Forty-seven children with nonrhabdomyosarcomatous soft-tissue sarcomas (NRSTS) were treated by the Hematology-Oncology Service at Texas Children's Hospital, Houston, Texas, between 1958 and 1990. The male:female ratio was 1:1, and the median age was 11 years (3 weeks-16 years). A preexisting condition was found in 9/47 (19%) patients including neurofibromatosis (3), Down's syndrome (1), spina bifida (1), congenital facial asymmetry (1), giant pigmented nevus (1), juvenile onset diabetes mellitus (1), and acquired immune deficiency syndrome (1). The site of primary tumor was head and neck (3), trunk (33), and extremities (11). Twenty-four patients (51%) have survived free of disease with a median follow-up of 5 years (4 months-22 years). No patient whose disease recurred achieved a second remission. Of the 19 patients with group I disease, 16 (84%) survived free of disease. Wide excision of the primary tumor, with no microscopic residual disease, was associated with the greatest chance of disease-free survival.

The main principles of this hypothesis are very general: (i) signal-detection from background noise is one central issue in electronics; (ii) an important source of misunderstanding at different levels of communication is the fact that a given signal may have different meanings in different contexts; (iii) the unique role of chance in developmental biology is generally appreciated (37). In AIDS the basic defect would be the human specific inability to distinguish between the amino acid sequence of neuroleukin and peptides derived from the gp120 envelope protein of HIV, resulting in a slowly progressing failure of the CD4+ T cell-mediated immunity. In IDDM the postulated HLA class II-dependent hypersensitivity to immunological noise could predispose to random contacts between cells with a different signalling language. In the ensuing dialogue neuroleukin secreted by T cells would imply a continuous demand for insulin secretion to pancreatic beta cells resulting in diabetes. This hypothesis does not contradict with the provocative ideas proposed by Duesberg concerning the relationships between HIV and AIDS (24) and the known data on the genesis of IDDM.

Of 631 renal allografts performed at our center between January 1, 1979 and June 30, 1989, 368 were from cadaver donors (CAD) and 263 were from living-related donors (LRD). The recipients were almost equally divided among 3 ethnic groups: Black, Hispanic, and non-Hispanic, non-Black (primarily of northern European background). Recipient ages ranged between 1 and 70 years. In the CAD group HLA matching was emphasized so that no patient received a kidney with less than a 1 DR match, and for the entire series there was a mean of 2.4 of 6 HLA antigens matched between donor and recipient. All patients (LRD and CAD) received at least 3 pretransplant blood transfusions. Overall actuarial 10-year patient and graft survival were 68% and 48% respectively, with 72% patient and 56% graft survival for LRD and 58% patient and 36% graft survival for CAD recipients. Factors adversely affecting long-term graft outcome were: a) Black race. Overall 10-year graft survival was 23% versus 55% for non-Blacks (p = 0.008); b) Type I Diabetes before transplant. Overall 10-year graft survival was 35% versus 51% for nondiabetics; and c) Compliance. This was the most significant factor influencing long-term survival, other than death due to cardiovascular disease. In a non-Black, nondiabetic category of less than 36 years of age at transplantation (n = 169), 10-year patient survival in LRD and CAD groups was 95% and 85%, respectively, and graft survival was 78% and 70%, respectively. This was markedly different from the entire series (p = 0.008). Even in this group, 4 of the 17 graft losses (including mortality) were due to documented prolonged noncompliance in teenagers. The 6 other deaths that occurred were due to hepatitis/cirrhosis (2), CMV (3), and AIDS (1). Among the factors not influencing graft survival in the CAD group was HLA matching after the minimum requirements were fulfilled, either by comparing 1 with 2 DR antigens, or total HLA (1-6) antigens matched.

Insulin-dependent diabetes mellitus occurred following intravenous pentamidine treatment of two AIDS patients with Pneumocystis carinii pneumonia. Both patients also experienced drug-induced nephrotoxicity. Patients receiving pentamidine must be observed for multisystem dysfunction, including the onset of severe diabetes mellitus. Dosage adjustment or alternative therapy should be considered with the onset of toxicity.

