Dental Restorations

Mucosal melanoma of the oral cavity is a rare but highly aggressive neoplasm. However, the clinicians need to be aware of the other and more frequent etiologies of intraoral pigmentation, such as amalgam tattoos. As amalgam has been extensively used for dental restorations and can cause pigmentations in the oral mucosa, this is a differential diagnosis not to be forgotten. We describe the characteristics of these two phenomena and present a case vignette illustrating the differential diagnostic issues. Other causes of intraoral pigmentation are summarized.

The aim of this observational study was to investigate the occurrence of pressure damage caused by endotracheal tubes (ETT) when the tube is repositioned from one corner of the mouth to the other every third day. For the assessment of oral condition and the eventual damage caused by ETT, a modified version of the Oral Assessment Guide (OAG) was used. The oral condition was assessed once per day in all adult patients who were orally intubated with a tube for over 24 hours. Thirty-eight patients were included in the study. Most patients ( n = 33, 86.8%) had no pressure damage. Five patients (13.2%) had pressure damage on the oral mucosa and lip caused by endotracheal tubes. The group with damage to the oral mucosa was treated with noradrenaline, had bleeding problems and clotting disorders and had significantly more intubated and study days. The assessment of the oral mucosa according to the OAG reflected the worsening oral condition in the group with pressure damage. Endotracheal tubes may need to be repositioned more often than every third day to avoid pressure damage in patients with a high risk of complications, and individually tailored care may need to be implemented.

Blistering Disease

Pemphigus vulgaris (PV) is a chronic, autoimmune, intraepidermal blistering disease of the skin and mucous membranes. The first clinical manifestation is often the development of intraoral lesions, and later, the lesions involve the other mucous membranes and skin. The etiological factors of this disease still remain unknown, although the presence of autoantibodies is consistent with an autoimmune disease. A 73-year-old man had bullous lesions on gingiva, oral mucosa first, then scalp, trunk, and face. An oral medicine specialist suspects the lesion in differential diagnosis in the first presentation of oral lesions and follows up the patient, and then these bullous lesions presented on the skin. In this article, a patient had received oral prednisolone (80 mg/kg/day) and azathioprine, then tapered oral prednisolone to 40 mg/day, with a reduction of 5 mg/day every three weeks. The patient shows remission of these lesions, and complication of this treatment includes osteoporosis, hyperglycemia, and hypertension.

Characteristic Features

The oral cavity is considered to be a mirror of the body’s health, as it reflects the manifestations of various systemic disorders. Most of the oral mucosa is derived embryologically from an invagination of ectoderm and thus, like other similar orifices, it may become involved in the disorders that are primarily associated with the skin. Oral submucous fibrosis is one of the commonest precancerous conditions of the oral mucosa involving any part of the oral cavity resulting in tissue scarring, dysphagia and trismus. It is a collagen-related disorder characterized by excessive fibrosis in the oral submucosa, hyalinization and degenerative changes in the muscles. This disease has become a challenging entity for dermatologists due to resemblance of its features to various mucocutaneous conditions. An improper diagnosis can lead to wrong treatment and additional complications. Dermatologists need to be aware of the characteristic features of this disease which can distinguish it from other similar conditions. This review aims to focus on the detailed aspects of oral submucous fibrosis including its historical background, etiological factors, pathogenesis, clinical features, differential diagnosis, investigations, management and future perspectives.

Abstract Tuberculosis (TB) is an epidemic infectious disease that seldom takes an oral form. Because of the still increased incidence of TB in our country, in the differential diagnosis of chronic oral ulcerations, tuberculosis should always be considered. Oral TB is frequently overlooked as a possible cause of oral ulceration. Therefore dentists should be aware of the possible occurrence of TB of the oral cavity.

