BACKGROUND: The objective of the present study was to compare the silent form of giant cell arteritis (GCA) to the classic cephalic form of the disease. METHODS: We conducted a retrospective study based on a chart review of 50 consecutive, biopsy-proven GCA, recorded at a department of internal medicine. We sought to distinguish a silent form, defined by a prolonged inflammatory syndrome or fever of unknown origin with the absence of cephalic signs, polymyalgia rheumatica, or large artery involvement, from an overt "classic" cranial temporal arteritis. RESULTS: The prevalence of the silent form of GCA was 46% in our study. Abnormal temporal arteries were more frequent in the cephalic group. The silent GCA group had higher C-reactive protein levels (p<0.05), a higher platelet count (p<0.05), and lower serum albumin (p<0.05). There was no significant difference in temporal artery specimens in the two groups. Clinical relapses tended to be more frequent, and patients free of corticosteroids tended to be less frequent, in the cephalic group, though the difference was not statistically significant. CONCLUSIONS: The silent and cephalic forms of GCA could have distinct clinical and biological patterns and different outcomes. The limitation of our study was its retrospective design. Further studies are required to determine if this distinction is useful in treating GCA patients.

Antisynthetase syndrome belongs to the idiopathic myositis group which includes pulmonary interstitial disease, arthritis, Raynaud's phenomenon, and mechanic's hands , associated with the anti-Jo1 antibody. We report three cases of antisynthetase syndrome, and review the clinical characteristics, and prognosis factors dominated by interstitial pneumonia.

Objective: To evaluate the clinical and laboratory characteristics of patients with systemic vasculitis associated with temporal artery involvement., Methods: From a cohort of 120 patients fulfilling American College of Rheumatology criteria for temporal arteritis, we retrospectively identified 7 patients with systemic necrotizing vasculitis associated with histological temporal arteritis., Results: Among the 7 patients, 2 had classic polyarteritis nodosa, one had unclassified systemic vasculitis, one had Wegener's granulomatosis (WG), and 3 had microscopic polyangiitis. The mean age of the patients was 70.2 years, and cranial symptoms revealed the disease in all but one patient. Temporal arteritis was generally associated with extracephalic manifestations suggestive of systemic vasculitis. Antineutrophilic cytoplasmic antibodies were positive in 3 of the 4 patients with small vessel vasculitis. Pathologically, the main temporal artery was involved in all but one patient, with inflammatory infiltrate of vasa vasorum and adventitia associated in 5 with small tributary involvement. Fibrinoid necrosis was rare, observed in 2 specimens; 2 patients with unclassified systemic vasculitis and WG had a classic giant cell arteritis (GCA) histologic pattern. Only one patient had exclusive involvement of small vessels, surrounding the spared main temporal artery. Muscle biopsies showed histopathological evidence of vasculitis in 2 patients, skin biopsy in one, and vein biopsy in the other., Conclusion: Temporal artery involvement in systemic necrotizing vasculitis was generally associated with extracranial clinical features suggestive of systemic vasculitis. Temporal artery biopsy is a simple tool for diagnosis of vasculitis, but the histopathological findings do not always discriminate between necrotizing vasculitis and classic GCA.

Seven autoantibodies directed against synthetases have been identified to date, the best known being anti-Jo1. Synthetases play a vital role in protein synthesis by catalyzing the acetylation of transfer RNAs (tRNAs). The most common form of antisynthetase syndrome is characterized by anti-Jo1 production, interstitial lung disease (ILD), inflammatory muscle disease, and, in many cases, fever, polyarthritis, Raynaud's phenomenon, and thick cracked skin on the fingers (mechanic's hands). The interstitial lung disease is generally of the "usual interstitial pneumopathy" type and shares similarities with idiopathic pulmonary fibrosis or scleroderma-related pulmonary disease. It governs the prognosis of the disease, being associated with an excess mortality rate of about 40%. The pathogenic mechanisms underlying antisynthetase syndrome remain unknown but may involve cell-mediated immunity. The treatment is not standardized. The ILD responds to glucocorticoids in some patients but requires other immunosuppressant drugs in others.

Kikuchi-Fujimoto disease, or necrotizing histiocyte lymphadenitis, is a rare anatomo-clinical entity of unknown cause. The patients present painful cervical lymph nodes, fever, and a flu-like syndrome, but the spontaneous course is usually favorable in six months. We observed two cases within six months in our unit. Both patients improved rapidly after diagnostic adenectomy.

