There is sufficient evidence of the capacity of silica to induce autoimmunity in patients with some type of genetic susceptibility. There are several autoimmune diseases related to this exposure (rheumatoid arthritis, Sjögren's syndrome, sarcoidosis, systemic sclerosis). Nodular silicosis (clinical expression of this exposure in lungs) generates apoptosis, inflammation, loss of tolerance and a ...

An adult woman developed polymorphic post-transplant lymphoproliferative disorder (PTLD) 58 months after unrelated cord blood transplantation. She was treated successfully with chemotherapy and radiation therapy but presented with lymphadenopathy and splenomegaly 74 months after transplantation. A lymph node biopsy confirmed the diagnosis of nodular sclerosis type Hodgkin lymphoma (classical Ho...

Non-cirrhotic portal hypertension is an unusual but potentially serious liver disorder in human immunodeficiency virus-infected patients with prolonged exposure to didanosine. Due to its rarity, the diagnosis is often delayed. It is postulated that didanosine contributes to obliterative portal venopathy and causes portal hypertension. Affected patients may present with abnormal liver function o...

Autoimmune hemolytic anemia (AIHA) is rarely seen in Hodgkin lymphoma (HL) patients, with a reported incidence of 0.2–4.2%.1-3 Sporadic case reports and reviews have shown that when AIHA occurs in HL patients, it happens mostly at stages III and IV of nodular sclerosis HL (NSHL) or mixed cellularity HL (MCHL).4 We present a case of AIHA at the time of diagnosis of classic HL, stage IIIB, with a...

Calcific aortic valve disease (CAVD) is a leading cardiovascular disorder in the elderly. Diseased aortic valves are characterized by sclerosis (fibrosis) and nodular calcification. Sclerosis, an early pathological change, is caused by aortic valve interstitial cell (AVIC) proliferation and overproduction of extracellular matrix (ECM) proteins. However, the mechanism of aortic valve sclerosis r...

Although involvement of the heart by malignant lymphoma is relatively common, it is unusual to be detected premortem. We report a case of Hodgkin's lymphoma who presented with systemic signs and symptoms including abdominal distension, weakness, pallor, chills and fever, hepatosplenomegaly and generalized lymphadenopathy as well as signs of heart failure. Echocardiography revealed lucent myocar...

Light microscopic examination of the kidneys in 170 patients with multiple myeloma revealed three from patients without diabetes with glomerular nodules that were indistinguishable from those of diabetic glomerular sclerosis. Electron microscopic studies showed the nodules to be deposits of fine-grained material that corresponded to precipitations of protein but lacked the basement-membrane-lik...

Localized cutaneous nodular amyloidosis (LCNA) is the rarest form of localized cutaneous amyloidosis. In patients with LCNA, local plasma cells secrete immunoglobulin light chains called amyloid L via an unknown mechanism. LCNA has been associated with autoimmune connective tissue diseases such as most commonly Sjögren syndrome. A few reported cases of LCNA are associated with limited systemic ...

OBJECTIVE Surgical intervention can result in complete seizure remission rates of up to 80% in patients with temporal lobe epilepsy with hippocampal sclerosis (TLE-HS). However, certain patients cannot be treated surgically for various reasons. We analyzed the very long-term clinical outcomes of patients with TLE-HS who could not be treated surgically. METHODS Subjects were selected from amon...
