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: Although various technologies are used to evaluate driving skill, there are some limitations such as the limited range of the monitor and the possible risk of causing cybersickness. The purpose of this study is to investigate differences in the hazard perception and cybersickness experienced between novice and experienced drivers measured in a VR hazard perception test with a head-mounted display (HMD). Methods: The novice (n = 32) and the experienced drivers (n = 36) participated in the hazard perception test through the VR of an HMD. Results: The total number of identified hazards was 1071 in the novice drivers and 1376 in the experienced drivers. Two of the hazards appeared to be only identifiable through the HMD. A chi-square test revealed that experienced drivers were more likely to identify the hazards than the novice drivers (p < 0.05). The novice drivers appeared to identify “hazard prediction of the current behavior of other road users” more than other hazard types, unlike the experienced group. The Simulator Sickness Questionnaire scores indicated no significant difference in the different age or gender groups (p > 0.05). Conclusion: Our results suggest that the VR hazard perception test may be useful for evaluating patients’ driving skills.

Abstract Objective: To test the null hypothesis that there is no difference in facial profile shape, malocclusion class, or palatal morphology in Malay adults with and without obstructive sleep apnea (OSA). Materials and Methods: Subjects were 120 adult Malays aged 18 to 65 years (mean ± standard deviation [SD], 33.2 ± 13.31) divided into two groups of 60. Both groups underwent clinical examination and limited channel polysomnography (PSG). The mean OSA and control values were subjected to t-test and the chi square test. Results: Physical examination showed that 61.7% of the OSA patients were obese, and 41.7% of those obese patients had severe OSA. The mean body mass index (BMI) was significantly greater for the OSA group (33.2 kg/m2 ± 6.5) than for the control group (22.7 kg/m2 ± 3.5; P &lt; .001). The mean neck size and systolic blood pressure were greater for the OSA group (43.6 cm ± 6.02; 129.1 mm Hg ± 17.55) than for the control group (35.6 cm ± 3.52; 114.1 mm Hg ± 13.67; P &lt; .001). Clinical examination showed that the most frequent findings among OSA groups when compared with the control group were convex profiles (71.7%), Class II malocclusion (51.7%), and V palatal shape (53.3%), respectively; the chi square test revealed a significant difference in terms of facial profile and malocclusion class (P &lt; .05), but no significant difference in palatal shape was found. Conclusion: The null hypothesis is rejected. A convex facial profile and Class II malocclusion were significantly more common in the OSA group. The V palatal shape was a frequent finding in the OSA group.

Aim. The aim of the study was to determine the ultrasonic gallbladder wall thickness in normal adult Nigerians so as to create standards for defining gallbladder abnormalities in Nigerians. Method. Four hundred adults comprising 228 (57%) women and 172 (43%) men aged 16 - 78 years, who had normal clinical history and physical findings, were recruited. The gallbladder wall thickness was obtained in the supine, prone and right anterior oblique positions. Differences in gallbladder wall thickness were determined using the chi-square test, while the relationship between the ultrasound-measured gallbladder wall thickness and the subjects’ age, sex, height and weight were analysed using the Pearson product moment correlation. Normal ranges and related statistics were estimated and tabulated according to age group and sex. Results. The mean age of the subjects was 32±13.2 years. The mean gallbladder wall thickness range was 1.8 - 2.8 mm±0.5mm. The thickness range for females was 1.7 - 2.7 mm±0.5 mm, and that for males was 1.9 - 2.9 mm±0.5 mm.

Treatment of dental caries in children still remains challenging due to lack of cooperation with conventional treatment modalities. Recently, the use of Silver Diamine Fluoride (SDF) has proved useful in addressing this challenge. Aim: This clinical trial aimed to evaluate the effectiveness of Silver Diamine Fluoride (SDF) in arresting caries in children in Lagos, Nigeria. Methods: This was a phase III balanced randomized controlled school based interventional study on 240 children. The study group was treated with SDF while GIC was used in the control group. Follow up visits in 2 weeks, 1 month, and 3 months were carried out to assess the treatment outcome. Inferential statistics with the use of Pearson Chi-square test and Independent Student t-test were used at 5% level of significance. Results: There was significant relationship between SDF and caries arrest in 2 weeks, 1 month and 3 months’ assessment period (p = 0.001). The control group showed continuous decline (71.7%, 54.3% and 50.9%) in restorative success from 2 weeks to 3 months respectively. The mean ± SD and Confidence Interval (CI) of arrested caries in the SDF group were 113± 1.24 and 113.1 – 113.5 respectively. In the control group the mean ± SD and CI of restorative success were 69.3±11.8 and 67.2 – 71.4. The effect size was 5.24. Conclusion: The result of the study showed that SDF was effective in arresting caries in children without any harm and there was statistically significant difference in the use of 38% SDF in arresting caries in children.

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.

