Clinician awareness of the importance of recognizing, assessing, and ultimately addressing the negative impact of chronic wounds on patient quality of life is increasing. One hundred, eighteen (118) patients (average age 78 years) participated in a study to evaluate the use of the Medical Outcomes Short Form-36 for assessing the health-related quality of life of patients with chronic leg ulceration. Most patients (104, 88%) were treated at home by community nurses. A medical history was obtained and patients completed the Short Form-36 questionnaire at baseline and after 12 weeks of receiving standard ulcer care. Published normative data were used to ascertain the effect of leg ulcers on health-related quality of life. Short Form-36 responsiveness was determined by comparing baseline and 12-week scores. Results suggest that the questionnaire is reliable for five of eight Short Form-36 domains (alpha > 0.8), with the remainder alpha > 0.7. Compared to age-sex adjusted published normative scores, patients with leg ulcers had significantly lower mean scores in the following domains: role-emotional (d = 28.6, P <0.001), social functioning (d = 22.8, P <0.001), role-functioning (d = 20.8, P <0.001), role-physical (d = 20.7, P <0.001), and bodily pain (d = 12.3, P <0.001). Short Form-36 scores barely changed between baseline and the 12-week assessment, but bodily pain improved in the 31 patients whose ulcers healed during that time (d = 14.6, P = 0.006; SRM = 0.60). Pain did not improve in patients whose ulcers remained open (d = -2.1, P = 0.45). Compared to patients whose ulcers did not heal, patients with healed ulcers experienced greater improvements in the following domains: body pain (d = 16.8, P = 0.003), mental health (d = 9.4, P = 0.013), role-physical (d = 19.7, P = 0.06), role-emotional (d = 17.2, P = 0.12), and vitality (d = 9.0, P = 0.052). The results of this study suggest that leg ulcers reduce patient quality of life and that the Short Form-36 can be used to ascertain their impact

Compartment syndrome is a limb-threatening and occasionally life-threatening injury. It occurs whenever the tissue pressure (referred to as interstitial pressure) within a closed anatomic space is greater than the perfusion pressure. Untreated, compartment syndrome leads to tissue necrosis, permanent functional impairment and, if severe in large compartments, renal failure and death. Compartment syndrome can occur within any muscle group located in a compartment. It is most common following an event that severely damages a muscle, like a crushing or twisting injury. Mechanisms of injury that involve circumferential burns, ischemia and tourniquets can cause compartment syndrome. Motorcyclists who suffer lower-extermity injuries in accidents are a high-risk group. A tough membrane referred to as a fascia covers muscle groups, forming a compartment for the muscle. In normal circumstances, this arrangement allows the muscle to function more efficiently, but if the muscle is injured in any way, the fascia limits the amount of swelling that can occur. This in turn restricts the flow of blood through the affected region. The first compromised function within the compartment is the flow of lymph and venous blood. If there are sensory nerves running through the compartment, they will not function correctly, causing the numbness, tingling and, later, the pain associated with compartment syndrome. With more swelling, arterial flow is compromised, pain worsens and motor function is impaired. An artificial way of producing a compartment syndrome is to place a cast or splint around a damaged extermity, compressing it. This is a way emergency personnel can compromise an injury and cause long-term consequences for the patient. Recovery is achieved by surgically opening the compartment involved (a fasciotomy) and releasing the pressure. The muscle at first will swell outside the compartment, but then it recovers, swelling is reduced and normal function can be recovered. Prehospital treatment of extremity injuries that will prevent or limit compartment syndrome is immobilization, elevation and cooling. Recognition of the syndrome later in its course, as in this case, requires the EMT to remove the patient to an appropriate emergency department. Prehospital providers need to recognize that many mechanisms of injury can produce this syndrome, even those that seem relatively minor. All injured patients should be educated to seek care should the symptoms of numbness, deep pain and coolness to the distal extremity occur. This case involved a patient who, from a relatively minor mechanism of trauma, experienced an internal disruption of the muscle group controlling the thumb (thenar mass). The early swelling in the thenar compartment resulted in the patient experiencing a tingling sensation in his left thumb. In many cases, such an injury would be referred to as a "stinger" (a temporary neurological deficit due to a sudden and excessive stimulation of a neurologic plexus or junction). But this patient had more swelling in the compartment, resulting in a lack of circulation manifested by a cool extremity, poor capillary refill and decreased pulse oximetry. Luckily, this officer recognized the need for medical evaluation of what appeared to be a minor injury and was returned to duty with no permanent impairment.

