A personal series of 6780 patients with diabetes mellitus is reported. Of these 1410 were thought to have insulin-dependent (Type 1) diabetes and 4926 non-insulin-dependent (Type 2) diabetes. Among the former, 128 patients were only diagnosed when in severe ketoacidosis or coma. In 116 patients the diabetes was diagnosed in pregnancy. Chronic alcoholism was an aetiological factor in 75 patients; in 52 it led to the diagnosis being made, and it complicated treatment in 129 additional patients. In the patients with Type 2 diabetes whose treatment was stabilized 23.5% were having insulin injections, 44.5% tablets, and 32.0% diet only. Sight-threatening retinopathy developed in 21.3% of patients with Type 1 and 7.9% of those with Type 2 diabetes. The rate of developing sight-threatening retinopathy was 1.1% of patients per year. Blindness occurred in 0.28% of patients with Type 1 diabetes per year and 0.097% per year in Type 2 diabetes. If the mean survival of patients with retinopathy going blind is 7.5 years, this would mean 7500 people in the UK blind from diabetic retinopathy. There was a striking drop in the annual incidence of blindness after 1970 coinciding with the introduction of specific treatment for diabetic retinopathy. Juvenile cataract developed in 1.7% of patients who developed Type 1 diabetes before 30 years of age. Clinically important diabetic neuropathy developed in 17.4% of patients with Type 1 and 11.6% of those with Type 2 diabetes. The main features were paraesthesiae and numbness (49%), neuropathic ulceration (37%), pain (5%), autonomic symptoms (5%), and amyotrophy (4%). Oculomotor palsies and mononeuropathies were noted. Foot ulceration occurred in 81 patients with Type 1 and 279 of those with Type 2 diabetes. Charcot changes in the feet were noted in 21 patients. Major amputations were needed in 18 patients with Type 1 and 60 with Type 2 diabetes. Proteinuria believed to be due to diabetic nephropathy developed in 12.8% of patients with Type 1 and 4.7% of those with Type 2 diabetes. The prevalence of early renal failure was 4.6% and 1.4%, respectively. Coronary artery disease was noted in 9% of patients with Type 1 diabetes, and was more common in those who developed diabetes after 20 years of age. Myocardial infarction was as common in women as in men. In Type 2 diabetes coronary artery disease gave rise to symptoms in 19.1%, and myocardial infarction was more common in men.(ABSTRACT TRUNCATED AT 400 WORDS)

Diabetic femoral neuropathy is an uncommon, unpleasant and sometimes disabling condition, on account of both pain and muscular atrophy, whose long-term prognosis has not previously been documented. We have reviewed a group of 27 patients up to 14 years (median 62 months) after diagnosis; 18 of these were re-examined after an average of nearly 4 years (median 45 months). The condition was more common in non-insulin-dependent diabetics (88 per cent), in men (59 per cent) and in older patients (median age at diagnosis 64 years). The neuropathy was bilateral (10 cases) or unilateral (17 cases); five patients with unilateral neuropathy developed femoral neuropathy on the opposite side, usually within a few weeks of the first episode. Recovery was apparent after 3 months and usually complete by 18 months; only two of the 27 patients had severe relapses. No patients remained disabled, although there were minor residual symptoms and signs in half of the patients (2 cm reduction in thigh circumference and diminished reflexes). The outlook for femoral neuropathy, even in its most severe form, is therefore very good: residual features are demonstrable but do not cause symptoms, and relapses after the first few weeks are very rare.

Chronic pancreatitis is difficult to treat in patients with a nondilated duct. Patients experiencing intractable pain unresponsive to or judged untreatable by lesser procedures must decide between total pancreatectomy and resultant diabetes or a continuation of their pancreatitis. From 1977 through 1990, 26 patients underwent extensive pancreatectomy and dispersed pancreatic islet tissue autotransplantation for treatment of chronic pancreatitis pain and prophylaxis of surgical diabetes. Of these 26 patients, total (Whipple) or near-total (greater than 95%) pancreatectomy was performed in 24 patients. Of these 24 patients, pain relief could be assessed in 21 patients at 5 to 155 months (mean, 5.7 years), and 19 patients (90%) reported partial or complete remission. Of the patients who underwent total or near-total pancreatectomy, islets were injected intraportally in 22 patients and into the renal subcapsule in two patients. The latter two patients have required insulin since surgery. Of the other 22, one patient died from a complication of the pancreatectomy. Nine of the 21 evaluable recipients of intraportal islet autografts were insulin independent for at least several months after surgery. Five patients are currently insulin independent at 6 years, 4 years, 1.5 years, 9 months, and 5 months after surgery. Of the other four patients, one patient died insulin independent at 6 years, and three patients required insulin beginning 8 to 18 months after surgery. Insulin independence correlated with the number of islets recovered, which in turn correlated inversely with the degree of pancreatic fibrosis. Of our four most recent patients, three patients had mildly to moderately fibrotic glands, and higher numbers of islets were obtained. After total (Whipple) pancreatectomy, these three patients are insulin independent. A liver biopsy was performed in one patient 8 months after total pancreatectomy and islet autotransplantation; numerous clusters of islet cells staining strongly for insulin and glucagon were detected within portal triads on both wedge and needle biopsy specimens. Morbidity related to the intraportal-dispersed pancreatic islet tissue transplantation was low (no disseminated intravascular coagulation, significant portal hypertension, or hepatic dysfunction). Islet autotransplantation can be an effective and safe adjunct to extensive pancreatic resection for those patients who risk surgical diabetes for relief of their chronic pancreatitis pain.

