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.

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

Pulmonary Thromboembolism - etilogy, types, medical- Surgical and nursing man...VarunMahajani
Disruption of blood supply to lung alveoli due to blockage of one or more pulmonary blood vessels is called as Pulmonary thromboembolism. In this presentation we will discuss its causes, types and its management in depth.
These lecture slides, by Dr Sidra Arshad, offer a quick overview of physiological basis of a normal electrocardiogram.
Learning objectives:
1. Define an electrocardiogram (ECG) and electrocardiography
2. Describe how dipoles generated by the heart produce the waveforms of the ECG
3. Describe the components of a normal electrocardiogram of a typical bipolar leads (limb II)
4. Differentiate between intervals and segments
5. Enlist some common indications for obtaining an ECG

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.
Knee anatomy and clinical tests 2024.pdfvimalpl1234
This includes all relevant anatomy and clinical tests compiled from standard textbooks, Campbell,netter etc..It is comprehensive and best suited for orthopaedicians and orthopaedic residents.
2. •Septicarthritisisinflammation of a synovial
membrane with purulent effusion into the joint
capsule, due to infection.
Synovial membrane
Membrane surrounding joint
cavity
Produce synovial fluid
Contain rich capillary networkfor
phagocytic and hyaluronate-
producing function
3. Causes of septic arthritis
Bacterial
•Non gonococcal
arthritis
•Gonococcal
arthritis
others
•Virus
•Fungi
•Mycobacteria etc.
4. Most common form of spread
Usually affect people with underlying medical problem
May result from penetrating trauma
Introduction of organisms during diagnostic and surgical
procedures. For eg arthroscopy and intra-articular injection
More common in children.
Osteomyelitis usually begin in the metaphyseal region,
from which it breaks through the periosteum into the
joint.
5. Synovial membrane is highly vascularised.
↓
Bacteria can easily enter synovial joint via blood stream.
↓
There will be inflammatory reaction with seropurulent exudate and increase
in synovial fluid.
↓
As pus appear in the joint, the articular cartilage is eroded and destroyed.
Partly by the bacterial enzyme, and partly by the enzyme released from
synovium, inflammatory cell and pus
Infant
Destroy the epiphysis,
which is still largely
cartilaginous.
Children
Vascular occlusion lead
to necrosis of
epiphyseal bone
Adult
Effect confined on
articular cartilage
Extensive erosion can
occur due to synovial
proliferation and
ingrowth
6. a) In the early stage, there is an acute synovitis with a purulent joint effusion
b) Soon the articular cartilage is attacked by bacterial and cellular enzyme.
c) If infection is not arrested , the cartilage may be completely destroyed
d) Healing then leads to ankylosis
7. ..
.•Within 24-48 hrs of bacterial invasion:
•Infiltration by neutrophils
•Vascular congestion
•Synovial proliferation
•Within 1 week following bacterial
invasion:
•Continual purulent effusion
•Continual synovial proliferation
•Infiltration by mononuclear cells
•Granulation tissue
•Abscess development
•Within 10 days after abscess
formation:
•Cytokine induced protelytic enzymes
arereleas
ed•End resultis joint destruction and or
systemic sepsis
8. If leftuntreated,it will spread to the underlying bone
and out of joint to form abscess and sinus.
Healingwith:
1.Complete resolution
2.Partial loss of articular cartilage and fibrosis of joint
3.Loss of articular cartilage and bony ankylosis
4.Bony destruction and permanent deformity
9. ACUTE BACTERIAL ARTHRITIS
•Staphylococcus Aureus – 50%
•Streptococcus species, such as Streptococcus
viridans, S Pneumoniae & group B streptocci
•Gram negative bacilli – 10% - E.coli & pseudomonas
– More common
•Sites : Monoarticular involvement - -85% , knee –
most common
•Other – hip , wrist, shoulder & ankle
•Sternoclavicular and sacroiliac joint -
10. PREDISPOSING FACTORS:
•Artificial joint implants
•Bacterial infection elsewhere in body
•Chronic illness or disease (such as diabetes,
rheumatoid arthritis, and sickle cell disease)
•Intravenous (IV) or injection drug use
•Medications that suppress immune system
•Recent joint trauma
•Recent joint arthroscopy or other surgery
11. In new born infants
More on septicaemia
Rather than joint pain
Baby is irritable &
refuse to feed
Tachycardia with fever
Joints are warmth,
tenderness, resistance
to movement
Umbilical cord and

Often in the superficial
joint(knee, wrist or ankle )
Joints painful, swollen
& inflamed.
Warmth and marked

