We report a case of encephalitis in a young male patient with severe coronavirus disease 2019 (COVID-19) who initially presented with typical symptoms of fever, dry cough, and shortness of breath but later on developed acute respiratory distress syndrome and required mechanical ventilation. Two days post-extubation, the patient developed new-onset generalized tonic-clonic seizures and confusion. MRI of the brain was done and it showed an abnormal signal in the bilateral medial cortical frontal region. His cerebral spinal fluid (CSF) analysis revealed a characteristic picture of a viral infection with a high white blood cell count and normal glucose and protein levels. After ruling out all common causes of viral encephalitis such as herpes simplex virus (HSV) and based on the review of available literature regarding the neurological manifestations of COVID-19, this case was labeled as acute viral encephalitis secondary to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Myasthenia gravis is an auto-immune disease that results in muscle weakness caused by antibodies released against acetylcholine receptors at the presynaptic membrane. Treatment options include acetylcholinesterase medications that cause a wide range of side-effects by increasing the concentration of acetylcholine at the synaptic cleft. One peculiar side effect seen is the precipitation of myocardial infarction caused by an excess of acetylcholine especially among elderly females. We present an interesting case of an 88-year-old female with a history of lung cancer newly diagnosed with paraneoplastic myasthenia gravis, started on treatment with prednisone 40 mg daily, and pyridostigmine 60 mg every six hours. She initially showed remarkable improvement in symptoms within a few hours, however, one day later, the patient developed sudden onset of chest pain radiating towards her left arm. A 12-lead electrocardiogram (EKG) showed diffuse ST-elevation in anterior leads and cardiac enzymes were found to be elevated. Pyridostigmine was stopped and the patient was started on heparin. The patient underwent cardiac catheterization which showed 50% stenosis in the right coronary artery (RCA) and 70% in the left anterior descending artery (LAD). The patient was monitored in the cardiac care unit (CCU) for 24 hours and later on discharged home on oral prednisone. It is a common practice to start treatment with anti-cholinesterase medications in newly diagnosed patients of myasthenia gravis, however, these medications can precipitate myocardial ischemia by coronary vasogenic spasm or by their arrhythmogenic effect. It is important to be aware of these outcomes while starting patients on these medications.
Clinical rationale for study: Despite advancements in critical care, the mortality rate of sepsis remains high, with an overall poor prognosis. There is a complex pathophysiology of a lethal cascade of cytokines and inflammatory proteins underlying sepsis. The use of vitamin C can theoretically suppress the inflammatory cascade but remains a questionable practice due to a lack of conclusive evidence. Aims of the study: To appraise the therapeutic role of vitamin C in sepsis. Materials and methods: A systematic review was conducted on PubMed, Embase, and the Central Cochrane Registry. The study included randomized clinical trials (RCTs) with vitamin C as an intervention arm in the septic patient population. For continuous variables, the difference in means (MD) and for discrete variables, the odds ratio (OR) was used. For effect sizes, a confidence interval of 95% was used. A p-value of less than 0.05 was used for statistical significance. The analysis was performed using a random-effects model irrespective of heterogeneity. Heterogeneity was evaluated using the I2 statistic. Results: 23 studies were included with the total sample size of 2712 patients. In patients treated with vitamin C, there was a statistically significant reduction in the mortality: OR = 0.778 (0.635 to 0.954), p = 0.016; the sequential organ failure assessment score (SOFA): MD = −0.749 (−1.115 to −0.383), p < 0.001; and the duration of vasopressor requirement: MD = −1.034 days (−1.622 to −0.445), p = 0.001. No significant difference was found in the hospital or ICU length of stay. Conclusions and clinical implications: Vitamin C treatment regimens were associated with reduced mortality, SOFA score, and vasopressor requirement compared to the control in sepsis. Given its low cost and minimal adverse effects, we strongly encourage further large, randomized trials to establish vitamin C as a standard of care in sepsis management.
Epstein Barr Virus (EBV) is one of the herpes viruses that is responsible for causing infectious mononucleosis, lymphomas, and carcinomas primarily in immunocompromised individuals. We present a case of EBV-induced pneumonitis in an immunocompetent female, successfully treated with steroids. The patient is a 70 year-old female with a history of infectious mononucleosis in her teens who presented to the emergency room with worsening shortness of breath, associated with cough and fever. She underwent extensive work up and her serologic workup revealed positive anti-EBV antibodies, pointing towards the diagnosis of EBV induced pneumonitis. EBV-induced Pneumonitis is a very rare entity and is especially hardly seen among immunocompetent individuals. This interesting case shows that in this new era of viral pneumonias, EBV induced pneumonitis should be considered among differentials when dealing with lung infections. Prompt initiation of treatment with steroids or antiviral medication may result in complete recovery. The choices among treatment options can be individualized according to the severity of disease, course of disease progression, and side effect profile of medications. In our case we were able to successfully treat the patient with high dose steroids only.
Lung cancer is one of the most common cancers diagnosed every year and accounts for a major percentage of cancer incidence and mortality annually, especially in men. Lung adenocarcinoma is a subtype of nonsmall cell lung cancer (NSCLC), which is the most common type of lung cancer found in smokers and nonsmokers alike. It is known to have diverse CT chest findings ranging from: ground-glass opacities (GGOs) with partially solid nodules, to single or multiple solid nodules that can be either central or peripheral, to thin-walled cystic lesions. Lesions are usually solitary but may be multifocal. Rarely, these lesions can be calcified or demonstrate cavitation, which can make it difficult to distinguish from an infectious disease like tuberculosis, pneumonia, or even fungal infections. Here, we present a case of a 36year-old Asian male with no significant past medical history, except a 16-pack-year smoking history and recent deployment to Afghanistan, that initially presented with a chief complaint of cough of threeweek duration. His CT scan showed innumerable bilateral pulmonary nodules within both lung fields with a miliary type appearance that ultimately turned out to be adenocarcinoma.
Esophageal stent placement is used to treat benign strictures, esophageal perforations, fistulas and for palliative therapy of esophageal cancer. Although it is a safe and effective method, complications are increasing the morbidity and mortality rate. Small bowel perforation as a result of esophageal stent migration is a remarkably rare occurrence. We report one case from our clinical experience and undertake a review of the previously reported cases retrieved from the PubMed. A total of six cases were found accessible. Abdominal pain was the common clinical presentation. The mean time from stent placement to perforation was 3.4 months (range, two weeks to 12 months). The jejunum was the frequently perforated portion of the small bowel. Surgical intervention was the mainstay of treatment. This comparative review illustrates that clinicians should remain vigilant for small bowel perforation in patients with esophageal stent placement. Further studies are required to delineate the magnitude and scope of this association.
Coronavirus disease 2019 (COVID-19), apart from commonly involving the respiratory system, has its impact on the central nervous system, with a wide spectrum of clinical presentations ranging from headaches to ischemic strokes. The ongoing research regarding this novel disease has found that there is a very high prevalence of thrombotic episodes especially in critically ill patients when compared to severe presentation of other viral illnesses. This COVID-19-associated coagulopathy has a very complex etiology with the ability to form thrombus in arteries, veins, and microvasculatures of different organs. We present a unique case of a young woman with underlying COVID-19 who unfortunately developed locked-in syndrome due to bilateral pontine infarction during the course of her illness.
