Abstract
BACKGROUND Patients with allergic rhinitis (AR) increasingly use complementary medicine. The aim of this study was to determine whether traditional Chinese therapy is efficacious in patients suffering from seasonal AR. METHODS Fifty-two patients between the ages of 20 and 58 who had typical symptoms of seasonal AR were assigned randomly and in a blinded fashion to (i) an active treatment group which received a semi-standardized treatment of acupuncture and Chinese herbal medicine, and (ii) a control group which received acupuncture applied to non-acupuncture points in addition to a non-specific Chinese herbal formula. All patients received acupuncture treatment once per week and the respective Chinese herbal formula as a decoction three times daily for a total of 6 weeks. Assessments were performed before, during, and 1 week after treatment. The change in severity of hay fever symptoms was the primary outcome measured on a visual analogue scale (VAS). RESULTS Compared with patients in the control group, patients in the active treatment group showed a significant after-treatment improvement on the VAS (P = 0.006) and Rhinitis Quality of Life Questionnaire (P = 0.015). Improvement on the Global Assessment of Change Scale was noted in 85% of active treatment group participants vs 40% in the control group (P = 0.048). No differences between the two groups could be detected with the Allergic Rhinitis Symptom Questionnaire. Both treatments were well-tolerated. CONCLUSIONS The results of this study suggest that traditional Chinese therapy may be an efficacious and safe treatment option for patients with seasonal AR.

Abstract
BACKGROUND AND AIMS Coeliac disease (CD) is characterised by the presence of autoantibodies against tissue transglutaminase (tTG), the endomysial autoantigen. This study was performed to determine the effect of purified autoantibodies on the enzymatic activity of tTG. METHODS Total IgA and IgG class antibodies and purified anti-tTG autoantibodies were isolated from sera of untreated patients with CD and controls. The inhibitory capacity of the antibodies on tTG activity was checked by a fluorometric assay based on the incorporation of monodansyl cadaverine into casein and by tTG-catalysed cross linking of biotinylated cadaverine to gliadin. RESULTS The enriched IgA and IgG fractions of five patients with CD and three controls resulted in no significantly different inhibition of enzymatic activity. In contrast, the use of affinity purified anti-tTG autoantibodies of 12 patients with CD led to a dose dependent reduction of tTG activity, compared to control immunoglobulins (n=6). However, the remaining activity was sufficient for cross linking of cadaverine into gliadin, and enzymatic tTG activity was only blocked completely by high concentrations of a monoclonal antibody, which is directed to the active centre of tTG. CONCLUSIONS Despite a partial inhibitory effect of isolated anti-tTG autoantibodies from patients with CD, residual enzymatic activity remains sufficiently high to cast doubt on their in vivo relevance.

Abstract
BACKGROUND/AIMS Ulcer healing involves expression of various growth factors such as epidermal growth factor (EGF), hepatocyte growth factor (HGF) and basic fibroblast growth factor (bFGF) at the ulcer margin, but the influence of EGF, HGF and bFGF applied locally with or without neutralizing anti-EGF, HGF and bFGF antibodies or cyclooxygenase (COX)-1 and COX-2 inhibitors on ulcer healing and the expression of COX-1 and COX-2 during ulcer healing have only been studied a little. METHODS Rats with gastric ulcers induced by serosal application of acetic acid (ulcer area 28 mm2 received a submucosal injection of either (1) vehicle (saline), (2) EGF, (3) HGF, and (4) bFGF with or without antibodies against EGF, HGF and bFGF or indomethacin (2 mg/kg/day i.p.), a nonspecific inhibitor of COX, or NS-398 (10 mg/kg/day i.g.) and Vioxx (5 mg/kg/day i.g.), both highly specific COX-2 inhibitors. A separate group of animals with chronic gastric fistulas was also used to assess gastric secretion during ulcer healing with and without growth factors. Each growth factor and specific antibody against EGF, HGF and bFGF (100 ng/100 microl each) were injected just around the ulcer immediately after ulcer induction and this local injection was repeated on day 2 following anesthesia and laparotomy. On days 13 and 21, the ulcer area was determined by planimetry, gastric blood flow (GBF) at the ulcer margin was examined by the H2-gas clearance technique, and mucosal generation of PGE2 and the gene expression of COX-1 and COX-2 in the non-ulcerated and ulcerated gastric mucosa were assessed. Gastric ulcers healed progressively within 21 days after induction and this effect was accompanied by a significant increase in GBF at the ulcer margin and in the expression of COX-2 in the ulcer area. Local treatment with EGF, HGF and bFGF produced a significant decrease in gastric acid secretion and significantly accelerated the rate of ulcer healing and raised GBF at the ulcer margin causing further significant upregulation of COX-2 but not COX-1 expression in the ulcerated mucosa. The acceleration of ulcer healing and hyperemia at the ulcer margin exhibited by locally applied EGF, HGF and bFGF were similar to those obtained with systemic administration of these growth factors. HGF applied submucosally, upregulated COX-2 expression and this was significantly attenuated by concurrent treatment with antibody against this peptide. Anti-EGF and anti-bFGF antibodies completely abolished the acceleration of the ulcer healing and hyperemia at the ulcer margin induced by these growth factors. Indomethacin and both COX-2 inhibitors significantly prolonged ulcer healing, while suppressing the generation of PGE2 in non-ulcerated and ulcerated gastric mucosa and GBF at the ulcer margin. The acceleration of ulcer healing by EGF, HGF and bFGF and the accompanying rise in GBF at the ulcer margin were significantly attenuated by the concurrent treatment with indomethacin or NS-398 and Vioxx. CONCLUSIONS (1) Growth factors accelerate ulcer healing due to enhancement in the microcirculation around the ulcer and these effects are specific because they can be abolished by neutralization with antibodies; (2) COX-2-derived prostaglandins and suppression of gastric secretion may play an important role in the acceleration of ulcer healing by various growth factors, and (3) the local effects of EGF, HGF and bFGF on ulcer healing can be reproduced by their systemic application indicating the high efficacy of growth factors to accelerate this healing.

