Common variable immunodeficiency disorders (CVID) are a group of heterogeneous conditions that have in common primary failure of B cell function, although numerous T cell abnormalities have been described, including reduced proliferative response and reduced regulatory T cells. This study compared the T cell phenotype of CVID patients subdivided into(More)
An arthrographic appearance, confidently diagnosed as synovial chrondromatosis, showed no abnormality at surgery. This experience prompted further investigation which led to the conclusion that a normal variant of the suprapatellar pouch may be confused with synovial masses. Single or multiple pseudomasses in this region may relate to the presence of an(More)
Autoimmune lymphoproliferative syndrome (ALPS) is a disorder of dysregulated lymphocyte homeostasis. Biomarkers including elevated CD3+TCRαβ+CD4-CD8- double negative T cells (TCRαβ+ DNT), IL-10, sCD95L and vitamin B12 can be used to differentiate between ALPS and common variable immunodeficiency (CVID) patients with an overlapping clinical phenotype. We(More)
Eccrine porocarcinoma is a malignant tumor of eccrine sweat glands. It is a very rare, slow growing tumor and clinically resembles other skin cancers. We report a case and review its clinical and pathological features. These tumors have a propensity for local recurrence, and wide excision with negative margins is recommended.
Chronic mucocutaneous candidiasis (CMC) is characterized by recurrent and persistent superficial infections, with Candida albicans affecting the mucous membranes, skin and nails. It can be acquired or caused by primary immune deficiencies, particularly those that impair interleukin (IL)-17 and IL-22 immunity. We describe a single kindred with CMC and the(More)
BACKGROUND AND OBJECTIVES Patients attending sexually transmitted disease (STD) clinics are frequently screened for gonorrhea and chlamydial infection. To determine the efficiency of these screening efforts as a component of STD control, we evaluated treatment outcomes of patients with positive cultures who had not received presumptive treatment at their(More)
B1 B cells represent a unique subset of B lymphocytes distinct from conventional B2 B cells, and are important in the production of natural antibodies. A potential human homologue of murine B1 cells was defined recently as a CD20(+) CD27(+) CD43(+) cell. Common variable immunodeficiency (CVID) is a group of heterogeneous conditions linked by symptomatic(More)
