Goats, sheep and calves were inoculated intravenously with strain Y3343 of the large colony type of Mycoplasma mycoides subsp. mycoides isolated from a goat with polyarthritis. The goats and sheep died of septicemia (one was killed in extremis) within eight days. The goats had leukopenia and granulocytopenia. Coagulopathy was indicated in some goats; the fibrinogen titer, prothrombin and partial thromboplastin times increased with the progress of disease and the number of platelets decreased dramatically in one goat. Goats and sheep had cellulitis at the site of inoculation, pleural hemorrhages, pneumonia, myocarditis, renal infarcts, glomerulitis, adrenal cortical necrosis, enteritis, focal splenic necrosis, polyarthritis and lymphadenitis. Vasculitis and thrombi were seen occasionally, suggesting that vascular changes, perhaps together with coagulopathy, had a role in pathogenesis. One of two experimental calves developed a slight fever, arthritis and minor inflammation of adrenal tissue. Calves seen less susceptible to the mycoplasma organism given intravenously than do goats or sheep.

Although marine vibrio wound infections and septicemia are being reported with increasing frequency, description of the histopathologic changes has been scanty. The histologic alterations in three patients with primary marine vibrio wound infections are presented. The lesions are characterized by intense acute cellulitis of the subcutis with much tissue destruction and extension into the adjacent dermis. The superficial dermis is devitalized and lacks an inflammatory cellular infiltrate. Subepidermal noninflammatory bullae are formed. Many organisms are seen both within the areas of intense acute inflammation and in devitalized areas. Organisms and inflammation are especially oriented around vessels, with associated acute vasculitis. It is concluded that the morphologic picture in marine vibrio wound infections is nonspecific yet characteristic.

A case of excessive heparin requirement during cardiopulmonary bypass is reported. A patient with sepsis secondary to a myocardial abscess require 13.5 mg x kg-1 of heparin to increase his activated coagulation time to a therapeutic level. This phenomenon might be due to individual variability, lupus vasculitis, septicaemia, repeated thromboembolic phenomenon with hypercoagulable state, or chronic disseminated intravascular coagulation with partial antithrombin deficiency.

Circulating immune complexes were determined with the 125I-Clq binding assay and the conglutinin binding assay in a prospective, longitudinal study of 40 patients with infective endocarditis, 34 patients with endocardial defects and nonseptic fever and 25 patients with septicemia without endocarditis. Fourteen patients with uncomplicated valvular lesions constituted a control group. Upon admission, 63 percent of the patients with infective endocarditis had a positive 125I-Clq binding assay versus 9, 12 and 7 percent, respectively, of the other three groups (p less than 0.001). The incidence of positive conglutinin binding assays became significantly higher during the course of infective endocarditis (53 percent) than during the course of nonseptic fever (21 percent), but, upon admission, this difference was not significant. The high incidence of Clq-binding immune complexes among patients with infective endocarditis could be attributed mainly to those patients with the characteristic features of subacute endocarditis. The incidence of circulating immune complexes in acute endocarditis was low and did not contribute to making the clinically important distinction from septicemia without endocarditis. A rise in the 125I-Clq binding assay levels during the course of infective endocarditis correlated significantly (p less than 0.01) with failure of antibiotic treatment. With the 125I-Clq binding assay, significantly higher levels were found in patients with signs of renal involvement of cutaneous vasculitis than in patients without these extracardiac manifestations of endocarditis. These results show that the determination of circulating immune complexes has clinical implications for both the diagnosis and the management of infective endocarditis and that circulating immune complexes are probably involved in the development of glomerulonephritis and vasculitis.

We reported a case of type II cryoglobulinemia involving glomerulopathy associated with HCV-induced liver cirrhosis. The patient was a 57-year-old woman. Her past history included chronic hepatitis at 51 years and rheumatoid arthritis at 53 years of age. At 46 years, an erythematous lesion appeared on her legs, which was diagnosed as allergic vasculitis by skin biopsy. At 50 years, proteinuria, hematuria and hypertension were recognized. The next year, the first renal biopsy was performed and showed membranoproliferative glomerulonephritis (MPGN). Recently, the edema of her legs has progressed, and the laboratory data showed proteinuria, hematuria, hypocomplementemia, rheumatoid factor positivity, and increase of monoclonal IgG kappa chain. The second renal biopsy revealed an endocapillary proliferative glomerulonephritis-like lesion with marked infiltration of monocytes and macrophages. The subendothelial deposit showed a fine fibril-like pattern. She was treated with steroids and double filtration plasmapheresis (DFPP) therapy, but the treatment was not very effective. She died of liver cirrhosis, which was probably induced by hepatitis C virus (HCV), and sepsis. Generally, the patients of type II cryoglobulinemia often showed HCV antibody positivity, pointing to HCV as an etiological factor. In this case, renal biopsy was performed twice in the same patient, and the histologic findings suggest the clinicopathological course of cryoglobulinemia.

We present a boy who had been under observation for 4 years, suffering since the age of nine from necrotizing vasculitis, which appeared during Proteus sp. sepsis. Complex treatment with antibiotics, large doses of steroids, antithrombotic and peripheral circulation improving drugs, as well as local drugs applied to the skin and oral cavity mucosa, resulted in a complete cure. This illness left some cosmetic skin defects on the face and extremities, a shortening of the tongue and malocclusion.

