Proliferative diabetic retinopathy (PDR) is uncommon in patients younger than the age of 20 and has been rarely reported. Since 1969, 14 adolescents with severe PDR have been seen, the youngest of whom was 16 years old and the oldest, 19 years old. The shortest duration of diabetes mellitus prior to diagnosis of PDR was eight years. Ten patients had a positive family history of diabetes. Thirteen patients had suboptimal metabolic control. Ten patients had some degree of azotemia, seven were hypertensive, and six had proteinuria. Ophthalmic findings included advanced neovascular and fibrous proliferation on initial classification, and rapid progression to blindness-which was most frequently secondary to traction retinal detachment. In a small retrospective study, pituitary ablation may have offered greater preservation of vision than that observed in untreated patients.

This is a survey about all factors influencing the osmotic pressure. The actual osmotic pressure in the plasma of healthy individuals is regulated essentially by the natrium ions and the corresponding anions. The one exception is the dysfunctioning diabetes mellitus with distinctly advanced hyperglycaemia. Syndromes with an accompanying azotemia demonstrate a seeming hyperosmolality as long as the osmotic pressure is measured or calculated by the customary method. The real and present osmotic condition can only be calculated when the blood urea concentration is no longer considered. It is proposed that the term "corrected osmolality" be used for the values determined in this manner.

The parathyroid glands of 14 deceased diabetics were investigated as well as nine control non-diabetics. Various in character and degree histological alterations were observed during the morphological investigations of those glands: mild or better manifested hyperplastic alterations (six cases), microadenoma (one case), focal vasculary determined atrophia (two cases, total atrophia of involutive type (two cases), close to the control alterations (three cases). Hyperplastic alterations are established most frequently in the presence of diabetic nephropathia and azotemia. They could be explained with the development of a secondary hyperparathyroidism, associated with chronic renal insufficiency. In single cases, an effect of the disturbance of the calcium-phosphorus metabolism in diabetes is admitted. Changes in the parathyroid glands, from the type of generalized diabetic microangiopathy, is suspected in one of the deceased patients. Two microadenomas were found in another case, predominantly with dark basic cells. No dependence was established between the morphological alterations and the severity, diabetes form, nor with the presence of pyelonephritis. Certain dependence was established between the age of the deceased and the stage of the azotemia.

The past decade has seen a shift in the strategy for hypertension treatment from stepped therapy--a highly structured monolithic series of steps--to recommendations for a more individualized selection of treatment. Severe hypertension is a clear indicator to bypass traditional steps. Demographic factors, such as age, gender, and race, are often cited, but have proved to be less helpful. Concomitant medical conditions and problems are very common and are more often the crucial determinants in the selection of antihypertensive therapy. Coronary artery disease, diabetes mellitus, heart failure, azotemia, asthma, and chronic obstructive pulmonary artery disease, anxiety, and depression are all common, and each has implications for the selection of antihypertensive therapy. Blood pressure reduction is a surrogate for reduction of cardiovascular risk, and therefore, consideration of concomitant medical problems has extended to left ventricular hypertrophy, obesity, mild hyperlipidemia, and insulin resistance, as additional risk factors in hypertension. Consideration of all these factors makes it possible to individualize antihypertensive therapy in most patients today.

The occurrence of rhabdomyolysis and acute renal failure associated with cytomegaloviral infection is rare. A 27-year-old housewife was admitted to our hospital with complaints of thirst, muscle weakness, abdominal pain and oliguria. There was no past history of diabetes, drinking, fever or drug habituation and a negative family history. Laboratory tests revealed myoglobinuria, hyper-pancreatic type amylaseuria, hyperglycemia, azotemia and highly increased creatine phosphokinase in the plasma. She was treated with hemodialysis and insulin therapy. Serological studies showed a 4-fold increase in cytomegalovirus antibody titers 4 weeks after admission. Muscle biopsy specimens showed hyaline degeneration and infiltration of T cell lymphocytes in the muscle. Renal biopsy specimens showed acute tubular necrosis and some myoglobin casts. No cytomegalovirus antigen was found in renal specimens by immunofluorescence study. From these results, it was determined that a systemic cytomegalovirus infection triggered pancreatitis which caused diabetic ketoacidosis, rhabdomyolysis and acute renal failure.

Over the past decade we have seen a shift in the strategy for the treatment of hypertension, from stepped therapy--involving a highly structured, unvarying series of steps--to recommendations for more individualized treatment. How shall we accomplish that goal? Severe hypertension provides a clear indication to bypass earlier recommendations. Demographic data such as age, gender, and race, often cited, have proved less helpful. Concomitant medical problems, which are found in greater than 50% of hypertensive patients, are most often the crucial determinants in the selection of antihypertensive therapy. Concurrent coronary artery disease, diabetes mellitus, heart failure, azotemia, asthma, chronic obstructive pulmonary disease, borderline cognitive dysfunction, anxiety, and depression are all common. Each has implications for antihypertensive therapy. Moreover, blood pressure reduction is a surrogate for our real goal, which is reduction of cardiovascular risk. Thus, consideration of concomitant medical problems has extended to left ventricular hypertrophy, obesity, hyperlipidemia, and insulin resistance as additional risk factors in hypertension. Consideration of all of these factors makes it possible to individualize antihypertensive therapy in most patients.

