Secondary hypokalemic paralysis with bulbar weakness and reversible electrophysiologic abnormalities: A case report and systematic review

Hypokalaemia with Guillain-Barré syndrome: a diagnostic and therapeutic challenge

Acute-onset quadriparesis is not only debilitating and a grave concern for the patient but also perturbs the clinician as it demands early diagnosis and prompt management to prevent catastrophic outcome due to respiratory failure. Guillain-Barré syndrome (GBS) and hypokalaemia are notorious causes of acute-onset lower motor neuron (LMN) quadriparesis and warrant a rapid evaluation to necessitate early management. However, coexistence of these two entities is extremely rare and may pose a diagnostic and therapeutic challenge and mandates exclusion of either condition to avoid a poor outcome. We hereby report a case of a young woman who presented with an acute-onset LMN quadriparesis, initially found to have significant hypokalaemia with poor response to supplementation and was further evaluated to have an axonal variant of GBS.

Sporadic adult-onset brainstem hyperkalemic periodic paralysis masquerading as recurrent transient ischemic attacks

We report a case of adult-onset, sporadic, hyperkalemic periodic paralysis with primary brainstem musculature symptoms masquerading as recurrent transient ischemic attacks. Unilateral brainstem weakness could be induced with rapid eye blinking, which was followed by lower extremity weakness and cramping. Treatment with acetazolamide and albuterol ameliorated the patient's attacks.
