Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
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.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

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.

Life span of transfused RBCs is 50-60 days
Reports not available
Anemic At Birth requiring transfusion ? No perinatal bleed
Acquired causes: 70%
Congenital 30%
Infection:
Idiopathic – 80 percent
●Post-hepatitis – 9 percent
●Post-viral infection – 7 percent
●Drugs, other toxins – 4 percent
Intrinsic: Congenital /inherited: genetic disorders with pancytopenia as one of the manifestations
Initial battery of labs were collected including limited septic workup blood and urine.
Markers for infection / inflammation,
70ml over 4 hours
Malignancy/infiltrative bone marrow diseases : ALL, AML
To Examine for Blast cells in Peripheral Blood and clues to other causes of pancytopenia
Blood film will take time, so until results comes back, lets see what other tests can be sent at this time
May reveal enlarged medistinial shadows ( thymoma and metastatic infiltrations , leukemias)
His platelet count is low , and pancytopenic, if coagulation system is disturbed he may or even may be bleeding
Or Coagulation Defect leading that resulted in bleeding
We must do Coagulation profile and look for body organs that
Brain(Disturbed consciousness, USS brain) , Chest (CXR, Respiratory distress), Abdomen( distention , USS Abdomen) , Thigh (obvious)
Liver enzymes are elevated in many viral induced pancytopenia which isn’t the case
No liver dysfunction
Normal coagulation studies
NO factors which would predispose him to bleed
Causes : Acquired: 70% pancytopenia
The test we do will represent the differential diagnosis we want to RULE OUT
Culture take 12-24h hours to release report
Traumatic, rbcs are high but wbcs normal
CSF WBC Correction in Blood Contaminated CSF: it to be insignificant
CSF: rbc’s? traumatic
Enterovirus is a relatively uncommon cause of pancytopenia
Moreover respiratory viral agents if cause bicytopenia its mostly low wbc, and low plts, not common to see anemia
Cytopenia was shown to resolve median 12 days (7-28) after the onset of symptoms
references
Circle: blood transfusion given
5 days of symptoms

Reactive: nucleus is coarse, deep blue and can have rather plenty of cytoplam
Leukemia
Hematophagocytic Lymphohistiocytosis
Myelofibrosis
Myelodysplasia
Schistocytes may be artefacts, but is reported only when it is >1% ( significant) can normally be seen in neonates, with infection , for it be significant it should correlate with other features such findings of hemolysis , uremia
There is no hard and fast rule towards proceeding to Bone Marrow Biopsy, You may rule out inherited pancytopenia if there are pathognomic physical features , BMA may be done while considering IP, As most of the inherited pancytopenias would required BMA as a workup study
Hypocellular: Aplastic anemia which can be because of Inherited or acquired depending on history and PE
Hypercellular: Acute leukemia Blast cells ; lymphoblast for ALL and myeloblast for AML
Non- specific hypercellularity without blasts cell in case of peripheral destruction which is in case of overwhelming infection periphraly, SLE, Evans Syndrome
Infiltration: Gaucher cells, Foam cells, hematophagocytes
Normal Cellular: it may not be normal because there are less peripherally , it should be atleast hypercellular to indicate it is working normally
Leukocyte, Platelet, Lymphocyte: normal in morphology
Erythrocyte: Dysplastic megaloblastic
Normal M?E ratio is 2:1 to 4:1, in case of infection it increases to 6:1, and leukemia 25:1
Hematogones are benign lymphoid progenitor cells in pediatric especially preterm infants
Normal M?E ratio is 2:1 to 4:1, in case of infection it increases to 6:1, and leukemia 25:1

Liver: almostall types have hepatosplenomegaly
Neurologic; Mental retardation , seizures, ocular abnormalities
Gaucher Cells: Large blue round cells wrinkled appearance
Causes : Acquired: 70% pancytopenia
We had done a flow cytometric Analysis with the bone marrow study
Flow cytometry done along with bone marrow aspiration
As part of the screening for low WBC count , B and T lymphocyte was sent, can we send immunogloulins at this stage no as the baby is still too small and have maternal immunoglobulin which start weaning off by 2 – 6 months
A unique combination, was not found to be part of any textbook syndromes
Viral suppression or intrinsic pancytopenia
Follow up was done over several weeks and he persisted to have pancytopenia , giving clue that the cause is rather persistent and possibly intrinsic bone marrow.
At these stages he required irradiated blood transfusion given approximately 4 times
The serial B lymphocyte levels persisted to be low confirming the initial result, and that it isn’t of transient nature.
Initially low immunoglobulins confirmed on repeat evaluation of study 2 & 3 months of age and they were consistent with b – lymphocyte deficiency
We did Literature search for novel combination and found it is extremely unique and the closest similar case is: SIFD
And still it was similar in the Presentation Of severe congenital anemia , B cell immunodeficiency B-cell lymphopenia and panhypogammaglobulinemia
but dissimilar in many other context : neurologic degenerative features: Seizures, developmental delay or periodic fever (without infective cause)
They repeated similar tests and repeated bone marrow where the found hypocellular bone marrow. No other test was confirmatory. They did genomic testing which should a rather novel mutation.5 months
Bone marrow:
most prominent in the erythroid precursors but also the white blood cells and a little in megakaryopoiesis
MYSM1 short for Myb-like, SWIRM, and MPN domains-containing protein 1” gene Hematopoiesis
In Germany tests were repeated which were inconclusive they repeated Bone marrow and performed complete genomic sequencing
Homozygous,
Plan was devised in association with Doctors in Germany that he would need supportive care in the mean while:
For transfusion of PRBC, Irradiated, leukoreduced,
Immunoglobulin infusion depencing on his IgG Levels
IVIG: depending on his IgG-levels
Filgrastim: if his neutrophil leukocytes are below 500/µl. G-CSF is a growth factor for neutrophil granulocytes which are important for preventing bacterial infections.
He had required few admissions after travel for fever and neutropenia but remained stable and non of them were severe due to supportive care
HSCT: It was concluded that his bone marrow function will continue to decline, and that he would need a “new” healthy bone marrow, to cure him from the disease
Currently he has done HLA typing with his siblings , it has been fully matched with his sister, he is already being prepared for possible BMT in USA
