Subglottic Stenosis as a Presentation of Antineutrophil Cytoplasmic Antibody-Associated Glomerulonephritis.

Granulomatosis with polyangiitis (GPA), previously Wegener's granulomatosis, is a necrotizing vasculitic disease process affecting the small- and medium-sized blood vessels. GPA is frequently associated with damage to the respiratory tract and kidneys but often affects other organ systems including the eyes, nasopharynx, and nervous system. Due to the vague nature of presenting symptoms and the progressive nature of GPA, it is essential to keep a broad differential to mitigate the high morbidity and mortality associated with the disease. Here we introduce a case of a GPA presenting as respiratory distress, stridor, and renal injury. We also review common clinical presentations, diagnostic evaluation, and treatment options.

Severe Coronary Artery Ectasia in a 31-Year-Old Presenting With an Inferior ST-Elevation Myocardial Infarction: A Case Report.

Coronary artery ectasia (CAE) is a rare dilation of the lumen in coronary arteries, either localized to one vessel or diffuse in multiple vessels. A 31-year-old white male with no significant past medical or cardiac history, presented with severe sudden onset chest pain, diaphoresis, shortness of breath, and nausea without vomiting. A 12 lead electrocardiogram (EKG) showed an ST elevation in the inferior leads with reciprocal changes, suggestive of myocardial infarction in the right coronary artery (RCA). He was taken directly to the catheterization laboratory for coronary angiography, which identified a mid-RCA thrombus with thrombolysis in myocardial infarction (TIMI)-1 flow, and distal to that in the right posterolateral branch was another thrombus with TIMI-0 flow. Additionally, he was found to have severely diffuse CAE in all of his coronary arteries. Angioplasty successfully restored TIMI-3 flow throughout the RCA. We present this case to discuss the prevention of complications from CAE. There are currently no recommendations on the use of antiplatelet or anticoagulation therapy in patients with CAE.

Case of multi-drug resistant Nocardia nova as the causative agent of cervical spine osteomyelitis in an immunocompetent adult.

We report a case of a 54-year-old immunocompetent female with cervical spine discitis and osteomyelitis secondary to Nocardia nova. Nocardia nova is overall an exceedingly rare cause of infectious diseases. In this case, the patient was admitted for neck and right shoulder pain. One year prior, she had lumbar osteomyelitis (L4-L5) that required laminectomy. Cultures at that time grew Staphylococcus schleiferi and she was treated with cefazolin for six weeks. Six months later she presented with cervical spine (C4-C5) discitis/osteomyelitis. She underwent surgical laminectomy, biopsy and culture, which grew Nocardia nova. The patient was treated with intravenous amikacin and then transitioned to trimethoprim-sulfamethoxazole for a total of twelve months. Other case reports of spinal osteomyelitis secondary to nocardia describe treatment with antibiotics, surgical debridement plus or minus arthrodesis with favorable outcome in improving pain and functionality at 3 years.1 In our case, the patient completed the course of antibiotics and 6 months later, imaging of the cervical spine showed mild height loss at C4 and C5, however no significant acute changes in the cervical spine, epidural or prevertebral soft tissue collections. She continues with chronic neck pain but repeated MRI of the cervical spine at 2 years shows no evidence of osteomyelitis or soft tissue edema.

A Retrospective Study of Admission NT-proBNP Levels as a Predictor of Readmission Rate, Length of Stay and Mortality.

