) and diabetes insipidus (4%). In this review, we analyze recent data and discuss diagnostic and treatment features of secondary hypopituitarism due TBI and SAH. [less ▲]

One out of four very preterm infants will present with circulatory maladaptation during the first two days of life, with an increased risk of early complications and long term sequelae. Appreciation of those transitional difficulties cannot be limited to blood pressure. Assesment of blood pressure itself must be done in relation with gestational age and birth weight adapted norms. The effects of therapies for low systemic blood flow on blood pressure, organs and cerebral circulations are better understood, but none of them has assessed for mortality or neurodevelopmental outcomes.

Orthostatic hypotension (OH) is defined by a drop in arterial blood pressure (BP) of at least 20 mmHg for systolic BP and 10 mmHg for diastolic BP after standing. Symptoms are generally quite typical, but may also be rather vague. Diagnosis may be easily made by the physician in his/ her office, and confirmed, if necessary, by more sophisticated measurements. Pathophysiology is generally rather complex, but mostly involves a defect in the autonomic nervous system, in its sympathetic component. Failure of peripheral vasoconstriction seems to play a more important role than the defect in reflex tachycardia. Causes of OH are multiples. OH may occur in healthy subjects, when exposed to exceptional circumstances, but is more generally associated with various diseases, either neurological disorders or pathologies characterized by hypovolemia. Medications can also aggravate the risk of OH, among which some antihypertensive or psychotropic agents. Elderly people, especially frailty subjects, are exposed to a high risk of OH, whose origin is often multifactorial, and this complication may have serious medical consequences. [less ▲]

Orthostatic hypotension (OH) is a rather common phenomenon in clinical practice. It may occur in 5-10 % of normal individuals, but its prevalence increases with age and various pathologies, so that it may rise above 35 % in certain subgroups of patients. OH is associated with various comorbidities, in particular cardio-cerebro-vascular accidents and falls (especially in the elderly), and may even increase mortality. It is, however, difficult to determine whether OH is simply a marker of frailty or whether it is really a risk factor. OH treatment involves physical manoeuvres or medications, which aim at inducing a peripheral vasoconstriction (midodrine, etilefrine) or an increase of circulating blood volume (9-alpha-fluohydrocortisone). However, their use should be cautious, because of a risk of arterial hypertension in supine position. [less ▲]

A radioimmunoassay (RIA) for recombinant tilapia growth hormone (GH) was established and validated. The ability of various hypothalamic factors to regulate GH secretion in the tilapia hybrid (Oreochromis niloticus x Oreochromis aureus) was studied. Somatostatin1-14 (SRIF1-14; 10-100 micrograms/kg) was found to reduce circulating GH levels in a dose-dependent manner. SRIF1-14 (0.1-1000 nM) inhibited GH release from perifused pituitary fragments (ED50 0.83 nM). Human growth hormone-releasing hormone fragment 1-29 (hGHRH1-29; 100 micrograms/kg) doubled circulating GH levels and modestly stimulated GH secretion in vitro. Carp growth hormone-releasing hormone (cGHRH) stimulated GH secretion in vitro to a similar degree at the same dose (1 microM). Injection of salmon gonadotropin-releasing hormone (sGnRH) superactive analog (10-100 micrograms/kg) increased plasma GH levels sixfold. sGnRH also stimulated GH release in vitro (ED50 142.56 nM). Dopamine (0.1-10 microM) and the D1 DA receptor agonist SKF 38393 increased GH secretion from perifused pituitary fragments dose-relatedly. Thyrotropin-releasing hormone (TRH) had no effect on GH secretion from perifused pituitary fragments, but increased plasma GH levels, as did bovine thyroid stimulating hormone (bTSH). The increased plasma GH in the bTSH-treated fish coincided with a dramatic increase in T4; however, TRH increased GH without changing T4 levels. T3 increased the synthesis of GH by isolated pituitaries (incorporation of [3H]leucine). SRIF1-14 seems to be a most potent hypothalamic regulator of GH secretion in tilapia; sGnRH and DA both increased GH secretion, although sGnRH elicited considerably greater responses at lower doses. Two forms of GHRH increased GH levels, although the unavailability of the homologous peptide prevented an accurate evaluation of its importance in regulating GH secretion. The thyroid axis (TRH, TSH, and T3) stimulates both synthesis and release of GH, although TRH did not appear to have a direct effect on the level of the pituitary. [less ▲]

