OSMANLI İKTİSAT ZİHNİYETİNDE KAMU HİZMETLERİNİN YERİNE GETİRİLMESİ VE VAKIFLAR
Authors: ÖZTÜRK Rahime Hülya
Published: January 2019

Vakıflar Osmanlı iktisadi ve

sosyal yaşamında pek çok görevi yerine getiren kurumlar olmuştur. Fetihlerle

topraklarını genişletmeyi amaçlayan devlet ordunun ihtiyaçları için önemli

askeri harcamalar yaparken kamusal hizmetleri gerçekleştirme görevini vakıflara

devretmiştir. Padişahların bizzat kendileri, eşleri, çocukları ve önemli devlet

görevlileri tarafından pek çok vakfın kurulduğu, vakıfların toplumsal yaşamda

yaygınlaşması için vakıf kurulmasının desteklendiği görülmektedir. Kuruluş

amaçları açısından farklılık gösteren vakıfların odak noktası ekonomik

sorunların giderilmesini sağlamak ve yardımlaşmayı teşvik etmektir. Vakıfların

en önemli özelliği ise devletin yerine getirmesi gereken kamu hizmetlerini

üstlenmiş olmasıdır. Herhangi bir altyapı ya da bayındırlık hizmetinin yerine

getirilmesinde vakıflar doğrudan rol almıştır. Tüm bu nitelikleri nedeniyle

vakıflar Osmanlı

iktisadi ve sosyal yaşamında önemli bir kurum olarak varlıklarını

sürdürmüşlerdir. Bu çalışmanın birinci bölümünde Osmanlı Devleti’nde vakıfların

önemi üzerinde durulmuştur. İkinci bölümde vakıfların kuruluş şekilleri ve

vakıfların ekonomik boyutu ele alınmıştır. Üçüncü ve son bölümde ise para

vakıflarının yapısı ve ekonomik etkileri ortaya konmaya çalışılmıştır.

İşletmeler,

hissedar değerlerinin korunmasını ve güçlendirilmesini sağlamak için dengeli

puan kartı (DPK) ile değer yaratma sürecini kontrol ederlerken, risk yönetimi

ile de değer kaybının önlenmesini sağlamaktadırlar. Her iki yönetimsel sürecin

birbirlerinin eksikliklerini gidererek daha etkin bir araç olmalarını sağlamak için,

biçimsel bir şekilde entegre edilerek yürütülmeleri gerektiğine dair çeşitli araştırmacılar

tarafından tavsiyelerde bulunulmuş ve çeşitli kavramsal yöntemler geliştirilmiştir.

Ancak işletmeler için, önerilen bu yöntemler arasından hangisinin daha uygun

olacağının ayrıntılı bir şekilde incelenmesi ve araştırmacılar için ise ileride

geliştirilecek yeni kavramsal yöntemlere ışık tutacak önerilerde bulunulması

gerekmektedir. Bu sebeple bu çalışmada, ilgili literatürdeki araştırma

eksikliğinin giderilmesine katkı sağlamak amacıyla risk yönetimini DPK’ye

entegre eden alternatif yaklaşımlar incelenmiş ve bu yaklaşımların birbirleri

üzerindeki artı ve eksilerinin neler olduğu tartışılmıştır. Yapılan incelemeler

doğrultusunda en iyi alternatif yöntemin, stratejik hedeflere bağlı birleşik

bir risk faktörünün her bir boyut için geliştirilmesiyle ve ayrıca strateji

haritasında yer alan finansal boyut içerisine üçüncü bir strateji teması olarak

risk yönetimi stratejisinin eklenmesiyle elde edileceği düşünülmektedir.

Published: January 2019

In a recent publication on nomenclature and taxonomy of the genus Juno, we have established several new combinations for irises, including Iris koyuncui Fırat. When stating the intended new combination in Juno for the latter name, a partially wrong citation of its basionym was made. Although the publication year, page number and holotype data were correctly and fully indicated for that basionym, the Fırat’s paper referenced in the literature list to justifiy the basionym citation was indeed a different one in the same journal, which however concerned another taxon from the same area, Iris zagrica Mathew & Zarrei subsp. hakkariensis Fırat, and not the basionym of Iris koyuncui. In the present contribution, evidence is shown to regard the incorrect citation of the place of publication of the basionym as a correctable error not affecting valid publication of the combination, which is fixed here to be cited as J. koyuncui (Fırat) M.B.Crespo, Mart.-Azorín & Mavrodiev.
Revision of the larval morphology (Zoea I) of the family Hippolytidae (Decapoda, Caridea), with a description of the first stage of the shrimp Hippolyte obliquimanus Dana, 1852