Erythropoietin (Epo) has been shown to have potent anti-apoptotic activity in central nervous system neurons in animal models of ischaemic injury. Recently, Epo and its receptor (EpoR) have been identified in the peripheral nervous system [Campana & Myers (2001), FASEB J., 15, 1804-1806]. Herein, we demonstrate that in painful neuropathy caused by L5 spinal nerve crush (SNC), therapy with recombinant human Epo (rhEpo) reduced dorsal root ganglion (DRG) apoptosis and pain behaviours. Quantification of both DRG neurons and satellite cells revealed that vehicle-treated, crush-injured DRGs had 35.5 +/- 8.3% apoptotic neurons and 23.5 +/- 2.36% satellite cells compared with 7.5 +/- 6.3% apoptotic neurons and 6.4 +/- 3.94% satellite cells in rhEpo-treated, crush-injured DRGs (P < 0.05). While rhEpo-treated animals were not initially protected from mechanical allodynia associated with L5 SNC, rhEpo did significantly improve recovery rates compared to vehicle-treated animals (P < 0.01). Systemic rhEpo therapy increased JAK2 phosphorylation, a key anti-apoptotic signalling molecule for Epo-induced neuroprotection, in DRGs after crush. Dual immunofluorescence demonstrated Epo-induced JAK2-p was associated with both neuronal and glial cells. JAK2-p was associated with NF200-positive large neurons and with smaller neurons. This population of small neurons did not colocalize with IB4, a marker of nonpeptidergic, glial derived growth factor-responsive neurons. The findings link anti-apoptosis activities of Epo/EpoR/JAK2 in DRG neurons capable of inducing protracted pain states with reductions in pain behaviours, and therefore support a role for Epo therapy in the treatment of neuropathic pain.

An increasing number of women with vulval problems and pain attend Olafiaklinikken, the centre for sexually transmitted infection (STI) in Oslo. The aim of the study was to investigate the prevalence of long-standing vulval problems and entry dyspareunia in a consecutive sample of STI-clinic visitors in Oslo. A self-administered questionnaire was distributed before and independent of the consultation. Response rate was 89.6% (502/560). Mean and median age were 25.9 and 24.0 years respectively, range 16-65 years. Vulval soreness, burning, dryness and fissures present for at least three months were reported by 23.1% (116/502), entry dyspareunia by 6.9% (34/494). Independent risk factors for dyspareunia were a history of >/=4 treatments for vulvovaginal candidiasis during the last year, reported by 34.6%, odds ratio (OR) 4.45, 95% confidence interval (CI) 1.81-11.0, and a history of bacterial vaginosis, reported by 42.4%, OR 2.34, 95% CI 1.11-4.92. Contraceptive methods, hygienic habits, a history of STIs, depression or sexual abuse were factors unrelated to longstanding symptoms. Investigation with regard to longstanding vulval problems and entry dyspareunia is required for a certain group of sexually transmitted disease-clinic visitors in Oslo, and referral to a special service for vulva patients would be beneficial for selected patients.

