Abstract
Ameloblastic fibro-odontoma is a rare, benign, and slowly growing neoplasm of the jaw composed of proliferating odontogenic epithelium in ectomesenchymal tissue along with dental hard tissue formation. Herein, we describe a case of an ameloblastic fibro-odontoma in 12-year-old female with paresthesia of the chin and lower lip. Panoramic radiography showed a radio-opacity in the right posterior mandible near the mandibular canal and associated with the right mandibular third molar. Histologically, the lesion contained epithelial and mesenchymal odontogenic components in close proximity to odontoma-like elements. Enucleation and curettage of the affected site in the mandible resulted in resolution of the paresthesia postoperatively.

Abstract
PURPOSE In advanced stage head and neck squamous cell cancers (HNSCC), approximately half of the patients with lymph node metastases (LNM) are not cured. Given the heterogeneous outcomes in these patients, we profiled the expression patterns of LNMs to identify the biological factors associated with patient outcomes.Experimental Design: We performed mRNAseq and miRNAseq on 72 LNMs and 29 matched primary tumors from 34 patients with HNSCC. Clustering identified molecular subtypes in LNMs and in primary tumors. Prediction Analysis of Microarrays algorithm identified a 73-gene classifier that distinguished LNM subtypes. Gene-set enrichment analysis identified pathways upregulated in LNM subtypes. RESULTS Integrative clustering identified three distinct LNM subtypes: (i) an immune subtype (Group 1), (ii) an invasive subtype (Group 2), and (iii) a metabolic/proliferative subtype (Group 3). Group 2 subtype was associated with significantly worse locoregional control and survival. LNM-specific subtypes were not observed in matched primary tumor specimens. In HNSCCs, breast cancers, and melanomas, a 73-gene classifier identified similar Group 2 LNM subtypes that were associated with worse disease control and survival only when applied to lymph node sites, but not when applied to other primary tumors or metastatic sites. Similarly, previously proposed prognostic classifiers better distinguished patients with worse outcomes when applied to the transcriptional profiles of LNMs, but not the profiles of primary tumors. CONCLUSIONS The transcriptional profiles of LNMs better predict outcomes than transcriptional profiles of primary tumors. The LNMs display site-specific subtypes associated with worse disease control and survival across multiple cancer types.

Abstract
Oral tongue squamous cell carcinoma (TSCC) is a complex disease with extensive genetic and epigenetic defects, including microRNA deregulation. The aims of the present study were to test the feasibility of performing the microRNA profiling analysis on archived TSCC specimens and to assess the potential diagnostic utility of the identified microRNA biomarkers for the detection of TSCC. TaqMan array-based microRNA profiling analysis was performed on 10 archived TSCC samples and their matching normal tissues. A panel of 12 differentially expressed microRNAs was identified. Eight of these differentially expressed microRNAs were validated in an independent sample set. A random forest (RF) classification model was built with miR-486-3p, miR-139-5p, and miR-21, and it was able to detect TSCC with a sensitivity of 100% and a specificity of 86.7% (overall error rate = 6.7%). As such, this study demonstrated the utility of the archived clinical specimens for microRNA biomarker discovery. The feasibility of using microRNA biomarkers (miR-486-3p, miR-139-5p, and miR-21) for the detection of TSCC was confirmed.

Abstract
BACKGROUND The genes for PFN1 and TMSB4 are both highly expressed in oral tissue and both encode actin monomer binding proteins thought to play a role in cell motility and possibly other crucial parts of tumor progression. METHODS Oral brush cytology of epithelium from oral squamous cell carcinoma (OSCC) was used to measure PFN1 and TMSB4 mRNA in OSCC, while immunohistochemical analysis of tissue was used to check protein levels. RESULTS High but variable expression of mRNAs encoding these two proteins was observed suggesting they may contribute to tumor characteristics in a subset of OSCCs. Both proteins were highly expressed in normal appearing basal epithelium, in the cytoplasm, and perinuclear area, while expression was minimal in upper epithelial layers. In OSCCs, expression of these proteins varied. In tumors classified as later stage, based on size and/or lymph node involvement, PFN1 levels were lower in tumor epithelium. A control gene, KRT13, showed expression in normal differentiated basal and suprabasal oral mucosa epithelial cells and as reported was lost in OSCC cells. CONCLUSION Loss of PFN1 in tumor cells has been associated with lymph node invasion and metastasis in other tumor types, strengthening the argument that the protein has the potential to be a tumor suppressor in late-stage OSCC.

