Mission POCUS in Haiti.

Introduction: Point-of-care ultrasound (POCUS) has enhanced patient care and safety around the world. Clinicians can now use a small diagnostic ultrasound imaging device to answer some binary clinical questions and manage patients more effectively. Since the COVID-19 pandemic, there has been a significant adoption of POCUS by clinicians worldwide.

The external carotid artery as a rare feeder of a spinal dural arteriovenous fistula causing cervical myelopathy: A review of the literature.

Introduction: A causal relationship between SDAVF's and cervical myelopathy is exceedingly rare. 1-2% of these lesions are located at the craniocervical junction of which 12% are caused by arterial feeders from the external carotid artery. A correct diagnosis can be challenging with a high rate of initial misdiagnosis.

Spontaneous Swallowing Frequency, Dysphagia, and Drooling in Children With Cerebral Palsy.

Objective: To evaluate relationships between spontaneous swallowing frequency, dysphagia, and drooling in children with cerebral palsy. Spontaneous swallowing frequency was predicted to be inversely related to both dysphagia and drooling among children with cerebral palsy. A secondary objective compared patterns among spontaneous swallowing frequency, drooling, and age in healthy children vs children presenting with cerebral palsy.

Chordoid Glioma as a Differential Diagnosis of Anterior Third Ventricle Tumours: A Rare Case Report and Five-Year Follow-Up.

Chordoid glioma is a rare and relatively recently defined tumour entity. Worldwide there have only been around 90 cases described until now. A chordoid glioma comprises a low-grade suprasellar neuroepithelial neoplasm originating in the anterior part of the third ventricle, with consistent radiological features on MRI.

Glioblastoma with extracranial parotid, lymph node, and pulmonary metastases: a case report.

We present a rare case of an isocitrate dehydrogenase-wildtype glioblastoma with histologically proven parotid, cervical lymph node, and lung metastases. While recent therapy advances are likely to increase glioblastoma mid- and long-term survival, this will also increase the time window for extraneural glioblastoma spread. Radiologists should be aware of this risk, so they can accurately detect and interpret metastatic glioblastoma disease.

The diatom Phaeodactylum tricornutum adjusts nonphotochemical fluorescence quenching capacity in response to dynamic light via fine-tuned Lhcx and xanthophyll cycle pigment synthesis.

Diatoms contain a highly flexible capacity to dissipate excessively absorbed light by nonphotochemical fluorescence quenching (NPQ) based on the light-induced conversion of diadinoxanthin (Dd) into diatoxanthin (Dt) and the presence of Lhcx proteins. Their NPQ fine regulation on the molecular level upon a shift to dynamic light conditions is unknown. We investigated the regulation of Dd + Dt amount, Lhcx gene and protein synthesis and NPQ capacity in the diatom Phaeodactylum tricornutum after a change from continuous low light to 3 d of sine (SL) or fluctuating (FL) light conditions.

Hypothalamic hamartoma.

Hypothalamic hamartomas are rare congenital malformations presenting with central precocious puberty, gelastic epilepsy and developmental retardation. We report a case of an 11-month-old girl with recurring bloody vaginal discharge. Diagnosis of hypothalamic hamartoma was made on the basis of clinical findings and specific features on magnetic resonance imaging of the hypothalamic region.

Susac's syndrome: a clinical and radiological challenge.

We describe a patient with Susac's syndrome presenting with the triad of encephalopathy, branch retinal artery occlusion and hearing loss. MRI has some characteristic features and can be helpful in establishing the diagnosis, particularly in an early stage before the classic triad is complete. Besides MRI often allows to differentiate this rare disorder from more common neurologic diseases like multiple sclerosis.

Carpal boss syndrome.

Carpal boss is a bony prominence located dorsally on the base of the second and/or third CMC joint. We describe the imaging findings of the pathology in two patients and the relative contributive role of the different modalities and stress the decisive role of MRI.

Peroneal neuropathy after weight loss: a high-resolution ultrasonographic characterization of the common peroneal nerve.

Objective: The objective of this study was to use in vivo ultrasonographic imaging to analyze the common peroneal nerve in controls and patients who were diagnosed with peroneal neuropathy (PN) due to significant weight loss. We also looked for a relationship between weight loss (magnitude) and the occurrence of PN.

Materials And Methods: Fifty controls and six patients who were diagnosed with PN after losing a significant amount of weight were examined by means of ultrasonography (US).

