One hundred and thirty-seven patients with murine typhus were reviewed. A history of direct contact with rats was rare, and none gave a history of flea bite. No seasonal trend was observed. Clinical presentations included fever (100%), hepatomegaly (24%), rash (20%) and non-specific signs. Complications were uncommon but included jaundice, pneumonia, renal insufficiency and meningitis. Only two patients died. A single 200 mg dose of doxycycline significantly shortened the duration of fever: 79% were afebrile in 48 h, compared to 15% of the untreated group.

Observation on 32,448 salmonellosis patients was carried out. In 653 cases (2.01%) the complicated course of the disease was observed. It was caused by generalized disturbances in blood circulation, or shock, in 0.09% of cases, or by regional disturbances in blood circulation (myocardial infarction in 0.4%, acute disturbances in cerebral circulation in 0.4%, thrombosis of mesenterial vessels in 0.1% of cases). In addition, infectious complications developed in the form of pneumonia (0.5%) and acute renal insufficiency (0.6% of cases). Acute adrenal insufficiency, observed in the past, did not practically occur during the recent 20 years, having lost its importance due to the use of adequate therapy with polyionic crystalloid solutions.

Imipenem was registered for clinical use in Germany in 1985. It is recommended for initial treatment in either severe nosocomial infections or infections in ICU or immunocompromised patients. In this study, we evaluated 1,215 patients who were prescribed imipenem at our Zentrum der Inneren Medizin-a major tertiary care university hospital-over a 6 year period. 650 of 1,215 patients (53.5%) had rapidly fatal disease; and the main indication for imipenem was pneumonia and fever of unknown origin. 56.2% received 500 mg imipenem t.i.d., 40.4% 500 mg b.i.d., 0.9% 1000 mg b.i.d.; and 2.5% 1000 mg t.i.d. Average duration of treatment was 11 days. Lower dose (500 mg b.i.d.) was used in patients with renal insufficiency; highest dose was used in severe infections or infections caused by moderately sensitive organisms. Imipenem was used as a single initial antibacterial agent in the majority of the patients. Success was seen in 80% of the episodes, irrespective of the dosage used; 89% at 500 mg b.i.d., 74% at 500 mg t.i.d., 77% at 1,000 mg b.i.d.; and 69% at 1,000 mg t.i.d. We observed the highest favourable response (91.5%) in the episodes treated initially with imipenem monotherapy. Overall, imipenem was well tolerated. The majority of the patients with untoward effects was on multiple-drug regimens. The most frequent untoward event observed involved the gastrointestinal tract.

Community-acquired pneumonia (CAP) is likely to be severe in the very elderly, and clinically significant in those with hepatic/ renal insufficiency, cardiopulmonary disease, or, impaired host defenses. Pathogens in mild, moderately severe, and severe CAP are the same. These pathogens determine prognosis, complications, and duration of therapy. Empiric antimicrobial therapy should be based on likely pathogens, not severity of illness which affects the potency but not spectrum of antibiotic selected.

Following the detection of cytomegalovirus antigen in mesangial cells of some patients with IgA nephropathy, an important role of human cytomegalovirus in the pathogenesis of IgA nephropathy has been discussed. We studied a case of IgA nephropathy with rapid deterioration of renal function associated with cytomegalovirus infection. Following an infection of the upper respiratory tract, a 57-year-old woman developed with hematuria and acute renal failure. The histological diagnosis of IgA nephropathy was established and renal function transiently improved during immunosuppressive therapy. However, the ensuing clinical course was complicated by severe bleeding from intestinal ulcera, thrombocytopenia, pneumonia and relapse of renal failure. The histological investigation of colonic mucosa showed characteristic "owl's eye" cells leading to the diagnosis of cytomegalovirus disease as the cause of intestinal bleeding. Immunosuppression was stopped and treatment with ganciclovir started. Pneumonia as well as intestinal bleeding disappeared and, of particular note, renal function improved considerably. Following discontinuation of antiviral therapy CMV-disease reoccurred and renal function deteriorated again. The patient was restarted on ganciclovir therapy and, again, serum creatinine fell quickly. This impressive and reproducible clinical improvement of renal insufficiency under antiviral therapy with ganciclovir provides some evidence for an important role of cytomegalovirus in the pathogenesis of this case of IgA nephropathy.

A patient with the acquired immunodeficiency syndrome (AIDS) and sickle cell anemia presented to the University of Wisconsin Hospital on two separate occasions with pneumocystis carinii pneumonia (PCP). On both occasions he was treated with high-dose intravenous trimethoprim/sulfamethoxazole (TMP/SMX). Several days into each treatment course he developed hyperkalemia and systemic acidosis consistent with hyperkalemic renal tubular acidosis (RTA). The abnormalities resolved in the first instance with the addition of amphotericin B while continuing TMP/SMX, and in the second upon discontinuation of the TMP/SMX. While an increasing number of cases with TMP/SMX-induced hyperkalemia have been reported, hyperkalemic RTA is an uncommon complication of TMP/SMX therapy, occurring in patients with predisposing factors for acidosis such as aldosterone defects, medullary dysfunction and renal insufficiency.

