The use of local anaesthesia for middle ear surgery is long established and has many advantages. However, it is only performed by a small number of UK otolaryngologists (20%). This lack of enthusiasm is due to concerns that patients may not tolerate the discomfort during the operation. Therefore, a survey was conducted on patients who had middle ear operations: stapedotomy, myringoplasty, ossiculoplasty and mastoidectomy. The intense sensation of noise during the operation (29.6% of patients) and anxiety (24%) were the most common discomforts, followed by dizziness (14.8%), backache (13.9%), claustrophobia (9.3%) and earache (1.9%). In spite of these discomforts, 89% of patients still preferred local anaesthesia to general anaesthesia for a similar procedure. The author suggests that good patient selection, pre-operative explanation and the use of appropriate sedation are the important factors for local anaesthesia ear procedures to be acceptable to patients.

Simulated 4-h flights were carried out in a realistic model of a three-row, 21-seat section of an aircraft cabin that was reconstructed inside a climate chamber. Twenty-nine female subjects, age 19-27 years, were split into two groups; each group was exposed to four conditions: two levels of ozone (<2 and 60-80 p.p.b.) at two outside air supply rates (2.4 and 4.7 l/s per person). A companion study measured the chemicals present in the cabin air during each of the simulated flights. The subjects completed questionnaires to provide subjective assessments of air quality and symptoms typical of complaints experienced during actual flight. Additionally, the subjects' visual acuity, nasal peak flow and skin dryness were measured. Based on self-recorded responses after 3(1/4) h in the simulated aircraft cabin, they judged the air quality and 12 of the symptoms (including eye and nasal irritation, lip and skin dryness, headache, dizziness, mental tension, claustrophobia) to be significantly worse (P<0.05) for the "ozone" condition compared to the "no ozone" condition. The results indicate that ozone and products of ozone-initiated chemistry are contributing to such complaints, and imply previously unappreciated benefits when ozone is removed from the ventilation air supplied to an aircraft cabin.

Alopecia is a very common side effect of cytostatic therapy and is considered one of the most emotionally distressing effects. To prevent alopecia scalp cooling is currently used in some indications in medical oncology in 59 hospitals in the Netherlands. The success of scalp cooling depends on various factors such as type of chemotherapy, dose, infusion time, number of treatment cycles and combinations of drugs. In general, scalp cooling is well tolerated. The reported side-effects are headache, coldness, dizziness and sometimes claustrophobia. An increase in the risk of scalp metastases has not been demonstrated. Proceeding from the South Netherlands Comprehensive Cancer Centre a national working group is put together in order to draw up a national guideline for chemotherapy-induced alopecia.
