Sex steroids and personality traits in the middle luteal phase of healthy normally menstruating young professional women.

OBJECTIVE: Sex steroids affect human behavior. The aim of the present study was to determine the associations, if any, between the circulating levels of gonadal and adrenal sex steroids in the mid luteal phase (21st day of a normal menstrual cycle, MC) of young professional women and psychometric parameters as assessed by the Minnesota Multiphasic Personality Inventory (MMPI). RESULTS: Our results are as follows: (a) The metabolic product of activated adrenal and gonadal androgens, 3alpha-diolG, was modestly but significantly associated with the social introversion scale (10-SI) (r=0.36, p<0.05), independently accounting for 13% of its variation across participants (R²=0.13, F(1,45)=6.58, p=0.014). (b) Total testosterone was significantly associated with the paranoia scale (6-Pa) (r=0.27, p<0.05). Multiple regression analyses indicated that 10% of the variability in paranoia scores could be independently explained by total testosterone levels (R²=0.10, F(1,57)=6.23, p=0.016). We were unable to find any association between the circulating androgens and scores on the masculinity-femininity scale (Mf). We were also unable to document any association between the weak adrenal androgens DHEA and DHEA-S and depression in contrast to several published reports. (c) Our data suggest a marginally significant association between progesterone and scores on the 7-Pt (obsessive/compulsive/psychasthenia) scale (r=0.27, p<0.05). However, only 7% of the 7-Pt variance was explained by progesterone (R²=0.071, F(1,50)=3.81, p=0.057). CONCLUSIONS: We have found that total testosterone was associated with the paranoia score, the metabolic product of activated androgens, 3alpha-diolG, to social introversion and, finally, progesterone to obsessive-compulsive behavior.

Polymorphisms in AKR1C4 and HSD3B2 and differences in serum DHEAS and progesterone are associated with paranoid ideation during mania or hypomania in bipolar disorder.

Paranoia is commonly a mood-incongruent psychotic symptom of mania which may be related to dopamine dysregulation. Progesterone and its metabolite allopregnanolone (ALLO) have been found in animals to antagonize the effects of dopamine. We therefore examined serum progesterone, its endogenous antagonist DHEAS and polymorphisms of the genes coding for certain steroidogenetic enzymes (AKR1C4, HSD3B2, and SRD5A1) in 64 males and 96 females with bipolar 1 or 2 disorder with or without paranoid ideation during mood elevation. Euthymic morning serum progesterone, DHEAS and cortisol concentrations were measured in males and in premenopausal women who were in follicular phase and not taking oral contraceptives. In women only, SNPs in AKR1C4 reduced the likelihood of having exhibited paranoid ideation by circa 60%. The haplotype of all 4 SNPs in the AKR1C4 gene reduced the risk of exhibiting paranoia by 80% (OR 0.19, 95% CI 0.06-0.61, p=0.05). A history of paranoid ideation was not, however, related to progesterone or DHEAS concentration. Serum DHEAS and progesterone concentrations were lower in men who had shown paranoid ideation during mania/hypomania compared with those who had not (F=7.30, p=0.006) however this was not coupled to polymorphisms in the selected genes. The ancestral G in rs4659174 in HSD3B2 was in men associated with a lower risk of paranoid ideation (likelihood ratio χ(2) 3.97, p=0.046, OR 0.31 (95% CI 0.10-0.96)) but did not correlate with hormone concentrations. Hence, gene variants in the steroidogenetic pathway and steroids concentration differences may be involved in the susceptibility to paranoia during mood elevation.

[Neuropsychiatric symptoms revealing pseudohypoparathyroidism with Fahr's syndrome]. / Manifestations neuropsychiatriques révélant une pseudohypoparathyroïdie avec un syndrome de Fahr.