Published: January 2019

The aim of this study was to summarize the available data on larval morphology of the first zoea of the family Hippolytidae and describe the first zoeal stage of H. obliquimanus from two geographically distinct populations, Brazilian and Caribbean in order to discuss interand intraspecific variability. Ovigerous females of Hippolyte obliquimanus were collected at Cahuita (Limón, Costa Rica) and at Ubatuba (São Paulo, Brazil). We compiled the published descriptions of all available hippolytid Zoea I (66 spp., 21%), and all zoeae share several characteristics. However, such morphological features cannot be used to distinguish the first zoeae of Hippolytidae from other caridean larvae. Historically, the presence of an exopodal seta at the maxillule and the absence of the anal spine/papilla have been considered as characteristic for the Zoea I of the genus Hippolyte. The results of our revision, however, did not support these conclusions: although H. obliquimanus showed an exopodal seta at the maxillule, four congeners did not bear such structure; moreover, H. obliquimanus as well as one other congener have an anal spine/papilla. All morphological characters observed in the first zoeal stage of H. obliquimanus are shared with others species of the family Hippolytidae. Intraspecific variability in Hippolyte obliquimanus was detected in one morphological aspect: the first zoea had four denticles on the ventral margin of the carapace in the Brazilian population, while specimens from the Costa Rican population had three.
A new species of Parasyrisca Schenkel, 1963 (Araneae, Gnaphosidae) from the Altai
Authors: MARUSIK YURI M. , FOMICHEV ALEXANDER A.
Published: January 2019

Parasyrsca is a Holarctic gnaphosid genus which currently includes 46 species (Platnick, 2010). Although it is found both in the Palaearctic and Nearctic only one species is known from the Western Nearctic, P. orites (Chamberlin & Gertsch, 1940). The majority of species occur in the mountains of Central Asia, South Siberia, and the Caucasus. The genus is relatively well studied due to revision by Ovtsharenko et al. (1995), which included 44 species. During the 15 years that have passed since that revision, four species have been described from China, the Crimea and Hungary (Tang & Zhao 1998; Kovblyuk 2003; Marusik & Fritzén 2009; Szinetár et al. 2009). While studying the fauna of the Altai we found specimens that belonged to an undescribed species. The goal of this paper is to provide a detailed description of this new species.
Redescription of the African Chordodes albibarbatus Montgomery 1898, and description of Chordodes janovyi n. sp. (Gordiida, Nematomorpha) and its non-adult stages from Cameroon, Africa
Authors: BOLEK MATTHEW G. , SCHMIDT-RHAESA ANDREAS , HANELT BEN , RICHARDSON DENNIS J.
Published: January 2019

We redescribe Chordodes albibarbatus Montgomery 1898 from the original holotype male and the originally described female specimen using Nomarski interference contrast microscopy. Our reinvestigation indicates that C. albibarbatus is sexually dimorphic and contains five types of areoles in the male and six types of areoles in the female. Our reinvestigation of C. albibarbatus indicates that it is a distinct species, and is most similar to the African Chordodes gariazzi Camerano 1902 and Chordodes heinzei Sciacchitano 1937, all of which share simple “blackberry”, bulging, tubercles, and thorn areoles. In addition, we describe adult free-living male and female Chordodes janovyi n. sp. collected from West Province, Cameroon, Africa using both morphological (light and scanning electron microscopy) and molecular data, and designate types for this species. Chordodes janovyi belongs to a large group of Chordodes in which simple areoles are smooth or superficially structured less so than “blackberry” areoles. Present among the simple areoles are clusters of crowned and circumcluster areoles along with thorn and tubercle areoles, whereas bulging areoles are absent. We also describe the egg strings, eggs, larvae, cysts, and oviposition behavior of C. janovyi and compare these non-adult life stages to other nematomorph genera and species for which such life cycle stages are known, and we discuss the use of non-adult stages and the use of molecular tools in future studies of nematomorph systematics and biodiversity.
Two new species of Ameroidea (Acari: Oribatida) from Madagascar
Authors: MAHUNKA SÁNDOR
Published: January 2019

Two new oribatid mite species, Hymenobelba exclamationis and Pteramerus clypeatus spp. nov. (Ameridae), are described and illustrated based on specimens collected from mossy montane rainforest in the Malagasy Republic, Toamasina Province, Maromizaha forest. Both of them show a great variation of peculiar morphological features as having or not the costuliform prodorsal structure, the number and position of the notogastral setae and the abundance or position of aggenital and adanal neotrichy in genus Hymenobelba. A well observable variation can be observed in the form of pedotecta and in legs segments of the other species (Pteramerus clypeatus), which is only the second species belonging to this genus.

