Gingival mesenchymal stem cells as an alternative source to bone marrow mesenchymal stem cells in regeneration of bone defects: In vivo study.

Healing of critical sized bone defects represents a challenging issue in clinical and research fields. Current therapeutic techniques, such as bone grafts or bone grafts substitutes, still have limitations and drawbacks. Therefore, stem cell-based therapy provides a prospective approach to enhance bone regeneration.

Clinical outcomes are associated with changes in ultrasonographic structural appearance after platelet-rich plasma treatment for knee osteoarthritis.

Background: Hyaluronic acid (HA) and platelet-rich plasma (PRP) are two treatment options used for knee osteoarthritis (KOA) but studies comparing the efficacy of the two yield conflicting results. In addition, the association of clinical outcomes of PRP intra-articular injections with changes in the ultrasonography structural appearance of the knee has not been investigated.

Aim: To compare the efficacy of PRP and HA intra-articular injections as mono-therapeutic options for primary KOA, and to determine whether the clinical outcomes are associated with changes in the ultrasonography structural appearance.

Seroprevalence of antibodies against varicella zoster virus and rubella virus among newly recruited expatriate healthcare workers: a cross-sectional study.

Objectives: To assess the state of immunity to varicella zoster virus (VZV) and rubella virus (RV) among newly recruited healthcare workers (HCWs) in Kuwait before they begin work, and to determine whether there are differences in the prevalence of seronegativity according to nationality, gender, age group and occupation group.

Setting: This cross-sectional study involved analysis of blood samples from workers newly recruited to the Kuwaiti healthcare system.

Participants: All new non- national HCWs recruited during the study period (n=1540).

Determinants of Adherence with Malaria Chemoprophylactic Drugs Used in a Traveler's Health Clinic.

Background. The WHO recommends mefloquine, atovaquone/proguanil, and doxycycline for malaria chemoprophylaxis. Adherence to a drug is determined by many factors.

Travel risk behaviors as a determinants of receiving pre-travel health consultation and prevention.

Background: An estimated 30-60 % of travelers experience an illness while traveling. The incidence of travel-related illness can be reduced by preventive measures such as those provided by the Traveler Health Clinic (THC) in Kuwait.

Methods: The present study is an analytical comparative study between groups of travelers visiting the THC during the study period (May 2009 - December 2010) and an age- and gender-matched control group of non-visitors (800 people).

Prevalence of obesity among adolescents (10 to 14 years) in Kuwait.

The purpose of this cross-sectional study was to find out the prevalence of obesity and overweight among intermediate school adolescents aged 10 to 14 years. The study comprised a multistage stratified random sample that included 5402 children (2657 males and 2745 females). They represent 12.

Condom use among males (15-49 years) in Lower Egypt: knowledge, attitudes and patterns of use.

We conducted a cross-sectional study on a randomly selected sample of 2304 males aged 15-49 years from 4 governorates in Lower Egypt to assess their condom use and knowledge and attitudes towards condom use. Condoms were considered an effective method of contraception and prevention of transmission of sexually transmitted infections (STIs) by 60.5% and 60.
