RESUMEN
PURPOSE OF REVIEW: Cannabis has been used since ancient times for medical and recreational research. This review article will document the validity of how medical cannabis can be utilized for chronic nonmalignant pain management. RECENT FINDINGS: Current cannabis research has shown that medical cannabis is indicated for symptom management for many conditions not limited to cancer, chronic pain, headaches, migraines, and psychological disorders (anxiety and post-traumatic stress disorder). Δ9-Tetrahydrocannabinol (THC) and cannabidiol (CBD) are active ingredients in cannabis that modulate a patient's symptoms. These compounds work to decrease nociception and symptom frequency via the endocannabinoid system. Research regarding pain management is limited within the USA as the Drug Enforcement Agency (DEA) classifies it as a schedule one drug. Few studies have found a limited relationship between chronic pain and medical cannabis use. A total of 77 articles were selected after a thorough screening process using PubMed and Google Scholar. This paper demonstrates that medical cannabis use provides adequate pain management. Patients suffering from chronic nonmalignant pain may benefit from medical cannabis due to its convenience and efficacy.

This case report delves into the unusual presentation of a 38-year-old female with a history of migraines, who initially presented with a severe right-sided headache and changes in vision in her right eye, which gradually improved. Although she had consulted with an eye specialist for these issues, she did not receive targeted treatment. This case underscores the necessity of vigilant evaluation and early intervention in a patient with seemingly benign symptoms, thereby highlighting the potential gravity of underlying conditions such as aneurysms. Our analysis and description of this case provide insights for clinicians to consider comprehensive assessment and to explore less common etiologies, resulting in improved patient outcomes.
RESUMEN
The standard convention for diagnosing bone fractures is through radiography. However, radiography can miss fractures depending on the type of injury or if human error is present. This may be due to improper patient positioning leading to superimposing bones being captured in the image, obscuring pathology. As of late, ultrasound has been gaining traction in terms of its utilization for diagnosing fractures, which radiography can miss at times. Here we present a case of a 59-year-old female who was diagnosed using ultrasound with an acute fracture that was initially missed on X-ray. We present a case of a 59-year-old female with a past medical history significant for osteoporosis who presented to an outpatient clinic for evaluation of acute left forearm pain. She reported sustaining a mechanical fall forward to the ground three weeks before bracing herself with her forearms, immediately developing left upper extremity pain lateralized to the forearm. Upon initial evaluation, forearm radiographs were obtained and showed no evidence of acute fractures. She then underwent a diagnostic ultrasound that showed an obvious fracture of the proximal radius, distal to the radial head. Upon reviewing initial radiograph films, it was evident that the proximal ulna was superimposed over the radius fracture as a proper neutral anteroposterior view of the forearm was not taken. The patient then underwent a computed tomography (CT) scan of her left upper extremity, which confirmed the presence of a healing fracture. We present a case in which ultrasound is an excellent adjunct when a fracture cannot be identified on plain film radiography. Its utilization should be well-known and considered more often in the outpatient setting.
RESUMEN
Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune condition characterized by recurrent episodes of optic neuritis (ON) and transverse myelitis. This case report aims to highlight the importance of considering atypical presentations of NMOSD when confronted with MRI-detected Wernicke's encephalopathy. The primary target in NMOSD is the aquaporin-4 (AQP4) protein, predominantly located on astrocyte surfaces. Antibodies binding to AQP4 can lead to astrocyte dysfunction and damage, contributing to NMOSD's distinctive pathology. The associated immune response and inflammation can cause secondary harm to various components of the central nervous system, including oligodendrocytes and neuronal axons. This inflammatory process results in perivascular demyelination and axonal injury, further aggravating neurological deficits in NMOSD. In this case, we present a 39-year-old female with no prior medical or surgical history who sought medical attention due to a three-week history of progressive eyelid heaviness and somnolence. NMOSD is an autoimmune condition primarily targeting the AQP4 protein, resulting in recurrent ON and transverse myelitis. The patient was initially misdiagnosed with myasthenia gravis due to somnolence and ptosis. Due to concerns about myasthenia gravis due to diffuse fatigue and bilateral ptosis, the patient was initially treated with intravenous immunoglobulin (IVIG) and admitted to the neurology service. On the first day of her hospitalization, MRI with and without contrast revealed extensive, non-enhancing T2-weighted-fluid-attenuated inversion recovery (T2-FLAIR) hyperintensities surrounding the third ventricle and affecting the periaqueductal grey, medial thalami, and mammillary bodies. There was also an interval increase in T2-FLAIR hyperintensity within the right medial temporal lobe, extending more posteriorly and inferiorly, abutting the temporal horn. Subsequent CSF encephalitis panel results showed positive West Nile virus (WNV) IgG but negative WNV IgM, and AQP4 antibodies were positive. Given the high specificity of AQP4 antibodies, the patient was diagnosed with neuromyelitis optica (NMO) encephalitis. This case underscores the importance of considering atypical presentations of NMO when confronted with MRI-detected Wernicke's encephalopathy. Since our patient primarily displayed somnolence and eye-related symptoms, neither NMO nor Wernicke's encephalopathy were initially considered in the differential diagnosis. Furthermore, despite MRI findings suggestive of Wernicke's encephalopathy, it was considered less likely due to the absence of thiamine deficiency and consistent denials by family members regarding alcohol use, gastrointestinal issues, or inadequate oral intake. This case underscores the importance of considering NMOSD in patients with atypical symptoms, even when initial presentations suggest other conditions. Timely diagnosis is crucial to prevent mismanagement and improve patient outcomes. Clinicians should maintain a high level of suspicion for NMOSD, especially when MRI findings do not align with the initial diagnosis, as early recognition and treatment can significantly impact patient care and prognosis.
