Coronavirus disease 2019 (COVID-19) has been labeled a global pandemic with the first reported case of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) occurring in Wuhan, China in December 2019. To combat the alarming, increasing rate of those affected by the virus, vaccine development ensued. As mass vaccination initiatives against COVID-19 ensued, adverse reactions began emerging. This non-consecutive, population-based case series focuses on four vaccine-associated neurological adverse events across the central and peripheral nervous system detailing the diagnosis, treatment and subsequent follow-up management. These four patients presented to public and private hospitals in Trinidad and Tobago with new-onset neurological diseases soon after their first doses of a COVID-19 vaccine: two after the Pfizer-BioNTech vaccine (one case of new-onset seizures and one case of longitudinally extensive transverse myelitis) and two after the ChAdOx1 nCoV-19 vaccine (one case of Guillain-Barre syndrome and one case of meningitis-retention syndrome). The background incidence rates of neurological conditions in the population and the large numbers of persons being vaccinated means that some of these conditions will appear in the post-vaccination window by chance. Hence, establishing causal links is difficult. The close temporal relationship between vaccination and the presenting symptoms, the biological plausibility, and the extensive diagnostic workup to exclude other causes fulfill criteria provided by the World Health Organization for causality assessment of an adverse event following immunization on an individual level. On this basis, it was determined that these adverse events were likely due to the vaccines. However, establishing causal links on a population level requires large epidemiological studies and cannot be done on individual case reports alone. While physicians should be cognizant of even these rare adverse events of vaccines, it should be reiterated that the overall safety profile of vaccines is well established.
Facet joint violation occurred in just >30% of the patients and 20% of the screws in this study. This, therefore, raises the theoretical possibility of long-term deterioration in the clinical results following the use of transpedicular instrumentation.
Objectives We sought to determine the baseline demographic and clinical characteristics of patients with Chronic Venous Disease (CVD) across the Caribbean, and to evaluate patients’ compliance to conservative therapy and the effectiveness of such therapy in reducing patients’ CVD symptoms. Method Patients were enrolled into the VEIN Act Program, and their demographic data, CVD symptoms (and their intensity) and CEAP C-classification was recorded at the first visit. Patients were prescribed conservative therapy, and symptom intensity and patient compliance and satisfaction evaluated at a follow-up visit. Results We enrolled 193 patients into the study, most of which (76%) were female, between 39–78 years (80%) and within the C2-C4a classes (56.1%). Pain (61.1%) and heaviness (58.5%) were the most common symptoms. Patient compliance to the prescribed treatment was relatively high for all modalities (>75%) and most patients (92.1%) were at least somewhat satisfied with their treatment. Conclusions Patient compliance to conservative therapy for management of CVD is high across the Caribbean, and such therapy is effective in reducing intensity of CVD symptoms.
The interaction between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and autoimmune thyroid disease is an emerging phenomenon. The present study describes the case of a 28-year-old female who experienced a relapse of Graves' disease following SARS-CoV-2 infection. She was biochemically euthyroid for 2 years prior to COVID-19 infection. However, she began experiencing palpitations, increased sweating and tremors of the hands 9 days after being diagnosed with COVID-19-related pneumonia. In addition to presenting this case, a comparison is made of this case to similar reports and the possible mechanisms underlying the association between SARS-CoV-2 and Graves' disease are discussed. One is a direct result of viral uptake by thyroid cells, while another is a result of the hyperinflammatory ʻcytokine storm' and its effects on the hypothalamic-pituitary-thyroid axis and T-cell immunity.
We describe the case of an 82-year-old female referred to the vascular clinic for further evaluation and management of suspected inferior vena cava (IVC) thrombosis. She had previously presented to the general practitioner with a one-week history of vague abdominal pain in the right and left loins. Contrast-enhanced magnetic resonance imaging (MRI) of the abdomen and magnetic resonance angiography/magnetic resonance venography (MRA/MRV) revealed a 10 cm filling defect in the IVC, with the inferior margin of ≈5.8 cm proximal to the aortic bifurcation and its superior margin in the intrahepatic portion of the IVC. The filling defect had a transverse diameter of 2.6 cm and displayed heterogenous enhancement with contrast.We performed an endovascular biopsy with fluoroscopy (anteroposterior {AP} and lateral views) being utilized throughout the procedure to locate the mass and position the forceps in the tumor bed. The IVC was accessed via the right common femoral vein with a 10F catheter sheath. The sheath was advanced using the Seldinger technique to within ≈1 cm of the mass; then, a biopsy forceps (Micro-Tech single-use 8.5 mm biopsy forceps, Nanjing, China) was inserted, and six tissue samples were obtained.We report this case to add to the growing evidence that endovascular biopsy of IVC tumors can be performed safely and effectively.
