RESUMEN
ABSTRACT: This study aimed to characterize survivors of Coronavirus disease 2019 (COVID-19) infection and acute kidney injury (AKI) that recover their renal function or progress to acute kidney disease (AKD) on discharge; and determine factors associated with progression to AKD during hospital stay.One thousand seventy four patients with COVID-19 infection were followed up until discharge/death. The incidence of AKI was 59.7%. Two hundred and sixty-six patients were discharged alive and included in the analysis, 71.8% had renal recovery (RR) while 28.2% were discharged with AKD. The AKD subset has higher rate of chronic kidney disease (CKD) ≥3 (33.4% vs 14.1%, P = .001), congestive heart failure (18.7% vs 5.8%, P = .001), use of non-invasive mechanical ventilation (10.7% vs 3.7%, P = .026) and vasopressors (25.3% vs 12.0%, P = .007). Of 19 patients in the AKI survivor cohort who received renal replacement therapy, 1 had RR while 18 progressed to AKD on discharge. Predictors to progression to AKD were CKD ≥3 (Odds Ratio [OR]: 3.23, 95% confidence interval [CI] 1.59-6.56, P = .001), congestive heart failure (OR: 4.59, 95% CI 1.76-11.78, P = .002), AKI on admission (OR: 2.71, 95% CI, 1.14-6.46, P = .025), and ongoing diarrhea (OR: 3.19, 95% CI, 1.02-9.96, P = .025).This study demonstrates a higher proportion of RR among survivors of COVID-19 infection in our minority predominant cohort. Early identification and appropriate management of patients at-risk to progress to AKD could improve outcomes, reduce long term sequalae of CKD/end stage renal disease, and have a major impact on health outcome and financial strain on healthcare system.

Ascariasis, which is caused by Ascaris lumbricoides, is the most common gastrointestinal parasitic infection worldwide, with occasional invasion of the biliary tract leading to a variety of complications. In rare cases, pathogens carried on the surface of A. lumbricoides can complicate the course of the disease and lead to superimposed bacterial infections. In this article, we present a case of ascariasis-induced cholangitis complicated with Klebsiella pneumoniae bacteremia and multiple hepatic microabscesses. This article, which shows an association that was not reported in the literature before, aims to increase the awareness of clinicians for the possibility of the association between ascariasis and superimposed bacterial infection, specifically with K. pneumoniae.
RESUMEN
BACKGROUND: New York City (NYC) has endured the greatest burden of COVID-19 infections in the US. Health inequities in South Bronx predisposed this community to a large number of infectious cases, hospitalizations, and mortality. Health care workers (HCWs) are at a high risk of exposure to the infection. This study aims to assess seroprevalence and the associated characteristics of consenting HCWs from an NYC public hospital. METHODS: This cross-sectional study includes serum samples for qualitative SARS-CoV-2 antibody testing with nasopharyngeal swabs for SARS-CoV-2; PCR and completion of an online survey capturing demographics, COVID-19 symptoms during the preceding months on duty, details of healthcare and community exposure, and travel history were collected from consenting participants in May 2020. Participants' risk of exposure to COVID-19 infection in the hospital and in the community was defined based on CDC guidelines. Travel history to high-risk areas was also considered an additional risk. The Odds Ratio with bivariable and multivariable logistic regression was used to assess characteristics associated with seroprevalence. RESULTS: A total of 500 HCW were tested, 137 (27%) tested positive for the SARS-CoV-2 antibody. Symptomatic participants had a 75% rate of seroconversion compared to those without symptoms. Subjects with anosmia and ageusia had increased odds of seroconversion in comparison to those without these symptoms. Community exposure was 34% among those who had positive antibodies. CONCLUSION: Seroprevalence among HCWs was high compared to the community at the epicenter of the pandemic. Further studies to evaluate sustained adaptive immunity in this high-risk group will guide our response to a future surge.

