Myasthenia Gravis Masquerading as an Idiopathic Unilateral Facial Paralysis (Bell's Palsy)-A Very Rare and Unique Clinical Find.

Myasthenia gravis (MG) is an uncommon autoimmune neuromuscular junction disorder manifesting as fluctuating weakness of skeletal muscles. To add to its repertoire of mimicking a wide range of neurological disorders, the present case report is, to the best of our knowledge, the very first to describe MG masquerading as an idiopathic unilateral facial paralysis (Bell's palsy, BP). Our case report is distinct, highlights a novel clinical occurrence, offers new insights of how different neurological disorders may overlap with each other, and reminds neurologists to have a very broad and thorough comprehension for effective diagnoses and treatment plans. Several other conditions that produce facial nerve palsy identical to BP have also been discussed.

Amyotrophic Lateral Sclerosis with Frontotemporal Dementia in the Presence of C9orf72 Repeat Expansion-A Case Report.

Amyotrophic lateral sclerosis and frontotemporal dementia are significant neurodegenerative illnesses with possible genetic predispositions. The C9orf72 gene and the GGGGCC repeat expansions of it are reported to have a causative role in the expression of these conditions. We report a case of a patient with autosomal dominant amyotrophic lateral sclerosis and frontotemporal dementia (ALS-FTD) in the presence of C9orf72 repeat expansion. We believe our case further supports the theory that the presence of C9orf72 repeat expansion in patients with a family history of amyotrophic lateral sclerosis and/or frontotemporal dementia significantly increases their risk of developing either or both diseases. The development of antisense oligonucleotides that might target GGGGCC RNA sequences theoretically may have a therapeutic role in mitigating the clinical expression of these illnesses.

Role of eslicarbazepine in the treatment of epilepsy in adult patients with partial-onset seizures.

Eslicarbazepine is a new dibenzazepine antiepileptic agent. It is a high affinity antagonist of the voltage-gated sodium channel. It is closely related to both carbamazepine and oxcarbazepine. Eslicarbazepine has similar affinity to inactivated sodium channels (channels in just activated neurons) as carbamazepine, and greater efficacy in animal models of seizure than oxcarbazepine. In human placebo-controlled trials of a single daily dose of eslicarbazepine added to other anti-epileptic agents, significant seizure reductions occurred with 800 and 1200 mg daily, with nearly half of the patients experiencing a greater than 50% reduction in seizure frequency. Adverse events (AEs) occurred in over 50% of patients receiving therapeutic doses of eslicarbazepine (compared to 31.4%-44.7% of placebo-treated subjects), but were generally mild or moderate. Eight to 19.6% of eslicarbazepine treated patients discontinued due to AEs (compared to 3.9%-8.5% of placebo-treated subjects). In these patients receiving combination anticonvulsant therapy, the most common AEs were dizziness, nausea and vomiting, somnolence, and diplopia. Eslicarbazepine is an effective and reasonably well-tolerated adjunct in patients with suboptimal control of their partial seizures.

Diagnostic nerve ultrasound in Charcot-Marie-Tooth disease type 1B.

Ultrasound is emerging as a useful tool for evaluation of neuromuscular conditions, because it can provide high-resolution anatomic information to complement electrodiagnostic data. There have been few studies in which ultrasound was used to assess the peripheral nerves of individuals with Charcot-Marie-Tooth (CMT) disease and none involving CMT type 1B. In this study we compared nerve cross-sectional area in individuals from a single large family with CMT 1B with normal, healthy controls. We also assessed for cranial nerve enlargement in those with CMT 1B with cranial neuropathies compared to those with CMT 1B without cranial neuropathies. Individuals with CMT 1B have significantly larger median and vagus nerves than healthy controls, but no difference was seen in cranial nerve size between those with versus those without cranial neuropathies. This is the first study to characterize the ultrasonographic findings in the peripheral nerves of individuals with CMT 1B.

Cross-sectional area reference values for nerve ultrasonography.

Ultrasound allows for a non-invasive structural assessment of nerves, muscles, and surrounding tissues, and therefore it is increasingly being used as a supplement to traditional electrodiagnostic studies. As investigators have begun to use ultrasound to explore peripheral nerves, it has become clear that conditions such as entrapment, hereditary neuropathies, acquired neuropathies, trauma, and nerve tumors result in an increase in nerve cross-sectional area. Reference values have not been published for the cross-sectional area of many nerves commonly studied in diseases of the peripheral nervous system, so our goal was to obtain reference values for the nerve cross-sectional area at the following sites: radial at antecubital fossa; radial at distal spiral groove; musculocutaneous in upper arm; trunks of the brachial plexus; vagus at carotid bifurcation; sciatic in distal thigh; tibial in popliteal fossa; tibial in proximal calf; tibial at ankle; peroneal in popliteal fossa; peroneal at fibular head; and sural in distal calf. Mean cross-sectional area, as well as side-to-side differences, are reported for each site, and qualitative data are provided to guide imaging at each site. The information provided in this study should serve as the starting point for quantitatively evaluating these nerve sites with ultrasound.

Ultrasound in the diagnosis of a median neuropathy in the forearm: case report.

BACKGROUND: Electrodiagnostic studies are traditionally used in the diagnosis of focal neuropathies, however they lack anatomical information regarding the nerve and its surrounding structures. The purpose of this case is to show that high-resolution ultrasound used as an adjunct to electrodiagnostic studies may complement this lack of information and give insight to the cause. CASE PRESENTATION: A 60-year-old male patient sustained a forearm traction injury resulting in progressive weakness and functional loss in the first three digits of the right hand. High-resolution ultrasound showed the presence of an enlarged nerve and a homogenous soft-tissue structure appearing to engulf the nerve. The contralateral side was normal. Surgery revealed fibrotic bands emanating from the flexor digitorum profundus muscle compressing the median nerve thus confirming the ultrasound findings. CONCLUSION: A diagnostically challenging case of median neuropathy in the forearm is presented in which high-resolution ultrasound was valuable in establishing an anatomic etiology and directing appropriate management.

Programmatic curricular outcomes assessment at colleges and schools of pharmacy in the United States and Puerto Rico.

OBJECTIVES: To categorize the manner in which programmatic curricular outcomes assessment is accomplished, identify the types of assessment methodologies used, and identify the persons or groups responsible for assessment. METHODS: A self-administered questionnaire was mailed to 89 institutions throughout the United States and Puerto Rico. RESULTS: Sixty-eight of 89 surveys (76%) were returned. Forty-one respondents (60%) had a written and approved plan for programmatic curricular outcomes assessment, 18% assessed the entire curriculum, and 57% had partial activities in place. Various standardized and institution-specific assessment instruments were employed. Institutions differed as to whether an individual or a committee had overall responsibility for assessment. CONCLUSION: To move the assessment process forward, each college and school should identify a person or group to lead the effort. Additional validated assessment instruments might aid programmatic assessment. Future studies should identify the reasons for selecting certain assessment instruments and should attempt to identify the most useful ones.
