Multifocal fibrosis is a rare condition occurring at any age and characterized by chronic inflammation, soft tissue proliferation and subsequent fibrosis of various vascular connective tissues. Following diagnosis in a 43-year accountant with multiple vascular lesions, the patients was treated successfully with azathioprine and steroids over a period of 3 years. Fatigue and sweating, serologic ...

An in vitro test for the differentiation of trachoma strain isolates was described. The method was based on absorption of trachoma antiserum followed by immunofluorescent staining of individual trachoma strains. Nineteen trachoma strains were studied; two main types were identified. Evidence for quantitative and qualitative antigenic variation between the two types was presented. The limitation...

Certain of the serological factors which vary with the individual have been reported,t together with data supporting the idea that age, sex, and blood group differences show some correlation with the antibody titers measured. This supplementary note deals with one of the antigen-antibody systems included in the former study, the essential feature here being the significance of the host origin o...

S ALINE AGGLUTINATION REACTIONS of variable strength among Rh positive bloods were reported soon after the discovery of the Rh factor.”2 Wieners suggested that these D variant types were determined by special “intermediate” Rh genes and Stratton2 postulated that this weak D antigen was elaborated by a new allele, D’, at the D-d locus. The only blood types which could he classified as DL variant...

It has long been known that the serum of certain leprosy patients gives positive reactions with tests for syphilis. These reactions have not been understood and have been interpreted as biologic ‘(false positives.” The reason for this interpretation undoubtedly lies in the widespread assumption that only in syphilis and in closely related diseases, such as yaws and bejel, are serum reactions wi...

Abstract We conducted a serologic survey among dogs and cats in Italy to detect antibodies against severe acute respiratory syndrome virus 2 (SARS-CoV-2). found that SARS-CoV-2 seroprevalence was higher (16.2%) than (2.3%). In addition, animals living close contact with SARS-CoV-2–positive owners.

BACKGROUND Serologic testing for herpes simplex virus type-2 (HSV-2) is being implemented in sexually transmitted disease (STD) clinics. GOAL To determine the performance characteristics of two HSV-2 type-specific serologic assays in a public health laboratory. STUDY DESIGN Sera stored from a cross-sectional study were tested with the Meridian Diagnostics and Focus Technologies HSV-2 ELISA ...

Ulcerative colitis (UC), a chronic inflammatory bowel disease, occurs in genetically susceptible individuals who mount inappropriate immune responses to endoluminal antigens. Serologic and genetic markers have shown great potential for clinical application in Crohn's disease (CD), particularly for prognostication. However, their use is not as well established in UC. The aim of this paper is to ...

BACKGROUND Bartonella cat scratch disease is classically a febrile illness, in conjunction with lymphadenopathy and cat exposure. OBJECTIVE To report 2 atypical cases of cat scratch disease with only blurred vision and headache. DESIGN Case reports. SETTING University hospital. PATIENTS Two young adults with unilateral blurred vision, retro-orbital headache, and a positive Bartonella he...
