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.

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!

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

Tom Selleck Health: A Comprehensive Look at the Iconic Actor’s Wellness Journeygreendigital
Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

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.
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. Transverse Myelitis
Definition:
• A pathogenically heterogeneous focal inflammatory
disorder of the spinal cord characterized by acute or sub
acute development of motor weakness, sensory
impairment, bowel or bladder dysfunction and autonomic
dysfunction.
• The term myelitis refers to inflammation of the spinal
cord; transverse simply describes the position of the
inflammation, that is, across the width of the spinal cord.
3. Epidemiology:
Incidence between 1-8 new cases per million per year.
Affects people of all ages, with a range of six months to
88 years.
Bimodal peaks between the ages of 10 to 19 years and
30 to 39 years.
There is no gender or familial association with TM.
It is estimated that about 1,400 new cases of
transverse myelitis are diagnosed each year in the
United States.
4. Transverse Myelitis
Etiology:
• Infectious
• Non Infectious inflammatory type
• Idiopathic
Infectious:
I. Viral:
A. Enter viruses (groups A and B Coxsackievirus, poliomyelitis, others)
B. Herpes zoster
C. Myelitis of AIDS
D. Epstein-Barr virus (EBV), cytomegalovirus (CMV), herpes simplex
E. Rabies
II. Bacterial/fungal/parasitic:
A. Mycoplasma pneumonia
B. Burrelia burdorferi ( Lyme disease)
C. Pyogenic myelitis 1.Acute epidural abscess and granuloma 2. Abscess of spinal cord
D. Tuberculous myelitis
E. Syphilitic myelitis
F. Parasitic and fungal infections producing epidural granuloma,
5. Transverse myelitis
Noninfectious inflammatory type:
Postvaccinal myelitis
Acute and chronic relapsing or progressive multiple
sclerosis (MS)
Subacute necrotizing myelitis and Devic’s disease(NMO)
Myelopathy with lupus or other forms of connective tissue
diseases
Para neoplastic myelopathy
Idiopathic :
Clinical events that are consistent with TM but that are not
associated with CSF abnormalities or abnormalities
detected on MRI and that have no identifiable underlying
cause are characterized as possible idiopathic TM.
6. Transverse Myelitis
IMMUNOPATHOGENESIS:
-pathologic heterogeneity with involvement of both
gray and white matter
-TM is not a pure demyelinating disorder but rather a
mixed inflammatory disorder that affects neurons,
axons, and oligodendrocytes and myelin.
-autopsy reports have described lymphocytic
infiltration with demyelination and axonal loss
-30 to 60 percent of the idiopathic TM cases, there is
an antecedent respiratory, gastrointestinal, or
systemic illness.
7. Transverse Myelitis
IMMUNOPATHOGENESIS:
-In parainfectious TM, the injury may be associated with direct
microbial infection of the central nervous system, or with the
systemic response to infection by a variety of agents such as
varicella zoster virus, herpes virus, and Listeria monocytogenes.
-Lupus-associated TM could be associated with central nervous
system vasculitis or thrombotic infarction of the spinal cord.
-TM can occur as part of the spectrum of multiple sclerosis
8. Transverse myelitis
Symptoms of TM typically develop rapidly over several
hours
Approximately 37 percent of patients worsen maximally
within 24 hours
Some cases worsen more slowly, over several weeks.
Clinical Presentation: 4 Symptom groups
Motor
Sensory
Autonomic
Pain
9. Transverse Myelitis
Motor:
Depends on level, lesion extent:
Examples:
C3-C5 Quadriplegia, Respiratory Paralysis( diaphragm)
T1-T2:Spastic paraplegia
L1-S5:UMN/LMN in lower extremities, Bowel/bladder dysfunction
(urinary retention)
Spinal shock: Sometimes in hyper acute stage( legs flaccid/areflexia);
then spasticity develops
Sensory:
Paraesthesias, numbness, altered temp sensations., etc.
L'hermitte sign (Paresthesias in the limbs, elicited by neck flexion)
10. Autonomic:
Urinary urgency, incontinence, nocturia, urine retention
Bowel: Urgency, incontinence, retention
Sexual Dysfunction
Pain:
“Burning” radicular pain
“Tight squeezing”
“banding” sensation
Note:
Severe cases of ascending myelitis involving the cervical spinal cord may
cause neurogenic respiratory failure.
Longitudinally extensive TM can produce hiccups due to involvement of the
medulla, and persistent nausea and vomiting due to involvement of the
area postrema
11. Diagnostic Criteria for Transverse Myelitis*
• Bilateral (not necessarily symmetric) sensorimotor and autonomic
spinal cord dysfunction.
• Clearly defined sensory level.
• Progression to nadir of clinical deficits between 4 hours and 21 days
after symptom onset
• Demonstration of spinal cord inflammation: cerebrospinal fluid
pleocytosis or elevated IgG index,† or MRI revealing a gadolinium-
enhancing cord lesion.
• Exclusion of compressive, post radiation, neoplastic, and vascular
causes.
* Clinical events that are consistent with transverse myelitis but that are
not associated with cerebrospinal fluid abnormalities or abnormalities
detected on MRI and that have no identifiable underlying cause are
categorized as possible idiopathic transverse myelitis.
12. Types:
Complete:
Usually longer (>3 vertebral segments) and Central--
>Symmetric decrease in motor/sensory functions associated
with decreased sphincter functions.
Incomplete:
Shorter( <3 vertebral segments), peripheral lesions involving
limited tracts, usually incomplete loss of function.
13. Classification based on spinal cord lesion characteristics:
Acute partial TM:
• Para infectious
• Asymmetric lesions typically of 1 or 2 vertebral segments in length
• Usually mild to moderate in severity
• High risk for MS when MRI brain reveals WM lesions compatible with
demyelination.
Longitudinally extensive TM:
• Asymmetric or symmetric spinal cord lesions that span ≥3 contiguous
vertebral segments.
• Usually moderate to very severe
• Most commonly associated with high risk for NMO spectrum disorders in
the setting of seropositivity for NMO- IgG
14.
15.
16. Diagnosis
Diagnosis of TM is based on clinical and Radiological findings
CSF studies:
Usually depends on etiology
Most commonly, Cerebrospinal fluid (CSF) is abnormal in half of patients,
with elevated protein level (usually 100 to 120 mg/100 mL) and moderate
lymphocytosis (usually <100/mm3). Glucose levels are normal. Oligoclonal
bands are usually not present in isolated TM, and when present suggest a
higher risk of subsequent MS.
Lab work up depends on suspected etiology.
Imaging:
Lesions may occur anywhere within the cord, however the thoracic cord is
the most frequently involved site.
CT Spine
• variable enlargement of the spinal cord
• variable contrast enhancement patterns (including no enhancement)
17. MRI Spine
• Up to 40% of cases have no findings on MRI. In the remainder, the
appearance is variable and non-specific.
• large variation in lesion size, however they most commonly extend for 3-4
spinal segments.
• lesions typically occupy greater than two thirds of the cross-sectional area of
the cord.
• variable enlargement of the spinal cord.
• an intrinsic spinal cord lesion that usually enhances with gadolinium
administration. It is critically important to exclude compressive lesions of the
spinal cord, such as spinal epidural abscess, that require specific treatment.
Typical signal characteristics on MRI brain include:
T1 : isointense or hypointense
T2 : poorly delineated hyperintense signal
T1 C+ (Gd) : variable enhancement patterns (none, diffuse, patchy,
peripheral)
18.

