The document discusses the development and benefits of the Milan System for Reporting Salivary Gland Cytopathology. It aims to standardize terminology for salivary gland FNA reports which previously lacked uniformity. The system categorizes specimens as non-diagnostic, non-neoplastic, atypia of undetermined significance, neoplastic (benign or uncertain malignant potential), suspicious for malignancy, or malignant. It is intended to improve communication between pathologists and clinicians, enhance patient care, and facilitate research by allowing standardized data collection across institutions. While validation is ongoing, the system provides a practical framework for uniform reporting of salivary gland cytology.

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.

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

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
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

Milan cytology reporting
1. Milan’s system of reporting
salivary gland cytology
Presenter: Dr.Argha Baruah
Moderator: Dr.ML Harendra Kumar
2. Introduction:
Salivary gland fine-needle aspiration (FNA) cytology has become an accepted method of evaluating
salivary gland tumors preoperatively
FNA of salivary gland tumors was shown to have a high specificity in differentiating benign and
malignant lesions (97%)
FNA falls flat in terms of sensitivity (80%)
3. Why we need a uniform reporting system?
Because of the wide diversity of tumors arising in the salivary glands along
with significant morphologic overlap.
Most pathologists report these specimens by employing heterogeneous
diagnostic terminology, specifically for indeterminate diagnoses, and that
clinician’s act variably based upon these reports.
Inconsistencies in reporting of salivary gland FNA specimens can have an
effect on the correlation between cytologic interpretation and surgical
outcome and finally has an impact on patient care
4.
5. The Bethesda system for reporting was created to address the inconsistencies
and the shortcomings of the terminology used for reporting FNA specimens. A
few authors have suggested that a similar classification is needed for
reporting of salivary gland FNA specimens.
Griffith et al. proposed a four category scheme that effectively stratified
salivary gland FNA specimens by overall risk of malignancy and risk of high
grade malignancy.The scheme was comprised of the following diagnostic
categories: benign, neoplasm of uncertain malignant potential (NUMP),
suspicious for malignancy and positive for malignancy; the overall risk of
malignancy for each category was 2%, 18%, 75.8%, and 100%, respectively.
6. Rossi et al. based on the experience of two academic centres with 709
salivary gland FNA specimens, stratified their cytologic diagnosis into the
following diagnostic categories with associated risk of malignancy:
nondiagnostic/inadequate—17%, benign—16%, neoplasm—6%, atypical—
53%,suspicious for malignancy/malignant—94%.
7. This led a group of experienced cytopathologists and histopathologists to attempt to create
a uniform cytological reporting scheme. The proposed system is based on key principles
developed for standardized terminology systems adopted for other body sites (ie, uterine
cervix, pancreas,thyroid, and urinary system)
8. The standardization effort started in September 2015 at the European Congress of Cytology,
which was held in Milan, Italy, under the umbrella of the American Society of Cytopathology
(ASC) and the International Academy of Cytology (IAC).
Subsequently, an international panel of 49 cytopathologists and histopathologists (the Milan
group) was organized to establish a unified effort under the title of “The Milan System for
Reporting Salivary Gland Cytopathology.”
Before starting the task of constructing a taxonomy, the Milan group invited the
international cytology and histology communities to answer a series of questions .Questions
were generated in accord with the current literature and experience of the authors in the
core group. The preliminary version was presented by Dr. William Faquin at USCAP 2016 in
Seattle
9. THE BENEFITS OF A UNIFORM REPORTING SYSTEM FOR SALIVARY
GLAND CYTOPATHOLOGY:
1. Improve communication between pathologists and clinicians
2. Improve patient care
3.Facilitate cytologic-histologic correlation
4.Promote research into the epidemiology, molecular biology,
pathology
5.Foster sharing of data from different laboratories for collaborative
studies
10. The Milan System for Reporting Salivary Gland
Cytopathology
1) Non diagnostic
2) Non-Neoplastic
3) Atypia of undetermined significance (AUS)
4) Neoplastic:
a) Benign
b) Uncertain malignant potential (SUMP)
5) Suspicious for Malignancy
6) Malignant
11.
12. Sample adequacy and evaluation:
Minimum number of lesional and nonlesional cells that cytopathologist require
to consider a aspirate as benign vs nondiagnostic/unsatisfactory was not
established.
13. Category I:Non-Diagnostic:
1)Insufficient quantitative and/or qualitative cellular material to make a
cytologic diagnosis
2)Includes aspirates with benign elements only
3)Includes non-mucinous cyst contents
4)Aspirate smears with cyst contents only (ie. granular debris and histiocytes
and few to no epithelial cells)
15. For aspirates containing only normal salivary gland elements, a cautionary
note is recommended.
Note: Clinical and radiologic correlations are recommended to ensure that
the aspirate is representative of the lesion; the findings in this aspirate do not
explain the presence of a salivary gland mass.
17. Category II: Non-Neoplastic:
Specimens lacking evidence of a neoplastic process:
1)Inflammatory, metaplastic, and reactive(i.e acute, chronic, and granulomatous
sialadenitis,sialadenosis, etc…)
2)Reactive lymph nodes (flow cytometry is needed)
Note: Clinico-radiological correlation is essential to ensure that the specimen is
representative of the lesion
19. REACTIVE PROCESS VS LYMPHOMA
IMMUNOPHENOTYPING combined with cytomorphology is the key to diagnosing
and subtyping reactive conditions vs lymphoma.
NOTE: For negative lymph nodes, caution is warranted: A note suggesting
repeat FNA or tissue biopsy if lymphadenopathy persists
22. Category III: Atypia of
Undetermined Significance (AUS):
1. Cannot entirely exclude a neoplasm.
2. Heterogeneous category
3. A majority will be reactive atypia or poorly sampled neoplasms
4. Specimens are often compromised (eg, air-drying, blood clot)
5. Should be used rarely (<10 % of all salivary gland FNAs)
23. The diagnosis of AUS can be used in the following scenarios:
•Squamous, oncocytic, or other metaplastic changes indefinite for a neoplasm
•Low cellularity specimens that are suggestive of, but not diagnostic of a neoplasm
•Specimens with preparation artifacts hampering distinction between a non-neoplastic and
neoplastic process
•Mucinous cystic lesions with an absent or very scant epithelial component
•Salivary gland lymph nodes or lymphoid lesions which are indefinite for a
lymphoproliferative disorder
•Reactive and reparative atypia indefinite for a neoplasm
30. SUMP(Salivary gland neoplasm of uncertain
malignant potential)
Reserved for: Diagnostic of a neoplasm; however, a diagnosis of a specific entity
cannot be made.Amalignant neoplasm cannot be excluded.
SUMP ENTITIES:
Cellular Basaloid Neoplasm
Oncocytoid Neoplasm
Neoplasm with Granular and/or Vacuolated or clear cells
34. The inability to separate these tumor types with greater accuracy
preoperatively is made more frustrating by the fact that the surgical approach
can be quite different.
The application of a monomorphic cellular basaloid neoplasm with fibrillary
stroma was meant to capture pleomorphic adenomas .
The finding of hyaline stroma was predicted to identify those neoplasms of
higher risk, specifically adenoid cystic carcinoma
35. Category V: Suspicious for Malignancy
Aspirates which are highly suggestive of malignancy but not definitive.Atypia
concerns malignancy but sample falls short for clear diagnosis.
Often high grade carcinomas with limited sampling or other limitation
Markedly atypical cells with poor smear preparation, poor cell preservation,
fixation artifact, or obscuring inflammation and blood
Presence of limited cytologic features of a specific malignant lesion (e.g.
adenoid cystic carcinoma, mucoepidermoid carcinoma, acinic cell carcinoma)
in an otherwise sparsely cellular aspirate
36. Presence of markedly atypical and/or suspicious cytologic features in a subset
of cells but admixed with features of a benign salivary gland lesion.
Atypical features can include prominent nucleoli or macronucleoli,
anisonucleosis, increased nuclear to cytoplasmic ratio, nuclear molding,
prominent nuclear pleomorphism, atypical mitosis, and clumped, coarse
chromatin
37. Malignancy:
Aspirates which are diagnostic of malignancy
Sub-classify into specific types and grades of carcinoma: e.g. low grade vs
high grade
"Other" malignancies such as lymphomas, sarcomas and metastases are also
included in this category and should be specifically designated.
42. Rarely there was enough material on slides or in cell blocks to perform
ancillary studies.
The use of p63/calponin for myoepithelial cells, mucicarmine/D-PAS for MEC,
and CD117/DOG-1 have been shown to have some usefulness in differentiating
ACC from polymorphous adenocarcinoma and PA.
Greater than 90% of the ancillary studies are performed on cell block material
and very less are performed directly on cytologic preparations.
43. Ancillary studies useful in:
Basaloid neoplasm
Oncocytic neoplasm
Metastatic lesions
Rule out lymphoma
Subtype a high grade carcinoma
Subtype a low grade carcinoma
44.
45.
46. t(6:9) MYB oncogene-NFIB transcription factor
In salivary gland, this finding by FISH is specific for AdCC
53. Pitfalls in Milan’s
It should be noted that the cumulative risk of malignancy for each diagnostic
category may represent an unintended overestimation due to: institutional
referral patterns (large academic and referral centers vs.community
practice), surgical selection bias based on factors such as large size of the
mass, high risk clinical radiologic features.
54. The category of atypia of undetermined significance (AUS) is not well
defined. The cases we classified as AUS were those in which the differential
was between a retention cyst (ie, a nonneoplastic lesion) and a low-grade
mucoepidermoid carcinoma (ie, a malignant neoplastic lesion).
Therefore, these cases were categorized as atypical because we were not
sure even about the neoplastic nature of the lesion.
Even members of the Milan group are concerned about the overuse of the
term “AUS” as noted in other cytological systems.
Still the categories of division are very subjective.
Robust testing is still going on in terms of validity and reproducibility
55. Summary:
Salivary gland cytology presents many diagnostic challenges
The Milan System for Reporting Salivary Gland Cytopathology will help to produce
a more uniform diagnostic structure. It is a practical classification system that is
user friendly and can be internationally accepted with a useful format for
clinicians.
Improved communication between treating clinician and pathologist
Improved patient care and help in multicentric collaborative study .
Availability of IHC and molecular markers can greatly improve the accuracy of
salivary gland FNA
