Our objective was to perform a systematic review of the literature on contemporary indications and outcomes for frontal sinus trephination and present an illustrative case of an endoscopically assisted repair of a subcutaneous frontal sinus fistula by trephination technique. PubMed and Ovid databases were used as data sources. A systematic review of the English literature was completed to review reports of frontal trephination from 1980 to 2014. Articles meeting inclusion criteria for inflammatory and noninflammatory indications were reviewed. Articles were systematically reviewed and graded by evidence‐based medicine level. An illustrative case from our institution is then presented. The systematic review identified 2,621 published studies. Thirty‐eight studies were identified for inclusion. The indications, techniques, outcomes, safety, and complications were reviewed for noninflammatory and inflammatory conditions. There were 32 retrospective case series, reports, or cohort studies (level 4), four systematic reviews (level 3), one prospective analysis (level 3), and one meta‐analysis (level 2). Due to the heterogeneity of study cases and inclusion criteria, a meta‐analysis was not feasible. We also present a novel closure of an anterior skull base defect resulting in a subcutaneous fistula with use of a frontal trephination approach. The frontal sinus trephination should not be regarded as a procedure of the past, as it useful in the armamentarium of the modern sinus and skull base surgeon. This approach provides access for instrumentation for hard‐to‐reach frontal sinus disease either purely through a trephination approach or as a supplementation to the transnasal endoscopic approach. Evidence supporting frontal sinus trephination is of levels 2, 3, and 4.Level of EvidenceNALaryngoscope, 125:2046–2053, 2015

Three-dimensional polymer scaffolds with interconnected porous structures were fabricated by thermally induced phase separation of novel biodegradable poly(propylene fumarate)- co -poly( l -lactic acid).

The aerial parts of Amphoricarpos neumayeri ssp. murbeckii afforded eleven guaianolides with the same relative (1αH,4β H,5αH,7αH) configuration of the basic skeleton. All of them contained a CH2OX (X = H, acetyl or isovaleroyl) group in 4α-position, typical for amphoricarpolides. Four compounds (1 - 4) were isolated before from the same species, originating from different localities. Guaianolides 5 - 11 are new compounds. Compounds 7 and 8 were epoxidized at the 10α(14)-position. Instead of the Δ11(13)-double bond, observed in all previously isolated guaianolides from the same species, the four lactones contained 11α,13-diol (8 - 10) or 11α-OH,13-chloro (11) moieties respectively.

Acupuncture is used to treat a variety of symptoms and conditions associated with cancer and cancer treatments. The present study was performed to evaluate the feasibility of providing acupuncture in the hospital setting for breast cancer patients and to evaluate the short-term effect of acupuncture on stress, anxiety, and pain. This was an open label study conducted at Mayo Clinic Hospital, Methodist and Saint Marys Campus, Rochester, Minnesota. A total of 20 adult breast cancer patients undergoing mastectomy and/or breast reconstruction were recruited and offered daily acupuncture intervention beginning postoperative day 1 and continuing for the duration of the hospital stay. Outcome measures included the Symptom Visual Analog Scale (VAS) and Satisfaction Question and Was-it-Worth-it (WIWI) Questionnaire. It was found that acupuncture is a feasible option for postoperative breast cancer patients. In addition, it can significantly decrease the levels of anxiety (p = 0.0065), tension/muscular discomfort (p < 0.001) and pain (p = 0.023). The association between acupuncture and relaxation was found to be statistically borderline (p = 0.053). This feasibility study showed that acupuncture can be integrated into a busy postsurgical clinical practice. These results also suggest that acupuncture may be an important intervention in the postoperative setting for breast cancer patients.

Most studies in polycythemia vera (PV) include patients with both remote and most recent diagnostic periods and are therefore vulnerable to inaccurate interpretation of time‐dependent data. We addressed the particular issue by analyzing presenting characteristics and outcome data among 1,545 patients with WHO‐defined PV stratified by a diagnosis period of before or after 2005, which coincides with the first description of JAK2V617F as the molecular marker of PV. Patients diagnosed after 2005 displayed lower hemoglobin values (P < 0.0001) and older age (P = 0.007) at diagnosis; we suggest ease of diagnosis offered by a molecular marker enabled earlier diagnosis and broader application across older age groups that is further enhanced by recent trends in increased attention and health monitoring for the elderly. Post‐2005 diagnosed patients were also more or less likely to receive aspirin and cytoreductive therapy, respectively, and, despite their older age distribution, displayed significantly lower risk of thrombosis in high risk disease. Regardless of the contributing factors to the latter phenomenon, our observations underscore the need to reassess current demographics and frequencies of thrombosis in clinical trial designs including thrombosis prevention in PV.

AbstractBackgroundAllogeneic hematopoietic stem cell transplant (allo‐HSCT) recipients have multiple risk factors for coccidioidomycosis, and previous reports of coccidioidomycosis in this patient population describe severe infections with poor outcomes.MethodsWe performed a retrospective chart review of allo‐HSCT recipients with active coccidioidomycosis to characterize the utility of diagnostic tests for coccidioidomycosis and to determine treatment outcomes.ResultsEleven of 426 (2.6%) allo‐HSCT recipients experienced active coccidioidomycosis after transplantation. Of these 11 patients, 1 (9%) had extrapulmonary infection, 9 (82%) patients were hospitalized, and 5 (45%) died. Culture or histology was positive in 33% (3/9) of the patients tested. Most (64% [7/11]) had at least 1 positive serologic test result, and the enzyme immunoassay immunoglobulin G test was positive most often (overall 55% [6/11]). Chest radiographs and chest computed tomography scans showed miliary or multifocal nodular infiltrates or consolidations, consistent with coccidioidomycosis, in 80% (8/10) and 100% (9/9), respectively, of patients tested throughout the course of active illness. Rapid polymerase chain reaction testing was positive in 71% (5/7) of the patients tested. Peripheral eosinophilia was present in 18% (2/11) of patients.ConclusionCoccidioidomycosis is associated with high morbidity and mortality in allo‐HSCT recipients in an area endemic for Coccidioides. Diagnosis of this infection can be difficult and often requires multiple and frequently invasive tests. Antifungal prophylaxis should be considered for patients at highest risk.
