- We sought to identify factors related to short-term outcome of foot ulcers in patients with diabetes treated in a multidisciplinary system until healing was achieved. Consecutively presenting patients with diabetes and worst foot ulcer (Wagner grade 1-5, below ankle) (n = 2,511) were prospectively followed and treated according to a standardised protocol until healing was achieved or until death. The number of patients lost to dropout was 31. The characteristics of the remaining 2,480 patients were: 1,465 men, age 68 +/- 15 years (range 18-96), type 1 diabetes 18%, type 2 diabetes 82% and insulin-treated 62%. The healing rate without major amputation in surviving patients was 90.6% (n = 1,867). Sixty-five per cent (n = 1,617) were healed primarily, 9% (n = 250) after minor amputation and 8% after major amputation; 17% (n = 420) died unhealed. Out of 2,060 surviving patients, 1,007 were neuroischaemic (48.8%). In a multiple regression analysis, primary healing was related to co-morbidity, duration of diabetes, extent of peripheral vascular disease and type of ulcer. In neuropathic ulcers, deep foot infection, site of ulcer and co-morbidity were related to amputation. Amputation in neuroischaemic ulcers was related to co-morbidity, peripheral vascular disease and type of ulcer. Age, sex, duration of diabetes, neuropathy, deformity and duration of ulcer or site of ulcer did not have an evident influence on probability of amputation. Patients with diabetic foot ulcer suffer from multi-organ disease. Factors related to outcome are correspondingly complex.

Forskningsöversikt (refereegranskat)abstract
- The International Working Group on the Diabetic Foot appointed an expert panel to provide evidence-based guidance on the management of osteomyelitis in the diabetic foot. Initially, the panel formulated a consensus scheme for the diagnosis of diabetic foot osteomyelitis (DFO) for research purposes, and undertook a systematic review of the evidence relating to treatment. The consensus diagnostic scheme was based on expert opinion; the systematic review was based on a search for reports of the effectiveness of treatment for DFO published prior to December 2006. The panel reached consensus on a proposed scheme that assesses the probability of DFO, based on clinical findings and the results of imaging and laboratory investigations. The literature review identified 1168 papers, 19 of which fulfilled criteria for detailed data extraction. No significant differences in outcome were associated with any particular treatment strategy. There was no evidence that surgical debridement of the infected bone is routinely necessary. Culture and sensitivity of isolates from bone biopsy may assist in selecting properly targeted antibiotic regimens, but empirical regimens should include agents active against staphylococci, administered either intravenously or orally (with a highly bioavailable agent). There are no data to support the superiority of any particular route of delivery of systemic antibiotics or to inform the optimal duration of antibiotic therapy. No available evidence supports the use of any adjunctive therapies, such as hyperbaric oxygen, granulocyte-colony stimulating factor or larvae. We have proposed a scheme for diagnosing DFO for research purposes. Data to inform treatment choices in DFO are limited and further research is, urgently needed.

Tidskriftsartikel (refereegranskat)abstract
- This article is based upon "The management of diabetic foot osteomyelitis - a progress report on diagnosing and a consensus on treating osteomyelitis". The principle of treatment is to administer antibiotics while providing a local environment in which the medication can work. This typically involves the removal of dead, soft tissue and accessible dead bone during the wound care process. These interventions may be undertaken by any appropriately trained health care provider.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND:: Heel ulcers in patients with diabetes mellitus (DM) and peripheral arterial disease (PAD) are hard to heal. The aim of the present study was to evaluate the difference in amputation-free survival (AFS) between open and endovascular revascularization in patients with DM, PAD, and heel ulcers.METHODS:: Retrospective comparative study of results of open versus endovascular surgery in patients with DM, PAD, and heel ulcer presented at the multidisciplinary diabetes foot clinic between 1983 and 2013.RESULTS:: Patients with heel ulcers were treated with endovascular intervention (n = 97) and open vascular surgery (n = 30). Kaplan-Meier analysis showed that the AFS was higher in patients undergoing open vascular surgery compared to the endovascular group ( P = .009). Multivariate analysis showed that open vascular surgery versus endovascular therapy (hazard ratio 2.1, 95% confidence interval 1.1-3.9; P = .025) was an independent factor associated with higher AFS. The proportion of patients undergoing endovascular therapy in the former (1983-2000) time period was 47% compared to 89% in the latter (2001-2013) time period ( P < .001).CONCLUSION:: The AFS was higher after open than endovascular surgery among patients with DM and PAD with heel ulcer. These results suggest that open vascular surgery should be offered more often as opposed to current practice.

