Correlates of somatic causal attributions in primary care patients with fatigue.

Researchers in the field of chronic fatigue in tertiary care found that patients' somatic (e.g. viral) explanations for their condition may lead to chronicity of symptoms. We studied the influence of a somatic attributional bias on outcome and reported symptoms in primary care patients with fatigue. We compared fatigue scores on a specific scale, and number of presented symptoms, in two groups of primary care patients with 'functional' fatigue: 75 with a high score on the somatic subscale of the Fatigue Attribution Scale (S-FAS), and 95 with a low score on the S-FAS. At the index visit, patients with low and high scores on the S-FAS were not different for age, sex, fatigue scores, and levels of depressive symptoms. Patients with high scores on the S-FAS presented significantly more somatic and psychological symptoms-a total of 36 symptoms for 24 patients (25.3%) in the low-score group, and a total of 52 symptoms for 31 patients (41.3%) in the high-score group. Forty-two days later, at the follow-up visit, the fatigue scores were similar in both groups. In primary care patients with fatigue not due to somatic illness or major depression, the tendency to attribute fatigue to somatic causes is not associated with a worse outcome, but with a higher number of reported symptoms.

[Multiple endocrine neoplasia type 1. Digestive hormones in the screening].

Detection of subjects from a multiple endocrine neoplasia type 1 family must rest on clinical, biochemical and radiological data, since study of the genome is unable to detect these subjects. In the new family described here, 6 out of the 14 subjects explored were affected. One had a confirmed pancreatic endocrine tumour and in 3 others a pancreatic endocrine tumour was highly probable, since insulin and glucagon levels, as well as ultrasonic exploration of the pancreas were pathological. Measurements of gastrointestinal hormones gave normal results in all cases. We conclude that to detect this endocrine neoplasia in subjects at risk it seems necessary to measure plasma insulin levels and perform an abdominal ultrasonography.

[Systemic mastocytosis: incidence and risks of vasomotor seizures].

We report on 9 cases of systemic mastocytosis which underline the frequency and the potential severity of this disease. All patients had intercritical signs (usually urticaria). Seven patients had also typical crises with flush and vascular collapses are observed together, doctors should measure histamine blood level and perform correct biopsy.

[Contribution of chemiluminescence for determination of low value TSH in patients with dysthyroidism during negative TRH test].

TSH values performed by immunoradiometric method were compared with chemiluminescent method in 28 hyperthyroid patients with negative TRH-test. This last method gives a better sensitivity (0.020 mUI/L vs. 0.050 mUI/L) and reproducibility (5% V.C. vs. 40%). The measure of undetectable TSH by immunoradiometric assay becomes possible with chemiluminescence. Due to this increase of sensitivity, the TRH-test needs to be reconsidered and allows to discriminate various degrees of TSH suppression.

[Eosinophilic ascites. 2 new case reports].

Two new cases of eosinophilic ascites and a brief review of 40 cases found in the literature are presented. In three quarters of the cases eosinophilic ascites affects women aged 40 years on average. Because the patients present with a history of allergy (55%), blood hypereosinophilia (69%), associated pleural effusion (11%), gastrointestinal disorders and, above all, eosinophilic infiltrations in the walls of the digestive tract or the serous membranes (63%), this pathology may be regarded as a clinical form or eosinophilic gastroenteritis. The outcome is favourable in 90% of the cases; relapses occur in 26%. Is eosinophilic gastroenteritis and independent pathological entity, or should it be considered a minor clinical form of Chusid's idiopathic hypereosinophilic syndrome? The lack of decisive arguments precludes a firm conclusion.

[Facial hemiatrophy, homolateral cervical linear scleroderma and thyroid disease].

A case of facial hemiatrophy and homolateral cervical band of scleroderma, complicated by hypothyroidism is reported. This case raises two problems: one is the problem of distinction between Romberg's disease and facial hemiatrophy due to a genuine localized scleroderma; the other concerns the relationship between localized scleroderma and dysthyroidism. The generalized scleroderma-dysthyroidism association has now been recognized, but the coexistence of thyroid disease and localized scleroderma has not yet been reported. Several pathogenetic hypotheses on this association are discussed.

[Acute lupus erythematosus disseminatus in adults: clinical aspects & course].

