RESUMO

BACKGROUND: Necrotizing soft tissue infections (NSTIs) are life-threatening surgical emergencies associated with high morbidity and mortality. Fungal NSTIs are considered rare and have been largely understudied. The purpose of this study was to study the impact of fungal NSTIs and antifungal therapy on mortality after NSTIs. METHODS: A retrospective chart review was performed on patients with NSTIs from 2012 to 2018. Patient baseline characteristics, microbiologic data, antimicrobial therapy, and clinical outcomes were collected. Patients were excluded if they had comfort care before excision. The primary outcome measured was in-hospital mortality. RESULTS: A total of 215 patients met study criteria with a fungal species identified in 29 patients (13.5%). The most prevalent fungal organism was Candida tropicalis (n = 11). Fungal NSTIs were more prevalent in patients taking immunosuppressive medications (17.2% versus 3.2%, P = 0.01). A fungal NSTI was significantly associated with in-hospital mortality (odds ratio, 3.13; 95% confidence interval, 1.16-8.40; P = 0.02). Furthermore, fungal NSTI patients had longer lengths of stay (32 d [interquartile range, 16-53] versus 19 d [interquartile range, 11-31], P < 0.01), more likely to require initiation of renal replacement therapy (24.1% versus 8.6%, P = 0.02), and more likely to require mechanical ventilation (64.5% versus 42.0%, P = 0.02). Initiation of antifungals was associated with a significantly lower rate of in-hospital mortality (6.7% versus 57.1%, P = 0.01). CONCLUSIONS: Fungal NSTIs are more common in patients taking immunosuppressive medications and are significantly associated with in-hospital mortality. Antifungal therapy is associated with decreased in-hospital mortality in those with fungal NSTIs. Consideration should be given to adding antifungals in empiric treatment regimens, especially in those taking immunosuppressive medications.

RESUMO

Over a period of 5 mo, seven out of eight American white pelicans (Pelecanus erythrorhynchos) housed on a spring-fed pond at a zoo died or were euthanized. Clinical signs included inability to stand, anorexia, and weight loss. Clinicopathologic findings included heterophilic leukocytosis and elevated creatine kinase and aspartate aminotransferase. Histopathologic findings on all pelicans demonstrated severe, chronic, diffuse rhabdomyofiber degeneration and necrosis, making vitamin E deficiency a differential diagnosis despite routine supplementation. Based on tissue and pond water assays for the cyanobacterial toxin, microcystin, toxicosis is suspected as the inciting cause of death in these cases. We hypothesize that vitamin E exhaustion and resultant rhabdomyodegeneration and cardiomyopathy were sequelae to this toxicosis.

RESUMO

Cerebral radiation necrosis (CRN) is a known complication of radiation therapy. Treatment options are limited and include steroids, bevacizumab, and surgery. This study seeks to determine the safety of laser interstitial thermal therapy (LITT) for CRN and identify the pattern of post-ablation volume change over time. Patients undergoing LITT for tumor treatment at Henry Ford Hospital between November 2013 and January 2016 with biopsy-confirmed CRN were prospectively collected and retrospectively reviewed with attention to ablation volume, survival, demographic data, steroid dose, and complications. Imaging occurred at set intervals beginning pre-ablation. Ten patients with 11 ablations were evaluated. Four patients had a primary diagnosis of high-grade glioma, while six had metastatic lesions. An average of 86% of CRN volume was ablated. Ablation volume increased to 430% of initial CRN volume at 1-2 weeks before decreasing to 69% after 6 months. No patient had a decline in baseline neurological examination while in the hospital. Four patients developed delayed neurological deficits likely due to post-operative edema, of which three improved back to baseline. The 6-month survival was 77.8% and the 1-year survival was 64.8% based on Kaplan-Meier curve estimates. In this study, LITT was a relatively safe treatment for CRN, providing both a diagnostic and therapeutic solution for refractory patients. Significant increase in ablation volume was noted at 1-2 months, gradually decreasing in size to less than the original volume by 6 months. Further studies are needed to better define the role of LITT in the treatment of CRN.