Amputation for vascular disease. Prognostic factors for healing, long-term outcome and costs.
- 1997
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- General characteristics and outcome was evaluated in 177 consecutive patients who underwent a major amputation in a defined population. Smoking and diabetes lowered the mean amputation age. Healing failure at six months was seen in 24% of transtibial and in 11% of transfemoral amputees. Preoperative absence of gangrene and hemoglobin >120 g/L increased the risk of healing failure. Six months after amputation, about 1/3 used a prosthesis, 1/3 were confined to bed or a wheelchair and 1/3 had died. We analyzed all surgical procedures, total hospital stay and hospital costs in 321 consecutive patients having surgery for critical leg ischemia until at least 6-years postoperatively or until death. The first recorded operation during the inclusion year was a vascular procedure in 2/3 of all patients and a major amputation in 1/3. One third of those undergoing a reconstructive vascular procedure and half of those having a restorative vascular procedure eventually underwent an ipsilateral major amputation. The mean total long-term hospital costs were high (47,000 USD/patient), because of the need for repeated surgery (mean=3 procedures) and long hospital stay (mean=117 days). Thirty-two consecutive patients who underwent a transtibial amputation were subjected to nutritional assessment and given supplementary nutrition for 11 days. Twenty-eight patients were classified as malnourished (88%). Supplementary nutrition improved wound healing in patients with transtibial amputation, compared to a matched control group. All diabetic patients with a deep foot infection (n=223) were included consecutively during 10 years, and prospectively followed until healing for at least six months or until death. Multi-disciplinary treatment resulted in a low major amputation rate, but almost all patients needed local surgery. Duration of diabetes <14 years, a palpable popliteal pulse, a toe blood pressure >45 and an ankle blood pressure >80 mmHg, absence of exposed bone and a white blood cell count <12x109/L were all related to healing without amputation.

Tidskriftsartikel (refereegranskat)abstract
- Clinical characteristics and outcome in 223 consecutive diabetic patients with deep foot infections are reported. Patients were treated by a multidisciplinary diabetic foot-care team at the University Hospital, Lund, Sweden, and were prospectively followed until healing or death. About 50% of patients lacked clinical signs of infection, such as a body temperature > 37.8°C, a sedimentation rate > 70 mm/hour, and white blood cell count (WBC) > 10 x 109/liter. Eighty-six percent had surgery before healing or death. Thirty-nine percent healed without amputation; 34% healed after a minor and 8% after a major amputation. Sixteen percent were unhealed at death, and 3% were unhealed at the end of the observation period. Of those unhealed at death or follow-up, 4 patients had had a major and 11 a minor amputation. After correction for age and sex, duration of diabetes < 14 years, palpable popliteal pulse, a toe pressure > 45 mmHg, and an ankle pressure > 80 mm Hg, absence of exposed bone and a white blood cell count < 12 x 109/liter were all related to healing without amputation in a logistic regression analysis. We conclude that although only 1 in 10 had a major amputation, nearly all diabetic patients with a deep foot infection needed surgery and more than one third had a minor amputation before healing or death in spite of a well- functioning diabetic foot-care team responsible for all included patients.

Tidskriftsartikel (refereegranskat)abstract
- We report findings in 223 consecutively included people with diabetes, foot ulcer and a deep foot infection treated by a multidisciplinary diabetic foot care team at the University Hospital in Lund, Sweden. The aim of the present study was to evaluate type and characteristics of deep foot infections and their relation to choice of treatment and outcome. Three different groups of deep foot infections were identified; osteomyelitis only (n = 112), deep soft tissue infection only (n = 46) and combined infections (osteomyelitis and deep soft tissue infection, n = 65). The various types of deep foot infections had different characteristics, treatment and prognosis. Patients with a deep soft tissue infection only or a combined infection had a significantly (p < 0.05) higher; (1) body temperature (38.0 and 38.0 vs. 37.3°C), (2) erythrocyte sedimentation rate (75 and 80 vs. 56 mm/h) and (3) white blood count (11.0 and 12.0 vs. 8 x 109) at diagnosis compared with those who had osteomyelitis only. Patients with a deep soft tissue infection only or a combined infection also had a significantly (p < 0.05) shorter time to surgery (2 and 4 vs. 10 days), higher mean number of surgical procedures (1.9 and 2.1 vs. 1.4 procedures) and higher percentage of patients had intravenous antibiotics (87 and 84 vs. 46%) compared with those who had osteomyelitis only. Amputation before healing was more common in patients with a combined infection (62%) compared with those who had osteomyelitis only (37%) or a deep soft tissue infection only (30%). The findings in the present study indicate that deep foot infections in patients with diabetes is a heterogeneous entity, in which the type of deep foot infection is related to choice of treatment strategy and to outcome. Therefore, these various types of infections has to be considered in future studies of deep foot infections in people with diabetes. Copyright (C) 2000 Elsevier Science Inc.

