Spinal cord involvement is rare in neuro-listeriosis and there no previous paediatric reports of Listeria-related myelitis or demyelinating polyneuropathy. The mechanism behind these presentations is unclear but an auto-immune response to the infection might be considered.

Nonketotic hyperglycinemia (NKH) is the most common metabolic cause of EME and genetic testing confirms the diagnosis of NKH in around 75% of the patients with a clinical diagnosis of NKH. Three genes are known to cause NKH. Here we describe a case of EME caused by NKH in which a new mutation in aminomethyltransferase (AMT) gene has been detected.
Oncoplastic surgery of the breast has generated great excitement over the past years and has become an integrated component of the surgical treatment of breast cancer. Oncoplastic procedures (OPP) associate the best surgical oncologic principles to achieve wide tumor-free margins with the best principles of plastic surgery to optimize cosmetic outcomes. Thanks to oncoplastic techniques, the role of breast conserving surgery (BCS) has been extended to include a group of patients who would otherwise require mastectomy to achieve adeguate tumor clearance. However, even with the use of OPP, cosmetic outcomes may result unsatisfying when a large volume of parenchyma has to be removed, particularly in small-medium size breasts. Recently, it has been proposed the use of ORC (Oxidized Regenerated Cellulose) as a reconstructive biomaterial to optimize the aesthetic results after OPP. The aim of this article is to describe the standard pattern of an innovative surgical oncoplastic technique with ORC, that we have called "QUORC" (QUadrantectomy with Oxidized Regenerated Cellulose), to improve cosmetic results and minimize the possible postoperative complications.

Arterial gas embolism (AGE) is a major cause of morbidity and mortality in self-contained underwater breathing apparatus (SCUBA) diving and certain medical procedures. There are currently no well-defined criteria to diagnose AGE. Emergency physicians often find themselves facing a decision whether or not a patient with dive-related symptoms has an AGE and needs to be transferred to a hyperbaric facility.

The objective of this study was to test the accuracy of diagnostic criteria developed by the San Diego Hyperbaric Oxygen Group (SANDHOG) for the diagnosis of AGE.

This was a retrospective review of consultations completed by the Hyperbaric Medicine Department (HBO) at the University of California San Diego where the diagnosis of AGE was considered. HBO staff blinded to the purpose of the study identified potential cases of AGE. The criterion standard was the final diagnosis by a panel of HBO specialists also blinded to the purpose of this study. Descriptive statistics and comparisons evaluating SANDHOG ther examine and validate the accuracy and inter-rater reliability of this tool.
The SANDHOG criteria appear to be reliable in diagnosing AGE. click here AGE is unlikely with SANDHOG scores less then 2, whereas SANDHOG scores ≥2 resulted in high sensitivity and specificity for AGE. Emergency physicians may find this tool useful in evaluating patients for suspected AGE, and it may assist in determining whether to transfer the patient to a hyperbaric facility. Future studies should be performed to further examine and validate the accuracy and inter-rater reliability of this tool.
We present the case of the youngest known patient diagnosed with surfer's myelopathy. Surfer's myelopathy is a rare nontraumatic myelopathy. The most likely etiology, presumably, is arterial insufficiency related to spine hyperextension. Symptoms consist of back pain, urinary incontinence or retention, paraplegia, and sensory loss.

A 7-year-old girl presented with back pain, urinary retention, and lower extremity weakness after doing backbends during a cheerleading practice the day prior to presentation. WHY SHOULD AN EMERGENCY MEDICINE PHYSICIAN BE AWARE OF THIS? With the trend of children becoming increasingly active in competitive sports at a younger age, surfer's myelopathy is a diagnosis that should be considered when the symptoms are present and the history consists of hyperextending the back. As in our case, a seemingly benign trauma can lead to the diagnosis of surfer's myelopathy.

One of the Healthy People 2010 goals was to eliminate racial disparities in the U.S health system. To date, we have limited knowledge about the impact of Healthy People on racial disparities at emergency departments (EDs).

We sought to investigate whether there has been an improvement in ED waiting time to see a physician for African Americans (AAs) compared to whites with chest pain symptoms that suggest acute coronary syndrome (ACS).