UNLABELLED: Fahr's syndrome is characterized by the presence of intracerebral, bilateral and symmetrical non-arteriosclerotic calcifications, located in the central grey nuclei. One of its main etiologies is pseudohypoparathyroidism (PHP), due to a resistance to the action of parathormone (PTH) with essentially hypocalcaemia and a normal or a high rate of PTH. CASE REPORT: Mr B.A. is a 36-year-old man, admitted to hospital because of refractory psychotic symptoms associated with alcohol abuse and fits of convulsion, for diagnostic and therapeutic update. Mr B.A. had presented convulsions since the age of 10, without regular medical treatment. He showed a decrease in his school performances and started using alcohol. Since the age of 17, he began expressing delusions of persecution and of enchantment fed by the persistence of the convulsions. He was administered phenobarbital, and classic antipsychotics (haloperidol and levomepromazine) and developed serious extrapyramidal side effects, treated with an anticholinergic (trihexyphenidyl). Evolution was rather disadvantageous: more epileptic fits, exaggeration of tremors; abuse of alcohol and persistence of psychotic symptoms. On admission, psychiatric examination objectified paranoid delusions of being possessed and persecuted by others. Neurological examination revealed the presence of limb tremors, with a positive Froment's sign on the right, and dysarthria. Other than this, the patient was shorter in comparison with his siblings and exhibited bad dentition. A CT brain scan found bilateral, symmetric basal ganglia calcifications, confirmed by MRI, in favour of Fahr's syndrome. Phosphocalcic investigations revealed a low concentration of serum calcium (65 mg/l) and a hyperphosphataemia (60.1mg/l). The blood level of parathyroid hormone was in the upper limit of normal (66 ng/l), and levels of thyroid hormones and thyroid-stimulating hormone were normal. The diagnosis of Fahr's syndrome, revealing a pseudohypoparathyroidism was posed, and the patient was orientated to endocrinology after readjustment in his therapy (sodium valproate and olanzapine). DISCUSSION: About 40% of the patients with Fahr's syndrome are seen with primarily cognitive and other psychiatric findings. For this patient, hypocalcaemia was at the origin of his convulsions, and the use of phenobarbital, known for its hypocalcemiant action, provoked the inverse result. Alcohol drinking also aggravated hypocalcaemia, and maintained the fits. The use of classic antipsychotics and anticholinergic agents, amplified the extrapyramidal signs caused by Fahr's syndrome. Recognizing the origin of the symptoms allowed rethinking the therapeutic strategy according to all these elements. CONCLUSION: Psychiatrists should consider Fahr's syndrome as a differential diagnosis in the evaluation of psychosis associated with convulsions. This case, along with others in the literature, further emphasizes the importance of the role of neuro-imaging and the search for disrupted phosphocalcic metabolism in patients with atypical or refractory psychotic symptoms.

[Lithium and hyperthyroidism]. / Lithium und Hyperthyreose.

The development of hypothyroidism and the forming of a goiter are well-known complications associated with lithium medications. But there are also occasional references to cases of hyperthyroidism in the wake of both continual and of discontinued lithium medication. In the case being reported on here of a lady patient aged 64 and suffering from a toxic adenoma not recognized at the time, thyrotoxicosis accompanied by above-normal FT-3 results and the characteristic clinical symptoms developed when lithium medication was discontinued. Medical literature consulted in the context discussed pharmacological mechanisms which may be responsible for the said complications.

Creatine kinase and aldolase in serum: abnormality common to acute psychoses.

Activity of creatine kinase and aldolase in serum increased in 14 of 16 patients with recent onset of a psychotic reaction, and in five of six patients treated with psychotomimetic drugs. There was either no increase of these enzymes or a slight increase in severely agitated (or depressed) non-psychotic hospitalized patients and chronic psychotic patients. The increase of the enzymes preceded the onset of the acute psychotic symptoms in at least three cases, was highest during the first 2 weeks of a psychotic episode, and sometimes recurred throughout the illness, particularly at times of stress. The creatine kinase in the serum is primarily of the muscle type.
