Untreated syphilis can lead to ocular syphilis, otosyphilis, and neurosyphilis, conditions resulting from Treponema pallidum infection of the eye, inner ear, or central nervous system. During March-July 2022, Michigan public health officials identified a cluster of ocular syphilis cases. The public health response included case investigation, partner notification, dissemination of health alerts, patient referral to a public health clinic for diagnosis and treatment, hospital care coordination, and specimen collection for T...

BACKGROUND: We describe a case of EBV aseptic meningitis in a patient with HIV with an extensive history of prior infections and exposures. Detailed Case Description: A 35-year-old man with a history of HIV, syphilis, and partially treated tuberculosis presented with headache, fever, and myalgias. He reported recent exposure to dust from a construction site and had sexual contact with a partner with active genital lesions. An initial workup revealed mildly elevated inflammatory markers, significant pulmonary scarring from tuberculosis with a classic "weeping willow sign", and lumbar puncture findings consistent with aseptic meningitis...

INTRODUCTION: At the beginning of the coronavirus virus (COVID-19) pandemic, the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) was thought to cause mainly respiratory symptoms, largely sparing the brain and the rest of the nervous system. However, as the knowledge about COVID-19 infection progresses and the number of COVID19-related neurological manifestations reports increases, neurotropism and neuroinvasion were finally recognized as major features of the SARS-CoV-2. Neurological manifestations involving the central nervous system are sparse, ranging from headaches, drowsiness, and neurovascular attacks to seizures and encephalitis [1]...

Even after two years of the Coronavirus Disease 2019 (COVID-19) pandemic, despite known risk factors, we are still unable to predict the severity of the infection in specific patients. Due to the contradictory data, the protective role of immunosuppression in preventing the severe course of the infection remains uncertain. Therefore, we want to discuss the influence of several immunosuppressive factors on the COVID-19 pattern in children, based on two case reports regarding 17-year-old boys with other immunosuppressive factors and a completely different course of the disease...

The incidence of syphilis has increasing recently, largely attributable to improved screening that may result in the diagnosis of chronic untreated infections. These patients can develop severe or subtle neurologic symptoms that can be missed and, therefore, detected accidentally while a patient is evaluated for other mimicking neurological infections. A 58-year-old man with diabetes presented with 2 days of aphasia, headache, chills and confusion. He had an MRI brain with evidence of a prior cerebrovascular accident...

A 64-year-old male with a history of transverse myelitis presented to the hospital with a decreased level of consciousness of one day's duration. CT of the head revealed intracranial hemorrhage measuring 2 x 1.2 cm in the right temporal lobe and multiple small hemorrhages in the left hemisphere, suggestive of vasculitis. Initial vasculitis workup was negative for antinuclear antibody (ANA), complement component 3 (C3), and antineutrophil cytoplasmic antibodies: P-ANCA, C-ANCA. Syphilis, hepatitis B and C, West Nile virus antibody [immunoglobulin G (IgG) and immunoglobulin M (IgM)], herpes simplex virus (HSV) polymerase chain reaction (PCR), and HIV 1 and 2 were also negative...

A healthy 47-year-old immunocompetent man from Northern Canada presented for ophthalmologic assessment after experiencing one month of right-sided photopsias, floaters, and a right lower nasal quadrant visual field defect. Optic disc swelling, vitritis, chorioretinitis, peripheral retinal infiltrates and hemorrhages were noted in the right eye. A broad right inferior arcuate and nasal visual field defect were also present. Fluorescein angiography of the right retina showed dilated disc vessels and staining of the optic disc...

Frequency of Treponema pallidum invasion into cerebrospinal fluid (CSF) has not been clear at this present. Since it is impossible to culture T. pallidum in vitro at this present, we need molecular based-approach to detect it in CSF. Additionally, neurosyphilis is usually a late sequela, however it might result in asymptomatic neurosyphilis even at primary or secondary syphilis. This study was to reveal the frequency of T. pallidum invasion into CSF especially at primary or secondary syphilis with polymerase chain reaction (PCR) test...

From the discovery of the Zika virus (ZIKV) in 1947 in Uganda (Africa), until its arrival in South America, it was not known that it would affect human reproductive life so severely. Today, damage to the central nervous system is known to be multiple, and microcephaly is considered the tip of the iceberg. Microcephaly actually represents the epilogue of this infection's devastating process on the central nervous system of embryos and fetuses. As a result of central nervous system aggression by the ZIKV, this infection brings the possibility of arthrogryposis, dysphagia, deafness and visual impairment...

BACKGROUND: Laboratory diagnosis of neurosyphilis is complicated especially when it is asymptomatic, no single laboratory test result being appropriate to diagnose central nervous system infectivity caused by Treponema pallidum. Our objective was to evaluate two polymerase chain reaction (PCR) techniques for the detection of T. pallidum DNA in the cerebrospinal fluid (CSF) of patients with syphilis. METHODS: One hundred twenty-four CSF samples from patients with reactive blood tests for syphilis were obtained...

Varicella zoster virus may cause vasculitis or vasculopathy, and positive polymerase chain reactions for varicella zoster virus deoxyribonucleic acid in the cerebrospinal fluid and/or the intrathecal synthesis of antibodies to the varicella zoster virus suggest these diagnoses. Meningovascular syphilis may involve the middle cerebral artery and basilar artery and may cause a stroke. Aspergillus is vasoinvasive and may cause hemorrhagic infarction by forming an intravascular thrombus.

