ABSTRACT
Background: Needle stick injury are the most common reason behind occupational blood exposure and most important source of exposure to another person’s blood.Methods: A cross-sectional observational questionnaire-based study of 450 undergraduate medical students which includes 100 from each years, Second year: Part I (II/I: Third Semester), Second year: Part II (II/III: Fifth Semester), Third Year (III: Seventh Semester), Fourth year (IV: Ninth Semester) MBBS and 50 Interns. The participation was voluntary and written consent was taken prior to enrollment. The objectives of study were explained, and validated questionnaire was administered to the students and collected in a single visit after 30-40 minutes.Results: The average age was 21.91±2.03 years. About 406 students were aware of disease transmitted by NSI. 189 students felt that occurrence of NSI, first person to be contacted is Medicine Physician. 208 don’t know of existence of PEP. 164 felt PEP is to be given for 4 weeks. According to 138 students PEP guidelines were proposed by NACO while 101 students felt WHO. 261 students felt that most probable chance of getting NSI was in emergency ward. 363students felt that need for NSI PEP training before clinical exposure is very important. 345 felt the need for insurance of HCWs for diseases transmitted by NSI.Conclusions: Medical students are highly vulnerable to NSI and there is need to provide adequate preventive measures, frequent training for needle stick injury and postexposure prophylaxis to all healthcare workers.
ABSTRACT
Background: The risk factors for patients with cardiovascular diseases and gastrointestinal diseases overlap. Majority of the patients have both problems coexistent. Thus, there is need of medicine that can be used for both the diseases.Methods: Rats weighing 150-250gm of either gender were procured for the study from central animal house. The animals were divided into 7 groups. Control group (Distilled water 2ml), diclofenac sodium (12mg/kg), diltiazem (10mg/kg), diltiazem (30mg/kg), diltiazem (60mg/kg), ranitidine (8mg/kg), ranitidine (16mg/kg). After six hours, scarification of animals was done by cervical dislocation. Size of ulcer, number of gastric ulcers, mean gastric irritancy index, ulcer index, and ulcer scoring were the parameters that were studied.Results: Diltiazem in dose of 10, 30 and 60 mg/kg showed reduction in all parameters in dose dependent manner. Diltiazem (60mg/kg) showed marked reduction in mean diameter of ulcerated surface area (0.46±0.36), number of ulcers (4.10±2.05), size of ulcers (1.07±0.48), total mucosal surface area (7.60±1.38), and total ulcerated surface area (0.263±0.3). Diltiazem (60mg/kg) showed significant reduction of the parameters as compared to other doses of Diltiazem. Also, diltiazem (60mg/kg) was comparable to Ranitidine in all the parameters. Diltiazem (60mg/kg) also showed reduction in average number of ulcers, ulcer index, mean gastric irritancy index and ulcer scoring as compared to diclofenac sodium (12mg/kg).Conclusions: Diltiazem has shown to have ulcer prevention property; this can be useful in patients having concomitant cardiovascular and gastrointestinal problems.