RESUMEN
Takayasu's arteritis (TA) is a rare inflammatory disorder that affects large arteries, particularly the aorta and its main branches. TA is also known as a pulseless disease because it diminishes blood flow to the limbs and organs. The patient was a 17-year-old female whose prior medical history included a diagnosis of TA. She had been experiencing multiple syncopal episodes up to three times daily, lasting 10 seconds each. She was being managed outpatient with immunologic therapy and warfarin. She initially presented to a children's hospital with abdominal pain and an asymmetrical smile and was found to have a ruptured ovarian cyst. This case demonstrated that life-threatening complications of TA can occur as a result of otherwise unrelated and common circumstances. The patient was managed medically and then proceeded to surgery. The case further highlights the multidisciplinary team approach between medical and surgical specialties and weighing the risks and benefits of complications for the patient's long-term care. Early diagnosis and prompt initiation of appropriate therapy are essential for better outcomes. Clinicians should be aware of the nonspecific symptoms of TA and consider it in the differential diagnosis of young patients presenting with systemic symptoms and arterial insufficiency. The initial presentation of middle cerebral artery stroke in young women has been documented in prior literature, but most published cases present the medical management of the disease. Our patient's case was unique because medical management was insufficient, with surgical management pursued due to persistent symptomatic hypotension. The inciting event of this case, an ovarian rupture with retroperitoneal hemorrhage, represents a unique burden to watershed infarctions in this patient group. Further research is needed to understand the pathogenesis of TA better and to develop more effective treatment strategies for this challenging disease.
RESUMEN
The use of Edaravone, given orally, for the treatment of amyotrophic lateral sclerosis (ALS) was officially approved by the Federal Drug Association (FDA) in 2017. ALS is a rare and progressive degenerative disease that worsens over time. It attacks and destroys the nerve cells that control voluntary muscles, thus leading to weakness, eventual paralysis, and, ultimately death. Edaravone was given initially intravenously, but recent evidence shows better results with oral suspension. This narrative review is aimed to investigate the benefit of Edaravone for the management of ALS, compare it to Riluzole, discuss its mechanism of action, route of use, and side effects, and ultimately discuss future implications of this pharmacotherapy.
RESUMEN
The most common etiology of low back and neck pain is associated with spinal cord pathologies. Regardless of origin, low back and neck pain are some of the most common causes of disability worldwide. Mechanical compression due to spinal cord diseases, such as degenerative disc disorders, can lead to radiculopathy, which manifests as numbness or tingling and can progress to loss of muscle function. Conservative management, such as physical therapy, has not been proven effective in treating radiculopathy, and surgical treatments have more risks than benefits for most patients. Epidural disease-modifying medications, such as Etanercept, have been recently explored due to their minimal invasiveness and direct effects on inhibiting tumor necrosis factor-α (TNF-α). Therefore, this literature review aims to evaluate epidural Etanercept's effect on radiculopathy caused by degenerative disc diseases. Epidural Etanercept has been shown to improve radiculopathy in patients with lumbar disc degeneration, spinal stenosis, and sciatica. Further research is needed to compare the effectiveness of Etanercept with commonly used treatments such as steroids and analgesia.
