[Unexplained prolonged fever and inflammatory syndromes. Diagnostic value of abdominal X-ray computed tomography. Randomized prospective study of 36 cases].

A randomized study was carried out in 36 patients to determine the diagnostic value of abdominal computerized tomography (CT) in protracted fever of obscure origin and/or unexplained inflammatory syndromes. There were no clinical or biological signs pointing to a diagnosis, and 55% of the patients had already been unsuccessfully explored in other hospital departments. CT was performed initially in group I patients and after some of 56 predetermined conventional examinations (including 20 considered "invasive") carried out in a definite order in group II patients. An early diagnosis could be made within 2 months in 17 patients (47%): 7 in group E and 10 in group II. The underlying disease was diagnosed in 4 cases in group I and 1 case in group II (where 4 other cases could have been diagnosed, had CT been performed earlier); the difference was not significant. Nor was there any difference between the two groups in the number of examinations performed, the cost of investigation and the duration of stay in hospital. However, a number of reasons are in favour of early CT examination in protracted fever: the so-called "invasive" explorations were uncomplicated in group I and complicated in 2 patients of group II; following randomization, a diagnosis was made by CT within less than 3 days in the 4 patients of group I, and there were neither false-positive nor false-negative results of CT. If CT had been performed early in all patients, 9 diagnoses would have been made, representing 25% of the cases or 1/2 of early diagnoses. Abdominal CT proved unable to establish the 10 late diagnoses (i.e. after a mean delay of 18 months).

[Psychic disorders in systemic lupus erythematosus. Prospective study of 35 cases].

In the prospective study reported, 35 patients with systemic lupus erythematosus underwent thorough psychiatric examination. They were divided into three groups according to whether their psychiatric symptoms were acute (10 patients), subacute (9 patients) or non-existent (16 patients). Particular attention was paid to such factors as obstetrical events (pregnancy, spontaneous or induced abortion), history of psychiatric disorders, emotional traumas and treatment with corticosteroids. The overall incidence of psychiatric symptoms was high (54%), mainly due to isolated depressive states (37%). The only significant contributing factors were a personal history of psychiatric disorders (p = 0.001) and emotional traumas (p = 0.0004). There was no difference between the three groups as regards the distribution, dosage and duration of corticosteroid therapy.

[Periarteritis nodosa: clinical and therapeutic study of 126 patients followed-up during 23 years].

A hundred and twenty-six patients with systemic polyarteritis nodosa (PN) were studied over a 23 year period. The clinical symptoms and paraclinical data of PN are reviewed, and the results obtained by the different therapeutic approaches used during this period are presented: steroids alone and then associated with immunosuppressors and, in the most recent cases, associated with plasma exchange. The actuarial survival of patients in this retrospective and unrandomised series was comparable whether steroids were used alone or with immunosuppressors. The different therapeutic approaches in PAN are discussed especially with respect to the role of immunosuppressor therapy and plasma exchange.

[Corticotherapy and surgery. Apropos of 73 cases].

The authors reviewed the outcome of 73 operations performed on 60 patients on long-term steroid therapy: Eighteen operations were carried out for gastro-intestinal perforation but the causal role of steroid therapy was only established in 6 cases (4 gastric and 2 colonic perforations). In the other 12 cases there was intercurrent pathology or a recrudescence of the underlying disease process. More selective indications for steroid therapy and the protective action of new drugs on the gastro-intestinal mucosa are probably responsible for the low incidence of iatrogenic complications compared with previously published series. However, steroid therapy did affect the postoperative course: the risk of infection was 20 to 30 p. 100 higher than normal, very common after emergency surgery (75 p. 100) and a major cause of mortality (60 p. 100); the risk seems to be high when the steroid dose exceeds 0.5 mg/kg/day, the disunion of an anastomosis was observed in 6 cases, including 5 "dirty" operations with a mortality of 60 p. 100, healing was slow: 2 cases of evisceration and 2 of abdominal hernia were observed. It was not possible to assess the threshold dose of steroids with regards to this complication, metabolic complications, especially adrenal failure were much less common. Of the diseases requiring steroid therapy the problem of angiitis seemed particularly prominent. Although the prognosis of the intercurrent surgical condition was not aggravated; mortality from a relapse of the angiitis was nearly 100 p. 100. Therefore, medical control of the relapse would seem to be the first priority and should be taken into account when assessing the surgical indications.

[Fasciolar hepatic abscesses: value of hepatic ultrasonography. Apropos of 3 cases].

Hepatic abscess is a rare complication of fasciolasis. The ultrasonographic appearances of these abscesses are not well known. The finding of nodular echodense images in the hepatic parenchyma may cause diagnostic confusion. We report three cases in which abdominal ultrasonography demonstrated hepatic abscesses complicating fascioliasis. Follow-up examination showed regression of these lesions after treatment.

[Association of Horton's disease and periarteritis nodosa. Apropos of 3 cases].

Three cases of giant cell arteritis associated with periarteritis nodosa are reported. A review of the literature showed 16 similar reports. Giant cell arteritis features in temporal arteries were associated with periarteritis features in visceral or peripheral arteries in 5 cases only. Association of these two conditions seems to be uncommon and may be coincidental but does not justify including giant cell arteritis within the group of necrotizing angiitis. Awareness of this association nevertheless has practical implications as these cases should be treated as PAN patients.