Two new species of the genus Uenoites Belousov et Kabak, 2016 from mountains of Myanmar (Coleoptera: Carabidae: Trechini)
Authors: BELOUSOV IGOR A. , KABAK ILYA I. , SCHMIDT JOACHIM
Published: January 2019

Two new species of ground beetles of the genus Uenoites Belousov et Kabak, 2016 (tribe Trechini) are described from mountains of northern Myanmar: U. reuteri sp. n., and U. tibialis sp. n.. There are the first members of the genus found outside Yunnan Province of China. The taxonomic position of the new species within the genus is discussed based on the relevant character states in external and genital morphology. Both newly described species are closely related to each other and seem to form a distinct species-group within extremely diverse genus Uenoites. Externally, the newly described species are much more similar to very large members of the genus Queinnectrechus Deuve, 1992, than to most Uenoites but differs in an increased number of elytral setiferous pores in stria 3 and in the presence of the preapical pore.

Surgical Therapy of Peri-Implantitis with Local Minocycline: A 6-Month Randomized Controlled Clinical Trial
Authors: Cha J.K. , Lee J.S. , Kim C.S.
Published: January 2019

The purpose of this study was to determine the clinical, microbial, and radiographic effects of local minocycline combined with surgical treatment of peri-implantitis. Fifty patients with peri-implantitis were recruited, and surgical treatment with the local application of either minocycline or placebo ointment was performed. The application of minocycline was repeated with supragingival debridement at 1, 3, and 6 mo postoperatively. Plaque index, gingival index (GI), probing pocket depth (PPD), and bleeding/suppuration on probing were measured at baseline and 1-, 3-, and 6-mo evaluations. The change in supporting bone level (SBL) measured with cone beam computed tomography was analyzed between baseline and 6 mo. Microbial analysis was performed with real-time polymerase chain reaction. Both groups exhibited improvements in clinical and radiographic measurements after surgical treatment. There was a significant difference in the changes of mean PPD between the test and control groups (2.68 ± 1.73 and 1.55 ± 1.86 mm, respectively, P = 0.039). The changes of mean GI and SBL differed significantly between the groups (ΔGI: 0.83 ± 0.60 and 0.40 ± 0.68; ΔSBL: 0.72 ± 0.56 and 0.31 ± 0.49 mm, respectively, P = 0.026 and 0.014). Treatment success rates (defined as PPD <5 mm, absence of bleeding/suppuration on probing, and no further bone loss) were 66.7% and 36.3% in the test and control groups, respectively. The count of red complex bacteria tended to decrease in both groups until 6 mo; however, no significant intergroup difference was found. None of the patients in the test group carried Porphyromonas gingivalis or Tannerella forsythia at 6 mo. These findings indicate that the repeated local delivery of minocycline combined with surgical treatment provides significant benefits in terms of clinical parameters and radiographic bone fill, with a higher treatment success rate in the short healing period (cris.nih.go.kr KCT0002844).

Published: January 2019

Ineffective oral wound healing is detrimental to patients’ oral health–related quality of life. Delineating the cellular mechanisms involved in optimal healing will elicit better approaches to treating patients with compromised healing. Osteal macrophages have recently emerged as important positive regulators of bone turnover. The contributions of macrophages to long bone healing have been studied, but their role in oral osseous wound healing following tooth extraction is less clear. Clodronate-loaded liposomes were used as a tool to deplete macrophages in C57BL/6J mice and assess oral osseous bone fill after extraction. In addition to macrophage ablation, osteoclast ablation occurred. Interestingly, depletion of macrophages and osteoclasts via clodronate treatment had differential effects based on skeletal location. In the nonwounded tibiae, clodronate treatment significantly increased CD68+ cells and decreased F4/80+ cells in the marrow, which correlated with increased trabecular bone volume fraction after 7 and 14 d. Serum formation and resorptive markers P1NP and TRAcP 5b were decreased as were tibial TRAP+ osteoclasts. In healing extraction sockets, clodronate treatment increased extraction socket trabecular bone thickness at 14 d, which correlated with decreased TRAP+ osteoclasts and F4/80+ macrophages. Conversely, nonwounded maxillary interseptal bone was unaffected by clodronate treatment. Furthermore, the increase in extraction socket bone fill with clodronate was less than the large increase in trabecular bone observed in a nonwounded long bone. These data suggest a temporal and spatial specificity in the roles of macrophages and osteoclasts in normal turnover and healing.