Introduction: Serum levels of pro-B-type natriuretic peptide (BNP) and N-terminal (NT) proBNP are measured at admission to assess the likelihood of acutely decompensated heart failure (ADHF). Elevated NT-proBNP levels on initial presentation are a reliable marker of ADHF. However, the prognostic significance of NT-proBNP levels measured on admission remains unknown. With a better understanding of how admitting NT-proBNP levels impacts readmission rates, length of stay and mortality, future prospective studies with specific interventions can be developed to reduce all-cause readmissions, shorten length of stay and reduce mortality. Methods: In this retrospective study, we evaluated heart failure with reduced ejection fraction (HFrEF) admissions from 2017-2018 with a focus on 30-, 60- and 90-day all-cause readmissions, length of stay (LOS) and in-hospital mortality rate that are predicted by NT-proBNP levels measured on admission. Using the HCA Healthcare Enterprise Data Warehouse, adult patients age 18 to 75 were selected using admission ICD-10 codes for HFrEF. Dialysis patients were excluded. Our search of 90 hospitals yielded 21,445 patients who were stratified into quartiles depending on their admission NT-proBNP levels: group 1 (<1669 pg/ml), group 2 (1670-4274 pg/ml), group 3 (4275-10,499 pg/ml) and group 4 (>10,500 pg/ml). Results: Readmission Rates: The 60-day all-cause readmission was significantly (p = 0.047) higher in group 4 compared to group 1 (adjusted odds ratio (OR) = 1.116, p = 0.013) and group 2 (adjusted OR = 1.111, p = 0.014). The 90-day all cause readmission for group 4 was also significantly higher when compared to group 1 (adjusted OR = 1.105, p = 0.021).Length of Stay: Elevated NT-proBNP concentrations were associated with a significantly longer LOS (p <0.0005). Pairwise, comparisons and estimates for adjusted LOS showed a positive linear association between higher NT-proBNP groups and longer LOS.Mortality: Higher inpatient mortality rates were associated with elevated NT-proBNP levels. The mortality rate was 0.9% in group 1 compared to a 4.7% mortality rate in group 4. Adjusted OR for mortality increased with increasing levels of NT-proBNP. Conclusions: Based on the analysis, higher admitting NT-proBNP levels were associated with significantly higher 60-day all-cause readmission, longer LOS and increased mortality. These findings suggest that measuring NT-proBNP levels at admission may provide an indication of patient outcomes. Prospective studies with targeted strategies can be developed to reduce readmissions, shorten LOS and reduce mortality based on admission NT-proBNP levels.

Lupus Cerebritis as the Initial Presentation of Systemic Lupus Erythematosus in a Young Female.

The psychiatric and neurological symptoms of systemic lupus erythematosus (SLE) are referred to as lupus cerebritis. The wide range of symptoms associated with SLE can pose a diagnostic challenge. We present a case of lupus cerebritis in a 31-year-old female presenting with psychosis. We present this case to increase awareness of the psychiatric manifestations of SLE that can be mistaken for more common etiologies of psychosis.

Palliative ketamine: the use of ketamine in central post-stroke pain syndrome-a case report.

Ketamine has played a versatile role in medicine due to its wide spectrum of uses in history including use in sedation, catalepsy, somatic analgesia, bronchodilation, and recent trial in complex chronic pain syndromes. There is very little, if any, discussion in the literature of ketamine use in stroke, particularly in improving symptoms of pain after stroke. We present a case of a 40-year-old female with a past medical history of right-sided thalamic ischemic stroke complicated by Central post-stroke pain syndrome (CPSP) presented for refractory severe diffuse pain causing debility and immobility. The patient failed outpatient medical therapy consisting of anxiolytics, serotonin, and norepinephrine reuptake inhibitors. This led to increased opioid use which resulted in dependence and opioid-hyperalgesia. Upon admission, the patient was unable to sit still, with severe, sharp 10/10 pain localized to her left lower extremity. Palliative medicine was consulted for management of refractory central neuropathic pain. Inpatient oral ketamine was initiated, and titrated over the patient's hospital course. During this time, the patient showed marked improvement in GAD-7, PHQ-9, and Short Mcgill pain scores while significantly decreasing opioid requirements. We present this case to demonstrate how oral ketamine usage in centrally mediated neuropathic pain such as in CPSP can lead to pain control, decreased opioid usage, and overall improved quality of life.

Ischemic Nephropathy Following Occlusion of Abdominal Aortic Aneurysm Graft: A Case Report.

In this report, we present a case of a 55-year-old female with a past medical history of abdominal aortic aneurysm (AAA) graft, femoral-femoral bypass graft, questionable history of chronic kidney disease (CKD), abdominal hernia repair, alcoholic pancreatitis, chronic abdominal pain on opioids, and tobacco abuse who presented with acute on chronic abdominal pain with an unexplained rise of creatinine and anuria. The patient was found to have complete occlusion of AAA graft and was determined to have ischemic nephropathy (IN).

