Effect of sociodemographic variables on complete denture satisfaction

PURPOSE

The objective of this study was to evaluate the effect of sociodemographic factors on quality of satisfaction towards denture treatment.

MATERIALS AND METHODS

One hundred subjects (filling inclusion criteria) who were wearing a denture for at least two months were enrolled and divided into five groups on the basis of sociodemographic variables (age, gender, literacy level, socio-economic and marital status). Questionnaires consisting of 38 questions (positive and negative attitude towards denture satisfaction) related to patients'' perception of clinical outcome in different domains such as mastication, appearance, speech, comfort, health, denture care and social status were scored by the subjects. Questions reflecting positive attitude were scored as 2, 1, or 0 (yes, uncertain and no, respectively) and reversely for the negative questions. Statistical analysis was done by using Statistical Package for Social Sciences (α = .05).

RESULTS

Level of denture satisfaction was higher in age subgroup belonging to 45 - 65 years of age in relation to comfort, health and denture care. Female and male showed significant priority for denture treatment because of esthetic and function respectively. Level of satisfaction was statistically significant with literacy level. Upper high income group showed significantly higher level of satisfaction only in case of social status. Married group showed significantly higher satisfaction level only with comfort.

CONCLUSION

Patients'' sociodemographic variables were influential factors on denture satisfaction.     

An evolutionary perspective on human female sexual desire

The maternal mortality rate in the Third World remains high despite the launch of the Safe Motherhood Initiative (SMI) in 1987. There are various sociocultural, political and economic factors which play a major role in this. The five main causes of maternal mortality are haemorrhage, sepsis, unsafe abortion, hypertensive disorders and obstructed labour. The key to safe motherhood lies in providing quality maternity care for all women. It is important to know the nature and the extent of the problems in the community so that appropriate technology can be introduced with optimum utilization of the available resources. The different ways of achieving safe motherhood are discussed with emphasis on community based interventions. The SMI goals can be reached provided the Safe Motherhood programmes are well funded, the community workers well trained and the leaders of the community and the nation dedicated.     

Study of PTPN22 1858C/T polymorphism in rheumatoid arthritis patients from Western India

BackgroundRheumatoid arthritis (RA) is an inflammatory autoimmune disorder with etiologies including genetic and environmental factors. Protein tyrosine phosphatase non-receptor type22 (PTPN22) 1858C/T polymorphism is widely suspected to be a susceptibility gene for RA in the non-HLA genes group.AimThis study aimed at determining whether PTPN22 1858C/T polymorphism is associated with RA patients from Western India and to evaluate its possible association with rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) autoantibodies.MethodsA total of 130 Indian RA patients and 100 age and sex matched normal controls were genotyped by polymerase chain reaction restriction fragment length polymorphism (PCR–RFLP) for the PTPN22 1858C/T polymorphism.ResultsRF positivity was seen among 73.8% RA patients studied and the overall incidence of anti-CCP antibodies was 86.2%. The homozygous genotype (T/T) was absent in both groups. Among RF positives, C/C homozygosity was 90.6% whereas 9.4% patients were C/T heterozygous. Among anti-CCP positives, 89.1% had C/C genotype while the remaining 10.9% have the C/T genotype. Statistically significant association was obtained between the polymorphism and anti-CCP positivity in RA patients (OR: 2.939, ‘p’ value = 0.0595).ConclusionOur study suggested that a positive autoantibody status may predispose an individual to RA. PTPN22 may act as a susceptibility gene only in certain ethnic groups and there is no direct association between PTPN22 C1858 polymorphism and RA patients from Western India. Still a larger study is needed to understand whether this polymorphism predisposes individual to disease-associated antibodies among Indian RA patients.     

A virtual COVID-19 ophthalmology rotation

The coronavirus (COVID-19) pandemic temporarily suspended medical student involvement in clinical rotations, resulting in the need to develop virtual clinical experiences. The cancellation of clinical ophthalmology electives and away rotations reduces opportunities for exposure to the field, to network with faculty, conduct research, and prepare for residency applications. We review the literature and discuss the impact and consequences of COVID-19 on undergraduate medical education with an emphasis on ophthalmic undergraduate medical education. We also discuss innovative learning modalities used from medical schools around the world during the COVID-19 pandemic such as virtual didactics, online cases, and telehealth. Finally, we describe a novel, virtual neuro-ophthalmology elective created to educate medical students on neuro-ophthalmology foundational principles, provide research and presentation opportunities, and build relationships with faculty members. These innovative approaches represent a step forward in further improving medical education in ophthalmology during COVID-19 pandemic and beyond.     

