RESUMO
Focal seizures with subjective auditory phenomena, known as auditory seizures, are uncommon and can include simple to complex auditory hallucinations. We present a case of a 59-year-old man who presented with motor and non-motor seizures. He had a four-month history of hearing things resembling continuous metallic sounds, pennies dropping into a bank, persistent music after radio cessation, and the sound of a passing train. Brain MRI showed multiple serpiginous flow voids in the right temporal lobes, consistent with an arteriovenous malformation that was confirmed eventually with a diagnostic brain angiogram. The etiology of the seizures was related to a structural lesion in the setting of a right temporal arteriovenous malformation (AVM). Treatment with 2000mg of levetiracetam twice daily and 300mg of oxcarbazepine twice daily improved symptoms, and subsequent stereotactic radiosurgery ablation successfully treated the AVM. Post-treatment MRI showed reduced visibility of parasitized vessels, with controlled generalized seizures but partial control of auditory seizures.
RESUMO
Leber hereditary optic neuropathy (LHON) is a mitochondrial disorder that presents with acute to subacute onset of unilateral progressive optic neuropathy, with sequential involvement of the fellow eye months to years later. The condition may be accompanied by neurological symptoms, including tremors, dystonia, seizures, or psychosis, in which case, it is termed LHON-plus. Here, we present the case of a 53-year-old man who was initially diagnosed with essential tremor but was later found to have LHON-plus after the onset of bilateral visual loss and a genetic panel. His essential tremor was refractory to standard pharmacological therapies, including propranolol, primidone, and topiramate. As a result, he elected to undergo bilateral deep brain stimulation (DBS) of the bilateral ventral intermediate nucleus of the thalamus with a dramatic improvement in symptoms. To our knowledge, this is the first case of essential tremor presenting in the context of LHON-plus to be treated successfully with DBS. While DBS has been applied in LHON-plus presenting with dystonia with limited success, our outcome suggests that there is promise in this approach and that more research is needed to evaluate it.
RESUMO
Hypereosinophilic syndrome (HES) is a rare condition characterized by elevated eosinophil counts (>1.5 x 109 on two consecutive measurements), which are of myeloid clonal in origin or are driven by excess cytokines. One subtype of HES exhibits the Fip1-like 1-platelet-derived growth factor receptor alpha (FIP1L1-PDGFRA) fusion gene, a gain-of-function mutation resulting in a hyperactive tyrosine kinase. HES, especially the FIP1L1-PDGFRA variant, exhibits an excellent response to chemotherapy with imatinib. In this report, we present a 38-year-old patient with no contributory past medical history who experienced sudden-onset fatigue, ataxia, visual changes, and headaches. He was found to have multiple small acute infarcts in his cerebrum and cerebellum. A stroke work-up, including transthoracic echocardiogram (TTE), transesophageal echocardiogram (TEE), and computed tomography angiography (CTA), did not yield insight into the origin of his infarcts. On CBC, he was consistently hypereosinophilic, and a bone marrow biopsy revealed hypercellularity and the FIP1L1-PDGFRA fusion gene, confirming the diagnosis of HES. The patient was treated first with methylprednisolone and then imatinib with excellent response. It appears that, in our patient, strokes were not of a thromboembolic nature but rather due to hypercoagulability. In this report, we advocate for considering HES and emphasize the importance of revisiting basic laboratory studies such as a CBC if the standard stroke workup fails to elucidate the mechanism behind ischemic strokes with an embolic pattern.
RESUMO
Neuro-ophthalmic manifestations of Wernicke encephalopathy (WE) are uncommon and vary from nystagmus, oculomotor palsies, anisocoria, and optic disc edema to vision loss. We describe a case of a 53-year-old woman presenting with subacute bilateral painless vision decline, lower-extremities weakness with impaired ambulation, headache, and abdominal pain. Neurological examination was pertinent for confabulation, bilateral decreased visual acuity with an absent blink to threat, absent afferent pupillary defect and fundus abnormalities, and significant allodynia in bilateral lower extremities. Besides elevated inflammatory marker with an erythrocyte sedimentation rate (ESR) of 130 mm/hr, her infectious, autoimmune, paraneoplastic, and neuromyelitis optica work-up was overall unremarkable. Brain MRI showed abnormal fluid-attenuated inversion recovery (FLAIR) signaling in bilateral mammillary bodies and around periaqueductal gray matter concerning WE. Due to concerns of Wernicke-Korsakoff syndrome (WKS), parenteral high-dose thiamine was initiated with significant clinical improvement. The patient was also later found to have a positive anti-myelin oligodendrocyte glycoprotein (MOG) antibody, which was deemed false positive given the atypical phenotype and symptomatic improvement with thiamine supplementation. This case encourages the consideration of vision loss as a manifestation of WKS, especially in patients who have risk factors. Testing serum levels of thiamine is strongly encouraged; however, initiating empiric treatment is advocated for high clinical suspicion due to its reversible nature and minimal risk for side effects.
