This randomized, double-blind study investigated the effect of ciprostene, a stable epoprostenol (prostacyclin) analog in patients with peripheral vascular disease (PVD) characterized by ischemic ulcers. A total of 211 patients (106 ciprostene, 105 placebo) received IV infusions of ciprostene (120 ng/kg/min in 8-hour daily infusions for 7 days) or placebo. The two groups were comparable with regard to demographic data. Only 45% of the patients receiving ciprostene and 55% of the placebo patients completed the trial. The groups were similar in frequency of amputations, vascular surgery, and development of new ulcers. Among those who completed the trials an insignificantly higher percentage of patients receiving ciprostene had all ulcers heal completely. The reduction of ulcer size by at least 50% was higher in the ciprostene-treated group at month 4 (P = .005). Both ciprostene and placebo reduced the severity of a patient's rest pain. There was no difference in the ankle brachial index between the groups. Ciprostene induced a higher incidence of headache, nausea, and flushing during infusion when compared with the placebo group. The results confirmed inherent problems with studies in PVD, namely, scarcity of patients with ischemic ulcers, inclusion of severely ill patients leading to a high dropout rate, and a high placebo effect. Good tolerance and safety of ciprostene was documented in this patient population, and the therapeutic benefit was limited to partial reduction of ulcer size. Selection of patients with less advanced disease and a longer infusion of ciprostene may improve the clinical benefit of this agent.

An elderly man with ischaemic heart and peripheral vascular disease presented with a 3-month history of increasingly severe postprandial epigastric pain, nausea, vomiting, diarrhoea and weight loss, associated with gastroscopic evidence of superficial antral ulceration and discoloration. The patient died shortly after admission to hospital. Autopsy showed evidence of mesenteric vascular disease and ischaemic bowel. The literature on chronic mesenteric ischaemia is briefly reviewed, and the role of arteriography is discussed.

In a double-blind randomized trial, imipenem/cilastatin (I/C; 500 mg every 6 hours) and ampicillin/sulbactam (A/S; 3 g every 6 hours) were compared in regard to their efficacy for initial empirical and definitive parenteral treatment of limb-threatening pedal infection in diabetic patients. The major endpoints of treatment were cure (resolution of soft-tissue infection), failure (inadequate improvement, necessitating a change in antibiotic therapy), and eradication (clearance of all pathogens from the wound and any bone cultures). Patients in the two treatment groups were similar in regard to the severity of diabetes; presence of neuropathy and peripheral vascular disease; site and severity of infection; pathogen isolated; and frequency of osteomyelitis (associated with 68% of the 48 A/S-treated infections and 56% of the 48 I/C-treated infections). After 5 days of empirical treatment, improvement was noted in 94% of the A/S and 98% of the I/C recipients. At the end of definitive treatment (days' duration [mean +/- SD]: 13 +/- 6.5 [A/S], 14.8 +/- 8.6 [I/C]), outcomes were similar: cure, 81% (A/S) vs. 85% (I/C); failure, 17% (A/S) vs. 13% (I/C); and eradication, 67% (A/S) vs. 75% (I/C). Treatment failures were associated with the presence of antibiotic-resistant pathogens and possible nosocomial acquisition of infections. The number of adverse events among patients in the two treatment groups was similar: 7 in the A/S group (4 had diarrhea and 3 had rash) and 9 in the I/C group (5 had diarrhea, 2 had severe nausea, 1 had rash, and 1 had seizure). Efficacy of A/S and I/C is similar for initial empirical and definitive treatment of limb-threatening pedal infection in patients with diabetes.

