Introduction: Herbal medicine is a medical system based on the utilization of plants or plant extracts for therapy. The continual increase in global consumption and the trade of herbal medicine has raised safety concerns in many regions. These concerns are mainly linked to microbial contamination, which could spread infections with multi-resistant bacteria in the community, and heavy metal contamination that may lead to cancers or internal organs’ toxicity. Methods: This study was performed using an experimental design. A total of 47 samples, herbal medicine products sold in local stores in Qassim region, were used in the experiments. They were tested for bacterial contamination, alongside 32 samples for heavy metal analysis. Bacterial contamination was determined by the streak plate method and further processed to determine their antimicrobial susceptibility patterns using MicroScan WalkAway96 pulse; heavy metals were determined using a spectrometer instrument. Results: A total of 58 microorganisms were isolated. All samples were found to be contaminated with at least one organism except three samples. The majority of the isolated bacterial species were gram negative bacteria, such as Klebsiella spp., Pseudomonas spp. and E. coli., which could be of fecal origin and may lead to pneumonia, skin, or internal infections. Furthermore, most of the gram-positive bacteria were found to be multi-drug resistant. Moreover, for heavy metals, all samples had levels exceeding the regulatory limits. Conclusion: This study demonstrated the presence of bacteria and heavy metals in samples of herbal medicines. Using these contaminated products may spread resistant infections, metal toxicities, or even cancers in the community.

BACKGROUND: Treating infraorbital dark circles is one of the commonest aesthetic demands worldwide. Autologous fat transfer is commonly used to treat dark circles by filling the grooves, without effect on skin quality. Platelet-rich plasma has been reported to improve skin quality. Autologous fat can be emulsified and filtered to produce nanofat, which is then injected superficially in the dark circles to improve skin quality and discoloration. OBJECTIVE: To compare the efficacy of platelet-rich plasma versus combined fat transfer and nanofat in treating infraorbital dark circles. MATERIALS AND METHODS: 30 patients with infraorbital dark circles of combined etiological factors were randomized into 2 equal groups: Group A treated with platelet-rich plasma and Group B treated with autologous fat transfer with emulsified fat injection. RESULTS: Excellent and moderate responses were observed in 3 (20%) and 2 (13%) patients in group A versus 7 (46.7%) and 4 (27%) in group B, respectively. Nonresponders were 8 (53.3%) in group A and only 1 patient (6.7%) in group B. The difference was statistically significant regarding improvement (p = .048) and patient satisfaction (p = .032). CONCLUSION: Autologous fat transfer with nanofat is significantly superior to platelet-rich plasma in improvement and satisfaction.

Introduction: Over the last few decades, use of complementary and alternative medicine (CAM) has grown in popularity, changing health professionals’ knowledge and attitude toward CAM, and the treatment recommended by them. The aim of the study was to evaluate the perception and practice of CAM among healthcare professionals. Methodology: A cross-sectional study was conducted among healthcare providers selected by multistage random sampling technique in two governmental hospitals and ten primary healthcare centers in two governorates in the Qassim region, Saudi Arabia. A web-based, self-administered questionnaire was distributed via social media platforms. Results: A total of 350 physicians responded to the survey. Good basic knowledge about CAM was reported by 48.6% of the respondents; a positive attitude was adopted by 53%; and CAM was actively practiced by 9.7%. Being a physician > 40 years and consultant affiliation were significantly associated with higher knowledge level about CAM (p = 0.006 and 0.03, respectively), as well as having a proactive practice (p = 0.007 and 0.04, respectively). Practicing CAM was prevalent among non-Saudi and married physicians (p = 0.02 for both). Knowledge about CAM and its practice were strongly correlated (p = 0.007). The most frequent constraints facing CAM practice were lack of knowledge and training on CAM (81.4%) and lack of studies supporting CAM (74.3%). Conclusions: The practices of health professionals in Qassim region need to be improved despite their expertise and favourable perception of CAM. Educational interventions could play greater roles in providing evidence-based CAM knowledge and enhancing training for physicians.
