Reduction of leg wound infections following coronary artery bypass surgery.

OBJECTIVE: To reduce the rate of infection at the saphenous vein harvest site after coronary artery bypass surgery, to identify predictors of infection and to determine the best method for leg wound closure. DESIGN: A randomized clinical trial was undertaken to determine the best technique for reducing the postoperative leg wound infection rate. Patients were allocated to one of four leg wound closure methods: staples, close immediately; staples, close after protamine administration; subcuticular sutures, close immediately; and subcuticular sutures, close after protamine. Risk factors evaluated were age, sex, diabetes, obesity, peripheral vascular disease, reoperation, time in surgery, wound length, wound depth, time that the wound was open, wound quality and harvest site. SETTING: The Walter C Mackenzie Health Sciences Centre, University of Alberta, Edmonton, Alberta. PATIENTS: All consenting patients undergoing elective coronary artery bypass surgery involving saphenous vein harvesting were considered for the study. Exclusion criteria were insertion of a drain, insertion of an intra-aortic balloon pump in the index limb and inability to complete follow-up at the authors' centre. Eighty patients were initially enrolled, with 77 completing the study. INTERVENTIONS: Patients underwent standard saphenous vein harvesting followed by wound closure as indicated by the study group. MAIN RESULTS: The major infection rate was reduced from 13% to 3% (P = 0.02). Each closure method was equally effective, and wound depth was the only factor related to infection. CONCLUSIONS: Leg wound infections continue to be a major source of morbidity after coronary bypass surgery.

Venous dynamics in leg lymphedema.

To determine whether there is anatomical and/or functional impairment to venous return in patients with lymphedema, we examined venous dynamics in 41 patients with unilateral leg lymphedema. A Volometer was used for computer analysis of leg volume, a color Duplex Doppler scanner was used to determine deep vein patency and skin thickness, and Air-plethysmography was used to assess ambulatory venous pressure, venous volume, venous filling index and the ejection fraction. In the lymphedematous leg, volume and skin thickness were uniformly increased (126.4 +/- 21.3% and 156.9 +/- 44.5%) (mean +/- S.D.), respectively. The ambulatory venous pressure was also increased (134 +/- 60.7%) as was the venous volume (124.5 +/- 37.5%), and the venous filling index (134.5 +/- 50.5%). The ejection fraction was decreased (94.9 +/- 26.1%). Greater leg volume correlated with increased venous volume and venous filling index (values = 0.327, 0.241, respectively) and decreased ejection fraction (r = -0.133). Increased subcutaneous thickness correlated with increased venous filling index and venous volume (r = 0.307, 0.126, respectively) and decreased ejection fraction (r = -0.202). These findings suggest that soft tissue edema from lymphatic stasis gradually impedes venous return which in turn aggravates the underlying lymphedema.

Atherosclerosis in amputated legs of patients with and without diabetes mellitus.

BACKGROUND: The aim of this study was to compare the histomorphologic appearance of atherosclerosis in amputated legs of diabetic and non-diabetic patients. METHODS: Twenty-eight legs amputated below the knee for chronic ischaemia were studied. Fourteen legs were amputated in patients with diabetes (10 Type II, 4 nonclassified) and 14 in non-diabetics. The mean age of patients at the time of the amputation was 63.3 years in diabetics and 63.9 years in non-diabetics. Samples were taken from the main arteries at the following levels: the midleg, 5 cm above the ankle, 3 cm below the ankle and 10 cm below the ankle. Cross-sections of the arteries were examined with light microscopy and the severity of the occlusive disease determined using morphometric analysis. Medial calcification and chronic inflammation were assessed semiquantitatively. RESULTS: Arteries at 5 cm above the ankle were more severely stenotic in diabetics than in non-diabetics (p<0.05). In both diabetics and non-diabetics the posterior tibial and plantar arteries appeared to be the most stenotic. Medial calcification tended to be more prominent in diabetics than in non-diabetics. Chronic inflammation in the arterial wall occurred at the same degree in diabetics and non-diabetics. In non-diabetics chronic inflammation was more severe in the posterior tibial and plantar arteries than in the anterior tibial and dorsalis pedis arteries (p<0.04). Chronic arterial inflammation correlated with the severity of chronic arterial occlusive disease (p<0.0002). CONCLUSIONS: In diabetics occlusive disease in amputated legs is more severe in arteries above the ankle than in non-diabetics. However, no difference was demonstrated in this series in arteries of the ankle and foot. Diabetics are likely to have more medial calcification in the arteries than non-diabetics. Chronic inflammation in the arterial wall is associated with more severe stenosis.

