Risk factors for mortality in fournier's gangrene in a general hospital: use of simplified founier gangrene severe index score (SFGSI)

ABSTRACT Objective To evaluate risk factors for mortality in patients with Fournier's gangrene (FG), with emphasis in the Simplified Fournier Gangrene Severe Index Score (SFGSI). Materials and Methods This was a cross-sectional study that was carried out from January 2010 to December 2014, with 124 patients treated for FG in a General Hospital. Several clinical and laboratory variables, including SFGSI, were evaluated and correlated with mortality through univariate analysis and logistic regression. Results Of the 124 patients, 99 were men (79.8%), the mean age was 50.8±19.5 years and the main comorbidity was diabetes mellitus (51.6%). The mortality rate was 25.8%. Variables that presented independent correlation with mortality were the extension of the lesion to the abdomen (OR=4.0, CI=1.10-14.68, p=0.03), hematocrit (OR=0.81, CI=0.73-0.90, p<0.0001), potassium (OR=2.41, CI=1.13-5.10, p=0.02) and creatinine (OR=2.15, CI= 1.04-4.41, p=0.03). When hematocrit, potassium and creatinine were tested together, as part of the SFGSI, a >2 result was the largest of the independent predictors of mortality (OR=50.2; CI=13.18-191.47; p<0.0001). Conclusion The SFGSI >2 presented a higher correlation with mortality than any variable tested alone. It seems to be a promising alternative to evaluate predictors of mortality in Fournier's gangrene. The main advantage is easy applicability because it contains only three parameters and can be used immediately after patient's admission.

Use of photodynamic inactivation for in vitro reduction of prevalent bacteria in Fournier's Gangrene

ABSTRACT Fournier's Gangrene (FG) is an infectious disease caused by several synergic microbes, with high morbidity and mortality rates; therefore, the search for new less invasive and mutilating treatments, with faster recovery, has been proposed. Surgical intervention, the use of several systemic and topic antibiotics, and hyperbaric oxygen therapy are currently the best approach for the treatment of these patients. The use of Photodynamic Inactivation (PDI) aims to lower morbidity and mortality, by reducing bacterial microbiota and speeding wound healing. In the present study, viable bacteria were separated in four groups: Group L-/F- (no irradiation with red laser and absence of methylene blue photosensitizer), Group L-/F+ (no irradiation with red laser and presence of methylene blue), Group L+/F- (irradiation with red laser and absence of methylene blue) and L+/F+ (irradiation with red laser associated to methylene blue). In all groups, exposure time to treatment was 5, 10 and 15 minutes. The concentration of methylene blue photosensitizer was 0.1mg/L, and the dose of red laser (660nm wave length) was 176.9mW/cm2. Following irradiation, the reduction of number of bacteria was evaluated, and the results were expressed in colony forming units (CFU) and as exponential reduction. As the main results, in the L+/F+ group, there were no Clostridium perfringens and Staphylococcus aureus CFUs and there was a reduction of Escherichia coli that was not observed in the other groups.

Diagnóstico y manejo precoz de la gangrena de fournerr / Early diagnosis and management of fournier´s gangrene

Aim: The aim of this study is to report the results of a series of patients diagnosed with Fournier’s gangrene underwent surgical debridement plus broad-spectrum antibiotics in the emergency department of the Hospital Barros Luco-Trudeau (HBLT) between 2009 and 2013, in terms of mortality associated with the disease. Material and Methods: Between 2009 and 2013, a case series of patients with diagnosis of Fournier’s gangrene treated in the Emergency Department of the Hospital Barros Luco-Trudeau. The outcome variable was mortality attributed to the disease (MAD). Other variables were: age, sex, comorbidities, focus of origin, waiting time for antibiotic treatment and surgery to start, number of surgical debridement and agents isolated from cultures. Descriptive statistics were used, with calculation of measures of central tendency and dispersion. Results: During the study period, 56 patients were identified with diagnosis of Fournier’s gangrene (60.7 percent were male) with a mean age of 52 years (23-75 years old). The MAD was 48.2 percent. The most common comorbidity was diabetes (66.6 percent). The more prevalent focus of origin was anorectal pathology (42.9 percent). The average waiting time from diagnosis to initiation of antibiotic therapy and surgery was 40 minutes (15-80) and 580 minutes (20-4320), respectively. The required surgical debridement average was 4. Isolated on the intraoperative tissue cultures agent was E. coli (51.8 percent). Conclusion: Mortality attributable to Fournier’s gangrene is similar to that observed in the literature.

