By continuous and simultaneous recording of nocturnal penile rigidity and circumferential expansion (tumescence), nocturnal penile rigidity and tumescence have been classified into 6 patterns: normal, dissociation, uncoupling, short episode, low amplitude and flat trace. The monitoring will be helpful to diagnose underlying disorders involving erectile impotence, if the pattern of nocturnal penile rigidity and tumescence are related with the disorders. This study analyzed the relationship between the pattern of nocturnal penile rigidity and tumescence and associated disorders in 105 patients with erectile impotence. Of 15 patients with central nervous system disorders, 9 (60%) had a pattern of short episode of rigidity. In 29 patients with cardiovascular disorders, the patterns of dissociation, low amplitude and flat trace were the main findings and observed in 41, 41, 35% of the group, respectively. No patients with diabetes mellitus showed normal pattern. Although the group of non insulin dependent diabetes mellitus (21 patients) had various patterns of rigidity and tumescence, the insulin dependent group (14 patients) mainly showed patterns of low amplitude (21%) and/or flat trace (71%). The continuous and simultaneous monitoring of penile rigidity and tumescence will be helpful, with an integral analysis of its pattern and other examinations, for accurate diagnosis of underlying disorders of organic impotence, besides for differentiation of organic impotence from psychogenic one.

Two-hundred-and-two impotent diabetic patients gave their consent to be investigated. Impotence is linked to diabetes mellitus in 58.9% of patients so all the other etiologies have to be systematically eliminated. Neuropathy or arteriopathy, when isolated, are found with the same frequency, but these 2 etiologies are often associated (47 patients). No statistical difference between IDDM and NIDDM was found. Mercury strain gauge plethysmography and venous occlusion coupled to ECG allows detection of arterial lesions in diabetic impotence. Patients agreed to submit to all of the various therapeutic possibilities. Combination of alpha-blockade and good glycemic control induced the best results.

Non-insulin-dependent diabetes mellitus is predominantly a disease of aging, with more than 70 percent of non-insulin-dependent (type II) diabetic patients older than 55 years of age. The prevalence of macrovascular, microvascular, and neurologic complications in outpatients with type II diabetes between the ages of 55 and 74 was compared with that in a similarly aged nondiabetic group of patients. The association between duration of diabetes, hypertension, age, and other putative risk factors that are prevalent in this elderly diabetic population and the occurrence of complications was explored. This cross-sectional survey confirmed a significant increase in retinopathy, neuropathy, impotence, and macrovascular complications in patients with type II diabetes. Within the diabetic population, duration of disease was associated with the occurrence of retinopathy and neuropathy, but not associated with such macrovascular complications as coronary artery disease. Gender, type of therapy, and previously identified risk factors for vascular disease such as hypertension had little impact on the prevalence of complications in this population. The notion that type II diabetes in the elderly represents "mild" diabetes with regard to complications must be discarded. Further identification of risk factors within this diabetic population may suggest therapeutic approaches that will prevent or ameliorate the development of complications.

The purpose of this study was: (1) to record GP opinions, practices and outcomes for the care of Type 2 Diabetes Mellitus (DM2), (2) compare practice facilities and process of care with a criterion of recommended competent care and (3) determine if there were any differences between vocationally registered and non-vocationally registered GPs. A random sample of 204 metropolitan doctors from 124 practices was selected and an audit performed on 467 of their patient records. GPs pursued good blood sugar control and advocated lifestyle changes before hypoglycaemic drugs. Over 80% regard uncomplicated DM2 as a condition for general practice management. However, only 15% conducted an annual diabetes check, 9% had a diabetic register, 6% a diabetic recall system and 8% used a diabetic health care checklist for monitoring their patients. The most commonly recorded processes of medical audit in the previous 12 months were: blood pressure (94%), duration of diabetes (72%), blood glucose (70%), diet (66%), body weight (56%), HBA1c (52%) and ophthalmoscopy (50%). The least commonly recorded processes of care were body mass index (5%), inspection of the feet (18%), enquiries about vaginitis or impotence (23%). The amount of exercise, alcohol and tobacco was recorded in only 34% of records. Hypoglycaemic drugs were used appropriately but the most commonly used drugs for treating hypertension in DM2 patients were thiazide diuretics and beta-blockers. Vocationally registered (VR) doctors had better records, higher process of care scores and more were willing to participate in the study than non-vocationally registered (NVR) doctors. However, there was no difference in metabolic control between patients from either group. The use of a Diabetic Health Care Checklist would improve diabetes care especially in the search for early complications and in the recording of HBA1c and other metabolic parameters. The drugs commonly used to control hypertension can have adverse effects on glucose and lipid metabolism and should be replaced with glucose and lipid neutral drugs.

