Exposure to silica minerals is associated with silicosis and autoimmune disorders, especially systemic scleroderma. Evidence of this association has been increasingly reported in the last decade. The aim of this paper is to discuss, on the basis of a literature review, the case of a 28-year-old female dental technician who suffered from episodes of weakness, arthralgia, pain, swelling and stiffness of the fingers, dyspnoea with cough, a positive Waaler-Rose reaction, increased rheumatoid factor and normal ESR. She was a non-smoker. A rheumatoid syndrome with lung interstitial disorder, associated with silica exposure from dental ceramic products, was diagnosed. The patient had the HLA-A2-A31, HLA-B51-B18 and HLA-DR3-DR11 haplotypes, some of which are associated with autoimmune disease susceptibility. A 6-month follow-up, with adequate protection and without treatment, showed disappearance of the symptomatology and negative tests for Waaler-Rose reaction and rheumatoid factor. Exposure to silica should, therefore, be sought in the history of any patient with autoimmune or lupus-like syndrome and pulmonary changes. Symptoms associated with silica dust exposure from dental ceramic products should be recognised as being due potentially to an occupational disease, and dental technicians should be protected as workers at risk.

A 44-year-old male was initially seen by dermatologists, who noted an erythematous rash on sun-exposed areas, the back, shoulders, and upper arms. There was associated muscle weakness and significant weight loss. Investigation revealed mildly raised aspartate and alanine transaminases but normal creatine kinase. Inflammatory indices and antinuclear antibodies (ANAs) were normal. Biopsy of the rash was reported as consistent with either dermatomyositis (DM) or acute lupus erythematosus. A diagnosis of DM was made, and prednisolone was given with improvement of the rash but deteriorating myopathy. The patient was referred to the rheumatology department, and further history revealed multiple vertebral fractures after falling from standing height; these had occurred six months prior to starting steroids. Besides smoking he had no other risk factors for osteoporosis. Examination showed normal muscle strength, no muscle tenderness, and no joint abnormality. Repeat muscle enzymes were normal, and ANAs were now 1 : 100, but dsDNA antibodies and extractable nuclear antigens were normal. Investigations for osteoporosis revealed a hypergonadotrophic hypogonadism picture. Further examination indicated scanty pubic and auxiliary hair, small testicles, and mild gynecomastia. He is married, though has no children of his own. The hormonal profile raised the possibility of Klinefelter's syndrome, which was subsequently confirmed with karyotyping of 47 XXY. Hypogonadism has been established as a cause of osteoporosis in males, and in this case would explain the occurrence of fractures in the absence of other major risk factors. Systemic lupus erythematosus has been recognized in association with Klinefelter's syndrome; in view of the normal muscle enzymes, his rash is most likely due to acute discoid lupus with androgen deficiency causing muscle weakness.

To describe the clinical and immunologic characteristics of patients with adrenal involvement and antiphospholipid syndrome (APS), we conducted a computer-assisted (PubMed) search of the literature to identify all cases of primary adrenal insufficiency associated with antiphospholipid antibodies published in English, French, and Spanish from 1983 (when APS was first defined) through March 2002. We reviewed 86 patients (80 from the literature plus 6 from our cohort); 55% were male, and the mean age at presentation was 43 +/- 16 years. Sixty-one (71%) patients had primary APS, and 14 (16%) had systemic lupus erythematosus. In 31 (36%) patients, adrenal insufficiency was the first clinical manifestation of APS. Abdominal pain was present in 55% of patients, followed by hypotension (54%), fever (40%), nausea or vomiting (31%), weakness or fatigue (31%), and lethargy or altered mental status (19%). The main finding in imaging techniques was compatible with adrenal hemorrhage (59%) and in histopathologic study was a hemorrhagic infarction with vessel thrombosis (55%). Lupus anticoagulant was detected in 97% of patients and the anticardiolipin antibodies titer was positive in 93% of patients. Most patients (95%) were positive for the IgG isotype of anticardiolipin antibodies, whereas 40% were positive for the IgM isotype. Baseline cortisol levels were decreased in 98% of patients, ACTH hormone levels were increased in 96% of patients, and the cosyntropin stimulation test was positive in 100% of patients tested. Steroid replacement therapy was the most frequent treatment (84%), followed by anticoagulation (52%) and aspirin (6%). Thirty-two of 35 (91%) patients with prolonged anticoagulant therapy were in good health with a mean follow-up of 25 months, whereas 25 of the 69 (36%) patients with outcome data available had died. The results of the present review stress the clinical importance of systematic screening for lupus anticoagulant and anticardiolipin antibodies in all cases of adrenal hemorrhage or infarction. An initial screening for hypoadrenalism is mandatory in any antiphospholipid antibody-positive patient who complains of abdominal pain and undue weakness or asthenia.

The neurological manifestations of antiphospholipid syndrome (APS) are diverse. Transverse myelitis (TM) is an uncommon, but well-known neurological complication of systemic lupus erythematosus (SLE). On the other hand, the reported cases associated with primary APS are extremely rare. To our knowledge, this is the first report of TM in a patient with primary APS in Korea. A 32-year-old male patient was admitted with the sudden onset of numbness, a tingling sensation, and weakness in both lower extremities. He had a 19 months history of external iliac and femoral arterial thromboses prior to admission. The laboratory results indicated the presence of anticardiolipin antibodies of the IgG class and lupus anticoagulant. No other autoantibodies were detected and there were no apparent clinical manifestations of SLE or multiple sclerosis. A T2-weighted magnetic resonance (MR) image showed swelling and increased intensity of the cervical and thoracic spinal cord between C6 and T7 with slight enhancement by contrast medium. After steroid pulse therapy, the patient's symptoms were gradually relieved and the abnormal findings on MR imaging disappeared.

