Clinical Efficacy of Subgingivally Delivered 1.2% Atorvastatin in Chronic Periodontitis: A Randomized Controlled Clinical Trial

Background: Atorvastatin (ATV) is a specific competitive inhibitor of 3‐hydroxy‐2‐methyl‐glutaryl coenzyme A reductase. Recently, statins have shown pleiotropic effects such as anti‐inflammation and bone stimulation. The aim of the present study is to investigate the effectiveness of 1.2% ATV as an adjunct to scaling and root planing (SRP) in the treatment of intrabony defects (IBDs). Methods: Sixty individuals were randomized into two treatment groups: SRP plus 1.2% ATV and SRP plus placebo gel. At baseline and 3, 6, and 9 months, clinical parameters, which included modified sulcus bleeding index, plaque index, probing depth (PD), and clinical attachment level (CAL), were recorded at baseline. Radiologic assessment of IBD fill was done using computer‐aided software at baseline and 6 and 9 months. Results: Mean PD reduction and mean CAL gain were greater in the ATV group than the placebo group at 3, 6, and 9 months. A significantly greater mean percentage of radiographic bone fill was found in the ATV group (35.49% ± 5.50%) compared to the placebo group (1.82% ± 1.32%) after 9 months. Conclusion: ATV as an adjunct to SRP can provide a new direction in the management of IBDs.     

Life and living in advanced age: A cohort study in New Zealand -Te Puawaitanga o Nga Tapuwae Kia Ora Tonu, LiLACS NZ: Study protocol

ABSTRACT: BACKGROUND: The number of people of advanced age (85 years and older) is increasing and health systems may be challenged by increasing health-related needs. Recent overseas evidence suggests relatively high levels of wellbeing in this group, however little is known about people of advanced age, particularly the indigenous Maori, in Aotearoa, New Zealand. This paper outlines the methods of the study Life and Living in Advanced Age: A Cohort Study in New Zealand. The study aimed to establish predictors of successful advanced ageing and understand the relative importance of health, frailty, cultural, social & economic factors to successful ageing for Maori and non-Maori in New Zealand. Methods/design A total population cohort study of those of advanced age. Two cohorts of equal size, Maori aged 80-90 and non-Maori aged 85, oversampling to enable sufficient power, were enrolled. A defined geographic region, living in the Bay of Plenty and Lakes District Health Board areas of New Zealand, defined the sampling frame. Runanga (Maori tribal organisations) and Primary Health Organisations were subcontracted to recruit on behalf of the University. Measures - a comprehensive interview schedule was piloted and administered by a trained interviewer using standardised techniques. Socio-demographic and personal history included tribal affiliation for Maori and participation in cultural practices; physical and psychological health status used standardised validated research tools; health behaviours included smoking, alcohol use and nutrition risk; and environmental data included local amenities, type of housing and neighbourhood. Social network structures and social support exchanges are recorded. Measures of physical function; gait speed, leg strength and balance, were completed. Everyday interests and activities, views on ageing and financial interests complete the interview. A physical assessment by a trained nurse included electrocardiograph, blood pressure, hearing and vision, anthropometric measures, respiratory function testing and blood samples. DISCUSSION: A longitudinal study of people of advanced age is underway in New Zealand. The health status of a population based sample of older people will be established and predictors of successful ageing determined.     

COVID-19 and Eye: A Review of Ophthalmic Manifestations of COVID-19

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has had health implications of unprecedented magnitude. The infection can range from asymptomatic, mild to life threatening respiratory distress. It can affect almost every organ of the body. Ophthalmologists world over are reporting various manifestations of the infection in the eye. This review was undertaken to help ophthalmologists recognize the possible manifestations and the stage of the viral disease when they commonly appear. Literature search was performed for the publications on ophthalmic manifestations of coronavirus disease-19 (COVID-19) between January 1, 2020 and January 31, 2021. 46 case reports, 8 case series, 11 cross sectional/cohort observational studies, 5 prospective interventional studies, 3 animal models/autopsy studies and 6 reviews/meta-analysis were included. Conjunctivitis is the most common manifestation and can develop at any stage of the disease. Direct effect due to virus, immune mediated tissue damage, activation of the coagulation cascade and prothrombotic state induced by the viral infection, the associated comorbidities and drugs used in the management are responsible for the findings in the eye. The viral ribonucleic acid (RNA) has been isolated from ocular tissues but the role of eye as a route for infection is yet to be substantiated. Ophthalmic manifestations may be the presenting feature of COVID-19 infection or they may develop several weeks after recovery. Ophthalmologists should be aware of the possible associations of ocular diseases with SARS-CoV-2 in order to ask relevant history, look for specific signs, advise appropriate tests and thereby mitigate the spread of infection as well as diagnose and initiate early treatment for life and vision threatening complications.     

A retrospective analysis of early experience with modified complete primary repair of exstrophy bladder (CPRE) in neonates and children

Objective:

To study the problems faced during the surgery and follow-up of modified complete primary repair of exstrophy (CPRE) technique. Initial experience with CPRE and its short- and long-term outcomes with respect to continence status and psychosocial impact are reported.

Materials and Methods:

A retrospective review of the hospital case records from March 2008 to September 2012 was performed. Data of patients with bladder exstrophy managed by a single paediatric surgeon using modified CPRE technique were analysed. Quality of life and psychosocial impact of the surgery were assessed using Pediatric Quality of Life Inventory (PedsQL 4.0) and compared with those of typical peers.

Results:

Eight children (age 4 days-12 years) underwent CPRE using modified Mitchell''s technique. Two patients (25%) experienced early postoperative complications, with infection and fistula developing in one each. All the patients were doing well on follow-up, with variable continence rates and good cosmesis. Mean duration of follow-up was 18.5 months (range 6 months-4 years). Five out of seven (71%) children were continent or partially continent. One case was lost to follow-up. PedsQL scores were comparable with those of age-matched peers in all domains except the social functioning domain in 8-12 years age group (83.53 ± 9.70 vs. 77.86 ± 10.22, P < 0.05).

Conclusion:

Our preliminary results with modified CPRE in neonates and children have been encouraging. No major complications were observed. Continence rate was satisfactory and cosmetic results were good. Though the technique is being practiced at several Indian centres, there is a paucity of comprehensive Indian data on CPRE.KEY WORDS: Bladder exstrophy, complete primary repair, urinary continence
