RESUMO

PURPOSE: To determine the changes in keratometry measurements and refraction in patients having the thermo-mechanical periorbital skin treatment, Tixel®, to treat dry eye disease (DED). METHODS: A multi-centre, prospective, non-masked study was conducted. DED patients were recruited in 3 international centres and were evaluated in 5 visits separated by an interval of 2 weeks except for the last visit which took place after 18 weeks from visit 1. The same clinical examination was performed at all visits: OSDI questionnaire, tear stability, keratometry, best corrected visual acuity and refraction. Tixel® treatment was applied at the first 3 visits. RESULTS: 89 participants (24 males/65 females; mean age: 55.0 ± 14.2 years) were included: 20 presented moderate DED symptoms and 69 severe DED symptoms. Significant differences were found for the spherocylindrical refraction (vector analysis) between visit 1 and visits 2 and 3. Following cumulative analysis, 11.86 % and 16.94 % of participants had more than 0.5 dioptre (D) change in mean keratometry and keratometric astigmatism, respectively, at 3 months post-treatment. A total of 5.40 % had a sphere and cylinder change greater than 0.50D and 16.21 % had the axis changed more than 10 degrees (vector analysis). These changes were particularly significant in patients with severe DED symptoms. CONCLUSIONS: Keratometry readings and refraction can change following thermo-mechanical skin treatment for DED, especially in those patients with severe DED symptoms. This should be considered as potential errors in intraocular lens calculations may be induced.

RESUMO

Since its introduction, optical coherence tomography (OCT) has revolutionized the field of ophthalmology and has now become an indispensable, noninvasive tool in daily practice. Most ophthalmologists are familiar with its use in the assessment and monitoring of retinal and optic nerve diseases. However, it also has important applications in the assessment of anterior segment structures, including the cornea, conjunctiva, sclera, anterior chamber, and iris, and has the potential to transform the clinical examination of these structures. In this review, we aim to provide a comprehensive overview of the potential clinical utility of anterior segment OCT (AS-OCT) for a wide range of anterior segment pathologies, such as conjunctival neoplasia, pterygium, scleritis, keratoconus, corneal dystrophies, and infectious/noninfectious keratitis. In addition, the clinical applications of AS-OCT (including epithelial mapping) in preoperative planning and postoperative monitoring for corneal and refractive surgeries are discussed.

RESUMO

Keratoconus is the most common corneal ectatic disorder. It is characterized by progressive corneal thinning with resultant irregular astigmatism and myopia. Its prevalence has been estimated at 1:375 to 1:2,000 people globally, with a considerably higher rate in the younger populations. Over the past two decades, there was a paradigm shift in the management of keratoconus. The treatment has expanded significantly from conservative management (e.g., spectacles and contact lenses wear) and penetrating keratoplasty to many other therapeutic and refractive modalities, including corneal cross-linking (with various protocols/techniques), combined CXL-keratorefractive surgeries, intracorneal ring segments, anterior lamellar keratoplasty, and more recently, Bowman's layer transplantation, stromal keratophakia, and stromal regeneration. Several recent large genome-wide association studies (GWAS) have identified important genetic mutations relevant to keratoconus, facilitating the development of potential gene therapy targeting keratoconus and halting the disease progression. In addition, attempts have been made to leverage the power of artificial intelligence-assisted algorithms in enabling earlier detection and progression prediction in keratoconus. In this review, we provide a comprehensive overview of the current and emerging treatment of keratoconus and propose a treatment algorithm for systematically guiding the management of this common clinical entity.

