[Pleuropulmonary manifestations of systemic lupus erythematosus].

Pleuro-pulmonary manifestations are frequent in systemic lupus erythematosus (SLE), being found in 40 to 70% of patients with this disease. However, these manifestations can be attributed to SLE only when other pathologies, and notably infections, have been excluded. The truly SLE-related pleuro-pulmonary manifestations can be divided into five types: pleurisy, interstitial pneumonia, lupus pneumonia and two new entities: diffuse pulmonary haemorrhage and pulmonary arterial hypertension. The most frequent manifestation, pleurisy, only requires symptomatic treatment combined with non-steroidal anti-inflammatory agents. Corticosteroids are seldom necessary, but they must be used in lupus pneumonia or in diffuse interstitial pneumonia, owing to the severity and potentially poor prognosis of these two manifestations. Pulmonary haemorrhage is a serious and probably underestimated manifestation; it is diagnosed by bronchoalveolar lavage which also enables other causes, in particular infections, to be excluded. As soon as the aetiological diagnosis is made, high-dose corticosteroid therapy, usually combined with immunosuppressants, is mandatory. Pulmonary arterial hypertension is a classical, but hitherto unrecognized manifestation of SLE which benefits from new exploratory techniques, such as doppler-ultrasonography. At present, its diagnosis rests on data supplied by cardiac catheterization which is generally performed too late, making it irreversible and resistant to all treatments. Some of these pleuro-pulmonary manifestations are probably underestimated and they require new methods of investigation, such as bronchoalveolar lavage or doppler-ultrasonography, resulting in earlier diagnosis and treatment at an accessible stage.

[Wegener's granulomatosis disclosed by clinical symptoms of Horton's disease].

In a series of 60 patients with Wegener's granulomatosis, 2 had initially presented with clinical signs suggestive of temporal arteritis. One of these two patients was a 69-year old woman suffering from inflammatory pain in the shoulders, wrists and knees, myalgias in the lower limbs and intermittent jaw claudication. The other patient was a 60-year old man with febrile polyarthritis predominantly affecting the knees and shoulders, and hyperaesthesia of the scalp. In both cases biopsy of the temporal artery gave negative results. Corticosteroids provided a dramatic improvement, but a relapse corrected the diagnosis. Three similar cases have been reported, but only one had a histological lesion of the temporal artery. Cases of temporal arteritis associated with pulmonary granulomatosis raise the problem of classification with localized Wegener's disease. An initial presentation suggestive of temporal arteritis may hide other systemic diseases, notably rheumatoid arthritis, periarteritis nodosa or Chug and Strauss angitis; Wegener's granulomatosis must be added to this list.

[Coccygodynia disclosing Tarlov's cysts].

In a 63-year old male patient coccygodynia, initially isolated then complicated by incomplete cauda equina syndrome, could be attributed to large perineurel meningeal cysts on the sacral nerve roots. The diagnosis was suspected at computerized tomography and nuclear magnetic resonance and confirmed by sacculoradiculography. Intradural injections of corticosteroids provided lasting pain relief. Arachnoid cysts are often asymptomatic, by they may be responsible for coccygodynia and/or incomplete cauda equina syndrome. Their presence is suggested by the characteristics of the symptoms which are paroxysmal, exacerbated in standing position, relieved in dorsal position and revived by percussing the sacrum. Treatment is medical in most cases. The decision to operate depends on the persistence and intensity of pain and on whether signs of neurological defecit are present.

[Fenofibrate induced polymyositis].

In a 65-year old man complaining of myalgias and loss of muscular strength, the creatine phosphokinase level was found to be 35 times higher than normal values. The electromyogram was of the diffuse myogenic type. Muscle biopsy showed necrotic lesions of the muscle fibres associated with perivascular infiltrates of mononuclear cells, leading to the diagnosis of polymyositis. This patient had been treated for 10 years with fenofibrate for hyperlipidaemia; during the last 32 months he had taken this drug in doses of 600 mg per day. Eight days after fenofibrate was discontinued, all clinical and laboratory abnormalities had disappeared. A reintroduction test performed 6 weeks later raised the creatine phosphokinase level up to 43 times the normal value. Withdrawal of fenofibrate therapy resulted in rapid and lasting recovery. This case shows that fenofibrate should be added to the list of drugs that are responsible for iatrogenic polymyositis.

[A diagnosis to consider: insufficiency fracture of the sacrum].

The authors report a case of insufficiency fracture of the sacrum in an 81-year old woman. The fracture was related to disjunction of the pubic symphysis consecutive to curettage of the pubic bones for septic osteitis developed after vulvectomy for cancer. The diagnosis was suspected on the results of bone scintigraphy and was confirmed by computerized tomography with frontal sections and contrast inversion, showing the characteristic H-shaped fracture.

[Bacterial endocarditis on prosthetic valves].

Bacterial endocarditis is a rare, but often lethal, complication of cardiac valve replacement. The endocarditis is called "early" when it occurs within 2 months of the operation, and "late" when it develops after that period. Contamination of the prosthesis with bacteria may occur intra-operatively or post-operatively. The clinical diagnosis is often difficult in early endocarditis when another focus of infection is present and in late endocarditis in the absence of fever and positive blood cultures. Isolation of the pathogen from blood cultures is essential to the diagnosis and treatment. Therapeutic surgery now has wider indications than formerly. The incidence of this dangerous complication can only be reduced by well-planned and well executed prophylactic measures.

[The advantages of histological samples in sarcoidosis. Retrospective multicenter analysis of 618 biopsies performed on 416 patients].

