Syphilis is an increasingly diagnosed venereal disease which has four distinctive stages that may last over decades if appropriate treatment is not given. Review of the files of the Pathology Museum in the Faculty of Medicine at The University of Adelaide revealed three cases with classical cardiovascular and neurological findings. Case 1: An 80-year-old man with a large syphilitic aneurysm of the ascending aorta with a smaller aneurysm of the proximal descending aorta. Case 2: A 56-year-old man with chronic syphilitic meningoencephalitis with cerebral atrophy. Case 3: A 77-year-old man with tabes dorsalis. Given the increase in cases coming to medical attention in recent years due to high-risk sexual activity, migration, travel and reduced access to medical treatment, an awareness of the classical features of syphilis is appropriate as some cases will undoubtedly require medicolegal evaluation.

Background: Tabes dorsalis is a late manifestation of untreated syphilis that is characterized by ataxia, lancinating pains, and urinary incontinence. A form of tertiary syphilis or neurosyphilis, it is the result of slow, progressive degeneration of the nerve cells in the spinal cord., Method: Case report., Findings: A 39-year-old man presented with tingling paresthesia in the lower limbs, difficulty in walking, and loss of vision. Magnetic resonance imaging (MRI) of the dorsal spine showed intramedullary hyperintensity and cord atrophy, similar to changes seen in subacute combined degeneration. MRI features of tabes dorsalis have not been described previously to the best of our knowledge., Conclusion: MRI findings in this patient with tabes dorsalis were similar to those seen in subacute combined degeneration, which is characterized predominantly by cord atrophy and intramedullary hyperintensities.

Study Design: The study has been designed as a case report., Objective: The objective of this study was to report a rare case of syringomyelia in a patient with syphilitic spinal meningitis., Setting: The Neurology Department, University Hospital Mohamed VI Marrakesh, Morocco., Case Report: A 40-year-old Moroccan male presented with the complaints of weakness of the lower extremities. Neurological examinations confirmed the motor dysfunction of the lower extremities and revealed a sensory loss to the T2-T4 dermatome. The magnetic resonance imaging (MRI) scan detected a hypointense signals on the T1 sequences and hyperintense signals on T2 in the cord extending from C7 to T4. The condition was diagnosed as dorsal syringmyelia. Blood and cerebrospinal fluid were positive for Venereal Disease Research Laboratory and Treponema pallidum hemagglutination tests. The patient was treated with intravenous penicillin therapy with a significant improvement in motor deficit. After 2 years, his neurological deficit was limited to a mild weakness of the distal right leg., Conclusion: A case of syphilitic spinal meningitis presenting with syringomyelia, and effectively treated with penicillin has been described.

Introduction: Neurosyphilis is rare today. It arises on average 20 years after poorly treated or untreated primary syphilis. Considering the decline in the incidence of syphilitic meningo encephalitis and the little known MRI aspects, we report the case of a patient affected by neurosyphilis occurring after primary syphilis untreated for 25 years., Case Report: A 65-year-old man presented typical clinical features including general paresis with psychiatric disorders, maniac access, and frontal syndrome as well as tabes dorsalis and Argyll-Robertson pupil. Brain MRI showed bilateral high intensity signals on the T2 weighted sequence located in mesiotemporal, insular, frontal regions., Conclusions: Very few cases of neurosyphilis with detailed brain MRI aspects have been reported. The interest of this case report is first to recall the importance of syphilitic serology in patients with subacute psychiatric disorders and secondly to present rarely reported aspects of the brain MRI., (Copyright © 2011.

The authors report three cases revealed by tabes arthropathy in patients younger than 45 years. The age of patients was respectively 42, 40, 42. The clinical symptoms consisted of a painless knee strain, isolated in one case, associated with radiculocordonal posterior syndrome in two cases. The radiological lesions showed bone destruction. The biological assessment was for a venereal disease. The outcome was disappointing, despite a well conducted treatment. The observation of such cases should suggest a syphilitic origin ahead any advanced painless arthropathy even in young patients.