Abstract
Multidimensional scaling (MDS) is introduced and discussed as a graphical method to complement conventional descriptive and confirmatory methods in the validation and analysis of quality of life (QOL) data. An outline of M DS as a statistical technique is given, and its application in the context of QOL research is described. The use of MDS is then illustrated in an example based on a study of 300 cancer survivors who completed the functional assessment of cancer therapy-general (FACT-G) and the EORTC core quality of life questionnaire (QLQ-C30). The correlational structure of the two widely used QOL instruments is investigated by means of MDS, and differences between the two questionnaires are elaborated. Finally, the merits and drawbacks of MDS are discussed in the specific context of the example and in the general framework of QOL research.

Abstract
Complex regional pain syndromes (formerly sympathetically maintained pain syndromes or reflex sympathetic dystrophy) encompass symptoms of pain, dysfunction and sympathetic disorder. They occur spontaneously or after peripheral or internal lesions (e.g. stroke or myocardial infarction) and predominantly affect the limbs, rarely the face or the trunk. This case report describes a 64-year old man who after a stroke suffered from heavy burning pain in the penis and perineum, which did not ameliorate after established conservative therapy. Sympathetic blockade, however, provided pain relief. The diagnosis of a complex regional pain syndrome, type I, was proposed according to the clinical symptoms in this patient, e.g. causalgia-like burning pain, allodynia, and the temporal association of an internal lesion to the onset of the pain. Other diagnoses such as neuropathic pain of unknown or diabetic etiology or a central post-stroke pain were considered.

Abstract
Recent studies have demonstrated that neutrophils have the capacity to produce a variety of cytokines after stimulation. The synthesis and release of prostaglandin E2 (PGE2) via the cyclooxygenase (COX) pathway has been reported to occur in activated neutrophils. In the present study, we sought to determine the status of COX protein synthesis and PGE2 production in murine neutrophils after burn injury. The effect of burn injury on neutrophil COX and PGE2 response to infection or lipopolysaccharide (LPS) was also examined. Peritoneal neutrophils were obtained from BDF1 mice at 4, 18, 24, and 36 hours after a 15% TBSA full-thickness scald burn or sham burn. We found that neutrophils from healthy mice express a low level of COX-2 protein. Neutrophil COX-2 protein expression in burn animals was significantly increased at 4 hours and dramatically decreased at 36 hours after burn injury. Animals 36 hours after burn and topically infected with Pseudomonas Aeruginosa had neutrophil COX-2 expression almost identical to burn injury only. Neutrophils harvested from healthy mice cocultured with LPS (1 microg/ml) had a marked induction of COX-2 protein. Neutrophils 24 hours after burn were unresponsive to LPS-stimulated COX-2 enhancement. COX-1 protein was strongly expressed constitutively and not affected further by burn injury or LPS. The production of PGE2 corresponded with the changes in COX-2 expression for all groups of mice. Our data suggested that neutrophils express both COX-1 and COX-2 and produce PGE2. The effects of burn injury on neutrophil COX-2 protein synthesis and PGE2 production suggest that after burn there is a time-dependent response. Insights into not only the global cellular response to injury and infection but also temporal nature of the response are important in the development of the therapeutic treatment strategies for burn patients.

Abstract
The F18 fimbriae expressed by porcine toxigenic Escherichia coli strains are 1- to 2-mm-long filaments that mediate the adhesion of the bacteria to enterocytes. The backbone of these fimbriae is built from a major structural 15.1-kDa protein, FedA. The structure of isolated negatively stained F18 fimbriae imaged by dark-field scanning transmission electron microscopy (STEM) was resolved to approximately 2 nm. Analyzing their helical symmetry showed the axially repeating units to alternate in a "zigzag" manner around the helical axis with an axial rise of 2.2 nm. Two repeating units give rise to the observed 4.3-nm helical repeat, which is practically identical to the pitch of the one-start helix formed. Additionally, an axially repeating pattern with a 27-nm spacing was found on rotary-shadowed fimbriae. Mass-per-length determination of unstained F18 fimbriae by STEM revealed the axially repeating unit to have a molecular mass of 25.4 kDa, indicating that it is a FedA monomer, with the difference in mass arising from the minor subunits, FedE and FedF. The presence of the latter two proteins might cause the observed 27-nm axial pattern.

