Duration of orthodontic treatment with clear aligners versus fixed appliances in crowding cases: a systematic review.

OBJECTIVE: To critically appraise and assess the currently observed evidence about the difference in orthodontic treatment duration between clear aligners and fixed appliances in crowding cases. MATERIALS AND METHODS: An electronic search without limitations was conducted from inception to June 2023 covering nine databases: The Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Scopus, Web of Science, Google Scholar, Trip, CINAHL via EBSCO, EMBASE via OVID and ProQuest. Randomized controlled trials (RCTs) and matched non-randomized studies were included in this systematic review. Risk of Bias was assessed via Cochrane's tool (RoB 2) for RCTs and ROBINS-I tool for non-randomized studies. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework was employed to evaluate the overall quality of evidence. RESULTS: Out of the 3537 articles initially identified, ten eligible studies were included in this systematic review; six were RCTs. Only one study offered extraction-based treatment, while the other nine adopted non-extraction treatments. According to the GRADE, there is low evidence that treatment duration in mild to moderate crowding cases with clear aligners is similar to that in fixed orthodontic appliances. Meta-analysis was not administered due to high inconsistency. CONCLUSIONS: Based on currently available information, there was no significant difference in the treatment duration between the CA and FA groups in mild to moderate crowding cases. Further well-performed RCTs, especially in severe cases, are required. CLINICAL RELEVANCE: Time efficiency is an essential outcome measure for clinical orthodontic practice. While the type of appliance used is a critical determinant of treatment duration, orthodontists should be aware of other factors that can significantly impact treatment time, such as patient and treatment-related factors.

The Clinical Profile of Unilateral and Bilateral Optic Disc Swelling in a Tertiary Center in Northern Malaysia.

Background Optic disc swelling (ODS) is a pathological condition with a variety of causes, including optic neuritis (ON), anterior ischemic optic neuropathy, and papilledema. Determining the causes of ODS is critical due to the possibilities of vision- or life-threatening diseases, such as space-occupying lesions. This study aimed to investigate the clinical profile of unilateral and bilateral ODS in Penang Hospital, Malaysia. Methodology This retrospective, descriptive study was conducted in Penang Hospital. Medical records of patients who were diagnosed with ODS from June 2018 until June 2020 in Penang Hospital Eye Emergency Clinic were reviewed. We excluded patients who defaulted on subsequent three months of follow up and those with pseudo-ODS. Results ODS was diagnosed in 43 patients who were all included in the study. Majority were females 55.8% (n = 24), with age ranging from 16 to 78 years. ON contributed most (41.9%, n = 18), followed by non-arteritic anterior ischemic optic neuropathy (NA-AION) (34.9%, n = 15), and papilledema (9.3%, n = 4). Other causes (14%, n = 6) included diabetic papillitis (n = 1), hypertensive retinopathy (n = 1), and central retinal vein occlusion (n = 4). Poor mean initial visual acuity was seen in patients with ON (1.07 ± 0.68) and NA-AION (1.33 ± 0.67). ON showed better final visual outcomes compared to NA-AION at the one-year follow-up. Conclusions ON and NA-AION were identified as the two most common causes of ODS in Penang Hospital for both unilateral and bilateral presentations. Most cases presented with poor initial visual acuity. After one year of follow-up, good visual recovery was seen in ON cases compared to other cases. These results were comparable with studies conducted in other Asian counties.

Ocular Cat Bite Injury: A Case Report and Literature Review.

Ocular injury related to cat bites is rare, and no proper guidelines have been suggested for the treatment of such injuries. We report a rare case of zone II penetrating ocular injury secondary to a cat bite. A 49-year-old lady presented with left eye pain following a cat bite over the left eye, which occurred four hours prior to the presentation. Immediate primary closure with intravitreal antibiotic injections was given. Systemic and topical antibiotic treatments were administered. Presenting visual acuity was hand motion, which improved to 20/20 at six months follow-up. Throughout this period, there were no signs of endophthalmitis. Prompt and effective antibiotic administration with early surgical intervention contributed to a good visual prognosis in this case.

INITIATE: An Intelligent Adaptive Alert Environment.

Exposure to a large volume of alerts generated by medical Alert Generating Systems (AGS) such as drug-drug interaction softwares or clinical decision support systems over-whelms users and causes alert fatigue in them. Some of alert fatigue effects are ignoring crucial alerts and longer response times. A common approach to avoid alert fatigue is to devise mechanisms in AGS to stop them from generating alerts that are deemed irrelevant. In this paper, we present a novel framework called INITIATE: an INtellIgent adapTIve AlerT Environment to avoid alert fatigue by managing alerts generated by one or more AGS. We have identified and categories the lifecycle of different alerts and have developed alert management logic as per the alerts' lifecycle. Our framework incorporates an ontology that represents the alert management strategy and an alert management engine that executes this strategy. Our alert management framework offers the following features: (1) Adaptability based on users' feedback; (2) Personalization and aggregation of messages; and (3) Connection to Electronic Medical Records by implementing a HL7 Clinical Document Architecture parser.

Open randomized clinical trial of laparoscopic versus open incisional hernia repair.

BACKGROUND: Incisional hernia is a common complication following abdominal surgery. Although the use of prosthetics has decreased recurrence rates, the standard open approach is still unsatisfactory. Laparoscopic techniques are an attempt to provide similar outcomes with the advantages of minimally invasive surgery. METHODS: Open randomized controlled clinical trial with follow-up at 1, 2, 3, 7, and 15 days, and 1, 3, and 12 months from hernia repair. The study was carried out in the surgery departments of three general hospitals of the Valencia Health Agency. OBJECTIVES: To compare laparoscopic with anterior open repair using health-related quality of life outcomes as main endpoints. RESULTS: Eighty-four patients with incisional hernia were randomly allocated to an open group (OG) (n = 39) or to a laparoscopic group (LG) (n = 45). Seventy-four patients completed 1-year follow up. Mean length of stay and time to oral intake were similar between groups. Operative time was 32 min longer in the LG (p < 0.001). Conversion rate was 11%. The local complication rate was superior in the LG (33.3% versus 5.2%) (p < 0.001). Recurrence rate at 1 year (7.9% versus 9.7%) was similar in the two groups. There were no significant differences in the pain scores or the EQ5D tariffs between the two groups during follow-up. CONCLUSIONS: Laparoscopic incisional hernia repair does not seem to be a better procedure than the open anterior technique in terms of operative time, hospitalization, complications, pain or quality of life.
