Treatment of oral ulcers in dogs using adipose tissue-derived mesenchymal stem cells.

AIM: Adipose tissue Derived Mesenchymal Stem cells (ADMSCs) represent a promising toolfor new clinical concepts in supporting cellular therapy. The goal of this study was to investigate the effects of ADMSCs transplantation on oral ulcer healing in dogs. STUDY DESIGN: Mesenchymal stem cells were isolated from adipose tissues of dogs obtained by suction-assisted lipectomy (liposuction), by dish adherence and were expanded in culture. Oral ulcers were induced by topical application of formocresol in the oral cavity of 18 dogs. The dogs were classified into 3 groups. Either autologous ADMSCs, Corticosteriod (Dexamethasone) or vehicle (saline) was injected. The healing process of the ulcer was monitored histopathologically. Gene expression of vascular endothelial growth factor (VEGF), platelets derived growth factor (PDGF), epidermal growth factor (EGF) and collagen was assessed in biopsies obtained from all ulcers "as healing markers'", by real time polymerase chain reaction (PCR). RESULTS: ADMSCs group showed significantly accelerated oral ulcer healing compared with the Dexamethasone and control groups. There was increased expression of VEGF PDGF EGF and collagen genes in ADMSCs-treated ulcers compared with Dexamethasone and controls. CONCLUSION: ADMSCs transplantation may help accelerate oral ulcer healing, possibly through the induction of angiogenesis by VEGF and PDGF as well as epithelial and connective tissue proliferation as evidenced by increased EGF and collagen gene expression.

Prevalence and characteristics of non-syndromic orofacial clefts and the influence of consanguinity.

UNLABELLED: The Objective of this study was to identify the prevalence and describe the characteristics of non-syndromic orofacial cleft (NSOFC) in Jeddah, Saudi Arabia and examine the influence of consanguinity. STUDY DESIGN: Six hospitals were selected to represent Jeddah's five municipal districts. New born infants with NSOFC born between 1st of January 2010 to 31st of December 2011 were clinically examined and their number compared to the total number of infants born in these hospitals to calculate the prevalence of NSOFC types and sub-phenotypes. Referred Infants were included for the purpose of studying NSOFC characteristics and their relationship to consanguinity. Information on NSOFC infants was gathered through parents' interviews, infants 'files and patient examinations. RESULTS: Prospective surveillance of births resulted in identifying 37 NSOFC infants born between 1st of January 2010 to 31st of December 2011 giving a birth prevalence of 0.80/1000 living births. The total infants seen, including referred cases, were 79 children. Consanguinity among parents of cleft palate (CP) cases was statistically higher than that among cleft lip with or without cleft palate (CL/P) patients (P = 0.039). Although there appears to be a trend in the relationship between consanguinity and severity of CL/P sub-phenotype, it was not statistically significant (P = 0.248). CONCLUSIONS: Birth prevalence of NSOFC in Jeddah City was 0.8/1000 live births with CL/P: 0.68/1000 and CP: 0.13/1000. Both figures were low compared to the global birth prevalence (NSOFC: 1.25/1000, CL/P: 0.94/1000 and CP: 0.31/1000 live births). Consanguineous parents were statistically higher among CP cases than among other NSOFC phenotypes.

Assessment for the children's fear survey schedule-dental subscale.

OBJECTIVES: Child dental fear causes a significant management problem. The Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) is the most widely used measure of dental fear in children. This study was undertaken to develop and test reliability and validity for the Arabic version of the CFSS-DS. STUDY DESIGN: the English CFSS-DS was translated to Arabic language and its reliability and validity were evaluated by distributing it to 6-12 year old Arabic pediatric dental patients (n=220). Of whom 144 children were assigned for test- retest reliability. To test criterion validity; 44 children were subjected to behavior rating during treatment and compared with their CFSS-DS. Fear of returning to the dentist was evaluated for all the children to test construct validity. RESULTS: the Arabic version of the CFSS-DS showed good internal consistency (alpha = 0.86) and test-retest reliability (0.86, P<0.001). Treatment with or without local anesthesia did not affect the children's behavior or fear scores. Significant correlations were found between total fear scores and both Frankl rating scale (r=-0.54, p<0.001) and willingness to return to the dentist (r=0.50, p<0.001). CONCLUSION: the Arabic version of the CFSS-DS appears to be a reliable and valid method for evaluating child's dental fear in Arabic cultures.

Female youth health promotion model in primary health care: a community-based study in rural upper Egypt.

The health status of underprivileged young females is a global concern. This intervention study in rural Upper Egypt used an integrated approach to develop a model for primary care health promotion services to female adolescents. An initial household survey and focus group discussions identified the health problems of a sample of 671 adolescent women aged 12-20 years recruited from one village. Interventions included training courses for health care providers on relevant health topics and on client-provider interaction skills; community and local authority mobilization; and health education sessions and a special record system for the women. An increase was seen in the utilization of primary care services.

Nonpharmacologic intervention to reduce blood pressure in older patients with mild hypertension.

BACKGROUND: Although nonpharmacologic interventions are widely recommended in the therapy of high blood pressure in older adults, surprisingly little data exist to confirm the efficacy of these interventions in older persons. METHODS: We conducted a randomized, controlled clinical trial in persons aged 60 to 85 years with a diastolic blood pressure of 85 to 100 mm Hg. The experimental arm was a nonpharmacologic intervention combining weight reduction, sodium restriction, and increased physical activity. The nonpharmacologic intervention consisted of eight weekly group and two individual sessions during the intensive phase, followed by four monthly group sessions during the maintenance phase. The control group received no treatment during the study. Blood pressure was assessed by certified technicians (blinded to group assignment) using random zero sphygmomanometers. RESULTS: Of 56 participants randomized, 47 completed the entire 6-month trial (21 in the intervention group and 26 in the control group). Attendance at the intervention sessions was excellent. The intervention group lost more weight (-2.1 kg) over 6 months than the control group (+0.3 kg). Trends for decreasing 24-hour urine sodium excretion in both the intervention and control groups, with greater trend in the intervention group, were not statistically significant. The intervention group experienced more reduction in systolic and diastolic blood pressure than did the control group (mean differences between groups at 6 months, 4.2/4.9 mm Hg, respectively). CONCLUSIONS: Our data indicate that a nonpharmacologic intervention will lower systolic and diastolic blood pressure levels in older people with borderline or mild elevations of diastolic blood pressure.

Comparison of subjective ratings of function with observed functional ability of frail older persons.

BACKGROUND: Important clinical decisions often hinge on patients' functional status. Previous studies have shown disagreement among sources of ratings of patients' functional status. This study compared patient self-ratings, family member ratings, and physician ratings of patient function to performance-based functional testing criteria. METHODS: Five activities of daily living of 73 older patients were studied at admission to a rehabilitation unit following discharge from an acute care community hospital. Data were collected from patients, family members, and physicians and were compared with performance-based function testing. RESULTS: Patient ratings were significantly more accurate than physician ratings for walking, transferring, and telephoning. Patients were significantly more accurate than family members for rating walking and telephoning, but patients were not significantly more accurate than family members or physicians for rating eating or dressing. CONCLUSIONS: We conclude that decisions about patients' functional level should be based on performance testing. If performance testing is unavailable, patients' own ratings are most accurate, followed by family ratings. Physicians' ratings are least accurate.
