Necrotizing Fasciitis and Mediastinitis after Wisdom Tooth Extraction: A Case Report

Jennifer Edwards, MD*, Ryan Fisher, MD* and Amrita Vempati, MD*

DOI: https://doi.org/10.21980/J8XW7KIssue 5:4[mrp_rating_result]
Computer tomography (CT) imaging of soft tissues of the neck and of the chest/abdomen/pelvis revealed extensive swelling and subcutaneous air (see red arrows) on the left side of the face and neck extending to the left shoulder, as well as parapharyngeal/retropharyngeal spaces and posterior/superior mediastinum.

Adult Clavicular Fracture Case Report

Jessica L Sea, PhD*, Nadia Zuabi, MD* and Alisa Wray, MD, MAEd*

DOI: https://doi.org/10.21980/J8FM0TIssue 5:4[mrp_rating_result]
The patient's chest and clavicular radiographs showed a comminuted displaced acute fracture of the right mid-clavicle (green, blue, yellow). The clavicular fracture was also visible on the chest computed tomography (CT). The remainder of his trauma workup was negative for acute findings.

Case Report of Distal Radioulnar Joint and Posterior Elbow Dislocation

Danielle Matonis, MD*, Katelyn Wittel, BS* and Alisa Wray, MD, MAEd*

DOI: https://doi.org/10.21980/J89S6K Issue 5:4[mrp_rating_result]
Radiographs of the left elbow and wrist were obtained. Left elbow radiographs showed simple posterolateral dislocation of the olecranon (red) without fracture of the olecranon (red) or trochlea (blue). Left wrist lateral radiographs demonstrated DRUJ dislocation with dorsal displacement of the distal ulna (green) without fracture or widening of the radioulnar joint (purple). Post-reduction radiographs demonstrated appropriate alignment of the elbow with the trochlea seated in the olecranon and improved alignment of the DRUJ.

Bladder Diverticulum – A Case Report

Savannah Tan, BS* and Sangeeta Sakaria, MD, MPH, MST*

DOI: https://doi.org/10.21980/J8635C Issue 5:4[mrp_rating_result]
On examination, the patient was alert and oriented but in mild distress. Suprapubic fullness was noted upon abdominal palpation. Point of care ultrasound of the bladder showed two enlarged “bladders” with a central communication. Bedside total bladder volume was measured to be 1288 cm3 (the top “bladder” was measured to be 1011 cm3, while the bottom “diverticulum” was measured to be 277 cm3) by ultrasound. The POCUS stills of the patient’s bladder demonstrated the bladder (red arrow) and bladder diverticulum (yellow arrow) with a central communication (blue arrow) in the transverse and sagittal views.

A Case Report of Ogilvie’s Syndrome in a 58-year-old Quadriplegic

Rosie Kumar, BS*, Brett Cowan, MD*, Daniel Quesada, MD* and Sage Wexner, MD*

DOI: https://doi.org/10.21980/J82922 Issue 5:4[mrp_rating_result]
Plain radiograph of the patient's abdomen revealed a gaseous distention of the colon. This is demonstrated as noted in the abdominal x-ray as gaseous distention, most notably in the large bowel (arrows) including the rectal region (large circle). Follow up computed tomography (CT) scan affirmed severe pancolonic gaseous distention measuring up to 11.2 cm, compatible with colonic pseudo-obstruction as noted by the large red arrows. No anatomical lesion or mechanical obstruction was observed, as well as no evidence of malignancy or other acute process.

Cecal Volvulus Diagnosed with a Whirl Sign: A Case Report

Gregory K Sun, DO* and Brian Walsh, MD*

DOI: https://doi.org/10.21980/J8XM05 Issue 5:4[mrp_rating_result]
The CT image demonstrates a “whirl sign” (red arrow) which is indicative of a volvulus. This image occurs when bowel, mesentery and vasculature rotate around a transition point causing an image similar to a hurricane on a weather map. When seen on a CT scan, a whirl sign suggests a high likelihood of either a closed loop bowel obstruction or volvulus in the cecum, sigmoid or midgut. In any of the cases, seeing a whirl sign strongly increases the need for emergent surgical management.

Paroxysmal Ventricular Standstill—A Case Report of all Ps and no QRS in Ventricular Asystole

Hamid Ehsani-Nia, DO* and Christopher Bryczkowski, MD*

DOI: https://doi.org/10.21980/J8SS79 Issue 5:4[mrp_rating_result]
In route, it was proposed that this patient was suffering from a dysrhythmia due to the transient episodes of syncope with lack of ventricular activity on telemetry. Upon close examination of the rhythm strips as well as the ECG, P waves can be visualized without any accompanying QRS complexes lasting multiple seconds (ED ECG blue arrows). Additionally, the rhythm has an intrinsic rate of 100 beats per minute and has a consistent morphology with no evidence of ventricular activity due to the lack of QRS complexes. As a result, the rhythm likely originates in the atria with no passage of impulses into the ventricles through the atrioventricular (AV) node versus an accelerated ventricular rhythm where QRS complexes would be seen.8 These rhythm strips demonstrate an example of VS. There is preserved native atrial automaticity, with an intact sinoatrial (SA) node, with a complete lack of ventricular electrical activity

Severe Hyperkalemia

Daniel Johnson, DO* and Dan Wiener, MD*

DOI: https://doi.org/10.21980/J8KH1D Issue 5:3[mrp_rating_result]
The initial ECG obtained upon arrival shows what is commonly referred to as a sine wave pattern. This patient does have a biventricular pacemaker which would ordinarily create a wide QRS complex mimicking an intraventricular conduction delay. However, the QRS complex here is exceptionally wide, in excess of 400 milliseconds (normal: less than 120 milliseconds). As the QRS widens, alongside other deflections present on the ECG, it morphologically mimics a mathematical sine wave.