Tidskriftsartikel (refereegranskat)abstract
- Protein energy malnutrition is an important determinant of clinical outcome in older patients after hip fracture, but the effectiveness of nutritional support programs in routine clinical practice is controversial. We performed a prospective, randomized, controlled clinical trial to determine if nutritional supplementation decreased fracture-related complications in a selection of otherwise healthy patients with hip fractures. Patients were randomized to intervention or control groups. The control group (n = 40) was given ordinary hospital food and beverage. The intervention group (n = 40) also was administered a 1000 kcal daily intravenous supplement for 3 days, followed by a 400 kcal oral nutritional supplement for 7 days. We recorded daily fluid and energy intake during the first 10 days of hospitalization and fracture-related complications up to 4 months. The total fluid and energy intake in the intervention group neared optimal levels. The control group received 54% and 64% of optimal energy and fluid intake, respectively. The risk of fracture-related complications was greater in the control group (70%) than in the intervention group (15%). Four patients in the control group died within 120 days postoperatively. The comprehensive balanced nutrition supplement resulted in lower complication rates and mortality at 120 days postoperatively.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Treatment of diabetic foot ulcers includes a number of different regimes such as glycaemic control, re-vascularization, surgical, local wound treatment, offloading and other non-surgical treatments. Although considered the standard of care, the scientific evidence behind the various debridements used is scarce. This presentation will focus on debridement and V.A.C. Therapy, two treatments widely used in patients with diabetes and foot ulcers. METHODS: A review of existing literature on these treatments in diabetic foot ulcers, with focus on description of the various types of debridements used, the principles behind negative pressure wound therapy (NPWT) using the V.A.C. Therapy system and level of evidence. RESULTS: Five randomized controlled trials (RCT) of debridement were identified; three assessed the effectiveness of a hydrogel as a debridement method, one evaluated surgical debridement and one evaluated larval therapy. Pooling the three hydrogel RCTs suggested that hydrogels are significantly more effective than gauze or standard care in healing diabetic foot ulcers. Surgical debridement and larval therapy showed no significant benefit. Other debridement methods such as enzyme preparations or polysaccharide beads have not been evaluated in RCTs of people with diabetes. More than 300 articles have been published on negative pressure wound therapy, including several small RCTs and a larger multi-centre RCT of diabetic foot ulcers. Negative pressure wound therapy seems to be a safe and effective treatment for complex diabetic foot wounds, and could lead to a higher proportion of healed wounds, faster healing rates, and potentially fewer re-amputations than standard care. CONCLUSIONS: Although debridement of the ulcer is considered a prerequisite for healing of diabetic foot ulcers, the grade of evidence is quite low. This may be due to a lack of studies rather than lack of effect. Negative pressure wound therapy seems to be safe and effective in the treatment of some diabetic foot ulcers, although there is still only one well-performed trial that evaluates the effect.

Tidskriftsartikel (refereegranskat)abstract
- Background and purpose With an ageing population and an increasing incidence of diabetes, reduction of the number of diabetes-related amputations becomes increasingly difficult to achieve and maintain. There is controversy in this respect regarding the degree of success. We started a multidisciplinary treatment program for diabetic foot ulcers in 1982, and have now assessed incidence rates of amputations from 1982 through 2001. Methods In a defined population, gradually increasing from 199,000 to 234,000, all diabetes-related amputations of the lower extremity from toe to hip were recorded from January 1, 1982 to December 31, 2001, using several sources of information. Results The incidence of major amputations decreased by 0.57 from 16 (11-22) to 6.8 (6.1-7.5) per 100,000 inhabitants between the first and last 4-year period. The most substantial decrease was seen in patients aged 80 years and older. The fraction of amputations with a final level at or below the ankle (n = 240) increased from 0.23 in the first 4-year period to 0.31, 0.49, 0.47, and 0.49 in the following 4-year periods. The overall fraction of re-amputation was 0.34 in the first 4-year period and 0.27, 0.21, 0.32, and 0.21 in the following 4-year periods. The fraction of amputations in diabetic patients that were channeled through the footcare team prior to amputation increased from 0.51 in the first 4-year period to 0.83, 0.86, 0.90, and 0.90 in the following 4-year periods. Interpretation Our findings indicate that a substantial decrease in the incidence of major lower extremity amputations in diabetic patients has been achieved and maintained.

