This document discusses early breast cancer and its management. Early breast cancer includes in situ breast cancer and stages I and IIA breast cancers. The aims of treatment are possible cure, controlling local disease in the breast and axilla, breast conservation, preventing distant metastasis, and preventing local recurrence. Treatment may involve lumpectomy, lymph node assessment, and adjuvant radiation and/or chemotherapy. For a 40-year-old woman with early breast cancer, treatment would involve investigations like blood tests and imaging, followed by lumpectomy, sentinel lymph node biopsy or axillary dissection, and radiation or chemotherapy depending on risk factors. Breast conservation therapy is preferred when possible.

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.
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

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

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.

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.

perform BCS in the third trimester .
2. MULTIFOCAL/MULTICENTRIC DISEASE
3. History of PRIOR THERAPEUTIC IRRADIATION
to the breast region .

LYMPH NODE ???
The first axillary node draining the breast(by direct
drainage) is designated as the sentinel lymph node
(SLN)
It is the first node involved by tumour cells
Gives an idea about further spread of tumour to other
nodes.
Sentinel Lymph node Biopsy is done in all cases of
early breast cancers, T1 and T2 without clinically
palpable node
Not done for multicentric and multifocal tumours.

A skin-sparing mastectomy (preserves skin envelope and
inframammary ridge) may be performed with immediate
reconstruction, resulting in improved cosmesis:
The nipple-areolar complex, a rim of periareolar breast skin, and any
previous excisional biopsy or partial mastectomy scars are excised.

24. C. AXILLARY DISSECTION
INDICATIONS FOR AXILLARY DISSECTION
1) Preoperative diagnosis of axillary node metastasis
2) Positive SLN
3) Failed SLN biopsy or a recent inadequate ALND
4) Clinically suspicious nodes identified at surgery
5) Non availability of equipment for SLN biopsy
25. Adjuvant chemotherapy is given in appropriate
patients after completion of surgery.
All node-positive patients should receive adjuvant
chemotherapy.
Regimens are guided by the tumor biomarkers. Typical
regimens comprise four to eight cycles of a combination of
cyclophosphamide and an anthracycline, followed by a
taxane administered every 2 to 3 weeks.
Patients with ER-positive tumors receive adjuvant hormonal
therapy for 5 years. Tamoxifen is given to premenopausal
women, and aromatase inhibitors are given to
postmenopausal women (aromatase inhibitors are not used
in premenopausal women).
26. Node-negative patients may have increased disease-free
survival from adjuvant chemotherapy and/or hormonal
therapy.
Up to 30% of node-negative women die of breast cancer within 10
years if treated with surgery alone.
Node-negative patients who are at high risk and benefit the most from
adjuvant chemotherapy include those with
1.Tumors greater than 1 cm
2. Higher tumor grade
3. Her2/neu expression
4. Aneuploidy
5. Ki-67 expression
6.Increased percentage in S phase
7. Lymphovascular invasion, and
8. ER/PR-negative tumors.
27. Polychemotherapy in combination with tamoxifen
was superior to tamoxifen alone in increasing
disease-free and overall survival, especially in ER-
negative patients, regardless of tumor size.
Adjuvant whole-breast radiation after BCT decreases the
breast cancer recurrence rate from 30% to less than 7% at 5
years.