Metformin is an oral antihyperglycemic agent that is approved by the Food and Drug Administration for the treatment of noninsulin-dependent diabetes mellitus. It differs from the sulfonylureas in that it is does not enhance insulin secretion and normally does not produce hypoglycemia. Metformin acts to decrease preprandial and postprandial blood glucose concentrations by increasing skeletal muscle uptake of glucose, decreasing gluconeogenesis, and decreasing absorption of glucose. The addition of metformin to maximum dosages of a sulfonylurea may synergistically improve glucose control. The drug may offer other potential benefits, such as weight loss or minimal weight gain, improved blood flow in patients with peripheral vascular disease, reduction of tissue plasminogen activator inhibitor, and improved lipid profiles. It is relatively safe if taken appropriately. Its most common side effects are gastrointestinal (nausea, diarrhea, anorexia), metallic taste, and vitamin B12 malabsorption. Lactic acidosis may also occur, but it is rare if metformin is avoided in patients with contraindications to its use. With careful monitoring, the agent may be considered for the initial treatment of obese patients who fail dietary measures, and those whose disease is refractory to maximum dosages of sulfonylureas or who do not tolerate them.

Elevated blood pressure is a risk factor for a variety of cardiovascular disorders, including coronary heart disease, peripheral vascular disease, cardiac failure and cerebrovascular disease. The prevailing view is that an elevated systolic rather than diastolic blood pressure is the major contributor in mortality and morbidity attributed to cardiovascular disorders. Isolated high systolic blood pressure, especially in the elderly, is a major risk factor and should undoubtedly be a target for drug treatment. In the general population, systolic and diastolic blood pressure are highly correlated, and thus it is difficult to dissociate the effects of these two components of the blood pressure and specifically ascribe cardiovascular risk factors to just elevated systolic blood pressure. Therefore, the goal in therapy of an individual with hypertension must be to reduce elevated systolic and diastolic blood pressure in order to reduce mortality and morbidity. ACE and neutral peptidase inhibitors are a new class of drugs that may be beneficial in the treatment of patients with hypertension and heart failure. They may also be useful in the treatment of diabetic patients with hypertension and/or heart failure. Drugs of this class are dual inhibitors of ACE and neutral endopeptidase, and are capable of affecting vascular tone and fluid balance. They are capable of producing vasodilatation by virtue of inhibiting the production of angiotensin II, degradation of natriuretic peptides and bradykinin. They also appear to promote natriuresis and diuresis by amplifying the actions of natriuretic peptidase and reducing aldosterone effects. In addition, they should also attenuate trophogenic actions of the renin angiotensin system and the sympathetic nervous system. Omapatrilat is one drug that appears to be at the advanced stages of clinical development. This drug has been shown to be quite effective in the treatment of hypertension. Evidence also seems to indicate that treatment with omapatrilat results in a higher tendency towards preventing death and worsening heart failure when compared with treatment with a pure ACE inhibitor in patients with advanced heart failure. Overall safety with omapatrilat appears to be good, but like other ACE inhibitors the incidence of cough is higher when compared with placebo. Other common adverse effects noted are headaches, facial flushing/warm sensation, dizziness, nausea and dyspnoea. Of greater concern is the occurrence of angio-oedema, the true incidence of which remains to be fully established as part of the published medical literature.

Ergotamine is used to abort or prevent migraine. The most common adverse reactions are nausea, vomiting, myalgia, diarrhea or mouth dryness, and the contraindications are peripheral vascular disease because of its vasospastic effect, and liver disease because the drug is metabolized in this organ. Its effects on the heart are less frequent and less well known. We report two patients on long-term ergotamine treatment who developed valvular disorders.

Caudal block with a local anesthetic through the hiatus sacralis has been performed in patients with chronic low back pain, lower limb pain, anal pain, and pelvic pain due to spinal canal stenosis, lumbar disc herniation, lumbar spondylolisthesis, postherpetic neuralgia, peripheral vascular disease, complex regional pain syndrome and so on. We prepar- ed an information and consent sheet on caudal block in The University of Tokyo Hospital. In the information sheet, we included disease, purpose, methods, outcome, accidental complications of caudal block, other treatments, progress on unperformed case, questions and answers, influence of rejection, and doctor's name. We experienced some cases of boring pain, deterioration of low back pain and lower limb pain, headache, nausea, hypertension, hypotension, and tachycardia as accidental complications of caudal block. In describing some accidental complications, we included boring pain, high intracranial pressure, dural puncture, nerve injury, infection, hemorrhage, embolism, allergy, and heart, lung, brain, liver, and kidney failures. Further, we could refer to the accidental complications of epidural block. However, the rate of each accidental complication has not been known in detail. We should survey the outcome and accidental complication of caudal block prospectively in multiple facilities and provide the patients with useful information.

