Gallbladder Neuroendocrine Carcinoma: A Rare Endocrine Tumor.

Gallbladder neuroendocrine neoplasms (GB-NEN) are very rare neuroendocrine tumors (NETs). GB-NEN can present as carcinoid or typical/atypical carcinoid or small cell carcinoma. Most of the GB-NENs present as gall bladder polyps or stones with right upper quadrant pain, nausea and non-specific symptoms which leads to clinical misdiagnosis. Considering the rare occurrence of GB-NENs, and lack of multi-center research data there is no unified standard for identification and treatment. We here present an 84-year-old male presenting with right upper quadrant and epigastric pain, and eventually diagnosed with mixed cell (more of small cells mixed with intermediate to large cells) neuroendocrine cancer of gall bladder.

Multiple Intracranial Tuberculomas with an Intra-medullary Spinal Cord Tuberculoma in a Pediatric Patient.

Central nervous system (CNS) tuberculosis (TB), caused by Mycobacterium tuberculosis (MT), is a severe form of TB, which presents as meningitis, cerebritis, abscesses, spinal tuberculous arachnoiditis, and rarely tuberculomas. CNS TB is prevalent in the underdeveloped or developing world and is common in malnourished, alcoholics, children, young adults, immunocompromised, and cancer patients. Intracranial tuberculomas (ICT) can present with symptoms and signs of focal neurological deficits with or without systemic manifestations. ICT is the least common presentation of CNS TB. Medical management with anti-TB drugs and steroids is the mainstay of treatment, while surgical intervention is usually reserved for refractory cases. Here, we present the case of a 10-year-old Indian American girl with headaches, diplopia, fever, and neck pain diagnosed with ICT and intramedullary spinal cord tuberculoma.

Isolated Area Postrema Syndrome Presenting as Intractable Nausea and Vomiting.

Neuromyelitis optica (NMO) is a disease of central nervous system, characterized by demyelination and axonal damage mostly involving optic nerves and spinal cord. Usually these patients present with symptoms related to optic neuritis or myelitis with a typical relapsing course. Some patients present with less common symptoms involving brain stem like nausea and vomiting, especially those involving area postrema (AP) located in dorsal medulla. International panel for NMO diagnosis revised criteria in 2015 and came up with a unifying term NMO spectrum disorders (NMOSD) instead of NMO. Patients with NMO having AP involvement are grouped under area postrema syndrome (APS). Usually patients with AP symptoms also have neurological symptoms upon presentation. Here we present a rare case of an NMO who presented with isolated APS with no other neurological symptoms.

New Delhi Metallo-beta-lactamase-producing Enterobacter Cloacae - A Rare Multidrug Resistance Strain in a Caucasian Woman.

New Delhi metallo-beta-lactamase (NDM-1) is a novel metallo-beta-lactamase (MBL) gene carried by some Enterobacteriaceae that induces resistance to most of the antibiotics. First described in a Swedish patient hospitalized in India with an infection due to Klebsiella pneumoniae. NDM-1 makes bacteria resistant to a broad range of beta-lactam antibiotics. These include the antibiotics of the carbapenem family, which are a mainstay for the treatment of antibiotic-resistant bacterial infections. Most of these carbapenem resistant Enterobacteriaceae (CRE) are increasingly recognized in hospital settings and post-acute care settings like long-term acute care settings. Percentage of CRE infections is increasing in the United States of America, and invasive infections with CRE carry high mortality rates and limited treatment options. We here present a rare case of elderly Caucasian woman with CRE cellulitis of both legs with no travel history.

Euglycemic Diabetic Ketoacidosis in a Young Pregnant Woman Precipitated by Urinary Tract Infection.

Diabetic ketoacidosis (DKA) is a life-threatening diabetic complication and medical emergency. Euglycemic DKA (EKDA) is a variant of DKA with normal range glucose levels. The condition can be difficult to diagnose due to the misleading euglycemic levels. Pregnancy, infection, low-calorie intake, and use of insulin are some of the common etiologies of EDKA. We report a case of a young, pregnant female, with type I diabetes mellitus, in her third trimester admitted with EKDA. The EKDA was triggered by urinary tract infection (UTI), and the patient had other etiologies that have predisposed her to EKDA. Along with the case presentation, we discuss the common etiologies, pathophysiology, and management of EKDA. Euglycemic DKA is a life-threatening emergency that needs to be recognized early and treated aggressively, especially in pregnant patients, to avoid deleterious effects to maternal and fetal health.

Severe Respiratory Alkalosis in Acute Ischemic Stroke: A Rare Presentation.

Respiratory alkalosis is a rare but severe complication of acute ischemic stroke (AIS). In ischemic stroke, respiratory alkalosis results from hyperventilation due to the effect of stroke on the respiratory center. We report a case of a young male who presented with acute encephalopathy. Work-up revealed ischemic infarcts in the bilateral cerebellar and left posterior cerebral artery territory. Arterial blood gas (ABG) showed severe respiratory alkalosis with a pH of 7.72. Alkalosis resolved with mechanical ventilation. Such a high pH associated with AIS has not been reported in the medical literature so far. The index case highlights the severity of respiratory alkalosis that can be caused by an AIS. We conclude that early diagnosis and management of severe respiratory alkalosis is crucial for survival and recovery.

