AbstractSpring harvest rates of male wild turkeys (Meleagris gallapavo) influence the number and proportion of adult males in the population and turkey population models have treated harvest as additive to other sources of mortality. Therefore, hunting regulations and their effect on spring harvest rates have direct implications for hunter satisfaction. We used tag recovery models to estimate survival rates, investigate spatial, temporal, and demographic variability in harvest rates, and assess how harvest rates may be related to management strategies and landscape characteristics. We banded 3,266 male wild turkeys throughout New York, Ohio, and Pennsylvania during 2006–2009. We found little evidence that harvest rates varied by year or management zone. The proportion of the landscape that was forested within 6.5 km of the capture location was negatively related to harvest rates; however, even though the proportion forested ranged from 0.008 to 0.96 across our study area, this corresponded to differences in harvest rates of only 2–5%. Annual survival was approximately twice as high for juveniles $({\hat {S}} = 0.64- 0.87)$ as adults $({\hat {S}} = 0.30- 0.41)$. In turn, spring harvest rates for adult turkeys were greater for adults $({\hat {H}} = 0.35- 0.39)$ than juveniles $({\hat {H}} = 0.17- 0.27)$. We estimated the population of male turkeys in New York and Pennsylvania ranged from 104,000 to 132,000 in all years and ranged from 63,000 to 75,000 in Ohio. Because of greater harvest rates for adult males, the proportion of adult males in the population was less than in the harvest and ranged from 0.40 to 0.81 among all states and years. The high harvest rates observed for adults may be offset by greater recruitment of juveniles into the adult age class the following year such that these states can sustain high harvest rates yet still maintain a relative high proportion of adult males in the harvest and population. © 2011 The Wildlife Society.
Additional considerations for gray wolf management after their removal from Endangered Species Act protections
Authors: Way Jonathan G. , Bruskotter Jeremy T. 
Published: November 2011

AbstractMech (2010) provided a review of options involving regulated, public hunting of gray wolves (Canis lupus) when states regain control of wolf management. We agree with his general conclusion that the use of lethal management should focus more in areas of conflict and less in wilderness areas, especially near protected places like national parks. Here, we expand on Mech's work and provide additional considerations that could be incorporated into state management plans to make them more acceptable to an increasingly diverse group of interested stakeholders, including: 1) the use of human dimensions research to understand the conditions under which stakeholders find lethal management acceptable, and to evaluate the acceptability of agency efforts to increase tolerance for wolves; 2) employing preventative measures to protect livestock and pets, especially in cases where wolf packs are highly visible to the public; and 3) selective use of sport hunting in areas where wolf impacts are deemed unacceptable. © 2011 The Wildlife Society.
Otologic complications of cotton swab use: One institution's experience
Authors: Smith Matthew , Darrat Ilaaf , Seidman Michael 
Published: November 2011

AbstractObjectives/Hypothesis:To evaluate the indications for observation versus surgery in the management of cotton swab‐induced tympanic membrane perforations (TMP).Study Design:Institutional review board‐approved retrospective cohort study of 1,540 patients with a diagnosis of TMP from 2001 to 2010. Patients with a cotton swab injury were subdivided into two groups: observation and surgery.Methods:Data collection included demographics, symptoms, surgery type, and pre‐ and postintervention audiometry. Successful outcomes were defined as healed TMP; resolution/improvement of vertigo, tinnitus, or facial nerve paralysis; and/or closure of the air‐bone gap (ABG).Results:Fifty‐four of 1,540 patients presented with a cotton swab‐induced TMP. Four of the 54 patients (7.4%) underwent delayed surgical repair with 100% success. Preoperatively, one patient had a facial nerve paralysis and two had vertigo with confirmed perilymphatic fistulae (PLF). Postoperatively, the facial nerve paralysis resolved, and one patient had mild vertigo. Fifty of 54 patients opted to forego surgery with 35 patients available for follow‐up. Thirty‐four (97%) of the 35 patients had spontaneous healing. The average time to perforation closure was 1.75 months. Twelve of 35 patients had no ABG after healing.Conclusions:Observation is an appropriate consideration for patients who have a TMP due to a cotton swab injury. Surgical intervention should be offered early when a PLF is suspected, or if facial paralysis, severe vertigo, and/or profound sensorineural hearing loss are present. As otolaryngologists, we should be reluctant to offer surgical intervention of an acute injury without significant symptoms as most patients will heal spontaneously within 2 months.

