Mitochondrial myopathies are a spectrum of rare diseases caused by a genetic defect in ATP production at the level of the electron transport chain. The degree of disability is variable, but often patients are severely ill and highly susceptible to increased morbidity and mortality with infection. Covid-19 is known to be especially virulent in patients with significant comorbidities. In this case, a 27-year-old man with Myoclonus Epilepsy with Ragged Red Fibers (MERRF) presented in severe shock d...

Falls research among individuals with arthrogryposis multiplex congenita (AMC), a group of congenital conditions characterized by joint contractures in two or more body regions, is sparse. The primary objectives of this study were to estimate the prevalence of single, multiple, and injurious falls among adolescents and adults with AMC and identify factors associated with multiple and injurious falls. Individuals, aged 10-50 years, with a diagnosis of AMC completed questionnaires obtaining demogr...

Fibrodysplasia Ossificans Progressiva (FOP) is an extremely rare and disabling disorder that affects 1 in 2 million individuals worldwide. It is caused by mutations in bone morphogenetic protein which leads to extra-skeletal ossification of soft tissues in a characteristic cranio-caudal pattern. Hallux valgus, episodic flares and progressive functional disability are characteristic features. The cause of death is often cardio-respiratory failure following thoracic insufficiency. A two year 5-mon...

At least half of adults with intellectual disability are estimated to have diagnosed or undiagnosed chromosomal or DNA mutations as the cause of their intellectual disability, which, by definition, are rare. Mostly however, associated physical health problems are not rare. An unintended consequence of focus on the rareness of the cause of the intellectual disability, no matter how useful that is to understanding the syndrome, is that it deflects attention away from the relatively common physical...

Previous studies have demonstrated that CF prognosis is dependent of three major parameters: FEV1, BMI and need of intravenous antibiotic therapy. The CF centres of Frankfurt, Germany, and Moscow, Russia, care for cystic fibrosis patients. We decided to investigate and compare both centers from 1990 to 2015. No comparable study has been published so far. German patient data was collected from the national cystic fibrosis database “Muko.web”. Missing values were extracted from the Hospital In...

The human skeleton is composed of bone, a living tissue that undergoes constant development throughout life. It is well established that changes in bone metabolism during the developmental stages of growth, modelling and remodelling determine long-lasting physiological parameters, such as final height achieved, peak bone mass, bone quality and bone health. A complex interplay of environmental, genetic, nutritional, physiological and behavioural factors plays a role in these processes. These modi...

A 54-year-old male with a history of Maffucci syndrome and Marginal Zone Lymphoma, presented with a 4-week history of headache, right-sidedptosis and diplopia. Whole-body imaging revealed a mass in the pituitary fossa that was likely lymphomatous. Despite diagnostic uncertainty, the mass was treated as transformation of Marginal Zone Lymphoma to a high-grade lymphoma. This report analyses how and why the multi-disciplinary team treated the patient without a biopsy. The case highlights a possible...

Ascending aortic aneurysms are asymptomatic and are usually discovered as an incidental finding on chest imaging. However, larger aneurysms can present with symptoms resulting from compression of surrounding structures including the trachea, bronchi, and the esophagus which can result in hoarseness, cough chest pain or back pain. The presence of an aortic arch anomaly, specifically an aberrant right common carotid artery, in a background of an aortic arch aneurysm is extremely rare with a worldw...

Carotid paragangliomas are infrequent tumours, generally single, non-functional and benign. Nevertheless, the biology of these tumours occasionally means they are bilateral, multicentric, functional and malignant. Such infrequency and the different ways they manifest themselves pose a diagnostic/ therapeutic challenge that is reflected in the final outcomes. According to the Shamblin classification, 75% of carotid paragangliomas are either Type I (tumour smaller than 4 cm, weakly attached to the...

Individual HRDs are made up of small patient populations, thus the high individual prices will amount to a relatively small total cost to insurers and the healthcare system overall. Treatments for HRDs will, in almost all cases, represent the first and only available treatments. As the collective price will not be problematic and with treatments being the first available, insurers will have an incentive to cover the prices necessary to develop and commercialize these therapies....

The expectation that the introduction of modern cART against HIV, leading to viral suppression and functional cure, would also herald complete immunological recovery has not materialised. In reality, even with the most effective cART, complete immunological recovery is seldom achieved, especially, if initiated at later stages of the disease. Thus, patients who do not achieve full immunological recovery remain at increased risk of cancers, chronic immune activation, inflammation and impaired coag...