RESUMO

BACKGROUND: The INFECT project aims to advance our understanding of the pathophysiological mechanisms in necrotizing soft tissue infections (NSTIs). The INFECT observational study is part of the INFECT project with the aim of studying the clinical profile of patients with NSTIs and correlating these to patient-important outcomes. With this protocol and statistical analysis plan we describe the methods used to obtain data and the details of the planned analyses. METHODS: The INFECT study is a multicentre, prospective observational cohort study. Patients with NSTIs are enrolled in five Scandinavian hospitals, which are all referral centres for NSTIs. The primary outcomes are the descriptive variables of the patients. Secondary outcomes include identification of factors associated with 90-day mortality and amputation; associations between affected body part, maximum skin defect and Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score and 90-day mortality; 90-day mortality in patients with and without acute kidney injury (AKI) and LRINEC score of six and above or below six; and association between affected body part at arrival and microbiological findings. Exploratory outcomes include univariate analyses of baseline characteristics associations with 90-day mortality. The statistical analyses will be conducted in accordance with the predefined statistical analysis plan. CONCLUSION: Necrotizing soft tissue infections result in severe morbidity and mortality. The INFECT study will be the largest prospective study in patients with NSTIs to date and will provide important data for clinicians, researchers and policy makers on the characteristics and outcomes of these patients.

RESUMO

A disease with white spots in internal organs of Nile tilapia occurred in Zhanjiang, southern China. Multiple, white nodules, 0.8-2.2 mm in diameter, were scattered throughout the liver, spleen and kidney of diseased fish. Signs of nodules reproduced after artificial infection with the isolated strain. Isolated bacteria were Gram-negative, facultative anaerobic, motile, short rod-shaped, with a length of 1.2-2.2 µm. Morphological and biochemical tests, as well as phylogenetic analysis, all strongly indicated that the isolate from tilapia is identical to Aeromonas schubertii (A. schubertii) which temporary named LF1708 strain. Antibiotic sensitivity assays showed the LF1708 is sensitive to 24 of 27 tested antibiotics. Pathogenicity test revealed that the isolate at the dose of 3.75 × 106 CFU/g killed 100% of experimental tilapia within 2 days and the dose of 1 × 107 CFU/g killed 100% of experimental zebrafish within 1 day. Histopathology of diseased tilapia infected with A. schubertii showed numerous necrotic lesions widely distributed in spleen, liver and kidney, and infiltration with a large number of bacteria. To our knowledge, this was the first report that associated A. schubertii with mortality in tilapia.

RESUMO

Tumor necrosis (TN) can lower responsiveness to chemotherapy and confer basic resistance to anti-cancer therapy. We investigated the association of TN with poor clinical features and outcome in diffuse large B cell lymphoma (DLBCL). We examined the presence or absence of TN in 476 DLBCL patients of who received rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy. Eighty-nine (18.7 %) patients had TN at diagnosis. Patients with TN had a progression-free survival (PFS) and overall survival (OS) of 39.3 and 46.7 %, whereas patients without TN had a PFS and OS of 73.4 and 82.6 %. Adverse clinical factors of poor Eastern Cooperative Oncology Group performance status ≥ grade 2 (p = 0.005), elevated lactate dehydrogenase ratio >1 (p < 0.001), advanced Ann Arbor stage (p = 0.002), and bulky disease (p = 0.026) were more prevalent in the TN group than the non-TN group. Cox regression model analysis revealed TN as an independent prognostic factor for PFS and OS in DLBCL (PFS, hazard ratio [HR] = 1.967, 95 % confidence interval [CI] = 1.399-2.765, p < 0.001; OS, HR = 2.445, 95 % CI = 1.689-3.640, p < 0.001). The results indicate that TN could reflect adverse clinical features and worse prognosis in DLBCL patients receiving R-CHOP therapy.