Detection of New Delhi Metallo‐beta‐Lactamase and Extended‐Spectrum beta‐Lactamase Genes in Escherichia coli Isolated from Mastitic Milk Samples

In this study, eight Escherichia coli isolates were obtained from milk samples of dairy cattle suffering from clinical/subclinical mastitis. Isolates were characterized for antimicrobial resistance traits and virulence genes. Results revealed that one isolate was harbouring New Delhi metallo‐beta‐lactamase gene (bla_NDM). Cloning and sequencing of the PCR amplicon confirmed the identity of the gene (GenBank accession no. KC769583 ) having 100% homology with bla_NDM‐5 (GenBank accession no. JN104597.1 ), and this isolate was susceptible to colistin, chloramphenicol and tetracycline only. Moreover, another isolate carried extended‐spectrum beta‐lactamase (ESBL) gene – bla_CTX‐M, and all isolates possessed bla_TEM gene. Of the eight isolates, only one isolate was positive for shiga toxin gene (stx2), and none were harbouring stx1 gene. Occurrence of New Delhi metallo‐beta‐lactamase (bla_NDM) in one E. coli isolate and ESBL genes in other isolates poses a potential threat to human health following possible entry and spread through food chain.     

Development and evaluation of SYBR Green I-based one-step real-time RT-PCR assay for detection and quantitation of Japanese encephalitis virus

One-step SYBR Green I-based real-time RT-PCR assay for rapid detection as well as quantitation of Japanese encephalitis virus (JEV) in acute-phase patient CSF samples by targeting the NS3 gene was developed. The assay developed in this study was found to be more sensitive as compared to conventional RT-PCR. The specificity of the reported assay system was established through melting curve analysis as well as by cross-reactivity studies with related members of Flavivirus. The applicability of Real-time PCR assay for clinical diagnosis was validated with 32 suspected acute-phase CSF samples of Gorakhpur epidemic, India, 2005. The improved sensitivity of real-time RT-PCR was reflected by picking up 10 additional samples with low copy number of template in comparison to conventional RT-PCR. The quantitation of the viral load in acute-phase CSF samples was done using a standard curve obtained by plotting cycle threshold (C(t)) values versus copy numbers of the RNA template. This is the first report on the application of real-time RT-PCR for detection as well as quantitation of JEV from patient CSF samples. These findings demonstrate the potential clinical application of the reported assay as a sensitive diagnostic test for rapid and real-time detection and quantitation of JEV in acute-phase clinical samples.     

弱视儿童的临床概况和遮盖治疗结果

目的：研究弱视的临床表现,以及对弱视患者进行遮盖治疗的效果。

方法：纵向研究。收集2015-04/2016-04 Dhulikhel医院眼科1 092例患者数据。对检出的弱视60例患儿的视力、主诉、年龄、屈光状态、双眼屈光度和注视方式进行评估。并对检出的弱视患儿进行遮盖治疗。

结果：在研究期间接受检查的1 092例儿童中,60例(5.49%)为弱视患者,其中,女性35例(58.30%),男性25例(41.70%),平均年龄为8.87±3.29岁。在43.3%(n=26)的弱视儿童中,经线性弱视是最常见的亚型,其次是远视性屈光参差性弱视(20%,n=12)。最常见的屈光不正是散光,占58.30%,其次是远视(22.50%)和近视(7.50%)。配戴眼镜联合遮盖治疗和主动视觉训练的依从性为73.30%(n=44)。3mo后不同治疗策略对弱视眼视力有显著改善(P=0.002)。

结论：在尼泊尔等发展中国家,弱视发病率和相关的视力损害仍然是一个公共卫生问题。意识的缺乏,社区或学龄前儿童视力筛查的缺乏,会导致儿童较晚出现症状,并最终导致明显的视力损害。通过筛选就诊地点、及时转诊和适当的干预措施,这种状况可得到改善。     

An Unusual Cause of Irritability in a Single Ventricle Patient after Bidirectional Glenn Shunt

The differential diagnosis for irritability in children is broad. In patients with congenital heart disease, one must strongly consider cardiac etiologies such as low cardiac output or elevated central venous pressure (CVP). In patients with single-ventricle physiology, the second stage of palliation includes bidirectional Glenn, which involves anastomosis of the superior vena cava to the pulmonary artery resulting in volume offloading of the single systemic ventricle. Typically, early in the post-operative period, patients may experience a headache due to the acute increase in CVP, and symptoms improve over time. Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a rare neurologic disorder in children, characterized by raised intracranial pressure (ICP) in the absence of brain parenchymal lesions or cerebrospinal fluid (CSF) abnormalities. While the pathogenesis of IIH is unknown, early recognition and treatment of IIH are important to prevent permanent vision loss. There are only rare reports of IIH in patients with Fontan circulation. To our knowledge, we report the first case of IIH in a 2-year-old female after bidirectional Glenn.
