Dental Public Health in Action: Experiences and Responses of Oral Health Care Professionals during the First Wave of the COVID-19 Pandemic in Malta.

Initial impetus for action: Maltese Oral Health Care Professionals (OHCP) experienced changes to clinical practice and redeployment during the COVID-19 pandemic. In the early stages, there were few data on the resultant changes to the provision of dental services or their impact on the wellbeing of dental professionals. Solutions Suggested: Two questionnaires were designed to explore different domains in OHCP working on the frontline of the COVID-19 pandemic as well as in other areas/sectors. The findings were intended to inform guidance documents and to better support the profession. Findings: Anxiety-provoking factors, challenges, and areas of concern of OHCP were identified and practical recommendations to support transitioning to the 'new normal' were presented. OHCP expressed anxiety about contracting COVID-19 from their workplace and passing infection to other family members, friends, or patients. As a result, OHCP expressed the need for better protective clothing, workplace ventilation, and air filtration systems. Future implications: Provision of adequate PPE for OHCP was a priority. New guidelines for dental practice were informed by the experiences of the particpating OHCP. University modules to enhance the resilience of OHCP were among the recommendations to support practitioners.

European Position Paper on Rhinosinusitis and Nasal Polyps 2020.

The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012. The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings. EPOS2020 contains chapters on definitions and classification where we have defined a large number of terms and indicated preferred terms. A new classification of CRS into primary and secondary CRS and further division into localized and diffuse disease, based on anatomic distribution is proposed. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, allergic rhinitis, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. All available evidence for the management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is systematically reviewed and integrated care pathways based on the evidence are proposed. Despite considerable increases in the amount of quality publications in recent years, a large number of practical clinical questions remain. It was agreed that the best way to address these was to conduct a Delphi exercise . The results have been integrated into the respective sections. Last but not least, advice for patients and pharmacists and a new list of research needs are included.

Undergraduate students' evaluation and reflections on a gerodontology programme.

INTRODUCTION: Many societies have observed a steady increase of many older adults living longer due to advancements in health and standard of living. The dental team requires specialised training in gerodontology to better prepare for the future needs of the elderly patients. It is the aim of this study to report the undergraduate students' activities and perspectives on their work experience in a geriatric residence. MATERIALS AND METHODS: An anonymous online questionnaire on the theoretical and practical aspects of training was sent to students in dentistry and dental hygiene (DH) undergraduate courses. Students were also invited to discuss their experiences. Data of clinical treatment performed by the students were collected. The number of clinical hours of student exposure to patients was measured. RESULTS: Completion of the questionnaire was high (90%). Both DH and dentistry students have in excess of 100 hours/y of clinical practice. Overall students rate their experience as a positive one that enriches patients' well-being. However they identify barriers to oral health and experience challenges related to their clinical work and level of competence (Kruskal-Wallis Test P < .05). CONCLUSIONS: study participants were strongly motivated towards the management of frail older adults and cognisant of the barriers and constraints of achieving a reasonable level of oral health. Gerodontology programmes should be adaptable in order to create the appropriate environment and address socio-emotional challenges experienced by students.

European consensus-based (S2k) Guideline on the Management of Herpes Zoster - guided by the European Dermatology Forum (EDF) in cooperation with the European Academy of Dermatology and Venereology (EADV), Part 2: Treatment.

Herpes zoster (HZ, shingles) is a frequent medical condition which may severely impact the quality of life of affected patients. Different therapeutic approaches to treat acute HZ are available. The aim of this European project was the elaboration of a consensus-based guideline on the management of patients who present with HZ, considering different patient populations and different localizations. This interdisciplinary guideline aims at an improvement of the outcomes of the acute HZ management concerning disease duration, acute pain and quality of life of the affected patients and at a reduction in the incidence of postherpetic neuralgia (PHN) and other complications. The guideline development followed a structured and pre-defined process, considering the quality criteria for guidelines development as suggested by the AGREE II instrument. The steering group was responsible for the planning and the organization of the guideline development process (Division of Evidence-Based Medicine, dEBM). The expert panel was nominated by virtue of clinical expertise and/or scientific experience and included experts from the fields of dermatology, virology/infectiology, ophthalmology, otolaryngology, neurology and anaesthesiology. Recommendations for clinical practice were formally consented during the consensus conference, explicitly considering different relevant aspects. The guideline was approved by the commissioning societies after an extensive internal and external review process. In this second part of the guideline, therapeutic interventions have been evaluated. The expert panel formally consented recommendations for the treatment of patients with HZ (antiviral medication, pain management, local therapy), considering various clinical situations. Users of the guideline must carefully check whether the recommendations are appropriate for the context of intended application. In the setting of an international guideline, it is generally important to consider different national approaches and legal circumstances with regard to the regulatory approval, availability and reimbursement of diagnostic and therapeutic interventions.

