ABSTRACT
History: Transient and generalized adverse effects are common following COVID-19 vaccination;among other adverse effects, shoulder injuries related to vaccine administration (SIRVA) have been known to occur. In this case, a previously healthy right-hand dominant 62-year-old male presented with left shoulder pain and weakness 3 months after receiving a COVID-19 intramuscular vaccine in the left deltoid. Approximately 2 weeks after the injection, he started experiencing pain and numbness around the injection site along with ipsilateral shoulder weakness. Despite conservative management with Motrin, Medrol Dosepak, gabapentin and physical therapy (PT), the pain and weakness persisted. Physical Exam: Left Shoulder-No calor or erythema;significant atrophy of the anterior and middle deltoid muscle relative to right side;abduction 4/5;external rotation with shoulder adducted 4/5;range of motion for active forward flexion was 150 degrees and passive was 170 degrees;passive range of motion for external rotation was 70 degrees;internal rotation to the level of L5;sensation to light touch was intact. Right Shoulder-Range of motion, strength, and sensation were intact. Cervical Spine-Full ROM;no cervical paraspinal tenderness noted. Negative Spurling's and Lhermitte's tests. Differential Diagnosis: 161. Axillary Nerve Palsy 2/2 Chemical Neurotoxicity 162. Brachial Neuritis 163. Mechanical Axillary Nerve Palsy 2/2 Vaccination 164. Partial-Tear of Left Supraspinatus Tendon 165. Acromioclavicular Osteoarthritis Test Results: Left Shoulder-XR:Mild pseudo-subluxation;MRI w/o contrast: 8x9mmpartial-thickness articular surface tear of the distal supraspinatus tendon (<50%fiber thickness). Minimal subacromial bursitis. Mild acromioclavicular joint osteoarthritis. EMG/NCV: Left and Right Axillary Motor Nerves: prolonged distal onset latency;Left Deltoid: increased insertion activity, moderately increased spontaneous activity, reduced recruitment;Remaining LUE muscles without evidence of electrical instability Final Diagnosis: Axillary Nerve Palsy Secondary To Chemical Neurotoxicity from Intramuscular COVID-19 Vaccine. Discussion(s): We postulate that the neurologic deficits presented in our case may be attributed to chemical neurotoxicity to the axillary nerve following vaccination as the delayed onset of pain and weakness are most consistent with this differential. There are several cases of brachial neuritis following vaccination for the prevention of COVID- 19, however, EMG/NCV results in our patient were not consistent with brachial plexopathy. Additionally, while there have been a handful of reported cases of bursitis following COVID-19 vaccines falling under the SIRVA classification of injuries, this is the first case of reported axillary nerve neurapraxia. Outcome(s): The patient's left shoulder numbness and pain improved with PT and medical management. While mild improvement in strength was noted, weakness and atrophy persisted even on the third follow up visit 6 months after the initial appointment. He was counseled on his injury and was recommended to undergo repeat EMG testing to document recovery after his 6-month follow-up appointment. Follow-Up: The patient did not follow-up for a repeatEMG after his 6-month follow-up appointment. At that time, the patient was clinically stable, tolerating PT, and expecting recovery of his deltoid function.
ABSTRACT
A 5-month-old, intact male, yellow Labrador retriever was presented with a 24-hour history of anorexia and vomiting. Abdominal imaging revealed the presence of a mechanical obstruction in the jejunum and peritoneal effusion. Cytologic evaluation and culture of the effusion prior to surgery identified a suppurative exudate with bacteria consistent with septic peritonitis and suspected to be related to the intestinal lesion. An exploratory laparotomy was performed, and a segment of jejunum was circumferentially severely constricted by an off-white, fibrous band of tissue. Resection and anastomosis of the strangulated segment of jejunum and excision of the constricting band provided resolution of the clinical signs. The dog made a complete recovery. Histologic evaluation revealed the band to be composed of fibrovascular and smooth muscle tissue, consistent with an idiopathic anomalous congenital band. No other gastrointestinal lesions were observed, either grossly at surgery or histologically in the resected segment of intestine. To our knowledge, a similar structure has not been reported in the veterinary literature.Copyright © 2022 Canadian Veterinary Medical Association. All rights reserved.