A retrospective review of cranial CT scans obtained over a 4 year period in patients with acquired immunodeficiency syndrome (AIDS) and documented central nervous system (CNS) pathology is presented. The spectrum of diseases and the value of CT in detecting new, recurrent, and superimposed disease processes were determined. Fifty-one AIDS patients with confirmed CNS pathology were identified. Six of them had two coexistent diseases. Opportunistic infections predominated, especially Toxoplasma encephalitis and cryptococcal meningitis, while tumor was seen infrequently. Initial CT was positive in 76% of cases. In contrast to meningeal processes, where it was not very effective, CT was very sensitive in detecting most parenchymal disease processes. Characteristic although not pathognomonic CT patterns were found for certain diseases. Improvement or resolution of CT abnormalities in patients on medical therapy for Toxoplasma encephalitis correlated well with clinical improvement. Recurrence of CT abnormalities correlated well with medical noncompliance. The optimal contrast enhancement technique for detecting CNS pathology and for monitoring the effectiveness of medical therapy was also evaluated by a prospective study in which both immediate (IDD) and 1 hr delayed (DDD) double-dose contrast CT scans were compared. The examination found to be diagnostically superior in 30 of the 41 IDD/DDD studies was the delayed scan. It is recommended that CT be used routinely and with the 1 hr DDD scan to evaluate and follow AIDS patients with neurologic symptoms and/or signs.

Chimpanzees (Pan Troglodytes) and humans are closely related and belong to the same subfamily, Homininae. The approximately 1.8% genetic difference that exists between humans and the chimpanzees must be responsible for observed differences between these two species. It has been shown that chimpanzees can be infected with HIV, but AIDS has not been reported. Furthermore, the prevalence of autoimmune diseases may be low in this species. For instance, type II diabetes occurs, but type I (autoimmune) diabetes (IDDM), to our knowledge, has not been reported. In humans, susceptibility genes for MG and IDDM have been localized to the region between TNF and HLA-B. This region may also influence the rate of progression to death after HIV infection. We have identified differences in this region between humans and the chimpanzees. As shown by PFGE, the TNF to Patr-B region in the chimpanzees is approximately 130-160 kb shorter than the equivalent in humans. Southern and sequence analyses indicate that the deletions in chimpanzees (insertions in humans) include one copy of CL (approximately 10 kb) and the X sequences (< 30 kb). Obviously, other deletions/insertions (approximately 120 kb) need to be identified. Since CL has been shown to be transcribed, the results imply the lack of the gene or, at least, a different gene copy number in the chimpanzees, and we propose that such differences may be relevant to the observed functional differences. We demonstrate here a strategy to identify critical genes responsible for disease development.

Injectable gallium (Ga) nitrate, approved in the United States for the treatment of hypercalcemia of malignancy, has been known for more than 2 decades to have immunosuppressive properties. At therapeutic doses, it has few adverse effects, although high-dose infusions may result in severe nephrotoxicity, particularly in patients who are not adequately hydrated, and severe anemia. In animal models, Ga has been shown to have efficacy in the treatment of adjuvant arthritis, type 1 diabetes, experimental autoimmune encephalomyelitis, experimental pulmonary inflammation, cardiac allograft rejection, experimental autoimmune uveitis, endotoxic shock, and systemic lupus erythematosus. Clinical trials have demonstrated efficacy in Paget's disease of bone and activity against some malignancies, including epithelial ovarian carcinoma, non-squamous cell carcinoma of the cervix, bladder cancer, and non-Hodgkin's lymphoma. Other clinical trials underway include studies of sarcoidosis and rheumatoid arthritis. Future studies should be conducted not only in other autoimmune diseases, such as multiple sclerosis, but also in graft-versus-host disease, leprosy, and acquired immunodeficiency syndrome (AIDS).

