RESUMO

When we reflect on medical education as a whole, novelty in structure and content promotes growth and enhances student outcomes. The teaching of neurology is no different and presents a more unique hurdle in its instruction considering the well-described phenomenon of neurophobia. With the burden of neurological diseases on the rise, there is a heightened demand for medical educators to understand the possible causes of this educational misalignment and implement solutions necessary to ensure adequate education of students. In this study, we describe a novel approach to neurology education for second-year medical students to stimulate neurophilia, incorporating evidence-based approaches within the identified areas-Active Learning Pedagogies, Diagnostic and Clinical Reasoning, Use of Technology, Field Exposure and Mentorship, and Innovation. Students demonstrated superior academic performance on the National Board of Medical Examiners (NBME) neurology assessments and generally positive feedback on the use of innovative approaches to teaching and learning. Overall, we propose this method of teaching neurology as a model educational platform that aims to reduce neurophobia and promote neurophilia.

RESUMO

Statin medications act by inhibiting the enzyme hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase (HMGCR), thus decreasing hepatic cholesterol synthesis. They are considered the mainstay treatment of hypercholesterolemia due to their tremendous efficacy and mortality benefit. Although generally well tolerated, statins may adversely affect skeletal muscle resulting in side effects ranging from mild myalgia to life-threatening necrotizing myositis. Statin-induced necrotizing autoimmune myositis is a rare yet devastating adverse effect that may occur shortly after initiation of therapy or after several years of use. Unfortunately, medication discontinuation has shown no impact on prevention or alleviation of symptoms. Though there is currently no definitive guidance for the treatment of this condition, corticosteroids are generally considered to be first line, via high-dose oral prednisone or intravenous methylprednisolone. In this case report, we discuss the case of a 72-year-old male with an unusual presentation of statin-induced necrotizing autoimmune myositis: dysphagia, weakness, and weight loss. His diagnosis was confirmed by muscle biopsy indicating necrotizing myositis and his serum was found to be strongly positive for anti-HMG-CoA reductase antibodies. This patient had a very brief history of statin use, but his primary care provider discontinued the medication a couple of months prior to symptom onset due to elevated liver function tests. He was treated with aggressive intravenous fluid hydration and intravenous corticosteroids during an extended inpatient hospital stay. He was discharged to a rehabilitation facility. This report demonstrates the importance of creating a wide differential for patients who present with fatigue, generalized weakness, and dysphagia. It is essential to always consider statin-induced necrotizing myositis if a patient has a history of statin use, even if the statin has been discontinued. Necrotizing myositis demands timely diagnosis and management to improve mortality.

RESUMO

Patients with a long-standing history of immunosuppression are at significantly increased risk of opportunistic infections. One such group of organisms that may cause these types of infections includes the Nocardia genus, a gram-positive, filamentous rod that demonstrates a branching pattern, is urease-producing and has acid-fast properties. The disease profile of Nocardia varies with manifestations ranging from cutaneous infection to severe pulmonary or central nervous system (CNS) infections, and rarely, osteomyelitis. In this case report, we present an 87-year-old female with persistent left gluteal and lumbar pain, generalized body aches, chills, and fevers diagnosed with Nocardia asiatica osteomyelitis of the pelvis, likely secondary to dissemination from pulmonary cavitary disease in an immunosuppressed host with chronic neutropenia. On magnetic resonance imaging (MRI), the patient was found to have heterogeneous enhancement, central necrosis, and loss of cortical margins of the left iliac wing, alongside a rim-enhancing soft tissue mass from the left iliac bone into the left gluteal soft tissues and left paraspinal musculature representing an abscess. She was promptly treated with surgical irrigation and drainage with surgical wound cultures growing Nocardia asiatica. She received treatment with trimethoprim-sulfamethoxazole antibiotics with symptom improvement and is following up with an infectious disease physician outpatient. Management of osteomyelitis, like in this case, involves long-term antibiotics with the potential need for surgical intervention. There are few reported cases of extrapulmonary Nocardia infections, particularly osteomyelitis, demonstrating the importance of their inclusion in the literature to better serve patients to allow for timely intervention for rare and life-threatening conditions. In immunocompromised hosts, the differential diagnosis should include opportunistic infections and less common pathogens, especially in those with atypical presentations, including gluteal and leg pain.

