A retrospective review of outcomes after hyperbaric oxygen therapy for the treatment of calciphylaxis.

BACKGROUND: Calciphylaxis is a thrombotic vasculopathy characterized by painful necrotic ulcerations. There are no Food and Drug Administration approved therapies despite high mortality. OBJECTIVE: To compare mortality and wound healing outcomes in patients treated with hyperbaric oxygen therapy (HBOT) in addition to intravenous sodium thiosulfate (IV STS) versus patients who received IV STS only. Findings were stratified by dialysis status and modality. METHODS: 93 patients were included, with 57 patients in the control group (IV STS) and 36 patients in the treatment group (HBOT + IV STS). Mortality data were analyzed with traditional survival analyses and Cox proportional hazard models. Longitudinal wound outcomes were analyzed with mixed effects modeling. RESULTS: Univariate survival analyses showed that full HBOT treatment was associated with significantly (P = .016) longer survival time. Increasing number of HBOT sessions was associated with improved mortality outcomes, with 1, 5, 10 and 20 sessions yielding decreasing hazard ratios. There was also a significant (P = .042) positive association between increasing number of HBOT sessions and increased wound score. LIMITATIONS: Data collection was retrospective. CONCLUSION: HBOT may have a role in the treatment of calciphylaxis with benefits demonstrated in both mortality and wound healing. Larger prospective studies are needed to identify which patients would most benefit from this intervention.

A case of drug rash with eosinophilia and systemic symptoms (DRESS) syndrome complicating airway management.

PURPOSE: Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a severe multi-system reaction defined by fever, rash, eosinophilia, and internal organ involvement. The condition typically occurs one to eight weeks following exposure to inciting medications. In severe cases, it can develop into multi-organ system failure and death. We present a case of DRESS syndrome with mucosal edema that led to extreme difficulties with airway management. CLINICAL FEATURES: A 65-yr-old male treated for an esophageal perforation with broad-spectrum antibiotics developed fever, eosinophilia, and extensive rash consistent with DRESS syndrome. This condition resulted in a rapid progression to multi-organ system dysfunction, severe hemodynamic instability, and the need for high-dose vasopressors and tracheal intubation. Extensive mucous membrane involvement led to significant complications with airway management and a nearly impossible tracheal intubation, features in the disease not previously described. With the airway secure, initiation of steroids resulted in regression of the disease within 24 hr, resolution of airway edema, and uneventful tracheal extubation a few days later. CONCLUSION: We emphasize the need for early identification of DRESS syndrome as well as the possible airway implications associated with this increasingly recognized clinical entity.

Assessment of Preoperative Functional Status Prior to Major Head and Neck Surgery: A Pilot Study.

OBJECTIVE: To demonstrate feasibility of a recently developed preoperative assessment tool, the Vulnerable Elders Surgical Pathways and Outcomes Analysis (VESPA), to characterize the baseline functional status of patients undergoing major head and neck surgery and to examine the relationship between preoperative functional status and postoperative outcomes. STUDY DESIGN: Case series with planned data collection. SETTING: Two tertiary care academic hospitals. METHODS: The VESPA was administered prospectively in the preoperative setting. Data on patient demographics, ablative and reconstructive procedures, and outcomes including total length of stay, discharge disposition, delay in discharge, or complex discharge planning (delay or change in disposition) were collected via retrospective chart review. VESPA scores were calculated and risk categories were used to estimate risk of adverse postoperative outcomes using multivariate logistic regression for categorical outcomes and linear regression for continuous variables. RESULTS: Fifty-eight patients met study inclusion criteria. The mean (SD) age was 66.4 (11.9) years, and 58.4% of patients were male. Nearly one-fourth described preoperative difficulty in either a basic or instrumental activity of daily living, and 17% were classified as low functional status (ie, high risk) according to the VESPA. Low functional status did not independently predict length of stay but was associated with delayed discharge (odds ratio [OR], 5.0; 95% CI, 1.2-21.3; P = .030) and complex discharge planning (OR, 5.7; 95% CI, 1.34-24.2; P = .018). CONCLUSION: The VESPA can identify major head and neck surgical patients with low preoperative functional status who may be at risk for delayed or complex discharge planning. These patients may benefit from enhanced preoperative counseling and more comprehensive discharge preparation.

Regression of Some High-risk Features of Age-related Macular Degeneration (AMD) in Patients Receiving Intensive Statin Treatment.

IMPORTANCE: Age-related macular degeneration (AMD) remains the leading cause of blindness in developed countries, and affects more than 150 million worldwide. Despite effective anti-angiogenic therapies for the less prevalent neovascular form of AMD, treatments are lacking for the more prevalent dry form. Similarities in risk factors and pathogenesis between AMD and atherosclerosis have led investigators to study the effects of statins on AMD incidence and progression with mixed results. A limitation of these studies has been the heterogeneity of AMD disease and the lack of standardization in statin dosage. OBJECTIVE: We were interested in studying the effects of high-dose statins, similar to those showing regression of atherosclerotic plaques, in AMD. DESIGN: Pilot multicenter open-label prospective clinical study of 26 patients with diagnosis of AMD and the presence of many large, soft drusenoid deposits. Patients received 80 mg of atorvastatin daily and were monitored at baseline and every 3 months with complete ophthalmologic exam, best corrected visual acuity (VA), fundus photographs, optical coherence tomography (OCT), and blood work (AST, ALT, CPK, total cholesterol, TSH, creatinine, as well as a pregnancy test for premenopausal women). RESULTS: Twenty-three subjects completed a minimum follow-up of 12 months. High-dose atorvastatin resulted in regression of drusen deposits associated with vision gain (+ 3.3 letters, p = 0.06) in 10 patients. No subjects progressed to advanced neovascular AMD. CONCLUSIONS: High-dose statins may result in resolution of drusenoid pigment epithelial detachments (PEDs) and improvement in VA, without atrophy or neovascularization in a high-risk subgroup of AMD patients. Confirmation from larger studies is warranted.

Successful management of a morbidly obese patient for electroconvulsive therapy with elective tracheostomy.

Electroconvulsive therapy (ECT) is a treatment for affective catatonia and requires multiple general anesthetics. Morbid obesity is an increasingly prevalent condition that may complicate the standard anesthetic management of a patient undergoing ECT. We report the successful airway management of a morbidly obese ECT patient via elective tracheostomy.