[Possibilities of early functional diagnosis of arteriosclerosis obliterans of the main arteries of the leg].

The dynamics of blood flow volume was studied in the leg (by way of venous occlusive pletysmography), as well as the systolic pressure in the leg (by way of Winsor's volumetric determination), and the oscillometric index in the leg (by way of arterial oscillography with a sensitive optic recording system), these studies being conducted in 103 patients during reactive and work hyperenia corresponding in terms of the severity of the involvement of the major arteries to the initial, clinincally latent, stage of obliterative atherosclerosis. At the beginning of hyperemia diagnostically valuable and statistically significant shifts of the above parameters of blood supply to the leg were revealed in the patients, as compared to the normal individuals. Of diagnostic importance was not only the absolute degree of the changes in the beginning of hyperemia, but also the period of restoration of tthe initial level of the parameter in question. Some of the obtained quantitative criteria demonstrating the patency disorders in the major arteries of the extremities are recommended for early detection of persons with clinically latent obliterative atherosclerosis.

Haemodynamic effects of leg raising in patients undergoing coronary artery bypass grafting.

Twenty patients undergoing elective coronary artery bypass grafting were studied prospectively to evaluate the haemodynamic effects of passive leg raising. The patients were divided into two groups: those having good left ventricular function with ejection fraction of 0.50 or more (group I, n = 10) and those having poor left ventricular function with ejection fraction of upto 0.35 (group II, n = 10). Morphine-based anaesthetic technique was used and standard haemodynamic measurements were obtained at following stages: (1) control--20 to 30 min after induction of anaesthesia; (2) one minute, and (3) five min after raising both the legs; (4) one min, and (5) five min after the legs were repositioned. In group I, heart rate decreased from 71 +/- 9 to 66 +/- 8 beats/min (p < 0.001) at stage 1 and persisted throughout the study period. This was accompanied by a decrease in cardiac index, although, the statistical significance was achieved at stage 3 and 4 only. The haemodynamic changes observed in group II were of more severe magnitude. The heart rate decreased from 90 +/- 13 to 84 +/- 13 beats/min at stage 1 (p < 0.05) and persisted throughout the study with maximum decrease of 14 percent occurring at stage 3. The cardiac index decreased significantly from 2.4 +/- 0.3 to 2.0 +/- 0.5 L/min/m2 (p < 0.05) at stage 1. This persisted throughout the study except that it recovered at stage 4. The maximum decrease in cardiac index (20%) occurred at stage 2. In addition, systemic vascular resistance increased significantly from 1458 +/- 255 to 1830 +/- 420 dyne.sec.cm-5 (p < 0.05) at stage 1 and persisted throughout the study period. We conclude that passive leg raising should be undertaken with caution in patients with coronary artery disease especially in those who have poor left ventricular function.

[Leg ulcers and antiphospholipid antibodies. Prospective study of 48 cases].