RESUMO

This study aims to describe how in-vivo confocal microscopy (ICVM) results improved diagnosis and treatment in three patients with complex corneal disorders at a single institution. Case one was a 36-year-old woman contact lens wearer referred to the hospital eye service (HES) by her community optician for a suspected corneal ulcer in her left eye. The case demonstrated that where laboratory cell culture was inconclusive, IVCM imaging improved diagnosis and more importantly adjusted the initial treatment till the complete resolution of the case. Case two was a shared-care 66-year-old keratoconus patient under a complex immunosuppression regime who had developed a recent series of post-surgical complications of fungal origin and was experiencing eye pain. IVCM was able to differentiate between an immune-mediated response and fungal keratitis and guide the clinicians towards an optimized treatment. Case three was a long-standing dry eye disease in a 64-year-old woman diagnosed with primary Sjögren's syndrome where previous treatments failed to improve her symptomatology. IVCM was crucial for prescribing allogeneic serum eyedrops by anticipating early immune changes in the sub-basal corneal nerve plexus. In-vivo confocal microscopy can be an essential non-invasive imaging technique for improving clinicians' diagnostic precision by adding a layer of certainty that other techniques may lack. Additionally, IVCM allows adjustment of the treatment accordingly, by instantly following any pathologic changes at the cellular level.

RESUMO

PURPOSE: To determine the effects of a thermo-mechanical action-based peri-orbital fractional skin treatment (Tixel®) on dry eye disease. METHODS: This prospective, controlled, open labelled study was conducted at two study centres: Midland Eye, Solihull, UK, and Vallmedic Vision, Andorra. Participants were screened at the baseline visit (visit-1), received three Tixel® treatments at 2-weeks intervals including further assessment (visits 2, 3 and 4). Participants were followed up for three months post-treatment (visit 5). Vision, intraocular pressure (IOP), dry eye symptomatology were assessed, including the Ocular Surface Disease Index (OSDI) questionnaire, non-invasive tear break-up time (NIBUT) and tear osmolarity as well as detailed ophthalmic assessments. RESULTS: Seventy-four participants (41 in Birmingham and 33 in Andorra) with periorbital wrinkles and moderate to severe dry eye disease (DED) were enrolled. The mean age was 59.3 ± 13.3 years and 57 were females. No adverse events, no change in vision (p = 0.310) or IOP (p = 0.419) were observed. Tixel treatment was associated with clinically and statistically significant improvement in the DED symptoms, which was supported by a reduction of 21.40 ± 15.08 (P < 0.001) of the OSDI index. Non-invasive tear break-up time improved by 2.10 ± 0.91 s (p < 0.001) in the Birmingham cohort and 6.60 ± 2.13 s (p < 0.001) in the Andorra cohort. Tear osmolarity reduced from 299.8 ± 13.3 mOsm/L to 298.8 ± 15.6 mOsm/L following the Tixel treatment (p = 0.271). CONCLUSIONS: Thermo-mechanical action-based peri-orbital fractional skin treatment Tixel® could be an attractive, safe and effective treatment for DED. This treatment is associated with high clinical and statistically significant improvement in DED signs and symptoms with no adverse events.

RESUMO

Vernal keratoconjunctivitis (VKC) is a form of ocular allergy primarily affecting children. Considered a rare disease in Europe, its prevalence varies by geographic region and is poorly studied in the United Kingdom. There is considerable national variation in the management of VKC within the United Kingdom, risking misdiagnosis and delays to treatment for some children. This can significantly impact their quality of life, with the potential for lasting negative consequences. Based on discussions between experienced clinicians from six large centers across the United Kingdom, this article describes best practice recommendations for United Kingdom settings, including principles for diagnosis, referral, initial and long-term management, and supportive care. Recommendations include guidance on referral timing, which should depend on VKC severity, and a stepwise approach to treatment. Joint management by primary care and secondary care is recommended and the importance of supportive care, including emotional support and outreach to schools, is highlighted. Because frequent flareups are common in VKC, it is essential that families have access to the information they need to manage the disease and routes to access rapid care if needed. A thorough understanding of the nature of VKC, its triggers, and how best to manage it, by both patients and their families, is critical to ensuring appropriate management and to improving patient outcomes.

