A Case of Bilateral Infected Kidney Stones Presenting With Septic Shock and Acute Kidney Injury.

The incidence of unilateral ureteral calculi has been reported at 20% in the literature; however, cases of bilateral kidney stones are not commonly reported in the urology, nephrology, and emergency medicine literature. Here, we present the case of a 31-year-old female who presented to the emergency department with septic shock and acute kidney injury. Acute kidney injury was initially thought to be prerenal secondary to septic shock but later found to have complete bilateral ureteral obstruction as a cause of septic shock and acute kidney injury. Urinary tract infection and sepsis secondary to bilateral obstructing ureteral stones are some of the few true urological emergencies. Anuria is the common presenting feature of complete urinary tract obstruction, and physicians should have a high index of suspicion for this diagnosis in anuric patients as rare as it is.

A Case of E-cigarette or Vaping Product Use-Associated Lung Injury Mimicking Miliary Tuberculosis.

E-cigarette usage or vaping is becoming more popular as an alternative option to cigarette smoking. Vaping is associated with a wide degree of pulmonary injuries such as asthma, chronic obstructive pulmonary disease or E-cigarette or vaping product use-associated lung injury (EVALI). E-cigarette or vaping product use-associated lung injury is an acute or subacute respiratory illness that can be severe and life-threatening. Miliary tuberculosis, on the other hand, is a rare form of tuberculosis that results from hematogenous dissemination of Mycobacterium tuberculosis, affecting multiple organs and systems. It is characterized by the presence of small, firm white nodules resembling millet seeds. We report a case of a young patient presenting to the hospital with features suggestive of miliary tuberculosis in the CT scan of the chest. Diagnosis of EVALI was reached after extensive diagnostic workup including tuberculosis revealed negative.

Midterm outcomes and durability of sinus segment preservation compared with root replacement for acute type A aortic dissection.

OBJECTIVE: The durability of root repair for acute type A aortic dissection is not well studied in the context of aortic insufficiency and stability of the sinuses of Valsalva. We compared clinical and functional outcomes in patients undergoing root repair and replacement for acute type A aortic dissection. METHODS: Of 716 patients undergoing surgery for acute type A aortic dissection, 585 (81.7%) underwent root repair and 131 (18.3%) underwent root replacement. Survival, cumulative incidence of reoperation, aortic insufficiency, and sinuses of Valsalva dilation were compared between the 2 groups. RESULTS: Survival at 1, 5, and 10 years was 84.1% versus 77.3%, 70.8% versus 69.2%, 57.6% versus 58.0% in the root repair and replacement groups, respectively (P = .69). Cumulative incidence of reoperation at 1, 5, and 10 years was 0.0% versus 0.8%, 1.4% versus 3.8%, and 3.4% versus 8.6% in the root repair and root replacement groups, respectively (P = .011). Multivariable Cox regression identified sinuses of Valsalva diameter 45 mm or more as a risk factor for proximal aortic reoperation (hazard ratio, 9.06; 95% confidence interval, 1.26-65.24). In a repeated-measures, linear, mixed-effects model, root replacement was associated with smaller follow-up of sinuses of Valsalva dimensions (ß = -0.66, P < .001). In an ordinal longitudinal mixed model, root replacement was associated with lower severity of postoperative aortic insufficiency (ß = -3.10, P < .001). CONCLUSIONS: Survival is similar, but the incidence of aortic insufficiency and root dilation may be greater after root repair compared with root replacement for acute type A aortic dissection.

Midterm outcomes of emergency surgery for acute type A aortic dissection in octogenarians.

