A case of celiac plexus block causing iatrogenic Cushing's syndrome.

Treatment with corticosteroids can lead to iatrogenic Cushing's syndrome when used for longer intervals and in high doses. Less common administration routes may conceal the exposure, raising the possibility of misdiagnosis and mismanagement.

Clinical and Radiological Characterization of Central Nervous System Involvement in Nocardiosis: A 20-Year Experience.

Background This study aimed to present the clinical and radiological characteristics and the outcomes of patients with Nocardia infection of the central nervous system (CNS). Methodology We conducted a retrospective review of patients aged 18 and older admitted between August 1998 and November 2018 with culture-proven nocardiosis and CNS involvement. Results Out of 110 patients with nocardiosis, 14 (12.7%) patients had CNS involvement. The median age was 54.5 (27, 86) years, and 12 (85.7%) patients were male. Overall, 12 (85.7%) patients were immunosuppressed on high doses of glucocorticoids; seven (50%) patients were solid organ transplant recipients. Only eight (57.1%) patients had neurological symptoms at presentation, and the rest were diagnosed with CNS involvement after imaging surveillance. Three distinct radiologic patterns were identified, namely, single or multiple abscesses, focal cerebritis, and small, septic embolic infarcts. All isolates of Nocardia were susceptible to trimethoprim/sulfamethoxazole and amikacin, with susceptibility to linezolid and carbapenems being 90.9% and 79.5%, respectively. Despite receiving antibiotic therapy, six (42.8%) patients died, most of them within weeks of initial admission. All surviving patients underwent prolonged antimicrobial therapy until the resolution of MRI abnormalities. All solid organ transplant recipients recovered. Conclusions Nocardia CNS infection was a rare condition, even among a large, immunosuppressed patient population. CNS imaging surveillance is paramount for immunosuppressed patients with nocardiosis, as CNS involvement influences the choice and duration of therapy. Nocardia antibiotic susceptibility varied widely between strains and the empiric therapy should consist of multiple classes of antimicrobials with CNS penetration. Mortality was high, but all solid organ transplant recipients recovered.

Autoimmune Hepatitis: A Diagnostic and Therapeutic Overview.

Autoimmune hepatitis is an immune-mediated inflammatory condition of the liver of undetermined cause that affects both sexes, all ages, races, and ethnicities. Its clinical presentation can be very broad, from having an asymptomatic and silent course to presenting as acute hepatitis, cirrhosis, and acute liver failure potentially requiring liver transplantation. The diagnosis is based on histological abnormalities (interface hepatitis), characteristic clinical and laboratory findings (increased aspartate aminotransferase, alanine aminotransferase, and serum IgG concentration), and the presence of one or more characteristic autoantibodies. The large heterogeneity of these clinical, biochemical, and histological findings can sometimes make a timely and proper diagnosis a difficult task. Treatment seeks to achieve remission of the disease and prevent further progression of liver disease. First-line therapy includes high-dose corticosteroids, which are later tapered to decrease side effects, and azathioprine. In the presence of azathioprine intolerance or a poor response to the standard of care, second-line therapy needs to be considered, including mycophenolate mofetil. AIH remains a diagnostic and therapeutic challenge, and a further understanding of the pathophysiological pathways of the disease and the implementation of randomized controlled trials are needed.

Hydroxychloroquine Induced Cardiotoxicity: A Case Series.

Hydroxychloroquine (HCQ) induced cardiotoxicity is a rare diagnosis and is often associated with chronic use of the medication. It has been shown that chronic HCQ use is associated with a drug-induced cardiomyopathy mainly driven by acquired lysosomal storage defects leading to hypertrophy and conduction abnormalities. As the only proven treatment is the discontinuation of the offending agent, prompt recognition is required to avoid further exposure to the drug and potential progression of disease. History, physical examination and advanced imaging modalities are useful diagnostic tools, but more invasive testing with an endomyocardial biopsy is required for definitive diagnosis. We present a descriptive case series of ten patients that were diagnosed with biopsy proven HCQ cardiotoxicity.

Expanding the Role of the Surgical Preoperative Evaluation Clinic: Impact on Risk and Quality Outcome Measures.

Objective: To prove that inpatient-adjusted surgical risk and quality outcome measures can be considerably impacted by interventions to improve documentation in the preoperative evaluation (POE) clinic. Patients and Methods: We designed a quality improvement project with a multidisciplinary team in our POE clinic to more accurately reflect surgical risk and impact expected surgical quality outcomes through improved documentation. Interventions included an improved patient record acquisition process and extensive POE provider education regarding patient comorbidities' documentation. For patients admitted after their planned operations, POE clinic comprehensive evaluation notes were linked to inpatient History and Physical notes. High complexity patients seen from October 1, 2018 to December 31, 2018 were the preintervention cohort, and the patients seen from January 1, 2019 to December 31, 2019 were the postintervention cohort. Results: The primary outcome measures included the total number of coded diagnoses per encounter and the number of coded hierarchical condition categories per encounter. The secondary outcomes included the calculated severity of illness, risk of mortality, case-mix index, and risk-adjustment factor. Postintervention results show statistically significant increases in all primary outcomes with a P<.05. All secondary outcome measures reported positive change. Conclusion: Our interventions confirm that a comprehensive POE and thorough documentation provide a more accurate clinical depiction of the preoperative patient, which in turn impacts quality outcomes in inpatient surgical settings. These results are impactful for direct and indirect patient care and publicly reported hospital and provider level performance data.

