Fatal calcific uraemic arteriolopathy (CUA): a case report and review of the literature.

Calciphylaxis, now better known as Calcific uraemic arteriolopathy (CUA), is an uncommon condition characterised by small vessel calcification and occlusion with resultant painful violaceous skin lesions that typically ulcerate to form non-healing gangrenous ulcers. The syndrome is usually found in patients with renal failure. In this report we describe a 61 year old lady who developed lower limb ulceration secondary to calciphylaxis and discuss the current treatment options for this serious condition.

Histological appearances in post-partum de Quervain's disease.

Six patients who developed de Quervain's disease during pregnancy or within 12 months of childbirth were treated surgically. Histopathological examination of the tendon sheaths using alcian blue stain showed that myxoid degeneration was responsible for the thickening observed in the sheath. Characteristic intramural deposits of mucopolysaccharides were present, predominantly in the subsynovial region. Acute or chronic inflammatory changes were not seen. These findings were the same as those described in patients with de Quervain's disease unrelated to pregnancy or childbirth.

Use of pyrethroid impregnated tags in the control of sheep headfly disease.

Plastic tags containing 8.5 per cent w/w cypermethrin or 10 per cent w/w permethrin reduced the severity of damage caused to sheep by the headfly Hydrotaea irritans. A similar pattern of protection extended from the tagged ewes to their untagged lambs. Tags containing 8.5 per cent w/w fenvalerate failed to reduce the level of headfly damage in gimmers.

Evaluation of three synthetic pyrethroids in the control of sheep headfly disease.

Deltamethrin (0.01 per cent) applied to the heads of lambs and gimmers at 30 day intervals on two separate farms failed to control damage caused by the sheep headfly , Hydrotaea irritans. Permethrin (0.1 per cent) applied to gimmers at monthly intervals achieved a slight reduction in severity of damage but protection did not extend beyond 14 days. Polyvinyl chloride tags containing 8.5 per cent cypermethrin reduced damage in gimmers to a very low level with protection lasting throughout the summer. Weight gains of lambs suffering headfly damage were significantly less than unaffected lambs.

Intercellular spaces and cell junctions in endometrial glands: their possible role in menstruation.

Intercellular spaces and cell junctions in human endometrial glands were studied by elctron microscopy following different methods of fixation. The size of the spaces, known to alter during the cycle, was found to depend also on the method of fixation. Various intrusive cells and different types of cell debris were seen in these spaces. The three most widely recognized cell junctions (desmosomes, tight junctions and gap junctions), were all most abundant near the cell apices. The possible significance of these findings in elucidating the cellular mechanism of menstruation is discussed.
