A 1987 questionnaire sponsored by the Health and Welfare Ministry concerning the clinical subsets and severity of systemic lupus erythematosus (SLE) was distributed to 93 medial facilities. A clinical analysis of the outcome and treatments was accomplished on one thousand six hundred and fourteen SLE patients fulfilling ARA criteria. The outcome was evaluated into 6 categories, namely; complete remission, incomplete remission, no change, gradual worsening, rapid worsening and unknown. Treatments included (1) anti-inflammatory drugs, (2) initial dose of prednisolone (PSL) below 29 mg/day, (3) initial dose of PSL from 30 to 59 mg/day, (4) initial dose of PSL above 60 mg/day, (5) pulse therapy, (6) immunosuppressants, (7) plasmapheresis, and (8) hemodialysis. Statistical significances were determined with ridit analysis. The severity of the disease for 1,614 SLE patients was evaluated by the judgement of each medical facility independently, separating it into 3 grades. As a result, 16.8% was evaluated as severe, 54.6% was evaluated as moderate, and 28.6% was evaluated as mild. Clinical subsets were divided into 3 categories according to the outcome; (1) those with high complete remission rates (serositis, convulsion, oral ulcers, unconsciousness, hemolytic anemia and so on), (2) those with high incomplete remission rates (lupus nephritis, digital gangrene, hypertension, peripheral neuropathy, erythema, Raynaud's phenomenon and so on), and (3) those with high rates of no change or worsening (aseptic bone necrosis, pulmonary hypertension, pneumonitis, chronic renal failure and so on). SLE patients with persistent proteinuria below 3.4 g/day, pulmonary hypertension, or pneumonitis treated with large doses of PSL such as an initial dose of PSL above 60 mg/day and/or pulse therapy had a significantly higher remission rate than those treated with small dosages of PSL. Hereafter, the establishment of modes of treatments for increasing the remission rates of intractable clinical subsets in highly desired.

In a survey of outpatients at the Denver Veterans Affairs Medical Center for common leg symptoms--515 questionnaires returned in a 3-week period--56% reported nocturnal leg cramps, 29% reported the restless leg syndrome, and 49% reported symptoms of peripheral neuropathy. Only 33% of patients had no symptoms relating to their legs. Patients often did not report these symptoms to their physician but were more likely to do so if the symptoms were frequent. Conditions especially related to leg symptoms were hypertension, peripheral vascular disease, coronary artery disease, cerebrovascular disease, kidney disease, and hypokalemia. Most patients did not receive effective therapy for these symptoms.

Vincristine overdose (7.5 mg/m2) was accidentally administered to 3 children with acute lymphoblastic leukemia. Treatment included double-volume exchange transfusion, phenobarbital administered prophylactically, and folinic acid rescue 18 mg every 3 hours for 16 doses. Vincristine levels were also assayed and showed a dramatic decline in postexchange levels in the 2 patients who survived and an almost unchanged value in the patient who succumbed. Early signs of toxicity in the 2 survivors were peripheral neuropathy (day 4), bone marrow toxicity (day 5), gastrointestinal toxicity (days 6 and 7), and hypertension (days 7 and 8). Marrow aplasia lasted for 4 and 10 days, peripheral neuropathy for 15 and 42 days, gastrointestinal toxicity for 3 and 5 days, and hypertension for 5 and 14 days. The 2 children were discharged on days 13 and 16 and cytostatic therapy was restarted on days 18 and 25. Both are alive without evidence of leukemia. The third patient developed liver and marrow toxicity on day 3 and died on day 9. Postmortem examination showed leukemia infiltration of the liver and spleen.

Diabetes mellitus is one of the most common medical problems in elderly patients. There is a strong rationale for therapy in most patients with diabetes, even those who are asymptomatic. Family physicians should be aware of several age-associated differences in the management and treatment of diabetes in older patients. For elderly patients, dietary modifications may include an increase in the percentage of carbohydrates and a decrease in the percentage of fat. For obese patients, dietary therapy should also emphasize a decrease in overall calories. Oral hypoglycemic agents are generally used as the initial drug therapy. Insulin therapy should be instituted when oral agents fail to reduce the blood glucose level, when the blood glucose level is very high and in other special circumstances. A careful choice of medications for other common problems associated with diabetes, such as hypertension, hyperlipidemia and peripheral neuropathy, is also essential.

