Published: April 2018

Objectives: The purpose of the present study was to evaluate the efficacy of Ham's F-10 in maintaining the viability and reproducibility of PDL cells on avulsed teeth. Study design: Sixty mature, healthy extracted premolars were used. The experimental media used were Ham's F-10, Hank's balanced salt solution (HBSS), skim milk, and tap water (n = 15 specimens each). Cell viability was tested after 1, 3, 6, and 24 h storage in medium. Cell reproducibility was assessed by methyl-thiazol-tetrazolium (MTT) assay after1, 3, and 6 h storage in Ham's F-10, HBSS, and tap water. Results: The viability of PDL cells stored in Ham's F-10 and HBSS was significantly greater than that of samples stored in milk and tap water at all-time points (P&lt;0.001). A significant difference in cell viability between samples stored in Ham's F-10 and HBSS (favoring the former) was observed only at 6h (P=0.04). MTT assay results were significantly better for samples stored in Ham's F-10 and HBSS than for those stored in tap water (P&lt;0.001), with a significant difference between Ham's F-10 and HBSS observed only at 3h (P&lt;0.001).
Conclusions: Ham's F-10 is capable of preserving PDL cells viable and reproducible better than milk and tap water and similar to HBSS.

Os finos de pedreira que resultam da britagem de rochas graníticas, geralmente, são descartados e ficam estocados, ocupando áreas desnecessárias em pedreiras e expostas ao vento, chuva. Diante dessa situação, observa-se um desperdício da matéria-prima e visando a preservação ambiental se percebe a alternativa de empregar o pó de brita como agregado artificial em argamassa de revestimento. Para melhor entendimento dessa possibilidade, o artigo referenciou ao estudo comparativo da resistência à compressão e tração entre a argamassa convencional e a argamassa com adição de 20% de pó de brita granítica, confeccionados de acordo com os requisitos solicitados pela NBR 13281. Os dados foram obtidos pela ruptura de 12 corpos de prova cilíndricos e 12 corpos de prova prismáticos, nas idades de 7, 14, 21 e 28 dias, para ambos os tipos de argamassas, que foram dimensionadas com a resistência de projeto de 20 MPa, com o traço em volume para argamassa convencional de 1: 3,2: 0,4 (cimento, areia e cal hidratada) e para argamassa com adição de pó de brita de 1: 2,56: 0,64: 0,4 (cimento, areia, pó de brita e cal). Os resultados comprovaram que a resistência da argamassa com adição de pó de brita granítica se demostrou mais elevada. Palavras-chave: Finos de Pedreira. Granulometria. Densidade da Massa Fresca.AbstractQuarry fines resulting from the crushing of granitic rocks are usually discarded, stored in unnecessary quarry areas and exposed to wind, rain. Faced with this situation, a waste of the raw material is observed and environmental preservation is perceived as the alternative to use the crushed stone powder as an artificial aggregate in coating mortar. For a better understanding of this possibility, the article referred to the comparative study of the compressive strength and tensile strength between the conventional mortar and the mortar with the addition of 20% granite gravel powder, made according to the requirements of NBR 13281. The data were obtained by the rupture of 12 cylindrical specimens and 12 prismatic specimens, at the ages of 7, 14, 21 and 28 days, for both types of mortars, which were dimensioned with a design strength of 20 MPa, (Cement, sand and lime hydrate) and for mortar with addition of crushed stone powder of 1: 2.56: 0.64: 0.4 ( Cement, sand, gravel and lime powder). The results showed that the strength of the mortar with the addition of granite gravel powder was higher.Keywords: Quarry Fines. Grain Size. Fresh Mass Density.