Published: January 2019

Military veterans comprise a significant demographic that is adding to the diversity of the U.S. federal workforce. Using data from the 2015 Federal Employee Viewpoint Survey, this study examined the relationship between organizational inclusion, human resource practices, trust in leadership, and organizational commitment among military veterans and nonveterans in federal agencies. Structural equation modeling showed the positive impact of organizational inclusion and human resource practices on organizational commitment was partially mediated by trust in leadership. Human resource practices had a greater impact than organizational inclusion on organizational commitment. Human resource practices, however, had less of an impact on organizational commitment and trust in leadership among military veterans as compared with nonveterans. Organizational inclusion had more of an impact on trust in leadership among the military veterans than the nonveterans in the study. There was no difference based on veteran status regarding the impact of trust in leadership on organizational commitment.
Voting After Violence: How Combat Experiences and Postwar Trauma Affect Veteran and Voter Party Choices in Croatia’s 2003 Postwar Elections
Authors: Lesschaeve Christophe
Published: January 2019

This article investigates the role of war experiences on voters and veterans’ party choices in postwar elections. The literature has looked at the relation between military experience and electoral behavior, and at the political consequences of war-related psychological distress, yet has never integrated the two. This article looks at the war experiences and specifically the development of war trauma on the likelihood of casting a vote for a nationalist party during a postwar election. Based on a 2003 survey of 1,000 Croatian voters, I find that veterans of Croatia’s war of independence are more likely to vote for nationalist parties. However, voters who showed signs of trauma were less likely to vote for these parties. In addition, veterans suffering from psychological trauma after the war were far less likely to vote for nationalist parties.
Recognition of voltage sag causes using fractionally delayed biorthogonal wavelet
Authors: Saini Manish Kumar , Kapoor Rajiv , Beniwal Rajender Kumar , Aggarwal Akanksha
Published: January 2019

In this work, a new fractionally delayed biorthogonal wavelet is designed for recognition of voltage sag causes. This work addresses the classification of voltage sag causes into three categories, i.e., fault events (namely line-to-ground fault, line-to-line fault, double-line-to-ground fault and symmetrical fault), induction motor starting and transformer energization. Fractionally delayed biorthogonal Coiflet wavelet of order 2 (named as Coiflet fraclet) is designed using Lagrange interpolation and employed for the multiresolution analysis of voltage sag signals. To achieve higher classification accuracy, event information is derived from both time-frequency domain and frequency domain. Frequency information is obtained by applying multiple signal classification (MUSIC) algorithm on voltage sag signals. Both the time-frequency domain and frequency domain features are concatenated to implement the feature level fusion for strengthening the feature set. The feature set obtained after feature level fusion is used for training the recursive reduced kernel based extreme learning machine which addresses the problem of highly complex structure due to huge dataset of large dimensions. The classifier has shown robustness to the presence of noise also and classified the voltage sag causes with high accuracy.
Solitary Nasal Schwannoma Clinically Presenting as an Angiofibroma of the Nasopharynx
Authors: Gupta S.C. , Sachin Jain , Savyasachi Saxena , Ritesh Jaiswal , Neha Garg , Singh Himanshu P.
Published: January 2019

Benign schwannomas of the nasal cavity are rare. When they do occur, their clinical presentation is variable, and some are fairly vascular. We report the case of a 17-year-old boy who presented with epistaxis associated with a unilateral nasal mass that extended into the nasopharynx. The tumor was removed via a transpalatal approach. In most such cases, a clinical diagnosis of angiofibroma is made. In this case, however, histopathologic examination identified the lesion as a schwannoma.
Therapeutic Approaches to Complicated Cholesteatoma of the External Auditory Canal: A Case of Associated Facial Paresis
Authors: Belcadhi Malek , Chahed Houda , Mani Radhouane , Bouzouita Kamel
Published: January 2019

Spontaneous cholesteatoma of the external auditory canal (EAC) is an uncommon condition that is difficult to diagnose. In a patient with such a possibility, serious clinical investigation along with radiologic and histologic exploration should be performed early on because a delay in treatment can lead to severe complications. Given the rarity of EAC cholesteatoma, no therapeutic consensus has emerged. The type of management depends on the extensiveness of invasion and bone erosion and the status of the neighboring structures. The primary therapeutic objectives are to eradicate the cholesteatoma and then to fill in the residual cavity, which in our opinion can be best accomplished with a muscle flap and EAC reconstruction. Postoperative follow-up should be carried out to look for infections, stenosis, and recurrence. We report a new case of spontaneous EAC cholesteatoma, and we review its diagnostic and therapeutic challenges.

