Index Digit Necrosis as a Complication of Radial Artery Cannulation.

Arterial access is therapeutically and diagnostically useful. Its clinical utility is vast, and associated complications are infrequent. However, some unfortunate patients progress to disastrous outcomes. Luckily, ischemic hand complications are rare. Hand ischemia threatens independence and quality of life, thus warranting vigilance. We present a case of index digit necrosis as a complication of arterial cannulation in a 30-year-old patient with end-stage renal disease admitted to an intensive care unit.

Microcephalic Osteodysplastic Primordial Dwarfism Type II With Associated Glucose-6-Phosphate Dehydrogenase Deficiency in a Saudi Girl.

Microcephalic primordial dwarfism is a group of disorders that result in growth restriction and multiple morbidities. The condition is subdivided into three categories, with microcephalic osteodysplastic primordial dwarfism type II (MOPDII) being the most prevalent. Globally, only a few cases have been reported, with only available information about these disorders described in the literature. In this case report, we present the clinical findings seen in an infant with MOPDII in Saudi Arabia with associated glucose-6-phosphate dehydrogenase deficiency hemolytic anemia.

Colloid Cyst: A Potentially Life-Threatening Etiology of Severe Headache in a Patient With Migraine.

Headache is a common cause of emergency department (ED) visits. Migraine is a prevalent neurological disorder that is encountered by emergency physicians in day-to-day practice. However, patients with a known history of migraines should be carefully evaluated when presenting with headaches and serious pathologies of headache should be ruled out. We report the case of a 43-year-old woman, with a known history of classic migraine, who presented to the ED with a severe headache. She described the headache as persistent generalized pain. The headache was worse on awakening and bending. The headache did not improve with the use of oral sumatriptan. She reported that the current episode of headache is more severe than her usual migraine headaches. The patient underwent a cranial CT scan which demonstrated a homogenously hyperdense well-defined round lesion located in the midline at the approximate location of the foramen of Monro with prominent lateral ventricles, conferring the diagnosis of the colloid cyst. The patient underwent a right craniotomy with resection of the cyst using the transcallosal approach. Recognition of this important diagnosis is crucial to prevent serious neurological complications by having timely management.
