Abstract
The comprehensive dental rehabilitation of complex prosthetic cases is often associated with increasing occlusal vertical dimension and transferring horizontal mandibular position in centric relation. The newly defined position of the mandibula should be functionally and esthetically evaluated for a longer time period before irreversible measures are performed. This case report discusses in detail a time-saving and economic direct method for increasing occlusal vertical dimension with long-term provisional composite restorations using a simplified injection molding technique and illustrates the complete intraoral and laboratory workflow.

Risk indicators of early childhood caries (ECC) in children with high treatment needs.
Swiss Dent J. 2017;127(5):398-410
Authors: Kraljevic I, Filippi C, Filippi A
Abstract
Early childhood caries (ECC) represents a major health and economic problem worldwide. Its consequences such as early pain experience may affect the immediate and long-term quality of life of the child. In very young and uncooperative children the therapy of ECC is often viable only under general anesthesia. After treatment these affected children have a higher risk for future caries either soon thereafter, or later in life. The aim of the present study was to determine risk indicators and their correlation among children with high caries prevalence and high treatment needs, in order to facilitate the development of targeted prophylaxis programs that would reduce future occurrences of ECC or at least positively influence the outcome. For this purpose, between 2010 and 2014 the parents of these children (n=82) were interviewed in the University Childrens Hospital in Basel (UKBB) prior to the childrens treatment under general anesthesia. The standardized questionnaire included questions regarding the age of the child, the mothers country of origin, the oral hygiene, and the drinking habits of the child. The analysis shows that the high mean dmft/ dmfs values (dmft: 9.49 and dmfs: 26.35) correlated significantly with the geographic origin of the mother (p<0.05), the beginning of tooth brushing (p<0.05), lack of supervised tooth brushing (p<0.01), and nighttime consumption of sugar-sweetened beverages (p<0.05). In contrast, the duration of breastfeeding and prolonged use of a baby bottle (about 2.5 years) did not have a clear impact on high caries prevalence.

Pyostomatitis vegetans Zahlreiche blassgelbe Punkte auf entzündlich rotem Grund.
Swiss Dent J. 2017;127(6):523-537
Authors: Bethke G, Bethke G, Prager M, Purucker P
Abstract
Pyostomatitis vegetans is a disease of the gingiva and the oral mucosa with noticeable, uncommon morphology. Clinical characteristics of this rare disease and considerations regarding differential diagnosis are described. Pyostomatitis vegetans is frequently associated with chronic inflammatory bowel diseases and can, thus, give a diagnostic hint at an existing ulcerative colitis or Crohns disease. A therapy plan for pyostomatitis vegetans is presented, which led to remission using local treatment only. The follow-up examination after one year showed that the treatment outcome had remained stable. An unexpected clinical appearance of the gingiva with small, pale pink thickenings after therapy and at follow-up is portrayed.

Traitement médicamenteux du lichen plan buccal.
Swiss Dent J. 2017;127(6):538-539
Authors: Schenkel JS, Lübbers HT, Rostetter C, Metzler P
Abstract
Oral lichen planus is a relatively common T-cell mediated inflammatory disease with potential malignant transformation. It may present itself with pain and oral lesions such as ulcers and Wickhams striae. Treatment includes topical corticosteroids, preferably Clobetasol, immunosuppressive drugs and retinoids. Hyaluronic acid and aloe vera have been proven to be successful. If topical treatment fails, systemic therapy with corticosteroids may be needed. Because of the potential malignant transformation periodic follow-up is mandatory.

An 18-year-old man presented with spontaneous severe epigastric pain, progressing and radiating to back since 3 days. It was associated with epigastric tenderness, bilious vomiting and jaundice. He had been intermittently experiencing these symptoms for the last 1 year. No known comorbid. Ultrasound showed a poorly visualised heterogeneous focus at porta hepatis; considering poor visualisation, this might represent an enlarged calcified lymph node or cystic duct calculus causing extrinsic compression or a large sludge ball within the common bile duct (CBD), leading to dilatation of common hepatic duct and intrahepatic biliary system. Subsequent magnetic resonance cholangiopancreatography revealed a focal saccular dilatation of middle part of CBD, a type I-B choledochal cyst, large heterogeneous focus seen within it representing choledochocystolithiasis. Later, CT was performed for further characterisation of surrounding anatomy and pathology, which confused the appearance of choledochocystolithiasis for Mirizzi syndrome. Later, surgery and histopathology confirmed type I-B choledochocystolithiasis and chronic cholecystitis.
Pyosalpinx is a severe sequel of chronic pelvic inflammatory disease, whereby the fallopian tubes become filled with pus.1 2 Pyosalpinx often affects sexually active women and rarely is seen in celibate adolescent girls.3 We report a case of a 12-year-old girl with no prior sexual history who presented to our emergency department with complaints of severe right lower quadrant pain of 1-day duration. Ultrasonography and CT scan of the abdomen and pelvis revealed free fluid collections in the pelvis without visualisation of the appendix. A preoperative diagnosis of acute ruptured appendicitis was given and she was taken to the operating room. Peroperative findings included bilaterally distended, pus-filled pyosalpinges. A definitive diagnosis of bilateral pyosalpinx was then made. Two-week antibiotic therapy was successful but the patient returned with recurrent pyosalpinx and a pelvic abscess 9 weeks later.

ObjectivesTransforming growth factor beta1 (TGF-β1) plays a significant role in craniofacial development. Previous linkage studies reported that the TGF-β1-locus at 19q13.1 harbour predisposing genes for non-syndromic oral clefts. In the present study case parents triads were evaluated to find the transmission effects of genetic variants in TGF- β1 towards non-syndromic cleft lip or palate (NSCL/P).MethodsUsing allelic discrimination method148 families (case-parent triads) were assessed for single nucleotide polymorphisms (SNPs) in TGF-β1 gene. The SNPs were checked for mendelian errors and Hardy-Weinberg equilibrium (HWE). Transmission disequilibrium test and haplotype frequencies were estimated.ResultsThe TGF-β1 SNPs showed very low minor allele frequencies (MAFs) and observed heterozygosity (Hobs). The transmission disequilibrium test (TDT) and parent-of-origin likelihood ratio tests (PO-LRT) were not significant for any of the SNPs tested. Strong linkage disequilibrium (r2 = 0.722) was found between rs1800469 and rs1800470 SNPs. Haplotype analysis ignoring parent of origin showed strong evidence of excess transmission but it is not significant (p-value = 0.293).ConclusionTransmission of minor alleles were not observed from either parent indicating that the TGF-β1 gene polymorphisms by themselves do not confer risk for non-syndromic oral clefts but, rather, modify the stability and the activation process of TGF-β1. As the number of families included in the study are less, results must be considered still preliminary and require replication using more families.

ObjectivesTo describe a multicenter study regarding surgical management of bilateral congenital cholesteatoma (BCC) and underline the importance of endoscopes in the management of this condition. In BCC, hearing preservation is more crucial than in unilateral cases. The endoscopic approach allows complete removal of cholesteatoma via a minimally invasive technique offering low residual disease rates while preserving the normal physiology of the middle ear and possibly the ossicular chain.Study designRetrospective chart and surgical video review of patients with BCC who underwent surgery at Otolaryngology Department of Modena and Verona University Hospitals and the Hospital for Sick Children, Toronto.MethodsFrom 2002 to November 2016, six patients were identified with bilateral congenital cholesteatoma and included in this study. Pre-operative assessments, surgical treatments and outcomes were collected and described.ResultsThe median age at presentation was 4 years (range 2–7 years). A microscopic post auricular tympanoplasty was performed in two ears, four underwent a canal wall up mastoidectomy procedure and in the other six a transcanal endoscopic approach (TEA) was used. No intra- or post-operative complications were observed in any patients. The mean follow up period was 54.5 months.ConclusionsWhen both ears are involved with congenital cholesteatoma, it is particularly important to use a minimally invasive technique that preserves normal ossicular and mastoid structure and function whenever possible. In many cases this can be achieved with TEA, even in young children. In addition the endoscope allows good surgical control of cholesteatoma removal from hidden recesses.