BACKGROUND: Leg ulcres can be seen as manifestations of antiphospholipid syndromes but their pathogenic relationship with vascular thrombotic events secondary to antiphospholipid antibodies remains to be defined with precision. A significant association between anticardiolipin antibodies and venous leg ulcers has been described. We conducted this study to determine whether such an association is found in venous ulcers and if it could also be present in cases involving the arterial and/or arteriolar circulation. PATIENTS AND METHODS: From December 1995 to March 1997, 48 patients with leg ulcers involving venous (27 cases), arteriovenous (9 cases) or arteriolar (12 cases) circulations were admitted. The etiologic diagnosis was based on clinical presentation and duplex Doppler findings examining the superficial and deep venous and arterial circuits. Antiphospholipid antibodies were searched for in all cases: VDRL, ELISA for IgG and IgM antiphospholipid antibodies, antiprothrombinase circulating anticoagulant. RESULTS: Circulating anticoagulants were found in 22 of the 48 patients (46%): 12/27 (44%) involved venous leg ulcers (anticardiolipin antibodies, 5 cases; circulating anticoagulants, 4 cases; both, 2 cases); 1/9 involved arteriovenous ulcers (anticardiolipin antibodies, 5 cases); 9/12 involved arteriolar ulcers (anticardiolipin antibodies, 3 cases; circulating anticoagulants, 6 cases; both, 3 cases). Seven of the 9 patients also had severe arteritis. A past history of venous thrombosis was found in 3 cases with venous ulcers and antiphospholipid antibodies. One patient among the 5 with arteriolar ulcers had a past history of arterial thrombosis. DISCUSSION: Our cohort is too small for a formal conclusion but underlines two points: 1. antiphospholipid antibodies can be associated with venous ulcers independently of thrombosis history. The hypothesis that leukocyte stasis and endothelial cell activation causes an immune reaction implicating antiphospholipid antibodies has been put forward. The usefulness of an antiaggregate treatment or an anticoagulant treatment should be discussed, 2. The possible association between arteriolar ulcers and antiphospholipid antibodies requires further large scale studies.

[Peak oxygen uptake, ventilatory threshold and leg extension power in apparently healthy Japanese].

Peak oxygen uptake, ventilatory threshold (VT) and leg extension power were measured in 832 apparently healthy subjects (421 males, 411 females) aged 30-60 decades who performed medical examination at 4 health check up facilities. 1) Peak oxygen uptake was greater in male than female, and decreased with age in both sexes. Single regression formula on age were Y (ml/kg/min) = 46.6 - 0.36 x AGE, (r = 0.447, p < 0.001) in male and Y (ml/kg/min) = 35.3 - 0.23 x AGE, (r = 0.407, p < 0.001) in female. 2) VT was greater in male than female, and less decreased with age compared to maximal aerobic power. Single regression formula on age were Y (ml/kg/min) = 22.6 - 0.13 x AGE, (r = 0.371, p < 0.001) in male, Y (ml/kg/min) = 20.0 - 0.10 x AGE, (r = 0.301, p < 0.001) in female. 3) Leg extension power was greater in male than female, and decreased with age in both sexes. Single regression formula on age were Y (W/kg) = 31.9 - 0.27 x AGE, (r = 0.539, p < 0.001) in male and Y (W/kg) = 20.9 - 0.18 x AGE, (r = 0.510, p < 0.001) in female. Subjects in the present study showed height, weight and walk steps per day similar to those in National Nutrition Survey. Comparison of Peak oxygen uptake, ventilatory threshold and leg extensor power to previous studies revealed that these parameters were quite similar to the counterparts in the previous studies with less selection bias. It was suggested that subjects in this study were quite similar to normal Japanese population, and that Peak oxygen uptake, VT and leg extension power in the present study were of value for the evaluation of health related fitness in community and workplace.

Leg cramps in the elderly: prevalence, drug and disease associations.