Serial blood serotonin levels in a randomized controlled trial comparing the efficacy of low-dose amitriptyline, amitriptyline with pindolol and surrogate placebo in patients with chronic tension-type facial pain.

BACKGROUND: Patients often present with chronic facial pain despite normal nasal endoscopy and sinus computerized tomography. Such pain has increasingly been recognized as being of neurological origin with one of the commonest underlying causes being mid-facial segmental tension-type pain (MFP) which is a version of tension headache in the face. Descending serotonergic neuronal projections are known to modulate pain and intra-platelet serotonin levels are an accepted model reflecting central intra-neuronal serotonin. OBJECTIVES: 1.To determine whether low-dose amitriptyline significantly changes whole blood serotonin compared to a surrogate placebo in patients with chronic MFP 2. To determine whether the addition of pindolol, a beta blocker with serotonin receptor blocking properties further alters blood serotonin. METHODOLOGY: Sixty-two patients were randomized to three treatment groups a) amitriptyline , b) amitriptyline with pindolol, and c) loratadine as surrogate placebo. Whole blood serotonin was taken before and after 8 weeks of treatment. Serotonin was also measured in 40 age-matched healthy controls. RESULTS: There was a significant reduction in blood serotonin levels in the amitriptyline with pindolol group. A non-significant reduction was seen in the amitriptyline group, with no change in serotonin levels in the surrogate placebo group. A comparison of change in serotonin with change in pain frequency and intensity scores is presented. Women in the control group had significantly higher serotonin levels than men. Women with tension-type facial pain who failed to respond to treatment had significantly lower blood serotonin than women in the control group. CONCLUSION: When linked to the clinical response this study provides evidence that the serotonergic system is involved in the modulation of chronic MFP. Serotonin levels are sex-dependent and related to treatment response.

A Randomized Controlled Trial comparing the efficacy of low-dose amitriptyline, amitriptyline with pindolol and surrogate placebo in the treatment of chronic tension-type facial pain.

BACKGROUND: Patients often present to otolaryngologists with chronic facial pain, presumed to be of sinus origin despite normal nasal endoscopy and sinus CT. This pain has increasingly been recognized as being of neurological origin with one of the commonest underlying causes being mid-facial segmental tension-type pain (MFP) which is a version of tension-type headache affecting the midface. PRIMARY OUTCOME MEASURES: 1. To determine whether low-dose amitriptyline reduces pain scores compared to surrogate placebo in patients with chronic MFP. 2. To determine whether the addition of pindolol, a beta blocker with serotonin receptor blocking properties hastens onset of action or improves efficacy of amitriptyline. SECONDARY OUTCOME MEASURE: to determine whether amitriptyline or amitriptyline with pindolol significantly reduces analgesic consumption. METHODOLOGY: Sixty two patients were randomized to three treatment groups (a) amitriptyline 10mg daily (b) amitriptyline 10mg daily with pindolol 5mg twice daily and (c) loratadine 10mg daily. Daily pain scores using a facial pain diary were recorded over eight weeks. RESULTS: At 8 weeks, pain frequency and intensity were significantly reduced in patients treated with amitriptyline and in those receiving amitriptyline with pindolol compared to surrogate placebo. Patients on the combination therapy showed significantly improved clinical outcome and significantly reduced analgesic intake compared to those on amitriptyline alone. CONCLUSION: Low dose amitriptyline is effective in the management of MFP and is enhanced by the addition of pindolol.

Long-term follow-up of patients with facial pain in chronic rhinosinusitis--correlation with nasal endoscopy and CT.

