The clinical records and computerized tomography (CT) scans of 14 patients who presented with pyelonephritis to the Children's Hospital of Buffalo between 1976-1985 have been reviewed. The CT findings were as follows: multifocal pyelonephritis (6), lobar nephronia (6), focal pyelonephritis (2). All patients were treated with intravenous antibiotics, and none was surgically drained. Significant underlying diseases were present in 8 patients: diabetes (6), von Gierke disease (1), hepatorenal syndrome (1). The diabetic children tended to have focal disease. Ten voiding cystourethrograms were performed and only four demonstrated reflux. All children became afebrile within a few days. Lobar nephronia was as clinically responsive as pyelonephritis to antibiotic therapy. Urine cultures were most often positive, although there was 1 patient in each category with negative cultures. Blood cultures were rarely positive in any group. Gram negative organisms predominated. CT scanning in children with clinical acute pyelonephritis reveals three major imaging patterns. While distinct radiographically, they behave in a similar clinical manner. Lobar nephronia does not imply a worse clinical prognosis. Intravenous antibiotic therapy alone was adequate for all patients.

The diagnostic value of renal scintiscans in patients with acute or chronic renal failure has not been emphasized other than for the estimation of renal size. 131I OIH, 67gallium, 99mTcDTPA, glucoheptonate and DMSA all may be valuable in a variety of specific settings. Acute renal failure due to acute tubular necrosis, hepatorenal syndrome, acute interstitial nephritis, cortical necrosis, renal artery embolism, or acute pyelonephritis may be recognized. Data useful in the diagnosis and management of the patient with obstructive or reflux nephropathy may be obtained. Radionuclide studies in patients with chronic renal failure may help make apparent such causes as renal artery stenosis, chronic pyelonephritis or lymphomatous kidney infiltration. Future correlation of scanning results with renal pathology promises to further expand nuclear medicine's utility in the noninvasive diagnosis of renal disease.

Chronic alcoholism is accompanied by systemic involvement of the internal organs. Clinico-morphological forms of chronic alcoholism are distinguished on the basis of the prevailing organ pathology, Morphological data are presented, and pathogenesis of the lesions of the liver, heart, pancreas, and kidneys in patients with chronic alcoholism is analysed. The hepatic form may present alcoholic dystrophy, hepatitis or cirrhosis which are stages of progressing hepatopathy. The toxic and metabolic effect of ethanol is important in the pathogenesis of liver lesion. The cardiac form is characterized by the development of alcoholic myocardiodystrophy. In addition to the toxic influence of ethanol, hormonal and electrolyte changes and microcirculatory disorders play a role in its pathogenesis. Chronic calcifying pancreatitis in chronic alcoholism is associated with the effect of ethanol on the mediatory system. The renal form any present necronephrosis, hepatorenal syndrome, glomerulonephritis or pyelonephritis. Their pathogenesis is determined by toxicity of ethanol, circulation of immune complexes in the blood, or immunosuppression.
