Pneumomastia following subdermal upper arm helium contouring treatment.

Unlabelled: A case is presented of extensive pneumomastia seen on a screening mammogram of an asymptomatic patient who had helium plasma treatment 2 weeks earlier for flabby upper arms.

Contribution: Rare complications of subcutaneous emphysema, following helium plasma treatment, have been discussed to highlight that such emphysema is usually self-limiting.

Choline Supplementation Does Not Promote Atherosclerosis in CETP-Expressing Male Apolipoprotein E Knockout Mice.

Dietary trimethylamines, such as choline, metabolized by intestinal microbiota to trimethylamine are absorbed by the gut and oxidized to trimethylamine N-oxide (TMAO). The objective of this study was to determine the effect of choline supplementation on atherosclerosis progression in mice expressing human cholesterol ester transfer protein (hCETP) using the same diets as in previously reported studies. Mice expressing hCETP, after transfection with AAV2/8-hCETP, were fed an 18% protein diet with either 0.

Perspective: Estrogen and the Risk of Cognitive Decline: A Missing Choline(rgic) Link?

Factors that influence the risk of neurocognitive decline and Alzheimer's disease (AD) may provide insight into therapies for both disease treatment and prevention. Although age is the most striking risk factor for AD, it is notable that the prevalence of AD is higher in women, representing two-thirds of cases. To explore potential underlying biological underpinnings of this observation, the intent of this article is to explore the interplay between cognitive aging and sex hormones, the cholinergic system, and novel hypotheses related to the essential nutrient choline.

Free Tarsal Graft and Free Skin Graft for Lower Eyelid Reconstruction.

Purpose: To determine whether reconstruction of lower eyelid defects involving the eyelid margin with a free tarsal graft and an overlying free skin graft, without retention or provision of any vascular support, would yield acceptable functional and cosmetic results.

Methods: We present here a clinical series of 4 patients treated between April 2019 and September 2019 who underwent reconstruction of large postcarcinoma excision, eyelid-margin-inclusive eyelid defects. Surgery was performed by the same surgeon (J.

Challenges in the Diagnosis of Magnesium Status.

Magnesium is a critical mineral in the human body and is involved in ~80% of known metabolic functions. It is currently estimated that 60% of adults do not achieve the average dietary intake (ADI) and 45% of Americans are magnesium deficient, a condition associated with disease states like hypertension, diabetes, and neurological disorders, to name a few. Magnesium deficiency can be attributed to common dietary practices, medications, and farming techniques, along with estimates that the mineral content of vegetables has declined by as much as 80⁻90% in the last 100 years.

Secretory Carcinoma of the Lacrimal Gland: A Rare Case Report.

Secretory carcinoma is a salivary gland malignancy that recapitulates secretory carcinoma of the breast, along with its shared ETV6-NTRK3 gene fusion. Characterization of histopathologic, immunohistochemical, and molecular genetic features of this neoplasm has led to reclassification of a heterogeneous group of salivary gland carcinomas as secretory carcinoma and to identification of this neoplasm in other gland-containing tissues. The authors describe a 52-year-old man who presented with a 2-week history of diplopia and a well-circumscribed right orbital mass.

[Structure and functioning of research ethics committees in the Autonomous City of Buenos Aires and Greater Buenos Aires].

Given the few existing studies on research ethics committees (RECs) in Argentina, this paper aims to describe the structure and functioning of institutional RECs in the Autonomous City of Buenos Aires and Greater Buenos Aires. A descriptive, qualitative and quantitative research study was carried out using a survey conducted between March and July 2012. The sample was made up of 46 RECs.

Relationships between the generalized functional method and other methods of nonimaging optical design.

The recently developed generalized functional method provides a means of designing nonimaging concentrators and luminaires for use with extended sources and receivers. We explore the mathematical relationships between optical designs produced using the generalized functional method and edge-ray, aplanatic, and simultaneous multiple surface (SMS) designs. Edge-ray and dual-surface aplanatic designs are shown to be special cases of generalized functional designs.

Thermodynamic efficiency of solar concentrators.

The optical thermodynamic efficiency is a comprehensive metric that takes into account all loss mechanisms associated with transferring flux from the source to the target phase space, which may include losses due to inadequate design, non-ideal materials, fabrication errors, and less than maximal concentration. We discuss consequences of Fermat's principle of geometrical optics and review étendue dilution and optical loss mechanisms associated with nonimaging concentrators. We develop an expression for the optical thermodynamic efficiency which combines the first and second laws of thermodynamics.

Nurse leader mindfulness meditation program for stress management: a randomized controlled trial.

Objective: The aim of this study was to rigorously evaluate a brief stress management intervention for nurse leaders.

Background: Despite the nursing shortage, evidence-based workplace approaches addressing nurse stress have not been well studied.