AIMS: Commonly attributed to chronic rhinosinusitis (CRS), facial pain is a frequent present-ing complaint in otolaryngology clinics. This study aimed to investigate nasal endoscopy and CT in a cohort of CRS patients presenting primarily with facial pain and to report on their long-term follow-up. SETTING: The setting was a busy otolaryngological practice on a small Mediterranean island. A cohort of 305 consecutive patients with chronic rhinosinusitis refractory to maximal medical therapy was assessed clinically, by nasal endoscopy and coronal sinus CT. The primary presenting symptom in 154 of these individuals was facial pain and this paper studied this particular subgroup of CRS patients. Using the Lund-Mckay scoring system, a CT positive for sinusitis was set at 2 or higher. A score of 0 or I was considered negative for sinusitis. The findings in CT positive and CT negative patients were compared. RESULTS: The CT in 61 (40%) patients with facial pain scored positive while 93 (60%) patients had a negative CT. Patients with facial pain as the presenting symptom in rhinosinusitis were significantly less likely to score positive for sinusitis on CT (chi squared test, p<0.0001). CT positive patients were significantly more likely to have pus or nasal polyps (chi squared test, p<0.0001) on nasal endoscopy than CT negative patients. Only 36% of patients with facial pain and other sinusitis symptoms had chronic rhinosinusitis as confirmed by CT and presence of pus or polyps on nasal endoscopy. Patients with positive CT were significantly more likely to be treated surgically while those with a negative CT were significantly more likely to be treated by medication (chi squared test, p<0.0001). CONCLUSION: Patients were followed up for a mean of two years and their outcomes analysed. The outcome for conservative treatment in CT negative patients (68% good or improved) was not as good as the outcome for surgical treatment in CT positive patients (87% good or improved).

Chronic sinusitis in Malta--correlation between symptoms and CT scan.

INTRODUCTION: The diagnosis of chronic rhinosinusitis (CRS) is clinical as it is based on patient symptoms. Sinus CT has been used as an objective measure of CRS with varying degrees of success and correlation to patient symptoms. AIMS: This study aimed to investigate the relationship between patient symptoms, nasal endoscopic findings and CT in a small Mediterranean island community. A cohort of 305 consecutive patients with symptoms of CRS, that persisted despite maximal medical therapy, was evaluated by medical history, clinical examination and nasal endoscopy followed by sinus CT. Scans scoring 2 or higher on the Lund-Mckay scoring system were classified as positive for sinusitis while those scoring 0 or 1 were classified as negative for sinusitis. SETTING: The setting of this study was a busy otolaryngological practice on a small Mediterranean island using a computerised database. RESULTS: In total, 172 patients (56%) had positive and 133 (44%) had negative CT scans. Males with CRS were significantly more likely to have a positive CT (chi squared test, p=0.0005). Postnasal drip/rhinorrhoea, nasal obstruction and hyposmia as primary symptoms were significantly more likely to be associated with a positive CT (chi squared test p=0.0001). Patients presenting with facial pain as the primary symptom were significantly more likely to have a negative CT (chi squared test, p=0.0001). Middle meatal pus or nasal polyps on nasal endoscopy were significantly more likely to be associated with a subsequently positive CT (chi squared test, p<0.0001). Mucosal oedema of the middle meatus was a non-specific finding. CT positive patients were more likely to be treated surgically while CT negative patients were more likely to be treated with medication (chi squared test, p=0.0001). CONCLUSION: Patients were followed up for a mean of 2 years. Overall, there was a good or improved outcome in 81% of patients. Those with a positive CT did significantly well with surgical treatment.

Smoking and middle ear ciliary beat frequency in otitis media with effusion.