ABSTRACT
In 2019, a new virus-A novel virus, COVID-19, bought disaster across the globe. The people were in great panic, death tolls crossed millions in number. Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus. It is a debilitating disease-causing post covid effects too. Many of the cases have not yet recovered from the after effects of the disease. Many of the patients recovered instantaneously without any treatment, whereas many lost their lives. There was a chaos in all the countries across the globe. The patients recovered with the help of proper treatment and were back to their schedule and lifestyle. After, one year from the recovery, few patients started coming up with muscular fatigue, neurological deficits such as tingling in lower limbs, sharp shooting pain travelling throughout the legs. The patient seek treatment for Sciatica or any other nerve suppling the lower limb. The clinical features were misguiding and confused the clinicians. Some diagnosed it as PIVD, few others were confused with compressed and inflamed muscles. The diagnostic tests, including Haematological tests, MRI, CT-Scan, all went in vain.Later, the haematological tests for COVID-19 antibodies and other tests helped in coming up to a conclusion and start with subsequent treatment.This article focuses on the neuropathy and treatment of the same.Copyright © 2022, Anka Publishers.

ABSTRACT
Background: The potential of continuous cough monitoring is in an early stage, while almost every other clinical symptom has a way to be objectively monitored. Objective(s): Study if continuous cough monitoring is useful for early notice of an onset or worsening of respiratory conditions. Method(s): A free mobile application was used to detect and record cough sounds. Only 0.5s snippets of explosive sounds are sent to the server for AI to analyse. The 3 cases presented were identified within a study in Navarra, Spain. Result(s): Case 1: a 56-year-old was using the app with an average of 600 coughs/d, unknown cause. A trial with gabapentin was started, which within a month resulted in 150 coughs/d. With omeprazole added, coughing reduced to ~50 coughs/d. Case 2: a 70-year-old smoker was using the app with an average 52 coughs/day in over 2 months. She quit smoking and noticed improvements in cough, app showing 12 coughs/d. The next month, smoking relapsed, reaching 34 coughs/d. Data dynamics renewed her motivation to quit. Case 3: a 35-year-old was using the app at night, with an average of 4 coughs/hr (not self-perceived). Suddently, the patient felt general malaise and the app detected 12 coughs/hr (not self-perceived). Next day, she received a diagnosis of uncomplicated COVID-19. Conclusion(s): Cough patterns correlate with clinical progress and perceived improvement, accurately indicate signs of smoking cessation and relapse.
ABSTRACT
This article summarizes the top 20 research studies of 2021 identified as POEMs (patient-oriented evidence that matters) that did not address the COVID-19 pandemic. Sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists prevent adverse cardiovascular and renal outcomes in patients with type 2 diabetes mellitus and also reduce all-cause and cardiovascular mortality. Most older adults (mean age, 75 years) with prediabetes do not progress to diabetes. Among patients in this age group with type 2 diabetes treated with medication, an A1C level of less than 7% is associated with increased risk of hospitalization for hypoglycemia, especially when using a sulfonylurea or insulin. For patients with chronic low back pain, exercise, nonsteroidal anti-inflammatory drugs, duloxetine, and opioids were shown to be more effective than control in achieving a 30% reduction in pain, but self-discontinuation of duloxetine and opioids was common. There is no clinically important difference between muscle relaxants and placebo in the treatment of nonspecific low back pain. In patients with chronic pain, low- to moderate-quality evidence supports exercise, yoga, massage, and mindfulness-based stress reduction. For acute musculoskeletal pain, acetaminophen, 1,000 mg, plus ibuprofen, 400 mg, without an opioid is a good option. Regarding screening for colorectal cancer, trial evidence supports performing fecal immunochemical testing every other year. For chronic constipation, evidence supports polyethylene glycol, senna, fiber supplements, magnesium-based products, and fruit-based products. The following abdominal symptoms carry a greater than 3% risk of cancer or inflammatory bowel disease: dysphagia or change in bowel habits in men;rectal bleeding in women;and abdominal pain, change in bowel habits, or dyspepsia in men and women older than 60 years. For secondary prevention in those with established arteriosclerotic cardiovascular disease, 81 mg of aspirin daily appears to be effective. The Framingham Risk Score and the Pooled Cohort Equations both overestimate the risk of cardiovascular events. Over 12 years, no association between egg consumption and cardiovascular events was demonstrated. Gabapentin, pregabalin, duloxetine, and venlafaxine provide clinically meaningful improvements in chronic neuropathic pain. In patients with moderate to severe depression, initial titration above the minimum starting dose of antidepressants in the first eight weeks of treatment is not more likely to increase response. In adults with iron deficiency anemia, adding vitamin C to oral iron has no effect. In children with pharyngitis, rhinosinusitis, acute bronchitis, or acute otitis media, providing education combined with a take-and-hold antibiotic prescription results in 1 in 4 of those children eventually taking an antibiotic.Copyright © 2022 American Academy of Family Physicians.