Azotemia and diabetes mellitus are now well-known adverse reactions associated with Pentamidine treatment, especially since its prescription in case of Pneumocystis carinii pneumonia. We report the case of a 2 year-old boy, treated for kala-azar with pentamidine and N-methyl glucamine antimoniate who developed adverse effects, characterized by a nephrotic syndrome associated with the classic acute tubular necrosis, and transient diabetes mellitus.

Nephropathy is an established untoward event associated with intravascular administration of conventional high-osmolality contrast media (HOM). It has not been shown previously that lower-osmolality contrast media (LOM) are less nephrotoxic in a clinical setting. We evaluate the ability to replace HOM with LOM (in lower-extremity angiography) to reduce the incidence of nephropathy. We use multiple definitions for contrast-induced nephropathy (six different magnitudes of rise of serum levels of creatinine or blood urea nitrogen in various periods). The incidences of nephrotoxic effects with LOM vs HOM in patients with presumed risk factors, including preexisting renal insufficiency and diabetes, are evaluated also. When all patients are considered, the incidence of contrast-induced nephropathy for LOM vs HOM (defined as an increase in serum creatinine level greater than 0.3 mg/dl and greater than 20% on day 1, 2, or 3 and on day 5, 6, or 7, is 7% vs 26% (p = .001). When only patients with preangiography azotemia are considered, the incidence of contrast-induced nephropathy for LOM vs HOM is 10% vs 41% (p = .017); for diabetic patients, regardless of preangiography creatinine level, the incidence is 10% vs 31% (p = .012). Although contrast-induced nephropathy may develop even in a patient with no risk factors who receives LOM, LOM is associated with a decreased incidence of this condition, to various degrees, depending on the presence of risk factors.

The purpose of this study was to measure components of the renin angiotensin system in patients with type 1 diabetes mellitus, with and without nephropathy, to study the renal sensitivity to angiotensin II in uncomplicated type 1 diabetes and to investigate the short and long-term renal effects of angiotensin II reduction with angiotensin converting enzyme inhibitors in patients with diabetic nephropathy. In patients with type 1 diabetes without complications, plasma renin activity, angiotensin II and aldosterone levels were normal. In patients with diabetic nephropathy, renin levels were elevated, probably partly as a result of diuretic treatment. However, renin levels were also elevated compared to patients with other renal diseases who had similar treatment and degree of azotemia. The renal sensitivity to angiotensin II was normal in patients with uncomplicated diabetes. The reduction in glomerular filtration rate and renal plasma flow and increases in filtration fraction during A II infusion were equal to those in healthy controls. Nine days' captopril treatment in 15 patients with diabetic nephropathy induced an increase in renal plasma flow and a decrease in filtration fraction. The glomerular filtration rate remained unchanged. During 8 weeks' randomised enalapril or metoprolol treatment in 40 patients with diabetic nephropathy, enalapril treatment reduced proteinuria to half the initial value. Metoprolol treatment had no effect on proteinuria. Furosemide was also used and the dosage was adjusted to give equally effective blood-pressure control in both groups. During long-term treatment with captopril in patients with diabetic nephropathy, the rate of decline in kidney function over time was reduced to one-fourth the initial value even though the blood pressure was only slightly reduced. The renin angiotensin system appears to be functionally intact in diabetes mellitus and interruption by ACE inhibition reduces proteinuria both by blood pressure reduction and by an effect independent of systemic blood pressure. Long-term treatment might protect kidney function in diabetic nephropathy to a greater extent than would be expected from the blood-pressure-lowering effect alone.

Acromegaly was diagnosed in 14 middle-aged to old cats of mixed breeding. Thirteen (93%) of the cats were male and one was female. The earliest clinical signs in the 14 cats included polyuria, polydipsia, polyphagia, all of which were associated with untreated diabetes mellitus. All developed severe insulin resistance within a few months; peak insulin dosages required to control severe hyperglycemia ranged from 20 to 130 U per day. Other clinical findings weeks to months after diagnosis included enlargement of one or more organs (e.g., liver, heart, kidneys, and tongue) (n = 14), cardiomyopathy (n = 13), increase in body size and weight gain (n = 8), nephropathy associated with azotemia and clinical signs of renal failure (n = 7), degenerative arthropathy (n = 6), and central nervous system signs (i.e., circling and seizures) caused by enlargement of the pituitary tumor (n = 2). The diagnosis of acromegaly was confirmed by demonstration of extremely high basal serum growth hormone concentrations (22 to 131 micrograms/l) in all cats. Computerized tomography disclosed a mass in the region of the pituitary gland and hypothalamus in five of the six cats in which it was performed. Two cats were treated by cobalt radiotherapy followed by administration of a somatostatin analogue (octreotide), whereas two cats were treated with octreotide alone. Treatment had little to no effect in decreasing serum GH concentrations in any of the cats. Eleven of the 14 cats were euthanized or died four to 42 months (median survival time, 20.5 months) after the onset of acromegaly because of renal failure (n = 2), congestive heart failure (n = 1), concomitant renal failure and congestive heart failure (n = 3), progressive neurologic signs (n = 2), persistent anorexia and lethargy of unknown cause (n = 1), the owner's unwillingness to treat the diabetes mellitus (n = 1), or unknown causes (n = 1). Results of necropsy examination in ten cats revealed a large pituitary acidophil adenoma (n = 10), marked left ventricular and septal hypertrophy (n = 7), dilated cardiomyopathy (n = 1), arthropathy affecting the shoulder, elbow, or stifle (n = 5), and glomerulopathy characterized by expansion of the mesangial matrix and variable periglomerular fibrosis (n = 10).
