beta 2-M amyloidosis mainly concerns dialysis patients and typically presents with osteoarticular symptoms. In order to precise the incidence and gravity of visceral involvement, subcutaneous abdominal fat aspirates, skin and rectal biopsies, as well as echocardiograms were performed in 26 patients with severe beta 2-M amyloidosis. Visceral amyloidosis was confirmed in 58% and the numbers were even higher when including heart abnormalities suggestive of amyloidosis (81%). Clinical manifestations of visceral involvement were usually not severe and include odynophagia, gastrointestinal haemorrhage, intestinal obstruction, kidney stones, myocardial dysfunction and subcutaneous tumours. The removal and synthesis rates of beta 2-M were assessed during dialysis. Serum 131I-beta 2-M levels decreased by 5-10% with cuprophane and by 40-45% with polysulfone and polyacrylonitrile membranes. These reduction rates were higher than those found with unlabelled beta 2-M suggesting an increased synthesis or release during dialysis. The protein constituents of amyloid deposits were studied. Two different preparative methods to extract the proteins from amyloid deposits were used. TCA precipitation showed the presence of several proteins which were not observed with PBS homogenizing and resuspending in guanidine. The protein constituents of amyloid fibrils were studied by both, two dimensional gel electrophoresis (2D-gel) as well as protein sequencing after gel filtration. Similarly, the technical approach used for protein analysis greatly influenced the results. It was observed that 2D-gel displayed the presence of proteins which were missed by the gel filtration technique. Some of the proteins contained in amyloid deposits in addition to beta 2-M, were identified as globin chains, kappa and lambda light chains of immunoglobulins, and alpha 2 macroglobulin. A putative participation of these other protein constituents on the pathogenesis of beta 2-microglobulin amyloidosis is discussed.

During the period from 1974 to June 2000 we used the straight ileo-anal Soave pull-through to treat 42 patients (24 affected by total colonic aganglionosis [TCA], 10 with ulcerative colitis and 8 with familial polyposis). The aim of this paper is to show that this operation, associated with total colectomy, is highly recommended, causing a lower number of complications when compared to the various "reservoir" techniques. The mean age of the 24 patients with TCA at the time of the pull-through was 2.8 years; in the ulcerative colitis group, it was 14.3 years and in the familial polyposis group 27.2 years. We always used an ileo-anal deferred anastomosis and never performed temporary loop-diverting ileostomy at the time of the pull-through. In the TCA patients we had no immediate or long-term serious post-operative complications: ileal adaptation, after a frequency of 10 - 12 liquid stools a day, showed a gradual, constant and in some cases amazing improvement in all children. Two years after surgery, the mean stool frequency was 3.6 per 24 hours with no significant differences between the 3 main groups; only 4 children still presented with occasional soiling. After pull-through, all children showed normal growth curves in the long term. There was no malabsorption, no serious electrolyte imbalance, no perianal excoriation, no strictures or intestinal obstruction; their quality of life was considered more than satisfactory by the children's families. We have no direct experience with the various ileal "reservoir" techniques for ulcerative colitis and ileal polyposis nor with colon-sparing operations for TCA; as reported in the literature, all these surgical procedures seem to have a higher number of complications such as pelvic sepsis, pouchitis, enterocolitis, etc. compared with our series; we therefore confirm that total colectomy with the straight ileo-anal Soave pull-through is our treatment of choice, as it is simpler to perform and has fewer short- and long-term complications.

Althoughtricyclic antidepressants(TCAs) are frequently prescribed to patients with depression, these drugs can also be misused. A 21-year-old comatose patient was referred to our hospital presenting with ventricular tachycardia. Despite initial treatment including intravascular lipid emulsion, ventricular fibrillation occurred soon after arrival. Venoarterial extracorporeal membrane oxygenation and therapeutic hypothermia were administered. Refractory arrhythmia disappeared on the next day. A high concentration of amitriptyline was identified in his blood samples on arrival. Mechanical bowel obstruction followed after abdominal compartment syndrome caused by anticholinergic effects, and refractory seizure occurred due to TCA intoxication. Although seizure was brought under control with anticonvulsant agents, his Glasgow Coma Scale did not recover to the full score. MRI presented irreversible damage to the bilateral frontal lobe and insula. Amitriptyline has the potential to cause unusual serious complications, such as abdominal compartment syndrome, irreversible central nervous system disability and lethal arrhythmia.
