Abstract
Vesicles prepared from block copolymers have been mooted for the encapsulation of water-soluble molecules. This is because the membranes of polymer vesicles have been shown to be more stable than those in vesicles formed from lipids, with the membrane properties being tuned by the length and nature of the hydrophobic block in the polymer. The generally accepted mechanisms of vesicle formation involve either wrap-up of a lamellar sheet or formation via a sequence of micelle to worm to disks to vesicles. These should lead to efficient encapsulation. Alternatively, a method involving phase separation followed by re-structuring has been recently suggested. Here, we show that this final mechanism holds for vesicles formed from a PEO-b-PDEAMA copolymer by a pH switch and that this mechanism leads to highly inefficient encapsulation on vesicle formation.

Abstract
BACKGROUND Human leucocyte antigen (HLA) antibodies have been implicated in transfusion-related acute lung injury, but the probability that the transfusion of a blood component containing HLA antibodies will cause a reaction is not known. This study compared the prevalence of reactions associated with the transfusion of platelet components with and without HLA antibodies. STUDY DESIGN AND METHODS This retrospective study tested 96 consecutive apheresis platelet donors for HLA class I and II antibodies. Matched control donors without HLA antibodies were selected and records were reviewed to determine the proportion of components from each group that caused reactions. In addition, all apheresis platelet donors involved with two or more reactions were identified and tested for HLA class I antibodies. RESULTS Five of the 96 donors had antibodies to class I or class II antigens and, of these, four had components transfused. The prevalence of reactions to components from these four donors with HLA antibodies and the 12 matched control donors without antibodies was similar (three reactions to 167 transfusions or 1.8% vs. three to 295 or 1.0%, respectively, P = 0.32). A retrospective review of the transfusion records from all platelet donors found that components from 22 caused two or more reactions and three (13.6%) had antibodies to HLA class I compared to 4.2% of the consecutively selected donors (P = 0.12). None of the patients experienced transfusion-related acute lung injury. CONCLUSION Reactions associated with transfusion of apheresis platelets containing HLA antibodies are unusual.

Abstract
Enterococcal isolates (n = 102) from various sources of bovine origin on 1 farm were characterized using pulsed field gel electrophoresis analysis of SmaI restriction patterns. Isolates originated from feed samples (n = 6), bedding samples (n = 15), and bovine quarter-milk samples (n = 81). Isolates collected from milk samples included those from high-somatic cell count cows (n = 42), postpartum milk samples (n = 16), and clinical mastitis samples (n = 23). Species evaluated included Enterococcus faecium (n = 68), Enterococcus casseliflavus (n = 29), and Enterococcus faecalis (n = 5). A total of 20 clusters representing 44 isolates were detected when a similarity cut-off level of 75% was applied to interpret the pulsed field gel electrophoresis results. Fifteen of the clusters contained only isolates from milk samples. Four clusters contained isolates from bedding and milk samples. One cluster contained only isolates from feed samples. Clusters comprised of a single species represented 17 of the 20 total clusters. These results suggest enterococci from bovine origin were genetically diverse, whereas a limited number of isolates from various sources appeared to cluster together.

Abstract
Genotyping is useful to predict the expression of those RBC antigens for which antisera are difficult to obtain and to determine the probable phenotype of highly transfused patients, and it can be used to test stored DNA when a blood sample is not available. This study assessed a sequence-specific primer (SSP)-based genotyping system for blood group alleles suitable for the rapid testing of a small number of samples and assessed the use of stored whole blood. Genomic DNA was isolated from fresh and 1- and 2-week-old stored blood from 20 donors with known ABO and Rh phenotypes and was used for ABO, RHD, and RHCE genotyping using SSPs. The amplicons were analyzed using gel electrophoresis and a novel microfluidic on-chip electrophoresis system. Analysis of DNA from fresh and 1- and 2-week-old blood by SSP and gel electrophoresis yielded the correct ABO, RHD, and RHCE type in all samples, but with DNA from 2-week-old stored blood the amplicons were more difficult to visualize. Analysis of the same samples with the SSP on-chip electrophoresis assay correctly typed all samples except for one RHCE typing discrepancy of a fresh sample and one RHCE typing discrepancy of a 2-week-old sample. Analysis of amplicons by on-chip electrophoresis required one tenth the DNA that gel electrophoresis did and could be completed within 30 minutes compared with 2 hours with gel electrophoresis. Amplicons were also more readily visualized with on-chip electrophoresis. Fresh and 1- and 2-week-old samples could be ABO and RH genotyped with SSP. Analysis using on-chip electrophoresis was easier and more rapid than that using gel electrophoresis, but test reliability was slightly more variable.

