This paper reports a case of a labial pyogenic granuloma in the lower lip of a 15‐year‐old boy due to chronic trauma from the maxillary left central incisor. The case report is based on the CARE (CAse REport) Checklist developed by the Joanna Briggs Institute. A further aim is to present a mini‐review about the link between labial pyogenic granuloma and trauma, through searching in three databases (MEDLINE, EMBASE, and Global Health) using a predefined search strategy and keywords. The Cochrane Library and PROSPERO were also searched for published and ongoing systematic reviews, respectively. Only five case reports were found that discussed the link between labial pyogenic granuloma and trauma. Chronic trauma was found to be the most common cause of pyogenic granuloma affecting the lip. Excisional biopsy was the preferable treatment due to the advantage of allowing histopathologic assessment, which is necessary to establish a definitive diagnosis. Dentists advise to include labial pyogenic granuloma in their differential diagnosis (ie, mucocele, cyst, abscess, hematoma, minor salivary gland trauma or tumor) when assessing lesions in the upper and lower lips, in particular when related to a history of trauma.

Background: Treatment of osteoradionecrosis (ORN) is not a straightforward task, and it is unpredictable. However, a combination of pentoxifylline; an antioxidant drug, and tocopherol (vitamin E) works as a potent antifibrotic agent and have shown recently both significant and impressive results.Aims: This scoping review aims to investigate the most prescribed regimen of pentoxifylline and tocopherol with/without clodronate for the management of ORN.Methods: Ovid MEDLINE and EMBASE databases were used to retrieve eligible studies using planned search keywords. PROSPERO and Cohcarne library were also searched for ongoing or published systematic reviews, respectively. Included articles were grouped thematically according to the type of studies and accordingly they were summarized.Results: A total of 27 articles met the inclusion criteria and included in the data analyses. All the included articles were published between 1997 and 2020. Of these 27 included studies, two were randomized control trials, two were systematic reviews, six were retrospective studies, five were observational studies, seven were narrative reviews, four were case reports, and lastly one was an in-vitro study. Conclusions:Treatment by PENTO (800 mg of pentoxifylline + 1000 IU of tocopherol) once daily for an early established ORN or PENTOCLO (PENTO regimen + 1600 mg of clodronate) once daily for the refractory/severe cases of ORN appears to be the most prescribed regimen used for the treatment of ORN using these drugs. These drugs appear safe, effective and inexpensive for the treatment of ORN.

Background:Benchmarking of central line associated blood stream infection (CLABSI) rates remains a problem in developing countries due to the variations in surveillance practices and/or infection risk as non-availability of national data.Aim:The aim of the following study was to find out the CLABSI rate before and after central line (CL) bundle intervention and compare the outcome with international surveillance data.Subjects and Methods:This prospective longitudinal cohort study on adult intensive care unit patients was conducted at Hera General Hospital, Makkah Saudi Arabia from January 1 to December 31, 2012. Five key components of bundle were selected; hand hygiene, maximal barrier precautions upon insertion, skin antisepsis, optimum site selection and daily review of line necessity with prompt removal of unnecessary lines. Post-intervention CLABSI rate was compared with National Healthcare Safety Network (NHSN) and International Nosocomial Infection Control Consortium (INICC) rates. Statistical Package for the Social Sciences (SPSS) 14.0 software (SPSS Inc., 233 South Wacker Drive, 11th floor Chicago, USA) was used for statistical analysis included regression analysis for correlation. Statistical significance was set at P < 0.05.Results:CLABSI rate was reduced from 10.1 to 6.5 per 1000 CL days after interventions and had significant correlation with overall bundle compliance rate 87.6% (P = 0.02) On benchmarking, CLABSI rate after the intervention was similar to mean pool value of INICC (6.8) while higher than NHSN (3.1). The most common microorganisms isolated were; methicillin-resistant Staphylococcus aureus (30.8%), Acinetobacter baumanii (23.3%) and Enterococcus faecalis (15.4%).Conclusion:We found that INICC data was a better benchmarking tool comparative to NHSN because it represents the countries that are developing the surveillance system. A multicenter national study is recommended.

AIM: This study aimed to assess the effectiveness of a recognised antimicrobial resistance (AMR) online module on knowledge and perception among dental students, using a randomised controlled trial study design. METHODS: Dental students (n = 64, aged 21-25 years) in clinical years agreed to participate in this triple-blinded, parallel, randomised controlled trial. There were 34 students in the study group and 30 students in the control group. The study group participated in an online course covering information about AMR, while students in the control group received another online course about microorganisms in dentistry. Both groups were assessed three times using online questionnaires: before the intervention (T1), after the intervention (T2), and two months later (T3). Each one of T1, T2 and T3 had 22 questions. The questions were repeated each time in T1, T2, and T3 asking about AMR but with different question format, to avoid the possibility of students to memorise the answers. RESULTS: The mean (m) of correct answers for all students on T1 was 12.56, with standard deviation (SD) of 3.2. On T2, m = 14.03 and SD = 3.85, and on T3, m = 14.36 and SD = 3.71. Scores ranged from 0 to 22. The participants in the study and control groups showed significant score improvements from T1 to T2, immediately after the intervention, but there was no significant difference between T2 and T3. The study group students’ scores did not improve significantly from T1 to T3, in contrast to the control group students’ scores. More importantly, there was no significant difference in improvement from T1 to T2 when comparing the study and control groups. CONCLUSION: Online courses might not be reliable learning methods for ensuring the optimal levels of AMR knowledge that are needed by dental practitioners.