CONCLUSIONS: GBC is an uncommon malignancy that presents most often among females in their 8th decade of life, with over a third of cases presenting with distant metastasis. The incidence of GBC has doubled in the last decade concurrent with increases in cholecystectomy rates attributable in part to improved histopathological detection, as well as laparoscopic advances and enhanced endoscopic techniques. Surgical resection confers significant survival benefit in GBC patients. PMID: 28638176 [PubMed - in process] (Source: HPB Surgery)

Authors: Takamura T, Suguro H, Mikami Y, Iwase T, Komiyama Y, Kuyama K, Komiyama K, Oki H Abstract Secretory leukocyte protease inhibitor (SLPI) is a serine protease inhibitor whose expression level is positively correlated with tumor aggressiveness and metastatic potential. However, the mechanism underlying SLPI-induced enhancement of malignant phenotype is not completely understood. The malignancy of cancer cells is highly dependent on cell migration activity. Our previous study revealed that gingival carcinoma Ca9-22 cells, but not colorectal adenocarcinoma HT-29 cells, expressed SLPI. Therefore, we investigated the migration activity of these two cell types to understand the nature of SLPI-mediated tumor aggressiveness and metastatic potential. In vitro wound healing assay indi...

ConclusionThe relatively high proportion of EV patients without mutation in TMC6/8 indicates the existence of EV‐causing mutations in additional, presently unknown gene(s). However, a homozygous TMC8 splice site mutation in our patients resulted in aberrant transcripts which cannot retain the healthy phenotype. The literature review revealed that HPV‐5 is the most commonly identified HPV in EV patients, but HPV‐3, HPV‐14, and HPV‐20 were unexpectedly identified more frequently than HPV‐8.This article is protected by copyright.

AbstractPurpose of ReviewWe review the existing scientific literature regarding skin cancer in Hispanics to aid in formulating a research agenda for prevention targeted to this at-risk population.Recent FindingsHispanics are a diverse population with a rising incidence of both melanoma and non-melanoma skin cancer. Compared with non-Hispanic whites, Hispanics have poorer disease outcomes and higher rates of acral lentiginous melanoma, an aggressive subtype. Hispanics practice suboptimal sun protection and skin surveillance behaviors and experience rates of sunburn comparable with non-Hispanic whites. Despite these risk behaviors, little skin cancer education and prevention has been targeted to this population.SummaryFurther research is warranted to understand the interplay of biological, p...

Abnormal expression of chondroitin sulfate has been found in many types of cancer, while its biological functions in hepatocellular carcinoma (HCC) progression remain uninvestigated. Here, we report that chondroitin sulfate synthase 1 (CHSY1), the enzyme that mediates the polymerization step of chondroitin sulfate, is a critical mediator of malignant character in HCC that acts via modulating the activity of the hedgehog signaling. CHSY1 was up-regulated frequently in HCC where these events were associated with worse histologic grade and poor survival. (Source: Cancer Letters)

Circulating tumor cells (CTCs) enter the vasculature or lymphatic system after shedding from the primary tumor. CTCs may serve as "seed" cells for tumor metastasis. The utility of CTCs in clinical applications for sarcoma is not fully investigated, partly owing to the necessity for fresh blood samples and the lack of a CTC-specific antibody. To overcome these drawbacks, we developed a technique for sarcoma CTCs capture and detection using cryopreserved peripheral blood mononuclear cells (PBMCs) and our proprietary cell-surface vimentin (CSV) antibody 84-1, which is specific to tumor cells.

