Subcutaneous emphysema of a limb after acute injury is classically associated with gas gangrene. Delayed management can result in amputation and death. Typically caused by a clostridial infection, patients are unwell, with rapidly spreading clinical signs, abnormal laboratory results, and cultures positive. There are reports of widespread subcutaneous emphysema of a limb in well-appearing patients, with blood parameters within normal limits; however, the optimum management of this type of case is unclear. ⋯ Here we present a case series of 4 patients, all with penetrating injuries to the upper limb resulting in widespread subcutaneous emphysema within 24 h of injury. Mean age was 33 years. All were fit and well, with the exception of one with type 1 diabetes, no cardiorespiratory compromise, and no significant derangement of laboratory investigations. X-ray studies showed widespread gas within the soft tissues. All were treated aggressively with immediate surgical fasciotomy of the upper limb, thorough debridement, and washout as required. Gram stains revealed pus cells (polymorphonuclear leucocytes) in all, but organisms in only one case (Gram-positive cocci and bacilli). Prolonged culture grew organisms in all. All patients had a second washout and closure plus 6 weeks of antibiotics. All survived and had fully functioning limbs. Why should an emergency physician be aware of this? We recommend having a low threshold for rapid referral to an appropriate surgical speciality, allowing prompt and radical surgical management of this type of presentation, even in the presence of a well patient.

Bedside ultrasound (US) is associated with improved patient satisfaction, perhaps as a consequence of improved time to diagnosis and decreased length of stay (LOS). ⋯ Patients who had a bedside US had statistically significant higher satisfaction scores with overall ED care, diagnostic testing, and with their perception of the emergency physician. Bedside US has the potential not only to expedite care and diagnosis, but also to maximize satisfaction scores and improve the patient-physician relationship, which has increasing relevance to health care organizations and hospitals that rely on satisfaction surveys.

Emergency Cesarean Section Due to Acute Aortic Dissection Type A (Debakey I) without Marfan Syndrome: A Case Report and Review of the Literature.
Acute aortic dissection during pregnancy is an uncommon but important emergency due to its lethal risk to both mother and child. The dissection usually involves the ascending aorta or the aortic arch. Although additional affection of the descending aorta up to bifurcation is possible, further increasing the risk of organ malperfusion, full-length aortic dissection (DeBakey I) is known to be very rare. Dissection during pregnancy has been reported predominantly in combination with Marfan syndrome. Acute aortic dissection Stanford type A (AADA) DeBakey I during pregnancy without signs of Marfan syndrome as a warning signal is very uncommon in the current literature. ⋯ This alarming result of AADA (DeBakey I) in late pregnancy without obvious warnings such as Marfan syndrome illustrates the importance of performing early imaging in similar cases.

Lumbar puncture (LP) is a commonly performed procedure in pediatrics. Accurate analysis of cerebrospinal fluid (CSF) profile is essential in diagnosing and managing a variety of infectious and inflammatory conditions involving the brain, meninges, and spinal cord. It can also provide useful diagnostic information in the evaluation of possible subarachnoid hemorrhage and demyelinating syndromes, and aid in the diagnosis and management of pseudotumor cerebri. ⋯ A thorough understanding of anatomic, physiologic, and pathologic considerations regarding performing lumbar puncture and CSF analysis can augment success in diagnosing a variety of potentially serious pediatric conditions.

Cardiac syncope is associated with poor outcomes and may result in traumatic injuries. In patients presenting to the emergency department (ED) with trauma, recognizing the cause of syncope is particularly challenging. Also, clinical markers to identify cardiac syncope are not well established. ⋯ In patients with traumatic falls and syncope, simple clinical and electrocardiographical variables may identify patients with cardiac causes of syncope. Proper identification of cardiac syncope in this population can potentially prevent recurrence of life-threatening traumatic injury.