ABSTRACT
Background/Aims Effective symptom management may require the use of medications. Medication adherence may be hindered by formulation aspects, such as poor taste. Paediatric studies indicate, that despite concerns of swallowing solid dose forms, children prefer these to liquid forms. They find the solid dose forms more palatable. However, swallowing numerous solid dose forms, may present a significant 'pill' burden to patients and their care-givers. Filling empty gelatine capsules with requisite medications is seen and used as a way to address palatability, decrease pill burden and thereby increase compliance. Yet there is little evidence on the impact this practise may have on the effectiveness of over-encapsulated medicines. This study explored the effect of over-encapsulation on in vitro disintegration and dissolution, of some commonly used medicines in paediatric palliative care. Method Immediate release (Cyclizine Hydrochloride, Gabapentin, Paracetamol) and modified release preparations (Omeprazole, Diclofenac sodium) were over-encapsulated in size 00 gelatin and HPMC capsules (n=6). Dissolution and disintegration were tested according to Pharmacopeia standards. Statistical analyses, using Student's T-test and f1 and f2 tests (respectively) were applied to determine similarities or differences in disintegration or dissolution. Results Disintegration and dissolution was prolonged for all over-encapsulated immediate release preparations, especially when using HPMC capsules. However, percentage of drug dissolved met the acceptance criteria for immediate-release solid oral dosage. Over-encapsulation of modified release preparations did not lead to significant dissolution or disintegration changes. Conclusion Over-encapsulation, may delay medication release, especially for immediate release medicines however, medicine effectiveness may not be. Further studies are required before we can safely recommend use of over-encapsulation as an administration compliance aid.
ABSTRACT
Background: Severe acute respiratory syndrome coronavirus 2 (SARS-COV2) infection has been associated with the development and persistence of various neurological symptoms in some patients. There have been few prior case reports of small fiber neuropathy (SFN) associated with this infection. However, literature is limited, and the etiology of these symptoms is unclear. Some reports suggested neuroinflammation. Objective(s): To present case series of 3 patients who developed small fiber neuropathy after SARS-COV2 infection. Method(s): We identified patients with SFN after SARSCOV2 infection from our neuromuscular database. We performed chart review and obtained clinical, demographic and, outcomes information of these patients. Result(s): The age of patients was 46, 56 and 71 years. Two female and one male. Time to neuropathy symptom evaluation in clinic from positive COVID19 test was 4 months, 6 months, and 10 months, respectively. None of the patients were hospitalized or given additional medications for COVID treatment. Patients 1& 3 had mild respiratory symptoms. Patient 2 had no symptoms, just a routine pre-op test was positive. All patients had numbness, tingling and painful paresthesias as the main symptoms. The second patient reported autonomic symptoms of heart racing and temperature dysregulation. Nerve conduction studies did not show large fiber peripheral neuropathy in any of the patients. Skin biopsy was performed at 7 months, 8 months and 13 months respectively post COVID infection and was positive in all 3 patients. There was no other etiology identified for the neuropathy Treatment included gabapentin for the first patient, the second patient received narcotic medication for a surgery and continued this for her neuropathic symptomsand the third patient is not on any medications for SFN. Conclusion(s): SFN can be associated with prior SARSCOV infection. There is need for further research to determine possible underlying neuropathological mechanisms and find effective treatments in COVID-related SFN.
