CD5 B cells in autoimmune and non immune-mediated thyroid dysfunctions.

In a previous study we demonstrated a significant increase of CD5+ B subset in patients with Graves' disease (GD) compared with normal controls. The aim of this study was to compare the percentage of CD5+ B and CD5- B cells in GD with that in different forms of autoimmune and non immune-mediated thyroid diseases. Seventy-two patients were studied: 28 patients with GD, 20 with silent thyroiditis (ST), 12 with Hashimoto's disease (HD), and 12 subjects affected by hyperthyroidism due to toxic adenoma (TA). Eleven out of 28 patients with GD were also evaluated after six months of methimazole treatment. The study was performed by cytometric analysis. In GD the percentage and the absolute number of CD5+ B cells were significantly increased compared with normal controls (42.5 +/- 18.2% versus 19 +/- 6.3%, p < 0.0001; 142 +/- 153.3/cmm versus 46.9 +/- 22/cmm, p < 0.003, respectively. CD5+ B cells tended to normalise after six months of treatment. In ST the percentage of CD5+ B cells was increased (28.6 +/- 10.2%); conversely the absolute number was in the normal range. Patients affected by HD did not show any significant modification in B cells and their subsets in comparison with controls. In TA, CD5+ B were 7.6 /- 4.4% and 14.3 /- 10.9/cmm. Our results demonstrated a marked increase in both percentage and absolute number of CD5+ cells, only in active GD. The expansion of CD5+ B cells could play a role in the immune imbalance present in this disease.

Low doses of liquorice can induce hypertension encephalopathy.

Prolonged ingestion of liquorice is a well-known cause of hypertension due to hypermineralocorticoidism. We describe 2 cases of hypertension encephalopathy (in addition to the classical symptoms of hypertension, hypokalemia and suppression of the renin-aldosterone system) which resulted in pseudohyperaldosteronism syndrome due to the regular daily intake of low doses of liquorice. Glycyrrhizic acid, a component of liquorice, produces both hypermineralocorticism and the onset of encephalopathy through the inhibition of 11beta-hydroxysteroid dehydrogenase. Hypertension encephalopathy due to the daily intake of low doses of liquorice, however, has not been previously documented. It is proposed that some people could be susceptible to low doses of glycyrrhizic acid because of a 11beta-hydroxysteroid dehydrogenase deficiency.

Hunger sensation in Graves' disease before and after pharmacological therapy.

PURPOSE: Hunger sensation (HS) provides information about the need of eating in order to counterbalance the energy expenditure (EE). HS was, thus, investigated in patients affected by Graves' disease (PAGD), a clinical condition characterized by excessive EE. MATERIALS AND METHODS: Ten newly diagnosed PAGD were investigated before and after therapy. Thirty clinically healthy subjects (CHS) were investigated as controls. The investigated subjects were asked to provide the 24-h profile of their HS by subjectively self-rating (from 1 to 10 hunger units) their orectic perception (OP) at regular intervals of 30 minutes (orexigram). The orexigrams were investigated via the conventional descriptive statistics as well as the Single-Cosinor method. RESULTS: PAGD were found to show a very consistent increase of their HS (hyperorexia), whose day-night variability was, still, the expression of a circadian rhythm, characterized by an elevation in its oscillatory level and extent. Interestingly, the pre-treatment hyperorexia was seen to show a normalization (eurexia) after pharmacological therapy. CONCLUSIONS: According to these results, it can be affirmed that hyperorexia is a clinical sign of Graves' disease, which is obtained via mechanisms of tonic and amplitude modulation of the HS circadian rhythm. Because of the eurexia after remission, it can be argued that the hyperorexia is a theleological response really aimed at increasing food intake in order to counterbalance the excessive EE which characterizes the thyrotoxicosis.

Lipid anomaly in a child with partial duplication 3p.

The authors report a case regarding a 7-year-old girl affected by short height, bone growth delay, lipidic alterations (hypercholesterolemia, hypertriglyceridemia and high apolipoprotein B values) and by a partial duplication of the short arm of the third chromosome: 46,XX, dup(3)(p26-pter). This chromosomal alteration appears "de novo", as the parent's karyotypes are normal and none of the patient's next of kin showed evidence of lipidic anomalies. The patient's short height and slight frontal bossing were the only features that could be described as typical of the dup3p syndrome.

[Atrial stunning and pharmacologic cardioversion in idiopathic atrial fibrillation of recent onset].

