Ola M Ezzatt, Iman M Helmy
OBJECTIVES: Oral lichen plans (OLP) is a potentially malignant inflammatory mucocutaneous disease. CD133 is an investigated surface marker for cancer stem-like cells (CSCs) that may be involved in tumor initiation in head and neck carcinomas. We compared short-term clinical effectiveness of topical pimecrolimus as selective inflammatory cytokine release inhibitor with betamethasone cream for erosive/atrophic OLP and investigated the influence of this therapy on CD133 expression. MATERIAL AND METHODS: Thirty patients were randomly assigned into two equal groups to receive topical pimecrolimus (group I) or betamethasone (group II) four times daily for 4 weeks...

Arpan Tahim, Sarah Ali, Leo Cheng
INTRODUCTION: The aim of surgical management of benign facial skin lumps is to remove the lesion in its entirety, with minimal damage to adjacent tissue structures, while maintaining facial aesthetics. A method to achieve these goals is to remove peri-oral lesions in the labial and buccal zones via an intra-oral approach. We report an extended cases series of facial skin lumps that were excised using an intra-oral approach. METHODS: A retrospective analysis was performed on all patients who underwent excisions of benign cutaneous lesions on the face via an intra-oral approach...

REVIEW
Allison A Gockley, Kevin M Elias
Ovarian cancer remains the leading cause of gynecologic cancer death among American women. Prevention is the only proven approach to reduce the incidence of the disease. Oral contraception, tubal ligation, and risk-reducing salpingo-oophorectomy (rrBSO) for high-risk groups are all established risk reduction strategies. This paradigm is changing as recent biologic studies suggest that many ovarian cancers, especially high-grade serous ovarian cancers, originate in the distal end of the fallopian tube rather than the ovarian surface epithelium...

OBJECTIVE: Fibrous dysplasia (FD) is a benign bone disease characterized by fibro-osseous lesions. FD is caused by somatic mutations in the gene, guanine nucleotide-binding protein, alpha stimulating activity polypeptide 1 (GNAS), which encodes the G protein subunit, Gsα. FD manifests early in life, but the growth of lesions usually ceases in adulthood. FD lesions often exhibit somatic mutation mosaicism. In this study, the relationship between lesion growth and mutation prevalence within a lesion was investigated...

Infantile hemangiomas (IH) are the most common in the head and neck region.1 They can occur anywhere in the skin, however, urethral hemangiomas are very rare. We describe a case report of a three years old boy with extensive lesions of IH in the anterior urethra. Urethral IH were disappeared during one year of oral administration of propranolol though it brought on urinary retention. This is the first report about oral propranolol treatment in a child with urethral IH. Oral administration of propranolol may be effective for urethral IH and beneficial especially for lesions requiring extensive surgical resection and reconstruction...

With the aim of developing early diagnostic/prognostic markers for oral cancer, desmosomal adhesion in sequentially progressive grades of tissues from oral normal/disorders (normal, hyperplastic, dysplastic, non-metastatic/metastatic tumours, and metastatic nodes) was investigated at protein and ultrastructural levels using immunohistochemistry and transmission electron microscopy, respectively. The expression of desmosomal proteins was higher in hyperplastic tissues than in normal tissues but was significantly decreased in subsequent progressive stages of the disease...

Elio Clemente Agostoni, Marco Longoni
Migraine is a common type of headache in young adults, with an estimated prevalence of 4% before puberty and as high as 25% in women by their mid to late 30s. About one third of migraineurs experience transient neurological symptoms known as auras, which characterize a variant known as migraine with aura. Many evidences have shown an increased risk of vascular events in patients affected by migraine, particularly among women and among migraine patients with aura. Potential underlying mechanisms include endothelial dysfunction, hypercoagulability, platelet aggregation, vasospasm, cardiovascular risk factors, paradoxical embolism, spreading depolarization, shared genetic risk, use of non-steroidal anti-inflammatory drugs, and immobilization...

Early detection of oral cancer and oral premalignant lesions (OPLs) containing dysplasia could improve oral cancer outcomes. However, general dental practitioners have difficulty distinguishing dysplastic OPLs from confounder oral mucosal lesions in low-risk populations. We evaluated the ability of two optical imaging technologies, autofluorescence imaging (AFI) and high-resolution microendoscopy (HRME), to diagnose moderate dysplasia or worse (ModDys+) in 56 oral mucosal lesions in a low-risk patient population, using histopathology as the gold standard, and in 46 clinically normal sites...

REVIEW
Edgar Francisco Carrizales-Sepúlveda, Alejandro Ordaz-Farías, Raymundo Vera-Pineda, Ramiro Flores-Ramírez
Periodontal and cardiovascular disease are both major health issues. Poor oral health has long been associated with the development of systemic diseases, with the typical example being the risk of endocarditis posterior to dental procedures. Through the years, the association of periodontal disease with other non-infectious systemic diseases has been brought to attention. One of the most interesting associations is the one that exists with the development of cardiovascular disease. Many studies, including systematic reviews and meta-analyses, suggest an important association between periodontal disease and ischaemic heart disease, cerebrovascular disease, heart failure, atrial fibrillation and peripheral artery disease...

