ABSTRACT Background Human identification is one of the most challenging subjects that man has been confronted with. The fingerprints and DNA comparison are the most commonly used techniques in human identification. Palatoscopy is one of the recently developing methods to identify a victim-based on the palatal rugae pattern. Aims and objectives The aim of the study was to analyze the different rugae pattern in Puducherry population and to find whether palatoscopy is a useful tool in human identification and sex determination. Materials and methods The studies consist of 100 male and female patients between the age group of 20 to 35 years. The rugae pattern was divided assessed based on Kotze classification. Chi-square test and one-way analysis was used to study the statistical significance. Results Wavy pattern appeared to be the most predominant pattern followed by curved, straight, branched and circular pattern in both male and female patients. The shape and number of rugae pattern is similar in male and females. Conclusion The present study concludes that wavy pattern appear to be most common rugae pattern among Puducherry population. No significant difference in rugae pattern was noted among the male and female group. Rugae pattern is unique to each individual and can be an effective tool in human identification.

Objective: To determine the number and pattern of palatal rugae in Nepalese subjects and to find the association of gender with the number and pattern of palatal rugae. Materials & Method: 200 Nepalese subjects comprising of 100 male and 100 female were randomly selected and their maxillary casts were examined for the palatal rugae length applying the classification proposed by Thomas and Kotze and palatal rugae pattern was recorded using the classification given by Kapali. Statistical analysis using Student t-test was applied for comparing the number of palatal rugae between right and left sides. Chi square test was used to find the association between gender and number of rugae as well as the pattern. Result: The study demonstrated that the mean number of primary palatal rugae on left side was predominant, similarly wavy pattern was the most predominant in Nepalese subjects. No statistical significant difference was noticed in the palatal rugae number and pattern between the gender groups. Conclusion: The study found predominant palatal form in Nepalese subjects which might have superior effectiveness in population differentiation and may be used as an effective tool in forensic odontology identification.

Background: Missing to detect an ischemic stroke in the emergency department leads to miss acute interventions and treatment with secondary prevention therapy. Our study examined the diagnosis of stroke in the emergency department (ED) and neurology department of an academic teaching hospital. Methods and Materials: A retrospective chart review was performed from March 2017 to March 2018. ED medical document (chart) were reviewed by a stroke neurologist to collect the clinical diagnosis and characteristics of ischemic stroke patients. For determining the cases of misdiagnosed and over diagnosed data, the administrative data codes were compared with the chart adjudicated diagnosis. The adjusted estimate of effect was estimated through testing the significant variables in a multivariable model. The comparisons were done with chi square test. Statistical significance was considered at P < 0.05. Results: Of 861 patients of the study, 54% were males and 43% were females; and the mean age of them was 66.51 ± 15.70. We find no statically significant difference between patient’s Glasgow Coma Scale (GCS) in the emergency department (12.87±3.25) and patients GCS in the neurology department (11.77±5.15). There were 18 (2.2%) overdiagnosed of ischemic stroke, 8 (0.9%) misdiagnosed of ischemic stroke and 36 (4.1%) misdiagnosed of hemorrhagic strokes in the emergency department. Conclusion: There was no significant difference between impression of stroke in the emergency department and diagnosis at the neurology department.

Segmentation has been frequently used to study individual consumer behavior against its preference. Consumer preferences indicate consumer requirements for a product. This study aims to analyze consumer preferences based on gender segmentation (male and female) and age segmentation (adolescents, adults, and elderl y). Consumer preferences wer e studied based on three aspects, namely functionality, usability, and pleasure that are applied to food products. Respondents consisted of 225 consumers of ice cream products. Crosstab analysis was used to describe consumer preferences, while chi-square test was applied to analyse the difference of consumer preference based on predetermined segmentation. The result showed that there was no significant difference for male and female consumer preferences for three aspects. Furthermore, on the attributes of taste (functionality), shape (usability) and appearance (pleasure) there were significant differences. Based on the age segmentation there were differences in consumer preferences for aspects of functionality and pleasure. Howe ver, we also found that there was no significant difference in product attributes of those aspects, except for the colour attribute. Different consumer preferences obtained in different segments can be used as a reference to customer requirements for design ing customized products. Ultimately, the products can be tailored to consumer preferences in each segment.

Abstract Study aim: This study aimed to determine the knowledge and skills of swimming coaches in providing first aid and cardiopulmonary resuscitation (CPR). Material and methods: The sample consisted of 59 swimming coaches who responded to non-standardized questionnaire. The collected data were processed by the statistical program IBM SPSS (20.0), using the Chi-square test with cross-tabulation, with a level of statistical significance p ≤ 0.05. Results: Obtained data showed a statistically significant difference in the knowledge of swimming coaches about first aid and CPR in relation to coaching experience (p = 0.025); in the knowledge of providing first aid and CPR between coaches who have a certificate of first aid and CPR and those who do not (p = 0.006) and in first aid and CPR knowledge between coaches who have renewed their first aid and CPR knowledge and those who did not (p = 0.045). Conclusion: Based on the findings of the present study, swimming coaches included in this research did not have enough knowledge and skills in first aid and CPR, which makes swimming programs unsafe. By obliging swimming coaches to acquire and constantly improve their knowledge and skills in first aid and CPR, the environment for all swimming programs would become safer.