To determine the prevalence of leg cramps in elderly outpatients and their association any underlying diseases and concomitant drug intake, we conducted a cross-sectional study using an in-depth questionnaire. A total of 365 patients aged 65 years and over (mean 78.5 years) attending our outpatient clinic participated in the study. The prevalence of leg cramps was 50%. Cramps were commoner in females (56%) than in males (40%). Although reported to occur anytime throughout the 24 hours, cramps were most prevalent at night (62%). In many patients, leg cramps were a long-standing complaint: 20% had been suffering with them for more than 10 years, whereas only 9% of patients reported them first starting within the last six months. Only 73 (40%) sufferers had informed their practitioner; of these, 39 (53%) received treatment, of whom 26 gained benefit. Leg cramps were strongly associated with peripheral vascular disease (odds ratio 2.9, 95% CI 1.89-4.55, p < 0.00001), arthritis (odds ratio 2.26, 95% CI 1.48-3.45, p = 0.0001) and female gender (odds ratio 1.96, 95% CI 1.28-3.03, p = 0.002). Heart failure, hypertension, diabetes mellitus and stroke were not significantly associated. Except for a causal association with analgesic use, no positive association could be shown with any other class of drugs, including diuretics.

In-patient management of leg ulcers.

OBJECTIVE: To review in-patient management of leg ulcers and to compare our experiences with those from other similar centres. DESIGN: A retrospective study. SETTING: University of Benin Teaching Hospital, Nigeria. PATIENTS: Forty five patients hospitalised with leg ulcers. RESULTS: There were 27 males and 18 females (MF 3:2). The age range was 8-90 years (mean 32.5 years). The commonest sites were around the ankle(55.6%) and the distal third of the leg (40%). Trauma, diabetes mellitus and sickle-cell disease accounted for the commonest aetiological factors(35.6%, 22.2% and 17.8% respectively). Coliforms and Staphylococcus aureus were the commonest organisms isolated on culture. All the patients had routine wound dressing and antibiotics but only 25 patients (56%) responded fully to this line of preliminary management. The other 20 patients had wound debridement in addition. Nineteen patients(42%) needed skin grafting while four patients (9%) had below-knee amputation. CONCLUSION: Our experience shows that leg ulcers whose nature portend an increase in morbidity and mortality are best managed as in-patients. The underlying causes should be addressed while local wound care is administered. Skin grafting and amputation should be employed when necessary.

[A case of infected renal cyst extending to leg abscess].

A 45-year-old woman was referred to our hospital with the chief complaint of left flank pain, left leg pain and loss of appetite. Computed tomography scan and magnetic resonance imaging demonstrated a large cystic mass in the left kidney, which we diagnosed as an infected renal cyst. Under ultrasonic guidance, percutaneous puncture and drainage of the renal cyst were performed. After her leg pain worsened, computed tomography revealed abscesses in the left leg, suggesting an infected renal cyst extending to the leg through the obturator foramen. Under general anesthesia, incision and drainage were performed. Cultures from the cyst and abscess fluid showed Klebsiella pneumoniae. Our case is the 82nd case of an infected renal cyst in the Japanese literature.

Fat transplantation to the buttocks and legs for aesthetic enhancement or correction of deformities: long-term results of large volumes of fat transplant.