Balance in single-limb stance after surgically treated ankle fractures: a 14-month follow-up
- 2006
-
Ingår i: BMC Musculoskeletal Disorders. - : Springer Science and Business Media LLC. - 1471-2474. ; 7
-
Tidskriftsartikel (refereegranskat)abstract
- Background: The maintenance of postural control is fundamental for different types of physical activity. This can be measured by having subjects stand on one leg on a force plate. Many studies assessing standing balance have previously been carried out in patients with ankle ligament injuries but not in patients with ankle fractures. The aim of this study was to evaluate whether patients operated on because of an ankle fracture had impaired postural control compared to an uninjured age- and gender-matched control group. Methods: Fifty-four individuals (patients) operated on because of an ankle fracture were examined 14 months postoperatively. Muscle strength, ankle mobility, and single-limb stance on a force-platform were measured. Average speed of centre of pressure movements and number of movements exceeding 10 mm from the mean value of centre of pressure were registered in the frontal and sagittal planes on a force-platform. Fifty-four age- and gender-matched uninjured individuals (controls) were examined in the single-limb stance test only. The paired Student t-test was used for comparisons between patients' injured and uninjured legs and between side-matched legs within the controls. The independent Student t-test was used for comparisons between patients and controls. The Chi-square test, and when applicable, Fisher's exact test were used for comparisons between groups. Multiple logistic regression was performed to identify factors associated with belonging to the group unable to complete the single-limb stance test on the force-platform. Results: Fourteen of the 54 patients (26%) did not manage to complete the single-limb stance test on the force-platform, whereas all controls managed this (p < 0.001). Age over 45 years was the only factor significantly associated with not managing the test. When not adjusted for age, decreased strength in the ankle plantar flexors and dorsiflexors was significantly associated with not managing the test. In the 40 patients who managed to complete the single-limb stance test no differences were found between the results of patients' injured leg and the side-matched leg of the controls regarding average speed and the number of centre of pressure movements. Conclusion: One in four patients operated on because of an ankle fracture had impaired postural control compared to an age- and gender-matched control group. Age over 45 years and decreased strength in the ankle plantar flexors and dorsiflexors were found to be associated with decreased balance performance. Further, longitudinal studies are required to evaluate whether muscle and balance training in the rehabilitation phase may improve postural control.

Ingår i: BMC Musculoskeletal Disorders. - : Springer Science and Business Media LLC. - 1471-2474. ; 10
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Despite conflicting results after surgically treated ankle fractures few studies have evaluated the effects of different types of training programs performed after plaster removal. The aim of this study was to evaluate the effects of a 12-week standardised but individually suited training program ( training group) versus usual care ( control group) after plaster removal in adults with surgically treated ankle fractures. Methods: In total, 110 men and women, 18-64 years of age, with surgically treated ankle fracture were included and randomised to either a 12-week training program or to a control group. Six and twelve months after the injury the subjects were examined by the same physiotherapist who was blinded to the treatment group. The main outcome measure was the Olerud-Molander Ankle Score (OMAS) which rates symptoms and subjectively scored function. Secondary outcome measures were: quality of life (SF-36), timed walking tests, ankle mobility tests, muscle strength tests and radiological status. Results: 52 patients were randomised to the training group and 58 to the control group. Five patients dropped out before the six-month follow-up resulting in 50 patients in the training group and 55 in the control group. Nine patients dropped out between the six- and twelve-month follow-up resulting in 48 patients in both groups. When analysing the results in a mixed model analysis on repeated measures including interaction between age-group and treatment effect the training group demonstrated significantly improved results compared to the control group in subjects younger than 40 years of age regarding OMAS (p = 0.028), muscle strength in the plantar flexors ( p = 0.029) and dorsiflexors ( p = 0.030). Conclusion: The results of this study suggest that when adjusting for interaction between age-group and treatment effect the training model employed in this study was superior to usual care in patients under the age of 40. However, as only three out of nine outcome measures showed a difference, the beneficial effect from an additional standardised individually suited training program can be expected to be limited. There is need for further studies to elucidate how a training program should be designed to increase and optimise function in patients middle-aged or older.

