Minimally Invasive Subtemporal Intradural Approach for Penetrating Orbitocranial Injury by Wooden Foreign Body Into the Lateral Wall of the Cavernous Sinus.

Non-missile transorbital penetrating head injuries are relatively rare, though potentially fatal injuries. Trajectory for intracranial entrance is typically via the orbital roof, the superior orbital fissure (SOF), or the optic canal. Non-metallic intracranial penetrating injuries are even scarcer and may pose unusual diagnostic and surgical challenges. Here we present and discuss a unique case of a penetrating injury by a wooden foreign body (FB) which entered and expanded the inter-dural space of the lateral cavernous sinus (CS) sinus wall without intracavernous or intradural involvement. The patient was a 71 year-old male who fell face-down and sustained a penetrating transorbital injury by a dry twig fragment, which passed through the SOF and into the interdural space of lateral wall of the ipsilateral CS. The patient was fully conscious (GCS15) at presentation but had severe ocular injury (complete ophthalmoplegia and blindness of the injured eye). The wooden FB was successfully removed via a minimally invasive subtemporal intradural approach with no apparent immediate or long-term complications. We emphasize the unusual diagnostic and surgical challenges related to this kind of rare injuries as reflected by the decision-making considerations taken in the presented case.

Varicella pneumonia in southern Israel: clinical characteristics, diagnosis and therapeutic considerations.

BACKGROUND: The most common and most serious complication of varicella (chickenpox) in adults is pneumonia, which can lead to severe respiratory failure. Varicella pneumonia is associated with considerable morbidity and even death. OBJECTIVES: To summarize our experience with varicella pneumonia in terms of clinical, laboratory and radiological characteristics as well as risk factors, management and outcome. METHODS: We conducted a retrospective cohort survey in our facility from 1995 to 2008. RESULTS: Our cohort comprised 21 patients with varicella pneumonia, of whom 19 (90%) were men; their mean age was 35 +/- 10.5 years. Nineteen patients (90%) were Bedouins and 18 (86%) were smokers. Eleven (52%) were admitted to the Medical Intensive Care Unit; 3 of them required mechanical ventilation and the remaining 10 (48%) were admitted to the general medical ward. Median length of stay was 6 +/- 7.7 days. Hypoxemia and elevated lactate dehydrogenase on admission were associated with respiratory failure. Radiological manifestations were variable and nine patients exhibited characteristic findings. All but one patient were treated with acyclovir. All patients fully recovered. CONCLUSIONS: In southern Israel varicella pneumonia is primarily a disease ofyoung male Bedouins who are smokers. Severity ranges from mild disease to severe, resulting at times in respiratory failure requiring mechanical ventilation. Prognosis is favorable with complete recovery.
