Oncologic outcomes after nipple-sparing mastectomy: A single-institution experience. - Journal of surgical oncology
Long-term oncologic outcomes in nipple-sparing mastectomy (NSM) continue to be defined. Rates of locoregional recurrence for skin-sparing mastectomy (SSM) and NSM in the literature range from 0% to 14.3%. We investigated the outcomes of NSM at our institution.Patients undergoing NSM at our institution from 2006 to 2014 were identified and outcomes were analyzed.From 2006 to 2014, 319 patients (555 breasts) underwent NSM. One-hundered and fourty-one patients (237 breasts) had long-term follow-up available. Average patient age and BMI were 47.78 and 24.63. Eighty-four percent of patients underwent mastectomy primarily for a therapeutic indication. Average tumor size was 1.50 cm with the most common histologic type being invasive ductal carcinoma (62.7%) followed by DCIS (23.7%). Average patient follow-up was 30.73 months. There was one (0.8%) incidence of ipsilateral chest-wall recurrence. There were 0.37 complications per patient.We examined our institutional outcomes with NSM and found a locoregional recurrence rate of 0.8% with no nipple-areolar complex recurrence. This rate is lower than published rates for both NSM and SSM. J. Surg. Oncol. 2016;113:8-11. © 2015 Wiley Periodicals, Inc.© 2015 Wiley Periodicals, Inc.
Neural Reanimation Advances and New Technologies. - Facial plastic surgery clinics of North America
Facial paralysis can have a profound effect on the patient from both an aesthetic and functional point of view. Just as there are numerous etiologies of facial paresis, there are as many therapeutic options and variations of these options. The purpose of this article was to review the most current surgical options for neural reanimation of a damaged facial nerve, including recent advances in nerve repair, conduit technology, and nerve transfers, as well as emerging technology in translational research with biomedical engineering and tissue engineering.Copyright © 2016 Elsevier Inc.

A randomized, double-blind, placebo-controlled study of omalizumab combined with oral immunotherapy for the treatment of cow's milk allergy. - The Journal of allergy and clinical immunology
Although studies of oral immunotherapy (OIT) for food allergy have shown promise, treatment is frequently complicated by adverse reactions and, even when successful, has limited long-term efficacy because benefits usually diminish when treatment is discontinued.We sought to examine whether the addition of omalizumab to milk OIT reduces treatment-related reactions, improves outcomes, or both.This was a double-blind, placebo-controlled trial with subjects randomized to omalizumab or placebo. Open-label milk OIT was initiated after 4 months of omalizumab/placebo with escalation to maintenance over 22 to 40 weeks, followed by daily maintenance dosing through month 28. At month 28, omalizumab was discontinued, and subjects passing an oral food challenge (OFC) continued OIT for 8 weeks, after which OIT was discontinued with rechallenge at month 32 to assess sustained unresponsiveness (SU).Fifty-seven subjects (7-32 years) were randomized, with no significant baseline differences in age, milk-specific IgE levels, skin test results, or OFC results. At month 28, 24 (88.9%) omalizumab-treated subjects and 20 (71.4%) placebo-treated subjects passed the 10-g "desensitization" OFC (P = .18). At month 32, SU was demonstrated in 48.1% in the omalizumab group and 35.7% in the placebo group (P = .42). Adverse reactions were markedly reduced during OIT escalation in omalizumab-treated subjects for percentages of doses per subject provoking symptoms (2.1% vs 16.1%, P = .0005), dose-related reactions requiring treatment (0.0% vs 3.8%, P = .0008), and doses required to achieve maintenance (198 vs 225, P = .008).In this first randomized, double-blind, placebo-controlled trial of omalizumab in combination with food OIT, we found significant improvements in measurements of safety but not in outcomes of efficacy (desensitization and SU).Copyright © 2015 American Academy of Allergy, Asthma & Immunology.

