In elderly patients, even those with a typical venous (stasis) ulcer, coexisting conditions like peripheral arterial insufficiency and diabetes are very common. Therefore, all elderly patients with leg ulcers should have a complete medical assessment. The mainstay of treatment for venous ulcers is compression therapy, exercise and leg elevation at rest. Long term treatment with double bandages (zinc paste bandages and elastic compression), changed once weekly, is the recommended standard treatment in the elderly. Hydrocolloid dressings are also suitable for long term treatment in clean ulcers, and should be changed once or twice weekly and combined with compression. Sloughy, exudating ulcers might need redressing daily with a desloughing agent for a short period of time. The risk of sensitising patients with chronic leg ulcers is high and few topical preparations, with low antigenicity, should be used. Infection and ulcerated skin cancers should be ruled out in nonhealing ulcers if the patient complies with compression therapy. After healing, the patient should be advised to continue compression therapy with stockings to prevent recurrences. New noninvasive techniques for investigation of venous insufficiency can select patients suitable for venous surgery, but many elderly patients are not interested in surgery or have other ailments that prevent surgery.

Treatment of leg ulcers should consider two aspects, i.e. the exact underlying condition (main cause and contributing factors) and local conditions. Compression therapy remains the corner-stone of the therapeutic concept. A compression of 35 mmHg at the distal calf improves insufficient venous function. A systolic ankle pressure of < or = 80% of blood pressure (ankle-arm-index < or = 0.8) requires reduction of compression therapy. At an ankle pressure below 80 mmHg compression should not be used. If superficial reflux is the major cause of chronic venous insufficiency, vein stripping should be considered. Contributing diseases like heart insufficiency, anemia or diabetes may require general medical care. Local contributing factors like reduced mobility of the ankle joint and lymphostasis may require physical therapy, and calcification of the wound bed should be excised. Local treatment considers ulcer bed and border. The ulcer bed needs debridement and moist wound care. Infection is treated with systemic antibiotics, according to the antibiogram. Tetanus immunization is required for all leg ulcer patients. Some centers report good results with endoscopic subfascial decision of perforator veins, paratibial fasciotomy and excision of fibrous tissue. Local application of recombined growth factors is currently under clinical evaluation. Adjuvant pharmacotherapy plays a minor role in the treatment of venous leg ulcers. An efficient treatment of the underlying cause combined with optimal wound care are the key to therapeutic success.

An abnormality in platelet aggregability or fibrinolysis, namely elevated activity of plasminogen activator inhibitor-1 (PAI-1), has been recently documented in patients suffering from Klinefelter's syndrome associated with leg ulceration without underlying venous insufficiency. To determine whether increased PAI-1 activity is a general feature of Klinefelter's syndrome, or more specifically associated with leg ulceration, we investigated PAI-1 influencing parameters and PAI-1 activity in two groups of patients: (i) Klinefelter patients suffering from leg ulceration (n = 7); and (ii) Klinefelter patients without leg ulceration (n = 6). On analysing PAI-1 influencing parameters such as age, body mass index, triglycerides, C-reactive protein, testosterone, smoking behaviour, the presence of diabetes mellitus, and arterial hypertension, respectively, we found no statistically significant differences between the two groups. However, PAI-1 activity in group 1 was highly significantly elevated compared with that in group two patients (P < 0.005). We conclude that (i) PAI-1 activity is not elevated in Klinefelter's syndrome in general; (ii) elevation of PAI-1 activity in patients suffering from Klinefelter's syndrome does not appear to be secondary to PAI-1 influencing parameters; and (iii) elevation of PAI-1 activity may play a crucial role in the pathogenesis of leg ulceration in Klinefelter's syndrome. Therefore, a therapy for leg ulceration in Klinefelter's syndrome that aims to return the elevated PAI-1 activity to normal should be explored.

