Microbial Impacts on Pharma Products & Cross ContaminationSrinath Sasidharan
This document discusses microbial contamination and cross-contamination in pharmaceutical manufacturing. It defines cross-contamination as the presence of small quantities of other products manufactured in the same premises. The types of contamination are physical, chemical, and biological from sources like personnel, equipment, and environment. Cross-contamination can be minimized through personnel procedures, adequate facilities, closed production systems, cleaning validation, and proper air pressure differentials. Special attention needs to be given to prevent cross-contamination of beta-lactam drugs like penicillin which can cause allergic reactions in sensitive patients. FDA regulations require dedicated areas for their production to prevent sensitization issues. Personnel hygiene and housekeeping are important to control contamination.
Particles smaller than one micron are most important to eliminate because they make up 99% of the number of particles in your air and can be breathed deep into the lungs and AEROCIDE can do that

Breast cancer: Post menopausal endocrine therapyDr. Sumit KUMAR
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.
Summer is a time for fun in the sun, but the heat and humidity can also wreak havoc on your skin. From itchy rashes to unwanted pigmentation, several skin conditions become more prevalent during these warmer months.
DECLARATION OF HELSINKI - History and principlesanaghabharat01
This SlideShare presentation provides a comprehensive overview of the Declaration of Helsinki, a foundational document outlining ethical guidelines for conducting medical research involving human subjects.
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.
Are you looking for a long-lasting solution to your missing tooth?
Dental implants are the most common type of method for replacing the missing tooth. Unlike dentures or bridges, implants are surgically placed in the jawbone. In layman’s terms, a dental implant is similar to the natural root of the tooth. It offers a stable foundation for the artificial tooth giving it the look, feel, and function similar to the natural tooth.

3. Fundamental Principle Of Dental
I.A.Q.( Indoor Air Quality).
Environmental Surfaces
Contaminated patient care items and surfaces pose different degrees of risk for infection
transmission based on their location and potential to transmit pathogens. With regard to
environmental surfaces, the latest precautionary dental guidelines also provide a better
understanding of how to discriminate between the two categories of environmental
surfaces: clinical contact surfaces and housekeeping surfaces
Categories of Contaminated Environmental Surfaces
Category Definition Examples
Clinical contact Surfaces that are directly Dental unit surfaces, laboratory
contacted by contaminated equipment, reusable containers of
instruments, devices, hands, dental materials, drawer handles,
or gloves heavily used countertops, pens,
telephone handles, doorknobs
Housekeeping Surfaces that require regular Floors, walls, lightly used
cleaning to remove soil and countertops
dust but that rarely contact
dental personnel or patients
4. Environmental Decontamination In Dentistry
“A high level of general cleanliness must be maintained in dental surgery.
Working surfaces, bracket tables and countertops should be disinfected. The
use of sterilize-able trays or disposables are recommended. Floors, walls and
sinks must be routinely cleaned. All spilt blood or body fluids must be
attended to immediately.“
The phrase “risk of aerosols contamination“ means :
1. “General cleanliness”, “routinely cleaned” are not enough.
2. “Spilt blood and body fluids” might not be attended too immediately.
3. Aerosol dispersal is not completely prevented by Using high-volume
suction and dental dam.
4. How many of dental clinics follow the exact IAQ preventive instructions?
5. Air conditioners make the air dryer (higher risk of droplet nuclei formation
because of fluctuating humidity levels)
5. Why is I.A.Q important in a
dental environment?
The execution of dental work and the use of various chemical compounds leads to
exposure levels for dentists, staff and patients to a range of potentially harmful airborne
contaminants. Especially for dental staff this exposure to potentially harmful air pollutants
can be significantly higher than that of individuals in most indoor environments.
Microorganisms
The use of high-speed drills and ultrasonic scaling equipment generates fine droplets which
are light enough to stay airborne for hours. Bacteria and viruses, which are contained in
these micro-droplets, are easily inhaled and constitute a potential source of infection.
Mercury
Numerous studies show that dentists and their staff have higher than average levels of
inorganic mercury (Hg) in their blood and urine. Mercury vapours can be released by the
placement and the removal of amalgam fillings. They may also be released from indoor
surfaces, where they may have accumulated over years of usage.
Disinfectants
Chemical disinfectants in a dental environment are responsible for a generally unpleasant
odour. Some disinfectants may also cause irritation and may have a sensitising potential
especially for staff.