Abstract
Background Oral tongue squamous cell carcinoma (OTSCC) is one of the most aggressive forms of head and neck/oral cancer (HNOC), and is a complex disease with extensive genetic and epigenetic defects, including microRNA deregulation. Identifying the deregulation of microRNA-mRNA regulatory modules (MRMs) is crucial for understanding the role of microRNA in OTSCC. Methods A comprehensive bioinformatics analysis was performed to identify MRMs in HNOC by examining the correlation among differentially expressed microRNA and mRNA profiling datasets and integrating with 12 different sequence-based microRNA target prediction algorithms. Confirmation experiments were performed to further assess the correlation among MRMs using OTSCC patient samples and HNOC cell lines. Functional analyses were performed to validate one of the identified MRMs: miR-21-15-Hydroxyprostaglandin Dehydrogenase (HPGD) regulatory module. Results Our bioinformatics analysis revealed 53 MRMs that are deregulated in HNOC. Four high confidence MRMs were further defined by confirmation experiments using OTSCC patient samples and HNOC cell lines, including miR-21-HPGD regulatory module. HPGD is a known anti-tumorigenic effecter, and it regulates the tumorigenic actions of Prostaglandin E2 (PGE2) by converts PGE2 to its biologically inactive metabolite. Ectopic transfection of miR-21 reduced the expression of HPGD in OTSCC cell lines, and the direct targeting of the miR-21 to the HPGD mRNA was confirmed using a luciferase reporter gene assay. The PGE2-mediated upregulation of miR-21 was also confirmed which suggested the existence of a positive feed-forward loop that involves miR-21, HPGD and PGE2 in OTSCC cells that contribute to tumorigenesis. Conclusions We identified a number of high-confidence MRMs in OTSCC, including miR-21-HPGD regulatory module, which may play an important role in the miR-21-HPGD-PGE2 feed-forward loop that contributes to tumorigenesis.

Abstract
OBJECTIVE We previously performed a meta-analysis of microRNA profiling studies on head and neck/oral cancer (HNOC), and identified 11 consistently dysregulated microRNAs in HNOC. Here, we evaluate the diagnostic values of these microRNAs in oral tongue squamous cell carcinoma (OTSCC) using oral cytology samples. MATERIALS AND METHODS The levels of 11 microRNAs were assessed in 39 oral cytology samples (19 OTSCC and 20 normal subjects), and 10 paired OTSCC and adjacent normal tissues. The predictive power of these microRNAs was analyzed by receiver operating characteristic curve (ROC) and random forest (RF) model. A classification and regression trees (CART) model was generated using miR-21 and miR-375, and further validated using both independent oral cytology validation sample set (14 OTSCC and 11 normal subjects) and tissue validation sample set (12 paired OTSCC and adjacent normal tissues). RESULTS Differential expression of miR-21, miR-100, miR-125b and miR-375 was validated in oral cytology training sample set. Based on the RF model, the combination of miR-21 and miR-375 was selected which provide best prediction of OTSCC. A CART model was constructed using miR-21 and miR-375, and was tested in both oral cytology and tissue validation sample sets. A sensitivity of 100% and specificity of 64% was achieved in distinguishing OTSCC from normal in the oral cytology validation set, and a sensitivity of 83% and specificity of 83% was achieved in the tissue validation set. CONCLUSION The utility of microRNA from oral cytology samples as biomarkers for OTSCC detection is successfully demonstrated in this study.

Abstract
PURPOSE The purpose of this report is to describe a rare case of delayed metachronous isolated metastases of renal cell carcinoma (RCC) to the parotid gland and the cerebellum. The metastases occurred more than a decade after treatment of the primary tumor without any other systemic involvement. In addition, the potential differential diagnosis of the parotid mass based on presentation and imaging is discussed. MATERIALS AND METHODS An 83-year-old man presented for evaluation and treatment of a rapidly growing mass at the right parotid region. He had a history of RCC resection 10 years before this presentation and had no evidence of persistent disease at the primary site. The diagnosis of metastatic RCC was made after fine-needle aspiration biopsy examination of the mass. The patient underwent superficial parotidectomy for resection of the tumor. Approximately 1.5 years later, he complained of loss of balance. Further investigation disclosed a cerebellar mass that at biopsy examination was found to represent RCC. He underwent stereotactic ablation of the mass. He currently remains free of disease at the primary site and the parotid and without further known brain metastases. RESULTS This report presents the 29th case of a solitary parotid mass consistent with metastatic RCC 10 years after successful treatment of the primary RCC. Approximately 1.5 years later, the patient presented with new-onset loss of balance. Further investigation disclosed a mass to the cerebellum consistent with metastatic RCC. This case is unique because the brain involvement occurred extremely late, 11.5 years after successful treatment of primary RCC and 1.5 years after resection of a metastatic RCC to the parotid, and without any evidence of other metastases. CONCLUSIONS Late distant metastases of RCC are not uncommon and patients require life surveillance follow-up, but such late presentation of metachronous metastases without systemic disease progression is unique. The patterns of metastases of RCC are not clearly defined and this diagnosis should be considered, especially in patients with relevant history.

