This document discusses various types of artefacts that may be observed during a post-mortem examination and could be misinterpreted. It defines an artefact as something not naturally present but introduced after death. Artefacts are classified as: 1) due to resuscitation measures 2) occurring between death and autopsy 3) due to pre-mortem injuries or lesions 4) developing during the autopsy. Examples of artefacts from resuscitation include rib fractures from CPR and laryngeal injuries from intubation. Artefacts between death and autopsy include regurgitation, hypostasis, and embalming changes. Differentiating post-mortem from ante-mortem injuries is also discussed.

Colposcopy training part 1 ,DR. SHARDA JAIN Dr. Jyoti Agarwal / Dr. Jyoti Bha...Lifecare Centre
Definition used in the consensus guidelines ASCCP +24 organizations 2013
Colposcopy
Colposcopy is the examination of the cervix , vagina and, in some instances the vulva, with the colposcope after the application of a 3--5% acetic solution coupled with obtaining colposcopically – directed biopsies of all lesions suspected of representing neoplasia
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.

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

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
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
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!
Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
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.

Literature regarding “ARTEFACT”
Definition
Classification
Description
Medico-legal Importance
Take home message
3. British variant of ‘artifact’.
First used in 1821.
Origin – Latin.
Meaning by dissection of word ‘artefact’-
‘arte’ – skill
‘fact’ from ‘factum’ from ‘facere’ – something made.
Cont.
4. 2 meanings:
A simple object created by humans, from a particular period in
past for any practical purpose which have cultural or historical
interest, so usually used by historians. (a favorite word among
them)
A product of artificial characters, usually due to extraneous
agency.
or
Something observed or evident that is not naturally present
but occurs as a result of outside source or procedure.
(a non-favorite word among doctors)
5. Definition
Artefacts means anything which is not real but something
artificial.
It is a change or feature which was not physiologically or
even pathologically present in the body tissues before
death in natural course of events, but which have been
caused or introduced into the body after death, often
leading to much confusion about its nature and causative
effect and often resulting in misinterpretation of medico-
legally significant findings.
6. Classification
Four types
1. Due to resuscitative or therapeutic measures
2. Between death and autopsy
3. Due to injuries or lesions of organs before death
4. During post-mortem examination
7. Due to resuscitative or therapeutic
measures
1. From the very outset, I want to state that HISTORY OF
PATIENT is of utmost importance in every branch of medical
science, either clinical or non-clinical, so is applied to
Forensic Medicine.
2. Marks of injection & defibrillator on chest
3. CPR – fracture of ribs & sternum
a) Can cause haemothorax & haemopneumothorax
b) Fat embolism from fractured ribs or sternum
c) Laceration of spleen, liver and diaphragm
4. Positive pressure ventilation – emphysema, sub-pleural air
blebs, tension pneumothorax.
Cont.
9. 5. Counter irritation Chinese style on neck – extravasation
of blood under skin – suspicion of throttling.
6. Endo-tracheal intubation – inexperienced hands – injury
to larynx and adjacent tissue – suspicion of foul play.
7. Carotid Angiography – neck muscle bruise – suspicion
of throttling.
8. Antemortem surgeon’s intervention on wounds may
mislead autopsy findings.
10. Between death and autopsy
1. Agonal artefact – ‘agonal’ the struggle that precedes
death.
a. Common agonal artefact is REGURGITATION &
ASPIRATION
b. Vascular collapse or shock before death
May prevent any significant bleeding
Crux: Accidental Deaths Can Also Have Congested Viscera.
Ante mortem Agonal Reaction Post mortem Agonal Artefact
Stomach contents aspirated and
goes to lower respiratory tract
mixed with fluid and mucus
choking effect death
Never reaches to lower
respiratory tract.
11. • Embalming : chemical treatment
of dead body to protect from
decay.
• Trochar insertion for arterial
access from
• Existing wound – may change
size shape direction , can create
false tracks
• Freshly created wound – may
simulate stab or gunshot wound
2.
Embalming
Artefact:
13. • Embalming fluid may extravasate blood from
veins & arteries, may mistaken as bruise;
Or
small bruise large bruise
• Embalming fluid interferes in toxicological
analysis.
14. 3. Internment & Exhumation Artefacts
Fungus on
