[Cervical Pyoderma gangrenosum: treatment by plasma exchanges].

The authors report one case of Pyoderma gangrenosum whose unusual cervical localization was particularly bothering. Besides, the patient, an 18-year-old girl, had clinical symptoms of Crohn's disease confirmed by radiological investigations and bowel pathology. A benign monoclonal gammapathy and an auto-immune haemolytic anaemia were also found. After four plasma exchanges Pyoderma healed rapidly, Crohn's disease stabilized and biological abnormalities disappeared. Comments and review of the literature are reported. It appears that such a case is quite exceptional, as far as clinical, biological data and therapy (plasma exchange) are concerned.

[Heredity and prevention of atopy].

Although clinical studies have been supplying strong arguments in favour of a hereditary transmission of atopy for a long time, the latest works have not made it possible yet to specify the biologic support of this heredity. An obvious correlation, especially, has not been demonstrated between, on the one hand, atopic ground and HLA group and, on the other hand, between a high production of total IgE and HLA group. At present, the production of specific IgE only seems to be really subordinated to the HLA system; it is likely to be the expression of complex immunological disorders of a genetic determinism. Various environmental factors will contribute, on this predisposed ground, to the disclosure or to the worsening of the atopy. Some prevention of atopy may be undertaken. Extended breast feeding, eviction of some environmental nuisance and family affective balance thus represent useful preventive measures. The influence of the date of conception and of the pregnancy and delivery conditions does not appear to be insignificant; but, there, the prevention is more difficult to set up. Finally, the counting of the IgE in the cord blood could lead to the detection of high-risk newborns.

The possible reason for serum 3,3'5'-(reverse) triiodothyronine increase in old people.

Healthy subjects aged 70-90 and 20-40 years were investigated for the level of reverse triiodothyronine (rT3). The mean level in 57 old subjects was higher and the triiodothyronine (T3) level lower than in 30 young persons. No negative correlation was observed. A serum T3 elevation caused by liothyronine administration (5-15 micrograms/day for two weeks) was not followed by a change of the mean rT3 level in 12 old subjects. After a single intramuscular thyrotropin (TSH) injection, the rT3 elevation lasted 24h longer in 19 old persons than in the 9 control ones, though the early rT3 response was similar in both groups. Propranolol administration (40 mg t.i.d. for a week) caused a similar rT3 elevation in old persons (n = 18) as in 12 young ones. From the indirect data it is concluded that the serum rT3 elevation in old age is a result of faster peripheral generation and not of increased production in the thyroid gland. The data do not indicate any change of rT3 metabolism. T4-T3 and T4-rT3 conversion are provoked by different enzymes. The elevation of rT3 might be a cause of the observed decrease in peripheral T3 generation in old subjects, acting by an inhibition of the T4-T3 conversion.

[Treatment of tinea microsporum. Metabolic interference between phenobarbital and griseofulvin].

Two epileptic children treated with phenobarbital and suffering from tinea capitis, not responding to a long lasting treatment with Griseofulvin, healed only after phenobarbital has been discontinued. We ascribe our therapeutic problems to the metabolic interference of Griseofulvin with phenobarbital. We have measured the blood concentration of Griseofulvin several times in one of our 2 children and in a control of the same age living in the same dietary conditions and in the same conditions of Griseofulvin intake; these measurements confirm these data. The point of interest of this report is to draw attention on: -the pharmacologic hypotheses put forward to explain this drug interference, -the other factors of a bad therapeutic response to a treatment with Griseofulvin.

[Plasma concentration and systemic effect of betamethasone after intra-articular injection (author's transl)].

Plasma concentrations of betamethasone, cortisol and corticosterone were measured before and after intraarticular injection of a betamethasone-depot preparation (Celestan-Depot) by radioimmuno-assay in 31 patients. Plasma concentration of betamethasone reached its maximum of between of 10 and 17 microgram/dl 30 min after injection. It had fallen to half after 2 hours, and practically to nil from the eighth day onwards. Lowest plasma levels of cortisol and corticosterone occurred after 6--24 hours, returning to the normal range after four days. In nine patients with knee-joint effusion and synovitis the plasma concentration of betamethasone was significantly higher after 24 hours, and cortisol and corticosterone values after 48 hours significantly more suppressed, than in patients without joint effusions and signs of inflammation. The results indicate that plasma concentration of betamethasone and the suppressant effect on the adrenal cortex after intra-articular injection is similar to that after intramuscular applications. Correspondingly, systemic application of the cortisol derivatives can cause significant side effects and be contra-indicated also after intra-articular injection.

[Cefotaxime in septicaemia and severe infections due to multiresistant Gram-negative bacilli (author's transl)].

Cefotaxime was given to 26 patients with serious infections resistant to other antibiotics. 15 patients were suffering from septicaemia due to Gram-negative bacilli, which were caused either by a single organism (13 cases:" of which Serratia in 6, Klebsiella in 3) or by several organisms (2 cases); 7 had upper urinary tract infections (caused by Serratia in 4 patients), and 6 had miscellaneous infections (two of these were purulent post-operative meningitis). The pathogens were usually resistant to ampicillin and cephalothin. Cefotaxime was administered at a daily dose of 3 g in 22 patients, irrespective of the renal function, and of 6 g in 4 patients (2 meningitis). Treatment included an aminoglycoside in 12 cases. The efficacy of cefotaxime was very satisfactory in 23 of the 26 patients.

[Frequency and semeiological evolution of epileptic seizures occurring between 40 and 65 years of age (author's transl)].

458 patients who had their first epileptic fit between the ages of 40 and 65 are classified into 5 groups according to the seizure symptomatology: when the symptomatology remains unchanged, the frequency of fits is less than 1 per month in 84% of generalized fits and more than 1 per month in 52% of focal fits. When the symptomatology changes, the frequency of fits is less than 1 per month when the inaugural fit is generalized (23 out of 27) and more than 1 per month when the inaugural fit is focal (15 out of 21). Modifications of the symptomatology correlate positively with a prevalence of tumor aetiology. Primary generalized epilepsies are rare (4.4%). Non-specific secondary generalized epilepsies (including vascular, metabolic or toxic encephalopathies) account for 24.4% of the cases. Focal epilepsies are the most common form (40.7%), elementary fits being four times more frequent than complex fits.

Ticrynafen-induced acute renal failure.

Two cases of acute renal failure associated with ticrynafen administration are reported. Both patients had received hydrochlorothiazide prior to the institution of ticrynafen therapy and were mildly hyperuricemic. Flank pain, oliguria, and azotemia developed after the institution of ticrynafen in both cases. Clinical and laboratory features were consistent with acute uric acid nephropathy in both patients. In addition, a newly formed collection of radiolucent material was found by intravenous urography in the renal pelvis of one of the patients. Both patients were treated with intravenous fluids and sodium bicarbonate. One of the patients received allopurinol as well. Complete recovery of renal function was observed in both patients. Ticrynafen-induced hyperuricosuria in these previously volume-depleted and hyperuricemic subjects is felt to have been responsible for intrarenal and extrarenal deposition of uric acid in our patients.
