[Calcium alginate as a nasal pack].

Alginates are highly absorbent, gel-forming materials with haemostatic properties. The aim of this study was to compare calcium alginate to Telfa as a postoperative nasal pack in a prospective randomised clinical trial. Eighty two patients entered the trial. There were 55 males and 27 females whose ages ranged from 13 to 74 years (mean 34.7 years). Immediate postoperative bleeding was controlled in all cases irrespective of the pack used. There was no difference in the incidence of postoperative complications between the two groups. Calcium alginate is a safe and effective alternative to Telfa as a postoperative nasal pack.

The influence of calcium alginate haemostatic swabs upon operative blood loss in adenotonsillectomy.

Although adenotonsillectomy is regarded as a minor procedure, it has been shown that 18% of patients may experience an operative blood loss of 10-20% of the total blood volume. The aim of this study was to determine whether calcium alginate haemostatic swabs reduce operative blood loss in adenotonsillectomy. Seventy-two patients (ages 2-12 years) entered a prospective trial in which the operation was performed either with normal gauze swabs or calcium alginate swabs. Thirty-six children were randomized to each group. The mean blood loss was found to be 34.9 ml (2.07% of total blood volume) and 47.8 ml (2.97% of total blood volume) respectively. Although there was no significant reduction in operative blood loss using calcium alginate, in both groups the blood loss was much smaller than that stated by the majority of previous workers.

Superficial malignant schwannoma on the face: a case for early radical surgery.

A case of superficial epithelioid schwannoma is presented. The lesion arose as a skin papule in the infra-orbital region and recurring repeatedly over a five-year period, caused significant local morbidity without metastasis. Radical surgery was delayed in the hope of preserving binocular vision. The similarity of this tumour with a rare variant of malignant melanoma, the neurotropic melanoma, is discussed.