The prevalence of onychomycosis is nearly 20% in patients aged >60 years. In North America, 90% of toenail onychomycosis is caused by dermatophytes (Trichophyton species). Distal-lateral subungual onychomycosis is the most common clinical presentation. The potassium hydroxide test is the most cost-effective diagnostic method. Although nail clipping for histology using periodic acid-Schiff stain is more sensitive, it is much more expensive. Elderly patients have specific risk factors for poor response to therapy for onychomycosis, including frequent nail dystrophy, slow growth of nails and increased prevalence of peripheral vascular disease and diabetes mellitus. Elderly people with diabetes should be treated for onychomycosis to prevent secondary bacterial infections and subsequent complications. Terbinafine is the drug of choice for dermatophyte onychomycosis, with greater mycological cure rates, less serious and fewer drug interactions, and a lower cost than continuous itraconazole therapy. Adjunct debridement may improve the clinical and complete cure rates compared with terbinafine alone. Common adverse effects of terbinafine in the elderly include nausea, sinusitis, arthralgia and hypercholesterolaemia. For onychomycosis caused by Candida or nondermatophyte moulds, there is no superior systemic therapy. In general, topical nail lacquers, amorolfine and ciclopirox are not practical for elderly patients because of the recommended frequency of application, periodic routine debridement of affected nails and long duration of therapy. However, nail lacquers may be a good option as monotherapy for patients with superficial white onychomycosis or in combination with systemic antifungal therapy for patients with predisposing factors for poor response or recurrence.

Sulodexide is a highly purified glycosaminoglycan containing a combination of heparan sulfate with affinity for antithrombin III and dermatan sulfate with affinity for heparin cofactor II. This antithrombotic and antithrombin activity is of great pharmacologic interest and makes sulodexide a suitable drug for the prophylaxis and treatment of arterial and venous peripheral diseases. In arterial pathology, changes in the Winsor Index, improvement in peripheral blood flow, and reduction in pain-free walking distance confirm that treatment with oral sulodexide is effective. Lipid components linked to the genesis of peripheral vascular processes, including triglycerides, total cholesterol, and low-density lipoprotein fractions, as well as plasma and blood viscosity, are reduced by the administration of sulodexide, whereas the high-density lipoprotein fraction increases. Sulodexide inhibits aggregation and adhesion of platelets at the level of the vascular wall, reduces plasma fibrinogen concentrations, reduces plasminogen activator inhibitor-1, and increases tissue plasminogen activator, as well as systemic fibrinolytic and thrombolytic activity, thereby demonstrating efficacy in the treatment of thromboembolic disease. There is no interaction between sulodexide and other drugs used as long-term treatment for peripheral vascular disease. It is well tolerated, and the adverse reactions described after oral administration are related mainly to transient gastrointestinal intolerance, ie, nausea, dyspepsia, and minor bowel symptoms. Sulodexide may become the treatment of choice when dealing with vascular diseases and their complications, as well as for the prevention of venous thromboembolic disease, being particularly indicated in elderly patients, due to its good tolerability and ease of management.

Clopidogrel is an oral antiplatelet agent used in the treatment of coronary artery disease, peripheral vascular disease and cerebrovascular disease. Gastrointestinal symptoms including nausea, diarrhea and constipation are the common side effects of this drug. Serious side effects like intracranial hemorrhage and severe neutropenia were also reported but spontaneous pectoral hematoma due to the clopidogrel has not been reported previously. We present a case of large spontaneous pectoral hematoma during clopidogrel therapy in an elderly woman.
