    Notes: Abstract Periodontal conditions among an adult population of 161 dentate patients with rheumatoid arthritis (RA) were compared with those of an age and sex-matched random sample of non-rheumatic subjects. The number of teeth and prevalence of dental plaque, calculus, gingivitis, and deepened periodontal pockets were recorded. Alveolar bone breakdown and the distribution of subjects according to severity of periodontal disease were also registered. There was a tendency towards better periodontal conditions among RA-patients, severe periodontal breakdown occurring less frequently among RA-patients (12%) than among the controls (16%). The RA-patients had less plaque and calculus than the control group, a finding which could indicate a difference in periodontal care

    Notes: Abstract The oral status of an adult population of 204 patients with rheumatoid arthritis (RA) was compared with that of an age and sex-matched random sample of non-rheumatic subjects. The percentage of edentulous subjects, number of existing teeth in dentate subjects, prevalence, and quality of fixed and removable prostheses and prevalence of disorders of the stomatognathic system was recorded. The percentage of edentulousness among RA-patients was 17% and among non-RA subjects 19%. Number of remaining teeth was equal. 75% of removable partial and 62% of complete dentures among RA-patients were considered unsatisfactory compared to 25% and 56% respectively among non-RA subjects. Disorders related to the TMJ occurred much more frequently among RA-patients than among non-RA subjects. It is suggested that thorough stomatognathic examination and TMJ-prophylaxis be included in the overall care of RA-patients

    Notes: Abstract: Bone mineral area (BA), total bone mineral content (TBMC) and total bone mineral density (TBMD) were assessed by dual-energy X-ray absorptiometry (DXA) in 396 randomly selected, healthy 15-year-old Swedish boys and girls. The influence of body size, pubertal development, physical activity level (PAL), total energy expenditure (TEE), dietary intake of energy, calcium and vitamin D, and alcohol and smoking habits on TBMC and TBMD were examined in bi- and multivariate analyses. In bivariate analyses BA, TBMC and TBMD showed strong correlations with weight, height and TEE in both sexes. In boys but not in girls these bone variables were significantly correlated with dietary intakes of energy, calcium and vitamin D. No significant correlations were found between PAL and the three bone variables. In multivariate analyses with TBMC as dependent variable BA, height, weight and Tanner stages explained 88% and 87% of the variance in boys and girls respectively. In similar analyses with TBMD as dependent variable the corresponding figures were 50% and 54%. The major part of the variance in all these models was explained by BA, and only a few percent by all the other independent variables. No significant reduction was found when TEE or daily intakes of calcium or vitamin D were introduced into the models. These results illustrate the importance of including BA, weight and height as independent variables in regression models of TBMC to avoid spurious associations with other variables in the analyses. The results may also indicate that in normal Swedish adolescents environmental factors such as dietary intake of nutrients play a minor role as determinants of bone mineralization. High levels of physical activity and bone mineral measures possibly explain the lack of significant correlations between these variables and do not imply a lack of association.

    Notes: Summary It is well recognised that the newborn of diabetic mothers may be overweight and obese, presumably due to excessive glucose and insulin levels in the fetus. Since recent evidence indicates that the number of fat cells is established early in life, we studied the effect of intrauterine hyperglycaemia and hyperinsulinaemia on adipose tissue cellularity. Six men (age range 21–26 years) and six women (age range 18–24 years) were investigated. Their weights at birth generally exceeded the average value by 2 S.D. As a group they were not obese at the time of the investigation and neither total number of fat cells, average cell size nor body fat differed significantly from controls of the same age. There was no correlation between the number of fat cells and the weight at birth. The adipose tissue cellularity in the offspring of alloxan-diabetic rats (AX) and in controls (C) of equal weight was also studied. When sacrificed (after 40 days) body weights and the weights of the epididymal and retroperitoneal fat pads were similar in the AX and C groups. However, the number of fat cells of the retroperitoneal fat pad was significantly increased in the AX group, while the cell size was slightly diminished. Cell data of the epididymal fat pads were not significantly different. The results indicate that excessive glucose and insulin levels in utero may influence the number of fat cells, but, in man, they do not seem to lead to a permanent hyperplasia of the adipose tissue.

