Patients' perception of cross-infection prevention in dentistry in Jordan.

PURPOSE: To explore the public perception of cross-infection prevention methods and their role in disease transmission, among patients attending Jordan University Hospital. MATERIALS AND METHODS: A systemic random sample of 310 dental patients with a mean (SD) age of 35.1 (14.80) years was selected (42.6% males and 57.4% female). Patients were interviewed prior to dental appointments by a specially trained and calibrated dentist. Responses of the patients were recorded in the structured questionnaire, maintaining their privacy and confidentiality. The data were entered into a Microsoft Excel spreadsheet and analysed using the SPSS statistical package to obtain the prevalence rates of patients' perceptions, which were then cross tabulated with gender, age and other variables. Significant differences were determined using the chi-square test, when appropriate. RESULTS: Of the respondents, 83.5% found it necessary for the dentist to wear gloves, and 65.8% stated the reason was to prevent cross infection from one patient to another. About three-quarters (74.8%) found it necessary for the dentist to wear a mask; when asked about the reason, 52.3% stated prevention of cross infection from dentist to patient. Regarding wearing protective glasses, about three-quarters (73.9%) found it unnecessary for the dentist to do so. The majority (76.8%) stated the method of HIV transmission was by dentists using needles previously used for patients infected with AIDS; 71% knew there is no vaccine against HIV. Only half (49%) reported that hepatitis could be transmitted by blood transfusion. Approximately two-thirds (67.4%) knew there is a vaccine against hepatitis. About 53.5% claimed their knowledge regarding infection transmission was obtained through watching television programmes about cross infection. CONCLUSION: Dental patients in Jordan need to be equipped with adequate knowledge about cross-infection control, thus education reinforcement is imperative.

The knowledge and attitude about HIV/AIDS among Jordanian dental students: (Clinical versus pre clinical students) at the University of Jordan.

BACKGROUND: The present study aimed to address the suspected deficiency in the level of understanding of HIV/AIDS among clinical and pre clinical dental students at the University of Jordan. In this cross-sectional study, structured questionnaires were distributed to fifth year dental students (n = 121) and to third year dental students (n = 144) in the academic year 2008/2009. FINDINGS: Significantly higher percentage of fifth-year students compared to third-year students felt that the teaching they received on cross-infection precautions and barrier dentistry was adequate (P < 0.001). Majority (84.2%) of fifth-year students were aware that individual carrying anti-HIV antibodies to be an HIV carrier, only 57.7% of third-year students were aware of this fact (P < 0.001). Majority recognized the association between Kaposi sarcoma, oral candidiasis and hairy leukoplakia with HIV/AIDS but knowledge of the association between HIV/AIDS with less frequent lesions was inadequate.Significantly higher proportion of third-year students compared to fifth-year (39.2% vs. 26.3%) thought that HIV patients should be referred to other centers or support groups for treatment (P = 0.04). CONCLUSIONS: The level of knowledge of Jordanian dental students about HIV and AIDS was generally acceptable; there were inadequacies, however, in their understanding regarding some aspects of AIDS epidemic which demands that dental school curriculum needs some improvement.

Uncommon incidental pseudoaneurysm. Diagnostic and management challenges.

OBJECTIVE: To analyze patients with uncommon incidental pseudoaneurysms, secondary to non-catheterization causes, and to discuss the peculiar clinical spectrum, and focus on some aspects of difference from post-catheterization pseudoaneurysms. METHODS: Eleven patients, 8 males and 3 females, were studied retrospectively in Jordan University Hospital, Amman, Jordan, between 2002-2008. Radiological studies performed included duplex sonography (DS), computed tomography (CT), conventional angiography, magnetic resonance imaging (MRI), and magnetic resonance angiography (MRA). RESULTS: Pseudoaneurysms were most commonly encountered in young males (63.6%), especially in the lower limb vessels (36%). Clinical findings were suggestive of pseudoaneurysms in 27% of our cases. Four out of the 8 DS scans showed the neck of pseudoaneurysms, and the to and fro waveform, the strongest indicators for pseudoaneurysms. Both CT with intravenous contrast and angiography failed to establish the diagnosis in one out of 5 cases. The MRI with MRA showed the pseudoaneurysms in 2 patients that underwent the scan. CONCLUSION: Incidental pseudoaneurysms are considered following iatrogenic procedures, penetrating, or blunt traumas with variable delay time. Young healthy males are at increased risks, as opposed to elderly females with calcified vessels in post-catheterization cases. Duplex sonography is less sensitive in incidental than post-catheterization pseudoaneurysms. The CT scan with intravenous contrast has high accuracy in establishing the diagnosis in small, or medium sized pseudoaneurysms. The MRI and MRA are accurate valuable studies and comparable to conventional angiography.