Abstract
Natural killer (NK) cells are the first lymphocytes to recover after allogeneic stem cell transplantation (SCT) and can exert powerful graft-versus-leukemia (GVL) effects determining transplant outcome. Conditions governing NK cell alloreactivity and the role of NK recovery in sibling SCT are not well defined. NK cells on day 30 post-transplant (NK30) were measured in 54 SCT recipients with leukemia and donor and recipient killer immunoglobulin-like receptor (KIR) genotype determined. In univariate analysis, donor KIR genes 2DL5A, 2DS1, 3DS1 (positive in 46%) and higher numbers of inhibitory donor KIR correlated with higher NK30 counts and were associated with improved transplant outcome. NK30 counts also correlated directly with the transplant CD34 cell dose and inversely with the CD3+ cell dose. In multivariate analysis, the NK30 emerged as the single independent determinant of transplant outcome. Patients with NK30 >150/microl had less relapse (HR 18.3, P=0.039), acute graft-versus-host disease (HR 3.2, P=0.03), non-relapse mortality (HR 10.7, P=0.028) and improved survival (HR 11.4, P=0.03). Results suggest that T cell-depleted SCT might be improved and the GVL effect enhanced by selecting donors with favorable KIR genotype, and by optimizing CD34 and CD3 doses.

Abstract
8545 Purpose: This clinical trial evaluates the safety and adjuvant activity of imiquimod, a toll-like receptor (TLR)-7 agonist, when given with a NY-ESO-1 protein vaccine. Imiquimod, by locally activating and recruiting dendritic cells (DCs) into the skin, is expected to stimulate antigen uptake by DCs, induce maturation and migration to draining lymph nodes, and to induce antigen-specific T and B cell immunity. Methods: Pilot study; 9 patients with resected stage 2B-3C malignant melanoma. Four 21 day cycles consisted of topical imiquimod cream (250 mg) on days 1–5 and id. injected NY-ESO-1 protein (100 mcg) into the site on day 3. Blood was drawn at several time points for immune monitoring; skin punch biopsies were obtained from control, imiquimod and vaccination sites 48 hours after the last vaccination. Results: The regimen was tolerated well, all patients completed four vaccinations. AEs were mild and transient and included injection site reactions (8/9 patients), fatigue (4/9 patients) and fever (2/9 patients). Significant levels of antigen-specific CD4+ or CD8+ T cell responses were not detected in ex-vivo ELISPOT assays. However, intracellular cytokine staining assays after in vitro pre-stimulation indicated that 6 of 8 subjects developed NY-ESO-1 CD4+ T cell responses. Humoral immunity was manifest by the induction of anti-NY-ESO-1 antibodies in 7/9 patients post-vaccination. Histochemistry of skin sections showed significant dermal mononuclear cell infiltrates in Imiquimod treated skin, whereas none were seen in untreated skin (p<0.01). IHC revealed markedly increased numbers of CD3+ (T-cells), CD68+ (macrophages/monocytes), CD123+ (plasmacytoid DCs) and DC-LAMP+ (mature myeloid DCs) immune cells in Imiquimod treated skin when compared with control skin of the same patients (p<0.05). Conclusion: Imiquimod, a topical immune response modifier, generated clear inflammatory infiltrates in the dermis, with significant increases in antigen-presenting cells and T cells. Imiquimod was well tolerated when used as an adjuvant to an NY-ESO-1 protein vaccine. Systemic immunity of both humoral and cellular types was induced in the majority of patients; however, responses were weak and the vaccine combination needs to be optimized in future studies. No significant financial relationships to disclose.

Abstract
Chronic non-communicable diseases such as epilepsy, diabetes, cardiac disease and hypertension represent a growing but neglected burden in developing countries. Rural sufferers, distant from health facilities, bear this most acutely. In response, a community care programme has been developed at Jimma University Hospital and its allied health centres in rural southwest Ethiopia. This involves general duty nurses at rural health centres being trained to provide care for chronic disease patients, with regular supervision from the hospital physicians. The programme allows treatment to be provided away from the main hospital so that those who cannot afford to travel can access care near their homes. Improved access increases the request for care, and helps to address the large unmet need for chronic disease treatment. This is a good model in which rural healthcare delivery through a team can bring widespread benefit. In this article chronic disease care is discussed with a particular focus on diabetes and epilepsy. The model can be replicated in more or less developed countries and may also be relevant for HIV care.

