This document summarizes potential toxic effects from ingredients commonly found in decorative cosmetics such as fragrances, heavy metals, parabens, and other chemicals. Fragrances like linalool and limonene can cause allergic reactions when oxidized. Heavy metals like lead, cadmium, and mercury may be present as impurities in pigments. Parabens are widely used preservatives that are absorbed through the skin and linked to health issues. Many ingredients in eye makeup, lipstick, nail polish and other cosmetics can cause issues like dermatitis, dry eye, reproductive toxicity and some are known carcinogens. Alternatives include using natural cosmetics and removing makeup before sleeping.

CONTROVERSIAL INGREDIENTS OF COSMETICS
Parabens are a set of chemicals which are extensively used as preservatives especially in cosmetics.
They can be discovered in shampoos, industrial moisturizers, shaving gels, topical/parental preparations, tanning solutions, toothpaste, and also in food additives.
Parabens are used to prevent microbial growth of the bacteria in cosmetics to maintain the customers health and maintain the integrity of the product.
Common parabens used are: methyl paraben, propyl paraben, ethyl paraben and butyl paraben.
Parabens will cause a range of reactions to those with allergies. They are notable to cause skin irritation and dermatitis, that could be a serious form of skin inflammation characterized by rashes, blisters and burning skin.
Parabens deeply penetrate the skin and disrupt the conventional functioning of hormones.
Dioxane
The compound 1,4-dioxane is a trace contaminant in some cosmetic products. It is not used as an ingredient in cosmetics, but may be present in extremely small amounts in some cosmetics.
1,4-dioxane forms as a byproduct during the manufacturing process of certain cosmetic ingredients.
These ingredients include certain detergents, foaming agents, emulsifiers, and solvents.
The compound is formed through a process called as ‘Ethyoxylation’, in which ethylene oxide, a known breast carcinogen is added to other chemicals to make them harsh.
Formaldehyde Liberators
Formaldehyde is a colorless, strong smelling gas used in a wide range of industries and products including building materials, cabinets furniture, walls and personal care products.
Formaldehyde and formaldehyde releasing preservatives are found in many personal care products, particularly in shampoos, liquid baby soaps, nail polish, nail glue, hair gel and etc.
DMDM Hydantoin
DMDM hydantoin is an organic compound belonging to a class of compounds known as hydantoins.
DMDM hydantoin works as a preservative because the released formaldehyde makes the environment less favourable to the microorganisms.
DMDM Hydantoin is found in lotion, sunscreen and make-up remover and is one of the least sensitizing of the FRPs.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

ABDOMINAL TRAUMA in pediatrics part one.drhasanrajab
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.
3. Linalool and limonene in fragrances
• Pure linalool is not allergenic or a very weak allergen, but autoxidizes on
air exposure and the oxidation products can cause contact allergy.
• Limonene is one of the most inexpensive fragrance materials.
• Limonene forms allergenic oxidation products during handling and
storage.
• The sensitizing potential of limonene increases with prolonged air
contact at room temperature: it is oxidized to allergenic derivatives.
4. Heavy metals impurities
• Press powder for eye shadow main ingredients are talc with
pigments and zinc or magnesium stearate used as a binder.
• A metallic brilliant finish is created by copper, aluminium,
brass, gold or silver powders.
• Heavy metals such as cadmium, copper and lead can be
retained as impurities in the pigments of eye shadows.
5. The most common heavy metals detected in
cosmetic products are:
• lead (Pb)
• cadmium (Cd)
• mercury (Hg)
• chromium (Cr)
• nickel (Ni)
• copper (Cu)
Heavy metals can be found in:
• shampoo
• lipstick
• cream
• eye shadow
• powder
6. Health effects
Fragrances and preservatives are the two most clinically
relevant allergens found in cosmetic products: contact allergy.
Fragrances account for 30–45% of allergic reactions to
cosmetics.
9. Parabens
The average daily total personal paraben exposure is
estimated to be 76 mg:
•cosmetics and personal care products: 50 mg
•pharmaceutical products: 25 mg
•food: 1 mg
10. Parabens
• Parabens applied to the skin are metabolized by keratinocyte
carboxylesterases and the conjugated metabolites are excreted in
urine and bile.
