Causes of death in renal transplant recipients. A review of autopsy findings from 1966 through 1985.
From 1966 through 1985, a total of 640 patients received 739 renal transplants at a single center transplantation program. Of 245 total deaths, a slide and chart review of all 116 autopsied cases (47%) identified the major causes of death as pneumonia (n = 43), sepsis (n = 32), hemorrhage (n = 15), peritonitis (n = 11), meningitis (n = 7), and pulmonary embolism (n = 5). Eighty-five (73.3%) of these patients died of complications directly associated with immunosuppression, almost all (n = 82) as a result of infection. Organisms most frequently identified at death were gram-negative bacilli (n = 72), Candida species (n = 23), cytomegalovirus (n = 17), enterococcus (n = 14), Staphylococcus aureus (n = 11), Aspergillus species (n = 10), Pneumocystis carinii (n = 5), and mycobacteria (n = 5). Significant associations were found between bolus steroid antirejection therapy and infection with Aspergillus cytomegalovirus. Diabetics had a higher incidence of fungal infections and bowel perforation than nondiabetics. During this 20-year period, overall one-year actual patient survival rates for the four respective five-year intervals increased dramatically (69.9%, 68.2%, 83.3%, and 91.8%), but the normalized death rate showed a smaller decrease for infectious vs noninfectious causes.

Increased lactate dehydrogenase isoenzyme 1 in serum and tumor tissue of a patient with small-cell carcinoma.
Histological examination of supraclavicular lymph node tissue obtained at biopsy from a 63-year-old man disclosed metastatic small-cell carcinoma. On admission and for four days subsequently, total lactate dehydrogenase (LD; EC 1.1.1.27) activity in serum was 6.5 times normal; studies of LD isoenzyme showed persistently increased LD-1, with LD-1 greater than LD-2. Isoenzyme electrophoresis of tissue homogenates prepared from the patient's tumor also showed the LD-1 greater than LD-2 pattern. Isoenzyme studies for supraclavicular lymph node tissue from five control subjects showed contrasting isoenzyme patterns as compared with the patients in whom LD-2, LD-3, and LD-4 predominated. Because these abnormalities were persistent, they differ from the temporal sequence for LD usually seen in myocardial infarction. This emphasizes the importance of repetitive sampling for clinical interpretation of data on this enzyme.

Intraocular tumors. A cytopathologic study.
The cytologic characteristics and histopathologic correlates of common ocular tumors were examined using (1) cytologic and histologic specimens prepared from enucleated eyes with retinoblastoma and melanoma, (2) cytologic specimens prepared from clinically obtained intraocular fluids from eyes with lymphoma, metastatic adenocarcinoma and retinoblastoma and (3) cytologic specimens prepared from orbital aspirates and cerebrospinal fluids from a patient in whom retinoblastoma had spread to the orbit and central nervous system. Retinoblastoma cells occurred singly and in clusters and were associated with abundant necrotic debris and portions of capillaries with perivascular tumor infiltrates. Melanoma cells frequently had prominent nucleoli and variable amounts of fine cytoplasmic pigmentation and were found individually and in groups. Lymphoma cells were noncohesive, with scant cytoplasm. Metastatic intraocular adenocarcinoma cells had well-defined borders, multiple nucleoli and vacuolated cytoplasm. In general, the cellular morphology in the cytologic and tissue preparations of the intraocular tumors correlated well with each other. The findings suggest that common primary and metastatic intraocular tumors can be differentiated in cytologic preparations.
