We describe the histopathologic changes of skin, muscle, vessels, and fascia in 11 patients with eosinophilia myalgia syndrome, a newly described entity that has been linked to the ingestion of L-tryptophan. This syndrome is defined clinically by severe incapacitating myalgias and a peripheral eosinophilia. Arthralgias, edema of the extremities, morbilliform rashes, skin induration, weakness, fatigue, and respiratory weakness may be present as well. The earliest apparent histologic changes were observed at the septa between subcutaneous fat lobules and in the deep dermis or fascia. The septa and fascia were infiltrated with a sparse mixture of lymphocytes and histiocytes. In the deep fascia, in addition to inflammatory cells, there were distinctive, reactive mesenchymal cells that showed features of both histiocytes and fibrocytes. Minimal tissue eosinophilia was seen despite the extent of blood eosinophilia. Dermal thickening and homogenization of collagen bundles occurred with replacement of fat and adnexa (changes indistinguishable from scleroderma or morphea). Vessel walls in the dermis and fascia showed thickening and endothelial swelling, but no overt vasculitis was noted. Skeletal muscle biopsies showed a perimysial, epimysial, and/or fascial inflammatory infiltrate of lymphocytes and distinctive reactive mesenchymal cells with some eosinophils. Minimal myofiber atrophy, regeneration, or necrosis was seen despite the clinical history of severe myalgias in almost all patients. This syndrome should help gain insight into the mechanisms of fibrosis in environmental-induced, scleroderma-like syndromes and in idiopathic, scleroderma-like disorders as well.

Acrodermatitis chronica atrophicans (ACA) was diagnosed in 15 patients from the southern and eastern part of Friesland (the Netherlands). Twelve patients had one leg affected; three had more than one extremity involved. Frequent complaints were fatigue, paraesthesia, swelling and blue discoloration. The symptoms persisted for many years in most cases. The inflammatory stage was observed most frequently (13/15): violet-blue erythema, oedema, firm swelling and nodules. Atrophy (4/15) was observed once in the form of a scleroderma-like lesion. Neuropathy was found in five patients. Histological investigation showed infiltration with lymphocytes and plasma cells (13/15) and atrophy (2/15). Spirochaetes were demonstrated in biopsies of 13 patients. Specific antibodies against Borrelia burgdorferi were found in all patients. ACA appears to be not infrequent and must be distinguished from other inflammatory and vascular diseases, such as chronic venous insufficiency.

More than 100 patient-years' experience has been acquired in the treatment of 133 patients with ambulatory home total parenteral nutrition (TPN) between May 1974 and December 1983. Indications for chronic or permanent home TPN include short bowel syndrome, malabsorption, scleroderma, and vasoactive intestinal polypeptide syndrome. Indications for acute or temporary home TPN include Crohn's disease, malignancies, gastrointestinal fistulas, ulcerative colitis, anorexia nervosa, and numerous other disorders. Eighty-two patients in the acute group were treated primarily with percutaneously placed standard subclavian catheters and 51 patients in the chronic group have been treated thus far with implanted silicone rubber, Dacron-cuffed catheters for a cumulative total of 38,939 patient days. Of the 125 implanted catheters, 115 were placed in the superior vena cava and ten in the inferior vena cava for an average duration of 250 catheter-days, the longest single catheter remaining in situ for more than 8 1/2 years. Catheter-related sepsis occurred 33 times with the implanted catheters, or once every 2.6 catheter-years. One hundred and fourteen temporary catheters were placed percutaneously in the superior vena cava via a subclavian vein for an average duration of 68 days, the longest single catheter remaining in situ for 213 days. Catheter-related sepsis occurred seven times, equivalent to one episode per 3 catheter-years. Total catheter-related complications were quite infrequent and were directly related to duration of catheterization. They included venous thrombosis (12), clotted catheter (11), catheter failure or rupture (8), catheter compression (5) and inadvertent catheter removal (4). Twenty-six catheters were repaired or spliced in situ when the external segment was accidentally damaged or deteriorated secondary to long-term material fatigue. One remarkable patient has been maintained exclusively by TPN originally as an inpatient and subsequently as an outpatient for the entire 13 years of his life.

