[Rebound tonometry with sterilized probes]. / Rebound-Tonometrie mit sterilisierten Sonden.

BACKGROUND: Intraoperative measurement of intraocular pressure (IOP) opens up possibilities to investigate the influence of IOP on the stability of the eyeball during the performance of surgical maneuvers. Few techniques have been described, none of which are commercially available. This study investigated the use of sterilized probes for rebound tonometry, which could be used intraoperatively. MATERIAL AND METHODS: Tonometry was performed on 30 eyes using a noncontact tonometer and rebound tonometry with the iCare 100 and iCare 200 (iCare Finland Oy, Vantaa, Finland) in a sitting and in a supine position. When performing rebound tonometry probes from the package were used sequentially with sterilized probes. The comparability of sterilized and nonsterilized probes was investigated using different rebound tonometers and different settings. RESULTS: Measurements on a sitting subject were comparable with sterilized and nonsterilized probes. Statistically significant comparability was also found in a supine position. Measurements with identically sterilized probes on identically positioned subjects were comparable with iCare 100 und iCare 200 (T2 vs. T4, p = 0.003 und T3 vs. T5 p < 0.001). The comparison of measurements of the original probe with the sterilized probe in a sitting and in a supine position were possible with statistical significance (p < 0.005). Measuring with the iCare 200 in a sitting position showed a slightly lower IOP with the sterilized probe with the difference being statistically significant. DISCUSSION: Single autoclaving does not alter the probes' ability to measure IOP. CONCLUSION: The use of probes which have been sterilized according to the regulations for other surgical instruments opens up new possibilities for the intraoperative measurement of IOP. This facilitates the use in scientific studies on surgical techniques. In the postoperative period the use of sterilized probes can reduce the risk of infection.

The causes of nail apparatus pigmentation presenting to a melanoma screening clinic a prospective study.

BACKGROUND: Advanced stage primary cutaneous malignant melanoma (PCMM) has a high mortality. PCMM may affect any area of the skin, including the nail apparatus (malignant melanoma or subungual melanoma). Although nail apparatus malignant melanoma (NAMM) is rare, delayed diagnosis carries a poor prognosis. AIM: The primary aim was to study the range of nail presentations and identify key patterns to aid in differential diagnosis. A secondary aim was to quantify the number of patients requiring surgery, indications for biopsy, and the incidence and characteristics of NAMM. METHODS: This was a prospective study of all referrals with nail apparatus pigmentation to a weekly dedicated melanoma screening clinic over a 6-month period. RESULTS: In total, 2246 patients were included. Of the 38 patients referred with nail pigmentation, 1 (2.6%) was diagnosed with NAMM and involved a fungating amelanotic lesion of the right hallux. The remaining patients were diagnosed with subungual haematoma (20/38; 52.6%), viral wart (2/38; 5.4%), acral fibrokeratoma (1/38; 2.6%), myxoid cyst (3/38; 7.9%), fungal nail infection (4/38; 10.5%), Pseudomonas nail infection (1/38; 2.6%), benign linear pigmentation (2/38, 5.3%), Bowen disease (1/38, 2.6%), psoriatic nail changes (2/38; 5.3%) and matrix malalignment (1/38; 2.6%). Of the eight patients (21.1%) who required surgery, five had a biopsy taken and three underwent surgery. Only 14 cases were followed up by Dermatology. NAMM accounted for 0.7% of all melanomas diagnosed. CONCLUSION: We illustrate the wide range of diagnoses for pigmented nail presentations and highlight the late presentation of advanced disease in a patient presenting with NAMM.

Clinical applications of polytetrafluoroethylene (PTFE) tape in restorative dentistry.

Restorative dental procedures are ever developing; one reason for this can be attributed to newer materials with better handling properties and our ability to manipulate them more effectively. As a result various techniques have been described to aid clinicians in obtaining predictable results in restorative dental procedures. This article aims to review the use of plumber's tape to assist in adhesive, endodontic and implant related dental procedures, when compared to other available materials.

An analysis of inpatient dermatologic consultations at University Hospital Limerick: inadequate infrastructure leads to acute skin failure.

