Knowledge and Attitudes of Saudi Dental Undergraduates on Oral Cancer

Oral cancer awareness among future dental practitioners may have an impact on the early detection and prevention of oral cancer. A cross-sectional survey was undertaken to assess the current knowledge of future Saudi dentists on oral cancer and their opinions on oral cancer prevention. A pretested questionnaire was sent to 550 undergraduate dental students in the fourth, fifth, and sixth year of the Al-Farabi College for Dentistry and Nursing, Riyadh, Saudi Arabia. Questions relating to knowledge of oral cancer, risk factors, and opinions on oral cancer prevention and practices were posed. Four hundred seventy-nine students returned the questionnaire (87.1 %). Eighty-one percent of respondents correctly answered questions relating to oral cancer awareness. Eighty-seven percent of respondents felt confident in performing a systematic oral examination to detect changes consistent with oral malignancy. Interestingly, 57 % of respondents had seen the use of oral cancer diagnostics aids. Thirty-seven percent of respondents felt inadequately trained to provide tobacco and alcohol cessation advice. There is a need to reinforce the undergraduate dental curriculum with regards to oral cancer education; particularly in its prevention and early detection. Incorporating the use of oral cancer diagnostic aids should be made mandatory.     

Effects of psychosocial stimulation on improving home environment and child-rearing practices: results from a community-based trial among severely malnourished children in Bangladesh

ABSTRACT: BACKGROUND: Parenting programmes are effective in enhancing parenting practices and child development. This study evaluated the effects of a intervention with psychosocial stimulation (PS) on the quality of the home environment and mothers' child-rearing practices in a community-based trial with severely malnourished Bangladeshi children. METHOD: Severely underweight children (n = 507), 6-24 months of age, were randomly assigned to five groups: PS; food supplementation (FS); PS + FS; clinic-control (CC); and, hospital-control (CH). PS included fortnightly follow-up visits for six months at community clinics where a play leader demonstrated play activities and gave education on child development and child rearing practices. FS comprised cereal-based supplements (150-300 kcal/day) for three months. All groups received medical care, micronutrient supplements and growth monitoring. Mothers were given the Home Observation for Measurement of the Environment (HOME) inventory and a questionnaire on parenting at baseline and after six months to assess the outcome. RESULTS: 322 children completed the study. After six months of intervention the PS + FS and PS groups benefitted in the total HOME score (depending on the comparison group, effect sizes varied from 0.66 to 0.33 SD) The PS + FS and PS groups also benefitted in two HOME subscales: maternal involvement (effect sizes: 0.8 to 0.55 SD) and play materials, (effect sizes: 0.46 to 0.6 SD), and child-rearing practices scores (effect size: 1.5 to 1.1 SD). The PS + FS group benefitted 4.0 points in total HOME score compared with CH, 4.8 points compared with CC and 4.5 points compared with FS (p < 0.001 for all). The PS group benefitted 2.4 points compared with CH (p = 0.035), 3.3 points compared with CC (p = 0.004), and 2.9 points compared with FS (p = 0.006). Child-rearing practice scores of the PS + FS group improved 7.7, 6.4 and 6.6 points and the PS group improved 8.5, 7.2 and 7.4 points more than CH, CC and FS, respectively (p < 0.001 for all). CONCLUSIONS: Child-rearing practices of mothers of severely malnourished children and the quality of their home environment can be improved through community-based psychosocial stimulation with or without food supplementation. This may be of importance to promote child development.     

Treatment of early rheumatoid arthritis

Recent advances in the understanding of the pathophysiology, aggressive treatment, and early detection of rheumatoid arthritis (RA) have changed the clinical, pathologic, and functional outcomes in patients with RA. Early aggressive treatment of RA has now become the norm in clinical practice rather than the use of the traditional pyramid approach of the last half of the twentieth century. Early treatment with monotherapy of traditional disease-modifying antirheumatic drugs (DMARDs) or biologics, combination traditional DMARD therapy and, especially, combination of biologic therapy and methotrexate, have revolutionized the treatment of RA, producing significant improvement in clinical, radiographic, and functional outcomes not seen previously. For the individual patient, we still cannot determine which medication or combination of medications will give the most complete response. There have been a number of recent, well-designed clinical trials that have tried to answer this question. Herein we review the evidence-based medicine that addresses these issues.     

Myiasis in Kuwait: nosocomial infections caused by lucilia sericata and Megaselia scalaris

Myiasis, the invasion of live human tissue by larvae of Diptera, is reported in the nasopharynx and a leg wound in two patients who were hospitalized for more than 72 hours in Mubarak Al-Kabeer Teaching Hospital in Kuwait City, Kuwait. On the fourth and fifth days after a 10-year-old Kuwaiti boy was admitted to the hospital intensive care unit in a bloodied and comatose state following a traffic accident, 'worms' that came out of his nostrils were fixed, cleared, and identified as second and third instar of Lucilia sericata (Diptera: Calliphoridae). After 14 days, 'worms' were seen in the original dressing of a 35-year-old Iranian man admitted to the Orthopedic Unit of the hospital with multiple lacerations and fractures. The larvae, in various stages of development, were identified as those of Megaselia scalaris (Diptera: Phoridae). Since the presence of larvae in both patients was recorded after a stay of at least 3-4 days in the hospital, by definition, these infestations are considered nosocomial.

Factors associated with poor outcomes in patients with lupus nephritis

The objective of this study was to identify the factors associated with important clinical outcomes in a case-control study of 213 patients with lupus nephritis. Included were 47% Hispanics, 44% African Americans and 9% Caucasians with a mean age of 28 years. Fifty-four (25%) patients reached the primary composite outcome of doubling serum creatinine, end-stage renal disease or death during a mean follow-up of 37 months. Thirty-four percent African Americans, 20% Hispanics and 10% Caucasians reached the primary composite outcome (P < 0.05). Patients reaching the composite outcome had predominantly proliferative lupus nephritis (WHO classes: 30% III, 32% IV, 18% V and 5% II, P < 0.025) with higher activity index score (7 +/- 6 versus 5 +/- 5, P < 0.05), chronicity index (CI) score (4 +/- 3 versus 2 +/- 2 unit, P < 0.025), higher baseline mean arterial pressure (MAP) (111 +/- 21 versus 102 +/- 14 mmHg, P < 0.025) and serum creatinine (1.9 +/- 1.3 versus 1.3 +/- 1.0 mg/dL, P < 0.025), but lower baseline hematocrit (29 +/- 6 versus 31 + 5%, P < 0.025) and complement C3 (54 +/- 26 versus 65 + 33 mg/dL, P < 0.025) compared to controls. More patients reaching the composite outcome had nephrotic range proteinuria compared to controls (74% versus 56%, P < 0.025). By multivariate analysis, CI (hazard ratio [95% CI] 1.18 [1.07-1.30] per point), MAP (HR 1.02 [1.00-1.03] per mmHg), and baseline serum creatinine (HR 1.26 [1.04-1.54] per mg/dL) were independently associated with the composite outcome. We concluded that hypertension and elevated serum creatinine at the time of the kidney biopsy as well as a high CI are associated with an increased the risk for chronic renal failure or death in patients with lupus nephritis.
