To cite: Carswell C, Northey LC, Davies L, et al. Pract Neurol 2015;15:76–79. A 72-year-old man presented with sudden onset of right-sided facial muscle weakness and slurred speech and a 3-day history of fevers, myalgia and sore throat. There was no hyperacusis, change in taste or lacrimation. His history included untreated hepatitis C diagnosed 10 years before, but quiescent at his annual live...

If the characteristics of s-boxes of the SAFER family of ciphers are examined for the criteria of strict avalanche, bit independence, and XOR table distribution, experiments show that the “exponentiating” s-box has a weakness for an input difference of 128 (=100000002) and the “logarithm-taking” s-box has a weakness for an input difference of 253 (=111111012). However, since these experiments a...

Plasmacytoma is a rare disease, which afflicts 2 to 3 people per every 100,000 of the general population. Solitary plasmacytoma accounts for 5% of the plasma cell neoplasm. Solitary plasmacytoma of the bone appears more vividly in the axial skeleton (25-60%), which has the red marrow and usually affects the thoracic vertebrae. We report a case of 54-year-old man who has a chest pain on the righ...

Introduction: Surviving extreme hypercapnia from muscular respiratory failure has been only rarely reported. Case Report: A 66­year­old male developed slowly progressive weakness of the lower limbs since one year resulting in recurrent falls and later dysarthria, weakness of the left intrinsic hand muscles, general wasting, brisk tendon reflexes, and symmetric stocking type pall­hypaesthesia. E...

A healthy 58-year-old man presented to the emergency department with right arm weakness first noticed while playing hockey that day. He could not recall the onset of injury, but endorsed several weeks of antecedent intermittent right shoulder discomfort. Examination revealed a deformity of the right biceps brachii with distal bunching of the muscle (Figure). Tenderness existed along the proxima...

Respiratory failure is a common complication of acute neuromuscular disease and high cervical cord lesions and should be monitored by measuring forced vital capacity and respiratory rate. Urgent imaging is mandatory if there is any clinical suspicion of spinal cord disease. Treatment of Guillain-Barré syndrome with plasma exchange or intravenous immunoglobulin (IVIg) speeds up the rate of recov...

Paralysis of the diaphragm occurring as a result of damage to the phrenic nerves during thoracic and neck surgery is well recognised.' 2 It is likely that weakness, as opposed to complete paralysis, of the diaphragm could occur after less severe trauma to the phrenic nerves. We describe a patient who developed bilateral diaphragm weakness after complicated surgery on a cervical disc, with subse...

Chronic Inflammatory Demyelinating Polyneuropathy is an autoimmune disease with progressive and relapsing courses. The main clinical presentations are diffuse deep tendon hyporeflexia or areflexia and symmetric proximal-distal muscles weakness. Myasthenia gravis is also an immune mediated disease with fluctuating ocular and bulbar symptoms and sometimes weakness. Although both myasthenia gravis...

The TCP SYN ooding denial-of-service attack pointed out a weakness of then-current Internet protocols. There have since been many proposals to defend against SYN ooding, some requiring signiicant changes to TCP. Several solutions attempting to resolve the TCP weakness are now generally available. We document these existing solutions and qualitatively compare them. We reene the analysis of the r...
