Plantar pressures in diabetic patients with foot ulcers which have remained healed

DIABETIC MEDICINE, Issue 11 2009
T. M. Owings
Abstract Aims, The recurrence of foot ulcers is a significant problem in people with diabetic neuropathy. The purpose of this study was to measure in-shoe plantar pressures and other characteristics in a group of neuropathic patients with diabetes who had prior foot ulcers which had remained healed. Methods, This was an epidemiological cohort study of patients from diabetes clinics of two Swedish hospitals. From a database of 2625 eligible patients, 190 surviving patients with prior plantar ulcers of the forefoot (hallux or metatarsal heads) caused by repetitive stress were identified and 49 patients agreed to participate. Barefoot and in-shoe plantar pressures were measured during walking. Data on foot deformity, activity profiles and self-reported behaviour were also collected. Results, Mean barefoot plantar peak pressure at the prior ulcer site (556 kPa) was lower than in other published series, although the range was large (107,1192 kPa). Mean in-shoe peak pressure at this location averaged 207 kPa when measured with an insole sensor. Barefoot peak pressure only predicted ,35% of the variance of in-shoe peak pressure, indicating variation in the efficacy of the individual footwear prescriptions (primarily extra-depth shoes with custom insoles). Conclusions, We propose that the mean value for in-shoe pressures reported in these patients be used as a target in footwear prescription for patients with prior ulcers. Although plantar pressure is only one factor in a multifaceted strategy to prevent ulcer recurrence, the quantitative focus on pressure reduction in footwear is likely to have beneficial effects.

ABSTRACT Objective., Although curative treatment of Helicobacter pylori infection markedly reduces the relapse of peptic ulcers, the details of the ulcers that do recur is not well characterized. The aim of this study is to describe the recurrence rate and specific features of peptic ulcers after cure of H. pylori infection. Methods., This was a multicenter study involving 4940 peptic ulcer patients who were H. pylori negative after successful eradication treatment and were followed for up to 48 months. The annual incidence of ulcer relapse in H. pylori -cured patients, background of patients with relapsed ulcers, time to relapse, ulcer size, and site of relapsed ulcers were investigated. Results., Crude peptic ulcer recurrence rate was 3.02% (149/4940). The annual recurrence rates of gastric, duodenal and gastroduodenal ulcer were 2.3%, 1.6%, and 1.6%, respectively. Exclusion of patients who took NSAIDs led annual recurrence rates to 1.9%, 1.5% and 1.3%, respectively. The recurrence rate was significantly higher in gastric ulcer. Recurrence rates of patients who smoked, consumed alcohol, and used NSAIDs were significantly higher in those with gastric ulcer recurrence compared to duodenal ulcer recurrence (e.g. 125 of 149 [83.9%] relapsed ulcers recurred at the same or adjacent sites as the previous ulcers). Conclusions., Curative treatment of H. pylori infection is useful in preventing ulcer recurrence. Gastric ulcer is more likely to relapse than duodenal ulcer. Recurrent ulcer tended to recur at the site of the original ulcers. [source]


Maintenance therapy with H2 -receptor antagonist until assessment of Helicobacter pylori eradication can reduce recurrence of peptic ulcer after successful eradication of the organism: prospective randomized controlled trial

KAZUNARI MURAKAMI
Abstract Purpose:, This study examined the possible relationship between peptic ulcer recurrence and the presence or absence of maintenance therapy with an H2 -receptor antagonist performed until evaluation of Helicobacter pylori eradication. Methods:, The subjects were 483 patients with peptic ulcer (281 gastric ulcer and 202 duodenal ulcer) who were diagnosed as H. pylori positive. After receiving eradication therapy for H. pylori, patients were allocated at random to one of three different maintenance therapies: control group (no maintenance therapy), H2 -receptor antagonist half-dose group, and H2 -receptor antagonist full-dose group. The maintenance therapy was performed for 4 weeks until evaluation of H. pylori eradication. Results:, Among the 25 patients with a recurrent ulcer, 18 patients (72%) had a recurrence at the time of or before evaluation of H. pylori eradication. In the control group, the rate of ulcer recurrence occurring before evaluation of H. pylori eradication was 10.5% (14/133). This rate was significantly higher than those in the H2 -receptor antagonist half-dose group (2.9%, 4/136) and the full-dose group (0%, 0/135). Conclusion:, The results of this study suggest that maintenance therapy with an H2 -receptor antagonist performed after eradication therapy until evaluation of H. pylori eradication is likely to greatly reduce the ulcer recurrence rate without affecting evaluation of H. pylori eradication.

Summary Background The role of Helicobacter pylori in the pathogenesis of peptic ulcer disease in patients with uraemia remains unclear. Aim To evaluate the long-term effect of H. pylori eradication in these patients. Methods Uraemic and non-uraemic patients with peptic ulcer were enrolled in this study. Patients having history of non-steroidal anti-inflammatory drugs use or cardiovascular disease that need aspirin use were excluded. After confirmation of H. pylori infection, they received a triple therapy and were followed up for 2 years. Results Between September 1999 and December 2005, 34 patients (41%) of the end-stage renal disease [H. pylori (+) group] and 67 (84%) of the non-uraemic patients with peptic ulcer disease (PU group) received anti- H. pylori therapy. After triple therapy, 32 (94%) from the end-stage renal disease group and 64 (96%) from the peptic ulcer group obtained successful eradication. During the 2-year follow-up, three patients in the end-stage renal disease group were excluded because of the presence of cardiovascular disease and aspirin use in two cases and died of heart failure in one case; two patients in peptic ulcer group refused follow-up. Finally, 29 uraemic and 62 non-uraemic patients had achieved the follow-up. Recurrence of peptic ulcer was more in the end-stage renal disease group than in the peptic ulcer group with intention-to-treat analysis (eight of 32, 25% vs. two of 64, 3%, P = 0.001, OR: 10.0, 95% CI: 1.979,50.540) or per-protocol analysis (eight of 29, 28% vs. two of 62, 3%, P < 0.001, OR: 11.4, 95% CI: 2.245,58.168). Conclusions Peptic ulcer recurrence after H. pylori eradication is higher in end-stage renal disease patients with peptic ulcer than in peptic ulcer patients without renal disease. Factors aside from H. pylori play an important role in peptic ulcer recurrence in end-stage renal disease patients. [source]