Abstract
The ESVEM Trial evaluated methods to guide antiarrhythmic drug use in patients with spontaneous, inducible sustained tachyarrhythmias at electrophysiologic testing and frequent ventricular premature complexes (VPCs) per hour (>/=10). We assessed the relation between location (in-hospital or out-of-hospital) and classification of death (arrhythmic, nonarrhythmic, cardiac and/or noncardiac) for 486 randomized patients. Deaths were classified as out-of-hospital arrhythmic deaths if arrhythmic death occurred out-of-hospital, or if an arrhythmia preceded hospital admission and directly caused death. Of the 486 randomized patients, 188 (39%) died during 6 years of follow-up. The location and type of death could be determined clearly in 171 patients (91%). Ninety-one deaths were in-hospital (53%); 80 were out-of-hospital (47%). Arrhythmic deaths occurred in 85% out-of-hospital patients and in 30% in-hospital patients (p <0.001). Baseline characteristics were comparable for patients with out-of-hospital and in-hospital arrhythmic deaths. Twenty-seven of 95 arrhythmic deaths occurred in-hospital (28%); 72% occurred out-of-hospital. Out-of-hospital arrhythmic death accounted for 40% of deaths for which location and type of information were available. The 1- and 4-year actuarial out-of-hospital arrhythmic death rates were 9% and 18%, respectively. Of nonarrhythmic cardiac deaths, 91% were in-hospital and 9% were out-of-hospital. Of noncardiac deaths, 74% were in-hospital and 26% were out-of-hospital. Similar results were seen in the 296 patients for whom a drug was considered to be effective. Thus, over half the deaths in the ESVEM trial occurred in-hospital. The long-term actuarial risk of out-of-hospital arrhythmic death in ESVEM was unexpectedly low.

Abstract
BACKGROUND & AIM New class of nitric oxide-releasing non-steroidal anti-inflammatory drugs was shown to inhibit cyclooxygenase and prostaglandin generation without causing mucosal damage but whether these agents are capable of affecting gastric mucosal damage induced by strong irritants and healing of chronic gastric ulcers remains to be studied. In this investigation, effects of nitric oxide-releasing aspirin and nitric oxide-releasing naproxen were compared with those of native agents on gastric lesions provoked by 100% ethanol and on healing of chronic acetic acid ulcers. RESULTS Both, nitric oxide-releasing aspirin and naproxen dose-dependently attenuated ethanol-induced damage and produced a significant rise in gastric blood flow but did not delay healing of gastric ulcers while native aspirin and naproxen had no influence on ethanol-induced gastric damage but significantly prolonged ulcer healing, reduced gastric blood flow and suppressed mucosal generation of prostaglandin E2. The gastroprotective and hyperaemic effects of both nitric oxide-non-steroidal anti-inflammatory drugs were completely abolished by ODQ, an inhibitor of guanylyl cyclase-cGMP system but not influenced by suppression of nitric oxide-synthase with L-NNA. The damaging effects of native acetyl salicylate acid or naproxen were aggravated by acidification of these non-steroidal anti-inflammatory drugs but the exogenous acid added to nitric oxide-acetyl salicylate acid or nitric oxide-naproxen failed to influence their effect. Despite inhibiting of PGE2 generation, both nitric oxide-releasing derivatives and native aspirin and naproxen failed to affect expression of cyclooxygenase-1 mRNA but upregulated the cyclooxygenase-2 mRNA. Concurrent inhibition of cyclooxygenase-2 by selective inhibitor NS-398 which by itself delayed ulcer healing and attenuated the gastric blood flow at ulcer margin, significantly worsened the effects of these nitric oxide-non-steroidal anti-inflammatory drugs and their parent drugs on ulcer healing and the gastric blood flow at the ulcer margin. CONCLUSIONS 1) Coupling of nitric oxide to aspirin or naproxen attenuates ethanol-induced damage, possibly due to an increase in gastric microcirculation mediated by excessive release and action of nitric oxide that probably compensates for PG deficiency induced by non-steroidal anti-inflammatory drugs; and 2) nitric oxide-non-steroidal anti-inflammatory drug, unlike classic non-steroidal anti-inflammatory drugs, does not affect intact gastric mucosa and fails to delay the healing of pre-existing ulcers.

Abstract
Pediatric perineal impalement injuries are relatively uncommon. There may be difficulty in recognizing or properly treating such injuries, because their severity may not be reflected accurately by the external appearance of the perineum. The authors describe 3 case reports of patients with perineal impalement injuries and their management. The authors emphasize how a thorough workup can prevent missed injuries, leading to timely surgical repair and good outcomes.