Abstract
On 3 February 2004, the Vermont Department of Health received reports of acute gastroenteritis in persons who had recently visited a swimming facility. A retrospective cohort study was conducted among persons attending the facility between 30 January and 2 February. Fifty-three of 189 (28%) persons interviewed developed vomiting or diarrhoea within 72 h after visiting the facility. Five specimens tested positive for norovirus and three specimen sequences were identical. Entering the smaller of the two pools at the facility was significantly associated with illness (RR 5.67, 95% CI 1.5-22.0, P=0.012). The investigation identified several maintenance system failures: chlorine equipment failure, poorly trained operators, inadequate maintenance checks, failure to alert management, and insufficient record keeping. This study demonstrates the vulnerability of recreational water to norovirus contamination, even in the absence of any obvious vomiting or faecal accident. Our findings also suggest that norovirus is not as resistant to chlorine as previously reported in experimental studies. Appropriate regulations and enforcement, with adequate staff training, are necessary to ensure recreational water safety.

Abstract
Experimental and theoretical investigations of the swelling and mechanical properties of hydrogels formed from chitosan, bovine serum albumin (BSA), and chitosan/BSA mixtures cross-linked with genipin were performed. The properties of cross-linked chitosan hydrogels were explained in terms of its polyelectrolyte behavior, which led to a gradual increase in swelling ratio below the pK value, but whereby its swelling ability was eliminated by the presence of salt that screened the charges. Comparison of theoretical and experimental calculations of the swelling ratio, however, indicated that complications arising from wastage of cross-links, and formation of polymerized genipin cross-links must be considered before quantitative prediction can be achieved. Cross-linked BSA hydrogels swelled even in the presence of salt, and a marked increase in swelling was observed below pH = 3 that was explained as the result of an acid induced denaturation of the protein that led to unfolding of the molecule. Swollen BSA hydrogels were mechanically weak, however. Composite gels made from a cross-linked mixture of chitosan and BSA exhibited the swelling behavior of BSA combined with the mechanical properties of chitosan and were therefore considered most suitable for use in a gastric environment.

Abstract
In 1991, the Somali National Movement fighters recaptured the Somaliland capital city of Hargeisa after a 3-year civil war. The government troops of the dictator General Mohamed Siad Barre fled south, plunging most of Somalia into a state of anarchy that persists to this day. In the north of the region, the redeclaration of independence of Somaliland took place on May 18, 1991. Despite some sporadic civil unrest between 1994 and 1996, and a few tragic killings of members of the international community, the country has enjoyed peace and stability and has an impressive development record. However, Somaliland continues to await international recognition. The civil war resulted in the destruction of most of Somaliland's health-care facilities, compounded by mass migration or death of trained health personnel. Access to good, affordable health care for the average Somali remains greatly compromised. A former medical director of the general hospital of Hargeisa, Abdirahman Ahmed Mohamed, suggested the idea of a link between King's College Hospital in London, UK, and Somaliland. With support from two British colleagues, a fact-finding trip sponsored by the Tropical Health and Education Trust (THET) took place in July, 2000, followed by a needs assessment by a THET programme coordinator. Here, we describe the challenges of health-care reconstruction in Somaliland and the evolving role of the partnership between King's College Hospital, THET, and Somaliland within the context of the growing movement to link UK NHS trusts and teaching institutions with counterparts in developing countries.