Background: Risk factors for the thrombo-embolic disease are not yet completely validated in medical setting. Indeed, there is a lack of scientific data concerning their prevalence and their thrombogenic weight., Methods: We carried out a prospective case-control study in an internal medicine unit where general acute pathologies are recruited. We have included two patients without thrombosis for each patient admitted for a thrombo-embolic event. In all patients, at admission, clinical and biological risk factors for thromboembolism were systematically analysed in a physiopathological and chronological way., Results: 450 patients were included during the 27 months period of the study. Among these patients, 150 were hospitalised for a deep venous thrombosis of the leg or/and a pulmonary embolism. Height risk factors have demonstrated their high thrombogenic potential: paralysis of the legs (OR = 13; 95% CI: 1.4 to 5.1), post-thrombotic syndromes (OR = 13; CI: 1.7 to 4.3), extrinsic compressions (OR = 8; CI: 1.3 to 5.4), pregnancy (OR = 6; CI: 1.2 to 6), malignancy occurred one year before (OR = 4; CI: 1.1 to 6.7), personal history of deep vein thrombosis (OR = 3; CI: 1.6 to 4.5), varicosity (OR = 2.5; CI: 1.2 to 6.1) and venous insufficiency (OR = 1.7; CI: 1 to 7.4). Four parameters, generally considered as risk factors, didn't prove here their pathogenic power: the age over 60, obesity (BMI > 27), bedrest and the presence of an on-going malignancy., Conclusions: Only risk factors with high thrombogenic power (as paralysis or extrinsic compression for example) could be identified by this kind of study performed in polypathological patients. In this particular population, usually recognised risk factors as age, obesity and bedrest are not determinant parameters for the thomboembolic risk evaluation.

Purpose: Pathogeny of hypoglycemia associated with non-islet-cell tumors is unclear. We discuss the mechanisms of this syndrome., Current Knowledge and Key Points: We report three cases of spontaneous hypoglycemia revealing pleural fibroma. Endocrine tests before surgery showed low serum growth hormone and insulin-like growth factor I (IGF-I), reduced serum IGF-II levels in two patient. Insulin-like growth factor binding protein-3 (IGFBP-3) was low and electrophoretic profile of IGF-II was the 'big IGF-II' type. We discuss the mechanisms of hypoglycemia associated with non-islet-cell tumor. Impaired formation of the ternary complexes and its consequences seem the main pathogenic factor., Future Prospects and Projects: Analysis of IGF and IGFBP and in situ measurements of IGF mRNA could help in understanding this syndrome and allow therapeutic considerations in the management of hypoglycemia by corticosteroids and growth hormone.

Objective: To determine the clinical aspects of systemic vasculitis associated with chronic myelomonocytic leukemia (CMML)., Methods: In this retrospective study, 8 patients suffering from systemic vasculitis associated with CMML are described. The French and English literature on systemic vasculitis associated with myelodysplasia was reviewed., Results: All 8 patients had a systemic medium-sized vessel vasculitis which fulfilled the American College of Rheumatology criteria for polyarteritis nodosa in the setting of active CMML. Antineutrophil cytoplasmic antibodies (ANCA) were negative in 7 patients. One patient had cytoplasmic ANCA by indirect immunofluorescence without antiproteinase 3 or antimyeloperoxydase antibodies on the enzyme-linked immunosorbent assay. At presentation, 6 patients had fever of unknown origin, 5 had polymyalgia rheumatica, 3 had sensory hearing loss, and 4 had eosinophilia. None had viral infection or drug-associated vasculitis. Diagnostic procedures included renal or hepatic angiography in 6 patients which showed microaneurysms in 4, skin and temporal artery biopsy in 2 which showed vasculitis, and 1 postmortem examination which showed gastroduodenal arteritis. All patients were treated with corticosteroids, and 7 received immunosuppressive drugs. Death was attributable to vasculitis in 2 cases, infection in 3, and other vasculitis-related causes in 2. In a review of the French-English literature, we found 11 similar cases of ANCA-negative systemic vasculitis, generally associated with refractory anemia, with or without blast excess., Conclusions: Systemic ANCA-negative polyarteritis nodosa-type vasculitis seems closely associated to CMML. Clinical presentation is nonspecific, and systemic vasculitis should be suspected when a patient with myelodysplasia develops atypical manifestations. Renal, gastrointestinal, or hepatic angiography are useful diagnostic procedures when more invasive biopsies should be avoided because of low platelet count. The prognosis of CMML-associated systemic vasculitis is poor., (Copyright 2001 by W.B. Saunders Company)