[Treatment of human brucellosis with rifampicin].

Rifampin, which exhibits good intracellular diffusion and in vitro bactericidal activity on brucella, is effective in experimental brucellosis in mice, without selection of resistant strains. It was therefore legitimate to use rifampin in man since conventional treatment of acute brucellosis is followed by recurrence in 15% (tetracycline alone) or 3.7% (streptomycin-tetracycline combination) of cases. Rifampin was given to 13 patients with brucellosis (acute brucellosis in 8, osteoarticular brucellosis in 3 and chronic brucellosis in 2). Rifampin was given as sole therapy in a daily dosage of 600 to 1 200 mg. A tetracycline was subsequently needed in three cases, in combination with rifampin in two, and as replacement therapy in one. Treatment lasted 20 to 60 days in acute brucellosis and 2 to 15 months in other forms. Only one failure was recorded among the 11 cases of acute or localized brucellosis. Conversely, effectiveness of rifampin proved incomplete (1 case) or null (1 case) in chronic forms. The satisfactory effectiveness of rifampin is confirmed by a review of the literature which found 17 reports addressing the subject. These include 324 cases of brucellosis treated by rifampin, as sole therapy in 255 patients, with only 24 failures ascribable to faulty dosage. Indeed, rifampin must be given for at least 30 days, in a minimal daily dosage of 600 mg or 10 mg per kg, in a single dose. Cotrimoxazole is an antagonist and should not be associated with rifampin. Conversely, tetracyclines are synergistic and their association, which is useless in acute brucellosis, is helpful in localized and chronic forms.

The management of thirty immunocompromised patients with tuberculosis.

Between 1978 and 1981, 30 of 870 bacteriologically confirmed cases of tuberculosis occurred in immunocompromised hosts. One year after the diagnosis, 11 patients were dead, only 2 of them of tuberculosis. In the other 19 patients, the course of tuberculosis under standard chemotherapy was the same as in nonimmunocompromised hosts. Among the 24 patients still alive more than 2 months after the diagnosis of tuberculosis, the treatment of the underlying disease was changed in 14 patients to avoid worsening of the course of tuberculosis; 5 patients died and 4 kidney transplant carriers rejected their transplants. The treatment of the underlying disease was not changed in 10 patients: all of these remained alive 1 yr later, and 2 were kidney transplant carriers who did not reject their transplants. We conclude that the clinical response of the immunocompromised tuberculous host was good and that treatment of the underlying disease should not be modified.

[Long-term development of eosinophilic fasciitis. Study of 11 cases].

The long-term outcome of eosinophilic fasciitis (EF) described for the first time by Shulman in 1974 remains unclear. Its exact pathological classification is still contested. We reviewed 11 cases selected exclusively on their initial symptoms being compatible with EF. The outcome of the cutaneous lesions, the investigations of possible visceral involvement were analysed with a follow-up of 1 to 9.5 years (average 4.8 years). Regression of the cutaneous infiltration was complete in 5 cases and partial in 3 cases. No regression was observed in 3 cases. Steroid therapy was given in 10 patients: objective improvement was observed in 5 patients. There was no improvement in the other 5 cases. Ungual capillaroscopy was performed in 9 patients and showed none of the characteristic capillary changes of scleroderma. These results suggest that the prognosis and outcome of EF justify its distinction from systemic scleroderma. The effects of steroid therapy on the cutaneous lesions are very variable.

[Ischemic accidents of the lower limbs with preservation of the peripheral pulse after arteriography (3 cases )].

Marked ischemia of the lower limbs and abdomen, with conservation of peripheral pulses, was noted several hours after arteriography in 3 patients. The origin of the lesion was due to migration of microemboli (cholesterol crystals) in one patient, but was conjectural in the other two cases. Possible etiologies include a chemotoxic effect of the contrast medium used, as well as the action of other factors (sterilization of materials), and the arteriographic technique applied (reflux technique in two cases).

[Splenic involvement in infectious endocarditis. 5 clinical cases and 78 necropsies].

Splenic involvement is a classical complication of infective endocarditis (IE). Clinical manifestations are rare, 5 out of 100 IE: unexpected rupture (1 case), abscess causing reinfection (2 cases), pseudo-tumour (1 case) and terminal infarction (1 case). In addition to a review of the literature, a post mortem histological study of the spleen of 78 cases of IE was undertaken. Splenic involvement did not seem to be the direct cause of death. Three types of lesions which may or may not be associated were observed: congestive inflammatory lesions, infarction (48 p. 100), abscess (6 p. 100). Splenic infarction usually results in scarring but may progress to abscess formation. Rupture was not observed in this autopsy series. Although splenic involvement is common at post mortem it gives rise to few symptoms. Persistant pyrexia and the appearance of local signs should lead to investigation of splenic complications and eventually, to surgical ablation.

[Value of plasma exchange in necrotizing angeitis. 11 cases].

Plasma exchanges proved useful in a series of 11 patients with necrotizing angeitis resistant to conventional treatment (corticosteroids alone in 6 cases and combined with cyclophosphamide in 5 cases). Among the 9 patients alive after 18 months' follow-up, 5 were in remission without treatment. The only disturbing complication of plasma exchanges was hepatitis B in 3 of the 4 survivors who received frozen fresh plasma as substitute. It is suggested that these immuno-compromized patients should receive diluted albumin instead of fresh frozen plasma.