Published: November 2011

AbstractIntravascular papillary endothelial hyperplasia (IPEH), also known as Masson's tumor, is a rare vascular lesion characterized by intravascular proliferation of endothelial‐lined papillae and a propensity for manifestation in the head and neck. Signs and symptoms associated with IPEH generally occur due to compressive effects of the lesion on adjacent structures. A rare instance of IPEH occurring in the internal auditory canal is presented herein. Clinical presentation, radiographic and pathologic findings, and management strategies are discussed.
An integrated simulator for endolaryngeal surgery
Authors: Nixon Iain J. , Palmer Frank L. , Ganly Ian , Patel Snehal G. 
Published: November 2011

AbstractThe acquisition and maintenance of skills in transoral microlaryngeal surgery requires extended practice. Effective mentoring of such single‐operator procedures is not possible, making it important for trainee surgeons to acquire basic skills outside of the operating room before participating in procedures on patients. Currently available training simulators use either synthetic materials or human tissue, both of which have limitations. We have designed a hybrid simulator that incorporates a porcine larynx in to an airway training manikin, providing both accurate airway anatomy and natural tissue handling characteristics. This model allows training in the skills required for suspension laryngoscopy and the resection of laryngeal lesions. Further applications could include development of surgical techniques and instruments, and use in accreditation of training and revalidation of trained surgeons.
Estimation of skin removal in aging asian blepharoplasty
Authors: Hsu Amy K , Jen Albert 
Published: November 2011

AbstractObjectives/Hypothesis:To describe a novel method for estimating the amount of skin to resect in upper blepharoplasty in the aging Asian eyelid and to report our experience with this technique.Study Design:Retrospective review of patients in a single private practice.Methods:Resection of skin in upper blepharoplasty in an Asian eyelid can often be less forgiving than in other ethnicities due to the unique anatomy of the supratarsal fold. Excising a maximal amount of excess skin will result in an unfavorable appearance of the upper eyelid in an Asian patient. We applied a technique of pinching the skin while the patient is awake until the patient is satisfied with the appearance. The skin is then measured and the precise amount resected during blepharoplasty. The supratarsal crease is always recreated even in patients who have a preexisting crease. We conducted a retrospective review of 99 consecutive patients who underwent upper blepharoplasty using this technique. All patients were Asian and aged 40 years or older.Results:The study group included 99 patients with a mean age of 55.7 years (range, 42–78 years). The mean follow‐up time was 24 months (range, 12–30 months). The amount of desired skin overhang superior to the supratarsal crease varied considerably among patients. Complications included asymmetry in nine patients (9.1%), scarring in three patients (3.0%), and unfavorable cosmetic result in two patients (2.0%). No patients experienced infection, bleeding, or visual changes.Conclusions:In upper blepharoplasty in the aging Asian eyelid, it is necessary to resect less skin than in the Caucasian patient to achieve the desired appearance of the upper eyelid complex. Using a patient‐assisted approach to estimate the amount of skin to remove, a favorable cosmetic result with a low incidence of complications was achieved in a consecutive series of patients.

Sentinel node biopsy in head and neck desmoplastic melanoma: An analysis of 244 cases
Authors: Smith Valerie A. , Lentsch Eric J. 
Published: November 2011

AbstractObjectives/Hypothesis:Desmoplastic melanoma's low rate of sentinel lymph node (SLN) positivity and predilection for the head and neck region have led some to question the role of sentinel lymph node biopsy (SLNB) in patients with this rare histologic variant. Given desmoplastic melanoma's sarcoma‐like histology and aberrant clinical behavior, we hypothesized that SLN status may not be indicative of outcomes in desmoplastic melanoma of the head neck. The objective of this study was to compare melanoma‐specific survival among patients with head and neck desmoplastic melanoma based on SLN status.Study Design:Retrospective analysis of patient data and outcomes using the Surveillance Epidemiology and End Results (SEER) databaseMethods:The SEER database was queried for patients who were diagnosed with desmoplastic melanoma and underwent SLNB. Clinicopathologic data and 5‐year disease‐specific survival (DSS) were compared among patients with positive and negative SLNs.Results:We identified 244 patients with desmoplastic melanoma of the head and neck who underwent SLNB. Of these, only nine had positive SLNs (3.69%). Among the SLN‐positive patients, five (55.6%) had scalp/neck tumors, three (33.3%) had ulcerated tumors, and tumor thickness ranged from 1.7 to 8.5 mm (mean, 4.8 mm). On univariable and multivariable analysis, SLN positivity did not significantly affect DSS in head and neck desmoplastic melanoma (P = .19 and P = .48, respectively).Conclusions:Our findings provide further evidence against routine SLNB in head and neck desmoplastic melanoma by demonstrating a lack of prognostic significance related to the procedure, and by confirming a significantly low rate of SLN positivity as well.

