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!
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
Couples presenting to the infertility clinic- Do they really have infertility...Sujoy Dasgupta
Dr Sujoy Dasgupta presented the study on "Couples presenting to the infertility clinic- Do they really have infertility? – The unexplored stories of non-consummation" in the 13th Congress of the Asia Pacific Initiative on Reproduction (ASPIRE 2024) at Manila on 24 May, 2024.
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.

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
2. what is granuloma???
Granuloma is a focus of chronic inflammation
consisting of a microscopic aggregation of
macrophages that are transformed into
epithelium-like cells, surrounded by the collar of
mononuclear leukocytes, principally lymphocyte
& occasionally plasma cells.
6. Clinical features
Atrophic stage – The features resemble that
of atrophic rhinitis, including crust formation
and a foul smelling discharge.
(Carpenter’s Glue)
Granulation / nodular stage – (Sub dermal
infiltration)
Nodules are non ulcerative in nature.
These nodes are initially bluish red and
rubbery and upper lip giving a “woody” feel
Hebra nose-expansion of the anterior
nares and deformity of the upper lip
7. Cicatrizising stage – Adhesions and scarring is a feature
of this stage.
Stenosis distort normal nasal anatomy.
Shape of the nose changes and is classically name the
Tapir’s nose.
There may be glottic stenosis with respiratory distress.
8. Accumulated inflammatory cells include: Plasma cells, lymphocytes, eosinophils and
scattered large foam cells (Mikulicz cells) & Russell bodies.
Mikulicz cells- identified morphologically as a macrophage, not a plasma cell.
These foam cells have a central nucleus and a vacuolated cytoplasm containing
bacillli.
Russell bodies-Homogenous eosinophillic inclusion bodies found in plasma cells.
9. Investigations
Levin test – complement fixation test based on reaction of
patient’s serum with suspensions of K. Rhinoscleromatis High
titres of antibodies to K. rhinoscleromatis has been
demonstrated in these individuals
Tissue biopsy is diagnostic
CT-
10. Treatment
Usually self limiting course of its own accord ending in the
cicatrizing stage
Traditionally Used : streptomycin (1gm i.m) and tetracycline (2
g/day) for 4-6wks,
Recently used :
Oral rifampicin (450mg for a period of 6 weeks),
sulphamethoxazole-trimethoprim combination, and ciprofloxacin.
Local application of 2 % acriflavin for a period of 8 weeks has been
noted to be both efficacious and nontoxic.
Intralesional steroids have been tried.
11. Kailasa Regime :
Carbolic acid (0.2ml) + Glacial acetic acid (0.2ml) + Glycerine (0.4ml) +
10ml distilled water is injected locally as 1 to 2 ml twice weekly at
multiple sites of the lesion.
Usually 8-10 injections lead to complete regression of granuloma and
restoration of normal nasal patency.
S/E-chemical necrosis of granuloma.
Irradiation
- Total dose of 3000-3500 Gy over three weeks
12. Syphillis

13. Hereditary/congenital syphilis
Any of lesions of secondary and tertiary forms of syphilis of
nose may occur
In infants- snuffles most common
First appears as simple catarrhal rhinitis, then becomes
purulent with secondary fissuring and excoriation of nasal
vestibule and upper lip.
Obstruction may interfere with suckling and nutrition.
Gummatous and destructive lesions occur at puberty.
14. • Bulging of the frontal bones and
depression of the nasal bridge ("saddle
nose"), both due to periostitis
• Rhinitis from weeping nasal mucosal
lesions ("snuffles")

Secondary syphilis rarely recognized in the nose, as
mucous patches hardly ever occur on such a thin, attenuated
mucous membrane.
Diagnosis suggested by appearance of other secondary lesions-
mucous patches in pharynx, roseolar or papular rash, pyrexia,
enlargement of lymph nodes.
18. Tertiary syphilis
Only 1/3rd of cases of secondary syphilis progress to tertiary
stage.
Pathological lesion- gumma- begins as subcutaneous nodule,
progresses to involve overlying skin, and then breaks down to
form a punched out destructive ulcer.
Bony portion of septum most commonly involved
Lateral nasal wall, frontal sinus, nasal bones, floor of nose
may be involved late.

(HNE), which may increase apoptosis and the local inflammatory
response to injury
73. Clinical features
Rarely systemic symptoms
chronic nasal obstruction and bleeding,
change in shape of the nose and nasal regurgitation
variable degree of destruction of the septum, turbinates,
lateral nasal wall and floor
74. Diagnosis
positive human neutrophil elastase ANCA
Urine, blood and hair can be tested for cocaine if necessary
75. Treatment
No role for immunosuppression
Must stop using cocaine to prevent further progression.
Conservative treatment includes nasal douching, debridement
of necrotic areas and topical or systemic antibiotic therapy.
Surgical correction of septal perforation or nasal deformity
should not be attempted until the patient has been clear of
cocaine for at least 6–12 months.
76. NON-HEALING MIDLINE GRANULOMA
Synonyms
Stewart's granuloma
Midline lethal granuloma
Polymorphic reticulosis
Sinonasal lymphoma
T / NK cell lymphoma
Aetiology- caused by the Epstein-Barr virus.
77. Clinical Features
Usually present with aggressive destruction of the middle of
the face.
Usually arises in the nasal cavity and spreads to involve
adjacent structures including the orbits, oral cavity, skin and
paranasal sinuses.
intra-nasal granulomatous mass initially causes symptoms of
obstruction,discharge and bleeding.
79. Diagnosis
Histology-
infiltrates are polymorphic and
atypical cells may to be
arranged in a necrotizing
angiocentric growth pattern.
Immunohistochemistry is
usually positive for CD56, CD2
and cytoplasmic CD3
80. Treatment
Initially low dose radiotherapy was preferred
Now a days full course of radiotherapy is administered
covering the entire area
Chemotherapy is indicated only for high grade lesions
81. CHURG-STRAUSS SYNDROME
Eosinophil-rich and granulomatous inflammation involving the
respiratory tract and necrotizing vasculitis affecting small to
medium-sized vessels associated with asthma and
eosinophilia.
Bronchial asthma, nasal polyps, eosinophilia, systemic
vasculitis.
Treatment- oral steroids, treatment of nasal polyps.
82. Conclusion
Any patient with blood-stained discharge and crusting in the
nose has a granulomatous condition until proven otherwise.
No one test is completely reliable and a combination of
clinical findings combined with diagnostic investigations is
required.
Patients on long-term systemic steroids should be monitored
for complications.
Surgery is generally reserved for refractory cases or
complications of disease.