The non-healing leg ulcer is examined by discussing three disease processes: peripheral vascular occlusive disease (PVOD), chronic venous insufficiency (CVI), and vasculitis. For PVOD, management decisions are based on risk factors and disease history. Comprehensive management includes the discontinuation of smoking, exercise conditioning and regulation of diabetes, hyperlipidemia, hypertension, and the appropriate application of anticoagulant/antiplatelet drugs. Methods of surgical management include bypass with autogenous or synthetic material in addition to reconstructive surgery with patch angioplasty or extra-anatomic bypass, amputation, percutaneous transluminal angioplasty/stents, thrombolytic infusion, atherectomy, intraluminal ultrasound, and angioscopy. The optimal healing environment for all ulcers prevents contamination, pain, and fluid loss. In CVI, higher venous pressure in the veins of the lower limb during exercise results in ambulatory venous hypertension and ulceration. Various theories are associated with the disease and ulceration process; the classic treatment of elevation, ambulation, and compression for venous disease remains unchallenged. Diagnosis is based on history, physical examination, invasive venography, and/or non-invasive studies. Two groups of vasculitic disorders that share varying degrees of vascular inflammation and necrosis are arteritis (lupus, erythematosus, periarteritis nodosa, dermatomyositis) and blood dyscrasias (sickle cell disease, thalassemia). Leg ulcers associated with vasculitis are due to inadequate tissue oxygenation at the local level, are typically chronic, slow to heal, and commonly recur.

A 44-year-old woman who weighed 130 kg (height 158 cm, BMI 52) with a complicated psychiatric history was referred for obesity surgery because of severe sleep apnea, obesity hypoventilation syndrome with frequent pneumonias, arterial hypertension, diabetes mellitus, polyarthralgia and back pain, venous insufficiency, dysmenorrhea, severe heartburn, and incisional hernia. From childhood until 1983, she had undergone 106 operations, mainly for septic/pyemic and intra-abdominal abscesses, 86 of them under general anesthesia. In the 4 years before undergoing bariatric surgery, she had gained 40 kg, nonoperative attempts at weight reduction had failed. Some months before obesity surgery she could fall asleep while standing, and she noticed an entire loss of capacity for work. Respiratory disturbance index measured during sleep by Mesam-4 device was 68 events per hour. Preoperative controlled positive airway pressure (C-PAP) therapy was used. Vital indications for weight reduction were established. Bariatric surgical steps included six operations: (1) vertical banded gastroplasty (VBG); (2) relaparotomy with suspicion of peritonitis, no complications found; (3) hernioplasty simultaneously with panniculectomy; (4) revision and removal of additional flap because of marginal skin necrosis; (5) bilateral thigh dermatolipectomy simultaneously with right-side saphenectomy; and (6) removal of intramammary abscess. Twenty-four months after VBG, she had lost 39 kg (56.5 % EWL) and was doing rather well. Obesity-related diseases except back pain were relieved.

Impaired cutaneous wound healing is a common complication in diabetes, ischemia and venous insufficiency of lower extremities, and in long-term treatment with corticosteroids or other immunosuppressive agents. In development of gene therapy for wound repair, expression of therapeutic transgenes should be precisely targeted and controlled. Here, we describe a recombinant adenovirus RAdFiRE-EGFP, in which a growth factor inducible element (FiRE) of the murine syndecan-1 gene controls the expression of enhanced green fluorescent protein (EGFP) reporter gene. Treatment of RAdFiRE-EGFP-transduced murine epidermal keratinocytes in culture with FiRE-activating growth factor markedly enhanced the expression of EGFP. In ex vivo organ culture of wounded murine skin transduced with RAdFiRE-EGFP, the EGFP expression was specifically detected in wound margin keratinocytes, but not in intact skin. Activity of EGFP was first detected 2 days after a single application of RAdFiRE-EGFP and persisted up to 10 days. Similarly, FiRE-driven EGFP expression was detected specifically in epidermal keratinocytes in the edge of incisional wounds in murine skin transduced with RAdFiRE-EGFP. In contrast, adenovirus-mediated lacZ expression driven by CMV promoter was detected scattered in epidermal, dermal and subcutaneous layers in ex vivo and in vivo wounds, as well as in intact skin. These data demonstrate the feasibility of FiRE as a tool for transcriptional targeting of adenovirus-mediated transgene expression to cutaneous wound edge keratinocytes.

