ClearSpeechTogether: a Rater Blinded, Single, Controlled Feasibility Study of Speech Intervention for People with Progressive Ataxia.

BACKGROUND: Progressive ataxias frequently lead to speech disorders and consequently impact on communication participation and psychosocial wellbeing. Whilst recent studies demonstrate the potential for improvements in these areas, these treatments generally require intensive input which can reduce acceptability of the approach. A new model of care-ClearSpeechTogether-is proposed which maximises treatment intensity whilst minimising demands on clinician. This study aimed to establish feasibility and accessibility of this approach and at the same time determine the potential benefits and adverse effects on people with progressive ataxias. METHOD: This feasibility study targeted people with progressive ataxia and mild-moderate speech and gross motor impairment. ClearSpeechTogether consisted of four individual sessions over 2 weeks followed by 20 patient-led group sessions over 4 weeks. All sessions were provided online. Quantitative and qualitative data were collected for evaluation. RESULTS: Nine participants completed treatment. Feasibility and acceptability were high and no adverse effects were reported. Statistical tests found significantly reduced vocal strain, improved reading intelligibility and increased participation and confidence. Participant interviews highlighted the value of group support internalisation of speech strategies and psycho-social wellbeing. DISCUSSION: ClearSpeechTogether presented a feasible, acceptable intervention for a small cohort of people with progressive ataxia. It matched or exceeded the outcomes previously reported following individual therapy. Particularly notable was the fact that this could be achieved through patient led practice without the presence of a clinician. Pending confirmation of our results by larger, controlled trials, ClearSpeechTogether could represent an effective approach to manage speech problems in ataxia.

Sensitizing the interdisciplinary team to desensitizations: An alemtuzumab case report.

INTRODUCTION: We describe a case of alemtuzumab (Campath®) hypersensitivity requiring desensitization within the medical intensive care unit (MICU) in a patient with T-cell prolymphocytic leukemia. CASE REPORT: We adopted a desensitization protocol from Gutierrez-Fernandez et al., which included three aliquots (0.15 mg intravenously (IV), 1.5 mg IV, and 28.5 mg IV) given approximately 1 h apart on day 1 followed by a full 30 mg dose IV on day 3. Unlike prior attempts to administer alemtuzumab to this patient, she tolerated the medication well and did not require any rescue medications. MANAGEMENT AND OUTCOME: Successful plan development required a significant amount of strategic communication between hematology/oncology and MICU-related physicians, pharmacists, and nurses to ensure a safe and effective desensitization. The first step of planning required creation of a desensitization order set with directions for medication preparation and administration, premedications, and available medications in the event of an adverse reaction or anaphylaxis. Anaphylactoid-related medications were prepared at bedside and ready for administration prior to beginning the desensitization. Alemtuzumab was compounded in a chemotherapy-certified hood and verified by at least two chemotherapy-certified pharmacists. Foreword planning was also necessary to ensure multiple people were available or present at bedside for the desensitization, including a chemotherapy-certified nurse, a second chemotherapy-certified nurse for verification, a critical care-certified pharmacist, a pulmonary/critical care attending physician, and hematology attending physician. DISCUSSION: This case exemplifies the importance of clear and coordinated communication between different healthcare fields to safely and effectively complete extensive protocols such as desensitization strategies.

Comparison of Hip and Knee Arthroplasty Rates of Individuals With and Without Prader-Willi Syndrome.