A Retrospective Review of Upper Gastrointestinal Bleed Outcomes During Hospital Admission While on Oral Anticoagulation.

Introduction Direct-acting oral anticoagulants (DOACs) are approved for stroke prevention in non-valvular atrial fibrillation and treatment of venous thromboembolism. Most recent guidelines recommend DOACs over warfarin for most diagnoses given their predictable pharmacodynamics, lack of required monitoring, and safety profile. Specific outcomes such as shock, acute renal failure, and blood transfusion requirement while on oral anticoagulation compared to no anticoagulation remain unknown in patients with upper gastrointestinal (GI) bleeds.  Methods This retrospective study used the HCA Healthcare Enterprise Data Warehouse (EDW) to analyze 13,440 patients aged >18 years that were admitted with an upper GI bleed from January 2017 to December 2019. The patients were categorized based on oral anticoagulant (i.e. rivaroxaban, apixaban, dabigatran and warfarin). The control group was patients admitted with an upper GI bleed not on oral anticoagulation. We evaluated the severity of upper GI bleeds while on oral anticoagulation based on the outcomes: mortality rate, length of stay, acute renal failure, shock, and need for packed red blood cell transfusions (pRBC). Comorbid conditions assessed were coronary artery disease (CAD), chronic obstructive pulmonary disease (COPD), heart failure (HF), atrial fibrillation (AF), venous thromboembolism (VTE), peripheral vascular disease (PVD), tobacco abuse, alcohol abuse, and chronic kidney disease (CKD). Home use of proton pump inhibitors (PPI), aspirin, and P2Y12 inhibitors were also evaluated.  Results Patients on a DOAC without home PPI have a mortality odds ratio of 3.066 with a confidence interval (CI) greater than 95% (1.48-6.26, p<0.05) compared to patients on a DOAC and home PPI. Patients on warfarin and no home PPI have a mortality odds ratio of 5.55 (95% CI (1.02-30.35), p<0.05) compared to those on warfarin with home PPI use. In the no anticoagulation group, those not on PPI have an odds ratio of 3.28 (95% CI (2.54-4.24), p<0.05) of death compared to home PPI use. There was no statistical difference in mortality between each DOAC and warfarin.  There was no difference in the presence of acute renal failure or shock when comparing each DOAC, warfarin, and no medication. For patients presenting with GI bleed, 0.8414 units of pRBC were transfused. Patients not on oral anticoagulation were found to have statistically significant decrease in pRBC transfusion if they did not report alcohol use, CKD, HF, AF, VTE, PVD. Patients on DOACs and alcohol use have an average pRBC transfusion count that is 0.922 units more than those without reported alcohol use (p=0.006). In the warfarin group, there was no statistical significance noted when comparing pRBC transfusions and also when comparing to baseline comorbidities. Conclusion The retrospective study leads us to conclude that overall, patients taking the DOACs or warfarin had no statistically significant increase in RBC transfusions, length of stay, shock, acute renal failure, or mortality rate compared to patients who were not on oral anticoagulation. Home PPI use was shown to lower odds of mortality in patients on anticoagulation who presented with upper GI bleeding. PPI use had no effect on the need for transfusion or length of stay in patients on anticoagulation. These results can help predict which patients are likely to have higher mortality based on the use of home PPIs.

A Retrospective Review of Outcomes in Intensive Care Unit Patients Infected With SARS-Cov2 in Correlation to Admission Acute Physiologic Assessment and Chronic Health Evaluation II Scores.

