Four patients are described who presented with congenital finger contractures and arthropathy. There was synovial cell hyperplasia and giant cells but no inflammatory process. Radiographs showed flattening of the metacarpal and metatarsal heads and the proximal femoral ossification centres. In the oldest patient the process had subsided leaving slight contractures but severe impairment of hip mobility. In another the arthropathy was still prominent in the early teens. In a third, finger contractures had failed to respond to conservative or surgical measures. [ABSTRACT FROM PUBLISHER]

Basal and maximum acid outputs were measured on two occasions in a group of 15 duodenal ulcer (DU) patients in remission. The initial study was carried out after a nocturnal acid collection, whereas the second was carried out in the conventional manner without preceding nocturnal aspiration. No difference in the basal acid output, concentration, or volume of secretion was found between the two study days. Maximum acid output on the other hand, was significantly (p < 0.02) reduced from 30.9 (14.2-41.2) mmol/h, median (+range), to 23.7 (8.1-33.7) mmol/h after overnight aspiration. The reduction in maximum acid output was attributable to a fall in the volume of gastric secretion from 280 (170-371) ml to 230 (142-280) ml. No fall in acid concentration was seen. We conclude that overnight gastric aspiration does not affect basal gastric secretion, but reduces the maximum acid output as a result of a reduced secretory volume. [ABSTRACT FROM AUTHOR]

Mothers with eating disorders can face additional challenges with infant feeding, and there is evidence they are likely to cease breastfeeding earlier than intended. However, there is little research exploring this. The present study used interpretative phenomenological analysis to explore the lived experience of infant feeding for mothers suffering from or recovering from an eating disorder. Semistructured interviews were conducted with six women-five who had breastfed and one who formula-fed. The women experienced two incompatible worlds-motherhood and an eating disorder. Tensions were sometimes resolved by reducing eating disordered behaviour alongside immersion in motherhood. Two participants did not find infant feeding particularly important for their journey into motherhood. Four recounted a positive shift in their relationship to their body through breastfeeding and felt their embodied experience of mothering provided a route out of eating disordered behaviour. However, doubts about their mothering and infant feeding capabilities could be amplified by feeling mistrusted by others and by the relative silence around eating disorders within maternity care services. Respectful dialogue with health care professionals was particularly valued where this occurred. Although long-term outcomes for the participants are unknown, the study suggests women with a history of eating disorders can form successful breastfeeding relationships and may be motivated to engage in collaborative risk assessment. However, they need support in managing emotional challenges. Training around eating disorders for maternity care professionals is likely to be useful for enhancing confidence in engaging mothers proactively to share concerns about eating, weight and body shape., (© 2024 The Author(s).

Providing care and education for a patient on peritoneal dialysis (PD) requires that the nephrology nurse have knowledge and expertise in the PD access. This article provides information on types and placement of PD catheters, pre-placement and post-placement education and care, how to assess PD catheter exit site healing, and initial use of the PD catheter for access., Competing Interests: The author reported no actual or potential conflict of interest in relation to this continuing nursing education activity., (Copyright© by the American Nephrology Nurses Association.)

Background: Although informal end-of-life care is associated with significant physical and psychological morbidity for caregivers, few interventions have been developed to meet these needs. This study aimed to identify existing coping and support mechanisms among informal cancer caregivers in order to inform intervention development., Method: One-to-one semi-structured qualitative interviews were undertaken with 20 informal cancer caregivers of home palliative care patients., Results: Caregivers' existing coping strategies included distraction, mental stimulation, emotional release, looking for the positive aspects of caregiving, and disengaging from stressful thoughts. The majority of the participants described the importance of support and understanding form family and friends., Conclusions: The data suggests that feasible and acceptable interventions will be those that are targeted to caregivers to assist them in optimising existing coping strategies and support from family and friends.

Heritable predisposition to inflammatory bowel disease (IBD) has been demonstrated by epidemiological and genetic analysis. Linkage of IBD to broad regions of chromosome 16 has been established by analysis of multiple populations. NOD2, located on proximal 16q, was recently identified as an IBD gene. As the linkage regions on chromosome 16 are large, we have investigated the possibility that NOD2 is not the only IBD gene located on this chromosome. A high-density experiment using 39 microsatellite markers was performed to identify additional regions of association, and to indicate areas of interest for further investigation. A triple-peaked configuration of the linkage curve with peak logarithm of odds (lod) scores of 2.7, 3.2, and 3.1 was observed on proximal 16p, proximal 16q, and central 16q, respectively. The cohort was stratified by coding individuals carrying the NOD2 single nucleotide polymorphism (SNP)8 and SNP13 "unknown." Significance at the central peak, corresponding to the genomic location of NOD2, then decreased from 3.2 to 1.2. The maximal lod scores on the proximal p-arm (lod = 2.1) and central q-arm (lod = 2.6) changed only moderately. An exploratory association analysis (TRANSMIT) yielded a strong lead at D16S3068 (P = 0.00028). The region around this marker was further investigated by using anonymous SNPs. An associated haplotype containing three SNPs was identified (peak significance P = 0.00027, IBD phenotype). On stratification based on NOD2 genotype, this significance increased to P = 0.0001. These results confirm the importance of NOD2 and provide evidence for a second IBD gene located on chromosome 16p.

Background Genetic predisposition to inflammatory bowel disease (IBD) has been shown by epidemiological and linkage studies. Genetic linkage of IBD to chromosome 16 has been previously observed and replicated in independent populations. The recently identified NOD2 gene is a good positional and functional candidate gene since it is located in the region of linkage on chromosome 16q12, and activates nuclear factor (NF) kappaB in response to bacterial lipopolysaccharides. Methods We sequenced the coding region of the NOD2 gene and genotyped an insertion polymorphism affecting the leucine-rich region of the protein product in 512 individuals with IBD from 309 German or British families, 369 German trios (ie, German patients with sporadic IBD and their unaffected parents), and 272 normal controls. We then tested for association with Crohn's disease and ulcerative colitis. Findings Family-based association analyses were consistently positive in 95 British and 99 German affected sibling pairs with Crohn's disease (combined p<0.0001); the association was confirmed in the 304 German trios with Crohn's disease. No association was seen in the 115 sibling pairs and 65 trios with ulcerative colitis. The genotype-specific disease risks conferred by heterozygous and homozygous mutant genotypes were 2.6 (95% CI 1.5-4.5) and 42.1 (4.3-infinity), respectively. Interpretation The insertion mutation in the NOD2 gene confers a substantially increased susceptibility to Crohn's disease but not to ulcerative colitis.