I recently received an email from a former resident and now colleague in which he lamented the shifts in practice patterns occurring in many oral-maxillofacial surgery offices. His primary focus related to orthognathic surgery. His basic fear is that technological advances involving the digital workflow approach to the diagnosis and treatment planning for managing dental deformities opens the door for surgeons with no dental background to treat these conditions. He worries that those who are not oral-maxillofacial surgeons (OMSs) will fill a vacuum he sees existing in the willingness of OMSs to do orthognathic surgery.

An alveolar bone grafting that enable tooth eruption, orthodontic tooth movement, and non-prosthetic restoration of dentition at the alveolar cleft site has been performed at many institutions as a part of the standard treatment for cleft lip and palate patients since the report of fresh autogenous bone grafting was published1. Conventionally, an alveolar bone grafting is performed using particulate cancellous bone and marrow (PCBM) frequently harvested from the iliac crest2,3. However, because of the invasiveness of iliac crest bone graft harvesting, postoperative complications such as pain, gait disorder, and sensory nerve paralysis have been reported from time to time4-6.

Solitary papilloma is a human papillomavirus (HPV) induced benign indolent epithelial tumor with limited growth, whereas papillomatosis is an entirely different story. Papillomatosis needs attention due to its aggressive and recurrent clinical progress with risks of dysplastic and malignant transformation. Recurrent respiratory papillomatosis (RRP) has a high prevalence of dysplasia and reports of transformation to carcinoma-ex-papillomatosis, especially when associated with low risk HPV type 11.

Reduction malarplasty is one of the most common aesthetic surgeries performed in the Asian population. Traditional procedures have several complications such as bone non-union, malunion, cheek drooping, and damage to the infraorbital nerve and maxillary sinus. Therefore, a more straightforward and effective method of reducing the width of the midface is needed. In the present study, we introduce an infracture technique using the inward displacement of the zygomatic arch without fixation. (Source: Journal of Oral and Maxillofacial Surgery)

Lung cancer is the leading cause of cancer deaths worldwide. It is an aggressive and devastating cancer because of metastasis triggered by enhanced migration and invasion, and resistance to cytotoxic chemotherapy. The epithelial to mesenchymal transition (EMT) is a fundamental developmental process that is reactivated in wound healing and a variety of diseases including cancer where it promotes migration/invasion and metastasis, resistance to treatment, and generation and maintenance of cancer stem cells. The induction of EMT is associated with reprogramming of the epigenome. This review focuses on major mechanisms of epigenetic regulation mainly in lung cancer with recent data on EZH2 (enhancer of zeste 2 polycomb repressive complex 2 subunit ), the catalytic subunit of the PRC2 (Polycomb...

The effectiveness of cancer therapy is one of the main challenges in cancer treatment. Cancer resistance to chemotherapy, radiotherapy, and targeted therapies may be inherent or acquired, and ultimately drives tumor relapse and poor treatment outcomes. In many cases, advanced cancer patients eventually fail to respond to treatment or experience tumor relapse due to the expansion of drug-resistant tumor cell populations [1].

Cancer induction is a highly complex process involving hundreds of different inducers but whose eventual outcome is the same. Clearly, it is essential to understand how signalling pathways and networks generated by these inducers interact to regulate cell behaviour and create the cancer phenotype. While enormous strides have been made in identifying key networking profiles, the amount of data generated far exceeds our ability to understand how it all "fits together". The number of potential interactions is astronomically large and requires novel approaches and extreme computation methods to dissect them out. (Source: Critical Reviews in Oncology Hematology)

Soon after the discovery of microRNAs over 15 years ago, a myriad of research groups around the world sought to develop clinical applications in breast cancer for these short, noncoding, regulatory RNAs. While little of this knowledge has translated into the clinic, the recent research explosion on cell-to-cell communication via exosomes and other extracellular vesicles has rekindled interest in microRNA-based clinical applications. microRNAs appear to be a preferential and important cargo of exosomes in mediating biological effects in recipient cells. This review highlights recent studies on the biology of exosomal microRNAs (exo-miRNAs) and discusses potential clinical applications. From a diagnostic perspective, circulating exo-miRNAs may represent breast cancer cell content and/or tumo...