BACKGROUND: A comprehensive review of the history of free fat transplantation reveals that since 1893 when Neuber used small pearls of fat taken from the arm to fill out depressed facial scars after trauma and underlying bone loss, free fat graft has been used with success in facial surgery, brain and nervous system surgery, various orthopedic uses, general surgery, craniofacial surgery, and cosmetic surgery. OBJECTIVE: To present the author's hypothesis that a fat graft in cosmetic surgery responds like other kinds of tissue grafts. This article was written as a result of the author's search for a way to avoid the most common complications of doing a buttock or leg augmentation with silicone prostheses and to find a better surgical procedure that is simpler, complementary with liposuction, and better able to deal with subtle body irregularities that do not justify a large and complicated procedure. METHODS: Over a period of 6.5 years, a total of 1350 liposculptures were performed. Eight hundred and seventy-nine patients had buttock augmentation. One patient had facial hemiatrophy and her face was treated twice with fat grafts. Four hundred and seventy patients had fat grafted onto their ankles and their legs for cosmetic reasons. One patient with polio sequelae and one male patient with agenesia of the gemellus muscles over his left leg were treated. The patients selected were not obese, but had moderate to severe lipodystrophy. The patients ranged in age from 18 to 65 years. RESULTS: The results of the buttock augmentations showed that there was a 0.5-1.0 cm reduction at 2 months. This persisted until the sixth month and until years later. These findings were seen in patients that had 3-5 kg less body weight after surgery than before or had 3-5 L of fat removed from their bodies. Patients who underwent ankle or leg augmentation experienced a 0.5 cm loss in diameter over the treated areas after the 1.5-month postoperative period. No more volume was lost after that. The areas kept the same parameters until the sixth month and also into later follow-ups. The few complications that our patients experienced appeared between days 2 and 15. The complications of 6.5 years occurred in 14 patients (1.037%). One case of erysipelas appeared on the 10th postoperative day. This patient reported that she was riding a bicycle and had a scratch over the left ankle, producing an infection with edema, erythema, and pain. Twelve patients got skin vesicles because of contact with micropore over the skin of the ankles. We treated those patients with local antibiotics, obtaining healing of the skin in about 5 days, with dryness and absence of the vesicles. No damage to the graft was observed. CONCLUSION: The hypothesis that applied fat grafts are real grafts was demonstrated. Not only are the grafts real, they are able to live and persist with the patients, growing if the patient gained weight over the gluteus area, and not losing circumference when reducing weight.

[Acute thrombosis of pelvic and leg veins in agenesis of the renal segment of the inferior vena cava].

A 19-year-old, otherwise asymptomatic man presented to the hospital of orthopaedic surgery with acute severe pain like lumbago. Symptomatic treatment was performed after extensive orthopaedic diagnostic procedures. On the third day after admission he showed clinical signs of deep vein thrombosis with painful swelling and livid discoloration of both legs. Colour duplex ultrasound revealed complete thrombosis of the leg and pelvic veins bilaterally, but the cranial extent was not clear. Contrast-enhanced helical computer tomography of the abdomen and the pelvis confirmed deep pelvic vein thrombosis and showed extension into the inferior vena cava. Moreover, the study revealed the agenesis of the renal segment of the inferior vena cava with collateral flow through dilated lumbar veins to enlarged azygous and hemiazygous, through vertebral and paravertebral venous plexus. The renals were drained via dilated capsular veins. The agenesis of renal vena cava is a very rare anomaly causing acute thrombosis of the deep leg and pelvic veins. Other risk factors of thromboembolic disease were not found. The patient was treated successfully with systemic thrombolysis. Therefore we used ultra-high streptokinase infusion (9 million units over 6 hours). Colour duplex ultrasound revealed good flow into deep leg and pelvic veins after three cycle of lysis. Magnetic resonance angiography of the abdomen and pelvis was performed to evaluate the successful fibrinolysis with complete recanalisation of the pelvic veins and to demonstrate the venous anatomy. Permanent oral anticoagulation with phenprocoumon is indicated to decrease the high rate of recurrent thrombosis. Compression stockings were prescribed. To prevent thrombosis, additional risk factors like smoking, immobilization and unusual physical activity should be strictly avoided.

[Pleomorphic carcinoma of the lung heralded as bilateral leg pain].

This is a case of a 70 year old male patient suffering from bilateral leg pain for 2 months. Physical examination disclosed clubbing. X-rays of the legs showed bilateral periosteal elevation with subperiosteal bone formation. 99TM-diphosphonate bone scan was negative. A search for malignancy revealed pleomorphic carcinoma of the right lung. Pain symptom disappeared 2 days after resection of the tumor. Repeated X-rays of the legs, three and a half months later showed no change and the clubbing persisted. Hence, unexplained bilateral leg pain should raise suspicion of hypertrophic osteoarthropathy, and elicit a search for secondary disease especially lung tumor. It is interesting to point out the negative bone scan and the rapid resolution of patient symptoms after resection of the tumor.

[Restless leg syndrome. Diagnosis and treatment].