21.
22. Interpretation of clinical spinal cord syndromes
• Complete cord syndrome:
Loss of all motor and sensory modalities below the level
of the lesion
Associated with acute, severe, "necrotizing" myelitis.
• Brown-Sequard syndrome (partial or complete):
Dysfunction of the corticospinal tracts and dorsal
columns( symptoms ipsilateral to the lesion) and
spinothalamic tract dysfunction( symptoms contralateral
to the lesion)
• Conus-Medullaris syndrome:
Can be associated with Viral or post-viral myelitis
syndromes.
23.
24.
25.
26.
27. TM-PROGNOSIS
Most patients with idiopathic TM have at least a partial recovery, which
usually begins within one to three months.
Some degree of persistent disability is common, occurring in about 40
percent.
Significant recovery is unlikely if there is no improvement by three months.
A very rapid onset with complete paraplegia and spinal shock have been
associated with poorer outcomes.
TM is generally a monophasic illness. However, a small percentage of patients
may suffer a recurrence.
Cont………….
28. TM-PROGNOSIS(cont…
While patients are often treated with parenteral
corticosteroid therapy, there is limited evidence that this
approach alters outcomes.
MS is more likely to develop in those with partial and
asymmetric cord involvement versus a complete cord
syndrome. A finding of demyelinating lesions on brain MRI
also identifies those at higher risk for MS.