In order to determine the local prevalence of polyneuropathy among adult outpatients with type II (non-insulin-dependent) diabetes mellitus, we applied a series of standardised measures to patients attending a multidisciplinary diabetes clinic. The study group comprised 94 men and 15 women; mean age, 70.6+/-7.8 years; mean duration of diabetes, 11.7+/-10.1 years; and mean HbA1c 8.3%+/-1.7%. Neuropathy Symptom Scores > or = 1 were present in 97% of patients (mean, 3+/-2; range, 0-12), and 95% had Neuropathy Disability Scores > or = 2 (mean, 27+/-19; range, 0-87). 52% of men reported impotence. Autonomic dysfunction on cardiovascular reflex testing was present in 46% of patients (39/84). Finger and toe vibration perception thresholds were greater than 3SD higher than mean thresholds measured in control subjects without diabetes in 43% and 58% of patients, respectively. Polyneuropathy, defined as lower limb sensory and motor nerve conduction velocity or latency outside mean +/-2 SD of that measured in age-matched controls, was present in 49% of patients (53/109). These results suggest that there is a high prevalence of polyneuropathy in Australian out-patients with type II diabetes mellitus. In this study, clinical assessment using Neuropathy Disability Scores was not diagnostically useful since only five patients had a normal score. Using nerve-conduction studies as the "gold standard" diagnostic criteria, the best alternative test for the presence of polyneuropathy was toe vibration perception threshold (sensitivity 74%, specificity 56%). In view of the emerging evidence that intensive glycaemic control reduces the rate of progression of polyneuropathy, we recommend that patients with type II diabetes mellitus have nerve-conduction studies performed for early detection of this important complication.

In Africa, a rise in complications of diabetes mellitus has gone in hand with the growing disease prevalence, clearly demonstrating the importance of assessing complications. Diabetes mellitus constitutes a major financial burden in developing countries in Africa with relatively limited resources. Ketoacidosis is observed in 24% of juvenile diabetes and is the inaugural sign in 76% of all cases, progressing to coma in 34%. Even in type 2 diabetes, acidoketosis occurs in 34% of the cases. Infection is particularly frequent and is often fatal in tropical Africa because of the involvement of Staphyococcus and Gram-negative microorganisms. Hyperleukocytosis and anemia are correlated with ineffective antibiotic therapy. Pulmonary tuberculosis is the ninth most frequent complication of diabetes. Overall mortality is 14.9 per 1000 person-years of diabetes. Mean age at death is 51.6 years for women and 57.6 years for men after a mean 12.5 year disease duration. Thirty percent of all deaths result from acute metabolic complications, infections and stroke. More than half of the patients with insulin-dependent-diabetes have retinopathy. Differences observed in patients with different ethnic origins is linked basically to unfavorable social and economic conditions that worsen the risk of poor blood glucose control. Retinopathy accounts for 32% of all ocular complications, similar to other African data and more generally in ophthalmology centers. The rate of neuropathy is high, reaching 70% in patients with microangiopathy. Impotence concerns 48.7% of the diabetic population with a mean age of 41.4+/-15.5 years. Coronary artery disease had a recognized influence on hemoglobin diseases, particularly when the coronarography is normal. Lower limb arteriopathy is observed in 18% of the diabetic patients.