INTRODUCTION: The restless legs syndrome is characterized by an unpleasant sensation in the legs which causes an imperative need to move the legs and is therefore considered to be a disorder of movement. When it appears before going to sleep, it may interfere with falling asleep and lead to a sleep-deficit. DEVELOPMENT AND CONCLUSIONS: It is a clinical condition with a satisfactory treatment, and improvement of the associated sleep disorder. The etiology is unknown, sometimes it is familial. The syndrome is increasingly often diagnosed, particularly in association with iron deficiency, during pregnancy, in chronic renal failure and in patients with peripheral neuropathy. Polysomnography is not necessary, unless one suspects an associated disorder of periodic leg movements. Treatment is by dopaminergic, opiate, benzodiazepine, anticonvulsant drugs or clonidine.

[Bone reconstruction, leg length discrepancy, and dislocation rate in 52 Wagner revision total hip arthroplasties at 44-month follow-up].

PURPOSE OF THE STUDY: The primary and secondary stability of a revision implant is highly compromised in cases with important loss of bone stock from the proximal femoral after severe femoral loosening. Several methods using implants with or without cement have been proposed for reconstruction after femoral bone loss. The purpose of this study was to analyze mid-term clinical and radiological outcome with the Wagner prosthesis for revision surgery. MATERIAL AND METHODS: Fifty-two cases of aseptic femoral loosening were treated with this method in 36 women and 14 men, mean age 70 years (range 32-92 years). None of the patients was lost to follow-up; five who died after 18 months were retained for analysis. Mean follow-up was 44 months (range 18-88 months). The mean preoperative Postel Merle d'Aubigné (PMA) score was 10.5 +/- 0.4. These patients had major bone loss (5 grade II, 24 grade III, 23 grade IV in the SOFCOT classification). The transfemoral access was used in 17 cases and bone grafts in 32. Clinical outcome was assessed with the PMA score and leg length discrepancy was measured. Radiographically, stability was assessed by measuring stem impaction and progression of radiolucent lines. RESULTS: The overall functional score was significantly improved from 10.5 +/- 0.4 preoperatively to 14.6 +/- 0.5 (p<0.001). All items on the score improved but pain relief was the most notable. Improvement in the gait score was limited due to persistent limping in 39 patients. Leg length discrepancies were found in 8 patients with 6 shortenings and 2 lengthenings. The clinical situation remained stable after one year. The implant remained stable in 48 patients (92 p. 100) and stem impaction was observed in 4 before 12 months. Two of these cases required a second revision. Metaphyseal reconstruction was observed in 42 patients (81 p. 100), including 24 (46 p. 100) who exhibited homogeneous reconstruction with trabeculation. The reconstruction did not progress further after 18 months postoperatively. Complications included four dislocations and five revision procedures (three for cup loosening, two for femoral pivot instability). DISCUSSION: The functional outcome was similar to results reported in the literature, including the high frequency of limping that was caused by various factors (valgus prosthesis neck, leg length discrepancy, muscle deficits). Leg length discrepancies resulted from defective positioning or impaction at loading. Standard radiographic series allowed an assessment of stem impaction. Our low rate could be due to delayed weight bearing. La reconstruction of bone loss did not progress after 18 months and was independent of bone grafting, route of access, and the initial degree of loosening. The high frequency of dislocations with this type of implant can be prevented by horizontalization of the acetabulum and use of anti-dislocation inserts at the first intention revision. CONCLUSION: Our results with the Wagner prosthesis are satisfactory both clinically and radiographically. The two drawbacks of this implant (limping and dislocation), partly due to the design of the femoral stem, have led us to study a new implant that preserves good distal anchoring and optimizes the proximal biomechanics of the hip joint.

Effect of sequential intermittent pneumatic compression on both leg lymphedema volume and on lymph transport as semi-quantitatively evaluated by lymphoscintigraphy.