Introduction Coronavirus disease 2019 (COVID-19) has emerged as a global pandemic that has placed an unprecedented burden on intensive care services worldwide. Identification of a reliable risk-stratification tool for COVID-19 patients is necessary for appropriate resource allocation, selection of clinical management pathways, and guidance of goals of care conversations with families and caregivers in the critical care setting. The Acute Physiologic Assessment and Chronic Health Evaluation (APACHE) II scoring system is one of several predictive models used to classify illness severity and estimate mortality risk on admission to the intensive care unit (ICU). Our retrospective study sought to evaluate the prognostic ability of the APACHE II score in COVID-19 patients according to endpoints of mortality and length of stay (LOS) as well as unfavorable clinical outcomes, including development of acute renal failure (ARF) requiring renal replacement therapy (RRT) and acute venous thromboembolic events (VTE). Methods This multicenter retrospective cohort study evaluated a randomized sample of 3,102 patients with confirmed COVID-19 disease admitted to the ICU from January 2020 to May 2020. A total of 395 patients with complete data points for appropriate APACHE II score calculation, absence of the preexisting comorbidities end-stage renal disease, and history of VTE were included. Linear and logistic regression models were employed to evaluate primary outcomes of mortality and LOS as well as secondary outcomes of VTE and ARF requiring continuous renal replacement therapy (CRRT) or hemodialysis (HD). Key results Among the 395 patients enrolled, total percent mortality and mean LOS were 37.0% and 12.92 days, respectively. Primary outcome analysis revealed a statistically significant increase in odds of mortality as well as in mean LOS with every additional point increase in APACHE II score from a baseline of zero. Specifically, for every point increase in the APACHE II score, odds of mortality increased by 12% (p value < 0.001), and average LOS increased by 0.2 days (p value < 0.001). In our secondary outcome analysis, 14.43% and 62.2% of the total sample population developed ARF requiring RRT and VTE, respectively. For every additional point increase in APACHE II score from a baseline of zero, odds of requiring CRRT or HD increased by 10% on average (95% CI (1.06, 1.15); p value < 0.001). Similarly, for every additional point increase in the APACHE II score from a baseline of zero, there was a corresponding increase in odds of VTE by 19% (95% CI (1.14, 1.24); p value < 0.001). Conclusions The APACHE II score is an effective predictive model of in-hospital mortality and unfavorable clinical outcomes, including prolonged LOS, ARF requiring CRRT or HD, and development of VTE. As therapeutic interventions for COVID-19 evolve, application of this risk-stratification tool may guide clinical management decisions in the critical care setting.

Meropenem-Resistant Achromobacter xylosoxidans, Subspecies Denitrificans Bacteremia in a Patient With Stage IV Adenocarcinoma of the Lung.

Achromobacter xylosoxidans,subspecies denitrificans is a rare Gram-negative bacillus that causes health care associated infections in immunocompromised hosts. Carbapenems and anti-pseudomonal penicillins are listed as suitable empiric therapy in the literature. Herein, we report a case of a 77-year-old male with stage IV adenocarcinoma of the lung who presented with and was improving from Salmonella javiana enterocolitis, only to subsequently develop A. xylosoxidans,subspecies denitrificans bacteremia that was resistant to both meropenem and piperacillin-tazobactam. With empiric antibiotic coverage falling short of microbial clearance, timelyin vitrosusceptibility testing and prompt infectious disease consultation are of the utmost importance for treatment.

Immunotherapy-Induced Acute Tubulointerstitial Nephritis.

Due to its minimal side-effect profile, immunotherapy has become a popular choice for the treatment of advanced melanoma as compared to conventional chemotherapy. The most common side effects associated with immunotherapy include gastrointestinal, pulmonary, and dermatologic manifestations. However, there have been very few documented occurrences of nephrotoxic side effects. We present a case of a 73-year-old male with a past medical history of chronic kidney disease (CKD) stage 3A, metastatic uveal melanoma, and gastroesophageal reflux disease on pantoprazole who arrived at the intensive care unit with altered mental status and creatinine of 27 gm/dl (baseline creatinine of 3 gm/dl about one year prior), after receiving his first dose of ipilimumab and nivolumab approximately 21 days prior. Kidney biopsy demonstrated acute tubulointerstitial nephritis (ATIN). This case highlights the importance of recognizing acute tubulointerstitial nephritis as a side effect of immunotherapy for prompt diagnosis and early treatment.

Sarcoidosis presenting as massive splenomegaly and severe epistaxis, case report.

