Ophthalmic Complication Following Posterior Superior Alveolar Nerve Block for Tooth Extraction! A Rare Occurrence

One of the most commonly asked question by a patient who comes for extraction especially in the rural areas is whether the procedure will cause problems to the eye!! In reality however, ophthalmic complications following routine maxillary molar extractions are practically unheard of. When they occur they can be extremely unnerving not just to the patient but also to the surgeon. Patients generally panic which makes it tougher for the clinician to assess the situation. We present a case of a 26 year old female patient developing ophthalmic complication following local anesthesia administration during extraction of upper left maxillary third molar. In this article, ophthalmic complications arising from posterior superior alveolar nerve block are discussed and management guidelines are highlighted.     

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.     

A family with a complex clinical presentation characterized by arrhythmogenic right ventricular dysplasia/cardiomyopathy and features of branchio‐oculo‐facial syndrome

Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is a familial form of cardiomyopathy typically caused by mutations in genes that encode an element of the cardiac desmosome. Branchio‐oculo‐facial syndrome (BOFS) is a craniofacial disorder caused by TFAP2A mutations. In a family segregating ARVD/C, some members also had features of BOFS. Genetic testing for ARVD/C identified a mutation in PKP2, encoding plakophilin‐2, a component of the cardiac desmosome. Evaluation of dysmorphology by chromosome microarray (CMA) identified a 4.4 Mb deletion at chromosome 6p24 that included both TFAP2A and DSP, encoding desmoplakin, an additional component of the cardiac desmosome implicated in ARVD/C. A family member with both the 6p24 deletion and PKP2 mutation had more severe cardiac dysfunction. These findings suggest that this contiguous gene deletion contributes to both ARVD/C and BOFS, and that DSP haploinsufficiency may contribute to cardiomyopathy. This family provides a clinical example that underscores the need for careful evaluation in clinical scenarios where genetic heterogeneity is known to exist. Finally, it suggests that individuals with unexplained cardiomyopathy and dysmorphic facial features may benefit from CMA analysis. © 2013 Wiley Periodicals, Inc.     

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.     

Opportunistic and other infections in HIV-infected children in Latin America compared to a similar cohort in the United States

Opportunistic and other infections have declined since the introduction of highly active antiretroviral therapy (HAART) in developed countries but few studies have addressed the impact of HAART in HIV-infected children from developing countries. This study examines the prevalence and incidence of opportunistic and other infections in Latin America during the HAART era. Vertically HIV-infected children enrolled in a cohort study between 2002 and 2007 were followed for the occurrence of 29 targeted infections. Cross-sectional and longitudinal analyses were performed to calculate the prevalence of infections before enrollment and the incidence rates of opportunistic and other infections after enrollment. Comparisons were made with data from a U.S. cohort (PACTG 219C). Of the 731 vertically HIV-infected children 568 (78%) had at least one opportunistic or other infection prior to enrollment. The most prevalent infections were bacterial pneumonia, oral candidiasis, varicella, tuberculosis, herpes zoster, and Pneumocystis jiroveci pneumonia. After enrollment, the overall incidence was 23.5 per 100 person-years; the most common infections (per 100 person-years) were bacterial pneumonia (7.8), varicella (3.0), dermatophyte infections (2.9), herpes simplex (2.5), and herpes zoster (1.8). All of these incidence rates were higher than those reported in PACTG 219C. The types and relative distribution of infections among HIV-infected children in Latin America in this study are similar to those seen in the United States but the incidence rates are higher. Further research is necessary to determine the reasons for these higher rates.     

Effect of long term low-fat dietary intervention on change in hemostatic factors: results from the Women's Health Initiative

Low-fat diet may play a role in prevention of cardiovascular disease (CVD) by altering the levels of hemostatic factors. There are yet limited data on the effects of low-fat diet on the circulating levels of these factors and existing studies are limited by small sample size and short duration of follow-up. We conducted an analysis in a subset of women (active arm = 723; control arm = 1036) within the Women's Health Initiative Dietary Modification Trial to investigate the long term effect of a low-fat diet on circulating levels of fibrinogen, factor VII concentration and factor VII activity among postmenopausal women aged 50-79 years. Using linear mixed effects model with random intercept and data from three follow-up visits (years 1, 3 and 6) we evaluated the change in each factor over time. Overall, the changes in these factors were small (less than 5%) in both the arms of the trials at the end of intervention and there was no significant difference in mean change between the two arms. Our results indicate that the low-fat dietary intervention was not associated with significant changes in hemostatic factors among postmenopausal women.     

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.