RESUMO
Transverse myelitis (TM) is a frequently encountered inpatient neurological condition, usually with a broad differential of etiologies narrowed down by detailed history, temporal profile of symptom evolution, and pertinent diagnostic studies. We report a rare case of a 39-year-old man who presented with subacute onset of headaches and confusion, and three days later developed quadriplegia and areflexia. He was diagnosed with acute longitudinally extensive transverse myelitis (LETM) related to Epstein-Barr virus (EBV) superimposed on an initial presentation of streptococcal meningitis. As both etiologies are under-reported, we compare our case to the few similar cases in the literature to guide discussion of the clinical and radiologic findings of parainfectious TM related to EBV and streptococcal meningitis. Readers will have the challenge of attributing our patient's myelitis to one of these parainfectious sources and are encouraged to evaluate for rare infectious etiologies in acute settings.
RESUMO
Neuropsychiatric systemic lupus erythematosus (SLE) is a rare condition that has a multitude of mechanisms resulting in the emergence of variable clinical presentations. We describe a peculiar case of a 33-year-old female with a history of SLE presented with two weeks of fever, headache, and vomiting. On admission, she became obtunded and was emergently intubated. Initial lumbar puncture revealed pleocytosis (46% neutrophils, 320 corrected nucleated cells/µL), elevated protein (244 mg/dL; normal, 15-40 mg/dL), normal glucose (63 mg/dL), and negative cultures. Empiric acyclovir, ampicillin, ceftriaxone, and vancomycin were initiated without clinical improvement. Neurological examination was notable for limited ability to follow commands, vertical nystagmus, horizontal gaze palsy, diffuse hyperreflexia, and quadriparesis. Electroencephalogram (EEG) was consistent with diffuse encephalopathy. Brain magnetic resonance imaging demonstrated restricted diffusion and contrast enhancement in the posterior and central pons with edema. A cerebral angiogram showed no signs of vasculitis. Treatment with intravenous (IV) methylprednisolone 1 g and IV immunoglobulin 2 g/kg was initiated for five days. Despite these interventions, no discernible clinical improvement was observed, prompting the commencement of 500 mg/m2 cyclophosphamide and daily maintenance of IV methylprednisolone at 2 mg/kg. A repeat MRI three weeks later revealed a marked reduction in the size of the lesion involving the pons. The patient also improved clinically over the month with successful extubation, complete return in mental capabilities, and the ability to ambulate short distances with assistance.
RESUMO
INTRODUCTION: Paraneoplastic encephalitis (PE) represents a rare but significant complication in patients with testicular cancer (TC). Given the paucity of comprehensive literature on this topic, our review seeks to consolidate current knowledge and provide evidence-based recommendations for the diagnosis, prognosis, and management of PE in the context of TC. MATERIALS AND METHODS: In adherence to PRISMA guidelines, a systematic literature review was conducted from 1950 to April 2024 using PubMed. The search focused on articles where TC was identified as the primary etiology of PE. The Mixed Methods Appraisal Tool and the Oxford Centre for Evidence-Based Medicine's levels of evidence tool were employed for assessing study quality, and a thematic analysis was conducted to identify trends and patterns. RESULTS: Out of 91 articles identified, 29 met the inclusion criteria, encompassing 5 retrospective chart reviews, 3 case series, and 22 case reports. Findings indicate that PE symptoms can manifest at any stage of TC-before tumor detection, during treatment, or even years posttreatment. A notable observation was the frequent oversight of microscopic testicular tumors in ultrasound imaging, leading to diagnostic delays. The outcomes of PE in the context of TC were diverse, reflecting the heterogeneity of the studies included. CONCLUSION: PE, although rare, is a critical consideration in patients with TC presenting with neuropsychiatric symptoms. Early recognition and appropriate diagnostic workup, including consideration for microscopic neoplasms, are essential for timely intervention and improved patient outcomes.

OBJECTIVE: To examine recent literature and determine common clinical risk factors between antecedent traumatic brain injury (TBI) and the following development of opioid misuse and provide a framework for clinical identification of at-risk subjects and evaluate potential treatment implications within this association. DESIGN: A comprehensive systematic literature search of PubMed was conducted for articles between 2000 and December 2022. Studies were included if the human participant had any head trauma exposure and any chronic opioid use or dependence. After eligibility criteria were applied, 16 studies were assessed for thematic trends. RESULTS: Opioid use disorder (OUD) risks are heightened in cohorts with head trauma exposed to opioids while in the hospital, specifically with tramadol and oxycodone. Chronic pain was the most common predictor of long-term OUD, and continuous somatic symptoms associated with the TBI can lead to long-term opioid usage. Individuals who present with coexisting psychiatric conditions pose significantly more risk associated with a higher risk of long-term opioid use. CONCLUSION: Findings indicate that therapists and clinicians must consider a risk profile for persons with TBI and follow an integrated care approach to account for mental health, prior substance misuse, presenting somatic symptoms, and current medication regimen during evaluation.