Although infectious myelopathies are rare, timely and accurate diagnosis is essential to improving outcome. There are a number of organisms that may cause infectious myelopathies, including human immunodeficiency virus (HIV), human T-cell lymphotropic virus type I (HTLV-I), herpesviruses, enteroviruses, Treponema pallidum, Mycobacterium tuberculosis, fungi, and parasites. Vacuolar myelopathy, the most common form of spinal cord disease in HIV-infected individuals, is underrecognized clinically. The failure to diagnose this condition is generally a consequence of the attribution of the lower extremity weakness and paresthesias to general debility and concomitant peripheral neuropathy. Tropical spastic paraparesis or HTLV-I-associated myelopathy involves the pyramidal tracts, chiefly at the thoracic level, and results in spastic lower extremity weakness and a spastic bladder. The herpesviruses (varicella-zoster, herpes simplex type 2, cytomegalovirus) and the enteroviruses cause myelitis. Prior to the development of antibiotics, syphilis was the most frequent infectious cause of spinal cord disease. In light of the broad spectrum of pathogens that may affect the spinal cord and the variegate fashion in which these disorders may present, the physician must always consider an infectious etiology in the differential diagnosis for the patient presenting with myelopathy. This review addresses the infectious myelopathies by microorganism.

The circling rat is an autosomal recessive mutant (homozygous ci2/ci2) that displays lateralized circling behaviour, locomotor hyperactivity, ataxia and stereotypic head-movement. These abnormal behaviours occur in phases or bursts either spontaneously or in response to stress. Heterozygous (ci2/+) littermates display normal spontaneous behaviours. We have previously found that ci2/ci2 rats of both genders have a lower tissue content of dopamine in the striatum ipsilateral to the preferred direction of rotation, indicating that the rats turn away from the brain hemisphere with higher striatal dopaminergic activity. In view of the similarities of the motor syndrome of the ci2/ci2 mutant rat to that of mouse deafness mutants, the present study evaluated the hearing ability of the circling rat mutant by recording brainstem auditory-evoked potentials. To test for vestibular dysfunction, a swimming test was conducted. Histological methods were used to examine the cochlear and vestibular parts of the inner ear and the cochlear and vestibular brainstem nuclei for defects. The absence of auditory-evoked potentials demonstrated a complete hearing loss in the adult ci2/ci2 mutant rat, whereas heterozygous littermates exhibited auditory-evoked potentials with thresholds resembling those of other laboratory strains. Furthermore, the mutant rats were unable to swim. Histological analysis of the inner ear of adult mutants revealed virtually complete loss of the cochlear neuroepithelium, while no such hair cell degeneration was seen in the vestibular parts of the inner ear. However, part of the vestibular hair cells showed protrusions into the endolymphatic space, suggesting alterations in the cytoskeletal architecture. The histological findings in mutant circling rats strongly indicate that the hearing loss of the mutants is of the sensory neural type, the most prevalent type of hearing loss. In the cochlear nuclei of the brain stem of mutant rats, neurons exhibited an abnormal shape, reduced size and increased density compared to controls. In contrast, no abnormal neuronal morphology was seen in the vestibular nuclei, but a significantly reduced neuronal density was found in the medial vestibular nucleus. Abnormal vestibular function would be a likely explanation for the disturbed balance of mutant rats as exemplified by the ataxia and the inability to swim, whereas the previous data on these rats strongly indicate an involvement of the basal ganglia in the abnormal circling behaviour. The genetic defect in the mutant rats, thus, results in a clinical syndrome with features also seen in human genetic disorders with deafness and hyperkinesia, making the ci2/ci2 rat an excellent model for investigating both cochlear/vestibular dysfunction and hyperkinetic movement disorders.

Tabes dorsalis is uncommon and progresses slowly from infection to clinical manifestation. We report a rare case of rapidly progressive tabes dorsalis associated with selective IgA deficiency (sIgAD). A 28-year-old man was hospitalized with lightning back pain, nausea, and bladder bowel dysfunction. Serum and cerebrospinal fluid (CSF) revealed high titers of Treponema pallidum antibody, and the serum IgA level was less than 5 mg/dl. Thl-dominant cytokine expression was observed, as is usually seen in neurosyphilis. He was treated with Ceftriaxone and CSF pleocytosis disappeared. We postulate sIgAD influenced the atypical rapid clinical course of tabes dorsalis in this patient.

An association between syringomyelia and spinal syphilis was described in the early literature but has not been the subject of reports subsequently. We give details of a contemporary case, affirmed by magnetic resonance imaging. The patient showed significant clinical recovery following penicillin treatment, while the imaging appearances became less pronounced.
