Small Bowel in Vagina: A Case for Pelvic Exams.

Vaginal cuff dehiscence with small bowel evisceration is a serious but uncommon postoperative complication of total laparoscopic hysterectomies. The severity of surgical site dehiscence can range from small, partial to full-thickness wound dehiscence, manifesting with acute abdominal pain, vaginal bleeding, or discharge, and is often precipitated by sexual intercourse. While imaging, including a pelvic ultrasound and computed tomography (CT), may help in undifferentiated acute abdominal pain, vaginal cuff dehiscence remains a clinical diagnosis found on physical exam. Because vaginal cuff dehiscence is a clinical diagnosis, sparse data exist regarding radiographic sensitivities and specificities in the identification of vaginal cuff dehiscence. Despite the increasing literature suggesting that pelvic exams are invasive with often limited utility, the authors argue that pelvic exams remain essential in identifying complications of hysterectomies. The authors present a case of a 40-year-old woman with acute abdominal pain found to have loops of small bowel in the vaginal vault, discovered only on physical exam after negative CT and ultrasound imaging.

Retropharyngeal Abscess With Severe Airway Compromise Following Anterior Cervical Spine Surgery: A Case Report.

Anterior cervical corpectomy, discectomy, and fusion are common surgical management options for symptomatic cervical radiculopathy and myelopathy. While these procedures are common and well-tolerated, postoperative complications span from mild dysphasia to airway compromise secondary to retropharyngeal or peri-cervical space abscess. These critical patients require robust airway management, which may entail a multidisciplinary approach or airway management in the operating room. We describe a patient who developed airway compromise 10 days following anterior cervical discectomy and fusion with a pre-platysmal abscess and a large retropharyngeal abscess. These abscesses were large enough to cause a mass effect with tracheal deviation. This deviation was severe enough that the patient required awake incision and drainage prior to rapid sequence intubation.

Guanfacine toxic ingestion with subsequent cardiogenic pulmonary edema.

Guanfacine is a central alpha-2 agonist often prescribed for Attention-deficit hyperactive disorder as well as tic disorder, with a usual dose of 1-4 mg per day. Due to its sympatholytic mechanism of action, Guanfacine can cause autonomic instability and hypotension. It can additionally cause cardiac dysfunction to include symptomatic bradycardias and contractility suppression. The authors present a case of a 17 year-old male with an ingestion of 80 mg of extended release Guanfacine with delayed onset cardiogenic pulmonary edema requiring mechanical ventilation. Previous pediatric ingestions have generated bradycardia, hypotension, and decreased level of consciousness, responsive to intravenous fluids, vasopressors, and occasionally naloxone. However, cardiogenic pulmonary edema from reduced cardiac contractility is a novel consequence of extended release Guanfacine ingestion. With Guanfacine's extended half-life, this unique case underscores the importance of emergency providers' familiarity with this toxidrome as well the necessity for prolonged, close observation following Guanfacine ingestion.

Postpartum Bilateral Subdural Hematomas: A Case Report.

Postpartum headache is a common emergency department (ED) complaint in women following delivery. Though the majority of these headaches are due to primary headache disorders or postdural puncture headaches, life-threatening complications can occur. Both postpartum pre-eclampsia can occur as well as hypercoagulable and vascular disorders including stroke, venous sinus thrombosis (VST), and reversible cerebral vasoconstrictive syndrome. With the increasing use of epidurals for intrapartum analgesia, rare, dangerous complications can present in a similar fashion. The authors present a persistent postpartum headache secondary to bilateral subdural hematomas (SDH) from epidural induced intracranial hypotension.

Pediatric Cirrhotic Variceal Bleed Precipitating Diabetic Ketoacidosis.

Cirrhosis and its associated complications such, as variceal bleeding, are rare in children, carrying significant morbidity and mortality. Leading causes of cirrhosis in the pediatric population include infection, neoplasm, and metabolic and genetic disorders, which is in contrast to the adult population. Acute gastrointestinal bleeding, as seen with variceal bleeding, has been previously associated with diabetic ketoacidosis through a multifactorial relationship. The case was complicated by hypovolemic shock whose resuscitation and subsequent transfusion was associated with cardiac overload. We highlight the need for balanced, judicious resuscitation in these individuals as well as the need for heightened awareness of coexisting pathologies such as diabetic ketoacidosis.

