A Comparative Analysis of Serum IgG4 Levels in Patients With IgG4-Related Disease and Other Disorders.

Elevated serum IgG4 levels are an important hallmark for diagnosing IgG4-related disease (IgG4-RD) but can also be found and reported in other diseases. The present study intended to compare the serum IgG4 levels in both IgG4-RD and non-IgG4-RD and determine the serum IgG4 levels in patients with IgG4-RD before and after glucocorticoid therapy.

The effect of lidocaine jelly on a taper-shaped cuff of an endotracheal tube on the postoperative sore throat: a prospective randomized study: A CONSORT compliant article.

Postoperative sore throat (POST) following general anesthesia with endotracheal intubation is a common complication. We hypothesized that lidocaine jelly applied to the tapered cuff of the endotracheal tube (ETT) might decrease the incidence of POST most commonly arising from endotracheal intubation.

Prognostic value of maximum standard uptake value, metabolic tumor volume, and total lesion glycolysis of positron emission tomography/computed tomography in patients with nasopharyngeal carcinoma: A systematic review and meta-analysis.

The maximal standard uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) of positron emission tomography/computed tomography (PET/CT) in patients with nasopharyngeal carcinoma (NPC) perform as new prognostic factors, but the outcomes of the published articles were inconclusive. In this meta-analysis, we evaluated the prognostic value of SUVmax, MTV, and TLG of PET/CT in patients with NPC.

Risk factors for postoperative throat pain after general anaesthesia with endotracheal intubation at the University of Gondar Teaching Hospital, Northwest Ethiopia, 2014.

Postoperative sore throat is listed from the top as patients' most undesirable outcome in the postoperative period. It is believed to originate from mucosal dehydration or edema, tracheal ischemia secondary to the pressure of endotracheal tube cuffs, aggressive oropharyngeal suctioning, and mucosal erosion from friction between delicate tissues and the endotracheal tube. Even if the problem was indicated in many literatures, it has never been studied in our country. The study aimed to assess prevalence and factors associated with postoperative sore throat among patients who were operated under general anesthesia with endotracheal intubation.

Colony Stimulating Factor-1 Receptor Expressing Cells Infiltrating the Cornea Control Corneal Nerve Degeneration in Response to HSV-1 Infection.

Herpes simplex virus type-1 (HSV-1) is a leading cause of neurotrophic keratitis, characterized by decreased or absent corneal sensation due to damage to the sensory corneal innervation. We previously reported the elicited immune response to infection contributes to the mechanism of corneal nerve regression/damage during acute HSV-1 infection. Our aim is to further establish the involvement of infiltrated macrophages in the mechanism of nerve loss upon infection.

Use of Antibiotic-Impregnated Absorbable Beads and Tissue Coverage of Complex Wounds.

The treatment of complex wounds is commonplace for plastic surgeons. Standard management is debridement of infected and devitalized tissue and systemic antibiotic therapy. In cases where vital structures are exposed within the wound, coverage is obtained with the use of vascularized tissue using both muscle and fasciocutaneous flaps. The use of nondissolving polymethylmethacrylate and absorbable antibiotic-impregnated beads has been shown to deliver high concentrations of antibiotics with low systemic levels of the same antibiotic. We present a multicenter retrospective review of all cases that used absorbable antibiotic-impregnated beads for complex wound management from 2003 to 2013. A total of 104 cases were investigated, flap coverage was used in 97 cases (93.3%). Overall, 15 patients (14.4%) required reoperation with the highest groups involving orthopedic wounds and sternal wounds. The advantages of using absorbable antibiotic-impregnated beads in complex infected wounds have been demonstrated with minimal disadvantages. The utilization of these beads is expanding to a variety of complex infectious wounds requiring high concentrations of local antibiotics.

Are Multiple Tumors of the Parotid Gland Uncommon or Underestimated?

Parotid gland tumors are mostly solitary tumors of the salivary gland tissue. There is limited evidence about multifocal tumor growth of the parotid gland.

Fixed-functional appliance treatment combined with growth hormone therapy.

The purpose of this study was to illustrate the effects of growth hormone (GH) therapy and fixed functional appliance treatment in a 13-year-old Class II malocclusion patient without GH deficiency. GH has been shown to effectively increase endochondral growth and induce a more prognathic skeletal pattern. Although a major concern in Class II retrognathic patients is chin deficiency, long-term studies have shown that the mandibular growth enhancement effects of functional appliances are clinically insignificant. This case report demonstrates that the mandible grew significantly during fixed functional appliance treatment combined with GH therapy, with stable results during 2 years 11 months of retention. More studies are needed to evaluate GH therapy as a supplement in Class II treatment.