Over 100 cases of disorders closely resembling classic autoimmune diseases have been reported among patients who were injected or implanted with a diverse group of chemicals including paraffins, vegetable oils or silicone. Most cases have occurred in silicone breast implant recipients, especially those who received their prostheses 2-10 years prior to onset of symptoms. A high proportion of patients exhibit classic signs and symptoms of Sjogren's syndrome or scleroderma. Affected patients typically experience some combination of fatigue, myalgia, joint pain, sicca syndrome (dry eyes and mouth), synovitis, rash, alopecia, muscular weakness or lymphadenopathy, and autoantibody formation. Less commonly, patients may have the CREST syndrome (calcinosis, Raynaud's phenomena, esophageal hypomotility, sclerodactyly and telangiectasias), hypertension, pulmonary fibrosis, or central nervous system pathology.

A 68-year-old white woman was referred to us by her rheumatologist for possible participation in a clinical study of photopheresis for scleroderma. In February 1993, she noticed edema of her distal phalanges, Raynaud's phenomenon in both hands, flu-like symptoms, fatigue, intermittent diarrhea, abdominal pain, tearing in both eyes, dyspnea on exertion, dysphagia, and odynophagia. Bilateral silicone-gel breast implants had been placed 12 years before; 2 months before her present evaluation, they were removed and found to be ruptured. Physical examination revealed edema, limited to the fingers and hands bilaterally, and slight induration of the skin on the dorsum of both hands and distal forearms. The remainder of the physical examination was normal. According to our study protocol, a skin biopsy specimen from the dorsum of the right hand was taken, but all other laboratory investigations were refused. Histopathologic examination revealed multiple clear spaces of varying sizes in the dermis and multinucleated macrophages containing small refractile particles, characteristic of silicone granuloma (Figs. 1 and 2); however, the specimen showed no evidence of scleroderma. X-ray energy dispersive analysis by scanning electron-microscopy confirmed the presence of elemental silicon in the small refractile particles. The patient did not receive any treatment after her diagnosis and shortly thereafter, she was lost to follow-up.

Weakness and fatigue are common symptoms in patients with scleroderma and may be due at least in part to underlying abnormalities of muscle. Various modalities, including electromyography, histologic examination of biopsy specimens, MR imaging, and MR spectroscopy are useful in defining muscle abnormalities in these patients. Recent studies using P-31 MR spectroscopy and near infrared spectroscopy demonstrate the presence of underlying metabolic abnormalities that may contribute to the clinical findings of weakness and fatigue.

The silicone breast implant controversy rages on. Recent work has demonstrated that normal or baseline breast tissue silicon levels in women who had had no prior exposure to any type of breast implant may be as high as 446 microg/gm of tissue. These data ranged from 4 to 446 microg/gm of tissue, with a median of 27.0 microg/gm of tissue. In addition, numerous other epidemiologic and rheumatologic studies have demonstrated no association between silicone breast implants and any connective-tissue diseases. Despite these reports, the use of silicone implants remains restricted. The present study measured breast and capsular tissue silicon levels from 23 breasts in 14 patients with saline implants, and from 42 breasts in 29 patients with silicone implants. No patient in the saline implant group presented with signs or symptoms of connective-tissue disease. Patients with silicone implants, however, were divided into three groups based on the presence or absence of signs or symptoms of connective-tissue disease: group I, no symptoms or signs; group II, + symptoms, no signs; and group III, + symptoms, + signs. Six patients in group III were diagnosed with a specific connective-tissue disease, including systemic lupus erythematosus, rheumatoid arthritis, or scleroderma. The most common indications for implant removal or exchange were capsular contracture and implant rupture, although 41 percent of patients with silicone implants expressed media-related concern over the implant issue. The most common symptoms described by patients in groups II and III were joint pain and stiffness, arm pain and numbness, and fatigue. In all groups, capsular tissue silicon levels were significantly greater than breast tissue levels. This finding may indicate that the capsule serves as a barrier to the distribution of silicone from the implant into adjacent breast tissue. Although breast tissue silicon levels in patients with silicone implants were not significantly greater than those in patients with saline implants (p = 0.48), capsular tissue levels in patients with silicone implants were, indeed, significantly greater than those in patients with saline implants (p < 0.001). However, no statistically significant differences in tissue silicon levels were observed with relation to the presence or absence of connective-tissue disease signs or symptoms in patients with silicone implants (groups I to III). Therefore, these data strengthen the conclusion that there is no association between tissue silicon levels and connective-tissue disease.