This study examined prospectively the effects of different anaesthetic techniques on the plasma concentrations of adrenocorticotrophic hormone (ACTH), aldosterone, cortisol, dehydroepiandrosterone (17-DHEA), insulin, prolactin, thyroxine, triiodothyronine as well as the effects on the plasma concentrations of epinephrine, norepinephrine and dopamine. Forty patients for trauma surgery were randomly allocated to one of the following anaesthetic techniques: halothane-N2O/O2-anaesthesia, isoflurane-N2O/O2-anaesthesia, midazolam-fentanyl-N2O/O2-anaesthesia, midazolam-ketamine-N2O/O2-anaesthesia or tramadol-N2O/O2-anaesthesia. The results of this endocrinological study demonstrate differences in the quality of the anaesthetic techniques used even without extreme stress situations for the patient. The elimination of pain can reduce, but not avoid, endocrinologic response to stress. Endocrine values are influenced by a lot of different control mechanisms. It is not always possible to distinguish between pharmacologic and indirect or direct effects of anaesthesia or surgery. For this reason, single plasma hormone levels should not be overvalued and equated with "stress" indicators, which is a much more complicated issue.

The best methods of contraception for women with insulin-dependent diabetes mellitus and gestational diabetes are discussed, with results of clinical trials in both types of patients. Women with IDDM require effective contraception since there are serious risks both to the mother and the fetus in case of unplanned pregnancy. For women reliable enough to use them consistently, barrier methods are satisfactory. IUDs are the choice for most diabetic women. In a trial of copper-T 200 IUDs in 103 diabetics compared to 119 normal controls, the effectiveness, expulsion rate, removals for bleeding and pain, and continuation rates were comparable. It was noted that there were no added infections in the diabetic group, who have an increased risk for infection generally. Oral contraceptives may worsen glucose tolerance, due to the effect of the progestogen decreasing diabetes, except in women with history of gestational diabetes. The authors found that a triphasic pill, with lower progestin dose, decreased insulin sensitivity more than did a combined pill, in both normal women and in those with previous gestational diabetes. Since natural estrogens, as used in estrogen replacement therapy in climacteric women, do not affect glucose tolerance as much as synthetic alkylated estrogens (i.e., ethinyl estradiol), the authors tried a combination of 4 mg estradiol, 2 mg estriol and 3 mg norethisterone for contraception in diabetic women. This experimental combination was compared with a low dose ethinyl estradiol-norethisterone monophasic, a progestin only pill, and an ethinyl estradiol-levonorgestrel triphasic. There were no differences among the groups in fasting plasma glucose, 24-hour insulin requirements, HbA1C levels, LDL, or free fatty acids. VLDL and HDL cholesterol and total cholesterol decreased in the natural estrogen group. There was a small, significant increase in LDL, VLDL and total cholesterol in the combined group. The authors also have preliminary results of a trial of a low-dose monophasic with ethinyl estradiol and gestodene, showing no adverse effects on glycemic control in IDDM patients. Thus low dose progestin, triphasic and natural estrogen-progestagen combination oral contraceptives can be recommended as safe to diabetics.

Life-long sequential changes in glucose tolerance and insulin secretion were investigated in genetically obese Zucker rats (fa/fa) fed a diabetogenic diet rich in lard and sucrose. Comparisons were made with lean littermates (Fa/-) receiving normal chow diet. At 3-month intervals, seven to nine lean and obese rats had two permanent venous catheters implanted, allowing stress- and pain-free sampling of blood before, during, and after substrate administration. Intravenous glucose, iv arginine, and oral glucose tolerance were tested. The obese rats progressively developed hyperglycemia and severe hyperinsulinemia; their basal glycemia reached 8.8 +/- 1.1 vs. 5.8 +/- 0.2 mmol/liter in the lean rats at 46 weeks of age; respective insulinemia was 287.7 +/- 61.9 and 18.1 +/- 2.8 mU/liter (mean +/- SD). In the obese rats a distinct loss in glucose tolerance was seen with progression of age in spite of rising stimulated insulin secretion, which suggests progressive development of insulin resistance without exhaustion of B-cell secretory capacity. Absence of insulin deficiency was also suggested by immunohistochemical staining of pancreatic tissue specimens from obese rats, which showed large populations of insulin-containing cells. Like the obese animals, lean rats exhibited a decrease in insulin sensitivity with age. Relating basal individual glycemia and insulinemia, a rise by 1 mmol/liter in glycemia was associated with a 8.8-fold rise in basal insulinemia in lean rats, but only with a 1.8-fold increase in obese rats. Similar correlations for stimulated glycemia and insulinemia suggest impaired glucose sensitivity of pancreatic B-cells in obese vs. lean rats. In conclusion, hyperglycemia and hyperinsulinemia in insulin-resistant obese Zucker rats on a diabetogenic diet are not characterized by quantitatively deficient B-cell secretory capacity, but, rather, by impaired B-cell sensitivity to glucose with qualitatively intact regulation of glycemia and insulinemia at elevated plasma concentrations.

