Eight cases are reported of extensive retroperitoneal haemorrhage in patients receiving anticoagulant therapy who subsequently died and underwent postmortem examination. No patient had an obvious source of bleeding, and in 5 cases no other cause for death was apparent. Three patients had had vascular surgical procedures: the other 5 were given anticoagulants for suspected venous thrombo-embolism. Six cases presented as unexpected circulatory collapse with rapid demise. Four patients had in addition gastro-intestinal bleeding of varying degree, with no obvious source. This acute massive type of retroperitoneal bleeding contrasts with the commoner presentations of pain, swelling, bruising and compression neuropathy: a high index of suspicion and urgent treatment are required if mortality is to be reduced.

From September 1984 to August 1991, 48 evaluable patients with resected gastric cancer and apparent disease confined to locoregional area were treated with intraoperative electron beam boost to the celiac axis and peripancreatic nodal areas (15 Gy) and external irradiation (40 to 46 Gy in 4 to 5 weeks) including the gastric bed and upper abdominal nodal draining regions. At the time of evaluation for IORT, the disease was primary in 38 cases, recurrent but resectable in four (anastomosis), and unresectable in four (nodal). Post operative complications were reversible. Acute tolerance to the complete treatment program was acceptable. Late complications included life-threatening events: Six episodes of gastro intestinal bleeding (three of them had an arteriographic documentation of arterioenteric fistula) and nine with severe enteritis (five required reoperation). Other long-term treatment related complications were six cases of vertebral collapse. The median follow-up time for the entire group is 22 months. Locoregional recurrence/persistence of disease has been identified in five patients (three with residual and/or recurrent postsurgical tumor). Systemic tumor progression has been detected in 15 patients (11 in intra-abdominal sites). Overall actuarial survival for patients with positive or negative serosal involvement was 33% versus 56%. It is concluded that the treatment program described is able to induce a high locoregional tumor control rate (100%) when used strictly in an adjuvant setting and might control long term, a small portion of patients not amenable for curative surgery (2 out of 8 patients with confirmed residual post-surgical disease). Gastrointestinal bleeding and enteritis are findings that indicate treatment intensity at the upper limits of tissue tolerance. Assessment of long term tolerance of pancreatic parenchyma and large blood vessels (tissues included in the IRORT field) are pending for longer follow-up and the appropriate selective studies.

From 1995-2002, 14 patients with predominantly prehepatic, noncirrhotic portal hypertension were evaluated. At presentation, the eight females and six males had a mean age of 9 years (range 2-18). Seven were admitted with gastrointestinal, mostly esophageal bleeding, three with splenomegaly, three with hepato-pulmonary syndrome, and one with hyperammonemia. Imaging studies showed portal vein obstruction in six patients and non-obstructed but frequently anomalous vascular patterns, including hypoplasia of the portal vein, in the remaining eight patients. At the onset, liver function was marginally abnormal in all patients, but thrombocytopenia of approximately 100 x 10(9)/L was consistently observed, probably reflecting chronic mild consumption coagulopathy and hypersplenism. The most striking and frequent histopathologic finding in 25 liver samples, was the presence of hypoplastic portal triads with collapsed portal vein radicles. In contrast, other triads showed markedly distended and misshapen portal vein radicles and likely lymphatics. These two patterns of collapse and distention presumably reflect areas of impaired versus overloaded intrahepatic portal venous flow. Some of the biopsies showed variable portal/sinusoidal fibrosis. Four patients (two with intestinal bleeding, two with hepatopulmonary syndrome) required liver transplants and are doing well. Eight patients are doing well clinically after surgical or spontaneous vascular shunting. Two patients with intestinal bleeding and hepato-pulmonary syndrome, respectively) who had congenital dyskeratosis, underwent bone marrow transplantation and died of nonhepatic-related complications. It is possible to suggest prehepatic causes of portal hypertension even in needle biopsies when collapsed portal vein radicles are present in portal triads, but more than one biopsy sample with larger bore bioptomes may be required to see the changes. Conversely, identifying these changes may suggest to the clinicians the need to work-up a patient for portal hypertension.

In acute poisoning with beta-blocking drugs and calcium-channel blockers patients may present with serious symptoms. We present a case of life-threatening sotalol and verapamil intoxication in a 29-year-old female suffering from depression. She was admitted to our hospital a few hours after she had taken 3.6 g verapamil and 4.8 g sotalol. On being found the patient was breathing and had a palpable pulse. On admission the patient experienced a cardiovascular collapse and CPR was started. Echocardiography confirmed cardiac standstill. After 4 h of normothermic CPR, extra corporeal heart lung assist (ECHLA) was established. Vasoactive drugs could be stopped after 2 days with ECHLA, and after 5 days the patient was extubated. The patient experienced several complications (intestinal bleeding, transient nerve paralysis, and renal failure due to rhabdomyolysis) but made a complete recovery and started working 6 months after the poisoning. She was no longer depressed.