ABSTRACT
SESSION TITLE: Issues After COVID-19 Vaccination Case Posters SESSION TYPE: Case Report Posters PRESENTED ON: 10/19/2022 12:45 pm - 01:45 pm INTRODUCTION: More reports are indicating a temporal association between Bell's palsy and the mRNA vaccine for coronavirus disease 2019 (COVID-19). Therefore, collecting vaccine history is becoming important in post-marketing surveillance to monitor the safety of vaccines in real-world settings. We report the case of concomitant occurrence of Bell's palsy and glossopharyngeal neuralgia leading to severe symptomatic hyponatremia in a previously healthy patient. CASE PRESENTATION: A 60 year-old-female without significant medical history presented to the hospital with odynophagia, and generalized weakness for two weeks. She decreased her oral intake due to stabbing pain in the back of her throat triggered by swallowing. She reported hyperacusis and frequent shooting pain in the left cheek managed with non-steroidal anti-inflammatory drugs. The symptoms occurred several days after the first dose of the mRNA vaccine for COVID-19. She denied previous COVID-19 infection and herpes zoster. Examination revealed dry mucosa, left facial muscle weakness, inability to raise the left eyebrow or lift the labial commissure, effacement of the nasolabial fold, and left-sided frontal wrinkles. Laboratory investigation revealed sodium of 110. Computerized Tomography of the brain revealed negative findings for intracranial abnormalities. Severe symptomatic hyponatremia was managed with hypertonic saline. The neurologist made the diagnosis of Bell's palsy and glossopharyngeal trigeminal neuralgia leading to poor oral intake. We initiated acyclovir, prednisone, and gabapentin. The patient recovered from hyponatremia and experienced improvement of neurological symptoms with initiated medications. DISCUSSION: High morbidity and mortality of patients with COVID-19 accelerated the development and production of the vaccines. During the pandemic, mRNA COVID-19 vaccines reduced asymptomatic and prevented severe symptomatic COVID-19 infection and its complications. Although the benefits and protective effects of the COVID-19 vaccines outweighed the risks associated with them, we have reports of associations between vaccines and certain disorders such as Bell's palsy. Glossopharyngeal neuralgia is defined as sudden severe brief pain in the distribution of the glossopharyngeal nerve. It can be described as transient stabbing pain experienced in the ear, tonsillar fossa, and base of the tongue. Unusual presentation is fear to eat as this can be a precipitating cause of the pain. It overlaps with trigeminal neuralgia and can create a diagnostic dilemma. CONCLUSIONS: In summary, it is unknown what causal relationship exists between the mRNA COVID-19 vaccine and neurological diseases such as Bell's palsy and glossopharyngeal neuralgia. Glossopharyngeal neuralgia is frequently overlooked as a diagnosis. This is a unique case of concomitant glossopharyngeal neuralgia and Bell's palsy that is coincidental with a history of COVID-19 vaccine. Reference #1: El Sahly HM, Baden LR, Essink B, et al.

ABSTRACT
Guillain-Barré syndrome (GBS) is an acute polyradiculoneuropathy. This is the first systematic clinical guideline, developed by an international task force using formal GRADE methodology. The diagnostic criteria remain primarily clinical, based on history and examination findings of acute progressive limb weakness and areflexia. Variants of GBS may include motor GBS, Miller Fisher Syndrome, and regional variants with weakness predominantly in lower limbs, face, or pharynx/neck/ arms. The differential diagnosis is wide. When uncertain, diagnosis may be assisted by nerve conduction tests, raised cerebrospinal fluid protein, and less often by MRI spine with contrast, or serum antibodies to gangliosides (especially for variants) or nodalparanodal antibodies (especially if not improving). Axonal versus demyelinating subtyping does not affect clinical management. A history of recent gastrointestinal or respiratory infection or of surgery may support the diagnosis. The risk of GBS is only very slightly increased after Covid-19 infection and after the adenovirus-vector vaccines to SARS-CoV2 (AstraZeneca or Johnson & Johnson) but not mRNA vaccines. Immune treatment is recommended with intravenous immunoglobulin or plasma exchange, for most patients except those mildly affected or after four weeks from onset. A repeat course is reasonable after a treatment-related fluctuation. Corticosteroids are not recommended. There is no evidence of benefi t from any other disease-modifying treatment. Respiratory function should be monitored by forced vital capacity and single breath count to assess the risk of needing mechanical ventilation, guided by the mEGRIS scale. Pain is very common. It may be musculoskeletal or neuropathic, and treated with gabapentin, tricyclic antidepressants or carbamazepine. Patients who fail to improve should be reassessed for the correct diagnosis and for axonal degeneration. Around 5% of patients with GBS may later develop CIDP but no test can reliably indicate this within the first eight weeks. Nodal-paranodal antibodies should be tested if CIDP is suspected or if the patient is not recovering well. The long-term outcome is less good in patients of older age, with preceding diarrhoea, or more severe weakness, as quantified by the mEGOS scale, and also in patients with smaller motor potential amplitudes or raised serum neurofilament light chain level.