look for gonococcal
infection or drug abuse.
Patient with
rheumatoid arthritis and
especially those on
corticosteroid may
develop “silent” joint
infection.
12. Physical examination:
•Lower limb antalgic limp / cannot walk
•Upper limb affected part is closedly guarded
•Marked tenderness, active and passive range of
motion are limited
•Examine for synovial effusion, erythema, heat and
tenderness.
•Spasm of muscles around the joint may be
marked.
•Patient may hold the joint in a position to reduce
the intra-articular pressure to minimize pain.
14. Synovial fluid analysis
Aseptic technique is used during aspiration of synovial fluid.
Avoid taken from infected site of skin.
The fluid is then analyzed by gross andmicroscopic
examination and culture.
Gross examinations include appearance, volume,
viscosity,
Microscopic examinations include leucocyte count,
staining of smears,, protein.
Finally, culture and sensitivity for definitive diagnosis
and treatment.
15. X ray
Early Stage – Normal
Look for soft tissue swelling, loss of tissue planes,
widening of joint space and slight subluxation due to fluid in
joint. Gas may be seen with E. coli infection
Late stage – Narrowing and irregularity of joint space
Plain film findings of superimposed osteomyelitis may
develop (periosteal reaction, bone destruction, sequestrum
formation).
16. Narrowing of joint space and irregularity of
subchondral bone.
Joint space loss
subchondral erosions and
sclerosis of the femoral
head
osteonecrosis and
complete collapse of
the femoral head
17. Ultrasonography-
•More reliable in revealing a joint effusion in
early cases.
•Widening of space between capsule and
bone of > 2mm indicates effusion.
•Echo-free transient synovitis
•Positively echogenic septic arthritis
18. CT scans, MRI, and bone
scans
•CT scans – soft tissue swelling, joint
effusions, abscess formation, guide joint
aspiration, monitor therapy and planning
operative approaches.
•MRI – extent of infection, diagnosing
infections that are difficult to access, better
anatomical detail.
•Bone scans- detect localized areas of
inflammation.
19. Treatment :
• The first priority is to aspirate the joint and examine the fluid,
treatment is then started without further delay.
• General measures:
- analgesics
- iv fluids
• Splintage-
-the joint must be rested either on a splint or in a widely split
plaster
-in neonates and infants, with hip infection the joint is held
abducted and 30 degree flexed, on traction to prevent
dislocation.
• Antibiotics –
- treatment is started once blood and samples are obtained.
-empirical treatment is started depending on most likely organism.
20. Surgical Drainage
Indications:
-Joints that don’t respond to antimicrobial therapy and daily
arthrocentesis
-Any joint with limited accessibility, including the sternoclavicular or
the hip joint
-Patient with underlying disease( DM,RA, immunosuppression etc)
need more aggressive treatment with earlier surgical intervention
Arthroscopic debridement and copious irrigation with normal
saline – more frequently in knee joint septic arthritis
21. -Bone destructionand dislocation of the
joint(esp Hip)
•Cartilage destruction
-may lead to either fibrosis or bony ankylosis
- in adult partial destruction of the joint will result in
secondary osteoarthritis
•Growth disturbance
- presenting as either localised deformity or shortening
of the bone
22. Gonococcal arthritis
- results from gonococcal infection (colonization of
urethra, cervix, pharynx)
-Sexually active healthy persons
-More common in women than men
-Congenital Complement deficiency
23. Clinical features-
•Disseminated gonococcal infection- fever, chills,
rash, small no. of papules that progresses to
haemorrhagic pustules present on trunk and
extensor surfaces of distal extremities.
•Migratory arthritis and tenosynovitis of the knees,
hand, wrists, feet and ankles.
•Cultures of synovial fluid are negative, blood
cultures positive < 45%, synovial fluid may be
difficult to obtain , usually contains 10000 – 20000
leucocuytes/micro L.
24. Treatment-
•Initiallly, ceftriaxone ( 1 g IV every 24 h)
•Local and systemic signs resolve, oral antibiotic
(ciprofloxacin 500mg BD) should be started for 7
days.
•Penicillin susceptible- amoxiciilin 500 mg TDS .
•Suppurative arthritis usually respond to needle
aspiration and antibiotic treatment for 7-10 days.
25. Mycobacterial arthritis
• 1% of all cases of TB and 10% of extrapulmonary cases
• Pathology –
• Enters the body via lung(droplet infection) or the gut( swallowing
infected milk priducts), rarely through skin
• It causes granulomatous infection associated with tissue necrosis and
caseation.
• Primary complex – initial lesion in lungs , phayrnx or gut with
lymphatic spread to regional lymph nodes.
• Secondary spread- widespread dissemination via blood stream
giving rise to extrapulmonary lesions.
• Tertiary lesion- foci developing to destructive lesions.
• Once they get foothold they elicit a chronic inflammation.
26. synovium involved
becomes thick and oedematous, marked effusion
pannus of granulation tissue develops, articular cartilage
slowly destroyed, increased vascularity causes osteopenia
if unchecked, caseation and infection extend into surrounding
soft tissues and produce cold abscess
may burst forming sinus or tuberculous ulcer
27. Clinical features
•Previous history of infection or recent contact with
TB
•A long history of pain and swelling
•Marked synovial thickening
•Involvement of only one joint
•Severe muscle wasting
•Enlarged and matted regional lymph nodes
•Night cries, fever, night sweats, loss of weight.
28. treatment
•Rest
•Chemotherapy : two months course of
isoniazide(600mg), rifampicin(450mg),
pyrazinamide(1500mg), ethambutol(1200mg) thrice
weekly and then 4 months course of
isoniazide,ethambutol rifampicin thrice weekly.
29. Fungal arthritis
•Infection causes granulomatous reaction, often
leading to abscess formation, tissue destruction and
ulcer formation
•Superficial and deep infections.
•Superficial mycoses- primarily infections of skin and
mucous membrane. Eg, madurmycoses, sporothrix ,
candida, actinomycoses.
•Deep mycoses- blastomyces, histoplasma ,
Cryptococcus, coccidioides, aspergillus. Gain entry
through lungs.
30. Madurmycosis-
cut in foot
spread through subcutaneous tissues and along
the tendon sheaths
Bones and joints are infected by direct invasion,
local abscesses form and break through the skin as
multiple sinuses.
31. Clinical features
Subcutanoeus nodule, tender
Swollen foot, indurated
Discharging sinuses and ulcers
X- rays : multiple bone cavities , progressive bone
destruction
Organism can be identified in sinus discharge or
biopsy
33. Viral arthritis
•Infects synovial tissue during systemic infections or
by provoking an immunologic reaction that involves
joints.
•Rubella- arthralgia , frank arthritis within 3 days of
rash following natural infection with rubella
•Parvovirus B 19- arthritis, arthropathy , stiffness of
joints
•Acute Hep B- arthralgia, fever, urticarial 2 weeks
before onset of jaundice.