An increase in the capillary permeability to albumin (CPA) has been reported in diabetic patients. We observed this frequently with a non-invasive isotopic test derived from the Landis method, using 99mTc-albumin and measuring residual radioactivity externally after removal of forearm venous compression. Evidence of the independent effects of hypertension and microangiopathy on CPA has already been found. The present work was designed to investigate CPA using the same test on diabetic patients without retinopathy and clinical proteinuria. Some of these patients had objective clinical distal and symmetrical polyneuropathy. Neuropathy was clearly present in 10 of the 11 patients with an abnormal test unexplained by causes other than diabetes and in only one of the 17 patients with a normal test. The most frequent abnormality affected the late radioactivity disappearance curve, which probably reflects an impaired lymphatic wash-out of interstitial albumin. These results strongly suggest a link between peripheral neuropathy and diabetic functional microangiopathy. An elevated blood flow secondary to sympathetic nerve failure may induce an increase in CPA and a saturation of lymphatic pumping which could also be deficient due to impaired lymphatic innervation.

The prevalence of various diabetic complications, their association with each other and with many risk factors, has been assessed in 2,337 newly diagnosed Type 2 diabetic patients. The patients entered into the UK Prospective Diabetes Study were aged between 25 and 65 (mean age 52 yr) and 33% had either an abnormal ECG or retinopathy. Different macrovascular complications such as strokes, heart attacks or abnormal ECG, and peripheral vascular disease showed little association one with another, and each was associated predominantly with different risk factors, e.g., strokes with hypertension, heart attacks with hypertriglyceridaemia and peripheral vascular disease with smoking and a low HDL cholesterol. Retinopathy was associated with reduced vibration perception but not with other complications. Reduced vibration perception and absent reflexes were associated with absent foot pulses and ischaemic skin changes, raising the possibility of a macrovascular, as well as microvascular, contribution to peripheral neuropathy. Microalbuminuria was associated with hypertension, which might be a factor predisposing to renal microvascular disease or be a consequence of it. Microalbuminuria was also associated with an abnormal ECG. Retinopathy, with exudates and or haemorrhages rather than just microaneurysms, was associated with hyperglycaemia. The occurrence of a particular complication in a diabetic patient is probably dependent on a combination of specific risk factors, many of which are related to, and probably affected by, potentially avoidable factors such as hyperglycaemia, obesity, smoking and hypertension.

Increased glycosylation of various proteins in diabetic patients has been reported by many authors. In the present study, the extent of non-enzymatic glycosylation in diabetic patients with or without chronic complications was investigated. Eighty-five diabetic patients were studied, 20 were without any clinical evidence of chronic complications while the remainder were suffering from cataract (n = 18), retinopathy (n = 16), peripheral neuropathy (n = 16) and cardiovascular complications like angina pectoris, myocardial infarction and hypertension (n = 15). All patients were selected on clinical grounds. Fifteen apparently healthy subjects of similar age and weight were studied as control subjects. Fasting plasma glucose was increased in all diabetic patients and correlated significantly with glycosylated hemoglobin, glycosylated plasma protein and serum fructosamine concentrations. There was no significant difference between diabetic patients with or without chronic complications in the levels of fasting plasma glucose, glycosylated plasma proteins, glycosylated hemoglobin, serum fructosamine, mucoprotein, hexosamine, sialic acid and fucose. Alpha-2 globulin fraction was increased in both uncomplicated and complicated diabetic patients and albumin was found to be decreased in patients with cataract, peripheral neuropathy and cardiovascular diseases. Alpha-1 and beta globulins were significantly decreased in patients with cardiovascular diseases and retinopathy respectively while gamma globulin was increased in retinopathy patients. In uncomplicated diabetic patients alpha-1 glycoprotein was decreased and gamma glycoprotein was increased. In diabetic patients with retinopathy, alpha-1 glycoprotein was elevated significantly while beta glycoprotein was decreased.