Published: November 2011

AbstractObjectives/Hypothesis:A new concept of IgG4‐related sclerosing sialadenitis characterized by high serum IgG4 levels and tissue infiltration of IgG4‐expressing plasmacytes has recently been proposed. To determine appropriate serum levels of IgG4 for monitoring disease activity, a total of 36 serum samples and eight tissue samples from patients with IgG4‐related sclerosing sialadenitis were studied.Study Design:A retrospective clinical study at Yamagata University School of Medicine.Methods:The patient group consisted of six males and four females with an average age of 60 years (range, 47–74 years). Serum levels of IgG4 and the density of IgG4‐positive plasmacytes in affected tissues were studied.Results:All patients had elevated serum IgG4 levels (>135 mg/dL), and IgG4‐positive plasmacytes (IgG4+ plasma cells/IgG+ plasma cells >50%) were observed in the involved salivary glands. Six patients with IgG4‐related sclerosing sialadenitis with high IgG4/IgG ratios and prominent infiltration of IgG4‐positive plasmacytes in the involved salivary glands had systemic complications, including pancreatitis, retroperitoneal fibrosis, and/or inflammatory pseudotumor of the lung after swelling of the salivary glands. All six of these patients were successfully treated with systemic corticosteroids.Conclusions:In the six patients with systemic complications, treatment with systemic corticosteroids reduced the salivary gland enlargement and lowered serum IgG4 concentrations. These results suggest that IgG4 plays an important role in the pathogenesis of IgG4‐related sclerosing sialadenitis, and that IgG4 levels and IgG4/IgG ratios may be used as additional indicators of disease activity and as biomarkers for potential life‐threatening complications.
Proposed classification system for reporting 532‐nm pulsed potassium titanyl phosphate laser treatment effects on vocal fold lesions

Published: November 2011

Objectives/HypothesisCurrently, no standard exists for reporting treatment results for the potassium titanyl phosphate (KTP) laser. The goal of this study was to establish a validated classification schema for reporting immediate tissue effects after laser treatment.Study DesignEvaluation of KTP laser video sequences by academic laryngologists with use of the rating system.MethodsA five‐point classification system was developed; this included noncontact angiolysis, epithelial blanching, epithelial disruption, contact epithelial ablation, and contact epithelial ablation with tissue removal. Video recordings were made prospectively for each treatment effect. Ten treatment recordings, with two repeated recordings, were presented to seven academic laryngologists, who were asked to categorize each based on the given classification scheme.ResultsOverall accuracy for the combined reviewers in rating the treatments was 82%. Six of seven reviewers showed perfect intrarater reliability. Accuracy in rating clips did not correlate with the previous number of 532‐nm KTP or 585‐nm pulsed dye laser procedures performed but showed a trend toward correlating with total years in practice. This study reveals that standardized reporting of effects of the KTP laser is feasible.ConclusionsWe believe that results of KTP treatment should be reported using a validated classification system of immediate laser effect, along with specific laser settings. This classification system allows for future systematic evaluation of long‐term treatment results prospectively from single laser treatments.Level of Evidence4. Laryngoscope, 124:1170–1175, 2014

Published: November 2011

AbstractObjectives/Hypothesis:The management of stenoses of Wharton's duct has so far been little investigated or systematized. The development of minimally invasive treatment methods, including sialendoscopy, has made preservation of gland function possible.Study Design:Retrospective study in a tertiary referral center.Methods:A total of 153 stenoses of the submandibular duct were diagnosed and treated in 138 patients. Ultrasound and sialendoscopy were the first‐choice diagnostic measures. A total of 62.7% of the stenoses were located in the distal, 11.1% in the middle segment, and 18.3% in the proximal to posthilar duct. Diffuse stenoses were observed in 7.8% of the cases. Sialendoscopy‐assisted intraductal cortisone administration, interventional sialendoscopy, and transoral ductal surgery were the treatment options. The mean period between treatment and data collection was 52.5 months.Results:Fibrotic stenoses were diagnosed in 88.3% and bilateral involvement in 8.6% of the cases. Distal stenoses were treated predominantly by ductal incision (79.2%). Stenoses of the midsubmandibular duct were treated conservatively in 29.4% or with sialendoscopy or ductal incision in 35.3% of cases each. Proximal up to posthilar stenoses could be dilated by interventional sialendoscopy in 82.2%. In 25% of all diffuse stenoses, glandular resection was carried out, representing 2.6% of all stenoses. Glandular function was preserved in 97.8% of cases.Conclusions:Stenoses of the submandibular duct can be treated using minimally invasive procedures and with preservation of glandular function with a high success rate. Ductal incision procedures are the most important measure, but sialendoscopy becomes more important the more centrally the stenosis is located.
Hollow Polyaniline and Indomethacin Composite Microspheres for Controlled Indomethacin Release
Authors: Zhang Lijuan , Zhang Zhiming , Kilmartin Paul A. , Travas‐Sejdic Jadranka 
Published: November 2011

