[Acute epigastric pain after travel to the tropics. Emergency admission of a 28-year-old stewardess].

A 28-year-old stewardess was admitted to hospital with violent cramp-like pain in the right upper abdomen, which was accompanied by a single episode of watery pasty diarrhea. Over the next few days her symptoms persisted, she developed a high fever, and her general state of health deteriorated. Ultrasonography repeated on the fourth day then revealed a small space-consuming lesion in the right lobe of the liver. While the laboratory investigations initially remained negative, the suspected amebic abscess and colitis were subsequently also confirmed serologically.

[Acute hemolysis with subsequent life-threatening pancreatitis in hemodialysis. A complication which is not preventable with current dialysis equipment].

A retrospective study was undertaken of 14 patients (eleven men, three women; mean age 52 [33-68] years in whom haemolysis had occurred during chronic haemodialysis (n = 12) or haemofiltration (n = 2). The haemolysis was of mechanical cause in eight patients, by an osmotic mechanism in one, and of unknown cause in five. Cardinal symptoms were nausea in 14 patients, abdominal pain in nine, vomiting in eight and raised blood pressure in ten. The plasma was discoloured in all patients and there was also an increase in free haemoglobin (110-2400 mg/dl) and (or) lactate dehydrogenase (311-7403 U/l). In all of eleven patients in whom it was measured the activity of serum amylase and (or) lipase was more than doubled (to 73-2400 U/l and 473-16,740 U/l, respectively). All patients were treated symptomatically, three had a blood exchange, two others plasma separation. Eight patients recovered within a few days, but necrotizing pancreatitis developed in six, three of whom died while two had permanent sequelae. This series shows that dialysis-induced acute haemolysis can cause life-threatening pancreatitis. Narrowings within the extracorporeal circuit, not always recognized in current dialysis equipment, are the most frequent cause of the mechanical haemolysis.

[Anaesthesia in hypercalcaemic coma (author's transl)].

Hypercalcaemic coma leads to changes in myocardial efficiency and skeletal muscle tone. It is difficult to recommend a favourable anaesthetic agent for such a rare but acute and serious clinical condition. Our experiences are against administration of enflurane. It seems to be that neurolept anaesthesia is the most suitable method for those patients.

[Angiopathy in a case of primary oxalosis combined with familial spherocytosis (author's transl)].

An 18-year-old female with primary oxalosis, seen first when she was in advanced renal failure, developed a severe necrotizing angiopathy which began after a rapid decrease in renal function requiring chronic dialysis. Because of the severe angiopathy the preliminary diagnosis of an acute autoimmune vasculitis had been made. The correct diagnosis was revealed by renal biopsy and a renal transplantation performed. Soon after severe oxalosis led to failure of the renal transplant and death. The patient had also had familial spherocytosis, inherited from her father, while the oxalosis had been inherited from her mother. It is suggested that early transplantation at the onset of renal failure, as long as the blood oxalate level is still tolerably low, may give better results than have so far been reported.

[Long-time observation of a case of retroperitoneal fibrosis with Klinefelter's syndrome (author's transl)].

The etiology of retroperitoneal fibrosis still is largely unknown. Autoimmunologic mechanisms, traumata, systemic diseases, and drugs have been discussed as possible etiologic factors. The presented case was found to have a Klinefelter's syndrome besides retroperitoneal fibrosis. We do not believe that there is a relation between the two diseases. The retroperitoneal fibrosis of this case responded well to glucocorticosteroid therapy and the severly reduced renal function became normal.

[The use of photon absorptiometry in renal osteodystrophy (author's transl)].

In 58 patients with end-stage renal failure before commencement of regular hemodialyses treatment (RTD) and 58 patients under RTD bone mineral content (BMC) was determined by the use of the photon absorptiometry. Further the effect of a treatment with bitamin D3 and 5,6-trans-25-OH-vitamin D3 on BMC was studied. There existed a negative correlation between the duration of chronic renal failure or of RDT as well as of the serum parathyroid hormone level to BMC. No correlation was found between BMC and serum calcium level. During a 14 months-course treatment with vitamin D3 or 5,6-trans-25-OH-vitamin D3 BMC increased. The method of photon absorptiometry presented itself as an easy and well reproducible technique for routine examinations.

Renal disease in pregnancy.

Renal biopsy was obtained in 11 primiparous and 9 multiparous patients with severe pre-eclampsia. The large number of patients with renal disease allowed for single-case evaluation. Eclamptic convulsions and fetal deaths were observed in association with renal disease without foci of additional primary glomerular endotheliosis. The data indicate that pregnancy can exacerbate renal disease and allow for early diagnosis. Fluorescence angiography revealed changes in patients in whom the optic fundi were normal. Tissues of glomerulonephritis stained by immune fluorescence against immunoglobulins and on occasion against human fibrinogen. Primary endotheliosis and nephrosclerosis stained against fibrinogen only. There was no pattern of laboratory data to make the differential diagnosis between primary endotheliosis and various forms of renal disease. Fibrinogen breakdown products were inconsistently increased in contrast to fibrin monomer formation, which was increased regardless of the underlying morphology. It is our feeling that renal biopsy with subsequent pathologic classification is the only technique we have at present which provides relevant information on the effect of renal disease on pregnancy and vice versa.
