Musculoskeletal Infections in the Emergency Department.

Bone and joint infections are potentially limb-threatening or even life-threatening diseases. Emergency physicians must consider infection when evaluating musculoskeletal complaints, as misdiagnosis can have significant consequences. Patients with bone and joint infections can have heterogeneous presentations with nonspecific signs and symptoms. Staphylococcus aureus is the most commonly implicated microorganism. Although diagnosis may be suggested by physical examination, laboratory testing, and imaging, tissue sampling for Gram stain and microbiologic culture is preferable, as pathogen identification and susceptibility testing help optimize long-term antibiotic therapy. A combination of medical and surgical interventions is often necessary to effectively manage these challenging infections.

Sub-acute Tamponade and the Value of Point-of-Care Ultrasound for Rapid Diagnosis: A Case Report.

Minoxidil is a strong oral vasodilator that is used to treat patients with hypertension refractory to first-line medications. We report a case of minoxidil-associated subacute cardiac tamponade diagnosed by point-of-care ultrasound (POCUS) in a hypertensive patient. A 30-year-old male with a past medical history of poorly controlled hypertension (treated with minoxidil) and chronic kidney disease presented with 2-3 days of chest pain and shortness of breath with markedly elevated blood pressures. A point-of-care transthoracic echocardiogram revealed a massive pericardial effusion with sonographic tamponade physiology. We review the risk factors for developing pericardial effusions that progress to cardiac tamponade, the utility of diagnosing these patients by POCUS, and the incidence of patients who present with sonographic signs of cardiac tamponade without hypotension.

A systematic guide for peer reviewers for a medical journal.

Performing a peer review of an article under consideration for publication requires not only an understanding of the subject matter, but also a systematic approach that includes screening for conflicts of interest; determining whether the manuscript is within or outside the reviewer's area of expertise; properly classifying the manuscript; and writing a detailed, organized review. Although some journals may provide guidelines for the reviewers, the guidelines usually are not detailed and do not take into consideration the variability in reviewer experience. This article is meant to serve as a guideline for peer reviewers and provide concrete information on how to write a comprehensive, unbiased review that will serve both the author and the journal well.

Late onset hearing loss: a significant complication of cancer survivors treated with Cisplatin containing chemotherapy regimens.

Cisplatin is a known ototoxic agent and has been associated with late onset hearing loss (LOHL) in children beyond completion of treatment. We completed a retrospective review of 160 patients yielding 59 who received cisplatin and had sufficient data to determine the presence of LOHL. LOHL was defined as a significant change in hearing thresholds 6 months past the last cisplatin therapy. A significant change was defined as a decrease of >15 dB in a frequency from 1 to 8 kHz in either ear, or a decrease of 10 dB at 2 or more frequencies in the same ear, compared with the previously entered audiogram. Hearing loss was classified using the Brock grading system for each ear. Of the 59 patients evaluated, 51% exhibited LOHL. Univariate analysis indicated LOHL was significantly associated with age of diagnosis (P=0.031), diagnosis of medulloblastoma (P=0.035), hearing aids (P=0.010), and cranial radiation (P=0.044), particularly to the posterior fossa (P=0.023). Multivariate analysis revealed only radiation to the posterior fossa (P=0.02) and the use of hearing aids (P=0.01) were significantly associated with LOHL. LOHL is a significant complication in childhood cancer survivors who receive cisplatin. Long-term audiologic monitoring after therapy is needed to identify the affected patients.
