The present study has shown that in some patients parathyroid cell allotransplantation may be considered a method of treatment for permanent hypoparathyroidism after thyroid surgery. Graft function and/or survival did not depend on the baseline viability or secretory activity of cultured cells used for transplantation.

Serum and salivary IgA and IgG antigliadin antibodies were determined by an enzyme-linked immunosorbent assay in 18 children with villous atrophy and 30 children on a gluten-free diet for coeliac disease in whom normal intestinal mucosa was found. Serum IgA anti-endomysium antibodies were also determined by an immunofluorescence method in these children. Serum IgG antigliadin and IgA anti-endomysium antibodies had the highest sensitivity (100 and 94.4%, respectively), followed by serum IgA antibodies to gliadin (72.2%), salivary IgA antigliadin (61.2%) and IgG antigliadin (50%) antibodies. The highest specificity was found for serum IgA anti-endomysium (100%) and IgA antigliadin (96.6%) antibodies and salivary IgA and IgG antigliadin antibodies (93.3%), while serum IgG antigliadin antibodies were found to be least specific (63.3%).

Summary. The gross anatomy and the histological appearances of the spinal cord were studied in 120 patients who died in the Metropolitan Rehabilitation Centre at Konstancin as a result of a spinal injury. Three varieties of lesion were fo und:I. Total disorganisation of the spinal cord at the site of trauma. 2. Total disorganisation of the cord at the site of trauma associated with pipelike necrosis extending up and down fr om the main injury. This longitudinal cylindrical-pipelike necrosis is described in this paper as 'traumatic haemorrhagic cavitation'. 3. Partial spinal cord necrosis localised to the area of supply of intraspinal arteries. The possible vascular mechanisms of traumatic spinal cord injury, resembling the changes observed in experimental animals, are discussed.

A 10-year-old boy was evaluated for fever, weight loss, uveitis, normocytic, normochromic anemia, renal insufficiency, and hypergammaglobulinemia of 8 weeks' duration. Infectious and neoplastic causes of fever were excluded. A renal biopsy performed in the 4th week of disease revealed diffuse plasmocytic interstitial nephritis. No treatment was prescribed and the patient was transferred to another hospital. Because clinical symptoms and renal insufficiency were still present, in the 8th week of disease a second biopsy was performed, which showed lympho-monocytic interstitial nephritis. At the same time, phenotypic analysis of peripheral blood mononuclear cells was carried out, revealing a significantly decreased number of CD3(+), CD4(+), and CD3(+)/CD8(+) cells, increased non-T CD3(-)/CD8(+) and CD56(+) NK cells, and decreased "naïve" (CD45RA(+)/CD4(+)) and memory (CD45RO(+)/CD8(+)) T lymphocytes. A 6-month course of oral prednisone was prescribed. Clinical symptoms and laboratory findings quickly returned to normal values. After 13 days of corticosteroid therapy, a second phenotypic analysis of peripheral blood mononuclear cells was performed, which revealed normalization of CD3(+), CD4(+), and CD3(+)/CD8(+) cells as well as proportions of non-T CD8(+) and CD56(+) NK lymphocytes, "naïve" and memory cells. This case shows spontaneous evolution of tubulointerstitial infiltrates from plasmacytic to lympho-monocytic, profound disturbances of the immunological system, and the beneficial effect of corticosteroids on both the clinical course and immunological disturbances.