Sequential Intermittent Pneumatic Compression (SIPC) is an accepted method for treatment of peripheral lymphedema. This prospective study evaluated the effect in 11 patients of a single session of SIPC on both lymphedema volume of the leg and isotope lymphography (99Tc dextran) before SIPC (control) and 48 hours later after a 3 hour session of SIPC. Qualitative analysis of the 2 lymphoscintigrams (LS) was done by image interpretation by 3 physicians on a blind study protocol. The LS protocol attributed an index score based on the following variables: appearance, density and number of lymphatics, dermal backflow and collateral lymphatics in leg and thigh, visualization and intensity of popliteal and inguinal lymph nodes. Volume of the leg edema was evaluated by measuring limb circumference before and after SIPC at 6 designated sites. Whereas there was a significant reduction of circumference in the leg after SIPC (p<0.05), there was no significant difference in the index scores of the LS before and after treatment. This acute or single session SIPC suggests that compression increased transport of lymph fluid (i.e., water) without comparable transport of macromolecules (i.e., protein). Alternatively, SIPC reduced lymphedema by decreasing blood capillary filtration (lymph formation) rather than by accelerating lymph return thereby restoring the balance in lymph kinetics responsible for edema in the first place.

[Hydroxyurea-induced leg ulcers in patients with chronic myeloproliferative disorders].

INTRODUCTION: Hydroxyurea (HU) is usually a well-tolerated antineoplastic agent, which is commonly used in the treatment of myeloproliferative disorders. Dermatological abnormalities are often seen in patients receiving long-term HU therapy. Leg ulcers have been reported occasionally. MATERIAL AND METHODS: We carried out a prospective and descriptive study of patients who developed leg ulcers while receiving HU therapy. RESULTS: Between 1.1.1997 and 1.2.1998, chronic cutaneous leg ulcers were found in five out of a total of 28 patients treated with HU. The average age was 76 years (64-87 years). Two patients had chronic myelogenous leukaemia in a non-accelerated phase, two polycytaemia vera, and one essential thrombocytosis. The average duration of HU therapy was 30 months (10-55 months) before ulcerations appeared. These were typically located on the malleolar and/or perimalleolar area, and were very painful. HU therapy was discontinued and replaced by busulphan or anagrelide. Within 1.5-11 months of discontinuation of the treatment, the wounds had healed or improved. DISCUSSION: We found a surprisingly high number of cutaneous leg ulcers in patients on HU therapy for chronic myeloproliferative disorders. We believe this disabling complication should be given greater attention and recommend that it is included in the description of the side effects of the drug.

[Nutritional status assessment of patients with leg ulcers].

INTRODUCTION: Nutritional deficiencies may delay the wound healing process. The aim of this study was to evaluate the prevalence of protein malnutrition in patients presenting with a leg ulcers and to determine which clinical data can predict malnutrition on population. PATIENTS AND METHODS: This prospective survey included community patients, hospitalized in rehabilitation care unit for treatment of a leg ulcer unhealed for at least 3 months. Clinical, anthropometric and biological data were collected on admission. RESULTS: Sixty-six patients, mean age 72.9 +/- 16.3 years, were included. Fifty-three p. 100 presented wound surfaces over 30 cm(2); 59 p. 100 of the ulcers had lasted for more than one year; 62 p. 100 of the ulcers were venous. 48.5 p. 100 of the patients exhibited protein malnutrition defined by biological criteria, associated with an inflammatory syndrome in 66 p. 100. Anemia and an inflammatory syndrome were present in respectively 59 and 58 p. 100 of the patients. Neither anthropometric measurements nor nutritional intake or wound characteristics significantly differenced between patients with malnutrition or not. Hypoalbuminemia was significantly more frequent and severe in patients aged over 70. DISCUSSION: Protein malnutrition prevalence is very high in patients with leg ulcers, particularly in the elderly. Since nutritional interview or clinical data failed to predict protein malnutrition, systematic biological assessment is justified in all patients with leg ulcers.