RESUMEN
Strokes are the second leading cause of death and disability worldwide. The brain injury resulting from stroke produces a persistent neuroinflammatory response in the brain, resulting in a spectrum of neurologic dysfunction affecting stroke survivors chronically, also known as post-stroke pain. Excess production of tumor necrosis factor alpha (TNF alpha) in the cerebrospinal fluid (CSF) of stroke survivors has been implicated in post-stroke pain. Therefore, this literature review aims to assess and review the role of perispinal etanercept in the management of post-stroke pain. Several studies have shown statistically significant evidence that etanercept, a TNF alpha inhibitor, can reduce symptoms present in post-stroke syndrome by targeting the excess TNF alpha produced in the CSF. Studies have also shown improvements in not only post-stroke pain but also in traumatic brain injury and dementia. Further research is needed to explore the effects of TNF alpha on stroke prognosis and determine the optimal frequency and duration of etanercept treatment for post-stroke pain.
RESUMEN
Anticoagulation therapy is critical to avoiding thrombotic events in patients following cranial surgery. Although Aspirin, Plavix, and Aggrastat are used as anticoagulants for this purpose, there is no consensus on which agent is the most effective and safe. In this comparative study, we analyze the current evidence on the efficacy and safety of these three anticoagulants in the context of cranial surgeries. This review focuses on the advantages and disadvantages of each anticoagulant, such as its pharmacokinetics, indications, contraindications, and possible consequences. The outcomes of this study will help physicians choose the best anticoagulant for their patients based on individual patient characteristics and the kind of cranial procedure. Aggrastat's potential to be included as a recommended anticoagulant for cranial procedures warrants further study.
RESUMEN
This case report presents a unique case of a difficult differential diagnosis of autoimmune encephalitis (AE) in the setting of Mycoplasma pneumoniae. A 40-year-old female with a history of Hashimoto thyroiditis, polycystic ovarian syndrome, and a lower respiratory infection presented to the emergency department with new-onset progressive neurological symptoms. These included generalized tonic-clonic seizure and worsening respiratory status that required intubation and tracheostomy. Blood cultures returned positive for M. pneumoniae. We concluded this to be a mixed diagnosis case of anti-glutamic acid decarboxylase 65 (anti-GAD65), Bickerstaff's brainstem encephalitis (BBE), Hashimoto's encephalopathy (HE), and Miller Fisher Syndrome (MFS) concurrently in the setting of M. pneumoniae. Initial treatment with intravenous immunoglobulin showed minimal improvement; however, subsequent treatment with plasmapheresis proved to be beneficial for the patient. Over the course of the plasma exchange therapy (PLEX), the patient slowly became more alert, attentive, and verbal. She was able to answer simple questions and follow commands. Common trends of age, gender, presenting symptoms, associated antibodies, and sessions of PLEX in different AE diseases were identified through a literature review. Only 69.7% of the cases implemented PLEX or plasmapheresis. Currently, there is no standard protocol for the treatment of AE. Our case report aims to present a clinically complicated example of AE and to provide further evidence to support PLEX as an important therapeutic option.
RESUMEN
Fragile X syndrome (FXS) is noted to be the leading cause of inherited intellectual disabilities and is caused by expansive cytosine-guanine-guanine (CGG) trinucleotide repeats in the fragile X mental retardation 1 gene (FMR1). FXS can display a wide range of behavioral problems in addition to intellectual and developmental issues. Management of these problems includes both pharmacological and non-pharmacological options and research on these different management styles has been extensive in recent years. This narrative review aimed to collate recent evidence on the various management options of behavioral problems in FXS, including the pharmacological and non-pharmacological treatments, and also to provide a review of the newer avenues in the FXS treatment.
RESUMEN
Kleine-Levin syndrome (KLS) is characterized by episodes of hypersomnia. Additionally, these patients can present with hyperphagia, hypersexuality, abnormal behavior, and cognitive dysfunction. Functional neuroimaging studies such as fMRI-BOLD, Positron Emission Tomography (PET) or SPECT help us understand the neuropathological bases of different disorders. We conducted a systematic review to investigate the neuroimaging features of KLS patients and their clinical correlations. This systematic review was conducted by following the Meta-Analysis of Observational Studies in Epidemiology (MOOSE) and PRISMA protocol reporting guidelines. We aim to investigate the clinical correlation with neuroimaging among patients with KLS. We included only studies written in the English language in the last 20 years, conducted on humans; 10 studies were included. We excluded systematic reviews, metanalysis, and case reports. We found that there are changes in functional imaging studies during the symptomatic and asymptomatic periods as well as in between episodes in patients with K.L.S. The areas most reported as affected were the hypothalamic and thalamic regions, which showed hypoperfusion and, in a few cases, hyperperfusion; areas such as the frontal, parietal, occipital and the prefrontal cortex all showed alterations in cerebral perfusion. These changes in cerebral blood flow and regions vary according to the imaging (SPECT, PET SCAN, or fMRI) and the task performed while imaging was performed. We encountered conflicting data between studies. Hyper insomnia, the main feature of this disease during the symptomatic periods, was associated with decreased thalamic activity. Other features of K.L.S., such as apathy, hypersexuality, and depersonalization, were also correlated with functional imaging changes. There were also findings that correlated with working memory deficits seen in this stage during the asymptomatic periods. Hyperactivity of the thalamus and hypothalamus were the main features shown during the asymptomatic period. Additionally, functional imaging tends to improve with a longer course of the disease, which suggests that K.L.S. patients outgrow the disease. These findings should caution physicians when analyzing and correlating neuroimaging findings with the disease.