injuries &
natural orifices
Area underlying
simulate bruise
Digging may
produce fracture
of bones
16. 4. Artefacts due to handling of cadavers
• From transportation
• Abrasion, laceration, blood spots on clothes and body
which was absent in original.
• From careless handling
• Bruise in occipital area due to head bumping on hard
surface, differentiated by wiping off the bruise.
• Fracture ribs and vertebras.
• Weak, osteoporotic bones may get fractured due to
counteract the Rigor Mortis.
• Brush abrasions on back by dragging.
17. Abrasion
Laceration
Antemortem Postmortem
Looks brownish or reddish Brown or parchment like
Scab is noticed if gets older Scab is never noticed
Bleeding surface present if fresh No bleeding surface is evident
Healing is evident No such thing can ever happen
Can be found on any part of body Usually on bony prominences
Surface is moist Surface is dry
Antemortem Postmortem
Vital reactions will be seen No vital reaction will be seen
Margin is bruised No bruising is seen on margin
19. Bruise – it is essentially a vital phenomena
Antemortem Postmortem
Swelling Cannot be similar as antemortem
Evidence of extravasation of blood Can be produced like antemortem to
some extent with in 2 minutes to
maximum of 2-3hrs, that to on the
tissue which can be forcibly
compressed against the bone.
Extravasated blood will impart
colouring to the affected area
But disproportionate to effect of force,
bruise will always be less
Colour changes denote resolution of
bruise
Occipital postmortem bruise simulate
antemortem bruise , difference is
absence of vital reaction apart from
microscopy.
Detection of enzyme ascertain
antemortem origin eg. – esterase,
aminopeptidases, acid phosphatase,
alkaline phosphatase
20. False simulated artificial bruise
• Irritant substances can do so
• Done to substantiate a false charge of assault
• By plumbago zeylanica, rolsea, semicarpus anacardium
• Margins contain tiny vesicles containing acrid serous
fluid
• Surrounding skin shows inflammatory reaction
• Diagnosis is made by incision, clot cannot be wiped off
21. Clotted blood
Postmortem blood clot is of 2 types:
Red current jelly: forms rapidly, soft, lump, slippery,
uniformly dark red.
Chicken fat: forms when clotting occurs slowly, consist of
2 layers:
Reddish moist lower layer: consist of red cells, soft, lumpy.
Bright yellow upper layer: of fibrin and serum, jelly like.
Antemortem Postmortem
It cannot be wiped off as it
fibrin.
It can be wiped off easily
because it does not have
fibrin.
22. 5. Artefacts due to Rigor Mortis
• To move the body, breaking is done, resulting in
asymmetrical Rigor Mortis
• May cause misinterpretation of Time Since Death.
• Heat/Cold stiffening may pose as an artefact against Rigor
Mortis.
• How to differentiate heat/cold stiffening to Rigor Mortis:
23.
24. Gas stiffening may simulate Rigor Mortis, but with the
following features one can easily differentiate it from Rigor
Mortis:
Putrefactive changes will be seen, as it is due to inflation of
tissue spaces by gases of putrefaction, which is not seen in
heat or cold stiffening.
No particular order of appearance or disappearance as in
Rigor Mortis
Joints are not tight, so can be moved easily.
No muscle shortening as in heat stiffening.
Stiffening will pass if gas is allowed to escape by incisions over
the areas.
32. Decomposition
artefacts:
• It brings lots of significant
changes which can be mistaken
as artefact on naked eye
examination. Some of the
following are:
33. Sl. No. Artefact Misinterpretation Remark

1. Artefacts in respect to gun-shot wounds
• Surgical/Medical tending – cleaning debridement
etc, removes gun powder, and changes the all over
character, as in J F Kennedy murder case
• Decomposition causes peeling of epidermis,
disintegration of tissue
• Trochar insertion in embalming – track distortion,
false track, detection of direction of fire may
become difficult
49. 2. X-ray Artefact
• In a dead body x-ray for gun-shot bullet, false
missile shadow can be found due to, bullet in
shirt pocket, bullet not fired, bullet between shirt
fold etc.
3. Artefacts induced by criminals
• Dismemberment of body part, mutilation
• Post mortem injuries
50. Artefacts during Post Mortem
Examination
1. Injury to visceral organs – ante mortem injuries
2. Fracture of skull bones, may continue with antemortem
fracture, misinterpretation of whole fracture
3. Hyoid and thyroid fracture during forceful extraction the
heart and lungs
4. Bleeding in neck; anti/post mortem ?
Can be told only after enzyme study.
So, take out heart, lung, brain before neck.4
51. Medico Legal Importance
Wrong conclusion as to
• Cause of death
• Mode of death
• Nature of death
• Antemortem or Postmortem
Unjustified suspicion of foul play
Misguided direction to investigating officer
Miscarriage of justice
