In a case of CO poisoning CT scanning revealed bilateral low density areas in the globi pallidi, associated with diffuse hypodensity of the white matter of the cerebral hemispheres. Serial scanning threw some light on the possible mechanism involved and appears to support the hypothesis of necrotic damage of vascular origin following brain edema. An attempt is made to correlate the pattern of CT abnormalities with clinical evolution.

6 cases of brainstem hematoma were studied utilizing CT scan and brainstem auditory evoked potential (BAEP) recordings. CT scan did not contribute to an early discrimination between primary and secondary hematomas. Size of the hematoma and the presence of blood in the CSF did not represent evident signs in differentiating benign from unfavourable brainstem hematomas or hemorrhages. BAEP recordings showed the presence of electrophysiological anomalies at the level of the lesion, demonstrating that bleeding as well as tumor in the brainstem can provoke a focal damage.
Computerized tomography was performed in 31 patients presenting clinical signs of cerebellar degeneration. CT abnormalities consistent with cerebellar atrophy were found in all cases but one. Specific patterns of abnormality were found in olivo-ponto-cerebellar degeneration and in alcoholic atrophy. The CT findings in spino-cerebellar degeneration were varied, ranging from severe diffuse cerebellar atrophy to normality, possibly according to age and duration of symptoms.

A case of primary duodenal adenocarcinoma is described. A discussion is made about the rarity of this tumor that, as it is frequency misdiagnosed in cases of malignant neoplasms of the papilla of Vater and of terminal part of the common biliary duct, may be greater than all previously thought. Tumors of the third part of duodenum are even more uncommon. Whipple resection seem the best cure of this tumors, as results from long term survival.

BACKGROUND: Body temperature tends to increase during conventional haemodialysis; this might interfere with normal cardiovascular response to dialytic ultrafiltration, thus facilitating the occurrence of symptomatic hypotension. Putative factors responsible for changes in thermal balance during haemodialysis include heat load from the dialysis bath, reduction in convective heat loss secondary to skin vessel vasoconstriction, heat overproduction due to central stimulation by bioincompatibility reactions to the filter membranes. The aim of the present study was twofold: to define thermal energy balance (ET) during dialysis and to investigate the effect of membrane bioincompatibility on energy balance METHODS: We measured ET in 12 patients (9M, 3F) during two identical dialysis sessions, differing only in the membrane composition of the filters used: cuprophane 1.3- 1.6 mq and LF polysulphone 1.3- 1.6 mq. Thermal energy balance studies were performed by the Blood Temperature Monitor (Fresenius Medical Care) under conditions in which the core temperature of the patients was maintained unchanged from the start to the end of the dialysis procedure. RESULTS: Arterial blood temperatures were constant, while dialysate and venous blood temperatures progressively decreased (from 36.9 to 35.4 C and from 36.5 to 35.1 C for cuprophane; from 36.9 to 35.2 and from 36.9 to 35.1 for polysulphone membrane). Mean thermal energy transfer was negative (removal of energy from the patients to the extracorporeal circuit) with both filters, equal to 146 KJ with cuprophane and to 163 KJ with polysulphone. When a stepwise multiregression analysis was applied, hourly energy transfer (ET) was significantly and independently correlated with both ultrafiltration rate (UF=% b.w.) and heart rate changes (HR) according to the equation: ET= -92.03+41.29 UF+1.04 HR (p<0.0003). Conclusions. In this study we present experimental evidence that increased body temperature during dialysis is not caused by heat load from the dialysis bath, nor by heat over production secondary to bioincompatibility reactions. Consequently, haemodynamic responses to dialytic ultrafiltration may be regarded as the main regulatory factor of thermal balance.