RESUMO

Herpesviral haematopoietic necrosis (HVHN), caused by cyprinid herpesvirus-2 (CyHV-2), has affected the commercial production of the goldfish Carassius auratus and gibelio carp Carassius auratus gibelio. High water temperature treatments are reported to reduce the mortality rate of infected goldfish and elicit immunity in the survivors. To define the mechanism by which this intervention induces resistance, clonal ginbuna Carassius auratus langsdorfii, which is closely related to both species and has been used in fish immunology, may represent a promising model species. In this study, we investigated the susceptibility of clonal ginbuna strains to CyHV-2 and the effect of high water temperature treatment on infected ginbuna and goldfish. Experimental intraperitoneal infection with CyHV-2 at 25 °C caused 100% mortality in ginbuna strains, which was accompanied by histopathological changes typical of HVHN. Both infected ginbuna S3n strain and goldfish, exposed to high temperature for 6 days [shifting from 25 °C (permissive) to 34 °C (non-permissive)], showed reduced mortalities after the 1st inoculation, and subsequent 2nd virus challenge to 0%, indicating induction of immunity. It was concluded that ginbuna showed a similar susceptibility and disease development in CyHV-2 infection compared to goldfish, suggesting that ginbuna can be a useful fish model for the study of CyHV-2 infection and immunity.

RESUMO

BACKGROUND: Pediatric adnexal torsion is rare, can be challenging to recognize, and may result in ovarian loss. OBJECTIVE: We sought to identify and compare the defining characteristics of adnexal torsion in premenarchal and postmenarchal girls. METHODS: A retrospective cohort study was performed at a tertiary care children's hospital, including patients diagnosed postnatally with adnexal (ovarian or tubal) torsion between 1997 and 2013. Proportions were compared using relative risk regression. RESULTS: Adnexal torsion was found in 59 premenarchal and 43 postmenarchal girls. Abdominal pain was the most common chief complaint (54%). History included reports of pain (96%), vomiting (67%), and fever (19%). Excluding 12 patients with isolated tubal torsion and 19 with a teratoma, there were no statistically significant differences in ovarian loss in premenarchal vs. postmenarchal girls (47% and 25% respectively; relative risk [RR] = 1.8 [95% confidence interval {CI} 0.9-3.8]), left- vs. right-sided torsion (47% and 32%; RR = 1.5 [95% CI 0.8-2.7]), pain duration ≤ 2 days vs. > 2 days (31% and 41%; RR = 0.8 [95% CI 0.4-1.5]; n = 64) and severe pain vs. mild to moderate (38% and 33%; RR = 1.1 [95% CI 0.7-1.5]; n = 56). CONCLUSIONS: The diagnosis of pediatric adnexal torsion is difficult and often delayed. Pain and tenderness may not be isolated to a unilateral lower quadrant. Although traditionally considered a postmenarchal problem, in a pediatric academic emergency department adnexal torsion occurred with similar frequency in premenarchal and postmenarchal girls. The potential for organ salvage means that adnexal torsion should be considered in all females presenting with acute abdominal pain regardless of age or menstrual history.

RESUMO

There were examined in dynamics 724 patients, in whom complicated diabetic foot syndrome (DFS) was diagnosed, and in 71 (9.8%) of them the disease was complicated by sepsis. The state severity in a DFS patients have depended upon duration of purulent-necrotic process on the foot, in septic patients such dependence was not revealed. All the DFS patients without sepsis were operated on. In total 36 died (lethality 5.5%), in presence of sepsis - 42 (lethality 59.1%). The cause of sepsis in the patients, suffering complicated DFS, was predominantly a wet gangrene of the lower extremities. Among those, who were not operated on, 13 (30.9%) septic patients died, of them 5 ­ who refused operative intervention performance - died in first hours after admittance to hospital due to irreversible injury of organs and systems.