Capsaicin (trans-8-methyl-N-vanillyl-6-nonenamide), a natural product of Capsicum species, is known to induce excitation of nociceptive terminals involved in pain perception. Recent studies have also shown that capsaicin not only has chemopreventive properties against certain carcinogens and mutagens but also exerts anticancer activity. Here, we demonstrated the antiangiogenic activity of capsaicin using in vitro and in vivo assay systems. In vitro, capsaicin inhibited vascular endothelial growth factor (VEGF) -induced proliferation, DNA synthesis, chemotactic motility, and capillary-like tube formation of primary cultured human endothelial cells. Capsaicin inhibited both VEGF-induced vessel sprouting in rat aortic ring assay and VEGF-induced vessel formation in the mouse Matrigel plug assay. Moreover, capsaicin was able to suppress tumor-induced angiogenesis in chick chorioallantoic membrane assay. Capsaicin caused G(1) arrest in endothelial cells. This effect correlated with the down-regulation of the expression of cyclin D1 that led to inhibition of cyclin-dependent kinase 4-mediated phosphorylation of retinoblastoma protein. Signaling experiments show that capsaicin inhibits VEGF-induced p38 mitogen-activated protein kinase, p125(FAK), and AKT activation, but its molecular target is distinct from the VEGF receptor KDR/Flk-1. Taken together, these results demonstrate that capsaicin is a novel inhibitor of angiogenesis and suggest that it may be valuable to develop pharmaceutical drugs for treatment of angiogenesis-dependent human diseases such as tumors.

Cannabinoids, the active components of marijuana and their endogenous counterparts were reported as useful analgetic agents to accompany primary cancer treatment by preventing nausea, vomiting, and pain and by stimulating appetite. Moreover, they have been shown to inhibit cell growth and to induce apoptosis in tumor cells. Here, we demonstrate that anandamide, Delta(9)-tetrahydrocannabinol (THC), HU-210, and Win55,212-2 promote mitogenic kinase signaling in cancer cells. Treatment of the glioblastoma cell line U373-MG and the lung carcinoma cell line NCI-H292 with nanomolar concentrations of THC led to accelerated cell proliferation that was completely dependent on metalloprotease and epidermal growth factor receptor (EGFR) activity. EGFR signal transactivation was identified as the mechanistic link between cannabinoid receptors and the activation of the mitogen-activated protein kinases extracellular signal-regulated kinase 1/2 as well as prosurvival protein kinase B (Akt/PKB) signaling. Depending on the cellular context, signal cross-communication was mediated by shedding of proAmphiregulin (proAR) and/or proHeparin-binding epidermal growth factor-like growth factor (proHB-EGF) by tumor necrosis factor alpha converting enzyme (TACE/ADAM17). Taken together, our data show that concentrations of THC comparable with those detected in the serum of patients after THC administration accelerate proliferation of cancer cells instead of apoptosis and thereby contribute to cancer progression in patients.

The objective of the study was to determine the association of neurocognitive impairment with health-related quality of life (HRQoL) in patients receiving highly active antiretroviral therapy (HAART). Seventy subjects were cross-sectionally analysed with a standardized neuropsychological test battery and a questionnaire including an Italian translation of the MOS-HIV Health Survey. The presence of neurocognitive impairment was significantly associated with lower HRQoL scores: pain (P = 0.03), physical functioning (P = 0.01), role functioning (P = 0.01), social functioning (P = 0.029), mental health (P = 0.001), energy (P = 0.036), health distress (P = 0.002), cognitive functioning (P = 0.05), current health perception (P <0.001), physical health summary score (PHS) (P = 0.005), mental health summary score (MHS) (P = 0.002). Years of education (odds ratio [OR] 0.79; 95% confidence interval [CI] 0.65-0.96), PHS (OR 0.71; 95% CI 0.54-0.95) and MHS (OR 0.67; 95% CI 0.51-0.88) were also associated with cognitive impairment. Neurocognitive impairment in patients receiving HAART was associated with reduced HRQoL. Identifying cognitive impairment may provide motivation for additional treatment to help patients to compensate for deficits in functioning.

