Efficacy of a Non-addictive Nasal Irrigation Based on Sea Salt Enriched with Natural Enzymes among Patients with Sinusitis: An In Vivo, Randomized, Controlled Trial

BACKGROUND: Chronic rhinosinusitis (CRS) is a common condition that is defined as inflammation of the nose and paranasal sinuses. Nasal irrigation plays an important role in the treatment of CRS. Evidence from basic research favors hypertonic saline over isotonic saline for mucociliary clearance, but evidence from clinical studies is controversial. AIM: This study aims to investigate the hypothesis that the use of daily nasal irrigation based on sea salt, enriched with natural enzymes and lysozyme, may be useful in patients with CRS. PATIENT AND METHODS: Patients (30 men and 30 women) 18–55 years old (mean age 41 ± 3 y.o.), with two episodes of acute sinusitis or one episode of chronic sinusitis per year for 2 consecutive years, were enrolled stratified by sex and age and randomly divided into two groups supplementation: Group A (test) and Group B (control/ placebo). Moreover, an exit questionnaire was asked to Group A subjects to report whether their sinus-related quality of life has gotten worse, stayed the same, or improved (scale from 0 to ±100%). RESULTS: The result showed that in the test group (A) from T0 to T1, a reduction of 17.65% for the symptoms related headache and/or facial pressure and a reduction of the 18.18%, for the symptoms relates to congestion and/ or nasal discharge. On the other hand, the control group (B) shown less difference between T0 and T1. CONCLUSIONS: This study strengthens the argument that the tested formulation is a safe, well-tolerated, long-term therapy that patients with chronic sinonasal complaints can and will use at home with minimal training and follow-up

Focus on the cariogenic process: microbial and biochemical interactions with teeth and oral environment

This paper aims to describe the biochemical interactions between teeth and the oral environment that occur during the caries process, hence it covers all the steps related to physico-chemical reactions, including the most up-to-date theoretical basis in the clinical application for the prevention and treatment of caries. The terms 'demineralization' and 'remineralization' that characterise this process were analysed, as well as the role of the microbiota in its interaction with the hard surface of the teeth. The biochemical mechanisms that lead to the onset of carious lesions and those that occur during the healing and repair of such lesions are listed

Fibrolipoma gigante de la mejilla: a propósito de un caso

El fibrolipoma es una neoplasia de origen mesenquimal, rara en la cavidad oral, representando el 1% de todos los tumores benignos orales. Es una variante histológica del lipoma simple, que normalmente se manifiesta a nivel de la mucosa oral, suelo de la boca, lengua y labios. La etiología suele ser traumática cuando afecta localizaciones extraorales, mientras se considera idiopática al manifestarse a nivel bucal. En este artículo se presenta un raro caso de fibrolipoma de mejilla, y se discuten los aspectos diagnósticos, histo-patológicos y de tratamiento de acuerdo a la literatura. Lipomas are common soft tissue mesenchymal neoplasms, rare in the oral cavity, representing 1% of all benign oral tumors. Fibrolipoma is a histological variant of the classic lipoma which normally affects buccal mucosa, floor of the mouth, tongue and lips. In this article is presented a rare case of fibrolipoma of the cheek and are discussed all the aspects of diagnosis, histology and surgical treatment, according to literature data

Peripheral giant cell granuloma: immunohistochemical analysis of different markers. Study of three cases

El granuloma periférico de células gigantes (GPCG) es una lesión de tejido blando no neoplásica ocasionada por una reacción hiperplásica a consecuencia de un traumatismo o inflamación. Es una lesión reactiva del tejido blando que se desarrolla exclusivamente en la cavidad oral y con una ligera predilección en el sexo femenino. La localización habitual de GPCG es en la región de los premolares y la mucosa de la cresta alveolar edéntula. Se presentan tres casos con GPCG (dos hombres y una mujer) con una edad comprendida entre los 25 y 35 años. Todos los pacientes se trataron con resección quirúrgica y ninguno sufrió recidivas. Con el propósito de determinar el posible origen de las células estromales mononucleares y de las células gigantes multinucleares, las muestras de cada caso se estudiaron mediante inmunohistoquímica (marcadores CD-68, CD-34 y α-1 antitripsina) con el fin de evaluar la expresión del linaje endotelial y del linaje monocito/macrófago. Los resultados inmunohistoquímicos mostraron una marcada positividad difusa de CD-68 en las células estromales mononucleares y en las células gigantes multinucleadas. Estas últimas resultaron ser inmunonegativas para CD-34 y sólo puntualmente positivas para α-1 antitripsina. Estos resultados sugieren que las cιlulas gigantes multinucleares poseen un fenotipo osteoclαstico, proviniendo del linaje monocito/macrσfago, y que no derivan del linaje de las células endoteliales de los capilares. Se establece la importancia de un exhaustivo diagnóstico y de una exéresis quirúrgica completa de la lesión (curetaje óseo) con el propósito de evitar la reabsorción del diente y hueso adyacente

Jacob’s Disease: Case Series, Extensive Literature Review and Classification Proposal

Jacob’s disease is a rare entity consisting of the formation of a pseudojoint between an abnormal coronoid process of the mandible and the inner surface of the zygomatic bone. First described by Jacob in 1899, its diagnosis and definition have never been entirely univocal. In this paper, we present three emblematic cases and an extensive review of the literature on Jacob’s disease. Given the variability observed in the presentation of the disease, we have developed a proposal for the classification, here reported

Update on gingival overgrowth by cyclosporine A in renal transplants

Severe gingival overgrowth is one of the most frequent side effects in renal transplant patients associated with assumption of cyclosporine A. Several associations with age, sex, dosage, duration of therapy or interval since transplantation have been hypothesized. The introduction of alternative immunosuppressant drugs have been suggested to permit better long-term transplant outcomes and a decrease in incidence of gingival overgrowth. The aim of the present paper is to summarize current knowledge regarding aetiology, pathogenesis and management of gingival overgrowth induced by Cyclosporine A

Peripheral Purinergic Modulation in Pediatric Orofacial Inflammatory Pain Affects Brainstem Nitroxidergic System: A Translational Research

Physiology of orofacial pain pathways embraces primary afferent neurons, pathologic changes in the trigeminal ganglion, brainstem nociceptive neurons, and higher brain function regulating orofacial nociception. The goal of this study was to investigate the nitroxidergic system alteration at brainstem level (spinal trigeminal nucleus), and the role of peripheral P2 purinergic receptors in an experimental mouse model of pediatric inflammatory orofacial pain, to increase knowledge and supply information concerning orofacial pain in children and adolescents, like pediatric dentists and pathologists, as well as oro-maxillo-facial surgeons, may be asked to participate in the treatment of these patients. The experimental animals were treated subcutaneously in the perioral region with pyridoxalphosphate-6-azophenyl-2′,4′-disulphonic acid (PPADS), a P2 receptor antagonist, 30 minutes before formalin injection. The pain-related behavior and the nitroxidergic system alterations in the spinal trigeminal nucleus using immunohistochemistry and western blotting analysis have been evaluated. The local administration of PPADS decreased the face-rubbing activity and the expression of both neuronal and inducible nitric oxide (NO) synthase isoforms in the spinal trigeminal nucleus. These results underline a relationship between orofacial inflammatory pain and nitroxidergic system in the spinal trigeminal nucleus and suggest a role of peripheral P2 receptors in trigeminal pain transmission influencing NO production at central level. In this way, orofacial pain physiology should be elucidated and applied to clinical practice in the future