Objetivo. La terapia de un inhibidor de la bomba de protones más dos antibióticos es el tratamiento más aceptado para la infección por el helicobacter pylori. Sin embargo, no hay consenso sobre su duración. El objetivo fue comparar los porcentajes de erradicación del esquema de omeprazol+amoxicilina+claritromicina administrados durante 7 vs 10 días. Metodología: Seleccionamos pacientes del Hospital Militar Central y Policlínico Peruano-Japonés con síntomas del tracto gastrointestinal superior y Helicobacter pylori. Excluimos aquellos con úlcera péptica. Para el diagnóstico se tomaron biopsias para la prueba de la ureasa, PCR, cultivo y coloración con plata. Empleamos omeprazol+claritromicina+amoxicilina, durante 7 días versus 10 días. Realizamos endoscopía control al mes de terminado el tratamiento, y utilizamos técnicas de biología molecular para diferenciar las recurrencias de las reinfeciones. Evaluamos l susceptibilidad a claritromicina. Resultados: Incluimos 36 pacientes en cada grupo. En ambos la erradicación fue igual: 86.1 por ciento (31/36). En varios pacientes en que persistió la bacteria se identificó la misma cepa que la inicial. El 91.18 por ciento de nuestras muestras fueron sensibles a claritromicina. Conclusiones: En el Perú la combinación de omeprazol+claritromicina+amoxicilina para erradicar la infección por el Helicobacter pylori da resultados superiores al 80 por ciento. El esquema de 7 y 10 días erradicó a la bacteria en el 86 por ciento de nuestros pacientes.

En el Perú se reporta con cierta frecuencia nuevos casos de Hepatitis Viral C (HVC) asintomática en pacientes con o sin antecedentes de transfusión. Sin embargo a pesar que en los últimos años, los despistajes serológicos han mejorado notablemente, aún persiste una población de politransfundidos con alto riesgo de HCV (hemodializados (HD) por ejemplo), representando un importante reservorio. Partiendo de esta premisa es que decidimos estudiar cuál es el riesgo que tiene la población de trabajadores de salud (TS) en el Perú como otro importante grupo de riesgo a la infección por por HCV. Se estudió 2,769 TS de 8 Hospitales Generales y 2 Clínicas privadas de la ciudad de Lima y de 7 Hospitales generales de cuatro ciudades importantes del Perú (Chiclayo, Trujillo, Arequipa y Cusco). Se estudió a todos aquellos trabajadores que por su especialidad, tienen mayor contacto con sangre y/o derivados (Cirugía, UCI, Traumatología, Ginecología, Gastroenterología, Hemodiálisis y Laboratorio-Banco de sangre BS). La población estudiada corresponde a 30 por ciento de los TS total de los servicios. Todos los sueros fueron procesados por el test EIA-3 (HCV-Cobas-Core, Lab. Roche, USA) los positivos fueron confirmados por RT-HCV (Amplicor-Roche) : los sueros positivos fueron confirmados por PCR y los positivos con carga viral alta se les hizo genotipaje HCV (Amplicor-Roche Diagnostic, IGEN Diagnostic USA). De los 2,769 trabajadores de salud estudiados en el Perú, 32 fueron positivos para anticuerpos HCV (1.16 por ciento del total). Lima presentó una prevalencia ligeramente mayor que los de provincia: 26 de 2,112 vs 6 de 657 ó 1.23 por ciento vs 0.91 por ciento respectivamente. El mayor riesgo lo tienen los profesionales con mayor contacto con sangre: 2 Médicos de HD, 5 enfermeras de HD y 3 técnicos de laboratorio-BS. Los médicos y las enfermeras comparten el mismo riesgo. Si separamos provincias de Lima, vemos que el mayor riesgo lo tienen ésta última (1.34 por ciento contra 1.07 por ciento en provincias). Existe un riesgo importante en trabajadores de salud y las cifras están ligeramente más elevadas de los valores que se sospechaban en el Perú (entre e. 0.4 y 1.0). Finalmente, podemos concluir que el grupo de mayor riesgo de HCV en trabajadores de salud (TS) están en el personal de hemodiálisis (3.1 por ciento), le siguen los de laboratorio (1.79 por ciento), el de cirugía (1.40 por ciento) y gastroenterología (0.8 por ciento).