BACKGROUND: Prader-Willi syndrome (PWS) is a complex genetic condition, affecting between 1:10,000 and 1:30,000. The prevalence of hip dysplasia in children with PWS is reportedly between 8% and 30%, but the long-term consequences of residual hip dysplasia remain largely unknown in this population. The purpose of this study was to comparatively estimate the number of total hip arthroplasty (THA) and total knee arthroplasty (TKA) procedures performed on adults with and without PWS, using a national hospital discharge database, in an effort to elucidate long-term outcomes and guide clinicians treating orthopaedic concerns in younger individuals with PWS. METHODS: The National Inpatient Sample of the Healthcare Cost and Utilization Project is the largest all-payer inpatient care database, containing annual data from >7 million hospital stays; sampling weights and stratification variables are provided for producing estimates of >35 million hospitalizations nationwide. THA and TKA procedures were identified, then stratified by whether or not the patient had a diagnosis of PWS. The ages of the 2 groups and sex mix were compared, as was the length of stay for the procedure, and discharge status. RESULTS: From 2004 to 2014, 9.4 million patients nationwide, by weighted estimate, underwent THA (3.1 million) or TKA (6.3 million). Sixty-five patients were identified as having the diagnosis of PWS (39 with THA, 26 with TKA); 7 patients per million having hip or knee arthroplasties had PWS. Sixty-eight percent of those with PWS were younger than 50 years, compared with only 7% of those without PWS (P<0.001). The female:male prevalence was 47:53 for patients with PWS and 60:40 for the total group. The mean length of stay was similar, but patients with PWS were more likely to be transferred to another facility after surgery (77% vs. 36%; P=0.008). CONCLUSIONS: Hip dysplasia prevalence is higher in persons with PWS, but the rate of late treatment with THA is much lower than in the general population. We recommend only active observation for stable and improving hips in young children with PWS, as the consequences of overtreatment can be serious, including further delaying their neuromuscular development, and exposure to possibly unnecessary perioperative risks. LEVEL OF EVIDENCE: Nation-wide database analysis, Level IV.

Anti-thymocyte globulin in haematology: Recent developments.

Anti-thymocyte globulin (ATG) is a polyclonal antiserum introduced into clinical medicine more than 30 years ago. It induces a broad non-specific immunosuppression. In haematology, standard indications are severe aplastic anaemia and prophylaxis and treatment of graft-versus-host disease (GVHD) (after allogeneic transplantation). For aplastic anaemia, ATG from horses has been found to be superior to ATG from rabbits. In the situation of allogeneic transplantation, ATG lessens the risk of chronic GVHD but may not improve survival. There is current controversy regarding which patients benefit most from ATG and what the ideal dosage is. It is likely that in the coming years a more specific immunosuppressive will be developed that will minimize GVHD while maintaining the graft-versus-malignancy effect.

Nephrotoxicity during Vancomycin Therapy in Combination with Piperacillin-Tazobactam or Cefepime.

Recent reports have demonstrated that vancomycin (VAN) may lead to an increase in the incidence of acute kidney injury (AKI) when it is combined with antipseudomonal beta-lactams. This study compared the incidence of AKI associated with VAN plus piperacillin-tazobactam (TZP) or cefepime (FEP). This was a retrospective, matched cohort study that was conducted at an academic medical center between September 2010 and September 2014 and that included adult patients without severe chronic or structural kidney disease, dialysis, pregnancy, cystic fibrosis, or a hospital transfer receiving TZP-VAN or FEP-VAN for at least 48 h. The primary outcome was the difference in the AKI incidence between the TZP-VAN and FEP-VAN groups, evaluated using the risk, injury, failure, loss of kidney function, and end-stage kidney disease (RIFLE) criteria. Patients in the two groups were matched on the basis of age, sex, severity of illness, baseline creatinine clearance, hypotension, number of nephrotoxicity risk factors, and intravenous contrast exposure. In total, 4,193 patients met all inclusion criteria (3,605 received TZP-VAN and 588 received FEP-VAN). The unadjusted AKI incidence was 21.4% in patients receiving TZP-VAN, whereas it was 12.6% in patients receiving FEP-VAN (P < 0.001). After the patients were matched, 1,633 patients receiving TZP-VAN and 578 patients receiving FEP-VAN were evaluated. The AKI incidence remained higher in patients receiving TZP-VAN than in those receiving FEP-VAN (21.4% versus 12.5%, P < 0.0001). This trend remained true for all classifications of the RIFLE criteria. After controlling for remaining confounders, TZP-VAN therapy was associated with 2.18 times the odds of AKI than FEP-VAN therapy (95% confidence interval, 1.64 to 2.94 times) in logistic regression. AKI was significantly more common in patients receiving vancomycin in combination with piperacillin-tazobactam than in those receiving vancomycin in combination with cefepime. This finding reinforces the need for the judicious use of combination empirical antimicrobial therapy.

Cadmium attenuates the macrophage response to LPS through inhibition of the NF-κB pathway.