Purpose: The thromboembolic risk is difficult to evaluate in medical inpatients because of the multiplicity of risk factors. The lack of scientific data leads to a certain empiricism in selection of patients who need a preventive treatment., Methods: All patients hospitalised in an internal medicine department were included during 34 months. The pathogenic mechanism of risk factors (venous stasis or hypercoagulability) was analysed as well as their progress (transient or permanent risk factors) and their pathogenic weight (major risk factor or not). Three levels of embolic risk (high, intermediate, low) were identified. A preventive treatment was initiated only for patients at high or intermediate risk. A clinical screening for thromboembolic events was performed daily. Therefore, we have excluded patients who needed a hypocoagulant treatment., Results: Nine hundred and forty-seven patients were included. Age (over 60) was the most frequent permanent risk factor (70%). Bed rest was the most frequent transient risk factor responsible for venous stasis. Fifty percent of patients had a transient and permanent risk factor and needed a preventive treatment according to our selection criteria. The incidence of thromboembolic events was 0.4% in the high-risk treated group and 0.2% in the low-risk non-treated group., Conclusions: Venous stasis factors are the more frequent risk factor in internal medicine, perhaps because of the increasing number of geriatric patients. The incidence of thromboembolic disease is low in high-risk inpatients when a preventive treatment is performed.

Two cases of systemic antineutrophil cytoplasmic antibody (ANCA) vasculitis in the setting of chronic lymphocytic leukaemia and angioimmunoblastic lymphadenopathy type T cell lymphoma are reported. The two patients had fever of unknown origin associated with cutaneous vasculitis and "pulmonary-renal syndrome" with alveolar haemorrhage. Despite anti-infectious treatments, steroids, and chemotherapy, the vasculitis had a fatal paraneoplastic course in several weeks. When infection is excluded in patients with malignancy, atypical features should be promptly investigated for systemic vasculitis, and an ANCA test performed.

Background: In terms of preventive management of venous thromboembolism in medical inpatients, very large differences may be observed. Rationalization of behaviour requires the evaluation of simple and logical parameters, which takes into account both patient safety and economic considerations., Aim: The aim of this study was to evaluate a preventive scheme including the rationalization of the indications and the use of low molecular weight heparin., Experimental Design: Epidemiologic investigation., Setting and Patients: Patients hospitalized in five medical departments in the Hospital Center of Nantes, France., Intervention: The risk of venous thromboembolism was rated as high, intermediate and low. Patients with high or intermediate risk were eligible for prevention therapy (table I)., Measures: The main criterion was the occurrence during hospital stay of deep or superficial venous thrombosis of the lower limbs, pulmonary embolism, or unexplained sudden death. The screening was based on clinical features double-checked by venous doppler ultrasonography of the lower limbs and/or ventilation-perfusion lung scanning., Results: 24,497 patients were eligible (table II), 15% were considered at risk and treated with Nadroparin, 6% had the same risk profile but were not treated and 14. 7% had low risk and no prevention. No bleeding event was reported. The incidence of venous thromboembolism was 0.75%, 1.7% and 0.14% respectively (p <0.01) (table III). This efficacy does not appear to depend on body weight or the existence of multiple risk factors observed (table IV and V)., Conclusions: This analysis of risk factors separates two populations with rates of incidence dramatically and significantly different. The prevention of venous thromboembolism by fixed dose of low molecular weight heparin remains justified since it reduces the risk of venous thromboembolism by a factor of 2.5.

Objective: To evaluate the prevalence of antineutrophil cytoplasmic antibodies (ANCA) and rheumatic manifestations associated with chronic haematological malignancies., Methods: Two groups of patients were prospectively studied (group I: 60 patients with myelodysplastic syndromes and group II: 140 patients with lymphoid malignancies) for clinical 'immune' manifestations and ANCA., Results: In the myelodysplastic group, six patients had ANCA-negative systemic medium-size vasculitis, one had systemic vasculitis with cytoplasmic ANCA, one relapsing polychondritis, one giant cell arteritis, one polymyalgia rheumatica, one polyarthritis and two fasciitis. In group II, two patients had ANCA-negative systemic vasculitis, two had leucocytoclastic vasculitis associated with tuberculosis, two had polyarthritis, one polymyalgia rheumatica and one giant cell arteritis. Six sera were ANCA-positive with perinuclear pattern in four cases, atypical pattern in one and cytoplasmic pattern in one. Two sera had anti-myeloperoxidase (MPO) specificity, and others had no known specificity; none had anti-proteinase 3 (PR3) specificity. Global prevalence of ANCA in our cohort was 3%, similar to the French general population., Conclusion: Polyarteritis nodosa-type systemic vasculitis and polymyalgia rheumatica were the most frequent findings (18%) in myelodysplastic syndromes and particularly in chronic myelomonocytic leukaemia. ANCA were not helpful for the diagnosis of vasculitis. Vasculitis associated with infection, in particular tuberculosis, must be ruled out.

