Clinical, paraclinical, and morphological investigations were carried out with a total of 12 cattle (9 calves and 3 cows) with an induced suppurative surgical infection caused by two strains of Corynebacterium pyogenes. It was established that such an experimental infection in cattle clinically ran a chronic course, involving predominantly the urinary and the digestive system as well as the joints. Morphologically, the infection was manifested as a chronic septicopyemia, with purulent nephritis and pyelonephritis, cystitis, splenitis, hepatitis, valvular meningoencephalitis, and absceses in various tissues and organs.

Caseous lymphadenitis was the most frequently encountered pathological condition in 3,720 feral goats examined during routine meat inspection procedures. Among 9 separate consignments of animals, the prevalence of infection averaged 7.4% (range 0.3% to 18.8%). The majority of lesions were seen in lymph nodes draining superficial body areas although many also occurred in internal nodes and organs. Corynebacterium ovis was isolated from 25 of 32 lesions submitted for bacteriological examination. Other conditions regularly encountered included pneumonia, cysticercosis, sarcosporidiosis and lice infestation, while myonecrosis, pleurisy, pericarditis, nephritis, hepatitis, cirrhosis and mite infestation were only occasionally found. A total of 171 serum samples were collected and tested against 17 antigens. Samples from 57.9% and 51.5% of goats showed positive serological reactions to the antigens for sarcosporidiosis and Q fever respectively.

A 6-day-old female (Bison bison) was inoculated with 10 million sporocysts of the B1 isolate of Sarcocystis cruzi originally obtained by feeding heart of a naturally infected cow (Bos taurus) to a laboratory-raised coyote. The bison became febrile, lethargic, and anorectic at about 25 days after inoculation of the sporocysts, and was euthanatized 3 days later. There were widespread hemorrhages, hepatitis, myocarditis, nephritis, and enteritis; intravascular meronts were found in the adrenal cortex and lamina propria of the small intestine. Another 7-day-old male bison was inoculated with 100,000 sporocysts of the same B1 isolate of S cruzi. Except for mild fever and transient diarrhea, the bison remained clinically normal. Sarcocysts were found at necropsy on day 76 after inoculation. It was concluded that S cruzi of cattle is transmissible to bison.

The general features of allergic drug reactions in man have recently been reviewed by Parker (85). By definition allergic drug reactions are produced by specific immunologic processes. Allergic drug reactions must be distinguished from adverse reactions due to overdosage, normal pharmacologic action, toxic metabolite formation, idiosyncrasy, nonspecific release of pharmacologic effector molecules, or drug interactions. The clinical manifestations of drug allergy are quite protean. In addition to classical manifestations of allergy such as serum sickness, anaphylaxis, contact dermatitis or urticaria, drug allergy may produce hemolytic anemia, thrombocytopenia, granulocytopenia, hepatitis, nephritis, pneumonitis, vasculitis, or neuritis where a single organ or cell type is affected. While many drugs produce reactions with suggestive of allergy, definitive experimental evidence either for or against mechanism is usually not available. Some of these reactions may involve allergic mediators released or produced nonimmunologically through pharmacologic, osmotic, or toxic effects on cells involved in immune inflammation (mast cells, basophils, phagocytes, and lymphocytes) or through nonspecific activation of effector molecules in extracellular fluid such as the complement proteins. Drugs may also induce the formation of autoantibodies through mechanisms that are largely obscure, but may in some instances involve the direct participation of the drug as a hapten and in other instances occur indirectly through a pharmacologic or toxic action on the cells responsible for immune homeostasis.

Loggerhead sea turtles (Caretta caretta) from the Atlantic seaboard (Florida to Massachusetts) were examined at the Marine Pathology Laboratory, University of Rhode Island, from March through December, 1980. Three genera of blood flukes (spirorchids) were found in 14 (33%) of the 43 turtles. Gross signs in heavily infected animals included cachexia, anemia and enteritis. Histopathological lesions were similar to those present in homeotherms with schistosomiasis. Granulomatous gastritis, enteritis, hepatitis, pneumonitis, and nephritis were present. Acute and chronic vasculitis accompanied metastasis of eggs. Infected animals had severe hepatic hemosiderosis, indicative of the anemia observed grossly. Evidence is presented that spirorchidiasis is prevelent in sub-adult loggerhead sea turtles, is responsible for extensive lesions and may be responsible for significant debilitation and mortality.

Maternal mortality was examined in a semi-urban Nigerian community over a 10-year period. Maternal mortality was defined as death occurring as the direct result of childbearing and measured per 1000 births. Abortions at below 20 weeks gestation were excluded. From 1966 to 1975, there were 90 maternal deaths out of 13,182, a rate of 6.8/1000. The hospital records of the Baptist Medical Center, located in the western part of Nigeria, were carefully reviewed and cross-checked with obstetric statistical records. Only 13 of the deaths occurred in hospitalized patients. 78 (80%) were due to direct obstetric causes; 12% were from nonobstetric causes. Anemia due to blood loss was the leading casue of death, accounting for 30, or 33%, of the deaths. Anemia, with or without congestive heart failure accounted for 7 deaths. Infection was responsible for 5 deaths. Ruptured uterus, preeclampsia, and eclampsia occurred in equal percentages, 10-11%. Indirect obstetric deaths, such as sudden death, accounted for 10 deaths. 50% of these were anesthetic deaths; the remainder were due to pulmonary embolism. Sickle cell intrapartum crisis was the cause of 1 death. Associated causes included featured pneumonia, nephritis, hepatitis, meningitis, enteritis, and cerebrovascular accident. Parity ranged from 0-11. 25 babies were salvaged in this series. Prevention continues to be the cornerstone in improving maternal mortality figures in developing countries. The Baptist Medical Center's model for providing maternal care is described briefly and is identified as responsible for the encouraging decline in the maternal mortality rate.