A comparative study of effect of deviated nasal septum on nasal mucociliary clearance and to comprehend the effect of septal and turbinate surgeries on restoring the mucociliary clearance
Authors: B. C. Chandra Smitha , Bylappa Kiran 
Published: April 2018

<p class="abstract"><strong>Background:</strong> One of the important functions of nose is mucociliary transport by its epithelium. Any structural abnormalities of nose like deviated nasal septum, turbinate hypertrophy and polyps can easily damage the mucociliary clearance. This can lead to increased inflammation leading to osteomeatal complex obstruction and sinusitis. The purpose of the study is to determine the nasal mucociliary clearance time (NMC) in patients with deviated nasal septum. And to compare the changes in nasal mucociliary clearance time before and after septoplasty and septoplasty with turbinectomy.</p><p class="abstract"><strong>Methods:</strong> Nasal mucociliary clearance time was measured preoperatively in patients with deviated nasal septum on concave and convex side. Post operatively it was again recorded after septoplasty in group A and septoplasty with turbinectomy in group B. These values were compared with the control group C. </p><p class="abstract"><strong>Results:</strong> Postoperatively group A patients NMC time was 11.11±2.76 on convex side, 14.01±2.39 on concave side. In group B patients NMC time was 11.18±1.91 on convex side and 12.62±1.42 on concave side.</p><p class="abstract"><strong>Conclusions:</strong> Nasal septal deviation and hypertrophied inferior turbinates can cause considerable impairment of nasal mucociliary clearance. Septoplasty combined with partial inferior turbinectomy of compensatory hypertrophied inferior turbinate on concave side preserves the normal NMC mechanism on both the sides of nasal cavity than just septoplasty.</p>

Published: April 2018

<p class="abstract"><strong>Background:</strong> Mumps is an acute infectious disease caused by RNA virus. Clinically, the disease is presented as non suppurative enlargement and tenderness of one or both the parotid glands. The annual incidence of mumps in the absence of immunization is in the range of 100-1000 cases/100000 population. Mumps mostly occurs in children in age group of 5-9 years. The objectives of the study were to describe the epidemiological factors of cases admitted with parotid swelling; to describe the clinical features of patients admitted with parotid swelling; to assess the demographic factors in relation to complications.</p><p class="abstract"><strong>Methods:</strong> A cross sectional record based retrospective study was carried out at Sir Ronald Ross Institute of Tropical and Communicable Diseases, Hyderabad. All the cases admitted in year 2016 with unilateral or bilateral parotid swellings were included in the study. The study was carried out for 2 months. </p><p class="abstract"><strong>Results:</strong> The mean age of study population in present study was found to be 11.23 years. Around 35.9% of cases were found in the age group of 6-10 years. Males constituted 53.9% of study population and females were 46.1%. The mean duration between the onset of symptoms and admission in hospital was found to be 3.5 days.

Authors: Panicker Vidya Bhargavan , Belaldavar B.P. 
Published: April 2018

<p class="abstract"><strong>Background:</strong> Deviation of normal pulmonary functions leads to dysfunction of the respiratory system and this affects the functions and vitality of other related systems. Pulmonary function tests give valuable information on the state of airways, lung volumes and lung function. Hence, the present study aimed to evaluate the effectiveness of septoplasty on pulmonary function tests in symptomatic deviated nasal septum cases.</p><p class="abstract"><strong>Methods:</strong> A total of 35 patients (septoplasty: 31; septorhinoplasty: 4) with deviated nasal septum were involved in the study. Demographic data, clinical and physical examination including anterior and posterior rhinoscopy was performed. RMS Helios 702 spirometer was used to perform pre- and postoperative pulmonary function tests. Forced vital capacity (FVC), forced expiratory volume (FEV1) in 1 second, peak expiratory flow rate, and the ratio of FEV1 to FVC were the parameters measured. SPSSV. 17 was used to analyse the data. </p><p class="abstract"><strong>Results:</strong> The deviation was most commonly seen on the left side (54%), affecting mostly the cartilaginous septum (54%). Among patients with septoplasty, the postoperative values of FVC (p&lt;0.05), FEV1 (p&lt;0.05), and peak expiratory flow (p&lt;0.05) were higher than the preoperative values and the results were statistically significant. Age, gender, laterality and duration of deviation, headache and inferior turbinate hypertrophy did not play a significant role in the enhancement of pulmonary functions after septoplasty.</p><p class="abstract"><strong>Conclusions:</strong> A favorable outcome in pulmonary function was observed in patients with deviated nasal septum after septoplasty. However, due to limited sample size, it is advisable to conduct the study in a larger sample to validate these results.</p>