• Oral or intravenous parabens are metabolized by esterases within the
intestine and liver.
• Parabens have been detected in urine, serum, breast milk and
seminal fluid.
• Detection of parabens in breast tissue from patients with breast
cancer can be associated with application of deodorants.
11. Parabens
• Parabens bind human estrogen receptors with affinities 10000 to
1000000 times less than estradiol.
• The estrogenic activity of parabens may promote breast cancer
development.
• In men, fertility problems including low sperm count and decreased
motility might be associated with parabens.
13. False eyelashes side effects:
• traction alopecia (loss of eyelashes)
• allergic reactions
• infection (conjunctivitis, infection of eyelid)
• dry eye (more dust and air hits the eye with false
eyelashes)
15. Carbon black
Carbon black is a powder found in
eyeliner, mascara, eye shadow and
eyebrow shadow. It has been linked to
cancer and organ system toxicity.
17. Benzalkonium chloride (BAK)
• It is a preservative found in eyeliner, mascara and makeup
remover.
• BAK is toxic to the epithelial cells of the eyes.
• Epithelial cells keep dust, water and bacteria out of the eye
and provide a smooth surface on the cornea to absorb and
distribute oxygen and cell nutrients from tears to the rest of
the cornea.
18. Prime yellow carnauba wax
It is used in mascara and eyeliners to stiffen the
product and make them waterproof.
Prime yellow carnauba wax clogs the oil glands
in the eyes and can lead to dry eye disease.
20. Parabens
• Parabens are preservatives that are used to prevent the growth of bacteria in
makeup products.
• Parabens are absorbed through the skin and easily transmitted into the
bloodstream.
• They are endocrine disruptors and are linked to reproductive toxicity, early
puberty and breast cancer.
• Parabens can also make dry eye worse since they prohibit the oil glands that
line the eyelid from secreting enough oil (O’Dell).
22. Retinyl acetate or retinyl palmitate
• Two forms of vitamin A, can cause dry eye disease.
• They have been linked to cancer and reproductive toxicity.
• They are also found in anti-aging face creams and eye creams.
• There are well-documented studies that show that retinyl
acetate and palmitate will kill the oil glands and once they are
gone, you can’t rebuild them (O’Dell).
23. Heavy metals
• Nickel and chrome are two heavy metals found in all types of makeup,
especially in green or metallic shadows, as well as makeup brushes, even
the expensive types (O’Dell).
• Heavy metals are neurotoxins that have been linked to brain damage.
• Nickel in particular has been associated with lung cancer and respiratory
concerns.
• 17% of women have a nickel allergy, which can cause dry, itchy eyelids, a
red skin rash and watery blisters.
24. Titanium dioxide
Typically found in sunscreen.
Titanium dioxide is safe but when it is in powder form,
it can be problematic and is also a possible carcinogen.
26. Lead
• Lead is the commonly found harmful content in lipsticks.
• It mainly affects the nervous system and harms the hormonal
system.
• Lipsticks are known to cause allergy and irritation over the lips
and the surrounding skin.
• Other harmful effects include blockage of pores, drying and
chapping of lips.
27. Lipstick pigments
Lipstick pigments contain harsh chemicals
that irritate the skin and lead to blackening
of lips or they cause leucoderma due to
melanocyte destruction.
29. Other toxic elements in lipstick
• Toxic heavy metals: lead, cadmium, mercury and antimony.
• Lipsticks may contain formaldehyde (known carcinogen),
mineral oil substances (block pores) and parabens
(carcinogens).
• Lipstick manufacturers are also using harmful petrochemicals
to produce such lip formulas.
31. Toxic trio
• Toluene is a commonly used solvent that creates a smooth finish across
the nail and keeps the pigment from separating in the bottle.
• It can affect the central nervous system and cause reproductive harm.
• Formaldehyde (carcinogen) is used as a nail-hardening agent and
disinfectant for nail care tools.
• Exposure to dibutyl phthalate (added to polishes to provide flexibility)
has been linked to reproductive problems.
32. Healthy tips
• use of decorative cosmetics moderately (not every day if possible)
• removal of the makeup (especially before night)
• natural cosmetics (not perfect, but better)
• avoid waterproof cosmetics for everyday makeup (only for special
occasions)
• nurish skin every day
