A survey among Danish students revealed that 33 (7.2%) of the respondents had experience with hallucinogenic mushrooms (HM). Afterwards these students answered an extended questionnaire about habits and pattern of consumption. It seems that mushroom use is experimental and may be due to risk-seeking behaviour but is mostly recreational and restricted to a few events. Age over 25 years and male sex were statistically related to a higher lifetime consumption rate of HM. The age of first time users was significantly lower for marijuana than for HM. Only 15 of the respondents wanted to continue use. Most of them were males and they had significantly more friends with HM experience than those who would not continue. We recommend that surveys of drug abuse include questions concerning HM to monitor the trends and extent of HM abuse.
The aim of this questionnaire survey was to investigate the extent of hallucinogenic mushroom consumption among students from a high school in the county of Aarhus, Denmark and among students at the University of Aarhus and students from the Danish school of journalism in Aarhus, Denmark. 3% of the high school students had used psilocybine-containing mushrooms as a hallucinogen. Only 1% had experience with LSD. Of the students at the University of Aarhus, and students from the Danish school of journalism in Aarhus, 333 persons (83%) returned the anonymous questionnaire. 9% had experience with hallucinogenic psilocybine containing mushrooms while only 2% had LSD experience. The use of hallucinogenic mushrooms was surprisingly high. This suggest that mushrooms are the most commonly used hallucinogenic substance in Denmark and that the use has exceeded that of LSD. Compared to non-users mushrooms users had significant more friends with mushroom experience. Furthermore, the study shows that the intention to use mushroom is commoner in persons who have friends with HPS experience. We find that the use of mushroom takes place in minor groups known to each other. Compared to non-users, mushroom-users are significant more experienced with marijuana and other substances. Unfortunately, our data do not permit us to show whether mushroom users are more inclined to try other drugs or whether persons with a high drug experience use mushrooms as well. Further investigation on the subject is recommended.

With the object of investigating the occurrence of pain and dysaesthesiae in the scar following mastectomy, 120 were interviewed by a standard questionnaire in a prospective study. These women had commenced postoperative control or treatment in the Department of Oncology in the University Hospital of Aarhus consecutively during a one-year period. One hundred and ten of these women were interviewed again one year later. In 92% of the patients with scar pain and dysaesthesiae, these appeared within the first three months postoperatively. At the first interview, 42 patients (35%) had scar pain and 15 of these (13%) experienced constant scar pain. One year later, 25 patients (23%) still had scar pain and 13 patients (12%) had experienced persistent scar pain throughout the entire year. Two of the patients (8%) with scar pain had constant pain while, at the second interview, 14 patients (56%) reported that the scar pain lasted for seconds. Twenty-seven patients (23%) had dysaesthesiae at the first interview while 29 patients experienced these continually one year after operation. Both the intensity and the duration of the scar pain diminished with the elapse of time. This held also true where dysaesthesiae were concerned but was not so marked.

Intraocular pressure (IOP) was measured before and 6, 24, 48 and 72 h after extracapsular cataract extraction with implantation of a posterior chambers lens in 3 groups of patients. Group I (30 patients): Sodium hyaluronate (Healon) was used during anterior capsulotomy and lens implantation and was aspirated at the end of surgery. Group II (22 patients): Healon as in group I + 500 mg acetazolamide at the end of surgery. Group III (17 patients): BSS and/or air was used instead of Healon during surgery. In all groups statistically significant rises in IOP after 6 h were followed by significant falls in the remaining post-operative period. The rise and subsequent fall in IOP was significantly greater in group I than in group III. Acetazolamide in group II did not prevent excessive rises in IOP. Aspiration probably shortens the period of Healon-induced hypertension. We recommend a meticulous aspiration of Healon at the end of surgery.