Chronic obstructive pulmonary disease (COPD) in the U.S. is primarily caused by cigarette smoking. COPD patients are highly susceptible to respiratory infections in part due to alveolar macrophage dysfunction despite a substantial increase in macrophages in the lung. Cadmium (Cd) is a toxic metal that is concentrated within tobacco and accumulates in the lung of smokers. We hypothesized that Cd uptake into macrophages alters immune function thereby impairing the macrophage response to invading pathogens. Our hypothesis was tested by comparing primary human monocytes and macrophages, primary mouse bronchoalveolar lavage myeloid cells, and related cell lines. Strikingly, Cd exposure followed by LPS stimulation resulted in a dose-dependent, significant decrease in nuclear p65 activity in macrophages that was not observed in monocytes. This corresponded with Cd-mediated inhibition of IKKß and an impaired ability to transcribe and release cytokines in response to LPS challenge in vivo. These findings provide novel evidence that Cd has the capacity to disrupt macrophage immune function compared with monocytes. Importantly, Cd results in immune dysfunction in macrophages through inhibition of the NF-κB signaling pathway. Based on these findings, we provide new evidence that Cd contributes to immune dysfunction in the lung of COPD subjects and may increase susceptibility to infection.

Intentional Adulteration of Foods with Chemicals: Snapshot for 2009-2022.

Global occurrences of the intentional adulteration of food with a chemical toxicant culled from the literature and news reports from 2009 to 2022 were analyzed in terms of their ability to cause mass public health harm. A total of 76 intentional adulteration events that involved over 27 chemicals and 16 foods were identified. The chemicals used included pesticides, rat poisons, illicit drugs, and commercial chemicals. A total of 253 deaths and 4,887 illnesses were attributed to intentional adulteration events; there were deaths in 20% and illnesses in 50% of the events. Intentional adulteration during manufacturing, which accounted for 21 events (28%), resulted in 205 deaths (81%) and 3,572 illnesses (73%). Intentional adulteration at the food preparation node, which accounted for 17 events (22%), resulted in 39 deaths (15%) and 387 illnesses (8%). On-farm intentional adulteration, eight events (10%) resulted in 843 illnesses (17%) and no deaths. The perpetrators who were identified generally had legitimate access to the food, although in 63% of the cases studied, the perpetrator was not identified. Economically motivated adulteration and revenge resulted in over 80% of the deaths and illnesses.

Transdiaphragmatic sarcomatoid carcinoma of the lung: A case report.

INTRODUCTION: Pulmonary sarcomatoid carcinoma is a very rare primary tumor of the lung. Although usually aggressive, these tumors have not been described previously to invade through the diaphragm into the liver. We present a patient with a pulmonary sarcomatoid carcinoma with transdiaphragmatic spread into the dome of the liver. PRESENTATION OF CASE: An 82-year-old female with a lifetime non-smoking history presented with generalized fatigue, fever, night sweats, cough, and pleuritic chest pain. She had recently traveled to the western United States. Additionally, she had recently undergone periodontal deep cleaning with no peri-procedural antibiotics. Laboratory testing was significant for a leukocytosis of 13.5 white blood cells per microliter and a negative viral panel. Computed tomography and magnetic resonance imaging revealed a large heterogeneous mass extending from the right pulmonary hilum through the diaphragm. Although initial radiology reports suggested hepatic abscess, percutaneous fine needle aspiration was performed. Biopsy revealed pulmonary sarcomatoid carcinoma. She was begun on systemic treatment. DISCUSSION: Pulmonary sarcomatoid carcinoma can exhibit transdiaphragmatic invasion into the liver. This clinical situation can easily be confused with a hepatic abscess, but suspicion should remain for abscess. Clinical suspicion for neoplasm should warrant biopsy when technically possible. CONCLUSION: Although hepatic abscesses can exhibit transdiaphragmatic spread into the chest, pulmonary sarcomatoid carcinoma can also invade the abdomen. Biopsy should be performed during the evaluation and workup of the patient.

Successful Visceral and Parietal Pericardiectomy for Refractory Effusive-Constrictive Pericarditis: A Challenging Case Report.