Trigeminal Amyloidoma in a Patient With Cardiac Amyloidosis.

Trigeminal amyloidoma is a rare clinical phenomenon with scarce reports in the medical literature. This report presents a case of biopsy-proven trigeminal amyloidoma in a patient with cardiac amyloidosis. This case report sheds light on the differential diagnoses that may resemble trigeminal amyloidoma and strategies for workup and treatment.

A Rare Case of Cardiac Tamponade in a Patient With Anti-RNA Polymerase III Scleroderma.

Scleroderma is a chronic, progressive autoimmune disease that often presents with multiorgan involvement. Cardiac manifestations are common and include microvascular coronary artery disease, conduction abnormalities, autonomic insufficiency, and pericardial effusions. Although rare, pericardial effusions may progress and lead to cardiac tamponade. Patients diagnosed with scleroderma can be further prognosticated based on the presence of serologic scleroderma-specific antibodies. The anti-RNA polymerase III autoantibody (anti-RNAP3) is associated with an aggressive subtype of scleroderma. Looking at the current literature, no association has been reported between anti-RNAP3 and the development of cardiac tamponade in patients with underlying scleroderma. We discuss a unique case of a patient with scleroderma who was found to be anti-RNAP3 positive and signs of cardiac tamponade. This case illustrates the importance of an expeditious diagnosis and timely interventions to treat cardiac tamponade. Additionally, we share a rare but important association between anti-RNAP3 and the formation of tamponade physiology in scleroderma.

Acute Onset of Heart Failure and Renal Failure Due to Pacemaker Syndrome.

Here, we report the outcome of an 87-year-old man with permanent non-valvular atrial fibrillation who initially presented with complete heart block and received a single right ventricle lead pacemaker programmed to ventricular demand pacing (VVIR). Over the next 10 months, the patient was readmitted to the hospital four times with recurrent edema, pleural effusions, and ascites. He was diagnosed with new onset systolic heart failure with mid-range (40-49%) ejection fraction and cardiorenal syndrome requiring dialysis. The underlying cause of his presentation was determined to be pacemaker syndrome mediated by new onset severe tricuspid regurgitation. He was treated with reimplantation of a pacemaker with His bundle pacing with subsequent improvement in his cardiac status and renal function. Implantation of dual-chamber pacing (DDDR) or His bundle pacing to achieve a narrow QRS complex over ventricular demand pacemaker is recommended whenever possible to reduce the incidence of pacemaker syndrome and improve patient outcomes.

Cardio-Oncology for the Primary Care Provider.

Cardiovascular disease is a major cause of mortality among oncologic patients. As cancer therapies continue to evolve and advance, cancer survival rates have been increasing and so has the burden of cardiovascular disease within this population. For this reason, cardio-oncology plays an important role in promoting multidisciplinary care with the primary care provider, oncology, and cardiology. In this review, we discuss the roles of different providers, strategies to monitor patients receiving cardiotoxic therapies, and summarize cancer therapy class-specific toxicities. Continued collaboration among providers and ongoing research related to cardiotoxic cancer therapies will enable patients to receive maximal, evidence-based, comprehensive care.

ANKRD26 Gene Variant of Uncertain Significance in a Patient With Acute Myeloid Leukemia.

ANKRD26-related thrombocytopenia is a rare inherited disorder associated with an increased risk of malignancy. While the genetic mutations underlying this condition are well understood, there is limited knowledge regarding its contribution to myeloid neoplasms, such as acute myeloid leukemia (AML). We present a case of ANKRD26-related thrombocytopenia with a variant of uncertain significance in a patient with AML and review the pathogenesis and implications of hereditary germline mutations in disease management.

Invasive Nocardiosis Versus Colonization at a Tertiary Care Center: Clinical and Radiological Characteristics.

Objective: To describe the clinical and radiographic findings in a large cohort of patients with positive cultures for Nocardia emphasizing the differences between invasive disease and colonization. Patients and Methods: We conducted a single-center, retrospective cohort study of 133 patients with a positive Nocardia isolate between August 1, 1998, and November 30, 2018, and a computed tomography (CT) of the chest within 30 days before or after the bacteria isolation date. Results: Patients with colonization were older (71 vs 65 years; P=.004), frequently with chronic obstructive pulmonary disease (56.8% vs 16.9%; P<.001) and coronary artery disease (47.7% vs 27%, P=.021), and had Nocardia isolated exclusively from lung specimens (100% vs 83.1%; P=.003). On CT of the chest, they had frequent airway disease (84.1% vs 51.7%; P<.001). Patients with invasive nocardiosis had significantly (P<.05) more diabetes, chronic kidney disease, solid organ transplant, use of corticosteroids, antirejection drugs, and prophylactic sulfa. They had more fever (25.8% vs 2.3%; P<.001), cutaneous lesions (14.6% vs 0%; P=.005), fatigue (18% vs 0%; P=.001), pulmonary nodules (52.8% vs 27.3%; P=.006), and free-flowing pleural fluid (63.6% vs 29.4%; P=.024). The patterns of nodule distribution were different-diffuse for invasive nocardiosis and peribronchiolar for Nocardia colonization. Conclusion: The isolation of Nocardia in sputum from a patient with respiratory symptoms does not equal active infection. Only by combining clinical and chest CT findings, one could better differentiate between invasive nocardiosis and Nocardia colonization.