ABSTRACT
Reactivation of the varicella zoster virus as herpes zoster (shingles) typically affects the peripheral nerves, resulting in a painful rash, most often on the torso. However, it can also manifest ophthalmologically, affecting the ophthalmic division of the trigeminal nerve. This manifestation is associated with a particularly high level of morbidity and may result in blindness. A new recombinant shingles herpes zoster vaccine protects patients against this virus and post-infection sequelae, improving medical and psychosocial outcomes. © 2021 Medicine Today Pty Ltd.

ABSTRACT
CASE: A 72 year old male presented to the outpatient clinic with a “vaccine reaction” after he developed a left arm rash following his Moderna COVID-19 booster. He had received the Moderna vaccines in March & April with the only side effect being arm soreness. On 10/30/2021, he received his booster in his lateral left upper arm. Three days later, he reported arm soreness that progressed in intensity by day 6 and developed a rash. Patient had no prior history of shingles and had received the SHINGRIX vaccine. Medical history was remarkable for subtotal colectomy with ileostomy 2/2 to Crohn's disease, stage III CKD, hypertension, HLD, amputations of the right big toe and left metatarsal 2/2 to osteomyelitis. Home medications included daily allopurinol 100mg, amlodipine 5mg, mesalamine 1,000 mg and octreotide 200 mcg/mL injection 0.5mL SQ BID. Presenting vital signs were normal. A physical exam revealed vesicles on an erythematous base in a C5 dermatome distribution. Incidentally, there was a concentration of vesicles located at the Moderna Booster vaccine site. Rash collected in groups of vesicles on the anterior forearm. Due to delay in presentation and stage III CKD, antivirals were not prescribed. Patient was prescribed Gabapentin 300mg nightly for pain and instructed to continue OTC Tylenol. After several weeks the rash resolved and pain subsided. IMPACT/DISCUSSION: Approximately 4% of patients with a history of Varicella develop a recurrent episode later in life with people who are immunosuppressed most affected. Possible triggers of zoster (HZ) include external reexposure to the virus, acute or chronic diseases such as malignancies or infections (i.e COVID-19), medications and stress. As of 12/5/21, the Vaccine Adverse Event Report System (VAERS) reported shingles in 1200 patients after receiving Pfizer vaccine, 1201 Moderna, and 1203 in Janssen vaccine recipients. While these reports are unable to be validated, it is important for clinicians to recognize the suggested relationship. Hypotheses of why our patient developed shingles include: 1) the immune activation from the vaccine activated dormant varicella, 2) the patient being older & immunocompromised puts him at a higher risk of developing HZ in general, and 3) the vaccine triggers a transient lymphopenia similar to being infected with COVID-19 and lymphopenia causes reactivation. As we continue to reach higher percentages of individuals receiving vaccines, we likely will continue to encounter cases such as described. CONCLUSION: It is important for clinicians to be aware of HZ reaction post COVID vaccination and to have this in their differential when a patient complains of a “reaction” to the vaccine. We regret that the patient being mis-triaged as an “allergic reaction” led to the patient being evaluated outside of the possible window of acute treatment of HZ. By describing this case we hope clinicians will be more aware of this relationship and prevent delay to treatment or misdiagnosis.