We describe a 41-year-old patient with adult-onset dermatomyositis who developed persistent pneumomediastinum and severe subcutaneous emphysema due to end-stage interstitial lung disease. The diagnosis of dermatomyositis was based on proximal muscle weakness, electromyographic findings of inflammatory myopathy, and positive findings on muscle biopsy. Low levels of creatine kinase elevation were found at the time of diagnosis (a form of dermatomyositis which has been associated with a poor prognosis). The patient had no signs of cutaneous vasculitis. Despite treatment with prednisone and azathioprine, she died of intercurrent gram-negative sepsis 15 months after the diagnosis of dermatomyositis.

We report 10 women and five men with papulonecrotic tuberculid, an uncommon form of cutaneous tuberculosis (TB). The mean age was 22.6 years (range, 2 1/2-35 years) at presentation. The Mantoux test was strongly positive in 13 patients. Five patients showed presumptive evidence of associated TB; in one case, the presence of TB was proven by culture. Response to anti-TB was dramatic in all cases. Clinical findings were similar to those previously published. We emphasize the simultaneous occurrence of erythema induratum, associated Takayasu's disease, possible associated phlebitic tuberculid, and clinical mimicry of acute bacterial endocarditis. The main histopathological findings obtained from 27 biopsy specimens included dermal necrosis (26 of 27 cases), a poorly formed granulomatous infiltrate (27 of 27 cases), vasculitis (11 of 27 cases), perivascular spongy edema (11 of 27 cases), and follicular necrosis or suppuration (five of 27 cases). A Ziehl-Neelsen stain was negative in all biopsy specimens. Immunohistochemical labeling revealed a preponderance of T-lymphocytes (UCHL-1+), monocytes-macrophages (S-100+), and Langerhans cells (ACT+), indicative of a type IV hypersensitivity reaction. B-lymphocytes (L26+) were sparse. Conditions that may be confused with PNT on clinical or histopathological ground include pityriasis lichenoides et varioliformis acuta, papular urticaria, papulopustular syphilide, miliary TB, septicemia, perforating granuloma annulare, chondrodermatitis nodularis, reactive perforating collagenosis, allergic granulomatosis, suppurative folliculitis, and infectious causes of palisading granulomas. Papulonecrotic tuberculid has distinct clinical, histopathological, and immunohistochemical features. Awareness of this entity is important since an appropriate diagnosis is necessary for the institution of timely curative treatment.

In the randomized autopsy material of 161 patients with rheumatoid arthritis (RA), a letal, generalized septic infection (GSI) was observed in 22 cases (13.66%). The GSI was accompanied by a pyarthros in 12 (7.45%) and no pyarthros in 10 (6.21%) cases. The clinical parameters of 22 septic RA patients were compared with 139 age and sex matched RA patients without GSI. The average age of septic patients decreased (p < 0.02), with low serum electrophoretic b-globulin level (p < 0.04), and high Waaler-Rose (p < 0.02) and Latex level (p < 0.004). The clinical parameters of 22 septic patients were compared with 76 age and sex matched RA patients without sepsis, vasculitis, or generalized secondary amyloidosis (GSA), and/or miliary epitheloid granulomas of tuberculous type (mT). The differences between the two groups of patients were the same, with a statistically more pronounced age difference (p < 0.005). 29 out of 161 patients (18.01 %) suffered from a clinically manifest diabetes mellitus (in 6 patients accompanied by sepsis), and 11 (6.83 %) from a clinically latent diabetes mellitus (in 2 patients accompanied by sepsis). There was no significant relationship between sepsis and manifest diabetes mellitus. The controlled and treated diabetes mellitus does not influence the frequency of lethal sepsis. Significant correlations were found between sepsis and latent diabetes mellitus (based on the histological detection of amyloid deposition localized to the islets of Langerhans (p < 0.02). 34 out of 161 patients (21.12%) suffered from a generalized secondary amyloidosis (in 3 patients accompanied by sepsis). There was no significant relationship between sepsis and generalized secondary amyloidosis. The thickness of adrenal cortex represents the effect of steroid therapy. Critical random check, using the Mann-Whitney tests, supports significance relationship between the adrenal cortex atrophy and fatal sepsis (p < 0.010). The follicular lymphoid depletion in the spleen represents the effect of immunosuppressive therapy. The size of lympho-follicles decreased significantly in sepsis (p < 0.004). The long term corticosteroid therapy and immunosuppressive represent a potential danger for sepsis.

Inflammatory conditions of the aorta may present with non-specific clinical features, including unexplained fever. Indium-111 labelled leucocyte imaging may be performed in such patients to look for the presence of occult sepsis or to assess the activity of a known vasculitis. Of approximately 1100 patients to undergo leucocyte scintigraphy for these indications over a 5 year period, three had focal leucocyte uptake in the aorta. The final diagnoses were: (1) periaortitis in Wegener's granulomatosis; (2) aortic dissection in giant cell arteritis; and (3) streptococcal aortitis with impending rupture. In all three cases the uptake was initially not thought to be in the aorta, but in bowel, a paravertebral abscess and in the lumbar spine respectively. Further imaging with CT and MRI led to the correct diagnoses. As the aorta is a rare site of focal leucocyte uptake, errors in image interpretation are likely. The rapid diagnosis of inflammatory conditions of the aorta is essential, however, as they may be life-threatening if unrecognized; therefore awareness of the aorta as a potential site of uptake is important. Urgent referral for further imaging is imperative in these cases as a false or delayed diagnosis may lead to avoidable morbidity and mortality.