Acute systemic lupus erythematosus (SLE) is characterized by a variety of manifestations and by the almost constant presence of anti-nuclear antibodies. In order to distinguish it from other systemic diseases, eleven diagnostic criteria have been laid down, four of which at least must be present. In 50 p. 100 of the cases the disease is revealed by a non-destructive inflammatory polyarthritis which is highly suggestive when associated with a "butterfly" facial erythema. The main prognostic criteria are renal lesions and their histological type. Nervous system involvement seems to be less frequent and less severe nowadays, but it may leave sequelae. Pleuropericarditis and vascular thrombosis are commonly part of the clinical set up. Antinuclear antibodies are detected by immunofluorescence in more than 95 p. 100 of the patients, but they are not specific to SLE. Their absence in the initial phase of the disease may throw doubts on the diagnosis. Antibodies to DNA and Sm are more specific but inconstant. SLE is a chronic disease with intermittent flare-ups: 30 p. 100 of the patients may hope for a prolonged complete remission. At present, the survival rate at 10 and 20 years is higher than 80 p. 100 and 70 p. 100 respectively at the cost of a very close supervision but also of iatrogenic complications in increasing numbers.

Rapid escape of cortisol from suppression in response to i.v. dexamethasone in anorexia nervosa.

The suppressive effect of dexamethasone (Dex) on plasma cortisol and beta-lipotrophin (beta LPH) was investigated in patients with anorexia nervosa. Dex was given either orally, 1 mg at 2400 h, with blood sampling at 0800 h on the days before and after Dex, or by i.v. infusion starting at 1100 h (1 mg/h) for 4 h with sampling at 0800, 1100, 1500, 2000 and 2400 h and at 0800 h the following day. The plasma cortisol and beta LPH levels during oral or i.v. Dex administration were compared between patients and normally menstruating women of normal weight. The results showed that Dex administration depressed cortisol significantly (P less than 0.0001) during oral or i.v. infusion in most patients, without, however, suppressing it entirely as is the case in normal women. Moreover, during i.v. Dex infusion, the concentrations of cortisol escaped suppression and were higher than in normal women (less than 50 nmol/l) by 0800 h on the day following infusion. In the patients who were reinvestigated after re-feeding and weight gain (n = 9), a normal suppression of cortisol in response to i.v. Dex infusion was observed in only five cases and a slight failure to suppress, although concentrations were lower than before refeeding, was still evident in four. We concluded that, in anorexia nervosa, cortisol concentration rapidly escapes suppression by Dex administration, and that this escape is not related to the degree of starvation.

[Eye manifestations of Horton's disease].

Ocular complications occurring in temporal arteritis are of different severities. These manifestations of the disease occurred in a population of 57 patients with diagnosis of temporal arteritis, in 16 of them (28%). The diagnosis was suggested by finding an inflammatory syndrome (high erythrocyte sedimentation rate) and confirmed by temporal artery biopsy. In making this diagnosis, it was helpful to find a history of characteristic temporal headaches, neckache, jaw claudication, fever and malaise or weight loss in addition to polymyalgia and polyarthralgia. 6 patients presented with diplopia and different ocular muscle or nerve palsies. The 10 others came for sudden loss of vision due to ischemic anterior or posterior neuropathy and in one case, central artery obliteration. Prompt treatment with steroids gave good results on oculomotor troubles and in preventing the risk of involvement of the fellow eye. But loss of vision did not regress with this treatment. That means the importance in making this diagnosis and starting very promptly this treatment.

[Scleroderma and thyroid diseases].

The authors report a prospective study of the thyroid function of 18 consecutive patients with systemic scleroderma and 7 patients with morphea. A history was taken and patients were examined for thyroid disease. The patients were tested for free thyroxin, TSH, cholesterolemia, circulating TeBG, anti-microsomial and anti-thyroglobulin antibodies and had a TRH test. The incidence of thyroid diseases was correlated with an age and sex-matched control population consisting of 2,534 subjects of the Loire department. None of the patients with morphea had a history of thyroid pathology and the thyroid screenings were within normal limits. A familial history of thyroid disease was found in 7 out of 18 patients with systemic scleroderma, and 8 out of 18 patients had a thyreopathy (one Hashimoto's disease, one Graves' disease, one toxic adenoma, one hypothyroidism, two euthyroid goiters, two nodular thyroids). The TRH test only revealed a toxic adenoma. A thyroid disease preceded systemic scleroderma in 5 out of 18 cases with delays ranging from 1 to 38 years. In 3 cases, the thyroid disease occurred within two years after the onset of systemic scleroderma. The prevalence of thyroid disease was significantly higher than in a comparable population sample of subjects from the same geographic region (p less than 0.01). The authors review the literature and discuss the physiopathologic relationships between the two clinical entities. The authors suggest to perform a thyroid screening (ultrasensitive TSH assay) on all patients with systemic sclerosis and especially on those whose clinical follow-up is atypical and on those with a familial and/or personal history of thyroid disease.
