Growth factors and neurotrophins in patients with stress-related exhaustion disorder.

Growth factors, such as vascular endothelial growth factor (VEGF) and epidermal growth factor (EGF), and neurotrophic factors, including brain-derived neurotophic factor (BDNF), have attracted attention in studies of the biological effects of long-term stress exposure due to their neuroprotective roles. This study investigated whether circulating levels of EGF, VEGF and BDNF were altered in individuals with stress-related exhaustion disorder. Forty patients diagnosed with exhaustion disorder and 40 healthy subjects (50% women) provided fasting blood samples for analysis of EGF, VEGF, and BDNF in plasma. We found significantly lower levels of EGF, VEGF, and BDNF in patients with ED compared to healthy controls. This pattern was seen in both male and female patients. Given the important roles of BDNF and VEGF for brain plasticity and neurogenesis, decreased levels after long-term stress exposure could indicate increased risk of neuronal damage and cognitive impairments in this patient group.

[Peculiarities of the psychic state and quality of life in patients with duodenal ulcer in the context of chronomedicine].

Most clinicians consider duodenum ulcer as a psychosomatic disease. Objective: To show the interdependence of this condition and mental disorders and their relation to disturbances of melatonin production . Materials and Methods: 15 patients with seasonal DU and 15 healthy subjects of the control group were examined during 3 years using laboratory, endoscopic, and standard psychodiagnostic methods. Results. It was found that all patients with exacerbation of DU experienced enhanced anxiety, reduced background mood, and impaired quality of life based on general health and mental health scoring scales. The circadian rhythm of melatonin production was markedly distorted throughout the observation period but especially during exacerbations of the disease. Conclusions. The results indicate a high degree of correlation between DU and mental disorders caused by impaired production of melatonin. It suggests common etiological mechanisms of DU and psychosomatic symptom complex.

Posttraumatic oxytocin dysregulation: is it a link among posttraumatic self disorders, posttraumatic stress disorder, and pelvic visceral dysregulation conditions in women?

This article explicates a theory that oxytocin, a sexually dimorphic neurotransmitter and paracrine hormone, is a plausible mechanism linking early relational trauma with posttraumatic self disorders (e.g., dissociation, somatization, and interpersonal sensitivity), posttraumatic stress disorder, and pelvic visceral dysregulation disorders (e.g., irritable bowel syndrome, chronic pelvic pain, interstitial cystitis, and hyperemesis gravidarum). This posttraumatic oxytocin dysregulation disorders theory is consistent with the historical and contemporary literature. It integrates attention to psychological and physical comorbidities and could account for the increased incidence of these disorders among females. Specific propositions are explored in data from studies of traumatic stress and women's health.

The role of carbon dioxide (and intracellular pH) in the pathomechanism of several mental disorders. Are the diseases of civilization caused by learnt behaviour, not the stress itself?

The role of carbon dioxide (CO2) is underestimated in the pathomechanism of neuropsychiatric disorders, though it is an important link between psyche and corpus. The actual spiritual status also influences respiration (we start breathing rarely, frequently, irregularly, etc.) causing pH alteration in the organism; on the other hand the actual cytosolic pH of neurons is one of the main modifiers of Ca2+-conductance, hence breathing directly, quickly, and effectively influences the second messenger system through Ca2+-currents. (Decreasing pCO2 turns pH into alkalic direction, augments psychic arousal, while increasing pCO2 turns pH acidic, diminishes arousal.) One of the most important homeostatic function is to maintain or restore the permanence of H+-concentration, hence the alteration of CO2 level starts cascades of contraregulation. However it can be proved that there is no perfect compensation, therefore compensational mechanisms may generate psychosomatic disorders causing secondary alterations in the "milieu interieur". Authors discuss the special physico-chemical features of CO2, the laws of interweaving alterations of pCO2 and catecholamine levels (their feedback mechanism), the role of acute and chronic hypocapnia in several hyperarousal disorders (delirium, panic disorder, hyperventilation syndrome, generalized anxiety disorder, bipolar disorder), the role of "locus minoris resistentiae" in the pathomechanism of psychosomatic disorders. It is supposed that the diseases of civilization are caused not by the stress itself but the lack of human instinctive reaction to it, and this would cause long-lasting CO2 alteration. Increased brain-pCO2, acidic cytosol pH and/or increased basal cytosolic Ca2+ level diminish inward Ca2+-current into cytosol, decrease arousal--they may cause dysthymia or depression. This state usually co-exists with ATP-deficiency and decreased cytosolic Mg2+ content. This energetical- and ion-constellation is also typical of ageing-associated and chronic organic disorders. It is the most important link between depression and organic disorders (e.g. coronary heart disease). The above-mentioned model is supported by the fact that H+ and/or Ca2+ metabolism is affected by several drugs (catecholemines, serotonin, lithium, triaecetyluridine, thyroxine) and sleep deprivation, they act for the logically right direction.