Abstract Introduction Telemedicine is a resource to help limit in-person contacts, which has become increasingly utilized during the Coronavirus pandemic. In the last year, most health care systems have attempted to limit in-person visits in order to help decrease Coronavirus transmission. A retrospective analysis was conducted to determine if the use of telemedicine resulted in an increase in cancellation rates. The data on cancellation rates of a burn clinic using telemedicine was collected for a seven-month period in 2020. The increased rate of cancellations for telemedicine visits compared to in-person visits was found to be statistically significant. Methods A retrospective analysis of patient cancellation rates for 2,463 burn outpatient visits seen in a burn clinic associated with a large tertiary referral burn center was performed covering the time period between April 1st and August 30th of 2020. Cancellations of initial visits for new or recently discharged patients were not included as telemedicine visits were only offered for established burn outpatients. Rescheduling rates for both groups were calculated to assess a potential impact on cancellations. Telemedicine visits consisted of patient encounters conducted by phone or by live video chat. Statistical significance was determined using chi-square test with an accepted p &lt; 0.05. Results The study included 2,463 scheduled outpatient visits comprising 511 telemedicine visits and 1,952 in-person visits. A cancellation rate of 47% occurred for telemedicine visits and a cancellation rate of 40% was observed with in-person visits. Patient visits conducted using telemedicine were associated with a higher cancellation rate (p=0.013). The reschedule rate for telemedicine visits was 22% while in-person visits had a rate of 25% showing no significant association (p = 0.45). Conclusions Telemedicine follow-up visits were found to have an increased rate of cancellations compared to in-person visits. Rates of rescheduling showed no significant difference between groups.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

Background: The palatal rugae are special constructions that are inalterable in their position and pattern during the lifestyles of an individual. This imparts them an exceptional role in the forensic dentistry and may play potential role in malocclusion identification. This study was aimed to see association of rugae pattern with sagittal skeletal malocclusion in orthodontic patients visiting tertiary care hospital. Methods: This cross-sectional examination was completed on pretreatment records (lateral Cephalometric radiographs and maxillary dental casts) of 384 subjects at the orthodontic department of Ziauddin Dental Hospital, Karachi. The study duration was from January to July 2019. The samples were sub-divided into three sagittal skeletal groups based on ANB angle proposed by Steiner’s on lateral Cephalometric radiographs (Class I with ANB angle between 0° to 4°; Class II: ANB angle greater than 5°; Class III: ANB angle less than 0°). The shapes of three most-anterior primary rugae were then evaluated bilaterally using Kapali et al., Classification. Chi Square test was applied to find association of rugae pattern among sagittal skeletal malocclusions groups. Results: Circular and curved rugae shapes were the most prevalent in all skeletal malocclusions. The primary palatal rugae pattern was seen to be significantly different among three skeletal malocclusion groups (p<0.05). The right and left sided palatal rugae pattern showed significant difference in all three skeletal malocclusion groups (p<0.05). Conclusion: The present study showed no specific palatal rugae pattern associated with sagittal skeletal malocclusion. Further studies on larger sample and use of modern 3D technologies to scan the maxillary casts are required for results that are more precise.

Abstract Background There is uncertainty surrounding the prognostic value of peritoneal cytology in low-risk endometrial cancer, especially in laparoscopic surgery. The objective of this retrospective study is to determine the prognostic significance of positive peritoneal cytology among patients with low-risk endometrial cancer and to compare it between laparoscopic surgery and conventional laparotomy. Methods From August 2008 to December 2019, all cases of pathologically confirmed stage IA grade 1 or 2 endometrial cancer were reviewed at Osaka Medical College. Statistical analyses used the Chi-square test and the Kaplan–Meier log rank. Results A total of 478 patients were identified: 438 with negative peritoneal cytology (232 who underwent laparotomy and 206 who undertook laparoscopic surgery) and 40 with positive peritoneal cytology (20 who underwent laparotomy and 20 who received laparoscopic surgery). Survival was significantly worse among patients with positive peritoneal cytology compared to patients with negative peritoneal cytology. However, there was no significant difference among patients with negative or positive peritoneal cytology between laparoscopic surgery and laparotomy. Conclusion This retrospective study suggests that, while peritoneal cytology is an independent risk factor in patients with low-risk endometrial cancer, laparoscopic surgery does not influence the survival outcome when compared to laparotomy.
