Abstract
Background Children and adolescents with juvenile idiopathic arthritis (JIA) may suffer pain from temporomandibular disorder (TMD). Still, routines for the assessment of temporomandibular joint (TMJ) pain in health and dental care are lacking. The aims of this study were to examine the prevalence of TMD in children and adolescents with JIA compared to their healthy peers and to investigate potential associations between JIA and TMD. Methods This comparative cross-sectional study is part of a longitudinal multicentre study performed during 2015–2020, including 228 children and adolescents aged 4–16 years with a diagnosis of JIA according to the ILAR criteria. This particular substudy draws on a subset of data from the first study visit, including assessments of TMD as part of a broader oral health examination. Children and adolescents with JIA were matched with healthy controls according to gender, age, and centre site. Five calibrated examiners performed the clinical oral examinations according to a standardised protocol, including shortened versions of the diagnostic criteria for TMD (DC/TMD) and the TMJaw Recommendations for Clinical TMJ Assessment in Patients Diagnosed with JIA. Symptoms were recorded and followed by a clinical examination assessing the masticatory muscles and TMJs. Results In our cohort of 221 participants with JIA and 221 healthy controls, 88 (39.8%) participants with JIA and 25 (11.3%) healthy controls presented with TMD based on symptoms and clinical signs. Painful TMD during the last 30 days was reported in 59 (26.7%) participants with JIA vs. 10 (5.0%) of the healthy controls (p < 0.001). Vertical unassisted jaw movement was lower in participants with JIA than in controls, with means of 46.2 mm vs. 49.0 mm, respectively (p < 0.001). Among participants with JIA, a higher proportion of those using synthetic disease-modifying antirheumatic-drugs and biologic disease-modifying antirheumatic-drugs presented with painful masticatory muscles and TMJs at palpation. Conclusion Symptoms and clinical signs of TMD were seen in approximately half of the JIA patients compared to about one fourth of their healthy peers. Painful palpation to masticatory muscles and decreased vertical unassisted jaw movement were more frequent in participants with JIA than among healthy controls and should be part of both medical and dental routine examinations in patients with JIA.

Abstract
Intrauterine growth restriction (IUGR) followed by accelerated growth after birth is associated with an increased risk of abdominal (visceral) obesity and insulin resistance in adult life. The aim of the present study was to determine the impact of IUGR on mRNA expression and protein abundance of insulin signaling molecules in one of the major visceral fat depots, the omental adipose depot. IUGR was induced by placental restriction, and samples of omental adipose tissue were collected from IUGR (n = 9, 5 males, 4 females) and Control (n = 14, 8 males, 6 females) neonatal lambs at 21 days of age. The mRNA expression of the insulin signaling molecules, AMP-kinase (AMPK) and adipogenic/lipogenic genes was determined by qRT-PCR, and protein abundance by Western Blotting. AMPKα2 mRNA expression was increased in male IUGR lambs (0.015 ± 0.002 v. 0.0075 ± 0.0009, P < 0.001). The proportion of the AMPK pool that was phosphorylated (%P-AMPK) was lower in IUGR lambs compared with Controls independent of sex (39 ± 9% v. 100 ± 18%, P < 0.001). The mRNA expression and protein abundance of insulin signaling proteins and adipogenic/lipogenic genes was not different between groups. Thus, IUGR is associated with sex-specific alterations in the mRNA expression of AMPKα2 and a reduction in the percentage of the total AMPK pool that is phosphorylated in the omental adipose tissue of neonatal lambs, before the onset of visceral obesity. These molecular changes would be expected to promote lipid accumulation in the omental adipose depot and may therefore contribute to the onset of visceral adiposity in IUGR animals later in life.

Abstract
Last year, a course in clinical medical ethics for paediatricians had to be cancelled owing to lack of interest. To find the reason for this, and to learn what ethical problems the physicians encountered in the course of their work, how they solved them, and their attitude towards education in medical ethics, a questionnaire was sent to all members of The Norwegian Paediatric Association, to be answered anonymously. The most frequent excuses for not attending the course were pressure of work and lack of time. 37% claimed that they very often or often encountered ethical problems during their work. 20% often solved these problems alone, and two out of three after discussing them with colleagues. 51% felt a need to improve their competence to solve ethical problems. Only 16% reported having no such need. The authors discuss the form and content of the education in medical ethics.