In order to determine the features that characterize refractory hypertension (RH), patients aged less than 65 years in a hypertension clinic were screened. Thirty-six patients on triple drug therapy with a supine diastolic blood pressure (DBP) of greater than or equal to 5 mmHg above an identified target pressure (90-100 mmHg), or a systolic blood pressure (SBP) greater than or equal to 170 mmHg for the last 6 months (greater than or equal to 3 measurements) underwent a thorough clinical investigation. The frequency of renal artery stenosis (RAS) in the RH patients was 30%. The non-RAS patients had a low occupational status, 76% being either manual workers or unskilled non-manual workers (reference group: 42%; P less than 0.01). They were more obese (body mass index (BMI) 28.8 vs. 25.8; P less than 0.01), and had a longer duration of hypertensive disease. RH patients had a higher prevalence of non-insulin-dependent diabetes mellitus (18 vs. 6%; P less than 0.05), and showed a higher prevalence of nervous complaints and mental distress (44% vs. 12%; P less than 0.001) and musculo-skeletal pain (39% vs. 7%: P less than 0.001). It is suggested that refractory hypertension should be investigated and treated bearing psychosocial factors in mind, concurrently with a screening for secondary hypertension.

Observations have been made on a selected series of insulin-dependent patients with neuropathy, subdivided into three groups: (1) severe autonomic neuropathy with an accompanying painless sensory neuropathy; (2) severe autonomic neuropathy with a chronic painful sensory neuropathy; and (3) chronic or acute painful sensory neuropathy with no autonomic neuropathy. All three groups showed a loss of large and small myelinated nerve fibres in sural nerve biopsy specimens which was greater in Groups 1 and 2. Regenerative activity was prominent in all three groups, but least in Group 3. Teased fibre studies showed evidence both of axonal regeneration and remyelination. Active fibre degeneration was rare. Measurements of g ratio (axon diameter:total fibre diameter) gave no indication of axonal atrophy. The density of unmyelinated axons was reduced in all three groups, as was their median diameter. Vibration sense threshold was positively correlated with the total number of myelinated fibres and thermal sensory threshold with median unmyelinated axon diameter but not with total unmyelinated axon numbers. No correlation between the occurrence of pain and active degeneration of myelinated fibres or with regenerative activity either in myelinated or unmyelinated axons was detectable. Assessment of differential loss of large or small myelinated nerve fibres was difficult because of the presence of large numbers of small regenerating myelinated axons. The results are discussed in relation to the concept of 'diabetic small fibre neuropathy' and the causation of pain in diabetic neuropathy.

Plasma growth hormone (GH), insulin, prolactin and blood glucose levels were measured to evaluate postoperative pain relief either with epidural morphine or systemic analgesics in 16 patients who underwent gastrectomy. Continuous epidural morphine with a pump (CADD-PCA, Model 5200P, Pharmacia) was given to eight (epidural morphine group) patients. A bolus of epidural morphine was administered through an indwelling thoracic (Th8.9) catheter at 3 hrs prior to the expected end of surgery, which was followed with continuous epidural infusion of morphine at a rate of 0.167-0.042 mg.hr-1 with the pump during and after anesthesia and surgery with gradually decreasing dose until the third postoperative day. The remaining eight patients (systemic analgesics group) repeatedly received intravenous or intramuscular pentazocine and buprenorphine when needed. Plasma GH levels increased significantly only on the first postoperative day in both groups. Plasma insulin levels increased significantly on the first postoperative day in both groups. Blood glucose levels increased significantly at the end of surgery and during the following three postoperative days in both groups. There are no statistical differences in plasma GH, insulin and blood glucose levels between the two groups. Plasma prolactin concentrations increased significantly at the end of surgery and they were significantly higher in the systemic analgesic group than in the epidural morphine group. They, however, returned to the previous day's levels on the first postoperative day in both groups. Our study suggests that continuous epidural infusion of morphine has no suppressing effect on postoperative changes in plasma GH, insulin, prolactin and blood glucose levels as compared with systemic analgesic regimen.

Four patients (two men and two women, aged between 54 and 75 years), known to have type II diabetes since two to twenty years, had for several months been suffering from segmental pain of thoracoabdominal or lumbosacral distribution. Diabetic radiculopathy was confirmed by paravertebral electromyography. Analgesics having brought insufficient relief, treatment with an insulin infusion pump was commenced. The pains disappeared within 2-14 days. Even when the infusion treatment was no longer used, pains did not recur under an euglycaemic regimen. These results suggest that the transitory use of insulin infusion by pump can be a worthwhile therapeutic alternative in diabetic radiculopathy.