Sarcoidosis is a multisystem disorder of unknown etiology. Extrapulmonary sarcoidosis can involve any organ, but isolated spleen involvement is rare. Diagnosis can be challenging as other etiologies may have similar presentations. A 58-year-old African American female presented with life threatening epistaxis, anemia, refractory thrombocytopenia, and massive splenomegaly. Lymphoproliferative, infectious, and autoimmune etiologies were eliminated with laboratory testing and bone marrow biopsy. The patient had multiple splenic artery aneurysms precluding an open diagnostic splenectomy. Partial splenic artery embolization was performed, which normalized the platelet count and resolved the spontaneous bleeding. This allowed diagnostic splenectomy and splenic artery repair to be safely performed. Surgical pathology demonstrated extensive non-caseating granulomas consistent with sarcoidosis. We present this case to demonstrate the omnipotent nature of sarcoidosis and a complex multi-disciplinary approach for successful diagnosis and treatment.

Acute Plasma Cell Leukemia Presenting as Primary Hyperammonemic Encephalopathy.

Primary plasma cell leukemia (PPCL) is a rare form of multiple myeloma (MM) and is a rare aggressive disease with a median overall survival of 6 - 11 months. We present a case of acute hyperammonemic encephalopathy as the initial presentation of PPCL in a 78-year-old woman to highlight an atypical presentation of this disorder.

False-Negative CSF Cryptococcal Antigen with Cryptococcus gattii Meningoencephalitis in Southeastern United States: A Case Report and Literature Review.

A 70-year-old immunocompetent male in South Carolina was admitted secondary to altered mental status and headache without focal neurological deficits. Head CT was negative. Lumbar puncture (LP) revealed normal glucose, elevated protein, and lymphocytosis. Opening pressure was 15 cm of H20. CSF lateral flow assay was negative for cryptococcal antigen; CSF cultures showed no growth. The patient rapidly improved on acyclovir and was diagnosed with presumed viral meningitis, as viral PCR and fungal culture were pending at time of discharge. The patient's condition quickly worsened and the patient returned one day later with right arm weakness and dysarthria. Brain MRI revealed T2/flair signal abnormalities in the left frontal lobe with associated parenchymal enhancement. Repeat LP revealed increasing white blood cell count with a worsening lymphocytosis and decreasing glucose, and opening pressure remained normal. CSF fungal culture from the first admission grew Cryptococcus gattii, and repeated CSF cryptococcal antigen and culture returned positive. The patient was started on IV steroids, induction Amphotericin and Fluconazole, followed by maintenance oral Fluconazole. The patient's clinical course was complicated by a brainstem lacunar infarction, which led to demise. We present this case of Cryptococcus gattii meningoencephalitis to highlight the risk factors, characteristics, and challenges in diagnosis and treatment of an emerging disease in the Southeastern United States.

Metastatic Small-Cell Lung Cancer Presenting as Primary Adrenal Insufficiency.

A 40-year-old male smoker with HIV was admitted for cough, hypotension, and abdominal pain for 5 days. Chest radiography showed a right lower lobe consolidation. CT of the chest, abdomen, and pelvis revealed paratracheal adenopathy, a 5.8 × 4.5 cm mass invading the right bronchus intermedius, and dense bilateral adrenal masses, measuring 5.4 × 4.0 cm on the right and 4.8 × 2.0 cm on the left. Laboratory studies showed white blood cell count of 18.5 K/mm3, sodium of 131 mmol/L, creatinine of 1.6 mg/dL, and CD4 count of 567 cells/mm3. The random morning cortisol level was 7.0 µg/dL, the ACTH stimulation test yielded inappropriate response, and a random serum ACTH was elevated at 83.4 pg/mL. MRI brain revealed no pituitary adenoma confirming primary adrenal insufficiency. The adrenal CT washout study was consistent with solid mass content, concerning for metastasis. Bronchoscopy with endobronchial mass and paratracheal lymph node biopsy confirmed small-cell lung cancer (SCLC). Intravenous steroids, 100 mg hydrocortisone every 8 hours, improved his hypotension and abdominal pain. PET scan revealed metabolically active right paratracheal mass, right hilar mass, and bilateral adrenal masses. Treatment included palliative chemotherapy consisting of carboplatin/etoposide/atezolizumab and chest radiation. We present this novel case to demonstrate SCLC's ability to cause primary adrenal insufficiency, as well as evaluate clinical response to chemotherapeutics.