Staphylococcus warneri: Skin Commensal and a Rare Cause of Urinary Tract Infection.

Coagulase negative Staphylococci often grow in cultures and form one of the most abundant flora among skin microbiome. It is important and challenging to identify and treat clinically significant infections caused by these organisms. Prosthetic devices, catheters and conditions causing immunocompromised states are the risk factors for such infections. We describe a case of clinically significant and symptomatic urinary tract infection (UTI) in a 65-year-old man with liver cirrhosis caused by Staphylococcus warneri which forms <1% of Staphylococcal skin flora. He was treated successfully with fluoroquinolone antibiotic based on culture results. It is important to understand potential of this organism to cause serious infections which warrant culture-directed antibiotic therapy.

Recurrent Cholangiocarcinoma Presenting as Sister Mary Joseph Nodule After Liver Transplantation.

Hilar cholangiocarcinoma, also known as Klatskin tumor, is the most common type of cholangiocarcinoma. It usually has a lymphatic spread and is rarely associated with an umbilical nodule, also known as Sister Mary Joseph nodule. We report a case of a 53-year-old Caucasian man with hilar cholangiocarcinoma. The patient had an inoperable tumor and was referred to our center for liver transplantation. Post liver transplantation, the patient presented with a recurrence of the carcinoma in the umbilical region. The patient was found to have Sister Mary Joseph nodule. It carries a poor prognosis, and our patient succumbed to the illness in four months. Cholangiocarcinoma carries a poor prognosis. Surgical resection and liver transplantation with neoadjuvant chemoradiation are the preferred treatment strategies. Association of cholangiocarcinoma with umbilical metastasis is rare, and our patient had an even rarer presentation in the form of recurrence with umbilical nodule post-liver transplantation. We want to increase the awareness of the rare presentation, association, and recurrence of hilar cholangiocarcinoma in the form of umbilical nodule post-liver transplantation.

Albuterol-Induced Type B Lactic Acidosis: Not an Uncommon Finding.

Lactic acidosis (LA) is usually a medical emergency diagnosed by laboratory evaluation in emergency rooms (ERs) and hospital settings in critically ill patients. LA is classified into two major types based on pathophysiology; type A results from tissue hypoxia and/or hypoperfusion and type B results from deranged metabolic activity in the cells in the absence of hypoxia/hypoperfusion. Prompt evaluation and treatment are essential to prevent morbidity and mortality, especially in patients with type A LA. Most cases of LA are due to type A (hypoperfusion/hypoxia). However, with increased testing of lactic acid levels in ERs and hospitals, we are encountering a few cases of type B LA as well. Diagnosing the exact type is crucial because of differences in management. We here describe a patient with albuterol-induced type B LA, which resolved after discontinuing the albuterol breathing treatments.

Coronavirus Disease 2019-Induced Rhabdomyolysis.

Rhabdomyolysis is caused by necrosis of muscles and leakage of intracellular contents into blood circulation. It is most commonly caused by trauma, crush injuries, drugs, toxins, immobilization, compartment syndrome, prolonged surgical procedures, and less likely by infections. Infection-related rhabdomyolysis is rare, but not uncommon, and is seen in both viral and bacterial infections. Extrapulmonary manifestations of coronavirus disease 2019 (COVID-19) include thrombotic like pulmonary emboli, acute cerebrovascular accident, myocardial infarction, cardiac arrhythmias, liver injury, gangrene, diarrhea, acute renal failure, and so on. We here describe a case of COVID-19-induced rhabdomyolysis in a 19-year-old Hispanic male presenting with muscle aches, fatigue, fevers, and no pulmonary symptoms.

Guillain-Barre Syndrome and Syndrome of Inappropriate Antidiuretic Hormone (SIADH) Secretion as Paraneoplastic Syndromes in Splenic Marginal B-cell Non-Hodgkins Lymphoma: A Rare Presentation.

Splenic marginal zone lymphoma (SMZL), a rare sub-type of non-Hodgkin lymphoma (NHL) presents with abdominal discomfort, lymphocytosis, cytopenias along with B symptoms including fatigue, night sweats, night fevers, weight loss. NHLs rarely present with paraneoplastic neurological syndromes like Guillain-Barre (GB) syndrome, myelopathy causing paraplegia, chorea, neuromyotonia, vasculitic neuropathy and dermatomyositis. Here, we present a 85-year old caucasian lady presenting with GB syndrome and Syndrome of Inappropriate Antidiuretic Hormone (SIADH) who eventually got diagnosed with SMZL.

Atypical Presentation of Novel Coronavirus Disease 2019 in a Peritoneal Dialysis Patient.