We describe a case of Henoch-Schönlein purpura in the onset of Toxocara canis infection. The diagnosis was made in a 17-year-old boy based on the association of palpable purpura, oligoarthritis, acute abdominal pain, microhematuria, and cutaneous vasculitis. Toxocariasis, suggested by hypereosinophilia and domestic contact with a puppy, was confirmed by anti-Toxocara IgG and IgE and Western blot. Complete spontaneous resolution occurred within a few days. Transient presence of antinuclear antibodies and the absence of larvae in the skin biopsy favor an immunologic parasite induced disorder. A hypersensitivity vasculitis to Toxocara canis is suggested.

Introduction: The authors report a case of neurologic manifestations revealing Richter's syndrome in chronic lymphocytic leukemia., Exegesis: Cranial nerve palsies were the initial manifestation of the disease. Computed tomography and magnetic resonance imaging were normal. Cerebrospinal fluid analysis with alkaline phosphatase-antialkaline phosphatase revealed the existence of a large-cell lymphoma., Conclusions: Clinical aspects of this unusual localization of Richter's syndrome are reviewed.

Introduction: Willebrand's syndrome is rarely acquired. We report four cases associated with lymphoproliferative syndromes., Case Reports: We observed four patients with lymphoid hemopathies who developed acquired Willebrand's syndrome. Two patients had Waldenström's disease (kappa), one had a monoclonal gammapathy of undetermined signification (kappa immunoglobulin M) and the fourth had chronic lymphoid leukemia with mast cell infiltration of the skin. Anti-vWFRCo antibodies were evidenced in only 1 case. Chemotherapy, used in 3 cases, improved hemostasis in one patient. Intravenous immunoglobulins (1 patient) and desmopressin (2 patients) were ineffective. The pathogenic mechanisms and possible therapeutic approaches to acquired Willebrand's syndrome are discussed., Discussion: Acquired Willebrand's syndrome rarely occurs in association with lymphoproliferative disorders appears to be uncommon but the frequency is probably underestimated because appropriate tests are not always performed. The diagnostic search is important however since the hemostasis disorders due to acquired Willebrand's syndrome could be corrected if appropriate etiological treatment is given.

Determination of the protein profile of orientation (PPO) is now considered by some authors as a means of improving the diagnosis in internal medicine. The feasibility of systematizing this practice was investigated in 76 outpatients (79 included, three excluded secondarily) seen for pathology of undetermined diagnosis. The 79 patients (mean age: 52 years) underwent the classical biological explorations plus PPO. The physicians were divided into two groups (seniors and assistants). Two complete clinical files were established for each patient, with one difference concerning inflammatory and immunologic data: one file included the minimum number of tests considered necessary by the physician and the other the complete PPO (nine proteins). Each file (with or without PPO) was randomly distributed to one of two physicians in the same group. Each physician filled in a diagnostic evaluation sheet indicating whether there was organic pathology or not, the main diagnosis (inflammatory, neoplastic, infectious or other), the secondary diagnosis and the hypothesis of probability. The relevance of the clinical opinion was analyzed by an internal medicine specialist from outside the department with 40 years of clinical experience. The duration of symptoms before the medical visit was from 3 weeks to 5 years (mean 6 months). A diagnosis of organic pathology was reached for three out of four patients. Sixty-seven patients were seen again after a minimum of 6 months, and nine were lost to follow-up. Diagnostic efficiency was no greater for cases with PPO, which appears to be a biological examination of second intention. We suggest that the term "protein profile of orientation" be replaced by "broad protein profile."