BACKGROUND Effusive-constrictive pericarditis (ECP) is an uncommon clinical syndrome characterized by the coexistence of pericardial effusion and constriction involving the visceral pericardium. This differs from constrictive pericarditis, which presents with thickening of the pericardium without effusions. Specific diagnostic criteria of ECP include the failure of right atrial pressure to decrease by 50% or reach a new level below 10 mmHg after normalization of intrapericardial pressure. CASE REPORT We present the case of a 32-year-old obese man with multiple comorbidities who initially presented with flu-like symptoms and pleural effusion with development of constrictive-like symptoms. Despite undergoing numerous pericardiocentesis and appropriate medical management, the patient's condition failed to improve, leading to the likely diagnosis of effusive-constrictive pericarditis. Cultures of pericardial fluid revealed E. -faecium, which required multiple antimicrobial therapy. Despite infection, the exact etiology of ECP remained unknown and likely idiopathic. Common causes of ECP include idiopathic, tuberculosis, cardiac surgery complications, radiation, or neoplasia. Ultimately, the patient underwent a pericardiectomy involving the visceral and parietal pericardium, resulting in hemodynamic stability and resolution of symptoms. CONCLUSIONS This case highlights the challenges in diagnosing and managing ECP, emphasizing the importance of considering surgical intervention in refractory cases. ECP initially presents as a pericardial effusion, often addressed through pericardiocentesis; however, in a small subset of patients, sustained symptoms and altered hemodynamics persist following pericardiocentesis, necessitating further evaluation and management. The success of pericardiectomy in our patient highlights the potential efficacy of surgical intervention in improving outcomes for patients with ECP.

Spatial and spatio-temporal clusters of lung cancer incidence by stage of disease in Michigan, United States 1985-2018.

Lung cancer is the most common cause of cancer-related death in Michigan. Most patients are diagnosed at advanced stages of the disease. There is a need to detect clusters of lung cancer incidence over time, to generate new hypotheses about causation and identify high-risk areas for screening and treatment. The Michigan Cancer Surveillance database of individual lung cancer cases, 1985 to 2018 was used for this study. Spatial and spatiotemporal clusters of lung cancer and level of disease (localized, regional and distant) were detected using discrete Poisson spatial scan statistics at the zip code level over the study time period. The approach detected cancer clusters in cities such as Battle Creek, Sterling Heights and St. Clair County that occurred prior to year 2000 but not afterwards. In the northern area of the lower peninsula and the upper peninsula clusters of late-stage lung cancer emerged after year 2000. In Otter Lake Township and southwest Detroit, late-stage lung cancer clusters persisted. Public and patient education about lung cancer screening programs must remain a health priority in order to optimize lung cancer surveillance. Interventions should also involve programs such as telemedicine to reduce advanced stage disease in remote areas. In cities such as Detroit, residents often live near industry that emits air pollutants. Future research should therefore, continue to focus on the geography of lung cancer to uncover place-based risks and in response, the need for screening and health care services.

Lung Cancer and Air Quality in a Large Urban County in the United States.

Lung cancer is the leading cancer-related killer in the United States. The incidence varies geographically and may be affected by environmental pollutants. Our goal was to determine associations within time series for specific air pollutants and lung cancer cases over a 33-year period in Wayne County, Michigan, controlling for population change. Lung cancer data for Wayne County were queried from the Michigan Cancer Registry from 1985 to 2018. Air pollutant data were obtained from the United States Environmental Protection Agency from 1980 to 2018. Autoregressive distributed lag (ARDL) models were estimated to investigate time lags in years between specific air pollution levels and lung cancer development. A total of 58,866 cases of lung cancer were identified. The mean age was 67.8 years. Females accounted for 53 percent of all cases in 2018 compared to 44 percent in 1985. Three major clusters of lung cancer incidence were detected with the most intense clusters in downtown Detroit and the heavily industrialized downriver area. Sulfur dioxide (SO2) had the strongest statistically significant relationship with lung cancer, showing both short- and long-term effects (lag range, 1-15 years). Particulate matter (PM2.5) (lag range, 1-3 years) and nitrogen dioxide (NO2) (lag range, 2-4 years) had more immediate effects on lung cancer development compared to carbon monoxide (CO) (lag range, 5-6 years), hazardous air pollutants (HAPs) (lag range, 9 years) and lead (Pb) (lag range, 10-12 years), which had more long-term effects on lung cancer development. Areas with poor air quality may benefit from targeted interventions for lung cancer screening and reductions in environmental pollution.

Resection of a giant thoracic solitary fibrous tumor treated with preoperative arterial coiling followed by a double-level thoracotomy.