Sebaceous Lymphadenoma: A Case Report and Review of the Literature
Authors: While Benjamin , Whiteside Olivia J.H. , Desai Vijayadwaja , Gurr Paul
Published: January 2019

An 80-year-old woman presented with a mass in her left parotid region. An ultrasound-guided core biopsy showed sebaceous glands with lymphoplasmacytic infiltration. Magnetic resonance imaging displayed a well-circumscribed lesion within the left parotid gland. The mass was completely excised, and the patient made a full recovery. Sebaceous lymphadenomas of the salivary glands are rare, benign tumors that are effectively treated by complete excision. The challenge that these tumors present lies in their accurate diagnosis. Because of their histologic similarity to related malignant tumors, such as mucoepidermoid carcinomas and sebaceous lymphadenocarcinomas, mis-diagnosis could lead to unnecessarily radical treatment. We highlight the need for careful clinical and histologic diagnosis in tumors of the salivary glands.
Primary Carcinoid Tumor of the Frontal Sinus: A Case Report
Authors: Chu Michael W. , Karakla Daniel W. , Silverberg Marc , Han Joseph K.
Published: January 2019

Carcinoid tumors are rare, indolent, neuroendocrine tumors that are most commonly found in the gastrointestinal tract and lungs. They occasionally develop in the head and neck, either as a primary tumor or, more commonly, as a metastasis. The most common sites of head and neck carcinoids are the larynx and middle ear. Only a few cases of carcinoid in the nasal cavity and paranasal sinuses have been reported. We describe a case of primary typical carcinoid of the frontal sinus in a 61-year-old man, and we review the clinical, imaging, surgical, and histochemical findings in this case. The patient was treated with endoscopic resection. A subsequent workup for metastatic and occult primary disease was negative, confirming that the frontal sinus was the primary source. At follow-up 12 months postoperatively, the patient remained without disease. To the best of our knowledge, this is the first report of a primary typical carcinoid tumor originating in the frontal sinus.
Aspiration of Radiolucent Dentures in Facial Trauma: Case Report
Authors: Chadwell Jon B. , Mitchell Joshua R. , Donnino Michael , Peterson Charles , Guentert Paul , Arnold Cliff , Walsh Mark
Published: January 2019

Foreign body aspiration is a serious problem that may lead to complications or even death. People who sustain major maxillofacial trauma can often damage their teeth or oral prostheses, and aspiration can occur. Detection of this type of aspiration can be difficult, especially in elderly people wearing dental appliances, since many dental prostheses are not radiopaque and the aspiration is not always recognized at the time of injury. We report a specific case of extensive maxillofacial trauma from a self-inflicted gunshot wound leading to aspiration of large, radiolucent denture fragments, delayed diagnosis, and complications. The possibility of denture fragment aspiration must always be part of the differential diagnosis in an elderly trauma patient presenting with dyspnea, hypoxia or, eventually, pneumonia. This is especially so when radiologic evaluation does not reveal a foreign body, since much dental prosthesis material is radiolucent. Delayed complications of radiolucent dentalprosthesis aspiration could be avoided by the inclusion of some radiopaque material within the acrylic material of the prosthesis.
Oropharyngeal Plasmablastic Lymphoma in a Man with Human Immunodeficiency Virus Infection: A Case Report
Authors: Rajaram Sowmya T. , Lobo Flora D. , Achary Chandrayya
Published: January 2019

Oropharyngeal lymphomas are rare, typically high-grade neoplasms. We describe a case of plasmablastic lymphoma that originated in the oropharynx of a 40-year-old man who was positive for human immunodeficiency virus (HIV). The diagnosis was based on fine-needle aspiration cytology of the mass followed by histopathologic examination supplemented with immunophenotyping. The mass was excised, but the patient refused antiretroviral therapy, and he died within 6 months of the diagnosis. In HIV-positive patients, non-Hodgkin lymphomas frequently involve sites, including the oropharynx, that are unusual in patients without HIV.

Published: January 2019

Almost all aural cholesterol granulomas develop in the mucosa of the middle ear. We describe the case of a 14-year-old girl who presented with an asymptomatic, nontender, dark-blue, cystic lesion in the posteroinferior portion of the left ear canal. The mass was excised via a postauricular approach. Postoperatively, the mass was identified as a cholesterol granuloma on pathologic examination. To the best of our knowledge, this is the first reported case of a human cholesterol granuloma limited to the external ear canal.
Cervical Hibernoma, a Rare, Benign Tumor: Case Report
Authors: Prendes Brandon L. , Kohli Chitra , Brooks John S.J. , Newman Jason G.
Published: January 2019