RESUMO

PURPOSE: We aimed to investigate clinical features of patients with descending necrotizing mediastinitis (DNM) in order to improve management and outcome. METHODS: We prospectively examined all patients with DNM admitted to the Intensive Care Unit (ICU) during the period from April 2007 to December 2013. Demographics, clinical features, microbiology, medical and surgical treatment data were recorded. Survivor and nonsurvivor groups were analyzed to identify factors associated with mortality. RESULTS: Overall, 34 patients with DNM have been included. The mean age was 46.8 ± 11.2 years (range 24-70). The male/female ratio was 3.25. DNM arose from odontogenic infection in 22 (65%) patients; from peritonsillar abscess in 9 (26%) patients and from paranasal sinus in 3 (9%) patients. Microbiological cultures revealed a high percentage of aerobic/anaerobic coinfection. Nonsurvivors were statistically more likely to have higher SAPS II score (mean difference 19.1, 95% CI 12.3-25.9 P < 0.01) and more severe disease (P < 0.01) than survivors. Positive correlation was found between time to ICU admission after head or neck infection diagnosis and SAPS II score (ρ = 0.5, P = 0.03). The same was true for ICU length of stay and time to ICU admission (ρ = 0.6, P < 0.01) and time to surgery (ρ = 0.5, P = 0.03). Surgical treatments consisted in: transcervical drainage in 14 cases, (42%); irrigation through subxiphoid and cervical incisions of the anterior mediastinum with additional percutaneous thoracic drainage when necessary in ten cases, (29 %); thoracotomy with radical mediastinal surgical debridement, excision of necrotic tissue and decortication in ten cases, (29%). We have found a mortality rate of 12%. Patients with DNM type IIB were admitted to the ICU later than patients with DNM type I and type IIA (mean difference 3.2 days, 95% CI 1.2-5.1, P 0.02). CONCLUSIONS: Prompt ICU admission in order to manage severe sepsis and/or septic shock, along with early and aggressive surgery and adequate antimicrobial therapy, could be key factors in reducing DNM mortality.

RESUMO

Lake trout Salvelinus namaycush (Walbaum) raised for stocking experienced yearly (2011-13) winter epizootics of epitheliocystis. Affected fish were dispersed on the bottom of the tank, had decreased feed and fright response, and mortality often reached 40%. Peak mortality occurred within 3 weeks of the appearance of clinical signs, and outbreaks typically lasted 6 weeks. Affected fish had no gross lesions but histologically had branchial epithelial necrosis and lamellar hyperplasia, with small to large numbers of scattered epithelial cells containing 10- to 20-µm inclusions. A longitudinal study was undertaken of one annual outbreak, and lamellar hyperplasia was most closely associated with mortality. The number of inclusions was statistically greater (P < 0.05) before and during peak mortality, but inclusions were present in low numbers before clinical signs occurred. Results of histochemical staining, immunohistochemistry and transmission electron microscopy supported the presence of a ß-proteobacteria rather than a Chlamydiales bacterium within inclusions. PCR primers to identify Chlamydiales did not give consistent results. However, the use of universal 16S rDNA bacterial primers in conjunction with laser capture microdissection of inclusions demonstrated that a ß-proteobacteria was consistently associated with affected gills and is more likely the cause of the disease in lake trout.

RESUMO

The analysis of changes in the specific immunity in patients with purulent­necrotic complications of diabetic foot syndrome (DFS) and sepsis was presented. Complicated DFS was diagnosed in 436 patients, of whom 29 (6.6%) ­ weighed down by sepsis. The concentration of the major classes of immunoglobulins IgA, IgM, IgG were determined by enzyme­linked immunosorbent assay (ELISA). To evaluate the immune state was determined lymphocyte subpopulations (CD4+, CD3+, CD8+, CD25+) with monoclonal antibodies to antigens use by flow cytometry. It was found that in patients with DFS indicators specific cellular immunity were in a state of suppression, which deepened at complication of sepsis. Based on the derived formula with DFS marked disorders of the immune system I degree, in sepsis ­ II degree. Thus, the cellular and humoral immune system in patients with both DFS and sepsis qualified as a general immune depression.

RESUMO

Retrospective analysis of 108 observation files of 66 patients, operated on for chronic pancreatitis complications and 42 ­ for postnecrotic pancreatic cysts, using draining, resection­draining and resection operations, was conducted. Morphological changes in pancreatic parenchyma and pancreatic postnecrotic cysts at the operation time were compared with intraoperative blood loss, rate and character of intraoperative and post/ operative complications, depending on the kind, duration, volume and adequacy of the operations performed, as well as with lethality rate. Disadvantages in surgical treatment were noted in 57 (57%) patients, and 4 (3.7%) patients died. Unsuccessful surgical treatment in 64.9% observations was caused by incapacity to perform an adequate surgical intervention, the anastomosis sutures insufficiency, postoperative hemorrhage and significant intraoperative blood loss