OBJECTIVE: The incidence of elderly patients with acute type A aortic dissection is increasing. A recent analysis of the International Registry of Acute Aortic Dissection failed to show a mortality benefit with surgery compared with medical management in octogenarians. Therefore, we compared our institutional outcomes of emergency surgery for acute type A aortic dissection in octogenarians versus septuagenarians to understand the outcomes of surgical intervention in elderly patients. METHODS: From 2002 to 2017, 70 octogenarians (aged ≥80 years) and 165 septuagenarians (70-79 years) underwent surgery for acute type A aortic dissection (N = 235, total). Quality of life was assessed by the RAND Short Form-36 quality of life survey. Midterm clinical and functional data were obtained retrospectively. RESULTS: At baseline, septuagenarians had a higher prevalence of diabetes (20.6% vs 5.7%, P = .01). The prevalence of cardiopulmonary resuscitation was 4.8% versus 10.0% (P = .24) in septuagenarians and octogenarians. The prevalence of cardiogenic shock was 18.2% versus 27.1% (P = .17). Thirty-day/in-hospital mortality was 21.2% versus 28.6% (P = .29). Multivariable logistic regression identified cardiogenic shock as an independent risk factor for in-hospital mortality (odds ratio, 10.07; 95% confidence interval, 2.30-44.03) in octogenarians. Survival at 5 years was 49.7% (42.1%-58.6%) versus 34.2% (23.9%-48.8%) in septuagenarians and octogenarians, respectively. Responses to the quality of life survey were no different between septuagenarians and octogenarians across all 8 quality of life categories. CONCLUSIONS: Clinical outcomes after surgery for acute type A aortic dissection are similar in octogenarians and septuagenarians. For discharged survivors, quality of life remains favorable and does not differ between the 2 groups.

Long-term outcomes of aortic root procedures for heterogenous ascending aneurysm disease in bicuspid aortic valve syndrome.

OBJECTIVE: Surgery for ascending aneurysms in bicuspid aortic valve syndrome primarily includes Bentall root replacement, aortic valve replacement with supracoronary ascending aorta replacement (AVRSCAAR), and valve-sparing root reimplantation (VSRR). Comparative analysis of long-term clinical and functional outcomes of these procedures is detailed. METHODS: From 1997 to 2017, 635 patients with bicuspid aortic valve undergoing root complex-focused procedures electively were stratified by valvulopathy (ie, aortic stenosis vs aortic insufficiency) and substratified into ascending or root aneurysm phenotype. Inverse probability weights were calculated to adjust for baseline differences. RESULTS: Kaplan-Meier curves for all-cause mortality demonstrated no difference between Bentall versus AVRSCAAR for aortic stenosis and aortic insufficiency presentations (log-rank P > .05). In patients with aortic stenosis, multivariable Cox regression showed significantly decreased risk of stroke for biologic AVRSCAAR (hazard ratio, 0.04; P = .013). Aortic reoperation rates were similar for biologic versus mechanical valves (P = .353). In patients with aortic insufficiency, similar long-term mortality (hazard ratio, 0.95; P = .93), but lower stroke risk in biologic AVRSCAAR group by Cox regression, and lower aortic reoperation rate was noted (coefficient < 0.01; P < .001). Comparing Bentall to VSRR, mortality (hazard ratio, 0.12; P = .022) was significantly improved in patients undergoing VSRR, but recurrence of moderate or greater aortic insufficiency was higher in VSRR by multistate model (beta coefficient 2.63; P < .001). CONCLUSIONS: A tailored approach to heterogeneous ascending aneurysm pathologies in bicuspid aortic valve syndrome utilizing Bentall, AVRSCAAR, and VSRR procedures renders excellent long-term clinical and functional outcomes, with biologic conduits showing equivalent to improved clinical outcomes.

Non-typhoidal, Non-paratyphoidal Salmonella Species Causing Sacroiliitis and Pyomyositis in a Healthy 19-Year-Old Athlete.

Salmonella is a gram-negative bacterium, subdivided into typhoidal and non-typhoidal Salmonella. It is usually caused by eating raw or undercooked meat, poultry, eggs, or egg products. The clinical manifestations of Salmonella infection can be divided into five syndromes: enterocolitis (food poisoning), enteric (typhoid) fever, bacteremia/septicemia, focal infection, and a chronic carrier state, which is usually asymptomatic. The most common clinical presentation is diarrhea. Salmonella osteomyelitis occurs most frequently in patients with sickle-cell disease; other risk factors include other hemoglobinopathies, immunocompromised status, and chronic Salmonella carrier state. The incidence of Salmonella osteomyelitis/septic arthritis in otherwise healthy individuals is rare. The duration of symptoms can range from a few months to several years, and multifocal involvement occurs in 15% of reported cases of Salmonella osteomyelitis. The symptoms of Salmonella osteomyelitis are pain and variable swelling of the affected limb; high temperatures are rarely noted. Our patient is a 19-year-old boy with no known past medical history who presented with severe right-sided sacroiliitis with extensive surrounding osteomyelitis on both sides of the sacroiliac joint with non-typhoidal, non-paratyphoidal Salmonella bacteremia.