Abstract
AIM This study assesses the effects of the reconfiguration of postgraduate surgical training and changes to work patterns through legislation within UK on the operative experience of trainees completing specialty training in paediatric surgery. METHODS Data were collected from the consolidation record of operative experience submitted by every candidate sitting the Intercollegiate Specialty Board Examination in Paediatric Surgery in UK from 1996 through 2004. A number of index procedures were chosen as surrogates of the overall operative experience and underwent detailed analysis. These comprised operations performed in the following categories: Neonatal Surgery, General Paediatric Surgery, Paediatric Urology, Paediatric Oncology, and Emergency Paediatric Surgery. RESULTS Sixty-three sets of data comprising 12,866 operations were ultimately identified as being suitable for analysis. The average number of operations performed annually by trainees increased over the study period as did the number in each of the operative categories. The number of operations performed with senior assistance or supervision increased over this period by an average of 12.5%. This trend was also evident in emergency surgery where the average number of sample procedures performed by trainees increased by 28% over the study period. CONCLUSION In 1995, reforms to the training grade within UK reduced the time spent in specialist training from a previously unregulated period to 72 months of higher surgical training. Subsequent directives in response to health and safety legislation have further abbreviated the length of time spent at the workplace, initially to 72 hours and more recently to 58 hours per week. This combination has been generally perceived throughout the surgical community as prejudicial to acquisition of clinical and operative competence. This study, however, fails to endorse this perception and suggests to the contrary that perhaps through increased delegation, the volume of training operations is being preserved and that operative training is now better supervised than ever before.

Abstract
BACKGROUND This descriptive study evaluates the impact on endometrial development of standard and high doses of a GnRH antagonist in stimulated cycles compared with GnRH agonist and natural cycles. METHODS Thirty-one oocyte donors were treated with a combination of rFSH and 0.25 mg/day ganirelix (standard dose), 2 mg/day ganirelix (high dose) or 0.6 mg/day buserelin (long protocol). Vaginal progesterone (200 mg/day) was administered in the luteal phase. Endometrial biopsies were performed 2 and 7 days after HCG administration. Additional biopsies were carried out in a subset of 12 subjects, 2 and 7 days following the LH peak of their previous natural cycle. Biopsies were evaluated histologically and by scanning electron microscopy. Gene expression profiles were also studied. RESULTS At HCG +2, all the parameters studied were similar in all the groups and comparable to those observed in the natural cycle. At HCG +7, endometrial dating, steroid receptors and the presence of pinopodes were comparable in both GnRH antagonist groups and in the natural cycle. In buserelin group, endometrial dating and pinopode expression suggested an arrested endometrial development. For window of implantation genes, expression patterns were closer to those in the natural cycle following standard- or high-dose ganirelix than after buserelin administration. CONCLUSION No relevant alteration was observed in the endometrial development in the early and mid-luteal phases in women undergoing controlled ovarian stimulation for oocyte donation following daily treatment with a standard- or high-dose GnRH antagonist. In addition, the endometrial development after GnRH antagonist mimics the natural endometrium more closely than after GnRH agonist.

Abstract
PURPOSE Evaluation of different parameters of contrast media enhancement for the differentiation between scar tissue and local recurrence of rectal cancer. MATERIALS AND METHODS We included 83 patients after operation and radiotherapy of rectal cancer. In total, 20 local recurrences were diagnosed. After administration of 75 ml Iopromide (370 mg/ml) and a delay of 65 s, the whole abdomen and pelvis were scanned in a collimation of 4 x 2.5 mm and 12.5 mm table feed per rotation. The suspected tissue was marked by the freehand ROI option in every slice and the minimum, average and maximum densities were calculated. A local recurrence was suspected if maximum density was higher than 90 HU after admission of contrast media. In addition we calculated the maximum difference of density as the difference between maximum and minimum density. RESULTS The minimum and average densities showed no reliable differences for patients with or without local recurrence (minimum density 4 HU ( +/- 12 HU) vs. 13 HU ( +/- 21 HU), P = 0.23, average density 48 HU ( +/- 10 HU), vs. 48 HU ( +/- 17 HU)), P = 0.52. The patients suffering from local recurrence showed higher maximum densities and a higher maximum difference than the patients without recurrence (maximum density 111 HU ( +/- 13 HU) vs. 81 HU ( +/- 24 HU), P = 0.02, maximum difference 103 HU ( +/- 20 HU) vs. 76 HU ( +/- 31 HU), P = 0.06. These differences were not significant. We calculated a sensitivity of 0.6, a specificity of 0.83, a positive predictive value of 0.52 and an accuracy of 0.77. CONCLUSION It is not possible to diagnose a recurrent rectal cancer by density values alone.