RESUMO

BACKGROUND/AIMS: Though end-stage renal disease (ESRD) is increasingly attributed to acute tubular necrosis (ATN), contemporary trends in the rates of incidence and recovery of renal function are poorly defined. Hence, we set out to describe the clinical epidemiology of ESRD due to ATN between 2001 and 2010. METHODS: We examined United States Renal Data System data (n = 1,070,490) for 2001 through 2010 to calculate the incidence rates and rates of renal recovery and death for patients with ESRD due to ATN treated with renal replacement therapy (RRT, n = 27,603). RESULTS: Standardized incidence ratios increased between 2001-2002 and 2009-2010 in the overall population (ratio 2.14), having risen in all demographic subgroups examined. Recovery of renal function was more likely in patients with ATN than in matched controls (cumulative incidence 23% vs. 2% at 12 weeks, 34% vs. 4% at 1 year), as was death (cumulative incidence 38% vs. 27% at 1 year). Hazards ratios for renal recovery increased stepwise with year of RRT inception to 1.34 (95% confidence interval 1.24-1.45) for 2009-2010 (vs. 2001-2002). In contrast, hazards ratios for death declined stepwise to 0.83 (0.79-0.87) in 2009-2010. CONCLUSION: While the incidence of ESRD attributed to ATN has increased, prospects of renal recovery and survival have also increased. Despite substantial mortality risk on RRT, renal recovery is not a rare occurrence.

RESUMO

Bone marrow necrosis (BMN) is characterized by infarction of the medullary stroma, leading to marrow necrosis with preserved cortical bone. In reported small series, BMN in hematological malignancies is associated with poor prognosis. We sought to find the impact of BMN on clinical outcome in a relatively larger cohort of patients with acute leukemias. Overall we evaluated 1,691 patients; 1,051 with acute myeloid leukemia (AML) and 640 with acute lymphocytic leukemia referred to our institution between 2002 and 2013. Patients with AML and acute lymphoblastic leukemia (ALL) were evaluated separately to determine the incidence of BMN, associated clinical features and its prognostic significance. At initial diagnosis, BMN was observed in 25 (2.4%) patients with AML and 20 (3.2%) patients with ALL. In AML, BMN was significantly associated with French-American-British AML M5 morphology (32% vs. 10%, P = 0.002). The complete remission (CR) rate in AML with and without BMN was 32% and 59% respectively (P = 0.008). Likewise, CR rate in ALL with BMN was also inferior, 70% vs. 92% (P = 0.005). The median overall survival (OS) in AML with BMN was significantly poorer, 3.7 months compared to 14 months without BMN (P = 0.003). Similarly, the median OS in ALL with and without BMN was 61.7 and 72 months respectively (P = 0.33). BMN is not a rare entity in AML and ALL, but is infrequent. BMN in AML and in ALL is suggestive of inferior response and poor prognosis.

RESUMO

In November 2007, the container ship Cosco Busan released 54,000 gallons of bunker fuel oil into San Francisco Bay. The accident oiled shoreline near spawning habitats for the largest population of Pacific herring on the west coast of the continental United States. We assessed the health and viability of herring embryos from oiled and unoiled locations that were either deposited by natural spawning or incubated in subtidal cages. Three months after the spill, caged embryos at oiled sites showed sublethal cardiac toxicity, as expected from exposure to oil-derived polycyclic aromatic compounds (PACs). By contrast, embryos from the adjacent and shallower intertidal zone showed unexpectedly high rates of tissue necrosis and lethality unrelated to cardiotoxicity. No toxicity was observed in embryos from unoiled sites. Patterns of PACs at oiled sites were consistent with oil exposure against a background of urban sources, although tissue concentrations were lower than expected to cause lethality. Embryos sampled 2 y later from oiled sites showed modest sublethal cardiotoxicity but no elevated necrosis or mortality. Bunker oil contains the chemically uncharacterized remains of crude oil refinement, and one or more of these unidentified chemicals likely interacted with natural sunlight in the intertidal zone to kill herring embryos. This reveals an important discrepancy between the resolving power of current forensic analytical chemistry and biological responses of keystone ecological species in oiled habitats. Nevertheless, we successfully delineated the biological impacts of an oil spill in an urbanized coastal estuary with an overlapping backdrop of atmospheric, vessel, and land-based sources of PAC pollution.