We enrolled six patients suffering from refractory chronic cluster headache in a pilot trial of neurostimulation of the ipsilateral ventroposterior hypothalamus using the stereotactic coordinates published previously. After the varying durations needed to determine optimal stimulation parameters and a mean follow-up of 14.5 months, the clinical outcome is excellent in three patients (two are pain-free; one has fewer than three attacks per month), but unsatisfactory in one patient, who only has had transient remissions. Mean voltage is 3.28 V, diplopia being the major factor limiting its increase. When the stimulator was switched off in one pain-free patient, attacks resumed after 3 months until it was turned on again. In one patient the implantation procedure had to be interrupted because of a panic attack with autonomic disturbances. Another patient died from an intracerebral haemorrhage that developed along the lead tract several hours after surgery; there were no other vascular changes on post-mortem examination. After 1 month, the hypothalamic stimulation induced resistance against the attack-triggering agent nitroglycerin and tended to increase pain thresholds at extracephalic, but not at cephalic, sites. It had no detectable effect on neurohypophyseal hormones or melatonin excretion. We conclude that hypothalamic stimulation has remarkable efficacy in most, but not all, patients with treatment-resistant chronic cluster headache. Its efficacy is not due to a simple analgesic effect or to hormonal changes. Intracerebral haemorrhage cannot be neglected in the risk evaluation of the procedure. Whether it might be more prevalent than in deep-brain stimulation for movement disorders remains to be determined. [less ▲]

The Little Fire Ant, Wasmannia auropunctata, is ranked among the World’s 100 worst invasive species. Since the early 90’s, it is officially established in French Polynesia. The Polynesian government actively fights it since 2005, partially through the mapping of the known colonies. By this process, we discovered that the contaminated areas are also sheltering endemic hearths of Florida keratopathy. We studied 24 cases of keratopathy within the mega-colony settled in the Mahina commune’s highs (Tahiti). After control cases search, we pointed that the threatened animals are those living in contact with the ants (К² >12 within studied Pets cases). Apart from this predisposing factor, we did not found any other characteristic facilitating this pathology outbreak. We highlighted: 1) symptoms of acute attack such as blepharospasm and whimpering; 2) Topography of injuries shows that the eye median area is the most affected (p<0,05); 3) The most probable etiologic agent of this pathology is Wasmannia auropunctata.

Introduction The author recalls the setting for the Rorschach test meets the conditions of validity to be interpreted in accordance to the Comprehensive System. Since the work of JE Exner consensus is established to identify two categories of invalid protocols: the protocols collected from subjects who are temporarily in a serious state of disarray for contextual reasons and the brief protocols. Regarding the brief protocols, the rule is clear and precise: research findings indicate that the overwhelming majority of records of less than 14 responses will not have the level of reliability prerequisite to the assumption of interpretive validity. The test will be considered invalid if the subject does not give at least one answer to each of the cards. For the presented protocol, it is not fair to detect any structural and psychopathology data. The author's hypothesis is to propose an unique and phenomenological study of the test and to formulate an hypothesis regarding the psychological functioning of the subject. The subject is a patient of 32 years old showing a paranoid schizophrenic disorder in symptomatic stabilization for six months. The patient receives a treatment with neuroleptics and follows therapy based on knowledge of the disorder and the recognition of associated symptoms. The patient's Rorschach is invalid (less than 14 answers and no response and 3 rejections of cards). Protocol analysis From the 10 responses, each perception is reviewed, either directly or during the inquiry. Finally, each answer was rejected by a perceptual justification that will give "evidence" to challenge the response ("but not a ... because ... ") or by a simple assertion ("because it does not look like", "it cannot be right" or "it's not that"). Cognitive mediation - the process between the information processing and ideation - can be analyzed in depth for this protocol. The cognitive mediation reflects the mental operations involved in the translation or the identification of the data collected. The process requires some reconciliation (mediation) between the image that has been stored and available items from the memory of the individual so as to accomplish the task of responding to the question "What might this be?". In this protocol, the cognitive mediation responds to a simple and repetitive logic which seems to reflect an idiosyncratic psychological functioning. In general, in the Rorschach’s situation, the subject must give a "wrong" answer because the only absolutely correct answer is "the inkblot". The Rorschach’s test requires that the person to "misperceive" the stimulus (to "violate reality"). For the protocol of this study, each response – each "false perception" - is systematically reviewed by the subject and ultimately rejected with contradictory perceptual justification or arguments unsophisticated. Discussion and hypothesis An idiographic hypothesis is formulated by the author from this tendency to systematic doubt. This means identifying, through this subject, the use of a form of "methodical doubt" in the cognitive mediation. This mechanism would fit in a paradoxical context that may reflect the state of the schizophrenic patient in a symptomatic stabilization situation. This hypothesis shows that the stabilization should not be confused with any remission or "cure" (suggesting a return to a previous state to psychosis). If the subject learns to explicitly doubting against ambiguous stimuli, it is hardly possible to tolerate a moderate degree of violation and therefore meet the paradigmatic principle of the Rorschach. Finally, the analysis of the Rorschach’s test gives us an interesting information about symptomatic stabilization situation and residual component of the schizophrenic disorder. These observations appear to be incompatible with homeostatic hypothesis and demonstrate the usefulness of residual schizophrenia diagnosis. The rule of "misperception" if it is tolerable and implicit for the non-psychosis individual, it is intolerable and always explicitly questioned by our schizophrenic patients. The relation between implicit and explicit is a complexed dialectical conflict that seems to characterize the psychological functioning on a continuum showing schizophrenic subject and non-psychosis person.