BACKGROUND: Approximately 15-20 % of the general population have skin diseases and it is therefore clear that inpatients can also present with various skin conditions that require dermatology input and in some cases the primary reason for admission to hospital. Inpatient hospital care is more expensive than outpatient care. Recent trends are moving towards outpatient care, as there is huge pressure on hospital bed availability. AIMS: The main aim of this study was to analyse patients referred with dermatological complaints and how soon after admission, were patients assessed by the dermatology team. Most dermatologic work is outpatient based and inpatient workload can be underestimated. METHODS: We retrospectively reviewed our inpatient consultations with a total of 220 consultations (males 113, females 107) between August 2014 and April 2015, to document this significant area of work over an eight-month period. RESULTS: The services requesting consultations were mostly general medicine 45.9 % (101/220), surgery 25.4 % (56/220) and paediatrics 24 % (53/220). Dermatologist's diagnosis was different from the referral team diagnosis in 60 % (132/220) of consults, with prompt inpatient assessment by the dermatologist within 24 h of admission. Most common dermatoses diagnosed included eczema 21.8 % (48/220) and psoriasis 7.3 % (16/220). CONCLUSION: Timely diagnosis and inpatient care has important implications on appropriate treatment, duration of hospital stay and patient outcome.

Restorative complications of orthodontic treatment.

The complications of elective orthodontic treatment are numerous. Patients need to be aware, in advance, of possible problems including resorption, instability, caries, recession and failure to deliver optimal tooth position. The investment of time and resources by all concerned is considerable and if there are adverse outcomes these can be biologically costly in the longer term. A frank and full discussion of the possible problems is necessary following the findings of Montgomery vs. Lanarkshire in 2015.

Balancing the risks and benefits associated with cosmetic dentistry - a joint statement by UK specialist dental societies.

Cosmetic dentistry has become increasingly popular, largely as a result of social trends and increased media coverage. This understandable desire for the alleged 'perfect smile' needs to be tempered with an appropriate awareness of the significant risks associated with invasive cosmetic procedures such as veneers and crowns. Patients need to be properly informed that elective removal of healthy enamel and dentine can result in pulpal injury and poorer periodontal health in the longer term, particularly if they are young. The duty of candour means that they ought to be informed that aggressive reduction of sound tooth tissue is not biologically neutral and results in structural weakening of their teeth. Less invasive procedures such as bleaching on its own or for example, combined with direct resin composite bonding, can satisfy many patient's demands, while still being kinder to teeth and having much better fall-back positions for their future requirements. It is the opinion of the British Endodontic Society, British Society for Restorative Dentistry, Restorative Dentistry UK, Dental Trauma UK, British Society of Prosthodontics and the British Society of Paediatric Dentistry that elective invasive cosmetic dental treatments can result in great benefit to patients, but that some aggressive treatments used to achieve them can produce significant morbidities in teeth which were previously healthy. This is a worrying and growing problem with many ethical, legal and biologic aspects, but many adverse outcomes for patients who request cosmetic dental improvements are preventable by using biologically safer initial approaches to treatment planning and its provision.

A national survey of restorative consultants' treatment provision for head and neck oncology patients.

AIM: To investigate current UK practices in the treatment of head and neck oncology patients by consultants in restorative dentistry. METHOD: A postal questionnaire requesting details of surgical and restorative head and neck oncology care from diagnosis to oral rehabilitation was circulated to all 315 consultants in restorative dentistry in the UK. If a reply was not received within 12 weeks a follow up was sent. RESULTS: One hundred and thirty-two (43%) completed questionnaires were returned. On average 46% of respondents treated head and neck oncology patients, this varied with geographical location. Sixty percent of consultants' weekly workload was less than 25% oncology related, while 13% indicated more than 75%. Of the cohort providing oncology care only 12% thought there was always time for dental screening pre-radiotherapy, furthermore 67% had difficulty liaising with primary care. Within the UK great variety existed between attendance at multidisciplinary team meetings, dental care professional support, and provision of dental implant reconstruction including timing, manufacturer, operator, and funding. CONCLUSION: Significant variation in dental input into head and neck oncology patients' pathways exists, most notably with pre-radiotherapy screening. This study highlights a change in trend for patient rehabilitation with dental implants, and an increase to 52% of restorative dentistry consultants' attendance during a multidisciplinary team meeting.

Peri-implantitis. Part 3: current modes of management.

Peri-implantitis is an inflammatory condition fuelled by the presence of bacteria on the implant surface. As such, in a similar manner to periodontal disease management, the removal of biofilm from the implant surface should result in regression of the disease process. The optimal manner with which this is achieved has yet to be realised. This may be unsurprising due to the relative surface complexity of the implant surface when compared to natural tooth root. Other management strategies include surface decontamination, the removal of implant threads known as implantoplasty, and in severe cases the need to explant. Favourable defects can be reconstructed utilising guided bone regeneration techniques. The current review appraises some of the techniques for the management of peri-implantitis.