Neurosyphilis refers to infection of the central nervous system by Treponema pallidum, which may occur at any stage. Neurosyphilis has been categorized in many ways including early and late, asymptomatic versus symptomatic and infectious versus non-infectious. Late neurosyphilis primarily affects the central nervous system parenchyma, and occurs beyond early latent syphilis, years to decades after the initial infection. Associated clinical syndromes include general paresis, tabes dorsalis, vision loss, hearing loss and psychiatric manifestations...

A 35-years-old right-handed man admitted to our hospital with a worsening of dysarthria, left facial palsy and left hemiparesis for 2 days. Acquired immunodeficiency syndrome (AIDS) was diagnosed when he was 28 years old. At that time, he also was treated for syphilis. After highly active antiretroviral treatment (HAART) was introduced at the age of 35 years old, serum level of human immunodeficiency virus (HIV) was not detected, but the number of CD4+ T cells was still less than 200/μl. He had no risk factors of atherosclerosis including hypertension, diabetes and hyperlipidemia...

It is established that chronic spirochetal infection can cause slowly progressive dementia, brain atrophy and amyloid deposition in late neurosyphilis. Recently it has been suggested that various types of spirochetes, in an analogous way to Treponema pallidum, could cause dementia and may be involved in the pathogenesis of Alzheimer's disease (AD). Here, we review all data available in the literature on the detection of spirochetes in AD and critically analyze the association and causal relationship between spirochetes and AD following established criteria of Koch and Hill...

Syphilis is a frequent coinfection with human immunodeficiency virus (HIV). Whereas systemic syphilis infection increases plasma HIV RNA levels (viral load; VL), effects of syphilis on cerebrospinal fluid (CSF) VL are unknown. We hypothesized that intrathecal immune activation in neurosyphilis would selectively increase CSF VL in coinfected patients. In this study, HIV-infected research subjects (N = 225) were categorized into three groups based on serum rapid plasma reagin (RPR), microhemaglutination for Treponema pallidum (MHA-TP) MHA-TP, and CSF VDRL: 23 with neurosyphilis (NS+; reactive serum RPR and MHA-TP and positive CSF VDRL); 42 with systemic syphilis but not neurosyphilis (Syph+; reactive serum RPR and MHA-TP; negative CSF VDRL), and 160 without syphilis (Syph-; nonreactive serum RPR)...

BACKGROUND: Moyamoya disease is an occlusion of the terminal portion of internal carotid arteries and proximal portion of middle and anterior cerebral arteries of unknown origin. Moyamoya syndrome is associated with meningitis, tuberculosis, syphilis, head trauma, head irradiation, brain tumor, von Recklinghausen's disease, tuberous sclerosis, Marfan syndrome, sickle cell anemia, arteriosclerosis, hypertension, and oral contraceptive use. To our knowledge, acquired immunodeficiency syndrome (AIDS) as a cause of moyamoya syndrome has not been reported in an adult population...

The questions most often asked of my residents and myself are the following: (1) How do you interpret the cerebrospinal fluid white blood cell count and polymerase chain reaction results when the lumbar puncture has been traumatic? (2) Does the older adult with a serum sample that tests positive by the Venereal Disease Research Laboratory test need spinal fluid analysis for neurosyphilis, and which of those syphilis tests can become nonreactive even though the patient is never treated? (3) Do you give steroids to patients with bacterial meningitis? (4) What do you do for the patient with cryptococcal meningitis who develops a spastic gait? (5) Are all cases of transverse myelitis "idiopathic"? and (6) When does the patient who has had a stroke need spinal fluid analysis to rule out an infectious etiology? This is how we answer these questions...

BACKGROUND: Identification of infants with Treponema pallidum infection of the central nervous system remains challenging. METHODS: We used rabbit-infectivity testing of the cerebrospinal fluid to detect T. pallidum infection of the central nervous system in infants born to mothers with syphilis. The results were compared with those of clinical, radiographic, and conventional laboratory evaluations; IgM immunoblotting of serum and cerebrospinal fluid; polymerase-chain-reaction (PCR) assay testing of serum or blood and cerebrospinal fluid; and rabbit-infectivity testing of serum or blood...

OBJECTIVES: To establish a model of CNS invasion by Treponema pallidum and to use it to investigate the immune mechanisms responsible for clearance. METHODS: Four macaques were intrathecally inoculated with 0.6 to 2.1 x 10(8) T. pallidum and underwent clinical examinations and blood and CSF collections every 1 to 2 weeks for 12 to 13 weeks. The following were determined: serum Venereal Disease Research Laboratory (VDRL) and microhemagglutination-T. pallidum reactivities, CSF-VDRL, CSF white blood cell (WBC) count, and the presence of viable T...

IgM immunoblotting and polymerase chain reaction (PCR) were evaluated for use in diagnosing congenital syphilis, and the prevalence of central nervous system (CNS) invasion by Treponema pallidum during congenital infection was examined. The results of rabbit infectivity testing (RIT) on serum and cerebrospinal fluid (CSF) of 19 infants born to mothers with untreated early syphilis were compared with results of PCR and IgM immunoblotting. Seven infants had clinical evidence of congenital syphilis supported by positive serum IgM immunoblot (7/7), PCR (6/7), and RIT (3/3)...