Dermatomyositis sine dermatitis (DMSD) is a rare autoimmune disease. It's distinguished from classical dermatomyositis (DM) by a lack of skin involvement. DM is known to have a variety of extramuscular manifestations, including interstitial lung disease, myocarditis, and dysphagia. However, peripheral nervous system involvement in DM termed "Neuromyositis" is less often encountered. Neuromyositis diagnosis is controversial due to its rarity, unknown mechanism, and heterogeneity of nerve pathology findings. A 53-year-old woman presented to our hospital following a fall. Six months prior to presentation, she had a sensory disturbance in her right foot. On admission, she had a right foot drop that progressed to right then left lower extremity weakness. A biopsy of the superficial peroneal nerve and long peroneal muscle showed large fiber nerve axonal loss, CD20 B-cell and CD4 T-cell predominant inflammatory infiltrate involving the perimysial connective tissue of the muscle, as well as myocyte hypertrophy and fibrosis with type I fiber predominance. These findings were compatible with dermatomyositis with neuropathic features. Electrophysiological studies of lower extremities revealed severe widespread axonal dysfunction, as evidenced by decreased tibial compound muscle action potential (CMAP), no peroneal motor responses, absent sural sensory nerve action potential (SNAP), and extensive active denervation throughout the left lower extremity. Three months later, she developed bilateral upper extremity weakness. A biopsy of the deltoid muscle that was done eight months after admission showed CD20 B-cell and CD4 T-cell predominant inflammatory infiltrates involving the perimysial connective tissue. These findings were pathologically similar to the first biopsy. Subsequently, a repeat electromyography (EMG) of upper extremities revealed myopathic changes with normal nerve conductions. She ultimately became quadriplegic and ventilator-dependent nine months after admission. She never exhibited any skin findings throughout her course of illness. An extensive imaging and laboratory workup did not reveal any occult malignancy, inflammation, or nutritional deficiency. Our patient did not respond to steroids or intravenous immunoglobulin (IVIg) and ultimately passed away. The clinical, pathological, and electrophysiological features suggested the presence of neuromyositis. This case illustrates the importance of recognizing peripheral nervous system involvement as a significant and yet underreported extramuscular manifestation of DM. There are currently no formal management guidelines for neuromyositis.
RESUMEN
Diagnosing myocardial infarction is not always straightforward; there are many insidious presentations that can be overlooked resulting in deadly consequences. We present a 76-year-old male who came to the ED complaining of right ankle pain. A routine electrocardiogram (ECG) done was noted to have biphasic T waves in leads V2 and V3 which was characteristic of Wellens' syndrome. Subsequent workup showed an increase in troponin T levels in a chest pain-free setting. The patient underwent urgent cardiac catheterization which showed significant triple vessel coronary artery disease, with 90% proximal occlusion of the left anterior descending artery, eventually requiring coronary artery bypass grafting (CABG). Timely diagnosis and management prevented serious consequences of his underlying severe coronary artery disease.
RESUMEN
Paraneoplastic syndromes occur in the presence of a tumor and are known to cause a myriad of systemic manifestations by mechanisms other than direct metastasis. Although considered to be rare, tumors can cause paraneoplastic rheumatological manifestations such as paraneoplastic arthritis. Differentiating between paraneoplastic arthritis and primary rheumatoid arthritis (RA) presents a diagnostic challenge to physicians. Here we describe a case of an 83-year-old male with complaints of painful joint swelling of his hands, elbows, and feet. Subsequent tests ultimately led to the diagnosis of gastric cancer with associated paraneoplastic arthritis. We highlight the physical, laboratory, and imaging findings associated with the diagnosis of paraneoplastic arthritis with emphasis on the differences between this diagnosis and that of RA. Despite the uncommon nature of paraneoplastic arthritis, it remains of paramount importance to be aware of its association with malignancies, aiding in possible earlier diagnosis.
RESUMEN
Moyamoya disease is a rare cerebrovascular disease of unknown etiology, once known to be rare in the United States as compared to East-Asian countries, it is now an increasingly recognized cause of strokes in the United States, as the prevalence of the disease appears to be increasing. We describe a case of a 41-year-old Hispanic female patient presenting to our hospital with a stroke. She had two episodes of right arm weakness and clumsiness prior to presentation to the hospital that had resolved upon arrival. Despite a CT head negative for stroke, further imaging work-up was performed including MRI of the brain with magnetic resonance angiography (MRA) and conventional angiogram, which showed characteristic imaging findings leading to the diagnosis of Moyamoya disease. The patient subsequently underwent elective surgical intervention with Encephaloduroarteriosynangiosis (EDAS) procedure to prevent further complications.
