Hypertrophic pachymeningitis (HP) is a rare presentation with duramater thickening and fibrosis which can result in cranial or spinal compressive disease. Most cases of spinal HP require surgical management. We present an uncommon case of idiopathic hypertrophic spinal pachymeningitis (IHSP) in a 40-year-old male who showed complete improvement to steroids without any further relapses. The patient presented with bilateral upper limb weakness with magnetic resonance imaging (MRI) spine showing diffuse dural thickening of the entire spine with cervical cord compression...

Coffee, black with a spritz of milk. I enjoyed routine, and today was no different. We were on the 12th floor of the "tower", as our hospital is lovingly called. It was my second year of residency, and I was charged with admissions to our neurological ward. Sighing with the expectation of a long day, I walked over to our patients. The first was a woman in her sixties. She complained of trouble swallowing for the past 2 months that was getting worse. She was otherwise healthy. Asked about her social background, she looked over to her husband with an impish grin and replied: "happily married for almost thirty years...

Cerebellar pial arteriovenous fistula (PAVF) in adults presenting with congestive edema of the brainstem and cervical cord has rarely been reported. Here, we report such a case. A 59-year-old man presented with progressive weakness and numbness of the limbs and hiccups for 6 months. On physical examination, his limbs had grade III muscle strength, and he was unable to stand or walk. He also had occasional incontinence and retention. There was a positive Babinski sign in both lower limbs. Below the neck, he had hypoesthesia of the skin...

Hereditary sensory and autonomic neuropathy type 4 (HSAN4), also known as congenital insensitivity to pain with anhidrosis (CIPA), is a rare genetic disorder caused by NTRK1 gene mutations, affecting nerve growth factor signaling. This study investigates the central nervous system's (CNS) involvement and its relation to pain insensitivity in HSAN4. We present a 15-year-old girl with HSAN4, displaying clinical signs suggestive of CNS impact, including spasticity and a positive Babinski's sign. Using Technetium-99m ethyl cysteinate dimer single-photon emission computed tomography (Tc-99m ECD SPECT) imaging, we discovered perfusion deficits in key brain regions, notably the cerebellum, thalamus, and postcentral gyrus...

BACKGROUND Involvement of the central nervous system during infection with dengue virus (DENV) is recognized. However, ischemic stroke is rarely reported. Herein are described 2 cases of patients with ischemic stroke in which DENV infection was demonstrated. CASE REPORT The first patient was a 51-year-old woman that presented altered consciousness, monoparesis, facial palsy, dysarthria, Babinski sign, and syncope 7 days from the onset of fever. She had a history of carotid artery atherothrombosis and previous stroke...

Introduction: We investigated the biomechanical behaviour of different fixations of the tibial posterior malleolus (TPM), simulating distinct situations of involvement of the tibiotalar articular surface (TTAS) through a finite element model (FEM). Material and methods: A 3D computer-aided design model of the left ankle was obtained. The materials used were divided according to their characteristics into ductile and non-ductile, and all materials were assumed to be linear elastic, isotropic, and homogenous...

Domestication of cranberry and blueberry began in the United States in the early 1800s and 1900s, respectively, and in part owing to their flavors and health-promoting benefits are now cultivated and consumed worldwide. The industry continues to face a wide variety of production challenges (e.g. disease pressures), as well as a demand for higher-yielding cultivars with improved fruit quality characteristics. Unfortunately, molecular tools to help guide breeding efforts for these species have been relatively limited compared with those for other high-value crops...

Since hypothalamic obesity (HyOb) was first described over 120 years ago by Joseph Babinski and Alfred Fröhlich, advances in molecular genetic laboratory techniques have allowed us to elucidate various components of the intricate neurocircuitry governing appetite and weight regulation connecting the hypothalamus, pituitary gland, brainstem, adipose tissue, pancreas and gastrointestinal tract. On a background of an increasing prevalence of population-level common obesity, the number of survivors of congenital (e...

A woman in her 20s presented with ascending weakness and paraesthesia along with flu-like symptoms. Neurological examination revealed right facial numbness along V2 distribution and flaccidity in her lower extremities, with a motor power of 0/5 throughout. The T4 sensory level and bilaterally positive Babinski sign were noted. Brain MRI revealed multiple bilateral T2/fluid attenuated inversion recovery hyperintense lesions with central enhancement involving the right trigeminal nerve. Full spine MRI demonstrated long-segment thoracic cord demyelination extending from T1 to T11 and nerve root enhancement...

Very little is known about the mechanisms underlying the development of personality disorders, hindering efforts to address early risk for these costly and stigmatized disorders. In this study, we examined associations between social and monetary reward processing, measured at the neurophysiological level, and personality pathology, operationalized through the Level of Personality Functioning (LPF), in a sample of early adolescent females (Mage  = 12.21 years old, SD = 1.21)...

BACKGROUND: Neurological opportunistic infections cause significant morbidity and mortality in people with human immunodeficiency virus (HIV) but are difficult to diagnose. METHODS: One hundred forty people with HIV with acute neurological symptoms from Iquitos, Peru, were evaluated for cerebral toxoplasmosis with quantitative polymerase chain reaction (qPCR) of cerebrospinal fluid (CSF) and for cryptococcal meningitis with cryptococcal antigen test (CrAg) in serum or CSF...