Abstract
Acute pancreatitis (AP), although most often a mild and self-limiting inflammatory disease, worsens to a characteristically necrotic severe acute pancreatitis (SAP) in about 20% of cases. Obesity, affecting more than one-third of American adults, is a risk factor for the development of SAP, but the exact mechanism of this association has not been identified. Coincidental with chronic low-grade inflammation, activation of the nucleotide-binding domain, leucine-rich containing family, pyrin-domain containing 3 (NLRP3) inflammasome increases with obesity. Lean mice genetically deficient in specific components of the NLRP3 inflammasome are protected from experimentally induced AP, indicating a direct involvement of this pathway in AP pathophysiology. We hypothesized that inhibition of the NLRP3 inflammasome with the sulfonylurea drug glyburide would reduce disease severity in obese mice with cerulein-induced SAP. Treatment with glyburide led to significantly reduced relative pancreatic mass and water content and less pancreatic damage and cell death in genetically obese ob/ob mice with SAP compared with vehicle-treated obese SAP mice. Glyburide administration in ob/ob mice with cerulein-induced SAP also resulted in significantly reduced serum levels of interleukin 6, lipase, and amylase and led to lower production of lipopolysaccharide-stimulated interleukin 1β release in cultured peritoneal cells, compared with vehicle-treated ob/ob mice with SAP. Together, these data indicate involvement of the NLRP3 inflammasome in obesity-associated SAP and expose the possible utility of its inhibition in prevention or treatment of SAP in obese individuals.

Abstract
CONTEXT Some dental abnormalities have environmental causes. Other odontogenic alterations are idiopathic and may have hereditary etiologies. Investigations of these conditions are ongoing. OBJECTIVE To provide a discussion of developmental odontogenic abnormalities and benign odontogenic overgrowths and neoplasms for which genetic alterations have been well demonstrated and well documented. DATA SOURCES Relevant peer-reviewed literature. CONCLUSIONS The understanding of benign odontogenic lesions at a molecular level is rather well developed for some lesions and at the initial stages for many others. Further characterization of the molecular underpinnings of these and other odontogenic lesions would result in an enhanced comprehension of odontogenesis and the pathogenesis of a variety of odontogenic aberrations. These advancements may lead to better prevention and treatment paradigms and improved patient outcomes.

Abstract
Background Increased cellular iron exposure is associated with colorectal cancer (CRC) risk. Hepcidin, a liver peptide hormone, acts as the primary regulator of systemic iron status by blocking iron release from enterocytes into plasma. Concentrations are decreased during low iron status and increased during inflammation. The role of hepcidin and the factors influencing its regulation in CRC remains largely unknown. This study explored systemic and tumor level iron regulation in men with CRC. Methods The participants were 20 CRC cases and 20 healthy control subjects. Colonic tissue (adenocarcinoma [cases] healthy mucosa [controls]) was subjected to quantitative PCR (hepcidin, iron transporters and IL-6) and Perls’ iron staining. Serum was analyzed using ELISA for hepcidin, iron status (sTfR) and inflammatory markers (CRP, IL-6, TNF-α). Anthropometrics, dietary iron intake and medical history were obtained. Results Cases and controls were similar in demographics, medication use and dietary iron intake. Systemically, cases compared to controls had lower iron status (sTfR: 21.6 vs 11.8 nmol/L, p < 0.05) and higher marker of inflammation (CRP: 8.3 vs 3.4 μg/mL, p < 0.05). Serum hepcidin was mildly decreased in cases compared to controls; however, it was within the normal range for both groups. Within colonic tissue, 30% of cases (6/20) presented iron accumulation compared to 5% of controls (1/20) (χ2 = 5.0; p < 0.05) and higher marker of inflammation (IL-6: 9.4-fold higher compared to controls, p < 0.05). Presence of adenocarcinoma iron accumulation was associated with higher serum hepcidin (iron accumulation group 80.8 vs iron absence group 22.0 ng/mL, p < 0.05). Conclusions While CRC subjects had serum hepcidin concentrations in the normal range, it was higher given their degree of iron restriction. Inappropriately elevated serum hepcidin may reduce duodenal iron absorption and further increase colonic adenocarcinoma iron exposure. Future clinical studies need to assess the appropriateness of dietary iron intake or iron supplementation in patients with CRC.

