Neurologic Complications of Leprosy: A Case Series.

Leprosy, caused by the Mycobacterium leprae complex, manifests as a chronic infection. Its hallmark presentation involves the neurocutaneous syndrome, characterized by peripheral nerve involvement and dermatologic lesions. Neurological complications significantly contribute to disability in leprosy patients. Peripheral neuropathy may manifest acutely or chronically, in either axonal or demyelinating forms, and can present as mononeuropathy, mononeuropathy multiplex, or polyneuropathy. The diverse clinical presentations emphasize the importance of considering leprosy in the differential diagnosis of peripheral neuropathy, enabling appropriate investigative approaches. Skin and nerve biopsies, slit skin smears, and nerve conduction studies serve as crucial diagnostic tools for identifying peripheral nerve involvement in leprosy. In this paper, we present three cases of leprosy with peripheral nerve involvement, discussing their clinical spectrum, diagnostic approach, and management.

Tumefactive Demyelinating Lesions: An Illustrative Pediatric Case With an Atypical Presentation and Literature Review.

Tumefactive demyelinating lesions remain a rare entity and a source of diagnostic difficulty. Here, we report the case of a teenage girl who presented with a one-month history of progressive quadriparesis and symptoms of intracranial hypertension. Brain MRI showed multiple large subcortical white matter lesions with both open- and closed-rim enhancement on gadolinium injection. The patient subsequently underwent a brain biopsy which showed an inflammatory infiltrate and no signs of malignancy. She was treated with pulse intravenous methylprednisolone at a dose of 500mg per day for five days and had rapid improvement. Her symptoms fully resolved after three months. This case highlights the need for better recognition and diagnosis of tumefactive demyelination, potentially avoiding unnecessary invasive diagnostic procedures such as brain biopsies.

Metronidazole-Induced Encephalopathy With Probable Crohn Encephalitis: A Case Report.

OBJECTIVES: Metronidazole central nervous system toxicity is a rare finding in patients receiving the medication. We report a peculiar case of metronidazole central nervous system toxicity in which both the underlying condition (Crohn disease) and the drugs used to treat it are potential causes of encephalopathy. METHODS: A 26-year-old female with 6-year history of Crohn's disease for 6 years presented acute-onset encephalopathy. We provide bibliographic evidence to support metronidazole toxicity and potential Crohn disease-associated neurologic involvement. RESULTS: The patient presented dystonia, cerebellar ataxia, and altered mental status. Magnetic resonance imaging of the brain revealed typical findings of metronidazole toxicity and white matter involvement of the centrum semiovale. Immunoelectrophoresis and immunofixation of serum and cerebrospinal fluid proteins were consistent with a systemic inflammatory process. We concluded on an association between drug toxicity and probable Crohn-associated neurologic involvement. Metronidazole was stopped and the patient was placed on vitamin therapy and diazepam to control dystonia. She deteriorated and was transferred to the intensive care unit where she expired. CONCLUSIONS: Acute behavioral changes in a young patient constitute an emergency and differential diagnoses should include infective, inflammatory, metabolic, and toxic causes. Metronidazole is a potential toxic etiology.

Hansen's Disease: A Practical Update on a Neglected Globally Significant Infection.

Leprosy is a great mimicker. It is caused by Mycobacterium leprae and Mycobacterium lepromatosis, together termed the M. leprae complex. Leprosy can result in systemic manifestations; however, the neurocutaneous syndrome is the most classic. There is a gap in recognizing the condition leading to misdiagnosis and delays in treatment. Leprosy remains an important cause of aesthetic and functional impairment. In this paper, we provide a practical review of leprosy touching on pathophysiology, clinical manifestation, classification, diagnostic approach and management of the condition in a way that can translate into clinical practice and help physicians better identify and manage potential cases of leprosy.

Sternal Puncture-Induced Acute Spinal Cord Syndrome in a Myeloma-Remissive Patient Revealing Pott Disease: A Case Report.

