Enterovirus-Human-Rhinovirus Infection Leading to Acute Respiratory Distress Syndrome: A Case Report.

Enterovirus-human-rhinovirus (EV-HRV) is best known to cause the "common cold" and asthma exacerbations. Simple bronchitis and community-acquired pneumonia related to EV-HRV are also well documented. Scattered reports of rhinovirus causing acute respiratory distress syndrome (ARDS) have been published, yet the causality between recent SARS-CoV-2 pneumonia and severe ARDS secondary to EV-HRV has not been well defined. This case presents a 67-year-old male who was unvaccinated against SARS-CoV-2 with a past medical history of chronic obstructive pulmonary disease, who recently experienced a mild-to-moderate case of SARS-CoV-2 pneumonia, which was treated with dexamethasone and remdesivir. He was discharged to an inpatient psychiatric facility on as-needed oxygen via nasal cannula. Three weeks later, he experienced an episode of presyncope and was readmitted to the hospital. He then began to require increasing levels of supplemental oxygen via a high-flow nasal cannula. A real-time polymerase chain reaction respiratory pathogen panel was positive for EV-HRV. Computed tomography of the chest revealed extensive ground-glass opacities. Further workup for bacterial and fungal pneumonia was negative. Repeat SARS-CoV-2 testing was also negative. He required several days of supplemental oxygen via a high-flow nasal cannula. He received a short course of broad-spectrum antibiotics and a 10-day course of high-dose dexamethasone. Ultimately, he fully recovered, did not require further supplemental oxygen, and was discharged on room air.

Type A Aortic Dissection Presenting as Acute Coronary Syndrome in a Young Male Patient: A Case Report.

Type A aortic dissection (AD) is a devastating cardiovascular emergency requiring emergent surgical intervention. Most patients with AD have several risk factors for the disease including longstanding hypertension, smoking history, atherosclerosis, and old age. Younger patients may also present with AD if a genetic disorder affecting the integrity of the aorta is present. This case presents an otherwise healthy 36-year-old male with no known significant family history who presented with an atypical presentation of aortic dissection. He described a five-day history of chest pressure made worse with exertion followed by progressive dyspnea which prompted him to seek medical attention. His initial laboratory workup revealed an elevated troponin I level which prompted a cardiology consultation in the emergency department. Transthoracic echocardiography revealed dilatation of the aortic root and aortic regurgitation. CT angiography of the chest was performed revealing a type A dissection beginning at the aortic root and terminating proximal to the right brachiocephalic artery. Involvement of the coronary arteries was suspected due to the elevated troponin I. He was taken to the operating room and underwent aortic grafting, right coronary artery bypass, and repair of the left main artery. Unfortunately, at the end of the operation, the patient went into refractory ventricular fibrillation, which progressed to asystole. He was unable to be revived.

Liver Abscess Formation After Laparoscopic Radiofrequency Ablation of Metastatic Colon Cancer.

Radiofrequency ablation (RFA) may be used to treat either benign or malignant tumors of the liver. Complications are relatively rare, with the most common being pyogenic liver abscess formation. Risk factors for pyogenic liver abscess formation include Child-Pugh class B or C cirrhosis, biliary tract disease, diabetes mellitus, and preexisting biliary diversion. Differentiating sterile post-ablative necrosis from abscess formation may be difficult on imaging as air may be considered a normal post-ablation finding. Treatment of pyogenic liver abscesses includes drainage and antibiotics targeting the most common organisms. This case presents a 71-year-old female with none of the above risk factors who developed a pyogenic liver abscess after undergoing RFA for a solitary liver metastasis secondary to biopsy-proven colonic adenocarcinoma. She was successfully treated with antibiotics and an indwelling percutaneous drain.

Functional Neurological Symptom Disorder (FND) Leading to the Development of Deep Vein Thrombosis (DVT).

Functional neurological symptom disorder (FND) remains a clinical challenge. It is one of the many mimics of cerebrovascular accidents, spinal cord disorders, and lower motor neuron disease. Patients often undergo an extensive workup to exclude other causes of neurological dysfunction before the diagnosis is made. FND is often associated with weakness and paralysis, yet we could not locate a case depicting symptoms severe enough to cause venous thromboembolism. We present a patient diagnosed with FND who subsequently developed deep vein thromboses (DVT) of the bilateral lower extremities. She was placed on systemic anticoagulation and her functional symptoms improved with physical therapy (PT). This case describes the need for early PT to improve function and prevent complications related to functional immobility.

Small Bowel Perforation Secondary to Portal Vein Thrombosis.

Portal vein thrombosis (PVT) is a heterogeneous entity often described as either an acute or chronic occlusion of the portal vein or its tributaries. The clinical presentation is highly variable, and it often mimics other more common causes of abdominal pain. In most patients, imaging studies such as doppler ultrasound, computed tomography, or magnetic resonance imaging are adequate for diagnosis. Occasionally imaging studies may be inadequate, and the diagnosis may not be made until complications such as bowel necrosis and perforation have occurred. We present a case of a morbidly obese 45-year-old female who was initially treated for suspected small bowel enteritis and discharged home on several occasions after nonspecific findings on abdominal imaging were seen and interval improvement in symptoms occurred with intravenous fluids and antibiotics. She then presented with worsening symptoms and was found on abdominal imaging to have a large fluid collection in the peritoneal cavity requiring exploratory laparotomy with peritoneal washout and partial small bowel resection due to perforation. She was diagnosed with PVT with mesenteric extension after samples of the resected mesentery were evaluated in the pathology laboratory. Her treatment included a prolonged course of antibiotics, total parenteral nutrition, and anticoagulation.

Odontogenic Infection Complicated by Cervicofacial Necrotizing Fasciitis in a Healthy Young Female.

Necrotizing fasciitis (NF) is a critical and rapidly progressive infection of the skin and soft tissue, and it is associated with a high mortality rate. NF of the cervicofacial region is uncommon due to the rich vascular supply of the head and neck, which promotes an efficient immune response to infection. Patients who are immunocompromised or have comorbidities affecting the vasculature, such as diabetes mellitus or peripheral vascular disease, are at an increased risk of more severe disease and outcome. Cervicofacial necrotizing fasciitis (CNF) is most frequently attributed to mucosal damage, such as those related to dental infections or local trauma including medical procedures. Due to its ability to quickly spread to the neck and mediastinum, CNF must be diagnosed and treated expeditiously. In this report, we present a case of a 28-year-old female with a past medical history significant for obesity and tobacco abuse who presented to the emergency department (ED) with fever, left-sided facial pain, cervical pain, and swelling. She had worsening symptoms despite current treatment with clindamycin for a dental abscess. A CT scan of the head and neck revealed an odontogenic abscess complicated by CNF. Intravenous antibiotics were initiated and she underwent prompt surgical intervention. She remained nasally intubated following her surgery due to concern for postoperative edema leading to airway compromise. Following extubation, she experienced an uncomplicated recovery. This case demonstrates that NF is a complication of dental infection that may occur even in young and relatively healthy patients. Additionally, due to the swiftly destructive nature and high mortality rate of CNF, early diagnosis and aggressive medical and surgical therapy are essential to reduce morbidity and mortality.