Cervicofacial Rhytidectomy After Radiotherapy for Head and Neck Tumors. - JAMA facial plastic surgery
Whether undergoing cervicofacial rhytidectomy after radiotherapy for tumors of the head and neck is associated with increased complication rates and therefore should be avoided remains unknown.To evaluate complication rates in patients who have undergone cervicofacial rhytidectomy after radiotherapy for head and neck tumors and compare these rates with those of patients who have not undergone radiotherapy.Retrospective review of the medical records of 16 patients who underwent cervicofacial rhytidectomy after completing radiotherapy for head and neck tumors and those of 16 age-matched control participants who did not undergo radiotherapy. Patients underwent treatment from July 1, 2006, through February 28, 2014, with final follow-up on February 28, 2014. Complications after surgery were reviewed and data for surgery type, technique, radiation dose and delivery method, and time to surgery after radiotherapy were analyzed. Data were collected from June 1 through December 31, 2013, and analyzed from January 1, 2014, through June 1, 2015.Rate of complications after surgery.The radiotherapy and control group patients were a mean of 62 years old. In the radiotherapy group, 8 of 16 were women; 14 of 16 were women in the control group. Two major complications, 1 hematoma and 1 perioperative stroke, occurred in the 16 patients who composed the study cohort. In the control group, there was 1 case of transient facial nerve weakness and 1 case of cellulitis that was successfully treated with antibiotics. Two patients experienced wound dehiscence, and no incidents of motor or sensory nerve injury occurred. Subcutaneous face-lift (3 of 3 patients [100%] vs 1 of 13 patients [8%] who underwent superficial musculoaponeurotic system and deep-plane face-lifts; P = .02) and the addition of chemotherapy (4 of 9 patients [44%] vs 0 of 7 patients who did not receive chemotherapy; P = .04) were associated with increased complications. Being older and the time from completion of radiotherapy and surgery did not show any correlation to complications.Aesthetic facial surgery after radiotherapy has an increased risk for complication compared with facial surgery without radiotherapy. The incidence of wound dehiscence is elevated in the population undergoing radiotherapy but can be managed conservatively in most cases. Patients who undergo radiotherapy must be counseled on the increased risk for complications before proceeding with cervicofacial rhytidectomy.3.
Ngn1 inhibits astrogliogenesis through induction of miR-9 during neuronal fate specification. - eLife
It has been postulated that a proneural factor, neurogenin 1 (Ngn1), simultaneously activates the neurogenic program and inhibits the alternative astrogliogenic program when specifying the neuronal fate. While Ngn1 substantially suppresses the activation of the astrogliogenic Jak-Stat pathway, the underlying molecular mechanism was unknown. Here, by employing in vivo and in vitro approaches, we report that Ngn1 binds to the promoter of a brain-enriched microRNA, miR-9, and activates its expression during neurogenesis. Subsequently, our in vitro study showed that miR-9 directly targets mRNAs of Lifr-beta, Il6st (gp130), and Jak1 to down-regulate these critical upstream components of the Jak-Stat pathway, achieving inhibition of Stat phosphorylation and consequently, suppression of astrogliogenesis. This study revealed Ngn1 modulated non-coding RNA epigenetic regulation during cell fate specifications.
Subjective well-being, social buffering and hedonic editing in the quotidian. - Cognition & emotion
A previous study on the relationship between subjective well-being (SWB) and hedonic editing-the process of mentally integrating or segregating different events during decision-making-showed that happy individuals preferred the social-buffering strategy more than less happy individuals. The present study examined the relationship between SWB, social-buffering and hedonic outcomes in daily life. In Study 1, we used web-based diaries to measure the frequency with which individuals utilised social and non-social buffers as well as daily levels of happiness. Consistent with the previous finding, happy individuals utilised social buffers more frequently than less happy individuals. Interestingly, the utilisation of social buffers had a positive effect on daily happiness among all participants, regardless of individuals' levels of SWB. In Study 2, we found that although the use of social buffers yielded similar effects across groups on online evaluations of events, happy individuals showed a positive bias in global evaluations of past events. This finding suggests that how one construes and remembers the outcomes of social buffering may shape the different hedonic editing preferences among happy and less happy individuals.
Far-lateral transcondylar approach for microsurgical trapping of an anterior inferior cerebellar artery aneurysm. - Neurosurgical focus
Aneurysms of the posterior circulation remain challenging lesions given their proximity to the brainstem and cranial nerves. Many of these aneurysms may best be approached through a retrosigmoid-suboccipital craniectomy with a far-lateral transcondylar extension. In this narrated video illustration, we present the case of a 37-year-old man with an incidentally discovered right-sided anterior inferior cerebellar artery (AICA) aneurysm. Diagnostic studies included CT angiography and cerebral angiography. A suboccipital craniectomy and far-lateral transcondylar extension were performed for microsurgical trapping and excision of the AICA aneurysm. The techniques of the retrosigmoid craniectomy, C-1 laminectomy, condylectomy and microsurgical trapping of the aneurysm are reviewed. The video can be found here:
A multicenter study of 30 days complications after deceased donor liver transplantation in the model for end-stage liver disease score era. - Liver transplantation : official publication of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society
Knowledge of risk factors for posttransplant complications is likely to improve patient outcomes. Few large studies of all early postoperative complications after deceased donor liver transplantation (DDLT) exist. Therefore, we conducted a retrospective, cohort study of 30-day complications, their risk factors, and the impact on outcomes after DDLT. Three centers contributed data for 450 DDLTs performed from January 2005 through December 2009. Data included donor, recipient, transplant, and outcome variables. All 30-day postoperative complications were graded by the Clavien-Dindo system. Complications per patient and severe (≥ grade III) complications were primary outcomes. Death within 30 days, complication occurrence, length of stay (LOS), and graft and patient survival were secondary outcomes. Multivariate associations of risk factors with complications and complications with LOS, graft survival, and patient survival were examined. Mean number of complications/patient was 3.3 ± 3.9. At least 1 complication occurred in 79.3%, and severe complications occurred in 62.8% of recipients. Mean LOS was 16.2 ± 22.9 days. Graft and patient survival rates were 84% and 86%, respectively, at 1 year and 74% and 76%, respectively, at 3 years. Hospitalization, critical care, ventilatory support, and renal replacement therapy before transplant and transfusions during transplant were the significant predictors of complications (not the Model for End-Stage Liver Disease score). Both number and severity of complications had a significant impact on LOS and graft and patient survival. Structured reporting of risk-adjusted complications rates after DDLT is likely to improve patient care and transplant center benchmarking. Despite the accomplished reductions in transfusions during DDLT, opportunities exist for further reductions. With increasing transplantation of sicker patients, reduction in complications would require multidisciplinary efforts and institutional commitment. Pretransplant risk characteristics for complications must factor in during payer contracting.© 2015 American Association for the Study of Liver Diseases.