Objective To determine the efficacy of preoperative gabapentin on patient-reported pain levels and postoperative opioid requirements following sinonasal surgery. Study Design Retrospective review. Setting Academic institution. Methods Patients undergoing sinonasal surgery between July 2019 and January 2020 were followed. Groups were divided into those that received 600 mg of oral gabapentin 1 hour preoperatively (gabapentin) and those that did not (control). Postoperatively, each patient was counseled to use acetaminophen, ibuprofen, and oxycodone as needed for pain control. Patients completed a daily postoperative pain and medication log. Pain was measured by the visual analog scale (VAS) and opioid use by morphine equivalent dose (MED). Chi-square test and Wilcoxon test were used for data analysis. Results Fifty-seven patients were included (control, n = 28; gabapentin, n = 29). There was no significant difference in age, sex, or baseline Sinonasal Outcome Test–22 scores between the groups. The total MED, postoperative day (POD) 1-2 MED, POD 3-4 MED, and POD 5-6 MED did not differ significantly between the control (17.9, 12.2, 4.6, 1.5) and gabapentin (19.0, 8.9, 7.2, 3.5) groups ( P = .98, .25, .16, .44). The mean daily VAS score did not differ significantly between the control (3.1) and gabapentin (2.8) groups ( P = .81). The mean daily VAS score decreased significantly in both groups with each successive POD ( P = .004). Conclusion Preoperative gabapentin did not significantly reduce postoperative pain or opioid use. Postoperative discomfort following sinonasal surgery is mild, and opioid intake is minimal.

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.

Background: COVID-19 a pandemic caused by SARS CoV-2 has caused a wide impact globally. Clinical spectrum of COVID-19 ranges widely including asymptomatic infection, mild upper respiratory tract infection, severe pneumonia, ARDS, MODS and even death. Hypoalbuminemia in COVID-19 indicates severe disease. The aim of the study was to determine incidence of hypoalbuminemia and correlation of severity of hypoalbuminemia with COVID-19 positive SARI and COVID negative SARI patients.Methods: A study was conducted on 265 SARI patients who were admitted in hospitals attached to BMCRI. History was taken, general physical examination and a detailed systemic examination was done. Patients were categorized into mild, moderate and severe illness.  RT-PCR for COVID-19 patients done using throat and nasal swab. Total WBC counts and differential counts, platelet counts were estimated. Serum albumin levels were correlated with pneumonia severity and compared between COVID-19 positive and Negative SARI. And also, correlation with comorbities was done.Results: The study included 265 SARI patients, of which 135 were COVID-19 positive patients and 130 were COVID-19 negative. Patients categorized into moderate and severe SARI. Mean age of subjects with COVID-19 positive (severe) was higher- 58.70±15.598 followed by COVID-19 positive (moderate)- 55.13±14.480. About 30% (N=90) were belong to severe SARI group, Chi-square test showed statistical significant association with respect to age. Chi-square test showed no statistical significant association with respect to gender. Independent sample t test showed statistical difference with respect to S. albumin levels between COVID positive and COVID negative subjects. In COVID positive subjects, S. albumin levels showed statistical significant difference between moderate and severe sub groups whereas there was no statistical significant difference seen in COVID negative sub groups.Conclusions: The relationship between hypoalbuminemia and reduced survival in COVID-19 may have several explanations. First, acting as an anti-inflammatory and antioxidant protein, albumin may protect against cytokine storm. Second, albumin encompasses anticoagulant properties and inhibits oxidative stress-related clotting and platelet activation that occurs in severe COVID-19. Third, albumin is an inverse acute phase reactant. In our present study hypoalbuminemia was more significant in severe COVID-19 positive SARI patients compared to COVID-19 negative SARI patients hence, we could say that hypoalbuminemia is inversely related with COVID-19 severity and also more significant hypoalbuminemia in COVID-19 positive SARI.

Background: Anemia remains a crucial health problem in developing countries. Cardiac compromise and fatal complications usually occur at Hb of <5g/dL. The aim of the study was to determine possible etiologic and clinical profile in adult patients with very severe anemia (Hb of <5g/dL).Methods: A prospective observational study was conducted in a teaching hospital of Odisha over a period of 12months. A total of 70 patients of both men and non-pregnant women admitted to the medicine wards were included after exclusion. Detailed history, clinical examination and investigation findings were recorded. Independent ‘t’ test, Wilcoxon rank sum test, Pearson chi-square test and Fisher exact test were used as applicable, to compare the variables.Results: The mean Hb (g/dL) was 3.73 ±0.85 and the mean age of the study group was 53.34±17.75years. No significant difference was observed in the severity of anemia between the female (mean Hb of 3.56±0.93) and male patients (mean Hb of 3.87±0.77) (p=0.130). The most frequent etiology found was absolute iron deficiency (44.3%, n=31) and mostly (41.9%) found in the age group of ≥65years (p<0.001). Congestive cardiac failure was found in 20% (n=14) of patients and majority of patients (64.2%, n=9) were males (p<0.001).Conclusions: Iron deficiency is the principal cause of very severe anemia in adults rather than malignancy or anemia of chronic disease and only about one fourth of patients develop heart failure even with very severe anemia.
