[Salivary gland disorder: consider IgG4-related disease]. / Speekselklierafwijking: denk aan IgG4-gerelateerde ziekte.

A 73-year-old man was presented with painless, bilateral swelling of the submandibular salivary glands and unilateral swelling of the parotid gland on the right side, and complaints of dry mouth. A parotid biopsy was taken and a serologic exam was carried out, resulting in the diagnosis of IgG4-related disease. IgG4-related disease is a rare systemic disorder that can cause symptoms in the head and neck region. Usually there are complaints of bilateral, painless swelling of the submandibular, parotid and/or lacrimal glands, with or without complaints of dryness of the mouth and eyes.

Success rate of sialendoscopy. A systematic review and meta-analysis.

OBJECTIVE: To perform a systematic review and meta-analysis on the efficacy and safety of sialendoscopy in the treatment of obstructive diseases of the major salivary glands. MATERIALS AND METHODS: We searched four databases for literature. The primary outcome assessed was the success rate. Secondary outcomes included the use of supportive devices, number of sialadenectomies and complications. Risk of bias was assessed. Meta-analyses with subgroup analysis were performed. RESULTS: In total, 91 studies were included, comprising 8218 patients undergoing 9043 sialendoscopic procedures. The majority of studies had a medium or high risk of bias. The incidence of sialadenectomy varied from 0% to 14%. No major complications were reported. Meta-analysis revealed a weighted pooled success rate of 80.9%. Subgroup analyses showed the weighted pooled success rate in patients with sialoliths (89.6%), stenoses (56.3%), submandibular glands (88.3%), parotid glands (81.2%), patients treated by an endoscopic-assisted transoral removal of a sialolith (86.3%), patients treated by a combined approach of the parotid gland (78.2%), patients with JRP (67.0%) and with RAIS (45.8%). CONCLUSION: The success rate of sialendoscopy did not considerably change in the last 9 years. Sialendoscopy is an efficient and safe procedure for the treatment of major salivary gland obstructive disease.

Harvesting anterior iliac crest or calvarial bone grafts to augment severely resorbed edentulous jaws: a systematic review and meta-analysis of patient-reported outcomes.

The aim of this systematic review was to compare patient-reported outcomes after harvesting calvarial or anterior iliac crest bone grafts to repair severe jaw defects and enable implant placement. The MEDLINE, Embase, Cochrane Central Register of Controlled Trials databases, and OpenGrey were searched for studies on patient satisfaction, pain, disturbances in daily functioning, sensory alterations, donor site aesthetics, and complication rates. Of the 1946 articles identified, 43 reporting 40 studies fulfilled the inclusion criteria; the studies were one randomized controlled clinical trial, one retrospective controlled clinical trial, and 23 prospective and 15 retrospective cohort studies. A meta-analysis of two studies (74 patients) showed no difference in satisfaction (mean difference (MD) - 0.13, 95% confidence interval (CI) - 1.17 to 0.92; P = 0.813) or postoperative pain (directly postoperative: MD -2.32, 95% CI -5.20 to 0.55, P = 0.113; late postoperative: MD -0.01, 95% CI -0.14 to 0.11, P = 0.825) between donor sites. However, the level of evidence is limited, due to the retrospective, non-randomized design of one study. Postoperative gait disturbances were highly prevalent among the anterior iliac crest patients (28-100% after 1 week). The incidence rates of sensory disturbances and other complications were low, and the donor site aesthetic outcomes were favourable for both graft types. To conclude, harvesting bone grafts from the calvarium or anterior iliac crest to augment the severely resorbed edentulous jaw results in similar patient satisfaction. However, the findings for postoperative pain and disturbances in daily living suggest a trend in favour of calvarial bone grafts if harvested using an adjusted technique.

Patient-reported aesthetic outcomes of upper blepharoplasty: a randomized controlled trial comparing two surgical techniques.