  Two adult sibling red-handed tamarins ( Saguinus midas) presented with weight loss and multifocal skin masses. A skin biopsy revealed pyogranulomatous dermatitis with intrafollicular Demodex sp. mites. Subsequent skin scrapes confirmed the presence of live mites within lesions. Initial treatment with topical and oral ivermectin was unsuccessful, and lesions continued to progress. A single dose of fluralaner (Bravecto®, Merck Animal Health, Kenilworth, New Jersey, 07033, USA; 28.125 mg po) was administered to each animal approximately 5 mo after initial presentation...

PURPOSE: To improve imaging, a reliable setup method is critical for the accurate localization of lesions and surface markers. Because an anisotropic marker has not yet been validated for MRI, direct localization of surface markers is not yet feasible in fractional anisotropy (FA) maps. This study aimed to develop an anisotropic surface marker using wood for an FA map and to determine whether a wood marker is useful for various sequences. METHODS: Wood infiltrated with water was used to develop an anisotropic surface marker...

Herpes simplex viruses (HSVs) are difficult to sequence due to their large DNA genome, high GC content, and the presence of repeats. To date, most HSV genomes have been recovered from culture isolates, raising concern that these genomes may not accurately represent circulating clinical strains. We report the development and validation of a DNA oligonucleotide hybridization panel to recover nearly complete HSV genomes at abundances up to 50,000-fold lower than previously reported. Using copy number information on herpesvirus and host DNA background via quantitative PCR, we developed a protocol for pooling for cost-effective recovery of more than 50 HSV-1 or HSV-2 genomes per MiSeq run...

INTRODUCTION: Habitual toothbrushing with fluoridated toothpaste followed by rinsing with antibacterial mouthwashes is a method to maintain good oral hygiene and to diminish the occurrence and severity of dental caries and periodontal disease. However, our understanding of how antimicrobial agents in mouthwashes affect fluoride-mediated caries lesion remineralization is still poor. OBJECTIVE: The objectives of this in vitro study were a) to determine the effects of the waiting period of chlorhexidine (CHX) rinsing after fluoride toothpaste use and b) to further determine the effect of the type of toothpaste surfactant [sodium dodecyl sulfate (SDS) or cocamidopropyl betaine (CAPB)] on caries lesion remineralization associated with CHX rinsing...

APX3330 is a selective inhibitor of APE1/Ref-1 redox activity. In this study, we investigate the therapeutic effects and underlying mechanisms of APX3330 treatment in type one diabetes mellitus (T1DM) stroke rats. Adult male Wistar rats were induced with T1DM and subjected to transient middle cerebral artery occlusion (MCAo) and treated with either PBS or APX3330 (10mg/kg, oral gavage) starting at 24h after MCAo, and daily for 14 days. Rats were sacrificed at 14 days after MCAo and, blood brain barrier (BBB) permeability, ischemic lesion volume, immunohistochemistry, cell death assay, Western blot, real time PCR, and angiogenic ELISA array were performed...

Following breast and lung cancers, renal cell carcinoma (RCC) is the third most frequent cancer to metastasize to the head and neck region, though such cases are rarely reported. Distinguishing between malignant tumors of salivary gland origin and metastatic RCC is very important. The case of a 75-year-old man with an oral cavity lesion in the left buccal submucosa measuring 40×30 mm that had grown substantially over several weeks is presented. His medical history included left kidney cancer 26 years earlier and a malignant myoepithelioma of the left buccal region 7 years earlier...

Oral lesions can have widely variable aetiology, hence, the importance of a comprehensive history and oral examination. We describe the case of a 47-year-old man who presented with an incidental erythematous lesion of the soft palate. The diagnosis was established during a routine dental examination. We found the lesion to be associated with the practice of fellatio. Oral sex is a very common sexual practice, and as clinicians we should consider it as a potential cause of palatal lesions in our differential diagnosis...

Glomerulonephritis (GN) is a typical lesion in autoantibody and immune complex disorders, including SLE. Because the Gas6/Axl pathway has been implicated in the pathogenesis of many types of GN, targeting this pathway might ameliorate GN. Consequently, we have studied the efficacy and mechanism of R428, a potent selective Axl inhibitor, in the prevention of experimental anti-GBM nephritis. Axl upregulation was investigated with Sp1/3 siRNA in the SV40-transformed mesangial cells. For Axl inhibition, a daily dose of R428 (125 mg/kg) or vehicle was administered orally...

Hypogonadism may be suspected if puberty is delayed. Pubertal delay may be caused by a normal physiological variant, by primary ovarian insufficiency (Turner syndrome), or reflect congenital hypogonadotropic hypogonadism (HH; genetic) or acquired HH (brain lesions). Any underlying chronic disease like inflammatory bowel disease, celiac disease, malnutrition (anorexia or orthorexia), or excessive physical activity may also result in functional HH. Thus, girls with delayed puberty should be evaluated for an underlying pathology before any treatment, including oral contraception, is initiated...

Lingual nerve (LN) injury is one of the most serious consequences of oral surgery. Prompt microsurgical reconstruction of the nerve can alleviate most of those symptoms leading to satisfactory functional recovery.Thirty-five patients with partial to complete LN injury underwent surgery in the period between January 2006 and May 2015. All patients underwent a preoperative clinical and neurological evaluation with the assessment of lingual tactile and pain sensory thresholds and masseteric inhibitory reflex.All patients underwent explorative surgery and direct microneurorrhaphy of distal and proximal stumps in case of complete lesion, while the removal of traumatic neuroma and the following microneurorrhaphy of distal and proximal stumps of the injured nerve was performed in case of incomplete lesion...