ABSTRACT
CASE: JW is a previously healthy 27-year-old woman who presented with several months of progressive weakness, neuropathy, and tachycardia that began shortly after her second dose of the Pfizer COVID-19 vaccine. Initially, she noticed fatigue followed by occipital neuralgia and paresthesia. Weeks later, she was febrile with extremity tremors and neuralgia. She went to the ED where she was lymphopenic, group A strep positive (GAS+), and had unremarkable imaging;she was given antibiotics and gabapentin. Her fever resolved, but her pain/tremor continued. Occipital nerve blocks provided temporary relief;acyclovir and duloxetine had no effect. On two subsequent ED visits, she was again GAS+ and was given additional antibiotics. Later, she developed non-pruritic rash, dermatographia, and blepharitis;skin biopsy showed non-vasculitic progressive pigmented purpura. An extensive rheumatologic, post-infectious, and paraneoplastic workup was unrevealing. Notably, she had high anti-COVID-19 spike antibody on qualitative assay. During workup, her symptoms rapidly worsened, leading to admission. On exam, she had intact sensation, profound gait imbalance, and HR to 150s with standing. LP was negative;EMG ruled out large fiber polyneuropathy (LFPN). She was diagnosed with autoimmune small fiber polyneuropathy (SFPN) and POTS. She improved rapidly with IVIG and steroids. Given her negative workup, the COVID-19 vaccine was identified as the likely trigger. IMPACT/DISCUSSION: Despite being common, SFPN is undiagnosed in many patients, likely due to its non-specific symptoms and low awareness among physicians. Furthermore, SFPN and LFPN often coexist, complicating the diagnosis of SFPN which typically requires confirmatory skin biopsy. Postvaccine SFPN has been described, including a milder case following the Pfizer COVID-19 vaccine. Symptoms typically progress chronically, follow a Guillain-Barré-like presentation, and may include dysautonomia. SFPN is thought to be mediated via humoral autoimmunity and autoreactive B-cells. Treatment is immunoglobulins and steroids. That JW's case progressed through the healthcare system for several months prior to diagnosis demonstrates two key points: 1) despite the ubiquity of SFPN, scant diagnostic tools and the subjective and chronic nature of symptoms may result in underdiagnosis;2) given the public discourse around vaccination and the rarity of adverse effects, there may be a tendency to dismiss complaints related to vaccines. Despite JW's early suggestion that the COVID19 vaccine caused her symptoms, post-vaccine syndromes were not considered until late in the course. CONCLUSION: SFPN should be considered in any patient with neuropathy. Clearer diagnostic criteria for SFPN are needed and may improve patient outcomes and enable more clinical trials. COVID-19 vaccination can trigger polyneuropathy. Vaccine-related adverse outcomes should remain on the differential when symptoms begin shortly after vaccination, despite the rarity of such outcomes.
ABSTRACT
Background: Due to COVID pandemic, there have been increased needs for ECMO circuits to support patients with respiratory failure1. Unfortunately, due to pharmacokinetics alteration of commonly used sedative and psychotropic medications by the ECMO circuits2,new sedation approaches to manage delirium and agitation is required. We present a case of COVID pneumonia patient on ECMO support, whose delirium symptoms were managed with a novel psychopharmacotherapy protocol. Case: Mr. M is a 57-year-old male patient with past medical history of obesity, hypertension, admitted to Stanford Hospital due to COVID pneumonia, complicated by respiratory failure, required to be on Veno-Venous ECMO support with bridge to transplant. He had significant hyperactive delirium with Richmond Agitation-Sedation Scale (RASS) score of +3 and ICDSC score of 7 for most of the days, despite heavy conventional pharmacological sedation. We observe the same problems with most patients placed on the ECMO system, leading to an investigation and development of a new protocol. Discussion: Patient on ECMO support requires adequate sedation to prevent clinical deterioration that can result from hyperactive delirium (ie., chugging, blood clots or decannulation)2. Nevertheless, ECMO circuit’s significant alterations of drug pharmacokinetics, such as increased volume of distribution and sequestration of lipophilic and protein bound medications, with no clear guidelines on managing sedation/delirium in patients with ECMO support at this time2, we conducted an extensive literature search and developed a novel protocol. This new sedation approach includes alpha-2 agonists, opioids, barbiturates and calcium channel modulators with the lowest lipophilicity and protein binding potential of each medication in its class4,5,thus overcoming the challenges introduced by ECMO circuits. The new protocol allowed the patient to participate in lung transplant work-up, physical therapy, and eventually facilitated receiving bilateral lung transplantation. Conclusion/Implications: ECMO is a life saving device that can help patient with cardiac-respiratory failure, and its use has been increasing in clinical practice. However, there needs to be an improvement in successful sedation/delirium management to minimize adverse events, and optimize the success of this lifesaving technologies. References: 1.

