Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
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.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.

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.

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.

18. FINE NEEDLE ASPIRATION BIOPSY
MOST IMPORTANT DIAGNOSTIC TOOL. SAFE AND MINIMALLY INVASIVE
ULTRASONOGRAPHIC GUIDANCE INCREASES THE ACCURACY OF FNAB
• Indicated if:
• Palpation-guided FNAC non-diagnostic
• Complex (solid/cystic) nodule
• Palpable small nodule (<1.5 cm)
• Impalpable nodule
• Abnormal cervical nodes
• Nodule with suspicious US features
GHARIB AND GOELLNER (1993) FOUND THAT
69% OF FNAB RESULTS WERE BENIGN,
4% WERE MALIGNANT,
10% WERE INDETERMINATE, AND
17% WERE NONDIAGNOSTIC.
SENSITIVITY 83%
SPECIFICITY 92%
FALSE-POSITIVE RATE WAS 2.9%, AND THEIR FALSE-NEGATIVE RATE WAS 5.2%.
20. FINE NEEDLE ASPIRATION BIOPSY
COMPLICATIONS
1. MINOR HEMATOMA AND ECCHYMOSIS MOST COMMON
2. PUNCTURE OF THE TRACHEA, CAROTID ARTERY, OR JUGULAR VEIN MAY
OCCUR
• CAN BE MANAGED BY APPLYING LOCAL PRESSURE
21. FINE NEEDLE ASPIRATION BIOPSY
Limitation
Difficult to differentiate between follicular adenoma and carcinoma on
cytology as it depends upon capsular and angioinvasion
Options in follicular carcinoma
Frozen section biopsy
Unilateral lobectomy
True cut biopsy
Danger of hemorrhage and injury to trachea, recurrent laryngeal
nerve and vessels
23. LABORATORY INVESTIGATIONS
• Serum TSH levels
• Low level suggests
autonomously functioning
nodule (usually benign)
• Doesn’t rule out malignancy
• Serum calcitonin levels
• Highly suggestive of MTC if
increased
• More sensitive marker than
CEA
• PCR assays for germline
mutations in the RET proto-
oncogene
• Diagnostic in Familial
medullary thyroid
carcinoma
• Pentagastrin-stimulated
calcitonin
• Used as tumour markers to
monitor patients who have
been treated for MTC
• Serum thyroglobulin levels
• Cannot differentiate
between benign and
malignant disease
• Used in patients who
underwent total
thyroidectomy * for thyroid
cancer
• Patients undergoing non
operative management of
thyroid nodule
• * increased levels indicate
recurrence
• Urinary VMA, metanephrine
and catecholamine
• To rule out coexisting
Pheochromocytoma in MTC
• Serum levels of CEA
• Increased in MTC but
nonspecific
• Better indicator of
prognosis than Calcitonin
• New patients with MTC should
be screened for RET point
mutations, Pheochromocytoma
and HPT.
24. Range of tests available
TSH - In most situations TSH analysed using a high sensitivity assay is now accepted as the first line test for assessment of
thyroid function. A TSH between 0.4 and 4.0 mIU/L gives 99% exclusion of hypo- or hyperthyroidism,12 while the TSH is
considered more sensitive than FT4 to alterations of thyroid status in patients with primary thyroid disease.
FT4 - This test measures the metabolically active, unbound portion of T4. Measurement of FT4 eliminates the majority of
protein binding errors associated with measurement of the outdated total T4, in particular the effects of oestrogen.
FT3 - FT3 has little specificity or sensitivity for diagnosing hypothyroidism and adds little diagnostic information. The main
value of FT3 is in the evaluation of the 2 to 5% of patients who are clinically hyperthyroid, but have normal FT4. In this
situation, an elevated FT3 would be suggestive of T3 toxicosis, in which the thyroid secretes increased amount of T3 or there
is excessive conversion of T4 to T3.
Thyroglobulin – Levels are increased in all types of thyrotoxicosis, except thyrotoxicosis factita caused by self-administration
of thyroid hormone. The main role for thyroglobulin is in the follow-up of thyroid cancer patients. After total thyroidectomy
and radioablation, thyroglobulin levels should be undetectable; measurable levels (>1 to 2ng/mL) suggest incomplete
ablation or recurrent cancer.
25. Thyroid autoantibodies – The key reason for the measurement of these antibodies is almost entirely for the management
of those with abnormal thyroid function. Autoimmune thyroid disease is detected most easily by measuring
circulating antibodies against thyroid peroxidase and thyroglobulin (Thyroid peroxidase antibodies are also known as
anti-TPO or anti-microsomal antibodies). In subclinical disease, the presence of thyroid antibodies increases the long-
term risk of progression to clinically significant thyroid disease about two-fold. Almost all patients with autoimmune
hypothyroidism and up to 80% of those with Graves’ disease have TPO antibodies, usually at high levels, although
about 5 to 15% of euthyroid women and up to 2% of euthyroid men will also have thyroid antibodies.
Thyroid stimulating antibody - (Previously called long-acting thyroid stimulating antibodies or LATS) has a role in the
diagnosis of Graves disease where other test results are ambiguous. It may also be useful in pregnant women with
Graves disease, to determine the likelihood of fetal thyrotoxicosis.
