The observation by Epstein and Barr (EB) of virus particles in Burkitt lymphoma cells in 1964 led 4 years later to the discovery that this virus was the long sought agent responsible for infectious mononucleosis. Pathophysiologically the EB virus specifically infects B lymphocytes of the immune system and induces perpetual multiplication of these cells if infection remains uncontrolled. The T lymphocytes, once sensitized against these virus infected cells, either kill them or suppress their continuous growth. During acute infectious mononucleosis, these stimulated T cells appear in the bloodstream as "atypical lymphocytes". If cell-mediated immunity is hampered by either congenital or acquired immunodeficiency the proliferative potential of EBV infected B lymphocytes may become uncontrolled and lead either to fulminant and lethal infectious mononucleosis or to polyclonal or monoclonal B cell proliferation. This later phenomenon appears to be the source of most of the lymphoma observed in transplant patients who are chronically immunosuppressed. Much remains to be understood of the mechanisms of EBV infections, which in some geographic areas lead to inapparent infections and in others to Burkitt lymphoma or nasopharyngeal carcinoma, while in temperate regions the clinical manifestations are those of infectious mononucleosis.

Thirty-five women aged 40 to 79 years with the carcinoma of the body of the uterus were before treatment examined for humoral immunity to find out if the diminished function of the immunological system and immunodeficiency lead to an increased proneness to malignant diseases. Concentrations of total serum proteins, electrophoresis of proteins, and the quantitative determination of G-, A-, and M- immunoglobulins were performed. Lower mean values of IgG (11.94 g/L) and IgA (1.91 g/L) were observed, whereas IgM concentrations did not reveal a statistically significant difference compared with healthy women. The classes, light and heavy chains, as well as immunoglobulin fragments were investigated by immunoelectrophoresis with monospecific antisera. The results revealed a significant accumulation of certain parts of the immunoglobulin molecule, such as gamma heavy chains (in 63% of patients), kappa (77%) and lambda light chains (37%), and fragments--Fab (37%), Fc (57%) i Fd (40%), showing no antibody properties in comparison with the control group of healthy women.

Widespread clinical trials of leavo-tetramisole (levamisole) as an immunopotentiating agent in rheumatoid arthritis, metastatic carcinoma, and immunodeficiency states have been complicated by agranulocytosis (AGC) in 2.5%-13% of patients. Other than a relationship with prolonged high dosage, very little is known regarding the pathogenesis of levamisole-induced AGC. Whereas leukoagglutination was negative, fluorochromatic microgranulocytotoxicity (GCY) tests were positive with serum from 10 of 10 acutely neutropenic patients. The antibody was IgM, reacted with 100% of unrelated granulocytes, but not with T or B lymphocytes. Some sera also reacted with monocytes and the myeloid cell line, K-562. Tests for antigen-antibody complexes or cold autoantibodies were negative. Although clinical evidence strongly suggests a haptene (drug) mechanism, in vitro mixing experiments were also negative. An alternative choice parallels the model of aldomet-induced Coombs'-positive hemolytic anemia. Finally, GCY first became positive 2-3 mo prior to the onset of AGC on two patients, suggesting the possibility of identifying those at risk well before the onset of neutropenia.

Between August 1975 and January 1981, 106 patients thought to have persistent or recurrent hyperparathyroidism underwent a total of 108 parathyroid re-explorations at the National Institutes of Health. These 106 patients had a total of 175 previous operations for hyperparathyroidism (156 cervical and 19 mediastinal). Nephrolithiasis (54% of patients) and bone disease (24% o patients) were the predominant symptoms. Arteriographic examination and selective venous sampling provided highly accurate localizing results in 33% of the patients, and were of some help in 64%. The final diagnoses after reoperation and re-evaluation were: single-gland disease in 58 patients, primary nonfamilial hyperplasia in 19 patients, familial hyperplasia in three patients, multiple endocrine neoplasia (MEN) Type I in ten patients, MEN Type II in two, parathyroid carcinoma in four patients, secondary hyperplasia in three patients, and familial hypocalciuric hypercalcemia (FHH) in two patients. The diagnosis was in doubt in five patients. In the 95 patients with unequivocal hyperparathyroidism, not due to parathyroid carcinoma, surgery eliminated hypercalcemia in 91 (96%). Two patients died after operation, one of disseminated candidiasis, and one patient, with an immunodeficiency, of sepsis. Five patients developed temporary, and one permanent, recurrent nerve damage; 41% of the patients were hypocalcemic, at the time of discharge from the hospital.

