The aims of this study were: to determine whether there is an increased incidence of iron deficiency in paediatric otolaryngology inpatients compared with other surgical controls; and to establish whether preoperative screening of haemoglobin level is warranted in such patients. Children aged 1-10 years admitted electively for ENT surgery or for general surgical procedures had blood taken for haemoglobin level, mean cell volume and serum ferritin. Their age, weight, socioeconomic class and ethnic background were recorded. A total of 100 patients entered the study, in a six-month period. The mean ages and weights for the two groups were statistically different, so allowance was made for this in calculations. Social class was not significantly different. No relationship could be established between haemoglobin level and ferritin level for individual patients. Multiple regression analysis for haemoglobin level, mean cell volume and for ferritin level showed that allowing for the age and weight differences these variables were not significantly different for the two groups. This study has therefore shown no increased incidence of iron deficiency in paediatric ENT inpatients. Each Department should formulate its own policy on pre-operative haemoglobin screening, based on local considerations.

A group of 54 patients with previously untreated ENT malignancies were studied and findings regarding five markers generally associated with cancers (CEA, SCC, TPA, CA 50 and ferritin) are presented. The specificity of these markers always proved to be greater than 95% while their sensitivity ranged from 13% to 43%, reaching 72% as a combination of all five markers. The results obtained during follow-up on 21 randomized patients was not satisfactory due to poor sensitivity. In the opinion of the authors, the five markers assayed appear to have no distinct function in monitoring ENT cancers. The sole exception to this is SCC which presents a moderate correlation (60%) with tumor growth.

Eighty eight (88) beta-thalassemic patients undergoing regular transfusion- chelation therapy with desferrioxamine (DFO) were studied for ENT problems from 1988 to 1993, as DFO has been implicated for auditory neurotoxicity. The mean age of the patients was 9.66 +/- 3.1 years, their pre-transfusion haemoglobin level was 9 +/- 2 g/dl, serum ferritin level was 2065 +/- 898 ng/ml and the daily DFO dose was 50.7 +/- 9.5 mg/kg for 5 days/week. The ENT study included, ENT examination, pure tone audiometry, speech audiometry, tympanometry, tone decay test and ABR. During this 6-year study 24/88 (27%) patients developed bilateral or ipsilateral sensorineural hearing loss in high tone frequencies, sometimes exceeding 80 dB, which was attributed to DFO toxicity. Therefore, a reduction or temporary withdrawal of DFO followed. After this intervention 12/24 patients recovered almost completely, 7/24 remained stable and 5/24 presented aggravation of their hearing loss. This study confirms the DFO induced auditory neurotoxicity and the necessity of periodical audiology control of beta-thalassemic patients for prompt diagnosis and management of this complication.