Early complications after partial pancreatic resections and benign pancreatic tumours were analysed. 276 patients with pancreatic tumours were treated in the years 1979-1997. In 77 cases radical operation was performed. 65 patients underwent Whipple and 12--Traverso-Longmire pancreatoduodenectomy. Malignant tumour was found in 55 cases and 22 were benign. In 4 patients tumour's resection along with invaded portal vessels and portal confluence reconstruction was performed. These were the first cases with vessels resection operated in Poland. There were 2 post-operative deaths observed in that group. Complications in our material were as follows: pancreatico-jejunal anastomosis fistulae, haemorrhage from ulcers in gastro-jejunal anastomosis, diffuse peritonitis, haemorrhage from pancreatic stump vessels, ileus, acute renal insufficiency, pneumonia and myocardial infarct. Mortality in whole group was 11%. In the last 5 years due to our growing experience and some technical modifications mortality fell to 4.4%.

We describe two patients with sarcoidosis with lesions of granulomatous interstitial nephritis (GIN) and postinfectious glomerulonephritis (GN). Both patients presented with heavy proteinuria, hematuria, and renal failure. Renal histology in both showed GIN and glomerular changes of proliferative GN with hump-like subepithelial deposits by electron microscopy of postinfectious GN. Antecedent history of pneumonia was present in one, and ASO titer was elevated in the other. The proteinuria and azotemia improved in both with steroid therapy. Reports of "postinfectious" or diffuse proliferative GN in patients with sarcoidosis are rare. The authors are unaware of reports of concomitant sarcoid GIN and postinfectious GN. Although acute renal insufficiency or failure can occur with GIN or other more common renal lesions primary glomerular disease should be considered in patients with sarcoidosis who present with renal dysfunction. This is a US government work. There are no restrictions on its use.

Chronic inorganic arsenic toxicity was induced in goats by oral administration of one-fifth of the acute lethal dose 50 (ALD(50)) of sodium arsenite (25mgkg(-1) body weight) packed in gelatin capsules and given daily for 12 weeks. Clinical signs of toxicity developed from 3 week post-exposure, consisting of gastrointestinal disturbances and renal insufficiency with 100% mortality in all animals. There were significant (p<0.01) decreases in total serum protein and the albumin: globulin ratio, and increases in blood glucose and various enzymatic activities of treated animals. Toxicity also induced severe pathomorphological changes, indicative of haemorrhagic and degenerative and/or necrotic lesions in most organs. In addition, proliferative pneumonia in lungs, hyperplastic goitre in thyroid and chronic proliferative lesions in skin were observed. Liver contained the largest residues of arsenic, followed by intestine, kidneys, thyroid, abomasum, spleen, skin, lungs and lowest in brain. The intensity of pathomorphological changes was proportional to the accumulated amount of arsenic in tissues/organs.

Despite limited understanding of therapeutic aetiopathogenesis of ulcerative colitis and Crohn's disease, there is a strong evidence base for the efficacy of pharmacological and biological therapies. It is equally important to recognise toxicity of the medical armamentarium for inflammatory bowel disease (IBD). Sulfasalazine consists of sulfapyridine linked to 5-aminosalicylic acid (5-ASA) via an azo bond. Common adverse effects related to sulfapyridine 'intolerance' include headache, nausea, anorexia, and malaise. Other allergic or toxic adverse effects include fever, rash, haemolytic anaemia, hepatitis, pancreatitis, paradoxical worsening of colitis, and reversible sperm abnormalities. The newer 5-ASA agents were developed to deliver the active ingredient of sulfasalazine while minimising adverse effects. Adverse effects are infrequent but may include nausea, dyspepsia and headache. Olsalazine may cause a secretory diarrhoea. Uncommon hypersensitivity reactions, including worsening of colitis, pancreatitis, pericarditis and nephritis, have also been reported. Corticosteroids are commonly prescribed for treatment of moderate to severe IBD. Despite short term efficacy, corticosteroids have numerous adverse effects that preclude their long term use. Adverse effects include acne, fluid retention, fat redistribution, hypertension, hyperglycaemia, psycho-neurological disturbances, cataracts, adrenal suppression, growth failure in children, and osteonecrosis. Newer corticosteroid preparations offer potential for targeted therapy and less corticosteroid-related adverse effects. Azathioprine and mercaptopurine are associated with pancreatitis in 3 to 15% of patients that resolves upon drug cessation. Bone marrow suppression is dose related and may be delayed. The adverse effects of methotrexate include nausea, leucopenia and, rarely, hypersensitivity pneumonia or hepatic fibrosis. Common adverse effects of cyclosporin include nephrotoxicity, hypertension, headache, gingival hyperplasia, hyperkalaemia, paresthesias, and tremors. These adverse effects usually abate with dose reduction or cessation of therapy. Seizures and opportunistic infections have also been reported. Antibacterials are commonly employed as primary therapy for Crohn's disease. Common adverse effects of metronidazole include nausea and a metallic taste. Peripheral neuropathy can occur with prolonged administration. Ciprofloxacin and other antibacterials may be beneficial in those intolerant to metronidazole. Newer immunosuppressive agents previously reserved for transplant recipients are under investigation for IBD. Tacrolimus has an adverse effect profile similar to cyclosporin, and may cause renal insufficiency. Mycophenolate mofetil, a purine synthesis inhibitor, has primarily gastrointestinal adverse effects. Biological agents targeting specific sites in the immunoinflammatory cascade are now available to treat IBD. Infliximab, a chimeric antibody targeting tumour necrosis factor-or has been well tolerated in clinical trials and early postmarketing experience. Additional trials are needed to assess long term adverse effects.
