Charts of 126 patients with coccidioidomycosis were reviewed. Sixteen of these were patients who had malignancies, uremia, or a collagen-vascular disease and/or had received recent immunosuppressive drug therapy. The rate of disseminated infection was 50% in this group. (The dissemination rate was 14% in 110 control patients.) No case of dissemination occurred in patients who only had the above underlying diseases; all cases of dissemination were among those who had received immunosuppressive therapy. The dissemination rate in control patients was higher for patients age 40 or over than for younger patients. The dissemination rate showed no age-related difference, however, in patients treated with immunosuppressive drugs. The dissemination rate was similar in control patients of both sexes and uniformly higher for both immunosuppressively treated males and females. The dissemination rate did not appear to be influenced by the number of circulating lymphocytes if the patient had received immunosuppressive drugs. Patients with disseminated disease who had received immunosuppressive drugs were capable of producing a serological response to the coccidoiidal organism in high titer but none had positive skin test reactivity. Disseminated coccidioidomycosis is not uniformly fatal in the immunosuppressed host: half of our patients are alive an average of 33 months after diagnosis.

Life expectancy of diabetics since early childhood is differently judged. Out of 43 own patients with diabetes started between the first and third year of life, no less than 33 have passed their twentieth year of life; 16 patients are aged between 25 and 46 years; one woman patient lived to the age of 64! In all cases the duration of diabetes is more than 10 years, in 26 cases 20 years or more. In 24 cases angiopathy developed chiefly in the form of retinopathy, nephroapthy and arterial hypertension (none in 19 cases). 7 patients died of uraemia. While there is hardly any difference between the two groups (with or without angiopathy) as far as duration and quality of diabetes-control are concerned, in the angiopathy-group hereditary taint clearly prevails. The early beginning of diabetes does not at all represent an absolutely unfavourable symptom, rather the reverse (O. Imerslund).

One to ten years after laser coagulation for diabetic retinopathy, 229 type I diabetics (mean age 44.3 years) and 157 type II diabetics (mean age 65 years) were re-studied for morbidity and mortality (progression of late damage, duration of survival, cause of death). The duration of diabetes at the first laser coagulation averaged 23.1 years for type I diabetics (15.9 years for type II). Average period from the first laser coagulation to the re-examination was 6.5 years for type I, 5.1 for type II diabetics. Of those patients still alive 6.7% had gone blind (type II: 7.3%). 2.1% and 4.6%, respectively, were receiving dialysis treatment, while renal transplantation had been performed in 3.1 and 1.8%, respectively. Stroke was the most frequent macrovascular complications (8.4 and 16.5%), followed by leg amputation (3.6 and 14.7%) and myocardial infarction (3.7 and 18.3%). 83 patients had died: 35 (15.3%) type I and 48 (30.6%) type II diabetics. Causes of death were septicaemia 14.3% (0%), uraemia 11.4% (8.3%), myocardial infarction 14.3% (33.3%), heart failure 8.6% (29.2%) and stroke 5.7% (6.3%). 10.7% (24.2%) had died within the first 5 years after laser coagulation. Despite a lower incidence of blindness in patients with diabetic retinopathy, the vascular disease progresses in other vascular regions so that a large proportion of diabetics will develop renal failure or die early from macrovascular complications.