Occurrence and relapse of bleeding from duodenal ulcer: respective roles of acid secretion and Helicobacter pylori infection

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 6 2001
G. Capurso
Background: Helicobacter pylori infection, gastric acid hypersecretion and NSAID consumption may cause peptic ulcer. Aim: To investigate the respective roles of H. pylori and acid secretion in bleeding duodenal ulcer. Patients and methods: A total of 99 duodenal ulcer patients were referred for evaluation of acid secretion: seven with Zollinger,Ellison Syndrome; 14 with hypersecretory duodenal ulcer, defined by the coexistence of elevated basal acid output and pentagastrin acid output; and 78 duodenal ulcer patients with normal acid output. All non-Zollinger,Ellison Syndrome patients were H. pylori -positive and cured of infection. All patients were followed-up for a 36-month period, to assess the occurrence of bleeding episodes. Results: Twenty-nine patients had at least one bleeding episode in the 4 years before the study. Bleeding was more frequent in males and in patients on NSAIDs. The mean basal acid output was not higher among bleeders. In the 21 patients (14 hypersecretory duodenal ulcer, seven Zollinger,Ellison Syndrome) with basal acid output > 10 meg/h and pentagastrin acid output > 44.5 meg/h, the risk of bleeding was higher (OR 6.5; 95% CI: 2,21). In the follow-up period, three out of 83 (3.3%) non-Zollinger,Ellison Syndrome patients had a H. pylori -negative duodenal ulcer with bleeding. The risk of bleeding after H. pylori cure was not higher in hypersecretory duodenal ulcer patients (P > 0.3), nor among patients with previous bleeding episodes (P > 0.2). Conclusions: In H. pylori -positive duodenal ulcer patients, the coexistence of elevated basal acid output and pentagastrin acid output leads to a sixfold increase in the risk of bleeding. After H. pylori cure, gastric acid hypersecretion is not a risk factor for bleeding. However, duodenal ulcer recurrence with bleeding may occasionally occur in patients cured of H. pylori, even if acid output is normal. [source]


Reliability of free-flap coverage in diabetic foot ulcers

MICROSURGERY, Issue 2 2005
Ömer Özkan M.D.
As microsurgery advances, microsurgical free-tissue transfers have become the reconstructive method of choice over staged or primary amputation, and enabling independent ambulation in difficult lower-extremity wounds. In this report, we present our experiences with free-tissue transfer for the reconstruction of soft-tissue defects in 13 diabetic foot ulcers. Following radical debridement, soft-tissue reconstruction was achieved in the following ways: anterolateral thigh fasciocutaneous flap in 5 patients, radial forearm fasciocutaneous flap in 3 patients, lateral arm fasciocutaneous flap in 1 patient, gracilis musculocutaneous flap in 1 patient, tensor fascia latae flap in 1 patient, deep inferior epigastric perforator flap in 1 patient, and a parascapular flap in the remaining patient. In 8 cases, diabetic wounds were in the foot, while wounds were at the level of the lower leg in the remaining patients. In all patients, vascular patency was confirmed by the Doppler technique. In suspicious cases, arteriography was then performed. While all flaps survived well in the postoperative period, one patient died from cardiopulmonary problems on postoperative day 16 in an intensive care unit. Amputation was necessary in the early postoperative period because of healing problems. In the remaining 10 cases, all flaps survived intact. In one case, arterial revision was performed successfully. The ultimate limb salvage rate was 83% for the 12 patients. Independent ambulation was achieved in these cases. During the follow-up period of 8 months to 2 years, no ulcer recurrence was noted, and no revascularization or vascular bypass surgery was needed before or after the free-tissue transfers. The authors conclude that free-tissue transfer for diabetic foot ulcers is a reliable procedure, despite pessimistic opinions regarding the flap survival and low limb salvage rates. It should be considered a useful reconstructive option for serious defects in well-selected cases. © 2005 Wiley-Liss, Inc. Microsurgery 25:107,112, 2005. [source]


Investigation and treatment of chronic venous ulcer disease

ANZ JOURNAL OF SURGERY, Issue 4 2001
M. C. Stacey
Introduction: The investigation and treatment of chronic venous ulceration continues to present many difficulties for the clinician. The uncertainties relate to the appropriate use of different forms of investigation and whether conservative treatment or surgical treatment should be used. Method: A comprehensive search was undertaken of published literature on venous ulceration. Results: The extent of investigations is largely determined by the type of treatment that the patient is either fit to undertake or is prepared to undertake. When conservative treatment only is to be used, detailed investigation of the venous system is not required. The role of surgery to the veins remains unproven in improving the healing of venous ulcers. Surgery to prevent ulcer recurrence has been demonstrated to be of benefit only in patients who have normal deep veins. Conclusions: Investigations performed on the venous system should be determined by the planned treatment. Many of the operations that have been performed on the venous system still remain unproven in providing a benefit to the healing of venous ulcers and in preventing venous ulcer recurrence. [source]