RESUMO

BACKGROUND: Breast cancer is the second most common source of brain metastasis. Stereotactic radiosurgery (SRS) can be an effective treatment for some patients with brain metastasis (BM). Necrosis is a common feature of many brain tumors, including BM; however, the influence of tumor necrosis on treatment efficacy of SRS in women with breast cancer metastatic to the brain is unknown. METHODS: A cohort of 147 women with breast cancer and BM treated consecutively with SRS over 10 years were studied. Of these, 80 (54.4%) had necrosis identified on pretreatment magnetic resonance images and 67 (46.4%) did not. Survival times were computed using the Kaplan-Meier method. Log-rank tests were used to compare groups with respect to survival times, Cox proportional hazards regression models were used to perform univariate and multivariate analyses, and chi-square and Fisher exact tests were used to compare clinicopathologic covariates. RESULTS: Neurological survival (NS) and survival after SRS were decreased in BM patients with necrosis at the time of SRS compared with patients without necrosis by 32% and 27%, respectively (NS median survival, 25 vs 17 months [log-rank test, P = .006]; SRS median survival, 15 vs 11 months [log-rank test, P = .045]). On multivariate analysis, HER2 amplification status and necrosis influenced NS and SRS after adjusting for standard clinical features, including BM number, size, and volume as well as Karnofsky performance status. CONCLUSION: Neuroimaging evidence of necrosis at the time of SRS significantly diminished the efficacy of therapy and was a potent prognostic marker.

RESUMO

BACKGROUND AND PURPOSE: Cardiac injury is common after subarachnoid hemorrhage (SAH) and is associated with adverse early outcomes, but long-term effects are unknown. The first aim of this study was to compare the long-term rates of death, stroke, and cardiac events in SAH survivors versus a matched population without SAH. The second aim was to quantify the effects of cardiac injury on the outcome rates. METHODS: This was a retrospective cohort study of patients with and without non-traumatic SAH. For aim #1, the predictor variable was SAH and the outcome variables were all-cause and cerebrovascular mortality, stroke, cardiac mortality, acute coronary syndrome (ACS), and heart failure (HF) admission. A multivariable Cox proportional hazards analysis was performed. For aim #2, the predictor variables were cardiac injury (elevated serum cardiac enzymes or a diagnosis code for ACS) and dysfunction (pulmonary edema on X-Ray or a diagnosis code for HF). RESULTS: Compared with 4,695 members without SAH, the 910 SAH patients had higher rates of all-cause mortality (hazard ratio [HR 2.6], 95% confidence intervals [CI] 2.0-3.4), cerebrovascular mortality (HR 30.6, CI 13.5-69.4), and stroke (HR 10.2, CI 7.5-13.8). Compared with the non-SAH group, the SAH patients with cardiac injury had increased rates of all-cause mortality (HR 5.3, CI 3.0-9.3), cardiac mortality (HR 7.3, CI 1.7-31.6), and heart failure (HR 4.3, CI 1.53-11.88). CONCLUSIONS: SAH survivors have increased long-term mortality and stroke rates compared with a matched non-SAH population. SAH-induced cardiac injury is associated with an increased risk of death and heart failure hospitalization.

RESUMO

Experiments on rats with myocardium infarction showed that intravenous administration of etoxidol in a dose of 14.2 mg/kg restricted the size of necrosis area and reduced the ratio of necrosis/ischemia zones. The test compound reduced the risk of rhythm and conduction disturbances induced by administration of toxic epinephrine doses to the mice, and increased mouse survival. Etoxidol administered intravenously to cats with acute myocardial ischemia reduced epinephrine concentration and intensity of free radical oxidation in zones of myocardial lesions against the background of the increase in norepinephrine concentration and antioxidant activity in the myocardium. By antiischemic and antioxidant activity, etoxidol was superior to its structural analogue mexidol.
