Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent
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.

2. Price elasticity of demand
Price elasticity of demand is generally defined as the responsiveness or
sensitiveness of demand for a commodity to changes in its price. More
precisely, elasticity of demand is the percentage change in demand for a
commodity due to a one percent change in one of the independent variables.
The price-elasticity of demand for a product is thus the percentage change in
the quantity demanded that results from a one percent change in its price.
The formula for price elasticity of demand (PED) is
% change in quantity demanded
% change in price of the good
• So, if the price of osteopathy rose by 10% and the quantity bought fell by
5%, then the PED would be –5%/+10% = –0.5. This tells us that demand for
osteopathy is not particularly sensitive to changes in price. It is what
economists call price Inelastic.
3. Take another example, if the price of eye tests fell by 20%
and the quantity of eye tests bought rose by 30% then,
the value of PED would be +30%/–20% = –1.5. In this
case, the demand for eye tests is price elastic, i.e.
sensitive to changes in price. Notice several things
about PED.
• First, the value of PED is always negative reflecting the
inverse relationship between price and quantity
demanded.
• Second, PED is just a number; it is not expressed in
terms of any particular units. How do we know whether
demand is elastic or inelastic? The rule is: Demand is
price inelastic whenever the % change in price leads to
a smaller % change in quantity demanded. This gives
PED values between 0 and –1.
4. • Demand is price elastic whenever the % change in price leads to a
larger % change in quantity demanded. This gives PED values
between –1 and –infinity. Price elasticity of demand allows us to
predict what will happen to spending when price changes. Take the
example of the increase in the price of osteopathy used above. As the
price of osteopathy rises, people will buy fewer treatments, but will
they spend less?
Example 1: Suppose that the price of a treatment rose from 20 Birr an
hour to 22 Birr (a price increase of 10%). At 20 Birr an hour,
consumers were buying 1,000 treatments per week and spending
20,000 Birr. After the price rise they bought 950 a week (a fall of
5%), but their spending had risen to 20,900 Birr (= 950 x 22 Birr). So
the answer in this case is no. People spend more on osteopathy after
the price rise because the percentage increase in price is greater than
the percentage fall in sales volume. So although osteopaths sell fewer
treatments, the higher price of each treatment more than offsets the
lost quantity of treatments sold.
5. This gives us a general rule:
• If PED is inelastic; a rise in price will lead to people spending
more, while a fall in price will lead to people spending less.
• If PED is elastic, a rise in price will lead to people spending less,
while a fall in price will lead to people spending more.
• Price elasticity of demand allows economists to analyze and
predict the effect of changes in prices on different markets. We
can see an example of this by looking at the debate over cost
sharing in health care.
Example 2: Cost sharing is the term used to describe different
forms of direct charging for health care services. Increasingly,
direct charging is seen as a way of reducing demand, but also as
a way of raising revenue. How effective is this policy? For
instance, in Ethiopia, many people have to pay prescription
charges, which they have to pay a certain amount every time
they want to have a prescription dispensed
6. • What has been the effect of this charging? Estimates made by
Hughes and McGuire have indicated that demand for
prescriptions is rather price inelastic with a mean value of –0.32.
This would suggest that prescription charges would be an
effective way of raising revenue, but not have a great effect on
the level of demand.
• Hughes and McGuire calculated, for instance, that the rise in
prescription charges from 3.75 Birr in 1992 to 4.25Birr in 1993
would have resulted in the generation of estimated 17.3 million
Birr in extra revenue, but led to a fall of 2.3 million in the
number of prescriptions dispensed. However, their research also
suggests that demand for prescriptions is becoming more prices
elastic as time passes.
• They found that PED was – 0.125 in 1969, –0.22 in 1980, –0.68
in 1985 and –0.94 in 1991. This suggests that raising prescription
charges is now likely to raise less revenue, but lead to greater
reductions in use of prescribed medicines than it did in the past
7. 2. Income elasticity
The concept of elasticity can be applied to the impact of both income and
changes in the prices of other goods on quantity demanded. Income
elasticity of demand (YED) measures how demand reacts to changes in
income. The formula for income elasticity of demand is:
% change in quantity demanded
% change in income
If the result is positive, then the goods are normal, if it is negative then they
are inferior. All the evidence suggests that health care is not only a normal
good, but that it is income elastic, i.e. rising income leads to a greater %
rise in demand for health care. Obviously the formula for measuring
income elasticity of demand is the same as the formula for measuring the
price-elasticity. The only change in the formula is that the variable
‘income’ (y) has been substituted for the variable ‘price’ (p). Here,
income refers to the disposable income, i.e, income net of taxes.
8. • Unlike price-elasticity of demand, which is always negative,
income-elasticity of demand is always positive because of a
positive relationship between income and quantity of product
demanded. However, there is an exception to this rule. Income-
elasticity of demand for an inferior commodity is negative
because of the income substitution effect. The demand for
inferior goods decreases with increases in consumers’ income.
When income increases consumers switch over to the
consumption of superior commodities, i.e. they substitute
superior goods for inferior goods. For instance, when income
rises, people prefer to buy more meat and less potato.
9. Cross price elasticity of demand
(XED)
This measures how demand reacts to changes in the price of other
goods. Cross price elasticity of Demand = % change in
quantity demanded of main good and % change in price of other
good
• If cross price elasticity of demand is positive then this indicates
that the goods are substitutes.
• If it is negative, then the goods are complements.
Finally, the concept of elasticity can be applied to supply.
10. Price elasticity of supply (PES)
This measures how sensitive quantity supplied is to a change in the price of the good. The
formula for price elasticity of supply is:
% change in quantity supplied
% change in price of the good
Price elasticity of supply is always positive, reflecting the positive relationship between
price and quantity supplied. PES becomes more elastic over time. This reflects the time
it takes to switch resources into a market. For instance, in health care the PES is likely to
be fairly inelastic in the short run, but much more elastic in the long run. Even if price
raise significantly, it will take time for firms to react and to produce more health care.
For instance, to deliver more health care new hospitals will need to be built or existing
hospital extended and extra doctors and nurses will need to be trained. All of this takes
time. The concept of elasticity has helped to make our market theory more sophisticated.
However, the model still suffers from being rather static.
