Identifying research obstacles; a cross sectional comparative study of perceptions of postgraduate medical and dental residents in three public sector medical colleges.

OBJECTIVE: To explore the attitude of postgraduate medical and dental residents about research work and to identify barriers in the way of research activities. METHODOLOGY: The cross-sectional study was conducted from May to July, 2018, at three public-sector medical and dental institutions in Quetta, the capital of Pakistan province of Balochistan, and comprised postgraduate residents. Data was collected using a pre-validated 16 item Likert scale questionnaire. Data was analysed using SPSS 23. RESULTS: Of the 72 subjects, 44(61.1%) were males. The overall mean age was 23.3±4.6 years (range: 28-30 years. The residents demonstrated willingness to conduct clinical research with a mean score of 4.36±0.65. There was no association of attitudes and barriers with socio-demographic and personal characteristics (p>0.05). Deficient lab facilities (p-<0.001), and inaccessibility to electronic and hospital data (p=0.003) were the major factors identified as research barriers. CONCLUSIONS: Barriers to research need to be addressed in designing research curricula to encourage and facilitate meaningful research.

Factors contributing to the lack of interest in research activities among postgraduate medical students.

OBJECTIVE: To determine the factors contributing to lack of interest in research activities among postgraduate residents in pediatric medicine. METHODS: This cross-sectional survey was conducted at The Children's Hospital Lahore, Pakistan in August 2017. The questionnaire was distributed to 105 postgraduate residents working in pediatric medicine department and 90 of them returned the completed proforma (response rate; 86%). Data was analyzed by SPSS version 22. RESULTS: Out of 90 residents' females were predominant (n=58/90; 64.4%). Mean age of the participants was 28.22 ± 2.092 years. Majority were unmarried (n=57; 63.3%). The highest mean score (2.31±0.697) was regarding "Lack of proper training for research", followed by "lack of previous exposure" (2.26±0.728) and "over loaded curriculum" (2.13±0.753). "Uncooperative faculty" and "funding issues" as a barrier towards research (p=0.016 and 0.014 respectively) was mentioned by males more than females. "Social and family commitment" was a significant perceived barrier in married residents as compared to unmarried residents (p=0.001). The residents in the younger age group were more reluctant to do research due to "over loaded curriculum" (p=0.038). CONCLUSION: Lack of proper training of research, lack of previous exposure and time management are the major factors affecting resident's research work, whereas married residents face more social/family constraints as compare to unmarried residents.

Haematological parameters and recurrent aphthous stomatitis.

OBJECTIVE: To find out the relationship between recurrent aphthous stomatitis (RAS) with deficiencies of haemoglobin, haematocrit, serum vitamin B12, serum Ferritin and red blood cells (RBC) Folate level. STUDY DESIGN: An analytical cross-sectional study. PLACE AND DURATION OF STUDY: Department of Oral Health Sciences, Shaikh Zayed Federal Postgraduate Medical Complex, Lahore, from February to July 2008. METHODOLOGY: Sixty consecutive subjects with active RAS were taken as the aphthous group; 60 age and gender matched subjects without RAS were as the Non-Aphthous group. Five milliliter blood was taken from both groups to evaluate the levels of serum B12, and RBC Folate through radio immuno assay and serum ferritin with enzyme linked immuno-sorbent assay tests. Complete blood count was carried out to determine the level of haemoglobin and haematocrit in both groups. Proportion of subjects with lower values was compared using 2 text of proportions with significance at p < 0.05. RESULTS: Serum Ferritin (p = 0.001), haematocrit (p < 0.001), RBC Folate (p < 0.001) and serum B12 (p < 0.001) were significantly lower in the RAS group. Combined deficiency state (haemoglobin, serum Ferritin, haematocrit, RBC Folate and serum B12) was identified in 13% (n = 8) RAS patients. CONCLUSION: Frequency of haematinic deficiencies was high in RAS patients. Serum B12 and RBC Folate were significantly low in aphthous group.

Effect on blood pressure and pulse rate after administration of an epinephrine containing dental local anaesthetic in hypertensive patients.

OBJECTIVE: To document safety for use, through recording changes in blood pressure and pulse rate, after administering 3.6 ml of a 2% lignocaine with 1:100,000 epinephrine dental local anaesthetic in a group of hypertensive patients. METHODOLOGY: The present study was conducted at Shaikh Zayed Medical Complex, Lahore, from May to December 2008, using a convenience sampling technique. The first 60 walk-in patients in the dental outpatient department planned for tooth extraction were enrolled in the study. Out of these 60 patients, 10 had pre-hypertension (BP = 130/90), 10 had stage 1 hypertension (BP =140-159/90-99) and 10 study subjects were suffering from stage 2 hypertension (BP = 160-179/100-109). Thirty age and sex matched normo-tensive patients requiring tooth extraction acted as the control group. All patients were administered two cartridges each of 1.8 ml of dental local anaesthesia containing 2% Lignocaine with 1:100,000 epinephrine. Blood pressure and pulse rate (PR) were the risk indicators that were measured thrice; pre-injection, 2 minutes and 5 minutes after injection. RESULTS: A decrease in systolic in stage 2 hypertension patients after 2 and 5 minutes of injections was noted. The diastolic BP (DBP) fell in all the groups after injections. Mean pulse rate increased from three to four beats per minute in all groups except in stage 2 hypertension patients where it slightly decreased. CONCLUSION: Epinephrine containing dental local anaesthesia decreased systolic blood pressure in stage 2 hypertension patients included in this study. There was an observed decrease of 21 mm Hg in systolic blood pressure hypertension patients but with no adverse effects.
