RESUMEN
The cryoprobe device is commonly used by orbital surgeons for the extraction of intraorbital lesions. Cryoprobes provide a safe mechanism to manipulate fluid-filled tumors. Such lesions can present in locations in which intraoperative neurosurgical assistance is essential. The authors describe a technique whereby removal of an orbital hemangioma was facilitated by the aid of an endoscopic, transnasal cryoprobe while standard microsurgical dissection was performed concurrently via a transconjunctival approach.

STUDY DESIGN: Case report. OBJECTIVE: To describe a rare case of congenital absence of the internal carotid artery (ICA) in the setting of acute spinal cord injury and review the existing literature. SETTING: Regional Spinal Cord Injury Center of the Delaware Valley, Philadelphia, PA, USA. CLINICAL PRESENTATION: We report on a 47-year-old male who presented as a T2 ASIA A spinal cord injury with a T2-T3 fracture dislocation injury after a 25-feet fall from a tree. Magnetic resonance angiography imaging of the neck carried out as per routine spinal trauma protocol suggested an acute traumatic injury to the carotid artery. Therefore, computed tomographic angiography imaging of the neck was performed, which revealed absence of the left ICA and a diminutive left carotid canal at the skull base, suggesting congenital absence. Follow-up magnetic resonance imaging of the brain to evaluate for acute infarct showed no diffusion restriction contributing to the evidence that this was a congenital anomaly and not traumatic occlusion of the artery. CONCLUSION: Congenital absence or hypoplasia of the ICA is a rare anomaly. It should be considered in the differential in patients who have absent or diminished carotid arteries on radiologic imaging in the setting of trauma.

In this epidemiological study, stool samples were collected from 256 study subjects selected from seven villages of Kanpur district, Uttar Pradesh, India. The average age of the study population was 21.6 years. The overall prevalence rate of hookworm infestation was found to be 34%. Men had significantly higher rate of infestation at all ages. Prevalence rates increased with ages as well. In addition, adult worms were collected from twelve subjects. All were identified as Ancylostoma duodenale.