Abstract
Two percent of acute pancreatitis are drug induced. In the present paper, we reported the case of a 39 year-old patient with chronic-hallucinatory schizophrenia who developed symptomatic pancreatitis during the clozapine dose titration performed to reach the therapeutic range. Diagnosis of pancreatitis was suggested by clinical examination and abnormal laboratory values of pancreatic enzymes and confirmed by C-T scan and ultrasonography. The causal incrimination of clozapine in this case seems likely as all other possible causes of pancreatitis were excluded, as AP developed shortly after the introduction of the drug and as the pancreatic enzymes normalized after clozapine was stopped. No rechallenge to confirm the causal relationship was however attempted. So far, only eight cases of acute pancreatitis have been reported in association with clozapine use. Clozapine is an atypical antipsychotic drug which belongs to the chemical class of dibenzodiazepines. The mechanism by which clozapine could produce acute pancreatitis remained unclear. Nevertheless, we advocate a careful biological follow-up (measuring periodically the concentrations of amylase, lipase and triglycerides) during the treatment by clozapine.

Abstract
The association of multiple sclerosis with alleles/haplotypes from the HLA region on chromosome 6p21 is well established although the remainder of the genome remains relatively unexplored. We have completed a genome-wide screen for linkage disequilibrium in a cohort of Australian multiple sclerosis patients positive for HLA-DRB1*1501. A total of 4346 microsatellite markers provided through the "Genetic Analysis of Multiple sclerosis in EuropeanS" (GAMES) collaborative were analysed in DNA separately pooled from cases (n=217) and controls (n=187). Associations were found in four genomic regions (12q15, 16p13, 18p11 and 19q13) previously identified in linkage genome screens. Three additional regions of novel association were also identified (11q12, 11q23 and 14q21). Further analysis of these regions is required to establish whether the associations observed are due to epistatic interaction with the HLA locus.

Abstract
Juvenile hyaline fibromatosis (JHF) and infantile systemic hyalinosis (ISH) are autosomal recessive conditions characterized by multiple subcutaneous skin nodules, gingival hypertrophy, joint contractures, and hyaline deposition. We previously mapped the gene for JHF to chromosome 4q21. We now report the identification of 15 different mutations in the gene encoding capillary morphogenesis protein 2 (CMG2) in 17 families with JHF or ISH. CMG2 is a transmembrane protein that is induced during capillary morphogenesis and that binds laminin and collagen IV via a von Willebrand factor type A (vWA) domain. Of interest, CMG2 also functions as a cellular receptor for anthrax toxin. Preliminary genotype-phenotype analyses suggest that abrogation of binding by the vWA domain results in severe disease typical of ISH, whereas in-frame mutations affecting a novel, highly conserved cytoplasmic domain result in a milder phenotype. These data (1) demonstrate that JHF and ISH are allelic conditions and (2) implicate perturbation of basement-membrane matrix assembly as the cause of the characteristic perivascular hyaline deposition seen in these conditions.

Abstract
Despite improvements in chemotherapy and the recognition that aggressive surgical cytoreduction is beneficial, the majority of patients diagnosed with ovarian cancer will die as a result of metastatic disease. The molecular changes associated with acquisition of metastatic ability in ovarian cancer are poorly understood. We hypothesize that metastasis suppressor gene inactivation or down-regulation plays a role in ovarian cancer progression. Mitogen-activated protein kinase kinase 4 (MKK4), a member of the stress-activated protein kinase signaling cascade, has been identified recently as a metastasis-suppressor gene. An immunohistochemical approach was taken to test the possibility that MKK4 dysregulation occurs during the development of clinical ovarian cancer metastases. MKK4 expression was evaluated in normal and metastatic ovarian tissues. Normal ovarian epithelial cells showed high intensity staining for MKK4, whereas metastatic tissues showed a statistically significant decrease in expression. These results support a role for MKK4 dysregulation in the development of clinical disease. A functional approach was taken to test the ability of MKK4 to suppress metastatic colonization, the process whereby disseminated cancer cells lodge and grow at a secondary site in vivo. The SKOV3ip.1 human ovarian cancer cell line was chosen for these studies because it lacks endogenous MKK4 expression but retains both upstream and downstream components of the signaling cascade of MKK4. Ectopic expression of MKK4 in these cells, when injected into female SCID mice, suppressed the number of overt metastatic implants by nearly 90%. Furthermore, MKK4 expression increased the life span of the animals by 70%. Taken together, these data support a role for MKK4 in the suppression of metastatic colonization in ovarian cancer.