It is not yet established whether additional orbicularis oculi muscle excision leads to better patient-reported aesthetic outcomes (PRO) compared to a skin-only resection blepharoplasty. A double-blind randomized controlled trial of upper blepharoplasty, with or without muscle excision, was performed on 54 White European patients who assessed the procedure via PRO. FACE-Q questionnaires covering eyes in general, upper eyelids, forehead and eyebrows, overall face, age appearance appraisal, age appraisal, social functioning, satisfaction with the outcome, and adverse effects were completed preoperatively and at 6 and 12 months after upper blepharoplasty. The Patient and Observer Scar Assessment Scale was used to assess scarring. The FACE-Q scores for skin-only and skin/muscle upper blepharoplasty were similar regarding the upper eyelids, forehead and eyebrows, overall face, patient perceived aging and age, social functioning, and satisfaction with the results, and also increased for both procedures with time. The FACE-Q score regarding the eyes in general was higher in the skin-only group at the 12-month follow-up. Scarring and adverse effects did not differ between the groups. Additional muscle resection does not seem to influence patient satisfaction. Thus, when performing an upper blepharoplasty, there is no need for additional muscle resection as a routine procedure to improve patient satisfaction.

[Oral self-mutilation: a repetitive tongue trauma]. / Orale automutilatie: een repetitief tongtrauma.

An 18-year old woman was referred to the department of oral and maxillofacial surgery with 1 to 2 week episodes of tongue ulcerations that had lasted for a year. Food intake was limited due to pain, resulting in a loss of 10 kg during the previous year. Following a clinical diagnosis of 'aphthous ulcers', she was treated with tetracycline and clobetasol mouthwash, which had little effect. An injection with triamcinolone acetonide did not prove effective either. Some time later, the patient reported at the emergency department with a deep, ulcerative wound to the tongue with characteristic features of bite trauma. She said she had consistently worn her protective mouthguard. The symptoms suggested self-mutilation. The patient was admitted to a psychiatric department, where a diagnosis of anxiety disorder and self-mutilation was reached.

[The level of oral health and oral care in patients with Sjögren syndrome]. / Het niveau van de mondgezondheid en mondverzorging van patiënten met het syndroom van Sjögren.

Sjögren syndrome, characterised by, among other things, dry mouth, can be associated with an increased risk of caries and oral infections. The level of oral care and oral health in a group of 50 patients with Sjögren syndrome was assessed. These findings were compared with a group of 61 healthy controls. Damage to the cervical area of the teeth was much more frequently seen in patients with Sjögren syndrome than in the control group (p smaller 0,001). Moreover, patients with Sjögren syndrome paid more attention to their oral care. This expressed itself, among other things, by the more frequent use of interdental cleaning agents (p = 0.004) and fluoride mouthwashes (p smaller 0.001). It is recommended that dentists and dental hygienists see their patients often; every three months, for example, on account of, among other things, the increased risk of developing caries.

Measuring the social impact of dental research: An insight into the most influential articles on the Web.

OBJECTIVES: To identify the most discussed dental articles on the Web and to assess the association between the intensity of online attention, publication characteristics, and citations. MATERIALS AND METHODS: An Altmetric Explorer search was conducted for articles published in the 91 dental journals included in 2015 InCites™ Journal Citation Report® and mentioned online at all times. The 100 articles with the highest online attention, as measured by the "Altmetric Attention Score" (AAS), were screened for journal title, quartile of impact factor distribution (Q1-Q4), publication date, origin and affiliation of first author, article topic, type, and access. Citation counts were harvested from Scopus. RESULTS: The top 100 articles presented a median AAS of 119 and were mostly discussed on news outlets, Twitter, and Mendeley. Forty-one articles were published in Q1 journals, 24 in Q2 journals, 32 in Q3 journals, and three in Q4 journals. AAS was significantly higher in articles of Q2 journals (median AAS = 398, range = 70-513) than in articles of Q1. A weak reverse correlation existed between AAS and time since publication (r = -.25, p < .05). No correlation was detected between AAS and other publication characteristics or number of citations. CONCLUSIONS: Increased social impact of dental articles is not significantly associated with high citation rates.

[Localised (juvenile) spongiotic hyperplasia of the gingiva; a less common laesion]. / Gelokaliseerde (juveniele) spongiotische hyperplasie van de gingiva: een minder bekende aandoening.

A 49-year-old woman presented with a superficial, ulcerative laesion of approximately 7x3 mm of the marginal labial gingiva of the first upper incisor right. The laesion had returned twice after limited surgical excision. On the basis of a new, extensive excisional biopsy, additional investigation was carried out by the pathologist, which led to a diagnosis of localised (juvenile) spongiotic gingival hyperplasia (LJSGH). The aetiology of LJSGH is still unclear. A typical characteristic is the localised and solitary presence of the laesion. Localised (juvenile) spongiotic hyperplasia of the gingiva is most often seen on the marginal labial gingiva of the maxilla. The laesion can disappear spontaneously, but surgical excision is generally indicated due to the negative cosmetic effect and influence on oral hygiene. The risk of recurrence is high, particularly when the laesion is not radically removed.