Severe adverse effects of low-dose methotrexate (less than 20 mg per week) are believed to be rare. We report eight cases of severe tricytopenia or pancytopenia seen in two medical departments of the same hospital in patients receiving low-dose methotrexate. Three patients had been under methotrexate for less than one month. Of the six patients with joint disease, five had rheumatoid arthritis and one psoriatic arthritis. A review of the literature found 92 previously reported cases of severe tricytopenia or pancytopenia induced by low-dose methotrexate. Of the total of 100 cases, 24 were fatal and 25 occurred within one month of treatment initiation. Potential risk factors were identifiable retrospectively in at least 50% of cases but were not all predictable or present at treatment initiation. In 30% of cases, no explanation for the hematologic complication was found, and in an additional 20% missing data precluded definite conclusions. The role of the risk factors incriminated in the literature is discussed. Although infrequent, cytopenia is a severe complication of methotrexate therapy that warrants a number of precautions, including periodic creatinine clearance and serum albumin determinations. Furthermore, the weekly dosing schedule should be printed on methotrexate boxes.

Treatment of antiphospholipid syndrome (APS) is controversial. We report a case of renal microangiopathy in a 40-year-old woman with APS. The nephropathy was isolated without signs of disseminated thrombotic microangiopathy or progressive systemic sclerosis. Similarities with sclerodermatous kidney and an increase in plasma renin activity led us to initiate treatment with aspirin and captopril, with excellent control of the renal syndrome. We believe this therapeutic regimen may be an effective means of treating the renal microangiopathy of APS.

We report the case of a woman splenectomized to treat her hairy cell leukemia (at the moment in remission) 11 years before the detection of neutropenia. The neutropenia began just after the treatment of pulmonary embolism by acenocoumarol. The neutropenia disappeared quickly after substitution of acenocoumarol by fluindione. We discuss the attribution of the neutropenia to acenocoumarol and the part played by hairy cell leukemia.

From a prospective study concerning 576 patients with Raynaud's phenomenon, the authors studied the results of Allen's clinical test and their etiologic significance. These results were compared to those obtained by the instrumental technique using the Doppler probe to locate and compress radial and ulnar arteries and digital plethysmography to measure the effects of this compression. This instrumental technique makes it possible to investigate hand vascularization when Allen's clinical test is non interpretable or impossible which corresponds to 30% patients. A pathological Allen's test, whether it be clinical or instrumental, rather favors a Raynaud's syndrome (p < 10(-4)). The absence of ulnar vascularization was the abnormality most often noted and was rather found in severe Raynaud's phenomena, the sclerodermatous particularly (p < 10(-4)).

The authors report 7 cases of bone marrow necrosis during hematological malignant diseases:3 leukemia, 4 lymphoid malignancies. The main clinical features were bone pain and fever. The bone marrow aspiration and/or biopsy allow diagnosis. The prognosis was in all cases very poor.

The coexistence of giant cell arteritis (GCA) and autoimmune thyroid diseases has been suggested. In our prospective study of 39 patients with GCA, we measured autoantibodies and thyroid function and compared the results to those of a control group. No statistical difference was found. Our conclusions differ from those of other authors.

The authors report a case of amyloidosis AL associated with light lambda chain myeloma, mimicking giant cell temporal arteritis. The normality of inflammatory proteins, the primary resistance to corcicosteroids and the results of temporal artery biopsy (amyloid deposits without giant cell granuloma) excluded a diagnosis of giant cell arteritis associated with amyloidosis. The most probable mechanism was infiltration of branches of the external carotid artery. In patients with temporal arteritis, amyloidosis must be suspected and sought, particularly in case of monoclonal dysglobulinaemia or manifestations that are not typical of giant cell temporal arteritis. The prognosis of vascular amyloidosis seems to be more favourable than that of the classical visceral types. The primary amyloidosis of these patients must be treated with melphalan combined with prednisone and colchicine.

Endocrine function was prospectively evaluated in 98 patients (73 men and 25 women) infected by HIV in various stages of illness: Centers for Disease Control groups II (19), III (20), IVA and IVC2 (27), IVC1 and IVD (32). Testing included baseline and post-stimulation evaluation of gonadal, thyroidal, and adrenal axes. Although adrenal function was within normal values in most cases, with no differences between patient groups, nine out of 98 patients had either a low baseline or post-stimulation serum cortisol, cytomegalovirus adrenalitis being suspected in two cases. Mineralocorticoid response was normal in all individuals. The main abnormalities were sick euthyroid syndrome with low tri-idothyronine and/or thyroxine in 16% of patients and hypotestosteronemia in 29% of men with AIDS. These abnormalities, related to a functional deficiency of the hypothalamic-pituitary axis, were highly correlated with the degree of illness, i.e. weight loss and low CD4+ cell count. It was concluded that endocrine dysfunction in HIV-infected patients is rarely of clinical significance, that it is related more to cachexia and advanced disease than to HIV or opportunistic infections, and that it could serve as a prognostic marker.