Hibernomas are rare, benign tumors that contain neoplastic cells that are histologically similar to those of brown adipose tissue. The most common sites of these tumors have been the back and thighs; head and neck involvement has been rare. We describe the case of a 54-year-old woman who presented with a 1-year history of a large, asymptomatic, lateral neck mass. Based on imaging findings and fine-needle aspiration cytology, a hibernoma was suspected, although a liposarcoma could not be ruled out prior to surgery. The mass was completely resected. On postoperative analysis, the tumor was grossly and microscopically consistent with a cervical hibernoma. Although hibernomas are rare, they are important entities and should be considered in the differential diagnosis of a soft-tissue mass of the head or neck.
Acute Parotitis Induced by Trimethoprim/Sulfamethoxazole
Authors: Patel Jayna S. , Scheiner Edward D.
Published: January 2019

Adverse drug reactions to the sulfonamide antibiotics are uncommon. When they do occur, they usually manifest as a rash or urticaria. Our review of the recent literature found that while sialadenitis is listed as a possible side effect of sulfonamide use, no actual case has ever been reported until now. We describe a case of acute bilateral parotitis that arose as a side effect of sulfonamide antibiotic treatment. We also examine the relevance of such pathology to the proposed mechanisms of sialadenitis, and we briefly discuss sulfonamide-induced pancreatitis. Lastly, we review the controversy over the possibility that some adverse drug reactions may be caused by cross-reactivity among different classes of sulfonamides.

Published: January 2019

Papillary cystadenocarcinoma is a rare malignant neoplasm of the salivary glands. This tumor most commonly arises in the major salivary glands, mainly in the parotid gland, and rarely metastasizes to regional lymph nodes. We report here a case of papillary cystadenocarcinoma originating from a minor salivary gland, localized in the lateral portion of the tongue and with neck metastases, in a 57-year old woman. We discuss histopathologic and clinical features of this lesion and review the literature.

Sinonasal fibrosarcoma is an infrequently occurring malignant neoplasm. It usually presents with nasal obstruction and epistaxis, as do other sarcomas in this region. The final diagnosis is based on the histopathologic and immunohistochemical examination. We report a case involving a 47-year-old woman with a 2-year history of left nasal obstruction and proptosis, as well as diplopia for the 2 months preceding her visit. Computed tomography and magnetic resonance imaging showed a neoplasm occupying the left nasal cavity, ethmoid sinuses, and bilateral frontal sinuses. The neoplasm also was eroding the medial wall of the maxillary sinus, the lamina papyracea, the cribriform plate, and the anterior wall of the frontal sinus. Complete removal of the tumor was achieved both endoscopically and through a Lynch incision. Sinonasal fibrosarcoma was found on histopathologic examination.

The cases of 80 patients who underwent Caldwell-Luc surgery for the treatment of chronic rhinosinusitis between 2002 and 2007 at Vanderbilt University Medical Center's Department of Otolaryngology were reviewed. Data on demographics, comorbidities, details of surgery, surgical pathology, and histology were collected. These data were compared with those of 40 patients who underwent standard functional endoscopic sinus surgery in 2007. Statistically significant differences were found in terms of mean patient age, sex, mean number of sinuses surgically addressed, number of prior surgeries, and tissue eosinophil counts. Microscopic examination revealed the presence of “necrotic bone” in 2 Caldwell-Luc specimens, and “necrotic debris” in 2 other Caldwell-Luc specimens. No similar finding was seen in the control group. Caldwell-Luc is a surgery of last resort for patients who fail aggressive interventions for maxillary sinus disease. The mucosal lining of this small group of patients appears to be different from that of patients who respond favorably to functional endoscopic sinus surgery.

Ectopic eruption of a tooth is common in the dental arch, palate, and nose, but it is rare in the maxillary antrum. We present the case of a 35-year-old man with an ectopic canine and an associated dentigerous cyst in the maxillary sinus that masqueraded as an antrochoanal polyp.
Nasopharyngeal Dendritic Cell Sarcoma, Not Otherwise Specified, in a 34-Year-Old Man
Authors: Horton William B. , Joyner David A. , Daley William P. , Pitman Karen T. , Khan Majid A.
Published: January 2019

Dendritic cell sarcoma, not otherwise specified (NOS), is an entity that is poorly defined because of its rarity and poorly understood pathogenesis. It is characterized by positive immunohistochemical staining for S-100 and CD1a, along with an absence of cytoplasmic Birbeck granules on electron microscopy. We report the case of a surgically inaccessible nasopharyngeal dendritic cell sarcoma, NOS, in a 34-year-old man. Treatment with chemotherapy along with adjuvant radiation therapy was successful in decreasing the size of the nasopharyngeal mass, and the patient remained free of any evidence of recurrence nearly 5 years after treatment.
Retropharyngeal Abscess from an Unusual Organism—Kingella Denitrificans—in a Patient on Low-Dose Methotrexate
Authors: Rajanna Divya M. , Manickavasagam Jaiganesh , Jewes Linda , Capper Ruth
Published: January 2019

Retropharyngeal abscess can be a life-threatening emergency with potential for airway compromise. We report a case of retropharyngeal abscess caused by Kingella denitrificans in a 66-year-old Caucasian man taking low-dose methotrexate for psoriatic arthritis. K denitrificans has not been previously reported as a cause of retropharyngeal abscess. K denitrificans, along with other Kingella species, is often found to be part of the normal upper respiratory tract flora. Potentially life-threatening complications of retropharyngeal abscess can occur in immunocompromised patients. Although complications of immunosuppression are thought to be rare with the use of low-dose pulse methotrexate for non-neoplastic conditions, such complications with prolonged use of low-dose pulse methotrexate may be seen.

