Retroperitoneal fibrosis is a disease which causes renal failure by obstruction of the ureters. The fibrosis may be benign or secondary to malignant disease. The clinical and radiological features of 30 cases have been reviewed. The symptoms are non-specific and diagnosis is often difficult. The most important features are back pain associated with a high ESR. Urography is diagnostic; the well known features are obvious dilatation of the pelvicalyceal system and ureter above the level of the obstruction. However, there is a spectrum of appearances corresponding to the duration of the disease and there may be only minimal dilatation of the pelvicalyceal system or no pelvicalyceal opacification at all. The progress of the disease is variable. Slow progress leads to chronic obstruction and chronic ill health. With more rapid progression, the patient may present with acute obstruction in anuria and, in such cases, urgent ureterolysis is necessary to conserve nephrons. Benign and malignant retroperitoneal fibrosis are often indistinguishable, clinically and radiologically, and laparotomy with biopsy is essential for diagnosis.

Endoluminal stent graft repair of abdominal and thoracic aortic aneurysms is being performed in increasing numbers. The long-term benefits of this technology remain to be seen. Reports have begun to appear regarding complications of stent graft application, such as renal failure, intestinal infarction, distal embolization, and rupture. Many of these complications have been associated with a fatal outcome. We describe a case of acute, retrograde, type B aortic dissection after application of an endoluminal stent graft for an asymptomatic infrarenal abdominal aortic aneurysm. An extent I thoracoabdominal aortic aneurysm subsequently developed and was successfully repaired. Aggressive evaluation of new back pain after such a procedure is warranted. Further analysis of the short-term complications and long-term outcome of this new technology is indicated before universal application can be recommended.

Blackwater fever is characterized by severe intravascular hemolysis with renal failure caused by recurrent use of quinine for prophylaxis. Once described in European patients, sporadic cases have been reported more and more often in autochthonous Africans and Asians. Newer antimalarials including aminoalchohol mefloquine, and halofantrine have also been implicated in Blackwater fever. In this report we describe two cases of blackwater fever involving patients with sickle cell anemia (HbSS). Symptoms including fever, acute hemolytic anemia, emesis, back pain, and hemoglobinuria were characteristic of blackwater fever. Both patients died. Although the underlying mechanism of blackwater fever remains unclear, a likely explanation is an immunoallergic reaction to quinine. Association with glucose-6-phosphate dehydrogenase deficiency has often been reported. Our cases suggest that blackwater fever may also be correlated with hemoglobinopathy such as HbSS.

It is now recognized that the majority of patients on epoetin therapy require intravenous (IV) iron supplementation to maximize the response to treatment. Of the IV iron preparations available, iron sucrose has proved its efficacy and safety; however, there are no guidelines or systematic studies examining the optimum safe dosage regimen for this compound. The aim of the present study was to investigate prospectively a variety of dosing regimens for IV iron sucrose in patients with renal failure to develop treatment strategies for this preparation. A total of 335 iron infusions was administered to 249 patients in this study, which was conducted in four phases. In phase I, 89 patients were administered a dose of 200 mg as an IV infusion over 2 hours. No adverse events were seen. A 500-mg dose by 2-hour infusion was then assessed, but was abandoned after 8 of 22 patients developed reactions characterized by dizziness, hypotension, and nausea. The dose was then reduced to 300 mg by 2-hour infusion for the next 189 patients, and again, no adverse reactions were witnessed. Finally, a 400-mg dose by 2-hour infusion was examined in 35 patients, but 2 patients experienced such symptoms as hypotension, nausea, and lower back pain. Both the 200- and 300-mg doses of IV iron sucrose administered over 2 hours appear to be safe. The incidence of adverse events with the 400- and 500-mg doses administered as a 2-hour infusion seems too high to recommend their routine use, although it may be possible to administer these doses over a longer period.

This report describes a 15-year-old white boy who presented with fever, back pain, a disseminated exanthematous rash, renal failure, and hepatopathy 3 weeks after the initiation of oral minocycline therapy for facial acne. Marked peripheral and urine eosinophilia were noted. A bone marrow aspiration showed more than 50% eosinophils without any evidence of malignancy, and a simultaneous kidney biopsy showed acute interstitial nephritis (AIN). The patient's symptoms and laboratory findings improved after high-dose steroid therapy was initiated, worsened when it was withheld, and improved again after it was reinitiated in view of the biopsy findings. The patient recovered completely, and steroids were tapered to discontinuation over 3 months. Over a year later, the patient's peripheral blood mononuclear cells (PBMCs) were cultured for 2 weeks in the presence or absence of minocycline ex vivo, and minocycline was found to induce the emergence of CD4(+) cells after 1 week in culture. In conclusion, this article shows for the first time several new aspects of minocycline-induced morbidity: renal and hepatic failure can occur together, and AIN and elevated blood eosinophil counts can be accompanied by marked bone marrow eosinophilia, suggesting a systemic allergic response as the underlying pathomechanism. Furthermore, the initial phase of such a response appears to involve CD4(+) T cells detectable ex vivo. Lastly, high-dose treatment with corticosteroids appears to be beneficial in this setting.

