Sixty-one percent of respondents indicated that external personnel in the MR environment are a safety risk. External personnel in the MR environment were found to be a predictor for reported and unreported MR-related incidents with odds ratio (OR) = 2.07; p = 0.033 and OR = 5.17; p = 0.0005 respectively. CONCLUSION There seems to be severe underreporting of MR-related incidents. External personnel in the MR-environment and scanning patients in anaesthesia were found to be predictors for both reported and unreported MR-related incidents. Regulations regarding the minimum required MR safety education of different groups of MR professionals and external personnel are recommended. IMPLICATIONS FOR PRACTICE Enforcing MR safety education and highlighting the importance of MR safety within hospital organisations would contribute to better patient and personnel safety. The structures of the bovine and human BBSome reveal that a conformational change is required to recruit the complex to the ciliary membrane. © 2020, Petriman and Lorentzen.Clustered ion channels at nodes of Ranvier are critical for fast action potential propagation in myelinated axons. Axon-glia interactions converge on ankyrin and spectrin cytoskeletal proteins to cluster nodal Na+ channels during development. However, how nodal ion channel clusters are maintained is poorly understood. Here, we generated mice lacking nodal spectrins in peripheral sensory neurons to uncouple their nodal functions from their axon initial segment functions. We demonstrate a hierarchy of nodal spectrins, where β4 spectrin is the primary spectrin and β1 spectrin can substitute; each is sufficient for proper node organization. Remarkably, mice lacking nodal β spectrins have normal nodal Na+ channel clustering during development, but progressively lose Na+ channels with increasing age. Loss of nodal spectrins is accompanied by an axon injury response and axon deformation. Thus, nodal spectrins are required to maintain nodal Na+ channel clusters and the structural integrity of axons. © 2020, Liu et al.STUDY OBJECTIVES This study aimed to determine the prevalence of sleep-disordered breathing and its association with malocclusion among children in Recife, Brazil. METHODS This study included 390 children aged seven to eight years. The data comprised the measurement of body mass, orthodontic examination, and parental information required by the Sleep Disturbance Scale for Children. selleck compound The statistics tools used were Pearson's chi-square test and the Lemeshow test. RESULTS Positively screened for SDB was found in 33.3% of the children, and the association with overjet was p = 0.007 (OR - 95% CI 1,93). The association with anterior open bite was p = 0.008 (OR - 95% CI 2,03), and the association with posterior crossbite was p = 0.001 (OR - 95% CI 2,89). This report was unable to indicate an association between body mass index and sleep-disordered breathing. The multivariate logistic regression model revealed that the anterior open bite (p = 0.002/ OR - 95% CI 2,34) and posterior crossbite (p = 0.014 / OR - 95% CI 2,79) had an association with positively screened for SDB. CONCLUSIONS The results of this study indicated that the prevalence of sleep-disordered breathing was high and highly associated with malocclusion. Since posterior crossbite and anterior open bite were associated with positively screened for SDB, early diagnosis and intervention may prevent and minimize adverse effects of SDB on individuals lives. © 2020 American Academy of Sleep Medicine.In this case report, a 14-year-old male presented with episodes of migraine-like headaches preceded by unilateral hemiparaesthesia, hemiparesis, confusion, and dysphasia with the last two lasting more than four hours. The cerebrospinal fluid (CSF) showed lymphocytosis with no detectable aetiology, neuroimaging was normal, and an electroencephalogram showed diffuse slowing. The patient was diagnosed with headache associated with neurologic deficits and CSF lymphocytosis, i.e. syndrome of transient headache and neurologic deficits with cerebrospinal fluid lymphocytosis. The condition is a rare disorder, especially in children. Normally, a complete remission takes place within few weeks to months without treatment.This review summarises the current knowledge of ejaculatory dysfunction, which is a group of prevalent sexual disorders with a substantial impact on sexual health of men and their partners. A thorough medical history is the most important evaluation tool. Several treatments for premature ejaculation are available; however, a successful treatment outcome depends on pre-treatment alignment of expectations. Infertility due to delayed ejaculation, retrograde ejaculation or anejaculation can be treated effectively.This review summarises the knowledge of catatonia, which is a neuropsychiatric syndrome with altered psychomotor and behavioural symptoms as well as autonomic dysfunction seen in a variety of psychiatric, neurologic and medical conditions. However, catatonia frequently remains unrecognised by clinicians. The classification of catatonia differs significantly in the international classifications, reflecting the controversy regarding the concept of catatonia and its complex symptomatology. Different rating scales are developed to diagnose catatonia in clinical practice. First-choice treatment is benzodiazepines and ECT regardless of underlying condition.In this review, we discuss genital herpes - a common sexually transmitted infection, which can be transmitted to the baby during birth. Neonatal herpes is a rare but serious infection. In 2019, the Danish Society of Obstetrics and Gynecology revised the guideline for management of genital herpes in pregnancy. Recommendations include antiviral therapy from gestational week 36 in case of primary- or recurrent infection in current pregnancy. Delivery by cesarean section is recommended in case of primary infection in the third trimester. Women with recurrent herpes can deliver vaginally, as risk of neonatal infection is low.This review covers the possible treatment modalities of