We performed a prospective study in 106 patients with acute stroke. The main purpose was to evaluate the associated diseases and to determine their prevalence and incidence in two different types of cerebrovascular disease: the intracerebral hemorrhage (HI) and ischaemic events (AI). The studied population included 54 men and 52 women with a mean age of 66.8 +/- 10.3 years. A clinical examination was performed in all patients by different specialists and all were submitted to diverse complementary tests, including a computed tomography scan of the brain (TAC) and an echocardiogram (ECO). We found 24 (23%) HI and 82 (77%) AI. In the past history, previous stroke were more prevalent in AI (p less than 0.01). Heart disease was present in 87 (82%) patients but, among them, only atrial fibrillation which was found in 19 (18%) patients, was significantly more frequent in AI (p less than 0.02). Hypertension (HTA) existed in 79 (75%) patients, respiratory complications and periferic vascular disease in 9 (8%), diabetes in 44 (42%) and dyslipidemia in 31 (29%) patients. No significant difference was found between the two groups of stroke regarding these diseases; however, there was a tendency for HTA and diabetes to be more prevalent in HI and for periferic vascular disease in AI. In the blood tests, high haematocrit was found in 35 (33%) patients, anemia in 21 (20%), hypercholesterolemia in 17 (16%), hypertrigliceridemia in 18 (17%) and uremia or creatinemia or ionic alteration in 32 (30%) patients, without any difference in their prevalence and incidence in the two groups of stroke. In conclusion, in this prospective study of patients with an acute stroke, there was 23% of HI and 77% of AI, a high prevalence of previous stroke, heart disease and HTA, but only the previous stroke and, within heart disease, the atrial fibrillation were significantly more frequent in the AI group. Also, periferic vascular disease had a tendency to be more frequent in AI, as well as diabetes and HTA had in HI.

Out of 334 patients operated on for PHPT in the years 1956-79, 34 (10.2%) had died before the end of the year 1980. In the sex and age matched control material of 334 patients operated on at the same time for varicose veins, appendicitis or haemorrhoids the mortality was 21 (6.3%). The difference in mortality between these groups was statistically significant (p less than 0.05). The mean age at death of the PHPT patients was 65 years and that of the control patients 67 years. The PHPT patients who died differed from the whole PHPT material in higher mean age at operation (61 years v. 53 years), higher preoperative serum calcium values (3.31 mmol/l v. 3.08 mmol/l), more frequently elevated serum creatine preoperatively (44% v. 17%) and higher mean weight of the removed adenomas (3300 mg v. 2000 mg). The PHPT patients who died had also more often the severe form of PHPT: 55% of the patients with hypercalcaemic crises and 24% of the patients with cystic bone changes had died, whereas the respective percentage was 4% in the renal stone group. Four of the PHPT patients had died of uraemia, and, in addition, four patients had progressive renal damage. 18 PHPT patients had died of cardiac disease, four patients of a cerebrovascular attack and one patient of other vascular disease. There were eight cardiovascular deaths in the control group (p less than 0.01). There were no differences in other causes of death, such as malignant tumours, between the groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Three labile diabetic patients had recurring episodes of altered sensorium. Each had severe cerebrovascular disease with superimposed metabolic derangements, including ketoacidosis, hyperglycemia without ketosis, mild uremia, and possibly cerebral edema. Two of the patients were examined postmortem. Severe leptomeningeal scarring, basal ganglial calcification and destruction of small intracerebral vessels without evidence of large vessel atherosclerosis were found unexpectedly in one patient, a rare occurrence in this country although recently reported from Europe. The other patient had large vessel atherosclerosis only. The clinical expression of the vascular disease was modified by concurrent abnormalities and reflected the sum total of the complexities which coexisted. The pathophysiology of the unconscious state necessarily depends on the inciting factors. Ketoacidotic coma is associated with depressed cerebral oxygen consumption. Spinal fluid pH is usually maintained during ketosis but is sometimes lowered inadvertently during bicarbonate therapy, with resultant coma. Other variables influencing the clinical expression, with or without ketosis, would include, among others, blood viscosity alterations, rapid decrements in blood sugar, and existing degrees of lactic acidosis. The increasing life-span of the juvenile diabetics, favorably influenced by improved management and recently by hemodialysis, may uncover vascular complications heretofore rarely seen and create additional diagnostic and therapeutic enigmas.

The generation of thromboxane B2 (TxB2) from its natural precursor, arachidonic acid, was studied in vitro in order to assess further the prostaglandin pathway in the platelets of patients with chronic renal failure. Some, but not all patients with conservatively treated uraemia synthesised significantly less TxB2 then controls and the same patients were also hypo-aggregable to arachidonic acid. The synthesis of TxB2 appeared normal in a group of patients on chronic ambulatory peritoneal dialysis (CAPD). In contrast, a group of patients on long-term maintenance haemodialysis produced significantly greater amounts of TxB2 and were hyper-aggregable to arachidonic acid, a finding which may be relevant to the high incidence of atherosclerosis and vascular disease in these patients.