Cord compression is not a known complication of sternal puncture. We report the case of a patient with a history of multiple myeloma who presented acute onset paraplegia brought on during sternal puncture. Neuroimaging revealed focal spondylodiscitis and cord compression by an abscess. Neurosurgical decompression was not carried out on the patient because of her fragile general state of health and tardy consultation. Workup revealed the patient in remission from her multiple myeloma thus making decompressive radiotherapy unnecessary. The diagnosis of Pott disease was made by taking into account the clinical presentation, spine imaging and extra neurological imaging findings. Empiric anti-tuberculosis treatment was initiated which resulted in spectacular outcomes with a patient being able to walk with little aid by the end of her nine-month treatment course.

The prevalence of headache in the adult population of Morocco: a cross-sectional population-based study.

BACKGROUND: The series of population-based studies conducted by the Global Campaign against Headache has, so far, included Pakistan and Saudi Arabia from the Eastern Mediterranean Region. The Maghreb countries of North Africa, also part of this Region, are geographically apart and culturally very different from these countries. Here we report a study in Morocco. METHODS: We applied the standardised methodology of Global Campaign studies, with cluster-randomized sampling in regions of Morocco selected to be representative of its diversities. In three of these regions, in accordance with this methodology, we made unannounced visits to randomly selected households and, from each, interviewed one randomly selected adult member (aged 18-65 years) using the HARDSHIP structured questionnaire translated into Moroccan Arabic and French. In a fourth region (Fès), because permission for such sampling was not given by the administrative authority, people were randomly stopped in streets and markets and, when willing, interviewed using the same questionnaire. This was a major protocol violation. RESULTS: We included 3,474 participants, 1,074 (41.7%) from Agadir, 1,079 (41.9%) from Marrakech, 422 (16.4%) from Tétouan and 899 from Fès. In a second protocol violation, interviewers failed to record the non-participating proportion. In the main analysis, excluding Fès, observed 1-year prevalence of any headache was 80.1% among females, 68.2% among males. Observed 1-day prevalence (headache yesterday) was 17.8%. After adjustment for age and gender, migraine prevalence was 30.8% (higher among females [aOR = 1.6]) and TTH prevalence 32.1% (lower among females [aOR = 0.8]). Headache on ≥ 15 days/month (H15+) was very common (10.5%), and in more than half of cases (5.9%) associated with acute medication overuse (on ≥ 15 days/month) and accordingly diagnosed as probable medication-overuse headache (pMOH). Both pMOH (aOR = 2.6) and other H15+ (aOR = 1.9) were more common among females. In the Fès sample, adjusted prevalences were similar, numerically but not significantly higher except for other H15+. CONCLUSIONS: While the 1-year prevalence of headache among adults in Morocco is similar to that of many other countries, migraine on the evidence here is at the upper end of the global range, but not outside it. H15 + and pMOH are very prevalent, contributing to the high one-day prevalence of headache.

Chronic Cephalalgia-Parkinsonism Complex Revealing a Meningioma in a Young Patient: A Case Report.

The emergence of parkinsonism in a patient with an intracranial meningioma is indeed an uncommon occurrence. Here, we detail the case of a patient experiencing parkinsonian syndrome for four years without any observable clinical improvement following medical treatment. A magnetic resonance imaging (MRI) of the brain revealed a left intracranial meningioma. The successful complete surgical removal of the tumor led to the resolution of parkinsonian syndrome. The extent of the neoplasm and the surrounding peritumoral edema could potentially exert significant pressure, thereby compromising perfusion in the basal ganglia region. This clinical case serves as an exemplar, emphasizing the criticality of identifying specific red flags that necessitate further clinical investigations in the context of parkinsonian syndrome.

Severe acute polyradiculoneuritis revealing systemic lupus erythematosus: a case report.

Systemic Lupus Erythematosus (SLE) is a common disease with extremely heterogeneous neurological manifestations in its clinical expression. However, few cases have been reported in the last 50 years when the initial manifestation of SLE is Guillain-Barré syndrome (GBS). Our work highlights the importance of evoking SLE as a potential etiology in a patient presenting with acute polyradiculoneuritis. We report the case of a 41-year-old woman who presented with dyspnoea with a purely proxo-distal motor deficit in all four limbs with dermatological lesions such as generalized myxedema and alopecia. The clinical electrical and biological presentation confirms acute polyradiculoneuritis revealing systemic lupus erythematosus. The outcome was marked by clinical improvement, despite the severity of the clinical picture, after treatment with corticosteroid and cyclophosphamide boluses. In conclusion, neurological manifestations in lupus disease are common, whereas the form of acute polyradiculoneuropathy is very rare with a committed vital prognosis. Early diagnosis and management are essential.