Solitary fibrous tumor (SFT) are rare pleura neoplasms often localized to middle or inferior hemithorax. A middle-aged woman presents to the emergency department following a motor vehicle accident, the computed tomography scan revealed a giant tumor occupying the entire left pleural cavity with a complete collapse of the left lung and substantial right deviation of heart and mediastinum. Using preoperative arterial coiling followed by a double-level thoracotomy we successfully resected the giant tumor. The SFT weighed ~10 lbs. At 2-month follow-up visit patient reports mild discomfort during strenuous movement/heavy lifting but denies any shortness of breath.

Partner Cooperation, Conflict, Maternal Mental Health, and Parenting Behaviors in Rural Kenya: Towards a Two-Generational Understanding of Gender Transformation Benefits.

Increasing partner cooperation is an established approach to reducing intimate partner violence. This strategy, known in the literature as "gender transformation," benefits mental and physical health of women and men. Less is known about the potential for gender transformation strategies to improve the nurturing context for children. We hypothesize that increasing partner cooperation, a common benefit of community-based empowerment programs, would decrease child maltreatment through reducing intimate partner conflict and improving maternal mental health. This study utilizes cohort data from women (n = 400) participating in a combined group-based microfinance program to assess potential mechanisms by which partner cooperation at T1 (June 2018) predicts less children maltreatment at T2 (June 2019). As hypothesized, partner cooperation predicts less subsequent child maltreatment-frequency of neglect, corporal punishment, physical assault, and psychological abuse in the past month. This association is mediated completely by subsequent more partner cooperation and less intimate partner conflict, maternal loneliness, and depression. Implications of this study include potential for combining multiple development areas-women's empowerment, intimate partner cooperation, mental health, and child nurturing contexts. Future study should assess these pathways in a cluster-based randomized trial, and explore how findings may inform policy and practice where these domains are less integrated.

Treatment patterns and outcomes in patients with Pancoast tumors: a national cancer database analysis.

Background: Pancoast tumors represent 5% of non-small cell lung cancers. Complete surgical resection and no lymph node involvement are important positive prognostic factors. Previous literature has identified neoadjuvant chemoradiation treatment, followed by surgical resection, as the standard of care. But many institutions choose upfront surgery. Our goal was to identify the treatment patterns and outcomes in patients with node-negative Pancoast tumors using the National Cancer Database (NCDB). Methods: The NCDB was queried from 2004 through 2017 to identify all patients who had undergone surgery for a Pancoast tumor. Treatment patterns, including the percentage of patients who received neoadjuvant treatment, were recorded. Logistic regression and survival analyses were used to determine outcomes based on different treatment patterns. Secondary analyses were performed on the cohort who received upfront surgery. Results: A total of 2,910 patients were included in the study. Overall 30- and 90-day mortality were 3% and 7% respectively. Only 25% (717/2,910) of the group received neoadjuvant chemoradiation treatment prior to surgery. Patients who received neoadjuvant chemoradiation treatment experienced significantly improved 90-day survival (P<0.01) and overall survival (P<0.01). When analyzing the cohort who received upfront surgery, there was a statistically significant difference in survival based on adjuvant treatment pattern (P<0.01). Patients in this group who received adjuvant chemoradiation had the best survival, whereas patients who received adjuvant radiation only or no treatment had the worst outcomes. Conclusions: Patients with Pancoast tumors receive neoadjuvant chemoradiation treatment in only a quarter of cases nationally. Patients who received neoadjuvant chemoradiation treatment had improved survival compared to patients who had upfront surgery. Similarly, when surgery is performed first, adjuvant chemoradiation treatment improved survival compared to other adjuvant strategies. These results suggest underutilization of neoadjuvant treatment for patients with node-negative Pancoast tumors. Future studies with a more clearly defined cohort are needed to assess the treatment patterns being utilized on patients with node-negative Pancoast tumors. It will be beneficial to see whether neoadjuvant treatment for Pancoast tumors has increased in recent years.

Public health and medical preparedness for mass casualties from the deliberate release of synthetic opioids.

The large amounts of opioids and the emergence of increasingly potent illicitly manufactured synthetic opioids circulating in the unregulated drug supply in North America and Europe are fueling not only the ongoing public health crisis of overdose deaths but also raise the risk of another type of disaster: deliberate opioid release with the intention to cause mass harm. Synthetic opioids are highly potent, rapidly acting, can cause fatal ventilatory depression, are widely available, and have the potential to be disseminated for mass exposure, for example, if effectively formulated, via inhalation or ingestion. As in many other chemical incidents, the health consequences of a deliberate release of synthetic opioid would manifest quickly, within minutes. Such an incident is unlikely, but the consequences could be grave. Awareness of the risk of this type of incident and preparedness to respond are required to save lives and reduce illness. Coordinated planning across the entire local community emergency response system is also critical. The ability to rapidly recognize the opioid toxidrome, education on personal protective actions, and training in medical management of individuals experiencing an opioid overdose are key components of preparedness for an opioid mass casualty incident.