Methods: Nurse leaders (n = 33) were randomly assigned to brief mindfulness meditation course (MMC) or leadership course (control).

Neuropsychiatric and memory issues in epilepsy.

Epilepsy is an extremely complex disorder characterized by marked variability in clinical presentation, etiology, diagnostic certainty, and therapeutic options. Neuropsychiatric and cognitive concomitant disorders are equally diverse and complex. Depression and anxiety, for example, may be preexisting conditions, occur only in peri-ictal or ictal states, or persist as constant interictal phenomena; both place additional burden on memory functions, which are further taxed by the effects of recurrent seizures, temporal lobe insult, and antiseizure medications.

A pilot study of donepezil for memory problems in epilepsy.

We performed a pilot 3-month, open-label study of 5-10 mg donepezil, an anticholinesterase inhibitor, as treatment for memory problems in people with epilepsy. The Buschke Selective Reminding Test was administered at baseline and after 3 months of donepezil. In 18 completing patients, the total number of words recalled across learning trials was greater on donepezil (P = 0.

Neurocysticercosis: nursing perspectives.

Management of neurocysticercosis (NCC) is mostly by means of prevention and antihelminthic medications. We reviewed the role of medical and surgical intervention in patients with NCC lesions. We also identified two patients with isolated NCC lesions to determine whether they might be rendered seizure free through surgical removal of the lesion.

Is there a neurologist on this flight?

Objective: To analyze the frequency of neurologic events during commercial airline flights and to assess whether onboard emergency medical kits are adequate for in-flight neurologic emergencies.

Methods: Collaboration of the Mayo Clinic's Departments of Emergency Medicine and Medical Transportation Service and the Division of Aerospace Medicine to provide real-time in-flight consultation to a major US airline that flies approximately 10% of all US passengers. We analyzed all medical events reported from 1995 to 2000 in a database that catalogs the air-to-ground medical consultations.

Musical hallucinations associated with seizures originating from an intracranial aneurysm.

Hallucinations are defined as sensory phenomena in the absence of external sensory stimuli. Auditory hallucinations have been shown to arise from many different intracranial lesions, but seizures manifesting as musical hallucinations triggered by unruptured intracranial aneurysms are rare. We present a case of persistent, episodic musical hallucinations associated with seizures that led to the discovery of 2 small intracranial aneurysms.

Parental report of sleep problems in children with attentional and learning disorders.

This study examined whether parents of children diagnosed with neurodevelopmental disorders (n = 79) report greater sleep-related problems in their offspring than do parents of normal community-based children (n = 86) on a research questionnaire developed to assess sleep and breathing problems, sleepiness, and behavioral problems. Clinical subgroups included: attention deficit/hyperactivity disorder (ADHD) (n = 43), learning disabilities (LD) (n = 11), and combined ADHD/LD (n = 25). Analyses revealed that parents of children with neurodevelopmental disorders report greater problems along all three dimensions than parents of normal control children.

Suspected malingering and the Digit Memory Test: a replication and extension.

This study replicated a previous finding that suspected malingerers often perform at a level worse than patients with unequivocal brain dysfunction on the Digit Memory Test (DMT). In addition, it was demonstrated that patients suffering from aphasia as well as temporal and "frontal lobe" damage perform at a level higher than suspected malingerers. DMT performance of patients with true dementia, however, may be difficult to distinguish from suspected malingerers.

Patient awareness of seizures.

In 31 consecutive patients who were admitted to an epilepsy monitoring unit, we prospectively determined whether the patients were aware of having seizures. On admission, all patients stated that they knew of at least some of their seizures. Eight of 23 with classifiable epileptic seizures recognized that they were occasionally unaware of their seizures.

Differential response characteristics in nonepileptic and epileptic seizure patients on a test of verbal learning and memory.

Investigators have found it difficult to separate patients with nonepileptic seizures (NES) from those with true epileptic seizures (ES) using quantitative measures of neuropsychological test performance. We examined qualitative response characteristics on the California Verbal Learning Test of 41 patients undergoing continuous video/audio-EEG monitoring in an effort to distinguish these patient groups (12 patients with left temporal [LT] foci, 11 with right temporal [RT] foci, and 18 with NES). NES patients explicitly recognized fewer target words compared with ES patients.

[Ideas on health and the environmental air. A comparative study between ancient and medieval medical texts].

The present work is designed to foster the understanding of traditional phenomena and the pattern of changes in the historical transmission of scientific knowledge from the classical antiquity until the Middle Ages. A comparative study is made here of the ideas championed by the classical Greek-Roman and the Hebrew medicine on one side and Maimonides's doctrine on the other, as regards the influence of the environmental air and the wind on the people's health. It results from the analysis of different texts that Maimonides had a very deep knowledge of the main works of both schools and that he was able to fully systematize the knowledge extant on that subject at his time while he did not bring in innovations of any special importance on the matter.