Diagnostic Challenges of Pneumocystis Pneumonia during the COVID-19 Pandemic: A Case of a Young Patient with Ground Glass Opacities and Pulmonary Embolism on Chest CT.

The coronavirus disease 2019 (COVID-19) pandemic is wreaking havoc across the globe. This pandemic has given rise to a mindset where physicians tend to neglect other causes of pneumonia, especially if the patient presents with signs and symptoms commonly associated with COVID-19. Herein, we report a case of a young man presenting to the emergency department with common clinical, radiological, and laboratory features of COVID-19 pneumonia such as shortness of breath, hypoxia, pulmonary embolism, elevated D-dimer, and bilateral ground glass opacities on computed tomography of the chest but was later diagnosed with Pneumocystis pneumonia that was treated with appropriate antibiotics and corticosteroids. This case highlights the importance of performing a thorough clinical history and differentiating the clinical and radiological features of COVID-19 pneumonia from pneumonia of other etiologies.

Unilateral pulmonary edema in acute aortic regurgitation: A complication of infective endocarditis.

Cardiogenic unilateral pulmonary edema (UPE) is an uncommon clinical entity and it represents just 2% of cardiogenic pulmonary edema with inclination for the right upper lobe and it is most commonly associated with severe mitral regurgitation. In our review, the literature does not include any UPE cases that are associated with severe aortic regurgitation (AR). Herein, we present a case with UPE, that includes a patient diagnosed with infective endocarditis who presented with shortness of breath. Initial chest imaging revealed UPE. Severe acute AR was diagnosed clinically and confirmed by echocardiogram, caused by vegetations on the non-coronary cusp of the aortic valve. The patient was transferred for emergent surgical intervention. This case underscores the importance of emergently evaluating valvular pathology to reduce the mortality rate that is associated with this condition. .

A Case of Three-Vessel Coronary Artery Disease Associated With Marijuana Use.

Marijuana is one of the most popular psychotropic drugs among adolescents and young adults. With the recent surge in marijuana use across the United States, it is very important for physicians to understand the clinical implications associated with marijuana use. In this case report, we discuss a case of a young adult who presented to the emergency department with chest pain and was found to have three-vessel coronary artery disease (CAD). The patient did not have any significant past medical history or family history of cardiac diseases but reported a significant history of marijuana use. This case report aims to add to the growing area of research on the association between myocardial infarction (MI) and marijuana use.

Recurrent aortic insufficiency after emergency surgery for acute type A aortic dissection with aortic root preservation.

OBJECTIVE: Patients with acute type A aortic dissection demonstrate a wide range of aortic insufficiency. Outcomes after valve resuspension and root repair are not well studied in the long term. We evaluated the long-term effects of preoperative aortic insufficiency in patients undergoing emergency root-preserving surgery for acute type A aortic dissection. METHODS: From 2002 to 2017, 558 of 776 patients with acute type A aortic dissection underwent native aortic valve resuspension and root reconstruction. Patients were stratified into 4 groups by preoperative aortic insufficiency grade (n = 539): aortic insufficiency less than 2+ (n = 348), aortic insufficiency = 2+ (n = 72), aortic insufficiency = 3+ (n = 49), and aortic insufficiency = 4+ (n = 70). Multivariable ordinal longitudinal mixed effects and multi-state transition models were used to assess risk factors for recurrent aortic insufficiency. RESULTS: The prevalence of cardiogenic shock in patients presenting with preoperative aortic insufficiency less than 2+, 2+, 3+, and 4+ was 53 of 348 (15.2%), 12 of 72 (16.7%), 10 of 49 (20.4%), and 24 of 70 (34.3%), respectively (P = .002). Postoperatively, 94.0% of patients had aortic insufficiency 1+ or less at discharge. Operative mortality was 34 of 348 (9.8%), 10 of 72 (13.9%), 6 of 49 (12.2%), and 12 of 70 (17.1%) (P = .303). In an ordinal mixed effects model, preoperative aortic insufficiency was associated with more severe postoperative aortic insufficiency. The multi-state transition model demonstrated that severe aortic insufficiency was associated with progression from no to mild aortic insufficiency (hazard ratio, 2.14; 95% confidence interval, 1.35-3.38), and progression from mild to moderate aortic insufficiency (hazard ratio, 5.70; 95% confidence interval, 1.88-17.30). CONCLUSIONS: Preoperative aortic insufficiency is an important predictor of recurrent aortic insufficiency in patients undergoing valve resuspension with root reconstruction for emergency acute type A aortic dissection repair. Increased echocardiographic surveillance for recurrent aortic insufficiency may be warranted in this cohort.

