- One hundred and thirty-two consecutive soccer players (117 males and 15 females, median age 23, range 16-39 years) underwent primary reconstruction of the anterior cruciate ligament (ACL) with an iliotibial band (ITB) autograft. AU patients were followed prospectively for a minimum of 2 years. One hundred and eighteen patients (89%) attended an independent observer follow-up after a median of 47 (24-92) months. The time before participating in soccer was a median of 7 (5-24) months. At a median of 4 years, 80 (68%) mere still active soccer players, while 38 had changed activity to a lower level. Twenty-five gave up soccer playing for reasons unrelated to the knee, and 13 (11%) gave up due to problems from the reconstructed knee. The Lysholm score improved from a median of 82 (range 42-99, mean [SD] 80.5 [+/-11.9]) points prior to the operation to a median of 99 (range 57-100, mean [SD] 94.6 [+/-8.5]) at followup. The Tegner score improved from a median of 3.5 (0-7) preoperatively to 9 (1-10), Four patients (3%) sustained a rupture of the graft: three ruptures occurred among the 15 females (20%), and one was seen among the 117 males (0.8%) (P=0.01). Eight per cent had predominantly minor cosmetic complaints from the donor-site hernia, while 51% had temporary discomfort from the staples used for graft fixation. Using the ITB autograft for ACL reconstruction, we found excellent and good results in soccer players with ACL deficiency and high demands for optimal knee function. The failure rate in general was comparable with other methods, and the majority was still active in soccer sports at a median of 4 years after surgery, An unacceptably high rerupture rate was registered in female players.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: In a nurse's future practical work, which is rapidly developing and changing, ethics will play an important role. A nurse student needs her/his own experience from patient care as well as training in reflecting upon ethical matters to manage future work situations. The aim of the study behind this article was to find the ethical problems that engage students, how they can correlate theoretical knowledge with practical experience and what insights in ethics they may achieve by reflecting on the experiences.Method: The study entailed examining written assignments, submitted by the students during their clinical education in medicine and surgery. Data consisted of 46 students' reports describing practical patient care situations on which the students had made reflections from an ethical point of view.Results: The most common ethical problem described by the students was the violation of the integrity of either a patient or his relative as well as disrespect of their autonomy. The actions taken by the students in these situations most often followed two lines: either taking a clear active part for the patient, or playing a passive role, not taking the action considered to be appropriate. Their passivity was due to fear of not being accepted by the staff. The insight and understanding gained by the students from these ethical dilemmas were: to act differently in a similar situation in the future, to be confident, and to listen to the patient in order to understand his/her needs. The students clearly showed their ability to correlate theoretical knowledge with practical experience the dynamics of their reasoning.Conclusion: The study indicated that reflections made by students can lead to an increased awareness of the need for knowledge about nursing, about own actions and behaviour, and the feelings and values that influence actions. It seems possible that the ethical competence gained by the students reflecting on situations with moral dilemmas, could be improved, if they were helped to develop and absorb certain virtues or abilities. In the students' reflections some qualities emerged as important, e.g. courage, sensitivity, judgement, and ability to perform a dialogue.

Modification of IgE Binding during Heat Processing of the Cow's Milk Allergen ?-Lactoglobulin

- The effect of heat treatment on the IgE binding ability of ?-lactoglobulin, as pure protein or in whole milk, was studied by inhibition of IgE antibody binding using FEIA-CAP inhibition. A slight but significant decreased IgE binding was seen between unheated and heat-treated ?-lactoglobulin solution at 74 °C (IC50 = 2.03 and 3.59 ?g/mL, respectively, p = 0.032). A more pronounced decrease was found at 90 °C with an IC50 of 8.45 ?g/mL (p = 0.014). The inhibition of IgE binding of milk after heat treatment at 90 °C was also significantly decreased (p = 0.007). However, at all heat treatments, a similar total amount of IgE antibodies could be inhibited at a sufficiently high concentration of ?-lactoglobulin. The inhibiting ability of ?-lactoglobulin was significantly impaired in some fermented acidified milk products such as yogurt as compared to that in nonfermented milk (p < 0.001). There was only a small difference of IgE binding between the native forms of genetic variants A and B.

Tidskriftsartikel (refereegranskat)abstract
- We performed combined internal and external anterior cruciate ligament (ACL) reconstruction with the iliotibial band autograft in 169 consecutive patients with chronic ACL insufficiency who were followed up for 24-61 months. Of these, 155 (91%) agreed to an additional independent observer follow-up after 24-92 months. Eight patients (5%) had sustained a rerupture/elongation of the graft and were operated on again, nine (6%) had sustained a tear of the contralateral ACL. Knee function and activity increased after the reconstruction. Lysholm scores improved from median 81 preoperatively to 99 at follow-up and Tegner scores from median 4 to 7. At follow-up 97 (71%) were active at the same level as prior to injury. In 17 of the 40 patients (12%) dropping to a lower activity level this was due to knee problems. The side-to-side difference in anterior-posterior knee laxity was more than 3 mm in 18 knees (13%) and more than 5 mm in 3 knees (2%). Including eight reruptures, this results in a "stability" failure rate of 8.8%. The overall IKCD rating showed normal knee function in 88 (73%) and nearly normal knee function in 30 (25%). Anterior knee pain was present in 14 (10%) of the patients at follow-up. Patients with isolated ACL injury had higher Lysholm scores and Tegner scores than patients with associated injuries. No clinical signs of varus knee development were seen. Of the 155 patients 94% would have the procedure repeated if necessary with the knowledge that they have today. The combined internal and external iliotibial band procedure can restore knee stability and function in the majority of chronic ACL-insufficient knees.