Fournier's gangrene in Mansoura Egypt: a review of 74 cases.

BACKGROUND: Fournier's gangrene (FG), caused by synergistic aerobic and anaerobic organisms, is a life-threatening disorder in which infection of the perineum and scrotum (can affect penis alone) spreads along fascial planes, leading to soft-tissue necrosis. Despite antibiotics and aggressive debridement, the mortality rate of FG remains high. MATERIALS AND METHODS: We analyzed 74 patients admitted to our institution's emergency surgical unit presenting with FG between January 2002 and January 2007, considering the anatomical site of infective gangrene, predisposing factors, etiological agents, and outcomes. RESULTS: All the 74 patients included in this study were males; their mean age was 51+/-10.8 years (21-72 years). The mean duration from the onset of symptoms to admission to the hospital was 3.74+/-2.09 days (1-8 days). The mean hospitalization time was 9.2+/- 6.6 days (1-31). Forty patients (54.05%) had FG secondary to anorectal conditions. No etiologic factors for FG were found in 27 patients (36.5%). Diabetes mellitus as a predisposing factor was found in 38 patients (51.35%). There was no definite predisposing factor in 24 patients (32.43%). The microbiological finding was polymicrobial in 48 patients (64.8%) and monomicrobial in 26 patients (35.1%). The most frequent bacterial organisms were Escherichia coli (75.6%). Simple sigmoid loop colostomy was done in one patient (1.4%). Unilateral orchidectomy was done in one case (1.4%). The overall mortality rate was 16 patients (21.6%). CONCLUSION: FG is a rapidly progressive, fulminant infection. Even with aggressive surgical and medical treatment, mortality of the disease is high. In the present cases, such a high ratio of 21.6% means that this disease is still serious and fatal in Egypt.

Fournier gangrene. Approaches to diagnosis and treatment

To investigate the factors associated with patients with Fournier's gangrene, and to clarify the effect of diabetes mellitus [DM] as a comorbid disease on morbidity and mortality of patients with Fournier's gangrene. Twenty-six Fournier's gangrene patients who were admitted to the Emergency Department of Ankara Numune Teaching and Research Hospital, Ankara, Turkey from 1997 to 2003 were examined retrospectively. The mean age of the patients was 52.8 years. There were 8 female [30.8%] and 18 male [69.2%] patients. The etiological causes were as follows: diseases of the perianal region, history of operations, trauma and injections. Major comorbid disease states were diabetes mellitus [DM] and hypertension. The lesions in Fournier's gangrene were most commonly located in the perineum and genital region. Female patients with diabetes mellitus had significantly unusual extensive involvement, especially abdominal wall involvement. The most frequently isolated pathogen was Escherichia coli, while staphylococcal infection was most commonly seen in the presence of DM. Colostomy was performed on 53.8% of the patients, and cystostomy on 7.6% of the patients. Average time of staying at the hospital was 25 days with a mortality rate of 34.6%. Patients with DM had high mortality rates and stayed longer at the hospital than the non-diabetic patients. In addition to early diagnosis, early and aggressive debridement and administration of multiple wide spectrum antibiotics chosen for the causative agent are the golden standard for decreasing the mortality and morbidity. Diabetes mellitus has been found to be an important factor to increase mortality rates of patients with Fournier's gangrene