- Background Despite high incidence of ankle fractures in the elderly, studies evaluating outcome and impact of quality of life in this age group specifically are sparse. The aim of this study was to evaluate outcome and quality of life 6 and 12 months after injury in patients 65 years or older who had been operated on due to an ankle fracture. Methods Sixty patients 65 years or older were invited to participate in the study. 6 and 12 months after the injury a questionnaire including inquiry to participate, the Olerud-Molander Ankle Score (OMAS), Short-Form 36 (SF-36), Linear Analogue Scale (LAS), Self-rated Ankle Function and some supplementary questions was sent home to the patients. The supplementary questions concerned subjective experience of ankle instability, sporting and physical activity level before injury and recaptured activity level at follow-ups, need of walking aid before injury, state of living before injury and at follow-ups and co-morbidities. After the 12-month follow-up the patients were also called for a radiological examination. Results Fifty patients (83%) answered the questionnaire at 6-month and 46 (77%) at the 12-month follow-up. Although, 45 (90%) fractures were low-energy trauma 44 (88%) were bi- or trimalleolar and post-operative reduction results were complete in 23 (46%) ankles. The median OMAS improved from 60 (Interquartile range (IQR) 36) at 6-month to 70 (IQR 35) at 12-month (p = 0.002), but at 12-month still sixty percent or more of the patients reported pain, swelling, problems when stair-climbing and reduced activities of daily life. Twenty (40%) rated their ankle function as 'good' or 'very good' at 6-month and 30 (60%) at 12-month. Forty-one (82%) were physically active before injury but still one year after only 18/41 had returned to their pre-injury physical activity level. According to SF-36 four dimensions differed from the age- and gender matched normative data of the Swedish population, 'physical function', 'role physical' and 'role emotional' were below norms at 6-month for women (p = 0.010, p = 0.024 and 0.031) and 'general health' was above norms at 12-month for men (p = 0.044). Conclusion One year after surgically treated ankle fractures a majority of patients continue to have symptoms and reported functional limitations. However, SF-36 scores indicate that only females had functional status below the age- and gender matched normative data of the Swedish population.

Tidskriftsartikel (refereegranskat)abstract
- Background: The aim of this study was to evaluate the test-retest reliability and the validity of the self-reported questionnaire Olerud-Molander Ankle Score (OMAS) in subjects after an ankle fracture. Methods: When evaluating the test-retest reliability of the OMAS, 42 subjects surgically treated due to an ankle fracture participated 12 months after injury. OMAS was completed by the patients on two occasions at one to two weeks' interval. Concurrent criterion validity was evaluated using the five subscales of the Foot and Ankle Outcome Score (FAOS) and global self-rating function (GSRF), which is a five-grade Likert scale with the alternatives: "very good", "good", "fair", "poor", "very poor". Forty-six patients participated in the validation against FAOS, and for GSRF 105 patients participated at 6 months and 99 at 12 months. Uni-, bi- and trimalleolar fractures were all included and both non-rigid and rigid surgical techniques were used. All fractures healed without complications. Before analysis of the results the five groups according to GSRF were reduced to three: "good", "fair" and "poor". Test-retest reliability was assessed using Spearman's rank correlation, the intraclass correlation coefficient (ICC), the standard error of measurement (SEM and SEM%) and the smallest real difference (SRD and SRD%). The Cronbach's alpha score and validity versus FAOS was assessed using Spearman's rank correlation and validity versus GSRF using the Kruskal-Wallis Test and the Mann-Whitney U-Test as ad hoc analyses. Results: The test-retest reliability correlation coefficient obtained was rho = 0.95 and ICC = 0.94. The SEM was 4.4 points and SEM% 5.8% and should be interpreted as the smallest change that indicates a real change of clinical interest for a group of subjects. The SRD was 12 points and SRD% 15.8% and should be interpreted as the smallest change that indicates a real change of clinical interest for a single subject. The correlation coefficients versus the five subscales of FAOS ranged from rho = 0.80 to 0.86. There were significant differences between GSRF groups "good", "fair" and "poor" (p < 0.001) at both the six-month and the 12-month follow-up. The internal consistency for the OMAS was 0.76. The effect size between results from 6-month and 12-month follow-up turned out be 0.44 and should be considered as medium. Conclusion: The results showed that the test-retest reliability of the Swedish version of OMAS was very high in subjects after an ankle fracture and the standard error of measurement was low. Furthermore the OMAS was found to be valid using both the five subscales of FAOS and the GSRF. The OMAS can thus be used as an outcome measure after an ankle fracture.