Abstract
Objectives Head and neck/oral cancer, predominantly head and neck squamous cell
carcinoma (HNSCC), is the sixth most common cancer in the world. While
substantial advances have been made to define the genomic alterations
associated with head and neck/oral cancer, most studies are focused on
protein coding genes. The aim of this article is to review the current
literature on identified genomic aberrations of non-coding genes (e.g.,
microRNA) in head and neck/oral cancer (HNOC), and their contribution to the
initiation and progression of HNOC. Material and Methods A comprehensive review of the available literature relevant to microRNA
deregulation in HNSCC/HNOC, was undertaken using PubMed, Medline, Scholar
Google and Scopus. Keywords for the search were: microRNA and oral cancer,
microRNA and squamous cell carcinoma, microRNA deregulation and oral cancer,
microRNA and carcinogenesis in the head and neck/oral cavity. Only full
length articles in the English language were included. Results We recently identified a panel of microRNA deregulations that were
consistently observed in HNSCC [Chen et al., Oral Oncol. 2012;48(8):686-91],
including 7 consistently up-regulated microRNAs (miR-21, miR-7, miR-155,
miR-130b, miR-223, miR-34b), and 4 consistently down-regulated microRNAs
(miR-100, miR-99a, miR-125b, miR-375). In this review, we will first provide
an overview on microRNA and HNSCC. We will then provide a comprehensive
review on the roles of microRNA deregulations in HNSCC. The functional
significance of the identified HNSCC-associated microRNAs and a number of
other relevant microRNAs (e.g., miR-138, miR-98, miR-137, miR-193a and
miR-218) will be discussed in detail. Conclusions Based on current literature, microRNA deregulation plays a major role in head
and neck/oral cancer.

Abstract
Obesity and type 2 diabetes are associated with increased production of Galectin-3 (Gal-3), a protein that modulates inflammation and clearance of glucose adducts. We used Lean and Diet-induced Obese (DIO) WT and Gal-3 KO mice to investigate the role of Gal-3 in modulation of adiposity, glucose metabolism and inflammation. Deficiency of Gal-3 lead to age-dependent development of excess adiposity and systemic inflammation, as indicated by elevated production of acute-phase proteins, number of circulating pro-inflammatory Ly6Chigh monocytes and development of neutrophilia, microcytic anemia and thrombocytosis in 20-week-old Lean and DIO male Gal-3 KO mice. This was associated with impaired fasting glucose, heightened response to a glucose tolerance test and reduced adipose tissue expression of adiponectin, Gal-12, ATGL and PPARγ, in the presence of maintained insulin sensitivity and hepatic expression of gluconeogenic enzymes in 20-week-old Gal-3 KO mice compared to their diet-matched WT controls. Expression of PGC-1α and FGF-21 in the liver of Lean Gal-3 KO mice was comparable to that observed in DIO animals. Impaired fasting glucose and altered responsiveness to a glucose load preceded development of excess adiposity and systemic inflammation, as demonstrated in 12-week-old Gal-3 KO mice. Finally, a role for the microflora in mediating the fasting hyperglycemia, but not the excessive response to a glucose load, of 12-week-old Gal-3 KO mice was demonstrated by administration of antibiotics. In conclusion, Gal-3 is an important modulator of glucose metabolism, adiposity and inflammation.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is an aggressive life-threatening disease associated with high mortality rates. While efforts have been made to explore the molecular mechanisms that contribute to the initiation and progression of HNSCC, most studies focus on protein-coding genes. Understanding of the genomic aberrations associated with noncoding genes (such as microRNAs) and their effects on HNSCC is still relatively limited. Recent evidence suggests that deregulation of microRNA genes (such as downregulation of miR-138) plays an important role in HNSCC. While deregulation of miR-138 has been frequently observed in HNSCC and other cancer types, the precise roles of miR-138 in tumorigenesis remain elusive. Recent bioinformatics analyses and functional studies using in vitro and in vivo systems have identified a number of functional targets for miR-138. These include genes that participate in essential biological processes that are highly relevant to the initiation and progression of HNSCC, including cell migration, epithelial to mesenchymal transition, cell cycle progression, DNA damage response and repair, senescence, and differentiation. However, the biological systems, study design, and data interpretation from these studies are highly variable, which hinder our understanding of the role of miR-138 in tumorigenesis at molecular level. In this review, we will first introduce the significance of microRNA deregulation in HNSCC. We will then provide a comprehensive review and integrative analysis of the existing studies on miR-138, and aim to define its molecular mechanisms that contribute to the initiation and progression of HNSCC.