BACKGROUND: Normal atrial mechanic function may not return immediately after the successful cardioversion of atrial fibrillation. It has been suggested that the delayed recovery of atrial contraction (atrial stunning) might be due to: 1. the energy delivered during direct current cardioversion 2. the time from the onset of atrial fibrillation 3. the left atrial size 4. the associated cardiac disease. This study evaluates "atrial stunning" in patients pharmacologically treated, with atrial fibrillation of recent onset, normal atrial size and without heart disease. Doppler echocardiography is well suited for assessment of atrial function due to the ability of recording the peak velocity of atrial contraction (A wave). METHODS: Twenty-five patients with no evidence of heart disease and M-mode left atrial dimension less than 40 mm underwent successful pharmacologic cardioversion (pro-paphenon or flecainide 2 mg/kg/10 min) of atrial fibrillation of recent onset (less than 48 hours). After cardioversion an echocardiographic study was performed within 12 hours (ECO 1), on day 3 (ECO 2), on day 12 (ECO 3), and on day 30 (ECO 4). RESULTS: No significant difference of both left atrial size (37 +/- 3.9 mm; 38.22 +/- 3.8 mm; 38.02 +/- 4.7 mm; 38.2 +/- 4.14 mm) and peak E velocity (57.97 +/- 18.3 mm/sec; 59.4 +/- 18.3 mm/sec; 59.0 +/- 16 mm/sec; 59.07 +/- 16.7 mm/sec) was demonstrated among serial echocardiographic evaluations. Both peak A velocity (mm/sec) and E/A ratio were significantly different in ECO 1 (60.29 +/- 12.3-1.0 +/- 0.37) than in ECO 2 (73.1 +/- 10.7, p < 0.005-0.82 +/- 0.27, p < 0.05); no statistical difference was found between ECO 2 and ECO 3 (76.31 +/- 12-0.78 +/- 0.24 mm/sec)--ECO 4 (76.91 +/- 14.8-0.78 +/- 0.21 mm/sec). CONCLUSIONS: This study suggests that patients with atrial fibrillation of recent onset have a delayed recovery of normal atrial systolic function after pharmacologic cardioversion.

Further studies on acid phosphatase in obese subjects.

Low activity genetic variants of acid phosphatase (ACP1) are positively associated with extreme body mass deviations in obese subjects. The same pattern has been found in non-diabetic children, in diabetic pregnant women, and in non-diabetic adult subjects. Low activity variants of ACP1 also show a positive association with family history of obesity, supporting the hypothesis of an enhancing action of these variants on expressivity of obesity.

[Antithyroid antibodies and endemic goiter].

Relationship between thyroid autoantibodies and endemic goiter have been studied in 164 subjects from three different areas of endemic goiter: 91 patients and 31 healthy controls from Central Sardinia, 23 patients from Northern Latium, and 19 patients from Southern Latium. In subjects with endemic goiter from Sardinia higher levels of thyroid autoantibodies were present as compared to the healthy controls; microsomal fraction autoantibodies titer was higher than antithyroglobulin autoantibodies. In subjects from the two other endemic goiter areas the antimicrosomal and antithyroglobulin autoantibodies were absent, with the exception of one patient with basedow's goiter. It is suggested that some of the areas classified as positive for endemic goiter are indeed characterized by an extensive genetic predisposition to lymphocytic chronic thyroiditis complicated by nodular goiter.

[Clinical and CT aspects of muscular dystonias].

Clinical, EMG, genetic and CT investigations were performed on 16 subjects suffering from Torsion Dystonia. We obtained the following results: i) genetically most cases were sporadic, only two could be considered autosomic dominant; ii) one of the pedigrees, with many patients, confirmed that spasmodic torticollis is not a distinct form from that of Dystonia Muscolorum Deformans; the two forms must be included in one disease called "Torsion Dystonia", as maintained by some Authors; iii) we found that the various drugs employed, rarely produced improvement, although benzodiaze4pines have given some benefit; iv) CT findings were not specific, though useful for differential diagnosis.

[Neurological complications in drug dependence with special reference to the development of epileptic syndromes].

33 drug abusers were examined and all of them were addicts to several drugs and always to heroin. Neurological complications occurred rather frequently. One patient had subarachnoid hemorrhage and angiography showed no arteriovenous malformations nor other pathology. Polyneuropathy has been found in one case. 7 patients (21,2%) developed psychotic episodes. Epileptic attacks were found in 5 cases (15,1%). Latency between the onset of drug-abusing and occurrence of the attacks was found to be at least 1 year in two cases and 3 years in the other three. 4 cases suffered from partial complex seizures with secondary generalization and one patient had generalized tonic-clonic attacks. Fits occurred rarely in all cases; one patient had two episodes of partial status. Further research is required because there are few clinical reports in comparison with the experimental ones.