Abstract
INTRODUCTION Preservation-reperfusion injury is a major cause of graft failure after liver transplantation. This injury refers to a variety of insults after reperfusion of the graft, independent of technical errors, vascular problems, immunological reactions or infection. Significant injuries occur during the period of cold preservation. Loss of sinusoidal endothelial attachments to the underlying extracellular matrix results in loss of the normal antithrombogenic milieu. Reperfusion with recipient blood results in platelet aggregation and neutrophil sludging in all areas of denudation, preventing adequate reoxygenation. Early histopathological findings in biopsy specimens can predict poor graft outcome. OBJECTIVE To analyse the effect of early rearterialisation on histological findings of the liver biopsies after liver transplantation. METHODS Twenty young Large White X Landrace pigs (weight 22-28 kg) were subjected to orthotopic liver transplantation. Livers were stored in Eurocollins solution for 3 hours on ice and the animals were randomised into four different groups of increasingly early arterialisation. Groups were aligned from delayed rearterialisation (group 1) to early rearterialisation (group 4). Biopsies were taken before and after cold storage, as well as 1 hour post transplantation. RESULTS Results show that both hepatocyte vacuolisation and neutrophil infiltration were significantly reduced in group 4 (early rearterialisation), compared with groups 1, 2 and 3. Single cell necrosis and group cell necrosis of the hepatocytes were both significantly reduced in groups 3 and 4 compared with groups 1 and 2 (early venous reperfusion). CONCLUSION This study demonstrates that early rearterialisation is associated with a decrease in early histopathological changes in the transplanted pig liver.

Abstract
BACKGROUND Client or consumer expectation is considered to influence their satisfaction with the service provided, but its importance has not been quantified in health care. OBJECTIVE The aim of this study was to determine the effect of "patient expectations of care" on satisfaction with care provided by out-of-hours services. METHODS We surveyed 3457 patients who requested out-of-hours care from five practices, two general practice out-of-hours co-operatives and a deputizing service in an English health authority during late 1997. The independent variables were: the service providing the care (service type), where out-of-hours care was given (location of care) and whether the care met the patient's expectations. The independent variable was overall patient satisfaction with out-of-hours care. RESULTS Patients who received the care they hoped for (their idealized expectation was met) were more satisfied than those who did not. Patients who attended centres were more satisfied with the care received than those who had had home visits. Patients were more satisfied if they received care from the co-operative which did not employ assistants than from the deputizing service. Idealized expectation (care which was hoped for) match, location of care and service type explained 34, 2 and 4% of the variance, respectively. Age, sex, ethnicity, access to a car, normative/comparative expectation (care which was expected) and whether patients expected and received telephone advice, a home visit or domiciliary care, and the delay between request for care and care provision were not independently associated with satisfaction. CONCLUSIONS Meeting or failing to meet the care patients hoped for is an important predictor of patient satisfaction with out-of-hours care. Purchasers and providers of out-of-hours care should consider whether and how patient expectation of service can be managed. This may reduce patient dissatisfaction with the service they provide. These findings also have important implications for the design of studies which use patient satisfaction as an outcome variable.

Abstract
Post-transplant lymphoproliferative disorders (PTLD) are a well recognised complication of conventional haemopoietic stem cell transplantation (HSCT). Reduced intensity HSCT involves intensive immunosuppression to permit engraftment. Thirty reduced intensity transplants with the FBC (fludarabine 150 mg/m2, busulphan 8 mg/m2, CAMPATH-1H 100 mg) protocol have been performed at our centre, with one confirmed EBV-positive PTLD. The female recipient developed a perforated viscus day +191 following HSCT from a volunteer unrelated male donor. A large caecal mass and a retroperitoneal abscess were excised, revealing an EBV-positive diffuse large B cell lymphoma confirmed by FISH to be of donor origin. More experience is required before the risk of PTLD in this setting can be assessed.

Abstract
Magnetic resonance imaging and ultrasound are the imaging modalities recommended in the early diagnosis of Fournier's gangrene. Because of the high mortality of this inflammatory disease early diagnosis is essential to initiate adequate surgical and medical treatment. In the clinical literature only a handful of cases, in which diagnosis of Fournier's gangrene is based on MRI findings, have been reported; therefore, we report another case which shows the ability of MRI especially to determine the point of origin and extension of disease.