A Tale From the Early Stone Age: Pediatric Ureterolithiasis as Appendicitis Mimic - A Case Report and Management Overview.

Ureterolithiasis in the pediatric population is uncommon and may mimic acute abdomen. While the majority of small stones pass spontaneously, complications may ultimately warrant surgical intervention. As the majority of affected patients have a predisposing condition, targeted therapy with close and consistent follow-up may prevent recurrence, emphasizing timely diagnosis. The authors present the case of a previously healthy 13-year-old boy with eight days of right lower quadrant abdominal pain and emesis, who was found to have a distal ureteral stone necessitating surgical intervention.

Seizure-Associated Takotsubo Cardiomyopathy.

Takotsubo cardiomyopathy (TCOM) is a syndrome characterized by acute systolic dysfunction that can mimic acute coronary syndrome (ACS), usually incited by physical or emotional stress. However, acute neurological dysfunction, including seizures, has been recently described as an additional risk factor for the development of TCOM. This specific case report reviews the pathophysiology of TCOM and its management. We emphasize that providers should maintain a high index of suspicion for TCOM after acute neurologic dysfunction in patients with chest pain or hemodynamic instability, while also initiating proper investigation for ACS. Although classically thought of as a transient process, recent data show that both in-hospital and post-hospital morbidity and mortality related to this condition remain concerning.

Hide and Seek: Intermittent Preexcitation Wolff-Parkinson-White Syndrome Case Report and Management Overview.

Wolff-Parkinson-White (WPW) syndrome is an uncommon form of cardiac preexcitation due to an underlying structural accessory pathway, which may lead to potentially lethal arrhythmias. Classic electrocardiogram (ECG) findings of WPW include short PR interval, slurred upstroke of the QRS complex, and prolonged QRS duration. However, in intermittent preexcitation, a rare variant in contrast to continuous preexcitation, these findings are not always present, thus masking a diagnosis of WPW syndrome. Consequently, this may adversely affect or delay the appropriate treatment of short-term tachyarrhythmias and long-term definitive therapies for this syndrome. The emergency physician should promptly obtain an ECG after the termination of any tachyarrhythmia, and maintain a high index of suspicion for intermittent preexcitation with typical WPW ECG findings which were not present on prior studies. The authors present a case of a 17-year-old female diagnosed with an intermittent preexcitation variant of WPW syndrome after a case of successfully treated symptomatic supraventricular tachycardia (SVT).

A Hard Case to Swallow: Crucifix Esophageal Foreign Body in a Nonverbal Patient.

Delayed presentation of esophageal foreign bodies places patients at high risk for esophageal perforation and infection. In nonverbal patients as well as children and adults with other concomitant illnesses, it is important to consider a broad differential diagnosis for presentations with upper respiratory complaints. The authors present a case of a nonverbal, elderly woman who presented after several days of mild, dry cough and was ultimately found to have a large esophageal foreign body that had been present for an unclear amount of time.

An Atypical Presentation of Spontaneous Coronary Artery Dissection.

Spontaneous coronary artery dissection is a rare form of acute coronary syndrome (ACS) resulting from tears in the coronary vessel lumen leading to myocardial ischemia. Historically, younger to middle-aged Caucasian females without traditional risk factors for ACS are most commonly affected. The authors present the case of an African American female with numerous traditional ACS risk factors who presented to the emergency department with chest pain. Her workup revealed a stable electrocardiogram despite multiple sets of serially elevating cardiac enzymes and the patient was ultimately diagnosed with a spontaneous coronary artery dissection.

Native Mitral Valve Infective Endocarditis From Flossing: A Case Report and Emergency Department Management.

Infective endocarditis (IE) is a rare, elusive disease, carrying a 10%-30% mortality. Requiring a high index of suspicion, IE affects damaged native valves and prosthetic valves. While there are a number of inherent risk factors that predispose patients to IE, dental work in the preceding six weeks is often a culprit of disease, colonizing damaged native mitral valves with Streptococcus viridans species. Traditionally, flossing has been suggested to be protective against IE. We present a case of S. gordonii subacute IE on a regurgitant native mitral valve secondary to vigorous flossing.

Subdural Empyema in an Immunocompetent Active Duty Soldier: A Case Report.