RESUMO

OBJECTIVE: To report outcomes of tacrolimus immunosuppression after penetrating keratoplasty (PK) in very young children. METHODS: Retrospective, consecutive, cohort study of children undergoing PK at a tertiary children's hospital between 2005 and 2016. Oral tacrolimus immunosuppression was given for 2 years, followed by topical tacrolimus. RESULTS: Fourteen children (20 eyes) had 24 PKs; nineteen eyes had primary PKs, five eyes had repeat PKs. Mean age at primary graft was 95 days (3.1 months) for anterior segment dysgenesis (ASD), 430 days (14.3 months) for non-ASD children. Eleven children (15 eyes) had ASD. Three children (five eyes) had non-ASD: two children (three eyes) had glaucoma-related corneal opacity and one child (two eyes) had congenital hereditary endothelial dystrophy (CHED). One-year rejection-free survival rates following primary PK was 80% for ASD (n = 15) and 100% for non-ASD (n = 4). At final review, 5/15 of primary grafts for ASD were clear. 10/15 failed after a mean of 19 months, specifically attributable to infection (n = 2), rejection (n = 2) and glaucoma (n = 2). 4/4 primary non-ASD grafts are clear at final review (mean follow-up = 77 months). All repeat grafts (n = 5), failed after a mean of 38.25 months. Considering all grafts, 15/24 (62.5%) failed: 5/15 due to infection, 2/15 due to rejection, 8/15 due to glaucoma, phthisis, perforation or vascularised with no rejection. At last review (mean = 58.1 months, range 28-84), overall cohort survival is 37.5%. Final visual acuities range between 0.86 and 2.4 LogMAR. CONCLUSION: We compare our results to published literature: 1-year graft survival was higher than previously reported, with lower failure due to rejection. Overall infection rates did not increase, however, proportionally, severe infections were higher. Overall graft survival is at least comparable to reported literature.

RESUMO

Keratoconus is emerging as a new subspecialty in ophthalmology. The literature is booming with publications on the topic as we have better understanding of the pathophysiology, treatment and prognosis of the disease over the past two decades. Advances in diagnostic tools as well as genuine increase in prevalence have shifted perspective of the disease from being a rare one. Early diagnosis is of public health interest as early treatment arrests progression. With the view to encourage research, increase awareness and to reflect the evolution of knowledge related to keratoconus, the European Journal of Ophthalmology has dedicate a special section on keratoconus in its journal.

RESUMO

PURPOSE: To describe a simple alternative surgical approach to treat patients with Meibomian gland inversion (MGI; posterior migration of the Meibomian gland orifices) in the upper eyelid, secondary to cicatricial Meibomian gland dysfunction (MGD) not responding to maximal medical management. METHODS: This was a retrospective, noncomparative, interventional case series of all patients with MGI not responding to conservative MGD treatment who underwent anterior lamellar repositioning through a skin crease incision with or without Blepharoplasty, between July 2017 and July 2019. RESULTS: Eleven eyes of 7 patients were included in the study. All patients had a diagnosis of MGD with MGI and had been treated on average for 32 months with intensive medical therapy. Treatment included lubricants, topical ciclosporin 0.1%, topical steroids, and doxycycline. Despite intensive treatment, these patients remained symptomatic with persistent superior ocular surface staining. Following surgery, on average, the patients were followed for 23 months. Ten eyes (91%) had improvement of symptoms and superior ocular surface staining. All patients (100%) demonstrated improvement in the anatomical eversion of the eyelid margin and Meibomian gland orifice. CONCLUSION: A simple upper eyelid everting surgery with anterior lamellar repositioning can be effective in managing patients with MGI giving them symptomatic relief when all medical treatment fail. To the best of the authors' knowledge, this is the first case series describing this simple surgical technique in the management of this subgroup of patients.

