Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
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
New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

2. CASE
• A 72-year-old male presented with ten days history of altered sensorium,
involuntary movement of limbs, and progressive dementia. There was no
history of fever or vomiting. On examination, the patient was disoriented,
the muscle tone was increased, and tendon reflexes were exaggerated. The
Babinski's sign was positive bilaterally. There were no signs of meningeal
irritation or cerebellar signs. The EEG was normal..
3. CREUTZFELDT-JAKOB DISEASE
• CJD is a transmissible, rapidly progressive, invariably fatal
neurodegenerative disorder...
• It is caused by the accumulation of abnormal prion protein in the neurons
resulting in their spongiform degeneration...
• MRI, especially the DWI sequence, plays a vital role in suggesting an early
diagnosis...
• It characteristically shows symmetrical T2 hyperintensities with restricted
diffusion in bilateral cerebral cortices and basal ganglia...
4. CREUTZFELDT-JAKOB DISEASE
• Confirmation of the disease requires demonstration of periodic sharp wave
complexes on EEG or 14-3-3 protein in CSF...
• The disease is transmissible and early diagnosis is helpful in appropriate
patient management...
• The disease is fatal and no treatment is currently available.
5. • Diffusion weighted MRI sequence (A and B) shows symmetrical
hyperintensity involving bilateral caudate nucleus, globus pallidus,
putamen, and cerebral cortex (arrows). The FLAIR image (C) also
shows diffuse hyperintensity involving the cerebral cortices and basal
ganglia (arrows)
6. MRI hyper intensities in familial CJD. The figure shows scans from
three different patients with different mutations in PRNP. White arrows show
lesions with high signal intensity.
7. • MRI shows symmetrical hyperintensities in the putamen and caudate
head within two months seen on T2-weighted and FLAIR
15. • MRI shows subtle abnormal signal intensity in the basal ganglion,
particularly evident within the caudate nucleus.
• The basal ganglia are hyperintense on DWI (not shown, but hypointense on
ADC) & slightly hyperintense on T2. As mentioned previously, this is more
evident with regard to the caudate nucleus. There is no abnormal cortical
signal or diffusion restriction.
16. TAKE HOME MESSAGE
• MR Imaging particularly diffusion weighted imaging is highly
sensitive in diagnosis of Creutzfeldt-Jakob disease.
• Typical features are
• Hyperintense signals in basal ganglia
• Thalami
• Cerebral cortices
MRI done as a part of routine checkup showed diffuse hyperintensity in the cortex of bilateral frontal and parietal lobes and in bilateral caudate nuclei, globus pallidi, and putamina on diffusion weighted [DWI; Figure 1A and Figure 1B] and fluid-attenuated inversion recovery (FLAIR) images [Figure 1C] with restriction of diffusion. Imaging appearance was typical for CJD in the clinical setting. Subsequent CSF analysis for 14-3-3 protein was positive, confirming the diagnosis

Creutzfeldt-Jakob disease (CJD) is the most common member of a group of diseases called human transmissible spongiform encephalopathies (TSEs). Spongiform means that when viewed under a microcsope, a brain specimen from a CJD patient looks like a sponge (see photo below on right). Encephalopathy is a broadly defined term that means abnormal brain structure or function. Transmissable means that these diseases are contagious. However, they cannot be passed from one person to another through the air, by touching, or through other forms of casual contact. See the section on Transmission below for more information. TSEs are progressive disorders, which means that they get worse with time.
Other members of the TSE group include Gertstmann-Sträussler-Scheinker disease (humans), kuru (humans), fatal familial insomnia (humans), scrapie (sheep, goats and mouflon), transmissible encephalopathy (mink), chronic wasting disease (deer and elk), and bovine spongiform encephalopathy (cows; BSE).
As a group, prion disorders are extremely rare, with a major study of 11 countries around the world finding 1.67 annual deaths per million people (1). The same study found that deaths from CJD were 1.39 per million, which highlights the fact that CJD is the most common member of the group.
