ceroid/hemorrhage

Intraplaque hemorrhages are mainly related to inward neoangiogenesis, initiated from the adventitia by lipid-dependent outwardly convected signals, and by the immaturity of these neovessels, allowing leaks and hemorrhages. Repeated intraplaque hemorrhages play a major role in the evolution of

In an endometrial curettage specimen, taken from a 67-year-old woman with post-menopausal bleeding, the endometrium was replaced by aggregates of swollen histiocytes filled with yellowish-brown pigment. Histochemical and ultrastructural examination of the specimen revealed that the pigment was of

Chediak-Higashi syndrome is characterized by oculocutaneous albinism, a bleeding tendency and severe recurrent infections. Age-dependent formations of autofluorescent ceroid-like substances have been noted in a variety of tissues. In this study, we isolated an autofluorescent ceroid-like aggregate

Acne and hirsutism are common findings in girls with juvenile neuronal ceroid lipofuscinosis (JNCL). A study on their hormonal status was conducted to investigate the mechanisms underlying these symptoms. Sixteen girls with JNCL entered the study. Ten of the girls had periodic menstruation, while

Three cases of ceroid granulomas of the female genital system are presented, involving the cervix in two and lesions in the ovaries and bowel serosa in the other. Ceroid granulomas are unusual and interesting lesions formed when suitable substrates accumulate within macrophages to such an extent

The Hermansky-Pudlak Syndrome (HPS) is a rare autosomal recessively inherited triad of oculocutaneous albinism hemorrhagic diathesis and accumulation of ceroid in tissues. This article comprising the published reports of 232 patients is extended by the personal observation of a 7-year-old boy with

The Hermansky-Pudlak syndrome (HPS) is an autosomal recessive disease characterized by a triad of oculocutaneous albinism, accumulation of auto-fluorescent ceroid-like pigments within macrophages, and bleeding tendency due to a storage pool disease of the platelets. We report an autopsy case (39y,

Five patients with Hermansky-Pudlak syndrome: storage pool deficiency, albinism and ceroid containing bone marrow macrophages and three patients with uncomplicated storage pool deficiency were treated with cryoprecipitate from 16 donors. Within 2 h of transfusion, bleeding times decreased towards a

OBJECTIVE The authors conducted a phase I study of late infantile neuronal ceroid lipofuscinosis using an adenoassociated virus serotype 2 (AAV2) vector containing the deficient CLN2 gene (AAV2(CU)hCLN2). The operative technique, radiographic changes, and surgical complications are

Atherothrombotic diseases are still major causes of inability and mortality and fighting atherothrombosis remains a public health priority. The involvement of repeated intraplaque haemorrhages (IPH) in the evolution of atherothrombotic lesions towards complications was proposed as early as 1936.

OBJECTIVE Previously, we demonstrated that activated inducible NO synthase (iNOS)-expressing foam cells in human carotid plaques often produce autofluorescent (per)oxidized lipids (ceroid). Here, we investigate whether intraplaque microvessels can provide foam cells with lipids and trigger

Pseudomelanosis duodeni, speckled black pigmentation of the duodenal mucosa, presents a striking appearance at endoscopy. Among the 14 reported cases there is a predominance of black women greater than 40 years old, but it can occur in any race and age group. There is no known association with

Hermansky-Pudlak syndrome (HPS) is an autosomal recessive disorder characterized by oculocutaneous albinism (OCA), platelet storage pool deficiency, and ceroid lipofuscin deposition. Sequelae including pulmonary fibrosis, colitis, and hemorrhagic diathesis can impact obstetric management. An

Platelets from patients with the Hermansky-Pudlak syndrome (albinism, accumulation of ceroid-like pigment in bone marrow macrophages and mild hemorrhagic symptoms) and aspirin-treated normal platelets fail to develop irreversible secondary waves of aggregation when exposed to aggregating agents on