RESUMO

OBJECTIVE: Eating self-efficacy behavior is an important predictor of successful lifestyle intervention. This secondary analysis evaluated the changes in eating self-efficacy behavior in patients with type 2 diabetes (T2D) and overweight/obesity following structured lifestyle intervention based on the Malaysian customized transcultural Diabetes Nutrition Algorithm (tDNA). METHODS: Patients with T2D and overweight/obesity (n = 230) were randomized either into the tDNA group which included a structured low-calorie meal plan using normal foods, incorporation of diabetes-specific meal replacements, and an exercise prescription or usual T2D care (UC) for 6 months. Patients in the tDNA group also received either counseling with motivational interviewing (tDNA-MI) or conventional counseling (tDNA-CC). The UC group received standard dietary and exercise advice using conventional counseling. Eating self-efficacy was assessed using a locally validated Weight Efficacy Lifestyle (WEL) questionnaire. All patients were followed up for additional 6 months' post-intervention. RESULTS: There was a significant change in WEL scores with intervention over one-year [Group X Time effect: F = 51.4, df = (3.4, 318.7), p<0.001]. Compared to baseline, WEL scores improved in both the tDNA groups with significantly higher improvement in the tDNA-MI group compared to the tDNA-CC and UC groups at 6 months (tDNA-MI: 25.4±2.1 vs. tDNA-CC: 12.9±2.8 vs. UC: -6.9±1.9, p<0.001). At 12 months' follow-up, both the tDNA groups maintained improvement in the WEL scores, with significantly higher scores in the tDNA-MI group than tDNA-CC group, and the UC group had decreased WEL scores (tDNA-MI: 28.9±3.1 vs. tDNA-CC: 11.6±3.6 vs. UC: -13.2±2.1, p<0.001). Patients in the tDNA-MI group with greater weight loss and hemoglobin A1C reduction also had a higher eating self-efficacy, with a similar trend observed in comparative groups. CONCLUSION: Eating self-efficacy improved in patients with T2D and overweight/obesity who maintained their weight loss and glycemic control following a structured lifestyle intervention based on the Malaysian customized tDNA and the improvement was further enhanced with motivational interviewing. CLINICAL TRIAL: This randomized clinical trial was registered under National Medical Research Registry, Ministry of Health Malaysia with registration number: NMRR-14-1042-19455 and also under ClinicalTrials.gov with registration number: NCT03881540.

RESUMO

OBJECTIVE: Pachymetry plays a crucial role in the diagnosis and management of glaucoma and corneal diseases. There have been several outbreaks of epidemic ocular infections in ophthalmology clinics worldwide with reports of viral, parasitic, and prion disease. Contact pachymetry is a possible vehicle of transmission due to its risk of contamination. We aim to identify the types of pachymetry used and methods employed for cleaning and disinfection in eye units throughout the United Kingdom. METHODS: A telephone survey was carried out, and a senior nurse or sister questioned based on the proforma created. A follow-up email was sent to units that did not respond with the questionnaire attached. RESULTS: Of 109 responses, 10 eye units were unaware of the device name and 4 were unaware of the cleaning method used. Overall, 69/105 (66%) were cleaned with some form of alcohol wipe between patients, 12/105 (11%) used presept solution to soak the pachymetry head mainly 5 to 10 minutes, with 2 units soaking for 20 to 30 minutes. Milton solution was used by 4 units (4%) (10 s to 10 min). Three used a hydrogen peroxide solution for 10 minutes (3%). Three (3%) used an alcohol solution. Fifteen (14%) units used some chlorine-based solution (actichlor/chloraprep) for 5 to 10 minutes. Two (2%) units combined an alcohol-based wipe with solution to soak afterward. CONCLUSIONS: There is a large variation in methods and duration of tip disinfection with only a few units following the Royal College of Ophthalmologists (RCOphth) guidelines on pachymeter disinfection. The majority of eye units use alcohol/chlorine-based wipes for cleaning the pachymetry heads which is against the current recommended guidelines. The average immersion time when solutions were used was 5 to 10 minutes.