Abstract
Obesity increases severity of acute pancreatitis (AP) by unclear mechanisms. We investigated the effect of the PPAR-gamma agonist rosiglitazone (RGZ, 0.01% in the diet) on severity of AP induced by administration of IL-12+ IL-18 in male C57BL6 mice fed a low fat (LFD) or high fat diet (HFD), under the hypothesis that RGZ would reduce disease severity in HFD-fed obese animals. In both LFD and HFD mice without AP, RGZ significantly increased body weight and % fat mass, with significant upregulation of adiponectin and suppression of erythropoiesis. In HFD mice with AP, RGZ significantly increased survival and hastened recovery from pancreatic inflammation, as evaluated by significantly improved pancreatic histology, reduced saponification of visceral adipose tissue and less severe suppression of erythropoiesis at Day 7 post-AP. This was associated with significantly lower circulating and pancreas-associated levels of IL-6, Galectin-3, osteopontin and TIMP-1 in HFD + RGZ mice, particularly at Day 7 post-AP. In LFD mice with AP, RGZ significantly worsened the degree of intrapancreatic acinar and fat necrosis as well as visceral fat saponification, without affecting other parameters of disease severity or inflammation. Induction of AP lead to major suppression of adiponectin levels at Day 7 in both HFD and HFD + RGZ mice. In conclusion, RGZ prevents development of severe AP in obese mice even though it significantly increases adiposity, indicating that obesity can be dissociated from AP severity by improving the metabolic and inflammatory milieu. However, RGZ worsens selective parameters of AP severity in LFD mice.

Abstract
Obesity increases severity of acute pancreatitis and risk of pancreatic cancer. Pancreatitis and obesity are associated with elevated IL-6, a cytokine involved in inflammation and tumorigenesis. We studied the role of IL-6 in the response of lean and obese mice to pancreatitis induced by IL-12 + IL-18. Lean and diet-induced obese (DIO) WT and IL-6 KO mice and ob/ob mice pretreated with anti-IL-6 antibodies were evaluated at Days 1, 7, and 15 after induction of pancreatitis. Prolonged elevation of IL-6 in serum and visceral adipose tissue was observed in DIO versus lean WT mice, whereas circulating sIL-6R declined in DIO but not lean mice with pancreatitis. The severe inflammation and lethality of DIO mice were also observed in IL-6 KO mice. However, the delayed resolution of neutrophil infiltration; sustained production of CXCL1, CXCL2, and CCL2; prolonged activation of STAT-3; and induction of MMP-7 in the pancreas, as well as heightened induction of serum amylase A of DIO mice, were blunted significantly in DIO IL-6 KO mice. In DIO mice, production of OPN and TIMP-1 was increased for a prolonged period, and this was mediated by IL-6 in the liver but not the pancreas. Results obtained in IL-6 KO mice were confirmed in ob/ob mice pretreated with anti-IL-6 antibodies. In conclusion, IL-6 does not contribute to the increased severity of pancreatitis of obese mice but participates in delayed recovery from acute inflammation and may favor development of a protumorigenic environment through prolonged activation of STAT-3, induction of MMP-7, and sustained production of chemokines.

Abstract
OBJECTIVES Leptin and adiponectin (APN) are adipokines produced by adipocytes that participate in the modulation of immune and inflammatory responses. In Crohn's disease (CD), fat wrapping surrounding the inflamed intestine produces high levels of leptin and APN. In inflammatory bowel disease (IBD), apoptosis resistance of lamina propria T lymphocytes (LPL-T) is one of the mechanisms that maintains chronic inflammation. We addressed the mechanism by which leptin and APN regulate inflammation and apoptosis in IBD. METHODS Immune cell infiltration, several factors expressed by adipose tissue (AT), and spontaneous release of cytokines by adipocytes were measured. The presence of APN and leptin in intestinal mucosa was detected and their effect on LPL-T apoptosis, signal transducer and activator of transcription 3 (STAT3), Suppressor of Cytokine Signaling 3 (SOCS3), Bcl-2 and Bcl-xL expression, and cytokine production was studied. In addition, the effects of globular and high-molecular-weight (HMW) APN on LPL-T cytokine production and apoptosis were studied. RESULTS Higher levels of several chemokines, cytokines, and growth factors were present in AT near active than near inactive disease. A significantly higher amount of inflammatory infiltrate was present in AT near active CD than near ulcerative colitis, controls, and near the inactive area of CD. There were no changes in the ratios of APN molecular weight in control and IBD adipocyte products. Leptin and APN inhibited anti-CD3-stimulated-LPL-T apoptosis and potentiated STAT3 phosphorylation, Bcl-2, and Bcl-xL expression in IBD and control mucosa. However, SOCS3 expression was suppressed only in IBD. Both globular and HMW APN have similar effects on LPL-T cytokine production and apoptosis. Leptin and APN enhanced interleukin (IL)-10 production by anti-CD3-stimulated LPL-T in IBD only. APN, but not leptin, increased anti-CD3-induced IL-6 levels in LPL-T only in IBD patients. IL-10 exerts its anti-inflammatory activity in the presence of SOCS3 suppression by leptin or APN. CONCLUSION Leptin and APN maintain the inhibition of anti-CD3-stimulated LPL-T apoptosis by enhancing Bcl-2 and Bcl-xL overexpression and promoting STAT3 phosphorylation while suppressing SOCS3.