Abstract
The purpose of this work is to assess, both experimentally and theoretically the status of air quality in a dentistry clinic of the
Athens University Dentistry Faculty with respect to chemical pollutants and identify the indoor sources associated with dental
activities. Total VOCs, CO(2), PM(10), PM(2.5), NO(x) and SO(2) were measured over a period of approximately three months
in a selected dentistry clinic. High pollution levels during the operation hours regarding CO(2), total VOCs and
Particulate Matter were found, while in the non-working periods lower levels were recorded. On the contrary, NO(x) and
SO(2) remained at low levels for the whole experimental period. These conditions were associated with the number of
occupants, the nature of the dental clinical procedures, the materials used and the ventilation schemes, which lead to
high concentrations, far above the limits that are set by international organizations and concern human exposure. The indoor
environmental conditions were investigated using the Computational Fluid Dynamics (CFD) model PHOENICS for inert gases
simulation. The results revealed diagonal temperature stratification and low air velocities leading to pollution stratification,
accompanied by accumulation of inert gaseous species in certain areas of the room. Different schemes of natural ventilation
were also applied in order to examine their effect on the indoor comfort conditions for the occupants, in terms of air renewal and
double cross ventilation was found to be most effective. The relative contribution of the indoor sources, which are mainly
associated with indoor activities, was assessed by application of the Multi Chamber Indoor Air Quality Model (MIAQ) to the
experimental data. It was found that deposition onto indoor surfaces is an important removal mechanism while a great
amount of particulate matter emitted in the Clinic burdened severely the indoor air quality. The natural ventilation of the
room seemed to reduce the levels of the fine particles. The emission rates for the fine and coarse particulates were found to be
almost equal, while the coarse particles were found susceptible to deposition onto indoor surfaces.

7. The Dental I.A.Q. Solutions
Temporary Solutions:
Using of disinfectants on surfaces. (Time
consuming and costly )
Long-lasting preventive solutions :
Slow releasing active chemicals (Titanium
Dioxide, TiO2), air filters, UV-C light and
negative ions.
9. So what is IAQ ?
Indoor Air Quality as defined by OSHA Malaysia,
OSHA Singapore and ASHRAE standard 62-1989.
“Wherein it is stated that air in which there are
no known contaminants at harmful
concentrations”. So quality air is always related
to fresh air.
10. 3 main causes of IAQ problems
• Source of contamination
• Susceptible occupants
• Mechanism transport of contaminants
11. Type of IAQ contaminants
Gases
Volatile Organic Compounds (V.O.C).
Potential VOC’s come from gases of building furnishings i.e. carpets,
furniture etc. and life cycle byproducts of micro-organism that lives in
the building (or its HVAC system).
Aldehyde vapors are typical byproducts of both off gassing and
chemical processes, that occur inside or outside the building.
Particles
Mostly counted in the diameter range from 0.1 micron or greater.
Bio-aerosol are defined as airborne particles, which are living
organisms, spores and fragments of organisms released from living
organisms.
These include pathogens (disease causing viruses), fungi (mold) and
bacteria.
12. What I.A.Q problems should we be
concerned about?
1. How can people eject flu viruses into the air.
2. What different forms can airborne viruses take.
3. How far can those viruses travel & how can they
circulate within buildings and inside their HVAC
units.
4. What conditions increase airborne flu virus
survival.
5. What systems are available to sterilize, capture
and/or kill airborne flu viruses.
13. Airborne transmission depends on people to
launch viruses into the air. People can shed
this many flu virus into the air:
1. Coughing 3,000+
2. Sneezing 3,000+
3. Breathing 200+ natural sterilization , nose hair & mucus.
4. Talking/Singing 1,000+
5. Vomiting 1,000+
6. Diarrhea *20,000+
14. How far can Airborne Viruses Travel?
Large/Small Droplets Droplet Nuclei
1. Coughing 1-5 feet 160+ feet
2. Sneezing 8-15 feet 160+ feet
3. Singing, Talking 1-3 feet 160+ feet
4. Mouth Breathing 1-3 feet 160+ feet
5. Diarrhea* 5 feet+ 160+ feet
*As a result of toilet water aerosolization, air contamination in toilets
need to be effectively sterilized and contained.
17. Droplet Nuclei Viruses are 0.3μ or less, it can
penetrate deeply into the human lungs
A μm is a micron or 1/1,000,000 of a meter.
The smallest particle you can see is 30μm.
22. Optimum Humidity
For optimum air quality, Indoor Relative Humidity should always be
maintained between 40% and 60%!
23. Low indoor humidity increases
Droplet Nuclei Levels
• Viruses evaporate faster in low humidity levels
thus creating More Droplet Nuclei.
• Low humidity allows droplet nuclei to stay
airborne longer as the droplets do not absorb
water weight which would cause them to fall to
the ground.
• Indoor Air currents both created by HVAC
systems and people movement assure that
droplet nuclei will remain airborne Indefinitely.
• This allows HVAC systems to remove and
redistribute droplet nuclei throughout the
building to infect more occupants.
24. So, is there a solution to resolve
I.A.Q.A problem?
25. Yes!
According to Environmental Protection Agency
These are the recommended technologies
According to EPA guidelines…
1. MERV (Minimum Efficiency Reporting Value) Rated Filters
(H.E.P.A)
2. Germicidal UV Lights (UV-C)
3. Magnetized Air Media Filtration (ELECTROSTATIC FILTERS)
4. Bi-Polar Ionization (GERMICIDAL MEDICAL LAMP)
5. Photo-Catalytic Oxidation (NANO TiO2)
26. So in essence, if we follow all five sterilization recommended by
EPA, we would effectively have a 24/7 sterilization solution
protocol