The objective of the study was to review the indications for scrotal ultrasound scans and to assess the impact on patient management. We therefore performed a retrospective analysis. Case notes of all males referred for a scrotal ultrasound between April 1998 and March 2001 were studied. Data were extracted for the following: age, presenting complaints, physical findings on examination, results of a full sexual screen, treatment, ultrasound result and the designation of the person requesting the scan. All data were tabulated and summated using 'Windows Excel' software. One hundred and fifteen men were referred for an ultrasound in this period of time. None had an ultrasound more than once. Of these, 25 subjects could not be included as they either failed to attend for their scan (n=8) or their notes could not be traced (n=17). Twelve subjects were excluded as they did not fit the selection criteria (n=12). Median age was 30 years (Range 19-61 years). The commonest reason for referral was testicular pain (n=43) followed by testicular lump (n=19). The commonest abnormality on examination was an inflamed epididymis (n=18). Forty-two of the ultrasound scans were normal. A testicular mass was detected in only five of the 78 patients (6.4%), of which one was a malignancy (1.2%). A direct referral to a urologist for further management was made in only nine patients. Scrotal ultrasound for pain has limited impact on patient management apart from reassuring a worried patient. However, it remains an important investigation in the management of a suspected testicular lump.

The main objective of this research was to determine the initial psychometric properties of the Faces Pain Scale - Revised (FPS-R) as a measure of pain intensity for use with Catalan children and adolescents. Results of the Catalan version of this scale (FPS-R-C) are similar to those obtained with the original instrument. In order to assess the validity and reliability of the FPS-R-C, two different samples were studied. The first sample contained 124 hospitalized children and adolescents (mean age 10.86; SD 2.5). They were asked to rate their affective state on the Faces Affective Scale (FAS) and the intensity of their pain on the FPS-R-C and the Coloured Analogue Scale (CAS). The pain intensity ratings reported with FPS-R-C and CAS were very similar, correlations ranging from 0.83 to 0.9. The relationship between the intensity of pain experienced and children's affective state was also statistically significant (R = 32, P < 0.01). The second sample contained 247 schoolchildren (mean age 9.43; SD 1.55), who were asked to imagine themselves in eight hypothetical painful situations and rate the degree of pain using the FPS-R-C and the CAS (correlations ranging from 0.83 to 0.96). Test-retest correlations on this questionnaire (Painful Events Inventory) ranged from 0.26 to 0.70. Overall, these results provide preliminary evidence of the reliability, and convergent and criterion-related validity of the FPS-R-C. Moreover, all participating subjects were asked to choose the pain scale they preferred the most. Our data suggest that, regardless of their age and/or gender, the subjects prefer the FPS-R-C to the CAS.

The cause of category III A prostatitis, chronic prostatitis/chronic male pelvic pain syndrome category A (CP/CPPS A), is uncertain. Treatments for it are based on consensus opinion rather than on scientific data. Our aim was to examine the effect of zafirlukast, a leucotriene antagonist, on the symptoms of CP/CPPS A in our genitourinary (GU) medicine unit. CP/CPPS A was diagnosed by comparative white cell counts of split urine (Stamey) analysis or by finding an excess of polymorphs in expressed prostatic fluid. Symptom change was assessed by the National Institutes of Health Chronic Prostatitis Symptom Index (CPSI). Patients were given zafirlukast or placebo for four weeks in a random double-blind fashion. All patients also received doxycycline. In all, 31 patients were asked to participate and 17 entered the study. No difference in outcome could be shown between the active (10) and placebo (seven) patients. Zafirlukast cannot be demonstrated to be useful in the symptomatic treatment of CP/CPPS A. The problems of recruitment into this study (in spite of a large number of patients with prostatic type pain being seen in our unit) suggest that multicentre treatment trials using non-invasive diagnostic techniques such as the CPSI (rather than single GU medicine units diagnosing CP/CPPS A by uncomfortable direct prostatic testing) are likely to be the most effective and objective methods of undertaking treatment trials in the CP/ CPPS A field in the future.
