Bullous dermatosis associated with latent diabetes

A bullous dermatosis leaving brownish pigmented scar formation could be observed on the legs of a female patient suffering from latent diabetes. The immunofluorescence method failed to demonstrate specific immunoglobulin deposition of the skin. Histologically, subepidermal localization of the vesicles and diabetic angiopathy of dermic vessels could be seen. It is concluded that the bullous dermatosis of diabetics represents a special form of diabetic dermopathy.

Dichroic absorption of m centers as a basis for optical information storage

The rotational properties of M centers in alkali halides are investigated as a possible basis for storing information. Measurements using a NaF matrix indicate that high storage density, high writing efficiency, thermal stability, and nondestructive readout are attainable in a practical situation at room temperature or lower. However, temperatures below 300 K are necessary for fatigue-free operation in the present material.

Study of circulating immune complexes in atopic dermatitis

The authors examined sera from 92 patients (78 adults, 14 children) with atopic dermatitis (AD), for the presence of circulating immune complexes (CIC). Using the PEG precipitation technique they found an increase in CIC total protein. In the quantity of precipitated proteins, elevated IgA and IgG levels and decreased C3 in CIC were measured. Neither the acute nor the subacute stage of the disease, nor skin involvement, correlated with CIC. In increased content of CIC was found in patients who had AD with associated disease recurrent infections, recurrent conjunctivitis, asthma, allergic rhinitis) and especially with pustulosis varicelliformis Kaposi, i.e. eczema herpeticatum. The T lymphocytes, together with other surface complement receptor-positive cells, are able to induce CIC production and keep them in solution.
