Listeria brainstem encephalitis with myelitis is extremely rare in clinical practice.Since the clinical manifestations are non-specific,MRI is helpful for diagnosis.Positive cerebrospinal fluid culture is considered the gold standard for diagnosis.This article reports a case of an immunocompetent individual with listeria brainstem encephalitis with myelitis,aiming to enhance the awareness of this condition.

INTRODUCTION

Demyelinating central nervous system (CNS) disorders such as transverse myelitis (TM) and multiple sclerosis (MS) have been reported with mRNA Covid-19 vaccine. Some cases were relapses of a pre-existing condition but de novo and initial presentation of MS after BNT162b2 COVID-19 mRNA vaccine has very rarely been documented.

We report a 72-year-old female, right-handed, Filipina, with a one-month history of bilateral lower extremity weakness which occurred 7 days after she received her first booster dose of BNT162b2 mRNA vaccine. This was later accompanied by fecal and urinary incontinence. On examination, she had motor deficit below L1 myotome manifesting with loss of hip flexion, knee extension, dorsiflexion, and plantar flexion. There was also sensory deficit below T10 level with relative 80% sensation of vibratio, proprioception, light touch and complete loss of pain and temperature sensation. The initial impression was Transverse Myelitis which may be related to a post-vaccination state. Spinal magnetic resonance imaging (MRI) revealed long segment enhancing T2W hyperintense lesion at T2 to T7. Cranial MRI revealed ovoid areas of heterogeneous, predominantly T2/FLAIR hyperintense signals exhibiting restricted diffusion in the periventricular white matter of the fronto-parietal lobes. Cerebrospinal fluid (CSF) analysis was negative for infectious causes such as tuberculosis but with high levels of CSF immunoglobulin G. She was then diagnosed to have Multiple Sclerosis (MS) and was treated with high dose oral prednisone. However, there was no improvement in neurological deficits on follow-up.

This case adds to the reported rare cases of initial presentation of MS occurring after vaccination for COVID-19 and the first reported case in the Philippines. Early recognition and prompt treatment is important to improve outcomes.

The eradication of poliomyelitis is a landmark achievement in the history of public health, providing strong protection for children's health. The introduction of the Chinese Regulations for the Manufacture and Control of Live Poliovirus Vaccine is a prerequisite and safeguard for the large-scale production and use of domestically produced live poliovirus vaccines, serving as an indispensable component of vaccine safety. This article, based on archival documents, letters, collections of essays, and oral interviews, examines the historical experience of the development of Chinese Regulations for the Manufacture and Control of Live Poliovirus Vaccine. It contends that the emphasis on localization and the active engagement in international cooperation are critical factors in the swift introduction of Chinese Regulations for the Manufacture and Control of Live Poliovirus Vaccine.

Poliomyelitis, or polio, is a highly infectious disease and can result in permanent flaccid paralysis of the limbs. Singapore was certified polio-free by the World Health Organization (WHO) on 29 October 2000, together with 36 other countries in the Western Pacific Region. The last imported case of polio in Singapore was in 2006. Fortunately, polio is vaccine-preventable-the world saw the global eradication of wild poliovirus types 2 and 3 achieved in 2015 and 2019, respectively. However, in late 2022, a resurgence of paralytic polio cases from vaccine-derived poliovirus (VDPV) was detected in countries like Israel and the US (specifically, New York); VDPV was also detected during routine sewage water surveillance with no paralysis cases in London, UK. Without global eradication, there is a risk of re-infection from importation and spread of wild poliovirus or VDPV, or new emergence and circulation of VDPV. During the COVID-19 pandemic, worldwide routine childhood vaccination coverage fell by 5% to 81% in 2020-2021. Fortunately, Singapore has maintained a constantly high vaccination coverage of 96% among 1-year-old children as recorded in 2021. All countries must ensure high poliovirus vaccination coverage in their population to eradicate poliovirus globally, and appropriate interventions must be taken to rectify this if the coverage falters. In 2020, WHO approved the emergency use listing of a novel oral polio vaccine type 2 for countries experiencing circulating VDPV type 2 outbreaks. Environmental and wastewater surveillance should be implemented to allow early detection of "silent" poliovirus transmission in the population, instead of relying on clinical surveillance of acute flaccid paralysis based on case definition alone.