The middle ear mucociliary system has been shown to play an important role in clearing middle ear effusions. There is conflicting epidemiological evidence, however, as to whether exposure to tobacco smoke plays a significant role in persistence of middle ear effusion in patients with otherwise normal mucociliary function. Samples of middle ear mucosa from 33 patients with persistent otitis media with effusion (OME) were taken at myringotomy, together with corresponding nasal brushings. The aim of this study was to observe the mean ear ciliary beat frequency (CBF) and to compare it with nasal ciliary activity. Nasal brushings were collected from 33 age and sex matched non-smoking controls with no history of nasal atopy or topical nasal treatment. Ear CBF in OME was significantly reduced in comparison to paired nasal samples (p < 0.001). Ear CBF in adult OME patients who smoked or in children who were passive smokers was significantly less than in patients who were not exposed to cigarette smoke (p < 0.01). This study indicates that impaired ciliary function due to tobacco smoke exposure is an aetiological factor in persistent OME.

Surface morphology of middle ear epithelium in chronic ear disease.

The ultrastructural details of normal middle ear mucosa have been reported in detail in the literature. This study was aimed at investigating the superficial structure of middle ear epithelium with the scanning electron microscope in patients with persistent otitis media with effusion (OME) and chronic suppurative otitis media (CSOM), especially in the light of the authors' recent findings regarding decreased ciliary beat frequency (CBF) in patients exposed to tobacco smoke. Mucosal biopsies were taken from the anterior mesotympanum in four patients with OME and another four patients with CSOM. There was no significant abnormality of cellular surface structure in patients with chronic middle ear disease. Furthermore, no significant difference was observed between smoke exposed and nonsmoke exposed patients. It is concluded that the effect of tobacco smoke on CBF is functional and not related to any anatomical abnormality observed by scanning electron microscopy (SEM).

Is 'sinus' pain really sinusitis?

So-called 'sinus pain' is a common complaint in GP and ear, nose and throat clinics, and patients often receive treatment with antibiotics and decongestants. Recent evidence suggests that facial pain may not be related to the sinuses at all and that doctors may have to rethink their prescribing strategy.

Prospective three-year follow up of a cohort study of 240 patients with chronic facial pain.

BACKGROUND: Patients often present with facial pain ascribed to sinusitis, despite normal nasal endoscopy and sinus computed tomography. Facial pain is increasingly recognised to be of neurological origin. METHOD: A cohort of 240 patients with chronic facial pain was followed up for 36 months at an otolaryngological practice in Malta. The types of facial pain were classified according to International Headache Classification criteria. The body mass index, occupation and educational level of patients were compared with the general population. RESULTS: Tension-type mid-facial pain and facial migraine without aura were the most common types of chronic facial pain. The sites of pain, symptoms, treatment and outcomes for these principal pain types are discussed. Patients with mid-facial pain were treated with low-dose amitriptyline for eight weeks. After three years, nearly half of the patients were symptom free, and in a third the pain changed from being chronic to being episodic. The treatment of patients with facial migraine was more varied but the length of time until recurrence of pain was similar. CONCLUSION: The most effective long-term treatments for tension-type mid-facial pain and facial migraine were low-dose amitriptyline and low-dose amitriptyline and triptans, respectively.

Hyponatraemia after transurethral resection of the prostate.

Transurethral resection (TUR) syndrome is a complication of transurethral resection of the prostate characterized by bradycardia, hypotension and postoperative confusional state, which is generally attributed to hyponatraemia occurring during or immediately after operation. In a prospective study of 100 consecutive patients undergoing transurethral resection of the prostate, changes in serum sodium were estimated before and after operation and correlated with various parameters including weight of prostate resected, volume of irrigant fluid and resection time. Seven patients showed a significant drop (greater than 10 mmol/litre) in serum sodium: two of these had the clinical features of TUR syndrome and one of them died. The pathogenesis and management of this syndrome are discussed.

Patient compliance with short-term topical aural antibiotic therapy.

Little is known about patient compliance with topical aural antibiotic regimens. The compliance of 50 patients with unilateral otitis externa attending an otolaryngology clinic was studied by comparing the weight of dispensed topical ear preparations before and after completion of a 7-day-course of treatment. A standard was obtained from controlled administration of the preparation under laboratory conditions and the performance of different delivery systems evaluated. Thirty-seven patients re-attended for review with their medication. A total of 34 of 50 patients entering the study (70%) satisfied conventional criteria for compliance. However, over-use of preparations was common and stricter criteria are proposed and applied. Compliance was significantly increased when someone other than the patient administered the preparation.

A prospective study of otitis externa.