Published: January 2019

Soft-tissue sarcomas arising in the skin of the external ear have a better prognosis than might be expected based on the behavior of other sarcomas. Currently there are a few major case series analyzing soft-tissue sarcomas and the factors related to their prognosis. The purpose of this study was to determine the behavior of these tumors and attempt to define factors affecting prognosis. We extracted data from the Surveillance Epidemiology and End Result (SEER) 17 Registry and identified a total of 297 patients with sarcoma of the external ear who were included in the registry from 1973 to 2004. Of these, 176 (59.3%) patients were diagnosed with malignant fibrous histiocytoma. Dermatofibrosarcoma was the second most prevalent soft-tissue sarcoma (56 patients; 18.9%), followed by leiomyosarcoma (27 patients; 9.1%). The overall 5-year survival rate of patients with all histologic types of STS of the external ear was 78.5%.
Changes in Intramaxillary Sinus Pressure following Antrostomy, Draining Tubes, and YAMIK Procedures in 25 Patients Treated for Chronic Paranasal Sinusitis
Authors: Miwa Masato , Miwa Mayumi , Watanabe Kensuke
Published: January 2019

When conservative therapies are not effective in treating sinus infections, alternate steps can be taken to improve paranasal cavity ventilation. These measures may include surgical procedures such as intranasal endoscopic or maxillary sinus fenestration, and other procedures such as placement of a maxillary sinus tube or a YAMIK sinus catheter. We conducted a prospective study of 25 patients to investigate the effects on the nasal mucosa of improved ventilation between the nasal and paranasal cavities. We accomplished this by comparing (1) the results of simultaneously measured nasal cavity and intramaxillary sinus pressures before and after widening of ventilation openings, (2) changes in mucociliary transport function as measured by the saccharin test, and (3) changes in nasal airway resistance. Just as multiple transit routes between the nasal cavity and maxillary sinus give rise to greater fluctuations in intramaxillary sinus pressure, and just as rapid breathing gives rise to even greater pressure fluctuations than does quiet breathing, we believe that both intranasal cavity airflow velocity and the number of ventilation openings present have an effect on the state of ventilation between the nasal cavity and maxillary sinus. We also suggest that the establishment of maxillary sinus ventilation openings improves mucociliary clearance.

Allergic fungal rhinosinusitis (AFRS) is the most common form of fungal sinus disease. Its recurrence rate is high despite numerous strategies to prevent it. We conducted a study to assess the effect of systemic and topical antifungal agents—both separately and in combination—in preventing recurrence of AFRS following functional endoscopic sinus surgery (FESS). Our initial study population was made up of 50 adults who were diagnosed with AFRS by clinical, radiologic, histopathologic, and laboratory workup and who subsequently underwent FESS. Postoperatively, these patients were randomized into 5 different treatment groups matched for sex, age, and socioeconomic status. Four of the groups received a different antifungal regimen in addition to convenient medical treatment (CMT), while a fifth group served as a control. The antifungal regimens included oral itraconazole (group A), fluconazole nasal spray (group B), combined oral itraconazole and nasal fluconazole (group C), and irrigation with a fluconazole solution through the nasal fossa (group D); the group of 10 controls (group E) received CMT only. A total of 41 patients were available for follow-up (9 mo maximum). Recurrence rates in the 5 groups were 66.7, 10.0, 14.3, 28.6, and 75.0%, respectively. Based on our findings, we conclude that treatment with topical fluconazole as either a nasal spray or an irrigation solution can significantly reduce the rate of recurrence of AFRS after FESS.