ConclusionThe large variety of particles, techniques, and treated tumors in the studies provided an important insight into issues concerning efficacy, safety, particle and isotope choice, and other concepts for future research. Animal studies showed efficacy and a dose response. Most studies in humans concluded that intratumoral treatment with radioactive beta-emitting microparticles is relatively safe and effective. Conflicting evidence about safety and efficacy might be explained by the considerable variation in the treatment characteristics. Larger particles had a better retention which resulted in higher anti-tumor effect. Leakage seems to follow the path of least resistance depending on anatomical structures. Subsequently, a grid-like injection procedure with small volume depots is ad...

The past few decades have seen a significant rise in the use of cell lines in molecular oncology. Most researchers purchase cell lines from commercial laboratories. Thus it is vital to analyze the factors influencing the phenotypic and genotypic characteristics of the purchased cell lines prior to the study. At present most laboratories employ immortalization to increase the productivity of the cell lines. Although immortalization increases the life span of the cell lines and provides additional time for the researcher, there are few drawbacks to immortalization. (Source: Oral Oncology)

The term OLD is used to designate a primary oral epithelial dysplasia with secondary lichenoid features [1]. An OLD may be unilateral or bilateral in the presentation. Can exhibit clinical patterns similar to the various types of oral lichen planus ranging from the most common reticular type to the rare bullous variant. OLD may also show features similar to oral leukoplakia (flat white patch). OLD histopathology consists of 2 components: epithelial dysplasia and lichenoid features. The dysplastic features may range from mild to severe based on the World Health Organization (WHO) grading of oral epithelial dysplasia [2]. (Source: Oral Oncology)

Unstable cytokeratins are associated with tumor transformation in the development of human hepatocellular carcinoma. We previously demonstrated that the cytokeratin 18 was modulated and that a histone H3-specific modification occured, among members of the histone family, during the development of human hepatocellular carcinoma. Evidence suggested that the modification of histone H3 was highly correlated with the modulation of cytokeratin 18 and probably plays an important role in tumorigenesis of hepatocytes. Aberrant expression of histone deacetylase leading to imbalance between acetylation and deacetylation of histones may exhibit regulatory roles in tumor transformation. Recently we found that overexpression of histone deacetylase-1 and hypoacetylation of histone H3 were associated with...

Compared to normal cells, cancer cells have a unique metabolism by performing lactic acid fermentation in the presence of oxygen, also known as the Warburg effect. Researchers have proposed several hypotheses to elucidate the phenomenon, but the mechanism is still an enigma. In this review, we discuss three typical models, such as "damaged mitochondria", "adaptation to hypoxia", and "cell proliferation requirement", as well as contributions from mass spectrometry analysis toward our understanding of the Warburg effect. Mass spectrometry analysis supports the "adaptation to hypoxia" model that cancer cells are using quasi-anaerobic fermentation to reduce oxygen consumption in vivo. We further propose that hypoxia is an early event and it plays a crucial role in carcinoma initiation and deve...

We present a case of type A thymoma with invasion of the left brachiocephalic vein and lung metastases. An 84-year-old man underwent extended thymectomy combined with left brachiocephalic vein reconstruction and resection of a lung metastasis. Histological examination showed vascular invasion by the tumor. The lung metastasis had high mitotic activity and slight nuclear enlargement, the so-called "atypical" features, but the main part of the primary tumor did not. However, the intravascular portion of the tumor had "atypical" histological features like the lung metastasis. It seems that "atypical" histological features are related to clinically malignant behavior. (Source: General Thoracic and Cardiovascular Surgery)