ABSTRACT
A 51-year-old woman presented acutely to dermatology with an 8-week history of painful, purple discolouration of her toes, which started on her left foot but progressed to involve all of her toes. She was noted to have a positive COVID-19 polymerase chain reaction test after her symptoms began. There was some superficial ulceration of two of her toes. The episode lasted for 5 weeks;however, after 6 weeks her toes had flared again. No triggers were indentified;in particular, her symptoms were not related to the cold. There were no other rashes. She has a past medical history of endometriosis and gout. She takes desogestrel and allopurinol, which she had been on for 2 years. Vasculitis screen was negative. She was treated initially with clobetasol propionate and nifedipine. On follow-up 6 weeks later, the patient reported hypersensitivity of her toes, with severe pain reported from socks rubbing against her toes. The toes had normal appearances and cool peripheries. We suspect that the increased sensitivity and pain is a reflex sympathetic response secondary to 'COVID toes' and have treated with it gabapentin. It is thought that reflex sympathetic dystrophy occurs because inflammation causes damage to the nerves;however, the exact mechanism behind reflex sympathetic dystrophy is yet to be elucidated.
ABSTRACT
Introduction: A 19-year-old non-verbal male with history of CHARGE syndrome, severe autism, intellectual disability, coloboma with blindness OD and severely imparied vision OS, deafness, self-injurious and aggressive behavior, Tetralogy of Fallot status post repair, pulmonary valve replacement, hypertension, hypothyroidism, megacolon, gastrostomy tube dependence, eosinophilic esophagitis and chronic kidney disease with an irregular sleep cycle who has failed multiple medications for insomnia has shown treatment success with suvorexant. Report of Cases: This patient's sleep schedule ranges from 1.5 to 5 hour segments at various times of day or night including naps at school with occasional longer periods of sleep up to 10 hours and longer periods of wakefulness up to 22 hours who has been treated with the following medications: trazodone, clonidine, hydroxyzine, diphenhydramine, quetiapine, gabapentin, mirtazapine, eszopiclone, melatonin and ramelteon. His behavioral problems have been treated with olanzapine. He continued to be aggressive and difficult to direct. His parents reported exhaustion. Then, suvorexant 5mg was added at bedtime while the following sleep medications were continued: gabapentin total daily dose of 1500mg (300mg in morning and 3pm;900mg at bedtime, 300mg one hour later if still awake), ramelteon 8mg, mirtazapine 7.5mg and olanzapine 10mg at bedtime and bid prn aggressive behavior. He also takes the following daily medications: bisacodyl, polyethylene glycol, simethicone, hyoscyamine, cholecalciferol, aspirin, levothyroxine, hypoallergenic nutritional formula, starch and albuterol prn. With the addition of suvorexant 5mg, he had been able to get 9.5 hours of consolidated sleep at night with improvement in his behavior until he contracted Covid-19 and regressed. The suvorexant dose was increased to 10mg which again improved his insomnia and behavior. Conclusion: Various medications have either not worked at all or have worked suboptimally for insomnia in this medically complex patient who has an irregular Circadian rhythm disorder. Adding an orexin receptor antagonist as a novel mechanism to his regimen has shown promise. At this time, this patient has been stable for one month with suvorexant 10mg at bedtime after regression on the 5mg dose that coincided with a Covid-19 infection. We are proceeding with cautious optimism.