Until recently, there was a paucity of data on the epidemiology of diabetes mellitus in Africa. Over the past decade, information on the prevalence of type 2 diabetes has increased, albeit still limited, but there is still a lack of adequate data on type 1 diabetes in sub-Saharan Africa (SSA). For type 2 diabetes, although the prevalence is low in some rural populations, moderate and even high rates have been reported from other countries. In low diabetes prevalence populations, the moderate to high rates of impaired glucose tolerance is a possible indicator of the early stage of a diabetes epidemic. Diabetes prevalence is higher in urban, migrant and African-origin populations living abroad. There is evidence for a significant association with preventable and modifiable risk factors viz. adiposity, known diabetes, physical activity; but a dearth of data on the impact of dietary and genetic factors. For type 1 diabetes, the limited available data suggest that in SSA the frequency is low and that age of onset occurs later than in the western world. There is evidence for the role of genetic and immunological factors in its pathogenesis. The impact of HIV/AIDS on projected estimates for diabetes prevalence in Africa needs to be established.

Insulin-like growth factor 1 (IGF-1, somatomedin C) belongs to a family of polypeptide hormones, which are structurally close relatives of insulin. Circulating IGF-1 is synthesised in the liver. Serum level of somatomedin is regulated by: growth hormone (GH), insulin and nutrition. It is also produced locally by most tissues, where it acts in auto- and paracrine manner. IGF-1 takes part in regulating growth after binding to IGF receptor during embryonic development and after birth. In adults somatomedin plays a role in the process of regeneration, mainly in the case of connective tissue. It is also a weak mitogen for most cultured cells and it can act like insulin. Somatomedin circulates in plasma in complex with a family of binding proteins. 85-95% of total IGF-1 is found in the complex consisting of IGF-1, binding protein 3 and ALS. This complex is a store of IGF and limits the access of somatomedin to specific receptors. After binding with IGFBP-1, IGFBP-2 and IGFBP-6, IGF-1 passes through epithelium and reaches the target cells. The serum concentration of this protein appears to be inversely related to insulin level. IGFBP-1 can modulate IGF growth-promoting effect. IGF and its binding proteins are important in the diagnosis and treatment of some pituitary diseases, catabolic states such as malnutrition, burns, AIDS, polytrauma and tumors with hypoglikemia. Insulin-like growth factors may be involved in the etiopathogenesis of diabetes and in diabetes complications. Abnormalities in functioning of GH-IGF-1 axis are regarded as a cause of the growth retardation in children with poor metabolic control of type 1 diabetes, insulin-resistance, dawn phenomenon and fat disorders. rhIGF has been used in the treatment of some diseases bringing positive results.

There is a paucity of data describing the incidence of pre-existing diseases or risk factors and their effects in trauma patients. We conducted a prospective study to determine the incidence of such factors in critically ill trauma patients and to evaluate their impact on outcome. The study, performed over a 2-year period, examined the hospital course of all trauma patients admitted to the ICU. Multiple risk factors were evaluated and analyzed via multivariate regression analysis. Outcome was evaluated by infection rate, hospital length of stay, ventilator days, and mortality matched for age and Injury Severity Score (ISS). A total of 1172 patients (73% blunt injury) were enrolled over the study period. Of these, 873 (74.5%) were male. The mean age was 42.5 years with an ISS of 19.8. Tobacco use (24%) was the most common risk factor identified, followed by hypertension (HTN, 17%), coronary artery disease (9%), chronic obstructive pulmonary disease (COPD)/reactive airway disease (4%), non-insulin-dependent diabetes (NIDDM) (4%), insulin-dependent diabetes (IDDM) (3.2%), cancer (3%), liver disease (2%), and HIV/AIDS (1.4%). Of these risk factors, IDDM was found to be an independent risk factor for infection (0.004) and ventilator days (0.047), increasing age was found to be an independent risk factor for hospital length of stay (0.023) and mortality (<0.001), and HTN was found to be an independent risk factor for increased ventilator days (0.04). In addition, COPD/reactive airway disease was found to be an independent predictor of ventilator days, infection, and ICU days (P < 0.05). Thus, increased age, IDDM, COPD, and HTN are most predictive of outcome in critically ill trauma patients. With our aging population it is becoming increasingly important to identify pre-existing risk factors on admission in order to minimize their effects on outcome.