Concomitant Guillain-Barré syndrome and cerebral venous thrombosis complicating a SARS-CoV-2 infection: a case report.

Cerebral venous thrombosis associated to acute inflammatory axonal polyneuropathy during infection with SARS-CoV-2 (coronavirus-2) is unusual. We describe the case of a 66-year-old patient with typical clinical and electrophysiological criteria of acute axonal motor neuropathy, who was positive for SARS-CoV-2. The symptoms started with fever associated with respiratory symptoms, and complicated one week later by headaches, and general weakness. The examination showed bilateral peripheral facial palsy, predominantly proximal tetraparesis, and areflexia with tingling of limbs were found. The whole was concomitant with the diagnosis of an acute polyradiculoneuropathy. Electrophysiologic evaluation confirmed the diagnosis. Cerebrospinal fluid examination showed albuminocytologic dissociation, and brain imaging revealed sigmoid sinus thrombophlebitis. Neurological manifestations improved during treatment with plasma exchange and anticoagulants. Our case draws attention to the occurrence of cerebral venous thrombosis and Guillain-Barré syndrome (GBS) in patients with COVID-19. The neuro-inflammation induced by the systemic immune response to infection, can lead to neurological manifestations. Further studies should be conducted on the full clinical spectrum of patients with COVID-19 with neurological symptoms.

Parkinsonism and chronic manganese exposure: Pilot study with clinical, environmental and experimental evidence.

Parkinsonism related to chronic Manganese exposure is notably due to focal lesions of the basal ganglia. Our study focused on epidemiological, clinical, toxicological and experimental aspects of Manganese-induced Parkinsonism in south of Morocco. It is a prospective study concerning the workers and the residents bordering on the 2 mines in the south of Morocco. The results of the study concerned 120 cases divided into 4 groups of patients: G1: 30 cases exposed to different incriminated toxic products, which present Parkinsonian signs, G2: 30 cases healthy and exposed, G3: 30 cases affected with Idiopathic Parkinson's disease, and G4: 30 cases healthy and unexposed (controls). The results from the first mine show that 5.7% of the sample developed Manganese-Induced Parkinsonism and this percentage is slightly higher (4.5%) than the second mine site. Chemical and biological analysis revealed high levels of Manganese. The majority of patients did not improve the clinical signs under L-dopa treatment. The authors underline the gravity of Manganese-induced Parkinsonism and propose a listing of the various exposures as well as a cartography of the regions of risk in Morocco.

Stroke in young adults: about 128 cases.

UNLABELLED: Ischemic stroke is rare in young adults, but it is genuinely a serious situation giving the fact that it touch a very active part of our society. We report a series of 128 cases. The purpose is to analyze the risk factors, etiologies and outcomes of ischemic stroke in young adults in Marrakesh. Retrospective study performed at the Neurology department Mohammed VI universitary hospital in Marrakesh interesting 128 patients. The diagnosis of ischemic stroke was assessed through clinical and radiological confrontation. RESULTS: The age of our patients varied from 18 to 45 years old, 76 males and 52 females giving a male: female ratio of 1:46. Hypertension was the first risk factor involved with 63 (49.2%) cases, followed by smoking with 52 (40.6%) patients. The causes of ischemic stroke were characterized by the predominance of the cardio embolic origin with 43 (33.5%) cases, the existence of 14 (11%) cases of syphilitic arthritis, and the 52 (40.6%) cases of unknown etiologies. The authors stress the difficulties faced on supporting ischemic stroke in southern Morocco in particular when concerned by the etiological finding and the rehabilitation after the acute phase of the stroke. Our study points out the high incidence of embolic heart disease in our context. The lack of neurologists, low coverage of the population and the underestimation by physicians are factors that can explain why ischemic stroke remain undiagnosed.