Two cases are reported of combined renal and hepatic failure following exposure to halothane anesthesia. Both patients presented with postoperative fever and rapidly deteriorating liver and kidney function. Both required peritoneal dialysis. Both patients died, and in both cases this was the second exposure to halothane. The pathologic features of the 2 cases were similar in that the liver changes were typical of those seen with halothane hepatitis and the renal lesion was similar to that of methoxyflurane nephritis. This is, to our knowledge, the third report of renal failure occurring after halothane anesthesia. Possible mechanisms regarding its toxicity are discussed.

Glomerular lesions associated with hepatic disease were evaluated. Among 752 consecutive patients with hepatitis and cirrhosis, nephritic urinary changes appeared in 1.0% of chronic hepatitis and 9.2% of cirrhotics, but none in patients with acute or subacute hepatitis. Kidney tissue was obtained from 141 cases, of which 59 underwent immunofluorescent studies. Except for a few with possibly coincidental glomerulonephritis, the main glomerular pathology was mesangial depositive or proliferative lesions with frequent circumferential mesangial interposition. The highest incidence (up to 69.2%) occurred in liver cirrhosis. The glomerular immunohistology was not necessarily homogeneous. In acute or subacute hepatitis, IgG or IgM, if present, was dominant. The more chronic the course the liver disease followed, the more frequently significant IgA deposition emerged, occurring in 60.5% of cirrhotics. The IgA positive cases often disclosed paramesangial dense deposits, which is one of the characteristics of primary IgA nephritis. Hepatic IgA nephritis exhibited a lower nephritogenicity and a proneness to show mesangial interposition when compared with primary or purpuric IgA nephritis. The possible origin of glomerular IgA associated with liver disease is discussed.

In Lyell's disease different clinical patterns can be observed: (a) an acute scarlatiniform erythema, on which more or less extended bullae rapidly appear; (b) a morbilliform erythema, with bullae; (c) the dermatosis can start under the features of an erythema exsudativum multiforme; (d) the eruption may begin as a psoriasis pustulosa. From an internal point of view, disturbances of the liquid balance and the blood electrolyte level may appear as a consequence of the important loss of water and serum. Toxic hepatitis, nephritis or myocarditis are possible complications. The origin of the disease is toxic or bacterial. This differentiation is important because the prognosis is much more favorable when the origin is bacterial than when the disease is due to medicines. A differential diagnosis between both etiologies may be achieved by histological examination: when the origin is a toxic one, we can find subepidermal blisters, while the blisters are located under the horny layer when the disease is of bacterial origin. The disease process is not clear in the toxic form. In cases induced by staphylococci, the epidermal lesions are caused by an epidermolytic toxin. The treatment will especially tend to restore the fluid and electrolyte balance; if there is a bacterial etiology, antibiotics will be necessary. Corticoids are to be avoided.

Hepatitis C virus (HCV) is the leading cause of non-A, non-B hepatitis among renal allograft recipients. We sought to identify and describe a proteinuric renal disease occurring in our HCV-infected renal transplant patients. Patients with proteinuria exceeding 1 g/day were identified from a cohort of 98 HCV-infected kidney recipients. Qualitative and quantitative reverse transcriptase polymerase chain reaction (RT-PCR) and restriction fragment-length polymorphism of the amplified RT-PCR product was performed to detect circulating HCV RNA, viral titer, and strain type, respectively. An immune complex nephritis (ICN) of the membranoproliferative pattern (MPGN) was found on five of eight biopsies. Two patients infected with the Hutch strain-type developed nephrotic-range proteinuria within three months posttransplant while the remaining three MPGN patients had been transplanted greater than 5 years prior to the onset of proteinuria. Testing for rheumatoid factors, cryoglobulins, hypocomplementemia, and circulating immune complexes failed to show a consistent pattern. Sucrose density gradient (SDG) equilibrium centrifugation was used to determine the buoyant-density of HCV virions from control (HCV-infected nonproteinuric recipients; n = 5) and nephrotic patients (n = 5). Whereas HCV virions from the control patients had a low buoyant density on sucrose gradients, a substantial percentage of the circulating HCV RNA from the MPGN patients was present in the high-density fractions in association with IgM and IgG. Treatment of the pooled high-density layers with NP40 followed by recentrifugation resulted in a shift of the HCV RNA to the medium-density layers. In conclusion, MPGN developed in five HCV-infected kidney recipients despite pharmacologic immunosuppression. Both the physicochemical properties of the HCV virions on SDG and their association with IgG and IgM in the high-density layers provide indirect evidence for the presence of circulating complexes of anti-HCV antibody and HCV antigen(s).