Xiaoxuming Decoction is an ancient classic herbal formula for the treatment of stroke. In ancient times, the connotation of stroke was very extensive, including facial neuritis, acute cerebral infarction, acute cerebral hemorrhage, sequelae of cerebral hemorrhage, unexplained weakness of limbs, cervical spondylosis, acute myelitis, acute radiculitis, Guillain Barre syndrome, multiple sclerosis, myasthenia gravis, motor neuron disease, dermatomyositis, hypokalemic paralysis peripheral neuritis. It has been identified that: ①Xiaoxuming Decoction is very common in the treatment of cerebrovascular diseases, such as cerebral infarction, cerebral hemorrhage and other cerebrovascular diseases, facial neuritis, acute myelitis, acute radiculitis, Guillain Barre syndrome, unexplained limb weakness, multiple sclerosis, motor neuron disease, myasthenia gravis, and rheumatic and immune system diseases, such as dermatomyositis, and can not only alleviate symptoms, but also improve prognosis and the long-term survival rate. ②Sudden limb failure, facial paralysis, and hypoalgesia without heat syndrome are the key indications of Xiaoxuming Decoction. ③This is a special prescription for the treatment of acute facial neuritis, and can cure in one week in the combination with moxibustion. ④In the treatment of facial neuritis complicated with hypertension or acute cerebrovascular disease, Xiaoxuming Decoction generally has a certain antihypertensive effect, without any hypertensive effect, which reflected its two-way regulatory effect for blood pressure. ⑤In the treatment of unknown limb weakness, acute myelitis, acute radiculitis, Guillain Barre syndrome, Xiaoxuming Decoction can rapidly alleviate the symptoms. ⑥This is the basic formula for multiple sclerosis and motor neuron disease. Long term use of Xiaoxuming Decoction can alleviate the symptom of limb weakness, reduce the occurrence of complications and delay the progress of the disease, but with a poor long-term prognosis. ⑦In the treatment of myasthenia gravis, Xiaoxuming Decoction can significantly improve muscle strength, and gradually help stop hormone reduction. After thymoma surgery, Xiaoxuming Decoction is also applicable to some patients with recurrent myasthenia gravis. ⑧Xiaoxuming Decoction also plays a role in the treatment of dermatomyositis and cervical spondylopathy. ⑨Raw ephedra is the monarch drug of Xiaoxuming Decoction, which is the key to the effect. The dosage starts with 6 g is titrated in a small dose and increases gradually. In addition, this formula is forbidden for those with red face, fast heart rate, high blood pressure, blocked stool, red tongue, yellow fur, wiry and rapid pulse or powerful pulse, and spout pulse.

Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory demyelinating autoimmune disease of central nervous system characterized by relapsing attacks that target the optic nerves and spinal cord, as well as aquaporin-4 (AQP4) enriched periventricular brain regions. The area postrema (AP), located in the dorsal medulla, is the chemosensitive vomiting center and has high AQP-4 expression. The AP syndrome with unexplained hiccups, nausea, and vomiting is one of the core clinical characteristics in the NMOSD and maybe the first presenting symptom. We experienced a 25-year-old woman presented with intractable vomiting, dizziness and oscillopsia. Upbeat nystagmus detected on the bedside examination led to comprehensive neurological workups including magnetic resonance imaging, and she was diagnosed as the AP syndrome. Ten months later, she experienced a recurrence as a longitudinally extensive transverse myelitis and the diagnosis was finally compatible with NMOSD without AQP4-IgG. NMOSD, especially the AP syndrome, should be considered in any dizzy patient with intractable vomiting, and detailed neuro-otologic and neuro-ophthalmologic examinations are warranted for the correct diagnosis.