Is YouTube useful as a source of information for Sjögren's syndrome?

OBJECTIVES: To quantitatively and qualitatively assess the characteristics of YouTube videos dealing with Sjögren's syndrome. MATERIALS & METHODS: A comprehensive electronic search was performed for 'Sjögren's syndrome' in YouTube. After excluding duplicates, irrelevant videos, and non-English-language domains, 70 videos were included for analysis. Videos were classified as useful, misleading, or personal experience. The overall quality of videos was scored according to the Global Quality Scale (GQS). Useful videos were assessed for reliability and comprehensiveness based on two 5-point scales. Key points of the misleading videos were explored and patients' personal experiences were further investigated. RESULTS: Thirty-six videos (51.4%) were classified as useful, 6 (8.6%) as misleading, and 28 (40%) as patient's personal experience. Independent users tend to upload videos with personal experience, while university channels/professional organizations share useful videos with evidence-based information. Significant difference was observed in GQS among useful, misleading videos, and patient's experiences. The mean reliability, comprehensiveness, and GQS scores of useful videos were 2.5 (s.d.:1.2), 2.6 (s.d.:1.4), and 3.4 (s.d.:1.0), respectively, whereas only six videos (16.7%) were rated as complete vis-à-vis content. The most frequently misleading topics were etiology and treatment. CONCLUSIONS: Specialists should refer their patients to validated e-information resources and actively participate in the development of video-sharing platforms.

Diagnostic properties of ultrasound of major salivary glands in Sjögren's syndrome: a meta-analysis.

OBJECTIVE: To perform a systematic review and meta-analysis on studies examining the properties of ultrasonography of major salivary glands for diagnosing Sjögren's syndrome. MATERIALS AND METHODS: We searched for the literature on eight databases. The quality of included articles was assessed with the QUADAS-2 tool. Publication bias, pooled sensitivity, specificity, diagnostic odds ratio, and 95% confidence intervals (95%CI) were calculated. Meta-regression analysis was performed. RESULTS: We identified 37 studies and 33 ultrasonographic scoring systems. High risk of bias was observed in 'patient selection', 'conduct and interpretation of ultrasound', and 'flow of patients and timing of tests' in 78%, 70%, and 51% of the studies. We included 29 studies in the meta-analysis. Publication bias was highly probable. Pooled sensitivity was 0.69 (95%CI: 0.67-0.71), specificity 0.92 (95%CI: 0.91-0.93), and diagnostic odds ratio 33.89 (95%CI: 20.75-55.35). Significant heterogeneity was detected between studies. Meta-regression analysis showed that studies with high risk of bias in 'conduct and interpretation of ultrasound' and studies evaluating only parenchymal homogeneity had higher log diagnostic odds ratio (1.09 and 2.49, respectively, p < 0.05). CONCLUSIONS: The quality of current studies is low, thus not allowing to judge the likelihood of salivary gland ultrasonography as a reliable and practical tool in diagnosing Sjögren's syndrome.

Internet information on xerostomia: what should patients expect?

OBJECTIVE: To assess the qualitative standards of the information distributed via the Internet regarding xerostomia. MATERIALS AND METHODS: A comprehensive electronic search was performed for 'xerostomia' and 'dry mouth' separately using four search engines. The first 30 results from each search term-engine combination were pooled for analysis. After excluding promotional product sites, discussion groups, video feeds, scientific articles, non-operative sources, sites with denied direct access through password requirement, non-English language domains, and online medical dictionaries, 50 Web pages were evaluated in terms of readability, accessibility, usability, and reliability using recommended research methodology the Flesch Reading Ease Score and the LIDA instrument. Author and information details were also recorded. RESULTS: The results revealed a variable quality of the available Internet information on xerostomia. The Web sites required advanced reading skills, while LIDA scores for accessibility, usability, and reliability ranged from medium to low with average scores extending from 29.1% to 81.3%. CONCLUSIONS: The quality of information about xerostomia among Web sources presents high variability. The existing discrepancy should be alleviated by referring patients to evidence-based education materials on the Internet. Improvement in xerostomia information e-resources will contribute to a more advanced quality in oral health care.
