Inter-hospital extracorporeal life support.

A 60-year-old man with history of hypertension and unspecified left ventricular dysfunction had chest pain at home at 9 am. At 1 pm he was transported to a peripheal hospital and treated for acute myocardial infarction. At 4.30 pm, despite pharmacological and intra aortic balloon pump support , the extreme hemodynamic instability and the echocardiographic signs forced the doctors in charge to contact the "extracorporeal membrane oxygenation team" of our Intensive Care Unit. The team, that in our hospital is composed of an intensivist, a cardiac surgeon, a perfusionist and a nurse, reached the hospital at 5.15 pm and performed a percutaneous cannulation of right femoral artery and left femoral vein connecting the patient to the extracorporeal membrane oxygenation circuit. At 6.30 pm the patient on extracorporeal membrane oxygenation was transferred by ambulance to the Cardiac Surgery Intensive Care Unit of San Gerardo Hospital in Monza. On day 20 he was transferred back to the original hospital without neurological deficits, with normal renal function and normal blood gas analysis.

Transsphenoidal meningoencephalocele.

BACKGROUND: Encephaloceles are rare cranio-facial developmental anomalies. CASE REPORT: In this paper, we discuss the case of an 8-month-old girl affected by a transsphenoidal meningoencephalocele and try to give landmarks of the state of art in the surgical treatment of this rare pathology.

Open-door laminoplasty for cervical stenotic myelopathy: surgical technique and neurophysiological monitoring.

OBJECT: A modified technique of open-door laminoplasty for cervical stenotic myelopathy (CSM) is described, and the role of evoked potential monitoring in selecting patients for surgery and evaluating results is discussed. METHODS: Between October 1992 and October 1996, 33 patients with CSM underwent open-door laminoplasty. After surgery, in 27 patients (81.8%) different levels of clinical improvement were demonstrated, and in five of them (15%) full recovery was observed. The Japanese Orthopaedic Association score increased from 5 to 12 (mean 9.8) preoperatively to 8 to 14 (mean 11.6) postoperatively. At 1-year follow up, the N13 cervical response was restored in nine (75%) of 12 patients with isolated presurgical abnormality and in 57.1% of those with combined abnormalities of both N13 and P14 response. Although significant clinical improvement was observed in 82% of the cases, in 24 of 33 patients motor evoked potential abnormalities persisted at least at one explored level. CONCLUSIONS: Of several laminoplasty techniques, the one described here offers some advantages: preservation of biomechanical function of posterior muscular-ligamentous complex, prevention of laminar collapse, smaller degrees in reduction of range of cervical motion, stabilization of the spine with no postoperative malalignment, and maintenance of decompressive effect that avoids recurrent stenosis. Neurophysiological studies sometimes clarified neurological disorders that were only suspected on the basis of history and/or clinical examination, leading to early diagnosis.

The preparation of a series of aroylhydrazones of halogenobenzaldehydes (I) - (XI) is described together with that of the corresponding reduction products (XII) - (XXV) and of 2,5-diaryl-1,3,4-oxadiazoles with halogen substitution (XXVI) - (XLIII). The results of pharmacological and microbiological examination of the compounds is reported.