RESUMO

PURPOSE OF THE STUDY: To report an observational study of Acanthamoeba Keratitis (AK) in University Hospital Coventry & Warwickshire (UHCW), Coventry, UK and determine risk factors, outcomes as well as incidence rates. METHODS: A retrospective analysis was done of consecutive patients who were treated for AK by the corneal service at UHCW from January 2017 to January 2018. Cases were identified from 2 sources; the department of microbiology and the hospital pharmacy. Patient data was collected by 3 of the authors using both paper and electronic medical records. Information was also gathered over the telephone using a predefined questionnaire. The primary endpoint used for assessing duration of disease was time to resolution after the initial diagnosis. RESULTS: 9 eyes were identified over the 12-month period, a drastic increase from previous years. All were contact lens (CL) wearers and 3 used daily disposable CL's. 8 out of 9 patients had an improvement in best corrected visual acuity (BCVA) which was consistent with their baseline levels pre-infection. The average length of treatment was 107.25 days for the 8 resolved cases. 1 case is still having ongoing treatment. No case has required surgical treatment. Several patients admitted to exposing their CL to unsterile water either via swimming, showering or tap water. All patients had purchased their lenses from contact lens practitioners. CONCLUSION: Overall, our study shows excellent outcomes. Almost all patients had resolution of symptoms with medical treatment and an improvement in visual acuity. Several contributing factors have aided us in achieving this including early diagnosis, a robust treatment protocol and diagnostic modalities such as Polymer Chain Reaction (PCR) and Confocal Microscopy (CFM). However, the increased incidence compared to previous years is a worrying trend and there will be an ongoing analysis looking at patterns of incidence in the future.

RESUMO

BACKGROUND: Congenital bleeding disorders can cause obstetric haemorrhage during pregnancy, labour and following delivery. Desmopressin acetate (DDAVP) is found to be an effective drug which can reduce the risk of haemorrhage and can also stop bleeding in certain congenital bleeding disorders. Its use in pregnancy has been controversial. Hence beneficial and adverse effects of DDAVP in these groups of pregnant women should be evaluated.This is an update of a Cochrane Review first published in 2013 and updated in 2015. OBJECTIVES: To evaluate the efficacy and safety of DDAVP in preventing and treating acute bleeding in pregnant women with bleeding disorders. SEARCH METHODS: We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coaguopathies Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant and abstract books of conferences proceedings. We also searched several clinical trial registries and grey literature (27 August 2017).Date of most recent search of the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coaguopathies Trials Register: 01 October 2018. SELECTION CRITERIA: Randomised and quasi-randomised controlled trials investigating the efficacy of DDAVP versus tranexamic acid or factor VIII or rFactor VII or fresh frozen plasma in preventing and treating congenital bleeding disorders during pregnancy were eligible. DATA COLLECTION AND ANALYSIS: No trials matching the selection criteria were eligible for inclusion. MAIN RESULTS: No trials matching the selection criteria were eligible for inclusion. AUTHORS' CONCLUSIONS: No randomised controlled trials were identified investigating the relative effectiveness of DDAVP for bleeding during pregnancy in women with congenital bleeding disorders. In the absence of high-quality evidence, clinicians need to use their clinical judgement and lower level evidence (e.g. from observational trials) to decide whether or not to treat women with congenital bleeding disorders with DDAVP.Given the ethical considerations, future randomised controlled trials are unlikely. However, other high-quality controlled studies (such as risk allocation designs, sequential design, parallel cohort design) to investigate the risks and benefits of using DDAVP in this population are needed.Given that there are unlikely to be any trials published in this area, this review will no longer be regularly updated.