- The aim of this study was to evaluate outcome after surgical intervention in patients with ankle fractures. Fifty-four patients consecutively operated were included. A standardised protocol was used to record a number of variables regarding patient characteristics, type of fracture and treatment. Radiographic examination was performed in all patients postoperatively and after 14 months. A questionnaire containing the Olerud–Molander Ankle Score (OMAS) and some supplementary questions was used 14 months and 3 years after surgery. The median OMAS was 75 at the 14-month and 85 at the 3-year follow-up. Patients <40 years of age scored significantly better. Only 50% returned to the same activity level 14 months after injury. Pain, stiffness and swelling were present among more than half of the patients and 40% reported instability and problems when using stairs. In conclusion, subjective outcome 3 years after surgical intervention for ankle fractures is poorer than expected.

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Novel NS3/4A protease inhibitors comprising quinazoline derivatives as P2 substituent were synthesized. High potency inhibitors displaying advantageous PK properties have been obtained through the optimization of quinazoline P2 substituents in three series of macrocyclic P2 cyclopentane dicarboxylic acid and P2 proline urea motifs. For the quinazoline moiety it was found that 8-methyl substitution for the P2 cyclopentane dicarboxylic acid series improved on the stability in human liver microsomes. By comparison, the proline urea series displayed advantageous Caco-2 permeability over the cyclopentane series. properties were assessed in rat on selected compounds. Excellent exposure and liver–to-plasma ratios were demonstrated for a member of the 14-membered quinazoline substituted P2 proline urea series. In vivo pharmacokinetic properties were assessed in rat on selected compounds. Excellent exposure and liver–to-plasma ratios were demonstrated for a member of the 14-membered quinazoline substituted P2 proline urea series.

Raised serum S100B levels after acute bone fractures without cerebral injury
- 2005

- Background: S100B, a protein abundant in astroglial cells within the central nervous system, has been shown to increase in cerebrospinal fluid and serum after various neurologic diseases. However, the cerebral specificity of S100B has been questioned. This study aims to show serum S100B levels after uncomplicated bone fractures in patients without current or prior neurologic diseases. Methods: Blood for sampling was drawn from patients seeking care at the emergency department presenting with various uncomplicated orthopedic fractures no older than 24 hours and having no previous or suspected neurologic disorder or head injury. Results: Fifty-five consecutive patients with acute fractures were included in the study. Serum S100B levels were raised above 0.15 mug/L in 16 of 55 (29%) patients (range, 0.02-0.51 mug/L; mean, 0.13 +/- 0.11 mug/L). Conclusion: S100B levels were raised in 29% of patients with acute fractures without apparent cerebral injury, which suggests an extracerebral source of S100B. This information should be taken into account when interpreting S100B levels when dealing with brain damage.

- A heel ulcer is considered to be a serious complication in patients with diabetes, and there is limited information regarding outcome. In most of the literature, a poor prognosis is described. The aim of this study was to investigate a large cohort of ulcers located in the heel in patients with diabetes. Seven hundred and sixty-eight patients [median age 73 (17-98)], presenting with a heel ulcer at a multidisciplinary diabetes foot clinic, fulfilled the inclusion criteria and were followed-up until final outcome. Fifty-eight per cent of the patients healed primarily; 7% healed after major debridement; 9% healed after amputation and 25% died unhealed. Median healing time was 17 weeks. Ulcer progression was seen in 19% of patients. Thirty-one percent of patients had severe peripheral vascular disease. A creatinine level below 91 μmol/l was related to a higher probability for healing without major debridement or amputation, whereas vascular surgery, nephropathy and oedema were related to a lower probability for healing without major debridement or amputation. Two thirds of heel ulcers do heal in patients with diabetes despite patients being elderly and with extensive comorbidity. The extent of peripheral vascular disease, nephropathy, oedema and decreased renal function are important factors influencing outcome.