    Notes: Summary Fifty-one consecutive patients with metastatic lesions of the cervical spine were treated surgically. The most common primary tumor types were breast cancer and myeloma. In 14 (27%) patients, the cervical lesion was the first manifestation of the malignancy. All patients suffered from severe pain but only six had long tract symptoms. Five tetraparetic patients were confined to bed. Vertebral body collapse occurred in 73% of cases. The surgical technique was individualized according to the patient's general condition, the site of metastasis on the vertebra, and the level and number of levels bearing in mind that the treatment is palliative in nature. The goal of treatment was a better quality of life. In the upper cervical spine the technique described by Sjöström et al. was used, if technically possible. If the odontoid process had been totally destroyed, an occipitocervical stabilization was chosen. In the lower cervical spine, an anterior approach was used to resect the tumor growth. Anterior support was provided with bone cement if the patient was not expected to survive long; otherwise bone grafting was used. In cases with two or more levels of involvement, a combined anteroposterior stabilization was usually performed. Good pain relief was achieved postoperatively. The operation was generally well-tolerated by the patients, mild dysphagia being the most common complaint. One patient died 2 days postoperatively of heart failure, giving a post-operative mortality of 2%. Rhizopathy symptoms were relieved totally in 15 patients and partially in 6. Five of six tetraparetic patients could walk postoperatively. Mechanical failures occurred three times, due to local progress of the metastatic lesion, which led to reoperation on two occasions. The average postoperative survival was 12 months. Patients with metastases from breast cancer or myeloma had the longest survival. Our study suggests that stabilization is important in the cervical spine when metastatic lesions jeopardize stability. Stabilization is effective in relieving pain and preventing paraplegia.

    Notes: Summary Spinal canal areas were measured prospectively in 22 consecutive burst fractures of the thoracolumbar junction, preoperatively, within 1 week postoperatively and 1 year after operation. Preoperative canal encroachment averaged 38% (range 10%–70%) of the estimated original area. The 11 patients with neurological impairment had a significantly more severe initial canal encroachment (mean 48%) than those who were neurologically intact (mean 33%). Postoperatively, canal encroachment had decreased to a mean of 18% (range 0%–62%). Within 12 to 15 months postoperatively, canal encroachment was further reduced by resorption of bone fragments to a mean of 2%. The largest observed remaining encroachment was 29%. The amount of bone resorption correlated significantly with the persistent postoperative encroachment. A critical appraisal of the methods used to assess the pre-fracture canal area revealed that reconstructing the vertebral foramen of the fractured vertebra on CT scans substantially overrated the original area as compared with averaging the canal area of the two adjacent vertebrae.

    Notes: Summary The efficacy of ‘limited posterior surgery’ for metastases in the thoracic and lumbar spine was studied prospectively in 51 patients (32 men and 19 women, mean age 64 years). The most common primary tumors were prostate, breast, and renal carcinoma, 37 patients had metastases in the thoracic spine and 14 in the lumbar spine. Indications for surgery were severe pain or neurologic deficit. Of the 46 patients with neurologic symptoms, 25 were unable to walk. Surgery was confined to direct or indirect decompression and stabilization with a pedicle screw fixator over few segments as possible. Pain, as well as a variety of functional performance parameters and residential status were registered preoperatively and after surgery at 3, 6, 9, and 12 months, and at 6-monthly intervals thereafter. Pain was rated by the patient on a Visual Analog Scale, and functional performance was assessed with the Eastern Co-operative Oncology Group (ECOG) Performance Status Scale. We had no perioperative neurologic deterioration or death. Nineteen of the 25 nonambulatory patients regained their walking ability. Postoperative pain relief was significant and lasting over time. Nearly half of the patients attained improvement in functional performance. The median survival was 8 months. Older age and intact postoperative walking ability were positive factors for survival.