The diagnosis of sarcoidosis is based on the finding of an epithelioid granuloma at histological examination. A retrospective study of 618 biopsies obtained from 416 patients with sarcoid disease showed an average sensitivity of 69 p. 100. The sensitivity of guided biopsies, especially skin and lymph node biopsies, was almost 90 p. 100, whereas that of blind biopsies tended to increase with the degree of hazard involved, ranging from 49 p. 100 in proximal bronchial biopsy to 70 p. 100 in liver needle biopsy. When treatment is not urgently required, the Kveim test is safe, cheap and fairly sensitive (65 p. 100 positive results).

[Systemic lupus erythematous and seminoma of the ovary].

A new case of ovarian seminoma associated with systemic lupus erythematosus is reported. The neoplasia was discovered during a flare-up of lupus. Excision of the seminoma followed by radiotherapy resulted in a 7 1/2-year long remission of systemic lupus erythematosus. This case agrees in every detail with a previously reported case, which suggests a pathogenetic relation between the two diseases. Although this association is rare, clinicians must be aware of its possibility and cautious when confronted with an ovarian abnormality in a young woman with systemic lupus erythematosus.

[Arterial manifestations of Behçet's disease. 12 cases].

Out of 196 patients with Behçet's disease, 12 (10 men and 2 women, mean age 34 +/- 7 years) had non-coronary arterial lesions. Behçet's disease was complete in 4 patients. The arterial lesions had appeared 8.6 +/- 8 years on average (20 years at most) after the first sign of the disease. Three patients showed evidence of stenosis or occlusion involving one or several arteries. Eight patients had both stenotic and aneurysmal lesions. One patient had an arteriovenous fistula. Another developed a false aneurysm at the site of introduction of a femoral catheter. Yet another patient developed an anastomotic aneurysm one year after implantation of an abdominal aortic graft. In 2 cases histology showed fragmentation of the media associated with vasculitis of the vasa vasorum. Two patients with pulmonary aneurysm died of massive haemoptysis. In 2 patients combined corticosteroid and cyclophosphamide therapy failed to prevent the development of aneurysmal lesions. Phlebitis was associated with arterial involvement in 7 patients. Comparison between patients with or without arterial lesions showed no significant difference in time of onset of Behçet's disease, sex, main clinical features and presence of HLA B5. Aneurysmal lesions respond poorly to medical treatment, and surgery is mandatory. Since recurrence at the site of anastomosis is possible, prolonged monitoring is required.

[Systemic vasculitis associated with non-streptococcal infection. Report of 4 cases].

The responsibility of bacterial agents in the staring of systemic vasculitis is discussed on the basis of four cases: three men and one woman presenting with severe vasculitis which revealed or complicated a focus of infection without hematogenic dissemination. Two patients had gastrointestinal lesions and one had severe renal lesions. The vasculitis affected small caliber vessels, and in two out of four cases it involved arterioles of medium caliber with histological images resembling periarteritis nodosa. Antibiotic therapy alone was immediately effective against vasculitis. However, a purely cutaneous relapse occurred in three patients whose disease had regressed under an adjuvant treatment.

AL cardiac amyloidosis and arterial thromboembolic events.

OBJECTIVE: To study the prevalence and characteristics of arterial thromboembolic events (ATEE) in the course of AL amyloidosis. METHODS: We report the case of a non-anticoagulated patient with AL amyloidosis restrictive cardiomyopathy who developed acute lower limb ischaemia. We then prospectively determined the prevalence of ATEE in all patients with AL amyloidosis who were evaluated in our institution for autologous peripheral stem cell transplantation. RESULTS: Nine out of 15 non-anticoagulated patients (60%) developed ATEE: ischaemic stroke (3), transient cerebral ischaemic attack (2), multiple peripheral arterial emboli (1), bilateral iliac artery thrombosis (1), bilateral optic nerve ischaemia (1), and mesenteric ischaemia (1). Haemodynamic stasis seemed to play a leading role in the pathophysiology of ATEE, in that all patients were on sinus rhythm and only one had a thrombus on echocardiography. We identified possible contributing factors to ATEE occurrence: concomitant treatments with oestroprogestogen regimen, thalidomide, granulocyte-macrophage colony-stimulating factor (GM-CSF) and extracellular volume disturbances related to the cytapheresis procedure. CONCLUSION: We report on an unusual frequency of ATEE among patients with AL cardiac amyloidosis. Despite its theoretical risks, anticoagulation should be discussed for patients with amyloid cardiomyopathy.

Behcet's syndrome and renal involvement: a histological and immunofluorescent study of eleven renal biopsies.

The finding of focal glomerulonephritis in a patient with Behcet's syndrome led us to perform systematic renal biopsies in ten other patients with the disease. None of the patients had symptoms of renal disease. Proteinuria was found in five, two of whom had associated leukocyturia. By light microscopy mesangial and extramembranous glomerular deposits were observed in eight patients. Arterioles in ten patients showed subendothelial and medial hyaline deposits. A granular pattern of fluorescent staining identified the presence of the third component of complement in these deposits. Circulating immune deposits were sought and found in six out of seven patients. The finding of circulating immune complexes and deposition of complement in glomerular and arteriolar tissues supports an immune complex mediated nephropathy and is consistent with the hypothesis of an immunological pathogenesis in Behcet's syndrome.

Steroid-induced spinal epidural lipomatosis: CT survey.

A new case of spinal cord compression secondary to steroid-induced epidural lipomatosis is reported in a patient treated for dermatomyositis. Computed tomography was performed before the institution of steroid therapy, during spinal cord compression, and after effective surgical treatment. The development of epidural lipomatosis does not require a preexisting lipoma and may occur in a previously normal spine.
