[Thyrotoxic hypokalemic periodic paralysis. A case report]. / Parálisis periódica hipopotasémica tirotóxica: a propósito de un caso.

Thyrotoxic hypokalemic periodic paralysis is an uncommon complication of thyrotoxicosis, characterized by attacks of generalized muscular weakness associated with hypokalemia in patients with hyperthyroidism, most frequently with Graves-Basedow disease. Treatment with antithyroid drugs and potassium supplements reversed the symptoms and the episodes of acute muscular weakness did not reappear.

[Palpebral ptosis, a rare ocular manifestation of Crohn's disease]. / Ptosis palpebral: manifestación ocular inusual de la enfermedad de Crohn.

CLINICAL CASE: An 18 year-old-woman presented with abdominal pain, diarrhea, and ptosis in her left eye. Nuclear magnetic resonance imaging (NMRI) and the study of cerebrospinal fluid detected no abnormalities. Colonoscopy revealed a Crohn's disease (CD) confirmed by histological examination of biopsies. Ocular symptoms improved after appropriate treatment of the underlying CD. DISCUSSION: Inflammatory bowel disease (IBD) is associated with a wide variety of extra-intestinal manifestations, in fact it may be considered a systemic disorder with predominantly gastrointestinal tract manifestations. Extra-intestinal manifestations of inflammatory bowel disease (IBD) occur in one third of patients. Ocular complications are infrequent, occurring in less than 10% of cases, but can be associated with significant morbidity, including blindness. Ocular symptoms may precede a diagnosis of IBD. We report the first case of palpebral ptosis associated with Crohn's disease.
