Pattern of dermatoses in the elderly population attending the dermatology clinic at a Tertiary Care Center in South-East Rajasthan

Introduction: The skin acts as the first line of defense for the body against external injuries. With aging, the architecture of the skin undergoes intrinsic changes that impair its capacity for repair. In addition, the aging skin is more susceptible to injury by external stimuli, including ultraviolet rays and environmental pollutants. The combination of these factors predisposes the elderly to a variety of dermatological disorders, including xerosis, pruritus, photoaging, eczematous disorders, and tumors. The elderly (>60 years of age) population in India accounted for 8.6% (104 million) in 2011, and the figure has been projected to increase to 19% by the year 2050. It is imperative to identify the pattern of cutaneous disorders in this population as skin care regimens aimed to improve epidermal function have been shown to be effective inthe prevention and treatment of some of these aging-associated cutaneous disorders. Objectives: The objective of the study was to identify the pattern of dermatoses among the elderly population attending the dermatology clinic at a tertiary care hospital in South?east Rajasthan. Materials and Methods: We conducted a cross-sectional descriptive study of patients above the age of 60 years who attended the dermatology clinic at a tertiary care hospital in South?east Rajasthan from May 2018 to May 2020. A combination of history, physical examination, and clinical investigations (when appropriate) were used to establish the diagnosis. Results: A total of 210 patients were included in this study. Most patients were between the age group of 60–65 years (40.47%). One hundred and thirty?eight were male (65.71%) and 72 were female (34.28%), with a male to female ratio of 1.9:1. Our study demonstrated that xerosis was one of the most common diagnoses seen in 126 cases (60%), followed by eczematous skin conditions seen in 82 cases (39%). Conclusion: The elderly constitute an important part of the population. Cutaneous disorders in the elderly range from mild disorders such as cherry angiomas to dermatological malignancies. Therefore, it is important to recognize the pattern of dermatosis in this population so that appropriate therapeutic and preventive strategies could be implemented.

Analysis of initial stress distribution in palatal bone around the implant in lingual orthodontics for single and double palatal implant systems: a FEM study

ABSTRACT Objective: To analyze and compare the Von Mises stress and principal stress distribution in palatal bone around the palatal implant in lingual orthodontics (LiO) for single and double palatal implant systems with varying lengths of lever arm. Methods: Two groups were assessed: single (Group 1) and double (Group 2) palatal implant systems, which were further divided into two subgroups, based on lever arm length, for analyzing stress in the palatal bone around the implant. Hence, two 3D finite element models of bilateral maxillary first premolar extraction cases were constructed in each system. Lingual brackets (0.018-in slot) were positioned at the center of the clinical crown. In both systems, 150g of retraction force was applied, and ANSYS v. 12.1 software was used to analyze and compare stress in the palatal bone around the palatal implant. Results: In this study, higher stress was observed at the inner threaded interface of cortical bone. Magnitude of Von Mises stress was higher in Group 2 (0.63 MPa and 0.65 MPa) in comparison to Group 1 (0.29 MPa and 0.29 MPa). Similarly, magnitude of principal stress was higher in Group 2, in comparison to Group 1. Higher stress was observed in the apical region of the implant-bone interface of cancellous bone. Conclusion: This study concluded that the Von Misses stress as well as principal stress in the palatal bone were within the optimal limit in both groups. Finally, it can be concluded that both systems (single and double palatal implant) were safe for the patients in clinical use of 150g of retraction force.

RESUMO Objetivo: Analisar e comparar as tensões de Von Mises e a distribuição das tensões principais no osso palatino ao redor de implantes palatinos em Ortodontia Lingual (OL) para sistemas de implantes palatinos unitários ou duplos com comprimentos variados do braço de alavanca. Métodos: Foram delineados dois grupos para o presente estudo: Grupo 1 - com sistema de implante palatino unitário e Grupo 2 - com sistema de implantes palatinos duplos. Em seguida, os grupos foram divididos em dois subgrupos, com base no comprimento do braço de alavanca, para analisar as tensões no osso palatino ao redor do implante. Para cada sistema, foram construídos dois modelos 3D de elementos finitos (MEF) de casos com extração bilateral de primeiros pré-molares superiores. Braquetes linguais (slot 0,018") foram posicionados no centro das coroas clínicas. Nos dois sistemas, foram aplicados 150g de força de retração nos dentes anteriores, e o software ANSYS v. 12.1 foi usado para analisar e comparar as tensões no osso palatino ao redor dos implantes. Resultados: Foram observados maiores níveis de tensões na parte interna rosqueada no osso cortical. A magnitude das tensões de Von Mises foi maior no Grupo 2 (0,63MPa e 0,65MPa) em comparação ao Grupo 1 (0,29MPa e 0,29MPa). De forma semelhante, foi observada maior magnitude das tensões principais no Grupo 2 do que no Grupo 1. Maiores tensões foram observadas na região apical da interface osso/implante no tecido ósseo esponjoso. Conclusão: A tensões de Von Mises e as tensões principais no osso palatino ficaram dentro do limite ideal em ambos os grupos. Ambos os sistemas de implantes palatinos (unitário e duplo) foram seguros para o uso clínico em pacientes com força de retração de 150g.

Ertugliflozin: a novel anti-diabetic drug

Diabetes Mellitus is a disorder of global proportion. Despite various treatment modalities presently being available, yet the desired glycaemic control and patient outcomes have not been achieved completely. Sodium glucose co-transporter type 2 inhibitors (SGLT2 inhibitors) are one such promising group of emerging drugs in diabetes treatment. Ertugliflozin prevents the reabsorption of glucose by inhibiting sodium-glucose cotransporter-2 (SGLT2) at proximal convoluted tubules. Ertugliflozin is available as 5mg and 15mg tablets. Ertugliflozin has been related to genital mycotic infections and urinary tract infections. Benefits of Ertugliflozin include better control on blood glucose, body weight and blood pressure.

Use of Arm Span as Proxy Indicator of Stature- An Anthropometric Study in Western U.P.

Background: Arm span is the most reliable anthropometric parameter to predict the body height of an individual. It is useful in predicting the age related loss in stature and in identifying individuals with disproportionate growth abnormalities and skeletal dysplasia. Previous studies show that stature can be measured effectively from various body parameters and length of long bones also. However, the relation between arm span and height was found to vary from race to race. The present study was undertaken to measure the stature as well as arm span and to determine whether there is any correlation between the stature and the arm span. Methods: This study was carried out with a total number of 400 subjects of Teerthanker Mahaveer University, 200 male and female each, age range (18-25). Stature was measured with the Stadiometer and arm span was measured using steel tape. The relationships between body height and arm span were determined using correlation coefficients. Then a linear regression analysis was evaluated to examine the extent to which arm span can reliably predict body height. Results: The results have shown the mean of arm span for the male subjects was 175.03± 7.00cm and the height 168.13±5.89 cm, while female arm span 159.01±6.32 cm and height 156.00±5.61cm. The arm span was consistently more than height. The arm span exceeded stature in 87.5% of the participants.Conclusion: There is a good correlation between body height and arm span.

Primary hyperoxaluria type 1 with a novel mutation.

Primary hyperoxaluria type 1 [PH1] is an autosomal recessive disorder caused by a deficiency of alanine-glyoxylate aminotransferase AGT, which is encoded by the AGXT gene. We report an Indian family with two affected siblings having a novel mutation in the AGXT gene inherited from the parents. The index case progressed to end stage renal disease at 5 months of age. His 4 month old sibling is presently under follow up with preserved renal function.