Abstract
OBJECTIVE To investigate the occurrence and clinical correlation of the arg519-to-cys mutation in the type II procollagen gene in patients with osteoarthritis (OA). METHODS Sixty-six subjects from 7 families with a strong family history of generalized OA and 13 patients with erosive OA were evaluated clinically and radiologically. Blood samples from 58 subjects in the familial OA group and from all 13 patients with erosive OA were obtained for DNA analysis. Exon 31 of COL2A1, which spans residue 519, was amplified by polymerase chain reaction. RESULTS The arg519-to-cys mutation was detected in 2 of the 7 families with generalized OA. In these 2 families, the mutation was present in the 2 probands and in 19 other clinically affected family members, as well as in 3 (so-far) clinically unaffected family members (ages 25, 14, and 11 years). It was absent in 18 clinically unaffected members tested. The mutation was associated with a distinctive pattern of early-onset, aggressive, generalized OA with a mild spinal chondrodysplasia. Inheritance was autosomal dominant. No mutation was found in any of the patients with erosive OA. CONCLUSION The arg519-to-cys mutation defines a new pathogenic factor in generalized OA with characteristic clinical and radiologic features. The demonstration of a mutation in 3 of 8 families with OA studied thus far suggests a significant incidence of genetically related clinical OA.

Abstract
Clinical and mammographic data of 1009 consecutive patients were correlated with histopathologic data of 1144 biopsy specimens of nonpalpable breast lesions to better define the presentation and biologic behavior of early breast cancer. Patients with malignant neoplasms (269 [24%] of 1144 specimens) were older (mean age, 62.1 years) than patients with benign lesions (mean age, 54.9 years). Furthermore, patients with invasive disease were older (mean age, 63.3 years) than patients with noninvasive disease (mean age, 58.5 years) with an overall increased risk of invasive cancer per year of 1.035. A 58% incidence of invasive cancer was detected for lesions characterized by calcifications, while the incidence of invasive cancer was 84% for isolated mass lesions (relative risk, 4.31 for masses). Isolated mammographic calcifications associated with cancer appeared in a younger population and were significantly associated with noninvasive ductal cancer. Breast cancer presenting as a mammographic mass appeared in an older group and was highly associated with the presence of invasive disease.

Abstract
A total of 10,909 puerperal women from 6 different hospitals were screened for bacteriuria by culture of voided midstream urine (MSU), and a significant growth was found in 881 patients (8.1%). In 731 cases the urine was reexamined by using suprapubic aspiration (SPA), and in only 354 (48%) of the samples the diagnosis of bacteriuria was confirmed. The contamination rate of the MSU samples varied from 46 to 69% between the different hospitals, indicating that in the postpartum period positive MSU findings would necessitate more thorough examination in order to confirm the diagnosis of urinary tract infection. In our study, suprapubic aspiration was found to be a simple and acceptable method without any side effects. Confirmed bacteriuria occurred in 3.2% of the women. Operative delivery (Cesarean section, forceps and vacuum extractor delivery), epidural anesthesia and bladder catheterization increased the risk of bacteriuria in the postpartum period. Only 27% of the women with positive bladder urine complained of dysuria and this symptom was significantly more common in women who had been catheterized. 230 patients with confirmed bacteriuria with amoxycillin-sensitive bacterias participated in a randomized short-course treatment trial: 114 women received 3 days treatment with amoxycillin (1.5 g/day), 116 received the traditional 10 days therapy (750 mg amoxycillin/day). Both antibiotic regimens were observed to be effective with a cure rate of 96 and 98%, respectively. Short-course antibiotic treatment should thus be recommended to puerperal women with urinary tract infections since this avoids prolonged drug exposure to the lactating mother.

