Fungal Infection in an Exenterated Orbit.

A 48-year-old man presented with an Aspergillus fumigatus complex infection of an exenterated orbit. The OS had been exenterated 7 months ago, together with total parotidectomy and neck dissection followed by irradiation due to a massive squamous cell carcinoma with orbital invasion and lymphatic metastasis. The patient was under permanent immunosuppression with oral prednisone and tacrolimus due to a kidney transplantation 5 years ago. The infected skin of the exenterated orbit was cleared using forceps. MRI ruled out any bone infiltration. After systemic treatment with oral voriconazole and topical therapy with bifonazole ointment for 6 weeks, the patient recovered completely.

Optic Nerve Sheath Diameter for Assessing Prognosis after Out-of-Hospital Cardiac Arrest.

PURPOSE: Evaluate optic nerve sheath and pial diameters (ONSD, ONPD) via sonography and computed tomography (CT) after out-of-hospital cardiac arrest (CA) and to compare their prognostic significance with other imaging and laboratory biomarkers. MATERIALS AND METHODS: A prospective observational study enrolling patients after successful resuscitation between December 2017 and August 2021. ONSD and ONPD were measured with sonography. Additionally, ONSD, and also grey-to-white ratio at basal ganglia (GWRBG) and cerebrum (GWRCBR), were assessed using CT. Lactate and neuron specific enolase (NSE) blood levels were measured. RESULTS: Sonographically measured ONSD and ONPD yielded no significant difference between survival and non-survival (p values ≥0.4). Meanwhile, CT assessed ONSD, GWRBG, GWRCBR, and NSE levels significantly differed regarding both, survival (p values ≤0.005) and neurological outcome groups (p values ≤0.04). For survival prognosis, GWRBG, GWRCBR, and NSE levels appeared as excellent predictors; in predicting a good neurological outcome, NSE had the highest accuracy. CONCLUSIONS: CT diagnostics, in particular GWRBG and GWRCBR, as well as NSE as laboratory biomarker, appear as excellent outcome predictors. Meanwhile, our data lead us to recommend caution in utilizing sonography assessed ONSD and ONPD for prognostic decision-making post-CA.
