Paget-Schroetter syndrome in the absence of common predisposing factors: a case report.

BACKGROUND: Paget-Schrotter Syndrome (PSS) also known as "effort thrombosis" is a form of primary thrombosis in the subclavian vein at the costoclavicular junction is usually seen in younger patients after repeated strenuous activity of the shoulders and arms. When occurring in younger patients, PSS presents itself with predisposing factors such as unilateral dull, aching pain in the shoulder or axilla and swelling of the arm and hand. CASE PRESENTATION: We report a rare case of unusual left axillo-subclavian vein thrombosis in absence of clear risk factors and a negative hypercoagulable workup in a 36-year-old Hispanic woman who presented with 2 days duration of left upper extremity pain and swelling after a week of heavy exercise in aerobic class. Very few documented cases of primary or spontaneous ASVT in absence of clear factors and in such anatomical location have been previously reported. The patient was started on strict precautions of left upper extremity immobilization, analgesics in the form of Tylenol 650 mg every 6 h for pain as well as cold compresses. Lovenox 90 mg subcutaneous twice daily (1 mg/kg BID) was started together with warfarin to keep INR 2-3. CONCLUSION: In addition to the unusual location in the left upper extremity in our case, the absence of common etiologic factors makes our case of Paget-Schroetter Syndrome a very unique one. Presently, there is a lack of guided management of rare conditions such as our case, or consensus among the sources. Physicians should be aware of this rare disease since untreated conditions may be debilitating for the patient and very costly especially if diagnosed with a delay.

Retrospective Observational Study of Complete Blood Count (CBC) Parameters and ICU Mortality of COVID-19 Disease in Delta Variant and Omicron Variant in a Community-Based Hospital in New York City.

BACKGROUND: Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) is the official name of COVID-19, a respiratory infection that had the first case reported from the Hubei province of China on December 8, 2019. This virus is the main etiological agent behind the most dreaded pandemic of pneumonia that has spread to the entire world in a brief period and continues to pose a threat. The first wave corresponded with the period from February 2020 to June 2020, the Delta variant occurred around the middle of June 2021 and the Omicron wave was reported from December 2021 to February 2022. Objective: This study aims to compare the Delta and the Omicron variants of COVID-19 infection in a community-based hospital in New York City considering the comparison of ICU admissions in both variants. We aim to study the comparison of complete blood count (CBC) parameters and inflammatory markers of patients admitted to ICU stratified by two waves of COVID-19 infection. We aim to analyze the association of CBC parameters at admission and the discharge during ICU stay in both variants. We also aim to study the association of CBC parameters at admission and discharge with ICU mortality in both variants. METHODS: We conducted a retrospective observational study based on data from randomly selected hospitalized patients with COVID-19 in a community-based hospital in New York City during the Delta variant and the Omicron wave. A total of 211 patients COVID-19 positive from June to July 2021 (Delta variant) and 148 patients from December to February 2022 (Omicron wave) were included in the study. A comparison was done between the basic characteristics of patients with and without ICU admissions in both variants of COVID-19. We compared the relationship of different parameters of CBC (hemoglobin (Hgb), white blood count (WBC), lymphocytes, neutrophils, and platelets) on ICU admission and further analyzed any changes associated with ICU mortality. Logistic regression was performed to evaluate the relationship of different presenting CBCs on patients' disposition to ICU.  Result: A total of 211 patients (106 female) in the Delta wave (2021 variant) and 148 patients (80 female) in the Omicron wave (2022 variant) with an average ages of 60.9 ±18.10 (Delta variant) and 63.2 ± 19.10 (Omicron variant) were included in this study. There were 45 patients (21.3%) in the Delta wave and 42 patients (28.4%) in the Omicron wave were admitted to ICU. The average length of hospital stay was seven days in the Delta wave and nine days in the Omicron wave. No significant association was found between presenting cell count and ICU admission (p>0.05). Significant associations were found between different cell counts on admission and discharge and death in Delta waves except Hgb and platelets on admission. However, in the Omicron variant, a significant association was found only between WBC on admission and discharge, and Hgb and neutrophil on discharge with death in the univariate model. CONCLUSION:  Comparative study of different clinical parameters between the Delta and the Omicron variants of COVID-19 with the correlation of ICU stay and mortality can be used as a beneficial modality in assessing the outcome of the disease.

Cardiac Arrest (CA) as the Initial Presentation of Cocaine-Induced Takotsubo Cardiomyopathy (TCM): A Case Report and Review of Literature.

