The prevalence of antinuclear antibodies (ANA) was investigated in the sera from patients with habitual abortion (HA) and in normal (NP) and toxemic pregnancies (TP). ANAs were more prevalent in patients with HA (30%) as compared with TP (15%) and the control group (6.6%). Only one patient, from the HA group, fulfilled four criteria for systemic lupus(More)
Leukemias rarely debut by pleural involvement as the first manifestation of the hematologic malignancy. This complication is most commonly seen in solid tumors such as carcinomas of the breast, lung, gastrointestinal tract and lymphomas. We present a case of a 66 year old male who presented with a pleural leukemic infiltration of his undiagnosed Acute(More)
Papillary thyroid carcinoma frequently metastasizes to regional lymph nodes. However, cervical lymph node metastasis as a sole manifestation of occult papillary thyroid carcinoma is rarely observed. Ectopic thyroid is an uncommon condition defined as the presence of thyroid tissue at a site other than pretracheal area. Approximately 1-3% of all ectopic(More)
In 1986, we diagnosed and treated 4 patients, all members of 1 rural family, who presented simultaneously with a polymyositis-like syndrome, anticytoplasmic antibodies (on HEp-2 cells), and precipitating antibodies of anti-Jo-1 and anti-PM-Scl specificities. Serum samples from these patients reacted by immunodiffusion against serum from a rodent that had(More)
INTRODUCTION The total number of patients with Human Immunodeficiency Virus (HIV) is 33 million, with 2.7 million new infections in 2007(1). Puerto Rico has an increasing prevalence trend of Diabetes Mellitus of 12.8% in 2010(3). As treatment of HIV continues to develop, and access to therapy improves, the incidence of HIV associated diabetes is bound to(More)
Autoimmune thyroid diseases may occur in association with systemic rheumatic disorders, and usually they show a high prevalence of antithyroglobulin and antimicrosomal antibodies. We report 6 patients with the clinical association of systemic lupus erythematosus (SLE) and hyperthyroidism. Of interest, in 5 of the 6 patients (83%), we found an antibody(More)
The prevalence of anti-SSA (Ro) antibodies was investigated in 126 patients with various systemic rheumatic diseases and in 77 normal subjects. Also, we studied the relationship between these autoantibodies and the clinical features of our patients with SLE. Anti-SSA (Ro) occurred with a frequency of 14% in SLE but was not associated with specific clinical(More)