In this retrospective study, distal hyperirrigation syndrome was identified by "irrigraphy", a functional exploration method used to define an irrigation index at various levels of the lower limbs as determined by pulse wave amplitude, heart rare and segmental resistances. In 47 lower limbs studied, there were 26 unequivocal, 14 relative and 7 "masked" hyperirrigations. The main etiology was diabetes (24 limbs), but the syndrome was also noted in cases of peripheral neuropathy and chronic venous insufficiency. There was no basic difference between unequivocal and relative hyperirrigations. Some hyperirrigation states were not apparent in irrigraphy because of arterial lesions on upstream axes. The syndrome was also observed in approximately the same number of cases in insulin-dependent and noninsulin-dependent diabetes. The clinical disorders observed were especially peripheral trophic ones, notably perforating ulcers of the foot or various ulcers. Changes in the irrigraphic profile were followed regularly in 20 limbs. The rise in distal irrigation indices was due to a drop in peripheral resistances related to an abnormal opening up of arteriovenous anastomoses. A state of spontaneous sympathectomy was thus constituted, particularly in diabetic patients. The process was similar in syndromes of neurologic origin and in venous stasis. The mechanism was local, with venous hypertension causing the opening up of arteriovenous shunts. However, microangiopathic lesions must also be taken into account, since they can cause or favor arteriovenous shunting. The opening up of arteriovenous anastomoses is in effect the element common to all syndromes of distal hyperirrigation of various origins.(ABSTRACT TRUNCATED AT 250 WORDS)

Two hundred and fifty six consecutively ambulant diabetic patients attending a Nigerian diabetic clinic for the presence of cheiroarthropathy were examined using standard criteria. Forty eight (19%) had limited joint mobility of the hand, a prevalence higher than the 4% (2/56) observed in a non-diabetic population matched for age and sex. Limited joint mobility was twice as prevalent in the insulin treated (16/50, 32%) than in the non-insulin dependent (32/206, 16%) diabetics. Indices such as age, duration of diabetes, and glycaemic control (as assessed by integrated blood glucose concentration over the previous 12 months and glycated haemoglobin (HbA1c concentrations) were the same in the diabetics with and without limited joint mobility. The prevalence of cataracts (18/48, 38%) and background retinopathy (8/48, 17%) was higher in diabetics with limited joint mobility than in those without (respectively 6-9% and 5-6%); hypertension, peripheral neuropathy, and foot ulcers, however, were about equally common in the two groups of diabetics (with and without limited joint mobility). Nephropathy appeared commoner in diabetic subjects without limited joint mobility. Our results confirm previous observations in Caucasians of an increased prevalence of limited joint mobility in diabetes, especially those receiving insulin treatment, and also showed that limited joint mobility could predict the presence of retinopathy and cataracts in those diabetics. Neuropathy and hypertension were not commoner in our diabetics with limited joint mobility (unlike in the Caucasian population), suggesting that racial factors may underlie the predictive value of limited joint mobility in diabetic microangiopathy.

Long-term follow-up data on young patients receiving amiodarone is lacking, especially in relation to growth and late side effects. The records of 95 young patients (mean age 12.4 years; range 3 weeks to 31.5 years) who received amiodarone were reviewed. Minimal follow-up time for those continuing to take amiodarone was 1.5 years; the mean duration of therapy was 2.3 years (maximal 6.5). The mean maintenance dosage was 7.7 (1.5 to 25) mg/kg body weight per day. Initial success (based on symptoms and 24 h electrocardiogram) was achieved in 23 of 34 patients with ventricular tachycardia, in 32 of 33 with atrial flutter and in 21 of 28 patients with supraventricular tachycardia. However, in 7 of 33 patients with atrial flutter, the arrhythmia returned after 6 months. Patient growth continued in the same percentiles achieved before amiodarone in all but eight patients, improving in six and worsening in two with severe underlying disease. Proarrhythmia occurred in three patients: one had torsade de pointes that disappeared when amiodarone administration was stopped; two with severe anatomic heart disease died suddenly during the loading period (one with atrial flutter and one with ventricular tachycardia). Side effects occurred in 28 (29%) of the 95 patients: keratopathy (in 11), abnormal thyroid function test (in 6), chemical hepatitis (in 3), rash (in 3), peripheral neuropathy (in 2), hypertension (in 1) and vomiting (in 1). All side effects disappeared when amiodarone was discontinued or the dose was reduced.(ABSTRACT TRUNCATED AT 250 WORDS)