RESUMO

BACKGROUND: Acute sinusitis is a common reason for primary care encounters. It causes significant symptoms including facial pain, congested nose, headache, thick nasal mucus, fever, and cough and often results in time off work or school. Sinusitis treatment focuses on eliminating causative factors and controlling the inflammatory and infectious components. The frozen, dried, natural fluid extract of the Cyclamen europaeum plant delivered intranasally is thought to have beneficial effects in relieving congestion by facilitating nasal drainage, and has an anti-inflammatory effect. OBJECTIVES: To assess the effectiveness of topical intranasal Cyclamen europaeum extract on clinical response in adults and children with acute sinusitis. SEARCH METHODS: We searched CENTRAL, which includes the Cochrane Acute Respiratory Infections Group's Specialised Register, MEDLINE, Embase, and trials registers (ClinicalTrials.gov; WHO ICTRP) in January 2018. We also searched the reference lists of included studies and review literature for further relevant studies and contacted trial authors for additional information. SELECTION CRITERIA: Randomised controlled trials comparing Cyclamen europaeum extract administered intranasally to placebo, antibiotics, intranasal corticosteroids, or no treatment in adults or children, or both, with acute sinusitis. Acute sinusitis was defined by clinical diagnosis and confirmed by nasal endoscopy or by radiological evidence. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed trial quality. We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We included two randomised controlled trials that involved a total of 147 adult outpatients with acute sinusitis confirmed by radiology or nasal endoscopy who were assigned to Cyclamen europaeum nasal spray or placebo study arms for up to 15 days. The risk of selection and detection bias was unclear, as allocation concealment and blinding of outcome assessors were not reported in either study. Attrition was high (60%) in one study, although dropouts were balanced between study arms.Neither study reported our two primary outcomes: proportion of participants whose symptoms resolved or improved at 14 days and 30 days. No serious adverse events or complications related to treatment were reported; however, more mild adverse events such as nasal and throat irritation, mild epistaxis, and sneezing occurred in Cyclamen europaeum group participants (50%) compared to placebo group participants (24%) (risk ratio 2.11, 95% confidence interval 1.35 to 3.29); moderate-quality evidence. AUTHORS' CONCLUSIONS: The effectiveness of Cyclamen europaeum for people with acute sinusitis is unknown. Although no serious side effects were observed, 50% of participants who received Cyclamen europaeum reported adverse events compared with 24% of those who received placebo.

RESUMO

OBJECTIVE: Trans-cultural diabetes nutrition algorithm (tDNA) was created by international task force and culturally customized for Malaysian population. This study was designed to evaluate its effectiveness versus usual diabetes care in primary care settings. RESEARCH DESIGN AND METHODS: We randomized 230 patients with overweight/obesity, type 2 diabetes, and glycated hemoglobin (A1c) 7%-11% to receive usual care (UC) or UC with tDNA for 6 months. The tDNA intervention consisted of structured low-calorie meal plan, diabetes-specific meal replacements, and increased physical activity. Participants were counseled either through motivational interviewing (tDNA-MI) or conventional counseling (tDNA-CC). The UC group received standard dietary and exercise advice through conventional counseling. All patients were followed for another 6 months after intervention. RESULTS: At 6 months, A1c decreased significantly in tDNA-MI (-1.1±0.1%, p<0.001) and tDNA-CC (-0.5±0.1%, p=0.001) but not in UC (-0.2±0.1%, p=NS). Body weight decreased significantly in tDNA-MI (-6.9±1.3 kg, p<0.001) and tDNA-CC (-5.3±1.2 kg, p<0.001) but not in UC (-0.8±0.5 kg, p=NS). tDNA-MI patients had significantly lower fasting plasma glucose (tDNA-MI: -1.1±0.3 mmol/L, p<0.001; tDNA-CC: -0.6±0.3 mmol/L, p=NS; UC: 0.1±0.3 mmol/L, p=NS) and systolic blood pressure (tDNA-MI: -9±2 mm Hg, p<0.001; tDNA-CC: -9±2 mm Hg, p=0.001; UC: -1±2 mm Hg, p=NS). At 1 year, tDNA-MI patients maintained significant reduction in A1c (tDNA-MI: -0.5±0.2%, p=0.006 vs tDNA-CC: 0.1±0.2%, p=NS and UC: 0.02±0.01%, p=NS) and significant weight loss (tDNA-MI: -5.8±1.3 kg, p<0.001 vs tDNA-CC: -3.3±1.2 kg, p=NS and UC: 0.5±0.6 kg, p=NS). CONCLUSIONS: Structured lifestyle intervention through culturally adapted nutrition algorithm and motivational interviewing significantly improved diabetes control and body weight in primary care setting.