Abstract
A triphasic combined oral contraceptive containing fluctuating amounts of ethinylestradiol and levonorgestrel was tested clinically in a multicenter trial at six hospitals in Norway. 367 women were included in the study, 3 588 cycles were studied, and the follow up period was 12 months. The one year continuation rate was 67%. Five pregnancies occurred during the study period. All of them had to be considered as patient failures. The causes for stopping medication were side effects in about 50% and the rest for personal reasons. The cycle control taking into account duration of bleeding, amount of flow, and intermenstrual bleeding was good and comparable to the low-dose monophasic combined pills. The incidence of side effects was low. One woman had an increase in systolic blood pressure to more than 140 mmHg. Thrombophlebitis was not registered. In conclusion the triphasic oral contraceptive was effective and had a good cycle control and low incidence of side effects.

Abstract
Murine hybridoma antibodies to a human B-cell lymphoma were developed. After screening against normal T cells, monocytes, and granulocytes 11 antibodies that reacted with cells from other B-cell lymphomas remained, of which 10 showed individually distinct staining patterns, as tested by indirect fluorescence. When tested against lymphomas or cell lines, none of these antibodies revealed staining patterns suggesting reactivity with conventional B-cell surface markers, such as immunoglobulin, complement factor 3 receptors, or HLA-DR antigens. Only one of the antibodies (GB1) reacted with human serum, as determined by a blocking assay. The antibodies were found to belong to different immunoglobulin isotypes. Two antibodies (GB13 and GB14) reacted with greater than 5% of normal peripheral blood mononuclear cells. These reactions were mainly due to reactivity with B cells. The antibodies reacted only in a few cases with acute leukaemias, B-cell lines, and follicular lymphomas. On the other hand, distinct patterns of reactivity in different histological groups of diffuse lymphomas were obtained, suggesting that the antibodies may be useful in delineating phenotypic subsets among human B-cell lymphomas.

Abstract
Three males with the X-linked lymphoproliferative syndrome (XLP) with hypo- or agammaglobulinemia following Epstein-Barr virus (EBV) infection and two males with the chronic mononucleosis syndrome were investigated for immune responses to EBV-determined antigens. Males with XLP showed profound cellular immune defects. Markedly diminished responses of natural killer cell and interferon-activated killer cell activities and impaired leukocyte migration inhibition responses to phytohemagglutinin were determined in patients with XLP. The two patients with chronic mononucleosis showed less severe defects. All patients showed partial or complete impairment of their EBV-specific immune responses as measured by leukocyte migration inhibition. EBV-specific antibodies were markedly diminished against EBV-associated nuclear antigen, early antigen, and viral capsid antigen in males with XLP. In contrast, patients with chronic mononucleosis had elevated antibodies to most EBV-specific antigens. Individuals with life-threatening EBV-induced lymphoproliferative disorders may exhibit multiple defective immune mechanisms against the virus.

Abstract
We have already reported on a radioreceptor assay for catecholamines utilizing the microsome fraction of bovine myocardium as a catecholamine (CA) receptor and 3H-norepinephrine as a labelled CA. In order to increase the sensitivity of the radioreceptor assay, we used 4-(2-iodoethyl) pyrocatechol (125I-CA) as a ligand instead of 3H-norepinephrine and performed a radioreceptor assay for CA. The following results were obtained: 1) 125I-CA was able to bind alpha-receptors prepared from bovine myocardium. 2) The optimal amount of the microsomal fraction was 250 micrograms/tube, when 125I-CA of 50,000 c.p.m. was used. The appropriate conditions for incubation were 90 minutes at 20 degrees C in a pH 7.0 sucrose solution. 3) By this method utilizing 125I-CA, norepinephrine was detectable in a range from 500 pg to 10 ng/tube. 4) Various compounds with a catechol nucleus showed cross-reaction in this radioreceptor assay system. 5) Whereas beta-adrenergic blocking agents did not inhibit the binding of 125I-CA, phentolamine, a short acting type of alpha-adrenergic blocking agents, was effective in inhibiting the binding. However, dibenamine and phenoxybenzamine, long acting types of alpha-adrenergic blocking agents, increased the binding of 125I-CA to the microsomal fraction. 6) Utilizing this phenomenon, norepinephrine was detectable in the range from 100 pg to 5 ng/tube.
