Shisha smoking was significantly associated with mucosal hypertrophy when compared with cigarette smoking and controls. Shishasmoke contains higher level of toxicants as compared to cigarette smoke, and it causes more oxidative damage of tissues.

BACKGROUND & OBJECTIVE: The integrated curriculum adopted by the university effects the learning process of dental students. They prefer selective study of specific objectives rather than developing a deeper understanding of anatomy. Thus, students’ perceptions would be helpful in improving curriculum delivery, at university level, for beneficial future clinical roles. METHODOLOGY: A qualitative exploratory study in a dental college affiliated with regional medical university spread over three months.   Second year BDS class (50 students) was purposively chosen excluding first year students. Fifteen item questionnaire was developed and distributed via Google form  followed by inductive analysis. RESULTS:  Forty-eight students (96%) responded. Seven themes and eighteen subthemes emerged. Three themes expressed students’ preference for group study, small group discussion and visual learning style. Content of anatomy was suggested to be divided in two years by few. In theme “Anatomy assessment weightage” majority consented on same number of multiple-choice questions of anatomy as other subjects as all found it difficult to prepare it in one day with other subjects. Most of them considered such anatomy assessment weightage to have a positive impact on their future practitioner role. CONCLUSION: Dental students are satisfied with the content of anatomy in each block. Main concern raised is misalignment between anatomy assessment weightage and its delivered content. This drives students to do selective anatomy study in each block. This concern should be considered by university in redesigning future curriculum to equip students with necessary knowledge of anatomy required by dentists in their future roles.

Objectives: To study the effects of Nicotine on the survival rate of chick embryo and to evaluate the preventive role by the antioxidant green tea camellia sinensis. Study Design: Laboratory-based experimental study. Place and Duration of Study: Army Medical College, Rawalpindi, from Nov 2011 to Nov 2012. Methodology: A total of 75 Fayoumi fresh fertilized eggs were kept at Poultry Research Institute, Rawalpindi. Experimental solutions were injected to the eggs of four groups at forty-eight hours of incubation and the effect on the growth was recorded and compared with the control group. The control and experimental groups were observed to assess the effects of Nicotine and the role of antioxidant green tea Camellia sinensis on the survival rate and growth of chick embryo’s femur. Results: The control group (group-1) showed 100% survival rate of embryos. The experimental group-2 showed survival rate of 100% embryos and the group-3 and group-4 showed survival rate 50% and 70% of embryos, respectively. Conclusion: It was concluded that green tea decreases the oxidative stress caused by the Nicotine.

Objective: To determine the toxic effect of mosquito coil smoke inhalation on gross parameters of rat testis and explore the protective effect of Coenzyme Q10on testicular toxicity profile. Study Design: Laboratory-based experimental study. Place and Duration of Study: Department of Anatomy Army Medical College, Rawalpindi in collaboration with National Institute of Health, Islamabad, from Jan 2020 to Dec 2020. Methodology: This study was carried out among 30 male Sprague Dawley rats, distributed into three groups as 10 rats/group; group A served as control group, rats in group B were exposed to allethrin-based mosquito coil smoke 4hours/day for 12 weeks. Rats in group C were administered Coenzyme Q10 (10 mg/kg/day) via oral gavage for 12 weeks along with mosquito coil smoke exposure. At the end of study, gross parameters of body weight gain, testicular weight and volume, and relative tissue body weight index of testis were compared among groups. Results: Rats exposed to mosquito coil smoke alone showed significantly less weight gain (p<0.001)), testicular weight (p<0.001), volume (p<0.001), and relative tissue body weight index (p<0.001) as compared to control group. Rats administered Coenzyme Q10 along with mosquito coil smoke exposure exhibited significantly higher weight gain (p<0.001), testicular weight (p<0.001), volume (p<0.001) and relative tissue body weight index (p<0.001) as compared to rats exposed to mosquito coil smoke alone. Conclusion: Long-term inhalation of allethrin-based mosquito coil smoke caused testicular atrophy among rats, as evident by reduced testicular weight, volume and relative tissue body weight index. Whereas, prophylactic oral administration of Coenzyme......................

Objective: To assess the knowledge of epidemiology, transmission, prevention and control of rabies and to find the effect of an educational intervention in paramedical students of HITEC-IMS, Taxilla. Study Design: Quasi-experimental study. Place and Duration of Study: HITEC-IMS, Taxilla, from Mar to Sep 2019. Methodology: Study was carried out among paramedical students enrolled in 2 years diploma course in HITEC-IMS, Taxilla. Students were included by non-probability consecutive sampling. Results: Out of the total of 89 participants, the fatality of rabies was identified by 63 (70.8%) respondents in pre-test and by 84 (94.4%) respondents in post-test (p<0.001). Less than half of the participants knew about bats as a reservoir of rabies (22, 24.7%) in pre-test that raised to 59 participants (66.3%) in post-test (p<0.001). The proper sequence of protocol for postexposure prophylaxis (PEP) in un-vaccinated persons was identified by 42 (47.2%) respondents with an improvement of 27% in post-test (p<0.001). Proper order of rabies post-exposure prophylaxis (PEP) vaccine schedule in humans were identified by 16 (18.0%) respondents with an improvement of 6% in post-test (p=0.031). Conclusion: Knowledge of reservoir, mode of transmission, prevention and control of rabies after educational intervention showed a significant increase in the students.