Thirty-eight patients of NIDDM, 12 of IDDM and 10 healthy age matched controls were subjected to seven standardised autonomic reflex function tests. A scoring criteria was utilised for diagnosing and grading the severity of dysautonomia. Eight patients of IDDM and 24 of NIDDM had dysautonomia. One-third of the patients in each group had grade IV autonomic dysfunction. Severity of autonomic dysfunction was directly related to the duration of disease in NIDDM whereas in IDDM this relation was not seen. Peripheral neuropathy was almost always associated with dysautonomia in NIDDM. On the contrary, in IDDM dysautonomia was independent of peripheral neuropathy. Charcot's arthopathy, dysphagia, constipation and nocturnal diarrhea were always associated with evidence of dysautonomia. Other symptoms viz. gustatory sweating, postural dizziness and impotence did not necessarily indicate dysautonomia.

Penile tissue consisting of corps cavernosum (cc) and tunica albuginea (TA) was obtained from 35 impotent patients undergoing surgery for implantation of penile prostheses and was examined for nor adrenaline content. 10 patients were classified as a non diabetic non neuropathic group, on the basis of their clinical history and differential diagnostic symptoms which included Peyronie's disease, vascular disease, hypertension and psychogenic impotence. The nor adrenaline content was found to be significantly lower in tunica albuginea than the corpus cavernosum (P<0.02) in this group. The nor adrenaline content of corpus cavernosum from insulin dependent (IDDM) and non insulin dependent (NIDDM) diabetic neuropathic patients was also found to be significantly lower (P <0.02) than that of non diabetic non neuropathic patients. The nor adrenaline content of tunica albuginea however, was similar in both groups. A non significant association in the content of nor adrenaline in corpus cavernosum and tunica albuginea among IDDM and NIDDM diabetic neuropathics was also observed. These results provide evidence that an underlying neuropathic factor itself causes vascular as well as metabolic changes in the adrenergic nerves of the penis in diabetics due to neuropathy in addition to the effect of the disease and thus may contribute to the development of impotence in these patients irrespective of their type of diabetes.

Erectile dysfunction (ED) affects up to 70% of men with diabetes. However, the pathophysiology of ED in diabetes remains uncertain with both neuronal and vascular factors cited. We examined whether ED is an indicator of generalized endothelial dysfunction. A unique group of diabetic patients free from established conventional cardiac risk factors were investigated. Forearm bloodflow responses to nitroprusside and acetylcholine on 11 diabetic men with ED and 11 potent diabetic men were measured by venous plethysmography. Patient characteristics between the impotent and potent patients were similar except for Hba1c which was higher in the group with ED (8.35% vs. 7.03%: p = 0.003). Both groups showed increases in FBF to incremental infusions of nitroprusside and acetylcholine but the area under curve (AUC) were similar in the ED and the non-ED groups (p = 0.16 and p = 0.17, respectively). We demonstrated that ED in patients with type 2 diabetes is not associated with additional generalized endothelial dysfunction.

The steroidal mineralocorticoid receptor (MR) antagonists, spironolactone and eplerenone, decrease blood pressure, and attenuate the progression of chronic kidney disease (CKD). However, their use is limited by the fear of inducing hyperkalemia, gynecomastia, impotence, and amenorrhea. Esaxerenone is a novel nonsteroidal MR blocker (MRB) that has been recently developed. In vitro studies have revealed that esaxerenone has a high potency and selectivity for MR compared with spironolactone and eplerenone. Further studies have shown that esaxerenone elicits a strong blood pressure-lowering effect in hypertensive animals. Following the results from phase III clinical trials that esaxerenone is an effective and well-tolerated MRB in Japanese hypertensive patients, esaxerenone became clinically available in Japan from May 2019 for hypertensive patients. Thus, esaxerenone is a promising treatment option for patients with hypertension. In addition, both preclinical studies and phase II clinical trials have shown that esaxerenone elicits renoprotection independent of its antihypertensive effect. Recently, a phase III clinical trial (ESAX-DN study) has also demonstrated the safety and efficacy of esaxerenone in patients with type 2 diabetes and microalbuminuria. These data support future clinical development of esaxerenone for the treatment of renal disease.
