Delayed Recognition of Levetiracetam-induced Pancytopenia

Blood dyscrasias associated with levetiracetam use can be difficult to identify, especially when other potential differential diagnoses are concurrently present. Here we present a 57-year-old man with metastatic adenocarcinoma of unknown primary origin on levetiracetam who initially presented with an in-stent thrombosis of the right external iliac vein and then developed worsening thrombocytopenia followed by pancytopenia. Levetiracetam was not identified as the culprit until other causes like platelet consumption, heparin-induced thrombocytopenia, idiopathic immune thrombocytopenic purpura, and bone marrow involvement by metastatic disease were ruled out

Leg Ulcer with Long-Term Hydroxyurea Use

Long-term use of hydroxyurea can cause leg ulcers which usually do not heal unless the drug is discontinued. Patients should be counseled regarding alternative lines of treatment like anagrelide and pegylated-interferon

Hepatosplenic T-Cell Lymphoma in an Immunocompetent Young Male: A Challenging Diagnosis

Hepatosplenic T-cell lymphoma is a rare but highly aggressive form of T-cell malignancy. As cases are not routinely seen in practice, the malignancy can be confused with other hematologic conditions that have a similar presentation. Here in, we present the challenges faced in diagnosing a 27-year-old-male who initially presented with asymptomatic pancytopenia and then developed massive splenomegaly over the next three months. After an elaborate workup, including a bone marrow biopsy and extensive serological testing, which all turned out to be negative, he eventually underwent a splenectomy with biopsy results confirming hepatosplenic T-cell lymphoma

Anaplastic Large Cell Lymphoma Presenting as Haemophagocytic Lymphohistiocytosis with Underlying Coxiella burnetii and Bartonella henselae Seropositivity

A 44-year-old woman with no significant medical history presented with a 3-week history of high-grade fevers, fatigue and shortness of breath. Laboratory investigation was significant for lymphopenia and thrombocytopenia which progressively worsened during her hospital stay, along with new-onset anaemia, and elevated ferritin, transaminase and triglycerides. A computerized tomography (CT) scan of the abdomen revealed retroperitoneal lymphadenopathy. A bone marrow biopsy confirmed the diagnosis of haemophagocytic lymphohistiocytosis (HLH). Extensive infectious work-up revealed high IgG titres for LEARNING POINTS: Haemophagocytic lymphohistiocytosis (HLH) is an important differential diagnosis to consider for fever of unknown origin in adults, especially in the setting of pancytopenia and hyperferritinaemia.Q fever resulting fro

Suspected Metformin-induced Cobalamin Deficiency Mimicking Thrombotic Thrombocytopenic Purpura

Thrombotic thrombocytopenic purpura (TTP) can often be life threatening and requires timely diagnosis and prompt initiation of plasmapharesis. Cobalamin deficiency can closely mimic TTP and distinguishing between the two diseases can prove to be a diagnostic challenge. Previously, cobalamin-related pseudo-TTP has been associated with pernicious anemia, dietary insufficiency and hereditary disorders of cobalamin activation. Here in, we discuss the first case of suspected metformin-induced cobalamin deficiency causing pseudo-TTP. Our patient was a 36-year-old female with type 2 diabetes mellitus on metformin for eight years who presented with hemolytic anemia, thrombocytopenia, schistocytes and mild acute renal failure. The initial impression was TTP; however, further workup revealed very low serum cobalamin levels and elevated methylmalonic acid levels. Apart from metformin use, no other cause of cobalamin deficiency was identified. We recommended upper gastrointestinal endoscopy to definitively rule out pernicious anemia

Spontaneous tumor lysis syndrome in squamous cell carcinoma of the lung

Tumor lysis syndrome (TLS) is an oncologic emergency, more commonly occurring in patients with hematologic malignancies receiving cancer-directed therapy due to massive cellular breakdown. Spontaneous TLS is rare and occurs in the absence of cancer-directed therapy. Herein, we present a case of spontaneous TLS associated with squamous cell carcinoma

Synthesis of highly stable MOF-5@MWCNTs nanocomposite with improved hydrophobic properties

Metal-organic frameworks (MOFs) are a promising class of nanoporous crystalline materials with potential applications in gas storage, catalysis, biomedical and clean energy. However, moisture adsorption dampens their structure and therefore capacity and selectivity. Improving the hydrostability of MOF-5 without compromising on its characteristic features can be a potential way to make the best use of this material. In this work, we used a solvothermal method to precipitate MOF-5 in well-dispersed carboxy derived MWCNTs. By inspiring from the hydrophobic properties of carbon nanotubes (CNTs), we have successfully utilized a solvothermal approach to precipitate MOF-5 in well-dispersed carboxy functionalized multiwalled carbon nanotubes (FMWCNTs) to produce a MOF-5@FMWCNTs nanocomposite. The experimental results in this study reveal that the FMWCNTs form stable nanocomposite with MOF-5 particles and the resultant hybrid MOF-5@FMWCNTs nanocomposite indicated an increase in the moisture stability and even after prolonged exposure to ambient moist environment (55% humidity at 28 °C) showed less degradation as confirmed by the BET surface area, and powder XRD studies. So, our findings demonstrate a simple synthetic route to make use of FMWCNTs to stabilize the MOF-5 and it can be a choice for many other MOFs without much compromise on the surface area

The Impact of Atrial Fibrillation on hospitalization Outcomes for Patients With Chronic Lymphocytic Leukemia Using the National Inpatient Sample Database

Background: The incidence of atrial fibrillation (AF) in patients with chronic lymphocytic leukemia (CLL) has been on the rise. However, the excess burden added by AF to the morbidity and mortality of CLL patients especially in the hospitalized setting is undetermined. Methods: The National Inpatient Sample (NIS) database was accessed to gather data of hospitalized CLL patients with AF from 2009 to 2018. Propensity-score matching (PSM) and logistic regression model were performed to control for baseline patient factors to match 7265 CLL patient admissions with AF and 7265 CLL patient admissions without AF. The primary outcome was all-cause mortality (ACM), while the secondary outcomes included acute coronary syndrome (ACS), acute myocardial infarction (AMI), and the need for percutaneous coronary intervention (PCI), acute heart failure (AHF), acute hypoxic respiratory failure (AHRF), cardiac arrest (CA), cardiogenic shock (CS), stroke, and the total cost of hospitalization. Results: CLL patients with AF had a higher rate of ACM (6.06% vs 4.47%; odds ratio [OR] 1.39, 95% confidence interval [CI] 1.19-1.61; P =\u3c.001). All other secondary outcomes including ACS, AMI, PCI, AHRF, CA, CS, and stroke were observed at a significantly higher rate in the AF group as well. The median total hospital cost was also higher in the AF group ($9097 vs.$7646; P value \u3c.0001) Conclusion: CLL patients with AF are at a significantly increased risk of all-cause mortality, cardiac-related mortality, and stroke. For this population, a multidisciplinary approach should be orchestrated for better management and outcomes