The purpose of the study is to investigate the electrochemical behavior of two dental alloys: palladium alloy (Palidor) and Ni-Cr alloy (Verasoft) in three types of artificial saliva. Determination of corrosion potential and recording of linear and cyclic polarization curves were performed with PGP201 potentiostat (VoltaLab 21- Radelkis Copenhagen. In order to study the modifications produced on the surface of the electrodes, a complex optical microscope MC 1 research type (IOR, Romania) was used, adapted to a digital camera, which was connected to a computer for the digital acquisition of images . Two metal alloys based on Ag-Pd and Ni-Cr were used for the experiments. The materials used came from different types of dental restorations removed from the oral cavity of the patients after a 5-15 years period. As corrosion environments, three artificial saliva were used: Fusayama, Afnor and Rondelli. The Pd-Ag dental alloy exhibits a very good corrosion resistance and the treatment in the Afnor saliva does not affect the surface of the alloy. Electrochemical behavior in Fusayama-Meyer�s saliva of the alloy surface results in a series of spots representing deposits of insoluble salts resulting from the oxidation process, while in the Rondelli saliva there is a series of small corrosion points on the alloy surface. The behavior of the Verasoft alloy in the Afnor and Rondelli saliva is similar; In both solutions, the potential breakthroughs are very close, but in Fusayama-Meyer�s saliva, the potential for initiation of corrosion points is very low (206 mV), a potential that can be encountered in the oral cavity. All metals and metal alloys, even the noble and semi-precious ones, are susceptible to corrosion, forming compounds with properties different from those of the metal or base alloy, which change their surface condition. Metallic dental restorations are permanently affected by the factors of the oral environment (physical-mechanical, chemical and biological), being subjected to a continuous process of degradation.

Pelvic Masses

Pelvic masses can pose a diagnostic dilemma with a broad differential to include both gynecological and non-gynecologic etiologies. While the initial instinct may be to search for gynecologic causes for the female patient, non-gynecologic etiologies must be considered as well. The presentation can be similar amongst many different causes of pelvic masses and imaging is generally required for further assessment to determine if the mass is intra- or extraperitoneal. The etiology of adnexal masses covers several subspecialties: gynecology, urology, gastroenterology, neurology, and oncology. For this reason, it is important for all to be aware of the differential diagnosis for pelvic masses.

AbstractThe aim of this study was to correlate three commercially available copeptin assays and their diagnostic accuracy in the differential diagnosis of the polyuria-polydipsia syndrome. Analyzed data include repeated copeptin measures of 8 healthy volunteers and 40 patients with polyuria-polydipsia syndrome undergoing osmotic stimulation and of 40 patients hospitalized with pneumonia. Copeptin was measured using the automated Brahms KRYPTOR, the manual Brahms LIA and the manual Cloud Clone ELISA assay. Primary outcome was the interrater correlation coefficient (ICC) and diagnostic accuracy in the polyuria-polydipsia syndrome of the three assays. In healthy volunteers, there was a moderate correlation for the KRYPTOR and LIA (ICC 0.74; 95% CI 0.07 to 0.91), and a poor correlation for the KRYPTOR and ELISA (ICC 0.07; 95% CI − 0.06 to 0.29), as for the LIA and ELISA (ICC 0.04; 95% CI − 0.04 to 0.17). The KRYPTOR had the highest diagnostic accuracy (98% (95% CI 83 to100)), comparable to the LIA (88% (95% CI 74 to 100)), while the ELISA had a poor diagnostic accuracy (55% (95% CI 34 to 68)) in the differential diagnosis of the polyuria-polydipsia syndrome. The KRYPTOR and LIA yield comparable copeptin concentrations and high diagnostic accuracy, while the ELISA correlates poorly with the other two assays and shows a poor diagnostic accuracy for polyuria-polydipsia patients. The current copeptin cut-off is valid for the KRYPTOR and LIA assay. Our results indicate that interpretation with other assays should be performed with caution and separate validation studies are required before their use in differentiating patients with polyuria-polydipsia syndrome.Trial registration: NCT02647736 January 6, 2016/NCT01940614 September 12, 2013/NCT00973154 September 9, 2009.

We were asked to consider differential diagnosis. We decided that it really is different from the other diagnostic modalities and cannot be treated in the same way as, for example, global or neuropsychological measures. In the context of this meeting, we believed it would be appropriate to consider clinical criteria. Thus, clinical criteria for the dementia syndrome as well as for specific diseases were discussed. We recognized that in the future, an increasing number of patients will present with cognitive impairment who do not fulfill the clinical criteria for dementia. These patients may alternatively have an isolated memory impairment syndrome. Nevertheless, a diagnosis will still need to be made in these patients, at least in terms of the underlying molecular pathology, in order to implement potential treatments.
