A Triad of Temporomandibular Joint Ankylosis, Mandibular Retrognathia and Severe Obstructive Sleep Apnoea: Case report
The surgical management of paediatric patients with temporomandibular joint (TMJ) ankylosis, mandibular retrognathia and obstructive sleep apnoea (OSA) is challenging. We report a nine-year-old boy who presented to the Department of Oral Health, Sultan Qaboos University Hospital, Muscat, Oman, in 2016 with complaints of limited mouth opening, loud snoring and excessive daytime sleepiness. He was diagnosed with TMJ ankylosis, mandibular retrognathia and severe OSA. The patient initially underwent mandibular distraction and, subsequently, release of the TMJ ankylosis and rib graft reconstruction. The overall patient outcome was successful, with improvement in OSA-related symptoms, good facial symmetry and adequate mouth opening.

Systemic Oxidative Stress Is Increased in Postmenopausal Women and Independently Associates with Homocysteine Levels
Oxidative stress plays a pivotal role in the pathogenesis of cardiovascular diseases (CVD). Postmenopausal women have an increased risk of developing CVD due to decreased estrogen availability, which is accompanied by increased oxidative stress. Serum free thiols (R-SH) provide a robust and powerful read-out of systemic oxidative stress. In this study, we aimed to establish serum levels of free thiols and explore associations between free thiols and demographic, clinical, and biochemical parameters related to obesity and the risk for developing CVD in both pre-and postmenopausal women. Serum free thiols were measured in a cohort consisting of healthy pre-(n = 223) and postmenopausal (n = 118) Omani women. Postmenopausal women had significantly lower levels of serum free thiols as compared to premenopausal women (762.9 Âą 85.3 vs. 780 Âą 80.9 ÂľM, age-adjusted p < 0.001). WomenⲠs age was positively associated with serum free thiol levels in premenopausal women (β = 0.36, p = 0.002), whereas an inverse association was observed in postmenopausal women (β = â0.29, p = 0.002). Homocysteine levels were significantly inversely associated with serum free thiol levels in both pre-(β = â0.19, p = 0.005) and postmenopausal (β = â0.20, p = 0.032) women, independent from known cardiovascular risk factors. In this study, we show that postmenopausal women are affected by increased systemic oxidative stress, which independently associates with homocysteine levels
The Learning Organisation and Health Care Education
The âLearning Organisationâ is a concept first described by Peter Senge as an organisation where people continuously learn and enhance their capabilities to create. It consists of five main disciplines: team learning, shared vision, mental models, personal mastery and systems thinking. These disciplines are dynamic and interact with each other. System thinking is the cornerstone of a true learning organisation and is described as the discipline used to implement the disciplines. In a learning organisation, health care education aims to educate its members with up to date knowledge to produce competent and safe personnel, who can promote quality in health care services. In addition, there are some educational concepts and theoretical models, which are of relevance to the learning organisation, and can provide a framework for managerial decisions. The stages required to achieve the principles of a learning organisation will be described in detail. Moreover, in a proper culture which supports the learning organisation, members continuously learn to improve the environment and never remain passive recipients
Genetic analysis and outcomes of Omani children with steroidâresistant nephrotic syndrome
Abstract Background Nephrotic syndrome (NS) is one of the most common kidney disorders seen by pediatric nephrologists and is defined by the presence of heavy proteinuria (>3.5âg/24âh), hypoalbuminemia (<3.5âg/dL), edema, and hyperlipidemia. Most children with NS are steroidâresponsive and have a good prognosis following treatment with prednisolone. However, 10%â20% of them have steroidâresistant nephrotic syndrome (SRNS) and fail to respond to treatment. A significant proportion of these children progress to kidney failure. Methods This retrospective study aimed to determine the underlying genetic causes of SRNS among Omani children below 13âyears old, over a 15âyear period and included 77 children from 50 different families. We used targeted Sanger sequencing combined with nextâgeneration sequencing approaches to perform molecular diagnostics. Results We found a high rate of underlying genetic causes of SRNS in 61 (79.2%) children with pathogenic variants in the associated genes. Most of these genetically solved SRNS patients were born to consanguineous parents and variants were in the homozygous state. Pathogenic variants in NPHS2 were the most common cause of SRNS in our study seen in 37 (48.05%) cases. Pathogenic variants in NPHS1 were also seen in 16 cases, especially in infants with congenital nephrotic syndrome (CNS). Other genetic causes identified included pathogenic variants in LAMB2, PLCE1, MYO1E, and NUP93. Conclusion NPHS2 and NPHS1 genetic variants were the most common inherited causes of SRNS in Omani children. However, patients with variants in several other SRNS causative genes were also identified. We recommend screening for all genes responsible for SRNS in all children who present with this phenotype, which will assist in clinical management decisions and genetic counseling for the affected families