organic erectile dysfunction (ED). About 30% of men over 40 years of age suffer from ED. At diagnosis, organic ED should be distinguished from psychological ED, and it is crucial to identify underlying diseases including endocrine disorders, neurological problems and cardiovascular diseaplase. Management of organic ED is initiated by treating such underlying problems, and lifestyle changes are central. Symptomatic treatments include tablets, injections, intraurethral medication, vacuum pumps, and penile implants. Current research focuses on regenerative medicine, which may play a future role.This case report describes a 63-year-old woman, who had an undiscovered os odontoideum for three years and underwent therapy by a chiropractor and a physiotherapist, before the diagnosis was made. Os odontoideum is unknown to most doctors, and increased knowledge of the disease is of great importance, since inappropriate treatment in the form of manipulation and neck exercises might worsen the disease. In case of prolonged or uncharacteristic neck symptoms, the diagnosis should be considered, and a normal cervical X-ray would provide the diagnosis. If os odontideum is suspected, the patient should be referred to a highly specialised spine centre at a university hospital.Essential tremor can be a debilitating disease. In many cases, medical treatment is ineffective and/or holds significant side effects. Surgical treatment using deep brain stimulation is only possible in few and selected cases. The introduction of MR-guided focused ultrasound enables surgeons to make small and specific lesions in the thalamus with few side effects and limited risk for the patient. The effectiveness has been documented in several international studies and is summarised in this review.In recent years, gene therapy has resurged as a potential treatment for an increasing number of medical diseases including those affecting the central nervous system (CNS), which is discussed in this review. link2 Clinical trials have revealed promising results particularly in gene therapy for Parkinson's disease with upregulation of dopamine synthesis or downregulation of huntingtin synthesis in Huntington's disease. Gene therapy for spinal motor atrophy has received FDA approval this year. The biggest success is seen in ophthalmology, where gene therapy has been FDA/EU-approved for retinitis pigmentosa, sparking further hope of use for other CNS diseases in a near future.This case report describes a 53-year-old woman, who presented with symptoms of a perilymphatic fistula (PLF), developed 12 years after most recent surgery. The diagnosis was confirmed by a combination of clinical observations, temporal computed tomography, audiometry and video head impulse test. PLF normally occurs after traumatic lesions or substantial infections of the middle ear, often including cholesteatomas, and should be suspected when patients with the relevant clinical history present with sudden onset of unilateral hearing loss, dizziness, tinnitus and aural fullness.Localised amyloidosis in the urinary tract is a rare and often benign condition, which is usually clinically mistaken for malignancy. I this case report, a 48-year-old man was referred to the hospital with left flank pain, and CT-urography showed a tumour with calcification in the distal ureter. During transurethral procedure, the tumour was resected macroscopically. Histology revealed the diagnosis of amyloidosis. Follow-up was without signs of systemic involvement or recurrence. This case underlines the significance of preoperative diagnostic biopsy, thus saving the patient from unnecessary major surgery.The native rat lungworm (Angiostrongylus mackerrasae) and the invasive rat lungworm (Angiostrongylus cantonensis) occur in eastern Australia. link3 The species identity of A. mackerrasae remained unquestioned until relatively recently, when compilation of mtDNA data indicated that A. mackerrasae sensu Aghazadeh et al. (2015b) clusters within A. cantonensis based on their mitochondrial genomes (mtDNA). To re-evaluate the species identity of A. mackerrasae, we sought material that would be morphologically conspecific with A. mackerrasae. We combined morphological and molecular approaches to confirm or refute the specific status of A. mackerrasae. Nematodes conspecific with A. mackerrasae from Rattus fuscipes and Rattus rattus were collected in Queensland, Australia. Morphologically identified A. mackerrasae voucher specimens were characterized using amplification of cox1 followed by the generation of reference complete mtDNA. The morphologically distinct A. cantonensis, A. mackerrasae and A. malaysiensis are genetically distinguishable forming a monophyletic mtDNA lineage. We conclude that A. mackerrasae sensu Aghazadeh et al. (2015b) is a misidentified specimen of A. cantonensis. The availability of the mtDNA genome of A. mackerrasae enables its unequivocal genetic identification and differentiation from other Angiostrongylus species.OBJECTIVE To evaluate the National Health Safety Network (NHSN) hospital-onset Clostridioides difficile infection (HO-CDI) standardized infection ratio (SIR) risk adjustment for general acute-care hospitals with large numbers of intensive care unit (ICU), oncology unit, and hematopoietic cell transplant (HCT) patients. DESIGN Retrospective cohort study. SETTING Eight tertiary-care referral general hospitals in California. METHODS We used FY 2016 data and the published 2015 rebaseline NHSN HO-CDI SIR. We compared facility-wide inpatient HO-CDI events and SIRs, with and without ICU data, oncology and/or HCT unit data, and ICU bed adjustment. RESULTS For these hospitals, the median unmodified HO-CDI SIR was 1.24 (interquartile range [IQR], 1.15-1.34); 7 hospitals qualified for the highest ICU bed adjustment; 1 hospital received the second highest ICU bed adjustment; and all had oncology-HCT units with no additional adjustment per the NHSN. Removal of ICU data and the ICU bed adjustment decreased HO-CDI events (median, -25%; IQR, -20% to -29%) but increased the SIR at all hospitals (median, 104%; IQR, 90%-105%).