Nasal injuries are among the most common sports injuries. We conducted a prospective, observational study of 91 patients, aged 7 to 60 years (mean: 18.3), who had sustained a nasal injury while engaging in a sport, exercise, or other recreational physical activity. We found that a substantial proportion of these injuries occurred in females (29.7% of cases). A high percentage of injuries (86.8%) occurred in those who had been participating in a noncontact sport; the sport most often implicated was basketball (26.4%). Also, injuries were more common during organized competition as opposed to recreational play (59.3 vs. 40.7%). Of the 91 nasal injuries, 59 (64.8%) were fractures, most of which were treated with a closed reduction. Almost all of the patients in this study (92.3%) were able to return to their sport. We conclude that most sports-related nasal fractures are not preventable.
Return to Contact Sports following Infectious Mononucleosis: The Role of Serial Ultrasonography

Published: January 2019

Splenic rupture is a rare but potentially fatal complication of infectious mononucleosis. Athletes returning to contact sports following infectious mononucleosis are at potential risk of splenic rupture secondary to abdominal trauma. No clear consensus exists as to when it is safe to allow these athletes return to contact sports. Suggested periods of abstinence have ranged from 2 weeks to 6 months. We outline our experiences with the use of abdominal ultrasonography at 1 month after the diagnosis of infectious mononucleosis as a means of determining when athletes can safely return to contact sports. Our study group was made up of 19 such patients (mean age: 16.7 yr). We found that 16 of these patients (84%) had normal splenic dimensions on ultrasonography 1 month after diagnosis, and they were therefore allowed return to contact sports. While the remaining 3 patients had an enlarged spleen at 1 month, their splenic dimensions had all returned to normal when ultrasonographic examination was repeated at 2 months postdiagnosis. We conclude that serial abdominal ultrasonography allows for informed decision making in determining when athletes can safely return to contact sports following infectious mononucleosis.
Nonattendance at a Hospital-Based Otolaryngology Clinic: A Preliminary Analysis within a Universal Healthcare System

Published: January 2019

Missed appointments at specialty clinics generate concerns for physicians and clinic administrators. Appointment nonattendance obstructs the provision of timely medical interventions and the maximization of systemic efficiencies. Yet, empiric study of factors associated with missed appointments at adult specialty clinics has received little attention in North America. We conducted a preliminary study of otolaryngology clinic nonattendance in the context of a universal healthcare system environment in Canada. Our data were based on the schedule of 1,512 new patient appointments at a hospital-based clinic from May 1 through Sept. 30, 2008. Gathered information included the employment status of the attending physician (i.e., full-time vs. part-time), the patients sex and age, the day of the week and the time of the appointment, and the attendance status. We found that the rate of nonattendance was 24.4% (n = 369). Nonattendance rates varied significantly according to physician employment status (more common for part-time physicians), patient sex (women) and age (younger adults), and the day of the appointment (Wednesdays), but not according to the time of day. Our findings suggest that there are predictable patient and systemic factors that influence nonattendance at medical appointments. Awareness of these factors can have implications for the delivery of healthcare services within a universal healthcare context.

Published: January 2019

Schwannomas arising from the cochlear nerve and confined to the internal auditory canal are rare. Clinically, a cochlear schwannoma can cause a progressive hearing loss. We report the case of a 56-year-old woman with a cochlear schwannoma that manifested as a slowly progressive hearingloss. The lesion was diagnosed by gadolinium-enhanced 3-Tesla magnetic resonance imaging.
Primary Mucosal Desmoplastic Melanoma of the Nasal Vestibule: The Second Case
Authors: Cervantes Sergio S. , Baugh Reginald
Published: January 2019

Primary mucosal desmoplastic melanoma is an exceedingly rare, potentially devastating disease that is often initially misdiagnosed because of its deceptively benign presentation. We report what we believe is only the second case of mucosal desmoplastic melanoma arising from the nasal vestibule. The patient, a 62-year-old woman, presented with an obstructive, enlarging mass in the nasal cavity. The tumor, which was initially believed to be benign, was excised, but it recurred 12 months postoperatively. The recurrence was excised, but 4 years later, the patient experienced a second recurrence; in this case, the tumor had invaded the cribriform plate and extended to the anterior cranial fossa. The tumor subsequently metastasized to the dura mater, which led to the patient's death. We review the distinction between conventional mucosal melanoma and mucosal desmoplastic melanoma, and we discuss the ways in which the behavior of a desmoplastic melanoma can point to the diagnosis. Because a diagnosis can be difficult to establish, we stress the importance of maintaining a high index of suspicion when evaluating pathologic and immunohistochemical findings in a patient with a recurrent mucosal nasal mass.

Published: January 2019

Pharyngocele, or lateral pharyngeal diverticulum (LPD), is rare, as only a few cases have been described. This condition is characterized by local bulging in the piriform recess or in a vallecula. The diagnosis, which is clinically difficult, is made by barium-swallow examination of the pharynx. Surgical repair is indicated when symptoms are present. We report 3 new cases of LPD, and we discuss the etiology and clinical features of this entity. We also present a short review of the literature.