[Epileptic patients: work and entailing risks (author's transl)].

We made a survey of 450 epileptic patients to find out how their disability affected their jobs and what risks were involved. 60% of the patients questioned had jobs. Those who did not work had frequent attacks and neurological and/or psychiatric handicaps. About 50% of the working epileptic patients were self-employed against a figure of 35% for the self-employed population in our region. In 6.6% of the cases, accidents had occurred at work because of attacks. In half of these cases the accident was not serious and in the other of no account. There is little difference between the Italian population in general and the epileptic when we consider the risks involved at work. This may be attributed to the prudence and common sense the patients show in their choice of work (when this is possible) and in the way they perform their work. Italian law on civil disability limits the work for which epileptics may be employed. For this reason they very often hide their illness from their employer and co-workers.

[The problem of private insurance for patients with epilepsy (author's transl)].

324 epileptics were questioned about their approach to private insurance. Only 9,26% of them were covered by a life or accident insurance policy: 3,70% had life insurance, 3,70% accident insurance and 1,86% both. None of the patients had declared his disability to the insurance company. In 6,17% of the 324 epileptic cases an insurance policy had been taken out by their parents. In comparison about 35% of the Italian population in general are insured. A questionnaire was sent to 20 insurance companies; only 5 of them replied, saying that as far as accidents were concerned, they considered epileptics uninsurable. As for life insurance, policies can be contracted at increased premiums, according to the individual case (including the severity of the illness). Physicians must give epileptics fuller information about their insurance plans because, if their illness is detected after an accident, they will find themselves not covered by insurance. Government intervention is called for with the setting-up of special funds for this purpose.

[The driving license and epilepsy (author's transl)].

Italy is one of the few countries in Europe with no legislation specifically concerning driving licenses and epilepsy. We made a survey of 321 epileptics all over 18 years of age; 80,4% of them had epilepsy (temporal lobe). 47,7% of the 321 had a driving license, 2,8% had their license withdrawn because of epilepsy. The frequency of attacks among those with licenses was as follows: 52,9% rarely had attacks (1 every 2 years or even less often), 17,7% had attacks yearly and 29,4% had frequent attacks (1 a month, 1 a week or even daily). About 2% of the patients examined had had accidents because of attacks; none of the accidents were very serious. In spite of the lack of legislation, a high number of patients has driving license. However our investigations have shown that they were careful in their driving and scrupulous about treatment and medical check-ups. The main problem is that epileptics with a driving license may encounter serious difficulties with insurance companies if they have a car accident. It is to be hoped that in Italy appropriate measures are taken parallel to those of other European Countries.

[Institutionalized epileptic patients in the "Marche" region (preliminary data) (author's transl)].

The purpose of this survey was to gather information about long stay epileptic patients in 16 institutions of the "Marche" region. The 203 institutionalized subjects were examined and the information fed into computer. All the patients, in addition to epilepsy, had psychiatric and or neurological handicaps, which were often more disabling than their epilepsy (with difficult social adjustment in most cases). The socio-economic level of the families was usually rather low. Ths survey showed satisfactory as well as unsatisfactory aspects of rehabilitation facilities, equipment, medical and para-medical staff, in these institutions. The deficiencies were mostly caused by the lack of coordination and programming at regional level. Each institution, in effect, acted independently.

[Genetic, polyphysiographic, CT and therapeutic aspects (author's transl)].

Genetic, clinical, polyphysiographic and therapeutical aspects were investigated in a 37 year old patient suffering from: sporadic and localized segmentary myoclonia (present during rest and increasing slightly during movement), cerebellar syndrome, marked hypoacusia, hyper-reflexia of the lower limbs, spike and polyspike EEG discharges and massive myoclonia during photostimulation. A dominant autosomic inheritance of this syndrome was suggested by the occurrence of a more serious and rapid, yet similar, illness in the mother and by EEG alterations in an 8 year old son. The Authors suggest that, from the clinical point of view, they are dealing with an atypical Ramsay-Hunt syndrome (MCD) with signs of Pierre-Marie Heredoataxia. This supports the possibility, however rare, of intermediate forms between MCD and Heredoataxia. The patient underwent polyphysiographic investigations under the following conditions: i) without therapy; ii) with diphenylhydantoin; iii) with phenobarbital; iv) with sodium dipropyl-acetate; v) with clonazepam. The above investigations confirmed the previously described alterations, during wakefulness or sleep, observed in cases of Unverricht-Lundborg syndrome (PME) and Ramsay-Hunt syndrome (MCD). Clonazepam was found to be the most effective drug in attenuating myoclonia, in reducing the EEG spike activity and in reorganizing the phases and cycles of sleep.