filter
27. Lets explore and understand each of
the 5 technologies recommended by
Environmental Protection Agency
(EPA)
28. 1. MERV (Minimum Efficiency Reporting
Value) Rated Filters (H.E.P.A)
• Particulate matter contain pathogens (viruses,
bacteria and infectious organisms), allergens and
carcinogens.
• Mechanical air filters, like High Efficiency Particulate
Air (HEPA) filters, remove 99.97% of all airborne
particulates of 0.3 microns and above in size.
• They trap the particles in filters made out of tightly
woven fibers.
29. 2.Germicidal UV Lights (UV-C)
How does UV-C Work?
• UV-C light emits germicidal wavelengths
between 200-300nm. This reacts with the
DNA and permanently alters the structure and
the molecular bonds of microbiological
contaminants such as bacteria, viruses, germs,
molds and mildews.
30. Its scientifically proven that Ultraviolet Germicidal
lamps (UVC) working at 253.7 nanometers at the
correct intensity can effectively prevent cross
contamination of the following airborne diseases:-
• Aspergillosis Niger
• Legionella
• SARS
• Bacillus Anthracis
• Dust Mites
• Allergy & Sinusitis
• Tuberculosis (TB)
• H1N1
33. 3. Magnetized Air Media Filtration
(ELECTROSTATIC FILTERS)
• Electrostatic air precipitators use a process called
electrostatic attraction to trap charged particles.
• They draw air through an ionization section where
particles obtain an electrical charge.
• The charged particles then accumulate on a series of
Flat plates called collectors that are oppositely
charged.
34. 4. Bi-Polar Ionization (Medilites)
• Air ion generators, or ionizers disperse negatively charged ions
(anions) into the air, similar to the electronic air cleaners but
without a collector plate.
• These ions attach to airborne particles, making them heavier
and causing them to settle on the ground faster, away from
the nasal breathing zone.
• Negatively charged oxygen molecules will behave like hydroxyl
radicals to neutralize odors and destroy the DNA of pathogens
and allergens.
• Studies have shown that anions can freshen indoor air, reduce
tiredness, relieve stress, alleviate affective depression,
reinforce collagen, and strengthen the functions of autonomic
nerves and the immune system.
35. 5. Photo-Catalytic Oxidation
-NANO Titanium Dioxide (TiO2)
• Nano Titanium Dioxide (TiO2) transforms biological
and gaseous pollutants into harmless products by a
process called photo catalytic oxidation (PCO).
• When applied as a coating and exposed to ultra-
violet or ambient light, Nano-TiO2 produces hydroxyl
radicals and superoxide ions that will neutralize
biological and gaseous contaminants in indoor air.
36. • We now know IAQA problems exist!
• We now understand the
recommendations by EPA for effective
sterilization!
• So, what kind of equipments and
technologies does Soma Medical have to
resolve these IAQA problems?
37. Benefits
• Cost efficient
• Long lasting
• Low maintenance
• Good indoor air quality
44. The proof is in the pudding!!
Our recommended sterilization
solution protocol and products
can be effectively tested through a
pre and post microbial challenge
test, VOC count test and
particulate testing
45. Our equipments used for testing
Particle Scanner
Negative Ion Tester
IAQA VOC Tester
46. The importance of testing for
Volatile organic compounds (VOC)
Volatile organic compounds (VOCs) refers
to organic chemical compounds which have
significant vapor pressures and can affect the
environment and human health.
47. The importance of testing for
negative ions
Negative ions help freshen and purify the air by
neutralizing allergens such as pollen, mold
spores, dust, and animal dander floating in the
air. Negative ions will cause floating particulates
to be attracted and stick to each other, forming
'clumps', this eventually falls to the ground and
thus purifies the air.
48. The importance of testing for
Particulate count
Particle counters are used to determine the air
quality by counting and sizing the number of
particles in the air. This information is useful in
determining the concentration and micron size of
particulates since it has a direct relationship to
human well being and IAQA.