Abstract
Obesity is associated with increased severity of acute pancreatitis (AP). We recently developed a model of AP induced by administration of interleukin (IL)-12+IL-18, two cytokines that are elevated in patients with AP. In this model, severe AP develops in obese leptin-deficient ob/ob mice compared to lean littermates. In the present report, we evaluated the pancreatic response of diet-induced obesity (DIO) mice to IL-12+IL-18. Body weight loss and adipose tissue necrosis were more severe and prolonged in cytokine-injected DIO compared to lean mice. Edematous AP developed in lean mice, whereas DIO mice developed necrotizing AP. Obese DIO mice developed more severe hypocalcemia, increased liver damage and a heightened acute-phase response compared to lean mice, although leukopenia and thrombocytopenia were of comparable severity in lean and DIO mice. Serum levels of IL-6, IL-10, and IL-22 were significantly higher in DIO compared to lean mice, whereas interferon-gamma and tumor necrosis factor-alpha did not differ between the two groups. In conclusion, obesity induced by high-fat diet is associated with increased disease severity and duration in the model of AP induced by administration of IL-12+IL-18.

Abstract
BACKGROUND Discordant results of cervical biopsy histology after a cytologic diagnosis of high-grade squamous intraepithelial lesion (HSIL) are often attributed to sampling variation. The purpose of the current study was to determine whether deeper levels and ancillary staining (p16(Ink4a) and ProExC) reduce the discordant rate. METHODS A total of 246 cases of HSIL were retrieved from the computerized database from 2005 and 2006. Of these cases, 151 were followed by cervical biopsy. There was cytologic-histologic correlation in 87 cases, as defined by the presence of high-grade (2 or 3) cervical intraepithelial neoplasia (HGCIN). For each discordant biopsy (n = 64), 2 deeper levels for hematoxylin and eosin (H&E) were taken at 30-micro and 90-micro depths, and 4 sections for p16(Ink4a) and ProExC staining were taken at a 60-micro depth. All cytologic and histologic material from these 64 cases was reviewed by 3 cytopathologists. In 2 cases, the original HSIL diagnoses were downgraded and the cases censored from the study. RESULTS Fifty-seven of the 62 discordant cases had sufficient tissue for deeper levels and ancillary staining. Two of 57 cases were reclassified to HGCIN. In both of these cases, reclassification was suggested by results of immunostains; however, the H&E sections were necessary for definitive interpretation of the immunostain results. CONCLUSIONS In the current study, deeper levels and ancillary staining with p16(Ink4a) and ProExC did not significantly reduce the discordance rate. Although there are many known causes of sampling variation, including factors related to colposcopic technique, regression of infection, and insufficient histologic sectioning, sampling variation remains a valid justification of noncorrelation in women with HSIL followed up by cervical biopsy alone.

Abstract
The goal of this study was to investigate the role of the adipokine adiponectin (APN) in development of spontaneous colitis in IL-10 knockout (KO) mice. To this aim, we generated double IL-10 APN KO mice and compared their disease development to that of single IL-10 KO mice. Both IL-10 KO and double IL-10 APN KO mice spontaneously developed colitis of comparable severity. No significant differences in inflammatory infiltrate or crypt elongation were observed in colonic tissue obtained from IL-10 KO and double IL-10 APN KO mice at either 12 or 20 wk of age. A comparable increase in circulating levels of serum amyloid A and IFN-gamma was observed in IL-10 KO and double IL-10 APN KO mice as disease progressed. In vitro stimulation of lymphocytes from mesenteric lymph nodes with anti-CD3 and anti-CD28 induced a significantly higher production of IL-17 and TNF-alpha in IL-10 KO and double IL-10 APN KO mice compared with their healthy littermates. No significant differences in cytokine production from lymphocytes or colonic mRNA expression of cytokines were observed between IL-10 KO and double IL-10 APN KO mice. Both IL-10 KO and double IL-10 APN KO mice had a similar decrease in body weight and bone mass compared with their respective healthy littermates. Finally, APN deficiency did not lead to development of insulin resistance, either in APN KO or double IL-10 APN KO mice. In conclusion, lack of APN does not play a significant role in the pathogenesis of spontaneous colonic inflammation in the IL-10 KO model.

Abstract
Teratomas, most often diagnosed in younger patients, represent the most frequently identified subtype of pediatric germ cell tumors. It is very uncommon for teratomas to present in the head and neck region and demonstrate malignant transformation. We present a case of squamous cell carcinoma arising in an alpha-fetoprotein-producing cystic teratoma of the mandible in a 2-year-old female that is, to the best of our knowledge, the first such published report. The patient was treated with surgical excision along with chemotherapy and has remained disease-free 2 years after the conclusion of therapy.