Combined orthodontic-orthopedic treatment of an adolescent Class II Division 2 patient with extreme deepbite using the Forsus Fatigue Resistant Device.

Class II Division 2 malocclusion is often characterized by severe, traumatic deepbite with lingually inclined and overerupted incisors. Combined orthodontic-orthopedic treatment of this malocclusion is a challenging issue for orthodontists. This case report describes the combined orthodontic-orthopedic treatment of an adolescent Class II Division 2 patient with an extreme deepbite and a retrognathic mandible using the Forsus Fatigue Resistant Device.

Genome-wide association study for mandibular prognathism using microsatellite and pooled DNA method.

The purpose of this study was to extend an association study from chromosome 1 to the whole genome (genome-wide association study) to find susceptibility loci of mandibular prognathism.

Three-dimensional evaluation of the airway spaces in patients with and without cleft lip and palate: A digital volume tomographic study.

Patients with cleft lip and palate (CLP) suffer from several esthetic and functional challenges. Comprehensive treatment of these patients involves orthognathic surgery that may lead to velopharyngeal insufficiency or reduction in lower airway. Several cases of airway insufficiency, velopharyngeal incompetence, snoring, hypopnea, and obstructive sleep apnea have been reported in subjects with CLP. The aim of this study was to compare the anteroposterior dimensions of the oropharyngeal airway at 5 levels, the height of the oropharyngeal column, and the volume of the oropharyngeal airway in subjects with and without CLP.

Assessment of upper airway size after orthopedic treatment for maxillary protrusion or mandibular retrusion.

The aim of this retrospective study was to find out whether different Class II treatments would affect the airway sizes of patients having maxillary protrusion or mandibular retrusion.

Root resorptions associated with canine retraction treatment.

The hypothesis of this study was that multiple factors are dominant in causing external apical root resorption (EARR). The objective of this investigation was to better understand the clinical factors that may lead to EARR.

Three-dimensional assessment of soft tissue changes associated with bone-anchored maxillary protraction protocols.

The aim of this study was to assess the 3-dimensional soft tissue changes in growing Class III patients with maxillary deficiency associated with 2 bone-anchored maxillary protraction protocols in relation to an untreated control group of Class III patients.

Bone-anchored maxillary protraction therapy in patients with unilateral complete cleft lip and palate: 3-dimensional assessment of maxillary effects.

The aim of this study was to 3-dimensionally assess the treatment outcomes of bone-anchored maxillary protraction (BAMP) in patients with unilateral cleft lip and palate.

Prevalence of extraction space reopening in different orthodontic treatment protocols.

In this study, we aimed to compare the amount and frequency of extraction space reopening after 2- and 4-premolar extraction treatments in Class II and 4-premolar extractions in Class I malocclusion patients.

Risk factors of periodontal disease in maintenance hemodialysis patients.

To explore the characteristics and relevant risk factors of periodontal disease (PD) among hemodialysis patients.Uremic patients on maintenance hemodialysis from November 2015 to March 2016 were retrospectively reviewed. Patients were divided into a PD group and a non-PD group. Demographic and laboratory data were collected and analyzed.In all, 136 uremic patients (79 males and 57 females, aged 50.8 ± 15.3 years) on maintenance hemodialysis were included in this study. The incidence of PD increased with age. Hemodialysis patients most likely developed PD if they were male, smokers, or diabetic (P = .009, <.001, and <.001, respectively). Patients brushing their teeth twice daily had significantly less chance of developing PD as compared with those only brushing once daily (P < .001). Hemodialysis patients in the PD group had significantly higher levels of total cholesterol, high-sensitivity C-reactive protein, fasting blood glucose, and peripheral white blood cell counts, compared with the non-PD group (all P < .001). Logistic regression analysis revealed that diabetes, total cholesterol, high-sensitivity C-reactive protein, and peripheral white blood cell count were independent risk factors for developing PD, whereas teeth brushing twice daily and serum calcium were favorable factors for maintenance hemodialysis patients against PD.Identification of risk factors provides a theoretical basis for prevention and improvement of PD among maintenance hemodialysis patients.