A retrospective analysis of the National Hospital and Ambulatory Care Survey data from 2004 to 2011 was conducted in adults with visits related to ACS. We compared covariate-adjusted odds ratios for race for each study year and 2011. In addition, adjusted average differences in waiting times (i.e., time to see a physician) for AAs and whites for each study year were compared.

A total of 15,438 visits related to ACS symptoms were made during the study period. The waiting time for AAs (median, 33min) was statistically longer compared to whites (median, 21min). In additionearch is warranted to investigate the underlying reasons for unequal care offered to AAs at EDs and the implications on disease outcome.
Low back pain is extremely common and usually a minor self-limiting condition. Rarely, however, it is a harbinger of serious medical illness. Paraspinal compartment syndrome is a rare condition, but its timely recognition is important to allow adequate treatment.

A 16-year-old boy presented to the Emergency Department (ED) with severe low back pain, necessitating intravenous opioids. Laboratory results showed severe rhabdomyolysis. Magnetic resonance imaging of the lumbar spine showed diffuse edema and swelling in the paraspinal muscles. Aggressive fluid therapy was started but despite narcotic analgesia the pain persisted and creatine kinase (CK) levels increased. Compartment pressures of the erector spinae were found to be increased. The decision was made to proceed with bilateral paraspinal fasciotomies. Postoperatively, the patient noted immediate pain relief with rapid decrease of CK level. link2 The patient is pain free and resumed running and swimming 3 months after admission in the ED. WHY SHOULD AN EMEy, the patient noted immediate pain relief with rapid decrease of CK level. The patient is pain free and resumed running and swimming 3 months after admission in the ED. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? Although paraspinal compartment syndrome is a rare condition, its recognition is of paramount importance to allow adequate surgical treatment, preventing muscle necrosis. Although back pain most often has a benign course, a careful history and physical examination in patients presenting with low back pain allows determination of "red flags." Mandatory further diagnostic tests can identify underlying serious illness.
Research indicates that licensed health care workers are less willing to work during a pandemic and that the willingness of nonlicensed staff to work has had limited assessment.

We sought to assess and compare the willingness to work in all hospital workers during pandemics and earthquakes.

An online survey was distributed to Missouri hospital employees. Participants were presented with 2 disaster scenarios (pandemic influenza and earthquake); willingness, ability, and barriers to work were measured. T tests compared willingness to work during a pandemic vs. link3 an earthquake. Multivariate linear regression analyses were conducted to describe factors associated with a higher willingness to work.

One thousand eight hundred twenty-two employees participated (15% response rate). More willingness to work was reported for an earthquake than a pandemic (93.3% vs. 84.8%; t = 17.1; p < 0.001). Significantly fewer respondents reported the ability to work during a pandemic (83.5%; t = 17.1; p < 0.001) or an earthquake (89.8%; t = 13.3; p < 0.001) compared to their willingness to work. From multivariate linear regression, factors associated with pandemic willingness to work were as follows 1) no children ≤3 years of age; 2) older children; 3) working full-time; 4) less concern for family; 5) less fear of job loss; and 6) vaccine availability. Earthquake willingness factors included 1) not having children with special needs and 2) not working a different role.

Improving care for dependent family members, worker protection, cross training, and job importance education may increase willingness to work during disasters.

In this work, the impact of various in vitro culture parameters on primary adult murine organoid formation and growth are analyzed with a focus on matrix properties and geometric culture configuration. The air-liquid interface culture configuration was found to result in enhanced organoid formation relative to a traditional submerged configuration. Additionally, through use of a recombinantly engineered extracellular matrix (eECM), the effects of biochemical and biomechanical cues were independently studied. Decreasing mechanical stiffness and increasing cell adhesivity were found to increase organoid yield. Tuning of eECM properties was used to obtain organoid formation efficiency values identical to those observed in naturally harvested collagen I matrices but within a stiffer construct with improved ease of physical manipulation. Increased ability to remodel the surrounding matrix through mechanical or enzymatic means was also shown to enhance organoid formation. As the engineering and tunability of recombinant matrices is essentially limitless, continued property optimization may result in further improved matrix performance and may help to identify additional microenvironmental cues that directly impact organoid formation, development, differentiation, and functional behavior. Continued culture of primary organoids in recombinant matrices could therefore prove to be largely advantageous in the field of intestinal tissue engineering for applications in regenerative medicine and in vitro tissue mimics.