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a rapidly spreading disease causing increased morbidity and mortality across the globe. There is limited available knowledge regarding the natural history of the SARS-CoV-2 infection. Other factors that are also making this infection spread like a pandemic include global travelers, lack of proven treatment, asymptomatic carriers, potential reinfection, underprepared global health care systems, and lack of public awareness and efforts to prevent further spread. It is understood that certain preexisting medical conditions increase the risk of mortality with COVID-19; however, the outcome of this disease in traditionally vulnerable chronic illnesses such as end-stage renal disease is not well documented. We present a case of a 56-year-old African American lady with end-stage renal disease on the peritoneal dialysis who presented predominantly with nausea, vomiting, and subsequently found to have COVID-19. We use this case to illustrate an atypical presentation of the COVID-19 in a vulnerable patient and discuss the literature.

COVID-19 and Renal Failure: Challenges in the Delivery of Renal Replacement Therapy.

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first officially reported in December 2019 in Wuhan City, Hubei province, China, and has since lead to a pandemic. Most cases result in minor symptoms such as cough, fever, sore throat, myalgia, fatigue, nausea, diarrhea, loss of smell, and abdominal pain. As of April 8, 2020, more than 1,485,000 cases of COVID-19 have been reported in more than 200 countries and territories, resulting in over 90,000 deaths. Outcomes are worse in elderly patients, particularly males, and those with comorbidities, but can affect any age group. The incidence of acute kidney injury in patients with COVID-19 infection is about 3-15%; and in patients with severe infection requiring care in the intensive care unit, the rates of acute kidney injury increased significantly from 15% to 50%. Acute kidney injury is an independent risk factor for mortality in COVID-19 patients. The nephrologists, as well as intensivists, are facing immense daily challenges while providing care for these patients in the inpatient setting as well as end-stage renal disease patients on chronic dialysis in both inpatient and outpatient settings. In the current review article, we discussed the epidemiology and etiology of acute kidney injury, management of acute kidney injury including renal replacement therapy options (both hemodialysis and peritoneal dialysis) for inpatient floor, as well as intensive care unit settings. We also discussed the challenges faced by the outpatient dialysis units with COVID-19 infection. We discussed measures required to limit the spread of infection, as well as summarized the guidance as per the Centers for Disease Control and Prevention (CDC), American Society of Nephrology (ASN), American Society of Diagnostic and Interventional Nephrology (ASDIN) and the Vascular Access Society of the Americas (VASA).

Medical Management of COVID-19: Evidence and Experience.

Coronavirus disease 2019 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and this infectious disease is termed COVID-19 in short. On a global scale, as of June 1, 2020, the World Health Organization (WHO) published statistics of 6,057,853 infected patients and 371,166 deaths worldwide. Despite reported observational data about the experimental use of certain drugs, there is no conclusively proven curative therapy for COVID-19 as of now; however, remdesivir received emergency use authorization (EUA) by the Food and Drug Administration (FDA) recently for use in patients hospitalized with COVID-19. There are several ongoing clinical trials related to the pharmacological choices of therapy for COVID-19 patients; however, drug trials related to observational studies so far have yielded mixed results and therefore have created a sense of confusion among healthcare professionals (HCPs). In this review article, we seek to collate and provide a summary of treatment strategies for COVID-19 patients with a variable degree of illness and discuss pharmacologic and other therapies intended to be used either as experimental medicine/therapy or as part of supportive care in complicated cases of COVID-19.

Medical Management of Pump-Related Thrombosis in Patients with Continuous-Flow Left Ventricular Assist Devices: A Systematic Review and Meta-Analysis.

Pump thrombosis is a dreaded complication of left ventricular assist devices (LVADs). We completed a systematic review to evaluate the efficacy and complications associated with medical management of LVAD thrombosis. Databases were searched using the terms "vad*" or "ventricular assist device" or "heart assist device" and "thrombus" or "thrombosis" or "thromboembolism." Of 2,383 manuscripts, 49 articles met the inclusion criteria. The risk of partial or no resolution of LVAD thrombosis did not significantly differ between thrombolytic and nonthrombolytic regimens (odds ratio [OR], 0.48; 95% confidence interval [CI], 0.20-1.16). When response to therapy was evaluated based on pump type, there were no significant differences in how patients with a HeartMate II or HeartWare ventricular assist device responded to thrombolytic or nonthrombolytic treatment. Pooled risk of major bleeding in the thrombolytic group was 29% (95% CI, 0.17-0.44) and 12% (95% CI, 0.01-0.57) in the nonthrombolytic group. Odds of death did not differ between thrombolytic and nonthrombolytic regimens (OR, 1.28; 95% CI, 0.42-3.89). Although thrombolytic and nonthrombolytic treatment similarly resolved LVAD thrombosis, major hemorrhage may be increased with the use of thrombolysis. Randomized clinical trials comparing thrombolytic and nonthrombolytic treatment of LVAD thrombosis are needed to establish the most effective and safe option for patients who are not surgical candidates.