Intracranial subdural empyema is a rare clinical entity with incidence estimates of 0.1 per 100,000 people. The condition is most often the sequela of a primary infection elsewhere and carries a high morbidity and mortality. The authors present the case of a 22-year-old active duty soldier on mission on the southern border of the United States. The patient had been complaining of headaches that became progressively worse over 2 weeks and presented to a civilian hospital where he was diagnosed with intracranial abscess versus sinus thrombosis on radiographic imaging. The patient was promptly transferred to a military tertiary care center where further workup including pivotal imaging confirmed subdural empyema and right transverse sinus thrombosis. Given the rapid patient deterioration associated with subdural empyema, the emergent intravenous antibiotics, neurosurgical consultation, and subsequent collection evacuation performed are likely to credit for saving this soldier's life. This case highlighted an atypical and time-sensitive etiology for a common complaint in the active duty population, which underscores the requirement for evacuation to higher roles of care in those soldiers with a similar diagnosis.

Adult Small Bowel Intussusception and Resolution Captured on Pelvic Ultrasound.

While abdominal pain is one of the leading causes for ED visits, intestinal intussusception is an infrequent etiology in adults. We present the case of a 22-year-old woman with five days of left lower quadrant abdominal pain with initial workup investigating for a genitourinary source utilizing pelvic ultrasound which revealed small bowel-small bowel intussusception. During the study, resolution of the intussusception correlated temporally with the patient's symptoms. Transient small bowel intussusception in adults has been previously described; however, direct visualization of both the intussusception and its resolution on pelvic ultrasound has not been previously published.

Pulsatile Mass: Ruptured Common Femoral Artery Pseudoaneurysm with Active Extravasation.

Delayed rupture of a pseudoaneurysm represents an extremely rare and life-threatening complication of endovascular, radiographic, and cardiac procedures. We discuss a case of a 69-year-old man with delayed rupture of a known left common femoral artery pseudoaneurysm, highlighting the importance of rapid recognition, to include the use of point of care ultrasound, if available. Computed tomographic angiography allows for better anatomic characterization and aids in operative planning, which is the mainstay of treatment. However, surgical repair in ruptured pseudoaneurysms remains a high-risk procedure.

Cardiac Tamponade in an 18-year-old Male with Undiagnosed Systemic Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is a multisystem, autoimmune condition of extremely variable presentation and prognosis. While pericardial effusion is a common disease sequela, subsequent tamponade is a rare, potentially fatal complication. We present the case of an 18-year-old, previously healthy male who presented to the emergency department with a chief complaint of abdominal pain and hematochezia. Workup revealed massive pericardial effusion with tamponade pathophysiology requiring emergent pericardiocentesis, with further workup confirming a diagnosis of SLE. While SLE often presents in an indolent manner, cardiac tamponade may be the initial presentation of this disease.

Necrotic Fibroid Mimicking Ovarian Torsion in a Second Trimester of Pregnancy.

Uterine fibroids are incredibly common, benign smooth muscle tumors which range in severity of symptoms from asymptomatic to debilitating. While pain is frequently a symptom, degeneration and necrosis of uterine fibroids can rarely present as acute abdomen. The authors present the case of a pregnant female at 19 weeks' gestation, whose clinical and radiographic presentation mimicked that of ovarian torsion, ultimately requiring exploratory laparoscopy for definitive diagnosis.

Reduce torques and stick the landing: limb posture during landing in toads.

A controlled landing, where an animal does not crash or topple, requires enough stability to allow muscles to effectively dissipate mechanical energy. Toads (Rhinella marina) are exemplary models for understanding the mechanics and motor control of landing given their ability to land consistently during bouts of continuous hopping. Previous studies in anurans have shown that ground reaction forces (GRFs) during landing are significantly higher compared with takeoff and can potentially impart large torques about the center of mass (COM), destabilizing the body at impact. We predict that in order to minimize such torques, toads will align their COM with the GRF vector during the aerial phase in anticipation of impact. We combined high-speed videography and force-plate ergometry to quantify torques at the COM and relate the magnitude of torques to limb posture at impact. We show that modulation of hindlimb posture can shift the position of the COM by about 20% of snout-vent length. Rapid hindlimb flexion during the aerial phase of a hop moved the COM anteriorly and reduced torque by aligning the COM with the GRF vector. We found that the addition of extrinsic loads did not significantly alter landing behavior but did change the torques experienced at impact. We conclude that anticipatory hindlimb flexion during the aerial phase of a hop is a critical feature of a mechanically stable landing that allows toads to quickly string together multiple, continuous hops.
