- Serum levels of squamous cell carcinoma antigen, carcinoembryonic antigen, CA 125, tissue polypeptide antigen, CRP, alpha 1-antitrypsin and haptoglobin were determined peri- and postoperatively in patients undergoing surgery for benign gynecological disease (n = 18) and postoperatively in women operated for cervical carcinoma (n = 23). The only significant changes seen after premedication, during anesthesia and during surgery were a decrease in serum concentrations of alpha 1-antitrypsin and haptoglobin. We found no postoperative changes in the serum levels of squamous cell carcinoma antigen nor in carcinoembryonic antigen values. However, the latter analyte was influenced by smoking habits. Elevated levels of CA 125 and tissue polypeptide antigen were found in the cancer patients, predominantly within the first 1-3 weeks after surgery. These levels decreased to normal values within 4-6 weeks postoperatively. The median intraindividual coefficients of variation for the tumor markers ranged between 15% and 28% in 30 control women not having surgery. In general, it would seem advisable to wait 6 weeks after surgery before monitoring with CA 125 and TPA is started.

Influences of diet and surgical trauma on serum alkaline DNase activity levels.

- Changes in serum alkaline DNase activities might predict the therapeutic response in various malignant diseases. A decrease in serum alkaline DNase activity within days from the onset of therapy has been related to tumour necrosis and may be a possible sign of clinical response to effective treatment. To study if changes in serum alkaline DNase activity could be induced by non-tumour related tissue destruction, sera were collected on several occasions perioperatively in 18 patients undergoing surgery for benign gynaecological disease. Thirty apparently healthy women served as the control group. A significant decrease (P less than 0.001) in serum alkaline DNase activity was observed after an overnight fast in both groups of women. In contrast to the control women, the operated patients showed a significant decrease (P less than 0.001) in serum alkaline DNase activity throughout the operative period and 1 week postoperatively. We conclude that serum alkaline DNase activity is influenced by dietary factors as well as surgical trauma. These factors may limit the clinical usefulness of SADA in patients with cancer.

- Serum levels of squamous cell carcinoma antigen SCC, carcinoembryonic antigen CA 125, and tissue polypeptide antigen were determined in 142 patients with primary cervical carcinoma, 60 patients with precancerous lesions and in 129 healthy women. With regard to elevated tumour marker levels, specificity ranged from 94.6% to 97.7%. Sensitivity was highest (44.4%) for SCC. A stage relation was found for all tumour markers except for carcinoembryonic antigen. In stage Ib, SCC levels increased according to tumour volume. SCC, CA 125 or both markers were elevated in 7 of 8 patients with pelvic lymph node metastases compared with only 17 of 58 patients with negative nodes (P = 0.005). In a multivariate analysis, pretreatment serum levels of SCC and CA 125 were found to be significantly related to patient survival, in addition to stage. In cervical SCC, the risk of a fatal outcome increased 16 times with SCC levels > or = 4.5 ng/ml, compared with SCC levels < or = 1.3 ng/ml. We conclude that pretreatment serum levels of SCC may be of value as an adjunct to clinical staging. In addition, serum determinations of SCC and CA 125 seem to be useful in predicting the risk of pelvic lymph node metastases and as prognostic risk factors for disease outcome.

Imitation in Autism: A preliminary research note

Tidskriftsartikel (refereegranskat)abstract
- Previous studies have claimed that children with autism are poor imitators and a lack of imitative capacity has been included by some investigators as one early sign of autism. Presented here are results from a pilot study focusing on observed imitation after presenting 15 tasks to five children with autism (mental age 25-51 months). Imitation tasks involving simple object manipulation, vocal responses, facial and manual gestures, and object substitution were presented to each child. The performance of the children with autism is compared with (1) three normaI4-year-old children (for all 15 tasks), and (2) observations from 28 healthy l-year-olds (for 10 of the tasks used). The findings indicate that the autistic group displayed the highest level of imitation on object manipulation and vocal tasks while object substitution, facial, and motor imitation acts seemed to be difficult for children with autism. However, the small number of children included as well as the individual variation observed among the autistic subjects precludes any definite conclusions from these pilot observations. It is hypothesized that imitation in children with autism has to be studied separately for different domains and probably also for different subgroups within autistic population.

Visual field defect during low-dose methotrexate therapy
- 1992

- A patient was treated with low-dose methotrexate because of psoriasis that did not respond to conventional therapy. During treatment, visual symptoms occurred; optic disc swelling was found, and later slight optic disc atrophy. Moreover, paracentral relative visual field defects showed fluctuations parallel to methotrexate dose changes. It seems likely that methotrexate affected optic nerve function.