Rare but Fatal Case of Cavitary Pneumonia Caused by Alcaligenes Faecalis.

Alcaligenes faecalis is a gram-negative bacterium that is commonly found in the environment. This pathogen is usually transmitted in the form of droplets through ventilation equipment and nebulizers, but transmission through direct contact has also been documented in few case reports. This pathogen can cause rare but fatal infections including appendicitis, abscesses, meningitis, bloodstream infection, endocarditis, and post-operative endophthalmitis. Pan drug resistance to all commercially available antibiotics has been emerging globally. We present the case of a 66-year-old male who had respiratory failure along with multiple comorbidities. A large cavitary lesion caused by pan drug-resistant Alcaligenes faecalis was found on chest imaging. Despite the treatment with broad-spectrum antibiotics, the clinical outcome was very poor.

Severe Pulmonary Hypertension and Cholestatic Liver Injury: Two Rare Manifestations of Graves' Disease.

Graves' disease is seen in the majority of patients diagnosed with hyperthyroidism. The usual symptoms of Graves' disease are tremors, weight loss, sweating, exophthalmos, pretibial edema, anxiety, and palpitations. However, there could be unusual manifestations such as hepatic failure and pulmonary hypertension. We present the case of a 31-year-old female with Graves' disease with these two rare complications, which resolved with medical management in about three months. To the author's knowledge, this is the second case of a patient with this type of presentation.

Diagnosis and Management of 1:1 Atrial Flutter in the Setting of Aortic Valve Endocarditis and Embolic Stroke.

Atrial flutter is a rapid, regular atrial tachyarrhythmia that occurs most commonly in patients with underlying structural heart disease. Spontaneous 1:1 conduction of atrial flutter is indeed rare, but its diagnosis and management is of critical importance. We describe a case of a 65-year-old man with hypertension, preserved ejection fraction heart failure, end-stage renal disease, Parkinson's disease, and Alzheimer's dementia, in whom atrial flutter was associated with 1:1 atrioventricular conduction. Our patient was hemodynamically unstable with aortic valve endocarditis and recent septic embolic stroke. This case report emphasizes the importance of recognition and management to avoid hemodynamic compromise.

Fate of the Preserved Sinuses of Valsalva After Emergency Repair for Acute Type A Aortic Dissection.

BACKGROUND: Patients with acute type A aortic dissection (ATAAD) present with heterogeneous involvement of the aortic root complex. Despite this variation, the aortic root can usually be preserved the majority of the time by Teflon (WL Gore, Newark, DE) inlay patch reconstruction of the dissected sinuses of Valsalva (SOV). In this study, we report the long term anatomic, functional, and clinical outcomes associated with the preserved SOV after surgery for ATAAD. METHODS: From 2002-2017, of 776 emergency ATAAD operations at a single institution, 558 (71.9%) underwent valve resuspension with SOV preservation. Echocardiography reports were reviewed to obtain postoperative SOV dimensions. Cumulative incidence of SOV dilation ≥ 4 5mm was calculated using the Fine-Gray method with death as a competing risk. Repeated-measures linear mixed effects model was used to determine risk factors for SOV growth over time. RESULTS: During the follow-up period, 62 of 558 (11.1%) patients developed SOV diameter ≥ 45 mm. Cumulative incidence of SOV dilation ≥ 45 mm at 1, 5, and 10 years was 5.5%, 12.4%, and 18.9% respectively. In a multivariable Cox regression model, preoperative SOV diameter ≥ 45 mm was associated with a hazard ratio of 14.11 (95% confidence interval 7.03-31.62) for postoperative SOV dilation ≥ 45 mm. In a repeated-measures linear mixed effects model, preoperative and discharge SOV diameter were significant predictors of SOV dilation. Postoperative time course was also identified as significant indicating growth over time. CONCLUSIONS: The preserved sinuses of Valsalva after surgery for ATAAD may be prone to progressive dilatation over time. Closer echocardiographic surveillance may be warranted in these patients.