RESUMEN
Primary Central Nervous System Lymphoma (PCNSL) is a rare variant of Non-Hodgkin Lymphoma (NHL) representing 1-2% of all NHL cases. PCNSL is defined as a lymphoma that occurs in the brain, spinal cord, leptomeninges, or eyes. Efforts to treat PCNSL by traditional chemotherapy and radiotherapy have generally been unsuccessful as a significant proportion of patients have frequent relapses or are refractory to treatment. The prognosis of patients with Refractory or Relapsed (R/R) PCNSL is abysmal. The optimal treatment for R/R PCNSL is poorly defined as there are only a limited number of studies in this setting. Several studies have recently shown that ibrutinib, a Bruton tyrosine kinase (BTK) inhibitor, has promising results in the treatment of R/R PCNSL. However, these are preliminary studies with a limited sample size. In this systematic review, we explored and critically appraised the evidence about the efficacy of the novel agent ibrutinib in treating R/R PCNSL.
RESUMEN
Neurofibromatosis type 1 (NF-1), also known as Von Recklinghausen's disease, is an autosomal-dominant disease that is characterized by high-frequency mutations leading to multiple benign tumors called neurofibromas and café au lait spots on the skin. Although NF-1 mainly affects the nervous system, it can have multisystem involvement as well, associated with the cardiovascular, orthopedic, gastrointestinal, and dermatologic systems. Psychiatric complications like anxiety, dysthymia, and depression have also been reported in patients with NF-1. The prevalence of this disorder is one in 3,000 births. NF-1 patients have a higher prevalence of seizures compared to the general population. A 20-year-old male with a diagnosis of NF-1 at the age of three months presented to the emergency room (ER) of a local hospital for the evaluation of an unwitnessed seizure characterized by loss of consciousness and bladder control. MRI of the brain without contrast revealed hyperintensities in the mesial temporal lobe bilaterally, with a hyperintense FLAIR lesion in the splenium of the corpus callosum. The patient exhibited sudden aggression and combativeness while in the ER and also experienced a second seizure, which prompted immediate intubation. A second MRI with contrast confirmed the presence of the lesion. The patient also underwent electroencephalogram (EEG) monitoring later during his hospital stay, the results of which were unremarkable. This case report discusses an adult male with NF-1 and a tumor of the splenium of the corpus callosum. The displayed imaging suggested a possible etiology for high seizure frequency in patients with NF-1 compared to the general population.
RESUMEN
Citrullinemia refers to a family of autosomal recessive disorders involving the urea cycle. Three forms exist, which have different implications. Type I citrullinemia exists in both mild and severe forms. It arises due to mutations with argininosuccinate synthase leading to accumulation of ammonia and producing symptoms of lethargy, poor feeding, and seizures. Type II citrullinemia occurs due to citrin mutations involved in the urea cycle transport or during neonatal cholestasis. Management of both conditions requires low-protein diets along with arginine, sodium benzoate, and sodium phenylacetate. While traditional treatment shows improved outcomes, modifications may be necessary depending on a patient's presentation. We present a unique case of a 19-year-old wheelchair-bound female with a past medical history of heterozygous type I citrullinemia, seizures, and chronic encephalopathy presented to a local children's hospital for evaluation of altered mental status with a lethargic mental state. She was initially found to have an ammonia level of 329 µmol/L and choledocholithiasis on admission. Dietary modification with intravenous dextrose and intralipids with oral lactulose saw improvement in her labs. However, her ammonia level increased to 381 µmol/L despite such interventions. Intensive care was required to normalize her serum ammonia level and clear her for a magnetic resonance cholangiopancreatography (MRCP). We present a unique case of heterozygous type I citrullinemia with some overlap with type II citrullinemia features. Further studies are needed to understand better the observed unique presentation and long-term clinical implications associated with the disease.
