An uncommon presentation of orbital apex syndrome.

BACKGROUND: Bilateral total ophthalmoplegia secondary to a malignancy or infection of the cavernous sinus and orbital apex is an unusual presentation. Bilateral ophthalmoplegia as the initial sign of this type of rhinocerebral pathology is also uncommon. CASE REPORT: A 34-year old Haitian woman presented with bilateral vision loss, ptosis, total ophthalmoplegia, and ocular pain. A physical and neurologic examination, laboratory analysis, chest x-rays, and neurologic imaging studies were requested. Cranial and facial computed tomography (CT) scans showed swelling of the soft tissues proximal to the sphenoid extending into the dorsal sella and prepontine cistern, obliteration of the nasopharyngeal reflection, opacification of the ethmoid and sphenoid sinus, bony destruction of the mid-skull base, and bilateral lymphadenopathy of the neck. Magnetic resonance imaging (MRI) showed the presence of a soft tissue mass causing destruction of the skull base. Involvement of the clivus, cavernous sinuses, and sella with nasopharynx extension was observed. Hypodense centers within nasopharyngeal tissues suggested the presence of necrosis. Differential diagnosis included nasopaharyngeal carcinoma, lymphoma, or an infectious process. The patient did not consent to a biopsy and refused treatment. CONCLUSION: This presentation is a medical emergency. A combination of surgical, medical, or radiological intervention may be required to manage rhino-cerebral diseases responsible for orbital apex syndrome. Despite advances in neurologic imaging, histologic examination of tissue obtained from a biopsy may ultimately be necessary to obtain a precise diagnosis.     

Healthcare utilization following spinal cord injury: Objective findings from a regional hospital registry

Objective: The purpose was to describe the prevalence and characteristics of healthcare utilization among individuals with spinal cord injury (SCI) from a Level I trauma center.

Design: Retrospective data analysis utilizing a local acute trauma registry for initial hospitalization and merged with the Dallas-Fort Worth Hospital Council registry to obtain subsequent health care utilization in the first post-injury year.

Setting: Dallas, TX, USA.

Participants: Six hundred and sixty four patients were admitted with an acute traumatic SCI from January 2003 through June 2014 to a Level I trauma center. Fifty five patients that expired during initial hospitalization and 18 patients with unspecified SCI (defined by ICD-9 with no etiology or level of injury specified) were not included in the analysis, leaving a final sample of 591.

Outcome Measures: Data included demographic and clinical characteristics, charges, and healthcare utilization.

Results: Mean age was 46.1?years (±18.9?years), the majority of patients were male (74%), and Caucasian (58%). Of the 591 patients, 345 (58%) had additional inpatient or emergency healthcare utilization accounting for 769 additional visits (median of 3 visits per person). Of the 769 encounters, 534 (69%) were inpatient and 235 (31%) were emergency visits not resulting in an admission. The most prevalent ICD-9 codes listed were pressure ulcer, neurogenic bowel, neurogenic bladder, urinary tract infection, fluid electrolyte imbalance, hypertension, and tobacco use.

Conclusion: Individuals with SCI experience high levels of healthcare utilization which are costly and may be preventable. Increasing our understanding of the prevalence and causes for healthcare utilization after acute SCI is important to target preventive strategies.