Fast MR arthrography using VIBE sequences to evaluate the rotator cuff.

Purpose: The purpose of this paper was to evaluate if short volumetric interpolated breath-hold examination (VIBE) sequences can be used as a substitute for T1-weighted with fat saturation (T1-FS) sequences when performing magnetic resonance (MR) arthrography to diagnose rotator cuff tears.

Materials And Methods: Eighty-two patients underwent direct MR arthrography of the shoulder joint using VIBE (acquisition time of 13 s) and T1-FS (acquisition time of 5 min) sequences in the axial and paracoronal plane on a 1.0-T MR unit.

Functional magnetic resonance imaging for preoperative localisation of eloquent brain areas relative to brain tumours: clinical implementation in a regional hospital.

The purpose of this study was to evaluate the implementation of functional magnetic resonance imaging (fMRI) for clinical use in patients with a brain tumour in the setting of a regional hospital. Twenty-three patients underwent a fMRI examination as preoperative evaluation for a tumour adjacent to a eloquent brain area. The location and distance of the tumour relative to the fMRI activation area for this eloquent brain area was determined.

Organizational and health performance in small enterprises in Norway and Sweden.

This article focuses on relationships between organizational factors such as leadership, learning, psychosocial work environment and quality aspects as they relate to organizational and health performance outcomes in 42 small enterprises in Norway and Sweden. A rather explorative analysis model was created using indicators that were based on theoretical concepts from a literature review and questionnaire data, concerning 988 employees and leaders. These indicators were then used for correlation analysis.

Self-assessed changes in mental health and employment status as a result of unemployment training.

The main question addressed in this article is: What factors in an unemployment programme serve both the individual and society? Our research focuses on background variables and process variables and how these can be assumed to affect certain dependent variables in unemployment training. The current focus is on the dependent variable "subjective assessment of the effect of the training on mental health", together with the more objective dependent variable of "employment status after training". Self-confidence, well-being, faith in the future, level of initiative and personal development have been used as indicators of self-assessed "mental health".

T cell vaccination in multiple sclerosis patients with autologous CSF-derived activated T cells: results from a pilot study.

Myelin-reactive T cells are considered to play an essential role in the pathogenesis of multiple sclerosis (MS), an autoimmune disease of the central nervous system. We have previously studied the effects of T cell vaccination (TCV), a procedure by which MS patients are immunized with attenuated autologous myelin basic protein (MBP)-reactive T cell clones. Because several myelin antigens are described as potential autoantigens for MS, T cell vaccines incorporating a broad panel of antimyelin reactivities may have therapeutic effects.

A statistical human resources costing and accounting model for analysing the economic effects of an intervention at a workplace.

The study had two primary aims. The first aim was to combine a human resources costing and accounting approach (HRCA) with a quantitative statistical approach in order to get an integrated model. The second aim was to apply this integrated model in a quasi-experimental study in order to investigate whether preventive intervention affected sickness absence costs at the company level.

MRI in the assessment of pregnancy related intrauterine bleeding: a valuable adjunct to ultrasound?

MR imaging using ultrafast MR sequences is a useful method in assessing pregnancies at risk. This is especially the case for fetal imaging. However, reports of imaging of the placenta or the uterus are rare.

Diffusion-weighted MR imaging in the evaluation of renal infection: preliminary results.

Diffusion-weighted (DW) magnetic resonance imaging (MRI) has already gained status in the neuroradiological MRI approach of a patient suffering from a variety of neurological diseases. The clinical application of DW MRI in the evaluation of renal disease is not standard. This manuscript describes preliminary results of the application of DW imaging in renal infection to aid differential diagnosis and/or lesion detection in clinical MRI.

Longitudinal study of antimyelin T-cell reactivity in relapsing-remitting multiple sclerosis: association with clinical and MRI activity.

In multiple sclerosis (MS), T-cells are considered to be critical in coordinating an immunopathological cascade that results in myelin damage. We investigated whether clinical disease activity or brain inflammatory activity as measured by magnetic resonance imaging (MRI) was associated with changes in autoreactive T-cell reactivities in MS patients. To this end, a longitudinal study was performed in which T-cell-related immune parameters and clinical parameters (including MRI) were monitored in seven relapsing-remitting (RR) MS patients and two healthy controls with bimonthly intervals over a period of 18 months.
