RESUMO
BACKGROUND: The conventional treatment for idiopathic intracranial hypertension involves weight loss, steroids, diuretics, and/or serial lumbar punctures; however, if the symptoms persist or worsen, surgical intervention is recommended. Surgical options include cerebrospinal fluid diversion procedures, such as ventriculoperitoneal and lumboperitoneal shunts, and optic nerve decompression with nerve sheath fenestration. The latter can be carried out using an endoscopic approach, but the outcomes of this technique have not been firmly established. METHODS: This systematic review examined the outcomes of performing endoscopic optic nerve decompression (EOND) in patients with idiopathic intracranial hypertension (IIH). Six studies were included for a total of 34 patients. RESULTS: The patients presented with visual field disturbances (32 of 32 [100%]), visual acuity disruptions (33 of 34 [97.1%]), papilledema (26 of 34 [76.5%]), and persistent headache (30 of 33 [90.1%]). The mean duration of symptoms ranged from 7 to 32 months. Overall, the patients showed post-EOND improvement in signs and symptoms associated with IIH, specifically visual field deficits (93.8%), visual acuity (85.3%), papilledema (81.4%), and headaches (81.8%). Interestingly, 11 cases showed postoperative improvement in their symptoms with bony decompression of the optic canal alone, without nerve sheath fenestration. There were no major adverse events or complications reported with this approach. CONCLUSION: EOND appears to be a promising and safe surgical alternative for patients with IIH who fail to respond to medical treatment. Further studies are needed before we can attest to the clinical validity of this procedure.

Renal stones (nephrolithiasis) are a relatively common problem and a frequent Emergency Department (ED) diagnosis in patients who present with acute flank/abdominal pain. The goal of this topic review is to provide physicians with an evidence-based diagnostic approach for the evaluation and management of patients with nephrolithiasis. Unenhanced helical CT scan of the abdomen and pelvis should be performed on all patients with their first episode of acute flank pain and suspected renal colic. It is considered the optimal diagnostic test to confirm a urinary stone in a patient with flank pain. Pain management can be achieved by using NSAIDs, opioids or a combination of both. Several factors will help you determine if emergent urology evaluation is warranted; size and location of renal calculi, persistence of colic pain, impaired renal function and signs of infection.