Oral and maxillofacial non-Hodgkin lymphomas: Case report with review of literature.

Lymphomas take up about 14% of all head-neck malignancies, out of which 97% are non-Hodgkin lymphomas (NHL). The clinical courses, treatment responses, and prognoses of NHLs vary with different subtypes and anatomic sites. In the Chinese population (including the Taiwanese), head-neck NHLs are often seen with the tonsils, nasal cavity, nasal sinus, and the nasopharynx. However, oral NHLs are relatively rare. Delay of diagnosis is also often seen in clinical practice. Thus, we present 4 cases with delayed diagnosis of oral maxillofacial NHLs and discuss their clinical manifestations so as to draw a clue that can remind the doctors to take biopsies in time.

The BeSMART (Best Supportive Management for Adults Referred with Tonsillopharyngitis) multicentre observational study.

Introduction Tonsillopharyngitis is the most common ear, nose and throat emergency admission, with 80,000 episodes recorded in England in 2015-2016. Despite this, there is a paucity of evidence addressing the supportive management of tonsillopharyngitis in inpatients. The aim of this retrospective multicentre observational study was to consider the Best Supportive Management for Adults Referred with Tonsillopharyngitis (BeSMART) in the inpatient setting, and to establish any associations between practice and outcomes. Methods Seven hospitals in North West England and North East Scotland participated in the study. Overall, 236 adult patients admitted with tonsillopharyngitis were included. The main outcome measures were interval to return to soft diet, length of stay (LOS), pain scores and readmissions. Results Women were more likely to seek professional help before presenting to secondary care (p=0.04). Patients admitted at the weekend were more likely to have a shorter LOS (p=0.03). There was no relationship between day of admission and seniority or specialty of the doctor initially seen. Prescription of corticosteroid, analgesia and a higher initial intravenous fluid infusion rate were not related to a shorter LOS. Conclusions This study is the first to yield valuable insights into the inpatient management of tonsillopharyngitis. This work represents part of an ongoing project to establish the evidence for common medical interventions for sore throat. Patient and professional surveys as well as a prospective interventional study are planned for the future.

Preventive effects of the novel antimicrobial peptide Nal-P-113 in a rat Periodontitis model by limiting the growth of Porphyromonas gingivalis and modulating IL-1β and TNF-α production.

P-113 (AKRHHGYKRKFH-NH2) is a 12-amino-acid histidine-rich peptide derived from histatin 5 that is highly degradable in high salt concentrations and biological fluids such as serum, plasma and saliva. Nal-P-113, a novel antimicrobial peptide whose histidine residues are replaced by the bulky amino acids β-naphthylalanine, causes the antimicrobial peptide to retain its bactericidal activity even in physiological environments. This study evaluated the effect of the novel antimicrobial peptide Nal-P-113 in a rat periodontitis model and the mechanisms of action of Nal-P-113 for suppressing periodontitis.

American Society of Maxillofacial Surgeons 2006 to 2016: Another Decade of Excellence in Education and Research.

Over the past 10 years, the American Society of Maxillofacial Surgeons (ASMS) has continued to advance to meet its mission of being the premier organization to represent maxillofacial and pediatric plastic surgery in the United States. These advances are focused on education of its members, to include the American Society of Maxillofacial Surgeons basic course, the preconference symposium, the annual meeting, two basic maxillofacial courses per year, advanced maxillofacial courses, a boot camp for craniofacial fellows, a cleft course, quarterly webinars, sponsored fellowships, a visiting professorship, and the ASMS journal. In addition, the ASMS has continued to advance as the premier national organization representing maxillofacial and pediatric plastic surgery in the United States, thereby positioning the organization as a primary advocate for these surgical specialties. Outreach of the ASMS has grown over the past decade and now includes representatives to the American Society of Plastic Surgeons/Plastic Surgery Foundation, the American Board of Plastic Surgeons, the American Medical Association, and most recently a seat as a governor with the American College of Surgeons. The ASMS has also initiated an annual Summer Leadership Seminar to explore topics of relevance in a changing health care environment. The present report outlines the major initiatives of the ASMS over the past 10 years.

Cortical blindness and not optic neuritis as a cause of vision loss in a Sjögren's syndrome (SS) patient with the neuromyelitis optica spectrum disorder (NMOSD): Challenges of ascribing demyelinating syndromes to SS: a case report.