We reviewed diabetic gangrene in 104 American blacks and found that the clinical features were similar to those reported for the general diabetic population. We observed, however, that there was a significant association of hypertension with above-knee and bilateral amputations in our patients (P less than .001 and .01, respectively), and that the mean blood pressure of the bilateral amputees (124.5 +/- 3.8 mm Hg) (SEM) was significantly higher (P less than .005) than that of the unilateral amputees (114.4 +/- 1.7 mm Hg). There results suggest a strong association of hypertension with far-advanced occlusive vascular disease of the lower limbs. Moderately severe anemia (hematocrit 20% to 30%) was associated significantly with primary above-knee amputation and mortality (P less than .02 and .05, respectively). Mortality resulted mostly from mixed causes (cardiopulmonary failure, uremia, sepsis, diabetic coma). The dead patients had significantly increased prevalence of cardiac disease (P less than .02), higher frequency of above-knee amputation (P less than .01), and a duration of diabetes (17.4 +/- 2.8 years) significantly longer (P less than .025) than that of the surviving patients (12.0 +/- 1.0 years).

Kidney tissue of acceptable quality was available from autopsies of 55 patients who had been followed prospectively for 3 to 15 years as participants in the University Group Diabetes Program, a study of vascular disease in Type 2 (non-insulin-dependent) diabetic patients. Slides were prepared for light microscopic reading by uniform histologic techniques, and then were randomly intermixed and coded with tissues identically prepared from matched non-diabetic subjects (morphologic controls). After independent review by three morphologists, the results were tabulated and assigned to one of four diagnostic groups: 1) typical diabetic nodular glomerulosclerosis; 2) mesangial changes suggestive of diabetes (diffuse lesion); 3) non-diabetic renal disease; 4) normal for age. Of the diabetic cases 31% (17 of 55) were found to show nodular glomerulosclerosis, and another 47% (26 of 55) showed suggestive changes; none of the morphologic control slides was read as showing nodular glomerulosclerosis, but some were judged to show suggestive mesangial (diffuse) changes. Although only 4 of the 17 diabetic patients with nodules had died of uraemia, many had hypertension, which may have contributed to their deaths from vascular disease. The patients with nodular glomerular changes also showed, on the average, the highest blood glucose levels during life. Type 2 diabetes in later life appears to be associated with a high risk for typical tissue changes of diabetic kidney damage, which may contribute significantly to morbidity and mortality and may be present before azotaemia and qualitative proteinuria have been recognized.

A retrospective multi-institutional study was performed to document and characterize the arterial vascular disease in the hypogastric-cavernous arterial bed and/or veno-occlusive dysfunction of the corpora cavernosa in patients with end stage renal disease. We evaluated 20 impotent patients (mean age 40 +/- 9 years) with chronic renal failure using pharmaco-cavernosometry and pharmacocavernosography (4 also underwent pharmaco-arteriography). Patients were divided into groups based on the treatment (14 with renal transplantation and 6 with hemodialysis or peritoneal dialysis), as well as by history of vascular risk factors (16 with and 4 without risk factors). Of the patients 19 revealed abnormal intracavernous pressure responses to repeated intracavenous injections of vasoactive agents implying vascular disease of the penis. Cavernous artery occlusive disease was found in 78% of the patients. All patients who underwent arteriography had diffuse atherosclerotic disease of the distal penile arteries. Corporeal veno-occlusive dysfunction was found in 90% of the patients, of whom 60% had diffuse pan-cavernous leakage involving the dorsal, cavernous and crural veins, glans penis and corpus spongiosum. This renal failure-associated vascular disease of the penis was found to occur independently of the presence of known systemic atherosclerotic vascular risk factors. Patients who underwent early treatment of the uremia by renal transplantation had vasculogenic impotence only in the case of rejection of the renal transplant, suggesting that early renal transplantation may delay or prevent the development of the penile vasculopathy. The most likely pathophysiology of the vascular impairment includes renal failure-associated atherosclerosis, and renal failure-associated hypoxia changes of the contractile (smooth muscle) and structural (collagen/elastin) components of the erectile tissue. Strategies for future research and clinical therapies are suggested.
