Solitary involvement of the fourth thoracic vertebral body with eosinophilic granuloma and development of incomplete paraparesis.

This is a report of the case of a 9-year-old boy with solitary involvement of the fourth thoracic vertebral body with eosinophilic granuloma and development of neurologic deficits. Ventral decompression of the spinal cord, removal of the tumor tissue, and anterior arthrodesis succeeded in preventing an increase of the kyphotic deformity of the vertebral body. Complete reversal of the neurologic deficits was seen in the further course.

[Static and dynamic infrared thermometry and thermography in malignant melanoma of the uvea and conjunctiva].

BACKGROUND: Thermometry and -graphy prove asymmetries of the circulation. Contact-free thermometry of the cornea is applied to find out whether this method can contribute to differential diagnosis of ocular melanomas. MATERIALS AND METHODS: Under standardized conditions the temperature of the cornea was measured in 30 patients with malignant melanoma of the choroid and the conjunctiva and 35 healthy subjects. The instruments were a handpyrometer (HPM, Messgerätewerk, Magdeburg) and the thermovision camera of AGA Infrared System, Sweden, with dynamic recording in colour. RESULTS: In healthy subjects there are no significant asymmetries in temperature under standardized conditions. The temperature of the cornea is elevated in both malignant melanomas of the choroid and the conjunctiva. CONCLUSIONS: Thermometry and -graphy of the cornea can contribute to the differentiation of malignant ocular melanomas from other ophthalmological diseases. They are also suited in long term observation of the course of the melanomas.

Effective propagation of various type D retroviruses in human lymphoblastoid Raji cells.

Type D retroviruses belong to viruses which often have a low titer in virus-reproducing cell-systems. In search of better conditions for virus propagation, Raji cells (an EBV-genome carrying human B-cell line) were infected with different isolates of type D retroviruses. as demonstrated by electron microscopy all of the viruses showed a very good and stable virus production during long term cultivation on Raji cells.

[The cartilage in nuclear magnetic resonance tomography].

Comparison of MRI tomograms with anatomic sections shows that the limits of the joint cartilage do not correspond to the hitherto assumed zone of the more intensive signal. This intensive signal may be caused merely by the surface of the cartilage. Considering its extent, the signal-free zone bordering on this zone should also be cartilage. Since, e.g., in the knee, there is no subchondral substantia corticalis and, as is clearly recognizable in the anatomic section, bone marrow extends as far as the cartilage, this signal-poor zone should also correspond, at least in part, to cartilage. It is conceivable that the boundary areas in the MRI tomogram (in this case the cartilage surface) are demonstrated and that the signal behavior of the hyaline joint cartilage is not uniform and applicable to all sections. This also applies to fibrous cartilage.

Acute oral, dermal, and inhalation studies.

By appropriate testing procedures, it has been demonstrated that the compounds used as fluorescent whitening agents (FWAs) have a very low order of systemic toxicity in acute experiments. No evidence of dermal toxicity has been found. The full chemical names of the fluorescent whitening agents (FWAs) investigated in this study are listed below. They have been numbered for easy identification and classified by chemical groups.
