Babesiosis is a blood-borne disease found mainly in the United States caused by a parasitic piroplasm. While most infections are mild to moderate in immunocompetent hosts, life-threatening complications can occur in those with significant comorbidities like congestive heart failure (CHF) or chronic obstructive pulmonary disease (COPD). There is sparse literature discussing the complications of Babesia microti infection or the pathophysiology and management thereof. find more A literature review was conducted to consolidate the current knowledge about the disease, pathophysiology, and proposed management of all potential complications based on risk factors and other clinical information. A MeSH cross-references strategy was employed in PubMed using the search terms "babesia" and "babesiosis" and the established associated conditions, and the search expanded to increase capture. Only papers written in the English language and discussing human subjects in the North American patient population were included. The initial search yielded 315 papers and, after applying the inclusion/exclusion criteria, a final number of 18 was reviewed. The various complications and pathophysiology thereof are then discussed according to organ system. Babesia is a subversive parasite associated with a variety of conditions. We hope a better appreciation of all potential presentations and complications will help clinicians manage this increasingly common zoonosis and reduce adverse effects. More research is recommended into the pathophysiology and prevention of complications following this and other tick-borne illnesses.Coronary artery fistulas are an uncommon anatomic anomaly with variable presentations. We present an asymptomatic seven-month-old black male with a large coronary artery fistula draining into the right ventricle, causing an aortic backflow on diastole. Despite this prominent alternative drainage pathway, coronary fistulas are commonly an incidental finding and, as in this case, may not require intervention. Through an assessment of previous literature, we recommend providers maintain an elevated index of suspicion for coronary artery fistulas in young persons who present with signs of heart failure, and that the decision to treat should be determined based on the patient's symptoms, age at presentation, and imaging finding severity.Bupropion hydrochloride is a norepinephrine-dopamine reuptake inhibitor approved for the treatment of depression and smoking cessation. Although cardiovascular and hematological side effects are common with bupropion along with weight loss and headache, hematological side effects are rarely reported other than few post marketing studies. Here we present the case of a 47-year-old white female who presented with significant leukocytosis after bupropion overdose.Traumatic diaphragmatic rupture is uncommon, life threatening and remains a diagnostic and radiographic challenge. Diagnosis is frequently delayed, which may result in a late intervention with a potential catastrophic outcome. We report a case of an acute diaphragmatic laceration in a 40-year-old woman, with a personal history of bipolar disease, admitted on the emergency department after falling from a nine-meter building. During initial evaluation, the plain chest radiograph showed multiple rib fractures associated with a significant left pneumothorax. It also showed an elevated left diaphragm with a suspicious gastric shadow in the left hemithorax. Computed tomography confirmed the diagnosis of a left-sided diaphragmatic laceration and the patient was advised surgical intervention. During laparoscopy, a 7 cm rupture of the left hemi-diaphragm with herniation of the stomach was identified. The hernia was reduced laparoscopically and the defect repaired with interrupted, non-absorbable, sutures. The patient had an uneventful recovery and remained well at a 3-month follow-up visit. Emergency repair of the diaphragm is usually performed via a thoracotomy or/and laparotomy. However, if the patient is hemodynamically stable and major organ injuries have been excluded, a laparoscopic approach can be considered safe and effective.Introduction The polyaxial head pedicle screw-rod system is a commonly used spinal instrumentation technique to achieve stabilization, deformity correction, and bony fusion. We present a novel plate-based pedicle screw system (UNIMAXTM) that can be used for multi-level instrumentation with potential advantages for selected applications. Methods Bilateral titanium monoaxial pedicle screws are linked at each level by robust transversely oriented cross plates forming ring constructs capable of rigid triangulation at each level. The cross plates are then interconnected by sagittally oriented rigid plates situated medial to the screw heads. Biomechanically, the construct was tested for quasi-static torsion and fatigue in axial compression. The system is approved by the Food and Drug Administration (FDA). The system and case examples are presented showing its potential advantages. Results The quasi-static torsion, the mean for the angular displacement, torsional stiffness, and torsional ultimate strength was 2.5 degrees (SD ± 0.8), 5.3 N-m/mm (SD ± 0.7), and 21.6 N-m (SD ± 4.4). For the fatigue in axial compression, the closed ring construct failed when the applied load and bending moment were ≥ 1500 N and ≥ 60 N.m. This system maximizes the construct rigidity, allows easy extension to adjacent levels, and can be incorporated intuitively into practice. The ring construct with triangulation at each level, together with its biomechanical robustness, predicts a high pullout resistance. It requires an open posterior approach incompatible with minimally invasive techniques. Conclusion This system may have advantages over the screw-rod systems in carefully selected situations requiring extra rigidity and high pull-out strength for complex reconstructions, sagittal and/or coronal correction, patients with poor bone quality, revisions, and/or extension to adjacent levels.Introduction While coronavirus disease 2019 (COVID-19) mostly causes respiratory illnesses, emerging evidence has shown that patients with severe COVID-19 can develop complications like venous thromboembolism (VTE) and arterial thrombosis as well. The incidence of thrombosis among critically ill patients in the literature has been highly variable, ranging from 25 to 69%. Similarly, reported mortality among critically ill patients has been highly variable too, and it has ranged from 30 to 97%. In this study, we analyzed data from a large database to address the incidence, the risk factors leading to thrombotic complications, and mortality rates among COVID-19 patients. Material and methods Data were obtained from TriNetX (TriNetX, Inc., Cambridge, MA), a multinational clinical research platform that collects medical records from 42 healthcare organizations (HCOs). All nominal data were compared using the chi-squared test. Alpha of less then 0.05 was considered statistically significant. We used Benjamini-Hochberg correction with a false discovery rate of 0.
