COVID-19 and catatonia: Prevalence, challenges, pathophysiology, and treatment.

BACKGROUND: Emerging literature supports the association between acute COVID-19 infection and neuropsychiatric complications. This article reviews the evidence for catatonia as a potential neuropsychiatric sequela of COVID-19 infection. METHODS: PubMed was searched using the terms catatonia, severe acute respiratory syndrome coronavirus 2, and COVID-19. Articles were limited to those published in the English language between 2020 and 2022. Forty-five articles that specifically studied catatonia associated with acute COVID-19 infection were screened. RESULTS: Overall, 30% of patients with severe COVID-19 infection developed psychiatric symptoms. We found 41 cases of COVID-19 and catatonia, with clinical presentations that varied in onset, duration, and severity. One death was reported in a case of catatonia. Cases were reported in patients with and without a known psychiatric history. Lorazepam was successfully used, along with electroconvulsive therapy, antipsychotics, and other treatments. CONCLUSIONS: Greater recognition and treatment of catatonia in individuals with COVID-19 infection is warranted. Clinicians should be familiar with recognizing catatonia as a potential outcome of COVID-19 infection. Early detection and appropriate treatment are likely to lead to better outcomes.

Resolution of status epilepticus after ketamine administration.

BACKGROUND: Status Epilepticus is the most common non-traumatic neurologic emergency in childhood. Current algorithms prioritize the use of benzodiazepines as first line treatment followed by Levetiracetam or Valproic Acid, possibly Fosphenytoin and eventually high dose Propofol and intubation. CASE REPORT: A 9-month old girl was brought to the emergency department with a continuous seizure involving the right upper and lower extremity for 45 min prior to arrival. Patient received a dose of rectal Diazepam, intramuscular Midazolam, 2 doses of Lorazepam, Levetiracetam, Fosphenytoin and 2 additional doses of Lorazepam. The seizure remained refractory and generalized. In anticipation of intubation, and because of its action on the NMDA receptor, Ketamine (1 mg/kg IV) was administered. The clonic movements and eye deviations stopped. Patient was intubated for airway protection, sedated with Propofol, then admitted to the PICU. EEG showed no evidence of a seizure pattern. Labs (CBC, CMP, COVID) were unremarkable except for WBC 24.5, blood glucose of 346 and CO2 of 17 with normal anion gap. Urinalysis showed a urinary tract infection. Patient was at her baseline on 1 week post-discharge re-evaluation. Ketamine theoretically may abort seizures through blockade of NMDA receptors which are unregulated in status epilepticus. To date, no randomized controlled trials have been reported. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Ketamine may have a role in treating status epilepticus. It may be considered for induction for rapid sequence intubation and possibly as a third or fourth line agent in refractory cases.

Acute COVID-19 Infection Associated With Necrotizing Disseminated Acute Leukoencephalopathy and Brain Microhemorrhages in a Pediatric Patient.

We present a case of a 14-year-old, previously healthy female, admitted with acute coronavirus disease 2019 infection and new-onset seizures secondary to virus-associated necrotizing disseminated acute leukoencephalopathy. Her symptoms resolved completely with intravenous immunoglobulin and steroids. Pathophysiology and prognosis of neurologic manifestations of coronavirus disease 2019 remain unclear.

Brief psychotic disorder with delusion content related to the COVID-19 outbreak.

The COVID-19 outbreak has affected millions of people globally and it also has a huge psychological impact. The objective of this case report is to outline the possible effect of the COVID-19 pandemic to the content of delusions in patients with psychosis. Α 34-year-old male with no history of mental disorder, involuntarily hospitalized due to agitation and aggression towards others, experienced grandiose delusions, referential delusions and delusions of passivity. The content of all his delusions was related to the COVID-19 pandemic. His symptoms were not proven to be caused by any physical condition or substance use disorder. He was prescribed olanzapine 10mg bd and lorazepam 2,5mg td and demonstrated significant improvement with a complete subsidence of his symptoms within a week. He was discharged after a total of 13 days with an ICD-10 diagnosis of brief psychotic disorder. At his 6 months follow-up, he reported no psychiatric symptoms. Existing literature indicates a strong relationship between life experiences and the content of delusions. This case report highlights how the stressful life event of the COVID-19 outbreak affected the content of our patient's delusions.

Neurocovid: Pharmacological Recommendations for Delirium Associated With COVID-19.

BACKGROUND: The pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged as one of the biggest health threats of our generation. A significant portion of patients are presenting with delirium and neuropsychiatric sequelae of the disease. Unique examination findings and responses to treatment have been identified. OBJECTIVE: In this article, we seek to provide pharmacologic and treatment recommendations specific to delirium in patients with COVID-19. METHODS: We performed a literature search reviewing the neuropsychiatric complications and treatments in prior coronavirus epidemics including Middle Eastern respiratory syndrome and severe acute respiratory syndrome coronaviruses, as well as the emerging literature regarding COVID-19. We also convened a work group of consultation-liaison psychiatrists actively managing patients with COVID-19 in our hospital. Finally, we synthesized these findings to provide preliminary pharmacologic recommendations for treating delirium in these patients. RESULTS: Delirium is frequently found in patients who test positive for COVID-19, even in the absence of respiratory symptoms. There appears to be a higher rate of agitation, myoclonus, abulia, and alogia. No data are currently available on the treatment of delirium in patients with COVID-19. Extrapolating from general delirium treatment, Middle Eastern respiratory syndrome/severe acute respiratory syndrome case reports, and our experience, preliminary recommendations for pharmacologic management have been assembled. CONCLUSIONS: COVID-19 is associated with neuropsychiatric symptoms. Low-potency neuroleptics and alpha-2 adrenergic agents may be especially useful in this setting. Further research into the pathophysiology of COVID-19 will be key in developing more targeted treatment guidelines.

Paracervical blocks facilitate timely brachytherapy amidst COVID-19.

PURPOSE: The COVID-19 pandemic presents serious challenges for brachytherapists, and in the time-sensitive case of locally advanced cervical cancer, the need for curative brachytherapy (BT) is critical for survival. Given the high-volume of locally advanced cervical cancer in our safety-net hospital, we developed a strategy in close collaboration with our gynecology oncology and anesthesia colleagues to allow for completely clinic-based intracavitary brachytherapy (ICBT). METHODS AND MATERIALS: This technical report will highlight our experience with the use of paracervical blocks (PCBs) and oral multimodal analgesia (MMA) for appropriately selected cervical ICBT cases, allowing for completely clinic-based treatment. RESULTS: 18 of 19 (95%) screened patients were eligible for in-clinic ICBT. The excluded patient had significant vaginal fibrosis. 38 of 39 intracavitary implants were successfully transitioned for entirely in-clinic treatment utilizing PCBs and oral MMA (97% success rate). One case was aborted due to inadequate analgesia secondary to a significantly delayed case start time (PO medication effect diminished). 95% of patients reported no pain at the conclusion of the procedure. The median (IQR) D2cc for rectum and bladder were 64.8 (58.6-70.2) Gy and 84.1 (70.9-89.4) Gy, respectively. Median (IQR) CTV high-risk D90 was 88.0 (85.6-89.8) Gy. CONCLUSIONS: In a multidisciplinary effort, we have successfully transitioned many ICBT cases to the clinic with the use of PCB local anesthesia and oral multimodality therapy in direct response to the current pandemic, thereby mitigating exposure risk to patients and staff as well as reducing overall health care burden.