Endocrine profiles and neuropsychologic correlates of functional hypothalamic amenorrhea in adolescents.

OBJECTIVE: To determine trigger factors and neuropsychologic correlates of functional hypothalamic amenorrhea (FHA) in adolescence and to evaluate the correlations with the endocrine-metabolic profile. DESIGN: Cross-sectional comparison of adolescents with FHA and eumenorrheic controls SETTING: Academic medical institution PATIENT(S): Twenty adolescent girls with FHA (aged <18 years) and 20 normal cycling girls INTERVENTION(S): All subjects underwent endocrine-gynecologic (hormone) and neuropsychiatric (tests and interview) investigations. A separate semistructured interview was also used to investigate parents. MAIN OUTCOME MEASURE(S): Gonadotropins, leptin, prolactin, androgens, estrogens, cortisol, carrier proteins (SHBG, insulin-like growth factor-binding protein 1), and metabolic parameters (insulin, insulin-like growth factor 1, thyroid hormones) were assayed in FHA and control subjects. All girls were evaluated using a test for depression, a test for disordered eating, and a psychodynamic semistructured interview. RESULT(S): Adolescents with FHA showed a particular susceptibility to common life events, restrictive disordered eating, depressive traits, and psychosomatic disorders. The endocrine-metabolic profile was strictly correlated to the severity of the psychopathology. CONCLUSION(S): Functional hypothalamic amenorrhea in adolescence is due to a particular neuropsychologic vulnerability to stress, probably related to familial relationship styles, expressed by a proportional endocrine impairment.

[Psychoendocrinology of menopause]. / A menopauza pszichoendokrinológiája.

The possible role of of the marked changes in the regulation of female sex hormones has been implicated in the higher prevalence rate of anxiety and affective disorders in women. There is no evidence, however, for a direct relationship between specific hormone alterations and psychiatric, nosologic entities in the critical periods (premenstrual, postpartum, menopausal). The menopausal psychosyndrome can develop as a result of a chain reaction triggered by the fairly universal and specific vasomotor symptoms: hot flushes and night sweats. The hormone substitution therapy of menopause may have a prompt effect both on the somatic and psychic symptoms, by suspending the domino effect. In addition to that oestrogen has some activating and mood elevating effect, while progesteron can reduce anxiety and related symptoms.

[Changes in the degree of oxygenation of gastric mucosa before and after the operation of creating a small stomach in patients with the extreme degree of alimentary-constitutional obesity]. / Izmeneniia urovnei oksigenatsii slizistoi obolochki zheludka do i posle operatsii formirovaniia malogo zheludka u bol'nykh s krainymi stepeniami alimentarno-konstitutsional'nogo ozhireniia.

The authors examined 131 patients with alimentary-constitutional obesity of Degrees III-IV before and after operation for "small stomach" formation. All patients underwent pre- and post-operative endoscopy of the esophagus, stomach and duodenum. The level of gastric mucosa oxygenation was measured in 50 patients before and in various periods after surgery. For this purpose the authors suggested an original endoscopic +spectrum analyzer and a method for determining the level of oxygenation of the mucosa of the organ. The level of gastric mucosa oxygenation was significantly lower in patients with obesity than in healthy individuals of the control group. After the operation the oxygenation level increased significantly, which was connected with an altered diet regimen, reduced amount of the ingested food, loss of weight, and improved microcirculation in the mucous membrane of the organs of the alimentary tract. The authors emphasize in particular the absence of blood supply disorders at the site of application of a synthetic fluoronlavsan band (in the region of the anastomosis), which is among the indices of the physiological property of this method for surgical treatment of patients with alimentary-constitutional obesity.