Abstract
Leptin-deficient ob/ob mice are resistant to dextran sulfate sodium (DSS)-induced colitis and Concanavalin A (Con A)-induced hepatitis. However, the signal transduction pathways involved have not been identified. The present study investigated the effect of leptin-induced STAT3 signaling in the DSS and Con A models. Mice carrying a leptin receptor (LEPR) gene mutant for Y1138 (s/s mice), with abrogated leptin-induced STAT3 signaling, were compared with wild-type (WT) and LEPR-deficient db/db mice. Administration of DSS to s/s mice resulted in a clinical score and colon shortening of intermediate severity compared with disease induced in WT and db/db mice-the latter group having the lowest disease severity. A comparable degree of inflammatory infiltrate and epithelial damage was observed in the colon of WT and s/s mice, and these parameters were reduced in db/db mice. Levels of IFN-gamma, IL-6, IL-10, and TNF-alpha were comparable in the colon of s/s and db/db mice, and a similar trend was observed for CXCL2. s/s and WT mice developed severe liver disease in response to Con A, whereas db/db mice were protected. However, Con A-induced serum IL-6 and TNF-alpha levels in s/s mice mimicked levels observed in db/db rather than WT mice. In conclusion, lack of leptin-induced STAT3 signaling is associated with reduced cytokine production following DSS and Con A administration, but it appears to sensitize mice to the effects of proinflammatory mediators.

Abstract
UNLABELLED OBJECTIVE; To describe the role that primary care physicians can play in early recognition of oral and oropharyngeal squamous cell carcinomas (OOSCCs) and to review the risk factors for OOSCCs, the nature of oral premalignant lesions, and the technique and aids for clinical examination. QUALITY OF EVIDENCE MEDLINE and CANCERLIT literature searches were conducted using the following terms: oral cancer and risk factors, pre-malignant oral lesions, clinical evaluation of abnormal oral lesions, and cancer screening. Additional articles were identified from key references within articles. The articles contained level I, II, and III evidence and included controlled trials and systematic reviews. MAIN MESSAGE Most OOSCCs are in advanced stages at diagnosis, and treatment does not improve survival rates. Early recognition and diagnosis of OOSCCs might improve patient survival and reduce treatment-related morbidity. Comprehensive head and neck examinations should be part of all medical and dental examinations. The head and neck should be inspected and palpated to evaluate for OOSCCs, particularly in high-risk patients and when symptoms are identified. A neck mass or mouth lesion combined with regional pain might suggest a malignant or premalignant process. CONCLUSION Primary care physicians are well suited to providing head and neck examinations, and to screening for the presence of suspicious oral lesions. Referral for biopsy might be indicated, depending on the experience of examining physicians.

Abstract
BACKGROUND Despite pathophysiologic similarities, mucosal remodeling is well described in asthma but not chronic rhinosinusitis (CRS). OBJECTIVE This study attempts to identify mucosal remodeling in CRS and correlate it with clinical information. METHODS Charts and histopathology from 53 CRS patients who underwent functional endoscopic sinus surgery were reviewed. Clinical data and basement membrane (BM) thickness were recorded. BM thickness was graded as 0 (no thickening), 1 (mild thickening), 2 (moderate thickening), or 3 (marked thickening). Control mucosae from ten patients without CRS were analyzed for comparison. RESULTS Duration of CRS symptoms positively correlated with BM thickness (p = 0.007). Also, patients with a markedly thickened BM (score of 3) had a significantly greater duration of CRS symptoms (120 months) compared to patients with a thinner BM (score < or =2) (33 months) (p = 0.010). Markedly thickened BM was associated with increased coincidence of asthma (p = 0.019) and aspirin sensitivity (p = 0.003). No correlation was found between BM thickness and preoperative Lund-MacKay score. There was no statistically significant difference between markedly thickened BM and thinner BM with respect to coincidence of polyps, course of preoperative systemic steroids, estimated blood loss at surgery, and number of prior surgeries. CONCLUSION Increased BM thickness is correlated with prolonged duration of symptoms and the coincidence of asthma. This may indicate paranasal sinus remodeling akin to that which occurs in the bronchioles of persistent asthmatic sufferers.

Abstract
Proliferative verrucous leukoplakia (PVL) is a distinct clinical form of oral leukoplakia defined by its progressive clinical course, changing clinical and histopathologic features, and potential to develop into cancer. PVL behaves in a more aggressive and relentless manner than the more innocuous white oral lesions that it can resemble clinically. We present three cases of PVL that progressed to carcinoma and discuss the histopathologic findings that may either hinder or assist in the diagnosis.

PVL behaves in a more aggressive and relentless manner than the more innocuous white oral lesions that it can resemble clinically. METHODS A PubMed search was conducted which identified studies that examined patients with PVL and reported data meeting inclusion criteria. RESULTS PVL is seen much more frequently in females and most often diagnosed after the sixth decade of life. Tobacco use is not strongly linked to the presence of PVL (63% of patients did not use tobacco products). Most (74%) of the patients with PVL progressed to oral carcinoma. CONCLUSION PVL is a persistent and progressive oral lesion that requires very close follow-up along with early and aggressive treatment to increase the chances of a favorable outcome.