We report the clinical and bioptic findings for a 57-year-old woman with severe chloroquine-induced myopathy. Since 1989, she had been suffering from systemic lupus erythematosus (SLE) with renal involvement and undergone periods of treatment with azathioprine and cyclophosphamide. Additional therapy with chloroquine (CQ) was started because of arthralgia. At the same time, slightly increased creatine kinase (CK) levels were noted. Myositis was suspected, and the patient was treated with steroids. The CK increase persisted, however, and she developed progressive muscular weakness and muscular atrophy. Routine controls revealed markedly elevated CK levels of 1,700 U/l. The neurological and electrophysiological findings were not typical of myositis. Thus, muscle biopsy of the deltoid muscle was performed in order to exclude polymyositis or toxic myopathy. As it revealed chloroquine-induced myopathy, medication was stopped. Discriminating between primary SLE-induced affection of the musculoskeletal system and drug-induced side effects is important for appropriate treatment of SLE patients.

Myasthenia gravis is an autoimmune disorder that affects the neuromuscular junction and leads to weakness of the skeletal muscles. Associated autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis and pernicious anaemia are present in approximately 5% of the myasthenic patients. This report presents a 64-year-old man with autoimmune haemolytic anemia associated with myasthenia gravis and thymoma. The patient developed a severe Coomb's positive autoimmune haemolytic anaemia, which was resistant to treatment with large doses of prednisone. Haemolytic anaemia entered remission one month following thymectomy, and the patient has maintained a normal haemoglobin and a negative Coomb's test without the need for steroid or immunosuppressive therapy. In conclusion, thymectomy may induce a striking improvement of therapyresistant autoimmune haemolytic anemia in patients with MG and thymoma, but in terms of remission, a long follow-up is needed as autoimmune diseases can show spontaneous fluctuations.

A previously diagnosed systemic lupus erythematosus patient presented with arthralgia, skin rash and muscular weakness. When treated with high-dose corticosteroids and methotrexate she improved, except for a persistent lesion in the hand which evolved into a profound ulcer, along with tender subcutaneous nodules in the calf. A skin biopsy disclosed necrotizing vasculitis with giant cell granuloma revealing acid fast positive bacteria on ziels nilsen staining. A chest X-ray disclosed miliary tuberculosis (TB). The patient was diagnosed as miliary TB with prominent cutaneous involvement and treated with four anti-tuberculous drugs with slow resolution of her systemic, pulmonary and skin signs.

Twenty-nine patients with systemic lupus erythematosus were treated with a new synthetic unsaturated prednisolone derivative, triamcinolone, for as long as 11 months. This hormone is 1.3 times as powerful as prednisone and 4.4 times more potent than hydrocortisone as an anti-inflammatory agent. The average dose for beginning therapy in cases of mild systemic lupus erythematosus was 20.6 mg. a day. The average maintenance dose used to control mild exacerbations of the disease was 26.0 mg. a day. There was no evidence of sodium retention or potassium loss. Sixteen patients had upper gastrointestinal x-ray studies before and during therapy with triamcinolone. There was no evidence of peptic ulceration except in one patient who was receiving 96 mg. a day. Nine patients had gastric analysis with histamine before and during therapy. No significant changes were noted in results of these tests, even in the patient who had an ulcer. No abnormal increase in uropepsin was noted in cases in which this factor was tested. The pattern of clinical improvement closely paralleled that obtained by previous treatment with older steroids. There was a disappearance of all the clinical and laboratory abnormalities produced by the disease, with the exception of long standing renal involvement. A major difference between triamcinolone and other steroids was a tendency to progressive gradual loss of weight, partly owing to fluid loss. Cushingoid appearance produced by other steroid therapy did not disappear. The cutaneous side effects, particularly Cushingoid appearance, hirsutism and striae were more pronounced than with older steroids. The most serious side effect was muscle weakness which appeared in six patients, all women, in from four to thirty-two weeks after starting triamcinolone. The profound muscle weakness, most pronounced in the quadriceps group, gradually cleared after several weeks of therapy with another steroid. Fourteen patients had received prior steroid therapy with all the older anti-inflammatory hormones and seven of them were better controlled and felt better with triamcinolone.

Dermatomyositis represents a progressive autoimmune disease of the connective tissue with SLE-like dermatitis, with inflammatory myopathy and muscular weakness. It is an infrequent and serious disease affecting not only the skin and striated muscle. Cases without skin affection are classified as polymyositis. Beside autoimmune mechanisms, aetiology includes also genetic, environmental and paraneoplastic factors. Clinical skin symptoms as well as histopathological findings include Gottron's papulae, heliotropic periorbital erythrema, which, together with palpebral oedema, brings about the weepy look of patients. None of these signs is pathognomic and beside the cutaneous symptoms the diagnosis requires 3 out of 4 other diagnostic criteria for the muscle symptoms. Cutaneous symptoms can precede myositis with various time intervals; such situation is sometimes classified as Amyopathic dermatomyositis (ADM), dermatitis sine myositis or skin dermatomyositis. A case of an ADM patient and the analysis of problematic including the strategy of therapy are presented.
