Langerhans cell histiocytosis syndromes have been described as encompassing a range of disorders, such as eosinophilic granuloma, Letterer-Siwe syndrome and Hand-Schüller-Christian disease. These disorders have been mainly diagnosed at early ages of life and are relatively rare entities in adult age groups. In this study, we aimed to retrospectively evaluate the patients with Langerhans cell hi...

Several groups of investigators have shown that the induction time for experimental murine amyloidosis may be accelerated by passive transfer ofviable spleen cells or subcellular fractions of spleen cells from casein-treated donors to isogeneicrecipients (Werdelin and Ranl0v, 1966; Hultgren, Druet, and Janigan, 1967; Dreher and Letterer, 1970). On rare occasions the recipient mice appear to hav...

A 10-year-old boy presented with torticollis and neck pain for 2 months without fever. His physical examination showed torticollis and limitation of flexion/extension and cervical rotation without neurological deficit. Family and past histories were unremarkable. Cervical spine radiographs showed a cervical scoliosis with loss of the normal cervical lordosis and partial collapse of C3 vertebral...

We have investigated the secretory function of cell suspensions from bone eosinophilic granulomas surgically collected in two patients with histiocytosis X. Unseparated cell preparations spontaneously produced interleukin 1 (IL-1) and prostaglandin E2 (PGE2). In order to ascertain that this secretion was due to the characteristic Langerhans cell-like histiocytosis X cells predominantly found in...

Latent electrostatic discharge (LESD) damage sites are normally identified and analyzed after the damaged oxide has been transformed from a low to a high level leakage. Failure analysis typically focuses only on the primary rupture site, neglecting the remaining LESD damage sites. The purpose of this work is to present a new method of analysis which allows compromised oxides to be rapidly ident...

A retrospective study was undertaken of 1005 normal contrast-enhanced head computed tomographic (CT) scans in children to determine normal standards for pituitary stalk diameter, basilar artery diameter, and their ratio for age and gender. The pituitary stalk enlarges with age, and girls have larger stalks than do boys after age 8. The pituitary stalk-to-basilar artery ratio is easily estimated...

In three patients with histiocytosis X of bone with orbital involvement, CT scans were reviewed. Consistent findings included a destructive lesion of the lateral wall of the orbit with a large soft-tissue component that extended into the extraconal space, the ocular adnexa, and the infratemporal fossa. The greater wing of the sphenoid was eroded in all cases, with epidural extension into the mi...

A 23 yr old man was admitted suspected of having a liver disease because of marked elevation of the serum alkaline phosphatase. A biopsy of the liver was without cholestasis. A skin biopsy of a papule was compatible with eosinophilic granuloma. Over a few months the patient developed severe restrictive lung disease. The elevation of the serum alkaline phosphatase was probably due to diffuse bon...

Eosinophilic infiltration, localised or diffuse, of the gastrointestinal tract cannot be regarded as a definitive diagnosis; neither can a classification of disease, in which this is a feature, be founded on the degree or site of such infiltration. Eosinophilia is merely a manifestation of inflammation, often with an allergic basis, and accompanies a number of well defined clinicopathological c...

In 1973, a 10 year old boy presented with numerous bilateral lung nodules, diagnosed as histiocytosis X by open lung biopsy. The patient was treated with prednisone until 1984. In 1993, he developed severe pain in the neck. A biopsy of the spine revealed the same tumour morphology as was seen in the lung in 1973. Immunohistological examination of the former and present biopsy led to the definit...