Cocaine is used as an illicit substance responsible for the most common cause of drug-related death. It is a stimulant that acts on the sympathetic nervous system and cardiovascular system leading to exaggerated, prolonged sympathetic activity due to the accumulation of neurotransmitters. Cardiovascular side effects of cocaine are coronary artery spasms, myocarditis, arrhythmias, and congestive heart failure. Takotsubo cardiomyopathy (TCM) is characterized by transient hypokinesis, akinesis, or dyskinesis of the left ventricle (LV) wall with or without apical involvement in the absence of obstructive coronary artery disease. Cocaine-induced TCM is an extremely rare condition emphasizing the need of its prompt diagnosis by the physicians. We present a case report of a 54-year-old male, brought to the emergency department (ED) after an out-of-hospital cardiac arrest (CA), found to have TCM in the setting of cocaine use. Clinicians need to understand the association between cocaine use and the development of TCM as cardiomyopathy of this type can result in complete remission after discontinuing the offending agent.

Observational Study of Thrombotic Events in a Random Cohort of Hospitalized COVID-19 Patients at a Community-Based Hospital of New York City During the Beginning of the 2020 Pandemic.

Coronavirus disease 2019 (COVID-19) continues to pose an unprecedented challenge for the entire world and the healthcare system. Different theories have been proposed elucidating the pathophysiological mechanisms attributing to high mortality and morbidity in COVID-19 infection. Out of them, thrombosis and procoagulant state have managed to earn the maximum limelight. We conducted an observational study based on data from randomly selected 349 hospitalized patients with COVID-19 infection in a community-based hospital in New York City during the first wave of the COVID-19 viral surge in March 2020. The main objective of our study was to assess the risk and occurrence of thrombotic events (both venous and arterial) among the hospitalized patients including the intensive care unit (ICU) and non-ICU admissions with confirmed COVID-19 infection. The primary outcome in our study was defined as the thrombotic events that included myocardial infarction (MI), deep venous thrombosis (DVT), cerebrovascular accidents (CVA), and pulmonary embolism (PE). The study correlated the association of thrombotic events with the level of biomarkers of interest: D-dimer >1000 ng/ml, troponin-I >1 ng/ml, or both. The association of D-dimers and troponin-I with thrombotic events was measured using both univariate and multivariate Cox proportional hazard (PH) regression analysis. Out of a total of 349 patients, 78 patients (22.35%) were found to have elevated biomarkers (D-dimer >1000 ng/ml and/or troponin-I >1 ng/ml) and were categorized as a high-risk group. Eighty-nine patients developed thrombotic complications (evidence of more than one thrombotic event was found in several patients). Two-hundred seventy-one (77.65%) patients had no documentation of thrombosis. The incidence of thrombotic events included myocardial infarction (MI; N=45; 12.8%), cerebrovascular accidents (CVA; N=16; 4.5%), deep venous thrombosis (DVT; N=16; 4.5%), and pulmonary embolism (PE; N=9; 2.57%).

Idiopathic thrombocytopenia with iron deficiency anemia.

We report a rare case of anemia and thrombocytopenia as a result of uterine fibroid and adenomyosis, complicated by immune thrombocytopenic purpura (ITP). Symptoms were presented as menorrhagia and metrorrhagia in a 34-year-old African American woman, who was later treated with blood and platelet transfusion and iron therapy with steroids. Uterine fibroids are commonly found to cause hematologic disturbances such as anemia and reactive thrombocytosis and, less commonly, thrombocytopenia. Moreover, such hematologic disturbances are secondary to heavy and irregular uterine bleeding, which is typically presented. A previous uterine fibroid diagnosis was made and reconfirmed by pelvic and transvaginal ultrasound to exclude other locoregional pathologies. ITP was suggested by Coombs test and several other serologies, leading to confirmation via bone marrow biopsy. In a previous case study, we reported positive responses in hemotecrit and platelet count after the introduction of iron therapy to an iron-depleted middle-aged female presenting severe anemia and thrombocytopenia.1.

Triad of iron deficiency anemia, severe thrombocytopenia and menorrhagia-a case report and literature review.

INTRODUCTION: Thrombocytosis is a common disorder in patients diagnosed with iron deficiency anemia. The decreased platelet counts commonly found iron deficiency anemia is rarely reported in clinical practice. The exact mechanism of the occurrence of thrombocytopenia in iron deficiency anemia remains unclear. In this case report we discuss a triad of symptoms seen in the African American population: Iron deficiency anemia, menorrhagia and thrombocytopenia. CASE PRESENTATION: A 40 year old multiparous African-American woman presented with heavy vaginal bleed, severe anemia (3.5 g/dL) and thrombocytopenia (30,000/mm(3)). The peripheral blood smear showed marked microcytic hypochromic cells with decreased platelets counts. After excluding other causes of thrombocytopenia and anemia, increased red cell distribution width and low iron saturation confirmed the diagnosis of iron deficiency anemia. Treatment for iron deficiency anemia was initiated with intravenous and oral iron supplements. Two months following treatment of iron deficiency anemia, the triad of manifestations resolved and patient remained stable. CONCLUSION: Profound degree of iron deficiency anemia can present with thrombocytopenia and severe menorrhagia. Iron replacement should be the main treatment goal in these patients. This case report further supports the 2 compartment model of the role of iron in maintaining platelet counts.
