Evaluation of the quality of surgical gloves among four different manufactures.

A randomized trial was conducted to evaluate the quality of four different brands of surgical gloves in terms of the perforation rate, ventilation, fitness, allergic reaction, elasticity, thickness, powder, and satisfaction. Gloves of four different manufactures which were used by various medical centres were distributed to participants according to a computer-generated randomization table. A structured questionnaire was self-administered by volunteers immediately after the surgical procedure to gather the information from participants, including the demographic data, allergy history, length of use, and variables of quality measures. Two brands, A and D, were significantly inferior to the best manufacture among the four, B, in terms of the ventilation, elasticity, and thickness, odds ratios ranging from 6 to 24, p < 0.05. For the amount of corn starch powder and satisfaction, all three other brands were inferior to brand B, odds ratios ranging from 6 to 44, p < 0.05. Gloves worn longer than 2 hours had a slightly higher perforation rate post procedures (11.5% vs. 2.1%, p = 0.048). The rate of latex allergic reaction was not significantly different between surgeons (8.3%) and the others (6.7%). No difference of the allergic reaction rate was found between subjects with allergy history (7.7%) and those without the history (7.5%). The quality of surgical gloves differs from brand to brand. The government and institutions should take the responsibility of monitoring the quality of surgical gloves in order to provide a safer and more comfortable environment for the surgical personnel and patients.

Oestrogen receptor assay of breast cancer by immunocytochemistry of fine needle aspirates.

Sixty-five patients with operable breast cancer were studied to assess the reliability of immunocytochemical analysis of oestrogen receptor (ER-ICA) in specimens obtained by percutaneous fine needle aspiration. Results obtained with the commercially available ER-ICA kit were compared with those obtained by the routine biochemical radioligand assay of oestrogen receptor (ER) on excised tumour specimens. Fifty-two of 65 percutaneous aspirates were evaluable. Of these, thirty-five (67%) were ER positive by the radioligand method. ER-ICA was found to be a reliable method for oestrogen receptor assay, with a high concordance (90.4%) between it and the radioligand essay. The ER-ICA assay had a sensitivity of 89%, specificity of 94%, positive predictive value of 97% and negative predictive value of 80%. ER-ICA assay performed on material obtained by fine-needle aspiration is a reliable method of ER assay. It can replace formal biopsy for patients with inoperable primary tumours or accessible metastases.
