The Art of Liquid Face Lift (Dermal Fillers)Osama Moawad
Soft tissue fillers are flexible substances that can be injected into the skin to improve the appearance of fine lines and wrinkles, plump lips, fill hollow cheeks, repair various facial imperfections, improve scars, and elevate deep folds. Perhaps nothing is more gratifying for cosmetic patients than having an immediate correction of rhytides or scars as a result of the injection of a dermal filler The result is a smoother, more youthful appearance with minimal "downtime" and maximum safety. Prof. Moawad uses a variety of soft tissue fillers, including, hyaluronic acid, and autologous fat (one's own fat) among others. Since filler substances do not involve major surgery and are generally cost-effective, men and women are using these youth-enhancing techniques more than ever. With the increasing desire for people to achieve a more youthful appearance, the aging baby boomer population, and the increased demand for "lunch-time procedures," the pharmaceutical market has responded by providing the cosmetic surgeon with an increasing number of options to meet the demands of the cosmetic patient.
We are truly in an “era of injectables,” with access to a varied armamentarium of products that yield dramatic aesthetic results with minimal recovery downtime. From its first published mention as an aesthetic treatment for glabellar lines in 1992, the use of commercially available BoNT type A (BoNTA) has captivated healthcare professionals and lay people alike. The availability of newer BoNTA formulations, with more expected in the near future, poses an exciting opportunity for aesthetic practitioners to reach an ever expanding potential patient base and provide increasingly refined treatment

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
These lecture slides, by Dr Sidra Arshad, offer a quick overview of physiological basis of a normal electrocardiogram.
Learning objectives:
