Black-insulin-dependent diabetics under the age of 30 years attending a busy South African diabetic clinic were intensively screened for a 4-month period. In the 66 patients studied, the following previously undiagnosed conditions were discovered: cataract (1), peripheral neuropathy (16), retinopathy (8), tuberculosis (4) and anaemia (3). In addition, 29 (43,9%) were on insulin regimens that were not ideal. Attempts were made to improve glycaemic control, especially in those patients with complications, and defective insulin regimens were corrected. The screening programme was carried out with normal manpower and investigative facilities, and the extra time involved was not excessive. This programme could be used (in either an expanded or a limited form) in any diabetic clinic, and would probably considerably improve the health of young insulin-dependent diabetic patients.

Many patients with end-stage renal disease have now been maintained for 5 years or more with continuous ambulatory peritoneal dialysis (CAPD). Viewed initially as an experimental alternative to be used only when hemodialysis was not feasible, CAPD is now seen as the treatment of choice in an increasing number of situations. CAPD is suitable for self-care. The main concern in the early years--peritonitis--is now less frightening and less frequent (one episode occurring every 18 patient-months as compared with every 8 initially), and this has allowed chronic complications of CAPD, such as malnutrition and loss of the peritoneum's capacity for ultrafiltration, to come to light. As would be expected, among patients of advanced age and those who have heart disease or diabetes, survival rates tend to be lower than among other CAPD patients. However, hypertension seems to be more easily controlled, pre-existing anemia can be significantly ameliorated, and young children grow more normally than they do with hemodialysis. Diabetes-related changes in vision stabilize in most CAPD patients, and control of the blood glucose level is good; insulin is administered intraperitoneally. CAPD is thus showing itself to be a feasible form of long-term treatment for end-stage renal disease.

Three cases of diencephalic syndrome, associated with brain tumors, are reported in this paper. Case 1. A 2-2/12-year old boy was initially admitted to our hospital because of failure to thrive which began at the age of three months. Physical examination revealed emaciation (weight, 7.8 kg), irritability and pallor without anemia. Horizontal nystagmus was seen. Laboratory studies were normal except for abnormally high plasma growth hormone (p-GH) which was incompletely suppressed by hyperglycemia (induced by glucose) and was not elevated by hypoglycemia (induced by insulin). A low grade astrocytoma of the optic nerve compression the hypothalamus was partially removed. After the operation followed by irradiation, p-GH returned to normal both in its basal level and in its reaction to insulin loading, then his gain of weight was accelerated. He was readmitted, however, at the age of 6 8/12 years with headache and vomiting. Since subtotal removal of the recurrent tumor and irradiation, preoperative symptoms have disappeared up to the present (7 9/12 years old). Case 2. A 3-9/12-year old girl was initially admitted because of failure to thrive since the age of 2 years. Examination on admission revealed emaciation (10.5 kg), irritability and right hemiparesis. Laboratory studies were normal except for high serum cholesterol (290 mg/dl). (p-HG was not measured) The patient had been well after the subtotal removal of the hypothalamic astrocytoma except occasional headache until the age of 6 years. She was readmitted at the age of 9 years with progressive emaciation.(ABSTRACT TRUNCATED AT 250 WORDS)

The percentages of glycohaemoglobins in sixteen diabetic children are studied in different metabolic situations (hypoglycemia, hyperglycemia, coma, hemolytic anaemia) by two different methods; chromatographic method (stable and unstable glycohemoglobin), and colourimetric method (unstable glicohaemoglobin). The glycohaemoglobins appear as a useful parameter to assess the hydrocarbonate metabolism in infant diabetes; provided that alterations in the average life the red blood cells, do not exist. The chromatographic method is a quick, reliable technique in determining glycohemoglobins, although it is necessary to bear in mind that one may detect hyperglycemias changes dose to their realization, furnishing greater amounts than those which correspond to the stable form. Administration of slow insulin divided in two dose throughout the day appears more useful than administration of one dose in metabolic control of the diabetic.

The features of 41 proven or suspected cases of pancreatic glucagonoma and one possible case of renal glucagonoma have been reviewed. Glucagonoma is one form of islet cell neoplasm and involves pancreatic alpha cells. It may occur more frequently in women and is more likely to be malignant than insulinoma. Patients may present with glucose intolerance, an erythematous, eczematous dermatitis, glossitis, stomatitis, vaginitis and unexplained weight loss. Anemia, hypoproteinemia, hypoaminoacidemia and hypolipidemia may also be present. Malignant glucagonoma metastasizes frequently to liver. An evaluation for possible glucagonoma may be considered in a patient with the characteristic eczematous dermatitis, glossitis or stomatitis and glucose intolerance, an unusual or atypical history of diabetes mellitus, or hepatomegaly with other characteristics of glucagonoma. Initial evaluation may include measurement of fasting plasma glucagon concentration, and an oral glucose tolerance test with measurements of plasma glucose and glucagon levels. Extreme fasting hyperglucagonemia, and a paradoxical rise in plasma glucagon concentrations after glucose ingestion should strongly suggest the presence of glucagonoma. Radiographic demonstration of pancreatic glucagonoma is best carried out by celiac arteriography. Surgical excision of the tumor is the treatment of choice. Nonresectable lesions may respond to chemotherapy with streptozotocin. Treatment for the various dermatologic or metabolic complications of glucagonoma which include glucose intolerance, hypoproteinemia, hypocholesterolemia and anemia may not be satisfactory. Glucose intolerance is usually mild and may be adequately treated with dietary or insulin therapy. Rarely, glucagonoma with massive destruction of the pancreas or other factors may induce severe glucose intolerance. In contrast, the anemia, skin rash, and hypoproteinemia do not respond to conservative therapies tested thus far. Glucagonoma is a model for studying the importance of glucagon in causing the hyperglycemia of diabetes mellitus. Study of patients with glucagonoma does suggest that glucagon has some role in the etiology of hyperglycemia in diabetic states; however, as in studies on diabetes, investigations on glucagonoma do not demonstrate that glucagon has a primary role in producing severe glucose intolerance.

Sustained fetal hyperglycemia was produced in eight chronically catheterized fetal lambs (seven twins, and singleton) by means of direct fetal glucose infusion. In twin preparations, only one twin was infused, the noninfused twin serving as a simultaneous in utero control. Glucose infusions lasted 7.6 +/- 1.8 days and resulted in significant fetal hyperglycemia (from 20.3 +/- 1.1 mg/dl to 58.2 +/- 4.7 mg/dl, P less than 0.001). The magnitude of the hyperglycemia was linearly related to the glucose infusion rate. Elevations of fetal plasma glucose and glucose infusion rate were associated with a significant fall in fetal arterial oxygen content (P less than 0.001). In twin preparations studied, these relationships remained when the simultaneously sampled, noninfused twin was used as control. The fetal glucose-induced hypoxemia was not associated with fetal acidosis (tissue hypoxia) until the arterial oxygen content fell below 30% of baseline (mean base deficit in acidotic fetuses = 11.2 +/- 2.2 meq/liter). Although Pa02 fell in hypoxemic fetuses (from 13.5 +/- 1.2 mmHg to 9.7 +/- 1.2 mmHg), the difference was not significant. Fetal plasma insulin rose during hyperglycemia from 10.2 +/- 3.1 micro U/ml to a peak concentration of 26.2 +/- 3.3 micro U/ml, but this response was blunted in markedly hypoxemic fetuses. Neither fetal anemia nor hemoconcentration were evident in these preparations to account for the fall in fetal oxygen content.

Response to diet and drug therapy was assessed in a group of 85 Indian patients with non-insulin-dependent diabetes in the young (NIDDY). There was a significant decrease in fasting plasma glucose (FPG) values on therapy (pretreatment 13.3 +/- 0.5 mmol/l; post-treatment 9,7 +/- 0,4 mmol/l) (P less than 0,001). Prior to therapy the majority of patients had either moderate (40%) or severe (59%) diabetes; on therapy, the majority had either mild (21%) or moderate (62%) diabetes. Estimation of glycosylated haemoglobin (Hb A1) levels revealed that control was excellent (Hb A1 less than 10%) in 47% of patients and excellent or adequate (Hb A1 less than 12%) in 78%. Hb A1 levels correlated significantly with the FPG value (r = 0,78; P less than 0,001). In 8 patients with iron deficiency anaemia the HB a1 level did not fall within the correlation norms between Hb A1 and FPG. Treatment of the anaemia restored the correlative norms. Hb A1 levels were significantly higher in patients with microvascular complications (12,1 +/- 0,8%) than in those without any vascular complications (10,3 +/- 0,3%) (P less than 0,01).

Erythropoietin is known to be effective for the treatment of anemia in chronic renal failure, but the efficacy of erythropoietin for anemia in other diseases is not so great. Insulin exerts a growth promoting activity in various kinds of cells. In the present study, the effects of insulin on erythroid progenitors (colony forming units-erythroid, CFU-E; and burst forming units-erythroid, BFU-E) in human bone marrow were examined at various concentrations of recombinant human erythropoietin (rh-Epo) to clarify the relationship between erythropoietin and insulin. Human insulin stimulated the formation of CFU-E and BFU-E in the presence of three concentrations (0.25, 5, and 100 U/ml) of rh-Epo. Stimulatory effects of human insulin on CFU-E and BFU-E were also observed in the nonphagocytic and nonadherent bone marrow fraction (NP-NA fraction) and in the NP-NA and T cell-depleted fraction at each concentration of rh-Epo. Human insulin further stimulated the CFU-E and BFU-E growth in CD34+ separated bone marrow cells. These results indicate that the enhancing effect of human insulin on erythroid progenitors is not mediated through monocytes and macrophages or T cells, suggesting a direct action on erythroid progenitors.

Coeliac disease is a chronic disease characterized by small bowel villous atrophy which impairs nutrient absorption and improves on withdrawal of wheat gliadins and barley, rye and oat prolamins from the diet. Knowledge of the adult form of coeliac disease has greatly improved in recent years. Although this knowledge is not yet sufficiently widespread among referring clinicians, it has, over the past few years, allowed an increasing number of patients to be diagnosed with subclinical forms characterized by minor, transient or apparently unrelated symptoms. As a consequence, our views on the clinical and epidemiological aspects of this condition, the prevalence of which in the general population is believed to be close to 1 in 300, have changed and are still changing. Since it has been demonstrated that a strict gluten-free diet is protective against the complications of adult coeliac disease, it is important that even subclinical and silent forms are diagnosed and treated as early as possible. Non-invasive screening tests, such as anti-gliadin and anti-endomysium antibody estimation, should therefore be used systematically in groups considered to be at risk of coeliac disease. These include first-degree relatives of coeliac patients and patients with insulin-dependent diabetes mellitus, iron-deficiency anaemia, epilepsy with cerebral calcification, recurrent aphthous stomatitis and dental enamel hypoplasia. Other conditions will probably be identified in the near future.

A four-year-old, spayed female toy fox terrier presented with hyperglycemia and severe anemia. A diagnosis of immune-mediated diabetes mellitus was made based upon the finding of beta-cell specific antibodies. Immune-mediated hemolytic anemia was diagnosed based on findings of a regenerative anemia, spherocytosis, hyperbilirubinemia, hemoglobinuria, and bilirubinuria. The anemia resolved following two months of immunosuppressive therapy. The diabetes was treated with insulin for four months, after which time treatment was no longer necessary. However, the dog remained positive for beta-cell antibodies which may be a predictive marker for the recurrence of diabetes mellitus in the future.