The conception that multiple sclerosis may be challenging to distinguish from demyelinating manifestations of Sjögren's syndrome (SS) was introduced more than 30 years ago. However, it is now recognized that the neuromyelitis optica spectrum disorder (NMOSD) may occur more frequently in SS as opposed to multiple sclerosis. Characteristic NMOSD features can include severe attacks of optic neuritis, myelitis which is frequently longitudinally-extensive (spanning at least three vertebral segments on magnetic resonance imaging [MRI]), and an association with anti-aquaporin-4 antibodies. In addition, whereas NMOSD was initially thought to spare the brain, it is now recognized that brain lesions occur in a majority of NMOSD patients. Therefore, it is important for the multi-disciplinary team of physicians who care for SS patients to understand this widening spectrum of NMOSD as encompassing brain lesions. In this case-report we describe clinical features, radiographic findings, and treatment of a SS NMOSD patient presenting with severely decreased visual acuity, visual hallucinations, and encephalopathy.

Ki-67 protein predicts survival in oral squamous carcinoma cells: an immunohistochemical study.

The aim of this study was to identify the expression of Ki-67 and MCM3 in oral squamous cell carcinoma (OSCC) as well as to address the correlation with patient survival and clinical features. Samples were collected from 51 patients with OSCC who presented for follow-up. Immunohistochemical expression of Ki-67 and MCM3 in all groups was performed. The scoring system was previous published by Tsurutani in 2005. We used Kappa index to evaluate observers agreement degree. The associations between protein expression and clinical variables were examined for statistical significance using the chi-squared test. The overall survival rates were estimated by the Kaplan-Meier method and the relationship between protein expression and survival was compared using the log-rank test (p < 0.05). The overall survival time for a patient with positive immunostaining for Ki-67 is shorter than for a patient with negative immunostaining, (log-rank test, p = 0.00882). Patients with tumor size T3 and T4 showed a statistically significant relationship with Ki-67 immunoexpression (log-rank test, p = 0.0174). The relationship between Ki-67 expression and the relation between age, gender, smoking, tumor site, lymph node metastasis and disease stage was not significant. The examiners agreement degree by Kappa presented p value < 0.05. There was not a significant correlation when we evaluated MCM3 expression regarding clinical characteristics and survival rate. From these results, the present study suggests that positive Ki-67 expression found in OSCC patients may contribute to predict the survival in OSCC samples, as well as the relation between the protein and the tumor size.

Different engagement of TLR2 and TLR4 in Porphyromonas gingivalis vs. ligature-induced periodontal bone loss.

This study was conducted to investigate the roles of different Toll-like receptor (TLR) signaling in Porphyromonas gingivalis (P. gingivalis)-induced and ligature-induced experimental periodontal bone resorption in mice. Wild-type (WT), TLR2 knockout (KO), TLR4KO, and TLR2&4 KO mice with C57/BL6 background were divided into three groups: control, P. gingivalis infection, and ligation. Live P. gingivalis or silk ligatures were placed in the sulcus around maxillary second molars over a 2-week period. Images were captured by digital stereomicroscopy, and the bone resorption area was measured with ImageJ software. The protein expression level of gingival RANKL was measured by ELISA. The gingival mRNA levels of RANKL, IL-1β, TNF-α, and IL-10 were detected by RT-qPCR. The results showed that P. gingivalis induced significant periodontal bone resorption in WT mice and TLR2 KO mice but not in TLR4 KO mice or TLR2&4 KO mice. For all four types of mice, ligation induced significant bone loss compared with that in control groups, and this bone loss was significantly higher than that in the P. gingivalis infection group. RANKL protein expression was significantly increased in the ligation group compared with that in the control group for all four types of mice, and in the P. gingivalis infection group of WT, TLR2 KO, and TLR4 KO mice. Expression patterns of RANKL, IL-1β, TNF-α, and IL-10 mRNA were different in the P. gingivalis infection group and the ligation group in different types of mice. In summary, P. gingivalis-induced periodontal bone resorption is TLR4-dependent, whereas ligation-induced periodontal bone resorption is neither TLR2- nor TLR4-dependent.

Open versus closed surgical exposure of canine teeth that are displaced in the roof of the mouth.