Evaluating tetanus immune status is not yet the usual clinical practice regarding patients with chronic ulcers or myasis. However, of 858 tetanus patients at Hospital Couto Maia (Salvador, Bahia, Brazil) aged 1 year or above, 2 had pressure ulcers and 17 had chronic ulceration of the lower limbs where these skin lesions were the ports of entry for Clostridium tetani. In these 19 cases, the following predisposing factors were described: venous insufficiency (n=6), sickle cell anemia (n=2), Hansen s disease (n=1), malnutrition (n=1), diabetes mellitus (n=1), trauma (n=1) and unknown factors (n=7). In 6 other cases, in addition to the Hansen s disease patient, the port of entry for tetanus was the site of extraction of Tunga penetrans larvae. In these 25 cases, the majority of patients (68%) were over 40 years old (17/25) and all of these patients stated that they had either not followed a tetanus toxoid vaccination regimen (19/25), or had partially completed such a regimen, or did not give precise information (6/25). Among the same series studied, over half (52%) of the patients died (13/25). We conclude that tetanus prevention must be included in the treatment of chronic skin ulcer patients, vaccination coverage should be increased among older people, and strategies aimed at improving coverage for all age groups must be reviewed.

The popularity of the sural artery flap has increased markedly throughout the years, and favorable results are reported almost uniformly. Previous publications have mainly presented results of small groups and of predominantly younger patients with posttraumatic defects, or they have reported technical modifications of the sural artery flap. The authors have increasingly used the reversed sural artery flap in a high-risk, critically multimorbid, and older patient population, and in contrast to the results of other authors, a considerable necrosis rate of 36 percent was seen. For the first time, a detailed, critical, retrospective complication analysis of 70 sural artery flaps is presented. The results reveal the following risk factors, which can potentially impair successful defect coverage and thus contribute to flap complications: concomitant diseases, particularly diabetes mellitus; peripheral arterial disease or venous insufficiency, which increase the risk of flap necrosis five-fold to six-fold; and patient age of over 40 years, because of an increased rate of comorbidity, underlying osteomyelitis, and the use of a tight subcutaneous tunnel. However, age alone did not seem to represent a risk factor by itself. Given the results of the analysis, the operative procedure was altered, as follows. In cases in which a lesser saphenous vein cannot be found, a delay procedure is recommended, or the flap is not utilized. In addition, an external fixation device seems to facilitate postoperative care markedly without adding specific complications; it is recommended in most patients. This analysis emphasizes specific risk factors that result in higher complication rates of the sural artery flap, and it leads to more realistic and appropriate expectations for this flap.

This article reviews several aspects of the association between obesity and cancer. Current perspectives of cancers of the breast, endometrium, colon and prostate are described. Obesity is a growing problem in contemporary societies, due to the rapid adoption of a modernized lifestyle that results in increased carbohydrate and fat-rich dietary intake, reduced physical activity and extended life expectancy. More than half of adult Americans are overweight or obese, and so is the population of many other countries. There are several definitions for the state of obesity. The body mass index (BMI), which measures overall adiposity, is universally available, the easiest to determine, and therefore the most commonly studied. Anthropometric measurements of subcutaneous fat distribution, such as measurement of girth, circumference of the arms, hips and thighs, or of skinfolds in various body regions are also often used. They allow to categorize the distribution of subcutaneous fat into android and gynoid types (den Tonkelaar, Seidell et al., 1994; Huang, Willett et al., 1999). The android, or abdominal, fat is determined from the waist to hip ratio, and is of particular relevance to cancer. Increased body weight and fat are associated with high health risks, and therefore body fat distribution and BMI are major predictors of obesity associated risks (Calle, Thun et al., 1999; "Overweight, obesity, and health risk," Yanovski, 2000). These include diabetes mellitus type 2, coronary heart disease, sleep apnea and pulmonary dysfunction, stroke, diseases of the gallbladder, liver and the musculoskeleton, reproductive dysfunction, venous insufficiency, deep vein thrombosis, poor wound healing, and more (Pi Sunyer, 1993; "Overweight, obesity, and health risk", Yanovski, 2000). All these are associated with increased mortality, especially in individuals with other risk factors (Calle, Thun et al., 1999). Cancer is also associated with obesity (Garfinkel, 1985), and the present paper attempts to summarize current perspectives of this association, especially in cancers of the breast, endometrium, colon and prostate.