150 patients with histologically proven gastrointestinal tract (GIT) cancer, 150 patients with a variety of other malignancies and 150 normal subjects were screened for human immunodeficiency virus (HIV) and hepatitis B sero-markers. Only 1 patient with nasopharyngeal carcinoma proved to be HIV seropositive. Hepatitis B surface antigen (HBsAg) was detected in 18% (n = 26) of the GIT cancer patients, in 16% (n = 24) of the other cancer cases, and in 12% (n = 20) of the control group. There was no significant difference between the three groups (P 0.1). The HBsAg was detected mainly in patients with primary hepatocellular (25%), gastric (12%), rectal (10%), and colonic carcinoma (8%). Hepatitis B core antibody (HBcAB) was detected in 12% of the GIT cancer patients, in 11% of the other cancer patients, and in 13% of the control group. In this study, there was no association between HIV infection, hepatitis B infection, and GIT cancer.

Eccrine (sweat gland) carcinoma is a rare form of skin cancer that may be locally destructive. It is known to recur after resection and can metastasize to regional or distant lymph nodes. There have been two reported cases in association with patients immunocompromised as the result of organ transplantation (I. Penn: Prog Allergy. 37: 259, 1986). We report here the first case of sweat gland carcinoma in a patient infected with the human immunodeficiency virus.

Human immunodeficiency virus (HIV) related cancers in children are not as common and as well described as in adults. An HIV epidemic has been prevalent in Zambia since 1983-1984. To study the effect of the epidemic on the epidemiology of cancers in children a retrospective study was undertaken at the University Teaching Hospital (UTH), Lusaka, Zambia. All the histopathological records from 1980 to 1992 were reviewed and all cases of cancers in children less than 14 years of age were analysed. In order to define the effect of the HIV epidemic, the epidemiological features of various childhood cancers occurring before (during the years 1980-1982) and after (during the years 1990-1992) the onset of the HIV epidemic were compared. A significant increase in the occurrence of total childhood cancers was found. This is mostly due to a highly significant increase in the incidence of paediatric Kaposi's sarcoma (p = 0.000016), which is causally related to HIV infection, and a significant increase in the incidence of retinoblastoma (p = 0.02), which has an unknown relation to HIV infection. Though not yet statistically significant, there has also been a gradual and sustained increase in the incidence of non-Hodgkin's lymphoma, nasopharyngeal carcinoma, and rhabdomyosarcoma. There has been a significant reduction in the incidence of Burkitt's lymphoma. A prospective in depth epidemiological study of HIV related childhood cancers in Africa is urgently needed.

Peripheral blood T lymphocytes from 15 patients with gastric carcinoma and 6 normal healthy controls were evaluated for Interleukin-2 R gene expression. Total RNA was extracted from T cell-enriched fractions of patients as well as from control peripheral blood lymphocytes, with or without mitogenic stimulation. The presence of mRNA for IL-2 R alpha evaluated by Northern blot analysis revealed that unstimulated T cells expressed lower levels of IL-2 R mRNA than PHA stimulated T cells. Expression of both IL-2 R alpha transcripts (3.5 and 1.5 Kb) were either not detectable or only weakly detectable on T lymphocytes from patients even after mitogenic stimulation. In contrast, a significant rise in the expression of both IL-2 R alpha transcripts was observed on T cells from normal controls followed by mitogenic challenge. This paper reports on the defective IL-2 R alpha gene expression in gastric carcinoma patients, which may explain one of the causes of immunodeficiency associated with neoplastic transformation and progression.

The authors underline a synergism of HPV + HSV and HPV + CIN that, together with general immunodeficiency and local factors are responsible for the oncogenesis of cervico carcinoma. This thesis takes on importance after literature reports of an increase of 10% in viral infections from HSV and HPV with a middle incidence of the 1-2% in all the colpocytologic examination cases not in women between 18 and 65 years. To obtain a successful preventive treatment the authors recommend a colpocytologic examination each year, possibly in association with colposcopic, histologic and molecular studies in all HPV positive cases.

The objective of our study was to evaluate the prevalence of pleural effusions in patients with the acquired immunodeficiency syndrome, to correlate these effusions with any concomitant pulmonary diseases and to evaluate the role of cytologic examination in the diagnosis of the effusions. Twenty-eight of 389 (7.2%) human immunodeficiency virus-infected patients had pleural effusions and 27 of the 28 were suffering from concomitant pulmonary diseases. Those diseases were bacterial pneumonia (9), mycobacterial infection (7), non-Hodgkin's lymphoma (4) and Kaposi's sarcoma (2). Pneumocystis carinii pneumonia was diagnosed in two patients, and cytomegalovirus pneumonitis and pulmonary aspergillosis and small cell carcinoma in one patient each. Cytologic examination of pleural effusions provided conclusive diagnoses of mycobacterial infection in 2 of the 7 patients, of non-Hodgkin's lymphoma in 4 and of P carinii infection in 2.