Palatally displaced canines or PDCs are upper permanent canines, commonly known as 'eye' teeth, that are displaced in the roof of the mouth. This can leave unsightly gaps, cause damage to the surrounding roots (which can be so severe that neighbouring teeth are lost or have to be removed) and, occasionally, result in the development of cysts. PDCs are a frequent dental anomaly, present in 2% to 3% of young people.Management of this problem is both time consuming and expensive. It involves surgical exposure (uncovering) followed by fixed braces for two to three years to bring the canine into alignment within the dental arch. Two techniques for exposing palatal canines are routinely used in the UK: the closed technique and the open technique. The closed technique involves uncovering the canine, attaching an eyelet and gold chain and then suturing the palatal mucosa back over the tooth. The tooth is then moved into position covered by the palatal mucosa. The open technique involves uncovering the canine tooth and removing the overlying palatal tissue to leave it uncovered. The orthodontist can then see the crown of the canine to align it.

Dental, dermatological and radiographic findings in a case of Gorlin-Goltz Syndrome: report and review.

Gorlin-Goltz syndrome (GGS) is a rare autosomal dominant disorder. The disease shows multiple organ involvement with variable clinical presentation. Thus a multidisciplinary approach is required for its prompt clinical diagnosis and management of this condition. This paper highlights a case of GGS presenting in a young male patient with cranial, facial, dermatological, dental and skeletal involvement. The diagnosis of the syndrome was based on its clinical presentation, radiological features and histopathological findings. A review of the diagnostic criteria is also presented.

Parotid metastasis from carcinoma of the breast: report of a case and review of the literature.

Parotid metastasis from carcinoma of the breast is very rare, only a few cases have been reported in the literature. We here report the case of a 43-year old patient treated for right breast cancer in whom left parotid metastasis (confirmed histologically) occurred two years after the end of the treatment.

Aggressive fibromatosis of the oral cavity in a 5 year old boy: a rare case report.

Fibrous tissue proliferations express a wide spectrum of histologic and morphologic variation in both infants and adults. This ranges from hypertrophic scar formation at one end to malignant fibrosarcoma at the other end of the spectrum. Aggressive fibromatosis is an intermediate tumor which is in proximity to fibrosarcomas. These are locally invasive and often recur after excision, but do not metastasize. Histologically, they are characterized by proliferating fibroblasts with little mitotic activity. Aggressive fibromatosis in the head and neck region is not common, and very sporadically occurs in the oral cavity or jaw bones. Here we report a rare case of aggressive fibromatosis occurring in a 5 year old boy.

Age threshold for moderate and severe periodontitis among Korean adults without diabetes mellitus, hypertension, metabolic syndrome, and/or obesity.

The purpose of this study is to determine an appropriate age threshold at which to recommend the evaluation of moderate and severe periodontitis among Korean adults.This study involved a cross-sectional analysis using data from the Korean National Health and Nutrition Examination Survey from 2012 to 2014. Incidence rates of periodontitis with the 95% confidence interval (CI) were evaluated. The predictive accuracy of age for periodontitis was determined by calculating the area under curve (AUC) on the basis of the receiver operating characteristic (ROC) curve.The cutoff value of age was 43 years in men having periodontitis with an AUC of 0.70 with 95% CI of 0.69 to 0.72. The AUC was 0.72 (95% CI: 0.70-0.73), and the cutoff value of age (49 years) was identified for the moderate periodontitis in women. The cutoff values for age with AUCs and 95% CI for individuals with periodontitis were 46 years (0.72 [0.71-0.73]), 43 years (0.73 [0.72, 0.74]), 45 years (0.71 [0.70,0.72]), 43 years (0.73 [0.72, 0.74]), and 45 years (0.74 [0.72, 0.75]) for no obesity, no abdominal obesity, no diabetes mellitus, no hypertension, and no metabolic syndrome groups, respectively.This study proposed the guideline for the appropriate age threshold at which to recommend the evaluation of moderate and severe periodontitis for the general population and additionally added the guideline for the individuals without systemic disease including diabetes mellitus, hypertension, metabolic syndrome, and obesity. This study suggests that the participants with certain age may be recommended for the regular periodontal evaluation.

Human papillomavirus in oropharyngeal cancer in Canada: analysis of 5 comprehensive cancer centres using multiple imputation.

The incidence of oropharyngeal cancer has risen over the past 2 decades. This rise has been attributed to human papillomavirus (HPV), but information on temporal trends in incidence of HPV-associated cancers across Canada is limited.
