Angioid streaks in homozygous beta thalassemia.
One hundred patients with homozygous beta thalassemia (62 had beta thalassemia major and 38 had beta thalassemia intermedia) were examined by ophthalmoscopy for angioid streaks. Angioid streaks were found in 20 patients from both the beta thalassemia major and beta thalassemia intermedia groups (nine and 11 patients, respectively). A positive correlation was found between age and angioid streaks (P = .0017), as was a difference in the prevalence of angioid streaks between the two forms of the disease (P = .079). Additionally, a significant correlation was noted between chelating therapy and the prevalence of angioid streaks (P = .039). However, using multivariate analysis to correct for the effects of age, the correlation of angioid streaks with the form of disease disappeared, whereas the level of significance between chelation therapy and angioid streaks was reduced (P = .05). The high frequency of angioid streaks observed in patients with beta thalassemia and the severe complications observed in one patient render a thorough ophthalmoscopic examination and follow-up of such patients necessary for both early diagnosis and possible therapeutic intervention.

Autoantibodies in systemic lupus erythematosus and normal subjects.
The presence of various antibodies in serum samples from patients with systemic lupus erythematosus (SLE) and from healthy subjects was investigated by ELISA, using a panel of natural antigens. Fifty-eight serum samples from 58 healthy women and 50 serum samples from 30 patients with active SLE were tested with 9 natural antigens (ds-DNA, actin, tubulin, thyroglobulin, myosin, myoglobin, human transferrin, human interferon a and BSA FV). It was found that the proportion of positive sera from healthy women at a dilution of 1/20 was almost the same as that of lupus sera at a dilution of 1/150 for nearly all antigens, while at a dilution of 1/150 the proportion of positive sera from patients with SLE was significantly higher for nearly all antigens. In lupus sera a high degree of correlation was observed between titers of anti-DNA and titers of the other antibodies. One hundred eighty-eight serum samples from 53 SLE patients, taken during exacerbation and remission of the disease were tested with ds-DNA, actin and tubulin. Antibodies (IgG) to ds-DNA actin and tubulin were found in the majority of serum samples taken during the active phase of the disease. On the other hand, very few serum samples taken during remission were found to be positive. A high degree of correlation was found between the OD of anti-actin/anti-ds-DNA (r = 0.769) and anti-tubulin/anti-ds-DNA (r = 0.829). In a competitive enzyme immunoassay for DNA, actin, tubulin, myosin and thyroglobulin, a high degree of inhibition was observed with the homologous antigens.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical utility of a two-site immunoradiometric assay for creatine kinase-MB in the detection of perioperative myocardial infarction.
In 144 patients, creatine kinase MB was measured serially at 0, 8, 16, 24, 48, and 72 hr using a two-site immunoradiometric assay (IRMA). Cardiac enzymes were also measured, including SGOT, LDH, total CPK, and CK-MB by electrophoresis. The presence of perioperative myocardial infarction (poMI) was established in 24 patients by the appearance of new electrocardiographic Q waves and/or new wall motion abnormalities detected by radionuclide ventriculography. In patients without poMI, CK-MB (IRMA) was elevated (6.4 +/- 4.9 equivalent units per liter) at 0-8 hr but decreased to 3.4 +/- 1.3 EU/l by 16 hr. In patients with poMI, peak values occurred at 16-24 hr (21.0 +/- 19.8 EU/l). Using a threshold value of 8.5 EU/l, patients with poMI could be distinguished from those without with 97% accuracy (sensitivity = 88%, specificity = 99%). The CK-MB (IRMA) was more reliable than the other enzyme assays, for which we used both empirically elevated threshold values based upon previous experience, and also threshold values retrospectively optimized for the study population. We conclude that the CK-MB (IRMA) can serve as a valuable postoperative screening test for poMI.

Renal pseudotumor simulating malignancy in a patient with Adamantiades-Behçet's disease: case report and review of the literature.
Adamantiades-Behçet's disease is a multisystem recurrent syndrome with vasculitis being the underlying histopathological lesion. We report on a patient with Behçet's disease who developed a renal mass raising the suspicion of a malignant neoplasm. The pathologic examination revealed an inflammatory pseudotumor. The concurrent presentation of these two entities seems to be more than coincidental.

A Java-based electronic healthcare record software for beta-thalassaemia.
BACKGROUND: Beta-thalassaemia is a hereditary disease, the prevalence of which is high in persons of Mediterranean, African, and Southeast Asian ancestry. In Greece it constitutes an important public health problem. Beta-thalassaemia necessitates continuous and complicated health care procedures such as daily chelation; biweekly transfusions; and periodic cardiology, endocrinology, and hepatology evaluations. Typically, different care items are offered in different, often-distant, health care units, which leads to increased patient mobility. This is especially true in rural areas. Medical records of patients suffering from beta-thalassaemia are inevitably complex and grow in size very fast. They are currently paper-based, scattered over all units involved in the care process. This hinders communication of information between health care professionals and makes processing of the medical records difficult, thus impeding medical research. OBJECTIVES: Our objective is to provide an electronic means for recording, communicating, and processing all data produced in the context of the care process of patients suffering from beta-thalassaemia. METHODS: We have developed - and we present in this paper - Java-based Electronic Healthcare Record (EHCR) software, called JAnaemia. JAnaemia is a general-purpose EHCR application, which can be customized for use in all medical specialties. Customization for beta-thalassaemia has been performed in collaboration with 4 Greek hospitals. To be capable of coping with patient record diversity, JAnaemia has been based on the EHCR architecture proposed in the ENV 13606:1999 standard, published by the CEN/TC251 committee. Compliance with the CEN architecture also ensures that several additional requirements are fulfilled in relation to clinical comprehensiveness; to record sharing and communication; and to ethical, medico-legal, and computational issues. Special care has been taken to provide a user-friendly, form-based interface for data entry and processing. RESULTS: The experience gained through the use of JAnaemia in 4 Greek hospitals reveals a significant contribution towards (1) improvement of the quality of the data being recorded, since data entry is guided by appropriate forms, (2) easier cooperation between physicians, who share a common information repository, and (3) increased processing capabilities, which facilitate medical research. CONCLUSIONS: JAnaemia appears to be a useful tool, which can improve the quality of care offered to beta-thalassaemic patients in Greece.

Asymptomatic pericarditis in Adamantiadis-Behçet's disease.
Pericardial involvement in Adamantiadis-Behçet's disease (ABD) is uncommon. A 14-year-old boy presented with fever of unknown origin, as the initial and only manifestation of his disease. Other features were leukopenia, abdominal lymphadenopathy and asymptomatic pericarditis, which is a very rare finding of the disease. A review of pericarditis is presented.