- Diabetic foot ulcer is an important entity which in many cases is the first serious complication in diabetes. Although a plantar forefoot location is common, there are few studies on larger cohorts and in such studies there is often a combination of various types of ulcer and ulcer locations. The purpose of this study is to discern the outcome of plantar forefoot ulcers and their specific characteristics in a large cohort. All patients (n=770), presenting with a plantar forefoot ulcer at a multidisciplinary diabetes foot clinic from January 1(st) 1983 to December 31(st) 2012 were considered for the study. 701 patients (median age 67 (22-95) fulfilled the inclusion criteria and were followed according to a pre-set protocol until final outcome (healing or death). Severe peripheral vascular disease (SPVD) was present in 26% of the patients and 14% had evidence of deep infection upon arrival at the foot clinic. Fifty-five per cent (385/701) of the patients healed without foot surgery, 25% (173/701) healed after major debridement, nine per cent (60/701) healed after minor or major amputation and 12% (83/701) died unhealed. Median healing time was 17 weeks. An ulcer classified as Wagner grade 1 or 2 at inclusion and independent living were factors associated with a higher healing rate. Seventy-nine per cent of 701 patients with diabetes and a plantar forefoot ulcer treated at a multidisciplinary diabetes foot clinic healed without amputation. For one third some form of foot surgery was needed to achieve healing. This article is protected by copyright. All rights reserved.

- OBJECTIVE: To analyse the outcome of minor amputations (through, or distal to, the ankle joint) in patients with diabetes. METHOD: All diabetic patients in a defined population undergoing one or more minor amputation between 1982 and 2006 were investigated according to a standardised protocol and were followed until final outcome (healing or death). A total of 410 consecutive amputations in 309 patients with a median age of 73 (32-93) years were identified. RESULTS: In 94% of amputations, deep infection (39%) and/or gangrene (55%) was present. Severe peripheral vascular disease or critical limb ischaemia was present in 61% of amputations. 261/410 (64%) of the amputations healed at a level below the ankle joint; 69/410 (17%) healed after a re-amputation above the ankle joint; in 76/410 of amputations (19%), the patient died before healing could occur. In surviving patients, 79% of the amputations healed below the ankle. Median healing time for amputations that healed below the ankle was 26 (2-250) weeks; 21% of amputations required a re-amputation above the ankle. None of the analysed parameters excluded the possibility of healing below the ankle. CONCLUSION: In this population-based survey, the goal of avoiding major amputation was achieved in almost two thirds of minor amputations, but at the price of long healing times. In almost all amputations, the patient had deep infection and/or gangrene. In spite of this, 64% of all amputations, and 79% of amputations in surviving patients, healed at a level below the ankle. This indicates that minor amputations in these patients are worthwhile. DECLARATION OF INTEREST: None

- Diabetic foot ulcer is a serious complication in patients with diabetes. In most outcome studies of this condition, there is a combination of various types of ulcer and ulcer locations. Plantar ulcers are usually localized to the forefoot, and constitute a quarter of all diabetic foot ulcers. There are a limited number of studies regarding development of new ulcers following healing of a plantar forefoot ulcer, and there are no uniform definitions of recurrent and other new ulcers. The aim of this study was to evaluate the outcome of a large cohort of consecutively treated patients with diabetes mellitus and a healed planter forefoot ulcer (n = 617) with regard to development, characteristics, and outcome of recurrent and other new ulcers. Patients were followed consecutively and prospectively with a 2-year follow-up, according to a preset protocol. Out of 617 patients, 250 (41%) did not develop any new ulcer, 262 (42%) developed a new ulcer, 87 (14%) died and 18 (3%) were lost at 2 years following healing of a plantar forefoot ulcer. Thirty-four percent developed other new ulcers (112 on the same foot and 99 on the contralateral foot), whereas 51 patients (8%) developed a recurrent ulcer (at the same site and foot). Of the patients who died within 2 years, 30 patients had developed other new ulcers. The risk of a recurrent ulcer in patients with diabetes and a healed plantar forefoot ulcer was only 8% within 2 years, whereas other new ulcers, on the same foot or on the contralateral foot, was seen in 4 out of 10 patients indicating the need for further preventive measures and surveillance in these patients. We suggest a concise definition for new ulcer to be used in future research.