Technical note: Orbitozygomatic craniotomy using an ultrasonic osteotome for precise osteotomies. - Clinical neurology and neurosurgery
The orbitozygomatic craniotomy is a fundamental procedure in neurosurgery, allowing access to orbital and skull base pathology.Determine the feasibility of using an ultrasonic osteotome to safely perform orbitozygomatic osteotomies in patients with intracranial pathology.The medical records of patients undergoing orbitozygomatic craniotomy using an ultrasonic osteotome (Aesculap BoneScalpel™) for tumor resection at Johns Hopkins Hospital between November 2009 and March 2013 were retrospectively reviewed.Six patients underwent orbitozygomatic craniotomy for tumor resection using an ultrasonic osteotome at the Johns Hopkins Hospital during the study period. All patients were female and the average age was 53.2 years. Patients were followed for an average of 375 days. There were two cases of transient diplopia. There were no cases of periorbital violation, orbital injury, enophthalmos, or orbital hematoma. Post-operative imaging showed the cuts were well opposed and no cosmetic issues were encountered.Use of an ultrasonic osteotome allows for precise cuts under direct visualization with minimal risk to critical adjacent structures in our cohort of patients undergoing a two-piece orbitozygomatic craniotomy. This appears to be a safe instrument for osteotomy creation in skull base approaches.Copyright © 2015 Elsevier B.V. All rights reserved.
Soft-tissue reconstruction after total en bloc sacrectomy. - Journal of neurosurgery. Spine
OBJECT Total en bloc sacrectomy is a dramatic procedure that results in extensive sacral defects. The authors present a series of patients who underwent flap reconstruction after total sacrectomy, report clinical outcomes, and provide a treatment algorithm to guide surgical care of this unique patient population. METHODS After institutional review board approval, data were collected for all patients who underwent total sacrectomy between 2002 and 2012 at The Johns Hopkins Hospital. Variables included demographic data, medical history, tumor characteristics, surgical details, postoperative complications, and clinical outcomes. All subtotal sacrectomies were excluded. RESULTS Between 2002 and 2012, 9 patients underwent total sacrectomy with flap reconstruction. Diagnoses included chordoma (n = 5), osteoblastoma (n = 1), sarcoma (n = 2), and metastatic colon cancer (n = 1). Six patients received gluteus maximus (GM) flaps with a prosthetic rectal sling following a single-stage, posterior sacrectomy. Four required additional paraspinous muscle (PSM) or pedicled latissimus dorsi (LD) fasciocutaneous flaps. Three patients underwent multistage sacrectomy with an anterior-posterior approach, 2 of whom received pedicled vertical rectus abdominis myocutaneous (VRAM) flaps, and 1 of whom received local GM, LD, and PSM flaps. Flap complications included dehiscence (n = 4) and infection (n = 1). During the 1st year of follow-up, 2 of 9 patients (22%) were able to ambulate with an assistive device by the 1st postoperative month, and 6 of 9 (67%) were ambulatory with a walker by the 3rd postoperative month. By postoperative Month 12, 5 of 9 patients (56%)-or 5 of 5 patients not lost to follow-up (100%)-were able to able to ambulate independently. CONCLUSIONS The authors' experience suggests that the GM and pedicled VRAM flaps are reliable options for softtissue reconstruction of total sacrectomy defects. For posterior-only operations, GM flaps with or without a prosthetic rectal sling are generally used. For multistage operations including a laparotomy, the authors consider the pedicled VRAM flap to be the gold standard for simultaneous reconstruction of the pelvic diaphragm and obliteration of dead space.
