Osteoarthritis: A Review of Novel Treatments and Drug Targets.

Osteoarthritis affects over 10% of our population over the age of 60 years old, significantly reducing their quality of life and increasing morbidity. A number of aetiological factors contribute to the development of osteoarthritis including obesity, genetic factors, injury and increasing age. Many of the pathological processes which underlie the condition remain poorly understood and therefore limited progress has been made in developing effective disease modifying treatments. This review article aims to summarise our current understanding of osteoarthritis, the molecular mechanisms which drive the disease and current progress in developing therapeutic strategies to target these.

Urinary symptoms in pregnant women in their third trimester-a cross-sectional study.

INTRODUCTION AND HYPOTHESIS: Urinary symptoms are common in pregnancy. Our study aims to understand the extent of these symptoms in a cohort of pregnant women in the third trimester and their impact on quality of life (QOL) from the women's perspective. METHODS: A single-centre cross-sectional study of self-reported urinary symptoms of pregnant women in the third trimester conducted from August 2018 at the Diana Princess of Wales Hospital, Northern Lincolnshire, and Goole NHS Foundation Trust, Grimsby, UK. We used an international validated questionnaire (ICIQ-FLUTS questionnaire) (Brookes et al. Am J Obstet Gynecol. 191(1):73-82, 2004). RESULTS: A total of 302 women were included in this study. Nocturia was the most common symptom, reported by 97%, affecting QOL in 80%. Urgency of micturition was the second most common, present in 83%, adversely affecting QOL in 75%. Our study showed a startling finding of bladder pain in 47% (95% CI 41.1%, 52.3%) of these women. There was a high prevalence of nocturnal enuresis in 9.9% (95% CI 7.05%, 13.8%). Straining during micturition is not a well-known symptom in pregnancy, however reported by 18.2% (95% CI 14.2%, 23.0%). CONCLUSION: The high prevalences of bladder pain, nocturnal enuresis and straining in the third trimester of pregnancy are novel findings. Our study also confirms that the prevalence of all voiding, filling and incontinence symptoms in pregnancy is significantly higher than in the non-pregnant population, having a negative impact on QOL, and yet is not discussed as part of routine antenatal care.

Supratentorial vs infratentorial posterior calvarial distraction osteogenesis for the increase of ICV in children with syndromic or multi-suture craniosynostosis: a retrospective cohort study.

PURPOSE: Craniosynostosis is the premature and pathological fusion of calvarial sutures. One modality of surgical treatment of syndromic craniosynostosis is posterior calvarial distraction (PCD). This can be either supratentorial or infratentorial. Currently, supratentorial PCD may be regarded as safer but produces a smaller increase in calvarial volume compared to infratentorial PCD. This study quantifies and compares the effectiveness of supratentorial and infratentorial PCD to help guide surgical decision-making. METHODS: The CT and/or MRI scans of 47 cases of craniosynostosis who underwent PCD from the Birmingham Children's Hospital (BCH) were converted to sagittal series multi-planar reformatted (MPR) scans for the manual calculation of ICV. The 47 cases were classified as having undergone either supratentorial or infratentorial PCD using lateral plain film radiographs, with 28 and 32 pairs of pre- and post-operative CT/MRI scans reviewed respectively. RESULTS: A statistically significant difference between supratentorial and infratentorial PCD was observed for the increase in supratentorial volume (STV) (P = 0.0458) and total intracranial volume (TICV) (P = 0.0437), but not for the increase in infratentorial volume (ITV) (P = 0.0697). The relationship for each volume trended towards convergence but was not achieved before the physical limit of 30 mm distraction had been reached. Intraclass correlation coefficient values for agreement of MRI and CT scans for STV, ITV and total ICV were 0.852, 0.864 and 0.854 respectively. CONCLUSION: Our evidence suggests that supratentorial PCD is more effective for increasing ICV in a clinical setting. CT and MRI imaging modalities are acceptably clinically interchangeable for calculating ICV in craniosynostosis.