RESUMO

The cranial nerves (CNs) are responsible for multiple functions, including extraocular mobility, facial sensation and movement, hearing, mastication, tongue movement and sensation, and swallowing. Beyond these vital roles, they can also demonstrate importance in their diagnostic value. Isolated or combined palsies provide insights into potential localizations and various underlying etiologies, including stroke, tumor, and infections that may guide further neurological evaluation. CN VI, the abducens nerve, singularly innervates the lateral rectus muscle, which is responsible for the abduction of the eyes. Despite its long anatomic trajectory, making it susceptible to intracranial injury, an isolated abducens nerve palsy is extremely rare. The most common clinical presentation includes headache, diplopia, and the inability to abduct the afflicted eye. This case report introduces a 71-year-old female with a medical history of malignancy and pancytopenia who presented to the emergency room with complaints of ear pain and swelling and subsequently developed diplopia secondary to unilateral CN VI palsy. Magnetic resonance imaging (MRI) revealed isolated sphenoid sinusitis for which she was clinically asymptomatic. She was treated with a regimen of ampicillin-sulbactam, an oral anti-inflammatory agent, and a tapered course of methylprednisolone with a rapid and complete resolution of the abducens nerve palsy and sinusitis. Acute isolated diplopia is an unusual neurologic condition prompting the need for rapid and thorough investigation. Although exceedingly rare and infrequently cited in the literature, isolated abducens nerve palsies secondary to sphenoid sinusitis should be entertained in the differential diagnosis of this presentation.

RESUMO

Brain tumors in adults may be infrequent when compared with other cancer etiologies, but they remain one of the deadliest with bleak survival rates. Current treatment modalities encompass surgical resection, chemotherapy, and radiotherapy. However, increasing resistance rates are being witnessed, and this has been attributed, in part, to cancer stem cells (CSCs). CSCs are a subpopulation of cancer cells that reside within the tumor bulk and have the capacity for self-renewal and can differentiate and proliferate into multiple cell lineages. Studying those CSCs enables an increasing understanding of carcinogenesis, and targeting CSCs may overcome existing treatment resistance. One approach to weaponize new drugs is to target these CSCs through drug repurposing which entails using drugs, which are Food and Drug Administration-approved and safe for one defined disease, for a new indication. This approach serves to save both time and money that would otherwise be spent in designing a totally new therapy. In this review, we will illustrate drug repurposing strategies that have been used in brain tumors and then further elaborate on how these approaches, specifically those that target the resident CSCs, can help take the field of drug repurposing to a new level.

RESUMO

This study was performed to assess the feasibility and accuracy of ultrasound guided fine needle aspiration biopsy for axillary staging in invasive breast cancer. Data were collected prospectively from June 2005 to June 2006. In all, 197 patients with invasive breast cancer and clinically nonsuspicious axillary lymph nodes were included. Patients with suspicious nodes on ultrasound had fine needle aspiration biopsy. Those with fine needle aspiration biopsy positive for malignancy were planned for axillary nodes clearance otherwise they had sentinel node biopsy. Patients (41) had ultrasound guided fine needle aspiration biopsy. Three cases were excluded for being nonconclusive. Postoperative histology showed 18/38 cases (47.4%) axillary lymph nodes positive and 20/38 cases (52.6%) axillary nodes negative. Ultrasound guided fine needle aspiration biopsy was positive in 8/38 cases (21.1%), negative in 30/38 cases (78.9%). The sensitivity of ultrasound guided fine needle aspiration biopsy was found to be 47.1%, specificity 100%, positive predictability 100%, negative predictability 70%, and overall accuracy 76.3%. Ultrasound guided fine needle aspiration biopsy was found to be more accurate and sensitive when two or more nodes were involved, raising the sensitivity to 80% and negative predictability to 93.3%. Preoperative axillary staging with ultrasound guided fine needle aspiration biopsy in invasive breast cancer patients is very beneficial in diagnosing nodes positive cases. These cases can be planned for axillary lymph nodes clearance straightaway therefore saving patients from undergoing further surgery as well as time and resources.
