AbstractBackgroundHailey–Hailey disease (HHD) is an autosomal dominant genodermatosis that leads to skin breakdown and blister formation, usually in intertriginous areas. Laser ablation is a known surgical treatment for HHD.ObjectivesWe report outcomes in a series of patients with HHD treated with carbon dioxide (CO2) laser ablation.MethodsA retrospective chart review of data for 13 patients who underwent CO2 laser ablation for HHD was conducted. Questionnaires assessing effectiveness, pain, healing time, recurrence, new disease, complications, additional ablation, improvement in quality of life (QoL), and overall satisfaction were completed by all patients.ResultsAll patients had been recalcitrant to previous treatments prior to CO2 laser ablation. Anatomic sites treated and anesthesia techniques for the procedure varied. The mean ± standard deviation (SD) score for the effectiveness of CO2 laser ablation for HHD was 9.3 ± 0.9 (maximum: 10). All patients reported improved QoL. No patient had recurring disease within the treatment field. Five patients underwent additional CO2 laser treatments at new sites. One patient reported postoperative infection. No other complications were identified. The mean ± SD score for overall satisfaction with CO2 laser ablation was 8.9 ± 1.1.ConclusionsTreatment with CO2 laser ablation is very effective and can lead to prolonged or permanent remission in most HHD patients. Patients are highly satisfied with the results and report a substantial improvement in QoL.

Objective Cardiac angiosarcoma is the most common primary malignant cardiac tumor. The dismal prognosis and nonspecific symptomatology underscore the need for an accurate and cost‐effective approach to the identification and characterization of this rare tumor. Methods Mayo Clinic tissue registry archives were queried for all histologically confirmed cases of cardiac angiosarcoma (1976–2013) with available imaging data. Echocardiograms were retrospectively reviewed. Results Thirty‐three cases of cardiac angiosarcoma were identified; of these, 17 had echocardiograms available (mean age, 46 years; six men). Transthoracic echocardiography ( TTE ) as the initial diagnostic test had 75% sensitivity for visualizing primary cardiac angiosarcoma (9/12 patients). Tumor extension into the pericardium was common and pericardial effusion was present in 15 patients (88%); however, pericardial fluid cytology was negative for malignancy in all tested patients (n = 15). Left ventricular ejection fraction ( LVEF ) was preserved in 16 patients (94%) (average LVEF , 62%). Right ventricular function was mildly reduced in two patients (12%) at initial presentation. Tricuspid valve obstruction was present in three patients (18%; mean diastolic gradient, 6.3 mmHg [range, 3–11 mmHg]). Conclusion The sensitivity of TTE as the first diagnostic imaging modality compared favorably with computed tomography. Pericardial effusion was common, but pericardial fluid cytology was negative in all patients who underwent pericardiocentesis. The absence of a stalk was a universal finding that may help distinguish angiosarcoma from benign, primarily pedunculated tumors such as myxoma and papillary fibroelastoma.

SummaryBackgroundCigarette smoking and secondhand smoke exposure (SHS) increase the risk of perioperative complications. Traditionally, anesthesiologists have limited involvement in tobacco control.ObjectiveTo develop and disseminate an educational curriculum that educates pediatric anesthesia fellows in tobacco control.MethodsAfter IRB approval, an online survey was disseminated to pediatric anesthesiology fellowship directors.ResultsThirty‐one surveys were completed. Most report that they ask pediatric patients about tobacco use. A majority advise their patients who smoke about the health effects of smoking, but only 40% advise children to quit, and the majority never provide educational materials to assist in smoking cessation. Half reported that they sometimes or always ask about SHS. Approximately one‐third never advise about the ill effects of SHS, nearly half never advise parents to stop smoking, and the majority never provide educational material about quitting to parents. Two‐thirds felt that it is their responsibility to advise pediatric patients not to smoke, but less than half felt the same sense of responsibility about advising parents not to smoke. Approximately two‐thirds believe that fellowship programs should provide education about the effects of smoking in the perioperative period and the effects of SHS exposure, but few programs do. Almost all would implement a free teaching module about SHS exposure and tobacco control as part of fellowship education.ConclusionsMany pediatric anesthesiology fellowship directors agree that exposure to cigarette smoke adversely impacts patients in the perioperative period, but few participate in tobacco control, and issues germane to tobacco control are not consistently addressed.

SummaryInvasive mucormycosis is a rare fungal infection in immunocompromised hosts, but it carries a high mortality rate. Primary gastrointestinal disease is the least frequent form of presentation. Early diagnosis and treatment are critical in the management; however, symptoms are typically non‐specific in gastrointestinal disease, leading to delayed therapy. To describe the clinical presentation, diagnosis, treatment and outcomes of gastrointestinal mucormycosis in immunocompromised hosts, we reviewed all cases of primary gastrointestinal mucormycosis in immunocompromised hosts reported in English literature as well as in our Institution from January 1st 1991 to December 31st 2013 for a total of 31 patients. About 52% of patients underwent solid organ transplant (SOT), while the rest had an underlying haematologic malignancy. Abdominal pain was the most common presenting symptom, followed by gastrointestinal bleeding and fever. Gastric disease was more common in SOT, whereas those with haematologic malignancy presented with intestinal disease (P = 0.002). Although gastrointestinal mucormycosis remains an uncommon condition in immunocompromised hosts, it carries significant morbidity and mortality, particularly in cases with intestinal involvement. A high index of suspicion is of utmost importance to institute early and appropriate therapy and improve outcomes.

Tyrosine kinase inhibitors (TKI) are the initial treatment for majority of newly diagnosed patients with chronic myelogenous leukemia (CML) in chronic phase (CP) and are associated with marked improvement in hematological, cytogenetic, molecular response and survival rates compared with other therapies. In this review, we summarize the evidence of TKI efficacy for patients with newly diagnosed CP‐CML. Six trials at low risk of bias evaluating TKIs as an initial treatment in adults with newly diagnosed CP‐CML and enrolling 2,456 patients were included. Follow‐up times ranged from a median of 3 months to 5 years. Direct comparison showed statistically higher rates of major molecular response (MMR ≤ 0.1%IS) achievement with second‐generation TKIs at 12 months which was sustained throughout treatment period. Bayesian mixed‐treatment comparison (MTC) analysis demonstrated superiority of both nilotinib and dasatinib over imatinib in terms of efficacy. Nilotinib was associated with higher deeper molecular responses (MR4.5 ≤ 0.0032%IS) at 60 months than dasatinib but no difference in MMR. The differences between nilotinib and dasatinib are likely clinically trivial. Among TKIs, nilotinib was found to have the best survival profile. Both nilotinib and dasatinib are associated with significantly better MMR compared to imatinib that is sustained over 60 months. This analysis shows that new‐generation TKIs are not only showing faster response but also maintaining a more potent one through longer follow‐up period. It is important to note out that MTC is not a substitute for well‐conducted RCTs investigating direct comparisons.