ABSTRACT
Objective: To report a case series documenting biopsy-proven small fiber neuropathy (SFN) after COVID-19. Background: Patients recovering from COVID-19 who present with sensory as well as autonomic symptoms, including positional orthostatic tachycardia syndrome (POTS), frequently have negative electrodiagnostic testing. Skin biopsy may be required to reveal SFN. Design/Methods: This is a retrospective case series of patients seen in the Yale Neurology COVID-19 Clinic with positive SARS-CoV-2 PCR or antibody or a clinically consistent illness. After laboratory testing and a negative nerve conduction study, all patients underwent skin biopsy to test for intraepidermal SFN. Case 1: A 40F with pre-diabetes (HbA1c 6.2%) developed burning, numbness, and tingling in the hands and legs and POTS 6 weeks after acute COVID-19. Skin biopsy demonstrated non-length dependent SFN. Complete remission of neuropathy symptoms occurred within days of intravenous immunoglobulin (IVIG) therapy, which has been continued longitudinally. Case 2: A 65F with non-insulin dependent diabetes (HbA1c 8.0%) developed excruciating burning pain in her feet and orthostasis within weeks of acute COVID-19. Skin biopsy demonstrated non-length dependent SFN. She experienced partial relief of symptoms after IVIG and gabapentin. Case 3: A 43F with pre-diabetes (HbA1c 6.0%) developed orthostasis, numbness, paresthesias, and a “sunburned” feeling in her face, back, hands, and feet 2 weeks after acute COVID-19. Skin biopsy demonstrated length-dependent SFN. Symptoms improved over several months of pregabalin treatment, but have not resolved. The patient deferred immunotherapy. Case 4: A 40M developed POTS, numbness, and paresthesias in his face and left leg up to the knee within weeks of a clinical COVID-19 illness. Skin biopsy demonstrated non-length dependent SFN. IVIG therapy has resulted in significant improvement in symptoms. Conclusions: Sensory symptoms and POTS occur post-COVID, and SFN should be considered in the differential. Given the time of onset and response to immunotherapy, post-COVID SFN may have an underlying autoimmune etiology.
ABSTRACT
Methods: We reviewed reports of post COVID dysautonomia and management strategies pursued to understand best practices and provide a primer for clinicians to guide patient management. We reviewed the literature for case reports of post COVID dysautonomia and compiled the cases into a table. Treatment approaches and outcomes were aggregated into an algorithm for management guidance. Results: Ten studies regarding post COVID dysautonomia were reviewed. Strategies included conservative approaches such as fluids, salt consumption, compression stockings, abdominal binders and head of bed elevation as well as strength building such as yoga, resistance exercise, and recumbent physical activity. Moreover, psychosocial support including cognitive behavioral therapy, biofeedback, and support groups were emphasized along with pharmacologic remedies such as midodrine, ivabradine, fludrocortisone, intravenous immunoglobulin, gabapentin, and topical lidocaine in additoin to interventions such as enhanced external counterpulsation. Primary and secondary outcomes included self-report surveys, autonomic laboratory testing, hand grip strength and heart rate variability. Background: Growing numbers of cases of dysautonomia after acute COVID-19 infection are being reported involving previously healthy patients. This post-COVID dysautonomia is predominantly characterized by lingering neurologic and cardiovascular dysfunction including tachycardia, orthostatic intolerance, migraine, exercise intolerance, fatigue, and cognitive impairment. Anxiety, insomnia, and uncertainty surrounding the COVID-19 pandemic present additional risk factors for sympathetic overdrive and deconditioning. Best management strategies and practice guidelines for this patient population remains unknown. Conclusion: Our review suggests consideration of an integrative, multimodal treatment approach involving physical activity, mental well-being, nutrition, stress management, and medication. These primarily facilitate management of dysautonomia, but rarely lead to complete symptom resolution. Despite the uncertainty associated with post-COVID dysautonomia, patient validation, education, and lifestyle approaches provide the cornerstone of management. Since post-COVID dysautonomia will comprise an increasing number of care consultations, clinician awareness, prompt diagnosis, and personalized management are essential.