Modulation-doped CdTe quantum wells (QWs) with Cd0.7 Mg0.3 Te barriers were studied by photoluminescence (PL) and far-infrared Fourier spectroscopy under a magnetic field at 4.2 K and by Raman spectroscopy at room temperature. Two samples were tested: a sample which contained ten QWs (MQW) and a sample with one QW (SQW). The width of each QW was equal to 20 nm, and each of them was modulation-doped with iodine donors introduced in a 4 nm thick layer. The concentration of donors in each doped layer was nominally identical, but the thickness of the spacer in SQW and MQW samples was 20 and 10 nm, respectively...

A 72-year-old man sought care for a cognitive deterioration over the past 5 years. There was a documented decline in his performance on the Mini-Mental State Examination (30 of 30 in 2016, 23 of 30 in 2021), with mainly episodic memory impairment. A more detailed history revealed a gait problem, paresthesia in both feet, and nocturnal urinary frequency. Clinical examination findings were suggestive of a length-dependent polyneuropathy. In addition, a right-sided Babinski sign was noted. Electromyography and a nerve conduction study corroborated a peripheral axonal sensorimotor neuropathy...

STUDY DESIGN: Delayed diagnosis of degenerative cervical myelopathy (DCM) is likely due to a combination of its subtle symptoms, incomplete neurological assessments by clinicians and a lack of public and professional awareness. Diagnostic criteria for DCM will likely facilitate earlier referral for definitive management. OBJECTIVES: This systematic review aims to determine (i) the diagnostic accuracy of various clinical signs and (ii) the association between clinical signs and disease severity in DCM? METHODS: A search was performed to identify studies on adult patients that evaluated the diagnostic accuracy of a clinical sign used for diagnosing DCM...

OBJECTIVE: To compare the collagen, elastic fibers, and smooth muscle content of the clitoris and the glans penis in young adults. MATERIALS AND METHODS: The clitoris and the glans penis of six women and six men (mean age 25±3) who died as a result of accidents were excised. The samples were placed under a formaldehyde solution and histologically processed. Masson's trichrome and Weigert's resorcin-fuchsin stain was used to highlight the elastic fibers, smooth muscle, and collagen...

This study investigates the chronology of copper (Cu) contamination and its stable isotopes within an emblematic Brazilian mangrove impacted by multiple urban and industrial Cu sources, deforestation, and eutrophication. In particular, it tests Cu isotopes as tracers of anthropogenic inputs into an anthropized watershed impacted by multiple sources. To do so, we used multi-isotopic approaches (δ65 Cu, δ13 C, and δ15 N), elemental analyses (Al, Ca, Fe, P, Cu, C, and N), and selective and sequential extractions in a210 Pb-dated sediment core...

To fully explore exciton-based applications and improve their performance, it is essential to understand the exciton behavior in anisotropic materials. Here, we investigate the optical properties of anisotropic excitons in GeS encapsulated by h-BN using different approaches that combine polarization- and temperature-dependent photoluminescence (PL) measurements, ab initio calculations, and effective mass approximation (EMA). Using the Bethe-Salpeter Equation (BSE) method, we found that the optical absorption spectra in GeS are significantly affected by the Coulomb interaction included in the BSE method, which shows the importance of excitonic effects besides it exhibits a significant dependence on the direction of polarization, revealing the anisotropic nature of bulk GeS...

BACKGROUND: Spinal meningioma is a common intraspinal tumor, which mainly occurs in the thoracic spine. Ossified meningioma (OSM) is an extremely rare histological variant. Our article reports a rare patient with dorsal complete OSM and reviews this subject. CASE PRESENTATION: A 68-year-old woman presented with a one-year history of progressive weakness in both lower limbs with gait disturbance. Physical examination revealed hypoesthesia with a sensory level below T10...

Anton-Babinski syndrome (ABS) is a rare neuropsychiatric condition characterized by visual anosognosia (denial of vision loss) and confabulation in the presence of intact anterior visual tracts. The most common cause of ABS is a cerebrovascular accident involving bilateral occipital lobe injuries with varying degrees of cortical blindness. In this report, we present the case of a woman with suspected ABS following a recurrent ischemic stroke in Malaysia. Establishing a proper diagnosis of stroke is crucial for modifying rehabilitation goals to ensure improved functional outcomes...

BACKGROUND: Primary intramedullary spinal cord lymphoma (PISCL) is rare and easily misdiagnosed with the lack of typical clinical features and non-specific imaging manifestations. CASE PRESENTATION: A 49-year-old man was admitted to our hospital because of persistent limbs numbness, pinprick-like pain in the posterior neck and unsteady gaits. He has brisk tendon reflexes and positive Babinski's sign. Magnetic resonance imaging (MRI) of the cervical spine showed an abnormal signal with aberrant reinforcement at medulla oblongata and the level of C1-C7...