Abstract
BACKGROUND & AIMS Adiponectin (APN) is an adipokine that regulates insulin sensitivity and is anti-inflammatory in atherosclerosis. The goal of this study was to investigate the role of APN in intestinal inflammation. METHODS APN knockout (KO) mice and their wild-type (WT) littermates received dextran sulfate sodium (DSS) or trinitrobenzene sulfonic acid (TNBS) to induce intestinal inflammation. Clinical and histologic scores and proliferation of epithelial cells were assessed. Cytokines and APN levels were measured. Expression of APN and heparin binding epidermal growth factor (HB-EGF) was analyzed by immunohistochemistry. Expression of APN and its receptors, HB-EGF, and basic fibroblast growth factor (bFGF) messenger RNA was assessed by reverse-transcription polymerase chain reaction. Association of serum APN with HB-EGF and bFGF was studied by coimmunoprecipitation. RESULTS APN KO mice are protected from chemically induced colitis; administration of APN restores inflammation. APN is expressed in the colon, luminal APN associates with colonic epithelial cells. In vitro, APN increases production of proinflammatory cytokines from colonic tissue. Expression of colonic APN overlaps with that of bFGF and HB-EGF, which play a protective role in colitis. Circulating APN binds to bFGF and HB-EGF, likely inhibiting their protective activity. Inhibition of EGF receptor signaling, which is required for biologic activity of HB-EGF, restores inflammation in APN KO mice. CONCLUSIONS APN deficiency is associated with protection from chemically induced colitis. APN exerts proinflammatory activities in the colon by inducing production of proinflammatory cytokines and inhibiting bioactivity of protective growth factors. Thus, in colitis, APN exerts an opposite role compared with atherosclerosis.

Abstract
Oral care providers must be aware of the impact of bleeding disorders on the management of dental patients. Initial recognition of a bleeding disorder, which may indicate the presence of a systemic pathologic process, may occur in dental practice. Furthermore, prophylactic, restorative and surgical dental care of patients with bleeding disorders is best accomplished by practitioners who are knowledgeable about the pathology, complications and treatment options associated with these conditions. The purpose of this paper is to review common bleeding disorders and their effects on the delivery of oral health care.

Abstract
Most often, mesotheliomas involve the serosal (serous) membranes of the pleura and peritoneum. Sometimes, mesothelial proliferations are identified in other locations. On very rare occasions, a mesothelioma is found within the tunica vaginalis of the paratesticular region. We report a case of papillary mesothelioma of the tunica vaginalis in a 52-year-old man. Although this lesion had papillary structures lined by a single layer of mesothelial cells with predominantly bland nuclear and cytologic features, there was evidence of a minimal presence of mesothelial cells in the underlying stroma. This combination of benign and semimalignant characteristics can make the diagnosis of such a lesion problematic. We think that a diagnosis of "borderline papillary mesothelioma" can be considered for similar mesothelial proliferations to allow for a possible increase in diagnostic accuracy and provide an enhanced informational platform from which patients and clinicians can benefit.

Abstract
Breast disease is of great concern to patients and health care providers alike. Malignancies of the breast and their various presentations can pose tremendous challenges with respect to early diagnosis and effective treatment. Carcinoma of the breast may appear in several forms and produce one or more ectopic substances. Breast carcinomas that display choriocarcinomatous differentiation and produce human chorionic gonadotropin are very rare. Less than a dozen such cases have been described in the medical literature to date. We report a case of breast carcinoma with choriocarcinomatous features, which is the first to show immunohistochemical evidence of the expression of both estrogen receptor and progesterone receptor. We also discuss the cytopathologic aspects observed and conduct a literature review.

Abstract
Infection with human immunodeficiency virus (HIV) and progression to acquired immune deficiency syndrome (AIDS) are associated with a vide variety of morbidities. Local and systemic diseases can develop in association with HIV infection and may manifest themselves as malignancies of the oropharynx. Advances in HIV management, fueled by increasing understanding of molecular pathogenesis, have resulted in marked changes in the prevalence of oral malignant disease. This paper discusses recent trends in the presentation and treatment of malignancies related to HIV and AIDS with an emphasis on malignancies seen in the oral cavity.

Abstract
Diabetes mellitus (DM) is a major worldwide public health concern. In the United States, 18.2 million people (approximately 6.3% of the population) currently suffer from DM; of those, nearly one-third are undiagnosed. The incidence of DM in the U.S. is expected to double by the year 2010 due to general aging among the population and the epidemic of obesity in the western world. Dental providers must be aware of the rapid changes concerning management of individuals with DM and must understand the significant impact DM has on dental treatment.