Retroperitoneal fibrosis (Ormond's disease) is rare chronic inflammatory process, that can occur at any age. It is characterised by development of periaortic fibrous mass leading to progressive obstruction of vessels around the abdominal aorta and ureters. In the one third of cases we can find the causes of disease. There are ergotamine abuse, radiation, retroperitoneal surgery or hemorrhage, urine extravasation and response to different cancers. The other cases are idiopathic disease. We report a case of prostate cancer with unique course. The first manifestations of disease were diffuse peritoneal fibrosis and ureteral obstruction leading to bilateral hydronephrosis. Clinical course and histopathology showed idiopathic Ormond's fibrosis. Patient received oral immunosuppressive treatment (prednisolone 1 mg/kg/day + azathioprine 1 mg/kg/day), followed by intravenous methylprednisolone puls (2 g). Treatment also consisted of DJ-stent placement on the left side. On the right side we were unable to overcome the obstruction of ureter. Because of persistent renal failure, thrombocytopenia, DIC and progressive lower back pain we did control MR and CT scan. The CT scans showed multiple osteolytic bone metastases in vertebral column (the sizes of them were between a few millimetres and 1.5 centimetre). Patient died due to renal failure and haemorrhagic diathesis in the course of disseminated cancer of unknown origin. The postmortem examination revealed diffuse peritoneal infiltration surrounding the ureters, intramural ventricular metastases, pulmonary metastases and vertebral metastases. The prostate was only slightly enlarged. Histological and immunohistochemical examinations of prostate showed primary low-differentiated prostate carcinoma (CK/+/, PAP/+/, PSA/+/). Peritoneal, ventricular and bone infiltrations also were metastases from low-differentiated carcinoma of prostate origin (CK/+/, PAP/+/, PSA/-/).

A 65 years man presented with fever, drenching sweats, progressive dyspnoea, backache and weight loss. On examination, he had wide pulse pressure, clubbing, retinal hemorrhages, aortic and mitral regurgitation, hepatosplenomegaly, lower spinal tenderness and bilateral basal crepitations. Transthoracic 2D-echocardiography showed a large vegetation on the aortic valve. Antibody titers for brucella were positive. X-ray spine was suggestive of brucella spondylitis. Early surgical intervention was planned and the patient was given combination antibiotic therapy. The course was complicated by renal failure and the patient succumbed while being taken up for surgery.

A 93-year-old patient with a cardiac pacemaker and biochemical renal failure presented with back pain suspicious for dissection. We performed gadolinium-enhanced thoracoabdominal multidetector CT angiography using eight-channel multidetector CT. Uniform aortic enhancement of 140 HU was sufficient to exclude aortic dissection and defined an unruptured infrarenal abdominal aortic aneurysm.

Backache, a common symptom, is rarely caused by infection of the lumbar discs. The authors present the case of a 60-year-old man with a Staphylococcus aureus septicemia and associated lumbar discitis in whom a pauci immune crescentic glomerulonephritis and renal failure developed. Treatment with antibiotics and not immunosuppressive agents resulted in improved renal function with a discharge creatinine level of 1.87 mg/dL (165 micromol/L). This case highlights an association of pauci-immune crescentic glomerulonephritis with discitis that responded to antibiotic therapy alone.

The prevelance of ankylosing spondylitis or sacroiliitis in Behcet's disease has been the subject of debate for some time. Two cases with atypical presentation and course are discussed. The first patient was a young woman with Behcet's disease whose primary complaint was neck pain. X-ray examination showed severe cervical involvement, characteristic of the type seen in women with ankylosing spondylitis. She subsequently developed anterior uveitis. The second patient was a man suffering from back pain and limited movement of his neck and back. When he was referred to our outpatient clinic, his severe anemia became the subject of the whole investigation. He was diagnosed with Behcet's disease with ankylosing spondylitis accompanied with amyloidosis and an end-stage renal failure.