Hospice and physician-assisted death: collaboration, compliance, and complicity.

Although the overwhelming majority of terminally ill patients in Oregon who seek a physician's aid in dying are enrolled in hospice programs, hospices do not take a major role in this practice. An examination of fifty-five Oregon hospices reveals that both legal and moral questions prevent hospices from collaborating fully with physician-assisted death.

Cervical Spine Injury in Burned Trauma Patients: Incidence, Predictors, and Outcomes.

Cervical spine injuries (CIs) carry significant morbidity and mortality; hence, cervical spine immobilization is used liberally in trauma patients, including burns. The incidence, predictors, and outcomes of CI in burn patients are unknown. A retrospective cohort from the National Trauma Data Bank between 2007 and 2012 included all burned patients with and without CI. Predictors of CI were identified by logistic regression. Outcomes with and without CI were compared with Wilcoxon rank sum test. A total of 94,964 patients were identified with burn injuries. The incidence of CI was 0.79% (n = 745). Mechanism of injury, age, and injury severity score (ISS) were significant predictors of CI. Odds of CI were 109.4 (95% CI: 61.2-195.3, P < .0001) for motor vehicle injury, 87.8 (95% CI: 47.0-164.0, P < .0001) for falls, 1.2 (95% CI: 0.6-2.3, P = .66) for fire/flame, and 2.4 (95% CI: 1.0-5.5, P < .0001) for explosion compared with reference of hot object/substance. For every year increase in age, there were 1.02 higher odds of CI (95% CI: 1.01-1.02, P < .0001). For each point increase in ISS, there were 1.05 higher odds of CI (95% CI: 1.04-1.05, P < .0001). Patients with CI had higher mortality (10.3% vs 2.9%, P < .0001), longer total length of stay (12.0 vs 2.0 days, P < .0001), intensive care unit length of stay (4.0 vs 0.0 days, P < .001), and ventilator days (1.0 vs 0.0 days, P < .0001). The incidence of CI in burn patients is low, especially when due to fire, flame, or scalds; however, CI is associated with higher mortality and worse outcomes.

The EGS grading scale for skin and soft-tissue infections is predictive of poor outcomes: a multicenter validation study.

INTRODUCTION: Over the last 5 years, the American Association for the Surgery of Trauma has developed grading scales for emergency general surgery (EGS) diseases. In a previous validation study using diverticulitis, the grading scales were predictive of complications and length of stay. As EGS encompasses diverse diseases, the purpose of this study was to validate the grading scale concept against a different disease process with a higher associated mortality. We hypothesized that the grading scale would be predictive of complications, length of stay, and mortality in skin and soft-tissue infections (STIs). METHODS: This multi-institutional trial encompassed 12 centers. Data collected included demographic variables, disease characteristics, and outcomes such as mortality, overall complications, and hospital and ICU length of stay. The EGS scale for STI was used to grade each infection and two surgeons graded each case to evaluate inter-rater reliability. RESULTS: 1170 patients were included in this study. Inter-rater reliability was moderate (kappa coefficient 0.472-0.642, with 64-76% agreement). Higher grades (IV and V) corresponded to significantly higher Laboratory Risk Indicator for Necrotizing Fasciitis scores when compared with lower EGS grades. Patients with grade IV and V STI had significantly increased odds of all complications, as well as ICU and overall length of stay. These associations remained significant in logistic regression controlling for age, gender, comorbidities, mental status, and hospital-level volume. Grade V disease was significantly associated with mortality as well. CONCLUSION: This validation effort demonstrates that grade IV and V STI are significantly predictive of complications, hospital length of stay, and mortality. Though predictive ability does not improve linearly with STI grade, this is consistent with the clinical disease process in which lower grades represent cellulitis and abscess and higher grades are invasive infections. This second validation study confirms the EGS grading scale as predictive, and easily used, in disparate disease processes. LEVEL OF EVIDENCE: Prognostic/Epidemiologic retrospective multicenter trial, level III.