A 47-year-old woman was admitted to our hospital for evaluation of general fatigue and dyspnea. She had been diagnosed with progressive systemic sclerosis (PSS) when she was 39 years of age, on the basis of Raynaud's phenomenon, proximal sclerosis, and pigmentation of the skin. On admission, her blood pressure was 206/128 mmHg. Funduscopy revealed grade III (Keith & Wagener) hypertensive retinopathy. Laboratory data showed positivity for anti-nuclear antibody and anticardiolipin beta 2 glycoprotein I antibody, and the plasma level of renin activity (PRA) was abnormally high. Chest X-ray and UCG revealed massive pericardial effusion. On the second hospital day, she was operated on for pericardiodiaphragmatic fenestration. The volume of pericardial effusion amounted to more than 2000 ml. Post operative malignant hypertension persisted. Laboratory data showed thrombocytopenia, hemolytic anemia, and acute renal failure. We diagnosed scleroderma renal crisis (SRC) associated with antiphospholipid syndrome. Following the initiation of angiotensin converting enzyme inhibitor (ACE-I) combined with calcium antagonist and alpha-one blocker, her blood pressure and PRA decreased. She also had been treated with aspirin 81 mg daily. These therapies were effective in recovering the platelet count and stopped the progression of anemia and renal failure. Although either the finding of large pericardial effusion or SRC is associated with poor prognosis in PSS, this case has had a good clinical course. In this case, the findings suggested that anti-phospholipid antibody may have contributed to the pericarditis and SRC.

We successfully treated a 33-year-old woman with etoposide who developed systemic sclerosis (SSc)-associated refractory hemophagocytic syndrome (HPS). She had been diagnosed as SSc because she had had Raynaud's phenomenon, proximal scleroderma, telangiectasia, microstomia, thickening and shortening of lingual frenulum and positive antinuclear antibody since 1994. In September 1999, she showed high fever, anemia, thrombocytopenia, elevation of serum lactate dehydrogenase (LDH) and ferritin levels and hemophagocytosis in her bone marrow, which led to the diagnosis of HPS. Her symptoms were improved by 40 mg of daily oral prednisolone (PSL). While tapering PSL, she complained right coxalgia and magnetic resonance image (MRI) depicted avascular necrosis (AVN) of right femoral head. In May 2000, she again suffered from HPS when she was taking 19 mg of PSL daily. To avoid the development of another AVN of her bone, she was treated with monthly cyclophosphamide (CPA) pulse therapy (300-400 mg/day). Although her HPS transiently ameliorated with CPA, it flared up again with high fever, general fatigue, severe pancytopenia and extremely high serum LDH and ferritin levels after the 4th CPA pulse therapy. She was admitted again to our hospital and PSL was increased to 40 mg daily which did not improve HPS. We, therefore, treated her with intravenous etoposide (100 mg/day, three consecutive days) along with granulocyte-colony stimulating factor (G-CSF). She developed transient bone marrow suppression, but her laboratory data gradually normalized within two weeks and she became afebrile after 18 days of etoposide administration. This is the first case in the literature which suggests the efficacy of etoposide against refractory autoimmune-associated hemophagocytic syndrome.

The role of eosinophilia in connective tissue diseases and the relationship between symptoms of rheumatic disease and eosinophilia have not been clearly established. The purpose of the present study was to explore the prevalence of eosinophilia in rheumatologic disease and determine its relationship to the symptoms. One thousand patients who applied to our rheumatology outpatient clinic between 2001 and 2002 were prospectively studied. The upper limit of normal blood eosinophil numbers was determined as 500 cells/microl of blood. A detailed history was obtained from all patients and careful physical examination was done. A negative correlation was observed between eosinophilia and dryness of the mouth, vitiligo, and fatigue (P < 0.05). Nonsteroidal anti-inflammatory drug usage correlated positively with eosinophilia, which was also statistically meaningful (P < 0.05). Twenty-six of our patients with fibromyalgia (n = 293), three of our subjects with rheumatoid arthritis who were using methotrexate (n = 182), 15 of whom who were not on methotrexate therapy, and one of the 26 with vasculitis had eosinophilia, which was not statistically significant (P > 0.05). None of the patients with scleroderma (n = 12) had eosinophilia. Eleven of the patients with gout had eosinophilia, and only one of them was using allopurinol. We conclude that eosinophilia can be seen in various rheumatologic conditions but, as corticosteroids are one of the most common medications used in collagen tissue diseases, the eosinophil numbers found may be lower than expected and eosinophilia may be more frequent than reported.