We evaluated the efficacy and toxicity of piperacillin-ofloxacin as an empiric treatment of fever in patients with neutropenia. 24 febrile episodes occurring in 21 patients (mean neutropenia: 204/mm3) were treated. The neutropenia was due to an hematologic malignancy in 6 cases and to chemotherapy in 15 cases. Fever was related to septicemia in 4 cases, urinary tract infection in 1 case, other infectious sites without microbiological documentation in 11 cases, and was of unknown origin in 8 cases. Empirical therapy was started within 24 hours of the occurrence of fever greater than 38.5 degrees C with the combination of intravenous piperacillin (12 g/day in 3 divided doses) and oral ofloxacin (400 mg/day in 2 doses). The overall response rate was 86% (19/22) of evaluable cases, with an immediate success rate (apyrexia within 48 hours) of 46%. Of the 3 failures, one was bacteriologically documented and was due to a multiply resistant strain of Staphylococcus haemolyticus (to which both piperacillin and ofloxacin were resistant). The therapy was clinically well tolerated in all except 3 patients, in whom intolerance to intravenous piperacillin was observed, leading to discontinuation of the drug in 2 cases. More extensive and comparative trials should better determine the place of this piperacillin-ofloxacin combination as first-line treatment of febrile episodes in patients with neutropenia.

Associated ultrasonic Doppler study (D) and plethysmography (P) were evaluated as compared to phlebography in diagnosis of venous thrombosis of the lower limbs (TVP). Probes (5 and 7.5 MHz respectively) were used in D for examination of proximal and calf veins. Plethysmography using a mercury ring gauge (Perivein, ETNA) was considered pathologic if filling volume was less than 1.5 vol% and/or emptying volume less than 40 ml/min/100 ml. One hundred and four patients hospitalized in an internal medicine department for suspected deep venous thrombosis were studied, including 97 for whom phlebography interpretation was unmistakable: 11 calf vein, 28 collector trunk and 42 total limb involvement TVP. In these localizations, D sensitivity was respectively 55, 72 and 100% (mean 85.5%) and that of P 63.5, 68 and 88% (mean 77.7%); association of D or P improved sensitivity: 82, 82 and 100% (mean 91.5%). Specificity was 86.6% for D, a poor 62.5% for P and 93.5% for associated D and P. The results are comparable to those in the literature but disappointing for diagnosis of isolated calf vein TVP. False-negatives in both D and P were due to strong collateral circulation or limited thrombus extension.

Deoxyuridine (dU) suppression test and granulocyte macrophage colony forming unit (CFU-GM) assay were performed, along with morphological analysis, vitamin B12 and folate assays, in 22 cases of macrocytic anaemia corresponding to various types of idiopathic dysmyelopoietic syndromes. The dU suppressive effect was found to be normal in 19 cases, and slightly subnormal in 3 cases. The parallel study of the in vitro bone marrow growth showed, except in cases of primary acquired sideroblastic anaemia, a reduced number of colonies associated with a relative increase of the cluster formation. Consequently, these two parallel functional studies can support a formal diagnosis of potentially preleukaemic myelodysplasia, whatever may be the morphological pattern and even in cases of marked macrocytic anaemias and secondary epiphenomenal folate or vitamin B12 deficiency.

A 63-year-old man, with a Waldenström's disease discovered by cryoglobulinemia (ischemic lesions of fingers) was quickly aggravating (hyperviscosity syndrome) under treatment by chlorambucil in a dosage of 8 mg daily. We obtained a dramatic remission with combination of cyclophosphamide, vincristine, adriamycin and prednisone surrounding a total body irradiation. A new trial of polychimiotherapy (with lower dosage) for severe Waldenström's disease is actually on study.

To evaluate two methods of obtaining lower respiratory tract secretions, fiberoptic bronchoscopy (FB) and transtracheal aspiration (TA) were performed in ten patients. FB used an open-end brush-in catheter. TA was performed as described by Pecora. TA gave significantly better sensitivity and specificity (3/5 and O false positive results respectively) than FB (2/5 and 5 false positive results). TA gives specimens which reflect the bacterial flora of the lung more reliably than those taken during FB.