RESUMEN
Pediatric cerebral venous sinus thrombosis (CVST) is a rare complication of ulcerative colitis. Ulcerative colitis is a form of inflammatory bowel disease which accentuates hypercoagulation, thereby leading to thrombosis. Herein, we report a case of a 10-year-old girl who presented with chief complaints of headache, confusion, and new-onset seizure activity for one month as progressively worsening sequelae of ulcerative colitis. Her magnetic resonance venogram confirmed thrombosis in the right transverse, sigmoid, and superior sagittal sinus. The acute ulcerative colitis flare was managed with a short course of steroids and anti-inflammatory monoclonal antibody, and CVST got improved with low-molecular-weight heparin (LMWH). Our study emphasizes the emergence of fatal complications of ulcerative colitis in the pediatric population. It also endorses the pivotal role of thromboprophylaxis with LMWH in pediatric CVST patients. Nevertheless, further studies are required to standardize the use of LMWH in clinical practice.
RESUMEN
Chiari malformations (CMs) are a group of disorders involving deformities of the posterior fossa and hindbrain. There are seven types of CMs: 0, I, 1.5, II, III, IV, and V. CMIII is a very infrequent disorder characterized by low occipital or superior cervical encephalocele and inferior displacement of the brainstem. Here we present a unique case of CMIII associated with cleft palate, abnormal midbrain, and abnormal corpus callosum. CMIII is a very rare condition, which needs to be reported. This study primarily aims to compare our case to other cases of CMIII. We did not find another case with cleft palate and CMIII. There are only a few cases reported of CMIII. That is why it is vital to report each of these cases. Among reported CMIII cases, our case is unique regarding the co-occurrence of cleft palate. There seems to be an embryological link between these two conditions. However, cleft palate is a relatively common congenital defect, which means that the co-occurrence could be just a coincidence as well. Further research is warranted to broaden the information of this extremely rare syndrome.
RESUMEN
Griscelli syndrome (GS) is a rare syndrome characterized by hypopigmentation, immunodeficiency, and neurological features. The genes Ras-related protein (RAB27A) and Myosin-Va (MYO5A) are involved in this condition's pathogenesis. We present a GS type 1 (GS1) case with developmental delay, hypotonia, and refractory seizures despite multiple medications, which included clobazam, cannabinol, zonisamide, and a ketogenic diet. Lacosamide and levetiracetam were added to the treatment regimen, which decreased the seizures' frequency from 10 per day to five per day. The patient had an MYO5A mutation and, remarkably, a deletion on 18p11.32p11.31. The deletion was previously reported in a patient with refractory seizures and developmental delay. We reviewed all cases of GS that presented with seizures. We reviewed other cases of GS and seizures described in the literature and explored possible seizure mechanisms in GS. Seizure in GS1 seems to be related directly to the MYO5A mutation. The neurological manifestations in GS2 seem to be caused indirectly by the accelerated phase of Hemophagocytic syndrome (HPS), which is characteristic of GS2. By having the MYO5A gene mutation combined with the 18p11.32p11.31 deletion, the prognosis and severity of the patient's condition are poor. This is the first report of GS1 with a deletion in 18p11.32p11.31.
RESUMEN
Pyruvate carboxylase (PC) converts pyruvate to oxaloacetate, which is an important step in gluconeogenesis. Pyruvate carboxylase deficiency (PCD) is a rare inherited metabolic disorder characterized by movement disorders, neurologic disturbances, hypoglycemia, lactic acidosis, hyperammonemia, and elevated levels of pyruvate and alanine in plasma. The prognosis for PCD is poor. Most children die within the first six months of life, and those who survive longer have neurological damage and mental disability. This is due to the accumulation of lactic acid and toxic components in the blood. Here we describe the case of a 21-month-old male presenting with abnormal movements and new-onset seizures. His family history is relevant because of parental consanguinity. A genetic analysis showed a novel mutation, homozygous c. 2630A>G (p. Gln877Arg) variant, in the PC gene, a mutation not previously described in the English literature.
RESUMEN
Hypoxic-ischemic encephalopathy (HIE) typically manifests in the neonatal period. The degree of hypoxia following intrapartum asphyxia determines the structural changes in the brain, which can cause functional deficits in the affected child leading to developmental deficits and recurrent seizures. Management requires physical therapy, occupational therapy, and anti-seizure medications. We present a rare case of an 11-year-old female with a past medical history of epilepsy and cerebral atrophy secondary to hypoxic injury at birth. The patient presented to the hospital following a witnessed seizure and loss of consciousness for one hour. Given the past medical history and clinical findings, it was determined that a mild-to-moderate encephalopathic process resulted in a lower seizure threshold. HIE can manifest beyond the neonate years mainly due to the structural changes within the brain. Therefore, it is essential to understand aspects of HIE beyond the neonate years to manage this condition for a better patient outcome.