RESUMO

OBJECTIVES: Flipped classroom (FC) is a pedagogical model to engage students in learning process by replacing the didactic lectures. Using technology, lectures are moved out of the classroom and delivered online as means to provide interaction and collaboration. Poll Everywhere is an audience response system (ARS) which can be used in an FC to make the activities more interesting, engaging, and interactive. This study aims to study the perception of undergraduate pharmacy students on FC activity using Poll Everywhere ARS and to study the effectiveness of FC activity as a teaching-learning tool for delivering complementary medicine module in the undergraduate pharmacy program. MATERIALS AND METHODS: In this nonrandomized trial on interrupted time series study, flipped class was conducted on group of 112 students of bachelor of pharmacy semester V. The topic selected was popular herbal remedies of the complementary medicine module. Flipped class was conducted with audio and video presentation in the form of a quiz using ten one-best-answer type of multiple-choice questions covering the learning objectives. Audience response was captured using web-based interaction with Poll Everywhere. Feedback was obtained from participants at the end of FC activity and debriefing was done. RESULTS: Randomly selected 112 complete responses were included in the final analysis. There were 47 (42%) male and 65 (58%) female respondents. The overall Cronbach's alpha of feedback questionnaire was 0.912. The central tendencies and dispersions of items in the questionnaire indicated the effectiveness of FC. The low or middle achievers of quiz session (pretest) during the FC activity were three times (95% confidence interval [CI] = 1.1-8.9) at the risk of providing neutral or negative feedback than high achievers (P = 0.040). Those who gave neutral or negative feedback on FC activity were 3.9 times (95% CI = 1.3-11.8) at the risk of becoming low or middle achievers during the end of semester examination (P = 0.013). The multivariate analysis of "Agree" or "Disagree" and "Agree" or "Strongly Agree" was statistically significant. CONCLUSION: This study provides insight on how the pharmacy students learn and develop their cognitive functions. The results revealed that the FC activity with Poll Everywhere is an effective teaching-learning method.

RESUMO

BACKGROUND: The incidence of basal cell carcinoma (BCC) has increased during the previous decade. Mohs micrographic surgery (MMS) is the gold standard technique for BCCs. The aim of this study was to investigate the recurrence rate of periocular BCCs following MMS in a regional Mohs treatment facility in the United Kingdom. MATERIALS AND METHODS: The study comprised a retrospective case note review of 480 patients who underwent MMS from 2001 to 2006 for periocular BCC. Patients were identified via hospital coding databases. Medical records were reviewed, and the parameters collected include age, gender, previous BCCs and treatment modality, postoperative complications and subsequent management, site, size of lesion, histological subtype, and recurrence following MMS. RESULTS: Three hundred and ninety of the 480 patients identified were included. The remaining patients had died before the 5-year analysis (65), were lost to follow-up (20), or were identified as having Gorlin's syndrome (5). The majority of BCCs were 6-10 mm (42%) and nodular (45%). Six recurrences were identified (1.5%), including one (0.3%) primary BCC and five (6.5%) recurrent BCCs at the time of the MMS. The mean follow-up was 30 months (range 1-120 months). CONCLUSION: For BCC in the periocular region, MMS should be the treatment of choice for both primary and recurrent periocular BCCs. The increased recurrence rate, demonstrated by recurrent BCCs, highlights the need for a comprehensive follow-up.