A prospective study of otitis externa in the district of South Bedfordshire was undertaken between October 1990 and January 1991. Patients were referred untreated by general practitioners; self-referred patients with external otitis were also included. A detailed history was taken, the severity of the condition assessed, aural toilet performed, bacteriology swabs taken and the patient treated according to department protocol. 48 patients were included in the study; a similar number of age and sex-matched controls without otitis externa were randomly selected from the ENT outpatient clinics for comparison. Regular swimming emerged as a significant factor in the aetiology of otitis externa. The commonest organism cultured was Pseudomonas aeruginosa and this accounted for the most severe cases seen.

The role of atopy in Maltese patients with chronic rhinitis.

The global prevalence of allergic rhinitis has been on the increase and recent clinical experience in Malta has shown a similar trend. The aim of this study was to investigate the role of atopy in 415 patients presenting with rhinitis of at least 3 months duration, and to identify the common allergens responsible. Presenting clinical features, past and family history of seasonal allergic symptoms, exposure to cigarette smoking, pet ownership and occupation were analysed. All patients were skin tested for common allergens. Fifty-five per cent of patients were atopic, the main allergens responsible being house dust mite, cat dander and grass pollen. Rhinorrhoea and sneezing were significantly more common in atopic patients, who were more likely to have a past history and family history of seasonal asthma, eczema or rhinoconjunctivitis. Skin test-negative patients with idiopathic rhinitis were mostly females and tended to present a decade later. Differentiation between atopic and idiopathic chronic rhinitis may be helpful in the clinical setting in order to help predict response to treatment.

Age, smoking and nasal ciliary beat frequency.

The nasal ciliary beat frequency of 120 individuals in a British urban population was determined from nasal brushings. These individuals formed part of a previous study which looked at nasal and middle ear ciliary beat frequency in 60 patients with middle ear disease and compared it to nasal ciliary beat frequency in 60 matched controls. The present study intended to investigate any changes in nasal ciliary beat frequency with age. Comparison was also made between patients who were habitually exposed to tobacco smoke and non-exposed individuals. Nasal brushings were taken from the inferior turbinate using a cytology brush and the beat frequency was determined using a computerized photometric technique. In the population studied ages ranged from 2 to 69 years (mean 10.9 +/- 19.7 years). The mean beat frequency of 120 individuals was 11.5 +/- 2.5 Hz (SD), range 5.5-19.2 Hz. There was no particular trend observed with regards to beat frequency and advancing age. Nasal ciliary beat frequency in tobacco smoke-exposed patients (whether active or passive smokers) was significantly less than that in non-smoke exposed controls (P = 0.02, Student's t-test).

The effects of in vitro cotitine on nasal ciliary beat frequency.

Cotitine is one of the main metabolites of nicotine. It is stable and in vivo has a relatively long circulating half life. Nasal ciliated cells from non-smoking individuals were exposed in vitro to solutions of cotitine corresponding to serum levels in active and passive smokers. Ciliary beat frequency was measured by a computerized photometric technique. There was a significant drop in ciliary beat frequency compared with control ciliated cells in phosphate buffered saline. It is concluded that cotitine in active or passive smoking has a marked effect on ciliary function. It may be a factor leading to diminished mucociliary clearance and persistent middle ear effusion.

Nasal and middle ear ciliary beat frequency in chronic suppurative otitis media.

The middle ear mucociliary system has been shown to have an important function in the clearance of effusions. Little is known, however, about its role in chronic suppurative otitis media (CSOM). The ciliary beat frequencies of middle ear mucosal biopsies and nasal brushings of 27 patients with CSOM were analysed using a computerized photometric technique. The ciliary beat frequency in the middle ear mucosa was significantly less than that in nasal mucosa. Frequency in ears of smoking patients was significantly lower compared with non-smoking patients. Nasal brushings were taken from 27 otherwise healthy age and sex-matched non-smoking controls and the ciliary beat frequency was very similar to nasal samples from patients with CSOM. Ear controls were obtained from otosclerotic patients undergoing tympanotomy and the beat frequency was significantly higher than in the ear of patients with CSOM. It is concluded that middle ear ciliary function is significantly reduced in CSOM, particularly in patients who smoke.