AbstractComposite hollow microspheres consisting of polyaniline (PANI) and indomethacin (IND) are prepared through a self‐assembly process in a mixed methanol/water solutions. Different volume fractions of methanol to water and different aniline concentrations are investigated to obtain the optimal conditions for the formation of PANI/IND composite hollow microspheres. The morphologies of the PANI/IND composites are characterized, showing the inner hollow center of the microspheres. Spectroscopic characterizations reveal that the synthesized materials have many typical features of chemically synthesized PANI and confirm the presence of IND in the composites. A controlled release of IND is achieved by adjusting the pH value of the buffer solution.

Polymer–TiO2 composite nanorattles via RAFT‐mediated emulsion polymerization
Authors: Nguyen Duc , Such Chris , Hawkett Brian 
Published: November 2011

AbstractIn this work, successful synthesis of polymer nanorattles containing titanium dioxide pigment particles in the centers of air voids is reported. The method used amphiphilic macro‐RAFT copolymers as stabilizers for pigment dispersion and the subsequent encapsulation of the pigment with polymer. The particles were first encapsulated by a water swellable hydrophilic layer, followed by a hard hydrophobic layer. Nanorattles were formed by swelling of hydrophilic polymer layers on the surface of the encapsulated pigment particles in a basic solution at elevated temperature. After swelling, the outer hard polymer shell was crosslinked to improve its strength. Air void sizes of the nanorattles were found to be controlled by swelling time, temperature, and the hydrophilic polymer layer thickness. © 2011 Wiley Periodicals, Inc.

Exhaustive and partial alkoxylation of polymethylhydrosiloxane by copper‐catalyzed dehydrocoupling with alcohols: Synthesis, crosslinking behavior, and thermal properties of the products
Authors: Iinuma Ryosuke , Narsi Reddy Poreddy , Hayashi Teruyuki , Tanaka Masato 
Published: November 2011

AbstractPolymethylhydrosiloxane (PMHS) reacts with aliphatic and aromatic alcohols at room temperature in the presence of [CuH(PPh3)]6 complex catalyst to give poly[(methyl) (alkoxy)siloxane]s in high yields. Reactivity of alcohols decreases in the order of p‐methoxyphenol > p‐cresol > phenol > benzyl alcohol > allyl alcohol > ethanol > isopropanol > tert‐butyl alcohol. Partially p‐cresylated polymers, which still retain unreacted SiH bonds, react further with ethylene glycol or water to form cross‐linked polymers, which, depending on the extent of cross linking, gelate during the cross‐linking process. Propargyl alcohol reacts with PMHS very rapidly to give exhaustively and partially propargyloxylated PMHS. Resulting polymers, upon heating, undergo crosslinking. Partially propargyloxylated polymers display high thermal stability [Td5 (temperature of 5% weight loss) > 500 °C] as compared with starting PMHS (243 °C) and exhaustively propargyloxylated one (414 °C). © 2011 Wiley Periodicals, Inc.

Published: November 2011

AbstractA new synthetic strategy for polymers containing amino acids in the main chain was developed. Monomers N‐oxetanylalanine (N‐Oxe‐Ala‐COOH), N‐oxetanylglutamic acid (N‐Oxe‐Glu‐COOH), and N‐oxetanyllysine (N‐Oxe‐Lys‐COOH) containing both oxetanyl and carboxyl groups were synthesized, and self‐polyaddition and self‐copolyaddition of these monomers afforded the corresponding polymers containing amino acids in the main chain [poly(OxAla), poly(OxLys), poly(OxGlu), poly(OxAla‐co‐OxGlu), poly(OxGlu‐co‐OxLys), and poly(OxAla‐co‐OxLys)] with molecular weight in the range of 920–6620, in satisfactory yields. The physical properties, such as solubility, glass transition temperature, and thermal stability, were consistent with the amount of carboxyl groups at the chain ends. Biodegradability of the polymers was examined by the biochemical oxygen demand method; the decomposition ratios of poly(OxAla) and poly(OxAla‐co‐OxGlu) were about 60%, whereas that of poly(OxGlu) was nearly 100% after 28 days. © 2011 Wiley Periodicals, Inc.
